1 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
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 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
12 * Do not add regex.h for WIN32. The affected file
13 includes/silcincludes.h.
15 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
16 not work yet 100%. It generates the DLL's automatically
17 when compiling with --with-win32 under cygwin.
19 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
21 * lib/contrib/regex.c is not compiled on WIN32.
23 * Added silc_net_get_socket_opt function to the
24 lib/silcutil/silcnet.h.
26 * Added includes/silcwin32.h for WIN32 specific includes
29 * Do not use ptime structure or any of the posix process
30 functions on WIN32 in lib/silccrypt/silrng.c.
32 * Added silc_gettimeofday to provide generic function
33 for struct timeval on all platforms. Added the function
34 to lib/silcutil/silcutil.h.
36 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
38 * Moved the lib/silccore/silcsockconn.[ch] to the utility
39 library as they clearly belong there. As a plus side we
40 can make the actual socket connection routines platform
43 Added also new generic function silc_socket_read and
44 silc_socket_write (that used to be silc_packet_[read/write].
45 The implementation of these are platform specific.
47 * Added WIN32 specific routines of silc_socket_[read/write]
48 to lib/silcutil/win32/silcwin32sockconn.c.
50 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
52 * Added preliminary support for native WIN32 compilation under
53 cygwin (using the -mno-cygwin option for GCC) to the
54 ./configure.in.pre. The --with-win32 now prepares the
55 compilation for native WIN32.
57 * Rewrote the SILC Scheduler interface in the file
58 lib/silcutil/silcschedule.h. The scheduler is now context
59 based and does not have anymore any global static scheduler.
60 Moved the Unix scheduler to the lib/silcutil/unix/ directory
61 and created lib/silcutil/win32 directory for WIN32 based
64 * Added Unix specific network routines to the
65 lib/silcutil/unix/silcunixnet.c and the old
66 lib/silcutil/silcnet.c includes now only generic routines.
68 Added WIN32 specific network routines to the
69 lib/silcutil/win32/silcwin32net.c.
71 * Added Unix specific utility functions from the
72 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
74 * Added WIN32 SILC Scheduler to the file
75 lib/silcutil/win32/silcwin32schedule.c. The code is of course
78 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
80 * Do not handle JOIN notify in the server if the target client
81 is not registered (idata->registered == FALSE). The affected
82 file is silcd/packet_receive.c.
84 * Update the nickrec->founder in event_cumode in the Irssi SILC
85 client. Affected file irssi/src/silc/core/silc-channels.c.
87 * Fixed the CUMODE_CHANGE notify handling in the server when
88 server and router are announcing their clients on channels.
89 Now the mode changes are saved and notified correctly. The
90 affected file is /silcd/packet_receive.c.
92 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
93 They really did not replace the cache entry in the ID Cache.
94 Now they do that. Affected file silcd/idlist.c.
96 * Fixed the KICK notify handling in the Irssi SILC client to
97 update the channel records so that the kicked client does not
98 appear to be on the channel. The affected file is
99 irssi/src/silc/core/silc-channels.c.
101 * Always update the conn->current_channel when executing command
102 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
104 * Fixed the KILL notify handling in Irssi SILC client to remove
105 the killed client on all channels.
107 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Fixed the silc_parse_command_line to remove extra spaces
110 from the start and end of the arguments. Affected file is
111 lib/silcutil/silcutil.c.
113 * Cancel and free any active protocol in the function
114 silc_server_close_connection. Affected file silcd/server.c.
116 * Cancel and free any active protocol in the function
117 silc_client_close_connction. Affected file is
118 lib/silcclient/client.c.
120 * Do not execute the KILL command for clients that are in
121 history (ie. they are not in the network). Affected file is
124 * Fixed KILL notify handling, client does not crash anymore.
125 Affected file irssi/src/silc/core/silc-channels.c.
127 * Reduced the default packet buffer size from 2048 to 1024 in
128 lib/silccore/silcpacket.c.
130 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
131 counter to the SKE context that is incresed when the SKE library
132 performs async operation outside the library. If the outside
133 process frees the SKE context and FREED status will be set
134 and the library will detect after the sync operation that the
135 libary is freed. The affected files are
136 lib/silcske/silcske[_status].[ch].
138 * Resolve the client entry information in the function
139 silc_client_channel_message to assure that NULL pointer is not
140 passed as client entry to the application. */
142 * Fixed the task timeout calculation to assure that there is
143 never negative timeouts. The affected file is
144 lib/silcutil/silcschedule.c.
146 * Fixed the channel user mode notification sending in server.
147 It was sent point-to-point to the router (or to server by router)
148 but it needs to be destined to a channel. The routines now
149 supports sending the channel user mode notifys to the channels
150 when announcing clients and channels. Affected files are
151 silcd/server.c and silcd/packet_receive.c.
153 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
154 It did not actually replace the old channel entry in the cache.
155 Affected file lib/silcclient/client_notify.c.
157 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
159 * Fixed a possible crash in silc_packet_send_prepare. It now
160 assures always that there is enough space in the buffer and
161 at the tail area of the buffer (for MAC).
163 Fixed the inbound buffer reallocation in silc_packet_read.
164 It was old code and did not handle the reallocation correctly.
167 The affected file is lib/silccore/silcpacket.c.
169 * Fixed buffer overflow in silc_parse_nickname in the file
170 lib/silcutil/silcutil.c.
172 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
174 * make install generates new server keys only if there is not
177 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
179 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
180 Added check that if the NOREPLY is set then we will not send
181 the away message. This avoids infinite loop of away messages
182 if both clients are away. The affected file is
183 lib/silcclient/client_prvmsg.c.
185 * Fixed client crash if /NICK was given without arguments.
186 Affected file lib/silcclient/command.c.
188 * Server does not send the invite list in INVITE command back
189 to the client if the list was not altered. Added this notion
190 to the protocol spec as well. Affected file silcd/command.c.
192 Fixed possible crash in INVITE command by checking the
193 value of silc_server_get_client_route command.
195 * Fixed the INVITE notify type handling. The arguments are now
196 taken in correct order and client does not crash. The affected
197 file is irssi/src/silc/core/silc-channels.c.
199 Removed the "Inviting xxx to channel" message from the
200 client library away and let the application handle it.
201 Affected file lib/silcclient/command.c. Added that message
202 to Irssi SILC client's message formats.
204 * Fixed CMODE command crash in client. It now checks the
205 amount of arguments correctly and does not crash. The affected
206 file is lib/silcclient/command.c.
208 * Do not create new channel automatically in silc_channels_join
209 but check whether the channel by that name already exists.
210 Affected file irssi/silc/core/silc-channels.c.
212 * Do not send the SERVER_SIGNOFF to router if the disconnected
213 entity was the router. Affected file silcd/server.c.
215 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
216 SILC client as it was missing from there.
218 Added the handling of the KICK notify to the Irssi SILC client
219 as it was missing. Added "you have been kicked" message to
220 Irssi SILC client's message modules formats.
222 Added the handing of the KILL notify to the Irssi SILC client
223 as it was missing. Added the kill message module formats
226 The affected file is irssi/src/silc/core/silc-channels.c.
228 * The router did not save the channel mode the server announced.
229 Affected file silcd/packet_receive.c.
231 * Fixed a possible crash in INFO command in server. If the
232 server did not provide the server info it crashed. Affected
233 file silcd/command.c.
235 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
237 * Fixed the GETKEY command in the server to check also the
238 global list. Otherwise the GETKEY would not work correctly
239 in normal SILC server. Affected file silcd/command.c.
241 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
243 * Fixed GETKEY crash, it crashed if the command did not succseed.
245 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
247 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
248 is now real and not just an macro interface to GMP.
250 Removed the entire GMP from the source tree and imported new
251 NSS MPI library instead. Reason for removing GMP is that it is
252 extremely large and compiles extremely slow. The NSS MPI
253 is only a few files and compiles in less than 10 seconds.
254 The speed is also about the same as GMP. The MPI is imported
257 If the system has GMP installed we will still use the GMP.
258 If it is not then the NSS MPI will be compiled.
260 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
262 * Merged a long nickname (127 characters long) crash bugfix from
263 Irssi CVS tree. Affected file irssi/src/core/misc.c.
265 * Merged a freed memory reference bugfix from Irssi CVS tree.
266 Affected file irssi/src/core/commands.c.
268 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Added the server's public key sving and verification to the
271 server when performing the SKE. This was missing and the
272 remote server's (or router's) public key was accepted without
273 checking whether we have it previously or trust it at all.
274 Affected file silcd/protocol.c.
276 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
278 * Check in the silc_server_timeout_remote if protocol is active
279 and make sure that the protocol's final callback is called so
280 that all memory if freed. Affected file silcd/server.c.
282 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
284 * silc_server_whois_send_reply crashed the server if the nickname
285 was 127 characters long. Affected file silcd/command.c.
287 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
289 * Added sanity check to the silc_server_new_client. If the hostname
290 is provided inside username then check that the provided hostname
291 really is the same as the resolved one. If the hostname was not
292 resolved then check it from the public key. Affected file is
293 silcd/packet_receive.c.
295 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
296 if the server disconnected us and the connection is not valid
297 anymore. Affected file irssi/src/silc/core/silc-channels.c.
299 * Moved the silc_client_[chmode|chumode|chumode_char] away from
300 the library to the lib/silcutil/silcutil.[ch].
302 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
304 * Close log file after open. Affected file
305 lib/silcutil/silclog.c.
307 * Check whether sock == NULL in silc_client_send_packet and return
308 if it is. Affected file lib/silcclient/silcclient.c.
310 * Check rec->entry == NULL in the Irssi SILC Client before
311 sending the channel message. Affecte file is
312 irssi/src/silc/core/silc-servers.c.
314 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
316 * Merged a splitted window bugfix from Irssi CVS tree. The
317 affected file is irssi/src/fe-text/textbuffer-view.c.
319 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
320 It did not print nickname.
322 * Improved the distributions system a bit.
324 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
327 irssi/src/fe-text/gui-window.c.
329 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
330 to in-active server. The affected file is
331 irssi/src/silc/core/client_ops.c.
333 * Resolve the client in USERS command reply if the entry does
334 not have username resolved. The affected file is
335 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
336 command to WHOIS command to really resolve stuff. The USERS
337 is not used any more in any critical section so WHOIS can
338 be used even though it might be slower than IDENTIFY.
340 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
343 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
345 * Changed the protocol API a bit more consistent in the
346 lib/silccore/silcprotocol.[ch].
348 * Changed the following headers to ROBODoc format:
350 lib/silccore/silcpayload.h
351 lib/silccore/silcprotocol.h
352 lib/silccore/silcsockconn.h
354 All core library headers are now formatted.
356 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Fixed a bug in Irssi SILC client; do not show that you are
359 server/router operator if you really are not. Affected file is
360 irssi/src/silc/core/client_ops.c.
362 * Renamed silc_command_free_payload to silc_command_payload_free.
363 Affected file lib/silccore/silccommand.h
365 * Added silcmath.h to include the prototoypes of various routines
366 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
369 * Changed the following headers to ROBODoc format:
371 lib/silccore/silcchannel.h
372 lib/silccore/silccommand.h
373 lib/silccore/silcid.h
374 lib/silccore/silcidcache.h
375 lib/silccore/silcmode.h
376 lib/silccore/silcnotify.h
377 lib/silccore/silcpacket.h
378 lib/silcmath/silcmath.h
380 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
382 * Added checking to the server code not to start the server if
383 ciphers and stuff are not configured properly. Affected files
384 silcd/serverconfig.[h] and silcd/server.c.
386 * Changed the layout of the header files of the public interfaces
387 in the SILC libraries. The new layout supports ROBODoc
388 documentation tool (and some others) so that it is easy to create
389 a library reference manual. All the other headers and source
390 code must still follow the CodingStyle document. Also source
391 code must not include these ROBODoc stuffs, only the headers.
392 Furthermore, all public interface headers must now be named
393 by using `silc' prefix, example: silcapi.h, silccipher.h.
394 Some files were renamed due to this. All the other headers
395 must not be used as public interfaces. I will update the
396 CodingStyle document later. Changed following headers, so far:
398 lib/silcclient/silcapi.h
399 lib/silccore/silcauth.h
400 lib/silccore/silcprivate.h
401 lib/silccrypt/silcdh.h
403 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
407 * Removed silc_client_packet_send_flush from the client library
408 as it is not needed. Affected file lib/silcclient/client.[ch].
410 * Added printing of message of unresolved authentication method
411 to the Irssi SILC client. Added it to the module formats.
412 Removed the same message from the client library.
414 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
416 * Added new distribution feature, DISTLABEL. Every distribution
417 can define own preprocessor label that can be used in the
418 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
419 file distributions, acconfig.h.pre and prepare.
421 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
423 * Added Makefile.defines_int to include the actual definitions
424 for Makefile.defines.in. Tested the new distribution system,
425 created distributions and tested installation.
427 * Added AWAY message printing to the Irssi SILC client. Added
428 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
430 * Added SCONNECT command to call the SILC's CONNECT command.
431 Cannot use CONNECT directly since Irssi uses that internally.
432 Affected file irssi/src/silc/core/silc-servers.c.
434 Added ACTION local command. It is same as ME command but takes
435 the channel as mandatory argument.
437 Rewrote some of the Irssi's help files to suite for SILC
440 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
442 * Added Makefile.defines[.in] that should for now on be included
443 in all Makefile.am file in the source tree. That file includes
444 all common compilation definitions for SILC source tree.
446 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
448 * Minor changes to the ./prepare script to change the package
449 name according the distribution name to the configure.in.
451 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
453 * Created new distribution system. Added file `distributions'
454 that defines all the distributions that can be created out of
455 the SILC source tree. The ./prepare script now reads that
456 file to determine how to prepare the distributions. The
457 first argument to the ./prepare is the name of the distribution
458 and second is the version of the distribution. If given
459 without arguments it creates the default (toolkit) distribution
460 with the default version (defined in ./prepare).
462 All Makefile.am files that are subject to the distributions
463 are now named as Makefile.am.pre. These are ./Makefile.am
464 and lib/Makefile.am. Others may be changed later.
466 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
468 * Added invite list, ban list, some key management and connection
469 error message printing to module formats in the Irssi SILC client.
471 * Added new silc_client_set_away_message to set the away message
472 that is back to the person who sent private message. The
473 affected file lib/silcclient/silcapi.h and the
474 lib/silcclient/client_prvmsg.c.
476 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * Fixed the private message sending in the Irssi SILC client,
479 added local command KEY to the Irssi SILC client.
481 Added key management and key agreement message formats to the
482 irssi/src/fe-common/silc/module-formats.[ch].
484 Added USERS (alias WHO) printing, server/router operator
485 indication and LIST command printing to the module formats.
487 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
489 * Fixed channel joining notify handling, cumode notify handling
490 from Irssi SILC client.
492 * Added SILC specific module-formats to the Irssi SILC client so
493 that SILC specific message hilighting, colors etc is possible.
494 Affected file irssi/src/fe-common/silc/module-formats.[ch].
496 Added channel mode, channel user mode, actions, notices,
497 whois and whowas printing to the the module-formats.c.
499 * Fixed a bug in channel deletion in the server. The channel
500 is not left to the cache even if the channel founder auth mode
501 is set when there are no users anymore on the channel. Affected
504 * The silc_net_localhost now resolves the entire hostname including
505 the domain name. Affected file lib/silcutil/silcnet.c.
507 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
509 * Changed the ask_passphrase client operation to be ascynchronous.
510 It has now a completion callback and a context that the
511 application must call after it has got the passphrase from
512 the user. Affected files lib/silcclient/silcapi.h,
513 lib/silcclient/protocol.c, lib/silcclient/command.c and
516 Added SilcAskPassphrase callback that the application calls
517 to deliver the passphrase to the library.
519 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
520 The public key verification and especially a certificate
521 verification is asynchronous procedure.
523 Added new SILC_SKE_STATUS_PENDING status to indicate the
524 request is pending and a callback will be called to finalize
527 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
528 indicate that remote end did not send its public key (or
529 certificate), even though we require it. Added check for this
530 condition in the SKE. This was a security bug, now fixed.
532 Defined new SilcSKEVerifyCbCompletion callback that is called
533 when the verification process is completed.
535 The affected files lib/silcske/silcske_status.h and
536 lib/silcske/silcske.[ch].
538 * Changed the verify_public_key client operation to be async
539 as well. Defined SilcVerifyPublicKey callback that is used to
540 indicate the success of the public key verification process.
542 Changed the server and client to use the new async client
545 * Changed the Irssi SILC client's internal scheduler to be called
546 twice as many times as it used to be. As a result the client
547 should be a bit faster now. Affected file is
548 irssi/src/silc/core/silc-core.c.
