3 * Check for NULL socket pointer in the function
4 silc_server_packet_send_to_channel_real. Affected file
7 * Fixed the BAN notify handling to correctly remove ban
8 list. Affected file silcd/packet_receive.c.
10 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
12 * Fixed some header addition to Toolkit distribution in
13 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
15 * Added lib/silcclient/client_ops_example.h as an template
16 file for application programmers to quickly start using
17 the SilcClientOperation functions in their application.
18 Updated the lib/silcclient/README as well to tell about this
19 nice file made available.
21 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
23 * Call silc_server_remove_from_channels when removing client
24 entry when NO_SUCH_CLIENT_ID was received. Affected file
25 is silcd/command_reply.c.
27 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
29 * Added server & router operator statistics updating. Affected
30 file silcd/packet_receive.c and silcd/command.c.
32 * Fixed the SERVER_SIGNOFF notify handling on normal server
33 not to save the history information for clients. Same was
34 fixed earlier in remove_clients_by_server function, but not
35 here. Affected file silcd/packet_receive.c.
37 * Raised the default connection-retry count from 4 to 7 in
38 server. Affected file silcd/server.h.
40 * Cancel any possible reconnect timeouts when we start the
41 key exchange. Affected file silcd/server.c.
43 * Do not reconnect on connection failure when SCONNECT was
44 given. Affected files silcd/server.[ch].
46 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
48 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
50 * Fixed the NICK command to always give the unformatted
51 nickname to the one giving the NICK command. If unformatted
52 nickname is cached already it will be formatted and the
53 local entry will always get the unformatted nickname.
54 Affected file lib/silcclient/idlist.c.
56 * Fixed some double frees from client library commands.
57 Affected file is lib/silcclient/command.c.
59 * Fixed CUMODE command in server to assure that no one can
60 change founder's mode than the founder itself, there was a
61 little bug. Affected file silcd/command.c.
63 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
65 * Removed the SilcClientCommandDestructor from the client
66 libary, it is not needed anymore. Affected files are
67 lib/silcclient/silcapi.h, command[_reply].[ch],
68 client_notify, idlist.c.
70 * Fixed GETKEY command to first resolve client, and then
71 resolve the server only if the client was not found, instead
72 of resolving both at the same time. Affected file is
73 lib/silcclient/command.c.
75 * Added silc_client_start_key_exchange_cb and lookup the
76 remote hostname and IP address before starting the key
77 exchange with server. The affected file is
78 lib/silcclient/client.c.
80 * The server's public key is now saved using the IP address
81 of the server and not the servername for the filename.
82 The hostname public key filename is checked as an fall back
83 method if the IP address based filename is not found.
85 Fixed the GETKEY command to save the fetched server key
88 Print the remote server's hostname now when new key is
89 received during connection process. Affected file is
90 irssi/src/silc/core/client_ops.c.
92 * Return always our own public key to the client if it asks
93 for it with GETKEY command. Affected file silcd/command.c.
95 * Removed the use_auto_addr variable from default config
96 file since it was in wrong section. Affected file is
99 * Fixed TOPIC_CHANGE notification to not route it when it
100 was sent using silc_server_send_notify_to_channel function.
101 Affected file silcd/command.c.
103 * Fixed silc_server_send_notify_kicked to send the kicker's
104 Client ID also, it was missing. Affected files are
105 silcd/command.c, silcd/packet_send.[ch].
107 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
109 * Do not save client history information in SERVER_SIGNOFF.
110 Fixes the bug in normal server that it does not detect
111 the client becoming valid after the server becomes back
112 online. Affected file silcd/server_util.c.
114 * Added `sock_error' field into the SilcSocketConnection
115 context. When error occurs during socket operation (read
116 or write) the error is saved. Added also new function
117 silc_socket_get_error to return human readable socket error
118 message. Affected files are lib/silcutil/silcsockconn.[ch],
119 lib/silcutil/unix/silcunixsockconn.c, and
120 lib/silcutil/win32/silcwin32sockconn.c.
122 * The server now prints the socket error message in the
123 signoff for client. Affected file silcd/server.c.
125 * Fixed the `created' channel information sending from router
126 to server in JOIN command. Checks now whether the channel
127 really was created or not and set it according that.
129 Fixed the JOIN command to use the client entry's current
130 ID during the joining procedure instead of the one it sent
131 in the command (it is checked though), since it can change
132 between the packet processing and command processing, and
133 would just case unnecessary pain in the client end. Affected
134 file silcd/command.c.
136 * Fixed a channel key payload sending to use correct channel
137 ID when the server was forced to change the channel's ID by
138 router. Router sent the key payload with the old Channel ID.
139 Affected file silcd/packet_receive.c.
141 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
143 * Call silc_server_save_channel_key only if the key payload
144 was provided in the JOIN command's command reply. Affected
145 file silcd/command_reply.c.
147 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
149 * Fixed silc_mp_sizeinbase to return the value correctly with
150 MPI. Affected file lib/silcmath/mp_mpi.c.
152 * Fixed the stop_server signal to correctly stop the scheduler
153 and gracefully stop the server when SIGTERM or SIGINT signals
154 are received. Affected file silcd/silcd.c.
156 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
158 * Simple handling of TERM and HUP signals. Also added some log
159 flushing call around. Affected file is
162 * Fixed small bugs in silclog.c. Now buffering output will take
163 effect after 10 seconds since startup: This will ensure that
164 no important startup messages are lost. Also output redirection
165 will preserve original format ([Date] [Type] message).
166 Affected file is lib/silcutil/silclog.c.
168 * Added two options to the config file, in the logging section:
169 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
170 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
172 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
174 * Do not print the warning about log files not being initialized
175 more than once to avoid excess logging. Affected file is
176 lib/silcutil/silclog.c.
178 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
179 the SIM copying in make install in Makefile.am.pre.
181 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
183 * Rewritten silclog APIs. Globally interesting changes follows:
184 silc_log_set_files() changed to silc_log_set_file().
185 silc_log_set_callbacks() changed to silc_log_set_callback().
186 ROBOdoc documented silclog header file.
187 SilcLogCb now returns bool to wether inihibit the default
188 handler or not (to keep the old behaviour return always TRUE).
189 The new APIs should also fix the problem of the
190 silcd_error.log file that was written in the current directory.
193 Log files streams will remain opened after silc_log_set_file()
194 call, means less CPU usage notably on high traffic servers.
195 File streams are now full buffered, and flushed to the disk
196 every 5 minutes, lesses HD activity and CPU usage.
197 Messages can be redirected, allowing admins to configure
198 one single logfile for all server messages.
199 the silc_log_quick global variable to activate fast-logging.
200 Affected files lib/silcutil/silclog.[ch]
202 * Changed some code to conform new silclog APIs. Affected
203 files are doc/example_silcd.conf.in, silcd/server.c
204 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
207 * Fixed a memory leak that could occur in some situations.
208 Affected file silcd/serverconfig.c.
210 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
212 * Added the silc_client_del_client to remove the client from
213 all channels as well. Affected file lib/silcclient/idlist.c.
215 * Fixed the client library to correctly remove the client
216 from all channels when the client entry is being destroyed.
217 Affected file lib/silcclient/client_notify.c, command.c.
219 * Added auto-nicking support to the client library. If the
220 applicatio now sets client->nickname it will be sent to the
221 server after connecting by the library. This way for example
222 SILCNICK (or IRCNICK) environment variables will have effect
223 and always change the nickname automatically to whatever
224 it is wanted. Affected file lib/silcclient/client.[ch].
226 * Renamed silc_server_command_bad_chars to the
227 silc_server_name_bad_chars and moved it to the
228 silcd/server_util.[ch]. Added also new function
229 silc_server_name_modify_bad to return nickname that
230 includes bad characters as new nickname without those
231 bad characters. This check and modify is now used in
232 silc_server_new_client when the username is initially set
233 as nickname, so it must be checked to be valid nickname.
234 Affected file silcd/packet_receive.c.
236 * The nickname length is now taken from the packet for real
237 and not trusted to strlen() since it clearly can return
238 wrong length for nickname including bad characters. This
239 also applies to channel names. Affected file silcd/command.c.
241 * Removed the lib/silcsilm/modules directory. Modules are now
242 compiled into the lib/silcsim. Fixed the copying of the
243 modules to follow symbolic links in Makefile.am.pre.
245 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
247 * Fixed silc_string_regexify list creation. Fixes bugs with
248 BAN and INVITE commands in server. The affected file is
249 lib/silcutil/unix/silcunixutil.c.
251 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
253 * Removed the command destructor entirely from the server's
254 command and command reply routines. It is not needed, and
255 its usage was buggy and caused crashes. Affected files are
256 silcd/command[_reply].[ch].
258 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
260 * Cancel protocol and NULL sock->protocol if timeout
261 occurred during protocol. Affected file silcd/server.c.
263 * Cancel protocol timeouts always before calling the final
264 callback, to assure that after final callback is called
265 no other state will be called for the protocol anymore.
266 Affected file silcd/protocol.c.
268 * Print error log if incoming connection configuration could
269 not be found. Affected file silcd/server.c.
271 * Fixed JOIN command to correctly save the founder mode
272 to the client on normal SILC server, when the channel
273 was created by the router. Affected file silcd/command.c.
275 * Fixed LIST command (hopefully) to send correct reply
276 packets. Affected file silcd/command.c.
278 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
280 * The silc_packet_receive_process now returns FALSE if the
281 read data was invalid packet, and TRUE if it was ok.
283 The server now checks that if unauthenticated connection
284 sends data and its processing fails the server will close
285 the connection since it could be a malicious flooder.
287 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
289 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
291 * Make sure the warning about error opening a log file is
292 printed only once and not everytime it fails (produces
293 too much useless log). Affected file lib/silcutil/silclog.c.
295 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
297 * Made the silc_server_daemonise() function more readable.
298 Affected file silcd/server.c.
300 * Pid file is now optional, the user may comment it out from
301 the config file. Removed define SILC_SERVER_PID_FILE, we
302 don't need a default any longer. Affected file
303 configure.in.pre, lib/Makefile.am.pre.
305 * Make some use of the pid file. The server now dies at startup
306 if it detects a valid pid file on his path. The server would
307 die anyway in this circumstance, because of the bind() failure.
308 Affected file silcd/silcd.c.
310 * No longer compiling lib/dotconf.
312 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
314 * Fixed JOIN command parsing not to crash. Affected file
315 lib/silcclient/command.c.
317 * Fied the NICK_CHANGE notify to add the new client entry
318 even it is resolved. This removes an <[unknown]> nick
319 thingy bug in the client. Affected file is
320 lib/silcclient/client_notify.c.
322 * Do not try to allocate 0 bytes (efence does not like it)
323 in lib/silccore/silccomand.c when encoding payload.
325 * Do not take IRCNICK as nickname in Irssi SILC client since
326 it is not possible to set nickname before hand connecting
327 the server (TODO has an entry about adding auto-nicking
330 * Changed the silc_server_command_pending to check whether
331 there already exists an pending entry with the specified
332 command, command identifier and pending callback. This is
333 to fix IDENTIFY and WHOIS related crashes that may register
334 multiple pending commands with same identifier. Affected
335 file silcd/command.c.
337 * Fixed the server to reconnect to the router even if it
338 was already reconnecting and EOF was received. This to
339 fix a possibility that the server wouldn't ever try to
340 auto-reconnect to the router. Affected file silcd/server.c.
342 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
344 * Fixed the server's password authentication to use the
345 length of the locally saved password, and not the one
346 sent in the packet. Affected file silcd/protocol.c.
348 * Fixed same password authentication problem in the
349 Authentication Payload handling routines in
350 lib/silccore/silcauth.c.
352 * Yet another password authentication problem fixed with
353 channel password handling in silcd/command.c.
355 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
357 * If first character of string in silc_parse_userfqdn is '@'
358 then do not parse it. Affected file is
359 lib/silcutil/silcutil.c.
361 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
363 * Fixed minor bug in IDENTIFY command reply sending, which
364 caused various weird problems during JOIN when it was
365 resolving names for users. Affected file silcd/command.c.
367 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
369 * Fixed the IDENTIFY command reply sending to chech better valid
370 clients. It was possible to send incomplete list of replies.
371 Affected file silcd/command.c.
373 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
375 * Added silc_client_command[s]_[un]register functions now to
376 dynamically register the commands in client library. Removed
377 the static table of commands. This allows the client library
378 to call commands without causing the application to know about
379 what commands library has called.
381 Removed the INFO command reply kludge to detect when the command
382 was called by library. Now library use its own command reply
383 function for INFO command.
385 Added function silc_client_command_call to call a command.
386 Application can use it to call command, not access the structure
389 Now all commands that are sent by the client library (not
390 explicitly sent by application) use own command reply functions.
392 Affected files around lib/silcclient/ and in
393 irssi/src/silc/core/.
395 * Fixed the WHOIS command reply sending to chech better valid
396 clients. It was possible to send incomplete list of replies.
398 Fixed the WHOIS and IDENTIFY to send the request to router
399 if normal server did not do it and did not find any results.
401 Affected file silcd/command.c.
403 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
405 * Moved the internal data from SilcClient context into its
406 own file, not accesible to application. Affected files
407 lib/silcclient/client.h and lib/silcclient/client_internal.h,
408 and other files in client library.
410 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
412 * Added doc/examples installation target in Makefile.am.pre.
415 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
417 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
418 commands the found client entry will be removed from the
419 cache, after notifying application about the error. Affected
420 file lib/silcclient/command_reply.c.
422 * Changed the /MSG to check for exact nickname user gave, and
423 not let `nick' match `nick@host' if it is only one found. Now,
424 user must type the exact nickname (like nick@host2) even if
425 there are no more than one same nicks found. This is to avoid
426 a possibility of sending nickname to wrong nickname since
427 `nick' could match `nick@host'. Affected file is
428 irssi/src/core/silc-servers.c.
430 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
432 * Do not print "you are now server operator" or similar when
433 giving /away command. Affected files are
434 irssi/src/silc/core/client_ops.c, silc-servers.h.
436 * Made the silc_server_command_pending_error_check to send
437 the same command reply payload it received back to the
438 original sender of the command. This way all arguments
439 that was received by the server will be received by the
440 client too. Affected file silcd/command.c.
442 * Added the silc_idcache_add to return the created cache entry
443 to a pointer. Affected file lib/silccore/silcidcache.[ch].
445 * Add global clients to expire if they are not on any channel.
446 This is because normal server will never know if they signoff
447 if they are not on any channel. The cache expiry will take
448 case of these entries. This is done by normal servers only.
449 The affected files are silcd/command_reply.c,
450 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
452 * If server receives invalid ID notification for WHOIS or
453 IDENTIFY and the ID exists in the lists, it is removed.
454 Affected file silcd/command_reply.c.
456 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
457 in client then client entry that it matches is searched and
458 the nickname is printed on the screen for user. Affected
459 file irssi/src/silc/core/client_ops.c.
461 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
463 * Use cache entry expire time in the LIST command reply to
464 purge old entries from the cache after the LIST command
465 reply has been received. This way we don't have non-existent
466 entries in the cache for too long. Affected file is
467 silcd/command_reply.c.
469 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
471 * If we are normal server, and we've not resolved client info
472 in WHOIS or IDENTIFY from router, and it is global client,
473 we'll check whether it is on some channel. If it is not
474 then we cannot be sure about its validity and will resolve it
475 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
476 file silcd/command.c.
478 * Search channel by name (if possible) rather than by ID
479 in IDENTIFY command's command reply. Affected file is
480 silcd/command_reply.c.
482 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
484 * Distribute to the channel passphrase in CMODE_CHANGE notify.
485 Updated specs and implemented it. Affected file silcd/command.c,
486 silcd/packet_send.c and silcd/packet_receive.c.
488 * Implemented the <founder auth> payload handling in the JOIN
489 command. If provided all conditions for channel joining
490 except requirement to provide correct passphrase can be
491 overrided by the channel founder. Updated the protocol specs.
492 Affected file silcd/command.c.
494 Added support for founder auth in JOIN command in client
495 library. Fixed the parsing of the JOIN command now to support
496 all options as they should be. The affected file is
497 lib/silcclient/command.c.
499 * Optimized the WHOIS and IDENTIFY commands to send the request
500 to router only if it includes nicknames or other names. If
501 they include only IDs then check the local cache first before
502 routing. Affected file is silcd/command.c.
504 * Added channels topic announcements. Affected file is
505 silcd/packet_receive.c and silcd/server.c.
507 * Fixed the silc_server_send_notify_topic_set to really destine
508 the packet to channel. Affected file silcd/packet_send.c.
510 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
511 library. Affected file lib/silcclient/client_notify.c.
513 * Added UMODE announcements. Affected file silcd/server.c.
515 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
517 * Memory leak fixes in:
519 lib/silcutil/silcsockconn.c
520 lib/silcske/silcske.c
523 lib/silccrypt/silcpkcs.c
524 lib/silccore/silccommand.c
525 lib/silccore/silcidcache.c
530 * ROBOdoc documented the lib/silcske/groups.h file and a
531 bit changed the interface for better.
533 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
535 * Update the client entry context in the ID cache after
536 nick change. Affected file lib/silcclient/command.c.
537 Fixes the CUMODE command when regaining founder privileges,
538 and a little WHOIS problem.
540 * Fixed silc_net_gethostbyname to correctly call the
541 inet_ntop. Affected file lib/silcutil/silcnet.c.
543 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
545 * Added IPv6 support checking to the configure.in.pre, added
546 also --enable-ipv6 option to override the check. Affected
547 file configure.in.pre.
549 * The silc_thread_create now calls the start function
550 directly if threads support is not compiled in. Removes
551 ugly #ifdef's from generic code. Affected files are
552 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
554 * Added silc_net_gethostby[name/addr]_async to asynchronously
555 resolve. Affected files are lib/silcutil/silcnet.[ch].
557 * Added support for rendering IPv6 based server, client and
558 channel IDs. Affected file lib/silcutil/silcutil.c.
560 * Added support for creating IPv6 based server IDs. Affected
561 file is silcd/serverid.c.
563 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
565 * Added silc_net_gethostby[addr/name] into the
566 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
567 routines. Added silc_net_is_ip[4/6]. Affected file is
568 lib/silcutil/unix/silcunixnet.c. All routines that take
569 address as argument now supports both IPv4 and IPv6 addresses.
571 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
573 * Fixed LIST command reply sending in server. Affected file
576 * Server now sends the kicker's client ID in the KICK notify
577 to the kicked client. Affected file silcd/command.c.
579 * The client library now parses the kickers client ID and
580 UI displays it. Affected files lib/silcclient/client_notify.c
581 and irssi/src/silc/core/silc-channels.c, module-formats.c.
583 * Made all payload parsing function prototypes consistent.
584 They all take now const unsigned char * and uint32 pair as
585 the payload data instead of SilcBuffer. Changes all around
586 the source tree. Other unsigned char* -> const unsigned char*
587 changes around the tree as well.
589 * Optimized SFTP client and server packet sending not to
590 allocate new buffer for each packet but to recycle the
591 first allocated buffer. Affected files are
592 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
594 * Optimized the SFTP client to use SilcList instead of
595 SilcDList for requests, because it is faster. Affected file
596 is lib/silcsftp/sftp_client.c.
598 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
599 into lib/silccore/silcid.[ch].
601 Renamed silcpayload.[ch] into silcargument.[ch].
603 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
605 * If client entry is deleted with active key agreement
606 session, abort the session.
608 The silc_client_abort_key_agreement now calls the completion
609 callback with new SILC_KEY_AGREEMENT_ABORTED status.
611 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
614 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
616 * Don't use __restrict in older GCC's. Affected file is
617 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
619 * silc_net_localhost now attempts to reverse lookup the
620 IP/hostname. Affected file lib/silcutil/silcnet.c.
622 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
623 command. It can be used to gain founder privileges at
624 the same time when joining the channel.
626 Defined that the SILC_NOTIFY_TYPE_KICKED send the
627 kicker's client ID as well. Updated protocol specs.
629 Defined that the server must send SILC_COMMAND_IDENTIFY
630 command reply with error status to client who sent
631 private message with invalid client ID.
633 Updated the protocol specification.
635 * Added silc_server_send_command_reply to send any
636 command reply. Affected file silcd/packet_send.[ch].
638 * Added silc_id_payload_encode_data to encode ID payload
639 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
641 * The server now send IDENTIFY command reply with error
642 status if client ID in private message is invalid. Affected
643 file silcd/packet_receive.c.
645 * Save the server key file with server's IP address in
646 the filename instead of hostname. The affected file is
647 irssi/src/silc/core/client_ops.c.
649 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
651 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
654 * Added libtool support for compiling shared objects in
655 lib/silcsim. Affected file configure.in.pre and
656 lib/silcsim/Makefile.am. Original patch by cras.
658 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
660 * Pid file configuration, and server's config file fixes
661 patch by toma. Updated CREDITS file.
663 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
665 * Fixed silc_client_channel_message to not try to decrypt
666 the message twice if it resolved the destination client
667 information. This could cause of dropping one channel
668 message. Affected file lib/silcclient/client_channel.c.
670 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
672 * Added silc_client_run_one into lib/silcclient/silcapi.h and
673 lib/silcclient/client.c. This function is used when the SILC
674 Client is run under some other scheduler, or event loop or
675 main loop. On GUI applications, for example this may be
676 desired to used to run the client under the GUI application's
677 main loop. Typically the GUI application would register an
678 idle task that calls this function multiple times in a second
679 to quickly process the SILC specific data.
681 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
683 * Fixed silc_server_drop() for dropping the supplementary
684 groups as well, this could cause a security hole on some
687 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
689 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

693 to run server on foreground. A patch by debolaz.
694 Affected files silcd/server.c, silcd/silcd.c.
696 * Fixed MOTD to return the MOTD file server name. Affected
697 file silcd/command.c.
699 * Added INFO command reply handling to the Irssi SILC Client.
700 Affected file irssi/src/silc/core/client_ops.c.
702 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Fixed the silc_idcache_list_* routines to really support
705 the dynamic list. Fixes a crash. Affected file is
706 lib/silccore/silcidcache.c.
708 * Fixed the LIST command reply to really call LIST command's
709 pending callbacks. Affected file silcd/command_reply.c.
711 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
713 * Update conn->local_entry->nickname after giving NICK
714 command. Affected file lib/silcclient/command.c.
716 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
718 * Added the [pid] option to the silcd configuration file
720 Affected files: serverconfig.[ch] and silcd.c
722 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
724 * Save fingerprint in WHOIS command reply in server.
725 Affected file silcd/command_reply.c.
727 * Fixed NICK commands pending callback registration.
728 Affected file lib/silcclient/command.c.
730 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
732 * Use ++server->cmd_ident when sending commands in server,
733 instead of random number. Affected file silcd/command.c.
735 * Fixed GETKEY command reply to call actually GETKEY pending
736 command callbacks. Affected file silcd/command_reply.c.
738 * A bit stricter check for nicknames. Check for same nickname
739 in NICK command also. Affected file silcd/command.c.
741 * Do not call INFO command everytime client ID changes, only
742 during first connecting. Affected file lib/silcclient/client.c.
744 * Set the new nickname only after successful command reply for
745 NICK command is returned by server. Affected file
746 lib/silcclient/command.c.
748 * Remove nicknames from nicklist during server_signoff notify.
749 Should fix /NAMES bit more. The affected file is
750 irssi/src/silc/core/silc-channels.c.
752 * Added `fingerprint' field to the SilcIDListData in the
753 silcd/idlist.h to hold the fingerprint of the client's
756 Send the fingerprint of the client's public key in WHOIS
759 Affected files silcd/command.c, and silcd/idlist.[ch].
761 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
762 create fingerprint from given data.
764 * Show the fingerprint of the client's public key in WHOIS.
765 Affected files irssi/src/module-formats.[ch] and
766 irssi/src/silc/core/client_ops.c.
768 * Format the multiple same nicknames also during JOIN and
769 NICK_CHANGE notifys. Affected file is
770 lib/silcclient/client_notify.c.
772 * Do not print error on screen for invalid private message
773 payload since it can come if someone is sending private
774 messages with wrong key. Affected file
775 lib/silccore/silcprivate.c.
777 * Fixed multiple concurrent /PING crash. Affected file
778 lib/silcclient/command.c.
780 * Changed the wrong ID encoding. All IP addresses must be
781 in MSB first order in encoded format. They were encoded
782 wrong and was in LSB format. Affected files are
783 silcd/serverid.c, lib/silcutil/silcutil.c.
785 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
787 * Call the `connect' client operation through the scheduler
788 in case of error. Affected file lib/silcclient/client.c.
790 * Call the `failure' client operation even if the error
791 occurred locally during a protocol. Affected file is
792 lib/silcclient/protocol.c.
794 * Added support of sending LIST command to router from normal
795 server. This way normal server can get list of all channels
796 in the network too. Fixed the channel list sending in the
797 server too. Affected files are silcd/command.c, and
798 silcd/command_reply.[ch].
800 * Added silc_server_update_channels_by_server and
801 silc_server_remove_channels_by_server. They are used during
802 disconnection of primary router and in backup router protocol.
803 Affected file silcd/server_util.[ch], silcd/server.c and
804 silcd/server_backup.c.
806 * Fixed channel adding to global list in IDENTIFY command
807 reply in server. Affected file silcd/command_reply.c.
809 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
811 * If the incoming packet type is REKEY or REKEY_DONE process
812 that packet always synchronously. Fixes yet another MAC
813 failed error on slow (dialup) connections. Affected file
814 lib/silcclient/client.c and silcd/server.c.
816 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
818 * Call check_version SKE callback for initiator too. Affected
819 file lib/silcske/silcske.c.
821 * Implemented fix for security hole found in the SKE that was
822 fixed in the specification few days back; the initiator's
823 public key is now added to the HASH value computation.
824 Added backwards support for the old way of doing it too, for
825 old clients and old servers. Affected file is
826 lib/silcske/silcske.c.
828 * Enabled mutual authentication by default in SKE. If initiator
829 is not providing mutual authentication the responder will
830 force it. This will provide the proof of posession of the
831 private key for responder. The affected files are
832 lib/silcclient/protocol.c and silcd/protocol.c.
834 * Do not cache anymore the server's public key during SKE.
835 We do mutual authentication so the proof of posession of
836 private key is done, and if the server is authenticated in
837 conn auth protocol with public key we must have the public
838 key already. Affected file silcd/protocol.c.
840 * Added new global debug variable: silc_debug_hexdump. If
841 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
842 file lib/silcutil/silclog.[ch].
844 * Fixed compilation warning due to char * -> const char *.
