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

684 to run server on foreground. A patch by debolaz.
685 Affected files silcd/server.c, silcd/silcd.c.
687 * Fixed MOTD to return the MOTD file server name. Affected
688 file silcd/command.c.
690 * Added INFO command reply handling to the Irssi SILC Client.
691 Affected file irssi/src/silc/core/client_ops.c.
693 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
695 * Fixed the silc_idcache_list_* routines to really support
696 the dynamic list. Fixes a crash. Affected file is
697 lib/silccore/silcidcache.c.
699 * Fixed the LIST command reply to really call LIST command's
700 pending callbacks. Affected file silcd/command_reply.c.
702 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Update conn->local_entry->nickname after giving NICK
705 command. Affected file lib/silcclient/command.c.
707 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
709 * Added the [pid] option to the silcd configuration file
711 Affected files: serverconfig.[ch] and silcd.c
713 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
715 * Save fingerprint in WHOIS command reply in server.
716 Affected file silcd/command_reply.c.
718 * Fixed NICK commands pending callback registration.
719 Affected file lib/silcclient/command.c.
721 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
723 * Use ++server->cmd_ident when sending commands in server,
724 instead of random number. Affected file silcd/command.c.
726 * Fixed GETKEY command reply to call actually GETKEY pending
727 command callbacks. Affected file silcd/command_reply.c.
729 * A bit stricter check for nicknames. Check for same nickname
730 in NICK command also. Affected file silcd/command.c.
732 * Do not call INFO command everytime client ID changes, only
733 during first connecting. Affected file lib/silcclient/client.c.
735 * Set the new nickname only after successful command reply for
736 NICK command is returned by server. Affected file
737 lib/silcclient/command.c.
739 * Remove nicknames from nicklist during server_signoff notify.
740 Should fix /NAMES bit more. The affected file is
741 irssi/src/silc/core/silc-channels.c.
743 * Added `fingerprint' field to the SilcIDListData in the
744 silcd/idlist.h to hold the fingerprint of the client's
747 Send the fingerprint of the client's public key in WHOIS
750 Affected files silcd/command.c, and silcd/idlist.[ch].
752 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
753 create fingerprint from given data.
755 * Show the fingerprint of the client's public key in WHOIS.
756 Affected files irssi/src/module-formats.[ch] and
757 irssi/src/silc/core/client_ops.c.
759 * Format the multiple same nicknames also during JOIN and
760 NICK_CHANGE notifys. Affected file is
761 lib/silcclient/client_notify.c.
763 * Do not print error on screen for invalid private message
764 payload since it can come if someone is sending private
765 messages with wrong key. Affected file
766 lib/silccore/silcprivate.c.
768 * Fixed multiple concurrent /PING crash. Affected file
769 lib/silcclient/command.c.
771 * Changed the wrong ID encoding. All IP addresses must be
772 in MSB first order in encoded format. They were encoded
773 wrong and was in LSB format. Affected files are
774 silcd/serverid.c, lib/silcutil/silcutil.c.
776 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
778 * Call the `connect' client operation through the scheduler
779 in case of error. Affected file lib/silcclient/client.c.
781 * Call the `failure' client operation even if the error
782 occurred locally during a protocol. Affected file is
783 lib/silcclient/protocol.c.
785 * Added support of sending LIST command to router from normal
786 server. This way normal server can get list of all channels
787 in the network too. Fixed the channel list sending in the
788 server too. Affected files are silcd/command.c, and
789 silcd/command_reply.[ch].
791 * Added silc_server_update_channels_by_server and
792 silc_server_remove_channels_by_server. They are used during
793 disconnection of primary router and in backup router protocol.
794 Affected file silcd/server_util.[ch], silcd/server.c and
795 silcd/server_backup.c.
797 * Fixed channel adding to global list in IDENTIFY command
798 reply in server. Affected file silcd/command_reply.c.
800 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
802 * If the incoming packet type is REKEY or REKEY_DONE process
803 that packet always synchronously. Fixes yet another MAC
804 failed error on slow (dialup) connections. Affected file
805 lib/silcclient/client.c and silcd/server.c.
807 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
809 * Call check_version SKE callback for initiator too. Affected
810 file lib/silcske/silcske.c.
812 * Implemented fix for security hole found in the SKE that was
813 fixed in the specification few days back; the initiator's
814 public key is now added to the HASH value computation.
815 Added backwards support for the old way of doing it too, for
816 old clients and old servers. Affected file is
817 lib/silcske/silcske.c.
819 * Enabled mutual authentication by default in SKE. If initiator
820 is not providing mutual authentication the responder will
821 force it. This will provide the proof of posession of the
822 private key for responder. The affected files are
823 lib/silcclient/protocol.c and silcd/protocol.c.
825 * Do not cache anymore the server's public key during SKE.
826 We do mutual authentication so the proof of posession of
827 private key is done, and if the server is authenticated in
828 conn auth protocol with public key we must have the public
829 key already. Affected file silcd/protocol.c.
831 * Added new global debug variable: silc_debug_hexdump. If
832 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
833 file lib/silcutil/silclog.[ch].
835 * Fixed compilation warning due to char * -> const char *.
836 Affected files lib/silcutil/silcnet.h, and
837 lib/silccore/silcauth.[ch].
839 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
841 * Fixed CMODE command when new channel key was created. If
842 the creation failed the old key was removed. Next time giving
843 same command would crash the server since the old key was
844 freed already. Affected file silcd/command.c.
846 * Fixed the silc_server_announce_get_channels to not crash
847 on reconnect. Affected file silcd/server.c.
849 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
851 * Added silc_log_set_debug_string function to set a regex
852 string to match for debug output. Only the function names,
853 or filenames matching the given debug string is actually
854 printed. This way it is possible to filter out those debug
855 strings that user is not interested in.
857 Fixed a bug in silc_string_regexify.
859 Affected files lib/silcutil/silclog.[ch], and
860 lib/silcutil/unix/silcunixutil.c.
862 * Changed the -d options in both server and Irssi SILC client
863 to take the debug string as argument. Affected files
864 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
866 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
868 * Added silc_hash_babbleprint to create a Bubble Babble
869 Encoded fingerprint. The encoding is developed by Antti
870 Huima (draft-huima-babble-01.txt), and it creates human
871 readable strings out of binary data. Affected file
872 lib/silccrypt/silchash.[ch].
874 * Print the babble print now in addition of fingerprint as well
875 in Irssi SILC client. Affected files are
876 irssi/src/fe-common/silc/module-formats.[ch],
877 irssi/src/fe-common/silc/core/client_ops.c.
879 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
881 * Fixed a security problem found in SKE. The initiator's
882 public key too is now added to the HASH hash value creation
883 which is signed by the responder to create the SIGN value.
884 This will prevent anyone in the middle to lie to the responder
885 about the initiator's public key. If this is done now, the
886 man in the middle will get caught. Updated the protocol
889 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
891 * Better installation directory handling. Configure module
892 paths and other paths automatically to example_silc* files
893 in doc/. A patch by toma.
895 * Fixed compiler warning from MPI library, and from SILC RNG.
898 * Added SILC_SERVER_PID_FILE to define the pid file for server.
899 It can be configured with ./configure. A patch by toma.
901 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
903 * Find correct make to use in prepare-clean. A patch by
904 toma. Affected file prepare-clean.
906 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
908 * Added irssi variables use_auto_addr, auto_bind_ip,
909 auto_bind_port and auto_public_ip.
911 * Changed the interface for silc_client_send_key_agreement
912 in lib/silcclient/silcapi.h
916 irssi/src/silc/core/silc-core.c
918 lib/silcclient/silcapi.h
919 irssi/src/silc/core/silc-channels.c
920 lib/silcclient/client_keyagr.c
923 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
925 * Added silc_pkcs_public_key_compare to compare two
926 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
928 * Check that the client who set the founder mode on the
929 channel is the same client that is giving the founder
930 mode to itself. It is done by comparing the saved public
931 key (it is saved even in the authentication is passphrase).
932 Affected file silcd/command.c.
934 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
936 * Do not process packet for disconnected socket connection.
937 Affected file lib/silccore/silcpacket.c.
939 * Process the DISCONNECT packet through scheduler in the
940 client library. Affected file lib/silcclient/client.c.
942 * Fixed the silc_client_packet_parse to not to increase
943 the packet sequence number if the conn->sock and the
944 current socket connection is not same. This can happen
945 for example during key agreement when the conn includes
946 multiple socket connections (listeners). Affected file
947 lib/silcclient/client.c.
949 * The sender of the file transfer request now provides also
950 the pointer (listener) for the key exchange protocol. If
951 the listener cannot be created then it sends empty key
952 agreement and lets the receiver provide the listener.
954 Added `local_ip' and `local_port' arguments to the
955 silc_client_file_send. If they are provided they are used,
956 if not then it will attempt to find local IP address, if
957 not found or bind fails then the remote client will provide
960 Affected files are lib/silcclient/client_ftp.c and
961 lib/silcclient/silcapi.h.
963 * Extended the FILE SEND command to support defining the
964 local IP and port for key exchange listener. They are
965 optional. Affected file irssi/src/silc/core/silc-servers.c.
967 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
969 * Defined to WHOIS command reply the sending of fingerprint
970 of the client's public key (if the proof of posession of the
971 corresponding private key is verified by the server).
972 Updated to the protocol specification.
974 * Added support of receiving the client's public key's
975 fingerprint in command reply in client library. Affected
976 file is lib/silcclient/command_reply.c, and
977 lib/silcclient/idlist.[ch].
979 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
981 * Do not send over 128 chars long nickname to the server
982 in NICK command. Affected file lib/silcclient/command.c.
984 * Do not send over 256 chars long channel names to the server
985 in JOIN command. Affected file lib/silcclient/command.c.
987 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
989 * Assure that silc_server_close_connection cannot be called
990 twice for same socket context. Affected file is
993 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
995 * Send error message to application if opening file for
996 writing during file transfer fails. Affected file is
997 lib/silcclient/client_ftp.c.
999 Remove all file transfer sessions for a client that we're
1000 removing from ID cache.
1002 Affected file is lib/silcclient/client_ftp.c.
1004 * Fixed silc_net_addr2bin to return correct address. Affected
1005 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1007 * Fixed file transfer session removing on signoff notify.
1008 Affected file irssi/src/silc/core/silc-servers.c.
1010 * Added the SilcClientFileError to be returned in the monitor
1011 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1012 Affected file lib/silcclient/silcapi.h.
1014 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1016 * Fixed a crash in silc_client_ftp_free_sessions and
1017 silc_client_ftp_session_free_client. Affected file
1018 lib/silcclient/client_ftp.c.
1020 * Added `disabled' field in the SilcChannelEntry in the server
1021 to indicate if the server entry is disabled. Affected file
1022 silcd/idlist.h, silcd/command[_reply].c.
1024 * SILC server adds now /var/run/silcd.pid everytime it is
1025 started. Affected file silcd/silcd.c.
1027 * Added silc_server_packet_send_clients to send a packet to
1028 the provided table of client entries. Affected file
1029 silcd/packet_send.[ch].
1031 * Fixed a crash in client resolving in client_prvmsg.c in
1032 client library. Affected file lib/silcclient/client_prvmsg.c.
1034 * Do not actually remove the client directly from ID cache
1035 during SERVER_SIGNOFF, but invalidate it. This way we
1036 preserve the WHOWAS info for the client. Affected file
1037 silcd/server_util.c.
1039 * Fixed SERVER_SIGNOFF notify handling in the server. The
1040 server is now able to process incoming SERVER_SIGNOFF notify
1041 for a server that it doesn't even know about. It will remove
1042 the clients provided in the notify. Affected file
1043 silcd/packet_receive.c.
1045 * Check for partial packet in data queue after every packet that
1046 was found from the queue. Return and wait for more data if
1047 there is partial data in queue. Affected file is
1048 lib/silccore/silcpacket.c.
1050 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1052 * Added SilcClietFileError enum to indicate error in
1053 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1054 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1055 Affected files lib/silcclient/silcapi.h and
1056 lib/silcclient/client_ftp.c.
1058 * Check that newsize in silc_buffer_realloc is larger than
1059 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1061 * Added better monitor of file transfers. It now monitors
1062 key agreement protocol during the file transfer too. Added
1063 error reporting too. Affected files
1064 irssi/src/silc/core/silc-servers.c,
1065 irssi/src/fe-common/silc/module-formats.[ch].
1067 * Wrote a help file for FILE command.
1069 * Added silc_rng_global_get_byte_fast to get not-so-secure
1070 random data as fast as possible. Random data is read from
1071 /dev/urandom if available and from the SILC RNG if not
1072 available. It is used in padding generation. Affected file
1073 lib/silccrypt/silcrng.[ch].
1075 * All packets in client library are now processed synchronously.
1076 Optimized packet processing a lot. Affected file
1077 lib/silcclient/client.c.
1079 * All server connection packets are processing synchronously
1080 now in server, to optimize packet processing. Affected file
1083 * Include files are installed now only in Toolkit distribution
1084 if make install is given. Affected files: all Makefile.am's.
1086 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1088 * Assure that silc_client_notify_by_server_resolve does not
1089 resolve the client information multiple times. If it cannot
1090 be found by the first it cannot be found at all. Affected
1091 file lib/silcclient/client_notify.c.
1093 * Fixed WHOWAS command reply calling. Affected file
1094 lib/silcclient/command_reply.c.
1096 * Removed all references to silc_idlist_get_client from the
1097 Irssi SILC client since that call is internal call used by
1098 the library. The Irssi SILC client will use now client
1099 retrieval functions found in silcapi.h.
1101 * Fixed a bug in resolving nickname info before sending
1102 private message. It used freed memory. Affected file
1103 irssi/src/silc/core/silc-servers.c.
1105 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1107 * Assure my_channels statistics cannot go negative in server.
1108 Affected files silcd/server.c, silcd/server_util.c.
1110 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1114 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

1124 * Added silc_net_localip to return local host's IP address.
1125 Affected file lib/silcutil/silcnet.[ch].
1127 * If key exchange or rekey protocol is active for a connection
1128 parse all packets syncronously since there might be packets
1129 in packet queue that we are not able to process without first
1130 processing packets before them. Affected file silcd/server,
1131 lib/silcclient/client.c.
1133 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1134 whether library should continue processing the packet.
1135 Affected file lib/silccore/silcpacket.h.
1137 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1138 SilcSFTPMonitorData to SFTP server to monitor various

1166 lib/silcutil/silcutil.[ch].
1168 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1170 * Resolve the client info when received private message or
1171 channel message for a client which nickname we don't know.
1172 Affected files lib/silcclient/client_prvmsg.c and
1173 lib/silcclient/client_channel.c.
1175 * Do not crash in /KEY if client is not connected. Affected
1176 file irssi/src/silc/core/silc-channels.c.

1181 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1182 is incomplete and is being resolved, it won't be resolved
1185 Make sure also that USERS command reply does not resolve
1186 twice information. Affected file is
1187 lib/silcclient/command_reply.c.
1189 Make sure that silc_client_get_clients_by_list does not
1190 resolve twice same information.
1192 * Check for valid client->id in the silc_server_free_client_data.
1193 Affected file silcd/server.c.
1195 * Fixed /GETKEY nick@server not to crash if the server entry
1196 is not found. Affected file lib/silcclient/command.c.
1198 * Fixed the silc_server_check_cmode_rights to check the
1199 requested modes correctly. Affected file silcd/command.c.

1203 * Better checks for non-printable chars in nick added.
1204 Affected file silcd/command.c.
1206 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1208 * Call the silc_server_udpate_servers_by_server in the
1209 primary router that comes back online in the backup resuming
1210 protocol. Otherwise it routes packets wrong. Affected file
1211 silcd/server_util.[ch], silcd/server_backup.c.
1213 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1215 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1216 lib/silcutil/silcbuffmt.[ch].
1218 * Redefined the SILC packet header to include the padding
1219 length. Affected file lib/silccore/silcpacket.[ch].
1221 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1222 length for maximum padding up to 128 bytes). Affected
1223 file lib/silccore/silcpacket.h.
1225 * Removed all backwards support for old 0.5.x MAC thingies.
1226 The SILC packet header change makes it impossible to be
1227 backwards compatible.
1229 * Send the ENDING packet with timeout in the backup resuming
1230 protocol. This is to assure that all routers has connected
1231 to the primary router. Affected file silcd/server_backup.c.
1233 * Changed the RNG to take the first IV from random data. It
1234 used to take it from zero actually. Changed the RNG also
1235 to use /dev/urandom during session. /dev/random is used
1236 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1238 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Changed the SILC packet header to have the first two bytes
1241 (the packet length) encrypted. Affected files aroung the
1242 code tree, lib/silccore/silcpacket.[ch]. Removed the
1243 SilcPacketCheckDecrypt callback. It is not needed anymore
1244 since the silc_packet_receive_process will determine now
1245 whether the packet is normal or special.
1247 * Implemented the unidirectional MAC keys. Affected files
1248 lib/silcske/silcske.c, silcd/protocol.c and
1249 lib/silcclient/protocol.c.
1251 * Implemented the packet sequence number to the MAC computation.
1252 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1253 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1254 lib/silcclient/protocol.c.
1256 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1258 * Allow backup router to announce servers. All servers
1259 announced by backup router are added to the global list
1260 automatically. Update hte server's socket to our primary
1261 router also when backup router announces a server.
1262 Affected file silcd/packet_receive.c.
1264 * Do not update the client->router in the function
1265 silc_server_udpate_clients_by_server if the client is on
1266 global list. We might fail to find any specific server
1267 for locally connected clients and local cell clients. They
1268 should still use the `from' and not `to' as client->router.
1269 This fixes backup router resuming protocol. Affected file
1270 silcd/server_util.c.
1272 * Decrease channel statistics count only if the channel
1273 deletion worked. Affected files are silcd/server.c and
1274 silcd/server_util.c.
1276 * Added silc_server_update_servers_by_server to update origin
1277 of all server entries. Used during backup router protocol.
1278 Affected files silcd/server_util.[ch], silcd/server.c. and
1279 silcd/backup_router.c.
1281 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1282 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1283 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1284 lib/silccrypt/silchmac.c.
1286 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1288 * Assure that router cannot reroute the same channel message
1289 to the sender. Affected file silcd/packet_receive.c.
1291 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * Made better checks that the channel message is not sent
1294 to the router it came from. Affected file is
1295 silcd/packet_send.c. Fixed memory leak too.
1297 * Announce informations for incoming router connection, but
1298 only after checking if it is replaced by backup router.
1299 Affected file silcd/packet_receive.c.
1301 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1303 * Fixed the backup resuming protocol to work in multiple
1304 router environment. Affected file silcd/server_backup.c.
1306 * Route packet only to one router in the function
1307 silc_server_packet_send_to_channel. Affected file is
1308 silcd/packet_send.c.
1310 * Fixed silc_server_send_notify_dest to set the broadcast
1311 flag. Fixed the silc_server_send_notify_topic to actually
1312 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1313 Affected file silcd/packet_send.c.
1315 * Changed the SFTP Filesystem interface. Changed the
1316 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1317 the filesystem operation function. The SilcSFTPFilesystem
1318 is now a context that is allocated by all filesystem allocation
1319 functions and it already includes the operations structure
1320 and filesystem specific context. It is given as argument
1321 now to the silc_sftp_server_start. This made the interface
1322 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1323 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1325 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Changed the backup router adding and getting interfaces
1328 in the server. The router that will be replaced by the
1329 specified backup router is now sent as argument. Affected
1330 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1333 * Added silc_net_addr2bin_ne to return the binary form of
1334 the IP address in network byte order. Affected files
1335 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1337 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * Check for existing server ID in silc_server_new_server
1340 and in silc_server_connect_to_router_final and remove the
1341 old entry if it exists. Affected file silcd/packet_receive.c,
1344 * Send the channel message always to only one router, either
1345 in upstream or downstream. Affected file is
1346 silcd/packet_send.c.
1348 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Wrote the definition of the backup resuming protocol to the
1351 protocol specification.
1353 * Removed one redundant channel key generation from normal
1354 server during joining procedure. Removed one redundant
1355 channel key sending from server to router during joining
1356 procedure. Affected file silcd/command.c.
1358 * Made minor bugfixes to the backup router resuming protocol.
1359 Affected file silcd/server_backup.c, server.c.
1361 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Added --disable-asm configuration option. Affected files
1364 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1367 * Implemented the backup resuming protocol that is used to
1368 resume the primary router position in the cell after the
1369 primary router comes back online. Affected files
1370 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1371 and silcd/server_util.[ch].
1373 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1375 * Sleep two (2) seconds after sending QUIT command to server.
1376 Affected file lib/silcclient/command.c.
1378 * Assure that if outgoing data buffer is pending do not force
1379 send any data. Affected file silcd/packet_send.c.
1381 * Assure that if outgoing data buffer is pending do not force
1382 send any data. Affected file lib/silcclient/client.c.
1384 * Implemented the backup router support when the primary router
1385 goes down. The servers and routers can now use the backup
1386 router as new primary router without loosing connectivity.
1388 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1390 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1391 in the server to indicate disabled entry. All data read
1392 from the connection will be ignored and no data is sent
1393 for entry that is disabled. Affected files are
1394 silcd/idlist.h, silcd/server.c.
1396 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * Created SFTP client and server test programs in the
1399 lib/silcsftp/tests directory.
1401 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1403 * Implemented memory filesystem (virtual filesystem) for
1404 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1407 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * Implemented the SFTP (SSH File Transfer Protocol) to the
1410 lib/silcsftp. It includes SFTP client and SFTP server
1413 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1415 * Moved lib/silccore/silcprotocol.[ch] to the
1416 lib/silcutil library.
1418 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1419 take variable argument list pointer as argument. Affected
1420 file lib/silcutil/silcbuffmt.[ch].
1422 * Added silc_buffer_set function that is used to set data
1423 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1424 Affected file lib/silcutil/silcbuffer.h.
1426 * Changed various routines in the core library to use the new
1427 silc_buffer_set instead of allocating new buffer only for
1430 * Added 64-bit value formatting and unformatting support to the
1431 silc_buffer_[un]format routines. Affected file is
1432 lib/silcutil/silcbuffmt.[ch].
1434 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1435 to includes/bitmove.h.
1437 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1439 * Fixed channel user mode saving in client library. Affected
1440 file lib/silcclient/command[_reply].c.
1442 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Defined the file transfer to the SILC Protocol. Added
1445 new packet type SILC_PACKET_FTP and defined File Transfer
1446 Payload. The mandatory file transfer protocol is SFTP
1447 (SSH File Transfer Protocol). Affected file in addition
1448 of the internet draft is lib/silccore/silcpacket.h.
1450 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1451 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1452 is used as part of backup router protocol when the primary
1453 router of the cell is back online and wishes to resume
1454 the position as primary router.
1456 * Redefined the MAC generation keys in the protocol. The
1457 same key is not used anymore in both direction. Both
1458 direction will now use different keys for sending and
1459 receiving. This fixes a potential security flaw. This
1460 change causes incompatibilities in the protocol.
1462 * Redefined also the MAC computation from the packet.
1463 An packet sequence number is now added to the MAC
1464 computation. This prevents possible replay attacks against
1465 the protocol. This change too causes incompatibilities
1468 Added `sequence' field to the SilcPacketContext to hold
1469 the current sequence number for the packet.
1471 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Added `created' field to the SilcIDListData in the file
1474 silcd/idlist.h to indicate the time when the entry was
1477 * Added `created' field to the SilcChannelEntry too. Affected
1478 file silcd/idlist.h.
1480 * Added `creation_time' aguments to all the announcement functions
1481 in the server. If it is provided then only the entries that
1482 was created after the provided time frame are actually
1483 announced. Affected file silcd/server.[ch].
1485 * The protocol says that the Channel ID's IP address must be
1486 based on the router's IP address. Added check for this in
1487 the silc_server_new_channel when processing incoming New Channel
1488 Payload. Affected file silcd/packet_receive.c.
1490 * Print out the correct version with --version in SILC client.
