1 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed the silc_server_remove_clients_by_server's channel
4 key re-generation. The hash table handling was incorrect
5 and would not work with many channels. Affected file is
8 * Fixed some memory leaks around the server code.
10 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
12 * Changed the dynamic tables to static size tables in the
13 lib/silccrypt/silchmac.c.
15 * Removed GCC dependencies from the code. A patch by cras.
17 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
19 * Do not show the error "Error receiving packet bla bla"
20 in server if it really was not an error (-2 means that reading
21 is pending). Affected file silcd/server.c.
23 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
25 * Fixed a possible crash in silc_server_remove_clients_by_server
26 in silcd/server.c. Fixed there also some memory leaks.
28 * Fixed the silc_idlist_replace_client_id. It could replace
29 wrong key in the hash table. Affected file silcd/idlist.c.
31 * Do not check whether there are global users on the channel
32 if the channel->global_users is FALSE. Affected functions
33 silc_server_remove_from_one_channel and
34 silc_server_remove_from_channels in silcd/server.c. Also,
35 do not check if the removed client is local as we can be
36 sure that global client was not removed from the channel
37 and checking for global users is not needed.
39 * The silc_server_remove_clients_by_server now re-generates
40 the channel keys correctly for those channels that had
41 clients removed from them. Affected file silcd/server.c.
43 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
45 * Found the reason of random crashes in the server. We weren't
46 ignoring the SIGPIPE signal (which can be sent in write())
47 and it crashed the server. Affected file silcd/silcd.c.
49 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
51 * Assure that sock->user_data is not NULL in the function
52 silc_server_packet_send in silcd/packet_send.c.
54 * Disconnect the remote connection if it could not be added
55 to any ID lists in the server. The affected file is
58 * Check in silc_server_packet_send[_real/dest] that the
59 socket is not disconnecting and ignore the data if it is.
60 Affected file silcd/packet_send.c.
62 * Define inline to __inline on native WIN32 compilation.
63 Affected file includes/silcwin32.h.
65 * Added some explicit type casts for inline code since MSVC
66 require them. Affected files lib/silcutil/silcbuffer.h,
67 lib/trq/silcdlist.h and lib/trq/silclist.h.
69 * Print warning in log files from now on if the packet
70 decryption fails. Affected file silcd/server.c.
72 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
74 * Changed the `say' client operation's interface to accept
75 new `type' argument to indicate the type of the message sent
76 by the library. The application may filter the library's
77 messages according the type. The affected file is the
78 lib/silcclient/silcapi.h.
80 * Added two new functions to lib/silcclient/silcapi.h:
81 silc_client_del_client and silc_client_del_client_by_id.
82 Affected file lib/silcclient/idlist.c.
84 * Moved the clientincludes.h from includes/ to silc/ and
85 serverincludes.h from includes/ to silcd/.
87 * The modes for the CMODE and CUMODE are now passed as
88 uint32 for application with COMMAND_REPLY. The affected
89 file is lib/silcclient/command_reply.c.
91 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
93 * /WHOIS without arguments shows client's own information.
94 Affected file lib/silcclient/command.c.
96 * Changed PING to not accept any arguments. The specs
97 says that client can ping only the connected server so
98 requiring an argument is not needed. Affected file is
99 lib/silcclient/command.c.
101 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
103 * Fixed a fatal bug in private message sending and reception
104 encryption and decryption when using private message keys.
105 The implementation was incorrect and did not follow the
106 specification. It causd that some of the message were
107 lost since it did not use the sending and receiving keys
108 as the protocol suggests. This has been fixed and will cause
109 incompatibilities with older clients when sending private
110 message encrypted with private message keys. Affected files
111 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
112 and various other in Irssi SILC Client.
114 Added `responder' boolean argument to the functions
115 silc_client_add_private_message_key[_ske] to indicate when
116 the key is added as responder or initiator of the key
119 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
121 * Removed the silc_ske_check_version function and created
122 a SilcSKECheckVersion callback. Added also a function
123 silc_ske_set_callbacks that is now used to set all SKE
124 callbacks. The callback functions are not given to
125 the SKE functions anymore, but this function is used to
128 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
130 * Added `silc_version' argument to the silc_client_alloc
131 to define the version of the application for the library.
132 The library will use the version string to compare it
133 against the remote host's (usually a server) version
134 string. Affected file lib/silcclient/silcapi.h
136 * Added the KE protocol context to Key Agreement context
137 in client library so that we can abort the SKE if it
138 is in process when we get timeout. Affected file is
139 lib/silcclient/client_keyagr.c.
141 * Do not resolve the client ID forever if it returns in the
142 first time that such client does not exist. This was done
143 for example with private message. Affected file is
144 lib/silcclient/client_prvmsg.c.
146 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
148 * Do not add regex.h for WIN32. The affected file
149 includes/silcincludes.h.
151 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
152 not work yet 100%. It generates the DLL's automatically
153 when compiling with --with-win32 under cygwin.
155 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
157 * lib/contrib/regex.c is not compiled on WIN32.
159 * Added silc_net_get_socket_opt function to the
160 lib/silcutil/silcnet.h.
162 * Added includes/silcwin32.h for WIN32 specific includes
165 * Do not use ptime structure or any of the posix process
166 functions on WIN32 in lib/silccrypt/silrng.c.
168 * Added silc_gettimeofday to provide generic function
169 for struct timeval on all platforms. Added the function
170 to lib/silcutil/silcutil.h.
172 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
174 * Moved the lib/silccore/silcsockconn.[ch] to the utility
175 library as they clearly belong there. As a plus side we
176 can make the actual socket connection routines platform
179 Added also new generic function silc_socket_read and
180 silc_socket_write (that used to be silc_packet_[read/write].
181 The implementation of these are platform specific.
183 * Added WIN32 specific routines of silc_socket_[read/write]
184 to lib/silcutil/win32/silcwin32sockconn.c.
186 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
188 * Added preliminary support for native WIN32 compilation under
189 cygwin (using the -mno-cygwin option for GCC) to the
190 ./configure.in.pre. The --with-win32 now prepares the
191 compilation for native WIN32.
193 * Rewrote the SILC Scheduler interface in the file
194 lib/silcutil/silcschedule.h. The scheduler is now context
195 based and does not have anymore any global static scheduler.
196 Moved the Unix scheduler to the lib/silcutil/unix/ directory
197 and created lib/silcutil/win32 directory for WIN32 based
200 * Added Unix specific network routines to the
201 lib/silcutil/unix/silcunixnet.c and the old
202 lib/silcutil/silcnet.c includes now only generic routines.
204 Added WIN32 specific network routines to the
205 lib/silcutil/win32/silcwin32net.c.
207 * Added Unix specific utility functions from the
208 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
210 * Added WIN32 SILC Scheduler to the file
211 lib/silcutil/win32/silcwin32schedule.c. The code is of course
214 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
216 * Do not handle JOIN notify in the server if the target client
217 is not registered (idata->registered == FALSE). The affected
218 file is silcd/packet_receive.c.
220 * Update the nickrec->founder in event_cumode in the Irssi SILC
221 client. Affected file irssi/src/silc/core/silc-channels.c.
223 * Fixed the CUMODE_CHANGE notify handling in the server when
224 server and router are announcing their clients on channels.
225 Now the mode changes are saved and notified correctly. The
226 affected file is /silcd/packet_receive.c.
228 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
229 They really did not replace the cache entry in the ID Cache.
230 Now they do that. Affected file silcd/idlist.c.
232 * Fixed the KICK notify handling in the Irssi SILC client to
233 update the channel records so that the kicked client does not
234 appear to be on the channel. The affected file is
235 irssi/src/silc/core/silc-channels.c.
237 * Always update the conn->current_channel when executing command
238 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
240 * Fixed the KILL notify handling in Irssi SILC client to remove
241 the killed client on all channels.
243 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
245 * Fixed the silc_parse_command_line to remove extra spaces
246 from the start and end of the arguments. Affected file is
247 lib/silcutil/silcutil.c.
249 * Cancel and free any active protocol in the function
250 silc_server_close_connection. Affected file silcd/server.c.
252 * Cancel and free any active protocol in the function
253 silc_client_close_connction. Affected file is
254 lib/silcclient/client.c.
256 * Do not execute the KILL command for clients that are in
257 history (ie. they are not in the network). Affected file is
260 * Fixed KILL notify handling, client does not crash anymore.
261 Affected file irssi/src/silc/core/silc-channels.c.
263 * Reduced the default packet buffer size from 2048 to 1024 in
264 lib/silccore/silcpacket.c.
266 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
267 counter to the SKE context that is incresed when the SKE library
268 performs async operation outside the library. If the outside
269 process frees the SKE context and FREED status will be set
270 and the library will detect after the sync operation that the
271 libary is freed. The affected files are
272 lib/silcske/silcske[_status].[ch].
274 * Resolve the client entry information in the function
275 silc_client_channel_message to assure that NULL pointer is not
276 passed as client entry to the application. */
278 * Fixed the task timeout calculation to assure that there is
279 never negative timeouts. The affected file is
280 lib/silcutil/silcschedule.c.
282 * Fixed the channel user mode notification sending in server.
283 It was sent point-to-point to the router (or to server by router)
284 but it needs to be destined to a channel. The routines now
285 supports sending the channel user mode notifys to the channels
286 when announcing clients and channels. Affected files are
287 silcd/server.c and silcd/packet_receive.c.
289 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
290 It did not actually replace the old channel entry in the cache.
291 Affected file lib/silcclient/client_notify.c.
293 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
295 * Fixed a possible crash in silc_packet_send_prepare. It now
296 assures always that there is enough space in the buffer and
297 at the tail area of the buffer (for MAC).
299 Fixed the inbound buffer reallocation in silc_packet_read.
300 It was old code and did not handle the reallocation correctly.
303 The affected file is lib/silccore/silcpacket.c.
305 * Fixed buffer overflow in silc_parse_nickname in the file
306 lib/silcutil/silcutil.c.
308 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
310 * make install generates new server keys only if there is not
313 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
315 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
316 Added check that if the NOREPLY is set then we will not send
317 the away message. This avoids infinite loop of away messages
318 if both clients are away. The affected file is
319 lib/silcclient/client_prvmsg.c.
321 * Fixed client crash if /NICK was given without arguments.
322 Affected file lib/silcclient/command.c.
324 * Server does not send the invite list in INVITE command back
325 to the client if the list was not altered. Added this notion
326 to the protocol spec as well. Affected file silcd/command.c.
328 Fixed possible crash in INVITE command by checking the
329 value of silc_server_get_client_route command.
331 * Fixed the INVITE notify type handling. The arguments are now
332 taken in correct order and client does not crash. The affected
333 file is irssi/src/silc/core/silc-channels.c.
335 Removed the "Inviting xxx to channel" message from the
336 client library away and let the application handle it.
337 Affected file lib/silcclient/command.c. Added that message
338 to Irssi SILC client's message formats.
340 * Fixed CMODE command crash in client. It now checks the
341 amount of arguments correctly and does not crash. The affected
342 file is lib/silcclient/command.c.
344 * Do not create new channel automatically in silc_channels_join
345 but check whether the channel by that name already exists.
346 Affected file irssi/silc/core/silc-channels.c.
348 * Do not send the SERVER_SIGNOFF to router if the disconnected
349 entity was the router. Affected file silcd/server.c.
351 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
352 SILC client as it was missing from there.
354 Added the handling of the KICK notify to the Irssi SILC client
355 as it was missing. Added "you have been kicked" message to
356 Irssi SILC client's message modules formats.
358 Added the handing of the KILL notify to the Irssi SILC client
359 as it was missing. Added the kill message module formats
362 The affected file is irssi/src/silc/core/silc-channels.c.
364 * The router did not save the channel mode the server announced.
365 Affected file silcd/packet_receive.c.
367 * Fixed a possible crash in INFO command in server. If the
368 server did not provide the server info it crashed. Affected
369 file silcd/command.c.
371 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
373 * Fixed the GETKEY command in the server to check also the
374 global list. Otherwise the GETKEY would not work correctly
375 in normal SILC server. Affected file silcd/command.c.
377 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
379 * Fixed GETKEY crash, it crashed if the command did not succseed.
381 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
384 is now real and not just an macro interface to GMP.
386 Removed the entire GMP from the source tree and imported new
387 NSS MPI library instead. Reason for removing GMP is that it is
388 extremely large and compiles extremely slow. The NSS MPI
389 is only a few files and compiles in less than 10 seconds.
390 The speed is also about the same as GMP. The MPI is imported
393 If the system has GMP installed we will still use the GMP.
394 If it is not then the NSS MPI will be compiled.
396 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
398 * Merged a long nickname (127 characters long) crash bugfix from
399 Irssi CVS tree. Affected file irssi/src/core/misc.c.
401 * Merged a freed memory reference bugfix from Irssi CVS tree.
402 Affected file irssi/src/core/commands.c.
404 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Added the server's public key sving and verification to the
407 server when performing the SKE. This was missing and the
408 remote server's (or router's) public key was accepted without
409 checking whether we have it previously or trust it at all.
410 Affected file silcd/protocol.c.
412 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
414 * Check in the silc_server_timeout_remote if protocol is active
415 and make sure that the protocol's final callback is called so
416 that all memory if freed. Affected file silcd/server.c.
418 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
420 * silc_server_whois_send_reply crashed the server if the nickname
421 was 127 characters long. Affected file silcd/command.c.
423 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
425 * Added sanity check to the silc_server_new_client. If the hostname
426 is provided inside username then check that the provided hostname
427 really is the same as the resolved one. If the hostname was not
428 resolved then check it from the public key. Affected file is
429 silcd/packet_receive.c.
431 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
432 if the server disconnected us and the connection is not valid
433 anymore. Affected file irssi/src/silc/core/silc-channels.c.
435 * Moved the silc_client_[chmode|chumode|chumode_char] away from
436 the library to the lib/silcutil/silcutil.[ch].
438 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
440 * Close log file after open. Affected file
441 lib/silcutil/silclog.c.
443 * Check whether sock == NULL in silc_client_send_packet and return
444 if it is. Affected file lib/silcclient/silcclient.c.
446 * Check rec->entry == NULL in the Irssi SILC Client before
447 sending the channel message. Affecte file is
448 irssi/src/silc/core/silc-servers.c.
450 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Merged a splitted window bugfix from Irssi CVS tree. The
453 affected file is irssi/src/fe-text/textbuffer-view.c.
455 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
456 It did not print nickname.
458 * Improved the distributions system a bit.
460 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
462 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
463 irssi/src/fe-text/gui-window.c.
465 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
466 to in-active server. The affected file is
467 irssi/src/silc/core/client_ops.c.
469 * Resolve the client in USERS command reply if the entry does
470 not have username resolved. The affected file is
471 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
472 command to WHOIS command to really resolve stuff. The USERS
473 is not used any more in any critical section so WHOIS can
474 be used even though it might be slower than IDENTIFY.
476 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
479 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Changed the protocol API a bit more consistent in the
482 lib/silccore/silcprotocol.[ch].
484 * Changed the following headers to ROBODoc format:
486 lib/silccore/silcpayload.h
487 lib/silccore/silcprotocol.h
488 lib/silccore/silcsockconn.h
490 All core library headers are now formatted.
492 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
494 * Fixed a bug in Irssi SILC client; do not show that you are
495 server/router operator if you really are not. Affected file is
496 irssi/src/silc/core/client_ops.c.
498 * Renamed silc_command_free_payload to silc_command_payload_free.
499 Affected file lib/silccore/silccommand.h
501 * Added silcmath.h to include the prototoypes of various routines
502 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
505 * Changed the following headers to ROBODoc format:
507 lib/silccore/silcchannel.h
508 lib/silccore/silccommand.h
509 lib/silccore/silcid.h
510 lib/silccore/silcidcache.h
511 lib/silccore/silcmode.h
512 lib/silccore/silcnotify.h
513 lib/silccore/silcpacket.h
514 lib/silcmath/silcmath.h
516 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
518 * Added checking to the server code not to start the server if
519 ciphers and stuff are not configured properly. Affected files
520 silcd/serverconfig.[h] and silcd/server.c.
522 * Changed the layout of the header files of the public interfaces
523 in the SILC libraries. The new layout supports ROBODoc
524 documentation tool (and some others) so that it is easy to create
525 a library reference manual. All the other headers and source
526 code must still follow the CodingStyle document. Also source
527 code must not include these ROBODoc stuffs, only the headers.
528 Furthermore, all public interface headers must now be named
529 by using `silc' prefix, example: silcapi.h, silccipher.h.
530 Some files were renamed due to this. All the other headers
531 must not be used as public interfaces. I will update the
532 CodingStyle document later. Changed following headers, so far:
534 lib/silcclient/silcapi.h
535 lib/silccore/silcauth.h
536 lib/silccore/silcprivate.h
537 lib/silccrypt/silcdh.h
539 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Removed silc_client_packet_send_flush from the client library
544 as it is not needed. Affected file lib/silcclient/client.[ch].
546 * Added printing of message of unresolved authentication method
547 to the Irssi SILC client. Added it to the module formats.
