1 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Applied patches from cras:
5 Memory leak fixes around libaries, irssi window resize fix,
6 new silclist.h and silcdlist.h, all extern inline changed to
9 * Removed dotconf from lib/dotconf, not needed anymore.
11 * Removed TRQ from lib/trq, not needed anymore.
13 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
14 with server connections. Later this will be configurable
15 in config file after new config file is done. Affected file
18 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
20 * Fixed a crash in server related to channel announcements.
21 Affected file silcd/server.c.
23 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
25 * Fixed memory leaks in silc_server_create_new_channel*
26 functions. Affected file silcd/server.c.
28 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
29 which ID was changed. This way the router will send the
30 user list for the channel again, and server won't be in
31 desync in some rare circumstances. Affected file is
32 silcd/packet_receive.c.
34 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
36 * Check for NULL socket pointer in the function
37 silc_server_packet_send_to_channel_real. Affected file
40 * Fixed the BAN notify handling to correctly remove ban
41 list. Affected file silcd/packet_receive.c.
43 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
45 * Fixed some header addition to Toolkit distribution in
46 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
48 * Added lib/silcclient/client_ops_example.h as an template
49 file for application programmers to quickly start using
50 the SilcClientOperation functions in their application.
51 Updated the lib/silcclient/README as well to tell about this
52 nice file made available.
54 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
56 * Call silc_server_remove_from_channels when removing client
57 entry when NO_SUCH_CLIENT_ID was received. Affected file
58 is silcd/command_reply.c.
60 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
62 * Added server & router operator statistics updating. Affected
63 file silcd/packet_receive.c and silcd/command.c.
65 * Fixed the SERVER_SIGNOFF notify handling on normal server
66 not to save the history information for clients. Same was
67 fixed earlier in remove_clients_by_server function, but not
68 here. Affected file silcd/packet_receive.c.
70 * Raised the default connection-retry count from 4 to 7 in
71 server. Affected file silcd/server.h.
73 * Cancel any possible reconnect timeouts when we start the
74 key exchange. Affected file silcd/server.c.
76 * Do not reconnect on connection failure when SCONNECT was
77 given. Affected files silcd/server.[ch].
79 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
81 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
83 * Fixed the NICK command to always give the unformatted
84 nickname to the one giving the NICK command. If unformatted
85 nickname is cached already it will be formatted and the
86 local entry will always get the unformatted nickname.
87 Affected file lib/silcclient/idlist.c.
89 * Fixed some double frees from client library commands.
90 Affected file is lib/silcclient/command.c.
92 * Fixed CUMODE command in server to assure that no one can
93 change founder's mode than the founder itself, there was a
94 little bug. Affected file silcd/command.c.
96 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
98 * Removed the SilcClientCommandDestructor from the client
99 libary, it is not needed anymore. Affected files are
100 lib/silcclient/silcapi.h, command[_reply].[ch],
101 client_notify, idlist.c.
103 * Fixed GETKEY command to first resolve client, and then
104 resolve the server only if the client was not found, instead
105 of resolving both at the same time. Affected file is
106 lib/silcclient/command.c.
108 * Added silc_client_start_key_exchange_cb and lookup the
109 remote hostname and IP address before starting the key
110 exchange with server. The affected file is
111 lib/silcclient/client.c.
113 * The server's public key is now saved using the IP address
114 of the server and not the servername for the filename.
115 The hostname public key filename is checked as an fall back
116 method if the IP address based filename is not found.
118 Fixed the GETKEY command to save the fetched server key
121 Print the remote server's hostname now when new key is
122 received during connection process. Affected file is
123 irssi/src/silc/core/client_ops.c.
125 * Return always our own public key to the client if it asks
126 for it with GETKEY command. Affected file silcd/command.c.
128 * Removed the use_auto_addr variable from default config
129 file since it was in wrong section. Affected file is
132 * Fixed TOPIC_CHANGE notification to not route it when it
133 was sent using silc_server_send_notify_to_channel function.
134 Affected file silcd/command.c.
136 * Fixed silc_server_send_notify_kicked to send the kicker's
137 Client ID also, it was missing. Affected files are
138 silcd/command.c, silcd/packet_send.[ch].
140 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
142 * Do not save client history information in SERVER_SIGNOFF.
143 Fixes the bug in normal server that it does not detect
144 the client becoming valid after the server becomes back
145 online. Affected file silcd/server_util.c.
147 * Added `sock_error' field into the SilcSocketConnection
148 context. When error occurs during socket operation (read
149 or write) the error is saved. Added also new function
150 silc_socket_get_error to return human readable socket error
151 message. Affected files are lib/silcutil/silcsockconn.[ch],
152 lib/silcutil/unix/silcunixsockconn.c, and
153 lib/silcutil/win32/silcwin32sockconn.c.
155 * The server now prints the socket error message in the
156 signoff for client. Affected file silcd/server.c.
158 * Fixed the `created' channel information sending from router
159 to server in JOIN command. Checks now whether the channel
160 really was created or not and set it according that.
162 Fixed the JOIN command to use the client entry's current
163 ID during the joining procedure instead of the one it sent
164 in the command (it is checked though), since it can change
165 between the packet processing and command processing, and
166 would just case unnecessary pain in the client end. Affected
167 file silcd/command.c.
169 * Fixed a channel key payload sending to use correct channel
170 ID when the server was forced to change the channel's ID by
171 router. Router sent the key payload with the old Channel ID.
172 Affected file silcd/packet_receive.c.
174 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
176 * Call silc_server_save_channel_key only if the key payload
177 was provided in the JOIN command's command reply. Affected
178 file silcd/command_reply.c.
180 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
182 * Fixed silc_mp_sizeinbase to return the value correctly with
183 MPI. Affected file lib/silcmath/mp_mpi.c.
185 * Fixed the stop_server signal to correctly stop the scheduler
186 and gracefully stop the server when SIGTERM or SIGINT signals
187 are received. Affected file silcd/silcd.c.
189 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
191 * Simple handling of TERM and HUP signals. Also added some log
192 flushing call around. Affected file is
195 * Fixed small bugs in silclog.c. Now buffering output will take
196 effect after 10 seconds since startup: This will ensure that
197 no important startup messages are lost. Also output redirection
198 will preserve original format ([Date] [Type] message).
199 Affected file is lib/silcutil/silclog.c.
201 * Added two options to the config file, in the logging section:
202 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
203 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
205 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
207 * Do not print the warning about log files not being initialized
208 more than once to avoid excess logging. Affected file is
209 lib/silcutil/silclog.c.
211 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
212 the SIM copying in make install in Makefile.am.pre.
214 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
216 * Rewritten silclog APIs. Globally interesting changes follows:
217 silc_log_set_files() changed to silc_log_set_file().
218 silc_log_set_callbacks() changed to silc_log_set_callback().
219 ROBOdoc documented silclog header file.
220 SilcLogCb now returns bool to wether inihibit the default
221 handler or not (to keep the old behaviour return always TRUE).
222 The new APIs should also fix the problem of the
223 silcd_error.log file that was written in the current directory.
226 Log files streams will remain opened after silc_log_set_file()
227 call, means less CPU usage notably on high traffic servers.
228 File streams are now full buffered, and flushed to the disk
229 every 5 minutes, lesses HD activity and CPU usage.
230 Messages can be redirected, allowing admins to configure
231 one single logfile for all server messages.
232 the silc_log_quick global variable to activate fast-logging.
233 Affected files lib/silcutil/silclog.[ch]
235 * Changed some code to conform new silclog APIs. Affected
236 files are doc/example_silcd.conf.in, silcd/server.c
237 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
240 * Fixed a memory leak that could occur in some situations.
241 Affected file silcd/serverconfig.c.
243 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
245 * Added the silc_client_del_client to remove the client from
246 all channels as well. Affected file lib/silcclient/idlist.c.
248 * Fixed the client library to correctly remove the client
249 from all channels when the client entry is being destroyed.
250 Affected file lib/silcclient/client_notify.c, command.c.
252 * Added auto-nicking support to the client library. If the
253 applicatio now sets client->nickname it will be sent to the
254 server after connecting by the library. This way for example
255 SILCNICK (or IRCNICK) environment variables will have effect
256 and always change the nickname automatically to whatever
257 it is wanted. Affected file lib/silcclient/client.[ch].
259 * Renamed silc_server_command_bad_chars to the
260 silc_server_name_bad_chars and moved it to the
261 silcd/server_util.[ch]. Added also new function
262 silc_server_name_modify_bad to return nickname that
263 includes bad characters as new nickname without those
264 bad characters. This check and modify is now used in
265 silc_server_new_client when the username is initially set
266 as nickname, so it must be checked to be valid nickname.
267 Affected file silcd/packet_receive.c.
269 * The nickname length is now taken from the packet for real
270 and not trusted to strlen() since it clearly can return
271 wrong length for nickname including bad characters. This
272 also applies to channel names. Affected file silcd/command.c.
274 * Removed the lib/silcsilm/modules directory. Modules are now
275 compiled into the lib/silcsim. Fixed the copying of the
276 modules to follow symbolic links in Makefile.am.pre.
278 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
280 * Fixed silc_string_regexify list creation. Fixes bugs with
281 BAN and INVITE commands in server. The affected file is
282 lib/silcutil/unix/silcunixutil.c.
284 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
286 * Removed the command destructor entirely from the server's
287 command and command reply routines. It is not needed, and
288 its usage was buggy and caused crashes. Affected files are
289 silcd/command[_reply].[ch].
291 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
293 * Cancel protocol and NULL sock->protocol if timeout
294 occurred during protocol. Affected file silcd/server.c.
296 * Cancel protocol timeouts always before calling the final
297 callback, to assure that after final callback is called
298 no other state will be called for the protocol anymore.
299 Affected file silcd/protocol.c.
301 * Print error log if incoming connection configuration could
302 not be found. Affected file silcd/server.c.
304 * Fixed JOIN command to correctly save the founder mode
305 to the client on normal SILC server, when the channel
306 was created by the router. Affected file silcd/command.c.
308 * Fixed LIST command (hopefully) to send correct reply
309 packets. Affected file silcd/command.c.
311 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
313 * The silc_packet_receive_process now returns FALSE if the
314 read data was invalid packet, and TRUE if it was ok.
316 The server now checks that if unauthenticated connection
317 sends data and its processing fails the server will close
318 the connection since it could be a malicious flooder.
320 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
322 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
324 * Make sure the warning about error opening a log file is
325 printed only once and not everytime it fails (produces
326 too much useless log). Affected file lib/silcutil/silclog.c.
328 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
330 * Made the silc_server_daemonise() function more readable.
331 Affected file silcd/server.c.
333 * Pid file is now optional, the user may comment it out from
334 the config file. Removed define SILC_SERVER_PID_FILE, we
335 don't need a default any longer. Affected file
336 configure.in.pre, lib/Makefile.am.pre.
338 * Make some use of the pid file. The server now dies at startup
339 if it detects a valid pid file on his path. The server would
340 die anyway in this circumstance, because of the bind() failure.
341 Affected file silcd/silcd.c.
343 * No longer compiling lib/dotconf.
345 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
347 * Fixed JOIN command parsing not to crash. Affected file
348 lib/silcclient/command.c.
350 * Fied the NICK_CHANGE notify to add the new client entry
351 even it is resolved. This removes an <[unknown]> nick
352 thingy bug in the client. Affected file is
353 lib/silcclient/client_notify.c.
355 * Do not try to allocate 0 bytes (efence does not like it)
356 in lib/silccore/silccomand.c when encoding payload.
358 * Do not take IRCNICK as nickname in Irssi SILC client since
359 it is not possible to set nickname before hand connecting
360 the server (TODO has an entry about adding auto-nicking
363 * Changed the silc_server_command_pending to check whether
364 there already exists an pending entry with the specified
365 command, command identifier and pending callback. This is
366 to fix IDENTIFY and WHOIS related crashes that may register
367 multiple pending commands with same identifier. Affected
368 file silcd/command.c.
370 * Fixed the server to reconnect to the router even if it
371 was already reconnecting and EOF was received. This to
372 fix a possibility that the server wouldn't ever try to
373 auto-reconnect to the router. Affected file silcd/server.c.
375 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
377 * Fixed the server's password authentication to use the
378 length of the locally saved password, and not the one
379 sent in the packet. Affected file silcd/protocol.c.
381 * Fixed same password authentication problem in the
382 Authentication Payload handling routines in
383 lib/silccore/silcauth.c.
385 * Yet another password authentication problem fixed with
386 channel password handling in silcd/command.c.
388 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
390 * If first character of string in silc_parse_userfqdn is '@'
391 then do not parse it. Affected file is
392 lib/silcutil/silcutil.c.
394 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
396 * Fixed minor bug in IDENTIFY command reply sending, which
397 caused various weird problems during JOIN when it was
398 resolving names for users. Affected file silcd/command.c.
400 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
402 * Fixed the IDENTIFY command reply sending to chech better valid
403 clients. It was possible to send incomplete list of replies.
404 Affected file silcd/command.c.
406 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
408 * Added silc_client_command[s]_[un]register functions now to
409 dynamically register the commands in client library. Removed
410 the static table of commands. This allows the client library
411 to call commands without causing the application to know about
412 what commands library has called.
414 Removed the INFO command reply kludge to detect when the command
415 was called by library. Now library use its own command reply
416 function for INFO command.
418 Added function silc_client_command_call to call a command.
419 Application can use it to call command, not access the structure
422 Now all commands that are sent by the client library (not
423 explicitly sent by application) use own command reply functions.
425 Affected files around lib/silcclient/ and in
426 irssi/src/silc/core/.
428 * Fixed the WHOIS command reply sending to chech better valid
429 clients. It was possible to send incomplete list of replies.
431 Fixed the WHOIS and IDENTIFY to send the request to router
432 if normal server did not do it and did not find any results.
434 Affected file silcd/command.c.
436 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
438 * Moved the internal data from SilcClient context into its
439 own file, not accesible to application. Affected files
440 lib/silcclient/client.h and lib/silcclient/client_internal.h,
441 and other files in client library.
443 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
445 * Added doc/examples installation target in Makefile.am.pre.
448 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
450 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
451 commands the found client entry will be removed from the
452 cache, after notifying application about the error. Affected
453 file lib/silcclient/command_reply.c.
455 * Changed the /MSG to check for exact nickname user gave, and
456 not let `nick' match `nick@host' if it is only one found. Now,
457 user must type the exact nickname (like nick@host2) even if
458 there are no more than one same nicks found. This is to avoid
459 a possibility of sending nickname to wrong nickname since
460 `nick' could match `nick@host'. Affected file is
461 irssi/src/core/silc-servers.c.
463 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Do not print "you are now server operator" or similar when
466 giving /away command. Affected files are
467 irssi/src/silc/core/client_ops.c, silc-servers.h.
469 * Made the silc_server_command_pending_error_check to send
470 the same command reply payload it received back to the
471 original sender of the command. This way all arguments
472 that was received by the server will be received by the
473 client too. Affected file silcd/command.c.
475 * Added the silc_idcache_add to return the created cache entry
476 to a pointer. Affected file lib/silccore/silcidcache.[ch].
478 * Add global clients to expire if they are not on any channel.
479 This is because normal server will never know if they signoff
480 if they are not on any channel. The cache expiry will take
481 case of these entries. This is done by normal servers only.
482 The affected files are silcd/command_reply.c,
483 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
485 * If server receives invalid ID notification for WHOIS or
486 IDENTIFY and the ID exists in the lists, it is removed.
487 Affected file silcd/command_reply.c.
489 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
490 in client then client entry that it matches is searched and
491 the nickname is printed on the screen for user. Affected
492 file irssi/src/silc/core/client_ops.c.
494 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
496 * Use cache entry expire time in the LIST command reply to
497 purge old entries from the cache after the LIST command
498 reply has been received. This way we don't have non-existent
499 entries in the cache for too long. Affected file is
500 silcd/command_reply.c.
502 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
504 * If we are normal server, and we've not resolved client info
505 in WHOIS or IDENTIFY from router, and it is global client,
506 we'll check whether it is on some channel. If it is not
507 then we cannot be sure about its validity and will resolve it
508 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
509 file silcd/command.c.
511 * Search channel by name (if possible) rather than by ID
512 in IDENTIFY command's command reply. Affected file is
513 silcd/command_reply.c.
515 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
517 * Distribute to the channel passphrase in CMODE_CHANGE notify.
518 Updated specs and implemented it. Affected file silcd/command.c,
519 silcd/packet_send.c and silcd/packet_receive.c.
521 * Implemented the <founder auth> payload handling in the JOIN
522 command. If provided all conditions for channel joining
523 except requirement to provide correct passphrase can be
524 overrided by the channel founder. Updated the protocol specs.
525 Affected file silcd/command.c.
527 Added support for founder auth in JOIN command in client
528 library. Fixed the parsing of the JOIN command now to support
529 all options as they should be. The affected file is
530 lib/silcclient/command.c.
532 * Optimized the WHOIS and IDENTIFY commands to send the request
533 to router only if it includes nicknames or other names. If
534 they include only IDs then check the local cache first before
535 routing. Affected file is silcd/command.c.
537 * Added channels topic announcements. Affected file is
538 silcd/packet_receive.c and silcd/server.c.
540 * Fixed the silc_server_send_notify_topic_set to really destine
541 the packet to channel. Affected file silcd/packet_send.c.
543 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
544 library. Affected file lib/silcclient/client_notify.c.
546 * Added UMODE announcements. Affected file silcd/server.c.
548 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
550 * Memory leak fixes in:
552 lib/silcutil/silcsockconn.c
553 lib/silcske/silcske.c
556 lib/silccrypt/silcpkcs.c
557 lib/silccore/silccommand.c
558 lib/silccore/silcidcache.c
563 * ROBOdoc documented the lib/silcske/groups.h file and a
564 bit changed the interface for better.
566 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
568 * Update the client entry context in the ID cache after
569 nick change. Affected file lib/silcclient/command.c.
570 Fixes the CUMODE command when regaining founder privileges,
571 and a little WHOIS problem.
573 * Fixed silc_net_gethostbyname to correctly call the
574 inet_ntop. Affected file lib/silcutil/silcnet.c.
576 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
578 * Added IPv6 support checking to the configure.in.pre, added
579 also --enable-ipv6 option to override the check. Affected
580 file configure.in.pre.

606 * Fixed LIST command reply sending in server. Affected file
609 * Server now sends the kicker's client ID in the KICK notify
610 to the kicked client. Affected file silcd/command.c.
612 * The client library now parses the kickers client ID and
613 UI displays it. Affected files lib/silcclient/client_notify.c
614 and irssi/src/silc/core/silc-channels.c, module-formats.c.
616 * Made all payload parsing function prototypes consistent.
617 They all take now const unsigned char * and uint32 pair as
618 the payload data instead of SilcBuffer. Changes all around
619 the source tree. Other unsigned char* -> const unsigned char*
620 changes around the tree as well.
622 * Optimized SFTP client and server packet sending not to
623 allocate new buffer for each packet but to recycle the
624 first allocated buffer. Affected files are
625 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
627 * Optimized the SFTP client to use SilcList instead of
628 SilcDList for requests, because it is faster. Affected file
629 is lib/silcsftp/sftp_client.c.
631 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
632 into lib/silccore/silcid.[ch].

636 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
638 * If client entry is deleted with active key agreement
639 session, abort the session.
641 The silc_client_abort_key_agreement now calls the completion
642 callback with new SILC_KEY_AGREEMENT_ABORTED status.
644 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
647 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
649 * Don't use __restrict in older GCC's. Affected file is
650 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
652 * silc_net_localhost now attempts to reverse lookup the
653 IP/hostname. Affected file lib/silcutil/silcnet.c.
655 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
656 command. It can be used to gain founder privileges at
657 the same time when joining the channel.
659 Defined that the SILC_NOTIFY_TYPE_KICKED send the
660 kicker's client ID as well. Updated protocol specs.
662 Defined that the server must send SILC_COMMAND_IDENTIFY
663 command reply with error status to client who sent
664 private message with invalid client ID.
666 Updated the protocol specification.
668 * Added silc_server_send_command_reply to send any
669 command reply. Affected file silcd/packet_send.[ch].
671 * Added silc_id_payload_encode_data to encode ID payload
672 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
674 * The server now send IDENTIFY command reply with error
675 status if client ID in private message is invalid. Affected
676 file silcd/packet_receive.c.
678 * Save the server key file with server's IP address in
679 the filename instead of hostname. The affected file is
680 irssi/src/silc/core/client_ops.c.
682 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
684 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
687 * Added libtool support for compiling shared objects in
688 lib/silcsim. Affected file configure.in.pre and
689 lib/silcsim/Makefile.am. Original patch by cras.
691 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
693 * Pid file configuration, and server's config file fixes
694 patch by toma. Updated CREDITS file.
696 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
698 * Fixed silc_client_channel_message to not try to decrypt
699 the message twice if it resolved the destination client
700 information. This could cause of dropping one channel
701 message. Affected file lib/silcclient/client_channel.c.
703 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
705 * Added silc_client_run_one into lib/silcclient/silcapi.h and
706 lib/silcclient/client.c. This function is used when the SILC
707 Client is run under some other scheduler, or event loop or
708 main loop. On GUI applications, for example this may be
709 desired to used to run the client under the GUI application's
710 main loop. Typically the GUI application would register an
711 idle task that calls this function multiple times in a second
712 to quickly process the SILC specific data.
714 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
716 * Fixed silc_server_drop() for dropping the supplementary
717 groups as well, this could cause a security hole on some
720 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
722 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

726 to run server on foreground. A patch by debolaz.
727 Affected files silcd/server.c, silcd/silcd.c.
729 * Fixed MOTD to return the MOTD file server name. Affected
730 file silcd/command.c.
732 * Added INFO command reply handling to the Irssi SILC Client.
733 Affected file irssi/src/silc/core/client_ops.c.
735 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
737 * Fixed the silc_idcache_list_* routines to really support
738 the dynamic list. Fixes a crash. Affected file is
739 lib/silccore/silcidcache.c.
741 * Fixed the LIST command reply to really call LIST command's
742 pending callbacks. Affected file silcd/command_reply.c.
744 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
746 * Update conn->local_entry->nickname after giving NICK
747 command. Affected file lib/silcclient/command.c.
749 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
751 * Added the [pid] option to the silcd configuration file
753 Affected files: serverconfig.[ch] and silcd.c

757 * Save fingerprint in WHOIS command reply in server.
758 Affected file silcd/command_reply.c.
760 * Fixed NICK commands pending callback registration.
761 Affected file lib/silcclient/command.c.
763 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
765 * Use ++server->cmd_ident when sending commands in server,
766 instead of random number. Affected file silcd/command.c.
768 * Fixed GETKEY command reply to call actually GETKEY pending
769 command callbacks. Affected file silcd/command_reply.c.
771 * A bit stricter check for nicknames. Check for same nickname
772 in NICK command also. Affected file silcd/command.c.
774 * Do not call INFO command everytime client ID changes, only
775 during first connecting. Affected file lib/silcclient/client.c.
777 * Set the new nickname only after successful command reply for
778 NICK command is returned by server. Affected file
779 lib/silcclient/command.c.
781 * Remove nicknames from nicklist during server_signoff notify.
782 Should fix /NAMES bit more. The affected file is
783 irssi/src/silc/core/silc-channels.c.
785 * Added `fingerprint' field to the SilcIDListData in the
786 silcd/idlist.h to hold the fingerprint of the client's
789 Send the fingerprint of the client's public key in WHOIS
792 Affected files silcd/command.c, and silcd/idlist.[ch].
794 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
795 create fingerprint from given data.
797 * Show the fingerprint of the client's public key in WHOIS.
798 Affected files irssi/src/module-formats.[ch] and
799 irssi/src/silc/core/client_ops.c.
801 * Format the multiple same nicknames also during JOIN and
802 NICK_CHANGE notifys. Affected file is
803 lib/silcclient/client_notify.c.
805 * Do not print error on screen for invalid private message
806 payload since it can come if someone is sending private
807 messages with wrong key. Affected file
808 lib/silccore/silcprivate.c.
810 * Fixed multiple concurrent /PING crash. Affected file
811 lib/silcclient/command.c.
813 * Changed the wrong ID encoding. All IP addresses must be
814 in MSB first order in encoded format. They were encoded
815 wrong and was in LSB format. Affected files are
816 silcd/serverid.c, lib/silcutil/silcutil.c.
818 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
820 * Call the `connect' client operation through the scheduler
821 in case of error. Affected file lib/silcclient/client.c.
823 * Call the `failure' client operation even if the error
824 occurred locally during a protocol. Affected file is
825 lib/silcclient/protocol.c.
827 * Added support of sending LIST command to router from normal
828 server. This way normal server can get list of all channels
829 in the network too. Fixed the channel list sending in the
830 server too. Affected files are silcd/command.c, and
831 silcd/command_reply.[ch].
833 * Added silc_server_update_channels_by_server and
834 silc_server_remove_channels_by_server. They are used during
835 disconnection of primary router and in backup router protocol.
836 Affected file silcd/server_util.[ch], silcd/server.c and
837 silcd/server_backup.c.
839 * Fixed channel adding to global list in IDENTIFY command
840 reply in server. Affected file silcd/command_reply.c.
842 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
844 * If the incoming packet type is REKEY or REKEY_DONE process
845 that packet always synchronously. Fixes yet another MAC
846 failed error on slow (dialup) connections. Affected file
847 lib/silcclient/client.c and silcd/server.c.
849 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
851 * Call check_version SKE callback for initiator too. Affected
852 file lib/silcske/silcske.c.
854 * Implemented fix for security hole found in the SKE that was
855 fixed in the specification few days back; the initiator's
856 public key is now added to the HASH value computation.
857 Added backwards support for the old way of doing it too, for
858 old clients and old servers. Affected file is
859 lib/silcske/silcske.c.
861 * Enabled mutual authentication by default in SKE. If initiator
862 is not providing mutual authentication the responder will
863 force it. This will provide the proof of posession of the
864 private key for responder. The affected files are
865 lib/silcclient/protocol.c and silcd/protocol.c.
867 * Do not cache anymore the server's public key during SKE.
868 We do mutual authentication so the proof of posession of
869 private key is done, and if the server is authenticated in
870 conn auth protocol with public key we must have the public
871 key already. Affected file silcd/protocol.c.
873 * Added new global debug variable: silc_debug_hexdump. If
874 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
875 file lib/silcutil/silclog.[ch].
877 * Fixed compilation warning due to char * -> const char *.
