3 * Removed the silc_ske_check_version function and created
4 a SilcSKECheckVersion callback. Added also a function
5 silc_ske_set_callbacks that is now used to set all SKE
6 callbacks. The callback functions are not given to
7 the SKE functions anymore, but this function is used to
10 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
12 * Added `silc_version' argument to the silc_client_alloc
13 to define the version of the application for the library.
14 The library will use the version string to compare it
15 against the remote host's (usually a server) version
16 string. Affected file lib/silcclient/silcapi.h
18 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
20 * Do not add regex.h for WIN32. The affected file
21 includes/silcincludes.h.
23 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
24 not work yet 100%. It generates the DLL's automatically
25 when compiling with --with-win32 under cygwin.
27 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
29 * lib/contrib/regex.c is not compiled on WIN32.
31 * Added silc_net_get_socket_opt function to the
32 lib/silcutil/silcnet.h.
34 * Added includes/silcwin32.h for WIN32 specific includes
37 * Do not use ptime structure or any of the posix process
38 functions on WIN32 in lib/silccrypt/silrng.c.
40 * Added silc_gettimeofday to provide generic function
41 for struct timeval on all platforms. Added the function
42 to lib/silcutil/silcutil.h.
44 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
46 * Moved the lib/silccore/silcsockconn.[ch] to the utility
47 library as they clearly belong there. As a plus side we
48 can make the actual socket connection routines platform
51 Added also new generic function silc_socket_read and
52 silc_socket_write (that used to be silc_packet_[read/write].
53 The implementation of these are platform specific.
55 * Added WIN32 specific routines of silc_socket_[read/write]
56 to lib/silcutil/win32/silcwin32sockconn.c.
58 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
60 * Added preliminary support for native WIN32 compilation under
61 cygwin (using the -mno-cygwin option for GCC) to the
62 ./configure.in.pre. The --with-win32 now prepares the
63 compilation for native WIN32.
65 * Rewrote the SILC Scheduler interface in the file
66 lib/silcutil/silcschedule.h. The scheduler is now context
67 based and does not have anymore any global static scheduler.
68 Moved the Unix scheduler to the lib/silcutil/unix/ directory
69 and created lib/silcutil/win32 directory for WIN32 based
72 * Added Unix specific network routines to the
73 lib/silcutil/unix/silcunixnet.c and the old
74 lib/silcutil/silcnet.c includes now only generic routines.
76 Added WIN32 specific network routines to the
77 lib/silcutil/win32/silcwin32net.c.
79 * Added Unix specific utility functions from the
80 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
82 * Added WIN32 SILC Scheduler to the file
83 lib/silcutil/win32/silcwin32schedule.c. The code is of course
86 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
88 * Do not handle JOIN notify in the server if the target client
89 is not registered (idata->registered == FALSE). The affected
90 file is silcd/packet_receive.c.
92 * Update the nickrec->founder in event_cumode in the Irssi SILC
93 client. Affected file irssi/src/silc/core/silc-channels.c.
95 * Fixed the CUMODE_CHANGE notify handling in the server when
96 server and router are announcing their clients on channels.
97 Now the mode changes are saved and notified correctly. The
98 affected file is /silcd/packet_receive.c.
100 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
101 They really did not replace the cache entry in the ID Cache.
102 Now they do that. Affected file silcd/idlist.c.
104 * Fixed the KICK notify handling in the Irssi SILC client to
105 update the channel records so that the kicked client does not
106 appear to be on the channel. The affected file is
107 irssi/src/silc/core/silc-channels.c.
109 * Always update the conn->current_channel when executing command
110 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
112 * Fixed the KILL notify handling in Irssi SILC client to remove
113 the killed client on all channels.
115 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
117 * Fixed the silc_parse_command_line to remove extra spaces
118 from the start and end of the arguments. Affected file is
119 lib/silcutil/silcutil.c.
121 * Cancel and free any active protocol in the function
122 silc_server_close_connection. Affected file silcd/server.c.
124 * Cancel and free any active protocol in the function
125 silc_client_close_connction. Affected file is
126 lib/silcclient/client.c.
128 * Do not execute the KILL command for clients that are in
129 history (ie. they are not in the network). Affected file is
132 * Fixed KILL notify handling, client does not crash anymore.
133 Affected file irssi/src/silc/core/silc-channels.c.
135 * Reduced the default packet buffer size from 2048 to 1024 in
136 lib/silccore/silcpacket.c.
138 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
139 counter to the SKE context that is incresed when the SKE library
140 performs async operation outside the library. If the outside
141 process frees the SKE context and FREED status will be set
142 and the library will detect after the sync operation that the
143 libary is freed. The affected files are
144 lib/silcske/silcske[_status].[ch].
146 * Resolve the client entry information in the function
147 silc_client_channel_message to assure that NULL pointer is not
148 passed as client entry to the application. */
150 * Fixed the task timeout calculation to assure that there is
151 never negative timeouts. The affected file is
152 lib/silcutil/silcschedule.c.
154 * Fixed the channel user mode notification sending in server.
155 It was sent point-to-point to the router (or to server by router)
156 but it needs to be destined to a channel. The routines now
157 supports sending the channel user mode notifys to the channels
158 when announcing clients and channels. Affected files are
159 silcd/server.c and silcd/packet_receive.c.
161 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
162 It did not actually replace the old channel entry in the cache.
163 Affected file lib/silcclient/client_notify.c.
165 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
167 * Fixed a possible crash in silc_packet_send_prepare. It now
168 assures always that there is enough space in the buffer and
169 at the tail area of the buffer (for MAC).
171 Fixed the inbound buffer reallocation in silc_packet_read.
172 It was old code and did not handle the reallocation correctly.
175 The affected file is lib/silccore/silcpacket.c.
177 * Fixed buffer overflow in silc_parse_nickname in the file
178 lib/silcutil/silcutil.c.
180 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
182 * make install generates new server keys only if there is not
185 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
188 Added check that if the NOREPLY is set then we will not send
189 the away message. This avoids infinite loop of away messages
190 if both clients are away. The affected file is
191 lib/silcclient/client_prvmsg.c.
193 * Fixed client crash if /NICK was given without arguments.
194 Affected file lib/silcclient/command.c.
196 * Server does not send the invite list in INVITE command back
197 to the client if the list was not altered. Added this notion
198 to the protocol spec as well. Affected file silcd/command.c.
200 Fixed possible crash in INVITE command by checking the
201 value of silc_server_get_client_route command.
203 * Fixed the INVITE notify type handling. The arguments are now
204 taken in correct order and client does not crash. The affected
205 file is irssi/src/silc/core/silc-channels.c.
207 Removed the "Inviting xxx to channel" message from the
208 client library away and let the application handle it.
209 Affected file lib/silcclient/command.c. Added that message
210 to Irssi SILC client's message formats.
212 * Fixed CMODE command crash in client. It now checks the
213 amount of arguments correctly and does not crash. The affected
214 file is lib/silcclient/command.c.
216 * Do not create new channel automatically in silc_channels_join
217 but check whether the channel by that name already exists.
218 Affected file irssi/silc/core/silc-channels.c.
220 * Do not send the SERVER_SIGNOFF to router if the disconnected
221 entity was the router. Affected file silcd/server.c.
223 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
224 SILC client as it was missing from there.
226 Added the handling of the KICK notify to the Irssi SILC client
227 as it was missing. Added "you have been kicked" message to
228 Irssi SILC client's message modules formats.
230 Added the handing of the KILL notify to the Irssi SILC client
231 as it was missing. Added the kill message module formats
234 The affected file is irssi/src/silc/core/silc-channels.c.
236 * The router did not save the channel mode the server announced.
237 Affected file silcd/packet_receive.c.
239 * Fixed a possible crash in INFO command in server. If the
240 server did not provide the server info it crashed. Affected
241 file silcd/command.c.
243 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
245 * Fixed the GETKEY command in the server to check also the
246 global list. Otherwise the GETKEY would not work correctly
247 in normal SILC server. Affected file silcd/command.c.
249 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
251 * Fixed GETKEY crash, it crashed if the command did not succseed.
253 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
256 is now real and not just an macro interface to GMP.
258 Removed the entire GMP from the source tree and imported new
259 NSS MPI library instead. Reason for removing GMP is that it is
260 extremely large and compiles extremely slow. The NSS MPI
261 is only a few files and compiles in less than 10 seconds.
262 The speed is also about the same as GMP. The MPI is imported
265 If the system has GMP installed we will still use the GMP.
266 If it is not then the NSS MPI will be compiled.
268 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Merged a long nickname (127 characters long) crash bugfix from
271 Irssi CVS tree. Affected file irssi/src/core/misc.c.
273 * Merged a freed memory reference bugfix from Irssi CVS tree.
274 Affected file irssi/src/core/commands.c.
276 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
278 * Added the server's public key sving and verification to the
279 server when performing the SKE. This was missing and the
280 remote server's (or router's) public key was accepted without
281 checking whether we have it previously or trust it at all.
282 Affected file silcd/protocol.c.
284 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
286 * Check in the silc_server_timeout_remote if protocol is active
287 and make sure that the protocol's final callback is called so
288 that all memory if freed. Affected file silcd/server.c.
290 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
292 * silc_server_whois_send_reply crashed the server if the nickname
293 was 127 characters long. Affected file silcd/command.c.
295 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
297 * Added sanity check to the silc_server_new_client. If the hostname
298 is provided inside username then check that the provided hostname
299 really is the same as the resolved one. If the hostname was not
300 resolved then check it from the public key. Affected file is
301 silcd/packet_receive.c.
303 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
304 if the server disconnected us and the connection is not valid
305 anymore. Affected file irssi/src/silc/core/silc-channels.c.
307 * Moved the silc_client_[chmode|chumode|chumode_char] away from
308 the library to the lib/silcutil/silcutil.[ch].
310 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
312 * Close log file after open. Affected file
313 lib/silcutil/silclog.c.
315 * Check whether sock == NULL in silc_client_send_packet and return
316 if it is. Affected file lib/silcclient/silcclient.c.
318 * Check rec->entry == NULL in the Irssi SILC Client before
319 sending the channel message. Affecte file is
320 irssi/src/silc/core/silc-servers.c.
322 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
324 * Merged a splitted window bugfix from Irssi CVS tree. The
325 affected file is irssi/src/fe-text/textbuffer-view.c.
327 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
328 It did not print nickname.
330 * Improved the distributions system a bit.
332 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
335 irssi/src/fe-text/gui-window.c.
337 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
338 to in-active server. The affected file is
339 irssi/src/silc/core/client_ops.c.
341 * Resolve the client in USERS command reply if the entry does
342 not have username resolved. The affected file is
343 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
344 command to WHOIS command to really resolve stuff. The USERS
345 is not used any more in any critical section so WHOIS can
346 be used even though it might be slower than IDENTIFY.
348 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
351 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * Changed the protocol API a bit more consistent in the
354 lib/silccore/silcprotocol.[ch].
356 * Changed the following headers to ROBODoc format:
358 lib/silccore/silcpayload.h
359 lib/silccore/silcprotocol.h
360 lib/silccore/silcsockconn.h
362 All core library headers are now formatted.
364 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
366 * Fixed a bug in Irssi SILC client; do not show that you are
367 server/router operator if you really are not. Affected file is
368 irssi/src/silc/core/client_ops.c.
370 * Renamed silc_command_free_payload to silc_command_payload_free.
371 Affected file lib/silccore/silccommand.h
373 * Added silcmath.h to include the prototoypes of various routines
374 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
377 * Changed the following headers to ROBODoc format:
379 lib/silccore/silcchannel.h
380 lib/silccore/silccommand.h
381 lib/silccore/silcid.h
382 lib/silccore/silcidcache.h
383 lib/silccore/silcmode.h
384 lib/silccore/silcnotify.h
385 lib/silccore/silcpacket.h
386 lib/silcmath/silcmath.h
388 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
390 * Added checking to the server code not to start the server if
391 ciphers and stuff are not configured properly. Affected files
392 silcd/serverconfig.[h] and silcd/server.c.
394 * Changed the layout of the header files of the public interfaces
395 in the SILC libraries. The new layout supports ROBODoc
396 documentation tool (and some others) so that it is easy to create
397 a library reference manual. All the other headers and source
398 code must still follow the CodingStyle document. Also source
399 code must not include these ROBODoc stuffs, only the headers.
400 Furthermore, all public interface headers must now be named
401 by using `silc' prefix, example: silcapi.h, silccipher.h.
402 Some files were renamed due to this. All the other headers
403 must not be used as public interfaces. I will update the
404 CodingStyle document later. Changed following headers, so far:
406 lib/silcclient/silcapi.h
407 lib/silccore/silcauth.h
408 lib/silccore/silcprivate.h
409 lib/silccrypt/silcdh.h
411 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
415 * Removed silc_client_packet_send_flush from the client library
416 as it is not needed. Affected file lib/silcclient/client.[ch].
418 * Added printing of message of unresolved authentication method
419 to the Irssi SILC client. Added it to the module formats.
420 Removed the same message from the client library.
422 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
424 * Added new distribution feature, DISTLABEL. Every distribution
425 can define own preprocessor label that can be used in the
426 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
427 file distributions, acconfig.h.pre and prepare.
429 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
431 * Added Makefile.defines_int to include the actual definitions
432 for Makefile.defines.in. Tested the new distribution system,
433 created distributions and tested installation.
435 * Added AWAY message printing to the Irssi SILC client. Added
436 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
438 * Added SCONNECT command to call the SILC's CONNECT command.
439 Cannot use CONNECT directly since Irssi uses that internally.
440 Affected file irssi/src/silc/core/silc-servers.c.
442 Added ACTION local command. It is same as ME command but takes
443 the channel as mandatory argument.
445 Rewrote some of the Irssi's help files to suite for SILC
448 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Added Makefile.defines[.in] that should for now on be included
451 in all Makefile.am file in the source tree. That file includes
452 all common compilation definitions for SILC source tree.
454 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Minor changes to the ./prepare script to change the package
457 name according the distribution name to the configure.in.
459 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
461 * Created new distribution system. Added file `distributions'
462 that defines all the distributions that can be created out of
463 the SILC source tree. The ./prepare script now reads that
464 file to determine how to prepare the distributions. The
465 first argument to the ./prepare is the name of the distribution
466 and second is the version of the distribution. If given
467 without arguments it creates the default (toolkit) distribution
468 with the default version (defined in ./prepare).
470 All Makefile.am files that are subject to the distributions
471 are now named as Makefile.am.pre. These are ./Makefile.am
472 and lib/Makefile.am. Others may be changed later.
474 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
476 * Added invite list, ban list, some key management and connection
477 error message printing to module formats in the Irssi SILC client.
479 * Added new silc_client_set_away_message to set the away message
480 that is back to the person who sent private message. The
481 affected file lib/silcclient/silcapi.h and the
482 lib/silcclient/client_prvmsg.c.
484 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Fixed the private message sending in the Irssi SILC client,
487 added local command KEY to the Irssi SILC client.
489 Added key management and key agreement message formats to the
490 irssi/src/fe-common/silc/module-formats.[ch].
492 Added USERS (alias WHO) printing, server/router operator
493 indication and LIST command printing to the module formats.
495 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
497 * Fixed channel joining notify handling, cumode notify handling
498 from Irssi SILC client.
500 * Added SILC specific module-formats to the Irssi SILC client so
501 that SILC specific message hilighting, colors etc is possible.
502 Affected file irssi/src/fe-common/silc/module-formats.[ch].
504 Added channel mode, channel user mode, actions, notices,
505 whois and whowas printing to the the module-formats.c.
507 * Fixed a bug in channel deletion in the server. The channel
508 is not left to the cache even if the channel founder auth mode
509 is set when there are no users anymore on the channel. Affected
512 * The silc_net_localhost now resolves the entire hostname including
513 the domain name. Affected file lib/silcutil/silcnet.c.
515 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
517 * Changed the ask_passphrase client operation to be ascynchronous.
518 It has now a completion callback and a context that the
519 application must call after it has got the passphrase from
520 the user. Affected files lib/silcclient/silcapi.h,
521 lib/silcclient/protocol.c, lib/silcclient/command.c and
524 Added SilcAskPassphrase callback that the application calls
525 to deliver the passphrase to the library.
527 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
528 The public key verification and especially a certificate
529 verification is asynchronous procedure.
531 Added new SILC_SKE_STATUS_PENDING status to indicate the
532 request is pending and a callback will be called to finalize
535 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
536 indicate that remote end did not send its public key (or
537 certificate), even though we require it. Added check for this
538 condition in the SKE. This was a security bug, now fixed.
540 Defined new SilcSKEVerifyCbCompletion callback that is called
541 when the verification process is completed.
