1 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Defined SILC Mutex API and SILC Thread API and implemented
4 them for Unix. Affected files are
5 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
6 lib/silcutil/unix/silcunixmutex.c and
7 lib/silcutil/unix/silcunixthread.c.
9 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
11 * Fixed the silc_server_remove_clients_by_server's channel
12 key re-generation. The hash table handling was incorrect
13 and would not work with many channels. Affected file is
16 * Fixed some memory leaks around the server code.
18 * Rewrote the silc_server_get_users_on_channel to support IPv6
19 based Client ID's. Affected file silcd/server.c.
21 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
22 specification. However, a separate document must be written
23 to define the detailed signing procedure and the payload
24 associated with the flag. Defined the flag to the
25 lib/silccore/silcchannel.h as well.
27 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
29 * Changed the dynamic tables to static size tables in the
30 lib/silccrypt/silchmac.c.
32 * Removed GCC dependencies from the code. A patch by cras.
34 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
36 * Do not show the error "Error receiving packet bla bla"
37 in server if it really was not an error (-2 means that reading
38 is pending). Affected file silcd/server.c.
40 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
42 * Fixed a possible crash in silc_server_remove_clients_by_server
43 in silcd/server.c. Fixed there also some memory leaks.
45 * Fixed the silc_idlist_replace_client_id. It could replace
46 wrong key in the hash table. Affected file silcd/idlist.c.
48 * Do not check whether there are global users on the channel
49 if the channel->global_users is FALSE. Affected functions
50 silc_server_remove_from_one_channel and
51 silc_server_remove_from_channels in silcd/server.c. Also,
52 do not check if the removed client is local as we can be
53 sure that global client was not removed from the channel
54 and checking for global users is not needed.
56 * The silc_server_remove_clients_by_server now re-generates
57 the channel keys correctly for those channels that had
58 clients removed from them. Affected file silcd/server.c.
60 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
62 * Found the reason of random crashes in the server. We weren't
63 ignoring the SIGPIPE signal (which can be sent in write())
64 and it crashed the server. Affected file silcd/silcd.c.
66 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
68 * Assure that sock->user_data is not NULL in the function
69 silc_server_packet_send in silcd/packet_send.c.
71 * Disconnect the remote connection if it could not be added
72 to any ID lists in the server. The affected file is
75 * Check in silc_server_packet_send[_real/dest] that the
76 socket is not disconnecting and ignore the data if it is.
77 Affected file silcd/packet_send.c.
79 * Define inline to __inline on native WIN32 compilation.
80 Affected file includes/silcwin32.h.
82 * Added some explicit type casts for inline code since MSVC
83 require them. Affected files lib/silcutil/silcbuffer.h,
84 lib/trq/silcdlist.h and lib/trq/silclist.h.
86 * Print warning in log files from now on if the packet
87 decryption fails. Affected file silcd/server.c.
89 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
91 * Changed the `say' client operation's interface to accept
92 new `type' argument to indicate the type of the message sent
93 by the library. The application may filter the library's
94 messages according the type. The affected file is the
95 lib/silcclient/silcapi.h.
97 * Added two new functions to lib/silcclient/silcapi.h:
98 silc_client_del_client and silc_client_del_client_by_id.
99 Affected file lib/silcclient/idlist.c.
101 * Moved the clientincludes.h from includes/ to silc/ and
102 serverincludes.h from includes/ to silcd/.
104 * The modes for the CMODE and CUMODE are now passed as
105 uint32 for application with COMMAND_REPLY. The affected
106 file is lib/silcclient/command_reply.c.
108 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
110 * /WHOIS without arguments shows client's own information.
111 Affected file lib/silcclient/command.c.
113 * Changed PING to not accept any arguments. The specs
114 says that client can ping only the connected server so
115 requiring an argument is not needed. Affected file is
116 lib/silcclient/command.c.
118 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
120 * Fixed a fatal bug in private message sending and reception
121 encryption and decryption when using private message keys.
122 The implementation was incorrect and did not follow the
123 specification. It causd that some of the message were
124 lost since it did not use the sending and receiving keys
125 as the protocol suggests. This has been fixed and will cause
126 incompatibilities with older clients when sending private
127 message encrypted with private message keys. Affected files
128 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
129 and various other in Irssi SILC Client.
131 Added `responder' boolean argument to the functions
132 silc_client_add_private_message_key[_ske] to indicate when
133 the key is added as responder or initiator of the key
136 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
138 * Removed the silc_ske_check_version function and created
139 a SilcSKECheckVersion callback. Added also a function
140 silc_ske_set_callbacks that is now used to set all SKE
141 callbacks. The callback functions are not given to
142 the SKE functions anymore, but this function is used to
145 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
147 * Added `silc_version' argument to the silc_client_alloc
148 to define the version of the application for the library.
149 The library will use the version string to compare it
150 against the remote host's (usually a server) version
151 string. Affected file lib/silcclient/silcapi.h
153 * Added the KE protocol context to Key Agreement context
154 in client library so that we can abort the SKE if it
155 is in process when we get timeout. Affected file is
156 lib/silcclient/client_keyagr.c.
158 * Do not resolve the client ID forever if it returns in the
159 first time that such client does not exist. This was done
160 for example with private message. Affected file is
161 lib/silcclient/client_prvmsg.c.
163 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
165 * Do not add regex.h for WIN32. The affected file
166 includes/silcincludes.h.
168 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
169 not work yet 100%. It generates the DLL's automatically
170 when compiling with --with-win32 under cygwin.
172 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
174 * lib/contrib/regex.c is not compiled on WIN32.
176 * Added silc_net_get_socket_opt function to the
177 lib/silcutil/silcnet.h.
179 * Added includes/silcwin32.h for WIN32 specific includes
182 * Do not use ptime structure or any of the posix process
183 functions on WIN32 in lib/silccrypt/silrng.c.
185 * Added silc_gettimeofday to provide generic function
186 for struct timeval on all platforms. Added the function
187 to lib/silcutil/silcutil.h.
189 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
191 * Moved the lib/silccore/silcsockconn.[ch] to the utility
192 library as they clearly belong there. As a plus side we
193 can make the actual socket connection routines platform
196 Added also new generic function silc_socket_read and
197 silc_socket_write (that used to be silc_packet_[read/write].
198 The implementation of these are platform specific.
200 * Added WIN32 specific routines of silc_socket_[read/write]
201 to lib/silcutil/win32/silcwin32sockconn.c.
203 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
205 * Added preliminary support for native WIN32 compilation under
206 cygwin (using the -mno-cygwin option for GCC) to the
207 ./configure.in.pre. The --with-win32 now prepares the
208 compilation for native WIN32.
210 * Rewrote the SILC Scheduler interface in the file
211 lib/silcutil/silcschedule.h. The scheduler is now context
212 based and does not have anymore any global static scheduler.
213 Moved the Unix scheduler to the lib/silcutil/unix/ directory
214 and created lib/silcutil/win32 directory for WIN32 based
217 * Added Unix specific network routines to the
218 lib/silcutil/unix/silcunixnet.c and the old
219 lib/silcutil/silcnet.c includes now only generic routines.
221 Added WIN32 specific network routines to the
222 lib/silcutil/win32/silcwin32net.c.
224 * Added Unix specific utility functions from the
225 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
227 * Added WIN32 SILC Scheduler to the file
228 lib/silcutil/win32/silcwin32schedule.c. The code is of course
231 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
233 * Do not handle JOIN notify in the server if the target client
234 is not registered (idata->registered == FALSE). The affected
235 file is silcd/packet_receive.c.
237 * Update the nickrec->founder in event_cumode in the Irssi SILC
238 client. Affected file irssi/src/silc/core/silc-channels.c.
240 * Fixed the CUMODE_CHANGE notify handling in the server when
241 server and router are announcing their clients on channels.
242 Now the mode changes are saved and notified correctly. The
243 affected file is /silcd/packet_receive.c.
245 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
246 They really did not replace the cache entry in the ID Cache.
247 Now they do that. Affected file silcd/idlist.c.
249 * Fixed the KICK notify handling in the Irssi SILC client to
250 update the channel records so that the kicked client does not
251 appear to be on the channel. The affected file is
252 irssi/src/silc/core/silc-channels.c.
254 * Always update the conn->current_channel when executing command
255 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
257 * Fixed the KILL notify handling in Irssi SILC client to remove
258 the killed client on all channels.
260 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
262 * Fixed the silc_parse_command_line to remove extra spaces
263 from the start and end of the arguments. Affected file is
264 lib/silcutil/silcutil.c.
266 * Cancel and free any active protocol in the function
267 silc_server_close_connection. Affected file silcd/server.c.
269 * Cancel and free any active protocol in the function
270 silc_client_close_connction. Affected file is
271 lib/silcclient/client.c.
273 * Do not execute the KILL command for clients that are in
274 history (ie. they are not in the network). Affected file is
277 * Fixed KILL notify handling, client does not crash anymore.
278 Affected file irssi/src/silc/core/silc-channels.c.
280 * Reduced the default packet buffer size from 2048 to 1024 in
281 lib/silccore/silcpacket.c.
283 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
284 counter to the SKE context that is incresed when the SKE library
285 performs async operation outside the library. If the outside
286 process frees the SKE context and FREED status will be set
287 and the library will detect after the sync operation that the
288 libary is freed. The affected files are
289 lib/silcske/silcske[_status].[ch].
291 * Resolve the client entry information in the function
292 silc_client_channel_message to assure that NULL pointer is not
293 passed as client entry to the application. */
295 * Fixed the task timeout calculation to assure that there is
296 never negative timeouts. The affected file is
297 lib/silcutil/silcschedule.c.
299 * Fixed the channel user mode notification sending in server.
300 It was sent point-to-point to the router (or to server by router)
301 but it needs to be destined to a channel. The routines now
302 supports sending the channel user mode notifys to the channels
303 when announcing clients and channels. Affected files are
304 silcd/server.c and silcd/packet_receive.c.
306 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
307 It did not actually replace the old channel entry in the cache.
308 Affected file lib/silcclient/client_notify.c.
310 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
312 * Fixed a possible crash in silc_packet_send_prepare. It now
313 assures always that there is enough space in the buffer and
314 at the tail area of the buffer (for MAC).
316 Fixed the inbound buffer reallocation in silc_packet_read.
317 It was old code and did not handle the reallocation correctly.
320 The affected file is lib/silccore/silcpacket.c.
322 * Fixed buffer overflow in silc_parse_nickname in the file
323 lib/silcutil/silcutil.c.
325 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
327 * make install generates new server keys only if there is not
330 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
332 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
333 Added check that if the NOREPLY is set then we will not send
334 the away message. This avoids infinite loop of away messages
335 if both clients are away. The affected file is
336 lib/silcclient/client_prvmsg.c.
338 * Fixed client crash if /NICK was given without arguments.
339 Affected file lib/silcclient/command.c.
341 * Server does not send the invite list in INVITE command back
342 to the client if the list was not altered. Added this notion
343 to the protocol spec as well. Affected file silcd/command.c.
345 Fixed possible crash in INVITE command by checking the
346 value of silc_server_get_client_route command.
348 * Fixed the INVITE notify type handling. The arguments are now
349 taken in correct order and client does not crash. The affected
350 file is irssi/src/silc/core/silc-channels.c.
352 Removed the "Inviting xxx to channel" message from the
353 client library away and let the application handle it.
354 Affected file lib/silcclient/command.c. Added that message
355 to Irssi SILC client's message formats.
357 * Fixed CMODE command crash in client. It now checks the
358 amount of arguments correctly and does not crash. The affected
359 file is lib/silcclient/command.c.
361 * Do not create new channel automatically in silc_channels_join
362 but check whether the channel by that name already exists.
363 Affected file irssi/silc/core/silc-channels.c.
365 * Do not send the SERVER_SIGNOFF to router if the disconnected
366 entity was the router. Affected file silcd/server.c.
368 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
369 SILC client as it was missing from there.
371 Added the handling of the KICK notify to the Irssi SILC client
372 as it was missing. Added "you have been kicked" message to
373 Irssi SILC client's message modules formats.
375 Added the handing of the KILL notify to the Irssi SILC client
376 as it was missing. Added the kill message module formats
379 The affected file is irssi/src/silc/core/silc-channels.c.
381 * The router did not save the channel mode the server announced.
382 Affected file silcd/packet_receive.c.
384 * Fixed a possible crash in INFO command in server. If the
385 server did not provide the server info it crashed. Affected
386 file silcd/command.c.
388 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
390 * Fixed the GETKEY command in the server to check also the
391 global list. Otherwise the GETKEY would not work correctly
392 in normal SILC server. Affected file silcd/command.c.
394 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
396 * Fixed GETKEY crash, it crashed if the command did not succseed.
398 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
401 is now real and not just an macro interface to GMP.
403 Removed the entire GMP from the source tree and imported new
404 NSS MPI library instead. Reason for removing GMP is that it is
405 extremely large and compiles extremely slow. The NSS MPI
406 is only a few files and compiles in less than 10 seconds.
407 The speed is also about the same as GMP. The MPI is imported
410 If the system has GMP installed we will still use the GMP.
411 If it is not then the NSS MPI will be compiled.
413 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
415 * Merged a long nickname (127 characters long) crash bugfix from
416 Irssi CVS tree. Affected file irssi/src/core/misc.c.
418 * Merged a freed memory reference bugfix from Irssi CVS tree.
419 Affected file irssi/src/core/commands.c.
421 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
423 * Added the server's public key sving and verification to the
424 server when performing the SKE. This was missing and the
425 remote server's (or router's) public key was accepted without
426 checking whether we have it previously or trust it at all.
427 Affected file silcd/protocol.c.
429 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
431 * Check in the silc_server_timeout_remote if protocol is active
432 and make sure that the protocol's final callback is called so
433 that all memory if freed. Affected file silcd/server.c.
435 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
437 * silc_server_whois_send_reply crashed the server if the nickname
438 was 127 characters long. Affected file silcd/command.c.
440 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
442 * Added sanity check to the silc_server_new_client. If the hostname
443 is provided inside username then check that the provided hostname
444 really is the same as the resolved one. If the hostname was not
445 resolved then check it from the public key. Affected file is
446 silcd/packet_receive.c.
448 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
449 if the server disconnected us and the connection is not valid
450 anymore. Affected file irssi/src/silc/core/silc-channels.c.
452 * Moved the silc_client_[chmode|chumode|chumode_char] away from
453 the library to the lib/silcutil/silcutil.[ch].
455 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
457 * Close log file after open. Affected file
458 lib/silcutil/silclog.c.
460 * Check whether sock == NULL in silc_client_send_packet and return
461 if it is. Affected file lib/silcclient/silcclient.c.
463 * Check rec->entry == NULL in the Irssi SILC Client before
464 sending the channel message. Affecte file is
465 irssi/src/silc/core/silc-servers.c.
467 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
469 * Merged a splitted window bugfix from Irssi CVS tree. The
470 affected file is irssi/src/fe-text/textbuffer-view.c.
472 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
473 It did not print nickname.
475 * Improved the distributions system a bit.
477 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
479 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
480 irssi/src/fe-text/gui-window.c.
482 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
483 to in-active server. The affected file is
484 irssi/src/silc/core/client_ops.c.
486 * Resolve the client in USERS command reply if the entry does
487 not have username resolved. The affected file is
488 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
489 command to WHOIS command to really resolve stuff. The USERS
490 is not used any more in any critical section so WHOIS can
491 be used even though it might be slower than IDENTIFY.
493 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
496 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
498 * Changed the protocol API a bit more consistent in the
499 lib/silccore/silcprotocol.[ch].
501 * Changed the following headers to ROBODoc format:
503 lib/silccore/silcpayload.h
504 lib/silccore/silcprotocol.h
505 lib/silccore/silcsockconn.h
507 All core library headers are now formatted.
509 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
511 * Fixed a bug in Irssi SILC client; do not show that you are
512 server/router operator if you really are not. Affected file is
513 irssi/src/silc/core/client_ops.c.
515 * Renamed silc_command_free_payload to silc_command_payload_free.
516 Affected file lib/silccore/silccommand.h
518 * Added silcmath.h to include the prototoypes of various routines
519 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
522 * Changed the following headers to ROBODoc format:
524 lib/silccore/silcchannel.h
525 lib/silccore/silccommand.h
526 lib/silccore/silcid.h
527 lib/silccore/silcidcache.h
528 lib/silccore/silcmode.h
529 lib/silccore/silcnotify.h
530 lib/silccore/silcpacket.h
531 lib/silcmath/silcmath.h
533 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
535 * Added checking to the server code not to start the server if
536 ciphers and stuff are not configured properly. Affected files
537 silcd/serverconfig.[h] and silcd/server.c.
539 * Changed the layout of the header files of the public interfaces
540 in the SILC libraries. The new layout supports ROBODoc
541 documentation tool (and some others) so that it is easy to create
542 a library reference manual. All the other headers and source
543 code must still follow the CodingStyle document. Also source
544 code must not include these ROBODoc stuffs, only the headers.
545 Furthermore, all public interface headers must now be named
546 by using `silc' prefix, example: silcapi.h, silccipher.h.
