1 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed the silc_server_remove_clients_by_server's channel
4 key re-generation. The hash table handling was incorrect
5 and would not work with many channels. Affected file is
8 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
10 * Changed the dynamic tables to static size tables in the
11 lib/silccrypt/silchmac.c.
13 * Removed GCC dependencies from the code. A patch by cras.
15 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
17 * Do not show the error "Error receiving packet bla bla"
18 in server if it really was not an error (-2 means that reading
19 is pending). Affected file silcd/server.c.
21 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
23 * Fixed a possible crash in silc_server_remove_clients_by_server
24 in silcd/server.c. Fixed there also some memory leaks.
26 * Fixed the silc_idlist_replace_client_id. It could replace
27 wrong key in the hash table. Affected file silcd/idlist.c.
29 * Do not check whether there are global users on the channel
30 if the channel->global_users is FALSE. Affected functions
31 silc_server_remove_from_one_channel and
32 silc_server_remove_from_channels in silcd/server.c. Also,
33 do not check if the removed client is local as we can be
34 sure that global client was not removed from the channel
35 and checking for global users is not needed.
37 * The silc_server_remove_clients_by_server now re-generates
38 the channel keys correctly for those channels that had
39 clients removed from them. Affected file silcd/server.c.
41 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
43 * Found the reason of random crashes in the server. We weren't
44 ignoring the SIGPIPE signal (which can be sent in write())
45 and it crashed the server. Affected file silcd/silcd.c.
47 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
49 * Assure that sock->user_data is not NULL in the function
50 silc_server_packet_send in silcd/packet_send.c.
52 * Disconnect the remote connection if it could not be added
53 to any ID lists in the server. The affected file is
56 * Check in silc_server_packet_send[_real/dest] that the
57 socket is not disconnecting and ignore the data if it is.
58 Affected file silcd/packet_send.c.
60 * Define inline to __inline on native WIN32 compilation.
61 Affected file includes/silcwin32.h.
63 * Added some explicit type casts for inline code since MSVC
64 require them. Affected files lib/silcutil/silcbuffer.h,
65 lib/trq/silcdlist.h and lib/trq/silclist.h.
67 * Print warning in log files from now on if the packet
68 decryption fails. Affected file silcd/server.c.
70 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
72 * Changed the `say' client operation's interface to accept
73 new `type' argument to indicate the type of the message sent
74 by the library. The application may filter the library's
75 messages according the type. The affected file is the
76 lib/silcclient/silcapi.h.
78 * Added two new functions to lib/silcclient/silcapi.h:
79 silc_client_del_client and silc_client_del_client_by_id.
80 Affected file lib/silcclient/idlist.c.
82 * Moved the clientincludes.h from includes/ to silc/ and
83 serverincludes.h from includes/ to silcd/.
85 * The modes for the CMODE and CUMODE are now passed as
86 uint32 for application with COMMAND_REPLY. The affected
87 file is lib/silcclient/command_reply.c.
89 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
91 * /WHOIS without arguments shows client's own information.
92 Affected file lib/silcclient/command.c.
94 * Changed PING to not accept any arguments. The specs
95 says that client can ping only the connected server so
96 requiring an argument is not needed. Affected file is
97 lib/silcclient/command.c.
99 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
101 * Fixed a fatal bug in private message sending and reception
102 encryption and decryption when using private message keys.
103 The implementation was incorrect and did not follow the
104 specification. It causd that some of the message were
105 lost since it did not use the sending and receiving keys
106 as the protocol suggests. This has been fixed and will cause
107 incompatibilities with older clients when sending private
108 message encrypted with private message keys. Affected files
109 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
110 and various other in Irssi SILC Client.
112 Added `responder' boolean argument to the functions
113 silc_client_add_private_message_key[_ske] to indicate when
114 the key is added as responder or initiator of the key
117 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
119 * Removed the silc_ske_check_version function and created
120 a SilcSKECheckVersion callback. Added also a function
121 silc_ske_set_callbacks that is now used to set all SKE
122 callbacks. The callback functions are not given to
123 the SKE functions anymore, but this function is used to
126 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
128 * Added `silc_version' argument to the silc_client_alloc
129 to define the version of the application for the library.
130 The library will use the version string to compare it
131 against the remote host's (usually a server) version
132 string. Affected file lib/silcclient/silcapi.h
134 * Added the KE protocol context to Key Agreement context
135 in client library so that we can abort the SKE if it
136 is in process when we get timeout. Affected file is
137 lib/silcclient/client_keyagr.c.
139 * Do not resolve the client ID forever if it returns in the
140 first time that such client does not exist. This was done
141 for example with private message. Affected file is
142 lib/silcclient/client_prvmsg.c.
144 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
146 * Do not add regex.h for WIN32. The affected file
147 includes/silcincludes.h.
149 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
150 not work yet 100%. It generates the DLL's automatically
151 when compiling with --with-win32 under cygwin.
153 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
155 * lib/contrib/regex.c is not compiled on WIN32.
157 * Added silc_net_get_socket_opt function to the
158 lib/silcutil/silcnet.h.
160 * Added includes/silcwin32.h for WIN32 specific includes
163 * Do not use ptime structure or any of the posix process
164 functions on WIN32 in lib/silccrypt/silrng.c.
166 * Added silc_gettimeofday to provide generic function
167 for struct timeval on all platforms. Added the function
168 to lib/silcutil/silcutil.h.
170 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
172 * Moved the lib/silccore/silcsockconn.[ch] to the utility
173 library as they clearly belong there. As a plus side we
174 can make the actual socket connection routines platform
177 Added also new generic function silc_socket_read and
178 silc_socket_write (that used to be silc_packet_[read/write].
179 The implementation of these are platform specific.
181 * Added WIN32 specific routines of silc_socket_[read/write]
182 to lib/silcutil/win32/silcwin32sockconn.c.
184 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
186 * Added preliminary support for native WIN32 compilation under
187 cygwin (using the -mno-cygwin option for GCC) to the
188 ./configure.in.pre. The --with-win32 now prepares the
189 compilation for native WIN32.
191 * Rewrote the SILC Scheduler interface in the file
192 lib/silcutil/silcschedule.h. The scheduler is now context
193 based and does not have anymore any global static scheduler.
194 Moved the Unix scheduler to the lib/silcutil/unix/ directory
195 and created lib/silcutil/win32 directory for WIN32 based
198 * Added Unix specific network routines to the
199 lib/silcutil/unix/silcunixnet.c and the old
200 lib/silcutil/silcnet.c includes now only generic routines.
202 Added WIN32 specific network routines to the
203 lib/silcutil/win32/silcwin32net.c.
205 * Added Unix specific utility functions from the
206 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
208 * Added WIN32 SILC Scheduler to the file
209 lib/silcutil/win32/silcwin32schedule.c. The code is of course
212 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
214 * Do not handle JOIN notify in the server if the target client
215 is not registered (idata->registered == FALSE). The affected
216 file is silcd/packet_receive.c.
218 * Update the nickrec->founder in event_cumode in the Irssi SILC
219 client. Affected file irssi/src/silc/core/silc-channels.c.
221 * Fixed the CUMODE_CHANGE notify handling in the server when
222 server and router are announcing their clients on channels.
223 Now the mode changes are saved and notified correctly. The
224 affected file is /silcd/packet_receive.c.
226 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
227 They really did not replace the cache entry in the ID Cache.
228 Now they do that. Affected file silcd/idlist.c.
230 * Fixed the KICK notify handling in the Irssi SILC client to
231 update the channel records so that the kicked client does not
232 appear to be on the channel. The affected file is
233 irssi/src/silc/core/silc-channels.c.
235 * Always update the conn->current_channel when executing command
236 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
238 * Fixed the KILL notify handling in Irssi SILC client to remove
239 the killed client on all channels.
241 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
243 * Fixed the silc_parse_command_line to remove extra spaces
244 from the start and end of the arguments. Affected file is
245 lib/silcutil/silcutil.c.
247 * Cancel and free any active protocol in the function
248 silc_server_close_connection. Affected file silcd/server.c.
250 * Cancel and free any active protocol in the function
251 silc_client_close_connction. Affected file is
252 lib/silcclient/client.c.
254 * Do not execute the KILL command for clients that are in
255 history (ie. they are not in the network). Affected file is
258 * Fixed KILL notify handling, client does not crash anymore.
259 Affected file irssi/src/silc/core/silc-channels.c.
261 * Reduced the default packet buffer size from 2048 to 1024 in
262 lib/silccore/silcpacket.c.
264 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
265 counter to the SKE context that is incresed when the SKE library
266 performs async operation outside the library. If the outside
267 process frees the SKE context and FREED status will be set
268 and the library will detect after the sync operation that the
269 libary is freed. The affected files are
270 lib/silcske/silcske[_status].[ch].
272 * Resolve the client entry information in the function
273 silc_client_channel_message to assure that NULL pointer is not
274 passed as client entry to the application. */
276 * Fixed the task timeout calculation to assure that there is
277 never negative timeouts. The affected file is
278 lib/silcutil/silcschedule.c.
280 * Fixed the channel user mode notification sending in server.
281 It was sent point-to-point to the router (or to server by router)
282 but it needs to be destined to a channel. The routines now
283 supports sending the channel user mode notifys to the channels
284 when announcing clients and channels. Affected files are
285 silcd/server.c and silcd/packet_receive.c.
287 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
288 It did not actually replace the old channel entry in the cache.
289 Affected file lib/silcclient/client_notify.c.
291 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
293 * Fixed a possible crash in silc_packet_send_prepare. It now
294 assures always that there is enough space in the buffer and
295 at the tail area of the buffer (for MAC).
297 Fixed the inbound buffer reallocation in silc_packet_read.
298 It was old code and did not handle the reallocation correctly.
301 The affected file is lib/silccore/silcpacket.c.
303 * Fixed buffer overflow in silc_parse_nickname in the file
304 lib/silcutil/silcutil.c.
306 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
308 * make install generates new server keys only if there is not
311 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
313 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
314 Added check that if the NOREPLY is set then we will not send
315 the away message. This avoids infinite loop of away messages
316 if both clients are away. The affected file is
317 lib/silcclient/client_prvmsg.c.
319 * Fixed client crash if /NICK was given without arguments.
320 Affected file lib/silcclient/command.c.
322 * Server does not send the invite list in INVITE command back
323 to the client if the list was not altered. Added this notion
324 to the protocol spec as well. Affected file silcd/command.c.
326 Fixed possible crash in INVITE command by checking the
327 value of silc_server_get_client_route command.
329 * Fixed the INVITE notify type handling. The arguments are now
330 taken in correct order and client does not crash. The affected
331 file is irssi/src/silc/core/silc-channels.c.
333 Removed the "Inviting xxx to channel" message from the
334 client library away and let the application handle it.
335 Affected file lib/silcclient/command.c. Added that message
336 to Irssi SILC client's message formats.
338 * Fixed CMODE command crash in client. It now checks the
339 amount of arguments correctly and does not crash. The affected
340 file is lib/silcclient/command.c.
342 * Do not create new channel automatically in silc_channels_join
343 but check whether the channel by that name already exists.
344 Affected file irssi/silc/core/silc-channels.c.
346 * Do not send the SERVER_SIGNOFF to router if the disconnected
347 entity was the router. Affected file silcd/server.c.
349 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
350 SILC client as it was missing from there.
352 Added the handling of the KICK notify to the Irssi SILC client
353 as it was missing. Added "you have been kicked" message to
354 Irssi SILC client's message modules formats.
356 Added the handing of the KILL notify to the Irssi SILC client
357 as it was missing. Added the kill message module formats
360 The affected file is irssi/src/silc/core/silc-channels.c.
362 * The router did not save the channel mode the server announced.
363 Affected file silcd/packet_receive.c.
365 * Fixed a possible crash in INFO command in server. If the
366 server did not provide the server info it crashed. Affected
367 file silcd/command.c.
369 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Fixed the GETKEY command in the server to check also the
372 global list. Otherwise the GETKEY would not work correctly
373 in normal SILC server. Affected file silcd/command.c.
375 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
377 * Fixed GETKEY crash, it crashed if the command did not succseed.
379 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
381 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
382 is now real and not just an macro interface to GMP.
384 Removed the entire GMP from the source tree and imported new
385 NSS MPI library instead. Reason for removing GMP is that it is
386 extremely large and compiles extremely slow. The NSS MPI
387 is only a few files and compiles in less than 10 seconds.
388 The speed is also about the same as GMP. The MPI is imported
391 If the system has GMP installed we will still use the GMP.
392 If it is not then the NSS MPI will be compiled.
394 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
396 * Merged a long nickname (127 characters long) crash bugfix from
397 Irssi CVS tree. Affected file irssi/src/core/misc.c.
399 * Merged a freed memory reference bugfix from Irssi CVS tree.
400 Affected file irssi/src/core/commands.c.
402 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
404 * Added the server's public key sving and verification to the
405 server when performing the SKE. This was missing and the
406 remote server's (or router's) public key was accepted without
407 checking whether we have it previously or trust it at all.
408 Affected file silcd/protocol.c.
410 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
412 * Check in the silc_server_timeout_remote if protocol is active
413 and make sure that the protocol's final callback is called so
414 that all memory if freed. Affected file silcd/server.c.
416 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
418 * silc_server_whois_send_reply crashed the server if the nickname
419 was 127 characters long. Affected file silcd/command.c.
421 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
423 * Added sanity check to the silc_server_new_client. If the hostname
424 is provided inside username then check that the provided hostname
425 really is the same as the resolved one. If the hostname was not
426 resolved then check it from the public key. Affected file is
427 silcd/packet_receive.c.
429 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
430 if the server disconnected us and the connection is not valid
431 anymore. Affected file irssi/src/silc/core/silc-channels.c.
433 * Moved the silc_client_[chmode|chumode|chumode_char] away from
434 the library to the lib/silcutil/silcutil.[ch].
436 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
438 * Close log file after open. Affected file
439 lib/silcutil/silclog.c.
441 * Check whether sock == NULL in silc_client_send_packet and return
442 if it is. Affected file lib/silcclient/silcclient.c.
444 * Check rec->entry == NULL in the Irssi SILC Client before
445 sending the channel message. Affecte file is
446 irssi/src/silc/core/silc-servers.c.
448 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Merged a splitted window bugfix from Irssi CVS tree. The
451 affected file is irssi/src/fe-text/textbuffer-view.c.
453 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
454 It did not print nickname.
456 * Improved the distributions system a bit.
458 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
460 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
461 irssi/src/fe-text/gui-window.c.
463 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
464 to in-active server. The affected file is
465 irssi/src/silc/core/client_ops.c.
467 * Resolve the client in USERS command reply if the entry does
468 not have username resolved. The affected file is
469 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
470 command to WHOIS command to really resolve stuff. The USERS
471 is not used any more in any critical section so WHOIS can
472 be used even though it might be slower than IDENTIFY.
474 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
477 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
479 * Changed the protocol API a bit more consistent in the
480 lib/silccore/silcprotocol.[ch].
482 * Changed the following headers to ROBODoc format:
484 lib/silccore/silcpayload.h
485 lib/silccore/silcprotocol.h
486 lib/silccore/silcsockconn.h
488 All core library headers are now formatted.
490 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
492 * Fixed a bug in Irssi SILC client; do not show that you are
493 server/router operator if you really are not. Affected file is
494 irssi/src/silc/core/client_ops.c.
496 * Renamed silc_command_free_payload to silc_command_payload_free.
497 Affected file lib/silccore/silccommand.h
499 * Added silcmath.h to include the prototoypes of various routines
500 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
503 * Changed the following headers to ROBODoc format:
505 lib/silccore/silcchannel.h
506 lib/silccore/silccommand.h
507 lib/silccore/silcid.h
508 lib/silccore/silcidcache.h
509 lib/silccore/silcmode.h
510 lib/silccore/silcnotify.h
511 lib/silccore/silcpacket.h
512 lib/silcmath/silcmath.h
514 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
516 * Added checking to the server code not to start the server if
517 ciphers and stuff are not configured properly. Affected files
518 silcd/serverconfig.[h] and silcd/server.c.
520 * Changed the layout of the header files of the public interfaces
521 in the SILC libraries. The new layout supports ROBODoc
522 documentation tool (and some others) so that it is easy to create
523 a library reference manual. All the other headers and source
524 code must still follow the CodingStyle document. Also source
525 code must not include these ROBODoc stuffs, only the headers.
526 Furthermore, all public interface headers must now be named
527 by using `silc' prefix, example: silcapi.h, silccipher.h.
528 Some files were renamed due to this. All the other headers
529 must not be used as public interfaces. I will update the
530 CodingStyle document later. Changed following headers, so far:
532 lib/silcclient/silcapi.h
533 lib/silccore/silcauth.h
534 lib/silccore/silcprivate.h
535 lib/silccrypt/silcdh.h
537 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
541 * Removed silc_client_packet_send_flush from the client library
542 as it is not needed. Affected file lib/silcclient/client.[ch].
544 * Added printing of message of unresolved authentication method
545 to the Irssi SILC client. Added it to the module formats.