878 Affected files lib/silcutil/silcnet.h, and
879 lib/silccore/silcauth.[ch].
881 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
883 * Fixed CMODE command when new channel key was created. If
884 the creation failed the old key was removed. Next time giving
885 same command would crash the server since the old key was
886 freed already. Affected file silcd/command.c.
888 * Fixed the silc_server_announce_get_channels to not crash
889 on reconnect. Affected file silcd/server.c.
891 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
893 * Added silc_log_set_debug_string function to set a regex
894 string to match for debug output. Only the function names,
895 or filenames matching the given debug string is actually
896 printed. This way it is possible to filter out those debug
897 strings that user is not interested in.
899 Fixed a bug in silc_string_regexify.
901 Affected files lib/silcutil/silclog.[ch], and
902 lib/silcutil/unix/silcunixutil.c.
904 * Changed the -d options in both server and Irssi SILC client
905 to take the debug string as argument. Affected files
906 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
908 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
910 * Added silc_hash_babbleprint to create a Bubble Babble
911 Encoded fingerprint. The encoding is developed by Antti
912 Huima (draft-huima-babble-01.txt), and it creates human
913 readable strings out of binary data. Affected file
914 lib/silccrypt/silchash.[ch].
916 * Print the babble print now in addition of fingerprint as well
917 in Irssi SILC client. Affected files are
918 irssi/src/fe-common/silc/module-formats.[ch],
919 irssi/src/fe-common/silc/core/client_ops.c.
921 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
923 * Fixed a security problem found in SKE. The initiator's
924 public key too is now added to the HASH hash value creation
925 which is signed by the responder to create the SIGN value.
926 This will prevent anyone in the middle to lie to the responder
927 about the initiator's public key. If this is done now, the
928 man in the middle will get caught. Updated the protocol
931 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
933 * Better installation directory handling. Configure module
934 paths and other paths automatically to example_silc* files
935 in doc/. A patch by toma.
937 * Fixed compiler warning from MPI library, and from SILC RNG.
940 * Added SILC_SERVER_PID_FILE to define the pid file for server.
941 It can be configured with ./configure. A patch by toma.
943 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
945 * Find correct make to use in prepare-clean. A patch by
946 toma. Affected file prepare-clean.
948 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
950 * Added irssi variables use_auto_addr, auto_bind_ip,
951 auto_bind_port and auto_public_ip.
953 * Changed the interface for silc_client_send_key_agreement
954 in lib/silcclient/silcapi.h
958 irssi/src/silc/core/silc-core.c
960 lib/silcclient/silcapi.h
961 irssi/src/silc/core/silc-channels.c
962 lib/silcclient/client_keyagr.c
965 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
967 * Added silc_pkcs_public_key_compare to compare two
968 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
970 * Check that the client who set the founder mode on the
971 channel is the same client that is giving the founder
972 mode to itself. It is done by comparing the saved public
973 key (it is saved even in the authentication is passphrase).
974 Affected file silcd/command.c.
976 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
978 * Do not process packet for disconnected socket connection.
979 Affected file lib/silccore/silcpacket.c.
981 * Process the DISCONNECT packet through scheduler in the
982 client library. Affected file lib/silcclient/client.c.
984 * Fixed the silc_client_packet_parse to not to increase
985 the packet sequence number if the conn->sock and the
986 current socket connection is not same. This can happen
987 for example during key agreement when the conn includes
988 multiple socket connections (listeners). Affected file
989 lib/silcclient/client.c.
991 * The sender of the file transfer request now provides also
992 the pointer (listener) for the key exchange protocol. If
993 the listener cannot be created then it sends empty key
994 agreement and lets the receiver provide the listener.
996 Added `local_ip' and `local_port' arguments to the
997 silc_client_file_send. If they are provided they are used,
998 if not then it will attempt to find local IP address, if
999 not found or bind fails then the remote client will provide
1002 Affected files are lib/silcclient/client_ftp.c and
1003 lib/silcclient/silcapi.h.
1005 * Extended the FILE SEND command to support defining the
1006 local IP and port for key exchange listener. They are
1007 optional. Affected file irssi/src/silc/core/silc-servers.c.
1009 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1011 * Defined to WHOIS command reply the sending of fingerprint
1012 of the client's public key (if the proof of posession of the
1013 corresponding private key is verified by the server).
1014 Updated to the protocol specification.
1016 * Added support of receiving the client's public key's
1017 fingerprint in command reply in client library. Affected
1018 file is lib/silcclient/command_reply.c, and
1019 lib/silcclient/idlist.[ch].
1021 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1023 * Do not send over 128 chars long nickname to the server
1024 in NICK command. Affected file lib/silcclient/command.c.
1026 * Do not send over 256 chars long channel names to the server
1027 in JOIN command. Affected file lib/silcclient/command.c.
1029 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1031 * Assure that silc_server_close_connection cannot be called
1032 twice for same socket context. Affected file is
1035 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1037 * Send error message to application if opening file for
1038 writing during file transfer fails. Affected file is
1039 lib/silcclient/client_ftp.c.
1041 Remove all file transfer sessions for a client that we're
1042 removing from ID cache.
1044 Affected file is lib/silcclient/client_ftp.c.
1046 * Fixed silc_net_addr2bin to return correct address. Affected
1047 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1049 * Fixed file transfer session removing on signoff notify.
1050 Affected file irssi/src/silc/core/silc-servers.c.
1052 * Added the SilcClientFileError to be returned in the monitor
1053 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1054 Affected file lib/silcclient/silcapi.h.
1056 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * Fixed a crash in silc_client_ftp_free_sessions and
1059 silc_client_ftp_session_free_client. Affected file
1060 lib/silcclient/client_ftp.c.
1062 * Added `disabled' field in the SilcChannelEntry in the server
1063 to indicate if the server entry is disabled. Affected file
1064 silcd/idlist.h, silcd/command[_reply].c.
1066 * SILC server adds now /var/run/silcd.pid everytime it is
1067 started. Affected file silcd/silcd.c.
1069 * Added silc_server_packet_send_clients to send a packet to
1070 the provided table of client entries. Affected file
1071 silcd/packet_send.[ch].
1073 * Fixed a crash in client resolving in client_prvmsg.c in
1074 client library. Affected file lib/silcclient/client_prvmsg.c.
1076 * Do not actually remove the client directly from ID cache
1077 during SERVER_SIGNOFF, but invalidate it. This way we
1078 preserve the WHOWAS info for the client. Affected file
1079 silcd/server_util.c.
1081 * Fixed SERVER_SIGNOFF notify handling in the server. The
1082 server is now able to process incoming SERVER_SIGNOFF notify
1083 for a server that it doesn't even know about. It will remove
1084 the clients provided in the notify. Affected file
1085 silcd/packet_receive.c.
1087 * Check for partial packet in data queue after every packet that
1088 was found from the queue. Return and wait for more data if
1089 there is partial data in queue. Affected file is
1090 lib/silccore/silcpacket.c.
1092 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1094 * Added SilcClietFileError enum to indicate error in
1095 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

1098 lib/silcclient/client_ftp.c.
1100 * Check that newsize in silc_buffer_realloc is larger than
1101 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1103 * Added better monitor of file transfers. It now monitors
1104 key agreement protocol during the file transfer too. Added
1105 error reporting too. Affected files
1106 irssi/src/silc/core/silc-servers.c,
1107 irssi/src/fe-common/silc/module-formats.[ch].
1109 * Wrote a help file for FILE command.
1111 * Added silc_rng_global_get_byte_fast to get not-so-secure
1112 random data as fast as possible. Random data is read from
1113 /dev/urandom if available and from the SILC RNG if not
1114 available. It is used in padding generation. Affected file
1115 lib/silccrypt/silcrng.[ch].

1128 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1130 * Assure that silc_client_notify_by_server_resolve does not
1131 resolve the client information multiple times. If it cannot
1132 be found by the first it cannot be found at all. Affected
1133 file lib/silcclient/client_notify.c.
1135 * Fixed WHOWAS command reply calling. Affected file
1136 lib/silcclient/command_reply.c.
1138 * Removed all references to silc_idlist_get_client from the
1139 Irssi SILC client since that call is internal call used by
1140 the library. The Irssi SILC client will use now client
1141 retrieval functions found in silcapi.h.
1143 * Fixed a bug in resolving nickname info before sending
1144 private message. It used freed memory. Affected file
1145 irssi/src/silc/core/silc-servers.c.

1166 * Added silc_net_localip to return local host's IP address.
1167 Affected file lib/silcutil/silcnet.[ch].
1169 * If key exchange or rekey protocol is active for a connection
1170 parse all packets syncronously since there might be packets
1171 in packet queue that we are not able to process without first
1172 processing packets before them. Affected file silcd/server,
1173 lib/silcclient/client.c.
1175 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1176 whether library should continue processing the packet.
1177 Affected file lib/silccore/silcpacket.h.

1223 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1224 is incomplete and is being resolved, it won't be resolved
1227 Make sure also that USERS command reply does not resolve
1228 twice information. Affected file is
1229 lib/silcclient/command_reply.c.
1231 Make sure that silc_client_get_clients_by_list does not
1232 resolve twice same information.
1234 * Check for valid client->id in the silc_server_free_client_data.
1235 Affected file silcd/server.c.
1237 * Fixed /GETKEY nick@server not to crash if the server entry
1238 is not found. Affected file lib/silcclient/command.c.

1246 Affected file silcd/command.c.
1248 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1250 * Call the silc_server_udpate_servers_by_server in the
1251 primary router that comes back online in the backup resuming
1252 protocol. Otherwise it routes packets wrong. Affected file
1253 silcd/server_util.[ch], silcd/server_backup.c.
1255 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1258 lib/silcutil/silcbuffmt.[ch].
1260 * Redefined the SILC packet header to include the padding
1261 length. Affected file lib/silccore/silcpacket.[ch].
1263 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1264 length for maximum padding up to 128 bytes). Affected
1265 file lib/silccore/silcpacket.h.
1267 * Removed all backwards support for old 0.5.x MAC thingies.
1268 The SILC packet header change makes it impossible to be
1269 backwards compatible.
1271 * Send the ENDING packet with timeout in the backup resuming
1272 protocol. This is to assure that all routers has connected
1273 to the primary router. Affected file silcd/server_backup.c.
1275 * Changed the RNG to take the first IV from random data. It
1276 used to take it from zero actually. Changed the RNG also
1277 to use /dev/urandom during session. /dev/random is used
1278 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1280 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1282 * Changed the SILC packet header to have the first two bytes
1283 (the packet length) encrypted. Affected files aroung the
1284 code tree, lib/silccore/silcpacket.[ch]. Removed the
1285 SilcPacketCheckDecrypt callback. It is not needed anymore
1286 since the silc_packet_receive_process will determine now
1287 whether the packet is normal or special.
1289 * Implemented the unidirectional MAC keys. Affected files
1290 lib/silcske/silcske.c, silcd/protocol.c and
1291 lib/silcclient/protocol.c.
1293 * Implemented the packet sequence number to the MAC computation.
1294 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1295 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1296 lib/silcclient/protocol.c.
1298 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1300 * Allow backup router to announce servers. All servers
1301 announced by backup router are added to the global list
1302 automatically. Update hte server's socket to our primary
1303 router also when backup router announces a server.
1304 Affected file silcd/packet_receive.c.
1306 * Do not update the client->router in the function
1307 silc_server_udpate_clients_by_server if the client is on
1308 global list. We might fail to find any specific server
1309 for locally connected clients and local cell clients. They
1310 should still use the `from' and not `to' as client->router.
1311 This fixes backup router resuming protocol. Affected file
1312 silcd/server_util.c.
1314 * Decrease channel statistics count only if the channel
1315 deletion worked. Affected files are silcd/server.c and
1316 silcd/server_util.c.
1318 * Added silc_server_update_servers_by_server to update origin
1319 of all server entries. Used during backup router protocol.
1320 Affected files silcd/server_util.[ch], silcd/server.c. and
1321 silcd/backup_router.c.
1323 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1324 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1325 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1326 lib/silccrypt/silchmac.c.
1328 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1330 * Assure that router cannot reroute the same channel message
1331 to the sender. Affected file silcd/packet_receive.c.
1333 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1335 * Made better checks that the channel message is not sent
1336 to the router it came from. Affected file is
1337 silcd/packet_send.c. Fixed memory leak too.
1339 * Announce informations for incoming router connection, but
1340 only after checking if it is replaced by backup router.
1341 Affected file silcd/packet_receive.c.
1343 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Fixed the backup resuming protocol to work in multiple
1346 router environment. Affected file silcd/server_backup.c.
1348 * Route packet only to one router in the function
1349 silc_server_packet_send_to_channel. Affected file is
1350 silcd/packet_send.c.
1352 * Fixed silc_server_send_notify_dest to set the broadcast
1353 flag. Fixed the silc_server_send_notify_topic to actually
1354 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1355 Affected file silcd/packet_send.c.
1357 * Changed the SFTP Filesystem interface. Changed the
1358 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1359 the filesystem operation function. The SilcSFTPFilesystem
1360 is now a context that is allocated by all filesystem allocation
1361 functions and it already includes the operations structure
1362 and filesystem specific context. It is given as argument
1363 now to the silc_sftp_server_start. This made the interface
1364 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1365 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1367 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1369 * Changed the backup router adding and getting interfaces
1370 in the server. The router that will be replaced by the
1371 specified backup router is now sent as argument. Affected
1372 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1375 * Added silc_net_addr2bin_ne to return the binary form of
1376 the IP address in network byte order. Affected files
1377 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1379 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Check for existing server ID in silc_server_new_server
1382 and in silc_server_connect_to_router_final and remove the
1383 old entry if it exists. Affected file silcd/packet_receive.c,
1386 * Send the channel message always to only one router, either
1387 in upstream or downstream. Affected file is
1388 silcd/packet_send.c.
1390 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Wrote the definition of the backup resuming protocol to the
1393 protocol specification.
1395 * Removed one redundant channel key generation from normal
1396 server during joining procedure. Removed one redundant
1397 channel key sending from server to router during joining
1398 procedure. Affected file silcd/command.c.
1400 * Made minor bugfixes to the backup router resuming protocol.
1401 Affected file silcd/server_backup.c, server.c.

1406 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1409 * Implemented the backup resuming protocol that is used to
1410 resume the primary router position in the cell after the
1411 primary router comes back online. Affected files
1412 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1413 and silcd/server_util.[ch].
1415 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Sleep two (2) seconds after sending QUIT command to server.
1418 Affected file lib/silcclient/command.c.
1420 * Assure that if outgoing data buffer is pending do not force
1421 send any data. Affected file silcd/packet_send.c.
1423 * Assure that if outgoing data buffer is pending do not force
1424 send any data. Affected file lib/silcclient/client.c.
1426 * Implemented the backup router support when the primary router
1427 goes down. The servers and routers can now use the backup
1428 router as new primary router without loosing connectivity.
1430 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1433 in the server to indicate disabled entry. All data read
1434 from the connection will be ignored and no data is sent
1435 for entry that is disabled. Affected files are
1436 silcd/idlist.h, silcd/server.c.
1438 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * Created SFTP client and server test programs in the
1441 lib/silcsftp/tests directory.
1443 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * Implemented memory filesystem (virtual filesystem) for
1446 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1449 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Implemented the SFTP (SSH File Transfer Protocol) to the
1452 lib/silcsftp. It includes SFTP client and SFTP server
1455 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Moved lib/silccore/silcprotocol.[ch] to the
1458 lib/silcutil library.
1460 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1461 take variable argument list pointer as argument. Affected
1462 file lib/silcutil/silcbuffmt.[ch].
1464 * Added silc_buffer_set function that is used to set data
1465 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1466 Affected file lib/silcutil/silcbuffer.h.
1468 * Changed various routines in the core library to use the new
1469 silc_buffer_set instead of allocating new buffer only for
1472 * Added 64-bit value formatting and unformatting support to the
1473 silc_buffer_[un]format routines. Affected file is
1474 lib/silcutil/silcbuffmt.[ch].
1476 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1477 to includes/bitmove.h.
1479 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1481 * Fixed channel user mode saving in client library. Affected
1482 file lib/silcclient/command[_reply].c.
1484 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1486 * Defined the file transfer to the SILC Protocol. Added
1487 new packet type SILC_PACKET_FTP and defined File Transfer
1488 Payload. The mandatory file transfer protocol is SFTP
1489 (SSH File Transfer Protocol). Affected file in addition
1490 of the internet draft is lib/silccore/silcpacket.h.
1492 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1493 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1494 is used as part of backup router protocol when the primary
1495 router of the cell is back online and wishes to resume
1496 the position as primary router.
1498 * Redefined the MAC generation keys in the protocol. The
1499 same key is not used anymore in both direction. Both
1500 direction will now use different keys for sending and
1501 receiving. This fixes a potential security flaw. This
1502 change causes incompatibilities in the protocol.
1504 * Redefined also the MAC computation from the packet.
1505 An packet sequence number is now added to the MAC
1506 computation. This prevents possible replay attacks against
1507 the protocol. This change too causes incompatibilities
1510 Added `sequence' field to the SilcPacketContext to hold
1511 the current sequence number for the packet.
1513 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1515 * Added `created' field to the SilcIDListData in the file
1516 silcd/idlist.h to indicate the time when the entry was
1519 * Added `created' field to the SilcChannelEntry too. Affected
1520 file silcd/idlist.h.
1522 * Added `creation_time' aguments to all the announcement functions
1523 in the server. If it is provided then only the entries that
1524 was created after the provided time frame are actually
1525 announced. Affected file silcd/server.[ch].
1527 * The protocol says that the Channel ID's IP address must be
1528 based on the router's IP address. Added check for this in
1529 the silc_server_new_channel when processing incoming New Channel
1530 Payload. Affected file silcd/packet_receive.c.
1532 * Print out the correct version with --version in SILC client.
1533 Affected file irssi/src/silc/core/silc-core.c.
1535 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * Fixed WHOWAS command to check for completnes of the client
1538 entry always, not just when the command is coming from client.
1539 Affected file silcd/command.c.
1541 * Added new function silc_server_packet_queue_purge to purge the
1542 outgoing data queue to the network. After the function returns
1543 it is guaranteed that the outgoing packet queue is empty.
1544 Affected file silcd/packet_send.[ch].
1546 * Purge the outgoing packet queue in the rekey protocol's final
1547 callback to assure that all rekey packets go to the network
1548 before quitting the protocol. Affected file silcd/server.c.
1550 * Added silc_client_packet_queue_parse as similar function as
1551 in server to the client library. The affected file is
1552 lib/silcclient/client.c.
1554 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1556 * Splitted silcd/server.c and created silcd/server_util.[ch]
1557 for utility functions.
1559 * Added new socket flag SILC_SF_DISABLED to indicate that the
1560 connection is open but nothing can be sent to or received from
1561 the connection. Affected file lib/silcutil/silsockconn.[ch].
1562 The checking for disabled socket is checked in the low level
1563 silc_socket_write and silc_socket_read functions.
1565 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Allow only nicknames and channel names that fits into the
1568 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1570 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * When processing JOIN command reply in server check that if
1573 the channel exists in our global list we'll move it the local
1574 list. Affected file silcd/command_reply.c.
1576 * Fixed the check whether client is joined on the channel already
1577 in JOIN command. Affected file lib/silcclient/command.c.
1579 * Fixed the JOIN command reply to check whether the channel
1580 already exists. Affected file lib/silcclient/command_reply.c.
1582 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Added silc_ske_status_string to map the SKE error numbers
1585 to readable strings. The affected files are
1586 lib/silcske/silcske[_status].[ch].
1588 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1590 * Do not show the private channels on the WHOIS channel list
1591 as it is not allowed by the protocol. The affected file is
1594 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1596 * Assure that the packet length digged from the actual packet
1597 is something sensible in the silc_packet_decrypt_rest_special
1598 in lib/silccrypt/silcpacket.c.
1600 * Free and NULL the allocated pointer in silc_hmac_alloc if
1601 the HMAC allocation fails. The affected file is
1602 lib/silccrypt/silchmac.c.
1604 * Print the selected security properties to the log files in
1605 the server. Affected file silcd/protocol.c.
1607 * Add SKE's reference counter even if calling the completion
1608 callback manually. Otherwise it goes negative, although it
1609 does not cause any problems. The affected file is
1610 lib/silcske/silcske.c.
1612 * Remove the client entry with short timeout after giving the
1613 KILL command. Affected file lib/silcclient/command.c.
1615 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1616 case all found clients are already disconnected (WHOWAS would
1617 found them) in the server. Affected file silcd/command.c.
1619 * Update the last_receive (time of last data received) to be
1620 updated only when received private or channel message so that
1621 the idle time showed in WHOIS makes more sense.
1623 * Added boolean field `valid' in to the SilcClientEntry in the
1624 client library to indicate whether the entry is valid or not.
1625 This fixes the nickname change bug on channel when changing
1626 the nickname to be same than the old (like nick to Nick) the
1627 nickname formatter doesn't set the new nick anymore to Nick@host.
1628 Affected file lib/silcclient/idlist.[ch].
1630 * Now actually fixed the nickname changing on disconnection.
1631 Added new function silc_change_nick to the Irssi SILC Client.
1632 Affected file irssi/src/silc/core/client_ops.c,
1633 irssi/src/silc/core/silc-nicklist.[ch].

1637 * Check that the public key exists in the GETKEY command before
1638 trying to encode it. Affected file silcd/command.c.
1640 * Print some notifications on received public keys with GETKEY
1641 command in the Irssi SILC Client. Affected files are
1642 irssi/src/fe-common/silc/module-formats.[ch],
1643 irssi/src/silc/core/client_ops.c.
1645 * Use IDENTIFY command to resolve the server information in the
1646 GETKEY command instead of INFO command. Affected file
1647 lib/silcclient/command.c.
1649 * All command reply functions in the client library now calls
1650 the pending command reply callbacks even if an error has
1651 occurred. The server has done this a long time and now it was
1652 time to move the client library to this as well. Now all
1653 errors can be delivered back to the pending command reply
1654 callbacks if necessary. Affected files are
1655 lib/silcclient/command[_reply].[ch].
1657 * Change the nickname on disconnection back to the username
1658 because in reconnect the server will enforce it to it anyway.
1659 Affected file irssi/src/silc/core/silc-servers.c.
1661 * Fixed a config file parsing bug in the Irssi SILC client.
1662 Affected file irssi/src/silc/core/clientconfig.c.
1664 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1666 * When printing the channel mode on JOIN, verify that the
1667 channel key and channel's HMAC are valid. Affected file
1668 irssi/src/silc/core/client_ops.c.
1670 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1672 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1673 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1674 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1676 * Removed channel key rekey task deleting from the function
1677 silc_server_save_channel_key. Affected file silcd/server.c.
1678 Added explicit timeout task context instead that is used to
1679 delete the task if we are registering a new task before the
1680 new task has elapsed.
1682 * When channel key rekey occurs the client library now saves
1683 the old channel key for a short period of time (10 seconds) and
1684 is able to use it in case some is still sending channel
1685 messages encrypted with the old key after the rekey. Affected
1686 file lib/silcclient/[idlist.h|client_channel.c].
1688 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1690 * Added check to the silc_server_new_id_real to not accept
1691 new ID if it is the sender's own ID. Affected file is
1692 silcd/packet_receive.c.
1694 * Assure that we do not announce ourself or the one we've
1695 sending our announcements when we're router and are announcing
1696 servers to our primary router. Affected file silcd/server.c.
1698 * Fixed silc_server_command_identify_check_client to assemble
1699 correct WHOIS packet. It send corrupted WHOIS packet and
1700 caused problem with router to router connections. Affected
1701 file silcd/command.c.
1703 Fixed also silc_server_command_whois_check the same way
1704 as for the IDENTIFY command.
1706 * Added new SilcIDListStatus to the server in the SilcIDListData
1707 structure. The status now includes the current status of
1708 the entry (like registered, resolved etc.). Affected file
1709 silcd/idlist.[ch]. Defined a bunch of different status types
1710 as well. This replaced the old boolean registered field as well.
1712 Added resolve_cmd_ident field to the SilcClientEntry structure
1713 too so that if the entry is for example being resolved so
1714 another command may attach to the same pending command reply
1715 without requiring to resolve the same entry again. This concept
1716 should optimize the WHOIS and the IDENTIFY resolving under
1717 heavy load by taking away unnecessary resolving for entries
1718 that are being resolved already.
1720 Added support for adding multiple pending commands for one
1721 command idenfier. Affected file silcd/command[_reply].[ch].
1723 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1724 before deleting the data. Otherwise the hash table will have
1725 freed data in comparison functions. Affected file is
1726 silcd/command_reply.c.
1728 * Fixed silc_idlist_replace_client_id to add the new entry to
1729 the cache with NULL nickname. Otherwise there will be invalid
1730 memory as the nickname after the nickname is freed. Affected
1731 file silcd/packet_receive.c.
1733 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1734 saved into wrong slots because the previous number of entries
1735 was not taken into account. Affected file silcd/idlist.c.
1736 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1738 * If we are router and we receive JOIN notify to a channel that
1739 does not have any users then notified client is marked as the
1740 channel founder, as it is it. The affected file is
1741 silcd/packet_receive.c
1743 * Added to the extended hash table API's table_del_*ext functions
1744 the destructor as argument too, so that the caller can decide
1745 which destructor to use or whether to use destructor at all.
1746 Affected file lib/silcutil/silchashtable.[ch].
1748 * Fixed ID Cache purging. It actually deleted the entries from
1749 the hash table after the data was freed. The hash table ended
1750 up comparing freed memory. The affected file is
1751 lib/silccore/silcidcache.c.
1753 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Fixed Irssi SILC client's KILL command's HELP syntax.
1757 * The USERS command now resolves the detailed user information
1758 if the userinfo field is missing. Affected file is
1759 lib/silcclient/command_reply.c.
1761 * Do not print error in silc_file_read if the read file does
1762 not exist. Just silently return NULL. Affected file is
1763 lib/silcutil/silcutil.c.
1765 * Fixed the silc_log_output to not wine about NULL filename
1766 and to not create some bogus " " filename. Affected file is
1767 lib/silcutil/silclog.c.
1769 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1771 * Fixed various printing bugs on the user interface in the
1772 Irssi SILC Client. Minor changes that were forgotten from
1775 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * Fixed the configure.in.pre and the compilation and distribution
1778 environment to support the new autoconf 2.52. That version is
1779 now required to compile the CVS trunk.
