1 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed silc_mp_sizeinbase to return the value correctly with
4 MPI. Affected file lib/silcmath/mp_mpi.c.
6 * Fixed the stop_server signal to correctly stop the scheduler
7 and gracefully stop the server when SIGTERM or SIGINT signals
8 are received. Affected file silcd/silcd.c.
10 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
12 * Simple handling of TERM and HUP signals. Also added some log
13 flushing call around. Affected file is
16 * Fixed small bugs in silclog.c. Now buffering output will take
17 effect after 10 seconds since startup: This will ensure that
18 no important startup messages are lost. Also output redirection
19 will preserve original format ([Date] [Type] message).
20 Affected file is lib/silcutil/silclog.c.
22 * Added two options to the config file, in the logging section:
23 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
24 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
26 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
28 * Do not print the warning about log files not being initialized
29 more than once to avoid excess logging. Affected file is
30 lib/silcutil/silclog.c.
32 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
33 the SIM copying in make install in Makefile.am.pre.
35 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
37 * Rewritten silclog APIs. Globally interesting changes follows:
38 silc_log_set_files() changed to silc_log_set_file().
39 silc_log_set_callbacks() changed to silc_log_set_callback().
40 ROBOdoc documented silclog header file.
41 SilcLogCb now returns bool to wether inihibit the default
42 handler or not (to keep the old behaviour return always TRUE).
43 The new APIs should also fix the problem of the
44 silcd_error.log file that was written in the current directory.
47 Log files streams will remain opened after silc_log_set_file()
48 call, means less CPU usage notably on high traffic servers.
49 File streams are now full buffered, and flushed to the disk
50 every 5 minutes, lesses HD activity and CPU usage.
51 Messages can be redirected, allowing admins to configure
52 one single logfile for all server messages.
53 the silc_log_quick global variable to activate fast-logging.
54 Affected files lib/silcutil/silclog.[ch]
56 * Changed some code to conform new silclog APIs. Affected
57 files are doc/example_silcd.conf.in, silcd/server.c
58 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
61 * Fixed a memory leak that could occur in some situations.
62 Affected file silcd/serverconfig.c.
64 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
66 * Added the silc_client_del_client to remove the client from
67 all channels as well. Affected file lib/silcclient/idlist.c.
69 * Fixed the client library to correctly remove the client
70 from all channels when the client entry is being destroyed.
71 Affected file lib/silcclient/client_notify.c, command.c.
73 * Added auto-nicking support to the client library. If the
74 applicatio now sets client->nickname it will be sent to the
75 server after connecting by the library. This way for example
76 SILCNICK (or IRCNICK) environment variables will have effect
77 and always change the nickname automatically to whatever
78 it is wanted. Affected file lib/silcclient/client.[ch].
80 * Renamed silc_server_command_bad_chars to the
81 silc_server_name_bad_chars and moved it to the
82 silcd/server_util.[ch]. Added also new function
83 silc_server_name_modify_bad to return nickname that
84 includes bad characters as new nickname without those
85 bad characters. This check and modify is now used in
86 silc_server_new_client when the username is initially set
87 as nickname, so it must be checked to be valid nickname.
88 Affected file silcd/packet_receive.c.
90 * The nickname length is now taken from the packet for real
91 and not trusted to strlen() since it clearly can return
92 wrong length for nickname including bad characters. This
93 also applies to channel names. Affected file silcd/command.c.
95 * Removed the lib/silcsilm/modules directory. Modules are now
96 compiled into the lib/silcsim. Fixed the copying of the
97 modules to follow symbolic links in Makefile.am.pre.
99 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
101 * Fixed silc_string_regexify list creation. Fixes bugs with
102 BAN and INVITE commands in server. The affected file is
103 lib/silcutil/unix/silcunixutil.c.
105 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
107 * Removed the command destructor entirely from the server's
108 command and command reply routines. It is not needed, and
109 its usage was buggy and caused crashes. Affected files are
110 silcd/command[_reply].[ch].
112 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
114 * Cancel protocol and NULL sock->protocol if timeout
115 occurred during protocol. Affected file silcd/server.c.
117 * Cancel protocol timeouts always before calling the final
118 callback, to assure that after final callback is called
119 no other state will be called for the protocol anymore.
120 Affected file silcd/protocol.c.
122 * Print error log if incoming connection configuration could
123 not be found. Affected file silcd/server.c.
125 * Fixed JOIN command to correctly save the founder mode
126 to the client on normal SILC server, when the channel
127 was created by the router. Affected file silcd/command.c.
129 * Fixed LIST command (hopefully) to send correct reply
130 packets. Affected file silcd/command.c.
132 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
134 * The silc_packet_receive_process now returns FALSE if the
135 read data was invalid packet, and TRUE if it was ok.
137 The server now checks that if unauthenticated connection
138 sends data and its processing fails the server will close
139 the connection since it could be a malicious flooder.
141 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
143 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
145 * Make sure the warning about error opening a log file is
146 printed only once and not everytime it fails (produces
147 too much useless log). Affected file lib/silcutil/silclog.c.
149 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
151 * Made the silc_server_daemonise() function more readable.
152 Affected file silcd/server.c.
154 * Pid file is now optional, the user may comment it out from
155 the config file. Removed define SILC_SERVER_PID_FILE, we
156 don't need a default any longer. Affected file
157 configure.in.pre, lib/Makefile.am.pre.
159 * Make some use of the pid file. The server now dies at startup
160 if it detects a valid pid file on his path. The server would
161 die anyway in this circumstance, because of the bind() failure.
162 Affected file silcd/silcd.c.
164 * No longer compiling lib/dotconf.
166 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
168 * Fixed JOIN command parsing not to crash. Affected file
169 lib/silcclient/command.c.
171 * Fied the NICK_CHANGE notify to add the new client entry
172 even it is resolved. This removes an <[unknown]> nick
173 thingy bug in the client. Affected file is
174 lib/silcclient/client_notify.c.
176 * Do not try to allocate 0 bytes (efence does not like it)
177 in lib/silccore/silccomand.c when encoding payload.
179 * Do not take IRCNICK as nickname in Irssi SILC client since
180 it is not possible to set nickname before hand connecting
181 the server (TODO has an entry about adding auto-nicking
184 * Changed the silc_server_command_pending to check whether
185 there already exists an pending entry with the specified
186 command, command identifier and pending callback. This is
187 to fix IDENTIFY and WHOIS related crashes that may register
188 multiple pending commands with same identifier. Affected
189 file silcd/command.c.
191 * Fixed the server to reconnect to the router even if it
192 was already reconnecting and EOF was received. This to
193 fix a possibility that the server wouldn't ever try to
194 auto-reconnect to the router. Affected file silcd/server.c.
196 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
198 * Fixed the server's password authentication to use the
199 length of the locally saved password, and not the one
200 sent in the packet. Affected file silcd/protocol.c.
202 * Fixed same password authentication problem in the
203 Authentication Payload handling routines in
204 lib/silccore/silcauth.c.
206 * Yet another password authentication problem fixed with
207 channel password handling in silcd/command.c.
209 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
211 * If first character of string in silc_parse_userfqdn is '@'
212 then do not parse it. Affected file is
213 lib/silcutil/silcutil.c.
215 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
217 * Fixed minor bug in IDENTIFY command reply sending, which
218 caused various weird problems during JOIN when it was
219 resolving names for users. Affected file silcd/command.c.
221 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
223 * Fixed the IDENTIFY command reply sending to chech better valid
224 clients. It was possible to send incomplete list of replies.
225 Affected file silcd/command.c.
227 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
229 * Added silc_client_command[s]_[un]register functions now to
230 dynamically register the commands in client library. Removed
231 the static table of commands. This allows the client library
232 to call commands without causing the application to know about
233 what commands library has called.
235 Removed the INFO command reply kludge to detect when the command
236 was called by library. Now library use its own command reply
237 function for INFO command.
239 Added function silc_client_command_call to call a command.
240 Application can use it to call command, not access the structure
243 Now all commands that are sent by the client library (not
244 explicitly sent by application) use own command reply functions.
246 Affected files around lib/silcclient/ and in
247 irssi/src/silc/core/.
249 * Fixed the WHOIS command reply sending to chech better valid
250 clients. It was possible to send incomplete list of replies.
252 Fixed the WHOIS and IDENTIFY to send the request to router
253 if normal server did not do it and did not find any results.
255 Affected file silcd/command.c.
257 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
259 * Moved the internal data from SilcClient context into its
260 own file, not accesible to application. Affected files
261 lib/silcclient/client.h and lib/silcclient/client_internal.h,
262 and other files in client library.
264 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
266 * Added doc/examples installation target in Makefile.am.pre.
269 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
271 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
272 commands the found client entry will be removed from the
273 cache, after notifying application about the error. Affected
274 file lib/silcclient/command_reply.c.
276 * Changed the /MSG to check for exact nickname user gave, and
277 not let `nick' match `nick@host' if it is only one found. Now,
278 user must type the exact nickname (like nick@host2) even if
279 there are no more than one same nicks found. This is to avoid
280 a possibility of sending nickname to wrong nickname since
281 `nick' could match `nick@host'. Affected file is
282 irssi/src/core/silc-servers.c.
284 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
286 * Do not print "you are now server operator" or similar when
287 giving /away command. Affected files are
288 irssi/src/silc/core/client_ops.c, silc-servers.h.
290 * Made the silc_server_command_pending_error_check to send
291 the same command reply payload it received back to the
292 original sender of the command. This way all arguments
293 that was received by the server will be received by the
294 client too. Affected file silcd/command.c.
296 * Added the silc_idcache_add to return the created cache entry
297 to a pointer. Affected file lib/silccore/silcidcache.[ch].
299 * Add global clients to expire if they are not on any channel.
300 This is because normal server will never know if they signoff
301 if they are not on any channel. The cache expiry will take
302 case of these entries. This is done by normal servers only.
303 The affected files are silcd/command_reply.c,
304 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
306 * If server receives invalid ID notification for WHOIS or
307 IDENTIFY and the ID exists in the lists, it is removed.
308 Affected file silcd/command_reply.c.
310 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
311 in client then client entry that it matches is searched and
312 the nickname is printed on the screen for user. Affected
313 file irssi/src/silc/core/client_ops.c.
315 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
317 * Use cache entry expire time in the LIST command reply to
318 purge old entries from the cache after the LIST command
319 reply has been received. This way we don't have non-existent
320 entries in the cache for too long. Affected file is
321 silcd/command_reply.c.
323 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
325 * If we are normal server, and we've not resolved client info
326 in WHOIS or IDENTIFY from router, and it is global client,
327 we'll check whether it is on some channel. If it is not
328 then we cannot be sure about its validity and will resolve it
329 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
330 file silcd/command.c.
332 * Search channel by name (if possible) rather than by ID
333 in IDENTIFY command's command reply. Affected file is
334 silcd/command_reply.c.
336 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
338 * Distribute to the channel passphrase in CMODE_CHANGE notify.
339 Updated specs and implemented it. Affected file silcd/command.c,
340 silcd/packet_send.c and silcd/packet_receive.c.
342 * Implemented the <founder auth> payload handling in the JOIN
343 command. If provided all conditions for channel joining
344 except requirement to provide correct passphrase can be
345 overrided by the channel founder. Updated the protocol specs.
346 Affected file silcd/command.c.
348 Added support for founder auth in JOIN command in client
349 library. Fixed the parsing of the JOIN command now to support
350 all options as they should be. The affected file is
351 lib/silcclient/command.c.
353 * Optimized the WHOIS and IDENTIFY commands to send the request
354 to router only if it includes nicknames or other names. If
355 they include only IDs then check the local cache first before
356 routing. Affected file is silcd/command.c.
358 * Added channels topic announcements. Affected file is
359 silcd/packet_receive.c and silcd/server.c.
361 * Fixed the silc_server_send_notify_topic_set to really destine
362 the packet to channel. Affected file silcd/packet_send.c.
364 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
365 library. Affected file lib/silcclient/client_notify.c.
367 * Added UMODE announcements. Affected file silcd/server.c.
369 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
371 * Memory leak fixes in:
373 lib/silcutil/silcsockconn.c
374 lib/silcske/silcske.c
377 lib/silccrypt/silcpkcs.c
378 lib/silccore/silccommand.c
379 lib/silccore/silcidcache.c
384 * ROBOdoc documented the lib/silcske/groups.h file and a
385 bit changed the interface for better.
387 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
389 * Update the client entry context in the ID cache after
390 nick change. Affected file lib/silcclient/command.c.
391 Fixes the CUMODE command when regaining founder privileges,
392 and a little WHOIS problem.
394 * Fixed silc_net_gethostbyname to correctly call the
395 inet_ntop. Affected file lib/silcutil/silcnet.c.
397 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
399 * Added IPv6 support checking to the configure.in.pre, added
400 also --enable-ipv6 option to override the check. Affected
401 file configure.in.pre.
403 * The silc_thread_create now calls the start function
404 directly if threads support is not compiled in. Removes
405 ugly #ifdef's from generic code. Affected files are
406 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
408 * Added silc_net_gethostby[name/addr]_async to asynchronously
409 resolve. Affected files are lib/silcutil/silcnet.[ch].
411 * Added support for rendering IPv6 based server, client and
412 channel IDs. Affected file lib/silcutil/silcutil.c.
414 * Added support for creating IPv6 based server IDs. Affected
415 file is silcd/serverid.c.
417 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
419 * Added silc_net_gethostby[addr/name] into the
420 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
421 routines. Added silc_net_is_ip[4/6]. Affected file is
422 lib/silcutil/unix/silcunixnet.c. All routines that take
423 address as argument now supports both IPv4 and IPv6 addresses.
425 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
427 * Fixed LIST command reply sending in server. Affected file
430 * Server now sends the kicker's client ID in the KICK notify
431 to the kicked client. Affected file silcd/command.c.
433 * The client library now parses the kickers client ID and
434 UI displays it. Affected files lib/silcclient/client_notify.c
435 and irssi/src/silc/core/silc-channels.c, module-formats.c.
437 * Made all payload parsing function prototypes consistent.
438 They all take now const unsigned char * and uint32 pair as
439 the payload data instead of SilcBuffer. Changes all around
440 the source tree. Other unsigned char* -> const unsigned char*
441 changes around the tree as well.
443 * Optimized SFTP client and server packet sending not to
444 allocate new buffer for each packet but to recycle the
445 first allocated buffer. Affected files are
446 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
448 * Optimized the SFTP client to use SilcList instead of
449 SilcDList for requests, because it is faster. Affected file
450 is lib/silcsftp/sftp_client.c.
452 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
453 into lib/silccore/silcid.[ch].
455 Renamed silcpayload.[ch] into silcargument.[ch].
457 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
459 * If client entry is deleted with active key agreement
460 session, abort the session.
462 The silc_client_abort_key_agreement now calls the completion
463 callback with new SILC_KEY_AGREEMENT_ABORTED status.
465 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
468 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
470 * Don't use __restrict in older GCC's. Affected file is
471 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
473 * silc_net_localhost now attempts to reverse lookup the
474 IP/hostname. Affected file lib/silcutil/silcnet.c.
476 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
477 command. It can be used to gain founder privileges at
478 the same time when joining the channel.
480 Defined that the SILC_NOTIFY_TYPE_KICKED send the
481 kicker's client ID as well. Updated protocol specs.
483 Defined that the server must send SILC_COMMAND_IDENTIFY
484 command reply with error status to client who sent
485 private message with invalid client ID.
487 Updated the protocol specification.
489 * Added silc_server_send_command_reply to send any
490 command reply. Affected file silcd/packet_send.[ch].
492 * Added silc_id_payload_encode_data to encode ID payload
493 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
495 * The server now send IDENTIFY command reply with error
496 status if client ID in private message is invalid. Affected
497 file silcd/packet_receive.c.
499 * Save the server key file with server's IP address in
500 the filename instead of hostname. The affected file is
501 irssi/src/silc/core/client_ops.c.
503 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
505 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
508 * Added libtool support for compiling shared objects in
509 lib/silcsim. Affected file configure.in.pre and
510 lib/silcsim/Makefile.am. Original patch by cras.
512 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
514 * Pid file configuration, and server's config file fixes
515 patch by toma. Updated CREDITS file.
517 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
519 * Fixed silc_client_channel_message to not try to decrypt
520 the message twice if it resolved the destination client
521 information. This could cause of dropping one channel
522 message. Affected file lib/silcclient/client_channel.c.
524 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
526 * Added silc_client_run_one into lib/silcclient/silcapi.h and
527 lib/silcclient/client.c. This function is used when the SILC
528 Client is run under some other scheduler, or event loop or
529 main loop. On GUI applications, for example this may be
530 desired to used to run the client under the GUI application's
531 main loop. Typically the GUI application would register an
532 idle task that calls this function multiple times in a second
533 to quickly process the SILC specific data.
535 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
537 * Fixed silc_server_drop() for dropping the supplementary
538 groups as well, this could cause a security hole on some
541 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
543 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
546 * Write PID file after dropping privileges. Added -F option
547 to run server on foreground. A patch by debolaz.
548 Affected files silcd/server.c, silcd/silcd.c.
550 * Fixed MOTD to return the MOTD file server name. Affected
551 file silcd/command.c.
553 * Added INFO command reply handling to the Irssi SILC Client.
554 Affected file irssi/src/silc/core/client_ops.c.
556 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
558 * Fixed the silc_idcache_list_* routines to really support
559 the dynamic list. Fixes a crash. Affected file is
560 lib/silccore/silcidcache.c.
562 * Fixed the LIST command reply to really call LIST command's
563 pending callbacks. Affected file silcd/command_reply.c.
565 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
567 * Update conn->local_entry->nickname after giving NICK
568 command. Affected file lib/silcclient/command.c.
570 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
572 * Added the [pid] option to the silcd configuration file
574 Affected files: serverconfig.[ch] and silcd.c
576 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
578 * Save fingerprint in WHOIS command reply in server.
579 Affected file silcd/command_reply.c.
581 * Fixed NICK commands pending callback registration.
582 Affected file lib/silcclient/command.c.
584 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
586 * Use ++server->cmd_ident when sending commands in server,
587 instead of random number. Affected file silcd/command.c.
589 * Fixed GETKEY command reply to call actually GETKEY pending
590 command callbacks. Affected file silcd/command_reply.c.
592 * A bit stricter check for nicknames. Check for same nickname
593 in NICK command also. Affected file silcd/command.c.
595 * Do not call INFO command everytime client ID changes, only
596 during first connecting. Affected file lib/silcclient/client.c.
598 * Set the new nickname only after successful command reply for
599 NICK command is returned by server. Affected file
600 lib/silcclient/command.c.
602 * Remove nicknames from nicklist during server_signoff notify.
603 Should fix /NAMES bit more. The affected file is
604 irssi/src/silc/core/silc-channels.c.
606 * Added `fingerprint' field to the SilcIDListData in the
607 silcd/idlist.h to hold the fingerprint of the client's
610 Send the fingerprint of the client's public key in WHOIS
613 Affected files silcd/command.c, and silcd/idlist.[ch].
615 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
616 create fingerprint from given data.
618 * Show the fingerprint of the client's public key in WHOIS.
619 Affected files irssi/src/module-formats.[ch] and
620 irssi/src/silc/core/client_ops.c.
622 * Format the multiple same nicknames also during JOIN and
623 NICK_CHANGE notifys. Affected file is
624 lib/silcclient/client_notify.c.
626 * Do not print error on screen for invalid private message
627 payload since it can come if someone is sending private
628 messages with wrong key. Affected file
629 lib/silccore/silcprivate.c.
631 * Fixed multiple concurrent /PING crash. Affected file
632 lib/silcclient/command.c.
634 * Changed the wrong ID encoding. All IP addresses must be
635 in MSB first order in encoded format. They were encoded
636 wrong and was in LSB format. Affected files are
637 silcd/serverid.c, lib/silcutil/silcutil.c.
639 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
641 * Call the `connect' client operation through the scheduler
642 in case of error. Affected file lib/silcclient/client.c.
644 * Call the `failure' client operation even if the error
645 occurred locally during a protocol. Affected file is
646 lib/silcclient/protocol.c.
648 * Added support of sending LIST command to router from normal
649 server. This way normal server can get list of all channels
650 in the network too. Fixed the channel list sending in the
651 server too. Affected files are silcd/command.c, and
652 silcd/command_reply.[ch].
654 * Added silc_server_update_channels_by_server and
655 silc_server_remove_channels_by_server. They are used during
656 disconnection of primary router and in backup router protocol.
657 Affected file silcd/server_util.[ch], silcd/server.c and
658 silcd/server_backup.c.
660 * Fixed channel adding to global list in IDENTIFY command
661 reply in server. Affected file silcd/command_reply.c.
663 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
665 * If the incoming packet type is REKEY or REKEY_DONE process
666 that packet always synchronously. Fixes yet another MAC
667 failed error on slow (dialup) connections. Affected file
668 lib/silcclient/client.c and silcd/server.c.
670 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
672 * Call check_version SKE callback for initiator too. Affected
673 file lib/silcske/silcske.c.
675 * Implemented fix for security hole found in the SKE that was
676 fixed in the specification few days back; the initiator's
677 public key is now added to the HASH value computation.
678 Added backwards support for the old way of doing it too, for
679 old clients and old servers. Affected file is
680 lib/silcske/silcske.c.
682 * Enabled mutual authentication by default in SKE. If initiator
683 is not providing mutual authentication the responder will
684 force it. This will provide the proof of posession of the
685 private key for responder. The affected files are
686 lib/silcclient/protocol.c and silcd/protocol.c.
688 * Do not cache anymore the server's public key during SKE.
689 We do mutual authentication so the proof of posession of
690 private key is done, and if the server is authenticated in
691 conn auth protocol with public key we must have the public
692 key already. Affected file silcd/protocol.c.
694 * Added new global debug variable: silc_debug_hexdump. If
695 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
696 file lib/silcutil/silclog.[ch].
698 * Fixed compilation warning due to char * -> const char *.
699 Affected files lib/silcutil/silcnet.h, and
700 lib/silccore/silcauth.[ch].
702 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Fixed CMODE command when new channel key was created. If
705 the creation failed the old key was removed. Next time giving
706 same command would crash the server since the old key was
707 freed already. Affected file silcd/command.c.
709 * Fixed the silc_server_announce_get_channels to not crash
710 on reconnect. Affected file silcd/server.c.
712 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
714 * Added silc_log_set_debug_string function to set a regex
715 string to match for debug output. Only the function names,
716 or filenames matching the given debug string is actually
717 printed. This way it is possible to filter out those debug
718 strings that user is not interested in.
720 Fixed a bug in silc_string_regexify.
722 Affected files lib/silcutil/silclog.[ch], and
723 lib/silcutil/unix/silcunixutil.c.
725 * Changed the -d options in both server and Irssi SILC client
726 to take the debug string as argument. Affected files
727 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
729 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
731 * Added silc_hash_babbleprint to create a Bubble Babble
732 Encoded fingerprint. The encoding is developed by Antti
733 Huima (draft-huima-babble-01.txt), and it creates human
734 readable strings out of binary data. Affected file
735 lib/silccrypt/silchash.[ch].
737 * Print the babble print now in addition of fingerprint as well
738 in Irssi SILC client. Affected files are
739 irssi/src/fe-common/silc/module-formats.[ch],
740 irssi/src/fe-common/silc/core/client_ops.c.
742 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
744 * Fixed a security problem found in SKE. The initiator's
745 public key too is now added to the HASH hash value creation
746 which is signed by the responder to create the SIGN value.
747 This will prevent anyone in the middle to lie to the responder
748 about the initiator's public key. If this is done now, the
749 man in the middle will get caught. Updated the protocol
752 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
754 * Better installation directory handling. Configure module
755 paths and other paths automatically to example_silc* files
756 in doc/. A patch by toma.
758 * Fixed compiler warning from MPI library, and from SILC RNG.
761 * Added SILC_SERVER_PID_FILE to define the pid file for server.
762 It can be configured with ./configure. A patch by toma.
764 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
766 * Find correct make to use in prepare-clean. A patch by
767 toma. Affected file prepare-clean.
769 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
771 * Added irssi variables use_auto_addr, auto_bind_ip,
772 auto_bind_port and auto_public_ip.
774 * Changed the interface for silc_client_send_key_agreement
775 in lib/silcclient/silcapi.h
779 irssi/src/silc/core/silc-core.c
781 lib/silcclient/silcapi.h
782 irssi/src/silc/core/silc-channels.c
783 lib/silcclient/client_keyagr.c
786 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
788 * Added silc_pkcs_public_key_compare to compare two
789 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
791 * Check that the client who set the founder mode on the
792 channel is the same client that is giving the founder
793 mode to itself. It is done by comparing the saved public
794 key (it is saved even in the authentication is passphrase).
795 Affected file silcd/command.c.
797 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
799 * Do not process packet for disconnected socket connection.
800 Affected file lib/silccore/silcpacket.c.
802 * Process the DISCONNECT packet through scheduler in the
803 client library. Affected file lib/silcclient/client.c.
805 * Fixed the silc_client_packet_parse to not to increase
806 the packet sequence number if the conn->sock and the
807 current socket connection is not same. This can happen
808 for example during key agreement when the conn includes
809 multiple socket connections (listeners). Affected file
810 lib/silcclient/client.c.
812 * The sender of the file transfer request now provides also
813 the pointer (listener) for the key exchange protocol. If
814 the listener cannot be created then it sends empty key
815 agreement and lets the receiver provide the listener.
817 Added `local_ip' and `local_port' arguments to the
818 silc_client_file_send. If they are provided they are used,
819 if not then it will attempt to find local IP address, if
820 not found or bind fails then the remote client will provide
823 Affected files are lib/silcclient/client_ftp.c and
824 lib/silcclient/silcapi.h.
826 * Extended the FILE SEND command to support defining the
827 local IP and port for key exchange listener. They are
828 optional. Affected file irssi/src/silc/core/silc-servers.c.
830 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
832 * Defined to WHOIS command reply the sending of fingerprint
833 of the client's public key (if the proof of posession of the
834 corresponding private key is verified by the server).