1491 Affected file irssi/src/silc/core/silc-core.c.
1493 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1495 * Fixed WHOWAS command to check for completnes of the client
1496 entry always, not just when the command is coming from client.
1497 Affected file silcd/command.c.
1499 * Added new function silc_server_packet_queue_purge to purge the
1500 outgoing data queue to the network. After the function returns
1501 it is guaranteed that the outgoing packet queue is empty.
1502 Affected file silcd/packet_send.[ch].
1504 * Purge the outgoing packet queue in the rekey protocol's final
1505 callback to assure that all rekey packets go to the network
1506 before quitting the protocol. Affected file silcd/server.c.
1508 * Added silc_client_packet_queue_parse as similar function as
1509 in server to the client library. The affected file is
1510 lib/silcclient/client.c.
1512 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Splitted silcd/server.c and created silcd/server_util.[ch]
1515 for utility functions.
1517 * Added new socket flag SILC_SF_DISABLED to indicate that the
1518 connection is open but nothing can be sent to or received from
1519 the connection. Affected file lib/silcutil/silsockconn.[ch].
1520 The checking for disabled socket is checked in the low level
1521 silc_socket_write and silc_socket_read functions.
1523 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Allow only nicknames and channel names that fits into the
1526 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1528 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1530 * When processing JOIN command reply in server check that if
1531 the channel exists in our global list we'll move it the local
1532 list. Affected file silcd/command_reply.c.
1534 * Fixed the check whether client is joined on the channel already
1535 in JOIN command. Affected file lib/silcclient/command.c.
1537 * Fixed the JOIN command reply to check whether the channel
1538 already exists. Affected file lib/silcclient/command_reply.c.
1540 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1542 * Added silc_ske_status_string to map the SKE error numbers
1543 to readable strings. The affected files are
1544 lib/silcske/silcske[_status].[ch].
1546 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1548 * Do not show the private channels on the WHOIS channel list
1549 as it is not allowed by the protocol. The affected file is
1552 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1554 * Assure that the packet length digged from the actual packet
1555 is something sensible in the silc_packet_decrypt_rest_special
1556 in lib/silccrypt/silcpacket.c.
1558 * Free and NULL the allocated pointer in silc_hmac_alloc if
1559 the HMAC allocation fails. The affected file is
1560 lib/silccrypt/silchmac.c.
1562 * Print the selected security properties to the log files in
1563 the server. Affected file silcd/protocol.c.
1565 * Add SKE's reference counter even if calling the completion
1566 callback manually. Otherwise it goes negative, although it
1567 does not cause any problems. The affected file is
1568 lib/silcske/silcske.c.
1570 * Remove the client entry with short timeout after giving the
1571 KILL command. Affected file lib/silcclient/command.c.
1573 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1574 case all found clients are already disconnected (WHOWAS would
1575 found them) in the server. Affected file silcd/command.c.
1577 * Update the last_receive (time of last data received) to be
1578 updated only when received private or channel message so that
1579 the idle time showed in WHOIS makes more sense.
1581 * Added boolean field `valid' in to the SilcClientEntry in the
1582 client library to indicate whether the entry is valid or not.
1583 This fixes the nickname change bug on channel when changing
1584 the nickname to be same than the old (like nick to Nick) the
1585 nickname formatter doesn't set the new nick anymore to Nick@host.
1586 Affected file lib/silcclient/idlist.[ch].
1588 * Now actually fixed the nickname changing on disconnection.
1589 Added new function silc_change_nick to the Irssi SILC Client.
1590 Affected file irssi/src/silc/core/client_ops.c,
1591 irssi/src/silc/core/silc-nicklist.[ch].
1593 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Check that the public key exists in the GETKEY command before
1596 trying to encode it. Affected file silcd/command.c.
1598 * Print some notifications on received public keys with GETKEY
1599 command in the Irssi SILC Client. Affected files are
1600 irssi/src/fe-common/silc/module-formats.[ch],
1601 irssi/src/silc/core/client_ops.c.
1603 * Use IDENTIFY command to resolve the server information in the
1604 GETKEY command instead of INFO command. Affected file
1605 lib/silcclient/command.c.
1607 * All command reply functions in the client library now calls
1608 the pending command reply callbacks even if an error has
1609 occurred. The server has done this a long time and now it was
1610 time to move the client library to this as well. Now all
1611 errors can be delivered back to the pending command reply
1612 callbacks if necessary. Affected files are
1613 lib/silcclient/command[_reply].[ch].
1615 * Change the nickname on disconnection back to the username
1616 because in reconnect the server will enforce it to it anyway.
1617 Affected file irssi/src/silc/core/silc-servers.c.
1619 * Fixed a config file parsing bug in the Irssi SILC client.
1620 Affected file irssi/src/silc/core/clientconfig.c.
1622 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1624 * When printing the channel mode on JOIN, verify that the
1625 channel key and channel's HMAC are valid. Affected file
1626 irssi/src/silc/core/client_ops.c.
1628 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1630 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1631 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1632 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1634 * Removed channel key rekey task deleting from the function
1635 silc_server_save_channel_key. Affected file silcd/server.c.
1636 Added explicit timeout task context instead that is used to
1637 delete the task if we are registering a new task before the
1638 new task has elapsed.
1640 * When channel key rekey occurs the client library now saves
1641 the old channel key for a short period of time (10 seconds) and
1642 is able to use it in case some is still sending channel
1643 messages encrypted with the old key after the rekey. Affected
1644 file lib/silcclient/[idlist.h|client_channel.c].
1646 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1648 * Added check to the silc_server_new_id_real to not accept
1649 new ID if it is the sender's own ID. Affected file is
1650 silcd/packet_receive.c.
1652 * Assure that we do not announce ourself or the one we've
1653 sending our announcements when we're router and are announcing
1654 servers to our primary router. Affected file silcd/server.c.
1656 * Fixed silc_server_command_identify_check_client to assemble
1657 correct WHOIS packet. It send corrupted WHOIS packet and
1658 caused problem with router to router connections. Affected
1659 file silcd/command.c.
1661 Fixed also silc_server_command_whois_check the same way
1662 as for the IDENTIFY command.
1664 * Added new SilcIDListStatus to the server in the SilcIDListData
1665 structure. The status now includes the current status of
1666 the entry (like registered, resolved etc.). Affected file
1667 silcd/idlist.[ch]. Defined a bunch of different status types
1668 as well. This replaced the old boolean registered field as well.
1670 Added resolve_cmd_ident field to the SilcClientEntry structure
1671 too so that if the entry is for example being resolved so
1672 another command may attach to the same pending command reply
1673 without requiring to resolve the same entry again. This concept
1674 should optimize the WHOIS and the IDENTIFY resolving under
1675 heavy load by taking away unnecessary resolving for entries
1676 that are being resolved already.
1678 Added support for adding multiple pending commands for one
1679 command idenfier. Affected file silcd/command[_reply].[ch].
1681 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1682 before deleting the data. Otherwise the hash table will have
1683 freed data in comparison functions. Affected file is
1684 silcd/command_reply.c.
1686 * Fixed silc_idlist_replace_client_id to add the new entry to
1687 the cache with NULL nickname. Otherwise there will be invalid
1688 memory as the nickname after the nickname is freed. Affected
1689 file silcd/packet_receive.c.
1691 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1692 saved into wrong slots because the previous number of entries
1693 was not taken into account. Affected file silcd/idlist.c.
1694 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1696 * If we are router and we receive JOIN notify to a channel that
1697 does not have any users then notified client is marked as the
1698 channel founder, as it is it. The affected file is
1699 silcd/packet_receive.c
1701 * Added to the extended hash table API's table_del_*ext functions
1702 the destructor as argument too, so that the caller can decide
1703 which destructor to use or whether to use destructor at all.
1704 Affected file lib/silcutil/silchashtable.[ch].
1706 * Fixed ID Cache purging. It actually deleted the entries from
1707 the hash table after the data was freed. The hash table ended
1708 up comparing freed memory. The affected file is
1709 lib/silccore/silcidcache.c.
1711 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1713 * Fixed Irssi SILC client's KILL command's HELP syntax.
1715 * The USERS command now resolves the detailed user information
1716 if the userinfo field is missing. Affected file is
1717 lib/silcclient/command_reply.c.
1719 * Do not print error in silc_file_read if the read file does
1720 not exist. Just silently return NULL. Affected file is
1721 lib/silcutil/silcutil.c.
1723 * Fixed the silc_log_output to not wine about NULL filename
1724 and to not create some bogus " " filename. Affected file is
1725 lib/silcutil/silclog.c.
1727 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Fixed various printing bugs on the user interface in the
1730 Irssi SILC Client. Minor changes that were forgotten from
1733 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Fixed the configure.in.pre and the compilation and distribution
1736 environment to support the new autoconf 2.52. That version is
1737 now required to compile the CVS trunk.
1739 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1741 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1742 to generally parse user@fqdn format strings. Affected file
1743 lib/silcutil/silcutil.c.
1745 * Added nickname_format and nickname_force_format fields to the
1746 SilcClientParams structure. The first one defines the format
1747 for the nicknames that the library will enforce if the receives
1748 multiple same nicknames. The second one is boolean value and
1749 can be used to force the library to always enforce the format
1750 to the nicknames regardles whether there are multiple nicknames
1751 or not. This configurable formatting was employed to flexibly
1752 support accessing multiple nicknames from the user interface.
1753 The userinterface can now set the nicknames to what ever format
1754 they prefer. Affected file lib/silcclient/silcapi.h.
1756 Added function silc_client_nickname_format to the file
1757 lib/silcclient/idlist.c. It performs the nickname formatting.
1759 Added new field `hostname´ to the SilcClientEntry context.
1760 It holds the hostname of the client. Affected file is
1761 lib/silcclient/idlist.h.
1763 * Irssi SILC Client sets the nicknames in nick@hostn format.
1764 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1765 irssi/src/silc/core/silc-core.c.
1767 The WHOIS printing now also shows both the real nickname and
1768 the formatted nickname so that user knows how to access the
1769 user if there are multiple same nicknames cached. Affected
1770 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1771 printing formatting too to take the hostname now as a separate
1772 argument. The Affected file is
1773 irssi/src/fe-common/silc/modules-formats.[ch].
1775 * Changed the silc_client_get_clients_local to accept the formatted
1776 nickname as argument. It accepts the real nickname too but the
1777 formatted nickname can be used to find the true entry from
1778 multiple entries. Affected file lib/silcclient/silcapi.h and
1779 lib/silcclient/idlist.c.
1781 * Added nickname_format_parse field to the SilcClientParams.
1782 It is a callback function provided by the application to parse
1783 the nickname out of the formatted nickname string. The library
1784 calls it to get the nickname from the formatted string. Since
1785 the application generally knows better the format of the nickname
1786 string it parses it instead of the library, even though library
1787 encodes the formatted string. If the callback function is not
1788 provided then the library will use the string as is. The
1789 affected file is lib/silcclient/silcapi.h.
1791 * All the nickname strings passed to the client library in
1792 commands are now expected to be formatted nickname strings.
1793 If the command does not support the formatted nickname string
1794 it will assume that the sent string is the actual nickname.
1795 Affected file lib/silcclient/command.c.
1797 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * Added public key authentication support to OPER and SILCOPER
1800 commands in the client library. Affected file is
1801 lib/silcclient/command.c.
1803 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * Changed the get_auth_methdod client operation to be asynchronous.
1806 It can be async if the application resolves the authentication
1807 method from the server during the negotiation. Added new
1808 SilcGetAuthMeth completion callback that the application will
1809 call after resolving the authentication method.
1811 Added function silc_client_request_authentication_method that
1812 the application can use to resolve the authentication method
1813 from the server. Added also SilcConnectionAuthRequest callback
1814 that the library will call after the server has replied. The
1815 application can call this function if it does not know the
1816 current authentication method.
1818 Affected files are lib/silcclient/client.c and
1819 lib/silcclient/silcapi.h.
1821 * The Irssi SILC client now automatically resolves the authentication
1822 method incase any configuration information is not present (and
1823 currently there never is). The affected file is
1824 irssi/src/silc/core/client_ops.c.
1826 * Fixed public key authentication from the client library.
1827 Affected file lib/silcclient/protocol.c. Changed also the
1828 protocol specification about the public key authentication in
1829 the connection authentication protocol. The actual data to be
1830 signed is now computed with a hash function before signing.
1832 * Fixed the public key authentication from the server as well.
1833 Affected file silcd/protocol.c.
1835 * Removed the mlock()'s from the memory allocation routines.
1836 Affected file lib/silcutil/silcmemory.c. The ./configure does
1837 not check anymore for the mlock(). Affected file is
1840 * Fixed USERS command in server to allow the execution of the
1841 command for private and secret channels if the client sending
1842 the command is on the channel. Affected file silcd/command.c.
1844 * Fixed silc_client_get_clients_local to return the clients
1845 count correctly. It could return wrong value. Affected file
1846 lib/silcclient/idlist.c.
1848 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1850 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1851 types. The assembler optimizations seemed not to like 64-bit
1852 data types. The assmebler optimizations thus are now enabled
1853 also for BSD systems as opposed to only enable them for Linux.
1855 * Do not check for threads at all on BSD systems. Affected
1856 file configure.in.pre.
1858 * Removed -n and -h options from the Irssi SILC Client since
1859 they are not used in silc.
1861 * Fixed the prime generation to assure that the first digit
1862 of the generated random number is not zero since our conversion
1863 routines does not like number strings that starts with zero
1864 digit. If zero digit is seen the random number is regenerated.
1865 This caused some corrupted RSA keys when the zero first digit
1866 was met. Affected file lib/silcmath/silcprimegen.c.
1868 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1870 * Fixed WIN32 configuration in the ./configure script.
1871 Fixed to include xti.h on environments that has it.
1872 Patches by Carsten Ilchmann and andrew.
1874 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1876 * Changed the silc_id_create_client_id to be collision
1877 resistant. It is now assured that there cannot be created
1878 two same client ID's. I suspect that some weird bugs in
1879 the server were actually caused by duplicate Client IDs.
1880 Affected file silcd/serverid.[ch]. A router receiving
1881 new ID now also assures and informs the sending server
1882 if the ID caused collision.
1884 * Changed the silc_id_create_channel_id to also assure that
1885 there are no collisions.
1887 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1889 * Statement about ignoring the Mutual Authentication flag when
1890 performing rekey with PFS was a bit misleading. It is ignored
1891 if it was set in the initial negotiation, it cannot be even
1892 set in the rekey. Fixed in the ke-auth draft. Started the
1893 new versions of the protocol drafts in the doc/.
1895 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1897 * Fixed a bug in silc_client_command_identify_save when saving
1898 new channel information. The channel name was no duplicated
1899 and caused crash on exit. Affected file is
1900 lib/silcclient/command_reply.c.
1902 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Fixed the getkey command handling in the server. Send just
1905 empty OK reply to the sender if the key could not be fetched
1906 (but everything else was ok, like the key just was not available).
1907 Changed the public key parameter to optional in the protocol
1908 specs so that empty OK reply can be sent. Affected file
1911 Added a message to Irssi SILC client to tell to user if the
1912 server did not return a public key.
1914 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Fixed a channel key regeneration bug. It registered new
1917 timeout tasks exponentially until all system resources were
1918 used. Affected file silcd/server.c.
1920 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * Added the SILC Document generator to the scripts/silcdoc.
1923 It can be used to generate the Toolkit Reference Manual out
1924 of the source tree. Internally it will also use the RoboDoc
1925 generator now imported in util/robodoc.
1927 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Added couple of return's in rekey protocol if error orccurred
1930 during the protocol. The execution must be terminated.
1931 Affected file silcd/protocol.c. Also, terminate the protocol
1932 always with timeout.
1934 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * The client's Client ID was created initally from the wrong
1937 nickname (it could have been in format nick@host) in the
1938 silc_server_new_client. Affected file silcd/packet_receive.c
1940 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1942 * Added some SILC_LOG_ERROR's to various error conditions
1943 if client could not be added to ID cache. Affected files
1944 silcd/packet_receive.c and silcd/server.c.
1946 * When client's sock->user_data is freed, NULL also the
1947 client->router and client->connection pointers. Added check
1948 for these pointers being NULL to various places around the
1949 code. Affected file silcd/server.c.
1951 * Added client->data.registered == TRUE checks to various
1952 places around the code to assure that unregistered client's
1953 are not handled when it is not allowed. Affected file
1956 * Added `bool registered' fields to all
1957 silc_idlist_[server|client]_get_* routines to indicate whether
1958 the fetched client needs to be registered or not. Affected
1959 file silcd/idlist.[ch].
1961 * Add your own entry as registered to the ID cache in the
1962 server. Affected file server.c.
1964 * Fixed a bug in silc_server_new_server. The SilcServer was
1965 set as the new server's context instead of SilcServerEntry.
1966 This naturally caused some weird bugs.
1968 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Do not delete the channel rekey task when adding it
1971 for in silc_server_create_channel_key.
1973 * Changed the silc_server_create_channel_key to return
1974 TRUE or FALSE to indicate the success of the channel key
1977 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Fixed MSVC++ project files and added missing files to
1980 Makefiles under win32/.
1982 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1984 * Do not add TCP_NODELAY flag if the operating system
1985 does not have it defined. Affected files are
1986 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1988 * Fixed buffer overflow from Irssi SILC Client. Affected
1989 file irssi/src/fe-common/core/themes.c.
1991 * Fixed double free in client library in the file
1992 lib/silcclient/client.c when disconnecting from server.
1994 * Applied double free patch from cras to Irssi SILC client.
1995 Affected files irssi/src/core/[modules/expandos].c
1997 * Fixed the disconnection handling to Irssi SILC Client.
1998 The application must call silc_client_close_connection
1999 in ops->connect client operation in case of failure of
2000 the connection. Affected file is
2001 irssi/src/silc/core/client_ops.c.
2003 * Do not set sock->protocol to NULL in the function
2004 silc_client_close_connection after executing the protocol's
2005 final callback since the sock might not be valid anymore.
2006 Affected file lib/silcclient/client.c.
2008 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Do not enable SILC_THREADS if the linking with libpthread
2011 did not happen. Affected file configure.in.pre.
2013 * Added notion to protocol specification that server must
2014 verify the sent authentication payload with CMODE when
2015 setting the channel founder key. Implemented it to the
2016 server. Affected file silcd/command.c.
2018 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * Added _EXTRA_DIST SILC distribution variable to the
2021 distributions file. It is used to conditionally add extra
2022 files or directories to the specific distribution. Affected
2023 files ./prepare, Makefile.am.pre and distributions.
2025 Removed the `_' from the start of the distribution names.
2028 * Added README.WIN32 for instructions to compile the Toolkit
2031 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Fixed a double free in disconnection in the server. Affected
2034 file is silcd/server.c.
2036 * Fixed the lib/silcske/groups.c to work now also with GMP
2037 MP library. The string conversion did not work when using
2038 specific base and the base is indicated in the string as well.
2040 * Created win32/ directory which now includes MSVC++ specific
2041 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2042 It will appear only in the toolkit distribution
2044 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Changed the key material distribution function in case when
2047 the hash output is too short. The data is now concatenated
2048 a bit differently than it used to. Made the change to the
2049 SKE protocol specification.
2051 * Added better GMP detection to configure.in.pre. A patch
2054 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2056 * Fixed a minor bug in SKE that might cause some problem on
2057 some platforms. Affected file lib/silcske/silcske.c.
2059 * Added the cookie checking for initiator in the SKE. It checks
2060 that the responder returns the sent cookie unmodified. The
2061 affected file is lib/silcske/silcske.c. Added new SKE
2062 error type INVALID_COOKIE that can be sent during the
2063 negotiation. Fixed some memory leaks as well.
2065 * Added the "invalid cookie" error message to Irssi SILC client's
2068 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * Added `task_max' field to the SilcClientParams to indicate
2071 the maximum tasks the scheduler can handle. If set to zero,
2072 default values are used. Affected file lib/silcclient/silcapi.h.
2074 * Fixed memory leaks in silc_client_close_connection. Affected
2075 file lib/silcclient/client.c.
2077 * Added silc_client_del_client_entry to client library to free
2078 all memory of given client entry. Affected file is
2079 lib/silcclient/idlist.[ch].
2081 * Added new functions silc_client_del_channel and
2082 silc_client_del_server to delete channel and server entries.
2083 Affected file lib/silcclient/[silcapi.h/idlist.c].
2085 * Removed silc_client_del_client_by_id from silcapi.h.
2087 * Fixed the INFO command to return the server's own info
2088 correctly when querying by Server ID. Affected file is
2091 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2093 * Removed the non-blocking settings in WIN32 code in the
2094 silc_sock_[read/write] and added SleepEx instead. Affected
2095 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2096 of input data is now checked with FIONREAD and ioctlsocket.
2098 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2100 * Call silc_schedule_task_del_by_context in the
2101 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2102 Affected file lib/silccore/silcprotocol.c.
2104 * Call silc_protocol_cancel for active protocols in the
2105 silc_server_close_connection if the funtion
2106 silc_server_free_sock_user_data has not been called.
2107 Affected file silcd/server.c.
2109 * Generic tasks cannot be deleted using the del_by_fd
2110 task deleting function since generic tasks does not match
2111 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2113 * Added a notion to SILCOPER help file that the SILCOPER works
2114 only on router server, not on normal server.
2116 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2118 * Added for WIN32 support for the new scheduler as well.
2119 Affected file lib/silcutil/win32/silcwin32schedule.c.
2121 * Fixed the SHA1 implementation to work on various platforms.
2123 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2126 API. It is part of the scheduler now. Everything else is
2127 as previously but some functions has changed their names.
2128 Checkout the lib/silcutil/silcschedule.h for the interface.
2129 Updated all applications to use the new interface. Affected
2130 files are lib/silcutil/silcschedule.[ch].
2132 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Found a bug in the SKE implementation. The HASH value,
2135 specified by the protocol, was not computed correctly. The
2136 public key of the responder was not added to the computation
2137 even though it is mandatory. Affected file lib/silcske/silcske.c.
2138 This unfortunately causes incompatibilities with older
2139 clients and servers.
2141 * Added WIN32 specific network init and uninit functions:
2142 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2143 the Winsock2. Affected file lib/silcutil/silcnet.h and
2144 lib/silcutil/win32/silcwin32net.c.
2146 * Set the socket always to nonblocking mode on WIN32 after
2147 reading data or writing data. Affected file is
2148 lib/silcutil/win32/silcwin32sockconn.c.
2150 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2152 * Fixed various compilation problems under WIN32. Affected
2153 files lib/silcutil/win32/silcwin32thread.c and
2154 lib/silcutil/win32/silcwin32schedule.c.
2156 * Removed all _internal.h #includes from public header
2157 files. Internal headers must never be included from
2160 Removed also the lib/silcske/payload_internal.h file.
2162 * All include files that may be needed (public and some others
2163 included by the public headers) by application developers are
2164 now copied to the ./includes directory. It does not copy any
2165 internal headers. Affected file Makefile.defines.pre and all
2166 Makefile.am's under lib/ and subdirs.
2168 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2170 * Do not change the ~/.silc directory's permissions automatically.
2171 Affected file irssi/src/silc/core/clientutil.c.
2173 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * Do not cancel the protocol in silc_server_close_connection
2176 it might cause recursion. Now cancelled in the function
2177 silc_server_free_sock_user_data. Affected file silcd/server.c.
2179 * Fixed the silc_server_remove_clients_by_server to regenerate
2180 the channel keys correctly finally. Added also new function
2181 silc_server_remove_clients_channels to actually do it.
2182 Affected file silcd/server.c.
2184 * Fixed the silc_server_new_channel to not crash by giving
2185 wrong router to the new channel. Affected file is
2186 silcd/packet_receive.c.
2188 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2191 which is given as argument to the silc_client_alloc now.
2192 It can be used to configure the client and set various parameters
2193 that affect the function of the client.
2195 * The USERS command in server did not check whether the channel
2196 is private or secret. Affected file silcd/command.c.