845 Affected files lib/silcutil/silcnet.h, and
846 lib/silccore/silcauth.[ch].
848 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
850 * Fixed CMODE command when new channel key was created. If
851 the creation failed the old key was removed. Next time giving
852 same command would crash the server since the old key was
853 freed already. Affected file silcd/command.c.
855 * Fixed the silc_server_announce_get_channels to not crash
856 on reconnect. Affected file silcd/server.c.
858 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
860 * Added silc_log_set_debug_string function to set a regex
861 string to match for debug output. Only the function names,
862 or filenames matching the given debug string is actually
863 printed. This way it is possible to filter out those debug
864 strings that user is not interested in.
866 Fixed a bug in silc_string_regexify.
868 Affected files lib/silcutil/silclog.[ch], and
869 lib/silcutil/unix/silcunixutil.c.
871 * Changed the -d options in both server and Irssi SILC client
872 to take the debug string as argument. Affected files
873 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
875 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
877 * Added silc_hash_babbleprint to create a Bubble Babble
878 Encoded fingerprint. The encoding is developed by Antti
879 Huima (draft-huima-babble-01.txt), and it creates human
880 readable strings out of binary data. Affected file
881 lib/silccrypt/silchash.[ch].
883 * Print the babble print now in addition of fingerprint as well
884 in Irssi SILC client. Affected files are
885 irssi/src/fe-common/silc/module-formats.[ch],
886 irssi/src/fe-common/silc/core/client_ops.c.
888 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
890 * Fixed a security problem found in SKE. The initiator's
891 public key too is now added to the HASH hash value creation
892 which is signed by the responder to create the SIGN value.
893 This will prevent anyone in the middle to lie to the responder
894 about the initiator's public key. If this is done now, the
895 man in the middle will get caught. Updated the protocol
898 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
900 * Better installation directory handling. Configure module
901 paths and other paths automatically to example_silc* files
902 in doc/. A patch by toma.
904 * Fixed compiler warning from MPI library, and from SILC RNG.
907 * Added SILC_SERVER_PID_FILE to define the pid file for server.
908 It can be configured with ./configure. A patch by toma.
910 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
912 * Find correct make to use in prepare-clean. A patch by
913 toma. Affected file prepare-clean.
915 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
917 * Added irssi variables use_auto_addr, auto_bind_ip,
918 auto_bind_port and auto_public_ip.
920 * Changed the interface for silc_client_send_key_agreement
921 in lib/silcclient/silcapi.h
925 irssi/src/silc/core/silc-core.c
927 lib/silcclient/silcapi.h
928 irssi/src/silc/core/silc-channels.c
929 lib/silcclient/client_keyagr.c
932 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
934 * Added silc_pkcs_public_key_compare to compare two
935 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
937 * Check that the client who set the founder mode on the
938 channel is the same client that is giving the founder
939 mode to itself. It is done by comparing the saved public
940 key (it is saved even in the authentication is passphrase).
941 Affected file silcd/command.c.
943 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
945 * Do not process packet for disconnected socket connection.
946 Affected file lib/silccore/silcpacket.c.
948 * Process the DISCONNECT packet through scheduler in the
949 client library. Affected file lib/silcclient/client.c.
951 * Fixed the silc_client_packet_parse to not to increase
952 the packet sequence number if the conn->sock and the
953 current socket connection is not same. This can happen
954 for example during key agreement when the conn includes
955 multiple socket connections (listeners). Affected file
956 lib/silcclient/client.c.
958 * The sender of the file transfer request now provides also
959 the pointer (listener) for the key exchange protocol. If
960 the listener cannot be created then it sends empty key
961 agreement and lets the receiver provide the listener.
963 Added `local_ip' and `local_port' arguments to the
964 silc_client_file_send. If they are provided they are used,
965 if not then it will attempt to find local IP address, if
966 not found or bind fails then the remote client will provide
969 Affected files are lib/silcclient/client_ftp.c and
970 lib/silcclient/silcapi.h.
972 * Extended the FILE SEND command to support defining the
973 local IP and port for key exchange listener. They are
974 optional. Affected file irssi/src/silc/core/silc-servers.c.
976 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
978 * Defined to WHOIS command reply the sending of fingerprint
979 of the client's public key (if the proof of posession of the
980 corresponding private key is verified by the server).
981 Updated to the protocol specification.
983 * Added support of receiving the client's public key's
984 fingerprint in command reply in client library. Affected
985 file is lib/silcclient/command_reply.c, and
986 lib/silcclient/idlist.[ch].
988 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
990 * Do not send over 128 chars long nickname to the server
991 in NICK command. Affected file lib/silcclient/command.c.
993 * Do not send over 256 chars long channel names to the server
994 in JOIN command. Affected file lib/silcclient/command.c.
996 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
998 * Assure that silc_server_close_connection cannot be called
999 twice for same socket context. Affected file is
1002 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1004 * Send error message to application if opening file for
1005 writing during file transfer fails. Affected file is
1006 lib/silcclient/client_ftp.c.
1008 Remove all file transfer sessions for a client that we're
1009 removing from ID cache.
1011 Affected file is lib/silcclient/client_ftp.c.
1013 * Fixed silc_net_addr2bin to return correct address. Affected
1014 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1016 * Fixed file transfer session removing on signoff notify.
1017 Affected file irssi/src/silc/core/silc-servers.c.
1019 * Added the SilcClientFileError to be returned in the monitor
1020 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1021 Affected file lib/silcclient/silcapi.h.
1023 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1025 * Fixed a crash in silc_client_ftp_free_sessions and
1026 silc_client_ftp_session_free_client. Affected file
1027 lib/silcclient/client_ftp.c.
1029 * Added `disabled' field in the SilcChannelEntry in the server
1030 to indicate if the server entry is disabled. Affected file
1031 silcd/idlist.h, silcd/command[_reply].c.
1033 * SILC server adds now /var/run/silcd.pid everytime it is
1034 started. Affected file silcd/silcd.c.
1036 * Added silc_server_packet_send_clients to send a packet to
1037 the provided table of client entries. Affected file
1038 silcd/packet_send.[ch].
1040 * Fixed a crash in client resolving in client_prvmsg.c in
1041 client library. Affected file lib/silcclient/client_prvmsg.c.
1043 * Do not actually remove the client directly from ID cache
1044 during SERVER_SIGNOFF, but invalidate it. This way we
1045 preserve the WHOWAS info for the client. Affected file
1046 silcd/server_util.c.
1048 * Fixed SERVER_SIGNOFF notify handling in the server. The
1049 server is now able to process incoming SERVER_SIGNOFF notify
1050 for a server that it doesn't even know about. It will remove
1051 the clients provided in the notify. Affected file
1052 silcd/packet_receive.c.
1054 * Check for partial packet in data queue after every packet that
1055 was found from the queue. Return and wait for more data if
1056 there is partial data in queue. Affected file is
1057 lib/silccore/silcpacket.c.
1059 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1061 * Added SilcClietFileError enum to indicate error in
1062 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1063 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1064 Affected files lib/silcclient/silcapi.h and
1065 lib/silcclient/client_ftp.c.
1067 * Check that newsize in silc_buffer_realloc is larger than
1068 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1070 * Added better monitor of file transfers. It now monitors
1071 key agreement protocol during the file transfer too. Added
1072 error reporting too. Affected files
1073 irssi/src/silc/core/silc-servers.c,
1074 irssi/src/fe-common/silc/module-formats.[ch].
1076 * Wrote a help file for FILE command.
1078 * Added silc_rng_global_get_byte_fast to get not-so-secure
1079 random data as fast as possible. Random data is read from
1080 /dev/urandom if available and from the SILC RNG if not
1081 available. It is used in padding generation. Affected file
1082 lib/silccrypt/silcrng.[ch].
1084 * All packets in client library are now processed synchronously.
1085 Optimized packet processing a lot. Affected file
1086 lib/silcclient/client.c.
1088 * All server connection packets are processing synchronously
1089 now in server, to optimize packet processing. Affected file
1092 * Include files are installed now only in Toolkit distribution
1093 if make install is given. Affected files: all Makefile.am's.
1095 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1097 * Assure that silc_client_notify_by_server_resolve does not
1098 resolve the client information multiple times. If it cannot
1099 be found by the first it cannot be found at all. Affected
1100 file lib/silcclient/client_notify.c.
1102 * Fixed WHOWAS command reply calling. Affected file
1103 lib/silcclient/command_reply.c.
1105 * Removed all references to silc_idlist_get_client from the
1106 Irssi SILC client since that call is internal call used by
1107 the library. The Irssi SILC client will use now client
1108 retrieval functions found in silcapi.h.
1110 * Fixed a bug in resolving nickname info before sending
1111 private message. It used freed memory. Affected file
1112 irssi/src/silc/core/silc-servers.c.
1114 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1116 * Assure my_channels statistics cannot go negative in server.
1117 Affected files silcd/server.c, silcd/server_util.c.

1133 * Added silc_net_localip to return local host's IP address.
1134 Affected file lib/silcutil/silcnet.[ch].
1136 * If key exchange or rekey protocol is active for a connection
1137 parse all packets syncronously since there might be packets
1138 in packet queue that we are not able to process without first
1139 processing packets before them. Affected file silcd/server,
1140 lib/silcclient/client.c.
1142 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1143 whether library should continue processing the packet.
1144 Affected file lib/silccore/silcpacket.h.
1146 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1190 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1191 is incomplete and is being resolved, it won't be resolved
1194 Make sure also that USERS command reply does not resolve
1195 twice information. Affected file is
1196 lib/silcclient/command_reply.c.
1198 Make sure that silc_client_get_clients_by_list does not
1199 resolve twice same information.
1201 * Check for valid client->id in the silc_server_free_client_data.
1202 Affected file silcd/server.c.
1204 * Fixed /GETKEY nick@server not to crash if the server entry
1205 is not found. Affected file lib/silcclient/command.c.
1207 * Fixed the silc_server_check_cmode_rights to check the
1208 requested modes correctly. Affected file silcd/command.c.

1212 * Better checks for non-printable chars in nick added.
1213 Affected file silcd/command.c.
1215 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Call the silc_server_udpate_servers_by_server in the
1218 primary router that comes back online in the backup resuming
1219 protocol. Otherwise it routes packets wrong. Affected file
1220 silcd/server_util.[ch], silcd/server_backup.c.
1222 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1224 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1225 lib/silcutil/silcbuffmt.[ch].
1227 * Redefined the SILC packet header to include the padding
1228 length. Affected file lib/silccore/silcpacket.[ch].
1230 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1231 length for maximum padding up to 128 bytes). Affected
1232 file lib/silccore/silcpacket.h.
1234 * Removed all backwards support for old 0.5.x MAC thingies.
1235 The SILC packet header change makes it impossible to be
1236 backwards compatible.
1238 * Send the ENDING packet with timeout in the backup resuming
1239 protocol. This is to assure that all routers has connected
1240 to the primary router. Affected file silcd/server_backup.c.
1242 * Changed the RNG to take the first IV from random data. It
1243 used to take it from zero actually. Changed the RNG also
1244 to use /dev/urandom during session. /dev/random is used
1245 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1247 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1249 * Changed the SILC packet header to have the first two bytes
1250 (the packet length) encrypted. Affected files aroung the
1251 code tree, lib/silccore/silcpacket.[ch]. Removed the
1252 SilcPacketCheckDecrypt callback. It is not needed anymore
1253 since the silc_packet_receive_process will determine now
1254 whether the packet is normal or special.
1256 * Implemented the unidirectional MAC keys. Affected files
1257 lib/silcske/silcske.c, silcd/protocol.c and
1258 lib/silcclient/protocol.c.
1260 * Implemented the packet sequence number to the MAC computation.
1261 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1262 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1263 lib/silcclient/protocol.c.
1265 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1267 * Allow backup router to announce servers. All servers
1268 announced by backup router are added to the global list
1269 automatically. Update hte server's socket to our primary
1270 router also when backup router announces a server.
1271 Affected file silcd/packet_receive.c.
1273 * Do not update the client->router in the function
1274 silc_server_udpate_clients_by_server if the client is on
1275 global list. We might fail to find any specific server
1276 for locally connected clients and local cell clients. They
1277 should still use the `from' and not `to' as client->router.
1278 This fixes backup router resuming protocol. Affected file
1279 silcd/server_util.c.
1281 * Decrease channel statistics count only if the channel
1282 deletion worked. Affected files are silcd/server.c and
1283 silcd/server_util.c.
1285 * Added silc_server_update_servers_by_server to update origin
1286 of all server entries. Used during backup router protocol.
1287 Affected files silcd/server_util.[ch], silcd/server.c. and
1288 silcd/backup_router.c.
1290 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1291 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1292 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1293 lib/silccrypt/silchmac.c.
1295 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1297 * Assure that router cannot reroute the same channel message
1298 to the sender. Affected file silcd/packet_receive.c.
1300 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1302 * Made better checks that the channel message is not sent
1303 to the router it came from. Affected file is
1304 silcd/packet_send.c. Fixed memory leak too.
1306 * Announce informations for incoming router connection, but
1307 only after checking if it is replaced by backup router.
1308 Affected file silcd/packet_receive.c.
1310 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Fixed the backup resuming protocol to work in multiple
1313 router environment. Affected file silcd/server_backup.c.
1315 * Route packet only to one router in the function
1316 silc_server_packet_send_to_channel. Affected file is
1317 silcd/packet_send.c.
1319 * Fixed silc_server_send_notify_dest to set the broadcast
1320 flag. Fixed the silc_server_send_notify_topic to actually
1321 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1322 Affected file silcd/packet_send.c.
1324 * Changed the SFTP Filesystem interface. Changed the
1325 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1326 the filesystem operation function. The SilcSFTPFilesystem
1327 is now a context that is allocated by all filesystem allocation
1328 functions and it already includes the operations structure
1329 and filesystem specific context. It is given as argument
1330 now to the silc_sftp_server_start. This made the interface
1331 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1332 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1334 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1336 * Changed the backup router adding and getting interfaces
1337 in the server. The router that will be replaced by the
1338 specified backup router is now sent as argument. Affected
1339 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1342 * Added silc_net_addr2bin_ne to return the binary form of
1343 the IP address in network byte order. Affected files
1344 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1346 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1348 * Check for existing server ID in silc_server_new_server
1349 and in silc_server_connect_to_router_final and remove the
1350 old entry if it exists. Affected file silcd/packet_receive.c,
1353 * Send the channel message always to only one router, either
1354 in upstream or downstream. Affected file is
1355 silcd/packet_send.c.
1357 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1359 * Wrote the definition of the backup resuming protocol to the
1360 protocol specification.
1362 * Removed one redundant channel key generation from normal
1363 server during joining procedure. Removed one redundant
1364 channel key sending from server to router during joining
1365 procedure. Affected file silcd/command.c.
1367 * Made minor bugfixes to the backup router resuming protocol.
1368 Affected file silcd/server_backup.c, server.c.
1370 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1372 * Added --disable-asm configuration option. Affected files
1373 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1376 * Implemented the backup resuming protocol that is used to
1377 resume the primary router position in the cell after the
1378 primary router comes back online. Affected files
1379 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1380 and silcd/server_util.[ch].
1382 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1384 * Sleep two (2) seconds after sending QUIT command to server.
1385 Affected file lib/silcclient/command.c.
1387 * Assure that if outgoing data buffer is pending do not force
1388 send any data. Affected file silcd/packet_send.c.
1390 * Assure that if outgoing data buffer is pending do not force
1391 send any data. Affected file lib/silcclient/client.c.
1393 * Implemented the backup router support when the primary router
1394 goes down. The servers and routers can now use the backup
1395 router as new primary router without loosing connectivity.
1397 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1400 in the server to indicate disabled entry. All data read
1401 from the connection will be ignored and no data is sent
1402 for entry that is disabled. Affected files are
1403 silcd/idlist.h, silcd/server.c.
1405 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1407 * Created SFTP client and server test programs in the
1408 lib/silcsftp/tests directory.
1410 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * Implemented memory filesystem (virtual filesystem) for
1413 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1416 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Implemented the SFTP (SSH File Transfer Protocol) to the
1419 lib/silcsftp. It includes SFTP client and SFTP server
1422 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1424 * Moved lib/silccore/silcprotocol.[ch] to the
1425 lib/silcutil library.
1427 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1428 take variable argument list pointer as argument. Affected
1429 file lib/silcutil/silcbuffmt.[ch].
1431 * Added silc_buffer_set function that is used to set data
1432 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1433 Affected file lib/silcutil/silcbuffer.h.
1435 * Changed various routines in the core library to use the new
1436 silc_buffer_set instead of allocating new buffer only for
1439 * Added 64-bit value formatting and unformatting support to the
1440 silc_buffer_[un]format routines. Affected file is
1441 lib/silcutil/silcbuffmt.[ch].
1443 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1444 to includes/bitmove.h.
1446 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Fixed channel user mode saving in client library. Affected
1449 file lib/silcclient/command[_reply].c.
1451 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1453 * Defined the file transfer to the SILC Protocol. Added
1454 new packet type SILC_PACKET_FTP and defined File Transfer
1455 Payload. The mandatory file transfer protocol is SFTP
1456 (SSH File Transfer Protocol). Affected file in addition
1457 of the internet draft is lib/silccore/silcpacket.h.
1459 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1460 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1461 is used as part of backup router protocol when the primary
1462 router of the cell is back online and wishes to resume
1463 the position as primary router.
1465 * Redefined the MAC generation keys in the protocol. The
1466 same key is not used anymore in both direction. Both
1467 direction will now use different keys for sending and
1468 receiving. This fixes a potential security flaw. This
1469 change causes incompatibilities in the protocol.
1471 * Redefined also the MAC computation from the packet.
1472 An packet sequence number is now added to the MAC
1473 computation. This prevents possible replay attacks against
1474 the protocol. This change too causes incompatibilities
1477 Added `sequence' field to the SilcPacketContext to hold
1478 the current sequence number for the packet.
1480 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1482 * Added `created' field to the SilcIDListData in the file
1483 silcd/idlist.h to indicate the time when the entry was
1486 * Added `created' field to the SilcChannelEntry too. Affected
1487 file silcd/idlist.h.
1489 * Added `creation_time' aguments to all the announcement functions
1490 in the server. If it is provided then only the entries that
1491 was created after the provided time frame are actually
1492 announced. Affected file silcd/server.[ch].
1494 * The protocol says that the Channel ID's IP address must be
1495 based on the router's IP address. Added check for this in
1496 the silc_server_new_channel when processing incoming New Channel
1497 Payload. Affected file silcd/packet_receive.c.
1499 * Print out the correct version with --version in SILC client.
1500 Affected file irssi/src/silc/core/silc-core.c.
1502 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * Fixed WHOWAS command to check for completnes of the client
1505 entry always, not just when the command is coming from client.
1506 Affected file silcd/command.c.
1508 * Added new function silc_server_packet_queue_purge to purge the
1509 outgoing data queue to the network. After the function returns
1510 it is guaranteed that the outgoing packet queue is empty.
1511 Affected file silcd/packet_send.[ch].
1513 * Purge the outgoing packet queue in the rekey protocol's final
1514 callback to assure that all rekey packets go to the network
1515 before quitting the protocol. Affected file silcd/server.c.
1517 * Added silc_client_packet_queue_parse as similar function as
1518 in server to the client library. The affected file is
1519 lib/silcclient/client.c.
1521 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1523 * Splitted silcd/server.c and created silcd/server_util.[ch]
1524 for utility functions.
1526 * Added new socket flag SILC_SF_DISABLED to indicate that the
1527 connection is open but nothing can be sent to or received from
1528 the connection. Affected file lib/silcutil/silsockconn.[ch].
1529 The checking for disabled socket is checked in the low level
1530 silc_socket_write and silc_socket_read functions.
1532 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1534 * Allow only nicknames and channel names that fits into the
1535 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1537 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1539 * When processing JOIN command reply in server check that if
1540 the channel exists in our global list we'll move it the local
1541 list. Affected file silcd/command_reply.c.
1543 * Fixed the check whether client is joined on the channel already
1544 in JOIN command. Affected file lib/silcclient/command.c.
1546 * Fixed the JOIN command reply to check whether the channel
1547 already exists. Affected file lib/silcclient/command_reply.c.
1549 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Added silc_ske_status_string to map the SKE error numbers
1552 to readable strings. The affected files are
1553 lib/silcske/silcske[_status].[ch].
1555 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1557 * Do not show the private channels on the WHOIS channel list
1558 as it is not allowed by the protocol. The affected file is
1561 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1563 * Assure that the packet length digged from the actual packet
1564 is something sensible in the silc_packet_decrypt_rest_special
1565 in lib/silccrypt/silcpacket.c.
1567 * Free and NULL the allocated pointer in silc_hmac_alloc if
1568 the HMAC allocation fails. The affected file is
1569 lib/silccrypt/silchmac.c.
1571 * Print the selected security properties to the log files in
1572 the server. Affected file silcd/protocol.c.
1574 * Add SKE's reference counter even if calling the completion
1575 callback manually. Otherwise it goes negative, although it
1576 does not cause any problems. The affected file is
1577 lib/silcske/silcske.c.
1579 * Remove the client entry with short timeout after giving the
1580 KILL command. Affected file lib/silcclient/command.c.
1582 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1583 case all found clients are already disconnected (WHOWAS would
1584 found them) in the server. Affected file silcd/command.c.
1586 * Update the last_receive (time of last data received) to be
1587 updated only when received private or channel message so that
1588 the idle time showed in WHOIS makes more sense.
1590 * Added boolean field `valid' in to the SilcClientEntry in the
1591 client library to indicate whether the entry is valid or not.
1592 This fixes the nickname change bug on channel when changing
1593 the nickname to be same than the old (like nick to Nick) the
1594 nickname formatter doesn't set the new nick anymore to Nick@host.
1595 Affected file lib/silcclient/idlist.[ch].
1597 * Now actually fixed the nickname changing on disconnection.
1598 Added new function silc_change_nick to the Irssi SILC Client.
1599 Affected file irssi/src/silc/core/client_ops.c,
1600 irssi/src/silc/core/silc-nicklist.[ch].
1602 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1604 * Check that the public key exists in the GETKEY command before
1605 trying to encode it. Affected file silcd/command.c.
1607 * Print some notifications on received public keys with GETKEY
1608 command in the Irssi SILC Client. Affected files are
1609 irssi/src/fe-common/silc/module-formats.[ch],
1610 irssi/src/silc/core/client_ops.c.
1612 * Use IDENTIFY command to resolve the server information in the
1613 GETKEY command instead of INFO command. Affected file
1614 lib/silcclient/command.c.
1616 * All command reply functions in the client library now calls
1617 the pending command reply callbacks even if an error has
1618 occurred. The server has done this a long time and now it was
1619 time to move the client library to this as well. Now all
1620 errors can be delivered back to the pending command reply
1621 callbacks if necessary. Affected files are
1622 lib/silcclient/command[_reply].[ch].
1624 * Change the nickname on disconnection back to the username
1625 because in reconnect the server will enforce it to it anyway.
1626 Affected file irssi/src/silc/core/silc-servers.c.
1628 * Fixed a config file parsing bug in the Irssi SILC client.
1629 Affected file irssi/src/silc/core/clientconfig.c.
1631 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1633 * When printing the channel mode on JOIN, verify that the
1634 channel key and channel's HMAC are valid. Affected file
1635 irssi/src/silc/core/client_ops.c.
1637 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1639 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1640 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1641 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1643 * Removed channel key rekey task deleting from the function
1644 silc_server_save_channel_key. Affected file silcd/server.c.
1645 Added explicit timeout task context instead that is used to
1646 delete the task if we are registering a new task before the
1647 new task has elapsed.
1649 * When channel key rekey occurs the client library now saves
1650 the old channel key for a short period of time (10 seconds) and
1651 is able to use it in case some is still sending channel
1652 messages encrypted with the old key after the rekey. Affected
1653 file lib/silcclient/[idlist.h|client_channel.c].
1655 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1657 * Added check to the silc_server_new_id_real to not accept
1658 new ID if it is the sender's own ID. Affected file is
1659 silcd/packet_receive.c.
1661 * Assure that we do not announce ourself or the one we've
1662 sending our announcements when we're router and are announcing
1663 servers to our primary router. Affected file silcd/server.c.
1665 * Fixed silc_server_command_identify_check_client to assemble
1666 correct WHOIS packet. It send corrupted WHOIS packet and
1667 caused problem with router to router connections. Affected
1668 file silcd/command.c.
1670 Fixed also silc_server_command_whois_check the same way
1671 as for the IDENTIFY command.
1673 * Added new SilcIDListStatus to the server in the SilcIDListData
1674 structure. The status now includes the current status of
1675 the entry (like registered, resolved etc.). Affected file
1676 silcd/idlist.[ch]. Defined a bunch of different status types
1677 as well. This replaced the old boolean registered field as well.
1679 Added resolve_cmd_ident field to the SilcClientEntry structure
1680 too so that if the entry is for example being resolved so
1681 another command may attach to the same pending command reply
1682 without requiring to resolve the same entry again. This concept
1683 should optimize the WHOIS and the IDENTIFY resolving under
1684 heavy load by taking away unnecessary resolving for entries
1685 that are being resolved already.
1687 Added support for adding multiple pending commands for one
1688 command idenfier. Affected file silcd/command[_reply].[ch].
1690 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1691 before deleting the data. Otherwise the hash table will have
1692 freed data in comparison functions. Affected file is
1693 silcd/command_reply.c.
1695 * Fixed silc_idlist_replace_client_id to add the new entry to
1696 the cache with NULL nickname. Otherwise there will be invalid
1697 memory as the nickname after the nickname is freed. Affected
1698 file silcd/packet_receive.c.
1700 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1701 saved into wrong slots because the previous number of entries
1702 was not taken into account. Affected file silcd/idlist.c.
1703 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1705 * If we are router and we receive JOIN notify to a channel that
1706 does not have any users then notified client is marked as the
1707 channel founder, as it is it. The affected file is
1708 silcd/packet_receive.c
1710 * Added to the extended hash table API's table_del_*ext functions
1711 the destructor as argument too, so that the caller can decide
1712 which destructor to use or whether to use destructor at all.
1713 Affected file lib/silcutil/silchashtable.[ch].
1715 * Fixed ID Cache purging. It actually deleted the entries from
1716 the hash table after the data was freed. The hash table ended
1717 up comparing freed memory. The affected file is
1718 lib/silccore/silcidcache.c.
1720 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1722 * Fixed Irssi SILC client's KILL command's HELP syntax.
1724 * The USERS command now resolves the detailed user information
1725 if the userinfo field is missing. Affected file is
1726 lib/silcclient/command_reply.c.