547 Some files were renamed due to this. All the other headers
548 must not be used as public interfaces. I will update the
549 CodingStyle document later. Changed following headers, so far:
551 lib/silcclient/silcapi.h

556 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
560 * Removed silc_client_packet_send_flush from the client library
561 as it is not needed. Affected file lib/silcclient/client.[ch].
563 * Added printing of message of unresolved authentication method
564 to the Irssi SILC client. Added it to the module formats.
565 Removed the same message from the client library.
567 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
569 * Added new distribution feature, DISTLABEL. Every distribution
570 can define own preprocessor label that can be used in the
571 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
572 file distributions, acconfig.h.pre and prepare.
574 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
576 * Added Makefile.defines_int to include the actual definitions
577 for Makefile.defines.in. Tested the new distribution system,
578 created distributions and tested installation.
580 * Added AWAY message printing to the Irssi SILC client. Added
581 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
583 * Added SCONNECT command to call the SILC's CONNECT command.
584 Cannot use CONNECT directly since Irssi uses that internally.
585 Affected file irssi/src/silc/core/silc-servers.c.
587 Added ACTION local command. It is same as ME command but takes
588 the channel as mandatory argument.
590 Rewrote some of the Irssi's help files to suite for SILC
593 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
595 * Added Makefile.defines[.in] that should for now on be included
596 in all Makefile.am file in the source tree. That file includes
597 all common compilation definitions for SILC source tree.
599 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Minor changes to the ./prepare script to change the package
602 name according the distribution name to the configure.in.
604 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
606 * Created new distribution system. Added file `distributions'
607 that defines all the distributions that can be created out of
608 the SILC source tree. The ./prepare script now reads that
609 file to determine how to prepare the distributions. The
610 first argument to the ./prepare is the name of the distribution
611 and second is the version of the distribution. If given
612 without arguments it creates the default (toolkit) distribution
613 with the default version (defined in ./prepare).
615 All Makefile.am files that are subject to the distributions
616 are now named as Makefile.am.pre. These are ./Makefile.am
617 and lib/Makefile.am. Others may be changed later.
619 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
621 * Added invite list, ban list, some key management and connection
622 error message printing to module formats in the Irssi SILC client.
624 * Added new silc_client_set_away_message to set the away message
625 that is back to the person who sent private message. The
626 affected file lib/silcclient/silcapi.h and the
627 lib/silcclient/client_prvmsg.c.
629 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Fixed the private message sending in the Irssi SILC client,
632 added local command KEY to the Irssi SILC client.
634 Added key management and key agreement message formats to the
635 irssi/src/fe-common/silc/module-formats.[ch].
637 Added USERS (alias WHO) printing, server/router operator
638 indication and LIST command printing to the module formats.
640 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
642 * Fixed channel joining notify handling, cumode notify handling
643 from Irssi SILC client.
645 * Added SILC specific module-formats to the Irssi SILC client so
646 that SILC specific message hilighting, colors etc is possible.
647 Affected file irssi/src/fe-common/silc/module-formats.[ch].
649 Added channel mode, channel user mode, actions, notices,
650 whois and whowas printing to the the module-formats.c.
652 * Fixed a bug in channel deletion in the server. The channel
653 is not left to the cache even if the channel founder auth mode
654 is set when there are no users anymore on the channel. Affected
657 * The silc_net_localhost now resolves the entire hostname including
658 the domain name. Affected file lib/silcutil/silcnet.c.
660 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
662 * Changed the ask_passphrase client operation to be ascynchronous.
663 It has now a completion callback and a context that the
664 application must call after it has got the passphrase from
665 the user. Affected files lib/silcclient/silcapi.h,
666 lib/silcclient/protocol.c, lib/silcclient/command.c and
669 Added SilcAskPassphrase callback that the application calls
670 to deliver the passphrase to the library.
672 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
673 The public key verification and especially a certificate
674 verification is asynchronous procedure.
676 Added new SILC_SKE_STATUS_PENDING status to indicate the
677 request is pending and a callback will be called to finalize
680 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
681 indicate that remote end did not send its public key (or
682 certificate), even though we require it. Added check for this
683 condition in the SKE. This was a security bug, now fixed.
685 Defined new SilcSKEVerifyCbCompletion callback that is called
686 when the verification process is completed.
688 The affected files lib/silcske/silcske_status.h and
689 lib/silcske/silcske.[ch].
691 * Changed the verify_public_key client operation to be async
692 as well. Defined SilcVerifyPublicKey callback that is used to
693 indicate the success of the public key verification process.
695 Changed the server and client to use the new async client
698 * Changed the Irssi SILC client's internal scheduler to be called
699 twice as many times as it used to be. As a result the client
700 should be a bit faster now. Affected file is
701 irssi/src/silc/core/silc-core.c.
703 * Added support to Irssi SILC client of asynchronous public key
704 verification and passphrase inquiry. Affected file is
705 irssi/src/silc/core/silc-core.c.
707 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Do not say "You have left channel %s" in client library.
710 Moved it to the application. Affected files are
711 lib/silcclient/command.c and silc/client_ops.c.
713 * Fixed silc_client_get_clients. Command context was not
714 duplicated and was freed memory in the callback. Affected
715 file lib/silcclient/idlist.c.
717 * Do not say "you are now talking..." on JOIN command in the
718 client library. The appliation must handle it.
720 * Do not say ".. changed topic to" in command reply in the
721 client libary. The application must handle it.
723 * Fixed TOPIC command sending in the client library.
725 * Fixed a memory leak in silc_client_command_free in the file
726 lib/silcclient/command.c.
728 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Imported a modified version of Irssi client to the source tree.
731 The Irssi will be used to create a new client called
732 Irssi SILC. Imported to irssi/.
734 Added silc_core_init_finish function to the Irssi. Affected
735 file irssi/configure.in.
737 A lot changes in the Makefile.ams around the irssi tree.
739 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * Do not rehash if the new size is same as the old size of the
742 hash table, in the silc_hash_table_rehash*. The affected file
743 lib/silcutil/silchashtable.c.
745 * Replaced hash_table_del_by_context calls from the server
746 (when channel->user_list and client->channels) to the
747 hash_table_del as it is sufficient and faster.
749 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
751 * Added silc_hash_table_list, silc_hash_table_get and the
752 SilcHashTableList structure to provide an alternative way to
753 traverse the hash table. The affected files are
754 lib/silcutil/silchashtable.[ch].
756 * Changed the server's idlist routines to use the hash table
757 routines to optimize the code.
759 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Replaced the client entry's `channel' list and channel entry's
762 `user_list' list to hash tables for optimized lookup. Changed
763 the code to use the hash table interface around the code.
764 Affected file lib/silcd/idlist.[ch].
766 * Added `auto_rehash' boolean argument to the function
767 silc_hash_table_alloc to indicate whether the hash table should
768 auto-rehash when it thinks is appropriate time. It will
769 increase the hash table size if the there is twice as much
770 entries in the table than the size of the table, and will
771 decrease the size if there are twice as less entries than
772 the size of the table.
774 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Fixed silc_xxx_get_supported to not crash at some circumstances.
778 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
780 * silc_idcache_purge_by_context deletes the entry now by context
781 as it is supposed to do. Affected file lib/silccore/idcache.c.
783 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
784 client is not anymore valid (WHOWAS givens the info) and not
785 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
787 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * Removed the `data' and `data_len' arguments from the ID Cache
790 interfaces and added `name' argument. ID Cache does not handle
791 anymore the binary data only a names associated with given ID.
793 * When hashing a Client ID with silc_hash_id the entire ID is
794 not hashed anymore, instead only the hash of the Client ID is
795 hashed. This way we can access the Client ID from the cache
796 with Client ID but with the hash of the ID (which is a hash of
797 the nickname) as well without any difference in performance.
799 Added also silc_idcache_find_by_id_one_ext to do one on one
800 searching when we have the actual ID. Added also function
801 silc_hash_client_id_compare. The affected files are
802 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
804 * When hashing the name associated with a ID it is always done
805 in lowercase. This way we can access the cache without worrying
806 about case-sensitivity, even though, for example nicknames are
809 * Fixed a bug in server with channel message sending. It put
810 wrong ID type as destination ID. The affected file
813 * silc_idcache_del_by_context now deletes from all hash tables
814 by context. Affected file lib/silccore/idcache.c.
816 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
818 * Changed the client library to use the new ID Cache interface.
819 Changes around the source tree.
821 * Added silc_hash_table_rehash_ext to rehash with specific
822 hash function. Affected file lib/silcutil/silchashtable.[ch].
824 * Added silc_hash_string_compare to compare two strings in the
825 hash table. Affected file lib/silcutil/silcutil.[ch].
827 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Added new function silc_idcache_del_by_context into the
830 lib/silccore/idcache.[ch].
832 * Changed the server's ID list routines to use the new ID Cache
833 interface. Changes around the source tree.
835 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
837 * Added silc_hash_table_del[_by_context]_ext functions in to the
838 lib/silcutil/silchashtable.[ch].
840 Removed silc_hash_table_find_all* routines and added new
841 silc_hash_table_find_foreach to replace them.
843 Added silc_hash_table_replace_ext function as extended
844 replacing function. Separated the simple hash table interface
845 from the extended hash table interface in the file
846 lib/silcutil/silchashtable.h.
848 * Fixed minor bugs and changed it to use some of the new
849 hash table functions in lib/silccore/idcache.c
851 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
853 * Added new function silc_hash_table_find_all to return all keys
854 in the hash table by the specified key. As the hash table is
855 collision resistant it also makes it possible to have several
856 duplicate keys in the hash table. This function may be used to
857 find all of the keys from the hash.
859 Added user_context arguments to the SilcHashFunction,
860 SilcHashCompare and SilcHashDestructor to deliver user specified
863 Added new fuctions silc_hash_table_find[_all]_ext to do
864 extended lookup with specified hash and compare functions and
865 specified user contexts.
867 Added new function silc_hash_table_add_ext to add the key
868 with specified hash function and user context.
870 Added new function silc_hash_table_foreach to traverse all
871 entrys in the hash table. Added SilcHashForeach callback
874 Added new function silc_hash_table_del_by_context to delete
875 the entry only if the context associated with the key matches.
877 Affected files are lib/silcutil/silchashtable.[ch].
879 * Removed silc_hash_[server/client/channel]_id and added just
880 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
881 silc_hash_id_compare to compare two ID's using as the hash table
882 comparison function. Added also silc_hash_data to hash
883 binary data and silc_hash_data_compare to compare it.
885 * Removed silc_idlist_find_client_by_hash as it is not needed
886 anymore. Affected file silcd/idlist.[ch].
888 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
889 to use internally the SilcHashTable. The new ID Cache is a lot
890 faster than the old one. Some of the ID Cache interface was also
891 rewritten and obsolete and stupid functions were removed.
893 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
895 * Added entry_count field to the SilcHashTable to keep the number
896 of the entries in the table. Implemented the function
897 silc_hash_table_rehash. Added new function
898 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
900 Fixed a minor bug in silc_hash_table_free.
902 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
903 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
904 into the lib/silcutil/silcutil.[ch].
906 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
908 * Implemented a collision resistant hash table into the
909 lib/silcutil/silchashtable[ch]. See the header and the source
910 for the SilcHashTable API.
912 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Merged dotconf version 1.0.2 into lib/dotconf.
916 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
918 * Do not compile anything in lib/silcsim/* if the SIM support
919 is not enabled. The tree should now compile without problems
922 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
924 * Compiled the SILC under cygwin. Compiled and tested briefly
925 without problems. More tests needed. The SIMs didn't compile
928 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
930 * Fixed possible crash in silc_get_username in the
931 lib/silcutil/silcutil.c.
933 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
935 * Fixed a va_arg in silc/client_ops.c.
937 * Oops, RC5 routines were named AES and caused some problems
938 when not using SIM's. Affected file lib/silccrypt/rc5.c.
940 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
942 * Added new SilcIDIP structure into the lib/silccore/id.h and
943 replaced the old `ip' fields from all SILC ID's to that type.
944 This is a step towards IPv6 support.
946 The silc_id_get_len takes now the ID as an extra argument.
947 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
948 both IPv4 and IPv6 based ID's.
950 The affected files are lib/silccore/id.[ch] and other files
951 around the tree using these routines.
953 * Removed the ID length arguments in server from various
954 silc_server_send_notify_* routines -> they are not needed
957 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
959 * Fixed memory leak in silc_encode_pem_file in the file
960 lib/silcutil/silcutil.c.
962 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
964 * Check minor version as well in the SKE. Affected files are
965 silcd/protocol.c and lib/silcclient/protocol.c.
967 * Added --identifier option to the server so that an identifier
968 can be when creating the public key for the server. Affected
969 file is silcd/silcd.c.
971 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
972 lib/silccrypt/silcpkcs.c.
974 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
976 * Register default ciphers and stuff when using -C option with
977 the server. Affected file sildc/silcd.c.
979 * Put back the servers public key filename format, it is better
980 than the new one. For now, the client keys are saved with the
981 new filename format. The affected file silc/client_ops.c.
983 * Implemented the Cipher API for the rest of the ciphers that
984 did not implement it or implemented it the wrong way.
986 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
988 * Register default ciphers and stuff when using the -S option
989 in the client. Affected file silc/silc.c. Same also when
990 creating new key pair with -C option.
992 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * Fixed the silc_verify_public_key client operation function to
995 save the public keys differently. The fingerprint is now
996 used as filename and not the hostname. This way also the
997 client keys are saved uniquely and not with hostnames. The
998 affected file is silc/client_ops.c.
1000 * Trimmed the silc_hash_fingerprint function to remove extra
1001 whitespaces from the end of the fingerprint. The affected
1002 file is lib/silccrypt/silchash.c.
1006 * Added silc_cipher_register_default function to register all
1007 default ciphers. It can be used when configuration files
1008 does not exist and the application does not want any specific
1009 ciphers in any specific order.
1011 The SilcDList is now used as silc_cipher_list dynamically
1012 allocated cipher list. Removed the static list all together
1013 and now all ciphers must be allocated to the dynamic list.
1014 The silc_cipher_alloc routine was changed to check only the
1017 All silc_cipher_* routines that used to return int returns
1020 The affected files lib/silccrypt/silccrypt.[ch].
1022 * The same thing was done to silc_hash_* as for silc_cipher_*
1023 routines. Affected files lib/silccrypt/silchash.[ch].
1025 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1026 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1027 Added also silc_pkcs_[un]register[_default] functions.
1028 Removed the data_context from the PKCS API.
1030 * Added silc_hmac_register_default function to register default
1031 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1032 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1033 to unregister all hmacs at once.
1035 * Register the default ciphers, hash functions, PKCSs and HMACs
1036 if client's configuration file does not exist. The affected
1039 * The client did not load the hash functions from the SIM
1040 modules at all. Added support for this. Affected file is
1041 silc/clientconfig.c.
1043 * When decoding public key with silc_pkcs_public_key_decode, check
1044 the supported algorithm only if PKCS are registered. Affected
1045 file lib/silccrypt/silcpkcs.c. The same was done with the
1046 silc_pkcs_private_key_decode.
1048 * Fixed the SILC List routines to keep the list always in order.
1049 It used to change the list's order when traversing the list but
1050 not it preserves the order. Affected file lib/trq/silclist.h.
1052 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Added the client library to use the SilcSocketConnection's
1055 reference counter (by silc_socket_dup) to prevent the bug that
1056 the socket object may be freed underneath async operation.
1058 * The name resolv library checking fixes in the configure.in.pre.
1061 * Created new version of the protocol drafts for future
1062 development. The -03 drafts are the ones that will be changed
1063 in the trunk now and the -02 will remain as they are.
1065 * Send list of CUMODE notifys to the router when announcing
1066 the channel users to the router. Affected file silcd/server.c.
1067 If the router receiving channel founder CUMODE for a channel
1068 that already has channel founder it will send CUMODE notify
1069 to the sender to remove the channel founder rights from the
1070 announced client. Affected file silcd/packet_receive.c.
1072 * The CUMODE notify may now use Server ID as well as the entity
1073 who changes the mode. Updated protocool specs.
1075 * Updated INSTALL and README files.
1077 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * New web pages in the http://silc.pspt.fi. The pages was
1084 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1086 * Implemented the [DenyConnectin] config section in the server.
1087 Added silc_server_config_denied_conn to check whether incoming
1088 connection is denied. Affected file silcd/serverconfig.[ch].
1090 * Do not check the ports when checking the incoming configuration
1091 data if the port is 0, meaning any. Affected file is
1092 silcd/serverconfig.c.
1094 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * Fixed buffer overflow in silc_string_compare in the file
1097 lib/silcutil/silcutil.c.
1099 * Fixed double free in silc_server_command_leave in the file
1102 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Fixed the version checking in the server. Affected file is
1107 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Fixed the configuration data fetching when accepting new
1110 connections in the server. Affected file silcd/server.c.
1112 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1114 * Added `sender_entry' argument to the function
1115 silc_server_packet_relay_to_channel so that we can check
1116 whether some destination actually belongs to the same route
1117 the sender belongs (ie, we must not resend the packet to the
1118 sender). Affected file silcd/packet_send.[ch].