1781 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1784 to generally parse user@fqdn format strings. Affected file
1785 lib/silcutil/silcutil.c.
1787 * Added nickname_format and nickname_force_format fields to the
1788 SilcClientParams structure. The first one defines the format
1789 for the nicknames that the library will enforce if the receives
1790 multiple same nicknames. The second one is boolean value and
1791 can be used to force the library to always enforce the format
1792 to the nicknames regardles whether there are multiple nicknames
1793 or not. This configurable formatting was employed to flexibly
1794 support accessing multiple nicknames from the user interface.
1795 The userinterface can now set the nicknames to what ever format
1796 they prefer. Affected file lib/silcclient/silcapi.h.
1798 Added function silc_client_nickname_format to the file
1799 lib/silcclient/idlist.c. It performs the nickname formatting.
1801 Added new field `hostname´ to the SilcClientEntry context.
1802 It holds the hostname of the client. Affected file is
1803 lib/silcclient/idlist.h.
1805 * Irssi SILC Client sets the nicknames in nick@hostn format.
1806 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1807 irssi/src/silc/core/silc-core.c.
1809 The WHOIS printing now also shows both the real nickname and
1810 the formatted nickname so that user knows how to access the
1811 user if there are multiple same nicknames cached. Affected
1812 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1813 printing formatting too to take the hostname now as a separate
1814 argument. The Affected file is
1815 irssi/src/fe-common/silc/modules-formats.[ch].
1817 * Changed the silc_client_get_clients_local to accept the formatted
1818 nickname as argument. It accepts the real nickname too but the
1819 formatted nickname can be used to find the true entry from
1820 multiple entries. Affected file lib/silcclient/silcapi.h and
1821 lib/silcclient/idlist.c.
1823 * Added nickname_format_parse field to the SilcClientParams.
1824 It is a callback function provided by the application to parse
1825 the nickname out of the formatted nickname string. The library
1826 calls it to get the nickname from the formatted string. Since
1827 the application generally knows better the format of the nickname
1828 string it parses it instead of the library, even though library
1829 encodes the formatted string. If the callback function is not
1830 provided then the library will use the string as is. The
1831 affected file is lib/silcclient/silcapi.h.
1833 * All the nickname strings passed to the client library in
1834 commands are now expected to be formatted nickname strings.
1835 If the command does not support the formatted nickname string
1836 it will assume that the sent string is the actual nickname.
1837 Affected file lib/silcclient/command.c.
1839 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * Added public key authentication support to OPER and SILCOPER
1842 commands in the client library. Affected file is
1843 lib/silcclient/command.c.
1845 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1847 * Changed the get_auth_methdod client operation to be asynchronous.
1848 It can be async if the application resolves the authentication
1849 method from the server during the negotiation. Added new
1850 SilcGetAuthMeth completion callback that the application will
1851 call after resolving the authentication method.
1853 Added function silc_client_request_authentication_method that
1854 the application can use to resolve the authentication method
1855 from the server. Added also SilcConnectionAuthRequest callback
1856 that the library will call after the server has replied. The
1857 application can call this function if it does not know the
1858 current authentication method.
1860 Affected files are lib/silcclient/client.c and
1861 lib/silcclient/silcapi.h.
1863 * The Irssi SILC client now automatically resolves the authentication
1864 method incase any configuration information is not present (and
1865 currently there never is). The affected file is
1866 irssi/src/silc/core/client_ops.c.
1868 * Fixed public key authentication from the client library.
1869 Affected file lib/silcclient/protocol.c. Changed also the
1870 protocol specification about the public key authentication in
1871 the connection authentication protocol. The actual data to be
1872 signed is now computed with a hash function before signing.
1874 * Fixed the public key authentication from the server as well.
1875 Affected file silcd/protocol.c.
1877 * Removed the mlock()'s from the memory allocation routines.
1878 Affected file lib/silcutil/silcmemory.c. The ./configure does
1879 not check anymore for the mlock(). Affected file is
1882 * Fixed USERS command in server to allow the execution of the
1883 command for private and secret channels if the client sending
1884 the command is on the channel. Affected file silcd/command.c.
1886 * Fixed silc_client_get_clients_local to return the clients
1887 count correctly. It could return wrong value. Affected file
1888 lib/silcclient/idlist.c.
1890 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1893 types. The assembler optimizations seemed not to like 64-bit
1894 data types. The assmebler optimizations thus are now enabled
1895 also for BSD systems as opposed to only enable them for Linux.
1897 * Do not check for threads at all on BSD systems. Affected
1898 file configure.in.pre.
1900 * Removed -n and -h options from the Irssi SILC Client since
1901 they are not used in silc.
1903 * Fixed the prime generation to assure that the first digit
1904 of the generated random number is not zero since our conversion
1905 routines does not like number strings that starts with zero
1906 digit. If zero digit is seen the random number is regenerated.
1907 This caused some corrupted RSA keys when the zero first digit
1908 was met. Affected file lib/silcmath/silcprimegen.c.
1910 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1912 * Fixed WIN32 configuration in the ./configure script.
1913 Fixed to include xti.h on environments that has it.
1914 Patches by Carsten Ilchmann and andrew.
1916 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Changed the silc_id_create_client_id to be collision
1919 resistant. It is now assured that there cannot be created
1920 two same client ID's. I suspect that some weird bugs in
1921 the server were actually caused by duplicate Client IDs.
1922 Affected file silcd/serverid.[ch]. A router receiving
1923 new ID now also assures and informs the sending server
1924 if the ID caused collision.
1926 * Changed the silc_id_create_channel_id to also assure that
1927 there are no collisions.
1929 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Statement about ignoring the Mutual Authentication flag when
1932 performing rekey with PFS was a bit misleading. It is ignored
1933 if it was set in the initial negotiation, it cannot be even
1934 set in the rekey. Fixed in the ke-auth draft. Started the
1935 new versions of the protocol drafts in the doc/.
1937 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * Fixed a bug in silc_client_command_identify_save when saving
1940 new channel information. The channel name was no duplicated
1941 and caused crash on exit. Affected file is
1942 lib/silcclient/command_reply.c.
1944 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Fixed the getkey command handling in the server. Send just
1947 empty OK reply to the sender if the key could not be fetched
1948 (but everything else was ok, like the key just was not available).
1949 Changed the public key parameter to optional in the protocol
1950 specs so that empty OK reply can be sent. Affected file
1953 Added a message to Irssi SILC client to tell to user if the
1954 server did not return a public key.
1956 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * Fixed a channel key regeneration bug. It registered new
1959 timeout tasks exponentially until all system resources were
1960 used. Affected file silcd/server.c.
1962 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Added the SILC Document generator to the scripts/silcdoc.
1965 It can be used to generate the Toolkit Reference Manual out
1966 of the source tree. Internally it will also use the RoboDoc
1967 generator now imported in util/robodoc.
1969 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * Added couple of return's in rekey protocol if error orccurred
1972 during the protocol. The execution must be terminated.
1973 Affected file silcd/protocol.c. Also, terminate the protocol
1974 always with timeout.
1976 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1978 * The client's Client ID was created initally from the wrong
1979 nickname (it could have been in format nick@host) in the
1980 silc_server_new_client. Affected file silcd/packet_receive.c
1982 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1984 * Added some SILC_LOG_ERROR's to various error conditions
1985 if client could not be added to ID cache. Affected files
1986 silcd/packet_receive.c and silcd/server.c.
1988 * When client's sock->user_data is freed, NULL also the
1989 client->router and client->connection pointers. Added check
1990 for these pointers being NULL to various places around the
1991 code. Affected file silcd/server.c.
1993 * Added client->data.registered == TRUE checks to various
1994 places around the code to assure that unregistered client's
1995 are not handled when it is not allowed. Affected file
1998 * Added `bool registered' fields to all
1999 silc_idlist_[server|client]_get_* routines to indicate whether
2000 the fetched client needs to be registered or not. Affected
2001 file silcd/idlist.[ch].
2003 * Add your own entry as registered to the ID cache in the
2004 server. Affected file server.c.
2006 * Fixed a bug in silc_server_new_server. The SilcServer was
2007 set as the new server's context instead of SilcServerEntry.
2008 This naturally caused some weird bugs.
2010 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2012 * Do not delete the channel rekey task when adding it
2013 for in silc_server_create_channel_key.
2015 * Changed the silc_server_create_channel_key to return
2016 TRUE or FALSE to indicate the success of the channel key
2019 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2021 * Fixed MSVC++ project files and added missing files to
2022 Makefiles under win32/.
2024 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Do not add TCP_NODELAY flag if the operating system
2027 does not have it defined. Affected files are
2028 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2030 * Fixed buffer overflow from Irssi SILC Client. Affected
2031 file irssi/src/fe-common/core/themes.c.
2033 * Fixed double free in client library in the file
2034 lib/silcclient/client.c when disconnecting from server.
2036 * Applied double free patch from cras to Irssi SILC client.
2037 Affected files irssi/src/core/[modules/expandos].c
2039 * Fixed the disconnection handling to Irssi SILC Client.
2040 The application must call silc_client_close_connection
2041 in ops->connect client operation in case of failure of
2042 the connection. Affected file is
2043 irssi/src/silc/core/client_ops.c.
2045 * Do not set sock->protocol to NULL in the function
2046 silc_client_close_connection after executing the protocol's
2047 final callback since the sock might not be valid anymore.
2048 Affected file lib/silcclient/client.c.
2050 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2052 * Do not enable SILC_THREADS if the linking with libpthread
2053 did not happen. Affected file configure.in.pre.
2055 * Added notion to protocol specification that server must
2056 verify the sent authentication payload with CMODE when
2057 setting the channel founder key. Implemented it to the
2058 server. Affected file silcd/command.c.
2060 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * Added _EXTRA_DIST SILC distribution variable to the
2063 distributions file. It is used to conditionally add extra
2064 files or directories to the specific distribution. Affected
2065 files ./prepare, Makefile.am.pre and distributions.
2067 Removed the `_' from the start of the distribution names.
2070 * Added README.WIN32 for instructions to compile the Toolkit
2073 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2075 * Fixed a double free in disconnection in the server. Affected
2076 file is silcd/server.c.
2078 * Fixed the lib/silcske/groups.c to work now also with GMP
2079 MP library. The string conversion did not work when using
2080 specific base and the base is indicated in the string as well.
2082 * Created win32/ directory which now includes MSVC++ specific
2083 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2084 It will appear only in the toolkit distribution
2086 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2088 * Changed the key material distribution function in case when
2089 the hash output is too short. The data is now concatenated
2090 a bit differently than it used to. Made the change to the
2091 SKE protocol specification.
2093 * Added better GMP detection to configure.in.pre. A patch
2096 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Fixed a minor bug in SKE that might cause some problem on
2099 some platforms. Affected file lib/silcske/silcske.c.
2101 * Added the cookie checking for initiator in the SKE. It checks
2102 that the responder returns the sent cookie unmodified. The
2103 affected file is lib/silcske/silcske.c. Added new SKE
2104 error type INVALID_COOKIE that can be sent during the
2105 negotiation. Fixed some memory leaks as well.
2107 * Added the "invalid cookie" error message to Irssi SILC client's
2110 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Added `task_max' field to the SilcClientParams to indicate
2113 the maximum tasks the scheduler can handle. If set to zero,
2114 default values are used. Affected file lib/silcclient/silcapi.h.
2116 * Fixed memory leaks in silc_client_close_connection. Affected
2117 file lib/silcclient/client.c.
2119 * Added silc_client_del_client_entry to client library to free
2120 all memory of given client entry. Affected file is
2121 lib/silcclient/idlist.[ch].
2123 * Added new functions silc_client_del_channel and
2124 silc_client_del_server to delete channel and server entries.
2125 Affected file lib/silcclient/[silcapi.h/idlist.c].
2127 * Removed silc_client_del_client_by_id from silcapi.h.
2129 * Fixed the INFO command to return the server's own info
2130 correctly when querying by Server ID. Affected file is
2133 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2135 * Removed the non-blocking settings in WIN32 code in the
2136 silc_sock_[read/write] and added SleepEx instead. Affected
2137 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2138 of input data is now checked with FIONREAD and ioctlsocket.
2140 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2142 * Call silc_schedule_task_del_by_context in the
2143 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2144 Affected file lib/silccore/silcprotocol.c.
2146 * Call silc_protocol_cancel for active protocols in the
2147 silc_server_close_connection if the funtion
2148 silc_server_free_sock_user_data has not been called.
2149 Affected file silcd/server.c.
2151 * Generic tasks cannot be deleted using the del_by_fd
2152 task deleting function since generic tasks does not match
2153 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2155 * Added a notion to SILCOPER help file that the SILCOPER works
2156 only on router server, not on normal server.
2158 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2160 * Added for WIN32 support for the new scheduler as well.
2161 Affected file lib/silcutil/win32/silcwin32schedule.c.
2163 * Fixed the SHA1 implementation to work on various platforms.
2165 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2168 API. It is part of the scheduler now. Everything else is
2169 as previously but some functions has changed their names.
2170 Checkout the lib/silcutil/silcschedule.h for the interface.
2171 Updated all applications to use the new interface. Affected
2172 files are lib/silcutil/silcschedule.[ch].
2174 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2176 * Found a bug in the SKE implementation. The HASH value,
2177 specified by the protocol, was not computed correctly. The
2178 public key of the responder was not added to the computation
2179 even though it is mandatory. Affected file lib/silcske/silcske.c.
2180 This unfortunately causes incompatibilities with older
2181 clients and servers.
2183 * Added WIN32 specific network init and uninit functions:
2184 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2185 the Winsock2. Affected file lib/silcutil/silcnet.h and
2186 lib/silcutil/win32/silcwin32net.c.
2188 * Set the socket always to nonblocking mode on WIN32 after
2189 reading data or writing data. Affected file is
2190 lib/silcutil/win32/silcwin32sockconn.c.
2192 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2194 * Fixed various compilation problems under WIN32. Affected
2195 files lib/silcutil/win32/silcwin32thread.c and
2196 lib/silcutil/win32/silcwin32schedule.c.
2198 * Removed all _internal.h #includes from public header
2199 files. Internal headers must never be included from
2202 Removed also the lib/silcske/payload_internal.h file.
2204 * All include files that may be needed (public and some others
2205 included by the public headers) by application developers are
2206 now copied to the ./includes directory. It does not copy any
2207 internal headers. Affected file Makefile.defines.pre and all
2208 Makefile.am's under lib/ and subdirs.
2210 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * Do not change the ~/.silc directory's permissions automatically.
2213 Affected file irssi/src/silc/core/clientutil.c.
2215 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2217 * Do not cancel the protocol in silc_server_close_connection
2218 it might cause recursion. Now cancelled in the function
2219 silc_server_free_sock_user_data. Affected file silcd/server.c.
2221 * Fixed the silc_server_remove_clients_by_server to regenerate
2222 the channel keys correctly finally. Added also new function
2223 silc_server_remove_clients_channels to actually do it.
2224 Affected file silcd/server.c.
2226 * Fixed the silc_server_new_channel to not crash by giving
2227 wrong router to the new channel. Affected file is
2228 silcd/packet_receive.c.
2230 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2232 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2233 which is given as argument to the silc_client_alloc now.
2234 It can be used to configure the client and set various parameters
2235 that affect the function of the client.
2237 * The USERS command in server did not check whether the channel
2238 is private or secret. Affected file silcd/command.c.
2240 * Added new argument to the USERS command in protocol specification.
2241 The USERS command now can take the channel name as argument
2242 as well. Added support for this in client and server and
2243 updated the protocol specs.
2245 * Completed the GETKEY command in client. It can be now used
2246 to fetch also servers public key not only some clients.
2247 Affected files lib/silcclient/command[_reply].c.
2249 * Added silc_client_get_server to return server entry by the
2250 server name. Affected files lib/silcclient/silcapi.h and
2253 * Redefined the IDENTIFY command in protocol specification to be
2254 more generic. It now can be used to query information about
2255 any entity in the SILC Network, including clients, servers and
2256 channels. The query may be based either the entity's name
2257 or the ID. Added support for this in both client and server.
2259 Affected files silcd/command.c and lib/silcclient/command.c
2260 and command_reply.c.
2262 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2263 the _from_client and _from_server functions. Affected file
2266 * Added silc_client_get_channel_by_id_resolve to the file
2267 lib/silcclient/silcapi.h to resolve channel information by
2268 its ID. Added also silc_client_get_channel_by_id that
2269 does not resolve it from the server.
2271 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Added SilcServerEntry context into the client library
2274 to represent one server. The INFO command now allocates
2275 these to save the resolved server info. For now on the
2276 client library will also keep information about servers,
2277 connected and resolved with INFO.
2279 The INFO command now allocates the SilcServerEntry context
2280 and saves the server info there. The COMMAND_REPLY in
2281 the INFO now returns the parameters to application in
2282 same order as defined in the protocol specification.
2284 The entries are cached in the client->server_cache.
2286 * The INFO command is now issued after received the Client ID
2287 from the server. Affected file lib/silcclient/client.c.
2289 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2290 to the application as the mode changer might be server.
2291 It is guaranteed that NULL is not returned anymore to the
2292 application. Affected file lib/silcclient/client_notify.c.
2294 The ID Type is now also passed to the application so that
2295 it can check whether the returned entry is SilcClientEntry
2298 Added new function silc_client_get_server_by_id to return
2299 the server entry by ID. Affected files are the
2300 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2302 * Do not create the channel in the Irssi SILC Client when issuing
2303 the JOIN command but when received the sucessful JOIN command
2304 reply. Otherwise the channel might get created even though we
2305 could not join it. The Affected file is
2306 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2308 * Fixed a channel joining bug in router. The router must also
2309 check the channel modes, invite and ban lists etc. when serving
2310 the JOIN command sent by normal server. Affected file is
2311 silcd/command.c. The router now resolves the client's
2312 information from the server who sent the JOIN command if it
2313 does not know it, and processes the JOIN command only after
2316 * Changed the SilcCommandCb to take new argument; void *context2.
2317 Affected file lib/silccore/silccommand.h
2319 The second argument in the command callbacks in the server now
2320 includes the SilcServerCommandReplyContext if the command was
2321 called as pending command callback from the command reply.
2322 Otherwise it is NULL. When called as pending the status of the
2323 command reply will be checked and if it was erronous the
2324 error will be sent to the original sender of the command.
2325 This way the client always receives the error messages even
2326 though the server was actually the one who received the error
2327 when it resent the command to router, for example. Affected
2328 files silcd/command[_reply].[ch].
2330 * Fixed sending WHOWAS command's error message to client if
2331 the requested client could not be found. It was missing.
2334 * Changed the CMODE and CUMODE commands reply arguments in the
2335 protocol specification. The Channel ID is now sent in both
2336 of the commands to identify the channel. Implemented this
2337 new feature to the client and server. Affected files
2338 lib/silcclient/command_reply.c and silcd/command.c.
2340 * Made better checks for invite and ban lists in the JOIN
2341 command in server. Affected file silcd/command.c.
2343 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * The server now performs the incoming host IP/DNS lookup
2346 using the silc_socket_host_lookup and thus does not block
2347 the server anymore. Affected file silcd/server.c.
2349 * Completed the multi-thread support for SILC Scheduler in
2350 the lib/silcutil/silcschedule.c.
2352 * Fixed the configure.in.pre to detect the pthread correctly
2355 * Fixed a deadlock in silc_task_queue_wakeup in the file
2356 lib/silcutil/silctask.c.
2358 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Added new function silc_schedule_wakeup that is used in
2361 multi-threaded environment to wakeup the main thread's
2362 schduler. It needs to be used when a thread adds a new task
2363 or removes a task from task queues. After waking up, the
2364 scheduler will detect the task queue changes. If threads
2365 support is not compiled in this function has no effect.
2366 Implemented the wakeup mechanism to both Unix and WIN32
2367 systems. Affected files are lib/silcutil/silcschedule.[ch],
2368 lib/silcutil/unix/silcunixschedule.c and the
2369 lib/silcutil/win32/silcwin32schedule.c.
2371 * Added new function silc_task_queue_wakeup to wakeup the
2372 scheduler by the specified task queue. Affected file
2373 lib/silcutil/silctask.[ch].
2375 * The silc_socket_host_lookup_start now wakes up the scheduler
2376 after adding the timeout task. Affected file is
2377 lib/silcutil/silcsockconn.c.
2379 * The silc_socket_host_lookup is synchronous now if the threads
2380 support is not compiled in. However, the callback is still
2381 called asyncronously through the scheduler, anyway. Affected
2382 file lib/silcutil/silcsockconn.c.
2384 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2386 * Added new function silc_socket_host_lookup to perform
2387 asynchronous IP and FQDN lookups for the socket connection.
2388 Affected files lib/silcutil/silcsockconn.[ch].
2390 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2392 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2393 that may or may not compile the mutex support in.
2395 Changed the silc_mutex_alloc interface. It allocates the
2396 mutex now to the sent pointer and returns TRUE or FALSE.
2398 Affected file lib/silcutil/silcmutex.h.
2400 * Wrote the SILC Task Queue interface to support multi-threads.
2401 Affected file lib/silcutil/silctask.[ch].
2403 * Wrote the SILC Scheduler to support multi-threads. Affected
2404 file lib/silcutil/silcschedule.c.
2406 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2409 in lib/silcutil/win32/.
2411 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Defined SILC Mutex API and SILC Thread API and implemented
2414 them for Unix. Affected files are
2415 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2416 lib/silcutil/unix/silcunixmutex.c and
2417 lib/silcutil/unix/silcunixthread.c.
2419 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2421 * Fixed the silc_server_remove_clients_by_server's channel
2422 key re-generation. The hash table handling was incorrect
2423 and would not work with many channels. Affected file is
2426 * Fixed some memory leaks around the server code.
2428 * Rewrote the silc_server_get_users_on_channel to support IPv6
2429 based Client ID's. Affected file silcd/server.c.
2431 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2432 specification. However, a separate document must be written
2433 to define the detailed signing procedure and the payload
2434 associated with the flag. Defined the flag to the
2435 lib/silccore/silcchannel.h as well.
2437 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2439 * Changed the dynamic tables to static size tables in the
2440 lib/silccrypt/silchmac.c.
2442 * Removed GCC dependencies from the code. A patch by cras.
2444 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Do not show the error "Error receiving packet bla bla"
2447 in server if it really was not an error (-2 means that reading
2448 is pending). Affected file silcd/server.c.
2450 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Fixed a possible crash in silc_server_remove_clients_by_server
2453 in silcd/server.c. Fixed there also some memory leaks.
2455 * Fixed the silc_idlist_replace_client_id. It could replace
2456 wrong key in the hash table. Affected file silcd/idlist.c.
2458 * Do not check whether there are global users on the channel
2459 if the channel->global_users is FALSE. Affected functions
2460 silc_server_remove_from_one_channel and
2461 silc_server_remove_from_channels in silcd/server.c. Also,
2462 do not check if the removed client is local as we can be
2463 sure that global client was not removed from the channel
2464 and checking for global users is not needed.
2466 * The silc_server_remove_clients_by_server now re-generates
2467 the channel keys correctly for those channels that had
2468 clients removed from them. Affected file silcd/server.c.
2470 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * Found the reason of random crashes in the server. We weren't
2473 ignoring the SIGPIPE signal (which can be sent in write())
2474 and it crashed the server. Affected file silcd/silcd.c.
2476 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * Assure that sock->user_data is not NULL in the function
2479 silc_server_packet_send in silcd/packet_send.c.
2481 * Disconnect the remote connection if it could not be added
2482 to any ID lists in the server. The affected file is
2485 * Check in silc_server_packet_send[_real/dest] that the
2486 socket is not disconnecting and ignore the data if it is.
2487 Affected file silcd/packet_send.c.
2489 * Define inline to __inline on native WIN32 compilation.
2490 Affected file includes/silcwin32.h.
2492 * Added some explicit type casts for inline code since MSVC
2493 require them. Affected files lib/silcutil/silcbuffer.h,
2494 lib/trq/silcdlist.h and lib/trq/silclist.h.
2496 * Print warning in log files from now on if the packet
2497 decryption fails. Affected file silcd/server.c.
2499 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Changed the `say' client operation's interface to accept
2502 new `type' argument to indicate the type of the message sent
2503 by the library. The application may filter the library's
2504 messages according the type. The affected file is the
2505 lib/silcclient/silcapi.h.
2507 * Added two new functions to lib/silcclient/silcapi.h:
2508 silc_client_del_client and silc_client_del_client_by_id.
2509 Affected file lib/silcclient/idlist.c.
2511 * Moved the clientincludes.h from includes/ to silc/ and
2512 serverincludes.h from includes/ to silcd/.
2514 * The modes for the CMODE and CUMODE are now passed as
2515 uint32 for application with COMMAND_REPLY. The affected
2516 file is lib/silcclient/command_reply.c.
2518 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2520 * /WHOIS without arguments shows client's own information.
2521 Affected file lib/silcclient/command.c.
2523 * Changed PING to not accept any arguments. The specs
2524 says that client can ping only the connected server so
2525 requiring an argument is not needed. Affected file is
2526 lib/silcclient/command.c.
2528 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2530 * Fixed a fatal bug in private message sending and reception
2531 encryption and decryption when using private message keys.
2532 The implementation was incorrect and did not follow the
2533 specification. It causd that some of the message were
2534 lost since it did not use the sending and receiving keys
2535 as the protocol suggests. This has been fixed and will cause
2536 incompatibilities with older clients when sending private
2537 message encrypted with private message keys. Affected files
2538 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2539 and various other in Irssi SILC Client.
2541 Added `responder' boolean argument to the functions
2542 silc_client_add_private_message_key[_ske] to indicate when
2543 the key is added as responder or initiator of the key
2546 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2548 * Removed the silc_ske_check_version function and created
2549 a SilcSKECheckVersion callback. Added also a function
2550 silc_ske_set_callbacks that is now used to set all SKE
2551 callbacks. The callback functions are not given to
2552 the SKE functions anymore, but this function is used to
2555 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2557 * Added `silc_version' argument to the silc_client_alloc
2558 to define the version of the application for the library.
2559 The library will use the version string to compare it
2560 against the remote host's (usually a server) version
2561 string. Affected file lib/silcclient/silcapi.h
2563 * Added the KE protocol context to Key Agreement context
2564 in client library so that we can abort the SKE if it
2565 is in process when we get timeout. Affected file is
2566 lib/silcclient/client_keyagr.c.
2568 * Do not resolve the client ID forever if it returns in the
2569 first time that such client does not exist. This was done
2570 for example with private message. Affected file is
2571 lib/silcclient/client_prvmsg.c.
