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

858 * Assure that silc_server_close_connection cannot be called
859 twice for same socket context. Affected file is
862 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
864 * Send error message to application if opening file for
865 writing during file transfer fails. Affected file is
866 lib/silcclient/client_ftp.c.
868 Remove all file transfer sessions for a client that we're
869 removing from ID cache.
871 Affected file is lib/silcclient/client_ftp.c.
873 * Fixed silc_net_addr2bin to return correct address. Affected
874 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
876 * Fixed file transfer session removing on signoff notify.
877 Affected file irssi/src/silc/core/silc-servers.c.

880 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
881 Affected file lib/silcclient/silcapi.h.
883 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
885 * Fixed a crash in silc_client_ftp_free_sessions and
886 silc_client_ftp_session_free_client. Affected file
887 lib/silcclient/client_ftp.c.
889 * Added `disabled' field in the SilcChannelEntry in the server
890 to indicate if the server entry is disabled. Affected file
891 silcd/idlist.h, silcd/command[_reply].c.
893 * SILC server adds now /var/run/silcd.pid everytime it is
894 started. Affected file silcd/silcd.c.
896 * Added silc_server_packet_send_clients to send a packet to
897 the provided table of client entries. Affected file

901 client library. Affected file lib/silcclient/client_prvmsg.c.
903 * Do not actually remove the client directly from ID cache
904 during SERVER_SIGNOFF, but invalidate it. This way we
905 preserve the WHOWAS info for the client. Affected file
908 * Fixed SERVER_SIGNOFF notify handling in the server. The
909 server is now able to process incoming SERVER_SIGNOFF notify
910 for a server that it doesn't even know about. It will remove
911 the clients provided in the notify. Affected file
912 silcd/packet_receive.c.
914 * Check for partial packet in data queue after every packet that
915 was found from the queue. Return and wait for more data if
916 there is partial data in queue. Affected file is
917 lib/silccore/silcpacket.c.
919 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

927 * Check that newsize in silc_buffer_realloc is larger than
928 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
930 * Added better monitor of file transfers. It now monitors
931 key agreement protocol during the file transfer too. Added
932 error reporting too. Affected files
933 irssi/src/silc/core/silc-servers.c,
934 irssi/src/fe-common/silc/module-formats.[ch].
936 * Wrote a help file for FILE command.
938 * Added silc_rng_global_get_byte_fast to get not-so-secure
939 random data as fast as possible. Random data is read from
940 /dev/urandom if available and from the SILC RNG if not
941 available. It is used in padding generation. Affected file
942 lib/silccrypt/silcrng.[ch].
944 * All packets in client library are now processed synchronously.
945 Optimized packet processing a lot. Affected file
946 lib/silcclient/client.c.
948 * All server connection packets are processing synchronously
949 now in server, to optimize packet processing. Affected file
952 * Include files are installed now only in Toolkit distribution
953 if make install is given. Affected files: all Makefile.am's.
955 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
957 * Assure that silc_client_notify_by_server_resolve does not
958 resolve the client information multiple times. If it cannot
959 be found by the first it cannot be found at all. Affected
960 file lib/silcclient/client_notify.c.
962 * Fixed WHOWAS command reply calling. Affected file
963 lib/silcclient/command_reply.c.
965 * Removed all references to silc_idlist_get_client from the
966 Irssi SILC client since that call is internal call used by
967 the library. The Irssi SILC client will use now client
968 retrieval functions found in silcapi.h.
970 * Fixed a bug in resolving nickname info before sending
971 private message. It used freed memory. Affected file
972 irssi/src/silc/core/silc-servers.c.
974 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
976 * Assure my_channels statistics cannot go negative in server.
977 Affected files silcd/server.c, silcd/server_util.c.

993 * Added silc_net_localip to return local host's IP address.
994 Affected file lib/silcutil/silcnet.[ch].
996 * If key exchange or rekey protocol is active for a connection
997 parse all packets syncronously since there might be packets
998 in packet queue that we are not able to process without first
999 processing packets before them. Affected file silcd/server,
1000 lib/silcclient/client.c.
1002 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1003 whether library should continue processing the packet.
1004 Affected file lib/silccore/silcpacket.h.

1039 * Resolve the client info when received private message or
1040 channel message for a client which nickname we don't know.
1041 Affected files lib/silcclient/client_prvmsg.c and
1042 lib/silcclient/client_channel.c.
1044 * Do not crash in /KEY if client is not connected. Affected
1045 file irssi/src/silc/core/silc-channels.c.
1047 * Added SilcClientStatus field to the SilcClientEntry in the
1048 lib/silcclient/idlist.h.
1050 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1051 is incomplete and is being resolved, it won't be resolved
1054 Make sure also that USERS command reply does not resolve
1055 twice information. Affected file is
1056 lib/silcclient/command_reply.c.
1058 Make sure that silc_client_get_clients_by_list does not
1059 resolve twice same information.

1073 Affected file silcd/command.c.
1075 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1077 * Call the silc_server_udpate_servers_by_server in the
1078 primary router that comes back online in the backup resuming
1079 protocol. Otherwise it routes packets wrong. Affected file
1080 silcd/server_util.[ch], silcd/server_backup.c.
1082 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1084 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1085 lib/silcutil/silcbuffmt.[ch].
1087 * Redefined the SILC packet header to include the padding
1088 length. Affected file lib/silccore/silcpacket.[ch].
1090 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1091 length for maximum padding up to 128 bytes). Affected
1092 file lib/silccore/silcpacket.h.
1094 * Removed all backwards support for old 0.5.x MAC thingies.
1095 The SILC packet header change makes it impossible to be
1096 backwards compatible.
1098 * Send the ENDING packet with timeout in the backup resuming
1099 protocol. This is to assure that all routers has connected
1100 to the primary router. Affected file silcd/server_backup.c.
1102 * Changed the RNG to take the first IV from random data. It
1103 used to take it from zero actually. Changed the RNG also
1104 to use /dev/urandom during session. /dev/random is used
1105 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1107 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1109 * Changed the SILC packet header to have the first two bytes
1110 (the packet length) encrypted. Affected files aroung the
1111 code tree, lib/silccore/silcpacket.[ch]. Removed the
1112 SilcPacketCheckDecrypt callback. It is not needed anymore
1113 since the silc_packet_receive_process will determine now
1114 whether the packet is normal or special.
1116 * Implemented the unidirectional MAC keys. Affected files
1117 lib/silcske/silcske.c, silcd/protocol.c and
1118 lib/silcclient/protocol.c.
1120 * Implemented the packet sequence number to the MAC computation.
1121 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1122 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1123 lib/silcclient/protocol.c.
1125 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1127 * Allow backup router to announce servers. All servers
1128 announced by backup router are added to the global list
1129 automatically. Update hte server's socket to our primary
1130 router also when backup router announces a server.
1131 Affected file silcd/packet_receive.c.
1133 * Do not update the client->router in the function
1134 silc_server_udpate_clients_by_server if the client is on
1135 global list. We might fail to find any specific server
1136 for locally connected clients and local cell clients. They
1137 should still use the `from' and not `to' as client->router.
1138 This fixes backup router resuming protocol. Affected file
1139 silcd/server_util.c.
1141 * Decrease channel statistics count only if the channel
1142 deletion worked. Affected files are silcd/server.c and
1143 silcd/server_util.c.
1145 * Added silc_server_update_servers_by_server to update origin
1146 of all server entries. Used during backup router protocol.
1147 Affected files silcd/server_util.[ch], silcd/server.c. and
1148 silcd/backup_router.c.
1150 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1151 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1152 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1153 lib/silccrypt/silchmac.c.
1155 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * Assure that router cannot reroute the same channel message
1158 to the sender. Affected file silcd/packet_receive.c.
1160 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * Made better checks that the channel message is not sent
1163 to the router it came from. Affected file is
1164 silcd/packet_send.c. Fixed memory leak too.
1166 * Announce informations for incoming router connection, but
1167 only after checking if it is replaced by backup router.
1168 Affected file silcd/packet_receive.c.
1170 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1172 * Fixed the backup resuming protocol to work in multiple
1173 router environment. Affected file silcd/server_backup.c.
1175 * Route packet only to one router in the function
1176 silc_server_packet_send_to_channel. Affected file is
1177 silcd/packet_send.c.
1179 * Fixed silc_server_send_notify_dest to set the broadcast
1180 flag. Fixed the silc_server_send_notify_topic to actually
1181 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1182 Affected file silcd/packet_send.c.
1184 * Changed the SFTP Filesystem interface. Changed the
1185 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1186 the filesystem operation function. The SilcSFTPFilesystem
1187 is now a context that is allocated by all filesystem allocation
1188 functions and it already includes the operations structure
1189 and filesystem specific context. It is given as argument
1190 now to the silc_sftp_server_start. This made the interface
1191 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1192 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1194 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1196 * Changed the backup router adding and getting interfaces
1197 in the server. The router that will be replaced by the
1198 specified backup router is now sent as argument. Affected
1199 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1202 * Added silc_net_addr2bin_ne to return the binary form of
1203 the IP address in network byte order. Affected files
1204 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1206 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1208 * Check for existing server ID in silc_server_new_server
1209 and in silc_server_connect_to_router_final and remove the
1210 old entry if it exists. Affected file silcd/packet_receive.c,
1213 * Send the channel message always to only one router, either
1214 in upstream or downstream. Affected file is
1215 silcd/packet_send.c.
1217 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1219 * Wrote the definition of the backup resuming protocol to the
1220 protocol specification.
1222 * Removed one redundant channel key generation from normal
1223 server during joining procedure. Removed one redundant
1224 channel key sending from server to router during joining
1225 procedure. Affected file silcd/command.c.
1227 * Made minor bugfixes to the backup router resuming protocol.
1228 Affected file silcd/server_backup.c, server.c.
1230 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1232 * Added --disable-asm configuration option. Affected files
1233 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1236 * Implemented the backup resuming protocol that is used to
1237 resume the primary router position in the cell after the
1238 primary router comes back online. Affected files
1239 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1240 and silcd/server_util.[ch].
1242 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1244 * Sleep two (2) seconds after sending QUIT command to server.
1245 Affected file lib/silcclient/command.c.
1247 * Assure that if outgoing data buffer is pending do not force
1248 send any data. Affected file silcd/packet_send.c.
1250 * Assure that if outgoing data buffer is pending do not force
1251 send any data. Affected file lib/silcclient/client.c.
1253 * Implemented the backup router support when the primary router
1254 goes down. The servers and routers can now use the backup
1255 router as new primary router without loosing connectivity.
1257 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1259 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1260 in the server to indicate disabled entry. All data read
1261 from the connection will be ignored and no data is sent
1262 for entry that is disabled. Affected files are
1263 silcd/idlist.h, silcd/server.c.
1265 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1267 * Created SFTP client and server test programs in the
1268 lib/silcsftp/tests directory.
1270 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Implemented memory filesystem (virtual filesystem) for
1273 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1276 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1278 * Implemented the SFTP (SSH File Transfer Protocol) to the
1279 lib/silcsftp. It includes SFTP client and SFTP server
1282 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1284 * Moved lib/silccore/silcprotocol.[ch] to the
1285 lib/silcutil library.
1287 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1288 take variable argument list pointer as argument. Affected
1289 file lib/silcutil/silcbuffmt.[ch].
1291 * Added silc_buffer_set function that is used to set data
1292 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1293 Affected file lib/silcutil/silcbuffer.h.
1295 * Changed various routines in the core library to use the new
1296 silc_buffer_set instead of allocating new buffer only for
1299 * Added 64-bit value formatting and unformatting support to the
1300 silc_buffer_[un]format routines. Affected file is
1301 lib/silcutil/silcbuffmt.[ch].
1303 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1304 to includes/bitmove.h.
1306 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1308 * Fixed channel user mode saving in client library. Affected
1309 file lib/silcclient/command[_reply].c.
1311 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * Defined the file transfer to the SILC Protocol. Added
1314 new packet type SILC_PACKET_FTP and defined File Transfer
1315 Payload. The mandatory file transfer protocol is SFTP
1316 (SSH File Transfer Protocol). Affected file in addition
1317 of the internet draft is lib/silccore/silcpacket.h.
1319 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1320 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1321 is used as part of backup router protocol when the primary
1322 router of the cell is back online and wishes to resume
1323 the position as primary router.
1325 * Redefined the MAC generation keys in the protocol. The
1326 same key is not used anymore in both direction. Both
1327 direction will now use different keys for sending and
1328 receiving. This fixes a potential security flaw. This
1329 change causes incompatibilities in the protocol.
1331 * Redefined also the MAC computation from the packet.
1332 An packet sequence number is now added to the MAC
1333 computation. This prevents possible replay attacks against
1334 the protocol. This change too causes incompatibilities
1337 Added `sequence' field to the SilcPacketContext to hold
1338 the current sequence number for the packet.
1340 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Added `created' field to the SilcIDListData in the file
1343 silcd/idlist.h to indicate the time when the entry was
1346 * Added `created' field to the SilcChannelEntry too. Affected
1347 file silcd/idlist.h.
1349 * Added `creation_time' aguments to all the announcement functions
1350 in the server. If it is provided then only the entries that
1351 was created after the provided time frame are actually
1352 announced. Affected file silcd/server.[ch].
1354 * The protocol says that the Channel ID's IP address must be
1355 based on the router's IP address. Added check for this in
1356 the silc_server_new_channel when processing incoming New Channel
1357 Payload. Affected file silcd/packet_receive.c.
1359 * Print out the correct version with --version in SILC client.
1360 Affected file irssi/src/silc/core/silc-core.c.
1362 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Fixed WHOWAS command to check for completnes of the client
1365 entry always, not just when the command is coming from client.
1366 Affected file silcd/command.c.
1368 * Added new function silc_server_packet_queue_purge to purge the
1369 outgoing data queue to the network. After the function returns
1370 it is guaranteed that the outgoing packet queue is empty.
1371 Affected file silcd/packet_send.[ch].
1373 * Purge the outgoing packet queue in the rekey protocol's final
1374 callback to assure that all rekey packets go to the network
1375 before quitting the protocol. Affected file silcd/server.c.
1377 * Added silc_client_packet_queue_parse as similar function as
1378 in server to the client library. The affected file is
1379 lib/silcclient/client.c.
1381 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1383 * Splitted silcd/server.c and created silcd/server_util.[ch]
1384 for utility functions.
1386 * Added new socket flag SILC_SF_DISABLED to indicate that the
1387 connection is open but nothing can be sent to or received from
1388 the connection. Affected file lib/silcutil/silsockconn.[ch].
1389 The checking for disabled socket is checked in the low level
1390 silc_socket_write and silc_socket_read functions.
1392 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1394 * Allow only nicknames and channel names that fits into the
1395 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1397 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * When processing JOIN command reply in server check that if
1400 the channel exists in our global list we'll move it the local
1401 list. Affected file silcd/command_reply.c.
1403 * Fixed the check whether client is joined on the channel already
1404 in JOIN command. Affected file lib/silcclient/command.c.
1406 * Fixed the JOIN command reply to check whether the channel
1407 already exists. Affected file lib/silcclient/command_reply.c.
1409 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Added silc_ske_status_string to map the SKE error numbers
1412 to readable strings. The affected files are
1413 lib/silcske/silcske[_status].[ch].
1415 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Do not show the private channels on the WHOIS channel list
1418 as it is not allowed by the protocol. The affected file is
1421 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1423 * Assure that the packet length digged from the actual packet
1424 is something sensible in the silc_packet_decrypt_rest_special
1425 in lib/silccrypt/silcpacket.c.
1427 * Free and NULL the allocated pointer in silc_hmac_alloc if
1428 the HMAC allocation fails. The affected file is
1429 lib/silccrypt/silchmac.c.
1431 * Print the selected security properties to the log files in
1432 the server. Affected file silcd/protocol.c.
1434 * Add SKE's reference counter even if calling the completion
1435 callback manually. Otherwise it goes negative, although it
1436 does not cause any problems. The affected file is
1437 lib/silcske/silcske.c.
1439 * Remove the client entry with short timeout after giving the
1440 KILL command. Affected file lib/silcclient/command.c.
1442 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1443 case all found clients are already disconnected (WHOWAS would
1444 found them) in the server. Affected file silcd/command.c.
1446 * Update the last_receive (time of last data received) to be
1447 updated only when received private or channel message so that
1448 the idle time showed in WHOIS makes more sense.
1450 * Added boolean field `valid' in to the SilcClientEntry in the
1451 client library to indicate whether the entry is valid or not.
1452 This fixes the nickname change bug on channel when changing
1453 the nickname to be same than the old (like nick to Nick) the
1454 nickname formatter doesn't set the new nick anymore to Nick@host.
1455 Affected file lib/silcclient/idlist.[ch].
1457 * Now actually fixed the nickname changing on disconnection.
1458 Added new function silc_change_nick to the Irssi SILC Client.
1459 Affected file irssi/src/silc/core/client_ops.c,
1460 irssi/src/silc/core/silc-nicklist.[ch].
1462 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * Check that the public key exists in the GETKEY command before
1465 trying to encode it. Affected file silcd/command.c.
1467 * Print some notifications on received public keys with GETKEY
1468 command in the Irssi SILC Client. Affected files are
1469 irssi/src/fe-common/silc/module-formats.[ch],
1470 irssi/src/silc/core/client_ops.c.
1472 * Use IDENTIFY command to resolve the server information in the
1473 GETKEY command instead of INFO command. Affected file
1474 lib/silcclient/command.c.
1476 * All command reply functions in the client library now calls
1477 the pending command reply callbacks even if an error has
1478 occurred. The server has done this a long time and now it was
1479 time to move the client library to this as well. Now all
1480 errors can be delivered back to the pending command reply
1481 callbacks if necessary. Affected files are
1482 lib/silcclient/command[_reply].[ch].
1484 * Change the nickname on disconnection back to the username
1485 because in reconnect the server will enforce it to it anyway.
1486 Affected file irssi/src/silc/core/silc-servers.c.
1488 * Fixed a config file parsing bug in the Irssi SILC client.
1489 Affected file irssi/src/silc/core/clientconfig.c.
1491 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * When printing the channel mode on JOIN, verify that the
1494 channel key and channel's HMAC are valid. Affected file
1495 irssi/src/silc/core/client_ops.c.
1497 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1499 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1500 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1501 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1503 * Removed channel key rekey task deleting from the function
1504 silc_server_save_channel_key. Affected file silcd/server.c.
1505 Added explicit timeout task context instead that is used to
1506 delete the task if we are registering a new task before the
1507 new task has elapsed.
1509 * When channel key rekey occurs the client library now saves
1510 the old channel key for a short period of time (10 seconds) and
1511 is able to use it in case some is still sending channel
1512 messages encrypted with the old key after the rekey. Affected
1513 file lib/silcclient/[idlist.h|client_channel.c].
1515 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1517 * Added check to the silc_server_new_id_real to not accept
1518 new ID if it is the sender's own ID. Affected file is
1519 silcd/packet_receive.c.
1521 * Assure that we do not announce ourself or the one we've
1522 sending our announcements when we're router and are announcing
1523 servers to our primary router. Affected file silcd/server.c.
1525 * Fixed silc_server_command_identify_check_client to assemble
1526 correct WHOIS packet. It send corrupted WHOIS packet and
1527 caused problem with router to router connections. Affected
1528 file silcd/command.c.
1530 Fixed also silc_server_command_whois_check the same way
1531 as for the IDENTIFY command.
1533 * Added new SilcIDListStatus to the server in the SilcIDListData
1534 structure. The status now includes the current status of
1535 the entry (like registered, resolved etc.). Affected file
1536 silcd/idlist.[ch]. Defined a bunch of different status types
1537 as well. This replaced the old boolean registered field as well.
1539 Added resolve_cmd_ident field to the SilcClientEntry structure
1540 too so that if the entry is for example being resolved so
1541 another command may attach to the same pending command reply
1542 without requiring to resolve the same entry again. This concept
1543 should optimize the WHOIS and the IDENTIFY resolving under
1544 heavy load by taking away unnecessary resolving for entries
1545 that are being resolved already.
1547 Added support for adding multiple pending commands for one
1548 command idenfier. Affected file silcd/command[_reply].[ch].
1550 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1551 before deleting the data. Otherwise the hash table will have
1552 freed data in comparison functions. Affected file is
1553 silcd/command_reply.c.
1555 * Fixed silc_idlist_replace_client_id to add the new entry to
1556 the cache with NULL nickname. Otherwise there will be invalid
1557 memory as the nickname after the nickname is freed. Affected
1558 file silcd/packet_receive.c.
1560 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1561 saved into wrong slots because the previous number of entries
1562 was not taken into account. Affected file silcd/idlist.c.
1563 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1565 * If we are router and we receive JOIN notify to a channel that
1566 does not have any users then notified client is marked as the
1567 channel founder, as it is it. The affected file is
1568 silcd/packet_receive.c
1570 * Added to the extended hash table API's table_del_*ext functions
1571 the destructor as argument too, so that the caller can decide
1572 which destructor to use or whether to use destructor at all.
1573 Affected file lib/silcutil/silchashtable.[ch].
1575 * Fixed ID Cache purging. It actually deleted the entries from
1576 the hash table after the data was freed. The hash table ended
1577 up comparing freed memory. The affected file is
1578 lib/silccore/silcidcache.c.
1580 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1582 * Fixed Irssi SILC client's KILL command's HELP syntax.
1584 * The USERS command now resolves the detailed user information
1585 if the userinfo field is missing. Affected file is
1586 lib/silcclient/command_reply.c.
1588 * Do not print error in silc_file_read if the read file does
1589 not exist. Just silently return NULL. Affected file is
1590 lib/silcutil/silcutil.c.
1592 * Fixed the silc_log_output to not wine about NULL filename
1593 and to not create some bogus " " filename. Affected file is
1594 lib/silcutil/silclog.c.
1596 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Fixed various printing bugs on the user interface in the
1599 Irssi SILC Client. Minor changes that were forgotten from
1602 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1604 * Fixed the configure.in.pre and the compilation and distribution
1605 environment to support the new autoconf 2.52. That version is
1606 now required to compile the CVS trunk.
1608 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1610 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1611 to generally parse user@fqdn format strings. Affected file
1612 lib/silcutil/silcutil.c.
1614 * Added nickname_format and nickname_force_format fields to the
1615 SilcClientParams structure. The first one defines the format
1616 for the nicknames that the library will enforce if the receives
1617 multiple same nicknames. The second one is boolean value and
1618 can be used to force the library to always enforce the format
1619 to the nicknames regardles whether there are multiple nicknames
1620 or not. This configurable formatting was employed to flexibly
1621 support accessing multiple nicknames from the user interface.
