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

560 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
562 * Added checking to the server code not to start the server if
563 ciphers and stuff are not configured properly. Affected files
564 silcd/serverconfig.[h] and silcd/server.c.
566 * Changed the layout of the header files of the public interfaces
567 in the SILC libraries. The new layout supports ROBODoc
568 documentation tool (and some others) so that it is easy to create
569 a library reference manual. All the other headers and source
570 code must still follow the CodingStyle document. Also source
571 code must not include these ROBODoc stuffs, only the headers.
572 Furthermore, all public interface headers must now be named
573 by using `silc' prefix, example: silcapi.h, silccipher.h.
574 Some files were renamed due to this. All the other headers
575 must not be used as public interfaces. I will update the
576 CodingStyle document later. Changed following headers, so far:
578 lib/silcclient/silcapi.h
579 lib/silccore/silcauth.h
580 lib/silccore/silcprivate.h
581 lib/silccrypt/silcdh.h
583 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
587 * Removed silc_client_packet_send_flush from the client library
588 as it is not needed. Affected file lib/silcclient/client.[ch].
590 * Added printing of message of unresolved authentication method
591 to the Irssi SILC client. Added it to the module formats.
592 Removed the same message from the client library.
594 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
596 * Added new distribution feature, DISTLABEL. Every distribution
597 can define own preprocessor label that can be used in the
598 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
599 file distributions, acconfig.h.pre and prepare.
601 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
603 * Added Makefile.defines_int to include the actual definitions
604 for Makefile.defines.in. Tested the new distribution system,
605 created distributions and tested installation.
607 * Added AWAY message printing to the Irssi SILC client. Added
608 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
610 * Added SCONNECT command to call the SILC's CONNECT command.
611 Cannot use CONNECT directly since Irssi uses that internally.
612 Affected file irssi/src/silc/core/silc-servers.c.
614 Added ACTION local command. It is same as ME command but takes
615 the channel as mandatory argument.
617 Rewrote some of the Irssi's help files to suite for SILC
620 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
622 * Added Makefile.defines[.in] that should for now on be included
623 in all Makefile.am file in the source tree. That file includes
624 all common compilation definitions for SILC source tree.
626 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Minor changes to the ./prepare script to change the package
629 name according the distribution name to the configure.in.
631 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
633 * Created new distribution system. Added file `distributions'
634 that defines all the distributions that can be created out of
635 the SILC source tree. The ./prepare script now reads that
636 file to determine how to prepare the distributions. The
637 first argument to the ./prepare is the name of the distribution
638 and second is the version of the distribution. If given
639 without arguments it creates the default (toolkit) distribution
640 with the default version (defined in ./prepare).
642 All Makefile.am files that are subject to the distributions
643 are now named as Makefile.am.pre. These are ./Makefile.am
644 and lib/Makefile.am. Others may be changed later.
646 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
648 * Added invite list, ban list, some key management and connection
649 error message printing to module formats in the Irssi SILC client.
651 * Added new silc_client_set_away_message to set the away message
652 that is back to the person who sent private message. The
653 affected file lib/silcclient/silcapi.h and the
654 lib/silcclient/client_prvmsg.c.
656 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
658 * Fixed the private message sending in the Irssi SILC client,
659 added local command KEY to the Irssi SILC client.
661 Added key management and key agreement message formats to the
662 irssi/src/fe-common/silc/module-formats.[ch].
664 Added USERS (alias WHO) printing, server/router operator
665 indication and LIST command printing to the module formats.
667 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
669 * Fixed channel joining notify handling, cumode notify handling
670 from Irssi SILC client.
672 * Added SILC specific module-formats to the Irssi SILC client so
673 that SILC specific message hilighting, colors etc is possible.
674 Affected file irssi/src/fe-common/silc/module-formats.[ch].
676 Added channel mode, channel user mode, actions, notices,
677 whois and whowas printing to the the module-formats.c.
679 * Fixed a bug in channel deletion in the server. The channel
680 is not left to the cache even if the channel founder auth mode
681 is set when there are no users anymore on the channel. Affected
684 * The silc_net_localhost now resolves the entire hostname including
685 the domain name. Affected file lib/silcutil/silcnet.c.
687 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
689 * Changed the ask_passphrase client operation to be ascynchronous.
690 It has now a completion callback and a context that the
691 application must call after it has got the passphrase from
692 the user. Affected files lib/silcclient/silcapi.h,
693 lib/silcclient/protocol.c, lib/silcclient/command.c and
696 Added SilcAskPassphrase callback that the application calls
697 to deliver the passphrase to the library.
699 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
700 The public key verification and especially a certificate
701 verification is asynchronous procedure.
703 Added new SILC_SKE_STATUS_PENDING status to indicate the
704 request is pending and a callback will be called to finalize
707 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
708 indicate that remote end did not send its public key (or
709 certificate), even though we require it. Added check for this
710 condition in the SKE. This was a security bug, now fixed.
712 Defined new SilcSKEVerifyCbCompletion callback that is called
713 when the verification process is completed.
715 The affected files lib/silcske/silcske_status.h and
716 lib/silcske/silcske.[ch].
718 * Changed the verify_public_key client operation to be async
719 as well. Defined SilcVerifyPublicKey callback that is used to
720 indicate the success of the public key verification process.
722 Changed the server and client to use the new async client
725 * Changed the Irssi SILC client's internal scheduler to be called
726 twice as many times as it used to be. As a result the client
727 should be a bit faster now. Affected file is
728 irssi/src/silc/core/silc-core.c.
730 * Added support to Irssi SILC client of asynchronous public key
731 verification and passphrase inquiry. Affected file is
732 irssi/src/silc/core/silc-core.c.
734 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
736 * Do not say "You have left channel %s" in client library.
737 Moved it to the application. Affected files are
738 lib/silcclient/command.c and silc/client_ops.c.
740 * Fixed silc_client_get_clients. Command context was not
741 duplicated and was freed memory in the callback. Affected
742 file lib/silcclient/idlist.c.
744 * Do not say "you are now talking..." on JOIN command in the
745 client library. The appliation must handle it.
747 * Do not say ".. changed topic to" in command reply in the
748 client libary. The application must handle it.
750 * Fixed TOPIC command sending in the client library.
752 * Fixed a memory leak in silc_client_command_free in the file
753 lib/silcclient/command.c.
755 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
757 * Imported a modified version of Irssi client to the source tree.
758 The Irssi will be used to create a new client called
759 Irssi SILC. Imported to irssi/.
761 Added silc_core_init_finish function to the Irssi. Affected
762 file irssi/configure.in.
764 A lot changes in the Makefile.ams around the irssi tree.
766 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
768 * Do not rehash if the new size is same as the old size of the
769 hash table, in the silc_hash_table_rehash*. The affected file
770 lib/silcutil/silchashtable.c.
772 * Replaced hash_table_del_by_context calls from the server
773 (when channel->user_list and client->channels) to the
774 hash_table_del as it is sufficient and faster.
776 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
778 * Added silc_hash_table_list, silc_hash_table_get and the
779 SilcHashTableList structure to provide an alternative way to
780 traverse the hash table. The affected files are
781 lib/silcutil/silchashtable.[ch].
783 * Changed the server's idlist routines to use the hash table
784 routines to optimize the code.
786 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
788 * Replaced the client entry's `channel' list and channel entry's
789 `user_list' list to hash tables for optimized lookup. Changed
790 the code to use the hash table interface around the code.
791 Affected file lib/silcd/idlist.[ch].
793 * Added `auto_rehash' boolean argument to the function
794 silc_hash_table_alloc to indicate whether the hash table should
795 auto-rehash when it thinks is appropriate time. It will
796 increase the hash table size if the there is twice as much
797 entries in the table than the size of the table, and will
798 decrease the size if there are twice as less entries than
799 the size of the table.
801 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
803 * Fixed silc_xxx_get_supported to not crash at some circumstances.
805 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
807 * silc_idcache_purge_by_context deletes the entry now by context
808 as it is supposed to do. Affected file lib/silccore/idcache.c.
810 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
811 client is not anymore valid (WHOWAS givens the info) and not
812 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
814 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
816 * Removed the `data' and `data_len' arguments from the ID Cache
817 interfaces and added `name' argument. ID Cache does not handle
818 anymore the binary data only a names associated with given ID.
820 * When hashing a Client ID with silc_hash_id the entire ID is
821 not hashed anymore, instead only the hash of the Client ID is
822 hashed. This way we can access the Client ID from the cache
823 with Client ID but with the hash of the ID (which is a hash of
824 the nickname) as well without any difference in performance.
826 Added also silc_idcache_find_by_id_one_ext to do one on one
827 searching when we have the actual ID. Added also function
828 silc_hash_client_id_compare. The affected files are
829 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
831 * When hashing the name associated with a ID it is always done
832 in lowercase. This way we can access the cache without worrying
833 about case-sensitivity, even though, for example nicknames are
836 * Fixed a bug in server with channel message sending. It put
837 wrong ID type as destination ID. The affected file
840 * silc_idcache_del_by_context now deletes from all hash tables
841 by context. Affected file lib/silccore/idcache.c.
843 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
845 * Changed the client library to use the new ID Cache interface.
846 Changes around the source tree.
848 * Added silc_hash_table_rehash_ext to rehash with specific
849 hash function. Affected file lib/silcutil/silchashtable.[ch].
851 * Added silc_hash_string_compare to compare two strings in the
852 hash table. Affected file lib/silcutil/silcutil.[ch].
854 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
856 * Added new function silc_idcache_del_by_context into the
857 lib/silccore/idcache.[ch].
859 * Changed the server's ID list routines to use the new ID Cache
860 interface. Changes around the source tree.
862 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
864 * Added silc_hash_table_del[_by_context]_ext functions in to the
865 lib/silcutil/silchashtable.[ch].
867 Removed silc_hash_table_find_all* routines and added new
868 silc_hash_table_find_foreach to replace them.
870 Added silc_hash_table_replace_ext function as extended
871 replacing function. Separated the simple hash table interface
872 from the extended hash table interface in the file
873 lib/silcutil/silchashtable.h.
875 * Fixed minor bugs and changed it to use some of the new
876 hash table functions in lib/silccore/idcache.c
878 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
880 * Added new function silc_hash_table_find_all to return all keys
881 in the hash table by the specified key. As the hash table is
882 collision resistant it also makes it possible to have several
883 duplicate keys in the hash table. This function may be used to
884 find all of the keys from the hash.
886 Added user_context arguments to the SilcHashFunction,
887 SilcHashCompare and SilcHashDestructor to deliver user specified
890 Added new fuctions silc_hash_table_find[_all]_ext to do
891 extended lookup with specified hash and compare functions and
892 specified user contexts.
894 Added new function silc_hash_table_add_ext to add the key
895 with specified hash function and user context.
897 Added new function silc_hash_table_foreach to traverse all
898 entrys in the hash table. Added SilcHashForeach callback
901 Added new function silc_hash_table_del_by_context to delete
902 the entry only if the context associated with the key matches.
904 Affected files are lib/silcutil/silchashtable.[ch].
906 * Removed silc_hash_[server/client/channel]_id and added just
907 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
908 silc_hash_id_compare to compare two ID's using as the hash table
909 comparison function. Added also silc_hash_data to hash
910 binary data and silc_hash_data_compare to compare it.
912 * Removed silc_idlist_find_client_by_hash as it is not needed
913 anymore. Affected file silcd/idlist.[ch].
915 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
916 to use internally the SilcHashTable. The new ID Cache is a lot
917 faster than the old one. Some of the ID Cache interface was also
918 rewritten and obsolete and stupid functions were removed.
920 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Added entry_count field to the SilcHashTable to keep the number
923 of the entries in the table. Implemented the function
924 silc_hash_table_rehash. Added new function
925 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
927 Fixed a minor bug in silc_hash_table_free.
929 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
930 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
931 into the lib/silcutil/silcutil.[ch].
933 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
935 * Implemented a collision resistant hash table into the
936 lib/silcutil/silchashtable[ch]. See the header and the source
937 for the SilcHashTable API.
939 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
941 * Merged dotconf version 1.0.2 into lib/dotconf.
943 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Do not compile anything in lib/silcsim/* if the SIM support
946 is not enabled. The tree should now compile without problems
949 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
951 * Compiled the SILC under cygwin. Compiled and tested briefly
952 without problems. More tests needed. The SIMs didn't compile
955 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
957 * Fixed possible crash in silc_get_username in the
958 lib/silcutil/silcutil.c.
960 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
962 * Fixed a va_arg in silc/client_ops.c.
964 * Oops, RC5 routines were named AES and caused some problems
965 when not using SIM's. Affected file lib/silccrypt/rc5.c.
967 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Added new SilcIDIP structure into the lib/silccore/id.h and
970 replaced the old `ip' fields from all SILC ID's to that type.
971 This is a step towards IPv6 support.
973 The silc_id_get_len takes now the ID as an extra argument.
974 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
975 both IPv4 and IPv6 based ID's.
977 The affected files are lib/silccore/id.[ch] and other files
978 around the tree using these routines.
980 * Removed the ID length arguments in server from various
981 silc_server_send_notify_* routines -> they are not needed
984 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
986 * Fixed memory leak in silc_encode_pem_file in the file
987 lib/silcutil/silcutil.c.
989 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
991 * Check minor version as well in the SKE. Affected files are
992 silcd/protocol.c and lib/silcclient/protocol.c.
994 * Added --identifier option to the server so that an identifier
995 can be when creating the public key for the server. Affected
996 file is silcd/silcd.c.
998 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
999 lib/silccrypt/silcpkcs.c.
1001 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1003 * Register default ciphers and stuff when using -C option with
1004 the server. Affected file sildc/silcd.c.
1006 * Put back the servers public key filename format, it is better
1007 than the new one. For now, the client keys are saved with the
1008 new filename format. The affected file silc/client_ops.c.
1010 * Implemented the Cipher API for the rest of the ciphers that
1011 did not implement it or implemented it the wrong way.
1013 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Register default ciphers and stuff when using the -S option
1016 in the client. Affected file silc/silc.c. Same also when
1017 creating new key pair with -C option.
1019 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1021 * Fixed the silc_verify_public_key client operation function to
1022 save the public keys differently. The fingerprint is now
1023 used as filename and not the hostname. This way also the
1024 client keys are saved uniquely and not with hostnames. The
1025 affected file is silc/client_ops.c.
1027 * Trimmed the silc_hash_fingerprint function to remove extra
1028 whitespaces from the end of the fingerprint. The affected
1029 file is lib/silccrypt/silchash.c.
1033 * Added silc_cipher_register_default function to register all
1034 default ciphers. It can be used when configuration files
1035 does not exist and the application does not want any specific
1036 ciphers in any specific order.
1038 The SilcDList is now used as silc_cipher_list dynamically
1039 allocated cipher list. Removed the static list all together
1040 and now all ciphers must be allocated to the dynamic list.
1041 The silc_cipher_alloc routine was changed to check only the
1044 All silc_cipher_* routines that used to return int returns
1047 The affected files lib/silccrypt/silccrypt.[ch].
1049 * The same thing was done to silc_hash_* as for silc_cipher_*
1050 routines. Affected files lib/silccrypt/silchash.[ch].
1052 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1053 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1054 Added also silc_pkcs_[un]register[_default] functions.