543 The affected files lib/silcske/silcske_status.h and
544 lib/silcske/silcske.[ch].
546 * Changed the verify_public_key client operation to be async
547 as well. Defined SilcVerifyPublicKey callback that is used to
548 indicate the success of the public key verification process.
550 Changed the server and client to use the new async client
553 * Changed the Irssi SILC client's internal scheduler to be called
554 twice as many times as it used to be. As a result the client
555 should be a bit faster now. Affected file is
556 irssi/src/silc/core/silc-core.c.
558 * Added support to Irssi SILC client of asynchronous public key
559 verification and passphrase inquiry. Affected file is
560 irssi/src/silc/core/silc-core.c.
562 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
564 * Do not say "You have left channel %s" in client library.
565 Moved it to the application. Affected files are
566 lib/silcclient/command.c and silc/client_ops.c.
568 * Fixed silc_client_get_clients. Command context was not
569 duplicated and was freed memory in the callback. Affected
570 file lib/silcclient/idlist.c.
572 * Do not say "you are now talking..." on JOIN command in the
573 client library. The appliation must handle it.
575 * Do not say ".. changed topic to" in command reply in the
576 client libary. The application must handle it.
578 * Fixed TOPIC command sending in the client library.
580 * Fixed a memory leak in silc_client_command_free in the file
581 lib/silcclient/command.c.
583 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
585 * Imported a modified version of Irssi client to the source tree.
586 The Irssi will be used to create a new client called
587 Irssi SILC. Imported to irssi/.
589 Added silc_core_init_finish function to the Irssi. Affected
590 file irssi/configure.in.
592 A lot changes in the Makefile.ams around the irssi tree.
594 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
596 * Do not rehash if the new size is same as the old size of the
597 hash table, in the silc_hash_table_rehash*. The affected file
598 lib/silcutil/silchashtable.c.
600 * Replaced hash_table_del_by_context calls from the server
601 (when channel->user_list and client->channels) to the
602 hash_table_del as it is sufficient and faster.
604 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
606 * Added silc_hash_table_list, silc_hash_table_get and the
607 SilcHashTableList structure to provide an alternative way to
608 traverse the hash table. The affected files are
609 lib/silcutil/silchashtable.[ch].
611 * Changed the server's idlist routines to use the hash table
612 routines to optimize the code.
614 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
616 * Replaced the client entry's `channel' list and channel entry's
617 `user_list' list to hash tables for optimized lookup. Changed
618 the code to use the hash table interface around the code.
619 Affected file lib/silcd/idlist.[ch].
621 * Added `auto_rehash' boolean argument to the function
622 silc_hash_table_alloc to indicate whether the hash table should
623 auto-rehash when it thinks is appropriate time. It will
624 increase the hash table size if the there is twice as much
625 entries in the table than the size of the table, and will
626 decrease the size if there are twice as less entries than
627 the size of the table.
629 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Fixed silc_xxx_get_supported to not crash at some circumstances.
633 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
635 * silc_idcache_purge_by_context deletes the entry now by context
636 as it is supposed to do. Affected file lib/silccore/idcache.c.
638 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
639 client is not anymore valid (WHOWAS givens the info) and not
640 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
642 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
644 * Removed the `data' and `data_len' arguments from the ID Cache
645 interfaces and added `name' argument. ID Cache does not handle
646 anymore the binary data only a names associated with given ID.
648 * When hashing a Client ID with silc_hash_id the entire ID is
649 not hashed anymore, instead only the hash of the Client ID is
650 hashed. This way we can access the Client ID from the cache
651 with Client ID but with the hash of the ID (which is a hash of
652 the nickname) as well without any difference in performance.
654 Added also silc_idcache_find_by_id_one_ext to do one on one
655 searching when we have the actual ID. Added also function
656 silc_hash_client_id_compare. The affected files are
657 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
659 * When hashing the name associated with a ID it is always done
660 in lowercase. This way we can access the cache without worrying
661 about case-sensitivity, even though, for example nicknames are
664 * Fixed a bug in server with channel message sending. It put
665 wrong ID type as destination ID. The affected file
668 * silc_idcache_del_by_context now deletes from all hash tables
669 by context. Affected file lib/silccore/idcache.c.
671 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
673 * Changed the client library to use the new ID Cache interface.
674 Changes around the source tree.
676 * Added silc_hash_table_rehash_ext to rehash with specific
677 hash function. Affected file lib/silcutil/silchashtable.[ch].
679 * Added silc_hash_string_compare to compare two strings in the
680 hash table. Affected file lib/silcutil/silcutil.[ch].
682 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
684 * Added new function silc_idcache_del_by_context into the
685 lib/silccore/idcache.[ch].
687 * Changed the server's ID list routines to use the new ID Cache
688 interface. Changes around the source tree.
690 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * Added silc_hash_table_del[_by_context]_ext functions in to the
693 lib/silcutil/silchashtable.[ch].
695 Removed silc_hash_table_find_all* routines and added new
696 silc_hash_table_find_foreach to replace them.
698 Added silc_hash_table_replace_ext function as extended
699 replacing function. Separated the simple hash table interface
700 from the extended hash table interface in the file
701 lib/silcutil/silchashtable.h.
703 * Fixed minor bugs and changed it to use some of the new
704 hash table functions in lib/silccore/idcache.c
706 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
708 * Added new function silc_hash_table_find_all to return all keys
709 in the hash table by the specified key. As the hash table is
710 collision resistant it also makes it possible to have several
711 duplicate keys in the hash table. This function may be used to
712 find all of the keys from the hash.
714 Added user_context arguments to the SilcHashFunction,
715 SilcHashCompare and SilcHashDestructor to deliver user specified
718 Added new fuctions silc_hash_table_find[_all]_ext to do
719 extended lookup with specified hash and compare functions and
720 specified user contexts.
722 Added new function silc_hash_table_add_ext to add the key
723 with specified hash function and user context.
725 Added new function silc_hash_table_foreach to traverse all
726 entrys in the hash table. Added SilcHashForeach callback
729 Added new function silc_hash_table_del_by_context to delete
730 the entry only if the context associated with the key matches.
732 Affected files are lib/silcutil/silchashtable.[ch].
734 * Removed silc_hash_[server/client/channel]_id and added just
735 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
736 silc_hash_id_compare to compare two ID's using as the hash table
737 comparison function. Added also silc_hash_data to hash
738 binary data and silc_hash_data_compare to compare it.
740 * Removed silc_idlist_find_client_by_hash as it is not needed
741 anymore. Affected file silcd/idlist.[ch].
743 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
744 to use internally the SilcHashTable. The new ID Cache is a lot
745 faster than the old one. Some of the ID Cache interface was also
746 rewritten and obsolete and stupid functions were removed.
748 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
750 * Added entry_count field to the SilcHashTable to keep the number
751 of the entries in the table. Implemented the function
752 silc_hash_table_rehash. Added new function
753 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
755 Fixed a minor bug in silc_hash_table_free.
757 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
758 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
759 into the lib/silcutil/silcutil.[ch].
761 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
763 * Implemented a collision resistant hash table into the
764 lib/silcutil/silchashtable[ch]. See the header and the source
765 for the SilcHashTable API.
767 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
769 * Merged dotconf version 1.0.2 into lib/dotconf.
771 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
773 * Do not compile anything in lib/silcsim/* if the SIM support
774 is not enabled. The tree should now compile without problems
777 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Compiled the SILC under cygwin. Compiled and tested briefly
780 without problems. More tests needed. The SIMs didn't compile
783 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
785 * Fixed possible crash in silc_get_username in the
786 lib/silcutil/silcutil.c.
788 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
790 * Fixed a va_arg in silc/client_ops.c.
792 * Oops, RC5 routines were named AES and caused some problems
793 when not using SIM's. Affected file lib/silccrypt/rc5.c.
795 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Added new SilcIDIP structure into the lib/silccore/id.h and
798 replaced the old `ip' fields from all SILC ID's to that type.
799 This is a step towards IPv6 support.
801 The silc_id_get_len takes now the ID as an extra argument.
802 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
803 both IPv4 and IPv6 based ID's.
805 The affected files are lib/silccore/id.[ch] and other files
806 around the tree using these routines.
808 * Removed the ID length arguments in server from various
809 silc_server_send_notify_* routines -> they are not needed
812 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
814 * Fixed memory leak in silc_encode_pem_file in the file
815 lib/silcutil/silcutil.c.
817 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
819 * Check minor version as well in the SKE. Affected files are
820 silcd/protocol.c and lib/silcclient/protocol.c.
822 * Added --identifier option to the server so that an identifier
823 can be when creating the public key for the server. Affected
824 file is silcd/silcd.c.
826 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
827 lib/silccrypt/silcpkcs.c.
829 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
831 * Register default ciphers and stuff when using -C option with
832 the server. Affected file sildc/silcd.c.
834 * Put back the servers public key filename format, it is better
835 than the new one. For now, the client keys are saved with the
836 new filename format. The affected file silc/client_ops.c.
838 * Implemented the Cipher API for the rest of the ciphers that
839 did not implement it or implemented it the wrong way.
841 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
843 * Register default ciphers and stuff when using the -S option
844 in the client. Affected file silc/silc.c. Same also when
845 creating new key pair with -C option.
847 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
849 * Fixed the silc_verify_public_key client operation function to
850 save the public keys differently. The fingerprint is now
851 used as filename and not the hostname. This way also the
852 client keys are saved uniquely and not with hostnames. The
853 affected file is silc/client_ops.c.
855 * Trimmed the silc_hash_fingerprint function to remove extra
856 whitespaces from the end of the fingerprint. The affected
857 file is lib/silccrypt/silchash.c.
861 * Added silc_cipher_register_default function to register all
862 default ciphers. It can be used when configuration files
863 does not exist and the application does not want any specific
864 ciphers in any specific order.
866 The SilcDList is now used as silc_cipher_list dynamically
867 allocated cipher list. Removed the static list all together
868 and now all ciphers must be allocated to the dynamic list.
869 The silc_cipher_alloc routine was changed to check only the
872 All silc_cipher_* routines that used to return int returns
875 The affected files lib/silccrypt/silccrypt.[ch].
877 * The same thing was done to silc_hash_* as for silc_cipher_*
878 routines. Affected files lib/silccrypt/silchash.[ch].
880 * The same thing was done to silc_pkcs_* as for silc_cipher_*
881 routines. Affected files lib/silccrypt/silcpkcs.[ch].
882 Added also silc_pkcs_[un]register[_default] functions.
883 Removed the data_context from the PKCS API.
885 * Added silc_hmac_register_default function to register default
886 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
887 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
888 to unregister all hmacs at once.
890 * Register the default ciphers, hash functions, PKCSs and HMACs
891 if client's configuration file does not exist. The affected
894 * The client did not load the hash functions from the SIM
895 modules at all. Added support for this. Affected file is
898 * When decoding public key with silc_pkcs_public_key_decode, check
899 the supported algorithm only if PKCS are registered. Affected
900 file lib/silccrypt/silcpkcs.c. The same was done with the
901 silc_pkcs_private_key_decode.
903 * Fixed the SILC List routines to keep the list always in order.
904 It used to change the list's order when traversing the list but
905 not it preserves the order. Affected file lib/trq/silclist.h.
907 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * Added the client library to use the SilcSocketConnection's
910 reference counter (by silc_socket_dup) to prevent the bug that
911 the socket object may be freed underneath async operation.
913 * The name resolv library checking fixes in the configure.in.pre.
916 * Created new version of the protocol drafts for future
917 development. The -03 drafts are the ones that will be changed
918 in the trunk now and the -02 will remain as they are.
920 * Send list of CUMODE notifys to the router when announcing
921 the channel users to the router. Affected file silcd/server.c.
922 If the router receiving channel founder CUMODE for a channel
923 that already has channel founder it will send CUMODE notify
924 to the sender to remove the channel founder rights from the
925 announced client. Affected file silcd/packet_receive.c.
927 * The CUMODE notify may now use Server ID as well as the entity
928 who changes the mode. Updated protocool specs.
930 * Updated INSTALL and README files.
932 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
934 * New web pages in the http://silc.pspt.fi. The pages was
939 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
941 * Implemented the [DenyConnectin] config section in the server.
942 Added silc_server_config_denied_conn to check whether incoming
943 connection is denied. Affected file silcd/serverconfig.[ch].
945 * Do not check the ports when checking the incoming configuration
946 data if the port is 0, meaning any. Affected file is
947 silcd/serverconfig.c.
949 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
951 * Fixed buffer overflow in silc_string_compare in the file
952 lib/silcutil/silcutil.c.
954 * Fixed double free in silc_server_command_leave in the file
957 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
959 * Fixed the version checking in the server. Affected file is
962 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
964 * Fixed the configuration data fetching when accepting new
965 connections in the server. Affected file silcd/server.c.
967 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Added `sender_entry' argument to the function
970 silc_server_packet_relay_to_channel so that we can check
971 whether some destination actually belongs to the same route
972 the sender belongs (ie, we must not resend the packet to the
973 sender). Affected file silcd/packet_send.[ch].
975 * Added `servername' field to the SilcClientEntry in the server
976 to hold the name of the server where client is from. Affected
977 file is silcd/idlist.h.
979 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
981 * Moved the channel message encrypting in the router betwen
982 router connections from silc_server_channel_message to the
983 silc_server_packet_relay_to_channel since we want to check
984 whether we have anybody channel before encrypting anything.
985 Affected files silcd/packet_[receive/send].c.
987 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
989 * Fixed the [AdminConnection] server config section to support
990 multiple entries. Affected file silcd/serverconfig.c.
992 * Added support into the server to check the validity of the
993 incoming connection before executing any KE or authentication
996 * The connection configuration is now saved to the KE and
997 connection auth protocol contexts and not fetched anymore in
998 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1000 * The local hosts listenning address and port is also resolved
1001 now when starting the server. We want to have the socket object
1002 to include the real address and port for the listener. Added
1003 new function silc_net_check_local_by_sock into the files
1004 lib/silcutil/silcnet.[ch].
1006 * Fixed a broadcast bug in server -> do not broadcast if we
1009 * Fixed a routing bug. Do not route broadcast packets ever.
1010 Broadcast packets must be processed always and not routed since
1011 they may be destined to some other host than yourself and thus
1012 would get routed without no good reason. Affected file is
1015 * Added function silc_server_config_is_primary_route to check
1016 whether primary router connection has been configured (a router
1017 configuration that we are initiating). If there is not, we
1018 will assume that there is only two routers in the SILC network
1019 and we will use the incoming router connection as our primary
1020 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1022 * Changed the order of the broadcasting. Broadcast _after_ the
1023 packet has been processed not before. Affected file is
1026 * Fixed a [ClientConnection] parsing bug. The port was never
1027 parsed correctly thus resulting to port 0. Affected file
1028 silcd/serverconfig.c.
1030 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1031 argument and did not set the broadcast packet flag. Affected
1032 file silcd/packet_send.c. Fixed same bug in the function
1033 silc_server_send_notify as well.
1035 * If we receive NEW_ID packet for our own ID in the server, ignore
1038 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1042 * Removed the nickname from the Private Message Payload.
1043 Updated the code and the protocol specs.
1045 * Updated protocol specs for submitting to the IETF.
1047 * Tweaked the Random Number Generator a bit. Affected file
1048 lib/silccrypt/silcrng.c. Exported a new function
1049 silc_rng_[global]_add_noise which can be used to add more
1052 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Do not parse packets with different timeout when protocol
1055 is active -> may cause problem with rekey. Affected file
1058 * When server receives signoff notify it must not create
1059 new channel key if the client is on any channels since the
1060 sender of the signoff notify will create it.
1062 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1064 * Added printing of error messages during SKE protocol from the
1065 failure packet sent by server during SKE. Affected file
1068 * Removed the client's failure_callback handling with timeout
1069 and handle it immediately when received.
1071 * The SKE library returned wrong type in SUCCESS and FAILURE
1072 packets. They must be 32 bit MSB not 16 bit MSB.
1074 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Ok, rewrote the logic of the re-key and now it seems to work.
1077 I tested it on high traffic with frequent re-keys without
1078 problems. Added hmac_receive (and renamed hmac to hmac_send)
1079 in SilcClientConnection in lib/silcclient/client.h and
1080 in SilcIDListData in silcd/idlist.h. Also, removed the
1081 SilcPacketParserContext's cipher and hmac fields as they are
1082 not needed anymore and actually caused some problems when
1083 the ciphers and hmac's changed underneath the packet parser.
1085 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * If re-key protocol is active then process the incoming packets
1088 synchronously since we must assure that icoming packets encrypted
1089 with the old key is processed before the new keys is set to
1090 use. This is true other packets than for REKEY packets.