1622 The userinterface can now set the nicknames to what ever format
1623 they prefer. Affected file lib/silcclient/silcapi.h.
1625 Added function silc_client_nickname_format to the file
1626 lib/silcclient/idlist.c. It performs the nickname formatting.
1628 Added new field `hostname´ to the SilcClientEntry context.
1629 It holds the hostname of the client. Affected file is
1630 lib/silcclient/idlist.h.
1632 * Irssi SILC Client sets the nicknames in nick@hostn format.
1633 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1634 irssi/src/silc/core/silc-core.c.
1636 The WHOIS printing now also shows both the real nickname and
1637 the formatted nickname so that user knows how to access the
1638 user if there are multiple same nicknames cached. Affected
1639 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1640 printing formatting too to take the hostname now as a separate
1641 argument. The Affected file is
1642 irssi/src/fe-common/silc/modules-formats.[ch].
1644 * Changed the silc_client_get_clients_local to accept the formatted
1645 nickname as argument. It accepts the real nickname too but the
1646 formatted nickname can be used to find the true entry from
1647 multiple entries. Affected file lib/silcclient/silcapi.h and
1648 lib/silcclient/idlist.c.
1650 * Added nickname_format_parse field to the SilcClientParams.
1651 It is a callback function provided by the application to parse
1652 the nickname out of the formatted nickname string. The library
1653 calls it to get the nickname from the formatted string. Since
1654 the application generally knows better the format of the nickname
1655 string it parses it instead of the library, even though library
1656 encodes the formatted string. If the callback function is not
1657 provided then the library will use the string as is. The
1658 affected file is lib/silcclient/silcapi.h.
1660 * All the nickname strings passed to the client library in
1661 commands are now expected to be formatted nickname strings.
1662 If the command does not support the formatted nickname string
1663 it will assume that the sent string is the actual nickname.
1664 Affected file lib/silcclient/command.c.
1666 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Added public key authentication support to OPER and SILCOPER
1669 commands in the client library. Affected file is
1670 lib/silcclient/command.c.
1672 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1674 * Changed the get_auth_methdod client operation to be asynchronous.
1675 It can be async if the application resolves the authentication
1676 method from the server during the negotiation. Added new
1677 SilcGetAuthMeth completion callback that the application will
1678 call after resolving the authentication method.
1680 Added function silc_client_request_authentication_method that
1681 the application can use to resolve the authentication method
1682 from the server. Added also SilcConnectionAuthRequest callback
1683 that the library will call after the server has replied. The
1684 application can call this function if it does not know the
1685 current authentication method.
1687 Affected files are lib/silcclient/client.c and
1688 lib/silcclient/silcapi.h.
1690 * The Irssi SILC client now automatically resolves the authentication
1691 method incase any configuration information is not present (and
1692 currently there never is). The affected file is
1693 irssi/src/silc/core/client_ops.c.
1695 * Fixed public key authentication from the client library.
1696 Affected file lib/silcclient/protocol.c. Changed also the
1697 protocol specification about the public key authentication in
1698 the connection authentication protocol. The actual data to be
1699 signed is now computed with a hash function before signing.
1701 * Fixed the public key authentication from the server as well.
1702 Affected file silcd/protocol.c.
1704 * Removed the mlock()'s from the memory allocation routines.
1705 Affected file lib/silcutil/silcmemory.c. The ./configure does
1706 not check anymore for the mlock(). Affected file is
1709 * Fixed USERS command in server to allow the execution of the
1710 command for private and secret channels if the client sending
1711 the command is on the channel. Affected file silcd/command.c.
1713 * Fixed silc_client_get_clients_local to return the clients
1714 count correctly. It could return wrong value. Affected file
1715 lib/silcclient/idlist.c.
1717 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1719 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1720 types. The assembler optimizations seemed not to like 64-bit
1721 data types. The assmebler optimizations thus are now enabled
1722 also for BSD systems as opposed to only enable them for Linux.
1724 * Do not check for threads at all on BSD systems. Affected
1725 file configure.in.pre.
1727 * Removed -n and -h options from the Irssi SILC Client since
1728 they are not used in silc.
1730 * Fixed the prime generation to assure that the first digit
1731 of the generated random number is not zero since our conversion
1732 routines does not like number strings that starts with zero
1733 digit. If zero digit is seen the random number is regenerated.
1734 This caused some corrupted RSA keys when the zero first digit
1735 was met. Affected file lib/silcmath/silcprimegen.c.
1737 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * Fixed WIN32 configuration in the ./configure script.
1740 Fixed to include xti.h on environments that has it.
1741 Patches by Carsten Ilchmann and andrew.
1743 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1745 * Changed the silc_id_create_client_id to be collision
1746 resistant. It is now assured that there cannot be created
1747 two same client ID's. I suspect that some weird bugs in
1748 the server were actually caused by duplicate Client IDs.
1749 Affected file silcd/serverid.[ch]. A router receiving
1750 new ID now also assures and informs the sending server
1751 if the ID caused collision.
1753 * Changed the silc_id_create_channel_id to also assure that
1754 there are no collisions.
1756 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1758 * Statement about ignoring the Mutual Authentication flag when
1759 performing rekey with PFS was a bit misleading. It is ignored
1760 if it was set in the initial negotiation, it cannot be even
1761 set in the rekey. Fixed in the ke-auth draft. Started the
1762 new versions of the protocol drafts in the doc/.
1764 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1766 * Fixed a bug in silc_client_command_identify_save when saving
1767 new channel information. The channel name was no duplicated
1768 and caused crash on exit. Affected file is
1769 lib/silcclient/command_reply.c.
1771 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1773 * Fixed the getkey command handling in the server. Send just
1774 empty OK reply to the sender if the key could not be fetched
1775 (but everything else was ok, like the key just was not available).
1776 Changed the public key parameter to optional in the protocol
1777 specs so that empty OK reply can be sent. Affected file
1780 Added a message to Irssi SILC client to tell to user if the
1781 server did not return a public key.
1783 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1785 * Fixed a channel key regeneration bug. It registered new
1786 timeout tasks exponentially until all system resources were
1787 used. Affected file silcd/server.c.
1789 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1791 * Added the SILC Document generator to the scripts/silcdoc.
1792 It can be used to generate the Toolkit Reference Manual out
1793 of the source tree. Internally it will also use the RoboDoc
1794 generator now imported in util/robodoc.
1796 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Added couple of return's in rekey protocol if error orccurred
1799 during the protocol. The execution must be terminated.
1800 Affected file silcd/protocol.c. Also, terminate the protocol
1801 always with timeout.
1803 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * The client's Client ID was created initally from the wrong
1806 nickname (it could have been in format nick@host) in the
1807 silc_server_new_client. Affected file silcd/packet_receive.c
1809 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1811 * Added some SILC_LOG_ERROR's to various error conditions
1812 if client could not be added to ID cache. Affected files
1813 silcd/packet_receive.c and silcd/server.c.
1815 * When client's sock->user_data is freed, NULL also the
1816 client->router and client->connection pointers. Added check
1817 for these pointers being NULL to various places around the
1818 code. Affected file silcd/server.c.
1820 * Added client->data.registered == TRUE checks to various
1821 places around the code to assure that unregistered client's
1822 are not handled when it is not allowed. Affected file
1825 * Added `bool registered' fields to all
1826 silc_idlist_[server|client]_get_* routines to indicate whether
1827 the fetched client needs to be registered or not. Affected
1828 file silcd/idlist.[ch].
1830 * Add your own entry as registered to the ID cache in the
1831 server. Affected file server.c.
1833 * Fixed a bug in silc_server_new_server. The SilcServer was
1834 set as the new server's context instead of SilcServerEntry.
1835 This naturally caused some weird bugs.
1837 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * Do not delete the channel rekey task when adding it
1840 for in silc_server_create_channel_key.
1842 * Changed the silc_server_create_channel_key to return
1843 TRUE or FALSE to indicate the success of the channel key
1846 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1848 * Fixed MSVC++ project files and added missing files to
1849 Makefiles under win32/.
1851 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Do not add TCP_NODELAY flag if the operating system
1854 does not have it defined. Affected files are
1855 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1857 * Fixed buffer overflow from Irssi SILC Client. Affected
1858 file irssi/src/fe-common/core/themes.c.
1860 * Fixed double free in client library in the file
1861 lib/silcclient/client.c when disconnecting from server.
1863 * Applied double free patch from cras to Irssi SILC client.
1864 Affected files irssi/src/core/[modules/expandos].c
1866 * Fixed the disconnection handling to Irssi SILC Client.
1867 The application must call silc_client_close_connection
1868 in ops->connect client operation in case of failure of
1869 the connection. Affected file is
1870 irssi/src/silc/core/client_ops.c.
1872 * Do not set sock->protocol to NULL in the function
1873 silc_client_close_connection after executing the protocol's
1874 final callback since the sock might not be valid anymore.
1875 Affected file lib/silcclient/client.c.
1877 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1879 * Do not enable SILC_THREADS if the linking with libpthread
1880 did not happen. Affected file configure.in.pre.
1882 * Added notion to protocol specification that server must
1883 verify the sent authentication payload with CMODE when
1884 setting the channel founder key. Implemented it to the
1885 server. Affected file silcd/command.c.
1887 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1889 * Added _EXTRA_DIST SILC distribution variable to the
1890 distributions file. It is used to conditionally add extra
1891 files or directories to the specific distribution. Affected
1892 files ./prepare, Makefile.am.pre and distributions.
1894 Removed the `_' from the start of the distribution names.
1897 * Added README.WIN32 for instructions to compile the Toolkit
1900 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1902 * Fixed a double free in disconnection in the server. Affected
1903 file is silcd/server.c.
1905 * Fixed the lib/silcske/groups.c to work now also with GMP
1906 MP library. The string conversion did not work when using
1907 specific base and the base is indicated in the string as well.
1909 * Created win32/ directory which now includes MSVC++ specific
1910 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1911 It will appear only in the toolkit distribution
1913 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1915 * Changed the key material distribution function in case when
1916 the hash output is too short. The data is now concatenated
1917 a bit differently than it used to. Made the change to the
1918 SKE protocol specification.
1920 * Added better GMP detection to configure.in.pre. A patch
1923 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Fixed a minor bug in SKE that might cause some problem on
1926 some platforms. Affected file lib/silcske/silcske.c.
1928 * Added the cookie checking for initiator in the SKE. It checks
1929 that the responder returns the sent cookie unmodified. The
1930 affected file is lib/silcske/silcske.c. Added new SKE
1931 error type INVALID_COOKIE that can be sent during the
1932 negotiation. Fixed some memory leaks as well.
1934 * Added the "invalid cookie" error message to Irssi SILC client's
1937 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * Added `task_max' field to the SilcClientParams to indicate
1940 the maximum tasks the scheduler can handle. If set to zero,
1941 default values are used. Affected file lib/silcclient/silcapi.h.
1943 * Fixed memory leaks in silc_client_close_connection. Affected
1944 file lib/silcclient/client.c.
1946 * Added silc_client_del_client_entry to client library to free
1947 all memory of given client entry. Affected file is
1948 lib/silcclient/idlist.[ch].
1950 * Added new functions silc_client_del_channel and
1951 silc_client_del_server to delete channel and server entries.
1952 Affected file lib/silcclient/[silcapi.h/idlist.c].
1954 * Removed silc_client_del_client_by_id from silcapi.h.
1956 * Fixed the INFO command to return the server's own info
1957 correctly when querying by Server ID. Affected file is
1960 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * Removed the non-blocking settings in WIN32 code in the
1963 silc_sock_[read/write] and added SleepEx instead. Affected
1964 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1965 of input data is now checked with FIONREAD and ioctlsocket.
1967 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Call silc_schedule_task_del_by_context in the
1970 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1971 Affected file lib/silccore/silcprotocol.c.
1973 * Call silc_protocol_cancel for active protocols in the
1974 silc_server_close_connection if the funtion
1975 silc_server_free_sock_user_data has not been called.
1976 Affected file silcd/server.c.
1978 * Generic tasks cannot be deleted using the del_by_fd
1979 task deleting function since generic tasks does not match
1980 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1982 * Added a notion to SILCOPER help file that the SILCOPER works
1983 only on router server, not on normal server.
1985 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1987 * Added for WIN32 support for the new scheduler as well.
1988 Affected file lib/silcutil/win32/silcwin32schedule.c.
1990 * Fixed the SHA1 implementation to work on various platforms.
1992 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1994 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1995 API. It is part of the scheduler now. Everything else is
1996 as previously but some functions has changed their names.
1997 Checkout the lib/silcutil/silcschedule.h for the interface.
1998 Updated all applications to use the new interface. Affected
1999 files are lib/silcutil/silcschedule.[ch].
2001 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * Found a bug in the SKE implementation. The HASH value,
2004 specified by the protocol, was not computed correctly. The
2005 public key of the responder was not added to the computation
2006 even though it is mandatory. Affected file lib/silcske/silcske.c.
2007 This unfortunately causes incompatibilities with older
2008 clients and servers.
2010 * Added WIN32 specific network init and uninit functions:
2011 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2012 the Winsock2. Affected file lib/silcutil/silcnet.h and
2013 lib/silcutil/win32/silcwin32net.c.
2015 * Set the socket always to nonblocking mode on WIN32 after
2016 reading data or writing data. Affected file is
2017 lib/silcutil/win32/silcwin32sockconn.c.
2019 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2021 * Fixed various compilation problems under WIN32. Affected
2022 files lib/silcutil/win32/silcwin32thread.c and
2023 lib/silcutil/win32/silcwin32schedule.c.
2025 * Removed all _internal.h #includes from public header
2026 files. Internal headers must never be included from
2029 Removed also the lib/silcske/payload_internal.h file.
2031 * All include files that may be needed (public and some others
2032 included by the public headers) by application developers are
2033 now copied to the ./includes directory. It does not copy any
2034 internal headers. Affected file Makefile.defines.pre and all
2035 Makefile.am's under lib/ and subdirs.
2037 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2039 * Do not change the ~/.silc directory's permissions automatically.
2040 Affected file irssi/src/silc/core/clientutil.c.
2042 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2044 * Do not cancel the protocol in silc_server_close_connection
2045 it might cause recursion. Now cancelled in the function
2046 silc_server_free_sock_user_data. Affected file silcd/server.c.
2048 * Fixed the silc_server_remove_clients_by_server to regenerate
2049 the channel keys correctly finally. Added also new function
2050 silc_server_remove_clients_channels to actually do it.
2051 Affected file silcd/server.c.
2053 * Fixed the silc_server_new_channel to not crash by giving
2054 wrong router to the new channel. Affected file is
2055 silcd/packet_receive.c.
2057 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2059 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2060 which is given as argument to the silc_client_alloc now.
2061 It can be used to configure the client and set various parameters
2062 that affect the function of the client.
2064 * The USERS command in server did not check whether the channel
2065 is private or secret. Affected file silcd/command.c.
2067 * Added new argument to the USERS command in protocol specification.
2068 The USERS command now can take the channel name as argument
2069 as well. Added support for this in client and server and
2070 updated the protocol specs.
2072 * Completed the GETKEY command in client. It can be now used
2073 to fetch also servers public key not only some clients.
2074 Affected files lib/silcclient/command[_reply].c.
2076 * Added silc_client_get_server to return server entry by the
2077 server name. Affected files lib/silcclient/silcapi.h and
2080 * Redefined the IDENTIFY command in protocol specification to be
2081 more generic. It now can be used to query information about
2082 any entity in the SILC Network, including clients, servers and
2083 channels. The query may be based either the entity's name
2084 or the ID. Added support for this in both client and server.
2086 Affected files silcd/command.c and lib/silcclient/command.c
2087 and command_reply.c.
2089 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2090 the _from_client and _from_server functions. Affected file
2093 * Added silc_client_get_channel_by_id_resolve to the file
2094 lib/silcclient/silcapi.h to resolve channel information by
2095 its ID. Added also silc_client_get_channel_by_id that
2096 does not resolve it from the server.
2098 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2100 * Added SilcServerEntry context into the client library
2101 to represent one server. The INFO command now allocates
2102 these to save the resolved server info. For now on the
2103 client library will also keep information about servers,
2104 connected and resolved with INFO.
2106 The INFO command now allocates the SilcServerEntry context
2107 and saves the server info there. The COMMAND_REPLY in
2108 the INFO now returns the parameters to application in
2109 same order as defined in the protocol specification.
2111 The entries are cached in the client->server_cache.
2113 * The INFO command is now issued after received the Client ID
2114 from the server. Affected file lib/silcclient/client.c.
2116 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2117 to the application as the mode changer might be server.
2118 It is guaranteed that NULL is not returned anymore to the
2119 application. Affected file lib/silcclient/client_notify.c.
2121 The ID Type is now also passed to the application so that
2122 it can check whether the returned entry is SilcClientEntry
2125 Added new function silc_client_get_server_by_id to return
2126 the server entry by ID. Affected files are the
2127 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2129 * Do not create the channel in the Irssi SILC Client when issuing
2130 the JOIN command but when received the sucessful JOIN command
2131 reply. Otherwise the channel might get created even though we
2132 could not join it. The Affected file is
2133 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2135 * Fixed a channel joining bug in router. The router must also
2136 check the channel modes, invite and ban lists etc. when serving
2137 the JOIN command sent by normal server. Affected file is
2138 silcd/command.c. The router now resolves the client's
2139 information from the server who sent the JOIN command if it
2140 does not know it, and processes the JOIN command only after
2143 * Changed the SilcCommandCb to take new argument; void *context2.
2144 Affected file lib/silccore/silccommand.h
2146 The second argument in the command callbacks in the server now
2147 includes the SilcServerCommandReplyContext if the command was
2148 called as pending command callback from the command reply.
2149 Otherwise it is NULL. When called as pending the status of the
2150 command reply will be checked and if it was erronous the
2151 error will be sent to the original sender of the command.
2152 This way the client always receives the error messages even
2153 though the server was actually the one who received the error
2154 when it resent the command to router, for example. Affected
2155 files silcd/command[_reply].[ch].
2157 * Fixed sending WHOWAS command's error message to client if
2158 the requested client could not be found. It was missing.
2161 * Changed the CMODE and CUMODE commands reply arguments in the
2162 protocol specification. The Channel ID is now sent in both
2163 of the commands to identify the channel. Implemented this
2164 new feature to the client and server. Affected files
2165 lib/silcclient/command_reply.c and silcd/command.c.
2167 * Made better checks for invite and ban lists in the JOIN
2168 command in server. Affected file silcd/command.c.
2170 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2172 * The server now performs the incoming host IP/DNS lookup
2173 using the silc_socket_host_lookup and thus does not block
2174 the server anymore. Affected file silcd/server.c.
2176 * Completed the multi-thread support for SILC Scheduler in
2177 the lib/silcutil/silcschedule.c.
2179 * Fixed the configure.in.pre to detect the pthread correctly
2182 * Fixed a deadlock in silc_task_queue_wakeup in the file
2183 lib/silcutil/silctask.c.
2185 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2187 * Added new function silc_schedule_wakeup that is used in
2188 multi-threaded environment to wakeup the main thread's
2189 schduler. It needs to be used when a thread adds a new task
2190 or removes a task from task queues. After waking up, the
2191 scheduler will detect the task queue changes. If threads
2192 support is not compiled in this function has no effect.
2193 Implemented the wakeup mechanism to both Unix and WIN32
2194 systems. Affected files are lib/silcutil/silcschedule.[ch],
2195 lib/silcutil/unix/silcunixschedule.c and the
2196 lib/silcutil/win32/silcwin32schedule.c.
2198 * Added new function silc_task_queue_wakeup to wakeup the
2199 scheduler by the specified task queue. Affected file
2200 lib/silcutil/silctask.[ch].
2202 * The silc_socket_host_lookup_start now wakes up the scheduler
2203 after adding the timeout task. Affected file is
2204 lib/silcutil/silcsockconn.c.
2206 * The silc_socket_host_lookup is synchronous now if the threads
2207 support is not compiled in. However, the callback is still
2208 called asyncronously through the scheduler, anyway. Affected
2209 file lib/silcutil/silcsockconn.c.
2211 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2213 * Added new function silc_socket_host_lookup to perform
2214 asynchronous IP and FQDN lookups for the socket connection.
2215 Affected files lib/silcutil/silcsockconn.[ch].
2217 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2219 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2220 that may or may not compile the mutex support in.
2222 Changed the silc_mutex_alloc interface. It allocates the
2223 mutex now to the sent pointer and returns TRUE or FALSE.
2225 Affected file lib/silcutil/silcmutex.h.
2227 * Wrote the SILC Task Queue interface to support multi-threads.
2228 Affected file lib/silcutil/silctask.[ch].
2230 * Wrote the SILC Scheduler to support multi-threads. Affected
2231 file lib/silcutil/silcschedule.c.
2233 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2235 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2236 in lib/silcutil/win32/.
2238 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Defined SILC Mutex API and SILC Thread API and implemented
2241 them for Unix. Affected files are
2242 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2243 lib/silcutil/unix/silcunixmutex.c and
2244 lib/silcutil/unix/silcunixthread.c.
2246 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Fixed the silc_server_remove_clients_by_server's channel
2249 key re-generation. The hash table handling was incorrect
2250 and would not work with many channels. Affected file is
2253 * Fixed some memory leaks around the server code.
2255 * Rewrote the silc_server_get_users_on_channel to support IPv6
2256 based Client ID's. Affected file silcd/server.c.
2258 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2259 specification. However, a separate document must be written
2260 to define the detailed signing procedure and the payload
2261 associated with the flag. Defined the flag to the
2262 lib/silccore/silcchannel.h as well.
2264 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2266 * Changed the dynamic tables to static size tables in the
2267 lib/silccrypt/silchmac.c.
2269 * Removed GCC dependencies from the code. A patch by cras.
2271 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Do not show the error "Error receiving packet bla bla"
2274 in server if it really was not an error (-2 means that reading
2275 is pending). Affected file silcd/server.c.
2277 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2279 * Fixed a possible crash in silc_server_remove_clients_by_server
2280 in silcd/server.c. Fixed there also some memory leaks.
2282 * Fixed the silc_idlist_replace_client_id. It could replace
2283 wrong key in the hash table. Affected file silcd/idlist.c.
2285 * Do not check whether there are global users on the channel
2286 if the channel->global_users is FALSE. Affected functions
2287 silc_server_remove_from_one_channel and
2288 silc_server_remove_from_channels in silcd/server.c. Also,
2289 do not check if the removed client is local as we can be
2290 sure that global client was not removed from the channel
2291 and checking for global users is not needed.
2293 * The silc_server_remove_clients_by_server now re-generates
2294 the channel keys correctly for those channels that had
2295 clients removed from them. Affected file silcd/server.c.