2198 * Added new argument to the USERS command in protocol specification.
2199 The USERS command now can take the channel name as argument
2200 as well. Added support for this in client and server and
2201 updated the protocol specs.
2203 * Completed the GETKEY command in client. It can be now used
2204 to fetch also servers public key not only some clients.
2205 Affected files lib/silcclient/command[_reply].c.
2207 * Added silc_client_get_server to return server entry by the
2208 server name. Affected files lib/silcclient/silcapi.h and
2211 * Redefined the IDENTIFY command in protocol specification to be
2212 more generic. It now can be used to query information about
2213 any entity in the SILC Network, including clients, servers and
2214 channels. The query may be based either the entity's name
2215 or the ID. Added support for this in both client and server.
2217 Affected files silcd/command.c and lib/silcclient/command.c
2218 and command_reply.c.
2220 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2221 the _from_client and _from_server functions. Affected file
2224 * Added silc_client_get_channel_by_id_resolve to the file
2225 lib/silcclient/silcapi.h to resolve channel information by
2226 its ID. Added also silc_client_get_channel_by_id that
2227 does not resolve it from the server.
2229 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Added SilcServerEntry context into the client library
2232 to represent one server. The INFO command now allocates
2233 these to save the resolved server info. For now on the
2234 client library will also keep information about servers,
2235 connected and resolved with INFO.
2237 The INFO command now allocates the SilcServerEntry context
2238 and saves the server info there. The COMMAND_REPLY in
2239 the INFO now returns the parameters to application in
2240 same order as defined in the protocol specification.
2242 The entries are cached in the client->server_cache.
2244 * The INFO command is now issued after received the Client ID
2245 from the server. Affected file lib/silcclient/client.c.
2247 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2248 to the application as the mode changer might be server.
2249 It is guaranteed that NULL is not returned anymore to the
2250 application. Affected file lib/silcclient/client_notify.c.
2252 The ID Type is now also passed to the application so that
2253 it can check whether the returned entry is SilcClientEntry
2256 Added new function silc_client_get_server_by_id to return
2257 the server entry by ID. Affected files are the
2258 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2260 * Do not create the channel in the Irssi SILC Client when issuing
2261 the JOIN command but when received the sucessful JOIN command
2262 reply. Otherwise the channel might get created even though we
2263 could not join it. The Affected file is
2264 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2266 * Fixed a channel joining bug in router. The router must also
2267 check the channel modes, invite and ban lists etc. when serving
2268 the JOIN command sent by normal server. Affected file is
2269 silcd/command.c. The router now resolves the client's
2270 information from the server who sent the JOIN command if it
2271 does not know it, and processes the JOIN command only after
2274 * Changed the SilcCommandCb to take new argument; void *context2.
2275 Affected file lib/silccore/silccommand.h
2277 The second argument in the command callbacks in the server now
2278 includes the SilcServerCommandReplyContext if the command was
2279 called as pending command callback from the command reply.
2280 Otherwise it is NULL. When called as pending the status of the
2281 command reply will be checked and if it was erronous the
2282 error will be sent to the original sender of the command.
2283 This way the client always receives the error messages even
2284 though the server was actually the one who received the error
2285 when it resent the command to router, for example. Affected
2286 files silcd/command[_reply].[ch].
2288 * Fixed sending WHOWAS command's error message to client if
2289 the requested client could not be found. It was missing.
2292 * Changed the CMODE and CUMODE commands reply arguments in the
2293 protocol specification. The Channel ID is now sent in both
2294 of the commands to identify the channel. Implemented this
2295 new feature to the client and server. Affected files
2296 lib/silcclient/command_reply.c and silcd/command.c.
2298 * Made better checks for invite and ban lists in the JOIN
2299 command in server. Affected file silcd/command.c.
2301 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * The server now performs the incoming host IP/DNS lookup
2304 using the silc_socket_host_lookup and thus does not block
2305 the server anymore. Affected file silcd/server.c.
2307 * Completed the multi-thread support for SILC Scheduler in
2308 the lib/silcutil/silcschedule.c.
2310 * Fixed the configure.in.pre to detect the pthread correctly
2313 * Fixed a deadlock in silc_task_queue_wakeup in the file
2314 lib/silcutil/silctask.c.
2316 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2318 * Added new function silc_schedule_wakeup that is used in
2319 multi-threaded environment to wakeup the main thread's
2320 schduler. It needs to be used when a thread adds a new task
2321 or removes a task from task queues. After waking up, the
2322 scheduler will detect the task queue changes. If threads
2323 support is not compiled in this function has no effect.
2324 Implemented the wakeup mechanism to both Unix and WIN32
2325 systems. Affected files are lib/silcutil/silcschedule.[ch],
2326 lib/silcutil/unix/silcunixschedule.c and the
2327 lib/silcutil/win32/silcwin32schedule.c.
2329 * Added new function silc_task_queue_wakeup to wakeup the
2330 scheduler by the specified task queue. Affected file
2331 lib/silcutil/silctask.[ch].
2333 * The silc_socket_host_lookup_start now wakes up the scheduler
2334 after adding the timeout task. Affected file is
2335 lib/silcutil/silcsockconn.c.
2337 * The silc_socket_host_lookup is synchronous now if the threads
2338 support is not compiled in. However, the callback is still
2339 called asyncronously through the scheduler, anyway. Affected
2340 file lib/silcutil/silcsockconn.c.
2342 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Added new function silc_socket_host_lookup to perform
2345 asynchronous IP and FQDN lookups for the socket connection.
2346 Affected files lib/silcutil/silcsockconn.[ch].
2348 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2350 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2351 that may or may not compile the mutex support in.
2353 Changed the silc_mutex_alloc interface. It allocates the
2354 mutex now to the sent pointer and returns TRUE or FALSE.
2356 Affected file lib/silcutil/silcmutex.h.
2358 * Wrote the SILC Task Queue interface to support multi-threads.
2359 Affected file lib/silcutil/silctask.[ch].
2361 * Wrote the SILC Scheduler to support multi-threads. Affected
2362 file lib/silcutil/silcschedule.c.
2364 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2367 in lib/silcutil/win32/.
2369 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * Defined SILC Mutex API and SILC Thread API and implemented
2372 them for Unix. Affected files are
2373 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2374 lib/silcutil/unix/silcunixmutex.c and
2375 lib/silcutil/unix/silcunixthread.c.
2377 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2379 * Fixed the silc_server_remove_clients_by_server's channel
2380 key re-generation. The hash table handling was incorrect
2381 and would not work with many channels. Affected file is
2384 * Fixed some memory leaks around the server code.
2386 * Rewrote the silc_server_get_users_on_channel to support IPv6
2387 based Client ID's. Affected file silcd/server.c.
2389 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2390 specification. However, a separate document must be written
2391 to define the detailed signing procedure and the payload
2392 associated with the flag. Defined the flag to the
2393 lib/silccore/silcchannel.h as well.
2395 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2397 * Changed the dynamic tables to static size tables in the
2398 lib/silccrypt/silchmac.c.
2400 * Removed GCC dependencies from the code. A patch by cras.
2402 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * Do not show the error "Error receiving packet bla bla"
2405 in server if it really was not an error (-2 means that reading
2406 is pending). Affected file silcd/server.c.
2408 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2410 * Fixed a possible crash in silc_server_remove_clients_by_server
2411 in silcd/server.c. Fixed there also some memory leaks.
2413 * Fixed the silc_idlist_replace_client_id. It could replace
2414 wrong key in the hash table. Affected file silcd/idlist.c.
2416 * Do not check whether there are global users on the channel
2417 if the channel->global_users is FALSE. Affected functions
2418 silc_server_remove_from_one_channel and
2419 silc_server_remove_from_channels in silcd/server.c. Also,
2420 do not check if the removed client is local as we can be
2421 sure that global client was not removed from the channel
2422 and checking for global users is not needed.
2424 * The silc_server_remove_clients_by_server now re-generates
2425 the channel keys correctly for those channels that had
2426 clients removed from them. Affected file silcd/server.c.
2428 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Found the reason of random crashes in the server. We weren't
2431 ignoring the SIGPIPE signal (which can be sent in write())
2432 and it crashed the server. Affected file silcd/silcd.c.
2434 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Assure that sock->user_data is not NULL in the function
2437 silc_server_packet_send in silcd/packet_send.c.
2439 * Disconnect the remote connection if it could not be added
2440 to any ID lists in the server. The affected file is
2443 * Check in silc_server_packet_send[_real/dest] that the
2444 socket is not disconnecting and ignore the data if it is.
2445 Affected file silcd/packet_send.c.
2447 * Define inline to __inline on native WIN32 compilation.
2448 Affected file includes/silcwin32.h.
2450 * Added some explicit type casts for inline code since MSVC
2451 require them. Affected files lib/silcutil/silcbuffer.h,
2452 lib/trq/silcdlist.h and lib/trq/silclist.h.
2454 * Print warning in log files from now on if the packet
2455 decryption fails. Affected file silcd/server.c.
2457 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2459 * Changed the `say' client operation's interface to accept
2460 new `type' argument to indicate the type of the message sent
2461 by the library. The application may filter the library's
2462 messages according the type. The affected file is the
2463 lib/silcclient/silcapi.h.
2465 * Added two new functions to lib/silcclient/silcapi.h:
2466 silc_client_del_client and silc_client_del_client_by_id.
2467 Affected file lib/silcclient/idlist.c.
2469 * Moved the clientincludes.h from includes/ to silc/ and
2470 serverincludes.h from includes/ to silcd/.
2472 * The modes for the CMODE and CUMODE are now passed as
2473 uint32 for application with COMMAND_REPLY. The affected
2474 file is lib/silcclient/command_reply.c.
2476 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * /WHOIS without arguments shows client's own information.
2479 Affected file lib/silcclient/command.c.
2481 * Changed PING to not accept any arguments. The specs
2482 says that client can ping only the connected server so
2483 requiring an argument is not needed. Affected file is
2484 lib/silcclient/command.c.
2486 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2488 * Fixed a fatal bug in private message sending and reception
2489 encryption and decryption when using private message keys.
2490 The implementation was incorrect and did not follow the
2491 specification. It causd that some of the message were
2492 lost since it did not use the sending and receiving keys
2493 as the protocol suggests. This has been fixed and will cause
2494 incompatibilities with older clients when sending private
2495 message encrypted with private message keys. Affected files
2496 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2497 and various other in Irssi SILC Client.
2499 Added `responder' boolean argument to the functions
2500 silc_client_add_private_message_key[_ske] to indicate when
2501 the key is added as responder or initiator of the key
2504 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * Removed the silc_ske_check_version function and created
2507 a SilcSKECheckVersion callback. Added also a function
2508 silc_ske_set_callbacks that is now used to set all SKE
2509 callbacks. The callback functions are not given to
2510 the SKE functions anymore, but this function is used to
2513 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2515 * Added `silc_version' argument to the silc_client_alloc
2516 to define the version of the application for the library.
2517 The library will use the version string to compare it
2518 against the remote host's (usually a server) version
2519 string. Affected file lib/silcclient/silcapi.h
2521 * Added the KE protocol context to Key Agreement context
2522 in client library so that we can abort the SKE if it
2523 is in process when we get timeout. Affected file is
2524 lib/silcclient/client_keyagr.c.
2526 * Do not resolve the client ID forever if it returns in the
2527 first time that such client does not exist. This was done
2528 for example with private message. Affected file is
2529 lib/silcclient/client_prvmsg.c.
2531 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Do not add regex.h for WIN32. The affected file
2534 includes/silcincludes.h.
2536 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2537 not work yet 100%. It generates the DLL's automatically
2538 when compiling with --with-win32 under cygwin.
2540 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2542 * lib/contrib/regex.c is not compiled on WIN32.
2544 * Added silc_net_get_socket_opt function to the
2545 lib/silcutil/silcnet.h.
2547 * Added includes/silcwin32.h for WIN32 specific includes
2550 * Do not use ptime structure or any of the posix process
2551 functions on WIN32 in lib/silccrypt/silrng.c.
2553 * Added silc_gettimeofday to provide generic function
2554 for struct timeval on all platforms. Added the function
2555 to lib/silcutil/silcutil.h.
2557 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2559 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2560 library as they clearly belong there. As a plus side we
2561 can make the actual socket connection routines platform
2564 Added also new generic function silc_socket_read and
2565 silc_socket_write (that used to be silc_packet_[read/write].
2566 The implementation of these are platform specific.
2568 * Added WIN32 specific routines of silc_socket_[read/write]
2569 to lib/silcutil/win32/silcwin32sockconn.c.
2571 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2573 * Added preliminary support for native WIN32 compilation under
2574 cygwin (using the -mno-cygwin option for GCC) to the
2575 ./configure.in.pre. The --with-win32 now prepares the
2576 compilation for native WIN32.
2578 * Rewrote the SILC Scheduler interface in the file
2579 lib/silcutil/silcschedule.h. The scheduler is now context
2580 based and does not have anymore any global static scheduler.
2581 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2582 and created lib/silcutil/win32 directory for WIN32 based
2585 * Added Unix specific network routines to the
2586 lib/silcutil/unix/silcunixnet.c and the old
2587 lib/silcutil/silcnet.c includes now only generic routines.
2589 Added WIN32 specific network routines to the
2590 lib/silcutil/win32/silcwin32net.c.
2592 * Added Unix specific utility functions from the
2593 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2595 * Added WIN32 SILC Scheduler to the file
2596 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2599 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Do not handle JOIN notify in the server if the target client
2602 is not registered (idata->registered == FALSE). The affected
2603 file is silcd/packet_receive.c.
2605 * Update the nickrec->founder in event_cumode in the Irssi SILC
2606 client. Affected file irssi/src/silc/core/silc-channels.c.
2608 * Fixed the CUMODE_CHANGE notify handling in the server when
2609 server and router are announcing their clients on channels.
2610 Now the mode changes are saved and notified correctly. The
2611 affected file is /silcd/packet_receive.c.
2613 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2614 They really did not replace the cache entry in the ID Cache.
2615 Now they do that. Affected file silcd/idlist.c.
2617 * Fixed the KICK notify handling in the Irssi SILC client to
2618 update the channel records so that the kicked client does not
2619 appear to be on the channel. The affected file is
2620 irssi/src/silc/core/silc-channels.c.
2622 * Always update the conn->current_channel when executing command
2623 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2625 * Fixed the KILL notify handling in Irssi SILC client to remove
2626 the killed client on all channels.
2628 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2630 * Fixed the silc_parse_command_line to remove extra spaces
2631 from the start and end of the arguments. Affected file is
2632 lib/silcutil/silcutil.c.
2634 * Cancel and free any active protocol in the function
2635 silc_server_close_connection. Affected file silcd/server.c.
2637 * Cancel and free any active protocol in the function
2638 silc_client_close_connction. Affected file is
2639 lib/silcclient/client.c.
2641 * Do not execute the KILL command for clients that are in
2642 history (ie. they are not in the network). Affected file is
2645 * Fixed KILL notify handling, client does not crash anymore.
2646 Affected file irssi/src/silc/core/silc-channels.c.
2648 * Reduced the default packet buffer size from 2048 to 1024 in
2649 lib/silccore/silcpacket.c.
2651 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2652 counter to the SKE context that is incresed when the SKE library
2653 performs async operation outside the library. If the outside
2654 process frees the SKE context and FREED status will be set
2655 and the library will detect after the sync operation that the
2656 libary is freed. The affected files are
2657 lib/silcske/silcske[_status].[ch].
2659 * Resolve the client entry information in the function
2660 silc_client_channel_message to assure that NULL pointer is not
2661 passed as client entry to the application. */
2663 * Fixed the task timeout calculation to assure that there is
2664 never negative timeouts. The affected file is
2665 lib/silcutil/silcschedule.c.
2667 * Fixed the channel user mode notification sending in server.
2668 It was sent point-to-point to the router (or to server by router)
2669 but it needs to be destined to a channel. The routines now
2670 supports sending the channel user mode notifys to the channels
2671 when announcing clients and channels. Affected files are
2672 silcd/server.c and silcd/packet_receive.c.
2674 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2675 It did not actually replace the old channel entry in the cache.
2676 Affected file lib/silcclient/client_notify.c.
2678 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2680 * Fixed a possible crash in silc_packet_send_prepare. It now
2681 assures always that there is enough space in the buffer and
2682 at the tail area of the buffer (for MAC).
2684 Fixed the inbound buffer reallocation in silc_packet_read.
2685 It was old code and did not handle the reallocation correctly.
2688 The affected file is lib/silccore/silcpacket.c.
2690 * Fixed buffer overflow in silc_parse_nickname in the file
2691 lib/silcutil/silcutil.c.
2693 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2695 * make install generates new server keys only if there is not
2698 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2700 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2701 Added check that if the NOREPLY is set then we will not send
2702 the away message. This avoids infinite loop of away messages
2703 if both clients are away. The affected file is
2704 lib/silcclient/client_prvmsg.c.
2706 * Fixed client crash if /NICK was given without arguments.
2707 Affected file lib/silcclient/command.c.
2709 * Server does not send the invite list in INVITE command back
2710 to the client if the list was not altered. Added this notion
2711 to the protocol spec as well. Affected file silcd/command.c.
2713 Fixed possible crash in INVITE command by checking the
2714 value of silc_server_get_client_route command.
2716 * Fixed the INVITE notify type handling. The arguments are now
2717 taken in correct order and client does not crash. The affected
2718 file is irssi/src/silc/core/silc-channels.c.
2720 Removed the "Inviting xxx to channel" message from the
2721 client library away and let the application handle it.
2722 Affected file lib/silcclient/command.c. Added that message
2723 to Irssi SILC client's message formats.
2725 * Fixed CMODE command crash in client. It now checks the
2726 amount of arguments correctly and does not crash. The affected
2727 file is lib/silcclient/command.c.
2729 * Do not create new channel automatically in silc_channels_join
2730 but check whether the channel by that name already exists.
2731 Affected file irssi/silc/core/silc-channels.c.
2733 * Do not send the SERVER_SIGNOFF to router if the disconnected
2734 entity was the router. Affected file silcd/server.c.
2736 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2737 SILC client as it was missing from there.
2739 Added the handling of the KICK notify to the Irssi SILC client
2740 as it was missing. Added "you have been kicked" message to
2741 Irssi SILC client's message modules formats.
2743 Added the handing of the KILL notify to the Irssi SILC client
2744 as it was missing. Added the kill message module formats
2747 The affected file is irssi/src/silc/core/silc-channels.c.
2749 * The router did not save the channel mode the server announced.
2750 Affected file silcd/packet_receive.c.
2752 * Fixed a possible crash in INFO command in server. If the
2753 server did not provide the server info it crashed. Affected
2754 file silcd/command.c.
2756 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Fixed the GETKEY command in the server to check also the
2759 global list. Otherwise the GETKEY would not work correctly
2760 in normal SILC server. Affected file silcd/command.c.
2762 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2764 * Fixed GETKEY crash, it crashed if the command did not succseed.
2766 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2769 is now real and not just an macro interface to GMP.
2771 Removed the entire GMP from the source tree and imported new
2772 NSS MPI library instead. Reason for removing GMP is that it is
2773 extremely large and compiles extremely slow. The NSS MPI
2774 is only a few files and compiles in less than 10 seconds.
2775 The speed is also about the same as GMP. The MPI is imported
2776 to lib/silcmath/mpi.
2778 If the system has GMP installed we will still use the GMP.
2779 If it is not then the NSS MPI will be compiled.
2781 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2783 * Merged a long nickname (127 characters long) crash bugfix from
2784 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2786 * Merged a freed memory reference bugfix from Irssi CVS tree.
2787 Affected file irssi/src/core/commands.c.
2789 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Added the server's public key sving and verification to the
2792 server when performing the SKE. This was missing and the
2793 remote server's (or router's) public key was accepted without
2794 checking whether we have it previously or trust it at all.
2795 Affected file silcd/protocol.c.
2797 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Check in the silc_server_timeout_remote if protocol is active
2800 and make sure that the protocol's final callback is called so
2801 that all memory if freed. Affected file silcd/server.c.
2803 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * silc_server_whois_send_reply crashed the server if the nickname
2806 was 127 characters long. Affected file silcd/command.c.
2808 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2810 * Added sanity check to the silc_server_new_client. If the hostname
2811 is provided inside username then check that the provided hostname
2812 really is the same as the resolved one. If the hostname was not
2813 resolved then check it from the public key. Affected file is
2814 silcd/packet_receive.c.
2816 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2817 if the server disconnected us and the connection is not valid
2818 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2820 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2821 the library to the lib/silcutil/silcutil.[ch].
2823 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2825 * Close log file after open. Affected file
2826 lib/silcutil/silclog.c.
2828 * Check whether sock == NULL in silc_client_send_packet and return
2829 if it is. Affected file lib/silcclient/silcclient.c.
2831 * Check rec->entry == NULL in the Irssi SILC Client before
2832 sending the channel message. Affecte file is
2833 irssi/src/silc/core/silc-servers.c.
2835 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2837 * Merged a splitted window bugfix from Irssi CVS tree. The
2838 affected file is irssi/src/fe-text/textbuffer-view.c.
2840 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2841 It did not print nickname.
2843 * Improved the distributions system a bit.
2845 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2848 irssi/src/fe-text/gui-window.c.
2850 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2851 to in-active server. The affected file is
2852 irssi/src/silc/core/client_ops.c.
2854 * Resolve the client in USERS command reply if the entry does
2855 not have username resolved. The affected file is
2856 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2857 command to WHOIS command to really resolve stuff. The USERS
2858 is not used any more in any critical section so WHOIS can
2859 be used even though it might be slower than IDENTIFY.
2861 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2864 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * Changed the protocol API a bit more consistent in the
2867 lib/silccore/silcprotocol.[ch].
2869 * Changed the following headers to ROBODoc format:
2871 lib/silccore/silcpayload.h
2872 lib/silccore/silcprotocol.h
2873 lib/silccore/silcsockconn.h
2875 All core library headers are now formatted.
2877 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * Fixed a bug in Irssi SILC client; do not show that you are
2880 server/router operator if you really are not. Affected file is
2881 irssi/src/silc/core/client_ops.c.
2883 * Renamed silc_command_free_payload to silc_command_payload_free.
2884 Affected file lib/silccore/silccommand.h
2886 * Added silcmath.h to include the prototoypes of various routines
2887 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2890 * Changed the following headers to ROBODoc format:
2892 lib/silccore/silcchannel.h
2893 lib/silccore/silccommand.h
2894 lib/silccore/silcid.h
2895 lib/silccore/silcidcache.h
2896 lib/silccore/silcmode.h
2897 lib/silccore/silcnotify.h
2898 lib/silccore/silcpacket.h
2899 lib/silcmath/silcmath.h
2901 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Added checking to the server code not to start the server if
2904 ciphers and stuff are not configured properly. Affected files
2905 silcd/serverconfig.[h] and silcd/server.c.
2907 * Changed the layout of the header files of the public interfaces
2908 in the SILC libraries. The new layout supports ROBODoc
2909 documentation tool (and some others) so that it is easy to create
2910 a library reference manual. All the other headers and source
2911 code must still follow the CodingStyle document. Also source
2912 code must not include these ROBODoc stuffs, only the headers.
2913 Furthermore, all public interface headers must now be named
2914 by using `silc' prefix, example: silcapi.h, silccipher.h.
2915 Some files were renamed due to this. All the other headers
2916 must not be used as public interfaces. I will update the
2917 CodingStyle document later. Changed following headers, so far:
2919 lib/silcclient/silcapi.h
2920 lib/silccore/silcauth.h
2921 lib/silccore/silcprivate.h
2922 lib/silccrypt/silcdh.h
2924 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * Removed silc_client_packet_send_flush from the client library
2929 as it is not needed. Affected file lib/silcclient/client.[ch].
2931 * Added printing of message of unresolved authentication method
2932 to the Irssi SILC client. Added it to the module formats.