1091 Affected file silcd/server.c. The same was done to client library
1092 as well, affected file lib/silcclient/client.c.
1094 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * Fixed bug in client and server to accept the force send if
1097 the packet is send from silc_[server/client]_packet_process
1098 function. Otherwise the packets are never delivered, oops.
1100 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1102 * Disable force sending of packets when REKEY protocol is active.
1103 We must assure that no packet is sent directly when rekey is
1104 performed. All packets must be sent through packet queue.
1105 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1106 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1107 function is silc_[server/client]_packet_send_real to check
1110 * Replaced the SIM paths from example config files to
1111 /usr/local/modules. Also, make install creates now
1112 /usr/local/silc/logs directory to hold all the SILC server
1115 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

1126 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * When MAC computation fails the silc_packet_decrypt returned 0
1129 even though it was supposed to return -1. Fixed this. The
1130 affected file is lib/silccore/silcpacket.c.
1132 * Do not replace the config files in /etc/silc (in make install)
1133 if they already exist. Affected file ./Makefile.am.
1135 * Do not send re-key packets immediately but through packet queue.
1136 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1138 * Changed silc_net_check_host_by_sock to return FALSE if the
1139 IP/DNS could not be resolved. Though, it returns the IP address
1140 now even if it could not resolve it (but returns also FALSE).
1141 Affected file lib/silcutil/silcnet.[ch].
1143 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1145 * Added silc_pkcs_decode_identifier to decode the public key's

1147 Added also silc_pkcs_free_identifier. Added also new context
1148 SilcPublicKeyIdentifier.
1150 * Added -S option to the silc client. It is used to dump the
1151 contents of the specified public key file.
1153 * Changed the PKCS api to return the public key length when
1154 setting the public key.
1156 * Fixed a fatal bug in the public and private key file loading.
1157 Affected file lib/silccrypt/silcpkcs.c.
1159 * Execute the packet parsing for client with zero (0) timeout
1160 if the protocol is active. Affected file silcd/server.c.
1162 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * Made the key generation options to the silcd program. Added
1165 -C option, equivalent to client's option.
1167 * Added new [ServerKeys] config section to the server. It
1168 configures the server's public and private key.
1170 * Defined generic Public Key Payload into the protocol
1171 specification to send specific type of public keys and
1174 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1175 public key or certificate.
1177 * Implemented the GETKEY command to the server and to the
1178 client library and on user interface.
1180 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Made preliminary `make install' work.
1184 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * Added SilcServerRekey context into silcd/idlist.h.
1188 * Added the PFS support as defined in the specification to the
1189 SKE protocol. Affected files lib/silcske/*.c.
1191 * Added `ske_group' field to the SilcServerRekey context to hold
1192 the number of the SKE group that is used with PFS in re-key.
1193 Affected file silcd/idlist.h.
1195 * Added PFS re-key support to the server. Affected file is
1198 * Added silc_protocol_cancel to cancel execution of the next
1199 state of the protocol. Affected file is
1200 lib/silccore/silcprotocol.[ch].
1202 * Added the re-key support with and without PFS to the client
1203 library. Re-key is performed once in an hour, by default.
1205 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1206 Added silc_client_rekey_callback and silc_client_rekey_final.
1207 Affected files are lib/silcclient/protocol.[ch] and
1208 lib/silcclient/client.[ch].
1210 * Removed the `hmac_key' and `hmac_key_len' fields from the
1211 SilcClientConnection structure; not needed. Affected file is
1212 lib/silcclient/client.h.
1216 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Do not ask whether user wants to use the negotiated private key
1219 for private messages, just use it. Affected file is
1220 silc/local_command.c.
1222 * Added `send_enc_key' and `enc_key_len' fields to the
1223 SilcIDListData structure since they are needed in the re-key
1224 phase. Affected file is silcd/idlist.[ch].
1226 * Implemented the simple re-key protocol into the server.
1227 Affected files silcd/server.c and silcd/protocol.[ch]. The
1228 re-key will be performed once in an hour, by default.
1230 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1231 Added silc_server_rekey, silc_server_rekey_callback and
1232 silc_server_rekey_final.
1234 * Removed Tunneled flag from the protocol. Updated the code
1235 and the specifications.
1237 * Adde `pfs' field to the SilcIDListData to indicate whether
1238 the PFS is to be performed in the re-key. Affected file is
1241 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1243 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1244 int64 of at least the xintXX size. If void * is less that 4
1245 bytes uint32 * will be used. Defined bool as boolean.
1247 * Changed _ALL_ unsigned long and unsigned int to uint32,
1248 unsgined short to uint16 in the source tree.
1250 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1251 not handle clients that has entry->data.registered == FALSE.
1252 They are not in the network anymore. Affected file is
1255 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1257 * Implemented the sending of the SERVER_SIGNOFF notify in the
1258 server. Affected file is silcd/server.c.
1260 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1261 Added also silc_notify_payload_encode_args into the
1262 lib/silccore/silcnotify.[ch].
1264 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1265 Affected file silcd/packet_receive.c.
1267 * Implemented the SERVER_SIGNOFF notify handling in the client
1268 library. Affected file lib/silcclient/client_notify.c. Also,
1269 implemnted the printing of the SERVER_SIGNOFF info to the
1270 application. Affected file silc/client_ops.c.
1272 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1273 if the deleting was successful. Affected file silcd/idlist.[ch].
1275 * Added support for public key authentication in the connection
1276 authentication protocol in the client library. Affected file
1277 lib/silcclient/protocol.c.
1279 * Changed the server's silc_idlist_get_clients_by_* interface
1280 to support already allocated array so that new entries may be
1281 added to pre-allocated array. Affected file silcd/idlist.[ch].
1282 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1283 and command replies.
1285 * All command reply functions in the server now calls the
1286 pending command callback even if error occured. This way the
1287 error will be delivered to the client as well. Affected files
1288 silcd/command.c and silcd/command_reply.c.
1290 * Fixed INFO command to return local server's info if no server
1291 was provided. Affected file lib/silcclient/command.c.
1293 * Removed RESTART command for good. Updated the code and the
1296 * Rewrote parts of the task system. It is a bit simpler now.
1297 Removed unsued task priorities. The affected files are
1298 lib/silcutil/silctask.[ch].
1300 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1302 * Moved the USERS printing from the library to the application.
1303 Affected files lib/silcclient/command.c and silc/client_ops.c.
1305 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1309 * Added channel key re-key support. The re-key is perfomed
1310 only by the router and is done once in an hour. Added `rekey'
1311 field to the SilcChannelEntry in the server. Affected files
1312 silcd/server.c and silcd/idlist.h.
1314 * Added silc_task_unregister_by_context into the file
1315 lib/silcutil/silctask.[ch].
1317 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Added SILC_UMODE_GONE mode to indicate when the client is not
1320 present in the SILC network. Added also support to the local
1321 command AWAY that will set this mode. Added support of showing
1322 "xxx is gone" in WHOIS command. The USERS command shows the
1323 gone status as well.
1325 * Fixed setting server and router operator privileges in the
1326 server's UMODE command. Affected file silcd/command.c.
1328 * Merged the SKE KE1 and KE2 payloads into one payload. The
1329 new KE payload is equivalent to the old KE2 payload.
1331 Cleaned up the SKE Start Payload parsing. It now uses the
1332 simple buffer unformatting to do the parsing. A lot faster
1335 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1336 to the SKE that is used to indicate whether both of the SKE
1337 parties should perform authentication. By default only the
1338 responder performs authentication. By setting this flag also
1339 the initiator must do authentication. By default it is unset
1340 since in normal SKE case, client to server connection, only
1341 the responder should do authentication. When doing SKE between
1342 two clients both should perform authentication. Updated the
1343 code and the protocol specs.
1345 * A little fix to IDENTIFY command in the server. Search the
1346 client first by hash not nickname. Affected file is
1349 * Fixed the silc_client_close_connection to support closing
1350 the client to client connections wihtout deleting too much
1351 data. Affected file lib/silcclient/client.c.
1353 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1354 are received if protocol used to be active but is not anymore
1355 the application would crash due to NULL pointer dereference.
1356 Affected files silcd/server.c and lib/silcclient/client.c.
1358 * Added `hash' field to the SilcClientConnection to include
1359 the hash function negotiated in the SKE protocol.
1361 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1362 to set the channel founder authentication data. A client can
1363 claim the founder rights later by providing the authentication
1364 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1365 This way the channel founder can regain the channel founder
1366 privileges even it is left the channel. This works only on
1367 local server and the client must be connected to the same
1368 server to be able to regain the founder rights. Updated the
1369 protocol specs accordingly.
1371 Added support to the CMODE command in the client to set the
1372 founder auth data. Read the README to see how to set it.
1374 Added support to the CUMODE command to claim the founder
1375 rights. Read the README to see how to do it.
1377 Added support for the founder authentication to the Channel
1378 Entry in the server. Affected file silcd/idlist.h.
1380 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1381 server's CMODE command. Affected file silcd/command.c.
1383 * Added the following new functions into lib/silccore/silcauth.[ch]:
1384 silc_auth_get_method and silc_auth_get_data.
1386 * The server now saves the remote hosts public key to the
1387 SilcIDListData pointer. Affected file silcd/protocol.c.
1389 * The normal server now does not remove the channel entry from
1390 the cache if the founder authentication data is set. It used
1391 to remove it if the founder was the last one on the channel on
1392 the server and left the channel. The auth data is saved and
1393 if the channel is re-joined later the old entry is used with
1394 the old auth data. Affected files silcd/command_reply.c and
1397 * Removed the `pkcs' field from the SilcIDListData structure
1398 in the server; it is not used. Affected file silcd/idlist.h.
1400 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Fixed packet processing on slow links. Partial packets were
1403 never re-processed because the incoming data buffer was cleared
1404 by the application. Application must not directly clear the
1405 sock->inbuf, the packet processing routines handle it. Fixed
1406 this in client library and in server.
1408 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1410 * Fixed the WHOIS and IDENTIFY send reply function to really
1411 check whether to send list or just one entry. Affected file
1414 * Cleaned up the LEAVE command's channel key distribution. The
1415 affected file silcd/command.c.
1417 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1418 can enforce the channel mode as well. In that case the ID
1419 includes the ID of the server. The code now enforces the
1420 mode change if the router have different mode than the server.
1422 * The notify client operation with CMODE_CHANGE notify can now
1423 return NULL client_entry pointer if the CMODE was not changed
1424 by client. Application must check for this.
1426 * Added <Server ID> argument to INFO command to support server
1427 info fetching by Server ID.
1429 * Added silc_server_announce_get_channel_users to get assembled
1430 packets of channel users of the specified channel. Affected
1431 file silcd/server.[ch].
1433 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1434 was freed underneath the ID Cache.
1436 * Re-announce clients when the server received CHANNEL_CHANGE
1437 notify from the router. Affected file silcd/packet_send.c.
1439 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1441 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1442 crashed since it did not handle the fact that there is no cipher
1443 called "3" and didn't check the error condition. Now fixed.
1445 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1446 flag. It can be used to send message requests.
1448 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Implemented the RESTART command in the client.
1452 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1453 notice type messages. Added notice printing to the user
1456 * The channel keys are not re-generated if the channel's mode
1457 is PRIVKEY, ie private key on the channel exists. Affected
1458 files silcd/server.c and silcd/command.c.
1460 * Fixed a little bug in channel message delivery when channel
1461 private keys are set in the server. Affected file is
1462 silcd/packet_send.c.
1464 * Changed the setting on channel->on_channel = TRUE from the
1465 silc_client_save_channel_key to the JOIN command reply. The
1466 key payload is not received if the private channel key is set.
1467 Affected file lib/silcclient/command_reply.c and the
1468 lib/silcclient/client_channel.c.
1470 * When the CMODE_CHANGE notify is sent and the channel private
1471 key mode is removed the channel key must be re-generated in
1472 other cells as well. Added this support for the router in the
1473 silcd/packet_receive.c.
1475 * Added new local command NOTICE to send notice message on
1476 channel. Affected file silc/local_command.[ch].
1478 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1480 * Added new local command ME to the client. It is used to send
1481 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1482 some action. Affected file silc/local_command.[ch].
1484 * Changed channel_message and private_message client operations
1485 to deliver the message flags to the application. Added also
1486 the `flags' arguments to the silc_client_send_channel_message
1487 and silc_client_send_private_message functions. Affected file
1490 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1492 * Redefined the Private Message Payload to support private message
1493 keys and to support the new private message flags. Updated
1494 the protocol specs. Flags makes it possible to have for example
1495 CTCP style messages.
1497 * Added new type SilcPrivateMessagePayload and defined an API
1498 for it in the lib/silcclient/silcprivate.[ch].
1500 * Tested private message private keys successfully. Tested the
1501 private message key set, unset and list commands with the new
1504 * Redefined the Channel Message Payload to include the channel
1505 message flags (equal with private message flags) to support
1506 for example CTCP style messages.
1508 * Defined some of the message (for channel and private message)
1509 flags. Updated the protocol specs and added the flags to the
1510 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1512 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1514 * Added SilcKeyAgreementStatus type to the key agreement routines
1515 to indicate the current status and error if one occured.
1516 The status types are defined in the lib/silcclient/silcapi.h.
1518 * Added new local command KEY that is used to set and unset private
1519 keys for channels, set and unset private keys for private messages
1520 with remote clients and to send key agreement requests and
1521 negotiate the key agreement protocol with remote client. The
1522 key agreement is supported only to negotiate private message keys,
1523 it currently cannot be used to negotiate private keys for channels,
1524 as it is not convenient for that purpose.
1526 * Fixed a minor pending callback setting bug in the function
1527 silc_client_get_client_by_id_resolve, now the function works.
1528 Affected file lib/silcclient/idlist.c.
1530 * Added function silc_net_get_local_port to get local bound
1531 port by socket. Added to lib/silcutil/silcnet.[ch].
1533 * Added `sockets' and `sockets_count' fields to the SilcClient
1534 object. They hold the sockets of the listenning sockets in
1535 the client. Listenning sockets may be for example the key
1536 agreement server. Affected file lib/silcclient/client.[ch].
1537 Added functions the silc_client_add_socket and the
1538 silc_client_del_socket. They are exported to the application
1541 * Added ~./silc/clientkeys to support other client's public keys.
1543 * Renamed verify_server_key client operation to verify_public_key
1544 and added one argument to indicate the type of the connection
1545 (server, client etc.).
1547 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1549 * Added silc_server_connection_auth_request to handle the
1550 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1551 silcd/packet_receive.[ch].
1553 * Added silc_server_send_connection_auth_request into the
1554 silcd/packet_send.c to send the connection auth request packet.
1556 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1559 * Fixed the public key authentication in responder side in the
1560 server. The `auth_data' pointer includes the SilcPublicKey
1561 not the path to the public key. Affected file silcd/protocol.c.
1563 * Implemented the public key authentication in the initiator side
1564 in the server. Affected file silcd/protocol.c.
1566 * Removed the [RedirectClient] config section from the server
1567 configuration. Is not needed and I don't want to implement it.
1569 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Cleaned up the CMODE command in the server. It now works
1572 correctly and supports all the modes defined in the protocol.
1573 Affected file is silcd/command.c.
1575 * Added `hmac_name' field to the SilcChannelEntry in the server
1576 to hold the default HMAC of the channel. It can be set when
1577 creating the channel (with JOIN command). Affected files
1580 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1581 type to indicate the change of the current cipher and hmac
1582 on the channel. Client can safely ignore the <cipher> argument
1583 (if it chooses to do so) since the CHANNEL_KEY packet will
1584 force the channel key change anyway. The <hmac> argument is
1585 important since the client is responsible of setting the new
1586 HMAC and the hmac key into use.
1588 * Fixed the CMODE command in the client library as well.
1590 * Tested CMODE command in router environment successfully.
1592 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1594 * Show the version of the remote client (or server) when connecting
1595 to the server. It is logged to the log file. Affected file
1596 is silcd/protocol.c.
1598 * Fixed the KILLED notify handling in the client library. The
1599 client must be removed from all channels when receiving the
1602 Also, do not remove the client entry when giving the KILL
1603 command but when the KILLED notify is received.
1605 * Removed silc_idlist_find_client_by_nickname from the server.
1606 Not needed anymore. Affected files silcd/idlist.[ch].
1608 * Implemented the CHANNEL_CHANGE notify type handling to the
1609 server. Affected file silcd/server.c.
1613 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1615 * Added silc_server_send_notify_invite to send the INVITE
1616 notify between routers.
1618 * Implemented the INVITE command correctly to the server.
1620 * Implemented the INVITE notify type handling in the server.