548 Removed the same message from the client library.
550 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
552 * Added new distribution feature, DISTLABEL. Every distribution
553 can define own preprocessor label that can be used in the
554 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
555 file distributions, acconfig.h.pre and prepare.
557 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Added Makefile.defines_int to include the actual definitions
560 for Makefile.defines.in. Tested the new distribution system,
561 created distributions and tested installation.
563 * Added AWAY message printing to the Irssi SILC client. Added
564 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
566 * Added SCONNECT command to call the SILC's CONNECT command.
567 Cannot use CONNECT directly since Irssi uses that internally.
568 Affected file irssi/src/silc/core/silc-servers.c.
570 Added ACTION local command. It is same as ME command but takes
571 the channel as mandatory argument.
573 Rewrote some of the Irssi's help files to suite for SILC
576 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
578 * Added Makefile.defines[.in] that should for now on be included
579 in all Makefile.am file in the source tree. That file includes
580 all common compilation definitions for SILC source tree.
582 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
584 * Minor changes to the ./prepare script to change the package
585 name according the distribution name to the configure.in.
587 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
589 * Created new distribution system. Added file `distributions'
590 that defines all the distributions that can be created out of
591 the SILC source tree. The ./prepare script now reads that
592 file to determine how to prepare the distributions. The
593 first argument to the ./prepare is the name of the distribution
594 and second is the version of the distribution. If given
595 without arguments it creates the default (toolkit) distribution
596 with the default version (defined in ./prepare).
598 All Makefile.am files that are subject to the distributions
599 are now named as Makefile.am.pre. These are ./Makefile.am
600 and lib/Makefile.am. Others may be changed later.
602 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
604 * Added invite list, ban list, some key management and connection
605 error message printing to module formats in the Irssi SILC client.
607 * Added new silc_client_set_away_message to set the away message
608 that is back to the person who sent private message. The
609 affected file lib/silcclient/silcapi.h and the
610 lib/silcclient/client_prvmsg.c.
612 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
614 * Fixed the private message sending in the Irssi SILC client,
615 added local command KEY to the Irssi SILC client.
617 Added key management and key agreement message formats to the
618 irssi/src/fe-common/silc/module-formats.[ch].
620 Added USERS (alias WHO) printing, server/router operator
621 indication and LIST command printing to the module formats.
623 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
625 * Fixed channel joining notify handling, cumode notify handling
626 from Irssi SILC client.
628 * Added SILC specific module-formats to the Irssi SILC client so
629 that SILC specific message hilighting, colors etc is possible.
630 Affected file irssi/src/fe-common/silc/module-formats.[ch].
632 Added channel mode, channel user mode, actions, notices,
633 whois and whowas printing to the the module-formats.c.
635 * Fixed a bug in channel deletion in the server. The channel
636 is not left to the cache even if the channel founder auth mode
637 is set when there are no users anymore on the channel. Affected
640 * The silc_net_localhost now resolves the entire hostname including
641 the domain name. Affected file lib/silcutil/silcnet.c.
643 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
645 * Changed the ask_passphrase client operation to be ascynchronous.
646 It has now a completion callback and a context that the
647 application must call after it has got the passphrase from
648 the user. Affected files lib/silcclient/silcapi.h,
649 lib/silcclient/protocol.c, lib/silcclient/command.c and
652 Added SilcAskPassphrase callback that the application calls
653 to deliver the passphrase to the library.
655 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
656 The public key verification and especially a certificate
657 verification is asynchronous procedure.
659 Added new SILC_SKE_STATUS_PENDING status to indicate the
660 request is pending and a callback will be called to finalize
663 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
664 indicate that remote end did not send its public key (or
665 certificate), even though we require it. Added check for this
666 condition in the SKE. This was a security bug, now fixed.
668 Defined new SilcSKEVerifyCbCompletion callback that is called
669 when the verification process is completed.
671 The affected files lib/silcske/silcske_status.h and
672 lib/silcske/silcske.[ch].
674 * Changed the verify_public_key client operation to be async
675 as well. Defined SilcVerifyPublicKey callback that is used to
676 indicate the success of the public key verification process.
678 Changed the server and client to use the new async client
681 * Changed the Irssi SILC client's internal scheduler to be called
682 twice as many times as it used to be. As a result the client
683 should be a bit faster now. Affected file is
684 irssi/src/silc/core/silc-core.c.
686 * Added support to Irssi SILC client of asynchronous public key
687 verification and passphrase inquiry. Affected file is
688 irssi/src/silc/core/silc-core.c.
690 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * Do not say "You have left channel %s" in client library.
693 Moved it to the application. Affected files are
694 lib/silcclient/command.c and silc/client_ops.c.
696 * Fixed silc_client_get_clients. Command context was not
697 duplicated and was freed memory in the callback. Affected
698 file lib/silcclient/idlist.c.
700 * Do not say "you are now talking..." on JOIN command in the
701 client library. The appliation must handle it.
703 * Do not say ".. changed topic to" in command reply in the
704 client libary. The application must handle it.
706 * Fixed TOPIC command sending in the client library.
708 * Fixed a memory leak in silc_client_command_free in the file
709 lib/silcclient/command.c.
711 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
713 * Imported a modified version of Irssi client to the source tree.
714 The Irssi will be used to create a new client called
715 Irssi SILC. Imported to irssi/.
717 Added silc_core_init_finish function to the Irssi. Affected
718 file irssi/configure.in.
720 A lot changes in the Makefile.ams around the irssi tree.
722 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Do not rehash if the new size is same as the old size of the
725 hash table, in the silc_hash_table_rehash*. The affected file
726 lib/silcutil/silchashtable.c.
728 * Replaced hash_table_del_by_context calls from the server
729 (when channel->user_list and client->channels) to the
730 hash_table_del as it is sufficient and faster.
732 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
734 * Added silc_hash_table_list, silc_hash_table_get and the
735 SilcHashTableList structure to provide an alternative way to
736 traverse the hash table. The affected files are
737 lib/silcutil/silchashtable.[ch].
739 * Changed the server's idlist routines to use the hash table
740 routines to optimize the code.
742 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
744 * Replaced the client entry's `channel' list and channel entry's
745 `user_list' list to hash tables for optimized lookup. Changed
746 the code to use the hash table interface around the code.
747 Affected file lib/silcd/idlist.[ch].
749 * Added `auto_rehash' boolean argument to the function
750 silc_hash_table_alloc to indicate whether the hash table should
751 auto-rehash when it thinks is appropriate time. It will
752 increase the hash table size if the there is twice as much
753 entries in the table than the size of the table, and will
754 decrease the size if there are twice as less entries than
755 the size of the table.
757 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
759 * Fixed silc_xxx_get_supported to not crash at some circumstances.
761 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
763 * silc_idcache_purge_by_context deletes the entry now by context
764 as it is supposed to do. Affected file lib/silccore/idcache.c.
766 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
767 client is not anymore valid (WHOWAS givens the info) and not
768 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
770 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
772 * Removed the `data' and `data_len' arguments from the ID Cache
773 interfaces and added `name' argument. ID Cache does not handle
774 anymore the binary data only a names associated with given ID.
776 * When hashing a Client ID with silc_hash_id the entire ID is
777 not hashed anymore, instead only the hash of the Client ID is
778 hashed. This way we can access the Client ID from the cache
779 with Client ID but with the hash of the ID (which is a hash of
780 the nickname) as well without any difference in performance.
782 Added also silc_idcache_find_by_id_one_ext to do one on one
783 searching when we have the actual ID. Added also function
784 silc_hash_client_id_compare. The affected files are
785 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
787 * When hashing the name associated with a ID it is always done
788 in lowercase. This way we can access the cache without worrying
789 about case-sensitivity, even though, for example nicknames are
792 * Fixed a bug in server with channel message sending. It put
793 wrong ID type as destination ID. The affected file
796 * silc_idcache_del_by_context now deletes from all hash tables
797 by context. Affected file lib/silccore/idcache.c.
799 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * Changed the client library to use the new ID Cache interface.
802 Changes around the source tree.
804 * Added silc_hash_table_rehash_ext to rehash with specific
805 hash function. Affected file lib/silcutil/silchashtable.[ch].
807 * Added silc_hash_string_compare to compare two strings in the
808 hash table. Affected file lib/silcutil/silcutil.[ch].
810 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Added new function silc_idcache_del_by_context into the
813 lib/silccore/idcache.[ch].
815 * Changed the server's ID list routines to use the new ID Cache
816 interface. Changes around the source tree.
818 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * Added silc_hash_table_del[_by_context]_ext functions in to the
821 lib/silcutil/silchashtable.[ch].
823 Removed silc_hash_table_find_all* routines and added new
824 silc_hash_table_find_foreach to replace them.
826 Added silc_hash_table_replace_ext function as extended
827 replacing function. Separated the simple hash table interface
828 from the extended hash table interface in the file
829 lib/silcutil/silchashtable.h.
831 * Fixed minor bugs and changed it to use some of the new
832 hash table functions in lib/silccore/idcache.c
834 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Added new function silc_hash_table_find_all to return all keys
837 in the hash table by the specified key. As the hash table is
838 collision resistant it also makes it possible to have several
839 duplicate keys in the hash table. This function may be used to
840 find all of the keys from the hash.
842 Added user_context arguments to the SilcHashFunction,
843 SilcHashCompare and SilcHashDestructor to deliver user specified
846 Added new fuctions silc_hash_table_find[_all]_ext to do
847 extended lookup with specified hash and compare functions and
848 specified user contexts.
850 Added new function silc_hash_table_add_ext to add the key
851 with specified hash function and user context.
853 Added new function silc_hash_table_foreach to traverse all
854 entrys in the hash table. Added SilcHashForeach callback
857 Added new function silc_hash_table_del_by_context to delete
858 the entry only if the context associated with the key matches.
860 Affected files are lib/silcutil/silchashtable.[ch].
862 * Removed silc_hash_[server/client/channel]_id and added just
863 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
864 silc_hash_id_compare to compare two ID's using as the hash table
865 comparison function. Added also silc_hash_data to hash
866 binary data and silc_hash_data_compare to compare it.
868 * Removed silc_idlist_find_client_by_hash as it is not needed
869 anymore. Affected file silcd/idlist.[ch].
871 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
872 to use internally the SilcHashTable. The new ID Cache is a lot
873 faster than the old one. Some of the ID Cache interface was also
874 rewritten and obsolete and stupid functions were removed.
876 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
878 * Added entry_count field to the SilcHashTable to keep the number
879 of the entries in the table. Implemented the function
880 silc_hash_table_rehash. Added new function
881 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
883 Fixed a minor bug in silc_hash_table_free.
885 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
886 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
887 into the lib/silcutil/silcutil.[ch].
889 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
891 * Implemented a collision resistant hash table into the
892 lib/silcutil/silchashtable[ch]. See the header and the source
893 for the SilcHashTable API.
895 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
897 * Merged dotconf version 1.0.2 into lib/dotconf.
899 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
901 * Do not compile anything in lib/silcsim/* if the SIM support
902 is not enabled. The tree should now compile without problems
905 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
907 * Compiled the SILC under cygwin. Compiled and tested briefly
908 without problems. More tests needed. The SIMs didn't compile
911 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
913 * Fixed possible crash in silc_get_username in the
914 lib/silcutil/silcutil.c.
916 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
918 * Fixed a va_arg in silc/client_ops.c.
920 * Oops, RC5 routines were named AES and caused some problems
921 when not using SIM's. Affected file lib/silccrypt/rc5.c.
923 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
925 * Added new SilcIDIP structure into the lib/silccore/id.h and
926 replaced the old `ip' fields from all SILC ID's to that type.
927 This is a step towards IPv6 support.
929 The silc_id_get_len takes now the ID as an extra argument.
930 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
931 both IPv4 and IPv6 based ID's.
933 The affected files are lib/silccore/id.[ch] and other files
934 around the tree using these routines.
936 * Removed the ID length arguments in server from various
937 silc_server_send_notify_* routines -> they are not needed
940 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
942 * Fixed memory leak in silc_encode_pem_file in the file
943 lib/silcutil/silcutil.c.
945 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
947 * Check minor version as well in the SKE. Affected files are
948 silcd/protocol.c and lib/silcclient/protocol.c.
950 * Added --identifier option to the server so that an identifier
951 can be when creating the public key for the server. Affected
952 file is silcd/silcd.c.
954 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
955 lib/silccrypt/silcpkcs.c.
957 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
959 * Register default ciphers and stuff when using -C option with
960 the server. Affected file sildc/silcd.c.
962 * Put back the servers public key filename format, it is better
963 than the new one. For now, the client keys are saved with the
964 new filename format. The affected file silc/client_ops.c.
966 * Implemented the Cipher API for the rest of the ciphers that
967 did not implement it or implemented it the wrong way.
969 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
971 * Register default ciphers and stuff when using the -S option
972 in the client. Affected file silc/silc.c. Same also when
973 creating new key pair with -C option.
975 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
977 * Fixed the silc_verify_public_key client operation function to
978 save the public keys differently. The fingerprint is now
979 used as filename and not the hostname. This way also the
980 client keys are saved uniquely and not with hostnames. The
981 affected file is silc/client_ops.c.
983 * Trimmed the silc_hash_fingerprint function to remove extra
984 whitespaces from the end of the fingerprint. The affected
985 file is lib/silccrypt/silchash.c.
989 * Added silc_cipher_register_default function to register all
990 default ciphers. It can be used when configuration files
991 does not exist and the application does not want any specific
992 ciphers in any specific order.
994 The SilcDList is now used as silc_cipher_list dynamically
995 allocated cipher list. Removed the static list all together
996 and now all ciphers must be allocated to the dynamic list.
997 The silc_cipher_alloc routine was changed to check only the
1000 All silc_cipher_* routines that used to return int returns
1003 The affected files lib/silccrypt/silccrypt.[ch].
1005 * The same thing was done to silc_hash_* as for silc_cipher_*
1006 routines. Affected files lib/silccrypt/silchash.[ch].
1008 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1009 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1010 Added also silc_pkcs_[un]register[_default] functions.
1011 Removed the data_context from the PKCS API.
1013 * Added silc_hmac_register_default function to register default
1014 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1015 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1016 to unregister all hmacs at once.
1018 * Register the default ciphers, hash functions, PKCSs and HMACs
1019 if client's configuration file does not exist. The affected
1022 * The client did not load the hash functions from the SIM
1023 modules at all. Added support for this. Affected file is
1024 silc/clientconfig.c.
1026 * When decoding public key with silc_pkcs_public_key_decode, check
1027 the supported algorithm only if PKCS are registered. Affected
1028 file lib/silccrypt/silcpkcs.c. The same was done with the
1029 silc_pkcs_private_key_decode.
1031 * Fixed the SILC List routines to keep the list always in order.
1032 It used to change the list's order when traversing the list but
1033 not it preserves the order. Affected file lib/trq/silclist.h.
1035 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1037 * Added the client library to use the SilcSocketConnection's
1038 reference counter (by silc_socket_dup) to prevent the bug that
1039 the socket object may be freed underneath async operation.
1041 * The name resolv library checking fixes in the configure.in.pre.
1044 * Created new version of the protocol drafts for future
1045 development. The -03 drafts are the ones that will be changed
1046 in the trunk now and the -02 will remain as they are.
1048 * Send list of CUMODE notifys to the router when announcing
1049 the channel users to the router. Affected file silcd/server.c.
1050 If the router receiving channel founder CUMODE for a channel
1051 that already has channel founder it will send CUMODE notify
1052 to the sender to remove the channel founder rights from the
1053 announced client. Affected file silcd/packet_receive.c.
1055 * The CUMODE notify may now use Server ID as well as the entity
1056 who changes the mode. Updated protocool specs.
1058 * Updated INSTALL and README files.
1060 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1062 * New web pages in the http://silc.pspt.fi. The pages was
1067 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * Implemented the [DenyConnectin] config section in the server.
1070 Added silc_server_config_denied_conn to check whether incoming
1071 connection is denied. Affected file silcd/serverconfig.[ch].
1073 * Do not check the ports when checking the incoming configuration
1074 data if the port is 0, meaning any. Affected file is
1075 silcd/serverconfig.c.
1077 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Fixed buffer overflow in silc_string_compare in the file
1080 lib/silcutil/silcutil.c.
1082 * Fixed double free in silc_server_command_leave in the file
1085 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * Fixed the version checking in the server. Affected file is
1090 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1092 * Fixed the configuration data fetching when accepting new
1093 connections in the server. Affected file silcd/server.c.
1095 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1097 * Added `sender_entry' argument to the function
1098 silc_server_packet_relay_to_channel so that we can check
1099 whether some destination actually belongs to the same route
1100 the sender belongs (ie, we must not resend the packet to the
1101 sender). Affected file silcd/packet_send.[ch].
1103 * Added `servername' field to the SilcClientEntry in the server
1104 to hold the name of the server where client is from. Affected
1105 file is silcd/idlist.h.
1107 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Moved the channel message encrypting in the router betwen
1110 router connections from silc_server_channel_message to the
1111 silc_server_packet_relay_to_channel since we want to check
1112 whether we have anybody channel before encrypting anything.