835 Updated to the protocol specification.
837 * Added support of receiving the client's public key's
838 fingerprint in command reply in client library. Affected
839 file is lib/silcclient/command_reply.c, and
840 lib/silcclient/idlist.[ch].
842 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
844 * Do not send over 128 chars long nickname to the server
845 in NICK command. Affected file lib/silcclient/command.c.

848 in JOIN command. Affected file lib/silcclient/command.c.
850 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
852 * Assure that silc_server_close_connection cannot be called
853 twice for same socket context. Affected file is
856 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
858 * Send error message to application if opening file for
859 writing during file transfer fails. Affected file is
860 lib/silcclient/client_ftp.c.
862 Remove all file transfer sessions for a client that we're
863 removing from ID cache.
865 Affected file is lib/silcclient/client_ftp.c.
867 * Fixed silc_net_addr2bin to return correct address. Affected
868 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
870 * Fixed file transfer session removing on signoff notify.
871 Affected file irssi/src/silc/core/silc-servers.c.
873 * Added the SilcClientFileError to be returned in the monitor
874 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
875 Affected file lib/silcclient/silcapi.h.
877 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
879 * Fixed a crash in silc_client_ftp_free_sessions and
880 silc_client_ftp_session_free_client. Affected file
881 lib/silcclient/client_ftp.c.
883 * Added `disabled' field in the SilcChannelEntry in the server
884 to indicate if the server entry is disabled. Affected file
885 silcd/idlist.h, silcd/command[_reply].c.
887 * SILC server adds now /var/run/silcd.pid everytime it is
888 started. Affected file silcd/silcd.c.
890 * Added silc_server_packet_send_clients to send a packet to
891 the provided table of client entries. Affected file
892 silcd/packet_send.[ch].
894 * Fixed a crash in client resolving in client_prvmsg.c in
895 client library. Affected file lib/silcclient/client_prvmsg.c.
897 * Do not actually remove the client directly from ID cache
898 during SERVER_SIGNOFF, but invalidate it. This way we
899 preserve the WHOWAS info for the client. Affected file
902 * Fixed SERVER_SIGNOFF notify handling in the server. The
903 server is now able to process incoming SERVER_SIGNOFF notify
904 for a server that it doesn't even know about. It will remove
905 the clients provided in the notify. Affected file
906 silcd/packet_receive.c.
908 * Check for partial packet in data queue after every packet that
909 was found from the queue. Return and wait for more data if
910 there is partial data in queue. Affected file is
911 lib/silccore/silcpacket.c.
913 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
915 * Added SilcClietFileError enum to indicate error in
916 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
917 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
918 Affected files lib/silcclient/silcapi.h and
919 lib/silcclient/client_ftp.c.
921 * Check that newsize in silc_buffer_realloc is larger than
922 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
924 * Added better monitor of file transfers. It now monitors
925 key agreement protocol during the file transfer too. Added
926 error reporting too. Affected files
927 irssi/src/silc/core/silc-servers.c,
928 irssi/src/fe-common/silc/module-formats.[ch].
930 * Wrote a help file for FILE command.
932 * Added silc_rng_global_get_byte_fast to get not-so-secure
933 random data as fast as possible. Random data is read from
934 /dev/urandom if available and from the SILC RNG if not
935 available. It is used in padding generation. Affected file
936 lib/silccrypt/silcrng.[ch].
938 * All packets in client library are now processed synchronously.
939 Optimized packet processing a lot. Affected file
940 lib/silcclient/client.c.
942 * All server connection packets are processing synchronously
943 now in server, to optimize packet processing. Affected file
946 * Include files are installed now only in Toolkit distribution
947 if make install is given. Affected files: all Makefile.am's.
949 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
951 * Assure that silc_client_notify_by_server_resolve does not
952 resolve the client information multiple times. If it cannot
953 be found by the first it cannot be found at all. Affected
954 file lib/silcclient/client_notify.c.
956 * Fixed WHOWAS command reply calling. Affected file
957 lib/silcclient/command_reply.c.
959 * Removed all references to silc_idlist_get_client from the
960 Irssi SILC client since that call is internal call used by
961 the library. The Irssi SILC client will use now client
962 retrieval functions found in silcapi.h.
964 * Fixed a bug in resolving nickname info before sending
965 private message. It used freed memory. Affected file
966 irssi/src/silc/core/silc-servers.c.
968 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
970 * Assure my_channels statistics cannot go negative in server.
971 Affected files silcd/server.c, silcd/server_util.c.
973 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

983 lib/sftp/sftp_fs_memory.c.
985 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
987 * Added silc_net_localip to return local host's IP address.
988 Affected file lib/silcutil/silcnet.[ch].
990 * If key exchange or rekey protocol is active for a connection
991 parse all packets syncronously since there might be packets
992 in packet queue that we are not able to process without first
993 processing packets before them. Affected file silcd/server,
994 lib/silcclient/client.c.
996 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
997 whether library should continue processing the packet.
998 Affected file lib/silccore/silcpacket.h.
1000 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1001 SilcSFTPMonitorData to SFTP server to monitor various

1010 transmission. Affected file lib/silcclient/client_ftp.c,
1011 lib/silccilent/client.[ch].
1013 * Added new local command FILE to the Irssi SILC Client.
1014 It is used to perform the file transfer. It has subcommands
1015 SEND, RECEIVE, SHOW and CLOSE. Affected files
1016 irssi/src/silc/core/client_ops.c,
1017 irssi/src/silc/core/silc-server.[ch].
1019 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1021 * Relay the SILC_PACKET_FTP in the server. Affected files
1022 silcd/server.c and silcd/packet_receive.c.
1024 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1026 * Renamed silc_file_read and silc_file_write to functions
1027 silc_file_readfile and silc_file_writefile. Added function

1029 lib/silcutil/silcutil.[ch].
1031 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1033 * Resolve the client info when received private message or
1034 channel message for a client which nickname we don't know.
1035 Affected files lib/silcclient/client_prvmsg.c and
1036 lib/silcclient/client_channel.c.
1038 * Do not crash in /KEY if client is not connected. Affected
1039 file irssi/src/silc/core/silc-channels.c.
1041 * Added SilcClientStatus field to the SilcClientEntry in the
1042 lib/silcclient/idlist.h.
1044 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1045 is incomplete and is being resolved, it won't be resolved
1048 Make sure also that USERS command reply does not resolve
1049 twice information. Affected file is
1050 lib/silcclient/command_reply.c.
1052 Make sure that silc_client_get_clients_by_list does not
1053 resolve twice same information.
1055 * Check for valid client->id in the silc_server_free_client_data.
1056 Affected file silcd/server.c.
1058 * Fixed /GETKEY nick@server not to crash if the server entry
1059 is not found. Affected file lib/silcclient/command.c.
1061 * Fixed the silc_server_check_cmode_rights to check the
1062 requested modes correctly. Affected file silcd/command.c.
1064 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1066 * Better checks for non-printable chars in nick added.
1067 Affected file silcd/command.c.
1069 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * Call the silc_server_udpate_servers_by_server in the
1072 primary router that comes back online in the backup resuming
1073 protocol. Otherwise it routes packets wrong. Affected file
1074 silcd/server_util.[ch], silcd/server_backup.c.
1076 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1078 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1079 lib/silcutil/silcbuffmt.[ch].
1081 * Redefined the SILC packet header to include the padding
1082 length. Affected file lib/silccore/silcpacket.[ch].
1084 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1085 length for maximum padding up to 128 bytes). Affected
1086 file lib/silccore/silcpacket.h.
1088 * Removed all backwards support for old 0.5.x MAC thingies.
1089 The SILC packet header change makes it impossible to be
1090 backwards compatible.
1092 * Send the ENDING packet with timeout in the backup resuming
1093 protocol. This is to assure that all routers has connected
1094 to the primary router. Affected file silcd/server_backup.c.
1096 * Changed the RNG to take the first IV from random data. It
1097 used to take it from zero actually. Changed the RNG also
1098 to use /dev/urandom during session. /dev/random is used
1099 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1101 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1103 * Changed the SILC packet header to have the first two bytes
1104 (the packet length) encrypted. Affected files aroung the
1105 code tree, lib/silccore/silcpacket.[ch]. Removed the
1106 SilcPacketCheckDecrypt callback. It is not needed anymore
1107 since the silc_packet_receive_process will determine now
1108 whether the packet is normal or special.
1110 * Implemented the unidirectional MAC keys. Affected files
1111 lib/silcske/silcske.c, silcd/protocol.c and
1112 lib/silcclient/protocol.c.
1114 * Implemented the packet sequence number to the MAC computation.
1115 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1116 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1117 lib/silcclient/protocol.c.
1119 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1121 * Allow backup router to announce servers. All servers
1122 announced by backup router are added to the global list
1123 automatically. Update hte server's socket to our primary
1124 router also when backup router announces a server.
1125 Affected file silcd/packet_receive.c.
1127 * Do not update the client->router in the function
1128 silc_server_udpate_clients_by_server if the client is on
1129 global list. We might fail to find any specific server
1130 for locally connected clients and local cell clients. They
1131 should still use the `from' and not `to' as client->router.
1132 This fixes backup router resuming protocol. Affected file
1133 silcd/server_util.c.
1135 * Decrease channel statistics count only if the channel
1136 deletion worked. Affected files are silcd/server.c and
1137 silcd/server_util.c.
1139 * Added silc_server_update_servers_by_server to update origin
1140 of all server entries. Used during backup router protocol.
1141 Affected files silcd/server_util.[ch], silcd/server.c. and
1142 silcd/backup_router.c.
1144 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1145 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1146 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1147 lib/silccrypt/silchmac.c.
1149 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1151 * Assure that router cannot reroute the same channel message
1152 to the sender. Affected file silcd/packet_receive.c.
1154 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1156 * Made better checks that the channel message is not sent
1157 to the router it came from. Affected file is
1158 silcd/packet_send.c. Fixed memory leak too.
1160 * Announce informations for incoming router connection, but
1161 only after checking if it is replaced by backup router.
1162 Affected file silcd/packet_receive.c.
1164 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1166 * Fixed the backup resuming protocol to work in multiple
1167 router environment. Affected file silcd/server_backup.c.
1169 * Route packet only to one router in the function
1170 silc_server_packet_send_to_channel. Affected file is
1171 silcd/packet_send.c.
1173 * Fixed silc_server_send_notify_dest to set the broadcast
1174 flag. Fixed the silc_server_send_notify_topic to actually
1175 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1176 Affected file silcd/packet_send.c.
1178 * Changed the SFTP Filesystem interface. Changed the
1179 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1180 the filesystem operation function. The SilcSFTPFilesystem
1181 is now a context that is allocated by all filesystem allocation
1182 functions and it already includes the operations structure
1183 and filesystem specific context. It is given as argument
1184 now to the silc_sftp_server_start. This made the interface
1185 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1186 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1188 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1190 * Changed the backup router adding and getting interfaces
1191 in the server. The router that will be replaced by the
1192 specified backup router is now sent as argument. Affected
1193 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1196 * Added silc_net_addr2bin_ne to return the binary form of
1197 the IP address in network byte order. Affected files
1198 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1200 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1202 * Check for existing server ID in silc_server_new_server
1203 and in silc_server_connect_to_router_final and remove the
1204 old entry if it exists. Affected file silcd/packet_receive.c,
1207 * Send the channel message always to only one router, either
1208 in upstream or downstream. Affected file is
1209 silcd/packet_send.c.
1211 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1213 * Wrote the definition of the backup resuming protocol to the
1214 protocol specification.
1216 * Removed one redundant channel key generation from normal
1217 server during joining procedure. Removed one redundant
1218 channel key sending from server to router during joining
1219 procedure. Affected file silcd/command.c.
1221 * Made minor bugfixes to the backup router resuming protocol.
1222 Affected file silcd/server_backup.c, server.c.
1224 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1226 * Added --disable-asm configuration option. Affected files
1227 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1230 * Implemented the backup resuming protocol that is used to
1231 resume the primary router position in the cell after the
1232 primary router comes back online. Affected files
1233 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1234 and silcd/server_util.[ch].
1236 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1238 * Sleep two (2) seconds after sending QUIT command to server.
1239 Affected file lib/silcclient/command.c.
1241 * Assure that if outgoing data buffer is pending do not force
1242 send any data. Affected file silcd/packet_send.c.
1244 * Assure that if outgoing data buffer is pending do not force
1245 send any data. Affected file lib/silcclient/client.c.
1247 * Implemented the backup router support when the primary router
1248 goes down. The servers and routers can now use the backup
1249 router as new primary router without loosing connectivity.
1251 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1254 in the server to indicate disabled entry. All data read
1255 from the connection will be ignored and no data is sent
1256 for entry that is disabled. Affected files are
1257 silcd/idlist.h, silcd/server.c.
1259 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1261 * Created SFTP client and server test programs in the
1262 lib/silcsftp/tests directory.
1264 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Implemented memory filesystem (virtual filesystem) for
1267 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1270 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Implemented the SFTP (SSH File Transfer Protocol) to the
1273 lib/silcsftp. It includes SFTP client and SFTP server
1276 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1278 * Moved lib/silccore/silcprotocol.[ch] to the
1279 lib/silcutil library.
1281 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1282 take variable argument list pointer as argument. Affected
1283 file lib/silcutil/silcbuffmt.[ch].
1285 * Added silc_buffer_set function that is used to set data
1286 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1287 Affected file lib/silcutil/silcbuffer.h.
1289 * Changed various routines in the core library to use the new
1290 silc_buffer_set instead of allocating new buffer only for
1293 * Added 64-bit value formatting and unformatting support to the
1294 silc_buffer_[un]format routines. Affected file is
1295 lib/silcutil/silcbuffmt.[ch].
1297 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1298 to includes/bitmove.h.
1300 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1302 * Fixed channel user mode saving in client library. Affected
1303 file lib/silcclient/command[_reply].c.
1305 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1307 * Defined the file transfer to the SILC Protocol. Added
1308 new packet type SILC_PACKET_FTP and defined File Transfer
1309 Payload. The mandatory file transfer protocol is SFTP
1310 (SSH File Transfer Protocol). Affected file in addition
1311 of the internet draft is lib/silccore/silcpacket.h.
1313 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1314 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1315 is used as part of backup router protocol when the primary
1316 router of the cell is back online and wishes to resume
1317 the position as primary router.
1319 * Redefined the MAC generation keys in the protocol. The
1320 same key is not used anymore in both direction. Both
1321 direction will now use different keys for sending and
1322 receiving. This fixes a potential security flaw. This
1323 change causes incompatibilities in the protocol.
1325 * Redefined also the MAC computation from the packet.
1326 An packet sequence number is now added to the MAC
1327 computation. This prevents possible replay attacks against
1328 the protocol. This change too causes incompatibilities
1331 Added `sequence' field to the SilcPacketContext to hold
1332 the current sequence number for the packet.
1334 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1336 * Added `created' field to the SilcIDListData in the file
1337 silcd/idlist.h to indicate the time when the entry was
1340 * Added `created' field to the SilcChannelEntry too. Affected
1341 file silcd/idlist.h.
1343 * Added `creation_time' aguments to all the announcement functions
1344 in the server. If it is provided then only the entries that
1345 was created after the provided time frame are actually
1346 announced. Affected file silcd/server.[ch].
1348 * The protocol says that the Channel ID's IP address must be
1349 based on the router's IP address. Added check for this in
1350 the silc_server_new_channel when processing incoming New Channel
1351 Payload. Affected file silcd/packet_receive.c.
1353 * Print out the correct version with --version in SILC client.
1354 Affected file irssi/src/silc/core/silc-core.c.
1356 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Fixed WHOWAS command to check for completnes of the client
1359 entry always, not just when the command is coming from client.
1360 Affected file silcd/command.c.
1362 * Added new function silc_server_packet_queue_purge to purge the
1363 outgoing data queue to the network. After the function returns
1364 it is guaranteed that the outgoing packet queue is empty.
1365 Affected file silcd/packet_send.[ch].
1367 * Purge the outgoing packet queue in the rekey protocol's final
1368 callback to assure that all rekey packets go to the network
1369 before quitting the protocol. Affected file silcd/server.c.
1371 * Added silc_client_packet_queue_parse as similar function as
1372 in server to the client library. The affected file is
1373 lib/silcclient/client.c.
1375 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1377 * Splitted silcd/server.c and created silcd/server_util.[ch]
1378 for utility functions.
1380 * Added new socket flag SILC_SF_DISABLED to indicate that the
1381 connection is open but nothing can be sent to or received from
1382 the connection. Affected file lib/silcutil/silsockconn.[ch].
1383 The checking for disabled socket is checked in the low level
1384 silc_socket_write and silc_socket_read functions.
1386 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1388 * Allow only nicknames and channel names that fits into the
1389 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1391 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * When processing JOIN command reply in server check that if
1394 the channel exists in our global list we'll move it the local
1395 list. Affected file silcd/command_reply.c.
1397 * Fixed the check whether client is joined on the channel already
1398 in JOIN command. Affected file lib/silcclient/command.c.
1400 * Fixed the JOIN command reply to check whether the channel
1401 already exists. Affected file lib/silcclient/command_reply.c.
1403 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * Added silc_ske_status_string to map the SKE error numbers
1406 to readable strings. The affected files are
1407 lib/silcske/silcske[_status].[ch].
1409 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Do not show the private channels on the WHOIS channel list
1412 as it is not allowed by the protocol. The affected file is
1415 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Assure that the packet length digged from the actual packet
1418 is something sensible in the silc_packet_decrypt_rest_special
1419 in lib/silccrypt/silcpacket.c.
1421 * Free and NULL the allocated pointer in silc_hmac_alloc if
1422 the HMAC allocation fails. The affected file is
1423 lib/silccrypt/silchmac.c.
1425 * Print the selected security properties to the log files in
1426 the server. Affected file silcd/protocol.c.
1428 * Add SKE's reference counter even if calling the completion
1429 callback manually. Otherwise it goes negative, although it
1430 does not cause any problems. The affected file is
1431 lib/silcske/silcske.c.
1433 * Remove the client entry with short timeout after giving the
1434 KILL command. Affected file lib/silcclient/command.c.
1436 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1437 case all found clients are already disconnected (WHOWAS would
1438 found them) in the server. Affected file silcd/command.c.
1440 * Update the last_receive (time of last data received) to be
1441 updated only when received private or channel message so that
1442 the idle time showed in WHOIS makes more sense.
1444 * Added boolean field `valid' in to the SilcClientEntry in the
1445 client library to indicate whether the entry is valid or not.
1446 This fixes the nickname change bug on channel when changing
1447 the nickname to be same than the old (like nick to Nick) the
1448 nickname formatter doesn't set the new nick anymore to Nick@host.
1449 Affected file lib/silcclient/idlist.[ch].
1451 * Now actually fixed the nickname changing on disconnection.
1452 Added new function silc_change_nick to the Irssi SILC Client.
1453 Affected file irssi/src/silc/core/client_ops.c,
1454 irssi/src/silc/core/silc-nicklist.[ch].
1456 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Check that the public key exists in the GETKEY command before
1459 trying to encode it. Affected file silcd/command.c.
1461 * Print some notifications on received public keys with GETKEY
1462 command in the Irssi SILC Client. Affected files are
1463 irssi/src/fe-common/silc/module-formats.[ch],
1464 irssi/src/silc/core/client_ops.c.
1466 * Use IDENTIFY command to resolve the server information in the
1467 GETKEY command instead of INFO command. Affected file
1468 lib/silcclient/command.c.
1470 * All command reply functions in the client library now calls
1471 the pending command reply callbacks even if an error has
1472 occurred. The server has done this a long time and now it was
1473 time to move the client library to this as well. Now all
1474 errors can be delivered back to the pending command reply
1475 callbacks if necessary. Affected files are
1476 lib/silcclient/command[_reply].[ch].
1478 * Change the nickname on disconnection back to the username
1479 because in reconnect the server will enforce it to it anyway.
1480 Affected file irssi/src/silc/core/silc-servers.c.
1482 * Fixed a config file parsing bug in the Irssi SILC client.
1483 Affected file irssi/src/silc/core/clientconfig.c.
1485 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1487 * When printing the channel mode on JOIN, verify that the
1488 channel key and channel's HMAC are valid. Affected file
1489 irssi/src/silc/core/client_ops.c.
1491 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1494 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1495 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1497 * Removed channel key rekey task deleting from the function
1498 silc_server_save_channel_key. Affected file silcd/server.c.
1499 Added explicit timeout task context instead that is used to
1500 delete the task if we are registering a new task before the
1501 new task has elapsed.
1503 * When channel key rekey occurs the client library now saves
1504 the old channel key for a short period of time (10 seconds) and
1505 is able to use it in case some is still sending channel
1506 messages encrypted with the old key after the rekey. Affected
1507 file lib/silcclient/[idlist.h|client_channel.c].
1509 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1511 * Added check to the silc_server_new_id_real to not accept
1512 new ID if it is the sender's own ID. Affected file is
1513 silcd/packet_receive.c.
1515 * Assure that we do not announce ourself or the one we've
1516 sending our announcements when we're router and are announcing
1517 servers to our primary router. Affected file silcd/server.c.
1519 * Fixed silc_server_command_identify_check_client to assemble
1520 correct WHOIS packet. It send corrupted WHOIS packet and
1521 caused problem with router to router connections. Affected
1522 file silcd/command.c.
1524 Fixed also silc_server_command_whois_check the same way
1525 as for the IDENTIFY command.
1527 * Added new SilcIDListStatus to the server in the SilcIDListData
1528 structure. The status now includes the current status of
1529 the entry (like registered, resolved etc.). Affected file
1530 silcd/idlist.[ch]. Defined a bunch of different status types
1531 as well. This replaced the old boolean registered field as well.
1533 Added resolve_cmd_ident field to the SilcClientEntry structure
1534 too so that if the entry is for example being resolved so
1535 another command may attach to the same pending command reply
1536 without requiring to resolve the same entry again. This concept
1537 should optimize the WHOIS and the IDENTIFY resolving under
1538 heavy load by taking away unnecessary resolving for entries
1539 that are being resolved already.
1541 Added support for adding multiple pending commands for one
1542 command idenfier. Affected file silcd/command[_reply].[ch].
1544 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1545 before deleting the data. Otherwise the hash table will have
1546 freed data in comparison functions. Affected file is
1547 silcd/command_reply.c.
1549 * Fixed silc_idlist_replace_client_id to add the new entry to
1550 the cache with NULL nickname. Otherwise there will be invalid
1551 memory as the nickname after the nickname is freed. Affected
1552 file silcd/packet_receive.c.
1554 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1555 saved into wrong slots because the previous number of entries
1556 was not taken into account. Affected file silcd/idlist.c.
1557 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1559 * If we are router and we receive JOIN notify to a channel that
1560 does not have any users then notified client is marked as the
1561 channel founder, as it is it. The affected file is
1562 silcd/packet_receive.c
1564 * Added to the extended hash table API's table_del_*ext functions
1565 the destructor as argument too, so that the caller can decide
1566 which destructor to use or whether to use destructor at all.
1567 Affected file lib/silcutil/silchashtable.[ch].
1569 * Fixed ID Cache purging. It actually deleted the entries from
1570 the hash table after the data was freed. The hash table ended
1571 up comparing freed memory. The affected file is
1572 lib/silccore/silcidcache.c.
1574 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1576 * Fixed Irssi SILC client's KILL command's HELP syntax.
1578 * The USERS command now resolves the detailed user information
1579 if the userinfo field is missing. Affected file is
1580 lib/silcclient/command_reply.c.
1582 * Do not print error in silc_file_read if the read file does
1583 not exist. Just silently return NULL. Affected file is
1584 lib/silcutil/silcutil.c.
1586 * Fixed the silc_log_output to not wine about NULL filename
1587 and to not create some bogus " " filename. Affected file is
1588 lib/silcutil/silclog.c.
1590 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1592 * Fixed various printing bugs on the user interface in the
1593 Irssi SILC Client. Minor changes that were forgotten from
1596 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Fixed the configure.in.pre and the compilation and distribution
1599 environment to support the new autoconf 2.52. That version is
1600 now required to compile the CVS trunk.
1602 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1604 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1605 to generally parse user@fqdn format strings. Affected file
1606 lib/silcutil/silcutil.c.
1608 * Added nickname_format and nickname_force_format fields to the
1609 SilcClientParams structure. The first one defines the format
1610 for the nicknames that the library will enforce if the receives
1611 multiple same nicknames. The second one is boolean value and
1612 can be used to force the library to always enforce the format
1613 to the nicknames regardles whether there are multiple nicknames
1614 or not. This configurable formatting was employed to flexibly
1615 support accessing multiple nicknames from the user interface.
1616 The userinterface can now set the nicknames to what ever format
1617 they prefer. Affected file lib/silcclient/silcapi.h.
1619 Added function silc_client_nickname_format to the file
1620 lib/silcclient/idlist.c. It performs the nickname formatting.
1622 Added new field `hostname´ to the SilcClientEntry context.
1623 It holds the hostname of the client. Affected file is
1624 lib/silcclient/idlist.h.
1626 * Irssi SILC Client sets the nicknames in nick@hostn format.
1627 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1628 irssi/src/silc/core/silc-core.c.
1630 The WHOIS printing now also shows both the real nickname and
1631 the formatted nickname so that user knows how to access the
1632 user if there are multiple same nicknames cached. Affected
1633 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1634 printing formatting too to take the hostname now as a separate
1635 argument. The Affected file is
1636 irssi/src/fe-common/silc/modules-formats.[ch].
1638 * Changed the silc_client_get_clients_local to accept the formatted
1639 nickname as argument. It accepts the real nickname too but the
1640 formatted nickname can be used to find the true entry from
1641 multiple entries. Affected file lib/silcclient/silcapi.h and
1642 lib/silcclient/idlist.c.
1644 * Added nickname_format_parse field to the SilcClientParams.
1645 It is a callback function provided by the application to parse
1646 the nickname out of the formatted nickname string. The library
1647 calls it to get the nickname from the formatted string. Since
1648 the application generally knows better the format of the nickname
1649 string it parses it instead of the library, even though library
1650 encodes the formatted string. If the callback function is not
1651 provided then the library will use the string as is. The
1652 affected file is lib/silcclient/silcapi.h.