546 Removed the same message from the client library.
548 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
550 * Added new distribution feature, DISTLABEL. Every distribution
551 can define own preprocessor label that can be used in the
552 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
553 file distributions, acconfig.h.pre and prepare.
555 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
557 * Added Makefile.defines_int to include the actual definitions
558 for Makefile.defines.in. Tested the new distribution system,
559 created distributions and tested installation.
561 * Added AWAY message printing to the Irssi SILC client. Added
562 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
564 * Added SCONNECT command to call the SILC's CONNECT command.
565 Cannot use CONNECT directly since Irssi uses that internally.
566 Affected file irssi/src/silc/core/silc-servers.c.
568 Added ACTION local command. It is same as ME command but takes
569 the channel as mandatory argument.
571 Rewrote some of the Irssi's help files to suite for SILC
574 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
576 * Added Makefile.defines[.in] that should for now on be included
577 in all Makefile.am file in the source tree. That file includes
578 all common compilation definitions for SILC source tree.
580 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
582 * Minor changes to the ./prepare script to change the package
583 name according the distribution name to the configure.in.
585 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
587 * Created new distribution system. Added file `distributions'
588 that defines all the distributions that can be created out of
589 the SILC source tree. The ./prepare script now reads that
590 file to determine how to prepare the distributions. The
591 first argument to the ./prepare is the name of the distribution
592 and second is the version of the distribution. If given
593 without arguments it creates the default (toolkit) distribution
594 with the default version (defined in ./prepare).
596 All Makefile.am files that are subject to the distributions
597 are now named as Makefile.am.pre. These are ./Makefile.am
598 and lib/Makefile.am. Others may be changed later.
600 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
602 * Added invite list, ban list, some key management and connection
603 error message printing to module formats in the Irssi SILC client.
605 * Added new silc_client_set_away_message to set the away message
606 that is back to the person who sent private message. The
607 affected file lib/silcclient/silcapi.h and the
608 lib/silcclient/client_prvmsg.c.
610 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
612 * Fixed the private message sending in the Irssi SILC client,
613 added local command KEY to the Irssi SILC client.
615 Added key management and key agreement message formats to the
616 irssi/src/fe-common/silc/module-formats.[ch].
618 Added USERS (alias WHO) printing, server/router operator
619 indication and LIST command printing to the module formats.
621 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Fixed channel joining notify handling, cumode notify handling
624 from Irssi SILC client.
626 * Added SILC specific module-formats to the Irssi SILC client so
627 that SILC specific message hilighting, colors etc is possible.
628 Affected file irssi/src/fe-common/silc/module-formats.[ch].
630 Added channel mode, channel user mode, actions, notices,
631 whois and whowas printing to the the module-formats.c.
633 * Fixed a bug in channel deletion in the server. The channel
634 is not left to the cache even if the channel founder auth mode
635 is set when there are no users anymore on the channel. Affected
638 * The silc_net_localhost now resolves the entire hostname including
639 the domain name. Affected file lib/silcutil/silcnet.c.
641 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
643 * Changed the ask_passphrase client operation to be ascynchronous.
644 It has now a completion callback and a context that the
645 application must call after it has got the passphrase from
646 the user. Affected files lib/silcclient/silcapi.h,
647 lib/silcclient/protocol.c, lib/silcclient/command.c and
650 Added SilcAskPassphrase callback that the application calls
651 to deliver the passphrase to the library.
653 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
654 The public key verification and especially a certificate
655 verification is asynchronous procedure.
657 Added new SILC_SKE_STATUS_PENDING status to indicate the
658 request is pending and a callback will be called to finalize
661 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
662 indicate that remote end did not send its public key (or
663 certificate), even though we require it. Added check for this
664 condition in the SKE. This was a security bug, now fixed.
666 Defined new SilcSKEVerifyCbCompletion callback that is called
667 when the verification process is completed.
669 The affected files lib/silcske/silcske_status.h and
670 lib/silcske/silcske.[ch].
672 * Changed the verify_public_key client operation to be async
673 as well. Defined SilcVerifyPublicKey callback that is used to
674 indicate the success of the public key verification process.
676 Changed the server and client to use the new async client
679 * Changed the Irssi SILC client's internal scheduler to be called
680 twice as many times as it used to be. As a result the client
681 should be a bit faster now. Affected file is
682 irssi/src/silc/core/silc-core.c.
684 * Added support to Irssi SILC client of asynchronous public key
685 verification and passphrase inquiry. Affected file is
686 irssi/src/silc/core/silc-core.c.
688 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
690 * Do not say "You have left channel %s" in client library.
691 Moved it to the application. Affected files are
692 lib/silcclient/command.c and silc/client_ops.c.
694 * Fixed silc_client_get_clients. Command context was not
695 duplicated and was freed memory in the callback. Affected
696 file lib/silcclient/idlist.c.
698 * Do not say "you are now talking..." on JOIN command in the
699 client library. The appliation must handle it.
701 * Do not say ".. changed topic to" in command reply in the
702 client libary. The application must handle it.
704 * Fixed TOPIC command sending in the client library.
706 * Fixed a memory leak in silc_client_command_free in the file
707 lib/silcclient/command.c.
709 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
711 * Imported a modified version of Irssi client to the source tree.
712 The Irssi will be used to create a new client called
713 Irssi SILC. Imported to irssi/.
715 Added silc_core_init_finish function to the Irssi. Affected
716 file irssi/configure.in.
718 A lot changes in the Makefile.ams around the irssi tree.
720 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Do not rehash if the new size is same as the old size of the
723 hash table, in the silc_hash_table_rehash*. The affected file
724 lib/silcutil/silchashtable.c.
726 * Replaced hash_table_del_by_context calls from the server
727 (when channel->user_list and client->channels) to the
728 hash_table_del as it is sufficient and faster.
730 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
732 * Added silc_hash_table_list, silc_hash_table_get and the
733 SilcHashTableList structure to provide an alternative way to
734 traverse the hash table. The affected files are
735 lib/silcutil/silchashtable.[ch].
737 * Changed the server's idlist routines to use the hash table
738 routines to optimize the code.
740 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
742 * Replaced the client entry's `channel' list and channel entry's
743 `user_list' list to hash tables for optimized lookup. Changed
744 the code to use the hash table interface around the code.
745 Affected file lib/silcd/idlist.[ch].
747 * Added `auto_rehash' boolean argument to the function
748 silc_hash_table_alloc to indicate whether the hash table should
749 auto-rehash when it thinks is appropriate time. It will
750 increase the hash table size if the there is twice as much
751 entries in the table than the size of the table, and will
752 decrease the size if there are twice as less entries than
753 the size of the table.
755 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
757 * Fixed silc_xxx_get_supported to not crash at some circumstances.
759 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * silc_idcache_purge_by_context deletes the entry now by context
762 as it is supposed to do. Affected file lib/silccore/idcache.c.
764 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
765 client is not anymore valid (WHOWAS givens the info) and not
766 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
768 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Removed the `data' and `data_len' arguments from the ID Cache
771 interfaces and added `name' argument. ID Cache does not handle
772 anymore the binary data only a names associated with given ID.
774 * When hashing a Client ID with silc_hash_id the entire ID is
775 not hashed anymore, instead only the hash of the Client ID is
776 hashed. This way we can access the Client ID from the cache
777 with Client ID but with the hash of the ID (which is a hash of
778 the nickname) as well without any difference in performance.
780 Added also silc_idcache_find_by_id_one_ext to do one on one
781 searching when we have the actual ID. Added also function
782 silc_hash_client_id_compare. The affected files are
783 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
785 * When hashing the name associated with a ID it is always done
786 in lowercase. This way we can access the cache without worrying
787 about case-sensitivity, even though, for example nicknames are
790 * Fixed a bug in server with channel message sending. It put
791 wrong ID type as destination ID. The affected file
794 * silc_idcache_del_by_context now deletes from all hash tables
795 by context. Affected file lib/silccore/idcache.c.
797 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
799 * Changed the client library to use the new ID Cache interface.
800 Changes around the source tree.
802 * Added silc_hash_table_rehash_ext to rehash with specific
803 hash function. Affected file lib/silcutil/silchashtable.[ch].
805 * Added silc_hash_string_compare to compare two strings in the
806 hash table. Affected file lib/silcutil/silcutil.[ch].
808 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
810 * Added new function silc_idcache_del_by_context into the
811 lib/silccore/idcache.[ch].
813 * Changed the server's ID list routines to use the new ID Cache
814 interface. Changes around the source tree.
816 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
818 * Added silc_hash_table_del[_by_context]_ext functions in to the
819 lib/silcutil/silchashtable.[ch].
821 Removed silc_hash_table_find_all* routines and added new
822 silc_hash_table_find_foreach to replace them.
824 Added silc_hash_table_replace_ext function as extended
825 replacing function. Separated the simple hash table interface
826 from the extended hash table interface in the file
827 lib/silcutil/silchashtable.h.
829 * Fixed minor bugs and changed it to use some of the new
830 hash table functions in lib/silccore/idcache.c
832 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
834 * Added new function silc_hash_table_find_all to return all keys
835 in the hash table by the specified key. As the hash table is
836 collision resistant it also makes it possible to have several
837 duplicate keys in the hash table. This function may be used to
838 find all of the keys from the hash.
840 Added user_context arguments to the SilcHashFunction,
841 SilcHashCompare and SilcHashDestructor to deliver user specified
844 Added new fuctions silc_hash_table_find[_all]_ext to do
845 extended lookup with specified hash and compare functions and
846 specified user contexts.
848 Added new function silc_hash_table_add_ext to add the key
849 with specified hash function and user context.
851 Added new function silc_hash_table_foreach to traverse all
852 entrys in the hash table. Added SilcHashForeach callback
855 Added new function silc_hash_table_del_by_context to delete
856 the entry only if the context associated with the key matches.
858 Affected files are lib/silcutil/silchashtable.[ch].
860 * Removed silc_hash_[server/client/channel]_id and added just
861 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
862 silc_hash_id_compare to compare two ID's using as the hash table
863 comparison function. Added also silc_hash_data to hash
864 binary data and silc_hash_data_compare to compare it.
866 * Removed silc_idlist_find_client_by_hash as it is not needed
867 anymore. Affected file silcd/idlist.[ch].
869 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
870 to use internally the SilcHashTable. The new ID Cache is a lot
871 faster than the old one. Some of the ID Cache interface was also
872 rewritten and obsolete and stupid functions were removed.
874 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
876 * Added entry_count field to the SilcHashTable to keep the number
877 of the entries in the table. Implemented the function
878 silc_hash_table_rehash. Added new function
879 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
881 Fixed a minor bug in silc_hash_table_free.
883 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
884 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
885 into the lib/silcutil/silcutil.[ch].
887 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Implemented a collision resistant hash table into the
890 lib/silcutil/silchashtable[ch]. See the header and the source
891 for the SilcHashTable API.
893 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
895 * Merged dotconf version 1.0.2 into lib/dotconf.
897 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
899 * Do not compile anything in lib/silcsim/* if the SIM support
900 is not enabled. The tree should now compile without problems
903 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Compiled the SILC under cygwin. Compiled and tested briefly
906 without problems. More tests needed. The SIMs didn't compile
909 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
911 * Fixed possible crash in silc_get_username in the
912 lib/silcutil/silcutil.c.
914 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Fixed a va_arg in silc/client_ops.c.
918 * Oops, RC5 routines were named AES and caused some problems
919 when not using SIM's. Affected file lib/silccrypt/rc5.c.
921 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
923 * Added new SilcIDIP structure into the lib/silccore/id.h and
924 replaced the old `ip' fields from all SILC ID's to that type.
925 This is a step towards IPv6 support.
927 The silc_id_get_len takes now the ID as an extra argument.
928 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
929 both IPv4 and IPv6 based ID's.
931 The affected files are lib/silccore/id.[ch] and other files
932 around the tree using these routines.
934 * Removed the ID length arguments in server from various
935 silc_server_send_notify_* routines -> they are not needed
938 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * Fixed memory leak in silc_encode_pem_file in the file
941 lib/silcutil/silcutil.c.
943 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Check minor version as well in the SKE. Affected files are
946 silcd/protocol.c and lib/silcclient/protocol.c.
948 * Added --identifier option to the server so that an identifier
949 can be when creating the public key for the server. Affected
950 file is silcd/silcd.c.
952 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
953 lib/silccrypt/silcpkcs.c.
955 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
957 * Register default ciphers and stuff when using -C option with
958 the server. Affected file sildc/silcd.c.
960 * Put back the servers public key filename format, it is better
961 than the new one. For now, the client keys are saved with the
962 new filename format. The affected file silc/client_ops.c.
964 * Implemented the Cipher API for the rest of the ciphers that
965 did not implement it or implemented it the wrong way.
967 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Register default ciphers and stuff when using the -S option
970 in the client. Affected file silc/silc.c. Same also when
971 creating new key pair with -C option.
973 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
975 * Fixed the silc_verify_public_key client operation function to
976 save the public keys differently. The fingerprint is now
977 used as filename and not the hostname. This way also the
978 client keys are saved uniquely and not with hostnames. The
979 affected file is silc/client_ops.c.
981 * Trimmed the silc_hash_fingerprint function to remove extra
982 whitespaces from the end of the fingerprint. The affected
983 file is lib/silccrypt/silchash.c.
987 * Added silc_cipher_register_default function to register all
988 default ciphers. It can be used when configuration files
989 does not exist and the application does not want any specific
990 ciphers in any specific order.
992 The SilcDList is now used as silc_cipher_list dynamically
993 allocated cipher list. Removed the static list all together
994 and now all ciphers must be allocated to the dynamic list.
995 The silc_cipher_alloc routine was changed to check only the
998 All silc_cipher_* routines that used to return int returns
1001 The affected files lib/silccrypt/silccrypt.[ch].
1003 * The same thing was done to silc_hash_* as for silc_cipher_*
1004 routines. Affected files lib/silccrypt/silchash.[ch].
1006 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1007 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1008 Added also silc_pkcs_[un]register[_default] functions.
1009 Removed the data_context from the PKCS API.
1011 * Added silc_hmac_register_default function to register default
1012 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1013 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1014 to unregister all hmacs at once.
1016 * Register the default ciphers, hash functions, PKCSs and HMACs
1017 if client's configuration file does not exist. The affected
1020 * The client did not load the hash functions from the SIM
1021 modules at all. Added support for this. Affected file is
1022 silc/clientconfig.c.
1024 * When decoding public key with silc_pkcs_public_key_decode, check
1025 the supported algorithm only if PKCS are registered. Affected
1026 file lib/silccrypt/silcpkcs.c. The same was done with the
1027 silc_pkcs_private_key_decode.
1029 * Fixed the SILC List routines to keep the list always in order.
1030 It used to change the list's order when traversing the list but
1031 not it preserves the order. Affected file lib/trq/silclist.h.
1033 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Added the client library to use the SilcSocketConnection's
1036 reference counter (by silc_socket_dup) to prevent the bug that
1037 the socket object may be freed underneath async operation.
1039 * The name resolv library checking fixes in the configure.in.pre.
1042 * Created new version of the protocol drafts for future
1043 development. The -03 drafts are the ones that will be changed
1044 in the trunk now and the -02 will remain as they are.
1046 * Send list of CUMODE notifys to the router when announcing
1047 the channel users to the router. Affected file silcd/server.c.
1048 If the router receiving channel founder CUMODE for a channel
1049 that already has channel founder it will send CUMODE notify
1050 to the sender to remove the channel founder rights from the
1051 announced client. Affected file silcd/packet_receive.c.
1053 * The CUMODE notify may now use Server ID as well as the entity
1054 who changes the mode. Updated protocool specs.
1056 * Updated INSTALL and README files.
1058 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1060 * New web pages in the http://silc.pspt.fi. The pages was
1065 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1067 * Implemented the [DenyConnectin] config section in the server.
1068 Added silc_server_config_denied_conn to check whether incoming
1069 connection is denied. Affected file silcd/serverconfig.[ch].
1071 * Do not check the ports when checking the incoming configuration
1072 data if the port is 0, meaning any. Affected file is
1073 silcd/serverconfig.c.
1075 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1077 * Fixed buffer overflow in silc_string_compare in the file
1078 lib/silcutil/silcutil.c.
1080 * Fixed double free in silc_server_command_leave in the file
1083 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1085 * Fixed the version checking in the server. Affected file is
1088 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1090 * Fixed the configuration data fetching when accepting new
1091 connections in the server. Affected file silcd/server.c.
1093 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Added `sender_entry' argument to the function
1096 silc_server_packet_relay_to_channel so that we can check
1097 whether some destination actually belongs to the same route
1098 the sender belongs (ie, we must not resend the packet to the
1099 sender). Affected file silcd/packet_send.[ch].
1101 * Added `servername' field to the SilcClientEntry in the server
1102 to hold the name of the server where client is from. Affected
1103 file is silcd/idlist.h.
1105 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1107 * Moved the channel message encrypting in the router betwen
1108 router connections from silc_server_channel_message to the
1109 silc_server_packet_relay_to_channel since we want to check
1110 whether we have anybody channel before encrypting anything.