2933 Removed the same message from the client library.
2935 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Added new distribution feature, DISTLABEL. Every distribution
2938 can define own preprocessor label that can be used in the
2939 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2940 file distributions, acconfig.h.pre and prepare.
2942 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Added Makefile.defines_int to include the actual definitions
2945 for Makefile.defines.in. Tested the new distribution system,
2946 created distributions and tested installation.
2948 * Added AWAY message printing to the Irssi SILC client. Added
2949 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2951 * Added SCONNECT command to call the SILC's CONNECT command.
2952 Cannot use CONNECT directly since Irssi uses that internally.
2953 Affected file irssi/src/silc/core/silc-servers.c.
2955 Added ACTION local command. It is same as ME command but takes
2956 the channel as mandatory argument.
2958 Rewrote some of the Irssi's help files to suite for SILC
2961 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Added Makefile.defines[.in] that should for now on be included
2964 in all Makefile.am file in the source tree. That file includes
2965 all common compilation definitions for SILC source tree.
2967 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * Minor changes to the ./prepare script to change the package
2970 name according the distribution name to the configure.in.
2972 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Created new distribution system. Added file `distributions'
2975 that defines all the distributions that can be created out of
2976 the SILC source tree. The ./prepare script now reads that
2977 file to determine how to prepare the distributions. The
2978 first argument to the ./prepare is the name of the distribution
2979 and second is the version of the distribution. If given
2980 without arguments it creates the default (toolkit) distribution
2981 with the default version (defined in ./prepare).
2983 All Makefile.am files that are subject to the distributions
2984 are now named as Makefile.am.pre. These are ./Makefile.am
2985 and lib/Makefile.am. Others may be changed later.
2987 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * Added invite list, ban list, some key management and connection
2990 error message printing to module formats in the Irssi SILC client.
2992 * Added new silc_client_set_away_message to set the away message
2993 that is back to the person who sent private message. The
2994 affected file lib/silcclient/silcapi.h and the
2995 lib/silcclient/client_prvmsg.c.
2997 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Fixed the private message sending in the Irssi SILC client,
3000 added local command KEY to the Irssi SILC client.
3002 Added key management and key agreement message formats to the
3003 irssi/src/fe-common/silc/module-formats.[ch].
3005 Added USERS (alias WHO) printing, server/router operator
3006 indication and LIST command printing to the module formats.
3008 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3010 * Fixed channel joining notify handling, cumode notify handling
3011 from Irssi SILC client.
3013 * Added SILC specific module-formats to the Irssi SILC client so
3014 that SILC specific message hilighting, colors etc is possible.
3015 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3017 Added channel mode, channel user mode, actions, notices,
3018 whois and whowas printing to the the module-formats.c.
3020 * Fixed a bug in channel deletion in the server. The channel
3021 is not left to the cache even if the channel founder auth mode
3022 is set when there are no users anymore on the channel. Affected
3023 file silcd/server.c.
3025 * The silc_net_localhost now resolves the entire hostname including
3026 the domain name. Affected file lib/silcutil/silcnet.c.
3028 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Changed the ask_passphrase client operation to be ascynchronous.
3031 It has now a completion callback and a context that the
3032 application must call after it has got the passphrase from
3033 the user. Affected files lib/silcclient/silcapi.h,
3034 lib/silcclient/protocol.c, lib/silcclient/command.c and
3037 Added SilcAskPassphrase callback that the application calls
3038 to deliver the passphrase to the library.
3040 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3041 The public key verification and especially a certificate
3042 verification is asynchronous procedure.
3044 Added new SILC_SKE_STATUS_PENDING status to indicate the
3045 request is pending and a callback will be called to finalize
3048 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3049 indicate that remote end did not send its public key (or
3050 certificate), even though we require it. Added check for this
3051 condition in the SKE. This was a security bug, now fixed.
3053 Defined new SilcSKEVerifyCbCompletion callback that is called
3054 when the verification process is completed.
3056 The affected files lib/silcske/silcske_status.h and
3057 lib/silcske/silcske.[ch].
3059 * Changed the verify_public_key client operation to be async
3060 as well. Defined SilcVerifyPublicKey callback that is used to
3061 indicate the success of the public key verification process.
3063 Changed the server and client to use the new async client
3066 * Changed the Irssi SILC client's internal scheduler to be called
3067 twice as many times as it used to be. As a result the client
3068 should be a bit faster now. Affected file is
3069 irssi/src/silc/core/silc-core.c.
3071 * Added support to Irssi SILC client of asynchronous public key
3072 verification and passphrase inquiry. Affected file is
3073 irssi/src/silc/core/silc-core.c.
3075 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Do not say "You have left channel %s" in client library.
3078 Moved it to the application. Affected files are
3079 lib/silcclient/command.c and silc/client_ops.c.
3081 * Fixed silc_client_get_clients. Command context was not
3082 duplicated and was freed memory in the callback. Affected
3083 file lib/silcclient/idlist.c.
3085 * Do not say "you are now talking..." on JOIN command in the
3086 client library. The appliation must handle it.
3088 * Do not say ".. changed topic to" in command reply in the
3089 client libary. The application must handle it.
3091 * Fixed TOPIC command sending in the client library.
3093 * Fixed a memory leak in silc_client_command_free in the file
3094 lib/silcclient/command.c.
3096 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Imported a modified version of Irssi client to the source tree.
3099 The Irssi will be used to create a new client called
3100 Irssi SILC. Imported to irssi/.
3102 Added silc_core_init_finish function to the Irssi. Affected
3103 file irssi/configure.in.
3105 A lot changes in the Makefile.ams around the irssi tree.
3107 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3109 * Do not rehash if the new size is same as the old size of the
3110 hash table, in the silc_hash_table_rehash*. The affected file
3111 lib/silcutil/silchashtable.c.
3113 * Replaced hash_table_del_by_context calls from the server
3114 (when channel->user_list and client->channels) to the
3115 hash_table_del as it is sufficient and faster.
3117 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Added silc_hash_table_list, silc_hash_table_get and the
3120 SilcHashTableList structure to provide an alternative way to
3121 traverse the hash table. The affected files are
3122 lib/silcutil/silchashtable.[ch].
3124 * Changed the server's idlist routines to use the hash table
3125 routines to optimize the code.
3127 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Replaced the client entry's `channel' list and channel entry's
3130 `user_list' list to hash tables for optimized lookup. Changed
3131 the code to use the hash table interface around the code.
3132 Affected file lib/silcd/idlist.[ch].
3134 * Added `auto_rehash' boolean argument to the function
3135 silc_hash_table_alloc to indicate whether the hash table should
3136 auto-rehash when it thinks is appropriate time. It will
3137 increase the hash table size if the there is twice as much
3138 entries in the table than the size of the table, and will
3139 decrease the size if there are twice as less entries than
3140 the size of the table.
3142 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3146 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * silc_idcache_purge_by_context deletes the entry now by context
3149 as it is supposed to do. Affected file lib/silccore/idcache.c.
3151 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3152 client is not anymore valid (WHOWAS givens the info) and not
3153 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3155 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Removed the `data' and `data_len' arguments from the ID Cache
3158 interfaces and added `name' argument. ID Cache does not handle
3159 anymore the binary data only a names associated with given ID.
3161 * When hashing a Client ID with silc_hash_id the entire ID is
3162 not hashed anymore, instead only the hash of the Client ID is
3163 hashed. This way we can access the Client ID from the cache
3164 with Client ID but with the hash of the ID (which is a hash of
3165 the nickname) as well without any difference in performance.
3167 Added also silc_idcache_find_by_id_one_ext to do one on one
3168 searching when we have the actual ID. Added also function
3169 silc_hash_client_id_compare. The affected files are
3170 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3172 * When hashing the name associated with a ID it is always done
3173 in lowercase. This way we can access the cache without worrying
3174 about case-sensitivity, even though, for example nicknames are
3177 * Fixed a bug in server with channel message sending. It put
3178 wrong ID type as destination ID. The affected file
3179 silcd/packet_send.c.
3181 * silc_idcache_del_by_context now deletes from all hash tables
3182 by context. Affected file lib/silccore/idcache.c.
3184 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Changed the client library to use the new ID Cache interface.
3187 Changes around the source tree.
3189 * Added silc_hash_table_rehash_ext to rehash with specific
3190 hash function. Affected file lib/silcutil/silchashtable.[ch].
3192 * Added silc_hash_string_compare to compare two strings in the
3193 hash table. Affected file lib/silcutil/silcutil.[ch].
3195 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * Added new function silc_idcache_del_by_context into the
3198 lib/silccore/idcache.[ch].
3200 * Changed the server's ID list routines to use the new ID Cache
3201 interface. Changes around the source tree.
3203 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * Added silc_hash_table_del[_by_context]_ext functions in to the
3206 lib/silcutil/silchashtable.[ch].
3208 Removed silc_hash_table_find_all* routines and added new
3209 silc_hash_table_find_foreach to replace them.
3211 Added silc_hash_table_replace_ext function as extended
3212 replacing function. Separated the simple hash table interface
3213 from the extended hash table interface in the file
3214 lib/silcutil/silchashtable.h.
3216 * Fixed minor bugs and changed it to use some of the new
3217 hash table functions in lib/silccore/idcache.c
3219 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3221 * Added new function silc_hash_table_find_all to return all keys
3222 in the hash table by the specified key. As the hash table is
3223 collision resistant it also makes it possible to have several
3224 duplicate keys in the hash table. This function may be used to
3225 find all of the keys from the hash.
3227 Added user_context arguments to the SilcHashFunction,
3228 SilcHashCompare and SilcHashDestructor to deliver user specified
3231 Added new fuctions silc_hash_table_find[_all]_ext to do
3232 extended lookup with specified hash and compare functions and
3233 specified user contexts.
3235 Added new function silc_hash_table_add_ext to add the key
3236 with specified hash function and user context.
3238 Added new function silc_hash_table_foreach to traverse all
3239 entrys in the hash table. Added SilcHashForeach callback
3242 Added new function silc_hash_table_del_by_context to delete
3243 the entry only if the context associated with the key matches.
3245 Affected files are lib/silcutil/silchashtable.[ch].
3247 * Removed silc_hash_[server/client/channel]_id and added just
3248 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3249 silc_hash_id_compare to compare two ID's using as the hash table
3250 comparison function. Added also silc_hash_data to hash
3251 binary data and silc_hash_data_compare to compare it.
3253 * Removed silc_idlist_find_client_by_hash as it is not needed
3254 anymore. Affected file silcd/idlist.[ch].
3256 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3257 to use internally the SilcHashTable. The new ID Cache is a lot
3258 faster than the old one. Some of the ID Cache interface was also
3259 rewritten and obsolete and stupid functions were removed.
3261 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * Added entry_count field to the SilcHashTable to keep the number
3264 of the entries in the table. Implemented the function
3265 silc_hash_table_rehash. Added new function
3266 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3268 Fixed a minor bug in silc_hash_table_free.
3270 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3271 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3272 into the lib/silcutil/silcutil.[ch].
3274 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * Implemented a collision resistant hash table into the
3277 lib/silcutil/silchashtable[ch]. See the header and the source
3278 for the SilcHashTable API.
3280 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Merged dotconf version 1.0.2 into lib/dotconf.
3284 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Do not compile anything in lib/silcsim/* if the SIM support
3287 is not enabled. The tree should now compile without problems
3290 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Compiled the SILC under cygwin. Compiled and tested briefly
3293 without problems. More tests needed. The SIMs didn't compile
3296 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3298 * Fixed possible crash in silc_get_username in the
3299 lib/silcutil/silcutil.c.
3301 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Fixed a va_arg in silc/client_ops.c.
3305 * Oops, RC5 routines were named AES and caused some problems
3306 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3308 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Added new SilcIDIP structure into the lib/silccore/id.h and
3311 replaced the old `ip' fields from all SILC ID's to that type.
3312 This is a step towards IPv6 support.
3314 The silc_id_get_len takes now the ID as an extra argument.
3315 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3316 both IPv4 and IPv6 based ID's.
3318 The affected files are lib/silccore/id.[ch] and other files
3319 around the tree using these routines.
3321 * Removed the ID length arguments in server from various
3322 silc_server_send_notify_* routines -> they are not needed
3325 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Fixed memory leak in silc_encode_pem_file in the file
3328 lib/silcutil/silcutil.c.
3330 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Check minor version as well in the SKE. Affected files are
3333 silcd/protocol.c and lib/silcclient/protocol.c.
3335 * Added --identifier option to the server so that an identifier
3336 can be when creating the public key for the server. Affected
3337 file is silcd/silcd.c.
3339 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3340 lib/silccrypt/silcpkcs.c.
3342 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Register default ciphers and stuff when using -C option with
3345 the server. Affected file sildc/silcd.c.
3347 * Put back the servers public key filename format, it is better
3348 than the new one. For now, the client keys are saved with the
3349 new filename format. The affected file silc/client_ops.c.
3351 * Implemented the Cipher API for the rest of the ciphers that
3352 did not implement it or implemented it the wrong way.
3354 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3356 * Register default ciphers and stuff when using the -S option
3357 in the client. Affected file silc/silc.c. Same also when
3358 creating new key pair with -C option.
3360 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Fixed the silc_verify_public_key client operation function to
3363 save the public keys differently. The fingerprint is now
3364 used as filename and not the hostname. This way also the
3365 client keys are saved uniquely and not with hostnames. The
3366 affected file is silc/client_ops.c.
3368 * Trimmed the silc_hash_fingerprint function to remove extra
3369 whitespaces from the end of the fingerprint. The affected
3370 file is lib/silccrypt/silchash.c.
3374 * Added silc_cipher_register_default function to register all
3375 default ciphers. It can be used when configuration files
3376 does not exist and the application does not want any specific
3377 ciphers in any specific order.
3379 The SilcDList is now used as silc_cipher_list dynamically
3380 allocated cipher list. Removed the static list all together
3381 and now all ciphers must be allocated to the dynamic list.
3382 The silc_cipher_alloc routine was changed to check only the
3385 All silc_cipher_* routines that used to return int returns
3388 The affected files lib/silccrypt/silccrypt.[ch].
3390 * The same thing was done to silc_hash_* as for silc_cipher_*
3391 routines. Affected files lib/silccrypt/silchash.[ch].
3393 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3394 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3395 Added also silc_pkcs_[un]register[_default] functions.
3396 Removed the data_context from the PKCS API.
3398 * Added silc_hmac_register_default function to register default
3399 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3400 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3401 to unregister all hmacs at once.
3403 * Register the default ciphers, hash functions, PKCSs and HMACs
3404 if client's configuration file does not exist. The affected
3407 * The client did not load the hash functions from the SIM
3408 modules at all. Added support for this. Affected file is
3409 silc/clientconfig.c.
3411 * When decoding public key with silc_pkcs_public_key_decode, check
3412 the supported algorithm only if PKCS are registered. Affected
3413 file lib/silccrypt/silcpkcs.c. The same was done with the
3414 silc_pkcs_private_key_decode.
3416 * Fixed the SILC List routines to keep the list always in order.
3417 It used to change the list's order when traversing the list but
3418 not it preserves the order. Affected file lib/trq/silclist.h.
3420 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3422 * Added the client library to use the SilcSocketConnection's
3423 reference counter (by silc_socket_dup) to prevent the bug that
3424 the socket object may be freed underneath async operation.
3426 * The name resolv library checking fixes in the configure.in.pre.
3429 * Created new version of the protocol drafts for future
3430 development. The -03 drafts are the ones that will be changed
3431 in the trunk now and the -02 will remain as they are.
3433 * Send list of CUMODE notifys to the router when announcing
3434 the channel users to the router. Affected file silcd/server.c.
3435 If the router receiving channel founder CUMODE for a channel
3436 that already has channel founder it will send CUMODE notify
3437 to the sender to remove the channel founder rights from the
3438 announced client. Affected file silcd/packet_receive.c.
3440 * The CUMODE notify may now use Server ID as well as the entity
3441 who changes the mode. Updated protocool specs.
3443 * Updated INSTALL and README files.
3445 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * New web pages in the http://silc.pspt.fi. The pages was
3452 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Implemented the [DenyConnectin] config section in the server.
3455 Added silc_server_config_denied_conn to check whether incoming
3456 connection is denied. Affected file silcd/serverconfig.[ch].
3458 * Do not check the ports when checking the incoming configuration
3459 data if the port is 0, meaning any. Affected file is
3460 silcd/serverconfig.c.
3462 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Fixed buffer overflow in silc_string_compare in the file
3465 lib/silcutil/silcutil.c.
3467 * Fixed double free in silc_server_command_leave in the file
3470 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * Fixed the version checking in the server. Affected file is
3475 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Fixed the configuration data fetching when accepting new
3478 connections in the server. Affected file silcd/server.c.
3480 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Added `sender_entry' argument to the function
3483 silc_server_packet_relay_to_channel so that we can check
3484 whether some destination actually belongs to the same route
3485 the sender belongs (ie, we must not resend the packet to the
3486 sender). Affected file silcd/packet_send.[ch].
3488 * Added `servername' field to the SilcClientEntry in the server
3489 to hold the name of the server where client is from. Affected
3490 file is silcd/idlist.h.
3492 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3494 * Moved the channel message encrypting in the router betwen
3495 router connections from silc_server_channel_message to the
3496 silc_server_packet_relay_to_channel since we want to check
3497 whether we have anybody channel before encrypting anything.
3498 Affected files silcd/packet_[receive/send].c.
3500 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Fixed the [AdminConnection] server config section to support
3503 multiple entries. Affected file silcd/serverconfig.c.
3505 * Added support into the server to check the validity of the
3506 incoming connection before executing any KE or authentication
3509 * The connection configuration is now saved to the KE and
3510 connection auth protocol contexts and not fetched anymore in
3511 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3513 * The local hosts listenning address and port is also resolved
3514 now when starting the server. We want to have the socket object
3515 to include the real address and port for the listener. Added
3516 new function silc_net_check_local_by_sock into the files
3517 lib/silcutil/silcnet.[ch].
3519 * Fixed a broadcast bug in server -> do not broadcast if we
3522 * Fixed a routing bug. Do not route broadcast packets ever.
3523 Broadcast packets must be processed always and not routed since
3524 they may be destined to some other host than yourself and thus
3525 would get routed without no good reason. Affected file is
3528 * Added function silc_server_config_is_primary_route to check
3529 whether primary router connection has been configured (a router
3530 configuration that we are initiating). If there is not, we
3531 will assume that there is only two routers in the SILC network
3532 and we will use the incoming router connection as our primary
3533 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3535 * Changed the order of the broadcasting. Broadcast _after_ the
3536 packet has been processed not before. Affected file is
3539 * Fixed a [ClientConnection] parsing bug. The port was never
3540 parsed correctly thus resulting to port 0. Affected file
3541 silcd/serverconfig.c.
3543 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3544 argument and did not set the broadcast packet flag. Affected
3545 file silcd/packet_send.c. Fixed same bug in the function
3546 silc_server_send_notify as well.
3548 * If we receive NEW_ID packet for our own ID in the server, ignore
3551 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3555 * Removed the nickname from the Private Message Payload.
3556 Updated the code and the protocol specs.
3558 * Updated protocol specs for submitting to the IETF.
3560 * Tweaked the Random Number Generator a bit. Affected file
3561 lib/silccrypt/silcrng.c. Exported a new function
3562 silc_rng_[global]_add_noise which can be used to add more
3565 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3567 * Do not parse packets with different timeout when protocol
3568 is active -> may cause problem with rekey. Affected file
3571 * When server receives signoff notify it must not create
3572 new channel key if the client is on any channels since the
3573 sender of the signoff notify will create it.
3575 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Added printing of error messages during SKE protocol from the
3578 failure packet sent by server during SKE. Affected file
3581 * Removed the client's failure_callback handling with timeout
3582 and handle it immediately when received.
3584 * The SKE library returned wrong type in SUCCESS and FAILURE
3585 packets. They must be 32 bit MSB not 16 bit MSB.
3587 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3589 * Ok, rewrote the logic of the re-key and now it seems to work.
3590 I tested it on high traffic with frequent re-keys without
3591 problems. Added hmac_receive (and renamed hmac to hmac_send)
3592 in SilcClientConnection in lib/silcclient/client.h and
3593 in SilcIDListData in silcd/idlist.h. Also, removed the
3594 SilcPacketParserContext's cipher and hmac fields as they are
3595 not needed anymore and actually caused some problems when
3596 the ciphers and hmac's changed underneath the packet parser.
3598 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * If re-key protocol is active then process the incoming packets
3601 synchronously since we must assure that icoming packets encrypted
3602 with the old key is processed before the new keys is set to
3603 use. This is true other packets than for REKEY packets.
3604 Affected file silcd/server.c. The same was done to client library
3605 as well, affected file lib/silcclient/client.c.
3607 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3609 * Fixed bug in client and server to accept the force send if
3610 the packet is send from silc_[server/client]_packet_process
3611 function. Otherwise the packets are never delivered, oops.
3613 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Disable force sending of packets when REKEY protocol is active.
3616 We must assure that no packet is sent directly when rekey is
3617 performed. All packets must be sent through packet queue.
3618 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3619 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3620 function is silc_[server/client]_packet_send_real to check
3623 * Replaced the SIM paths from example config files to
3624 /usr/local/modules. Also, make install creates now
3625 /usr/local/silc/logs directory to hold all the SILC server
3628 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Made the configure.in.pre work on Solaris. Patch by salo.
3632 * Made all ciphers compatible with non-x86 machines. Defined
3633 CBC mode macros into lib/silccrypt/ciphers_def.h.
3635 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * Fixed the make install.
3639 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * When MAC computation fails the silc_packet_decrypt returned 0
3642 even though it was supposed to return -1. Fixed this. The
3643 affected file is lib/silccore/silcpacket.c.
3645 * Do not replace the config files in /etc/silc (in make install)
3646 if they already exist. Affected file ./Makefile.am.
3648 * Do not send re-key packets immediately but through packet queue.
3649 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3651 * Changed silc_net_check_host_by_sock to return FALSE if the
3652 IP/DNS could not be resolved. Though, it returns the IP address
3653 now even if it could not resolve it (but returns also FALSE).
3654 Affected file lib/silcutil/silcnet.[ch].
3656 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Added silc_pkcs_decode_identifier to decode the public key's
3659 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3660 Added also silc_pkcs_free_identifier. Added also new context
3661 SilcPublicKeyIdentifier.
3663 * Added -S option to the silc client. It is used to dump the
3664 contents of the specified public key file.
3666 * Changed the PKCS api to return the public key length when
3667 setting the public key.
3669 * Fixed a fatal bug in the public and private key file loading.
3670 Affected file lib/silccrypt/silcpkcs.c.
3672 * Execute the packet parsing for client with zero (0) timeout
3673 if the protocol is active. Affected file silcd/server.c.
3675 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Made the key generation options to the silcd program. Added
3678 -C option, equivalent to client's option.
3680 * Added new [ServerKeys] config section to the server. It
3681 configures the server's public and private key.
3683 * Defined generic Public Key Payload into the protocol
3684 specification to send specific type of public keys and
3687 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3688 public key or certificate.
3690 * Implemented the GETKEY command to the server and to the
3691 client library and on user interface.
3693 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Made preliminary `make install' work.
3697 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * Added SilcServerRekey context into silcd/idlist.h.
3701 * Added the PFS support as defined in the specification to the
3702 SKE protocol. Affected files lib/silcske/*.c.
3704 * Added `ske_group' field to the SilcServerRekey context to hold
3705 the number of the SKE group that is used with PFS in re-key.
3706 Affected file silcd/idlist.h.
3708 * Added PFS re-key support to the server. Affected file is
3711 * Added silc_protocol_cancel to cancel execution of the next
3712 state of the protocol. Affected file is
3713 lib/silccore/silcprotocol.[ch].
3715 * Added the re-key support with and without PFS to the client
3716 library. Re-key is performed once in an hour, by default.
3718 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3719 Added silc_client_rekey_callback and silc_client_rekey_final.
3720 Affected files are lib/silcclient/protocol.[ch] and
3721 lib/silcclient/client.[ch].