1654 * All the nickname strings passed to the client library in
1655 commands are now expected to be formatted nickname strings.
1656 If the command does not support the formatted nickname string
1657 it will assume that the sent string is the actual nickname.
1658 Affected file lib/silcclient/command.c.
1660 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1662 * Added public key authentication support to OPER and SILCOPER
1663 commands in the client library. Affected file is
1664 lib/silcclient/command.c.
1666 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Changed the get_auth_methdod client operation to be asynchronous.
1669 It can be async if the application resolves the authentication
1670 method from the server during the negotiation. Added new
1671 SilcGetAuthMeth completion callback that the application will
1672 call after resolving the authentication method.
1674 Added function silc_client_request_authentication_method that
1675 the application can use to resolve the authentication method
1676 from the server. Added also SilcConnectionAuthRequest callback
1677 that the library will call after the server has replied. The
1678 application can call this function if it does not know the
1679 current authentication method.
1681 Affected files are lib/silcclient/client.c and
1682 lib/silcclient/silcapi.h.
1684 * The Irssi SILC client now automatically resolves the authentication
1685 method incase any configuration information is not present (and
1686 currently there never is). The affected file is
1687 irssi/src/silc/core/client_ops.c.
1689 * Fixed public key authentication from the client library.
1690 Affected file lib/silcclient/protocol.c. Changed also the
1691 protocol specification about the public key authentication in
1692 the connection authentication protocol. The actual data to be
1693 signed is now computed with a hash function before signing.
1695 * Fixed the public key authentication from the server as well.
1696 Affected file silcd/protocol.c.
1698 * Removed the mlock()'s from the memory allocation routines.
1699 Affected file lib/silcutil/silcmemory.c. The ./configure does
1700 not check anymore for the mlock(). Affected file is
1703 * Fixed USERS command in server to allow the execution of the
1704 command for private and secret channels if the client sending
1705 the command is on the channel. Affected file silcd/command.c.
1707 * Fixed silc_client_get_clients_local to return the clients
1708 count correctly. It could return wrong value. Affected file
1709 lib/silcclient/idlist.c.
1711 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1713 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1714 types. The assembler optimizations seemed not to like 64-bit
1715 data types. The assmebler optimizations thus are now enabled
1716 also for BSD systems as opposed to only enable them for Linux.
1718 * Do not check for threads at all on BSD systems. Affected
1719 file configure.in.pre.
1721 * Removed -n and -h options from the Irssi SILC Client since
1722 they are not used in silc.
1724 * Fixed the prime generation to assure that the first digit
1725 of the generated random number is not zero since our conversion
1726 routines does not like number strings that starts with zero
1727 digit. If zero digit is seen the random number is regenerated.
1728 This caused some corrupted RSA keys when the zero first digit
1729 was met. Affected file lib/silcmath/silcprimegen.c.
1731 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1733 * Fixed WIN32 configuration in the ./configure script.
1734 Fixed to include xti.h on environments that has it.
1735 Patches by Carsten Ilchmann and andrew.
1737 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * Changed the silc_id_create_client_id to be collision
1740 resistant. It is now assured that there cannot be created
1741 two same client ID's. I suspect that some weird bugs in
1742 the server were actually caused by duplicate Client IDs.
1743 Affected file silcd/serverid.[ch]. A router receiving
1744 new ID now also assures and informs the sending server
1745 if the ID caused collision.
1747 * Changed the silc_id_create_channel_id to also assure that
1748 there are no collisions.
1750 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1752 * Statement about ignoring the Mutual Authentication flag when
1753 performing rekey with PFS was a bit misleading. It is ignored
1754 if it was set in the initial negotiation, it cannot be even
1755 set in the rekey. Fixed in the ke-auth draft. Started the
1756 new versions of the protocol drafts in the doc/.
1758 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Fixed a bug in silc_client_command_identify_save when saving
1761 new channel information. The channel name was no duplicated
1762 and caused crash on exit. Affected file is
1763 lib/silcclient/command_reply.c.
1765 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1767 * Fixed the getkey command handling in the server. Send just
1768 empty OK reply to the sender if the key could not be fetched
1769 (but everything else was ok, like the key just was not available).
1770 Changed the public key parameter to optional in the protocol
1771 specs so that empty OK reply can be sent. Affected file
1774 Added a message to Irssi SILC client to tell to user if the
1775 server did not return a public key.
1777 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1779 * Fixed a channel key regeneration bug. It registered new
1780 timeout tasks exponentially until all system resources were
1781 used. Affected file silcd/server.c.
1783 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1785 * Added the SILC Document generator to the scripts/silcdoc.
1786 It can be used to generate the Toolkit Reference Manual out
1787 of the source tree. Internally it will also use the RoboDoc
1788 generator now imported in util/robodoc.
1790 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Added couple of return's in rekey protocol if error orccurred
1793 during the protocol. The execution must be terminated.
1794 Affected file silcd/protocol.c. Also, terminate the protocol
1795 always with timeout.
1797 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * The client's Client ID was created initally from the wrong
1800 nickname (it could have been in format nick@host) in the
1801 silc_server_new_client. Affected file silcd/packet_receive.c
1803 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * Added some SILC_LOG_ERROR's to various error conditions
1806 if client could not be added to ID cache. Affected files
1807 silcd/packet_receive.c and silcd/server.c.
1809 * When client's sock->user_data is freed, NULL also the
1810 client->router and client->connection pointers. Added check
1811 for these pointers being NULL to various places around the
1812 code. Affected file silcd/server.c.
1814 * Added client->data.registered == TRUE checks to various
1815 places around the code to assure that unregistered client's
1816 are not handled when it is not allowed. Affected file
1819 * Added `bool registered' fields to all
1820 silc_idlist_[server|client]_get_* routines to indicate whether
1821 the fetched client needs to be registered or not. Affected
1822 file silcd/idlist.[ch].
1824 * Add your own entry as registered to the ID cache in the
1825 server. Affected file server.c.
1827 * Fixed a bug in silc_server_new_server. The SilcServer was
1828 set as the new server's context instead of SilcServerEntry.
1829 This naturally caused some weird bugs.
1831 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Do not delete the channel rekey task when adding it
1834 for in silc_server_create_channel_key.
1836 * Changed the silc_server_create_channel_key to return
1837 TRUE or FALSE to indicate the success of the channel key
1840 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * Fixed MSVC++ project files and added missing files to
1843 Makefiles under win32/.
1845 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1847 * Do not add TCP_NODELAY flag if the operating system
1848 does not have it defined. Affected files are
1849 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1851 * Fixed buffer overflow from Irssi SILC Client. Affected
1852 file irssi/src/fe-common/core/themes.c.
1854 * Fixed double free in client library in the file
1855 lib/silcclient/client.c when disconnecting from server.
1857 * Applied double free patch from cras to Irssi SILC client.
1858 Affected files irssi/src/core/[modules/expandos].c
1860 * Fixed the disconnection handling to Irssi SILC Client.
1861 The application must call silc_client_close_connection
1862 in ops->connect client operation in case of failure of
1863 the connection. Affected file is
1864 irssi/src/silc/core/client_ops.c.
1866 * Do not set sock->protocol to NULL in the function
1867 silc_client_close_connection after executing the protocol's
1868 final callback since the sock might not be valid anymore.
1869 Affected file lib/silcclient/client.c.
1871 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1873 * Do not enable SILC_THREADS if the linking with libpthread
1874 did not happen. Affected file configure.in.pre.
1876 * Added notion to protocol specification that server must
1877 verify the sent authentication payload with CMODE when
1878 setting the channel founder key. Implemented it to the
1879 server. Affected file silcd/command.c.
1881 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * Added _EXTRA_DIST SILC distribution variable to the
1884 distributions file. It is used to conditionally add extra
1885 files or directories to the specific distribution. Affected
1886 files ./prepare, Makefile.am.pre and distributions.
1888 Removed the `_' from the start of the distribution names.
1891 * Added README.WIN32 for instructions to compile the Toolkit
1894 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1896 * Fixed a double free in disconnection in the server. Affected
1897 file is silcd/server.c.
1899 * Fixed the lib/silcske/groups.c to work now also with GMP
1900 MP library. The string conversion did not work when using
1901 specific base and the base is indicated in the string as well.
1903 * Created win32/ directory which now includes MSVC++ specific
1904 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1905 It will appear only in the toolkit distribution
1907 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1909 * Changed the key material distribution function in case when
1910 the hash output is too short. The data is now concatenated
1911 a bit differently than it used to. Made the change to the
1912 SKE protocol specification.
1914 * Added better GMP detection to configure.in.pre. A patch
1917 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1919 * Fixed a minor bug in SKE that might cause some problem on
1920 some platforms. Affected file lib/silcske/silcske.c.
1922 * Added the cookie checking for initiator in the SKE. It checks
1923 that the responder returns the sent cookie unmodified. The
1924 affected file is lib/silcske/silcske.c. Added new SKE
1925 error type INVALID_COOKIE that can be sent during the
1926 negotiation. Fixed some memory leaks as well.
1928 * Added the "invalid cookie" error message to Irssi SILC client's
1931 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Added `task_max' field to the SilcClientParams to indicate
1934 the maximum tasks the scheduler can handle. If set to zero,
1935 default values are used. Affected file lib/silcclient/silcapi.h.
1937 * Fixed memory leaks in silc_client_close_connection. Affected
1938 file lib/silcclient/client.c.
1940 * Added silc_client_del_client_entry to client library to free
1941 all memory of given client entry. Affected file is
1942 lib/silcclient/idlist.[ch].
1944 * Added new functions silc_client_del_channel and
1945 silc_client_del_server to delete channel and server entries.
1946 Affected file lib/silcclient/[silcapi.h/idlist.c].
1948 * Removed silc_client_del_client_by_id from silcapi.h.
1950 * Fixed the INFO command to return the server's own info
1951 correctly when querying by Server ID. Affected file is
1954 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * Removed the non-blocking settings in WIN32 code in the
1957 silc_sock_[read/write] and added SleepEx instead. Affected
1958 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1959 of input data is now checked with FIONREAD and ioctlsocket.
1961 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1963 * Call silc_schedule_task_del_by_context in the
1964 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1965 Affected file lib/silccore/silcprotocol.c.
1967 * Call silc_protocol_cancel for active protocols in the
1968 silc_server_close_connection if the funtion
1969 silc_server_free_sock_user_data has not been called.
1970 Affected file silcd/server.c.
1972 * Generic tasks cannot be deleted using the del_by_fd
1973 task deleting function since generic tasks does not match
1974 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1976 * Added a notion to SILCOPER help file that the SILCOPER works
1977 only on router server, not on normal server.
1979 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * Added for WIN32 support for the new scheduler as well.
1982 Affected file lib/silcutil/win32/silcwin32schedule.c.
1984 * Fixed the SHA1 implementation to work on various platforms.
1986 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1989 API. It is part of the scheduler now. Everything else is
1990 as previously but some functions has changed their names.
1991 Checkout the lib/silcutil/silcschedule.h for the interface.
1992 Updated all applications to use the new interface. Affected
1993 files are lib/silcutil/silcschedule.[ch].
1995 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Found a bug in the SKE implementation. The HASH value,
1998 specified by the protocol, was not computed correctly. The
1999 public key of the responder was not added to the computation
2000 even though it is mandatory. Affected file lib/silcske/silcske.c.
2001 This unfortunately causes incompatibilities with older
2002 clients and servers.
2004 * Added WIN32 specific network init and uninit functions:
2005 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2006 the Winsock2. Affected file lib/silcutil/silcnet.h and
2007 lib/silcutil/win32/silcwin32net.c.
2009 * Set the socket always to nonblocking mode on WIN32 after
2010 reading data or writing data. Affected file is
2011 lib/silcutil/win32/silcwin32sockconn.c.
2013 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2015 * Fixed various compilation problems under WIN32. Affected
2016 files lib/silcutil/win32/silcwin32thread.c and
2017 lib/silcutil/win32/silcwin32schedule.c.
2019 * Removed all _internal.h #includes from public header
2020 files. Internal headers must never be included from
2023 Removed also the lib/silcske/payload_internal.h file.
2025 * All include files that may be needed (public and some others
2026 included by the public headers) by application developers are
2027 now copied to the ./includes directory. It does not copy any
2028 internal headers. Affected file Makefile.defines.pre and all
2029 Makefile.am's under lib/ and subdirs.
2031 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Do not change the ~/.silc directory's permissions automatically.
2034 Affected file irssi/src/silc/core/clientutil.c.
2036 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2038 * Do not cancel the protocol in silc_server_close_connection
2039 it might cause recursion. Now cancelled in the function
2040 silc_server_free_sock_user_data. Affected file silcd/server.c.
2042 * Fixed the silc_server_remove_clients_by_server to regenerate
2043 the channel keys correctly finally. Added also new function
2044 silc_server_remove_clients_channels to actually do it.
2045 Affected file silcd/server.c.
2047 * Fixed the silc_server_new_channel to not crash by giving
2048 wrong router to the new channel. Affected file is
2049 silcd/packet_receive.c.
2051 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2054 which is given as argument to the silc_client_alloc now.
2055 It can be used to configure the client and set various parameters
2056 that affect the function of the client.
2058 * The USERS command in server did not check whether the channel
2059 is private or secret. Affected file silcd/command.c.
2061 * Added new argument to the USERS command in protocol specification.
2062 The USERS command now can take the channel name as argument
2063 as well. Added support for this in client and server and
2064 updated the protocol specs.
2066 * Completed the GETKEY command in client. It can be now used
2067 to fetch also servers public key not only some clients.
2068 Affected files lib/silcclient/command[_reply].c.
2070 * Added silc_client_get_server to return server entry by the
2071 server name. Affected files lib/silcclient/silcapi.h and
2074 * Redefined the IDENTIFY command in protocol specification to be
2075 more generic. It now can be used to query information about
2076 any entity in the SILC Network, including clients, servers and
2077 channels. The query may be based either the entity's name
2078 or the ID. Added support for this in both client and server.
2080 Affected files silcd/command.c and lib/silcclient/command.c
2081 and command_reply.c.
2083 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2084 the _from_client and _from_server functions. Affected file
2087 * Added silc_client_get_channel_by_id_resolve to the file
2088 lib/silcclient/silcapi.h to resolve channel information by
2089 its ID. Added also silc_client_get_channel_by_id that
2090 does not resolve it from the server.
2092 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2094 * Added SilcServerEntry context into the client library
2095 to represent one server. The INFO command now allocates
2096 these to save the resolved server info. For now on the
2097 client library will also keep information about servers,
2098 connected and resolved with INFO.
2100 The INFO command now allocates the SilcServerEntry context
2101 and saves the server info there. The COMMAND_REPLY in
2102 the INFO now returns the parameters to application in
2103 same order as defined in the protocol specification.
2105 The entries are cached in the client->server_cache.
2107 * The INFO command is now issued after received the Client ID
2108 from the server. Affected file lib/silcclient/client.c.
2110 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2111 to the application as the mode changer might be server.
2112 It is guaranteed that NULL is not returned anymore to the
2113 application. Affected file lib/silcclient/client_notify.c.
2115 The ID Type is now also passed to the application so that
2116 it can check whether the returned entry is SilcClientEntry
2119 Added new function silc_client_get_server_by_id to return
2120 the server entry by ID. Affected files are the
2121 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2123 * Do not create the channel in the Irssi SILC Client when issuing
2124 the JOIN command but when received the sucessful JOIN command
2125 reply. Otherwise the channel might get created even though we
2126 could not join it. The Affected file is
2127 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2129 * Fixed a channel joining bug in router. The router must also
2130 check the channel modes, invite and ban lists etc. when serving
2131 the JOIN command sent by normal server. Affected file is
2132 silcd/command.c. The router now resolves the client's
2133 information from the server who sent the JOIN command if it
2134 does not know it, and processes the JOIN command only after
2137 * Changed the SilcCommandCb to take new argument; void *context2.
2138 Affected file lib/silccore/silccommand.h
2140 The second argument in the command callbacks in the server now
2141 includes the SilcServerCommandReplyContext if the command was
2142 called as pending command callback from the command reply.
2143 Otherwise it is NULL. When called as pending the status of the
2144 command reply will be checked and if it was erronous the
2145 error will be sent to the original sender of the command.
2146 This way the client always receives the error messages even
2147 though the server was actually the one who received the error
2148 when it resent the command to router, for example. Affected
2149 files silcd/command[_reply].[ch].
2151 * Fixed sending WHOWAS command's error message to client if
2152 the requested client could not be found. It was missing.
2155 * Changed the CMODE and CUMODE commands reply arguments in the
2156 protocol specification. The Channel ID is now sent in both
2157 of the commands to identify the channel. Implemented this
2158 new feature to the client and server. Affected files
2159 lib/silcclient/command_reply.c and silcd/command.c.
2161 * Made better checks for invite and ban lists in the JOIN
2162 command in server. Affected file silcd/command.c.
2164 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2166 * The server now performs the incoming host IP/DNS lookup
2167 using the silc_socket_host_lookup and thus does not block
2168 the server anymore. Affected file silcd/server.c.
2170 * Completed the multi-thread support for SILC Scheduler in
2171 the lib/silcutil/silcschedule.c.
2173 * Fixed the configure.in.pre to detect the pthread correctly
2176 * Fixed a deadlock in silc_task_queue_wakeup in the file
2177 lib/silcutil/silctask.c.
2179 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2181 * Added new function silc_schedule_wakeup that is used in
2182 multi-threaded environment to wakeup the main thread's
2183 schduler. It needs to be used when a thread adds a new task
2184 or removes a task from task queues. After waking up, the
2185 scheduler will detect the task queue changes. If threads
2186 support is not compiled in this function has no effect.
2187 Implemented the wakeup mechanism to both Unix and WIN32
2188 systems. Affected files are lib/silcutil/silcschedule.[ch],
2189 lib/silcutil/unix/silcunixschedule.c and the
2190 lib/silcutil/win32/silcwin32schedule.c.
2192 * Added new function silc_task_queue_wakeup to wakeup the
2193 scheduler by the specified task queue. Affected file
2194 lib/silcutil/silctask.[ch].
2196 * The silc_socket_host_lookup_start now wakes up the scheduler
2197 after adding the timeout task. Affected file is
2198 lib/silcutil/silcsockconn.c.
2200 * The silc_socket_host_lookup is synchronous now if the threads
2201 support is not compiled in. However, the callback is still
2202 called asyncronously through the scheduler, anyway. Affected
2203 file lib/silcutil/silcsockconn.c.
2205 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2207 * Added new function silc_socket_host_lookup to perform
2208 asynchronous IP and FQDN lookups for the socket connection.
2209 Affected files lib/silcutil/silcsockconn.[ch].
2211 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2213 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2214 that may or may not compile the mutex support in.
2216 Changed the silc_mutex_alloc interface. It allocates the
2217 mutex now to the sent pointer and returns TRUE or FALSE.
2219 Affected file lib/silcutil/silcmutex.h.
2221 * Wrote the SILC Task Queue interface to support multi-threads.
2222 Affected file lib/silcutil/silctask.[ch].
2224 * Wrote the SILC Scheduler to support multi-threads. Affected
2225 file lib/silcutil/silcschedule.c.
2227 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2229 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2230 in lib/silcutil/win32/.
2232 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2234 * Defined SILC Mutex API and SILC Thread API and implemented
2235 them for Unix. Affected files are
2236 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2237 lib/silcutil/unix/silcunixmutex.c and
2238 lib/silcutil/unix/silcunixthread.c.
2240 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Fixed the silc_server_remove_clients_by_server's channel
2243 key re-generation. The hash table handling was incorrect
2244 and would not work with many channels. Affected file is
2247 * Fixed some memory leaks around the server code.
2249 * Rewrote the silc_server_get_users_on_channel to support IPv6
2250 based Client ID's. Affected file silcd/server.c.
2252 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2253 specification. However, a separate document must be written
2254 to define the detailed signing procedure and the payload
2255 associated with the flag. Defined the flag to the
2256 lib/silccore/silcchannel.h as well.
2258 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2260 * Changed the dynamic tables to static size tables in the
2261 lib/silccrypt/silchmac.c.
2263 * Removed GCC dependencies from the code. A patch by cras.
2265 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Do not show the error "Error receiving packet bla bla"
2268 in server if it really was not an error (-2 means that reading
2269 is pending). Affected file silcd/server.c.
2271 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Fixed a possible crash in silc_server_remove_clients_by_server
2274 in silcd/server.c. Fixed there also some memory leaks.
2276 * Fixed the silc_idlist_replace_client_id. It could replace
2277 wrong key in the hash table. Affected file silcd/idlist.c.
2279 * Do not check whether there are global users on the channel
2280 if the channel->global_users is FALSE. Affected functions
2281 silc_server_remove_from_one_channel and
2282 silc_server_remove_from_channels in silcd/server.c. Also,
2283 do not check if the removed client is local as we can be
2284 sure that global client was not removed from the channel
2285 and checking for global users is not needed.
2287 * The silc_server_remove_clients_by_server now re-generates
2288 the channel keys correctly for those channels that had
2289 clients removed from them. Affected file silcd/server.c.
2291 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Found the reason of random crashes in the server. We weren't
2294 ignoring the SIGPIPE signal (which can be sent in write())
2295 and it crashed the server. Affected file silcd/silcd.c.
2297 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2299 * Assure that sock->user_data is not NULL in the function
2300 silc_server_packet_send in silcd/packet_send.c.
2302 * Disconnect the remote connection if it could not be added
2303 to any ID lists in the server. The affected file is
2306 * Check in silc_server_packet_send[_real/dest] that the
2307 socket is not disconnecting and ignore the data if it is.
2308 Affected file silcd/packet_send.c.
2310 * Define inline to __inline on native WIN32 compilation.
2311 Affected file includes/silcwin32.h.
2313 * Added some explicit type casts for inline code since MSVC
2314 require them. Affected files lib/silcutil/silcbuffer.h,
2315 lib/trq/silcdlist.h and lib/trq/silclist.h.
2317 * Print warning in log files from now on if the packet
2318 decryption fails. Affected file silcd/server.c.
2320 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2322 * Changed the `say' client operation's interface to accept
2323 new `type' argument to indicate the type of the message sent
2324 by the library. The application may filter the library's
2325 messages according the type. The affected file is the
2326 lib/silcclient/silcapi.h.
2328 * Added two new functions to lib/silcclient/silcapi.h:
2329 silc_client_del_client and silc_client_del_client_by_id.
2330 Affected file lib/silcclient/idlist.c.
2332 * Moved the clientincludes.h from includes/ to silc/ and
2333 serverincludes.h from includes/ to silcd/.
2335 * The modes for the CMODE and CUMODE are now passed as
2336 uint32 for application with COMMAND_REPLY. The affected
2337 file is lib/silcclient/command_reply.c.
2339 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * /WHOIS without arguments shows client's own information.
2342 Affected file lib/silcclient/command.c.
2344 * Changed PING to not accept any arguments. The specs
2345 says that client can ping only the connected server so
2346 requiring an argument is not needed. Affected file is
2347 lib/silcclient/command.c.
2349 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2351 * Fixed a fatal bug in private message sending and reception
2352 encryption and decryption when using private message keys.
2353 The implementation was incorrect and did not follow the
2354 specification. It causd that some of the message were
2355 lost since it did not use the sending and receiving keys
2356 as the protocol suggests. This has been fixed and will cause
2357 incompatibilities with older clients when sending private
2358 message encrypted with private message keys. Affected files
2359 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2360 and various other in Irssi SILC Client.
2362 Added `responder' boolean argument to the functions
2363 silc_client_add_private_message_key[_ske] to indicate when
2364 the key is added as responder or initiator of the key
2367 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Removed the silc_ske_check_version function and created
2370 a SilcSKECheckVersion callback. Added also a function
2371 silc_ske_set_callbacks that is now used to set all SKE
2372 callbacks. The callback functions are not given to
2373 the SKE functions anymore, but this function is used to
2376 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2378 * Added `silc_version' argument to the silc_client_alloc
2379 to define the version of the application for the library.
2380 The library will use the version string to compare it
2381 against the remote host's (usually a server) version
2382 string. Affected file lib/silcclient/silcapi.h
2384 * Added the KE protocol context to Key Agreement context
2385 in client library so that we can abort the SKE if it
2386 is in process when we get timeout. Affected file is
2387 lib/silcclient/client_keyagr.c.
2389 * Do not resolve the client ID forever if it returns in the
2390 first time that such client does not exist. This was done
2391 for example with private message. Affected file is
2392 lib/silcclient/client_prvmsg.c.
2394 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Do not add regex.h for WIN32. The affected file
2397 includes/silcincludes.h.
2399 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2400 not work yet 100%. It generates the DLL's automatically
2401 when compiling with --with-win32 under cygwin.
2403 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * lib/contrib/regex.c is not compiled on WIN32.
2407 * Added silc_net_get_socket_opt function to the
2408 lib/silcutil/silcnet.h.
2410 * Added includes/silcwin32.h for WIN32 specific includes
2413 * Do not use ptime structure or any of the posix process
2414 functions on WIN32 in lib/silccrypt/silrng.c.
2416 * Added silc_gettimeofday to provide generic function
2417 for struct timeval on all platforms. Added the function
2418 to lib/silcutil/silcutil.h.
2420 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2422 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2423 library as they clearly belong there. As a plus side we
2424 can make the actual socket connection routines platform
2427 Added also new generic function silc_socket_read and
2428 silc_socket_write (that used to be silc_packet_[read/write].
2429 The implementation of these are platform specific.
2431 * Added WIN32 specific routines of silc_socket_[read/write]
2432 to lib/silcutil/win32/silcwin32sockconn.c.
2434 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Added preliminary support for native WIN32 compilation under
2437 cygwin (using the -mno-cygwin option for GCC) to the
2438 ./configure.in.pre. The --with-win32 now prepares the
2439 compilation for native WIN32.
2441 * Rewrote the SILC Scheduler interface in the file
2442 lib/silcutil/silcschedule.h. The scheduler is now context
2443 based and does not have anymore any global static scheduler.
2444 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2445 and created lib/silcutil/win32 directory for WIN32 based
2448 * Added Unix specific network routines to the
2449 lib/silcutil/unix/silcunixnet.c and the old
2450 lib/silcutil/silcnet.c includes now only generic routines.