1113 Affected files silcd/packet_[receive/send].c.
1115 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Fixed the [AdminConnection] server config section to support
1118 multiple entries. Affected file silcd/serverconfig.c.
1120 * Added support into the server to check the validity of the
1121 incoming connection before executing any KE or authentication
1124 * The connection configuration is now saved to the KE and
1125 connection auth protocol contexts and not fetched anymore in
1126 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1128 * The local hosts listenning address and port is also resolved
1129 now when starting the server. We want to have the socket object
1130 to include the real address and port for the listener. Added
1131 new function silc_net_check_local_by_sock into the files
1132 lib/silcutil/silcnet.[ch].
1134 * Fixed a broadcast bug in server -> do not broadcast if we
1137 * Fixed a routing bug. Do not route broadcast packets ever.
1138 Broadcast packets must be processed always and not routed since
1139 they may be destined to some other host than yourself and thus
1140 would get routed without no good reason. Affected file is
1143 * Added function silc_server_config_is_primary_route to check
1144 whether primary router connection has been configured (a router
1145 configuration that we are initiating). If there is not, we
1146 will assume that there is only two routers in the SILC network
1147 and we will use the incoming router connection as our primary
1148 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1150 * Changed the order of the broadcasting. Broadcast _after_ the
1151 packet has been processed not before. Affected file is
1154 * Fixed a [ClientConnection] parsing bug. The port was never
1155 parsed correctly thus resulting to port 0. Affected file
1156 silcd/serverconfig.c.
1158 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1159 argument and did not set the broadcast packet flag. Affected
1160 file silcd/packet_send.c. Fixed same bug in the function
1161 silc_server_send_notify as well.
1163 * If we receive NEW_ID packet for our own ID in the server, ignore
1166 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1170 * Removed the nickname from the Private Message Payload.
1171 Updated the code and the protocol specs.
1173 * Updated protocol specs for submitting to the IETF.
1175 * Tweaked the Random Number Generator a bit. Affected file
1176 lib/silccrypt/silcrng.c. Exported a new function
1177 silc_rng_[global]_add_noise which can be used to add more
1180 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Do not parse packets with different timeout when protocol
1183 is active -> may cause problem with rekey. Affected file
1186 * When server receives signoff notify it must not create
1187 new channel key if the client is on any channels since the
1188 sender of the signoff notify will create it.
1190 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1192 * Added printing of error messages during SKE protocol from the
1193 failure packet sent by server during SKE. Affected file
1196 * Removed the client's failure_callback handling with timeout
1197 and handle it immediately when received.
1199 * The SKE library returned wrong type in SUCCESS and FAILURE
1200 packets. They must be 32 bit MSB not 16 bit MSB.
1202 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1204 * Ok, rewrote the logic of the re-key and now it seems to work.
1205 I tested it on high traffic with frequent re-keys without
1206 problems. Added hmac_receive (and renamed hmac to hmac_send)
1207 in SilcClientConnection in lib/silcclient/client.h and
1208 in SilcIDListData in silcd/idlist.h. Also, removed the
1209 SilcPacketParserContext's cipher and hmac fields as they are
1210 not needed anymore and actually caused some problems when
1211 the ciphers and hmac's changed underneath the packet parser.
1213 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1215 * If re-key protocol is active then process the incoming packets
1216 synchronously since we must assure that icoming packets encrypted
1217 with the old key is processed before the new keys is set to
1218 use. This is true other packets than for REKEY packets.
1219 Affected file silcd/server.c. The same was done to client library
1220 as well, affected file lib/silcclient/client.c.
1222 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1224 * Fixed bug in client and server to accept the force send if
1225 the packet is send from silc_[server/client]_packet_process
1226 function. Otherwise the packets are never delivered, oops.
1228 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Disable force sending of packets when REKEY protocol is active.
1231 We must assure that no packet is sent directly when rekey is
1232 performed. All packets must be sent through packet queue.
1233 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1234 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1235 function is silc_[server/client]_packet_send_real to check
1238 * Replaced the SIM paths from example config files to
1239 /usr/local/modules. Also, make install creates now
1240 /usr/local/silc/logs directory to hold all the SILC server
1243 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Made the configure.in.pre work on Solaris. Patch by salo.
1247 * Made all ciphers compatible with non-x86 machines. Defined
1248 CBC mode macros into lib/silccrypt/ciphers_def.h.
1250 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1252 * Fixed the make install.
1254 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1256 * When MAC computation fails the silc_packet_decrypt returned 0
1257 even though it was supposed to return -1. Fixed this. The
1258 affected file is lib/silccore/silcpacket.c.
1260 * Do not replace the config files in /etc/silc (in make install)
1261 if they already exist. Affected file ./Makefile.am.
1263 * Do not send re-key packets immediately but through packet queue.
1264 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1266 * Changed silc_net_check_host_by_sock to return FALSE if the
1267 IP/DNS could not be resolved. Though, it returns the IP address
1268 now even if it could not resolve it (but returns also FALSE).
1269 Affected file lib/silcutil/silcnet.[ch].
1271 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1273 * Added silc_pkcs_decode_identifier to decode the public key's
1274 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1275 Added also silc_pkcs_free_identifier. Added also new context
1276 SilcPublicKeyIdentifier.
1278 * Added -S option to the silc client. It is used to dump the
1279 contents of the specified public key file.
1281 * Changed the PKCS api to return the public key length when
1282 setting the public key.
1284 * Fixed a fatal bug in the public and private key file loading.
1285 Affected file lib/silccrypt/silcpkcs.c.
1287 * Execute the packet parsing for client with zero (0) timeout
1288 if the protocol is active. Affected file silcd/server.c.
1290 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * Made the key generation options to the silcd program. Added
1293 -C option, equivalent to client's option.
1295 * Added new [ServerKeys] config section to the server. It
1296 configures the server's public and private key.
1298 * Defined generic Public Key Payload into the protocol
1299 specification to send specific type of public keys and
1302 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1303 public key or certificate.
1305 * Implemented the GETKEY command to the server and to the
1306 client library and on user interface.
1308 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Made preliminary `make install' work.
1312 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1314 * Added SilcServerRekey context into silcd/idlist.h.
1316 * Added the PFS support as defined in the specification to the
1317 SKE protocol. Affected files lib/silcske/*.c.
1319 * Added `ske_group' field to the SilcServerRekey context to hold
1320 the number of the SKE group that is used with PFS in re-key.
1321 Affected file silcd/idlist.h.
1323 * Added PFS re-key support to the server. Affected file is
1326 * Added silc_protocol_cancel to cancel execution of the next
1327 state of the protocol. Affected file is
1328 lib/silccore/silcprotocol.[ch].
1330 * Added the re-key support with and without PFS to the client
1331 library. Re-key is performed once in an hour, by default.
1333 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1334 Added silc_client_rekey_callback and silc_client_rekey_final.
1335 Affected files are lib/silcclient/protocol.[ch] and
1336 lib/silcclient/client.[ch].
1338 * Removed the `hmac_key' and `hmac_key_len' fields from the
1339 SilcClientConnection structure; not needed. Affected file is
1340 lib/silcclient/client.h.
1344 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * Do not ask whether user wants to use the negotiated private key
1347 for private messages, just use it. Affected file is
1348 silc/local_command.c.
1350 * Added `send_enc_key' and `enc_key_len' fields to the
1351 SilcIDListData structure since they are needed in the re-key
1352 phase. Affected file is silcd/idlist.[ch].
1354 * Implemented the simple re-key protocol into the server.
1355 Affected files silcd/server.c and silcd/protocol.[ch]. The
1356 re-key will be performed once in an hour, by default.
1358 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1359 Added silc_server_rekey, silc_server_rekey_callback and
1360 silc_server_rekey_final.
1362 * Removed Tunneled flag from the protocol. Updated the code
1363 and the specifications.
1365 * Adde `pfs' field to the SilcIDListData to indicate whether
1366 the PFS is to be performed in the re-key. Affected file is
1369 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1371 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1372 int64 of at least the xintXX size. If void * is less that 4
1373 bytes uint32 * will be used. Defined bool as boolean.
1375 * Changed _ALL_ unsigned long and unsigned int to uint32,
1376 unsgined short to uint16 in the source tree.
1378 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1379 not handle clients that has entry->data.registered == FALSE.
1380 They are not in the network anymore. Affected file is
1383 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Implemented the sending of the SERVER_SIGNOFF notify in the
1386 server. Affected file is silcd/server.c.
1388 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1389 Added also silc_notify_payload_encode_args into the
1390 lib/silccore/silcnotify.[ch].
1392 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1393 Affected file silcd/packet_receive.c.
1395 * Implemented the SERVER_SIGNOFF notify handling in the client
1396 library. Affected file lib/silcclient/client_notify.c. Also,
1397 implemnted the printing of the SERVER_SIGNOFF info to the
1398 application. Affected file silc/client_ops.c.
1400 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1401 if the deleting was successful. Affected file silcd/idlist.[ch].
1403 * Added support for public key authentication in the connection
1404 authentication protocol in the client library. Affected file
1405 lib/silcclient/protocol.c.
1407 * Changed the server's silc_idlist_get_clients_by_* interface
1408 to support already allocated array so that new entries may be
1409 added to pre-allocated array. Affected file silcd/idlist.[ch].
1410 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1411 and command replies.
1413 * All command reply functions in the server now calls the
1414 pending command callback even if error occured. This way the
1415 error will be delivered to the client as well. Affected files
1416 silcd/command.c and silcd/command_reply.c.
1418 * Fixed INFO command to return local server's info if no server
1419 was provided. Affected file lib/silcclient/command.c.
1421 * Removed RESTART command for good. Updated the code and the
1424 * Rewrote parts of the task system. It is a bit simpler now.
1425 Removed unsued task priorities. The affected files are
1426 lib/silcutil/silctask.[ch].
1428 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1430 * Moved the USERS printing from the library to the application.
1431 Affected files lib/silcclient/command.c and silc/client_ops.c.
1433 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1437 * Added channel key re-key support. The re-key is perfomed
1438 only by the router and is done once in an hour. Added `rekey'
1439 field to the SilcChannelEntry in the server. Affected files
1440 silcd/server.c and silcd/idlist.h.
1442 * Added silc_task_unregister_by_context into the file
1443 lib/silcutil/silctask.[ch].
1445 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Added SILC_UMODE_GONE mode to indicate when the client is not
1448 present in the SILC network. Added also support to the local
1449 command AWAY that will set this mode. Added support of showing
1450 "xxx is gone" in WHOIS command. The USERS command shows the
1451 gone status as well.
1453 * Fixed setting server and router operator privileges in the
1454 server's UMODE command. Affected file silcd/command.c.
1456 * Merged the SKE KE1 and KE2 payloads into one payload. The
1457 new KE payload is equivalent to the old KE2 payload.
1459 Cleaned up the SKE Start Payload parsing. It now uses the
1460 simple buffer unformatting to do the parsing. A lot faster
1463 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1464 to the SKE that is used to indicate whether both of the SKE
1465 parties should perform authentication. By default only the
1466 responder performs authentication. By setting this flag also
1467 the initiator must do authentication. By default it is unset
1468 since in normal SKE case, client to server connection, only
1469 the responder should do authentication. When doing SKE between
1470 two clients both should perform authentication. Updated the
1471 code and the protocol specs.
1473 * A little fix to IDENTIFY command in the server. Search the
1474 client first by hash not nickname. Affected file is
1477 * Fixed the silc_client_close_connection to support closing
1478 the client to client connections wihtout deleting too much
1479 data. Affected file lib/silcclient/client.c.
1481 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1482 are received if protocol used to be active but is not anymore
1483 the application would crash due to NULL pointer dereference.
1484 Affected files silcd/server.c and lib/silcclient/client.c.
1486 * Added `hash' field to the SilcClientConnection to include
1487 the hash function negotiated in the SKE protocol.
1489 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1490 to set the channel founder authentication data. A client can
1491 claim the founder rights later by providing the authentication
1492 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1493 This way the channel founder can regain the channel founder
1494 privileges even it is left the channel. This works only on
1495 local server and the client must be connected to the same
1496 server to be able to regain the founder rights. Updated the
1497 protocol specs accordingly.
1499 Added support to the CMODE command in the client to set the
1500 founder auth data. Read the README to see how to set it.
1502 Added support to the CUMODE command to claim the founder
1503 rights. Read the README to see how to do it.
1505 Added support for the founder authentication to the Channel
1506 Entry in the server. Affected file silcd/idlist.h.
1508 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1509 server's CMODE command. Affected file silcd/command.c.
1511 * Added the following new functions into lib/silccore/silcauth.[ch]:
1512 silc_auth_get_method and silc_auth_get_data.
1514 * The server now saves the remote hosts public key to the
1515 SilcIDListData pointer. Affected file silcd/protocol.c.
1517 * The normal server now does not remove the channel entry from
1518 the cache if the founder authentication data is set. It used
1519 to remove it if the founder was the last one on the channel on
1520 the server and left the channel. The auth data is saved and
1521 if the channel is re-joined later the old entry is used with
1522 the old auth data. Affected files silcd/command_reply.c and
1525 * Removed the `pkcs' field from the SilcIDListData structure
1526 in the server; it is not used. Affected file silcd/idlist.h.
1528 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Fixed packet processing on slow links. Partial packets were
1531 never re-processed because the incoming data buffer was cleared
1532 by the application. Application must not directly clear the
1533 sock->inbuf, the packet processing routines handle it. Fixed
1534 this in client library and in server.
1536 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1538 * Fixed the WHOIS and IDENTIFY send reply function to really
1539 check whether to send list or just one entry. Affected file
1542 * Cleaned up the LEAVE command's channel key distribution. The
1543 affected file silcd/command.c.
1545 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1546 can enforce the channel mode as well. In that case the ID
1547 includes the ID of the server. The code now enforces the
1548 mode change if the router have different mode than the server.
1550 * The notify client operation with CMODE_CHANGE notify can now
1551 return NULL client_entry pointer if the CMODE was not changed
1552 by client. Application must check for this.
1554 * Added <Server ID> argument to INFO command to support server
1555 info fetching by Server ID.
1557 * Added silc_server_announce_get_channel_users to get assembled
1558 packets of channel users of the specified channel. Affected
1559 file silcd/server.[ch].
1561 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1562 was freed underneath the ID Cache.
1564 * Re-announce clients when the server received CHANNEL_CHANGE
1565 notify from the router. Affected file silcd/packet_send.c.
1567 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1569 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1570 crashed since it did not handle the fact that there is no cipher
1571 called "3" and didn't check the error condition. Now fixed.
1573 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1574 flag. It can be used to send message requests.
1576 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Implemented the RESTART command in the client.
1580 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1581 notice type messages. Added notice printing to the user
1584 * The channel keys are not re-generated if the channel's mode
1585 is PRIVKEY, ie private key on the channel exists. Affected
1586 files silcd/server.c and silcd/command.c.
1588 * Fixed a little bug in channel message delivery when channel
1589 private keys are set in the server. Affected file is
1590 silcd/packet_send.c.
1592 * Changed the setting on channel->on_channel = TRUE from the
1593 silc_client_save_channel_key to the JOIN command reply. The
1594 key payload is not received if the private channel key is set.
1595 Affected file lib/silcclient/command_reply.c and the
1596 lib/silcclient/client_channel.c.
1598 * When the CMODE_CHANGE notify is sent and the channel private
1599 key mode is removed the channel key must be re-generated in
1600 other cells as well. Added this support for the router in the
1601 silcd/packet_receive.c.
1603 * Added new local command NOTICE to send notice message on
1604 channel. Affected file silc/local_command.[ch].
1606 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * Added new local command ME to the client. It is used to send
1609 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1610 some action. Affected file silc/local_command.[ch].
1612 * Changed channel_message and private_message client operations
1613 to deliver the message flags to the application. Added also
1614 the `flags' arguments to the silc_client_send_channel_message
1615 and silc_client_send_private_message functions. Affected file
1618 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1620 * Redefined the Private Message Payload to support private message
1621 keys and to support the new private message flags. Updated
1622 the protocol specs. Flags makes it possible to have for example
1623 CTCP style messages.
1625 * Added new type SilcPrivateMessagePayload and defined an API
1626 for it in the lib/silcclient/silcprivate.[ch].
1628 * Tested private message private keys successfully. Tested the
1629 private message key set, unset and list commands with the new
1632 * Redefined the Channel Message Payload to include the channel
1633 message flags (equal with private message flags) to support
1634 for example CTCP style messages.
1636 * Defined some of the message (for channel and private message)
1637 flags. Updated the protocol specs and added the flags to the
1638 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1640 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * Added SilcKeyAgreementStatus type to the key agreement routines
1643 to indicate the current status and error if one occured.
1644 The status types are defined in the lib/silcclient/silcapi.h.
1646 * Added new local command KEY that is used to set and unset private
1647 keys for channels, set and unset private keys for private messages
1648 with remote clients and to send key agreement requests and
1649 negotiate the key agreement protocol with remote client. The
1650 key agreement is supported only to negotiate private message keys,
1651 it currently cannot be used to negotiate private keys for channels,
1652 as it is not convenient for that purpose.
