1 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Changed the dynamic tables to static size tables in the
4 lib/silccrypt/silchmac.c.
6 * Removed GCC dependencies from the code. A patch by cras.
8 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
10 * Do not show the error "Error receiving packet bla bla"
11 in server if it really was not an error (-2 means that reading
12 is pending). Affected file silcd/server.c.
14 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
16 * Fixed a possible crash in silc_server_remove_clients_by_server
17 in silcd/server.c. Fixed there also some memory leaks.
19 * Fixed the silc_idlist_replace_client_id. It could replace
20 wrong key in the hash table. Affected file silcd/idlist.c.
22 * Do not check whether there are global users on the channel
23 if the channel->global_users is FALSE. Affected functions
24 silc_server_remove_from_one_channel and
25 silc_server_remove_from_channels in silcd/server.c. Also,
26 do not check if the removed client is local as we can be
27 sure that global client was not removed from the channel
28 and checking for global users is not needed.
30 * The silc_server_remove_clients_by_server now re-generates
31 the channel keys correctly for those channels that had
32 clients removed from them. Affected file silcd/server.c.
34 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
36 * Found the reason of random crashes in the server. We weren't
37 ignoring the SIGPIPE signal (which can be sent in write())
38 and it crashed the server. Affected file silcd/silcd.c.
40 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
42 * Assure that sock->user_data is not NULL in the function
43 silc_server_packet_send in silcd/packet_send.c.
45 * Disconnect the remote connection if it could not be added
46 to any ID lists in the server. The affected file is
49 * Check in silc_server_packet_send[_real/dest] that the
50 socket is not disconnecting and ignore the data if it is.
51 Affected file silcd/packet_send.c.
53 * Define inline to __inline on native WIN32 compilation.
54 Affected file includes/silcwin32.h.
56 * Added some explicit type casts for inline code since MSVC
57 require them. Affected files lib/silcutil/silcbuffer.h,
58 lib/trq/silcdlist.h and lib/trq/silclist.h.
60 * Print warning in log files from now on if the packet
61 decryption fails. Affected file silcd/server.c.
63 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
65 * Changed the `say' client operation's interface to accept
66 new `type' argument to indicate the type of the message sent
67 by the library. The application may filter the library's
68 messages according the type. The affected file is the
69 lib/silcclient/silcapi.h.
71 * Added two new functions to lib/silcclient/silcapi.h:
72 silc_client_del_client and silc_client_del_client_by_id.
73 Affected file lib/silcclient/idlist.c.
75 * Moved the clientincludes.h from includes/ to silc/ and
76 serverincludes.h from includes/ to silcd/.
78 * The modes for the CMODE and CUMODE are now passed as
79 uint32 for application with COMMAND_REPLY. The affected
80 file is lib/silcclient/command_reply.c.
82 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
84 * /WHOIS without arguments shows client's own information.
85 Affected file lib/silcclient/command.c.
87 * Changed PING to not accept any arguments. The specs
88 says that client can ping only the connected server so
89 requiring an argument is not needed. Affected file is
90 lib/silcclient/command.c.
92 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
94 * Fixed a fatal bug in private message sending and reception
95 encryption and decryption when using private message keys.
96 The implementation was incorrect and did not follow the
97 specification. It causd that some of the message were
98 lost since it did not use the sending and receiving keys
99 as the protocol suggests. This has been fixed and will cause
100 incompatibilities with older clients when sending private
101 message encrypted with private message keys. Affected files
102 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
103 and various other in Irssi SILC Client.
105 Added `responder' boolean argument to the functions
106 silc_client_add_private_message_key[_ske] to indicate when
107 the key is added as responder or initiator of the key
110 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
112 * Removed the silc_ske_check_version function and created
113 a SilcSKECheckVersion callback. Added also a function
114 silc_ske_set_callbacks that is now used to set all SKE
115 callbacks. The callback functions are not given to
116 the SKE functions anymore, but this function is used to
119 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
121 * Added `silc_version' argument to the silc_client_alloc
122 to define the version of the application for the library.
123 The library will use the version string to compare it
124 against the remote host's (usually a server) version
125 string. Affected file lib/silcclient/silcapi.h
127 * Added the KE protocol context to Key Agreement context
128 in client library so that we can abort the SKE if it
129 is in process when we get timeout. Affected file is
130 lib/silcclient/client_keyagr.c.
132 * Do not resolve the client ID forever if it returns in the
133 first time that such client does not exist. This was done
134 for example with private message. Affected file is
135 lib/silcclient/client_prvmsg.c.
137 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
139 * Do not add regex.h for WIN32. The affected file
140 includes/silcincludes.h.
142 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
143 not work yet 100%. It generates the DLL's automatically
144 when compiling with --with-win32 under cygwin.
146 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
148 * lib/contrib/regex.c is not compiled on WIN32.
150 * Added silc_net_get_socket_opt function to the
151 lib/silcutil/silcnet.h.
153 * Added includes/silcwin32.h for WIN32 specific includes
156 * Do not use ptime structure or any of the posix process
157 functions on WIN32 in lib/silccrypt/silrng.c.
159 * Added silc_gettimeofday to provide generic function
160 for struct timeval on all platforms. Added the function
161 to lib/silcutil/silcutil.h.
163 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
165 * Moved the lib/silccore/silcsockconn.[ch] to the utility
166 library as they clearly belong there. As a plus side we
167 can make the actual socket connection routines platform
170 Added also new generic function silc_socket_read and
171 silc_socket_write (that used to be silc_packet_[read/write].
172 The implementation of these are platform specific.
174 * Added WIN32 specific routines of silc_socket_[read/write]
175 to lib/silcutil/win32/silcwin32sockconn.c.
177 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
179 * Added preliminary support for native WIN32 compilation under
180 cygwin (using the -mno-cygwin option for GCC) to the
181 ./configure.in.pre. The --with-win32 now prepares the
182 compilation for native WIN32.
184 * Rewrote the SILC Scheduler interface in the file
185 lib/silcutil/silcschedule.h. The scheduler is now context
186 based and does not have anymore any global static scheduler.
187 Moved the Unix scheduler to the lib/silcutil/unix/ directory
188 and created lib/silcutil/win32 directory for WIN32 based
191 * Added Unix specific network routines to the
192 lib/silcutil/unix/silcunixnet.c and the old
193 lib/silcutil/silcnet.c includes now only generic routines.
195 Added WIN32 specific network routines to the
196 lib/silcutil/win32/silcwin32net.c.
198 * Added Unix specific utility functions from the
199 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
201 * Added WIN32 SILC Scheduler to the file
202 lib/silcutil/win32/silcwin32schedule.c. The code is of course
205 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
207 * Do not handle JOIN notify in the server if the target client
208 is not registered (idata->registered == FALSE). The affected
209 file is silcd/packet_receive.c.
211 * Update the nickrec->founder in event_cumode in the Irssi SILC
212 client. Affected file irssi/src/silc/core/silc-channels.c.
214 * Fixed the CUMODE_CHANGE notify handling in the server when
215 server and router are announcing their clients on channels.
216 Now the mode changes are saved and notified correctly. The
217 affected file is /silcd/packet_receive.c.
219 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
220 They really did not replace the cache entry in the ID Cache.
221 Now they do that. Affected file silcd/idlist.c.
223 * Fixed the KICK notify handling in the Irssi SILC client to
224 update the channel records so that the kicked client does not
225 appear to be on the channel. The affected file is
226 irssi/src/silc/core/silc-channels.c.
228 * Always update the conn->current_channel when executing command
229 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
231 * Fixed the KILL notify handling in Irssi SILC client to remove
232 the killed client on all channels.
234 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Fixed the silc_parse_command_line to remove extra spaces
237 from the start and end of the arguments. Affected file is
238 lib/silcutil/silcutil.c.
240 * Cancel and free any active protocol in the function
241 silc_server_close_connection. Affected file silcd/server.c.
243 * Cancel and free any active protocol in the function
244 silc_client_close_connction. Affected file is
245 lib/silcclient/client.c.
247 * Do not execute the KILL command for clients that are in
248 history (ie. they are not in the network). Affected file is
251 * Fixed KILL notify handling, client does not crash anymore.
252 Affected file irssi/src/silc/core/silc-channels.c.
254 * Reduced the default packet buffer size from 2048 to 1024 in
255 lib/silccore/silcpacket.c.
257 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
258 counter to the SKE context that is incresed when the SKE library
259 performs async operation outside the library. If the outside
260 process frees the SKE context and FREED status will be set
261 and the library will detect after the sync operation that the
262 libary is freed. The affected files are
263 lib/silcske/silcske[_status].[ch].
265 * Resolve the client entry information in the function
266 silc_client_channel_message to assure that NULL pointer is not
267 passed as client entry to the application. */
269 * Fixed the task timeout calculation to assure that there is
270 never negative timeouts. The affected file is
271 lib/silcutil/silcschedule.c.
273 * Fixed the channel user mode notification sending in server.
274 It was sent point-to-point to the router (or to server by router)
275 but it needs to be destined to a channel. The routines now
276 supports sending the channel user mode notifys to the channels
277 when announcing clients and channels. Affected files are
278 silcd/server.c and silcd/packet_receive.c.
280 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
281 It did not actually replace the old channel entry in the cache.
282 Affected file lib/silcclient/client_notify.c.
284 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
286 * Fixed a possible crash in silc_packet_send_prepare. It now
287 assures always that there is enough space in the buffer and
288 at the tail area of the buffer (for MAC).
290 Fixed the inbound buffer reallocation in silc_packet_read.
291 It was old code and did not handle the reallocation correctly.
294 The affected file is lib/silccore/silcpacket.c.
296 * Fixed buffer overflow in silc_parse_nickname in the file
297 lib/silcutil/silcutil.c.
299 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
301 * make install generates new server keys only if there is not
304 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
306 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
307 Added check that if the NOREPLY is set then we will not send
308 the away message. This avoids infinite loop of away messages
309 if both clients are away. The affected file is
310 lib/silcclient/client_prvmsg.c.
312 * Fixed client crash if /NICK was given without arguments.
313 Affected file lib/silcclient/command.c.
315 * Server does not send the invite list in INVITE command back
316 to the client if the list was not altered. Added this notion
317 to the protocol spec as well. Affected file silcd/command.c.
319 Fixed possible crash in INVITE command by checking the
320 value of silc_server_get_client_route command.
322 * Fixed the INVITE notify type handling. The arguments are now
323 taken in correct order and client does not crash. The affected
324 file is irssi/src/silc/core/silc-channels.c.
326 Removed the "Inviting xxx to channel" message from the
327 client library away and let the application handle it.
328 Affected file lib/silcclient/command.c. Added that message
329 to Irssi SILC client's message formats.
331 * Fixed CMODE command crash in client. It now checks the
332 amount of arguments correctly and does not crash. The affected
333 file is lib/silcclient/command.c.
335 * Do not create new channel automatically in silc_channels_join
336 but check whether the channel by that name already exists.
337 Affected file irssi/silc/core/silc-channels.c.
339 * Do not send the SERVER_SIGNOFF to router if the disconnected
340 entity was the router. Affected file silcd/server.c.
342 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
343 SILC client as it was missing from there.
345 Added the handling of the KICK notify to the Irssi SILC client
346 as it was missing. Added "you have been kicked" message to
347 Irssi SILC client's message modules formats.
349 Added the handing of the KILL notify to the Irssi SILC client
350 as it was missing. Added the kill message module formats
353 The affected file is irssi/src/silc/core/silc-channels.c.
355 * The router did not save the channel mode the server announced.
356 Affected file silcd/packet_receive.c.
358 * Fixed a possible crash in INFO command in server. If the
359 server did not provide the server info it crashed. Affected
360 file silcd/command.c.
362 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Fixed the GETKEY command in the server to check also the
365 global list. Otherwise the GETKEY would not work correctly
366 in normal SILC server. Affected file silcd/command.c.
368 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
370 * Fixed GETKEY crash, it crashed if the command did not succseed.
372 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
374 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
375 is now real and not just an macro interface to GMP.
377 Removed the entire GMP from the source tree and imported new
378 NSS MPI library instead. Reason for removing GMP is that it is
379 extremely large and compiles extremely slow. The NSS MPI
380 is only a few files and compiles in less than 10 seconds.
381 The speed is also about the same as GMP. The MPI is imported
384 If the system has GMP installed we will still use the GMP.
385 If it is not then the NSS MPI will be compiled.
387 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
389 * Merged a long nickname (127 characters long) crash bugfix from
390 Irssi CVS tree. Affected file irssi/src/core/misc.c.
392 * Merged a freed memory reference bugfix from Irssi CVS tree.
393 Affected file irssi/src/core/commands.c.
395 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
397 * Added the server's public key sving and verification to the
398 server when performing the SKE. This was missing and the
399 remote server's (or router's) public key was accepted without
400 checking whether we have it previously or trust it at all.
401 Affected file silcd/protocol.c.
403 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
405 * Check in the silc_server_timeout_remote if protocol is active
406 and make sure that the protocol's final callback is called so
407 that all memory if freed. Affected file silcd/server.c.
409 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
411 * silc_server_whois_send_reply crashed the server if the nickname
412 was 127 characters long. Affected file silcd/command.c.
414 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
416 * Added sanity check to the silc_server_new_client. If the hostname
417 is provided inside username then check that the provided hostname
418 really is the same as the resolved one. If the hostname was not
419 resolved then check it from the public key. Affected file is
420 silcd/packet_receive.c.
422 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
423 if the server disconnected us and the connection is not valid
424 anymore. Affected file irssi/src/silc/core/silc-channels.c.
426 * Moved the silc_client_[chmode|chumode|chumode_char] away from
427 the library to the lib/silcutil/silcutil.[ch].
429 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
431 * Close log file after open. Affected file
432 lib/silcutil/silclog.c.
434 * Check whether sock == NULL in silc_client_send_packet and return
435 if it is. Affected file lib/silcclient/silcclient.c.
437 * Check rec->entry == NULL in the Irssi SILC Client before
438 sending the channel message. Affecte file is
439 irssi/src/silc/core/silc-servers.c.
441 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
443 * Merged a splitted window bugfix from Irssi CVS tree. The
444 affected file is irssi/src/fe-text/textbuffer-view.c.
446 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
447 It did not print nickname.
449 * Improved the distributions system a bit.
451 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
453 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
454 irssi/src/fe-text/gui-window.c.
456 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
457 to in-active server. The affected file is
458 irssi/src/silc/core/client_ops.c.
460 * Resolve the client in USERS command reply if the entry does
461 not have username resolved. The affected file is
462 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
463 command to WHOIS command to really resolve stuff. The USERS
464 is not used any more in any critical section so WHOIS can
465 be used even though it might be slower than IDENTIFY.
467 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
470 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
472 * Changed the protocol API a bit more consistent in the
473 lib/silccore/silcprotocol.[ch].
475 * Changed the following headers to ROBODoc format:
477 lib/silccore/silcpayload.h
478 lib/silccore/silcprotocol.h
479 lib/silccore/silcsockconn.h
481 All core library headers are now formatted.
483 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
485 * Fixed a bug in Irssi SILC client; do not show that you are
486 server/router operator if you really are not. Affected file is
487 irssi/src/silc/core/client_ops.c.
489 * Renamed silc_command_free_payload to silc_command_payload_free.
490 Affected file lib/silccore/silccommand.h
492 * Added silcmath.h to include the prototoypes of various routines
493 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
496 * Changed the following headers to ROBODoc format:
498 lib/silccore/silcchannel.h
499 lib/silccore/silccommand.h
500 lib/silccore/silcid.h
501 lib/silccore/silcidcache.h
502 lib/silccore/silcmode.h
503 lib/silccore/silcnotify.h
504 lib/silccore/silcpacket.h
505 lib/silcmath/silcmath.h
507 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
509 * Added checking to the server code not to start the server if
510 ciphers and stuff are not configured properly. Affected files
511 silcd/serverconfig.[h] and silcd/server.c.
513 * Changed the layout of the header files of the public interfaces
514 in the SILC libraries. The new layout supports ROBODoc
515 documentation tool (and some others) so that it is easy to create
516 a library reference manual. All the other headers and source
517 code must still follow the CodingStyle document. Also source
518 code must not include these ROBODoc stuffs, only the headers.
519 Furthermore, all public interface headers must now be named
520 by using `silc' prefix, example: silcapi.h, silccipher.h.
521 Some files were renamed due to this. All the other headers
522 must not be used as public interfaces. I will update the
523 CodingStyle document later. Changed following headers, so far:
525 lib/silcclient/silcapi.h
526 lib/silccore/silcauth.h
527 lib/silccore/silcprivate.h
528 lib/silccrypt/silcdh.h
530 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
534 * Removed silc_client_packet_send_flush from the client library
535 as it is not needed. Affected file lib/silcclient/client.[ch].
537 * Added printing of message of unresolved authentication method
538 to the Irssi SILC client. Added it to the module formats.
539 Removed the same message from the client library.
541 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Added new distribution feature, DISTLABEL. Every distribution
544 can define own preprocessor label that can be used in the
545 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
546 file distributions, acconfig.h.pre and prepare.