2452 Added WIN32 specific network routines to the
2453 lib/silcutil/win32/silcwin32net.c.
2455 * Added Unix specific utility functions from the
2456 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2458 * Added WIN32 SILC Scheduler to the file
2459 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2462 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Do not handle JOIN notify in the server if the target client
2465 is not registered (idata->registered == FALSE). The affected
2466 file is silcd/packet_receive.c.
2468 * Update the nickrec->founder in event_cumode in the Irssi SILC
2469 client. Affected file irssi/src/silc/core/silc-channels.c.
2471 * Fixed the CUMODE_CHANGE notify handling in the server when
2472 server and router are announcing their clients on channels.
2473 Now the mode changes are saved and notified correctly. The
2474 affected file is /silcd/packet_receive.c.
2476 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2477 They really did not replace the cache entry in the ID Cache.
2478 Now they do that. Affected file silcd/idlist.c.
2480 * Fixed the KICK notify handling in the Irssi SILC client to
2481 update the channel records so that the kicked client does not
2482 appear to be on the channel. The affected file is
2483 irssi/src/silc/core/silc-channels.c.
2485 * Always update the conn->current_channel when executing command
2486 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2488 * Fixed the KILL notify handling in Irssi SILC client to remove
2489 the killed client on all channels.
2491 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Fixed the silc_parse_command_line to remove extra spaces
2494 from the start and end of the arguments. Affected file is
2495 lib/silcutil/silcutil.c.
2497 * Cancel and free any active protocol in the function
2498 silc_server_close_connection. Affected file silcd/server.c.
2500 * Cancel and free any active protocol in the function
2501 silc_client_close_connction. Affected file is
2502 lib/silcclient/client.c.
2504 * Do not execute the KILL command for clients that are in
2505 history (ie. they are not in the network). Affected file is
2508 * Fixed KILL notify handling, client does not crash anymore.
2509 Affected file irssi/src/silc/core/silc-channels.c.
2511 * Reduced the default packet buffer size from 2048 to 1024 in
2512 lib/silccore/silcpacket.c.
2514 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2515 counter to the SKE context that is incresed when the SKE library
2516 performs async operation outside the library. If the outside
2517 process frees the SKE context and FREED status will be set
2518 and the library will detect after the sync operation that the
2519 libary is freed. The affected files are
2520 lib/silcske/silcske[_status].[ch].
2522 * Resolve the client entry information in the function
2523 silc_client_channel_message to assure that NULL pointer is not
2524 passed as client entry to the application. */
2526 * Fixed the task timeout calculation to assure that there is
2527 never negative timeouts. The affected file is
2528 lib/silcutil/silcschedule.c.
2530 * Fixed the channel user mode notification sending in server.
2531 It was sent point-to-point to the router (or to server by router)
2532 but it needs to be destined to a channel. The routines now
2533 supports sending the channel user mode notifys to the channels
2534 when announcing clients and channels. Affected files are
2535 silcd/server.c and silcd/packet_receive.c.
2537 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2538 It did not actually replace the old channel entry in the cache.
2539 Affected file lib/silcclient/client_notify.c.
2541 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2543 * Fixed a possible crash in silc_packet_send_prepare. It now
2544 assures always that there is enough space in the buffer and
2545 at the tail area of the buffer (for MAC).
2547 Fixed the inbound buffer reallocation in silc_packet_read.
2548 It was old code and did not handle the reallocation correctly.
2551 The affected file is lib/silccore/silcpacket.c.
2553 * Fixed buffer overflow in silc_parse_nickname in the file
2554 lib/silcutil/silcutil.c.
2556 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * make install generates new server keys only if there is not
2561 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2563 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2564 Added check that if the NOREPLY is set then we will not send
2565 the away message. This avoids infinite loop of away messages
2566 if both clients are away. The affected file is
2567 lib/silcclient/client_prvmsg.c.
2569 * Fixed client crash if /NICK was given without arguments.
2570 Affected file lib/silcclient/command.c.
2572 * Server does not send the invite list in INVITE command back
2573 to the client if the list was not altered. Added this notion
2574 to the protocol spec as well. Affected file silcd/command.c.
2576 Fixed possible crash in INVITE command by checking the
2577 value of silc_server_get_client_route command.
2579 * Fixed the INVITE notify type handling. The arguments are now
2580 taken in correct order and client does not crash. The affected
2581 file is irssi/src/silc/core/silc-channels.c.
2583 Removed the "Inviting xxx to channel" message from the
2584 client library away and let the application handle it.
2585 Affected file lib/silcclient/command.c. Added that message
2586 to Irssi SILC client's message formats.
2588 * Fixed CMODE command crash in client. It now checks the
2589 amount of arguments correctly and does not crash. The affected
2590 file is lib/silcclient/command.c.
2592 * Do not create new channel automatically in silc_channels_join
2593 but check whether the channel by that name already exists.
2594 Affected file irssi/silc/core/silc-channels.c.
2596 * Do not send the SERVER_SIGNOFF to router if the disconnected
2597 entity was the router. Affected file silcd/server.c.
2599 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2600 SILC client as it was missing from there.
2602 Added the handling of the KICK notify to the Irssi SILC client
2603 as it was missing. Added "you have been kicked" message to
2604 Irssi SILC client's message modules formats.
2606 Added the handing of the KILL notify to the Irssi SILC client
2607 as it was missing. Added the kill message module formats
2610 The affected file is irssi/src/silc/core/silc-channels.c.
2612 * The router did not save the channel mode the server announced.
2613 Affected file silcd/packet_receive.c.
2615 * Fixed a possible crash in INFO command in server. If the
2616 server did not provide the server info it crashed. Affected
2617 file silcd/command.c.
2619 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2621 * Fixed the GETKEY command in the server to check also the
2622 global list. Otherwise the GETKEY would not work correctly
2623 in normal SILC server. Affected file silcd/command.c.
2625 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Fixed GETKEY crash, it crashed if the command did not succseed.
2629 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2632 is now real and not just an macro interface to GMP.
2634 Removed the entire GMP from the source tree and imported new
2635 NSS MPI library instead. Reason for removing GMP is that it is
2636 extremely large and compiles extremely slow. The NSS MPI
2637 is only a few files and compiles in less than 10 seconds.
2638 The speed is also about the same as GMP. The MPI is imported
2639 to lib/silcmath/mpi.
2641 If the system has GMP installed we will still use the GMP.
2642 If it is not then the NSS MPI will be compiled.
2644 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2646 * Merged a long nickname (127 characters long) crash bugfix from
2647 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2649 * Merged a freed memory reference bugfix from Irssi CVS tree.
2650 Affected file irssi/src/core/commands.c.
2652 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2654 * Added the server's public key sving and verification to the
2655 server when performing the SKE. This was missing and the
2656 remote server's (or router's) public key was accepted without
2657 checking whether we have it previously or trust it at all.
2658 Affected file silcd/protocol.c.
2660 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2662 * Check in the silc_server_timeout_remote if protocol is active
2663 and make sure that the protocol's final callback is called so
2664 that all memory if freed. Affected file silcd/server.c.
2666 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * silc_server_whois_send_reply crashed the server if the nickname
2669 was 127 characters long. Affected file silcd/command.c.
2671 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2673 * Added sanity check to the silc_server_new_client. If the hostname
2674 is provided inside username then check that the provided hostname
2675 really is the same as the resolved one. If the hostname was not
2676 resolved then check it from the public key. Affected file is
2677 silcd/packet_receive.c.
2679 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2680 if the server disconnected us and the connection is not valid
2681 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2683 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2684 the library to the lib/silcutil/silcutil.[ch].
2686 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * Close log file after open. Affected file
2689 lib/silcutil/silclog.c.
2691 * Check whether sock == NULL in silc_client_send_packet and return
2692 if it is. Affected file lib/silcclient/silcclient.c.
2694 * Check rec->entry == NULL in the Irssi SILC Client before
2695 sending the channel message. Affecte file is
2696 irssi/src/silc/core/silc-servers.c.
2698 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2700 * Merged a splitted window bugfix from Irssi CVS tree. The
2701 affected file is irssi/src/fe-text/textbuffer-view.c.
2703 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2704 It did not print nickname.
2706 * Improved the distributions system a bit.
2708 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2710 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2711 irssi/src/fe-text/gui-window.c.
2713 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2714 to in-active server. The affected file is
2715 irssi/src/silc/core/client_ops.c.
2717 * Resolve the client in USERS command reply if the entry does
2718 not have username resolved. The affected file is
2719 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2720 command to WHOIS command to really resolve stuff. The USERS
2721 is not used any more in any critical section so WHOIS can
2722 be used even though it might be slower than IDENTIFY.
2724 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2727 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2729 * Changed the protocol API a bit more consistent in the
2730 lib/silccore/silcprotocol.[ch].
2732 * Changed the following headers to ROBODoc format:
2734 lib/silccore/silcpayload.h
2735 lib/silccore/silcprotocol.h
2736 lib/silccore/silcsockconn.h
2738 All core library headers are now formatted.
2740 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2742 * Fixed a bug in Irssi SILC client; do not show that you are
2743 server/router operator if you really are not. Affected file is
2744 irssi/src/silc/core/client_ops.c.
2746 * Renamed silc_command_free_payload to silc_command_payload_free.
2747 Affected file lib/silccore/silccommand.h
2749 * Added silcmath.h to include the prototoypes of various routines
2750 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2753 * Changed the following headers to ROBODoc format:
2755 lib/silccore/silcchannel.h
2756 lib/silccore/silccommand.h
2757 lib/silccore/silcid.h
2758 lib/silccore/silcidcache.h
2759 lib/silccore/silcmode.h
2760 lib/silccore/silcnotify.h
2761 lib/silccore/silcpacket.h
2762 lib/silcmath/silcmath.h
2764 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Added checking to the server code not to start the server if
2767 ciphers and stuff are not configured properly. Affected files
2768 silcd/serverconfig.[h] and silcd/server.c.
2770 * Changed the layout of the header files of the public interfaces
2771 in the SILC libraries. The new layout supports ROBODoc
2772 documentation tool (and some others) so that it is easy to create
2773 a library reference manual. All the other headers and source
2774 code must still follow the CodingStyle document. Also source
2775 code must not include these ROBODoc stuffs, only the headers.
2776 Furthermore, all public interface headers must now be named
2777 by using `silc' prefix, example: silcapi.h, silccipher.h.
2778 Some files were renamed due to this. All the other headers
2779 must not be used as public interfaces. I will update the
2780 CodingStyle document later. Changed following headers, so far:
2782 lib/silcclient/silcapi.h
2783 lib/silccore/silcauth.h
2784 lib/silccore/silcprivate.h
2785 lib/silccrypt/silcdh.h
2787 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Removed silc_client_packet_send_flush from the client library
2792 as it is not needed. Affected file lib/silcclient/client.[ch].
2794 * Added printing of message of unresolved authentication method
2795 to the Irssi SILC client. Added it to the module formats.
2796 Removed the same message from the client library.
2798 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Added new distribution feature, DISTLABEL. Every distribution
2801 can define own preprocessor label that can be used in the
2802 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2803 file distributions, acconfig.h.pre and prepare.
2805 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2807 * Added Makefile.defines_int to include the actual definitions
2808 for Makefile.defines.in. Tested the new distribution system,
2809 created distributions and tested installation.
2811 * Added AWAY message printing to the Irssi SILC client. Added
2812 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2814 * Added SCONNECT command to call the SILC's CONNECT command.
2815 Cannot use CONNECT directly since Irssi uses that internally.
2816 Affected file irssi/src/silc/core/silc-servers.c.
2818 Added ACTION local command. It is same as ME command but takes
2819 the channel as mandatory argument.
2821 Rewrote some of the Irssi's help files to suite for SILC
2824 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2826 * Added Makefile.defines[.in] that should for now on be included
2827 in all Makefile.am file in the source tree. That file includes
2828 all common compilation definitions for SILC source tree.
2830 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2832 * Minor changes to the ./prepare script to change the package
2833 name according the distribution name to the configure.in.
2835 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2837 * Created new distribution system. Added file `distributions'
2838 that defines all the distributions that can be created out of
2839 the SILC source tree. The ./prepare script now reads that
2840 file to determine how to prepare the distributions. The
2841 first argument to the ./prepare is the name of the distribution
2842 and second is the version of the distribution. If given
2843 without arguments it creates the default (toolkit) distribution
2844 with the default version (defined in ./prepare).
2846 All Makefile.am files that are subject to the distributions
2847 are now named as Makefile.am.pre. These are ./Makefile.am
2848 and lib/Makefile.am. Others may be changed later.
2850 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Added invite list, ban list, some key management and connection
2853 error message printing to module formats in the Irssi SILC client.
2855 * Added new silc_client_set_away_message to set the away message
2856 that is back to the person who sent private message. The
2857 affected file lib/silcclient/silcapi.h and the
2858 lib/silcclient/client_prvmsg.c.
2860 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2862 * Fixed the private message sending in the Irssi SILC client,
2863 added local command KEY to the Irssi SILC client.
2865 Added key management and key agreement message formats to the
2866 irssi/src/fe-common/silc/module-formats.[ch].
2868 Added USERS (alias WHO) printing, server/router operator
2869 indication and LIST command printing to the module formats.
2871 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * Fixed channel joining notify handling, cumode notify handling
2874 from Irssi SILC client.
2876 * Added SILC specific module-formats to the Irssi SILC client so
2877 that SILC specific message hilighting, colors etc is possible.
2878 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2880 Added channel mode, channel user mode, actions, notices,
2881 whois and whowas printing to the the module-formats.c.
2883 * Fixed a bug in channel deletion in the server. The channel
2884 is not left to the cache even if the channel founder auth mode
2885 is set when there are no users anymore on the channel. Affected
2886 file silcd/server.c.
2888 * The silc_net_localhost now resolves the entire hostname including
2889 the domain name. Affected file lib/silcutil/silcnet.c.
2891 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Changed the ask_passphrase client operation to be ascynchronous.
2894 It has now a completion callback and a context that the
2895 application must call after it has got the passphrase from
2896 the user. Affected files lib/silcclient/silcapi.h,
2897 lib/silcclient/protocol.c, lib/silcclient/command.c and
2900 Added SilcAskPassphrase callback that the application calls
2901 to deliver the passphrase to the library.
2903 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2904 The public key verification and especially a certificate
2905 verification is asynchronous procedure.
2907 Added new SILC_SKE_STATUS_PENDING status to indicate the
2908 request is pending and a callback will be called to finalize
2911 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2912 indicate that remote end did not send its public key (or
2913 certificate), even though we require it. Added check for this
2914 condition in the SKE. This was a security bug, now fixed.
2916 Defined new SilcSKEVerifyCbCompletion callback that is called
2917 when the verification process is completed.
2919 The affected files lib/silcske/silcske_status.h and
2920 lib/silcske/silcske.[ch].
2922 * Changed the verify_public_key client operation to be async
2923 as well. Defined SilcVerifyPublicKey callback that is used to
2924 indicate the success of the public key verification process.
2926 Changed the server and client to use the new async client
2929 * Changed the Irssi SILC client's internal scheduler to be called
2930 twice as many times as it used to be. As a result the client
2931 should be a bit faster now. Affected file is
2932 irssi/src/silc/core/silc-core.c.
2934 * Added support to Irssi SILC client of asynchronous public key
2935 verification and passphrase inquiry. Affected file is
2936 irssi/src/silc/core/silc-core.c.
2938 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * Do not say "You have left channel %s" in client library.
2941 Moved it to the application. Affected files are
2942 lib/silcclient/command.c and silc/client_ops.c.
2944 * Fixed silc_client_get_clients. Command context was not
2945 duplicated and was freed memory in the callback. Affected
2946 file lib/silcclient/idlist.c.
2948 * Do not say "you are now talking..." on JOIN command in the
2949 client library. The appliation must handle it.
2951 * Do not say ".. changed topic to" in command reply in the
2952 client libary. The application must handle it.
2954 * Fixed TOPIC command sending in the client library.
2956 * Fixed a memory leak in silc_client_command_free in the file
2957 lib/silcclient/command.c.
2959 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2961 * Imported a modified version of Irssi client to the source tree.
2962 The Irssi will be used to create a new client called
2963 Irssi SILC. Imported to irssi/.
2965 Added silc_core_init_finish function to the Irssi. Affected
2966 file irssi/configure.in.
2968 A lot changes in the Makefile.ams around the irssi tree.
2970 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2972 * Do not rehash if the new size is same as the old size of the
2973 hash table, in the silc_hash_table_rehash*. The affected file
2974 lib/silcutil/silchashtable.c.
2976 * Replaced hash_table_del_by_context calls from the server
2977 (when channel->user_list and client->channels) to the
2978 hash_table_del as it is sufficient and faster.
2980 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Added silc_hash_table_list, silc_hash_table_get and the
2983 SilcHashTableList structure to provide an alternative way to
2984 traverse the hash table. The affected files are
2985 lib/silcutil/silchashtable.[ch].
2987 * Changed the server's idlist routines to use the hash table
2988 routines to optimize the code.
2990 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Replaced the client entry's `channel' list and channel entry's
2993 `user_list' list to hash tables for optimized lookup. Changed
2994 the code to use the hash table interface around the code.
2995 Affected file lib/silcd/idlist.[ch].
2997 * Added `auto_rehash' boolean argument to the function
2998 silc_hash_table_alloc to indicate whether the hash table should
2999 auto-rehash when it thinks is appropriate time. It will
3000 increase the hash table size if the there is twice as much
3001 entries in the table than the size of the table, and will
3002 decrease the size if there are twice as less entries than
3003 the size of the table.
3005 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3009 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * silc_idcache_purge_by_context deletes the entry now by context
3012 as it is supposed to do. Affected file lib/silccore/idcache.c.
3014 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3015 client is not anymore valid (WHOWAS givens the info) and not
3016 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3018 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3020 * Removed the `data' and `data_len' arguments from the ID Cache
3021 interfaces and added `name' argument. ID Cache does not handle
3022 anymore the binary data only a names associated with given ID.
3024 * When hashing a Client ID with silc_hash_id the entire ID is
3025 not hashed anymore, instead only the hash of the Client ID is
3026 hashed. This way we can access the Client ID from the cache
3027 with Client ID but with the hash of the ID (which is a hash of
3028 the nickname) as well without any difference in performance.
3030 Added also silc_idcache_find_by_id_one_ext to do one on one
3031 searching when we have the actual ID. Added also function
3032 silc_hash_client_id_compare. The affected files are
3033 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3035 * When hashing the name associated with a ID it is always done
3036 in lowercase. This way we can access the cache without worrying
3037 about case-sensitivity, even though, for example nicknames are
3040 * Fixed a bug in server with channel message sending. It put
3041 wrong ID type as destination ID. The affected file
3042 silcd/packet_send.c.
3044 * silc_idcache_del_by_context now deletes from all hash tables
3045 by context. Affected file lib/silccore/idcache.c.
3047 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Changed the client library to use the new ID Cache interface.
3050 Changes around the source tree.
3052 * Added silc_hash_table_rehash_ext to rehash with specific
3053 hash function. Affected file lib/silcutil/silchashtable.[ch].
3055 * Added silc_hash_string_compare to compare two strings in the
3056 hash table. Affected file lib/silcutil/silcutil.[ch].
3058 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3060 * Added new function silc_idcache_del_by_context into the
3061 lib/silccore/idcache.[ch].
3063 * Changed the server's ID list routines to use the new ID Cache
3064 interface. Changes around the source tree.
3066 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3068 * Added silc_hash_table_del[_by_context]_ext functions in to the
3069 lib/silcutil/silchashtable.[ch].
3071 Removed silc_hash_table_find_all* routines and added new
3072 silc_hash_table_find_foreach to replace them.
3074 Added silc_hash_table_replace_ext function as extended
3075 replacing function. Separated the simple hash table interface
3076 from the extended hash table interface in the file
3077 lib/silcutil/silchashtable.h.
3079 * Fixed minor bugs and changed it to use some of the new
3080 hash table functions in lib/silccore/idcache.c
3082 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3084 * Added new function silc_hash_table_find_all to return all keys
3085 in the hash table by the specified key. As the hash table is
3086 collision resistant it also makes it possible to have several
3087 duplicate keys in the hash table. This function may be used to
3088 find all of the keys from the hash.
3090 Added user_context arguments to the SilcHashFunction,
3091 SilcHashCompare and SilcHashDestructor to deliver user specified
3094 Added new fuctions silc_hash_table_find[_all]_ext to do
3095 extended lookup with specified hash and compare functions and
3096 specified user contexts.
3098 Added new function silc_hash_table_add_ext to add the key
3099 with specified hash function and user context.
3101 Added new function silc_hash_table_foreach to traverse all
3102 entrys in the hash table. Added SilcHashForeach callback
3105 Added new function silc_hash_table_del_by_context to delete
3106 the entry only if the context associated with the key matches.
3108 Affected files are lib/silcutil/silchashtable.[ch].
3110 * Removed silc_hash_[server/client/channel]_id and added just
3111 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3112 silc_hash_id_compare to compare two ID's using as the hash table
3113 comparison function. Added also silc_hash_data to hash
3114 binary data and silc_hash_data_compare to compare it.
3116 * Removed silc_idlist_find_client_by_hash as it is not needed
3117 anymore. Affected file silcd/idlist.[ch].
3119 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3120 to use internally the SilcHashTable. The new ID Cache is a lot
3121 faster than the old one. Some of the ID Cache interface was also
3122 rewritten and obsolete and stupid functions were removed.
3124 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3126 * Added entry_count field to the SilcHashTable to keep the number
3127 of the entries in the table. Implemented the function
3128 silc_hash_table_rehash. Added new function
3129 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3131 Fixed a minor bug in silc_hash_table_free.
3133 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3134 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3135 into the lib/silcutil/silcutil.[ch].
3137 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Implemented a collision resistant hash table into the
3140 lib/silcutil/silchashtable[ch]. See the header and the source
3141 for the SilcHashTable API.
3143 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Merged dotconf version 1.0.2 into lib/dotconf.
3147 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * Do not compile anything in lib/silcsim/* if the SIM support
3150 is not enabled. The tree should now compile without problems
3153 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3155 * Compiled the SILC under cygwin. Compiled and tested briefly
3156 without problems. More tests needed. The SIMs didn't compile
3159 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3161 * Fixed possible crash in silc_get_username in the
3162 lib/silcutil/silcutil.c.
3164 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Fixed a va_arg in silc/client_ops.c.
3168 * Oops, RC5 routines were named AES and caused some problems
3169 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3171 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3173 * Added new SilcIDIP structure into the lib/silccore/id.h and
3174 replaced the old `ip' fields from all SILC ID's to that type.
3175 This is a step towards IPv6 support.
3177 The silc_id_get_len takes now the ID as an extra argument.
3178 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3179 both IPv4 and IPv6 based ID's.
3181 The affected files are lib/silccore/id.[ch] and other files
3182 around the tree using these routines.
3184 * Removed the ID length arguments in server from various
3185 silc_server_send_notify_* routines -> they are not needed
3188 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Fixed memory leak in silc_encode_pem_file in the file
3191 lib/silcutil/silcutil.c.
3193 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Check minor version as well in the SKE. Affected files are
3196 silcd/protocol.c and lib/silcclient/protocol.c.
3198 * Added --identifier option to the server so that an identifier
3199 can be when creating the public key for the server. Affected
3200 file is silcd/silcd.c.
3202 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3203 lib/silccrypt/silcpkcs.c.
3205 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Register default ciphers and stuff when using -C option with
3208 the server. Affected file sildc/silcd.c.
3210 * Put back the servers public key filename format, it is better
3211 than the new one. For now, the client keys are saved with the
3212 new filename format. The affected file silc/client_ops.c.
3214 * Implemented the Cipher API for the rest of the ciphers that
3215 did not implement it or implemented it the wrong way.
3217 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Register default ciphers and stuff when using the -S option
3220 in the client. Affected file silc/silc.c. Same also when
3221 creating new key pair with -C option.
3223 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3225 * Fixed the silc_verify_public_key client operation function to
3226 save the public keys differently. The fingerprint is now
3227 used as filename and not the hostname. This way also the
3228 client keys are saved uniquely and not with hostnames. The
3229 affected file is silc/client_ops.c.
3231 * Trimmed the silc_hash_fingerprint function to remove extra
3232 whitespaces from the end of the fingerprint. The affected
3233 file is lib/silccrypt/silchash.c.
3237 * Added silc_cipher_register_default function to register all
3238 default ciphers. It can be used when configuration files
3239 does not exist and the application does not want any specific
3240 ciphers in any specific order.
3242 The SilcDList is now used as silc_cipher_list dynamically
3243 allocated cipher list. Removed the static list all together
3244 and now all ciphers must be allocated to the dynamic list.
3245 The silc_cipher_alloc routine was changed to check only the
3248 All silc_cipher_* routines that used to return int returns
3251 The affected files lib/silccrypt/silccrypt.[ch].
3253 * The same thing was done to silc_hash_* as for silc_cipher_*
3254 routines. Affected files lib/silccrypt/silchash.[ch].
3256 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3257 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3258 Added also silc_pkcs_[un]register[_default] functions.
3259 Removed the data_context from the PKCS API.
3261 * Added silc_hmac_register_default function to register default
3262 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3263 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3264 to unregister all hmacs at once.
3266 * Register the default ciphers, hash functions, PKCSs and HMACs
3267 if client's configuration file does not exist. The affected
3270 * The client did not load the hash functions from the SIM
3271 modules at all. Added support for this. Affected file is
3272 silc/clientconfig.c.
3274 * When decoding public key with silc_pkcs_public_key_decode, check
3275 the supported algorithm only if PKCS are registered. Affected
3276 file lib/silccrypt/silcpkcs.c. The same was done with the
3277 silc_pkcs_private_key_decode.
3279 * Fixed the SILC List routines to keep the list always in order.
3280 It used to change the list's order when traversing the list but
3281 not it preserves the order. Affected file lib/trq/silclist.h.
3283 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Added the client library to use the SilcSocketConnection's
3286 reference counter (by silc_socket_dup) to prevent the bug that
3287 the socket object may be freed underneath async operation.