1120 * Added `servername' field to the SilcClientEntry in the server
1121 to hold the name of the server where client is from. Affected
1122 file is silcd/idlist.h.
1124 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1126 * Moved the channel message encrypting in the router betwen
1127 router connections from silc_server_channel_message to the
1128 silc_server_packet_relay_to_channel since we want to check
1129 whether we have anybody channel before encrypting anything.
1130 Affected files silcd/packet_[receive/send].c.
1132 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1134 * Fixed the [AdminConnection] server config section to support
1135 multiple entries. Affected file silcd/serverconfig.c.
1137 * Added support into the server to check the validity of the
1138 incoming connection before executing any KE or authentication
1141 * The connection configuration is now saved to the KE and
1142 connection auth protocol contexts and not fetched anymore in
1143 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1145 * The local hosts listenning address and port is also resolved
1146 now when starting the server. We want to have the socket object
1147 to include the real address and port for the listener. Added
1148 new function silc_net_check_local_by_sock into the files
1149 lib/silcutil/silcnet.[ch].
1151 * Fixed a broadcast bug in server -> do not broadcast if we
1154 * Fixed a routing bug. Do not route broadcast packets ever.
1155 Broadcast packets must be processed always and not routed since
1156 they may be destined to some other host than yourself and thus
1157 would get routed without no good reason. Affected file is
1160 * Added function silc_server_config_is_primary_route to check
1161 whether primary router connection has been configured (a router
1162 configuration that we are initiating). If there is not, we
1163 will assume that there is only two routers in the SILC network
1164 and we will use the incoming router connection as our primary
1165 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1167 * Changed the order of the broadcasting. Broadcast _after_ the
1168 packet has been processed not before. Affected file is
1171 * Fixed a [ClientConnection] parsing bug. The port was never
1172 parsed correctly thus resulting to port 0. Affected file
1173 silcd/serverconfig.c.
1175 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1176 argument and did not set the broadcast packet flag. Affected
1177 file silcd/packet_send.c. Fixed same bug in the function
1178 silc_server_send_notify as well.
1180 * If we receive NEW_ID packet for our own ID in the server, ignore
1183 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * Removed the nickname from the Private Message Payload.
1188 Updated the code and the protocol specs.
1190 * Updated protocol specs for submitting to the IETF.
1192 * Tweaked the Random Number Generator a bit. Affected file
1193 lib/silccrypt/silcrng.c. Exported a new function
1194 silc_rng_[global]_add_noise which can be used to add more
1197 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1199 * Do not parse packets with different timeout when protocol
1200 is active -> may cause problem with rekey. Affected file
1203 * When server receives signoff notify it must not create
1204 new channel key if the client is on any channels since the
1205 sender of the signoff notify will create it.
1207 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1209 * Added printing of error messages during SKE protocol from the
1210 failure packet sent by server during SKE. Affected file
1213 * Removed the client's failure_callback handling with timeout
1214 and handle it immediately when received.
1216 * The SKE library returned wrong type in SUCCESS and FAILURE
1217 packets. They must be 32 bit MSB not 16 bit MSB.
1219 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1221 * Ok, rewrote the logic of the re-key and now it seems to work.
1222 I tested it on high traffic with frequent re-keys without
1223 problems. Added hmac_receive (and renamed hmac to hmac_send)
1224 in SilcClientConnection in lib/silcclient/client.h and
1225 in SilcIDListData in silcd/idlist.h. Also, removed the
1226 SilcPacketParserContext's cipher and hmac fields as they are
1227 not needed anymore and actually caused some problems when
1228 the ciphers and hmac's changed underneath the packet parser.
1230 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1232 * If re-key protocol is active then process the incoming packets
1233 synchronously since we must assure that icoming packets encrypted
1234 with the old key is processed before the new keys is set to
1235 use. This is true other packets than for REKEY packets.
1236 Affected file silcd/server.c. The same was done to client library
1237 as well, affected file lib/silcclient/client.c.
1239 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1241 * Fixed bug in client and server to accept the force send if
1242 the packet is send from silc_[server/client]_packet_process
1243 function. Otherwise the packets are never delivered, oops.
1245 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * Disable force sending of packets when REKEY protocol is active.
1248 We must assure that no packet is sent directly when rekey is
1249 performed. All packets must be sent through packet queue.
1250 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1251 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1252 function is silc_[server/client]_packet_send_real to check
1255 * Replaced the SIM paths from example config files to
1256 /usr/local/modules. Also, make install creates now
1257 /usr/local/silc/logs directory to hold all the SILC server
1260 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Made the configure.in.pre work on Solaris. Patch by salo.
1264 * Made all ciphers compatible with non-x86 machines. Defined
1265 CBC mode macros into lib/silccrypt/ciphers_def.h.
1267 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1269 * Fixed the make install.
1271 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1273 * When MAC computation fails the silc_packet_decrypt returned 0
1274 even though it was supposed to return -1. Fixed this. The
1275 affected file is lib/silccore/silcpacket.c.
1277 * Do not replace the config files in /etc/silc (in make install)
1278 if they already exist. Affected file ./Makefile.am.
1280 * Do not send re-key packets immediately but through packet queue.
1281 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1283 * Changed silc_net_check_host_by_sock to return FALSE if the
1284 IP/DNS could not be resolved. Though, it returns the IP address
1285 now even if it could not resolve it (but returns also FALSE).
1286 Affected file lib/silcutil/silcnet.[ch].
1288 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1290 * Added silc_pkcs_decode_identifier to decode the public key's
1291 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1292 Added also silc_pkcs_free_identifier. Added also new context
1293 SilcPublicKeyIdentifier.
1295 * Added -S option to the silc client. It is used to dump the
1296 contents of the specified public key file.
1298 * Changed the PKCS api to return the public key length when
1299 setting the public key.
1301 * Fixed a fatal bug in the public and private key file loading.
1302 Affected file lib/silccrypt/silcpkcs.c.
1304 * Execute the packet parsing for client with zero (0) timeout
1305 if the protocol is active. Affected file silcd/server.c.
1307 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1309 * Made the key generation options to the silcd program. Added
1310 -C option, equivalent to client's option.
1312 * Added new [ServerKeys] config section to the server. It
1313 configures the server's public and private key.
1315 * Defined generic Public Key Payload into the protocol
1316 specification to send specific type of public keys and
1319 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1320 public key or certificate.
1322 * Implemented the GETKEY command to the server and to the
1323 client library and on user interface.
1325 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Made preliminary `make install' work.
1329 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1331 * Added SilcServerRekey context into silcd/idlist.h.
1333 * Added the PFS support as defined in the specification to the
1334 SKE protocol. Affected files lib/silcske/*.c.
1336 * Added `ske_group' field to the SilcServerRekey context to hold
1337 the number of the SKE group that is used with PFS in re-key.
1338 Affected file silcd/idlist.h.
1340 * Added PFS re-key support to the server. Affected file is
1343 * Added silc_protocol_cancel to cancel execution of the next
1344 state of the protocol. Affected file is
1345 lib/silccore/silcprotocol.[ch].
1347 * Added the re-key support with and without PFS to the client
1348 library. Re-key is performed once in an hour, by default.
1350 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1351 Added silc_client_rekey_callback and silc_client_rekey_final.
1352 Affected files are lib/silcclient/protocol.[ch] and
1353 lib/silcclient/client.[ch].
1355 * Removed the `hmac_key' and `hmac_key_len' fields from the
1356 SilcClientConnection structure; not needed. Affected file is
1357 lib/silcclient/client.h.
1361 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Do not ask whether user wants to use the negotiated private key
1364 for private messages, just use it. Affected file is
1365 silc/local_command.c.
1367 * Added `send_enc_key' and `enc_key_len' fields to the
1368 SilcIDListData structure since they are needed in the re-key
1369 phase. Affected file is silcd/idlist.[ch].
1371 * Implemented the simple re-key protocol into the server.
1372 Affected files silcd/server.c and silcd/protocol.[ch]. The
1373 re-key will be performed once in an hour, by default.
1375 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1376 Added silc_server_rekey, silc_server_rekey_callback and
1377 silc_server_rekey_final.
1379 * Removed Tunneled flag from the protocol. Updated the code
1380 and the specifications.
1382 * Adde `pfs' field to the SilcIDListData to indicate whether
1383 the PFS is to be performed in the re-key. Affected file is
1386 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1389 int64 of at least the xintXX size. If void * is less that 4
1390 bytes uint32 * will be used. Defined bool as boolean.
1392 * Changed _ALL_ unsigned long and unsigned int to uint32,
1393 unsgined short to uint16 in the source tree.
1395 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1396 not handle clients that has entry->data.registered == FALSE.
1397 They are not in the network anymore. Affected file is
1400 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Implemented the sending of the SERVER_SIGNOFF notify in the
1403 server. Affected file is silcd/server.c.
1405 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1406 Added also silc_notify_payload_encode_args into the
1407 lib/silccore/silcnotify.[ch].
1409 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1410 Affected file silcd/packet_receive.c.
1412 * Implemented the SERVER_SIGNOFF notify handling in the client
1413 library. Affected file lib/silcclient/client_notify.c. Also,
1414 implemnted the printing of the SERVER_SIGNOFF info to the
1415 application. Affected file silc/client_ops.c.
1417 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1418 if the deleting was successful. Affected file silcd/idlist.[ch].
1420 * Added support for public key authentication in the connection
1421 authentication protocol in the client library. Affected file
1422 lib/silcclient/protocol.c.
1424 * Changed the server's silc_idlist_get_clients_by_* interface
1425 to support already allocated array so that new entries may be
1426 added to pre-allocated array. Affected file silcd/idlist.[ch].
1427 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1428 and command replies.
1430 * All command reply functions in the server now calls the
1431 pending command callback even if error occured. This way the
1432 error will be delivered to the client as well. Affected files
1433 silcd/command.c and silcd/command_reply.c.
1435 * Fixed INFO command to return local server's info if no server
1436 was provided. Affected file lib/silcclient/command.c.
1438 * Removed RESTART command for good. Updated the code and the
1441 * Rewrote parts of the task system. It is a bit simpler now.
1442 Removed unsued task priorities. The affected files are
1443 lib/silcutil/silctask.[ch].
1445 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Moved the USERS printing from the library to the application.
1448 Affected files lib/silcclient/command.c and silc/client_ops.c.
1450 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1454 * Added channel key re-key support. The re-key is perfomed
1455 only by the router and is done once in an hour. Added `rekey'
1456 field to the SilcChannelEntry in the server. Affected files
1457 silcd/server.c and silcd/idlist.h.
1459 * Added silc_task_unregister_by_context into the file
1460 lib/silcutil/silctask.[ch].
1462 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1464 * Added SILC_UMODE_GONE mode to indicate when the client is not
1465 present in the SILC network. Added also support to the local
1466 command AWAY that will set this mode. Added support of showing
1467 "xxx is gone" in WHOIS command. The USERS command shows the
1468 gone status as well.
1470 * Fixed setting server and router operator privileges in the
1471 server's UMODE command. Affected file silcd/command.c.
1473 * Merged the SKE KE1 and KE2 payloads into one payload. The
1474 new KE payload is equivalent to the old KE2 payload.
1476 Cleaned up the SKE Start Payload parsing. It now uses the
1477 simple buffer unformatting to do the parsing. A lot faster
1480 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1481 to the SKE that is used to indicate whether both of the SKE
1482 parties should perform authentication. By default only the
1483 responder performs authentication. By setting this flag also
1484 the initiator must do authentication. By default it is unset
1485 since in normal SKE case, client to server connection, only
1486 the responder should do authentication. When doing SKE between
1487 two clients both should perform authentication. Updated the
1488 code and the protocol specs.
1490 * A little fix to IDENTIFY command in the server. Search the
1491 client first by hash not nickname. Affected file is
1494 * Fixed the silc_client_close_connection to support closing
1495 the client to client connections wihtout deleting too much
1496 data. Affected file lib/silcclient/client.c.
1498 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1499 are received if protocol used to be active but is not anymore
1500 the application would crash due to NULL pointer dereference.
1501 Affected files silcd/server.c and lib/silcclient/client.c.
1503 * Added `hash' field to the SilcClientConnection to include
1504 the hash function negotiated in the SKE protocol.
1506 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1507 to set the channel founder authentication data. A client can
1508 claim the founder rights later by providing the authentication
1509 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1510 This way the channel founder can regain the channel founder
1511 privileges even it is left the channel. This works only on
1512 local server and the client must be connected to the same
1513 server to be able to regain the founder rights. Updated the
1514 protocol specs accordingly.
1516 Added support to the CMODE command in the client to set the
1517 founder auth data. Read the README to see how to set it.
1519 Added support to the CUMODE command to claim the founder
1520 rights. Read the README to see how to do it.
1522 Added support for the founder authentication to the Channel
1523 Entry in the server. Affected file silcd/idlist.h.
1525 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1526 server's CMODE command. Affected file silcd/command.c.
1528 * Added the following new functions into lib/silccore/silcauth.[ch]:
1529 silc_auth_get_method and silc_auth_get_data.
1531 * The server now saves the remote hosts public key to the
1532 SilcIDListData pointer. Affected file silcd/protocol.c.
1534 * The normal server now does not remove the channel entry from
1535 the cache if the founder authentication data is set. It used
1536 to remove it if the founder was the last one on the channel on
1537 the server and left the channel. The auth data is saved and
1538 if the channel is re-joined later the old entry is used with
1539 the old auth data. Affected files silcd/command_reply.c and
1542 * Removed the `pkcs' field from the SilcIDListData structure
1543 in the server; it is not used. Affected file silcd/idlist.h.
1545 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Fixed packet processing on slow links. Partial packets were
1548 never re-processed because the incoming data buffer was cleared
1549 by the application. Application must not directly clear the
1550 sock->inbuf, the packet processing routines handle it. Fixed
1551 this in client library and in server.
1553 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Fixed the WHOIS and IDENTIFY send reply function to really
1556 check whether to send list or just one entry. Affected file
1559 * Cleaned up the LEAVE command's channel key distribution. The
1560 affected file silcd/command.c.
1562 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1563 can enforce the channel mode as well. In that case the ID
1564 includes the ID of the server. The code now enforces the
1565 mode change if the router have different mode than the server.
1567 * The notify client operation with CMODE_CHANGE notify can now
1568 return NULL client_entry pointer if the CMODE was not changed
1569 by client. Application must check for this.
1571 * Added <Server ID> argument to INFO command to support server
1572 info fetching by Server ID.
1574 * Added silc_server_announce_get_channel_users to get assembled
1575 packets of channel users of the specified channel. Affected
1576 file silcd/server.[ch].
1578 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1579 was freed underneath the ID Cache.
1581 * Re-announce clients when the server received CHANNEL_CHANGE
1582 notify from the router. Affected file silcd/packet_send.c.
1584 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1587 crashed since it did not handle the fact that there is no cipher
1588 called "3" and didn't check the error condition. Now fixed.
1590 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1591 flag. It can be used to send message requests.
1593 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Implemented the RESTART command in the client.
1597 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1598 notice type messages. Added notice printing to the user
1601 * The channel keys are not re-generated if the channel's mode
1602 is PRIVKEY, ie private key on the channel exists. Affected
1603 files silcd/server.c and silcd/command.c.
1605 * Fixed a little bug in channel message delivery when channel
1606 private keys are set in the server. Affected file is
1607 silcd/packet_send.c.
1609 * Changed the setting on channel->on_channel = TRUE from the
1610 silc_client_save_channel_key to the JOIN command reply. The
1611 key payload is not received if the private channel key is set.
1612 Affected file lib/silcclient/command_reply.c and the
1613 lib/silcclient/client_channel.c.
1615 * When the CMODE_CHANGE notify is sent and the channel private
1616 key mode is removed the channel key must be re-generated in
1617 other cells as well. Added this support for the router in the
1618 silcd/packet_receive.c.
1620 * Added new local command NOTICE to send notice message on
1621 channel. Affected file silc/local_command.[ch].
1623 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1625 * Added new local command ME to the client. It is used to send
1626 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1627 some action. Affected file silc/local_command.[ch].
1629 * Changed channel_message and private_message client operations
1630 to deliver the message flags to the application. Added also
1631 the `flags' arguments to the silc_client_send_channel_message
1632 and silc_client_send_private_message functions. Affected file
1635 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1637 * Redefined the Private Message Payload to support private message
1638 keys and to support the new private message flags. Updated
1639 the protocol specs. Flags makes it possible to have for example
1640 CTCP style messages.
1642 * Added new type SilcPrivateMessagePayload and defined an API
1643 for it in the lib/silcclient/silcprivate.[ch].
1645 * Tested private message private keys successfully. Tested the
1646 private message key set, unset and list commands with the new
1649 * Redefined the Channel Message Payload to include the channel
1650 message flags (equal with private message flags) to support
1651 for example CTCP style messages.
1653 * Defined some of the message (for channel and private message)
1654 flags. Updated the protocol specs and added the flags to the
1655 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1657 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1659 * Added SilcKeyAgreementStatus type to the key agreement routines
1660 to indicate the current status and error if one occured.