548 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
550 * Added Makefile.defines_int to include the actual definitions
551 for Makefile.defines.in. Tested the new distribution system,
552 created distributions and tested installation.
554 * Added AWAY message printing to the Irssi SILC client. Added
555 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
557 * Added SCONNECT command to call the SILC's CONNECT command.
558 Cannot use CONNECT directly since Irssi uses that internally.
559 Affected file irssi/src/silc/core/silc-servers.c.
561 Added ACTION local command. It is same as ME command but takes
562 the channel as mandatory argument.
564 Rewrote some of the Irssi's help files to suite for SILC
567 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
569 * Added Makefile.defines[.in] that should for now on be included
570 in all Makefile.am file in the source tree. That file includes
571 all common compilation definitions for SILC source tree.
573 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
575 * Minor changes to the ./prepare script to change the package
576 name according the distribution name to the configure.in.
578 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
580 * Created new distribution system. Added file `distributions'
581 that defines all the distributions that can be created out of
582 the SILC source tree. The ./prepare script now reads that
583 file to determine how to prepare the distributions. The
584 first argument to the ./prepare is the name of the distribution
585 and second is the version of the distribution. If given
586 without arguments it creates the default (toolkit) distribution
587 with the default version (defined in ./prepare).
589 All Makefile.am files that are subject to the distributions
590 are now named as Makefile.am.pre. These are ./Makefile.am
591 and lib/Makefile.am. Others may be changed later.
593 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
595 * Added invite list, ban list, some key management and connection
596 error message printing to module formats in the Irssi SILC client.
598 * Added new silc_client_set_away_message to set the away message
599 that is back to the person who sent private message. The
600 affected file lib/silcclient/silcapi.h and the
601 lib/silcclient/client_prvmsg.c.
603 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
605 * Fixed the private message sending in the Irssi SILC client,
606 added local command KEY to the Irssi SILC client.
608 Added key management and key agreement message formats to the
609 irssi/src/fe-common/silc/module-formats.[ch].
611 Added USERS (alias WHO) printing, server/router operator
612 indication and LIST command printing to the module formats.
614 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
616 * Fixed channel joining notify handling, cumode notify handling
617 from Irssi SILC client.
619 * Added SILC specific module-formats to the Irssi SILC client so
620 that SILC specific message hilighting, colors etc is possible.
621 Affected file irssi/src/fe-common/silc/module-formats.[ch].
623 Added channel mode, channel user mode, actions, notices,
624 whois and whowas printing to the the module-formats.c.
626 * Fixed a bug in channel deletion in the server. The channel
627 is not left to the cache even if the channel founder auth mode
628 is set when there are no users anymore on the channel. Affected
631 * The silc_net_localhost now resolves the entire hostname including
632 the domain name. Affected file lib/silcutil/silcnet.c.
634 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
636 * Changed the ask_passphrase client operation to be ascynchronous.
637 It has now a completion callback and a context that the
638 application must call after it has got the passphrase from
639 the user. Affected files lib/silcclient/silcapi.h,
640 lib/silcclient/protocol.c, lib/silcclient/command.c and
643 Added SilcAskPassphrase callback that the application calls
644 to deliver the passphrase to the library.
646 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
647 The public key verification and especially a certificate
648 verification is asynchronous procedure.
650 Added new SILC_SKE_STATUS_PENDING status to indicate the
651 request is pending and a callback will be called to finalize
654 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
655 indicate that remote end did not send its public key (or
656 certificate), even though we require it. Added check for this
657 condition in the SKE. This was a security bug, now fixed.
659 Defined new SilcSKEVerifyCbCompletion callback that is called
660 when the verification process is completed.
662 The affected files lib/silcske/silcske_status.h and
663 lib/silcske/silcske.[ch].
665 * Changed the verify_public_key client operation to be async
666 as well. Defined SilcVerifyPublicKey callback that is used to
667 indicate the success of the public key verification process.
669 Changed the server and client to use the new async client
672 * Changed the Irssi SILC client's internal scheduler to be called
673 twice as many times as it used to be. As a result the client
674 should be a bit faster now. Affected file is
675 irssi/src/silc/core/silc-core.c.
677 * Added support to Irssi SILC client of asynchronous public key
678 verification and passphrase inquiry. Affected file is
679 irssi/src/silc/core/silc-core.c.
681 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
683 * Do not say "You have left channel %s" in client library.
684 Moved it to the application. Affected files are
685 lib/silcclient/command.c and silc/client_ops.c.
687 * Fixed silc_client_get_clients. Command context was not
688 duplicated and was freed memory in the callback. Affected
689 file lib/silcclient/idlist.c.
691 * Do not say "you are now talking..." on JOIN command in the
692 client library. The appliation must handle it.
694 * Do not say ".. changed topic to" in command reply in the
695 client libary. The application must handle it.
697 * Fixed TOPIC command sending in the client library.
699 * Fixed a memory leak in silc_client_command_free in the file
700 lib/silcclient/command.c.
702 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Imported a modified version of Irssi client to the source tree.
705 The Irssi will be used to create a new client called
706 Irssi SILC. Imported to irssi/.
708 Added silc_core_init_finish function to the Irssi. Affected
709 file irssi/configure.in.
711 A lot changes in the Makefile.ams around the irssi tree.
713 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
715 * Do not rehash if the new size is same as the old size of the
716 hash table, in the silc_hash_table_rehash*. The affected file
717 lib/silcutil/silchashtable.c.
719 * Replaced hash_table_del_by_context calls from the server
720 (when channel->user_list and client->channels) to the
721 hash_table_del as it is sufficient and faster.
723 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
725 * Added silc_hash_table_list, silc_hash_table_get and the
726 SilcHashTableList structure to provide an alternative way to
727 traverse the hash table. The affected files are
728 lib/silcutil/silchashtable.[ch].
730 * Changed the server's idlist routines to use the hash table
731 routines to optimize the code.
733 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
735 * Replaced the client entry's `channel' list and channel entry's
736 `user_list' list to hash tables for optimized lookup. Changed
737 the code to use the hash table interface around the code.
738 Affected file lib/silcd/idlist.[ch].
740 * Added `auto_rehash' boolean argument to the function
741 silc_hash_table_alloc to indicate whether the hash table should
742 auto-rehash when it thinks is appropriate time. It will
743 increase the hash table size if the there is twice as much
744 entries in the table than the size of the table, and will
745 decrease the size if there are twice as less entries than
746 the size of the table.
748 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
750 * Fixed silc_xxx_get_supported to not crash at some circumstances.
752 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
754 * silc_idcache_purge_by_context deletes the entry now by context
755 as it is supposed to do. Affected file lib/silccore/idcache.c.
757 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
758 client is not anymore valid (WHOWAS givens the info) and not
759 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
761 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
763 * Removed the `data' and `data_len' arguments from the ID Cache
764 interfaces and added `name' argument. ID Cache does not handle
765 anymore the binary data only a names associated with given ID.
767 * When hashing a Client ID with silc_hash_id the entire ID is
768 not hashed anymore, instead only the hash of the Client ID is
769 hashed. This way we can access the Client ID from the cache
770 with Client ID but with the hash of the ID (which is a hash of
771 the nickname) as well without any difference in performance.
773 Added also silc_idcache_find_by_id_one_ext to do one on one
774 searching when we have the actual ID. Added also function
775 silc_hash_client_id_compare. The affected files are
776 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
778 * When hashing the name associated with a ID it is always done
779 in lowercase. This way we can access the cache without worrying
780 about case-sensitivity, even though, for example nicknames are
783 * Fixed a bug in server with channel message sending. It put
784 wrong ID type as destination ID. The affected file
787 * silc_idcache_del_by_context now deletes from all hash tables
788 by context. Affected file lib/silccore/idcache.c.
790 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
792 * Changed the client library to use the new ID Cache interface.
793 Changes around the source tree.
795 * Added silc_hash_table_rehash_ext to rehash with specific
796 hash function. Affected file lib/silcutil/silchashtable.[ch].
798 * Added silc_hash_string_compare to compare two strings in the
799 hash table. Affected file lib/silcutil/silcutil.[ch].
801 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
803 * Added new function silc_idcache_del_by_context into the
804 lib/silccore/idcache.[ch].
806 * Changed the server's ID list routines to use the new ID Cache
807 interface. Changes around the source tree.
809 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
811 * Added silc_hash_table_del[_by_context]_ext functions in to the
812 lib/silcutil/silchashtable.[ch].
814 Removed silc_hash_table_find_all* routines and added new
815 silc_hash_table_find_foreach to replace them.
817 Added silc_hash_table_replace_ext function as extended
818 replacing function. Separated the simple hash table interface
819 from the extended hash table interface in the file
820 lib/silcutil/silchashtable.h.
822 * Fixed minor bugs and changed it to use some of the new
823 hash table functions in lib/silccore/idcache.c
825 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
827 * Added new function silc_hash_table_find_all to return all keys
828 in the hash table by the specified key. As the hash table is
829 collision resistant it also makes it possible to have several
830 duplicate keys in the hash table. This function may be used to
831 find all of the keys from the hash.
833 Added user_context arguments to the SilcHashFunction,
834 SilcHashCompare and SilcHashDestructor to deliver user specified
837 Added new fuctions silc_hash_table_find[_all]_ext to do
838 extended lookup with specified hash and compare functions and
839 specified user contexts.
841 Added new function silc_hash_table_add_ext to add the key
842 with specified hash function and user context.
844 Added new function silc_hash_table_foreach to traverse all
845 entrys in the hash table. Added SilcHashForeach callback
848 Added new function silc_hash_table_del_by_context to delete
849 the entry only if the context associated with the key matches.
851 Affected files are lib/silcutil/silchashtable.[ch].
853 * Removed silc_hash_[server/client/channel]_id and added just
854 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
855 silc_hash_id_compare to compare two ID's using as the hash table
856 comparison function. Added also silc_hash_data to hash
857 binary data and silc_hash_data_compare to compare it.
859 * Removed silc_idlist_find_client_by_hash as it is not needed
860 anymore. Affected file silcd/idlist.[ch].
862 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
863 to use internally the SilcHashTable. The new ID Cache is a lot
864 faster than the old one. Some of the ID Cache interface was also
865 rewritten and obsolete and stupid functions were removed.
867 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
869 * Added entry_count field to the SilcHashTable to keep the number
870 of the entries in the table. Implemented the function
871 silc_hash_table_rehash. Added new function
872 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
874 Fixed a minor bug in silc_hash_table_free.
876 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
877 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
878 into the lib/silcutil/silcutil.[ch].
880 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
882 * Implemented a collision resistant hash table into the
883 lib/silcutil/silchashtable[ch]. See the header and the source
884 for the SilcHashTable API.
886 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
888 * Merged dotconf version 1.0.2 into lib/dotconf.
890 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
892 * Do not compile anything in lib/silcsim/* if the SIM support
893 is not enabled. The tree should now compile without problems
896 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Compiled the SILC under cygwin. Compiled and tested briefly
899 without problems. More tests needed. The SIMs didn't compile
902 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
904 * Fixed possible crash in silc_get_username in the
905 lib/silcutil/silcutil.c.
907 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * Fixed a va_arg in silc/client_ops.c.
911 * Oops, RC5 routines were named AES and caused some problems
912 when not using SIM's. Affected file lib/silccrypt/rc5.c.
914 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Added new SilcIDIP structure into the lib/silccore/id.h and
917 replaced the old `ip' fields from all SILC ID's to that type.
918 This is a step towards IPv6 support.
920 The silc_id_get_len takes now the ID as an extra argument.
921 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
922 both IPv4 and IPv6 based ID's.
924 The affected files are lib/silccore/id.[ch] and other files
925 around the tree using these routines.
927 * Removed the ID length arguments in server from various
928 silc_server_send_notify_* routines -> they are not needed
931 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
933 * Fixed memory leak in silc_encode_pem_file in the file
934 lib/silcutil/silcutil.c.
936 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
938 * Check minor version as well in the SKE. Affected files are
939 silcd/protocol.c and lib/silcclient/protocol.c.
941 * Added --identifier option to the server so that an identifier
942 can be when creating the public key for the server. Affected
943 file is silcd/silcd.c.
945 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
946 lib/silccrypt/silcpkcs.c.
948 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
950 * Register default ciphers and stuff when using -C option with
951 the server. Affected file sildc/silcd.c.
953 * Put back the servers public key filename format, it is better
954 than the new one. For now, the client keys are saved with the
955 new filename format. The affected file silc/client_ops.c.
957 * Implemented the Cipher API for the rest of the ciphers that
958 did not implement it or implemented it the wrong way.
960 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
962 * Register default ciphers and stuff when using the -S option
963 in the client. Affected file silc/silc.c. Same also when
964 creating new key pair with -C option.
966 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
968 * Fixed the silc_verify_public_key client operation function to
969 save the public keys differently. The fingerprint is now
970 used as filename and not the hostname. This way also the
971 client keys are saved uniquely and not with hostnames. The
972 affected file is silc/client_ops.c.
974 * Trimmed the silc_hash_fingerprint function to remove extra
975 whitespaces from the end of the fingerprint. The affected
976 file is lib/silccrypt/silchash.c.
980 * Added silc_cipher_register_default function to register all
981 default ciphers. It can be used when configuration files
982 does not exist and the application does not want any specific
983 ciphers in any specific order.
985 The SilcDList is now used as silc_cipher_list dynamically
986 allocated cipher list. Removed the static list all together
987 and now all ciphers must be allocated to the dynamic list.
988 The silc_cipher_alloc routine was changed to check only the
991 All silc_cipher_* routines that used to return int returns
994 The affected files lib/silccrypt/silccrypt.[ch].
996 * The same thing was done to silc_hash_* as for silc_cipher_*
997 routines. Affected files lib/silccrypt/silchash.[ch].
999 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1000 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1001 Added also silc_pkcs_[un]register[_default] functions.
1002 Removed the data_context from the PKCS API.
1004 * Added silc_hmac_register_default function to register default
1005 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1006 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1007 to unregister all hmacs at once.
1009 * Register the default ciphers, hash functions, PKCSs and HMACs
1010 if client's configuration file does not exist. The affected
1013 * The client did not load the hash functions from the SIM
1014 modules at all. Added support for this. Affected file is
1015 silc/clientconfig.c.
1017 * When decoding public key with silc_pkcs_public_key_decode, check
1018 the supported algorithm only if PKCS are registered. Affected
1019 file lib/silccrypt/silcpkcs.c. The same was done with the
1020 silc_pkcs_private_key_decode.
1022 * Fixed the SILC List routines to keep the list always in order.
1023 It used to change the list's order when traversing the list but
1024 not it preserves the order. Affected file lib/trq/silclist.h.
1026 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1028 * Added the client library to use the SilcSocketConnection's
1029 reference counter (by silc_socket_dup) to prevent the bug that
1030 the socket object may be freed underneath async operation.
1032 * The name resolv library checking fixes in the configure.in.pre.
1035 * Created new version of the protocol drafts for future
1036 development. The -03 drafts are the ones that will be changed
1037 in the trunk now and the -02 will remain as they are.
1039 * Send list of CUMODE notifys to the router when announcing
1040 the channel users to the router. Affected file silcd/server.c.
1041 If the router receiving channel founder CUMODE for a channel
1042 that already has channel founder it will send CUMODE notify
1043 to the sender to remove the channel founder rights from the
1044 announced client. Affected file silcd/packet_receive.c.
1046 * The CUMODE notify may now use Server ID as well as the entity
1047 who changes the mode. Updated protocool specs.
1049 * Updated INSTALL and README files.
1051 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1053 * New web pages in the http://silc.pspt.fi. The pages was
1058 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1060 * Implemented the [DenyConnectin] config section in the server.
1061 Added silc_server_config_denied_conn to check whether incoming
1062 connection is denied. Affected file silcd/serverconfig.[ch].
1064 * Do not check the ports when checking the incoming configuration
1065 data if the port is 0, meaning any. Affected file is
1066 silcd/serverconfig.c.
1068 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1070 * Fixed buffer overflow in silc_string_compare in the file
1071 lib/silcutil/silcutil.c.
1073 * Fixed double free in silc_server_command_leave in the file
1076 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1078 * Fixed the version checking in the server. Affected file is
1081 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1083 * Fixed the configuration data fetching when accepting new
1084 connections in the server. Affected file silcd/server.c.
1086 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1088 * Added `sender_entry' argument to the function
1089 silc_server_packet_relay_to_channel so that we can check
1090 whether some destination actually belongs to the same route
1091 the sender belongs (ie, we must not resend the packet to the
1092 sender). Affected file silcd/packet_send.[ch].
1094 * Added `servername' field to the SilcClientEntry in the server
1095 to hold the name of the server where client is from. Affected
1096 file is silcd/idlist.h.
1098 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Moved the channel message encrypting in the router betwen
1101 router connections from silc_server_channel_message to the
1102 silc_server_packet_relay_to_channel since we want to check
1103 whether we have anybody channel before encrypting anything.
1104 Affected files silcd/packet_[receive/send].c.
1106 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1108 * Fixed the [AdminConnection] server config section to support
1109 multiple entries. Affected file silcd/serverconfig.c.