3289 * The name resolv library checking fixes in the configure.in.pre.
3292 * Created new version of the protocol drafts for future
3293 development. The -03 drafts are the ones that will be changed
3294 in the trunk now and the -02 will remain as they are.
3296 * Send list of CUMODE notifys to the router when announcing
3297 the channel users to the router. Affected file silcd/server.c.
3298 If the router receiving channel founder CUMODE for a channel
3299 that already has channel founder it will send CUMODE notify
3300 to the sender to remove the channel founder rights from the
3301 announced client. Affected file silcd/packet_receive.c.
3303 * The CUMODE notify may now use Server ID as well as the entity
3304 who changes the mode. Updated protocool specs.
3306 * Updated INSTALL and README files.
3308 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * New web pages in the http://silc.pspt.fi. The pages was
3315 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3317 * Implemented the [DenyConnectin] config section in the server.
3318 Added silc_server_config_denied_conn to check whether incoming
3319 connection is denied. Affected file silcd/serverconfig.[ch].
3321 * Do not check the ports when checking the incoming configuration
3322 data if the port is 0, meaning any. Affected file is
3323 silcd/serverconfig.c.
3325 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Fixed buffer overflow in silc_string_compare in the file
3328 lib/silcutil/silcutil.c.
3330 * Fixed double free in silc_server_command_leave in the file
3333 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3335 * Fixed the version checking in the server. Affected file is
3338 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Fixed the configuration data fetching when accepting new
3341 connections in the server. Affected file silcd/server.c.
3343 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Added `sender_entry' argument to the function
3346 silc_server_packet_relay_to_channel so that we can check
3347 whether some destination actually belongs to the same route
3348 the sender belongs (ie, we must not resend the packet to the
3349 sender). Affected file silcd/packet_send.[ch].
3351 * Added `servername' field to the SilcClientEntry in the server
3352 to hold the name of the server where client is from. Affected
3353 file is silcd/idlist.h.
3355 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Moved the channel message encrypting in the router betwen
3358 router connections from silc_server_channel_message to the
3359 silc_server_packet_relay_to_channel since we want to check
3360 whether we have anybody channel before encrypting anything.
3361 Affected files silcd/packet_[receive/send].c.
3363 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * Fixed the [AdminConnection] server config section to support
3366 multiple entries. Affected file silcd/serverconfig.c.
3368 * Added support into the server to check the validity of the
3369 incoming connection before executing any KE or authentication
3372 * The connection configuration is now saved to the KE and
3373 connection auth protocol contexts and not fetched anymore in
3374 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3376 * The local hosts listenning address and port is also resolved
3377 now when starting the server. We want to have the socket object
3378 to include the real address and port for the listener. Added
3379 new function silc_net_check_local_by_sock into the files
3380 lib/silcutil/silcnet.[ch].
3382 * Fixed a broadcast bug in server -> do not broadcast if we
3385 * Fixed a routing bug. Do not route broadcast packets ever.
3386 Broadcast packets must be processed always and not routed since
3387 they may be destined to some other host than yourself and thus
3388 would get routed without no good reason. Affected file is
3391 * Added function silc_server_config_is_primary_route to check
3392 whether primary router connection has been configured (a router
3393 configuration that we are initiating). If there is not, we
3394 will assume that there is only two routers in the SILC network
3395 and we will use the incoming router connection as our primary
3396 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3398 * Changed the order of the broadcasting. Broadcast _after_ the
3399 packet has been processed not before. Affected file is
3402 * Fixed a [ClientConnection] parsing bug. The port was never
3403 parsed correctly thus resulting to port 0. Affected file
3404 silcd/serverconfig.c.
3406 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3407 argument and did not set the broadcast packet flag. Affected
3408 file silcd/packet_send.c. Fixed same bug in the function
3409 silc_server_send_notify as well.
3411 * If we receive NEW_ID packet for our own ID in the server, ignore
3414 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3418 * Removed the nickname from the Private Message Payload.
3419 Updated the code and the protocol specs.
3421 * Updated protocol specs for submitting to the IETF.
3423 * Tweaked the Random Number Generator a bit. Affected file
3424 lib/silccrypt/silcrng.c. Exported a new function
3425 silc_rng_[global]_add_noise which can be used to add more
3428 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Do not parse packets with different timeout when protocol
3431 is active -> may cause problem with rekey. Affected file
3434 * When server receives signoff notify it must not create
3435 new channel key if the client is on any channels since the
3436 sender of the signoff notify will create it.
3438 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Added printing of error messages during SKE protocol from the
3441 failure packet sent by server during SKE. Affected file
3444 * Removed the client's failure_callback handling with timeout
3445 and handle it immediately when received.
3447 * The SKE library returned wrong type in SUCCESS and FAILURE
3448 packets. They must be 32 bit MSB not 16 bit MSB.
3450 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Ok, rewrote the logic of the re-key and now it seems to work.
3453 I tested it on high traffic with frequent re-keys without
3454 problems. Added hmac_receive (and renamed hmac to hmac_send)
3455 in SilcClientConnection in lib/silcclient/client.h and
3456 in SilcIDListData in silcd/idlist.h. Also, removed the
3457 SilcPacketParserContext's cipher and hmac fields as they are
3458 not needed anymore and actually caused some problems when
3459 the ciphers and hmac's changed underneath the packet parser.
3461 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * If re-key protocol is active then process the incoming packets
3464 synchronously since we must assure that icoming packets encrypted
3465 with the old key is processed before the new keys is set to
3466 use. This is true other packets than for REKEY packets.
3467 Affected file silcd/server.c. The same was done to client library
3468 as well, affected file lib/silcclient/client.c.
3470 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * Fixed bug in client and server to accept the force send if
3473 the packet is send from silc_[server/client]_packet_process
3474 function. Otherwise the packets are never delivered, oops.
3476 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Disable force sending of packets when REKEY protocol is active.
3479 We must assure that no packet is sent directly when rekey is
3480 performed. All packets must be sent through packet queue.
3481 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3482 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3483 function is silc_[server/client]_packet_send_real to check
3486 * Replaced the SIM paths from example config files to
3487 /usr/local/modules. Also, make install creates now
3488 /usr/local/silc/logs directory to hold all the SILC server
3491 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Made the configure.in.pre work on Solaris. Patch by salo.
3495 * Made all ciphers compatible with non-x86 machines. Defined
3496 CBC mode macros into lib/silccrypt/ciphers_def.h.
3498 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Fixed the make install.
3502 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * When MAC computation fails the silc_packet_decrypt returned 0
3505 even though it was supposed to return -1. Fixed this. The
3506 affected file is lib/silccore/silcpacket.c.
3508 * Do not replace the config files in /etc/silc (in make install)
3509 if they already exist. Affected file ./Makefile.am.
3511 * Do not send re-key packets immediately but through packet queue.
3512 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3514 * Changed silc_net_check_host_by_sock to return FALSE if the
3515 IP/DNS could not be resolved. Though, it returns the IP address
3516 now even if it could not resolve it (but returns also FALSE).
3517 Affected file lib/silcutil/silcnet.[ch].
3519 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Added silc_pkcs_decode_identifier to decode the public key's
3522 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3523 Added also silc_pkcs_free_identifier. Added also new context
3524 SilcPublicKeyIdentifier.
3526 * Added -S option to the silc client. It is used to dump the
3527 contents of the specified public key file.
3529 * Changed the PKCS api to return the public key length when
3530 setting the public key.
3532 * Fixed a fatal bug in the public and private key file loading.
3533 Affected file lib/silccrypt/silcpkcs.c.
3535 * Execute the packet parsing for client with zero (0) timeout
3536 if the protocol is active. Affected file silcd/server.c.
3538 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * Made the key generation options to the silcd program. Added
3541 -C option, equivalent to client's option.
3543 * Added new [ServerKeys] config section to the server. It
3544 configures the server's public and private key.
3546 * Defined generic Public Key Payload into the protocol
3547 specification to send specific type of public keys and
3550 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3551 public key or certificate.
3553 * Implemented the GETKEY command to the server and to the
3554 client library and on user interface.
3556 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Made preliminary `make install' work.
3560 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3562 * Added SilcServerRekey context into silcd/idlist.h.
3564 * Added the PFS support as defined in the specification to the
3565 SKE protocol. Affected files lib/silcske/*.c.
3567 * Added `ske_group' field to the SilcServerRekey context to hold
3568 the number of the SKE group that is used with PFS in re-key.
3569 Affected file silcd/idlist.h.
3571 * Added PFS re-key support to the server. Affected file is
3574 * Added silc_protocol_cancel to cancel execution of the next
3575 state of the protocol. Affected file is
3576 lib/silccore/silcprotocol.[ch].
3578 * Added the re-key support with and without PFS to the client
3579 library. Re-key is performed once in an hour, by default.
3581 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3582 Added silc_client_rekey_callback and silc_client_rekey_final.
3583 Affected files are lib/silcclient/protocol.[ch] and
3584 lib/silcclient/client.[ch].
3586 * Removed the `hmac_key' and `hmac_key_len' fields from the
3587 SilcClientConnection structure; not needed. Affected file is
3588 lib/silcclient/client.h.
3592 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Do not ask whether user wants to use the negotiated private key
3595 for private messages, just use it. Affected file is
3596 silc/local_command.c.
3598 * Added `send_enc_key' and `enc_key_len' fields to the
3599 SilcIDListData structure since they are needed in the re-key
3600 phase. Affected file is silcd/idlist.[ch].
3602 * Implemented the simple re-key protocol into the server.
3603 Affected files silcd/server.c and silcd/protocol.[ch]. The
3604 re-key will be performed once in an hour, by default.
3606 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3607 Added silc_server_rekey, silc_server_rekey_callback and
3608 silc_server_rekey_final.
3610 * Removed Tunneled flag from the protocol. Updated the code
3611 and the specifications.
3613 * Adde `pfs' field to the SilcIDListData to indicate whether
3614 the PFS is to be performed in the re-key. Affected file is
3617 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3619 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3620 int64 of at least the xintXX size. If void * is less that 4
3621 bytes uint32 * will be used. Defined bool as boolean.
3623 * Changed _ALL_ unsigned long and unsigned int to uint32,
3624 unsgined short to uint16 in the source tree.
3626 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3627 not handle clients that has entry->data.registered == FALSE.
3628 They are not in the network anymore. Affected file is
3631 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Implemented the sending of the SERVER_SIGNOFF notify in the
3634 server. Affected file is silcd/server.c.
3636 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3637 Added also silc_notify_payload_encode_args into the
3638 lib/silccore/silcnotify.[ch].
3640 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3641 Affected file silcd/packet_receive.c.
3643 * Implemented the SERVER_SIGNOFF notify handling in the client
3644 library. Affected file lib/silcclient/client_notify.c. Also,
3645 implemnted the printing of the SERVER_SIGNOFF info to the
3646 application. Affected file silc/client_ops.c.
3648 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3649 if the deleting was successful. Affected file silcd/idlist.[ch].
3651 * Added support for public key authentication in the connection
3652 authentication protocol in the client library. Affected file
3653 lib/silcclient/protocol.c.
3655 * Changed the server's silc_idlist_get_clients_by_* interface
3656 to support already allocated array so that new entries may be
3657 added to pre-allocated array. Affected file silcd/idlist.[ch].
3658 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3659 and command replies.
3661 * All command reply functions in the server now calls the
3662 pending command callback even if error occured. This way the
3663 error will be delivered to the client as well. Affected files
3664 silcd/command.c and silcd/command_reply.c.
3666 * Fixed INFO command to return local server's info if no server
3667 was provided. Affected file lib/silcclient/command.c.
3669 * Removed RESTART command for good. Updated the code and the
3672 * Rewrote parts of the task system. It is a bit simpler now.
3673 Removed unsued task priorities. The affected files are
3674 lib/silcutil/silctask.[ch].
3676 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Moved the USERS printing from the library to the application.
3679 Affected files lib/silcclient/command.c and silc/client_ops.c.
3681 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * Added channel key re-key support. The re-key is perfomed
3686 only by the router and is done once in an hour. Added `rekey'
3687 field to the SilcChannelEntry in the server. Affected files
3688 silcd/server.c and silcd/idlist.h.
3690 * Added silc_task_unregister_by_context into the file
3691 lib/silcutil/silctask.[ch].
3693 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Added SILC_UMODE_GONE mode to indicate when the client is not
3696 present in the SILC network. Added also support to the local
3697 command AWAY that will set this mode. Added support of showing
3698 "xxx is gone" in WHOIS command. The USERS command shows the
3699 gone status as well.
3701 * Fixed setting server and router operator privileges in the
3702 server's UMODE command. Affected file silcd/command.c.
3704 * Merged the SKE KE1 and KE2 payloads into one payload. The
3705 new KE payload is equivalent to the old KE2 payload.
3707 Cleaned up the SKE Start Payload parsing. It now uses the
3708 simple buffer unformatting to do the parsing. A lot faster
3711 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3712 to the SKE that is used to indicate whether both of the SKE
3713 parties should perform authentication. By default only the
3714 responder performs authentication. By setting this flag also
3715 the initiator must do authentication. By default it is unset
3716 since in normal SKE case, client to server connection, only
3717 the responder should do authentication. When doing SKE between
3718 two clients both should perform authentication. Updated the
3719 code and the protocol specs.
3721 * A little fix to IDENTIFY command in the server. Search the
3722 client first by hash not nickname. Affected file is
3725 * Fixed the silc_client_close_connection to support closing
3726 the client to client connections wihtout deleting too much
3727 data. Affected file lib/silcclient/client.c.
3729 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3730 are received if protocol used to be active but is not anymore
3731 the application would crash due to NULL pointer dereference.
3732 Affected files silcd/server.c and lib/silcclient/client.c.
3734 * Added `hash' field to the SilcClientConnection to include
3735 the hash function negotiated in the SKE protocol.
3737 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3738 to set the channel founder authentication data. A client can
3739 claim the founder rights later by providing the authentication
3740 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3741 This way the channel founder can regain the channel founder
3742 privileges even it is left the channel. This works only on
3743 local server and the client must be connected to the same
3744 server to be able to regain the founder rights. Updated the
3745 protocol specs accordingly.
3747 Added support to the CMODE command in the client to set the
3748 founder auth data. Read the README to see how to set it.
3750 Added support to the CUMODE command to claim the founder
3751 rights. Read the README to see how to do it.
3753 Added support for the founder authentication to the Channel
3754 Entry in the server. Affected file silcd/idlist.h.
3756 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3757 server's CMODE command. Affected file silcd/command.c.
3759 * Added the following new functions into lib/silccore/silcauth.[ch]:
3760 silc_auth_get_method and silc_auth_get_data.
3762 * The server now saves the remote hosts public key to the
3763 SilcIDListData pointer. Affected file silcd/protocol.c.
3765 * The normal server now does not remove the channel entry from
3766 the cache if the founder authentication data is set. It used
3767 to remove it if the founder was the last one on the channel on
3768 the server and left the channel. The auth data is saved and
3769 if the channel is re-joined later the old entry is used with
3770 the old auth data. Affected files silcd/command_reply.c and
3773 * Removed the `pkcs' field from the SilcIDListData structure
3774 in the server; it is not used. Affected file silcd/idlist.h.
3776 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * Fixed packet processing on slow links. Partial packets were
3779 never re-processed because the incoming data buffer was cleared
3780 by the application. Application must not directly clear the
3781 sock->inbuf, the packet processing routines handle it. Fixed
3782 this in client library and in server.
3784 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * Fixed the WHOIS and IDENTIFY send reply function to really
3787 check whether to send list or just one entry. Affected file
3790 * Cleaned up the LEAVE command's channel key distribution. The
3791 affected file silcd/command.c.
3793 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3794 can enforce the channel mode as well. In that case the ID
3795 includes the ID of the server. The code now enforces the
3796 mode change if the router have different mode than the server.
3798 * The notify client operation with CMODE_CHANGE notify can now
3799 return NULL client_entry pointer if the CMODE was not changed
3800 by client. Application must check for this.
3802 * Added <Server ID> argument to INFO command to support server
3803 info fetching by Server ID.
3805 * Added silc_server_announce_get_channel_users to get assembled
3806 packets of channel users of the specified channel. Affected
3807 file silcd/server.[ch].
3809 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3810 was freed underneath the ID Cache.
3812 * Re-announce clients when the server received CHANNEL_CHANGE
3813 notify from the router. Affected file silcd/packet_send.c.
3815 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3818 crashed since it did not handle the fact that there is no cipher
3819 called "3" and didn't check the error condition. Now fixed.
3821 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3822 flag. It can be used to send message requests.
3824 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Implemented the RESTART command in the client.
3828 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3829 notice type messages. Added notice printing to the user
3832 * The channel keys are not re-generated if the channel's mode
3833 is PRIVKEY, ie private key on the channel exists. Affected
3834 files silcd/server.c and silcd/command.c.
3836 * Fixed a little bug in channel message delivery when channel
3837 private keys are set in the server. Affected file is
3838 silcd/packet_send.c.
3840 * Changed the setting on channel->on_channel = TRUE from the
3841 silc_client_save_channel_key to the JOIN command reply. The
3842 key payload is not received if the private channel key is set.
3843 Affected file lib/silcclient/command_reply.c and the
3844 lib/silcclient/client_channel.c.
3846 * When the CMODE_CHANGE notify is sent and the channel private
3847 key mode is removed the channel key must be re-generated in
3848 other cells as well. Added this support for the router in the
3849 silcd/packet_receive.c.
3851 * Added new local command NOTICE to send notice message on
3852 channel. Affected file silc/local_command.[ch].
3854 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Added new local command ME to the client. It is used to send
3857 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3858 some action. Affected file silc/local_command.[ch].
3860 * Changed channel_message and private_message client operations
3861 to deliver the message flags to the application. Added also
3862 the `flags' arguments to the silc_client_send_channel_message
3863 and silc_client_send_private_message functions. Affected file
3866 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * Redefined the Private Message Payload to support private message
3869 keys and to support the new private message flags. Updated
3870 the protocol specs. Flags makes it possible to have for example
3871 CTCP style messages.
3873 * Added new type SilcPrivateMessagePayload and defined an API
3874 for it in the lib/silcclient/silcprivate.[ch].
3876 * Tested private message private keys successfully. Tested the
3877 private message key set, unset and list commands with the new
3880 * Redefined the Channel Message Payload to include the channel
3881 message flags (equal with private message flags) to support
3882 for example CTCP style messages.
3884 * Defined some of the message (for channel and private message)
3885 flags. Updated the protocol specs and added the flags to the
3886 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3888 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Added SilcKeyAgreementStatus type to the key agreement routines
3891 to indicate the current status and error if one occured.
3892 The status types are defined in the lib/silcclient/silcapi.h.
3894 * Added new local command KEY that is used to set and unset private
3895 keys for channels, set and unset private keys for private messages
3896 with remote clients and to send key agreement requests and
3897 negotiate the key agreement protocol with remote client. The
3898 key agreement is supported only to negotiate private message keys,
3899 it currently cannot be used to negotiate private keys for channels,
3900 as it is not convenient for that purpose.
3902 * Fixed a minor pending callback setting bug in the function
3903 silc_client_get_client_by_id_resolve, now the function works.
3904 Affected file lib/silcclient/idlist.c.
3906 * Added function silc_net_get_local_port to get local bound
3907 port by socket. Added to lib/silcutil/silcnet.[ch].
3909 * Added `sockets' and `sockets_count' fields to the SilcClient
3910 object. They hold the sockets of the listenning sockets in
3911 the client. Listenning sockets may be for example the key
3912 agreement server. Affected file lib/silcclient/client.[ch].
3913 Added functions the silc_client_add_socket and the
3914 silc_client_del_socket. They are exported to the application
3917 * Added ~./silc/clientkeys to support other client's public keys.
3919 * Renamed verify_server_key client operation to verify_public_key
3920 and added one argument to indicate the type of the connection
3921 (server, client etc.).
3923 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Added silc_server_connection_auth_request to handle the
3926 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3927 silcd/packet_receive.[ch].
3929 * Added silc_server_send_connection_auth_request into the
3930 silcd/packet_send.c to send the connection auth request packet.
3932 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3935 * Fixed the public key authentication in responder side in the
3936 server. The `auth_data' pointer includes the SilcPublicKey
3937 not the path to the public key. Affected file silcd/protocol.c.
3939 * Implemented the public key authentication in the initiator side
3940 in the server. Affected file silcd/protocol.c.
3942 * Removed the [RedirectClient] config section from the server
3943 configuration. Is not needed and I don't want to implement it.
3945 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Cleaned up the CMODE command in the server. It now works
3948 correctly and supports all the modes defined in the protocol.
3949 Affected file is silcd/command.c.
3951 * Added `hmac_name' field to the SilcChannelEntry in the server
3952 to hold the default HMAC of the channel. It can be set when
3953 creating the channel (with JOIN command). Affected files
3956 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3957 type to indicate the change of the current cipher and hmac
3958 on the channel. Client can safely ignore the <cipher> argument
3959 (if it chooses to do so) since the CHANNEL_KEY packet will
3960 force the channel key change anyway. The <hmac> argument is
3961 important since the client is responsible of setting the new
3962 HMAC and the hmac key into use.
3964 * Fixed the CMODE command in the client library as well.
3966 * Tested CMODE command in router environment successfully.
3968 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Show the version of the remote client (or server) when connecting
3971 to the server. It is logged to the log file. Affected file
3972 is silcd/protocol.c.
3974 * Fixed the KILLED notify handling in the client library. The
3975 client must be removed from all channels when receiving the
3978 Also, do not remove the client entry when giving the KILL
3979 command but when the KILLED notify is received.
3981 * Removed silc_idlist_find_client_by_nickname from the server.
3982 Not needed anymore. Affected files silcd/idlist.[ch].
3984 * Implemented the CHANNEL_CHANGE notify type handling to the
3985 server. Affected file silcd/server.c.
3989 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Added silc_server_send_notify_invite to send the INVITE
3992 notify between routers.
3994 * Implemented the INVITE command correctly to the server.
3996 * Implemented the INVITE notify type handling in the server.
3998 * Implemented the INVITE command to the client library and on the
4001 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Added function silc_server_get_client_resolve to find the
4004 client entry by ID from all ID lists and then resolve it
4005 (using WHOIS) if it cannot be found. Affected file is
4008 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4010 * Implemented the BAN command to the client library.
4012 * The JOIN command in the server now checks the invite list
4015 * Changed the silc_command_reply_payload_encode_va and the
4016 silc_command_payload_encode_va to support that if argument is
4017 NULL it ignores and checks the next argument. Affected file
4018 lib/silccore/silccommand.c.
4020 * Added silc_server_send_notify_ban to send the BAN notify
4021 type between routers.
4023 * Chaned the silc_notify_payload_encode to support that if
4024 argument is NULL it ignores and checks the next argument.
4025 Affected file lib/silccore/silcnotify.c.
4027 * Tested ban lists in router environment successfully.
4029 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * Implemented BAN command to the server, in silcd/command.[ch].
4033 * Removed the BAN and INVITE_LIST modes from the CMODE command
4036 * Added function silc_string_match to regex match two strings.
4037 Affected files lib/silcutil/silcutil.[ch].
4039 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4041 * Redefined parts of the SilcChannelEntry in the server to support
4042 the new ban and invite lists.
4044 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Redefined the INVITE command. The same command can be used to
4047 invite individuals to the channel but also to manage the invite
4048 list of the channel (to add to and remove from the invite list).
4049 Updated the protocol specs.
4051 * Added new command SILC_COMMAND_BAN that can be used to manage
4052 the ban list of the channel. Updated the protocol specs.
4054 * Removed the channel modes: the SILC_CMODE_BAN and the
4055 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4056 in the CMODE command. The equivalent features are now available
4057 using INVITE and BAN commands. Updated the protocol specs.
4059 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4060 in the network about change in the current ban list. The notify
4061 type is not used by the client.
4063 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4064 support the invite lists.
4066 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Added new function silc_string_regexify that converts string
4069 including wildcard characters into regex string that can
4070 be used by the GNU regex library. Added into the file
4071 lib/silcutil/silcutil.[ch].
4073 Added silc_string_regex_combine to combine to regex strings
4074 into one so that they can be used as one regex string by
4075 the GNU regex library. Added into the file
4076 lib/silcutil/silcutil.[ch].
4078 Added silc_string_regex_match to match two strings. It returns
4079 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4081 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4083 * Imported GNU regex to the soruce tree into lib/contrib.
4084 Fixed some compiler warning from the regex.c.
4086 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Fixed MOTD command in the server to work in router environment.
4090 * Fixed the MOTD command in the client library to support
4091 the server argument in the command.
4093 * Added `nickname_len' argument to the silc_idlist_add_client
4094 in the server, as the `nickname' argument may be binary data
4097 * Added silc_idlist_get_channels to return all channels from
4100 * Implemented LIST command to the server. Affected file is
4103 * Implemented the LIST command to the client library and on the
4106 * Added [<user count>] argument to the LIST command reply.
4107 With private channels the user count is not shown.
4109 * Updated TODO and README.
4111 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * The client entry's data.registered must be TRUE even with
4114 global client entry on global client list. The data.registered
4115 is used to check whether the client is anymore in the network,
4116 for example with WHOWAS command so it must be valid.
4118 * Fixed the WHOWAS command in the server. It now actually works
4119 in router environment. Added function into silcd/command_reply.c
4120 silc_server_command_reply_whowas_save.
4122 * Added silc_idlist_purge function to the silcd/idlist.c
4123 to periodically purge the ID Cache.
4125 * Fixed INFO command in the server. It works now in router
4126 environment. Added <server name> argument to the INFO command
4127 reply. Updated the protocol specs.
4129 * Fixed minor bug in silc_idcache_purge to not purge if the
4130 expire value is zero.
4132 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4133 they were buggy because of the WHOWAS information.
4135 * Fixed local command MSG to handle the async resolving of
4136 the remote client properly. It used to fail the first MSG.
4137 Affected file silc/local_command.c.
4139 * Added `data_len' field to SilcIDCache context.
4141 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Update TODO. Todo in commands in the server.
4145 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4148 used by routers as broadcast packet to inform other routers
4149 about the changed user mode.