1111 Affected files silcd/packet_[receive/send].c.
1113 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1115 * Fixed the [AdminConnection] server config section to support
1116 multiple entries. Affected file silcd/serverconfig.c.
1118 * Added support into the server to check the validity of the
1119 incoming connection before executing any KE or authentication
1122 * The connection configuration is now saved to the KE and
1123 connection auth protocol contexts and not fetched anymore in
1124 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1126 * The local hosts listenning address and port is also resolved
1127 now when starting the server. We want to have the socket object
1128 to include the real address and port for the listener. Added
1129 new function silc_net_check_local_by_sock into the files
1130 lib/silcutil/silcnet.[ch].
1132 * Fixed a broadcast bug in server -> do not broadcast if we
1135 * Fixed a routing bug. Do not route broadcast packets ever.
1136 Broadcast packets must be processed always and not routed since
1137 they may be destined to some other host than yourself and thus
1138 would get routed without no good reason. Affected file is
1141 * Added function silc_server_config_is_primary_route to check
1142 whether primary router connection has been configured (a router
1143 configuration that we are initiating). If there is not, we
1144 will assume that there is only two routers in the SILC network
1145 and we will use the incoming router connection as our primary
1146 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1148 * Changed the order of the broadcasting. Broadcast _after_ the
1149 packet has been processed not before. Affected file is
1152 * Fixed a [ClientConnection] parsing bug. The port was never
1153 parsed correctly thus resulting to port 0. Affected file
1154 silcd/serverconfig.c.
1156 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1157 argument and did not set the broadcast packet flag. Affected
1158 file silcd/packet_send.c. Fixed same bug in the function
1159 silc_server_send_notify as well.
1161 * If we receive NEW_ID packet for our own ID in the server, ignore
1164 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1168 * Removed the nickname from the Private Message Payload.
1169 Updated the code and the protocol specs.
1171 * Updated protocol specs for submitting to the IETF.
1173 * Tweaked the Random Number Generator a bit. Affected file
1174 lib/silccrypt/silcrng.c. Exported a new function
1175 silc_rng_[global]_add_noise which can be used to add more
1178 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1180 * Do not parse packets with different timeout when protocol
1181 is active -> may cause problem with rekey. Affected file
1184 * When server receives signoff notify it must not create
1185 new channel key if the client is on any channels since the
1186 sender of the signoff notify will create it.
1188 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Added printing of error messages during SKE protocol from the
1191 failure packet sent by server during SKE. Affected file
1194 * Removed the client's failure_callback handling with timeout
1195 and handle it immediately when received.
1197 * The SKE library returned wrong type in SUCCESS and FAILURE
1198 packets. They must be 32 bit MSB not 16 bit MSB.
1200 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Ok, rewrote the logic of the re-key and now it seems to work.
1203 I tested it on high traffic with frequent re-keys without
1204 problems. Added hmac_receive (and renamed hmac to hmac_send)
1205 in SilcClientConnection in lib/silcclient/client.h and
1206 in SilcIDListData in silcd/idlist.h. Also, removed the
1207 SilcPacketParserContext's cipher and hmac fields as they are
1208 not needed anymore and actually caused some problems when
1209 the ciphers and hmac's changed underneath the packet parser.
1211 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * If re-key protocol is active then process the incoming packets
1214 synchronously since we must assure that icoming packets encrypted
1215 with the old key is processed before the new keys is set to
1216 use. This is true other packets than for REKEY packets.
1217 Affected file silcd/server.c. The same was done to client library
1218 as well, affected file lib/silcclient/client.c.
1220 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1222 * Fixed bug in client and server to accept the force send if
1223 the packet is send from silc_[server/client]_packet_process
1224 function. Otherwise the packets are never delivered, oops.
1226 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1228 * Disable force sending of packets when REKEY protocol is active.
1229 We must assure that no packet is sent directly when rekey is
1230 performed. All packets must be sent through packet queue.
1231 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1232 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1233 function is silc_[server/client]_packet_send_real to check
1236 * Replaced the SIM paths from example config files to
1237 /usr/local/modules. Also, make install creates now
1238 /usr/local/silc/logs directory to hold all the SILC server
1241 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1243 * Made the configure.in.pre work on Solaris. Patch by salo.
1245 * Made all ciphers compatible with non-x86 machines. Defined
1246 CBC mode macros into lib/silccrypt/ciphers_def.h.
1248 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1250 * Fixed the make install.
1252 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * When MAC computation fails the silc_packet_decrypt returned 0
1255 even though it was supposed to return -1. Fixed this. The
1256 affected file is lib/silccore/silcpacket.c.
1258 * Do not replace the config files in /etc/silc (in make install)
1259 if they already exist. Affected file ./Makefile.am.
1261 * Do not send re-key packets immediately but through packet queue.
1262 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1264 * Changed silc_net_check_host_by_sock to return FALSE if the
1265 IP/DNS could not be resolved. Though, it returns the IP address
1266 now even if it could not resolve it (but returns also FALSE).
1267 Affected file lib/silcutil/silcnet.[ch].
1269 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Added silc_pkcs_decode_identifier to decode the public key's
1272 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1273 Added also silc_pkcs_free_identifier. Added also new context
1274 SilcPublicKeyIdentifier.
1276 * Added -S option to the silc client. It is used to dump the
1277 contents of the specified public key file.
1279 * Changed the PKCS api to return the public key length when
1280 setting the public key.
1282 * Fixed a fatal bug in the public and private key file loading.
1283 Affected file lib/silccrypt/silcpkcs.c.
1285 * Execute the packet parsing for client with zero (0) timeout
1286 if the protocol is active. Affected file silcd/server.c.
1288 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1290 * Made the key generation options to the silcd program. Added
1291 -C option, equivalent to client's option.
1293 * Added new [ServerKeys] config section to the server. It
1294 configures the server's public and private key.
1296 * Defined generic Public Key Payload into the protocol
1297 specification to send specific type of public keys and
1300 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1301 public key or certificate.
1303 * Implemented the GETKEY command to the server and to the
1304 client library and on user interface.
1306 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1308 * Made preliminary `make install' work.
1310 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1312 * Added SilcServerRekey context into silcd/idlist.h.
1314 * Added the PFS support as defined in the specification to the
1315 SKE protocol. Affected files lib/silcske/*.c.
1317 * Added `ske_group' field to the SilcServerRekey context to hold
1318 the number of the SKE group that is used with PFS in re-key.
1319 Affected file silcd/idlist.h.
1321 * Added PFS re-key support to the server. Affected file is
1324 * Added silc_protocol_cancel to cancel execution of the next
1325 state of the protocol. Affected file is
1326 lib/silccore/silcprotocol.[ch].
1328 * Added the re-key support with and without PFS to the client
1329 library. Re-key is performed once in an hour, by default.
1331 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1332 Added silc_client_rekey_callback and silc_client_rekey_final.
1333 Affected files are lib/silcclient/protocol.[ch] and
1334 lib/silcclient/client.[ch].
1336 * Removed the `hmac_key' and `hmac_key_len' fields from the
1337 SilcClientConnection structure; not needed. Affected file is
1338 lib/silcclient/client.h.
1342 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1344 * Do not ask whether user wants to use the negotiated private key
1345 for private messages, just use it. Affected file is
1346 silc/local_command.c.
1348 * Added `send_enc_key' and `enc_key_len' fields to the
1349 SilcIDListData structure since they are needed in the re-key
1350 phase. Affected file is silcd/idlist.[ch].
1352 * Implemented the simple re-key protocol into the server.
1353 Affected files silcd/server.c and silcd/protocol.[ch]. The
1354 re-key will be performed once in an hour, by default.
1356 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1357 Added silc_server_rekey, silc_server_rekey_callback and
1358 silc_server_rekey_final.
1360 * Removed Tunneled flag from the protocol. Updated the code
1361 and the specifications.
1363 * Adde `pfs' field to the SilcIDListData to indicate whether
1364 the PFS is to be performed in the re-key. Affected file is
1367 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1369 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1370 int64 of at least the xintXX size. If void * is less that 4
1371 bytes uint32 * will be used. Defined bool as boolean.
1373 * Changed _ALL_ unsigned long and unsigned int to uint32,
1374 unsgined short to uint16 in the source tree.
1376 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1377 not handle clients that has entry->data.registered == FALSE.
1378 They are not in the network anymore. Affected file is
1381 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Implemented the sending of the SERVER_SIGNOFF notify in the
1384 server. Affected file is silcd/server.c.
1386 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1387 Added also silc_notify_payload_encode_args into the
1388 lib/silccore/silcnotify.[ch].
1390 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1391 Affected file silcd/packet_receive.c.
1393 * Implemented the SERVER_SIGNOFF notify handling in the client
1394 library. Affected file lib/silcclient/client_notify.c. Also,
1395 implemnted the printing of the SERVER_SIGNOFF info to the
1396 application. Affected file silc/client_ops.c.
1398 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1399 if the deleting was successful. Affected file silcd/idlist.[ch].
1401 * Added support for public key authentication in the connection
1402 authentication protocol in the client library. Affected file
1403 lib/silcclient/protocol.c.
1405 * Changed the server's silc_idlist_get_clients_by_* interface
1406 to support already allocated array so that new entries may be
1407 added to pre-allocated array. Affected file silcd/idlist.[ch].
1408 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1409 and command replies.
1411 * All command reply functions in the server now calls the
1412 pending command callback even if error occured. This way the
1413 error will be delivered to the client as well. Affected files
1414 silcd/command.c and silcd/command_reply.c.
1416 * Fixed INFO command to return local server's info if no server
1417 was provided. Affected file lib/silcclient/command.c.
1419 * Removed RESTART command for good. Updated the code and the
1422 * Rewrote parts of the task system. It is a bit simpler now.
1423 Removed unsued task priorities. The affected files are
1424 lib/silcutil/silctask.[ch].
1426 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Moved the USERS printing from the library to the application.
1429 Affected files lib/silcclient/command.c and silc/client_ops.c.
1431 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1435 * Added channel key re-key support. The re-key is perfomed
1436 only by the router and is done once in an hour. Added `rekey'
1437 field to the SilcChannelEntry in the server. Affected files
1438 silcd/server.c and silcd/idlist.h.
1440 * Added silc_task_unregister_by_context into the file
1441 lib/silcutil/silctask.[ch].
1443 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1445 * Added SILC_UMODE_GONE mode to indicate when the client is not
1446 present in the SILC network. Added also support to the local
1447 command AWAY that will set this mode. Added support of showing
1448 "xxx is gone" in WHOIS command. The USERS command shows the
1449 gone status as well.
1451 * Fixed setting server and router operator privileges in the
1452 server's UMODE command. Affected file silcd/command.c.
1454 * Merged the SKE KE1 and KE2 payloads into one payload. The
1455 new KE payload is equivalent to the old KE2 payload.
1457 Cleaned up the SKE Start Payload parsing. It now uses the
1458 simple buffer unformatting to do the parsing. A lot faster
1461 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1462 to the SKE that is used to indicate whether both of the SKE
1463 parties should perform authentication. By default only the
1464 responder performs authentication. By setting this flag also
1465 the initiator must do authentication. By default it is unset
1466 since in normal SKE case, client to server connection, only
1467 the responder should do authentication. When doing SKE between
1468 two clients both should perform authentication. Updated the
1469 code and the protocol specs.
1471 * A little fix to IDENTIFY command in the server. Search the
1472 client first by hash not nickname. Affected file is
1475 * Fixed the silc_client_close_connection to support closing
1476 the client to client connections wihtout deleting too much
1477 data. Affected file lib/silcclient/client.c.
1479 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1480 are received if protocol used to be active but is not anymore
1481 the application would crash due to NULL pointer dereference.
1482 Affected files silcd/server.c and lib/silcclient/client.c.
1484 * Added `hash' field to the SilcClientConnection to include
1485 the hash function negotiated in the SKE protocol.
1487 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1488 to set the channel founder authentication data. A client can
1489 claim the founder rights later by providing the authentication
1490 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1491 This way the channel founder can regain the channel founder
1492 privileges even it is left the channel. This works only on
1493 local server and the client must be connected to the same
1494 server to be able to regain the founder rights. Updated the
1495 protocol specs accordingly.
1497 Added support to the CMODE command in the client to set the
1498 founder auth data. Read the README to see how to set it.
1500 Added support to the CUMODE command to claim the founder
1501 rights. Read the README to see how to do it.
1503 Added support for the founder authentication to the Channel
1504 Entry in the server. Affected file silcd/idlist.h.
1506 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1507 server's CMODE command. Affected file silcd/command.c.
1509 * Added the following new functions into lib/silccore/silcauth.[ch]:
1510 silc_auth_get_method and silc_auth_get_data.
1512 * The server now saves the remote hosts public key to the
1513 SilcIDListData pointer. Affected file silcd/protocol.c.
1515 * The normal server now does not remove the channel entry from
1516 the cache if the founder authentication data is set. It used
1517 to remove it if the founder was the last one on the channel on
1518 the server and left the channel. The auth data is saved and
1519 if the channel is re-joined later the old entry is used with
1520 the old auth data. Affected files silcd/command_reply.c and
1523 * Removed the `pkcs' field from the SilcIDListData structure
1524 in the server; it is not used. Affected file silcd/idlist.h.
1526 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Fixed packet processing on slow links. Partial packets were
1529 never re-processed because the incoming data buffer was cleared
1530 by the application. Application must not directly clear the
1531 sock->inbuf, the packet processing routines handle it. Fixed
1532 this in client library and in server.
1534 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1536 * Fixed the WHOIS and IDENTIFY send reply function to really
1537 check whether to send list or just one entry. Affected file
1540 * Cleaned up the LEAVE command's channel key distribution. The
1541 affected file silcd/command.c.
1543 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1544 can enforce the channel mode as well. In that case the ID
1545 includes the ID of the server. The code now enforces the
1546 mode change if the router have different mode than the server.
1548 * The notify client operation with CMODE_CHANGE notify can now
1549 return NULL client_entry pointer if the CMODE was not changed
1550 by client. Application must check for this.
1552 * Added <Server ID> argument to INFO command to support server
1553 info fetching by Server ID.
1555 * Added silc_server_announce_get_channel_users to get assembled
1556 packets of channel users of the specified channel. Affected
1557 file silcd/server.[ch].
1559 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1560 was freed underneath the ID Cache.
1562 * Re-announce clients when the server received CHANNEL_CHANGE
1563 notify from the router. Affected file silcd/packet_send.c.
1565 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1567 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1568 crashed since it did not handle the fact that there is no cipher
1569 called "3" and didn't check the error condition. Now fixed.
1571 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1572 flag. It can be used to send message requests.
1574 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Implemented the RESTART command in the client.
1578 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1579 notice type messages. Added notice printing to the user
1582 * The channel keys are not re-generated if the channel's mode
1583 is PRIVKEY, ie private key on the channel exists. Affected
1584 files silcd/server.c and silcd/command.c.
1586 * Fixed a little bug in channel message delivery when channel
1587 private keys are set in the server. Affected file is
1588 silcd/packet_send.c.
1590 * Changed the setting on channel->on_channel = TRUE from the
1591 silc_client_save_channel_key to the JOIN command reply. The
1592 key payload is not received if the private channel key is set.
1593 Affected file lib/silcclient/command_reply.c and the
1594 lib/silcclient/client_channel.c.
1596 * When the CMODE_CHANGE notify is sent and the channel private
1597 key mode is removed the channel key must be re-generated in
1598 other cells as well. Added this support for the router in the
1599 silcd/packet_receive.c.
1601 * Added new local command NOTICE to send notice message on
1602 channel. Affected file silc/local_command.[ch].
1604 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1606 * Added new local command ME to the client. It is used to send
1607 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1608 some action. Affected file silc/local_command.[ch].
1610 * Changed channel_message and private_message client operations
1611 to deliver the message flags to the application. Added also
1612 the `flags' arguments to the silc_client_send_channel_message
1613 and silc_client_send_private_message functions. Affected file
1616 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1618 * Redefined the Private Message Payload to support private message
1619 keys and to support the new private message flags. Updated
1620 the protocol specs. Flags makes it possible to have for example
1621 CTCP style messages.
1623 * Added new type SilcPrivateMessagePayload and defined an API
1624 for it in the lib/silcclient/silcprivate.[ch].
1626 * Tested private message private keys successfully. Tested the
1627 private message key set, unset and list commands with the new
1630 * Redefined the Channel Message Payload to include the channel
1631 message flags (equal with private message flags) to support
1632 for example CTCP style messages.
1634 * Defined some of the message (for channel and private message)
1635 flags. Updated the protocol specs and added the flags to the
1636 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1638 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1640 * Added SilcKeyAgreementStatus type to the key agreement routines
1641 to indicate the current status and error if one occured.
1642 The status types are defined in the lib/silcclient/silcapi.h.
1644 * Added new local command KEY that is used to set and unset private
1645 keys for channels, set and unset private keys for private messages
1646 with remote clients and to send key agreement requests and
1647 negotiate the key agreement protocol with remote client. The
1648 key agreement is supported only to negotiate private message keys,
1649 it currently cannot be used to negotiate private keys for channels,
1650 as it is not convenient for that purpose.