550 * Added support to Irssi SILC client of asynchronous public key
551 verification and passphrase inquiry. Affected file is
552 irssi/src/silc/core/silc-core.c.
554 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
556 * Do not say "You have left channel %s" in client library.
557 Moved it to the application. Affected files are
558 lib/silcclient/command.c and silc/client_ops.c.
560 * Fixed silc_client_get_clients. Command context was not
561 duplicated and was freed memory in the callback. Affected
562 file lib/silcclient/idlist.c.
564 * Do not say "you are now talking..." on JOIN command in the
565 client library. The appliation must handle it.
567 * Do not say ".. changed topic to" in command reply in the
568 client libary. The application must handle it.
570 * Fixed TOPIC command sending in the client library.
572 * Fixed a memory leak in silc_client_command_free in the file
573 lib/silcclient/command.c.
575 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
577 * Imported a modified version of Irssi client to the source tree.
578 The Irssi will be used to create a new client called
579 Irssi SILC. Imported to irssi/.
581 Added silc_core_init_finish function to the Irssi. Affected
582 file irssi/configure.in.
584 A lot changes in the Makefile.ams around the irssi tree.
586 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
588 * Do not rehash if the new size is same as the old size of the
589 hash table, in the silc_hash_table_rehash*. The affected file
590 lib/silcutil/silchashtable.c.
592 * Replaced hash_table_del_by_context calls from the server
593 (when channel->user_list and client->channels) to the
594 hash_table_del as it is sufficient and faster.
596 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
598 * Added silc_hash_table_list, silc_hash_table_get and the
599 SilcHashTableList structure to provide an alternative way to
600 traverse the hash table. The affected files are
601 lib/silcutil/silchashtable.[ch].
603 * Changed the server's idlist routines to use the hash table
604 routines to optimize the code.
606 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
608 * Replaced the client entry's `channel' list and channel entry's
609 `user_list' list to hash tables for optimized lookup. Changed
610 the code to use the hash table interface around the code.
611 Affected file lib/silcd/idlist.[ch].
613 * Added `auto_rehash' boolean argument to the function
614 silc_hash_table_alloc to indicate whether the hash table should
615 auto-rehash when it thinks is appropriate time. It will
616 increase the hash table size if the there is twice as much
617 entries in the table than the size of the table, and will
618 decrease the size if there are twice as less entries than
619 the size of the table.
621 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Fixed silc_xxx_get_supported to not crash at some circumstances.
625 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
627 * silc_idcache_purge_by_context deletes the entry now by context
628 as it is supposed to do. Affected file lib/silccore/idcache.c.
630 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
631 client is not anymore valid (WHOWAS givens the info) and not
632 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
634 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
636 * Removed the `data' and `data_len' arguments from the ID Cache
637 interfaces and added `name' argument. ID Cache does not handle
638 anymore the binary data only a names associated with given ID.
640 * When hashing a Client ID with silc_hash_id the entire ID is
641 not hashed anymore, instead only the hash of the Client ID is
642 hashed. This way we can access the Client ID from the cache
643 with Client ID but with the hash of the ID (which is a hash of
644 the nickname) as well without any difference in performance.
646 Added also silc_idcache_find_by_id_one_ext to do one on one
647 searching when we have the actual ID. Added also function
648 silc_hash_client_id_compare. The affected files are
649 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
651 * When hashing the name associated with a ID it is always done
652 in lowercase. This way we can access the cache without worrying
653 about case-sensitivity, even though, for example nicknames are
656 * Fixed a bug in server with channel message sending. It put
657 wrong ID type as destination ID. The affected file
660 * silc_idcache_del_by_context now deletes from all hash tables
661 by context. Affected file lib/silccore/idcache.c.
663 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
665 * Changed the client library to use the new ID Cache interface.
666 Changes around the source tree.
668 * Added silc_hash_table_rehash_ext to rehash with specific
669 hash function. Affected file lib/silcutil/silchashtable.[ch].
671 * Added silc_hash_string_compare to compare two strings in the
672 hash table. Affected file lib/silcutil/silcutil.[ch].
674 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
676 * Added new function silc_idcache_del_by_context into the
677 lib/silccore/idcache.[ch].
679 * Changed the server's ID list routines to use the new ID Cache
680 interface. Changes around the source tree.
682 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
684 * Added silc_hash_table_del[_by_context]_ext functions in to the
685 lib/silcutil/silchashtable.[ch].
687 Removed silc_hash_table_find_all* routines and added new
688 silc_hash_table_find_foreach to replace them.
690 Added silc_hash_table_replace_ext function as extended
691 replacing function. Separated the simple hash table interface
692 from the extended hash table interface in the file
693 lib/silcutil/silchashtable.h.
695 * Fixed minor bugs and changed it to use some of the new
696 hash table functions in lib/silccore/idcache.c
698 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
700 * Added new function silc_hash_table_find_all to return all keys
701 in the hash table by the specified key. As the hash table is
702 collision resistant it also makes it possible to have several
703 duplicate keys in the hash table. This function may be used to
704 find all of the keys from the hash.
706 Added user_context arguments to the SilcHashFunction,
707 SilcHashCompare and SilcHashDestructor to deliver user specified
710 Added new fuctions silc_hash_table_find[_all]_ext to do
711 extended lookup with specified hash and compare functions and
712 specified user contexts.
714 Added new function silc_hash_table_add_ext to add the key
715 with specified hash function and user context.
717 Added new function silc_hash_table_foreach to traverse all
718 entrys in the hash table. Added SilcHashForeach callback
721 Added new function silc_hash_table_del_by_context to delete
722 the entry only if the context associated with the key matches.
724 Affected files are lib/silcutil/silchashtable.[ch].
726 * Removed silc_hash_[server/client/channel]_id and added just
727 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
728 silc_hash_id_compare to compare two ID's using as the hash table
729 comparison function. Added also silc_hash_data to hash
730 binary data and silc_hash_data_compare to compare it.
732 * Removed silc_idlist_find_client_by_hash as it is not needed
733 anymore. Affected file silcd/idlist.[ch].
735 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
736 to use internally the SilcHashTable. The new ID Cache is a lot
737 faster than the old one. Some of the ID Cache interface was also
738 rewritten and obsolete and stupid functions were removed.
740 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
742 * Added entry_count field to the SilcHashTable to keep the number
743 of the entries in the table. Implemented the function
744 silc_hash_table_rehash. Added new function
745 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
747 Fixed a minor bug in silc_hash_table_free.
749 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
750 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
751 into the lib/silcutil/silcutil.[ch].
753 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Implemented a collision resistant hash table into the
756 lib/silcutil/silchashtable[ch]. See the header and the source
757 for the SilcHashTable API.
759 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Merged dotconf version 1.0.2 into lib/dotconf.
763 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
765 * Do not compile anything in lib/silcsim/* if the SIM support
766 is not enabled. The tree should now compile without problems
769 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
771 * Compiled the SILC under cygwin. Compiled and tested briefly
772 without problems. More tests needed. The SIMs didn't compile
775 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
777 * Fixed possible crash in silc_get_username in the
778 lib/silcutil/silcutil.c.
780 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * Fixed a va_arg in silc/client_ops.c.
784 * Oops, RC5 routines were named AES and caused some problems
785 when not using SIM's. Affected file lib/silccrypt/rc5.c.
787 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * Added new SilcIDIP structure into the lib/silccore/id.h and
790 replaced the old `ip' fields from all SILC ID's to that type.
791 This is a step towards IPv6 support.
793 The silc_id_get_len takes now the ID as an extra argument.
794 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
795 both IPv4 and IPv6 based ID's.
797 The affected files are lib/silccore/id.[ch] and other files
798 around the tree using these routines.
800 * Removed the ID length arguments in server from various
801 silc_server_send_notify_* routines -> they are not needed
804 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
806 * Fixed memory leak in silc_encode_pem_file in the file
807 lib/silcutil/silcutil.c.
809 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
811 * Check minor version as well in the SKE. Affected files are
812 silcd/protocol.c and lib/silcclient/protocol.c.
814 * Added --identifier option to the server so that an identifier
815 can be when creating the public key for the server. Affected
816 file is silcd/silcd.c.
818 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
819 lib/silccrypt/silcpkcs.c.
821 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
823 * Register default ciphers and stuff when using -C option with
824 the server. Affected file sildc/silcd.c.
826 * Put back the servers public key filename format, it is better
827 than the new one. For now, the client keys are saved with the
828 new filename format. The affected file silc/client_ops.c.
830 * Implemented the Cipher API for the rest of the ciphers that
831 did not implement it or implemented it the wrong way.
833 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
835 * Register default ciphers and stuff when using the -S option
836 in the client. Affected file silc/silc.c. Same also when
837 creating new key pair with -C option.
839 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
841 * Fixed the silc_verify_public_key client operation function to
842 save the public keys differently. The fingerprint is now
843 used as filename and not the hostname. This way also the
844 client keys are saved uniquely and not with hostnames. The
845 affected file is silc/client_ops.c.
847 * Trimmed the silc_hash_fingerprint function to remove extra
848 whitespaces from the end of the fingerprint. The affected
849 file is lib/silccrypt/silchash.c.
853 * Added silc_cipher_register_default function to register all
854 default ciphers. It can be used when configuration files
855 does not exist and the application does not want any specific
856 ciphers in any specific order.
858 The SilcDList is now used as silc_cipher_list dynamically
859 allocated cipher list. Removed the static list all together
860 and now all ciphers must be allocated to the dynamic list.
861 The silc_cipher_alloc routine was changed to check only the
864 All silc_cipher_* routines that used to return int returns
867 The affected files lib/silccrypt/silccrypt.[ch].
869 * The same thing was done to silc_hash_* as for silc_cipher_*
870 routines. Affected files lib/silccrypt/silchash.[ch].
872 * The same thing was done to silc_pkcs_* as for silc_cipher_*
873 routines. Affected files lib/silccrypt/silcpkcs.[ch].
874 Added also silc_pkcs_[un]register[_default] functions.
875 Removed the data_context from the PKCS API.
877 * Added silc_hmac_register_default function to register default
878 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
879 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
880 to unregister all hmacs at once.
882 * Register the default ciphers, hash functions, PKCSs and HMACs
883 if client's configuration file does not exist. The affected
886 * The client did not load the hash functions from the SIM
887 modules at all. Added support for this. Affected file is
890 * When decoding public key with silc_pkcs_public_key_decode, check
891 the supported algorithm only if PKCS are registered. Affected
892 file lib/silccrypt/silcpkcs.c. The same was done with the
893 silc_pkcs_private_key_decode.
895 * Fixed the SILC List routines to keep the list always in order.
896 It used to change the list's order when traversing the list but
897 not it preserves the order. Affected file lib/trq/silclist.h.
899 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
901 * Added the client library to use the SilcSocketConnection's
902 reference counter (by silc_socket_dup) to prevent the bug that
903 the socket object may be freed underneath async operation.
905 * The name resolv library checking fixes in the configure.in.pre.
908 * Created new version of the protocol drafts for future
909 development. The -03 drafts are the ones that will be changed
910 in the trunk now and the -02 will remain as they are.
912 * Send list of CUMODE notifys to the router when announcing
913 the channel users to the router. Affected file silcd/server.c.
914 If the router receiving channel founder CUMODE for a channel
915 that already has channel founder it will send CUMODE notify
916 to the sender to remove the channel founder rights from the
917 announced client. Affected file silcd/packet_receive.c.
919 * The CUMODE notify may now use Server ID as well as the entity
920 who changes the mode. Updated protocool specs.
922 * Updated INSTALL and README files.
924 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * New web pages in the http://silc.pspt.fi. The pages was
931 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
933 * Implemented the [DenyConnectin] config section in the server.
934 Added silc_server_config_denied_conn to check whether incoming
935 connection is denied. Affected file silcd/serverconfig.[ch].
937 * Do not check the ports when checking the incoming configuration
938 data if the port is 0, meaning any. Affected file is
939 silcd/serverconfig.c.
941 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * Fixed buffer overflow in silc_string_compare in the file
944 lib/silcutil/silcutil.c.
946 * Fixed double free in silc_server_command_leave in the file
949 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
951 * Fixed the version checking in the server. Affected file is
954 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Fixed the configuration data fetching when accepting new
957 connections in the server. Affected file silcd/server.c.
959 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
961 * Added `sender_entry' argument to the function
962 silc_server_packet_relay_to_channel so that we can check
963 whether some destination actually belongs to the same route
964 the sender belongs (ie, we must not resend the packet to the
965 sender). Affected file silcd/packet_send.[ch].
967 * Added `servername' field to the SilcClientEntry in the server
968 to hold the name of the server where client is from. Affected
969 file is silcd/idlist.h.
971 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
973 * Moved the channel message encrypting in the router betwen
974 router connections from silc_server_channel_message to the
975 silc_server_packet_relay_to_channel since we want to check
976 whether we have anybody channel before encrypting anything.
977 Affected files silcd/packet_[receive/send].c.
979 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
981 * Fixed the [AdminConnection] server config section to support
982 multiple entries. Affected file silcd/serverconfig.c.
984 * Added support into the server to check the validity of the
985 incoming connection before executing any KE or authentication
988 * The connection configuration is now saved to the KE and
989 connection auth protocol contexts and not fetched anymore in
990 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
992 * The local hosts listenning address and port is also resolved
993 now when starting the server. We want to have the socket object
994 to include the real address and port for the listener. Added
995 new function silc_net_check_local_by_sock into the files
996 lib/silcutil/silcnet.[ch].
998 * Fixed a broadcast bug in server -> do not broadcast if we
1001 * Fixed a routing bug. Do not route broadcast packets ever.
1002 Broadcast packets must be processed always and not routed since
1003 they may be destined to some other host than yourself and thus
1004 would get routed without no good reason. Affected file is
1007 * Added function silc_server_config_is_primary_route to check
1008 whether primary router connection has been configured (a router
1009 configuration that we are initiating). If there is not, we
1010 will assume that there is only two routers in the SILC network
1011 and we will use the incoming router connection as our primary
1012 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1014 * Changed the order of the broadcasting. Broadcast _after_ the
1015 packet has been processed not before. Affected file is
1018 * Fixed a [ClientConnection] parsing bug. The port was never
1019 parsed correctly thus resulting to port 0. Affected file
1020 silcd/serverconfig.c.
1022 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1023 argument and did not set the broadcast packet flag. Affected
1024 file silcd/packet_send.c. Fixed same bug in the function
1025 silc_server_send_notify as well.
1027 * If we receive NEW_ID packet for our own ID in the server, ignore
1030 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1034 * Removed the nickname from the Private Message Payload.
1035 Updated the code and the protocol specs.
1037 * Updated protocol specs for submitting to the IETF.
1039 * Tweaked the Random Number Generator a bit. Affected file
1040 lib/silccrypt/silcrng.c. Exported a new function
1041 silc_rng_[global]_add_noise which can be used to add more
1044 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1046 * Do not parse packets with different timeout when protocol
1047 is active -> may cause problem with rekey. Affected file
1050 * When server receives signoff notify it must not create
1051 new channel key if the client is on any channels since the
1052 sender of the signoff notify will create it.
1054 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1056 * Added printing of error messages during SKE protocol from the
1057 failure packet sent by server during SKE. Affected file
1060 * Removed the client's failure_callback handling with timeout
1061 and handle it immediately when received.
1063 * The SKE library returned wrong type in SUCCESS and FAILURE
1064 packets. They must be 32 bit MSB not 16 bit MSB.
1066 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1068 * Ok, rewrote the logic of the re-key and now it seems to work.
1069 I tested it on high traffic with frequent re-keys without
1070 problems. Added hmac_receive (and renamed hmac to hmac_send)
1071 in SilcClientConnection in lib/silcclient/client.h and
1072 in SilcIDListData in silcd/idlist.h. Also, removed the
1073 SilcPacketParserContext's cipher and hmac fields as they are
1074 not needed anymore and actually caused some problems when
1075 the ciphers and hmac's changed underneath the packet parser.
1077 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * If re-key protocol is active then process the incoming packets
1080 synchronously since we must assure that icoming packets encrypted
1081 with the old key is processed before the new keys is set to
1082 use. This is true other packets than for REKEY packets.
1083 Affected file silcd/server.c. The same was done to client library
1084 as well, affected file lib/silcclient/client.c.
1086 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1088 * Fixed bug in client and server to accept the force send if
1089 the packet is send from silc_[server/client]_packet_process
1090 function. Otherwise the packets are never delivered, oops.
1092 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1094 * Disable force sending of packets when REKEY protocol is active.