1661 The status types are defined in the lib/silcclient/silcapi.h.
1663 * Added new local command KEY that is used to set and unset private
1664 keys for channels, set and unset private keys for private messages
1665 with remote clients and to send key agreement requests and
1666 negotiate the key agreement protocol with remote client. The
1667 key agreement is supported only to negotiate private message keys,
1668 it currently cannot be used to negotiate private keys for channels,
1669 as it is not convenient for that purpose.
1671 * Fixed a minor pending callback setting bug in the function
1672 silc_client_get_client_by_id_resolve, now the function works.
1673 Affected file lib/silcclient/idlist.c.
1675 * Added function silc_net_get_local_port to get local bound
1676 port by socket. Added to lib/silcutil/silcnet.[ch].
1678 * Added `sockets' and `sockets_count' fields to the SilcClient
1679 object. They hold the sockets of the listenning sockets in
1680 the client. Listenning sockets may be for example the key
1681 agreement server. Affected file lib/silcclient/client.[ch].
1682 Added functions the silc_client_add_socket and the
1683 silc_client_del_socket. They are exported to the application
1686 * Added ~./silc/clientkeys to support other client's public keys.
1688 * Renamed verify_server_key client operation to verify_public_key
1689 and added one argument to indicate the type of the connection
1690 (server, client etc.).
1692 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Added silc_server_connection_auth_request to handle the
1695 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1696 silcd/packet_receive.[ch].
1698 * Added silc_server_send_connection_auth_request into the
1699 silcd/packet_send.c to send the connection auth request packet.
1701 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1704 * Fixed the public key authentication in responder side in the
1705 server. The `auth_data' pointer includes the SilcPublicKey
1706 not the path to the public key. Affected file silcd/protocol.c.
1708 * Implemented the public key authentication in the initiator side
1709 in the server. Affected file silcd/protocol.c.
1711 * Removed the [RedirectClient] config section from the server
1712 configuration. Is not needed and I don't want to implement it.
1714 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Cleaned up the CMODE command in the server. It now works
1717 correctly and supports all the modes defined in the protocol.
1718 Affected file is silcd/command.c.
1720 * Added `hmac_name' field to the SilcChannelEntry in the server
1721 to hold the default HMAC of the channel. It can be set when
1722 creating the channel (with JOIN command). Affected files
1725 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1726 type to indicate the change of the current cipher and hmac
1727 on the channel. Client can safely ignore the <cipher> argument
1728 (if it chooses to do so) since the CHANNEL_KEY packet will
1729 force the channel key change anyway. The <hmac> argument is
1730 important since the client is responsible of setting the new
1731 HMAC and the hmac key into use.
1733 * Fixed the CMODE command in the client library as well.
1735 * Tested CMODE command in router environment successfully.
1737 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1739 * Show the version of the remote client (or server) when connecting
1740 to the server. It is logged to the log file. Affected file
1741 is silcd/protocol.c.
1743 * Fixed the KILLED notify handling in the client library. The
1744 client must be removed from all channels when receiving the
1747 Also, do not remove the client entry when giving the KILL
1748 command but when the KILLED notify is received.
1750 * Removed silc_idlist_find_client_by_nickname from the server.
1751 Not needed anymore. Affected files silcd/idlist.[ch].
1753 * Implemented the CHANNEL_CHANGE notify type handling to the
1754 server. Affected file silcd/server.c.
1758 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1760 * Added silc_server_send_notify_invite to send the INVITE
1761 notify between routers.
1763 * Implemented the INVITE command correctly to the server.
1765 * Implemented the INVITE notify type handling in the server.
1767 * Implemented the INVITE command to the client library and on the
1770 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Added function silc_server_get_client_resolve to find the
1773 client entry by ID from all ID lists and then resolve it
1774 (using WHOIS) if it cannot be found. Affected file is
1777 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * Implemented the BAN command to the client library.
1781 * The JOIN command in the server now checks the invite list
1784 * Changed the silc_command_reply_payload_encode_va and the
1785 silc_command_payload_encode_va to support that if argument is
1786 NULL it ignores and checks the next argument. Affected file
1787 lib/silccore/silccommand.c.
1789 * Added silc_server_send_notify_ban to send the BAN notify
1790 type between routers.
1792 * Chaned the silc_notify_payload_encode to support that if
1793 argument is NULL it ignores and checks the next argument.
1794 Affected file lib/silccore/silcnotify.c.
1796 * Tested ban lists in router environment successfully.
1798 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1800 * Implemented BAN command to the server, in silcd/command.[ch].
1802 * Removed the BAN and INVITE_LIST modes from the CMODE command
1805 * Added function silc_string_match to regex match two strings.
1806 Affected files lib/silcutil/silcutil.[ch].
1808 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * Redefined parts of the SilcChannelEntry in the server to support
1811 the new ban and invite lists.
1813 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1815 * Redefined the INVITE command. The same command can be used to
1816 invite individuals to the channel but also to manage the invite
1817 list of the channel (to add to and remove from the invite list).
1818 Updated the protocol specs.
1820 * Added new command SILC_COMMAND_BAN that can be used to manage
1821 the ban list of the channel. Updated the protocol specs.
1823 * Removed the channel modes: the SILC_CMODE_BAN and the
1824 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1825 in the CMODE command. The equivalent features are now available
1826 using INVITE and BAN commands. Updated the protocol specs.
1828 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1829 in the network about change in the current ban list. The notify
1830 type is not used by the client.
1832 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1833 support the invite lists.
1835 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Added new function silc_string_regexify that converts string
1838 including wildcard characters into regex string that can
1839 be used by the GNU regex library. Added into the file
1840 lib/silcutil/silcutil.[ch].
1842 Added silc_string_regex_combine to combine to regex strings
1843 into one so that they can be used as one regex string by
1844 the GNU regex library. Added into the file
1845 lib/silcutil/silcutil.[ch].
1847 Added silc_string_regex_match to match two strings. It returns
1848 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1850 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1852 * Imported GNU regex to the soruce tree into lib/contrib.
1853 Fixed some compiler warning from the regex.c.
1855 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1857 * Fixed MOTD command in the server to work in router environment.
1859 * Fixed the MOTD command in the client library to support
1860 the server argument in the command.
1862 * Added `nickname_len' argument to the silc_idlist_add_client
1863 in the server, as the `nickname' argument may be binary data
1866 * Added silc_idlist_get_channels to return all channels from
1869 * Implemented LIST command to the server. Affected file is
1872 * Implemented the LIST command to the client library and on the
1875 * Added [<user count>] argument to the LIST command reply.
1876 With private channels the user count is not shown.
1878 * Updated TODO and README.
1880 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1882 * The client entry's data.registered must be TRUE even with
1883 global client entry on global client list. The data.registered
1884 is used to check whether the client is anymore in the network,
1885 for example with WHOWAS command so it must be valid.
1887 * Fixed the WHOWAS command in the server. It now actually works
1888 in router environment. Added function into silcd/command_reply.c
1889 silc_server_command_reply_whowas_save.
1891 * Added silc_idlist_purge function to the silcd/idlist.c
1892 to periodically purge the ID Cache.
1894 * Fixed INFO command in the server. It works now in router
1895 environment. Added <server name> argument to the INFO command
1896 reply. Updated the protocol specs.
1898 * Fixed minor bug in silc_idcache_purge to not purge if the
1899 expire value is zero.
1901 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1902 they were buggy because of the WHOWAS information.
1904 * Fixed local command MSG to handle the async resolving of
1905 the remote client properly. It used to fail the first MSG.
1906 Affected file silc/local_command.c.
1908 * Added `data_len' field to SilcIDCache context.
1910 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1912 * Update TODO. Todo in commands in the server.
1914 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1917 used by routers as broadcast packet to inform other routers
1918 about the changed user mode.
1920 Implemented the notify handling in the server. Affected file is
1921 silcd/packet_receive.c. Added the function
1922 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1924 * Added new generic Channel Payload and deprecated the New Channel
1925 Payload. The New Channel Payload is now the generic Channel
1928 * Added new argument `mode' to the silc_server_send_new_channel
1929 as it is required in the Channel Payload now.
1931 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1932 and created a new and real SilChannelPayload to represent the
1933 new generic Channel Payload. Implemented the encode/decode
1934 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1936 * Added silc_server_get_client_channel_list to return the list
1937 of channels the client has joined for WHOIS command reply.
1938 Affected file silcd/server.[ch].
1940 * Implemented the channel list sending in the WHOIS command reply
1941 in server and in the client.
1943 Implemented the channel list displaying on the user interface
1944 as well. Affected file silc/client_ops.c.
1946 * Added silc_channel_payload_parse_list to parse list of Channel
1947 Payloads. It returns SilcDList list of SilcChannelPayloads.
1948 Client for example can use this function to parse the list of
1949 channels it receives in the WHOIS command reply. The caller
1950 must free the list by calling silc_channel_payload_list_free.
1951 Affected files lib/silccore/silcchannel.[ch].
1953 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1955 * Added one new argument <user mode> to the WHOIS command reply
1956 to return the mode of the user in SILC. Updated the protocol
1959 Implemented it to the server and client.
1961 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Fixed the mode printing on the user interface on joining.
1964 Affected file silc/client_ops.c.
1966 * Implemented the UMODE command and user modes in general to the
1967 client library and to the user interface.
1969 * Implemented the UMODE command to the server.
1971 * The server now sends UNKNOWN_COMMAND error status if client sends
1972 unknown command. Affected file silcd/command.c.
1974 * All server commands now handle the command identifier the right
1975 way when sending the command reply to the client. The client can
1976 use to identify the command replies with the identifier.
1978 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1980 * Added silc_server_get_client_route to resolve the route to
1981 the client indicated by the client ID. Affected file is
1984 * Added silc_server_relay_packet as general function to relay
1985 packet to arbitrary destination. This deprecates functions
1986 like _send_private_message_key, _relay_notify etc. Affected
1987 file is silcd/packet_send.[ch].
1989 Removed silc_server_send_key_agreement,
1990 silc_server_send_private_message_key and
1991 silc_server_packet_relay_notify functions from the file
1992 silcd/packet_send.[ch].
1996 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1997 server. Affected file silcd/packet_receive.[ch].
1999 * Implemented the KILL command to the client. Implemented the
2000 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2001 Affected files lib/silcclient/command[_reply].c and
2002 lib/silcclient/client_notify.c. Implemented the KILL notify
2003 printing in the user inteface.
2005 * Fixed a lot silc_parse_nick memory leaks from the client
2006 library in the file lib/silcclient/command.c.
2008 * Changed the silc_server_send_notify_on_channels's `sender'
2009 argument from SilcSocketConnection to SilcClientEntry to
2010 check the sender as entry and not as connection object and not
2011 to send to the client provided as argument. The affected file
2012 is silcd/packet_send.[ch].
2014 * The notify packets that are destined directly to the client used
2015 to not to be processed by the server. Now changed that and the
2016 server processes all notify packets. After relaying the packet
2017 to the client the notify packet is processed in the server.
2019 * The silc_server_free_client_data now checks whether there is
2020 pending outgoing traffic for the client and purges the data to
2021 the network before removing the client entry.
2023 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2025 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2026 an client is killed from the SILC Network. Updated the protocol
2029 Added new function silc_server_send_notify_killed to the
2030 silcd/packet_send.[ch].
2032 * Added function silc_server_packet_relay_notify to relay notify
2033 packets that are destined directly to a client. In this case
2034 the server does not process the notify packets but merely relays
2035 it to the client. Affected file silcd/packet_send.[ch].
2037 Added also silc_server_packet_process_relay_notify to check
2038 whereto relay the notify. Affected file is
2039 silcd/packet_receive.[ch].
2041 * Implemented the KILL command to the server.
2045 * Added the backup schema desgined last fall to the protocol
2046 specs for everyone to see. The specification is in the
2047 *-spec-xx.txt draft and the packet type definitions for the
2048 backup routers is in *-pp-xx.txt draft. Thusly, added also
2049 new packet type SILC_PACKET_CELL_ROUTERS.
2051 * A big security problem in the implementation discovered. The
2052 signoff of an client did not cause new channel key generation
2053 which it of course should've done. The channel keys must be
2054 always re-generated when client leaves (or signoffs) the channel.
2055 The silc_server_remove_from_channels funtion now handles
2056 the channel key re-generation.
2058 * Added `sender' argument to the silc_server_send_notify_on_channels
2059 to not to send the client provided as argument. Affected file
2060 silcd/packet_send.[ch].
2062 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Implemented OPER and SILCOPER commands into the server and
2067 * Added silc_auth_verify and silc_auth_verify_data to verify
2068 the authentication directly from the authentication payload.
2069 It supports verifying both passphrase and public key based
2070 authentication. Affected file lib/silccore/silcauth.[ch].
2072 * Added `hash' field to the SilcIDListData structure. It is the
2073 hash negotiated in the SKE protocol. Affected file is
2076 * Slight redesigning of the SilcAuthPayload handling routines.
2077 Do not send SilcPKCS but SilcPublicKey as argument.
2079 * Implemented the public key authentication support to the
2080 serverconfig. The public key is loaded from the provided path
2081 and saved as authentication data to void * pointer. Thus,
2082 changed the unsigned char *auth_data to void *auth_data;
2084 * Fixed SHUTDOWN command to send the reply before the server
2085 is shutdown. :) Affected file silcd/command.c.
2087 * Fixed fatal bug in CONNECT command. The hostname was invalid
2088 memory and server crashed. Affected file silcd/command.c.
2090 * Fixed fatal bug in CLOSE command. The server_entry became
2091 invalid but was referenced later in the command. Affected file
2094 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2096 * Fixed fatal bug in failure packet handling. Server ignored
2097 the failure and thus crashed when it came.
2101 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2104 that the command may be executed only once in (about) 2 seconds.
2105 The old SILC_CF_LAG flag is same but allows command bursts up
2106 to five before limiting.
2108 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2109 server code. Various commands now includes the CF_LAG_STRICT
2110 flag to disallow any kind of miss-use of the command.
2112 * Fixed the silc_buffer_unformat to not to allocate any data
2113 if the length of the data is zero. It used to allocate the
2114 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2116 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2118 * Changed the format of AdminConnection configuration section
2119 in the server. Added username of the admin to the format.
2120 Affected files silcd/serverconfig.[ch].
2122 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2123 to return admin configuration data by host, username and/or
2126 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2128 * Implemented WHOWAS command to the server. Added the functions:
2130 silc_server_command_whowas_parse,
2131 silc_server_command_whowas_send_reply,
2132 silc_server_command_whowas_from_client and
2133 silc_server_command_whowas_from_server
2135 * Added <Client ID> argument to the WHOWAS command reply. Updated
2136 the protocol specs accordingly.
2138 * Implemented WHOWAS command and command_reply to the client
2141 Implemented the WHOWAS printing on the user interface.
2143 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Added new argument to the WHOWAS command reply, the real name.
2146 It is an optional argument. Updated the protocol specs.
2148 * Added SilcIDCacheDestructor callback that is registered when
2149 the SilcIDCache is allocated. The callback is called when
2150 an cache entry in the ID Cache expires, or is purged from the
2151 cache. Added into lib/silccore/idcache.[ch].
2153 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2154 to destruct the client entries when the cache entry expires.
2155 Other ID Cache's in server and in the client library ignores
2158 * If the ID Cache entry's `expire' field is zero then the entry
2159 never expires. Added boolean `expire' argument to the
2160 silc_idcache_add function in the lib/silccore/idcache.[ch].
2161 If it is TRUE the default expiry value is used.
2163 * Added silc_server_free_client_data_timeout that is registered
2164 when client disconnects. By default for 5 minutes we preserve
2165 the client entry for history - for WHOWAS command.
2167 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2169 * Added support to the server to enforce that commands are not
2170 executed more than once in 2 seconds. If server receives
2171 commands from client more frequently, timeout is registered
2172 to process the commands. Affected file silcd/command.c.
2173 Added new function silc_server_command_process_timeout.
2175 * Changed NICK_NOTIFY handling in client library to check that
2176 if the client's nickname was changed, so there is no need to
2177 resolve anything from the server.
2179 * Removed error printing from the WHOIS and IDENTIFY commands.
2180 If error occurs then it is ignored silently in the client library.
2181 The application, however, may map the received error to
2182 human readable error string. The application currently maps
2183 the NO_SUCH_NICKNAME error to string.
2185 * Made the command status message public to the application. Moved
2186 them from lib/silcclient/command_reply.c to
2187 lib/silcclient/command_reply.h. The application can map the
2188 received command status to the string with the
2189 silc_client_command_status_message function.
2191 * Added check to the server to check that client's ID is same
2192 as the Source ID in the packet the client sent. They must
2195 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * Added dist-bzip hook to the Makefile.am to make bzip2
2198 compressed distributions.
2200 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Server now enforces the maximum length for the nickname and
2203 the channel as protocol specification dictates. 128 bytes for
2204 nickname and 256 bytes for channel name.
2206 * Moved the WHOIS printing to the application. The client libary
2207 does not print out the WHOIS information anymore, the application
2208 must do it. Renamed silc_client_command_reply_whois_print to
2209 the silc_client_command_reply_whois_save.