1055 Removed the data_context from the PKCS API.
1057 * Added silc_hmac_register_default function to register default
1058 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1059 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1060 to unregister all hmacs at once.
1062 * Register the default ciphers, hash functions, PKCSs and HMACs
1063 if client's configuration file does not exist. The affected
1066 * The client did not load the hash functions from the SIM
1067 modules at all. Added support for this. Affected file is
1068 silc/clientconfig.c.
1070 * When decoding public key with silc_pkcs_public_key_decode, check
1071 the supported algorithm only if PKCS are registered. Affected
1072 file lib/silccrypt/silcpkcs.c. The same was done with the
1073 silc_pkcs_private_key_decode.
1075 * Fixed the SILC List routines to keep the list always in order.
1076 It used to change the list's order when traversing the list but
1077 not it preserves the order. Affected file lib/trq/silclist.h.
1079 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1081 * Added the client library to use the SilcSocketConnection's
1082 reference counter (by silc_socket_dup) to prevent the bug that
1083 the socket object may be freed underneath async operation.
1085 * The name resolv library checking fixes in the configure.in.pre.
1088 * Created new version of the protocol drafts for future
1089 development. The -03 drafts are the ones that will be changed
1090 in the trunk now and the -02 will remain as they are.
1092 * Send list of CUMODE notifys to the router when announcing
1093 the channel users to the router. Affected file silcd/server.c.
1094 If the router receiving channel founder CUMODE for a channel
1095 that already has channel founder it will send CUMODE notify
1096 to the sender to remove the channel founder rights from the
1097 announced client. Affected file silcd/packet_receive.c.
1099 * The CUMODE notify may now use Server ID as well as the entity
1100 who changes the mode. Updated protocool specs.
1102 * Updated INSTALL and README files.
1104 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1106 * New web pages in the http://silc.pspt.fi. The pages was
1111 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1113 * Implemented the [DenyConnectin] config section in the server.
1114 Added silc_server_config_denied_conn to check whether incoming
1115 connection is denied. Affected file silcd/serverconfig.[ch].
1117 * Do not check the ports when checking the incoming configuration
1118 data if the port is 0, meaning any. Affected file is
1119 silcd/serverconfig.c.
1121 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1123 * Fixed buffer overflow in silc_string_compare in the file
1124 lib/silcutil/silcutil.c.
1126 * Fixed double free in silc_server_command_leave in the file
1129 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * Fixed the version checking in the server. Affected file is
1134 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1136 * Fixed the configuration data fetching when accepting new
1137 connections in the server. Affected file silcd/server.c.
1139 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1141 * Added `sender_entry' argument to the function
1142 silc_server_packet_relay_to_channel so that we can check
1143 whether some destination actually belongs to the same route
1144 the sender belongs (ie, we must not resend the packet to the
1145 sender). Affected file silcd/packet_send.[ch].
1147 * Added `servername' field to the SilcClientEntry in the server
1148 to hold the name of the server where client is from. Affected
1149 file is silcd/idlist.h.
1151 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1153 * Moved the channel message encrypting in the router betwen
1154 router connections from silc_server_channel_message to the
1155 silc_server_packet_relay_to_channel since we want to check
1156 whether we have anybody channel before encrypting anything.
1157 Affected files silcd/packet_[receive/send].c.
1159 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Fixed the [AdminConnection] server config section to support
1162 multiple entries. Affected file silcd/serverconfig.c.
1164 * Added support into the server to check the validity of the
1165 incoming connection before executing any KE or authentication
1168 * The connection configuration is now saved to the KE and
1169 connection auth protocol contexts and not fetched anymore in
1170 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1172 * The local hosts listenning address and port is also resolved
1173 now when starting the server. We want to have the socket object
1174 to include the real address and port for the listener. Added
1175 new function silc_net_check_local_by_sock into the files
1176 lib/silcutil/silcnet.[ch].
1178 * Fixed a broadcast bug in server -> do not broadcast if we
1181 * Fixed a routing bug. Do not route broadcast packets ever.
1182 Broadcast packets must be processed always and not routed since
1183 they may be destined to some other host than yourself and thus
1184 would get routed without no good reason. Affected file is
1187 * Added function silc_server_config_is_primary_route to check
1188 whether primary router connection has been configured (a router
1189 configuration that we are initiating). If there is not, we
1190 will assume that there is only two routers in the SILC network
1191 and we will use the incoming router connection as our primary
1192 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1194 * Changed the order of the broadcasting. Broadcast _after_ the
1195 packet has been processed not before. Affected file is
1198 * Fixed a [ClientConnection] parsing bug. The port was never
1199 parsed correctly thus resulting to port 0. Affected file
1200 silcd/serverconfig.c.
1202 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1203 argument and did not set the broadcast packet flag. Affected
1204 file silcd/packet_send.c. Fixed same bug in the function
1205 silc_server_send_notify as well.
1207 * If we receive NEW_ID packet for our own ID in the server, ignore
1210 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1214 * Removed the nickname from the Private Message Payload.
1215 Updated the code and the protocol specs.
1217 * Updated protocol specs for submitting to the IETF.
1219 * Tweaked the Random Number Generator a bit. Affected file
1220 lib/silccrypt/silcrng.c. Exported a new function
1221 silc_rng_[global]_add_noise which can be used to add more
1224 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1226 * Do not parse packets with different timeout when protocol
1227 is active -> may cause problem with rekey. Affected file
1230 * When server receives signoff notify it must not create
1231 new channel key if the client is on any channels since the
1232 sender of the signoff notify will create it.
1234 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1236 * Added printing of error messages during SKE protocol from the
1237 failure packet sent by server during SKE. Affected file
1240 * Removed the client's failure_callback handling with timeout
1241 and handle it immediately when received.
1243 * The SKE library returned wrong type in SUCCESS and FAILURE
1244 packets. They must be 32 bit MSB not 16 bit MSB.
1246 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1248 * Ok, rewrote the logic of the re-key and now it seems to work.
1249 I tested it on high traffic with frequent re-keys without
1250 problems. Added hmac_receive (and renamed hmac to hmac_send)
1251 in SilcClientConnection in lib/silcclient/client.h and
1252 in SilcIDListData in silcd/idlist.h. Also, removed the
1253 SilcPacketParserContext's cipher and hmac fields as they are
1254 not needed anymore and actually caused some problems when
1255 the ciphers and hmac's changed underneath the packet parser.
1257 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1259 * If re-key protocol is active then process the incoming packets
1260 synchronously since we must assure that icoming packets encrypted
1261 with the old key is processed before the new keys is set to
1262 use. This is true other packets than for REKEY packets.
1263 Affected file silcd/server.c. The same was done to client library
1264 as well, affected file lib/silcclient/client.c.
1266 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Fixed bug in client and server to accept the force send if
1269 the packet is send from silc_[server/client]_packet_process
1270 function. Otherwise the packets are never delivered, oops.
1272 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1274 * Disable force sending of packets when REKEY protocol is active.
1275 We must assure that no packet is sent directly when rekey is
1276 performed. All packets must be sent through packet queue.
1277 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1278 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1279 function is silc_[server/client]_packet_send_real to check
1282 * Replaced the SIM paths from example config files to
1283 /usr/local/modules. Also, make install creates now
1284 /usr/local/silc/logs directory to hold all the SILC server
1287 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Made the configure.in.pre work on Solaris. Patch by salo.
1291 * Made all ciphers compatible with non-x86 machines. Defined
1292 CBC mode macros into lib/silccrypt/ciphers_def.h.
1294 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1296 * Fixed the make install.
1298 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1300 * When MAC computation fails the silc_packet_decrypt returned 0
1301 even though it was supposed to return -1. Fixed this. The
1302 affected file is lib/silccore/silcpacket.c.
1304 * Do not replace the config files in /etc/silc (in make install)
1305 if they already exist. Affected file ./Makefile.am.
1307 * Do not send re-key packets immediately but through packet queue.
1308 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1310 * Changed silc_net_check_host_by_sock to return FALSE if the
1311 IP/DNS could not be resolved. Though, it returns the IP address
1312 now even if it could not resolve it (but returns also FALSE).
1313 Affected file lib/silcutil/silcnet.[ch].
1315 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1317 * Added silc_pkcs_decode_identifier to decode the public key's
1318 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1319 Added also silc_pkcs_free_identifier. Added also new context
1320 SilcPublicKeyIdentifier.
1322 * Added -S option to the silc client. It is used to dump the
1323 contents of the specified public key file.
1325 * Changed the PKCS api to return the public key length when
1326 setting the public key.
1328 * Fixed a fatal bug in the public and private key file loading.
1329 Affected file lib/silccrypt/silcpkcs.c.
1331 * Execute the packet parsing for client with zero (0) timeout
1332 if the protocol is active. Affected file silcd/server.c.
1334 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1336 * Made the key generation options to the silcd program. Added
1337 -C option, equivalent to client's option.
1339 * Added new [ServerKeys] config section to the server. It
1340 configures the server's public and private key.
1342 * Defined generic Public Key Payload into the protocol
1343 specification to send specific type of public keys and
1346 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1347 public key or certificate.
1349 * Implemented the GETKEY command to the server and to the
1350 client library and on user interface.
1352 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1354 * Made preliminary `make install' work.
1356 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1358 * Added SilcServerRekey context into silcd/idlist.h.
1360 * Added the PFS support as defined in the specification to the
1361 SKE protocol. Affected files lib/silcske/*.c.
1363 * Added `ske_group' field to the SilcServerRekey context to hold
1364 the number of the SKE group that is used with PFS in re-key.
1365 Affected file silcd/idlist.h.
1367 * Added PFS re-key support to the server. Affected file is
1370 * Added silc_protocol_cancel to cancel execution of the next
1371 state of the protocol. Affected file is
1372 lib/silccore/silcprotocol.[ch].
1374 * Added the re-key support with and without PFS to the client
1375 library. Re-key is performed once in an hour, by default.
1377 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1378 Added silc_client_rekey_callback and silc_client_rekey_final.
1379 Affected files are lib/silcclient/protocol.[ch] and
1380 lib/silcclient/client.[ch].
1382 * Removed the `hmac_key' and `hmac_key_len' fields from the
1383 SilcClientConnection structure; not needed. Affected file is
1384 lib/silcclient/client.h.
1388 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Do not ask whether user wants to use the negotiated private key
1391 for private messages, just use it. Affected file is
1392 silc/local_command.c.
1394 * Added `send_enc_key' and `enc_key_len' fields to the
1395 SilcIDListData structure since they are needed in the re-key
1396 phase. Affected file is silcd/idlist.[ch].
1398 * Implemented the simple re-key protocol into the server.
1399 Affected files silcd/server.c and silcd/protocol.[ch]. The
1400 re-key will be performed once in an hour, by default.
1402 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1403 Added silc_server_rekey, silc_server_rekey_callback and
1404 silc_server_rekey_final.
1406 * Removed Tunneled flag from the protocol. Updated the code
1407 and the specifications.
1409 * Adde `pfs' field to the SilcIDListData to indicate whether
1410 the PFS is to be performed in the re-key. Affected file is
1413 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1415 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1416 int64 of at least the xintXX size. If void * is less that 4
1417 bytes uint32 * will be used. Defined bool as boolean.
1419 * Changed _ALL_ unsigned long and unsigned int to uint32,
1420 unsgined short to uint16 in the source tree.
1422 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1423 not handle clients that has entry->data.registered == FALSE.
1424 They are not in the network anymore. Affected file is
1427 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * Implemented the sending of the SERVER_SIGNOFF notify in the
1430 server. Affected file is silcd/server.c.
1432 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1433 Added also silc_notify_payload_encode_args into the
1434 lib/silccore/silcnotify.[ch].
1436 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1437 Affected file silcd/packet_receive.c.
1439 * Implemented the SERVER_SIGNOFF notify handling in the client
1440 library. Affected file lib/silcclient/client_notify.c. Also,
1441 implemnted the printing of the SERVER_SIGNOFF info to the
1442 application. Affected file silc/client_ops.c.
1444 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1445 if the deleting was successful. Affected file silcd/idlist.[ch].
1447 * Added support for public key authentication in the connection
1448 authentication protocol in the client library. Affected file
1449 lib/silcclient/protocol.c.
1451 * Changed the server's silc_idlist_get_clients_by_* interface
1452 to support already allocated array so that new entries may be
1453 added to pre-allocated array. Affected file silcd/idlist.[ch].
1454 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1455 and command replies.
1457 * All command reply functions in the server now calls the
1458 pending command callback even if error occured. This way the
1459 error will be delivered to the client as well. Affected files
1460 silcd/command.c and silcd/command_reply.c.
1462 * Fixed INFO command to return local server's info if no server
1463 was provided. Affected file lib/silcclient/command.c.
1465 * Removed RESTART command for good. Updated the code and the
1468 * Rewrote parts of the task system. It is a bit simpler now.
1469 Removed unsued task priorities. The affected files are
1470 lib/silcutil/silctask.[ch].
1472 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1474 * Moved the USERS printing from the library to the application.
1475 Affected files lib/silcclient/command.c and silc/client_ops.c.
1477 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1481 * Added channel key re-key support. The re-key is perfomed
1482 only by the router and is done once in an hour. Added `rekey'
1483 field to the SilcChannelEntry in the server. Affected files
1484 silcd/server.c and silcd/idlist.h.
1486 * Added silc_task_unregister_by_context into the file
1487 lib/silcutil/silctask.[ch].
1489 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1491 * Added SILC_UMODE_GONE mode to indicate when the client is not
1492 present in the SILC network. Added also support to the local
1493 command AWAY that will set this mode. Added support of showing
1494 "xxx is gone" in WHOIS command. The USERS command shows the
1495 gone status as well.
1497 * Fixed setting server and router operator privileges in the
1498 server's UMODE command. Affected file silcd/command.c.
1500 * Merged the SKE KE1 and KE2 payloads into one payload. The
1501 new KE payload is equivalent to the old KE2 payload.
1503 Cleaned up the SKE Start Payload parsing. It now uses the
1504 simple buffer unformatting to do the parsing. A lot faster
1507 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1508 to the SKE that is used to indicate whether both of the SKE
1509 parties should perform authentication. By default only the
1510 responder performs authentication. By setting this flag also
1511 the initiator must do authentication. By default it is unset
1512 since in normal SKE case, client to server connection, only
1513 the responder should do authentication. When doing SKE between
1514 two clients both should perform authentication. Updated the
1515 code and the protocol specs.
1517 * A little fix to IDENTIFY command in the server. Search the
1518 client first by hash not nickname. Affected file is
1521 * Fixed the silc_client_close_connection to support closing
1522 the client to client connections wihtout deleting too much
1523 data. Affected file lib/silcclient/client.c.
1525 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1526 are received if protocol used to be active but is not anymore
1527 the application would crash due to NULL pointer dereference.
1528 Affected files silcd/server.c and lib/silcclient/client.c.
1530 * Added `hash' field to the SilcClientConnection to include
1531 the hash function negotiated in the SKE protocol.
1533 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1534 to set the channel founder authentication data. A client can
1535 claim the founder rights later by providing the authentication
1536 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1537 This way the channel founder can regain the channel founder
1538 privileges even it is left the channel. This works only on
1539 local server and the client must be connected to the same
1540 server to be able to regain the founder rights. Updated the
1541 protocol specs accordingly.