3723 * Removed the `hmac_key' and `hmac_key_len' fields from the
3724 SilcClientConnection structure; not needed. Affected file is
3725 lib/silcclient/client.h.
3729 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Do not ask whether user wants to use the negotiated private key
3732 for private messages, just use it. Affected file is
3733 silc/local_command.c.
3735 * Added `send_enc_key' and `enc_key_len' fields to the
3736 SilcIDListData structure since they are needed in the re-key
3737 phase. Affected file is silcd/idlist.[ch].
3739 * Implemented the simple re-key protocol into the server.
3740 Affected files silcd/server.c and silcd/protocol.[ch]. The
3741 re-key will be performed once in an hour, by default.
3743 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3744 Added silc_server_rekey, silc_server_rekey_callback and
3745 silc_server_rekey_final.
3747 * Removed Tunneled flag from the protocol. Updated the code
3748 and the specifications.
3750 * Adde `pfs' field to the SilcIDListData to indicate whether
3751 the PFS is to be performed in the re-key. Affected file is
3754 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3757 int64 of at least the xintXX size. If void * is less that 4
3758 bytes uint32 * will be used. Defined bool as boolean.
3760 * Changed _ALL_ unsigned long and unsigned int to uint32,
3761 unsgined short to uint16 in the source tree.
3763 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3764 not handle clients that has entry->data.registered == FALSE.
3765 They are not in the network anymore. Affected file is
3768 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Implemented the sending of the SERVER_SIGNOFF notify in the
3771 server. Affected file is silcd/server.c.
3773 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3774 Added also silc_notify_payload_encode_args into the
3775 lib/silccore/silcnotify.[ch].
3777 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3778 Affected file silcd/packet_receive.c.
3780 * Implemented the SERVER_SIGNOFF notify handling in the client
3781 library. Affected file lib/silcclient/client_notify.c. Also,
3782 implemnted the printing of the SERVER_SIGNOFF info to the
3783 application. Affected file silc/client_ops.c.
3785 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3786 if the deleting was successful. Affected file silcd/idlist.[ch].
3788 * Added support for public key authentication in the connection
3789 authentication protocol in the client library. Affected file
3790 lib/silcclient/protocol.c.
3792 * Changed the server's silc_idlist_get_clients_by_* interface
3793 to support already allocated array so that new entries may be
3794 added to pre-allocated array. Affected file silcd/idlist.[ch].
3795 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3796 and command replies.
3798 * All command reply functions in the server now calls the
3799 pending command callback even if error occured. This way the
3800 error will be delivered to the client as well. Affected files
3801 silcd/command.c and silcd/command_reply.c.
3803 * Fixed INFO command to return local server's info if no server
3804 was provided. Affected file lib/silcclient/command.c.
3806 * Removed RESTART command for good. Updated the code and the
3809 * Rewrote parts of the task system. It is a bit simpler now.
3810 Removed unsued task priorities. The affected files are
3811 lib/silcutil/silctask.[ch].
3813 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Moved the USERS printing from the library to the application.
3816 Affected files lib/silcclient/command.c and silc/client_ops.c.
3818 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Added channel key re-key support. The re-key is perfomed
3823 only by the router and is done once in an hour. Added `rekey'
3824 field to the SilcChannelEntry in the server. Affected files
3825 silcd/server.c and silcd/idlist.h.
3827 * Added silc_task_unregister_by_context into the file
3828 lib/silcutil/silctask.[ch].
3830 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Added SILC_UMODE_GONE mode to indicate when the client is not
3833 present in the SILC network. Added also support to the local
3834 command AWAY that will set this mode. Added support of showing
3835 "xxx is gone" in WHOIS command. The USERS command shows the
3836 gone status as well.
3838 * Fixed setting server and router operator privileges in the
3839 server's UMODE command. Affected file silcd/command.c.
3841 * Merged the SKE KE1 and KE2 payloads into one payload. The
3842 new KE payload is equivalent to the old KE2 payload.
3844 Cleaned up the SKE Start Payload parsing. It now uses the
3845 simple buffer unformatting to do the parsing. A lot faster
3848 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3849 to the SKE that is used to indicate whether both of the SKE
3850 parties should perform authentication. By default only the
3851 responder performs authentication. By setting this flag also
3852 the initiator must do authentication. By default it is unset
3853 since in normal SKE case, client to server connection, only
3854 the responder should do authentication. When doing SKE between
3855 two clients both should perform authentication. Updated the
3856 code and the protocol specs.
3858 * A little fix to IDENTIFY command in the server. Search the
3859 client first by hash not nickname. Affected file is
3862 * Fixed the silc_client_close_connection to support closing
3863 the client to client connections wihtout deleting too much
3864 data. Affected file lib/silcclient/client.c.
3866 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3867 are received if protocol used to be active but is not anymore
3868 the application would crash due to NULL pointer dereference.
3869 Affected files silcd/server.c and lib/silcclient/client.c.
3871 * Added `hash' field to the SilcClientConnection to include
3872 the hash function negotiated in the SKE protocol.
3874 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3875 to set the channel founder authentication data. A client can
3876 claim the founder rights later by providing the authentication
3877 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3878 This way the channel founder can regain the channel founder
3879 privileges even it is left the channel. This works only on
3880 local server and the client must be connected to the same
3881 server to be able to regain the founder rights. Updated the
3882 protocol specs accordingly.
3884 Added support to the CMODE command in the client to set the
3885 founder auth data. Read the README to see how to set it.
3887 Added support to the CUMODE command to claim the founder
3888 rights. Read the README to see how to do it.
3890 Added support for the founder authentication to the Channel
3891 Entry in the server. Affected file silcd/idlist.h.
3893 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3894 server's CMODE command. Affected file silcd/command.c.
3896 * Added the following new functions into lib/silccore/silcauth.[ch]:
3897 silc_auth_get_method and silc_auth_get_data.
3899 * The server now saves the remote hosts public key to the
3900 SilcIDListData pointer. Affected file silcd/protocol.c.
3902 * The normal server now does not remove the channel entry from
3903 the cache if the founder authentication data is set. It used
3904 to remove it if the founder was the last one on the channel on
3905 the server and left the channel. The auth data is saved and
3906 if the channel is re-joined later the old entry is used with
3907 the old auth data. Affected files silcd/command_reply.c and
3910 * Removed the `pkcs' field from the SilcIDListData structure
3911 in the server; it is not used. Affected file silcd/idlist.h.
3913 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3915 * Fixed packet processing on slow links. Partial packets were
3916 never re-processed because the incoming data buffer was cleared
3917 by the application. Application must not directly clear the
3918 sock->inbuf, the packet processing routines handle it. Fixed
3919 this in client library and in server.
3921 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3923 * Fixed the WHOIS and IDENTIFY send reply function to really
3924 check whether to send list or just one entry. Affected file
3927 * Cleaned up the LEAVE command's channel key distribution. The
3928 affected file silcd/command.c.
3930 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3931 can enforce the channel mode as well. In that case the ID
3932 includes the ID of the server. The code now enforces the
3933 mode change if the router have different mode than the server.
3935 * The notify client operation with CMODE_CHANGE notify can now
3936 return NULL client_entry pointer if the CMODE was not changed
3937 by client. Application must check for this.
3939 * Added <Server ID> argument to INFO command to support server
3940 info fetching by Server ID.
3942 * Added silc_server_announce_get_channel_users to get assembled
3943 packets of channel users of the specified channel. Affected
3944 file silcd/server.[ch].
3946 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3947 was freed underneath the ID Cache.
3949 * Re-announce clients when the server received CHANNEL_CHANGE
3950 notify from the router. Affected file silcd/packet_send.c.
3952 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3955 crashed since it did not handle the fact that there is no cipher
3956 called "3" and didn't check the error condition. Now fixed.
3958 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3959 flag. It can be used to send message requests.
3961 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * Implemented the RESTART command in the client.
3965 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3966 notice type messages. Added notice printing to the user
3969 * The channel keys are not re-generated if the channel's mode
3970 is PRIVKEY, ie private key on the channel exists. Affected
3971 files silcd/server.c and silcd/command.c.
3973 * Fixed a little bug in channel message delivery when channel
3974 private keys are set in the server. Affected file is
3975 silcd/packet_send.c.
3977 * Changed the setting on channel->on_channel = TRUE from the
3978 silc_client_save_channel_key to the JOIN command reply. The
3979 key payload is not received if the private channel key is set.
3980 Affected file lib/silcclient/command_reply.c and the
3981 lib/silcclient/client_channel.c.
3983 * When the CMODE_CHANGE notify is sent and the channel private
3984 key mode is removed the channel key must be re-generated in
3985 other cells as well. Added this support for the router in the
3986 silcd/packet_receive.c.
3988 * Added new local command NOTICE to send notice message on
3989 channel. Affected file silc/local_command.[ch].
3991 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Added new local command ME to the client. It is used to send
3994 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3995 some action. Affected file silc/local_command.[ch].
3997 * Changed channel_message and private_message client operations
3998 to deliver the message flags to the application. Added also
3999 the `flags' arguments to the silc_client_send_channel_message
4000 and silc_client_send_private_message functions. Affected file
4003 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Redefined the Private Message Payload to support private message
4006 keys and to support the new private message flags. Updated
4007 the protocol specs. Flags makes it possible to have for example
4008 CTCP style messages.
4010 * Added new type SilcPrivateMessagePayload and defined an API
4011 for it in the lib/silcclient/silcprivate.[ch].
4013 * Tested private message private keys successfully. Tested the
4014 private message key set, unset and list commands with the new
4017 * Redefined the Channel Message Payload to include the channel
4018 message flags (equal with private message flags) to support
4019 for example CTCP style messages.
4021 * Defined some of the message (for channel and private message)
4022 flags. Updated the protocol specs and added the flags to the
4023 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4025 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Added SilcKeyAgreementStatus type to the key agreement routines
4028 to indicate the current status and error if one occured.
4029 The status types are defined in the lib/silcclient/silcapi.h.
4031 * Added new local command KEY that is used to set and unset private
4032 keys for channels, set and unset private keys for private messages
4033 with remote clients and to send key agreement requests and
4034 negotiate the key agreement protocol with remote client. The
4035 key agreement is supported only to negotiate private message keys,
4036 it currently cannot be used to negotiate private keys for channels,
4037 as it is not convenient for that purpose.
4039 * Fixed a minor pending callback setting bug in the function
4040 silc_client_get_client_by_id_resolve, now the function works.
4041 Affected file lib/silcclient/idlist.c.
4043 * Added function silc_net_get_local_port to get local bound
4044 port by socket. Added to lib/silcutil/silcnet.[ch].
4046 * Added `sockets' and `sockets_count' fields to the SilcClient
4047 object. They hold the sockets of the listenning sockets in
4048 the client. Listenning sockets may be for example the key
4049 agreement server. Affected file lib/silcclient/client.[ch].
4050 Added functions the silc_client_add_socket and the
4051 silc_client_del_socket. They are exported to the application
4054 * Added ~./silc/clientkeys to support other client's public keys.
4056 * Renamed verify_server_key client operation to verify_public_key
4057 and added one argument to indicate the type of the connection
4058 (server, client etc.).
4060 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Added silc_server_connection_auth_request to handle the
4063 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4064 silcd/packet_receive.[ch].
4066 * Added silc_server_send_connection_auth_request into the
4067 silcd/packet_send.c to send the connection auth request packet.
4069 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4072 * Fixed the public key authentication in responder side in the
4073 server. The `auth_data' pointer includes the SilcPublicKey
4074 not the path to the public key. Affected file silcd/protocol.c.
4076 * Implemented the public key authentication in the initiator side
4077 in the server. Affected file silcd/protocol.c.
4079 * Removed the [RedirectClient] config section from the server
4080 configuration. Is not needed and I don't want to implement it.
4082 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Cleaned up the CMODE command in the server. It now works
4085 correctly and supports all the modes defined in the protocol.
4086 Affected file is silcd/command.c.
4088 * Added `hmac_name' field to the SilcChannelEntry in the server
4089 to hold the default HMAC of the channel. It can be set when
4090 creating the channel (with JOIN command). Affected files
4093 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4094 type to indicate the change of the current cipher and hmac
4095 on the channel. Client can safely ignore the <cipher> argument
4096 (if it chooses to do so) since the CHANNEL_KEY packet will
4097 force the channel key change anyway. The <hmac> argument is
4098 important since the client is responsible of setting the new
4099 HMAC and the hmac key into use.
4101 * Fixed the CMODE command in the client library as well.
4103 * Tested CMODE command in router environment successfully.
4105 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4107 * Show the version of the remote client (or server) when connecting
4108 to the server. It is logged to the log file. Affected file
4109 is silcd/protocol.c.
4111 * Fixed the KILLED notify handling in the client library. The
4112 client must be removed from all channels when receiving the
4115 Also, do not remove the client entry when giving the KILL
4116 command but when the KILLED notify is received.
4118 * Removed silc_idlist_find_client_by_nickname from the server.
4119 Not needed anymore. Affected files silcd/idlist.[ch].
4121 * Implemented the CHANNEL_CHANGE notify type handling to the
4122 server. Affected file silcd/server.c.
4126 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Added silc_server_send_notify_invite to send the INVITE
4129 notify between routers.
4131 * Implemented the INVITE command correctly to the server.
4133 * Implemented the INVITE notify type handling in the server.
4135 * Implemented the INVITE command to the client library and on the
4138 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Added function silc_server_get_client_resolve to find the
4141 client entry by ID from all ID lists and then resolve it
4142 (using WHOIS) if it cannot be found. Affected file is
4145 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Implemented the BAN command to the client library.
4149 * The JOIN command in the server now checks the invite list
4152 * Changed the silc_command_reply_payload_encode_va and the
4153 silc_command_payload_encode_va to support that if argument is
4154 NULL it ignores and checks the next argument. Affected file
4155 lib/silccore/silccommand.c.
4157 * Added silc_server_send_notify_ban to send the BAN notify
4158 type between routers.
4160 * Chaned the silc_notify_payload_encode to support that if
4161 argument is NULL it ignores and checks the next argument.
4162 Affected file lib/silccore/silcnotify.c.
4164 * Tested ban lists in router environment successfully.
4166 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Implemented BAN command to the server, in silcd/command.[ch].
4170 * Removed the BAN and INVITE_LIST modes from the CMODE command
4173 * Added function silc_string_match to regex match two strings.
4174 Affected files lib/silcutil/silcutil.[ch].
4176 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Redefined parts of the SilcChannelEntry in the server to support
4179 the new ban and invite lists.
4181 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Redefined the INVITE command. The same command can be used to
4184 invite individuals to the channel but also to manage the invite
4185 list of the channel (to add to and remove from the invite list).
4186 Updated the protocol specs.
4188 * Added new command SILC_COMMAND_BAN that can be used to manage
4189 the ban list of the channel. Updated the protocol specs.
4191 * Removed the channel modes: the SILC_CMODE_BAN and the
4192 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4193 in the CMODE command. The equivalent features are now available
4194 using INVITE and BAN commands. Updated the protocol specs.
4196 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4197 in the network about change in the current ban list. The notify
4198 type is not used by the client.
4200 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4201 support the invite lists.
4203 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Added new function silc_string_regexify that converts string
4206 including wildcard characters into regex string that can
4207 be used by the GNU regex library. Added into the file
4208 lib/silcutil/silcutil.[ch].
4210 Added silc_string_regex_combine to combine to regex strings
4211 into one so that they can be used as one regex string by
4212 the GNU regex library. Added into the file
4213 lib/silcutil/silcutil.[ch].
4215 Added silc_string_regex_match to match two strings. It returns
4216 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4218 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Imported GNU regex to the soruce tree into lib/contrib.
4221 Fixed some compiler warning from the regex.c.
4223 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Fixed MOTD command in the server to work in router environment.
4227 * Fixed the MOTD command in the client library to support
4228 the server argument in the command.
4230 * Added `nickname_len' argument to the silc_idlist_add_client
4231 in the server, as the `nickname' argument may be binary data
4234 * Added silc_idlist_get_channels to return all channels from
4237 * Implemented LIST command to the server. Affected file is
4240 * Implemented the LIST command to the client library and on the
4243 * Added [<user count>] argument to the LIST command reply.
4244 With private channels the user count is not shown.
4246 * Updated TODO and README.
4248 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * The client entry's data.registered must be TRUE even with
4251 global client entry on global client list. The data.registered
4252 is used to check whether the client is anymore in the network,
4253 for example with WHOWAS command so it must be valid.
4255 * Fixed the WHOWAS command in the server. It now actually works
4256 in router environment. Added function into silcd/command_reply.c
4257 silc_server_command_reply_whowas_save.
4259 * Added silc_idlist_purge function to the silcd/idlist.c
4260 to periodically purge the ID Cache.
4262 * Fixed INFO command in the server. It works now in router
4263 environment. Added <server name> argument to the INFO command
4264 reply. Updated the protocol specs.
4266 * Fixed minor bug in silc_idcache_purge to not purge if the
4267 expire value is zero.
4269 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4270 they were buggy because of the WHOWAS information.
4272 * Fixed local command MSG to handle the async resolving of
4273 the remote client properly. It used to fail the first MSG.
4274 Affected file silc/local_command.c.
4276 * Added `data_len' field to SilcIDCache context.
4278 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4280 * Update TODO. Todo in commands in the server.
4282 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4285 used by routers as broadcast packet to inform other routers
4286 about the changed user mode.
4288 Implemented the notify handling in the server. Affected file is
4289 silcd/packet_receive.c. Added the function
4290 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4292 * Added new generic Channel Payload and deprecated the New Channel
4293 Payload. The New Channel Payload is now the generic Channel
4296 * Added new argument `mode' to the silc_server_send_new_channel
4297 as it is required in the Channel Payload now.
4299 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4300 and created a new and real SilChannelPayload to represent the
4301 new generic Channel Payload. Implemented the encode/decode
4302 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4304 * Added silc_server_get_client_channel_list to return the list
4305 of channels the client has joined for WHOIS command reply.
4306 Affected file silcd/server.[ch].
4308 * Implemented the channel list sending in the WHOIS command reply
4309 in server and in the client.
4311 Implemented the channel list displaying on the user interface
4312 as well. Affected file silc/client_ops.c.
4314 * Added silc_channel_payload_parse_list to parse list of Channel
4315 Payloads. It returns SilcDList list of SilcChannelPayloads.
4316 Client for example can use this function to parse the list of
4317 channels it receives in the WHOIS command reply. The caller
4318 must free the list by calling silc_channel_payload_list_free.
4319 Affected files lib/silccore/silcchannel.[ch].
4321 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4323 * Added one new argument <user mode> to the WHOIS command reply
4324 to return the mode of the user in SILC. Updated the protocol
4327 Implemented it to the server and client.
4329 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Fixed the mode printing on the user interface on joining.
4332 Affected file silc/client_ops.c.
4334 * Implemented the UMODE command and user modes in general to the
4335 client library and to the user interface.
4337 * Implemented the UMODE command to the server.
4339 * The server now sends UNKNOWN_COMMAND error status if client sends
4340 unknown command. Affected file silcd/command.c.
4342 * All server commands now handle the command identifier the right
4343 way when sending the command reply to the client. The client can
4344 use to identify the command replies with the identifier.
4346 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Added silc_server_get_client_route to resolve the route to
4349 the client indicated by the client ID. Affected file is
4352 * Added silc_server_relay_packet as general function to relay
4353 packet to arbitrary destination. This deprecates functions
4354 like _send_private_message_key, _relay_notify etc. Affected
4355 file is silcd/packet_send.[ch].
4357 Removed silc_server_send_key_agreement,
4358 silc_server_send_private_message_key and
4359 silc_server_packet_relay_notify functions from the file
4360 silcd/packet_send.[ch].
4364 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4365 server. Affected file silcd/packet_receive.[ch].
4367 * Implemented the KILL command to the client. Implemented the
4368 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4369 Affected files lib/silcclient/command[_reply].c and
4370 lib/silcclient/client_notify.c. Implemented the KILL notify
4371 printing in the user inteface.
4373 * Fixed a lot silc_parse_nick memory leaks from the client
4374 library in the file lib/silcclient/command.c.
4376 * Changed the silc_server_send_notify_on_channels's `sender'
4377 argument from SilcSocketConnection to SilcClientEntry to
4378 check the sender as entry and not as connection object and not
4379 to send to the client provided as argument. The affected file
4380 is silcd/packet_send.[ch].
4382 * The notify packets that are destined directly to the client used
4383 to not to be processed by the server. Now changed that and the
4384 server processes all notify packets. After relaying the packet
4385 to the client the notify packet is processed in the server.
4387 * The silc_server_free_client_data now checks whether there is
4388 pending outgoing traffic for the client and purges the data to
4389 the network before removing the client entry.
4391 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4394 an client is killed from the SILC Network. Updated the protocol
4397 Added new function silc_server_send_notify_killed to the
4398 silcd/packet_send.[ch].
4400 * Added function silc_server_packet_relay_notify to relay notify
4401 packets that are destined directly to a client. In this case
4402 the server does not process the notify packets but merely relays
4403 it to the client. Affected file silcd/packet_send.[ch].
4405 Added also silc_server_packet_process_relay_notify to check
4406 whereto relay the notify. Affected file is
4407 silcd/packet_receive.[ch].
4409 * Implemented the KILL command to the server.
4413 * Added the backup schema desgined last fall to the protocol
4414 specs for everyone to see. The specification is in the
4415 *-spec-xx.txt draft and the packet type definitions for the
4416 backup routers is in *-pp-xx.txt draft. Thusly, added also
4417 new packet type SILC_PACKET_CELL_ROUTERS.
4419 * A big security problem in the implementation discovered. The
4420 signoff of an client did not cause new channel key generation
4421 which it of course should've done. The channel keys must be
4422 always re-generated when client leaves (or signoffs) the channel.
4423 The silc_server_remove_from_channels funtion now handles
4424 the channel key re-generation.
4426 * Added `sender' argument to the silc_server_send_notify_on_channels
4427 to not to send the client provided as argument. Affected file
4428 silcd/packet_send.[ch].
4430 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Implemented OPER and SILCOPER commands into the server and
4435 * Added silc_auth_verify and silc_auth_verify_data to verify
4436 the authentication directly from the authentication payload.
4437 It supports verifying both passphrase and public key based
4438 authentication. Affected file lib/silccore/silcauth.[ch].
4440 * Added `hash' field to the SilcIDListData structure. It is the
4441 hash negotiated in the SKE protocol. Affected file is
4444 * Slight redesigning of the SilcAuthPayload handling routines.
4445 Do not send SilcPKCS but SilcPublicKey as argument.
4447 * Implemented the public key authentication support to the
4448 serverconfig. The public key is loaded from the provided path
4449 and saved as authentication data to void * pointer. Thus,
4450 changed the unsigned char *auth_data to void *auth_data;
4452 * Fixed SHUTDOWN command to send the reply before the server
4453 is shutdown. :) Affected file silcd/command.c.
4455 * Fixed fatal bug in CONNECT command. The hostname was invalid
4456 memory and server crashed. Affected file silcd/command.c.
4458 * Fixed fatal bug in CLOSE command. The server_entry became
4459 invalid but was referenced later in the command. Affected file
4462 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Fixed fatal bug in failure packet handling. Server ignored
4465 the failure and thus crashed when it came.
4469 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4472 that the command may be executed only once in (about) 2 seconds.
4473 The old SILC_CF_LAG flag is same but allows command bursts up
4474 to five before limiting.
4476 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4477 server code. Various commands now includes the CF_LAG_STRICT
4478 flag to disallow any kind of miss-use of the command.
4480 * Fixed the silc_buffer_unformat to not to allocate any data
4481 if the length of the data is zero. It used to allocate the
4482 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4484 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Changed the format of AdminConnection configuration section
4487 in the server. Added username of the admin to the format.