2573 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Do not add regex.h for WIN32. The affected file
2576 includes/silcincludes.h.
2578 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2579 not work yet 100%. It generates the DLL's automatically
2580 when compiling with --with-win32 under cygwin.
2582 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * lib/contrib/regex.c is not compiled on WIN32.
2586 * Added silc_net_get_socket_opt function to the
2587 lib/silcutil/silcnet.h.
2589 * Added includes/silcwin32.h for WIN32 specific includes
2592 * Do not use ptime structure or any of the posix process
2593 functions on WIN32 in lib/silccrypt/silrng.c.
2595 * Added silc_gettimeofday to provide generic function
2596 for struct timeval on all platforms. Added the function
2597 to lib/silcutil/silcutil.h.
2599 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2602 library as they clearly belong there. As a plus side we
2603 can make the actual socket connection routines platform
2606 Added also new generic function silc_socket_read and
2607 silc_socket_write (that used to be silc_packet_[read/write].
2608 The implementation of these are platform specific.
2610 * Added WIN32 specific routines of silc_socket_[read/write]
2611 to lib/silcutil/win32/silcwin32sockconn.c.
2613 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Added preliminary support for native WIN32 compilation under
2616 cygwin (using the -mno-cygwin option for GCC) to the
2617 ./configure.in.pre. The --with-win32 now prepares the
2618 compilation for native WIN32.
2620 * Rewrote the SILC Scheduler interface in the file
2621 lib/silcutil/silcschedule.h. The scheduler is now context
2622 based and does not have anymore any global static scheduler.
2623 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2624 and created lib/silcutil/win32 directory for WIN32 based
2627 * Added Unix specific network routines to the
2628 lib/silcutil/unix/silcunixnet.c and the old
2629 lib/silcutil/silcnet.c includes now only generic routines.
2631 Added WIN32 specific network routines to the
2632 lib/silcutil/win32/silcwin32net.c.
2634 * Added Unix specific utility functions from the
2635 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2637 * Added WIN32 SILC Scheduler to the file
2638 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2641 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2643 * Do not handle JOIN notify in the server if the target client
2644 is not registered (idata->registered == FALSE). The affected
2645 file is silcd/packet_receive.c.
2647 * Update the nickrec->founder in event_cumode in the Irssi SILC
2648 client. Affected file irssi/src/silc/core/silc-channels.c.
2650 * Fixed the CUMODE_CHANGE notify handling in the server when
2651 server and router are announcing their clients on channels.
2652 Now the mode changes are saved and notified correctly. The
2653 affected file is /silcd/packet_receive.c.
2655 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2656 They really did not replace the cache entry in the ID Cache.
2657 Now they do that. Affected file silcd/idlist.c.
2659 * Fixed the KICK notify handling in the Irssi SILC client to
2660 update the channel records so that the kicked client does not
2661 appear to be on the channel. The affected file is
2662 irssi/src/silc/core/silc-channels.c.
2664 * Always update the conn->current_channel when executing command
2665 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2667 * Fixed the KILL notify handling in Irssi SILC client to remove
2668 the killed client on all channels.
2670 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Fixed the silc_parse_command_line to remove extra spaces
2673 from the start and end of the arguments. Affected file is
2674 lib/silcutil/silcutil.c.
2676 * Cancel and free any active protocol in the function
2677 silc_server_close_connection. Affected file silcd/server.c.
2679 * Cancel and free any active protocol in the function
2680 silc_client_close_connction. Affected file is
2681 lib/silcclient/client.c.
2683 * Do not execute the KILL command for clients that are in
2684 history (ie. they are not in the network). Affected file is
2687 * Fixed KILL notify handling, client does not crash anymore.
2688 Affected file irssi/src/silc/core/silc-channels.c.
2690 * Reduced the default packet buffer size from 2048 to 1024 in
2691 lib/silccore/silcpacket.c.
2693 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2694 counter to the SKE context that is incresed when the SKE library
2695 performs async operation outside the library. If the outside
2696 process frees the SKE context and FREED status will be set
2697 and the library will detect after the sync operation that the
2698 libary is freed. The affected files are
2699 lib/silcske/silcske[_status].[ch].
2701 * Resolve the client entry information in the function
2702 silc_client_channel_message to assure that NULL pointer is not
2703 passed as client entry to the application. */
2705 * Fixed the task timeout calculation to assure that there is
2706 never negative timeouts. The affected file is
2707 lib/silcutil/silcschedule.c.
2709 * Fixed the channel user mode notification sending in server.
2710 It was sent point-to-point to the router (or to server by router)
2711 but it needs to be destined to a channel. The routines now
2712 supports sending the channel user mode notifys to the channels
2713 when announcing clients and channels. Affected files are
2714 silcd/server.c and silcd/packet_receive.c.
2716 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2717 It did not actually replace the old channel entry in the cache.
2718 Affected file lib/silcclient/client_notify.c.
2720 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * Fixed a possible crash in silc_packet_send_prepare. It now
2723 assures always that there is enough space in the buffer and
2724 at the tail area of the buffer (for MAC).
2726 Fixed the inbound buffer reallocation in silc_packet_read.
2727 It was old code and did not handle the reallocation correctly.
2730 The affected file is lib/silccore/silcpacket.c.
2732 * Fixed buffer overflow in silc_parse_nickname in the file
2733 lib/silcutil/silcutil.c.
2735 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * make install generates new server keys only if there is not
2740 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2742 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2743 Added check that if the NOREPLY is set then we will not send
2744 the away message. This avoids infinite loop of away messages
2745 if both clients are away. The affected file is
2746 lib/silcclient/client_prvmsg.c.
2748 * Fixed client crash if /NICK was given without arguments.
2749 Affected file lib/silcclient/command.c.
2751 * Server does not send the invite list in INVITE command back
2752 to the client if the list was not altered. Added this notion
2753 to the protocol spec as well. Affected file silcd/command.c.
2755 Fixed possible crash in INVITE command by checking the
2756 value of silc_server_get_client_route command.
2758 * Fixed the INVITE notify type handling. The arguments are now
2759 taken in correct order and client does not crash. The affected
2760 file is irssi/src/silc/core/silc-channels.c.
2762 Removed the "Inviting xxx to channel" message from the
2763 client library away and let the application handle it.
2764 Affected file lib/silcclient/command.c. Added that message
2765 to Irssi SILC client's message formats.
2767 * Fixed CMODE command crash in client. It now checks the
2768 amount of arguments correctly and does not crash. The affected
2769 file is lib/silcclient/command.c.
2771 * Do not create new channel automatically in silc_channels_join
2772 but check whether the channel by that name already exists.
2773 Affected file irssi/silc/core/silc-channels.c.
2775 * Do not send the SERVER_SIGNOFF to router if the disconnected
2776 entity was the router. Affected file silcd/server.c.
2778 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2779 SILC client as it was missing from there.
2781 Added the handling of the KICK notify to the Irssi SILC client
2782 as it was missing. Added "you have been kicked" message to
2783 Irssi SILC client's message modules formats.
2785 Added the handing of the KILL notify to the Irssi SILC client
2786 as it was missing. Added the kill message module formats
2789 The affected file is irssi/src/silc/core/silc-channels.c.
2791 * The router did not save the channel mode the server announced.
2792 Affected file silcd/packet_receive.c.
2794 * Fixed a possible crash in INFO command in server. If the
2795 server did not provide the server info it crashed. Affected
2796 file silcd/command.c.
2798 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Fixed the GETKEY command in the server to check also the
2801 global list. Otherwise the GETKEY would not work correctly
2802 in normal SILC server. Affected file silcd/command.c.
2804 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2806 * Fixed GETKEY crash, it crashed if the command did not succseed.
2808 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2810 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2811 is now real and not just an macro interface to GMP.
2813 Removed the entire GMP from the source tree and imported new
2814 NSS MPI library instead. Reason for removing GMP is that it is
2815 extremely large and compiles extremely slow. The NSS MPI
2816 is only a few files and compiles in less than 10 seconds.
2817 The speed is also about the same as GMP. The MPI is imported
2818 to lib/silcmath/mpi.
2820 If the system has GMP installed we will still use the GMP.
2821 If it is not then the NSS MPI will be compiled.
2823 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2825 * Merged a long nickname (127 characters long) crash bugfix from
2826 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2828 * Merged a freed memory reference bugfix from Irssi CVS tree.
2829 Affected file irssi/src/core/commands.c.
2831 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2833 * Added the server's public key sving and verification to the
2834 server when performing the SKE. This was missing and the
2835 remote server's (or router's) public key was accepted without
2836 checking whether we have it previously or trust it at all.
2837 Affected file silcd/protocol.c.
2839 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2841 * Check in the silc_server_timeout_remote if protocol is active
2842 and make sure that the protocol's final callback is called so
2843 that all memory if freed. Affected file silcd/server.c.
2845 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * silc_server_whois_send_reply crashed the server if the nickname
2848 was 127 characters long. Affected file silcd/command.c.
2850 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Added sanity check to the silc_server_new_client. If the hostname
2853 is provided inside username then check that the provided hostname
2854 really is the same as the resolved one. If the hostname was not
2855 resolved then check it from the public key. Affected file is
2856 silcd/packet_receive.c.
2858 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2859 if the server disconnected us and the connection is not valid
2860 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2862 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2863 the library to the lib/silcutil/silcutil.[ch].
2865 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Close log file after open. Affected file
2868 lib/silcutil/silclog.c.
2870 * Check whether sock == NULL in silc_client_send_packet and return
2871 if it is. Affected file lib/silcclient/silcclient.c.
2873 * Check rec->entry == NULL in the Irssi SILC Client before
2874 sending the channel message. Affecte file is
2875 irssi/src/silc/core/silc-servers.c.
2877 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * Merged a splitted window bugfix from Irssi CVS tree. The
2880 affected file is irssi/src/fe-text/textbuffer-view.c.
2882 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2883 It did not print nickname.
2885 * Improved the distributions system a bit.
2887 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2890 irssi/src/fe-text/gui-window.c.
2892 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2893 to in-active server. The affected file is
2894 irssi/src/silc/core/client_ops.c.
2896 * Resolve the client in USERS command reply if the entry does
2897 not have username resolved. The affected file is
2898 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2899 command to WHOIS command to really resolve stuff. The USERS
2900 is not used any more in any critical section so WHOIS can
2901 be used even though it might be slower than IDENTIFY.
2903 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2906 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Changed the protocol API a bit more consistent in the
2909 lib/silccore/silcprotocol.[ch].
2911 * Changed the following headers to ROBODoc format:
2913 lib/silccore/silcpayload.h
2914 lib/silccore/silcprotocol.h
2915 lib/silccore/silcsockconn.h
2917 All core library headers are now formatted.
2919 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Fixed a bug in Irssi SILC client; do not show that you are
2922 server/router operator if you really are not. Affected file is
2923 irssi/src/silc/core/client_ops.c.
2925 * Renamed silc_command_free_payload to silc_command_payload_free.
2926 Affected file lib/silccore/silccommand.h
2928 * Added silcmath.h to include the prototoypes of various routines
2929 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2932 * Changed the following headers to ROBODoc format:
2934 lib/silccore/silcchannel.h
2935 lib/silccore/silccommand.h
2936 lib/silccore/silcid.h
2937 lib/silccore/silcidcache.h
2938 lib/silccore/silcmode.h
2939 lib/silccore/silcnotify.h
2940 lib/silccore/silcpacket.h
2941 lib/silcmath/silcmath.h
2943 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Added checking to the server code not to start the server if
2946 ciphers and stuff are not configured properly. Affected files
2947 silcd/serverconfig.[h] and silcd/server.c.
2949 * Changed the layout of the header files of the public interfaces
2950 in the SILC libraries. The new layout supports ROBODoc
2951 documentation tool (and some others) so that it is easy to create
2952 a library reference manual. All the other headers and source
2953 code must still follow the CodingStyle document. Also source
2954 code must not include these ROBODoc stuffs, only the headers.
2955 Furthermore, all public interface headers must now be named
2956 by using `silc' prefix, example: silcapi.h, silccipher.h.
2957 Some files were renamed due to this. All the other headers
2958 must not be used as public interfaces. I will update the
2959 CodingStyle document later. Changed following headers, so far:
2961 lib/silcclient/silcapi.h
2962 lib/silccore/silcauth.h
2963 lib/silccore/silcprivate.h
2964 lib/silccrypt/silcdh.h
2966 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Removed silc_client_packet_send_flush from the client library
2971 as it is not needed. Affected file lib/silcclient/client.[ch].
2973 * Added printing of message of unresolved authentication method
2974 to the Irssi SILC client. Added it to the module formats.
2975 Removed the same message from the client library.
2977 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2979 * Added new distribution feature, DISTLABEL. Every distribution
2980 can define own preprocessor label that can be used in the
2981 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2982 file distributions, acconfig.h.pre and prepare.
2984 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2986 * Added Makefile.defines_int to include the actual definitions
2987 for Makefile.defines.in. Tested the new distribution system,
2988 created distributions and tested installation.
2990 * Added AWAY message printing to the Irssi SILC client. Added
2991 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2993 * Added SCONNECT command to call the SILC's CONNECT command.
2994 Cannot use CONNECT directly since Irssi uses that internally.
2995 Affected file irssi/src/silc/core/silc-servers.c.
2997 Added ACTION local command. It is same as ME command but takes
2998 the channel as mandatory argument.
3000 Rewrote some of the Irssi's help files to suite for SILC
3003 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Added Makefile.defines[.in] that should for now on be included
3006 in all Makefile.am file in the source tree. That file includes
3007 all common compilation definitions for SILC source tree.
3009 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Minor changes to the ./prepare script to change the package
3012 name according the distribution name to the configure.in.
3014 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3016 * Created new distribution system. Added file `distributions'
3017 that defines all the distributions that can be created out of
3018 the SILC source tree. The ./prepare script now reads that
3019 file to determine how to prepare the distributions. The
3020 first argument to the ./prepare is the name of the distribution
3021 and second is the version of the distribution. If given
3022 without arguments it creates the default (toolkit) distribution
3023 with the default version (defined in ./prepare).
3025 All Makefile.am files that are subject to the distributions
3026 are now named as Makefile.am.pre. These are ./Makefile.am
3027 and lib/Makefile.am. Others may be changed later.
3029 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Added invite list, ban list, some key management and connection
3032 error message printing to module formats in the Irssi SILC client.
3034 * Added new silc_client_set_away_message to set the away message
3035 that is back to the person who sent private message. The
3036 affected file lib/silcclient/silcapi.h and the
3037 lib/silcclient/client_prvmsg.c.
3039 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Fixed the private message sending in the Irssi SILC client,
3042 added local command KEY to the Irssi SILC client.
3044 Added key management and key agreement message formats to the
3045 irssi/src/fe-common/silc/module-formats.[ch].
3047 Added USERS (alias WHO) printing, server/router operator
3048 indication and LIST command printing to the module formats.
3050 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3052 * Fixed channel joining notify handling, cumode notify handling
3053 from Irssi SILC client.
3055 * Added SILC specific module-formats to the Irssi SILC client so
3056 that SILC specific message hilighting, colors etc is possible.
3057 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3059 Added channel mode, channel user mode, actions, notices,
3060 whois and whowas printing to the the module-formats.c.
3062 * Fixed a bug in channel deletion in the server. The channel
3063 is not left to the cache even if the channel founder auth mode
3064 is set when there are no users anymore on the channel. Affected
3065 file silcd/server.c.
3067 * The silc_net_localhost now resolves the entire hostname including
3068 the domain name. Affected file lib/silcutil/silcnet.c.
3070 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Changed the ask_passphrase client operation to be ascynchronous.
3073 It has now a completion callback and a context that the
3074 application must call after it has got the passphrase from
3075 the user. Affected files lib/silcclient/silcapi.h,
3076 lib/silcclient/protocol.c, lib/silcclient/command.c and
3079 Added SilcAskPassphrase callback that the application calls
3080 to deliver the passphrase to the library.
3082 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3083 The public key verification and especially a certificate
3084 verification is asynchronous procedure.
3086 Added new SILC_SKE_STATUS_PENDING status to indicate the
3087 request is pending and a callback will be called to finalize
3090 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3091 indicate that remote end did not send its public key (or
3092 certificate), even though we require it. Added check for this
3093 condition in the SKE. This was a security bug, now fixed.
3095 Defined new SilcSKEVerifyCbCompletion callback that is called
3096 when the verification process is completed.
3098 The affected files lib/silcske/silcske_status.h and
3099 lib/silcske/silcske.[ch].
3101 * Changed the verify_public_key client operation to be async
3102 as well. Defined SilcVerifyPublicKey callback that is used to
3103 indicate the success of the public key verification process.
3105 Changed the server and client to use the new async client
3108 * Changed the Irssi SILC client's internal scheduler to be called
3109 twice as many times as it used to be. As a result the client
3110 should be a bit faster now. Affected file is
3111 irssi/src/silc/core/silc-core.c.
3113 * Added support to Irssi SILC client of asynchronous public key
3114 verification and passphrase inquiry. Affected file is
3115 irssi/src/silc/core/silc-core.c.
3117 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Do not say "You have left channel %s" in client library.
3120 Moved it to the application. Affected files are
3121 lib/silcclient/command.c and silc/client_ops.c.
3123 * Fixed silc_client_get_clients. Command context was not
3124 duplicated and was freed memory in the callback. Affected
3125 file lib/silcclient/idlist.c.
3127 * Do not say "you are now talking..." on JOIN command in the
3128 client library. The appliation must handle it.
3130 * Do not say ".. changed topic to" in command reply in the
3131 client libary. The application must handle it.
3133 * Fixed TOPIC command sending in the client library.
3135 * Fixed a memory leak in silc_client_command_free in the file
3136 lib/silcclient/command.c.
3138 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Imported a modified version of Irssi client to the source tree.
3141 The Irssi will be used to create a new client called
3142 Irssi SILC. Imported to irssi/.
3144 Added silc_core_init_finish function to the Irssi. Affected
3145 file irssi/configure.in.
3147 A lot changes in the Makefile.ams around the irssi tree.
3149 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Do not rehash if the new size is same as the old size of the
3152 hash table, in the silc_hash_table_rehash*. The affected file
3153 lib/silcutil/silchashtable.c.
3155 * Replaced hash_table_del_by_context calls from the server
3156 (when channel->user_list and client->channels) to the
3157 hash_table_del as it is sufficient and faster.
3159 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Added silc_hash_table_list, silc_hash_table_get and the
3162 SilcHashTableList structure to provide an alternative way to
3163 traverse the hash table. The affected files are
3164 lib/silcutil/silchashtable.[ch].
3166 * Changed the server's idlist routines to use the hash table
3167 routines to optimize the code.
3169 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Replaced the client entry's `channel' list and channel entry's
3172 `user_list' list to hash tables for optimized lookup. Changed
3173 the code to use the hash table interface around the code.
3174 Affected file lib/silcd/idlist.[ch].
3176 * Added `auto_rehash' boolean argument to the function
3177 silc_hash_table_alloc to indicate whether the hash table should
3178 auto-rehash when it thinks is appropriate time. It will
3179 increase the hash table size if the there is twice as much
3180 entries in the table than the size of the table, and will
3181 decrease the size if there are twice as less entries than
3182 the size of the table.
3184 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3188 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * silc_idcache_purge_by_context deletes the entry now by context
3191 as it is supposed to do. Affected file lib/silccore/idcache.c.
3193 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3194 client is not anymore valid (WHOWAS givens the info) and not
3195 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3197 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * Removed the `data' and `data_len' arguments from the ID Cache
3200 interfaces and added `name' argument. ID Cache does not handle
3201 anymore the binary data only a names associated with given ID.
3203 * When hashing a Client ID with silc_hash_id the entire ID is
3204 not hashed anymore, instead only the hash of the Client ID is
3205 hashed. This way we can access the Client ID from the cache
3206 with Client ID but with the hash of the ID (which is a hash of
3207 the nickname) as well without any difference in performance.
3209 Added also silc_idcache_find_by_id_one_ext to do one on one
3210 searching when we have the actual ID. Added also function
3211 silc_hash_client_id_compare. The affected files are
3212 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3214 * When hashing the name associated with a ID it is always done
3215 in lowercase. This way we can access the cache without worrying
3216 about case-sensitivity, even though, for example nicknames are
3219 * Fixed a bug in server with channel message sending. It put
3220 wrong ID type as destination ID. The affected file
3221 silcd/packet_send.c.
3223 * silc_idcache_del_by_context now deletes from all hash tables
3224 by context. Affected file lib/silccore/idcache.c.
3226 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Changed the client library to use the new ID Cache interface.
3229 Changes around the source tree.
3231 * Added silc_hash_table_rehash_ext to rehash with specific
3232 hash function. Affected file lib/silcutil/silchashtable.[ch].
3234 * Added silc_hash_string_compare to compare two strings in the
3235 hash table. Affected file lib/silcutil/silcutil.[ch].
3237 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Added new function silc_idcache_del_by_context into the
3240 lib/silccore/idcache.[ch].
3242 * Changed the server's ID list routines to use the new ID Cache
3243 interface. Changes around the source tree.
3245 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Added silc_hash_table_del[_by_context]_ext functions in to the
3248 lib/silcutil/silchashtable.[ch].
3250 Removed silc_hash_table_find_all* routines and added new
3251 silc_hash_table_find_foreach to replace them.
3253 Added silc_hash_table_replace_ext function as extended
3254 replacing function. Separated the simple hash table interface
3255 from the extended hash table interface in the file
3256 lib/silcutil/silchashtable.h.
3258 * Fixed minor bugs and changed it to use some of the new
3259 hash table functions in lib/silccore/idcache.c
3261 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * Added new function silc_hash_table_find_all to return all keys
3264 in the hash table by the specified key. As the hash table is
3265 collision resistant it also makes it possible to have several
3266 duplicate keys in the hash table. This function may be used to
3267 find all of the keys from the hash.
3269 Added user_context arguments to the SilcHashFunction,
3270 SilcHashCompare and SilcHashDestructor to deliver user specified
3273 Added new fuctions silc_hash_table_find[_all]_ext to do
3274 extended lookup with specified hash and compare functions and
3275 specified user contexts.
3277 Added new function silc_hash_table_add_ext to add the key
3278 with specified hash function and user context.
3280 Added new function silc_hash_table_foreach to traverse all
3281 entrys in the hash table. Added SilcHashForeach callback
3284 Added new function silc_hash_table_del_by_context to delete
3285 the entry only if the context associated with the key matches.
3287 Affected files are lib/silcutil/silchashtable.[ch].
3289 * Removed silc_hash_[server/client/channel]_id and added just
3290 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3291 silc_hash_id_compare to compare two ID's using as the hash table
3292 comparison function. Added also silc_hash_data to hash
3293 binary data and silc_hash_data_compare to compare it.
3295 * Removed silc_idlist_find_client_by_hash as it is not needed
3296 anymore. Affected file silcd/idlist.[ch].
3298 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3299 to use internally the SilcHashTable. The new ID Cache is a lot
3300 faster than the old one. Some of the ID Cache interface was also
3301 rewritten and obsolete and stupid functions were removed.
3303 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3305 * Added entry_count field to the SilcHashTable to keep the number
3306 of the entries in the table. Implemented the function
3307 silc_hash_table_rehash. Added new function
3308 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3310 Fixed a minor bug in silc_hash_table_free.
3312 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3313 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3314 into the lib/silcutil/silcutil.[ch].
3316 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Implemented a collision resistant hash table into the
3319 lib/silcutil/silchashtable[ch]. See the header and the source
3320 for the SilcHashTable API.
3322 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3324 * Merged dotconf version 1.0.2 into lib/dotconf.
3326 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3328 * Do not compile anything in lib/silcsim/* if the SIM support
3329 is not enabled. The tree should now compile without problems
3332 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Compiled the SILC under cygwin. Compiled and tested briefly
3335 without problems. More tests needed. The SIMs didn't compile
3338 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3340 * Fixed possible crash in silc_get_username in the
3341 lib/silcutil/silcutil.c.
3343 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Fixed a va_arg in silc/client_ops.c.
3347 * Oops, RC5 routines were named AES and caused some problems
3348 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3350 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * Added new SilcIDIP structure into the lib/silccore/id.h and
3353 replaced the old `ip' fields from all SILC ID's to that type.
3354 This is a step towards IPv6 support.
3356 The silc_id_get_len takes now the ID as an extra argument.
3357 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3358 both IPv4 and IPv6 based ID's.
3360 The affected files are lib/silccore/id.[ch] and other files
3361 around the tree using these routines.
3363 * Removed the ID length arguments in server from various
3364 silc_server_send_notify_* routines -> they are not needed
3367 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Fixed memory leak in silc_encode_pem_file in the file
3370 lib/silcutil/silcutil.c.
3372 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * Check minor version as well in the SKE. Affected files are
3375 silcd/protocol.c and lib/silcclient/protocol.c.
3377 * Added --identifier option to the server so that an identifier
3378 can be when creating the public key for the server. Affected
3379 file is silcd/silcd.c.
3381 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3382 lib/silccrypt/silcpkcs.c.
3384 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3386 * Register default ciphers and stuff when using -C option with
3387 the server. Affected file sildc/silcd.c.
3389 * Put back the servers public key filename format, it is better
3390 than the new one. For now, the client keys are saved with the
3391 new filename format. The affected file silc/client_ops.c.
3393 * Implemented the Cipher API for the rest of the ciphers that
3394 did not implement it or implemented it the wrong way.
3396 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Register default ciphers and stuff when using the -S option
3399 in the client. Affected file silc/silc.c. Same also when
3400 creating new key pair with -C option.
3402 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3404 * Fixed the silc_verify_public_key client operation function to
3405 save the public keys differently. The fingerprint is now
3406 used as filename and not the hostname. This way also the
3407 client keys are saved uniquely and not with hostnames. The
3408 affected file is silc/client_ops.c.
3410 * Trimmed the silc_hash_fingerprint function to remove extra
3411 whitespaces from the end of the fingerprint. The affected
3412 file is lib/silccrypt/silchash.c.
3416 * Added silc_cipher_register_default function to register all
3417 default ciphers. It can be used when configuration files
3418 does not exist and the application does not want any specific
3419 ciphers in any specific order.
3421 The SilcDList is now used as silc_cipher_list dynamically
3422 allocated cipher list. Removed the static list all together
3423 and now all ciphers must be allocated to the dynamic list.
