1 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
5 * Fixed the NICK command to always give the unformatted
6 nickname to the one giving the NICK command. If unformatted
7 nickname is cached already it will be formatted and the
8 local entry will always get the unformatted nickname.
9 Affected file lib/silcclient/idlist.c.
11 * Fixed some double frees from client library commands.
12 Affected file is lib/silcclient/command.c.
14 * Fixed CUMODE command in server to assure that no one can
15 change founder's mode than the founder itself, there was a
16 little bug. Affected file silcd/command.c.
18 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
20 * Removed the SilcClientCommandDestructor from the client
21 libary, it is not needed anymore. Affected files are
22 lib/silcclient/silcapi.h, command[_reply].[ch],
23 client_notify, idlist.c.
25 * Fixed GETKEY command to first resolve client, and then
26 resolve the server only if the client was not found, instead
27 of resolving both at the same time. Affected file is
28 lib/silcclient/command.c.
30 * Added silc_client_start_key_exchange_cb and lookup the
31 remote hostname and IP address before starting the key
32 exchange with server. The affected file is
33 lib/silcclient/client.c.
35 * The server's public key is now saved using the IP address
36 of the server and not the servername for the filename.
37 The hostname public key filename is checked as an fall back
38 method if the IP address based filename is not found.
40 Fixed the GETKEY command to save the fetched server key
43 Print the remote server's hostname now when new key is
44 received during connection process. Affected file is
45 irssi/src/silc/core/client_ops.c.
47 * Return always our own public key to the client if it asks
48 for it with GETKEY command. Affected file silcd/command.c.
50 * Removed the use_auto_addr variable from default config
51 file since it was in wrong section. Affected file is
54 * Fixed TOPIC_CHANGE notification to not route it when it
55 was sent using silc_server_send_notify_to_channel function.
56 Affected file silcd/command.c.
58 * Fixed silc_server_send_notify_kicked to send the kicker's
59 Client ID also, it was missing. Affected files are
60 silcd/command.c, silcd/packet_send.[ch].
62 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
64 * Do not save client history information in SERVER_SIGNOFF.
65 Fixes the bug in normal server that it does not detect
66 the client becoming valid after the server becomes back
67 online. Affected file silcd/server_util.c.
69 * Added `sock_error' field into the SilcSocketConnection
70 context. When error occurs during socket operation (read
71 or write) the error is saved. Added also new function
72 silc_socket_get_error to return human readable socket error
73 message. Affected files are lib/silcutil/silcsockconn.[ch],
74 lib/silcutil/unix/silcunixsockconn.c, and
75 lib/silcutil/win32/silcwin32sockconn.c.
77 * The server now prints the socket error message in the
78 signoff for client. Affected file silcd/server.c.
80 * Fixed the `created' channel information sending from router
81 to server in JOIN command. Checks now whether the channel
82 really was created or not and set it according that.
84 Fixed the JOIN command to use the client entry's current
85 ID during the joining procedure instead of the one it sent
86 in the command (it is checked though), since it can change
87 between the packet processing and command processing, and
88 would just case unnecessary pain in the client end. Affected
91 * Fixed a channel key payload sending to use correct channel
92 ID when the server was forced to change the channel's ID by
93 router. Router sent the key payload with the old Channel ID.
94 Affected file silcd/packet_receive.c.
96 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
98 * Call silc_server_save_channel_key only if the key payload
99 was provided in the JOIN command's command reply. Affected
100 file silcd/command_reply.c.
102 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
104 * Fixed silc_mp_sizeinbase to return the value correctly with
105 MPI. Affected file lib/silcmath/mp_mpi.c.
107 * Fixed the stop_server signal to correctly stop the scheduler
108 and gracefully stop the server when SIGTERM or SIGINT signals
109 are received. Affected file silcd/silcd.c.
111 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
113 * Simple handling of TERM and HUP signals. Also added some log
114 flushing call around. Affected file is
117 * Fixed small bugs in silclog.c. Now buffering output will take
118 effect after 10 seconds since startup: This will ensure that
119 no important startup messages are lost. Also output redirection
120 will preserve original format ([Date] [Type] message).
121 Affected file is lib/silcutil/silclog.c.
123 * Added two options to the config file, in the logging section:
124 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
125 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
127 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
129 * Do not print the warning about log files not being initialized
130 more than once to avoid excess logging. Affected file is
131 lib/silcutil/silclog.c.
133 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
134 the SIM copying in make install in Makefile.am.pre.
136 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
138 * Rewritten silclog APIs. Globally interesting changes follows:
139 silc_log_set_files() changed to silc_log_set_file().
140 silc_log_set_callbacks() changed to silc_log_set_callback().
141 ROBOdoc documented silclog header file.
142 SilcLogCb now returns bool to wether inihibit the default
143 handler or not (to keep the old behaviour return always TRUE).
144 The new APIs should also fix the problem of the
145 silcd_error.log file that was written in the current directory.
148 Log files streams will remain opened after silc_log_set_file()
149 call, means less CPU usage notably on high traffic servers.
150 File streams are now full buffered, and flushed to the disk
151 every 5 minutes, lesses HD activity and CPU usage.
152 Messages can be redirected, allowing admins to configure
153 one single logfile for all server messages.
154 the silc_log_quick global variable to activate fast-logging.
155 Affected files lib/silcutil/silclog.[ch]
157 * Changed some code to conform new silclog APIs. Affected
158 files are doc/example_silcd.conf.in, silcd/server.c
159 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
162 * Fixed a memory leak that could occur in some situations.
163 Affected file silcd/serverconfig.c.
165 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
167 * Added the silc_client_del_client to remove the client from
168 all channels as well. Affected file lib/silcclient/idlist.c.
170 * Fixed the client library to correctly remove the client
171 from all channels when the client entry is being destroyed.
172 Affected file lib/silcclient/client_notify.c, command.c.
174 * Added auto-nicking support to the client library. If the
175 applicatio now sets client->nickname it will be sent to the
176 server after connecting by the library. This way for example
177 SILCNICK (or IRCNICK) environment variables will have effect
178 and always change the nickname automatically to whatever
179 it is wanted. Affected file lib/silcclient/client.[ch].
181 * Renamed silc_server_command_bad_chars to the
182 silc_server_name_bad_chars and moved it to the
183 silcd/server_util.[ch]. Added also new function
184 silc_server_name_modify_bad to return nickname that
185 includes bad characters as new nickname without those
186 bad characters. This check and modify is now used in
187 silc_server_new_client when the username is initially set
188 as nickname, so it must be checked to be valid nickname.
189 Affected file silcd/packet_receive.c.
191 * The nickname length is now taken from the packet for real
192 and not trusted to strlen() since it clearly can return
193 wrong length for nickname including bad characters. This
194 also applies to channel names. Affected file silcd/command.c.
196 * Removed the lib/silcsilm/modules directory. Modules are now
197 compiled into the lib/silcsim. Fixed the copying of the
198 modules to follow symbolic links in Makefile.am.pre.
200 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
202 * Fixed silc_string_regexify list creation. Fixes bugs with
203 BAN and INVITE commands in server. The affected file is
204 lib/silcutil/unix/silcunixutil.c.
206 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
208 * Removed the command destructor entirely from the server's
209 command and command reply routines. It is not needed, and
210 its usage was buggy and caused crashes. Affected files are
211 silcd/command[_reply].[ch].
213 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
215 * Cancel protocol and NULL sock->protocol if timeout
216 occurred during protocol. Affected file silcd/server.c.
218 * Cancel protocol timeouts always before calling the final
219 callback, to assure that after final callback is called
220 no other state will be called for the protocol anymore.
221 Affected file silcd/protocol.c.
223 * Print error log if incoming connection configuration could
224 not be found. Affected file silcd/server.c.
226 * Fixed JOIN command to correctly save the founder mode
227 to the client on normal SILC server, when the channel
228 was created by the router. Affected file silcd/command.c.
230 * Fixed LIST command (hopefully) to send correct reply
231 packets. Affected file silcd/command.c.
233 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
235 * The silc_packet_receive_process now returns FALSE if the
236 read data was invalid packet, and TRUE if it was ok.
238 The server now checks that if unauthenticated connection
239 sends data and its processing fails the server will close
240 the connection since it could be a malicious flooder.
242 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
244 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
246 * Make sure the warning about error opening a log file is
247 printed only once and not everytime it fails (produces
248 too much useless log). Affected file lib/silcutil/silclog.c.
250 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
252 * Made the silc_server_daemonise() function more readable.
253 Affected file silcd/server.c.
255 * Pid file is now optional, the user may comment it out from
256 the config file. Removed define SILC_SERVER_PID_FILE, we
257 don't need a default any longer. Affected file
258 configure.in.pre, lib/Makefile.am.pre.
260 * Make some use of the pid file. The server now dies at startup
261 if it detects a valid pid file on his path. The server would
262 die anyway in this circumstance, because of the bind() failure.
263 Affected file silcd/silcd.c.
265 * No longer compiling lib/dotconf.
267 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
269 * Fixed JOIN command parsing not to crash. Affected file
270 lib/silcclient/command.c.
272 * Fied the NICK_CHANGE notify to add the new client entry
273 even it is resolved. This removes an <[unknown]> nick
274 thingy bug in the client. Affected file is
275 lib/silcclient/client_notify.c.
277 * Do not try to allocate 0 bytes (efence does not like it)
278 in lib/silccore/silccomand.c when encoding payload.
280 * Do not take IRCNICK as nickname in Irssi SILC client since
281 it is not possible to set nickname before hand connecting
282 the server (TODO has an entry about adding auto-nicking
285 * Changed the silc_server_command_pending to check whether
286 there already exists an pending entry with the specified
287 command, command identifier and pending callback. This is
288 to fix IDENTIFY and WHOIS related crashes that may register
289 multiple pending commands with same identifier. Affected
290 file silcd/command.c.
292 * Fixed the server to reconnect to the router even if it
293 was already reconnecting and EOF was received. This to
294 fix a possibility that the server wouldn't ever try to
295 auto-reconnect to the router. Affected file silcd/server.c.
297 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
299 * Fixed the server's password authentication to use the
300 length of the locally saved password, and not the one
301 sent in the packet. Affected file silcd/protocol.c.
303 * Fixed same password authentication problem in the
304 Authentication Payload handling routines in
305 lib/silccore/silcauth.c.
307 * Yet another password authentication problem fixed with
308 channel password handling in silcd/command.c.
310 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
312 * If first character of string in silc_parse_userfqdn is '@'
313 then do not parse it. Affected file is
314 lib/silcutil/silcutil.c.
316 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
318 * Fixed minor bug in IDENTIFY command reply sending, which
319 caused various weird problems during JOIN when it was
320 resolving names for users. Affected file silcd/command.c.
322 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
324 * Fixed the IDENTIFY command reply sending to chech better valid
325 clients. It was possible to send incomplete list of replies.
326 Affected file silcd/command.c.
328 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
330 * Added silc_client_command[s]_[un]register functions now to
331 dynamically register the commands in client library. Removed
332 the static table of commands. This allows the client library
333 to call commands without causing the application to know about
334 what commands library has called.
336 Removed the INFO command reply kludge to detect when the command
337 was called by library. Now library use its own command reply
338 function for INFO command.
340 Added function silc_client_command_call to call a command.
341 Application can use it to call command, not access the structure
344 Now all commands that are sent by the client library (not
345 explicitly sent by application) use own command reply functions.
347 Affected files around lib/silcclient/ and in
348 irssi/src/silc/core/.
350 * Fixed the WHOIS command reply sending to chech better valid
351 clients. It was possible to send incomplete list of replies.
353 Fixed the WHOIS and IDENTIFY to send the request to router
354 if normal server did not do it and did not find any results.
356 Affected file silcd/command.c.
358 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
360 * Moved the internal data from SilcClient context into its
361 own file, not accesible to application. Affected files
362 lib/silcclient/client.h and lib/silcclient/client_internal.h,
363 and other files in client library.
365 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
367 * Added doc/examples installation target in Makefile.am.pre.
370 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
372 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
373 commands the found client entry will be removed from the
374 cache, after notifying application about the error. Affected
375 file lib/silcclient/command_reply.c.
377 * Changed the /MSG to check for exact nickname user gave, and
378 not let `nick' match `nick@host' if it is only one found. Now,
379 user must type the exact nickname (like nick@host2) even if
380 there are no more than one same nicks found. This is to avoid
381 a possibility of sending nickname to wrong nickname since
382 `nick' could match `nick@host'. Affected file is
383 irssi/src/core/silc-servers.c.
385 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
387 * Do not print "you are now server operator" or similar when
388 giving /away command. Affected files are
389 irssi/src/silc/core/client_ops.c, silc-servers.h.
391 * Made the silc_server_command_pending_error_check to send
392 the same command reply payload it received back to the
393 original sender of the command. This way all arguments
394 that was received by the server will be received by the
395 client too. Affected file silcd/command.c.
397 * Added the silc_idcache_add to return the created cache entry
398 to a pointer. Affected file lib/silccore/silcidcache.[ch].
400 * Add global clients to expire if they are not on any channel.
401 This is because normal server will never know if they signoff
402 if they are not on any channel. The cache expiry will take
403 case of these entries. This is done by normal servers only.
404 The affected files are silcd/command_reply.c,
405 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
407 * If server receives invalid ID notification for WHOIS or
408 IDENTIFY and the ID exists in the lists, it is removed.
409 Affected file silcd/command_reply.c.
411 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
412 in client then client entry that it matches is searched and
413 the nickname is printed on the screen for user. Affected
414 file irssi/src/silc/core/client_ops.c.
416 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
418 * Use cache entry expire time in the LIST command reply to
419 purge old entries from the cache after the LIST command
420 reply has been received. This way we don't have non-existent
421 entries in the cache for too long. Affected file is
422 silcd/command_reply.c.
424 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
426 * If we are normal server, and we've not resolved client info
427 in WHOIS or IDENTIFY from router, and it is global client,
428 we'll check whether it is on some channel. If it is not
429 then we cannot be sure about its validity and will resolve it
430 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
431 file silcd/command.c.
433 * Search channel by name (if possible) rather than by ID
434 in IDENTIFY command's command reply. Affected file is
435 silcd/command_reply.c.
437 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
439 * Distribute to the channel passphrase in CMODE_CHANGE notify.
440 Updated specs and implemented it. Affected file silcd/command.c,
441 silcd/packet_send.c and silcd/packet_receive.c.
443 * Implemented the <founder auth> payload handling in the JOIN
444 command. If provided all conditions for channel joining
445 except requirement to provide correct passphrase can be
446 overrided by the channel founder. Updated the protocol specs.
447 Affected file silcd/command.c.
449 Added support for founder auth in JOIN command in client
450 library. Fixed the parsing of the JOIN command now to support
451 all options as they should be. The affected file is
452 lib/silcclient/command.c.
454 * Optimized the WHOIS and IDENTIFY commands to send the request
455 to router only if it includes nicknames or other names. If
456 they include only IDs then check the local cache first before
457 routing. Affected file is silcd/command.c.
459 * Added channels topic announcements. Affected file is
460 silcd/packet_receive.c and silcd/server.c.
462 * Fixed the silc_server_send_notify_topic_set to really destine
463 the packet to channel. Affected file silcd/packet_send.c.
465 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
466 library. Affected file lib/silcclient/client_notify.c.
468 * Added UMODE announcements. Affected file silcd/server.c.
470 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
472 * Memory leak fixes in:
474 lib/silcutil/silcsockconn.c
475 lib/silcske/silcske.c
478 lib/silccrypt/silcpkcs.c
479 lib/silccore/silccommand.c
480 lib/silccore/silcidcache.c
485 * ROBOdoc documented the lib/silcske/groups.h file and a
486 bit changed the interface for better.
488 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
490 * Update the client entry context in the ID cache after
491 nick change. Affected file lib/silcclient/command.c.
492 Fixes the CUMODE command when regaining founder privileges,
493 and a little WHOIS problem.
495 * Fixed silc_net_gethostbyname to correctly call the
496 inet_ntop. Affected file lib/silcutil/silcnet.c.
498 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
500 * Added IPv6 support checking to the configure.in.pre, added
501 also --enable-ipv6 option to override the check. Affected
502 file configure.in.pre.
504 * The silc_thread_create now calls the start function
505 directly if threads support is not compiled in. Removes
506 ugly #ifdef's from generic code. Affected files are
507 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
509 * Added silc_net_gethostby[name/addr]_async to asynchronously
510 resolve. Affected files are lib/silcutil/silcnet.[ch].
512 * Added support for rendering IPv6 based server, client and
513 channel IDs. Affected file lib/silcutil/silcutil.c.
515 * Added support for creating IPv6 based server IDs. Affected
516 file is silcd/serverid.c.
518 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
520 * Added silc_net_gethostby[addr/name] into the
521 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
522 routines. Added silc_net_is_ip[4/6]. Affected file is
523 lib/silcutil/unix/silcunixnet.c. All routines that take
524 address as argument now supports both IPv4 and IPv6 addresses.
526 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
528 * Fixed LIST command reply sending in server. Affected file
531 * Server now sends the kicker's client ID in the KICK notify
532 to the kicked client. Affected file silcd/command.c.
534 * The client library now parses the kickers client ID and
535 UI displays it. Affected files lib/silcclient/client_notify.c
536 and irssi/src/silc/core/silc-channels.c, module-formats.c.
538 * Made all payload parsing function prototypes consistent.
539 They all take now const unsigned char * and uint32 pair as
540 the payload data instead of SilcBuffer. Changes all around
541 the source tree. Other unsigned char* -> const unsigned char*
542 changes around the tree as well.
544 * Optimized SFTP client and server packet sending not to
545 allocate new buffer for each packet but to recycle the
546 first allocated buffer. Affected files are
547 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
549 * Optimized the SFTP client to use SilcList instead of
550 SilcDList for requests, because it is faster. Affected file
551 is lib/silcsftp/sftp_client.c.
553 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
554 into lib/silccore/silcid.[ch].
556 Renamed silcpayload.[ch] into silcargument.[ch].
558 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
560 * If client entry is deleted with active key agreement
561 session, abort the session.
563 The silc_client_abort_key_agreement now calls the completion
564 callback with new SILC_KEY_AGREEMENT_ABORTED status.
566 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
569 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
571 * Don't use __restrict in older GCC's. Affected file is
572 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
574 * silc_net_localhost now attempts to reverse lookup the
575 IP/hostname. Affected file lib/silcutil/silcnet.c.
577 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
578 command. It can be used to gain founder privileges at
579 the same time when joining the channel.
581 Defined that the SILC_NOTIFY_TYPE_KICKED send the
582 kicker's client ID as well. Updated protocol specs.
584 Defined that the server must send SILC_COMMAND_IDENTIFY
585 command reply with error status to client who sent
586 private message with invalid client ID.
588 Updated the protocol specification.
590 * Added silc_server_send_command_reply to send any
591 command reply. Affected file silcd/packet_send.[ch].
593 * Added silc_id_payload_encode_data to encode ID payload
594 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
596 * The server now send IDENTIFY command reply with error
597 status if client ID in private message is invalid. Affected
598 file silcd/packet_receive.c.
600 * Save the server key file with server's IP address in
601 the filename instead of hostname. The affected file is
602 irssi/src/silc/core/client_ops.c.
604 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
606 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
609 * Added libtool support for compiling shared objects in
610 lib/silcsim. Affected file configure.in.pre and
611 lib/silcsim/Makefile.am. Original patch by cras.
613 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
615 * Pid file configuration, and server's config file fixes
616 patch by toma. Updated CREDITS file.
618 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
620 * Fixed silc_client_channel_message to not try to decrypt
621 the message twice if it resolved the destination client
622 information. This could cause of dropping one channel
623 message. Affected file lib/silcclient/client_channel.c.
625 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
627 * Added silc_client_run_one into lib/silcclient/silcapi.h and
628 lib/silcclient/client.c. This function is used when the SILC
629 Client is run under some other scheduler, or event loop or
630 main loop. On GUI applications, for example this may be
631 desired to used to run the client under the GUI application's
632 main loop. Typically the GUI application would register an
633 idle task that calls this function multiple times in a second
634 to quickly process the SILC specific data.
636 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
638 * Fixed silc_server_drop() for dropping the supplementary
639 groups as well, this could cause a security hole on some
642 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
644 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

648 to run server on foreground. A patch by debolaz.
649 Affected files silcd/server.c, silcd/silcd.c.
651 * Fixed MOTD to return the MOTD file server name. Affected
652 file silcd/command.c.
654 * Added INFO command reply handling to the Irssi SILC Client.
655 Affected file irssi/src/silc/core/client_ops.c.
657 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
659 * Fixed the silc_idcache_list_* routines to really support
660 the dynamic list. Fixes a crash. Affected file is
661 lib/silccore/silcidcache.c.
663 * Fixed the LIST command reply to really call LIST command's
664 pending callbacks. Affected file silcd/command_reply.c.
666 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
668 * Update conn->local_entry->nickname after giving NICK
669 command. Affected file lib/silcclient/command.c.
671 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
673 * Added the [pid] option to the silcd configuration file
675 Affected files: serverconfig.[ch] and silcd.c
677 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
679 * Save fingerprint in WHOIS command reply in server.
680 Affected file silcd/command_reply.c.
682 * Fixed NICK commands pending callback registration.
683 Affected file lib/silcclient/command.c.
685 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
687 * Use ++server->cmd_ident when sending commands in server,
688 instead of random number. Affected file silcd/command.c.
690 * Fixed GETKEY command reply to call actually GETKEY pending
691 command callbacks. Affected file silcd/command_reply.c.
693 * A bit stricter check for nicknames. Check for same nickname
694 in NICK command also. Affected file silcd/command.c.
696 * Do not call INFO command everytime client ID changes, only
697 during first connecting. Affected file lib/silcclient/client.c.
699 * Set the new nickname only after successful command reply for
700 NICK command is returned by server. Affected file
701 lib/silcclient/command.c.
703 * Remove nicknames from nicklist during server_signoff notify.
704 Should fix /NAMES bit more. The affected file is
705 irssi/src/silc/core/silc-channels.c.
707 * Added `fingerprint' field to the SilcIDListData in the
708 silcd/idlist.h to hold the fingerprint of the client's
711 Send the fingerprint of the client's public key in WHOIS
714 Affected files silcd/command.c, and silcd/idlist.[ch].
716 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
717 create fingerprint from given data.
719 * Show the fingerprint of the client's public key in WHOIS.
720 Affected files irssi/src/module-formats.[ch] and
721 irssi/src/silc/core/client_ops.c.
723 * Format the multiple same nicknames also during JOIN and
724 NICK_CHANGE notifys. Affected file is
725 lib/silcclient/client_notify.c.
727 * Do not print error on screen for invalid private message
728 payload since it can come if someone is sending private
729 messages with wrong key. Affected file
730 lib/silccore/silcprivate.c.