4488 Affected files silcd/serverconfig.[ch].
4490 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4491 to return admin configuration data by host, username and/or
4494 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4496 * Implemented WHOWAS command to the server. Added the functions:
4498 silc_server_command_whowas_parse,
4499 silc_server_command_whowas_send_reply,
4500 silc_server_command_whowas_from_client and
4501 silc_server_command_whowas_from_server
4503 * Added <Client ID> argument to the WHOWAS command reply. Updated
4504 the protocol specs accordingly.
4506 * Implemented WHOWAS command and command_reply to the client
4509 Implemented the WHOWAS printing on the user interface.
4511 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Added new argument to the WHOWAS command reply, the real name.
4514 It is an optional argument. Updated the protocol specs.
4516 * Added SilcIDCacheDestructor callback that is registered when
4517 the SilcIDCache is allocated. The callback is called when
4518 an cache entry in the ID Cache expires, or is purged from the
4519 cache. Added into lib/silccore/idcache.[ch].
4521 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4522 to destruct the client entries when the cache entry expires.
4523 Other ID Cache's in server and in the client library ignores
4526 * If the ID Cache entry's `expire' field is zero then the entry
4527 never expires. Added boolean `expire' argument to the
4528 silc_idcache_add function in the lib/silccore/idcache.[ch].
4529 If it is TRUE the default expiry value is used.
4531 * Added silc_server_free_client_data_timeout that is registered
4532 when client disconnects. By default for 5 minutes we preserve
4533 the client entry for history - for WHOWAS command.
4535 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Added support to the server to enforce that commands are not
4538 executed more than once in 2 seconds. If server receives
4539 commands from client more frequently, timeout is registered
4540 to process the commands. Affected file silcd/command.c.
4541 Added new function silc_server_command_process_timeout.
4543 * Changed NICK_NOTIFY handling in client library to check that
4544 if the client's nickname was changed, so there is no need to
4545 resolve anything from the server.
4547 * Removed error printing from the WHOIS and IDENTIFY commands.
4548 If error occurs then it is ignored silently in the client library.
4549 The application, however, may map the received error to
4550 human readable error string. The application currently maps
4551 the NO_SUCH_NICKNAME error to string.
4553 * Made the command status message public to the application. Moved
4554 them from lib/silcclient/command_reply.c to
4555 lib/silcclient/command_reply.h. The application can map the
4556 received command status to the string with the
4557 silc_client_command_status_message function.
4559 * Added check to the server to check that client's ID is same
4560 as the Source ID in the packet the client sent. They must
4563 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4565 * Added dist-bzip hook to the Makefile.am to make bzip2
4566 compressed distributions.
4568 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Server now enforces the maximum length for the nickname and
4571 the channel as protocol specification dictates. 128 bytes for
4572 nickname and 256 bytes for channel name.
4574 * Moved the WHOIS printing to the application. The client libary
4575 does not print out the WHOIS information anymore, the application
4576 must do it. Renamed silc_client_command_reply_whois_print to
4577 the silc_client_command_reply_whois_save.
4579 The client's idle time is also sent to the application now, and
4580 the idle is shown on screen.
4582 * Added silc_client_command_reply_identify_save to save the
4583 received IDENTIFY entries.
4585 * Do not check for channel private keys in message sending and
4586 reception if the channel does not have the PRIVKEY mode set.
4587 Affected file lib/silclient/client_channel.c.
4589 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4592 just surfaced after chaning the JOIN procedure.
4594 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Added silc_client_get_clients_by_list to get client entries
4597 from Client ID list, that is returned for example by JOIN
4598 and USERS command replies. The application should use this
4599 function for example when JOIN command reply is received to
4600 resolve the clients already on the channel (library does not
4601 do that anymore as USERS command reply is not used in the JOIN
4602 procedure anymore). Affected files lib/silcclient/silcapi.h and
4603 lib/silcclient/idlist.c.
4605 * JOIN command reply and USERS command reply returns now SilcBuffer
4606 pointers instead of unsigned char pointers when returning
4607 the client list and mode list.
4609 * Added <Client ID> argument to the JOIN command reply, mainly
4610 for the server to identify for which client the command was
4611 originally sent. Updated protocol specs accordingly.
4613 * Added SilcDlist private_key pointer to the SilcChannelEntry
4614 in the client to support the channel private keys. Affected
4615 file is lib/silcclient/idlist.h.
4617 * Added SilcChannelPrivateKey argument to the function
4618 silc_client_send_channel_message so that application can choose
4619 to use specific private ke if it wants to. If it is not provided,
4620 the normal channel key is used, unless private keys are set.
4621 In this case the first (key that was added first) is used
4622 as the encryption key.
4624 * Implemented the support for channel private key handling.
4625 Implemented the following functions:
4627 silc_client_add_channel_private_key,
4628 silc_client_del_channel_private_keys,
4629 silc_client_del_channel_private_key,
4630 silc_client_list_channel_private_keys and
4631 silc_client_free_channel_private_keys
4633 Affected file lib/silcclient/client_channel.c.
4635 * Added the support for the private keys in the channel message
4636 sending and encryption and in the message reception and
4637 decryption. Affected funtions are
4638 silc_client_send_channel_message and silc_client_channel_message.
4640 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Added SKE's key verify callback to the client library's
4643 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4645 * Removed the statement that server (or router) must send USERS
4646 command reply when joining to the channel so that the client
4647 knows who are on the channel. Instead, the client list and
4648 client's mode list is now sent in the JOIN command reply to the
4649 client who joined channel. This is better solution.
4651 * Added function silc_server_get_users_on_channel and function
4652 silc_server_save_users_on_channel to the silcd/server.[ch].
4654 * Removed function silc_server_command_send_users from the
4657 * Do not show topic on the client library anymore. The topic is
4658 sent in the command reply notify to the application and the
4659 application must show the topic now.
4661 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Added client searching by nickname hash into the IDENTIFY and
4664 WHOIS commands in the server as they were clearly missing from
4665 them. Affected file is silcd/command.c.
4667 * Fixed a bug in private message receiving in the client library.
4668 The remote ID was freed and it wasn't supposed, now it is
4671 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Minor fix to the channel payload; allocate the data area, as it
4674 needs to be of specific length.
4676 * If the key agreement port is zero then the operating
4677 system will define the bound port. Affected files are
4678 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4680 * Added new function silc_channel_payload_decrypt into the file
4681 lib/silccore/silcchannel.[ch].
4683 * Moved the channel message etc, check from silc_packet_decrypt
4684 to applications. The library calls now a generic
4685 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4686 when the packet is either normal or special. This was done to
4687 allow more wide range of checking that was not allowed when
4688 the code was in library. Now applications can do virtually any
4689 checks to the packet and return to the library the decision how
4690 the packet should be processed. Affected files are
4691 lib/silccore/silcpacket.[ch].
4693 Added silc_server_packet_decrypt_check to the server and
4694 silc_client_packet_decrypt_check to the client library.
4696 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4697 to send with specified source and destination information.
4699 * Channel message delivery between routers was broken after the
4700 channel key distribution was fixed earlier. The channel key
4701 was used be to distributed to other routers as well which is not
4702 allowed by the protocol. Now this is fixed and channel keys
4703 really are cell specific and the channel message delivery between
4704 routers comply with the protocol specification.
4706 * Fixed various commands in server to check also the global list
4707 for the channel entry and not just the local list. The affected
4708 file silcd/command.c.
4710 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Added assert()s to buffer formatting and unformatting routines
4713 to assert (if --enable-debug) when error occurs. Affected
4714 file: lib/silcutil/silcbuffmt.c.
4716 * Changed to auto-reconnect to check whether the remote host is
4717 router and register the re-connect timeout if it is. It used
4718 to check that whether we are normal server, but router must do
4719 auto-reconnect with another router as well. Affected file
4722 * Removed the [<key len>] option from CMODE command as the cipher
4723 name decides the key length, nowadays. See the defined ciphers
4724 from the protocol specification.
4726 * Added [<hmac>] option to the CMODE command to define the HMAC
4727 for the channel. Added SILC_CMODE_HMAC channel mode.
4729 * Added [<hmac>] option for the JOIN command so that user can
4730 select which HMAC is used to compute the MACs of the channel
4733 * Added Hmac field to the Channel Message Payload. The integrity
4734 of plaintext channel messages are now protected by computing
4735 MAC of the message and attaching the MAC to the payload. The
4736 MAC is encrypted. Now, it is clear that this causes some
4737 overhead to the size of the packet but rationale for this is that
4738 now the receiver can verify whether the channel message decrypted
4739 correctly and also when private keys are set for the channel the
4740 receiver can decrypt the packet with several keys and check from
4741 the MAC which key decrypted the message correctly.
4743 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4744 lib/silccrypt/silccipher.[ch].
4746 * Added silc_hash_len to return the digest length into the
4747 lib/silcrypt/silchash.[ch].
4749 * Rewrote parts of Silc Channel Payload interface in the
4750 lib/silccore/silcchannel.[ch]. The encode function now also
4751 encrypts the packet and parse function decrypts it.
4753 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Fixed a minor formatting bug in the SKE's key material processing.
4756 It actually might have processed the keys wrong way resulting
4759 * Redefined the mandatory HMAC algorithms and added new algorithms.
4760 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4761 and hmac-md5 truncated to 96 bits. The mandatory is now
4762 hmac-sha1-96. Rest are optional (including the one that used
4763 to be mandatory). Rationale for this is that the truncated HMAC
4764 length is sufficient from security point of view and can actually
4765 make the attack against the HMAC harder. Also, the truncated
4766 HMAC causes less overhead to the packets. See the RFC2104 for
4769 * Added new [hmac] configuration section. The SKE used to use
4770 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4771 is of course wrong. The official names that must be proposed in
4772 the SKE are the ones defined in the protocol specification
4773 (hmac-sha1-96 for example). The user can configure any hmac
4774 using any hash function configured in the [hash] section. At
4775 least, the mandatory must be configured.
4777 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4779 * Added HMAC list to the SKE proposal list. It has now both
4780 hash algorithm list and HMAC list. This makes the protocol
4781 incompatible with previous versions. The SKE now seems to work
4782 the way it is supposed to work, for the first time actually.
4784 * Defined plain Hash algorithms to the protocol specification.
4787 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Implemented support for key agreement packets into the server.
4790 Added functions silc_server_key_agreement and
4791 silc_server_send_key_agreement. Other than these functions,
4792 server has nothing to do with this packet.
4794 * Added support for private message key packets into the server.
4795 Added functions silc_server_private_message_key and
4796 silc_server_send_private_message_key.
4800 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4801 called in the protocol's final callback instead in the END
4802 protocol state. This makes a little more sense and in the same
4803 time in client we can use the same protocol routines for normal
4804 key exchange and to key agreement packet handling as well.
4806 * Added to both client's and server's KE protocol context the
4807 SilcSKEKeyMaterial pointer to save the key material. We will
4808 bring the key material to the protocol's final callback by doing
4809 this. The final callback must free the key material.
4811 * Added SKE's packet_send callback into client's KE protocol
4812 context so that the caller can choose what packet sending function
4813 is used. This way we can use different packet sending when
4814 doing normal SKE when doing key agreement packet handling (in
4815 the key agreement packet handling we do not want to encrypt
4818 * Implemented the responder side of the key agreement routines
4819 in the client. The client can now bind to specified port and
4820 accept incoming key negotiation. The key material is passed
4821 to the application after the protocol is over.
4823 * Implemented the processing of incoming Key Agreement packet
4824 in the client. Added function silc_client_key_agreement to
4827 * Implemented the intiator side of the key agreement routines
4828 in the client. The client can now initiate key agreement with
4829 another remote client. The key material is passed to the
4830 application after the protocol is over.
4832 * Created client_keyagr.c to include all the key agreement
4835 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4836 SILC_TASK_CALLBACK except that it is not static.
4838 * Created client_notify.c and moved the Notify packet handling
4839 from the client.[ch] into that file.
4841 * Created client_prvmsg.c and moved all private message and
4842 private message key routines from the client.[ch] into that file.
4844 * Create client_channel.c and moved all channel message and
4845 channel private key routines from the client.[ch] into that file.
4847 * Changed silc_client_get_client_by_id_resolve to resolve with
4848 WHOIS command instead of IDENTIFY command, in the file
4849 lib/silclient/idlist.c.
4851 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4853 * Implemented the SKE's responder side to the Client library.
4855 * When FAILURE is received to the protocol do not trust it
4856 blindly. Register a timeout to wait whether the remote closes
4857 the connection as it should do it, only after that process the
4858 actual failure. This was changed to both client and server.
4860 * Added client_internal.h to include some of the structures
4861 there instead of client.h in lib/silcclient/.
4863 * Added function silc_task_unregister_by_callback to unregister
4864 timeouts by the callback function.
4866 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Some "Incomplete WHOIS info" errors has been appearing on the
4869 log files. Took away the entry->userinfo check from WHOIS
4870 reply sending. The entry->userinfo is now " " if client did not
4871 provide one. I thought this was fixed earlier but something
4872 is wrong still. Let's see if the error still appears.
4874 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4876 * Fixed a minor bug in the login when the channel key is
4877 re-generated in the server. It used to generate the key in
4878 wrong order and thus caused problems in the channel traffic.
4880 * Fixed a minor bug in channel key distsribution after
4881 KICK command. The key was not sent to the router even though
4884 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added silc_ske_process_key_material_data as generic routine
4887 to process any key material as the SILC protocol dictates. The
4888 function is used by the actual SKE library but can be used by
4889 applications as well. This relates to the private message keys
4890 and the channel private keys since they must be processed the
4891 same way the normal SILC session keys. The protocol dictates
4892 this. Affected files: lib/silcske/silcske.[ch].
4894 Added also silc_ske_free_key_material to free the
4895 SilcSKEKeyMaterial structure.
4897 * Defined silc_cipher_set_key function to set the key for
4898 cipher without using the object's method function. The affected
4899 files: lib/silccrypt/silccipher.[ch].
4901 * Implemented silc silc_client_add_private_message_key,
4902 silc_client_add_private_message_key_ske,
4903 silc_client_del_private_message_key,
4904 silc_client_list_private_message_keys and
4905 silc_client_free_private_message_keys functions in the
4908 Added functions silc_client_send_private_message_key to send
4909 the Private Message Key payload and silc_client_private_message_key
4910 to handle incoming Private Message Key payload.
4912 * Added Cipher field to the Private Message Key payload to set
4913 the cipher to be used. If ignored, the default cipher defined
4914 in the SILC protocol (aes-256-cbc) is used.
4916 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * Removed lib/silcclient/ops.h file.
4920 Redefined parts of the SILC Client Library API. Created new
4921 file silcapi.h that deprecates the ops.h file and defines the
4922 published Client Library API. Defined also private message key
4923 API and channel private key API into the file.
4925 This is the file that the application must include from the
4926 SILC Client Library. Other files need not be included by
4927 the application anymore.
4929 * Added new key_agreement client operation callback and also
4930 defined the Key Agreement library API for the application.
4932 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4935 is used by clients to request key negotiation between another
4936 client in the SILC network. If the negotiation is started it
4937 is performed using the SKE protocol. The result of the
4938 negotiation, the secret key material, can be used for example
4939 as private message key.
4941 Implemented the Key Agreement payload into the files
4942 lib/silccore/silauth.[ch].
4944 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4946 * Redefined ciphers for the SILC protocol. Added some new ciphers
4947 and defined the key lengths for the algorithms. Changed the
4948 code accordingly. The default key length is now 256 bits.
4950 * Fixed SKE key distribution function silc_ske_process_key_material
4951 when the key length is more than 128 bits. The default key
4952 length in SILC is now 256 bits.
4954 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4955 to indicate unsupported algorithm.
4957 * Renamed rijndael.c to aes.c and all functions as well.
4959 * Fixed a long standing channel key setting bug in client library.
4960 Weird that it has never surfaced before.
4962 * Fixed bug in channel deletion. If the entire channel is removed
4963 then it must also delete the references of the channel entry
4964 from the client's channel list as the client's channel entry and
4965 the channel's client entry share same memory.
4967 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Implemented CONNECT and SHUTDOWN commands in the client.
4971 * Implemented CLOSE command to the client.
4973 * Added the function silc_idlist_find_server_by_name into the
4974 files silcd/idlist.[ch].
4976 Added the function silc_idlist_find_server_by_conn into the
4977 files silcd/idlist.[ch].
4979 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4981 * DIE command was renamed to SHUTDOWN. Updated the both code
4984 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4985 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4987 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4990 * Added function silc_server_create_connection function to create
4991 connection to remote router. My server implementation actually
4992 does not allow router to connect to normal server (it expects
4993 that normal server always initiates the connection to the router)
4994 so the CONNECT command is only good for connecting to another
4997 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4999 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5000 or some other client was kicked from the channel.
5002 Implemented the handling of the notify type to both client
5005 Implemented silc_server_send_notify_kicked to send the KICKED
5006 notify. It is used to send it to the server's primary router.
5008 * Implemented the KICK command into server and client.
5010 * Added `query' argument to the silc_idlist_get_client function
5011 to indicate whether to query the client from server or not if
5014 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5015 to indicate that the client is not channel founder.
5019 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Removed the rng context from SilcPacketContext structure and
5022 changed that the packet routine uses the Global RNG API.
5024 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Added support for quit message that client can "leave" on the
5027 channel when it quits the SILC. It is ditributed inside the
5028 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5030 Added silc_server_free_client_data that will take the
5031 signoff message as argument.
5033 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5035 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5037 * Updated parts of the protocol specification to keep it up
5040 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5043 payloads in one packet.
5045 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5046 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5047 use now the new List flag.
5049 * Also deprecated the following packet types: REPLACE_ID,
5050 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5052 * Added list support for Notify packet in server.
5054 * Added silc_server_send_notify_channel_change to send the
5055 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5056 the silc_server_send_replace_id.
5058 * Added silc_server_send_notify_nick_change to send the
5059 NICK_CHANGE notify type. Deprecates the function
5060 silc_server_send_replace_id.
5062 * Added silc_server_send_notify_join to send the JOIN notify type.
5063 Deprecates the function silc_server_send_new_channel_user.
5065 * Added silc_server_send_notify_leave to send LEAVE notify type.
5066 Deprecates the function silc_server_send_remove_channel_user.
5068 * Added silc_server_send_notify_cmode and
5069 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5070 types. Deprecates the silc_server_send_set_mode function.
5072 * Added SERVER_SIGNOFF notify type to indicate that server has
5073 quit. This means that all clients on the channel from that
5074 server will drop. This can be also used when netsplit happens.
5076 Deprecated REMOVE_ID packet type since it is not needed anymore
5079 Added silc_server_send_notify_server_signoff to send the
5080 SERVER_SIGNOFF notify type. Deprecates the function
5081 silc_server_send_remove_id.
5083 Added also silc_server_send_notify_signoff to send the
5084 SIGNOFF notify type.
5086 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5087 SILC protocol from this day on. Changed the protocol
5088 specification as well.
5090 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5091 notify type. It is used between routers to notify about
5092 topic changes on a channel.
5094 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5097 * Partly updated the protocol specification to comply with the
5098 changes now made. It is still though a bit outdated.
5100 * The JOIN notify type now takes one extra argument <Channel ID>.
5101 The packet used to be destined to the channel but now the
5102 JOIN type may be sent as list thus it is impossible to
5103 destine it to any specific channel. By adding this argument
5104 it is again possible.
5106 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Added CREDITS file. The CHANGES and CREDITS file will appear
5109 in the distribution as well.
5111 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5114 types in the server's silcd/packet_receive.c.
5116 * Implemented CMODE and CUMODE to work in router environment.
5118 * Fixed minor encoding and decoding buglet from the
5119 lib/silccore/silcmode.c.
5121 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5124 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5126 * Changed all SilcConfigServer* and silc_config_server* to
5127 SilcServerConfig* and silc_server_config*, respectively.
5130 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Associated the ID (client or server ID) to the Authentication
5133 Payload to avoid any possibility of forging. Updated the
5134 protocol specification and the code accordingly.
5136 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * The RSA key length is now save to the RsaKey context in the
5139 key generation process in lib/silccrypt/rsa.c. The key length
5140 is now used to figure out the maximum size of the block allowed
5141 to be encrypted/signed.
5143 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5144 is equivalent to the silc_mp_mp2bin but does not allocate any
5147 * Changed silc_mp_mp2bin API to take length argument. If it is
5148 non-zero then the buffer is allocated that large. If zero, then
5149 the size is approximated using silc_mp_sizeinbase, which however
5152 * Created Global RNG API which is global RNG that application can
5153 initialize. After initializing, any routine anywhere in the
5154 code (including library) can use RNG without allocating a new
5155 RNG object. This was done to allow this sort of use of the
5156 RNG in code that has no chance to allocate RNG object. All
5157 applications currently allocate this and many routines in the
5158 library use this. Affected file lib/silccrypt/silcrng.[ch].
5160 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5161 it to use the Global RNG API.
5163 * Defined Authentication Payload into protocol specification that
5164 is used during SILC session to authenticate entities. It is
5165 used for example by client to authenticate itself to the server
5166 to obtain server operator privileges.
5168 Implemented this payload into the lib/silccore/silcauth.[ch].
5169 Implemented also routines for public key based authentication
5170 as the new protocol specification dictates.
5172 Moved definitions of different authentication methods from
5173 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5175 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5176 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5177 silc_pkcs_verify_with_hash functions into the file
5178 lib/silccrypt/silcpkcs.[ch].
5180 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * The client entry's userinfo pointer must be always valid.
5183 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5184 will fail since it requires the userinfo. Now, the userinfo
5185 is allocated as "" if actual userinfo does not exist. Actually,
5186 it must exist and it is totally Ok to drop client connections
5187 that does not announce the userinfo. However, we will make
5188 this workaround for now.
5190 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5191 to return the remote port by socket.
5193 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5196 SILC_SERVER_PENDING_EXEC and added an new macro
5197 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5198 data or when error occurs while processing the pending command.
5200 Added new argument `destructor' into silc_server_command_pending
5201 and to the SilcServerCommandPending object. This destructor is
5202 now called after calling the pending callback or if error occurs
5203 immediately. If error occurs the actual pending callback won't
5204 be called at all - only the destructor. The destructor may be
5205 NULL if destructor is not needed.
5207 All this applies for client library code as well. Similar
5208 changes were made there as well for the pending commands.
5210 In the client, the application must now allocate the
5211 SilcClientCommandContext with the silc_client_command_alloc
5214 * Added reference counter to the SilcServerCommandContext. Added
5215 function silc_server_command_alloc and silc_server_command_dup
5218 Same type of functions added to the client library for the same
5221 * Removed the cmd_ident from IDListData away since it is now
5222 global for all connections. It is the command identifier used
5223 in command sending and with pending commands. The affected file
5226 * Added reference counter to the SilcSocketConnection objecet to
5227 indicate the usage count of the object. The object won't be
5228 freed untill the reference counter hits zero. Currently only
5229 server uses this, and client ignores it. The client must be
5230 set to use this too later. The affected files are
5231 lib/silccore/silcsockconn.[ch]. Added also the function
5232 silc_socket_dup to increase the reference counter.
5234 This was mainly added because it is possible that the socket
5235 is removed underneath of pending command or other async
5236 operation. Now it won't be free'd and proper DISCONNECTING
5237 flags, etc. can be set to avoid sending data to connection that
5238 is not valid anymore.
5240 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5241 the connection. After that it sets SILC_SET_DISCONNECTED.
5242 It is, however, possible that the socket data is not still freed.
5243 The silc_server_packet_process now checks that data is not
5244 read or written to connection that is DISCONNECTED. The socket
5245 get's freed when the reference counter hits zero.
5247 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Changed the client operation API: channel_message operation's
5250 `sender' is now the client entry of the sender, not the nickname
5251 and the `channel' is the channel entry, not the channel name.
5253 In the private_message operation the `sender' is now also the
5254 client entry of the sender not the nickname.
5256 Affected file is lib/silcclient/ops.h and all applications
5257 using the client operations.
5259 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Moved the calling of ops->connect() from connect_to_server_final
5262 into receive_new_id functin since that is the point when the
5263 client is actually allowed to send traffic to network. The
5264 affected file is lib/silcclient/client.c.