3424 The silc_cipher_alloc routine was changed to check only the
3427 All silc_cipher_* routines that used to return int returns
3430 The affected files lib/silccrypt/silccrypt.[ch].
3432 * The same thing was done to silc_hash_* as for silc_cipher_*
3433 routines. Affected files lib/silccrypt/silchash.[ch].
3435 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3436 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3437 Added also silc_pkcs_[un]register[_default] functions.
3438 Removed the data_context from the PKCS API.
3440 * Added silc_hmac_register_default function to register default
3441 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3442 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3443 to unregister all hmacs at once.
3445 * Register the default ciphers, hash functions, PKCSs and HMACs
3446 if client's configuration file does not exist. The affected
3449 * The client did not load the hash functions from the SIM
3450 modules at all. Added support for this. Affected file is
3451 silc/clientconfig.c.
3453 * When decoding public key with silc_pkcs_public_key_decode, check
3454 the supported algorithm only if PKCS are registered. Affected
3455 file lib/silccrypt/silcpkcs.c. The same was done with the
3456 silc_pkcs_private_key_decode.
3458 * Fixed the SILC List routines to keep the list always in order.
3459 It used to change the list's order when traversing the list but
3460 not it preserves the order. Affected file lib/trq/silclist.h.
3462 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Added the client library to use the SilcSocketConnection's
3465 reference counter (by silc_socket_dup) to prevent the bug that
3466 the socket object may be freed underneath async operation.
3468 * The name resolv library checking fixes in the configure.in.pre.
3471 * Created new version of the protocol drafts for future
3472 development. The -03 drafts are the ones that will be changed
3473 in the trunk now and the -02 will remain as they are.
3475 * Send list of CUMODE notifys to the router when announcing
3476 the channel users to the router. Affected file silcd/server.c.
3477 If the router receiving channel founder CUMODE for a channel
3478 that already has channel founder it will send CUMODE notify
3479 to the sender to remove the channel founder rights from the
3480 announced client. Affected file silcd/packet_receive.c.
3482 * The CUMODE notify may now use Server ID as well as the entity
3483 who changes the mode. Updated protocool specs.
3485 * Updated INSTALL and README files.
3487 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * New web pages in the http://silc.pspt.fi. The pages was
3494 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * Implemented the [DenyConnectin] config section in the server.
3497 Added silc_server_config_denied_conn to check whether incoming
3498 connection is denied. Affected file silcd/serverconfig.[ch].
3500 * Do not check the ports when checking the incoming configuration
3501 data if the port is 0, meaning any. Affected file is
3502 silcd/serverconfig.c.
3504 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3506 * Fixed buffer overflow in silc_string_compare in the file
3507 lib/silcutil/silcutil.c.
3509 * Fixed double free in silc_server_command_leave in the file
3512 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Fixed the version checking in the server. Affected file is
3517 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Fixed the configuration data fetching when accepting new
3520 connections in the server. Affected file silcd/server.c.
3522 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Added `sender_entry' argument to the function
3525 silc_server_packet_relay_to_channel so that we can check
3526 whether some destination actually belongs to the same route
3527 the sender belongs (ie, we must not resend the packet to the
3528 sender). Affected file silcd/packet_send.[ch].
3530 * Added `servername' field to the SilcClientEntry in the server
3531 to hold the name of the server where client is from. Affected
3532 file is silcd/idlist.h.
3534 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Moved the channel message encrypting in the router betwen
3537 router connections from silc_server_channel_message to the
3538 silc_server_packet_relay_to_channel since we want to check
3539 whether we have anybody channel before encrypting anything.
3540 Affected files silcd/packet_[receive/send].c.
3542 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * Fixed the [AdminConnection] server config section to support
3545 multiple entries. Affected file silcd/serverconfig.c.
3547 * Added support into the server to check the validity of the
3548 incoming connection before executing any KE or authentication
3551 * The connection configuration is now saved to the KE and
3552 connection auth protocol contexts and not fetched anymore in
3553 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3555 * The local hosts listenning address and port is also resolved
3556 now when starting the server. We want to have the socket object
3557 to include the real address and port for the listener. Added
3558 new function silc_net_check_local_by_sock into the files
3559 lib/silcutil/silcnet.[ch].
3561 * Fixed a broadcast bug in server -> do not broadcast if we
3564 * Fixed a routing bug. Do not route broadcast packets ever.
3565 Broadcast packets must be processed always and not routed since
3566 they may be destined to some other host than yourself and thus
3567 would get routed without no good reason. Affected file is
3570 * Added function silc_server_config_is_primary_route to check
3571 whether primary router connection has been configured (a router
3572 configuration that we are initiating). If there is not, we
3573 will assume that there is only two routers in the SILC network
3574 and we will use the incoming router connection as our primary
3575 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3577 * Changed the order of the broadcasting. Broadcast _after_ the
3578 packet has been processed not before. Affected file is
3581 * Fixed a [ClientConnection] parsing bug. The port was never
3582 parsed correctly thus resulting to port 0. Affected file
3583 silcd/serverconfig.c.
3585 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3586 argument and did not set the broadcast packet flag. Affected
3587 file silcd/packet_send.c. Fixed same bug in the function
3588 silc_server_send_notify as well.
3590 * If we receive NEW_ID packet for our own ID in the server, ignore
3593 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Removed the nickname from the Private Message Payload.
3598 Updated the code and the protocol specs.
3600 * Updated protocol specs for submitting to the IETF.
3602 * Tweaked the Random Number Generator a bit. Affected file
3603 lib/silccrypt/silcrng.c. Exported a new function
3604 silc_rng_[global]_add_noise which can be used to add more
3607 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3609 * Do not parse packets with different timeout when protocol
3610 is active -> may cause problem with rekey. Affected file
3613 * When server receives signoff notify it must not create
3614 new channel key if the client is on any channels since the
3615 sender of the signoff notify will create it.
3617 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3619 * Added printing of error messages during SKE protocol from the
3620 failure packet sent by server during SKE. Affected file
3623 * Removed the client's failure_callback handling with timeout
3624 and handle it immediately when received.
3626 * The SKE library returned wrong type in SUCCESS and FAILURE
3627 packets. They must be 32 bit MSB not 16 bit MSB.
3629 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3631 * Ok, rewrote the logic of the re-key and now it seems to work.
3632 I tested it on high traffic with frequent re-keys without
3633 problems. Added hmac_receive (and renamed hmac to hmac_send)
3634 in SilcClientConnection in lib/silcclient/client.h and
3635 in SilcIDListData in silcd/idlist.h. Also, removed the
3636 SilcPacketParserContext's cipher and hmac fields as they are
3637 not needed anymore and actually caused some problems when
3638 the ciphers and hmac's changed underneath the packet parser.
3640 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * If re-key protocol is active then process the incoming packets
3643 synchronously since we must assure that icoming packets encrypted
3644 with the old key is processed before the new keys is set to
3645 use. This is true other packets than for REKEY packets.
3646 Affected file silcd/server.c. The same was done to client library
3647 as well, affected file lib/silcclient/client.c.
3649 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3651 * Fixed bug in client and server to accept the force send if
3652 the packet is send from silc_[server/client]_packet_process
3653 function. Otherwise the packets are never delivered, oops.
3655 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Disable force sending of packets when REKEY protocol is active.
3658 We must assure that no packet is sent directly when rekey is
3659 performed. All packets must be sent through packet queue.
3660 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3661 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3662 function is silc_[server/client]_packet_send_real to check
3665 * Replaced the SIM paths from example config files to
3666 /usr/local/modules. Also, make install creates now
3667 /usr/local/silc/logs directory to hold all the SILC server
3670 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Made the configure.in.pre work on Solaris. Patch by salo.
3674 * Made all ciphers compatible with non-x86 machines. Defined
3675 CBC mode macros into lib/silccrypt/ciphers_def.h.
3677 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3679 * Fixed the make install.
3681 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * When MAC computation fails the silc_packet_decrypt returned 0
3684 even though it was supposed to return -1. Fixed this. The
3685 affected file is lib/silccore/silcpacket.c.
3687 * Do not replace the config files in /etc/silc (in make install)
3688 if they already exist. Affected file ./Makefile.am.
3690 * Do not send re-key packets immediately but through packet queue.
3691 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3693 * Changed silc_net_check_host_by_sock to return FALSE if the
3694 IP/DNS could not be resolved. Though, it returns the IP address
3695 now even if it could not resolve it (but returns also FALSE).
3696 Affected file lib/silcutil/silcnet.[ch].
3698 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Added silc_pkcs_decode_identifier to decode the public key's
3701 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3702 Added also silc_pkcs_free_identifier. Added also new context
3703 SilcPublicKeyIdentifier.
3705 * Added -S option to the silc client. It is used to dump the
3706 contents of the specified public key file.
3708 * Changed the PKCS api to return the public key length when
3709 setting the public key.
3711 * Fixed a fatal bug in the public and private key file loading.
3712 Affected file lib/silccrypt/silcpkcs.c.
3714 * Execute the packet parsing for client with zero (0) timeout
3715 if the protocol is active. Affected file silcd/server.c.
3717 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Made the key generation options to the silcd program. Added
3720 -C option, equivalent to client's option.
3722 * Added new [ServerKeys] config section to the server. It
3723 configures the server's public and private key.
3725 * Defined generic Public Key Payload into the protocol
3726 specification to send specific type of public keys and
3729 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3730 public key or certificate.
3732 * Implemented the GETKEY command to the server and to the
3733 client library and on user interface.
3735 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3737 * Made preliminary `make install' work.

3741 * Added SilcServerRekey context into silcd/idlist.h.
3743 * Added the PFS support as defined in the specification to the
3744 SKE protocol. Affected files lib/silcske/*.c.
3746 * Added `ske_group' field to the SilcServerRekey context to hold
3747 the number of the SKE group that is used with PFS in re-key.
3748 Affected file silcd/idlist.h.
3750 * Added PFS re-key support to the server. Affected file is
3753 * Added silc_protocol_cancel to cancel execution of the next
3754 state of the protocol. Affected file is
3755 lib/silccore/silcprotocol.[ch].
3757 * Added the re-key support with and without PFS to the client
3758 library. Re-key is performed once in an hour, by default.
3760 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3761 Added silc_client_rekey_callback and silc_client_rekey_final.
3762 Affected files are lib/silcclient/protocol.[ch] and
3763 lib/silcclient/client.[ch].
3765 * Removed the `hmac_key' and `hmac_key_len' fields from the
3766 SilcClientConnection structure; not needed. Affected file is
3767 lib/silcclient/client.h.
3771 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * Do not ask whether user wants to use the negotiated private key
3774 for private messages, just use it. Affected file is
3775 silc/local_command.c.
3777 * Added `send_enc_key' and `enc_key_len' fields to the
3778 SilcIDListData structure since they are needed in the re-key
3779 phase. Affected file is silcd/idlist.[ch].
3781 * Implemented the simple re-key protocol into the server.
3782 Affected files silcd/server.c and silcd/protocol.[ch]. The
3783 re-key will be performed once in an hour, by default.
3785 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3786 Added silc_server_rekey, silc_server_rekey_callback and
3787 silc_server_rekey_final.
3789 * Removed Tunneled flag from the protocol. Updated the code
3790 and the specifications.
3792 * Adde `pfs' field to the SilcIDListData to indicate whether
3793 the PFS is to be performed in the re-key. Affected file is
3796 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3799 int64 of at least the xintXX size. If void * is less that 4
3800 bytes uint32 * will be used. Defined bool as boolean.
3802 * Changed _ALL_ unsigned long and unsigned int to uint32,
3803 unsgined short to uint16 in the source tree.
3805 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3806 not handle clients that has entry->data.registered == FALSE.
3807 They are not in the network anymore. Affected file is
3810 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Implemented the sending of the SERVER_SIGNOFF notify in the
3813 server. Affected file is silcd/server.c.
3815 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3816 Added also silc_notify_payload_encode_args into the
3817 lib/silccore/silcnotify.[ch].
3819 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3820 Affected file silcd/packet_receive.c.
3822 * Implemented the SERVER_SIGNOFF notify handling in the client
3823 library. Affected file lib/silcclient/client_notify.c. Also,
3824 implemnted the printing of the SERVER_SIGNOFF info to the
3825 application. Affected file silc/client_ops.c.
3827 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3828 if the deleting was successful. Affected file silcd/idlist.[ch].
3830 * Added support for public key authentication in the connection
3831 authentication protocol in the client library. Affected file
3832 lib/silcclient/protocol.c.
3834 * Changed the server's silc_idlist_get_clients_by_* interface
3835 to support already allocated array so that new entries may be
3836 added to pre-allocated array. Affected file silcd/idlist.[ch].
3837 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3838 and command replies.
3840 * All command reply functions in the server now calls the
3841 pending command callback even if error occured. This way the
3842 error will be delivered to the client as well. Affected files
3843 silcd/command.c and silcd/command_reply.c.
3845 * Fixed INFO command to return local server's info if no server
3846 was provided. Affected file lib/silcclient/command.c.
3848 * Removed RESTART command for good. Updated the code and the
3851 * Rewrote parts of the task system. It is a bit simpler now.
3852 Removed unsued task priorities. The affected files are
3853 lib/silcutil/silctask.[ch].
3855 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Moved the USERS printing from the library to the application.
3858 Affected files lib/silcclient/command.c and silc/client_ops.c.
3860 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Added channel key re-key support. The re-key is perfomed
3865 only by the router and is done once in an hour. Added `rekey'
3866 field to the SilcChannelEntry in the server. Affected files
3867 silcd/server.c and silcd/idlist.h.
3869 * Added silc_task_unregister_by_context into the file
3870 lib/silcutil/silctask.[ch].
3872 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Added SILC_UMODE_GONE mode to indicate when the client is not
3875 present in the SILC network. Added also support to the local
3876 command AWAY that will set this mode. Added support of showing
3877 "xxx is gone" in WHOIS command. The USERS command shows the
3878 gone status as well.
3880 * Fixed setting server and router operator privileges in the
3881 server's UMODE command. Affected file silcd/command.c.
3883 * Merged the SKE KE1 and KE2 payloads into one payload. The
3884 new KE payload is equivalent to the old KE2 payload.
3886 Cleaned up the SKE Start Payload parsing. It now uses the
3887 simple buffer unformatting to do the parsing. A lot faster
3890 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3891 to the SKE that is used to indicate whether both of the SKE
3892 parties should perform authentication. By default only the
3893 responder performs authentication. By setting this flag also
3894 the initiator must do authentication. By default it is unset
3895 since in normal SKE case, client to server connection, only
3896 the responder should do authentication. When doing SKE between
3897 two clients both should perform authentication. Updated the
3898 code and the protocol specs.
3900 * A little fix to IDENTIFY command in the server. Search the
3901 client first by hash not nickname. Affected file is
3904 * Fixed the silc_client_close_connection to support closing
3905 the client to client connections wihtout deleting too much
3906 data. Affected file lib/silcclient/client.c.
3908 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3909 are received if protocol used to be active but is not anymore
3910 the application would crash due to NULL pointer dereference.
3911 Affected files silcd/server.c and lib/silcclient/client.c.
3913 * Added `hash' field to the SilcClientConnection to include
3914 the hash function negotiated in the SKE protocol.
3916 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3917 to set the channel founder authentication data. A client can
3918 claim the founder rights later by providing the authentication
3919 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3920 This way the channel founder can regain the channel founder
3921 privileges even it is left the channel. This works only on
3922 local server and the client must be connected to the same
3923 server to be able to regain the founder rights. Updated the
3924 protocol specs accordingly.
3926 Added support to the CMODE command in the client to set the
3927 founder auth data. Read the README to see how to set it.
3929 Added support to the CUMODE command to claim the founder
3930 rights. Read the README to see how to do it.
3932 Added support for the founder authentication to the Channel
3933 Entry in the server. Affected file silcd/idlist.h.
3935 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3936 server's CMODE command. Affected file silcd/command.c.
3938 * Added the following new functions into lib/silccore/silcauth.[ch]:
3939 silc_auth_get_method and silc_auth_get_data.
3941 * The server now saves the remote hosts public key to the
3942 SilcIDListData pointer. Affected file silcd/protocol.c.
3944 * The normal server now does not remove the channel entry from
3945 the cache if the founder authentication data is set. It used
3946 to remove it if the founder was the last one on the channel on
3947 the server and left the channel. The auth data is saved and
3948 if the channel is re-joined later the old entry is used with
3949 the old auth data. Affected files silcd/command_reply.c and
3952 * Removed the `pkcs' field from the SilcIDListData structure
3953 in the server; it is not used. Affected file silcd/idlist.h.
3955 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Fixed packet processing on slow links. Partial packets were
3958 never re-processed because the incoming data buffer was cleared
3959 by the application. Application must not directly clear the
3960 sock->inbuf, the packet processing routines handle it. Fixed
3961 this in client library and in server.
3963 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Fixed the WHOIS and IDENTIFY send reply function to really
3966 check whether to send list or just one entry. Affected file
3969 * Cleaned up the LEAVE command's channel key distribution. The
3970 affected file silcd/command.c.
3972 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3973 can enforce the channel mode as well. In that case the ID
3974 includes the ID of the server. The code now enforces the
3975 mode change if the router have different mode than the server.
3977 * The notify client operation with CMODE_CHANGE notify can now
3978 return NULL client_entry pointer if the CMODE was not changed
3979 by client. Application must check for this.
3981 * Added <Server ID> argument to INFO command to support server
3982 info fetching by Server ID.
3984 * Added silc_server_announce_get_channel_users to get assembled
3985 packets of channel users of the specified channel. Affected
3986 file silcd/server.[ch].
3988 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3989 was freed underneath the ID Cache.
3991 * Re-announce clients when the server received CHANNEL_CHANGE
3992 notify from the router. Affected file silcd/packet_send.c.
3994 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3997 crashed since it did not handle the fact that there is no cipher
3998 called "3" and didn't check the error condition. Now fixed.
4000 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4001 flag. It can be used to send message requests.
4003 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Implemented the RESTART command in the client.
4007 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4008 notice type messages. Added notice printing to the user
4011 * The channel keys are not re-generated if the channel's mode
4012 is PRIVKEY, ie private key on the channel exists. Affected
4013 files silcd/server.c and silcd/command.c.
4015 * Fixed a little bug in channel message delivery when channel
4016 private keys are set in the server. Affected file is
4017 silcd/packet_send.c.
4019 * Changed the setting on channel->on_channel = TRUE from the
4020 silc_client_save_channel_key to the JOIN command reply. The
4021 key payload is not received if the private channel key is set.
4022 Affected file lib/silcclient/command_reply.c and the
4023 lib/silcclient/client_channel.c.
4025 * When the CMODE_CHANGE notify is sent and the channel private
4026 key mode is removed the channel key must be re-generated in
4027 other cells as well. Added this support for the router in the
4028 silcd/packet_receive.c.
4030 * Added new local command NOTICE to send notice message on
4031 channel. Affected file silc/local_command.[ch].
4033 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Added new local command ME to the client. It is used to send
4036 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4037 some action. Affected file silc/local_command.[ch].
4039 * Changed channel_message and private_message client operations
4040 to deliver the message flags to the application. Added also
4041 the `flags' arguments to the silc_client_send_channel_message
4042 and silc_client_send_private_message functions. Affected file
4045 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Redefined the Private Message Payload to support private message
4048 keys and to support the new private message flags. Updated
4049 the protocol specs. Flags makes it possible to have for example
4050 CTCP style messages.
4052 * Added new type SilcPrivateMessagePayload and defined an API
4053 for it in the lib/silcclient/silcprivate.[ch].
4055 * Tested private message private keys successfully. Tested the
4056 private message key set, unset and list commands with the new
4059 * Redefined the Channel Message Payload to include the channel
4060 message flags (equal with private message flags) to support
4061 for example CTCP style messages.
4063 * Defined some of the message (for channel and private message)
4064 flags. Updated the protocol specs and added the flags to the
4065 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4067 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Added SilcKeyAgreementStatus type to the key agreement routines
4070 to indicate the current status and error if one occured.
4071 The status types are defined in the lib/silcclient/silcapi.h.
4073 * Added new local command KEY that is used to set and unset private
4074 keys for channels, set and unset private keys for private messages
4075 with remote clients and to send key agreement requests and
4076 negotiate the key agreement protocol with remote client. The
4077 key agreement is supported only to negotiate private message keys,
4078 it currently cannot be used to negotiate private keys for channels,
4079 as it is not convenient for that purpose.
4081 * Fixed a minor pending callback setting bug in the function
4082 silc_client_get_client_by_id_resolve, now the function works.
4083 Affected file lib/silcclient/idlist.c.
4085 * Added function silc_net_get_local_port to get local bound
4086 port by socket. Added to lib/silcutil/silcnet.[ch].
4088 * Added `sockets' and `sockets_count' fields to the SilcClient
4089 object. They hold the sockets of the listenning sockets in
4090 the client. Listenning sockets may be for example the key
4091 agreement server. Affected file lib/silcclient/client.[ch].
4092 Added functions the silc_client_add_socket and the
4093 silc_client_del_socket. They are exported to the application
4096 * Added ~./silc/clientkeys to support other client's public keys.
4098 * Renamed verify_server_key client operation to verify_public_key
4099 and added one argument to indicate the type of the connection
4100 (server, client etc.).
4102 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Added silc_server_connection_auth_request to handle the
4105 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4106 silcd/packet_receive.[ch].
4108 * Added silc_server_send_connection_auth_request into the
4109 silcd/packet_send.c to send the connection auth request packet.
4111 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4114 * Fixed the public key authentication in responder side in the
4115 server. The `auth_data' pointer includes the SilcPublicKey
4116 not the path to the public key. Affected file silcd/protocol.c.
4118 * Implemented the public key authentication in the initiator side
4119 in the server. Affected file silcd/protocol.c.
4121 * Removed the [RedirectClient] config section from the server
4122 configuration. Is not needed and I don't want to implement it.
4124 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4126 * Cleaned up the CMODE command in the server. It now works
4127 correctly and supports all the modes defined in the protocol.
4128 Affected file is silcd/command.c.
4130 * Added `hmac_name' field to the SilcChannelEntry in the server
4131 to hold the default HMAC of the channel. It can be set when
4132 creating the channel (with JOIN command). Affected files
4135 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4136 type to indicate the change of the current cipher and hmac
4137 on the channel. Client can safely ignore the <cipher> argument
4138 (if it chooses to do so) since the CHANNEL_KEY packet will
4139 force the channel key change anyway. The <hmac> argument is
4140 important since the client is responsible of setting the new
4141 HMAC and the hmac key into use.
4143 * Fixed the CMODE command in the client library as well.
4145 * Tested CMODE command in router environment successfully.
4147 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Show the version of the remote client (or server) when connecting
4150 to the server. It is logged to the log file. Affected file
4151 is silcd/protocol.c.
4153 * Fixed the KILLED notify handling in the client library. The
4154 client must be removed from all channels when receiving the
4157 Also, do not remove the client entry when giving the KILL
4158 command but when the KILLED notify is received.
4160 * Removed silc_idlist_find_client_by_nickname from the server.
4161 Not needed anymore. Affected files silcd/idlist.[ch].
4163 * Implemented the CHANNEL_CHANGE notify type handling to the
4164 server. Affected file silcd/server.c.
4168 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Added silc_server_send_notify_invite to send the INVITE
4171 notify between routers.
4173 * Implemented the INVITE command correctly to the server.
4175 * Implemented the INVITE notify type handling in the server.
4177 * Implemented the INVITE command to the client library and on the
4180 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4182 * Added function silc_server_get_client_resolve to find the
4183 client entry by ID from all ID lists and then resolve it
4184 (using WHOIS) if it cannot be found. Affected file is
4187 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Implemented the BAN command to the client library.
4191 * The JOIN command in the server now checks the invite list
4194 * Changed the silc_command_reply_payload_encode_va and the
4195 silc_command_payload_encode_va to support that if argument is
4196 NULL it ignores and checks the next argument. Affected file
4197 lib/silccore/silccommand.c.
4199 * Added silc_server_send_notify_ban to send the BAN notify
4200 type between routers.
4202 * Chaned the silc_notify_payload_encode to support that if
4203 argument is NULL it ignores and checks the next argument.
4204 Affected file lib/silccore/silcnotify.c.
4206 * Tested ban lists in router environment successfully.
4208 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Implemented BAN command to the server, in silcd/command.[ch].
4212 * Removed the BAN and INVITE_LIST modes from the CMODE command
4215 * Added function silc_string_match to regex match two strings.
4216 Affected files lib/silcutil/silcutil.[ch].
4218 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Redefined parts of the SilcChannelEntry in the server to support
4221 the new ban and invite lists.
4223 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Redefined the INVITE command. The same command can be used to
4226 invite individuals to the channel but also to manage the invite
4227 list of the channel (to add to and remove from the invite list).
4228 Updated the protocol specs.
4230 * Added new command SILC_COMMAND_BAN that can be used to manage
4231 the ban list of the channel. Updated the protocol specs.
4233 * Removed the channel modes: the SILC_CMODE_BAN and the
4234 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4235 in the CMODE command. The equivalent features are now available
4236 using INVITE and BAN commands. Updated the protocol specs.
4238 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4239 in the network about change in the current ban list. The notify
4240 type is not used by the client.
4242 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4243 support the invite lists.
4245 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Added new function silc_string_regexify that converts string
4248 including wildcard characters into regex string that can
4249 be used by the GNU regex library. Added into the file
4250 lib/silcutil/silcutil.[ch].
4252 Added silc_string_regex_combine to combine to regex strings
4253 into one so that they can be used as one regex string by
4254 the GNU regex library. Added into the file
4255 lib/silcutil/silcutil.[ch].
4257 Added silc_string_regex_match to match two strings. It returns
4258 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4260 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Imported GNU regex to the soruce tree into lib/contrib.
4263 Fixed some compiler warning from the regex.c.
4265 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Fixed MOTD command in the server to work in router environment.
4269 * Fixed the MOTD command in the client library to support
4270 the server argument in the command.
4272 * Added `nickname_len' argument to the silc_idlist_add_client
4273 in the server, as the `nickname' argument may be binary data
4276 * Added silc_idlist_get_channels to return all channels from
4279 * Implemented LIST command to the server. Affected file is
4282 * Implemented the LIST command to the client library and on the
4285 * Added [<user count>] argument to the LIST command reply.
4286 With private channels the user count is not shown.
4288 * Updated TODO and README.
4290 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * The client entry's data.registered must be TRUE even with
4293 global client entry on global client list. The data.registered
4294 is used to check whether the client is anymore in the network,
4295 for example with WHOWAS command so it must be valid.