1654 * Fixed a minor pending callback setting bug in the function
1655 silc_client_get_client_by_id_resolve, now the function works.
1656 Affected file lib/silcclient/idlist.c.
1658 * Added function silc_net_get_local_port to get local bound
1659 port by socket. Added to lib/silcutil/silcnet.[ch].
1661 * Added `sockets' and `sockets_count' fields to the SilcClient
1662 object. They hold the sockets of the listenning sockets in
1663 the client. Listenning sockets may be for example the key
1664 agreement server. Affected file lib/silcclient/client.[ch].
1665 Added functions the silc_client_add_socket and the
1666 silc_client_del_socket. They are exported to the application
1669 * Added ~./silc/clientkeys to support other client's public keys.
1671 * Renamed verify_server_key client operation to verify_public_key
1672 and added one argument to indicate the type of the connection
1673 (server, client etc.).
1675 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Added silc_server_connection_auth_request to handle the
1678 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1679 silcd/packet_receive.[ch].
1681 * Added silc_server_send_connection_auth_request into the
1682 silcd/packet_send.c to send the connection auth request packet.
1684 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1687 * Fixed the public key authentication in responder side in the
1688 server. The `auth_data' pointer includes the SilcPublicKey
1689 not the path to the public key. Affected file silcd/protocol.c.
1691 * Implemented the public key authentication in the initiator side
1692 in the server. Affected file silcd/protocol.c.
1694 * Removed the [RedirectClient] config section from the server
1695 configuration. Is not needed and I don't want to implement it.
1697 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1699 * Cleaned up the CMODE command in the server. It now works
1700 correctly and supports all the modes defined in the protocol.
1701 Affected file is silcd/command.c.
1703 * Added `hmac_name' field to the SilcChannelEntry in the server
1704 to hold the default HMAC of the channel. It can be set when
1705 creating the channel (with JOIN command). Affected files
1708 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1709 type to indicate the change of the current cipher and hmac
1710 on the channel. Client can safely ignore the <cipher> argument
1711 (if it chooses to do so) since the CHANNEL_KEY packet will
1712 force the channel key change anyway. The <hmac> argument is
1713 important since the client is responsible of setting the new
1714 HMAC and the hmac key into use.
1716 * Fixed the CMODE command in the client library as well.
1718 * Tested CMODE command in router environment successfully.
1720 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1722 * Show the version of the remote client (or server) when connecting
1723 to the server. It is logged to the log file. Affected file
1724 is silcd/protocol.c.
1726 * Fixed the KILLED notify handling in the client library. The
1727 client must be removed from all channels when receiving the
1730 Also, do not remove the client entry when giving the KILL
1731 command but when the KILLED notify is received.
1733 * Removed silc_idlist_find_client_by_nickname from the server.
1734 Not needed anymore. Affected files silcd/idlist.[ch].
1736 * Implemented the CHANNEL_CHANGE notify type handling to the
1737 server. Affected file silcd/server.c.
1741 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1743 * Added silc_server_send_notify_invite to send the INVITE
1744 notify between routers.
1746 * Implemented the INVITE command correctly to the server.
1748 * Implemented the INVITE notify type handling in the server.
1750 * Implemented the INVITE command to the client library and on the
1753 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1755 * Added function silc_server_get_client_resolve to find the
1756 client entry by ID from all ID lists and then resolve it
1757 (using WHOIS) if it cannot be found. Affected file is
1760 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Implemented the BAN command to the client library.
1764 * The JOIN command in the server now checks the invite list
1767 * Changed the silc_command_reply_payload_encode_va and the
1768 silc_command_payload_encode_va to support that if argument is
1769 NULL it ignores and checks the next argument. Affected file
1770 lib/silccore/silccommand.c.
1772 * Added silc_server_send_notify_ban to send the BAN notify
1773 type between routers.
1775 * Chaned the silc_notify_payload_encode to support that if
1776 argument is NULL it ignores and checks the next argument.
1777 Affected file lib/silccore/silcnotify.c.
1779 * Tested ban lists in router environment successfully.
1781 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1783 * Implemented BAN command to the server, in silcd/command.[ch].
1785 * Removed the BAN and INVITE_LIST modes from the CMODE command
1788 * Added function silc_string_match to regex match two strings.
1789 Affected files lib/silcutil/silcutil.[ch].
1791 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Redefined parts of the SilcChannelEntry in the server to support
1794 the new ban and invite lists.
1796 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Redefined the INVITE command. The same command can be used to
1799 invite individuals to the channel but also to manage the invite
1800 list of the channel (to add to and remove from the invite list).
1801 Updated the protocol specs.
1803 * Added new command SILC_COMMAND_BAN that can be used to manage
1804 the ban list of the channel. Updated the protocol specs.
1806 * Removed the channel modes: the SILC_CMODE_BAN and the
1807 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1808 in the CMODE command. The equivalent features are now available
1809 using INVITE and BAN commands. Updated the protocol specs.
1811 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1812 in the network about change in the current ban list. The notify
1813 type is not used by the client.
1815 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1816 support the invite lists.
1818 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1820 * Added new function silc_string_regexify that converts string
1821 including wildcard characters into regex string that can
1822 be used by the GNU regex library. Added into the file
1823 lib/silcutil/silcutil.[ch].
1825 Added silc_string_regex_combine to combine to regex strings
1826 into one so that they can be used as one regex string by
1827 the GNU regex library. Added into the file
1828 lib/silcutil/silcutil.[ch].
1830 Added silc_string_regex_match to match two strings. It returns
1831 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1833 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1835 * Imported GNU regex to the soruce tree into lib/contrib.
1836 Fixed some compiler warning from the regex.c.
1838 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1840 * Fixed MOTD command in the server to work in router environment.
1842 * Fixed the MOTD command in the client library to support
1843 the server argument in the command.
1845 * Added `nickname_len' argument to the silc_idlist_add_client
1846 in the server, as the `nickname' argument may be binary data
1849 * Added silc_idlist_get_channels to return all channels from
1852 * Implemented LIST command to the server. Affected file is
1855 * Implemented the LIST command to the client library and on the
1858 * Added [<user count>] argument to the LIST command reply.
1859 With private channels the user count is not shown.
1861 * Updated TODO and README.
1863 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1865 * The client entry's data.registered must be TRUE even with
1866 global client entry on global client list. The data.registered
1867 is used to check whether the client is anymore in the network,
1868 for example with WHOWAS command so it must be valid.
1870 * Fixed the WHOWAS command in the server. It now actually works
1871 in router environment. Added function into silcd/command_reply.c
1872 silc_server_command_reply_whowas_save.
1874 * Added silc_idlist_purge function to the silcd/idlist.c
1875 to periodically purge the ID Cache.
1877 * Fixed INFO command in the server. It works now in router
1878 environment. Added <server name> argument to the INFO command
1879 reply. Updated the protocol specs.
1881 * Fixed minor bug in silc_idcache_purge to not purge if the
1882 expire value is zero.
1884 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1885 they were buggy because of the WHOWAS information.
1887 * Fixed local command MSG to handle the async resolving of
1888 the remote client properly. It used to fail the first MSG.
1889 Affected file silc/local_command.c.
1891 * Added `data_len' field to SilcIDCache context.
1893 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1895 * Update TODO. Todo in commands in the server.
1897 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1899 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1900 used by routers as broadcast packet to inform other routers
1901 about the changed user mode.
1903 Implemented the notify handling in the server. Affected file is
1904 silcd/packet_receive.c. Added the function
1905 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1907 * Added new generic Channel Payload and deprecated the New Channel
1908 Payload. The New Channel Payload is now the generic Channel
1911 * Added new argument `mode' to the silc_server_send_new_channel
1912 as it is required in the Channel Payload now.
1914 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1915 and created a new and real SilChannelPayload to represent the
1916 new generic Channel Payload. Implemented the encode/decode
1917 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1919 * Added silc_server_get_client_channel_list to return the list
1920 of channels the client has joined for WHOIS command reply.
1921 Affected file silcd/server.[ch].
1923 * Implemented the channel list sending in the WHOIS command reply
1924 in server and in the client.
1926 Implemented the channel list displaying on the user interface
1927 as well. Affected file silc/client_ops.c.
1929 * Added silc_channel_payload_parse_list to parse list of Channel
1930 Payloads. It returns SilcDList list of SilcChannelPayloads.
1931 Client for example can use this function to parse the list of
1932 channels it receives in the WHOIS command reply. The caller
1933 must free the list by calling silc_channel_payload_list_free.
1934 Affected files lib/silccore/silcchannel.[ch].
1936 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * Added one new argument <user mode> to the WHOIS command reply
1939 to return the mode of the user in SILC. Updated the protocol
1942 Implemented it to the server and client.
1944 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1946 * Fixed the mode printing on the user interface on joining.
1947 Affected file silc/client_ops.c.
1949 * Implemented the UMODE command and user modes in general to the
1950 client library and to the user interface.
1952 * Implemented the UMODE command to the server.
1954 * The server now sends UNKNOWN_COMMAND error status if client sends
1955 unknown command. Affected file silcd/command.c.
1957 * All server commands now handle the command identifier the right
1958 way when sending the command reply to the client. The client can
1959 use to identify the command replies with the identifier.
1961 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Added silc_server_get_client_route to resolve the route to
1964 the client indicated by the client ID. Affected file is
1967 * Added silc_server_relay_packet as general function to relay
1968 packet to arbitrary destination. This deprecates functions
1969 like _send_private_message_key, _relay_notify etc. Affected
1970 file is silcd/packet_send.[ch].
1972 Removed silc_server_send_key_agreement,
1973 silc_server_send_private_message_key and
1974 silc_server_packet_relay_notify functions from the file
1975 silcd/packet_send.[ch].
1979 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1980 server. Affected file silcd/packet_receive.[ch].
1982 * Implemented the KILL command to the client. Implemented the
1983 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1984 Affected files lib/silcclient/command[_reply].c and
1985 lib/silcclient/client_notify.c. Implemented the KILL notify
1986 printing in the user inteface.
1988 * Fixed a lot silc_parse_nick memory leaks from the client
1989 library in the file lib/silcclient/command.c.
1991 * Changed the silc_server_send_notify_on_channels's `sender'
1992 argument from SilcSocketConnection to SilcClientEntry to
1993 check the sender as entry and not as connection object and not
1994 to send to the client provided as argument. The affected file
1995 is silcd/packet_send.[ch].
1997 * The notify packets that are destined directly to the client used
1998 to not to be processed by the server. Now changed that and the
1999 server processes all notify packets. After relaying the packet
2000 to the client the notify packet is processed in the server.
2002 * The silc_server_free_client_data now checks whether there is
2003 pending outgoing traffic for the client and purges the data to
2004 the network before removing the client entry.
2006 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2008 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2009 an client is killed from the SILC Network. Updated the protocol
2012 Added new function silc_server_send_notify_killed to the
2013 silcd/packet_send.[ch].
2015 * Added function silc_server_packet_relay_notify to relay notify
2016 packets that are destined directly to a client. In this case
2017 the server does not process the notify packets but merely relays
2018 it to the client. Affected file silcd/packet_send.[ch].
2020 Added also silc_server_packet_process_relay_notify to check
2021 whereto relay the notify. Affected file is
2022 silcd/packet_receive.[ch].
2024 * Implemented the KILL command to the server.
2028 * Added the backup schema desgined last fall to the protocol
2029 specs for everyone to see. The specification is in the
2030 *-spec-xx.txt draft and the packet type definitions for the
2031 backup routers is in *-pp-xx.txt draft. Thusly, added also
2032 new packet type SILC_PACKET_CELL_ROUTERS.
2034 * A big security problem in the implementation discovered. The
2035 signoff of an client did not cause new channel key generation
2036 which it of course should've done. The channel keys must be
2037 always re-generated when client leaves (or signoffs) the channel.
2038 The silc_server_remove_from_channels funtion now handles
2039 the channel key re-generation.
2041 * Added `sender' argument to the silc_server_send_notify_on_channels
2042 to not to send the client provided as argument. Affected file
2043 silcd/packet_send.[ch].
2045 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2047 * Implemented OPER and SILCOPER commands into the server and
2050 * Added silc_auth_verify and silc_auth_verify_data to verify
2051 the authentication directly from the authentication payload.
2052 It supports verifying both passphrase and public key based
2053 authentication. Affected file lib/silccore/silcauth.[ch].
2055 * Added `hash' field to the SilcIDListData structure. It is the
2056 hash negotiated in the SKE protocol. Affected file is
2059 * Slight redesigning of the SilcAuthPayload handling routines.
2060 Do not send SilcPKCS but SilcPublicKey as argument.
2062 * Implemented the public key authentication support to the
2063 serverconfig. The public key is loaded from the provided path
2064 and saved as authentication data to void * pointer. Thus,
2065 changed the unsigned char *auth_data to void *auth_data;
2067 * Fixed SHUTDOWN command to send the reply before the server
2068 is shutdown. :) Affected file silcd/command.c.
2070 * Fixed fatal bug in CONNECT command. The hostname was invalid
2071 memory and server crashed. Affected file silcd/command.c.
2073 * Fixed fatal bug in CLOSE command. The server_entry became
2074 invalid but was referenced later in the command. Affected file
2077 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Fixed fatal bug in failure packet handling. Server ignored
2080 the failure and thus crashed when it came.
2084 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2086 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2087 that the command may be executed only once in (about) 2 seconds.
2088 The old SILC_CF_LAG flag is same but allows command bursts up
2089 to five before limiting.
2091 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2092 server code. Various commands now includes the CF_LAG_STRICT
2093 flag to disallow any kind of miss-use of the command.
2095 * Fixed the silc_buffer_unformat to not to allocate any data
2096 if the length of the data is zero. It used to allocate the
2097 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2099 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2101 * Changed the format of AdminConnection configuration section
2102 in the server. Added username of the admin to the format.
2103 Affected files silcd/serverconfig.[ch].
2105 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2106 to return admin configuration data by host, username and/or
2109 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2111 * Implemented WHOWAS command to the server. Added the functions:
2113 silc_server_command_whowas_parse,
2114 silc_server_command_whowas_send_reply,
2115 silc_server_command_whowas_from_client and
2116 silc_server_command_whowas_from_server
2118 * Added <Client ID> argument to the WHOWAS command reply. Updated
2119 the protocol specs accordingly.
2121 * Implemented WHOWAS command and command_reply to the client
2124 Implemented the WHOWAS printing on the user interface.
2126 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2128 * Added new argument to the WHOWAS command reply, the real name.
2129 It is an optional argument. Updated the protocol specs.
2131 * Added SilcIDCacheDestructor callback that is registered when
2132 the SilcIDCache is allocated. The callback is called when
2133 an cache entry in the ID Cache expires, or is purged from the
2134 cache. Added into lib/silccore/idcache.[ch].
2136 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2137 to destruct the client entries when the cache entry expires.
2138 Other ID Cache's in server and in the client library ignores
2141 * If the ID Cache entry's `expire' field is zero then the entry
2142 never expires. Added boolean `expire' argument to the
2143 silc_idcache_add function in the lib/silccore/idcache.[ch].
2144 If it is TRUE the default expiry value is used.
2146 * Added silc_server_free_client_data_timeout that is registered
2147 when client disconnects. By default for 5 minutes we preserve
2148 the client entry for history - for WHOWAS command.
2150 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2152 * Added support to the server to enforce that commands are not
2153 executed more than once in 2 seconds. If server receives
2154 commands from client more frequently, timeout is registered
2155 to process the commands. Affected file silcd/command.c.
2156 Added new function silc_server_command_process_timeout.
2158 * Changed NICK_NOTIFY handling in client library to check that
2159 if the client's nickname was changed, so there is no need to
2160 resolve anything from the server.
2162 * Removed error printing from the WHOIS and IDENTIFY commands.
2163 If error occurs then it is ignored silently in the client library.
2164 The application, however, may map the received error to
2165 human readable error string. The application currently maps
2166 the NO_SUCH_NICKNAME error to string.
2168 * Made the command status message public to the application. Moved
2169 them from lib/silcclient/command_reply.c to
2170 lib/silcclient/command_reply.h. The application can map the
2171 received command status to the string with the
2172 silc_client_command_status_message function.
2174 * Added check to the server to check that client's ID is same
2175 as the Source ID in the packet the client sent. They must
2178 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2180 * Added dist-bzip hook to the Makefile.am to make bzip2
2181 compressed distributions.
2183 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2185 * Server now enforces the maximum length for the nickname and
2186 the channel as protocol specification dictates. 128 bytes for
2187 nickname and 256 bytes for channel name.
2189 * Moved the WHOIS printing to the application. The client libary
2190 does not print out the WHOIS information anymore, the application
2191 must do it. Renamed silc_client_command_reply_whois_print to
2192 the silc_client_command_reply_whois_save.
2194 The client's idle time is also sent to the application now, and
2195 the idle is shown on screen.
2197 * Added silc_client_command_reply_identify_save to save the
2198 received IDENTIFY entries.
2200 * Do not check for channel private keys in message sending and
2201 reception if the channel does not have the PRIVKEY mode set.