5266 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5269 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5270 (if needs broadcasting) instead of broadcasting the packets one
5271 by one which would make a burst in the network traffic.
5273 * Added `broadcast' argument to the functions in silcd/server.[ch]
5274 silc_server_create_new_channel[_with_id] to indicate whether
5275 to send New Channel packet to primary router.
5277 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * Added new function into the silcd/server.[ch] files:
5280 silc_server_create_new_channel_with_id to create new channel with
5281 already existing Channel ID.
5283 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5284 lib/silccore/silcpacket.h. This packet is used t send list of
5285 Set Mode payloads inside one packet. Server uses this to set
5286 the modes for the channels and clients on those channels, that it
5287 announced to the router when it connected to it. The protocol
5288 specification has been updated accordingly.
5290 * The silc_server_new_channel did not handle the packet coming
5291 from normal server as it normally does not send that. However,
5292 when it announces its channels it does send it. Implemented
5293 the support for that.
5295 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5296 into the file lib/silccore/id.h.
5298 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Fixed memory leaks in the functions silc_idlist_del_client,
5301 silc_idlist_del_channel and silc_idlist_del_server in the file
5302 silcd/idlist.c. All of those leaked like a sieve.
5304 * Fixed some small memory leaks in the client's function
5305 silc_client_notify_by_server.
5307 * Added functions into silcd/server.c: silc_server_announce_clients,
5308 silc_server_announce_channels and silc_server_announce_server.
5309 These functions are used by normal and router server to announce
5310 to its primary router about clients, channels and servers (when
5311 router) that we own. This is done after we've connected to the
5314 These functions effectively implements the following packet types:
5315 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5316 and SILC_PACKET_NEW_ID_LIST.
5318 * Added new functions into the silcd/packet_receive.[ch]:
5319 silc_server_new_id_list, silc_server_new_channel_list and
5320 silc_server_new_channel_user_list to handle the incoming
5321 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5323 * Added support of changing Channel ID in the function
5324 silc_server_replace_id. If the server that announces a channel
5325 to the router already exists in the router (with same name but
5326 with different Channel ID), router is responsible to send
5327 Replace ID packet to the server and force the server to change
5328 the Channel ID to the one router has.
5330 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5331 client that the Channel ID has been changed by the router. The
5332 normal server sends this to the client. Client must start using
5333 the new Channel ID as the channel's ID.
5335 Implemented handling of this new type into lib/silcclient/client.c
5336 into the function silc_client_notify_by_server.
5338 * Added new function silc_idlist_replace_channel_id into the files
5339 silcd/idlist.[ch] to replace the Channel ID.
5341 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Call silc_server_command_identify_check always when processing
5344 the IDENTIFY command in silcd/command.c
5346 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5349 send keepalive packets. The packet can be sent by clients,
5350 servers and routers.
5352 Added function silc_socket_set_heartbeat into the file
5353 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5354 If not set, the heartbeat is not performed. The actual
5355 heartbeat is implemented in the low level socket connection
5356 library. However, application is responsible of actually
5359 Added silc_server_send_heartbeat to send the actual heartbeat
5360 packet into silcd/packet_send.[ch]. Server now performs
5361 keepalive with all connections.
5363 * Added silc_task_get_first function into lib/silcutil/silctask.c
5364 to return the timeout task with shortest timeout. There was a bug
5365 in task unregistration that caused problems. TODO has been
5366 updated to include that task system must be rewritten.
5368 * The client library will now resolve the client information when
5369 receiving JOIN notify from server for client that we know but
5370 have incomplete information.
5372 * Rewrote parts of silc_server_remove_from_channels and
5373 silc_server_remove_from_one_channel as they did not remove the
5374 channel in some circumstances even though they should've.
5376 * Encryption problem encountered in server:
5378 The LEAVE command used to send the Channel Key packet to the
5379 router immediately after generating it. However, the code
5380 had earlier sent Remove Channel user packet but not immediately,
5381 ie. it was put to queue. The order of packets in the router
5382 was that Channel Key packet was first and Remove Channel User
5383 packet was second, even though they were encrypted in the
5384 reverse order. For this reason, MAC check failed. Now, this
5385 is fixed by not sending the Channel Key packet immediately but
5386 putting it to queue. However, this is more fundamental problem:
5387 packets that are in queue should actually not be encrypted
5388 because packets that are sent immediately gets encrypted
5389 actually with wrong IV (and thus MAC check fails). So, packets
5390 that are in queue should be encrypted when they are sent to
5391 the wire and not when they put to the queue.
5393 However, the problem is that the current system has not been
5394 designed to work that way. Instead, the packet is encrypted
5395 as soon as possible and left to the queue. The queue is then
5396 just purged into wire. There won't be any fixes for this
5397 any time soon. So, the current semantic for packet sending
5400 o If you send packet to remote host and do not force the send
5401 (the packet will be in queue) then all subsequent packets to the
5402 same remote host must also be put to the queue. Only after the
5403 queue has been purged is it safe again to force the packet
5406 o If you send all packets immediately then it safe to send
5407 any of subsequent packets through the queue, however, after
5408 the first packet is put to queue then any subsequent packets
5409 must also be put to the queue.
5411 Follow these rules and everything works fine.
5413 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Added new function silc_server_remove_clients_by_server to
5416 remove all client entries from ID list when the server connection
5417 is lost. In this case it is also important to invalidate all
5418 client entires as they hold the invalid server entry. This
5419 fixes fatal bug when server has lost connection and will reconnect
5422 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Made some sanity checks to silc_server_daemonise like to check
5425 whether the requested user and group actually exists.
5427 * Added sanity check to SKE's silc_ske_responder_finish to check
5428 that the public and private key actually is valid.
5430 * Invalidate the client's nickname when receiving Replace ID
5431 packet and the Client ID is being replaced. This means that the
5432 server will query the nickname if someone needs it (client)
5435 * Sort the ID Cache in client library when the ID Cache data
5436 has changed (needs sorting).
5438 * Do not allow for SILC client to create several connections to
5439 several servers. The client does not support windows right now
5440 and generating multiple connections causes weird behaviour.
5442 Irssi-silc client does support windows and can handle several
5443 connections without problems, see: www.irssi.org and SILC plugin.
5445 * Fixed some places where client was added to the IDList. The
5446 rule of thumb is following (in order to get everything right):
5447 If the client is directly connected local client then the
5448 `connection' argument must be set and `router' argument must be
5449 NULL to silc_idlist_add_client function. If the client is not
5450 directly connected client then the `router' argument must
5451 bet set and the `connection' argument must be NULL to the
5452 silc_idlist_add_client function.
5454 * The funtion silc_server_packet_send_local_channel actually did
5455 not check whether the client was locally connected or not. It
5456 does that now. Fixed a bug related to LEAVE command.
5458 * Fixed Remove Channel User payload parsing bug in server's
5459 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5461 * The server's silc_server_save_channel_key now checks also the
5462 global ID list for the channel as it might not be in the local
5463 list. Fixed a bug related to LEAVE command.
5465 * Is this the end of the [<unknown>] buglet that has been lurking
5466 around for a long time? A little for loop fix in server's
5467 silc_server_command_whois_parse that is used by both IDENTIFY
5468 and WHOIS command. At least, this was a clear bug and a cause
5469 of one type of [<unknown>] buglet.
5471 * WHOIS and IDENTIFY commands call the function
5472 silc_server_command_[whois/identify]_check function even if
5473 we are not router server.
5475 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5477 * Added --with-gmp configuration option. If set the GMP
5478 is always compiled in the SILC source tree. If not set then
5479 it is checked whether the system has the GMP3 installed. If
5480 it has then the GMP won't be compiled (the system's headers
5481 and library is used), if it doesn't have it then the GMP is
5482 compiled in the SILC source tree.
5484 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Changed RSA private exponent generation to what PKCS #1
5487 suggests. We try to find the smallest possible d by doing
5488 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5489 not security fix but optimization.
5491 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Added new config entry [Identity] to fork the server and run
5494 it as specific user and group. A patch from Bostik.
5496 * Imported Dotconf configuration library into lib/dotconf.
5497 This will be used to create the SILC configuration files later.
5498 It will appear in the distsribution after this commit.
5500 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * A big code auditing weekend happening. Auditing code for
5503 obvious mistakes, bugs and errors. Also, removing any code
5506 Removed files for being obsolete:
5508 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5509 inline in the file lib/silcutil/silcbuffer.h)
5511 o lib/silcutil/silcbufutil.c (the header has inline versions)
5513 Changed code to fix possible error conditions:
5515 o The buffer formatting routines now check that the destination
5516 buffer really has enough space to add the data. This applies for
5517 both buffer formatting and unformatting
5518 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5519 unformatting was changed to accomodate following rules:
5520 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5521 sent to the function while XXX_*STRING will not allocate or copy
5522 the data into the buffer. Instead it sets the pointer from the
5523 buffer into the pointer sent as argument (XXX_*STRING used to
5524 require that the pointer must be allocated already). This change
5525 makes this whole thing a bit more consistent and more optimized
5526 (note that the data returned in the unformatting with XXX_*STRING
5527 must not be freed now). The routines return now -1 on error.
5529 o Tried to find all code that use buffer_format and buffer_unformat
5530 and added return value checking to prevent formatting and
5531 especially unformatting errors and possible subsequent fatal
5534 o Changed ske->x and ske->KEY to mallocated pointers in
5535 lib/silcske/silcske.h. Fixed possible data and memory leak.
5537 o Added return value checking to all *_parse* functions. Fixed
5538 many memory leaks as well.
5540 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5541 so that buffer overflows would not happen. All code now also
5542 checks the return value as it can fail.
5544 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Added reconnection support to server if the normal server looses
5547 its connection to the router (for example if router is rebooted).
5548 The server performs normal reconnection strategy implemented
5549 to the server. Affected file silcd/server.c.
5551 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Added new packet type SILC_PACKET_SET_MODE that is used to
5554 distribute the information about changed modes (for clients,
5555 channels and clients channel modes) to all routers in the
5556 network. Updated the protocol specification accordingly.
5558 Added functions into silcd/packet_send.c and
5559 silcd/packet_receive.c: silc_server_send_set_mode,
5560 silc_server_set_mode.
5562 Added new files silcmode.[ch] into lib/silccore that implements
5563 the encoding and decoding of Set Mode Payload. Added new type
5564 SilcSetModePayload. Moved the definitions of different modes
5565 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5567 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5569 * Oops, a little mistake in server's connection authentication
5570 protocol. The protocol is not ended with FAILURE but with
5571 SUCCESS if the authentication is Ok. :) Affected file is
5574 * Implemented NICK_CHANGE notify handling in server in the file
5575 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5576 the local clients on the channel. After the changing nickname
5577 in router environment snhould work and the [<unknown>] nickname
5578 should appear no more.
5580 The silc_server_replace_id function that receives the Replace ID
5581 payload now sends the NICK_CHANGE notify type also in the file
5582 silcd/packet_receive.c
5584 * Changed WHOIS and IDENTIFY command to support the maximum amount
5585 of arguments defined in protocol specs (3328 arguments). This
5586 fixed a bug that caused problems when there were more than three
5589 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5591 * Added extra parameter, command identifier, to the
5592 silc_client_send_command so that explicit command identifier
5595 Changed that ID list routines uses specific command identifier
5596 when sending WHOIS/IDENTIFY requests to the server so that they
5597 can be identified when the reply comes back.
5599 Affected files lib/silcclient/command.[ch],
5600 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5602 * Added `sender' argument to silc_server_packet_send_to_channel
5603 to indicaet the sender who originally sent the packet to us
5604 that we are now re-sending. Ignored if NULL. Affected file
5605 silcd/packet_send.[ch].
5607 * Added some server statistics support in silcd/server_internal.h
5608 SilcServerStatistics structure and around the server code. Also
5609 send some nice statistics information when client is connecting
5612 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Fixed channel ID decoding in server's JOIN command reply in
5615 silcd/command_reply.c
5617 * Fixed braodcasting of replace ID payload to not to send it if
5618 we are standalone server in silcd/packet_receive.c.
5620 * Fixed all channel message sending routines to not to send
5621 packets to clients that has router set, since they are routed
5622 separately in the same function earlier. Affects file
5623 silcd/packet_send.c and all channel packet sending functions.
5625 * In USERS reply, res_argv[i] are not allocated, the table
5626 is allocated. Thus changed that free the table, not its
5629 * In server's whois_check and identify_check if the client is
5630 locally connected do not send any WHOIS commands - they are not
5633 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Fixed some minor bugs in client when sending WHOIS command. The
5636 arguments was in wrong order.
5638 * Removed statis function add_to_channel from server in
5639 silcd/command.c that was previously used with the joining but
5642 * Tested USERS command in router environment successfully with two
5643 routers, two servers and two clients.
5645 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Reorganized the USERS command and command reply in client library
5648 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5649 When the command is given by user we register a pending command
5650 callback that will reprocess the command after the reply has been
5651 received from the server. When reprocessing the packet we then
5652 display the information. Thus, the USERS information is displayed
5653 now in the command callback instead of in the command reply
5654 callback. The processing of the command is same as previously
5655 when server has sent the command reply in the JOINing process.
5657 * Added to USERS command in silcd/command_reply.c to join the client,
5658 we didn't use to know about, to the channel after we've created
5659 a client entry for it. Also, for clienet we did know already still
5660 check whether it is on the channel or not and add it if not.
5662 * Removed silc_server_command_join_notify as the function and its
5665 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Changed the client's pending command handling to the same as the
5668 server's pending command handling. It is also now possible to
5669 execute command reply functions from other command reply
5670 function as the function callbacks for commands and command
5671 replies are one and same. The pending commands are not static
5672 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5673 in client connection context. Thus, pending commands are server
5674 connection specific as it is convenient.
5676 Changed the function silc_client_command_pending and
5677 silc_client_command_pending_del and added new function
5678 silc_client_command_pending_check. Removed the
5679 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5682 * Added cmd_ident, current command identifier, to the client
5683 connection context in lib/silcclient/client.h to keep track on
5684 command identifiers used in command sending. Client's command reply
5685 function handling now supports the mandatory command identifiers.
5687 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5688 funtions in client to fully support pending command callbacks.
5690 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5691 as one of the arguments to the application in the command reply
5694 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5695 before first releasing SILC but came back. Now it is removed again
5696 and should come back nomore. The FORWARDED flag was used only
5697 by the JOINing procedure by forwarding the command packet to router.
5698 Now, the JOINing procedure has been changed to more generic (due
5699 to various router environment issues) and FORWARDED is not needed
5700 anymore for anything. The protocol specification is yet to be
5703 Now, removed silc_server_packet_forward from server and the flag
5704 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5706 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Renamed NAMES command to USERS command. The NAMES was named that
5709 due to historical reasons. Now it is renamed. Also, rewrote
5710 parts of the USERS command. The nickname list is not sent anymore
5711 by the server. Only Client ID and mode lists are sent in the USERS
5712 command. Changed this also to the protocol specification.
5714 The client now resolves the names and stuff after it receives
5715 the USERS list from the server when joining to the channel.
5717 * WHOIS and IDENTIFY commands has been changed to support multiple
5718 Client ID's per command. One can now search for multiple users
5719 in the network by sending only one WHOIS or IDENTIFY command.
5720 Changed the code and the protocol specifications.
5722 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5723 uses silc_server_command_whois_parse to parse the request. */
5725 * If normal server, do not parse the WHOIS and IDENTIFY requests
5726 before sending it to the router. Saves some time.
5728 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * Fixed JOIN command on client library. Wrong number of arguments
5731 used to crash the client.
5733 * Added silc_server_channel_has_global function to check whether
5734 channel has global users or not.
5736 * Added silc_server_channel_has_local function to check whether channel
5737 has locally connected clients on the channel.
5739 * The silc_server_remove_from_one_channel now checks whether the
5740 channel has global users or not after given client was removed from
5741 the channel. It also checks whether the channel has local clients
5742 on the channel anymore. If it does not have then the channel entry
5743 is removed as it is not needed anymore.
5745 * The silc_server_notify now checks on JOIN notify whether the joining
5746 client is one of locally connected or global. If it is global then
5747 the channel has now global users on the channel and that is marked
5748 to the channel entry. Also, it now saves the global client to
5749 global list who is joining and JOINs it to the channel. This is
5750 for normal server, that is.
5752 Changed silc_server_send_notify_on_channel,
5753 silc_server_packet_relay_to_channel and
5754 silc_server_packet_send_to_channel check if we are normal server
5755 and client has router set (ie. global client) do not send the
5756 message to that client, as it is already routed to our router.
5758 * Implemented LEAVE notify type handling in silc_server_notify
5761 * Tested LEAVE command in router environment successfully. Tested
5762 with two routers, two servers and two clients.
5766 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5768 * Implemented SIGNOFF notify type handling in silc_server_notify
5771 * silc_server_remove_id now removes the client entry from all channels
5772 it has joined and thusly sends SIGNOFF notify type.
5774 * Rewrote the NAMES list generation in server by removing two excess
5775 loops. The lists are created now inside one loop.
5777 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * silc_server_remove_channel_user checks now also global list
5780 for channel and client.
5782 * silc_server_new_channel_user checks now both local and global
5783 list for channel and client. Fixed a bug in client id decoding.
5784 Used to decode wrong buffer.
5786 * silc_server_channel_message checks now both local and global
5787 list for channel entry.
5789 * Tested channel joining (hence JOIN) in router environment
5790 successfully. Tested with two routers, two servers and two
5793 * Tested channel message sending in router environment successfully.
5795 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Added silc_server_save_channel_key into server.[ch] to save the
5798 received channel key in Channel Key payload processing. It is
5799 also used in JOIN command reply handling.
5801 Equivalent function silc_client_save_channel_key added into
5802 client.[ch] into client library.
5804 * Changed JOIN command reply to send information whether the channel
5805 was created or not (is existing already) and the channel key
5806 payload. Changed protocol specs accordingly.
5808 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5809 the request was sent by ID and not by nickname. Crashed on
5812 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5815 now correctly save the received data.
5817 * silc_server_free_sock_user_data now notifies routers in the
5818 network about entities leaving the network.
5820 At the same time implemented functions silc_server_remove_id
5821 and silc_server_send_remove_id to receive and send REMOVE_ID
5822 packets. The packet is used to notify routers in the network
5823 about leaving entities. The ID removed will become invalid in
5826 * Added function silc_idlist_del_server into server. Removes and
5827 free's server entry from ID list.
5829 * silc_server_private_message function now checks, if we are router,
5830 that the destination ID really is valid ID, naturally.
5832 * In router when NEW_ID packet is received (for new client) the
5833 hash of the Client ID is saved in the ID Cache but the
5834 client->nickname is set to NULL, instead of putting the hash
5837 IDENTIFY command now also checks that client->nickname must be
5838 valid. If it is not if will request the data from the server who
5839 owns the client. Added new function
5840 silc_server_command_identify_check.
5842 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5843 to set the command to already allocated Command Payload.
5845 * Tested private message sending in router environment with two
5846 routers, two servers and two clients. Fixed minor bugs and now
5849 * Fixed segfault from client's NAMES command. Used to crash if
5852 * Forwarded packets must not be routed even if it is not destined
5853 to the receiver. Changed server code comply with this.
5855 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Added `require_reverse_mapping' boolean value to ServerParams
5858 structure. If TRUE (not default) the server will require that
5859 the connecting host has fully qualified domain name.
5861 If the reverse mapping is not required and hostname could not be
5862 found the IP address is used as hostname.
5864 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Implemented version string checking to both client and server.
5867 The check is incomplete currently due to the abnormal version
5868 strings used in development version of SILC.
5870 * Changed all command functions in server to use the new
5873 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Changed char *data to unsigned char *data in ID Cache system to
5876 support binary data as ID Cache data. Changed code to support
5877 binary data in lib/silccore/idcache.c.
5879 * Renamed silc_server_packet_relay_command_reply to
5880 silc_server_command_reply as it is normal packet receiving
5881 function. Rewrote the function to accept command replys for
5882 servers and not only for clients.
5884 * Mark remote router always as registered server if we are connecting
5885 to it. Otherwise, commands sent by the router to us are ignored.
5887 * All ID List find routines now returns the ID Cache Entry pointer
5888 as well if requested.
5890 * WHOIS command works now in router environment, tested with two
5891 routers, two servers and two clients.
5893 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5894 in router environment (as it is almost equivalent to WHOIS) but
5895 hasn't been tested thoroughly. Added new functions:
5897 silc_server_command_identify_parse
5898 silc_server_command_identify_send_reply
5899 silc_server_command_identify_from_client
5900 silc_server_command_identify_from_server
5902 * Disabled route cache adding because adding two different ID's with
5903 same IP replaces the old cache entry thus giving wrong route.
5904 The entry->router->connection is always the fastest route anyway
5905 so route cache may not be needed. Of course, new routes maybe
5906 established after receiving the ID when the entry->router->connection
5907 might not be anymore the most optimal.
5909 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Add route cache for received ID for fast routing.
5913 * Added silc_server_packet_route to route received packet on router
5914 that is not destined to us.
5916 * Renamed silc_server_get_route to silc_server_route_get.
5918 * Added id_string and id_string_len fields into SilcServer to
5919 include encoded ServerID for fast comparing without excess
5920 encoding of the ID's.
5922 * Cleaned up WHOIS command on server side. Added following static
5925 silc_server_command_whois_parse
5926 silc_server_command_whois_check
5927 silc_server_command_whois_send_reply
5928 silc_server_command_whois_from_client
5929 silc_server_command_whois_from_server
5931 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5932 arguments in command replies. All command functions should be
5933 updated to use this macro.
5935 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * Minor typo fixes on command reply handling on server.
5939 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5941 * Added silc_server_command_add_to_channel internal routine to add
5942 the client to the channel after router has created the channel and
5943 sent command reply to the server.
5945 * Added generic silc_server_send_command to send any command from
5948 * Use static buffer with ID rendering instead of duplicating data.
5950 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5952 * Fixed a channel user mode bug when joining to a channel server gave
5953 everybody channel founder rights, oops.
5955 * We mark ourselves as the router of the incoming server connection
5956 if we are router ourselves. This way we can check in some packet
5957 sending functions whether it is locally connected server. For
5958 incoming router connections we put NULL.
5960 * For router sending packets locally means now always sending the
5961 packet cell wide; to local clients and local servers. For normal
5962 server sending packet locally means sending it to only local
5965 * Fixed the JOIN command to really work in router environment. If the
5966 channel is created it is always created by the router. Router is
5967 also responsible of making the initial joining to the channel,
5968 sending JOIN notify to the sending server and distributing
5969 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5970 does not exist server doesn't do anything else but forward the
5971 command to the router which performs everything.
5973 * Added silc_server_send_channel_key function to send the Channel Key
5976 * Added silc_server_create_channel_key to create new channel key. The
5977 channel key is now re-generated everytime someone joins or leaves
5978 a channel, as protocol dictates. Note: channel->key_len is the
5981 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5983 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5984 packet_receive.[ch] to separate packet sending and receiving
5985 routines. The server.[ch] now includes everything else including
5986 actual packet processing (writing and reading data) and other
5989 Renamed silc_server_private_message_send_internal to
5990 silc_server_send_private_message. The routine is still though
5991 used only to relay private messages as server does not send
5992 private messages itself.
5994 Renamed silc_server_new_channel to silc_server_create_new_channel
5995 and added new function sicl_server_new_channel that handles the
5996 incoming New Channel packet. Added also new sending function
5997 silc_server_send_new_channel to send New Channel Payload.
5999 * Added new function silc_server_notify to process incoming notify
6000 packet to the server/router. Server may then relay the notify
6001 to clients if needed.
6003 * Added new function silc_server_new_channel_user to process incoming
6004 New Channel User packet. Router will redistribute the packet and
6005 send JOIN notify to its local clients and locally connected servers
6006 if needed. Normal server will send JOIN notify to its local client
6007 on same channel when received this packet. Added also corresponding
6008 sending function silc_server_send_new_channel_user to sent the
6011 * Added boolean route argument to send_notif_to_channel and
6012 packet_send_to_channel functions to attempt to route the packet
6013 if it is TRUE and send only locally if it is FALSE.