1111 * Added support into the server to check the validity of the
1112 incoming connection before executing any KE or authentication
1115 * The connection configuration is now saved to the KE and
1116 connection auth protocol contexts and not fetched anymore in
1117 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1119 * The local hosts listenning address and port is also resolved
1120 now when starting the server. We want to have the socket object
1121 to include the real address and port for the listener. Added
1122 new function silc_net_check_local_by_sock into the files
1123 lib/silcutil/silcnet.[ch].
1125 * Fixed a broadcast bug in server -> do not broadcast if we
1128 * Fixed a routing bug. Do not route broadcast packets ever.
1129 Broadcast packets must be processed always and not routed since
1130 they may be destined to some other host than yourself and thus
1131 would get routed without no good reason. Affected file is
1134 * Added function silc_server_config_is_primary_route to check
1135 whether primary router connection has been configured (a router
1136 configuration that we are initiating). If there is not, we
1137 will assume that there is only two routers in the SILC network
1138 and we will use the incoming router connection as our primary
1139 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1141 * Changed the order of the broadcasting. Broadcast _after_ the
1142 packet has been processed not before. Affected file is
1145 * Fixed a [ClientConnection] parsing bug. The port was never
1146 parsed correctly thus resulting to port 0. Affected file
1147 silcd/serverconfig.c.
1149 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1150 argument and did not set the broadcast packet flag. Affected
1151 file silcd/packet_send.c. Fixed same bug in the function
1152 silc_server_send_notify as well.
1154 * If we receive NEW_ID packet for our own ID in the server, ignore
1157 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Removed the nickname from the Private Message Payload.
1162 Updated the code and the protocol specs.
1164 * Updated protocol specs for submitting to the IETF.
1166 * Tweaked the Random Number Generator a bit. Affected file
1167 lib/silccrypt/silcrng.c. Exported a new function
1168 silc_rng_[global]_add_noise which can be used to add more
1171 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * Do not parse packets with different timeout when protocol
1174 is active -> may cause problem with rekey. Affected file
1177 * When server receives signoff notify it must not create
1178 new channel key if the client is on any channels since the
1179 sender of the signoff notify will create it.
1181 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1183 * Added printing of error messages during SKE protocol from the
1184 failure packet sent by server during SKE. Affected file
1187 * Removed the client's failure_callback handling with timeout
1188 and handle it immediately when received.
1190 * The SKE library returned wrong type in SUCCESS and FAILURE
1191 packets. They must be 32 bit MSB not 16 bit MSB.
1193 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1195 * Ok, rewrote the logic of the re-key and now it seems to work.
1196 I tested it on high traffic with frequent re-keys without
1197 problems. Added hmac_receive (and renamed hmac to hmac_send)
1198 in SilcClientConnection in lib/silcclient/client.h and
1199 in SilcIDListData in silcd/idlist.h. Also, removed the
1200 SilcPacketParserContext's cipher and hmac fields as they are
1201 not needed anymore and actually caused some problems when
1202 the ciphers and hmac's changed underneath the packet parser.
1204 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1206 * If re-key protocol is active then process the incoming packets
1207 synchronously since we must assure that icoming packets encrypted
1208 with the old key is processed before the new keys is set to
1209 use. This is true other packets than for REKEY packets.
1210 Affected file silcd/server.c. The same was done to client library
1211 as well, affected file lib/silcclient/client.c.
1213 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1215 * Fixed bug in client and server to accept the force send if
1216 the packet is send from silc_[server/client]_packet_process
1217 function. Otherwise the packets are never delivered, oops.
1219 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1221 * Disable force sending of packets when REKEY protocol is active.
1222 We must assure that no packet is sent directly when rekey is
1223 performed. All packets must be sent through packet queue.
1224 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1225 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1226 function is silc_[server/client]_packet_send_real to check
1229 * Replaced the SIM paths from example config files to
1230 /usr/local/modules. Also, make install creates now
1231 /usr/local/silc/logs directory to hold all the SILC server
1234 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1236 * Made the configure.in.pre work on Solaris. Patch by salo.
1238 * Made all ciphers compatible with non-x86 machines. Defined
1239 CBC mode macros into lib/silccrypt/ciphers_def.h.
1241 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1243 * Fixed the make install.
1245 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * When MAC computation fails the silc_packet_decrypt returned 0
1248 even though it was supposed to return -1. Fixed this. The
1249 affected file is lib/silccore/silcpacket.c.
1251 * Do not replace the config files in /etc/silc (in make install)
1252 if they already exist. Affected file ./Makefile.am.
1254 * Do not send re-key packets immediately but through packet queue.
1255 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1257 * Changed silc_net_check_host_by_sock to return FALSE if the
1258 IP/DNS could not be resolved. Though, it returns the IP address
1259 now even if it could not resolve it (but returns also FALSE).
1260 Affected file lib/silcutil/silcnet.[ch].
1262 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1264 * Added silc_pkcs_decode_identifier to decode the public key's
1265 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1266 Added also silc_pkcs_free_identifier. Added also new context
1267 SilcPublicKeyIdentifier.
1269 * Added -S option to the silc client. It is used to dump the
1270 contents of the specified public key file.
1272 * Changed the PKCS api to return the public key length when
1273 setting the public key.
1275 * Fixed a fatal bug in the public and private key file loading.
1276 Affected file lib/silccrypt/silcpkcs.c.
1278 * Execute the packet parsing for client with zero (0) timeout
1279 if the protocol is active. Affected file silcd/server.c.
1281 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1283 * Made the key generation options to the silcd program. Added
1284 -C option, equivalent to client's option.
1286 * Added new [ServerKeys] config section to the server. It
1287 configures the server's public and private key.
1289 * Defined generic Public Key Payload into the protocol
1290 specification to send specific type of public keys and
1293 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1294 public key or certificate.
1296 * Implemented the GETKEY command to the server and to the
1297 client library and on user interface.
1299 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Made preliminary `make install' work.
1303 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1305 * Added SilcServerRekey context into silcd/idlist.h.
1307 * Added the PFS support as defined in the specification to the
1308 SKE protocol. Affected files lib/silcske/*.c.
1310 * Added `ske_group' field to the SilcServerRekey context to hold
1311 the number of the SKE group that is used with PFS in re-key.
1312 Affected file silcd/idlist.h.
1314 * Added PFS re-key support to the server. Affected file is
1317 * Added silc_protocol_cancel to cancel execution of the next
1318 state of the protocol. Affected file is
1319 lib/silccore/silcprotocol.[ch].
1321 * Added the re-key support with and without PFS to the client
1322 library. Re-key is performed once in an hour, by default.
1324 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1325 Added silc_client_rekey_callback and silc_client_rekey_final.
1326 Affected files are lib/silcclient/protocol.[ch] and
1327 lib/silcclient/client.[ch].
1329 * Removed the `hmac_key' and `hmac_key_len' fields from the
1330 SilcClientConnection structure; not needed. Affected file is
1331 lib/silcclient/client.h.
1335 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Do not ask whether user wants to use the negotiated private key
1338 for private messages, just use it. Affected file is
1339 silc/local_command.c.
1341 * Added `send_enc_key' and `enc_key_len' fields to the
1342 SilcIDListData structure since they are needed in the re-key
1343 phase. Affected file is silcd/idlist.[ch].
1345 * Implemented the simple re-key protocol into the server.
1346 Affected files silcd/server.c and silcd/protocol.[ch]. The
1347 re-key will be performed once in an hour, by default.
1349 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1350 Added silc_server_rekey, silc_server_rekey_callback and
1351 silc_server_rekey_final.
1353 * Removed Tunneled flag from the protocol. Updated the code
1354 and the specifications.
1356 * Adde `pfs' field to the SilcIDListData to indicate whether
1357 the PFS is to be performed in the re-key. Affected file is
1360 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1362 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1363 int64 of at least the xintXX size. If void * is less that 4
1364 bytes uint32 * will be used. Defined bool as boolean.
1366 * Changed _ALL_ unsigned long and unsigned int to uint32,
1367 unsgined short to uint16 in the source tree.
1369 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1370 not handle clients that has entry->data.registered == FALSE.
1371 They are not in the network anymore. Affected file is
1374 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1376 * Implemented the sending of the SERVER_SIGNOFF notify in the
1377 server. Affected file is silcd/server.c.
1379 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1380 Added also silc_notify_payload_encode_args into the
1381 lib/silccore/silcnotify.[ch].
1383 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1384 Affected file silcd/packet_receive.c.
1386 * Implemented the SERVER_SIGNOFF notify handling in the client
1387 library. Affected file lib/silcclient/client_notify.c. Also,
1388 implemnted the printing of the SERVER_SIGNOFF info to the
1389 application. Affected file silc/client_ops.c.
1391 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1392 if the deleting was successful. Affected file silcd/idlist.[ch].
1394 * Added support for public key authentication in the connection
1395 authentication protocol in the client library. Affected file
1396 lib/silcclient/protocol.c.
1398 * Changed the server's silc_idlist_get_clients_by_* interface
1399 to support already allocated array so that new entries may be
1400 added to pre-allocated array. Affected file silcd/idlist.[ch].
1401 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1402 and command replies.
1404 * All command reply functions in the server now calls the
1405 pending command callback even if error occured. This way the
1406 error will be delivered to the client as well. Affected files
1407 silcd/command.c and silcd/command_reply.c.
1409 * Fixed INFO command to return local server's info if no server
1410 was provided. Affected file lib/silcclient/command.c.
1412 * Removed RESTART command for good. Updated the code and the
1415 * Rewrote parts of the task system. It is a bit simpler now.
1416 Removed unsued task priorities. The affected files are
1417 lib/silcutil/silctask.[ch].
1419 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1421 * Moved the USERS printing from the library to the application.
1422 Affected files lib/silcclient/command.c and silc/client_ops.c.
1424 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Added channel key re-key support. The re-key is perfomed
1429 only by the router and is done once in an hour. Added `rekey'
1430 field to the SilcChannelEntry in the server. Affected files
1431 silcd/server.c and silcd/idlist.h.
1433 * Added silc_task_unregister_by_context into the file
1434 lib/silcutil/silctask.[ch].
1436 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1438 * Added SILC_UMODE_GONE mode to indicate when the client is not
1439 present in the SILC network. Added also support to the local
1440 command AWAY that will set this mode. Added support of showing
1441 "xxx is gone" in WHOIS command. The USERS command shows the
1442 gone status as well.
1444 * Fixed setting server and router operator privileges in the
1445 server's UMODE command. Affected file silcd/command.c.
1447 * Merged the SKE KE1 and KE2 payloads into one payload. The
1448 new KE payload is equivalent to the old KE2 payload.
1450 Cleaned up the SKE Start Payload parsing. It now uses the
1451 simple buffer unformatting to do the parsing. A lot faster
1454 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1455 to the SKE that is used to indicate whether both of the SKE
1456 parties should perform authentication. By default only the
1457 responder performs authentication. By setting this flag also
1458 the initiator must do authentication. By default it is unset
1459 since in normal SKE case, client to server connection, only
1460 the responder should do authentication. When doing SKE between
1461 two clients both should perform authentication. Updated the
1462 code and the protocol specs.
1464 * A little fix to IDENTIFY command in the server. Search the
1465 client first by hash not nickname. Affected file is
1468 * Fixed the silc_client_close_connection to support closing
1469 the client to client connections wihtout deleting too much
1470 data. Affected file lib/silcclient/client.c.
1472 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1473 are received if protocol used to be active but is not anymore
1474 the application would crash due to NULL pointer dereference.
1475 Affected files silcd/server.c and lib/silcclient/client.c.
1477 * Added `hash' field to the SilcClientConnection to include
1478 the hash function negotiated in the SKE protocol.
1480 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1481 to set the channel founder authentication data. A client can
1482 claim the founder rights later by providing the authentication
1483 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1484 This way the channel founder can regain the channel founder
1485 privileges even it is left the channel. This works only on
1486 local server and the client must be connected to the same
1487 server to be able to regain the founder rights. Updated the
1488 protocol specs accordingly.
1490 Added support to the CMODE command in the client to set the
1491 founder auth data. Read the README to see how to set it.
1493 Added support to the CUMODE command to claim the founder
1494 rights. Read the README to see how to do it.
1496 Added support for the founder authentication to the Channel
1497 Entry in the server. Affected file silcd/idlist.h.
1499 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1500 server's CMODE command. Affected file silcd/command.c.
1502 * Added the following new functions into lib/silccore/silcauth.[ch]:
1503 silc_auth_get_method and silc_auth_get_data.
1505 * The server now saves the remote hosts public key to the
1506 SilcIDListData pointer. Affected file silcd/protocol.c.
1508 * The normal server now does not remove the channel entry from
1509 the cache if the founder authentication data is set. It used
1510 to remove it if the founder was the last one on the channel on
1511 the server and left the channel. The auth data is saved and
1512 if the channel is re-joined later the old entry is used with
1513 the old auth data. Affected files silcd/command_reply.c and
1516 * Removed the `pkcs' field from the SilcIDListData structure
1517 in the server; it is not used. Affected file silcd/idlist.h.
1519 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1521 * Fixed packet processing on slow links. Partial packets were
1522 never re-processed because the incoming data buffer was cleared
1523 by the application. Application must not directly clear the
1524 sock->inbuf, the packet processing routines handle it. Fixed
1525 this in client library and in server.
1527 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1529 * Fixed the WHOIS and IDENTIFY send reply function to really
1530 check whether to send list or just one entry. Affected file
1533 * Cleaned up the LEAVE command's channel key distribution. The
1534 affected file silcd/command.c.
1536 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1537 can enforce the channel mode as well. In that case the ID
1538 includes the ID of the server. The code now enforces the
1539 mode change if the router have different mode than the server.
1541 * The notify client operation with CMODE_CHANGE notify can now
1542 return NULL client_entry pointer if the CMODE was not changed
1543 by client. Application must check for this.
1545 * Added <Server ID> argument to INFO command to support server
1546 info fetching by Server ID.
1548 * Added silc_server_announce_get_channel_users to get assembled
1549 packets of channel users of the specified channel. Affected
1550 file silcd/server.[ch].
1552 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1553 was freed underneath the ID Cache.
1555 * Re-announce clients when the server received CHANNEL_CHANGE
1556 notify from the router. Affected file silcd/packet_send.c.
1558 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1560 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1561 crashed since it did not handle the fact that there is no cipher
1562 called "3" and didn't check the error condition. Now fixed.
1564 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1565 flag. It can be used to send message requests.
1567 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1569 * Implemented the RESTART command in the client.
1571 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1572 notice type messages. Added notice printing to the user
1575 * The channel keys are not re-generated if the channel's mode
1576 is PRIVKEY, ie private key on the channel exists. Affected
1577 files silcd/server.c and silcd/command.c.
1579 * Fixed a little bug in channel message delivery when channel
1580 private keys are set in the server. Affected file is
1581 silcd/packet_send.c.
1583 * Changed the setting on channel->on_channel = TRUE from the
1584 silc_client_save_channel_key to the JOIN command reply. The
1585 key payload is not received if the private channel key is set.
1586 Affected file lib/silcclient/command_reply.c and the
1587 lib/silcclient/client_channel.c.
1589 * When the CMODE_CHANGE notify is sent and the channel private
1590 key mode is removed the channel key must be re-generated in
1591 other cells as well. Added this support for the router in the
1592 silcd/packet_receive.c.
1594 * Added new local command NOTICE to send notice message on
1595 channel. Affected file silc/local_command.[ch].
1597 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1599 * Added new local command ME to the client. It is used to send
1600 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1601 some action. Affected file silc/local_command.[ch].
1603 * Changed channel_message and private_message client operations
1604 to deliver the message flags to the application. Added also
1605 the `flags' arguments to the silc_client_send_channel_message
1606 and silc_client_send_private_message functions. Affected file
1609 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1611 * Redefined the Private Message Payload to support private message
1612 keys and to support the new private message flags. Updated
1613 the protocol specs. Flags makes it possible to have for example
1614 CTCP style messages.
1616 * Added new type SilcPrivateMessagePayload and defined an API
1617 for it in the lib/silcclient/silcprivate.[ch].
1619 * Tested private message private keys successfully. Tested the
1620 private message key set, unset and list commands with the new
1623 * Redefined the Channel Message Payload to include the channel
1624 message flags (equal with private message flags) to support
1625 for example CTCP style messages.
1627 * Defined some of the message (for channel and private message)
1628 flags. Updated the protocol specs and added the flags to the
1629 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1631 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * Added SilcKeyAgreementStatus type to the key agreement routines
1634 to indicate the current status and error if one occured.
1635 The status types are defined in the lib/silcclient/silcapi.h.
1637 * Added new local command KEY that is used to set and unset private
1638 keys for channels, set and unset private keys for private messages
1639 with remote clients and to send key agreement requests and
1640 negotiate the key agreement protocol with remote client. The
1641 key agreement is supported only to negotiate private message keys,
1642 it currently cannot be used to negotiate private keys for channels,
1643 as it is not convenient for that purpose.
1645 * Fixed a minor pending callback setting bug in the function
1646 silc_client_get_client_by_id_resolve, now the function works.