1622 * Implemented the INVITE command to the client library and on the
1625 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1627 * Added function silc_server_get_client_resolve to find the
1628 client entry by ID from all ID lists and then resolve it
1629 (using WHOIS) if it cannot be found. Affected file is
1632 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1634 * Implemented the BAN command to the client library.
1636 * The JOIN command in the server now checks the invite list
1639 * Changed the silc_command_reply_payload_encode_va and the
1640 silc_command_payload_encode_va to support that if argument is
1641 NULL it ignores and checks the next argument. Affected file
1642 lib/silccore/silccommand.c.
1644 * Added silc_server_send_notify_ban to send the BAN notify
1645 type between routers.
1647 * Chaned the silc_notify_payload_encode to support that if
1648 argument is NULL it ignores and checks the next argument.
1649 Affected file lib/silccore/silcnotify.c.
1651 * Tested ban lists in router environment successfully.
1653 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Implemented BAN command to the server, in silcd/command.[ch].
1657 * Removed the BAN and INVITE_LIST modes from the CMODE command
1660 * Added function silc_string_match to regex match two strings.
1661 Affected files lib/silcutil/silcutil.[ch].
1663 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * Redefined parts of the SilcChannelEntry in the server to support
1666 the new ban and invite lists.
1668 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Redefined the INVITE command. The same command can be used to
1671 invite individuals to the channel but also to manage the invite
1672 list of the channel (to add to and remove from the invite list).
1673 Updated the protocol specs.
1675 * Added new command SILC_COMMAND_BAN that can be used to manage
1676 the ban list of the channel. Updated the protocol specs.
1678 * Removed the channel modes: the SILC_CMODE_BAN and the
1679 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1680 in the CMODE command. The equivalent features are now available
1681 using INVITE and BAN commands. Updated the protocol specs.
1683 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1684 in the network about change in the current ban list. The notify
1685 type is not used by the client.
1687 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1688 support the invite lists.
1690 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1692 * Added new function silc_string_regexify that converts string
1693 including wildcard characters into regex string that can
1694 be used by the GNU regex library. Added into the file
1695 lib/silcutil/silcutil.[ch].
1697 Added silc_string_regex_combine to combine to regex strings
1698 into one so that they can be used as one regex string by
1699 the GNU regex library. Added into the file
1700 lib/silcutil/silcutil.[ch].
1702 Added silc_string_regex_match to match two strings. It returns
1703 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1705 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1707 * Imported GNU regex to the soruce tree into lib/contrib.
1708 Fixed some compiler warning from the regex.c.
1710 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1712 * Fixed MOTD command in the server to work in router environment.
1714 * Fixed the MOTD command in the client library to support
1715 the server argument in the command.
1717 * Added `nickname_len' argument to the silc_idlist_add_client
1718 in the server, as the `nickname' argument may be binary data
1721 * Added silc_idlist_get_channels to return all channels from
1724 * Implemented LIST command to the server. Affected file is
1727 * Implemented the LIST command to the client library and on the
1730 * Added [<user count>] argument to the LIST command reply.
1731 With private channels the user count is not shown.
1733 * Updated TODO and README.
1735 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * The client entry's data.registered must be TRUE even with
1738 global client entry on global client list. The data.registered
1739 is used to check whether the client is anymore in the network,
1740 for example with WHOWAS command so it must be valid.
1742 * Fixed the WHOWAS command in the server. It now actually works
1743 in router environment. Added function into silcd/command_reply.c
1744 silc_server_command_reply_whowas_save.
1746 * Added silc_idlist_purge function to the silcd/idlist.c
1747 to periodically purge the ID Cache.
1749 * Fixed INFO command in the server. It works now in router
1750 environment. Added <server name> argument to the INFO command
1751 reply. Updated the protocol specs.
1753 * Fixed minor bug in silc_idcache_purge to not purge if the
1754 expire value is zero.
1756 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1757 they were buggy because of the WHOWAS information.
1759 * Fixed local command MSG to handle the async resolving of
1760 the remote client properly. It used to fail the first MSG.
1761 Affected file silc/local_command.c.
1763 * Added `data_len' field to SilcIDCache context.
1765 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1767 * Update TODO. Todo in commands in the server.
1769 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1771 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1772 used by routers as broadcast packet to inform other routers
1773 about the changed user mode.
1775 Implemented the notify handling in the server. Affected file is
1776 silcd/packet_receive.c. Added the function
1777 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1779 * Added new generic Channel Payload and deprecated the New Channel
1780 Payload. The New Channel Payload is now the generic Channel
1783 * Added new argument `mode' to the silc_server_send_new_channel
1784 as it is required in the Channel Payload now.
1786 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1787 and created a new and real SilChannelPayload to represent the
1788 new generic Channel Payload. Implemented the encode/decode
1789 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1791 * Added silc_server_get_client_channel_list to return the list
1792 of channels the client has joined for WHOIS command reply.
1793 Affected file silcd/server.[ch].
1795 * Implemented the channel list sending in the WHOIS command reply
1796 in server and in the client.
1798 Implemented the channel list displaying on the user interface
1799 as well. Affected file silc/client_ops.c.
1801 * Added silc_channel_payload_parse_list to parse list of Channel
1802 Payloads. It returns SilcDList list of SilcChannelPayloads.
1803 Client for example can use this function to parse the list of
1804 channels it receives in the WHOIS command reply. The caller
1805 must free the list by calling silc_channel_payload_list_free.
1806 Affected files lib/silccore/silcchannel.[ch].
1808 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * Added one new argument <user mode> to the WHOIS command reply
1811 to return the mode of the user in SILC. Updated the protocol
1814 Implemented it to the server and client.
1816 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Fixed the mode printing on the user interface on joining.
1819 Affected file silc/client_ops.c.
1821 * Implemented the UMODE command and user modes in general to the
1822 client library and to the user interface.
1824 * Implemented the UMODE command to the server.
1826 * The server now sends UNKNOWN_COMMAND error status if client sends
1827 unknown command. Affected file silcd/command.c.
1829 * All server commands now handle the command identifier the right
1830 way when sending the command reply to the client. The client can
1831 use to identify the command replies with the identifier.
1833 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1835 * Added silc_server_get_client_route to resolve the route to
1836 the client indicated by the client ID. Affected file is
1839 * Added silc_server_relay_packet as general function to relay
1840 packet to arbitrary destination. This deprecates functions
1841 like _send_private_message_key, _relay_notify etc. Affected
1842 file is silcd/packet_send.[ch].
1844 Removed silc_server_send_key_agreement,
1845 silc_server_send_private_message_key and
1846 silc_server_packet_relay_notify functions from the file
1847 silcd/packet_send.[ch].
1851 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1852 server. Affected file silcd/packet_receive.[ch].
1854 * Implemented the KILL command to the client. Implemented the
1855 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1856 Affected files lib/silcclient/command[_reply].c and
1857 lib/silcclient/client_notify.c. Implemented the KILL notify
1858 printing in the user inteface.
1860 * Fixed a lot silc_parse_nick memory leaks from the client
1861 library in the file lib/silcclient/command.c.
1863 * Changed the silc_server_send_notify_on_channels's `sender'
1864 argument from SilcSocketConnection to SilcClientEntry to
1865 check the sender as entry and not as connection object and not
1866 to send to the client provided as argument. The affected file
1867 is silcd/packet_send.[ch].
1869 * The notify packets that are destined directly to the client used
1870 to not to be processed by the server. Now changed that and the
1871 server processes all notify packets. After relaying the packet
1872 to the client the notify packet is processed in the server.
1874 * The silc_server_free_client_data now checks whether there is
1875 pending outgoing traffic for the client and purges the data to
1876 the network before removing the client entry.
1878 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1881 an client is killed from the SILC Network. Updated the protocol
1884 Added new function silc_server_send_notify_killed to the
1885 silcd/packet_send.[ch].
1887 * Added function silc_server_packet_relay_notify to relay notify
1888 packets that are destined directly to a client. In this case
1889 the server does not process the notify packets but merely relays
1890 it to the client. Affected file silcd/packet_send.[ch].
1892 Added also silc_server_packet_process_relay_notify to check
1893 whereto relay the notify. Affected file is
1894 silcd/packet_receive.[ch].
1896 * Implemented the KILL command to the server.
1900 * Added the backup schema desgined last fall to the protocol
1901 specs for everyone to see. The specification is in the
1902 *-spec-xx.txt draft and the packet type definitions for the
1903 backup routers is in *-pp-xx.txt draft. Thusly, added also
1904 new packet type SILC_PACKET_CELL_ROUTERS.
1906 * A big security problem in the implementation discovered. The
1907 signoff of an client did not cause new channel key generation
1908 which it of course should've done. The channel keys must be
1909 always re-generated when client leaves (or signoffs) the channel.
1910 The silc_server_remove_from_channels funtion now handles
1911 the channel key re-generation.
1913 * Added `sender' argument to the silc_server_send_notify_on_channels
1914 to not to send the client provided as argument. Affected file
1915 silcd/packet_send.[ch].
1917 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Implemented OPER and SILCOPER commands into the server and
1922 * Added silc_auth_verify and silc_auth_verify_data to verify
1923 the authentication directly from the authentication payload.
1924 It supports verifying both passphrase and public key based
1925 authentication. Affected file lib/silccore/silcauth.[ch].
1927 * Added `hash' field to the SilcIDListData structure. It is the
1928 hash negotiated in the SKE protocol. Affected file is
1931 * Slight redesigning of the SilcAuthPayload handling routines.
1932 Do not send SilcPKCS but SilcPublicKey as argument.
1934 * Implemented the public key authentication support to the
1935 serverconfig. The public key is loaded from the provided path
1936 and saved as authentication data to void * pointer. Thus,
1937 changed the unsigned char *auth_data to void *auth_data;
1939 * Fixed SHUTDOWN command to send the reply before the server
1940 is shutdown. :) Affected file silcd/command.c.
1942 * Fixed fatal bug in CONNECT command. The hostname was invalid
1943 memory and server crashed. Affected file silcd/command.c.
1945 * Fixed fatal bug in CLOSE command. The server_entry became
1946 invalid but was referenced later in the command. Affected file
1949 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1951 * Fixed fatal bug in failure packet handling. Server ignored
1952 the failure and thus crashed when it came.
1956 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1958 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1959 that the command may be executed only once in (about) 2 seconds.
1960 The old SILC_CF_LAG flag is same but allows command bursts up
1961 to five before limiting.
1963 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1964 server code. Various commands now includes the CF_LAG_STRICT
1965 flag to disallow any kind of miss-use of the command.
1967 * Fixed the silc_buffer_unformat to not to allocate any data
1968 if the length of the data is zero. It used to allocate the
1969 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1971 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1973 * Changed the format of AdminConnection configuration section
1974 in the server. Added username of the admin to the format.
1975 Affected files silcd/serverconfig.[ch].
1977 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1978 to return admin configuration data by host, username and/or
1981 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1983 * Implemented WHOWAS command to the server. Added the functions:
1985 silc_server_command_whowas_parse,
1986 silc_server_command_whowas_send_reply,
1987 silc_server_command_whowas_from_client and
1988 silc_server_command_whowas_from_server
1990 * Added <Client ID> argument to the WHOWAS command reply. Updated
1991 the protocol specs accordingly.
1993 * Implemented WHOWAS command and command_reply to the client
1996 Implemented the WHOWAS printing on the user interface.
1998 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2000 * Added new argument to the WHOWAS command reply, the real name.
2001 It is an optional argument. Updated the protocol specs.
2003 * Added SilcIDCacheDestructor callback that is registered when
2004 the SilcIDCache is allocated. The callback is called when
2005 an cache entry in the ID Cache expires, or is purged from the
2006 cache. Added into lib/silccore/idcache.[ch].
2008 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2009 to destruct the client entries when the cache entry expires.
2010 Other ID Cache's in server and in the client library ignores
2013 * If the ID Cache entry's `expire' field is zero then the entry
2014 never expires. Added boolean `expire' argument to the
2015 silc_idcache_add function in the lib/silccore/idcache.[ch].
2016 If it is TRUE the default expiry value is used.
2018 * Added silc_server_free_client_data_timeout that is registered
2019 when client disconnects. By default for 5 minutes we preserve
2020 the client entry for history - for WHOWAS command.
2022 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Added support to the server to enforce that commands are not
2025 executed more than once in 2 seconds. If server receives
2026 commands from client more frequently, timeout is registered
2027 to process the commands. Affected file silcd/command.c.
2028 Added new function silc_server_command_process_timeout.
2030 * Changed NICK_NOTIFY handling in client library to check that
2031 if the client's nickname was changed, so there is no need to
2032 resolve anything from the server.
2034 * Removed error printing from the WHOIS and IDENTIFY commands.
2035 If error occurs then it is ignored silently in the client library.
2036 The application, however, may map the received error to
2037 human readable error string. The application currently maps
2038 the NO_SUCH_NICKNAME error to string.
2040 * Made the command status message public to the application. Moved
2041 them from lib/silcclient/command_reply.c to
2042 lib/silcclient/command_reply.h. The application can map the
2043 received command status to the string with the
2044 silc_client_command_status_message function.
2046 * Added check to the server to check that client's ID is same
2047 as the Source ID in the packet the client sent. They must
2050 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2052 * Added dist-bzip hook to the Makefile.am to make bzip2
2053 compressed distributions.
2055 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2057 * Server now enforces the maximum length for the nickname and
2058 the channel as protocol specification dictates. 128 bytes for
2059 nickname and 256 bytes for channel name.
2061 * Moved the WHOIS printing to the application. The client libary
2062 does not print out the WHOIS information anymore, the application
2063 must do it. Renamed silc_client_command_reply_whois_print to
2064 the silc_client_command_reply_whois_save.
2066 The client's idle time is also sent to the application now, and
2067 the idle is shown on screen.
2069 * Added silc_client_command_reply_identify_save to save the
2070 received IDENTIFY entries.
2072 * Do not check for channel private keys in message sending and
2073 reception if the channel does not have the PRIVKEY mode set.
2074 Affected file lib/silclient/client_channel.c.
2076 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2078 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2079 just surfaced after chaning the JOIN procedure.
2081 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2083 * Added silc_client_get_clients_by_list to get client entries
2084 from Client ID list, that is returned for example by JOIN
2085 and USERS command replies. The application should use this
2086 function for example when JOIN command reply is received to
2087 resolve the clients already on the channel (library does not
2088 do that anymore as USERS command reply is not used in the JOIN
2089 procedure anymore). Affected files lib/silcclient/silcapi.h and
2090 lib/silcclient/idlist.c.
2092 * JOIN command reply and USERS command reply returns now SilcBuffer
2093 pointers instead of unsigned char pointers when returning
2094 the client list and mode list.
2096 * Added <Client ID> argument to the JOIN command reply, mainly
2097 for the server to identify for which client the command was
2098 originally sent. Updated protocol specs accordingly.
2100 * Added SilcDlist private_key pointer to the SilcChannelEntry
2101 in the client to support the channel private keys. Affected
2102 file is lib/silcclient/idlist.h.
2104 * Added SilcChannelPrivateKey argument to the function
2105 silc_client_send_channel_message so that application can choose
2106 to use specific private ke if it wants to. If it is not provided,
2107 the normal channel key is used, unless private keys are set.
2108 In this case the first (key that was added first) is used
2109 as the encryption key.
2111 * Implemented the support for channel private key handling.
2112 Implemented the following functions:
2114 silc_client_add_channel_private_key,
2115 silc_client_del_channel_private_keys,
2116 silc_client_del_channel_private_key,
2117 silc_client_list_channel_private_keys and
2118 silc_client_free_channel_private_keys
2120 Affected file lib/silcclient/client_channel.c.
2122 * Added the support for the private keys in the channel message
2123 sending and encryption and in the message reception and
2124 decryption. Affected funtions are
2125 silc_client_send_channel_message and silc_client_channel_message.
2127 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2129 * Added SKE's key verify callback to the client library's
2130 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2132 * Removed the statement that server (or router) must send USERS
2133 command reply when joining to the channel so that the client
2134 knows who are on the channel. Instead, the client list and
2135 client's mode list is now sent in the JOIN command reply to the
2136 client who joined channel. This is better solution.
2138 * Added function silc_server_get_users_on_channel and function
2139 silc_server_save_users_on_channel to the silcd/server.[ch].
2141 * Removed function silc_server_command_send_users from the
2144 * Do not show topic on the client library anymore. The topic is
2145 sent in the command reply notify to the application and the
2146 application must show the topic now.
2148 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2150 * Added client searching by nickname hash into the IDENTIFY and
2151 WHOIS commands in the server as they were clearly missing from
2152 them. Affected file is silcd/command.c.