1543 Added support to the CMODE command in the client to set the
1544 founder auth data. Read the README to see how to set it.
1546 Added support to the CUMODE command to claim the founder
1547 rights. Read the README to see how to do it.
1549 Added support for the founder authentication to the Channel
1550 Entry in the server. Affected file silcd/idlist.h.
1552 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1553 server's CMODE command. Affected file silcd/command.c.
1555 * Added the following new functions into lib/silccore/silcauth.[ch]:
1556 silc_auth_get_method and silc_auth_get_data.
1558 * The server now saves the remote hosts public key to the
1559 SilcIDListData pointer. Affected file silcd/protocol.c.
1561 * The normal server now does not remove the channel entry from
1562 the cache if the founder authentication data is set. It used
1563 to remove it if the founder was the last one on the channel on
1564 the server and left the channel. The auth data is saved and
1565 if the channel is re-joined later the old entry is used with
1566 the old auth data. Affected files silcd/command_reply.c and
1569 * Removed the `pkcs' field from the SilcIDListData structure
1570 in the server; it is not used. Affected file silcd/idlist.h.
1572 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * Fixed packet processing on slow links. Partial packets were
1575 never re-processed because the incoming data buffer was cleared
1576 by the application. Application must not directly clear the
1577 sock->inbuf, the packet processing routines handle it. Fixed
1578 this in client library and in server.
1580 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * Fixed the WHOIS and IDENTIFY send reply function to really
1583 check whether to send list or just one entry. Affected file
1586 * Cleaned up the LEAVE command's channel key distribution. The
1587 affected file silcd/command.c.
1589 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1590 can enforce the channel mode as well. In that case the ID
1591 includes the ID of the server. The code now enforces the
1592 mode change if the router have different mode than the server.
1594 * The notify client operation with CMODE_CHANGE notify can now
1595 return NULL client_entry pointer if the CMODE was not changed
1596 by client. Application must check for this.
1598 * Added <Server ID> argument to INFO command to support server
1599 info fetching by Server ID.
1601 * Added silc_server_announce_get_channel_users to get assembled
1602 packets of channel users of the specified channel. Affected
1603 file silcd/server.[ch].
1605 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1606 was freed underneath the ID Cache.
1608 * Re-announce clients when the server received CHANNEL_CHANGE
1609 notify from the router. Affected file silcd/packet_send.c.
1611 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1613 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1614 crashed since it did not handle the fact that there is no cipher
1615 called "3" and didn't check the error condition. Now fixed.
1617 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1618 flag. It can be used to send message requests.
1620 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1622 * Implemented the RESTART command in the client.
1624 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1625 notice type messages. Added notice printing to the user
1628 * The channel keys are not re-generated if the channel's mode
1629 is PRIVKEY, ie private key on the channel exists. Affected
1630 files silcd/server.c and silcd/command.c.
1632 * Fixed a little bug in channel message delivery when channel
1633 private keys are set in the server. Affected file is
1634 silcd/packet_send.c.
1636 * Changed the setting on channel->on_channel = TRUE from the
1637 silc_client_save_channel_key to the JOIN command reply. The
1638 key payload is not received if the private channel key is set.
1639 Affected file lib/silcclient/command_reply.c and the
1640 lib/silcclient/client_channel.c.
1642 * When the CMODE_CHANGE notify is sent and the channel private
1643 key mode is removed the channel key must be re-generated in
1644 other cells as well. Added this support for the router in the
1645 silcd/packet_receive.c.
1647 * Added new local command NOTICE to send notice message on
1648 channel. Affected file silc/local_command.[ch].
1650 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1652 * Added new local command ME to the client. It is used to send
1653 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1654 some action. Affected file silc/local_command.[ch].
1656 * Changed channel_message and private_message client operations
1657 to deliver the message flags to the application. Added also
1658 the `flags' arguments to the silc_client_send_channel_message
1659 and silc_client_send_private_message functions. Affected file
1662 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Redefined the Private Message Payload to support private message
1665 keys and to support the new private message flags. Updated
1666 the protocol specs. Flags makes it possible to have for example
1667 CTCP style messages.
1669 * Added new type SilcPrivateMessagePayload and defined an API
1670 for it in the lib/silcclient/silcprivate.[ch].
1672 * Tested private message private keys successfully. Tested the
1673 private message key set, unset and list commands with the new
1676 * Redefined the Channel Message Payload to include the channel
1677 message flags (equal with private message flags) to support
1678 for example CTCP style messages.
1680 * Defined some of the message (for channel and private message)
1681 flags. Updated the protocol specs and added the flags to the
1682 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1684 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1686 * Added SilcKeyAgreementStatus type to the key agreement routines
1687 to indicate the current status and error if one occured.
1688 The status types are defined in the lib/silcclient/silcapi.h.
1690 * Added new local command KEY that is used to set and unset private
1691 keys for channels, set and unset private keys for private messages
1692 with remote clients and to send key agreement requests and
1693 negotiate the key agreement protocol with remote client. The
1694 key agreement is supported only to negotiate private message keys,
1695 it currently cannot be used to negotiate private keys for channels,
1696 as it is not convenient for that purpose.
1698 * Fixed a minor pending callback setting bug in the function
1699 silc_client_get_client_by_id_resolve, now the function works.
1700 Affected file lib/silcclient/idlist.c.
1702 * Added function silc_net_get_local_port to get local bound
1703 port by socket. Added to lib/silcutil/silcnet.[ch].
1705 * Added `sockets' and `sockets_count' fields to the SilcClient
1706 object. They hold the sockets of the listenning sockets in
1707 the client. Listenning sockets may be for example the key
1708 agreement server. Affected file lib/silcclient/client.[ch].
1709 Added functions the silc_client_add_socket and the
1710 silc_client_del_socket. They are exported to the application
1713 * Added ~./silc/clientkeys to support other client's public keys.
1715 * Renamed verify_server_key client operation to verify_public_key
1716 and added one argument to indicate the type of the connection
1717 (server, client etc.).
1719 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1721 * Added silc_server_connection_auth_request to handle the
1722 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1723 silcd/packet_receive.[ch].
1725 * Added silc_server_send_connection_auth_request into the
1726 silcd/packet_send.c to send the connection auth request packet.
1728 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1731 * Fixed the public key authentication in responder side in the
1732 server. The `auth_data' pointer includes the SilcPublicKey
1733 not the path to the public key. Affected file silcd/protocol.c.
1735 * Implemented the public key authentication in the initiator side
1736 in the server. Affected file silcd/protocol.c.
1738 * Removed the [RedirectClient] config section from the server
1739 configuration. Is not needed and I don't want to implement it.
1741 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1743 * Cleaned up the CMODE command in the server. It now works
1744 correctly and supports all the modes defined in the protocol.
1745 Affected file is silcd/command.c.
1747 * Added `hmac_name' field to the SilcChannelEntry in the server
1748 to hold the default HMAC of the channel. It can be set when
1749 creating the channel (with JOIN command). Affected files
1752 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1753 type to indicate the change of the current cipher and hmac
1754 on the channel. Client can safely ignore the <cipher> argument
1755 (if it chooses to do so) since the CHANNEL_KEY packet will
1756 force the channel key change anyway. The <hmac> argument is
1757 important since the client is responsible of setting the new
1758 HMAC and the hmac key into use.
1760 * Fixed the CMODE command in the client library as well.
1762 * Tested CMODE command in router environment successfully.
1764 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1766 * Show the version of the remote client (or server) when connecting
1767 to the server. It is logged to the log file. Affected file
1768 is silcd/protocol.c.
1770 * Fixed the KILLED notify handling in the client library. The
1771 client must be removed from all channels when receiving the
1774 Also, do not remove the client entry when giving the KILL
1775 command but when the KILLED notify is received.
1777 * Removed silc_idlist_find_client_by_nickname from the server.
1778 Not needed anymore. Affected files silcd/idlist.[ch].
1780 * Implemented the CHANNEL_CHANGE notify type handling to the
1781 server. Affected file silcd/server.c.
1785 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1787 * Added silc_server_send_notify_invite to send the INVITE
1788 notify between routers.
1790 * Implemented the INVITE command correctly to the server.
1792 * Implemented the INVITE notify type handling in the server.
1794 * Implemented the INVITE command to the client library and on the
1797 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1799 * Added function silc_server_get_client_resolve to find the
1800 client entry by ID from all ID lists and then resolve it
1801 (using WHOIS) if it cannot be found. Affected file is
1804 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1806 * Implemented the BAN command to the client library.
1808 * The JOIN command in the server now checks the invite list
1811 * Changed the silc_command_reply_payload_encode_va and the
1812 silc_command_payload_encode_va to support that if argument is
1813 NULL it ignores and checks the next argument. Affected file
1814 lib/silccore/silccommand.c.
1816 * Added silc_server_send_notify_ban to send the BAN notify
1817 type between routers.
1819 * Chaned the silc_notify_payload_encode to support that if
1820 argument is NULL it ignores and checks the next argument.
1821 Affected file lib/silccore/silcnotify.c.
1823 * Tested ban lists in router environment successfully.
1825 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1827 * Implemented BAN command to the server, in silcd/command.[ch].
1829 * Removed the BAN and INVITE_LIST modes from the CMODE command
1832 * Added function silc_string_match to regex match two strings.
1833 Affected files lib/silcutil/silcutil.[ch].
1835 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Redefined parts of the SilcChannelEntry in the server to support
1838 the new ban and invite lists.
1840 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1842 * Redefined the INVITE command. The same command can be used to
1843 invite individuals to the channel but also to manage the invite
1844 list of the channel (to add to and remove from the invite list).
1845 Updated the protocol specs.
1847 * Added new command SILC_COMMAND_BAN that can be used to manage
1848 the ban list of the channel. Updated the protocol specs.
1850 * Removed the channel modes: the SILC_CMODE_BAN and the
1851 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1852 in the CMODE command. The equivalent features are now available
1853 using INVITE and BAN commands. Updated the protocol specs.
1855 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1856 in the network about change in the current ban list. The notify
1857 type is not used by the client.
1859 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1860 support the invite lists.
1862 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1864 * Added new function silc_string_regexify that converts string
1865 including wildcard characters into regex string that can
1866 be used by the GNU regex library. Added into the file
1867 lib/silcutil/silcutil.[ch].
1869 Added silc_string_regex_combine to combine to regex strings
1870 into one so that they can be used as one regex string by
1871 the GNU regex library. Added into the file
1872 lib/silcutil/silcutil.[ch].
1874 Added silc_string_regex_match to match two strings. It returns
1875 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1877 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1879 * Imported GNU regex to the soruce tree into lib/contrib.
1880 Fixed some compiler warning from the regex.c.
1882 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1884 * Fixed MOTD command in the server to work in router environment.
1886 * Fixed the MOTD command in the client library to support
1887 the server argument in the command.
1889 * Added `nickname_len' argument to the silc_idlist_add_client
1890 in the server, as the `nickname' argument may be binary data
1893 * Added silc_idlist_get_channels to return all channels from
1896 * Implemented LIST command to the server. Affected file is
1899 * Implemented the LIST command to the client library and on the
1902 * Added [<user count>] argument to the LIST command reply.
1903 With private channels the user count is not shown.
1905 * Updated TODO and README.
1907 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1909 * The client entry's data.registered must be TRUE even with
1910 global client entry on global client list. The data.registered
1911 is used to check whether the client is anymore in the network,
1912 for example with WHOWAS command so it must be valid.
1914 * Fixed the WHOWAS command in the server. It now actually works
1915 in router environment. Added function into silcd/command_reply.c
1916 silc_server_command_reply_whowas_save.
1918 * Added silc_idlist_purge function to the silcd/idlist.c
1919 to periodically purge the ID Cache.
1921 * Fixed INFO command in the server. It works now in router
1922 environment. Added <server name> argument to the INFO command
1923 reply. Updated the protocol specs.
1925 * Fixed minor bug in silc_idcache_purge to not purge if the
1926 expire value is zero.
1928 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1929 they were buggy because of the WHOWAS information.
1931 * Fixed local command MSG to handle the async resolving of
1932 the remote client properly. It used to fail the first MSG.
1933 Affected file silc/local_command.c.
1935 * Added `data_len' field to SilcIDCache context.
1937 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1939 * Update TODO. Todo in commands in the server.
1941 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1944 used by routers as broadcast packet to inform other routers
1945 about the changed user mode.
1947 Implemented the notify handling in the server. Affected file is
1948 silcd/packet_receive.c. Added the function
1949 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1951 * Added new generic Channel Payload and deprecated the New Channel
1952 Payload. The New Channel Payload is now the generic Channel
1955 * Added new argument `mode' to the silc_server_send_new_channel
1956 as it is required in the Channel Payload now.
1958 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1959 and created a new and real SilChannelPayload to represent the
1960 new generic Channel Payload. Implemented the encode/decode
1961 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1963 * Added silc_server_get_client_channel_list to return the list
1964 of channels the client has joined for WHOIS command reply.
1965 Affected file silcd/server.[ch].
1967 * Implemented the channel list sending in the WHOIS command reply
1968 in server and in the client.
1970 Implemented the channel list displaying on the user interface
1971 as well. Affected file silc/client_ops.c.
1973 * Added silc_channel_payload_parse_list to parse list of Channel
1974 Payloads. It returns SilcDList list of SilcChannelPayloads.
1975 Client for example can use this function to parse the list of
1976 channels it receives in the WHOIS command reply. The caller
1977 must free the list by calling silc_channel_payload_list_free.
1978 Affected files lib/silccore/silcchannel.[ch].
1980 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1982 * Added one new argument <user mode> to the WHOIS command reply
1983 to return the mode of the user in SILC. Updated the protocol
1986 Implemented it to the server and client.
1988 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1990 * Fixed the mode printing on the user interface on joining.
1991 Affected file silc/client_ops.c.
1993 * Implemented the UMODE command and user modes in general to the
1994 client library and to the user interface.
1996 * Implemented the UMODE command to the server.
1998 * The server now sends UNKNOWN_COMMAND error status if client sends
1999 unknown command. Affected file silcd/command.c.
2001 * All server commands now handle the command identifier the right
2002 way when sending the command reply to the client. The client can
2003 use to identify the command replies with the identifier.
2005 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2007 * Added silc_server_get_client_route to resolve the route to
2008 the client indicated by the client ID. Affected file is
2011 * Added silc_server_relay_packet as general function to relay
2012 packet to arbitrary destination. This deprecates functions
2013 like _send_private_message_key, _relay_notify etc. Affected
2014 file is silcd/packet_send.[ch].
2016 Removed silc_server_send_key_agreement,
2017 silc_server_send_private_message_key and
2018 silc_server_packet_relay_notify functions from the file
2019 silcd/packet_send.[ch].
2023 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2024 server. Affected file silcd/packet_receive.[ch].
2026 * Implemented the KILL command to the client. Implemented the
2027 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2028 Affected files lib/silcclient/command[_reply].c and
2029 lib/silcclient/client_notify.c. Implemented the KILL notify
2030 printing in the user inteface.
2032 * Fixed a lot silc_parse_nick memory leaks from the client
2033 library in the file lib/silcclient/command.c.