4151 Implemented the notify handling in the server. Affected file is
4152 silcd/packet_receive.c. Added the function
4153 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4155 * Added new generic Channel Payload and deprecated the New Channel
4156 Payload. The New Channel Payload is now the generic Channel
4159 * Added new argument `mode' to the silc_server_send_new_channel
4160 as it is required in the Channel Payload now.
4162 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4163 and created a new and real SilChannelPayload to represent the
4164 new generic Channel Payload. Implemented the encode/decode
4165 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4167 * Added silc_server_get_client_channel_list to return the list
4168 of channels the client has joined for WHOIS command reply.
4169 Affected file silcd/server.[ch].
4171 * Implemented the channel list sending in the WHOIS command reply
4172 in server and in the client.
4174 Implemented the channel list displaying on the user interface
4175 as well. Affected file silc/client_ops.c.
4177 * Added silc_channel_payload_parse_list to parse list of Channel
4178 Payloads. It returns SilcDList list of SilcChannelPayloads.
4179 Client for example can use this function to parse the list of
4180 channels it receives in the WHOIS command reply. The caller
4181 must free the list by calling silc_channel_payload_list_free.
4182 Affected files lib/silccore/silcchannel.[ch].
4184 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Added one new argument <user mode> to the WHOIS command reply
4187 to return the mode of the user in SILC. Updated the protocol
4190 Implemented it to the server and client.
4192 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Fixed the mode printing on the user interface on joining.
4195 Affected file silc/client_ops.c.
4197 * Implemented the UMODE command and user modes in general to the
4198 client library and to the user interface.
4200 * Implemented the UMODE command to the server.
4202 * The server now sends UNKNOWN_COMMAND error status if client sends
4203 unknown command. Affected file silcd/command.c.
4205 * All server commands now handle the command identifier the right
4206 way when sending the command reply to the client. The client can
4207 use to identify the command replies with the identifier.
4209 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4211 * Added silc_server_get_client_route to resolve the route to
4212 the client indicated by the client ID. Affected file is
4215 * Added silc_server_relay_packet as general function to relay
4216 packet to arbitrary destination. This deprecates functions
4217 like _send_private_message_key, _relay_notify etc. Affected
4218 file is silcd/packet_send.[ch].
4220 Removed silc_server_send_key_agreement,
4221 silc_server_send_private_message_key and
4222 silc_server_packet_relay_notify functions from the file
4223 silcd/packet_send.[ch].
4227 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4228 server. Affected file silcd/packet_receive.[ch].
4230 * Implemented the KILL command to the client. Implemented the
4231 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4232 Affected files lib/silcclient/command[_reply].c and
4233 lib/silcclient/client_notify.c. Implemented the KILL notify
4234 printing in the user inteface.
4236 * Fixed a lot silc_parse_nick memory leaks from the client
4237 library in the file lib/silcclient/command.c.
4239 * Changed the silc_server_send_notify_on_channels's `sender'
4240 argument from SilcSocketConnection to SilcClientEntry to
4241 check the sender as entry and not as connection object and not
4242 to send to the client provided as argument. The affected file
4243 is silcd/packet_send.[ch].
4245 * The notify packets that are destined directly to the client used
4246 to not to be processed by the server. Now changed that and the
4247 server processes all notify packets. After relaying the packet
4248 to the client the notify packet is processed in the server.
4250 * The silc_server_free_client_data now checks whether there is
4251 pending outgoing traffic for the client and purges the data to
4252 the network before removing the client entry.
4254 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4257 an client is killed from the SILC Network. Updated the protocol
4260 Added new function silc_server_send_notify_killed to the
4261 silcd/packet_send.[ch].
4263 * Added function silc_server_packet_relay_notify to relay notify
4264 packets that are destined directly to a client. In this case
4265 the server does not process the notify packets but merely relays
4266 it to the client. Affected file silcd/packet_send.[ch].
4268 Added also silc_server_packet_process_relay_notify to check
4269 whereto relay the notify. Affected file is
4270 silcd/packet_receive.[ch].
4272 * Implemented the KILL command to the server.
4276 * Added the backup schema desgined last fall to the protocol
4277 specs for everyone to see. The specification is in the
4278 *-spec-xx.txt draft and the packet type definitions for the
4279 backup routers is in *-pp-xx.txt draft. Thusly, added also
4280 new packet type SILC_PACKET_CELL_ROUTERS.
4282 * A big security problem in the implementation discovered. The
4283 signoff of an client did not cause new channel key generation
4284 which it of course should've done. The channel keys must be
4285 always re-generated when client leaves (or signoffs) the channel.
4286 The silc_server_remove_from_channels funtion now handles
4287 the channel key re-generation.
4289 * Added `sender' argument to the silc_server_send_notify_on_channels
4290 to not to send the client provided as argument. Affected file
4291 silcd/packet_send.[ch].
4293 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Implemented OPER and SILCOPER commands into the server and
4298 * Added silc_auth_verify and silc_auth_verify_data to verify
4299 the authentication directly from the authentication payload.
4300 It supports verifying both passphrase and public key based
4301 authentication. Affected file lib/silccore/silcauth.[ch].
4303 * Added `hash' field to the SilcIDListData structure. It is the
4304 hash negotiated in the SKE protocol. Affected file is
4307 * Slight redesigning of the SilcAuthPayload handling routines.
4308 Do not send SilcPKCS but SilcPublicKey as argument.
4310 * Implemented the public key authentication support to the
4311 serverconfig. The public key is loaded from the provided path
4312 and saved as authentication data to void * pointer. Thus,
4313 changed the unsigned char *auth_data to void *auth_data;
4315 * Fixed SHUTDOWN command to send the reply before the server
4316 is shutdown. :) Affected file silcd/command.c.
4318 * Fixed fatal bug in CONNECT command. The hostname was invalid
4319 memory and server crashed. Affected file silcd/command.c.
4321 * Fixed fatal bug in CLOSE command. The server_entry became
4322 invalid but was referenced later in the command. Affected file
4325 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Fixed fatal bug in failure packet handling. Server ignored
4328 the failure and thus crashed when it came.
4332 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4335 that the command may be executed only once in (about) 2 seconds.
4336 The old SILC_CF_LAG flag is same but allows command bursts up
4337 to five before limiting.
4339 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4340 server code. Various commands now includes the CF_LAG_STRICT
4341 flag to disallow any kind of miss-use of the command.
4343 * Fixed the silc_buffer_unformat to not to allocate any data
4344 if the length of the data is zero. It used to allocate the
4345 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4347 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * Changed the format of AdminConnection configuration section
4350 in the server. Added username of the admin to the format.
4351 Affected files silcd/serverconfig.[ch].
4353 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4354 to return admin configuration data by host, username and/or
4357 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4359 * Implemented WHOWAS command to the server. Added the functions:
4361 silc_server_command_whowas_parse,
4362 silc_server_command_whowas_send_reply,
4363 silc_server_command_whowas_from_client and
4364 silc_server_command_whowas_from_server
4366 * Added <Client ID> argument to the WHOWAS command reply. Updated
4367 the protocol specs accordingly.
4369 * Implemented WHOWAS command and command_reply to the client
4372 Implemented the WHOWAS printing on the user interface.
4374 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * Added new argument to the WHOWAS command reply, the real name.
4377 It is an optional argument. Updated the protocol specs.
4379 * Added SilcIDCacheDestructor callback that is registered when
4380 the SilcIDCache is allocated. The callback is called when
4381 an cache entry in the ID Cache expires, or is purged from the
4382 cache. Added into lib/silccore/idcache.[ch].
4384 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4385 to destruct the client entries when the cache entry expires.
4386 Other ID Cache's in server and in the client library ignores
4389 * If the ID Cache entry's `expire' field is zero then the entry
4390 never expires. Added boolean `expire' argument to the
4391 silc_idcache_add function in the lib/silccore/idcache.[ch].
4392 If it is TRUE the default expiry value is used.
4394 * Added silc_server_free_client_data_timeout that is registered
4395 when client disconnects. By default for 5 minutes we preserve
4396 the client entry for history - for WHOWAS command.
4398 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4400 * Added support to the server to enforce that commands are not
4401 executed more than once in 2 seconds. If server receives
4402 commands from client more frequently, timeout is registered
4403 to process the commands. Affected file silcd/command.c.
4404 Added new function silc_server_command_process_timeout.
4406 * Changed NICK_NOTIFY handling in client library to check that
4407 if the client's nickname was changed, so there is no need to
4408 resolve anything from the server.
4410 * Removed error printing from the WHOIS and IDENTIFY commands.
4411 If error occurs then it is ignored silently in the client library.
4412 The application, however, may map the received error to
4413 human readable error string. The application currently maps
4414 the NO_SUCH_NICKNAME error to string.
4416 * Made the command status message public to the application. Moved
4417 them from lib/silcclient/command_reply.c to
4418 lib/silcclient/command_reply.h. The application can map the
4419 received command status to the string with the
4420 silc_client_command_status_message function.
4422 * Added check to the server to check that client's ID is same
4423 as the Source ID in the packet the client sent. They must
4426 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Added dist-bzip hook to the Makefile.am to make bzip2
4429 compressed distributions.
4431 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Server now enforces the maximum length for the nickname and
4434 the channel as protocol specification dictates. 128 bytes for
4435 nickname and 256 bytes for channel name.
4437 * Moved the WHOIS printing to the application. The client libary
4438 does not print out the WHOIS information anymore, the application
4439 must do it. Renamed silc_client_command_reply_whois_print to
4440 the silc_client_command_reply_whois_save.
4442 The client's idle time is also sent to the application now, and
4443 the idle is shown on screen.
4445 * Added silc_client_command_reply_identify_save to save the
4446 received IDENTIFY entries.
4448 * Do not check for channel private keys in message sending and
4449 reception if the channel does not have the PRIVKEY mode set.
4450 Affected file lib/silclient/client_channel.c.
4452 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4455 just surfaced after chaning the JOIN procedure.
4457 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Added silc_client_get_clients_by_list to get client entries
4460 from Client ID list, that is returned for example by JOIN
4461 and USERS command replies. The application should use this
4462 function for example when JOIN command reply is received to
4463 resolve the clients already on the channel (library does not
4464 do that anymore as USERS command reply is not used in the JOIN
4465 procedure anymore). Affected files lib/silcclient/silcapi.h and
4466 lib/silcclient/idlist.c.
4468 * JOIN command reply and USERS command reply returns now SilcBuffer
4469 pointers instead of unsigned char pointers when returning
4470 the client list and mode list.
4472 * Added <Client ID> argument to the JOIN command reply, mainly
4473 for the server to identify for which client the command was
4474 originally sent. Updated protocol specs accordingly.
4476 * Added SilcDlist private_key pointer to the SilcChannelEntry
4477 in the client to support the channel private keys. Affected
4478 file is lib/silcclient/idlist.h.
4480 * Added SilcChannelPrivateKey argument to the function
4481 silc_client_send_channel_message so that application can choose
4482 to use specific private ke if it wants to. If it is not provided,
4483 the normal channel key is used, unless private keys are set.
4484 In this case the first (key that was added first) is used
4485 as the encryption key.
4487 * Implemented the support for channel private key handling.
4488 Implemented the following functions:
4490 silc_client_add_channel_private_key,
4491 silc_client_del_channel_private_keys,
4492 silc_client_del_channel_private_key,
4493 silc_client_list_channel_private_keys and
4494 silc_client_free_channel_private_keys
4496 Affected file lib/silcclient/client_channel.c.
4498 * Added the support for the private keys in the channel message
4499 sending and encryption and in the message reception and
4500 decryption. Affected funtions are
4501 silc_client_send_channel_message and silc_client_channel_message.
4503 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Added SKE's key verify callback to the client library's
4506 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4508 * Removed the statement that server (or router) must send USERS
4509 command reply when joining to the channel so that the client
4510 knows who are on the channel. Instead, the client list and
4511 client's mode list is now sent in the JOIN command reply to the
4512 client who joined channel. This is better solution.
4514 * Added function silc_server_get_users_on_channel and function
4515 silc_server_save_users_on_channel to the silcd/server.[ch].
4517 * Removed function silc_server_command_send_users from the
4520 * Do not show topic on the client library anymore. The topic is
4521 sent in the command reply notify to the application and the
4522 application must show the topic now.
4524 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Added client searching by nickname hash into the IDENTIFY and
4527 WHOIS commands in the server as they were clearly missing from
4528 them. Affected file is silcd/command.c.
4530 * Fixed a bug in private message receiving in the client library.
4531 The remote ID was freed and it wasn't supposed, now it is
4534 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Minor fix to the channel payload; allocate the data area, as it
4537 needs to be of specific length.
4539 * If the key agreement port is zero then the operating
4540 system will define the bound port. Affected files are
4541 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4543 * Added new function silc_channel_payload_decrypt into the file
4544 lib/silccore/silcchannel.[ch].
4546 * Moved the channel message etc, check from silc_packet_decrypt
4547 to applications. The library calls now a generic
4548 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4549 when the packet is either normal or special. This was done to
4550 allow more wide range of checking that was not allowed when
4551 the code was in library. Now applications can do virtually any
4552 checks to the packet and return to the library the decision how
4553 the packet should be processed. Affected files are
4554 lib/silccore/silcpacket.[ch].
4556 Added silc_server_packet_decrypt_check to the server and
4557 silc_client_packet_decrypt_check to the client library.
4559 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4560 to send with specified source and destination information.
4562 * Channel message delivery between routers was broken after the
4563 channel key distribution was fixed earlier. The channel key
4564 was used be to distributed to other routers as well which is not
4565 allowed by the protocol. Now this is fixed and channel keys
4566 really are cell specific and the channel message delivery between
4567 routers comply with the protocol specification.
4569 * Fixed various commands in server to check also the global list
4570 for the channel entry and not just the local list. The affected
4571 file silcd/command.c.
4573 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added assert()s to buffer formatting and unformatting routines
4576 to assert (if --enable-debug) when error occurs. Affected
4577 file: lib/silcutil/silcbuffmt.c.
4579 * Changed to auto-reconnect to check whether the remote host is
4580 router and register the re-connect timeout if it is. It used
4581 to check that whether we are normal server, but router must do
4582 auto-reconnect with another router as well. Affected file
4585 * Removed the [<key len>] option from CMODE command as the cipher
4586 name decides the key length, nowadays. See the defined ciphers
4587 from the protocol specification.
4589 * Added [<hmac>] option to the CMODE command to define the HMAC
4590 for the channel. Added SILC_CMODE_HMAC channel mode.
4592 * Added [<hmac>] option for the JOIN command so that user can
4593 select which HMAC is used to compute the MACs of the channel
4596 * Added Hmac field to the Channel Message Payload. The integrity
4597 of plaintext channel messages are now protected by computing
4598 MAC of the message and attaching the MAC to the payload. The
4599 MAC is encrypted. Now, it is clear that this causes some
4600 overhead to the size of the packet but rationale for this is that
4601 now the receiver can verify whether the channel message decrypted
4602 correctly and also when private keys are set for the channel the
4603 receiver can decrypt the packet with several keys and check from
4604 the MAC which key decrypted the message correctly.
4606 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4607 lib/silccrypt/silccipher.[ch].
4609 * Added silc_hash_len to return the digest length into the
4610 lib/silcrypt/silchash.[ch].
4612 * Rewrote parts of Silc Channel Payload interface in the
4613 lib/silccore/silcchannel.[ch]. The encode function now also
4614 encrypts the packet and parse function decrypts it.
4616 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Fixed a minor formatting bug in the SKE's key material processing.
4619 It actually might have processed the keys wrong way resulting
4622 * Redefined the mandatory HMAC algorithms and added new algorithms.
4623 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4624 and hmac-md5 truncated to 96 bits. The mandatory is now
4625 hmac-sha1-96. Rest are optional (including the one that used
4626 to be mandatory). Rationale for this is that the truncated HMAC
4627 length is sufficient from security point of view and can actually
4628 make the attack against the HMAC harder. Also, the truncated
4629 HMAC causes less overhead to the packets. See the RFC2104 for
4632 * Added new [hmac] configuration section. The SKE used to use
4633 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4634 is of course wrong. The official names that must be proposed in
4635 the SKE are the ones defined in the protocol specification
4636 (hmac-sha1-96 for example). The user can configure any hmac
4637 using any hash function configured in the [hash] section. At
4638 least, the mandatory must be configured.
4640 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4642 * Added HMAC list to the SKE proposal list. It has now both
4643 hash algorithm list and HMAC list. This makes the protocol
4644 incompatible with previous versions. The SKE now seems to work
4645 the way it is supposed to work, for the first time actually.
4647 * Defined plain Hash algorithms to the protocol specification.
4650 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Implemented support for key agreement packets into the server.
4653 Added functions silc_server_key_agreement and
4654 silc_server_send_key_agreement. Other than these functions,
4655 server has nothing to do with this packet.
4657 * Added support for private message key packets into the server.
4658 Added functions silc_server_private_message_key and
4659 silc_server_send_private_message_key.
4663 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4664 called in the protocol's final callback instead in the END
4665 protocol state. This makes a little more sense and in the same
4666 time in client we can use the same protocol routines for normal
4667 key exchange and to key agreement packet handling as well.
4669 * Added to both client's and server's KE protocol context the
4670 SilcSKEKeyMaterial pointer to save the key material. We will
4671 bring the key material to the protocol's final callback by doing
4672 this. The final callback must free the key material.
4674 * Added SKE's packet_send callback into client's KE protocol
4675 context so that the caller can choose what packet sending function
4676 is used. This way we can use different packet sending when
4677 doing normal SKE when doing key agreement packet handling (in
4678 the key agreement packet handling we do not want to encrypt
4681 * Implemented the responder side of the key agreement routines
4682 in the client. The client can now bind to specified port and
4683 accept incoming key negotiation. The key material is passed
4684 to the application after the protocol is over.
4686 * Implemented the processing of incoming Key Agreement packet
4687 in the client. Added function silc_client_key_agreement to
4690 * Implemented the intiator side of the key agreement routines
4691 in the client. The client can now initiate key agreement with
4692 another remote client. The key material is passed to the
4693 application after the protocol is over.
4695 * Created client_keyagr.c to include all the key agreement
4698 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4699 SILC_TASK_CALLBACK except that it is not static.
4701 * Created client_notify.c and moved the Notify packet handling
4702 from the client.[ch] into that file.
4704 * Created client_prvmsg.c and moved all private message and
4705 private message key routines from the client.[ch] into that file.
4707 * Create client_channel.c and moved all channel message and
4708 channel private key routines from the client.[ch] into that file.
4710 * Changed silc_client_get_client_by_id_resolve to resolve with
4711 WHOIS command instead of IDENTIFY command, in the file
4712 lib/silclient/idlist.c.
4714 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Implemented the SKE's responder side to the Client library.
4718 * When FAILURE is received to the protocol do not trust it
4719 blindly. Register a timeout to wait whether the remote closes
4720 the connection as it should do it, only after that process the
4721 actual failure. This was changed to both client and server.
4723 * Added client_internal.h to include some of the structures
4724 there instead of client.h in lib/silcclient/.
4726 * Added function silc_task_unregister_by_callback to unregister
4727 timeouts by the callback function.
4729 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Some "Incomplete WHOIS info" errors has been appearing on the
4732 log files. Took away the entry->userinfo check from WHOIS
4733 reply sending. The entry->userinfo is now " " if client did not
4734 provide one. I thought this was fixed earlier but something
4735 is wrong still. Let's see if the error still appears.
4737 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * Fixed a minor bug in the login when the channel key is
4740 re-generated in the server. It used to generate the key in
4741 wrong order and thus caused problems in the channel traffic.
4743 * Fixed a minor bug in channel key distsribution after
4744 KICK command. The key was not sent to the router even though
4747 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4749 * Added silc_ske_process_key_material_data as generic routine
4750 to process any key material as the SILC protocol dictates. The
4751 function is used by the actual SKE library but can be used by
4752 applications as well. This relates to the private message keys
4753 and the channel private keys since they must be processed the
4754 same way the normal SILC session keys. The protocol dictates
4755 this. Affected files: lib/silcske/silcske.[ch].
4757 Added also silc_ske_free_key_material to free the
4758 SilcSKEKeyMaterial structure.
4760 * Defined silc_cipher_set_key function to set the key for
4761 cipher without using the object's method function. The affected
4762 files: lib/silccrypt/silccipher.[ch].
4764 * Implemented silc silc_client_add_private_message_key,
4765 silc_client_add_private_message_key_ske,
4766 silc_client_del_private_message_key,
4767 silc_client_list_private_message_keys and
4768 silc_client_free_private_message_keys functions in the
4771 Added functions silc_client_send_private_message_key to send
4772 the Private Message Key payload and silc_client_private_message_key
4773 to handle incoming Private Message Key payload.
4775 * Added Cipher field to the Private Message Key payload to set
4776 the cipher to be used. If ignored, the default cipher defined
4777 in the SILC protocol (aes-256-cbc) is used.
4779 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Removed lib/silcclient/ops.h file.
4783 Redefined parts of the SILC Client Library API. Created new
4784 file silcapi.h that deprecates the ops.h file and defines the
4785 published Client Library API. Defined also private message key
4786 API and channel private key API into the file.
4788 This is the file that the application must include from the
4789 SILC Client Library. Other files need not be included by
4790 the application anymore.
4792 * Added new key_agreement client operation callback and also
4793 defined the Key Agreement library API for the application.
4795 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4798 is used by clients to request key negotiation between another
4799 client in the SILC network. If the negotiation is started it
4800 is performed using the SKE protocol. The result of the
4801 negotiation, the secret key material, can be used for example
4802 as private message key.
4804 Implemented the Key Agreement payload into the files
4805 lib/silccore/silauth.[ch].
4807 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Redefined ciphers for the SILC protocol. Added some new ciphers
4810 and defined the key lengths for the algorithms. Changed the
4811 code accordingly. The default key length is now 256 bits.
4813 * Fixed SKE key distribution function silc_ske_process_key_material
4814 when the key length is more than 128 bits. The default key
4815 length in SILC is now 256 bits.
4817 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4818 to indicate unsupported algorithm.
4820 * Renamed rijndael.c to aes.c and all functions as well.
4822 * Fixed a long standing channel key setting bug in client library.
4823 Weird that it has never surfaced before.
4825 * Fixed bug in channel deletion. If the entire channel is removed
4826 then it must also delete the references of the channel entry
4827 from the client's channel list as the client's channel entry and
4828 the channel's client entry share same memory.
4830 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Implemented CONNECT and SHUTDOWN commands in the client.
4834 * Implemented CLOSE command to the client.
4836 * Added the function silc_idlist_find_server_by_name into the
4837 files silcd/idlist.[ch].
4839 Added the function silc_idlist_find_server_by_conn into the
4840 files silcd/idlist.[ch].
4842 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * DIE command was renamed to SHUTDOWN. Updated the both code
4847 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4848 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4850 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4853 * Added function silc_server_create_connection function to create
4854 connection to remote router. My server implementation actually
4855 does not allow router to connect to normal server (it expects
4856 that normal server always initiates the connection to the router)
4857 so the CONNECT command is only good for connecting to another
4860 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4863 or some other client was kicked from the channel.
4865 Implemented the handling of the notify type to both client
4868 Implemented silc_server_send_notify_kicked to send the KICKED
4869 notify. It is used to send it to the server's primary router.
4871 * Implemented the KICK command into server and client.
4873 * Added `query' argument to the silc_idlist_get_client function
4874 to indicate whether to query the client from server or not if
4877 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4878 to indicate that the client is not channel founder.
4882 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Removed the rng context from SilcPacketContext structure and
4885 changed that the packet routine uses the Global RNG API.
4887 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Added support for quit message that client can "leave" on the
4890 channel when it quits the SILC. It is ditributed inside the
4891 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4893 Added silc_server_free_client_data that will take the
4894 signoff message as argument.
4896 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4898 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Updated parts of the protocol specification to keep it up
4903 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4905 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4906 payloads in one packet.
4908 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4909 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4910 use now the new List flag.
4912 * Also deprecated the following packet types: REPLACE_ID,
4913 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4915 * Added list support for Notify packet in server.
4917 * Added silc_server_send_notify_channel_change to send the
4918 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4919 the silc_server_send_replace_id.
4921 * Added silc_server_send_notify_nick_change to send the
4922 NICK_CHANGE notify type. Deprecates the function
4923 silc_server_send_replace_id.
4925 * Added silc_server_send_notify_join to send the JOIN notify type.
4926 Deprecates the function silc_server_send_new_channel_user.
4928 * Added silc_server_send_notify_leave to send LEAVE notify type.
4929 Deprecates the function silc_server_send_remove_channel_user.
4931 * Added silc_server_send_notify_cmode and
4932 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4933 types. Deprecates the silc_server_send_set_mode function.
4935 * Added SERVER_SIGNOFF notify type to indicate that server has
4936 quit. This means that all clients on the channel from that
4937 server will drop. This can be also used when netsplit happens.
4939 Deprecated REMOVE_ID packet type since it is not needed anymore
4942 Added silc_server_send_notify_server_signoff to send the
4943 SERVER_SIGNOFF notify type. Deprecates the function
4944 silc_server_send_remove_id.
4946 Added also silc_server_send_notify_signoff to send the
4947 SIGNOFF notify type.
4949 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4950 SILC protocol from this day on. Changed the protocol
4951 specification as well.
4953 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4954 notify type. It is used between routers to notify about
4955 topic changes on a channel.
4957 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4960 * Partly updated the protocol specification to comply with the
4961 changes now made. It is still though a bit outdated.
4963 * The JOIN notify type now takes one extra argument <Channel ID>.
4964 The packet used to be destined to the channel but now the
4965 JOIN type may be sent as list thus it is impossible to
4966 destine it to any specific channel. By adding this argument
4967 it is again possible.
4969 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Added CREDITS file. The CHANGES and CREDITS file will appear
4972 in the distribution as well.
4974 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4977 types in the server's silcd/packet_receive.c.
4979 * Implemented CMODE and CUMODE to work in router environment.
4981 * Fixed minor encoding and decoding buglet from the
4982 lib/silccore/silcmode.c.