2154 * Fixed a bug in private message receiving in the client library.
2155 The remote ID was freed and it wasn't supposed, now it is
2158 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2160 * Minor fix to the channel payload; allocate the data area, as it
2161 needs to be of specific length.
2163 * If the key agreement port is zero then the operating
2164 system will define the bound port. Affected files are
2165 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2167 * Added new function silc_channel_payload_decrypt into the file
2168 lib/silccore/silcchannel.[ch].
2170 * Moved the channel message etc, check from silc_packet_decrypt
2171 to applications. The library calls now a generic
2172 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2173 when the packet is either normal or special. This was done to
2174 allow more wide range of checking that was not allowed when
2175 the code was in library. Now applications can do virtually any
2176 checks to the packet and return to the library the decision how
2177 the packet should be processed. Affected files are
2178 lib/silccore/silcpacket.[ch].
2180 Added silc_server_packet_decrypt_check to the server and
2181 silc_client_packet_decrypt_check to the client library.
2183 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2184 to send with specified source and destination information.
2186 * Channel message delivery between routers was broken after the
2187 channel key distribution was fixed earlier. The channel key
2188 was used be to distributed to other routers as well which is not
2189 allowed by the protocol. Now this is fixed and channel keys
2190 really are cell specific and the channel message delivery between
2191 routers comply with the protocol specification.
2193 * Fixed various commands in server to check also the global list
2194 for the channel entry and not just the local list. The affected
2195 file silcd/command.c.
2197 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2199 * Added assert()s to buffer formatting and unformatting routines
2200 to assert (if --enable-debug) when error occurs. Affected
2201 file: lib/silcutil/silcbuffmt.c.
2203 * Changed to auto-reconnect to check whether the remote host is
2204 router and register the re-connect timeout if it is. It used
2205 to check that whether we are normal server, but router must do
2206 auto-reconnect with another router as well. Affected file
2209 * Removed the [<key len>] option from CMODE command as the cipher
2210 name decides the key length, nowadays. See the defined ciphers
2211 from the protocol specification.
2213 * Added [<hmac>] option to the CMODE command to define the HMAC
2214 for the channel. Added SILC_CMODE_HMAC channel mode.
2216 * Added [<hmac>] option for the JOIN command so that user can
2217 select which HMAC is used to compute the MACs of the channel
2220 * Added Hmac field to the Channel Message Payload. The integrity
2221 of plaintext channel messages are now protected by computing
2222 MAC of the message and attaching the MAC to the payload. The
2223 MAC is encrypted. Now, it is clear that this causes some
2224 overhead to the size of the packet but rationale for this is that
2225 now the receiver can verify whether the channel message decrypted
2226 correctly and also when private keys are set for the channel the
2227 receiver can decrypt the packet with several keys and check from
2228 the MAC which key decrypted the message correctly.
2230 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2231 lib/silccrypt/silccipher.[ch].
2233 * Added silc_hash_len to return the digest length into the
2234 lib/silcrypt/silchash.[ch].
2236 * Rewrote parts of Silc Channel Payload interface in the
2237 lib/silccore/silcchannel.[ch]. The encode function now also
2238 encrypts the packet and parse function decrypts it.
2240 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2242 * Fixed a minor formatting bug in the SKE's key material processing.
2243 It actually might have processed the keys wrong way resulting
2246 * Redefined the mandatory HMAC algorithms and added new algorithms.
2247 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2248 and hmac-md5 truncated to 96 bits. The mandatory is now
2249 hmac-sha1-96. Rest are optional (including the one that used
2250 to be mandatory). Rationale for this is that the truncated HMAC
2251 length is sufficient from security point of view and can actually
2252 make the attack against the HMAC harder. Also, the truncated
2253 HMAC causes less overhead to the packets. See the RFC2104 for
2256 * Added new [hmac] configuration section. The SKE used to use
2257 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2258 is of course wrong. The official names that must be proposed in
2259 the SKE are the ones defined in the protocol specification
2260 (hmac-sha1-96 for example). The user can configure any hmac
2261 using any hash function configured in the [hash] section. At
2262 least, the mandatory must be configured.
2264 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2266 * Added HMAC list to the SKE proposal list. It has now both
2267 hash algorithm list and HMAC list. This makes the protocol
2268 incompatible with previous versions. The SKE now seems to work
2269 the way it is supposed to work, for the first time actually.
2271 * Defined plain Hash algorithms to the protocol specification.
2274 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Implemented support for key agreement packets into the server.
2277 Added functions silc_server_key_agreement and
2278 silc_server_send_key_agreement. Other than these functions,
2279 server has nothing to do with this packet.
2281 * Added support for private message key packets into the server.
2282 Added functions silc_server_private_message_key and
2283 silc_server_send_private_message_key.
2287 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2288 called in the protocol's final callback instead in the END
2289 protocol state. This makes a little more sense and in the same
2290 time in client we can use the same protocol routines for normal
2291 key exchange and to key agreement packet handling as well.
2293 * Added to both client's and server's KE protocol context the
2294 SilcSKEKeyMaterial pointer to save the key material. We will
2295 bring the key material to the protocol's final callback by doing
2296 this. The final callback must free the key material.
2298 * Added SKE's packet_send callback into client's KE protocol
2299 context so that the caller can choose what packet sending function
2300 is used. This way we can use different packet sending when
2301 doing normal SKE when doing key agreement packet handling (in
2302 the key agreement packet handling we do not want to encrypt
2305 * Implemented the responder side of the key agreement routines
2306 in the client. The client can now bind to specified port and
2307 accept incoming key negotiation. The key material is passed
2308 to the application after the protocol is over.
2310 * Implemented the processing of incoming Key Agreement packet
2311 in the client. Added function silc_client_key_agreement to
2314 * Implemented the intiator side of the key agreement routines
2315 in the client. The client can now initiate key agreement with
2316 another remote client. The key material is passed to the
2317 application after the protocol is over.
2319 * Created client_keyagr.c to include all the key agreement
2322 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2323 SILC_TASK_CALLBACK except that it is not static.
2325 * Created client_notify.c and moved the Notify packet handling
2326 from the client.[ch] into that file.
2328 * Created client_prvmsg.c and moved all private message and
2329 private message key routines from the client.[ch] into that file.
2331 * Create client_channel.c and moved all channel message and
2332 channel private key routines from the client.[ch] into that file.
2334 * Changed silc_client_get_client_by_id_resolve to resolve with
2335 WHOIS command instead of IDENTIFY command, in the file
2336 lib/silclient/idlist.c.
2338 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Implemented the SKE's responder side to the Client library.
2342 * When FAILURE is received to the protocol do not trust it
2343 blindly. Register a timeout to wait whether the remote closes
2344 the connection as it should do it, only after that process the
2345 actual failure. This was changed to both client and server.
2347 * Added client_internal.h to include some of the structures
2348 there instead of client.h in lib/silcclient/.
2350 * Added function silc_task_unregister_by_callback to unregister
2351 timeouts by the callback function.
2353 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * Some "Incomplete WHOIS info" errors has been appearing on the
2356 log files. Took away the entry->userinfo check from WHOIS
2357 reply sending. The entry->userinfo is now " " if client did not
2358 provide one. I thought this was fixed earlier but something
2359 is wrong still. Let's see if the error still appears.
2361 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2363 * Fixed a minor bug in the login when the channel key is
2364 re-generated in the server. It used to generate the key in
2365 wrong order and thus caused problems in the channel traffic.
2367 * Fixed a minor bug in channel key distsribution after
2368 KICK command. The key was not sent to the router even though
2371 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * Added silc_ske_process_key_material_data as generic routine
2374 to process any key material as the SILC protocol dictates. The
2375 function is used by the actual SKE library but can be used by
2376 applications as well. This relates to the private message keys
2377 and the channel private keys since they must be processed the
2378 same way the normal SILC session keys. The protocol dictates
2379 this. Affected files: lib/silcske/silcske.[ch].
2381 Added also silc_ske_free_key_material to free the
2382 SilcSKEKeyMaterial structure.
2384 * Defined silc_cipher_set_key function to set the key for
2385 cipher without using the object's method function. The affected
2386 files: lib/silccrypt/silccipher.[ch].
2388 * Implemented silc silc_client_add_private_message_key,
2389 silc_client_add_private_message_key_ske,
2390 silc_client_del_private_message_key,
2391 silc_client_list_private_message_keys and
2392 silc_client_free_private_message_keys functions in the
2395 Added functions silc_client_send_private_message_key to send
2396 the Private Message Key payload and silc_client_private_message_key
2397 to handle incoming Private Message Key payload.
2399 * Added Cipher field to the Private Message Key payload to set
2400 the cipher to be used. If ignored, the default cipher defined
2401 in the SILC protocol (aes-256-cbc) is used.
2403 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2405 * Removed lib/silcclient/ops.h file.
2407 Redefined parts of the SILC Client Library API. Created new
2408 file silcapi.h that deprecates the ops.h file and defines the
2409 published Client Library API. Defined also private message key
2410 API and channel private key API into the file.
2412 This is the file that the application must include from the
2413 SILC Client Library. Other files need not be included by
2414 the application anymore.
2416 * Added new key_agreement client operation callback and also
2417 defined the Key Agreement library API for the application.
2419 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2422 is used by clients to request key negotiation between another
2423 client in the SILC network. If the negotiation is started it
2424 is performed using the SKE protocol. The result of the
2425 negotiation, the secret key material, can be used for example
2426 as private message key.
2428 Implemented the Key Agreement payload into the files
2429 lib/silccore/silauth.[ch].
2431 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2433 * Redefined ciphers for the SILC protocol. Added some new ciphers
2434 and defined the key lengths for the algorithms. Changed the
2435 code accordingly. The default key length is now 256 bits.
2437 * Fixed SKE key distribution function silc_ske_process_key_material
2438 when the key length is more than 128 bits. The default key
2439 length in SILC is now 256 bits.
2441 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2442 to indicate unsupported algorithm.
2444 * Renamed rijndael.c to aes.c and all functions as well.
2446 * Fixed a long standing channel key setting bug in client library.
2447 Weird that it has never surfaced before.
2449 * Fixed bug in channel deletion. If the entire channel is removed
2450 then it must also delete the references of the channel entry
2451 from the client's channel list as the client's channel entry and
2452 the channel's client entry share same memory.
2454 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Implemented CONNECT and SHUTDOWN commands in the client.
2458 * Implemented CLOSE command to the client.
2460 * Added the function silc_idlist_find_server_by_name into the
2461 files silcd/idlist.[ch].
2463 Added the function silc_idlist_find_server_by_conn into the
2464 files silcd/idlist.[ch].
2466 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * DIE command was renamed to SHUTDOWN. Updated the both code
2471 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2472 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2474 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2477 * Added function silc_server_create_connection function to create
2478 connection to remote router. My server implementation actually
2479 does not allow router to connect to normal server (it expects
2480 that normal server always initiates the connection to the router)
2481 so the CONNECT command is only good for connecting to another
2484 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2487 or some other client was kicked from the channel.
2489 Implemented the handling of the notify type to both client
2492 Implemented silc_server_send_notify_kicked to send the KICKED
2493 notify. It is used to send it to the server's primary router.
2495 * Implemented the KICK command into server and client.
2497 * Added `query' argument to the silc_idlist_get_client function
2498 to indicate whether to query the client from server or not if
2501 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2502 to indicate that the client is not channel founder.
2506 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Removed the rng context from SilcPacketContext structure and
2509 changed that the packet routine uses the Global RNG API.
2511 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2513 * Added support for quit message that client can "leave" on the
2514 channel when it quits the SILC. It is ditributed inside the
2515 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2517 Added silc_server_free_client_data that will take the
2518 signoff message as argument.
2520 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2522 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Updated parts of the protocol specification to keep it up
2527 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2529 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2530 payloads in one packet.
2532 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2533 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2534 use now the new List flag.
2536 * Also deprecated the following packet types: REPLACE_ID,
2537 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2539 * Added list support for Notify packet in server.
2541 * Added silc_server_send_notify_channel_change to send the
2542 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2543 the silc_server_send_replace_id.
2545 * Added silc_server_send_notify_nick_change to send the
2546 NICK_CHANGE notify type. Deprecates the function
2547 silc_server_send_replace_id.
2549 * Added silc_server_send_notify_join to send the JOIN notify type.
2550 Deprecates the function silc_server_send_new_channel_user.
2552 * Added silc_server_send_notify_leave to send LEAVE notify type.
2553 Deprecates the function silc_server_send_remove_channel_user.
2555 * Added silc_server_send_notify_cmode and
2556 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2557 types. Deprecates the silc_server_send_set_mode function.
2559 * Added SERVER_SIGNOFF notify type to indicate that server has
2560 quit. This means that all clients on the channel from that
2561 server will drop. This can be also used when netsplit happens.
2563 Deprecated REMOVE_ID packet type since it is not needed anymore
2566 Added silc_server_send_notify_server_signoff to send the
2567 SERVER_SIGNOFF notify type. Deprecates the function
2568 silc_server_send_remove_id.
2570 Added also silc_server_send_notify_signoff to send the
2571 SIGNOFF notify type.
2573 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2574 SILC protocol from this day on. Changed the protocol
2575 specification as well.
2577 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2578 notify type. It is used between routers to notify about
2579 topic changes on a channel.
2581 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2584 * Partly updated the protocol specification to comply with the
2585 changes now made. It is still though a bit outdated.
2587 * The JOIN notify type now takes one extra argument <Channel ID>.
2588 The packet used to be destined to the channel but now the
2589 JOIN type may be sent as list thus it is impossible to
2590 destine it to any specific channel. By adding this argument
2591 it is again possible.
2593 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2595 * Added CREDITS file. The CHANGES and CREDITS file will appear
2596 in the distribution as well.
2598 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2600 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2601 types in the server's silcd/packet_receive.c.
2603 * Implemented CMODE and CUMODE to work in router environment.
2605 * Fixed minor encoding and decoding buglet from the
2606 lib/silccore/silcmode.c.
2608 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2611 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2613 * Changed all SilcConfigServer* and silc_config_server* to
2614 SilcServerConfig* and silc_server_config*, respectively.
2617 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2619 * Associated the ID (client or server ID) to the Authentication
2620 Payload to avoid any possibility of forging. Updated the
2621 protocol specification and the code accordingly.
2623 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2625 * The RSA key length is now save to the RsaKey context in the
2626 key generation process in lib/silccrypt/rsa.c. The key length
2627 is now used to figure out the maximum size of the block allowed
2628 to be encrypted/signed.
2630 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2631 is equivalent to the silc_mp_mp2bin but does not allocate any
2634 * Changed silc_mp_mp2bin API to take length argument. If it is
2635 non-zero then the buffer is allocated that large. If zero, then
2636 the size is approximated using silc_mp_sizeinbase, which however
2639 * Created Global RNG API which is global RNG that application can
2640 initialize. After initializing, any routine anywhere in the
2641 code (including library) can use RNG without allocating a new
2642 RNG object. This was done to allow this sort of use of the
2643 RNG in code that has no chance to allocate RNG object. All
2644 applications currently allocate this and many routines in the
2645 library use this. Affected file lib/silccrypt/silcrng.[ch].
2647 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2648 it to use the Global RNG API.
2650 * Defined Authentication Payload into protocol specification that
2651 is used during SILC session to authenticate entities. It is
2652 used for example by client to authenticate itself to the server
2653 to obtain server operator privileges.
2655 Implemented this payload into the lib/silccore/silcauth.[ch].
2656 Implemented also routines for public key based authentication
2657 as the new protocol specification dictates.
2659 Moved definitions of different authentication methods from
2660 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2662 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2663 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2664 silc_pkcs_verify_with_hash functions into the file
2665 lib/silccrypt/silcpkcs.[ch].
2667 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * The client entry's userinfo pointer must be always valid.
2670 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2671 will fail since it requires the userinfo. Now, the userinfo
2672 is allocated as "" if actual userinfo does not exist. Actually,
2673 it must exist and it is totally Ok to drop client connections
2674 that does not announce the userinfo. However, we will make
2675 this workaround for now.
2677 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2678 to return the remote port by socket.
2680 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2682 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2683 SILC_SERVER_PENDING_EXEC and added an new macro
2684 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2685 data or when error occurs while processing the pending command.
2687 Added new argument `destructor' into silc_server_command_pending
2688 and to the SilcServerCommandPending object. This destructor is
2689 now called after calling the pending callback or if error occurs
2690 immediately. If error occurs the actual pending callback won't
2691 be called at all - only the destructor. The destructor may be
2692 NULL if destructor is not needed.
2694 All this applies for client library code as well. Similar
2695 changes were made there as well for the pending commands.