1728 * Do not print error in silc_file_read if the read file does
1729 not exist. Just silently return NULL. Affected file is
1730 lib/silcutil/silcutil.c.
1732 * Fixed the silc_log_output to not wine about NULL filename
1733 and to not create some bogus " " filename. Affected file is
1734 lib/silcutil/silclog.c.
1736 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Fixed various printing bugs on the user interface in the
1739 Irssi SILC Client. Minor changes that were forgotten from
1742 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1744 * Fixed the configure.in.pre and the compilation and distribution
1745 environment to support the new autoconf 2.52. That version is
1746 now required to compile the CVS trunk.
1748 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1750 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1751 to generally parse user@fqdn format strings. Affected file
1752 lib/silcutil/silcutil.c.
1754 * Added nickname_format and nickname_force_format fields to the
1755 SilcClientParams structure. The first one defines the format
1756 for the nicknames that the library will enforce if the receives
1757 multiple same nicknames. The second one is boolean value and
1758 can be used to force the library to always enforce the format
1759 to the nicknames regardles whether there are multiple nicknames
1760 or not. This configurable formatting was employed to flexibly
1761 support accessing multiple nicknames from the user interface.
1762 The userinterface can now set the nicknames to what ever format
1763 they prefer. Affected file lib/silcclient/silcapi.h.
1765 Added function silc_client_nickname_format to the file
1766 lib/silcclient/idlist.c. It performs the nickname formatting.
1768 Added new field `hostname´ to the SilcClientEntry context.
1769 It holds the hostname of the client. Affected file is
1770 lib/silcclient/idlist.h.
1772 * Irssi SILC Client sets the nicknames in nick@hostn format.
1773 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1774 irssi/src/silc/core/silc-core.c.
1776 The WHOIS printing now also shows both the real nickname and
1777 the formatted nickname so that user knows how to access the
1778 user if there are multiple same nicknames cached. Affected
1779 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1780 printing formatting too to take the hostname now as a separate
1781 argument. The Affected file is
1782 irssi/src/fe-common/silc/modules-formats.[ch].
1784 * Changed the silc_client_get_clients_local to accept the formatted
1785 nickname as argument. It accepts the real nickname too but the
1786 formatted nickname can be used to find the true entry from
1787 multiple entries. Affected file lib/silcclient/silcapi.h and
1788 lib/silcclient/idlist.c.
1790 * Added nickname_format_parse field to the SilcClientParams.
1791 It is a callback function provided by the application to parse
1792 the nickname out of the formatted nickname string. The library
1793 calls it to get the nickname from the formatted string. Since
1794 the application generally knows better the format of the nickname
1795 string it parses it instead of the library, even though library
1796 encodes the formatted string. If the callback function is not
1797 provided then the library will use the string as is. The
1798 affected file is lib/silcclient/silcapi.h.
1800 * All the nickname strings passed to the client library in
1801 commands are now expected to be formatted nickname strings.
1802 If the command does not support the formatted nickname string
1803 it will assume that the sent string is the actual nickname.
1804 Affected file lib/silcclient/command.c.
1806 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Added public key authentication support to OPER and SILCOPER
1809 commands in the client library. Affected file is
1810 lib/silcclient/command.c.
1812 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * Changed the get_auth_methdod client operation to be asynchronous.
1815 It can be async if the application resolves the authentication
1816 method from the server during the negotiation. Added new
1817 SilcGetAuthMeth completion callback that the application will
1818 call after resolving the authentication method.
1820 Added function silc_client_request_authentication_method that
1821 the application can use to resolve the authentication method
1822 from the server. Added also SilcConnectionAuthRequest callback
1823 that the library will call after the server has replied. The
1824 application can call this function if it does not know the
1825 current authentication method.
1827 Affected files are lib/silcclient/client.c and
1828 lib/silcclient/silcapi.h.
1830 * The Irssi SILC client now automatically resolves the authentication
1831 method incase any configuration information is not present (and
1832 currently there never is). The affected file is
1833 irssi/src/silc/core/client_ops.c.
1835 * Fixed public key authentication from the client library.
1836 Affected file lib/silcclient/protocol.c. Changed also the
1837 protocol specification about the public key authentication in
1838 the connection authentication protocol. The actual data to be
1839 signed is now computed with a hash function before signing.
1841 * Fixed the public key authentication from the server as well.
1842 Affected file silcd/protocol.c.
1844 * Removed the mlock()'s from the memory allocation routines.
1845 Affected file lib/silcutil/silcmemory.c. The ./configure does
1846 not check anymore for the mlock(). Affected file is
1849 * Fixed USERS command in server to allow the execution of the
1850 command for private and secret channels if the client sending
1851 the command is on the channel. Affected file silcd/command.c.
1853 * Fixed silc_client_get_clients_local to return the clients
1854 count correctly. It could return wrong value. Affected file
1855 lib/silcclient/idlist.c.
1857 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1859 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1860 types. The assembler optimizations seemed not to like 64-bit
1861 data types. The assmebler optimizations thus are now enabled
1862 also for BSD systems as opposed to only enable them for Linux.
1864 * Do not check for threads at all on BSD systems. Affected
1865 file configure.in.pre.
1867 * Removed -n and -h options from the Irssi SILC Client since
1868 they are not used in silc.
1870 * Fixed the prime generation to assure that the first digit
1871 of the generated random number is not zero since our conversion
1872 routines does not like number strings that starts with zero
1873 digit. If zero digit is seen the random number is regenerated.
1874 This caused some corrupted RSA keys when the zero first digit
1875 was met. Affected file lib/silcmath/silcprimegen.c.
1877 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1879 * Fixed WIN32 configuration in the ./configure script.
1880 Fixed to include xti.h on environments that has it.
1881 Patches by Carsten Ilchmann and andrew.
1883 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1885 * Changed the silc_id_create_client_id to be collision
1886 resistant. It is now assured that there cannot be created
1887 two same client ID's. I suspect that some weird bugs in
1888 the server were actually caused by duplicate Client IDs.
1889 Affected file silcd/serverid.[ch]. A router receiving
1890 new ID now also assures and informs the sending server
1891 if the ID caused collision.
1893 * Changed the silc_id_create_channel_id to also assure that
1894 there are no collisions.
1896 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * Statement about ignoring the Mutual Authentication flag when
1899 performing rekey with PFS was a bit misleading. It is ignored
1900 if it was set in the initial negotiation, it cannot be even
1901 set in the rekey. Fixed in the ke-auth draft. Started the
1902 new versions of the protocol drafts in the doc/.
1904 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1906 * Fixed a bug in silc_client_command_identify_save when saving
1907 new channel information. The channel name was no duplicated
1908 and caused crash on exit. Affected file is
1909 lib/silcclient/command_reply.c.
1911 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Fixed the getkey command handling in the server. Send just
1914 empty OK reply to the sender if the key could not be fetched
1915 (but everything else was ok, like the key just was not available).
1916 Changed the public key parameter to optional in the protocol
1917 specs so that empty OK reply can be sent. Affected file
1920 Added a message to Irssi SILC client to tell to user if the
1921 server did not return a public key.
1923 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Fixed a channel key regeneration bug. It registered new
1926 timeout tasks exponentially until all system resources were
1927 used. Affected file silcd/server.c.
1929 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Added the SILC Document generator to the scripts/silcdoc.
1932 It can be used to generate the Toolkit Reference Manual out
1933 of the source tree. Internally it will also use the RoboDoc
1934 generator now imported in util/robodoc.
1936 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Added couple of return's in rekey protocol if error orccurred
1939 during the protocol. The execution must be terminated.
1940 Affected file silcd/protocol.c. Also, terminate the protocol
1941 always with timeout.
1943 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1945 * The client's Client ID was created initally from the wrong
1946 nickname (it could have been in format nick@host) in the
1947 silc_server_new_client. Affected file silcd/packet_receive.c
1949 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1951 * Added some SILC_LOG_ERROR's to various error conditions
1952 if client could not be added to ID cache. Affected files
1953 silcd/packet_receive.c and silcd/server.c.
1955 * When client's sock->user_data is freed, NULL also the
1956 client->router and client->connection pointers. Added check
1957 for these pointers being NULL to various places around the
1958 code. Affected file silcd/server.c.
1960 * Added client->data.registered == TRUE checks to various
1961 places around the code to assure that unregistered client's
1962 are not handled when it is not allowed. Affected file
1965 * Added `bool registered' fields to all
1966 silc_idlist_[server|client]_get_* routines to indicate whether
1967 the fetched client needs to be registered or not. Affected
1968 file silcd/idlist.[ch].
1970 * Add your own entry as registered to the ID cache in the
1971 server. Affected file server.c.
1973 * Fixed a bug in silc_server_new_server. The SilcServer was
1974 set as the new server's context instead of SilcServerEntry.
1975 This naturally caused some weird bugs.
1977 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Do not delete the channel rekey task when adding it
1980 for in silc_server_create_channel_key.
1982 * Changed the silc_server_create_channel_key to return
1983 TRUE or FALSE to indicate the success of the channel key
1986 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Fixed MSVC++ project files and added missing files to
1989 Makefiles under win32/.
1991 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Do not add TCP_NODELAY flag if the operating system
1994 does not have it defined. Affected files are
1995 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1997 * Fixed buffer overflow from Irssi SILC Client. Affected
1998 file irssi/src/fe-common/core/themes.c.
2000 * Fixed double free in client library in the file
2001 lib/silcclient/client.c when disconnecting from server.
2003 * Applied double free patch from cras to Irssi SILC client.
2004 Affected files irssi/src/core/[modules/expandos].c
2006 * Fixed the disconnection handling to Irssi SILC Client.
2007 The application must call silc_client_close_connection
2008 in ops->connect client operation in case of failure of
2009 the connection. Affected file is
2010 irssi/src/silc/core/client_ops.c.
2012 * Do not set sock->protocol to NULL in the function
2013 silc_client_close_connection after executing the protocol's
2014 final callback since the sock might not be valid anymore.
2015 Affected file lib/silcclient/client.c.
2017 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * Do not enable SILC_THREADS if the linking with libpthread
2020 did not happen. Affected file configure.in.pre.
2022 * Added notion to protocol specification that server must
2023 verify the sent authentication payload with CMODE when
2024 setting the channel founder key. Implemented it to the
2025 server. Affected file silcd/command.c.
2027 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2029 * Added _EXTRA_DIST SILC distribution variable to the
2030 distributions file. It is used to conditionally add extra
2031 files or directories to the specific distribution. Affected
2032 files ./prepare, Makefile.am.pre and distributions.
2034 Removed the `_' from the start of the distribution names.
2037 * Added README.WIN32 for instructions to compile the Toolkit
2040 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2042 * Fixed a double free in disconnection in the server. Affected
2043 file is silcd/server.c.
2045 * Fixed the lib/silcske/groups.c to work now also with GMP
2046 MP library. The string conversion did not work when using
2047 specific base and the base is indicated in the string as well.
2049 * Created win32/ directory which now includes MSVC++ specific
2050 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2051 It will appear only in the toolkit distribution
2053 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * Changed the key material distribution function in case when
2056 the hash output is too short. The data is now concatenated
2057 a bit differently than it used to. Made the change to the
2058 SKE protocol specification.
2060 * Added better GMP detection to configure.in.pre. A patch
2063 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Fixed a minor bug in SKE that might cause some problem on
2066 some platforms. Affected file lib/silcske/silcske.c.
2068 * Added the cookie checking for initiator in the SKE. It checks
2069 that the responder returns the sent cookie unmodified. The
2070 affected file is lib/silcske/silcske.c. Added new SKE
2071 error type INVALID_COOKIE that can be sent during the
2072 negotiation. Fixed some memory leaks as well.
2074 * Added the "invalid cookie" error message to Irssi SILC client's
2077 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Added `task_max' field to the SilcClientParams to indicate
2080 the maximum tasks the scheduler can handle. If set to zero,
2081 default values are used. Affected file lib/silcclient/silcapi.h.
2083 * Fixed memory leaks in silc_client_close_connection. Affected
2084 file lib/silcclient/client.c.
2086 * Added silc_client_del_client_entry to client library to free
2087 all memory of given client entry. Affected file is
2088 lib/silcclient/idlist.[ch].
2090 * Added new functions silc_client_del_channel and
2091 silc_client_del_server to delete channel and server entries.
2092 Affected file lib/silcclient/[silcapi.h/idlist.c].
2094 * Removed silc_client_del_client_by_id from silcapi.h.
2096 * Fixed the INFO command to return the server's own info
2097 correctly when querying by Server ID. Affected file is
2100 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Removed the non-blocking settings in WIN32 code in the
2103 silc_sock_[read/write] and added SleepEx instead. Affected
2104 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2105 of input data is now checked with FIONREAD and ioctlsocket.
2107 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Call silc_schedule_task_del_by_context in the
2110 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2111 Affected file lib/silccore/silcprotocol.c.
2113 * Call silc_protocol_cancel for active protocols in the
2114 silc_server_close_connection if the funtion
2115 silc_server_free_sock_user_data has not been called.
2116 Affected file silcd/server.c.
2118 * Generic tasks cannot be deleted using the del_by_fd
2119 task deleting function since generic tasks does not match
2120 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2122 * Added a notion to SILCOPER help file that the SILCOPER works
2123 only on router server, not on normal server.
2125 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2127 * Added for WIN32 support for the new scheduler as well.
2128 Affected file lib/silcutil/win32/silcwin32schedule.c.
2130 * Fixed the SHA1 implementation to work on various platforms.
2132 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2135 API. It is part of the scheduler now. Everything else is
2136 as previously but some functions has changed their names.
2137 Checkout the lib/silcutil/silcschedule.h for the interface.
2138 Updated all applications to use the new interface. Affected
2139 files are lib/silcutil/silcschedule.[ch].
2141 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Found a bug in the SKE implementation. The HASH value,
2144 specified by the protocol, was not computed correctly. The
2145 public key of the responder was not added to the computation
2146 even though it is mandatory. Affected file lib/silcske/silcske.c.
2147 This unfortunately causes incompatibilities with older
2148 clients and servers.
2150 * Added WIN32 specific network init and uninit functions:
2151 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2152 the Winsock2. Affected file lib/silcutil/silcnet.h and
2153 lib/silcutil/win32/silcwin32net.c.
2155 * Set the socket always to nonblocking mode on WIN32 after
2156 reading data or writing data. Affected file is
2157 lib/silcutil/win32/silcwin32sockconn.c.
2159 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Fixed various compilation problems under WIN32. Affected
2162 files lib/silcutil/win32/silcwin32thread.c and
2163 lib/silcutil/win32/silcwin32schedule.c.
2165 * Removed all _internal.h #includes from public header
2166 files. Internal headers must never be included from
2169 Removed also the lib/silcske/payload_internal.h file.
2171 * All include files that may be needed (public and some others
2172 included by the public headers) by application developers are
2173 now copied to the ./includes directory. It does not copy any
2174 internal headers. Affected file Makefile.defines.pre and all
2175 Makefile.am's under lib/ and subdirs.
2177 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Do not change the ~/.silc directory's permissions automatically.
2180 Affected file irssi/src/silc/core/clientutil.c.
2182 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Do not cancel the protocol in silc_server_close_connection
2185 it might cause recursion. Now cancelled in the function
2186 silc_server_free_sock_user_data. Affected file silcd/server.c.
2188 * Fixed the silc_server_remove_clients_by_server to regenerate
2189 the channel keys correctly finally. Added also new function
2190 silc_server_remove_clients_channels to actually do it.
2191 Affected file silcd/server.c.
2193 * Fixed the silc_server_new_channel to not crash by giving
2194 wrong router to the new channel. Affected file is
2195 silcd/packet_receive.c.
2197 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2199 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2200 which is given as argument to the silc_client_alloc now.
2201 It can be used to configure the client and set various parameters
2202 that affect the function of the client.
2204 * The USERS command in server did not check whether the channel
2205 is private or secret. Affected file silcd/command.c.
2207 * Added new argument to the USERS command in protocol specification.
2208 The USERS command now can take the channel name as argument
2209 as well. Added support for this in client and server and
2210 updated the protocol specs.
2212 * Completed the GETKEY command in client. It can be now used
2213 to fetch also servers public key not only some clients.
2214 Affected files lib/silcclient/command[_reply].c.
2216 * Added silc_client_get_server to return server entry by the
2217 server name. Affected files lib/silcclient/silcapi.h and
2220 * Redefined the IDENTIFY command in protocol specification to be
2221 more generic. It now can be used to query information about
2222 any entity in the SILC Network, including clients, servers and
2223 channels. The query may be based either the entity's name
2224 or the ID. Added support for this in both client and server.
2226 Affected files silcd/command.c and lib/silcclient/command.c
2227 and command_reply.c.
2229 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2230 the _from_client and _from_server functions. Affected file
2233 * Added silc_client_get_channel_by_id_resolve to the file
2234 lib/silcclient/silcapi.h to resolve channel information by
2235 its ID. Added also silc_client_get_channel_by_id that
2236 does not resolve it from the server.
2238 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Added SilcServerEntry context into the client library
2241 to represent one server. The INFO command now allocates
2242 these to save the resolved server info. For now on the
2243 client library will also keep information about servers,
2244 connected and resolved with INFO.
2246 The INFO command now allocates the SilcServerEntry context
2247 and saves the server info there. The COMMAND_REPLY in
2248 the INFO now returns the parameters to application in
2249 same order as defined in the protocol specification.
2251 The entries are cached in the client->server_cache.
2253 * The INFO command is now issued after received the Client ID
2254 from the server. Affected file lib/silcclient/client.c.
2256 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2257 to the application as the mode changer might be server.
2258 It is guaranteed that NULL is not returned anymore to the
2259 application. Affected file lib/silcclient/client_notify.c.
2261 The ID Type is now also passed to the application so that
2262 it can check whether the returned entry is SilcClientEntry
2265 Added new function silc_client_get_server_by_id to return
2266 the server entry by ID. Affected files are the
2267 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2269 * Do not create the channel in the Irssi SILC Client when issuing
2270 the JOIN command but when received the sucessful JOIN command
2271 reply. Otherwise the channel might get created even though we
2272 could not join it. The Affected file is
2273 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2275 * Fixed a channel joining bug in router. The router must also
2276 check the channel modes, invite and ban lists etc. when serving
2277 the JOIN command sent by normal server. Affected file is
2278 silcd/command.c. The router now resolves the client's
2279 information from the server who sent the JOIN command if it
2280 does not know it, and processes the JOIN command only after
2283 * Changed the SilcCommandCb to take new argument; void *context2.
2284 Affected file lib/silccore/silccommand.h
2286 The second argument in the command callbacks in the server now
2287 includes the SilcServerCommandReplyContext if the command was
2288 called as pending command callback from the command reply.
2289 Otherwise it is NULL. When called as pending the status of the
2290 command reply will be checked and if it was erronous the
2291 error will be sent to the original sender of the command.
2292 This way the client always receives the error messages even
2293 though the server was actually the one who received the error
2294 when it resent the command to router, for example. Affected
2295 files silcd/command[_reply].[ch].
2297 * Fixed sending WHOWAS command's error message to client if
2298 the requested client could not be found. It was missing.
2301 * Changed the CMODE and CUMODE commands reply arguments in the
2302 protocol specification. The Channel ID is now sent in both
2303 of the commands to identify the channel. Implemented this
2304 new feature to the client and server. Affected files
2305 lib/silcclient/command_reply.c and silcd/command.c.
2307 * Made better checks for invite and ban lists in the JOIN
2308 command in server. Affected file silcd/command.c.
2310 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * The server now performs the incoming host IP/DNS lookup
2313 using the silc_socket_host_lookup and thus does not block
2314 the server anymore. Affected file silcd/server.c.
2316 * Completed the multi-thread support for SILC Scheduler in
2317 the lib/silcutil/silcschedule.c.
2319 * Fixed the configure.in.pre to detect the pthread correctly
2322 * Fixed a deadlock in silc_task_queue_wakeup in the file
2323 lib/silcutil/silctask.c.
2325 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2327 * Added new function silc_schedule_wakeup that is used in
2328 multi-threaded environment to wakeup the main thread's
2329 schduler. It needs to be used when a thread adds a new task
2330 or removes a task from task queues. After waking up, the
2331 scheduler will detect the task queue changes. If threads
2332 support is not compiled in this function has no effect.
2333 Implemented the wakeup mechanism to both Unix and WIN32
2334 systems. Affected files are lib/silcutil/silcschedule.[ch],
2335 lib/silcutil/unix/silcunixschedule.c and the
2336 lib/silcutil/win32/silcwin32schedule.c.
2338 * Added new function silc_task_queue_wakeup to wakeup the
2339 scheduler by the specified task queue. Affected file
2340 lib/silcutil/silctask.[ch].
2342 * The silc_socket_host_lookup_start now wakes up the scheduler
2343 after adding the timeout task. Affected file is
2344 lib/silcutil/silcsockconn.c.
2346 * The silc_socket_host_lookup is synchronous now if the threads
2347 support is not compiled in. However, the callback is still
2348 called asyncronously through the scheduler, anyway. Affected
2349 file lib/silcutil/silcsockconn.c.
2351 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Added new function silc_socket_host_lookup to perform
2354 asynchronous IP and FQDN lookups for the socket connection.
2355 Affected files lib/silcutil/silcsockconn.[ch].
2357 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2360 that may or may not compile the mutex support in.
2362 Changed the silc_mutex_alloc interface. It allocates the
2363 mutex now to the sent pointer and returns TRUE or FALSE.
2365 Affected file lib/silcutil/silcmutex.h.
2367 * Wrote the SILC Task Queue interface to support multi-threads.
2368 Affected file lib/silcutil/silctask.[ch].
2370 * Wrote the SILC Scheduler to support multi-threads. Affected
2371 file lib/silcutil/silcschedule.c.
2373 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2376 in lib/silcutil/win32/.
2378 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2380 * Defined SILC Mutex API and SILC Thread API and implemented
2381 them for Unix. Affected files are
2382 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2383 lib/silcutil/unix/silcunixmutex.c and
2384 lib/silcutil/unix/silcunixthread.c.
2386 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2388 * Fixed the silc_server_remove_clients_by_server's channel
2389 key re-generation. The hash table handling was incorrect
2390 and would not work with many channels. Affected file is
2393 * Fixed some memory leaks around the server code.
2395 * Rewrote the silc_server_get_users_on_channel to support IPv6
2396 based Client ID's. Affected file silcd/server.c.
2398 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2399 specification. However, a separate document must be written
2400 to define the detailed signing procedure and the payload
2401 associated with the flag. Defined the flag to the
2402 lib/silccore/silcchannel.h as well.
2404 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2406 * Changed the dynamic tables to static size tables in the
2407 lib/silccrypt/silchmac.c.
2409 * Removed GCC dependencies from the code. A patch by cras.
2411 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Do not show the error "Error receiving packet bla bla"
2414 in server if it really was not an error (-2 means that reading
2415 is pending). Affected file silcd/server.c.
2417 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Fixed a possible crash in silc_server_remove_clients_by_server
2420 in silcd/server.c. Fixed there also some memory leaks.
2422 * Fixed the silc_idlist_replace_client_id. It could replace
2423 wrong key in the hash table. Affected file silcd/idlist.c.
2425 * Do not check whether there are global users on the channel
2426 if the channel->global_users is FALSE. Affected functions
2427 silc_server_remove_from_one_channel and
2428 silc_server_remove_from_channels in silcd/server.c. Also,
2429 do not check if the removed client is local as we can be
2430 sure that global client was not removed from the channel
2431 and checking for global users is not needed.
2433 * The silc_server_remove_clients_by_server now re-generates
2434 the channel keys correctly for those channels that had
2435 clients removed from them. Affected file silcd/server.c.
2437 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2439 * Found the reason of random crashes in the server. We weren't
2440 ignoring the SIGPIPE signal (which can be sent in write())
2441 and it crashed the server. Affected file silcd/silcd.c.
2443 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * Assure that sock->user_data is not NULL in the function
2446 silc_server_packet_send in silcd/packet_send.c.
2448 * Disconnect the remote connection if it could not be added
2449 to any ID lists in the server. The affected file is
2452 * Check in silc_server_packet_send[_real/dest] that the
2453 socket is not disconnecting and ignore the data if it is.
2454 Affected file silcd/packet_send.c.
2456 * Define inline to __inline on native WIN32 compilation.
2457 Affected file includes/silcwin32.h.
2459 * Added some explicit type casts for inline code since MSVC
2460 require them. Affected files lib/silcutil/silcbuffer.h,
2461 lib/trq/silcdlist.h and lib/trq/silclist.h.
2463 * Print warning in log files from now on if the packet
2464 decryption fails. Affected file silcd/server.c.
2466 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Changed the `say' client operation's interface to accept
2469 new `type' argument to indicate the type of the message sent
2470 by the library. The application may filter the library's
2471 messages according the type. The affected file is the
2472 lib/silcclient/silcapi.h.
2474 * Added two new functions to lib/silcclient/silcapi.h:
2475 silc_client_del_client and silc_client_del_client_by_id.
2476 Affected file lib/silcclient/idlist.c.
2478 * Moved the clientincludes.h from includes/ to silc/ and
2479 serverincludes.h from includes/ to silcd/.
2481 * The modes for the CMODE and CUMODE are now passed as
2482 uint32 for application with COMMAND_REPLY. The affected
2483 file is lib/silcclient/command_reply.c.
2485 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * /WHOIS without arguments shows client's own information.
2488 Affected file lib/silcclient/command.c.
2490 * Changed PING to not accept any arguments. The specs
2491 says that client can ping only the connected server so
2492 requiring an argument is not needed. Affected file is
2493 lib/silcclient/command.c.
2495 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Fixed a fatal bug in private message sending and reception
2498 encryption and decryption when using private message keys.
2499 The implementation was incorrect and did not follow the
2500 specification. It causd that some of the message were
2501 lost since it did not use the sending and receiving keys
2502 as the protocol suggests. This has been fixed and will cause
2503 incompatibilities with older clients when sending private
2504 message encrypted with private message keys. Affected files
2505 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2506 and various other in Irssi SILC Client.
2508 Added `responder' boolean argument to the functions
2509 silc_client_add_private_message_key[_ske] to indicate when
2510 the key is added as responder or initiator of the key
2513 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * Removed the silc_ske_check_version function and created
2516 a SilcSKECheckVersion callback. Added also a function
2517 silc_ske_set_callbacks that is now used to set all SKE
2518 callbacks. The callback functions are not given to
2519 the SKE functions anymore, but this function is used to
2522 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2524 * Added `silc_version' argument to the silc_client_alloc
2525 to define the version of the application for the library.