4297 * Fixed the WHOWAS command in the server. It now actually works
4298 in router environment. Added function into silcd/command_reply.c
4299 silc_server_command_reply_whowas_save.
4301 * Added silc_idlist_purge function to the silcd/idlist.c
4302 to periodically purge the ID Cache.
4304 * Fixed INFO command in the server. It works now in router
4305 environment. Added <server name> argument to the INFO command
4306 reply. Updated the protocol specs.
4308 * Fixed minor bug in silc_idcache_purge to not purge if the
4309 expire value is zero.
4311 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4312 they were buggy because of the WHOWAS information.
4314 * Fixed local command MSG to handle the async resolving of
4315 the remote client properly. It used to fail the first MSG.
4316 Affected file silc/local_command.c.
4318 * Added `data_len' field to SilcIDCache context.
4320 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Update TODO. Todo in commands in the server.
4324 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4327 used by routers as broadcast packet to inform other routers
4328 about the changed user mode.
4330 Implemented the notify handling in the server. Affected file is
4331 silcd/packet_receive.c. Added the function
4332 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4334 * Added new generic Channel Payload and deprecated the New Channel
4335 Payload. The New Channel Payload is now the generic Channel
4338 * Added new argument `mode' to the silc_server_send_new_channel
4339 as it is required in the Channel Payload now.
4341 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4342 and created a new and real SilChannelPayload to represent the
4343 new generic Channel Payload. Implemented the encode/decode
4344 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4346 * Added silc_server_get_client_channel_list to return the list
4347 of channels the client has joined for WHOIS command reply.
4348 Affected file silcd/server.[ch].
4350 * Implemented the channel list sending in the WHOIS command reply
4351 in server and in the client.
4353 Implemented the channel list displaying on the user interface
4354 as well. Affected file silc/client_ops.c.
4356 * Added silc_channel_payload_parse_list to parse list of Channel
4357 Payloads. It returns SilcDList list of SilcChannelPayloads.
4358 Client for example can use this function to parse the list of
4359 channels it receives in the WHOIS command reply. The caller
4360 must free the list by calling silc_channel_payload_list_free.
4361 Affected files lib/silccore/silcchannel.[ch].
4363 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Added one new argument <user mode> to the WHOIS command reply
4366 to return the mode of the user in SILC. Updated the protocol
4369 Implemented it to the server and client.
4371 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Fixed the mode printing on the user interface on joining.
4374 Affected file silc/client_ops.c.
4376 * Implemented the UMODE command and user modes in general to the
4377 client library and to the user interface.
4379 * Implemented the UMODE command to the server.
4381 * The server now sends UNKNOWN_COMMAND error status if client sends
4382 unknown command. Affected file silcd/command.c.
4384 * All server commands now handle the command identifier the right
4385 way when sending the command reply to the client. The client can
4386 use to identify the command replies with the identifier.
4388 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Added silc_server_get_client_route to resolve the route to
4391 the client indicated by the client ID. Affected file is
4394 * Added silc_server_relay_packet as general function to relay
4395 packet to arbitrary destination. This deprecates functions
4396 like _send_private_message_key, _relay_notify etc. Affected
4397 file is silcd/packet_send.[ch].
4399 Removed silc_server_send_key_agreement,
4400 silc_server_send_private_message_key and
4401 silc_server_packet_relay_notify functions from the file
4402 silcd/packet_send.[ch].
4406 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4407 server. Affected file silcd/packet_receive.[ch].
4409 * Implemented the KILL command to the client. Implemented the
4410 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4411 Affected files lib/silcclient/command[_reply].c and
4412 lib/silcclient/client_notify.c. Implemented the KILL notify
4413 printing in the user inteface.
4415 * Fixed a lot silc_parse_nick memory leaks from the client
4416 library in the file lib/silcclient/command.c.
4418 * Changed the silc_server_send_notify_on_channels's `sender'
4419 argument from SilcSocketConnection to SilcClientEntry to
4420 check the sender as entry and not as connection object and not
4421 to send to the client provided as argument. The affected file
4422 is silcd/packet_send.[ch].
4424 * The notify packets that are destined directly to the client used
4425 to not to be processed by the server. Now changed that and the
4426 server processes all notify packets. After relaying the packet
4427 to the client the notify packet is processed in the server.
4429 * The silc_server_free_client_data now checks whether there is
4430 pending outgoing traffic for the client and purges the data to
4431 the network before removing the client entry.
4433 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4435 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4436 an client is killed from the SILC Network. Updated the protocol
4439 Added new function silc_server_send_notify_killed to the
4440 silcd/packet_send.[ch].
4442 * Added function silc_server_packet_relay_notify to relay notify
4443 packets that are destined directly to a client. In this case
4444 the server does not process the notify packets but merely relays
4445 it to the client. Affected file silcd/packet_send.[ch].
4447 Added also silc_server_packet_process_relay_notify to check
4448 whereto relay the notify. Affected file is
4449 silcd/packet_receive.[ch].
4451 * Implemented the KILL command to the server.
4455 * Added the backup schema desgined last fall to the protocol
4456 specs for everyone to see. The specification is in the
4457 *-spec-xx.txt draft and the packet type definitions for the
4458 backup routers is in *-pp-xx.txt draft. Thusly, added also
4459 new packet type SILC_PACKET_CELL_ROUTERS.
4461 * A big security problem in the implementation discovered. The
4462 signoff of an client did not cause new channel key generation
4463 which it of course should've done. The channel keys must be
4464 always re-generated when client leaves (or signoffs) the channel.
4465 The silc_server_remove_from_channels funtion now handles
4466 the channel key re-generation.
4468 * Added `sender' argument to the silc_server_send_notify_on_channels
4469 to not to send the client provided as argument. Affected file
4470 silcd/packet_send.[ch].
4472 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Implemented OPER and SILCOPER commands into the server and
4477 * Added silc_auth_verify and silc_auth_verify_data to verify
4478 the authentication directly from the authentication payload.
4479 It supports verifying both passphrase and public key based
4480 authentication. Affected file lib/silccore/silcauth.[ch].
4482 * Added `hash' field to the SilcIDListData structure. It is the
4483 hash negotiated in the SKE protocol. Affected file is
4486 * Slight redesigning of the SilcAuthPayload handling routines.
4487 Do not send SilcPKCS but SilcPublicKey as argument.
4489 * Implemented the public key authentication support to the
4490 serverconfig. The public key is loaded from the provided path
4491 and saved as authentication data to void * pointer. Thus,
4492 changed the unsigned char *auth_data to void *auth_data;
4494 * Fixed SHUTDOWN command to send the reply before the server
4495 is shutdown. :) Affected file silcd/command.c.
4497 * Fixed fatal bug in CONNECT command. The hostname was invalid
4498 memory and server crashed. Affected file silcd/command.c.
4500 * Fixed fatal bug in CLOSE command. The server_entry became
4501 invalid but was referenced later in the command. Affected file
4504 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Fixed fatal bug in failure packet handling. Server ignored
4507 the failure and thus crashed when it came.
4511 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4514 that the command may be executed only once in (about) 2 seconds.
4515 The old SILC_CF_LAG flag is same but allows command bursts up
4516 to five before limiting.
4518 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4519 server code. Various commands now includes the CF_LAG_STRICT
4520 flag to disallow any kind of miss-use of the command.
4522 * Fixed the silc_buffer_unformat to not to allocate any data
4523 if the length of the data is zero. It used to allocate the
4524 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4526 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Changed the format of AdminConnection configuration section
4529 in the server. Added username of the admin to the format.
4530 Affected files silcd/serverconfig.[ch].
4532 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4533 to return admin configuration data by host, username and/or
4536 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Implemented WHOWAS command to the server. Added the functions:
4540 silc_server_command_whowas_parse,
4541 silc_server_command_whowas_send_reply,
4542 silc_server_command_whowas_from_client and
4543 silc_server_command_whowas_from_server
4545 * Added <Client ID> argument to the WHOWAS command reply. Updated
4546 the protocol specs accordingly.
4548 * Implemented WHOWAS command and command_reply to the client
4551 Implemented the WHOWAS printing on the user interface.
4553 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Added new argument to the WHOWAS command reply, the real name.
4556 It is an optional argument. Updated the protocol specs.
4558 * Added SilcIDCacheDestructor callback that is registered when
4559 the SilcIDCache is allocated. The callback is called when
4560 an cache entry in the ID Cache expires, or is purged from the
4561 cache. Added into lib/silccore/idcache.[ch].
4563 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4564 to destruct the client entries when the cache entry expires.
4565 Other ID Cache's in server and in the client library ignores
4568 * If the ID Cache entry's `expire' field is zero then the entry
4569 never expires. Added boolean `expire' argument to the
4570 silc_idcache_add function in the lib/silccore/idcache.[ch].
4571 If it is TRUE the default expiry value is used.
4573 * Added silc_server_free_client_data_timeout that is registered
4574 when client disconnects. By default for 5 minutes we preserve
4575 the client entry for history - for WHOWAS command.
4577 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Added support to the server to enforce that commands are not
4580 executed more than once in 2 seconds. If server receives
4581 commands from client more frequently, timeout is registered
4582 to process the commands. Affected file silcd/command.c.
4583 Added new function silc_server_command_process_timeout.
4585 * Changed NICK_NOTIFY handling in client library to check that
4586 if the client's nickname was changed, so there is no need to
4587 resolve anything from the server.
4589 * Removed error printing from the WHOIS and IDENTIFY commands.
4590 If error occurs then it is ignored silently in the client library.
4591 The application, however, may map the received error to
4592 human readable error string. The application currently maps
4593 the NO_SUCH_NICKNAME error to string.
4595 * Made the command status message public to the application. Moved
4596 them from lib/silcclient/command_reply.c to
4597 lib/silcclient/command_reply.h. The application can map the
4598 received command status to the string with the
4599 silc_client_command_status_message function.
4601 * Added check to the server to check that client's ID is same
4602 as the Source ID in the packet the client sent. They must
4605 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Added dist-bzip hook to the Makefile.am to make bzip2
4608 compressed distributions.
4610 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Server now enforces the maximum length for the nickname and
4613 the channel as protocol specification dictates. 128 bytes for
4614 nickname and 256 bytes for channel name.
4616 * Moved the WHOIS printing to the application. The client libary
4617 does not print out the WHOIS information anymore, the application
4618 must do it. Renamed silc_client_command_reply_whois_print to
4619 the silc_client_command_reply_whois_save.
4621 The client's idle time is also sent to the application now, and
4622 the idle is shown on screen.
4624 * Added silc_client_command_reply_identify_save to save the
4625 received IDENTIFY entries.
4627 * Do not check for channel private keys in message sending and
4628 reception if the channel does not have the PRIVKEY mode set.
4629 Affected file lib/silclient/client_channel.c.
4631 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4634 just surfaced after chaning the JOIN procedure.
4636 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Added silc_client_get_clients_by_list to get client entries
4639 from Client ID list, that is returned for example by JOIN
4640 and USERS command replies. The application should use this
4641 function for example when JOIN command reply is received to
4642 resolve the clients already on the channel (library does not
4643 do that anymore as USERS command reply is not used in the JOIN
4644 procedure anymore). Affected files lib/silcclient/silcapi.h and
4645 lib/silcclient/idlist.c.
4647 * JOIN command reply and USERS command reply returns now SilcBuffer
4648 pointers instead of unsigned char pointers when returning
4649 the client list and mode list.
4651 * Added <Client ID> argument to the JOIN command reply, mainly
4652 for the server to identify for which client the command was
4653 originally sent. Updated protocol specs accordingly.
4655 * Added SilcDlist private_key pointer to the SilcChannelEntry
4656 in the client to support the channel private keys. Affected
4657 file is lib/silcclient/idlist.h.
4659 * Added SilcChannelPrivateKey argument to the function
4660 silc_client_send_channel_message so that application can choose
4661 to use specific private ke if it wants to. If it is not provided,
4662 the normal channel key is used, unless private keys are set.
4663 In this case the first (key that was added first) is used
4664 as the encryption key.
4666 * Implemented the support for channel private key handling.
4667 Implemented the following functions:
4669 silc_client_add_channel_private_key,
4670 silc_client_del_channel_private_keys,
4671 silc_client_del_channel_private_key,
4672 silc_client_list_channel_private_keys and
4673 silc_client_free_channel_private_keys
4675 Affected file lib/silcclient/client_channel.c.
4677 * Added the support for the private keys in the channel message
4678 sending and encryption and in the message reception and
4679 decryption. Affected funtions are
4680 silc_client_send_channel_message and silc_client_channel_message.
4682 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Added SKE's key verify callback to the client library's
4685 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4687 * Removed the statement that server (or router) must send USERS
4688 command reply when joining to the channel so that the client
4689 knows who are on the channel. Instead, the client list and
4690 client's mode list is now sent in the JOIN command reply to the
4691 client who joined channel. This is better solution.
4693 * Added function silc_server_get_users_on_channel and function
4694 silc_server_save_users_on_channel to the silcd/server.[ch].
4696 * Removed function silc_server_command_send_users from the
4699 * Do not show topic on the client library anymore. The topic is
4700 sent in the command reply notify to the application and the
4701 application must show the topic now.
4703 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Added client searching by nickname hash into the IDENTIFY and
4706 WHOIS commands in the server as they were clearly missing from
4707 them. Affected file is silcd/command.c.
4709 * Fixed a bug in private message receiving in the client library.
4710 The remote ID was freed and it wasn't supposed, now it is
4713 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Minor fix to the channel payload; allocate the data area, as it
4716 needs to be of specific length.
4718 * If the key agreement port is zero then the operating
4719 system will define the bound port. Affected files are
4720 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4722 * Added new function silc_channel_payload_decrypt into the file
4723 lib/silccore/silcchannel.[ch].
4725 * Moved the channel message etc, check from silc_packet_decrypt
4726 to applications. The library calls now a generic
4727 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4728 when the packet is either normal or special. This was done to
4729 allow more wide range of checking that was not allowed when
4730 the code was in library. Now applications can do virtually any
4731 checks to the packet and return to the library the decision how
4732 the packet should be processed. Affected files are
4733 lib/silccore/silcpacket.[ch].
4735 Added silc_server_packet_decrypt_check to the server and
4736 silc_client_packet_decrypt_check to the client library.
4738 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4739 to send with specified source and destination information.
4741 * Channel message delivery between routers was broken after the
4742 channel key distribution was fixed earlier. The channel key
4743 was used be to distributed to other routers as well which is not
4744 allowed by the protocol. Now this is fixed and channel keys
4745 really are cell specific and the channel message delivery between
4746 routers comply with the protocol specification.
4748 * Fixed various commands in server to check also the global list
4749 for the channel entry and not just the local list. The affected
4750 file silcd/command.c.
4752 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4754 * Added assert()s to buffer formatting and unformatting routines
4755 to assert (if --enable-debug) when error occurs. Affected
4756 file: lib/silcutil/silcbuffmt.c.
4758 * Changed to auto-reconnect to check whether the remote host is
4759 router and register the re-connect timeout if it is. It used
4760 to check that whether we are normal server, but router must do
4761 auto-reconnect with another router as well. Affected file
4764 * Removed the [<key len>] option from CMODE command as the cipher
4765 name decides the key length, nowadays. See the defined ciphers
4766 from the protocol specification.
4768 * Added [<hmac>] option to the CMODE command to define the HMAC
4769 for the channel. Added SILC_CMODE_HMAC channel mode.
4771 * Added [<hmac>] option for the JOIN command so that user can
4772 select which HMAC is used to compute the MACs of the channel
4775 * Added Hmac field to the Channel Message Payload. The integrity
4776 of plaintext channel messages are now protected by computing
4777 MAC of the message and attaching the MAC to the payload. The
4778 MAC is encrypted. Now, it is clear that this causes some
4779 overhead to the size of the packet but rationale for this is that
4780 now the receiver can verify whether the channel message decrypted
4781 correctly and also when private keys are set for the channel the
4782 receiver can decrypt the packet with several keys and check from
4783 the MAC which key decrypted the message correctly.
4785 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4786 lib/silccrypt/silccipher.[ch].
4788 * Added silc_hash_len to return the digest length into the
4789 lib/silcrypt/silchash.[ch].
4791 * Rewrote parts of Silc Channel Payload interface in the
4792 lib/silccore/silcchannel.[ch]. The encode function now also
4793 encrypts the packet and parse function decrypts it.
4795 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Fixed a minor formatting bug in the SKE's key material processing.
4798 It actually might have processed the keys wrong way resulting
4801 * Redefined the mandatory HMAC algorithms and added new algorithms.
4802 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4803 and hmac-md5 truncated to 96 bits. The mandatory is now
4804 hmac-sha1-96. Rest are optional (including the one that used
4805 to be mandatory). Rationale for this is that the truncated HMAC
4806 length is sufficient from security point of view and can actually
4807 make the attack against the HMAC harder. Also, the truncated
4808 HMAC causes less overhead to the packets. See the RFC2104 for
4811 * Added new [hmac] configuration section. The SKE used to use
4812 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4813 is of course wrong. The official names that must be proposed in
4814 the SKE are the ones defined in the protocol specification
4815 (hmac-sha1-96 for example). The user can configure any hmac
4816 using any hash function configured in the [hash] section. At
4817 least, the mandatory must be configured.
4819 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4821 * Added HMAC list to the SKE proposal list. It has now both
4822 hash algorithm list and HMAC list. This makes the protocol
4823 incompatible with previous versions. The SKE now seems to work
4824 the way it is supposed to work, for the first time actually.
4826 * Defined plain Hash algorithms to the protocol specification.
4829 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Implemented support for key agreement packets into the server.
4832 Added functions silc_server_key_agreement and
4833 silc_server_send_key_agreement. Other than these functions,
4834 server has nothing to do with this packet.
4836 * Added support for private message key packets into the server.
4837 Added functions silc_server_private_message_key and
4838 silc_server_send_private_message_key.
4842 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4843 called in the protocol's final callback instead in the END
4844 protocol state. This makes a little more sense and in the same
4845 time in client we can use the same protocol routines for normal
4846 key exchange and to key agreement packet handling as well.
4848 * Added to both client's and server's KE protocol context the
4849 SilcSKEKeyMaterial pointer to save the key material. We will
4850 bring the key material to the protocol's final callback by doing
4851 this. The final callback must free the key material.
4853 * Added SKE's packet_send callback into client's KE protocol
4854 context so that the caller can choose what packet sending function
4855 is used. This way we can use different packet sending when
4856 doing normal SKE when doing key agreement packet handling (in
4857 the key agreement packet handling we do not want to encrypt
4860 * Implemented the responder side of the key agreement routines
4861 in the client. The client can now bind to specified port and
4862 accept incoming key negotiation. The key material is passed
4863 to the application after the protocol is over.
4865 * Implemented the processing of incoming Key Agreement packet
4866 in the client. Added function silc_client_key_agreement to
4869 * Implemented the intiator side of the key agreement routines
4870 in the client. The client can now initiate key agreement with
4871 another remote client. The key material is passed to the
4872 application after the protocol is over.
4874 * Created client_keyagr.c to include all the key agreement
4877 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4878 SILC_TASK_CALLBACK except that it is not static.
4880 * Created client_notify.c and moved the Notify packet handling
4881 from the client.[ch] into that file.
4883 * Created client_prvmsg.c and moved all private message and
4884 private message key routines from the client.[ch] into that file.
4886 * Create client_channel.c and moved all channel message and
4887 channel private key routines from the client.[ch] into that file.
4889 * Changed silc_client_get_client_by_id_resolve to resolve with
4890 WHOIS command instead of IDENTIFY command, in the file
4891 lib/silclient/idlist.c.
4893 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Implemented the SKE's responder side to the Client library.
4897 * When FAILURE is received to the protocol do not trust it
4898 blindly. Register a timeout to wait whether the remote closes
4899 the connection as it should do it, only after that process the
4900 actual failure. This was changed to both client and server.
4902 * Added client_internal.h to include some of the structures
4903 there instead of client.h in lib/silcclient/.
4905 * Added function silc_task_unregister_by_callback to unregister
4906 timeouts by the callback function.
4908 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Some "Incomplete WHOIS info" errors has been appearing on the
4911 log files. Took away the entry->userinfo check from WHOIS
4912 reply sending. The entry->userinfo is now " " if client did not
4913 provide one. I thought this was fixed earlier but something
4914 is wrong still. Let's see if the error still appears.
4916 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * Fixed a minor bug in the login when the channel key is
4919 re-generated in the server. It used to generate the key in
4920 wrong order and thus caused problems in the channel traffic.
4922 * Fixed a minor bug in channel key distsribution after
4923 KICK command. The key was not sent to the router even though
4926 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Added silc_ske_process_key_material_data as generic routine
4929 to process any key material as the SILC protocol dictates. The
4930 function is used by the actual SKE library but can be used by
4931 applications as well. This relates to the private message keys
4932 and the channel private keys since they must be processed the
4933 same way the normal SILC session keys. The protocol dictates
4934 this. Affected files: lib/silcske/silcske.[ch].
4936 Added also silc_ske_free_key_material to free the
4937 SilcSKEKeyMaterial structure.
4939 * Defined silc_cipher_set_key function to set the key for
4940 cipher without using the object's method function. The affected
4941 files: lib/silccrypt/silccipher.[ch].
4943 * Implemented silc silc_client_add_private_message_key,
4944 silc_client_add_private_message_key_ske,
4945 silc_client_del_private_message_key,
4946 silc_client_list_private_message_keys and
4947 silc_client_free_private_message_keys functions in the
4950 Added functions silc_client_send_private_message_key to send
4951 the Private Message Key payload and silc_client_private_message_key
4952 to handle incoming Private Message Key payload.
4954 * Added Cipher field to the Private Message Key payload to set
4955 the cipher to be used. If ignored, the default cipher defined
4956 in the SILC protocol (aes-256-cbc) is used.
4958 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Removed lib/silcclient/ops.h file.
4962 Redefined parts of the SILC Client Library API. Created new
4963 file silcapi.h that deprecates the ops.h file and defines the
4964 published Client Library API. Defined also private message key
4965 API and channel private key API into the file.
4967 This is the file that the application must include from the
4968 SILC Client Library. Other files need not be included by
4969 the application anymore.
4971 * Added new key_agreement client operation callback and also
4972 defined the Key Agreement library API for the application.
4974 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4977 is used by clients to request key negotiation between another
4978 client in the SILC network. If the negotiation is started it
4979 is performed using the SKE protocol. The result of the
4980 negotiation, the secret key material, can be used for example
4981 as private message key.
4983 Implemented the Key Agreement payload into the files
4984 lib/silccore/silauth.[ch].
4986 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Redefined ciphers for the SILC protocol. Added some new ciphers
4989 and defined the key lengths for the algorithms. Changed the
4990 code accordingly. The default key length is now 256 bits.
4992 * Fixed SKE key distribution function silc_ske_process_key_material
4993 when the key length is more than 128 bits. The default key
4994 length in SILC is now 256 bits.
4996 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4997 to indicate unsupported algorithm.
4999 * Renamed rijndael.c to aes.c and all functions as well.
5001 * Fixed a long standing channel key setting bug in client library.
5002 Weird that it has never surfaced before.
5004 * Fixed bug in channel deletion. If the entire channel is removed
5005 then it must also delete the references of the channel entry
5006 from the client's channel list as the client's channel entry and
5007 the channel's client entry share same memory.
5009 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Implemented CONNECT and SHUTDOWN commands in the client.
5013 * Implemented CLOSE command to the client.
5015 * Added the function silc_idlist_find_server_by_name into the
5016 files silcd/idlist.[ch].
5018 Added the function silc_idlist_find_server_by_conn into the
5019 files silcd/idlist.[ch].
5021 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * DIE command was renamed to SHUTDOWN. Updated the both code
5026 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5027 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5029 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5032 * Added function silc_server_create_connection function to create
5033 connection to remote router. My server implementation actually
5034 does not allow router to connect to normal server (it expects
5035 that normal server always initiates the connection to the router)
5036 so the CONNECT command is only good for connecting to another
5039 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5042 or some other client was kicked from the channel.
5044 Implemented the handling of the notify type to both client
5047 Implemented silc_server_send_notify_kicked to send the KICKED
5048 notify. It is used to send it to the server's primary router.
5050 * Implemented the KICK command into server and client.
5052 * Added `query' argument to the silc_idlist_get_client function
5053 to indicate whether to query the client from server or not if
5056 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5057 to indicate that the client is not channel founder.
5061 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Removed the rng context from SilcPacketContext structure and
5064 changed that the packet routine uses the Global RNG API.
5066 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Added support for quit message that client can "leave" on the
5069 channel when it quits the SILC. It is ditributed inside the
5070 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5072 Added silc_server_free_client_data that will take the
5073 signoff message as argument.
5075 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5077 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Updated parts of the protocol specification to keep it up
5082 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5085 payloads in one packet.
5087 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5088 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5089 use now the new List flag.
5091 * Also deprecated the following packet types: REPLACE_ID,
5092 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5094 * Added list support for Notify packet in server.
5096 * Added silc_server_send_notify_channel_change to send the
5097 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5098 the silc_server_send_replace_id.
5100 * Added silc_server_send_notify_nick_change to send the
5101 NICK_CHANGE notify type. Deprecates the function
5102 silc_server_send_replace_id.
5104 * Added silc_server_send_notify_join to send the JOIN notify type.
5105 Deprecates the function silc_server_send_new_channel_user.
5107 * Added silc_server_send_notify_leave to send LEAVE notify type.
5108 Deprecates the function silc_server_send_remove_channel_user.
5110 * Added silc_server_send_notify_cmode and
5111 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5112 types. Deprecates the silc_server_send_set_mode function.
5114 * Added SERVER_SIGNOFF notify type to indicate that server has
5115 quit. This means that all clients on the channel from that
5116 server will drop. This can be also used when netsplit happens.
5118 Deprecated REMOVE_ID packet type since it is not needed anymore
5121 Added silc_server_send_notify_server_signoff to send the
5122 SERVER_SIGNOFF notify type. Deprecates the function
5123 silc_server_send_remove_id.
5125 Added also silc_server_send_notify_signoff to send the
5126 SIGNOFF notify type.
5128 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5129 SILC protocol from this day on. Changed the protocol
5130 specification as well.
5132 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5133 notify type. It is used between routers to notify about
5134 topic changes on a channel.
5136 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5139 * Partly updated the protocol specification to comply with the
5140 changes now made. It is still though a bit outdated.
5142 * The JOIN notify type now takes one extra argument <Channel ID>.