1095 We must assure that no packet is sent directly when rekey is
1096 performed. All packets must be sent through packet queue.
1097 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1098 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1099 function is silc_[server/client]_packet_send_real to check
1102 * Replaced the SIM paths from example config files to
1103 /usr/local/modules. Also, make install creates now
1104 /usr/local/silc/logs directory to hold all the SILC server
1107 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Made the configure.in.pre work on Solaris. Patch by salo.

1118 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1120 * When MAC computation fails the silc_packet_decrypt returned 0
1121 even though it was supposed to return -1. Fixed this. The
1122 affected file is lib/silccore/silcpacket.c.
1124 * Do not replace the config files in /etc/silc (in make install)
1125 if they already exist. Affected file ./Makefile.am.
1127 * Do not send re-key packets immediately but through packet queue.
1128 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1130 * Changed silc_net_check_host_by_sock to return FALSE if the
1131 IP/DNS could not be resolved. Though, it returns the IP address
1132 now even if it could not resolve it (but returns also FALSE).
1133 Affected file lib/silcutil/silcnet.[ch].
1135 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Added silc_pkcs_decode_identifier to decode the public key's

1139 Added also silc_pkcs_free_identifier. Added also new context
1140 SilcPublicKeyIdentifier.
1142 * Added -S option to the silc client. It is used to dump the
1143 contents of the specified public key file.
1145 * Changed the PKCS api to return the public key length when
1146 setting the public key.
1148 * Fixed a fatal bug in the public and private key file loading.
1149 Affected file lib/silccrypt/silcpkcs.c.
1151 * Execute the packet parsing for client with zero (0) timeout
1152 if the protocol is active. Affected file silcd/server.c.
1154 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1156 * Made the key generation options to the silcd program. Added
1157 -C option, equivalent to client's option.
1159 * Added new [ServerKeys] config section to the server. It
1160 configures the server's public and private key.
1162 * Defined generic Public Key Payload into the protocol
1163 specification to send specific type of public keys and
1166 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1167 public key or certificate.
1169 * Implemented the GETKEY command to the server and to the
1170 client library and on user interface.
1172 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1174 * Made preliminary `make install' work.
1176 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1178 * Added SilcServerRekey context into silcd/idlist.h.
1180 * Added the PFS support as defined in the specification to the
1181 SKE protocol. Affected files lib/silcske/*.c.
1183 * Added `ske_group' field to the SilcServerRekey context to hold
1184 the number of the SKE group that is used with PFS in re-key.
1185 Affected file silcd/idlist.h.
1187 * Added PFS re-key support to the server. Affected file is
1190 * Added silc_protocol_cancel to cancel execution of the next
1191 state of the protocol. Affected file is
1192 lib/silccore/silcprotocol.[ch].
1194 * Added the re-key support with and without PFS to the client
1195 library. Re-key is performed once in an hour, by default.
1197 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1198 Added silc_client_rekey_callback and silc_client_rekey_final.
1199 Affected files are lib/silcclient/protocol.[ch] and
1200 lib/silcclient/client.[ch].
1202 * Removed the `hmac_key' and `hmac_key_len' fields from the
1203 SilcClientConnection structure; not needed. Affected file is
1204 lib/silcclient/client.h.
1208 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1210 * Do not ask whether user wants to use the negotiated private key
1211 for private messages, just use it. Affected file is
1212 silc/local_command.c.
1214 * Added `send_enc_key' and `enc_key_len' fields to the
1215 SilcIDListData structure since they are needed in the re-key
1216 phase. Affected file is silcd/idlist.[ch].
1218 * Implemented the simple re-key protocol into the server.
1219 Affected files silcd/server.c and silcd/protocol.[ch]. The
1220 re-key will be performed once in an hour, by default.
1222 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1223 Added silc_server_rekey, silc_server_rekey_callback and
1224 silc_server_rekey_final.
1226 * Removed Tunneled flag from the protocol. Updated the code
1227 and the specifications.
1229 * Adde `pfs' field to the SilcIDListData to indicate whether
1230 the PFS is to be performed in the re-key. Affected file is
1233 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1235 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1236 int64 of at least the xintXX size. If void * is less that 4
1237 bytes uint32 * will be used. Defined bool as boolean.
1239 * Changed _ALL_ unsigned long and unsigned int to uint32,
1240 unsgined short to uint16 in the source tree.
1242 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1243 not handle clients that has entry->data.registered == FALSE.
1244 They are not in the network anymore. Affected file is
1247 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1249 * Implemented the sending of the SERVER_SIGNOFF notify in the
1250 server. Affected file is silcd/server.c.
1252 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1253 Added also silc_notify_payload_encode_args into the
1254 lib/silccore/silcnotify.[ch].
1256 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1257 Affected file silcd/packet_receive.c.
1259 * Implemented the SERVER_SIGNOFF notify handling in the client
1260 library. Affected file lib/silcclient/client_notify.c. Also,
1261 implemnted the printing of the SERVER_SIGNOFF info to the
1262 application. Affected file silc/client_ops.c.
1264 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1265 if the deleting was successful. Affected file silcd/idlist.[ch].
1267 * Added support for public key authentication in the connection
1268 authentication protocol in the client library. Affected file
1269 lib/silcclient/protocol.c.
1271 * Changed the server's silc_idlist_get_clients_by_* interface
1272 to support already allocated array so that new entries may be
1273 added to pre-allocated array. Affected file silcd/idlist.[ch].
1274 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1275 and command replies.
1277 * All command reply functions in the server now calls the
1278 pending command callback even if error occured. This way the
1279 error will be delivered to the client as well. Affected files
1280 silcd/command.c and silcd/command_reply.c.
1282 * Fixed INFO command to return local server's info if no server
1283 was provided. Affected file lib/silcclient/command.c.
1285 * Removed RESTART command for good. Updated the code and the
1288 * Rewrote parts of the task system. It is a bit simpler now.
1289 Removed unsued task priorities. The affected files are
1290 lib/silcutil/silctask.[ch].
1292 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1294 * Moved the USERS printing from the library to the application.
1295 Affected files lib/silcclient/command.c and silc/client_ops.c.
1297 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Added channel key re-key support. The re-key is perfomed
1302 only by the router and is done once in an hour. Added `rekey'
1303 field to the SilcChannelEntry in the server. Affected files
1304 silcd/server.c and silcd/idlist.h.
1306 * Added silc_task_unregister_by_context into the file
1307 lib/silcutil/silctask.[ch].
1309 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1311 * Added SILC_UMODE_GONE mode to indicate when the client is not
1312 present in the SILC network. Added also support to the local
1313 command AWAY that will set this mode. Added support of showing
1314 "xxx is gone" in WHOIS command. The USERS command shows the
1315 gone status as well.
1317 * Fixed setting server and router operator privileges in the
1318 server's UMODE command. Affected file silcd/command.c.
1320 * Merged the SKE KE1 and KE2 payloads into one payload. The
1321 new KE payload is equivalent to the old KE2 payload.
1323 Cleaned up the SKE Start Payload parsing. It now uses the
1324 simple buffer unformatting to do the parsing. A lot faster
1327 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1328 to the SKE that is used to indicate whether both of the SKE
1329 parties should perform authentication. By default only the
1330 responder performs authentication. By setting this flag also
1331 the initiator must do authentication. By default it is unset
1332 since in normal SKE case, client to server connection, only
1333 the responder should do authentication. When doing SKE between
1334 two clients both should perform authentication. Updated the
1335 code and the protocol specs.
1337 * A little fix to IDENTIFY command in the server. Search the
1338 client first by hash not nickname. Affected file is
1341 * Fixed the silc_client_close_connection to support closing
1342 the client to client connections wihtout deleting too much
1343 data. Affected file lib/silcclient/client.c.
1345 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1346 are received if protocol used to be active but is not anymore
1347 the application would crash due to NULL pointer dereference.
1348 Affected files silcd/server.c and lib/silcclient/client.c.
1350 * Added `hash' field to the SilcClientConnection to include
1351 the hash function negotiated in the SKE protocol.
1353 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1354 to set the channel founder authentication data. A client can
1355 claim the founder rights later by providing the authentication
1356 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1357 This way the channel founder can regain the channel founder
1358 privileges even it is left the channel. This works only on
1359 local server and the client must be connected to the same
1360 server to be able to regain the founder rights. Updated the
1361 protocol specs accordingly.
1363 Added support to the CMODE command in the client to set the
1364 founder auth data. Read the README to see how to set it.
1366 Added support to the CUMODE command to claim the founder
1367 rights. Read the README to see how to do it.
1369 Added support for the founder authentication to the Channel
1370 Entry in the server. Affected file silcd/idlist.h.
1372 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1373 server's CMODE command. Affected file silcd/command.c.
1375 * Added the following new functions into lib/silccore/silcauth.[ch]:
1376 silc_auth_get_method and silc_auth_get_data.
1378 * The server now saves the remote hosts public key to the
1379 SilcIDListData pointer. Affected file silcd/protocol.c.
1381 * The normal server now does not remove the channel entry from
1382 the cache if the founder authentication data is set. It used
1383 to remove it if the founder was the last one on the channel on
1384 the server and left the channel. The auth data is saved and
1385 if the channel is re-joined later the old entry is used with
1386 the old auth data. Affected files silcd/command_reply.c and
1389 * Removed the `pkcs' field from the SilcIDListData structure
1390 in the server; it is not used. Affected file silcd/idlist.h.
1392 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1394 * Fixed packet processing on slow links. Partial packets were
1395 never re-processed because the incoming data buffer was cleared
1396 by the application. Application must not directly clear the
1397 sock->inbuf, the packet processing routines handle it. Fixed
1398 this in client library and in server.
1400 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Fixed the WHOIS and IDENTIFY send reply function to really
1403 check whether to send list or just one entry. Affected file
1406 * Cleaned up the LEAVE command's channel key distribution. The
1407 affected file silcd/command.c.
1409 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1410 can enforce the channel mode as well. In that case the ID
1411 includes the ID of the server. The code now enforces the
1412 mode change if the router have different mode than the server.
1414 * The notify client operation with CMODE_CHANGE notify can now
1415 return NULL client_entry pointer if the CMODE was not changed
1416 by client. Application must check for this.
1418 * Added <Server ID> argument to INFO command to support server
1419 info fetching by Server ID.
1421 * Added silc_server_announce_get_channel_users to get assembled
1422 packets of channel users of the specified channel. Affected
1423 file silcd/server.[ch].
1425 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1426 was freed underneath the ID Cache.
1428 * Re-announce clients when the server received CHANNEL_CHANGE
1429 notify from the router. Affected file silcd/packet_send.c.
1431 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1433 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1434 crashed since it did not handle the fact that there is no cipher
1435 called "3" and didn't check the error condition. Now fixed.
1437 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1438 flag. It can be used to send message requests.
1440 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1442 * Implemented the RESTART command in the client.
1444 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1445 notice type messages. Added notice printing to the user
1448 * The channel keys are not re-generated if the channel's mode
1449 is PRIVKEY, ie private key on the channel exists. Affected
1450 files silcd/server.c and silcd/command.c.
1452 * Fixed a little bug in channel message delivery when channel
1453 private keys are set in the server. Affected file is
1454 silcd/packet_send.c.
1456 * Changed the setting on channel->on_channel = TRUE from the
1457 silc_client_save_channel_key to the JOIN command reply. The
1458 key payload is not received if the private channel key is set.
1459 Affected file lib/silcclient/command_reply.c and the
1460 lib/silcclient/client_channel.c.
1462 * When the CMODE_CHANGE notify is sent and the channel private
1463 key mode is removed the channel key must be re-generated in
1464 other cells as well. Added this support for the router in the
1465 silcd/packet_receive.c.
1467 * Added new local command NOTICE to send notice message on
1468 channel. Affected file silc/local_command.[ch].
1470 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1472 * Added new local command ME to the client. It is used to send
1473 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1474 some action. Affected file silc/local_command.[ch].
1476 * Changed channel_message and private_message client operations
1477 to deliver the message flags to the application. Added also
1478 the `flags' arguments to the silc_client_send_channel_message
1479 and silc_client_send_private_message functions. Affected file
1482 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1484 * Redefined the Private Message Payload to support private message
1485 keys and to support the new private message flags. Updated
1486 the protocol specs. Flags makes it possible to have for example
1487 CTCP style messages.
1489 * Added new type SilcPrivateMessagePayload and defined an API
1490 for it in the lib/silcclient/silcprivate.[ch].
1492 * Tested private message private keys successfully. Tested the
1493 private message key set, unset and list commands with the new
1496 * Redefined the Channel Message Payload to include the channel
1497 message flags (equal with private message flags) to support
1498 for example CTCP style messages.
1500 * Defined some of the message (for channel and private message)
1501 flags. Updated the protocol specs and added the flags to the
1502 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1504 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1506 * Added SilcKeyAgreementStatus type to the key agreement routines
1507 to indicate the current status and error if one occured.
1508 The status types are defined in the lib/silcclient/silcapi.h.
1510 * Added new local command KEY that is used to set and unset private
1511 keys for channels, set and unset private keys for private messages
1512 with remote clients and to send key agreement requests and
1513 negotiate the key agreement protocol with remote client. The
1514 key agreement is supported only to negotiate private message keys,
1515 it currently cannot be used to negotiate private keys for channels,
1516 as it is not convenient for that purpose.
1518 * Fixed a minor pending callback setting bug in the function
1519 silc_client_get_client_by_id_resolve, now the function works.
1520 Affected file lib/silcclient/idlist.c.
1522 * Added function silc_net_get_local_port to get local bound
1523 port by socket. Added to lib/silcutil/silcnet.[ch].
1525 * Added `sockets' and `sockets_count' fields to the SilcClient
1526 object. They hold the sockets of the listenning sockets in
1527 the client. Listenning sockets may be for example the key
1528 agreement server. Affected file lib/silcclient/client.[ch].
1529 Added functions the silc_client_add_socket and the
1530 silc_client_del_socket. They are exported to the application
1533 * Added ~./silc/clientkeys to support other client's public keys.
1535 * Renamed verify_server_key client operation to verify_public_key
1536 and added one argument to indicate the type of the connection
1537 (server, client etc.).
1539 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1541 * Added silc_server_connection_auth_request to handle the
1542 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1543 silcd/packet_receive.[ch].
1545 * Added silc_server_send_connection_auth_request into the
1546 silcd/packet_send.c to send the connection auth request packet.
1548 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1551 * Fixed the public key authentication in responder side in the
1552 server. The `auth_data' pointer includes the SilcPublicKey
1553 not the path to the public key. Affected file silcd/protocol.c.
1555 * Implemented the public key authentication in the initiator side
1556 in the server. Affected file silcd/protocol.c.
1558 * Removed the [RedirectClient] config section from the server
1559 configuration. Is not needed and I don't want to implement it.
1561 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Cleaned up the CMODE command in the server. It now works
1564 correctly and supports all the modes defined in the protocol.
1565 Affected file is silcd/command.c.
1567 * Added `hmac_name' field to the SilcChannelEntry in the server
1568 to hold the default HMAC of the channel. It can be set when
1569 creating the channel (with JOIN command). Affected files
1572 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1573 type to indicate the change of the current cipher and hmac
1574 on the channel. Client can safely ignore the <cipher> argument
1575 (if it chooses to do so) since the CHANNEL_KEY packet will
1576 force the channel key change anyway. The <hmac> argument is
1577 important since the client is responsible of setting the new
1578 HMAC and the hmac key into use.
1580 * Fixed the CMODE command in the client library as well.
1582 * Tested CMODE command in router environment successfully.
1584 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Show the version of the remote client (or server) when connecting
1587 to the server. It is logged to the log file. Affected file
1588 is silcd/protocol.c.
1590 * Fixed the KILLED notify handling in the client library. The
1591 client must be removed from all channels when receiving the
1594 Also, do not remove the client entry when giving the KILL
1595 command but when the KILLED notify is received.
1597 * Removed silc_idlist_find_client_by_nickname from the server.
1598 Not needed anymore. Affected files silcd/idlist.[ch].
1600 * Implemented the CHANNEL_CHANGE notify type handling to the
1601 server. Affected file silcd/server.c.
1605 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1607 * Added silc_server_send_notify_invite to send the INVITE
1608 notify between routers.
1610 * Implemented the INVITE command correctly to the server.
1612 * Implemented the INVITE notify type handling in the server.
1614 * Implemented the INVITE command to the client library and on the
1617 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1619 * Added function silc_server_get_client_resolve to find the
1620 client entry by ID from all ID lists and then resolve it
1621 (using WHOIS) if it cannot be found. Affected file is
1624 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1626 * Implemented the BAN command to the client library.