1647 Affected file lib/silcclient/idlist.c.
1649 * Added function silc_net_get_local_port to get local bound
1650 port by socket. Added to lib/silcutil/silcnet.[ch].
1652 * Added `sockets' and `sockets_count' fields to the SilcClient
1653 object. They hold the sockets of the listenning sockets in
1654 the client. Listenning sockets may be for example the key
1655 agreement server. Affected file lib/silcclient/client.[ch].
1656 Added functions the silc_client_add_socket and the
1657 silc_client_del_socket. They are exported to the application
1660 * Added ~./silc/clientkeys to support other client's public keys.
1662 * Renamed verify_server_key client operation to verify_public_key
1663 and added one argument to indicate the type of the connection
1664 (server, client etc.).
1666 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1668 * Added silc_server_connection_auth_request to handle the
1669 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1670 silcd/packet_receive.[ch].
1672 * Added silc_server_send_connection_auth_request into the
1673 silcd/packet_send.c to send the connection auth request packet.
1675 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1678 * Fixed the public key authentication in responder side in the
1679 server. The `auth_data' pointer includes the SilcPublicKey
1680 not the path to the public key. Affected file silcd/protocol.c.
1682 * Implemented the public key authentication in the initiator side
1683 in the server. Affected file silcd/protocol.c.
1685 * Removed the [RedirectClient] config section from the server
1686 configuration. Is not needed and I don't want to implement it.
1688 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1690 * Cleaned up the CMODE command in the server. It now works
1691 correctly and supports all the modes defined in the protocol.
1692 Affected file is silcd/command.c.
1694 * Added `hmac_name' field to the SilcChannelEntry in the server
1695 to hold the default HMAC of the channel. It can be set when
1696 creating the channel (with JOIN command). Affected files
1699 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1700 type to indicate the change of the current cipher and hmac
1701 on the channel. Client can safely ignore the <cipher> argument
1702 (if it chooses to do so) since the CHANNEL_KEY packet will
1703 force the channel key change anyway. The <hmac> argument is
1704 important since the client is responsible of setting the new
1705 HMAC and the hmac key into use.
1707 * Fixed the CMODE command in the client library as well.
1709 * Tested CMODE command in router environment successfully.
1711 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * Show the version of the remote client (or server) when connecting
1714 to the server. It is logged to the log file. Affected file
1715 is silcd/protocol.c.
1717 * Fixed the KILLED notify handling in the client library. The
1718 client must be removed from all channels when receiving the
1721 Also, do not remove the client entry when giving the KILL
1722 command but when the KILLED notify is received.
1724 * Removed silc_idlist_find_client_by_nickname from the server.
1725 Not needed anymore. Affected files silcd/idlist.[ch].
1727 * Implemented the CHANNEL_CHANGE notify type handling to the
1728 server. Affected file silcd/server.c.
1732 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1734 * Added silc_server_send_notify_invite to send the INVITE
1735 notify between routers.
1737 * Implemented the INVITE command correctly to the server.
1739 * Implemented the INVITE notify type handling in the server.
1741 * Implemented the INVITE command to the client library and on the
1744 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1746 * Added function silc_server_get_client_resolve to find the
1747 client entry by ID from all ID lists and then resolve it
1748 (using WHOIS) if it cannot be found. Affected file is
1751 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1753 * Implemented the BAN command to the client library.
1755 * The JOIN command in the server now checks the invite list
1758 * Changed the silc_command_reply_payload_encode_va and the
1759 silc_command_payload_encode_va to support that if argument is
1760 NULL it ignores and checks the next argument. Affected file
1761 lib/silccore/silccommand.c.
1763 * Added silc_server_send_notify_ban to send the BAN notify
1764 type between routers.
1766 * Chaned the silc_notify_payload_encode to support that if
1767 argument is NULL it ignores and checks the next argument.
1768 Affected file lib/silccore/silcnotify.c.
1770 * Tested ban lists in router environment successfully.
1772 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1774 * Implemented BAN command to the server, in silcd/command.[ch].
1776 * Removed the BAN and INVITE_LIST modes from the CMODE command
1779 * Added function silc_string_match to regex match two strings.
1780 Affected files lib/silcutil/silcutil.[ch].
1782 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1784 * Redefined parts of the SilcChannelEntry in the server to support
1785 the new ban and invite lists.
1787 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1789 * Redefined the INVITE command. The same command can be used to
1790 invite individuals to the channel but also to manage the invite
1791 list of the channel (to add to and remove from the invite list).
1792 Updated the protocol specs.
1794 * Added new command SILC_COMMAND_BAN that can be used to manage
1795 the ban list of the channel. Updated the protocol specs.
1797 * Removed the channel modes: the SILC_CMODE_BAN and the
1798 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1799 in the CMODE command. The equivalent features are now available
1800 using INVITE and BAN commands. Updated the protocol specs.
1802 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1803 in the network about change in the current ban list. The notify
1804 type is not used by the client.
1806 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1807 support the invite lists.
1809 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1811 * Added new function silc_string_regexify that converts string
1812 including wildcard characters into regex string that can
1813 be used by the GNU regex library. Added into the file
1814 lib/silcutil/silcutil.[ch].
1816 Added silc_string_regex_combine to combine to regex strings
1817 into one so that they can be used as one regex string by
1818 the GNU regex library. Added into the file
1819 lib/silcutil/silcutil.[ch].
1821 Added silc_string_regex_match to match two strings. It returns
1822 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1824 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1826 * Imported GNU regex to the soruce tree into lib/contrib.
1827 Fixed some compiler warning from the regex.c.
1829 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * Fixed MOTD command in the server to work in router environment.
1833 * Fixed the MOTD command in the client library to support
1834 the server argument in the command.
1836 * Added `nickname_len' argument to the silc_idlist_add_client
1837 in the server, as the `nickname' argument may be binary data
1840 * Added silc_idlist_get_channels to return all channels from
1843 * Implemented LIST command to the server. Affected file is
1846 * Implemented the LIST command to the client library and on the
1849 * Added [<user count>] argument to the LIST command reply.
1850 With private channels the user count is not shown.
1852 * Updated TODO and README.
1854 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * The client entry's data.registered must be TRUE even with
1857 global client entry on global client list. The data.registered
1858 is used to check whether the client is anymore in the network,
1859 for example with WHOWAS command so it must be valid.
1861 * Fixed the WHOWAS command in the server. It now actually works
1862 in router environment. Added function into silcd/command_reply.c
1863 silc_server_command_reply_whowas_save.
1865 * Added silc_idlist_purge function to the silcd/idlist.c
1866 to periodically purge the ID Cache.
1868 * Fixed INFO command in the server. It works now in router
1869 environment. Added <server name> argument to the INFO command
1870 reply. Updated the protocol specs.
1872 * Fixed minor bug in silc_idcache_purge to not purge if the
1873 expire value is zero.
1875 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1876 they were buggy because of the WHOWAS information.
1878 * Fixed local command MSG to handle the async resolving of
1879 the remote client properly. It used to fail the first MSG.
1880 Affected file silc/local_command.c.
1882 * Added `data_len' field to SilcIDCache context.
1884 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1886 * Update TODO. Todo in commands in the server.
1888 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1891 used by routers as broadcast packet to inform other routers
1892 about the changed user mode.
1894 Implemented the notify handling in the server. Affected file is
1895 silcd/packet_receive.c. Added the function
1896 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1898 * Added new generic Channel Payload and deprecated the New Channel
1899 Payload. The New Channel Payload is now the generic Channel
1902 * Added new argument `mode' to the silc_server_send_new_channel
1903 as it is required in the Channel Payload now.
1905 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1906 and created a new and real SilChannelPayload to represent the
1907 new generic Channel Payload. Implemented the encode/decode
1908 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1910 * Added silc_server_get_client_channel_list to return the list
1911 of channels the client has joined for WHOIS command reply.
1912 Affected file silcd/server.[ch].
1914 * Implemented the channel list sending in the WHOIS command reply
1915 in server and in the client.
1917 Implemented the channel list displaying on the user interface
1918 as well. Affected file silc/client_ops.c.
1920 * Added silc_channel_payload_parse_list to parse list of Channel
1921 Payloads. It returns SilcDList list of SilcChannelPayloads.
1922 Client for example can use this function to parse the list of
1923 channels it receives in the WHOIS command reply. The caller
1924 must free the list by calling silc_channel_payload_list_free.
1925 Affected files lib/silccore/silcchannel.[ch].
1927 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1929 * Added one new argument <user mode> to the WHOIS command reply
1930 to return the mode of the user in SILC. Updated the protocol
1933 Implemented it to the server and client.
1935 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1937 * Fixed the mode printing on the user interface on joining.
1938 Affected file silc/client_ops.c.
1940 * Implemented the UMODE command and user modes in general to the
1941 client library and to the user interface.
1943 * Implemented the UMODE command to the server.
1945 * The server now sends UNKNOWN_COMMAND error status if client sends
1946 unknown command. Affected file silcd/command.c.
1948 * All server commands now handle the command identifier the right
1949 way when sending the command reply to the client. The client can
1950 use to identify the command replies with the identifier.
1952 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1954 * Added silc_server_get_client_route to resolve the route to
1955 the client indicated by the client ID. Affected file is
1958 * Added silc_server_relay_packet as general function to relay
1959 packet to arbitrary destination. This deprecates functions
1960 like _send_private_message_key, _relay_notify etc. Affected
1961 file is silcd/packet_send.[ch].
1963 Removed silc_server_send_key_agreement,
1964 silc_server_send_private_message_key and
1965 silc_server_packet_relay_notify functions from the file
1966 silcd/packet_send.[ch].
1970 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1971 server. Affected file silcd/packet_receive.[ch].
1973 * Implemented the KILL command to the client. Implemented the
1974 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1975 Affected files lib/silcclient/command[_reply].c and
1976 lib/silcclient/client_notify.c. Implemented the KILL notify
1977 printing in the user inteface.
1979 * Fixed a lot silc_parse_nick memory leaks from the client
1980 library in the file lib/silcclient/command.c.
1982 * Changed the silc_server_send_notify_on_channels's `sender'
1983 argument from SilcSocketConnection to SilcClientEntry to
1984 check the sender as entry and not as connection object and not
1985 to send to the client provided as argument. The affected file
1986 is silcd/packet_send.[ch].
1988 * The notify packets that are destined directly to the client used
1989 to not to be processed by the server. Now changed that and the
1990 server processes all notify packets. After relaying the packet
1991 to the client the notify packet is processed in the server.
1993 * The silc_server_free_client_data now checks whether there is
1994 pending outgoing traffic for the client and purges the data to
1995 the network before removing the client entry.
1997 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1999 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2000 an client is killed from the SILC Network. Updated the protocol
2003 Added new function silc_server_send_notify_killed to the
2004 silcd/packet_send.[ch].
2006 * Added function silc_server_packet_relay_notify to relay notify
2007 packets that are destined directly to a client. In this case
2008 the server does not process the notify packets but merely relays
2009 it to the client. Affected file silcd/packet_send.[ch].
2011 Added also silc_server_packet_process_relay_notify to check
2012 whereto relay the notify. Affected file is
2013 silcd/packet_receive.[ch].
2015 * Implemented the KILL command to the server.
2019 * Added the backup schema desgined last fall to the protocol
2020 specs for everyone to see. The specification is in the
2021 *-spec-xx.txt draft and the packet type definitions for the
2022 backup routers is in *-pp-xx.txt draft. Thusly, added also
2023 new packet type SILC_PACKET_CELL_ROUTERS.
2025 * A big security problem in the implementation discovered. The
2026 signoff of an client did not cause new channel key generation
2027 which it of course should've done. The channel keys must be
2028 always re-generated when client leaves (or signoffs) the channel.
2029 The silc_server_remove_from_channels funtion now handles
2030 the channel key re-generation.
2032 * Added `sender' argument to the silc_server_send_notify_on_channels
2033 to not to send the client provided as argument. Affected file
2034 silcd/packet_send.[ch].
2036 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Implemented OPER and SILCOPER commands into the server and
2041 * Added silc_auth_verify and silc_auth_verify_data to verify
2042 the authentication directly from the authentication payload.
2043 It supports verifying both passphrase and public key based
2044 authentication. Affected file lib/silccore/silcauth.[ch].
2046 * Added `hash' field to the SilcIDListData structure. It is the
2047 hash negotiated in the SKE protocol. Affected file is
2050 * Slight redesigning of the SilcAuthPayload handling routines.
2051 Do not send SilcPKCS but SilcPublicKey as argument.
2053 * Implemented the public key authentication support to the
2054 serverconfig. The public key is loaded from the provided path
2055 and saved as authentication data to void * pointer. Thus,
2056 changed the unsigned char *auth_data to void *auth_data;
2058 * Fixed SHUTDOWN command to send the reply before the server
2059 is shutdown. :) Affected file silcd/command.c.
2061 * Fixed fatal bug in CONNECT command. The hostname was invalid
2062 memory and server crashed. Affected file silcd/command.c.
2064 * Fixed fatal bug in CLOSE command. The server_entry became
2065 invalid but was referenced later in the command. Affected file
2068 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Fixed fatal bug in failure packet handling. Server ignored
2071 the failure and thus crashed when it came.
2075 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2078 that the command may be executed only once in (about) 2 seconds.
2079 The old SILC_CF_LAG flag is same but allows command bursts up
2080 to five before limiting.
2082 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2083 server code. Various commands now includes the CF_LAG_STRICT
2084 flag to disallow any kind of miss-use of the command.
2086 * Fixed the silc_buffer_unformat to not to allocate any data
2087 if the length of the data is zero. It used to allocate the
2088 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2090 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Changed the format of AdminConnection configuration section
2093 in the server. Added username of the admin to the format.
2094 Affected files silcd/serverconfig.[ch].
2096 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2097 to return admin configuration data by host, username and/or
2100 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2102 * Implemented WHOWAS command to the server. Added the functions:
2104 silc_server_command_whowas_parse,
2105 silc_server_command_whowas_send_reply,
2106 silc_server_command_whowas_from_client and
2107 silc_server_command_whowas_from_server
2109 * Added <Client ID> argument to the WHOWAS command reply. Updated
2110 the protocol specs accordingly.
2112 * Implemented WHOWAS command and command_reply to the client
2115 Implemented the WHOWAS printing on the user interface.
2117 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2119 * Added new argument to the WHOWAS command reply, the real name.
2120 It is an optional argument. Updated the protocol specs.
2122 * Added SilcIDCacheDestructor callback that is registered when
2123 the SilcIDCache is allocated. The callback is called when
2124 an cache entry in the ID Cache expires, or is purged from the
2125 cache. Added into lib/silccore/idcache.[ch].
2127 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2128 to destruct the client entries when the cache entry expires.
2129 Other ID Cache's in server and in the client library ignores
2132 * If the ID Cache entry's `expire' field is zero then the entry
2133 never expires. Added boolean `expire' argument to the
2134 silc_idcache_add function in the lib/silccore/idcache.[ch].
2135 If it is TRUE the default expiry value is used.
2137 * Added silc_server_free_client_data_timeout that is registered
2138 when client disconnects. By default for 5 minutes we preserve
2139 the client entry for history - for WHOWAS command.
2141 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Added support to the server to enforce that commands are not
2144 executed more than once in 2 seconds. If server receives
2145 commands from client more frequently, timeout is registered
2146 to process the commands. Affected file silcd/command.c.
2147 Added new function silc_server_command_process_timeout.
2149 * Changed NICK_NOTIFY handling in client library to check that
2150 if the client's nickname was changed, so there is no need to
2151 resolve anything from the server.
2153 * Removed error printing from the WHOIS and IDENTIFY commands.
2154 If error occurs then it is ignored silently in the client library.
2155 The application, however, may map the received error to
2156 human readable error string. The application currently maps
2157 the NO_SUCH_NICKNAME error to string.
2159 * Made the command status message public to the application. Moved
2160 them from lib/silcclient/command_reply.c to
2161 lib/silcclient/command_reply.h. The application can map the
2162 received command status to the string with the
2163 silc_client_command_status_message function.
2165 * Added check to the server to check that client's ID is same
2166 as the Source ID in the packet the client sent. They must
2169 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2171 * Added dist-bzip hook to the Makefile.am to make bzip2
2172 compressed distributions.
2174 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2176 * Server now enforces the maximum length for the nickname and
2177 the channel as protocol specification dictates. 128 bytes for
2178 nickname and 256 bytes for channel name.
2180 * Moved the WHOIS printing to the application. The client libary
2181 does not print out the WHOIS information anymore, the application
2182 must do it. Renamed silc_client_command_reply_whois_print to
2183 the silc_client_command_reply_whois_save.
2185 The client's idle time is also sent to the application now, and
2186 the idle is shown on screen.
2188 * Added silc_client_command_reply_identify_save to save the
2189 received IDENTIFY entries.
2191 * Do not check for channel private keys in message sending and
2192 reception if the channel does not have the PRIVKEY mode set.
2193 Affected file lib/silclient/client_channel.c.
2195 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2198 just surfaced after chaning the JOIN procedure.