1652 * Fixed a minor pending callback setting bug in the function
1653 silc_client_get_client_by_id_resolve, now the function works.
1654 Affected file lib/silcclient/idlist.c.
1656 * Added function silc_net_get_local_port to get local bound
1657 port by socket. Added to lib/silcutil/silcnet.[ch].
1659 * Added `sockets' and `sockets_count' fields to the SilcClient
1660 object. They hold the sockets of the listenning sockets in
1661 the client. Listenning sockets may be for example the key
1662 agreement server. Affected file lib/silcclient/client.[ch].
1663 Added functions the silc_client_add_socket and the
1664 silc_client_del_socket. They are exported to the application
1667 * Added ~./silc/clientkeys to support other client's public keys.
1669 * Renamed verify_server_key client operation to verify_public_key
1670 and added one argument to indicate the type of the connection
1671 (server, client etc.).
1673 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1675 * Added silc_server_connection_auth_request to handle the
1676 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1677 silcd/packet_receive.[ch].
1679 * Added silc_server_send_connection_auth_request into the
1680 silcd/packet_send.c to send the connection auth request packet.
1682 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1685 * Fixed the public key authentication in responder side in the
1686 server. The `auth_data' pointer includes the SilcPublicKey
1687 not the path to the public key. Affected file silcd/protocol.c.
1689 * Implemented the public key authentication in the initiator side
1690 in the server. Affected file silcd/protocol.c.
1692 * Removed the [RedirectClient] config section from the server
1693 configuration. Is not needed and I don't want to implement it.
1695 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1697 * Cleaned up the CMODE command in the server. It now works
1698 correctly and supports all the modes defined in the protocol.
1699 Affected file is silcd/command.c.
1701 * Added `hmac_name' field to the SilcChannelEntry in the server
1702 to hold the default HMAC of the channel. It can be set when
1703 creating the channel (with JOIN command). Affected files
1706 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1707 type to indicate the change of the current cipher and hmac
1708 on the channel. Client can safely ignore the <cipher> argument
1709 (if it chooses to do so) since the CHANNEL_KEY packet will
1710 force the channel key change anyway. The <hmac> argument is
1711 important since the client is responsible of setting the new
1712 HMAC and the hmac key into use.
1714 * Fixed the CMODE command in the client library as well.
1716 * Tested CMODE command in router environment successfully.
1718 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * Show the version of the remote client (or server) when connecting
1721 to the server. It is logged to the log file. Affected file
1722 is silcd/protocol.c.
1724 * Fixed the KILLED notify handling in the client library. The
1725 client must be removed from all channels when receiving the
1728 Also, do not remove the client entry when giving the KILL
1729 command but when the KILLED notify is received.
1731 * Removed silc_idlist_find_client_by_nickname from the server.
1732 Not needed anymore. Affected files silcd/idlist.[ch].
1734 * Implemented the CHANNEL_CHANGE notify type handling to the
1735 server. Affected file silcd/server.c.
1739 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Added silc_server_send_notify_invite to send the INVITE
1742 notify between routers.
1744 * Implemented the INVITE command correctly to the server.
1746 * Implemented the INVITE notify type handling in the server.
1748 * Implemented the INVITE command to the client library and on the
1751 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1753 * Added function silc_server_get_client_resolve to find the
1754 client entry by ID from all ID lists and then resolve it
1755 (using WHOIS) if it cannot be found. Affected file is
1758 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1760 * Implemented the BAN command to the client library.
1762 * The JOIN command in the server now checks the invite list
1765 * Changed the silc_command_reply_payload_encode_va and the
1766 silc_command_payload_encode_va to support that if argument is
1767 NULL it ignores and checks the next argument. Affected file
1768 lib/silccore/silccommand.c.
1770 * Added silc_server_send_notify_ban to send the BAN notify
1771 type between routers.
1773 * Chaned the silc_notify_payload_encode to support that if
1774 argument is NULL it ignores and checks the next argument.
1775 Affected file lib/silccore/silcnotify.c.
1777 * Tested ban lists in router environment successfully.
1779 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1781 * Implemented BAN command to the server, in silcd/command.[ch].
1783 * Removed the BAN and INVITE_LIST modes from the CMODE command
1786 * Added function silc_string_match to regex match two strings.
1787 Affected files lib/silcutil/silcutil.[ch].
1789 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1791 * Redefined parts of the SilcChannelEntry in the server to support
1792 the new ban and invite lists.
1794 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1796 * Redefined the INVITE command. The same command can be used to
1797 invite individuals to the channel but also to manage the invite
1798 list of the channel (to add to and remove from the invite list).
1799 Updated the protocol specs.
1801 * Added new command SILC_COMMAND_BAN that can be used to manage
1802 the ban list of the channel. Updated the protocol specs.
1804 * Removed the channel modes: the SILC_CMODE_BAN and the
1805 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1806 in the CMODE command. The equivalent features are now available
1807 using INVITE and BAN commands. Updated the protocol specs.
1809 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1810 in the network about change in the current ban list. The notify
1811 type is not used by the client.
1813 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1814 support the invite lists.
1816 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Added new function silc_string_regexify that converts string
1819 including wildcard characters into regex string that can
1820 be used by the GNU regex library. Added into the file
1821 lib/silcutil/silcutil.[ch].
1823 Added silc_string_regex_combine to combine to regex strings
1824 into one so that they can be used as one regex string by
1825 the GNU regex library. Added into the file
1826 lib/silcutil/silcutil.[ch].
1828 Added silc_string_regex_match to match two strings. It returns
1829 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1831 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1833 * Imported GNU regex to the soruce tree into lib/contrib.
1834 Fixed some compiler warning from the regex.c.
1836 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1838 * Fixed MOTD command in the server to work in router environment.
1840 * Fixed the MOTD command in the client library to support
1841 the server argument in the command.
1843 * Added `nickname_len' argument to the silc_idlist_add_client
1844 in the server, as the `nickname' argument may be binary data
1847 * Added silc_idlist_get_channels to return all channels from
1850 * Implemented LIST command to the server. Affected file is
1853 * Implemented the LIST command to the client library and on the
1856 * Added [<user count>] argument to the LIST command reply.
1857 With private channels the user count is not shown.
1859 * Updated TODO and README.
1861 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1863 * The client entry's data.registered must be TRUE even with
1864 global client entry on global client list. The data.registered
1865 is used to check whether the client is anymore in the network,
1866 for example with WHOWAS command so it must be valid.
1868 * Fixed the WHOWAS command in the server. It now actually works
1869 in router environment. Added function into silcd/command_reply.c
1870 silc_server_command_reply_whowas_save.
1872 * Added silc_idlist_purge function to the silcd/idlist.c
1873 to periodically purge the ID Cache.
1875 * Fixed INFO command in the server. It works now in router
1876 environment. Added <server name> argument to the INFO command
1877 reply. Updated the protocol specs.
1879 * Fixed minor bug in silc_idcache_purge to not purge if the
1880 expire value is zero.
1882 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1883 they were buggy because of the WHOWAS information.
1885 * Fixed local command MSG to handle the async resolving of
1886 the remote client properly. It used to fail the first MSG.
1887 Affected file silc/local_command.c.
1889 * Added `data_len' field to SilcIDCache context.
1891 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * Update TODO. Todo in commands in the server.
1895 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1898 used by routers as broadcast packet to inform other routers
1899 about the changed user mode.
1901 Implemented the notify handling in the server. Affected file is
1902 silcd/packet_receive.c. Added the function
1903 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1905 * Added new generic Channel Payload and deprecated the New Channel
1906 Payload. The New Channel Payload is now the generic Channel
1909 * Added new argument `mode' to the silc_server_send_new_channel
1910 as it is required in the Channel Payload now.
1912 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1913 and created a new and real SilChannelPayload to represent the
1914 new generic Channel Payload. Implemented the encode/decode
1915 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1917 * Added silc_server_get_client_channel_list to return the list
1918 of channels the client has joined for WHOIS command reply.
1919 Affected file silcd/server.[ch].
1921 * Implemented the channel list sending in the WHOIS command reply
1922 in server and in the client.
1924 Implemented the channel list displaying on the user interface
1925 as well. Affected file silc/client_ops.c.
1927 * Added silc_channel_payload_parse_list to parse list of Channel
1928 Payloads. It returns SilcDList list of SilcChannelPayloads.
1929 Client for example can use this function to parse the list of
1930 channels it receives in the WHOIS command reply. The caller
1931 must free the list by calling silc_channel_payload_list_free.
1932 Affected files lib/silccore/silcchannel.[ch].
1934 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * Added one new argument <user mode> to the WHOIS command reply
1937 to return the mode of the user in SILC. Updated the protocol
1940 Implemented it to the server and client.
1942 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1944 * Fixed the mode printing on the user interface on joining.
1945 Affected file silc/client_ops.c.
1947 * Implemented the UMODE command and user modes in general to the
1948 client library and to the user interface.
1950 * Implemented the UMODE command to the server.
1952 * The server now sends UNKNOWN_COMMAND error status if client sends
1953 unknown command. Affected file silcd/command.c.
1955 * All server commands now handle the command identifier the right
1956 way when sending the command reply to the client. The client can
1957 use to identify the command replies with the identifier.
1959 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1961 * Added silc_server_get_client_route to resolve the route to
1962 the client indicated by the client ID. Affected file is
1965 * Added silc_server_relay_packet as general function to relay
1966 packet to arbitrary destination. This deprecates functions
1967 like _send_private_message_key, _relay_notify etc. Affected
1968 file is silcd/packet_send.[ch].
1970 Removed silc_server_send_key_agreement,
1971 silc_server_send_private_message_key and
1972 silc_server_packet_relay_notify functions from the file
1973 silcd/packet_send.[ch].
1977 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1978 server. Affected file silcd/packet_receive.[ch].
1980 * Implemented the KILL command to the client. Implemented the
1981 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1982 Affected files lib/silcclient/command[_reply].c and
1983 lib/silcclient/client_notify.c. Implemented the KILL notify
1984 printing in the user inteface.
1986 * Fixed a lot silc_parse_nick memory leaks from the client
1987 library in the file lib/silcclient/command.c.
1989 * Changed the silc_server_send_notify_on_channels's `sender'
1990 argument from SilcSocketConnection to SilcClientEntry to
1991 check the sender as entry and not as connection object and not
1992 to send to the client provided as argument. The affected file
1993 is silcd/packet_send.[ch].
1995 * The notify packets that are destined directly to the client used
1996 to not to be processed by the server. Now changed that and the
1997 server processes all notify packets. After relaying the packet
1998 to the client the notify packet is processed in the server.
2000 * The silc_server_free_client_data now checks whether there is
2001 pending outgoing traffic for the client and purges the data to
2002 the network before removing the client entry.
2004 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2006 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2007 an client is killed from the SILC Network. Updated the protocol
2010 Added new function silc_server_send_notify_killed to the
2011 silcd/packet_send.[ch].
2013 * Added function silc_server_packet_relay_notify to relay notify
2014 packets that are destined directly to a client. In this case
2015 the server does not process the notify packets but merely relays
2016 it to the client. Affected file silcd/packet_send.[ch].
2018 Added also silc_server_packet_process_relay_notify to check
2019 whereto relay the notify. Affected file is
2020 silcd/packet_receive.[ch].
2022 * Implemented the KILL command to the server.
2026 * Added the backup schema desgined last fall to the protocol
2027 specs for everyone to see. The specification is in the
2028 *-spec-xx.txt draft and the packet type definitions for the
2029 backup routers is in *-pp-xx.txt draft. Thusly, added also
2030 new packet type SILC_PACKET_CELL_ROUTERS.
2032 * A big security problem in the implementation discovered. The
2033 signoff of an client did not cause new channel key generation
2034 which it of course should've done. The channel keys must be
2035 always re-generated when client leaves (or signoffs) the channel.
2036 The silc_server_remove_from_channels funtion now handles
2037 the channel key re-generation.
2039 * Added `sender' argument to the silc_server_send_notify_on_channels
2040 to not to send the client provided as argument. Affected file
2041 silcd/packet_send.[ch].
2043 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2045 * Implemented OPER and SILCOPER commands into the server and
2048 * Added silc_auth_verify and silc_auth_verify_data to verify
2049 the authentication directly from the authentication payload.
2050 It supports verifying both passphrase and public key based
2051 authentication. Affected file lib/silccore/silcauth.[ch].
2053 * Added `hash' field to the SilcIDListData structure. It is the
2054 hash negotiated in the SKE protocol. Affected file is
2057 * Slight redesigning of the SilcAuthPayload handling routines.
2058 Do not send SilcPKCS but SilcPublicKey as argument.
2060 * Implemented the public key authentication support to the
2061 serverconfig. The public key is loaded from the provided path
2062 and saved as authentication data to void * pointer. Thus,
2063 changed the unsigned char *auth_data to void *auth_data;
2065 * Fixed SHUTDOWN command to send the reply before the server
2066 is shutdown. :) Affected file silcd/command.c.
2068 * Fixed fatal bug in CONNECT command. The hostname was invalid
2069 memory and server crashed. Affected file silcd/command.c.
2071 * Fixed fatal bug in CLOSE command. The server_entry became
2072 invalid but was referenced later in the command. Affected file
2075 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Fixed fatal bug in failure packet handling. Server ignored
2078 the failure and thus crashed when it came.
2082 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2084 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2085 that the command may be executed only once in (about) 2 seconds.
2086 The old SILC_CF_LAG flag is same but allows command bursts up
2087 to five before limiting.
2089 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2090 server code. Various commands now includes the CF_LAG_STRICT
2091 flag to disallow any kind of miss-use of the command.
2093 * Fixed the silc_buffer_unformat to not to allocate any data
2094 if the length of the data is zero. It used to allocate the
2095 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2097 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Changed the format of AdminConnection configuration section
2100 in the server. Added username of the admin to the format.
2101 Affected files silcd/serverconfig.[ch].
2103 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2104 to return admin configuration data by host, username and/or
2107 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Implemented WHOWAS command to the server. Added the functions:
2111 silc_server_command_whowas_parse,
2112 silc_server_command_whowas_send_reply,
2113 silc_server_command_whowas_from_client and
2114 silc_server_command_whowas_from_server
2116 * Added <Client ID> argument to the WHOWAS command reply. Updated
2117 the protocol specs accordingly.
2119 * Implemented WHOWAS command and command_reply to the client
2122 Implemented the WHOWAS printing on the user interface.
2124 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2126 * Added new argument to the WHOWAS command reply, the real name.
2127 It is an optional argument. Updated the protocol specs.
2129 * Added SilcIDCacheDestructor callback that is registered when
2130 the SilcIDCache is allocated. The callback is called when
2131 an cache entry in the ID Cache expires, or is purged from the
2132 cache. Added into lib/silccore/idcache.[ch].
2134 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2135 to destruct the client entries when the cache entry expires.
2136 Other ID Cache's in server and in the client library ignores
2139 * If the ID Cache entry's `expire' field is zero then the entry
2140 never expires. Added boolean `expire' argument to the
2141 silc_idcache_add function in the lib/silccore/idcache.[ch].
2142 If it is TRUE the default expiry value is used.
2144 * Added silc_server_free_client_data_timeout that is registered
2145 when client disconnects. By default for 5 minutes we preserve
2146 the client entry for history - for WHOWAS command.
2148 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2150 * Added support to the server to enforce that commands are not
2151 executed more than once in 2 seconds. If server receives
2152 commands from client more frequently, timeout is registered
2153 to process the commands. Affected file silcd/command.c.
2154 Added new function silc_server_command_process_timeout.
2156 * Changed NICK_NOTIFY handling in client library to check that
2157 if the client's nickname was changed, so there is no need to
2158 resolve anything from the server.
2160 * Removed error printing from the WHOIS and IDENTIFY commands.
2161 If error occurs then it is ignored silently in the client library.
2162 The application, however, may map the received error to
2163 human readable error string. The application currently maps
2164 the NO_SUCH_NICKNAME error to string.
2166 * Made the command status message public to the application. Moved
2167 them from lib/silcclient/command_reply.c to
2168 lib/silcclient/command_reply.h. The application can map the
2169 received command status to the string with the
2170 silc_client_command_status_message function.
2172 * Added check to the server to check that client's ID is same
2173 as the Source ID in the packet the client sent. They must
2176 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Added dist-bzip hook to the Makefile.am to make bzip2
2179 compressed distributions.
2181 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Server now enforces the maximum length for the nickname and
2184 the channel as protocol specification dictates. 128 bytes for
2185 nickname and 256 bytes for channel name.
2187 * Moved the WHOIS printing to the application. The client libary
2188 does not print out the WHOIS information anymore, the application
2189 must do it. Renamed silc_client_command_reply_whois_print to
2190 the silc_client_command_reply_whois_save.
2192 The client's idle time is also sent to the application now, and
2193 the idle is shown on screen.
2195 * Added silc_client_command_reply_identify_save to save the
2196 received IDENTIFY entries.
2198 * Do not check for channel private keys in message sending and
2199 reception if the channel does not have the PRIVKEY mode set.
2200 Affected file lib/silclient/client_channel.c.
2202 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2204 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2205 just surfaced after chaning the JOIN procedure.