2035 * Changed the silc_server_send_notify_on_channels's `sender'
2036 argument from SilcSocketConnection to SilcClientEntry to
2037 check the sender as entry and not as connection object and not
2038 to send to the client provided as argument. The affected file
2039 is silcd/packet_send.[ch].
2041 * The notify packets that are destined directly to the client used
2042 to not to be processed by the server. Now changed that and the
2043 server processes all notify packets. After relaying the packet
2044 to the client the notify packet is processed in the server.
2046 * The silc_server_free_client_data now checks whether there is
2047 pending outgoing traffic for the client and purges the data to
2048 the network before removing the client entry.
2050 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2052 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2053 an client is killed from the SILC Network. Updated the protocol
2056 Added new function silc_server_send_notify_killed to the
2057 silcd/packet_send.[ch].
2059 * Added function silc_server_packet_relay_notify to relay notify
2060 packets that are destined directly to a client. In this case
2061 the server does not process the notify packets but merely relays
2062 it to the client. Affected file silcd/packet_send.[ch].
2064 Added also silc_server_packet_process_relay_notify to check
2065 whereto relay the notify. Affected file is
2066 silcd/packet_receive.[ch].
2068 * Implemented the KILL command to the server.
2072 * Added the backup schema desgined last fall to the protocol
2073 specs for everyone to see. The specification is in the
2074 *-spec-xx.txt draft and the packet type definitions for the
2075 backup routers is in *-pp-xx.txt draft. Thusly, added also
2076 new packet type SILC_PACKET_CELL_ROUTERS.
2078 * A big security problem in the implementation discovered. The
2079 signoff of an client did not cause new channel key generation
2080 which it of course should've done. The channel keys must be
2081 always re-generated when client leaves (or signoffs) the channel.
2082 The silc_server_remove_from_channels funtion now handles
2083 the channel key re-generation.
2085 * Added `sender' argument to the silc_server_send_notify_on_channels
2086 to not to send the client provided as argument. Affected file
2087 silcd/packet_send.[ch].
2089 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2091 * Implemented OPER and SILCOPER commands into the server and
2094 * Added silc_auth_verify and silc_auth_verify_data to verify
2095 the authentication directly from the authentication payload.
2096 It supports verifying both passphrase and public key based
2097 authentication. Affected file lib/silccore/silcauth.[ch].
2099 * Added `hash' field to the SilcIDListData structure. It is the
2100 hash negotiated in the SKE protocol. Affected file is
2103 * Slight redesigning of the SilcAuthPayload handling routines.
2104 Do not send SilcPKCS but SilcPublicKey as argument.
2106 * Implemented the public key authentication support to the
2107 serverconfig. The public key is loaded from the provided path
2108 and saved as authentication data to void * pointer. Thus,
2109 changed the unsigned char *auth_data to void *auth_data;
2111 * Fixed SHUTDOWN command to send the reply before the server
2112 is shutdown. :) Affected file silcd/command.c.
2114 * Fixed fatal bug in CONNECT command. The hostname was invalid
2115 memory and server crashed. Affected file silcd/command.c.
2117 * Fixed fatal bug in CLOSE command. The server_entry became
2118 invalid but was referenced later in the command. Affected file
2121 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2123 * Fixed fatal bug in failure packet handling. Server ignored
2124 the failure and thus crashed when it came.
2128 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2131 that the command may be executed only once in (about) 2 seconds.
2132 The old SILC_CF_LAG flag is same but allows command bursts up
2133 to five before limiting.
2135 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2136 server code. Various commands now includes the CF_LAG_STRICT
2137 flag to disallow any kind of miss-use of the command.
2139 * Fixed the silc_buffer_unformat to not to allocate any data
2140 if the length of the data is zero. It used to allocate the
2141 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2143 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Changed the format of AdminConnection configuration section
2146 in the server. Added username of the admin to the format.
2147 Affected files silcd/serverconfig.[ch].
2149 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2150 to return admin configuration data by host, username and/or
2153 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2155 * Implemented WHOWAS command to the server. Added the functions:
2157 silc_server_command_whowas_parse,
2158 silc_server_command_whowas_send_reply,
2159 silc_server_command_whowas_from_client and
2160 silc_server_command_whowas_from_server
2162 * Added <Client ID> argument to the WHOWAS command reply. Updated
2163 the protocol specs accordingly.
2165 * Implemented WHOWAS command and command_reply to the client
2168 Implemented the WHOWAS printing on the user interface.
2170 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Added new argument to the WHOWAS command reply, the real name.
2173 It is an optional argument. Updated the protocol specs.
2175 * Added SilcIDCacheDestructor callback that is registered when
2176 the SilcIDCache is allocated. The callback is called when
2177 an cache entry in the ID Cache expires, or is purged from the
2178 cache. Added into lib/silccore/idcache.[ch].
2180 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2181 to destruct the client entries when the cache entry expires.
2182 Other ID Cache's in server and in the client library ignores
2185 * If the ID Cache entry's `expire' field is zero then the entry
2186 never expires. Added boolean `expire' argument to the
2187 silc_idcache_add function in the lib/silccore/idcache.[ch].
2188 If it is TRUE the default expiry value is used.
2190 * Added silc_server_free_client_data_timeout that is registered
2191 when client disconnects. By default for 5 minutes we preserve
2192 the client entry for history - for WHOWAS command.
2194 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2196 * Added support to the server to enforce that commands are not
2197 executed more than once in 2 seconds. If server receives
2198 commands from client more frequently, timeout is registered
2199 to process the commands. Affected file silcd/command.c.
2200 Added new function silc_server_command_process_timeout.
2202 * Changed NICK_NOTIFY handling in client library to check that
2203 if the client's nickname was changed, so there is no need to
2204 resolve anything from the server.
2206 * Removed error printing from the WHOIS and IDENTIFY commands.
2207 If error occurs then it is ignored silently in the client library.
2208 The application, however, may map the received error to
2209 human readable error string. The application currently maps
2210 the NO_SUCH_NICKNAME error to string.
2212 * Made the command status message public to the application. Moved
2213 them from lib/silcclient/command_reply.c to
2214 lib/silcclient/command_reply.h. The application can map the
2215 received command status to the string with the
2216 silc_client_command_status_message function.
2218 * Added check to the server to check that client's ID is same
2219 as the Source ID in the packet the client sent. They must
2222 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2224 * Added dist-bzip hook to the Makefile.am to make bzip2
2225 compressed distributions.
2227 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * Server now enforces the maximum length for the nickname and
2230 the channel as protocol specification dictates. 128 bytes for
2231 nickname and 256 bytes for channel name.
2233 * Moved the WHOIS printing to the application. The client libary
2234 does not print out the WHOIS information anymore, the application
2235 must do it. Renamed silc_client_command_reply_whois_print to
2236 the silc_client_command_reply_whois_save.
2238 The client's idle time is also sent to the application now, and
2239 the idle is shown on screen.
2241 * Added silc_client_command_reply_identify_save to save the
2242 received IDENTIFY entries.
2244 * Do not check for channel private keys in message sending and
2245 reception if the channel does not have the PRIVKEY mode set.
2246 Affected file lib/silclient/client_channel.c.
2248 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2250 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2251 just surfaced after chaning the JOIN procedure.
2253 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2255 * Added silc_client_get_clients_by_list to get client entries
2256 from Client ID list, that is returned for example by JOIN
2257 and USERS command replies. The application should use this
2258 function for example when JOIN command reply is received to
2259 resolve the clients already on the channel (library does not
2260 do that anymore as USERS command reply is not used in the JOIN
2261 procedure anymore). Affected files lib/silcclient/silcapi.h and
2262 lib/silcclient/idlist.c.
2264 * JOIN command reply and USERS command reply returns now SilcBuffer
2265 pointers instead of unsigned char pointers when returning
2266 the client list and mode list.
2268 * Added <Client ID> argument to the JOIN command reply, mainly
2269 for the server to identify for which client the command was
2270 originally sent. Updated protocol specs accordingly.
2272 * Added SilcDlist private_key pointer to the SilcChannelEntry
2273 in the client to support the channel private keys. Affected
2274 file is lib/silcclient/idlist.h.
2276 * Added SilcChannelPrivateKey argument to the function
2277 silc_client_send_channel_message so that application can choose
2278 to use specific private ke if it wants to. If it is not provided,
2279 the normal channel key is used, unless private keys are set.
2280 In this case the first (key that was added first) is used
2281 as the encryption key.
2283 * Implemented the support for channel private key handling.
2284 Implemented the following functions:
2286 silc_client_add_channel_private_key,
2287 silc_client_del_channel_private_keys,
2288 silc_client_del_channel_private_key,
2289 silc_client_list_channel_private_keys and
2290 silc_client_free_channel_private_keys
2292 Affected file lib/silcclient/client_channel.c.
2294 * Added the support for the private keys in the channel message
2295 sending and encryption and in the message reception and
2296 decryption. Affected funtions are
2297 silc_client_send_channel_message and silc_client_channel_message.
2299 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2301 * Added SKE's key verify callback to the client library's
2302 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2304 * Removed the statement that server (or router) must send USERS
2305 command reply when joining to the channel so that the client
2306 knows who are on the channel. Instead, the client list and
2307 client's mode list is now sent in the JOIN command reply to the
2308 client who joined channel. This is better solution.
2310 * Added function silc_server_get_users_on_channel and function
2311 silc_server_save_users_on_channel to the silcd/server.[ch].
2313 * Removed function silc_server_command_send_users from the
2316 * Do not show topic on the client library anymore. The topic is
2317 sent in the command reply notify to the application and the
2318 application must show the topic now.
2320 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2322 * Added client searching by nickname hash into the IDENTIFY and
2323 WHOIS commands in the server as they were clearly missing from
2324 them. Affected file is silcd/command.c.
2326 * Fixed a bug in private message receiving in the client library.
2327 The remote ID was freed and it wasn't supposed, now it is
2330 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Minor fix to the channel payload; allocate the data area, as it
2333 needs to be of specific length.
2335 * If the key agreement port is zero then the operating
2336 system will define the bound port. Affected files are
2337 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2339 * Added new function silc_channel_payload_decrypt into the file
2340 lib/silccore/silcchannel.[ch].
2342 * Moved the channel message etc, check from silc_packet_decrypt
2343 to applications. The library calls now a generic
2344 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2345 when the packet is either normal or special. This was done to
2346 allow more wide range of checking that was not allowed when
2347 the code was in library. Now applications can do virtually any
2348 checks to the packet and return to the library the decision how
2349 the packet should be processed. Affected files are
2350 lib/silccore/silcpacket.[ch].
2352 Added silc_server_packet_decrypt_check to the server and
2353 silc_client_packet_decrypt_check to the client library.
2355 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2356 to send with specified source and destination information.
2358 * Channel message delivery between routers was broken after the
2359 channel key distribution was fixed earlier. The channel key
2360 was used be to distributed to other routers as well which is not
2361 allowed by the protocol. Now this is fixed and channel keys
2362 really are cell specific and the channel message delivery between
2363 routers comply with the protocol specification.
2365 * Fixed various commands in server to check also the global list
2366 for the channel entry and not just the local list. The affected
2367 file silcd/command.c.
2369 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2371 * Added assert()s to buffer formatting and unformatting routines
2372 to assert (if --enable-debug) when error occurs. Affected
2373 file: lib/silcutil/silcbuffmt.c.
2375 * Changed to auto-reconnect to check whether the remote host is
2376 router and register the re-connect timeout if it is. It used
2377 to check that whether we are normal server, but router must do
2378 auto-reconnect with another router as well. Affected file
2381 * Removed the [<key len>] option from CMODE command as the cipher
2382 name decides the key length, nowadays. See the defined ciphers
2383 from the protocol specification.
2385 * Added [<hmac>] option to the CMODE command to define the HMAC
2386 for the channel. Added SILC_CMODE_HMAC channel mode.
2388 * Added [<hmac>] option for the JOIN command so that user can
2389 select which HMAC is used to compute the MACs of the channel
2392 * Added Hmac field to the Channel Message Payload. The integrity
2393 of plaintext channel messages are now protected by computing
2394 MAC of the message and attaching the MAC to the payload. The
2395 MAC is encrypted. Now, it is clear that this causes some
2396 overhead to the size of the packet but rationale for this is that
2397 now the receiver can verify whether the channel message decrypted
2398 correctly and also when private keys are set for the channel the
2399 receiver can decrypt the packet with several keys and check from
2400 the MAC which key decrypted the message correctly.
2402 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2403 lib/silccrypt/silccipher.[ch].
2405 * Added silc_hash_len to return the digest length into the
2406 lib/silcrypt/silchash.[ch].
2408 * Rewrote parts of Silc Channel Payload interface in the
2409 lib/silccore/silcchannel.[ch]. The encode function now also
2410 encrypts the packet and parse function decrypts it.
2412 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2414 * Fixed a minor formatting bug in the SKE's key material processing.
2415 It actually might have processed the keys wrong way resulting
2418 * Redefined the mandatory HMAC algorithms and added new algorithms.
2419 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2420 and hmac-md5 truncated to 96 bits. The mandatory is now
2421 hmac-sha1-96. Rest are optional (including the one that used
2422 to be mandatory). Rationale for this is that the truncated HMAC
2423 length is sufficient from security point of view and can actually
2424 make the attack against the HMAC harder. Also, the truncated
2425 HMAC causes less overhead to the packets. See the RFC2104 for
2428 * Added new [hmac] configuration section. The SKE used to use
2429 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2430 is of course wrong. The official names that must be proposed in
2431 the SKE are the ones defined in the protocol specification
2432 (hmac-sha1-96 for example). The user can configure any hmac
2433 using any hash function configured in the [hash] section. At
2434 least, the mandatory must be configured.
2436 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2438 * Added HMAC list to the SKE proposal list. It has now both
2439 hash algorithm list and HMAC list. This makes the protocol
2440 incompatible with previous versions. The SKE now seems to work
2441 the way it is supposed to work, for the first time actually.
2443 * Defined plain Hash algorithms to the protocol specification.
2446 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Implemented support for key agreement packets into the server.
2449 Added functions silc_server_key_agreement and
2450 silc_server_send_key_agreement. Other than these functions,
2451 server has nothing to do with this packet.
2453 * Added support for private message key packets into the server.
2454 Added functions silc_server_private_message_key and
2455 silc_server_send_private_message_key.
2459 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2460 called in the protocol's final callback instead in the END
2461 protocol state. This makes a little more sense and in the same
2462 time in client we can use the same protocol routines for normal
2463 key exchange and to key agreement packet handling as well.
2465 * Added to both client's and server's KE protocol context the
2466 SilcSKEKeyMaterial pointer to save the key material. We will
2467 bring the key material to the protocol's final callback by doing
2468 this. The final callback must free the key material.
2470 * Added SKE's packet_send callback into client's KE protocol
2471 context so that the caller can choose what packet sending function
2472 is used. This way we can use different packet sending when
2473 doing normal SKE when doing key agreement packet handling (in
2474 the key agreement packet handling we do not want to encrypt
2477 * Implemented the responder side of the key agreement routines
2478 in the client. The client can now bind to specified port and
2479 accept incoming key negotiation. The key material is passed
2480 to the application after the protocol is over.