2297 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2299 * Found the reason of random crashes in the server. We weren't
2300 ignoring the SIGPIPE signal (which can be sent in write())
2301 and it crashed the server. Affected file silcd/silcd.c.
2303 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2305 * Assure that sock->user_data is not NULL in the function
2306 silc_server_packet_send in silcd/packet_send.c.
2308 * Disconnect the remote connection if it could not be added
2309 to any ID lists in the server. The affected file is
2312 * Check in silc_server_packet_send[_real/dest] that the
2313 socket is not disconnecting and ignore the data if it is.
2314 Affected file silcd/packet_send.c.
2316 * Define inline to __inline on native WIN32 compilation.
2317 Affected file includes/silcwin32.h.
2319 * Added some explicit type casts for inline code since MSVC
2320 require them. Affected files lib/silcutil/silcbuffer.h,
2321 lib/trq/silcdlist.h and lib/trq/silclist.h.
2323 * Print warning in log files from now on if the packet
2324 decryption fails. Affected file silcd/server.c.
2326 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2328 * Changed the `say' client operation's interface to accept
2329 new `type' argument to indicate the type of the message sent
2330 by the library. The application may filter the library's
2331 messages according the type. The affected file is the
2332 lib/silcclient/silcapi.h.
2334 * Added two new functions to lib/silcclient/silcapi.h:
2335 silc_client_del_client and silc_client_del_client_by_id.
2336 Affected file lib/silcclient/idlist.c.
2338 * Moved the clientincludes.h from includes/ to silc/ and
2339 serverincludes.h from includes/ to silcd/.
2341 * The modes for the CMODE and CUMODE are now passed as
2342 uint32 for application with COMMAND_REPLY. The affected
2343 file is lib/silcclient/command_reply.c.
2345 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2347 * /WHOIS without arguments shows client's own information.
2348 Affected file lib/silcclient/command.c.
2350 * Changed PING to not accept any arguments. The specs
2351 says that client can ping only the connected server so
2352 requiring an argument is not needed. Affected file is
2353 lib/silcclient/command.c.
2355 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2357 * Fixed a fatal bug in private message sending and reception
2358 encryption and decryption when using private message keys.
2359 The implementation was incorrect and did not follow the
2360 specification. It causd that some of the message were
2361 lost since it did not use the sending and receiving keys
2362 as the protocol suggests. This has been fixed and will cause
2363 incompatibilities with older clients when sending private
2364 message encrypted with private message keys. Affected files
2365 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2366 and various other in Irssi SILC Client.
2368 Added `responder' boolean argument to the functions
2369 silc_client_add_private_message_key[_ske] to indicate when
2370 the key is added as responder or initiator of the key
2373 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Removed the silc_ske_check_version function and created
2376 a SilcSKECheckVersion callback. Added also a function
2377 silc_ske_set_callbacks that is now used to set all SKE
2378 callbacks. The callback functions are not given to
2379 the SKE functions anymore, but this function is used to
2382 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2384 * Added `silc_version' argument to the silc_client_alloc
2385 to define the version of the application for the library.
2386 The library will use the version string to compare it
2387 against the remote host's (usually a server) version
2388 string. Affected file lib/silcclient/silcapi.h
2390 * Added the KE protocol context to Key Agreement context
2391 in client library so that we can abort the SKE if it
2392 is in process when we get timeout. Affected file is
2393 lib/silcclient/client_keyagr.c.
2395 * Do not resolve the client ID forever if it returns in the
2396 first time that such client does not exist. This was done
2397 for example with private message. Affected file is
2398 lib/silcclient/client_prvmsg.c.
2400 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Do not add regex.h for WIN32. The affected file
2403 includes/silcincludes.h.
2405 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2406 not work yet 100%. It generates the DLL's automatically
2407 when compiling with --with-win32 under cygwin.
2409 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * lib/contrib/regex.c is not compiled on WIN32.
2413 * Added silc_net_get_socket_opt function to the
2414 lib/silcutil/silcnet.h.
2416 * Added includes/silcwin32.h for WIN32 specific includes
2419 * Do not use ptime structure or any of the posix process
2420 functions on WIN32 in lib/silccrypt/silrng.c.
2422 * Added silc_gettimeofday to provide generic function
2423 for struct timeval on all platforms. Added the function
2424 to lib/silcutil/silcutil.h.
2426 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2428 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2429 library as they clearly belong there. As a plus side we
2430 can make the actual socket connection routines platform
2433 Added also new generic function silc_socket_read and
2434 silc_socket_write (that used to be silc_packet_[read/write].
2435 The implementation of these are platform specific.
2437 * Added WIN32 specific routines of silc_socket_[read/write]
2438 to lib/silcutil/win32/silcwin32sockconn.c.
2440 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2442 * Added preliminary support for native WIN32 compilation under
2443 cygwin (using the -mno-cygwin option for GCC) to the
2444 ./configure.in.pre. The --with-win32 now prepares the
2445 compilation for native WIN32.
2447 * Rewrote the SILC Scheduler interface in the file
2448 lib/silcutil/silcschedule.h. The scheduler is now context
2449 based and does not have anymore any global static scheduler.
2450 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2451 and created lib/silcutil/win32 directory for WIN32 based
2454 * Added Unix specific network routines to the
2455 lib/silcutil/unix/silcunixnet.c and the old
2456 lib/silcutil/silcnet.c includes now only generic routines.
2458 Added WIN32 specific network routines to the
2459 lib/silcutil/win32/silcwin32net.c.
2461 * Added Unix specific utility functions from the
2462 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2464 * Added WIN32 SILC Scheduler to the file
2465 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2468 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Do not handle JOIN notify in the server if the target client
2471 is not registered (idata->registered == FALSE). The affected
2472 file is silcd/packet_receive.c.
2474 * Update the nickrec->founder in event_cumode in the Irssi SILC
2475 client. Affected file irssi/src/silc/core/silc-channels.c.
2477 * Fixed the CUMODE_CHANGE notify handling in the server when
2478 server and router are announcing their clients on channels.
2479 Now the mode changes are saved and notified correctly. The
2480 affected file is /silcd/packet_receive.c.
2482 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2483 They really did not replace the cache entry in the ID Cache.
2484 Now they do that. Affected file silcd/idlist.c.
2486 * Fixed the KICK notify handling in the Irssi SILC client to
2487 update the channel records so that the kicked client does not
2488 appear to be on the channel. The affected file is
2489 irssi/src/silc/core/silc-channels.c.
2491 * Always update the conn->current_channel when executing command
2492 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2494 * Fixed the KILL notify handling in Irssi SILC client to remove
2495 the killed client on all channels.
2497 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2499 * Fixed the silc_parse_command_line to remove extra spaces
2500 from the start and end of the arguments. Affected file is
2501 lib/silcutil/silcutil.c.
2503 * Cancel and free any active protocol in the function
2504 silc_server_close_connection. Affected file silcd/server.c.
2506 * Cancel and free any active protocol in the function
2507 silc_client_close_connction. Affected file is
2508 lib/silcclient/client.c.
2510 * Do not execute the KILL command for clients that are in
2511 history (ie. they are not in the network). Affected file is
2514 * Fixed KILL notify handling, client does not crash anymore.
2515 Affected file irssi/src/silc/core/silc-channels.c.
2517 * Reduced the default packet buffer size from 2048 to 1024 in
2518 lib/silccore/silcpacket.c.
2520 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2521 counter to the SKE context that is incresed when the SKE library
2522 performs async operation outside the library. If the outside
2523 process frees the SKE context and FREED status will be set
2524 and the library will detect after the sync operation that the
2525 libary is freed. The affected files are
2526 lib/silcske/silcske[_status].[ch].
2528 * Resolve the client entry information in the function
2529 silc_client_channel_message to assure that NULL pointer is not
2530 passed as client entry to the application. */
2532 * Fixed the task timeout calculation to assure that there is
2533 never negative timeouts. The affected file is
2534 lib/silcutil/silcschedule.c.
2536 * Fixed the channel user mode notification sending in server.
2537 It was sent point-to-point to the router (or to server by router)
2538 but it needs to be destined to a channel. The routines now
2539 supports sending the channel user mode notifys to the channels
2540 when announcing clients and channels. Affected files are
2541 silcd/server.c and silcd/packet_receive.c.
2543 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2544 It did not actually replace the old channel entry in the cache.
2545 Affected file lib/silcclient/client_notify.c.
2547 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2549 * Fixed a possible crash in silc_packet_send_prepare. It now
2550 assures always that there is enough space in the buffer and
2551 at the tail area of the buffer (for MAC).
2553 Fixed the inbound buffer reallocation in silc_packet_read.
2554 It was old code and did not handle the reallocation correctly.
2557 The affected file is lib/silccore/silcpacket.c.
2559 * Fixed buffer overflow in silc_parse_nickname in the file
2560 lib/silcutil/silcutil.c.
2562 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * make install generates new server keys only if there is not
2567 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2570 Added check that if the NOREPLY is set then we will not send
2571 the away message. This avoids infinite loop of away messages
2572 if both clients are away. The affected file is
2573 lib/silcclient/client_prvmsg.c.
2575 * Fixed client crash if /NICK was given without arguments.
2576 Affected file lib/silcclient/command.c.
2578 * Server does not send the invite list in INVITE command back
2579 to the client if the list was not altered. Added this notion
2580 to the protocol spec as well. Affected file silcd/command.c.
2582 Fixed possible crash in INVITE command by checking the
2583 value of silc_server_get_client_route command.
2585 * Fixed the INVITE notify type handling. The arguments are now
2586 taken in correct order and client does not crash. The affected
2587 file is irssi/src/silc/core/silc-channels.c.
2589 Removed the "Inviting xxx to channel" message from the
2590 client library away and let the application handle it.
2591 Affected file lib/silcclient/command.c. Added that message
2592 to Irssi SILC client's message formats.
2594 * Fixed CMODE command crash in client. It now checks the
2595 amount of arguments correctly and does not crash. The affected
2596 file is lib/silcclient/command.c.
2598 * Do not create new channel automatically in silc_channels_join
2599 but check whether the channel by that name already exists.
2600 Affected file irssi/silc/core/silc-channels.c.
2602 * Do not send the SERVER_SIGNOFF to router if the disconnected
2603 entity was the router. Affected file silcd/server.c.
2605 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2606 SILC client as it was missing from there.
2608 Added the handling of the KICK notify to the Irssi SILC client
2609 as it was missing. Added "you have been kicked" message to
2610 Irssi SILC client's message modules formats.
2612 Added the handing of the KILL notify to the Irssi SILC client
2613 as it was missing. Added the kill message module formats
2616 The affected file is irssi/src/silc/core/silc-channels.c.
2618 * The router did not save the channel mode the server announced.
2619 Affected file silcd/packet_receive.c.
2621 * Fixed a possible crash in INFO command in server. If the
2622 server did not provide the server info it crashed. Affected
2623 file silcd/command.c.
2625 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Fixed the GETKEY command in the server to check also the
2628 global list. Otherwise the GETKEY would not work correctly
2629 in normal SILC server. Affected file silcd/command.c.
2631 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Fixed GETKEY crash, it crashed if the command did not succseed.
2635 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2638 is now real and not just an macro interface to GMP.
2640 Removed the entire GMP from the source tree and imported new
2641 NSS MPI library instead. Reason for removing GMP is that it is
2642 extremely large and compiles extremely slow. The NSS MPI
2643 is only a few files and compiles in less than 10 seconds.
2644 The speed is also about the same as GMP. The MPI is imported
2645 to lib/silcmath/mpi.
2647 If the system has GMP installed we will still use the GMP.
2648 If it is not then the NSS MPI will be compiled.
2650 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Merged a long nickname (127 characters long) crash bugfix from
2653 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2655 * Merged a freed memory reference bugfix from Irssi CVS tree.
2656 Affected file irssi/src/core/commands.c.
2658 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2660 * Added the server's public key sving and verification to the
2661 server when performing the SKE. This was missing and the
2662 remote server's (or router's) public key was accepted without
2663 checking whether we have it previously or trust it at all.
2664 Affected file silcd/protocol.c.
2666 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * Check in the silc_server_timeout_remote if protocol is active
2669 and make sure that the protocol's final callback is called so
2670 that all memory if freed. Affected file silcd/server.c.
2672 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2674 * silc_server_whois_send_reply crashed the server if the nickname
2675 was 127 characters long. Affected file silcd/command.c.
2677 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Added sanity check to the silc_server_new_client. If the hostname
2680 is provided inside username then check that the provided hostname
2681 really is the same as the resolved one. If the hostname was not
2682 resolved then check it from the public key. Affected file is
2683 silcd/packet_receive.c.
2685 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2686 if the server disconnected us and the connection is not valid
2687 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2689 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2690 the library to the lib/silcutil/silcutil.[ch].
2692 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2694 * Close log file after open. Affected file
2695 lib/silcutil/silclog.c.
2697 * Check whether sock == NULL in silc_client_send_packet and return
2698 if it is. Affected file lib/silcclient/silcclient.c.
2700 * Check rec->entry == NULL in the Irssi SILC Client before
2701 sending the channel message. Affecte file is
2702 irssi/src/silc/core/silc-servers.c.
2704 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2706 * Merged a splitted window bugfix from Irssi CVS tree. The
2707 affected file is irssi/src/fe-text/textbuffer-view.c.
2709 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2710 It did not print nickname.
2712 * Improved the distributions system a bit.
2714 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2716 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2717 irssi/src/fe-text/gui-window.c.
2719 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2720 to in-active server. The affected file is
2721 irssi/src/silc/core/client_ops.c.
2723 * Resolve the client in USERS command reply if the entry does
2724 not have username resolved. The affected file is
2725 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2726 command to WHOIS command to really resolve stuff. The USERS
2727 is not used any more in any critical section so WHOIS can
2728 be used even though it might be slower than IDENTIFY.
2730 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2733 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2735 * Changed the protocol API a bit more consistent in the
2736 lib/silccore/silcprotocol.[ch].
2738 * Changed the following headers to ROBODoc format:
2740 lib/silccore/silcpayload.h
2741 lib/silccore/silcprotocol.h
2742 lib/silccore/silcsockconn.h
2744 All core library headers are now formatted.
2746 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2748 * Fixed a bug in Irssi SILC client; do not show that you are
2749 server/router operator if you really are not. Affected file is
2750 irssi/src/silc/core/client_ops.c.
2752 * Renamed silc_command_free_payload to silc_command_payload_free.
2753 Affected file lib/silccore/silccommand.h
2755 * Added silcmath.h to include the prototoypes of various routines
2756 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2759 * Changed the following headers to ROBODoc format:
2761 lib/silccore/silcchannel.h
2762 lib/silccore/silccommand.h
2763 lib/silccore/silcid.h
2764 lib/silccore/silcidcache.h
2765 lib/silccore/silcmode.h
2766 lib/silccore/silcnotify.h
2767 lib/silccore/silcpacket.h
2768 lib/silcmath/silcmath.h
2770 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Added checking to the server code not to start the server if
2773 ciphers and stuff are not configured properly. Affected files
2774 silcd/serverconfig.[h] and silcd/server.c.
2776 * Changed the layout of the header files of the public interfaces
2777 in the SILC libraries. The new layout supports ROBODoc
2778 documentation tool (and some others) so that it is easy to create
2779 a library reference manual. All the other headers and source
2780 code must still follow the CodingStyle document. Also source
2781 code must not include these ROBODoc stuffs, only the headers.
2782 Furthermore, all public interface headers must now be named
2783 by using `silc' prefix, example: silcapi.h, silccipher.h.
2784 Some files were renamed due to this. All the other headers
2785 must not be used as public interfaces. I will update the
2786 CodingStyle document later. Changed following headers, so far:
2788 lib/silcclient/silcapi.h
2789 lib/silccore/silcauth.h
2790 lib/silccore/silcprivate.h
2791 lib/silccrypt/silcdh.h
2793 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * Removed silc_client_packet_send_flush from the client library
2798 as it is not needed. Affected file lib/silcclient/client.[ch].
2800 * Added printing of message of unresolved authentication method
2801 to the Irssi SILC client. Added it to the module formats.
2802 Removed the same message from the client library.
2804 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2806 * Added new distribution feature, DISTLABEL. Every distribution
2807 can define own preprocessor label that can be used in the
2808 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2809 file distributions, acconfig.h.pre and prepare.
2811 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Added Makefile.defines_int to include the actual definitions
2814 for Makefile.defines.in. Tested the new distribution system,
2815 created distributions and tested installation.
2817 * Added AWAY message printing to the Irssi SILC client. Added
2818 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2820 * Added SCONNECT command to call the SILC's CONNECT command.
2821 Cannot use CONNECT directly since Irssi uses that internally.
2822 Affected file irssi/src/silc/core/silc-servers.c.
2824 Added ACTION local command. It is same as ME command but takes
2825 the channel as mandatory argument.
2827 Rewrote some of the Irssi's help files to suite for SILC
2830 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2832 * Added Makefile.defines[.in] that should for now on be included
2833 in all Makefile.am file in the source tree. That file includes
2834 all common compilation definitions for SILC source tree.
2836 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Minor changes to the ./prepare script to change the package
2839 name according the distribution name to the configure.in.
2841 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Created new distribution system. Added file `distributions'
2844 that defines all the distributions that can be created out of
2845 the SILC source tree. The ./prepare script now reads that
2846 file to determine how to prepare the distributions. The
2847 first argument to the ./prepare is the name of the distribution
2848 and second is the version of the distribution. If given
2849 without arguments it creates the default (toolkit) distribution
2850 with the default version (defined in ./prepare).
2852 All Makefile.am files that are subject to the distributions
2853 are now named as Makefile.am.pre. These are ./Makefile.am
2854 and lib/Makefile.am. Others may be changed later.
2856 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2858 * Added invite list, ban list, some key management and connection
2859 error message printing to module formats in the Irssi SILC client.
2861 * Added new silc_client_set_away_message to set the away message
2862 that is back to the person who sent private message. The
2863 affected file lib/silcclient/silcapi.h and the
2864 lib/silcclient/client_prvmsg.c.
2866 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Fixed the private message sending in the Irssi SILC client,
2869 added local command KEY to the Irssi SILC client.
2871 Added key management and key agreement message formats to the
2872 irssi/src/fe-common/silc/module-formats.[ch].
2874 Added USERS (alias WHO) printing, server/router operator
2875 indication and LIST command printing to the module formats.
2877 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * Fixed channel joining notify handling, cumode notify handling
2880 from Irssi SILC client.
2882 * Added SILC specific module-formats to the Irssi SILC client so
2883 that SILC specific message hilighting, colors etc is possible.
2884 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2886 Added channel mode, channel user mode, actions, notices,
2887 whois and whowas printing to the the module-formats.c.
2889 * Fixed a bug in channel deletion in the server. The channel
2890 is not left to the cache even if the channel founder auth mode
2891 is set when there are no users anymore on the channel. Affected
2892 file silcd/server.c.
2894 * The silc_net_localhost now resolves the entire hostname including
2895 the domain name. Affected file lib/silcutil/silcnet.c.
2897 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2899 * Changed the ask_passphrase client operation to be ascynchronous.
2900 It has now a completion callback and a context that the
2901 application must call after it has got the passphrase from
2902 the user. Affected files lib/silcclient/silcapi.h,
2903 lib/silcclient/protocol.c, lib/silcclient/command.c and
2906 Added SilcAskPassphrase callback that the application calls
2907 to deliver the passphrase to the library.
2909 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2910 The public key verification and especially a certificate
2911 verification is asynchronous procedure.
2913 Added new SILC_SKE_STATUS_PENDING status to indicate the
2914 request is pending and a callback will be called to finalize
2917 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2918 indicate that remote end did not send its public key (or
2919 certificate), even though we require it. Added check for this
2920 condition in the SKE. This was a security bug, now fixed.
2922 Defined new SilcSKEVerifyCbCompletion callback that is called
2923 when the verification process is completed.
2925 The affected files lib/silcske/silcske_status.h and
2926 lib/silcske/silcske.[ch].
2928 * Changed the verify_public_key client operation to be async
2929 as well. Defined SilcVerifyPublicKey callback that is used to
2930 indicate the success of the public key verification process.
2932 Changed the server and client to use the new async client
2935 * Changed the Irssi SILC client's internal scheduler to be called
2936 twice as many times as it used to be. As a result the client
2937 should be a bit faster now. Affected file is
2938 irssi/src/silc/core/silc-core.c.
2940 * Added support to Irssi SILC client of asynchronous public key
2941 verification and passphrase inquiry. Affected file is
2942 irssi/src/silc/core/silc-core.c.
2944 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Do not say "You have left channel %s" in client library.
2947 Moved it to the application. Affected files are
2948 lib/silcclient/command.c and silc/client_ops.c.
2950 * Fixed silc_client_get_clients. Command context was not
2951 duplicated and was freed memory in the callback. Affected
2952 file lib/silcclient/idlist.c.
2954 * Do not say "you are now talking..." on JOIN command in the
2955 client library. The appliation must handle it.
2957 * Do not say ".. changed topic to" in command reply in the
2958 client libary. The application must handle it.
2960 * Fixed TOPIC command sending in the client library.
2962 * Fixed a memory leak in silc_client_command_free in the file
2963 lib/silcclient/command.c.
2965 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Imported a modified version of Irssi client to the source tree.
2968 The Irssi will be used to create a new client called
2969 Irssi SILC. Imported to irssi/.
2971 Added silc_core_init_finish function to the Irssi. Affected
2972 file irssi/configure.in.
2974 A lot changes in the Makefile.ams around the irssi tree.
2976 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Do not rehash if the new size is same as the old size of the
2979 hash table, in the silc_hash_table_rehash*. The affected file
2980 lib/silcutil/silchashtable.c.
2982 * Replaced hash_table_del_by_context calls from the server
2983 (when channel->user_list and client->channels) to the
2984 hash_table_del as it is sufficient and faster.
2986 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * Added silc_hash_table_list, silc_hash_table_get and the
2989 SilcHashTableList structure to provide an alternative way to
2990 traverse the hash table. The affected files are
2991 lib/silcutil/silchashtable.[ch].
2993 * Changed the server's idlist routines to use the hash table
2994 routines to optimize the code.
2996 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * Replaced the client entry's `channel' list and channel entry's
2999 `user_list' list to hash tables for optimized lookup. Changed
3000 the code to use the hash table interface around the code.
3001 Affected file lib/silcd/idlist.[ch].
3003 * Added `auto_rehash' boolean argument to the function
3004 silc_hash_table_alloc to indicate whether the hash table should
3005 auto-rehash when it thinks is appropriate time. It will
3006 increase the hash table size if the there is twice as much
3007 entries in the table than the size of the table, and will
3008 decrease the size if there are twice as less entries than
3009 the size of the table.