732 * Fixed multiple concurrent /PING crash. Affected file
733 lib/silcclient/command.c.
735 * Changed the wrong ID encoding. All IP addresses must be
736 in MSB first order in encoded format. They were encoded
737 wrong and was in LSB format. Affected files are
738 silcd/serverid.c, lib/silcutil/silcutil.c.
740 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
742 * Call the `connect' client operation through the scheduler
743 in case of error. Affected file lib/silcclient/client.c.
745 * Call the `failure' client operation even if the error
746 occurred locally during a protocol. Affected file is
747 lib/silcclient/protocol.c.
749 * Added support of sending LIST command to router from normal
750 server. This way normal server can get list of all channels
751 in the network too. Fixed the channel list sending in the
752 server too. Affected files are silcd/command.c, and
753 silcd/command_reply.[ch].
755 * Added silc_server_update_channels_by_server and
756 silc_server_remove_channels_by_server. They are used during
757 disconnection of primary router and in backup router protocol.
758 Affected file silcd/server_util.[ch], silcd/server.c and
759 silcd/server_backup.c.
761 * Fixed channel adding to global list in IDENTIFY command
762 reply in server. Affected file silcd/command_reply.c.
764 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
766 * If the incoming packet type is REKEY or REKEY_DONE process
767 that packet always synchronously. Fixes yet another MAC
768 failed error on slow (dialup) connections. Affected file
769 lib/silcclient/client.c and silcd/server.c.
771 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
773 * Call check_version SKE callback for initiator too. Affected
774 file lib/silcske/silcske.c.
776 * Implemented fix for security hole found in the SKE that was
777 fixed in the specification few days back; the initiator's
778 public key is now added to the HASH value computation.
779 Added backwards support for the old way of doing it too, for
780 old clients and old servers. Affected file is
781 lib/silcske/silcske.c.
783 * Enabled mutual authentication by default in SKE. If initiator
784 is not providing mutual authentication the responder will
785 force it. This will provide the proof of posession of the
786 private key for responder. The affected files are
787 lib/silcclient/protocol.c and silcd/protocol.c.
789 * Do not cache anymore the server's public key during SKE.
790 We do mutual authentication so the proof of posession of
791 private key is done, and if the server is authenticated in
792 conn auth protocol with public key we must have the public
793 key already. Affected file silcd/protocol.c.
795 * Added new global debug variable: silc_debug_hexdump. If
796 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
797 file lib/silcutil/silclog.[ch].
799 * Fixed compilation warning due to char * -> const char *.
800 Affected files lib/silcutil/silcnet.h, and
801 lib/silccore/silcauth.[ch].
803 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
805 * Fixed CMODE command when new channel key was created. If
806 the creation failed the old key was removed. Next time giving
807 same command would crash the server since the old key was
808 freed already. Affected file silcd/command.c.
810 * Fixed the silc_server_announce_get_channels to not crash
811 on reconnect. Affected file silcd/server.c.
813 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
815 * Added silc_log_set_debug_string function to set a regex
816 string to match for debug output. Only the function names,
817 or filenames matching the given debug string is actually
818 printed. This way it is possible to filter out those debug
819 strings that user is not interested in.
821 Fixed a bug in silc_string_regexify.
823 Affected files lib/silcutil/silclog.[ch], and
824 lib/silcutil/unix/silcunixutil.c.
826 * Changed the -d options in both server and Irssi SILC client
827 to take the debug string as argument. Affected files
828 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
830 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
832 * Added silc_hash_babbleprint to create a Bubble Babble
833 Encoded fingerprint. The encoding is developed by Antti
834 Huima (draft-huima-babble-01.txt), and it creates human
835 readable strings out of binary data. Affected file
836 lib/silccrypt/silchash.[ch].
838 * Print the babble print now in addition of fingerprint as well
839 in Irssi SILC client. Affected files are
840 irssi/src/fe-common/silc/module-formats.[ch],
841 irssi/src/fe-common/silc/core/client_ops.c.
843 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
845 * Fixed a security problem found in SKE. The initiator's
846 public key too is now added to the HASH hash value creation
847 which is signed by the responder to create the SIGN value.
848 This will prevent anyone in the middle to lie to the responder
849 about the initiator's public key. If this is done now, the
850 man in the middle will get caught. Updated the protocol
853 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
855 * Better installation directory handling. Configure module
856 paths and other paths automatically to example_silc* files
857 in doc/. A patch by toma.
859 * Fixed compiler warning from MPI library, and from SILC RNG.
862 * Added SILC_SERVER_PID_FILE to define the pid file for server.
863 It can be configured with ./configure. A patch by toma.
865 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
867 * Find correct make to use in prepare-clean. A patch by
868 toma. Affected file prepare-clean.
870 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
872 * Added irssi variables use_auto_addr, auto_bind_ip,
873 auto_bind_port and auto_public_ip.
875 * Changed the interface for silc_client_send_key_agreement
876 in lib/silcclient/silcapi.h
880 irssi/src/silc/core/silc-core.c
882 lib/silcclient/silcapi.h
883 irssi/src/silc/core/silc-channels.c
884 lib/silcclient/client_keyagr.c
887 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
889 * Added silc_pkcs_public_key_compare to compare two
890 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
892 * Check that the client who set the founder mode on the
893 channel is the same client that is giving the founder
894 mode to itself. It is done by comparing the saved public
895 key (it is saved even in the authentication is passphrase).
896 Affected file silcd/command.c.
898 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
900 * Do not process packet for disconnected socket connection.
901 Affected file lib/silccore/silcpacket.c.
903 * Process the DISCONNECT packet through scheduler in the
904 client library. Affected file lib/silcclient/client.c.
906 * Fixed the silc_client_packet_parse to not to increase
907 the packet sequence number if the conn->sock and the
908 current socket connection is not same. This can happen
909 for example during key agreement when the conn includes
910 multiple socket connections (listeners). Affected file
911 lib/silcclient/client.c.
913 * The sender of the file transfer request now provides also
914 the pointer (listener) for the key exchange protocol. If
915 the listener cannot be created then it sends empty key
916 agreement and lets the receiver provide the listener.
918 Added `local_ip' and `local_port' arguments to the
919 silc_client_file_send. If they are provided they are used,
920 if not then it will attempt to find local IP address, if
921 not found or bind fails then the remote client will provide
924 Affected files are lib/silcclient/client_ftp.c and
925 lib/silcclient/silcapi.h.
927 * Extended the FILE SEND command to support defining the
928 local IP and port for key exchange listener. They are
929 optional. Affected file irssi/src/silc/core/silc-servers.c.
931 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
933 * Defined to WHOIS command reply the sending of fingerprint
934 of the client's public key (if the proof of posession of the
935 corresponding private key is verified by the server).
936 Updated to the protocol specification.
938 * Added support of receiving the client's public key's
939 fingerprint in command reply in client library. Affected
940 file is lib/silcclient/command_reply.c, and
941 lib/silcclient/idlist.[ch].
943 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
945 * Do not send over 128 chars long nickname to the server
946 in NICK command. Affected file lib/silcclient/command.c.
948 * Do not send over 256 chars long channel names to the server
949 in JOIN command. Affected file lib/silcclient/command.c.
951 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
953 * Assure that silc_server_close_connection cannot be called
954 twice for same socket context. Affected file is
957 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
959 * Send error message to application if opening file for
960 writing during file transfer fails. Affected file is
961 lib/silcclient/client_ftp.c.
963 Remove all file transfer sessions for a client that we're
964 removing from ID cache.
966 Affected file is lib/silcclient/client_ftp.c.
968 * Fixed silc_net_addr2bin to return correct address. Affected
969 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
971 * Fixed file transfer session removing on signoff notify.
972 Affected file irssi/src/silc/core/silc-servers.c.
974 * Added the SilcClientFileError to be returned in the monitor
975 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
976 Affected file lib/silcclient/silcapi.h.
978 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
980 * Fixed a crash in silc_client_ftp_free_sessions and
981 silc_client_ftp_session_free_client. Affected file
982 lib/silcclient/client_ftp.c.
984 * Added `disabled' field in the SilcChannelEntry in the server
985 to indicate if the server entry is disabled. Affected file
986 silcd/idlist.h, silcd/command[_reply].c.
988 * SILC server adds now /var/run/silcd.pid everytime it is
989 started. Affected file silcd/silcd.c.
991 * Added silc_server_packet_send_clients to send a packet to
992 the provided table of client entries. Affected file
993 silcd/packet_send.[ch].
995 * Fixed a crash in client resolving in client_prvmsg.c in
996 client library. Affected file lib/silcclient/client_prvmsg.c.
998 * Do not actually remove the client directly from ID cache
999 during SERVER_SIGNOFF, but invalidate it. This way we
1000 preserve the WHOWAS info for the client. Affected file
1001 silcd/server_util.c.
1003 * Fixed SERVER_SIGNOFF notify handling in the server. The
1004 server is now able to process incoming SERVER_SIGNOFF notify
1005 for a server that it doesn't even know about. It will remove
1006 the clients provided in the notify. Affected file
1007 silcd/packet_receive.c.
1009 * Check for partial packet in data queue after every packet that
1010 was found from the queue. Return and wait for more data if
1011 there is partial data in queue. Affected file is
1012 lib/silccore/silcpacket.c.
1014 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1016 * Added SilcClietFileError enum to indicate error in
1017 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1018 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1019 Affected files lib/silcclient/silcapi.h and

1022 * Check that newsize in silc_buffer_realloc is larger than
1023 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1025 * Added better monitor of file transfers. It now monitors
1026 key agreement protocol during the file transfer too. Added
1027 error reporting too. Affected files
1028 irssi/src/silc/core/silc-servers.c,
1029 irssi/src/fe-common/silc/module-formats.[ch].
1031 * Wrote a help file for FILE command.
1033 * Added silc_rng_global_get_byte_fast to get not-so-secure
1034 random data as fast as possible. Random data is read from
1035 /dev/urandom if available and from the SILC RNG if not
1036 available. It is used in padding generation. Affected file
1037 lib/silccrypt/silcrng.[ch].
1039 * All packets in client library are now processed synchronously.
1040 Optimized packet processing a lot. Affected file
1041 lib/silcclient/client.c.
1043 * All server connection packets are processing synchronously
1044 now in server, to optimize packet processing. Affected file
1047 * Include files are installed now only in Toolkit distribution
1048 if make install is given. Affected files: all Makefile.am's.
1050 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1052 * Assure that silc_client_notify_by_server_resolve does not
1053 resolve the client information multiple times. If it cannot
1054 be found by the first it cannot be found at all. Affected
1055 file lib/silcclient/client_notify.c.
1057 * Fixed WHOWAS command reply calling. Affected file
1058 lib/silcclient/command_reply.c.
1060 * Removed all references to silc_idlist_get_client from the
1061 Irssi SILC client since that call is internal call used by
1062 the library. The Irssi SILC client will use now client
1063 retrieval functions found in silcapi.h.
1065 * Fixed a bug in resolving nickname info before sending
1066 private message. It used freed memory. Affected file
1067 irssi/src/silc/core/silc-servers.c.
1069 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * Assure my_channels statistics cannot go negative in server.
1072 Affected files silcd/server.c, silcd/server_util.c.
1074 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1076 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1078 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1080 * Win32 Toolkit changes. Affected files
1081 win32/silc.dsw, win32/libsilc/libsilc.def,
1082 win32/libsilcclient/libsilc.def,

1084 lib/sftp/sftp_fs_memory.c.
1086 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1088 * Added silc_net_localip to return local host's IP address.
1089 Affected file lib/silcutil/silcnet.[ch].
1091 * If key exchange or rekey protocol is active for a connection
1092 parse all packets syncronously since there might be packets
1093 in packet queue that we are not able to process without first
1094 processing packets before them. Affected file silcd/server,
1095 lib/silcclient/client.c.
1097 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1098 whether library should continue processing the packet.
1099 Affected file lib/silccore/silcpacket.h.
1101 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1102 SilcSFTPMonitorData to SFTP server to monitor various
1103 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1104 lib/silcsftp/sftp_server.c.
1106 * Added silc_file_size to return file size. Affected file
1107 lib/silcutil/silcutil.[ch].
1109 * Implemented the file transfer support for the client library.
1110 Added preliminary support for simple client to client one-file
1111 transmission. Affected file lib/silcclient/client_ftp.c,

1123 silcd/server.c and silcd/packet_receive.c.
1125 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1127 * Renamed silc_file_read and silc_file_write to functions
1128 silc_file_readfile and silc_file_writefile. Added function
1129 silc_file_open and silc_file_close. Affected files
1130 lib/silcutil/silcutil.[ch].
1132 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1134 * Resolve the client info when received private message or
1135 channel message for a client which nickname we don't know.
1136 Affected files lib/silcclient/client_prvmsg.c and
1137 lib/silcclient/client_channel.c.
1139 * Do not crash in /KEY if client is not connected. Affected
1140 file irssi/src/silc/core/silc-channels.c.
1142 * Added SilcClientStatus field to the SilcClientEntry in the
1143 lib/silcclient/idlist.h.
1145 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1146 is incomplete and is being resolved, it won't be resolved
1149 Make sure also that USERS command reply does not resolve
1150 twice information. Affected file is
1151 lib/silcclient/command_reply.c.
1153 Make sure that silc_client_get_clients_by_list does not
1154 resolve twice same information.
1156 * Check for valid client->id in the silc_server_free_client_data.
1157 Affected file silcd/server.c.
1159 * Fixed /GETKEY nick@server not to crash if the server entry
1160 is not found. Affected file lib/silcclient/command.c.
1162 * Fixed the silc_server_check_cmode_rights to check the
1163 requested modes correctly. Affected file silcd/command.c.
1165 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Better checks for non-printable chars in nick added.
1168 Affected file silcd/command.c.
1170 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1172 * Call the silc_server_udpate_servers_by_server in the
1173 primary router that comes back online in the backup resuming
1174 protocol. Otherwise it routes packets wrong. Affected file
1175 silcd/server_util.[ch], silcd/server_backup.c.
1177 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1179 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1180 lib/silcutil/silcbuffmt.[ch].
1182 * Redefined the SILC packet header to include the padding
1183 length. Affected file lib/silccore/silcpacket.[ch].
1185 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1186 length for maximum padding up to 128 bytes). Affected
1187 file lib/silccore/silcpacket.h.
1189 * Removed all backwards support for old 0.5.x MAC thingies.
1190 The SILC packet header change makes it impossible to be
1191 backwards compatible.
1193 * Send the ENDING packet with timeout in the backup resuming
1194 protocol. This is to assure that all routers has connected
1195 to the primary router. Affected file silcd/server_backup.c.
1197 * Changed the RNG to take the first IV from random data. It
1198 used to take it from zero actually. Changed the RNG also
1199 to use /dev/urandom during session. /dev/random is used
1200 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1202 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * Changed the SILC packet header to have the first two bytes
1205 (the packet length) encrypted. Affected files aroung the
1206 code tree, lib/silccore/silcpacket.[ch]. Removed the
1207 SilcPacketCheckDecrypt callback. It is not needed anymore
1208 since the silc_packet_receive_process will determine now
1209 whether the packet is normal or special.
1211 * Implemented the unidirectional MAC keys. Affected files
1212 lib/silcske/silcske.c, silcd/protocol.c and
1213 lib/silcclient/protocol.c.
1215 * Implemented the packet sequence number to the MAC computation.
1216 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1217 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1218 lib/silcclient/protocol.c.
1220 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1222 * Allow backup router to announce servers. All servers
1223 announced by backup router are added to the global list
1224 automatically. Update hte server's socket to our primary
1225 router also when backup router announces a server.
1226 Affected file silcd/packet_receive.c.
1228 * Do not update the client->router in the function
1229 silc_server_udpate_clients_by_server if the client is on
1230 global list. We might fail to find any specific server
1231 for locally connected clients and local cell clients. They
1232 should still use the `from' and not `to' as client->router.
1233 This fixes backup router resuming protocol. Affected file
1234 silcd/server_util.c.
1236 * Decrease channel statistics count only if the channel
1237 deletion worked. Affected files are silcd/server.c and
1238 silcd/server_util.c.
1240 * Added silc_server_update_servers_by_server to update origin
1241 of all server entries. Used during backup router protocol.
1242 Affected files silcd/server_util.[ch], silcd/server.c. and
1243 silcd/backup_router.c.
1245 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1246 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1247 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1248 lib/silccrypt/silchmac.c.
1250 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Assure that router cannot reroute the same channel message
1253 to the sender. Affected file silcd/packet_receive.c.
1255 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Made better checks that the channel message is not sent
1258 to the router it came from. Affected file is
1259 silcd/packet_send.c. Fixed memory leak too.
1261 * Announce informations for incoming router connection, but
1262 only after checking if it is replaced by backup router.
1263 Affected file silcd/packet_receive.c.
1265 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1267 * Fixed the backup resuming protocol to work in multiple
1268 router environment. Affected file silcd/server_backup.c.
1270 * Route packet only to one router in the function
1271 silc_server_packet_send_to_channel. Affected file is
1272 silcd/packet_send.c.
1274 * Fixed silc_server_send_notify_dest to set the broadcast
1275 flag. Fixed the silc_server_send_notify_topic to actually
1276 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1277 Affected file silcd/packet_send.c.
1279 * Changed the SFTP Filesystem interface. Changed the
1280 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1281 the filesystem operation function. The SilcSFTPFilesystem
1282 is now a context that is allocated by all filesystem allocation
1283 functions and it already includes the operations structure
1284 and filesystem specific context. It is given as argument
1285 now to the silc_sftp_server_start. This made the interface
1286 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1287 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1289 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1291 * Changed the backup router adding and getting interfaces
1292 in the server. The router that will be replaced by the
1293 specified backup router is now sent as argument. Affected
1294 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1297 * Added silc_net_addr2bin_ne to return the binary form of
1298 the IP address in network byte order. Affected files
1299 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1301 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1303 * Check for existing server ID in silc_server_new_server
1304 and in silc_server_connect_to_router_final and remove the
1305 old entry if it exists. Affected file silcd/packet_receive.c,
1308 * Send the channel message always to only one router, either
1309 in upstream or downstream. Affected file is
1310 silcd/packet_send.c.
1312 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1314 * Wrote the definition of the backup resuming protocol to the
1315 protocol specification.
1317 * Removed one redundant channel key generation from normal
1318 server during joining procedure. Removed one redundant
1319 channel key sending from server to router during joining
1320 procedure. Affected file silcd/command.c.
1322 * Made minor bugfixes to the backup router resuming protocol.
1323 Affected file silcd/server_backup.c, server.c.
1325 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Added --disable-asm configuration option. Affected files
1328 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1331 * Implemented the backup resuming protocol that is used to
1332 resume the primary router position in the cell after the
1333 primary router comes back online. Affected files
1334 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1335 and silcd/server_util.[ch].
1337 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * Sleep two (2) seconds after sending QUIT command to server.
1340 Affected file lib/silcclient/command.c.
1342 * Assure that if outgoing data buffer is pending do not force
1343 send any data. Affected file silcd/packet_send.c.
1345 * Assure that if outgoing data buffer is pending do not force
1346 send any data. Affected file lib/silcclient/client.c.
1348 * Implemented the backup router support when the primary router
1349 goes down. The servers and routers can now use the backup
1350 router as new primary router without loosing connectivity.
1352 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1354 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1355 in the server to indicate disabled entry. All data read
1356 from the connection will be ignored and no data is sent
1357 for entry that is disabled. Affected files are
1358 silcd/idlist.h, silcd/server.c.
1360 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Created SFTP client and server test programs in the
1363 lib/silcsftp/tests directory.
1365 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1367 * Implemented memory filesystem (virtual filesystem) for
1368 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1371 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Implemented the SFTP (SSH File Transfer Protocol) to the
1374 lib/silcsftp. It includes SFTP client and SFTP server
1377 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1379 * Moved lib/silccore/silcprotocol.[ch] to the
1380 lib/silcutil library.
1382 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1383 take variable argument list pointer as argument. Affected
1384 file lib/silcutil/silcbuffmt.[ch].
1386 * Added silc_buffer_set function that is used to set data
1387 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1388 Affected file lib/silcutil/silcbuffer.h.
1390 * Changed various routines in the core library to use the new
1391 silc_buffer_set instead of allocating new buffer only for
1394 * Added 64-bit value formatting and unformatting support to the
1395 silc_buffer_[un]format routines. Affected file is
1396 lib/silcutil/silcbuffmt.[ch].
1398 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1399 to includes/bitmove.h.
1401 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1403 * Fixed channel user mode saving in client library. Affected
1404 file lib/silcclient/command[_reply].c.
1406 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1408 * Defined the file transfer to the SILC Protocol. Added
1409 new packet type SILC_PACKET_FTP and defined File Transfer
1410 Payload. The mandatory file transfer protocol is SFTP
1411 (SSH File Transfer Protocol). Affected file in addition
1412 of the internet draft is lib/silccore/silcpacket.h.
1414 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1415 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1416 is used as part of backup router protocol when the primary
1417 router of the cell is back online and wishes to resume
1418 the position as primary router.
1420 * Redefined the MAC generation keys in the protocol. The
1421 same key is not used anymore in both direction. Both
1422 direction will now use different keys for sending and
1423 receiving. This fixes a potential security flaw. This
1424 change causes incompatibilities in the protocol.
1426 * Redefined also the MAC computation from the packet.
1427 An packet sequence number is now added to the MAC
1428 computation. This prevents possible replay attacks against
1429 the protocol. This change too causes incompatibilities
1432 Added `sequence' field to the SilcPacketContext to hold
1433 the current sequence number for the packet.
1435 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1437 * Added `created' field to the SilcIDListData in the file
1438 silcd/idlist.h to indicate the time when the entry was
1441 * Added `created' field to the SilcChannelEntry too. Affected
1442 file silcd/idlist.h.
1444 * Added `creation_time' aguments to all the announcement functions
1445 in the server. If it is provided then only the entries that
1446 was created after the provided time frame are actually
1447 announced. Affected file silcd/server.[ch].
1449 * The protocol says that the Channel ID's IP address must be
1450 based on the router's IP address. Added check for this in
1451 the silc_server_new_channel when processing incoming New Channel
1452 Payload. Affected file silcd/packet_receive.c.
1454 * Print out the correct version with --version in SILC client.
1455 Affected file irssi/src/silc/core/silc-core.c.
1457 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Fixed WHOWAS command to check for completnes of the client
1460 entry always, not just when the command is coming from client.
1461 Affected file silcd/command.c.
1463 * Added new function silc_server_packet_queue_purge to purge the
1464 outgoing data queue to the network. After the function returns
1465 it is guaranteed that the outgoing packet queue is empty.
1466 Affected file silcd/packet_send.[ch].
1468 * Purge the outgoing packet queue in the rekey protocol's final
1469 callback to assure that all rekey packets go to the network
1470 before quitting the protocol. Affected file silcd/server.c.