1628 * The JOIN command in the server now checks the invite list
1631 * Changed the silc_command_reply_payload_encode_va and the
1632 silc_command_payload_encode_va to support that if argument is
1633 NULL it ignores and checks the next argument. Affected file
1634 lib/silccore/silccommand.c.
1636 * Added silc_server_send_notify_ban to send the BAN notify
1637 type between routers.
1639 * Chaned the silc_notify_payload_encode to support that if
1640 argument is NULL it ignores and checks the next argument.
1641 Affected file lib/silccore/silcnotify.c.
1643 * Tested ban lists in router environment successfully.
1645 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1647 * Implemented BAN command to the server, in silcd/command.[ch].
1649 * Removed the BAN and INVITE_LIST modes from the CMODE command
1652 * Added function silc_string_match to regex match two strings.
1653 Affected files lib/silcutil/silcutil.[ch].
1655 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * Redefined parts of the SilcChannelEntry in the server to support
1658 the new ban and invite lists.
1660 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1662 * Redefined the INVITE command. The same command can be used to
1663 invite individuals to the channel but also to manage the invite
1664 list of the channel (to add to and remove from the invite list).
1665 Updated the protocol specs.
1667 * Added new command SILC_COMMAND_BAN that can be used to manage
1668 the ban list of the channel. Updated the protocol specs.
1670 * Removed the channel modes: the SILC_CMODE_BAN and the
1671 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1672 in the CMODE command. The equivalent features are now available
1673 using INVITE and BAN commands. Updated the protocol specs.
1675 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1676 in the network about change in the current ban list. The notify
1677 type is not used by the client.
1679 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1680 support the invite lists.
1682 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Added new function silc_string_regexify that converts string
1685 including wildcard characters into regex string that can
1686 be used by the GNU regex library. Added into the file
1687 lib/silcutil/silcutil.[ch].
1689 Added silc_string_regex_combine to combine to regex strings
1690 into one so that they can be used as one regex string by
1691 the GNU regex library. Added into the file
1692 lib/silcutil/silcutil.[ch].
1694 Added silc_string_regex_match to match two strings. It returns
1695 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1697 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1699 * Imported GNU regex to the soruce tree into lib/contrib.
1700 Fixed some compiler warning from the regex.c.
1702 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1704 * Fixed MOTD command in the server to work in router environment.
1706 * Fixed the MOTD command in the client library to support
1707 the server argument in the command.
1709 * Added `nickname_len' argument to the silc_idlist_add_client
1710 in the server, as the `nickname' argument may be binary data
1713 * Added silc_idlist_get_channels to return all channels from
1716 * Implemented LIST command to the server. Affected file is
1719 * Implemented the LIST command to the client library and on the
1722 * Added [<user count>] argument to the LIST command reply.
1723 With private channels the user count is not shown.
1725 * Updated TODO and README.
1727 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1729 * The client entry's data.registered must be TRUE even with
1730 global client entry on global client list. The data.registered
1731 is used to check whether the client is anymore in the network,
1732 for example with WHOWAS command so it must be valid.
1734 * Fixed the WHOWAS command in the server. It now actually works
1735 in router environment. Added function into silcd/command_reply.c
1736 silc_server_command_reply_whowas_save.
1738 * Added silc_idlist_purge function to the silcd/idlist.c
1739 to periodically purge the ID Cache.
1741 * Fixed INFO command in the server. It works now in router
1742 environment. Added <server name> argument to the INFO command
1743 reply. Updated the protocol specs.
1745 * Fixed minor bug in silc_idcache_purge to not purge if the
1746 expire value is zero.
1748 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1749 they were buggy because of the WHOWAS information.
1751 * Fixed local command MSG to handle the async resolving of
1752 the remote client properly. It used to fail the first MSG.
1753 Affected file silc/local_command.c.
1755 * Added `data_len' field to SilcIDCache context.
1757 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1759 * Update TODO. Todo in commands in the server.
1761 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1763 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1764 used by routers as broadcast packet to inform other routers
1765 about the changed user mode.
1767 Implemented the notify handling in the server. Affected file is
1768 silcd/packet_receive.c. Added the function
1769 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1771 * Added new generic Channel Payload and deprecated the New Channel
1772 Payload. The New Channel Payload is now the generic Channel
1775 * Added new argument `mode' to the silc_server_send_new_channel
1776 as it is required in the Channel Payload now.
1778 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1779 and created a new and real SilChannelPayload to represent the
1780 new generic Channel Payload. Implemented the encode/decode
1781 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1783 * Added silc_server_get_client_channel_list to return the list
1784 of channels the client has joined for WHOIS command reply.
1785 Affected file silcd/server.[ch].
1787 * Implemented the channel list sending in the WHOIS command reply
1788 in server and in the client.
1790 Implemented the channel list displaying on the user interface
1791 as well. Affected file silc/client_ops.c.
1793 * Added silc_channel_payload_parse_list to parse list of Channel
1794 Payloads. It returns SilcDList list of SilcChannelPayloads.
1795 Client for example can use this function to parse the list of
1796 channels it receives in the WHOIS command reply. The caller
1797 must free the list by calling silc_channel_payload_list_free.
1798 Affected files lib/silccore/silcchannel.[ch].
1800 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1802 * Added one new argument <user mode> to the WHOIS command reply
1803 to return the mode of the user in SILC. Updated the protocol
1806 Implemented it to the server and client.
1808 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * Fixed the mode printing on the user interface on joining.
1811 Affected file silc/client_ops.c.
1813 * Implemented the UMODE command and user modes in general to the
1814 client library and to the user interface.
1816 * Implemented the UMODE command to the server.
1818 * The server now sends UNKNOWN_COMMAND error status if client sends
1819 unknown command. Affected file silcd/command.c.
1821 * All server commands now handle the command identifier the right
1822 way when sending the command reply to the client. The client can
1823 use to identify the command replies with the identifier.
1825 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1827 * Added silc_server_get_client_route to resolve the route to
1828 the client indicated by the client ID. Affected file is
1831 * Added silc_server_relay_packet as general function to relay
1832 packet to arbitrary destination. This deprecates functions
1833 like _send_private_message_key, _relay_notify etc. Affected
1834 file is silcd/packet_send.[ch].
1836 Removed silc_server_send_key_agreement,
1837 silc_server_send_private_message_key and
1838 silc_server_packet_relay_notify functions from the file
1839 silcd/packet_send.[ch].
1843 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1844 server. Affected file silcd/packet_receive.[ch].
1846 * Implemented the KILL command to the client. Implemented the
1847 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1848 Affected files lib/silcclient/command[_reply].c and
1849 lib/silcclient/client_notify.c. Implemented the KILL notify
1850 printing in the user inteface.
1852 * Fixed a lot silc_parse_nick memory leaks from the client
1853 library in the file lib/silcclient/command.c.
1855 * Changed the silc_server_send_notify_on_channels's `sender'
1856 argument from SilcSocketConnection to SilcClientEntry to
1857 check the sender as entry and not as connection object and not
1858 to send to the client provided as argument. The affected file
1859 is silcd/packet_send.[ch].
1861 * The notify packets that are destined directly to the client used
1862 to not to be processed by the server. Now changed that and the
1863 server processes all notify packets. After relaying the packet
1864 to the client the notify packet is processed in the server.
1866 * The silc_server_free_client_data now checks whether there is
1867 pending outgoing traffic for the client and purges the data to
1868 the network before removing the client entry.
1870 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1873 an client is killed from the SILC Network. Updated the protocol
1876 Added new function silc_server_send_notify_killed to the
1877 silcd/packet_send.[ch].
1879 * Added function silc_server_packet_relay_notify to relay notify
1880 packets that are destined directly to a client. In this case
1881 the server does not process the notify packets but merely relays
1882 it to the client. Affected file silcd/packet_send.[ch].
1884 Added also silc_server_packet_process_relay_notify to check
1885 whereto relay the notify. Affected file is
1886 silcd/packet_receive.[ch].
1888 * Implemented the KILL command to the server.
1892 * Added the backup schema desgined last fall to the protocol
1893 specs for everyone to see. The specification is in the
1894 *-spec-xx.txt draft and the packet type definitions for the
1895 backup routers is in *-pp-xx.txt draft. Thusly, added also
1896 new packet type SILC_PACKET_CELL_ROUTERS.
1898 * A big security problem in the implementation discovered. The
1899 signoff of an client did not cause new channel key generation
1900 which it of course should've done. The channel keys must be
1901 always re-generated when client leaves (or signoffs) the channel.
1902 The silc_server_remove_from_channels funtion now handles
1903 the channel key re-generation.
1905 * Added `sender' argument to the silc_server_send_notify_on_channels
1906 to not to send the client provided as argument. Affected file
1907 silcd/packet_send.[ch].
1909 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1911 * Implemented OPER and SILCOPER commands into the server and
1914 * Added silc_auth_verify and silc_auth_verify_data to verify
1915 the authentication directly from the authentication payload.
1916 It supports verifying both passphrase and public key based
1917 authentication. Affected file lib/silccore/silcauth.[ch].
1919 * Added `hash' field to the SilcIDListData structure. It is the
1920 hash negotiated in the SKE protocol. Affected file is
1923 * Slight redesigning of the SilcAuthPayload handling routines.
1924 Do not send SilcPKCS but SilcPublicKey as argument.
1926 * Implemented the public key authentication support to the
1927 serverconfig. The public key is loaded from the provided path
1928 and saved as authentication data to void * pointer. Thus,
1929 changed the unsigned char *auth_data to void *auth_data;
1931 * Fixed SHUTDOWN command to send the reply before the server
1932 is shutdown. :) Affected file silcd/command.c.
1934 * Fixed fatal bug in CONNECT command. The hostname was invalid
1935 memory and server crashed. Affected file silcd/command.c.
1937 * Fixed fatal bug in CLOSE command. The server_entry became
1938 invalid but was referenced later in the command. Affected file
1941 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Fixed fatal bug in failure packet handling. Server ignored
1944 the failure and thus crashed when it came.
1948 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1951 that the command may be executed only once in (about) 2 seconds.
1952 The old SILC_CF_LAG flag is same but allows command bursts up
1953 to five before limiting.
1955 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1956 server code. Various commands now includes the CF_LAG_STRICT
1957 flag to disallow any kind of miss-use of the command.
1959 * Fixed the silc_buffer_unformat to not to allocate any data
1960 if the length of the data is zero. It used to allocate the
1961 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1963 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1965 * Changed the format of AdminConnection configuration section
1966 in the server. Added username of the admin to the format.
1967 Affected files silcd/serverconfig.[ch].
1969 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1970 to return admin configuration data by host, username and/or
1973 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1975 * Implemented WHOWAS command to the server. Added the functions:
1977 silc_server_command_whowas_parse,
1978 silc_server_command_whowas_send_reply,
1979 silc_server_command_whowas_from_client and
1980 silc_server_command_whowas_from_server
1982 * Added <Client ID> argument to the WHOWAS command reply. Updated
1983 the protocol specs accordingly.
1985 * Implemented WHOWAS command and command_reply to the client
1988 Implemented the WHOWAS printing on the user interface.
1990 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1992 * Added new argument to the WHOWAS command reply, the real name.
1993 It is an optional argument. Updated the protocol specs.
1995 * Added SilcIDCacheDestructor callback that is registered when
1996 the SilcIDCache is allocated. The callback is called when
1997 an cache entry in the ID Cache expires, or is purged from the
1998 cache. Added into lib/silccore/idcache.[ch].
2000 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2001 to destruct the client entries when the cache entry expires.
2002 Other ID Cache's in server and in the client library ignores
2005 * If the ID Cache entry's `expire' field is zero then the entry
2006 never expires. Added boolean `expire' argument to the
2007 silc_idcache_add function in the lib/silccore/idcache.[ch].
2008 If it is TRUE the default expiry value is used.
2010 * Added silc_server_free_client_data_timeout that is registered
2011 when client disconnects. By default for 5 minutes we preserve
2012 the client entry for history - for WHOWAS command.
2014 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2016 * Added support to the server to enforce that commands are not
2017 executed more than once in 2 seconds. If server receives
2018 commands from client more frequently, timeout is registered
2019 to process the commands. Affected file silcd/command.c.
2020 Added new function silc_server_command_process_timeout.
2022 * Changed NICK_NOTIFY handling in client library to check that
2023 if the client's nickname was changed, so there is no need to
2024 resolve anything from the server.
2026 * Removed error printing from the WHOIS and IDENTIFY commands.
2027 If error occurs then it is ignored silently in the client library.
2028 The application, however, may map the received error to
2029 human readable error string. The application currently maps
2030 the NO_SUCH_NICKNAME error to string.
2032 * Made the command status message public to the application. Moved
2033 them from lib/silcclient/command_reply.c to
2034 lib/silcclient/command_reply.h. The application can map the
2035 received command status to the string with the
2036 silc_client_command_status_message function.
2038 * Added check to the server to check that client's ID is same
2039 as the Source ID in the packet the client sent. They must
2042 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Added dist-bzip hook to the Makefile.am to make bzip2
2045 compressed distributions.
2047 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2049 * Server now enforces the maximum length for the nickname and
2050 the channel as protocol specification dictates. 128 bytes for
2051 nickname and 256 bytes for channel name.
2053 * Moved the WHOIS printing to the application. The client libary
2054 does not print out the WHOIS information anymore, the application
2055 must do it. Renamed silc_client_command_reply_whois_print to
2056 the silc_client_command_reply_whois_save.
2058 The client's idle time is also sent to the application now, and
2059 the idle is shown on screen.
2061 * Added silc_client_command_reply_identify_save to save the
2062 received IDENTIFY entries.
2064 * Do not check for channel private keys in message sending and
2065 reception if the channel does not have the PRIVKEY mode set.
2066 Affected file lib/silclient/client_channel.c.
2068 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2071 just surfaced after chaning the JOIN procedure.
2073 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2075 * Added silc_client_get_clients_by_list to get client entries
2076 from Client ID list, that is returned for example by JOIN
2077 and USERS command replies. The application should use this
2078 function for example when JOIN command reply is received to
2079 resolve the clients already on the channel (library does not
2080 do that anymore as USERS command reply is not used in the JOIN
2081 procedure anymore). Affected files lib/silcclient/silcapi.h and
2082 lib/silcclient/idlist.c.
2084 * JOIN command reply and USERS command reply returns now SilcBuffer
2085 pointers instead of unsigned char pointers when returning
2086 the client list and mode list.
2088 * Added <Client ID> argument to the JOIN command reply, mainly
2089 for the server to identify for which client the command was
2090 originally sent. Updated protocol specs accordingly.
2092 * Added SilcDlist private_key pointer to the SilcChannelEntry
2093 in the client to support the channel private keys. Affected
2094 file is lib/silcclient/idlist.h.
2096 * Added SilcChannelPrivateKey argument to the function
2097 silc_client_send_channel_message so that application can choose
2098 to use specific private ke if it wants to. If it is not provided,
2099 the normal channel key is used, unless private keys are set.
2100 In this case the first (key that was added first) is used
2101 as the encryption key.
2103 * Implemented the support for channel private key handling.
2104 Implemented the following functions:
2106 silc_client_add_channel_private_key,
2107 silc_client_del_channel_private_keys,
2108 silc_client_del_channel_private_key,
2109 silc_client_list_channel_private_keys and
2110 silc_client_free_channel_private_keys
2112 Affected file lib/silcclient/client_channel.c.
2114 * Added the support for the private keys in the channel message
2115 sending and encryption and in the message reception and
2116 decryption. Affected funtions are
2117 silc_client_send_channel_message and silc_client_channel_message.
2119 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2121 * Added SKE's key verify callback to the client library's
2122 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2124 * Removed the statement that server (or router) must send USERS
2125 command reply when joining to the channel so that the client
2126 knows who are on the channel. Instead, the client list and
2127 client's mode list is now sent in the JOIN command reply to the
2128 client who joined channel. This is better solution.
2130 * Added function silc_server_get_users_on_channel and function
2131 silc_server_save_users_on_channel to the silcd/server.[ch].
2133 * Removed function silc_server_command_send_users from the
2136 * Do not show topic on the client library anymore. The topic is
2137 sent in the command reply notify to the application and the
2138 application must show the topic now.
2140 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2142 * Added client searching by nickname hash into the IDENTIFY and
2143 WHOIS commands in the server as they were clearly missing from
2144 them. Affected file is silcd/command.c.
2146 * Fixed a bug in private message receiving in the client library.
2147 The remote ID was freed and it wasn't supposed, now it is
2150 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2152 * Minor fix to the channel payload; allocate the data area, as it
2153 needs to be of specific length.