2697 In the client, the application must now allocate the
2698 SilcClientCommandContext with the silc_client_command_alloc
2701 * Added reference counter to the SilcServerCommandContext. Added
2702 function silc_server_command_alloc and silc_server_command_dup
2705 Same type of functions added to the client library for the same
2708 * Removed the cmd_ident from IDListData away since it is now
2709 global for all connections. It is the command identifier used
2710 in command sending and with pending commands. The affected file
2713 * Added reference counter to the SilcSocketConnection objecet to
2714 indicate the usage count of the object. The object won't be
2715 freed untill the reference counter hits zero. Currently only
2716 server uses this, and client ignores it. The client must be
2717 set to use this too later. The affected files are
2718 lib/silccore/silcsockconn.[ch]. Added also the function
2719 silc_socket_dup to increase the reference counter.
2721 This was mainly added because it is possible that the socket
2722 is removed underneath of pending command or other async
2723 operation. Now it won't be free'd and proper DISCONNECTING
2724 flags, etc. can be set to avoid sending data to connection that
2725 is not valid anymore.
2727 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2728 the connection. After that it sets SILC_SET_DISCONNECTED.
2729 It is, however, possible that the socket data is not still freed.
2730 The silc_server_packet_process now checks that data is not
2731 read or written to connection that is DISCONNECTED. The socket
2732 get's freed when the reference counter hits zero.
2734 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2736 * Changed the client operation API: channel_message operation's
2737 `sender' is now the client entry of the sender, not the nickname
2738 and the `channel' is the channel entry, not the channel name.
2740 In the private_message operation the `sender' is now also the
2741 client entry of the sender not the nickname.
2743 Affected file is lib/silcclient/ops.h and all applications
2744 using the client operations.
2746 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2748 * Moved the calling of ops->connect() from connect_to_server_final
2749 into receive_new_id functin since that is the point when the
2750 client is actually allowed to send traffic to network. The
2751 affected file is lib/silcclient/client.c.
2753 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2755 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2756 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2757 (if needs broadcasting) instead of broadcasting the packets one
2758 by one which would make a burst in the network traffic.
2760 * Added `broadcast' argument to the functions in silcd/server.[ch]
2761 silc_server_create_new_channel[_with_id] to indicate whether
2762 to send New Channel packet to primary router.
2764 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Added new function into the silcd/server.[ch] files:
2767 silc_server_create_new_channel_with_id to create new channel with
2768 already existing Channel ID.
2770 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2771 lib/silccore/silcpacket.h. This packet is used t send list of
2772 Set Mode payloads inside one packet. Server uses this to set
2773 the modes for the channels and clients on those channels, that it
2774 announced to the router when it connected to it. The protocol
2775 specification has been updated accordingly.
2777 * The silc_server_new_channel did not handle the packet coming
2778 from normal server as it normally does not send that. However,
2779 when it announces its channels it does send it. Implemented
2780 the support for that.
2782 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2783 into the file lib/silccore/id.h.
2785 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Fixed memory leaks in the functions silc_idlist_del_client,
2788 silc_idlist_del_channel and silc_idlist_del_server in the file
2789 silcd/idlist.c. All of those leaked like a sieve.
2791 * Fixed some small memory leaks in the client's function
2792 silc_client_notify_by_server.
2794 * Added functions into silcd/server.c: silc_server_announce_clients,
2795 silc_server_announce_channels and silc_server_announce_server.
2796 These functions are used by normal and router server to announce
2797 to its primary router about clients, channels and servers (when
2798 router) that we own. This is done after we've connected to the
2801 These functions effectively implements the following packet types:
2802 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2803 and SILC_PACKET_NEW_ID_LIST.
2805 * Added new functions into the silcd/packet_receive.[ch]:
2806 silc_server_new_id_list, silc_server_new_channel_list and
2807 silc_server_new_channel_user_list to handle the incoming
2808 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2810 * Added support of changing Channel ID in the function
2811 silc_server_replace_id. If the server that announces a channel
2812 to the router already exists in the router (with same name but
2813 with different Channel ID), router is responsible to send
2814 Replace ID packet to the server and force the server to change
2815 the Channel ID to the one router has.
2817 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2818 client that the Channel ID has been changed by the router. The
2819 normal server sends this to the client. Client must start using
2820 the new Channel ID as the channel's ID.
2822 Implemented handling of this new type into lib/silcclient/client.c
2823 into the function silc_client_notify_by_server.
2825 * Added new function silc_idlist_replace_channel_id into the files
2826 silcd/idlist.[ch] to replace the Channel ID.
2828 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2830 * Call silc_server_command_identify_check always when processing
2831 the IDENTIFY command in silcd/command.c
2833 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2835 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2836 send keepalive packets. The packet can be sent by clients,
2837 servers and routers.
2839 Added function silc_socket_set_heartbeat into the file
2840 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2841 If not set, the heartbeat is not performed. The actual
2842 heartbeat is implemented in the low level socket connection
2843 library. However, application is responsible of actually
2846 Added silc_server_send_heartbeat to send the actual heartbeat
2847 packet into silcd/packet_send.[ch]. Server now performs
2848 keepalive with all connections.
2850 * Added silc_task_get_first function into lib/silcutil/silctask.c
2851 to return the timeout task with shortest timeout. There was a bug
2852 in task unregistration that caused problems. TODO has been
2853 updated to include that task system must be rewritten.
2855 * The client library will now resolve the client information when
2856 receiving JOIN notify from server for client that we know but
2857 have incomplete information.
2859 * Rewrote parts of silc_server_remove_from_channels and
2860 silc_server_remove_from_one_channel as they did not remove the
2861 channel in some circumstances even though they should've.
2863 * Encryption problem encountered in server:
2865 The LEAVE command used to send the Channel Key packet to the
2866 router immediately after generating it. However, the code
2867 had earlier sent Remove Channel user packet but not immediately,
2868 ie. it was put to queue. The order of packets in the router
2869 was that Channel Key packet was first and Remove Channel User
2870 packet was second, even though they were encrypted in the
2871 reverse order. For this reason, MAC check failed. Now, this
2872 is fixed by not sending the Channel Key packet immediately but
2873 putting it to queue. However, this is more fundamental problem:
2874 packets that are in queue should actually not be encrypted
2875 because packets that are sent immediately gets encrypted
2876 actually with wrong IV (and thus MAC check fails). So, packets
2877 that are in queue should be encrypted when they are sent to
2878 the wire and not when they put to the queue.
2880 However, the problem is that the current system has not been
2881 designed to work that way. Instead, the packet is encrypted
2882 as soon as possible and left to the queue. The queue is then
2883 just purged into wire. There won't be any fixes for this
2884 any time soon. So, the current semantic for packet sending
2887 o If you send packet to remote host and do not force the send
2888 (the packet will be in queue) then all subsequent packets to the
2889 same remote host must also be put to the queue. Only after the
2890 queue has been purged is it safe again to force the packet
2893 o If you send all packets immediately then it safe to send
2894 any of subsequent packets through the queue, however, after
2895 the first packet is put to queue then any subsequent packets
2896 must also be put to the queue.
2898 Follow these rules and everything works fine.
2900 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Added new function silc_server_remove_clients_by_server to
2903 remove all client entries from ID list when the server connection
2904 is lost. In this case it is also important to invalidate all
2905 client entires as they hold the invalid server entry. This
2906 fixes fatal bug when server has lost connection and will reconnect
2909 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Made some sanity checks to silc_server_daemonise like to check
2912 whether the requested user and group actually exists.
2914 * Added sanity check to SKE's silc_ske_responder_finish to check
2915 that the public and private key actually is valid.
2917 * Invalidate the client's nickname when receiving Replace ID
2918 packet and the Client ID is being replaced. This means that the
2919 server will query the nickname if someone needs it (client)
2922 * Sort the ID Cache in client library when the ID Cache data
2923 has changed (needs sorting).
2925 * Do not allow for SILC client to create several connections to
2926 several servers. The client does not support windows right now
2927 and generating multiple connections causes weird behaviour.
2929 Irssi-silc client does support windows and can handle several
2930 connections without problems, see: www.irssi.org and SILC plugin.
2932 * Fixed some places where client was added to the IDList. The
2933 rule of thumb is following (in order to get everything right):
2934 If the client is directly connected local client then the
2935 `connection' argument must be set and `router' argument must be
2936 NULL to silc_idlist_add_client function. If the client is not
2937 directly connected client then the `router' argument must
2938 bet set and the `connection' argument must be NULL to the
2939 silc_idlist_add_client function.
2941 * The funtion silc_server_packet_send_local_channel actually did
2942 not check whether the client was locally connected or not. It
2943 does that now. Fixed a bug related to LEAVE command.
2945 * Fixed Remove Channel User payload parsing bug in server's
2946 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2948 * The server's silc_server_save_channel_key now checks also the
2949 global ID list for the channel as it might not be in the local
2950 list. Fixed a bug related to LEAVE command.
2952 * Is this the end of the [<unknown>] buglet that has been lurking
2953 around for a long time? A little for loop fix in server's
2954 silc_server_command_whois_parse that is used by both IDENTIFY
2955 and WHOIS command. At least, this was a clear bug and a cause
2956 of one type of [<unknown>] buglet.
2958 * WHOIS and IDENTIFY commands call the function
2959 silc_server_command_[whois/identify]_check function even if
2960 we are not router server.
2962 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Added --with-gmp configuration option. If set the GMP
2965 is always compiled in the SILC source tree. If not set then
2966 it is checked whether the system has the GMP3 installed. If
2967 it has then the GMP won't be compiled (the system's headers
2968 and library is used), if it doesn't have it then the GMP is
2969 compiled in the SILC source tree.
2971 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2973 * Changed RSA private exponent generation to what PKCS #1
2974 suggests. We try to find the smallest possible d by doing
2975 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2976 not security fix but optimization.
2978 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Added new config entry [Identity] to fork the server and run
2981 it as specific user and group. A patch from Bostik.
2983 * Imported Dotconf configuration library into lib/dotconf.
2984 This will be used to create the SILC configuration files later.
2985 It will appear in the distsribution after this commit.
2987 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * A big code auditing weekend happening. Auditing code for
2990 obvious mistakes, bugs and errors. Also, removing any code
2993 Removed files for being obsolete:
2995 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2996 inline in the file lib/silcutil/silcbuffer.h)
2998 o lib/silcutil/silcbufutil.c (the header has inline versions)
3000 Changed code to fix possible error conditions:
3002 o The buffer formatting routines now check that the destination
3003 buffer really has enough space to add the data. This applies for
3004 both buffer formatting and unformatting
3005 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3006 unformatting was changed to accomodate following rules:
3007 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3008 sent to the function while XXX_*STRING will not allocate or copy
3009 the data into the buffer. Instead it sets the pointer from the
3010 buffer into the pointer sent as argument (XXX_*STRING used to
3011 require that the pointer must be allocated already). This change
3012 makes this whole thing a bit more consistent and more optimized
3013 (note that the data returned in the unformatting with XXX_*STRING
3014 must not be freed now). The routines return now -1 on error.
3016 o Tried to find all code that use buffer_format and buffer_unformat
3017 and added return value checking to prevent formatting and
3018 especially unformatting errors and possible subsequent fatal
3021 o Changed ske->x and ske->KEY to mallocated pointers in
3022 lib/silcske/silcske.h. Fixed possible data and memory leak.
3024 o Added return value checking to all *_parse* functions. Fixed
3025 many memory leaks as well.
3027 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3028 so that buffer overflows would not happen. All code now also
3029 checks the return value as it can fail.
3031 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Added reconnection support to server if the normal server looses
3034 its connection to the router (for example if router is rebooted).
3035 The server performs normal reconnection strategy implemented
3036 to the server. Affected file silcd/server.c.
3038 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3040 * Added new packet type SILC_PACKET_SET_MODE that is used to
3041 distribute the information about changed modes (for clients,
3042 channels and clients channel modes) to all routers in the
3043 network. Updated the protocol specification accordingly.
3045 Added functions into silcd/packet_send.c and
3046 silcd/packet_receive.c: silc_server_send_set_mode,
3047 silc_server_set_mode.
3049 Added new files silcmode.[ch] into lib/silccore that implements
3050 the encoding and decoding of Set Mode Payload. Added new type
3051 SilcSetModePayload. Moved the definitions of different modes
3052 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3054 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3056 * Oops, a little mistake in server's connection authentication
3057 protocol. The protocol is not ended with FAILURE but with
3058 SUCCESS if the authentication is Ok. :) Affected file is
3061 * Implemented NICK_CHANGE notify handling in server in the file
3062 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3063 the local clients on the channel. After the changing nickname
3064 in router environment snhould work and the [<unknown>] nickname
3065 should appear no more.
3067 The silc_server_replace_id function that receives the Replace ID
3068 payload now sends the NICK_CHANGE notify type also in the file
3069 silcd/packet_receive.c
3071 * Changed WHOIS and IDENTIFY command to support the maximum amount
3072 of arguments defined in protocol specs (3328 arguments). This
3073 fixed a bug that caused problems when there were more than three
3076 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3078 * Added extra parameter, command identifier, to the
3079 silc_client_send_command so that explicit command identifier
3082 Changed that ID list routines uses specific command identifier
3083 when sending WHOIS/IDENTIFY requests to the server so that they
3084 can be identified when the reply comes back.
3086 Affected files lib/silcclient/command.[ch],
3087 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3089 * Added `sender' argument to silc_server_packet_send_to_channel
3090 to indicaet the sender who originally sent the packet to us
3091 that we are now re-sending. Ignored if NULL. Affected file
3092 silcd/packet_send.[ch].
3094 * Added some server statistics support in silcd/server_internal.h
3095 SilcServerStatistics structure and around the server code. Also
3096 send some nice statistics information when client is connecting
3099 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3101 * Fixed channel ID decoding in server's JOIN command reply in
3102 silcd/command_reply.c
3104 * Fixed braodcasting of replace ID payload to not to send it if
3105 we are standalone server in silcd/packet_receive.c.
3107 * Fixed all channel message sending routines to not to send
3108 packets to clients that has router set, since they are routed
3109 separately in the same function earlier. Affects file
3110 silcd/packet_send.c and all channel packet sending functions.
3112 * In USERS reply, res_argv[i] are not allocated, the table
3113 is allocated. Thus changed that free the table, not its
3116 * In server's whois_check and identify_check if the client is
3117 locally connected do not send any WHOIS commands - they are not
3120 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Fixed some minor bugs in client when sending WHOIS command. The
3123 arguments was in wrong order.
3125 * Removed statis function add_to_channel from server in
3126 silcd/command.c that was previously used with the joining but
3129 * Tested USERS command in router environment successfully with two
3130 routers, two servers and two clients.
3132 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Reorganized the USERS command and command reply in client library
3135 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3136 When the command is given by user we register a pending command
3137 callback that will reprocess the command after the reply has been
3138 received from the server. When reprocessing the packet we then
3139 display the information. Thus, the USERS information is displayed
3140 now in the command callback instead of in the command reply
3141 callback. The processing of the command is same as previously
3142 when server has sent the command reply in the JOINing process.
3144 * Added to USERS command in silcd/command_reply.c to join the client,
3145 we didn't use to know about, to the channel after we've created
3146 a client entry for it. Also, for clienet we did know already still
3147 check whether it is on the channel or not and add it if not.
3149 * Removed silc_server_command_join_notify as the function and its
3152 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * Changed the client's pending command handling to the same as the
3155 server's pending command handling. It is also now possible to
3156 execute command reply functions from other command reply
3157 function as the function callbacks for commands and command
3158 replies are one and same. The pending commands are not static
3159 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3160 in client connection context. Thus, pending commands are server
3161 connection specific as it is convenient.
3163 Changed the function silc_client_command_pending and
3164 silc_client_command_pending_del and added new function
3165 silc_client_command_pending_check. Removed the
3166 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3169 * Added cmd_ident, current command identifier, to the client
3170 connection context in lib/silcclient/client.h to keep track on
3171 command identifiers used in command sending. Client's command reply
3172 function handling now supports the mandatory command identifiers.
3174 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3175 funtions in client to fully support pending command callbacks.
3177 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3178 as one of the arguments to the application in the command reply
3181 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3182 before first releasing SILC but came back. Now it is removed again
3183 and should come back nomore. The FORWARDED flag was used only
3184 by the JOINing procedure by forwarding the command packet to router.
3185 Now, the JOINing procedure has been changed to more generic (due
3186 to various router environment issues) and FORWARDED is not needed
3187 anymore for anything. The protocol specification is yet to be
3190 Now, removed silc_server_packet_forward from server and the flag
3191 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3193 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Renamed NAMES command to USERS command. The NAMES was named that
3196 due to historical reasons. Now it is renamed. Also, rewrote
3197 parts of the USERS command. The nickname list is not sent anymore
3198 by the server. Only Client ID and mode lists are sent in the USERS
3199 command. Changed this also to the protocol specification.