5143 The packet used to be destined to the channel but now the
5144 JOIN type may be sent as list thus it is impossible to
5145 destine it to any specific channel. By adding this argument
5146 it is again possible.
5148 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Added CREDITS file. The CHANGES and CREDITS file will appear
5151 in the distribution as well.
5153 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5155 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5156 types in the server's silcd/packet_receive.c.
5158 * Implemented CMODE and CUMODE to work in router environment.
5160 * Fixed minor encoding and decoding buglet from the
5161 lib/silccore/silcmode.c.
5163 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5166 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5168 * Changed all SilcConfigServer* and silc_config_server* to
5169 SilcServerConfig* and silc_server_config*, respectively.
5172 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Associated the ID (client or server ID) to the Authentication
5175 Payload to avoid any possibility of forging. Updated the
5176 protocol specification and the code accordingly.
5178 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * The RSA key length is now save to the RsaKey context in the
5181 key generation process in lib/silccrypt/rsa.c. The key length
5182 is now used to figure out the maximum size of the block allowed
5183 to be encrypted/signed.
5185 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5186 is equivalent to the silc_mp_mp2bin but does not allocate any
5189 * Changed silc_mp_mp2bin API to take length argument. If it is
5190 non-zero then the buffer is allocated that large. If zero, then
5191 the size is approximated using silc_mp_sizeinbase, which however
5194 * Created Global RNG API which is global RNG that application can
5195 initialize. After initializing, any routine anywhere in the
5196 code (including library) can use RNG without allocating a new
5197 RNG object. This was done to allow this sort of use of the
5198 RNG in code that has no chance to allocate RNG object. All
5199 applications currently allocate this and many routines in the
5200 library use this. Affected file lib/silccrypt/silcrng.[ch].
5202 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5203 it to use the Global RNG API.
5205 * Defined Authentication Payload into protocol specification that
5206 is used during SILC session to authenticate entities. It is
5207 used for example by client to authenticate itself to the server
5208 to obtain server operator privileges.
5210 Implemented this payload into the lib/silccore/silcauth.[ch].
5211 Implemented also routines for public key based authentication
5212 as the new protocol specification dictates.
5214 Moved definitions of different authentication methods from
5215 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5217 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5218 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5219 silc_pkcs_verify_with_hash functions into the file
5220 lib/silccrypt/silcpkcs.[ch].
5222 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * The client entry's userinfo pointer must be always valid.
5225 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5226 will fail since it requires the userinfo. Now, the userinfo
5227 is allocated as "" if actual userinfo does not exist. Actually,
5228 it must exist and it is totally Ok to drop client connections
5229 that does not announce the userinfo. However, we will make
5230 this workaround for now.
5232 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5233 to return the remote port by socket.
5235 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5238 SILC_SERVER_PENDING_EXEC and added an new macro
5239 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5240 data or when error occurs while processing the pending command.
5242 Added new argument `destructor' into silc_server_command_pending
5243 and to the SilcServerCommandPending object. This destructor is
5244 now called after calling the pending callback or if error occurs
5245 immediately. If error occurs the actual pending callback won't
5246 be called at all - only the destructor. The destructor may be
5247 NULL if destructor is not needed.
5249 All this applies for client library code as well. Similar
5250 changes were made there as well for the pending commands.
5252 In the client, the application must now allocate the
5253 SilcClientCommandContext with the silc_client_command_alloc
5256 * Added reference counter to the SilcServerCommandContext. Added
5257 function silc_server_command_alloc and silc_server_command_dup
5260 Same type of functions added to the client library for the same
5263 * Removed the cmd_ident from IDListData away since it is now
5264 global for all connections. It is the command identifier used
5265 in command sending and with pending commands. The affected file
5268 * Added reference counter to the SilcSocketConnection objecet to
5269 indicate the usage count of the object. The object won't be
5270 freed untill the reference counter hits zero. Currently only
5271 server uses this, and client ignores it. The client must be
5272 set to use this too later. The affected files are
5273 lib/silccore/silcsockconn.[ch]. Added also the function
5274 silc_socket_dup to increase the reference counter.
5276 This was mainly added because it is possible that the socket
5277 is removed underneath of pending command or other async
5278 operation. Now it won't be free'd and proper DISCONNECTING
5279 flags, etc. can be set to avoid sending data to connection that
5280 is not valid anymore.
5282 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5283 the connection. After that it sets SILC_SET_DISCONNECTED.
5284 It is, however, possible that the socket data is not still freed.
5285 The silc_server_packet_process now checks that data is not
5286 read or written to connection that is DISCONNECTED. The socket
5287 get's freed when the reference counter hits zero.
5289 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Changed the client operation API: channel_message operation's
5292 `sender' is now the client entry of the sender, not the nickname
5293 and the `channel' is the channel entry, not the channel name.
5295 In the private_message operation the `sender' is now also the
5296 client entry of the sender not the nickname.
5298 Affected file is lib/silcclient/ops.h and all applications
5299 using the client operations.
5301 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Moved the calling of ops->connect() from connect_to_server_final
5304 into receive_new_id functin since that is the point when the
5305 client is actually allowed to send traffic to network. The
5306 affected file is lib/silcclient/client.c.
5308 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5311 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5312 (if needs broadcasting) instead of broadcasting the packets one
5313 by one which would make a burst in the network traffic.
5315 * Added `broadcast' argument to the functions in silcd/server.[ch]
5316 silc_server_create_new_channel[_with_id] to indicate whether
5317 to send New Channel packet to primary router.
5319 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Added new function into the silcd/server.[ch] files:
5322 silc_server_create_new_channel_with_id to create new channel with
5323 already existing Channel ID.
5325 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5326 lib/silccore/silcpacket.h. This packet is used t send list of
5327 Set Mode payloads inside one packet. Server uses this to set
5328 the modes for the channels and clients on those channels, that it
5329 announced to the router when it connected to it. The protocol
5330 specification has been updated accordingly.
5332 * The silc_server_new_channel did not handle the packet coming
5333 from normal server as it normally does not send that. However,
5334 when it announces its channels it does send it. Implemented
5335 the support for that.
5337 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5338 into the file lib/silccore/id.h.
5340 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Fixed memory leaks in the functions silc_idlist_del_client,
5343 silc_idlist_del_channel and silc_idlist_del_server in the file
5344 silcd/idlist.c. All of those leaked like a sieve.
5346 * Fixed some small memory leaks in the client's function
5347 silc_client_notify_by_server.
5349 * Added functions into silcd/server.c: silc_server_announce_clients,
5350 silc_server_announce_channels and silc_server_announce_server.
5351 These functions are used by normal and router server to announce
5352 to its primary router about clients, channels and servers (when
5353 router) that we own. This is done after we've connected to the
5356 These functions effectively implements the following packet types:
5357 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5358 and SILC_PACKET_NEW_ID_LIST.
5360 * Added new functions into the silcd/packet_receive.[ch]:
5361 silc_server_new_id_list, silc_server_new_channel_list and
5362 silc_server_new_channel_user_list to handle the incoming
5363 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5365 * Added support of changing Channel ID in the function
5366 silc_server_replace_id. If the server that announces a channel
5367 to the router already exists in the router (with same name but
5368 with different Channel ID), router is responsible to send
5369 Replace ID packet to the server and force the server to change
5370 the Channel ID to the one router has.
5372 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5373 client that the Channel ID has been changed by the router. The
5374 normal server sends this to the client. Client must start using
5375 the new Channel ID as the channel's ID.
5377 Implemented handling of this new type into lib/silcclient/client.c
5378 into the function silc_client_notify_by_server.
5380 * Added new function silc_idlist_replace_channel_id into the files
5381 silcd/idlist.[ch] to replace the Channel ID.
5383 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Call silc_server_command_identify_check always when processing
5386 the IDENTIFY command in silcd/command.c
5388 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5391 send keepalive packets. The packet can be sent by clients,
5392 servers and routers.
5394 Added function silc_socket_set_heartbeat into the file
5395 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5396 If not set, the heartbeat is not performed. The actual
5397 heartbeat is implemented in the low level socket connection
5398 library. However, application is responsible of actually
5401 Added silc_server_send_heartbeat to send the actual heartbeat
5402 packet into silcd/packet_send.[ch]. Server now performs
5403 keepalive with all connections.
5405 * Added silc_task_get_first function into lib/silcutil/silctask.c
5406 to return the timeout task with shortest timeout. There was a bug
5407 in task unregistration that caused problems. TODO has been
5408 updated to include that task system must be rewritten.
5410 * The client library will now resolve the client information when
5411 receiving JOIN notify from server for client that we know but
5412 have incomplete information.
5414 * Rewrote parts of silc_server_remove_from_channels and
5415 silc_server_remove_from_one_channel as they did not remove the
5416 channel in some circumstances even though they should've.
5418 * Encryption problem encountered in server:
5420 The LEAVE command used to send the Channel Key packet to the
5421 router immediately after generating it. However, the code
5422 had earlier sent Remove Channel user packet but not immediately,
5423 ie. it was put to queue. The order of packets in the router
5424 was that Channel Key packet was first and Remove Channel User
5425 packet was second, even though they were encrypted in the
5426 reverse order. For this reason, MAC check failed. Now, this
5427 is fixed by not sending the Channel Key packet immediately but
5428 putting it to queue. However, this is more fundamental problem:
5429 packets that are in queue should actually not be encrypted
5430 because packets that are sent immediately gets encrypted
5431 actually with wrong IV (and thus MAC check fails). So, packets
5432 that are in queue should be encrypted when they are sent to
5433 the wire and not when they put to the queue.
5435 However, the problem is that the current system has not been
5436 designed to work that way. Instead, the packet is encrypted
5437 as soon as possible and left to the queue. The queue is then
5438 just purged into wire. There won't be any fixes for this
5439 any time soon. So, the current semantic for packet sending
5442 o If you send packet to remote host and do not force the send
5443 (the packet will be in queue) then all subsequent packets to the
5444 same remote host must also be put to the queue. Only after the
5445 queue has been purged is it safe again to force the packet
5448 o If you send all packets immediately then it safe to send
5449 any of subsequent packets through the queue, however, after
5450 the first packet is put to queue then any subsequent packets
5451 must also be put to the queue.
5453 Follow these rules and everything works fine.
5455 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Added new function silc_server_remove_clients_by_server to
5458 remove all client entries from ID list when the server connection
5459 is lost. In this case it is also important to invalidate all
5460 client entires as they hold the invalid server entry. This
5461 fixes fatal bug when server has lost connection and will reconnect
5464 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Made some sanity checks to silc_server_daemonise like to check
5467 whether the requested user and group actually exists.
5469 * Added sanity check to SKE's silc_ske_responder_finish to check
5470 that the public and private key actually is valid.
5472 * Invalidate the client's nickname when receiving Replace ID
5473 packet and the Client ID is being replaced. This means that the
5474 server will query the nickname if someone needs it (client)
5477 * Sort the ID Cache in client library when the ID Cache data
5478 has changed (needs sorting).
5480 * Do not allow for SILC client to create several connections to
5481 several servers. The client does not support windows right now
5482 and generating multiple connections causes weird behaviour.
5484 Irssi-silc client does support windows and can handle several
5485 connections without problems, see: www.irssi.org and SILC plugin.
5487 * Fixed some places where client was added to the IDList. The
5488 rule of thumb is following (in order to get everything right):
5489 If the client is directly connected local client then the
5490 `connection' argument must be set and `router' argument must be
5491 NULL to silc_idlist_add_client function. If the client is not
5492 directly connected client then the `router' argument must
5493 bet set and the `connection' argument must be NULL to the
5494 silc_idlist_add_client function.
5496 * The funtion silc_server_packet_send_local_channel actually did
5497 not check whether the client was locally connected or not. It
5498 does that now. Fixed a bug related to LEAVE command.
5500 * Fixed Remove Channel User payload parsing bug in server's
5501 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5503 * The server's silc_server_save_channel_key now checks also the
5504 global ID list for the channel as it might not be in the local
5505 list. Fixed a bug related to LEAVE command.
5507 * Is this the end of the [<unknown>] buglet that has been lurking
5508 around for a long time? A little for loop fix in server's
5509 silc_server_command_whois_parse that is used by both IDENTIFY
5510 and WHOIS command. At least, this was a clear bug and a cause
5511 of one type of [<unknown>] buglet.
5513 * WHOIS and IDENTIFY commands call the function
5514 silc_server_command_[whois/identify]_check function even if
5515 we are not router server.
5517 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Added --with-gmp configuration option. If set the GMP
5520 is always compiled in the SILC source tree. If not set then
5521 it is checked whether the system has the GMP3 installed. If
5522 it has then the GMP won't be compiled (the system's headers
5523 and library is used), if it doesn't have it then the GMP is
5524 compiled in the SILC source tree.
5526 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5528 * Changed RSA private exponent generation to what PKCS #1
5529 suggests. We try to find the smallest possible d by doing
5530 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5531 not security fix but optimization.
5533 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Added new config entry [Identity] to fork the server and run
5536 it as specific user and group. A patch from Bostik.
5538 * Imported Dotconf configuration library into lib/dotconf.
5539 This will be used to create the SILC configuration files later.
5540 It will appear in the distsribution after this commit.
5542 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * A big code auditing weekend happening. Auditing code for
5545 obvious mistakes, bugs and errors. Also, removing any code
5548 Removed files for being obsolete:
5550 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5551 inline in the file lib/silcutil/silcbuffer.h)
5553 o lib/silcutil/silcbufutil.c (the header has inline versions)
5555 Changed code to fix possible error conditions:
5557 o The buffer formatting routines now check that the destination
5558 buffer really has enough space to add the data. This applies for
5559 both buffer formatting and unformatting
5560 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5561 unformatting was changed to accomodate following rules:
5562 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5563 sent to the function while XXX_*STRING will not allocate or copy
5564 the data into the buffer. Instead it sets the pointer from the
5565 buffer into the pointer sent as argument (XXX_*STRING used to
5566 require that the pointer must be allocated already). This change
5567 makes this whole thing a bit more consistent and more optimized
5568 (note that the data returned in the unformatting with XXX_*STRING
5569 must not be freed now). The routines return now -1 on error.
5571 o Tried to find all code that use buffer_format and buffer_unformat
5572 and added return value checking to prevent formatting and
5573 especially unformatting errors and possible subsequent fatal
5576 o Changed ske->x and ske->KEY to mallocated pointers in
5577 lib/silcske/silcske.h. Fixed possible data and memory leak.
5579 o Added return value checking to all *_parse* functions. Fixed
5580 many memory leaks as well.
5582 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5583 so that buffer overflows would not happen. All code now also
5584 checks the return value as it can fail.
5586 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Added reconnection support to server if the normal server looses
5589 its connection to the router (for example if router is rebooted).
5590 The server performs normal reconnection strategy implemented
5591 to the server. Affected file silcd/server.c.
5593 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Added new packet type SILC_PACKET_SET_MODE that is used to
5596 distribute the information about changed modes (for clients,
5597 channels and clients channel modes) to all routers in the
5598 network. Updated the protocol specification accordingly.
5600 Added functions into silcd/packet_send.c and
5601 silcd/packet_receive.c: silc_server_send_set_mode,
5602 silc_server_set_mode.
5604 Added new files silcmode.[ch] into lib/silccore that implements
5605 the encoding and decoding of Set Mode Payload. Added new type
5606 SilcSetModePayload. Moved the definitions of different modes
5607 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5609 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Oops, a little mistake in server's connection authentication
5612 protocol. The protocol is not ended with FAILURE but with
5613 SUCCESS if the authentication is Ok. :) Affected file is
5616 * Implemented NICK_CHANGE notify handling in server in the file
5617 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5618 the local clients on the channel. After the changing nickname
5619 in router environment snhould work and the [<unknown>] nickname
5620 should appear no more.
5622 The silc_server_replace_id function that receives the Replace ID
5623 payload now sends the NICK_CHANGE notify type also in the file
5624 silcd/packet_receive.c
5626 * Changed WHOIS and IDENTIFY command to support the maximum amount
5627 of arguments defined in protocol specs (3328 arguments). This
5628 fixed a bug that caused problems when there were more than three
5631 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Added extra parameter, command identifier, to the
5634 silc_client_send_command so that explicit command identifier
5637 Changed that ID list routines uses specific command identifier
5638 when sending WHOIS/IDENTIFY requests to the server so that they
5639 can be identified when the reply comes back.
5641 Affected files lib/silcclient/command.[ch],
5642 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5644 * Added `sender' argument to silc_server_packet_send_to_channel
5645 to indicaet the sender who originally sent the packet to us
5646 that we are now re-sending. Ignored if NULL. Affected file
5647 silcd/packet_send.[ch].
5649 * Added some server statistics support in silcd/server_internal.h
5650 SilcServerStatistics structure and around the server code. Also
5651 send some nice statistics information when client is connecting
5654 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5656 * Fixed channel ID decoding in server's JOIN command reply in
5657 silcd/command_reply.c
5659 * Fixed braodcasting of replace ID payload to not to send it if
5660 we are standalone server in silcd/packet_receive.c.
5662 * Fixed all channel message sending routines to not to send
5663 packets to clients that has router set, since they are routed
5664 separately in the same function earlier. Affects file
5665 silcd/packet_send.c and all channel packet sending functions.
5667 * In USERS reply, res_argv[i] are not allocated, the table
5668 is allocated. Thus changed that free the table, not its
5671 * In server's whois_check and identify_check if the client is
5672 locally connected do not send any WHOIS commands - they are not
5675 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * Fixed some minor bugs in client when sending WHOIS command. The
5678 arguments was in wrong order.
5680 * Removed statis function add_to_channel from server in
5681 silcd/command.c that was previously used with the joining but
5684 * Tested USERS command in router environment successfully with two
5685 routers, two servers and two clients.
5687 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5689 * Reorganized the USERS command and command reply in client library
5690 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5691 When the command is given by user we register a pending command
5692 callback that will reprocess the command after the reply has been
5693 received from the server. When reprocessing the packet we then
5694 display the information. Thus, the USERS information is displayed
5695 now in the command callback instead of in the command reply
5696 callback. The processing of the command is same as previously
5697 when server has sent the command reply in the JOINing process.
5699 * Added to USERS command in silcd/command_reply.c to join the client,
5700 we didn't use to know about, to the channel after we've created
5701 a client entry for it. Also, for clienet we did know already still
5702 check whether it is on the channel or not and add it if not.
5704 * Removed silc_server_command_join_notify as the function and its
5707 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Changed the client's pending command handling to the same as the
5710 server's pending command handling. It is also now possible to
5711 execute command reply functions from other command reply
5712 function as the function callbacks for commands and command
5713 replies are one and same. The pending commands are not static
5714 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5715 in client connection context. Thus, pending commands are server
5716 connection specific as it is convenient.
5718 Changed the function silc_client_command_pending and
5719 silc_client_command_pending_del and added new function
5720 silc_client_command_pending_check. Removed the
5721 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5724 * Added cmd_ident, current command identifier, to the client
5725 connection context in lib/silcclient/client.h to keep track on
5726 command identifiers used in command sending. Client's command reply
5727 function handling now supports the mandatory command identifiers.
5729 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5730 funtions in client to fully support pending command callbacks.
5732 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5733 as one of the arguments to the application in the command reply
5736 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5737 before first releasing SILC but came back. Now it is removed again
5738 and should come back nomore. The FORWARDED flag was used only
5739 by the JOINing procedure by forwarding the command packet to router.
5740 Now, the JOINing procedure has been changed to more generic (due
5741 to various router environment issues) and FORWARDED is not needed
5742 anymore for anything. The protocol specification is yet to be
5745 Now, removed silc_server_packet_forward from server and the flag
5746 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5748 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5750 * Renamed NAMES command to USERS command. The NAMES was named that
5751 due to historical reasons. Now it is renamed. Also, rewrote
5752 parts of the USERS command. The nickname list is not sent anymore
5753 by the server. Only Client ID and mode lists are sent in the USERS
5754 command. Changed this also to the protocol specification.
5756 The client now resolves the names and stuff after it receives
5757 the USERS list from the server when joining to the channel.
5759 * WHOIS and IDENTIFY commands has been changed to support multiple
5760 Client ID's per command. One can now search for multiple users
5761 in the network by sending only one WHOIS or IDENTIFY command.
5762 Changed the code and the protocol specifications.
5764 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5765 uses silc_server_command_whois_parse to parse the request. */
5767 * If normal server, do not parse the WHOIS and IDENTIFY requests
5768 before sending it to the router. Saves some time.
5770 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5772 * Fixed JOIN command on client library. Wrong number of arguments
5773 used to crash the client.
5775 * Added silc_server_channel_has_global function to check whether
5776 channel has global users or not.
5778 * Added silc_server_channel_has_local function to check whether channel
5779 has locally connected clients on the channel.
5781 * The silc_server_remove_from_one_channel now checks whether the
5782 channel has global users or not after given client was removed from
5783 the channel. It also checks whether the channel has local clients
5784 on the channel anymore. If it does not have then the channel entry
5785 is removed as it is not needed anymore.
5787 * The silc_server_notify now checks on JOIN notify whether the joining
5788 client is one of locally connected or global. If it is global then
5789 the channel has now global users on the channel and that is marked
5790 to the channel entry. Also, it now saves the global client to
5791 global list who is joining and JOINs it to the channel. This is
5792 for normal server, that is.
5794 Changed silc_server_send_notify_on_channel,
5795 silc_server_packet_relay_to_channel and
5796 silc_server_packet_send_to_channel check if we are normal server
5797 and client has router set (ie. global client) do not send the
5798 message to that client, as it is already routed to our router.
5800 * Implemented LEAVE notify type handling in silc_server_notify
5803 * Tested LEAVE command in router environment successfully. Tested
5804 with two routers, two servers and two clients.
5808 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5810 * Implemented SIGNOFF notify type handling in silc_server_notify
5813 * silc_server_remove_id now removes the client entry from all channels
5814 it has joined and thusly sends SIGNOFF notify type.
5816 * Rewrote the NAMES list generation in server by removing two excess
5817 loops. The lists are created now inside one loop.
5819 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * silc_server_remove_channel_user checks now also global list
5822 for channel and client.
5824 * silc_server_new_channel_user checks now both local and global
5825 list for channel and client. Fixed a bug in client id decoding.
5826 Used to decode wrong buffer.
5828 * silc_server_channel_message checks now both local and global
5829 list for channel entry.
5831 * Tested channel joining (hence JOIN) in router environment
5832 successfully. Tested with two routers, two servers and two
5835 * Tested channel message sending in router environment successfully.
5837 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * Added silc_server_save_channel_key into server.[ch] to save the
5840 received channel key in Channel Key payload processing. It is
5841 also used in JOIN command reply handling.
5843 Equivalent function silc_client_save_channel_key added into
5844 client.[ch] into client library.
5846 * Changed JOIN command reply to send information whether the channel
5847 was created or not (is existing already) and the channel key
5848 payload. Changed protocol specs accordingly.
5850 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5851 the request was sent by ID and not by nickname. Crashed on
5854 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5856 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5857 now correctly save the received data.
5859 * silc_server_free_sock_user_data now notifies routers in the
5860 network about entities leaving the network.
5862 At the same time implemented functions silc_server_remove_id
5863 and silc_server_send_remove_id to receive and send REMOVE_ID
5864 packets. The packet is used to notify routers in the network
5865 about leaving entities. The ID removed will become invalid in
5868 * Added function silc_idlist_del_server into server. Removes and
5869 free's server entry from ID list.
5871 * silc_server_private_message function now checks, if we are router,
5872 that the destination ID really is valid ID, naturally.
5874 * In router when NEW_ID packet is received (for new client) the
5875 hash of the Client ID is saved in the ID Cache but the
5876 client->nickname is set to NULL, instead of putting the hash
5879 IDENTIFY command now also checks that client->nickname must be
5880 valid. If it is not if will request the data from the server who
5881 owns the client. Added new function
5882 silc_server_command_identify_check.
5884 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5885 to set the command to already allocated Command Payload.
5887 * Tested private message sending in router environment with two
5888 routers, two servers and two clients. Fixed minor bugs and now
5891 * Fixed segfault from client's NAMES command. Used to crash if
5894 * Forwarded packets must not be routed even if it is not destined
5895 to the receiver. Changed server code comply with this.
5897 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Added `require_reverse_mapping' boolean value to ServerParams
5900 structure. If TRUE (not default) the server will require that
5901 the connecting host has fully qualified domain name.
5903 If the reverse mapping is not required and hostname could not be
5904 found the IP address is used as hostname.
5906 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Implemented version string checking to both client and server.
5909 The check is incomplete currently due to the abnormal version
5910 strings used in development version of SILC.
5912 * Changed all command functions in server to use the new
5915 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * Changed char *data to unsigned char *data in ID Cache system to
5918 support binary data as ID Cache data. Changed code to support
5919 binary data in lib/silccore/idcache.c.
5921 * Renamed silc_server_packet_relay_command_reply to
5922 silc_server_command_reply as it is normal packet receiving
5923 function. Rewrote the function to accept command replys for
5924 servers and not only for clients.
5926 * Mark remote router always as registered server if we are connecting
5927 to it. Otherwise, commands sent by the router to us are ignored.
5929 * All ID List find routines now returns the ID Cache Entry pointer
5930 as well if requested.
5932 * WHOIS command works now in router environment, tested with two
5933 routers, two servers and two clients.
5935 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5936 in router environment (as it is almost equivalent to WHOIS) but
5937 hasn't been tested thoroughly. Added new functions:
5939 silc_server_command_identify_parse
5940 silc_server_command_identify_send_reply
5941 silc_server_command_identify_from_client
5942 silc_server_command_identify_from_server
5944 * Disabled route cache adding because adding two different ID's with
5945 same IP replaces the old cache entry thus giving wrong route.
5946 The entry->router->connection is always the fastest route anyway
5947 so route cache may not be needed. Of course, new routes maybe
5948 established after receiving the ID when the entry->router->connection
5949 might not be anymore the most optimal.
5951 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5953 * Add route cache for received ID for fast routing.
5955 * Added silc_server_packet_route to route received packet on router
5956 that is not destined to us.
5958 * Renamed silc_server_get_route to silc_server_route_get.
5960 * Added id_string and id_string_len fields into SilcServer to
5961 include encoded ServerID for fast comparing without excess
5962 encoding of the ID's.
5964 * Cleaned up WHOIS command on server side. Added following static
5967 silc_server_command_whois_parse
5968 silc_server_command_whois_check
5969 silc_server_command_whois_send_reply
5970 silc_server_command_whois_from_client
5971 silc_server_command_whois_from_server
5973 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5974 arguments in command replies. All command functions should be
5975 updated to use this macro.