1472 * Added silc_client_packet_queue_parse as similar function as
1473 in server to the client library. The affected file is
1474 lib/silcclient/client.c.
1476 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Splitted silcd/server.c and created silcd/server_util.[ch]
1479 for utility functions.
1481 * Added new socket flag SILC_SF_DISABLED to indicate that the
1482 connection is open but nothing can be sent to or received from
1483 the connection. Affected file lib/silcutil/silsockconn.[ch].
1484 The checking for disabled socket is checked in the low level
1485 silc_socket_write and silc_socket_read functions.
1487 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * Allow only nicknames and channel names that fits into the
1490 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1492 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1494 * When processing JOIN command reply in server check that if
1495 the channel exists in our global list we'll move it the local
1496 list. Affected file silcd/command_reply.c.
1498 * Fixed the check whether client is joined on the channel already
1499 in JOIN command. Affected file lib/silcclient/command.c.
1501 * Fixed the JOIN command reply to check whether the channel
1502 already exists. Affected file lib/silcclient/command_reply.c.
1504 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1506 * Added silc_ske_status_string to map the SKE error numbers
1507 to readable strings. The affected files are
1508 lib/silcske/silcske[_status].[ch].
1510 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1512 * Do not show the private channels on the WHOIS channel list
1513 as it is not allowed by the protocol. The affected file is
1516 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1518 * Assure that the packet length digged from the actual packet
1519 is something sensible in the silc_packet_decrypt_rest_special
1520 in lib/silccrypt/silcpacket.c.
1522 * Free and NULL the allocated pointer in silc_hmac_alloc if
1523 the HMAC allocation fails. The affected file is
1524 lib/silccrypt/silchmac.c.
1526 * Print the selected security properties to the log files in
1527 the server. Affected file silcd/protocol.c.
1529 * Add SKE's reference counter even if calling the completion
1530 callback manually. Otherwise it goes negative, although it
1531 does not cause any problems. The affected file is
1532 lib/silcske/silcske.c.
1534 * Remove the client entry with short timeout after giving the
1535 KILL command. Affected file lib/silcclient/command.c.
1537 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1538 case all found clients are already disconnected (WHOWAS would
1539 found them) in the server. Affected file silcd/command.c.
1541 * Update the last_receive (time of last data received) to be
1542 updated only when received private or channel message so that
1543 the idle time showed in WHOIS makes more sense.
1545 * Added boolean field `valid' in to the SilcClientEntry in the
1546 client library to indicate whether the entry is valid or not.
1547 This fixes the nickname change bug on channel when changing
1548 the nickname to be same than the old (like nick to Nick) the
1549 nickname formatter doesn't set the new nick anymore to Nick@host.
1550 Affected file lib/silcclient/idlist.[ch].
1552 * Now actually fixed the nickname changing on disconnection.
1553 Added new function silc_change_nick to the Irssi SILC Client.
1554 Affected file irssi/src/silc/core/client_ops.c,
1555 irssi/src/silc/core/silc-nicklist.[ch].
1557 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1559 * Check that the public key exists in the GETKEY command before
1560 trying to encode it. Affected file silcd/command.c.
1562 * Print some notifications on received public keys with GETKEY
1563 command in the Irssi SILC Client. Affected files are
1564 irssi/src/fe-common/silc/module-formats.[ch],
1565 irssi/src/silc/core/client_ops.c.
1567 * Use IDENTIFY command to resolve the server information in the
1568 GETKEY command instead of INFO command. Affected file
1569 lib/silcclient/command.c.
1571 * All command reply functions in the client library now calls
1572 the pending command reply callbacks even if an error has
1573 occurred. The server has done this a long time and now it was
1574 time to move the client library to this as well. Now all
1575 errors can be delivered back to the pending command reply
1576 callbacks if necessary. Affected files are
1577 lib/silcclient/command[_reply].[ch].
1579 * Change the nickname on disconnection back to the username
1580 because in reconnect the server will enforce it to it anyway.
1581 Affected file irssi/src/silc/core/silc-servers.c.
1583 * Fixed a config file parsing bug in the Irssi SILC client.
1584 Affected file irssi/src/silc/core/clientconfig.c.
1586 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1588 * When printing the channel mode on JOIN, verify that the
1589 channel key and channel's HMAC are valid. Affected file
1590 irssi/src/silc/core/client_ops.c.
1592 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1594 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1595 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1596 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1598 * Removed channel key rekey task deleting from the function
1599 silc_server_save_channel_key. Affected file silcd/server.c.
1600 Added explicit timeout task context instead that is used to
1601 delete the task if we are registering a new task before the
1602 new task has elapsed.
1604 * When channel key rekey occurs the client library now saves
1605 the old channel key for a short period of time (10 seconds) and
1606 is able to use it in case some is still sending channel
1607 messages encrypted with the old key after the rekey. Affected
1608 file lib/silcclient/[idlist.h|client_channel.c].
1610 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1612 * Added check to the silc_server_new_id_real to not accept
1613 new ID if it is the sender's own ID. Affected file is
1614 silcd/packet_receive.c.
1616 * Assure that we do not announce ourself or the one we've
1617 sending our announcements when we're router and are announcing
1618 servers to our primary router. Affected file silcd/server.c.
1620 * Fixed silc_server_command_identify_check_client to assemble
1621 correct WHOIS packet. It send corrupted WHOIS packet and
1622 caused problem with router to router connections. Affected
1623 file silcd/command.c.
1625 Fixed also silc_server_command_whois_check the same way
1626 as for the IDENTIFY command.
1628 * Added new SilcIDListStatus to the server in the SilcIDListData
1629 structure. The status now includes the current status of
1630 the entry (like registered, resolved etc.). Affected file
1631 silcd/idlist.[ch]. Defined a bunch of different status types
1632 as well. This replaced the old boolean registered field as well.
1634 Added resolve_cmd_ident field to the SilcClientEntry structure
1635 too so that if the entry is for example being resolved so
1636 another command may attach to the same pending command reply
1637 without requiring to resolve the same entry again. This concept
1638 should optimize the WHOIS and the IDENTIFY resolving under
1639 heavy load by taking away unnecessary resolving for entries
1640 that are being resolved already.
1642 Added support for adding multiple pending commands for one
1643 command idenfier. Affected file silcd/command[_reply].[ch].
1645 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1646 before deleting the data. Otherwise the hash table will have
1647 freed data in comparison functions. Affected file is
1648 silcd/command_reply.c.
1650 * Fixed silc_idlist_replace_client_id to add the new entry to
1651 the cache with NULL nickname. Otherwise there will be invalid
1652 memory as the nickname after the nickname is freed. Affected
1653 file silcd/packet_receive.c.
1655 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1656 saved into wrong slots because the previous number of entries
1657 was not taken into account. Affected file silcd/idlist.c.
1658 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1660 * If we are router and we receive JOIN notify to a channel that
1661 does not have any users then notified client is marked as the
1662 channel founder, as it is it. The affected file is
1663 silcd/packet_receive.c
1665 * Added to the extended hash table API's table_del_*ext functions
1666 the destructor as argument too, so that the caller can decide
1667 which destructor to use or whether to use destructor at all.
1668 Affected file lib/silcutil/silchashtable.[ch].
1670 * Fixed ID Cache purging. It actually deleted the entries from
1671 the hash table after the data was freed. The hash table ended
1672 up comparing freed memory. The affected file is
1673 lib/silccore/silcidcache.c.
1675 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1677 * Fixed Irssi SILC client's KILL command's HELP syntax.
1679 * The USERS command now resolves the detailed user information
1680 if the userinfo field is missing. Affected file is
1681 lib/silcclient/command_reply.c.
1683 * Do not print error in silc_file_read if the read file does
1684 not exist. Just silently return NULL. Affected file is
1685 lib/silcutil/silcutil.c.
1687 * Fixed the silc_log_output to not wine about NULL filename
1688 and to not create some bogus " " filename. Affected file is
1689 lib/silcutil/silclog.c.
1691 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1693 * Fixed various printing bugs on the user interface in the
1694 Irssi SILC Client. Minor changes that were forgotten from
1697 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1699 * Fixed the configure.in.pre and the compilation and distribution
1700 environment to support the new autoconf 2.52. That version is
1701 now required to compile the CVS trunk.
1703 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1705 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1706 to generally parse user@fqdn format strings. Affected file
1707 lib/silcutil/silcutil.c.
1709 * Added nickname_format and nickname_force_format fields to the
1710 SilcClientParams structure. The first one defines the format
1711 for the nicknames that the library will enforce if the receives
1712 multiple same nicknames. The second one is boolean value and
1713 can be used to force the library to always enforce the format
1714 to the nicknames regardles whether there are multiple nicknames
1715 or not. This configurable formatting was employed to flexibly
1716 support accessing multiple nicknames from the user interface.
1717 The userinterface can now set the nicknames to what ever format
1718 they prefer. Affected file lib/silcclient/silcapi.h.
1720 Added function silc_client_nickname_format to the file
1721 lib/silcclient/idlist.c. It performs the nickname formatting.
1723 Added new field `hostname´ to the SilcClientEntry context.
1724 It holds the hostname of the client. Affected file is
1725 lib/silcclient/idlist.h.
1727 * Irssi SILC Client sets the nicknames in nick@hostn format.
1728 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1729 irssi/src/silc/core/silc-core.c.
1731 The WHOIS printing now also shows both the real nickname and
1732 the formatted nickname so that user knows how to access the
1733 user if there are multiple same nicknames cached. Affected
1734 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1735 printing formatting too to take the hostname now as a separate
1736 argument. The Affected file is
1737 irssi/src/fe-common/silc/modules-formats.[ch].
1739 * Changed the silc_client_get_clients_local to accept the formatted
1740 nickname as argument. It accepts the real nickname too but the
1741 formatted nickname can be used to find the true entry from
1742 multiple entries. Affected file lib/silcclient/silcapi.h and
1743 lib/silcclient/idlist.c.
1745 * Added nickname_format_parse field to the SilcClientParams.
1746 It is a callback function provided by the application to parse
1747 the nickname out of the formatted nickname string. The library
1748 calls it to get the nickname from the formatted string. Since
1749 the application generally knows better the format of the nickname
1750 string it parses it instead of the library, even though library
1751 encodes the formatted string. If the callback function is not
1752 provided then the library will use the string as is. The
1753 affected file is lib/silcclient/silcapi.h.
1755 * All the nickname strings passed to the client library in
1756 commands are now expected to be formatted nickname strings.
1757 If the command does not support the formatted nickname string
1758 it will assume that the sent string is the actual nickname.
1759 Affected file lib/silcclient/command.c.
1761 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Added public key authentication support to OPER and SILCOPER
1764 commands in the client library. Affected file is
1765 lib/silcclient/command.c.
1767 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1769 * Changed the get_auth_methdod client operation to be asynchronous.
1770 It can be async if the application resolves the authentication
1771 method from the server during the negotiation. Added new
1772 SilcGetAuthMeth completion callback that the application will
1773 call after resolving the authentication method.
1775 Added function silc_client_request_authentication_method that
1776 the application can use to resolve the authentication method
1777 from the server. Added also SilcConnectionAuthRequest callback
1778 that the library will call after the server has replied. The
1779 application can call this function if it does not know the
1780 current authentication method.
1782 Affected files are lib/silcclient/client.c and
1783 lib/silcclient/silcapi.h.
1785 * The Irssi SILC client now automatically resolves the authentication
1786 method incase any configuration information is not present (and
1787 currently there never is). The affected file is
1788 irssi/src/silc/core/client_ops.c.
1790 * Fixed public key authentication from the client library.
1791 Affected file lib/silcclient/protocol.c. Changed also the
1792 protocol specification about the public key authentication in
1793 the connection authentication protocol. The actual data to be
1794 signed is now computed with a hash function before signing.
1796 * Fixed the public key authentication from the server as well.
1797 Affected file silcd/protocol.c.
1799 * Removed the mlock()'s from the memory allocation routines.
1800 Affected file lib/silcutil/silcmemory.c. The ./configure does
1801 not check anymore for the mlock(). Affected file is
1804 * Fixed USERS command in server to allow the execution of the
1805 command for private and secret channels if the client sending
1806 the command is on the channel. Affected file silcd/command.c.
1808 * Fixed silc_client_get_clients_local to return the clients
1809 count correctly. It could return wrong value. Affected file
1810 lib/silcclient/idlist.c.
1812 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1815 types. The assembler optimizations seemed not to like 64-bit
1816 data types. The assmebler optimizations thus are now enabled
1817 also for BSD systems as opposed to only enable them for Linux.
1819 * Do not check for threads at all on BSD systems. Affected
1820 file configure.in.pre.
1822 * Removed -n and -h options from the Irssi SILC Client since
1823 they are not used in silc.
1825 * Fixed the prime generation to assure that the first digit
1826 of the generated random number is not zero since our conversion
1827 routines does not like number strings that starts with zero
1828 digit. If zero digit is seen the random number is regenerated.
1829 This caused some corrupted RSA keys when the zero first digit
1830 was met. Affected file lib/silcmath/silcprimegen.c.
1832 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1834 * Fixed WIN32 configuration in the ./configure script.
1835 Fixed to include xti.h on environments that has it.
1836 Patches by Carsten Ilchmann and andrew.
1838 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Changed the silc_id_create_client_id to be collision
1841 resistant. It is now assured that there cannot be created
1842 two same client ID's. I suspect that some weird bugs in
1843 the server were actually caused by duplicate Client IDs.
1844 Affected file silcd/serverid.[ch]. A router receiving
1845 new ID now also assures and informs the sending server
1846 if the ID caused collision.
1848 * Changed the silc_id_create_channel_id to also assure that
1849 there are no collisions.
1851 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Statement about ignoring the Mutual Authentication flag when
1854 performing rekey with PFS was a bit misleading. It is ignored
1855 if it was set in the initial negotiation, it cannot be even
1856 set in the rekey. Fixed in the ke-auth draft. Started the
1857 new versions of the protocol drafts in the doc/.
1859 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * Fixed a bug in silc_client_command_identify_save when saving
1862 new channel information. The channel name was no duplicated
1863 and caused crash on exit. Affected file is
1864 lib/silcclient/command_reply.c.
1866 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * Fixed the getkey command handling in the server. Send just
1869 empty OK reply to the sender if the key could not be fetched
1870 (but everything else was ok, like the key just was not available).
1871 Changed the public key parameter to optional in the protocol
1872 specs so that empty OK reply can be sent. Affected file
1875 Added a message to Irssi SILC client to tell to user if the
1876 server did not return a public key.
1878 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Fixed a channel key regeneration bug. It registered new
1881 timeout tasks exponentially until all system resources were
1882 used. Affected file silcd/server.c.
1884 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Added the SILC Document generator to the scripts/silcdoc.
1887 It can be used to generate the Toolkit Reference Manual out
1888 of the source tree. Internally it will also use the RoboDoc
1889 generator now imported in util/robodoc.
1891 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Added couple of return's in rekey protocol if error orccurred
1894 during the protocol. The execution must be terminated.
1895 Affected file silcd/protocol.c. Also, terminate the protocol
1896 always with timeout.
1898 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * The client's Client ID was created initally from the wrong
1901 nickname (it could have been in format nick@host) in the
1902 silc_server_new_client. Affected file silcd/packet_receive.c
1904 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1906 * Added some SILC_LOG_ERROR's to various error conditions
1907 if client could not be added to ID cache. Affected files
1908 silcd/packet_receive.c and silcd/server.c.
1910 * When client's sock->user_data is freed, NULL also the
1911 client->router and client->connection pointers. Added check
1912 for these pointers being NULL to various places around the
1913 code. Affected file silcd/server.c.
1915 * Added client->data.registered == TRUE checks to various
1916 places around the code to assure that unregistered client's
1917 are not handled when it is not allowed. Affected file
1920 * Added `bool registered' fields to all
1921 silc_idlist_[server|client]_get_* routines to indicate whether
1922 the fetched client needs to be registered or not. Affected
1923 file silcd/idlist.[ch].
1925 * Add your own entry as registered to the ID cache in the
1926 server. Affected file server.c.
1928 * Fixed a bug in silc_server_new_server. The SilcServer was
1929 set as the new server's context instead of SilcServerEntry.
1930 This naturally caused some weird bugs.
1932 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Do not delete the channel rekey task when adding it
1935 for in silc_server_create_channel_key.
1937 * Changed the silc_server_create_channel_key to return
1938 TRUE or FALSE to indicate the success of the channel key
1941 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1943 * Fixed MSVC++ project files and added missing files to
1944 Makefiles under win32/.
1946 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1948 * Do not add TCP_NODELAY flag if the operating system
1949 does not have it defined. Affected files are
1950 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1952 * Fixed buffer overflow from Irssi SILC Client. Affected
1953 file irssi/src/fe-common/core/themes.c.
1955 * Fixed double free in client library in the file
1956 lib/silcclient/client.c when disconnecting from server.
1958 * Applied double free patch from cras to Irssi SILC client.
1959 Affected files irssi/src/core/[modules/expandos].c
1961 * Fixed the disconnection handling to Irssi SILC Client.
1962 The application must call silc_client_close_connection
1963 in ops->connect client operation in case of failure of
1964 the connection. Affected file is
1965 irssi/src/silc/core/client_ops.c.
1967 * Do not set sock->protocol to NULL in the function
1968 silc_client_close_connection after executing the protocol's
1969 final callback since the sock might not be valid anymore.
1970 Affected file lib/silcclient/client.c.
1972 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1974 * Do not enable SILC_THREADS if the linking with libpthread
1975 did not happen. Affected file configure.in.pre.
1977 * Added notion to protocol specification that server must
1978 verify the sent authentication payload with CMODE when
1979 setting the channel founder key. Implemented it to the
1980 server. Affected file silcd/command.c.
1982 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1984 * Added _EXTRA_DIST SILC distribution variable to the
1985 distributions file. It is used to conditionally add extra
1986 files or directories to the specific distribution. Affected
1987 files ./prepare, Makefile.am.pre and distributions.
1989 Removed the `_' from the start of the distribution names.
1992 * Added README.WIN32 for instructions to compile the Toolkit
1995 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Fixed a double free in disconnection in the server. Affected
1998 file is silcd/server.c.
2000 * Fixed the lib/silcske/groups.c to work now also with GMP
2001 MP library. The string conversion did not work when using
2002 specific base and the base is indicated in the string as well.
2004 * Created win32/ directory which now includes MSVC++ specific
2005 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2006 It will appear only in the toolkit distribution
2008 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Changed the key material distribution function in case when
2011 the hash output is too short. The data is now concatenated
2012 a bit differently than it used to. Made the change to the
2013 SKE protocol specification.
2015 * Added better GMP detection to configure.in.pre. A patch
2018 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * Fixed a minor bug in SKE that might cause some problem on
2021 some platforms. Affected file lib/silcske/silcske.c.
2023 * Added the cookie checking for initiator in the SKE. It checks
2024 that the responder returns the sent cookie unmodified. The
2025 affected file is lib/silcske/silcske.c. Added new SKE
2026 error type INVALID_COOKIE that can be sent during the
2027 negotiation. Fixed some memory leaks as well.
2029 * Added the "invalid cookie" error message to Irssi SILC client's
2032 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Added `task_max' field to the SilcClientParams to indicate
2035 the maximum tasks the scheduler can handle. If set to zero,
2036 default values are used. Affected file lib/silcclient/silcapi.h.
2038 * Fixed memory leaks in silc_client_close_connection. Affected
2039 file lib/silcclient/client.c.
2041 * Added silc_client_del_client_entry to client library to free
2042 all memory of given client entry. Affected file is
2043 lib/silcclient/idlist.[ch].
2045 * Added new functions silc_client_del_channel and
2046 silc_client_del_server to delete channel and server entries.
2047 Affected file lib/silcclient/[silcapi.h/idlist.c].
2049 * Removed silc_client_del_client_by_id from silcapi.h.
2051 * Fixed the INFO command to return the server's own info
2052 correctly when querying by Server ID. Affected file is
2055 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2057 * Removed the non-blocking settings in WIN32 code in the
2058 silc_sock_[read/write] and added SleepEx instead. Affected
2059 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2060 of input data is now checked with FIONREAD and ioctlsocket.
2062 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2064 * Call silc_schedule_task_del_by_context in the
2065 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2066 Affected file lib/silccore/silcprotocol.c.
2068 * Call silc_protocol_cancel for active protocols in the
2069 silc_server_close_connection if the funtion
2070 silc_server_free_sock_user_data has not been called.
2071 Affected file silcd/server.c.
2073 * Generic tasks cannot be deleted using the del_by_fd
2074 task deleting function since generic tasks does not match
2075 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2077 * Added a notion to SILCOPER help file that the SILCOPER works
2078 only on router server, not on normal server.
2080 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2082 * Added for WIN32 support for the new scheduler as well.
2083 Affected file lib/silcutil/win32/silcwin32schedule.c.
2085 * Fixed the SHA1 implementation to work on various platforms.
2087 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2089 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2090 API. It is part of the scheduler now. Everything else is
2091 as previously but some functions has changed their names.
2092 Checkout the lib/silcutil/silcschedule.h for the interface.
2093 Updated all applications to use the new interface. Affected
2094 files are lib/silcutil/silcschedule.[ch].
2096 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Found a bug in the SKE implementation. The HASH value,
2099 specified by the protocol, was not computed correctly. The
2100 public key of the responder was not added to the computation
2101 even though it is mandatory. Affected file lib/silcske/silcske.c.
2102 This unfortunately causes incompatibilities with older
2103 clients and servers.
2105 * Added WIN32 specific network init and uninit functions:
2106 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2107 the Winsock2. Affected file lib/silcutil/silcnet.h and
2108 lib/silcutil/win32/silcwin32net.c.
2110 * Set the socket always to nonblocking mode on WIN32 after
2111 reading data or writing data. Affected file is
2112 lib/silcutil/win32/silcwin32sockconn.c.
2114 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2116 * Fixed various compilation problems under WIN32. Affected
2117 files lib/silcutil/win32/silcwin32thread.c and
2118 lib/silcutil/win32/silcwin32schedule.c.
2120 * Removed all _internal.h #includes from public header
2121 files. Internal headers must never be included from
2124 Removed also the lib/silcske/payload_internal.h file.
2126 * All include files that may be needed (public and some others
2127 included by the public headers) by application developers are
2128 now copied to the ./includes directory. It does not copy any
2129 internal headers. Affected file Makefile.defines.pre and all
2130 Makefile.am's under lib/ and subdirs.
2132 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Do not change the ~/.silc directory's permissions automatically.
2135 Affected file irssi/src/silc/core/clientutil.c.
2137 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2139 * Do not cancel the protocol in silc_server_close_connection
2140 it might cause recursion. Now cancelled in the function
2141 silc_server_free_sock_user_data. Affected file silcd/server.c.