2202 Affected file lib/silclient/client_channel.c.
2204 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2207 just surfaced after chaning the JOIN procedure.
2209 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Added silc_client_get_clients_by_list to get client entries
2212 from Client ID list, that is returned for example by JOIN
2213 and USERS command replies. The application should use this
2214 function for example when JOIN command reply is received to
2215 resolve the clients already on the channel (library does not
2216 do that anymore as USERS command reply is not used in the JOIN
2217 procedure anymore). Affected files lib/silcclient/silcapi.h and
2218 lib/silcclient/idlist.c.
2220 * JOIN command reply and USERS command reply returns now SilcBuffer
2221 pointers instead of unsigned char pointers when returning
2222 the client list and mode list.
2224 * Added <Client ID> argument to the JOIN command reply, mainly
2225 for the server to identify for which client the command was
2226 originally sent. Updated protocol specs accordingly.
2228 * Added SilcDlist private_key pointer to the SilcChannelEntry
2229 in the client to support the channel private keys. Affected
2230 file is lib/silcclient/idlist.h.
2232 * Added SilcChannelPrivateKey argument to the function
2233 silc_client_send_channel_message so that application can choose
2234 to use specific private ke if it wants to. If it is not provided,
2235 the normal channel key is used, unless private keys are set.
2236 In this case the first (key that was added first) is used
2237 as the encryption key.
2239 * Implemented the support for channel private key handling.
2240 Implemented the following functions:
2242 silc_client_add_channel_private_key,
2243 silc_client_del_channel_private_keys,
2244 silc_client_del_channel_private_key,
2245 silc_client_list_channel_private_keys and
2246 silc_client_free_channel_private_keys
2248 Affected file lib/silcclient/client_channel.c.
2250 * Added the support for the private keys in the channel message
2251 sending and encryption and in the message reception and
2252 decryption. Affected funtions are
2253 silc_client_send_channel_message and silc_client_channel_message.
2255 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Added SKE's key verify callback to the client library's
2258 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2260 * Removed the statement that server (or router) must send USERS
2261 command reply when joining to the channel so that the client
2262 knows who are on the channel. Instead, the client list and
2263 client's mode list is now sent in the JOIN command reply to the
2264 client who joined channel. This is better solution.
2266 * Added function silc_server_get_users_on_channel and function
2267 silc_server_save_users_on_channel to the silcd/server.[ch].
2269 * Removed function silc_server_command_send_users from the
2272 * Do not show topic on the client library anymore. The topic is
2273 sent in the command reply notify to the application and the
2274 application must show the topic now.
2276 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Added client searching by nickname hash into the IDENTIFY and
2279 WHOIS commands in the server as they were clearly missing from
2280 them. Affected file is silcd/command.c.
2282 * Fixed a bug in private message receiving in the client library.
2283 The remote ID was freed and it wasn't supposed, now it is
2286 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2288 * Minor fix to the channel payload; allocate the data area, as it
2289 needs to be of specific length.
2291 * If the key agreement port is zero then the operating
2292 system will define the bound port. Affected files are
2293 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2295 * Added new function silc_channel_payload_decrypt into the file
2296 lib/silccore/silcchannel.[ch].
2298 * Moved the channel message etc, check from silc_packet_decrypt
2299 to applications. The library calls now a generic
2300 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2301 when the packet is either normal or special. This was done to
2302 allow more wide range of checking that was not allowed when
2303 the code was in library. Now applications can do virtually any
2304 checks to the packet and return to the library the decision how
2305 the packet should be processed. Affected files are
2306 lib/silccore/silcpacket.[ch].
2308 Added silc_server_packet_decrypt_check to the server and
2309 silc_client_packet_decrypt_check to the client library.
2311 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2312 to send with specified source and destination information.
2314 * Channel message delivery between routers was broken after the
2315 channel key distribution was fixed earlier. The channel key
2316 was used be to distributed to other routers as well which is not
2317 allowed by the protocol. Now this is fixed and channel keys
2318 really are cell specific and the channel message delivery between
2319 routers comply with the protocol specification.
2321 * Fixed various commands in server to check also the global list
2322 for the channel entry and not just the local list. The affected
2323 file silcd/command.c.
2325 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2327 * Added assert()s to buffer formatting and unformatting routines
2328 to assert (if --enable-debug) when error occurs. Affected
2329 file: lib/silcutil/silcbuffmt.c.
2331 * Changed to auto-reconnect to check whether the remote host is
2332 router and register the re-connect timeout if it is. It used
2333 to check that whether we are normal server, but router must do
2334 auto-reconnect with another router as well. Affected file
2337 * Removed the [<key len>] option from CMODE command as the cipher
2338 name decides the key length, nowadays. See the defined ciphers
2339 from the protocol specification.
2341 * Added [<hmac>] option to the CMODE command to define the HMAC
2342 for the channel. Added SILC_CMODE_HMAC channel mode.
2344 * Added [<hmac>] option for the JOIN command so that user can
2345 select which HMAC is used to compute the MACs of the channel
2348 * Added Hmac field to the Channel Message Payload. The integrity
2349 of plaintext channel messages are now protected by computing
2350 MAC of the message and attaching the MAC to the payload. The
2351 MAC is encrypted. Now, it is clear that this causes some
2352 overhead to the size of the packet but rationale for this is that
2353 now the receiver can verify whether the channel message decrypted
2354 correctly and also when private keys are set for the channel the
2355 receiver can decrypt the packet with several keys and check from
2356 the MAC which key decrypted the message correctly.
2358 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2359 lib/silccrypt/silccipher.[ch].
2361 * Added silc_hash_len to return the digest length into the
2362 lib/silcrypt/silchash.[ch].
2364 * Rewrote parts of Silc Channel Payload interface in the
2365 lib/silccore/silcchannel.[ch]. The encode function now also
2366 encrypts the packet and parse function decrypts it.
2368 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Fixed a minor formatting bug in the SKE's key material processing.
2371 It actually might have processed the keys wrong way resulting
2374 * Redefined the mandatory HMAC algorithms and added new algorithms.
2375 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2376 and hmac-md5 truncated to 96 bits. The mandatory is now
2377 hmac-sha1-96. Rest are optional (including the one that used
2378 to be mandatory). Rationale for this is that the truncated HMAC
2379 length is sufficient from security point of view and can actually
2380 make the attack against the HMAC harder. Also, the truncated
2381 HMAC causes less overhead to the packets. See the RFC2104 for
2384 * Added new [hmac] configuration section. The SKE used to use
2385 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2386 is of course wrong. The official names that must be proposed in
2387 the SKE are the ones defined in the protocol specification
2388 (hmac-sha1-96 for example). The user can configure any hmac
2389 using any hash function configured in the [hash] section. At
2390 least, the mandatory must be configured.
2392 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2394 * Added HMAC list to the SKE proposal list. It has now both
2395 hash algorithm list and HMAC list. This makes the protocol
2396 incompatible with previous versions. The SKE now seems to work
2397 the way it is supposed to work, for the first time actually.
2399 * Defined plain Hash algorithms to the protocol specification.
2402 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Implemented support for key agreement packets into the server.
2405 Added functions silc_server_key_agreement and
2406 silc_server_send_key_agreement. Other than these functions,
2407 server has nothing to do with this packet.
2409 * Added support for private message key packets into the server.
2410 Added functions silc_server_private_message_key and
2411 silc_server_send_private_message_key.
2415 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2416 called in the protocol's final callback instead in the END
2417 protocol state. This makes a little more sense and in the same
2418 time in client we can use the same protocol routines for normal
2419 key exchange and to key agreement packet handling as well.
2421 * Added to both client's and server's KE protocol context the
2422 SilcSKEKeyMaterial pointer to save the key material. We will
2423 bring the key material to the protocol's final callback by doing
2424 this. The final callback must free the key material.
2426 * Added SKE's packet_send callback into client's KE protocol
2427 context so that the caller can choose what packet sending function
2428 is used. This way we can use different packet sending when
2429 doing normal SKE when doing key agreement packet handling (in
2430 the key agreement packet handling we do not want to encrypt
2433 * Implemented the responder side of the key agreement routines
2434 in the client. The client can now bind to specified port and
2435 accept incoming key negotiation. The key material is passed
2436 to the application after the protocol is over.
2438 * Implemented the processing of incoming Key Agreement packet
2439 in the client. Added function silc_client_key_agreement to
2442 * Implemented the intiator side of the key agreement routines
2443 in the client. The client can now initiate key agreement with
2444 another remote client. The key material is passed to the
2445 application after the protocol is over.
2447 * Created client_keyagr.c to include all the key agreement
2450 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2451 SILC_TASK_CALLBACK except that it is not static.
2453 * Created client_notify.c and moved the Notify packet handling
2454 from the client.[ch] into that file.
2456 * Created client_prvmsg.c and moved all private message and
2457 private message key routines from the client.[ch] into that file.
2459 * Create client_channel.c and moved all channel message and
2460 channel private key routines from the client.[ch] into that file.
2462 * Changed silc_client_get_client_by_id_resolve to resolve with
2463 WHOIS command instead of IDENTIFY command, in the file
2464 lib/silclient/idlist.c.
2466 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Implemented the SKE's responder side to the Client library.
2470 * When FAILURE is received to the protocol do not trust it
2471 blindly. Register a timeout to wait whether the remote closes
2472 the connection as it should do it, only after that process the
2473 actual failure. This was changed to both client and server.
2475 * Added client_internal.h to include some of the structures
2476 there instead of client.h in lib/silcclient/.
2478 * Added function silc_task_unregister_by_callback to unregister
2479 timeouts by the callback function.
2481 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2483 * Some "Incomplete WHOIS info" errors has been appearing on the
2484 log files. Took away the entry->userinfo check from WHOIS
2485 reply sending. The entry->userinfo is now " " if client did not
2486 provide one. I thought this was fixed earlier but something
2487 is wrong still. Let's see if the error still appears.
2489 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Fixed a minor bug in the login when the channel key is
2492 re-generated in the server. It used to generate the key in
2493 wrong order and thus caused problems in the channel traffic.
2495 * Fixed a minor bug in channel key distsribution after
2496 KICK command. The key was not sent to the router even though
2499 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * Added silc_ske_process_key_material_data as generic routine
2502 to process any key material as the SILC protocol dictates. The
2503 function is used by the actual SKE library but can be used by
2504 applications as well. This relates to the private message keys
2505 and the channel private keys since they must be processed the
2506 same way the normal SILC session keys. The protocol dictates
2507 this. Affected files: lib/silcske/silcske.[ch].
2509 Added also silc_ske_free_key_material to free the
2510 SilcSKEKeyMaterial structure.
2512 * Defined silc_cipher_set_key function to set the key for
2513 cipher without using the object's method function. The affected
2514 files: lib/silccrypt/silccipher.[ch].
2516 * Implemented silc silc_client_add_private_message_key,
2517 silc_client_add_private_message_key_ske,
2518 silc_client_del_private_message_key,
2519 silc_client_list_private_message_keys and
2520 silc_client_free_private_message_keys functions in the
2523 Added functions silc_client_send_private_message_key to send
2524 the Private Message Key payload and silc_client_private_message_key
2525 to handle incoming Private Message Key payload.
2527 * Added Cipher field to the Private Message Key payload to set
2528 the cipher to be used. If ignored, the default cipher defined
2529 in the SILC protocol (aes-256-cbc) is used.
2531 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2533 * Removed lib/silcclient/ops.h file.
2535 Redefined parts of the SILC Client Library API. Created new
2536 file silcapi.h that deprecates the ops.h file and defines the
2537 published Client Library API. Defined also private message key
2538 API and channel private key API into the file.
2540 This is the file that the application must include from the
2541 SILC Client Library. Other files need not be included by
2542 the application anymore.
2544 * Added new key_agreement client operation callback and also
2545 defined the Key Agreement library API for the application.
2547 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2549 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2550 is used by clients to request key negotiation between another
2551 client in the SILC network. If the negotiation is started it
2552 is performed using the SKE protocol. The result of the
2553 negotiation, the secret key material, can be used for example
2554 as private message key.
2556 Implemented the Key Agreement payload into the files
2557 lib/silccore/silauth.[ch].
2559 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2561 * Redefined ciphers for the SILC protocol. Added some new ciphers
2562 and defined the key lengths for the algorithms. Changed the
2563 code accordingly. The default key length is now 256 bits.
2565 * Fixed SKE key distribution function silc_ske_process_key_material
2566 when the key length is more than 128 bits. The default key
2567 length in SILC is now 256 bits.
2569 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2570 to indicate unsupported algorithm.
2572 * Renamed rijndael.c to aes.c and all functions as well.
2574 * Fixed a long standing channel key setting bug in client library.
2575 Weird that it has never surfaced before.
2577 * Fixed bug in channel deletion. If the entire channel is removed
2578 then it must also delete the references of the channel entry
2579 from the client's channel list as the client's channel entry and
2580 the channel's client entry share same memory.
2582 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2584 * Implemented CONNECT and SHUTDOWN commands in the client.
2586 * Implemented CLOSE command to the client.
2588 * Added the function silc_idlist_find_server_by_name into the
2589 files silcd/idlist.[ch].
2591 Added the function silc_idlist_find_server_by_conn into the
2592 files silcd/idlist.[ch].
2594 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * DIE command was renamed to SHUTDOWN. Updated the both code
2599 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2600 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2602 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2605 * Added function silc_server_create_connection function to create
2606 connection to remote router. My server implementation actually
2607 does not allow router to connect to normal server (it expects
2608 that normal server always initiates the connection to the router)
2609 so the CONNECT command is only good for connecting to another
2612 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2614 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2615 or some other client was kicked from the channel.
2617 Implemented the handling of the notify type to both client
2620 Implemented silc_server_send_notify_kicked to send the KICKED
2621 notify. It is used to send it to the server's primary router.
2623 * Implemented the KICK command into server and client.
2625 * Added `query' argument to the silc_idlist_get_client function
2626 to indicate whether to query the client from server or not if
2629 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2630 to indicate that the client is not channel founder.
2634 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2636 * Removed the rng context from SilcPacketContext structure and
2637 changed that the packet routine uses the Global RNG API.
2639 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2641 * Added support for quit message that client can "leave" on the
2642 channel when it quits the SILC. It is ditributed inside the
2643 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2645 Added silc_server_free_client_data that will take the
2646 signoff message as argument.
2648 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2650 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Updated parts of the protocol specification to keep it up
2655 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2658 payloads in one packet.
2660 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2661 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2662 use now the new List flag.
2664 * Also deprecated the following packet types: REPLACE_ID,
2665 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2667 * Added list support for Notify packet in server.
2669 * Added silc_server_send_notify_channel_change to send the
2670 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2671 the silc_server_send_replace_id.
2673 * Added silc_server_send_notify_nick_change to send the
2674 NICK_CHANGE notify type. Deprecates the function
2675 silc_server_send_replace_id.
2677 * Added silc_server_send_notify_join to send the JOIN notify type.
2678 Deprecates the function silc_server_send_new_channel_user.
2680 * Added silc_server_send_notify_leave to send LEAVE notify type.
2681 Deprecates the function silc_server_send_remove_channel_user.
2683 * Added silc_server_send_notify_cmode and
2684 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2685 types. Deprecates the silc_server_send_set_mode function.
2687 * Added SERVER_SIGNOFF notify type to indicate that server has
2688 quit. This means that all clients on the channel from that
2689 server will drop. This can be also used when netsplit happens.
2691 Deprecated REMOVE_ID packet type since it is not needed anymore
2694 Added silc_server_send_notify_server_signoff to send the
2695 SERVER_SIGNOFF notify type. Deprecates the function
2696 silc_server_send_remove_id.
2698 Added also silc_server_send_notify_signoff to send the
2699 SIGNOFF notify type.
2701 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2702 SILC protocol from this day on. Changed the protocol
2703 specification as well.
2705 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2706 notify type. It is used between routers to notify about
2707 topic changes on a channel.
2709 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2712 * Partly updated the protocol specification to comply with the
2713 changes now made. It is still though a bit outdated.
2715 * The JOIN notify type now takes one extra argument <Channel ID>.
2716 The packet used to be destined to the channel but now the
2717 JOIN type may be sent as list thus it is impossible to
2718 destine it to any specific channel. By adding this argument
2719 it is again possible.
2721 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Added CREDITS file. The CHANGES and CREDITS file will appear
2724 in the distribution as well.
2726 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2729 types in the server's silcd/packet_receive.c.
2731 * Implemented CMODE and CUMODE to work in router environment.
2733 * Fixed minor encoding and decoding buglet from the
2734 lib/silccore/silcmode.c.
2736 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2739 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2741 * Changed all SilcConfigServer* and silc_config_server* to
2742 SilcServerConfig* and silc_server_config*, respectively.
2745 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * Associated the ID (client or server ID) to the Authentication
2748 Payload to avoid any possibility of forging. Updated the
2749 protocol specification and the code accordingly.
2751 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * The RSA key length is now save to the RsaKey context in the
2754 key generation process in lib/silccrypt/rsa.c. The key length
2755 is now used to figure out the maximum size of the block allowed
2756 to be encrypted/signed.