2211 The client's idle time is also sent to the application now, and
2212 the idle is shown on screen.
2214 * Added silc_client_command_reply_identify_save to save the
2215 received IDENTIFY entries.
2217 * Do not check for channel private keys in message sending and
2218 reception if the channel does not have the PRIVKEY mode set.
2219 Affected file lib/silclient/client_channel.c.
2221 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2223 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2224 just surfaced after chaning the JOIN procedure.
2226 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2228 * Added silc_client_get_clients_by_list to get client entries
2229 from Client ID list, that is returned for example by JOIN
2230 and USERS command replies. The application should use this
2231 function for example when JOIN command reply is received to
2232 resolve the clients already on the channel (library does not
2233 do that anymore as USERS command reply is not used in the JOIN
2234 procedure anymore). Affected files lib/silcclient/silcapi.h and
2235 lib/silcclient/idlist.c.
2237 * JOIN command reply and USERS command reply returns now SilcBuffer
2238 pointers instead of unsigned char pointers when returning
2239 the client list and mode list.
2241 * Added <Client ID> argument to the JOIN command reply, mainly
2242 for the server to identify for which client the command was
2243 originally sent. Updated protocol specs accordingly.
2245 * Added SilcDlist private_key pointer to the SilcChannelEntry
2246 in the client to support the channel private keys. Affected
2247 file is lib/silcclient/idlist.h.
2249 * Added SilcChannelPrivateKey argument to the function
2250 silc_client_send_channel_message so that application can choose
2251 to use specific private ke if it wants to. If it is not provided,
2252 the normal channel key is used, unless private keys are set.
2253 In this case the first (key that was added first) is used
2254 as the encryption key.
2256 * Implemented the support for channel private key handling.
2257 Implemented the following functions:
2259 silc_client_add_channel_private_key,
2260 silc_client_del_channel_private_keys,
2261 silc_client_del_channel_private_key,
2262 silc_client_list_channel_private_keys and
2263 silc_client_free_channel_private_keys
2265 Affected file lib/silcclient/client_channel.c.
2267 * Added the support for the private keys in the channel message
2268 sending and encryption and in the message reception and
2269 decryption. Affected funtions are
2270 silc_client_send_channel_message and silc_client_channel_message.
2272 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2274 * Added SKE's key verify callback to the client library's
2275 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2277 * Removed the statement that server (or router) must send USERS
2278 command reply when joining to the channel so that the client
2279 knows who are on the channel. Instead, the client list and
2280 client's mode list is now sent in the JOIN command reply to the
2281 client who joined channel. This is better solution.
2283 * Added function silc_server_get_users_on_channel and function
2284 silc_server_save_users_on_channel to the silcd/server.[ch].
2286 * Removed function silc_server_command_send_users from the
2289 * Do not show topic on the client library anymore. The topic is
2290 sent in the command reply notify to the application and the
2291 application must show the topic now.
2293 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2295 * Added client searching by nickname hash into the IDENTIFY and
2296 WHOIS commands in the server as they were clearly missing from
2297 them. Affected file is silcd/command.c.
2299 * Fixed a bug in private message receiving in the client library.
2300 The remote ID was freed and it wasn't supposed, now it is
2303 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * Minor fix to the channel payload; allocate the data area, as it
2306 needs to be of specific length.
2308 * If the key agreement port is zero then the operating
2309 system will define the bound port. Affected files are
2310 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2312 * Added new function silc_channel_payload_decrypt into the file
2313 lib/silccore/silcchannel.[ch].
2315 * Moved the channel message etc, check from silc_packet_decrypt
2316 to applications. The library calls now a generic
2317 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2318 when the packet is either normal or special. This was done to
2319 allow more wide range of checking that was not allowed when
2320 the code was in library. Now applications can do virtually any
2321 checks to the packet and return to the library the decision how
2322 the packet should be processed. Affected files are
2323 lib/silccore/silcpacket.[ch].
2325 Added silc_server_packet_decrypt_check to the server and
2326 silc_client_packet_decrypt_check to the client library.
2328 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2329 to send with specified source and destination information.
2331 * Channel message delivery between routers was broken after the
2332 channel key distribution was fixed earlier. The channel key
2333 was used be to distributed to other routers as well which is not
2334 allowed by the protocol. Now this is fixed and channel keys
2335 really are cell specific and the channel message delivery between
2336 routers comply with the protocol specification.
2338 * Fixed various commands in server to check also the global list
2339 for the channel entry and not just the local list. The affected
2340 file silcd/command.c.
2342 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2344 * Added assert()s to buffer formatting and unformatting routines
2345 to assert (if --enable-debug) when error occurs. Affected
2346 file: lib/silcutil/silcbuffmt.c.
2348 * Changed to auto-reconnect to check whether the remote host is
2349 router and register the re-connect timeout if it is. It used
2350 to check that whether we are normal server, but router must do
2351 auto-reconnect with another router as well. Affected file
2354 * Removed the [<key len>] option from CMODE command as the cipher
2355 name decides the key length, nowadays. See the defined ciphers
2356 from the protocol specification.
2358 * Added [<hmac>] option to the CMODE command to define the HMAC
2359 for the channel. Added SILC_CMODE_HMAC channel mode.
2361 * Added [<hmac>] option for the JOIN command so that user can
2362 select which HMAC is used to compute the MACs of the channel
2365 * Added Hmac field to the Channel Message Payload. The integrity
2366 of plaintext channel messages are now protected by computing
2367 MAC of the message and attaching the MAC to the payload. The
2368 MAC is encrypted. Now, it is clear that this causes some
2369 overhead to the size of the packet but rationale for this is that
2370 now the receiver can verify whether the channel message decrypted
2371 correctly and also when private keys are set for the channel the
2372 receiver can decrypt the packet with several keys and check from
2373 the MAC which key decrypted the message correctly.
2375 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2376 lib/silccrypt/silccipher.[ch].
2378 * Added silc_hash_len to return the digest length into the
2379 lib/silcrypt/silchash.[ch].
2381 * Rewrote parts of Silc Channel Payload interface in the
2382 lib/silccore/silcchannel.[ch]. The encode function now also
2383 encrypts the packet and parse function decrypts it.
2385 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2387 * Fixed a minor formatting bug in the SKE's key material processing.
2388 It actually might have processed the keys wrong way resulting
2391 * Redefined the mandatory HMAC algorithms and added new algorithms.
2392 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2393 and hmac-md5 truncated to 96 bits. The mandatory is now
2394 hmac-sha1-96. Rest are optional (including the one that used
2395 to be mandatory). Rationale for this is that the truncated HMAC
2396 length is sufficient from security point of view and can actually
2397 make the attack against the HMAC harder. Also, the truncated
2398 HMAC causes less overhead to the packets. See the RFC2104 for
2401 * Added new [hmac] configuration section. The SKE used to use
2402 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2403 is of course wrong. The official names that must be proposed in
2404 the SKE are the ones defined in the protocol specification
2405 (hmac-sha1-96 for example). The user can configure any hmac
2406 using any hash function configured in the [hash] section. At
2407 least, the mandatory must be configured.
2409 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2411 * Added HMAC list to the SKE proposal list. It has now both
2412 hash algorithm list and HMAC list. This makes the protocol
2413 incompatible with previous versions. The SKE now seems to work
2414 the way it is supposed to work, for the first time actually.
2416 * Defined plain Hash algorithms to the protocol specification.
2419 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Implemented support for key agreement packets into the server.
2422 Added functions silc_server_key_agreement and
2423 silc_server_send_key_agreement. Other than these functions,
2424 server has nothing to do with this packet.
2426 * Added support for private message key packets into the server.
2427 Added functions silc_server_private_message_key and
2428 silc_server_send_private_message_key.
2432 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2433 called in the protocol's final callback instead in the END
2434 protocol state. This makes a little more sense and in the same
2435 time in client we can use the same protocol routines for normal
2436 key exchange and to key agreement packet handling as well.
2438 * Added to both client's and server's KE protocol context the
2439 SilcSKEKeyMaterial pointer to save the key material. We will
2440 bring the key material to the protocol's final callback by doing
2441 this. The final callback must free the key material.
2443 * Added SKE's packet_send callback into client's KE protocol
2444 context so that the caller can choose what packet sending function
2445 is used. This way we can use different packet sending when
2446 doing normal SKE when doing key agreement packet handling (in
2447 the key agreement packet handling we do not want to encrypt
2450 * Implemented the responder side of the key agreement routines
2451 in the client. The client can now bind to specified port and
2452 accept incoming key negotiation. The key material is passed
2453 to the application after the protocol is over.
2455 * Implemented the processing of incoming Key Agreement packet
2456 in the client. Added function silc_client_key_agreement to
2459 * Implemented the intiator side of the key agreement routines
2460 in the client. The client can now initiate key agreement with
2461 another remote client. The key material is passed to the
2462 application after the protocol is over.
2464 * Created client_keyagr.c to include all the key agreement
2467 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2468 SILC_TASK_CALLBACK except that it is not static.
2470 * Created client_notify.c and moved the Notify packet handling
2471 from the client.[ch] into that file.
2473 * Created client_prvmsg.c and moved all private message and
2474 private message key routines from the client.[ch] into that file.
2476 * Create client_channel.c and moved all channel message and
2477 channel private key routines from the client.[ch] into that file.
2479 * Changed silc_client_get_client_by_id_resolve to resolve with
2480 WHOIS command instead of IDENTIFY command, in the file
2481 lib/silclient/idlist.c.
2483 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Implemented the SKE's responder side to the Client library.
2487 * When FAILURE is received to the protocol do not trust it
2488 blindly. Register a timeout to wait whether the remote closes
2489 the connection as it should do it, only after that process the
2490 actual failure. This was changed to both client and server.
2492 * Added client_internal.h to include some of the structures
2493 there instead of client.h in lib/silcclient/.
2495 * Added function silc_task_unregister_by_callback to unregister
2496 timeouts by the callback function.
2498 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2500 * Some "Incomplete WHOIS info" errors has been appearing on the
2501 log files. Took away the entry->userinfo check from WHOIS
2502 reply sending. The entry->userinfo is now " " if client did not
2503 provide one. I thought this was fixed earlier but something
2504 is wrong still. Let's see if the error still appears.
2506 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Fixed a minor bug in the login when the channel key is
2509 re-generated in the server. It used to generate the key in
2510 wrong order and thus caused problems in the channel traffic.
2512 * Fixed a minor bug in channel key distsribution after
2513 KICK command. The key was not sent to the router even though
2516 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2518 * Added silc_ske_process_key_material_data as generic routine
2519 to process any key material as the SILC protocol dictates. The
2520 function is used by the actual SKE library but can be used by
2521 applications as well. This relates to the private message keys
2522 and the channel private keys since they must be processed the
2523 same way the normal SILC session keys. The protocol dictates
2524 this. Affected files: lib/silcske/silcske.[ch].
2526 Added also silc_ske_free_key_material to free the
2527 SilcSKEKeyMaterial structure.
2529 * Defined silc_cipher_set_key function to set the key for
2530 cipher without using the object's method function. The affected
2531 files: lib/silccrypt/silccipher.[ch].
2533 * Implemented silc silc_client_add_private_message_key,
2534 silc_client_add_private_message_key_ske,
2535 silc_client_del_private_message_key,
2536 silc_client_list_private_message_keys and
2537 silc_client_free_private_message_keys functions in the
2540 Added functions silc_client_send_private_message_key to send
2541 the Private Message Key payload and silc_client_private_message_key
2542 to handle incoming Private Message Key payload.
2544 * Added Cipher field to the Private Message Key payload to set
2545 the cipher to be used. If ignored, the default cipher defined
2546 in the SILC protocol (aes-256-cbc) is used.
2548 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2550 * Removed lib/silcclient/ops.h file.
2552 Redefined parts of the SILC Client Library API. Created new
2553 file silcapi.h that deprecates the ops.h file and defines the
2554 published Client Library API. Defined also private message key
2555 API and channel private key API into the file.
2557 This is the file that the application must include from the
2558 SILC Client Library. Other files need not be included by
2559 the application anymore.
2561 * Added new key_agreement client operation callback and also
2562 defined the Key Agreement library API for the application.
2564 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2566 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2567 is used by clients to request key negotiation between another
2568 client in the SILC network. If the negotiation is started it
2569 is performed using the SKE protocol. The result of the
2570 negotiation, the secret key material, can be used for example
2571 as private message key.
2573 Implemented the Key Agreement payload into the files
2574 lib/silccore/silauth.[ch].
2576 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2578 * Redefined ciphers for the SILC protocol. Added some new ciphers
2579 and defined the key lengths for the algorithms. Changed the
2580 code accordingly. The default key length is now 256 bits.
2582 * Fixed SKE key distribution function silc_ske_process_key_material
2583 when the key length is more than 128 bits. The default key
2584 length in SILC is now 256 bits.
2586 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2587 to indicate unsupported algorithm.
2589 * Renamed rijndael.c to aes.c and all functions as well.
2591 * Fixed a long standing channel key setting bug in client library.
2592 Weird that it has never surfaced before.
2594 * Fixed bug in channel deletion. If the entire channel is removed
2595 then it must also delete the references of the channel entry
2596 from the client's channel list as the client's channel entry and
2597 the channel's client entry share same memory.
2599 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2601 * Implemented CONNECT and SHUTDOWN commands in the client.
2603 * Implemented CLOSE command to the client.
2605 * Added the function silc_idlist_find_server_by_name into the
2606 files silcd/idlist.[ch].
2608 Added the function silc_idlist_find_server_by_conn into the
2609 files silcd/idlist.[ch].
2611 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2613 * DIE command was renamed to SHUTDOWN. Updated the both code
2616 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2617 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2619 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2622 * Added function silc_server_create_connection function to create
2623 connection to remote router. My server implementation actually
2624 does not allow router to connect to normal server (it expects
2625 that normal server always initiates the connection to the router)
2626 so the CONNECT command is only good for connecting to another
2629 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2632 or some other client was kicked from the channel.
2634 Implemented the handling of the notify type to both client
2637 Implemented silc_server_send_notify_kicked to send the KICKED
2638 notify. It is used to send it to the server's primary router.
2640 * Implemented the KICK command into server and client.
2642 * Added `query' argument to the silc_idlist_get_client function
2643 to indicate whether to query the client from server or not if
2646 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2647 to indicate that the client is not channel founder.
2651 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2653 * Removed the rng context from SilcPacketContext structure and
2654 changed that the packet routine uses the Global RNG API.
2656 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Added support for quit message that client can "leave" on the
2659 channel when it quits the SILC. It is ditributed inside the
2660 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2662 Added silc_server_free_client_data that will take the
2663 signoff message as argument.
2665 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2667 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Updated parts of the protocol specification to keep it up
2672 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2674 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2675 payloads in one packet.
2677 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2678 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2679 use now the new List flag.
2681 * Also deprecated the following packet types: REPLACE_ID,
2682 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2684 * Added list support for Notify packet in server.
2686 * Added silc_server_send_notify_channel_change to send the
2687 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2688 the silc_server_send_replace_id.
2690 * Added silc_server_send_notify_nick_change to send the
2691 NICK_CHANGE notify type. Deprecates the function
2692 silc_server_send_replace_id.
2694 * Added silc_server_send_notify_join to send the JOIN notify type.
2695 Deprecates the function silc_server_send_new_channel_user.
2697 * Added silc_server_send_notify_leave to send LEAVE notify type.
2698 Deprecates the function silc_server_send_remove_channel_user.
2700 * Added silc_server_send_notify_cmode and
2701 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2702 types. Deprecates the silc_server_send_set_mode function.
2704 * Added SERVER_SIGNOFF notify type to indicate that server has
2705 quit. This means that all clients on the channel from that
2706 server will drop. This can be also used when netsplit happens.
2708 Deprecated REMOVE_ID packet type since it is not needed anymore
2711 Added silc_server_send_notify_server_signoff to send the
2712 SERVER_SIGNOFF notify type. Deprecates the function
2713 silc_server_send_remove_id.
2715 Added also silc_server_send_notify_signoff to send the
2716 SIGNOFF notify type.
2718 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2719 SILC protocol from this day on. Changed the protocol
2720 specification as well.
2722 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2723 notify type. It is used between routers to notify about
2724 topic changes on a channel.
2726 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2729 * Partly updated the protocol specification to comply with the
2730 changes now made. It is still though a bit outdated.
2732 * The JOIN notify type now takes one extra argument <Channel ID>.
2733 The packet used to be destined to the channel but now the
2734 JOIN type may be sent as list thus it is impossible to
2735 destine it to any specific channel. By adding this argument
2736 it is again possible.
2738 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2740 * Added CREDITS file. The CHANGES and CREDITS file will appear
2741 in the distribution as well.
2743 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2746 types in the server's silcd/packet_receive.c.
2748 * Implemented CMODE and CUMODE to work in router environment.
2750 * Fixed minor encoding and decoding buglet from the
2751 lib/silccore/silcmode.c.
2753 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2756 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2758 * Changed all SilcConfigServer* and silc_config_server* to
2759 SilcServerConfig* and silc_server_config*, respectively.
2762 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2764 * Associated the ID (client or server ID) to the Authentication
2765 Payload to avoid any possibility of forging. Updated the
2766 protocol specification and the code accordingly.