3011 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3015 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3017 * silc_idcache_purge_by_context deletes the entry now by context
3018 as it is supposed to do. Affected file lib/silccore/idcache.c.
3020 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3021 client is not anymore valid (WHOWAS givens the info) and not
3022 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3024 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3026 * Removed the `data' and `data_len' arguments from the ID Cache
3027 interfaces and added `name' argument. ID Cache does not handle
3028 anymore the binary data only a names associated with given ID.
3030 * When hashing a Client ID with silc_hash_id the entire ID is
3031 not hashed anymore, instead only the hash of the Client ID is
3032 hashed. This way we can access the Client ID from the cache
3033 with Client ID but with the hash of the ID (which is a hash of
3034 the nickname) as well without any difference in performance.
3036 Added also silc_idcache_find_by_id_one_ext to do one on one
3037 searching when we have the actual ID. Added also function
3038 silc_hash_client_id_compare. The affected files are
3039 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3041 * When hashing the name associated with a ID it is always done
3042 in lowercase. This way we can access the cache without worrying
3043 about case-sensitivity, even though, for example nicknames are
3046 * Fixed a bug in server with channel message sending. It put
3047 wrong ID type as destination ID. The affected file
3048 silcd/packet_send.c.
3050 * silc_idcache_del_by_context now deletes from all hash tables
3051 by context. Affected file lib/silccore/idcache.c.
3053 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Changed the client library to use the new ID Cache interface.
3056 Changes around the source tree.
3058 * Added silc_hash_table_rehash_ext to rehash with specific
3059 hash function. Affected file lib/silcutil/silchashtable.[ch].
3061 * Added silc_hash_string_compare to compare two strings in the
3062 hash table. Affected file lib/silcutil/silcutil.[ch].
3064 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Added new function silc_idcache_del_by_context into the
3067 lib/silccore/idcache.[ch].
3069 * Changed the server's ID list routines to use the new ID Cache
3070 interface. Changes around the source tree.
3072 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Added silc_hash_table_del[_by_context]_ext functions in to the
3075 lib/silcutil/silchashtable.[ch].
3077 Removed silc_hash_table_find_all* routines and added new
3078 silc_hash_table_find_foreach to replace them.
3080 Added silc_hash_table_replace_ext function as extended
3081 replacing function. Separated the simple hash table interface
3082 from the extended hash table interface in the file
3083 lib/silcutil/silchashtable.h.
3085 * Fixed minor bugs and changed it to use some of the new
3086 hash table functions in lib/silccore/idcache.c
3088 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * Added new function silc_hash_table_find_all to return all keys
3091 in the hash table by the specified key. As the hash table is
3092 collision resistant it also makes it possible to have several
3093 duplicate keys in the hash table. This function may be used to
3094 find all of the keys from the hash.
3096 Added user_context arguments to the SilcHashFunction,
3097 SilcHashCompare and SilcHashDestructor to deliver user specified
3100 Added new fuctions silc_hash_table_find[_all]_ext to do
3101 extended lookup with specified hash and compare functions and
3102 specified user contexts.
3104 Added new function silc_hash_table_add_ext to add the key
3105 with specified hash function and user context.
3107 Added new function silc_hash_table_foreach to traverse all
3108 entrys in the hash table. Added SilcHashForeach callback
3111 Added new function silc_hash_table_del_by_context to delete
3112 the entry only if the context associated with the key matches.
3114 Affected files are lib/silcutil/silchashtable.[ch].
3116 * Removed silc_hash_[server/client/channel]_id and added just
3117 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3118 silc_hash_id_compare to compare two ID's using as the hash table
3119 comparison function. Added also silc_hash_data to hash
3120 binary data and silc_hash_data_compare to compare it.
3122 * Removed silc_idlist_find_client_by_hash as it is not needed
3123 anymore. Affected file silcd/idlist.[ch].
3125 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3126 to use internally the SilcHashTable. The new ID Cache is a lot
3127 faster than the old one. Some of the ID Cache interface was also
3128 rewritten and obsolete and stupid functions were removed.
3130 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Added entry_count field to the SilcHashTable to keep the number
3133 of the entries in the table. Implemented the function
3134 silc_hash_table_rehash. Added new function
3135 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3137 Fixed a minor bug in silc_hash_table_free.
3139 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3140 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3141 into the lib/silcutil/silcutil.[ch].
3143 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Implemented a collision resistant hash table into the
3146 lib/silcutil/silchashtable[ch]. See the header and the source
3147 for the SilcHashTable API.
3149 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Merged dotconf version 1.0.2 into lib/dotconf.
3153 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3155 * Do not compile anything in lib/silcsim/* if the SIM support
3156 is not enabled. The tree should now compile without problems
3159 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Compiled the SILC under cygwin. Compiled and tested briefly
3162 without problems. More tests needed. The SIMs didn't compile
3165 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3167 * Fixed possible crash in silc_get_username in the
3168 lib/silcutil/silcutil.c.
3170 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3172 * Fixed a va_arg in silc/client_ops.c.
3174 * Oops, RC5 routines were named AES and caused some problems
3175 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3177 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3179 * Added new SilcIDIP structure into the lib/silccore/id.h and
3180 replaced the old `ip' fields from all SILC ID's to that type.
3181 This is a step towards IPv6 support.
3183 The silc_id_get_len takes now the ID as an extra argument.
3184 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3185 both IPv4 and IPv6 based ID's.
3187 The affected files are lib/silccore/id.[ch] and other files
3188 around the tree using these routines.
3190 * Removed the ID length arguments in server from various
3191 silc_server_send_notify_* routines -> they are not needed
3194 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3196 * Fixed memory leak in silc_encode_pem_file in the file
3197 lib/silcutil/silcutil.c.
3199 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * Check minor version as well in the SKE. Affected files are
3202 silcd/protocol.c and lib/silcclient/protocol.c.
3204 * Added --identifier option to the server so that an identifier
3205 can be when creating the public key for the server. Affected
3206 file is silcd/silcd.c.
3208 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3209 lib/silccrypt/silcpkcs.c.
3211 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Register default ciphers and stuff when using -C option with
3214 the server. Affected file sildc/silcd.c.
3216 * Put back the servers public key filename format, it is better
3217 than the new one. For now, the client keys are saved with the
3218 new filename format. The affected file silc/client_ops.c.
3220 * Implemented the Cipher API for the rest of the ciphers that
3221 did not implement it or implemented it the wrong way.
3223 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3225 * Register default ciphers and stuff when using the -S option
3226 in the client. Affected file silc/silc.c. Same also when
3227 creating new key pair with -C option.
3229 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Fixed the silc_verify_public_key client operation function to
3232 save the public keys differently. The fingerprint is now
3233 used as filename and not the hostname. This way also the
3234 client keys are saved uniquely and not with hostnames. The
3235 affected file is silc/client_ops.c.
3237 * Trimmed the silc_hash_fingerprint function to remove extra
3238 whitespaces from the end of the fingerprint. The affected
3239 file is lib/silccrypt/silchash.c.
3243 * Added silc_cipher_register_default function to register all
3244 default ciphers. It can be used when configuration files
3245 does not exist and the application does not want any specific
3246 ciphers in any specific order.
3248 The SilcDList is now used as silc_cipher_list dynamically
3249 allocated cipher list. Removed the static list all together
3250 and now all ciphers must be allocated to the dynamic list.
3251 The silc_cipher_alloc routine was changed to check only the
3254 All silc_cipher_* routines that used to return int returns
3257 The affected files lib/silccrypt/silccrypt.[ch].
3259 * The same thing was done to silc_hash_* as for silc_cipher_*
3260 routines. Affected files lib/silccrypt/silchash.[ch].
3262 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3263 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3264 Added also silc_pkcs_[un]register[_default] functions.
3265 Removed the data_context from the PKCS API.
3267 * Added silc_hmac_register_default function to register default
3268 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3269 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3270 to unregister all hmacs at once.
3272 * Register the default ciphers, hash functions, PKCSs and HMACs
3273 if client's configuration file does not exist. The affected
3276 * The client did not load the hash functions from the SIM
3277 modules at all. Added support for this. Affected file is
3278 silc/clientconfig.c.
3280 * When decoding public key with silc_pkcs_public_key_decode, check
3281 the supported algorithm only if PKCS are registered. Affected
3282 file lib/silccrypt/silcpkcs.c. The same was done with the
3283 silc_pkcs_private_key_decode.
3285 * Fixed the SILC List routines to keep the list always in order.
3286 It used to change the list's order when traversing the list but
3287 not it preserves the order. Affected file lib/trq/silclist.h.
3289 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Added the client library to use the SilcSocketConnection's
3292 reference counter (by silc_socket_dup) to prevent the bug that
3293 the socket object may be freed underneath async operation.
3295 * The name resolv library checking fixes in the configure.in.pre.
3298 * Created new version of the protocol drafts for future
3299 development. The -03 drafts are the ones that will be changed
3300 in the trunk now and the -02 will remain as they are.
3302 * Send list of CUMODE notifys to the router when announcing
3303 the channel users to the router. Affected file silcd/server.c.
3304 If the router receiving channel founder CUMODE for a channel
3305 that already has channel founder it will send CUMODE notify
3306 to the sender to remove the channel founder rights from the
3307 announced client. Affected file silcd/packet_receive.c.
3309 * The CUMODE notify may now use Server ID as well as the entity
3310 who changes the mode. Updated protocool specs.
3312 * Updated INSTALL and README files.
3314 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * New web pages in the http://silc.pspt.fi. The pages was
3321 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * Implemented the [DenyConnectin] config section in the server.
3324 Added silc_server_config_denied_conn to check whether incoming
3325 connection is denied. Affected file silcd/serverconfig.[ch].
3327 * Do not check the ports when checking the incoming configuration
3328 data if the port is 0, meaning any. Affected file is
3329 silcd/serverconfig.c.
3331 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Fixed buffer overflow in silc_string_compare in the file
3334 lib/silcutil/silcutil.c.
3336 * Fixed double free in silc_server_command_leave in the file
3339 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Fixed the version checking in the server. Affected file is
3344 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3346 * Fixed the configuration data fetching when accepting new
3347 connections in the server. Affected file silcd/server.c.
3349 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3351 * Added `sender_entry' argument to the function
3352 silc_server_packet_relay_to_channel so that we can check
3353 whether some destination actually belongs to the same route
3354 the sender belongs (ie, we must not resend the packet to the
3355 sender). Affected file silcd/packet_send.[ch].
3357 * Added `servername' field to the SilcClientEntry in the server
3358 to hold the name of the server where client is from. Affected
3359 file is silcd/idlist.h.
3361 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Moved the channel message encrypting in the router betwen
3364 router connections from silc_server_channel_message to the
3365 silc_server_packet_relay_to_channel since we want to check
3366 whether we have anybody channel before encrypting anything.
3367 Affected files silcd/packet_[receive/send].c.
3369 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * Fixed the [AdminConnection] server config section to support
3372 multiple entries. Affected file silcd/serverconfig.c.
3374 * Added support into the server to check the validity of the
3375 incoming connection before executing any KE or authentication
3378 * The connection configuration is now saved to the KE and
3379 connection auth protocol contexts and not fetched anymore in
3380 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3382 * The local hosts listenning address and port is also resolved
3383 now when starting the server. We want to have the socket object
3384 to include the real address and port for the listener. Added
3385 new function silc_net_check_local_by_sock into the files
3386 lib/silcutil/silcnet.[ch].
3388 * Fixed a broadcast bug in server -> do not broadcast if we
3391 * Fixed a routing bug. Do not route broadcast packets ever.
3392 Broadcast packets must be processed always and not routed since
3393 they may be destined to some other host than yourself and thus
3394 would get routed without no good reason. Affected file is
3397 * Added function silc_server_config_is_primary_route to check
3398 whether primary router connection has been configured (a router
3399 configuration that we are initiating). If there is not, we
3400 will assume that there is only two routers in the SILC network
3401 and we will use the incoming router connection as our primary
3402 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3404 * Changed the order of the broadcasting. Broadcast _after_ the
3405 packet has been processed not before. Affected file is
3408 * Fixed a [ClientConnection] parsing bug. The port was never
3409 parsed correctly thus resulting to port 0. Affected file
3410 silcd/serverconfig.c.
3412 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3413 argument and did not set the broadcast packet flag. Affected
3414 file silcd/packet_send.c. Fixed same bug in the function
3415 silc_server_send_notify as well.
3417 * If we receive NEW_ID packet for our own ID in the server, ignore
3420 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Removed the nickname from the Private Message Payload.
3425 Updated the code and the protocol specs.
3427 * Updated protocol specs for submitting to the IETF.
3429 * Tweaked the Random Number Generator a bit. Affected file
3430 lib/silccrypt/silcrng.c. Exported a new function
3431 silc_rng_[global]_add_noise which can be used to add more
3434 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Do not parse packets with different timeout when protocol
3437 is active -> may cause problem with rekey. Affected file
3440 * When server receives signoff notify it must not create
3441 new channel key if the client is on any channels since the
3442 sender of the signoff notify will create it.
3444 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Added printing of error messages during SKE protocol from the
3447 failure packet sent by server during SKE. Affected file
3450 * Removed the client's failure_callback handling with timeout
3451 and handle it immediately when received.
3453 * The SKE library returned wrong type in SUCCESS and FAILURE
3454 packets. They must be 32 bit MSB not 16 bit MSB.
3456 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Ok, rewrote the logic of the re-key and now it seems to work.
3459 I tested it on high traffic with frequent re-keys without
3460 problems. Added hmac_receive (and renamed hmac to hmac_send)
3461 in SilcClientConnection in lib/silcclient/client.h and
3462 in SilcIDListData in silcd/idlist.h. Also, removed the
3463 SilcPacketParserContext's cipher and hmac fields as they are
3464 not needed anymore and actually caused some problems when
3465 the ciphers and hmac's changed underneath the packet parser.
3467 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * If re-key protocol is active then process the incoming packets
3470 synchronously since we must assure that icoming packets encrypted
3471 with the old key is processed before the new keys is set to
3472 use. This is true other packets than for REKEY packets.
3473 Affected file silcd/server.c. The same was done to client library
3474 as well, affected file lib/silcclient/client.c.
3476 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Fixed bug in client and server to accept the force send if
3479 the packet is send from silc_[server/client]_packet_process
3480 function. Otherwise the packets are never delivered, oops.
3482 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Disable force sending of packets when REKEY protocol is active.
3485 We must assure that no packet is sent directly when rekey is
3486 performed. All packets must be sent through packet queue.
3487 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3488 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3489 function is silc_[server/client]_packet_send_real to check
3492 * Replaced the SIM paths from example config files to
3493 /usr/local/modules. Also, make install creates now
3494 /usr/local/silc/logs directory to hold all the SILC server
3497 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3499 * Made the configure.in.pre work on Solaris. Patch by salo.
3501 * Made all ciphers compatible with non-x86 machines. Defined
3502 CBC mode macros into lib/silccrypt/ciphers_def.h.
3504 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3506 * Fixed the make install.
3508 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * When MAC computation fails the silc_packet_decrypt returned 0
3511 even though it was supposed to return -1. Fixed this. The
3512 affected file is lib/silccore/silcpacket.c.
3514 * Do not replace the config files in /etc/silc (in make install)
3515 if they already exist. Affected file ./Makefile.am.
3517 * Do not send re-key packets immediately but through packet queue.
3518 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3520 * Changed silc_net_check_host_by_sock to return FALSE if the
3521 IP/DNS could not be resolved. Though, it returns the IP address
3522 now even if it could not resolve it (but returns also FALSE).
3523 Affected file lib/silcutil/silcnet.[ch].
3525 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3527 * Added silc_pkcs_decode_identifier to decode the public key's
3528 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3529 Added also silc_pkcs_free_identifier. Added also new context
3530 SilcPublicKeyIdentifier.
3532 * Added -S option to the silc client. It is used to dump the
3533 contents of the specified public key file.
3535 * Changed the PKCS api to return the public key length when
3536 setting the public key.
3538 * Fixed a fatal bug in the public and private key file loading.
3539 Affected file lib/silccrypt/silcpkcs.c.
3541 * Execute the packet parsing for client with zero (0) timeout
3542 if the protocol is active. Affected file silcd/server.c.
3544 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * Made the key generation options to the silcd program. Added
3547 -C option, equivalent to client's option.
3549 * Added new [ServerKeys] config section to the server. It
3550 configures the server's public and private key.
3552 * Defined generic Public Key Payload into the protocol
3553 specification to send specific type of public keys and
3556 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3557 public key or certificate.
3559 * Implemented the GETKEY command to the server and to the
3560 client library and on user interface.
3562 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Made preliminary `make install' work.
3566 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Added SilcServerRekey context into silcd/idlist.h.
3570 * Added the PFS support as defined in the specification to the
3571 SKE protocol. Affected files lib/silcske/*.c.
3573 * Added `ske_group' field to the SilcServerRekey context to hold
3574 the number of the SKE group that is used with PFS in re-key.
3575 Affected file silcd/idlist.h.
3577 * Added PFS re-key support to the server. Affected file is
3580 * Added silc_protocol_cancel to cancel execution of the next
3581 state of the protocol. Affected file is
3582 lib/silccore/silcprotocol.[ch].
3584 * Added the re-key support with and without PFS to the client
3585 library. Re-key is performed once in an hour, by default.
3587 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3588 Added silc_client_rekey_callback and silc_client_rekey_final.
3589 Affected files are lib/silcclient/protocol.[ch] and
3590 lib/silcclient/client.[ch].
3592 * Removed the `hmac_key' and `hmac_key_len' fields from the
3593 SilcClientConnection structure; not needed. Affected file is
3594 lib/silcclient/client.h.
3598 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Do not ask whether user wants to use the negotiated private key
3601 for private messages, just use it. Affected file is
3602 silc/local_command.c.
3604 * Added `send_enc_key' and `enc_key_len' fields to the
3605 SilcIDListData structure since they are needed in the re-key
3606 phase. Affected file is silcd/idlist.[ch].
3608 * Implemented the simple re-key protocol into the server.
3609 Affected files silcd/server.c and silcd/protocol.[ch]. The
3610 re-key will be performed once in an hour, by default.
3612 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3613 Added silc_server_rekey, silc_server_rekey_callback and
3614 silc_server_rekey_final.
3616 * Removed Tunneled flag from the protocol. Updated the code
3617 and the specifications.
3619 * Adde `pfs' field to the SilcIDListData to indicate whether
3620 the PFS is to be performed in the re-key. Affected file is
3623 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3626 int64 of at least the xintXX size. If void * is less that 4
3627 bytes uint32 * will be used. Defined bool as boolean.
3629 * Changed _ALL_ unsigned long and unsigned int to uint32,
3630 unsgined short to uint16 in the source tree.
3632 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3633 not handle clients that has entry->data.registered == FALSE.
3634 They are not in the network anymore. Affected file is
3637 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Implemented the sending of the SERVER_SIGNOFF notify in the
3640 server. Affected file is silcd/server.c.
3642 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3643 Added also silc_notify_payload_encode_args into the
3644 lib/silccore/silcnotify.[ch].
3646 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3647 Affected file silcd/packet_receive.c.
3649 * Implemented the SERVER_SIGNOFF notify handling in the client
3650 library. Affected file lib/silcclient/client_notify.c. Also,
3651 implemnted the printing of the SERVER_SIGNOFF info to the
3652 application. Affected file silc/client_ops.c.
3654 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3655 if the deleting was successful. Affected file silcd/idlist.[ch].
3657 * Added support for public key authentication in the connection
3658 authentication protocol in the client library. Affected file
3659 lib/silcclient/protocol.c.
3661 * Changed the server's silc_idlist_get_clients_by_* interface
3662 to support already allocated array so that new entries may be
3663 added to pre-allocated array. Affected file silcd/idlist.[ch].
3664 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3665 and command replies.
3667 * All command reply functions in the server now calls the
3668 pending command callback even if error occured. This way the
3669 error will be delivered to the client as well. Affected files
3670 silcd/command.c and silcd/command_reply.c.
3672 * Fixed INFO command to return local server's info if no server
3673 was provided. Affected file lib/silcclient/command.c.
3675 * Removed RESTART command for good. Updated the code and the
3678 * Rewrote parts of the task system. It is a bit simpler now.
3679 Removed unsued task priorities. The affected files are
3680 lib/silcutil/silctask.[ch].
3682 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Moved the USERS printing from the library to the application.
3685 Affected files lib/silcclient/command.c and silc/client_ops.c.
3687 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Added channel key re-key support. The re-key is perfomed
3692 only by the router and is done once in an hour. Added `rekey'
3693 field to the SilcChannelEntry in the server. Affected files
3694 silcd/server.c and silcd/idlist.h.
3696 * Added silc_task_unregister_by_context into the file
3697 lib/silcutil/silctask.[ch].
3699 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3701 * Added SILC_UMODE_GONE mode to indicate when the client is not
3702 present in the SILC network. Added also support to the local
3703 command AWAY that will set this mode. Added support of showing
3704 "xxx is gone" in WHOIS command. The USERS command shows the
3705 gone status as well.
3707 * Fixed setting server and router operator privileges in the
3708 server's UMODE command. Affected file silcd/command.c.
3710 * Merged the SKE KE1 and KE2 payloads into one payload. The
3711 new KE payload is equivalent to the old KE2 payload.
3713 Cleaned up the SKE Start Payload parsing. It now uses the
3714 simple buffer unformatting to do the parsing. A lot faster
3717 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3718 to the SKE that is used to indicate whether both of the SKE
3719 parties should perform authentication. By default only the
3720 responder performs authentication. By setting this flag also
3721 the initiator must do authentication. By default it is unset
3722 since in normal SKE case, client to server connection, only
3723 the responder should do authentication. When doing SKE between
3724 two clients both should perform authentication. Updated the
3725 code and the protocol specs.
3727 * A little fix to IDENTIFY command in the server. Search the
3728 client first by hash not nickname. Affected file is
3731 * Fixed the silc_client_close_connection to support closing
3732 the client to client connections wihtout deleting too much
3733 data. Affected file lib/silcclient/client.c.
3735 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3736 are received if protocol used to be active but is not anymore
3737 the application would crash due to NULL pointer dereference.
3738 Affected files silcd/server.c and lib/silcclient/client.c.
3740 * Added `hash' field to the SilcClientConnection to include
3741 the hash function negotiated in the SKE protocol.
3743 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3744 to set the channel founder authentication data. A client can
3745 claim the founder rights later by providing the authentication
3746 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3747 This way the channel founder can regain the channel founder
3748 privileges even it is left the channel. This works only on
3749 local server and the client must be connected to the same
3750 server to be able to regain the founder rights. Updated the
3751 protocol specs accordingly.