4984 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4987 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4989 * Changed all SilcConfigServer* and silc_config_server* to
4990 SilcServerConfig* and silc_server_config*, respectively.
4993 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Associated the ID (client or server ID) to the Authentication
4996 Payload to avoid any possibility of forging. Updated the
4997 protocol specification and the code accordingly.
4999 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * The RSA key length is now save to the RsaKey context in the
5002 key generation process in lib/silccrypt/rsa.c. The key length
5003 is now used to figure out the maximum size of the block allowed
5004 to be encrypted/signed.
5006 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5007 is equivalent to the silc_mp_mp2bin but does not allocate any
5010 * Changed silc_mp_mp2bin API to take length argument. If it is
5011 non-zero then the buffer is allocated that large. If zero, then
5012 the size is approximated using silc_mp_sizeinbase, which however
5015 * Created Global RNG API which is global RNG that application can
5016 initialize. After initializing, any routine anywhere in the
5017 code (including library) can use RNG without allocating a new
5018 RNG object. This was done to allow this sort of use of the
5019 RNG in code that has no chance to allocate RNG object. All
5020 applications currently allocate this and many routines in the
5021 library use this. Affected file lib/silccrypt/silcrng.[ch].
5023 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5024 it to use the Global RNG API.
5026 * Defined Authentication Payload into protocol specification that
5027 is used during SILC session to authenticate entities. It is
5028 used for example by client to authenticate itself to the server
5029 to obtain server operator privileges.
5031 Implemented this payload into the lib/silccore/silcauth.[ch].
5032 Implemented also routines for public key based authentication
5033 as the new protocol specification dictates.
5035 Moved definitions of different authentication methods from
5036 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5038 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5039 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5040 silc_pkcs_verify_with_hash functions into the file
5041 lib/silccrypt/silcpkcs.[ch].
5043 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5045 * The client entry's userinfo pointer must be always valid.
5046 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5047 will fail since it requires the userinfo. Now, the userinfo
5048 is allocated as "" if actual userinfo does not exist. Actually,
5049 it must exist and it is totally Ok to drop client connections
5050 that does not announce the userinfo. However, we will make
5051 this workaround for now.
5053 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5054 to return the remote port by socket.
5056 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5059 SILC_SERVER_PENDING_EXEC and added an new macro
5060 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5061 data or when error occurs while processing the pending command.
5063 Added new argument `destructor' into silc_server_command_pending
5064 and to the SilcServerCommandPending object. This destructor is
5065 now called after calling the pending callback or if error occurs
5066 immediately. If error occurs the actual pending callback won't
5067 be called at all - only the destructor. The destructor may be
5068 NULL if destructor is not needed.
5070 All this applies for client library code as well. Similar
5071 changes were made there as well for the pending commands.
5073 In the client, the application must now allocate the
5074 SilcClientCommandContext with the silc_client_command_alloc
5077 * Added reference counter to the SilcServerCommandContext. Added
5078 function silc_server_command_alloc and silc_server_command_dup
5081 Same type of functions added to the client library for the same
5084 * Removed the cmd_ident from IDListData away since it is now
5085 global for all connections. It is the command identifier used
5086 in command sending and with pending commands. The affected file
5089 * Added reference counter to the SilcSocketConnection objecet to
5090 indicate the usage count of the object. The object won't be
5091 freed untill the reference counter hits zero. Currently only
5092 server uses this, and client ignores it. The client must be
5093 set to use this too later. The affected files are
5094 lib/silccore/silcsockconn.[ch]. Added also the function
5095 silc_socket_dup to increase the reference counter.
5097 This was mainly added because it is possible that the socket
5098 is removed underneath of pending command or other async
5099 operation. Now it won't be free'd and proper DISCONNECTING
5100 flags, etc. can be set to avoid sending data to connection that
5101 is not valid anymore.
5103 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5104 the connection. After that it sets SILC_SET_DISCONNECTED.
5105 It is, however, possible that the socket data is not still freed.
5106 The silc_server_packet_process now checks that data is not
5107 read or written to connection that is DISCONNECTED. The socket
5108 get's freed when the reference counter hits zero.
5110 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Changed the client operation API: channel_message operation's
5113 `sender' is now the client entry of the sender, not the nickname
5114 and the `channel' is the channel entry, not the channel name.
5116 In the private_message operation the `sender' is now also the
5117 client entry of the sender not the nickname.
5119 Affected file is lib/silcclient/ops.h and all applications
5120 using the client operations.
5122 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Moved the calling of ops->connect() from connect_to_server_final
5125 into receive_new_id functin since that is the point when the
5126 client is actually allowed to send traffic to network. The
5127 affected file is lib/silcclient/client.c.
5129 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5132 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5133 (if needs broadcasting) instead of broadcasting the packets one
5134 by one which would make a burst in the network traffic.
5136 * Added `broadcast' argument to the functions in silcd/server.[ch]
5137 silc_server_create_new_channel[_with_id] to indicate whether
5138 to send New Channel packet to primary router.
5140 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Added new function into the silcd/server.[ch] files:
5143 silc_server_create_new_channel_with_id to create new channel with
5144 already existing Channel ID.
5146 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5147 lib/silccore/silcpacket.h. This packet is used t send list of
5148 Set Mode payloads inside one packet. Server uses this to set
5149 the modes for the channels and clients on those channels, that it
5150 announced to the router when it connected to it. The protocol
5151 specification has been updated accordingly.
5153 * The silc_server_new_channel did not handle the packet coming
5154 from normal server as it normally does not send that. However,
5155 when it announces its channels it does send it. Implemented
5156 the support for that.
5158 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5159 into the file lib/silccore/id.h.
5161 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Fixed memory leaks in the functions silc_idlist_del_client,
5164 silc_idlist_del_channel and silc_idlist_del_server in the file
5165 silcd/idlist.c. All of those leaked like a sieve.
5167 * Fixed some small memory leaks in the client's function
5168 silc_client_notify_by_server.
5170 * Added functions into silcd/server.c: silc_server_announce_clients,
5171 silc_server_announce_channels and silc_server_announce_server.
5172 These functions are used by normal and router server to announce
5173 to its primary router about clients, channels and servers (when
5174 router) that we own. This is done after we've connected to the
5177 These functions effectively implements the following packet types:
5178 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5179 and SILC_PACKET_NEW_ID_LIST.
5181 * Added new functions into the silcd/packet_receive.[ch]:
5182 silc_server_new_id_list, silc_server_new_channel_list and
5183 silc_server_new_channel_user_list to handle the incoming
5184 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5186 * Added support of changing Channel ID in the function
5187 silc_server_replace_id. If the server that announces a channel
5188 to the router already exists in the router (with same name but
5189 with different Channel ID), router is responsible to send
5190 Replace ID packet to the server and force the server to change
5191 the Channel ID to the one router has.
5193 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5194 client that the Channel ID has been changed by the router. The
5195 normal server sends this to the client. Client must start using
5196 the new Channel ID as the channel's ID.
5198 Implemented handling of this new type into lib/silcclient/client.c
5199 into the function silc_client_notify_by_server.
5201 * Added new function silc_idlist_replace_channel_id into the files
5202 silcd/idlist.[ch] to replace the Channel ID.
5204 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * Call silc_server_command_identify_check always when processing
5207 the IDENTIFY command in silcd/command.c
5209 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5212 send keepalive packets. The packet can be sent by clients,
5213 servers and routers.
5215 Added function silc_socket_set_heartbeat into the file
5216 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5217 If not set, the heartbeat is not performed. The actual
5218 heartbeat is implemented in the low level socket connection
5219 library. However, application is responsible of actually
5222 Added silc_server_send_heartbeat to send the actual heartbeat
5223 packet into silcd/packet_send.[ch]. Server now performs
5224 keepalive with all connections.
5226 * Added silc_task_get_first function into lib/silcutil/silctask.c
5227 to return the timeout task with shortest timeout. There was a bug
5228 in task unregistration that caused problems. TODO has been
5229 updated to include that task system must be rewritten.
5231 * The client library will now resolve the client information when
5232 receiving JOIN notify from server for client that we know but
5233 have incomplete information.
5235 * Rewrote parts of silc_server_remove_from_channels and
5236 silc_server_remove_from_one_channel as they did not remove the
5237 channel in some circumstances even though they should've.
5239 * Encryption problem encountered in server:
5241 The LEAVE command used to send the Channel Key packet to the
5242 router immediately after generating it. However, the code
5243 had earlier sent Remove Channel user packet but not immediately,
5244 ie. it was put to queue. The order of packets in the router
5245 was that Channel Key packet was first and Remove Channel User
5246 packet was second, even though they were encrypted in the
5247 reverse order. For this reason, MAC check failed. Now, this
5248 is fixed by not sending the Channel Key packet immediately but
5249 putting it to queue. However, this is more fundamental problem:
5250 packets that are in queue should actually not be encrypted
5251 because packets that are sent immediately gets encrypted
5252 actually with wrong IV (and thus MAC check fails). So, packets
5253 that are in queue should be encrypted when they are sent to
5254 the wire and not when they put to the queue.
5256 However, the problem is that the current system has not been
5257 designed to work that way. Instead, the packet is encrypted
5258 as soon as possible and left to the queue. The queue is then
5259 just purged into wire. There won't be any fixes for this
5260 any time soon. So, the current semantic for packet sending
5263 o If you send packet to remote host and do not force the send
5264 (the packet will be in queue) then all subsequent packets to the
5265 same remote host must also be put to the queue. Only after the
5266 queue has been purged is it safe again to force the packet
5269 o If you send all packets immediately then it safe to send
5270 any of subsequent packets through the queue, however, after
5271 the first packet is put to queue then any subsequent packets
5272 must also be put to the queue.
5274 Follow these rules and everything works fine.
5276 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Added new function silc_server_remove_clients_by_server to
5279 remove all client entries from ID list when the server connection
5280 is lost. In this case it is also important to invalidate all
5281 client entires as they hold the invalid server entry. This
5282 fixes fatal bug when server has lost connection and will reconnect
5285 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * Made some sanity checks to silc_server_daemonise like to check
5288 whether the requested user and group actually exists.
5290 * Added sanity check to SKE's silc_ske_responder_finish to check
5291 that the public and private key actually is valid.
5293 * Invalidate the client's nickname when receiving Replace ID
5294 packet and the Client ID is being replaced. This means that the
5295 server will query the nickname if someone needs it (client)
5298 * Sort the ID Cache in client library when the ID Cache data
5299 has changed (needs sorting).
5301 * Do not allow for SILC client to create several connections to
5302 several servers. The client does not support windows right now
5303 and generating multiple connections causes weird behaviour.
5305 Irssi-silc client does support windows and can handle several
5306 connections without problems, see: www.irssi.org and SILC plugin.
5308 * Fixed some places where client was added to the IDList. The
5309 rule of thumb is following (in order to get everything right):
5310 If the client is directly connected local client then the
5311 `connection' argument must be set and `router' argument must be
5312 NULL to silc_idlist_add_client function. If the client is not
5313 directly connected client then the `router' argument must
5314 bet set and the `connection' argument must be NULL to the
5315 silc_idlist_add_client function.
5317 * The funtion silc_server_packet_send_local_channel actually did
5318 not check whether the client was locally connected or not. It
5319 does that now. Fixed a bug related to LEAVE command.
5321 * Fixed Remove Channel User payload parsing bug in server's
5322 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5324 * The server's silc_server_save_channel_key now checks also the
5325 global ID list for the channel as it might not be in the local
5326 list. Fixed a bug related to LEAVE command.
5328 * Is this the end of the [<unknown>] buglet that has been lurking
5329 around for a long time? A little for loop fix in server's
5330 silc_server_command_whois_parse that is used by both IDENTIFY
5331 and WHOIS command. At least, this was a clear bug and a cause
5332 of one type of [<unknown>] buglet.
5334 * WHOIS and IDENTIFY commands call the function
5335 silc_server_command_[whois/identify]_check function even if
5336 we are not router server.
5338 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Added --with-gmp configuration option. If set the GMP
5341 is always compiled in the SILC source tree. If not set then
5342 it is checked whether the system has the GMP3 installed. If
5343 it has then the GMP won't be compiled (the system's headers
5344 and library is used), if it doesn't have it then the GMP is
5345 compiled in the SILC source tree.
5347 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Changed RSA private exponent generation to what PKCS #1
5350 suggests. We try to find the smallest possible d by doing
5351 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5352 not security fix but optimization.
5354 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5356 * Added new config entry [Identity] to fork the server and run
5357 it as specific user and group. A patch from Bostik.
5359 * Imported Dotconf configuration library into lib/dotconf.
5360 This will be used to create the SILC configuration files later.
5361 It will appear in the distsribution after this commit.
5363 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * A big code auditing weekend happening. Auditing code for
5366 obvious mistakes, bugs and errors. Also, removing any code
5369 Removed files for being obsolete:
5371 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5372 inline in the file lib/silcutil/silcbuffer.h)
5374 o lib/silcutil/silcbufutil.c (the header has inline versions)
5376 Changed code to fix possible error conditions:
5378 o The buffer formatting routines now check that the destination
5379 buffer really has enough space to add the data. This applies for
5380 both buffer formatting and unformatting
5381 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5382 unformatting was changed to accomodate following rules:
5383 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5384 sent to the function while XXX_*STRING will not allocate or copy
5385 the data into the buffer. Instead it sets the pointer from the
5386 buffer into the pointer sent as argument (XXX_*STRING used to
5387 require that the pointer must be allocated already). This change
5388 makes this whole thing a bit more consistent and more optimized
5389 (note that the data returned in the unformatting with XXX_*STRING
5390 must not be freed now). The routines return now -1 on error.
5392 o Tried to find all code that use buffer_format and buffer_unformat
5393 and added return value checking to prevent formatting and
5394 especially unformatting errors and possible subsequent fatal
5397 o Changed ske->x and ske->KEY to mallocated pointers in
5398 lib/silcske/silcske.h. Fixed possible data and memory leak.
5400 o Added return value checking to all *_parse* functions. Fixed
5401 many memory leaks as well.
5403 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5404 so that buffer overflows would not happen. All code now also
5405 checks the return value as it can fail.
5407 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Added reconnection support to server if the normal server looses
5410 its connection to the router (for example if router is rebooted).
5411 The server performs normal reconnection strategy implemented
5412 to the server. Affected file silcd/server.c.
5414 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Added new packet type SILC_PACKET_SET_MODE that is used to
5417 distribute the information about changed modes (for clients,
5418 channels and clients channel modes) to all routers in the
5419 network. Updated the protocol specification accordingly.
5421 Added functions into silcd/packet_send.c and
5422 silcd/packet_receive.c: silc_server_send_set_mode,
5423 silc_server_set_mode.
5425 Added new files silcmode.[ch] into lib/silccore that implements
5426 the encoding and decoding of Set Mode Payload. Added new type
5427 SilcSetModePayload. Moved the definitions of different modes
5428 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5430 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5432 * Oops, a little mistake in server's connection authentication
5433 protocol. The protocol is not ended with FAILURE but with
5434 SUCCESS if the authentication is Ok. :) Affected file is
5437 * Implemented NICK_CHANGE notify handling in server in the file
5438 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5439 the local clients on the channel. After the changing nickname
5440 in router environment snhould work and the [<unknown>] nickname
5441 should appear no more.
5443 The silc_server_replace_id function that receives the Replace ID
5444 payload now sends the NICK_CHANGE notify type also in the file
5445 silcd/packet_receive.c
5447 * Changed WHOIS and IDENTIFY command to support the maximum amount
5448 of arguments defined in protocol specs (3328 arguments). This
5449 fixed a bug that caused problems when there were more than three
5452 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Added extra parameter, command identifier, to the
5455 silc_client_send_command so that explicit command identifier
5458 Changed that ID list routines uses specific command identifier
5459 when sending WHOIS/IDENTIFY requests to the server so that they
5460 can be identified when the reply comes back.
5462 Affected files lib/silcclient/command.[ch],
5463 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5465 * Added `sender' argument to silc_server_packet_send_to_channel
5466 to indicaet the sender who originally sent the packet to us
5467 that we are now re-sending. Ignored if NULL. Affected file
5468 silcd/packet_send.[ch].
5470 * Added some server statistics support in silcd/server_internal.h
5471 SilcServerStatistics structure and around the server code. Also
5472 send some nice statistics information when client is connecting
5475 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5477 * Fixed channel ID decoding in server's JOIN command reply in
5478 silcd/command_reply.c
5480 * Fixed braodcasting of replace ID payload to not to send it if
5481 we are standalone server in silcd/packet_receive.c.
5483 * Fixed all channel message sending routines to not to send
5484 packets to clients that has router set, since they are routed
5485 separately in the same function earlier. Affects file
5486 silcd/packet_send.c and all channel packet sending functions.
5488 * In USERS reply, res_argv[i] are not allocated, the table
5489 is allocated. Thus changed that free the table, not its
5492 * In server's whois_check and identify_check if the client is
5493 locally connected do not send any WHOIS commands - they are not
5496 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Fixed some minor bugs in client when sending WHOIS command. The
5499 arguments was in wrong order.
5501 * Removed statis function add_to_channel from server in
5502 silcd/command.c that was previously used with the joining but
5505 * Tested USERS command in router environment successfully with two
5506 routers, two servers and two clients.
5508 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5510 * Reorganized the USERS command and command reply in client library
5511 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5512 When the command is given by user we register a pending command
5513 callback that will reprocess the command after the reply has been
5514 received from the server. When reprocessing the packet we then
5515 display the information. Thus, the USERS information is displayed
5516 now in the command callback instead of in the command reply
5517 callback. The processing of the command is same as previously
5518 when server has sent the command reply in the JOINing process.
5520 * Added to USERS command in silcd/command_reply.c to join the client,
5521 we didn't use to know about, to the channel after we've created
5522 a client entry for it. Also, for clienet we did know already still
5523 check whether it is on the channel or not and add it if not.
5525 * Removed silc_server_command_join_notify as the function and its
5528 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Changed the client's pending command handling to the same as the
5531 server's pending command handling. It is also now possible to
5532 execute command reply functions from other command reply
5533 function as the function callbacks for commands and command
5534 replies are one and same. The pending commands are not static
5535 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5536 in client connection context. Thus, pending commands are server
5537 connection specific as it is convenient.
5539 Changed the function silc_client_command_pending and
5540 silc_client_command_pending_del and added new function
5541 silc_client_command_pending_check. Removed the
5542 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5545 * Added cmd_ident, current command identifier, to the client
5546 connection context in lib/silcclient/client.h to keep track on
5547 command identifiers used in command sending. Client's command reply
5548 function handling now supports the mandatory command identifiers.
5550 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5551 funtions in client to fully support pending command callbacks.
5553 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5554 as one of the arguments to the application in the command reply
5557 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5558 before first releasing SILC but came back. Now it is removed again
5559 and should come back nomore. The FORWARDED flag was used only
5560 by the JOINing procedure by forwarding the command packet to router.
5561 Now, the JOINing procedure has been changed to more generic (due
5562 to various router environment issues) and FORWARDED is not needed
5563 anymore for anything. The protocol specification is yet to be
5566 Now, removed silc_server_packet_forward from server and the flag
5567 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5569 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Renamed NAMES command to USERS command. The NAMES was named that
5572 due to historical reasons. Now it is renamed. Also, rewrote
5573 parts of the USERS command. The nickname list is not sent anymore
5574 by the server. Only Client ID and mode lists are sent in the USERS
5575 command. Changed this also to the protocol specification.
5577 The client now resolves the names and stuff after it receives
5578 the USERS list from the server when joining to the channel.
5580 * WHOIS and IDENTIFY commands has been changed to support multiple
5581 Client ID's per command. One can now search for multiple users
5582 in the network by sending only one WHOIS or IDENTIFY command.
5583 Changed the code and the protocol specifications.
5585 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5586 uses silc_server_command_whois_parse to parse the request. */
5588 * If normal server, do not parse the WHOIS and IDENTIFY requests
5589 before sending it to the router. Saves some time.
5591 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Fixed JOIN command on client library. Wrong number of arguments
5594 used to crash the client.
5596 * Added silc_server_channel_has_global function to check whether
5597 channel has global users or not.
5599 * Added silc_server_channel_has_local function to check whether channel
5600 has locally connected clients on the channel.
5602 * The silc_server_remove_from_one_channel now checks whether the
5603 channel has global users or not after given client was removed from
5604 the channel. It also checks whether the channel has local clients
5605 on the channel anymore. If it does not have then the channel entry
5606 is removed as it is not needed anymore.
5608 * The silc_server_notify now checks on JOIN notify whether the joining
5609 client is one of locally connected or global. If it is global then
5610 the channel has now global users on the channel and that is marked
5611 to the channel entry. Also, it now saves the global client to
5612 global list who is joining and JOINs it to the channel. This is
5613 for normal server, that is.
5615 Changed silc_server_send_notify_on_channel,
5616 silc_server_packet_relay_to_channel and
5617 silc_server_packet_send_to_channel check if we are normal server
5618 and client has router set (ie. global client) do not send the
5619 message to that client, as it is already routed to our router.
5621 * Implemented LEAVE notify type handling in silc_server_notify
5624 * Tested LEAVE command in router environment successfully. Tested
5625 with two routers, two servers and two clients.
5629 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5631 * Implemented SIGNOFF notify type handling in silc_server_notify
5634 * silc_server_remove_id now removes the client entry from all channels
5635 it has joined and thusly sends SIGNOFF notify type.
5637 * Rewrote the NAMES list generation in server by removing two excess
5638 loops. The lists are created now inside one loop.
5640 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * silc_server_remove_channel_user checks now also global list
5643 for channel and client.
5645 * silc_server_new_channel_user checks now both local and global
5646 list for channel and client. Fixed a bug in client id decoding.
5647 Used to decode wrong buffer.
5649 * silc_server_channel_message checks now both local and global
5650 list for channel entry.
5652 * Tested channel joining (hence JOIN) in router environment
5653 successfully. Tested with two routers, two servers and two
5656 * Tested channel message sending in router environment successfully.
5658 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * Added silc_server_save_channel_key into server.[ch] to save the
5661 received channel key in Channel Key payload processing. It is
5662 also used in JOIN command reply handling.
5664 Equivalent function silc_client_save_channel_key added into
5665 client.[ch] into client library.
5667 * Changed JOIN command reply to send information whether the channel
5668 was created or not (is existing already) and the channel key
5669 payload. Changed protocol specs accordingly.
5671 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5672 the request was sent by ID and not by nickname. Crashed on
5675 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5678 now correctly save the received data.
5680 * silc_server_free_sock_user_data now notifies routers in the
5681 network about entities leaving the network.
5683 At the same time implemented functions silc_server_remove_id
5684 and silc_server_send_remove_id to receive and send REMOVE_ID
5685 packets. The packet is used to notify routers in the network
5686 about leaving entities. The ID removed will become invalid in
5689 * Added function silc_idlist_del_server into server. Removes and
5690 free's server entry from ID list.
5692 * silc_server_private_message function now checks, if we are router,
5693 that the destination ID really is valid ID, naturally.
5695 * In router when NEW_ID packet is received (for new client) the
5696 hash of the Client ID is saved in the ID Cache but the
5697 client->nickname is set to NULL, instead of putting the hash
5700 IDENTIFY command now also checks that client->nickname must be
5701 valid. If it is not if will request the data from the server who
5702 owns the client. Added new function
5703 silc_server_command_identify_check.
5705 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5706 to set the command to already allocated Command Payload.
5708 * Tested private message sending in router environment with two
5709 routers, two servers and two clients. Fixed minor bugs and now
5712 * Fixed segfault from client's NAMES command. Used to crash if
5715 * Forwarded packets must not be routed even if it is not destined
5716 to the receiver. Changed server code comply with this.
5718 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Added `require_reverse_mapping' boolean value to ServerParams
5721 structure. If TRUE (not default) the server will require that
5722 the connecting host has fully qualified domain name.
5724 If the reverse mapping is not required and hostname could not be
5725 found the IP address is used as hostname.
5727 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Implemented version string checking to both client and server.
5730 The check is incomplete currently due to the abnormal version
5731 strings used in development version of SILC.
5733 * Changed all command functions in server to use the new
5736 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Changed char *data to unsigned char *data in ID Cache system to
5739 support binary data as ID Cache data. Changed code to support
5740 binary data in lib/silccore/idcache.c.
5742 * Renamed silc_server_packet_relay_command_reply to
5743 silc_server_command_reply as it is normal packet receiving
5744 function. Rewrote the function to accept command replys for
5745 servers and not only for clients.
5747 * Mark remote router always as registered server if we are connecting
5748 to it. Otherwise, commands sent by the router to us are ignored.
5750 * All ID List find routines now returns the ID Cache Entry pointer
5751 as well if requested.
5753 * WHOIS command works now in router environment, tested with two
5754 routers, two servers and two clients.
5756 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5757 in router environment (as it is almost equivalent to WHOIS) but
5758 hasn't been tested thoroughly. Added new functions:
5760 silc_server_command_identify_parse
5761 silc_server_command_identify_send_reply
5762 silc_server_command_identify_from_client
5763 silc_server_command_identify_from_server
5765 * Disabled route cache adding because adding two different ID's with
5766 same IP replaces the old cache entry thus giving wrong route.
5767 The entry->router->connection is always the fastest route anyway
5768 so route cache may not be needed. Of course, new routes maybe
5769 established after receiving the ID when the entry->router->connection
5770 might not be anymore the most optimal.
5772 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Add route cache for received ID for fast routing.
5776 * Added silc_server_packet_route to route received packet on router
5777 that is not destined to us.
5779 * Renamed silc_server_get_route to silc_server_route_get.
5781 * Added id_string and id_string_len fields into SilcServer to
5782 include encoded ServerID for fast comparing without excess
5783 encoding of the ID's.
5785 * Cleaned up WHOIS command on server side. Added following static
5788 silc_server_command_whois_parse
5789 silc_server_command_whois_check
5790 silc_server_command_whois_send_reply
5791 silc_server_command_whois_from_client
5792 silc_server_command_whois_from_server
5794 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5795 arguments in command replies. All command functions should be
5796 updated to use this macro.
5798 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Minor typo fixes on command reply handling on server.
5802 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * Added silc_server_command_add_to_channel internal routine to add
5805 the client to the channel after router has created the channel and
5806 sent command reply to the server.