2482 * Implemented the processing of incoming Key Agreement packet
2483 in the client. Added function silc_client_key_agreement to
2486 * Implemented the intiator side of the key agreement routines
2487 in the client. The client can now initiate key agreement with
2488 another remote client. The key material is passed to the
2489 application after the protocol is over.
2491 * Created client_keyagr.c to include all the key agreement
2494 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2495 SILC_TASK_CALLBACK except that it is not static.
2497 * Created client_notify.c and moved the Notify packet handling
2498 from the client.[ch] into that file.
2500 * Created client_prvmsg.c and moved all private message and
2501 private message key routines from the client.[ch] into that file.
2503 * Create client_channel.c and moved all channel message and
2504 channel private key routines from the client.[ch] into that file.
2506 * Changed silc_client_get_client_by_id_resolve to resolve with
2507 WHOIS command instead of IDENTIFY command, in the file
2508 lib/silclient/idlist.c.
2510 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2512 * Implemented the SKE's responder side to the Client library.
2514 * When FAILURE is received to the protocol do not trust it
2515 blindly. Register a timeout to wait whether the remote closes
2516 the connection as it should do it, only after that process the
2517 actual failure. This was changed to both client and server.
2519 * Added client_internal.h to include some of the structures
2520 there instead of client.h in lib/silcclient/.
2522 * Added function silc_task_unregister_by_callback to unregister
2523 timeouts by the callback function.
2525 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2527 * Some "Incomplete WHOIS info" errors has been appearing on the
2528 log files. Took away the entry->userinfo check from WHOIS
2529 reply sending. The entry->userinfo is now " " if client did not
2530 provide one. I thought this was fixed earlier but something
2531 is wrong still. Let's see if the error still appears.
2533 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2535 * Fixed a minor bug in the login when the channel key is
2536 re-generated in the server. It used to generate the key in
2537 wrong order and thus caused problems in the channel traffic.
2539 * Fixed a minor bug in channel key distsribution after
2540 KICK command. The key was not sent to the router even though
2543 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2545 * Added silc_ske_process_key_material_data as generic routine
2546 to process any key material as the SILC protocol dictates. The
2547 function is used by the actual SKE library but can be used by
2548 applications as well. This relates to the private message keys
2549 and the channel private keys since they must be processed the
2550 same way the normal SILC session keys. The protocol dictates
2551 this. Affected files: lib/silcske/silcske.[ch].
2553 Added also silc_ske_free_key_material to free the
2554 SilcSKEKeyMaterial structure.
2556 * Defined silc_cipher_set_key function to set the key for
2557 cipher without using the object's method function. The affected
2558 files: lib/silccrypt/silccipher.[ch].
2560 * Implemented silc silc_client_add_private_message_key,
2561 silc_client_add_private_message_key_ske,
2562 silc_client_del_private_message_key,
2563 silc_client_list_private_message_keys and
2564 silc_client_free_private_message_keys functions in the
2567 Added functions silc_client_send_private_message_key to send
2568 the Private Message Key payload and silc_client_private_message_key
2569 to handle incoming Private Message Key payload.
2571 * Added Cipher field to the Private Message Key payload to set
2572 the cipher to be used. If ignored, the default cipher defined
2573 in the SILC protocol (aes-256-cbc) is used.
2575 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Removed lib/silcclient/ops.h file.
2579 Redefined parts of the SILC Client Library API. Created new
2580 file silcapi.h that deprecates the ops.h file and defines the
2581 published Client Library API. Defined also private message key
2582 API and channel private key API into the file.
2584 This is the file that the application must include from the
2585 SILC Client Library. Other files need not be included by
2586 the application anymore.
2588 * Added new key_agreement client operation callback and also
2589 defined the Key Agreement library API for the application.
2591 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2594 is used by clients to request key negotiation between another
2595 client in the SILC network. If the negotiation is started it
2596 is performed using the SKE protocol. The result of the
2597 negotiation, the secret key material, can be used for example
2598 as private message key.
2600 Implemented the Key Agreement payload into the files
2601 lib/silccore/silauth.[ch].
2603 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Redefined ciphers for the SILC protocol. Added some new ciphers
2606 and defined the key lengths for the algorithms. Changed the
2607 code accordingly. The default key length is now 256 bits.
2609 * Fixed SKE key distribution function silc_ske_process_key_material
2610 when the key length is more than 128 bits. The default key
2611 length in SILC is now 256 bits.
2613 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2614 to indicate unsupported algorithm.
2616 * Renamed rijndael.c to aes.c and all functions as well.
2618 * Fixed a long standing channel key setting bug in client library.
2619 Weird that it has never surfaced before.
2621 * Fixed bug in channel deletion. If the entire channel is removed
2622 then it must also delete the references of the channel entry
2623 from the client's channel list as the client's channel entry and
2624 the channel's client entry share same memory.
2626 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2628 * Implemented CONNECT and SHUTDOWN commands in the client.
2630 * Implemented CLOSE command to the client.
2632 * Added the function silc_idlist_find_server_by_name into the
2633 files silcd/idlist.[ch].
2635 Added the function silc_idlist_find_server_by_conn into the
2636 files silcd/idlist.[ch].
2638 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2640 * DIE command was renamed to SHUTDOWN. Updated the both code
2643 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2644 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2646 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2649 * Added function silc_server_create_connection function to create
2650 connection to remote router. My server implementation actually
2651 does not allow router to connect to normal server (it expects
2652 that normal server always initiates the connection to the router)
2653 so the CONNECT command is only good for connecting to another
2656 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2659 or some other client was kicked from the channel.
2661 Implemented the handling of the notify type to both client
2664 Implemented silc_server_send_notify_kicked to send the KICKED
2665 notify. It is used to send it to the server's primary router.
2667 * Implemented the KICK command into server and client.
2669 * Added `query' argument to the silc_idlist_get_client function
2670 to indicate whether to query the client from server or not if
2673 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2674 to indicate that the client is not channel founder.
2678 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2680 * Removed the rng context from SilcPacketContext structure and
2681 changed that the packet routine uses the Global RNG API.
2683 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * Added support for quit message that client can "leave" on the
2686 channel when it quits the SILC. It is ditributed inside the
2687 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2689 Added silc_server_free_client_data that will take the
2690 signoff message as argument.
2692 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2694 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2696 * Updated parts of the protocol specification to keep it up
2699 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2701 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2702 payloads in one packet.
2704 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2705 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2706 use now the new List flag.
2708 * Also deprecated the following packet types: REPLACE_ID,
2709 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2711 * Added list support for Notify packet in server.
2713 * Added silc_server_send_notify_channel_change to send the
2714 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2715 the silc_server_send_replace_id.
2717 * Added silc_server_send_notify_nick_change to send the
2718 NICK_CHANGE notify type. Deprecates the function
2719 silc_server_send_replace_id.
2721 * Added silc_server_send_notify_join to send the JOIN notify type.
2722 Deprecates the function silc_server_send_new_channel_user.
2724 * Added silc_server_send_notify_leave to send LEAVE notify type.
2725 Deprecates the function silc_server_send_remove_channel_user.
2727 * Added silc_server_send_notify_cmode and
2728 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2729 types. Deprecates the silc_server_send_set_mode function.
2731 * Added SERVER_SIGNOFF notify type to indicate that server has
2732 quit. This means that all clients on the channel from that
2733 server will drop. This can be also used when netsplit happens.
2735 Deprecated REMOVE_ID packet type since it is not needed anymore
2738 Added silc_server_send_notify_server_signoff to send the
2739 SERVER_SIGNOFF notify type. Deprecates the function
2740 silc_server_send_remove_id.
2742 Added also silc_server_send_notify_signoff to send the
2743 SIGNOFF notify type.
2745 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2746 SILC protocol from this day on. Changed the protocol
2747 specification as well.
2749 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2750 notify type. It is used between routers to notify about
2751 topic changes on a channel.
2753 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2756 * Partly updated the protocol specification to comply with the
2757 changes now made. It is still though a bit outdated.
2759 * The JOIN notify type now takes one extra argument <Channel ID>.
2760 The packet used to be destined to the channel but now the
2761 JOIN type may be sent as list thus it is impossible to
2762 destine it to any specific channel. By adding this argument
2763 it is again possible.
2765 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2767 * Added CREDITS file. The CHANGES and CREDITS file will appear
2768 in the distribution as well.
2770 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2773 types in the server's silcd/packet_receive.c.
2775 * Implemented CMODE and CUMODE to work in router environment.
2777 * Fixed minor encoding and decoding buglet from the
2778 lib/silccore/silcmode.c.
2780 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2783 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2785 * Changed all SilcConfigServer* and silc_config_server* to
2786 SilcServerConfig* and silc_server_config*, respectively.
2789 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Associated the ID (client or server ID) to the Authentication
2792 Payload to avoid any possibility of forging. Updated the
2793 protocol specification and the code accordingly.
2795 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * The RSA key length is now save to the RsaKey context in the
2798 key generation process in lib/silccrypt/rsa.c. The key length
2799 is now used to figure out the maximum size of the block allowed
2800 to be encrypted/signed.
2802 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2803 is equivalent to the silc_mp_mp2bin but does not allocate any
2806 * Changed silc_mp_mp2bin API to take length argument. If it is
2807 non-zero then the buffer is allocated that large. If zero, then
2808 the size is approximated using silc_mp_sizeinbase, which however
2811 * Created Global RNG API which is global RNG that application can
2812 initialize. After initializing, any routine anywhere in the
2813 code (including library) can use RNG without allocating a new
2814 RNG object. This was done to allow this sort of use of the
2815 RNG in code that has no chance to allocate RNG object. All
2816 applications currently allocate this and many routines in the
2817 library use this. Affected file lib/silccrypt/silcrng.[ch].
2819 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2820 it to use the Global RNG API.
2822 * Defined Authentication Payload into protocol specification that
2823 is used during SILC session to authenticate entities. It is
2824 used for example by client to authenticate itself to the server
2825 to obtain server operator privileges.
2827 Implemented this payload into the lib/silccore/silcauth.[ch].
2828 Implemented also routines for public key based authentication
2829 as the new protocol specification dictates.
2831 Moved definitions of different authentication methods from
2832 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2834 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2835 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2836 silc_pkcs_verify_with_hash functions into the file
2837 lib/silccrypt/silcpkcs.[ch].
2839 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2841 * The client entry's userinfo pointer must be always valid.
2842 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2843 will fail since it requires the userinfo. Now, the userinfo
2844 is allocated as "" if actual userinfo does not exist. Actually,
2845 it must exist and it is totally Ok to drop client connections
2846 that does not announce the userinfo. However, we will make
2847 this workaround for now.
2849 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2850 to return the remote port by socket.
2852 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2855 SILC_SERVER_PENDING_EXEC and added an new macro
2856 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2857 data or when error occurs while processing the pending command.
2859 Added new argument `destructor' into silc_server_command_pending
2860 and to the SilcServerCommandPending object. This destructor is
2861 now called after calling the pending callback or if error occurs
2862 immediately. If error occurs the actual pending callback won't
2863 be called at all - only the destructor. The destructor may be
2864 NULL if destructor is not needed.
2866 All this applies for client library code as well. Similar
2867 changes were made there as well for the pending commands.
2869 In the client, the application must now allocate the
2870 SilcClientCommandContext with the silc_client_command_alloc
2873 * Added reference counter to the SilcServerCommandContext. Added
2874 function silc_server_command_alloc and silc_server_command_dup
2877 Same type of functions added to the client library for the same
2880 * Removed the cmd_ident from IDListData away since it is now
2881 global for all connections. It is the command identifier used
2882 in command sending and with pending commands. The affected file
2885 * Added reference counter to the SilcSocketConnection objecet to
2886 indicate the usage count of the object. The object won't be
2887 freed untill the reference counter hits zero. Currently only
2888 server uses this, and client ignores it. The client must be
2889 set to use this too later. The affected files are
2890 lib/silccore/silcsockconn.[ch]. Added also the function
2891 silc_socket_dup to increase the reference counter.
2893 This was mainly added because it is possible that the socket
2894 is removed underneath of pending command or other async
2895 operation. Now it won't be free'd and proper DISCONNECTING
2896 flags, etc. can be set to avoid sending data to connection that
2897 is not valid anymore.
2899 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2900 the connection. After that it sets SILC_SET_DISCONNECTED.
2901 It is, however, possible that the socket data is not still freed.
2902 The silc_server_packet_process now checks that data is not
2903 read or written to connection that is DISCONNECTED. The socket
2904 get's freed when the reference counter hits zero.
2906 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Changed the client operation API: channel_message operation's
2909 `sender' is now the client entry of the sender, not the nickname
2910 and the `channel' is the channel entry, not the channel name.
2912 In the private_message operation the `sender' is now also the
2913 client entry of the sender not the nickname.
2915 Affected file is lib/silcclient/ops.h and all applications
2916 using the client operations.
2918 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2920 * Moved the calling of ops->connect() from connect_to_server_final
2921 into receive_new_id functin since that is the point when the
2922 client is actually allowed to send traffic to network. The
2923 affected file is lib/silcclient/client.c.
2925 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2927 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2928 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2929 (if needs broadcasting) instead of broadcasting the packets one
2930 by one which would make a burst in the network traffic.
2932 * Added `broadcast' argument to the functions in silcd/server.[ch]
2933 silc_server_create_new_channel[_with_id] to indicate whether
2934 to send New Channel packet to primary router.
2936 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Added new function into the silcd/server.[ch] files:
2939 silc_server_create_new_channel_with_id to create new channel with
2940 already existing Channel ID.
2942 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2943 lib/silccore/silcpacket.h. This packet is used t send list of
2944 Set Mode payloads inside one packet. Server uses this to set
2945 the modes for the channels and clients on those channels, that it
2946 announced to the router when it connected to it. The protocol
2947 specification has been updated accordingly.
2949 * The silc_server_new_channel did not handle the packet coming
2950 from normal server as it normally does not send that. However,
2951 when it announces its channels it does send it. Implemented
2952 the support for that.
2954 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2955 into the file lib/silccore/id.h.
2957 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Fixed memory leaks in the functions silc_idlist_del_client,
2960 silc_idlist_del_channel and silc_idlist_del_server in the file
2961 silcd/idlist.c. All of those leaked like a sieve.
2963 * Fixed some small memory leaks in the client's function
2964 silc_client_notify_by_server.
2966 * Added functions into silcd/server.c: silc_server_announce_clients,
2967 silc_server_announce_channels and silc_server_announce_server.
2968 These functions are used by normal and router server to announce
2969 to its primary router about clients, channels and servers (when
2970 router) that we own. This is done after we've connected to the
2973 These functions effectively implements the following packet types:
2974 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2975 and SILC_PACKET_NEW_ID_LIST.
2977 * Added new functions into the silcd/packet_receive.[ch]:
2978 silc_server_new_id_list, silc_server_new_channel_list and
2979 silc_server_new_channel_user_list to handle the incoming
2980 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2982 * Added support of changing Channel ID in the function
2983 silc_server_replace_id. If the server that announces a channel
2984 to the router already exists in the router (with same name but
2985 with different Channel ID), router is responsible to send
2986 Replace ID packet to the server and force the server to change
2987 the Channel ID to the one router has.
2989 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2990 client that the Channel ID has been changed by the router. The
2991 normal server sends this to the client. Client must start using
2992 the new Channel ID as the channel's ID.