3753 Added support to the CMODE command in the client to set the
3754 founder auth data. Read the README to see how to set it.
3756 Added support to the CUMODE command to claim the founder
3757 rights. Read the README to see how to do it.
3759 Added support for the founder authentication to the Channel
3760 Entry in the server. Affected file silcd/idlist.h.
3762 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3763 server's CMODE command. Affected file silcd/command.c.
3765 * Added the following new functions into lib/silccore/silcauth.[ch]:
3766 silc_auth_get_method and silc_auth_get_data.
3768 * The server now saves the remote hosts public key to the
3769 SilcIDListData pointer. Affected file silcd/protocol.c.
3771 * The normal server now does not remove the channel entry from
3772 the cache if the founder authentication data is set. It used
3773 to remove it if the founder was the last one on the channel on
3774 the server and left the channel. The auth data is saved and
3775 if the channel is re-joined later the old entry is used with
3776 the old auth data. Affected files silcd/command_reply.c and
3779 * Removed the `pkcs' field from the SilcIDListData structure
3780 in the server; it is not used. Affected file silcd/idlist.h.
3782 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3784 * Fixed packet processing on slow links. Partial packets were
3785 never re-processed because the incoming data buffer was cleared
3786 by the application. Application must not directly clear the
3787 sock->inbuf, the packet processing routines handle it. Fixed
3788 this in client library and in server.
3790 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Fixed the WHOIS and IDENTIFY send reply function to really
3793 check whether to send list or just one entry. Affected file
3796 * Cleaned up the LEAVE command's channel key distribution. The
3797 affected file silcd/command.c.
3799 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3800 can enforce the channel mode as well. In that case the ID
3801 includes the ID of the server. The code now enforces the
3802 mode change if the router have different mode than the server.
3804 * The notify client operation with CMODE_CHANGE notify can now
3805 return NULL client_entry pointer if the CMODE was not changed
3806 by client. Application must check for this.
3808 * Added <Server ID> argument to INFO command to support server
3809 info fetching by Server ID.
3811 * Added silc_server_announce_get_channel_users to get assembled
3812 packets of channel users of the specified channel. Affected
3813 file silcd/server.[ch].
3815 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3816 was freed underneath the ID Cache.
3818 * Re-announce clients when the server received CHANNEL_CHANGE
3819 notify from the router. Affected file silcd/packet_send.c.
3821 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3824 crashed since it did not handle the fact that there is no cipher
3825 called "3" and didn't check the error condition. Now fixed.
3827 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3828 flag. It can be used to send message requests.
3830 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Implemented the RESTART command in the client.
3834 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3835 notice type messages. Added notice printing to the user
3838 * The channel keys are not re-generated if the channel's mode
3839 is PRIVKEY, ie private key on the channel exists. Affected
3840 files silcd/server.c and silcd/command.c.
3842 * Fixed a little bug in channel message delivery when channel
3843 private keys are set in the server. Affected file is
3844 silcd/packet_send.c.
3846 * Changed the setting on channel->on_channel = TRUE from the
3847 silc_client_save_channel_key to the JOIN command reply. The
3848 key payload is not received if the private channel key is set.
3849 Affected file lib/silcclient/command_reply.c and the
3850 lib/silcclient/client_channel.c.
3852 * When the CMODE_CHANGE notify is sent and the channel private
3853 key mode is removed the channel key must be re-generated in
3854 other cells as well. Added this support for the router in the
3855 silcd/packet_receive.c.
3857 * Added new local command NOTICE to send notice message on
3858 channel. Affected file silc/local_command.[ch].
3860 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Added new local command ME to the client. It is used to send
3863 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3864 some action. Affected file silc/local_command.[ch].
3866 * Changed channel_message and private_message client operations
3867 to deliver the message flags to the application. Added also
3868 the `flags' arguments to the silc_client_send_channel_message
3869 and silc_client_send_private_message functions. Affected file
3872 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Redefined the Private Message Payload to support private message
3875 keys and to support the new private message flags. Updated
3876 the protocol specs. Flags makes it possible to have for example
3877 CTCP style messages.
3879 * Added new type SilcPrivateMessagePayload and defined an API
3880 for it in the lib/silcclient/silcprivate.[ch].
3882 * Tested private message private keys successfully. Tested the
3883 private message key set, unset and list commands with the new
3886 * Redefined the Channel Message Payload to include the channel
3887 message flags (equal with private message flags) to support
3888 for example CTCP style messages.
3890 * Defined some of the message (for channel and private message)
3891 flags. Updated the protocol specs and added the flags to the
3892 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3894 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3896 * Added SilcKeyAgreementStatus type to the key agreement routines
3897 to indicate the current status and error if one occured.
3898 The status types are defined in the lib/silcclient/silcapi.h.
3900 * Added new local command KEY that is used to set and unset private
3901 keys for channels, set and unset private keys for private messages
3902 with remote clients and to send key agreement requests and
3903 negotiate the key agreement protocol with remote client. The
3904 key agreement is supported only to negotiate private message keys,
3905 it currently cannot be used to negotiate private keys for channels,
3906 as it is not convenient for that purpose.
3908 * Fixed a minor pending callback setting bug in the function
3909 silc_client_get_client_by_id_resolve, now the function works.
3910 Affected file lib/silcclient/idlist.c.
3912 * Added function silc_net_get_local_port to get local bound
3913 port by socket. Added to lib/silcutil/silcnet.[ch].
3915 * Added `sockets' and `sockets_count' fields to the SilcClient
3916 object. They hold the sockets of the listenning sockets in
3917 the client. Listenning sockets may be for example the key
3918 agreement server. Affected file lib/silcclient/client.[ch].
3919 Added functions the silc_client_add_socket and the
3920 silc_client_del_socket. They are exported to the application
3923 * Added ~./silc/clientkeys to support other client's public keys.
3925 * Renamed verify_server_key client operation to verify_public_key
3926 and added one argument to indicate the type of the connection
3927 (server, client etc.).
3929 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3931 * Added silc_server_connection_auth_request to handle the
3932 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3933 silcd/packet_receive.[ch].
3935 * Added silc_server_send_connection_auth_request into the
3936 silcd/packet_send.c to send the connection auth request packet.
3938 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3941 * Fixed the public key authentication in responder side in the
3942 server. The `auth_data' pointer includes the SilcPublicKey
3943 not the path to the public key. Affected file silcd/protocol.c.
3945 * Implemented the public key authentication in the initiator side
3946 in the server. Affected file silcd/protocol.c.
3948 * Removed the [RedirectClient] config section from the server
3949 configuration. Is not needed and I don't want to implement it.
3951 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Cleaned up the CMODE command in the server. It now works
3954 correctly and supports all the modes defined in the protocol.
3955 Affected file is silcd/command.c.
3957 * Added `hmac_name' field to the SilcChannelEntry in the server
3958 to hold the default HMAC of the channel. It can be set when
3959 creating the channel (with JOIN command). Affected files
3962 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3963 type to indicate the change of the current cipher and hmac
3964 on the channel. Client can safely ignore the <cipher> argument
3965 (if it chooses to do so) since the CHANNEL_KEY packet will
3966 force the channel key change anyway. The <hmac> argument is
3967 important since the client is responsible of setting the new
3968 HMAC and the hmac key into use.
3970 * Fixed the CMODE command in the client library as well.
3972 * Tested CMODE command in router environment successfully.
3974 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Show the version of the remote client (or server) when connecting
3977 to the server. It is logged to the log file. Affected file
3978 is silcd/protocol.c.
3980 * Fixed the KILLED notify handling in the client library. The
3981 client must be removed from all channels when receiving the
3984 Also, do not remove the client entry when giving the KILL
3985 command but when the KILLED notify is received.
3987 * Removed silc_idlist_find_client_by_nickname from the server.
3988 Not needed anymore. Affected files silcd/idlist.[ch].
3990 * Implemented the CHANNEL_CHANGE notify type handling to the
3991 server. Affected file silcd/server.c.
3995 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Added silc_server_send_notify_invite to send the INVITE
3998 notify between routers.
4000 * Implemented the INVITE command correctly to the server.
4002 * Implemented the INVITE notify type handling in the server.
4004 * Implemented the INVITE command to the client library and on the
4007 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Added function silc_server_get_client_resolve to find the
4010 client entry by ID from all ID lists and then resolve it
4011 (using WHOIS) if it cannot be found. Affected file is
4014 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Implemented the BAN command to the client library.
4018 * The JOIN command in the server now checks the invite list
4021 * Changed the silc_command_reply_payload_encode_va and the
4022 silc_command_payload_encode_va to support that if argument is
4023 NULL it ignores and checks the next argument. Affected file
4024 lib/silccore/silccommand.c.
4026 * Added silc_server_send_notify_ban to send the BAN notify
4027 type between routers.
4029 * Chaned the silc_notify_payload_encode to support that if
4030 argument is NULL it ignores and checks the next argument.
4031 Affected file lib/silccore/silcnotify.c.
4033 * Tested ban lists in router environment successfully.
4035 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Implemented BAN command to the server, in silcd/command.[ch].
4039 * Removed the BAN and INVITE_LIST modes from the CMODE command
4042 * Added function silc_string_match to regex match two strings.
4043 Affected files lib/silcutil/silcutil.[ch].
4045 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Redefined parts of the SilcChannelEntry in the server to support
4048 the new ban and invite lists.
4050 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Redefined the INVITE command. The same command can be used to
4053 invite individuals to the channel but also to manage the invite
4054 list of the channel (to add to and remove from the invite list).
4055 Updated the protocol specs.
4057 * Added new command SILC_COMMAND_BAN that can be used to manage
4058 the ban list of the channel. Updated the protocol specs.
4060 * Removed the channel modes: the SILC_CMODE_BAN and the
4061 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4062 in the CMODE command. The equivalent features are now available
4063 using INVITE and BAN commands. Updated the protocol specs.
4065 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4066 in the network about change in the current ban list. The notify
4067 type is not used by the client.
4069 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4070 support the invite lists.
4072 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4074 * Added new function silc_string_regexify that converts string
4075 including wildcard characters into regex string that can
4076 be used by the GNU regex library. Added into the file
4077 lib/silcutil/silcutil.[ch].
4079 Added silc_string_regex_combine to combine to regex strings
4080 into one so that they can be used as one regex string by
4081 the GNU regex library. Added into the file
4082 lib/silcutil/silcutil.[ch].
4084 Added silc_string_regex_match to match two strings. It returns
4085 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4087 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Imported GNU regex to the soruce tree into lib/contrib.
4090 Fixed some compiler warning from the regex.c.
4092 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Fixed MOTD command in the server to work in router environment.
4096 * Fixed the MOTD command in the client library to support
4097 the server argument in the command.
4099 * Added `nickname_len' argument to the silc_idlist_add_client
4100 in the server, as the `nickname' argument may be binary data
4103 * Added silc_idlist_get_channels to return all channels from
4106 * Implemented LIST command to the server. Affected file is
4109 * Implemented the LIST command to the client library and on the
4112 * Added [<user count>] argument to the LIST command reply.
4113 With private channels the user count is not shown.
4115 * Updated TODO and README.
4117 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * The client entry's data.registered must be TRUE even with
4120 global client entry on global client list. The data.registered
4121 is used to check whether the client is anymore in the network,
4122 for example with WHOWAS command so it must be valid.
4124 * Fixed the WHOWAS command in the server. It now actually works
4125 in router environment. Added function into silcd/command_reply.c
4126 silc_server_command_reply_whowas_save.
4128 * Added silc_idlist_purge function to the silcd/idlist.c
4129 to periodically purge the ID Cache.
4131 * Fixed INFO command in the server. It works now in router
4132 environment. Added <server name> argument to the INFO command
4133 reply. Updated the protocol specs.
4135 * Fixed minor bug in silc_idcache_purge to not purge if the
4136 expire value is zero.
4138 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4139 they were buggy because of the WHOWAS information.
4141 * Fixed local command MSG to handle the async resolving of
4142 the remote client properly. It used to fail the first MSG.
4143 Affected file silc/local_command.c.
4145 * Added `data_len' field to SilcIDCache context.
4147 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Update TODO. Todo in commands in the server.
4151 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4154 used by routers as broadcast packet to inform other routers
4155 about the changed user mode.
4157 Implemented the notify handling in the server. Affected file is
4158 silcd/packet_receive.c. Added the function
4159 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4161 * Added new generic Channel Payload and deprecated the New Channel
4162 Payload. The New Channel Payload is now the generic Channel
4165 * Added new argument `mode' to the silc_server_send_new_channel
4166 as it is required in the Channel Payload now.
4168 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4169 and created a new and real SilChannelPayload to represent the
4170 new generic Channel Payload. Implemented the encode/decode
4171 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4173 * Added silc_server_get_client_channel_list to return the list
4174 of channels the client has joined for WHOIS command reply.
4175 Affected file silcd/server.[ch].
4177 * Implemented the channel list sending in the WHOIS command reply
4178 in server and in the client.
4180 Implemented the channel list displaying on the user interface
4181 as well. Affected file silc/client_ops.c.
4183 * Added silc_channel_payload_parse_list to parse list of Channel
4184 Payloads. It returns SilcDList list of SilcChannelPayloads.
4185 Client for example can use this function to parse the list of
4186 channels it receives in the WHOIS command reply. The caller
4187 must free the list by calling silc_channel_payload_list_free.
4188 Affected files lib/silccore/silcchannel.[ch].
4190 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Added one new argument <user mode> to the WHOIS command reply
4193 to return the mode of the user in SILC. Updated the protocol
4196 Implemented it to the server and client.
4198 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Fixed the mode printing on the user interface on joining.
4201 Affected file silc/client_ops.c.
4203 * Implemented the UMODE command and user modes in general to the
4204 client library and to the user interface.
4206 * Implemented the UMODE command to the server.
4208 * The server now sends UNKNOWN_COMMAND error status if client sends
4209 unknown command. Affected file silcd/command.c.
4211 * All server commands now handle the command identifier the right
4212 way when sending the command reply to the client. The client can
4213 use to identify the command replies with the identifier.
4215 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Added silc_server_get_client_route to resolve the route to
4218 the client indicated by the client ID. Affected file is
4221 * Added silc_server_relay_packet as general function to relay
4222 packet to arbitrary destination. This deprecates functions
4223 like _send_private_message_key, _relay_notify etc. Affected
4224 file is silcd/packet_send.[ch].
4226 Removed silc_server_send_key_agreement,
4227 silc_server_send_private_message_key and
4228 silc_server_packet_relay_notify functions from the file
4229 silcd/packet_send.[ch].
4233 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4234 server. Affected file silcd/packet_receive.[ch].
4236 * Implemented the KILL command to the client. Implemented the
4237 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4238 Affected files lib/silcclient/command[_reply].c and
4239 lib/silcclient/client_notify.c. Implemented the KILL notify
4240 printing in the user inteface.
4242 * Fixed a lot silc_parse_nick memory leaks from the client
4243 library in the file lib/silcclient/command.c.
4245 * Changed the silc_server_send_notify_on_channels's `sender'
4246 argument from SilcSocketConnection to SilcClientEntry to
4247 check the sender as entry and not as connection object and not
4248 to send to the client provided as argument. The affected file
4249 is silcd/packet_send.[ch].
4251 * The notify packets that are destined directly to the client used
4252 to not to be processed by the server. Now changed that and the
4253 server processes all notify packets. After relaying the packet
4254 to the client the notify packet is processed in the server.
4256 * The silc_server_free_client_data now checks whether there is
4257 pending outgoing traffic for the client and purges the data to
4258 the network before removing the client entry.
4260 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4263 an client is killed from the SILC Network. Updated the protocol
4266 Added new function silc_server_send_notify_killed to the
4267 silcd/packet_send.[ch].
4269 * Added function silc_server_packet_relay_notify to relay notify
4270 packets that are destined directly to a client. In this case
4271 the server does not process the notify packets but merely relays
4272 it to the client. Affected file silcd/packet_send.[ch].
4274 Added also silc_server_packet_process_relay_notify to check
4275 whereto relay the notify. Affected file is
4276 silcd/packet_receive.[ch].
4278 * Implemented the KILL command to the server.
4282 * Added the backup schema desgined last fall to the protocol
4283 specs for everyone to see. The specification is in the
4284 *-spec-xx.txt draft and the packet type definitions for the
4285 backup routers is in *-pp-xx.txt draft. Thusly, added also
4286 new packet type SILC_PACKET_CELL_ROUTERS.
4288 * A big security problem in the implementation discovered. The
4289 signoff of an client did not cause new channel key generation
4290 which it of course should've done. The channel keys must be
4291 always re-generated when client leaves (or signoffs) the channel.
4292 The silc_server_remove_from_channels funtion now handles
4293 the channel key re-generation.
4295 * Added `sender' argument to the silc_server_send_notify_on_channels
4296 to not to send the client provided as argument. Affected file
4297 silcd/packet_send.[ch].
4299 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Implemented OPER and SILCOPER commands into the server and
4304 * Added silc_auth_verify and silc_auth_verify_data to verify
4305 the authentication directly from the authentication payload.
4306 It supports verifying both passphrase and public key based
4307 authentication. Affected file lib/silccore/silcauth.[ch].
4309 * Added `hash' field to the SilcIDListData structure. It is the
4310 hash negotiated in the SKE protocol. Affected file is
4313 * Slight redesigning of the SilcAuthPayload handling routines.
4314 Do not send SilcPKCS but SilcPublicKey as argument.
4316 * Implemented the public key authentication support to the
4317 serverconfig. The public key is loaded from the provided path
4318 and saved as authentication data to void * pointer. Thus,
4319 changed the unsigned char *auth_data to void *auth_data;
4321 * Fixed SHUTDOWN command to send the reply before the server
4322 is shutdown. :) Affected file silcd/command.c.
4324 * Fixed fatal bug in CONNECT command. The hostname was invalid
4325 memory and server crashed. Affected file silcd/command.c.
4327 * Fixed fatal bug in CLOSE command. The server_entry became
4328 invalid but was referenced later in the command. Affected file
4331 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Fixed fatal bug in failure packet handling. Server ignored
4334 the failure and thus crashed when it came.
4338 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4341 that the command may be executed only once in (about) 2 seconds.
4342 The old SILC_CF_LAG flag is same but allows command bursts up
4343 to five before limiting.
4345 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4346 server code. Various commands now includes the CF_LAG_STRICT
4347 flag to disallow any kind of miss-use of the command.
4349 * Fixed the silc_buffer_unformat to not to allocate any data
4350 if the length of the data is zero. It used to allocate the
4351 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4353 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * Changed the format of AdminConnection configuration section
4356 in the server. Added username of the admin to the format.
4357 Affected files silcd/serverconfig.[ch].
4359 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4360 to return admin configuration data by host, username and/or
4363 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Implemented WHOWAS command to the server. Added the functions:
4367 silc_server_command_whowas_parse,
4368 silc_server_command_whowas_send_reply,
4369 silc_server_command_whowas_from_client and
4370 silc_server_command_whowas_from_server
4372 * Added <Client ID> argument to the WHOWAS command reply. Updated
4373 the protocol specs accordingly.
4375 * Implemented WHOWAS command and command_reply to the client
4378 Implemented the WHOWAS printing on the user interface.
4380 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4382 * Added new argument to the WHOWAS command reply, the real name.
4383 It is an optional argument. Updated the protocol specs.
4385 * Added SilcIDCacheDestructor callback that is registered when
4386 the SilcIDCache is allocated. The callback is called when
4387 an cache entry in the ID Cache expires, or is purged from the
4388 cache. Added into lib/silccore/idcache.[ch].
4390 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4391 to destruct the client entries when the cache entry expires.
4392 Other ID Cache's in server and in the client library ignores
4395 * If the ID Cache entry's `expire' field is zero then the entry
4396 never expires. Added boolean `expire' argument to the
4397 silc_idcache_add function in the lib/silccore/idcache.[ch].
4398 If it is TRUE the default expiry value is used.
4400 * Added silc_server_free_client_data_timeout that is registered
4401 when client disconnects. By default for 5 minutes we preserve
4402 the client entry for history - for WHOWAS command.
4404 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Added support to the server to enforce that commands are not
4407 executed more than once in 2 seconds. If server receives
4408 commands from client more frequently, timeout is registered
4409 to process the commands. Affected file silcd/command.c.
4410 Added new function silc_server_command_process_timeout.
4412 * Changed NICK_NOTIFY handling in client library to check that
4413 if the client's nickname was changed, so there is no need to
4414 resolve anything from the server.
4416 * Removed error printing from the WHOIS and IDENTIFY commands.
4417 If error occurs then it is ignored silently in the client library.
4418 The application, however, may map the received error to
4419 human readable error string. The application currently maps
4420 the NO_SUCH_NICKNAME error to string.
4422 * Made the command status message public to the application. Moved
4423 them from lib/silcclient/command_reply.c to
4424 lib/silcclient/command_reply.h. The application can map the
4425 received command status to the string with the
4426 silc_client_command_status_message function.
4428 * Added check to the server to check that client's ID is same
4429 as the Source ID in the packet the client sent. They must
4432 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Added dist-bzip hook to the Makefile.am to make bzip2
4435 compressed distributions.
4437 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Server now enforces the maximum length for the nickname and
4440 the channel as protocol specification dictates. 128 bytes for
4441 nickname and 256 bytes for channel name.
4443 * Moved the WHOIS printing to the application. The client libary
4444 does not print out the WHOIS information anymore, the application
4445 must do it. Renamed silc_client_command_reply_whois_print to
4446 the silc_client_command_reply_whois_save.
4448 The client's idle time is also sent to the application now, and
4449 the idle is shown on screen.
4451 * Added silc_client_command_reply_identify_save to save the
4452 received IDENTIFY entries.
4454 * Do not check for channel private keys in message sending and
4455 reception if the channel does not have the PRIVKEY mode set.
4456 Affected file lib/silclient/client_channel.c.
4458 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4461 just surfaced after chaning the JOIN procedure.
4463 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4465 * Added silc_client_get_clients_by_list to get client entries
4466 from Client ID list, that is returned for example by JOIN
4467 and USERS command replies. The application should use this
4468 function for example when JOIN command reply is received to
4469 resolve the clients already on the channel (library does not
4470 do that anymore as USERS command reply is not used in the JOIN
4471 procedure anymore). Affected files lib/silcclient/silcapi.h and
4472 lib/silcclient/idlist.c.
4474 * JOIN command reply and USERS command reply returns now SilcBuffer
4475 pointers instead of unsigned char pointers when returning
4476 the client list and mode list.
4478 * Added <Client ID> argument to the JOIN command reply, mainly
4479 for the server to identify for which client the command was
4480 originally sent. Updated protocol specs accordingly.