2143 * Fixed the silc_server_remove_clients_by_server to regenerate
2144 the channel keys correctly finally. Added also new function
2145 silc_server_remove_clients_channels to actually do it.
2146 Affected file silcd/server.c.
2148 * Fixed the silc_server_new_channel to not crash by giving
2149 wrong router to the new channel. Affected file is
2150 silcd/packet_receive.c.
2152 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2155 which is given as argument to the silc_client_alloc now.
2156 It can be used to configure the client and set various parameters
2157 that affect the function of the client.
2159 * The USERS command in server did not check whether the channel
2160 is private or secret. Affected file silcd/command.c.
2162 * Added new argument to the USERS command in protocol specification.
2163 The USERS command now can take the channel name as argument
2164 as well. Added support for this in client and server and
2165 updated the protocol specs.
2167 * Completed the GETKEY command in client. It can be now used
2168 to fetch also servers public key not only some clients.
2169 Affected files lib/silcclient/command[_reply].c.
2171 * Added silc_client_get_server to return server entry by the
2172 server name. Affected files lib/silcclient/silcapi.h and
2175 * Redefined the IDENTIFY command in protocol specification to be
2176 more generic. It now can be used to query information about
2177 any entity in the SILC Network, including clients, servers and
2178 channels. The query may be based either the entity's name
2179 or the ID. Added support for this in both client and server.
2181 Affected files silcd/command.c and lib/silcclient/command.c
2182 and command_reply.c.
2184 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2185 the _from_client and _from_server functions. Affected file
2188 * Added silc_client_get_channel_by_id_resolve to the file
2189 lib/silcclient/silcapi.h to resolve channel information by
2190 its ID. Added also silc_client_get_channel_by_id that
2191 does not resolve it from the server.
2193 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Added SilcServerEntry context into the client library
2196 to represent one server. The INFO command now allocates
2197 these to save the resolved server info. For now on the
2198 client library will also keep information about servers,
2199 connected and resolved with INFO.
2201 The INFO command now allocates the SilcServerEntry context
2202 and saves the server info there. The COMMAND_REPLY in
2203 the INFO now returns the parameters to application in
2204 same order as defined in the protocol specification.
2206 The entries are cached in the client->server_cache.
2208 * The INFO command is now issued after received the Client ID
2209 from the server. Affected file lib/silcclient/client.c.
2211 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2212 to the application as the mode changer might be server.
2213 It is guaranteed that NULL is not returned anymore to the
2214 application. Affected file lib/silcclient/client_notify.c.
2216 The ID Type is now also passed to the application so that
2217 it can check whether the returned entry is SilcClientEntry
2220 Added new function silc_client_get_server_by_id to return
2221 the server entry by ID. Affected files are the
2222 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2224 * Do not create the channel in the Irssi SILC Client when issuing
2225 the JOIN command but when received the sucessful JOIN command
2226 reply. Otherwise the channel might get created even though we
2227 could not join it. The Affected file is
2228 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2230 * Fixed a channel joining bug in router. The router must also
2231 check the channel modes, invite and ban lists etc. when serving
2232 the JOIN command sent by normal server. Affected file is
2233 silcd/command.c. The router now resolves the client's
2234 information from the server who sent the JOIN command if it
2235 does not know it, and processes the JOIN command only after
2238 * Changed the SilcCommandCb to take new argument; void *context2.
2239 Affected file lib/silccore/silccommand.h
2241 The second argument in the command callbacks in the server now
2242 includes the SilcServerCommandReplyContext if the command was
2243 called as pending command callback from the command reply.
2244 Otherwise it is NULL. When called as pending the status of the
2245 command reply will be checked and if it was erronous the
2246 error will be sent to the original sender of the command.
2247 This way the client always receives the error messages even
2248 though the server was actually the one who received the error
2249 when it resent the command to router, for example. Affected
2250 files silcd/command[_reply].[ch].
2252 * Fixed sending WHOWAS command's error message to client if
2253 the requested client could not be found. It was missing.
2256 * Changed the CMODE and CUMODE commands reply arguments in the
2257 protocol specification. The Channel ID is now sent in both
2258 of the commands to identify the channel. Implemented this
2259 new feature to the client and server. Affected files
2260 lib/silcclient/command_reply.c and silcd/command.c.
2262 * Made better checks for invite and ban lists in the JOIN
2263 command in server. Affected file silcd/command.c.
2265 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * The server now performs the incoming host IP/DNS lookup
2268 using the silc_socket_host_lookup and thus does not block
2269 the server anymore. Affected file silcd/server.c.
2271 * Completed the multi-thread support for SILC Scheduler in
2272 the lib/silcutil/silcschedule.c.
2274 * Fixed the configure.in.pre to detect the pthread correctly
2277 * Fixed a deadlock in silc_task_queue_wakeup in the file
2278 lib/silcutil/silctask.c.
2280 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Added new function silc_schedule_wakeup that is used in
2283 multi-threaded environment to wakeup the main thread's
2284 schduler. It needs to be used when a thread adds a new task
2285 or removes a task from task queues. After waking up, the
2286 scheduler will detect the task queue changes. If threads
2287 support is not compiled in this function has no effect.
2288 Implemented the wakeup mechanism to both Unix and WIN32
2289 systems. Affected files are lib/silcutil/silcschedule.[ch],
2290 lib/silcutil/unix/silcunixschedule.c and the
2291 lib/silcutil/win32/silcwin32schedule.c.
2293 * Added new function silc_task_queue_wakeup to wakeup the
2294 scheduler by the specified task queue. Affected file
2295 lib/silcutil/silctask.[ch].
2297 * The silc_socket_host_lookup_start now wakes up the scheduler
2298 after adding the timeout task. Affected file is
2299 lib/silcutil/silcsockconn.c.
2301 * The silc_socket_host_lookup is synchronous now if the threads
2302 support is not compiled in. However, the callback is still
2303 called asyncronously through the scheduler, anyway. Affected
2304 file lib/silcutil/silcsockconn.c.
2306 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Added new function silc_socket_host_lookup to perform
2309 asynchronous IP and FQDN lookups for the socket connection.
2310 Affected files lib/silcutil/silcsockconn.[ch].
2312 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2315 that may or may not compile the mutex support in.
2317 Changed the silc_mutex_alloc interface. It allocates the
2318 mutex now to the sent pointer and returns TRUE or FALSE.
2320 Affected file lib/silcutil/silcmutex.h.
2322 * Wrote the SILC Task Queue interface to support multi-threads.
2323 Affected file lib/silcutil/silctask.[ch].
2325 * Wrote the SILC Scheduler to support multi-threads. Affected
2326 file lib/silcutil/silcschedule.c.
2328 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2331 in lib/silcutil/win32/.
2333 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2335 * Defined SILC Mutex API and SILC Thread API and implemented
2336 them for Unix. Affected files are
2337 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2338 lib/silcutil/unix/silcunixmutex.c and
2339 lib/silcutil/unix/silcunixthread.c.
2341 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2343 * Fixed the silc_server_remove_clients_by_server's channel
2344 key re-generation. The hash table handling was incorrect
2345 and would not work with many channels. Affected file is
2348 * Fixed some memory leaks around the server code.
2350 * Rewrote the silc_server_get_users_on_channel to support IPv6
2351 based Client ID's. Affected file silcd/server.c.
2353 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2354 specification. However, a separate document must be written
2355 to define the detailed signing procedure and the payload
2356 associated with the flag. Defined the flag to the
2357 lib/silccore/silcchannel.h as well.
2359 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2361 * Changed the dynamic tables to static size tables in the
2362 lib/silccrypt/silchmac.c.
2364 * Removed GCC dependencies from the code. A patch by cras.
2366 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2368 * Do not show the error "Error receiving packet bla bla"
2369 in server if it really was not an error (-2 means that reading
2370 is pending). Affected file silcd/server.c.
2372 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * Fixed a possible crash in silc_server_remove_clients_by_server
2375 in silcd/server.c. Fixed there also some memory leaks.
2377 * Fixed the silc_idlist_replace_client_id. It could replace
2378 wrong key in the hash table. Affected file silcd/idlist.c.
2380 * Do not check whether there are global users on the channel
2381 if the channel->global_users is FALSE. Affected functions
2382 silc_server_remove_from_one_channel and
2383 silc_server_remove_from_channels in silcd/server.c. Also,
2384 do not check if the removed client is local as we can be
2385 sure that global client was not removed from the channel
2386 and checking for global users is not needed.
2388 * The silc_server_remove_clients_by_server now re-generates
2389 the channel keys correctly for those channels that had
2390 clients removed from them. Affected file silcd/server.c.
2392 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2394 * Found the reason of random crashes in the server. We weren't
2395 ignoring the SIGPIPE signal (which can be sent in write())
2396 and it crashed the server. Affected file silcd/silcd.c.
2398 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * Assure that sock->user_data is not NULL in the function
2401 silc_server_packet_send in silcd/packet_send.c.
2403 * Disconnect the remote connection if it could not be added
2404 to any ID lists in the server. The affected file is
2407 * Check in silc_server_packet_send[_real/dest] that the
2408 socket is not disconnecting and ignore the data if it is.
2409 Affected file silcd/packet_send.c.
2411 * Define inline to __inline on native WIN32 compilation.
2412 Affected file includes/silcwin32.h.
2414 * Added some explicit type casts for inline code since MSVC
2415 require them. Affected files lib/silcutil/silcbuffer.h,
2416 lib/trq/silcdlist.h and lib/trq/silclist.h.
2418 * Print warning in log files from now on if the packet
2419 decryption fails. Affected file silcd/server.c.
2421 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2423 * Changed the `say' client operation's interface to accept
2424 new `type' argument to indicate the type of the message sent
2425 by the library. The application may filter the library's
2426 messages according the type. The affected file is the
2427 lib/silcclient/silcapi.h.
2429 * Added two new functions to lib/silcclient/silcapi.h:
2430 silc_client_del_client and silc_client_del_client_by_id.
2431 Affected file lib/silcclient/idlist.c.
2433 * Moved the clientincludes.h from includes/ to silc/ and
2434 serverincludes.h from includes/ to silcd/.
2436 * The modes for the CMODE and CUMODE are now passed as
2437 uint32 for application with COMMAND_REPLY. The affected
2438 file is lib/silcclient/command_reply.c.
2440 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2442 * /WHOIS without arguments shows client's own information.
2443 Affected file lib/silcclient/command.c.
2445 * Changed PING to not accept any arguments. The specs
2446 says that client can ping only the connected server so
2447 requiring an argument is not needed. Affected file is
2448 lib/silcclient/command.c.
2450 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Fixed a fatal bug in private message sending and reception
2453 encryption and decryption when using private message keys.
2454 The implementation was incorrect and did not follow the
2455 specification. It causd that some of the message were
2456 lost since it did not use the sending and receiving keys
2457 as the protocol suggests. This has been fixed and will cause
2458 incompatibilities with older clients when sending private
2459 message encrypted with private message keys. Affected files
2460 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2461 and various other in Irssi SILC Client.
2463 Added `responder' boolean argument to the functions
2464 silc_client_add_private_message_key[_ske] to indicate when
2465 the key is added as responder or initiator of the key
2468 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Removed the silc_ske_check_version function and created
2471 a SilcSKECheckVersion callback. Added also a function
2472 silc_ske_set_callbacks that is now used to set all SKE
2473 callbacks. The callback functions are not given to
2474 the SKE functions anymore, but this function is used to
2477 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2479 * Added `silc_version' argument to the silc_client_alloc
2480 to define the version of the application for the library.
2481 The library will use the version string to compare it
2482 against the remote host's (usually a server) version
2483 string. Affected file lib/silcclient/silcapi.h
2485 * Added the KE protocol context to Key Agreement context
2486 in client library so that we can abort the SKE if it
2487 is in process when we get timeout. Affected file is
2488 lib/silcclient/client_keyagr.c.
2490 * Do not resolve the client ID forever if it returns in the
2491 first time that such client does not exist. This was done
2492 for example with private message. Affected file is
2493 lib/silcclient/client_prvmsg.c.
2495 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Do not add regex.h for WIN32. The affected file
2498 includes/silcincludes.h.
2500 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2501 not work yet 100%. It generates the DLL's automatically
2502 when compiling with --with-win32 under cygwin.
2504 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * lib/contrib/regex.c is not compiled on WIN32.
2508 * Added silc_net_get_socket_opt function to the
2509 lib/silcutil/silcnet.h.
2511 * Added includes/silcwin32.h for WIN32 specific includes
2514 * Do not use ptime structure or any of the posix process
2515 functions on WIN32 in lib/silccrypt/silrng.c.
2517 * Added silc_gettimeofday to provide generic function
2518 for struct timeval on all platforms. Added the function
2519 to lib/silcutil/silcutil.h.
2521 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2523 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2524 library as they clearly belong there. As a plus side we
2525 can make the actual socket connection routines platform
2528 Added also new generic function silc_socket_read and
2529 silc_socket_write (that used to be silc_packet_[read/write].
2530 The implementation of these are platform specific.
2532 * Added WIN32 specific routines of silc_socket_[read/write]
2533 to lib/silcutil/win32/silcwin32sockconn.c.
2535 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * Added preliminary support for native WIN32 compilation under
2538 cygwin (using the -mno-cygwin option for GCC) to the
2539 ./configure.in.pre. The --with-win32 now prepares the
2540 compilation for native WIN32.
2542 * Rewrote the SILC Scheduler interface in the file
2543 lib/silcutil/silcschedule.h. The scheduler is now context
2544 based and does not have anymore any global static scheduler.
2545 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2546 and created lib/silcutil/win32 directory for WIN32 based
2549 * Added Unix specific network routines to the
2550 lib/silcutil/unix/silcunixnet.c and the old
2551 lib/silcutil/silcnet.c includes now only generic routines.
2553 Added WIN32 specific network routines to the
2554 lib/silcutil/win32/silcwin32net.c.
2556 * Added Unix specific utility functions from the
2557 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2559 * Added WIN32 SILC Scheduler to the file
2560 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2563 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2565 * Do not handle JOIN notify in the server if the target client
2566 is not registered (idata->registered == FALSE). The affected
2567 file is silcd/packet_receive.c.
2569 * Update the nickrec->founder in event_cumode in the Irssi SILC
2570 client. Affected file irssi/src/silc/core/silc-channels.c.
2572 * Fixed the CUMODE_CHANGE notify handling in the server when
2573 server and router are announcing their clients on channels.
2574 Now the mode changes are saved and notified correctly. The
2575 affected file is /silcd/packet_receive.c.
2577 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2578 They really did not replace the cache entry in the ID Cache.
2579 Now they do that. Affected file silcd/idlist.c.
2581 * Fixed the KICK notify handling in the Irssi SILC client to
2582 update the channel records so that the kicked client does not
2583 appear to be on the channel. The affected file is
2584 irssi/src/silc/core/silc-channels.c.
2586 * Always update the conn->current_channel when executing command
2587 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2589 * Fixed the KILL notify handling in Irssi SILC client to remove
2590 the killed client on all channels.
2592 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * Fixed the silc_parse_command_line to remove extra spaces
2595 from the start and end of the arguments. Affected file is
2596 lib/silcutil/silcutil.c.
2598 * Cancel and free any active protocol in the function
2599 silc_server_close_connection. Affected file silcd/server.c.
2601 * Cancel and free any active protocol in the function
2602 silc_client_close_connction. Affected file is
2603 lib/silcclient/client.c.
2605 * Do not execute the KILL command for clients that are in
2606 history (ie. they are not in the network). Affected file is
2609 * Fixed KILL notify handling, client does not crash anymore.
2610 Affected file irssi/src/silc/core/silc-channels.c.
2612 * Reduced the default packet buffer size from 2048 to 1024 in
2613 lib/silccore/silcpacket.c.
2615 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2616 counter to the SKE context that is incresed when the SKE library
2617 performs async operation outside the library. If the outside
2618 process frees the SKE context and FREED status will be set
2619 and the library will detect after the sync operation that the
2620 libary is freed. The affected files are
2621 lib/silcske/silcske[_status].[ch].
2623 * Resolve the client entry information in the function
2624 silc_client_channel_message to assure that NULL pointer is not
2625 passed as client entry to the application. */
2627 * Fixed the task timeout calculation to assure that there is
2628 never negative timeouts. The affected file is
2629 lib/silcutil/silcschedule.c.
2631 * Fixed the channel user mode notification sending in server.
2632 It was sent point-to-point to the router (or to server by router)
2633 but it needs to be destined to a channel. The routines now
2634 supports sending the channel user mode notifys to the channels
2635 when announcing clients and channels. Affected files are
2636 silcd/server.c and silcd/packet_receive.c.
2638 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2639 It did not actually replace the old channel entry in the cache.
2640 Affected file lib/silcclient/client_notify.c.
2642 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Fixed a possible crash in silc_packet_send_prepare. It now
2645 assures always that there is enough space in the buffer and
2646 at the tail area of the buffer (for MAC).
2648 Fixed the inbound buffer reallocation in silc_packet_read.
2649 It was old code and did not handle the reallocation correctly.
2652 The affected file is lib/silccore/silcpacket.c.
2654 * Fixed buffer overflow in silc_parse_nickname in the file
2655 lib/silcutil/silcutil.c.
2657 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2659 * make install generates new server keys only if there is not
2662 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2665 Added check that if the NOREPLY is set then we will not send
2666 the away message. This avoids infinite loop of away messages
2667 if both clients are away. The affected file is
2668 lib/silcclient/client_prvmsg.c.
2670 * Fixed client crash if /NICK was given without arguments.
2671 Affected file lib/silcclient/command.c.
2673 * Server does not send the invite list in INVITE command back
2674 to the client if the list was not altered. Added this notion
2675 to the protocol spec as well. Affected file silcd/command.c.
2677 Fixed possible crash in INVITE command by checking the
2678 value of silc_server_get_client_route command.
2680 * Fixed the INVITE notify type handling. The arguments are now
2681 taken in correct order and client does not crash. The affected
2682 file is irssi/src/silc/core/silc-channels.c.
2684 Removed the "Inviting xxx to channel" message from the
2685 client library away and let the application handle it.
2686 Affected file lib/silcclient/command.c. Added that message
2687 to Irssi SILC client's message formats.
2689 * Fixed CMODE command crash in client. It now checks the
2690 amount of arguments correctly and does not crash. The affected
2691 file is lib/silcclient/command.c.
2693 * Do not create new channel automatically in silc_channels_join
2694 but check whether the channel by that name already exists.
2695 Affected file irssi/silc/core/silc-channels.c.
2697 * Do not send the SERVER_SIGNOFF to router if the disconnected
2698 entity was the router. Affected file silcd/server.c.
2700 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2701 SILC client as it was missing from there.
2703 Added the handling of the KICK notify to the Irssi SILC client
2704 as it was missing. Added "you have been kicked" message to
2705 Irssi SILC client's message modules formats.
2707 Added the handing of the KILL notify to the Irssi SILC client
2708 as it was missing. Added the kill message module formats
2711 The affected file is irssi/src/silc/core/silc-channels.c.
2713 * The router did not save the channel mode the server announced.
2714 Affected file silcd/packet_receive.c.
2716 * Fixed a possible crash in INFO command in server. If the
2717 server did not provide the server info it crashed. Affected
2718 file silcd/command.c.
2720 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * Fixed the GETKEY command in the server to check also the
2723 global list. Otherwise the GETKEY would not work correctly
2724 in normal SILC server. Affected file silcd/command.c.
2726 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Fixed GETKEY crash, it crashed if the command did not succseed.
2730 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2732 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2733 is now real and not just an macro interface to GMP.
2735 Removed the entire GMP from the source tree and imported new
2736 NSS MPI library instead. Reason for removing GMP is that it is
2737 extremely large and compiles extremely slow. The NSS MPI
2738 is only a few files and compiles in less than 10 seconds.
2739 The speed is also about the same as GMP. The MPI is imported
2740 to lib/silcmath/mpi.
2742 If the system has GMP installed we will still use the GMP.
2743 If it is not then the NSS MPI will be compiled.
2745 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * Merged a long nickname (127 characters long) crash bugfix from
2748 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2750 * Merged a freed memory reference bugfix from Irssi CVS tree.
2751 Affected file irssi/src/core/commands.c.
2753 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2755 * Added the server's public key sving and verification to the
2756 server when performing the SKE. This was missing and the
2757 remote server's (or router's) public key was accepted without
2758 checking whether we have it previously or trust it at all.
2759 Affected file silcd/protocol.c.
2761 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Check in the silc_server_timeout_remote if protocol is active
2764 and make sure that the protocol's final callback is called so
2765 that all memory if freed. Affected file silcd/server.c.
2767 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * silc_server_whois_send_reply crashed the server if the nickname
2770 was 127 characters long. Affected file silcd/command.c.
2772 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Added sanity check to the silc_server_new_client. If the hostname
2775 is provided inside username then check that the provided hostname
2776 really is the same as the resolved one. If the hostname was not
2777 resolved then check it from the public key. Affected file is
2778 silcd/packet_receive.c.
2780 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2781 if the server disconnected us and the connection is not valid
2782 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2784 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2785 the library to the lib/silcutil/silcutil.[ch].
2787 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Close log file after open. Affected file
2790 lib/silcutil/silclog.c.
2792 * Check whether sock == NULL in silc_client_send_packet and return
2793 if it is. Affected file lib/silcclient/silcclient.c.
2795 * Check rec->entry == NULL in the Irssi SILC Client before
2796 sending the channel message. Affecte file is
2797 irssi/src/silc/core/silc-servers.c.
2799 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Merged a splitted window bugfix from Irssi CVS tree. The
2802 affected file is irssi/src/fe-text/textbuffer-view.c.
2804 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2805 It did not print nickname.
2807 * Improved the distributions system a bit.
2809 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2812 irssi/src/fe-text/gui-window.c.
2814 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2815 to in-active server. The affected file is
2816 irssi/src/silc/core/client_ops.c.
2818 * Resolve the client in USERS command reply if the entry does
2819 not have username resolved. The affected file is
2820 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2821 command to WHOIS command to really resolve stuff. The USERS
2822 is not used any more in any critical section so WHOIS can
2823 be used even though it might be slower than IDENTIFY.
2825 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2828 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2830 * Changed the protocol API a bit more consistent in the
2831 lib/silccore/silcprotocol.[ch].
2833 * Changed the following headers to ROBODoc format:
2835 lib/silccore/silcpayload.h
2836 lib/silccore/silcprotocol.h
2837 lib/silccore/silcsockconn.h
2839 All core library headers are now formatted.
2841 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Fixed a bug in Irssi SILC client; do not show that you are
2844 server/router operator if you really are not. Affected file is
2845 irssi/src/silc/core/client_ops.c.
2847 * Renamed silc_command_free_payload to silc_command_payload_free.