2994 Implemented handling of this new type into lib/silcclient/client.c
2995 into the function silc_client_notify_by_server.
2997 * Added new function silc_idlist_replace_channel_id into the files
2998 silcd/idlist.[ch] to replace the Channel ID.
3000 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * Call silc_server_command_identify_check always when processing
3003 the IDENTIFY command in silcd/command.c
3005 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3008 send keepalive packets. The packet can be sent by clients,
3009 servers and routers.
3011 Added function silc_socket_set_heartbeat into the file
3012 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3013 If not set, the heartbeat is not performed. The actual
3014 heartbeat is implemented in the low level socket connection
3015 library. However, application is responsible of actually
3018 Added silc_server_send_heartbeat to send the actual heartbeat
3019 packet into silcd/packet_send.[ch]. Server now performs
3020 keepalive with all connections.
3022 * Added silc_task_get_first function into lib/silcutil/silctask.c
3023 to return the timeout task with shortest timeout. There was a bug
3024 in task unregistration that caused problems. TODO has been
3025 updated to include that task system must be rewritten.
3027 * The client library will now resolve the client information when
3028 receiving JOIN notify from server for client that we know but
3029 have incomplete information.
3031 * Rewrote parts of silc_server_remove_from_channels and
3032 silc_server_remove_from_one_channel as they did not remove the
3033 channel in some circumstances even though they should've.
3035 * Encryption problem encountered in server:
3037 The LEAVE command used to send the Channel Key packet to the
3038 router immediately after generating it. However, the code
3039 had earlier sent Remove Channel user packet but not immediately,
3040 ie. it was put to queue. The order of packets in the router
3041 was that Channel Key packet was first and Remove Channel User
3042 packet was second, even though they were encrypted in the
3043 reverse order. For this reason, MAC check failed. Now, this
3044 is fixed by not sending the Channel Key packet immediately but
3045 putting it to queue. However, this is more fundamental problem:
3046 packets that are in queue should actually not be encrypted
3047 because packets that are sent immediately gets encrypted
3048 actually with wrong IV (and thus MAC check fails). So, packets
3049 that are in queue should be encrypted when they are sent to
3050 the wire and not when they put to the queue.
3052 However, the problem is that the current system has not been
3053 designed to work that way. Instead, the packet is encrypted
3054 as soon as possible and left to the queue. The queue is then
3055 just purged into wire. There won't be any fixes for this
3056 any time soon. So, the current semantic for packet sending
3059 o If you send packet to remote host and do not force the send
3060 (the packet will be in queue) then all subsequent packets to the
3061 same remote host must also be put to the queue. Only after the
3062 queue has been purged is it safe again to force the packet
3065 o If you send all packets immediately then it safe to send
3066 any of subsequent packets through the queue, however, after
3067 the first packet is put to queue then any subsequent packets
3068 must also be put to the queue.
3070 Follow these rules and everything works fine.
3072 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Added new function silc_server_remove_clients_by_server to
3075 remove all client entries from ID list when the server connection
3076 is lost. In this case it is also important to invalidate all
3077 client entires as they hold the invalid server entry. This
3078 fixes fatal bug when server has lost connection and will reconnect
3081 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Made some sanity checks to silc_server_daemonise like to check
3084 whether the requested user and group actually exists.
3086 * Added sanity check to SKE's silc_ske_responder_finish to check
3087 that the public and private key actually is valid.
3089 * Invalidate the client's nickname when receiving Replace ID
3090 packet and the Client ID is being replaced. This means that the
3091 server will query the nickname if someone needs it (client)
3094 * Sort the ID Cache in client library when the ID Cache data
3095 has changed (needs sorting).
3097 * Do not allow for SILC client to create several connections to
3098 several servers. The client does not support windows right now
3099 and generating multiple connections causes weird behaviour.
3101 Irssi-silc client does support windows and can handle several
3102 connections without problems, see: www.irssi.org and SILC plugin.
3104 * Fixed some places where client was added to the IDList. The
3105 rule of thumb is following (in order to get everything right):
3106 If the client is directly connected local client then the
3107 `connection' argument must be set and `router' argument must be
3108 NULL to silc_idlist_add_client function. If the client is not
3109 directly connected client then the `router' argument must
3110 bet set and the `connection' argument must be NULL to the
3111 silc_idlist_add_client function.
3113 * The funtion silc_server_packet_send_local_channel actually did
3114 not check whether the client was locally connected or not. It
3115 does that now. Fixed a bug related to LEAVE command.
3117 * Fixed Remove Channel User payload parsing bug in server's
3118 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3120 * The server's silc_server_save_channel_key now checks also the
3121 global ID list for the channel as it might not be in the local
3122 list. Fixed a bug related to LEAVE command.
3124 * Is this the end of the [<unknown>] buglet that has been lurking
3125 around for a long time? A little for loop fix in server's
3126 silc_server_command_whois_parse that is used by both IDENTIFY
3127 and WHOIS command. At least, this was a clear bug and a cause
3128 of one type of [<unknown>] buglet.
3130 * WHOIS and IDENTIFY commands call the function
3131 silc_server_command_[whois/identify]_check function even if
3132 we are not router server.
3134 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3136 * Added --with-gmp configuration option. If set the GMP
3137 is always compiled in the SILC source tree. If not set then
3138 it is checked whether the system has the GMP3 installed. If
3139 it has then the GMP won't be compiled (the system's headers
3140 and library is used), if it doesn't have it then the GMP is
3141 compiled in the SILC source tree.
3143 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Changed RSA private exponent generation to what PKCS #1
3146 suggests. We try to find the smallest possible d by doing
3147 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3148 not security fix but optimization.
3150 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Added new config entry [Identity] to fork the server and run
3153 it as specific user and group. A patch from Bostik.
3155 * Imported Dotconf configuration library into lib/dotconf.
3156 This will be used to create the SILC configuration files later.
3157 It will appear in the distsribution after this commit.
3159 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * A big code auditing weekend happening. Auditing code for
3162 obvious mistakes, bugs and errors. Also, removing any code
3165 Removed files for being obsolete:
3167 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3168 inline in the file lib/silcutil/silcbuffer.h)
3170 o lib/silcutil/silcbufutil.c (the header has inline versions)
3172 Changed code to fix possible error conditions:
3174 o The buffer formatting routines now check that the destination
3175 buffer really has enough space to add the data. This applies for
3176 both buffer formatting and unformatting
3177 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3178 unformatting was changed to accomodate following rules:
3179 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3180 sent to the function while XXX_*STRING will not allocate or copy
3181 the data into the buffer. Instead it sets the pointer from the
3182 buffer into the pointer sent as argument (XXX_*STRING used to
3183 require that the pointer must be allocated already). This change
3184 makes this whole thing a bit more consistent and more optimized
3185 (note that the data returned in the unformatting with XXX_*STRING
3186 must not be freed now). The routines return now -1 on error.
3188 o Tried to find all code that use buffer_format and buffer_unformat
3189 and added return value checking to prevent formatting and
3190 especially unformatting errors and possible subsequent fatal
3193 o Changed ske->x and ske->KEY to mallocated pointers in
3194 lib/silcske/silcske.h. Fixed possible data and memory leak.
3196 o Added return value checking to all *_parse* functions. Fixed
3197 many memory leaks as well.
3199 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3200 so that buffer overflows would not happen. All code now also
3201 checks the return value as it can fail.
3203 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * Added reconnection support to server if the normal server looses
3206 its connection to the router (for example if router is rebooted).
3207 The server performs normal reconnection strategy implemented
3208 to the server. Affected file silcd/server.c.
3210 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3212 * Added new packet type SILC_PACKET_SET_MODE that is used to
3213 distribute the information about changed modes (for clients,
3214 channels and clients channel modes) to all routers in the
3215 network. Updated the protocol specification accordingly.
3217 Added functions into silcd/packet_send.c and
3218 silcd/packet_receive.c: silc_server_send_set_mode,
3219 silc_server_set_mode.
3221 Added new files silcmode.[ch] into lib/silccore that implements
3222 the encoding and decoding of Set Mode Payload. Added new type
3223 SilcSetModePayload. Moved the definitions of different modes
3224 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3226 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Oops, a little mistake in server's connection authentication
3229 protocol. The protocol is not ended with FAILURE but with
3230 SUCCESS if the authentication is Ok. :) Affected file is
3233 * Implemented NICK_CHANGE notify handling in server in the file
3234 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3235 the local clients on the channel. After the changing nickname
3236 in router environment snhould work and the [<unknown>] nickname
3237 should appear no more.
3239 The silc_server_replace_id function that receives the Replace ID
3240 payload now sends the NICK_CHANGE notify type also in the file
3241 silcd/packet_receive.c
3243 * Changed WHOIS and IDENTIFY command to support the maximum amount
3244 of arguments defined in protocol specs (3328 arguments). This
3245 fixed a bug that caused problems when there were more than three
3248 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3250 * Added extra parameter, command identifier, to the
3251 silc_client_send_command so that explicit command identifier
3254 Changed that ID list routines uses specific command identifier
3255 when sending WHOIS/IDENTIFY requests to the server so that they
3256 can be identified when the reply comes back.
3258 Affected files lib/silcclient/command.[ch],
3259 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3261 * Added `sender' argument to silc_server_packet_send_to_channel
3262 to indicaet the sender who originally sent the packet to us
3263 that we are now re-sending. Ignored if NULL. Affected file
3264 silcd/packet_send.[ch].
3266 * Added some server statistics support in silcd/server_internal.h
3267 SilcServerStatistics structure and around the server code. Also
3268 send some nice statistics information when client is connecting
3271 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Fixed channel ID decoding in server's JOIN command reply in
3274 silcd/command_reply.c
3276 * Fixed braodcasting of replace ID payload to not to send it if
3277 we are standalone server in silcd/packet_receive.c.
3279 * Fixed all channel message sending routines to not to send
3280 packets to clients that has router set, since they are routed
3281 separately in the same function earlier. Affects file
3282 silcd/packet_send.c and all channel packet sending functions.
3284 * In USERS reply, res_argv[i] are not allocated, the table
3285 is allocated. Thus changed that free the table, not its
3288 * In server's whois_check and identify_check if the client is
3289 locally connected do not send any WHOIS commands - they are not
3292 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Fixed some minor bugs in client when sending WHOIS command. The
3295 arguments was in wrong order.
3297 * Removed statis function add_to_channel from server in
3298 silcd/command.c that was previously used with the joining but
3301 * Tested USERS command in router environment successfully with two
3302 routers, two servers and two clients.
3304 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Reorganized the USERS command and command reply in client library
3307 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3308 When the command is given by user we register a pending command
3309 callback that will reprocess the command after the reply has been
3310 received from the server. When reprocessing the packet we then
3311 display the information. Thus, the USERS information is displayed
3312 now in the command callback instead of in the command reply
3313 callback. The processing of the command is same as previously
3314 when server has sent the command reply in the JOINing process.
3316 * Added to USERS command in silcd/command_reply.c to join the client,
3317 we didn't use to know about, to the channel after we've created
3318 a client entry for it. Also, for clienet we did know already still
3319 check whether it is on the channel or not and add it if not.
3321 * Removed silc_server_command_join_notify as the function and its
3324 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Changed the client's pending command handling to the same as the
3327 server's pending command handling. It is also now possible to
3328 execute command reply functions from other command reply
3329 function as the function callbacks for commands and command
3330 replies are one and same. The pending commands are not static
3331 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3332 in client connection context. Thus, pending commands are server
3333 connection specific as it is convenient.
3335 Changed the function silc_client_command_pending and
3336 silc_client_command_pending_del and added new function
3337 silc_client_command_pending_check. Removed the
3338 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3341 * Added cmd_ident, current command identifier, to the client
3342 connection context in lib/silcclient/client.h to keep track on
3343 command identifiers used in command sending. Client's command reply
3344 function handling now supports the mandatory command identifiers.
3346 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3347 funtions in client to fully support pending command callbacks.
3349 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3350 as one of the arguments to the application in the command reply
3353 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3354 before first releasing SILC but came back. Now it is removed again
3355 and should come back nomore. The FORWARDED flag was used only
3356 by the JOINing procedure by forwarding the command packet to router.
3357 Now, the JOINing procedure has been changed to more generic (due
3358 to various router environment issues) and FORWARDED is not needed
3359 anymore for anything. The protocol specification is yet to be
3362 Now, removed silc_server_packet_forward from server and the flag
3363 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3365 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Renamed NAMES command to USERS command. The NAMES was named that
3368 due to historical reasons. Now it is renamed. Also, rewrote
3369 parts of the USERS command. The nickname list is not sent anymore
3370 by the server. Only Client ID and mode lists are sent in the USERS
3371 command. Changed this also to the protocol specification.
3373 The client now resolves the names and stuff after it receives
3374 the USERS list from the server when joining to the channel.
3376 * WHOIS and IDENTIFY commands has been changed to support multiple
3377 Client ID's per command. One can now search for multiple users
3378 in the network by sending only one WHOIS or IDENTIFY command.
3379 Changed the code and the protocol specifications.
3381 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3382 uses silc_server_command_whois_parse to parse the request. */
3384 * If normal server, do not parse the WHOIS and IDENTIFY requests
3385 before sending it to the router. Saves some time.
3387 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3389 * Fixed JOIN command on client library. Wrong number of arguments
3390 used to crash the client.
3392 * Added silc_server_channel_has_global function to check whether
3393 channel has global users or not.
3395 * Added silc_server_channel_has_local function to check whether channel
3396 has locally connected clients on the channel.
3398 * The silc_server_remove_from_one_channel now checks whether the
3399 channel has global users or not after given client was removed from
3400 the channel. It also checks whether the channel has local clients
3401 on the channel anymore. If it does not have then the channel entry
3402 is removed as it is not needed anymore.
3404 * The silc_server_notify now checks on JOIN notify whether the joining
3405 client is one of locally connected or global. If it is global then
3406 the channel has now global users on the channel and that is marked
3407 to the channel entry. Also, it now saves the global client to
3408 global list who is joining and JOINs it to the channel. This is
3409 for normal server, that is.
3411 Changed silc_server_send_notify_on_channel,
3412 silc_server_packet_relay_to_channel and
3413 silc_server_packet_send_to_channel check if we are normal server
3414 and client has router set (ie. global client) do not send the
3415 message to that client, as it is already routed to our router.
3417 * Implemented LEAVE notify type handling in silc_server_notify
3420 * Tested LEAVE command in router environment successfully. Tested
3421 with two routers, two servers and two clients.
3425 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3427 * Implemented SIGNOFF notify type handling in silc_server_notify
3430 * silc_server_remove_id now removes the client entry from all channels
3431 it has joined and thusly sends SIGNOFF notify type.
3433 * Rewrote the NAMES list generation in server by removing two excess
3434 loops. The lists are created now inside one loop.
3436 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * silc_server_remove_channel_user checks now also global list
3439 for channel and client.
3441 * silc_server_new_channel_user checks now both local and global
3442 list for channel and client. Fixed a bug in client id decoding.
3443 Used to decode wrong buffer.
3445 * silc_server_channel_message checks now both local and global
3446 list for channel entry.
3448 * Tested channel joining (hence JOIN) in router environment
3449 successfully. Tested with two routers, two servers and two
3452 * Tested channel message sending in router environment successfully.