2207 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2209 * Added silc_client_get_clients_by_list to get client entries
2210 from Client ID list, that is returned for example by JOIN
2211 and USERS command replies. The application should use this
2212 function for example when JOIN command reply is received to
2213 resolve the clients already on the channel (library does not
2214 do that anymore as USERS command reply is not used in the JOIN
2215 procedure anymore). Affected files lib/silcclient/silcapi.h and
2216 lib/silcclient/idlist.c.
2218 * JOIN command reply and USERS command reply returns now SilcBuffer
2219 pointers instead of unsigned char pointers when returning
2220 the client list and mode list.
2222 * Added <Client ID> argument to the JOIN command reply, mainly
2223 for the server to identify for which client the command was
2224 originally sent. Updated protocol specs accordingly.
2226 * Added SilcDlist private_key pointer to the SilcChannelEntry
2227 in the client to support the channel private keys. Affected
2228 file is lib/silcclient/idlist.h.
2230 * Added SilcChannelPrivateKey argument to the function
2231 silc_client_send_channel_message so that application can choose
2232 to use specific private ke if it wants to. If it is not provided,
2233 the normal channel key is used, unless private keys are set.
2234 In this case the first (key that was added first) is used
2235 as the encryption key.
2237 * Implemented the support for channel private key handling.
2238 Implemented the following functions:
2240 silc_client_add_channel_private_key,
2241 silc_client_del_channel_private_keys,
2242 silc_client_del_channel_private_key,
2243 silc_client_list_channel_private_keys and
2244 silc_client_free_channel_private_keys
2246 Affected file lib/silcclient/client_channel.c.
2248 * Added the support for the private keys in the channel message
2249 sending and encryption and in the message reception and
2250 decryption. Affected funtions are
2251 silc_client_send_channel_message and silc_client_channel_message.
2253 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2255 * Added SKE's key verify callback to the client library's
2256 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2258 * Removed the statement that server (or router) must send USERS
2259 command reply when joining to the channel so that the client
2260 knows who are on the channel. Instead, the client list and
2261 client's mode list is now sent in the JOIN command reply to the
2262 client who joined channel. This is better solution.
2264 * Added function silc_server_get_users_on_channel and function
2265 silc_server_save_users_on_channel to the silcd/server.[ch].
2267 * Removed function silc_server_command_send_users from the
2270 * Do not show topic on the client library anymore. The topic is
2271 sent in the command reply notify to the application and the
2272 application must show the topic now.
2274 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Added client searching by nickname hash into the IDENTIFY and
2277 WHOIS commands in the server as they were clearly missing from
2278 them. Affected file is silcd/command.c.
2280 * Fixed a bug in private message receiving in the client library.
2281 The remote ID was freed and it wasn't supposed, now it is
2284 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Minor fix to the channel payload; allocate the data area, as it
2287 needs to be of specific length.
2289 * If the key agreement port is zero then the operating
2290 system will define the bound port. Affected files are
2291 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2293 * Added new function silc_channel_payload_decrypt into the file
2294 lib/silccore/silcchannel.[ch].
2296 * Moved the channel message etc, check from silc_packet_decrypt
2297 to applications. The library calls now a generic
2298 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2299 when the packet is either normal or special. This was done to
2300 allow more wide range of checking that was not allowed when
2301 the code was in library. Now applications can do virtually any
2302 checks to the packet and return to the library the decision how
2303 the packet should be processed. Affected files are
2304 lib/silccore/silcpacket.[ch].
2306 Added silc_server_packet_decrypt_check to the server and
2307 silc_client_packet_decrypt_check to the client library.
2309 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2310 to send with specified source and destination information.
2312 * Channel message delivery between routers was broken after the
2313 channel key distribution was fixed earlier. The channel key
2314 was used be to distributed to other routers as well which is not
2315 allowed by the protocol. Now this is fixed and channel keys
2316 really are cell specific and the channel message delivery between
2317 routers comply with the protocol specification.
2319 * Fixed various commands in server to check also the global list
2320 for the channel entry and not just the local list. The affected
2321 file silcd/command.c.
2323 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2325 * Added assert()s to buffer formatting and unformatting routines
2326 to assert (if --enable-debug) when error occurs. Affected
2327 file: lib/silcutil/silcbuffmt.c.
2329 * Changed to auto-reconnect to check whether the remote host is
2330 router and register the re-connect timeout if it is. It used
2331 to check that whether we are normal server, but router must do
2332 auto-reconnect with another router as well. Affected file
2335 * Removed the [<key len>] option from CMODE command as the cipher
2336 name decides the key length, nowadays. See the defined ciphers
2337 from the protocol specification.
2339 * Added [<hmac>] option to the CMODE command to define the HMAC
2340 for the channel. Added SILC_CMODE_HMAC channel mode.
2342 * Added [<hmac>] option for the JOIN command so that user can
2343 select which HMAC is used to compute the MACs of the channel
2346 * Added Hmac field to the Channel Message Payload. The integrity
2347 of plaintext channel messages are now protected by computing
2348 MAC of the message and attaching the MAC to the payload. The
2349 MAC is encrypted. Now, it is clear that this causes some
2350 overhead to the size of the packet but rationale for this is that
2351 now the receiver can verify whether the channel message decrypted
2352 correctly and also when private keys are set for the channel the
2353 receiver can decrypt the packet with several keys and check from
2354 the MAC which key decrypted the message correctly.
2356 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2357 lib/silccrypt/silccipher.[ch].
2359 * Added silc_hash_len to return the digest length into the
2360 lib/silcrypt/silchash.[ch].
2362 * Rewrote parts of Silc Channel Payload interface in the
2363 lib/silccore/silcchannel.[ch]. The encode function now also
2364 encrypts the packet and parse function decrypts it.
2366 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2368 * Fixed a minor formatting bug in the SKE's key material processing.
2369 It actually might have processed the keys wrong way resulting
2372 * Redefined the mandatory HMAC algorithms and added new algorithms.
2373 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2374 and hmac-md5 truncated to 96 bits. The mandatory is now
2375 hmac-sha1-96. Rest are optional (including the one that used
2376 to be mandatory). Rationale for this is that the truncated HMAC
2377 length is sufficient from security point of view and can actually
2378 make the attack against the HMAC harder. Also, the truncated
2379 HMAC causes less overhead to the packets. See the RFC2104 for
2382 * Added new [hmac] configuration section. The SKE used to use
2383 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2384 is of course wrong. The official names that must be proposed in
2385 the SKE are the ones defined in the protocol specification
2386 (hmac-sha1-96 for example). The user can configure any hmac
2387 using any hash function configured in the [hash] section. At
2388 least, the mandatory must be configured.
2390 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2392 * Added HMAC list to the SKE proposal list. It has now both
2393 hash algorithm list and HMAC list. This makes the protocol
2394 incompatible with previous versions. The SKE now seems to work
2395 the way it is supposed to work, for the first time actually.
2397 * Defined plain Hash algorithms to the protocol specification.
2400 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2402 * Implemented support for key agreement packets into the server.
2403 Added functions silc_server_key_agreement and
2404 silc_server_send_key_agreement. Other than these functions,
2405 server has nothing to do with this packet.
2407 * Added support for private message key packets into the server.
2408 Added functions silc_server_private_message_key and
2409 silc_server_send_private_message_key.
2413 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2414 called in the protocol's final callback instead in the END
2415 protocol state. This makes a little more sense and in the same
2416 time in client we can use the same protocol routines for normal
2417 key exchange and to key agreement packet handling as well.
2419 * Added to both client's and server's KE protocol context the
2420 SilcSKEKeyMaterial pointer to save the key material. We will
2421 bring the key material to the protocol's final callback by doing
2422 this. The final callback must free the key material.
2424 * Added SKE's packet_send callback into client's KE protocol
2425 context so that the caller can choose what packet sending function
2426 is used. This way we can use different packet sending when
2427 doing normal SKE when doing key agreement packet handling (in
2428 the key agreement packet handling we do not want to encrypt
2431 * Implemented the responder side of the key agreement routines
2432 in the client. The client can now bind to specified port and
2433 accept incoming key negotiation. The key material is passed
2434 to the application after the protocol is over.
2436 * Implemented the processing of incoming Key Agreement packet
2437 in the client. Added function silc_client_key_agreement to
2440 * Implemented the intiator side of the key agreement routines
2441 in the client. The client can now initiate key agreement with
2442 another remote client. The key material is passed to the
2443 application after the protocol is over.
2445 * Created client_keyagr.c to include all the key agreement
2448 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2449 SILC_TASK_CALLBACK except that it is not static.
2451 * Created client_notify.c and moved the Notify packet handling
2452 from the client.[ch] into that file.
2454 * Created client_prvmsg.c and moved all private message and
2455 private message key routines from the client.[ch] into that file.
2457 * Create client_channel.c and moved all channel message and
2458 channel private key routines from the client.[ch] into that file.
2460 * Changed silc_client_get_client_by_id_resolve to resolve with
2461 WHOIS command instead of IDENTIFY command, in the file
2462 lib/silclient/idlist.c.
2464 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Implemented the SKE's responder side to the Client library.
2468 * When FAILURE is received to the protocol do not trust it
2469 blindly. Register a timeout to wait whether the remote closes
2470 the connection as it should do it, only after that process the
2471 actual failure. This was changed to both client and server.
2473 * Added client_internal.h to include some of the structures
2474 there instead of client.h in lib/silcclient/.
2476 * Added function silc_task_unregister_by_callback to unregister
2477 timeouts by the callback function.
2479 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * Some "Incomplete WHOIS info" errors has been appearing on the
2482 log files. Took away the entry->userinfo check from WHOIS
2483 reply sending. The entry->userinfo is now " " if client did not
2484 provide one. I thought this was fixed earlier but something
2485 is wrong still. Let's see if the error still appears.
2487 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2489 * Fixed a minor bug in the login when the channel key is
2490 re-generated in the server. It used to generate the key in
2491 wrong order and thus caused problems in the channel traffic.
2493 * Fixed a minor bug in channel key distsribution after
2494 KICK command. The key was not sent to the router even though
2497 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2499 * Added silc_ske_process_key_material_data as generic routine
2500 to process any key material as the SILC protocol dictates. The
2501 function is used by the actual SKE library but can be used by
2502 applications as well. This relates to the private message keys
2503 and the channel private keys since they must be processed the
2504 same way the normal SILC session keys. The protocol dictates
2505 this. Affected files: lib/silcske/silcske.[ch].
2507 Added also silc_ske_free_key_material to free the
2508 SilcSKEKeyMaterial structure.
2510 * Defined silc_cipher_set_key function to set the key for
2511 cipher without using the object's method function. The affected
2512 files: lib/silccrypt/silccipher.[ch].
2514 * Implemented silc silc_client_add_private_message_key,
2515 silc_client_add_private_message_key_ske,
2516 silc_client_del_private_message_key,
2517 silc_client_list_private_message_keys and
2518 silc_client_free_private_message_keys functions in the
2521 Added functions silc_client_send_private_message_key to send
2522 the Private Message Key payload and silc_client_private_message_key
2523 to handle incoming Private Message Key payload.
2525 * Added Cipher field to the Private Message Key payload to set
2526 the cipher to be used. If ignored, the default cipher defined
2527 in the SILC protocol (aes-256-cbc) is used.
2529 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2531 * Removed lib/silcclient/ops.h file.
2533 Redefined parts of the SILC Client Library API. Created new
2534 file silcapi.h that deprecates the ops.h file and defines the
2535 published Client Library API. Defined also private message key
2536 API and channel private key API into the file.
2538 This is the file that the application must include from the
2539 SILC Client Library. Other files need not be included by
2540 the application anymore.
2542 * Added new key_agreement client operation callback and also
2543 defined the Key Agreement library API for the application.
2545 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2547 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2548 is used by clients to request key negotiation between another
2549 client in the SILC network. If the negotiation is started it
2550 is performed using the SKE protocol. The result of the
2551 negotiation, the secret key material, can be used for example
2552 as private message key.
2554 Implemented the Key Agreement payload into the files
2555 lib/silccore/silauth.[ch].
2557 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2559 * Redefined ciphers for the SILC protocol. Added some new ciphers
2560 and defined the key lengths for the algorithms. Changed the
2561 code accordingly. The default key length is now 256 bits.
2563 * Fixed SKE key distribution function silc_ske_process_key_material
2564 when the key length is more than 128 bits. The default key
2565 length in SILC is now 256 bits.
2567 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2568 to indicate unsupported algorithm.
2570 * Renamed rijndael.c to aes.c and all functions as well.
2572 * Fixed a long standing channel key setting bug in client library.
2573 Weird that it has never surfaced before.
2575 * Fixed bug in channel deletion. If the entire channel is removed
2576 then it must also delete the references of the channel entry
2577 from the client's channel list as the client's channel entry and
2578 the channel's client entry share same memory.
2580 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2582 * Implemented CONNECT and SHUTDOWN commands in the client.
2584 * Implemented CLOSE command to the client.
2586 * Added the function silc_idlist_find_server_by_name into the
2587 files silcd/idlist.[ch].
2589 Added the function silc_idlist_find_server_by_conn into the
2590 files silcd/idlist.[ch].
2592 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * DIE command was renamed to SHUTDOWN. Updated the both code
2597 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2598 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2600 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2603 * Added function silc_server_create_connection function to create
2604 connection to remote router. My server implementation actually
2605 does not allow router to connect to normal server (it expects
2606 that normal server always initiates the connection to the router)
2607 so the CONNECT command is only good for connecting to another
2610 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2613 or some other client was kicked from the channel.
2615 Implemented the handling of the notify type to both client
2618 Implemented silc_server_send_notify_kicked to send the KICKED
2619 notify. It is used to send it to the server's primary router.
2621 * Implemented the KICK command into server and client.
2623 * Added `query' argument to the silc_idlist_get_client function
2624 to indicate whether to query the client from server or not if
2627 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2628 to indicate that the client is not channel founder.
2632 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * Removed the rng context from SilcPacketContext structure and
2635 changed that the packet routine uses the Global RNG API.
2637 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Added support for quit message that client can "leave" on the
2640 channel when it quits the SILC. It is ditributed inside the
2641 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2643 Added silc_server_free_client_data that will take the
2644 signoff message as argument.
2646 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2648 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2650 * Updated parts of the protocol specification to keep it up
2653 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2656 payloads in one packet.
2658 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2659 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2660 use now the new List flag.
2662 * Also deprecated the following packet types: REPLACE_ID,
2663 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2665 * Added list support for Notify packet in server.
2667 * Added silc_server_send_notify_channel_change to send the
2668 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2669 the silc_server_send_replace_id.
2671 * Added silc_server_send_notify_nick_change to send the
2672 NICK_CHANGE notify type. Deprecates the function
2673 silc_server_send_replace_id.
2675 * Added silc_server_send_notify_join to send the JOIN notify type.
2676 Deprecates the function silc_server_send_new_channel_user.
2678 * Added silc_server_send_notify_leave to send LEAVE notify type.
2679 Deprecates the function silc_server_send_remove_channel_user.
2681 * Added silc_server_send_notify_cmode and
2682 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2683 types. Deprecates the silc_server_send_set_mode function.
2685 * Added SERVER_SIGNOFF notify type to indicate that server has
2686 quit. This means that all clients on the channel from that
2687 server will drop. This can be also used when netsplit happens.
2689 Deprecated REMOVE_ID packet type since it is not needed anymore
2692 Added silc_server_send_notify_server_signoff to send the
2693 SERVER_SIGNOFF notify type. Deprecates the function
2694 silc_server_send_remove_id.
2696 Added also silc_server_send_notify_signoff to send the
2697 SIGNOFF notify type.
2699 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2700 SILC protocol from this day on. Changed the protocol
2701 specification as well.
2703 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2704 notify type. It is used between routers to notify about
2705 topic changes on a channel.
2707 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2710 * Partly updated the protocol specification to comply with the
2711 changes now made. It is still though a bit outdated.
2713 * The JOIN notify type now takes one extra argument <Channel ID>.
2714 The packet used to be destined to the channel but now the
2715 JOIN type may be sent as list thus it is impossible to
2716 destine it to any specific channel. By adding this argument
2717 it is again possible.
2719 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Added CREDITS file. The CHANGES and CREDITS file will appear
2722 in the distribution as well.
2724 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2726 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2727 types in the server's silcd/packet_receive.c.
2729 * Implemented CMODE and CUMODE to work in router environment.
2731 * Fixed minor encoding and decoding buglet from the
2732 lib/silccore/silcmode.c.
2734 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2737 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2739 * Changed all SilcConfigServer* and silc_config_server* to
2740 SilcServerConfig* and silc_server_config*, respectively.
2743 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Associated the ID (client or server ID) to the Authentication
2746 Payload to avoid any possibility of forging. Updated the
2747 protocol specification and the code accordingly.
2749 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2751 * The RSA key length is now save to the RsaKey context in the
2752 key generation process in lib/silccrypt/rsa.c. The key length
2753 is now used to figure out the maximum size of the block allowed
2754 to be encrypted/signed.