2848 Affected file lib/silccore/silccommand.h
2850 * Added silcmath.h to include the prototoypes of various routines
2851 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2854 * Changed the following headers to ROBODoc format:
2856 lib/silccore/silcchannel.h
2857 lib/silccore/silccommand.h
2858 lib/silccore/silcid.h
2859 lib/silccore/silcidcache.h
2860 lib/silccore/silcmode.h
2861 lib/silccore/silcnotify.h
2862 lib/silccore/silcpacket.h
2863 lib/silcmath/silcmath.h
2865 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Added checking to the server code not to start the server if
2868 ciphers and stuff are not configured properly. Affected files
2869 silcd/serverconfig.[h] and silcd/server.c.
2871 * Changed the layout of the header files of the public interfaces
2872 in the SILC libraries. The new layout supports ROBODoc
2873 documentation tool (and some others) so that it is easy to create
2874 a library reference manual. All the other headers and source
2875 code must still follow the CodingStyle document. Also source
2876 code must not include these ROBODoc stuffs, only the headers.
2877 Furthermore, all public interface headers must now be named
2878 by using `silc' prefix, example: silcapi.h, silccipher.h.
2879 Some files were renamed due to this. All the other headers
2880 must not be used as public interfaces. I will update the
2881 CodingStyle document later. Changed following headers, so far:
2883 lib/silcclient/silcapi.h
2884 lib/silccore/silcauth.h
2885 lib/silccore/silcprivate.h
2886 lib/silccrypt/silcdh.h
2888 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Removed silc_client_packet_send_flush from the client library
2893 as it is not needed. Affected file lib/silcclient/client.[ch].
2895 * Added printing of message of unresolved authentication method
2896 to the Irssi SILC client. Added it to the module formats.
2897 Removed the same message from the client library.
2899 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2901 * Added new distribution feature, DISTLABEL. Every distribution
2902 can define own preprocessor label that can be used in the
2903 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2904 file distributions, acconfig.h.pre and prepare.
2906 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Added Makefile.defines_int to include the actual definitions
2909 for Makefile.defines.in. Tested the new distribution system,
2910 created distributions and tested installation.
2912 * Added AWAY message printing to the Irssi SILC client. Added
2913 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2915 * Added SCONNECT command to call the SILC's CONNECT command.
2916 Cannot use CONNECT directly since Irssi uses that internally.
2917 Affected file irssi/src/silc/core/silc-servers.c.
2919 Added ACTION local command. It is same as ME command but takes
2920 the channel as mandatory argument.
2922 Rewrote some of the Irssi's help files to suite for SILC
2925 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2927 * Added Makefile.defines[.in] that should for now on be included
2928 in all Makefile.am file in the source tree. That file includes
2929 all common compilation definitions for SILC source tree.
2931 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * Minor changes to the ./prepare script to change the package
2934 name according the distribution name to the configure.in.
2936 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Created new distribution system. Added file `distributions'
2939 that defines all the distributions that can be created out of
2940 the SILC source tree. The ./prepare script now reads that
2941 file to determine how to prepare the distributions. The
2942 first argument to the ./prepare is the name of the distribution
2943 and second is the version of the distribution. If given
2944 without arguments it creates the default (toolkit) distribution
2945 with the default version (defined in ./prepare).
2947 All Makefile.am files that are subject to the distributions
2948 are now named as Makefile.am.pre. These are ./Makefile.am
2949 and lib/Makefile.am. Others may be changed later.
2951 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Added invite list, ban list, some key management and connection
2954 error message printing to module formats in the Irssi SILC client.
2956 * Added new silc_client_set_away_message to set the away message
2957 that is back to the person who sent private message. The
2958 affected file lib/silcclient/silcapi.h and the
2959 lib/silcclient/client_prvmsg.c.
2961 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Fixed the private message sending in the Irssi SILC client,
2964 added local command KEY to the Irssi SILC client.
2966 Added key management and key agreement message formats to the
2967 irssi/src/fe-common/silc/module-formats.[ch].
2969 Added USERS (alias WHO) printing, server/router operator
2970 indication and LIST command printing to the module formats.
2972 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Fixed channel joining notify handling, cumode notify handling
2975 from Irssi SILC client.
2977 * Added SILC specific module-formats to the Irssi SILC client so
2978 that SILC specific message hilighting, colors etc is possible.
2979 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2981 Added channel mode, channel user mode, actions, notices,
2982 whois and whowas printing to the the module-formats.c.
2984 * Fixed a bug in channel deletion in the server. The channel
2985 is not left to the cache even if the channel founder auth mode
2986 is set when there are no users anymore on the channel. Affected
2987 file silcd/server.c.
2989 * The silc_net_localhost now resolves the entire hostname including
2990 the domain name. Affected file lib/silcutil/silcnet.c.
2992 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Changed the ask_passphrase client operation to be ascynchronous.
2995 It has now a completion callback and a context that the
2996 application must call after it has got the passphrase from
2997 the user. Affected files lib/silcclient/silcapi.h,
2998 lib/silcclient/protocol.c, lib/silcclient/command.c and
3001 Added SilcAskPassphrase callback that the application calls
3002 to deliver the passphrase to the library.
3004 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3005 The public key verification and especially a certificate
3006 verification is asynchronous procedure.
3008 Added new SILC_SKE_STATUS_PENDING status to indicate the
3009 request is pending and a callback will be called to finalize
3012 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3013 indicate that remote end did not send its public key (or
3014 certificate), even though we require it. Added check for this
3015 condition in the SKE. This was a security bug, now fixed.
3017 Defined new SilcSKEVerifyCbCompletion callback that is called
3018 when the verification process is completed.
3020 The affected files lib/silcske/silcske_status.h and
3021 lib/silcske/silcske.[ch].
3023 * Changed the verify_public_key client operation to be async
3024 as well. Defined SilcVerifyPublicKey callback that is used to
3025 indicate the success of the public key verification process.
3027 Changed the server and client to use the new async client
3030 * Changed the Irssi SILC client's internal scheduler to be called
3031 twice as many times as it used to be. As a result the client
3032 should be a bit faster now. Affected file is
3033 irssi/src/silc/core/silc-core.c.
3035 * Added support to Irssi SILC client of asynchronous public key
3036 verification and passphrase inquiry. Affected file is
3037 irssi/src/silc/core/silc-core.c.
3039 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Do not say "You have left channel %s" in client library.
3042 Moved it to the application. Affected files are
3043 lib/silcclient/command.c and silc/client_ops.c.
3045 * Fixed silc_client_get_clients. Command context was not
3046 duplicated and was freed memory in the callback. Affected
3047 file lib/silcclient/idlist.c.
3049 * Do not say "you are now talking..." on JOIN command in the
3050 client library. The appliation must handle it.
3052 * Do not say ".. changed topic to" in command reply in the
3053 client libary. The application must handle it.
3055 * Fixed TOPIC command sending in the client library.
3057 * Fixed a memory leak in silc_client_command_free in the file
3058 lib/silcclient/command.c.
3060 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Imported a modified version of Irssi client to the source tree.
3063 The Irssi will be used to create a new client called
3064 Irssi SILC. Imported to irssi/.
3066 Added silc_core_init_finish function to the Irssi. Affected
3067 file irssi/configure.in.
3069 A lot changes in the Makefile.ams around the irssi tree.
3071 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3073 * Do not rehash if the new size is same as the old size of the
3074 hash table, in the silc_hash_table_rehash*. The affected file
3075 lib/silcutil/silchashtable.c.
3077 * Replaced hash_table_del_by_context calls from the server
3078 (when channel->user_list and client->channels) to the
3079 hash_table_del as it is sufficient and faster.
3081 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Added silc_hash_table_list, silc_hash_table_get and the
3084 SilcHashTableList structure to provide an alternative way to
3085 traverse the hash table. The affected files are
3086 lib/silcutil/silchashtable.[ch].
3088 * Changed the server's idlist routines to use the hash table
3089 routines to optimize the code.
3091 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Replaced the client entry's `channel' list and channel entry's
3094 `user_list' list to hash tables for optimized lookup. Changed
3095 the code to use the hash table interface around the code.
3096 Affected file lib/silcd/idlist.[ch].
3098 * Added `auto_rehash' boolean argument to the function
3099 silc_hash_table_alloc to indicate whether the hash table should
3100 auto-rehash when it thinks is appropriate time. It will
3101 increase the hash table size if the there is twice as much
3102 entries in the table than the size of the table, and will
3103 decrease the size if there are twice as less entries than
3104 the size of the table.
3106 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3110 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * silc_idcache_purge_by_context deletes the entry now by context
3113 as it is supposed to do. Affected file lib/silccore/idcache.c.
3115 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3116 client is not anymore valid (WHOWAS givens the info) and not
3117 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3119 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Removed the `data' and `data_len' arguments from the ID Cache
3122 interfaces and added `name' argument. ID Cache does not handle
3123 anymore the binary data only a names associated with given ID.
3125 * When hashing a Client ID with silc_hash_id the entire ID is
3126 not hashed anymore, instead only the hash of the Client ID is
3127 hashed. This way we can access the Client ID from the cache
3128 with Client ID but with the hash of the ID (which is a hash of
3129 the nickname) as well without any difference in performance.
3131 Added also silc_idcache_find_by_id_one_ext to do one on one
3132 searching when we have the actual ID. Added also function
3133 silc_hash_client_id_compare. The affected files are
3134 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3136 * When hashing the name associated with a ID it is always done
3137 in lowercase. This way we can access the cache without worrying
3138 about case-sensitivity, even though, for example nicknames are
3141 * Fixed a bug in server with channel message sending. It put
3142 wrong ID type as destination ID. The affected file
3143 silcd/packet_send.c.
3145 * silc_idcache_del_by_context now deletes from all hash tables
3146 by context. Affected file lib/silccore/idcache.c.
3148 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3150 * Changed the client library to use the new ID Cache interface.
3151 Changes around the source tree.
3153 * Added silc_hash_table_rehash_ext to rehash with specific
3154 hash function. Affected file lib/silcutil/silchashtable.[ch].
3156 * Added silc_hash_string_compare to compare two strings in the
3157 hash table. Affected file lib/silcutil/silcutil.[ch].
3159 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Added new function silc_idcache_del_by_context into the
3162 lib/silccore/idcache.[ch].
3164 * Changed the server's ID list routines to use the new ID Cache
3165 interface. Changes around the source tree.
3167 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Added silc_hash_table_del[_by_context]_ext functions in to the
3170 lib/silcutil/silchashtable.[ch].
3172 Removed silc_hash_table_find_all* routines and added new
3173 silc_hash_table_find_foreach to replace them.
3175 Added silc_hash_table_replace_ext function as extended
3176 replacing function. Separated the simple hash table interface
3177 from the extended hash table interface in the file
3178 lib/silcutil/silchashtable.h.
3180 * Fixed minor bugs and changed it to use some of the new
3181 hash table functions in lib/silccore/idcache.c
3183 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3185 * Added new function silc_hash_table_find_all to return all keys
3186 in the hash table by the specified key. As the hash table is
3187 collision resistant it also makes it possible to have several
3188 duplicate keys in the hash table. This function may be used to
3189 find all of the keys from the hash.
3191 Added user_context arguments to the SilcHashFunction,
3192 SilcHashCompare and SilcHashDestructor to deliver user specified
3195 Added new fuctions silc_hash_table_find[_all]_ext to do
3196 extended lookup with specified hash and compare functions and
3197 specified user contexts.
3199 Added new function silc_hash_table_add_ext to add the key
3200 with specified hash function and user context.
3202 Added new function silc_hash_table_foreach to traverse all
3203 entrys in the hash table. Added SilcHashForeach callback
3206 Added new function silc_hash_table_del_by_context to delete
3207 the entry only if the context associated with the key matches.
3209 Affected files are lib/silcutil/silchashtable.[ch].
3211 * Removed silc_hash_[server/client/channel]_id and added just
3212 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3213 silc_hash_id_compare to compare two ID's using as the hash table
3214 comparison function. Added also silc_hash_data to hash
3215 binary data and silc_hash_data_compare to compare it.
3217 * Removed silc_idlist_find_client_by_hash as it is not needed
3218 anymore. Affected file silcd/idlist.[ch].
3220 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3221 to use internally the SilcHashTable. The new ID Cache is a lot
3222 faster than the old one. Some of the ID Cache interface was also
3223 rewritten and obsolete and stupid functions were removed.
3225 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Added entry_count field to the SilcHashTable to keep the number
3228 of the entries in the table. Implemented the function
3229 silc_hash_table_rehash. Added new function
3230 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3232 Fixed a minor bug in silc_hash_table_free.
3234 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3235 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3236 into the lib/silcutil/silcutil.[ch].
3238 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Implemented a collision resistant hash table into the
3241 lib/silcutil/silchashtable[ch]. See the header and the source
3242 for the SilcHashTable API.
3244 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Merged dotconf version 1.0.2 into lib/dotconf.
3248 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3250 * Do not compile anything in lib/silcsim/* if the SIM support
3251 is not enabled. The tree should now compile without problems
3254 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Compiled the SILC under cygwin. Compiled and tested briefly
3257 without problems. More tests needed. The SIMs didn't compile
3260 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3262 * Fixed possible crash in silc_get_username in the
3263 lib/silcutil/silcutil.c.
3265 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Fixed a va_arg in silc/client_ops.c.
3269 * Oops, RC5 routines were named AES and caused some problems
3270 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3272 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3274 * Added new SilcIDIP structure into the lib/silccore/id.h and
3275 replaced the old `ip' fields from all SILC ID's to that type.
3276 This is a step towards IPv6 support.
3278 The silc_id_get_len takes now the ID as an extra argument.
3279 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3280 both IPv4 and IPv6 based ID's.
3282 The affected files are lib/silccore/id.[ch] and other files
3283 around the tree using these routines.
3285 * Removed the ID length arguments in server from various
3286 silc_server_send_notify_* routines -> they are not needed
3289 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Fixed memory leak in silc_encode_pem_file in the file
3292 lib/silcutil/silcutil.c.
3294 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * Check minor version as well in the SKE. Affected files are
3297 silcd/protocol.c and lib/silcclient/protocol.c.
3299 * Added --identifier option to the server so that an identifier
3300 can be when creating the public key for the server. Affected
3301 file is silcd/silcd.c.
3303 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3304 lib/silccrypt/silcpkcs.c.
3306 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3308 * Register default ciphers and stuff when using -C option with
3309 the server. Affected file sildc/silcd.c.
3311 * Put back the servers public key filename format, it is better
3312 than the new one. For now, the client keys are saved with the
3313 new filename format. The affected file silc/client_ops.c.
3315 * Implemented the Cipher API for the rest of the ciphers that
3316 did not implement it or implemented it the wrong way.
3318 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Register default ciphers and stuff when using the -S option
3321 in the client. Affected file silc/silc.c. Same also when
3322 creating new key pair with -C option.
3324 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Fixed the silc_verify_public_key client operation function to
3327 save the public keys differently. The fingerprint is now
3328 used as filename and not the hostname. This way also the
3329 client keys are saved uniquely and not with hostnames. The
3330 affected file is silc/client_ops.c.
3332 * Trimmed the silc_hash_fingerprint function to remove extra
3333 whitespaces from the end of the fingerprint. The affected
3334 file is lib/silccrypt/silchash.c.
3338 * Added silc_cipher_register_default function to register all
3339 default ciphers. It can be used when configuration files
3340 does not exist and the application does not want any specific
3341 ciphers in any specific order.
3343 The SilcDList is now used as silc_cipher_list dynamically
3344 allocated cipher list. Removed the static list all together
3345 and now all ciphers must be allocated to the dynamic list.
3346 The silc_cipher_alloc routine was changed to check only the
3349 All silc_cipher_* routines that used to return int returns
3352 The affected files lib/silccrypt/silccrypt.[ch].
3354 * The same thing was done to silc_hash_* as for silc_cipher_*
3355 routines. Affected files lib/silccrypt/silchash.[ch].
3357 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3358 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3359 Added also silc_pkcs_[un]register[_default] functions.
3360 Removed the data_context from the PKCS API.
3362 * Added silc_hmac_register_default function to register default
3363 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3364 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3365 to unregister all hmacs at once.
3367 * Register the default ciphers, hash functions, PKCSs and HMACs
3368 if client's configuration file does not exist. The affected
3371 * The client did not load the hash functions from the SIM
3372 modules at all. Added support for this. Affected file is
3373 silc/clientconfig.c.
3375 * When decoding public key with silc_pkcs_public_key_decode, check
3376 the supported algorithm only if PKCS are registered. Affected
3377 file lib/silccrypt/silcpkcs.c. The same was done with the
3378 silc_pkcs_private_key_decode.
3380 * Fixed the SILC List routines to keep the list always in order.
3381 It used to change the list's order when traversing the list but
3382 not it preserves the order. Affected file lib/trq/silclist.h.
3384 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3386 * Added the client library to use the SilcSocketConnection's
3387 reference counter (by silc_socket_dup) to prevent the bug that
3388 the socket object may be freed underneath async operation.
3390 * The name resolv library checking fixes in the configure.in.pre.
3393 * Created new version of the protocol drafts for future
3394 development. The -03 drafts are the ones that will be changed
3395 in the trunk now and the -02 will remain as they are.
3397 * Send list of CUMODE notifys to the router when announcing
3398 the channel users to the router. Affected file silcd/server.c.
3399 If the router receiving channel founder CUMODE for a channel
3400 that already has channel founder it will send CUMODE notify
3401 to the sender to remove the channel founder rights from the
3402 announced client. Affected file silcd/packet_receive.c.
3404 * The CUMODE notify may now use Server ID as well as the entity
3405 who changes the mode. Updated protocool specs.
3407 * Updated INSTALL and README files.
3409 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * New web pages in the http://silc.pspt.fi. The pages was
3416 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3418 * Implemented the [DenyConnectin] config section in the server.
3419 Added silc_server_config_denied_conn to check whether incoming
3420 connection is denied. Affected file silcd/serverconfig.[ch].
3422 * Do not check the ports when checking the incoming configuration
3423 data if the port is 0, meaning any. Affected file is
3424 silcd/serverconfig.c.
3426 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3428 * Fixed buffer overflow in silc_string_compare in the file
3429 lib/silcutil/silcutil.c.
3431 * Fixed double free in silc_server_command_leave in the file
3434 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Fixed the version checking in the server. Affected file is
3439 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3441 * Fixed the configuration data fetching when accepting new
3442 connections in the server. Affected file silcd/server.c.
3444 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Added `sender_entry' argument to the function
3447 silc_server_packet_relay_to_channel so that we can check
3448 whether some destination actually belongs to the same route
3449 the sender belongs (ie, we must not resend the packet to the
3450 sender). Affected file silcd/packet_send.[ch].
3452 * Added `servername' field to the SilcClientEntry in the server
3453 to hold the name of the server where client is from. Affected
3454 file is silcd/idlist.h.
3456 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Moved the channel message encrypting in the router betwen
3459 router connections from silc_server_channel_message to the
3460 silc_server_packet_relay_to_channel since we want to check
3461 whether we have anybody channel before encrypting anything.
3462 Affected files silcd/packet_[receive/send].c.
3464 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * Fixed the [AdminConnection] server config section to support
3467 multiple entries. Affected file silcd/serverconfig.c.
3469 * Added support into the server to check the validity of the
3470 incoming connection before executing any KE or authentication
3473 * The connection configuration is now saved to the KE and
3474 connection auth protocol contexts and not fetched anymore in
3475 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3477 * The local hosts listenning address and port is also resolved
3478 now when starting the server. We want to have the socket object
3479 to include the real address and port for the listener. Added
3480 new function silc_net_check_local_by_sock into the files
3481 lib/silcutil/silcnet.[ch].
3483 * Fixed a broadcast bug in server -> do not broadcast if we
3486 * Fixed a routing bug. Do not route broadcast packets ever.
3487 Broadcast packets must be processed always and not routed since
3488 they may be destined to some other host than yourself and thus
3489 would get routed without no good reason. Affected file is
3492 * Added function silc_server_config_is_primary_route to check
3493 whether primary router connection has been configured (a router
3494 configuration that we are initiating). If there is not, we
3495 will assume that there is only two routers in the SILC network
3496 and we will use the incoming router connection as our primary
3497 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3499 * Changed the order of the broadcasting. Broadcast _after_ the
3500 packet has been processed not before. Affected file is
3503 * Fixed a [ClientConnection] parsing bug. The port was never
3504 parsed correctly thus resulting to port 0. Affected file
3505 silcd/serverconfig.c.
3507 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3508 argument and did not set the broadcast packet flag. Affected
3509 file silcd/packet_send.c. Fixed same bug in the function
3510 silc_server_send_notify as well.
3512 * If we receive NEW_ID packet for our own ID in the server, ignore
3515 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Removed the nickname from the Private Message Payload.
3520 Updated the code and the protocol specs.
3522 * Updated protocol specs for submitting to the IETF.
3524 * Tweaked the Random Number Generator a bit. Affected file
3525 lib/silccrypt/silcrng.c. Exported a new function
3526 silc_rng_[global]_add_noise which can be used to add more
3529 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Do not parse packets with different timeout when protocol
3532 is active -> may cause problem with rekey. Affected file
3535 * When server receives signoff notify it must not create
3536 new channel key if the client is on any channels since the
3537 sender of the signoff notify will create it.
3539 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3541 * Added printing of error messages during SKE protocol from the
3542 failure packet sent by server during SKE. Affected file
3545 * Removed the client's failure_callback handling with timeout
3546 and handle it immediately when received.
3548 * The SKE library returned wrong type in SUCCESS and FAILURE
3549 packets. They must be 32 bit MSB not 16 bit MSB.
3551 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3553 * Ok, rewrote the logic of the re-key and now it seems to work.
3554 I tested it on high traffic with frequent re-keys without
3555 problems. Added hmac_receive (and renamed hmac to hmac_send)
3556 in SilcClientConnection in lib/silcclient/client.h and
3557 in SilcIDListData in silcd/idlist.h. Also, removed the
3558 SilcPacketParserContext's cipher and hmac fields as they are
3559 not needed anymore and actually caused some problems when
3560 the ciphers and hmac's changed underneath the packet parser.
3562 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * If re-key protocol is active then process the incoming packets
3565 synchronously since we must assure that icoming packets encrypted
3566 with the old key is processed before the new keys is set to
3567 use. This is true other packets than for REKEY packets.
3568 Affected file silcd/server.c. The same was done to client library
3569 as well, affected file lib/silcclient/client.c.
3571 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3573 * Fixed bug in client and server to accept the force send if
3574 the packet is send from silc_[server/client]_packet_process
3575 function. Otherwise the packets are never delivered, oops.
3577 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Disable force sending of packets when REKEY protocol is active.
3580 We must assure that no packet is sent directly when rekey is
3581 performed. All packets must be sent through packet queue.
3582 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3583 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3584 function is silc_[server/client]_packet_send_real to check
3587 * Replaced the SIM paths from example config files to
3588 /usr/local/modules. Also, make install creates now
3589 /usr/local/silc/logs directory to hold all the SILC server
3592 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Made the configure.in.pre work on Solaris. Patch by salo.