2155 * If the key agreement port is zero then the operating
2156 system will define the bound port. Affected files are
2157 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2159 * Added new function silc_channel_payload_decrypt into the file
2160 lib/silccore/silcchannel.[ch].
2162 * Moved the channel message etc, check from silc_packet_decrypt
2163 to applications. The library calls now a generic
2164 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2165 when the packet is either normal or special. This was done to
2166 allow more wide range of checking that was not allowed when
2167 the code was in library. Now applications can do virtually any
2168 checks to the packet and return to the library the decision how
2169 the packet should be processed. Affected files are
2170 lib/silccore/silcpacket.[ch].
2172 Added silc_server_packet_decrypt_check to the server and
2173 silc_client_packet_decrypt_check to the client library.
2175 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2176 to send with specified source and destination information.
2178 * Channel message delivery between routers was broken after the
2179 channel key distribution was fixed earlier. The channel key
2180 was used be to distributed to other routers as well which is not
2181 allowed by the protocol. Now this is fixed and channel keys
2182 really are cell specific and the channel message delivery between
2183 routers comply with the protocol specification.
2185 * Fixed various commands in server to check also the global list
2186 for the channel entry and not just the local list. The affected
2187 file silcd/command.c.
2189 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Added assert()s to buffer formatting and unformatting routines
2192 to assert (if --enable-debug) when error occurs. Affected
2193 file: lib/silcutil/silcbuffmt.c.
2195 * Changed to auto-reconnect to check whether the remote host is
2196 router and register the re-connect timeout if it is. It used
2197 to check that whether we are normal server, but router must do
2198 auto-reconnect with another router as well. Affected file
2201 * Removed the [<key len>] option from CMODE command as the cipher
2202 name decides the key length, nowadays. See the defined ciphers
2203 from the protocol specification.
2205 * Added [<hmac>] option to the CMODE command to define the HMAC
2206 for the channel. Added SILC_CMODE_HMAC channel mode.
2208 * Added [<hmac>] option for the JOIN command so that user can
2209 select which HMAC is used to compute the MACs of the channel
2212 * Added Hmac field to the Channel Message Payload. The integrity
2213 of plaintext channel messages are now protected by computing
2214 MAC of the message and attaching the MAC to the payload. The
2215 MAC is encrypted. Now, it is clear that this causes some
2216 overhead to the size of the packet but rationale for this is that
2217 now the receiver can verify whether the channel message decrypted
2218 correctly and also when private keys are set for the channel the
2219 receiver can decrypt the packet with several keys and check from
2220 the MAC which key decrypted the message correctly.
2222 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2223 lib/silccrypt/silccipher.[ch].
2225 * Added silc_hash_len to return the digest length into the
2226 lib/silcrypt/silchash.[ch].
2228 * Rewrote parts of Silc Channel Payload interface in the
2229 lib/silccore/silcchannel.[ch]. The encode function now also
2230 encrypts the packet and parse function decrypts it.
2232 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2234 * Fixed a minor formatting bug in the SKE's key material processing.
2235 It actually might have processed the keys wrong way resulting
2238 * Redefined the mandatory HMAC algorithms and added new algorithms.
2239 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2240 and hmac-md5 truncated to 96 bits. The mandatory is now
2241 hmac-sha1-96. Rest are optional (including the one that used
2242 to be mandatory). Rationale for this is that the truncated HMAC
2243 length is sufficient from security point of view and can actually
2244 make the attack against the HMAC harder. Also, the truncated
2245 HMAC causes less overhead to the packets. See the RFC2104 for
2248 * Added new [hmac] configuration section. The SKE used to use
2249 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2250 is of course wrong. The official names that must be proposed in
2251 the SKE are the ones defined in the protocol specification
2252 (hmac-sha1-96 for example). The user can configure any hmac
2253 using any hash function configured in the [hash] section. At
2254 least, the mandatory must be configured.
2256 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2258 * Added HMAC list to the SKE proposal list. It has now both
2259 hash algorithm list and HMAC list. This makes the protocol
2260 incompatible with previous versions. The SKE now seems to work
2261 the way it is supposed to work, for the first time actually.
2263 * Defined plain Hash algorithms to the protocol specification.
2266 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2268 * Implemented support for key agreement packets into the server.
2269 Added functions silc_server_key_agreement and
2270 silc_server_send_key_agreement. Other than these functions,
2271 server has nothing to do with this packet.
2273 * Added support for private message key packets into the server.
2274 Added functions silc_server_private_message_key and
2275 silc_server_send_private_message_key.
2279 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2280 called in the protocol's final callback instead in the END
2281 protocol state. This makes a little more sense and in the same
2282 time in client we can use the same protocol routines for normal
2283 key exchange and to key agreement packet handling as well.
2285 * Added to both client's and server's KE protocol context the
2286 SilcSKEKeyMaterial pointer to save the key material. We will
2287 bring the key material to the protocol's final callback by doing
2288 this. The final callback must free the key material.
2290 * Added SKE's packet_send callback into client's KE protocol
2291 context so that the caller can choose what packet sending function
2292 is used. This way we can use different packet sending when
2293 doing normal SKE when doing key agreement packet handling (in
2294 the key agreement packet handling we do not want to encrypt
2297 * Implemented the responder side of the key agreement routines
2298 in the client. The client can now bind to specified port and
2299 accept incoming key negotiation. The key material is passed
2300 to the application after the protocol is over.
2302 * Implemented the processing of incoming Key Agreement packet
2303 in the client. Added function silc_client_key_agreement to
2306 * Implemented the intiator side of the key agreement routines
2307 in the client. The client can now initiate key agreement with
2308 another remote client. The key material is passed to the
2309 application after the protocol is over.
2311 * Created client_keyagr.c to include all the key agreement
2314 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2315 SILC_TASK_CALLBACK except that it is not static.
2317 * Created client_notify.c and moved the Notify packet handling
2318 from the client.[ch] into that file.
2320 * Created client_prvmsg.c and moved all private message and
2321 private message key routines from the client.[ch] into that file.
2323 * Create client_channel.c and moved all channel message and
2324 channel private key routines from the client.[ch] into that file.
2326 * Changed silc_client_get_client_by_id_resolve to resolve with
2327 WHOIS command instead of IDENTIFY command, in the file
2328 lib/silclient/idlist.c.
2330 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Implemented the SKE's responder side to the Client library.
2334 * When FAILURE is received to the protocol do not trust it
2335 blindly. Register a timeout to wait whether the remote closes
2336 the connection as it should do it, only after that process the
2337 actual failure. This was changed to both client and server.
2339 * Added client_internal.h to include some of the structures
2340 there instead of client.h in lib/silcclient/.
2342 * Added function silc_task_unregister_by_callback to unregister
2343 timeouts by the callback function.
2345 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Some "Incomplete WHOIS info" errors has been appearing on the
2348 log files. Took away the entry->userinfo check from WHOIS
2349 reply sending. The entry->userinfo is now " " if client did not
2350 provide one. I thought this was fixed earlier but something
2351 is wrong still. Let's see if the error still appears.
2353 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * Fixed a minor bug in the login when the channel key is
2356 re-generated in the server. It used to generate the key in
2357 wrong order and thus caused problems in the channel traffic.
2359 * Fixed a minor bug in channel key distsribution after
2360 KICK command. The key was not sent to the router even though
2363 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2365 * Added silc_ske_process_key_material_data as generic routine
2366 to process any key material as the SILC protocol dictates. The
2367 function is used by the actual SKE library but can be used by
2368 applications as well. This relates to the private message keys
2369 and the channel private keys since they must be processed the
2370 same way the normal SILC session keys. The protocol dictates
2371 this. Affected files: lib/silcske/silcske.[ch].
2373 Added also silc_ske_free_key_material to free the
2374 SilcSKEKeyMaterial structure.
2376 * Defined silc_cipher_set_key function to set the key for
2377 cipher without using the object's method function. The affected
2378 files: lib/silccrypt/silccipher.[ch].
2380 * Implemented silc silc_client_add_private_message_key,
2381 silc_client_add_private_message_key_ske,
2382 silc_client_del_private_message_key,
2383 silc_client_list_private_message_keys and
2384 silc_client_free_private_message_keys functions in the
2387 Added functions silc_client_send_private_message_key to send
2388 the Private Message Key payload and silc_client_private_message_key
2389 to handle incoming Private Message Key payload.
2391 * Added Cipher field to the Private Message Key payload to set
2392 the cipher to be used. If ignored, the default cipher defined
2393 in the SILC protocol (aes-256-cbc) is used.
2395 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Removed lib/silcclient/ops.h file.
2399 Redefined parts of the SILC Client Library API. Created new
2400 file silcapi.h that deprecates the ops.h file and defines the
2401 published Client Library API. Defined also private message key
2402 API and channel private key API into the file.
2404 This is the file that the application must include from the
2405 SILC Client Library. Other files need not be included by
2406 the application anymore.
2408 * Added new key_agreement client operation callback and also
2409 defined the Key Agreement library API for the application.
2411 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2413 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2414 is used by clients to request key negotiation between another
2415 client in the SILC network. If the negotiation is started it
2416 is performed using the SKE protocol. The result of the
2417 negotiation, the secret key material, can be used for example
2418 as private message key.
2420 Implemented the Key Agreement payload into the files
2421 lib/silccore/silauth.[ch].
2423 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2425 * Redefined ciphers for the SILC protocol. Added some new ciphers
2426 and defined the key lengths for the algorithms. Changed the
2427 code accordingly. The default key length is now 256 bits.
2429 * Fixed SKE key distribution function silc_ske_process_key_material
2430 when the key length is more than 128 bits. The default key
2431 length in SILC is now 256 bits.
2433 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2434 to indicate unsupported algorithm.
2436 * Renamed rijndael.c to aes.c and all functions as well.
2438 * Fixed a long standing channel key setting bug in client library.
2439 Weird that it has never surfaced before.
2441 * Fixed bug in channel deletion. If the entire channel is removed
2442 then it must also delete the references of the channel entry
2443 from the client's channel list as the client's channel entry and
2444 the channel's client entry share same memory.
2446 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Implemented CONNECT and SHUTDOWN commands in the client.
2450 * Implemented CLOSE command to the client.
2452 * Added the function silc_idlist_find_server_by_name into the
2453 files silcd/idlist.[ch].
2455 Added the function silc_idlist_find_server_by_conn into the
2456 files silcd/idlist.[ch].
2458 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * DIE command was renamed to SHUTDOWN. Updated the both code
2463 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2464 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2466 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2469 * Added function silc_server_create_connection function to create
2470 connection to remote router. My server implementation actually
2471 does not allow router to connect to normal server (it expects
2472 that normal server always initiates the connection to the router)
2473 so the CONNECT command is only good for connecting to another
2476 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2479 or some other client was kicked from the channel.
2481 Implemented the handling of the notify type to both client
2484 Implemented silc_server_send_notify_kicked to send the KICKED
2485 notify. It is used to send it to the server's primary router.
2487 * Implemented the KICK command into server and client.
2489 * Added `query' argument to the silc_idlist_get_client function
2490 to indicate whether to query the client from server or not if
2493 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2494 to indicate that the client is not channel founder.
2498 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2500 * Removed the rng context from SilcPacketContext structure and
2501 changed that the packet routine uses the Global RNG API.
2503 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2505 * Added support for quit message that client can "leave" on the
2506 channel when it quits the SILC. It is ditributed inside the
2507 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2509 Added silc_server_free_client_data that will take the
2510 signoff message as argument.
2512 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2514 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * Updated parts of the protocol specification to keep it up
2519 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2522 payloads in one packet.
2524 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2525 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2526 use now the new List flag.
2528 * Also deprecated the following packet types: REPLACE_ID,
2529 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2531 * Added list support for Notify packet in server.
2533 * Added silc_server_send_notify_channel_change to send the
2534 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2535 the silc_server_send_replace_id.
2537 * Added silc_server_send_notify_nick_change to send the
2538 NICK_CHANGE notify type. Deprecates the function
2539 silc_server_send_replace_id.
2541 * Added silc_server_send_notify_join to send the JOIN notify type.
2542 Deprecates the function silc_server_send_new_channel_user.
2544 * Added silc_server_send_notify_leave to send LEAVE notify type.
2545 Deprecates the function silc_server_send_remove_channel_user.
2547 * Added silc_server_send_notify_cmode and
2548 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2549 types. Deprecates the silc_server_send_set_mode function.
2551 * Added SERVER_SIGNOFF notify type to indicate that server has
2552 quit. This means that all clients on the channel from that
2553 server will drop. This can be also used when netsplit happens.
2555 Deprecated REMOVE_ID packet type since it is not needed anymore
2558 Added silc_server_send_notify_server_signoff to send the
2559 SERVER_SIGNOFF notify type. Deprecates the function
2560 silc_server_send_remove_id.
2562 Added also silc_server_send_notify_signoff to send the
2563 SIGNOFF notify type.
2565 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2566 SILC protocol from this day on. Changed the protocol
2567 specification as well.
2569 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2570 notify type. It is used between routers to notify about
2571 topic changes on a channel.
2573 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2576 * Partly updated the protocol specification to comply with the
2577 changes now made. It is still though a bit outdated.
2579 * The JOIN notify type now takes one extra argument <Channel ID>.
2580 The packet used to be destined to the channel but now the
2581 JOIN type may be sent as list thus it is impossible to
2582 destine it to any specific channel. By adding this argument
2583 it is again possible.
2585 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * Added CREDITS file. The CHANGES and CREDITS file will appear
2588 in the distribution as well.
2590 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2592 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2593 types in the server's silcd/packet_receive.c.
2595 * Implemented CMODE and CUMODE to work in router environment.
2597 * Fixed minor encoding and decoding buglet from the
2598 lib/silccore/silcmode.c.
2600 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2603 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2605 * Changed all SilcConfigServer* and silc_config_server* to
2606 SilcServerConfig* and silc_server_config*, respectively.
2609 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2611 * Associated the ID (client or server ID) to the Authentication
2612 Payload to avoid any possibility of forging. Updated the
2613 protocol specification and the code accordingly.
2615 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * The RSA key length is now save to the RsaKey context in the
2618 key generation process in lib/silccrypt/rsa.c. The key length
2619 is now used to figure out the maximum size of the block allowed
2620 to be encrypted/signed.
2622 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2623 is equivalent to the silc_mp_mp2bin but does not allocate any
2626 * Changed silc_mp_mp2bin API to take length argument. If it is
2627 non-zero then the buffer is allocated that large. If zero, then
2628 the size is approximated using silc_mp_sizeinbase, which however
2631 * Created Global RNG API which is global RNG that application can
2632 initialize. After initializing, any routine anywhere in the
2633 code (including library) can use RNG without allocating a new
2634 RNG object. This was done to allow this sort of use of the
2635 RNG in code that has no chance to allocate RNG object. All
2636 applications currently allocate this and many routines in the
2637 library use this. Affected file lib/silccrypt/silcrng.[ch].
2639 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2640 it to use the Global RNG API.
2642 * Defined Authentication Payload into protocol specification that
2643 is used during SILC session to authenticate entities. It is
2644 used for example by client to authenticate itself to the server
2645 to obtain server operator privileges.
2647 Implemented this payload into the lib/silccore/silcauth.[ch].
2648 Implemented also routines for public key based authentication
2649 as the new protocol specification dictates.
2651 Moved definitions of different authentication methods from
2652 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2654 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2655 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2656 silc_pkcs_verify_with_hash functions into the file
2657 lib/silccrypt/silcpkcs.[ch].
2659 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * The client entry's userinfo pointer must be always valid.
2662 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2663 will fail since it requires the userinfo. Now, the userinfo
2664 is allocated as "" if actual userinfo does not exist. Actually,
2665 it must exist and it is totally Ok to drop client connections
2666 that does not announce the userinfo. However, we will make
2667 this workaround for now.
2669 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2670 to return the remote port by socket.
2672 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2674 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2675 SILC_SERVER_PENDING_EXEC and added an new macro
2676 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2677 data or when error occurs while processing the pending command.
2679 Added new argument `destructor' into silc_server_command_pending
2680 and to the SilcServerCommandPending object. This destructor is
2681 now called after calling the pending callback or if error occurs
2682 immediately. If error occurs the actual pending callback won't
2683 be called at all - only the destructor. The destructor may be
2684 NULL if destructor is not needed.
2686 All this applies for client library code as well. Similar
2687 changes were made there as well for the pending commands.