2526 The library will use the version string to compare it
2527 against the remote host's (usually a server) version
2528 string. Affected file lib/silcclient/silcapi.h
2530 * Added the KE protocol context to Key Agreement context
2531 in client library so that we can abort the SKE if it
2532 is in process when we get timeout. Affected file is
2533 lib/silcclient/client_keyagr.c.
2535 * Do not resolve the client ID forever if it returns in the
2536 first time that such client does not exist. This was done
2537 for example with private message. Affected file is
2538 lib/silcclient/client_prvmsg.c.
2540 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2542 * Do not add regex.h for WIN32. The affected file
2543 includes/silcincludes.h.
2545 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2546 not work yet 100%. It generates the DLL's automatically
2547 when compiling with --with-win32 under cygwin.
2549 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * lib/contrib/regex.c is not compiled on WIN32.
2553 * Added silc_net_get_socket_opt function to the
2554 lib/silcutil/silcnet.h.
2556 * Added includes/silcwin32.h for WIN32 specific includes
2559 * Do not use ptime structure or any of the posix process
2560 functions on WIN32 in lib/silccrypt/silrng.c.
2562 * Added silc_gettimeofday to provide generic function
2563 for struct timeval on all platforms. Added the function
2564 to lib/silcutil/silcutil.h.
2566 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2569 library as they clearly belong there. As a plus side we
2570 can make the actual socket connection routines platform
2573 Added also new generic function silc_socket_read and
2574 silc_socket_write (that used to be silc_packet_[read/write].
2575 The implementation of these are platform specific.
2577 * Added WIN32 specific routines of silc_socket_[read/write]
2578 to lib/silcutil/win32/silcwin32sockconn.c.
2580 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Added preliminary support for native WIN32 compilation under
2583 cygwin (using the -mno-cygwin option for GCC) to the
2584 ./configure.in.pre. The --with-win32 now prepares the
2585 compilation for native WIN32.
2587 * Rewrote the SILC Scheduler interface in the file
2588 lib/silcutil/silcschedule.h. The scheduler is now context
2589 based and does not have anymore any global static scheduler.
2590 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2591 and created lib/silcutil/win32 directory for WIN32 based
2594 * Added Unix specific network routines to the
2595 lib/silcutil/unix/silcunixnet.c and the old
2596 lib/silcutil/silcnet.c includes now only generic routines.
2598 Added WIN32 specific network routines to the
2599 lib/silcutil/win32/silcwin32net.c.
2601 * Added Unix specific utility functions from the
2602 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2604 * Added WIN32 SILC Scheduler to the file
2605 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2608 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2610 * Do not handle JOIN notify in the server if the target client
2611 is not registered (idata->registered == FALSE). The affected
2612 file is silcd/packet_receive.c.
2614 * Update the nickrec->founder in event_cumode in the Irssi SILC
2615 client. Affected file irssi/src/silc/core/silc-channels.c.
2617 * Fixed the CUMODE_CHANGE notify handling in the server when
2618 server and router are announcing their clients on channels.
2619 Now the mode changes are saved and notified correctly. The
2620 affected file is /silcd/packet_receive.c.
2622 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2623 They really did not replace the cache entry in the ID Cache.
2624 Now they do that. Affected file silcd/idlist.c.
2626 * Fixed the KICK notify handling in the Irssi SILC client to
2627 update the channel records so that the kicked client does not
2628 appear to be on the channel. The affected file is
2629 irssi/src/silc/core/silc-channels.c.
2631 * Always update the conn->current_channel when executing command
2632 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2634 * Fixed the KILL notify handling in Irssi SILC client to remove
2635 the killed client on all channels.
2637 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Fixed the silc_parse_command_line to remove extra spaces
2640 from the start and end of the arguments. Affected file is
2641 lib/silcutil/silcutil.c.
2643 * Cancel and free any active protocol in the function
2644 silc_server_close_connection. Affected file silcd/server.c.
2646 * Cancel and free any active protocol in the function
2647 silc_client_close_connction. Affected file is
2648 lib/silcclient/client.c.
2650 * Do not execute the KILL command for clients that are in
2651 history (ie. they are not in the network). Affected file is
2654 * Fixed KILL notify handling, client does not crash anymore.
2655 Affected file irssi/src/silc/core/silc-channels.c.
2657 * Reduced the default packet buffer size from 2048 to 1024 in
2658 lib/silccore/silcpacket.c.
2660 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2661 counter to the SKE context that is incresed when the SKE library
2662 performs async operation outside the library. If the outside
2663 process frees the SKE context and FREED status will be set
2664 and the library will detect after the sync operation that the
2665 libary is freed. The affected files are
2666 lib/silcske/silcske[_status].[ch].
2668 * Resolve the client entry information in the function
2669 silc_client_channel_message to assure that NULL pointer is not
2670 passed as client entry to the application. */
2672 * Fixed the task timeout calculation to assure that there is
2673 never negative timeouts. The affected file is
2674 lib/silcutil/silcschedule.c.
2676 * Fixed the channel user mode notification sending in server.
2677 It was sent point-to-point to the router (or to server by router)
2678 but it needs to be destined to a channel. The routines now
2679 supports sending the channel user mode notifys to the channels
2680 when announcing clients and channels. Affected files are
2681 silcd/server.c and silcd/packet_receive.c.
2683 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2684 It did not actually replace the old channel entry in the cache.
2685 Affected file lib/silcclient/client_notify.c.
2687 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Fixed a possible crash in silc_packet_send_prepare. It now
2690 assures always that there is enough space in the buffer and
2691 at the tail area of the buffer (for MAC).
2693 Fixed the inbound buffer reallocation in silc_packet_read.
2694 It was old code and did not handle the reallocation correctly.
2697 The affected file is lib/silccore/silcpacket.c.
2699 * Fixed buffer overflow in silc_parse_nickname in the file
2700 lib/silcutil/silcutil.c.
2702 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2704 * make install generates new server keys only if there is not
2707 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2709 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2710 Added check that if the NOREPLY is set then we will not send
2711 the away message. This avoids infinite loop of away messages
2712 if both clients are away. The affected file is
2713 lib/silcclient/client_prvmsg.c.
2715 * Fixed client crash if /NICK was given without arguments.
2716 Affected file lib/silcclient/command.c.
2718 * Server does not send the invite list in INVITE command back
2719 to the client if the list was not altered. Added this notion
2720 to the protocol spec as well. Affected file silcd/command.c.
2722 Fixed possible crash in INVITE command by checking the
2723 value of silc_server_get_client_route command.
2725 * Fixed the INVITE notify type handling. The arguments are now
2726 taken in correct order and client does not crash. The affected
2727 file is irssi/src/silc/core/silc-channels.c.
2729 Removed the "Inviting xxx to channel" message from the
2730 client library away and let the application handle it.
2731 Affected file lib/silcclient/command.c. Added that message
2732 to Irssi SILC client's message formats.
2734 * Fixed CMODE command crash in client. It now checks the
2735 amount of arguments correctly and does not crash. The affected
2736 file is lib/silcclient/command.c.
2738 * Do not create new channel automatically in silc_channels_join
2739 but check whether the channel by that name already exists.
2740 Affected file irssi/silc/core/silc-channels.c.
2742 * Do not send the SERVER_SIGNOFF to router if the disconnected
2743 entity was the router. Affected file silcd/server.c.
2745 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2746 SILC client as it was missing from there.
2748 Added the handling of the KICK notify to the Irssi SILC client
2749 as it was missing. Added "you have been kicked" message to
2750 Irssi SILC client's message modules formats.
2752 Added the handing of the KILL notify to the Irssi SILC client
2753 as it was missing. Added the kill message module formats
2756 The affected file is irssi/src/silc/core/silc-channels.c.
2758 * The router did not save the channel mode the server announced.
2759 Affected file silcd/packet_receive.c.
2761 * Fixed a possible crash in INFO command in server. If the
2762 server did not provide the server info it crashed. Affected
2763 file silcd/command.c.
2765 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2767 * Fixed the GETKEY command in the server to check also the
2768 global list. Otherwise the GETKEY would not work correctly
2769 in normal SILC server. Affected file silcd/command.c.
2771 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2773 * Fixed GETKEY crash, it crashed if the command did not succseed.
2775 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2777 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2778 is now real and not just an macro interface to GMP.
2780 Removed the entire GMP from the source tree and imported new
2781 NSS MPI library instead. Reason for removing GMP is that it is
2782 extremely large and compiles extremely slow. The NSS MPI
2783 is only a few files and compiles in less than 10 seconds.
2784 The speed is also about the same as GMP. The MPI is imported
2785 to lib/silcmath/mpi.
2787 If the system has GMP installed we will still use the GMP.
2788 If it is not then the NSS MPI will be compiled.
2790 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Merged a long nickname (127 characters long) crash bugfix from
2793 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2795 * Merged a freed memory reference bugfix from Irssi CVS tree.
2796 Affected file irssi/src/core/commands.c.
2798 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Added the server's public key sving and verification to the
2801 server when performing the SKE. This was missing and the
2802 remote server's (or router's) public key was accepted without
2803 checking whether we have it previously or trust it at all.
2804 Affected file silcd/protocol.c.
2806 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2808 * Check in the silc_server_timeout_remote if protocol is active
2809 and make sure that the protocol's final callback is called so
2810 that all memory if freed. Affected file silcd/server.c.
2812 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * silc_server_whois_send_reply crashed the server if the nickname
2815 was 127 characters long. Affected file silcd/command.c.
2817 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2819 * Added sanity check to the silc_server_new_client. If the hostname
2820 is provided inside username then check that the provided hostname
2821 really is the same as the resolved one. If the hostname was not
2822 resolved then check it from the public key. Affected file is
2823 silcd/packet_receive.c.
2825 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2826 if the server disconnected us and the connection is not valid
2827 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2829 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2830 the library to the lib/silcutil/silcutil.[ch].
2832 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Close log file after open. Affected file
2835 lib/silcutil/silclog.c.
2837 * Check whether sock == NULL in silc_client_send_packet and return
2838 if it is. Affected file lib/silcclient/silcclient.c.
2840 * Check rec->entry == NULL in the Irssi SILC Client before
2841 sending the channel message. Affecte file is
2842 irssi/src/silc/core/silc-servers.c.
2844 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2846 * Merged a splitted window bugfix from Irssi CVS tree. The
2847 affected file is irssi/src/fe-text/textbuffer-view.c.
2849 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2850 It did not print nickname.
2852 * Improved the distributions system a bit.
2854 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2857 irssi/src/fe-text/gui-window.c.
2859 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2860 to in-active server. The affected file is
2861 irssi/src/silc/core/client_ops.c.
2863 * Resolve the client in USERS command reply if the entry does
2864 not have username resolved. The affected file is
2865 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2866 command to WHOIS command to really resolve stuff. The USERS
2867 is not used any more in any critical section so WHOIS can
2868 be used even though it might be slower than IDENTIFY.
2870 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2873 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * Changed the protocol API a bit more consistent in the
2876 lib/silccore/silcprotocol.[ch].
2878 * Changed the following headers to ROBODoc format:
2880 lib/silccore/silcpayload.h
2881 lib/silccore/silcprotocol.h
2882 lib/silccore/silcsockconn.h
2884 All core library headers are now formatted.
2886 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2888 * Fixed a bug in Irssi SILC client; do not show that you are
2889 server/router operator if you really are not. Affected file is
2890 irssi/src/silc/core/client_ops.c.
2892 * Renamed silc_command_free_payload to silc_command_payload_free.
2893 Affected file lib/silccore/silccommand.h
2895 * Added silcmath.h to include the prototoypes of various routines
2896 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2899 * Changed the following headers to ROBODoc format:
2901 lib/silccore/silcchannel.h
2902 lib/silccore/silccommand.h
2903 lib/silccore/silcid.h
2904 lib/silccore/silcidcache.h
2905 lib/silccore/silcmode.h
2906 lib/silccore/silcnotify.h
2907 lib/silccore/silcpacket.h
2908 lib/silcmath/silcmath.h
2910 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * Added checking to the server code not to start the server if
2913 ciphers and stuff are not configured properly. Affected files
2914 silcd/serverconfig.[h] and silcd/server.c.
2916 * Changed the layout of the header files of the public interfaces
2917 in the SILC libraries. The new layout supports ROBODoc
2918 documentation tool (and some others) so that it is easy to create
2919 a library reference manual. All the other headers and source
2920 code must still follow the CodingStyle document. Also source
2921 code must not include these ROBODoc stuffs, only the headers.
2922 Furthermore, all public interface headers must now be named
2923 by using `silc' prefix, example: silcapi.h, silccipher.h.
2924 Some files were renamed due to this. All the other headers
2925 must not be used as public interfaces. I will update the
2926 CodingStyle document later. Changed following headers, so far:
2928 lib/silcclient/silcapi.h
2929 lib/silccore/silcauth.h
2930 lib/silccore/silcprivate.h
2931 lib/silccrypt/silcdh.h
2933 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Removed silc_client_packet_send_flush from the client library
2938 as it is not needed. Affected file lib/silcclient/client.[ch].
2940 * Added printing of message of unresolved authentication method
2941 to the Irssi SILC client. Added it to the module formats.
2942 Removed the same message from the client library.
2944 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Added new distribution feature, DISTLABEL. Every distribution
2947 can define own preprocessor label that can be used in the
2948 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2949 file distributions, acconfig.h.pre and prepare.
2951 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Added Makefile.defines_int to include the actual definitions
2954 for Makefile.defines.in. Tested the new distribution system,
2955 created distributions and tested installation.
2957 * Added AWAY message printing to the Irssi SILC client. Added
2958 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2960 * Added SCONNECT command to call the SILC's CONNECT command.
2961 Cannot use CONNECT directly since Irssi uses that internally.
2962 Affected file irssi/src/silc/core/silc-servers.c.
2964 Added ACTION local command. It is same as ME command but takes
2965 the channel as mandatory argument.
2967 Rewrote some of the Irssi's help files to suite for SILC
2970 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2972 * Added Makefile.defines[.in] that should for now on be included
2973 in all Makefile.am file in the source tree. That file includes
2974 all common compilation definitions for SILC source tree.
2976 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Minor changes to the ./prepare script to change the package
2979 name according the distribution name to the configure.in.
2981 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * Created new distribution system. Added file `distributions'
2984 that defines all the distributions that can be created out of
2985 the SILC source tree. The ./prepare script now reads that
2986 file to determine how to prepare the distributions. The
2987 first argument to the ./prepare is the name of the distribution
2988 and second is the version of the distribution. If given
2989 without arguments it creates the default (toolkit) distribution
2990 with the default version (defined in ./prepare).
2992 All Makefile.am files that are subject to the distributions
2993 are now named as Makefile.am.pre. These are ./Makefile.am
2994 and lib/Makefile.am. Others may be changed later.
2996 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * Added invite list, ban list, some key management and connection
2999 error message printing to module formats in the Irssi SILC client.
3001 * Added new silc_client_set_away_message to set the away message
3002 that is back to the person who sent private message. The
3003 affected file lib/silcclient/silcapi.h and the
3004 lib/silcclient/client_prvmsg.c.
3006 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Fixed the private message sending in the Irssi SILC client,
3009 added local command KEY to the Irssi SILC client.
3011 Added key management and key agreement message formats to the
3012 irssi/src/fe-common/silc/module-formats.[ch].
3014 Added USERS (alias WHO) printing, server/router operator
3015 indication and LIST command printing to the module formats.
3017 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3019 * Fixed channel joining notify handling, cumode notify handling
3020 from Irssi SILC client.
3022 * Added SILC specific module-formats to the Irssi SILC client so
3023 that SILC specific message hilighting, colors etc is possible.
3024 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3026 Added channel mode, channel user mode, actions, notices,
3027 whois and whowas printing to the the module-formats.c.
3029 * Fixed a bug in channel deletion in the server. The channel
3030 is not left to the cache even if the channel founder auth mode
3031 is set when there are no users anymore on the channel. Affected
3032 file silcd/server.c.
3034 * The silc_net_localhost now resolves the entire hostname including
3035 the domain name. Affected file lib/silcutil/silcnet.c.
3037 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3039 * Changed the ask_passphrase client operation to be ascynchronous.
3040 It has now a completion callback and a context that the
3041 application must call after it has got the passphrase from
3042 the user. Affected files lib/silcclient/silcapi.h,
3043 lib/silcclient/protocol.c, lib/silcclient/command.c and
3046 Added SilcAskPassphrase callback that the application calls
3047 to deliver the passphrase to the library.
3049 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3050 The public key verification and especially a certificate
3051 verification is asynchronous procedure.
3053 Added new SILC_SKE_STATUS_PENDING status to indicate the
3054 request is pending and a callback will be called to finalize
3057 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3058 indicate that remote end did not send its public key (or
3059 certificate), even though we require it. Added check for this
3060 condition in the SKE. This was a security bug, now fixed.
3062 Defined new SilcSKEVerifyCbCompletion callback that is called
3063 when the verification process is completed.
3065 The affected files lib/silcske/silcske_status.h and
3066 lib/silcske/silcske.[ch].
3068 * Changed the verify_public_key client operation to be async
3069 as well. Defined SilcVerifyPublicKey callback that is used to
3070 indicate the success of the public key verification process.
3072 Changed the server and client to use the new async client
3075 * Changed the Irssi SILC client's internal scheduler to be called
3076 twice as many times as it used to be. As a result the client
3077 should be a bit faster now. Affected file is
3078 irssi/src/silc/core/silc-core.c.
3080 * Added support to Irssi SILC client of asynchronous public key
3081 verification and passphrase inquiry. Affected file is
3082 irssi/src/silc/core/silc-core.c.
3084 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Do not say "You have left channel %s" in client library.
3087 Moved it to the application. Affected files are
3088 lib/silcclient/command.c and silc/client_ops.c.
3090 * Fixed silc_client_get_clients. Command context was not
3091 duplicated and was freed memory in the callback. Affected
3092 file lib/silcclient/idlist.c.
3094 * Do not say "you are now talking..." on JOIN command in the
3095 client library. The appliation must handle it.
3097 * Do not say ".. changed topic to" in command reply in the
3098 client libary. The application must handle it.
3100 * Fixed TOPIC command sending in the client library.
3102 * Fixed a memory leak in silc_client_command_free in the file
3103 lib/silcclient/command.c.
3105 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Imported a modified version of Irssi client to the source tree.
3108 The Irssi will be used to create a new client called
3109 Irssi SILC. Imported to irssi/.
3111 Added silc_core_init_finish function to the Irssi. Affected
3112 file irssi/configure.in.
3114 A lot changes in the Makefile.ams around the irssi tree.
3116 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Do not rehash if the new size is same as the old size of the
3119 hash table, in the silc_hash_table_rehash*. The affected file
3120 lib/silcutil/silchashtable.c.
3122 * Replaced hash_table_del_by_context calls from the server
3123 (when channel->user_list and client->channels) to the
3124 hash_table_del as it is sufficient and faster.
3126 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Added silc_hash_table_list, silc_hash_table_get and the
3129 SilcHashTableList structure to provide an alternative way to
3130 traverse the hash table. The affected files are
3131 lib/silcutil/silchashtable.[ch].
3133 * Changed the server's idlist routines to use the hash table
3134 routines to optimize the code.
3136 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Replaced the client entry's `channel' list and channel entry's
3139 `user_list' list to hash tables for optimized lookup. Changed
3140 the code to use the hash table interface around the code.
3141 Affected file lib/silcd/idlist.[ch].
3143 * Added `auto_rehash' boolean argument to the function
3144 silc_hash_table_alloc to indicate whether the hash table should
3145 auto-rehash when it thinks is appropriate time. It will
3146 increase the hash table size if the there is twice as much
3147 entries in the table than the size of the table, and will
3148 decrease the size if there are twice as less entries than
3149 the size of the table.
3151 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3155 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * silc_idcache_purge_by_context deletes the entry now by context
3158 as it is supposed to do. Affected file lib/silccore/idcache.c.
3160 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3161 client is not anymore valid (WHOWAS givens the info) and not
3162 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3164 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Removed the `data' and `data_len' arguments from the ID Cache
3167 interfaces and added `name' argument. ID Cache does not handle
3168 anymore the binary data only a names associated with given ID.
3170 * When hashing a Client ID with silc_hash_id the entire ID is
3171 not hashed anymore, instead only the hash of the Client ID is
3172 hashed. This way we can access the Client ID from the cache
3173 with Client ID but with the hash of the ID (which is a hash of
3174 the nickname) as well without any difference in performance.
3176 Added also silc_idcache_find_by_id_one_ext to do one on one
3177 searching when we have the actual ID. Added also function
3178 silc_hash_client_id_compare. The affected files are
3179 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3181 * When hashing the name associated with a ID it is always done
3182 in lowercase. This way we can access the cache without worrying
3183 about case-sensitivity, even though, for example nicknames are
3186 * Fixed a bug in server with channel message sending. It put
3187 wrong ID type as destination ID. The affected file
3188 silcd/packet_send.c.
3190 * silc_idcache_del_by_context now deletes from all hash tables
3191 by context. Affected file lib/silccore/idcache.c.
3193 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Changed the client library to use the new ID Cache interface.
3196 Changes around the source tree.
3198 * Added silc_hash_table_rehash_ext to rehash with specific
3199 hash function. Affected file lib/silcutil/silchashtable.[ch].
3201 * Added silc_hash_string_compare to compare two strings in the
3202 hash table. Affected file lib/silcutil/silcutil.[ch].
3204 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Added new function silc_idcache_del_by_context into the
3207 lib/silccore/idcache.[ch].
3209 * Changed the server's ID list routines to use the new ID Cache
3210 interface. Changes around the source tree.
3212 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Added silc_hash_table_del[_by_context]_ext functions in to the
3215 lib/silcutil/silchashtable.[ch].
3217 Removed silc_hash_table_find_all* routines and added new
3218 silc_hash_table_find_foreach to replace them.
3220 Added silc_hash_table_replace_ext function as extended
3221 replacing function. Separated the simple hash table interface
3222 from the extended hash table interface in the file
3223 lib/silcutil/silchashtable.h.
3225 * Fixed minor bugs and changed it to use some of the new
3226 hash table functions in lib/silccore/idcache.c
3228 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3230 * Added new function silc_hash_table_find_all to return all keys
3231 in the hash table by the specified key. As the hash table is
3232 collision resistant it also makes it possible to have several
3233 duplicate keys in the hash table. This function may be used to
3234 find all of the keys from the hash.
3236 Added user_context arguments to the SilcHashFunction,
3237 SilcHashCompare and SilcHashDestructor to deliver user specified
3240 Added new fuctions silc_hash_table_find[_all]_ext to do
3241 extended lookup with specified hash and compare functions and
3242 specified user contexts.
3244 Added new function silc_hash_table_add_ext to add the key
3245 with specified hash function and user context.
3247 Added new function silc_hash_table_foreach to traverse all
3248 entrys in the hash table. Added SilcHashForeach callback
3251 Added new function silc_hash_table_del_by_context to delete
3252 the entry only if the context associated with the key matches.
3254 Affected files are lib/silcutil/silchashtable.[ch].
3256 * Removed silc_hash_[server/client/channel]_id and added just
3257 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3258 silc_hash_id_compare to compare two ID's using as the hash table
3259 comparison function. Added also silc_hash_data to hash
3260 binary data and silc_hash_data_compare to compare it.
3262 * Removed silc_idlist_find_client_by_hash as it is not needed
3263 anymore. Affected file silcd/idlist.[ch].
3265 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3266 to use internally the SilcHashTable. The new ID Cache is a lot
3267 faster than the old one. Some of the ID Cache interface was also
3268 rewritten and obsolete and stupid functions were removed.
3270 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Added entry_count field to the SilcHashTable to keep the number
3273 of the entries in the table. Implemented the function
3274 silc_hash_table_rehash. Added new function
3275 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3277 Fixed a minor bug in silc_hash_table_free.
3279 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3280 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3281 into the lib/silcutil/silcutil.[ch].
3283 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Implemented a collision resistant hash table into the
3286 lib/silcutil/silchashtable[ch]. See the header and the source
3287 for the SilcHashTable API.
3289 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Merged dotconf version 1.0.2 into lib/dotconf.
3293 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * Do not compile anything in lib/silcsim/* if the SIM support
3296 is not enabled. The tree should now compile without problems
3299 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * Compiled the SILC under cygwin. Compiled and tested briefly
3302 without problems. More tests needed. The SIMs didn't compile
3305 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3307 * Fixed possible crash in silc_get_username in the
3308 lib/silcutil/silcutil.c.
3310 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Fixed a va_arg in silc/client_ops.c.
3314 * Oops, RC5 routines were named AES and caused some problems
3315 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3317 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Added new SilcIDIP structure into the lib/silccore/id.h and
3320 replaced the old `ip' fields from all SILC ID's to that type.
3321 This is a step towards IPv6 support.
3323 The silc_id_get_len takes now the ID as an extra argument.
3324 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3325 both IPv4 and IPv6 based ID's.
3327 The affected files are lib/silccore/id.[ch] and other files
3328 around the tree using these routines.
3330 * Removed the ID length arguments in server from various
3331 silc_server_send_notify_* routines -> they are not needed
3334 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Fixed memory leak in silc_encode_pem_file in the file
3337 lib/silcutil/silcutil.c.
3339 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Check minor version as well in the SKE. Affected files are
3342 silcd/protocol.c and lib/silcclient/protocol.c.
3344 * Added --identifier option to the server so that an identifier
3345 can be when creating the public key for the server. Affected
3346 file is silcd/silcd.c.
3348 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3349 lib/silccrypt/silcpkcs.c.
3351 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * Register default ciphers and stuff when using -C option with
3354 the server. Affected file sildc/silcd.c.
3356 * Put back the servers public key filename format, it is better
3357 than the new one. For now, the client keys are saved with the
3358 new filename format. The affected file silc/client_ops.c.
3360 * Implemented the Cipher API for the rest of the ciphers that
3361 did not implement it or implemented it the wrong way.
3363 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * Register default ciphers and stuff when using the -S option
3366 in the client. Affected file silc/silc.c. Same also when
3367 creating new key pair with -C option.
3369 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * Fixed the silc_verify_public_key client operation function to
3372 save the public keys differently. The fingerprint is now
3373 used as filename and not the hostname. This way also the
3374 client keys are saved uniquely and not with hostnames. The
3375 affected file is silc/client_ops.c.
3377 * Trimmed the silc_hash_fingerprint function to remove extra
3378 whitespaces from the end of the fingerprint. The affected
3379 file is lib/silccrypt/silchash.c.