3596 * Made all ciphers compatible with non-x86 machines. Defined
3597 CBC mode macros into lib/silccrypt/ciphers_def.h.
3599 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Fixed the make install.
3603 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * When MAC computation fails the silc_packet_decrypt returned 0
3606 even though it was supposed to return -1. Fixed this. The
3607 affected file is lib/silccore/silcpacket.c.
3609 * Do not replace the config files in /etc/silc (in make install)
3610 if they already exist. Affected file ./Makefile.am.
3612 * Do not send re-key packets immediately but through packet queue.
3613 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3615 * Changed silc_net_check_host_by_sock to return FALSE if the
3616 IP/DNS could not be resolved. Though, it returns the IP address
3617 now even if it could not resolve it (but returns also FALSE).
3618 Affected file lib/silcutil/silcnet.[ch].
3620 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Added silc_pkcs_decode_identifier to decode the public key's
3623 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3624 Added also silc_pkcs_free_identifier. Added also new context
3625 SilcPublicKeyIdentifier.
3627 * Added -S option to the silc client. It is used to dump the
3628 contents of the specified public key file.
3630 * Changed the PKCS api to return the public key length when
3631 setting the public key.
3633 * Fixed a fatal bug in the public and private key file loading.
3634 Affected file lib/silccrypt/silcpkcs.c.
3636 * Execute the packet parsing for client with zero (0) timeout
3637 if the protocol is active. Affected file silcd/server.c.
3639 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * Made the key generation options to the silcd program. Added
3642 -C option, equivalent to client's option.
3644 * Added new [ServerKeys] config section to the server. It
3645 configures the server's public and private key.
3647 * Defined generic Public Key Payload into the protocol
3648 specification to send specific type of public keys and
3651 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3652 public key or certificate.
3654 * Implemented the GETKEY command to the server and to the
3655 client library and on user interface.
3657 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Made preliminary `make install' work.
3661 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Added SilcServerRekey context into silcd/idlist.h.
3665 * Added the PFS support as defined in the specification to the
3666 SKE protocol. Affected files lib/silcske/*.c.

3669 the number of the SKE group that is used with PFS in re-key.
3670 Affected file silcd/idlist.h.
3672 * Added PFS re-key support to the server. Affected file is
3675 * Added silc_protocol_cancel to cancel execution of the next
3676 state of the protocol. Affected file is
3677 lib/silccore/silcprotocol.[ch].
3679 * Added the re-key support with and without PFS to the client
3680 library. Re-key is performed once in an hour, by default.
3682 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3683 Added silc_client_rekey_callback and silc_client_rekey_final.
3684 Affected files are lib/silcclient/protocol.[ch] and
3685 lib/silcclient/client.[ch].
3687 * Removed the `hmac_key' and `hmac_key_len' fields from the
3688 SilcClientConnection structure; not needed. Affected file is
3689 lib/silcclient/client.h.
3693 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Do not ask whether user wants to use the negotiated private key
3696 for private messages, just use it. Affected file is
3697 silc/local_command.c.
3699 * Added `send_enc_key' and `enc_key_len' fields to the
3700 SilcIDListData structure since they are needed in the re-key
3701 phase. Affected file is silcd/idlist.[ch].
3703 * Implemented the simple re-key protocol into the server.

3714 * Adde `pfs' field to the SilcIDListData to indicate whether
3715 the PFS is to be performed in the re-key. Affected file is
3718 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3721 int64 of at least the xintXX size. If void * is less that 4
3722 bytes uint32 * will be used. Defined bool as boolean.
3724 * Changed _ALL_ unsigned long and unsigned int to uint32,
3725 unsgined short to uint16 in the source tree.
3727 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3728 not handle clients that has entry->data.registered == FALSE.
3729 They are not in the network anymore. Affected file is
3732 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Implemented the sending of the SERVER_SIGNOFF notify in the
3735 server. Affected file is silcd/server.c.
3737 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3738 Added also silc_notify_payload_encode_args into the
3739 lib/silccore/silcnotify.[ch].
3741 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3742 Affected file silcd/packet_receive.c.
3744 * Implemented the SERVER_SIGNOFF notify handling in the client
3745 library. Affected file lib/silcclient/client_notify.c. Also,
3746 implemnted the printing of the SERVER_SIGNOFF info to the
3747 application. Affected file silc/client_ops.c.
3749 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3750 if the deleting was successful. Affected file silcd/idlist.[ch].
3752 * Added support for public key authentication in the connection
3753 authentication protocol in the client library. Affected file
3754 lib/silcclient/protocol.c.
3756 * Changed the server's silc_idlist_get_clients_by_* interface
3757 to support already allocated array so that new entries may be
3758 added to pre-allocated array. Affected file silcd/idlist.[ch].
3759 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3760 and command replies.
3762 * All command reply functions in the server now calls the
3763 pending command callback even if error occured. This way the
3764 error will be delivered to the client as well. Affected files
3765 silcd/command.c and silcd/command_reply.c.
3767 * Fixed INFO command to return local server's info if no server
3768 was provided. Affected file lib/silcclient/command.c.
3770 * Removed RESTART command for good. Updated the code and the
3773 * Rewrote parts of the task system. It is a bit simpler now.
3774 Removed unsued task priorities. The affected files are
3775 lib/silcutil/silctask.[ch].
3777 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Moved the USERS printing from the library to the application.
3780 Affected files lib/silcclient/command.c and silc/client_ops.c.
3782 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * Added channel key re-key support. The re-key is perfomed
3787 only by the router and is done once in an hour. Added `rekey'
3788 field to the SilcChannelEntry in the server. Affected files
3789 silcd/server.c and silcd/idlist.h.
3791 * Added silc_task_unregister_by_context into the file
3792 lib/silcutil/silctask.[ch].
3794 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Added SILC_UMODE_GONE mode to indicate when the client is not
3797 present in the SILC network. Added also support to the local
3798 command AWAY that will set this mode. Added support of showing
3799 "xxx is gone" in WHOIS command. The USERS command shows the
3800 gone status as well.
3802 * Fixed setting server and router operator privileges in the
3803 server's UMODE command. Affected file silcd/command.c.
3805 * Merged the SKE KE1 and KE2 payloads into one payload. The
3806 new KE payload is equivalent to the old KE2 payload.
3808 Cleaned up the SKE Start Payload parsing. It now uses the
3809 simple buffer unformatting to do the parsing. A lot faster
3812 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3813 to the SKE that is used to indicate whether both of the SKE
3814 parties should perform authentication. By default only the
3815 responder performs authentication. By setting this flag also
3816 the initiator must do authentication. By default it is unset
3817 since in normal SKE case, client to server connection, only
3818 the responder should do authentication. When doing SKE between
3819 two clients both should perform authentication. Updated the
3820 code and the protocol specs.
3822 * A little fix to IDENTIFY command in the server. Search the
3823 client first by hash not nickname. Affected file is
3826 * Fixed the silc_client_close_connection to support closing
3827 the client to client connections wihtout deleting too much
3828 data. Affected file lib/silcclient/client.c.
3830 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3831 are received if protocol used to be active but is not anymore
3832 the application would crash due to NULL pointer dereference.
3833 Affected files silcd/server.c and lib/silcclient/client.c.
3835 * Added `hash' field to the SilcClientConnection to include
3836 the hash function negotiated in the SKE protocol.
3838 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3839 to set the channel founder authentication data. A client can
3840 claim the founder rights later by providing the authentication
3841 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3842 This way the channel founder can regain the channel founder
3843 privileges even it is left the channel. This works only on
3844 local server and the client must be connected to the same
3845 server to be able to regain the founder rights. Updated the
3846 protocol specs accordingly.
3848 Added support to the CMODE command in the client to set the
3849 founder auth data. Read the README to see how to set it.
3851 Added support to the CUMODE command to claim the founder
3852 rights. Read the README to see how to do it.
3854 Added support for the founder authentication to the Channel
3855 Entry in the server. Affected file silcd/idlist.h.
3857 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3858 server's CMODE command. Affected file silcd/command.c.
3860 * Added the following new functions into lib/silccore/silcauth.[ch]:
3861 silc_auth_get_method and silc_auth_get_data.
3863 * The server now saves the remote hosts public key to the
3864 SilcIDListData pointer. Affected file silcd/protocol.c.
3866 * The normal server now does not remove the channel entry from
3867 the cache if the founder authentication data is set. It used
3868 to remove it if the founder was the last one on the channel on
3869 the server and left the channel. The auth data is saved and
3870 if the channel is re-joined later the old entry is used with
3871 the old auth data. Affected files silcd/command_reply.c and
3874 * Removed the `pkcs' field from the SilcIDListData structure
3875 in the server; it is not used. Affected file silcd/idlist.h.
3877 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3879 * Fixed packet processing on slow links. Partial packets were
3880 never re-processed because the incoming data buffer was cleared
3881 by the application. Application must not directly clear the
3882 sock->inbuf, the packet processing routines handle it. Fixed
3883 this in client library and in server.
3885 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Fixed the WHOIS and IDENTIFY send reply function to really
3888 check whether to send list or just one entry. Affected file
3891 * Cleaned up the LEAVE command's channel key distribution. The
3892 affected file silcd/command.c.
3894 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3895 can enforce the channel mode as well. In that case the ID
3896 includes the ID of the server. The code now enforces the
3897 mode change if the router have different mode than the server.
3899 * The notify client operation with CMODE_CHANGE notify can now
3900 return NULL client_entry pointer if the CMODE was not changed
3901 by client. Application must check for this.
3903 * Added <Server ID> argument to INFO command to support server
3904 info fetching by Server ID.
3906 * Added silc_server_announce_get_channel_users to get assembled
3907 packets of channel users of the specified channel. Affected
3908 file silcd/server.[ch].
3910 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3911 was freed underneath the ID Cache.
3913 * Re-announce clients when the server received CHANNEL_CHANGE
3914 notify from the router. Affected file silcd/packet_send.c.
3916 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3919 crashed since it did not handle the fact that there is no cipher
3920 called "3" and didn't check the error condition. Now fixed.
3922 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3923 flag. It can be used to send message requests.
3925 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Implemented the RESTART command in the client.
3929 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3930 notice type messages. Added notice printing to the user
3933 * The channel keys are not re-generated if the channel's mode
3934 is PRIVKEY, ie private key on the channel exists. Affected
3935 files silcd/server.c and silcd/command.c.
3937 * Fixed a little bug in channel message delivery when channel
3938 private keys are set in the server. Affected file is
3939 silcd/packet_send.c.
3941 * Changed the setting on channel->on_channel = TRUE from the
3942 silc_client_save_channel_key to the JOIN command reply. The
3943 key payload is not received if the private channel key is set.
3944 Affected file lib/silcclient/command_reply.c and the
3945 lib/silcclient/client_channel.c.
3947 * When the CMODE_CHANGE notify is sent and the channel private
3948 key mode is removed the channel key must be re-generated in
3949 other cells as well. Added this support for the router in the
3950 silcd/packet_receive.c.
3952 * Added new local command NOTICE to send notice message on
3953 channel. Affected file silc/local_command.[ch].
3955 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Added new local command ME to the client. It is used to send
3958 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3959 some action. Affected file silc/local_command.[ch].
3961 * Changed channel_message and private_message client operations
3962 to deliver the message flags to the application. Added also
3963 the `flags' arguments to the silc_client_send_channel_message
3964 and silc_client_send_private_message functions. Affected file
3967 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Redefined the Private Message Payload to support private message
3970 keys and to support the new private message flags. Updated
3971 the protocol specs. Flags makes it possible to have for example
3972 CTCP style messages.
3974 * Added new type SilcPrivateMessagePayload and defined an API
3975 for it in the lib/silcclient/silcprivate.[ch].
3977 * Tested private message private keys successfully. Tested the
3978 private message key set, unset and list commands with the new
3981 * Redefined the Channel Message Payload to include the channel
3982 message flags (equal with private message flags) to support
3983 for example CTCP style messages.
3985 * Defined some of the message (for channel and private message)
3986 flags. Updated the protocol specs and added the flags to the
3987 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3989 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Added SilcKeyAgreementStatus type to the key agreement routines
3992 to indicate the current status and error if one occured.
3993 The status types are defined in the lib/silcclient/silcapi.h.
3995 * Added new local command KEY that is used to set and unset private
3996 keys for channels, set and unset private keys for private messages
3997 with remote clients and to send key agreement requests and
3998 negotiate the key agreement protocol with remote client. The
3999 key agreement is supported only to negotiate private message keys,
4000 it currently cannot be used to negotiate private keys for channels,
4001 as it is not convenient for that purpose.
4003 * Fixed a minor pending callback setting bug in the function
4004 silc_client_get_client_by_id_resolve, now the function works.
4005 Affected file lib/silcclient/idlist.c.
4007 * Added function silc_net_get_local_port to get local bound
4008 port by socket. Added to lib/silcutil/silcnet.[ch].
4010 * Added `sockets' and `sockets_count' fields to the SilcClient
4011 object. They hold the sockets of the listenning sockets in
4012 the client. Listenning sockets may be for example the key
4013 agreement server. Affected file lib/silcclient/client.[ch].
4014 Added functions the silc_client_add_socket and the
4015 silc_client_del_socket. They are exported to the application
4018 * Added ~./silc/clientkeys to support other client's public keys.
4020 * Renamed verify_server_key client operation to verify_public_key
4021 and added one argument to indicate the type of the connection
4022 (server, client etc.).
4024 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Added silc_server_connection_auth_request to handle the
4027 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4028 silcd/packet_receive.[ch].
4030 * Added silc_server_send_connection_auth_request into the
4031 silcd/packet_send.c to send the connection auth request packet.
4033 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4036 * Fixed the public key authentication in responder side in the
4037 server. The `auth_data' pointer includes the SilcPublicKey
4038 not the path to the public key. Affected file silcd/protocol.c.
4040 * Implemented the public key authentication in the initiator side
4041 in the server. Affected file silcd/protocol.c.
4043 * Removed the [RedirectClient] config section from the server
4044 configuration. Is not needed and I don't want to implement it.
4046 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Cleaned up the CMODE command in the server. It now works
4049 correctly and supports all the modes defined in the protocol.
4050 Affected file is silcd/command.c.
4052 * Added `hmac_name' field to the SilcChannelEntry in the server
4053 to hold the default HMAC of the channel. It can be set when
4054 creating the channel (with JOIN command). Affected files
4057 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4058 type to indicate the change of the current cipher and hmac
4059 on the channel. Client can safely ignore the <cipher> argument
4060 (if it chooses to do so) since the CHANNEL_KEY packet will
4061 force the channel key change anyway. The <hmac> argument is
4062 important since the client is responsible of setting the new
4063 HMAC and the hmac key into use.
4065 * Fixed the CMODE command in the client library as well.
4067 * Tested CMODE command in router environment successfully.
4069 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Show the version of the remote client (or server) when connecting
4072 to the server. It is logged to the log file. Affected file
4073 is silcd/protocol.c.
4075 * Fixed the KILLED notify handling in the client library. The
4076 client must be removed from all channels when receiving the
4079 Also, do not remove the client entry when giving the KILL
4080 command but when the KILLED notify is received.
4082 * Removed silc_idlist_find_client_by_nickname from the server.
4083 Not needed anymore. Affected files silcd/idlist.[ch].
4085 * Implemented the CHANNEL_CHANGE notify type handling to the
4086 server. Affected file silcd/server.c.
4090 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * Added silc_server_send_notify_invite to send the INVITE
4093 notify between routers.
4095 * Implemented the INVITE command correctly to the server.
4097 * Implemented the INVITE notify type handling in the server.
4099 * Implemented the INVITE command to the client library and on the
4102 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Added function silc_server_get_client_resolve to find the
4105 client entry by ID from all ID lists and then resolve it
4106 (using WHOIS) if it cannot be found. Affected file is
4109 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Implemented the BAN command to the client library.
4113 * The JOIN command in the server now checks the invite list
4116 * Changed the silc_command_reply_payload_encode_va and the
4117 silc_command_payload_encode_va to support that if argument is
4118 NULL it ignores and checks the next argument. Affected file
4119 lib/silccore/silccommand.c.
4121 * Added silc_server_send_notify_ban to send the BAN notify
4122 type between routers.
4124 * Chaned the silc_notify_payload_encode to support that if
4125 argument is NULL it ignores and checks the next argument.
4126 Affected file lib/silccore/silcnotify.c.
4128 * Tested ban lists in router environment successfully.
4130 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Implemented BAN command to the server, in silcd/command.[ch].
4134 * Removed the BAN and INVITE_LIST modes from the CMODE command
4137 * Added function silc_string_match to regex match two strings.
4138 Affected files lib/silcutil/silcutil.[ch].
4140 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * Redefined parts of the SilcChannelEntry in the server to support
4143 the new ban and invite lists.
4145 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Redefined the INVITE command. The same command can be used to
4148 invite individuals to the channel but also to manage the invite
4149 list of the channel (to add to and remove from the invite list).
4150 Updated the protocol specs.
4152 * Added new command SILC_COMMAND_BAN that can be used to manage
4153 the ban list of the channel. Updated the protocol specs.
4155 * Removed the channel modes: the SILC_CMODE_BAN and the
4156 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4157 in the CMODE command. The equivalent features are now available
4158 using INVITE and BAN commands. Updated the protocol specs.
4160 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4161 in the network about change in the current ban list. The notify
4162 type is not used by the client.
4164 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4165 support the invite lists.
4167 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Added new function silc_string_regexify that converts string
4170 including wildcard characters into regex string that can
4171 be used by the GNU regex library. Added into the file
4172 lib/silcutil/silcutil.[ch].
4174 Added silc_string_regex_combine to combine to regex strings
4175 into one so that they can be used as one regex string by
4176 the GNU regex library. Added into the file
4177 lib/silcutil/silcutil.[ch].
4179 Added silc_string_regex_match to match two strings. It returns
4180 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4182 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Imported GNU regex to the soruce tree into lib/contrib.
4185 Fixed some compiler warning from the regex.c.
4187 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Fixed MOTD command in the server to work in router environment.
4191 * Fixed the MOTD command in the client library to support
4192 the server argument in the command.
4194 * Added `nickname_len' argument to the silc_idlist_add_client
4195 in the server, as the `nickname' argument may be binary data
4198 * Added silc_idlist_get_channels to return all channels from
4201 * Implemented LIST command to the server. Affected file is
4204 * Implemented the LIST command to the client library and on the
4207 * Added [<user count>] argument to the LIST command reply.
4208 With private channels the user count is not shown.
4210 * Updated TODO and README.
4212 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * The client entry's data.registered must be TRUE even with
4215 global client entry on global client list. The data.registered
4216 is used to check whether the client is anymore in the network,
4217 for example with WHOWAS command so it must be valid.
4219 * Fixed the WHOWAS command in the server. It now actually works
4220 in router environment. Added function into silcd/command_reply.c
4221 silc_server_command_reply_whowas_save.
4223 * Added silc_idlist_purge function to the silcd/idlist.c
4224 to periodically purge the ID Cache.
4226 * Fixed INFO command in the server. It works now in router
4227 environment. Added <server name> argument to the INFO command
4228 reply. Updated the protocol specs.
4230 * Fixed minor bug in silc_idcache_purge to not purge if the
4231 expire value is zero.
4233 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4234 they were buggy because of the WHOWAS information.
4236 * Fixed local command MSG to handle the async resolving of
4237 the remote client properly. It used to fail the first MSG.
4238 Affected file silc/local_command.c.
4240 * Added `data_len' field to SilcIDCache context.
4242 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Update TODO. Todo in commands in the server.
4246 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4249 used by routers as broadcast packet to inform other routers
4250 about the changed user mode.
4252 Implemented the notify handling in the server. Affected file is
4253 silcd/packet_receive.c. Added the function
4254 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4256 * Added new generic Channel Payload and deprecated the New Channel
4257 Payload. The New Channel Payload is now the generic Channel
4260 * Added new argument `mode' to the silc_server_send_new_channel
4261 as it is required in the Channel Payload now.
4263 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4264 and created a new and real SilChannelPayload to represent the
4265 new generic Channel Payload. Implemented the encode/decode
4266 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4268 * Added silc_server_get_client_channel_list to return the list
4269 of channels the client has joined for WHOIS command reply.
4270 Affected file silcd/server.[ch].
4272 * Implemented the channel list sending in the WHOIS command reply
4273 in server and in the client.
4275 Implemented the channel list displaying on the user interface
4276 as well. Affected file silc/client_ops.c.
4278 * Added silc_channel_payload_parse_list to parse list of Channel
4279 Payloads. It returns SilcDList list of SilcChannelPayloads.
4280 Client for example can use this function to parse the list of
4281 channels it receives in the WHOIS command reply. The caller
4282 must free the list by calling silc_channel_payload_list_free.
4283 Affected files lib/silccore/silcchannel.[ch].
4285 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Added one new argument <user mode> to the WHOIS command reply
4288 to return the mode of the user in SILC. Updated the protocol
4291 Implemented it to the server and client.
4293 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Fixed the mode printing on the user interface on joining.
4296 Affected file silc/client_ops.c.
4298 * Implemented the UMODE command and user modes in general to the
4299 client library and to the user interface.
4301 * Implemented the UMODE command to the server.
4303 * The server now sends UNKNOWN_COMMAND error status if client sends
4304 unknown command. Affected file silcd/command.c.
4306 * All server commands now handle the command identifier the right
4307 way when sending the command reply to the client. The client can
4308 use to identify the command replies with the identifier.
4310 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Added silc_server_get_client_route to resolve the route to
4313 the client indicated by the client ID. Affected file is
4316 * Added silc_server_relay_packet as general function to relay
4317 packet to arbitrary destination. This deprecates functions
4318 like _send_private_message_key, _relay_notify etc. Affected
4319 file is silcd/packet_send.[ch].
4321 Removed silc_server_send_key_agreement,
4322 silc_server_send_private_message_key and
4323 silc_server_packet_relay_notify functions from the file
4324 silcd/packet_send.[ch].
4328 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4329 server. Affected file silcd/packet_receive.[ch].
4331 * Implemented the KILL command to the client. Implemented the
4332 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4333 Affected files lib/silcclient/command[_reply].c and
4334 lib/silcclient/client_notify.c. Implemented the KILL notify
4335 printing in the user inteface.
4337 * Fixed a lot silc_parse_nick memory leaks from the client
4338 library in the file lib/silcclient/command.c.
4340 * Changed the silc_server_send_notify_on_channels's `sender'
4341 argument from SilcSocketConnection to SilcClientEntry to
4342 check the sender as entry and not as connection object and not
4343 to send to the client provided as argument. The affected file
4344 is silcd/packet_send.[ch].