2689 In the client, the application must now allocate the
2690 SilcClientCommandContext with the silc_client_command_alloc
2693 * Added reference counter to the SilcServerCommandContext. Added
2694 function silc_server_command_alloc and silc_server_command_dup
2697 Same type of functions added to the client library for the same
2700 * Removed the cmd_ident from IDListData away since it is now
2701 global for all connections. It is the command identifier used
2702 in command sending and with pending commands. The affected file
2705 * Added reference counter to the SilcSocketConnection objecet to
2706 indicate the usage count of the object. The object won't be
2707 freed untill the reference counter hits zero. Currently only
2708 server uses this, and client ignores it. The client must be
2709 set to use this too later. The affected files are
2710 lib/silccore/silcsockconn.[ch]. Added also the function
2711 silc_socket_dup to increase the reference counter.
2713 This was mainly added because it is possible that the socket
2714 is removed underneath of pending command or other async
2715 operation. Now it won't be free'd and proper DISCONNECTING
2716 flags, etc. can be set to avoid sending data to connection that
2717 is not valid anymore.
2719 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2720 the connection. After that it sets SILC_SET_DISCONNECTED.
2721 It is, however, possible that the socket data is not still freed.
2722 The silc_server_packet_process now checks that data is not
2723 read or written to connection that is DISCONNECTED. The socket
2724 get's freed when the reference counter hits zero.
2726 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Changed the client operation API: channel_message operation's
2729 `sender' is now the client entry of the sender, not the nickname
2730 and the `channel' is the channel entry, not the channel name.
2732 In the private_message operation the `sender' is now also the
2733 client entry of the sender not the nickname.
2735 Affected file is lib/silcclient/ops.h and all applications
2736 using the client operations.
2738 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2740 * Moved the calling of ops->connect() from connect_to_server_final
2741 into receive_new_id functin since that is the point when the
2742 client is actually allowed to send traffic to network. The
2743 affected file is lib/silcclient/client.c.
2745 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2748 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2749 (if needs broadcasting) instead of broadcasting the packets one
2750 by one which would make a burst in the network traffic.
2752 * Added `broadcast' argument to the functions in silcd/server.[ch]
2753 silc_server_create_new_channel[_with_id] to indicate whether
2754 to send New Channel packet to primary router.
2756 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Added new function into the silcd/server.[ch] files:
2759 silc_server_create_new_channel_with_id to create new channel with
2760 already existing Channel ID.
2762 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2763 lib/silccore/silcpacket.h. This packet is used t send list of
2764 Set Mode payloads inside one packet. Server uses this to set
2765 the modes for the channels and clients on those channels, that it
2766 announced to the router when it connected to it. The protocol
2767 specification has been updated accordingly.
2769 * The silc_server_new_channel did not handle the packet coming
2770 from normal server as it normally does not send that. However,
2771 when it announces its channels it does send it. Implemented
2772 the support for that.
2774 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2775 into the file lib/silccore/id.h.
2777 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2779 * Fixed memory leaks in the functions silc_idlist_del_client,
2780 silc_idlist_del_channel and silc_idlist_del_server in the file
2781 silcd/idlist.c. All of those leaked like a sieve.
2783 * Fixed some small memory leaks in the client's function
2784 silc_client_notify_by_server.
2786 * Added functions into silcd/server.c: silc_server_announce_clients,
2787 silc_server_announce_channels and silc_server_announce_server.
2788 These functions are used by normal and router server to announce
2789 to its primary router about clients, channels and servers (when
2790 router) that we own. This is done after we've connected to the
2793 These functions effectively implements the following packet types:
2794 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2795 and SILC_PACKET_NEW_ID_LIST.
2797 * Added new functions into the silcd/packet_receive.[ch]:
2798 silc_server_new_id_list, silc_server_new_channel_list and
2799 silc_server_new_channel_user_list to handle the incoming
2800 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2802 * Added support of changing Channel ID in the function
2803 silc_server_replace_id. If the server that announces a channel
2804 to the router already exists in the router (with same name but
2805 with different Channel ID), router is responsible to send
2806 Replace ID packet to the server and force the server to change
2807 the Channel ID to the one router has.
2809 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2810 client that the Channel ID has been changed by the router. The
2811 normal server sends this to the client. Client must start using
2812 the new Channel ID as the channel's ID.
2814 Implemented handling of this new type into lib/silcclient/client.c
2815 into the function silc_client_notify_by_server.
2817 * Added new function silc_idlist_replace_channel_id into the files
2818 silcd/idlist.[ch] to replace the Channel ID.
2820 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2822 * Call silc_server_command_identify_check always when processing
2823 the IDENTIFY command in silcd/command.c
2825 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2827 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2828 send keepalive packets. The packet can be sent by clients,
2829 servers and routers.
2831 Added function silc_socket_set_heartbeat into the file
2832 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2833 If not set, the heartbeat is not performed. The actual
2834 heartbeat is implemented in the low level socket connection
2835 library. However, application is responsible of actually
2838 Added silc_server_send_heartbeat to send the actual heartbeat
2839 packet into silcd/packet_send.[ch]. Server now performs
2840 keepalive with all connections.
2842 * Added silc_task_get_first function into lib/silcutil/silctask.c
2843 to return the timeout task with shortest timeout. There was a bug
2844 in task unregistration that caused problems. TODO has been
2845 updated to include that task system must be rewritten.
2847 * The client library will now resolve the client information when
2848 receiving JOIN notify from server for client that we know but
2849 have incomplete information.
2851 * Rewrote parts of silc_server_remove_from_channels and
2852 silc_server_remove_from_one_channel as they did not remove the
2853 channel in some circumstances even though they should've.
2855 * Encryption problem encountered in server:
2857 The LEAVE command used to send the Channel Key packet to the
2858 router immediately after generating it. However, the code
2859 had earlier sent Remove Channel user packet but not immediately,
2860 ie. it was put to queue. The order of packets in the router
2861 was that Channel Key packet was first and Remove Channel User
2862 packet was second, even though they were encrypted in the
2863 reverse order. For this reason, MAC check failed. Now, this
2864 is fixed by not sending the Channel Key packet immediately but
2865 putting it to queue. However, this is more fundamental problem:
2866 packets that are in queue should actually not be encrypted
2867 because packets that are sent immediately gets encrypted
2868 actually with wrong IV (and thus MAC check fails). So, packets
2869 that are in queue should be encrypted when they are sent to
2870 the wire and not when they put to the queue.
2872 However, the problem is that the current system has not been
2873 designed to work that way. Instead, the packet is encrypted
2874 as soon as possible and left to the queue. The queue is then
2875 just purged into wire. There won't be any fixes for this
2876 any time soon. So, the current semantic for packet sending
2879 o If you send packet to remote host and do not force the send
2880 (the packet will be in queue) then all subsequent packets to the
2881 same remote host must also be put to the queue. Only after the
2882 queue has been purged is it safe again to force the packet
2885 o If you send all packets immediately then it safe to send
2886 any of subsequent packets through the queue, however, after
2887 the first packet is put to queue then any subsequent packets
2888 must also be put to the queue.
2890 Follow these rules and everything works fine.
2892 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Added new function silc_server_remove_clients_by_server to
2895 remove all client entries from ID list when the server connection
2896 is lost. In this case it is also important to invalidate all
2897 client entires as they hold the invalid server entry. This
2898 fixes fatal bug when server has lost connection and will reconnect
2901 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Made some sanity checks to silc_server_daemonise like to check
2904 whether the requested user and group actually exists.
2906 * Added sanity check to SKE's silc_ske_responder_finish to check
2907 that the public and private key actually is valid.
2909 * Invalidate the client's nickname when receiving Replace ID
2910 packet and the Client ID is being replaced. This means that the
2911 server will query the nickname if someone needs it (client)
2914 * Sort the ID Cache in client library when the ID Cache data
2915 has changed (needs sorting).
2917 * Do not allow for SILC client to create several connections to
2918 several servers. The client does not support windows right now
2919 and generating multiple connections causes weird behaviour.
2921 Irssi-silc client does support windows and can handle several
2922 connections without problems, see: www.irssi.org and SILC plugin.
2924 * Fixed some places where client was added to the IDList. The
2925 rule of thumb is following (in order to get everything right):
2926 If the client is directly connected local client then the
2927 `connection' argument must be set and `router' argument must be
2928 NULL to silc_idlist_add_client function. If the client is not
2929 directly connected client then the `router' argument must
2930 bet set and the `connection' argument must be NULL to the
2931 silc_idlist_add_client function.
2933 * The funtion silc_server_packet_send_local_channel actually did
2934 not check whether the client was locally connected or not. It
2935 does that now. Fixed a bug related to LEAVE command.
2937 * Fixed Remove Channel User payload parsing bug in server's
2938 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2940 * The server's silc_server_save_channel_key now checks also the
2941 global ID list for the channel as it might not be in the local
2942 list. Fixed a bug related to LEAVE command.
2944 * Is this the end of the [<unknown>] buglet that has been lurking
2945 around for a long time? A little for loop fix in server's
2946 silc_server_command_whois_parse that is used by both IDENTIFY
2947 and WHOIS command. At least, this was a clear bug and a cause
2948 of one type of [<unknown>] buglet.
2950 * WHOIS and IDENTIFY commands call the function
2951 silc_server_command_[whois/identify]_check function even if
2952 we are not router server.
2954 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2956 * Added --with-gmp configuration option. If set the GMP
2957 is always compiled in the SILC source tree. If not set then
2958 it is checked whether the system has the GMP3 installed. If
2959 it has then the GMP won't be compiled (the system's headers
2960 and library is used), if it doesn't have it then the GMP is
2961 compiled in the SILC source tree.
2963 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Changed RSA private exponent generation to what PKCS #1
2966 suggests. We try to find the smallest possible d by doing
2967 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2968 not security fix but optimization.
2970 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2972 * Added new config entry [Identity] to fork the server and run
2973 it as specific user and group. A patch from Bostik.
2975 * Imported Dotconf configuration library into lib/dotconf.
2976 This will be used to create the SILC configuration files later.
2977 It will appear in the distsribution after this commit.
2979 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2981 * A big code auditing weekend happening. Auditing code for
2982 obvious mistakes, bugs and errors. Also, removing any code
2985 Removed files for being obsolete:
2987 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2988 inline in the file lib/silcutil/silcbuffer.h)
2990 o lib/silcutil/silcbufutil.c (the header has inline versions)
2992 Changed code to fix possible error conditions:
2994 o The buffer formatting routines now check that the destination
2995 buffer really has enough space to add the data. This applies for
2996 both buffer formatting and unformatting
2997 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2998 unformatting was changed to accomodate following rules:
2999 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3000 sent to the function while XXX_*STRING will not allocate or copy
3001 the data into the buffer. Instead it sets the pointer from the
3002 buffer into the pointer sent as argument (XXX_*STRING used to
3003 require that the pointer must be allocated already). This change
3004 makes this whole thing a bit more consistent and more optimized
3005 (note that the data returned in the unformatting with XXX_*STRING
3006 must not be freed now). The routines return now -1 on error.
3008 o Tried to find all code that use buffer_format and buffer_unformat
3009 and added return value checking to prevent formatting and
3010 especially unformatting errors and possible subsequent fatal
3013 o Changed ske->x and ske->KEY to mallocated pointers in
3014 lib/silcske/silcske.h. Fixed possible data and memory leak.
3016 o Added return value checking to all *_parse* functions. Fixed
3017 many memory leaks as well.
3019 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3020 so that buffer overflows would not happen. All code now also
3021 checks the return value as it can fail.
3023 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3025 * Added reconnection support to server if the normal server looses
3026 its connection to the router (for example if router is rebooted).
3027 The server performs normal reconnection strategy implemented
3028 to the server. Affected file silcd/server.c.
3030 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3032 * Added new packet type SILC_PACKET_SET_MODE that is used to
3033 distribute the information about changed modes (for clients,
3034 channels and clients channel modes) to all routers in the
3035 network. Updated the protocol specification accordingly.
3037 Added functions into silcd/packet_send.c and
3038 silcd/packet_receive.c: silc_server_send_set_mode,
3039 silc_server_set_mode.
3041 Added new files silcmode.[ch] into lib/silccore that implements
3042 the encoding and decoding of Set Mode Payload. Added new type
3043 SilcSetModePayload. Moved the definitions of different modes
3044 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3046 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Oops, a little mistake in server's connection authentication
3049 protocol. The protocol is not ended with FAILURE but with
3050 SUCCESS if the authentication is Ok. :) Affected file is
3053 * Implemented NICK_CHANGE notify handling in server in the file
3054 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3055 the local clients on the channel. After the changing nickname
3056 in router environment snhould work and the [<unknown>] nickname
3057 should appear no more.
3059 The silc_server_replace_id function that receives the Replace ID
3060 payload now sends the NICK_CHANGE notify type also in the file
3061 silcd/packet_receive.c
3063 * Changed WHOIS and IDENTIFY command to support the maximum amount
3064 of arguments defined in protocol specs (3328 arguments). This
3065 fixed a bug that caused problems when there were more than three
3068 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3070 * Added extra parameter, command identifier, to the
3071 silc_client_send_command so that explicit command identifier
3074 Changed that ID list routines uses specific command identifier
3075 when sending WHOIS/IDENTIFY requests to the server so that they
3076 can be identified when the reply comes back.
3078 Affected files lib/silcclient/command.[ch],
3079 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3081 * Added `sender' argument to silc_server_packet_send_to_channel
3082 to indicaet the sender who originally sent the packet to us
3083 that we are now re-sending. Ignored if NULL. Affected file
3084 silcd/packet_send.[ch].
3086 * Added some server statistics support in silcd/server_internal.h
3087 SilcServerStatistics structure and around the server code. Also
3088 send some nice statistics information when client is connecting
3091 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Fixed channel ID decoding in server's JOIN command reply in
3094 silcd/command_reply.c
3096 * Fixed braodcasting of replace ID payload to not to send it if
3097 we are standalone server in silcd/packet_receive.c.
3099 * Fixed all channel message sending routines to not to send
3100 packets to clients that has router set, since they are routed
3101 separately in the same function earlier. Affects file
3102 silcd/packet_send.c and all channel packet sending functions.
3104 * In USERS reply, res_argv[i] are not allocated, the table
3105 is allocated. Thus changed that free the table, not its
3108 * In server's whois_check and identify_check if the client is
3109 locally connected do not send any WHOIS commands - they are not
3112 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Fixed some minor bugs in client when sending WHOIS command. The
3115 arguments was in wrong order.
3117 * Removed statis function add_to_channel from server in
3118 silcd/command.c that was previously used with the joining but
3121 * Tested USERS command in router environment successfully with two
3122 routers, two servers and two clients.
3124 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3126 * Reorganized the USERS command and command reply in client library
3127 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3128 When the command is given by user we register a pending command
3129 callback that will reprocess the command after the reply has been
3130 received from the server. When reprocessing the packet we then
3131 display the information. Thus, the USERS information is displayed
3132 now in the command callback instead of in the command reply
3133 callback. The processing of the command is same as previously
3134 when server has sent the command reply in the JOINing process.
3136 * Added to USERS command in silcd/command_reply.c to join the client,
3137 we didn't use to know about, to the channel after we've created
3138 a client entry for it. Also, for clienet we did know already still
3139 check whether it is on the channel or not and add it if not.
3141 * Removed silc_server_command_join_notify as the function and its
3144 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Changed the client's pending command handling to the same as the
3147 server's pending command handling. It is also now possible to
3148 execute command reply functions from other command reply
3149 function as the function callbacks for commands and command
3150 replies are one and same. The pending commands are not static
3151 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3152 in client connection context. Thus, pending commands are server
3153 connection specific as it is convenient.
3155 Changed the function silc_client_command_pending and
3156 silc_client_command_pending_del and added new function
3157 silc_client_command_pending_check. Removed the
3158 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3161 * Added cmd_ident, current command identifier, to the client
3162 connection context in lib/silcclient/client.h to keep track on
3163 command identifiers used in command sending. Client's command reply
3164 function handling now supports the mandatory command identifiers.
3166 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3167 funtions in client to fully support pending command callbacks.
3169 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3170 as one of the arguments to the application in the command reply
3173 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3174 before first releasing SILC but came back. Now it is removed again
3175 and should come back nomore. The FORWARDED flag was used only
3176 by the JOINing procedure by forwarding the command packet to router.
3177 Now, the JOINing procedure has been changed to more generic (due
3178 to various router environment issues) and FORWARDED is not needed
3179 anymore for anything. The protocol specification is yet to be
3182 Now, removed silc_server_packet_forward from server and the flag
3183 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3185 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Renamed NAMES command to USERS command. The NAMES was named that
3188 due to historical reasons. Now it is renamed. Also, rewrote
3189 parts of the USERS command. The nickname list is not sent anymore
3190 by the server. Only Client ID and mode lists are sent in the USERS
3191 command. Changed this also to the protocol specification.