3383 * Added silc_cipher_register_default function to register all
3384 default ciphers. It can be used when configuration files
3385 does not exist and the application does not want any specific
3386 ciphers in any specific order.
3388 The SilcDList is now used as silc_cipher_list dynamically
3389 allocated cipher list. Removed the static list all together
3390 and now all ciphers must be allocated to the dynamic list.
3391 The silc_cipher_alloc routine was changed to check only the
3394 All silc_cipher_* routines that used to return int returns
3397 The affected files lib/silccrypt/silccrypt.[ch].
3399 * The same thing was done to silc_hash_* as for silc_cipher_*
3400 routines. Affected files lib/silccrypt/silchash.[ch].
3402 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3403 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3404 Added also silc_pkcs_[un]register[_default] functions.
3405 Removed the data_context from the PKCS API.
3407 * Added silc_hmac_register_default function to register default
3408 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3409 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3410 to unregister all hmacs at once.
3412 * Register the default ciphers, hash functions, PKCSs and HMACs
3413 if client's configuration file does not exist. The affected
3416 * The client did not load the hash functions from the SIM
3417 modules at all. Added support for this. Affected file is
3418 silc/clientconfig.c.
3420 * When decoding public key with silc_pkcs_public_key_decode, check
3421 the supported algorithm only if PKCS are registered. Affected
3422 file lib/silccrypt/silcpkcs.c. The same was done with the
3423 silc_pkcs_private_key_decode.
3425 * Fixed the SILC List routines to keep the list always in order.
3426 It used to change the list's order when traversing the list but
3427 not it preserves the order. Affected file lib/trq/silclist.h.
3429 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Added the client library to use the SilcSocketConnection's
3432 reference counter (by silc_socket_dup) to prevent the bug that
3433 the socket object may be freed underneath async operation.
3435 * The name resolv library checking fixes in the configure.in.pre.
3438 * Created new version of the protocol drafts for future
3439 development. The -03 drafts are the ones that will be changed
3440 in the trunk now and the -02 will remain as they are.
3442 * Send list of CUMODE notifys to the router when announcing
3443 the channel users to the router. Affected file silcd/server.c.
3444 If the router receiving channel founder CUMODE for a channel
3445 that already has channel founder it will send CUMODE notify
3446 to the sender to remove the channel founder rights from the
3447 announced client. Affected file silcd/packet_receive.c.
3449 * The CUMODE notify may now use Server ID as well as the entity
3450 who changes the mode. Updated protocool specs.
3452 * Updated INSTALL and README files.
3454 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3456 * New web pages in the http://silc.pspt.fi. The pages was
3461 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Implemented the [DenyConnectin] config section in the server.
3464 Added silc_server_config_denied_conn to check whether incoming
3465 connection is denied. Affected file silcd/serverconfig.[ch].
3467 * Do not check the ports when checking the incoming configuration
3468 data if the port is 0, meaning any. Affected file is
3469 silcd/serverconfig.c.
3471 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3473 * Fixed buffer overflow in silc_string_compare in the file
3474 lib/silcutil/silcutil.c.
3476 * Fixed double free in silc_server_command_leave in the file
3479 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Fixed the version checking in the server. Affected file is
3484 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Fixed the configuration data fetching when accepting new
3487 connections in the server. Affected file silcd/server.c.
3489 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Added `sender_entry' argument to the function
3492 silc_server_packet_relay_to_channel so that we can check
3493 whether some destination actually belongs to the same route
3494 the sender belongs (ie, we must not resend the packet to the
3495 sender). Affected file silcd/packet_send.[ch].
3497 * Added `servername' field to the SilcClientEntry in the server
3498 to hold the name of the server where client is from. Affected
3499 file is silcd/idlist.h.
3501 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Moved the channel message encrypting in the router betwen
3504 router connections from silc_server_channel_message to the
3505 silc_server_packet_relay_to_channel since we want to check
3506 whether we have anybody channel before encrypting anything.
3507 Affected files silcd/packet_[receive/send].c.
3509 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Fixed the [AdminConnection] server config section to support
3512 multiple entries. Affected file silcd/serverconfig.c.
3514 * Added support into the server to check the validity of the
3515 incoming connection before executing any KE or authentication
3518 * The connection configuration is now saved to the KE and
3519 connection auth protocol contexts and not fetched anymore in
3520 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3522 * The local hosts listenning address and port is also resolved
3523 now when starting the server. We want to have the socket object
3524 to include the real address and port for the listener. Added
3525 new function silc_net_check_local_by_sock into the files
3526 lib/silcutil/silcnet.[ch].
3528 * Fixed a broadcast bug in server -> do not broadcast if we
3531 * Fixed a routing bug. Do not route broadcast packets ever.
3532 Broadcast packets must be processed always and not routed since
3533 they may be destined to some other host than yourself and thus
3534 would get routed without no good reason. Affected file is
3537 * Added function silc_server_config_is_primary_route to check
3538 whether primary router connection has been configured (a router
3539 configuration that we are initiating). If there is not, we
3540 will assume that there is only two routers in the SILC network
3541 and we will use the incoming router connection as our primary
3542 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3544 * Changed the order of the broadcasting. Broadcast _after_ the
3545 packet has been processed not before. Affected file is
3548 * Fixed a [ClientConnection] parsing bug. The port was never
3549 parsed correctly thus resulting to port 0. Affected file
3550 silcd/serverconfig.c.
3552 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3553 argument and did not set the broadcast packet flag. Affected
3554 file silcd/packet_send.c. Fixed same bug in the function
3555 silc_server_send_notify as well.
3557 * If we receive NEW_ID packet for our own ID in the server, ignore
3560 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Removed the nickname from the Private Message Payload.
3565 Updated the code and the protocol specs.
3567 * Updated protocol specs for submitting to the IETF.
3569 * Tweaked the Random Number Generator a bit. Affected file
3570 lib/silccrypt/silcrng.c. Exported a new function
3571 silc_rng_[global]_add_noise which can be used to add more
3574 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Do not parse packets with different timeout when protocol
3577 is active -> may cause problem with rekey. Affected file
3580 * When server receives signoff notify it must not create
3581 new channel key if the client is on any channels since the
3582 sender of the signoff notify will create it.
3584 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3586 * Added printing of error messages during SKE protocol from the
3587 failure packet sent by server during SKE. Affected file
3590 * Removed the client's failure_callback handling with timeout
3591 and handle it immediately when received.
3593 * The SKE library returned wrong type in SUCCESS and FAILURE
3594 packets. They must be 32 bit MSB not 16 bit MSB.
3596 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Ok, rewrote the logic of the re-key and now it seems to work.
3599 I tested it on high traffic with frequent re-keys without
3600 problems. Added hmac_receive (and renamed hmac to hmac_send)
3601 in SilcClientConnection in lib/silcclient/client.h and
3602 in SilcIDListData in silcd/idlist.h. Also, removed the
3603 SilcPacketParserContext's cipher and hmac fields as they are
3604 not needed anymore and actually caused some problems when
3605 the ciphers and hmac's changed underneath the packet parser.
3607 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3609 * If re-key protocol is active then process the incoming packets
3610 synchronously since we must assure that icoming packets encrypted
3611 with the old key is processed before the new keys is set to
3612 use. This is true other packets than for REKEY packets.
3613 Affected file silcd/server.c. The same was done to client library
3614 as well, affected file lib/silcclient/client.c.
3616 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3618 * Fixed bug in client and server to accept the force send if
3619 the packet is send from silc_[server/client]_packet_process
3620 function. Otherwise the packets are never delivered, oops.
3622 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Disable force sending of packets when REKEY protocol is active.
3625 We must assure that no packet is sent directly when rekey is
3626 performed. All packets must be sent through packet queue.
3627 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3628 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3629 function is silc_[server/client]_packet_send_real to check
3632 * Replaced the SIM paths from example config files to
3633 /usr/local/modules. Also, make install creates now
3634 /usr/local/silc/logs directory to hold all the SILC server
3637 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Made the configure.in.pre work on Solaris. Patch by salo.
3641 * Made all ciphers compatible with non-x86 machines. Defined
3642 CBC mode macros into lib/silccrypt/ciphers_def.h.
3644 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Fixed the make install.
3648 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * When MAC computation fails the silc_packet_decrypt returned 0
3651 even though it was supposed to return -1. Fixed this. The
3652 affected file is lib/silccore/silcpacket.c.
3654 * Do not replace the config files in /etc/silc (in make install)
3655 if they already exist. Affected file ./Makefile.am.
3657 * Do not send re-key packets immediately but through packet queue.
3658 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3660 * Changed silc_net_check_host_by_sock to return FALSE if the
3661 IP/DNS could not be resolved. Though, it returns the IP address
3662 now even if it could not resolve it (but returns also FALSE).
3663 Affected file lib/silcutil/silcnet.[ch].
3665 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Added silc_pkcs_decode_identifier to decode the public key's
3668 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3669 Added also silc_pkcs_free_identifier. Added also new context
3670 SilcPublicKeyIdentifier.
3672 * Added -S option to the silc client. It is used to dump the
3673 contents of the specified public key file.
3675 * Changed the PKCS api to return the public key length when
3676 setting the public key.
3678 * Fixed a fatal bug in the public and private key file loading.
3679 Affected file lib/silccrypt/silcpkcs.c.
3681 * Execute the packet parsing for client with zero (0) timeout
3682 if the protocol is active. Affected file silcd/server.c.
3684 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Made the key generation options to the silcd program. Added
3687 -C option, equivalent to client's option.
3689 * Added new [ServerKeys] config section to the server. It
3690 configures the server's public and private key.
3692 * Defined generic Public Key Payload into the protocol
3693 specification to send specific type of public keys and
3696 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3697 public key or certificate.
3699 * Implemented the GETKEY command to the server and to the
3700 client library and on user interface.
3702 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3704 * Made preliminary `make install' work.
3706 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Added SilcServerRekey context into silcd/idlist.h.
3710 * Added the PFS support as defined in the specification to the
3711 SKE protocol. Affected files lib/silcske/*.c.
3713 * Added `ske_group' field to the SilcServerRekey context to hold
3714 the number of the SKE group that is used with PFS in re-key.
3715 Affected file silcd/idlist.h.
3717 * Added PFS re-key support to the server. Affected file is
3720 * Added silc_protocol_cancel to cancel execution of the next
3721 state of the protocol. Affected file is
3722 lib/silccore/silcprotocol.[ch].
3724 * Added the re-key support with and without PFS to the client
3725 library. Re-key is performed once in an hour, by default.
3727 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3728 Added silc_client_rekey_callback and silc_client_rekey_final.
3729 Affected files are lib/silcclient/protocol.[ch] and
3730 lib/silcclient/client.[ch].
3732 * Removed the `hmac_key' and `hmac_key_len' fields from the
3733 SilcClientConnection structure; not needed. Affected file is
3734 lib/silcclient/client.h.
3738 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Do not ask whether user wants to use the negotiated private key
3741 for private messages, just use it. Affected file is
3742 silc/local_command.c.
3744 * Added `send_enc_key' and `enc_key_len' fields to the
3745 SilcIDListData structure since they are needed in the re-key
3746 phase. Affected file is silcd/idlist.[ch].
3748 * Implemented the simple re-key protocol into the server.
3749 Affected files silcd/server.c and silcd/protocol.[ch]. The
3750 re-key will be performed once in an hour, by default.
3752 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3753 Added silc_server_rekey, silc_server_rekey_callback and
3754 silc_server_rekey_final.
3756 * Removed Tunneled flag from the protocol. Updated the code
3757 and the specifications.
3759 * Adde `pfs' field to the SilcIDListData to indicate whether
3760 the PFS is to be performed in the re-key. Affected file is
3763 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3766 int64 of at least the xintXX size. If void * is less that 4
3767 bytes uint32 * will be used. Defined bool as boolean.
3769 * Changed _ALL_ unsigned long and unsigned int to uint32,
3770 unsgined short to uint16 in the source tree.
3772 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3773 not handle clients that has entry->data.registered == FALSE.
3774 They are not in the network anymore. Affected file is
3777 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Implemented the sending of the SERVER_SIGNOFF notify in the
3780 server. Affected file is silcd/server.c.
3782 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3783 Added also silc_notify_payload_encode_args into the
3784 lib/silccore/silcnotify.[ch].
3786 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3787 Affected file silcd/packet_receive.c.
3789 * Implemented the SERVER_SIGNOFF notify handling in the client
3790 library. Affected file lib/silcclient/client_notify.c. Also,
3791 implemnted the printing of the SERVER_SIGNOFF info to the
3792 application. Affected file silc/client_ops.c.
3794 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3795 if the deleting was successful. Affected file silcd/idlist.[ch].
3797 * Added support for public key authentication in the connection
3798 authentication protocol in the client library. Affected file
3799 lib/silcclient/protocol.c.
3801 * Changed the server's silc_idlist_get_clients_by_* interface
3802 to support already allocated array so that new entries may be
3803 added to pre-allocated array. Affected file silcd/idlist.[ch].
3804 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3805 and command replies.
3807 * All command reply functions in the server now calls the
3808 pending command callback even if error occured. This way the
3809 error will be delivered to the client as well. Affected files
3810 silcd/command.c and silcd/command_reply.c.
3812 * Fixed INFO command to return local server's info if no server
3813 was provided. Affected file lib/silcclient/command.c.
3815 * Removed RESTART command for good. Updated the code and the
3818 * Rewrote parts of the task system. It is a bit simpler now.
3819 Removed unsued task priorities. The affected files are
3820 lib/silcutil/silctask.[ch].
3822 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Moved the USERS printing from the library to the application.
3825 Affected files lib/silcclient/command.c and silc/client_ops.c.
3827 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Added channel key re-key support. The re-key is perfomed
3832 only by the router and is done once in an hour. Added `rekey'
3833 field to the SilcChannelEntry in the server. Affected files
3834 silcd/server.c and silcd/idlist.h.
3836 * Added silc_task_unregister_by_context into the file
3837 lib/silcutil/silctask.[ch].
3839 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Added SILC_UMODE_GONE mode to indicate when the client is not
3842 present in the SILC network. Added also support to the local
3843 command AWAY that will set this mode. Added support of showing
3844 "xxx is gone" in WHOIS command. The USERS command shows the
3845 gone status as well.
3847 * Fixed setting server and router operator privileges in the
3848 server's UMODE command. Affected file silcd/command.c.
3850 * Merged the SKE KE1 and KE2 payloads into one payload. The
3851 new KE payload is equivalent to the old KE2 payload.
3853 Cleaned up the SKE Start Payload parsing. It now uses the
3854 simple buffer unformatting to do the parsing. A lot faster
3857 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3858 to the SKE that is used to indicate whether both of the SKE
3859 parties should perform authentication. By default only the
3860 responder performs authentication. By setting this flag also
3861 the initiator must do authentication. By default it is unset
3862 since in normal SKE case, client to server connection, only
3863 the responder should do authentication. When doing SKE between
3864 two clients both should perform authentication. Updated the
3865 code and the protocol specs.
3867 * A little fix to IDENTIFY command in the server. Search the
3868 client first by hash not nickname. Affected file is
3871 * Fixed the silc_client_close_connection to support closing
3872 the client to client connections wihtout deleting too much
3873 data. Affected file lib/silcclient/client.c.
3875 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3876 are received if protocol used to be active but is not anymore
3877 the application would crash due to NULL pointer dereference.
3878 Affected files silcd/server.c and lib/silcclient/client.c.
3880 * Added `hash' field to the SilcClientConnection to include
3881 the hash function negotiated in the SKE protocol.
3883 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3884 to set the channel founder authentication data. A client can
3885 claim the founder rights later by providing the authentication
3886 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3887 This way the channel founder can regain the channel founder
3888 privileges even it is left the channel. This works only on
3889 local server and the client must be connected to the same
3890 server to be able to regain the founder rights. Updated the
3891 protocol specs accordingly.
3893 Added support to the CMODE command in the client to set the
3894 founder auth data. Read the README to see how to set it.
3896 Added support to the CUMODE command to claim the founder
3897 rights. Read the README to see how to do it.
3899 Added support for the founder authentication to the Channel
3900 Entry in the server. Affected file silcd/idlist.h.
3902 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3903 server's CMODE command. Affected file silcd/command.c.
3905 * Added the following new functions into lib/silccore/silcauth.[ch]:
3906 silc_auth_get_method and silc_auth_get_data.
3908 * The server now saves the remote hosts public key to the
3909 SilcIDListData pointer. Affected file silcd/protocol.c.
3911 * The normal server now does not remove the channel entry from
3912 the cache if the founder authentication data is set. It used
3913 to remove it if the founder was the last one on the channel on
3914 the server and left the channel. The auth data is saved and
3915 if the channel is re-joined later the old entry is used with
3916 the old auth data. Affected files silcd/command_reply.c and
3919 * Removed the `pkcs' field from the SilcIDListData structure
3920 in the server; it is not used. Affected file silcd/idlist.h.
3922 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Fixed packet processing on slow links. Partial packets were
3925 never re-processed because the incoming data buffer was cleared
3926 by the application. Application must not directly clear the
3927 sock->inbuf, the packet processing routines handle it. Fixed
3928 this in client library and in server.
3930 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Fixed the WHOIS and IDENTIFY send reply function to really
3933 check whether to send list or just one entry. Affected file
3936 * Cleaned up the LEAVE command's channel key distribution. The
3937 affected file silcd/command.c.
3939 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3940 can enforce the channel mode as well. In that case the ID
3941 includes the ID of the server. The code now enforces the
3942 mode change if the router have different mode than the server.
3944 * The notify client operation with CMODE_CHANGE notify can now
3945 return NULL client_entry pointer if the CMODE was not changed
3946 by client. Application must check for this.
3948 * Added <Server ID> argument to INFO command to support server
3949 info fetching by Server ID.
3951 * Added silc_server_announce_get_channel_users to get assembled
3952 packets of channel users of the specified channel. Affected
3953 file silcd/server.[ch].
3955 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3956 was freed underneath the ID Cache.
3958 * Re-announce clients when the server received CHANNEL_CHANGE
3959 notify from the router. Affected file silcd/packet_send.c.
3961 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3964 crashed since it did not handle the fact that there is no cipher
3965 called "3" and didn't check the error condition. Now fixed.
3967 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3968 flag. It can be used to send message requests.
3970 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3972 * Implemented the RESTART command in the client.
3974 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3975 notice type messages. Added notice printing to the user
3978 * The channel keys are not re-generated if the channel's mode
3979 is PRIVKEY, ie private key on the channel exists. Affected
3980 files silcd/server.c and silcd/command.c.
3982 * Fixed a little bug in channel message delivery when channel
3983 private keys are set in the server. Affected file is
3984 silcd/packet_send.c.
3986 * Changed the setting on channel->on_channel = TRUE from the
3987 silc_client_save_channel_key to the JOIN command reply. The
3988 key payload is not received if the private channel key is set.
3989 Affected file lib/silcclient/command_reply.c and the
3990 lib/silcclient/client_channel.c.
3992 * When the CMODE_CHANGE notify is sent and the channel private
3993 key mode is removed the channel key must be re-generated in
3994 other cells as well. Added this support for the router in the
3995 silcd/packet_receive.c.
3997 * Added new local command NOTICE to send notice message on
3998 channel. Affected file silc/local_command.[ch].
4000 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Added new local command ME to the client. It is used to send
4003 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4004 some action. Affected file silc/local_command.[ch].
4006 * Changed channel_message and private_message client operations
4007 to deliver the message flags to the application. Added also
4008 the `flags' arguments to the silc_client_send_channel_message
4009 and silc_client_send_private_message functions. Affected file
4012 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Redefined the Private Message Payload to support private message
4015 keys and to support the new private message flags. Updated
4016 the protocol specs. Flags makes it possible to have for example
4017 CTCP style messages.
4019 * Added new type SilcPrivateMessagePayload and defined an API
4020 for it in the lib/silcclient/silcprivate.[ch].
4022 * Tested private message private keys successfully. Tested the
4023 private message key set, unset and list commands with the new
4026 * Redefined the Channel Message Payload to include the channel
4027 message flags (equal with private message flags) to support
4028 for example CTCP style messages.
4030 * Defined some of the message (for channel and private message)
4031 flags. Updated the protocol specs and added the flags to the
4032 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4034 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Added SilcKeyAgreementStatus type to the key agreement routines
4037 to indicate the current status and error if one occured.
4038 The status types are defined in the lib/silcclient/silcapi.h.
4040 * Added new local command KEY that is used to set and unset private
4041 keys for channels, set and unset private keys for private messages
4042 with remote clients and to send key agreement requests and
4043 negotiate the key agreement protocol with remote client. The
4044 key agreement is supported only to negotiate private message keys,
4045 it currently cannot be used to negotiate private keys for channels,
4046 as it is not convenient for that purpose.
4048 * Fixed a minor pending callback setting bug in the function
4049 silc_client_get_client_by_id_resolve, now the function works.
4050 Affected file lib/silcclient/idlist.c.
4052 * Added function silc_net_get_local_port to get local bound
4053 port by socket. Added to lib/silcutil/silcnet.[ch].
4055 * Added `sockets' and `sockets_count' fields to the SilcClient
4056 object. They hold the sockets of the listenning sockets in
4057 the client. Listenning sockets may be for example the key
4058 agreement server. Affected file lib/silcclient/client.[ch].
4059 Added functions the silc_client_add_socket and the
4060 silc_client_del_socket. They are exported to the application
4063 * Added ~./silc/clientkeys to support other client's public keys.
4065 * Renamed verify_server_key client operation to verify_public_key
4066 and added one argument to indicate the type of the connection
4067 (server, client etc.).
4069 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Added silc_server_connection_auth_request to handle the
4072 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4073 silcd/packet_receive.[ch].
4075 * Added silc_server_send_connection_auth_request into the
4076 silcd/packet_send.c to send the connection auth request packet.
4078 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4081 * Fixed the public key authentication in responder side in the
4082 server. The `auth_data' pointer includes the SilcPublicKey
4083 not the path to the public key. Affected file silcd/protocol.c.
4085 * Implemented the public key authentication in the initiator side
4086 in the server. Affected file silcd/protocol.c.
4088 * Removed the [RedirectClient] config section from the server
4089 configuration. Is not needed and I don't want to implement it.
4091 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * Cleaned up the CMODE command in the server. It now works
4094 correctly and supports all the modes defined in the protocol.
4095 Affected file is silcd/command.c.
4097 * Added `hmac_name' field to the SilcChannelEntry in the server
4098 to hold the default HMAC of the channel. It can be set when
4099 creating the channel (with JOIN command). Affected files
4102 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4103 type to indicate the change of the current cipher and hmac
4104 on the channel. Client can safely ignore the <cipher> argument
4105 (if it chooses to do so) since the CHANNEL_KEY packet will
4106 force the channel key change anyway. The <hmac> argument is
4107 important since the client is responsible of setting the new
4108 HMAC and the hmac key into use.
4110 * Fixed the CMODE command in the client library as well.
4112 * Tested CMODE command in router environment successfully.
4114 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Show the version of the remote client (or server) when connecting
4117 to the server. It is logged to the log file. Affected file
4118 is silcd/protocol.c.
4120 * Fixed the KILLED notify handling in the client library. The
4121 client must be removed from all channels when receiving the
4124 Also, do not remove the client entry when giving the KILL
4125 command but when the KILLED notify is received.
4127 * Removed silc_idlist_find_client_by_nickname from the server.
4128 Not needed anymore. Affected files silcd/idlist.[ch].
4130 * Implemented the CHANNEL_CHANGE notify type handling to the
4131 server. Affected file silcd/server.c.
4135 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Added silc_server_send_notify_invite to send the INVITE
4138 notify between routers.
4140 * Implemented the INVITE command correctly to the server.
4142 * Implemented the INVITE notify type handling in the server.
4144 * Implemented the INVITE command to the client library and on the
4147 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Added function silc_server_get_client_resolve to find the
4150 client entry by ID from all ID lists and then resolve it
4151 (using WHOIS) if it cannot be found. Affected file is
4154 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Implemented the BAN command to the client library.
4158 * The JOIN command in the server now checks the invite list
4161 * Changed the silc_command_reply_payload_encode_va and the
4162 silc_command_payload_encode_va to support that if argument is
4163 NULL it ignores and checks the next argument. Affected file
4164 lib/silccore/silccommand.c.
4166 * Added silc_server_send_notify_ban to send the BAN notify
4167 type between routers.
4169 * Chaned the silc_notify_payload_encode to support that if
4170 argument is NULL it ignores and checks the next argument.
4171 Affected file lib/silccore/silcnotify.c.
4173 * Tested ban lists in router environment successfully.
4175 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Implemented BAN command to the server, in silcd/command.[ch].
4179 * Removed the BAN and INVITE_LIST modes from the CMODE command
4182 * Added function silc_string_match to regex match two strings.
4183 Affected files lib/silcutil/silcutil.[ch].
4185 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Redefined parts of the SilcChannelEntry in the server to support
4188 the new ban and invite lists.
4190 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Redefined the INVITE command. The same command can be used to
4193 invite individuals to the channel but also to manage the invite
4194 list of the channel (to add to and remove from the invite list).
4195 Updated the protocol specs.
4197 * Added new command SILC_COMMAND_BAN that can be used to manage
4198 the ban list of the channel. Updated the protocol specs.
4200 * Removed the channel modes: the SILC_CMODE_BAN and the
4201 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4202 in the CMODE command. The equivalent features are now available
4203 using INVITE and BAN commands. Updated the protocol specs.
4205 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4206 in the network about change in the current ban list. The notify
4207 type is not used by the client.
4209 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4210 support the invite lists.
4212 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Added new function silc_string_regexify that converts string
4215 including wildcard characters into regex string that can
4216 be used by the GNU regex library. Added into the file
4217 lib/silcutil/silcutil.[ch].
4219 Added silc_string_regex_combine to combine to regex strings
4220 into one so that they can be used as one regex string by
4221 the GNU regex library. Added into the file
4222 lib/silcutil/silcutil.[ch].
4224 Added silc_string_regex_match to match two strings. It returns
4225 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4227 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Imported GNU regex to the soruce tree into lib/contrib.
4230 Fixed some compiler warning from the regex.c.
4232 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Fixed MOTD command in the server to work in router environment.
4236 * Fixed the MOTD command in the client library to support
4237 the server argument in the command.
4239 * Added `nickname_len' argument to the silc_idlist_add_client
4240 in the server, as the `nickname' argument may be binary data
4243 * Added silc_idlist_get_channels to return all channels from
4246 * Implemented LIST command to the server. Affected file is
4249 * Implemented the LIST command to the client library and on the
4252 * Added [<user count>] argument to the LIST command reply.