4346 * The notify packets that are destined directly to the client used
4347 to not to be processed by the server. Now changed that and the
4348 server processes all notify packets. After relaying the packet
4349 to the client the notify packet is processed in the server.
4351 * The silc_server_free_client_data now checks whether there is
4352 pending outgoing traffic for the client and purges the data to
4353 the network before removing the client entry.
4355 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4358 an client is killed from the SILC Network. Updated the protocol
4361 Added new function silc_server_send_notify_killed to the
4362 silcd/packet_send.[ch].
4364 * Added function silc_server_packet_relay_notify to relay notify
4365 packets that are destined directly to a client. In this case
4366 the server does not process the notify packets but merely relays
4367 it to the client. Affected file silcd/packet_send.[ch].
4369 Added also silc_server_packet_process_relay_notify to check
4370 whereto relay the notify. Affected file is
4371 silcd/packet_receive.[ch].
4373 * Implemented the KILL command to the server.
4377 * Added the backup schema desgined last fall to the protocol
4378 specs for everyone to see. The specification is in the
4379 *-spec-xx.txt draft and the packet type definitions for the
4380 backup routers is in *-pp-xx.txt draft. Thusly, added also
4381 new packet type SILC_PACKET_CELL_ROUTERS.
4383 * A big security problem in the implementation discovered. The
4384 signoff of an client did not cause new channel key generation
4385 which it of course should've done. The channel keys must be
4386 always re-generated when client leaves (or signoffs) the channel.
4387 The silc_server_remove_from_channels funtion now handles
4388 the channel key re-generation.
4390 * Added `sender' argument to the silc_server_send_notify_on_channels
4391 to not to send the client provided as argument. Affected file
4392 silcd/packet_send.[ch].
4394 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Implemented OPER and SILCOPER commands into the server and
4399 * Added silc_auth_verify and silc_auth_verify_data to verify
4400 the authentication directly from the authentication payload.
4401 It supports verifying both passphrase and public key based
4402 authentication. Affected file lib/silccore/silcauth.[ch].
4404 * Added `hash' field to the SilcIDListData structure. It is the
4405 hash negotiated in the SKE protocol. Affected file is
4408 * Slight redesigning of the SilcAuthPayload handling routines.
4409 Do not send SilcPKCS but SilcPublicKey as argument.
4411 * Implemented the public key authentication support to the
4412 serverconfig. The public key is loaded from the provided path
4413 and saved as authentication data to void * pointer. Thus,
4414 changed the unsigned char *auth_data to void *auth_data;
4416 * Fixed SHUTDOWN command to send the reply before the server
4417 is shutdown. :) Affected file silcd/command.c.
4419 * Fixed fatal bug in CONNECT command. The hostname was invalid
4420 memory and server crashed. Affected file silcd/command.c.
4422 * Fixed fatal bug in CLOSE command. The server_entry became
4423 invalid but was referenced later in the command. Affected file
4426 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Fixed fatal bug in failure packet handling. Server ignored
4429 the failure and thus crashed when it came.
4433 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4435 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4436 that the command may be executed only once in (about) 2 seconds.
4437 The old SILC_CF_LAG flag is same but allows command bursts up
4438 to five before limiting.
4440 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4441 server code. Various commands now includes the CF_LAG_STRICT
4442 flag to disallow any kind of miss-use of the command.
4444 * Fixed the silc_buffer_unformat to not to allocate any data
4445 if the length of the data is zero. It used to allocate the
4446 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4448 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Changed the format of AdminConnection configuration section
4451 in the server. Added username of the admin to the format.
4452 Affected files silcd/serverconfig.[ch].
4454 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4455 to return admin configuration data by host, username and/or
4458 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Implemented WHOWAS command to the server. Added the functions:
4462 silc_server_command_whowas_parse,
4463 silc_server_command_whowas_send_reply,
4464 silc_server_command_whowas_from_client and
4465 silc_server_command_whowas_from_server
4467 * Added <Client ID> argument to the WHOWAS command reply. Updated
4468 the protocol specs accordingly.
4470 * Implemented WHOWAS command and command_reply to the client
4473 Implemented the WHOWAS printing on the user interface.
4475 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Added new argument to the WHOWAS command reply, the real name.
4478 It is an optional argument. Updated the protocol specs.
4480 * Added SilcIDCacheDestructor callback that is registered when
4481 the SilcIDCache is allocated. The callback is called when
4482 an cache entry in the ID Cache expires, or is purged from the
4483 cache. Added into lib/silccore/idcache.[ch].
4485 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4486 to destruct the client entries when the cache entry expires.
4487 Other ID Cache's in server and in the client library ignores
4490 * If the ID Cache entry's `expire' field is zero then the entry
4491 never expires. Added boolean `expire' argument to the
4492 silc_idcache_add function in the lib/silccore/idcache.[ch].
4493 If it is TRUE the default expiry value is used.
4495 * Added silc_server_free_client_data_timeout that is registered
4496 when client disconnects. By default for 5 minutes we preserve
4497 the client entry for history - for WHOWAS command.
4499 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Added support to the server to enforce that commands are not
4502 executed more than once in 2 seconds. If server receives
4503 commands from client more frequently, timeout is registered
4504 to process the commands. Affected file silcd/command.c.
4505 Added new function silc_server_command_process_timeout.
4507 * Changed NICK_NOTIFY handling in client library to check that
4508 if the client's nickname was changed, so there is no need to
4509 resolve anything from the server.
4511 * Removed error printing from the WHOIS and IDENTIFY commands.
4512 If error occurs then it is ignored silently in the client library.
4513 The application, however, may map the received error to
4514 human readable error string. The application currently maps
4515 the NO_SUCH_NICKNAME error to string.
4517 * Made the command status message public to the application. Moved
4518 them from lib/silcclient/command_reply.c to
4519 lib/silcclient/command_reply.h. The application can map the
4520 received command status to the string with the
4521 silc_client_command_status_message function.
4523 * Added check to the server to check that client's ID is same
4524 as the Source ID in the packet the client sent. They must
4527 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Added dist-bzip hook to the Makefile.am to make bzip2
4530 compressed distributions.
4532 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Server now enforces the maximum length for the nickname and
4535 the channel as protocol specification dictates. 128 bytes for
4536 nickname and 256 bytes for channel name.
4538 * Moved the WHOIS printing to the application. The client libary
4539 does not print out the WHOIS information anymore, the application
4540 must do it. Renamed silc_client_command_reply_whois_print to
4541 the silc_client_command_reply_whois_save.
4543 The client's idle time is also sent to the application now, and
4544 the idle is shown on screen.
4546 * Added silc_client_command_reply_identify_save to save the
4547 received IDENTIFY entries.
4549 * Do not check for channel private keys in message sending and
4550 reception if the channel does not have the PRIVKEY mode set.
4551 Affected file lib/silclient/client_channel.c.
4553 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4556 just surfaced after chaning the JOIN procedure.
4558 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Added silc_client_get_clients_by_list to get client entries
4561 from Client ID list, that is returned for example by JOIN
4562 and USERS command replies. The application should use this
4563 function for example when JOIN command reply is received to
4564 resolve the clients already on the channel (library does not
4565 do that anymore as USERS command reply is not used in the JOIN
4566 procedure anymore). Affected files lib/silcclient/silcapi.h and
4567 lib/silcclient/idlist.c.
4569 * JOIN command reply and USERS command reply returns now SilcBuffer
4570 pointers instead of unsigned char pointers when returning
4571 the client list and mode list.
4573 * Added <Client ID> argument to the JOIN command reply, mainly
4574 for the server to identify for which client the command was
4575 originally sent. Updated protocol specs accordingly.
4577 * Added SilcDlist private_key pointer to the SilcChannelEntry
4578 in the client to support the channel private keys. Affected
4579 file is lib/silcclient/idlist.h.
4581 * Added SilcChannelPrivateKey argument to the function
4582 silc_client_send_channel_message so that application can choose
4583 to use specific private ke if it wants to. If it is not provided,
4584 the normal channel key is used, unless private keys are set.
4585 In this case the first (key that was added first) is used
4586 as the encryption key.
4588 * Implemented the support for channel private key handling.
4589 Implemented the following functions:
4591 silc_client_add_channel_private_key,
4592 silc_client_del_channel_private_keys,
4593 silc_client_del_channel_private_key,
4594 silc_client_list_channel_private_keys and
4595 silc_client_free_channel_private_keys
4597 Affected file lib/silcclient/client_channel.c.
4599 * Added the support for the private keys in the channel message
4600 sending and encryption and in the message reception and
4601 decryption. Affected funtions are
4602 silc_client_send_channel_message and silc_client_channel_message.
4604 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4606 * Added SKE's key verify callback to the client library's
4607 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4609 * Removed the statement that server (or router) must send USERS
4610 command reply when joining to the channel so that the client
4611 knows who are on the channel. Instead, the client list and
4612 client's mode list is now sent in the JOIN command reply to the
4613 client who joined channel. This is better solution.
4615 * Added function silc_server_get_users_on_channel and function
4616 silc_server_save_users_on_channel to the silcd/server.[ch].
4618 * Removed function silc_server_command_send_users from the
4621 * Do not show topic on the client library anymore. The topic is
4622 sent in the command reply notify to the application and the
4623 application must show the topic now.
4625 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4627 * Added client searching by nickname hash into the IDENTIFY and
4628 WHOIS commands in the server as they were clearly missing from
4629 them. Affected file is silcd/command.c.
4631 * Fixed a bug in private message receiving in the client library.
4632 The remote ID was freed and it wasn't supposed, now it is
4635 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Minor fix to the channel payload; allocate the data area, as it
4638 needs to be of specific length.
4640 * If the key agreement port is zero then the operating
4641 system will define the bound port. Affected files are
4642 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4644 * Added new function silc_channel_payload_decrypt into the file
4645 lib/silccore/silcchannel.[ch].
4647 * Moved the channel message etc, check from silc_packet_decrypt
4648 to applications. The library calls now a generic
4649 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4650 when the packet is either normal or special. This was done to
4651 allow more wide range of checking that was not allowed when
4652 the code was in library. Now applications can do virtually any
4653 checks to the packet and return to the library the decision how
4654 the packet should be processed. Affected files are
4655 lib/silccore/silcpacket.[ch].
4657 Added silc_server_packet_decrypt_check to the server and
4658 silc_client_packet_decrypt_check to the client library.
4660 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4661 to send with specified source and destination information.
4663 * Channel message delivery between routers was broken after the
4664 channel key distribution was fixed earlier. The channel key
4665 was used be to distributed to other routers as well which is not
4666 allowed by the protocol. Now this is fixed and channel keys
4667 really are cell specific and the channel message delivery between
4668 routers comply with the protocol specification.
4670 * Fixed various commands in server to check also the global list
4671 for the channel entry and not just the local list. The affected
4672 file silcd/command.c.
4674 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Added assert()s to buffer formatting and unformatting routines
4677 to assert (if --enable-debug) when error occurs. Affected
4678 file: lib/silcutil/silcbuffmt.c.
4680 * Changed to auto-reconnect to check whether the remote host is
4681 router and register the re-connect timeout if it is. It used
4682 to check that whether we are normal server, but router must do
4683 auto-reconnect with another router as well. Affected file
4686 * Removed the [<key len>] option from CMODE command as the cipher
4687 name decides the key length, nowadays. See the defined ciphers
4688 from the protocol specification.
4690 * Added [<hmac>] option to the CMODE command to define the HMAC
4691 for the channel. Added SILC_CMODE_HMAC channel mode.
4693 * Added [<hmac>] option for the JOIN command so that user can
4694 select which HMAC is used to compute the MACs of the channel
4697 * Added Hmac field to the Channel Message Payload. The integrity
4698 of plaintext channel messages are now protected by computing
4699 MAC of the message and attaching the MAC to the payload. The
4700 MAC is encrypted. Now, it is clear that this causes some
4701 overhead to the size of the packet but rationale for this is that
4702 now the receiver can verify whether the channel message decrypted
4703 correctly and also when private keys are set for the channel the
4704 receiver can decrypt the packet with several keys and check from
4705 the MAC which key decrypted the message correctly.
4707 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4708 lib/silccrypt/silccipher.[ch].
4710 * Added silc_hash_len to return the digest length into the
4711 lib/silcrypt/silchash.[ch].
4713 * Rewrote parts of Silc Channel Payload interface in the
4714 lib/silccore/silcchannel.[ch]. The encode function now also
4715 encrypts the packet and parse function decrypts it.
4717 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Fixed a minor formatting bug in the SKE's key material processing.
4720 It actually might have processed the keys wrong way resulting
4723 * Redefined the mandatory HMAC algorithms and added new algorithms.
4724 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4725 and hmac-md5 truncated to 96 bits. The mandatory is now
4726 hmac-sha1-96. Rest are optional (including the one that used
4727 to be mandatory). Rationale for this is that the truncated HMAC
4728 length is sufficient from security point of view and can actually
4729 make the attack against the HMAC harder. Also, the truncated
4730 HMAC causes less overhead to the packets. See the RFC2104 for
4733 * Added new [hmac] configuration section. The SKE used to use
4734 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4735 is of course wrong. The official names that must be proposed in
4736 the SKE are the ones defined in the protocol specification
4737 (hmac-sha1-96 for example). The user can configure any hmac
4738 using any hash function configured in the [hash] section. At
4739 least, the mandatory must be configured.
4741 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4743 * Added HMAC list to the SKE proposal list. It has now both
4744 hash algorithm list and HMAC list. This makes the protocol
4745 incompatible with previous versions. The SKE now seems to work
4746 the way it is supposed to work, for the first time actually.
4748 * Defined plain Hash algorithms to the protocol specification.
4751 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Implemented support for key agreement packets into the server.
4754 Added functions silc_server_key_agreement and
4755 silc_server_send_key_agreement. Other than these functions,
4756 server has nothing to do with this packet.
4758 * Added support for private message key packets into the server.
4759 Added functions silc_server_private_message_key and
4760 silc_server_send_private_message_key.
4764 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4765 called in the protocol's final callback instead in the END
4766 protocol state. This makes a little more sense and in the same
4767 time in client we can use the same protocol routines for normal
4768 key exchange and to key agreement packet handling as well.
4770 * Added to both client's and server's KE protocol context the
4771 SilcSKEKeyMaterial pointer to save the key material. We will
4772 bring the key material to the protocol's final callback by doing
4773 this. The final callback must free the key material.
4775 * Added SKE's packet_send callback into client's KE protocol
4776 context so that the caller can choose what packet sending function
4777 is used. This way we can use different packet sending when
4778 doing normal SKE when doing key agreement packet handling (in
4779 the key agreement packet handling we do not want to encrypt
4782 * Implemented the responder side of the key agreement routines
4783 in the client. The client can now bind to specified port and
4784 accept incoming key negotiation. The key material is passed
4785 to the application after the protocol is over.
4787 * Implemented the processing of incoming Key Agreement packet
4788 in the client. Added function silc_client_key_agreement to
4791 * Implemented the intiator side of the key agreement routines
4792 in the client. The client can now initiate key agreement with
4793 another remote client. The key material is passed to the
4794 application after the protocol is over.
4796 * Created client_keyagr.c to include all the key agreement
4799 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4800 SILC_TASK_CALLBACK except that it is not static.
4802 * Created client_notify.c and moved the Notify packet handling
4803 from the client.[ch] into that file.
4805 * Created client_prvmsg.c and moved all private message and
4806 private message key routines from the client.[ch] into that file.
4808 * Create client_channel.c and moved all channel message and
4809 channel private key routines from the client.[ch] into that file.
4811 * Changed silc_client_get_client_by_id_resolve to resolve with
4812 WHOIS command instead of IDENTIFY command, in the file
4813 lib/silclient/idlist.c.
4815 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Implemented the SKE's responder side to the Client library.
4819 * When FAILURE is received to the protocol do not trust it
4820 blindly. Register a timeout to wait whether the remote closes
4821 the connection as it should do it, only after that process the
4822 actual failure. This was changed to both client and server.
4824 * Added client_internal.h to include some of the structures
4825 there instead of client.h in lib/silcclient/.
4827 * Added function silc_task_unregister_by_callback to unregister
4828 timeouts by the callback function.
4830 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Some "Incomplete WHOIS info" errors has been appearing on the
4833 log files. Took away the entry->userinfo check from WHOIS
4834 reply sending. The entry->userinfo is now " " if client did not
4835 provide one. I thought this was fixed earlier but something
4836 is wrong still. Let's see if the error still appears.
4838 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Fixed a minor bug in the login when the channel key is
4841 re-generated in the server. It used to generate the key in
4842 wrong order and thus caused problems in the channel traffic.
4844 * Fixed a minor bug in channel key distsribution after
4845 KICK command. The key was not sent to the router even though
4848 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Added silc_ske_process_key_material_data as generic routine
4851 to process any key material as the SILC protocol dictates. The
4852 function is used by the actual SKE library but can be used by
4853 applications as well. This relates to the private message keys
4854 and the channel private keys since they must be processed the
4855 same way the normal SILC session keys. The protocol dictates
4856 this. Affected files: lib/silcske/silcske.[ch].
4858 Added also silc_ske_free_key_material to free the
4859 SilcSKEKeyMaterial structure.
4861 * Defined silc_cipher_set_key function to set the key for
4862 cipher without using the object's method function. The affected
4863 files: lib/silccrypt/silccipher.[ch].
4865 * Implemented silc silc_client_add_private_message_key,
4866 silc_client_add_private_message_key_ske,
4867 silc_client_del_private_message_key,
4868 silc_client_list_private_message_keys and
4869 silc_client_free_private_message_keys functions in the
4872 Added functions silc_client_send_private_message_key to send
4873 the Private Message Key payload and silc_client_private_message_key
4874 to handle incoming Private Message Key payload.
4876 * Added Cipher field to the Private Message Key payload to set
4877 the cipher to be used. If ignored, the default cipher defined
4878 in the SILC protocol (aes-256-cbc) is used.
4880 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Removed lib/silcclient/ops.h file.
4884 Redefined parts of the SILC Client Library API. Created new
4885 file silcapi.h that deprecates the ops.h file and defines the
4886 published Client Library API. Defined also private message key
4887 API and channel private key API into the file.
4889 This is the file that the application must include from the
4890 SILC Client Library. Other files need not be included by
4891 the application anymore.
4893 * Added new key_agreement client operation callback and also
4894 defined the Key Agreement library API for the application.
4896 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4899 is used by clients to request key negotiation between another
4900 client in the SILC network. If the negotiation is started it
4901 is performed using the SKE protocol. The result of the
4902 negotiation, the secret key material, can be used for example
4903 as private message key.
4905 Implemented the Key Agreement payload into the files
4906 lib/silccore/silauth.[ch].
4908 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Redefined ciphers for the SILC protocol. Added some new ciphers
4911 and defined the key lengths for the algorithms. Changed the
4912 code accordingly. The default key length is now 256 bits.
4914 * Fixed SKE key distribution function silc_ske_process_key_material
4915 when the key length is more than 128 bits. The default key
4916 length in SILC is now 256 bits.
4918 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4919 to indicate unsupported algorithm.
4921 * Renamed rijndael.c to aes.c and all functions as well.
4923 * Fixed a long standing channel key setting bug in client library.
4924 Weird that it has never surfaced before.
4926 * Fixed bug in channel deletion. If the entire channel is removed
4927 then it must also delete the references of the channel entry
4928 from the client's channel list as the client's channel entry and
4929 the channel's client entry share same memory.
4931 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4933 * Implemented CONNECT and SHUTDOWN commands in the client.
4935 * Implemented CLOSE command to the client.
4937 * Added the function silc_idlist_find_server_by_name into the
4938 files silcd/idlist.[ch].
4940 Added the function silc_idlist_find_server_by_conn into the
4941 files silcd/idlist.[ch].
4943 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * DIE command was renamed to SHUTDOWN. Updated the both code
4948 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4949 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4951 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4954 * Added function silc_server_create_connection function to create
4955 connection to remote router. My server implementation actually
4956 does not allow router to connect to normal server (it expects
4957 that normal server always initiates the connection to the router)
4958 so the CONNECT command is only good for connecting to another
4961 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4964 or some other client was kicked from the channel.
4966 Implemented the handling of the notify type to both client
4969 Implemented silc_server_send_notify_kicked to send the KICKED
4970 notify. It is used to send it to the server's primary router.
4972 * Implemented the KICK command into server and client.
4974 * Added `query' argument to the silc_idlist_get_client function
4975 to indicate whether to query the client from server or not if
4978 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4979 to indicate that the client is not channel founder.
4983 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Removed the rng context from SilcPacketContext structure and
4986 changed that the packet routine uses the Global RNG API.
4988 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Added support for quit message that client can "leave" on the
4991 channel when it quits the SILC. It is ditributed inside the
4992 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4994 Added silc_server_free_client_data that will take the
4995 signoff message as argument.
4997 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4999 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Updated parts of the protocol specification to keep it up
5004 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5007 payloads in one packet.
5009 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5010 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5011 use now the new List flag.
5013 * Also deprecated the following packet types: REPLACE_ID,
5014 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5016 * Added list support for Notify packet in server.
5018 * Added silc_server_send_notify_channel_change to send the
5019 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5020 the silc_server_send_replace_id.
5022 * Added silc_server_send_notify_nick_change to send the
5023 NICK_CHANGE notify type. Deprecates the function
5024 silc_server_send_replace_id.
5026 * Added silc_server_send_notify_join to send the JOIN notify type.
5027 Deprecates the function silc_server_send_new_channel_user.
5029 * Added silc_server_send_notify_leave to send LEAVE notify type.
5030 Deprecates the function silc_server_send_remove_channel_user.
5032 * Added silc_server_send_notify_cmode and
5033 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5034 types. Deprecates the silc_server_send_set_mode function.
5036 * Added SERVER_SIGNOFF notify type to indicate that server has
5037 quit. This means that all clients on the channel from that
5038 server will drop. This can be also used when netsplit happens.
5040 Deprecated REMOVE_ID packet type since it is not needed anymore
5043 Added silc_server_send_notify_server_signoff to send the
5044 SERVER_SIGNOFF notify type. Deprecates the function
5045 silc_server_send_remove_id.
5047 Added also silc_server_send_notify_signoff to send the
5048 SIGNOFF notify type.
5050 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5051 SILC protocol from this day on. Changed the protocol
5052 specification as well.
5054 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5055 notify type. It is used between routers to notify about
5056 topic changes on a channel.
5058 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5061 * Partly updated the protocol specification to comply with the
5062 changes now made. It is still though a bit outdated.
5064 * The JOIN notify type now takes one extra argument <Channel ID>.
5065 The packet used to be destined to the channel but now the
5066 JOIN type may be sent as list thus it is impossible to
5067 destine it to any specific channel. By adding this argument
5068 it is again possible.
5070 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * Added CREDITS file. The CHANGES and CREDITS file will appear
5073 in the distribution as well.
5075 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5078 types in the server's silcd/packet_receive.c.