2756 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2757 is equivalent to the silc_mp_mp2bin but does not allocate any
2760 * Changed silc_mp_mp2bin API to take length argument. If it is
2761 non-zero then the buffer is allocated that large. If zero, then
2762 the size is approximated using silc_mp_sizeinbase, which however
2765 * Created Global RNG API which is global RNG that application can
2766 initialize. After initializing, any routine anywhere in the
2767 code (including library) can use RNG without allocating a new
2768 RNG object. This was done to allow this sort of use of the
2769 RNG in code that has no chance to allocate RNG object. All
2770 applications currently allocate this and many routines in the
2771 library use this. Affected file lib/silccrypt/silcrng.[ch].
2773 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2774 it to use the Global RNG API.
2776 * Defined Authentication Payload into protocol specification that
2777 is used during SILC session to authenticate entities. It is
2778 used for example by client to authenticate itself to the server
2779 to obtain server operator privileges.
2781 Implemented this payload into the lib/silccore/silcauth.[ch].
2782 Implemented also routines for public key based authentication
2783 as the new protocol specification dictates.
2785 Moved definitions of different authentication methods from
2786 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2788 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2789 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2790 silc_pkcs_verify_with_hash functions into the file
2791 lib/silccrypt/silcpkcs.[ch].
2793 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2795 * The client entry's userinfo pointer must be always valid.
2796 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2797 will fail since it requires the userinfo. Now, the userinfo
2798 is allocated as "" if actual userinfo does not exist. Actually,
2799 it must exist and it is totally Ok to drop client connections
2800 that does not announce the userinfo. However, we will make
2801 this workaround for now.
2803 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2804 to return the remote port by socket.
2806 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2808 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2809 SILC_SERVER_PENDING_EXEC and added an new macro
2810 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2811 data or when error occurs while processing the pending command.
2813 Added new argument `destructor' into silc_server_command_pending
2814 and to the SilcServerCommandPending object. This destructor is
2815 now called after calling the pending callback or if error occurs
2816 immediately. If error occurs the actual pending callback won't
2817 be called at all - only the destructor. The destructor may be
2818 NULL if destructor is not needed.
2820 All this applies for client library code as well. Similar
2821 changes were made there as well for the pending commands.
2823 In the client, the application must now allocate the
2824 SilcClientCommandContext with the silc_client_command_alloc
2827 * Added reference counter to the SilcServerCommandContext. Added
2828 function silc_server_command_alloc and silc_server_command_dup
2831 Same type of functions added to the client library for the same
2834 * Removed the cmd_ident from IDListData away since it is now
2835 global for all connections. It is the command identifier used
2836 in command sending and with pending commands. The affected file
2839 * Added reference counter to the SilcSocketConnection objecet to
2840 indicate the usage count of the object. The object won't be
2841 freed untill the reference counter hits zero. Currently only
2842 server uses this, and client ignores it. The client must be
2843 set to use this too later. The affected files are
2844 lib/silccore/silcsockconn.[ch]. Added also the function
2845 silc_socket_dup to increase the reference counter.
2847 This was mainly added because it is possible that the socket
2848 is removed underneath of pending command or other async
2849 operation. Now it won't be free'd and proper DISCONNECTING
2850 flags, etc. can be set to avoid sending data to connection that
2851 is not valid anymore.
2853 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2854 the connection. After that it sets SILC_SET_DISCONNECTED.
2855 It is, however, possible that the socket data is not still freed.
2856 The silc_server_packet_process now checks that data is not
2857 read or written to connection that is DISCONNECTED. The socket
2858 get's freed when the reference counter hits zero.
2860 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2862 * Changed the client operation API: channel_message operation's
2863 `sender' is now the client entry of the sender, not the nickname
2864 and the `channel' is the channel entry, not the channel name.
2866 In the private_message operation the `sender' is now also the
2867 client entry of the sender not the nickname.
2869 Affected file is lib/silcclient/ops.h and all applications
2870 using the client operations.
2872 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Moved the calling of ops->connect() from connect_to_server_final
2875 into receive_new_id functin since that is the point when the
2876 client is actually allowed to send traffic to network. The
2877 affected file is lib/silcclient/client.c.
2879 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2882 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2883 (if needs broadcasting) instead of broadcasting the packets one
2884 by one which would make a burst in the network traffic.
2886 * Added `broadcast' argument to the functions in silcd/server.[ch]
2887 silc_server_create_new_channel[_with_id] to indicate whether
2888 to send New Channel packet to primary router.
2890 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Added new function into the silcd/server.[ch] files:
2893 silc_server_create_new_channel_with_id to create new channel with
2894 already existing Channel ID.
2896 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2897 lib/silccore/silcpacket.h. This packet is used t send list of
2898 Set Mode payloads inside one packet. Server uses this to set
2899 the modes for the channels and clients on those channels, that it
2900 announced to the router when it connected to it. The protocol
2901 specification has been updated accordingly.
2903 * The silc_server_new_channel did not handle the packet coming
2904 from normal server as it normally does not send that. However,
2905 when it announces its channels it does send it. Implemented
2906 the support for that.
2908 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2909 into the file lib/silccore/id.h.
2911 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2913 * Fixed memory leaks in the functions silc_idlist_del_client,
2914 silc_idlist_del_channel and silc_idlist_del_server in the file
2915 silcd/idlist.c. All of those leaked like a sieve.
2917 * Fixed some small memory leaks in the client's function
2918 silc_client_notify_by_server.
2920 * Added functions into silcd/server.c: silc_server_announce_clients,
2921 silc_server_announce_channels and silc_server_announce_server.
2922 These functions are used by normal and router server to announce
2923 to its primary router about clients, channels and servers (when
2924 router) that we own. This is done after we've connected to the
2927 These functions effectively implements the following packet types:
2928 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2929 and SILC_PACKET_NEW_ID_LIST.
2931 * Added new functions into the silcd/packet_receive.[ch]:
2932 silc_server_new_id_list, silc_server_new_channel_list and
2933 silc_server_new_channel_user_list to handle the incoming
2934 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2936 * Added support of changing Channel ID in the function
2937 silc_server_replace_id. If the server that announces a channel
2938 to the router already exists in the router (with same name but
2939 with different Channel ID), router is responsible to send
2940 Replace ID packet to the server and force the server to change
2941 the Channel ID to the one router has.
2943 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2944 client that the Channel ID has been changed by the router. The
2945 normal server sends this to the client. Client must start using
2946 the new Channel ID as the channel's ID.
2948 Implemented handling of this new type into lib/silcclient/client.c
2949 into the function silc_client_notify_by_server.
2951 * Added new function silc_idlist_replace_channel_id into the files
2952 silcd/idlist.[ch] to replace the Channel ID.
2954 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2956 * Call silc_server_command_identify_check always when processing
2957 the IDENTIFY command in silcd/command.c
2959 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2961 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2962 send keepalive packets. The packet can be sent by clients,
2963 servers and routers.
2965 Added function silc_socket_set_heartbeat into the file
2966 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2967 If not set, the heartbeat is not performed. The actual
2968 heartbeat is implemented in the low level socket connection
2969 library. However, application is responsible of actually
2972 Added silc_server_send_heartbeat to send the actual heartbeat
2973 packet into silcd/packet_send.[ch]. Server now performs
2974 keepalive with all connections.
2976 * Added silc_task_get_first function into lib/silcutil/silctask.c
2977 to return the timeout task with shortest timeout. There was a bug
2978 in task unregistration that caused problems. TODO has been
2979 updated to include that task system must be rewritten.
2981 * The client library will now resolve the client information when
2982 receiving JOIN notify from server for client that we know but
2983 have incomplete information.
2985 * Rewrote parts of silc_server_remove_from_channels and
2986 silc_server_remove_from_one_channel as they did not remove the
2987 channel in some circumstances even though they should've.
2989 * Encryption problem encountered in server:
2991 The LEAVE command used to send the Channel Key packet to the
2992 router immediately after generating it. However, the code
2993 had earlier sent Remove Channel user packet but not immediately,
2994 ie. it was put to queue. The order of packets in the router
2995 was that Channel Key packet was first and Remove Channel User
2996 packet was second, even though they were encrypted in the
2997 reverse order. For this reason, MAC check failed. Now, this
2998 is fixed by not sending the Channel Key packet immediately but
2999 putting it to queue. However, this is more fundamental problem:
3000 packets that are in queue should actually not be encrypted
3001 because packets that are sent immediately gets encrypted
3002 actually with wrong IV (and thus MAC check fails). So, packets
3003 that are in queue should be encrypted when they are sent to
3004 the wire and not when they put to the queue.
3006 However, the problem is that the current system has not been
3007 designed to work that way. Instead, the packet is encrypted
3008 as soon as possible and left to the queue. The queue is then
3009 just purged into wire. There won't be any fixes for this
3010 any time soon. So, the current semantic for packet sending
3013 o If you send packet to remote host and do not force the send
3014 (the packet will be in queue) then all subsequent packets to the
3015 same remote host must also be put to the queue. Only after the
3016 queue has been purged is it safe again to force the packet
3019 o If you send all packets immediately then it safe to send
3020 any of subsequent packets through the queue, however, after
3021 the first packet is put to queue then any subsequent packets
3022 must also be put to the queue.
3024 Follow these rules and everything works fine.
3026 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3028 * Added new function silc_server_remove_clients_by_server to
3029 remove all client entries from ID list when the server connection
3030 is lost. In this case it is also important to invalidate all
3031 client entires as they hold the invalid server entry. This
3032 fixes fatal bug when server has lost connection and will reconnect
3035 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3037 * Made some sanity checks to silc_server_daemonise like to check
3038 whether the requested user and group actually exists.
3040 * Added sanity check to SKE's silc_ske_responder_finish to check
3041 that the public and private key actually is valid.
3043 * Invalidate the client's nickname when receiving Replace ID
3044 packet and the Client ID is being replaced. This means that the
3045 server will query the nickname if someone needs it (client)
3048 * Sort the ID Cache in client library when the ID Cache data
3049 has changed (needs sorting).
3051 * Do not allow for SILC client to create several connections to
3052 several servers. The client does not support windows right now
3053 and generating multiple connections causes weird behaviour.
3055 Irssi-silc client does support windows and can handle several
3056 connections without problems, see: www.irssi.org and SILC plugin.
3058 * Fixed some places where client was added to the IDList. The
3059 rule of thumb is following (in order to get everything right):
3060 If the client is directly connected local client then the
3061 `connection' argument must be set and `router' argument must be
3062 NULL to silc_idlist_add_client function. If the client is not
3063 directly connected client then the `router' argument must
3064 bet set and the `connection' argument must be NULL to the
3065 silc_idlist_add_client function.
3067 * The funtion silc_server_packet_send_local_channel actually did
3068 not check whether the client was locally connected or not. It
3069 does that now. Fixed a bug related to LEAVE command.
3071 * Fixed Remove Channel User payload parsing bug in server's
3072 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3074 * The server's silc_server_save_channel_key now checks also the
3075 global ID list for the channel as it might not be in the local
3076 list. Fixed a bug related to LEAVE command.
3078 * Is this the end of the [<unknown>] buglet that has been lurking
3079 around for a long time? A little for loop fix in server's
3080 silc_server_command_whois_parse that is used by both IDENTIFY
3081 and WHOIS command. At least, this was a clear bug and a cause
3082 of one type of [<unknown>] buglet.
3084 * WHOIS and IDENTIFY commands call the function
3085 silc_server_command_[whois/identify]_check function even if
3086 we are not router server.
3088 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * Added --with-gmp configuration option. If set the GMP
3091 is always compiled in the SILC source tree. If not set then
3092 it is checked whether the system has the GMP3 installed. If
3093 it has then the GMP won't be compiled (the system's headers
3094 and library is used), if it doesn't have it then the GMP is
3095 compiled in the SILC source tree.
3097 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3099 * Changed RSA private exponent generation to what PKCS #1
3100 suggests. We try to find the smallest possible d by doing
3101 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3102 not security fix but optimization.
3104 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3106 * Added new config entry [Identity] to fork the server and run
3107 it as specific user and group. A patch from Bostik.
3109 * Imported Dotconf configuration library into lib/dotconf.
3110 This will be used to create the SILC configuration files later.
3111 It will appear in the distsribution after this commit.
3113 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * A big code auditing weekend happening. Auditing code for
3116 obvious mistakes, bugs and errors. Also, removing any code
3119 Removed files for being obsolete:
3121 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3122 inline in the file lib/silcutil/silcbuffer.h)
3124 o lib/silcutil/silcbufutil.c (the header has inline versions)
3126 Changed code to fix possible error conditions:
3128 o The buffer formatting routines now check that the destination
3129 buffer really has enough space to add the data. This applies for
3130 both buffer formatting and unformatting
3131 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3132 unformatting was changed to accomodate following rules:
3133 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3134 sent to the function while XXX_*STRING will not allocate or copy
3135 the data into the buffer. Instead it sets the pointer from the
3136 buffer into the pointer sent as argument (XXX_*STRING used to
3137 require that the pointer must be allocated already). This change
3138 makes this whole thing a bit more consistent and more optimized
3139 (note that the data returned in the unformatting with XXX_*STRING
3140 must not be freed now). The routines return now -1 on error.
3142 o Tried to find all code that use buffer_format and buffer_unformat
3143 and added return value checking to prevent formatting and
3144 especially unformatting errors and possible subsequent fatal
3147 o Changed ske->x and ske->KEY to mallocated pointers in
3148 lib/silcske/silcske.h. Fixed possible data and memory leak.
3150 o Added return value checking to all *_parse* functions. Fixed
3151 many memory leaks as well.
3153 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3154 so that buffer overflows would not happen. All code now also
3155 checks the return value as it can fail.
3157 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3159 * Added reconnection support to server if the normal server looses
3160 its connection to the router (for example if router is rebooted).
3161 The server performs normal reconnection strategy implemented
3162 to the server. Affected file silcd/server.c.
3164 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Added new packet type SILC_PACKET_SET_MODE that is used to
3167 distribute the information about changed modes (for clients,
3168 channels and clients channel modes) to all routers in the
3169 network. Updated the protocol specification accordingly.
3171 Added functions into silcd/packet_send.c and
3172 silcd/packet_receive.c: silc_server_send_set_mode,
3173 silc_server_set_mode.
3175 Added new files silcmode.[ch] into lib/silccore that implements
3176 the encoding and decoding of Set Mode Payload. Added new type
3177 SilcSetModePayload. Moved the definitions of different modes
3178 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3180 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Oops, a little mistake in server's connection authentication
3183 protocol. The protocol is not ended with FAILURE but with
3184 SUCCESS if the authentication is Ok. :) Affected file is
3187 * Implemented NICK_CHANGE notify handling in server in the file
3188 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3189 the local clients on the channel. After the changing nickname
3190 in router environment snhould work and the [<unknown>] nickname
3191 should appear no more.
3193 The silc_server_replace_id function that receives the Replace ID
3194 payload now sends the NICK_CHANGE notify type also in the file
3195 silcd/packet_receive.c
3197 * Changed WHOIS and IDENTIFY command to support the maximum amount
3198 of arguments defined in protocol specs (3328 arguments). This
3199 fixed a bug that caused problems when there were more than three
3202 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3204 * Added extra parameter, command identifier, to the
3205 silc_client_send_command so that explicit command identifier
3208 Changed that ID list routines uses specific command identifier
3209 when sending WHOIS/IDENTIFY requests to the server so that they
3210 can be identified when the reply comes back.
3212 Affected files lib/silcclient/command.[ch],
3213 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3215 * Added `sender' argument to silc_server_packet_send_to_channel
3216 to indicaet the sender who originally sent the packet to us
3217 that we are now re-sending. Ignored if NULL. Affected file
3218 silcd/packet_send.[ch].
3220 * Added some server statistics support in silcd/server_internal.h
3221 SilcServerStatistics structure and around the server code. Also
3222 send some nice statistics information when client is connecting
3225 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Fixed channel ID decoding in server's JOIN command reply in
3228 silcd/command_reply.c
3230 * Fixed braodcasting of replace ID payload to not to send it if
3231 we are standalone server in silcd/packet_receive.c.
3233 * Fixed all channel message sending routines to not to send
3234 packets to clients that has router set, since they are routed
3235 separately in the same function earlier. Affects file
3236 silcd/packet_send.c and all channel packet sending functions.
3238 * In USERS reply, res_argv[i] are not allocated, the table
3239 is allocated. Thus changed that free the table, not its
3242 * In server's whois_check and identify_check if the client is
3243 locally connected do not send any WHOIS commands - they are not
3246 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3248 * Fixed some minor bugs in client when sending WHOIS command. The
3249 arguments was in wrong order.
3251 * Removed statis function add_to_channel from server in
3252 silcd/command.c that was previously used with the joining but
3255 * Tested USERS command in router environment successfully with two
3256 routers, two servers and two clients.
3258 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Reorganized the USERS command and command reply in client library
3261 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3262 When the command is given by user we register a pending command
3263 callback that will reprocess the command after the reply has been
3264 received from the server. When reprocessing the packet we then
3265 display the information. Thus, the USERS information is displayed
3266 now in the command callback instead of in the command reply
3267 callback. The processing of the command is same as previously
3268 when server has sent the command reply in the JOINing process.