3201 The client now resolves the names and stuff after it receives
3202 the USERS list from the server when joining to the channel.
3204 * WHOIS and IDENTIFY commands has been changed to support multiple
3205 Client ID's per command. One can now search for multiple users
3206 in the network by sending only one WHOIS or IDENTIFY command.
3207 Changed the code and the protocol specifications.
3209 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3210 uses silc_server_command_whois_parse to parse the request. */
3212 * If normal server, do not parse the WHOIS and IDENTIFY requests
3213 before sending it to the router. Saves some time.
3215 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Fixed JOIN command on client library. Wrong number of arguments
3218 used to crash the client.
3220 * Added silc_server_channel_has_global function to check whether
3221 channel has global users or not.
3223 * Added silc_server_channel_has_local function to check whether channel
3224 has locally connected clients on the channel.
3226 * The silc_server_remove_from_one_channel now checks whether the
3227 channel has global users or not after given client was removed from
3228 the channel. It also checks whether the channel has local clients
3229 on the channel anymore. If it does not have then the channel entry
3230 is removed as it is not needed anymore.
3232 * The silc_server_notify now checks on JOIN notify whether the joining
3233 client is one of locally connected or global. If it is global then
3234 the channel has now global users on the channel and that is marked
3235 to the channel entry. Also, it now saves the global client to
3236 global list who is joining and JOINs it to the channel. This is
3237 for normal server, that is.
3239 Changed silc_server_send_notify_on_channel,
3240 silc_server_packet_relay_to_channel and
3241 silc_server_packet_send_to_channel check if we are normal server
3242 and client has router set (ie. global client) do not send the
3243 message to that client, as it is already routed to our router.
3245 * Implemented LEAVE notify type handling in silc_server_notify
3248 * Tested LEAVE command in router environment successfully. Tested
3249 with two routers, two servers and two clients.
3253 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3255 * Implemented SIGNOFF notify type handling in silc_server_notify
3258 * silc_server_remove_id now removes the client entry from all channels
3259 it has joined and thusly sends SIGNOFF notify type.
3261 * Rewrote the NAMES list generation in server by removing two excess
3262 loops. The lists are created now inside one loop.
3264 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3266 * silc_server_remove_channel_user checks now also global list
3267 for channel and client.
3269 * silc_server_new_channel_user checks now both local and global
3270 list for channel and client. Fixed a bug in client id decoding.
3271 Used to decode wrong buffer.
3273 * silc_server_channel_message checks now both local and global
3274 list for channel entry.
3276 * Tested channel joining (hence JOIN) in router environment
3277 successfully. Tested with two routers, two servers and two
3280 * Tested channel message sending in router environment successfully.
3282 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Added silc_server_save_channel_key into server.[ch] to save the
3285 received channel key in Channel Key payload processing. It is
3286 also used in JOIN command reply handling.
3288 Equivalent function silc_client_save_channel_key added into
3289 client.[ch] into client library.
3291 * Changed JOIN command reply to send information whether the channel
3292 was created or not (is existing already) and the channel key
3293 payload. Changed protocol specs accordingly.
3295 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3296 the request was sent by ID and not by nickname. Crashed on
3299 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3302 now correctly save the received data.
3304 * silc_server_free_sock_user_data now notifies routers in the
3305 network about entities leaving the network.
3307 At the same time implemented functions silc_server_remove_id
3308 and silc_server_send_remove_id to receive and send REMOVE_ID
3309 packets. The packet is used to notify routers in the network
3310 about leaving entities. The ID removed will become invalid in
3313 * Added function silc_idlist_del_server into server. Removes and
3314 free's server entry from ID list.
3316 * silc_server_private_message function now checks, if we are router,
3317 that the destination ID really is valid ID, naturally.
3319 * In router when NEW_ID packet is received (for new client) the
3320 hash of the Client ID is saved in the ID Cache but the
3321 client->nickname is set to NULL, instead of putting the hash
3324 IDENTIFY command now also checks that client->nickname must be
3325 valid. If it is not if will request the data from the server who
3326 owns the client. Added new function
3327 silc_server_command_identify_check.
3329 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3330 to set the command to already allocated Command Payload.
3332 * Tested private message sending in router environment with two
3333 routers, two servers and two clients. Fixed minor bugs and now
3336 * Fixed segfault from client's NAMES command. Used to crash if
3339 * Forwarded packets must not be routed even if it is not destined
3340 to the receiver. Changed server code comply with this.
3342 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Added `require_reverse_mapping' boolean value to ServerParams
3345 structure. If TRUE (not default) the server will require that
3346 the connecting host has fully qualified domain name.
3348 If the reverse mapping is not required and hostname could not be
3349 found the IP address is used as hostname.
3351 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * Implemented version string checking to both client and server.
3354 The check is incomplete currently due to the abnormal version
3355 strings used in development version of SILC.
3357 * Changed all command functions in server to use the new
3360 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Changed char *data to unsigned char *data in ID Cache system to
3363 support binary data as ID Cache data. Changed code to support
3364 binary data in lib/silccore/idcache.c.
3366 * Renamed silc_server_packet_relay_command_reply to
3367 silc_server_command_reply as it is normal packet receiving
3368 function. Rewrote the function to accept command replys for
3369 servers and not only for clients.
3371 * Mark remote router always as registered server if we are connecting
3372 to it. Otherwise, commands sent by the router to us are ignored.
3374 * All ID List find routines now returns the ID Cache Entry pointer
3375 as well if requested.
3377 * WHOIS command works now in router environment, tested with two
3378 routers, two servers and two clients.
3380 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3381 in router environment (as it is almost equivalent to WHOIS) but
3382 hasn't been tested thoroughly. Added new functions:
3384 silc_server_command_identify_parse
3385 silc_server_command_identify_send_reply
3386 silc_server_command_identify_from_client
3387 silc_server_command_identify_from_server
3389 * Disabled route cache adding because adding two different ID's with
3390 same IP replaces the old cache entry thus giving wrong route.
3391 The entry->router->connection is always the fastest route anyway
3392 so route cache may not be needed. Of course, new routes maybe
3393 established after receiving the ID when the entry->router->connection
3394 might not be anymore the most optimal.
3396 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Add route cache for received ID for fast routing.
3400 * Added silc_server_packet_route to route received packet on router
3401 that is not destined to us.
3403 * Renamed silc_server_get_route to silc_server_route_get.
3405 * Added id_string and id_string_len fields into SilcServer to
3406 include encoded ServerID for fast comparing without excess
3407 encoding of the ID's.
3409 * Cleaned up WHOIS command on server side. Added following static
3412 silc_server_command_whois_parse
3413 silc_server_command_whois_check
3414 silc_server_command_whois_send_reply
3415 silc_server_command_whois_from_client
3416 silc_server_command_whois_from_server
3418 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3419 arguments in command replies. All command functions should be
3420 updated to use this macro.
3422 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Minor typo fixes on command reply handling on server.
3426 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3428 * Added silc_server_command_add_to_channel internal routine to add
3429 the client to the channel after router has created the channel and
3430 sent command reply to the server.
3432 * Added generic silc_server_send_command to send any command from
3435 * Use static buffer with ID rendering instead of duplicating data.
3437 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3439 * Fixed a channel user mode bug when joining to a channel server gave
3440 everybody channel founder rights, oops.
3442 * We mark ourselves as the router of the incoming server connection
3443 if we are router ourselves. This way we can check in some packet
3444 sending functions whether it is locally connected server. For
3445 incoming router connections we put NULL.
3447 * For router sending packets locally means now always sending the
3448 packet cell wide; to local clients and local servers. For normal
3449 server sending packet locally means sending it to only local
3452 * Fixed the JOIN command to really work in router environment. If the
3453 channel is created it is always created by the router. Router is
3454 also responsible of making the initial joining to the channel,
3455 sending JOIN notify to the sending server and distributing
3456 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3457 does not exist server doesn't do anything else but forward the
3458 command to the router which performs everything.
3460 * Added silc_server_send_channel_key function to send the Channel Key
3463 * Added silc_server_create_channel_key to create new channel key. The
3464 channel key is now re-generated everytime someone joins or leaves
3465 a channel, as protocol dictates. Note: channel->key_len is the
3468 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3471 packet_receive.[ch] to separate packet sending and receiving
3472 routines. The server.[ch] now includes everything else including
3473 actual packet processing (writing and reading data) and other
3476 Renamed silc_server_private_message_send_internal to
3477 silc_server_send_private_message. The routine is still though
3478 used only to relay private messages as server does not send
3479 private messages itself.
3481 Renamed silc_server_new_channel to silc_server_create_new_channel
3482 and added new function sicl_server_new_channel that handles the
3483 incoming New Channel packet. Added also new sending function
3484 silc_server_send_new_channel to send New Channel Payload.
3486 * Added new function silc_server_notify to process incoming notify
3487 packet to the server/router. Server may then relay the notify
3488 to clients if needed.
3490 * Added new function silc_server_new_channel_user to process incoming
3491 New Channel User packet. Router will redistribute the packet and
3492 send JOIN notify to its local clients and locally connected servers
3493 if needed. Normal server will send JOIN notify to its local client
3494 on same channel when received this packet. Added also corresponding
3495 sending function silc_server_send_new_channel_user to sent the
3498 * Added boolean route argument to send_notif_to_channel and
3499 packet_send_to_channel functions to attempt to route the packet
3500 if it is TRUE and send only locally if it is FALSE.
3502 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * silc_server_replace_id now broadcasts the received replace ID
3505 packet if it is not broadcast packet already. The router must
3506 broadcast to inform other routers about changed ID.
3508 * Added backpointer to server's router into SilcServer context in
3509 silcd/server_internal.h.
3511 * Fixed silc_server_packet_broadcast to send correct broadcast
3514 * The channel key is now distributed to the local client as soon
3515 as it is received from the router (in router environment) so that
3516 no other packet may be sent for the channel until client has
3519 * silc_server_remove_channel_user now broadcasts the received
3520 Remove Channel User packet if it is not broadcast packet already.
3521 The router must broadcast to inform other routers about removed
3524 * Added users field into SilcPacketContext that is a reference count
3525 of the context. One can increase the reference count by calling
3526 silc_packet_context_dup which is now changed to just increase the
3527 reference count instead of duplicating the data. The reference
3528 count is decresed by calling silc_packet_context_free that will
3529 free the data after the reference count hits zero.
3531 For now on the packet context and everything allocated into it
3532 (including the raw packet from network) must be freed by calling
3533 the new silc_packet_context_free function. Added also new function
3534 silc_packet_context_alloc that must be used now to allocate the
3535 context. This also means that if a routine is asynchronous from
3536 silc_[client/server]_packet_parse_type the packet context must
3537 be duplicated by calling silc_packet_context_dup. Otherwise it
3538 gets free'd after silc_[client/server]_packet_parse_type returns.
3539 Also, one must remember that if packet is duplicated then its
3540 reference count must be decresed by calling the free function as
3541 many times as it was duplicated.
3543 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3544 from both client and server.
3546 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3548 * Made joining to a channel working in router environment.
3550 * Cleaned up JOIN command on server side and create function
3551 silc_server_command_join_channel internal routine to make the
3554 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Changed silc_command_pending list to SilcDList. Also, added
3557 `ident' field to SilcServerCommandPending structure to identify
3558 the reply and to call correct callback.
3560 Added silc_server_command_pending_check function to replace the
3561 corresnponding macro. The silc_command_pending list is not
3564 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3565 to set identifier to previously allocated Command Payload. It
3566 is used to set identifier for command when resending Command
3569 * Added silc_command_payload_encode_payload to encode Command
3570 Payload buffer from SilcCommandPayload structure.
3572 * Added silc_argument_payload_encode_payload to encode Argument
3573 payload buffer from SilcArgumentPayload structure.
3575 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Changed WHOIS command to support router connection on server side.
3578 The whois request is always sent to router unless the server is
3579 standalone server. After server has received the reply from the
3580 router will it send the reply to the client.
3582 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3583 broadcast received broadcast packet. The function is used only
3584 by router. The broadcast packet is always sent to the router's
3587 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3588 render given ID to printable string, for log files for example.
3590 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Made basic router to router connections working. At least they
3593 can now connect to each other but nothing really works the way
3594 they are supposed - yet.
3596 * Added new initiator token to RouterConnection configuration
3597 file in silcd/serverconfig.[ch]. It is used to tell whether we
3598 are the initiator to the remote router or whether we'll expect
3599 the other end to connect.
3601 * Moved registering of listener task to silc_server_init, hence
3602 the server starts listenning as soon as it is run, even if it
3603 does not have connections to other routers. Let's see how well
3606 * Changed default connection retry timeouts for more suitable in
3609 * Removed cipher and such arguments from silc_idlist_add_client
3610 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3611 Added new function silc_idlist_add_data to add the keys and stuff
3614 * Added SilcIDListData structure and added it to SilcClientEntry
3615 and SilcServerEntry as their first field in the structure. This
3616 way we can explicitly cast the ID entries to the SilcIDListData
3617 structure and get common data for the entries. In past, we had
3618 to first check what type of connection it is and then cast it to
3619 correct ID entry type. Now, we can directly cast the opaque
3620 pointer to the SilcIDListData (no matter what ID entry it actually
3621 is) and get the data needed.
3623 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3626 in some circumstances even if threre were timeout tasks, though not
3627 IO tasks, but tasks anyway. Now fixed.
3629 * Defined SilcServerConnection structure to hold connection specific
3630 stuff about directly connected servers and routers. The definition
3631 is currently in silcd/server_internal.h. I thought about having
3632 a bit more important role fro this struct but for now it is used
3633 only when connecting to other server (or router actually).
3635 * Added connecting retry support in server when connecting to
3636 router(s). The retry feature implement exponential backoff
3637 algorithm. Also, added SilcServerParams structure to hold default
3638 parameters for server. For now, it include these retry settings
3639 and are hard coded. After server is moded to be as Silc Server
3640 Library this structure will be more important.
3642 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Changed client librarys channel->clients table to SilcList and
3645 changed code accordingly.
3647 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3649 * Changed client's channel table to SilcList and changed code
3650 accordingly. Also changed SilcChannelClientEntry to include back-
3651 pointer to the channel so that client entry can use that structure
3652 as list as well and we have fast cross-reference to the channel.
3653 This change dramatically decreased the complexity of channel
3654 handling with client entry and vice versa (removed one extra
3655 loop when searching for channel entry from many functions).
3657 * Changed server->sim from table to SilcDList and changed code
3660 * NAMES command can now be used from user interface. It will show
3661 the user list on the channel, neatly.
3663 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3664 Code now saves realname of the user if it becomes available.
3666 * Renamed configure.in to configure.in.pre and made ./prepare
3667 script to automatically add correct version string to
3668 configure.in which it creates from configure.in.pre.
3670 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * NAMES command reply now shows users mode with the nickname when
3675 * Moved silc_client_ch[u]mode[_char] functions from
3676 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3677 place sucks, they are utility functions and should be in some
3680 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3682 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3685 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * Added TRQ (efficient deque and list library) into lib/trq. This is
3690 a very good list library that is currently used in the SILC. Defined
3691 SilcList API over the library because I didn't like the API very
3692 much. See lib/trq/silclist.h for the API and examples of how to
3693 use the API. Fixed various places in the code to use the new
3694 SilcList API. The SilcList is meant for lists that has a structure
3695 already defined as a list. It is not suitable to add just some
3696 context to the list (in TRQ, the context is the list actually).
3698 So, I defined SilcDList that can be used for the purpose where
3699 predefined list structure does not exit. This can be used as
3700 such list. Now some context just can be added to the SilcDList.
3701 Currently this list is not used in the SILC just yet, though there
3702 are a lot places where this can replace dynamically allocated
3703 tables and I will fix these places, later, to use SilcDList.
3704 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3705 and use TRQ internally).
3707 Also fixed some annoying warning messages that the original TRQ
3708 code generated. Also minor changes to TRQ's Makefile.in.
3710 * Added support for querying by Client ID to both WHOIS and
3711 IDENTIFY commands into server, as required by the protocol.
3713 * Removed method function pointers from SilcBuffer structure. They
3714 weren't used to anything and just increased the context size for
3715 no good reason. This change also made silc_buffer_alloc and
3716 silc_buffer_free functions inline functions.
3718 * Disabled command flooding detection support until it's fixed so
3719 that it accepts commands in but does not execute them more than once
3722 * Added silc_net_localhost(), to return local hostname, into
3723 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3724 that must be initialized before calling silc_client_init.