3193 The client now resolves the names and stuff after it receives
3194 the USERS list from the server when joining to the channel.
3196 * WHOIS and IDENTIFY commands has been changed to support multiple
3197 Client ID's per command. One can now search for multiple users
3198 in the network by sending only one WHOIS or IDENTIFY command.
3199 Changed the code and the protocol specifications.
3201 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3202 uses silc_server_command_whois_parse to parse the request. */
3204 * If normal server, do not parse the WHOIS and IDENTIFY requests
3205 before sending it to the router. Saves some time.
3207 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3209 * Fixed JOIN command on client library. Wrong number of arguments
3210 used to crash the client.
3212 * Added silc_server_channel_has_global function to check whether
3213 channel has global users or not.
3215 * Added silc_server_channel_has_local function to check whether channel
3216 has locally connected clients on the channel.
3218 * The silc_server_remove_from_one_channel now checks whether the
3219 channel has global users or not after given client was removed from
3220 the channel. It also checks whether the channel has local clients
3221 on the channel anymore. If it does not have then the channel entry
3222 is removed as it is not needed anymore.
3224 * The silc_server_notify now checks on JOIN notify whether the joining
3225 client is one of locally connected or global. If it is global then
3226 the channel has now global users on the channel and that is marked
3227 to the channel entry. Also, it now saves the global client to
3228 global list who is joining and JOINs it to the channel. This is
3229 for normal server, that is.
3231 Changed silc_server_send_notify_on_channel,
3232 silc_server_packet_relay_to_channel and
3233 silc_server_packet_send_to_channel check if we are normal server
3234 and client has router set (ie. global client) do not send the
3235 message to that client, as it is already routed to our router.
3237 * Implemented LEAVE notify type handling in silc_server_notify
3240 * Tested LEAVE command in router environment successfully. Tested
3241 with two routers, two servers and two clients.
3245 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3247 * Implemented SIGNOFF notify type handling in silc_server_notify
3250 * silc_server_remove_id now removes the client entry from all channels
3251 it has joined and thusly sends SIGNOFF notify type.
3253 * Rewrote the NAMES list generation in server by removing two excess
3254 loops. The lists are created now inside one loop.
3256 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * silc_server_remove_channel_user checks now also global list
3259 for channel and client.
3261 * silc_server_new_channel_user checks now both local and global
3262 list for channel and client. Fixed a bug in client id decoding.
3263 Used to decode wrong buffer.
3265 * silc_server_channel_message checks now both local and global
3266 list for channel entry.
3268 * Tested channel joining (hence JOIN) in router environment
3269 successfully. Tested with two routers, two servers and two
3272 * Tested channel message sending in router environment successfully.
3274 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * Added silc_server_save_channel_key into server.[ch] to save the
3277 received channel key in Channel Key payload processing. It is
3278 also used in JOIN command reply handling.
3280 Equivalent function silc_client_save_channel_key added into
3281 client.[ch] into client library.
3283 * Changed JOIN command reply to send information whether the channel
3284 was created or not (is existing already) and the channel key
3285 payload. Changed protocol specs accordingly.
3287 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3288 the request was sent by ID and not by nickname. Crashed on
3291 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3293 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3294 now correctly save the received data.
3296 * silc_server_free_sock_user_data now notifies routers in the
3297 network about entities leaving the network.
3299 At the same time implemented functions silc_server_remove_id
3300 and silc_server_send_remove_id to receive and send REMOVE_ID
3301 packets. The packet is used to notify routers in the network
3302 about leaving entities. The ID removed will become invalid in
3305 * Added function silc_idlist_del_server into server. Removes and
3306 free's server entry from ID list.
3308 * silc_server_private_message function now checks, if we are router,
3309 that the destination ID really is valid ID, naturally.
3311 * In router when NEW_ID packet is received (for new client) the
3312 hash of the Client ID is saved in the ID Cache but the
3313 client->nickname is set to NULL, instead of putting the hash
3316 IDENTIFY command now also checks that client->nickname must be
3317 valid. If it is not if will request the data from the server who
3318 owns the client. Added new function
3319 silc_server_command_identify_check.
3321 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3322 to set the command to already allocated Command Payload.
3324 * Tested private message sending in router environment with two
3325 routers, two servers and two clients. Fixed minor bugs and now
3328 * Fixed segfault from client's NAMES command. Used to crash if
3331 * Forwarded packets must not be routed even if it is not destined
3332 to the receiver. Changed server code comply with this.
3334 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Added `require_reverse_mapping' boolean value to ServerParams
3337 structure. If TRUE (not default) the server will require that
3338 the connecting host has fully qualified domain name.
3340 If the reverse mapping is not required and hostname could not be
3341 found the IP address is used as hostname.
3343 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Implemented version string checking to both client and server.
3346 The check is incomplete currently due to the abnormal version
3347 strings used in development version of SILC.
3349 * Changed all command functions in server to use the new
3352 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * Changed char *data to unsigned char *data in ID Cache system to
3355 support binary data as ID Cache data. Changed code to support
3356 binary data in lib/silccore/idcache.c.
3358 * Renamed silc_server_packet_relay_command_reply to
3359 silc_server_command_reply as it is normal packet receiving
3360 function. Rewrote the function to accept command replys for
3361 servers and not only for clients.
3363 * Mark remote router always as registered server if we are connecting
3364 to it. Otherwise, commands sent by the router to us are ignored.
3366 * All ID List find routines now returns the ID Cache Entry pointer
3367 as well if requested.
3369 * WHOIS command works now in router environment, tested with two
3370 routers, two servers and two clients.
3372 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3373 in router environment (as it is almost equivalent to WHOIS) but
3374 hasn't been tested thoroughly. Added new functions:
3376 silc_server_command_identify_parse
3377 silc_server_command_identify_send_reply
3378 silc_server_command_identify_from_client
3379 silc_server_command_identify_from_server
3381 * Disabled route cache adding because adding two different ID's with
3382 same IP replaces the old cache entry thus giving wrong route.
3383 The entry->router->connection is always the fastest route anyway
3384 so route cache may not be needed. Of course, new routes maybe
3385 established after receiving the ID when the entry->router->connection
3386 might not be anymore the most optimal.
3388 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Add route cache for received ID for fast routing.
3392 * Added silc_server_packet_route to route received packet on router
3393 that is not destined to us.
3395 * Renamed silc_server_get_route to silc_server_route_get.
3397 * Added id_string and id_string_len fields into SilcServer to
3398 include encoded ServerID for fast comparing without excess
3399 encoding of the ID's.
3401 * Cleaned up WHOIS command on server side. Added following static
3404 silc_server_command_whois_parse
3405 silc_server_command_whois_check
3406 silc_server_command_whois_send_reply
3407 silc_server_command_whois_from_client
3408 silc_server_command_whois_from_server
3410 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3411 arguments in command replies. All command functions should be
3412 updated to use this macro.
3414 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3416 * Minor typo fixes on command reply handling on server.
3418 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3420 * Added silc_server_command_add_to_channel internal routine to add
3421 the client to the channel after router has created the channel and
3422 sent command reply to the server.
3424 * Added generic silc_server_send_command to send any command from
3427 * Use static buffer with ID rendering instead of duplicating data.
3429 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Fixed a channel user mode bug when joining to a channel server gave
3432 everybody channel founder rights, oops.
3434 * We mark ourselves as the router of the incoming server connection
3435 if we are router ourselves. This way we can check in some packet
3436 sending functions whether it is locally connected server. For
3437 incoming router connections we put NULL.
3439 * For router sending packets locally means now always sending the
3440 packet cell wide; to local clients and local servers. For normal
3441 server sending packet locally means sending it to only local
3444 * Fixed the JOIN command to really work in router environment. If the
3445 channel is created it is always created by the router. Router is
3446 also responsible of making the initial joining to the channel,
3447 sending JOIN notify to the sending server and distributing
3448 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3449 does not exist server doesn't do anything else but forward the
3450 command to the router which performs everything.
3452 * Added silc_server_send_channel_key function to send the Channel Key
3455 * Added silc_server_create_channel_key to create new channel key. The
3456 channel key is now re-generated everytime someone joins or leaves
3457 a channel, as protocol dictates. Note: channel->key_len is the
3460 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3462 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3463 packet_receive.[ch] to separate packet sending and receiving
3464 routines. The server.[ch] now includes everything else including
3465 actual packet processing (writing and reading data) and other
3468 Renamed silc_server_private_message_send_internal to
3469 silc_server_send_private_message. The routine is still though
3470 used only to relay private messages as server does not send
3471 private messages itself.
3473 Renamed silc_server_new_channel to silc_server_create_new_channel
3474 and added new function sicl_server_new_channel that handles the
3475 incoming New Channel packet. Added also new sending function
3476 silc_server_send_new_channel to send New Channel Payload.
3478 * Added new function silc_server_notify to process incoming notify
3479 packet to the server/router. Server may then relay the notify
3480 to clients if needed.
3482 * Added new function silc_server_new_channel_user to process incoming
3483 New Channel User packet. Router will redistribute the packet and
3484 send JOIN notify to its local clients and locally connected servers
3485 if needed. Normal server will send JOIN notify to its local client
3486 on same channel when received this packet. Added also corresponding
3487 sending function silc_server_send_new_channel_user to sent the
3490 * Added boolean route argument to send_notif_to_channel and
3491 packet_send_to_channel functions to attempt to route the packet
3492 if it is TRUE and send only locally if it is FALSE.
3494 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * silc_server_replace_id now broadcasts the received replace ID
3497 packet if it is not broadcast packet already. The router must
3498 broadcast to inform other routers about changed ID.
3500 * Added backpointer to server's router into SilcServer context in
3501 silcd/server_internal.h.
3503 * Fixed silc_server_packet_broadcast to send correct broadcast
3506 * The channel key is now distributed to the local client as soon
3507 as it is received from the router (in router environment) so that
3508 no other packet may be sent for the channel until client has
3511 * silc_server_remove_channel_user now broadcasts the received
3512 Remove Channel User packet if it is not broadcast packet already.
3513 The router must broadcast to inform other routers about removed
3516 * Added users field into SilcPacketContext that is a reference count
3517 of the context. One can increase the reference count by calling
3518 silc_packet_context_dup which is now changed to just increase the
3519 reference count instead of duplicating the data. The reference
3520 count is decresed by calling silc_packet_context_free that will
3521 free the data after the reference count hits zero.
3523 For now on the packet context and everything allocated into it
3524 (including the raw packet from network) must be freed by calling
3525 the new silc_packet_context_free function. Added also new function
3526 silc_packet_context_alloc that must be used now to allocate the
3527 context. This also means that if a routine is asynchronous from
3528 silc_[client/server]_packet_parse_type the packet context must
3529 be duplicated by calling silc_packet_context_dup. Otherwise it
3530 gets free'd after silc_[client/server]_packet_parse_type returns.
3531 Also, one must remember that if packet is duplicated then its
3532 reference count must be decresed by calling the free function as
3533 many times as it was duplicated.
3535 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3536 from both client and server.
3538 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * Made joining to a channel working in router environment.
3542 * Cleaned up JOIN command on server side and create function
3543 silc_server_command_join_channel internal routine to make the
3546 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3548 * Changed silc_command_pending list to SilcDList. Also, added
3549 `ident' field to SilcServerCommandPending structure to identify
3550 the reply and to call correct callback.
3552 Added silc_server_command_pending_check function to replace the
3553 corresnponding macro. The silc_command_pending list is not
3556 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3557 to set identifier to previously allocated Command Payload. It
3558 is used to set identifier for command when resending Command
3561 * Added silc_command_payload_encode_payload to encode Command
3562 Payload buffer from SilcCommandPayload structure.
3564 * Added silc_argument_payload_encode_payload to encode Argument
3565 payload buffer from SilcArgumentPayload structure.
3567 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Changed WHOIS command to support router connection on server side.
3570 The whois request is always sent to router unless the server is
3571 standalone server. After server has received the reply from the
3572 router will it send the reply to the client.
3574 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3575 broadcast received broadcast packet. The function is used only
3576 by router. The broadcast packet is always sent to the router's
3579 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3580 render given ID to printable string, for log files for example.
3582 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Made basic router to router connections working. At least they
3585 can now connect to each other but nothing really works the way
3586 they are supposed - yet.
3588 * Added new initiator token to RouterConnection configuration
3589 file in silcd/serverconfig.[ch]. It is used to tell whether we
3590 are the initiator to the remote router or whether we'll expect
3591 the other end to connect.
3593 * Moved registering of listener task to silc_server_init, hence
3594 the server starts listenning as soon as it is run, even if it
3595 does not have connections to other routers. Let's see how well
3598 * Changed default connection retry timeouts for more suitable in
3601 * Removed cipher and such arguments from silc_idlist_add_client
3602 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3603 Added new function silc_idlist_add_data to add the keys and stuff
3606 * Added SilcIDListData structure and added it to SilcClientEntry
3607 and SilcServerEntry as their first field in the structure. This
3608 way we can explicitly cast the ID entries to the SilcIDListData
3609 structure and get common data for the entries. In past, we had
3610 to first check what type of connection it is and then cast it to
3611 correct ID entry type. Now, we can directly cast the opaque
3612 pointer to the SilcIDListData (no matter what ID entry it actually
3613 is) and get the data needed.
3615 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3618 in some circumstances even if threre were timeout tasks, though not
3619 IO tasks, but tasks anyway. Now fixed.
3621 * Defined SilcServerConnection structure to hold connection specific
3622 stuff about directly connected servers and routers. The definition
3623 is currently in silcd/server_internal.h. I thought about having
3624 a bit more important role fro this struct but for now it is used
3625 only when connecting to other server (or router actually).
3627 * Added connecting retry support in server when connecting to
3628 router(s). The retry feature implement exponential backoff
3629 algorithm. Also, added SilcServerParams structure to hold default
3630 parameters for server. For now, it include these retry settings
3631 and are hard coded. After server is moded to be as Silc Server
3632 Library this structure will be more important.
3634 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3636 * Changed client librarys channel->clients table to SilcList and
3637 changed code accordingly.
3639 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * Changed client's channel table to SilcList and changed code
3642 accordingly. Also changed SilcChannelClientEntry to include back-
3643 pointer to the channel so that client entry can use that structure
3644 as list as well and we have fast cross-reference to the channel.
3645 This change dramatically decreased the complexity of channel
3646 handling with client entry and vice versa (removed one extra
3647 loop when searching for channel entry from many functions).
3649 * Changed server->sim from table to SilcDList and changed code
3652 * NAMES command can now be used from user interface. It will show
3653 the user list on the channel, neatly.
3655 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3656 Code now saves realname of the user if it becomes available.
3658 * Renamed configure.in to configure.in.pre and made ./prepare
3659 script to automatically add correct version string to
3660 configure.in which it creates from configure.in.pre.
3662 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * NAMES command reply now shows users mode with the nickname when
3667 * Moved silc_client_ch[u]mode[_char] functions from
3668 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3669 place sucks, they are utility functions and should be in some
3672 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3674 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3677 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Added TRQ (efficient deque and list library) into lib/trq. This is
3682 a very good list library that is currently used in the SILC. Defined
3683 SilcList API over the library because I didn't like the API very
3684 much. See lib/trq/silclist.h for the API and examples of how to
3685 use the API. Fixed various places in the code to use the new
3686 SilcList API. The SilcList is meant for lists that has a structure
3687 already defined as a list. It is not suitable to add just some
3688 context to the list (in TRQ, the context is the list actually).
3690 So, I defined SilcDList that can be used for the purpose where
3691 predefined list structure does not exit. This can be used as
3692 such list. Now some context just can be added to the SilcDList.
3693 Currently this list is not used in the SILC just yet, though there
3694 are a lot places where this can replace dynamically allocated
3695 tables and I will fix these places, later, to use SilcDList.
3696 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3697 and use TRQ internally).
3699 Also fixed some annoying warning messages that the original TRQ
3700 code generated. Also minor changes to TRQ's Makefile.in.
3702 * Added support for querying by Client ID to both WHOIS and
3703 IDENTIFY commands into server, as required by the protocol.
3705 * Removed method function pointers from SilcBuffer structure. They
3706 weren't used to anything and just increased the context size for
3707 no good reason. This change also made silc_buffer_alloc and
3708 silc_buffer_free functions inline functions.
3710 * Disabled command flooding detection support until it's fixed so
3711 that it accepts commands in but does not execute them more than once
3714 * Added silc_net_localhost(), to return local hostname, into
3715 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3716 that must be initialized before calling silc_client_init.