4482 * Added SilcDlist private_key pointer to the SilcChannelEntry
4483 in the client to support the channel private keys. Affected
4484 file is lib/silcclient/idlist.h.
4486 * Added SilcChannelPrivateKey argument to the function
4487 silc_client_send_channel_message so that application can choose
4488 to use specific private ke if it wants to. If it is not provided,
4489 the normal channel key is used, unless private keys are set.
4490 In this case the first (key that was added first) is used
4491 as the encryption key.
4493 * Implemented the support for channel private key handling.
4494 Implemented the following functions:
4496 silc_client_add_channel_private_key,
4497 silc_client_del_channel_private_keys,
4498 silc_client_del_channel_private_key,
4499 silc_client_list_channel_private_keys and
4500 silc_client_free_channel_private_keys
4502 Affected file lib/silcclient/client_channel.c.
4504 * Added the support for the private keys in the channel message
4505 sending and encryption and in the message reception and
4506 decryption. Affected funtions are
4507 silc_client_send_channel_message and silc_client_channel_message.
4509 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4511 * Added SKE's key verify callback to the client library's
4512 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4514 * Removed the statement that server (or router) must send USERS
4515 command reply when joining to the channel so that the client
4516 knows who are on the channel. Instead, the client list and
4517 client's mode list is now sent in the JOIN command reply to the
4518 client who joined channel. This is better solution.
4520 * Added function silc_server_get_users_on_channel and function
4521 silc_server_save_users_on_channel to the silcd/server.[ch].
4523 * Removed function silc_server_command_send_users from the
4526 * Do not show topic on the client library anymore. The topic is
4527 sent in the command reply notify to the application and the
4528 application must show the topic now.
4530 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Added client searching by nickname hash into the IDENTIFY and
4533 WHOIS commands in the server as they were clearly missing from
4534 them. Affected file is silcd/command.c.
4536 * Fixed a bug in private message receiving in the client library.
4537 The remote ID was freed and it wasn't supposed, now it is
4540 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Minor fix to the channel payload; allocate the data area, as it
4543 needs to be of specific length.
4545 * If the key agreement port is zero then the operating
4546 system will define the bound port. Affected files are
4547 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4549 * Added new function silc_channel_payload_decrypt into the file
4550 lib/silccore/silcchannel.[ch].
4552 * Moved the channel message etc, check from silc_packet_decrypt
4553 to applications. The library calls now a generic
4554 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4555 when the packet is either normal or special. This was done to
4556 allow more wide range of checking that was not allowed when
4557 the code was in library. Now applications can do virtually any
4558 checks to the packet and return to the library the decision how
4559 the packet should be processed. Affected files are
4560 lib/silccore/silcpacket.[ch].
4562 Added silc_server_packet_decrypt_check to the server and
4563 silc_client_packet_decrypt_check to the client library.
4565 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4566 to send with specified source and destination information.
4568 * Channel message delivery between routers was broken after the
4569 channel key distribution was fixed earlier. The channel key
4570 was used be to distributed to other routers as well which is not
4571 allowed by the protocol. Now this is fixed and channel keys
4572 really are cell specific and the channel message delivery between
4573 routers comply with the protocol specification.
4575 * Fixed various commands in server to check also the global list
4576 for the channel entry and not just the local list. The affected
4577 file silcd/command.c.
4579 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Added assert()s to buffer formatting and unformatting routines
4582 to assert (if --enable-debug) when error occurs. Affected
4583 file: lib/silcutil/silcbuffmt.c.
4585 * Changed to auto-reconnect to check whether the remote host is
4586 router and register the re-connect timeout if it is. It used
4587 to check that whether we are normal server, but router must do
4588 auto-reconnect with another router as well. Affected file
4591 * Removed the [<key len>] option from CMODE command as the cipher
4592 name decides the key length, nowadays. See the defined ciphers
4593 from the protocol specification.
4595 * Added [<hmac>] option to the CMODE command to define the HMAC
4596 for the channel. Added SILC_CMODE_HMAC channel mode.
4598 * Added [<hmac>] option for the JOIN command so that user can
4599 select which HMAC is used to compute the MACs of the channel
4602 * Added Hmac field to the Channel Message Payload. The integrity
4603 of plaintext channel messages are now protected by computing
4604 MAC of the message and attaching the MAC to the payload. The
4605 MAC is encrypted. Now, it is clear that this causes some
4606 overhead to the size of the packet but rationale for this is that
4607 now the receiver can verify whether the channel message decrypted
4608 correctly and also when private keys are set for the channel the
4609 receiver can decrypt the packet with several keys and check from
4610 the MAC which key decrypted the message correctly.
4612 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4613 lib/silccrypt/silccipher.[ch].
4615 * Added silc_hash_len to return the digest length into the
4616 lib/silcrypt/silchash.[ch].
4618 * Rewrote parts of Silc Channel Payload interface in the
4619 lib/silccore/silcchannel.[ch]. The encode function now also
4620 encrypts the packet and parse function decrypts it.
4622 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Fixed a minor formatting bug in the SKE's key material processing.
4625 It actually might have processed the keys wrong way resulting
4628 * Redefined the mandatory HMAC algorithms and added new algorithms.
4629 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4630 and hmac-md5 truncated to 96 bits. The mandatory is now
4631 hmac-sha1-96. Rest are optional (including the one that used
4632 to be mandatory). Rationale for this is that the truncated HMAC
4633 length is sufficient from security point of view and can actually
4634 make the attack against the HMAC harder. Also, the truncated
4635 HMAC causes less overhead to the packets. See the RFC2104 for
4638 * Added new [hmac] configuration section. The SKE used to use
4639 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4640 is of course wrong. The official names that must be proposed in
4641 the SKE are the ones defined in the protocol specification
4642 (hmac-sha1-96 for example). The user can configure any hmac
4643 using any hash function configured in the [hash] section. At
4644 least, the mandatory must be configured.
4646 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4648 * Added HMAC list to the SKE proposal list. It has now both
4649 hash algorithm list and HMAC list. This makes the protocol
4650 incompatible with previous versions. The SKE now seems to work
4651 the way it is supposed to work, for the first time actually.
4653 * Defined plain Hash algorithms to the protocol specification.
4656 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Implemented support for key agreement packets into the server.
4659 Added functions silc_server_key_agreement and
4660 silc_server_send_key_agreement. Other than these functions,
4661 server has nothing to do with this packet.
4663 * Added support for private message key packets into the server.
4664 Added functions silc_server_private_message_key and
4665 silc_server_send_private_message_key.
4669 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4670 called in the protocol's final callback instead in the END
4671 protocol state. This makes a little more sense and in the same
4672 time in client we can use the same protocol routines for normal
4673 key exchange and to key agreement packet handling as well.
4675 * Added to both client's and server's KE protocol context the
4676 SilcSKEKeyMaterial pointer to save the key material. We will
4677 bring the key material to the protocol's final callback by doing
4678 this. The final callback must free the key material.
4680 * Added SKE's packet_send callback into client's KE protocol
4681 context so that the caller can choose what packet sending function
4682 is used. This way we can use different packet sending when
4683 doing normal SKE when doing key agreement packet handling (in
4684 the key agreement packet handling we do not want to encrypt
4687 * Implemented the responder side of the key agreement routines
4688 in the client. The client can now bind to specified port and
4689 accept incoming key negotiation. The key material is passed
4690 to the application after the protocol is over.
4692 * Implemented the processing of incoming Key Agreement packet
4693 in the client. Added function silc_client_key_agreement to
4696 * Implemented the intiator side of the key agreement routines
4697 in the client. The client can now initiate key agreement with
4698 another remote client. The key material is passed to the
4699 application after the protocol is over.
4701 * Created client_keyagr.c to include all the key agreement
4704 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4705 SILC_TASK_CALLBACK except that it is not static.
4707 * Created client_notify.c and moved the Notify packet handling
4708 from the client.[ch] into that file.
4710 * Created client_prvmsg.c and moved all private message and
4711 private message key routines from the client.[ch] into that file.
4713 * Create client_channel.c and moved all channel message and
4714 channel private key routines from the client.[ch] into that file.
4716 * Changed silc_client_get_client_by_id_resolve to resolve with
4717 WHOIS command instead of IDENTIFY command, in the file
4718 lib/silclient/idlist.c.
4720 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4722 * Implemented the SKE's responder side to the Client library.
4724 * When FAILURE is received to the protocol do not trust it
4725 blindly. Register a timeout to wait whether the remote closes
4726 the connection as it should do it, only after that process the
4727 actual failure. This was changed to both client and server.
4729 * Added client_internal.h to include some of the structures
4730 there instead of client.h in lib/silcclient/.
4732 * Added function silc_task_unregister_by_callback to unregister
4733 timeouts by the callback function.
4735 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Some "Incomplete WHOIS info" errors has been appearing on the
4738 log files. Took away the entry->userinfo check from WHOIS
4739 reply sending. The entry->userinfo is now " " if client did not
4740 provide one. I thought this was fixed earlier but something
4741 is wrong still. Let's see if the error still appears.
4743 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * Fixed a minor bug in the login when the channel key is
4746 re-generated in the server. It used to generate the key in
4747 wrong order and thus caused problems in the channel traffic.
4749 * Fixed a minor bug in channel key distsribution after
4750 KICK command. The key was not sent to the router even though
4753 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Added silc_ske_process_key_material_data as generic routine
4756 to process any key material as the SILC protocol dictates. The
4757 function is used by the actual SKE library but can be used by
4758 applications as well. This relates to the private message keys
4759 and the channel private keys since they must be processed the
4760 same way the normal SILC session keys. The protocol dictates
4761 this. Affected files: lib/silcske/silcske.[ch].
4763 Added also silc_ske_free_key_material to free the
4764 SilcSKEKeyMaterial structure.
4766 * Defined silc_cipher_set_key function to set the key for
4767 cipher without using the object's method function. The affected
4768 files: lib/silccrypt/silccipher.[ch].
4770 * Implemented silc silc_client_add_private_message_key,
4771 silc_client_add_private_message_key_ske,
4772 silc_client_del_private_message_key,
4773 silc_client_list_private_message_keys and
4774 silc_client_free_private_message_keys functions in the
4777 Added functions silc_client_send_private_message_key to send
4778 the Private Message Key payload and silc_client_private_message_key
4779 to handle incoming Private Message Key payload.
4781 * Added Cipher field to the Private Message Key payload to set
4782 the cipher to be used. If ignored, the default cipher defined
4783 in the SILC protocol (aes-256-cbc) is used.
4785 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * Removed lib/silcclient/ops.h file.
4789 Redefined parts of the SILC Client Library API. Created new
4790 file silcapi.h that deprecates the ops.h file and defines the
4791 published Client Library API. Defined also private message key
4792 API and channel private key API into the file.
4794 This is the file that the application must include from the
4795 SILC Client Library. Other files need not be included by
4796 the application anymore.
4798 * Added new key_agreement client operation callback and also
4799 defined the Key Agreement library API for the application.
4801 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4803 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4804 is used by clients to request key negotiation between another
4805 client in the SILC network. If the negotiation is started it
4806 is performed using the SKE protocol. The result of the
4807 negotiation, the secret key material, can be used for example
4808 as private message key.
4810 Implemented the Key Agreement payload into the files
4811 lib/silccore/silauth.[ch].
4813 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Redefined ciphers for the SILC protocol. Added some new ciphers
4816 and defined the key lengths for the algorithms. Changed the
4817 code accordingly. The default key length is now 256 bits.
4819 * Fixed SKE key distribution function silc_ske_process_key_material
4820 when the key length is more than 128 bits. The default key
4821 length in SILC is now 256 bits.
4823 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4824 to indicate unsupported algorithm.
4826 * Renamed rijndael.c to aes.c and all functions as well.
4828 * Fixed a long standing channel key setting bug in client library.
4829 Weird that it has never surfaced before.
4831 * Fixed bug in channel deletion. If the entire channel is removed
4832 then it must also delete the references of the channel entry
4833 from the client's channel list as the client's channel entry and
4834 the channel's client entry share same memory.
4836 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Implemented CONNECT and SHUTDOWN commands in the client.
4840 * Implemented CLOSE command to the client.
4842 * Added the function silc_idlist_find_server_by_name into the
4843 files silcd/idlist.[ch].
4845 Added the function silc_idlist_find_server_by_conn into the
4846 files silcd/idlist.[ch].
4848 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * DIE command was renamed to SHUTDOWN. Updated the both code
4853 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4854 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4856 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4859 * Added function silc_server_create_connection function to create
4860 connection to remote router. My server implementation actually
4861 does not allow router to connect to normal server (it expects
4862 that normal server always initiates the connection to the router)
4863 so the CONNECT command is only good for connecting to another
4866 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4869 or some other client was kicked from the channel.
4871 Implemented the handling of the notify type to both client
4874 Implemented silc_server_send_notify_kicked to send the KICKED
4875 notify. It is used to send it to the server's primary router.
4877 * Implemented the KICK command into server and client.
4879 * Added `query' argument to the silc_idlist_get_client function
4880 to indicate whether to query the client from server or not if
4883 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4884 to indicate that the client is not channel founder.
4888 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Removed the rng context from SilcPacketContext structure and
4891 changed that the packet routine uses the Global RNG API.
4893 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Added support for quit message that client can "leave" on the
4896 channel when it quits the SILC. It is ditributed inside the
4897 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4899 Added silc_server_free_client_data that will take the
4900 signoff message as argument.
4902 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4904 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4906 * Updated parts of the protocol specification to keep it up
4909 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4912 payloads in one packet.
4914 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4915 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4916 use now the new List flag.
4918 * Also deprecated the following packet types: REPLACE_ID,
4919 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4921 * Added list support for Notify packet in server.
4923 * Added silc_server_send_notify_channel_change to send the
4924 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4925 the silc_server_send_replace_id.
4927 * Added silc_server_send_notify_nick_change to send the
4928 NICK_CHANGE notify type. Deprecates the function
4929 silc_server_send_replace_id.
4931 * Added silc_server_send_notify_join to send the JOIN notify type.
4932 Deprecates the function silc_server_send_new_channel_user.
4934 * Added silc_server_send_notify_leave to send LEAVE notify type.
4935 Deprecates the function silc_server_send_remove_channel_user.
4937 * Added silc_server_send_notify_cmode and
4938 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4939 types. Deprecates the silc_server_send_set_mode function.
4941 * Added SERVER_SIGNOFF notify type to indicate that server has
4942 quit. This means that all clients on the channel from that
4943 server will drop. This can be also used when netsplit happens.
4945 Deprecated REMOVE_ID packet type since it is not needed anymore
4948 Added silc_server_send_notify_server_signoff to send the
4949 SERVER_SIGNOFF notify type. Deprecates the function
4950 silc_server_send_remove_id.
4952 Added also silc_server_send_notify_signoff to send the
4953 SIGNOFF notify type.
4955 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4956 SILC protocol from this day on. Changed the protocol
4957 specification as well.
4959 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4960 notify type. It is used between routers to notify about
4961 topic changes on a channel.
4963 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4966 * Partly updated the protocol specification to comply with the
4967 changes now made. It is still though a bit outdated.
4969 * The JOIN notify type now takes one extra argument <Channel ID>.
4970 The packet used to be destined to the channel but now the
4971 JOIN type may be sent as list thus it is impossible to
4972 destine it to any specific channel. By adding this argument
4973 it is again possible.
4975 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * Added CREDITS file. The CHANGES and CREDITS file will appear
4978 in the distribution as well.
4980 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4983 types in the server's silcd/packet_receive.c.
4985 * Implemented CMODE and CUMODE to work in router environment.
4987 * Fixed minor encoding and decoding buglet from the
4988 lib/silccore/silcmode.c.
4990 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4993 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4995 * Changed all SilcConfigServer* and silc_config_server* to
4996 SilcServerConfig* and silc_server_config*, respectively.
4999 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Associated the ID (client or server ID) to the Authentication
5002 Payload to avoid any possibility of forging. Updated the
5003 protocol specification and the code accordingly.
5005 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * The RSA key length is now save to the RsaKey context in the
5008 key generation process in lib/silccrypt/rsa.c. The key length
5009 is now used to figure out the maximum size of the block allowed
5010 to be encrypted/signed.
5012 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5013 is equivalent to the silc_mp_mp2bin but does not allocate any
5016 * Changed silc_mp_mp2bin API to take length argument. If it is
5017 non-zero then the buffer is allocated that large. If zero, then
5018 the size is approximated using silc_mp_sizeinbase, which however
5021 * Created Global RNG API which is global RNG that application can
5022 initialize. After initializing, any routine anywhere in the
5023 code (including library) can use RNG without allocating a new
5024 RNG object. This was done to allow this sort of use of the
5025 RNG in code that has no chance to allocate RNG object. All
5026 applications currently allocate this and many routines in the
5027 library use this. Affected file lib/silccrypt/silcrng.[ch].
5029 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5030 it to use the Global RNG API.
5032 * Defined Authentication Payload into protocol specification that
5033 is used during SILC session to authenticate entities. It is
5034 used for example by client to authenticate itself to the server
5035 to obtain server operator privileges.
5037 Implemented this payload into the lib/silccore/silcauth.[ch].
5038 Implemented also routines for public key based authentication
5039 as the new protocol specification dictates.
5041 Moved definitions of different authentication methods from
5042 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5044 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5045 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5046 silc_pkcs_verify_with_hash functions into the file
5047 lib/silccrypt/silcpkcs.[ch].
5049 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * The client entry's userinfo pointer must be always valid.
5052 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5053 will fail since it requires the userinfo. Now, the userinfo
5054 is allocated as "" if actual userinfo does not exist. Actually,
5055 it must exist and it is totally Ok to drop client connections
5056 that does not announce the userinfo. However, we will make
5057 this workaround for now.
5059 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5060 to return the remote port by socket.
5062 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5065 SILC_SERVER_PENDING_EXEC and added an new macro
5066 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5067 data or when error occurs while processing the pending command.
5069 Added new argument `destructor' into silc_server_command_pending
5070 and to the SilcServerCommandPending object. This destructor is
5071 now called after calling the pending callback or if error occurs
5072 immediately. If error occurs the actual pending callback won't
5073 be called at all - only the destructor. The destructor may be
5074 NULL if destructor is not needed.
5076 All this applies for client library code as well. Similar
5077 changes were made there as well for the pending commands.
5079 In the client, the application must now allocate the
5080 SilcClientCommandContext with the silc_client_command_alloc
5083 * Added reference counter to the SilcServerCommandContext. Added
5084 function silc_server_command_alloc and silc_server_command_dup
5087 Same type of functions added to the client library for the same
5090 * Removed the cmd_ident from IDListData away since it is now
5091 global for all connections. It is the command identifier used
5092 in command sending and with pending commands. The affected file
5095 * Added reference counter to the SilcSocketConnection objecet to
5096 indicate the usage count of the object. The object won't be
5097 freed untill the reference counter hits zero. Currently only
5098 server uses this, and client ignores it. The client must be
5099 set to use this too later. The affected files are
5100 lib/silccore/silcsockconn.[ch]. Added also the function
5101 silc_socket_dup to increase the reference counter.
5103 This was mainly added because it is possible that the socket
5104 is removed underneath of pending command or other async
5105 operation. Now it won't be free'd and proper DISCONNECTING
5106 flags, etc. can be set to avoid sending data to connection that
5107 is not valid anymore.
5109 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5110 the connection. After that it sets SILC_SET_DISCONNECTED.
5111 It is, however, possible that the socket data is not still freed.
5112 The silc_server_packet_process now checks that data is not
5113 read or written to connection that is DISCONNECTED. The socket
5114 get's freed when the reference counter hits zero.
5116 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * Changed the client operation API: channel_message operation's
5119 `sender' is now the client entry of the sender, not the nickname
5120 and the `channel' is the channel entry, not the channel name.
5122 In the private_message operation the `sender' is now also the
5123 client entry of the sender not the nickname.
5125 Affected file is lib/silcclient/ops.h and all applications
5126 using the client operations.
5128 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5130 * Moved the calling of ops->connect() from connect_to_server_final
5131 into receive_new_id functin since that is the point when the
5132 client is actually allowed to send traffic to network. The
5133 affected file is lib/silcclient/client.c.
5135 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5138 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5139 (if needs broadcasting) instead of broadcasting the packets one
5140 by one which would make a burst in the network traffic.
5142 * Added `broadcast' argument to the functions in silcd/server.[ch]
5143 silc_server_create_new_channel[_with_id] to indicate whether
5144 to send New Channel packet to primary router.
5146 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Added new function into the silcd/server.[ch] files:
5149 silc_server_create_new_channel_with_id to create new channel with
5150 already existing Channel ID.
5152 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5153 lib/silccore/silcpacket.h. This packet is used t send list of
5154 Set Mode payloads inside one packet. Server uses this to set
5155 the modes for the channels and clients on those channels, that it
5156 announced to the router when it connected to it. The protocol
5157 specification has been updated accordingly.
5159 * The silc_server_new_channel did not handle the packet coming
5160 from normal server as it normally does not send that. However,
5161 when it announces its channels it does send it. Implemented
5162 the support for that.
5164 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5165 into the file lib/silccore/id.h.
5167 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Fixed memory leaks in the functions silc_idlist_del_client,
5170 silc_idlist_del_channel and silc_idlist_del_server in the file
5171 silcd/idlist.c. All of those leaked like a sieve.
5173 * Fixed some small memory leaks in the client's function
5174 silc_client_notify_by_server.
5176 * Added functions into silcd/server.c: silc_server_announce_clients,
5177 silc_server_announce_channels and silc_server_announce_server.
5178 These functions are used by normal and router server to announce
5179 to its primary router about clients, channels and servers (when
5180 router) that we own. This is done after we've connected to the
5183 These functions effectively implements the following packet types:
5184 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5185 and SILC_PACKET_NEW_ID_LIST.
5187 * Added new functions into the silcd/packet_receive.[ch]:
5188 silc_server_new_id_list, silc_server_new_channel_list and
5189 silc_server_new_channel_user_list to handle the incoming
5190 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5192 * Added support of changing Channel ID in the function
5193 silc_server_replace_id. If the server that announces a channel
5194 to the router already exists in the router (with same name but
5195 with different Channel ID), router is responsible to send
5196 Replace ID packet to the server and force the server to change
5197 the Channel ID to the one router has.
5199 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5200 client that the Channel ID has been changed by the router. The
5201 normal server sends this to the client. Client must start using
5202 the new Channel ID as the channel's ID.
5204 Implemented handling of this new type into lib/silcclient/client.c
5205 into the function silc_client_notify_by_server.
5207 * Added new function silc_idlist_replace_channel_id into the files
5208 silcd/idlist.[ch] to replace the Channel ID.