4253 With private channels the user count is not shown.
4255 * Updated TODO and README.
4257 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * The client entry's data.registered must be TRUE even with
4260 global client entry on global client list. The data.registered
4261 is used to check whether the client is anymore in the network,
4262 for example with WHOWAS command so it must be valid.
4264 * Fixed the WHOWAS command in the server. It now actually works
4265 in router environment. Added function into silcd/command_reply.c
4266 silc_server_command_reply_whowas_save.
4268 * Added silc_idlist_purge function to the silcd/idlist.c
4269 to periodically purge the ID Cache.
4271 * Fixed INFO command in the server. It works now in router
4272 environment. Added <server name> argument to the INFO command
4273 reply. Updated the protocol specs.
4275 * Fixed minor bug in silc_idcache_purge to not purge if the
4276 expire value is zero.
4278 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4279 they were buggy because of the WHOWAS information.
4281 * Fixed local command MSG to handle the async resolving of
4282 the remote client properly. It used to fail the first MSG.
4283 Affected file silc/local_command.c.
4285 * Added `data_len' field to SilcIDCache context.
4287 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Update TODO. Todo in commands in the server.
4291 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4293 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4294 used by routers as broadcast packet to inform other routers
4295 about the changed user mode.
4297 Implemented the notify handling in the server. Affected file is
4298 silcd/packet_receive.c. Added the function
4299 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4301 * Added new generic Channel Payload and deprecated the New Channel
4302 Payload. The New Channel Payload is now the generic Channel
4305 * Added new argument `mode' to the silc_server_send_new_channel
4306 as it is required in the Channel Payload now.
4308 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4309 and created a new and real SilChannelPayload to represent the
4310 new generic Channel Payload. Implemented the encode/decode
4311 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4313 * Added silc_server_get_client_channel_list to return the list
4314 of channels the client has joined for WHOIS command reply.
4315 Affected file silcd/server.[ch].
4317 * Implemented the channel list sending in the WHOIS command reply
4318 in server and in the client.
4320 Implemented the channel list displaying on the user interface
4321 as well. Affected file silc/client_ops.c.
4323 * Added silc_channel_payload_parse_list to parse list of Channel
4324 Payloads. It returns SilcDList list of SilcChannelPayloads.
4325 Client for example can use this function to parse the list of
4326 channels it receives in the WHOIS command reply. The caller
4327 must free the list by calling silc_channel_payload_list_free.
4328 Affected files lib/silccore/silcchannel.[ch].
4330 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Added one new argument <user mode> to the WHOIS command reply
4333 to return the mode of the user in SILC. Updated the protocol
4336 Implemented it to the server and client.
4338 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Fixed the mode printing on the user interface on joining.
4341 Affected file silc/client_ops.c.
4343 * Implemented the UMODE command and user modes in general to the
4344 client library and to the user interface.
4346 * Implemented the UMODE command to the server.
4348 * The server now sends UNKNOWN_COMMAND error status if client sends
4349 unknown command. Affected file silcd/command.c.
4351 * All server commands now handle the command identifier the right
4352 way when sending the command reply to the client. The client can
4353 use to identify the command replies with the identifier.
4355 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Added silc_server_get_client_route to resolve the route to
4358 the client indicated by the client ID. Affected file is
4361 * Added silc_server_relay_packet as general function to relay
4362 packet to arbitrary destination. This deprecates functions
4363 like _send_private_message_key, _relay_notify etc. Affected
4364 file is silcd/packet_send.[ch].
4366 Removed silc_server_send_key_agreement,
4367 silc_server_send_private_message_key and
4368 silc_server_packet_relay_notify functions from the file
4369 silcd/packet_send.[ch].
4373 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4374 server. Affected file silcd/packet_receive.[ch].
4376 * Implemented the KILL command to the client. Implemented the
4377 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4378 Affected files lib/silcclient/command[_reply].c and
4379 lib/silcclient/client_notify.c. Implemented the KILL notify
4380 printing in the user inteface.
4382 * Fixed a lot silc_parse_nick memory leaks from the client
4383 library in the file lib/silcclient/command.c.
4385 * Changed the silc_server_send_notify_on_channels's `sender'
4386 argument from SilcSocketConnection to SilcClientEntry to
4387 check the sender as entry and not as connection object and not
4388 to send to the client provided as argument. The affected file
4389 is silcd/packet_send.[ch].
4391 * The notify packets that are destined directly to the client used
4392 to not to be processed by the server. Now changed that and the
4393 server processes all notify packets. After relaying the packet
4394 to the client the notify packet is processed in the server.
4396 * The silc_server_free_client_data now checks whether there is
4397 pending outgoing traffic for the client and purges the data to
4398 the network before removing the client entry.
4400 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4403 an client is killed from the SILC Network. Updated the protocol
4406 Added new function silc_server_send_notify_killed to the
4407 silcd/packet_send.[ch].
4409 * Added function silc_server_packet_relay_notify to relay notify
4410 packets that are destined directly to a client. In this case
4411 the server does not process the notify packets but merely relays
4412 it to the client. Affected file silcd/packet_send.[ch].
4414 Added also silc_server_packet_process_relay_notify to check
4415 whereto relay the notify. Affected file is
4416 silcd/packet_receive.[ch].
4418 * Implemented the KILL command to the server.
4422 * Added the backup schema desgined last fall to the protocol
4423 specs for everyone to see. The specification is in the
4424 *-spec-xx.txt draft and the packet type definitions for the
4425 backup routers is in *-pp-xx.txt draft. Thusly, added also
4426 new packet type SILC_PACKET_CELL_ROUTERS.
4428 * A big security problem in the implementation discovered. The
4429 signoff of an client did not cause new channel key generation
4430 which it of course should've done. The channel keys must be
4431 always re-generated when client leaves (or signoffs) the channel.
4432 The silc_server_remove_from_channels funtion now handles
4433 the channel key re-generation.
4435 * Added `sender' argument to the silc_server_send_notify_on_channels
4436 to not to send the client provided as argument. Affected file
4437 silcd/packet_send.[ch].
4439 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Implemented OPER and SILCOPER commands into the server and
4444 * Added silc_auth_verify and silc_auth_verify_data to verify
4445 the authentication directly from the authentication payload.
4446 It supports verifying both passphrase and public key based
4447 authentication. Affected file lib/silccore/silcauth.[ch].
4449 * Added `hash' field to the SilcIDListData structure. It is the
4450 hash negotiated in the SKE protocol. Affected file is
4453 * Slight redesigning of the SilcAuthPayload handling routines.
4454 Do not send SilcPKCS but SilcPublicKey as argument.
4456 * Implemented the public key authentication support to the
4457 serverconfig. The public key is loaded from the provided path
4458 and saved as authentication data to void * pointer. Thus,
4459 changed the unsigned char *auth_data to void *auth_data;
4461 * Fixed SHUTDOWN command to send the reply before the server
4462 is shutdown. :) Affected file silcd/command.c.
4464 * Fixed fatal bug in CONNECT command. The hostname was invalid
4465 memory and server crashed. Affected file silcd/command.c.
4467 * Fixed fatal bug in CLOSE command. The server_entry became
4468 invalid but was referenced later in the command. Affected file
4471 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Fixed fatal bug in failure packet handling. Server ignored
4474 the failure and thus crashed when it came.
4478 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4480 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4481 that the command may be executed only once in (about) 2 seconds.
4482 The old SILC_CF_LAG flag is same but allows command bursts up
4483 to five before limiting.
4485 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4486 server code. Various commands now includes the CF_LAG_STRICT
4487 flag to disallow any kind of miss-use of the command.
4489 * Fixed the silc_buffer_unformat to not to allocate any data
4490 if the length of the data is zero. It used to allocate the
4491 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4493 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Changed the format of AdminConnection configuration section
4496 in the server. Added username of the admin to the format.
4497 Affected files silcd/serverconfig.[ch].
4499 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4500 to return admin configuration data by host, username and/or
4503 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Implemented WHOWAS command to the server. Added the functions:
4507 silc_server_command_whowas_parse,
4508 silc_server_command_whowas_send_reply,
4509 silc_server_command_whowas_from_client and
4510 silc_server_command_whowas_from_server
4512 * Added <Client ID> argument to the WHOWAS command reply. Updated
4513 the protocol specs accordingly.
4515 * Implemented WHOWAS command and command_reply to the client
4518 Implemented the WHOWAS printing on the user interface.
4520 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Added new argument to the WHOWAS command reply, the real name.
4523 It is an optional argument. Updated the protocol specs.
4525 * Added SilcIDCacheDestructor callback that is registered when
4526 the SilcIDCache is allocated. The callback is called when
4527 an cache entry in the ID Cache expires, or is purged from the
4528 cache. Added into lib/silccore/idcache.[ch].
4530 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4531 to destruct the client entries when the cache entry expires.
4532 Other ID Cache's in server and in the client library ignores
4535 * If the ID Cache entry's `expire' field is zero then the entry
4536 never expires. Added boolean `expire' argument to the
4537 silc_idcache_add function in the lib/silccore/idcache.[ch].
4538 If it is TRUE the default expiry value is used.
4540 * Added silc_server_free_client_data_timeout that is registered
4541 when client disconnects. By default for 5 minutes we preserve
4542 the client entry for history - for WHOWAS command.
4544 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4546 * Added support to the server to enforce that commands are not
4547 executed more than once in 2 seconds. If server receives
4548 commands from client more frequently, timeout is registered
4549 to process the commands. Affected file silcd/command.c.
4550 Added new function silc_server_command_process_timeout.
4552 * Changed NICK_NOTIFY handling in client library to check that
4553 if the client's nickname was changed, so there is no need to
4554 resolve anything from the server.
4556 * Removed error printing from the WHOIS and IDENTIFY commands.
4557 If error occurs then it is ignored silently in the client library.
4558 The application, however, may map the received error to
4559 human readable error string. The application currently maps
4560 the NO_SUCH_NICKNAME error to string.
4562 * Made the command status message public to the application. Moved
4563 them from lib/silcclient/command_reply.c to
4564 lib/silcclient/command_reply.h. The application can map the
4565 received command status to the string with the
4566 silc_client_command_status_message function.
4568 * Added check to the server to check that client's ID is same
4569 as the Source ID in the packet the client sent. They must
4572 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Added dist-bzip hook to the Makefile.am to make bzip2
4575 compressed distributions.
4577 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Server now enforces the maximum length for the nickname and
4580 the channel as protocol specification dictates. 128 bytes for
4581 nickname and 256 bytes for channel name.
4583 * Moved the WHOIS printing to the application. The client libary
4584 does not print out the WHOIS information anymore, the application
4585 must do it. Renamed silc_client_command_reply_whois_print to
4586 the silc_client_command_reply_whois_save.
4588 The client's idle time is also sent to the application now, and
4589 the idle is shown on screen.
4591 * Added silc_client_command_reply_identify_save to save the
4592 received IDENTIFY entries.
4594 * Do not check for channel private keys in message sending and
4595 reception if the channel does not have the PRIVKEY mode set.
4596 Affected file lib/silclient/client_channel.c.
4598 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4601 just surfaced after chaning the JOIN procedure.
4603 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Added silc_client_get_clients_by_list to get client entries
4606 from Client ID list, that is returned for example by JOIN
4607 and USERS command replies. The application should use this
4608 function for example when JOIN command reply is received to
4609 resolve the clients already on the channel (library does not
4610 do that anymore as USERS command reply is not used in the JOIN
4611 procedure anymore). Affected files lib/silcclient/silcapi.h and
4612 lib/silcclient/idlist.c.
4614 * JOIN command reply and USERS command reply returns now SilcBuffer
4615 pointers instead of unsigned char pointers when returning
4616 the client list and mode list.
4618 * Added <Client ID> argument to the JOIN command reply, mainly
4619 for the server to identify for which client the command was
4620 originally sent. Updated protocol specs accordingly.
4622 * Added SilcDlist private_key pointer to the SilcChannelEntry
4623 in the client to support the channel private keys. Affected
4624 file is lib/silcclient/idlist.h.
4626 * Added SilcChannelPrivateKey argument to the function
4627 silc_client_send_channel_message so that application can choose
4628 to use specific private ke if it wants to. If it is not provided,
4629 the normal channel key is used, unless private keys are set.
4630 In this case the first (key that was added first) is used
4631 as the encryption key.
4633 * Implemented the support for channel private key handling.
4634 Implemented the following functions:
4636 silc_client_add_channel_private_key,
4637 silc_client_del_channel_private_keys,
4638 silc_client_del_channel_private_key,
4639 silc_client_list_channel_private_keys and
4640 silc_client_free_channel_private_keys
4642 Affected file lib/silcclient/client_channel.c.
4644 * Added the support for the private keys in the channel message
4645 sending and encryption and in the message reception and
4646 decryption. Affected funtions are
4647 silc_client_send_channel_message and silc_client_channel_message.
4649 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * Added SKE's key verify callback to the client library's
4652 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4654 * Removed the statement that server (or router) must send USERS
4655 command reply when joining to the channel so that the client
4656 knows who are on the channel. Instead, the client list and
4657 client's mode list is now sent in the JOIN command reply to the
4658 client who joined channel. This is better solution.
4660 * Added function silc_server_get_users_on_channel and function
4661 silc_server_save_users_on_channel to the silcd/server.[ch].
4663 * Removed function silc_server_command_send_users from the
4666 * Do not show topic on the client library anymore. The topic is
4667 sent in the command reply notify to the application and the
4668 application must show the topic now.
4670 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Added client searching by nickname hash into the IDENTIFY and
4673 WHOIS commands in the server as they were clearly missing from
4674 them. Affected file is silcd/command.c.
4676 * Fixed a bug in private message receiving in the client library.
4677 The remote ID was freed and it wasn't supposed, now it is
4680 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Minor fix to the channel payload; allocate the data area, as it
4683 needs to be of specific length.
4685 * If the key agreement port is zero then the operating
4686 system will define the bound port. Affected files are
4687 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4689 * Added new function silc_channel_payload_decrypt into the file
4690 lib/silccore/silcchannel.[ch].
4692 * Moved the channel message etc, check from silc_packet_decrypt
4693 to applications. The library calls now a generic
4694 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4695 when the packet is either normal or special. This was done to
4696 allow more wide range of checking that was not allowed when
4697 the code was in library. Now applications can do virtually any
4698 checks to the packet and return to the library the decision how
4699 the packet should be processed. Affected files are
4700 lib/silccore/silcpacket.[ch].
4702 Added silc_server_packet_decrypt_check to the server and
4703 silc_client_packet_decrypt_check to the client library.
4705 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4706 to send with specified source and destination information.
4708 * Channel message delivery between routers was broken after the
4709 channel key distribution was fixed earlier. The channel key
4710 was used be to distributed to other routers as well which is not
4711 allowed by the protocol. Now this is fixed and channel keys
4712 really are cell specific and the channel message delivery between
4713 routers comply with the protocol specification.
4715 * Fixed various commands in server to check also the global list
4716 for the channel entry and not just the local list. The affected
4717 file silcd/command.c.
4719 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * Added assert()s to buffer formatting and unformatting routines
4722 to assert (if --enable-debug) when error occurs. Affected
4723 file: lib/silcutil/silcbuffmt.c.
4725 * Changed to auto-reconnect to check whether the remote host is
4726 router and register the re-connect timeout if it is. It used
4727 to check that whether we are normal server, but router must do
4728 auto-reconnect with another router as well. Affected file
4731 * Removed the [<key len>] option from CMODE command as the cipher
4732 name decides the key length, nowadays. See the defined ciphers
4733 from the protocol specification.
4735 * Added [<hmac>] option to the CMODE command to define the HMAC
4736 for the channel. Added SILC_CMODE_HMAC channel mode.
4738 * Added [<hmac>] option for the JOIN command so that user can
4739 select which HMAC is used to compute the MACs of the channel
4742 * Added Hmac field to the Channel Message Payload. The integrity
4743 of plaintext channel messages are now protected by computing
4744 MAC of the message and attaching the MAC to the payload. The
4745 MAC is encrypted. Now, it is clear that this causes some
4746 overhead to the size of the packet but rationale for this is that
4747 now the receiver can verify whether the channel message decrypted
4748 correctly and also when private keys are set for the channel the
4749 receiver can decrypt the packet with several keys and check from
4750 the MAC which key decrypted the message correctly.
4752 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4753 lib/silccrypt/silccipher.[ch].
4755 * Added silc_hash_len to return the digest length into the
4756 lib/silcrypt/silchash.[ch].
4758 * Rewrote parts of Silc Channel Payload interface in the
4759 lib/silccore/silcchannel.[ch]. The encode function now also
4760 encrypts the packet and parse function decrypts it.
4762 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Fixed a minor formatting bug in the SKE's key material processing.
4765 It actually might have processed the keys wrong way resulting
4768 * Redefined the mandatory HMAC algorithms and added new algorithms.
4769 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4770 and hmac-md5 truncated to 96 bits. The mandatory is now
4771 hmac-sha1-96. Rest are optional (including the one that used
4772 to be mandatory). Rationale for this is that the truncated HMAC
4773 length is sufficient from security point of view and can actually
4774 make the attack against the HMAC harder. Also, the truncated
4775 HMAC causes less overhead to the packets. See the RFC2104 for
4778 * Added new [hmac] configuration section. The SKE used to use
4779 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4780 is of course wrong. The official names that must be proposed in
4781 the SKE are the ones defined in the protocol specification
4782 (hmac-sha1-96 for example). The user can configure any hmac
4783 using any hash function configured in the [hash] section. At
4784 least, the mandatory must be configured.
4786 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4788 * Added HMAC list to the SKE proposal list. It has now both
4789 hash algorithm list and HMAC list. This makes the protocol
4790 incompatible with previous versions. The SKE now seems to work
4791 the way it is supposed to work, for the first time actually.
4793 * Defined plain Hash algorithms to the protocol specification.
4796 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * Implemented support for key agreement packets into the server.
4799 Added functions silc_server_key_agreement and
4800 silc_server_send_key_agreement. Other than these functions,
4801 server has nothing to do with this packet.
4803 * Added support for private message key packets into the server.
4804 Added functions silc_server_private_message_key and
4805 silc_server_send_private_message_key.
4809 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4810 called in the protocol's final callback instead in the END
4811 protocol state. This makes a little more sense and in the same
4812 time in client we can use the same protocol routines for normal
4813 key exchange and to key agreement packet handling as well.
4815 * Added to both client's and server's KE protocol context the
4816 SilcSKEKeyMaterial pointer to save the key material. We will
4817 bring the key material to the protocol's final callback by doing
4818 this. The final callback must free the key material.
4820 * Added SKE's packet_send callback into client's KE protocol
4821 context so that the caller can choose what packet sending function
4822 is used. This way we can use different packet sending when
4823 doing normal SKE when doing key agreement packet handling (in
4824 the key agreement packet handling we do not want to encrypt
4827 * Implemented the responder side of the key agreement routines
4828 in the client. The client can now bind to specified port and
4829 accept incoming key negotiation. The key material is passed
4830 to the application after the protocol is over.
4832 * Implemented the processing of incoming Key Agreement packet
4833 in the client. Added function silc_client_key_agreement to
4836 * Implemented the intiator side of the key agreement routines
4837 in the client. The client can now initiate key agreement with
4838 another remote client. The key material is passed to the
4839 application after the protocol is over.
4841 * Created client_keyagr.c to include all the key agreement
4844 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4845 SILC_TASK_CALLBACK except that it is not static.
4847 * Created client_notify.c and moved the Notify packet handling
4848 from the client.[ch] into that file.
4850 * Created client_prvmsg.c and moved all private message and
4851 private message key routines from the client.[ch] into that file.
4853 * Create client_channel.c and moved all channel message and
4854 channel private key routines from the client.[ch] into that file.
4856 * Changed silc_client_get_client_by_id_resolve to resolve with
4857 WHOIS command instead of IDENTIFY command, in the file
4858 lib/silclient/idlist.c.
4860 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Implemented the SKE's responder side to the Client library.
4864 * When FAILURE is received to the protocol do not trust it
4865 blindly. Register a timeout to wait whether the remote closes
4866 the connection as it should do it, only after that process the
4867 actual failure. This was changed to both client and server.
4869 * Added client_internal.h to include some of the structures
4870 there instead of client.h in lib/silcclient/.
4872 * Added function silc_task_unregister_by_callback to unregister
4873 timeouts by the callback function.
4875 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4877 * Some "Incomplete WHOIS info" errors has been appearing on the
4878 log files. Took away the entry->userinfo check from WHOIS
4879 reply sending. The entry->userinfo is now " " if client did not
4880 provide one. I thought this was fixed earlier but something
4881 is wrong still. Let's see if the error still appears.
4883 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Fixed a minor bug in the login when the channel key is
4886 re-generated in the server. It used to generate the key in
4887 wrong order and thus caused problems in the channel traffic.
4889 * Fixed a minor bug in channel key distsribution after
4890 KICK command. The key was not sent to the router even though
4893 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Added silc_ske_process_key_material_data as generic routine
4896 to process any key material as the SILC protocol dictates. The
4897 function is used by the actual SKE library but can be used by
4898 applications as well. This relates to the private message keys
4899 and the channel private keys since they must be processed the
4900 same way the normal SILC session keys. The protocol dictates
4901 this. Affected files: lib/silcske/silcske.[ch].
4903 Added also silc_ske_free_key_material to free the
4904 SilcSKEKeyMaterial structure.
4906 * Defined silc_cipher_set_key function to set the key for
4907 cipher without using the object's method function. The affected
4908 files: lib/silccrypt/silccipher.[ch].
4910 * Implemented silc silc_client_add_private_message_key,
4911 silc_client_add_private_message_key_ske,
4912 silc_client_del_private_message_key,
4913 silc_client_list_private_message_keys and
4914 silc_client_free_private_message_keys functions in the
4917 Added functions silc_client_send_private_message_key to send
4918 the Private Message Key payload and silc_client_private_message_key
4919 to handle incoming Private Message Key payload.
4921 * Added Cipher field to the Private Message Key payload to set
4922 the cipher to be used. If ignored, the default cipher defined
4923 in the SILC protocol (aes-256-cbc) is used.
4925 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4927 * Removed lib/silcclient/ops.h file.
4929 Redefined parts of the SILC Client Library API. Created new
4930 file silcapi.h that deprecates the ops.h file and defines the
4931 published Client Library API. Defined also private message key
4932 API and channel private key API into the file.
4934 This is the file that the application must include from the
4935 SILC Client Library. Other files need not be included by
4936 the application anymore.
4938 * Added new key_agreement client operation callback and also
4939 defined the Key Agreement library API for the application.
4941 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4944 is used by clients to request key negotiation between another
4945 client in the SILC network. If the negotiation is started it
4946 is performed using the SKE protocol. The result of the
4947 negotiation, the secret key material, can be used for example
4948 as private message key.
4950 Implemented the Key Agreement payload into the files
4951 lib/silccore/silauth.[ch].
4953 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Redefined ciphers for the SILC protocol. Added some new ciphers
4956 and defined the key lengths for the algorithms. Changed the
4957 code accordingly. The default key length is now 256 bits.
4959 * Fixed SKE key distribution function silc_ske_process_key_material
4960 when the key length is more than 128 bits. The default key
4961 length in SILC is now 256 bits.
4963 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4964 to indicate unsupported algorithm.
4966 * Renamed rijndael.c to aes.c and all functions as well.
4968 * Fixed a long standing channel key setting bug in client library.
4969 Weird that it has never surfaced before.
4971 * Fixed bug in channel deletion. If the entire channel is removed
4972 then it must also delete the references of the channel entry
4973 from the client's channel list as the client's channel entry and
4974 the channel's client entry share same memory.
4976 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Implemented CONNECT and SHUTDOWN commands in the client.
4980 * Implemented CLOSE command to the client.
4982 * Added the function silc_idlist_find_server_by_name into the
4983 files silcd/idlist.[ch].
4985 Added the function silc_idlist_find_server_by_conn into the
4986 files silcd/idlist.[ch].
4988 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * DIE command was renamed to SHUTDOWN. Updated the both code
4993 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4994 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4996 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4999 * Added function silc_server_create_connection function to create
5000 connection to remote router. My server implementation actually
5001 does not allow router to connect to normal server (it expects
5002 that normal server always initiates the connection to the router)
5003 so the CONNECT command is only good for connecting to another
5006 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5009 or some other client was kicked from the channel.
5011 Implemented the handling of the notify type to both client
5014 Implemented silc_server_send_notify_kicked to send the KICKED
5015 notify. It is used to send it to the server's primary router.
5017 * Implemented the KICK command into server and client.
5019 * Added `query' argument to the silc_idlist_get_client function
5020 to indicate whether to query the client from server or not if
5023 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5024 to indicate that the client is not channel founder.
5028 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Removed the rng context from SilcPacketContext structure and
5031 changed that the packet routine uses the Global RNG API.
5033 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5035 * Added support for quit message that client can "leave" on the
5036 channel when it quits the SILC. It is ditributed inside the
5037 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5039 Added silc_server_free_client_data that will take the
5040 signoff message as argument.
5042 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5044 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Updated parts of the protocol specification to keep it up
5049 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5052 payloads in one packet.
5054 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5055 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5056 use now the new List flag.
5058 * Also deprecated the following packet types: REPLACE_ID,
5059 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5061 * Added list support for Notify packet in server.
5063 * Added silc_server_send_notify_channel_change to send the
5064 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5065 the silc_server_send_replace_id.
5067 * Added silc_server_send_notify_nick_change to send the
5068 NICK_CHANGE notify type. Deprecates the function
5069 silc_server_send_replace_id.
5071 * Added silc_server_send_notify_join to send the JOIN notify type.
5072 Deprecates the function silc_server_send_new_channel_user.
5074 * Added silc_server_send_notify_leave to send LEAVE notify type.
5075 Deprecates the function silc_server_send_remove_channel_user.
5077 * Added silc_server_send_notify_cmode and
5078 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5079 types. Deprecates the silc_server_send_set_mode function.
5081 * Added SERVER_SIGNOFF notify type to indicate that server has
5082 quit. This means that all clients on the channel from that
5083 server will drop. This can be also used when netsplit happens.
5085 Deprecated REMOVE_ID packet type since it is not needed anymore
5088 Added silc_server_send_notify_server_signoff to send the
5089 SERVER_SIGNOFF notify type. Deprecates the function
5090 silc_server_send_remove_id.
5092 Added also silc_server_send_notify_signoff to send the
5093 SIGNOFF notify type.
5095 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5096 SILC protocol from this day on. Changed the protocol
5097 specification as well.