2768 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * The RSA key length is now save to the RsaKey context in the
2771 key generation process in lib/silccrypt/rsa.c. The key length
2772 is now used to figure out the maximum size of the block allowed
2773 to be encrypted/signed.
2775 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2776 is equivalent to the silc_mp_mp2bin but does not allocate any
2779 * Changed silc_mp_mp2bin API to take length argument. If it is
2780 non-zero then the buffer is allocated that large. If zero, then
2781 the size is approximated using silc_mp_sizeinbase, which however
2784 * Created Global RNG API which is global RNG that application can
2785 initialize. After initializing, any routine anywhere in the
2786 code (including library) can use RNG without allocating a new
2787 RNG object. This was done to allow this sort of use of the
2788 RNG in code that has no chance to allocate RNG object. All
2789 applications currently allocate this and many routines in the
2790 library use this. Affected file lib/silccrypt/silcrng.[ch].
2792 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2793 it to use the Global RNG API.
2795 * Defined Authentication Payload into protocol specification that
2796 is used during SILC session to authenticate entities. It is
2797 used for example by client to authenticate itself to the server
2798 to obtain server operator privileges.
2800 Implemented this payload into the lib/silccore/silcauth.[ch].
2801 Implemented also routines for public key based authentication
2802 as the new protocol specification dictates.
2804 Moved definitions of different authentication methods from
2805 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2807 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2808 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2809 silc_pkcs_verify_with_hash functions into the file
2810 lib/silccrypt/silcpkcs.[ch].
2812 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * The client entry's userinfo pointer must be always valid.
2815 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2816 will fail since it requires the userinfo. Now, the userinfo
2817 is allocated as "" if actual userinfo does not exist. Actually,
2818 it must exist and it is totally Ok to drop client connections
2819 that does not announce the userinfo. However, we will make
2820 this workaround for now.
2822 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2823 to return the remote port by socket.
2825 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2827 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2828 SILC_SERVER_PENDING_EXEC and added an new macro
2829 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2830 data or when error occurs while processing the pending command.
2832 Added new argument `destructor' into silc_server_command_pending
2833 and to the SilcServerCommandPending object. This destructor is
2834 now called after calling the pending callback or if error occurs
2835 immediately. If error occurs the actual pending callback won't
2836 be called at all - only the destructor. The destructor may be
2837 NULL if destructor is not needed.
2839 All this applies for client library code as well. Similar
2840 changes were made there as well for the pending commands.
2842 In the client, the application must now allocate the
2843 SilcClientCommandContext with the silc_client_command_alloc
2846 * Added reference counter to the SilcServerCommandContext. Added
2847 function silc_server_command_alloc and silc_server_command_dup
2850 Same type of functions added to the client library for the same
2853 * Removed the cmd_ident from IDListData away since it is now
2854 global for all connections. It is the command identifier used
2855 in command sending and with pending commands. The affected file
2858 * Added reference counter to the SilcSocketConnection objecet to
2859 indicate the usage count of the object. The object won't be
2860 freed untill the reference counter hits zero. Currently only
2861 server uses this, and client ignores it. The client must be
2862 set to use this too later. The affected files are
2863 lib/silccore/silcsockconn.[ch]. Added also the function
2864 silc_socket_dup to increase the reference counter.
2866 This was mainly added because it is possible that the socket
2867 is removed underneath of pending command or other async
2868 operation. Now it won't be free'd and proper DISCONNECTING
2869 flags, etc. can be set to avoid sending data to connection that
2870 is not valid anymore.
2872 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2873 the connection. After that it sets SILC_SET_DISCONNECTED.
2874 It is, however, possible that the socket data is not still freed.
2875 The silc_server_packet_process now checks that data is not
2876 read or written to connection that is DISCONNECTED. The socket
2877 get's freed when the reference counter hits zero.
2879 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * Changed the client operation API: channel_message operation's
2882 `sender' is now the client entry of the sender, not the nickname
2883 and the `channel' is the channel entry, not the channel name.
2885 In the private_message operation the `sender' is now also the
2886 client entry of the sender not the nickname.
2888 Affected file is lib/silcclient/ops.h and all applications
2889 using the client operations.
2891 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Moved the calling of ops->connect() from connect_to_server_final
2894 into receive_new_id functin since that is the point when the
2895 client is actually allowed to send traffic to network. The
2896 affected file is lib/silcclient/client.c.
2898 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2900 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2901 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2902 (if needs broadcasting) instead of broadcasting the packets one
2903 by one which would make a burst in the network traffic.
2905 * Added `broadcast' argument to the functions in silcd/server.[ch]
2906 silc_server_create_new_channel[_with_id] to indicate whether
2907 to send New Channel packet to primary router.
2909 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Added new function into the silcd/server.[ch] files:
2912 silc_server_create_new_channel_with_id to create new channel with
2913 already existing Channel ID.
2915 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2916 lib/silccore/silcpacket.h. This packet is used t send list of
2917 Set Mode payloads inside one packet. Server uses this to set
2918 the modes for the channels and clients on those channels, that it
2919 announced to the router when it connected to it. The protocol
2920 specification has been updated accordingly.
2922 * The silc_server_new_channel did not handle the packet coming
2923 from normal server as it normally does not send that. However,
2924 when it announces its channels it does send it. Implemented
2925 the support for that.
2927 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2928 into the file lib/silccore/id.h.
2930 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Fixed memory leaks in the functions silc_idlist_del_client,
2933 silc_idlist_del_channel and silc_idlist_del_server in the file
2934 silcd/idlist.c. All of those leaked like a sieve.
2936 * Fixed some small memory leaks in the client's function
2937 silc_client_notify_by_server.
2939 * Added functions into silcd/server.c: silc_server_announce_clients,
2940 silc_server_announce_channels and silc_server_announce_server.
2941 These functions are used by normal and router server to announce
2942 to its primary router about clients, channels and servers (when
2943 router) that we own. This is done after we've connected to the
2946 These functions effectively implements the following packet types:
2947 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2948 and SILC_PACKET_NEW_ID_LIST.
2950 * Added new functions into the silcd/packet_receive.[ch]:
2951 silc_server_new_id_list, silc_server_new_channel_list and
2952 silc_server_new_channel_user_list to handle the incoming
2953 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2955 * Added support of changing Channel ID in the function
2956 silc_server_replace_id. If the server that announces a channel
2957 to the router already exists in the router (with same name but
2958 with different Channel ID), router is responsible to send
2959 Replace ID packet to the server and force the server to change
2960 the Channel ID to the one router has.
2962 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2963 client that the Channel ID has been changed by the router. The
2964 normal server sends this to the client. Client must start using
2965 the new Channel ID as the channel's ID.
2967 Implemented handling of this new type into lib/silcclient/client.c
2968 into the function silc_client_notify_by_server.
2970 * Added new function silc_idlist_replace_channel_id into the files
2971 silcd/idlist.[ch] to replace the Channel ID.
2973 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Call silc_server_command_identify_check always when processing
2976 the IDENTIFY command in silcd/command.c
2978 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2981 send keepalive packets. The packet can be sent by clients,
2982 servers and routers.
2984 Added function silc_socket_set_heartbeat into the file
2985 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2986 If not set, the heartbeat is not performed. The actual
2987 heartbeat is implemented in the low level socket connection
2988 library. However, application is responsible of actually
2991 Added silc_server_send_heartbeat to send the actual heartbeat
2992 packet into silcd/packet_send.[ch]. Server now performs
2993 keepalive with all connections.
2995 * Added silc_task_get_first function into lib/silcutil/silctask.c
2996 to return the timeout task with shortest timeout. There was a bug
2997 in task unregistration that caused problems. TODO has been
2998 updated to include that task system must be rewritten.
3000 * The client library will now resolve the client information when
3001 receiving JOIN notify from server for client that we know but
3002 have incomplete information.
3004 * Rewrote parts of silc_server_remove_from_channels and
3005 silc_server_remove_from_one_channel as they did not remove the
3006 channel in some circumstances even though they should've.
3008 * Encryption problem encountered in server:
3010 The LEAVE command used to send the Channel Key packet to the
3011 router immediately after generating it. However, the code
3012 had earlier sent Remove Channel user packet but not immediately,
3013 ie. it was put to queue. The order of packets in the router
3014 was that Channel Key packet was first and Remove Channel User
3015 packet was second, even though they were encrypted in the
3016 reverse order. For this reason, MAC check failed. Now, this
3017 is fixed by not sending the Channel Key packet immediately but
3018 putting it to queue. However, this is more fundamental problem:
3019 packets that are in queue should actually not be encrypted
3020 because packets that are sent immediately gets encrypted
3021 actually with wrong IV (and thus MAC check fails). So, packets
3022 that are in queue should be encrypted when they are sent to
3023 the wire and not when they put to the queue.
3025 However, the problem is that the current system has not been
3026 designed to work that way. Instead, the packet is encrypted
3027 as soon as possible and left to the queue. The queue is then
3028 just purged into wire. There won't be any fixes for this
3029 any time soon. So, the current semantic for packet sending
3032 o If you send packet to remote host and do not force the send
3033 (the packet will be in queue) then all subsequent packets to the
3034 same remote host must also be put to the queue. Only after the
3035 queue has been purged is it safe again to force the packet
3038 o If you send all packets immediately then it safe to send
3039 any of subsequent packets through the queue, however, after
3040 the first packet is put to queue then any subsequent packets
3041 must also be put to the queue.
3043 Follow these rules and everything works fine.
3045 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3047 * Added new function silc_server_remove_clients_by_server to
3048 remove all client entries from ID list when the server connection
3049 is lost. In this case it is also important to invalidate all
3050 client entires as they hold the invalid server entry. This
3051 fixes fatal bug when server has lost connection and will reconnect
3054 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3056 * Made some sanity checks to silc_server_daemonise like to check
3057 whether the requested user and group actually exists.
3059 * Added sanity check to SKE's silc_ske_responder_finish to check
3060 that the public and private key actually is valid.
3062 * Invalidate the client's nickname when receiving Replace ID
3063 packet and the Client ID is being replaced. This means that the
3064 server will query the nickname if someone needs it (client)
3067 * Sort the ID Cache in client library when the ID Cache data
3068 has changed (needs sorting).
3070 * Do not allow for SILC client to create several connections to
3071 several servers. The client does not support windows right now
3072 and generating multiple connections causes weird behaviour.
3074 Irssi-silc client does support windows and can handle several
3075 connections without problems, see: www.irssi.org and SILC plugin.
3077 * Fixed some places where client was added to the IDList. The
3078 rule of thumb is following (in order to get everything right):
3079 If the client is directly connected local client then the
3080 `connection' argument must be set and `router' argument must be
3081 NULL to silc_idlist_add_client function. If the client is not
3082 directly connected client then the `router' argument must
3083 bet set and the `connection' argument must be NULL to the
3084 silc_idlist_add_client function.
3086 * The funtion silc_server_packet_send_local_channel actually did
3087 not check whether the client was locally connected or not. It
3088 does that now. Fixed a bug related to LEAVE command.
3090 * Fixed Remove Channel User payload parsing bug in server's
3091 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3093 * The server's silc_server_save_channel_key now checks also the
3094 global ID list for the channel as it might not be in the local
3095 list. Fixed a bug related to LEAVE command.
3097 * Is this the end of the [<unknown>] buglet that has been lurking
3098 around for a long time? A little for loop fix in server's
3099 silc_server_command_whois_parse that is used by both IDENTIFY
3100 and WHOIS command. At least, this was a clear bug and a cause
3101 of one type of [<unknown>] buglet.
3103 * WHOIS and IDENTIFY commands call the function
3104 silc_server_command_[whois/identify]_check function even if
3105 we are not router server.
3107 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3109 * Added --with-gmp configuration option. If set the GMP
3110 is always compiled in the SILC source tree. If not set then
3111 it is checked whether the system has the GMP3 installed. If
3112 it has then the GMP won't be compiled (the system's headers
3113 and library is used), if it doesn't have it then the GMP is
3114 compiled in the SILC source tree.
3116 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Changed RSA private exponent generation to what PKCS #1
3119 suggests. We try to find the smallest possible d by doing
3120 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3121 not security fix but optimization.
3123 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3125 * Added new config entry [Identity] to fork the server and run
3126 it as specific user and group. A patch from Bostik.
3128 * Imported Dotconf configuration library into lib/dotconf.
3129 This will be used to create the SILC configuration files later.
3130 It will appear in the distsribution after this commit.
3132 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * A big code auditing weekend happening. Auditing code for
3135 obvious mistakes, bugs and errors. Also, removing any code
3138 Removed files for being obsolete:
3140 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3141 inline in the file lib/silcutil/silcbuffer.h)
3143 o lib/silcutil/silcbufutil.c (the header has inline versions)
3145 Changed code to fix possible error conditions:
3147 o The buffer formatting routines now check that the destination
3148 buffer really has enough space to add the data. This applies for
3149 both buffer formatting and unformatting
3150 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3151 unformatting was changed to accomodate following rules:
3152 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3153 sent to the function while XXX_*STRING will not allocate or copy
3154 the data into the buffer. Instead it sets the pointer from the
3155 buffer into the pointer sent as argument (XXX_*STRING used to
3156 require that the pointer must be allocated already). This change
3157 makes this whole thing a bit more consistent and more optimized
3158 (note that the data returned in the unformatting with XXX_*STRING
3159 must not be freed now). The routines return now -1 on error.
3161 o Tried to find all code that use buffer_format and buffer_unformat
3162 and added return value checking to prevent formatting and
3163 especially unformatting errors and possible subsequent fatal
3166 o Changed ske->x and ske->KEY to mallocated pointers in
3167 lib/silcske/silcske.h. Fixed possible data and memory leak.
3169 o Added return value checking to all *_parse* functions. Fixed
3170 many memory leaks as well.
3172 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3173 so that buffer overflows would not happen. All code now also
3174 checks the return value as it can fail.
3176 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * Added reconnection support to server if the normal server looses
3179 its connection to the router (for example if router is rebooted).
3180 The server performs normal reconnection strategy implemented
3181 to the server. Affected file silcd/server.c.
3183 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3185 * Added new packet type SILC_PACKET_SET_MODE that is used to
3186 distribute the information about changed modes (for clients,
3187 channels and clients channel modes) to all routers in the
3188 network. Updated the protocol specification accordingly.
3190 Added functions into silcd/packet_send.c and
3191 silcd/packet_receive.c: silc_server_send_set_mode,
3192 silc_server_set_mode.
3194 Added new files silcmode.[ch] into lib/silccore that implements
3195 the encoding and decoding of Set Mode Payload. Added new type
3196 SilcSetModePayload. Moved the definitions of different modes
3197 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3199 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * Oops, a little mistake in server's connection authentication
3202 protocol. The protocol is not ended with FAILURE but with
3203 SUCCESS if the authentication is Ok. :) Affected file is
3206 * Implemented NICK_CHANGE notify handling in server in the file
3207 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3208 the local clients on the channel. After the changing nickname
3209 in router environment snhould work and the [<unknown>] nickname
3210 should appear no more.
3212 The silc_server_replace_id function that receives the Replace ID
3213 payload now sends the NICK_CHANGE notify type also in the file
3214 silcd/packet_receive.c
3216 * Changed WHOIS and IDENTIFY command to support the maximum amount
3217 of arguments defined in protocol specs (3328 arguments). This
3218 fixed a bug that caused problems when there were more than three
3221 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3223 * Added extra parameter, command identifier, to the
3224 silc_client_send_command so that explicit command identifier
3227 Changed that ID list routines uses specific command identifier
3228 when sending WHOIS/IDENTIFY requests to the server so that they
3229 can be identified when the reply comes back.
3231 Affected files lib/silcclient/command.[ch],
3232 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3234 * Added `sender' argument to silc_server_packet_send_to_channel
3235 to indicaet the sender who originally sent the packet to us
3236 that we are now re-sending. Ignored if NULL. Affected file
3237 silcd/packet_send.[ch].
3239 * Added some server statistics support in silcd/server_internal.h
3240 SilcServerStatistics structure and around the server code. Also
3241 send some nice statistics information when client is connecting
3244 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Fixed channel ID decoding in server's JOIN command reply in
3247 silcd/command_reply.c
3249 * Fixed braodcasting of replace ID payload to not to send it if
3250 we are standalone server in silcd/packet_receive.c.
3252 * Fixed all channel message sending routines to not to send
3253 packets to clients that has router set, since they are routed
3254 separately in the same function earlier. Affects file
3255 silcd/packet_send.c and all channel packet sending functions.
3257 * In USERS reply, res_argv[i] are not allocated, the table
3258 is allocated. Thus changed that free the table, not its
3261 * In server's whois_check and identify_check if the client is
3262 locally connected do not send any WHOIS commands - they are not
3265 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Fixed some minor bugs in client when sending WHOIS command. The
3268 arguments was in wrong order.
3270 * Removed statis function add_to_channel from server in
3271 silcd/command.c that was previously used with the joining but
3274 * Tested USERS command in router environment successfully with two
3275 routers, two servers and two clients.