6015 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * silc_server_replace_id now broadcasts the received replace ID
6018 packet if it is not broadcast packet already. The router must
6019 broadcast to inform other routers about changed ID.
6021 * Added backpointer to server's router into SilcServer context in
6022 silcd/server_internal.h.
6024 * Fixed silc_server_packet_broadcast to send correct broadcast
6027 * The channel key is now distributed to the local client as soon
6028 as it is received from the router (in router environment) so that
6029 no other packet may be sent for the channel until client has
6032 * silc_server_remove_channel_user now broadcasts the received
6033 Remove Channel User packet if it is not broadcast packet already.
6034 The router must broadcast to inform other routers about removed
6037 * Added users field into SilcPacketContext that is a reference count
6038 of the context. One can increase the reference count by calling
6039 silc_packet_context_dup which is now changed to just increase the
6040 reference count instead of duplicating the data. The reference
6041 count is decresed by calling silc_packet_context_free that will
6042 free the data after the reference count hits zero.
6044 For now on the packet context and everything allocated into it
6045 (including the raw packet from network) must be freed by calling
6046 the new silc_packet_context_free function. Added also new function
6047 silc_packet_context_alloc that must be used now to allocate the
6048 context. This also means that if a routine is asynchronous from
6049 silc_[client/server]_packet_parse_type the packet context must
6050 be duplicated by calling silc_packet_context_dup. Otherwise it
6051 gets free'd after silc_[client/server]_packet_parse_type returns.
6052 Also, one must remember that if packet is duplicated then its
6053 reference count must be decresed by calling the free function as
6054 many times as it was duplicated.
6056 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6057 from both client and server.
6059 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Made joining to a channel working in router environment.
6063 * Cleaned up JOIN command on server side and create function
6064 silc_server_command_join_channel internal routine to make the
6067 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * Changed silc_command_pending list to SilcDList. Also, added
6070 `ident' field to SilcServerCommandPending structure to identify
6071 the reply and to call correct callback.
6073 Added silc_server_command_pending_check function to replace the
6074 corresnponding macro. The silc_command_pending list is not
6077 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6078 to set identifier to previously allocated Command Payload. It
6079 is used to set identifier for command when resending Command
6082 * Added silc_command_payload_encode_payload to encode Command
6083 Payload buffer from SilcCommandPayload structure.
6085 * Added silc_argument_payload_encode_payload to encode Argument
6086 payload buffer from SilcArgumentPayload structure.
6088 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Changed WHOIS command to support router connection on server side.
6091 The whois request is always sent to router unless the server is
6092 standalone server. After server has received the reply from the
6093 router will it send the reply to the client.
6095 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6096 broadcast received broadcast packet. The function is used only
6097 by router. The broadcast packet is always sent to the router's
6100 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6101 render given ID to printable string, for log files for example.
6103 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Made basic router to router connections working. At least they
6106 can now connect to each other but nothing really works the way
6107 they are supposed - yet.
6109 * Added new initiator token to RouterConnection configuration
6110 file in silcd/serverconfig.[ch]. It is used to tell whether we
6111 are the initiator to the remote router or whether we'll expect
6112 the other end to connect.
6114 * Moved registering of listener task to silc_server_init, hence
6115 the server starts listenning as soon as it is run, even if it
6116 does not have connections to other routers. Let's see how well
6119 * Changed default connection retry timeouts for more suitable in
6122 * Removed cipher and such arguments from silc_idlist_add_client
6123 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6124 Added new function silc_idlist_add_data to add the keys and stuff
6127 * Added SilcIDListData structure and added it to SilcClientEntry
6128 and SilcServerEntry as their first field in the structure. This
6129 way we can explicitly cast the ID entries to the SilcIDListData
6130 structure and get common data for the entries. In past, we had
6131 to first check what type of connection it is and then cast it to
6132 correct ID entry type. Now, we can directly cast the opaque
6133 pointer to the SilcIDListData (no matter what ID entry it actually
6134 is) and get the data needed.
6136 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6138 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6139 in some circumstances even if threre were timeout tasks, though not
6140 IO tasks, but tasks anyway. Now fixed.
6142 * Defined SilcServerConnection structure to hold connection specific
6143 stuff about directly connected servers and routers. The definition
6144 is currently in silcd/server_internal.h. I thought about having
6145 a bit more important role fro this struct but for now it is used
6146 only when connecting to other server (or router actually).
6148 * Added connecting retry support in server when connecting to
6149 router(s). The retry feature implement exponential backoff
6150 algorithm. Also, added SilcServerParams structure to hold default
6151 parameters for server. For now, it include these retry settings
6152 and are hard coded. After server is moded to be as Silc Server
6153 Library this structure will be more important.
6155 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * Changed client librarys channel->clients table to SilcList and
6158 changed code accordingly.
6160 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Changed client's channel table to SilcList and changed code
6163 accordingly. Also changed SilcChannelClientEntry to include back-
6164 pointer to the channel so that client entry can use that structure
6165 as list as well and we have fast cross-reference to the channel.
6166 This change dramatically decreased the complexity of channel
6167 handling with client entry and vice versa (removed one extra
6168 loop when searching for channel entry from many functions).
6170 * Changed server->sim from table to SilcDList and changed code
6173 * NAMES command can now be used from user interface. It will show
6174 the user list on the channel, neatly.
6176 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6177 Code now saves realname of the user if it becomes available.
6179 * Renamed configure.in to configure.in.pre and made ./prepare
6180 script to automatically add correct version string to
6181 configure.in which it creates from configure.in.pre.
6183 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6185 * NAMES command reply now shows users mode with the nickname when
6188 * Moved silc_client_ch[u]mode[_char] functions from
6189 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6190 place sucks, they are utility functions and should be in some
6193 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6195 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6198 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * Added TRQ (efficient deque and list library) into lib/trq. This is
6203 a very good list library that is currently used in the SILC. Defined
6204 SilcList API over the library because I didn't like the API very
6205 much. See lib/trq/silclist.h for the API and examples of how to
6206 use the API. Fixed various places in the code to use the new
6207 SilcList API. The SilcList is meant for lists that has a structure
6208 already defined as a list. It is not suitable to add just some
6209 context to the list (in TRQ, the context is the list actually).
6211 So, I defined SilcDList that can be used for the purpose where
6212 predefined list structure does not exit. This can be used as
6213 such list. Now some context just can be added to the SilcDList.
6214 Currently this list is not used in the SILC just yet, though there
6215 are a lot places where this can replace dynamically allocated
6216 tables and I will fix these places, later, to use SilcDList.
6217 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6218 and use TRQ internally).
6220 Also fixed some annoying warning messages that the original TRQ
6221 code generated. Also minor changes to TRQ's Makefile.in.
6223 * Added support for querying by Client ID to both WHOIS and
6224 IDENTIFY commands into server, as required by the protocol.
6226 * Removed method function pointers from SilcBuffer structure. They
6227 weren't used to anything and just increased the context size for
6228 no good reason. This change also made silc_buffer_alloc and
6229 silc_buffer_free functions inline functions.
6231 * Disabled command flooding detection support until it's fixed so
6232 that it accepts commands in but does not execute them more than once
6235 * Added silc_net_localhost(), to return local hostname, into
6236 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6237 that must be initialized before calling silc_client_init.
6239 * Added new function: silc_server_send_notify_on_channels to send
6240 notify messages to all channels client has joined. It is assured
6241 that the message is sent only once per client.
6243 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6244 lib/silcutil/silcutil.[ch] as silc_format function. The new
6245 function is generic and is used by server as well, not only by
6246 the logging routines.
6248 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6249 the provided version string was not acceptable. Added new function:
6250 silc_ske_check_version into lib/silcske/silcske.h. The function
6251 must be implemented by the application (client or server) and it
6252 does not reside in the SKE library. The function checks the version
6253 string remote end sent.
6255 * Added back pointers (to opaque context and to SilcSocketConnection)
6256 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6258 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6259 duplicate packet context structure.
6261 * Changed `notify' client operation to send same arguments as client
6262 receives from server except for ID's. ID's are mapped to correct
6263 ID entry and that is returned. Also, if channel entry is not sent
6264 by server but the notify is for channel the channel entry is sent
6265 to application (otherwise application doesn't know that it is for
6266 channel (library gets it from packet's Destination ID)).
6268 * Added silc_client_remove_from_channels into client library to
6269 remove a client from all channels it has joined to. Used when
6270 received SIGNOFF notify from server. Added also new function
6271 silc_client_replace_from_channels to replace old ID entry with
6272 new ID entry on all channels. Used when received NICK_CHANGE
6275 * Fixed ID Cache list handling in silc_idlist_get_client in
6276 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6277 to get (or query) client by ID.
6279 * Updated TODO list.
6281 * Added connection authentication status message defined by the
6282 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6283 support for these into the code in client and server side.
6285 * Added generic function silc_client_send_command to send any command
6286 with variable argument list. Application should use this function
6287 to send commands if the command functions provided by the library
6288 does not suite for the application's user interface needs.
6290 * Added new `failure' client operation. Application is notified about
6291 received failure packet if client is executing a protocol. In this
6292 case the protocol's execution has failed.
6294 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6295 is required by the protocol.
6297 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6298 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6301 * Added status flag to SilcSKE object to indicate realtime status
6302 of the SKE protocol.
6304 * Application receives now exactly same command reply arguments as
6305 the library receives from server. However, if ID is received the
6306 corresponding ID entry is returned to the application (eg. Client
6307 ID is mapped to correct SilcClientEntry entry and that is returned).
6308 Changed command_reply client operation due to this change.
6310 * Changed all ID's in commands and in command replys as ID Payloads.
6311 Change affected both client and server side codes.
6313 All ID's sent in SILC network (with execption of ID's in SILC
6314 Packet header) are sent in ID Payload to support variable length
6317 * Server now notifies nick changes and notifies all clients on
6318 the channels about the new nickname (about the new Client ID,
6321 * Implemented CMODE command to change channel modes. Supports all
6322 channel modes defined by the protocol specs except ban and invite
6323 lists. (Also, private channel key mode is supported but support for
6324 setting private channel key in client is missing, thus, this mode
6325 has no effect on client side (except that server requires that the
6326 client uses private channel key and normal channel traffic does not
6329 Also, invite mode works per se, but INVITE command does not work
6330 yet correctly, so you can set channel as invite only channel but
6331 inviting clients to the channel does not work (it is yet to be
6332 thought what's the best way to do it).
6334 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6335 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6336 Implemented CUMODE command to change user's mode on the channel.
6337 Supports all modes defined by the protocol specs.
6339 * Added NAMES command reply to return users modes on the channel.
6341 * Removed unnecessary and slow ciphers from lib/silccrypt.
6343 * Set SO_KEEPALIVE option to connection sockets by default.
6345 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6347 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6348 redefined the Notify Payload into protocol specs.
6350 * Added silc_id_payload_parse_id to get ID directly from raw
6353 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6356 accept searching by Client ID as well.
6358 * Added support for LEAVE and SIGNOFF notify types in client library.
6360 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6361 to parse ID Payload from raw data.
6363 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6365 * Added flags parameter into silc_ske_assemble_security_properties
6366 function in lib/silcske/silcske.[ch].
6368 * Changed notify client operation to fit better for notify messages
6369 sent by server. The notify payload received from server is now
6370 passed to the application (after parsing it to SilcNotifyPayload).
6371 It is application's responsibility to retrieve the arguments
6372 from the payload and show the message the way it wants. The message
6373 sent by server is implementation specific.
6375 * Changed public keys to comply with the protocol specification.
6376 Old public keys are not supported anymore and are not compatible.
6378 * Removed nickname from Channel Payload as the latest draft removed
6379 it. The client must resolve the nickname from the NAMES command
6380 reply received when it joined the channel.
6382 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6384 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6386 * Fixed some errors in protocol specification drafts.
6388 * Created lib/silccore/silcnotify.c to implement Notify Payload
6389 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6390 generic payloads described by protocol specifications. The file
6391 includes implementations for ID Payload and Argument Payload.
6393 * Changed Command Payload implementation to use the new Argument
6394 Payload. Changed command_xxxx_payload to command_payload_xxxx
6395 to comply with SILC coding conventions.
6397 * Added suppport for Argument Payload handling in Notify Payload
6398 implementation as protocol requires it. Added the new support
6399 into server and client lib as well.
6401 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Added support for multiple nicknames on same channel. [n] is
6404 added locally to the nickname if there are more than one same
6405 nicknames on the channel.
6407 * Server now sends all nicknames that matched WHOIS request.
6408 Client also shows the list received from server.
6410 * Added TOPIC command to client side. User can now set and show
6411 current topic on channel.
6413 * Added MOTD command to client and server. Also, server sends the
6414 motd when client connects to the server.
6416 * Changed version strings to comply ISO 8601.
6418 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6420 * Fixed protocol error handling in client library. It should now
6421 cope even if the SKE fails for some reason.
6423 * Made new protocol specification drafts for submitting to IETF.
6425 * Implemented TOPIC command to server in silcd/command.c.
6427 * Added two new notify types into lib/silccore/silcnotify.h:
6428 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6429 notify nickname change and topic setting/change on a channel.
6431 * API change of command_reply operation in client library. The
6432 application gets now the status type received from server as well.
6434 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6438 * Cras fixed and optimized the packet handling even further and
6439 it should work now. Minor change to the prototype of function
6440 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6442 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6444 * Added new function into lib/silcutil/silcschedule.[ch]:
6445 silc_schedule_with_fd to select() a specified fd. The function
6446 returns after timeout expires or data arrives or goes. The
6447 function is used by packet routines to wait that all data is
6448 received from network.
6450 * Fixed data reading from network in lib/silccore/silcpacket.c.
6451 The code now assures that all data is read from the fd and then
6452 continues packet processing. This was a bug fix since the code
6453 used to drop some data in some circumstances.
6455 * Added new function into lib/silcclient/client.[ch]:
6456 silc_client_start_key_exchange to start key exchange after
6457 connection has been established to server. The code internally
6458 now uses this funtion but its main purpose was to provide it
6459 for applications that perform their own connecting. After
6460 application has created a connection it merely calls this
6461 function to start the key exchange between client and server.
6462 The library takes care of everything else after that.
6464 Updated also lib/silcclient/README to explain the usage of
6467 * Do not send to application information that connection has
6468 been established. Application gets notified it by connect
6471 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6473 * Applied cras's patch to add silc_schedule_one function. The
6474 function runs scheduler once and returns.
6476 * Fixed the scheduler after cras messed it up. The timeout
6477 handling works now as it's supposed to work.
6479 * Added into lib/silccore/ silcnotify.h to include notify
6480 message types support. Changed silc_server_send_notify*
6481 functions, in server.[ch], to support those new notify types.
6482 Added the support for the notify types into client library,
6483 as well. Added new notify client operation into ops.h in
6486 * Changed silc_server_packet_send_to_channel to send normal
6487 packets instead of just channel message packets. The function
6488 is now used to send the notify packets to channels. It is not
6489 used to send channel message packets anymore, as server never
6492 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6493 va_arg()s as it seems to require it nowadays. I guess, if SILC
6494 is compiled with older va_arg() the new code should work anyway.
6496 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6498 * Splitted core library. Core library (lib/silccore) includes
6499 now only SILC protocol specific core (and common) components.
6500 Created new utility library (lib/silcutil) that includes more
6501 generic purpose stuff. The stuff for util library was taken
6502 from the old core library. This was minor and easy split.
6504 * Created SILC Client Library (lib/silcclient) that includes
6505 implementation of the SILC client without user interface. This
6506 was major move from silc/ directory. The code has been changed
6507 so that it is transparent towards the user interface. The
6508 silc/ directory includes now the same user interface as before
6509 and it uses the new client library. Read lib/silcclient/README.
6510 Basicly, the client library performs everything else related
6511 to SILC except user interface handling. Also, configuration
6512 files are considered to be part of user interface and library
6513 does not handle them.
6515 This change also changed a lot of structures, function naming etc.
6516 Most important change was that SilcClientWindow object was
6517 renamed to SilcClientConnection in the client library. Created
6518 also new file lib/silcclient/ops.h. Also added new files
6519 silc/local_command.[ch] and silc/client_ops.[ch].
6521 All these changes were made to make it easier for user interface
6522 designers to create what ever user interface for the SILC client
6525 It is also expected that the server will be moved to lib
6526 directory as well and SILC Server Library will be created;
6527 sometimes in the future.
6529 * Removed Local commands from lib/silccore/silccommand.h as
6530 they are application specific and new client library does not
6531 handle any of those anymore.
6533 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6534 old client implementation in silc/.
6536 * Added support for callback functions in SILC_LOG_* macros.
6537 Application can now set its own callbacks that will be called
6538 instead of using the default functions that will always print
6539 the debug messages to stderr (or stdout). Also, debugging can
6540 now be disabled by setting silc_debug to FALSE and re-enabled by
6541 setting it to TRUE. Note, that logging will still work even
6542 if debugging is disabled.
6544 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6545 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6546 silc_log_reset_debug_callbacks.
6548 * To enable debugging in silc client one must give now -d
6549 option on command line.
6551 * Changed silc_schedule_init to automatically allocate task queues
6552 if they are not allocated before calling it.
6554 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Added GMP 3.1 into math library.
6558 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6560 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6561 a channel in SILC network. The packet is used by servers and
6562 routers to notify other routers that user has left a channel.
6563 This little feature was missing until now. Added the feature
6564 to protocol specification as well.
6566 Added functions: silc_server_send_remove_channel_user and
6567 silc_server_remove_channel_user into server.[ch].
6569 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6570 lib/silccore/silcpacket.h. However, they are not implemented
6573 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6575 * Fixed joining to a channel and sending channel messages
6576 between server and router. The channel message sending should
6577 now work inside a cell.
6579 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6581 * Fixed the private message sending between server and router.
6582 The private message sending should now work inside a cell.
6584 * Added silc_server_replace_id into server.[ch] to replace
6585 existing ID in the SILC network.
6587 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6588 and silc_idlist_replace_server_id into idlist.[ch] in server.
6590 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6592 * Fixed the server to server connections. Server can again now
6593 connect to router. Router to router connections probably does
6596 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Added dynamic protocol registering support. Now protocols can
6599 registered and unregistered on the fly. Patch by cras.
6601 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6603 * Added lib/contrib directory to hold routines that some platforms
6604 don't have but are needed by SILC.
6606 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6607 into lin/contrib to provide getopt() and getopt_long() for
6608 those who don't have it.
6610 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Added AWAY command to client. When away message is set and
6613 client receives a private message packet the client automatically
6614 replies to the sender with the away message.
6616 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6617 bug seemed to be the cause of recent problems when compiling
6620 * Added version detection support to SKE protocol specification
6621 and added the new changes to the SKE implementation as well.
6622 There were other minor changes in the SKE protocol as well.
6624 Many changes in lib/silcske/silcske.[ch] and in
6625 lib/silcske/payload.[ch].
6627 * Added ^U functionality, clear input line. Patch from cras.
6629 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6631 * Mainly small bugfixes on core library. Fixed some debugging
6632 logging and buffer overflow in silclog.c.
6634 * Updated config.sub and config.guess on the distribution tree.
6636 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6638 * Added command lagging support in server. Client may execute
6639 commands now only once in two seconds.
6641 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6643 * Optimized packet reception. MAC computation and checking is now
6644 also more optimized. A lot previously duplicated code is now
6645 used as generic by both client and server.
6647 * Fixed key pair generation in clientutil.c
6649 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Added into lib/silccore/silcbufutil.[ch] new function;
6652 silc_buffer_realloc.
6654 * Moved generic packet sending/encryption functions to
6655 lib/silccore/silcpacket.[ch] from client and server. Some
6656 rewriting of the functions.
6658 * Moved all generic packet reception/decryption functions to
6659 lib/silccore/silcpacket.[ch] from client and server. The
6660 packet processing is now much cleaner in both client and server.
6661 These were major changes in both client and server.
6663 * Created many common functions in server to do packet sending.
6664 Previously code were duplicated a lot, this has been removed
6667 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6669 * Rewrote major parts of the ID cache system. Don't know
6670 whether it is better now or not but at least the API is more
6673 * Major rewrite on ID cache stuff on client because of the ID
6674 cache API changes. Added idlist.c to client.
6676 * Also major rewrite on ID cache stuff on server as well.
6677 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6678 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6679 in hand, instead they are all put into the ID cache system now.
6680 All server_idlist_* routines uses ID cache now instead of
6681 traversing its own lists (those lists does not exist anymore).
6682 SilcIDList though still exists. Also, SilcXXXEntry's are
6685 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6687 * Finally made the SKE implementation compliant to the protocol
6688 specification. All mp integers are now binary encoded as
6689 opposed being HEX encoded.
6691 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6694 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6695 functions: silc_[encode/decode]_pem. Also added function
6696 silc_encode_pem_file to PEM encode with newlines ('\n') for
6699 * SILC public keys are now encoded either PEM or binary. Same
6700 option is for private keys as well. By default private keys
6701 are binary encoded and public keys PEM encoded. Silly HEX
6702 encoding were removed.
6704 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6705 function to create fingerprints.
6707 * Fixed a bug in SHA1; does not change the original data anymore.
6709 * Partly implemented INFO command on client and server side.
6710 Fixed CLEAR command. Changes to SERVER command; show current
6711 server(s) when giving command without arguments. Added
6712 VERSION command to client.
6714 * Added check to server that unregistered connections cannot
6715 execute commands (unless it is specificly allowed).
6717 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6719 * Fixed screen refresh.
6721 * Fixed channel joining bug from client. On some circumstances
6722 client tried to join to a channel it had already joined.
6724 * Added public key verification process into client's protocol.c.
6725 The client now verifies the public key from user and saves
6726 it into ~./silc/serverkeys/ directory.
6728 Added into: clientutil.[ch]: silc_client_verify_server_key.
6730 * Changed SKE protocol's silc_ske_initiator_finish function
6731 to accept callback function that verifies the received public
6732 key. Removed old silc_ske_verify_public_key function.
6734 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6737 silc_pkcs_private_key[_data]_set.
6739 * Made the password and public authentication more cleaner in
6740 server's protocol.c.
6742 * Removed historic and obsolete protocol `channel_auth' from
6743 both client and server.
6745 * Removed wrong way of sending command status messages from
6746 server to client in server's command.c. The old way violated
6747 protocol specification.
6749 Changes to silccore/silccommand.[ch]: removed
6750 silc_command_encode_status_payload -> not needed anymore,
6751 changed silc_command_encode_payload_va to accept extra
6752 argument on variable argument list. The argument type must
6753 now be provided to the function. Also, added new function:
6754 silc_command_encode_reply_payload_va which is same as
6755 normal command_encode_payload_va except command status type
6756 is provided as extra argument.
6758 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6760 * Added ~./silc directory handling. The directory includes the
6761 public and private keys for the client.
6763 Added silc_client_check_silc_dir, silc_client_create_identifier
6764 and silc_client_load_keys.
6766 * Implemented SILC protocol compliant public key. Added public
6767 and private key saving to and loading from files.
6769 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6770 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6771 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6772 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6773 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6775 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6776 silc_pkcs_load_[public/private]_key.
6778 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6780 * Added silc_server_get_route (route.[ch]) to get connection
6781 data for the fastest route for given ID.
6783 * Implemented INVITE command on client and server. The command
6784 were re-defined in the SILC Protocol Specification and the
6785 implementation now complies with the specification.
6787 * Implemented PING command on client and server.
6789 * Implemented NAMES command on client and server. The server side
6790 supports currently only normal server not router server yet.
6791 Some changes to NAMES definition in SILC protocol specification.
6793 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Implemented LEAVE command on client and server.
6797 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6798 again. This change was made to the protocol as well. Server
6799 should not violate the protocol specification anymore.
6801 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6803 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6804 was tested. SOCKS4 was not but should work anyway.