5099 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5100 notify type. It is used between routers to notify about
5101 topic changes on a channel.
5103 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5106 * Partly updated the protocol specification to comply with the
5107 changes now made. It is still though a bit outdated.
5109 * The JOIN notify type now takes one extra argument <Channel ID>.
5110 The packet used to be destined to the channel but now the
5111 JOIN type may be sent as list thus it is impossible to
5112 destine it to any specific channel. By adding this argument
5113 it is again possible.
5115 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5117 * Added CREDITS file. The CHANGES and CREDITS file will appear
5118 in the distribution as well.
5120 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5123 types in the server's silcd/packet_receive.c.
5125 * Implemented CMODE and CUMODE to work in router environment.
5127 * Fixed minor encoding and decoding buglet from the
5128 lib/silccore/silcmode.c.
5130 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5133 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5135 * Changed all SilcConfigServer* and silc_config_server* to
5136 SilcServerConfig* and silc_server_config*, respectively.
5139 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Associated the ID (client or server ID) to the Authentication
5142 Payload to avoid any possibility of forging. Updated the
5143 protocol specification and the code accordingly.
5145 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * The RSA key length is now save to the RsaKey context in the
5148 key generation process in lib/silccrypt/rsa.c. The key length
5149 is now used to figure out the maximum size of the block allowed
5150 to be encrypted/signed.
5152 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5153 is equivalent to the silc_mp_mp2bin but does not allocate any
5156 * Changed silc_mp_mp2bin API to take length argument. If it is
5157 non-zero then the buffer is allocated that large. If zero, then
5158 the size is approximated using silc_mp_sizeinbase, which however
5161 * Created Global RNG API which is global RNG that application can
5162 initialize. After initializing, any routine anywhere in the
5163 code (including library) can use RNG without allocating a new
5164 RNG object. This was done to allow this sort of use of the
5165 RNG in code that has no chance to allocate RNG object. All
5166 applications currently allocate this and many routines in the
5167 library use this. Affected file lib/silccrypt/silcrng.[ch].
5169 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5170 it to use the Global RNG API.
5172 * Defined Authentication Payload into protocol specification that
5173 is used during SILC session to authenticate entities. It is
5174 used for example by client to authenticate itself to the server
5175 to obtain server operator privileges.
5177 Implemented this payload into the lib/silccore/silcauth.[ch].
5178 Implemented also routines for public key based authentication
5179 as the new protocol specification dictates.
5181 Moved definitions of different authentication methods from
5182 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5184 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5185 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5186 silc_pkcs_verify_with_hash functions into the file
5187 lib/silccrypt/silcpkcs.[ch].
5189 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * The client entry's userinfo pointer must be always valid.
5192 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5193 will fail since it requires the userinfo. Now, the userinfo
5194 is allocated as "" if actual userinfo does not exist. Actually,
5195 it must exist and it is totally Ok to drop client connections
5196 that does not announce the userinfo. However, we will make
5197 this workaround for now.
5199 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5200 to return the remote port by socket.
5202 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5205 SILC_SERVER_PENDING_EXEC and added an new macro
5206 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5207 data or when error occurs while processing the pending command.
5209 Added new argument `destructor' into silc_server_command_pending
5210 and to the SilcServerCommandPending object. This destructor is
5211 now called after calling the pending callback or if error occurs
5212 immediately. If error occurs the actual pending callback won't
5213 be called at all - only the destructor. The destructor may be
5214 NULL if destructor is not needed.
5216 All this applies for client library code as well. Similar
5217 changes were made there as well for the pending commands.
5219 In the client, the application must now allocate the
5220 SilcClientCommandContext with the silc_client_command_alloc
5223 * Added reference counter to the SilcServerCommandContext. Added
5224 function silc_server_command_alloc and silc_server_command_dup
5227 Same type of functions added to the client library for the same
5230 * Removed the cmd_ident from IDListData away since it is now
5231 global for all connections. It is the command identifier used
5232 in command sending and with pending commands. The affected file
5235 * Added reference counter to the SilcSocketConnection objecet to
5236 indicate the usage count of the object. The object won't be
5237 freed untill the reference counter hits zero. Currently only
5238 server uses this, and client ignores it. The client must be
5239 set to use this too later. The affected files are
5240 lib/silccore/silcsockconn.[ch]. Added also the function
5241 silc_socket_dup to increase the reference counter.
5243 This was mainly added because it is possible that the socket
5244 is removed underneath of pending command or other async
5245 operation. Now it won't be free'd and proper DISCONNECTING
5246 flags, etc. can be set to avoid sending data to connection that
5247 is not valid anymore.
5249 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5250 the connection. After that it sets SILC_SET_DISCONNECTED.
5251 It is, however, possible that the socket data is not still freed.
5252 The silc_server_packet_process now checks that data is not
5253 read or written to connection that is DISCONNECTED. The socket
5254 get's freed when the reference counter hits zero.
5256 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Changed the client operation API: channel_message operation's
5259 `sender' is now the client entry of the sender, not the nickname
5260 and the `channel' is the channel entry, not the channel name.
5262 In the private_message operation the `sender' is now also the
5263 client entry of the sender not the nickname.
5265 Affected file is lib/silcclient/ops.h and all applications
5266 using the client operations.
5268 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Moved the calling of ops->connect() from connect_to_server_final
5271 into receive_new_id functin since that is the point when the
5272 client is actually allowed to send traffic to network. The
5273 affected file is lib/silcclient/client.c.
5275 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5277 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5278 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5279 (if needs broadcasting) instead of broadcasting the packets one
5280 by one which would make a burst in the network traffic.
5282 * Added `broadcast' argument to the functions in silcd/server.[ch]
5283 silc_server_create_new_channel[_with_id] to indicate whether
5284 to send New Channel packet to primary router.
5286 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Added new function into the silcd/server.[ch] files:
5289 silc_server_create_new_channel_with_id to create new channel with
5290 already existing Channel ID.
5292 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5293 lib/silccore/silcpacket.h. This packet is used t send list of
5294 Set Mode payloads inside one packet. Server uses this to set
5295 the modes for the channels and clients on those channels, that it
5296 announced to the router when it connected to it. The protocol
5297 specification has been updated accordingly.
5299 * The silc_server_new_channel did not handle the packet coming
5300 from normal server as it normally does not send that. However,
5301 when it announces its channels it does send it. Implemented
5302 the support for that.
5304 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5305 into the file lib/silccore/id.h.
5307 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Fixed memory leaks in the functions silc_idlist_del_client,
5310 silc_idlist_del_channel and silc_idlist_del_server in the file
5311 silcd/idlist.c. All of those leaked like a sieve.
5313 * Fixed some small memory leaks in the client's function
5314 silc_client_notify_by_server.
5316 * Added functions into silcd/server.c: silc_server_announce_clients,
5317 silc_server_announce_channels and silc_server_announce_server.
5318 These functions are used by normal and router server to announce
5319 to its primary router about clients, channels and servers (when
5320 router) that we own. This is done after we've connected to the
5323 These functions effectively implements the following packet types:
5324 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5325 and SILC_PACKET_NEW_ID_LIST.
5327 * Added new functions into the silcd/packet_receive.[ch]:
5328 silc_server_new_id_list, silc_server_new_channel_list and
5329 silc_server_new_channel_user_list to handle the incoming
5330 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5332 * Added support of changing Channel ID in the function
5333 silc_server_replace_id. If the server that announces a channel
5334 to the router already exists in the router (with same name but
5335 with different Channel ID), router is responsible to send
5336 Replace ID packet to the server and force the server to change
5337 the Channel ID to the one router has.
5339 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5340 client that the Channel ID has been changed by the router. The
5341 normal server sends this to the client. Client must start using
5342 the new Channel ID as the channel's ID.
5344 Implemented handling of this new type into lib/silcclient/client.c
5345 into the function silc_client_notify_by_server.
5347 * Added new function silc_idlist_replace_channel_id into the files
5348 silcd/idlist.[ch] to replace the Channel ID.
5350 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Call silc_server_command_identify_check always when processing
5353 the IDENTIFY command in silcd/command.c
5355 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5357 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5358 send keepalive packets. The packet can be sent by clients,
5359 servers and routers.
5361 Added function silc_socket_set_heartbeat into the file
5362 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5363 If not set, the heartbeat is not performed. The actual
5364 heartbeat is implemented in the low level socket connection
5365 library. However, application is responsible of actually
5368 Added silc_server_send_heartbeat to send the actual heartbeat
5369 packet into silcd/packet_send.[ch]. Server now performs
5370 keepalive with all connections.
5372 * Added silc_task_get_first function into lib/silcutil/silctask.c
5373 to return the timeout task with shortest timeout. There was a bug
5374 in task unregistration that caused problems. TODO has been
5375 updated to include that task system must be rewritten.
5377 * The client library will now resolve the client information when
5378 receiving JOIN notify from server for client that we know but
5379 have incomplete information.
5381 * Rewrote parts of silc_server_remove_from_channels and
5382 silc_server_remove_from_one_channel as they did not remove the
5383 channel in some circumstances even though they should've.
5385 * Encryption problem encountered in server:
5387 The LEAVE command used to send the Channel Key packet to the
5388 router immediately after generating it. However, the code
5389 had earlier sent Remove Channel user packet but not immediately,
5390 ie. it was put to queue. The order of packets in the router
5391 was that Channel Key packet was first and Remove Channel User
5392 packet was second, even though they were encrypted in the
5393 reverse order. For this reason, MAC check failed. Now, this
5394 is fixed by not sending the Channel Key packet immediately but
5395 putting it to queue. However, this is more fundamental problem:
5396 packets that are in queue should actually not be encrypted
5397 because packets that are sent immediately gets encrypted
5398 actually with wrong IV (and thus MAC check fails). So, packets
5399 that are in queue should be encrypted when they are sent to
5400 the wire and not when they put to the queue.
5402 However, the problem is that the current system has not been
5403 designed to work that way. Instead, the packet is encrypted
5404 as soon as possible and left to the queue. The queue is then
5405 just purged into wire. There won't be any fixes for this
5406 any time soon. So, the current semantic for packet sending
5409 o If you send packet to remote host and do not force the send
5410 (the packet will be in queue) then all subsequent packets to the
5411 same remote host must also be put to the queue. Only after the
5412 queue has been purged is it safe again to force the packet
5415 o If you send all packets immediately then it safe to send
5416 any of subsequent packets through the queue, however, after
5417 the first packet is put to queue then any subsequent packets
5418 must also be put to the queue.
5420 Follow these rules and everything works fine.
5422 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Added new function silc_server_remove_clients_by_server to
5425 remove all client entries from ID list when the server connection
5426 is lost. In this case it is also important to invalidate all
5427 client entires as they hold the invalid server entry. This
5428 fixes fatal bug when server has lost connection and will reconnect
5431 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Made some sanity checks to silc_server_daemonise like to check
5434 whether the requested user and group actually exists.
5436 * Added sanity check to SKE's silc_ske_responder_finish to check
5437 that the public and private key actually is valid.
5439 * Invalidate the client's nickname when receiving Replace ID
5440 packet and the Client ID is being replaced. This means that the
5441 server will query the nickname if someone needs it (client)
5444 * Sort the ID Cache in client library when the ID Cache data
5445 has changed (needs sorting).
5447 * Do not allow for SILC client to create several connections to
5448 several servers. The client does not support windows right now
5449 and generating multiple connections causes weird behaviour.
5451 Irssi-silc client does support windows and can handle several
5452 connections without problems, see: www.irssi.org and SILC plugin.
5454 * Fixed some places where client was added to the IDList. The
5455 rule of thumb is following (in order to get everything right):
5456 If the client is directly connected local client then the
5457 `connection' argument must be set and `router' argument must be
5458 NULL to silc_idlist_add_client function. If the client is not
5459 directly connected client then the `router' argument must
5460 bet set and the `connection' argument must be NULL to the
5461 silc_idlist_add_client function.
5463 * The funtion silc_server_packet_send_local_channel actually did
5464 not check whether the client was locally connected or not. It
5465 does that now. Fixed a bug related to LEAVE command.
5467 * Fixed Remove Channel User payload parsing bug in server's
5468 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5470 * The server's silc_server_save_channel_key now checks also the
5471 global ID list for the channel as it might not be in the local
5472 list. Fixed a bug related to LEAVE command.
5474 * Is this the end of the [<unknown>] buglet that has been lurking
5475 around for a long time? A little for loop fix in server's
5476 silc_server_command_whois_parse that is used by both IDENTIFY
5477 and WHOIS command. At least, this was a clear bug and a cause
5478 of one type of [<unknown>] buglet.
5480 * WHOIS and IDENTIFY commands call the function
5481 silc_server_command_[whois/identify]_check function even if
5482 we are not router server.
5484 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Added --with-gmp configuration option. If set the GMP
5487 is always compiled in the SILC source tree. If not set then
5488 it is checked whether the system has the GMP3 installed. If
5489 it has then the GMP won't be compiled (the system's headers
5490 and library is used), if it doesn't have it then the GMP is
5491 compiled in the SILC source tree.
5493 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Changed RSA private exponent generation to what PKCS #1
5496 suggests. We try to find the smallest possible d by doing
5497 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5498 not security fix but optimization.
5500 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * Added new config entry [Identity] to fork the server and run
5503 it as specific user and group. A patch from Bostik.
5505 * Imported Dotconf configuration library into lib/dotconf.
5506 This will be used to create the SILC configuration files later.
5507 It will appear in the distsribution after this commit.
5509 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * A big code auditing weekend happening. Auditing code for
5512 obvious mistakes, bugs and errors. Also, removing any code
5515 Removed files for being obsolete:
5517 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5518 inline in the file lib/silcutil/silcbuffer.h)
5520 o lib/silcutil/silcbufutil.c (the header has inline versions)
5522 Changed code to fix possible error conditions:
5524 o The buffer formatting routines now check that the destination
5525 buffer really has enough space to add the data. This applies for
5526 both buffer formatting and unformatting
5527 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5528 unformatting was changed to accomodate following rules:
5529 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5530 sent to the function while XXX_*STRING will not allocate or copy
5531 the data into the buffer. Instead it sets the pointer from the
5532 buffer into the pointer sent as argument (XXX_*STRING used to
5533 require that the pointer must be allocated already). This change
5534 makes this whole thing a bit more consistent and more optimized
5535 (note that the data returned in the unformatting with XXX_*STRING
5536 must not be freed now). The routines return now -1 on error.
5538 o Tried to find all code that use buffer_format and buffer_unformat
5539 and added return value checking to prevent formatting and
5540 especially unformatting errors and possible subsequent fatal
5543 o Changed ske->x and ske->KEY to mallocated pointers in
5544 lib/silcske/silcske.h. Fixed possible data and memory leak.
5546 o Added return value checking to all *_parse* functions. Fixed
5547 many memory leaks as well.
5549 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5550 so that buffer overflows would not happen. All code now also
5551 checks the return value as it can fail.
5553 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Added reconnection support to server if the normal server looses
5556 its connection to the router (for example if router is rebooted).
5557 The server performs normal reconnection strategy implemented
5558 to the server. Affected file silcd/server.c.
5560 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * Added new packet type SILC_PACKET_SET_MODE that is used to
5563 distribute the information about changed modes (for clients,
5564 channels and clients channel modes) to all routers in the
5565 network. Updated the protocol specification accordingly.
5567 Added functions into silcd/packet_send.c and
5568 silcd/packet_receive.c: silc_server_send_set_mode,
5569 silc_server_set_mode.
5571 Added new files silcmode.[ch] into lib/silccore that implements
5572 the encoding and decoding of Set Mode Payload. Added new type
5573 SilcSetModePayload. Moved the definitions of different modes
5574 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5576 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5578 * Oops, a little mistake in server's connection authentication
5579 protocol. The protocol is not ended with FAILURE but with
5580 SUCCESS if the authentication is Ok. :) Affected file is
5583 * Implemented NICK_CHANGE notify handling in server in the file
5584 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5585 the local clients on the channel. After the changing nickname
5586 in router environment snhould work and the [<unknown>] nickname
5587 should appear no more.
5589 The silc_server_replace_id function that receives the Replace ID
5590 payload now sends the NICK_CHANGE notify type also in the file
5591 silcd/packet_receive.c
5593 * Changed WHOIS and IDENTIFY command to support the maximum amount
5594 of arguments defined in protocol specs (3328 arguments). This
5595 fixed a bug that caused problems when there were more than three
5598 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Added extra parameter, command identifier, to the
5601 silc_client_send_command so that explicit command identifier
5604 Changed that ID list routines uses specific command identifier
5605 when sending WHOIS/IDENTIFY requests to the server so that they
5606 can be identified when the reply comes back.
5608 Affected files lib/silcclient/command.[ch],
5609 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5611 * Added `sender' argument to silc_server_packet_send_to_channel
5612 to indicaet the sender who originally sent the packet to us
5613 that we are now re-sending. Ignored if NULL. Affected file
5614 silcd/packet_send.[ch].
5616 * Added some server statistics support in silcd/server_internal.h
5617 SilcServerStatistics structure and around the server code. Also
5618 send some nice statistics information when client is connecting
5621 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Fixed channel ID decoding in server's JOIN command reply in
5624 silcd/command_reply.c
5626 * Fixed braodcasting of replace ID payload to not to send it if
5627 we are standalone server in silcd/packet_receive.c.
5629 * Fixed all channel message sending routines to not to send
5630 packets to clients that has router set, since they are routed
5631 separately in the same function earlier. Affects file
5632 silcd/packet_send.c and all channel packet sending functions.
5634 * In USERS reply, res_argv[i] are not allocated, the table
5635 is allocated. Thus changed that free the table, not its
5638 * In server's whois_check and identify_check if the client is
5639 locally connected do not send any WHOIS commands - they are not
5642 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5644 * Fixed some minor bugs in client when sending WHOIS command. The
5645 arguments was in wrong order.
5647 * Removed statis function add_to_channel from server in
5648 silcd/command.c that was previously used with the joining but
5651 * Tested USERS command in router environment successfully with two
5652 routers, two servers and two clients.
5654 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5656 * Reorganized the USERS command and command reply in client library
5657 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5658 When the command is given by user we register a pending command
5659 callback that will reprocess the command after the reply has been
5660 received from the server. When reprocessing the packet we then
5661 display the information. Thus, the USERS information is displayed
5662 now in the command callback instead of in the command reply
5663 callback. The processing of the command is same as previously
5664 when server has sent the command reply in the JOINing process.
5666 * Added to USERS command in silcd/command_reply.c to join the client,
5667 we didn't use to know about, to the channel after we've created
5668 a client entry for it. Also, for clienet we did know already still
5669 check whether it is on the channel or not and add it if not.
5671 * Removed silc_server_command_join_notify as the function and its
5674 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Changed the client's pending command handling to the same as the
5677 server's pending command handling. It is also now possible to
5678 execute command reply functions from other command reply
5679 function as the function callbacks for commands and command
5680 replies are one and same. The pending commands are not static
5681 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5682 in client connection context. Thus, pending commands are server
5683 connection specific as it is convenient.
5685 Changed the function silc_client_command_pending and
5686 silc_client_command_pending_del and added new function
5687 silc_client_command_pending_check. Removed the
5688 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5691 * Added cmd_ident, current command identifier, to the client
5692 connection context in lib/silcclient/client.h to keep track on
5693 command identifiers used in command sending. Client's command reply
5694 function handling now supports the mandatory command identifiers.
5696 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5697 funtions in client to fully support pending command callbacks.
5699 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5700 as one of the arguments to the application in the command reply
5703 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5704 before first releasing SILC but came back. Now it is removed again
5705 and should come back nomore. The FORWARDED flag was used only
5706 by the JOINing procedure by forwarding the command packet to router.
5707 Now, the JOINing procedure has been changed to more generic (due
5708 to various router environment issues) and FORWARDED is not needed
5709 anymore for anything. The protocol specification is yet to be
5712 Now, removed silc_server_packet_forward from server and the flag
5713 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5715 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5717 * Renamed NAMES command to USERS command. The NAMES was named that
5718 due to historical reasons. Now it is renamed. Also, rewrote
5719 parts of the USERS command. The nickname list is not sent anymore
5720 by the server. Only Client ID and mode lists are sent in the USERS
5721 command. Changed this also to the protocol specification.
5723 The client now resolves the names and stuff after it receives
5724 the USERS list from the server when joining to the channel.
5726 * WHOIS and IDENTIFY commands has been changed to support multiple
5727 Client ID's per command. One can now search for multiple users
5728 in the network by sending only one WHOIS or IDENTIFY command.
5729 Changed the code and the protocol specifications.
5731 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5732 uses silc_server_command_whois_parse to parse the request. */
5734 * If normal server, do not parse the WHOIS and IDENTIFY requests
5735 before sending it to the router. Saves some time.
5737 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Fixed JOIN command on client library. Wrong number of arguments
5740 used to crash the client.
5742 * Added silc_server_channel_has_global function to check whether
5743 channel has global users or not.
5745 * Added silc_server_channel_has_local function to check whether channel
5746 has locally connected clients on the channel.
5748 * The silc_server_remove_from_one_channel now checks whether the
5749 channel has global users or not after given client was removed from
5750 the channel. It also checks whether the channel has local clients
5751 on the channel anymore. If it does not have then the channel entry
5752 is removed as it is not needed anymore.
5754 * The silc_server_notify now checks on JOIN notify whether the joining
5755 client is one of locally connected or global. If it is global then
5756 the channel has now global users on the channel and that is marked
5757 to the channel entry. Also, it now saves the global client to
5758 global list who is joining and JOINs it to the channel. This is
5759 for normal server, that is.
5761 Changed silc_server_send_notify_on_channel,
5762 silc_server_packet_relay_to_channel and
5763 silc_server_packet_send_to_channel check if we are normal server
5764 and client has router set (ie. global client) do not send the
5765 message to that client, as it is already routed to our router.
5767 * Implemented LEAVE notify type handling in silc_server_notify
5770 * Tested LEAVE command in router environment successfully. Tested
5771 with two routers, two servers and two clients.
5775 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5777 * Implemented SIGNOFF notify type handling in silc_server_notify
5780 * silc_server_remove_id now removes the client entry from all channels
5781 it has joined and thusly sends SIGNOFF notify type.
5783 * Rewrote the NAMES list generation in server by removing two excess
5784 loops. The lists are created now inside one loop.
5786 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * silc_server_remove_channel_user checks now also global list
5789 for channel and client.
5791 * silc_server_new_channel_user checks now both local and global
5792 list for channel and client. Fixed a bug in client id decoding.
5793 Used to decode wrong buffer.
5795 * silc_server_channel_message checks now both local and global
5796 list for channel entry.
5798 * Tested channel joining (hence JOIN) in router environment
5799 successfully. Tested with two routers, two servers and two
5802 * Tested channel message sending in router environment successfully.
5804 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Added silc_server_save_channel_key into server.[ch] to save the
5807 received channel key in Channel Key payload processing. It is
5808 also used in JOIN command reply handling.
5810 Equivalent function silc_client_save_channel_key added into
5811 client.[ch] into client library.
5813 * Changed JOIN command reply to send information whether the channel
5814 was created or not (is existing already) and the channel key
5815 payload. Changed protocol specs accordingly.
5817 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5818 the request was sent by ID and not by nickname. Crashed on
5821 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5823 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5824 now correctly save the received data.
5826 * silc_server_free_sock_user_data now notifies routers in the
5827 network about entities leaving the network.
5829 At the same time implemented functions silc_server_remove_id
5830 and silc_server_send_remove_id to receive and send REMOVE_ID
5831 packets. The packet is used to notify routers in the network
5832 about leaving entities. The ID removed will become invalid in
5835 * Added function silc_idlist_del_server into server. Removes and
5836 free's server entry from ID list.
5838 * silc_server_private_message function now checks, if we are router,
5839 that the destination ID really is valid ID, naturally.
5841 * In router when NEW_ID packet is received (for new client) the
5842 hash of the Client ID is saved in the ID Cache but the
5843 client->nickname is set to NULL, instead of putting the hash
5846 IDENTIFY command now also checks that client->nickname must be
5847 valid. If it is not if will request the data from the server who
5848 owns the client. Added new function
5849 silc_server_command_identify_check.
5851 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5852 to set the command to already allocated Command Payload.
5854 * Tested private message sending in router environment with two
5855 routers, two servers and two clients. Fixed minor bugs and now
5858 * Fixed segfault from client's NAMES command. Used to crash if
5861 * Forwarded packets must not be routed even if it is not destined
5862 to the receiver. Changed server code comply with this.
5864 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Added `require_reverse_mapping' boolean value to ServerParams
5867 structure. If TRUE (not default) the server will require that
5868 the connecting host has fully qualified domain name.
5870 If the reverse mapping is not required and hostname could not be
5871 found the IP address is used as hostname.
5873 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Implemented version string checking to both client and server.
5876 The check is incomplete currently due to the abnormal version
5877 strings used in development version of SILC.
5879 * Changed all command functions in server to use the new
5882 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * Changed char *data to unsigned char *data in ID Cache system to
5885 support binary data as ID Cache data. Changed code to support
5886 binary data in lib/silccore/idcache.c.
5888 * Renamed silc_server_packet_relay_command_reply to
5889 silc_server_command_reply as it is normal packet receiving
5890 function. Rewrote the function to accept command replys for
5891 servers and not only for clients.
5893 * Mark remote router always as registered server if we are connecting
5894 to it. Otherwise, commands sent by the router to us are ignored.
5896 * All ID List find routines now returns the ID Cache Entry pointer
5897 as well if requested.
5899 * WHOIS command works now in router environment, tested with two
5900 routers, two servers and two clients.
5902 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5903 in router environment (as it is almost equivalent to WHOIS) but
5904 hasn't been tested thoroughly. Added new functions:
5906 silc_server_command_identify_parse
5907 silc_server_command_identify_send_reply
5908 silc_server_command_identify_from_client
5909 silc_server_command_identify_from_server
5911 * Disabled route cache adding because adding two different ID's with
5912 same IP replaces the old cache entry thus giving wrong route.
5913 The entry->router->connection is always the fastest route anyway
5914 so route cache may not be needed. Of course, new routes maybe
5915 established after receiving the ID when the entry->router->connection
5916 might not be anymore the most optimal.
5918 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * Add route cache for received ID for fast routing.
5922 * Added silc_server_packet_route to route received packet on router
5923 that is not destined to us.
5925 * Renamed silc_server_get_route to silc_server_route_get.
5927 * Added id_string and id_string_len fields into SilcServer to
5928 include encoded ServerID for fast comparing without excess
5929 encoding of the ID's.