5977 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * Minor typo fixes on command reply handling on server.
5981 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5983 * Added silc_server_command_add_to_channel internal routine to add
5984 the client to the channel after router has created the channel and
5985 sent command reply to the server.
5987 * Added generic silc_server_send_command to send any command from
5990 * Use static buffer with ID rendering instead of duplicating data.
5992 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Fixed a channel user mode bug when joining to a channel server gave
5995 everybody channel founder rights, oops.
5997 * We mark ourselves as the router of the incoming server connection
5998 if we are router ourselves. This way we can check in some packet
5999 sending functions whether it is locally connected server. For
6000 incoming router connections we put NULL.
6002 * For router sending packets locally means now always sending the
6003 packet cell wide; to local clients and local servers. For normal
6004 server sending packet locally means sending it to only local
6007 * Fixed the JOIN command to really work in router environment. If the
6008 channel is created it is always created by the router. Router is
6009 also responsible of making the initial joining to the channel,
6010 sending JOIN notify to the sending server and distributing
6011 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6012 does not exist server doesn't do anything else but forward the
6013 command to the router which performs everything.
6015 * Added silc_server_send_channel_key function to send the Channel Key
6018 * Added silc_server_create_channel_key to create new channel key. The
6019 channel key is now re-generated everytime someone joins or leaves
6020 a channel, as protocol dictates. Note: channel->key_len is the
6023 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6026 packet_receive.[ch] to separate packet sending and receiving
6027 routines. The server.[ch] now includes everything else including
6028 actual packet processing (writing and reading data) and other
6031 Renamed silc_server_private_message_send_internal to
6032 silc_server_send_private_message. The routine is still though
6033 used only to relay private messages as server does not send
6034 private messages itself.
6036 Renamed silc_server_new_channel to silc_server_create_new_channel
6037 and added new function sicl_server_new_channel that handles the
6038 incoming New Channel packet. Added also new sending function
6039 silc_server_send_new_channel to send New Channel Payload.
6041 * Added new function silc_server_notify to process incoming notify
6042 packet to the server/router. Server may then relay the notify
6043 to clients if needed.
6045 * Added new function silc_server_new_channel_user to process incoming
6046 New Channel User packet. Router will redistribute the packet and
6047 send JOIN notify to its local clients and locally connected servers
6048 if needed. Normal server will send JOIN notify to its local client
6049 on same channel when received this packet. Added also corresponding
6050 sending function silc_server_send_new_channel_user to sent the
6053 * Added boolean route argument to send_notif_to_channel and
6054 packet_send_to_channel functions to attempt to route the packet
6055 if it is TRUE and send only locally if it is FALSE.
6057 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * silc_server_replace_id now broadcasts the received replace ID
6060 packet if it is not broadcast packet already. The router must
6061 broadcast to inform other routers about changed ID.
6063 * Added backpointer to server's router into SilcServer context in
6064 silcd/server_internal.h.
6066 * Fixed silc_server_packet_broadcast to send correct broadcast
6069 * The channel key is now distributed to the local client as soon
6070 as it is received from the router (in router environment) so that
6071 no other packet may be sent for the channel until client has
6074 * silc_server_remove_channel_user now broadcasts the received
6075 Remove Channel User packet if it is not broadcast packet already.
6076 The router must broadcast to inform other routers about removed
6079 * Added users field into SilcPacketContext that is a reference count
6080 of the context. One can increase the reference count by calling
6081 silc_packet_context_dup which is now changed to just increase the
6082 reference count instead of duplicating the data. The reference
6083 count is decresed by calling silc_packet_context_free that will
6084 free the data after the reference count hits zero.
6086 For now on the packet context and everything allocated into it
6087 (including the raw packet from network) must be freed by calling
6088 the new silc_packet_context_free function. Added also new function
6089 silc_packet_context_alloc that must be used now to allocate the
6090 context. This also means that if a routine is asynchronous from
6091 silc_[client/server]_packet_parse_type the packet context must
6092 be duplicated by calling silc_packet_context_dup. Otherwise it
6093 gets free'd after silc_[client/server]_packet_parse_type returns.
6094 Also, one must remember that if packet is duplicated then its
6095 reference count must be decresed by calling the free function as
6096 many times as it was duplicated.
6098 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6099 from both client and server.
6101 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6103 * Made joining to a channel working in router environment.
6105 * Cleaned up JOIN command on server side and create function
6106 silc_server_command_join_channel internal routine to make the
6109 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Changed silc_command_pending list to SilcDList. Also, added
6112 `ident' field to SilcServerCommandPending structure to identify
6113 the reply and to call correct callback.
6115 Added silc_server_command_pending_check function to replace the
6116 corresnponding macro. The silc_command_pending list is not
6119 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6120 to set identifier to previously allocated Command Payload. It
6121 is used to set identifier for command when resending Command
6124 * Added silc_command_payload_encode_payload to encode Command
6125 Payload buffer from SilcCommandPayload structure.
6127 * Added silc_argument_payload_encode_payload to encode Argument
6128 payload buffer from SilcArgumentPayload structure.
6130 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6132 * Changed WHOIS command to support router connection on server side.
6133 The whois request is always sent to router unless the server is
6134 standalone server. After server has received the reply from the
6135 router will it send the reply to the client.
6137 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6138 broadcast received broadcast packet. The function is used only
6139 by router. The broadcast packet is always sent to the router's
6142 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6143 render given ID to printable string, for log files for example.
6145 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Made basic router to router connections working. At least they
6148 can now connect to each other but nothing really works the way
6149 they are supposed - yet.
6151 * Added new initiator token to RouterConnection configuration
6152 file in silcd/serverconfig.[ch]. It is used to tell whether we
6153 are the initiator to the remote router or whether we'll expect
6154 the other end to connect.
6156 * Moved registering of listener task to silc_server_init, hence
6157 the server starts listenning as soon as it is run, even if it
6158 does not have connections to other routers. Let's see how well
6161 * Changed default connection retry timeouts for more suitable in
6164 * Removed cipher and such arguments from silc_idlist_add_client
6165 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6166 Added new function silc_idlist_add_data to add the keys and stuff
6169 * Added SilcIDListData structure and added it to SilcClientEntry
6170 and SilcServerEntry as their first field in the structure. This
6171 way we can explicitly cast the ID entries to the SilcIDListData
6172 structure and get common data for the entries. In past, we had
6173 to first check what type of connection it is and then cast it to
6174 correct ID entry type. Now, we can directly cast the opaque
6175 pointer to the SilcIDListData (no matter what ID entry it actually
6176 is) and get the data needed.
6178 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6181 in some circumstances even if threre were timeout tasks, though not
6182 IO tasks, but tasks anyway. Now fixed.
6184 * Defined SilcServerConnection structure to hold connection specific
6185 stuff about directly connected servers and routers. The definition
6186 is currently in silcd/server_internal.h. I thought about having
6187 a bit more important role fro this struct but for now it is used
6188 only when connecting to other server (or router actually).
6190 * Added connecting retry support in server when connecting to
6191 router(s). The retry feature implement exponential backoff
6192 algorithm. Also, added SilcServerParams structure to hold default
6193 parameters for server. For now, it include these retry settings
6194 and are hard coded. After server is moded to be as Silc Server
6195 Library this structure will be more important.
6197 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Changed client librarys channel->clients table to SilcList and
6200 changed code accordingly.
6202 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Changed client's channel table to SilcList and changed code
6205 accordingly. Also changed SilcChannelClientEntry to include back-
6206 pointer to the channel so that client entry can use that structure
6207 as list as well and we have fast cross-reference to the channel.
6208 This change dramatically decreased the complexity of channel
6209 handling with client entry and vice versa (removed one extra
6210 loop when searching for channel entry from many functions).
6212 * Changed server->sim from table to SilcDList and changed code
6215 * NAMES command can now be used from user interface. It will show
6216 the user list on the channel, neatly.
6218 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6219 Code now saves realname of the user if it becomes available.
6221 * Renamed configure.in to configure.in.pre and made ./prepare
6222 script to automatically add correct version string to
6223 configure.in which it creates from configure.in.pre.
6225 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * NAMES command reply now shows users mode with the nickname when
6230 * Moved silc_client_ch[u]mode[_char] functions from
6231 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6232 place sucks, they are utility functions and should be in some
6235 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6237 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6240 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Added TRQ (efficient deque and list library) into lib/trq. This is
6245 a very good list library that is currently used in the SILC. Defined
6246 SilcList API over the library because I didn't like the API very
6247 much. See lib/trq/silclist.h for the API and examples of how to
6248 use the API. Fixed various places in the code to use the new
6249 SilcList API. The SilcList is meant for lists that has a structure
6250 already defined as a list. It is not suitable to add just some
6251 context to the list (in TRQ, the context is the list actually).
6253 So, I defined SilcDList that can be used for the purpose where
6254 predefined list structure does not exit. This can be used as
6255 such list. Now some context just can be added to the SilcDList.
6256 Currently this list is not used in the SILC just yet, though there
6257 are a lot places where this can replace dynamically allocated
6258 tables and I will fix these places, later, to use SilcDList.
6259 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6260 and use TRQ internally).
6262 Also fixed some annoying warning messages that the original TRQ
6263 code generated. Also minor changes to TRQ's Makefile.in.
6265 * Added support for querying by Client ID to both WHOIS and
6266 IDENTIFY commands into server, as required by the protocol.
6268 * Removed method function pointers from SilcBuffer structure. They
6269 weren't used to anything and just increased the context size for
6270 no good reason. This change also made silc_buffer_alloc and
6271 silc_buffer_free functions inline functions.
6273 * Disabled command flooding detection support until it's fixed so
6274 that it accepts commands in but does not execute them more than once
6277 * Added silc_net_localhost(), to return local hostname, into
6278 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6279 that must be initialized before calling silc_client_init.
6281 * Added new function: silc_server_send_notify_on_channels to send
6282 notify messages to all channels client has joined. It is assured
6283 that the message is sent only once per client.
6285 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6286 lib/silcutil/silcutil.[ch] as silc_format function. The new
6287 function is generic and is used by server as well, not only by
6288 the logging routines.
6290 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6291 the provided version string was not acceptable. Added new function:
6292 silc_ske_check_version into lib/silcske/silcske.h. The function
6293 must be implemented by the application (client or server) and it
6294 does not reside in the SKE library. The function checks the version
6295 string remote end sent.
6297 * Added back pointers (to opaque context and to SilcSocketConnection)
6298 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6300 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6301 duplicate packet context structure.
6303 * Changed `notify' client operation to send same arguments as client
6304 receives from server except for ID's. ID's are mapped to correct
6305 ID entry and that is returned. Also, if channel entry is not sent
6306 by server but the notify is for channel the channel entry is sent
6307 to application (otherwise application doesn't know that it is for
6308 channel (library gets it from packet's Destination ID)).
6310 * Added silc_client_remove_from_channels into client library to
6311 remove a client from all channels it has joined to. Used when
6312 received SIGNOFF notify from server. Added also new function
6313 silc_client_replace_from_channels to replace old ID entry with
6314 new ID entry on all channels. Used when received NICK_CHANGE
6317 * Fixed ID Cache list handling in silc_idlist_get_client in
6318 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6319 to get (or query) client by ID.
6321 * Updated TODO list.
6323 * Added connection authentication status message defined by the
6324 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6325 support for these into the code in client and server side.
6327 * Added generic function silc_client_send_command to send any command
6328 with variable argument list. Application should use this function
6329 to send commands if the command functions provided by the library
6330 does not suite for the application's user interface needs.
6332 * Added new `failure' client operation. Application is notified about
6333 received failure packet if client is executing a protocol. In this
6334 case the protocol's execution has failed.
6336 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6337 is required by the protocol.
6339 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6340 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6343 * Added status flag to SilcSKE object to indicate realtime status
6344 of the SKE protocol.
6346 * Application receives now exactly same command reply arguments as
6347 the library receives from server. However, if ID is received the
6348 corresponding ID entry is returned to the application (eg. Client
6349 ID is mapped to correct SilcClientEntry entry and that is returned).
6350 Changed command_reply client operation due to this change.
6352 * Changed all ID's in commands and in command replys as ID Payloads.
6353 Change affected both client and server side codes.
6355 All ID's sent in SILC network (with execption of ID's in SILC
6356 Packet header) are sent in ID Payload to support variable length
6359 * Server now notifies nick changes and notifies all clients on
6360 the channels about the new nickname (about the new Client ID,
6363 * Implemented CMODE command to change channel modes. Supports all
6364 channel modes defined by the protocol specs except ban and invite
6365 lists. (Also, private channel key mode is supported but support for
6366 setting private channel key in client is missing, thus, this mode
6367 has no effect on client side (except that server requires that the
6368 client uses private channel key and normal channel traffic does not
6371 Also, invite mode works per se, but INVITE command does not work
6372 yet correctly, so you can set channel as invite only channel but
6373 inviting clients to the channel does not work (it is yet to be
6374 thought what's the best way to do it).
6376 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6377 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6378 Implemented CUMODE command to change user's mode on the channel.
6379 Supports all modes defined by the protocol specs.
6381 * Added NAMES command reply to return users modes on the channel.
6383 * Removed unnecessary and slow ciphers from lib/silccrypt.
6385 * Set SO_KEEPALIVE option to connection sockets by default.
6387 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6389 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6390 redefined the Notify Payload into protocol specs.
6392 * Added silc_id_payload_parse_id to get ID directly from raw
6395 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6397 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6398 accept searching by Client ID as well.
6400 * Added support for LEAVE and SIGNOFF notify types in client library.
6402 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6403 to parse ID Payload from raw data.
6405 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6407 * Added flags parameter into silc_ske_assemble_security_properties
6408 function in lib/silcske/silcske.[ch].
6410 * Changed notify client operation to fit better for notify messages
6411 sent by server. The notify payload received from server is now
6412 passed to the application (after parsing it to SilcNotifyPayload).
6413 It is application's responsibility to retrieve the arguments
6414 from the payload and show the message the way it wants. The message
6415 sent by server is implementation specific.
6417 * Changed public keys to comply with the protocol specification.
6418 Old public keys are not supported anymore and are not compatible.
6420 * Removed nickname from Channel Payload as the latest draft removed
6421 it. The client must resolve the nickname from the NAMES command
6422 reply received when it joined the channel.
6424 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6426 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Fixed some errors in protocol specification drafts.
6430 * Created lib/silccore/silcnotify.c to implement Notify Payload
6431 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6432 generic payloads described by protocol specifications. The file
6433 includes implementations for ID Payload and Argument Payload.
6435 * Changed Command Payload implementation to use the new Argument
6436 Payload. Changed command_xxxx_payload to command_payload_xxxx
6437 to comply with SILC coding conventions.
6439 * Added suppport for Argument Payload handling in Notify Payload
6440 implementation as protocol requires it. Added the new support
6441 into server and client lib as well.
6443 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6445 * Added support for multiple nicknames on same channel. [n] is
6446 added locally to the nickname if there are more than one same
6447 nicknames on the channel.
6449 * Server now sends all nicknames that matched WHOIS request.
6450 Client also shows the list received from server.
6452 * Added TOPIC command to client side. User can now set and show
6453 current topic on channel.
6455 * Added MOTD command to client and server. Also, server sends the
6456 motd when client connects to the server.
6458 * Changed version strings to comply ISO 8601.
6460 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6462 * Fixed protocol error handling in client library. It should now
6463 cope even if the SKE fails for some reason.
6465 * Made new protocol specification drafts for submitting to IETF.
6467 * Implemented TOPIC command to server in silcd/command.c.
6469 * Added two new notify types into lib/silccore/silcnotify.h:
6470 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6471 notify nickname change and topic setting/change on a channel.
6473 * API change of command_reply operation in client library. The
6474 application gets now the status type received from server as well.
6476 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6480 * Cras fixed and optimized the packet handling even further and
6481 it should work now. Minor change to the prototype of function
6482 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6484 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6486 * Added new function into lib/silcutil/silcschedule.[ch]:
6487 silc_schedule_with_fd to select() a specified fd. The function
6488 returns after timeout expires or data arrives or goes. The
6489 function is used by packet routines to wait that all data is
6490 received from network.
6492 * Fixed data reading from network in lib/silccore/silcpacket.c.
6493 The code now assures that all data is read from the fd and then
6494 continues packet processing. This was a bug fix since the code
6495 used to drop some data in some circumstances.
6497 * Added new function into lib/silcclient/client.[ch]:
6498 silc_client_start_key_exchange to start key exchange after
6499 connection has been established to server. The code internally
6500 now uses this funtion but its main purpose was to provide it
6501 for applications that perform their own connecting. After
6502 application has created a connection it merely calls this
6503 function to start the key exchange between client and server.
6504 The library takes care of everything else after that.
6506 Updated also lib/silcclient/README to explain the usage of
6509 * Do not send to application information that connection has
6510 been established. Application gets notified it by connect
6513 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6515 * Applied cras's patch to add silc_schedule_one function. The
6516 function runs scheduler once and returns.
6518 * Fixed the scheduler after cras messed it up. The timeout
6519 handling works now as it's supposed to work.
6521 * Added into lib/silccore/ silcnotify.h to include notify
6522 message types support. Changed silc_server_send_notify*
6523 functions, in server.[ch], to support those new notify types.
6524 Added the support for the notify types into client library,
6525 as well. Added new notify client operation into ops.h in
6528 * Changed silc_server_packet_send_to_channel to send normal
6529 packets instead of just channel message packets. The function
6530 is now used to send the notify packets to channels. It is not
6531 used to send channel message packets anymore, as server never
6534 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6535 va_arg()s as it seems to require it nowadays. I guess, if SILC
6536 is compiled with older va_arg() the new code should work anyway.
6538 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6540 * Splitted core library. Core library (lib/silccore) includes
6541 now only SILC protocol specific core (and common) components.
6542 Created new utility library (lib/silcutil) that includes more
6543 generic purpose stuff. The stuff for util library was taken
6544 from the old core library. This was minor and easy split.
6546 * Created SILC Client Library (lib/silcclient) that includes
6547 implementation of the SILC client without user interface. This
6548 was major move from silc/ directory. The code has been changed
6549 so that it is transparent towards the user interface. The
6550 silc/ directory includes now the same user interface as before
6551 and it uses the new client library. Read lib/silcclient/README.
6552 Basicly, the client library performs everything else related
6553 to SILC except user interface handling. Also, configuration
6554 files are considered to be part of user interface and library
6555 does not handle them.
6557 This change also changed a lot of structures, function naming etc.
6558 Most important change was that SilcClientWindow object was
6559 renamed to SilcClientConnection in the client library. Created
6560 also new file lib/silcclient/ops.h. Also added new files
6561 silc/local_command.[ch] and silc/client_ops.[ch].
6563 All these changes were made to make it easier for user interface
6564 designers to create what ever user interface for the SILC client
6567 It is also expected that the server will be moved to lib
6568 directory as well and SILC Server Library will be created;
6569 sometimes in the future.
6571 * Removed Local commands from lib/silccore/silccommand.h as
6572 they are application specific and new client library does not
6573 handle any of those anymore.
6575 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6576 old client implementation in silc/.
6578 * Added support for callback functions in SILC_LOG_* macros.
6579 Application can now set its own callbacks that will be called
6580 instead of using the default functions that will always print
6581 the debug messages to stderr (or stdout). Also, debugging can
6582 now be disabled by setting silc_debug to FALSE and re-enabled by
6583 setting it to TRUE. Note, that logging will still work even
6584 if debugging is disabled.
6586 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6587 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6588 silc_log_reset_debug_callbacks.
6590 * To enable debugging in silc client one must give now -d
6591 option on command line.
6593 * Changed silc_schedule_init to automatically allocate task queues
6594 if they are not allocated before calling it.
6596 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Added GMP 3.1 into math library.
6600 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6603 a channel in SILC network. The packet is used by servers and
6604 routers to notify other routers that user has left a channel.
6605 This little feature was missing until now. Added the feature
6606 to protocol specification as well.
6608 Added functions: silc_server_send_remove_channel_user and
6609 silc_server_remove_channel_user into server.[ch].
6611 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6612 lib/silccore/silcpacket.h. However, they are not implemented
6615 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Fixed joining to a channel and sending channel messages
6618 between server and router. The channel message sending should
6619 now work inside a cell.
6621 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6623 * Fixed the private message sending between server and router.
6624 The private message sending should now work inside a cell.
6626 * Added silc_server_replace_id into server.[ch] to replace
6627 existing ID in the SILC network.
6629 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6630 and silc_idlist_replace_server_id into idlist.[ch] in server.
6632 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Fixed the server to server connections. Server can again now
6635 connect to router. Router to router connections probably does
6638 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6640 * Added dynamic protocol registering support. Now protocols can
6641 registered and unregistered on the fly. Patch by cras.
6643 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6645 * Added lib/contrib directory to hold routines that some platforms
6646 don't have but are needed by SILC.
6648 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6649 into lin/contrib to provide getopt() and getopt_long() for
6650 those who don't have it.
6652 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6654 * Added AWAY command to client. When away message is set and
6655 client receives a private message packet the client automatically
6656 replies to the sender with the away message.
6658 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6659 bug seemed to be the cause of recent problems when compiling
6662 * Added version detection support to SKE protocol specification
6663 and added the new changes to the SKE implementation as well.
6664 There were other minor changes in the SKE protocol as well.
6666 Many changes in lib/silcske/silcske.[ch] and in
6667 lib/silcske/payload.[ch].
6669 * Added ^U functionality, clear input line. Patch from cras.
6671 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6673 * Mainly small bugfixes on core library. Fixed some debugging
6674 logging and buffer overflow in silclog.c.
6676 * Updated config.sub and config.guess on the distribution tree.
6678 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Added command lagging support in server. Client may execute
6681 commands now only once in two seconds.
6683 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6685 * Optimized packet reception. MAC computation and checking is now
6686 also more optimized. A lot previously duplicated code is now
6687 used as generic by both client and server.
6689 * Fixed key pair generation in clientutil.c
6691 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6693 * Added into lib/silccore/silcbufutil.[ch] new function;
6694 silc_buffer_realloc.
6696 * Moved generic packet sending/encryption functions to
6697 lib/silccore/silcpacket.[ch] from client and server. Some
6698 rewriting of the functions.
6700 * Moved all generic packet reception/decryption functions to
6701 lib/silccore/silcpacket.[ch] from client and server. The
6702 packet processing is now much cleaner in both client and server.
6703 These were major changes in both client and server.
6705 * Created many common functions in server to do packet sending.
6706 Previously code were duplicated a lot, this has been removed
6709 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * Rewrote major parts of the ID cache system. Don't know
6712 whether it is better now or not but at least the API is more
6715 * Major rewrite on ID cache stuff on client because of the ID
6716 cache API changes. Added idlist.c to client.
6718 * Also major rewrite on ID cache stuff on server as well.
6719 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6720 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6721 in hand, instead they are all put into the ID cache system now.
6722 All server_idlist_* routines uses ID cache now instead of
6723 traversing its own lists (those lists does not exist anymore).
6724 SilcIDList though still exists. Also, SilcXXXEntry's are
6727 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6729 * Finally made the SKE implementation compliant to the protocol
6730 specification. All mp integers are now binary encoded as
6731 opposed being HEX encoded.
6733 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6736 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6737 functions: silc_[encode/decode]_pem. Also added function
6738 silc_encode_pem_file to PEM encode with newlines ('\n') for
6741 * SILC public keys are now encoded either PEM or binary. Same
6742 option is for private keys as well. By default private keys
6743 are binary encoded and public keys PEM encoded. Silly HEX
6744 encoding were removed.
6746 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6747 function to create fingerprints.
6749 * Fixed a bug in SHA1; does not change the original data anymore.
6751 * Partly implemented INFO command on client and server side.
6752 Fixed CLEAR command. Changes to SERVER command; show current
6753 server(s) when giving command without arguments. Added
6754 VERSION command to client.
6756 * Added check to server that unregistered connections cannot
6757 execute commands (unless it is specificly allowed).
6759 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6761 * Fixed screen refresh.
6763 * Fixed channel joining bug from client. On some circumstances
6764 client tried to join to a channel it had already joined.
6766 * Added public key verification process into client's protocol.c.
6767 The client now verifies the public key from user and saves
6768 it into ~./silc/serverkeys/ directory.
6770 Added into: clientutil.[ch]: silc_client_verify_server_key.
6772 * Changed SKE protocol's silc_ske_initiator_finish function
6773 to accept callback function that verifies the received public
6774 key. Removed old silc_ske_verify_public_key function.
6776 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6778 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6779 silc_pkcs_private_key[_data]_set.
6781 * Made the password and public authentication more cleaner in
6782 server's protocol.c.
6784 * Removed historic and obsolete protocol `channel_auth' from
6785 both client and server.
6787 * Removed wrong way of sending command status messages from
6788 server to client in server's command.c. The old way violated
6789 protocol specification.
6791 Changes to silccore/silccommand.[ch]: removed
6792 silc_command_encode_status_payload -> not needed anymore,
6793 changed silc_command_encode_payload_va to accept extra
6794 argument on variable argument list. The argument type must
6795 now be provided to the function. Also, added new function:
6796 silc_command_encode_reply_payload_va which is same as
6797 normal command_encode_payload_va except command status type
6798 is provided as extra argument.
6800 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Added ~./silc directory handling. The directory includes the
6803 public and private keys for the client.
6805 Added silc_client_check_silc_dir, silc_client_create_identifier
6806 and silc_client_load_keys.
6808 * Implemented SILC protocol compliant public key. Added public
6809 and private key saving to and loading from files.
6811 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6812 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6813 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6814 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6815 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6817 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6818 silc_pkcs_load_[public/private]_key.
6820 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6822 * Added silc_server_get_route (route.[ch]) to get connection
6823 data for the fastest route for given ID.
6825 * Implemented INVITE command on client and server. The command
6826 were re-defined in the SILC Protocol Specification and the
6827 implementation now complies with the specification.
6829 * Implemented PING command on client and server.
6831 * Implemented NAMES command on client and server. The server side
6832 supports currently only normal server not router server yet.
6833 Some changes to NAMES definition in SILC protocol specification.
6835 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6837 * Implemented LEAVE command on client and server.
6839 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6840 again. This change was made to the protocol as well. Server
6841 should not violate the protocol specification anymore.
6843 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6845 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6846 was tested. SOCKS4 was not but should work anyway.