3454 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3456 * Added silc_server_save_channel_key into server.[ch] to save the
3457 received channel key in Channel Key payload processing. It is
3458 also used in JOIN command reply handling.
3460 Equivalent function silc_client_save_channel_key added into
3461 client.[ch] into client library.
3463 * Changed JOIN command reply to send information whether the channel
3464 was created or not (is existing already) and the channel key
3465 payload. Changed protocol specs accordingly.
3467 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3468 the request was sent by ID and not by nickname. Crashed on
3471 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3473 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3474 now correctly save the received data.
3476 * silc_server_free_sock_user_data now notifies routers in the
3477 network about entities leaving the network.
3479 At the same time implemented functions silc_server_remove_id
3480 and silc_server_send_remove_id to receive and send REMOVE_ID
3481 packets. The packet is used to notify routers in the network
3482 about leaving entities. The ID removed will become invalid in
3485 * Added function silc_idlist_del_server into server. Removes and
3486 free's server entry from ID list.
3488 * silc_server_private_message function now checks, if we are router,
3489 that the destination ID really is valid ID, naturally.
3491 * In router when NEW_ID packet is received (for new client) the
3492 hash of the Client ID is saved in the ID Cache but the
3493 client->nickname is set to NULL, instead of putting the hash
3496 IDENTIFY command now also checks that client->nickname must be
3497 valid. If it is not if will request the data from the server who
3498 owns the client. Added new function
3499 silc_server_command_identify_check.
3501 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3502 to set the command to already allocated Command Payload.
3504 * Tested private message sending in router environment with two
3505 routers, two servers and two clients. Fixed minor bugs and now
3508 * Fixed segfault from client's NAMES command. Used to crash if
3511 * Forwarded packets must not be routed even if it is not destined
3512 to the receiver. Changed server code comply with this.
3514 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Added `require_reverse_mapping' boolean value to ServerParams
3517 structure. If TRUE (not default) the server will require that
3518 the connecting host has fully qualified domain name.
3520 If the reverse mapping is not required and hostname could not be
3521 found the IP address is used as hostname.
3523 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3525 * Implemented version string checking to both client and server.
3526 The check is incomplete currently due to the abnormal version
3527 strings used in development version of SILC.
3529 * Changed all command functions in server to use the new
3532 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Changed char *data to unsigned char *data in ID Cache system to
3535 support binary data as ID Cache data. Changed code to support
3536 binary data in lib/silccore/idcache.c.
3538 * Renamed silc_server_packet_relay_command_reply to
3539 silc_server_command_reply as it is normal packet receiving
3540 function. Rewrote the function to accept command replys for
3541 servers and not only for clients.
3543 * Mark remote router always as registered server if we are connecting
3544 to it. Otherwise, commands sent by the router to us are ignored.
3546 * All ID List find routines now returns the ID Cache Entry pointer
3547 as well if requested.
3549 * WHOIS command works now in router environment, tested with two
3550 routers, two servers and two clients.
3552 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3553 in router environment (as it is almost equivalent to WHOIS) but
3554 hasn't been tested thoroughly. Added new functions:
3556 silc_server_command_identify_parse
3557 silc_server_command_identify_send_reply
3558 silc_server_command_identify_from_client
3559 silc_server_command_identify_from_server
3561 * Disabled route cache adding because adding two different ID's with
3562 same IP replaces the old cache entry thus giving wrong route.
3563 The entry->router->connection is always the fastest route anyway
3564 so route cache may not be needed. Of course, new routes maybe
3565 established after receiving the ID when the entry->router->connection
3566 might not be anymore the most optimal.
3568 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Add route cache for received ID for fast routing.
3572 * Added silc_server_packet_route to route received packet on router
3573 that is not destined to us.
3575 * Renamed silc_server_get_route to silc_server_route_get.
3577 * Added id_string and id_string_len fields into SilcServer to
3578 include encoded ServerID for fast comparing without excess
3579 encoding of the ID's.
3581 * Cleaned up WHOIS command on server side. Added following static
3584 silc_server_command_whois_parse
3585 silc_server_command_whois_check
3586 silc_server_command_whois_send_reply
3587 silc_server_command_whois_from_client
3588 silc_server_command_whois_from_server
3590 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3591 arguments in command replies. All command functions should be
3592 updated to use this macro.
3594 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3596 * Minor typo fixes on command reply handling on server.
3598 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Added silc_server_command_add_to_channel internal routine to add
3601 the client to the channel after router has created the channel and
3602 sent command reply to the server.
3604 * Added generic silc_server_send_command to send any command from
3607 * Use static buffer with ID rendering instead of duplicating data.
3609 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * Fixed a channel user mode bug when joining to a channel server gave
3612 everybody channel founder rights, oops.
3614 * We mark ourselves as the router of the incoming server connection
3615 if we are router ourselves. This way we can check in some packet
3616 sending functions whether it is locally connected server. For
3617 incoming router connections we put NULL.
3619 * For router sending packets locally means now always sending the
3620 packet cell wide; to local clients and local servers. For normal
3621 server sending packet locally means sending it to only local
3624 * Fixed the JOIN command to really work in router environment. If the
3625 channel is created it is always created by the router. Router is
3626 also responsible of making the initial joining to the channel,
3627 sending JOIN notify to the sending server and distributing
3628 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3629 does not exist server doesn't do anything else but forward the
3630 command to the router which performs everything.
3632 * Added silc_server_send_channel_key function to send the Channel Key
3635 * Added silc_server_create_channel_key to create new channel key. The
3636 channel key is now re-generated everytime someone joins or leaves
3637 a channel, as protocol dictates. Note: channel->key_len is the
3640 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3643 packet_receive.[ch] to separate packet sending and receiving
3644 routines. The server.[ch] now includes everything else including
3645 actual packet processing (writing and reading data) and other
3648 Renamed silc_server_private_message_send_internal to
3649 silc_server_send_private_message. The routine is still though
3650 used only to relay private messages as server does not send
3651 private messages itself.
3653 Renamed silc_server_new_channel to silc_server_create_new_channel
3654 and added new function sicl_server_new_channel that handles the
3655 incoming New Channel packet. Added also new sending function
3656 silc_server_send_new_channel to send New Channel Payload.
3658 * Added new function silc_server_notify to process incoming notify
3659 packet to the server/router. Server may then relay the notify
3660 to clients if needed.
3662 * Added new function silc_server_new_channel_user to process incoming
3663 New Channel User packet. Router will redistribute the packet and
3664 send JOIN notify to its local clients and locally connected servers
3665 if needed. Normal server will send JOIN notify to its local client
3666 on same channel when received this packet. Added also corresponding
3667 sending function silc_server_send_new_channel_user to sent the
3670 * Added boolean route argument to send_notif_to_channel and
3671 packet_send_to_channel functions to attempt to route the packet
3672 if it is TRUE and send only locally if it is FALSE.
3674 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * silc_server_replace_id now broadcasts the received replace ID
3677 packet if it is not broadcast packet already. The router must
3678 broadcast to inform other routers about changed ID.
3680 * Added backpointer to server's router into SilcServer context in
3681 silcd/server_internal.h.
3683 * Fixed silc_server_packet_broadcast to send correct broadcast
3686 * The channel key is now distributed to the local client as soon
3687 as it is received from the router (in router environment) so that
3688 no other packet may be sent for the channel until client has
3691 * silc_server_remove_channel_user now broadcasts the received
3692 Remove Channel User packet if it is not broadcast packet already.
3693 The router must broadcast to inform other routers about removed
3696 * Added users field into SilcPacketContext that is a reference count
3697 of the context. One can increase the reference count by calling
3698 silc_packet_context_dup which is now changed to just increase the
3699 reference count instead of duplicating the data. The reference
3700 count is decresed by calling silc_packet_context_free that will
3701 free the data after the reference count hits zero.
3703 For now on the packet context and everything allocated into it
3704 (including the raw packet from network) must be freed by calling
3705 the new silc_packet_context_free function. Added also new function
3706 silc_packet_context_alloc that must be used now to allocate the
3707 context. This also means that if a routine is asynchronous from
3708 silc_[client/server]_packet_parse_type the packet context must
3709 be duplicated by calling silc_packet_context_dup. Otherwise it
3710 gets free'd after silc_[client/server]_packet_parse_type returns.
3711 Also, one must remember that if packet is duplicated then its
3712 reference count must be decresed by calling the free function as
3713 many times as it was duplicated.
3715 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3716 from both client and server.
3718 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Made joining to a channel working in router environment.
3722 * Cleaned up JOIN command on server side and create function
3723 silc_server_command_join_channel internal routine to make the
3726 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * Changed silc_command_pending list to SilcDList. Also, added
3729 `ident' field to SilcServerCommandPending structure to identify
3730 the reply and to call correct callback.
3732 Added silc_server_command_pending_check function to replace the
3733 corresnponding macro. The silc_command_pending list is not
3736 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3737 to set identifier to previously allocated Command Payload. It
3738 is used to set identifier for command when resending Command
3741 * Added silc_command_payload_encode_payload to encode Command
3742 Payload buffer from SilcCommandPayload structure.
3744 * Added silc_argument_payload_encode_payload to encode Argument
3745 payload buffer from SilcArgumentPayload structure.
3747 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Changed WHOIS command to support router connection on server side.
3750 The whois request is always sent to router unless the server is
3751 standalone server. After server has received the reply from the
3752 router will it send the reply to the client.
3754 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3755 broadcast received broadcast packet. The function is used only
3756 by router. The broadcast packet is always sent to the router's
3759 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3760 render given ID to printable string, for log files for example.
3762 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Made basic router to router connections working. At least they
3765 can now connect to each other but nothing really works the way
3766 they are supposed - yet.
3768 * Added new initiator token to RouterConnection configuration
3769 file in silcd/serverconfig.[ch]. It is used to tell whether we
3770 are the initiator to the remote router or whether we'll expect
3771 the other end to connect.
3773 * Moved registering of listener task to silc_server_init, hence
3774 the server starts listenning as soon as it is run, even if it
3775 does not have connections to other routers. Let's see how well
3778 * Changed default connection retry timeouts for more suitable in
3781 * Removed cipher and such arguments from silc_idlist_add_client
3782 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3783 Added new function silc_idlist_add_data to add the keys and stuff
3786 * Added SilcIDListData structure and added it to SilcClientEntry
3787 and SilcServerEntry as their first field in the structure. This
3788 way we can explicitly cast the ID entries to the SilcIDListData
3789 structure and get common data for the entries. In past, we had
3790 to first check what type of connection it is and then cast it to
3791 correct ID entry type. Now, we can directly cast the opaque
3792 pointer to the SilcIDListData (no matter what ID entry it actually
3793 is) and get the data needed.
3795 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3798 in some circumstances even if threre were timeout tasks, though not
3799 IO tasks, but tasks anyway. Now fixed.
3801 * Defined SilcServerConnection structure to hold connection specific
3802 stuff about directly connected servers and routers. The definition
3803 is currently in silcd/server_internal.h. I thought about having
3804 a bit more important role fro this struct but for now it is used
3805 only when connecting to other server (or router actually).
3807 * Added connecting retry support in server when connecting to
3808 router(s). The retry feature implement exponential backoff
3809 algorithm. Also, added SilcServerParams structure to hold default
3810 parameters for server. For now, it include these retry settings
3811 and are hard coded. After server is moded to be as Silc Server
3812 Library this structure will be more important.
3814 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3816 * Changed client librarys channel->clients table to SilcList and
3817 changed code accordingly.
3819 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Changed client's channel table to SilcList and changed code
3822 accordingly. Also changed SilcChannelClientEntry to include back-
3823 pointer to the channel so that client entry can use that structure
3824 as list as well and we have fast cross-reference to the channel.
3825 This change dramatically decreased the complexity of channel
3826 handling with client entry and vice versa (removed one extra
3827 loop when searching for channel entry from many functions).
3829 * Changed server->sim from table to SilcDList and changed code
3832 * NAMES command can now be used from user interface. It will show
3833 the user list on the channel, neatly.
3835 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3836 Code now saves realname of the user if it becomes available.
3838 * Renamed configure.in to configure.in.pre and made ./prepare
3839 script to automatically add correct version string to
3840 configure.in which it creates from configure.in.pre.
3842 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * NAMES command reply now shows users mode with the nickname when
3847 * Moved silc_client_ch[u]mode[_char] functions from
3848 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3849 place sucks, they are utility functions and should be in some
3852 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3854 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3857 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Added TRQ (efficient deque and list library) into lib/trq. This is
3862 a very good list library that is currently used in the SILC. Defined
3863 SilcList API over the library because I didn't like the API very
3864 much. See lib/trq/silclist.h for the API and examples of how to
3865 use the API. Fixed various places in the code to use the new
3866 SilcList API. The SilcList is meant for lists that has a structure
3867 already defined as a list. It is not suitable to add just some
3868 context to the list (in TRQ, the context is the list actually).
3870 So, I defined SilcDList that can be used for the purpose where
3871 predefined list structure does not exit. This can be used as
3872 such list. Now some context just can be added to the SilcDList.
3873 Currently this list is not used in the SILC just yet, though there
3874 are a lot places where this can replace dynamically allocated
3875 tables and I will fix these places, later, to use SilcDList.
3876 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3877 and use TRQ internally).
3879 Also fixed some annoying warning messages that the original TRQ
3880 code generated. Also minor changes to TRQ's Makefile.in.
3882 * Added support for querying by Client ID to both WHOIS and
3883 IDENTIFY commands into server, as required by the protocol.
3885 * Removed method function pointers from SilcBuffer structure. They
3886 weren't used to anything and just increased the context size for
3887 no good reason. This change also made silc_buffer_alloc and
3888 silc_buffer_free functions inline functions.
3890 * Disabled command flooding detection support until it's fixed so
3891 that it accepts commands in but does not execute them more than once
3894 * Added silc_net_localhost(), to return local hostname, into
3895 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3896 that must be initialized before calling silc_client_init.
3898 * Added new function: silc_server_send_notify_on_channels to send
3899 notify messages to all channels client has joined. It is assured
3900 that the message is sent only once per client.
3902 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3903 lib/silcutil/silcutil.[ch] as silc_format function. The new
3904 function is generic and is used by server as well, not only by
3905 the logging routines.
3907 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3908 the provided version string was not acceptable. Added new function:
3909 silc_ske_check_version into lib/silcske/silcske.h. The function
3910 must be implemented by the application (client or server) and it
3911 does not reside in the SKE library. The function checks the version
3912 string remote end sent.
3914 * Added back pointers (to opaque context and to SilcSocketConnection)
3915 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3917 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3918 duplicate packet context structure.
3920 * Changed `notify' client operation to send same arguments as client
3921 receives from server except for ID's. ID's are mapped to correct
3922 ID entry and that is returned. Also, if channel entry is not sent
3923 by server but the notify is for channel the channel entry is sent
3924 to application (otherwise application doesn't know that it is for
3925 channel (library gets it from packet's Destination ID)).
3927 * Added silc_client_remove_from_channels into client library to
3928 remove a client from all channels it has joined to. Used when
3929 received SIGNOFF notify from server. Added also new function
3930 silc_client_replace_from_channels to replace old ID entry with
3931 new ID entry on all channels. Used when received NICK_CHANGE
3934 * Fixed ID Cache list handling in silc_idlist_get_client in
3935 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3936 to get (or query) client by ID.