2200 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Added silc_client_get_clients_by_list to get client entries
2203 from Client ID list, that is returned for example by JOIN
2204 and USERS command replies. The application should use this
2205 function for example when JOIN command reply is received to
2206 resolve the clients already on the channel (library does not
2207 do that anymore as USERS command reply is not used in the JOIN
2208 procedure anymore). Affected files lib/silcclient/silcapi.h and
2209 lib/silcclient/idlist.c.
2211 * JOIN command reply and USERS command reply returns now SilcBuffer
2212 pointers instead of unsigned char pointers when returning
2213 the client list and mode list.
2215 * Added <Client ID> argument to the JOIN command reply, mainly
2216 for the server to identify for which client the command was
2217 originally sent. Updated protocol specs accordingly.
2219 * Added SilcDlist private_key pointer to the SilcChannelEntry
2220 in the client to support the channel private keys. Affected
2221 file is lib/silcclient/idlist.h.
2223 * Added SilcChannelPrivateKey argument to the function
2224 silc_client_send_channel_message so that application can choose
2225 to use specific private ke if it wants to. If it is not provided,
2226 the normal channel key is used, unless private keys are set.
2227 In this case the first (key that was added first) is used
2228 as the encryption key.
2230 * Implemented the support for channel private key handling.
2231 Implemented the following functions:
2233 silc_client_add_channel_private_key,
2234 silc_client_del_channel_private_keys,
2235 silc_client_del_channel_private_key,
2236 silc_client_list_channel_private_keys and
2237 silc_client_free_channel_private_keys
2239 Affected file lib/silcclient/client_channel.c.
2241 * Added the support for the private keys in the channel message
2242 sending and encryption and in the message reception and
2243 decryption. Affected funtions are
2244 silc_client_send_channel_message and silc_client_channel_message.
2246 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2248 * Added SKE's key verify callback to the client library's
2249 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2251 * Removed the statement that server (or router) must send USERS
2252 command reply when joining to the channel so that the client
2253 knows who are on the channel. Instead, the client list and
2254 client's mode list is now sent in the JOIN command reply to the
2255 client who joined channel. This is better solution.
2257 * Added function silc_server_get_users_on_channel and function
2258 silc_server_save_users_on_channel to the silcd/server.[ch].
2260 * Removed function silc_server_command_send_users from the
2263 * Do not show topic on the client library anymore. The topic is
2264 sent in the command reply notify to the application and the
2265 application must show the topic now.
2267 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2269 * Added client searching by nickname hash into the IDENTIFY and
2270 WHOIS commands in the server as they were clearly missing from
2271 them. Affected file is silcd/command.c.
2273 * Fixed a bug in private message receiving in the client library.
2274 The remote ID was freed and it wasn't supposed, now it is
2277 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * Minor fix to the channel payload; allocate the data area, as it
2280 needs to be of specific length.
2282 * If the key agreement port is zero then the operating
2283 system will define the bound port. Affected files are
2284 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2286 * Added new function silc_channel_payload_decrypt into the file
2287 lib/silccore/silcchannel.[ch].
2289 * Moved the channel message etc, check from silc_packet_decrypt
2290 to applications. The library calls now a generic
2291 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2292 when the packet is either normal or special. This was done to
2293 allow more wide range of checking that was not allowed when
2294 the code was in library. Now applications can do virtually any
2295 checks to the packet and return to the library the decision how
2296 the packet should be processed. Affected files are
2297 lib/silccore/silcpacket.[ch].
2299 Added silc_server_packet_decrypt_check to the server and
2300 silc_client_packet_decrypt_check to the client library.
2302 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2303 to send with specified source and destination information.
2305 * Channel message delivery between routers was broken after the
2306 channel key distribution was fixed earlier. The channel key
2307 was used be to distributed to other routers as well which is not
2308 allowed by the protocol. Now this is fixed and channel keys
2309 really are cell specific and the channel message delivery between
2310 routers comply with the protocol specification.
2312 * Fixed various commands in server to check also the global list
2313 for the channel entry and not just the local list. The affected
2314 file silcd/command.c.
2316 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * Added assert()s to buffer formatting and unformatting routines
2319 to assert (if --enable-debug) when error occurs. Affected
2320 file: lib/silcutil/silcbuffmt.c.
2322 * Changed to auto-reconnect to check whether the remote host is
2323 router and register the re-connect timeout if it is. It used
2324 to check that whether we are normal server, but router must do
2325 auto-reconnect with another router as well. Affected file
2328 * Removed the [<key len>] option from CMODE command as the cipher
2329 name decides the key length, nowadays. See the defined ciphers
2330 from the protocol specification.
2332 * Added [<hmac>] option to the CMODE command to define the HMAC
2333 for the channel. Added SILC_CMODE_HMAC channel mode.
2335 * Added [<hmac>] option for the JOIN command so that user can
2336 select which HMAC is used to compute the MACs of the channel
2339 * Added Hmac field to the Channel Message Payload. The integrity
2340 of plaintext channel messages are now protected by computing
2341 MAC of the message and attaching the MAC to the payload. The
2342 MAC is encrypted. Now, it is clear that this causes some
2343 overhead to the size of the packet but rationale for this is that
2344 now the receiver can verify whether the channel message decrypted
2345 correctly and also when private keys are set for the channel the
2346 receiver can decrypt the packet with several keys and check from
2347 the MAC which key decrypted the message correctly.
2349 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2350 lib/silccrypt/silccipher.[ch].
2352 * Added silc_hash_len to return the digest length into the
2353 lib/silcrypt/silchash.[ch].
2355 * Rewrote parts of Silc Channel Payload interface in the
2356 lib/silccore/silcchannel.[ch]. The encode function now also
2357 encrypts the packet and parse function decrypts it.
2359 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * Fixed a minor formatting bug in the SKE's key material processing.
2362 It actually might have processed the keys wrong way resulting
2365 * Redefined the mandatory HMAC algorithms and added new algorithms.
2366 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2367 and hmac-md5 truncated to 96 bits. The mandatory is now
2368 hmac-sha1-96. Rest are optional (including the one that used
2369 to be mandatory). Rationale for this is that the truncated HMAC
2370 length is sufficient from security point of view and can actually
2371 make the attack against the HMAC harder. Also, the truncated
2372 HMAC causes less overhead to the packets. See the RFC2104 for
2375 * Added new [hmac] configuration section. The SKE used to use
2376 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2377 is of course wrong. The official names that must be proposed in
2378 the SKE are the ones defined in the protocol specification
2379 (hmac-sha1-96 for example). The user can configure any hmac
2380 using any hash function configured in the [hash] section. At
2381 least, the mandatory must be configured.
2383 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2385 * Added HMAC list to the SKE proposal list. It has now both
2386 hash algorithm list and HMAC list. This makes the protocol
2387 incompatible with previous versions. The SKE now seems to work
2388 the way it is supposed to work, for the first time actually.
2390 * Defined plain Hash algorithms to the protocol specification.
2393 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Implemented support for key agreement packets into the server.
2396 Added functions silc_server_key_agreement and
2397 silc_server_send_key_agreement. Other than these functions,
2398 server has nothing to do with this packet.
2400 * Added support for private message key packets into the server.
2401 Added functions silc_server_private_message_key and
2402 silc_server_send_private_message_key.
2406 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2407 called in the protocol's final callback instead in the END
2408 protocol state. This makes a little more sense and in the same
2409 time in client we can use the same protocol routines for normal
2410 key exchange and to key agreement packet handling as well.
2412 * Added to both client's and server's KE protocol context the
2413 SilcSKEKeyMaterial pointer to save the key material. We will
2414 bring the key material to the protocol's final callback by doing
2415 this. The final callback must free the key material.
2417 * Added SKE's packet_send callback into client's KE protocol
2418 context so that the caller can choose what packet sending function
2419 is used. This way we can use different packet sending when
2420 doing normal SKE when doing key agreement packet handling (in
2421 the key agreement packet handling we do not want to encrypt
2424 * Implemented the responder side of the key agreement routines
2425 in the client. The client can now bind to specified port and
2426 accept incoming key negotiation. The key material is passed
2427 to the application after the protocol is over.
2429 * Implemented the processing of incoming Key Agreement packet
2430 in the client. Added function silc_client_key_agreement to
2433 * Implemented the intiator side of the key agreement routines
2434 in the client. The client can now initiate key agreement with
2435 another remote client. The key material is passed to the
2436 application after the protocol is over.
2438 * Created client_keyagr.c to include all the key agreement
2441 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2442 SILC_TASK_CALLBACK except that it is not static.
2444 * Created client_notify.c and moved the Notify packet handling
2445 from the client.[ch] into that file.
2447 * Created client_prvmsg.c and moved all private message and
2448 private message key routines from the client.[ch] into that file.
2450 * Create client_channel.c and moved all channel message and
2451 channel private key routines from the client.[ch] into that file.
2453 * Changed silc_client_get_client_by_id_resolve to resolve with
2454 WHOIS command instead of IDENTIFY command, in the file
2455 lib/silclient/idlist.c.
2457 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2459 * Implemented the SKE's responder side to the Client library.
2461 * When FAILURE is received to the protocol do not trust it
2462 blindly. Register a timeout to wait whether the remote closes
2463 the connection as it should do it, only after that process the
2464 actual failure. This was changed to both client and server.
2466 * Added client_internal.h to include some of the structures
2467 there instead of client.h in lib/silcclient/.
2469 * Added function silc_task_unregister_by_callback to unregister
2470 timeouts by the callback function.
2472 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2474 * Some "Incomplete WHOIS info" errors has been appearing on the
2475 log files. Took away the entry->userinfo check from WHOIS
2476 reply sending. The entry->userinfo is now " " if client did not
2477 provide one. I thought this was fixed earlier but something
2478 is wrong still. Let's see if the error still appears.
2480 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2482 * Fixed a minor bug in the login when the channel key is
2483 re-generated in the server. It used to generate the key in
2484 wrong order and thus caused problems in the channel traffic.
2486 * Fixed a minor bug in channel key distsribution after
2487 KICK command. The key was not sent to the router even though
2490 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2492 * Added silc_ske_process_key_material_data as generic routine
2493 to process any key material as the SILC protocol dictates. The
2494 function is used by the actual SKE library but can be used by
2495 applications as well. This relates to the private message keys
2496 and the channel private keys since they must be processed the
2497 same way the normal SILC session keys. The protocol dictates
2498 this. Affected files: lib/silcske/silcske.[ch].
2500 Added also silc_ske_free_key_material to free the
2501 SilcSKEKeyMaterial structure.
2503 * Defined silc_cipher_set_key function to set the key for
2504 cipher without using the object's method function. The affected
2505 files: lib/silccrypt/silccipher.[ch].
2507 * Implemented silc silc_client_add_private_message_key,
2508 silc_client_add_private_message_key_ske,
2509 silc_client_del_private_message_key,
2510 silc_client_list_private_message_keys and
2511 silc_client_free_private_message_keys functions in the
2514 Added functions silc_client_send_private_message_key to send
2515 the Private Message Key payload and silc_client_private_message_key
2516 to handle incoming Private Message Key payload.
2518 * Added Cipher field to the Private Message Key payload to set
2519 the cipher to be used. If ignored, the default cipher defined
2520 in the SILC protocol (aes-256-cbc) is used.
2522 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Removed lib/silcclient/ops.h file.
2526 Redefined parts of the SILC Client Library API. Created new
2527 file silcapi.h that deprecates the ops.h file and defines the
2528 published Client Library API. Defined also private message key
2529 API and channel private key API into the file.
2531 This is the file that the application must include from the
2532 SILC Client Library. Other files need not be included by
2533 the application anymore.
2535 * Added new key_agreement client operation callback and also
2536 defined the Key Agreement library API for the application.
2538 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2540 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2541 is used by clients to request key negotiation between another
2542 client in the SILC network. If the negotiation is started it
2543 is performed using the SKE protocol. The result of the
2544 negotiation, the secret key material, can be used for example
2545 as private message key.
2547 Implemented the Key Agreement payload into the files
2548 lib/silccore/silauth.[ch].
2550 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Redefined ciphers for the SILC protocol. Added some new ciphers
2553 and defined the key lengths for the algorithms. Changed the
2554 code accordingly. The default key length is now 256 bits.
2556 * Fixed SKE key distribution function silc_ske_process_key_material
2557 when the key length is more than 128 bits. The default key
2558 length in SILC is now 256 bits.
2560 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2561 to indicate unsupported algorithm.
2563 * Renamed rijndael.c to aes.c and all functions as well.
2565 * Fixed a long standing channel key setting bug in client library.
2566 Weird that it has never surfaced before.
2568 * Fixed bug in channel deletion. If the entire channel is removed
2569 then it must also delete the references of the channel entry
2570 from the client's channel list as the client's channel entry and
2571 the channel's client entry share same memory.
2573 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2575 * Implemented CONNECT and SHUTDOWN commands in the client.
2577 * Implemented CLOSE command to the client.
2579 * Added the function silc_idlist_find_server_by_name into the
2580 files silcd/idlist.[ch].
2582 Added the function silc_idlist_find_server_by_conn into the
2583 files silcd/idlist.[ch].
2585 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * DIE command was renamed to SHUTDOWN. Updated the both code
2590 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2591 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2593 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2596 * Added function silc_server_create_connection function to create
2597 connection to remote router. My server implementation actually
2598 does not allow router to connect to normal server (it expects
2599 that normal server always initiates the connection to the router)
2600 so the CONNECT command is only good for connecting to another
2603 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2606 or some other client was kicked from the channel.
2608 Implemented the handling of the notify type to both client
2611 Implemented silc_server_send_notify_kicked to send the KICKED
2612 notify. It is used to send it to the server's primary router.
2614 * Implemented the KICK command into server and client.
2616 * Added `query' argument to the silc_idlist_get_client function
2617 to indicate whether to query the client from server or not if
2620 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2621 to indicate that the client is not channel founder.
2625 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Removed the rng context from SilcPacketContext structure and
2628 changed that the packet routine uses the Global RNG API.
2630 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Added support for quit message that client can "leave" on the
2633 channel when it quits the SILC. It is ditributed inside the
2634 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2636 Added silc_server_free_client_data that will take the
2637 signoff message as argument.
2639 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2641 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * Updated parts of the protocol specification to keep it up
2646 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2649 payloads in one packet.
2651 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2652 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2653 use now the new List flag.
2655 * Also deprecated the following packet types: REPLACE_ID,
2656 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2658 * Added list support for Notify packet in server.
2660 * Added silc_server_send_notify_channel_change to send the
2661 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2662 the silc_server_send_replace_id.
2664 * Added silc_server_send_notify_nick_change to send the
2665 NICK_CHANGE notify type. Deprecates the function
2666 silc_server_send_replace_id.
2668 * Added silc_server_send_notify_join to send the JOIN notify type.
2669 Deprecates the function silc_server_send_new_channel_user.
2671 * Added silc_server_send_notify_leave to send LEAVE notify type.
2672 Deprecates the function silc_server_send_remove_channel_user.
2674 * Added silc_server_send_notify_cmode and
2675 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2676 types. Deprecates the silc_server_send_set_mode function.
2678 * Added SERVER_SIGNOFF notify type to indicate that server has
2679 quit. This means that all clients on the channel from that
2680 server will drop. This can be also used when netsplit happens.
2682 Deprecated REMOVE_ID packet type since it is not needed anymore
2685 Added silc_server_send_notify_server_signoff to send the
2686 SERVER_SIGNOFF notify type. Deprecates the function
2687 silc_server_send_remove_id.
2689 Added also silc_server_send_notify_signoff to send the
2690 SIGNOFF notify type.
2692 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2693 SILC protocol from this day on. Changed the protocol
2694 specification as well.
2696 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2697 notify type. It is used between routers to notify about
2698 topic changes on a channel.
2700 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2703 * Partly updated the protocol specification to comply with the
2704 changes now made. It is still though a bit outdated.
2706 * The JOIN notify type now takes one extra argument <Channel ID>.
2707 The packet used to be destined to the channel but now the
2708 JOIN type may be sent as list thus it is impossible to
2709 destine it to any specific channel. By adding this argument
2710 it is again possible.
2712 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2714 * Added CREDITS file. The CHANGES and CREDITS file will appear
2715 in the distribution as well.
2717 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2720 types in the server's silcd/packet_receive.c.
2722 * Implemented CMODE and CUMODE to work in router environment.
2724 * Fixed minor encoding and decoding buglet from the
2725 lib/silccore/silcmode.c.
2727 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2730 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2732 * Changed all SilcConfigServer* and silc_config_server* to
2733 SilcServerConfig* and silc_server_config*, respectively.
2736 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2738 * Associated the ID (client or server ID) to the Authentication
2739 Payload to avoid any possibility of forging. Updated the
2740 protocol specification and the code accordingly.
2742 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * The RSA key length is now save to the RsaKey context in the
2745 key generation process in lib/silccrypt/rsa.c. The key length
2746 is now used to figure out the maximum size of the block allowed
2747 to be encrypted/signed.