3270 * Added to USERS command in silcd/command_reply.c to join the client,
3271 we didn't use to know about, to the channel after we've created
3272 a client entry for it. Also, for clienet we did know already still
3273 check whether it is on the channel or not and add it if not.
3275 * Removed silc_server_command_join_notify as the function and its
3278 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Changed the client's pending command handling to the same as the
3281 server's pending command handling. It is also now possible to
3282 execute command reply functions from other command reply
3283 function as the function callbacks for commands and command
3284 replies are one and same. The pending commands are not static
3285 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3286 in client connection context. Thus, pending commands are server
3287 connection specific as it is convenient.
3289 Changed the function silc_client_command_pending and
3290 silc_client_command_pending_del and added new function
3291 silc_client_command_pending_check. Removed the
3292 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3295 * Added cmd_ident, current command identifier, to the client
3296 connection context in lib/silcclient/client.h to keep track on
3297 command identifiers used in command sending. Client's command reply
3298 function handling now supports the mandatory command identifiers.
3300 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3301 funtions in client to fully support pending command callbacks.
3303 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3304 as one of the arguments to the application in the command reply
3307 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3308 before first releasing SILC but came back. Now it is removed again
3309 and should come back nomore. The FORWARDED flag was used only
3310 by the JOINing procedure by forwarding the command packet to router.
3311 Now, the JOINing procedure has been changed to more generic (due
3312 to various router environment issues) and FORWARDED is not needed
3313 anymore for anything. The protocol specification is yet to be
3316 Now, removed silc_server_packet_forward from server and the flag
3317 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3319 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3321 * Renamed NAMES command to USERS command. The NAMES was named that
3322 due to historical reasons. Now it is renamed. Also, rewrote
3323 parts of the USERS command. The nickname list is not sent anymore
3324 by the server. Only Client ID and mode lists are sent in the USERS
3325 command. Changed this also to the protocol specification.
3327 The client now resolves the names and stuff after it receives
3328 the USERS list from the server when joining to the channel.
3330 * WHOIS and IDENTIFY commands has been changed to support multiple
3331 Client ID's per command. One can now search for multiple users
3332 in the network by sending only one WHOIS or IDENTIFY command.
3333 Changed the code and the protocol specifications.
3335 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3336 uses silc_server_command_whois_parse to parse the request. */
3338 * If normal server, do not parse the WHOIS and IDENTIFY requests
3339 before sending it to the router. Saves some time.
3341 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3343 * Fixed JOIN command on client library. Wrong number of arguments
3344 used to crash the client.
3346 * Added silc_server_channel_has_global function to check whether
3347 channel has global users or not.
3349 * Added silc_server_channel_has_local function to check whether channel
3350 has locally connected clients on the channel.
3352 * The silc_server_remove_from_one_channel now checks whether the
3353 channel has global users or not after given client was removed from
3354 the channel. It also checks whether the channel has local clients
3355 on the channel anymore. If it does not have then the channel entry
3356 is removed as it is not needed anymore.
3358 * The silc_server_notify now checks on JOIN notify whether the joining
3359 client is one of locally connected or global. If it is global then
3360 the channel has now global users on the channel and that is marked
3361 to the channel entry. Also, it now saves the global client to
3362 global list who is joining and JOINs it to the channel. This is
3363 for normal server, that is.
3365 Changed silc_server_send_notify_on_channel,
3366 silc_server_packet_relay_to_channel and
3367 silc_server_packet_send_to_channel check if we are normal server
3368 and client has router set (ie. global client) do not send the
3369 message to that client, as it is already routed to our router.
3371 * Implemented LEAVE notify type handling in silc_server_notify
3374 * Tested LEAVE command in router environment successfully. Tested
3375 with two routers, two servers and two clients.
3379 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3381 * Implemented SIGNOFF notify type handling in silc_server_notify
3384 * silc_server_remove_id now removes the client entry from all channels
3385 it has joined and thusly sends SIGNOFF notify type.
3387 * Rewrote the NAMES list generation in server by removing two excess
3388 loops. The lists are created now inside one loop.
3390 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3392 * silc_server_remove_channel_user checks now also global list
3393 for channel and client.
3395 * silc_server_new_channel_user checks now both local and global
3396 list for channel and client. Fixed a bug in client id decoding.
3397 Used to decode wrong buffer.
3399 * silc_server_channel_message checks now both local and global
3400 list for channel entry.
3402 * Tested channel joining (hence JOIN) in router environment
3403 successfully. Tested with two routers, two servers and two
3406 * Tested channel message sending in router environment successfully.
3408 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Added silc_server_save_channel_key into server.[ch] to save the
3411 received channel key in Channel Key payload processing. It is
3412 also used in JOIN command reply handling.
3414 Equivalent function silc_client_save_channel_key added into
3415 client.[ch] into client library.
3417 * Changed JOIN command reply to send information whether the channel
3418 was created or not (is existing already) and the channel key
3419 payload. Changed protocol specs accordingly.
3421 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3422 the request was sent by ID and not by nickname. Crashed on
3425 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3428 now correctly save the received data.
3430 * silc_server_free_sock_user_data now notifies routers in the
3431 network about entities leaving the network.
3433 At the same time implemented functions silc_server_remove_id
3434 and silc_server_send_remove_id to receive and send REMOVE_ID
3435 packets. The packet is used to notify routers in the network
3436 about leaving entities. The ID removed will become invalid in
3439 * Added function silc_idlist_del_server into server. Removes and
3440 free's server entry from ID list.
3442 * silc_server_private_message function now checks, if we are router,
3443 that the destination ID really is valid ID, naturally.
3445 * In router when NEW_ID packet is received (for new client) the
3446 hash of the Client ID is saved in the ID Cache but the
3447 client->nickname is set to NULL, instead of putting the hash
3450 IDENTIFY command now also checks that client->nickname must be
3451 valid. If it is not if will request the data from the server who
3452 owns the client. Added new function
3453 silc_server_command_identify_check.
3455 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3456 to set the command to already allocated Command Payload.
3458 * Tested private message sending in router environment with two
3459 routers, two servers and two clients. Fixed minor bugs and now
3462 * Fixed segfault from client's NAMES command. Used to crash if
3465 * Forwarded packets must not be routed even if it is not destined
3466 to the receiver. Changed server code comply with this.
3468 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Added `require_reverse_mapping' boolean value to ServerParams
3471 structure. If TRUE (not default) the server will require that
3472 the connecting host has fully qualified domain name.
3474 If the reverse mapping is not required and hostname could not be
3475 found the IP address is used as hostname.
3477 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Implemented version string checking to both client and server.
3480 The check is incomplete currently due to the abnormal version
3481 strings used in development version of SILC.
3483 * Changed all command functions in server to use the new
3486 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3488 * Changed char *data to unsigned char *data in ID Cache system to
3489 support binary data as ID Cache data. Changed code to support
3490 binary data in lib/silccore/idcache.c.
3492 * Renamed silc_server_packet_relay_command_reply to
3493 silc_server_command_reply as it is normal packet receiving
3494 function. Rewrote the function to accept command replys for
3495 servers and not only for clients.
3497 * Mark remote router always as registered server if we are connecting
3498 to it. Otherwise, commands sent by the router to us are ignored.
3500 * All ID List find routines now returns the ID Cache Entry pointer
3501 as well if requested.
3503 * WHOIS command works now in router environment, tested with two
3504 routers, two servers and two clients.
3506 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3507 in router environment (as it is almost equivalent to WHOIS) but
3508 hasn't been tested thoroughly. Added new functions:
3510 silc_server_command_identify_parse
3511 silc_server_command_identify_send_reply
3512 silc_server_command_identify_from_client
3513 silc_server_command_identify_from_server
3515 * Disabled route cache adding because adding two different ID's with
3516 same IP replaces the old cache entry thus giving wrong route.
3517 The entry->router->connection is always the fastest route anyway
3518 so route cache may not be needed. Of course, new routes maybe
3519 established after receiving the ID when the entry->router->connection
3520 might not be anymore the most optimal.
3522 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Add route cache for received ID for fast routing.
3526 * Added silc_server_packet_route to route received packet on router
3527 that is not destined to us.
3529 * Renamed silc_server_get_route to silc_server_route_get.
3531 * Added id_string and id_string_len fields into SilcServer to
3532 include encoded ServerID for fast comparing without excess
3533 encoding of the ID's.
3535 * Cleaned up WHOIS command on server side. Added following static
3538 silc_server_command_whois_parse
3539 silc_server_command_whois_check
3540 silc_server_command_whois_send_reply
3541 silc_server_command_whois_from_client
3542 silc_server_command_whois_from_server
3544 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3545 arguments in command replies. All command functions should be
3546 updated to use this macro.
3548 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3550 * Minor typo fixes on command reply handling on server.
3552 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Added silc_server_command_add_to_channel internal routine to add
3555 the client to the channel after router has created the channel and
3556 sent command reply to the server.
3558 * Added generic silc_server_send_command to send any command from
3561 * Use static buffer with ID rendering instead of duplicating data.
3563 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3565 * Fixed a channel user mode bug when joining to a channel server gave
3566 everybody channel founder rights, oops.
3568 * We mark ourselves as the router of the incoming server connection
3569 if we are router ourselves. This way we can check in some packet
3570 sending functions whether it is locally connected server. For
3571 incoming router connections we put NULL.
3573 * For router sending packets locally means now always sending the
3574 packet cell wide; to local clients and local servers. For normal
3575 server sending packet locally means sending it to only local
3578 * Fixed the JOIN command to really work in router environment. If the
3579 channel is created it is always created by the router. Router is
3580 also responsible of making the initial joining to the channel,
3581 sending JOIN notify to the sending server and distributing
3582 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3583 does not exist server doesn't do anything else but forward the
3584 command to the router which performs everything.
3586 * Added silc_server_send_channel_key function to send the Channel Key
3589 * Added silc_server_create_channel_key to create new channel key. The
3590 channel key is now re-generated everytime someone joins or leaves
3591 a channel, as protocol dictates. Note: channel->key_len is the
3594 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3596 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3597 packet_receive.[ch] to separate packet sending and receiving
3598 routines. The server.[ch] now includes everything else including
3599 actual packet processing (writing and reading data) and other
3602 Renamed silc_server_private_message_send_internal to
3603 silc_server_send_private_message. The routine is still though
3604 used only to relay private messages as server does not send
3605 private messages itself.
3607 Renamed silc_server_new_channel to silc_server_create_new_channel
3608 and added new function sicl_server_new_channel that handles the
3609 incoming New Channel packet. Added also new sending function
3610 silc_server_send_new_channel to send New Channel Payload.
3612 * Added new function silc_server_notify to process incoming notify
3613 packet to the server/router. Server may then relay the notify
3614 to clients if needed.
3616 * Added new function silc_server_new_channel_user to process incoming
3617 New Channel User packet. Router will redistribute the packet and
3618 send JOIN notify to its local clients and locally connected servers
3619 if needed. Normal server will send JOIN notify to its local client
3620 on same channel when received this packet. Added also corresponding
3621 sending function silc_server_send_new_channel_user to sent the
3624 * Added boolean route argument to send_notif_to_channel and
3625 packet_send_to_channel functions to attempt to route the packet
3626 if it is TRUE and send only locally if it is FALSE.
3628 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * silc_server_replace_id now broadcasts the received replace ID
3631 packet if it is not broadcast packet already. The router must
3632 broadcast to inform other routers about changed ID.
3634 * Added backpointer to server's router into SilcServer context in
3635 silcd/server_internal.h.
3637 * Fixed silc_server_packet_broadcast to send correct broadcast
3640 * The channel key is now distributed to the local client as soon
3641 as it is received from the router (in router environment) so that
3642 no other packet may be sent for the channel until client has
3645 * silc_server_remove_channel_user now broadcasts the received
3646 Remove Channel User packet if it is not broadcast packet already.
3647 The router must broadcast to inform other routers about removed
3650 * Added users field into SilcPacketContext that is a reference count
3651 of the context. One can increase the reference count by calling
3652 silc_packet_context_dup which is now changed to just increase the
3653 reference count instead of duplicating the data. The reference
3654 count is decresed by calling silc_packet_context_free that will
3655 free the data after the reference count hits zero.
3657 For now on the packet context and everything allocated into it
3658 (including the raw packet from network) must be freed by calling
3659 the new silc_packet_context_free function. Added also new function
3660 silc_packet_context_alloc that must be used now to allocate the
3661 context. This also means that if a routine is asynchronous from
3662 silc_[client/server]_packet_parse_type the packet context must
3663 be duplicated by calling silc_packet_context_dup. Otherwise it
3664 gets free'd after silc_[client/server]_packet_parse_type returns.
3665 Also, one must remember that if packet is duplicated then its
3666 reference count must be decresed by calling the free function as
3667 many times as it was duplicated.
3669 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3670 from both client and server.
3672 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Made joining to a channel working in router environment.
3676 * Cleaned up JOIN command on server side and create function
3677 silc_server_command_join_channel internal routine to make the
3680 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Changed silc_command_pending list to SilcDList. Also, added
3683 `ident' field to SilcServerCommandPending structure to identify
3684 the reply and to call correct callback.
3686 Added silc_server_command_pending_check function to replace the
3687 corresnponding macro. The silc_command_pending list is not
3690 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3691 to set identifier to previously allocated Command Payload. It
3692 is used to set identifier for command when resending Command
3695 * Added silc_command_payload_encode_payload to encode Command
3696 Payload buffer from SilcCommandPayload structure.
3698 * Added silc_argument_payload_encode_payload to encode Argument
3699 payload buffer from SilcArgumentPayload structure.
3701 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3703 * Changed WHOIS command to support router connection on server side.
3704 The whois request is always sent to router unless the server is
3705 standalone server. After server has received the reply from the
3706 router will it send the reply to the client.
3708 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3709 broadcast received broadcast packet. The function is used only
3710 by router. The broadcast packet is always sent to the router's
3713 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3714 render given ID to printable string, for log files for example.
3716 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Made basic router to router connections working. At least they
3719 can now connect to each other but nothing really works the way
3720 they are supposed - yet.
3722 * Added new initiator token to RouterConnection configuration
3723 file in silcd/serverconfig.[ch]. It is used to tell whether we
3724 are the initiator to the remote router or whether we'll expect
3725 the other end to connect.
3727 * Moved registering of listener task to silc_server_init, hence
3728 the server starts listenning as soon as it is run, even if it
3729 does not have connections to other routers. Let's see how well
3732 * Changed default connection retry timeouts for more suitable in
3735 * Removed cipher and such arguments from silc_idlist_add_client
3736 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3737 Added new function silc_idlist_add_data to add the keys and stuff
3740 * Added SilcIDListData structure and added it to SilcClientEntry
3741 and SilcServerEntry as their first field in the structure. This
3742 way we can explicitly cast the ID entries to the SilcIDListData
3743 structure and get common data for the entries. In past, we had
3744 to first check what type of connection it is and then cast it to
3745 correct ID entry type. Now, we can directly cast the opaque
3746 pointer to the SilcIDListData (no matter what ID entry it actually
3747 is) and get the data needed.
3749 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3752 in some circumstances even if threre were timeout tasks, though not
3753 IO tasks, but tasks anyway. Now fixed.
3755 * Defined SilcServerConnection structure to hold connection specific
3756 stuff about directly connected servers and routers. The definition
3757 is currently in silcd/server_internal.h. I thought about having
3758 a bit more important role fro this struct but for now it is used
3759 only when connecting to other server (or router actually).
3761 * Added connecting retry support in server when connecting to
3762 router(s). The retry feature implement exponential backoff
3763 algorithm. Also, added SilcServerParams structure to hold default
3764 parameters for server. For now, it include these retry settings
3765 and are hard coded. After server is moded to be as Silc Server
3766 Library this structure will be more important.
3768 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Changed client librarys channel->clients table to SilcList and
3771 changed code accordingly.
3773 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Changed client's channel table to SilcList and changed code
3776 accordingly. Also changed SilcChannelClientEntry to include back-
3777 pointer to the channel so that client entry can use that structure
3778 as list as well and we have fast cross-reference to the channel.
3779 This change dramatically decreased the complexity of channel
3780 handling with client entry and vice versa (removed one extra
3781 loop when searching for channel entry from many functions).
3783 * Changed server->sim from table to SilcDList and changed code
3786 * NAMES command can now be used from user interface. It will show
3787 the user list on the channel, neatly.
3789 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3790 Code now saves realname of the user if it becomes available.
3792 * Renamed configure.in to configure.in.pre and made ./prepare
3793 script to automatically add correct version string to
3794 configure.in which it creates from configure.in.pre.
3796 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * NAMES command reply now shows users mode with the nickname when
3801 * Moved silc_client_ch[u]mode[_char] functions from
3802 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3803 place sucks, they are utility functions and should be in some
3806 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3808 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3811 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Added TRQ (efficient deque and list library) into lib/trq. This is
3816 a very good list library that is currently used in the SILC. Defined
3817 SilcList API over the library because I didn't like the API very
3818 much. See lib/trq/silclist.h for the API and examples of how to
3819 use the API. Fixed various places in the code to use the new
3820 SilcList API. The SilcList is meant for lists that has a structure
3821 already defined as a list. It is not suitable to add just some
3822 context to the list (in TRQ, the context is the list actually).