5931 * Cleaned up WHOIS command on server side. Added following static
5934 silc_server_command_whois_parse
5935 silc_server_command_whois_check
5936 silc_server_command_whois_send_reply
5937 silc_server_command_whois_from_client
5938 silc_server_command_whois_from_server
5940 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5941 arguments in command replies. All command functions should be
5942 updated to use this macro.
5944 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Minor typo fixes on command reply handling on server.
5948 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Added silc_server_command_add_to_channel internal routine to add
5951 the client to the channel after router has created the channel and
5952 sent command reply to the server.
5954 * Added generic silc_server_send_command to send any command from
5957 * Use static buffer with ID rendering instead of duplicating data.
5959 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Fixed a channel user mode bug when joining to a channel server gave
5962 everybody channel founder rights, oops.
5964 * We mark ourselves as the router of the incoming server connection
5965 if we are router ourselves. This way we can check in some packet
5966 sending functions whether it is locally connected server. For
5967 incoming router connections we put NULL.
5969 * For router sending packets locally means now always sending the
5970 packet cell wide; to local clients and local servers. For normal
5971 server sending packet locally means sending it to only local
5974 * Fixed the JOIN command to really work in router environment. If the
5975 channel is created it is always created by the router. Router is
5976 also responsible of making the initial joining to the channel,
5977 sending JOIN notify to the sending server and distributing
5978 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5979 does not exist server doesn't do anything else but forward the
5980 command to the router which performs everything.
5982 * Added silc_server_send_channel_key function to send the Channel Key
5985 * Added silc_server_create_channel_key to create new channel key. The
5986 channel key is now re-generated everytime someone joins or leaves
5987 a channel, as protocol dictates. Note: channel->key_len is the
5990 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5993 packet_receive.[ch] to separate packet sending and receiving
5994 routines. The server.[ch] now includes everything else including
5995 actual packet processing (writing and reading data) and other
5998 Renamed silc_server_private_message_send_internal to
5999 silc_server_send_private_message. The routine is still though
6000 used only to relay private messages as server does not send
6001 private messages itself.
6003 Renamed silc_server_new_channel to silc_server_create_new_channel
6004 and added new function sicl_server_new_channel that handles the
6005 incoming New Channel packet. Added also new sending function
6006 silc_server_send_new_channel to send New Channel Payload.
6008 * Added new function silc_server_notify to process incoming notify
6009 packet to the server/router. Server may then relay the notify
6010 to clients if needed.
6012 * Added new function silc_server_new_channel_user to process incoming
6013 New Channel User packet. Router will redistribute the packet and
6014 send JOIN notify to its local clients and locally connected servers
6015 if needed. Normal server will send JOIN notify to its local client
6016 on same channel when received this packet. Added also corresponding
6017 sending function silc_server_send_new_channel_user to sent the
6020 * Added boolean route argument to send_notif_to_channel and
6021 packet_send_to_channel functions to attempt to route the packet
6022 if it is TRUE and send only locally if it is FALSE.
6024 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * silc_server_replace_id now broadcasts the received replace ID
6027 packet if it is not broadcast packet already. The router must
6028 broadcast to inform other routers about changed ID.
6030 * Added backpointer to server's router into SilcServer context in
6031 silcd/server_internal.h.
6033 * Fixed silc_server_packet_broadcast to send correct broadcast
6036 * The channel key is now distributed to the local client as soon
6037 as it is received from the router (in router environment) so that
6038 no other packet may be sent for the channel until client has
6041 * silc_server_remove_channel_user now broadcasts the received
6042 Remove Channel User packet if it is not broadcast packet already.
6043 The router must broadcast to inform other routers about removed
6046 * Added users field into SilcPacketContext that is a reference count
6047 of the context. One can increase the reference count by calling
6048 silc_packet_context_dup which is now changed to just increase the
6049 reference count instead of duplicating the data. The reference
6050 count is decresed by calling silc_packet_context_free that will
6051 free the data after the reference count hits zero.
6053 For now on the packet context and everything allocated into it
6054 (including the raw packet from network) must be freed by calling
6055 the new silc_packet_context_free function. Added also new function
6056 silc_packet_context_alloc that must be used now to allocate the
6057 context. This also means that if a routine is asynchronous from
6058 silc_[client/server]_packet_parse_type the packet context must
6059 be duplicated by calling silc_packet_context_dup. Otherwise it
6060 gets free'd after silc_[client/server]_packet_parse_type returns.
6061 Also, one must remember that if packet is duplicated then its
6062 reference count must be decresed by calling the free function as
6063 many times as it was duplicated.
6065 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6066 from both client and server.
6068 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * Made joining to a channel working in router environment.
6072 * Cleaned up JOIN command on server side and create function
6073 silc_server_command_join_channel internal routine to make the
6076 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Changed silc_command_pending list to SilcDList. Also, added
6079 `ident' field to SilcServerCommandPending structure to identify
6080 the reply and to call correct callback.
6082 Added silc_server_command_pending_check function to replace the
6083 corresnponding macro. The silc_command_pending list is not
6086 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6087 to set identifier to previously allocated Command Payload. It
6088 is used to set identifier for command when resending Command
6091 * Added silc_command_payload_encode_payload to encode Command
6092 Payload buffer from SilcCommandPayload structure.
6094 * Added silc_argument_payload_encode_payload to encode Argument
6095 payload buffer from SilcArgumentPayload structure.
6097 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6099 * Changed WHOIS command to support router connection on server side.
6100 The whois request is always sent to router unless the server is
6101 standalone server. After server has received the reply from the
6102 router will it send the reply to the client.
6104 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6105 broadcast received broadcast packet. The function is used only
6106 by router. The broadcast packet is always sent to the router's
6109 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6110 render given ID to printable string, for log files for example.
6112 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Made basic router to router connections working. At least they
6115 can now connect to each other but nothing really works the way
6116 they are supposed - yet.
6118 * Added new initiator token to RouterConnection configuration
6119 file in silcd/serverconfig.[ch]. It is used to tell whether we
6120 are the initiator to the remote router or whether we'll expect
6121 the other end to connect.
6123 * Moved registering of listener task to silc_server_init, hence
6124 the server starts listenning as soon as it is run, even if it
6125 does not have connections to other routers. Let's see how well
6128 * Changed default connection retry timeouts for more suitable in
6131 * Removed cipher and such arguments from silc_idlist_add_client
6132 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6133 Added new function silc_idlist_add_data to add the keys and stuff
6136 * Added SilcIDListData structure and added it to SilcClientEntry
6137 and SilcServerEntry as their first field in the structure. This
6138 way we can explicitly cast the ID entries to the SilcIDListData
6139 structure and get common data for the entries. In past, we had
6140 to first check what type of connection it is and then cast it to
6141 correct ID entry type. Now, we can directly cast the opaque
6142 pointer to the SilcIDListData (no matter what ID entry it actually
6143 is) and get the data needed.
6145 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6148 in some circumstances even if threre were timeout tasks, though not
6149 IO tasks, but tasks anyway. Now fixed.
6151 * Defined SilcServerConnection structure to hold connection specific
6152 stuff about directly connected servers and routers. The definition
6153 is currently in silcd/server_internal.h. I thought about having
6154 a bit more important role fro this struct but for now it is used
6155 only when connecting to other server (or router actually).
6157 * Added connecting retry support in server when connecting to
6158 router(s). The retry feature implement exponential backoff
6159 algorithm. Also, added SilcServerParams structure to hold default
6160 parameters for server. For now, it include these retry settings
6161 and are hard coded. After server is moded to be as Silc Server
6162 Library this structure will be more important.
6164 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Changed client librarys channel->clients table to SilcList and
6167 changed code accordingly.
6169 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Changed client's channel table to SilcList and changed code
6172 accordingly. Also changed SilcChannelClientEntry to include back-
6173 pointer to the channel so that client entry can use that structure
6174 as list as well and we have fast cross-reference to the channel.
6175 This change dramatically decreased the complexity of channel
6176 handling with client entry and vice versa (removed one extra
6177 loop when searching for channel entry from many functions).
6179 * Changed server->sim from table to SilcDList and changed code
6182 * NAMES command can now be used from user interface. It will show
6183 the user list on the channel, neatly.
6185 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6186 Code now saves realname of the user if it becomes available.
6188 * Renamed configure.in to configure.in.pre and made ./prepare
6189 script to automatically add correct version string to
6190 configure.in which it creates from configure.in.pre.
6192 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6194 * NAMES command reply now shows users mode with the nickname when
6197 * Moved silc_client_ch[u]mode[_char] functions from
6198 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6199 place sucks, they are utility functions and should be in some
6202 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6204 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6207 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * Added TRQ (efficient deque and list library) into lib/trq. This is
6212 a very good list library that is currently used in the SILC. Defined
6213 SilcList API over the library because I didn't like the API very
6214 much. See lib/trq/silclist.h for the API and examples of how to
6215 use the API. Fixed various places in the code to use the new
6216 SilcList API. The SilcList is meant for lists that has a structure
6217 already defined as a list. It is not suitable to add just some
6218 context to the list (in TRQ, the context is the list actually).
6220 So, I defined SilcDList that can be used for the purpose where
6221 predefined list structure does not exit. This can be used as
6222 such list. Now some context just can be added to the SilcDList.
6223 Currently this list is not used in the SILC just yet, though there
6224 are a lot places where this can replace dynamically allocated
6225 tables and I will fix these places, later, to use SilcDList.
6226 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6227 and use TRQ internally).
6229 Also fixed some annoying warning messages that the original TRQ
6230 code generated. Also minor changes to TRQ's Makefile.in.
6232 * Added support for querying by Client ID to both WHOIS and
6233 IDENTIFY commands into server, as required by the protocol.
6235 * Removed method function pointers from SilcBuffer structure. They
6236 weren't used to anything and just increased the context size for
6237 no good reason. This change also made silc_buffer_alloc and
6238 silc_buffer_free functions inline functions.
6240 * Disabled command flooding detection support until it's fixed so
6241 that it accepts commands in but does not execute them more than once
6244 * Added silc_net_localhost(), to return local hostname, into
6245 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6246 that must be initialized before calling silc_client_init.
6248 * Added new function: silc_server_send_notify_on_channels to send
6249 notify messages to all channels client has joined. It is assured
6250 that the message is sent only once per client.
6252 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6253 lib/silcutil/silcutil.[ch] as silc_format function. The new
6254 function is generic and is used by server as well, not only by
6255 the logging routines.
6257 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6258 the provided version string was not acceptable. Added new function:
6259 silc_ske_check_version into lib/silcske/silcske.h. The function
6260 must be implemented by the application (client or server) and it
6261 does not reside in the SKE library. The function checks the version
6262 string remote end sent.
6264 * Added back pointers (to opaque context and to SilcSocketConnection)
6265 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6267 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6268 duplicate packet context structure.
6270 * Changed `notify' client operation to send same arguments as client
6271 receives from server except for ID's. ID's are mapped to correct
6272 ID entry and that is returned. Also, if channel entry is not sent
6273 by server but the notify is for channel the channel entry is sent
6274 to application (otherwise application doesn't know that it is for
6275 channel (library gets it from packet's Destination ID)).
6277 * Added silc_client_remove_from_channels into client library to
6278 remove a client from all channels it has joined to. Used when
6279 received SIGNOFF notify from server. Added also new function
6280 silc_client_replace_from_channels to replace old ID entry with
6281 new ID entry on all channels. Used when received NICK_CHANGE
6284 * Fixed ID Cache list handling in silc_idlist_get_client in
6285 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6286 to get (or query) client by ID.
6288 * Updated TODO list.
6290 * Added connection authentication status message defined by the
6291 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6292 support for these into the code in client and server side.
6294 * Added generic function silc_client_send_command to send any command
6295 with variable argument list. Application should use this function
6296 to send commands if the command functions provided by the library
6297 does not suite for the application's user interface needs.
6299 * Added new `failure' client operation. Application is notified about
6300 received failure packet if client is executing a protocol. In this
6301 case the protocol's execution has failed.
6303 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6304 is required by the protocol.
6306 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6307 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6310 * Added status flag to SilcSKE object to indicate realtime status
6311 of the SKE protocol.
6313 * Application receives now exactly same command reply arguments as
6314 the library receives from server. However, if ID is received the
6315 corresponding ID entry is returned to the application (eg. Client
6316 ID is mapped to correct SilcClientEntry entry and that is returned).
6317 Changed command_reply client operation due to this change.
6319 * Changed all ID's in commands and in command replys as ID Payloads.
6320 Change affected both client and server side codes.
6322 All ID's sent in SILC network (with execption of ID's in SILC
6323 Packet header) are sent in ID Payload to support variable length
6326 * Server now notifies nick changes and notifies all clients on
6327 the channels about the new nickname (about the new Client ID,
6330 * Implemented CMODE command to change channel modes. Supports all
6331 channel modes defined by the protocol specs except ban and invite
6332 lists. (Also, private channel key mode is supported but support for
6333 setting private channel key in client is missing, thus, this mode
6334 has no effect on client side (except that server requires that the
6335 client uses private channel key and normal channel traffic does not
6338 Also, invite mode works per se, but INVITE command does not work
6339 yet correctly, so you can set channel as invite only channel but
6340 inviting clients to the channel does not work (it is yet to be
6341 thought what's the best way to do it).
6343 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6344 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6345 Implemented CUMODE command to change user's mode on the channel.
6346 Supports all modes defined by the protocol specs.
6348 * Added NAMES command reply to return users modes on the channel.
6350 * Removed unnecessary and slow ciphers from lib/silccrypt.
6352 * Set SO_KEEPALIVE option to connection sockets by default.
6354 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6356 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6357 redefined the Notify Payload into protocol specs.
6359 * Added silc_id_payload_parse_id to get ID directly from raw
6362 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6365 accept searching by Client ID as well.
6367 * Added support for LEAVE and SIGNOFF notify types in client library.
6369 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6370 to parse ID Payload from raw data.
6372 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6374 * Added flags parameter into silc_ske_assemble_security_properties
6375 function in lib/silcske/silcske.[ch].
6377 * Changed notify client operation to fit better for notify messages
6378 sent by server. The notify payload received from server is now
6379 passed to the application (after parsing it to SilcNotifyPayload).
6380 It is application's responsibility to retrieve the arguments
6381 from the payload and show the message the way it wants. The message
6382 sent by server is implementation specific.
6384 * Changed public keys to comply with the protocol specification.
6385 Old public keys are not supported anymore and are not compatible.
6387 * Removed nickname from Channel Payload as the latest draft removed
6388 it. The client must resolve the nickname from the NAMES command
6389 reply received when it joined the channel.
6391 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6393 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6395 * Fixed some errors in protocol specification drafts.
6397 * Created lib/silccore/silcnotify.c to implement Notify Payload
6398 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6399 generic payloads described by protocol specifications. The file
6400 includes implementations for ID Payload and Argument Payload.
6402 * Changed Command Payload implementation to use the new Argument
6403 Payload. Changed command_xxxx_payload to command_payload_xxxx
6404 to comply with SILC coding conventions.
6406 * Added suppport for Argument Payload handling in Notify Payload
6407 implementation as protocol requires it. Added the new support
6408 into server and client lib as well.
6410 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * Added support for multiple nicknames on same channel. [n] is
6413 added locally to the nickname if there are more than one same
6414 nicknames on the channel.
6416 * Server now sends all nicknames that matched WHOIS request.
6417 Client also shows the list received from server.
6419 * Added TOPIC command to client side. User can now set and show
6420 current topic on channel.
6422 * Added MOTD command to client and server. Also, server sends the
6423 motd when client connects to the server.
6425 * Changed version strings to comply ISO 8601.
6427 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Fixed protocol error handling in client library. It should now
6430 cope even if the SKE fails for some reason.
6432 * Made new protocol specification drafts for submitting to IETF.
6434 * Implemented TOPIC command to server in silcd/command.c.
6436 * Added two new notify types into lib/silccore/silcnotify.h:
6437 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6438 notify nickname change and topic setting/change on a channel.
6440 * API change of command_reply operation in client library. The
6441 application gets now the status type received from server as well.
6443 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6445 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6447 * Cras fixed and optimized the packet handling even further and
6448 it should work now. Minor change to the prototype of function
6449 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6451 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6453 * Added new function into lib/silcutil/silcschedule.[ch]:
6454 silc_schedule_with_fd to select() a specified fd. The function
6455 returns after timeout expires or data arrives or goes. The
6456 function is used by packet routines to wait that all data is
6457 received from network.
6459 * Fixed data reading from network in lib/silccore/silcpacket.c.
6460 The code now assures that all data is read from the fd and then
6461 continues packet processing. This was a bug fix since the code
6462 used to drop some data in some circumstances.
6464 * Added new function into lib/silcclient/client.[ch]:
6465 silc_client_start_key_exchange to start key exchange after
6466 connection has been established to server. The code internally
6467 now uses this funtion but its main purpose was to provide it
6468 for applications that perform their own connecting. After
6469 application has created a connection it merely calls this
6470 function to start the key exchange between client and server.
6471 The library takes care of everything else after that.
6473 Updated also lib/silcclient/README to explain the usage of
6476 * Do not send to application information that connection has
6477 been established. Application gets notified it by connect
6480 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6482 * Applied cras's patch to add silc_schedule_one function. The
6483 function runs scheduler once and returns.
6485 * Fixed the scheduler after cras messed it up. The timeout
6486 handling works now as it's supposed to work.
6488 * Added into lib/silccore/ silcnotify.h to include notify
6489 message types support. Changed silc_server_send_notify*
6490 functions, in server.[ch], to support those new notify types.
6491 Added the support for the notify types into client library,
6492 as well. Added new notify client operation into ops.h in
6495 * Changed silc_server_packet_send_to_channel to send normal
6496 packets instead of just channel message packets. The function
6497 is now used to send the notify packets to channels. It is not
6498 used to send channel message packets anymore, as server never
6501 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6502 va_arg()s as it seems to require it nowadays. I guess, if SILC
6503 is compiled with older va_arg() the new code should work anyway.
6505 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Splitted core library. Core library (lib/silccore) includes
6508 now only SILC protocol specific core (and common) components.
6509 Created new utility library (lib/silcutil) that includes more
6510 generic purpose stuff. The stuff for util library was taken
6511 from the old core library. This was minor and easy split.
6513 * Created SILC Client Library (lib/silcclient) that includes
6514 implementation of the SILC client without user interface. This
6515 was major move from silc/ directory. The code has been changed
6516 so that it is transparent towards the user interface. The
6517 silc/ directory includes now the same user interface as before
6518 and it uses the new client library. Read lib/silcclient/README.
6519 Basicly, the client library performs everything else related
6520 to SILC except user interface handling. Also, configuration
6521 files are considered to be part of user interface and library
6522 does not handle them.
6524 This change also changed a lot of structures, function naming etc.
6525 Most important change was that SilcClientWindow object was
6526 renamed to SilcClientConnection in the client library. Created
6527 also new file lib/silcclient/ops.h. Also added new files
6528 silc/local_command.[ch] and silc/client_ops.[ch].
6530 All these changes were made to make it easier for user interface
6531 designers to create what ever user interface for the SILC client
6534 It is also expected that the server will be moved to lib
6535 directory as well and SILC Server Library will be created;
6536 sometimes in the future.
6538 * Removed Local commands from lib/silccore/silccommand.h as
6539 they are application specific and new client library does not
6540 handle any of those anymore.
6542 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6543 old client implementation in silc/.
6545 * Added support for callback functions in SILC_LOG_* macros.
6546 Application can now set its own callbacks that will be called
6547 instead of using the default functions that will always print
6548 the debug messages to stderr (or stdout). Also, debugging can
6549 now be disabled by setting silc_debug to FALSE and re-enabled by
6550 setting it to TRUE. Note, that logging will still work even
6551 if debugging is disabled.
6553 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6554 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6555 silc_log_reset_debug_callbacks.
6557 * To enable debugging in silc client one must give now -d
6558 option on command line.
6560 * Changed silc_schedule_init to automatically allocate task queues
6561 if they are not allocated before calling it.
6563 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6565 * Added GMP 3.1 into math library.
6567 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6570 a channel in SILC network. The packet is used by servers and
6571 routers to notify other routers that user has left a channel.
6572 This little feature was missing until now. Added the feature
6573 to protocol specification as well.
6575 Added functions: silc_server_send_remove_channel_user and
6576 silc_server_remove_channel_user into server.[ch].
6578 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6579 lib/silccore/silcpacket.h. However, they are not implemented
6582 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * Fixed joining to a channel and sending channel messages
6585 between server and router. The channel message sending should
6586 now work inside a cell.
6588 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Fixed the private message sending between server and router.
6591 The private message sending should now work inside a cell.
6593 * Added silc_server_replace_id into server.[ch] to replace
6594 existing ID in the SILC network.
6596 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6597 and silc_idlist_replace_server_id into idlist.[ch] in server.
6599 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Fixed the server to server connections. Server can again now
6602 connect to router. Router to router connections probably does
6605 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6607 * Added dynamic protocol registering support. Now protocols can
6608 registered and unregistered on the fly. Patch by cras.
6610 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Added lib/contrib directory to hold routines that some platforms
6613 don't have but are needed by SILC.
6615 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6616 into lin/contrib to provide getopt() and getopt_long() for
6617 those who don't have it.
6619 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Added AWAY command to client. When away message is set and
6622 client receives a private message packet the client automatically
6623 replies to the sender with the away message.
6625 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6626 bug seemed to be the cause of recent problems when compiling
6629 * Added version detection support to SKE protocol specification
6630 and added the new changes to the SKE implementation as well.
6631 There were other minor changes in the SKE protocol as well.
6633 Many changes in lib/silcske/silcske.[ch] and in
6634 lib/silcske/payload.[ch].
6636 * Added ^U functionality, clear input line. Patch from cras.
6638 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6640 * Mainly small bugfixes on core library. Fixed some debugging
6641 logging and buffer overflow in silclog.c.
6643 * Updated config.sub and config.guess on the distribution tree.
6645 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Added command lagging support in server. Client may execute
6648 commands now only once in two seconds.
6650 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6652 * Optimized packet reception. MAC computation and checking is now
6653 also more optimized. A lot previously duplicated code is now
6654 used as generic by both client and server.
6656 * Fixed key pair generation in clientutil.c
6658 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6660 * Added into lib/silccore/silcbufutil.[ch] new function;
6661 silc_buffer_realloc.
6663 * Moved generic packet sending/encryption functions to
6664 lib/silccore/silcpacket.[ch] from client and server. Some
6665 rewriting of the functions.
6667 * Moved all generic packet reception/decryption functions to
6668 lib/silccore/silcpacket.[ch] from client and server. The
6669 packet processing is now much cleaner in both client and server.
6670 These were major changes in both client and server.
6672 * Created many common functions in server to do packet sending.
6673 Previously code were duplicated a lot, this has been removed
6676 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6678 * Rewrote major parts of the ID cache system. Don't know
6679 whether it is better now or not but at least the API is more
6682 * Major rewrite on ID cache stuff on client because of the ID
6683 cache API changes. Added idlist.c to client.
6685 * Also major rewrite on ID cache stuff on server as well.
6686 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6687 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6688 in hand, instead they are all put into the ID cache system now.
6689 All server_idlist_* routines uses ID cache now instead of
6690 traversing its own lists (those lists does not exist anymore).
6691 SilcIDList though still exists. Also, SilcXXXEntry's are
6694 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6696 * Finally made the SKE implementation compliant to the protocol
6697 specification. All mp integers are now binary encoded as
6698 opposed being HEX encoded.
6700 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6703 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6704 functions: silc_[encode/decode]_pem. Also added function
6705 silc_encode_pem_file to PEM encode with newlines ('\n') for
6708 * SILC public keys are now encoded either PEM or binary. Same
6709 option is for private keys as well. By default private keys
6710 are binary encoded and public keys PEM encoded. Silly HEX
6711 encoding were removed.
6713 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6714 function to create fingerprints.
6716 * Fixed a bug in SHA1; does not change the original data anymore.
6718 * Partly implemented INFO command on client and server side.
6719 Fixed CLEAR command. Changes to SERVER command; show current
6720 server(s) when giving command without arguments. Added
6721 VERSION command to client.
6723 * Added check to server that unregistered connections cannot
6724 execute commands (unless it is specificly allowed).
6726 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6728 * Fixed screen refresh.
6730 * Fixed channel joining bug from client. On some circumstances
6731 client tried to join to a channel it had already joined.
6733 * Added public key verification process into client's protocol.c.
6734 The client now verifies the public key from user and saves
6735 it into ~./silc/serverkeys/ directory.
6737 Added into: clientutil.[ch]: silc_client_verify_server_key.
6739 * Changed SKE protocol's silc_ske_initiator_finish function
6740 to accept callback function that verifies the received public
6741 key. Removed old silc_ske_verify_public_key function.
6743 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6745 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6746 silc_pkcs_private_key[_data]_set.
6748 * Made the password and public authentication more cleaner in
6749 server's protocol.c.
6751 * Removed historic and obsolete protocol `channel_auth' from
6752 both client and server.
6754 * Removed wrong way of sending command status messages from
6755 server to client in server's command.c. The old way violated
6756 protocol specification.
6758 Changes to silccore/silccommand.[ch]: removed
6759 silc_command_encode_status_payload -> not needed anymore,
6760 changed silc_command_encode_payload_va to accept extra
6761 argument on variable argument list. The argument type must
6762 now be provided to the function. Also, added new function:
6763 silc_command_encode_reply_payload_va which is same as
6764 normal command_encode_payload_va except command status type
6765 is provided as extra argument.
6767 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Added ~./silc directory handling. The directory includes the
6770 public and private keys for the client.
6772 Added silc_client_check_silc_dir, silc_client_create_identifier
6773 and silc_client_load_keys.
6775 * Implemented SILC protocol compliant public key. Added public
6776 and private key saving to and loading from files.
6778 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6779 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6780 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6781 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6782 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6784 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6785 silc_pkcs_load_[public/private]_key.
6787 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Added silc_server_get_route (route.[ch]) to get connection
6790 data for the fastest route for given ID.
6792 * Implemented INVITE command on client and server. The command
6793 were re-defined in the SILC Protocol Specification and the
6794 implementation now complies with the specification.
6796 * Implemented PING command on client and server.
6798 * Implemented NAMES command on client and server. The server side
6799 supports currently only normal server not router server yet.
6800 Some changes to NAMES definition in SILC protocol specification.
6802 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6804 * Implemented LEAVE command on client and server.
6806 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6807 again. This change was made to the protocol as well. Server
6808 should not violate the protocol specification anymore.
6810 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6813 was tested. SOCKS4 was not but should work anyway.