3277 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Reorganized the USERS command and command reply in client library
3280 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3281 When the command is given by user we register a pending command
3282 callback that will reprocess the command after the reply has been
3283 received from the server. When reprocessing the packet we then
3284 display the information. Thus, the USERS information is displayed
3285 now in the command callback instead of in the command reply
3286 callback. The processing of the command is same as previously
3287 when server has sent the command reply in the JOINing process.
3289 * Added to USERS command in silcd/command_reply.c to join the client,
3290 we didn't use to know about, to the channel after we've created
3291 a client entry for it. Also, for clienet we did know already still
3292 check whether it is on the channel or not and add it if not.
3294 * Removed silc_server_command_join_notify as the function and its
3297 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Changed the client's pending command handling to the same as the
3300 server's pending command handling. It is also now possible to
3301 execute command reply functions from other command reply
3302 function as the function callbacks for commands and command
3303 replies are one and same. The pending commands are not static
3304 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3305 in client connection context. Thus, pending commands are server
3306 connection specific as it is convenient.
3308 Changed the function silc_client_command_pending and
3309 silc_client_command_pending_del and added new function
3310 silc_client_command_pending_check. Removed the
3311 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3314 * Added cmd_ident, current command identifier, to the client
3315 connection context in lib/silcclient/client.h to keep track on
3316 command identifiers used in command sending. Client's command reply
3317 function handling now supports the mandatory command identifiers.
3319 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3320 funtions in client to fully support pending command callbacks.
3322 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3323 as one of the arguments to the application in the command reply
3326 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3327 before first releasing SILC but came back. Now it is removed again
3328 and should come back nomore. The FORWARDED flag was used only
3329 by the JOINing procedure by forwarding the command packet to router.
3330 Now, the JOINing procedure has been changed to more generic (due
3331 to various router environment issues) and FORWARDED is not needed
3332 anymore for anything. The protocol specification is yet to be
3335 Now, removed silc_server_packet_forward from server and the flag
3336 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3338 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Renamed NAMES command to USERS command. The NAMES was named that
3341 due to historical reasons. Now it is renamed. Also, rewrote
3342 parts of the USERS command. The nickname list is not sent anymore
3343 by the server. Only Client ID and mode lists are sent in the USERS
3344 command. Changed this also to the protocol specification.
3346 The client now resolves the names and stuff after it receives
3347 the USERS list from the server when joining to the channel.
3349 * WHOIS and IDENTIFY commands has been changed to support multiple
3350 Client ID's per command. One can now search for multiple users
3351 in the network by sending only one WHOIS or IDENTIFY command.
3352 Changed the code and the protocol specifications.
3354 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3355 uses silc_server_command_whois_parse to parse the request. */
3357 * If normal server, do not parse the WHOIS and IDENTIFY requests
3358 before sending it to the router. Saves some time.
3360 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Fixed JOIN command on client library. Wrong number of arguments
3363 used to crash the client.
3365 * Added silc_server_channel_has_global function to check whether
3366 channel has global users or not.
3368 * Added silc_server_channel_has_local function to check whether channel
3369 has locally connected clients on the channel.
3371 * The silc_server_remove_from_one_channel now checks whether the
3372 channel has global users or not after given client was removed from
3373 the channel. It also checks whether the channel has local clients
3374 on the channel anymore. If it does not have then the channel entry
3375 is removed as it is not needed anymore.
3377 * The silc_server_notify now checks on JOIN notify whether the joining
3378 client is one of locally connected or global. If it is global then
3379 the channel has now global users on the channel and that is marked
3380 to the channel entry. Also, it now saves the global client to
3381 global list who is joining and JOINs it to the channel. This is
3382 for normal server, that is.
3384 Changed silc_server_send_notify_on_channel,
3385 silc_server_packet_relay_to_channel and
3386 silc_server_packet_send_to_channel check if we are normal server
3387 and client has router set (ie. global client) do not send the
3388 message to that client, as it is already routed to our router.
3390 * Implemented LEAVE notify type handling in silc_server_notify
3393 * Tested LEAVE command in router environment successfully. Tested
3394 with two routers, two servers and two clients.
3398 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3400 * Implemented SIGNOFF notify type handling in silc_server_notify
3403 * silc_server_remove_id now removes the client entry from all channels
3404 it has joined and thusly sends SIGNOFF notify type.
3406 * Rewrote the NAMES list generation in server by removing two excess
3407 loops. The lists are created now inside one loop.
3409 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * silc_server_remove_channel_user checks now also global list
3412 for channel and client.
3414 * silc_server_new_channel_user checks now both local and global
3415 list for channel and client. Fixed a bug in client id decoding.
3416 Used to decode wrong buffer.
3418 * silc_server_channel_message checks now both local and global
3419 list for channel entry.
3421 * Tested channel joining (hence JOIN) in router environment
3422 successfully. Tested with two routers, two servers and two
3425 * Tested channel message sending in router environment successfully.
3427 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Added silc_server_save_channel_key into server.[ch] to save the
3430 received channel key in Channel Key payload processing. It is
3431 also used in JOIN command reply handling.
3433 Equivalent function silc_client_save_channel_key added into
3434 client.[ch] into client library.
3436 * Changed JOIN command reply to send information whether the channel
3437 was created or not (is existing already) and the channel key
3438 payload. Changed protocol specs accordingly.
3440 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3441 the request was sent by ID and not by nickname. Crashed on
3444 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3447 now correctly save the received data.
3449 * silc_server_free_sock_user_data now notifies routers in the
3450 network about entities leaving the network.
3452 At the same time implemented functions silc_server_remove_id
3453 and silc_server_send_remove_id to receive and send REMOVE_ID
3454 packets. The packet is used to notify routers in the network
3455 about leaving entities. The ID removed will become invalid in
3458 * Added function silc_idlist_del_server into server. Removes and
3459 free's server entry from ID list.
3461 * silc_server_private_message function now checks, if we are router,
3462 that the destination ID really is valid ID, naturally.
3464 * In router when NEW_ID packet is received (for new client) the
3465 hash of the Client ID is saved in the ID Cache but the
3466 client->nickname is set to NULL, instead of putting the hash
3469 IDENTIFY command now also checks that client->nickname must be
3470 valid. If it is not if will request the data from the server who
3471 owns the client. Added new function
3472 silc_server_command_identify_check.
3474 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3475 to set the command to already allocated Command Payload.
3477 * Tested private message sending in router environment with two
3478 routers, two servers and two clients. Fixed minor bugs and now
3481 * Fixed segfault from client's NAMES command. Used to crash if
3484 * Forwarded packets must not be routed even if it is not destined
3485 to the receiver. Changed server code comply with this.
3487 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Added `require_reverse_mapping' boolean value to ServerParams
3490 structure. If TRUE (not default) the server will require that
3491 the connecting host has fully qualified domain name.
3493 If the reverse mapping is not required and hostname could not be
3494 found the IP address is used as hostname.
3496 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3498 * Implemented version string checking to both client and server.
3499 The check is incomplete currently due to the abnormal version
3500 strings used in development version of SILC.
3502 * Changed all command functions in server to use the new
3505 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3507 * Changed char *data to unsigned char *data in ID Cache system to
3508 support binary data as ID Cache data. Changed code to support
3509 binary data in lib/silccore/idcache.c.
3511 * Renamed silc_server_packet_relay_command_reply to
3512 silc_server_command_reply as it is normal packet receiving
3513 function. Rewrote the function to accept command replys for
3514 servers and not only for clients.
3516 * Mark remote router always as registered server if we are connecting
3517 to it. Otherwise, commands sent by the router to us are ignored.
3519 * All ID List find routines now returns the ID Cache Entry pointer
3520 as well if requested.
3522 * WHOIS command works now in router environment, tested with two
3523 routers, two servers and two clients.
3525 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3526 in router environment (as it is almost equivalent to WHOIS) but
3527 hasn't been tested thoroughly. Added new functions:
3529 silc_server_command_identify_parse
3530 silc_server_command_identify_send_reply
3531 silc_server_command_identify_from_client
3532 silc_server_command_identify_from_server
3534 * Disabled route cache adding because adding two different ID's with
3535 same IP replaces the old cache entry thus giving wrong route.
3536 The entry->router->connection is always the fastest route anyway
3537 so route cache may not be needed. Of course, new routes maybe
3538 established after receiving the ID when the entry->router->connection
3539 might not be anymore the most optimal.
3541 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Add route cache for received ID for fast routing.
3545 * Added silc_server_packet_route to route received packet on router
3546 that is not destined to us.
3548 * Renamed silc_server_get_route to silc_server_route_get.
3550 * Added id_string and id_string_len fields into SilcServer to
3551 include encoded ServerID for fast comparing without excess
3552 encoding of the ID's.
3554 * Cleaned up WHOIS command on server side. Added following static
3557 silc_server_command_whois_parse
3558 silc_server_command_whois_check
3559 silc_server_command_whois_send_reply
3560 silc_server_command_whois_from_client
3561 silc_server_command_whois_from_server
3563 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3564 arguments in command replies. All command functions should be
3565 updated to use this macro.
3567 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Minor typo fixes on command reply handling on server.
3571 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3573 * Added silc_server_command_add_to_channel internal routine to add
3574 the client to the channel after router has created the channel and
3575 sent command reply to the server.
3577 * Added generic silc_server_send_command to send any command from
3580 * Use static buffer with ID rendering instead of duplicating data.
3582 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Fixed a channel user mode bug when joining to a channel server gave
3585 everybody channel founder rights, oops.
3587 * We mark ourselves as the router of the incoming server connection
3588 if we are router ourselves. This way we can check in some packet
3589 sending functions whether it is locally connected server. For
3590 incoming router connections we put NULL.
3592 * For router sending packets locally means now always sending the
3593 packet cell wide; to local clients and local servers. For normal
3594 server sending packet locally means sending it to only local
3597 * Fixed the JOIN command to really work in router environment. If the
3598 channel is created it is always created by the router. Router is
3599 also responsible of making the initial joining to the channel,
3600 sending JOIN notify to the sending server and distributing
3601 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3602 does not exist server doesn't do anything else but forward the
3603 command to the router which performs everything.
3605 * Added silc_server_send_channel_key function to send the Channel Key
3608 * Added silc_server_create_channel_key to create new channel key. The
3609 channel key is now re-generated everytime someone joins or leaves
3610 a channel, as protocol dictates. Note: channel->key_len is the
3613 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3616 packet_receive.[ch] to separate packet sending and receiving
3617 routines. The server.[ch] now includes everything else including
3618 actual packet processing (writing and reading data) and other
3621 Renamed silc_server_private_message_send_internal to
3622 silc_server_send_private_message. The routine is still though
3623 used only to relay private messages as server does not send
3624 private messages itself.
3626 Renamed silc_server_new_channel to silc_server_create_new_channel
3627 and added new function sicl_server_new_channel that handles the
3628 incoming New Channel packet. Added also new sending function
3629 silc_server_send_new_channel to send New Channel Payload.
3631 * Added new function silc_server_notify to process incoming notify
3632 packet to the server/router. Server may then relay the notify
3633 to clients if needed.
3635 * Added new function silc_server_new_channel_user to process incoming
3636 New Channel User packet. Router will redistribute the packet and
3637 send JOIN notify to its local clients and locally connected servers
3638 if needed. Normal server will send JOIN notify to its local client
3639 on same channel when received this packet. Added also corresponding
3640 sending function silc_server_send_new_channel_user to sent the
3643 * Added boolean route argument to send_notif_to_channel and
3644 packet_send_to_channel functions to attempt to route the packet
3645 if it is TRUE and send only locally if it is FALSE.
3647 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3649 * silc_server_replace_id now broadcasts the received replace ID
3650 packet if it is not broadcast packet already. The router must
3651 broadcast to inform other routers about changed ID.
3653 * Added backpointer to server's router into SilcServer context in
3654 silcd/server_internal.h.
3656 * Fixed silc_server_packet_broadcast to send correct broadcast
3659 * The channel key is now distributed to the local client as soon
3660 as it is received from the router (in router environment) so that
3661 no other packet may be sent for the channel until client has
3664 * silc_server_remove_channel_user now broadcasts the received
3665 Remove Channel User packet if it is not broadcast packet already.
3666 The router must broadcast to inform other routers about removed
3669 * Added users field into SilcPacketContext that is a reference count
3670 of the context. One can increase the reference count by calling
3671 silc_packet_context_dup which is now changed to just increase the
3672 reference count instead of duplicating the data. The reference
3673 count is decresed by calling silc_packet_context_free that will
3674 free the data after the reference count hits zero.
3676 For now on the packet context and everything allocated into it
3677 (including the raw packet from network) must be freed by calling
3678 the new silc_packet_context_free function. Added also new function
3679 silc_packet_context_alloc that must be used now to allocate the
3680 context. This also means that if a routine is asynchronous from
3681 silc_[client/server]_packet_parse_type the packet context must
3682 be duplicated by calling silc_packet_context_dup. Otherwise it
3683 gets free'd after silc_[client/server]_packet_parse_type returns.
3684 Also, one must remember that if packet is duplicated then its
3685 reference count must be decresed by calling the free function as
3686 many times as it was duplicated.
3688 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3689 from both client and server.
3691 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3693 * Made joining to a channel working in router environment.
3695 * Cleaned up JOIN command on server side and create function
3696 silc_server_command_join_channel internal routine to make the
3699 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3701 * Changed silc_command_pending list to SilcDList. Also, added
3702 `ident' field to SilcServerCommandPending structure to identify
3703 the reply and to call correct callback.
3705 Added silc_server_command_pending_check function to replace the
3706 corresnponding macro. The silc_command_pending list is not
3709 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3710 to set identifier to previously allocated Command Payload. It
3711 is used to set identifier for command when resending Command
3714 * Added silc_command_payload_encode_payload to encode Command
3715 Payload buffer from SilcCommandPayload structure.
3717 * Added silc_argument_payload_encode_payload to encode Argument
3718 payload buffer from SilcArgumentPayload structure.
3720 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Changed WHOIS command to support router connection on server side.
3723 The whois request is always sent to router unless the server is
3724 standalone server. After server has received the reply from the
3725 router will it send the reply to the client.
3727 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3728 broadcast received broadcast packet. The function is used only
3729 by router. The broadcast packet is always sent to the router's
3732 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3733 render given ID to printable string, for log files for example.
3735 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3737 * Made basic router to router connections working. At least they
3738 can now connect to each other but nothing really works the way
3739 they are supposed - yet.
3741 * Added new initiator token to RouterConnection configuration
3742 file in silcd/serverconfig.[ch]. It is used to tell whether we
3743 are the initiator to the remote router or whether we'll expect
3744 the other end to connect.
3746 * Moved registering of listener task to silc_server_init, hence
3747 the server starts listenning as soon as it is run, even if it
3748 does not have connections to other routers. Let's see how well
3751 * Changed default connection retry timeouts for more suitable in
3754 * Removed cipher and such arguments from silc_idlist_add_client
3755 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3756 Added new function silc_idlist_add_data to add the keys and stuff
3759 * Added SilcIDListData structure and added it to SilcClientEntry
3760 and SilcServerEntry as their first field in the structure. This
3761 way we can explicitly cast the ID entries to the SilcIDListData
3762 structure and get common data for the entries. In past, we had
3763 to first check what type of connection it is and then cast it to
3764 correct ID entry type. Now, we can directly cast the opaque
3765 pointer to the SilcIDListData (no matter what ID entry it actually
3766 is) and get the data needed.
3768 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3771 in some circumstances even if threre were timeout tasks, though not
3772 IO tasks, but tasks anyway. Now fixed.
3774 * Defined SilcServerConnection structure to hold connection specific
3775 stuff about directly connected servers and routers. The definition
3776 is currently in silcd/server_internal.h. I thought about having
3777 a bit more important role fro this struct but for now it is used
3778 only when connecting to other server (or router actually).
3780 * Added connecting retry support in server when connecting to
3781 router(s). The retry feature implement exponential backoff
3782 algorithm. Also, added SilcServerParams structure to hold default
3783 parameters for server. For now, it include these retry settings
3784 and are hard coded. After server is moded to be as Silc Server
3785 Library this structure will be more important.
3787 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Changed client librarys channel->clients table to SilcList and
3790 changed code accordingly.
3792 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * Changed client's channel table to SilcList and changed code
3795 accordingly. Also changed SilcChannelClientEntry to include back-
3796 pointer to the channel so that client entry can use that structure
3797 as list as well and we have fast cross-reference to the channel.
3798 This change dramatically decreased the complexity of channel
3799 handling with client entry and vice versa (removed one extra
3800 loop when searching for channel entry from many functions).
3802 * Changed server->sim from table to SilcDList and changed code
3805 * NAMES command can now be used from user interface. It will show
3806 the user list on the channel, neatly.
3808 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3809 Code now saves realname of the user if it becomes available.
3811 * Renamed configure.in to configure.in.pre and made ./prepare
3812 script to automatically add correct version string to
3813 configure.in which it creates from configure.in.pre.