2758 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2759 is equivalent to the silc_mp_mp2bin but does not allocate any
2762 * Changed silc_mp_mp2bin API to take length argument. If it is
2763 non-zero then the buffer is allocated that large. If zero, then
2764 the size is approximated using silc_mp_sizeinbase, which however
2767 * Created Global RNG API which is global RNG that application can
2768 initialize. After initializing, any routine anywhere in the
2769 code (including library) can use RNG without allocating a new
2770 RNG object. This was done to allow this sort of use of the
2771 RNG in code that has no chance to allocate RNG object. All
2772 applications currently allocate this and many routines in the
2773 library use this. Affected file lib/silccrypt/silcrng.[ch].
2775 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2776 it to use the Global RNG API.
2778 * Defined Authentication Payload into protocol specification that
2779 is used during SILC session to authenticate entities. It is
2780 used for example by client to authenticate itself to the server
2781 to obtain server operator privileges.
2783 Implemented this payload into the lib/silccore/silcauth.[ch].
2784 Implemented also routines for public key based authentication
2785 as the new protocol specification dictates.
2787 Moved definitions of different authentication methods from
2788 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2790 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2791 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2792 silc_pkcs_verify_with_hash functions into the file
2793 lib/silccrypt/silcpkcs.[ch].
2795 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * The client entry's userinfo pointer must be always valid.
2798 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2799 will fail since it requires the userinfo. Now, the userinfo
2800 is allocated as "" if actual userinfo does not exist. Actually,
2801 it must exist and it is totally Ok to drop client connections
2802 that does not announce the userinfo. However, we will make
2803 this workaround for now.
2805 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2806 to return the remote port by socket.
2808 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2810 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2811 SILC_SERVER_PENDING_EXEC and added an new macro
2812 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2813 data or when error occurs while processing the pending command.
2815 Added new argument `destructor' into silc_server_command_pending
2816 and to the SilcServerCommandPending object. This destructor is
2817 now called after calling the pending callback or if error occurs
2818 immediately. If error occurs the actual pending callback won't
2819 be called at all - only the destructor. The destructor may be
2820 NULL if destructor is not needed.
2822 All this applies for client library code as well. Similar
2823 changes were made there as well for the pending commands.
2825 In the client, the application must now allocate the
2826 SilcClientCommandContext with the silc_client_command_alloc
2829 * Added reference counter to the SilcServerCommandContext. Added
2830 function silc_server_command_alloc and silc_server_command_dup
2833 Same type of functions added to the client library for the same
2836 * Removed the cmd_ident from IDListData away since it is now
2837 global for all connections. It is the command identifier used
2838 in command sending and with pending commands. The affected file
2841 * Added reference counter to the SilcSocketConnection objecet to
2842 indicate the usage count of the object. The object won't be
2843 freed untill the reference counter hits zero. Currently only
2844 server uses this, and client ignores it. The client must be
2845 set to use this too later. The affected files are
2846 lib/silccore/silcsockconn.[ch]. Added also the function
2847 silc_socket_dup to increase the reference counter.
2849 This was mainly added because it is possible that the socket
2850 is removed underneath of pending command or other async
2851 operation. Now it won't be free'd and proper DISCONNECTING
2852 flags, etc. can be set to avoid sending data to connection that
2853 is not valid anymore.
2855 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2856 the connection. After that it sets SILC_SET_DISCONNECTED.
2857 It is, however, possible that the socket data is not still freed.
2858 The silc_server_packet_process now checks that data is not
2859 read or written to connection that is DISCONNECTED. The socket
2860 get's freed when the reference counter hits zero.
2862 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Changed the client operation API: channel_message operation's
2865 `sender' is now the client entry of the sender, not the nickname
2866 and the `channel' is the channel entry, not the channel name.
2868 In the private_message operation the `sender' is now also the
2869 client entry of the sender not the nickname.
2871 Affected file is lib/silcclient/ops.h and all applications
2872 using the client operations.
2874 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Moved the calling of ops->connect() from connect_to_server_final
2877 into receive_new_id functin since that is the point when the
2878 client is actually allowed to send traffic to network. The
2879 affected file is lib/silcclient/client.c.
2881 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2883 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2884 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2885 (if needs broadcasting) instead of broadcasting the packets one
2886 by one which would make a burst in the network traffic.
2888 * Added `broadcast' argument to the functions in silcd/server.[ch]
2889 silc_server_create_new_channel[_with_id] to indicate whether
2890 to send New Channel packet to primary router.
2892 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Added new function into the silcd/server.[ch] files:
2895 silc_server_create_new_channel_with_id to create new channel with
2896 already existing Channel ID.
2898 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2899 lib/silccore/silcpacket.h. This packet is used t send list of
2900 Set Mode payloads inside one packet. Server uses this to set
2901 the modes for the channels and clients on those channels, that it
2902 announced to the router when it connected to it. The protocol
2903 specification has been updated accordingly.
2905 * The silc_server_new_channel did not handle the packet coming
2906 from normal server as it normally does not send that. However,
2907 when it announces its channels it does send it. Implemented
2908 the support for that.
2910 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2911 into the file lib/silccore/id.h.
2913 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2915 * Fixed memory leaks in the functions silc_idlist_del_client,
2916 silc_idlist_del_channel and silc_idlist_del_server in the file
2917 silcd/idlist.c. All of those leaked like a sieve.
2919 * Fixed some small memory leaks in the client's function
2920 silc_client_notify_by_server.
2922 * Added functions into silcd/server.c: silc_server_announce_clients,
2923 silc_server_announce_channels and silc_server_announce_server.
2924 These functions are used by normal and router server to announce
2925 to its primary router about clients, channels and servers (when
2926 router) that we own. This is done after we've connected to the
2929 These functions effectively implements the following packet types:
2930 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2931 and SILC_PACKET_NEW_ID_LIST.
2933 * Added new functions into the silcd/packet_receive.[ch]:
2934 silc_server_new_id_list, silc_server_new_channel_list and
2935 silc_server_new_channel_user_list to handle the incoming
2936 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2938 * Added support of changing Channel ID in the function
2939 silc_server_replace_id. If the server that announces a channel
2940 to the router already exists in the router (with same name but
2941 with different Channel ID), router is responsible to send
2942 Replace ID packet to the server and force the server to change
2943 the Channel ID to the one router has.
2945 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2946 client that the Channel ID has been changed by the router. The
2947 normal server sends this to the client. Client must start using
2948 the new Channel ID as the channel's ID.
2950 Implemented handling of this new type into lib/silcclient/client.c
2951 into the function silc_client_notify_by_server.
2953 * Added new function silc_idlist_replace_channel_id into the files
2954 silcd/idlist.[ch] to replace the Channel ID.
2956 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2958 * Call silc_server_command_identify_check always when processing
2959 the IDENTIFY command in silcd/command.c
2961 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2964 send keepalive packets. The packet can be sent by clients,
2965 servers and routers.
2967 Added function silc_socket_set_heartbeat into the file
2968 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2969 If not set, the heartbeat is not performed. The actual
2970 heartbeat is implemented in the low level socket connection
2971 library. However, application is responsible of actually
2974 Added silc_server_send_heartbeat to send the actual heartbeat
2975 packet into silcd/packet_send.[ch]. Server now performs
2976 keepalive with all connections.
2978 * Added silc_task_get_first function into lib/silcutil/silctask.c
2979 to return the timeout task with shortest timeout. There was a bug
2980 in task unregistration that caused problems. TODO has been
2981 updated to include that task system must be rewritten.
2983 * The client library will now resolve the client information when
2984 receiving JOIN notify from server for client that we know but
2985 have incomplete information.
2987 * Rewrote parts of silc_server_remove_from_channels and
2988 silc_server_remove_from_one_channel as they did not remove the
2989 channel in some circumstances even though they should've.
2991 * Encryption problem encountered in server:
2993 The LEAVE command used to send the Channel Key packet to the
2994 router immediately after generating it. However, the code
2995 had earlier sent Remove Channel user packet but not immediately,
2996 ie. it was put to queue. The order of packets in the router
2997 was that Channel Key packet was first and Remove Channel User
2998 packet was second, even though they were encrypted in the
2999 reverse order. For this reason, MAC check failed. Now, this
3000 is fixed by not sending the Channel Key packet immediately but
3001 putting it to queue. However, this is more fundamental problem:
3002 packets that are in queue should actually not be encrypted
3003 because packets that are sent immediately gets encrypted
3004 actually with wrong IV (and thus MAC check fails). So, packets
3005 that are in queue should be encrypted when they are sent to
3006 the wire and not when they put to the queue.
3008 However, the problem is that the current system has not been
3009 designed to work that way. Instead, the packet is encrypted
3010 as soon as possible and left to the queue. The queue is then
3011 just purged into wire. There won't be any fixes for this
3012 any time soon. So, the current semantic for packet sending
3015 o If you send packet to remote host and do not force the send
3016 (the packet will be in queue) then all subsequent packets to the
3017 same remote host must also be put to the queue. Only after the
3018 queue has been purged is it safe again to force the packet
3021 o If you send all packets immediately then it safe to send
3022 any of subsequent packets through the queue, however, after
3023 the first packet is put to queue then any subsequent packets
3024 must also be put to the queue.
3026 Follow these rules and everything works fine.
3028 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Added new function silc_server_remove_clients_by_server to
3031 remove all client entries from ID list when the server connection
3032 is lost. In this case it is also important to invalidate all
3033 client entires as they hold the invalid server entry. This
3034 fixes fatal bug when server has lost connection and will reconnect
3037 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3039 * Made some sanity checks to silc_server_daemonise like to check
3040 whether the requested user and group actually exists.
3042 * Added sanity check to SKE's silc_ske_responder_finish to check
3043 that the public and private key actually is valid.
3045 * Invalidate the client's nickname when receiving Replace ID
3046 packet and the Client ID is being replaced. This means that the
3047 server will query the nickname if someone needs it (client)
3050 * Sort the ID Cache in client library when the ID Cache data
3051 has changed (needs sorting).
3053 * Do not allow for SILC client to create several connections to
3054 several servers. The client does not support windows right now
3055 and generating multiple connections causes weird behaviour.
3057 Irssi-silc client does support windows and can handle several
3058 connections without problems, see: www.irssi.org and SILC plugin.
3060 * Fixed some places where client was added to the IDList. The
3061 rule of thumb is following (in order to get everything right):
3062 If the client is directly connected local client then the
3063 `connection' argument must be set and `router' argument must be
3064 NULL to silc_idlist_add_client function. If the client is not
3065 directly connected client then the `router' argument must
3066 bet set and the `connection' argument must be NULL to the
3067 silc_idlist_add_client function.
3069 * The funtion silc_server_packet_send_local_channel actually did
3070 not check whether the client was locally connected or not. It
3071 does that now. Fixed a bug related to LEAVE command.
3073 * Fixed Remove Channel User payload parsing bug in server's
3074 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3076 * The server's silc_server_save_channel_key now checks also the
3077 global ID list for the channel as it might not be in the local
3078 list. Fixed a bug related to LEAVE command.
3080 * Is this the end of the [<unknown>] buglet that has been lurking
3081 around for a long time? A little for loop fix in server's
3082 silc_server_command_whois_parse that is used by both IDENTIFY
3083 and WHOIS command. At least, this was a clear bug and a cause
3084 of one type of [<unknown>] buglet.
3086 * WHOIS and IDENTIFY commands call the function
3087 silc_server_command_[whois/identify]_check function even if
3088 we are not router server.
3090 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Added --with-gmp configuration option. If set the GMP
3093 is always compiled in the SILC source tree. If not set then
3094 it is checked whether the system has the GMP3 installed. If
3095 it has then the GMP won't be compiled (the system's headers
3096 and library is used), if it doesn't have it then the GMP is
3097 compiled in the SILC source tree.
3099 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3101 * Changed RSA private exponent generation to what PKCS #1
3102 suggests. We try to find the smallest possible d by doing
3103 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3104 not security fix but optimization.
3106 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Added new config entry [Identity] to fork the server and run
3109 it as specific user and group. A patch from Bostik.
3111 * Imported Dotconf configuration library into lib/dotconf.
3112 This will be used to create the SILC configuration files later.
3113 It will appear in the distsribution after this commit.
3115 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * A big code auditing weekend happening. Auditing code for
3118 obvious mistakes, bugs and errors. Also, removing any code
3121 Removed files for being obsolete:
3123 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3124 inline in the file lib/silcutil/silcbuffer.h)
3126 o lib/silcutil/silcbufutil.c (the header has inline versions)
3128 Changed code to fix possible error conditions:
3130 o The buffer formatting routines now check that the destination
3131 buffer really has enough space to add the data. This applies for
3132 both buffer formatting and unformatting
3133 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3134 unformatting was changed to accomodate following rules:
3135 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3136 sent to the function while XXX_*STRING will not allocate or copy
3137 the data into the buffer. Instead it sets the pointer from the
3138 buffer into the pointer sent as argument (XXX_*STRING used to
3139 require that the pointer must be allocated already). This change
3140 makes this whole thing a bit more consistent and more optimized
3141 (note that the data returned in the unformatting with XXX_*STRING
3142 must not be freed now). The routines return now -1 on error.
3144 o Tried to find all code that use buffer_format and buffer_unformat
3145 and added return value checking to prevent formatting and
3146 especially unformatting errors and possible subsequent fatal
3149 o Changed ske->x and ske->KEY to mallocated pointers in
3150 lib/silcske/silcske.h. Fixed possible data and memory leak.
3152 o Added return value checking to all *_parse* functions. Fixed
3153 many memory leaks as well.
3155 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3156 so that buffer overflows would not happen. All code now also
3157 checks the return value as it can fail.
3159 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Added reconnection support to server if the normal server looses
3162 its connection to the router (for example if router is rebooted).
3163 The server performs normal reconnection strategy implemented
3164 to the server. Affected file silcd/server.c.
3166 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Added new packet type SILC_PACKET_SET_MODE that is used to
3169 distribute the information about changed modes (for clients,
3170 channels and clients channel modes) to all routers in the
3171 network. Updated the protocol specification accordingly.
3173 Added functions into silcd/packet_send.c and
3174 silcd/packet_receive.c: silc_server_send_set_mode,
3175 silc_server_set_mode.
3177 Added new files silcmode.[ch] into lib/silccore that implements
3178 the encoding and decoding of Set Mode Payload. Added new type
3179 SilcSetModePayload. Moved the definitions of different modes
3180 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3182 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3184 * Oops, a little mistake in server's connection authentication
3185 protocol. The protocol is not ended with FAILURE but with
3186 SUCCESS if the authentication is Ok. :) Affected file is
3189 * Implemented NICK_CHANGE notify handling in server in the file
3190 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3191 the local clients on the channel. After the changing nickname
3192 in router environment snhould work and the [<unknown>] nickname
3193 should appear no more.
3195 The silc_server_replace_id function that receives the Replace ID
3196 payload now sends the NICK_CHANGE notify type also in the file
3197 silcd/packet_receive.c
3199 * Changed WHOIS and IDENTIFY command to support the maximum amount
3200 of arguments defined in protocol specs (3328 arguments). This
3201 fixed a bug that caused problems when there were more than three
3204 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Added extra parameter, command identifier, to the
3207 silc_client_send_command so that explicit command identifier
3210 Changed that ID list routines uses specific command identifier
3211 when sending WHOIS/IDENTIFY requests to the server so that they
3212 can be identified when the reply comes back.
3214 Affected files lib/silcclient/command.[ch],
3215 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3217 * Added `sender' argument to silc_server_packet_send_to_channel
3218 to indicaet the sender who originally sent the packet to us
3219 that we are now re-sending. Ignored if NULL. Affected file
3220 silcd/packet_send.[ch].
3222 * Added some server statistics support in silcd/server_internal.h
3223 SilcServerStatistics structure and around the server code. Also
3224 send some nice statistics information when client is connecting
3227 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Fixed channel ID decoding in server's JOIN command reply in
3230 silcd/command_reply.c
3232 * Fixed braodcasting of replace ID payload to not to send it if
3233 we are standalone server in silcd/packet_receive.c.
3235 * Fixed all channel message sending routines to not to send
3236 packets to clients that has router set, since they are routed
3237 separately in the same function earlier. Affects file
3238 silcd/packet_send.c and all channel packet sending functions.
3240 * In USERS reply, res_argv[i] are not allocated, the table
3241 is allocated. Thus changed that free the table, not its
3244 * In server's whois_check and identify_check if the client is
3245 locally connected do not send any WHOIS commands - they are not
3248 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3250 * Fixed some minor bugs in client when sending WHOIS command. The
3251 arguments was in wrong order.
3253 * Removed statis function add_to_channel from server in
3254 silcd/command.c that was previously used with the joining but
3257 * Tested USERS command in router environment successfully with two
3258 routers, two servers and two clients.
3260 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Reorganized the USERS command and command reply in client library
3263 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3264 When the command is given by user we register a pending command
3265 callback that will reprocess the command after the reply has been
3266 received from the server. When reprocessing the packet we then
3267 display the information. Thus, the USERS information is displayed
3268 now in the command callback instead of in the command reply
3269 callback. The processing of the command is same as previously
3270 when server has sent the command reply in the JOINing process.