3726 * Added new function: silc_server_send_notify_on_channels to send
3727 notify messages to all channels client has joined. It is assured
3728 that the message is sent only once per client.
3730 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3731 lib/silcutil/silcutil.[ch] as silc_format function. The new
3732 function is generic and is used by server as well, not only by
3733 the logging routines.
3735 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3736 the provided version string was not acceptable. Added new function:
3737 silc_ske_check_version into lib/silcske/silcske.h. The function
3738 must be implemented by the application (client or server) and it
3739 does not reside in the SKE library. The function checks the version
3740 string remote end sent.
3742 * Added back pointers (to opaque context and to SilcSocketConnection)
3743 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3745 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3746 duplicate packet context structure.
3748 * Changed `notify' client operation to send same arguments as client
3749 receives from server except for ID's. ID's are mapped to correct
3750 ID entry and that is returned. Also, if channel entry is not sent
3751 by server but the notify is for channel the channel entry is sent
3752 to application (otherwise application doesn't know that it is for
3753 channel (library gets it from packet's Destination ID)).
3755 * Added silc_client_remove_from_channels into client library to
3756 remove a client from all channels it has joined to. Used when
3757 received SIGNOFF notify from server. Added also new function
3758 silc_client_replace_from_channels to replace old ID entry with
3759 new ID entry on all channels. Used when received NICK_CHANGE
3762 * Fixed ID Cache list handling in silc_idlist_get_client in
3763 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3764 to get (or query) client by ID.
3766 * Updated TODO list.
3768 * Added connection authentication status message defined by the
3769 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3770 support for these into the code in client and server side.
3772 * Added generic function silc_client_send_command to send any command
3773 with variable argument list. Application should use this function
3774 to send commands if the command functions provided by the library
3775 does not suite for the application's user interface needs.
3777 * Added new `failure' client operation. Application is notified about
3778 received failure packet if client is executing a protocol. In this
3779 case the protocol's execution has failed.
3781 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3782 is required by the protocol.
3784 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3785 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3788 * Added status flag to SilcSKE object to indicate realtime status
3789 of the SKE protocol.
3791 * Application receives now exactly same command reply arguments as
3792 the library receives from server. However, if ID is received the
3793 corresponding ID entry is returned to the application (eg. Client
3794 ID is mapped to correct SilcClientEntry entry and that is returned).
3795 Changed command_reply client operation due to this change.
3797 * Changed all ID's in commands and in command replys as ID Payloads.
3798 Change affected both client and server side codes.
3800 All ID's sent in SILC network (with execption of ID's in SILC
3801 Packet header) are sent in ID Payload to support variable length
3804 * Server now notifies nick changes and notifies all clients on
3805 the channels about the new nickname (about the new Client ID,
3808 * Implemented CMODE command to change channel modes. Supports all
3809 channel modes defined by the protocol specs except ban and invite
3810 lists. (Also, private channel key mode is supported but support for
3811 setting private channel key in client is missing, thus, this mode
3812 has no effect on client side (except that server requires that the
3813 client uses private channel key and normal channel traffic does not
3816 Also, invite mode works per se, but INVITE command does not work
3817 yet correctly, so you can set channel as invite only channel but
3818 inviting clients to the channel does not work (it is yet to be
3819 thought what's the best way to do it).
3821 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3822 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3823 Implemented CUMODE command to change user's mode on the channel.
3824 Supports all modes defined by the protocol specs.
3826 * Added NAMES command reply to return users modes on the channel.
3828 * Removed unnecessary and slow ciphers from lib/silccrypt.
3830 * Set SO_KEEPALIVE option to connection sockets by default.
3832 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3834 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3835 redefined the Notify Payload into protocol specs.
3837 * Added silc_id_payload_parse_id to get ID directly from raw
3840 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3842 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3843 accept searching by Client ID as well.
3845 * Added support for LEAVE and SIGNOFF notify types in client library.
3847 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3848 to parse ID Payload from raw data.
3850 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Added flags parameter into silc_ske_assemble_security_properties
3853 function in lib/silcske/silcske.[ch].
3855 * Changed notify client operation to fit better for notify messages
3856 sent by server. The notify payload received from server is now
3857 passed to the application (after parsing it to SilcNotifyPayload).
3858 It is application's responsibility to retrieve the arguments
3859 from the payload and show the message the way it wants. The message
3860 sent by server is implementation specific.
3862 * Changed public keys to comply with the protocol specification.
3863 Old public keys are not supported anymore and are not compatible.
3865 * Removed nickname from Channel Payload as the latest draft removed
3866 it. The client must resolve the nickname from the NAMES command
3867 reply received when it joined the channel.
3869 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3871 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3873 * Fixed some errors in protocol specification drafts.
3875 * Created lib/silccore/silcnotify.c to implement Notify Payload
3876 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3877 generic payloads described by protocol specifications. The file
3878 includes implementations for ID Payload and Argument Payload.
3880 * Changed Command Payload implementation to use the new Argument
3881 Payload. Changed command_xxxx_payload to command_payload_xxxx
3882 to comply with SILC coding conventions.
3884 * Added suppport for Argument Payload handling in Notify Payload
3885 implementation as protocol requires it. Added the new support
3886 into server and client lib as well.
3888 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Added support for multiple nicknames on same channel. [n] is
3891 added locally to the nickname if there are more than one same
3892 nicknames on the channel.
3894 * Server now sends all nicknames that matched WHOIS request.
3895 Client also shows the list received from server.
3897 * Added TOPIC command to client side. User can now set and show
3898 current topic on channel.
3900 * Added MOTD command to client and server. Also, server sends the
3901 motd when client connects to the server.
3903 * Changed version strings to comply ISO 8601.
3905 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * Fixed protocol error handling in client library. It should now
3908 cope even if the SKE fails for some reason.
3910 * Made new protocol specification drafts for submitting to IETF.
3912 * Implemented TOPIC command to server in silcd/command.c.
3914 * Added two new notify types into lib/silccore/silcnotify.h:
3915 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3916 notify nickname change and topic setting/change on a channel.
3918 * API change of command_reply operation in client library. The
3919 application gets now the status type received from server as well.
3921 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3923 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3925 * Cras fixed and optimized the packet handling even further and
3926 it should work now. Minor change to the prototype of function
3927 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3929 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3931 * Added new function into lib/silcutil/silcschedule.[ch]:
3932 silc_schedule_with_fd to select() a specified fd. The function
3933 returns after timeout expires or data arrives or goes. The
3934 function is used by packet routines to wait that all data is
3935 received from network.
3937 * Fixed data reading from network in lib/silccore/silcpacket.c.
3938 The code now assures that all data is read from the fd and then
3939 continues packet processing. This was a bug fix since the code
3940 used to drop some data in some circumstances.
3942 * Added new function into lib/silcclient/client.[ch]:
3943 silc_client_start_key_exchange to start key exchange after
3944 connection has been established to server. The code internally
3945 now uses this funtion but its main purpose was to provide it
3946 for applications that perform their own connecting. After
3947 application has created a connection it merely calls this
3948 function to start the key exchange between client and server.
3949 The library takes care of everything else after that.
3951 Updated also lib/silcclient/README to explain the usage of
3954 * Do not send to application information that connection has
3955 been established. Application gets notified it by connect
3958 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Applied cras's patch to add silc_schedule_one function. The
3961 function runs scheduler once and returns.
3963 * Fixed the scheduler after cras messed it up. The timeout
3964 handling works now as it's supposed to work.
3966 * Added into lib/silccore/ silcnotify.h to include notify
3967 message types support. Changed silc_server_send_notify*
3968 functions, in server.[ch], to support those new notify types.
3969 Added the support for the notify types into client library,
3970 as well. Added new notify client operation into ops.h in
3973 * Changed silc_server_packet_send_to_channel to send normal
3974 packets instead of just channel message packets. The function
3975 is now used to send the notify packets to channels. It is not
3976 used to send channel message packets anymore, as server never
3979 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3980 va_arg()s as it seems to require it nowadays. I guess, if SILC
3981 is compiled with older va_arg() the new code should work anyway.
3983 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Splitted core library. Core library (lib/silccore) includes
3986 now only SILC protocol specific core (and common) components.
3987 Created new utility library (lib/silcutil) that includes more
3988 generic purpose stuff. The stuff for util library was taken
3989 from the old core library. This was minor and easy split.
3991 * Created SILC Client Library (lib/silcclient) that includes
3992 implementation of the SILC client without user interface. This
3993 was major move from silc/ directory. The code has been changed
3994 so that it is transparent towards the user interface. The
3995 silc/ directory includes now the same user interface as before
3996 and it uses the new client library. Read lib/silcclient/README.
3997 Basicly, the client library performs everything else related
3998 to SILC except user interface handling. Also, configuration
3999 files are considered to be part of user interface and library
4000 does not handle them.
4002 This change also changed a lot of structures, function naming etc.
4003 Most important change was that SilcClientWindow object was
4004 renamed to SilcClientConnection in the client library. Created
4005 also new file lib/silcclient/ops.h. Also added new files
4006 silc/local_command.[ch] and silc/client_ops.[ch].
4008 All these changes were made to make it easier for user interface
4009 designers to create what ever user interface for the SILC client
4012 It is also expected that the server will be moved to lib
4013 directory as well and SILC Server Library will be created;
4014 sometimes in the future.
4016 * Removed Local commands from lib/silccore/silccommand.h as
4017 they are application specific and new client library does not
4018 handle any of those anymore.
4020 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4021 old client implementation in silc/.
4023 * Added support for callback functions in SILC_LOG_* macros.
4024 Application can now set its own callbacks that will be called
4025 instead of using the default functions that will always print
4026 the debug messages to stderr (or stdout). Also, debugging can
4027 now be disabled by setting silc_debug to FALSE and re-enabled by
4028 setting it to TRUE. Note, that logging will still work even
4029 if debugging is disabled.
4031 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4032 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4033 silc_log_reset_debug_callbacks.
4035 * To enable debugging in silc client one must give now -d
4036 option on command line.
4038 * Changed silc_schedule_init to automatically allocate task queues
4039 if they are not allocated before calling it.
4041 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Added GMP 3.1 into math library.
4045 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4048 a channel in SILC network. The packet is used by servers and
4049 routers to notify other routers that user has left a channel.
4050 This little feature was missing until now. Added the feature
4051 to protocol specification as well.
4053 Added functions: silc_server_send_remove_channel_user and
4054 silc_server_remove_channel_user into server.[ch].
4056 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4057 lib/silccore/silcpacket.h. However, they are not implemented
4060 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Fixed joining to a channel and sending channel messages
4063 between server and router. The channel message sending should
4064 now work inside a cell.
4066 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Fixed the private message sending between server and router.
4069 The private message sending should now work inside a cell.
4071 * Added silc_server_replace_id into server.[ch] to replace
4072 existing ID in the SILC network.
4074 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4075 and silc_idlist_replace_server_id into idlist.[ch] in server.
4077 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Fixed the server to server connections. Server can again now
4080 connect to router. Router to router connections probably does
4083 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4085 * Added dynamic protocol registering support. Now protocols can
4086 registered and unregistered on the fly. Patch by cras.
4088 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Added lib/contrib directory to hold routines that some platforms
4091 don't have but are needed by SILC.
4093 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4094 into lin/contrib to provide getopt() and getopt_long() for
4095 those who don't have it.
4097 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4099 * Added AWAY command to client. When away message is set and
4100 client receives a private message packet the client automatically
4101 replies to the sender with the away message.
4103 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4104 bug seemed to be the cause of recent problems when compiling
4107 * Added version detection support to SKE protocol specification
4108 and added the new changes to the SKE implementation as well.
4109 There were other minor changes in the SKE protocol as well.
4111 Many changes in lib/silcske/silcske.[ch] and in
4112 lib/silcske/payload.[ch].
4114 * Added ^U functionality, clear input line. Patch from cras.
4116 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4118 * Mainly small bugfixes on core library. Fixed some debugging
4119 logging and buffer overflow in silclog.c.
4121 * Updated config.sub and config.guess on the distribution tree.
4123 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4125 * Added command lagging support in server. Client may execute
4126 commands now only once in two seconds.
4128 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Optimized packet reception. MAC computation and checking is now
4131 also more optimized. A lot previously duplicated code is now
4132 used as generic by both client and server.
4134 * Fixed key pair generation in clientutil.c
4136 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Added into lib/silccore/silcbufutil.[ch] new function;
4139 silc_buffer_realloc.
4141 * Moved generic packet sending/encryption functions to
4142 lib/silccore/silcpacket.[ch] from client and server. Some
4143 rewriting of the functions.
4145 * Moved all generic packet reception/decryption functions to
4146 lib/silccore/silcpacket.[ch] from client and server. The
4147 packet processing is now much cleaner in both client and server.
4148 These were major changes in both client and server.
4150 * Created many common functions in server to do packet sending.
4151 Previously code were duplicated a lot, this has been removed
4154 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Rewrote major parts of the ID cache system. Don't know
4157 whether it is better now or not but at least the API is more
4160 * Major rewrite on ID cache stuff on client because of the ID
4161 cache API changes. Added idlist.c to client.
4163 * Also major rewrite on ID cache stuff on server as well.
4164 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4165 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4166 in hand, instead they are all put into the ID cache system now.
4167 All server_idlist_* routines uses ID cache now instead of
4168 traversing its own lists (those lists does not exist anymore).
4169 SilcIDList though still exists. Also, SilcXXXEntry's are
4172 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Finally made the SKE implementation compliant to the protocol
4175 specification. All mp integers are now binary encoded as
4176 opposed being HEX encoded.
4178 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4181 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4182 functions: silc_[encode/decode]_pem. Also added function
4183 silc_encode_pem_file to PEM encode with newlines ('\n') for
4186 * SILC public keys are now encoded either PEM or binary. Same
4187 option is for private keys as well. By default private keys
4188 are binary encoded and public keys PEM encoded. Silly HEX
4189 encoding were removed.
4191 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4192 function to create fingerprints.
4194 * Fixed a bug in SHA1; does not change the original data anymore.
4196 * Partly implemented INFO command on client and server side.
4197 Fixed CLEAR command. Changes to SERVER command; show current
4198 server(s) when giving command without arguments. Added
4199 VERSION command to client.
4201 * Added check to server that unregistered connections cannot
4202 execute commands (unless it is specificly allowed).
4204 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Fixed screen refresh.
4208 * Fixed channel joining bug from client. On some circumstances
4209 client tried to join to a channel it had already joined.
4211 * Added public key verification process into client's protocol.c.
4212 The client now verifies the public key from user and saves
4213 it into ~./silc/serverkeys/ directory.
4215 Added into: clientutil.[ch]: silc_client_verify_server_key.
4217 * Changed SKE protocol's silc_ske_initiator_finish function
4218 to accept callback function that verifies the received public
4219 key. Removed old silc_ske_verify_public_key function.
4221 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4223 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4224 silc_pkcs_private_key[_data]_set.
4226 * Made the password and public authentication more cleaner in
4227 server's protocol.c.
4229 * Removed historic and obsolete protocol `channel_auth' from
4230 both client and server.
4232 * Removed wrong way of sending command status messages from
4233 server to client in server's command.c. The old way violated
4234 protocol specification.
4236 Changes to silccore/silccommand.[ch]: removed
4237 silc_command_encode_status_payload -> not needed anymore,
4238 changed silc_command_encode_payload_va to accept extra
4239 argument on variable argument list. The argument type must
4240 now be provided to the function. Also, added new function:
4241 silc_command_encode_reply_payload_va which is same as
4242 normal command_encode_payload_va except command status type
4243 is provided as extra argument.
4245 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Added ~./silc directory handling. The directory includes the
4248 public and private keys for the client.
4250 Added silc_client_check_silc_dir, silc_client_create_identifier
4251 and silc_client_load_keys.
4253 * Implemented SILC protocol compliant public key. Added public
4254 and private key saving to and loading from files.
4256 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4257 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4258 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4259 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4260 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4262 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4263 silc_pkcs_load_[public/private]_key.
4265 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Added silc_server_get_route (route.[ch]) to get connection
4268 data for the fastest route for given ID.
4270 * Implemented INVITE command on client and server. The command
4271 were re-defined in the SILC Protocol Specification and the
4272 implementation now complies with the specification.
4274 * Implemented PING command on client and server.
4276 * Implemented NAMES command on client and server. The server side
4277 supports currently only normal server not router server yet.
4278 Some changes to NAMES definition in SILC protocol specification.
4280 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Implemented LEAVE command on client and server.
4284 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4285 again. This change was made to the protocol as well. Server
4286 should not violate the protocol specification anymore.
4288 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4291 was tested. SOCKS4 was not but should work anyway.