3824 So, I defined SilcDList that can be used for the purpose where
3825 predefined list structure does not exit. This can be used as
3826 such list. Now some context just can be added to the SilcDList.
3827 Currently this list is not used in the SILC just yet, though there
3828 are a lot places where this can replace dynamically allocated
3829 tables and I will fix these places, later, to use SilcDList.
3830 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3831 and use TRQ internally).
3833 Also fixed some annoying warning messages that the original TRQ
3834 code generated. Also minor changes to TRQ's Makefile.in.
3836 * Added support for querying by Client ID to both WHOIS and
3837 IDENTIFY commands into server, as required by the protocol.
3839 * Removed method function pointers from SilcBuffer structure. They
3840 weren't used to anything and just increased the context size for
3841 no good reason. This change also made silc_buffer_alloc and
3842 silc_buffer_free functions inline functions.
3844 * Disabled command flooding detection support until it's fixed so
3845 that it accepts commands in but does not execute them more than once
3848 * Added silc_net_localhost(), to return local hostname, into
3849 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3850 that must be initialized before calling silc_client_init.
3852 * Added new function: silc_server_send_notify_on_channels to send
3853 notify messages to all channels client has joined. It is assured
3854 that the message is sent only once per client.
3856 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3857 lib/silcutil/silcutil.[ch] as silc_format function. The new
3858 function is generic and is used by server as well, not only by
3859 the logging routines.
3861 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3862 the provided version string was not acceptable. Added new function:
3863 silc_ske_check_version into lib/silcske/silcske.h. The function
3864 must be implemented by the application (client or server) and it
3865 does not reside in the SKE library. The function checks the version
3866 string remote end sent.
3868 * Added back pointers (to opaque context and to SilcSocketConnection)
3869 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3871 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3872 duplicate packet context structure.
3874 * Changed `notify' client operation to send same arguments as client
3875 receives from server except for ID's. ID's are mapped to correct
3876 ID entry and that is returned. Also, if channel entry is not sent
3877 by server but the notify is for channel the channel entry is sent
3878 to application (otherwise application doesn't know that it is for
3879 channel (library gets it from packet's Destination ID)).
3881 * Added silc_client_remove_from_channels into client library to
3882 remove a client from all channels it has joined to. Used when
3883 received SIGNOFF notify from server. Added also new function
3884 silc_client_replace_from_channels to replace old ID entry with
3885 new ID entry on all channels. Used when received NICK_CHANGE
3888 * Fixed ID Cache list handling in silc_idlist_get_client in
3889 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3890 to get (or query) client by ID.
3892 * Updated TODO list.
3894 * Added connection authentication status message defined by the
3895 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3896 support for these into the code in client and server side.
3898 * Added generic function silc_client_send_command to send any command
3899 with variable argument list. Application should use this function
3900 to send commands if the command functions provided by the library
3901 does not suite for the application's user interface needs.
3903 * Added new `failure' client operation. Application is notified about
3904 received failure packet if client is executing a protocol. In this
3905 case the protocol's execution has failed.
3907 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3908 is required by the protocol.
3910 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3911 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3914 * Added status flag to SilcSKE object to indicate realtime status
3915 of the SKE protocol.
3917 * Application receives now exactly same command reply arguments as
3918 the library receives from server. However, if ID is received the
3919 corresponding ID entry is returned to the application (eg. Client
3920 ID is mapped to correct SilcClientEntry entry and that is returned).
3921 Changed command_reply client operation due to this change.
3923 * Changed all ID's in commands and in command replys as ID Payloads.
3924 Change affected both client and server side codes.
3926 All ID's sent in SILC network (with execption of ID's in SILC
3927 Packet header) are sent in ID Payload to support variable length
3930 * Server now notifies nick changes and notifies all clients on
3931 the channels about the new nickname (about the new Client ID,
3934 * Implemented CMODE command to change channel modes. Supports all
3935 channel modes defined by the protocol specs except ban and invite
3936 lists. (Also, private channel key mode is supported but support for
3937 setting private channel key in client is missing, thus, this mode
3938 has no effect on client side (except that server requires that the
3939 client uses private channel key and normal channel traffic does not
3942 Also, invite mode works per se, but INVITE command does not work
3943 yet correctly, so you can set channel as invite only channel but
3944 inviting clients to the channel does not work (it is yet to be
3945 thought what's the best way to do it).
3947 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3948 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3949 Implemented CUMODE command to change user's mode on the channel.
3950 Supports all modes defined by the protocol specs.
3952 * Added NAMES command reply to return users modes on the channel.
3954 * Removed unnecessary and slow ciphers from lib/silccrypt.
3956 * Set SO_KEEPALIVE option to connection sockets by default.
3958 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3960 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3961 redefined the Notify Payload into protocol specs.
3963 * Added silc_id_payload_parse_id to get ID directly from raw
3966 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3968 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3969 accept searching by Client ID as well.
3971 * Added support for LEAVE and SIGNOFF notify types in client library.
3973 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3974 to parse ID Payload from raw data.
3976 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3978 * Added flags parameter into silc_ske_assemble_security_properties
3979 function in lib/silcske/silcske.[ch].
3981 * Changed notify client operation to fit better for notify messages
3982 sent by server. The notify payload received from server is now
3983 passed to the application (after parsing it to SilcNotifyPayload).
3984 It is application's responsibility to retrieve the arguments
3985 from the payload and show the message the way it wants. The message
3986 sent by server is implementation specific.
3988 * Changed public keys to comply with the protocol specification.
3989 Old public keys are not supported anymore and are not compatible.
3991 * Removed nickname from Channel Payload as the latest draft removed
3992 it. The client must resolve the nickname from the NAMES command
3993 reply received when it joined the channel.
3995 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3997 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3999 * Fixed some errors in protocol specification drafts.
4001 * Created lib/silccore/silcnotify.c to implement Notify Payload
4002 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4003 generic payloads described by protocol specifications. The file
4004 includes implementations for ID Payload and Argument Payload.
4006 * Changed Command Payload implementation to use the new Argument
4007 Payload. Changed command_xxxx_payload to command_payload_xxxx
4008 to comply with SILC coding conventions.
4010 * Added suppport for Argument Payload handling in Notify Payload
4011 implementation as protocol requires it. Added the new support
4012 into server and client lib as well.
4014 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Added support for multiple nicknames on same channel. [n] is
4017 added locally to the nickname if there are more than one same
4018 nicknames on the channel.
4020 * Server now sends all nicknames that matched WHOIS request.
4021 Client also shows the list received from server.
4023 * Added TOPIC command to client side. User can now set and show
4024 current topic on channel.
4026 * Added MOTD command to client and server. Also, server sends the
4027 motd when client connects to the server.
4029 * Changed version strings to comply ISO 8601.
4031 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Fixed protocol error handling in client library. It should now
4034 cope even if the SKE fails for some reason.
4036 * Made new protocol specification drafts for submitting to IETF.
4038 * Implemented TOPIC command to server in silcd/command.c.
4040 * Added two new notify types into lib/silccore/silcnotify.h:
4041 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4042 notify nickname change and topic setting/change on a channel.
4044 * API change of command_reply operation in client library. The
4045 application gets now the status type received from server as well.
4047 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4049 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4051 * Cras fixed and optimized the packet handling even further and
4052 it should work now. Minor change to the prototype of function
4053 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4055 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4057 * Added new function into lib/silcutil/silcschedule.[ch]:
4058 silc_schedule_with_fd to select() a specified fd. The function
4059 returns after timeout expires or data arrives or goes. The
4060 function is used by packet routines to wait that all data is
4061 received from network.
4063 * Fixed data reading from network in lib/silccore/silcpacket.c.
4064 The code now assures that all data is read from the fd and then
4065 continues packet processing. This was a bug fix since the code
4066 used to drop some data in some circumstances.
4068 * Added new function into lib/silcclient/client.[ch]:
4069 silc_client_start_key_exchange to start key exchange after
4070 connection has been established to server. The code internally
4071 now uses this funtion but its main purpose was to provide it
4072 for applications that perform their own connecting. After
4073 application has created a connection it merely calls this
4074 function to start the key exchange between client and server.
4075 The library takes care of everything else after that.
4077 Updated also lib/silcclient/README to explain the usage of
4080 * Do not send to application information that connection has
4081 been established. Application gets notified it by connect
4084 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Applied cras's patch to add silc_schedule_one function. The
4087 function runs scheduler once and returns.
4089 * Fixed the scheduler after cras messed it up. The timeout
4090 handling works now as it's supposed to work.
4092 * Added into lib/silccore/ silcnotify.h to include notify
4093 message types support. Changed silc_server_send_notify*
4094 functions, in server.[ch], to support those new notify types.
4095 Added the support for the notify types into client library,
4096 as well. Added new notify client operation into ops.h in
4099 * Changed silc_server_packet_send_to_channel to send normal
4100 packets instead of just channel message packets. The function
4101 is now used to send the notify packets to channels. It is not
4102 used to send channel message packets anymore, as server never
4105 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4106 va_arg()s as it seems to require it nowadays. I guess, if SILC
4107 is compiled with older va_arg() the new code should work anyway.
4109 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Splitted core library. Core library (lib/silccore) includes
4112 now only SILC protocol specific core (and common) components.
4113 Created new utility library (lib/silcutil) that includes more
4114 generic purpose stuff. The stuff for util library was taken
4115 from the old core library. This was minor and easy split.
4117 * Created SILC Client Library (lib/silcclient) that includes
4118 implementation of the SILC client without user interface. This
4119 was major move from silc/ directory. The code has been changed
4120 so that it is transparent towards the user interface. The
4121 silc/ directory includes now the same user interface as before
4122 and it uses the new client library. Read lib/silcclient/README.
4123 Basicly, the client library performs everything else related
4124 to SILC except user interface handling. Also, configuration
4125 files are considered to be part of user interface and library
4126 does not handle them.
4128 This change also changed a lot of structures, function naming etc.
4129 Most important change was that SilcClientWindow object was
4130 renamed to SilcClientConnection in the client library. Created
4131 also new file lib/silcclient/ops.h. Also added new files
4132 silc/local_command.[ch] and silc/client_ops.[ch].
4134 All these changes were made to make it easier for user interface
4135 designers to create what ever user interface for the SILC client
4138 It is also expected that the server will be moved to lib
4139 directory as well and SILC Server Library will be created;
4140 sometimes in the future.
4142 * Removed Local commands from lib/silccore/silccommand.h as
4143 they are application specific and new client library does not
4144 handle any of those anymore.
4146 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4147 old client implementation in silc/.
4149 * Added support for callback functions in SILC_LOG_* macros.
4150 Application can now set its own callbacks that will be called
4151 instead of using the default functions that will always print
4152 the debug messages to stderr (or stdout). Also, debugging can
4153 now be disabled by setting silc_debug to FALSE and re-enabled by
4154 setting it to TRUE. Note, that logging will still work even
4155 if debugging is disabled.
4157 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4158 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4159 silc_log_reset_debug_callbacks.
4161 * To enable debugging in silc client one must give now -d
4162 option on command line.
4164 * Changed silc_schedule_init to automatically allocate task queues
4165 if they are not allocated before calling it.
4167 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Added GMP 3.1 into math library.
4171 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4173 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4174 a channel in SILC network. The packet is used by servers and
4175 routers to notify other routers that user has left a channel.
4176 This little feature was missing until now. Added the feature
4177 to protocol specification as well.
4179 Added functions: silc_server_send_remove_channel_user and
4180 silc_server_remove_channel_user into server.[ch].
4182 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4183 lib/silccore/silcpacket.h. However, they are not implemented
4186 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Fixed joining to a channel and sending channel messages
4189 between server and router. The channel message sending should
4190 now work inside a cell.
4192 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Fixed the private message sending between server and router.
4195 The private message sending should now work inside a cell.
4197 * Added silc_server_replace_id into server.[ch] to replace
4198 existing ID in the SILC network.
4200 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4201 and silc_idlist_replace_server_id into idlist.[ch] in server.
4203 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Fixed the server to server connections. Server can again now
4206 connect to router. Router to router connections probably does
4209 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4211 * Added dynamic protocol registering support. Now protocols can
4212 registered and unregistered on the fly. Patch by cras.
4214 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4216 * Added lib/contrib directory to hold routines that some platforms
4217 don't have but are needed by SILC.
4219 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4220 into lin/contrib to provide getopt() and getopt_long() for
4221 those who don't have it.
4223 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Added AWAY command to client. When away message is set and
4226 client receives a private message packet the client automatically
4227 replies to the sender with the away message.
4229 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4230 bug seemed to be the cause of recent problems when compiling
4233 * Added version detection support to SKE protocol specification
4234 and added the new changes to the SKE implementation as well.
4235 There were other minor changes in the SKE protocol as well.
4237 Many changes in lib/silcske/silcske.[ch] and in
4238 lib/silcske/payload.[ch].
4240 * Added ^U functionality, clear input line. Patch from cras.
4242 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Mainly small bugfixes on core library. Fixed some debugging
4245 logging and buffer overflow in silclog.c.
4247 * Updated config.sub and config.guess on the distribution tree.
4249 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Added command lagging support in server. Client may execute
4252 commands now only once in two seconds.
4254 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Optimized packet reception. MAC computation and checking is now
4257 also more optimized. A lot previously duplicated code is now
4258 used as generic by both client and server.
4260 * Fixed key pair generation in clientutil.c
4262 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4264 * Added into lib/silccore/silcbufutil.[ch] new function;
4265 silc_buffer_realloc.
4267 * Moved generic packet sending/encryption functions to
4268 lib/silccore/silcpacket.[ch] from client and server. Some
4269 rewriting of the functions.
4271 * Moved all generic packet reception/decryption functions to
4272 lib/silccore/silcpacket.[ch] from client and server. The
4273 packet processing is now much cleaner in both client and server.
4274 These were major changes in both client and server.
4276 * Created many common functions in server to do packet sending.
4277 Previously code were duplicated a lot, this has been removed
4280 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Rewrote major parts of the ID cache system. Don't know
4283 whether it is better now or not but at least the API is more
4286 * Major rewrite on ID cache stuff on client because of the ID
4287 cache API changes. Added idlist.c to client.
4289 * Also major rewrite on ID cache stuff on server as well.
4290 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4291 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4292 in hand, instead they are all put into the ID cache system now.
4293 All server_idlist_* routines uses ID cache now instead of
4294 traversing its own lists (those lists does not exist anymore).
4295 SilcIDList though still exists. Also, SilcXXXEntry's are
4298 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Finally made the SKE implementation compliant to the protocol
4301 specification. All mp integers are now binary encoded as
4302 opposed being HEX encoded.
4304 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4307 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4308 functions: silc_[encode/decode]_pem. Also added function
4309 silc_encode_pem_file to PEM encode with newlines ('\n') for
4312 * SILC public keys are now encoded either PEM or binary. Same
4313 option is for private keys as well. By default private keys
4314 are binary encoded and public keys PEM encoded. Silly HEX
4315 encoding were removed.
4317 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4318 function to create fingerprints.
4320 * Fixed a bug in SHA1; does not change the original data anymore.
4322 * Partly implemented INFO command on client and server side.
4323 Fixed CLEAR command. Changes to SERVER command; show current
4324 server(s) when giving command without arguments. Added
4325 VERSION command to client.
4327 * Added check to server that unregistered connections cannot
4328 execute commands (unless it is specificly allowed).
4330 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Fixed screen refresh.
4334 * Fixed channel joining bug from client. On some circumstances
4335 client tried to join to a channel it had already joined.
4337 * Added public key verification process into client's protocol.c.
4338 The client now verifies the public key from user and saves
4339 it into ~./silc/serverkeys/ directory.
4341 Added into: clientutil.[ch]: silc_client_verify_server_key.
4343 * Changed SKE protocol's silc_ske_initiator_finish function
4344 to accept callback function that verifies the received public
4345 key. Removed old silc_ske_verify_public_key function.
4347 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4350 silc_pkcs_private_key[_data]_set.
4352 * Made the password and public authentication more cleaner in
4353 server's protocol.c.
4355 * Removed historic and obsolete protocol `channel_auth' from
4356 both client and server.
4358 * Removed wrong way of sending command status messages from
4359 server to client in server's command.c. The old way violated
4360 protocol specification.
4362 Changes to silccore/silccommand.[ch]: removed
4363 silc_command_encode_status_payload -> not needed anymore,
4364 changed silc_command_encode_payload_va to accept extra
4365 argument on variable argument list. The argument type must
4366 now be provided to the function. Also, added new function:
4367 silc_command_encode_reply_payload_va which is same as
4368 normal command_encode_payload_va except command status type
4369 is provided as extra argument.
4371 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Added ~./silc directory handling. The directory includes the
4374 public and private keys for the client.
4376 Added silc_client_check_silc_dir, silc_client_create_identifier
4377 and silc_client_load_keys.
4379 * Implemented SILC protocol compliant public key. Added public
4380 and private key saving to and loading from files.
4382 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4383 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4384 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4385 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