2749 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2750 is equivalent to the silc_mp_mp2bin but does not allocate any
2753 * Changed silc_mp_mp2bin API to take length argument. If it is
2754 non-zero then the buffer is allocated that large. If zero, then
2755 the size is approximated using silc_mp_sizeinbase, which however
2758 * Created Global RNG API which is global RNG that application can
2759 initialize. After initializing, any routine anywhere in the
2760 code (including library) can use RNG without allocating a new
2761 RNG object. This was done to allow this sort of use of the
2762 RNG in code that has no chance to allocate RNG object. All
2763 applications currently allocate this and many routines in the
2764 library use this. Affected file lib/silccrypt/silcrng.[ch].
2766 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2767 it to use the Global RNG API.
2769 * Defined Authentication Payload into protocol specification that
2770 is used during SILC session to authenticate entities. It is
2771 used for example by client to authenticate itself to the server
2772 to obtain server operator privileges.
2774 Implemented this payload into the lib/silccore/silcauth.[ch].
2775 Implemented also routines for public key based authentication
2776 as the new protocol specification dictates.
2778 Moved definitions of different authentication methods from
2779 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2781 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2782 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2783 silc_pkcs_verify_with_hash functions into the file
2784 lib/silccrypt/silcpkcs.[ch].
2786 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2788 * The client entry's userinfo pointer must be always valid.
2789 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2790 will fail since it requires the userinfo. Now, the userinfo
2791 is allocated as "" if actual userinfo does not exist. Actually,
2792 it must exist and it is totally Ok to drop client connections
2793 that does not announce the userinfo. However, we will make
2794 this workaround for now.
2796 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2797 to return the remote port by socket.
2799 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2802 SILC_SERVER_PENDING_EXEC and added an new macro
2803 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2804 data or when error occurs while processing the pending command.
2806 Added new argument `destructor' into silc_server_command_pending
2807 and to the SilcServerCommandPending object. This destructor is
2808 now called after calling the pending callback or if error occurs
2809 immediately. If error occurs the actual pending callback won't
2810 be called at all - only the destructor. The destructor may be
2811 NULL if destructor is not needed.
2813 All this applies for client library code as well. Similar
2814 changes were made there as well for the pending commands.
2816 In the client, the application must now allocate the
2817 SilcClientCommandContext with the silc_client_command_alloc
2820 * Added reference counter to the SilcServerCommandContext. Added
2821 function silc_server_command_alloc and silc_server_command_dup
2824 Same type of functions added to the client library for the same
2827 * Removed the cmd_ident from IDListData away since it is now
2828 global for all connections. It is the command identifier used
2829 in command sending and with pending commands. The affected file
2832 * Added reference counter to the SilcSocketConnection objecet to
2833 indicate the usage count of the object. The object won't be
2834 freed untill the reference counter hits zero. Currently only
2835 server uses this, and client ignores it. The client must be
2836 set to use this too later. The affected files are
2837 lib/silccore/silcsockconn.[ch]. Added also the function
2838 silc_socket_dup to increase the reference counter.
2840 This was mainly added because it is possible that the socket
2841 is removed underneath of pending command or other async
2842 operation. Now it won't be free'd and proper DISCONNECTING
2843 flags, etc. can be set to avoid sending data to connection that
2844 is not valid anymore.
2846 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2847 the connection. After that it sets SILC_SET_DISCONNECTED.
2848 It is, however, possible that the socket data is not still freed.
2849 The silc_server_packet_process now checks that data is not
2850 read or written to connection that is DISCONNECTED. The socket
2851 get's freed when the reference counter hits zero.
2853 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Changed the client operation API: channel_message operation's
2856 `sender' is now the client entry of the sender, not the nickname
2857 and the `channel' is the channel entry, not the channel name.
2859 In the private_message operation the `sender' is now also the
2860 client entry of the sender not the nickname.
2862 Affected file is lib/silcclient/ops.h and all applications
2863 using the client operations.
2865 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Moved the calling of ops->connect() from connect_to_server_final
2868 into receive_new_id functin since that is the point when the
2869 client is actually allowed to send traffic to network. The
2870 affected file is lib/silcclient/client.c.
2872 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2875 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2876 (if needs broadcasting) instead of broadcasting the packets one
2877 by one which would make a burst in the network traffic.
2879 * Added `broadcast' argument to the functions in silcd/server.[ch]
2880 silc_server_create_new_channel[_with_id] to indicate whether
2881 to send New Channel packet to primary router.
2883 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2885 * Added new function into the silcd/server.[ch] files:
2886 silc_server_create_new_channel_with_id to create new channel with
2887 already existing Channel ID.
2889 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2890 lib/silccore/silcpacket.h. This packet is used t send list of
2891 Set Mode payloads inside one packet. Server uses this to set
2892 the modes for the channels and clients on those channels, that it
2893 announced to the router when it connected to it. The protocol
2894 specification has been updated accordingly.
2896 * The silc_server_new_channel did not handle the packet coming
2897 from normal server as it normally does not send that. However,
2898 when it announces its channels it does send it. Implemented
2899 the support for that.
2901 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2902 into the file lib/silccore/id.h.
2904 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2906 * Fixed memory leaks in the functions silc_idlist_del_client,
2907 silc_idlist_del_channel and silc_idlist_del_server in the file
2908 silcd/idlist.c. All of those leaked like a sieve.
2910 * Fixed some small memory leaks in the client's function
2911 silc_client_notify_by_server.
2913 * Added functions into silcd/server.c: silc_server_announce_clients,
2914 silc_server_announce_channels and silc_server_announce_server.
2915 These functions are used by normal and router server to announce
2916 to its primary router about clients, channels and servers (when
2917 router) that we own. This is done after we've connected to the
2920 These functions effectively implements the following packet types:
2921 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2922 and SILC_PACKET_NEW_ID_LIST.
2924 * Added new functions into the silcd/packet_receive.[ch]:
2925 silc_server_new_id_list, silc_server_new_channel_list and
2926 silc_server_new_channel_user_list to handle the incoming
2927 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2929 * Added support of changing Channel ID in the function
2930 silc_server_replace_id. If the server that announces a channel
2931 to the router already exists in the router (with same name but
2932 with different Channel ID), router is responsible to send
2933 Replace ID packet to the server and force the server to change
2934 the Channel ID to the one router has.
2936 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2937 client that the Channel ID has been changed by the router. The
2938 normal server sends this to the client. Client must start using
2939 the new Channel ID as the channel's ID.
2941 Implemented handling of this new type into lib/silcclient/client.c
2942 into the function silc_client_notify_by_server.
2944 * Added new function silc_idlist_replace_channel_id into the files
2945 silcd/idlist.[ch] to replace the Channel ID.
2947 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Call silc_server_command_identify_check always when processing
2950 the IDENTIFY command in silcd/command.c
2952 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2954 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2955 send keepalive packets. The packet can be sent by clients,
2956 servers and routers.
2958 Added function silc_socket_set_heartbeat into the file
2959 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2960 If not set, the heartbeat is not performed. The actual
2961 heartbeat is implemented in the low level socket connection
2962 library. However, application is responsible of actually
2965 Added silc_server_send_heartbeat to send the actual heartbeat
2966 packet into silcd/packet_send.[ch]. Server now performs
2967 keepalive with all connections.
2969 * Added silc_task_get_first function into lib/silcutil/silctask.c
2970 to return the timeout task with shortest timeout. There was a bug
2971 in task unregistration that caused problems. TODO has been
2972 updated to include that task system must be rewritten.
2974 * The client library will now resolve the client information when
2975 receiving JOIN notify from server for client that we know but
2976 have incomplete information.
2978 * Rewrote parts of silc_server_remove_from_channels and
2979 silc_server_remove_from_one_channel as they did not remove the
2980 channel in some circumstances even though they should've.
2982 * Encryption problem encountered in server:
2984 The LEAVE command used to send the Channel Key packet to the
2985 router immediately after generating it. However, the code
2986 had earlier sent Remove Channel user packet but not immediately,
2987 ie. it was put to queue. The order of packets in the router
2988 was that Channel Key packet was first and Remove Channel User
2989 packet was second, even though they were encrypted in the
2990 reverse order. For this reason, MAC check failed. Now, this
2991 is fixed by not sending the Channel Key packet immediately but
2992 putting it to queue. However, this is more fundamental problem:
2993 packets that are in queue should actually not be encrypted
2994 because packets that are sent immediately gets encrypted
2995 actually with wrong IV (and thus MAC check fails). So, packets
2996 that are in queue should be encrypted when they are sent to
2997 the wire and not when they put to the queue.
2999 However, the problem is that the current system has not been
3000 designed to work that way. Instead, the packet is encrypted
3001 as soon as possible and left to the queue. The queue is then
3002 just purged into wire. There won't be any fixes for this
3003 any time soon. So, the current semantic for packet sending
3006 o If you send packet to remote host and do not force the send
3007 (the packet will be in queue) then all subsequent packets to the
3008 same remote host must also be put to the queue. Only after the
3009 queue has been purged is it safe again to force the packet
3012 o If you send all packets immediately then it safe to send
3013 any of subsequent packets through the queue, however, after
3014 the first packet is put to queue then any subsequent packets
3015 must also be put to the queue.
3017 Follow these rules and everything works fine.
3019 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Added new function silc_server_remove_clients_by_server to
3022 remove all client entries from ID list when the server connection
3023 is lost. In this case it is also important to invalidate all
3024 client entires as they hold the invalid server entry. This
3025 fixes fatal bug when server has lost connection and will reconnect
3028 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Made some sanity checks to silc_server_daemonise like to check
3031 whether the requested user and group actually exists.
3033 * Added sanity check to SKE's silc_ske_responder_finish to check
3034 that the public and private key actually is valid.
3036 * Invalidate the client's nickname when receiving Replace ID
3037 packet and the Client ID is being replaced. This means that the
3038 server will query the nickname if someone needs it (client)
3041 * Sort the ID Cache in client library when the ID Cache data
3042 has changed (needs sorting).
3044 * Do not allow for SILC client to create several connections to
3045 several servers. The client does not support windows right now
3046 and generating multiple connections causes weird behaviour.
3048 Irssi-silc client does support windows and can handle several
3049 connections without problems, see: www.irssi.org and SILC plugin.
3051 * Fixed some places where client was added to the IDList. The
3052 rule of thumb is following (in order to get everything right):
3053 If the client is directly connected local client then the
3054 `connection' argument must be set and `router' argument must be
3055 NULL to silc_idlist_add_client function. If the client is not
3056 directly connected client then the `router' argument must
3057 bet set and the `connection' argument must be NULL to the
3058 silc_idlist_add_client function.
3060 * The funtion silc_server_packet_send_local_channel actually did
3061 not check whether the client was locally connected or not. It
3062 does that now. Fixed a bug related to LEAVE command.
3064 * Fixed Remove Channel User payload parsing bug in server's
3065 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3067 * The server's silc_server_save_channel_key now checks also the
3068 global ID list for the channel as it might not be in the local
3069 list. Fixed a bug related to LEAVE command.
3071 * Is this the end of the [<unknown>] buglet that has been lurking
3072 around for a long time? A little for loop fix in server's
3073 silc_server_command_whois_parse that is used by both IDENTIFY
3074 and WHOIS command. At least, this was a clear bug and a cause
3075 of one type of [<unknown>] buglet.
3077 * WHOIS and IDENTIFY commands call the function
3078 silc_server_command_[whois/identify]_check function even if
3079 we are not router server.
3081 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Added --with-gmp configuration option. If set the GMP
3084 is always compiled in the SILC source tree. If not set then
3085 it is checked whether the system has the GMP3 installed. If
3086 it has then the GMP won't be compiled (the system's headers
3087 and library is used), if it doesn't have it then the GMP is
3088 compiled in the SILC source tree.
3090 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Changed RSA private exponent generation to what PKCS #1
3093 suggests. We try to find the smallest possible d by doing
3094 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3095 not security fix but optimization.
3097 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3099 * Added new config entry [Identity] to fork the server and run
3100 it as specific user and group. A patch from Bostik.
3102 * Imported Dotconf configuration library into lib/dotconf.
3103 This will be used to create the SILC configuration files later.
3104 It will appear in the distsribution after this commit.
3106 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * A big code auditing weekend happening. Auditing code for
3109 obvious mistakes, bugs and errors. Also, removing any code
3112 Removed files for being obsolete:
3114 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3115 inline in the file lib/silcutil/silcbuffer.h)
3117 o lib/silcutil/silcbufutil.c (the header has inline versions)
3119 Changed code to fix possible error conditions:
3121 o The buffer formatting routines now check that the destination
3122 buffer really has enough space to add the data. This applies for
3123 both buffer formatting and unformatting
3124 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3125 unformatting was changed to accomodate following rules:
3126 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3127 sent to the function while XXX_*STRING will not allocate or copy
3128 the data into the buffer. Instead it sets the pointer from the
3129 buffer into the pointer sent as argument (XXX_*STRING used to
3130 require that the pointer must be allocated already). This change
3131 makes this whole thing a bit more consistent and more optimized
3132 (note that the data returned in the unformatting with XXX_*STRING
3133 must not be freed now). The routines return now -1 on error.
3135 o Tried to find all code that use buffer_format and buffer_unformat
3136 and added return value checking to prevent formatting and
3137 especially unformatting errors and possible subsequent fatal
3140 o Changed ske->x and ske->KEY to mallocated pointers in
3141 lib/silcske/silcske.h. Fixed possible data and memory leak.
3143 o Added return value checking to all *_parse* functions. Fixed
3144 many memory leaks as well.
3146 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3147 so that buffer overflows would not happen. All code now also
3148 checks the return value as it can fail.
3150 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Added reconnection support to server if the normal server looses
3153 its connection to the router (for example if router is rebooted).
3154 The server performs normal reconnection strategy implemented
3155 to the server. Affected file silcd/server.c.
3157 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3159 * Added new packet type SILC_PACKET_SET_MODE that is used to
3160 distribute the information about changed modes (for clients,
3161 channels and clients channel modes) to all routers in the
3162 network. Updated the protocol specification accordingly.
3164 Added functions into silcd/packet_send.c and
3165 silcd/packet_receive.c: silc_server_send_set_mode,
3166 silc_server_set_mode.
3168 Added new files silcmode.[ch] into lib/silccore that implements
3169 the encoding and decoding of Set Mode Payload. Added new type
3170 SilcSetModePayload. Moved the definitions of different modes
3171 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3173 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3175 * Oops, a little mistake in server's connection authentication
3176 protocol. The protocol is not ended with FAILURE but with
3177 SUCCESS if the authentication is Ok. :) Affected file is
3180 * Implemented NICK_CHANGE notify handling in server in the file
3181 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3182 the local clients on the channel. After the changing nickname
3183 in router environment snhould work and the [<unknown>] nickname
3184 should appear no more.
3186 The silc_server_replace_id function that receives the Replace ID
3187 payload now sends the NICK_CHANGE notify type also in the file
3188 silcd/packet_receive.c
3190 * Changed WHOIS and IDENTIFY command to support the maximum amount
3191 of arguments defined in protocol specs (3328 arguments). This
3192 fixed a bug that caused problems when there were more than three
3195 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * Added extra parameter, command identifier, to the
3198 silc_client_send_command so that explicit command identifier
3201 Changed that ID list routines uses specific command identifier
3202 when sending WHOIS/IDENTIFY requests to the server so that they
3203 can be identified when the reply comes back.
3205 Affected files lib/silcclient/command.[ch],
3206 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3208 * Added `sender' argument to silc_server_packet_send_to_channel
3209 to indicaet the sender who originally sent the packet to us
3210 that we are now re-sending. Ignored if NULL. Affected file
3211 silcd/packet_send.[ch].
3213 * Added some server statistics support in silcd/server_internal.h
3214 SilcServerStatistics structure and around the server code. Also
3215 send some nice statistics information when client is connecting
3218 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3220 * Fixed channel ID decoding in server's JOIN command reply in
3221 silcd/command_reply.c
3223 * Fixed braodcasting of replace ID payload to not to send it if
3224 we are standalone server in silcd/packet_receive.c.
3226 * Fixed all channel message sending routines to not to send
3227 packets to clients that has router set, since they are routed
3228 separately in the same function earlier. Affects file
3229 silcd/packet_send.c and all channel packet sending functions.
3231 * In USERS reply, res_argv[i] are not allocated, the table
3232 is allocated. Thus changed that free the table, not its
3235 * In server's whois_check and identify_check if the client is
3236 locally connected do not send any WHOIS commands - they are not
3239 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Fixed some minor bugs in client when sending WHOIS command. The
3242 arguments was in wrong order.
3244 * Removed statis function add_to_channel from server in
3245 silcd/command.c that was previously used with the joining but
3248 * Tested USERS command in router environment successfully with two
3249 routers, two servers and two clients.
3251 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Reorganized the USERS command and command reply in client library
3254 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3255 When the command is given by user we register a pending command
3256 callback that will reprocess the command after the reply has been
3257 received from the server. When reprocessing the packet we then
3258 display the information. Thus, the USERS information is displayed
3259 now in the command callback instead of in the command reply
3260 callback. The processing of the command is same as previously
3261 when server has sent the command reply in the JOINing process.