3718 * Added new function: silc_server_send_notify_on_channels to send
3719 notify messages to all channels client has joined. It is assured
3720 that the message is sent only once per client.
3722 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3723 lib/silcutil/silcutil.[ch] as silc_format function. The new
3724 function is generic and is used by server as well, not only by
3725 the logging routines.
3727 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3728 the provided version string was not acceptable. Added new function:
3729 silc_ske_check_version into lib/silcske/silcske.h. The function
3730 must be implemented by the application (client or server) and it
3731 does not reside in the SKE library. The function checks the version
3732 string remote end sent.
3734 * Added back pointers (to opaque context and to SilcSocketConnection)
3735 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3737 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3738 duplicate packet context structure.
3740 * Changed `notify' client operation to send same arguments as client
3741 receives from server except for ID's. ID's are mapped to correct
3742 ID entry and that is returned. Also, if channel entry is not sent
3743 by server but the notify is for channel the channel entry is sent
3744 to application (otherwise application doesn't know that it is for
3745 channel (library gets it from packet's Destination ID)).
3747 * Added silc_client_remove_from_channels into client library to
3748 remove a client from all channels it has joined to. Used when
3749 received SIGNOFF notify from server. Added also new function
3750 silc_client_replace_from_channels to replace old ID entry with
3751 new ID entry on all channels. Used when received NICK_CHANGE
3754 * Fixed ID Cache list handling in silc_idlist_get_client in
3755 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3756 to get (or query) client by ID.
3758 * Updated TODO list.
3760 * Added connection authentication status message defined by the
3761 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3762 support for these into the code in client and server side.
3764 * Added generic function silc_client_send_command to send any command
3765 with variable argument list. Application should use this function
3766 to send commands if the command functions provided by the library
3767 does not suite for the application's user interface needs.
3769 * Added new `failure' client operation. Application is notified about
3770 received failure packet if client is executing a protocol. In this
3771 case the protocol's execution has failed.
3773 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3774 is required by the protocol.
3776 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3777 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3780 * Added status flag to SilcSKE object to indicate realtime status
3781 of the SKE protocol.
3783 * Application receives now exactly same command reply arguments as
3784 the library receives from server. However, if ID is received the
3785 corresponding ID entry is returned to the application (eg. Client
3786 ID is mapped to correct SilcClientEntry entry and that is returned).
3787 Changed command_reply client operation due to this change.
3789 * Changed all ID's in commands and in command replys as ID Payloads.
3790 Change affected both client and server side codes.
3792 All ID's sent in SILC network (with execption of ID's in SILC
3793 Packet header) are sent in ID Payload to support variable length
3796 * Server now notifies nick changes and notifies all clients on
3797 the channels about the new nickname (about the new Client ID,
3800 * Implemented CMODE command to change channel modes. Supports all
3801 channel modes defined by the protocol specs except ban and invite
3802 lists. (Also, private channel key mode is supported but support for
3803 setting private channel key in client is missing, thus, this mode
3804 has no effect on client side (except that server requires that the
3805 client uses private channel key and normal channel traffic does not
3808 Also, invite mode works per se, but INVITE command does not work
3809 yet correctly, so you can set channel as invite only channel but
3810 inviting clients to the channel does not work (it is yet to be
3811 thought what's the best way to do it).
3813 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3814 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3815 Implemented CUMODE command to change user's mode on the channel.
3816 Supports all modes defined by the protocol specs.
3818 * Added NAMES command reply to return users modes on the channel.
3820 * Removed unnecessary and slow ciphers from lib/silccrypt.
3822 * Set SO_KEEPALIVE option to connection sockets by default.
3824 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3826 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3827 redefined the Notify Payload into protocol specs.
3829 * Added silc_id_payload_parse_id to get ID directly from raw
3832 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3835 accept searching by Client ID as well.
3837 * Added support for LEAVE and SIGNOFF notify types in client library.
3839 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3840 to parse ID Payload from raw data.
3842 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * Added flags parameter into silc_ske_assemble_security_properties
3845 function in lib/silcske/silcske.[ch].
3847 * Changed notify client operation to fit better for notify messages
3848 sent by server. The notify payload received from server is now
3849 passed to the application (after parsing it to SilcNotifyPayload).
3850 It is application's responsibility to retrieve the arguments
3851 from the payload and show the message the way it wants. The message
3852 sent by server is implementation specific.
3854 * Changed public keys to comply with the protocol specification.
3855 Old public keys are not supported anymore and are not compatible.
3857 * Removed nickname from Channel Payload as the latest draft removed
3858 it. The client must resolve the nickname from the NAMES command
3859 reply received when it joined the channel.
3861 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3863 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Fixed some errors in protocol specification drafts.
3867 * Created lib/silccore/silcnotify.c to implement Notify Payload
3868 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3869 generic payloads described by protocol specifications. The file
3870 includes implementations for ID Payload and Argument Payload.
3872 * Changed Command Payload implementation to use the new Argument
3873 Payload. Changed command_xxxx_payload to command_payload_xxxx
3874 to comply with SILC coding conventions.
3876 * Added suppport for Argument Payload handling in Notify Payload
3877 implementation as protocol requires it. Added the new support
3878 into server and client lib as well.
3880 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Added support for multiple nicknames on same channel. [n] is
3883 added locally to the nickname if there are more than one same
3884 nicknames on the channel.
3886 * Server now sends all nicknames that matched WHOIS request.
3887 Client also shows the list received from server.
3889 * Added TOPIC command to client side. User can now set and show
3890 current topic on channel.
3892 * Added MOTD command to client and server. Also, server sends the
3893 motd when client connects to the server.
3895 * Changed version strings to comply ISO 8601.
3897 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Fixed protocol error handling in client library. It should now
3900 cope even if the SKE fails for some reason.
3902 * Made new protocol specification drafts for submitting to IETF.
3904 * Implemented TOPIC command to server in silcd/command.c.
3906 * Added two new notify types into lib/silccore/silcnotify.h:
3907 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3908 notify nickname change and topic setting/change on a channel.
3910 * API change of command_reply operation in client library. The
3911 application gets now the status type received from server as well.
3913 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3915 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3917 * Cras fixed and optimized the packet handling even further and
3918 it should work now. Minor change to the prototype of function
3919 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3921 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3923 * Added new function into lib/silcutil/silcschedule.[ch]:
3924 silc_schedule_with_fd to select() a specified fd. The function
3925 returns after timeout expires or data arrives or goes. The
3926 function is used by packet routines to wait that all data is
3927 received from network.
3929 * Fixed data reading from network in lib/silccore/silcpacket.c.
3930 The code now assures that all data is read from the fd and then
3931 continues packet processing. This was a bug fix since the code
3932 used to drop some data in some circumstances.
3934 * Added new function into lib/silcclient/client.[ch]:
3935 silc_client_start_key_exchange to start key exchange after
3936 connection has been established to server. The code internally
3937 now uses this funtion but its main purpose was to provide it
3938 for applications that perform their own connecting. After
3939 application has created a connection it merely calls this
3940 function to start the key exchange between client and server.
3941 The library takes care of everything else after that.
3943 Updated also lib/silcclient/README to explain the usage of
3946 * Do not send to application information that connection has
3947 been established. Application gets notified it by connect
3950 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Applied cras's patch to add silc_schedule_one function. The
3953 function runs scheduler once and returns.
3955 * Fixed the scheduler after cras messed it up. The timeout
3956 handling works now as it's supposed to work.
3958 * Added into lib/silccore/ silcnotify.h to include notify
3959 message types support. Changed silc_server_send_notify*
3960 functions, in server.[ch], to support those new notify types.
3961 Added the support for the notify types into client library,
3962 as well. Added new notify client operation into ops.h in
3965 * Changed silc_server_packet_send_to_channel to send normal
3966 packets instead of just channel message packets. The function
3967 is now used to send the notify packets to channels. It is not
3968 used to send channel message packets anymore, as server never
3971 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3972 va_arg()s as it seems to require it nowadays. I guess, if SILC
3973 is compiled with older va_arg() the new code should work anyway.
3975 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3977 * Splitted core library. Core library (lib/silccore) includes
3978 now only SILC protocol specific core (and common) components.
3979 Created new utility library (lib/silcutil) that includes more
3980 generic purpose stuff. The stuff for util library was taken
3981 from the old core library. This was minor and easy split.
3983 * Created SILC Client Library (lib/silcclient) that includes
3984 implementation of the SILC client without user interface. This
3985 was major move from silc/ directory. The code has been changed
3986 so that it is transparent towards the user interface. The
3987 silc/ directory includes now the same user interface as before
3988 and it uses the new client library. Read lib/silcclient/README.
3989 Basicly, the client library performs everything else related
3990 to SILC except user interface handling. Also, configuration
3991 files are considered to be part of user interface and library
3992 does not handle them.
3994 This change also changed a lot of structures, function naming etc.
3995 Most important change was that SilcClientWindow object was
3996 renamed to SilcClientConnection in the client library. Created
3997 also new file lib/silcclient/ops.h. Also added new files
3998 silc/local_command.[ch] and silc/client_ops.[ch].
4000 All these changes were made to make it easier for user interface
4001 designers to create what ever user interface for the SILC client
4004 It is also expected that the server will be moved to lib
4005 directory as well and SILC Server Library will be created;
4006 sometimes in the future.
4008 * Removed Local commands from lib/silccore/silccommand.h as
4009 they are application specific and new client library does not
4010 handle any of those anymore.
4012 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4013 old client implementation in silc/.
4015 * Added support for callback functions in SILC_LOG_* macros.
4016 Application can now set its own callbacks that will be called
4017 instead of using the default functions that will always print
4018 the debug messages to stderr (or stdout). Also, debugging can
4019 now be disabled by setting silc_debug to FALSE and re-enabled by
4020 setting it to TRUE. Note, that logging will still work even
4021 if debugging is disabled.
4023 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4024 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4025 silc_log_reset_debug_callbacks.
4027 * To enable debugging in silc client one must give now -d
4028 option on command line.
4030 * Changed silc_schedule_init to automatically allocate task queues
4031 if they are not allocated before calling it.
4033 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Added GMP 3.1 into math library.
4037 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4039 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4040 a channel in SILC network. The packet is used by servers and
4041 routers to notify other routers that user has left a channel.
4042 This little feature was missing until now. Added the feature
4043 to protocol specification as well.
4045 Added functions: silc_server_send_remove_channel_user and
4046 silc_server_remove_channel_user into server.[ch].
4048 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4049 lib/silccore/silcpacket.h. However, they are not implemented
4052 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Fixed joining to a channel and sending channel messages
4055 between server and router. The channel message sending should
4056 now work inside a cell.
4058 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Fixed the private message sending between server and router.
4061 The private message sending should now work inside a cell.
4063 * Added silc_server_replace_id into server.[ch] to replace
4064 existing ID in the SILC network.
4066 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4067 and silc_idlist_replace_server_id into idlist.[ch] in server.
4069 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Fixed the server to server connections. Server can again now
4072 connect to router. Router to router connections probably does
4075 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Added dynamic protocol registering support. Now protocols can
4078 registered and unregistered on the fly. Patch by cras.
4080 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Added lib/contrib directory to hold routines that some platforms
4083 don't have but are needed by SILC.
4085 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4086 into lin/contrib to provide getopt() and getopt_long() for
4087 those who don't have it.
4089 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Added AWAY command to client. When away message is set and
4092 client receives a private message packet the client automatically
4093 replies to the sender with the away message.
4095 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4096 bug seemed to be the cause of recent problems when compiling
4099 * Added version detection support to SKE protocol specification
4100 and added the new changes to the SKE implementation as well.
4101 There were other minor changes in the SKE protocol as well.
4103 Many changes in lib/silcske/silcske.[ch] and in
4104 lib/silcske/payload.[ch].
4106 * Added ^U functionality, clear input line. Patch from cras.
4108 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4110 * Mainly small bugfixes on core library. Fixed some debugging
4111 logging and buffer overflow in silclog.c.
4113 * Updated config.sub and config.guess on the distribution tree.
4115 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4117 * Added command lagging support in server. Client may execute
4118 commands now only once in two seconds.
4120 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4122 * Optimized packet reception. MAC computation and checking is now
4123 also more optimized. A lot previously duplicated code is now
4124 used as generic by both client and server.
4126 * Fixed key pair generation in clientutil.c
4128 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Added into lib/silccore/silcbufutil.[ch] new function;
4131 silc_buffer_realloc.
4133 * Moved generic packet sending/encryption functions to
4134 lib/silccore/silcpacket.[ch] from client and server. Some
4135 rewriting of the functions.
4137 * Moved all generic packet reception/decryption functions to
4138 lib/silccore/silcpacket.[ch] from client and server. The
4139 packet processing is now much cleaner in both client and server.
4140 These were major changes in both client and server.
4142 * Created many common functions in server to do packet sending.
4143 Previously code were duplicated a lot, this has been removed
4146 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Rewrote major parts of the ID cache system. Don't know
4149 whether it is better now or not but at least the API is more
4152 * Major rewrite on ID cache stuff on client because of the ID
4153 cache API changes. Added idlist.c to client.
4155 * Also major rewrite on ID cache stuff on server as well.
4156 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4157 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4158 in hand, instead they are all put into the ID cache system now.
4159 All server_idlist_* routines uses ID cache now instead of
4160 traversing its own lists (those lists does not exist anymore).
4161 SilcIDList though still exists. Also, SilcXXXEntry's are
4164 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Finally made the SKE implementation compliant to the protocol
4167 specification. All mp integers are now binary encoded as
4168 opposed being HEX encoded.
4170 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4173 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4174 functions: silc_[encode/decode]_pem. Also added function
4175 silc_encode_pem_file to PEM encode with newlines ('\n') for
4178 * SILC public keys are now encoded either PEM or binary. Same
4179 option is for private keys as well. By default private keys
4180 are binary encoded and public keys PEM encoded. Silly HEX
4181 encoding were removed.
4183 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4184 function to create fingerprints.
4186 * Fixed a bug in SHA1; does not change the original data anymore.
4188 * Partly implemented INFO command on client and server side.
4189 Fixed CLEAR command. Changes to SERVER command; show current
4190 server(s) when giving command without arguments. Added
4191 VERSION command to client.
4193 * Added check to server that unregistered connections cannot
4194 execute commands (unless it is specificly allowed).
4196 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4198 * Fixed screen refresh.
4200 * Fixed channel joining bug from client. On some circumstances
4201 client tried to join to a channel it had already joined.
4203 * Added public key verification process into client's protocol.c.
4204 The client now verifies the public key from user and saves
4205 it into ~./silc/serverkeys/ directory.
4207 Added into: clientutil.[ch]: silc_client_verify_server_key.
4209 * Changed SKE protocol's silc_ske_initiator_finish function
4210 to accept callback function that verifies the received public
4211 key. Removed old silc_ske_verify_public_key function.
4213 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4216 silc_pkcs_private_key[_data]_set.
4218 * Made the password and public authentication more cleaner in
4219 server's protocol.c.
4221 * Removed historic and obsolete protocol `channel_auth' from
4222 both client and server.
4224 * Removed wrong way of sending command status messages from
4225 server to client in server's command.c. The old way violated
4226 protocol specification.
4228 Changes to silccore/silccommand.[ch]: removed
4229 silc_command_encode_status_payload -> not needed anymore,
4230 changed silc_command_encode_payload_va to accept extra
4231 argument on variable argument list. The argument type must
4232 now be provided to the function. Also, added new function:
4233 silc_command_encode_reply_payload_va which is same as
4234 normal command_encode_payload_va except command status type
4235 is provided as extra argument.
4237 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Added ~./silc directory handling. The directory includes the
4240 public and private keys for the client.
4242 Added silc_client_check_silc_dir, silc_client_create_identifier
4243 and silc_client_load_keys.
4245 * Implemented SILC protocol compliant public key. Added public
4246 and private key saving to and loading from files.
4248 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4249 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4250 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4251 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4252 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4254 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4255 silc_pkcs_load_[public/private]_key.
4257 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Added silc_server_get_route (route.[ch]) to get connection
4260 data for the fastest route for given ID.
4262 * Implemented INVITE command on client and server. The command
4263 were re-defined in the SILC Protocol Specification and the
4264 implementation now complies with the specification.
4266 * Implemented PING command on client and server.
4268 * Implemented NAMES command on client and server. The server side
4269 supports currently only normal server not router server yet.
4270 Some changes to NAMES definition in SILC protocol specification.
4272 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4274 * Implemented LEAVE command on client and server.
4276 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4277 again. This change was made to the protocol as well. Server
4278 should not violate the protocol specification anymore.
4280 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4283 was tested. SOCKS4 was not but should work anyway.