3938 * Updated TODO list.
3940 * Added connection authentication status message defined by the
3941 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3942 support for these into the code in client and server side.
3944 * Added generic function silc_client_send_command to send any command
3945 with variable argument list. Application should use this function
3946 to send commands if the command functions provided by the library
3947 does not suite for the application's user interface needs.
3949 * Added new `failure' client operation. Application is notified about
3950 received failure packet if client is executing a protocol. In this
3951 case the protocol's execution has failed.
3953 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3954 is required by the protocol.
3956 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3957 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3960 * Added status flag to SilcSKE object to indicate realtime status
3961 of the SKE protocol.
3963 * Application receives now exactly same command reply arguments as
3964 the library receives from server. However, if ID is received the
3965 corresponding ID entry is returned to the application (eg. Client
3966 ID is mapped to correct SilcClientEntry entry and that is returned).
3967 Changed command_reply client operation due to this change.
3969 * Changed all ID's in commands and in command replys as ID Payloads.
3970 Change affected both client and server side codes.
3972 All ID's sent in SILC network (with execption of ID's in SILC
3973 Packet header) are sent in ID Payload to support variable length
3976 * Server now notifies nick changes and notifies all clients on
3977 the channels about the new nickname (about the new Client ID,
3980 * Implemented CMODE command to change channel modes. Supports all
3981 channel modes defined by the protocol specs except ban and invite
3982 lists. (Also, private channel key mode is supported but support for
3983 setting private channel key in client is missing, thus, this mode
3984 has no effect on client side (except that server requires that the
3985 client uses private channel key and normal channel traffic does not
3988 Also, invite mode works per se, but INVITE command does not work
3989 yet correctly, so you can set channel as invite only channel but
3990 inviting clients to the channel does not work (it is yet to be
3991 thought what's the best way to do it).
3993 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3994 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3995 Implemented CUMODE command to change user's mode on the channel.
3996 Supports all modes defined by the protocol specs.
3998 * Added NAMES command reply to return users modes on the channel.
4000 * Removed unnecessary and slow ciphers from lib/silccrypt.
4002 * Set SO_KEEPALIVE option to connection sockets by default.
4004 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4006 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4007 redefined the Notify Payload into protocol specs.
4009 * Added silc_id_payload_parse_id to get ID directly from raw
4012 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4015 accept searching by Client ID as well.
4017 * Added support for LEAVE and SIGNOFF notify types in client library.
4019 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4020 to parse ID Payload from raw data.
4022 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Added flags parameter into silc_ske_assemble_security_properties
4025 function in lib/silcske/silcske.[ch].
4027 * Changed notify client operation to fit better for notify messages
4028 sent by server. The notify payload received from server is now
4029 passed to the application (after parsing it to SilcNotifyPayload).
4030 It is application's responsibility to retrieve the arguments
4031 from the payload and show the message the way it wants. The message
4032 sent by server is implementation specific.
4034 * Changed public keys to comply with the protocol specification.
4035 Old public keys are not supported anymore and are not compatible.
4037 * Removed nickname from Channel Payload as the latest draft removed
4038 it. The client must resolve the nickname from the NAMES command
4039 reply received when it joined the channel.
4041 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4043 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4045 * Fixed some errors in protocol specification drafts.
4047 * Created lib/silccore/silcnotify.c to implement Notify Payload
4048 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4049 generic payloads described by protocol specifications. The file
4050 includes implementations for ID Payload and Argument Payload.
4052 * Changed Command Payload implementation to use the new Argument
4053 Payload. Changed command_xxxx_payload to command_payload_xxxx
4054 to comply with SILC coding conventions.
4056 * Added suppport for Argument Payload handling in Notify Payload
4057 implementation as protocol requires it. Added the new support
4058 into server and client lib as well.
4060 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Added support for multiple nicknames on same channel. [n] is
4063 added locally to the nickname if there are more than one same
4064 nicknames on the channel.
4066 * Server now sends all nicknames that matched WHOIS request.
4067 Client also shows the list received from server.
4069 * Added TOPIC command to client side. User can now set and show
4070 current topic on channel.
4072 * Added MOTD command to client and server. Also, server sends the
4073 motd when client connects to the server.
4075 * Changed version strings to comply ISO 8601.
4077 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Fixed protocol error handling in client library. It should now
4080 cope even if the SKE fails for some reason.
4082 * Made new protocol specification drafts for submitting to IETF.
4084 * Implemented TOPIC command to server in silcd/command.c.
4086 * Added two new notify types into lib/silccore/silcnotify.h:
4087 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4088 notify nickname change and topic setting/change on a channel.
4090 * API change of command_reply operation in client library. The
4091 application gets now the status type received from server as well.
4093 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4095 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4097 * Cras fixed and optimized the packet handling even further and
4098 it should work now. Minor change to the prototype of function
4099 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4101 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Added new function into lib/silcutil/silcschedule.[ch]:
4104 silc_schedule_with_fd to select() a specified fd. The function
4105 returns after timeout expires or data arrives or goes. The
4106 function is used by packet routines to wait that all data is
4107 received from network.
4109 * Fixed data reading from network in lib/silccore/silcpacket.c.
4110 The code now assures that all data is read from the fd and then
4111 continues packet processing. This was a bug fix since the code
4112 used to drop some data in some circumstances.
4114 * Added new function into lib/silcclient/client.[ch]:
4115 silc_client_start_key_exchange to start key exchange after
4116 connection has been established to server. The code internally
4117 now uses this funtion but its main purpose was to provide it
4118 for applications that perform their own connecting. After
4119 application has created a connection it merely calls this
4120 function to start the key exchange between client and server.
4121 The library takes care of everything else after that.
4123 Updated also lib/silcclient/README to explain the usage of
4126 * Do not send to application information that connection has
4127 been established. Application gets notified it by connect
4130 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Applied cras's patch to add silc_schedule_one function. The
4133 function runs scheduler once and returns.
4135 * Fixed the scheduler after cras messed it up. The timeout
4136 handling works now as it's supposed to work.
4138 * Added into lib/silccore/ silcnotify.h to include notify
4139 message types support. Changed silc_server_send_notify*
4140 functions, in server.[ch], to support those new notify types.
4141 Added the support for the notify types into client library,
4142 as well. Added new notify client operation into ops.h in
4145 * Changed silc_server_packet_send_to_channel to send normal
4146 packets instead of just channel message packets. The function
4147 is now used to send the notify packets to channels. It is not
4148 used to send channel message packets anymore, as server never
4151 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4152 va_arg()s as it seems to require it nowadays. I guess, if SILC
4153 is compiled with older va_arg() the new code should work anyway.
4155 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Splitted core library. Core library (lib/silccore) includes
4158 now only SILC protocol specific core (and common) components.
4159 Created new utility library (lib/silcutil) that includes more
4160 generic purpose stuff. The stuff for util library was taken
4161 from the old core library. This was minor and easy split.
4163 * Created SILC Client Library (lib/silcclient) that includes
4164 implementation of the SILC client without user interface. This
4165 was major move from silc/ directory. The code has been changed
4166 so that it is transparent towards the user interface. The
4167 silc/ directory includes now the same user interface as before
4168 and it uses the new client library. Read lib/silcclient/README.
4169 Basicly, the client library performs everything else related
4170 to SILC except user interface handling. Also, configuration
4171 files are considered to be part of user interface and library
4172 does not handle them.
4174 This change also changed a lot of structures, function naming etc.
4175 Most important change was that SilcClientWindow object was
4176 renamed to SilcClientConnection in the client library. Created
4177 also new file lib/silcclient/ops.h. Also added new files
4178 silc/local_command.[ch] and silc/client_ops.[ch].
4180 All these changes were made to make it easier for user interface
4181 designers to create what ever user interface for the SILC client
4184 It is also expected that the server will be moved to lib
4185 directory as well and SILC Server Library will be created;
4186 sometimes in the future.
4188 * Removed Local commands from lib/silccore/silccommand.h as
4189 they are application specific and new client library does not
4190 handle any of those anymore.
4192 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4193 old client implementation in silc/.
4195 * Added support for callback functions in SILC_LOG_* macros.
4196 Application can now set its own callbacks that will be called
4197 instead of using the default functions that will always print
4198 the debug messages to stderr (or stdout). Also, debugging can
4199 now be disabled by setting silc_debug to FALSE and re-enabled by
4200 setting it to TRUE. Note, that logging will still work even
4201 if debugging is disabled.
4203 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4204 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4205 silc_log_reset_debug_callbacks.
4207 * To enable debugging in silc client one must give now -d
4208 option on command line.
4210 * Changed silc_schedule_init to automatically allocate task queues
4211 if they are not allocated before calling it.
4213 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Added GMP 3.1 into math library.
4217 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4219 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4220 a channel in SILC network. The packet is used by servers and
4221 routers to notify other routers that user has left a channel.
4222 This little feature was missing until now. Added the feature
4223 to protocol specification as well.
4225 Added functions: silc_server_send_remove_channel_user and
4226 silc_server_remove_channel_user into server.[ch].
4228 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4229 lib/silccore/silcpacket.h. However, they are not implemented
4232 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Fixed joining to a channel and sending channel messages
4235 between server and router. The channel message sending should
4236 now work inside a cell.
4238 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * Fixed the private message sending between server and router.
4241 The private message sending should now work inside a cell.
4243 * Added silc_server_replace_id into server.[ch] to replace
4244 existing ID in the SILC network.
4246 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4247 and silc_idlist_replace_server_id into idlist.[ch] in server.
4249 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Fixed the server to server connections. Server can again now
4252 connect to router. Router to router connections probably does
4255 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Added dynamic protocol registering support. Now protocols can
4258 registered and unregistered on the fly. Patch by cras.
4260 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Added lib/contrib directory to hold routines that some platforms
4263 don't have but are needed by SILC.
4265 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4266 into lin/contrib to provide getopt() and getopt_long() for
4267 those who don't have it.
4269 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Added AWAY command to client. When away message is set and
4272 client receives a private message packet the client automatically
4273 replies to the sender with the away message.
4275 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4276 bug seemed to be the cause of recent problems when compiling
4279 * Added version detection support to SKE protocol specification
4280 and added the new changes to the SKE implementation as well.
4281 There were other minor changes in the SKE protocol as well.
4283 Many changes in lib/silcske/silcske.[ch] and in
4284 lib/silcske/payload.[ch].
4286 * Added ^U functionality, clear input line. Patch from cras.
4288 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Mainly small bugfixes on core library. Fixed some debugging
4291 logging and buffer overflow in silclog.c.
4293 * Updated config.sub and config.guess on the distribution tree.
4295 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4297 * Added command lagging support in server. Client may execute
4298 commands now only once in two seconds.
4300 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Optimized packet reception. MAC computation and checking is now
4303 also more optimized. A lot previously duplicated code is now
4304 used as generic by both client and server.
4306 * Fixed key pair generation in clientutil.c
4308 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Added into lib/silccore/silcbufutil.[ch] new function;
4311 silc_buffer_realloc.
4313 * Moved generic packet sending/encryption functions to
4314 lib/silccore/silcpacket.[ch] from client and server. Some
4315 rewriting of the functions.
4317 * Moved all generic packet reception/decryption functions to
4318 lib/silccore/silcpacket.[ch] from client and server. The
4319 packet processing is now much cleaner in both client and server.
4320 These were major changes in both client and server.
4322 * Created many common functions in server to do packet sending.
4323 Previously code were duplicated a lot, this has been removed
4326 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Rewrote major parts of the ID cache system. Don't know
4329 whether it is better now or not but at least the API is more
4332 * Major rewrite on ID cache stuff on client because of the ID
4333 cache API changes. Added idlist.c to client.
4335 * Also major rewrite on ID cache stuff on server as well.
4336 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4337 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4338 in hand, instead they are all put into the ID cache system now.
4339 All server_idlist_* routines uses ID cache now instead of
4340 traversing its own lists (those lists does not exist anymore).
4341 SilcIDList though still exists. Also, SilcXXXEntry's are
4344 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Finally made the SKE implementation compliant to the protocol
4347 specification. All mp integers are now binary encoded as
4348 opposed being HEX encoded.
4350 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4353 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4354 functions: silc_[encode/decode]_pem. Also added function
4355 silc_encode_pem_file to PEM encode with newlines ('\n') for
4358 * SILC public keys are now encoded either PEM or binary. Same
4359 option is for private keys as well. By default private keys
4360 are binary encoded and public keys PEM encoded. Silly HEX
4361 encoding were removed.
4363 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4364 function to create fingerprints.
4366 * Fixed a bug in SHA1; does not change the original data anymore.
4368 * Partly implemented INFO command on client and server side.
4369 Fixed CLEAR command. Changes to SERVER command; show current
4370 server(s) when giving command without arguments. Added
4371 VERSION command to client.
4373 * Added check to server that unregistered connections cannot
4374 execute commands (unless it is specificly allowed).
4376 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Fixed screen refresh.
4380 * Fixed channel joining bug from client. On some circumstances
4381 client tried to join to a channel it had already joined.
4383 * Added public key verification process into client's protocol.c.
4384 The client now verifies the public key from user and saves
4385 it into ~./silc/serverkeys/ directory.
4387 Added into: clientutil.[ch]: silc_client_verify_server_key.
4389 * Changed SKE protocol's silc_ske_initiator_finish function
4390 to accept callback function that verifies the received public
4391 key. Removed old silc_ske_verify_public_key function.
4393 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4396 silc_pkcs_private_key[_data]_set.
4398 * Made the password and public authentication more cleaner in
4399 server's protocol.c.
4401 * Removed historic and obsolete protocol `channel_auth' from
4402 both client and server.
4404 * Removed wrong way of sending command status messages from
4405 server to client in server's command.c. The old way violated
4406 protocol specification.
4408 Changes to silccore/silccommand.[ch]: removed
4409 silc_command_encode_status_payload -> not needed anymore,
4410 changed silc_command_encode_payload_va to accept extra
4411 argument on variable argument list. The argument type must
4412 now be provided to the function. Also, added new function:
4413 silc_command_encode_reply_payload_va which is same as
4414 normal command_encode_payload_va except command status type
4415 is provided as extra argument.
4417 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Added ~./silc directory handling. The directory includes the
4420 public and private keys for the client.
4422 Added silc_client_check_silc_dir, silc_client_create_identifier
4423 and silc_client_load_keys.
4425 * Implemented SILC protocol compliant public key. Added public
4426 and private key saving to and loading from files.
4428 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4429 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4430 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4431 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4432 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4434 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4435 silc_pkcs_load_[public/private]_key.
4437 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Added silc_server_get_route (route.[ch]) to get connection
4440 data for the fastest route for given ID.
4442 * Implemented INVITE command on client and server. The command
4443 were re-defined in the SILC Protocol Specification and the
4444 implementation now complies with the specification.
4446 * Implemented PING command on client and server.
4448 * Implemented NAMES command on client and server. The server side
4449 supports currently only normal server not router server yet.
4450 Some changes to NAMES definition in SILC protocol specification.
4452 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Implemented LEAVE command on client and server.
4456 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4457 again. This change was made to the protocol as well. Server
4458 should not violate the protocol specification anymore.
4460 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4463 was tested. SOCKS4 was not but should work anyway.