5210 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Call silc_server_command_identify_check always when processing
5213 the IDENTIFY command in silcd/command.c
5215 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5218 send keepalive packets. The packet can be sent by clients,
5219 servers and routers.
5221 Added function silc_socket_set_heartbeat into the file
5222 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5223 If not set, the heartbeat is not performed. The actual
5224 heartbeat is implemented in the low level socket connection
5225 library. However, application is responsible of actually
5228 Added silc_server_send_heartbeat to send the actual heartbeat
5229 packet into silcd/packet_send.[ch]. Server now performs
5230 keepalive with all connections.
5232 * Added silc_task_get_first function into lib/silcutil/silctask.c
5233 to return the timeout task with shortest timeout. There was a bug
5234 in task unregistration that caused problems. TODO has been
5235 updated to include that task system must be rewritten.
5237 * The client library will now resolve the client information when
5238 receiving JOIN notify from server for client that we know but
5239 have incomplete information.
5241 * Rewrote parts of silc_server_remove_from_channels and
5242 silc_server_remove_from_one_channel as they did not remove the
5243 channel in some circumstances even though they should've.
5245 * Encryption problem encountered in server:
5247 The LEAVE command used to send the Channel Key packet to the
5248 router immediately after generating it. However, the code
5249 had earlier sent Remove Channel user packet but not immediately,
5250 ie. it was put to queue. The order of packets in the router
5251 was that Channel Key packet was first and Remove Channel User
5252 packet was second, even though they were encrypted in the
5253 reverse order. For this reason, MAC check failed. Now, this
5254 is fixed by not sending the Channel Key packet immediately but
5255 putting it to queue. However, this is more fundamental problem:
5256 packets that are in queue should actually not be encrypted
5257 because packets that are sent immediately gets encrypted
5258 actually with wrong IV (and thus MAC check fails). So, packets
5259 that are in queue should be encrypted when they are sent to
5260 the wire and not when they put to the queue.
5262 However, the problem is that the current system has not been
5263 designed to work that way. Instead, the packet is encrypted
5264 as soon as possible and left to the queue. The queue is then
5265 just purged into wire. There won't be any fixes for this
5266 any time soon. So, the current semantic for packet sending
5269 o If you send packet to remote host and do not force the send
5270 (the packet will be in queue) then all subsequent packets to the
5271 same remote host must also be put to the queue. Only after the
5272 queue has been purged is it safe again to force the packet
5275 o If you send all packets immediately then it safe to send
5276 any of subsequent packets through the queue, however, after
5277 the first packet is put to queue then any subsequent packets
5278 must also be put to the queue.
5280 Follow these rules and everything works fine.
5282 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Added new function silc_server_remove_clients_by_server to
5285 remove all client entries from ID list when the server connection
5286 is lost. In this case it is also important to invalidate all
5287 client entires as they hold the invalid server entry. This
5288 fixes fatal bug when server has lost connection and will reconnect
5291 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Made some sanity checks to silc_server_daemonise like to check
5294 whether the requested user and group actually exists.
5296 * Added sanity check to SKE's silc_ske_responder_finish to check
5297 that the public and private key actually is valid.
5299 * Invalidate the client's nickname when receiving Replace ID
5300 packet and the Client ID is being replaced. This means that the
5301 server will query the nickname if someone needs it (client)
5304 * Sort the ID Cache in client library when the ID Cache data
5305 has changed (needs sorting).
5307 * Do not allow for SILC client to create several connections to
5308 several servers. The client does not support windows right now
5309 and generating multiple connections causes weird behaviour.
5311 Irssi-silc client does support windows and can handle several
5312 connections without problems, see: www.irssi.org and SILC plugin.
5314 * Fixed some places where client was added to the IDList. The
5315 rule of thumb is following (in order to get everything right):
5316 If the client is directly connected local client then the
5317 `connection' argument must be set and `router' argument must be
5318 NULL to silc_idlist_add_client function. If the client is not
5319 directly connected client then the `router' argument must
5320 bet set and the `connection' argument must be NULL to the
5321 silc_idlist_add_client function.
5323 * The funtion silc_server_packet_send_local_channel actually did
5324 not check whether the client was locally connected or not. It
5325 does that now. Fixed a bug related to LEAVE command.
5327 * Fixed Remove Channel User payload parsing bug in server's
5328 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5330 * The server's silc_server_save_channel_key now checks also the
5331 global ID list for the channel as it might not be in the local
5332 list. Fixed a bug related to LEAVE command.
5334 * Is this the end of the [<unknown>] buglet that has been lurking
5335 around for a long time? A little for loop fix in server's
5336 silc_server_command_whois_parse that is used by both IDENTIFY
5337 and WHOIS command. At least, this was a clear bug and a cause
5338 of one type of [<unknown>] buglet.
5340 * WHOIS and IDENTIFY commands call the function
5341 silc_server_command_[whois/identify]_check function even if
5342 we are not router server.
5344 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Added --with-gmp configuration option. If set the GMP
5347 is always compiled in the SILC source tree. If not set then
5348 it is checked whether the system has the GMP3 installed. If
5349 it has then the GMP won't be compiled (the system's headers
5350 and library is used), if it doesn't have it then the GMP is
5351 compiled in the SILC source tree.
5353 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Changed RSA private exponent generation to what PKCS #1
5356 suggests. We try to find the smallest possible d by doing
5357 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5358 not security fix but optimization.
5360 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5362 * Added new config entry [Identity] to fork the server and run
5363 it as specific user and group. A patch from Bostik.
5365 * Imported Dotconf configuration library into lib/dotconf.
5366 This will be used to create the SILC configuration files later.
5367 It will appear in the distsribution after this commit.
5369 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * A big code auditing weekend happening. Auditing code for
5372 obvious mistakes, bugs and errors. Also, removing any code
5375 Removed files for being obsolete:
5377 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5378 inline in the file lib/silcutil/silcbuffer.h)
5380 o lib/silcutil/silcbufutil.c (the header has inline versions)
5382 Changed code to fix possible error conditions:
5384 o The buffer formatting routines now check that the destination
5385 buffer really has enough space to add the data. This applies for
5386 both buffer formatting and unformatting
5387 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5388 unformatting was changed to accomodate following rules:
5389 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5390 sent to the function while XXX_*STRING will not allocate or copy
5391 the data into the buffer. Instead it sets the pointer from the
5392 buffer into the pointer sent as argument (XXX_*STRING used to
5393 require that the pointer must be allocated already). This change
5394 makes this whole thing a bit more consistent and more optimized
5395 (note that the data returned in the unformatting with XXX_*STRING
5396 must not be freed now). The routines return now -1 on error.
5398 o Tried to find all code that use buffer_format and buffer_unformat
5399 and added return value checking to prevent formatting and
5400 especially unformatting errors and possible subsequent fatal
5403 o Changed ske->x and ske->KEY to mallocated pointers in
5404 lib/silcske/silcske.h. Fixed possible data and memory leak.
5406 o Added return value checking to all *_parse* functions. Fixed
5407 many memory leaks as well.
5409 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5410 so that buffer overflows would not happen. All code now also
5411 checks the return value as it can fail.
5413 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Added reconnection support to server if the normal server looses
5416 its connection to the router (for example if router is rebooted).
5417 The server performs normal reconnection strategy implemented
5418 to the server. Affected file silcd/server.c.
5420 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Added new packet type SILC_PACKET_SET_MODE that is used to
5423 distribute the information about changed modes (for clients,
5424 channels and clients channel modes) to all routers in the
5425 network. Updated the protocol specification accordingly.
5427 Added functions into silcd/packet_send.c and
5428 silcd/packet_receive.c: silc_server_send_set_mode,
5429 silc_server_set_mode.
5431 Added new files silcmode.[ch] into lib/silccore that implements
5432 the encoding and decoding of Set Mode Payload. Added new type
5433 SilcSetModePayload. Moved the definitions of different modes
5434 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5436 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5438 * Oops, a little mistake in server's connection authentication
5439 protocol. The protocol is not ended with FAILURE but with
5440 SUCCESS if the authentication is Ok. :) Affected file is
5443 * Implemented NICK_CHANGE notify handling in server in the file
5444 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5445 the local clients on the channel. After the changing nickname
5446 in router environment snhould work and the [<unknown>] nickname
5447 should appear no more.
5449 The silc_server_replace_id function that receives the Replace ID
5450 payload now sends the NICK_CHANGE notify type also in the file
5451 silcd/packet_receive.c
5453 * Changed WHOIS and IDENTIFY command to support the maximum amount
5454 of arguments defined in protocol specs (3328 arguments). This
5455 fixed a bug that caused problems when there were more than three
5458 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Added extra parameter, command identifier, to the
5461 silc_client_send_command so that explicit command identifier
5464 Changed that ID list routines uses specific command identifier
5465 when sending WHOIS/IDENTIFY requests to the server so that they
5466 can be identified when the reply comes back.
5468 Affected files lib/silcclient/command.[ch],
5469 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5471 * Added `sender' argument to silc_server_packet_send_to_channel
5472 to indicaet the sender who originally sent the packet to us
5473 that we are now re-sending. Ignored if NULL. Affected file
5474 silcd/packet_send.[ch].
5476 * Added some server statistics support in silcd/server_internal.h
5477 SilcServerStatistics structure and around the server code. Also
5478 send some nice statistics information when client is connecting
5481 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Fixed channel ID decoding in server's JOIN command reply in
5484 silcd/command_reply.c
5486 * Fixed braodcasting of replace ID payload to not to send it if
5487 we are standalone server in silcd/packet_receive.c.
5489 * Fixed all channel message sending routines to not to send
5490 packets to clients that has router set, since they are routed
5491 separately in the same function earlier. Affects file
5492 silcd/packet_send.c and all channel packet sending functions.
5494 * In USERS reply, res_argv[i] are not allocated, the table
5495 is allocated. Thus changed that free the table, not its
5498 * In server's whois_check and identify_check if the client is
5499 locally connected do not send any WHOIS commands - they are not
5502 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5504 * Fixed some minor bugs in client when sending WHOIS command. The
5505 arguments was in wrong order.
5507 * Removed statis function add_to_channel from server in
5508 silcd/command.c that was previously used with the joining but
5511 * Tested USERS command in router environment successfully with two
5512 routers, two servers and two clients.
5514 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Reorganized the USERS command and command reply in client library
5517 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5518 When the command is given by user we register a pending command
5519 callback that will reprocess the command after the reply has been
5520 received from the server. When reprocessing the packet we then
5521 display the information. Thus, the USERS information is displayed
5522 now in the command callback instead of in the command reply
5523 callback. The processing of the command is same as previously
5524 when server has sent the command reply in the JOINing process.
5526 * Added to USERS command in silcd/command_reply.c to join the client,
5527 we didn't use to know about, to the channel after we've created
5528 a client entry for it. Also, for clienet we did know already still
5529 check whether it is on the channel or not and add it if not.
5531 * Removed silc_server_command_join_notify as the function and its
5534 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Changed the client's pending command handling to the same as the
5537 server's pending command handling. It is also now possible to
5538 execute command reply functions from other command reply
5539 function as the function callbacks for commands and command
5540 replies are one and same. The pending commands are not static
5541 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5542 in client connection context. Thus, pending commands are server
5543 connection specific as it is convenient.
5545 Changed the function silc_client_command_pending and
5546 silc_client_command_pending_del and added new function
5547 silc_client_command_pending_check. Removed the
5548 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5551 * Added cmd_ident, current command identifier, to the client
5552 connection context in lib/silcclient/client.h to keep track on
5553 command identifiers used in command sending. Client's command reply
5554 function handling now supports the mandatory command identifiers.
5556 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5557 funtions in client to fully support pending command callbacks.
5559 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5560 as one of the arguments to the application in the command reply
5563 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5564 before first releasing SILC but came back. Now it is removed again
5565 and should come back nomore. The FORWARDED flag was used only
5566 by the JOINing procedure by forwarding the command packet to router.
5567 Now, the JOINing procedure has been changed to more generic (due
5568 to various router environment issues) and FORWARDED is not needed
5569 anymore for anything. The protocol specification is yet to be
5572 Now, removed silc_server_packet_forward from server and the flag
5573 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5575 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5577 * Renamed NAMES command to USERS command. The NAMES was named that
5578 due to historical reasons. Now it is renamed. Also, rewrote
5579 parts of the USERS command. The nickname list is not sent anymore
5580 by the server. Only Client ID and mode lists are sent in the USERS
5581 command. Changed this also to the protocol specification.
5583 The client now resolves the names and stuff after it receives
5584 the USERS list from the server when joining to the channel.
5586 * WHOIS and IDENTIFY commands has been changed to support multiple
5587 Client ID's per command. One can now search for multiple users
5588 in the network by sending only one WHOIS or IDENTIFY command.
5589 Changed the code and the protocol specifications.
5591 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5592 uses silc_server_command_whois_parse to parse the request. */
5594 * If normal server, do not parse the WHOIS and IDENTIFY requests
5595 before sending it to the router. Saves some time.
5597 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * Fixed JOIN command on client library. Wrong number of arguments
5600 used to crash the client.
5602 * Added silc_server_channel_has_global function to check whether
5603 channel has global users or not.
5605 * Added silc_server_channel_has_local function to check whether channel
5606 has locally connected clients on the channel.
5608 * The silc_server_remove_from_one_channel now checks whether the
5609 channel has global users or not after given client was removed from
5610 the channel. It also checks whether the channel has local clients
5611 on the channel anymore. If it does not have then the channel entry
5612 is removed as it is not needed anymore.
5614 * The silc_server_notify now checks on JOIN notify whether the joining
5615 client is one of locally connected or global. If it is global then
5616 the channel has now global users on the channel and that is marked
5617 to the channel entry. Also, it now saves the global client to
5618 global list who is joining and JOINs it to the channel. This is
5619 for normal server, that is.
5621 Changed silc_server_send_notify_on_channel,
5622 silc_server_packet_relay_to_channel and
5623 silc_server_packet_send_to_channel check if we are normal server
5624 and client has router set (ie. global client) do not send the
5625 message to that client, as it is already routed to our router.
5627 * Implemented LEAVE notify type handling in silc_server_notify
5630 * Tested LEAVE command in router environment successfully. Tested
5631 with two routers, two servers and two clients.
5635 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5637 * Implemented SIGNOFF notify type handling in silc_server_notify
5640 * silc_server_remove_id now removes the client entry from all channels
5641 it has joined and thusly sends SIGNOFF notify type.
5643 * Rewrote the NAMES list generation in server by removing two excess
5644 loops. The lists are created now inside one loop.
5646 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * silc_server_remove_channel_user checks now also global list
5649 for channel and client.
5651 * silc_server_new_channel_user checks now both local and global
5652 list for channel and client. Fixed a bug in client id decoding.
5653 Used to decode wrong buffer.
5655 * silc_server_channel_message checks now both local and global
5656 list for channel entry.
5658 * Tested channel joining (hence JOIN) in router environment
5659 successfully. Tested with two routers, two servers and two
5662 * Tested channel message sending in router environment successfully.
5664 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5666 * Added silc_server_save_channel_key into server.[ch] to save the
5667 received channel key in Channel Key payload processing. It is
5668 also used in JOIN command reply handling.
5670 Equivalent function silc_client_save_channel_key added into
5671 client.[ch] into client library.
5673 * Changed JOIN command reply to send information whether the channel
5674 was created or not (is existing already) and the channel key
5675 payload. Changed protocol specs accordingly.
5677 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5678 the request was sent by ID and not by nickname. Crashed on
5681 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5683 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5684 now correctly save the received data.
5686 * silc_server_free_sock_user_data now notifies routers in the
5687 network about entities leaving the network.
5689 At the same time implemented functions silc_server_remove_id
5690 and silc_server_send_remove_id to receive and send REMOVE_ID
5691 packets. The packet is used to notify routers in the network
5692 about leaving entities. The ID removed will become invalid in
5695 * Added function silc_idlist_del_server into server. Removes and
5696 free's server entry from ID list.
5698 * silc_server_private_message function now checks, if we are router,
5699 that the destination ID really is valid ID, naturally.
5701 * In router when NEW_ID packet is received (for new client) the
5702 hash of the Client ID is saved in the ID Cache but the
5703 client->nickname is set to NULL, instead of putting the hash
5706 IDENTIFY command now also checks that client->nickname must be
5707 valid. If it is not if will request the data from the server who
5708 owns the client. Added new function
5709 silc_server_command_identify_check.
5711 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5712 to set the command to already allocated Command Payload.
5714 * Tested private message sending in router environment with two
5715 routers, two servers and two clients. Fixed minor bugs and now
5718 * Fixed segfault from client's NAMES command. Used to crash if
5721 * Forwarded packets must not be routed even if it is not destined
5722 to the receiver. Changed server code comply with this.
5724 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Added `require_reverse_mapping' boolean value to ServerParams
5727 structure. If TRUE (not default) the server will require that
5728 the connecting host has fully qualified domain name.
5730 If the reverse mapping is not required and hostname could not be
5731 found the IP address is used as hostname.
5733 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * Implemented version string checking to both client and server.
5736 The check is incomplete currently due to the abnormal version
5737 strings used in development version of SILC.
5739 * Changed all command functions in server to use the new
5742 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Changed char *data to unsigned char *data in ID Cache system to
5745 support binary data as ID Cache data. Changed code to support
5746 binary data in lib/silccore/idcache.c.
5748 * Renamed silc_server_packet_relay_command_reply to
5749 silc_server_command_reply as it is normal packet receiving
5750 function. Rewrote the function to accept command replys for
5751 servers and not only for clients.
5753 * Mark remote router always as registered server if we are connecting
5754 to it. Otherwise, commands sent by the router to us are ignored.
5756 * All ID List find routines now returns the ID Cache Entry pointer
5757 as well if requested.
5759 * WHOIS command works now in router environment, tested with two
5760 routers, two servers and two clients.
5762 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5763 in router environment (as it is almost equivalent to WHOIS) but
5764 hasn't been tested thoroughly. Added new functions:
5766 silc_server_command_identify_parse
5767 silc_server_command_identify_send_reply
5768 silc_server_command_identify_from_client
5769 silc_server_command_identify_from_server
5771 * Disabled route cache adding because adding two different ID's with
5772 same IP replaces the old cache entry thus giving wrong route.
5773 The entry->router->connection is always the fastest route anyway
5774 so route cache may not be needed. Of course, new routes maybe
5775 established after receiving the ID when the entry->router->connection
5776 might not be anymore the most optimal.
5778 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5780 * Add route cache for received ID for fast routing.
5782 * Added silc_server_packet_route to route received packet on router
5783 that is not destined to us.
5785 * Renamed silc_server_get_route to silc_server_route_get.
5787 * Added id_string and id_string_len fields into SilcServer to
5788 include encoded ServerID for fast comparing without excess
5789 encoding of the ID's.
5791 * Cleaned up WHOIS command on server side. Added following static
5794 silc_server_command_whois_parse
5795 silc_server_command_whois_check
5796 silc_server_command_whois_send_reply
5797 silc_server_command_whois_from_client
5798 silc_server_command_whois_from_server
5800 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5801 arguments in command replies. All command functions should be
5802 updated to use this macro.
5804 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Minor typo fixes on command reply handling on server.
5808 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5810 * Added silc_server_command_add_to_channel internal routine to add
5811 the client to the channel after router has created the channel and
5812 sent command reply to the server.
5814 * Added generic silc_server_send_command to send any command from
5817 * Use static buffer with ID rendering instead of duplicating data.
5819 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Fixed a channel user mode bug when joining to a channel server gave
5822 everybody channel founder rights, oops.
5824 * We mark ourselves as the router of the incoming server connection
5825 if we are router ourselves. This way we can check in some packet
5826 sending functions whether it is locally connected server. For
5827 incoming router connections we put NULL.
5829 * For router sending packets locally means now always sending the
5830 packet cell wide; to local clients and local servers. For normal
5831 server sending packet locally means sending it to only local
5834 * Fixed the JOIN command to really work in router environment. If the
5835 channel is created it is always created by the router. Router is
5836 also responsible of making the initial joining to the channel,
5837 sending JOIN notify to the sending server and distributing
5838 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5839 does not exist server doesn't do anything else but forward the
5840 command to the router which performs everything.
5842 * Added silc_server_send_channel_key function to send the Channel Key
5845 * Added silc_server_create_channel_key to create new channel key. The
5846 channel key is now re-generated everytime someone joins or leaves
5847 a channel, as protocol dictates. Note: channel->key_len is the
5850 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5853 packet_receive.[ch] to separate packet sending and receiving
5854 routines. The server.[ch] now includes everything else including
5855 actual packet processing (writing and reading data) and other
5858 Renamed silc_server_private_message_send_internal to
5859 silc_server_send_private_message. The routine is still though
5860 used only to relay private messages as server does not send
5861 private messages itself.
5863 Renamed silc_server_new_channel to silc_server_create_new_channel
5864 and added new function sicl_server_new_channel that handles the
5865 incoming New Channel packet. Added also new sending function
5866 silc_server_send_new_channel to send New Channel Payload.
5868 * Added new function silc_server_notify to process incoming notify
5869 packet to the server/router. Server may then relay the notify
5870 to clients if needed.
5872 * Added new function silc_server_new_channel_user to process incoming
5873 New Channel User packet. Router will redistribute the packet and
5874 send JOIN notify to its local clients and locally connected servers
5875 if needed. Normal server will send JOIN notify to its local client
5876 on same channel when received this packet. Added also corresponding
5877 sending function silc_server_send_new_channel_user to sent the
5880 * Added boolean route argument to send_notif_to_channel and
5881 packet_send_to_channel functions to attempt to route the packet
5882 if it is TRUE and send only locally if it is FALSE.
5884 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * silc_server_replace_id now broadcasts the received replace ID
5887 packet if it is not broadcast packet already. The router must
5888 broadcast to inform other routers about changed ID.
5890 * Added backpointer to server's router into SilcServer context in
5891 silcd/server_internal.h.
5893 * Fixed silc_server_packet_broadcast to send correct broadcast
5896 * The channel key is now distributed to the local client as soon
5897 as it is received from the router (in router environment) so that
5898 no other packet may be sent for the channel until client has
5901 * silc_server_remove_channel_user now broadcasts the received
5902 Remove Channel User packet if it is not broadcast packet already.
5903 The router must broadcast to inform other routers about removed
5906 * Added users field into SilcPacketContext that is a reference count
5907 of the context. One can increase the reference count by calling
5908 silc_packet_context_dup which is now changed to just increase the
5909 reference count instead of duplicating the data. The reference
5910 count is decresed by calling silc_packet_context_free that will
5911 free the data after the reference count hits zero.