5808 * Added generic silc_server_send_command to send any command from
5811 * Use static buffer with ID rendering instead of duplicating data.
5813 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Fixed a channel user mode bug when joining to a channel server gave
5816 everybody channel founder rights, oops.
5818 * We mark ourselves as the router of the incoming server connection
5819 if we are router ourselves. This way we can check in some packet
5820 sending functions whether it is locally connected server. For
5821 incoming router connections we put NULL.
5823 * For router sending packets locally means now always sending the
5824 packet cell wide; to local clients and local servers. For normal
5825 server sending packet locally means sending it to only local
5828 * Fixed the JOIN command to really work in router environment. If the
5829 channel is created it is always created by the router. Router is
5830 also responsible of making the initial joining to the channel,
5831 sending JOIN notify to the sending server and distributing
5832 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5833 does not exist server doesn't do anything else but forward the
5834 command to the router which performs everything.
5836 * Added silc_server_send_channel_key function to send the Channel Key
5839 * Added silc_server_create_channel_key to create new channel key. The
5840 channel key is now re-generated everytime someone joins or leaves
5841 a channel, as protocol dictates. Note: channel->key_len is the
5844 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5847 packet_receive.[ch] to separate packet sending and receiving
5848 routines. The server.[ch] now includes everything else including
5849 actual packet processing (writing and reading data) and other
5852 Renamed silc_server_private_message_send_internal to
5853 silc_server_send_private_message. The routine is still though
5854 used only to relay private messages as server does not send
5855 private messages itself.
5857 Renamed silc_server_new_channel to silc_server_create_new_channel
5858 and added new function sicl_server_new_channel that handles the
5859 incoming New Channel packet. Added also new sending function
5860 silc_server_send_new_channel to send New Channel Payload.
5862 * Added new function silc_server_notify to process incoming notify
5863 packet to the server/router. Server may then relay the notify
5864 to clients if needed.
5866 * Added new function silc_server_new_channel_user to process incoming
5867 New Channel User packet. Router will redistribute the packet and
5868 send JOIN notify to its local clients and locally connected servers
5869 if needed. Normal server will send JOIN notify to its local client
5870 on same channel when received this packet. Added also corresponding
5871 sending function silc_server_send_new_channel_user to sent the
5874 * Added boolean route argument to send_notif_to_channel and
5875 packet_send_to_channel functions to attempt to route the packet
5876 if it is TRUE and send only locally if it is FALSE.
5878 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5880 * silc_server_replace_id now broadcasts the received replace ID
5881 packet if it is not broadcast packet already. The router must
5882 broadcast to inform other routers about changed ID.
5884 * Added backpointer to server's router into SilcServer context in
5885 silcd/server_internal.h.
5887 * Fixed silc_server_packet_broadcast to send correct broadcast
5890 * The channel key is now distributed to the local client as soon
5891 as it is received from the router (in router environment) so that
5892 no other packet may be sent for the channel until client has
5895 * silc_server_remove_channel_user now broadcasts the received
5896 Remove Channel User packet if it is not broadcast packet already.
5897 The router must broadcast to inform other routers about removed
5900 * Added users field into SilcPacketContext that is a reference count
5901 of the context. One can increase the reference count by calling
5902 silc_packet_context_dup which is now changed to just increase the
5903 reference count instead of duplicating the data. The reference
5904 count is decresed by calling silc_packet_context_free that will
5905 free the data after the reference count hits zero.
5907 For now on the packet context and everything allocated into it
5908 (including the raw packet from network) must be freed by calling
5909 the new silc_packet_context_free function. Added also new function
5910 silc_packet_context_alloc that must be used now to allocate the
5911 context. This also means that if a routine is asynchronous from
5912 silc_[client/server]_packet_parse_type the packet context must
5913 be duplicated by calling silc_packet_context_dup. Otherwise it
5914 gets free'd after silc_[client/server]_packet_parse_type returns.
5915 Also, one must remember that if packet is duplicated then its
5916 reference count must be decresed by calling the free function as
5917 many times as it was duplicated.
5919 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5920 from both client and server.
5922 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Made joining to a channel working in router environment.
5926 * Cleaned up JOIN command on server side and create function
5927 silc_server_command_join_channel internal routine to make the
5930 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5932 * Changed silc_command_pending list to SilcDList. Also, added
5933 `ident' field to SilcServerCommandPending structure to identify
5934 the reply and to call correct callback.
5936 Added silc_server_command_pending_check function to replace the
5937 corresnponding macro. The silc_command_pending list is not
5940 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5941 to set identifier to previously allocated Command Payload. It
5942 is used to set identifier for command when resending Command
5945 * Added silc_command_payload_encode_payload to encode Command
5946 Payload buffer from SilcCommandPayload structure.
5948 * Added silc_argument_payload_encode_payload to encode Argument
5949 payload buffer from SilcArgumentPayload structure.
5951 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5953 * Changed WHOIS command to support router connection on server side.
5954 The whois request is always sent to router unless the server is
5955 standalone server. After server has received the reply from the
5956 router will it send the reply to the client.
5958 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5959 broadcast received broadcast packet. The function is used only
5960 by router. The broadcast packet is always sent to the router's
5963 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5964 render given ID to printable string, for log files for example.
5966 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Made basic router to router connections working. At least they
5969 can now connect to each other but nothing really works the way
5970 they are supposed - yet.
5972 * Added new initiator token to RouterConnection configuration
5973 file in silcd/serverconfig.[ch]. It is used to tell whether we
5974 are the initiator to the remote router or whether we'll expect
5975 the other end to connect.
5977 * Moved registering of listener task to silc_server_init, hence
5978 the server starts listenning as soon as it is run, even if it
5979 does not have connections to other routers. Let's see how well
5982 * Changed default connection retry timeouts for more suitable in
5985 * Removed cipher and such arguments from silc_idlist_add_client
5986 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5987 Added new function silc_idlist_add_data to add the keys and stuff
5990 * Added SilcIDListData structure and added it to SilcClientEntry
5991 and SilcServerEntry as their first field in the structure. This
5992 way we can explicitly cast the ID entries to the SilcIDListData
5993 structure and get common data for the entries. In past, we had
5994 to first check what type of connection it is and then cast it to
5995 correct ID entry type. Now, we can directly cast the opaque
5996 pointer to the SilcIDListData (no matter what ID entry it actually
5997 is) and get the data needed.
5999 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6002 in some circumstances even if threre were timeout tasks, though not
6003 IO tasks, but tasks anyway. Now fixed.
6005 * Defined SilcServerConnection structure to hold connection specific
6006 stuff about directly connected servers and routers. The definition
6007 is currently in silcd/server_internal.h. I thought about having
6008 a bit more important role fro this struct but for now it is used
6009 only when connecting to other server (or router actually).
6011 * Added connecting retry support in server when connecting to
6012 router(s). The retry feature implement exponential backoff
6013 algorithm. Also, added SilcServerParams structure to hold default
6014 parameters for server. For now, it include these retry settings
6015 and are hard coded. After server is moded to be as Silc Server
6016 Library this structure will be more important.
6018 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6020 * Changed client librarys channel->clients table to SilcList and
6021 changed code accordingly.
6023 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Changed client's channel table to SilcList and changed code
6026 accordingly. Also changed SilcChannelClientEntry to include back-
6027 pointer to the channel so that client entry can use that structure
6028 as list as well and we have fast cross-reference to the channel.
6029 This change dramatically decreased the complexity of channel
6030 handling with client entry and vice versa (removed one extra
6031 loop when searching for channel entry from many functions).
6033 * Changed server->sim from table to SilcDList and changed code
6036 * NAMES command can now be used from user interface. It will show
6037 the user list on the channel, neatly.
6039 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6040 Code now saves realname of the user if it becomes available.
6042 * Renamed configure.in to configure.in.pre and made ./prepare
6043 script to automatically add correct version string to
6044 configure.in which it creates from configure.in.pre.
6046 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6048 * NAMES command reply now shows users mode with the nickname when
6051 * Moved silc_client_ch[u]mode[_char] functions from
6052 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6053 place sucks, they are utility functions and should be in some
6056 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6058 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6061 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6065 * Added TRQ (efficient deque and list library) into lib/trq. This is
6066 a very good list library that is currently used in the SILC. Defined
6067 SilcList API over the library because I didn't like the API very
6068 much. See lib/trq/silclist.h for the API and examples of how to
6069 use the API. Fixed various places in the code to use the new
6070 SilcList API. The SilcList is meant for lists that has a structure
6071 already defined as a list. It is not suitable to add just some
6072 context to the list (in TRQ, the context is the list actually).
6074 So, I defined SilcDList that can be used for the purpose where
6075 predefined list structure does not exit. This can be used as
6076 such list. Now some context just can be added to the SilcDList.
6077 Currently this list is not used in the SILC just yet, though there
6078 are a lot places where this can replace dynamically allocated
6079 tables and I will fix these places, later, to use SilcDList.
6080 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6081 and use TRQ internally).
6083 Also fixed some annoying warning messages that the original TRQ
6084 code generated. Also minor changes to TRQ's Makefile.in.
6086 * Added support for querying by Client ID to both WHOIS and
6087 IDENTIFY commands into server, as required by the protocol.
6089 * Removed method function pointers from SilcBuffer structure. They
6090 weren't used to anything and just increased the context size for
6091 no good reason. This change also made silc_buffer_alloc and
6092 silc_buffer_free functions inline functions.
6094 * Disabled command flooding detection support until it's fixed so
6095 that it accepts commands in but does not execute them more than once
6098 * Added silc_net_localhost(), to return local hostname, into
6099 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6100 that must be initialized before calling silc_client_init.
6102 * Added new function: silc_server_send_notify_on_channels to send
6103 notify messages to all channels client has joined. It is assured
6104 that the message is sent only once per client.
6106 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6107 lib/silcutil/silcutil.[ch] as silc_format function. The new
6108 function is generic and is used by server as well, not only by
6109 the logging routines.
6111 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6112 the provided version string was not acceptable. Added new function:
6113 silc_ske_check_version into lib/silcske/silcske.h. The function
6114 must be implemented by the application (client or server) and it
6115 does not reside in the SKE library. The function checks the version
6116 string remote end sent.
6118 * Added back pointers (to opaque context and to SilcSocketConnection)
6119 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6121 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6122 duplicate packet context structure.
6124 * Changed `notify' client operation to send same arguments as client
6125 receives from server except for ID's. ID's are mapped to correct
6126 ID entry and that is returned. Also, if channel entry is not sent
6127 by server but the notify is for channel the channel entry is sent
6128 to application (otherwise application doesn't know that it is for
6129 channel (library gets it from packet's Destination ID)).
6131 * Added silc_client_remove_from_channels into client library to
6132 remove a client from all channels it has joined to. Used when
6133 received SIGNOFF notify from server. Added also new function
6134 silc_client_replace_from_channels to replace old ID entry with
6135 new ID entry on all channels. Used when received NICK_CHANGE
6138 * Fixed ID Cache list handling in silc_idlist_get_client in
6139 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6140 to get (or query) client by ID.
6142 * Updated TODO list.
6144 * Added connection authentication status message defined by the
6145 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6146 support for these into the code in client and server side.
6148 * Added generic function silc_client_send_command to send any command
6149 with variable argument list. Application should use this function
6150 to send commands if the command functions provided by the library
6151 does not suite for the application's user interface needs.
6153 * Added new `failure' client operation. Application is notified about
6154 received failure packet if client is executing a protocol. In this
6155 case the protocol's execution has failed.
6157 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6158 is required by the protocol.
6160 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6161 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6164 * Added status flag to SilcSKE object to indicate realtime status
6165 of the SKE protocol.
6167 * Application receives now exactly same command reply arguments as
6168 the library receives from server. However, if ID is received the
6169 corresponding ID entry is returned to the application (eg. Client
6170 ID is mapped to correct SilcClientEntry entry and that is returned).
6171 Changed command_reply client operation due to this change.
6173 * Changed all ID's in commands and in command replys as ID Payloads.
6174 Change affected both client and server side codes.
6176 All ID's sent in SILC network (with execption of ID's in SILC
6177 Packet header) are sent in ID Payload to support variable length
6180 * Server now notifies nick changes and notifies all clients on
6181 the channels about the new nickname (about the new Client ID,
6184 * Implemented CMODE command to change channel modes. Supports all
6185 channel modes defined by the protocol specs except ban and invite
6186 lists. (Also, private channel key mode is supported but support for
6187 setting private channel key in client is missing, thus, this mode
6188 has no effect on client side (except that server requires that the
6189 client uses private channel key and normal channel traffic does not
6192 Also, invite mode works per se, but INVITE command does not work
6193 yet correctly, so you can set channel as invite only channel but
6194 inviting clients to the channel does not work (it is yet to be
6195 thought what's the best way to do it).
6197 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6198 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6199 Implemented CUMODE command to change user's mode on the channel.
6200 Supports all modes defined by the protocol specs.
6202 * Added NAMES command reply to return users modes on the channel.
6204 * Removed unnecessary and slow ciphers from lib/silccrypt.
6206 * Set SO_KEEPALIVE option to connection sockets by default.
6208 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6210 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6211 redefined the Notify Payload into protocol specs.
6213 * Added silc_id_payload_parse_id to get ID directly from raw
6216 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6219 accept searching by Client ID as well.
6221 * Added support for LEAVE and SIGNOFF notify types in client library.
6223 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6224 to parse ID Payload from raw data.
6226 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6228 * Added flags parameter into silc_ske_assemble_security_properties
6229 function in lib/silcske/silcske.[ch].
6231 * Changed notify client operation to fit better for notify messages
6232 sent by server. The notify payload received from server is now
6233 passed to the application (after parsing it to SilcNotifyPayload).
6234 It is application's responsibility to retrieve the arguments
6235 from the payload and show the message the way it wants. The message
6236 sent by server is implementation specific.
6238 * Changed public keys to comply with the protocol specification.
6239 Old public keys are not supported anymore and are not compatible.
6241 * Removed nickname from Channel Payload as the latest draft removed
6242 it. The client must resolve the nickname from the NAMES command
6243 reply received when it joined the channel.
6245 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6247 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * Fixed some errors in protocol specification drafts.
6251 * Created lib/silccore/silcnotify.c to implement Notify Payload
6252 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6253 generic payloads described by protocol specifications. The file
6254 includes implementations for ID Payload and Argument Payload.
6256 * Changed Command Payload implementation to use the new Argument
6257 Payload. Changed command_xxxx_payload to command_payload_xxxx
6258 to comply with SILC coding conventions.
6260 * Added suppport for Argument Payload handling in Notify Payload
6261 implementation as protocol requires it. Added the new support
6262 into server and client lib as well.
6264 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6266 * Added support for multiple nicknames on same channel. [n] is
6267 added locally to the nickname if there are more than one same
6268 nicknames on the channel.
6270 * Server now sends all nicknames that matched WHOIS request.
6271 Client also shows the list received from server.
6273 * Added TOPIC command to client side. User can now set and show
6274 current topic on channel.
6276 * Added MOTD command to client and server. Also, server sends the
6277 motd when client connects to the server.
6279 * Changed version strings to comply ISO 8601.
6281 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Fixed protocol error handling in client library. It should now
6284 cope even if the SKE fails for some reason.
6286 * Made new protocol specification drafts for submitting to IETF.
6288 * Implemented TOPIC command to server in silcd/command.c.
6290 * Added two new notify types into lib/silccore/silcnotify.h:
6291 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6292 notify nickname change and topic setting/change on a channel.
6294 * API change of command_reply operation in client library. The
6295 application gets now the status type received from server as well.
6297 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6299 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6301 * Cras fixed and optimized the packet handling even further and
6302 it should work now. Minor change to the prototype of function
6303 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6305 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Added new function into lib/silcutil/silcschedule.[ch]:
6308 silc_schedule_with_fd to select() a specified fd. The function
6309 returns after timeout expires or data arrives or goes. The
6310 function is used by packet routines to wait that all data is
6311 received from network.
6313 * Fixed data reading from network in lib/silccore/silcpacket.c.
6314 The code now assures that all data is read from the fd and then
6315 continues packet processing. This was a bug fix since the code
6316 used to drop some data in some circumstances.
6318 * Added new function into lib/silcclient/client.[ch]:
6319 silc_client_start_key_exchange to start key exchange after
6320 connection has been established to server. The code internally
6321 now uses this funtion but its main purpose was to provide it
6322 for applications that perform their own connecting. After
6323 application has created a connection it merely calls this
6324 function to start the key exchange between client and server.
6325 The library takes care of everything else after that.
6327 Updated also lib/silcclient/README to explain the usage of
6330 * Do not send to application information that connection has
6331 been established. Application gets notified it by connect
6334 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Applied cras's patch to add silc_schedule_one function. The
6337 function runs scheduler once and returns.
6339 * Fixed the scheduler after cras messed it up. The timeout
6340 handling works now as it's supposed to work.
6342 * Added into lib/silccore/ silcnotify.h to include notify
6343 message types support. Changed silc_server_send_notify*
6344 functions, in server.[ch], to support those new notify types.
6345 Added the support for the notify types into client library,
6346 as well. Added new notify client operation into ops.h in
6349 * Changed silc_server_packet_send_to_channel to send normal
6350 packets instead of just channel message packets. The function
6351 is now used to send the notify packets to channels. It is not
6352 used to send channel message packets anymore, as server never
6355 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6356 va_arg()s as it seems to require it nowadays. I guess, if SILC
6357 is compiled with older va_arg() the new code should work anyway.
6359 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6361 * Splitted core library. Core library (lib/silccore) includes
6362 now only SILC protocol specific core (and common) components.
6363 Created new utility library (lib/silcutil) that includes more
6364 generic purpose stuff. The stuff for util library was taken
6365 from the old core library. This was minor and easy split.
6367 * Created SILC Client Library (lib/silcclient) that includes
6368 implementation of the SILC client without user interface. This
6369 was major move from silc/ directory. The code has been changed
6370 so that it is transparent towards the user interface. The
6371 silc/ directory includes now the same user interface as before
6372 and it uses the new client library. Read lib/silcclient/README.
6373 Basicly, the client library performs everything else related
6374 to SILC except user interface handling. Also, configuration
6375 files are considered to be part of user interface and library
6376 does not handle them.
6378 This change also changed a lot of structures, function naming etc.
6379 Most important change was that SilcClientWindow object was
6380 renamed to SilcClientConnection in the client library. Created
6381 also new file lib/silcclient/ops.h. Also added new files
6382 silc/local_command.[ch] and silc/client_ops.[ch].
6384 All these changes were made to make it easier for user interface
6385 designers to create what ever user interface for the SILC client
6388 It is also expected that the server will be moved to lib
6389 directory as well and SILC Server Library will be created;
6390 sometimes in the future.
6392 * Removed Local commands from lib/silccore/silccommand.h as
6393 they are application specific and new client library does not
6394 handle any of those anymore.
6396 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6397 old client implementation in silc/.
6399 * Added support for callback functions in SILC_LOG_* macros.
6400 Application can now set its own callbacks that will be called
6401 instead of using the default functions that will always print
6402 the debug messages to stderr (or stdout). Also, debugging can
6403 now be disabled by setting silc_debug to FALSE and re-enabled by
6404 setting it to TRUE. Note, that logging will still work even
6405 if debugging is disabled.
6407 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6408 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6409 silc_log_reset_debug_callbacks.
6411 * To enable debugging in silc client one must give now -d
6412 option on command line.
6414 * Changed silc_schedule_init to automatically allocate task queues
6415 if they are not allocated before calling it.
6417 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6419 * Added GMP 3.1 into math library.
6421 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6424 a channel in SILC network. The packet is used by servers and
6425 routers to notify other routers that user has left a channel.
6426 This little feature was missing until now. Added the feature
6427 to protocol specification as well.
6429 Added functions: silc_server_send_remove_channel_user and
6430 silc_server_remove_channel_user into server.[ch].
6432 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6433 lib/silccore/silcpacket.h. However, they are not implemented
6436 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Fixed joining to a channel and sending channel messages
6439 between server and router. The channel message sending should
6440 now work inside a cell.
6442 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6444 * Fixed the private message sending between server and router.
6445 The private message sending should now work inside a cell.
6447 * Added silc_server_replace_id into server.[ch] to replace
6448 existing ID in the SILC network.
6450 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6451 and silc_idlist_replace_server_id into idlist.[ch] in server.
6453 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6455 * Fixed the server to server connections. Server can again now
6456 connect to router. Router to router connections probably does
6459 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Added dynamic protocol registering support. Now protocols can
6462 registered and unregistered on the fly. Patch by cras.
6464 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * Added lib/contrib directory to hold routines that some platforms
6467 don't have but are needed by SILC.
6469 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6470 into lin/contrib to provide getopt() and getopt_long() for
6471 those who don't have it.
6473 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Added AWAY command to client. When away message is set and
6476 client receives a private message packet the client automatically
6477 replies to the sender with the away message.
6479 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6480 bug seemed to be the cause of recent problems when compiling
6483 * Added version detection support to SKE protocol specification
6484 and added the new changes to the SKE implementation as well.
6485 There were other minor changes in the SKE protocol as well.
6487 Many changes in lib/silcske/silcske.[ch] and in
6488 lib/silcske/payload.[ch].
6490 * Added ^U functionality, clear input line. Patch from cras.
6492 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6494 * Mainly small bugfixes on core library. Fixed some debugging
6495 logging and buffer overflow in silclog.c.
6497 * Updated config.sub and config.guess on the distribution tree.
6499 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6501 * Added command lagging support in server. Client may execute
6502 commands now only once in two seconds.
6504 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * Optimized packet reception. MAC computation and checking is now
6507 also more optimized. A lot previously duplicated code is now
6508 used as generic by both client and server.
6510 * Fixed key pair generation in clientutil.c
6512 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Added into lib/silccore/silcbufutil.[ch] new function;
6515 silc_buffer_realloc.
6517 * Moved generic packet sending/encryption functions to
6518 lib/silccore/silcpacket.[ch] from client and server. Some
6519 rewriting of the functions.
6521 * Moved all generic packet reception/decryption functions to
6522 lib/silccore/silcpacket.[ch] from client and server. The
6523 packet processing is now much cleaner in both client and server.
6524 These were major changes in both client and server.
6526 * Created many common functions in server to do packet sending.
6527 Previously code were duplicated a lot, this has been removed
6530 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * Rewrote major parts of the ID cache system. Don't know
6533 whether it is better now or not but at least the API is more
6536 * Major rewrite on ID cache stuff on client because of the ID
6537 cache API changes. Added idlist.c to client.
6539 * Also major rewrite on ID cache stuff on server as well.
6540 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6541 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6542 in hand, instead they are all put into the ID cache system now.
6543 All server_idlist_* routines uses ID cache now instead of
6544 traversing its own lists (those lists does not exist anymore).
6545 SilcIDList though still exists. Also, SilcXXXEntry's are
6548 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Finally made the SKE implementation compliant to the protocol
6551 specification. All mp integers are now binary encoded as
6552 opposed being HEX encoded.
6554 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6557 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6558 functions: silc_[encode/decode]_pem. Also added function
6559 silc_encode_pem_file to PEM encode with newlines ('\n') for
6562 * SILC public keys are now encoded either PEM or binary. Same
6563 option is for private keys as well. By default private keys
6564 are binary encoded and public keys PEM encoded. Silly HEX
6565 encoding were removed.
6567 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6568 function to create fingerprints.
6570 * Fixed a bug in SHA1; does not change the original data anymore.
6572 * Partly implemented INFO command on client and server side.
6573 Fixed CLEAR command. Changes to SERVER command; show current
6574 server(s) when giving command without arguments. Added
6575 VERSION command to client.
6577 * Added check to server that unregistered connections cannot
6578 execute commands (unless it is specificly allowed).
6580 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6582 * Fixed screen refresh.
6584 * Fixed channel joining bug from client. On some circumstances
6585 client tried to join to a channel it had already joined.
6587 * Added public key verification process into client's protocol.c.
6588 The client now verifies the public key from user and saves
6589 it into ~./silc/serverkeys/ directory.
6591 Added into: clientutil.[ch]: silc_client_verify_server_key.
6593 * Changed SKE protocol's silc_ske_initiator_finish function
6594 to accept callback function that verifies the received public
6595 key. Removed old silc_ske_verify_public_key function.
6597 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6599 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6600 silc_pkcs_private_key[_data]_set.
6602 * Made the password and public authentication more cleaner in
6603 server's protocol.c.
6605 * Removed historic and obsolete protocol `channel_auth' from
6606 both client and server.
6608 * Removed wrong way of sending command status messages from
6609 server to client in server's command.c. The old way violated
6610 protocol specification.
6612 Changes to silccore/silccommand.[ch]: removed
6613 silc_command_encode_status_payload -> not needed anymore,
6614 changed silc_command_encode_payload_va to accept extra
6615 argument on variable argument list. The argument type must
6616 now be provided to the function. Also, added new function:
6617 silc_command_encode_reply_payload_va which is same as
6618 normal command_encode_payload_va except command status type
6619 is provided as extra argument.
6621 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6623 * Added ~./silc directory handling. The directory includes the
6624 public and private keys for the client.
6626 Added silc_client_check_silc_dir, silc_client_create_identifier
6627 and silc_client_load_keys.
6629 * Implemented SILC protocol compliant public key. Added public
6630 and private key saving to and loading from files.
6632 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6633 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6634 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6635 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6636 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6638 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6639 silc_pkcs_load_[public/private]_key.
6641 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6643 * Added silc_server_get_route (route.[ch]) to get connection
6644 data for the fastest route for given ID.
6646 * Implemented INVITE command on client and server. The command
6647 were re-defined in the SILC Protocol Specification and the
6648 implementation now complies with the specification.
6650 * Implemented PING command on client and server.
6652 * Implemented NAMES command on client and server. The server side
6653 supports currently only normal server not router server yet.
6654 Some changes to NAMES definition in SILC protocol specification.
6656 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Implemented LEAVE command on client and server.
6660 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6661 again. This change was made to the protocol as well. Server
6662 should not violate the protocol specification anymore.
6664 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6666 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6667 was tested. SOCKS4 was not but should work anyway.