3263 * Added to USERS command in silcd/command_reply.c to join the client,
3264 we didn't use to know about, to the channel after we've created
3265 a client entry for it. Also, for clienet we did know already still
3266 check whether it is on the channel or not and add it if not.
3268 * Removed silc_server_command_join_notify as the function and its
3271 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Changed the client's pending command handling to the same as the
3274 server's pending command handling. It is also now possible to
3275 execute command reply functions from other command reply
3276 function as the function callbacks for commands and command
3277 replies are one and same. The pending commands are not static
3278 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3279 in client connection context. Thus, pending commands are server
3280 connection specific as it is convenient.
3282 Changed the function silc_client_command_pending and
3283 silc_client_command_pending_del and added new function
3284 silc_client_command_pending_check. Removed the
3285 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3288 * Added cmd_ident, current command identifier, to the client
3289 connection context in lib/silcclient/client.h to keep track on
3290 command identifiers used in command sending. Client's command reply
3291 function handling now supports the mandatory command identifiers.
3293 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3294 funtions in client to fully support pending command callbacks.
3296 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3297 as one of the arguments to the application in the command reply
3300 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3301 before first releasing SILC but came back. Now it is removed again
3302 and should come back nomore. The FORWARDED flag was used only
3303 by the JOINing procedure by forwarding the command packet to router.
3304 Now, the JOINing procedure has been changed to more generic (due
3305 to various router environment issues) and FORWARDED is not needed
3306 anymore for anything. The protocol specification is yet to be
3309 Now, removed silc_server_packet_forward from server and the flag
3310 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3312 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Renamed NAMES command to USERS command. The NAMES was named that
3315 due to historical reasons. Now it is renamed. Also, rewrote
3316 parts of the USERS command. The nickname list is not sent anymore
3317 by the server. Only Client ID and mode lists are sent in the USERS
3318 command. Changed this also to the protocol specification.
3320 The client now resolves the names and stuff after it receives
3321 the USERS list from the server when joining to the channel.
3323 * WHOIS and IDENTIFY commands has been changed to support multiple
3324 Client ID's per command. One can now search for multiple users
3325 in the network by sending only one WHOIS or IDENTIFY command.
3326 Changed the code and the protocol specifications.
3328 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3329 uses silc_server_command_whois_parse to parse the request. */
3331 * If normal server, do not parse the WHOIS and IDENTIFY requests
3332 before sending it to the router. Saves some time.
3334 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Fixed JOIN command on client library. Wrong number of arguments
3337 used to crash the client.
3339 * Added silc_server_channel_has_global function to check whether
3340 channel has global users or not.
3342 * Added silc_server_channel_has_local function to check whether channel
3343 has locally connected clients on the channel.
3345 * The silc_server_remove_from_one_channel now checks whether the
3346 channel has global users or not after given client was removed from
3347 the channel. It also checks whether the channel has local clients
3348 on the channel anymore. If it does not have then the channel entry
3349 is removed as it is not needed anymore.
3351 * The silc_server_notify now checks on JOIN notify whether the joining
3352 client is one of locally connected or global. If it is global then
3353 the channel has now global users on the channel and that is marked
3354 to the channel entry. Also, it now saves the global client to
3355 global list who is joining and JOINs it to the channel. This is
3356 for normal server, that is.
3358 Changed silc_server_send_notify_on_channel,
3359 silc_server_packet_relay_to_channel and
3360 silc_server_packet_send_to_channel check if we are normal server
3361 and client has router set (ie. global client) do not send the
3362 message to that client, as it is already routed to our router.
3364 * Implemented LEAVE notify type handling in silc_server_notify
3367 * Tested LEAVE command in router environment successfully. Tested
3368 with two routers, two servers and two clients.
3372 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3374 * Implemented SIGNOFF notify type handling in silc_server_notify
3377 * silc_server_remove_id now removes the client entry from all channels
3378 it has joined and thusly sends SIGNOFF notify type.
3380 * Rewrote the NAMES list generation in server by removing two excess
3381 loops. The lists are created now inside one loop.
3383 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * silc_server_remove_channel_user checks now also global list
3386 for channel and client.
3388 * silc_server_new_channel_user checks now both local and global
3389 list for channel and client. Fixed a bug in client id decoding.
3390 Used to decode wrong buffer.
3392 * silc_server_channel_message checks now both local and global
3393 list for channel entry.
3395 * Tested channel joining (hence JOIN) in router environment
3396 successfully. Tested with two routers, two servers and two
3399 * Tested channel message sending in router environment successfully.
3401 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3403 * Added silc_server_save_channel_key into server.[ch] to save the
3404 received channel key in Channel Key payload processing. It is
3405 also used in JOIN command reply handling.
3407 Equivalent function silc_client_save_channel_key added into
3408 client.[ch] into client library.
3410 * Changed JOIN command reply to send information whether the channel
3411 was created or not (is existing already) and the channel key
3412 payload. Changed protocol specs accordingly.
3414 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3415 the request was sent by ID and not by nickname. Crashed on
3418 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3420 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3421 now correctly save the received data.
3423 * silc_server_free_sock_user_data now notifies routers in the
3424 network about entities leaving the network.
3426 At the same time implemented functions silc_server_remove_id
3427 and silc_server_send_remove_id to receive and send REMOVE_ID
3428 packets. The packet is used to notify routers in the network
3429 about leaving entities. The ID removed will become invalid in
3432 * Added function silc_idlist_del_server into server. Removes and
3433 free's server entry from ID list.
3435 * silc_server_private_message function now checks, if we are router,
3436 that the destination ID really is valid ID, naturally.
3438 * In router when NEW_ID packet is received (for new client) the
3439 hash of the Client ID is saved in the ID Cache but the
3440 client->nickname is set to NULL, instead of putting the hash
3443 IDENTIFY command now also checks that client->nickname must be
3444 valid. If it is not if will request the data from the server who
3445 owns the client. Added new function
3446 silc_server_command_identify_check.
3448 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3449 to set the command to already allocated Command Payload.
3451 * Tested private message sending in router environment with two
3452 routers, two servers and two clients. Fixed minor bugs and now
3455 * Fixed segfault from client's NAMES command. Used to crash if
3458 * Forwarded packets must not be routed even if it is not destined
3459 to the receiver. Changed server code comply with this.
3461 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Added `require_reverse_mapping' boolean value to ServerParams
3464 structure. If TRUE (not default) the server will require that
3465 the connecting host has fully qualified domain name.
3467 If the reverse mapping is not required and hostname could not be
3468 found the IP address is used as hostname.
3470 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * Implemented version string checking to both client and server.
3473 The check is incomplete currently due to the abnormal version
3474 strings used in development version of SILC.
3476 * Changed all command functions in server to use the new
3479 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Changed char *data to unsigned char *data in ID Cache system to
3482 support binary data as ID Cache data. Changed code to support
3483 binary data in lib/silccore/idcache.c.
3485 * Renamed silc_server_packet_relay_command_reply to
3486 silc_server_command_reply as it is normal packet receiving
3487 function. Rewrote the function to accept command replys for
3488 servers and not only for clients.
3490 * Mark remote router always as registered server if we are connecting
3491 to it. Otherwise, commands sent by the router to us are ignored.
3493 * All ID List find routines now returns the ID Cache Entry pointer
3494 as well if requested.
3496 * WHOIS command works now in router environment, tested with two
3497 routers, two servers and two clients.
3499 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3500 in router environment (as it is almost equivalent to WHOIS) but
3501 hasn't been tested thoroughly. Added new functions:
3503 silc_server_command_identify_parse
3504 silc_server_command_identify_send_reply
3505 silc_server_command_identify_from_client
3506 silc_server_command_identify_from_server
3508 * Disabled route cache adding because adding two different ID's with
3509 same IP replaces the old cache entry thus giving wrong route.
3510 The entry->router->connection is always the fastest route anyway
3511 so route cache may not be needed. Of course, new routes maybe
3512 established after receiving the ID when the entry->router->connection
3513 might not be anymore the most optimal.
3515 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Add route cache for received ID for fast routing.
3519 * Added silc_server_packet_route to route received packet on router
3520 that is not destined to us.
3522 * Renamed silc_server_get_route to silc_server_route_get.
3524 * Added id_string and id_string_len fields into SilcServer to
3525 include encoded ServerID for fast comparing without excess
3526 encoding of the ID's.
3528 * Cleaned up WHOIS command on server side. Added following static
3531 silc_server_command_whois_parse
3532 silc_server_command_whois_check
3533 silc_server_command_whois_send_reply
3534 silc_server_command_whois_from_client
3535 silc_server_command_whois_from_server
3537 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3538 arguments in command replies. All command functions should be
3539 updated to use this macro.
3541 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Minor typo fixes on command reply handling on server.
3545 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Added silc_server_command_add_to_channel internal routine to add
3548 the client to the channel after router has created the channel and
3549 sent command reply to the server.
3551 * Added generic silc_server_send_command to send any command from
3554 * Use static buffer with ID rendering instead of duplicating data.
3556 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Fixed a channel user mode bug when joining to a channel server gave
3559 everybody channel founder rights, oops.
3561 * We mark ourselves as the router of the incoming server connection
3562 if we are router ourselves. This way we can check in some packet
3563 sending functions whether it is locally connected server. For
3564 incoming router connections we put NULL.
3566 * For router sending packets locally means now always sending the
3567 packet cell wide; to local clients and local servers. For normal
3568 server sending packet locally means sending it to only local
3571 * Fixed the JOIN command to really work in router environment. If the
3572 channel is created it is always created by the router. Router is
3573 also responsible of making the initial joining to the channel,
3574 sending JOIN notify to the sending server and distributing
3575 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3576 does not exist server doesn't do anything else but forward the
3577 command to the router which performs everything.
3579 * Added silc_server_send_channel_key function to send the Channel Key
3582 * Added silc_server_create_channel_key to create new channel key. The
3583 channel key is now re-generated everytime someone joins or leaves
3584 a channel, as protocol dictates. Note: channel->key_len is the
3587 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3589 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3590 packet_receive.[ch] to separate packet sending and receiving
3591 routines. The server.[ch] now includes everything else including
3592 actual packet processing (writing and reading data) and other
3595 Renamed silc_server_private_message_send_internal to
3596 silc_server_send_private_message. The routine is still though
3597 used only to relay private messages as server does not send
3598 private messages itself.
3600 Renamed silc_server_new_channel to silc_server_create_new_channel
3601 and added new function sicl_server_new_channel that handles the
3602 incoming New Channel packet. Added also new sending function
3603 silc_server_send_new_channel to send New Channel Payload.
3605 * Added new function silc_server_notify to process incoming notify
3606 packet to the server/router. Server may then relay the notify
3607 to clients if needed.
3609 * Added new function silc_server_new_channel_user to process incoming
3610 New Channel User packet. Router will redistribute the packet and
3611 send JOIN notify to its local clients and locally connected servers
3612 if needed. Normal server will send JOIN notify to its local client
3613 on same channel when received this packet. Added also corresponding
3614 sending function silc_server_send_new_channel_user to sent the
3617 * Added boolean route argument to send_notif_to_channel and
3618 packet_send_to_channel functions to attempt to route the packet
3619 if it is TRUE and send only locally if it is FALSE.
3621 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3623 * silc_server_replace_id now broadcasts the received replace ID
3624 packet if it is not broadcast packet already. The router must
3625 broadcast to inform other routers about changed ID.
3627 * Added backpointer to server's router into SilcServer context in
3628 silcd/server_internal.h.
3630 * Fixed silc_server_packet_broadcast to send correct broadcast
3633 * The channel key is now distributed to the local client as soon
3634 as it is received from the router (in router environment) so that
3635 no other packet may be sent for the channel until client has
3638 * silc_server_remove_channel_user now broadcasts the received
3639 Remove Channel User packet if it is not broadcast packet already.
3640 The router must broadcast to inform other routers about removed
3643 * Added users field into SilcPacketContext that is a reference count
3644 of the context. One can increase the reference count by calling
3645 silc_packet_context_dup which is now changed to just increase the
3646 reference count instead of duplicating the data. The reference
3647 count is decresed by calling silc_packet_context_free that will
3648 free the data after the reference count hits zero.
3650 For now on the packet context and everything allocated into it
3651 (including the raw packet from network) must be freed by calling
3652 the new silc_packet_context_free function. Added also new function
3653 silc_packet_context_alloc that must be used now to allocate the
3654 context. This also means that if a routine is asynchronous from
3655 silc_[client/server]_packet_parse_type the packet context must
3656 be duplicated by calling silc_packet_context_dup. Otherwise it
3657 gets free'd after silc_[client/server]_packet_parse_type returns.
3658 Also, one must remember that if packet is duplicated then its
3659 reference count must be decresed by calling the free function as
3660 many times as it was duplicated.
3662 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3663 from both client and server.
3665 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Made joining to a channel working in router environment.
3669 * Cleaned up JOIN command on server side and create function
3670 silc_server_command_join_channel internal routine to make the
3673 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Changed silc_command_pending list to SilcDList. Also, added
3676 `ident' field to SilcServerCommandPending structure to identify
3677 the reply and to call correct callback.
3679 Added silc_server_command_pending_check function to replace the
3680 corresnponding macro. The silc_command_pending list is not
3683 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3684 to set identifier to previously allocated Command Payload. It
3685 is used to set identifier for command when resending Command
3688 * Added silc_command_payload_encode_payload to encode Command
3689 Payload buffer from SilcCommandPayload structure.
3691 * Added silc_argument_payload_encode_payload to encode Argument
3692 payload buffer from SilcArgumentPayload structure.
3694 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * Changed WHOIS command to support router connection on server side.
3697 The whois request is always sent to router unless the server is
3698 standalone server. After server has received the reply from the
3699 router will it send the reply to the client.
3701 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3702 broadcast received broadcast packet. The function is used only
3703 by router. The broadcast packet is always sent to the router's
3706 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3707 render given ID to printable string, for log files for example.
3709 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * Made basic router to router connections working. At least they
3712 can now connect to each other but nothing really works the way
3713 they are supposed - yet.
3715 * Added new initiator token to RouterConnection configuration
3716 file in silcd/serverconfig.[ch]. It is used to tell whether we
3717 are the initiator to the remote router or whether we'll expect
3718 the other end to connect.
3720 * Moved registering of listener task to silc_server_init, hence
3721 the server starts listenning as soon as it is run, even if it
3722 does not have connections to other routers. Let's see how well
3725 * Changed default connection retry timeouts for more suitable in
3728 * Removed cipher and such arguments from silc_idlist_add_client
3729 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3730 Added new function silc_idlist_add_data to add the keys and stuff
3733 * Added SilcIDListData structure and added it to SilcClientEntry
3734 and SilcServerEntry as their first field in the structure. This
3735 way we can explicitly cast the ID entries to the SilcIDListData
3736 structure and get common data for the entries. In past, we had
3737 to first check what type of connection it is and then cast it to
3738 correct ID entry type. Now, we can directly cast the opaque
3739 pointer to the SilcIDListData (no matter what ID entry it actually
3740 is) and get the data needed.
3742 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3745 in some circumstances even if threre were timeout tasks, though not
3746 IO tasks, but tasks anyway. Now fixed.
3748 * Defined SilcServerConnection structure to hold connection specific
3749 stuff about directly connected servers and routers. The definition
3750 is currently in silcd/server_internal.h. I thought about having
3751 a bit more important role fro this struct but for now it is used
3752 only when connecting to other server (or router actually).
3754 * Added connecting retry support in server when connecting to
3755 router(s). The retry feature implement exponential backoff
3756 algorithm. Also, added SilcServerParams structure to hold default
3757 parameters for server. For now, it include these retry settings
3758 and are hard coded. After server is moded to be as Silc Server
3759 Library this structure will be more important.
3761 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Changed client librarys channel->clients table to SilcList and
3764 changed code accordingly.
3766 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Changed client's channel table to SilcList and changed code
3769 accordingly. Also changed SilcChannelClientEntry to include back-
3770 pointer to the channel so that client entry can use that structure
3771 as list as well and we have fast cross-reference to the channel.
3772 This change dramatically decreased the complexity of channel
3773 handling with client entry and vice versa (removed one extra
3774 loop when searching for channel entry from many functions).
3776 * Changed server->sim from table to SilcDList and changed code
3779 * NAMES command can now be used from user interface. It will show
3780 the user list on the channel, neatly.
3782 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3783 Code now saves realname of the user if it becomes available.
3785 * Renamed configure.in to configure.in.pre and made ./prepare
3786 script to automatically add correct version string to
3787 configure.in which it creates from configure.in.pre.
3789 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * NAMES command reply now shows users mode with the nickname when
3794 * Moved silc_client_ch[u]mode[_char] functions from
3795 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3796 place sucks, they are utility functions and should be in some
3799 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3801 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3804 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3808 * Added TRQ (efficient deque and list library) into lib/trq. This is
3809 a very good list library that is currently used in the SILC. Defined
3810 SilcList API over the library because I didn't like the API very
3811 much. See lib/trq/silclist.h for the API and examples of how to
3812 use the API. Fixed various places in the code to use the new
3813 SilcList API. The SilcList is meant for lists that has a structure
3814 already defined as a list. It is not suitable to add just some
3815 context to the list (in TRQ, the context is the list actually).