5913 For now on the packet context and everything allocated into it
5914 (including the raw packet from network) must be freed by calling
5915 the new silc_packet_context_free function. Added also new function
5916 silc_packet_context_alloc that must be used now to allocate the
5917 context. This also means that if a routine is asynchronous from
5918 silc_[client/server]_packet_parse_type the packet context must
5919 be duplicated by calling silc_packet_context_dup. Otherwise it
5920 gets free'd after silc_[client/server]_packet_parse_type returns.
5921 Also, one must remember that if packet is duplicated then its
5922 reference count must be decresed by calling the free function as
5923 many times as it was duplicated.
5925 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5926 from both client and server.
5928 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Made joining to a channel working in router environment.
5932 * Cleaned up JOIN command on server side and create function
5933 silc_server_command_join_channel internal routine to make the
5936 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Changed silc_command_pending list to SilcDList. Also, added
5939 `ident' field to SilcServerCommandPending structure to identify
5940 the reply and to call correct callback.
5942 Added silc_server_command_pending_check function to replace the
5943 corresnponding macro. The silc_command_pending list is not
5946 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5947 to set identifier to previously allocated Command Payload. It
5948 is used to set identifier for command when resending Command
5951 * Added silc_command_payload_encode_payload to encode Command
5952 Payload buffer from SilcCommandPayload structure.
5954 * Added silc_argument_payload_encode_payload to encode Argument
5955 payload buffer from SilcArgumentPayload structure.
5957 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Changed WHOIS command to support router connection on server side.
5960 The whois request is always sent to router unless the server is
5961 standalone server. After server has received the reply from the
5962 router will it send the reply to the client.
5964 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5965 broadcast received broadcast packet. The function is used only
5966 by router. The broadcast packet is always sent to the router's
5969 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5970 render given ID to printable string, for log files for example.
5972 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5974 * Made basic router to router connections working. At least they
5975 can now connect to each other but nothing really works the way
5976 they are supposed - yet.
5978 * Added new initiator token to RouterConnection configuration
5979 file in silcd/serverconfig.[ch]. It is used to tell whether we
5980 are the initiator to the remote router or whether we'll expect
5981 the other end to connect.
5983 * Moved registering of listener task to silc_server_init, hence
5984 the server starts listenning as soon as it is run, even if it
5985 does not have connections to other routers. Let's see how well
5988 * Changed default connection retry timeouts for more suitable in
5991 * Removed cipher and such arguments from silc_idlist_add_client
5992 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5993 Added new function silc_idlist_add_data to add the keys and stuff
5996 * Added SilcIDListData structure and added it to SilcClientEntry
5997 and SilcServerEntry as their first field in the structure. This
5998 way we can explicitly cast the ID entries to the SilcIDListData
5999 structure and get common data for the entries. In past, we had
6000 to first check what type of connection it is and then cast it to
6001 correct ID entry type. Now, we can directly cast the opaque
6002 pointer to the SilcIDListData (no matter what ID entry it actually
6003 is) and get the data needed.
6005 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6008 in some circumstances even if threre were timeout tasks, though not
6009 IO tasks, but tasks anyway. Now fixed.
6011 * Defined SilcServerConnection structure to hold connection specific
6012 stuff about directly connected servers and routers. The definition
6013 is currently in silcd/server_internal.h. I thought about having
6014 a bit more important role fro this struct but for now it is used
6015 only when connecting to other server (or router actually).
6017 * Added connecting retry support in server when connecting to
6018 router(s). The retry feature implement exponential backoff
6019 algorithm. Also, added SilcServerParams structure to hold default
6020 parameters for server. For now, it include these retry settings
6021 and are hard coded. After server is moded to be as Silc Server
6022 Library this structure will be more important.
6024 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Changed client librarys channel->clients table to SilcList and
6027 changed code accordingly.
6029 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6031 * Changed client's channel table to SilcList and changed code
6032 accordingly. Also changed SilcChannelClientEntry to include back-
6033 pointer to the channel so that client entry can use that structure
6034 as list as well and we have fast cross-reference to the channel.
6035 This change dramatically decreased the complexity of channel
6036 handling with client entry and vice versa (removed one extra
6037 loop when searching for channel entry from many functions).
6039 * Changed server->sim from table to SilcDList and changed code
6042 * NAMES command can now be used from user interface. It will show
6043 the user list on the channel, neatly.
6045 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6046 Code now saves realname of the user if it becomes available.
6048 * Renamed configure.in to configure.in.pre and made ./prepare
6049 script to automatically add correct version string to
6050 configure.in which it creates from configure.in.pre.
6052 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * NAMES command reply now shows users mode with the nickname when
6057 * Moved silc_client_ch[u]mode[_char] functions from
6058 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6059 place sucks, they are utility functions and should be in some
6062 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6064 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6067 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Added TRQ (efficient deque and list library) into lib/trq. This is
6072 a very good list library that is currently used in the SILC. Defined
6073 SilcList API over the library because I didn't like the API very
6074 much. See lib/trq/silclist.h for the API and examples of how to
6075 use the API. Fixed various places in the code to use the new
6076 SilcList API. The SilcList is meant for lists that has a structure
6077 already defined as a list. It is not suitable to add just some
6078 context to the list (in TRQ, the context is the list actually).
6080 So, I defined SilcDList that can be used for the purpose where
6081 predefined list structure does not exit. This can be used as
6082 such list. Now some context just can be added to the SilcDList.
6083 Currently this list is not used in the SILC just yet, though there
6084 are a lot places where this can replace dynamically allocated
6085 tables and I will fix these places, later, to use SilcDList.
6086 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6087 and use TRQ internally).
6089 Also fixed some annoying warning messages that the original TRQ
6090 code generated. Also minor changes to TRQ's Makefile.in.
6092 * Added support for querying by Client ID to both WHOIS and
6093 IDENTIFY commands into server, as required by the protocol.
6095 * Removed method function pointers from SilcBuffer structure. They
6096 weren't used to anything and just increased the context size for
6097 no good reason. This change also made silc_buffer_alloc and
6098 silc_buffer_free functions inline functions.
6100 * Disabled command flooding detection support until it's fixed so
6101 that it accepts commands in but does not execute them more than once
6104 * Added silc_net_localhost(), to return local hostname, into
6105 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6106 that must be initialized before calling silc_client_init.
6108 * Added new function: silc_server_send_notify_on_channels to send
6109 notify messages to all channels client has joined. It is assured
6110 that the message is sent only once per client.
6112 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6113 lib/silcutil/silcutil.[ch] as silc_format function. The new
6114 function is generic and is used by server as well, not only by
6115 the logging routines.
6117 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6118 the provided version string was not acceptable. Added new function:
6119 silc_ske_check_version into lib/silcske/silcske.h. The function
6120 must be implemented by the application (client or server) and it
6121 does not reside in the SKE library. The function checks the version
6122 string remote end sent.
6124 * Added back pointers (to opaque context and to SilcSocketConnection)
6125 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6127 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6128 duplicate packet context structure.
6130 * Changed `notify' client operation to send same arguments as client
6131 receives from server except for ID's. ID's are mapped to correct
6132 ID entry and that is returned. Also, if channel entry is not sent
6133 by server but the notify is for channel the channel entry is sent
6134 to application (otherwise application doesn't know that it is for
6135 channel (library gets it from packet's Destination ID)).
6137 * Added silc_client_remove_from_channels into client library to
6138 remove a client from all channels it has joined to. Used when
6139 received SIGNOFF notify from server. Added also new function
6140 silc_client_replace_from_channels to replace old ID entry with
6141 new ID entry on all channels. Used when received NICK_CHANGE
6144 * Fixed ID Cache list handling in silc_idlist_get_client in
6145 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6146 to get (or query) client by ID.
6148 * Updated TODO list.
6150 * Added connection authentication status message defined by the
6151 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6152 support for these into the code in client and server side.
6154 * Added generic function silc_client_send_command to send any command
6155 with variable argument list. Application should use this function
6156 to send commands if the command functions provided by the library
6157 does not suite for the application's user interface needs.
6159 * Added new `failure' client operation. Application is notified about
6160 received failure packet if client is executing a protocol. In this
6161 case the protocol's execution has failed.
6163 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6164 is required by the protocol.
6166 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6167 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6170 * Added status flag to SilcSKE object to indicate realtime status
6171 of the SKE protocol.
6173 * Application receives now exactly same command reply arguments as
6174 the library receives from server. However, if ID is received the
6175 corresponding ID entry is returned to the application (eg. Client
6176 ID is mapped to correct SilcClientEntry entry and that is returned).
6177 Changed command_reply client operation due to this change.
6179 * Changed all ID's in commands and in command replys as ID Payloads.
6180 Change affected both client and server side codes.
6182 All ID's sent in SILC network (with execption of ID's in SILC
6183 Packet header) are sent in ID Payload to support variable length
6186 * Server now notifies nick changes and notifies all clients on
6187 the channels about the new nickname (about the new Client ID,
6190 * Implemented CMODE command to change channel modes. Supports all
6191 channel modes defined by the protocol specs except ban and invite
6192 lists. (Also, private channel key mode is supported but support for
6193 setting private channel key in client is missing, thus, this mode
6194 has no effect on client side (except that server requires that the
6195 client uses private channel key and normal channel traffic does not
6198 Also, invite mode works per se, but INVITE command does not work
6199 yet correctly, so you can set channel as invite only channel but
6200 inviting clients to the channel does not work (it is yet to be
6201 thought what's the best way to do it).
6203 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6204 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6205 Implemented CUMODE command to change user's mode on the channel.
6206 Supports all modes defined by the protocol specs.
6208 * Added NAMES command reply to return users modes on the channel.
6210 * Removed unnecessary and slow ciphers from lib/silccrypt.
6212 * Set SO_KEEPALIVE option to connection sockets by default.
6214 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6216 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6217 redefined the Notify Payload into protocol specs.
6219 * Added silc_id_payload_parse_id to get ID directly from raw
6222 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6224 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6225 accept searching by Client ID as well.
6227 * Added support for LEAVE and SIGNOFF notify types in client library.
6229 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6230 to parse ID Payload from raw data.
6232 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6234 * Added flags parameter into silc_ske_assemble_security_properties
6235 function in lib/silcske/silcske.[ch].
6237 * Changed notify client operation to fit better for notify messages
6238 sent by server. The notify payload received from server is now
6239 passed to the application (after parsing it to SilcNotifyPayload).
6240 It is application's responsibility to retrieve the arguments
6241 from the payload and show the message the way it wants. The message
6242 sent by server is implementation specific.
6244 * Changed public keys to comply with the protocol specification.
6245 Old public keys are not supported anymore and are not compatible.
6247 * Removed nickname from Channel Payload as the latest draft removed
6248 it. The client must resolve the nickname from the NAMES command
6249 reply received when it joined the channel.
6251 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6253 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * Fixed some errors in protocol specification drafts.
6257 * Created lib/silccore/silcnotify.c to implement Notify Payload
6258 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6259 generic payloads described by protocol specifications. The file
6260 includes implementations for ID Payload and Argument Payload.
6262 * Changed Command Payload implementation to use the new Argument
6263 Payload. Changed command_xxxx_payload to command_payload_xxxx
6264 to comply with SILC coding conventions.
6266 * Added suppport for Argument Payload handling in Notify Payload
6267 implementation as protocol requires it. Added the new support
6268 into server and client lib as well.
6270 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * Added support for multiple nicknames on same channel. [n] is
6273 added locally to the nickname if there are more than one same
6274 nicknames on the channel.
6276 * Server now sends all nicknames that matched WHOIS request.
6277 Client also shows the list received from server.
6279 * Added TOPIC command to client side. User can now set and show
6280 current topic on channel.
6282 * Added MOTD command to client and server. Also, server sends the
6283 motd when client connects to the server.
6285 * Changed version strings to comply ISO 8601.
6287 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6289 * Fixed protocol error handling in client library. It should now
6290 cope even if the SKE fails for some reason.
6292 * Made new protocol specification drafts for submitting to IETF.
6294 * Implemented TOPIC command to server in silcd/command.c.
6296 * Added two new notify types into lib/silccore/silcnotify.h:
6297 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6298 notify nickname change and topic setting/change on a channel.
6300 * API change of command_reply operation in client library. The
6301 application gets now the status type received from server as well.
6303 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6305 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6307 * Cras fixed and optimized the packet handling even further and
6308 it should work now. Minor change to the prototype of function
6309 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6311 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * Added new function into lib/silcutil/silcschedule.[ch]:
6314 silc_schedule_with_fd to select() a specified fd. The function
6315 returns after timeout expires or data arrives or goes. The
6316 function is used by packet routines to wait that all data is
6317 received from network.
6319 * Fixed data reading from network in lib/silccore/silcpacket.c.
6320 The code now assures that all data is read from the fd and then
6321 continues packet processing. This was a bug fix since the code
6322 used to drop some data in some circumstances.
6324 * Added new function into lib/silcclient/client.[ch]:
6325 silc_client_start_key_exchange to start key exchange after
6326 connection has been established to server. The code internally
6327 now uses this funtion but its main purpose was to provide it
6328 for applications that perform their own connecting. After
6329 application has created a connection it merely calls this
6330 function to start the key exchange between client and server.
6331 The library takes care of everything else after that.
6333 Updated also lib/silcclient/README to explain the usage of
6336 * Do not send to application information that connection has
6337 been established. Application gets notified it by connect
6340 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6342 * Applied cras's patch to add silc_schedule_one function. The
6343 function runs scheduler once and returns.
6345 * Fixed the scheduler after cras messed it up. The timeout
6346 handling works now as it's supposed to work.
6348 * Added into lib/silccore/ silcnotify.h to include notify
6349 message types support. Changed silc_server_send_notify*
6350 functions, in server.[ch], to support those new notify types.
6351 Added the support for the notify types into client library,
6352 as well. Added new notify client operation into ops.h in
6355 * Changed silc_server_packet_send_to_channel to send normal
6356 packets instead of just channel message packets. The function
6357 is now used to send the notify packets to channels. It is not
6358 used to send channel message packets anymore, as server never
6361 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6362 va_arg()s as it seems to require it nowadays. I guess, if SILC
6363 is compiled with older va_arg() the new code should work anyway.
6365 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Splitted core library. Core library (lib/silccore) includes
6368 now only SILC protocol specific core (and common) components.
6369 Created new utility library (lib/silcutil) that includes more
6370 generic purpose stuff. The stuff for util library was taken
6371 from the old core library. This was minor and easy split.
6373 * Created SILC Client Library (lib/silcclient) that includes
6374 implementation of the SILC client without user interface. This
6375 was major move from silc/ directory. The code has been changed
6376 so that it is transparent towards the user interface. The
6377 silc/ directory includes now the same user interface as before
6378 and it uses the new client library. Read lib/silcclient/README.
6379 Basicly, the client library performs everything else related
6380 to SILC except user interface handling. Also, configuration
6381 files are considered to be part of user interface and library
6382 does not handle them.
6384 This change also changed a lot of structures, function naming etc.
6385 Most important change was that SilcClientWindow object was
6386 renamed to SilcClientConnection in the client library. Created
6387 also new file lib/silcclient/ops.h. Also added new files
6388 silc/local_command.[ch] and silc/client_ops.[ch].
6390 All these changes were made to make it easier for user interface
6391 designers to create what ever user interface for the SILC client
6394 It is also expected that the server will be moved to lib
6395 directory as well and SILC Server Library will be created;
6396 sometimes in the future.
6398 * Removed Local commands from lib/silccore/silccommand.h as
6399 they are application specific and new client library does not
6400 handle any of those anymore.
6402 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6403 old client implementation in silc/.
6405 * Added support for callback functions in SILC_LOG_* macros.
6406 Application can now set its own callbacks that will be called
6407 instead of using the default functions that will always print
6408 the debug messages to stderr (or stdout). Also, debugging can
6409 now be disabled by setting silc_debug to FALSE and re-enabled by
6410 setting it to TRUE. Note, that logging will still work even
6411 if debugging is disabled.
6413 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6414 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6415 silc_log_reset_debug_callbacks.
6417 * To enable debugging in silc client one must give now -d
6418 option on command line.
6420 * Changed silc_schedule_init to automatically allocate task queues
6421 if they are not allocated before calling it.
6423 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Added GMP 3.1 into math library.
6427 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6430 a channel in SILC network. The packet is used by servers and
6431 routers to notify other routers that user has left a channel.
6432 This little feature was missing until now. Added the feature
6433 to protocol specification as well.
6435 Added functions: silc_server_send_remove_channel_user and
6436 silc_server_remove_channel_user into server.[ch].
6438 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6439 lib/silccore/silcpacket.h. However, they are not implemented
6442 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6444 * Fixed joining to a channel and sending channel messages
6445 between server and router. The channel message sending should
6446 now work inside a cell.
6448 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6450 * Fixed the private message sending between server and router.
6451 The private message sending should now work inside a cell.
6453 * Added silc_server_replace_id into server.[ch] to replace
6454 existing ID in the SILC network.
6456 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6457 and silc_idlist_replace_server_id into idlist.[ch] in server.
6459 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Fixed the server to server connections. Server can again now
6462 connect to router. Router to router connections probably does
6465 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6467 * Added dynamic protocol registering support. Now protocols can
6468 registered and unregistered on the fly. Patch by cras.
6470 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6472 * Added lib/contrib directory to hold routines that some platforms
6473 don't have but are needed by SILC.
6475 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6476 into lin/contrib to provide getopt() and getopt_long() for
6477 those who don't have it.
6479 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6481 * Added AWAY command to client. When away message is set and
6482 client receives a private message packet the client automatically
6483 replies to the sender with the away message.
6485 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6486 bug seemed to be the cause of recent problems when compiling
6489 * Added version detection support to SKE protocol specification
6490 and added the new changes to the SKE implementation as well.
6491 There were other minor changes in the SKE protocol as well.
6493 Many changes in lib/silcske/silcske.[ch] and in
6494 lib/silcske/payload.[ch].
6496 * Added ^U functionality, clear input line. Patch from cras.
6498 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6500 * Mainly small bugfixes on core library. Fixed some debugging
6501 logging and buffer overflow in silclog.c.
6503 * Updated config.sub and config.guess on the distribution tree.
6505 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Added command lagging support in server. Client may execute
6508 commands now only once in two seconds.
6510 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6512 * Optimized packet reception. MAC computation and checking is now
6513 also more optimized. A lot previously duplicated code is now
6514 used as generic by both client and server.
6516 * Fixed key pair generation in clientutil.c
6518 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6520 * Added into lib/silccore/silcbufutil.[ch] new function;
6521 silc_buffer_realloc.
6523 * Moved generic packet sending/encryption functions to
6524 lib/silccore/silcpacket.[ch] from client and server. Some
6525 rewriting of the functions.
6527 * Moved all generic packet reception/decryption functions to
6528 lib/silccore/silcpacket.[ch] from client and server. The
6529 packet processing is now much cleaner in both client and server.
6530 These were major changes in both client and server.
6532 * Created many common functions in server to do packet sending.
6533 Previously code were duplicated a lot, this has been removed
6536 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6538 * Rewrote major parts of the ID cache system. Don't know
6539 whether it is better now or not but at least the API is more
6542 * Major rewrite on ID cache stuff on client because of the ID
6543 cache API changes. Added idlist.c to client.
6545 * Also major rewrite on ID cache stuff on server as well.
6546 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6547 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6548 in hand, instead they are all put into the ID cache system now.
6549 All server_idlist_* routines uses ID cache now instead of
6550 traversing its own lists (those lists does not exist anymore).
6551 SilcIDList though still exists. Also, SilcXXXEntry's are
6554 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Finally made the SKE implementation compliant to the protocol
6557 specification. All mp integers are now binary encoded as
6558 opposed being HEX encoded.
6560 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6563 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6564 functions: silc_[encode/decode]_pem. Also added function
6565 silc_encode_pem_file to PEM encode with newlines ('\n') for
6568 * SILC public keys are now encoded either PEM or binary. Same
6569 option is for private keys as well. By default private keys
6570 are binary encoded and public keys PEM encoded. Silly HEX
6571 encoding were removed.
6573 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6574 function to create fingerprints.
6576 * Fixed a bug in SHA1; does not change the original data anymore.
6578 * Partly implemented INFO command on client and server side.
6579 Fixed CLEAR command. Changes to SERVER command; show current
6580 server(s) when giving command without arguments. Added
6581 VERSION command to client.
6583 * Added check to server that unregistered connections cannot
6584 execute commands (unless it is specificly allowed).
6586 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Fixed screen refresh.
6590 * Fixed channel joining bug from client. On some circumstances
6591 client tried to join to a channel it had already joined.
6593 * Added public key verification process into client's protocol.c.
6594 The client now verifies the public key from user and saves
6595 it into ~./silc/serverkeys/ directory.
6597 Added into: clientutil.[ch]: silc_client_verify_server_key.
6599 * Changed SKE protocol's silc_ske_initiator_finish function
6600 to accept callback function that verifies the received public
6601 key. Removed old silc_ske_verify_public_key function.
6603 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6605 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6606 silc_pkcs_private_key[_data]_set.
6608 * Made the password and public authentication more cleaner in
6609 server's protocol.c.
6611 * Removed historic and obsolete protocol `channel_auth' from
6612 both client and server.
6614 * Removed wrong way of sending command status messages from
6615 server to client in server's command.c. The old way violated
6616 protocol specification.
6618 Changes to silccore/silccommand.[ch]: removed
6619 silc_command_encode_status_payload -> not needed anymore,
6620 changed silc_command_encode_payload_va to accept extra
6621 argument on variable argument list. The argument type must
6622 now be provided to the function. Also, added new function:
6623 silc_command_encode_reply_payload_va which is same as
6624 normal command_encode_payload_va except command status type
6625 is provided as extra argument.
6627 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Added ~./silc directory handling. The directory includes the
6630 public and private keys for the client.
6632 Added silc_client_check_silc_dir, silc_client_create_identifier
6633 and silc_client_load_keys.
6635 * Implemented SILC protocol compliant public key. Added public
6636 and private key saving to and loading from files.
6638 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6639 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6640 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6641 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6642 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6644 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6645 silc_pkcs_load_[public/private]_key.
6647 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Added silc_server_get_route (route.[ch]) to get connection
6650 data for the fastest route for given ID.
6652 * Implemented INVITE command on client and server. The command
6653 were re-defined in the SILC Protocol Specification and the
6654 implementation now complies with the specification.
6656 * Implemented PING command on client and server.
6658 * Implemented NAMES command on client and server. The server side
6659 supports currently only normal server not router server yet.
6660 Some changes to NAMES definition in SILC protocol specification.
6662 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6664 * Implemented LEAVE command on client and server.
6666 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6667 again. This change was made to the protocol as well. Server
6668 should not violate the protocol specification anymore.
6670 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6672 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6673 was tested. SOCKS4 was not but should work anyway.