3272 * Added to USERS command in silcd/command_reply.c to join the client,
3273 we didn't use to know about, to the channel after we've created
3274 a client entry for it. Also, for clienet we did know already still
3275 check whether it is on the channel or not and add it if not.
3277 * Removed silc_server_command_join_notify as the function and its
3280 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Changed the client's pending command handling to the same as the
3283 server's pending command handling. It is also now possible to
3284 execute command reply functions from other command reply
3285 function as the function callbacks for commands and command
3286 replies are one and same. The pending commands are not static
3287 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3288 in client connection context. Thus, pending commands are server
3289 connection specific as it is convenient.
3291 Changed the function silc_client_command_pending and
3292 silc_client_command_pending_del and added new function
3293 silc_client_command_pending_check. Removed the
3294 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3297 * Added cmd_ident, current command identifier, to the client
3298 connection context in lib/silcclient/client.h to keep track on
3299 command identifiers used in command sending. Client's command reply
3300 function handling now supports the mandatory command identifiers.
3302 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3303 funtions in client to fully support pending command callbacks.
3305 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3306 as one of the arguments to the application in the command reply
3309 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3310 before first releasing SILC but came back. Now it is removed again
3311 and should come back nomore. The FORWARDED flag was used only
3312 by the JOINing procedure by forwarding the command packet to router.
3313 Now, the JOINing procedure has been changed to more generic (due
3314 to various router environment issues) and FORWARDED is not needed
3315 anymore for anything. The protocol specification is yet to be
3318 Now, removed silc_server_packet_forward from server and the flag
3319 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3321 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * Renamed NAMES command to USERS command. The NAMES was named that
3324 due to historical reasons. Now it is renamed. Also, rewrote
3325 parts of the USERS command. The nickname list is not sent anymore
3326 by the server. Only Client ID and mode lists are sent in the USERS
3327 command. Changed this also to the protocol specification.
3329 The client now resolves the names and stuff after it receives
3330 the USERS list from the server when joining to the channel.
3332 * WHOIS and IDENTIFY commands has been changed to support multiple
3333 Client ID's per command. One can now search for multiple users
3334 in the network by sending only one WHOIS or IDENTIFY command.
3335 Changed the code and the protocol specifications.
3337 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3338 uses silc_server_command_whois_parse to parse the request. */
3340 * If normal server, do not parse the WHOIS and IDENTIFY requests
3341 before sending it to the router. Saves some time.
3343 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Fixed JOIN command on client library. Wrong number of arguments
3346 used to crash the client.
3348 * Added silc_server_channel_has_global function to check whether
3349 channel has global users or not.
3351 * Added silc_server_channel_has_local function to check whether channel
3352 has locally connected clients on the channel.
3354 * The silc_server_remove_from_one_channel now checks whether the
3355 channel has global users or not after given client was removed from
3356 the channel. It also checks whether the channel has local clients
3357 on the channel anymore. If it does not have then the channel entry
3358 is removed as it is not needed anymore.
3360 * The silc_server_notify now checks on JOIN notify whether the joining
3361 client is one of locally connected or global. If it is global then
3362 the channel has now global users on the channel and that is marked
3363 to the channel entry. Also, it now saves the global client to
3364 global list who is joining and JOINs it to the channel. This is
3365 for normal server, that is.
3367 Changed silc_server_send_notify_on_channel,
3368 silc_server_packet_relay_to_channel and
3369 silc_server_packet_send_to_channel check if we are normal server
3370 and client has router set (ie. global client) do not send the
3371 message to that client, as it is already routed to our router.
3373 * Implemented LEAVE notify type handling in silc_server_notify
3376 * Tested LEAVE command in router environment successfully. Tested
3377 with two routers, two servers and two clients.
3381 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3383 * Implemented SIGNOFF notify type handling in silc_server_notify
3386 * silc_server_remove_id now removes the client entry from all channels
3387 it has joined and thusly sends SIGNOFF notify type.
3389 * Rewrote the NAMES list generation in server by removing two excess
3390 loops. The lists are created now inside one loop.
3392 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3394 * silc_server_remove_channel_user checks now also global list
3395 for channel and client.
3397 * silc_server_new_channel_user checks now both local and global
3398 list for channel and client. Fixed a bug in client id decoding.
3399 Used to decode wrong buffer.
3401 * silc_server_channel_message checks now both local and global
3402 list for channel entry.
3404 * Tested channel joining (hence JOIN) in router environment
3405 successfully. Tested with two routers, two servers and two
3408 * Tested channel message sending in router environment successfully.
3410 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * Added silc_server_save_channel_key into server.[ch] to save the
3413 received channel key in Channel Key payload processing. It is
3414 also used in JOIN command reply handling.
3416 Equivalent function silc_client_save_channel_key added into
3417 client.[ch] into client library.
3419 * Changed JOIN command reply to send information whether the channel
3420 was created or not (is existing already) and the channel key
3421 payload. Changed protocol specs accordingly.
3423 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3424 the request was sent by ID and not by nickname. Crashed on
3427 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3430 now correctly save the received data.
3432 * silc_server_free_sock_user_data now notifies routers in the
3433 network about entities leaving the network.
3435 At the same time implemented functions silc_server_remove_id
3436 and silc_server_send_remove_id to receive and send REMOVE_ID
3437 packets. The packet is used to notify routers in the network
3438 about leaving entities. The ID removed will become invalid in
3441 * Added function silc_idlist_del_server into server. Removes and
3442 free's server entry from ID list.
3444 * silc_server_private_message function now checks, if we are router,
3445 that the destination ID really is valid ID, naturally.
3447 * In router when NEW_ID packet is received (for new client) the
3448 hash of the Client ID is saved in the ID Cache but the
3449 client->nickname is set to NULL, instead of putting the hash
3452 IDENTIFY command now also checks that client->nickname must be
3453 valid. If it is not if will request the data from the server who
3454 owns the client. Added new function
3455 silc_server_command_identify_check.
3457 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3458 to set the command to already allocated Command Payload.
3460 * Tested private message sending in router environment with two
3461 routers, two servers and two clients. Fixed minor bugs and now
3464 * Fixed segfault from client's NAMES command. Used to crash if
3467 * Forwarded packets must not be routed even if it is not destined
3468 to the receiver. Changed server code comply with this.
3470 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * Added `require_reverse_mapping' boolean value to ServerParams
3473 structure. If TRUE (not default) the server will require that
3474 the connecting host has fully qualified domain name.
3476 If the reverse mapping is not required and hostname could not be
3477 found the IP address is used as hostname.
3479 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Implemented version string checking to both client and server.
3482 The check is incomplete currently due to the abnormal version
3483 strings used in development version of SILC.
3485 * Changed all command functions in server to use the new
3488 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3490 * Changed char *data to unsigned char *data in ID Cache system to
3491 support binary data as ID Cache data. Changed code to support
3492 binary data in lib/silccore/idcache.c.
3494 * Renamed silc_server_packet_relay_command_reply to
3495 silc_server_command_reply as it is normal packet receiving
3496 function. Rewrote the function to accept command replys for
3497 servers and not only for clients.
3499 * Mark remote router always as registered server if we are connecting
3500 to it. Otherwise, commands sent by the router to us are ignored.
3502 * All ID List find routines now returns the ID Cache Entry pointer
3503 as well if requested.
3505 * WHOIS command works now in router environment, tested with two
3506 routers, two servers and two clients.
3508 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3509 in router environment (as it is almost equivalent to WHOIS) but
3510 hasn't been tested thoroughly. Added new functions:
3512 silc_server_command_identify_parse
3513 silc_server_command_identify_send_reply
3514 silc_server_command_identify_from_client
3515 silc_server_command_identify_from_server
3517 * Disabled route cache adding because adding two different ID's with
3518 same IP replaces the old cache entry thus giving wrong route.
3519 The entry->router->connection is always the fastest route anyway
3520 so route cache may not be needed. Of course, new routes maybe
3521 established after receiving the ID when the entry->router->connection
3522 might not be anymore the most optimal.
3524 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Add route cache for received ID for fast routing.
3528 * Added silc_server_packet_route to route received packet on router
3529 that is not destined to us.
3531 * Renamed silc_server_get_route to silc_server_route_get.
3533 * Added id_string and id_string_len fields into SilcServer to
3534 include encoded ServerID for fast comparing without excess
3535 encoding of the ID's.
3537 * Cleaned up WHOIS command on server side. Added following static
3540 silc_server_command_whois_parse
3541 silc_server_command_whois_check
3542 silc_server_command_whois_send_reply
3543 silc_server_command_whois_from_client
3544 silc_server_command_whois_from_server
3546 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3547 arguments in command replies. All command functions should be
3548 updated to use this macro.
3550 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Minor typo fixes on command reply handling on server.
3554 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Added silc_server_command_add_to_channel internal routine to add
3557 the client to the channel after router has created the channel and
3558 sent command reply to the server.
3560 * Added generic silc_server_send_command to send any command from
3563 * Use static buffer with ID rendering instead of duplicating data.
3565 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3567 * Fixed a channel user mode bug when joining to a channel server gave
3568 everybody channel founder rights, oops.
3570 * We mark ourselves as the router of the incoming server connection
3571 if we are router ourselves. This way we can check in some packet
3572 sending functions whether it is locally connected server. For
3573 incoming router connections we put NULL.
3575 * For router sending packets locally means now always sending the
3576 packet cell wide; to local clients and local servers. For normal
3577 server sending packet locally means sending it to only local
3580 * Fixed the JOIN command to really work in router environment. If the
3581 channel is created it is always created by the router. Router is
3582 also responsible of making the initial joining to the channel,
3583 sending JOIN notify to the sending server and distributing
3584 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3585 does not exist server doesn't do anything else but forward the
3586 command to the router which performs everything.
3588 * Added silc_server_send_channel_key function to send the Channel Key
3591 * Added silc_server_create_channel_key to create new channel key. The
3592 channel key is now re-generated everytime someone joins or leaves
3593 a channel, as protocol dictates. Note: channel->key_len is the
3596 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3599 packet_receive.[ch] to separate packet sending and receiving
3600 routines. The server.[ch] now includes everything else including
3601 actual packet processing (writing and reading data) and other
3604 Renamed silc_server_private_message_send_internal to
3605 silc_server_send_private_message. The routine is still though
3606 used only to relay private messages as server does not send
3607 private messages itself.
3609 Renamed silc_server_new_channel to silc_server_create_new_channel
3610 and added new function sicl_server_new_channel that handles the
3611 incoming New Channel packet. Added also new sending function
3612 silc_server_send_new_channel to send New Channel Payload.
3614 * Added new function silc_server_notify to process incoming notify
3615 packet to the server/router. Server may then relay the notify
3616 to clients if needed.
3618 * Added new function silc_server_new_channel_user to process incoming
3619 New Channel User packet. Router will redistribute the packet and
3620 send JOIN notify to its local clients and locally connected servers
3621 if needed. Normal server will send JOIN notify to its local client
3622 on same channel when received this packet. Added also corresponding
3623 sending function silc_server_send_new_channel_user to sent the
3626 * Added boolean route argument to send_notif_to_channel and
3627 packet_send_to_channel functions to attempt to route the packet
3628 if it is TRUE and send only locally if it is FALSE.
3630 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3632 * silc_server_replace_id now broadcasts the received replace ID
3633 packet if it is not broadcast packet already. The router must
3634 broadcast to inform other routers about changed ID.
3636 * Added backpointer to server's router into SilcServer context in
3637 silcd/server_internal.h.
3639 * Fixed silc_server_packet_broadcast to send correct broadcast
3642 * The channel key is now distributed to the local client as soon
3643 as it is received from the router (in router environment) so that
3644 no other packet may be sent for the channel until client has
3647 * silc_server_remove_channel_user now broadcasts the received
3648 Remove Channel User packet if it is not broadcast packet already.
3649 The router must broadcast to inform other routers about removed
3652 * Added users field into SilcPacketContext that is a reference count
3653 of the context. One can increase the reference count by calling
3654 silc_packet_context_dup which is now changed to just increase the
3655 reference count instead of duplicating the data. The reference
3656 count is decresed by calling silc_packet_context_free that will
3657 free the data after the reference count hits zero.
3659 For now on the packet context and everything allocated into it
3660 (including the raw packet from network) must be freed by calling
3661 the new silc_packet_context_free function. Added also new function
3662 silc_packet_context_alloc that must be used now to allocate the
3663 context. This also means that if a routine is asynchronous from
3664 silc_[client/server]_packet_parse_type the packet context must
3665 be duplicated by calling silc_packet_context_dup. Otherwise it
3666 gets free'd after silc_[client/server]_packet_parse_type returns.
3667 Also, one must remember that if packet is duplicated then its
3668 reference count must be decresed by calling the free function as
3669 many times as it was duplicated.
3671 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3672 from both client and server.
3674 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Made joining to a channel working in router environment.
3678 * Cleaned up JOIN command on server side and create function
3679 silc_server_command_join_channel internal routine to make the
3682 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Changed silc_command_pending list to SilcDList. Also, added
3685 `ident' field to SilcServerCommandPending structure to identify
3686 the reply and to call correct callback.
3688 Added silc_server_command_pending_check function to replace the
3689 corresnponding macro. The silc_command_pending list is not
3692 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3693 to set identifier to previously allocated Command Payload. It
3694 is used to set identifier for command when resending Command
3697 * Added silc_command_payload_encode_payload to encode Command
3698 Payload buffer from SilcCommandPayload structure.
3700 * Added silc_argument_payload_encode_payload to encode Argument
3701 payload buffer from SilcArgumentPayload structure.
3703 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Changed WHOIS command to support router connection on server side.
3706 The whois request is always sent to router unless the server is
3707 standalone server. After server has received the reply from the
3708 router will it send the reply to the client.
3710 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3711 broadcast received broadcast packet. The function is used only
3712 by router. The broadcast packet is always sent to the router's
3715 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3716 render given ID to printable string, for log files for example.
3718 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Made basic router to router connections working. At least they
3721 can now connect to each other but nothing really works the way
3722 they are supposed - yet.
3724 * Added new initiator token to RouterConnection configuration
3725 file in silcd/serverconfig.[ch]. It is used to tell whether we
3726 are the initiator to the remote router or whether we'll expect
3727 the other end to connect.
3729 * Moved registering of listener task to silc_server_init, hence
3730 the server starts listenning as soon as it is run, even if it
3731 does not have connections to other routers. Let's see how well
3734 * Changed default connection retry timeouts for more suitable in
3737 * Removed cipher and such arguments from silc_idlist_add_client
3738 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3739 Added new function silc_idlist_add_data to add the keys and stuff
3742 * Added SilcIDListData structure and added it to SilcClientEntry
3743 and SilcServerEntry as their first field in the structure. This
3744 way we can explicitly cast the ID entries to the SilcIDListData
3745 structure and get common data for the entries. In past, we had
3746 to first check what type of connection it is and then cast it to
3747 correct ID entry type. Now, we can directly cast the opaque
3748 pointer to the SilcIDListData (no matter what ID entry it actually
3749 is) and get the data needed.
3751 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3754 in some circumstances even if threre were timeout tasks, though not
3755 IO tasks, but tasks anyway. Now fixed.
3757 * Defined SilcServerConnection structure to hold connection specific
3758 stuff about directly connected servers and routers. The definition
3759 is currently in silcd/server_internal.h. I thought about having
3760 a bit more important role fro this struct but for now it is used
3761 only when connecting to other server (or router actually).
3763 * Added connecting retry support in server when connecting to
3764 router(s). The retry feature implement exponential backoff
3765 algorithm. Also, added SilcServerParams structure to hold default
3766 parameters for server. For now, it include these retry settings
3767 and are hard coded. After server is moded to be as Silc Server
3768 Library this structure will be more important.
3770 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3772 * Changed client librarys channel->clients table to SilcList and
3773 changed code accordingly.
3775 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Changed client's channel table to SilcList and changed code
3778 accordingly. Also changed SilcChannelClientEntry to include back-
3779 pointer to the channel so that client entry can use that structure
3780 as list as well and we have fast cross-reference to the channel.
3781 This change dramatically decreased the complexity of channel
3782 handling with client entry and vice versa (removed one extra
3783 loop when searching for channel entry from many functions).
3785 * Changed server->sim from table to SilcDList and changed code
3788 * NAMES command can now be used from user interface. It will show
3789 the user list on the channel, neatly.
3791 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3792 Code now saves realname of the user if it becomes available.
3794 * Renamed configure.in to configure.in.pre and made ./prepare
3795 script to automatically add correct version string to
3796 configure.in which it creates from configure.in.pre.
3798 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * NAMES command reply now shows users mode with the nickname when
3803 * Moved silc_client_ch[u]mode[_char] functions from
3804 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3805 place sucks, they are utility functions and should be in some
3808 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3810 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3813 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Added TRQ (efficient deque and list library) into lib/trq. This is
3818 a very good list library that is currently used in the SILC. Defined
3819 SilcList API over the library because I didn't like the API very
3820 much. See lib/trq/silclist.h for the API and examples of how to
3821 use the API. Fixed various places in the code to use the new
3822 SilcList API. The SilcList is meant for lists that has a structure
3823 already defined as a list. It is not suitable to add just some
3824 context to the list (in TRQ, the context is the list actually).