3815 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * NAMES command reply now shows users mode with the nickname when
3820 * Moved silc_client_ch[u]mode[_char] functions from
3821 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3822 place sucks, they are utility functions and should be in some
3825 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3827 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3830 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Added TRQ (efficient deque and list library) into lib/trq. This is
3835 a very good list library that is currently used in the SILC. Defined
3836 SilcList API over the library because I didn't like the API very
3837 much. See lib/trq/silclist.h for the API and examples of how to
3838 use the API. Fixed various places in the code to use the new
3839 SilcList API. The SilcList is meant for lists that has a structure
3840 already defined as a list. It is not suitable to add just some
3841 context to the list (in TRQ, the context is the list actually).
3843 So, I defined SilcDList that can be used for the purpose where
3844 predefined list structure does not exit. This can be used as
3845 such list. Now some context just can be added to the SilcDList.
3846 Currently this list is not used in the SILC just yet, though there
3847 are a lot places where this can replace dynamically allocated
3848 tables and I will fix these places, later, to use SilcDList.
3849 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3850 and use TRQ internally).
3852 Also fixed some annoying warning messages that the original TRQ
3853 code generated. Also minor changes to TRQ's Makefile.in.
3855 * Added support for querying by Client ID to both WHOIS and
3856 IDENTIFY commands into server, as required by the protocol.
3858 * Removed method function pointers from SilcBuffer structure. They
3859 weren't used to anything and just increased the context size for
3860 no good reason. This change also made silc_buffer_alloc and
3861 silc_buffer_free functions inline functions.
3863 * Disabled command flooding detection support until it's fixed so
3864 that it accepts commands in but does not execute them more than once
3867 * Added silc_net_localhost(), to return local hostname, into
3868 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3869 that must be initialized before calling silc_client_init.
3871 * Added new function: silc_server_send_notify_on_channels to send
3872 notify messages to all channels client has joined. It is assured
3873 that the message is sent only once per client.
3875 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3876 lib/silcutil/silcutil.[ch] as silc_format function. The new
3877 function is generic and is used by server as well, not only by
3878 the logging routines.
3880 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3881 the provided version string was not acceptable. Added new function:
3882 silc_ske_check_version into lib/silcske/silcske.h. The function
3883 must be implemented by the application (client or server) and it
3884 does not reside in the SKE library. The function checks the version
3885 string remote end sent.
3887 * Added back pointers (to opaque context and to SilcSocketConnection)
3888 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3890 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3891 duplicate packet context structure.
3893 * Changed `notify' client operation to send same arguments as client
3894 receives from server except for ID's. ID's are mapped to correct
3895 ID entry and that is returned. Also, if channel entry is not sent
3896 by server but the notify is for channel the channel entry is sent
3897 to application (otherwise application doesn't know that it is for
3898 channel (library gets it from packet's Destination ID)).
3900 * Added silc_client_remove_from_channels into client library to
3901 remove a client from all channels it has joined to. Used when
3902 received SIGNOFF notify from server. Added also new function
3903 silc_client_replace_from_channels to replace old ID entry with
3904 new ID entry on all channels. Used when received NICK_CHANGE
3907 * Fixed ID Cache list handling in silc_idlist_get_client in
3908 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3909 to get (or query) client by ID.
3911 * Updated TODO list.
3913 * Added connection authentication status message defined by the
3914 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3915 support for these into the code in client and server side.
3917 * Added generic function silc_client_send_command to send any command
3918 with variable argument list. Application should use this function
3919 to send commands if the command functions provided by the library
3920 does not suite for the application's user interface needs.
3922 * Added new `failure' client operation. Application is notified about
3923 received failure packet if client is executing a protocol. In this
3924 case the protocol's execution has failed.
3926 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3927 is required by the protocol.
3929 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3930 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3933 * Added status flag to SilcSKE object to indicate realtime status
3934 of the SKE protocol.
3936 * Application receives now exactly same command reply arguments as
3937 the library receives from server. However, if ID is received the
3938 corresponding ID entry is returned to the application (eg. Client
3939 ID is mapped to correct SilcClientEntry entry and that is returned).
3940 Changed command_reply client operation due to this change.
3942 * Changed all ID's in commands and in command replys as ID Payloads.
3943 Change affected both client and server side codes.
3945 All ID's sent in SILC network (with execption of ID's in SILC
3946 Packet header) are sent in ID Payload to support variable length
3949 * Server now notifies nick changes and notifies all clients on
3950 the channels about the new nickname (about the new Client ID,
3953 * Implemented CMODE command to change channel modes. Supports all
3954 channel modes defined by the protocol specs except ban and invite
3955 lists. (Also, private channel key mode is supported but support for
3956 setting private channel key in client is missing, thus, this mode
3957 has no effect on client side (except that server requires that the
3958 client uses private channel key and normal channel traffic does not
3961 Also, invite mode works per se, but INVITE command does not work
3962 yet correctly, so you can set channel as invite only channel but
3963 inviting clients to the channel does not work (it is yet to be
3964 thought what's the best way to do it).
3966 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3967 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3968 Implemented CUMODE command to change user's mode on the channel.
3969 Supports all modes defined by the protocol specs.
3971 * Added NAMES command reply to return users modes on the channel.
3973 * Removed unnecessary and slow ciphers from lib/silccrypt.
3975 * Set SO_KEEPALIVE option to connection sockets by default.
3977 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3979 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3980 redefined the Notify Payload into protocol specs.
3982 * Added silc_id_payload_parse_id to get ID directly from raw
3985 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3988 accept searching by Client ID as well.
3990 * Added support for LEAVE and SIGNOFF notify types in client library.
3992 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3993 to parse ID Payload from raw data.
3995 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Added flags parameter into silc_ske_assemble_security_properties
3998 function in lib/silcske/silcske.[ch].
4000 * Changed notify client operation to fit better for notify messages
4001 sent by server. The notify payload received from server is now
4002 passed to the application (after parsing it to SilcNotifyPayload).
4003 It is application's responsibility to retrieve the arguments
4004 from the payload and show the message the way it wants. The message
4005 sent by server is implementation specific.
4007 * Changed public keys to comply with the protocol specification.
4008 Old public keys are not supported anymore and are not compatible.
4010 * Removed nickname from Channel Payload as the latest draft removed
4011 it. The client must resolve the nickname from the NAMES command
4012 reply received when it joined the channel.
4014 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4016 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4018 * Fixed some errors in protocol specification drafts.
4020 * Created lib/silccore/silcnotify.c to implement Notify Payload
4021 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4022 generic payloads described by protocol specifications. The file
4023 includes implementations for ID Payload and Argument Payload.
4025 * Changed Command Payload implementation to use the new Argument
4026 Payload. Changed command_xxxx_payload to command_payload_xxxx
4027 to comply with SILC coding conventions.
4029 * Added suppport for Argument Payload handling in Notify Payload
4030 implementation as protocol requires it. Added the new support
4031 into server and client lib as well.
4033 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Added support for multiple nicknames on same channel. [n] is
4036 added locally to the nickname if there are more than one same
4037 nicknames on the channel.
4039 * Server now sends all nicknames that matched WHOIS request.
4040 Client also shows the list received from server.
4042 * Added TOPIC command to client side. User can now set and show
4043 current topic on channel.
4045 * Added MOTD command to client and server. Also, server sends the
4046 motd when client connects to the server.
4048 * Changed version strings to comply ISO 8601.
4050 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Fixed protocol error handling in client library. It should now
4053 cope even if the SKE fails for some reason.
4055 * Made new protocol specification drafts for submitting to IETF.
4057 * Implemented TOPIC command to server in silcd/command.c.
4059 * Added two new notify types into lib/silccore/silcnotify.h:
4060 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4061 notify nickname change and topic setting/change on a channel.
4063 * API change of command_reply operation in client library. The
4064 application gets now the status type received from server as well.
4066 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4070 * Cras fixed and optimized the packet handling even further and
4071 it should work now. Minor change to the prototype of function
4072 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4074 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4076 * Added new function into lib/silcutil/silcschedule.[ch]:
4077 silc_schedule_with_fd to select() a specified fd. The function
4078 returns after timeout expires or data arrives or goes. The
4079 function is used by packet routines to wait that all data is
4080 received from network.
4082 * Fixed data reading from network in lib/silccore/silcpacket.c.
4083 The code now assures that all data is read from the fd and then
4084 continues packet processing. This was a bug fix since the code
4085 used to drop some data in some circumstances.
4087 * Added new function into lib/silcclient/client.[ch]:
4088 silc_client_start_key_exchange to start key exchange after
4089 connection has been established to server. The code internally
4090 now uses this funtion but its main purpose was to provide it
4091 for applications that perform their own connecting. After
4092 application has created a connection it merely calls this
4093 function to start the key exchange between client and server.
4094 The library takes care of everything else after that.
4096 Updated also lib/silcclient/README to explain the usage of
4099 * Do not send to application information that connection has
4100 been established. Application gets notified it by connect
4103 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4105 * Applied cras's patch to add silc_schedule_one function. The
4106 function runs scheduler once and returns.
4108 * Fixed the scheduler after cras messed it up. The timeout
4109 handling works now as it's supposed to work.
4111 * Added into lib/silccore/ silcnotify.h to include notify
4112 message types support. Changed silc_server_send_notify*
4113 functions, in server.[ch], to support those new notify types.
4114 Added the support for the notify types into client library,
4115 as well. Added new notify client operation into ops.h in
4118 * Changed silc_server_packet_send_to_channel to send normal
4119 packets instead of just channel message packets. The function
4120 is now used to send the notify packets to channels. It is not
4121 used to send channel message packets anymore, as server never
4124 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4125 va_arg()s as it seems to require it nowadays. I guess, if SILC
4126 is compiled with older va_arg() the new code should work anyway.
4128 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Splitted core library. Core library (lib/silccore) includes
4131 now only SILC protocol specific core (and common) components.
4132 Created new utility library (lib/silcutil) that includes more
4133 generic purpose stuff. The stuff for util library was taken
4134 from the old core library. This was minor and easy split.
4136 * Created SILC Client Library (lib/silcclient) that includes
4137 implementation of the SILC client without user interface. This
4138 was major move from silc/ directory. The code has been changed
4139 so that it is transparent towards the user interface. The
4140 silc/ directory includes now the same user interface as before
4141 and it uses the new client library. Read lib/silcclient/README.
4142 Basicly, the client library performs everything else related
4143 to SILC except user interface handling. Also, configuration
4144 files are considered to be part of user interface and library
4145 does not handle them.
4147 This change also changed a lot of structures, function naming etc.
4148 Most important change was that SilcClientWindow object was
4149 renamed to SilcClientConnection in the client library. Created
4150 also new file lib/silcclient/ops.h. Also added new files
4151 silc/local_command.[ch] and silc/client_ops.[ch].
4153 All these changes were made to make it easier for user interface
4154 designers to create what ever user interface for the SILC client
4157 It is also expected that the server will be moved to lib
4158 directory as well and SILC Server Library will be created;
4159 sometimes in the future.
4161 * Removed Local commands from lib/silccore/silccommand.h as
4162 they are application specific and new client library does not
4163 handle any of those anymore.
4165 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4166 old client implementation in silc/.
4168 * Added support for callback functions in SILC_LOG_* macros.
4169 Application can now set its own callbacks that will be called
4170 instead of using the default functions that will always print
4171 the debug messages to stderr (or stdout). Also, debugging can
4172 now be disabled by setting silc_debug to FALSE and re-enabled by
4173 setting it to TRUE. Note, that logging will still work even
4174 if debugging is disabled.
4176 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4177 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4178 silc_log_reset_debug_callbacks.
4180 * To enable debugging in silc client one must give now -d
4181 option on command line.
4183 * Changed silc_schedule_init to automatically allocate task queues
4184 if they are not allocated before calling it.
4186 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Added GMP 3.1 into math library.
4190 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4193 a channel in SILC network. The packet is used by servers and
4194 routers to notify other routers that user has left a channel.
4195 This little feature was missing until now. Added the feature
4196 to protocol specification as well.
4198 Added functions: silc_server_send_remove_channel_user and
4199 silc_server_remove_channel_user into server.[ch].
4201 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4202 lib/silccore/silcpacket.h. However, they are not implemented
4205 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Fixed joining to a channel and sending channel messages
4208 between server and router. The channel message sending should
4209 now work inside a cell.
4211 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Fixed the private message sending between server and router.
4214 The private message sending should now work inside a cell.
4216 * Added silc_server_replace_id into server.[ch] to replace
4217 existing ID in the SILC network.
4219 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4220 and silc_idlist_replace_server_id into idlist.[ch] in server.
4222 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Fixed the server to server connections. Server can again now
4225 connect to router. Router to router connections probably does
4228 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Added dynamic protocol registering support. Now protocols can
4231 registered and unregistered on the fly. Patch by cras.
4233 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Added lib/contrib directory to hold routines that some platforms
4236 don't have but are needed by SILC.
4238 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4239 into lin/contrib to provide getopt() and getopt_long() for
4240 those who don't have it.
4242 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Added AWAY command to client. When away message is set and
4245 client receives a private message packet the client automatically
4246 replies to the sender with the away message.
4248 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4249 bug seemed to be the cause of recent problems when compiling
4252 * Added version detection support to SKE protocol specification
4253 and added the new changes to the SKE implementation as well.
4254 There were other minor changes in the SKE protocol as well.
4256 Many changes in lib/silcske/silcske.[ch] and in
4257 lib/silcske/payload.[ch].
4259 * Added ^U functionality, clear input line. Patch from cras.
4261 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Mainly small bugfixes on core library. Fixed some debugging
4264 logging and buffer overflow in silclog.c.
4266 * Updated config.sub and config.guess on the distribution tree.
4268 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Added command lagging support in server. Client may execute
4271 commands now only once in two seconds.
4273 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Optimized packet reception. MAC computation and checking is now
4276 also more optimized. A lot previously duplicated code is now
4277 used as generic by both client and server.
4279 * Fixed key pair generation in clientutil.c
4281 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Added into lib/silccore/silcbufutil.[ch] new function;
4284 silc_buffer_realloc.
4286 * Moved generic packet sending/encryption functions to
4287 lib/silccore/silcpacket.[ch] from client and server. Some
4288 rewriting of the functions.
4290 * Moved all generic packet reception/decryption functions to
4291 lib/silccore/silcpacket.[ch] from client and server. The
4292 packet processing is now much cleaner in both client and server.
4293 These were major changes in both client and server.
4295 * Created many common functions in server to do packet sending.
4296 Previously code were duplicated a lot, this has been removed
4299 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Rewrote major parts of the ID cache system. Don't know
4302 whether it is better now or not but at least the API is more
4305 * Major rewrite on ID cache stuff on client because of the ID
4306 cache API changes. Added idlist.c to client.
4308 * Also major rewrite on ID cache stuff on server as well.
4309 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4310 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4311 in hand, instead they are all put into the ID cache system now.
4312 All server_idlist_* routines uses ID cache now instead of
4313 traversing its own lists (those lists does not exist anymore).
4314 SilcIDList though still exists. Also, SilcXXXEntry's are
4317 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Finally made the SKE implementation compliant to the protocol
4320 specification. All mp integers are now binary encoded as
4321 opposed being HEX encoded.
4323 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4326 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4327 functions: silc_[encode/decode]_pem. Also added function
4328 silc_encode_pem_file to PEM encode with newlines ('\n') for
4331 * SILC public keys are now encoded either PEM or binary. Same
4332 option is for private keys as well. By default private keys
4333 are binary encoded and public keys PEM encoded. Silly HEX
4334 encoding were removed.
4336 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4337 function to create fingerprints.
4339 * Fixed a bug in SHA1; does not change the original data anymore.
4341 * Partly implemented INFO command on client and server side.
4342 Fixed CLEAR command. Changes to SERVER command; show current
4343 server(s) when giving command without arguments. Added
4344 VERSION command to client.
4346 * Added check to server that unregistered connections cannot
4347 execute commands (unless it is specificly allowed).
4349 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Fixed screen refresh.
4353 * Fixed channel joining bug from client. On some circumstances
4354 client tried to join to a channel it had already joined.
4356 * Added public key verification process into client's protocol.c.
4357 The client now verifies the public key from user and saves
4358 it into ~./silc/serverkeys/ directory.
4360 Added into: clientutil.[ch]: silc_client_verify_server_key.
4362 * Changed SKE protocol's silc_ske_initiator_finish function
4363 to accept callback function that verifies the received public
4364 key. Removed old silc_ske_verify_public_key function.
4366 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4369 silc_pkcs_private_key[_data]_set.
4371 * Made the password and public authentication more cleaner in
4372 server's protocol.c.
4374 * Removed historic and obsolete protocol `channel_auth' from
4375 both client and server.
4377 * Removed wrong way of sending command status messages from
4378 server to client in server's command.c. The old way violated
4379 protocol specification.
4381 Changes to silccore/silccommand.[ch]: removed
4382 silc_command_encode_status_payload -> not needed anymore,
4383 changed silc_command_encode_payload_va to accept extra
4384 argument on variable argument list. The argument type must
4385 now be provided to the function. Also, added new function:
4386 silc_command_encode_reply_payload_va which is same as
4387 normal command_encode_payload_va except command status type
4388 is provided as extra argument.