3817 So, I defined SilcDList that can be used for the purpose where
3818 predefined list structure does not exit. This can be used as
3819 such list. Now some context just can be added to the SilcDList.
3820 Currently this list is not used in the SILC just yet, though there
3821 are a lot places where this can replace dynamically allocated
3822 tables and I will fix these places, later, to use SilcDList.
3823 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3824 and use TRQ internally).
3826 Also fixed some annoying warning messages that the original TRQ
3827 code generated. Also minor changes to TRQ's Makefile.in.
3829 * Added support for querying by Client ID to both WHOIS and
3830 IDENTIFY commands into server, as required by the protocol.
3832 * Removed method function pointers from SilcBuffer structure. They
3833 weren't used to anything and just increased the context size for
3834 no good reason. This change also made silc_buffer_alloc and
3835 silc_buffer_free functions inline functions.
3837 * Disabled command flooding detection support until it's fixed so
3838 that it accepts commands in but does not execute them more than once
3841 * Added silc_net_localhost(), to return local hostname, into
3842 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3843 that must be initialized before calling silc_client_init.
3845 * Added new function: silc_server_send_notify_on_channels to send
3846 notify messages to all channels client has joined. It is assured
3847 that the message is sent only once per client.
3849 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3850 lib/silcutil/silcutil.[ch] as silc_format function. The new
3851 function is generic and is used by server as well, not only by
3852 the logging routines.
3854 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3855 the provided version string was not acceptable. Added new function:
3856 silc_ske_check_version into lib/silcske/silcske.h. The function
3857 must be implemented by the application (client or server) and it
3858 does not reside in the SKE library. The function checks the version
3859 string remote end sent.
3861 * Added back pointers (to opaque context and to SilcSocketConnection)
3862 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3864 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3865 duplicate packet context structure.
3867 * Changed `notify' client operation to send same arguments as client
3868 receives from server except for ID's. ID's are mapped to correct
3869 ID entry and that is returned. Also, if channel entry is not sent
3870 by server but the notify is for channel the channel entry is sent
3871 to application (otherwise application doesn't know that it is for
3872 channel (library gets it from packet's Destination ID)).
3874 * Added silc_client_remove_from_channels into client library to
3875 remove a client from all channels it has joined to. Used when
3876 received SIGNOFF notify from server. Added also new function
3877 silc_client_replace_from_channels to replace old ID entry with
3878 new ID entry on all channels. Used when received NICK_CHANGE
3881 * Fixed ID Cache list handling in silc_idlist_get_client in
3882 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3883 to get (or query) client by ID.
3885 * Updated TODO list.
3887 * Added connection authentication status message defined by the
3888 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3889 support for these into the code in client and server side.
3891 * Added generic function silc_client_send_command to send any command
3892 with variable argument list. Application should use this function
3893 to send commands if the command functions provided by the library
3894 does not suite for the application's user interface needs.
3896 * Added new `failure' client operation. Application is notified about
3897 received failure packet if client is executing a protocol. In this
3898 case the protocol's execution has failed.
3900 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3901 is required by the protocol.
3903 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3904 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3907 * Added status flag to SilcSKE object to indicate realtime status
3908 of the SKE protocol.
3910 * Application receives now exactly same command reply arguments as
3911 the library receives from server. However, if ID is received the
3912 corresponding ID entry is returned to the application (eg. Client
3913 ID is mapped to correct SilcClientEntry entry and that is returned).
3914 Changed command_reply client operation due to this change.
3916 * Changed all ID's in commands and in command replys as ID Payloads.
3917 Change affected both client and server side codes.
3919 All ID's sent in SILC network (with execption of ID's in SILC
3920 Packet header) are sent in ID Payload to support variable length
3923 * Server now notifies nick changes and notifies all clients on
3924 the channels about the new nickname (about the new Client ID,
3927 * Implemented CMODE command to change channel modes. Supports all
3928 channel modes defined by the protocol specs except ban and invite
3929 lists. (Also, private channel key mode is supported but support for
3930 setting private channel key in client is missing, thus, this mode
3931 has no effect on client side (except that server requires that the
3932 client uses private channel key and normal channel traffic does not
3935 Also, invite mode works per se, but INVITE command does not work
3936 yet correctly, so you can set channel as invite only channel but
3937 inviting clients to the channel does not work (it is yet to be
3938 thought what's the best way to do it).
3940 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3941 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3942 Implemented CUMODE command to change user's mode on the channel.
3943 Supports all modes defined by the protocol specs.
3945 * Added NAMES command reply to return users modes on the channel.
3947 * Removed unnecessary and slow ciphers from lib/silccrypt.
3949 * Set SO_KEEPALIVE option to connection sockets by default.
3951 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3953 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3954 redefined the Notify Payload into protocol specs.
3956 * Added silc_id_payload_parse_id to get ID directly from raw
3959 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3962 accept searching by Client ID as well.
3964 * Added support for LEAVE and SIGNOFF notify types in client library.
3966 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3967 to parse ID Payload from raw data.
3969 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Added flags parameter into silc_ske_assemble_security_properties
3972 function in lib/silcske/silcske.[ch].
3974 * Changed notify client operation to fit better for notify messages
3975 sent by server. The notify payload received from server is now
3976 passed to the application (after parsing it to SilcNotifyPayload).
3977 It is application's responsibility to retrieve the arguments
3978 from the payload and show the message the way it wants. The message
3979 sent by server is implementation specific.
3981 * Changed public keys to comply with the protocol specification.
3982 Old public keys are not supported anymore and are not compatible.
3984 * Removed nickname from Channel Payload as the latest draft removed
3985 it. The client must resolve the nickname from the NAMES command
3986 reply received when it joined the channel.
3988 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3990 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Fixed some errors in protocol specification drafts.
3994 * Created lib/silccore/silcnotify.c to implement Notify Payload
3995 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3996 generic payloads described by protocol specifications. The file
3997 includes implementations for ID Payload and Argument Payload.
3999 * Changed Command Payload implementation to use the new Argument
4000 Payload. Changed command_xxxx_payload to command_payload_xxxx
4001 to comply with SILC coding conventions.
4003 * Added suppport for Argument Payload handling in Notify Payload
4004 implementation as protocol requires it. Added the new support
4005 into server and client lib as well.
4007 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Added support for multiple nicknames on same channel. [n] is
4010 added locally to the nickname if there are more than one same
4011 nicknames on the channel.
4013 * Server now sends all nicknames that matched WHOIS request.
4014 Client also shows the list received from server.
4016 * Added TOPIC command to client side. User can now set and show
4017 current topic on channel.
4019 * Added MOTD command to client and server. Also, server sends the
4020 motd when client connects to the server.
4022 * Changed version strings to comply ISO 8601.
4024 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Fixed protocol error handling in client library. It should now
4027 cope even if the SKE fails for some reason.
4029 * Made new protocol specification drafts for submitting to IETF.
4031 * Implemented TOPIC command to server in silcd/command.c.
4033 * Added two new notify types into lib/silccore/silcnotify.h:
4034 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4035 notify nickname change and topic setting/change on a channel.
4037 * API change of command_reply operation in client library. The
4038 application gets now the status type received from server as well.
4040 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4044 * Cras fixed and optimized the packet handling even further and
4045 it should work now. Minor change to the prototype of function
4046 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4048 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Added new function into lib/silcutil/silcschedule.[ch]:
4051 silc_schedule_with_fd to select() a specified fd. The function
4052 returns after timeout expires or data arrives or goes. The
4053 function is used by packet routines to wait that all data is
4054 received from network.
4056 * Fixed data reading from network in lib/silccore/silcpacket.c.
4057 The code now assures that all data is read from the fd and then
4058 continues packet processing. This was a bug fix since the code
4059 used to drop some data in some circumstances.
4061 * Added new function into lib/silcclient/client.[ch]:
4062 silc_client_start_key_exchange to start key exchange after
4063 connection has been established to server. The code internally
4064 now uses this funtion but its main purpose was to provide it
4065 for applications that perform their own connecting. After
4066 application has created a connection it merely calls this
4067 function to start the key exchange between client and server.
4068 The library takes care of everything else after that.
4070 Updated also lib/silcclient/README to explain the usage of
4073 * Do not send to application information that connection has
4074 been established. Application gets notified it by connect
4077 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Applied cras's patch to add silc_schedule_one function. The
4080 function runs scheduler once and returns.
4082 * Fixed the scheduler after cras messed it up. The timeout
4083 handling works now as it's supposed to work.
4085 * Added into lib/silccore/ silcnotify.h to include notify
4086 message types support. Changed silc_server_send_notify*
4087 functions, in server.[ch], to support those new notify types.
4088 Added the support for the notify types into client library,
4089 as well. Added new notify client operation into ops.h in
4092 * Changed silc_server_packet_send_to_channel to send normal
4093 packets instead of just channel message packets. The function
4094 is now used to send the notify packets to channels. It is not
4095 used to send channel message packets anymore, as server never
4098 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4099 va_arg()s as it seems to require it nowadays. I guess, if SILC
4100 is compiled with older va_arg() the new code should work anyway.
4102 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Splitted core library. Core library (lib/silccore) includes
4105 now only SILC protocol specific core (and common) components.
4106 Created new utility library (lib/silcutil) that includes more
4107 generic purpose stuff. The stuff for util library was taken
4108 from the old core library. This was minor and easy split.
4110 * Created SILC Client Library (lib/silcclient) that includes
4111 implementation of the SILC client without user interface. This
4112 was major move from silc/ directory. The code has been changed
4113 so that it is transparent towards the user interface. The
4114 silc/ directory includes now the same user interface as before
4115 and it uses the new client library. Read lib/silcclient/README.
4116 Basicly, the client library performs everything else related
4117 to SILC except user interface handling. Also, configuration
4118 files are considered to be part of user interface and library
4119 does not handle them.
4121 This change also changed a lot of structures, function naming etc.
4122 Most important change was that SilcClientWindow object was
4123 renamed to SilcClientConnection in the client library. Created
4124 also new file lib/silcclient/ops.h. Also added new files
4125 silc/local_command.[ch] and silc/client_ops.[ch].
4127 All these changes were made to make it easier for user interface
4128 designers to create what ever user interface for the SILC client
4131 It is also expected that the server will be moved to lib
4132 directory as well and SILC Server Library will be created;
4133 sometimes in the future.
4135 * Removed Local commands from lib/silccore/silccommand.h as
4136 they are application specific and new client library does not
4137 handle any of those anymore.
4139 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4140 old client implementation in silc/.
4142 * Added support for callback functions in SILC_LOG_* macros.
4143 Application can now set its own callbacks that will be called
4144 instead of using the default functions that will always print
4145 the debug messages to stderr (or stdout). Also, debugging can
4146 now be disabled by setting silc_debug to FALSE and re-enabled by
4147 setting it to TRUE. Note, that logging will still work even
4148 if debugging is disabled.
4150 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4151 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4152 silc_log_reset_debug_callbacks.
4154 * To enable debugging in silc client one must give now -d
4155 option on command line.
4157 * Changed silc_schedule_init to automatically allocate task queues
4158 if they are not allocated before calling it.
4160 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Added GMP 3.1 into math library.
4164 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4167 a channel in SILC network. The packet is used by servers and
4168 routers to notify other routers that user has left a channel.
4169 This little feature was missing until now. Added the feature
4170 to protocol specification as well.
4172 Added functions: silc_server_send_remove_channel_user and
4173 silc_server_remove_channel_user into server.[ch].
4175 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4176 lib/silccore/silcpacket.h. However, they are not implemented
4179 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Fixed joining to a channel and sending channel messages
4182 between server and router. The channel message sending should
4183 now work inside a cell.
4185 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Fixed the private message sending between server and router.
4188 The private message sending should now work inside a cell.
4190 * Added silc_server_replace_id into server.[ch] to replace
4191 existing ID in the SILC network.
4193 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4194 and silc_idlist_replace_server_id into idlist.[ch] in server.
4196 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4198 * Fixed the server to server connections. Server can again now
4199 connect to router. Router to router connections probably does
4202 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4204 * Added dynamic protocol registering support. Now protocols can
4205 registered and unregistered on the fly. Patch by cras.
4207 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Added lib/contrib directory to hold routines that some platforms
4210 don't have but are needed by SILC.
4212 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4213 into lin/contrib to provide getopt() and getopt_long() for
4214 those who don't have it.
4216 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Added AWAY command to client. When away message is set and
4219 client receives a private message packet the client automatically
4220 replies to the sender with the away message.
4222 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4223 bug seemed to be the cause of recent problems when compiling
4226 * Added version detection support to SKE protocol specification
4227 and added the new changes to the SKE implementation as well.
4228 There were other minor changes in the SKE protocol as well.
4230 Many changes in lib/silcske/silcske.[ch] and in
4231 lib/silcske/payload.[ch].
4233 * Added ^U functionality, clear input line. Patch from cras.
4235 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Mainly small bugfixes on core library. Fixed some debugging
4238 logging and buffer overflow in silclog.c.
4240 * Updated config.sub and config.guess on the distribution tree.
4242 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Added command lagging support in server. Client may execute
4245 commands now only once in two seconds.
4247 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Optimized packet reception. MAC computation and checking is now
4250 also more optimized. A lot previously duplicated code is now
4251 used as generic by both client and server.
4253 * Fixed key pair generation in clientutil.c
4255 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Added into lib/silccore/silcbufutil.[ch] new function;
4258 silc_buffer_realloc.
4260 * Moved generic packet sending/encryption functions to
4261 lib/silccore/silcpacket.[ch] from client and server. Some
4262 rewriting of the functions.
4264 * Moved all generic packet reception/decryption functions to
4265 lib/silccore/silcpacket.[ch] from client and server. The
4266 packet processing is now much cleaner in both client and server.
4267 These were major changes in both client and server.
4269 * Created many common functions in server to do packet sending.
4270 Previously code were duplicated a lot, this has been removed
4273 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Rewrote major parts of the ID cache system. Don't know
4276 whether it is better now or not but at least the API is more
4279 * Major rewrite on ID cache stuff on client because of the ID
4280 cache API changes. Added idlist.c to client.
4282 * Also major rewrite on ID cache stuff on server as well.
4283 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4284 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4285 in hand, instead they are all put into the ID cache system now.
4286 All server_idlist_* routines uses ID cache now instead of
4287 traversing its own lists (those lists does not exist anymore).
4288 SilcIDList though still exists. Also, SilcXXXEntry's are
4291 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4293 * Finally made the SKE implementation compliant to the protocol
4294 specification. All mp integers are now binary encoded as
4295 opposed being HEX encoded.
4297 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4300 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4301 functions: silc_[encode/decode]_pem. Also added function
4302 silc_encode_pem_file to PEM encode with newlines ('\n') for
4305 * SILC public keys are now encoded either PEM or binary. Same
4306 option is for private keys as well. By default private keys
4307 are binary encoded and public keys PEM encoded. Silly HEX
4308 encoding were removed.
4310 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4311 function to create fingerprints.
4313 * Fixed a bug in SHA1; does not change the original data anymore.
4315 * Partly implemented INFO command on client and server side.
4316 Fixed CLEAR command. Changes to SERVER command; show current
4317 server(s) when giving command without arguments. Added
4318 VERSION command to client.
4320 * Added check to server that unregistered connections cannot
4321 execute commands (unless it is specificly allowed).
4323 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Fixed screen refresh.
4327 * Fixed channel joining bug from client. On some circumstances
4328 client tried to join to a channel it had already joined.
4330 * Added public key verification process into client's protocol.c.
4331 The client now verifies the public key from user and saves
4332 it into ~./silc/serverkeys/ directory.
4334 Added into: clientutil.[ch]: silc_client_verify_server_key.
4336 * Changed SKE protocol's silc_ske_initiator_finish function
4337 to accept callback function that verifies the received public
4338 key. Removed old silc_ske_verify_public_key function.
4340 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4343 silc_pkcs_private_key[_data]_set.
4345 * Made the password and public authentication more cleaner in
4346 server's protocol.c.
4348 * Removed historic and obsolete protocol `channel_auth' from
4349 both client and server.
4351 * Removed wrong way of sending command status messages from
4352 server to client in server's command.c. The old way violated
4353 protocol specification.
4355 Changes to silccore/silccommand.[ch]: removed
4356 silc_command_encode_status_payload -> not needed anymore,
4357 changed silc_command_encode_payload_va to accept extra
4358 argument on variable argument list. The argument type must
4359 now be provided to the function. Also, added new function:
4360 silc_command_encode_reply_payload_va which is same as
4361 normal command_encode_payload_va except command status type
4362 is provided as extra argument.
4364 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Added ~./silc directory handling. The directory includes the
4367 public and private keys for the client.
4369 Added silc_client_check_silc_dir, silc_client_create_identifier
4370 and silc_client_load_keys.
4372 * Implemented SILC protocol compliant public key. Added public
4373 and private key saving to and loading from files.
4375 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4376 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4377 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4378 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4379 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4381 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4382 silc_pkcs_load_[public/private]_key.
4384 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Added silc_server_get_route (route.[ch]) to get connection
4387 data for the fastest route for given ID.