3826 So, I defined SilcDList that can be used for the purpose where
3827 predefined list structure does not exit. This can be used as
3828 such list. Now some context just can be added to the SilcDList.
3829 Currently this list is not used in the SILC just yet, though there
3830 are a lot places where this can replace dynamically allocated
3831 tables and I will fix these places, later, to use SilcDList.
3832 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3833 and use TRQ internally).
3835 Also fixed some annoying warning messages that the original TRQ
3836 code generated. Also minor changes to TRQ's Makefile.in.
3838 * Added support for querying by Client ID to both WHOIS and
3839 IDENTIFY commands into server, as required by the protocol.
3841 * Removed method function pointers from SilcBuffer structure. They
3842 weren't used to anything and just increased the context size for
3843 no good reason. This change also made silc_buffer_alloc and
3844 silc_buffer_free functions inline functions.
3846 * Disabled command flooding detection support until it's fixed so
3847 that it accepts commands in but does not execute them more than once
3850 * Added silc_net_localhost(), to return local hostname, into
3851 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3852 that must be initialized before calling silc_client_init.
3854 * Added new function: silc_server_send_notify_on_channels to send
3855 notify messages to all channels client has joined. It is assured
3856 that the message is sent only once per client.
3858 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3859 lib/silcutil/silcutil.[ch] as silc_format function. The new
3860 function is generic and is used by server as well, not only by
3861 the logging routines.
3863 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3864 the provided version string was not acceptable. Added new function:
3865 silc_ske_check_version into lib/silcske/silcske.h. The function
3866 must be implemented by the application (client or server) and it
3867 does not reside in the SKE library. The function checks the version
3868 string remote end sent.
3870 * Added back pointers (to opaque context and to SilcSocketConnection)
3871 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3873 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3874 duplicate packet context structure.
3876 * Changed `notify' client operation to send same arguments as client
3877 receives from server except for ID's. ID's are mapped to correct
3878 ID entry and that is returned. Also, if channel entry is not sent
3879 by server but the notify is for channel the channel entry is sent
3880 to application (otherwise application doesn't know that it is for
3881 channel (library gets it from packet's Destination ID)).
3883 * Added silc_client_remove_from_channels into client library to
3884 remove a client from all channels it has joined to. Used when
3885 received SIGNOFF notify from server. Added also new function
3886 silc_client_replace_from_channels to replace old ID entry with
3887 new ID entry on all channels. Used when received NICK_CHANGE
3890 * Fixed ID Cache list handling in silc_idlist_get_client in
3891 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3892 to get (or query) client by ID.
3894 * Updated TODO list.
3896 * Added connection authentication status message defined by the
3897 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3898 support for these into the code in client and server side.
3900 * Added generic function silc_client_send_command to send any command
3901 with variable argument list. Application should use this function
3902 to send commands if the command functions provided by the library
3903 does not suite for the application's user interface needs.
3905 * Added new `failure' client operation. Application is notified about
3906 received failure packet if client is executing a protocol. In this
3907 case the protocol's execution has failed.
3909 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3910 is required by the protocol.
3912 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3913 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3916 * Added status flag to SilcSKE object to indicate realtime status
3917 of the SKE protocol.
3919 * Application receives now exactly same command reply arguments as
3920 the library receives from server. However, if ID is received the
3921 corresponding ID entry is returned to the application (eg. Client
3922 ID is mapped to correct SilcClientEntry entry and that is returned).
3923 Changed command_reply client operation due to this change.
3925 * Changed all ID's in commands and in command replys as ID Payloads.
3926 Change affected both client and server side codes.
3928 All ID's sent in SILC network (with execption of ID's in SILC
3929 Packet header) are sent in ID Payload to support variable length
3932 * Server now notifies nick changes and notifies all clients on
3933 the channels about the new nickname (about the new Client ID,
3936 * Implemented CMODE command to change channel modes. Supports all
3937 channel modes defined by the protocol specs except ban and invite
3938 lists. (Also, private channel key mode is supported but support for
3939 setting private channel key in client is missing, thus, this mode
3940 has no effect on client side (except that server requires that the
3941 client uses private channel key and normal channel traffic does not
3944 Also, invite mode works per se, but INVITE command does not work
3945 yet correctly, so you can set channel as invite only channel but
3946 inviting clients to the channel does not work (it is yet to be
3947 thought what's the best way to do it).
3949 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3950 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3951 Implemented CUMODE command to change user's mode on the channel.
3952 Supports all modes defined by the protocol specs.
3954 * Added NAMES command reply to return users modes on the channel.
3956 * Removed unnecessary and slow ciphers from lib/silccrypt.
3958 * Set SO_KEEPALIVE option to connection sockets by default.
3960 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3962 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3963 redefined the Notify Payload into protocol specs.
3965 * Added silc_id_payload_parse_id to get ID directly from raw
3968 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3971 accept searching by Client ID as well.
3973 * Added support for LEAVE and SIGNOFF notify types in client library.
3975 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3976 to parse ID Payload from raw data.
3978 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Added flags parameter into silc_ske_assemble_security_properties
3981 function in lib/silcske/silcske.[ch].
3983 * Changed notify client operation to fit better for notify messages
3984 sent by server. The notify payload received from server is now
3985 passed to the application (after parsing it to SilcNotifyPayload).
3986 It is application's responsibility to retrieve the arguments
3987 from the payload and show the message the way it wants. The message
3988 sent by server is implementation specific.
3990 * Changed public keys to comply with the protocol specification.
3991 Old public keys are not supported anymore and are not compatible.
3993 * Removed nickname from Channel Payload as the latest draft removed
3994 it. The client must resolve the nickname from the NAMES command
3995 reply received when it joined the channel.
3997 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3999 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Fixed some errors in protocol specification drafts.
4003 * Created lib/silccore/silcnotify.c to implement Notify Payload
4004 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4005 generic payloads described by protocol specifications. The file
4006 includes implementations for ID Payload and Argument Payload.
4008 * Changed Command Payload implementation to use the new Argument
4009 Payload. Changed command_xxxx_payload to command_payload_xxxx
4010 to comply with SILC coding conventions.
4012 * Added suppport for Argument Payload handling in Notify Payload
4013 implementation as protocol requires it. Added the new support
4014 into server and client lib as well.
4016 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4018 * Added support for multiple nicknames on same channel. [n] is
4019 added locally to the nickname if there are more than one same
4020 nicknames on the channel.
4022 * Server now sends all nicknames that matched WHOIS request.
4023 Client also shows the list received from server.
4025 * Added TOPIC command to client side. User can now set and show
4026 current topic on channel.
4028 * Added MOTD command to client and server. Also, server sends the
4029 motd when client connects to the server.
4031 * Changed version strings to comply ISO 8601.
4033 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Fixed protocol error handling in client library. It should now
4036 cope even if the SKE fails for some reason.
4038 * Made new protocol specification drafts for submitting to IETF.
4040 * Implemented TOPIC command to server in silcd/command.c.
4042 * Added two new notify types into lib/silccore/silcnotify.h:
4043 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4044 notify nickname change and topic setting/change on a channel.
4046 * API change of command_reply operation in client library. The
4047 application gets now the status type received from server as well.
4049 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4053 * Cras fixed and optimized the packet handling even further and
4054 it should work now. Minor change to the prototype of function
4055 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4057 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4059 * Added new function into lib/silcutil/silcschedule.[ch]:
4060 silc_schedule_with_fd to select() a specified fd. The function
4061 returns after timeout expires or data arrives or goes. The
4062 function is used by packet routines to wait that all data is
4063 received from network.
4065 * Fixed data reading from network in lib/silccore/silcpacket.c.
4066 The code now assures that all data is read from the fd and then
4067 continues packet processing. This was a bug fix since the code
4068 used to drop some data in some circumstances.
4070 * Added new function into lib/silcclient/client.[ch]:
4071 silc_client_start_key_exchange to start key exchange after
4072 connection has been established to server. The code internally
4073 now uses this funtion but its main purpose was to provide it
4074 for applications that perform their own connecting. After
4075 application has created a connection it merely calls this
4076 function to start the key exchange between client and server.
4077 The library takes care of everything else after that.
4079 Updated also lib/silcclient/README to explain the usage of
4082 * Do not send to application information that connection has
4083 been established. Application gets notified it by connect
4086 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Applied cras's patch to add silc_schedule_one function. The
4089 function runs scheduler once and returns.
4091 * Fixed the scheduler after cras messed it up. The timeout
4092 handling works now as it's supposed to work.
4094 * Added into lib/silccore/ silcnotify.h to include notify
4095 message types support. Changed silc_server_send_notify*
4096 functions, in server.[ch], to support those new notify types.
4097 Added the support for the notify types into client library,
4098 as well. Added new notify client operation into ops.h in
4101 * Changed silc_server_packet_send_to_channel to send normal
4102 packets instead of just channel message packets. The function
4103 is now used to send the notify packets to channels. It is not
4104 used to send channel message packets anymore, as server never
4107 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4108 va_arg()s as it seems to require it nowadays. I guess, if SILC
4109 is compiled with older va_arg() the new code should work anyway.
4111 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Splitted core library. Core library (lib/silccore) includes
4114 now only SILC protocol specific core (and common) components.
4115 Created new utility library (lib/silcutil) that includes more
4116 generic purpose stuff. The stuff for util library was taken
4117 from the old core library. This was minor and easy split.
4119 * Created SILC Client Library (lib/silcclient) that includes
4120 implementation of the SILC client without user interface. This
4121 was major move from silc/ directory. The code has been changed
4122 so that it is transparent towards the user interface. The
4123 silc/ directory includes now the same user interface as before
4124 and it uses the new client library. Read lib/silcclient/README.
4125 Basicly, the client library performs everything else related
4126 to SILC except user interface handling. Also, configuration
4127 files are considered to be part of user interface and library
4128 does not handle them.
4130 This change also changed a lot of structures, function naming etc.
4131 Most important change was that SilcClientWindow object was
4132 renamed to SilcClientConnection in the client library. Created
4133 also new file lib/silcclient/ops.h. Also added new files
4134 silc/local_command.[ch] and silc/client_ops.[ch].
4136 All these changes were made to make it easier for user interface
4137 designers to create what ever user interface for the SILC client
4140 It is also expected that the server will be moved to lib
4141 directory as well and SILC Server Library will be created;
4142 sometimes in the future.
4144 * Removed Local commands from lib/silccore/silccommand.h as
4145 they are application specific and new client library does not
4146 handle any of those anymore.
4148 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4149 old client implementation in silc/.
4151 * Added support for callback functions in SILC_LOG_* macros.
4152 Application can now set its own callbacks that will be called
4153 instead of using the default functions that will always print
4154 the debug messages to stderr (or stdout). Also, debugging can
4155 now be disabled by setting silc_debug to FALSE and re-enabled by
4156 setting it to TRUE. Note, that logging will still work even
4157 if debugging is disabled.
4159 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4160 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4161 silc_log_reset_debug_callbacks.
4163 * To enable debugging in silc client one must give now -d
4164 option on command line.
4166 * Changed silc_schedule_init to automatically allocate task queues
4167 if they are not allocated before calling it.
4169 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Added GMP 3.1 into math library.
4173 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4176 a channel in SILC network. The packet is used by servers and
4177 routers to notify other routers that user has left a channel.
4178 This little feature was missing until now. Added the feature
4179 to protocol specification as well.
4181 Added functions: silc_server_send_remove_channel_user and
4182 silc_server_remove_channel_user into server.[ch].
4184 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4185 lib/silccore/silcpacket.h. However, they are not implemented
4188 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * Fixed joining to a channel and sending channel messages
4191 between server and router. The channel message sending should
4192 now work inside a cell.
4194 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Fixed the private message sending between server and router.
4197 The private message sending should now work inside a cell.
4199 * Added silc_server_replace_id into server.[ch] to replace
4200 existing ID in the SILC network.
4202 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4203 and silc_idlist_replace_server_id into idlist.[ch] in server.
4205 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Fixed the server to server connections. Server can again now
4208 connect to router. Router to router connections probably does
4211 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Added dynamic protocol registering support. Now protocols can
4214 registered and unregistered on the fly. Patch by cras.
4216 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Added lib/contrib directory to hold routines that some platforms
4219 don't have but are needed by SILC.
4221 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4222 into lin/contrib to provide getopt() and getopt_long() for
4223 those who don't have it.
4225 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Added AWAY command to client. When away message is set and
4228 client receives a private message packet the client automatically
4229 replies to the sender with the away message.
4231 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4232 bug seemed to be the cause of recent problems when compiling
4235 * Added version detection support to SKE protocol specification
4236 and added the new changes to the SKE implementation as well.
4237 There were other minor changes in the SKE protocol as well.
4239 Many changes in lib/silcske/silcske.[ch] and in
4240 lib/silcske/payload.[ch].
4242 * Added ^U functionality, clear input line. Patch from cras.
4244 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4246 * Mainly small bugfixes on core library. Fixed some debugging
4247 logging and buffer overflow in silclog.c.
4249 * Updated config.sub and config.guess on the distribution tree.
4251 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4253 * Added command lagging support in server. Client may execute
4254 commands now only once in two seconds.
4256 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Optimized packet reception. MAC computation and checking is now
4259 also more optimized. A lot previously duplicated code is now
4260 used as generic by both client and server.
4262 * Fixed key pair generation in clientutil.c
4264 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Added into lib/silccore/silcbufutil.[ch] new function;
4267 silc_buffer_realloc.
4269 * Moved generic packet sending/encryption functions to
4270 lib/silccore/silcpacket.[ch] from client and server. Some
4271 rewriting of the functions.
4273 * Moved all generic packet reception/decryption functions to
4274 lib/silccore/silcpacket.[ch] from client and server. The
4275 packet processing is now much cleaner in both client and server.
4276 These were major changes in both client and server.
4278 * Created many common functions in server to do packet sending.
4279 Previously code were duplicated a lot, this has been removed
4282 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Rewrote major parts of the ID cache system. Don't know
4285 whether it is better now or not but at least the API is more
4288 * Major rewrite on ID cache stuff on client because of the ID
4289 cache API changes. Added idlist.c to client.
4291 * Also major rewrite on ID cache stuff on server as well.
4292 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4293 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4294 in hand, instead they are all put into the ID cache system now.
4295 All server_idlist_* routines uses ID cache now instead of
4296 traversing its own lists (those lists does not exist anymore).
4297 SilcIDList though still exists. Also, SilcXXXEntry's are
4300 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Finally made the SKE implementation compliant to the protocol
4303 specification. All mp integers are now binary encoded as
4304 opposed being HEX encoded.
4306 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4309 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4310 functions: silc_[encode/decode]_pem. Also added function
4311 silc_encode_pem_file to PEM encode with newlines ('\n') for
4314 * SILC public keys are now encoded either PEM or binary. Same
4315 option is for private keys as well. By default private keys
4316 are binary encoded and public keys PEM encoded. Silly HEX
4317 encoding were removed.
4319 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4320 function to create fingerprints.
4322 * Fixed a bug in SHA1; does not change the original data anymore.
4324 * Partly implemented INFO command on client and server side.
4325 Fixed CLEAR command. Changes to SERVER command; show current
4326 server(s) when giving command without arguments. Added
4327 VERSION command to client.
4329 * Added check to server that unregistered connections cannot
4330 execute commands (unless it is specificly allowed).
4332 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Fixed screen refresh.
4336 * Fixed channel joining bug from client. On some circumstances
4337 client tried to join to a channel it had already joined.
4339 * Added public key verification process into client's protocol.c.
4340 The client now verifies the public key from user and saves
4341 it into ~./silc/serverkeys/ directory.
4343 Added into: clientutil.[ch]: silc_client_verify_server_key.
4345 * Changed SKE protocol's silc_ske_initiator_finish function
4346 to accept callback function that verifies the received public
4347 key. Removed old silc_ske_verify_public_key function.
4349 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4352 silc_pkcs_private_key[_data]_set.
4354 * Made the password and public authentication more cleaner in
4355 server's protocol.c.
4357 * Removed historic and obsolete protocol `channel_auth' from
4358 both client and server.
4360 * Removed wrong way of sending command status messages from
4361 server to client in server's command.c. The old way violated
4362 protocol specification.
4364 Changes to silccore/silccommand.[ch]: removed
4365 silc_command_encode_status_payload -> not needed anymore,
4366 changed silc_command_encode_payload_va to accept extra
4367 argument on variable argument list. The argument type must
4368 now be provided to the function. Also, added new function:
4369 silc_command_encode_reply_payload_va which is same as
4370 normal command_encode_payload_va except command status type
4371 is provided as extra argument.
4373 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Added ~./silc directory handling. The directory includes the
4376 public and private keys for the client.
4378 Added silc_client_check_silc_dir, silc_client_create_identifier
4379 and silc_client_load_keys.
4381 * Implemented SILC protocol compliant public key. Added public
4382 and private key saving to and loading from files.
4384 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4385 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4386 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4387 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