5080 * Implemented CMODE and CUMODE to work in router environment.
5082 * Fixed minor encoding and decoding buglet from the
5083 lib/silccore/silcmode.c.
5085 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5088 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5090 * Changed all SilcConfigServer* and silc_config_server* to
5091 SilcServerConfig* and silc_server_config*, respectively.
5094 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Associated the ID (client or server ID) to the Authentication
5097 Payload to avoid any possibility of forging. Updated the
5098 protocol specification and the code accordingly.
5100 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * The RSA key length is now save to the RsaKey context in the
5103 key generation process in lib/silccrypt/rsa.c. The key length
5104 is now used to figure out the maximum size of the block allowed
5105 to be encrypted/signed.
5107 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5108 is equivalent to the silc_mp_mp2bin but does not allocate any
5111 * Changed silc_mp_mp2bin API to take length argument. If it is
5112 non-zero then the buffer is allocated that large. If zero, then
5113 the size is approximated using silc_mp_sizeinbase, which however
5116 * Created Global RNG API which is global RNG that application can
5117 initialize. After initializing, any routine anywhere in the
5118 code (including library) can use RNG without allocating a new
5119 RNG object. This was done to allow this sort of use of the
5120 RNG in code that has no chance to allocate RNG object. All
5121 applications currently allocate this and many routines in the
5122 library use this. Affected file lib/silccrypt/silcrng.[ch].
5124 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5125 it to use the Global RNG API.
5127 * Defined Authentication Payload into protocol specification that
5128 is used during SILC session to authenticate entities. It is
5129 used for example by client to authenticate itself to the server
5130 to obtain server operator privileges.
5132 Implemented this payload into the lib/silccore/silcauth.[ch].
5133 Implemented also routines for public key based authentication
5134 as the new protocol specification dictates.
5136 Moved definitions of different authentication methods from
5137 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5139 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5140 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5141 silc_pkcs_verify_with_hash functions into the file
5142 lib/silccrypt/silcpkcs.[ch].
5144 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5146 * The client entry's userinfo pointer must be always valid.
5147 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5148 will fail since it requires the userinfo. Now, the userinfo
5149 is allocated as "" if actual userinfo does not exist. Actually,
5150 it must exist and it is totally Ok to drop client connections
5151 that does not announce the userinfo. However, we will make
5152 this workaround for now.
5154 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5155 to return the remote port by socket.
5157 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5160 SILC_SERVER_PENDING_EXEC and added an new macro
5161 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5162 data or when error occurs while processing the pending command.
5164 Added new argument `destructor' into silc_server_command_pending
5165 and to the SilcServerCommandPending object. This destructor is
5166 now called after calling the pending callback or if error occurs
5167 immediately. If error occurs the actual pending callback won't
5168 be called at all - only the destructor. The destructor may be
5169 NULL if destructor is not needed.
5171 All this applies for client library code as well. Similar
5172 changes were made there as well for the pending commands.
5174 In the client, the application must now allocate the
5175 SilcClientCommandContext with the silc_client_command_alloc
5178 * Added reference counter to the SilcServerCommandContext. Added
5179 function silc_server_command_alloc and silc_server_command_dup
5182 Same type of functions added to the client library for the same
5185 * Removed the cmd_ident from IDListData away since it is now
5186 global for all connections. It is the command identifier used
5187 in command sending and with pending commands. The affected file
5190 * Added reference counter to the SilcSocketConnection objecet to
5191 indicate the usage count of the object. The object won't be
5192 freed untill the reference counter hits zero. Currently only
5193 server uses this, and client ignores it. The client must be
5194 set to use this too later. The affected files are
5195 lib/silccore/silcsockconn.[ch]. Added also the function
5196 silc_socket_dup to increase the reference counter.
5198 This was mainly added because it is possible that the socket
5199 is removed underneath of pending command or other async
5200 operation. Now it won't be free'd and proper DISCONNECTING
5201 flags, etc. can be set to avoid sending data to connection that
5202 is not valid anymore.
5204 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5205 the connection. After that it sets SILC_SET_DISCONNECTED.
5206 It is, however, possible that the socket data is not still freed.
5207 The silc_server_packet_process now checks that data is not
5208 read or written to connection that is DISCONNECTED. The socket
5209 get's freed when the reference counter hits zero.
5211 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Changed the client operation API: channel_message operation's
5214 `sender' is now the client entry of the sender, not the nickname
5215 and the `channel' is the channel entry, not the channel name.
5217 In the private_message operation the `sender' is now also the
5218 client entry of the sender not the nickname.
5220 Affected file is lib/silcclient/ops.h and all applications
5221 using the client operations.
5223 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Moved the calling of ops->connect() from connect_to_server_final
5226 into receive_new_id functin since that is the point when the
5227 client is actually allowed to send traffic to network. The
5228 affected file is lib/silcclient/client.c.
5230 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5233 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5234 (if needs broadcasting) instead of broadcasting the packets one
5235 by one which would make a burst in the network traffic.
5237 * Added `broadcast' argument to the functions in silcd/server.[ch]
5238 silc_server_create_new_channel[_with_id] to indicate whether
5239 to send New Channel packet to primary router.
5241 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Added new function into the silcd/server.[ch] files:
5244 silc_server_create_new_channel_with_id to create new channel with
5245 already existing Channel ID.
5247 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5248 lib/silccore/silcpacket.h. This packet is used t send list of
5249 Set Mode payloads inside one packet. Server uses this to set
5250 the modes for the channels and clients on those channels, that it
5251 announced to the router when it connected to it. The protocol
5252 specification has been updated accordingly.
5254 * The silc_server_new_channel did not handle the packet coming
5255 from normal server as it normally does not send that. However,
5256 when it announces its channels it does send it. Implemented
5257 the support for that.
5259 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5260 into the file lib/silccore/id.h.
5262 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Fixed memory leaks in the functions silc_idlist_del_client,
5265 silc_idlist_del_channel and silc_idlist_del_server in the file
5266 silcd/idlist.c. All of those leaked like a sieve.
5268 * Fixed some small memory leaks in the client's function
5269 silc_client_notify_by_server.
5271 * Added functions into silcd/server.c: silc_server_announce_clients,
5272 silc_server_announce_channels and silc_server_announce_server.
5273 These functions are used by normal and router server to announce
5274 to its primary router about clients, channels and servers (when
5275 router) that we own. This is done after we've connected to the
5278 These functions effectively implements the following packet types:
5279 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5280 and SILC_PACKET_NEW_ID_LIST.
5282 * Added new functions into the silcd/packet_receive.[ch]:
5283 silc_server_new_id_list, silc_server_new_channel_list and
5284 silc_server_new_channel_user_list to handle the incoming
5285 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5287 * Added support of changing Channel ID in the function
5288 silc_server_replace_id. If the server that announces a channel
5289 to the router already exists in the router (with same name but
5290 with different Channel ID), router is responsible to send
5291 Replace ID packet to the server and force the server to change
5292 the Channel ID to the one router has.
5294 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5295 client that the Channel ID has been changed by the router. The
5296 normal server sends this to the client. Client must start using
5297 the new Channel ID as the channel's ID.
5299 Implemented handling of this new type into lib/silcclient/client.c
5300 into the function silc_client_notify_by_server.
5302 * Added new function silc_idlist_replace_channel_id into the files
5303 silcd/idlist.[ch] to replace the Channel ID.
5305 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Call silc_server_command_identify_check always when processing
5308 the IDENTIFY command in silcd/command.c
5310 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5313 send keepalive packets. The packet can be sent by clients,
5314 servers and routers.
5316 Added function silc_socket_set_heartbeat into the file
5317 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5318 If not set, the heartbeat is not performed. The actual
5319 heartbeat is implemented in the low level socket connection
5320 library. However, application is responsible of actually
5323 Added silc_server_send_heartbeat to send the actual heartbeat
5324 packet into silcd/packet_send.[ch]. Server now performs
5325 keepalive with all connections.
5327 * Added silc_task_get_first function into lib/silcutil/silctask.c
5328 to return the timeout task with shortest timeout. There was a bug
5329 in task unregistration that caused problems. TODO has been
5330 updated to include that task system must be rewritten.
5332 * The client library will now resolve the client information when
5333 receiving JOIN notify from server for client that we know but
5334 have incomplete information.
5336 * Rewrote parts of silc_server_remove_from_channels and
5337 silc_server_remove_from_one_channel as they did not remove the
5338 channel in some circumstances even though they should've.
5340 * Encryption problem encountered in server:
5342 The LEAVE command used to send the Channel Key packet to the
5343 router immediately after generating it. However, the code
5344 had earlier sent Remove Channel user packet but not immediately,
5345 ie. it was put to queue. The order of packets in the router
5346 was that Channel Key packet was first and Remove Channel User
5347 packet was second, even though they were encrypted in the
5348 reverse order. For this reason, MAC check failed. Now, this
5349 is fixed by not sending the Channel Key packet immediately but
5350 putting it to queue. However, this is more fundamental problem:
5351 packets that are in queue should actually not be encrypted
5352 because packets that are sent immediately gets encrypted
5353 actually with wrong IV (and thus MAC check fails). So, packets
5354 that are in queue should be encrypted when they are sent to
5355 the wire and not when they put to the queue.
5357 However, the problem is that the current system has not been
5358 designed to work that way. Instead, the packet is encrypted
5359 as soon as possible and left to the queue. The queue is then
5360 just purged into wire. There won't be any fixes for this
5361 any time soon. So, the current semantic for packet sending
5364 o If you send packet to remote host and do not force the send
5365 (the packet will be in queue) then all subsequent packets to the
5366 same remote host must also be put to the queue. Only after the
5367 queue has been purged is it safe again to force the packet
5370 o If you send all packets immediately then it safe to send
5371 any of subsequent packets through the queue, however, after
5372 the first packet is put to queue then any subsequent packets
5373 must also be put to the queue.
5375 Follow these rules and everything works fine.
5377 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * Added new function silc_server_remove_clients_by_server to
5380 remove all client entries from ID list when the server connection
5381 is lost. In this case it is also important to invalidate all
5382 client entires as they hold the invalid server entry. This
5383 fixes fatal bug when server has lost connection and will reconnect
5386 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Made some sanity checks to silc_server_daemonise like to check
5389 whether the requested user and group actually exists.
5391 * Added sanity check to SKE's silc_ske_responder_finish to check
5392 that the public and private key actually is valid.
5394 * Invalidate the client's nickname when receiving Replace ID
5395 packet and the Client ID is being replaced. This means that the
5396 server will query the nickname if someone needs it (client)
5399 * Sort the ID Cache in client library when the ID Cache data
5400 has changed (needs sorting).
5402 * Do not allow for SILC client to create several connections to
5403 several servers. The client does not support windows right now
5404 and generating multiple connections causes weird behaviour.
5406 Irssi-silc client does support windows and can handle several
5407 connections without problems, see: www.irssi.org and SILC plugin.
5409 * Fixed some places where client was added to the IDList. The
5410 rule of thumb is following (in order to get everything right):
5411 If the client is directly connected local client then the
5412 `connection' argument must be set and `router' argument must be
5413 NULL to silc_idlist_add_client function. If the client is not
5414 directly connected client then the `router' argument must
5415 bet set and the `connection' argument must be NULL to the
5416 silc_idlist_add_client function.
5418 * The funtion silc_server_packet_send_local_channel actually did
5419 not check whether the client was locally connected or not. It
5420 does that now. Fixed a bug related to LEAVE command.
5422 * Fixed Remove Channel User payload parsing bug in server's
5423 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5425 * The server's silc_server_save_channel_key now checks also the
5426 global ID list for the channel as it might not be in the local
5427 list. Fixed a bug related to LEAVE command.
5429 * Is this the end of the [<unknown>] buglet that has been lurking
5430 around for a long time? A little for loop fix in server's
5431 silc_server_command_whois_parse that is used by both IDENTIFY
5432 and WHOIS command. At least, this was a clear bug and a cause
5433 of one type of [<unknown>] buglet.
5435 * WHOIS and IDENTIFY commands call the function
5436 silc_server_command_[whois/identify]_check function even if
5437 we are not router server.
5439 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5441 * Added --with-gmp configuration option. If set the GMP
5442 is always compiled in the SILC source tree. If not set then
5443 it is checked whether the system has the GMP3 installed. If
5444 it has then the GMP won't be compiled (the system's headers
5445 and library is used), if it doesn't have it then the GMP is
5446 compiled in the SILC source tree.
5448 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Changed RSA private exponent generation to what PKCS #1
5451 suggests. We try to find the smallest possible d by doing
5452 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5453 not security fix but optimization.
5455 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Added new config entry [Identity] to fork the server and run
5458 it as specific user and group. A patch from Bostik.
5460 * Imported Dotconf configuration library into lib/dotconf.
5461 This will be used to create the SILC configuration files later.
5462 It will appear in the distsribution after this commit.
5464 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * A big code auditing weekend happening. Auditing code for
5467 obvious mistakes, bugs and errors. Also, removing any code
5470 Removed files for being obsolete:
5472 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5473 inline in the file lib/silcutil/silcbuffer.h)
5475 o lib/silcutil/silcbufutil.c (the header has inline versions)
5477 Changed code to fix possible error conditions:
5479 o The buffer formatting routines now check that the destination
5480 buffer really has enough space to add the data. This applies for
5481 both buffer formatting and unformatting
5482 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5483 unformatting was changed to accomodate following rules:
5484 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5485 sent to the function while XXX_*STRING will not allocate or copy
5486 the data into the buffer. Instead it sets the pointer from the
5487 buffer into the pointer sent as argument (XXX_*STRING used to
5488 require that the pointer must be allocated already). This change
5489 makes this whole thing a bit more consistent and more optimized
5490 (note that the data returned in the unformatting with XXX_*STRING
5491 must not be freed now). The routines return now -1 on error.
5493 o Tried to find all code that use buffer_format and buffer_unformat
5494 and added return value checking to prevent formatting and
5495 especially unformatting errors and possible subsequent fatal
5498 o Changed ske->x and ske->KEY to mallocated pointers in
5499 lib/silcske/silcske.h. Fixed possible data and memory leak.
5501 o Added return value checking to all *_parse* functions. Fixed
5502 many memory leaks as well.
5504 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5505 so that buffer overflows would not happen. All code now also
5506 checks the return value as it can fail.
5508 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5510 * Added reconnection support to server if the normal server looses
5511 its connection to the router (for example if router is rebooted).
5512 The server performs normal reconnection strategy implemented
5513 to the server. Affected file silcd/server.c.
5515 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Added new packet type SILC_PACKET_SET_MODE that is used to
5518 distribute the information about changed modes (for clients,
5519 channels and clients channel modes) to all routers in the
5520 network. Updated the protocol specification accordingly.
5522 Added functions into silcd/packet_send.c and
5523 silcd/packet_receive.c: silc_server_send_set_mode,
5524 silc_server_set_mode.
5526 Added new files silcmode.[ch] into lib/silccore that implements
5527 the encoding and decoding of Set Mode Payload. Added new type
5528 SilcSetModePayload. Moved the definitions of different modes
5529 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5531 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5533 * Oops, a little mistake in server's connection authentication
5534 protocol. The protocol is not ended with FAILURE but with
5535 SUCCESS if the authentication is Ok. :) Affected file is
5538 * Implemented NICK_CHANGE notify handling in server in the file
5539 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5540 the local clients on the channel. After the changing nickname
5541 in router environment snhould work and the [<unknown>] nickname
5542 should appear no more.
5544 The silc_server_replace_id function that receives the Replace ID
5545 payload now sends the NICK_CHANGE notify type also in the file
5546 silcd/packet_receive.c
5548 * Changed WHOIS and IDENTIFY command to support the maximum amount
5549 of arguments defined in protocol specs (3328 arguments). This
5550 fixed a bug that caused problems when there were more than three
5553 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Added extra parameter, command identifier, to the
5556 silc_client_send_command so that explicit command identifier
5559 Changed that ID list routines uses specific command identifier
5560 when sending WHOIS/IDENTIFY requests to the server so that they
5561 can be identified when the reply comes back.
5563 Affected files lib/silcclient/command.[ch],
5564 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5566 * Added `sender' argument to silc_server_packet_send_to_channel
5567 to indicaet the sender who originally sent the packet to us
5568 that we are now re-sending. Ignored if NULL. Affected file
5569 silcd/packet_send.[ch].
5571 * Added some server statistics support in silcd/server_internal.h
5572 SilcServerStatistics structure and around the server code. Also
5573 send some nice statistics information when client is connecting
5576 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5578 * Fixed channel ID decoding in server's JOIN command reply in
5579 silcd/command_reply.c
5581 * Fixed braodcasting of replace ID payload to not to send it if
5582 we are standalone server in silcd/packet_receive.c.
5584 * Fixed all channel message sending routines to not to send
5585 packets to clients that has router set, since they are routed
5586 separately in the same function earlier. Affects file
5587 silcd/packet_send.c and all channel packet sending functions.
5589 * In USERS reply, res_argv[i] are not allocated, the table
5590 is allocated. Thus changed that free the table, not its
5593 * In server's whois_check and identify_check if the client is
5594 locally connected do not send any WHOIS commands - they are not
5597 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * Fixed some minor bugs in client when sending WHOIS command. The
5600 arguments was in wrong order.
5602 * Removed statis function add_to_channel from server in
5603 silcd/command.c that was previously used with the joining but
5606 * Tested USERS command in router environment successfully with two
5607 routers, two servers and two clients.
5609 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Reorganized the USERS command and command reply in client library
5612 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5613 When the command is given by user we register a pending command
5614 callback that will reprocess the command after the reply has been
5615 received from the server. When reprocessing the packet we then
5616 display the information. Thus, the USERS information is displayed
5617 now in the command callback instead of in the command reply
5618 callback. The processing of the command is same as previously
5619 when server has sent the command reply in the JOINing process.
5621 * Added to USERS command in silcd/command_reply.c to join the client,
5622 we didn't use to know about, to the channel after we've created
5623 a client entry for it. Also, for clienet we did know already still
5624 check whether it is on the channel or not and add it if not.
5626 * Removed silc_server_command_join_notify as the function and its
5629 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Changed the client's pending command handling to the same as the
5632 server's pending command handling. It is also now possible to
5633 execute command reply functions from other command reply
5634 function as the function callbacks for commands and command
5635 replies are one and same. The pending commands are not static
5636 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5637 in client connection context. Thus, pending commands are server
5638 connection specific as it is convenient.
5640 Changed the function silc_client_command_pending and
5641 silc_client_command_pending_del and added new function
5642 silc_client_command_pending_check. Removed the
5643 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5646 * Added cmd_ident, current command identifier, to the client
5647 connection context in lib/silcclient/client.h to keep track on
5648 command identifiers used in command sending. Client's command reply
5649 function handling now supports the mandatory command identifiers.
5651 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5652 funtions in client to fully support pending command callbacks.
5654 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5655 as one of the arguments to the application in the command reply
5658 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5659 before first releasing SILC but came back. Now it is removed again
5660 and should come back nomore. The FORWARDED flag was used only
5661 by the JOINing procedure by forwarding the command packet to router.
5662 Now, the JOINing procedure has been changed to more generic (due
5663 to various router environment issues) and FORWARDED is not needed
5664 anymore for anything. The protocol specification is yet to be
5667 Now, removed silc_server_packet_forward from server and the flag
5668 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5670 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Renamed NAMES command to USERS command. The NAMES was named that
5673 due to historical reasons. Now it is renamed. Also, rewrote
5674 parts of the USERS command. The nickname list is not sent anymore
5675 by the server. Only Client ID and mode lists are sent in the USERS
5676 command. Changed this also to the protocol specification.
5678 The client now resolves the names and stuff after it receives
5679 the USERS list from the server when joining to the channel.
5681 * WHOIS and IDENTIFY commands has been changed to support multiple
5682 Client ID's per command. One can now search for multiple users
5683 in the network by sending only one WHOIS or IDENTIFY command.
5684 Changed the code and the protocol specifications.
5686 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5687 uses silc_server_command_whois_parse to parse the request. */
5689 * If normal server, do not parse the WHOIS and IDENTIFY requests
5690 before sending it to the router. Saves some time.
5692 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5694 * Fixed JOIN command on client library. Wrong number of arguments
5695 used to crash the client.
5697 * Added silc_server_channel_has_global function to check whether
5698 channel has global users or not.
5700 * Added silc_server_channel_has_local function to check whether channel
5701 has locally connected clients on the channel.
5703 * The silc_server_remove_from_one_channel now checks whether the
5704 channel has global users or not after given client was removed from
5705 the channel. It also checks whether the channel has local clients
5706 on the channel anymore. If it does not have then the channel entry
5707 is removed as it is not needed anymore.
5709 * The silc_server_notify now checks on JOIN notify whether the joining
5710 client is one of locally connected or global. If it is global then
5711 the channel has now global users on the channel and that is marked
5712 to the channel entry. Also, it now saves the global client to
5713 global list who is joining and JOINs it to the channel. This is
5714 for normal server, that is.
5716 Changed silc_server_send_notify_on_channel,
5717 silc_server_packet_relay_to_channel and
5718 silc_server_packet_send_to_channel check if we are normal server
5719 and client has router set (ie. global client) do not send the
5720 message to that client, as it is already routed to our router.
5722 * Implemented LEAVE notify type handling in silc_server_notify
5725 * Tested LEAVE command in router environment successfully. Tested
5726 with two routers, two servers and two clients.
5730 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5732 * Implemented SIGNOFF notify type handling in silc_server_notify
5735 * silc_server_remove_id now removes the client entry from all channels
5736 it has joined and thusly sends SIGNOFF notify type.
5738 * Rewrote the NAMES list generation in server by removing two excess
5739 loops. The lists are created now inside one loop.
5741 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * silc_server_remove_channel_user checks now also global list
5744 for channel and client.
5746 * silc_server_new_channel_user checks now both local and global
5747 list for channel and client. Fixed a bug in client id decoding.
5748 Used to decode wrong buffer.
5750 * silc_server_channel_message checks now both local and global
5751 list for channel entry.
5753 * Tested channel joining (hence JOIN) in router environment
5754 successfully. Tested with two routers, two servers and two
5757 * Tested channel message sending in router environment successfully.
5759 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Added silc_server_save_channel_key into server.[ch] to save the
5762 received channel key in Channel Key payload processing. It is
5763 also used in JOIN command reply handling.
5765 Equivalent function silc_client_save_channel_key added into
5766 client.[ch] into client library.
5768 * Changed JOIN command reply to send information whether the channel
5769 was created or not (is existing already) and the channel key
5770 payload. Changed protocol specs accordingly.
5772 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5773 the request was sent by ID and not by nickname. Crashed on
5776 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5779 now correctly save the received data.
5781 * silc_server_free_sock_user_data now notifies routers in the
5782 network about entities leaving the network.
5784 At the same time implemented functions silc_server_remove_id
5785 and silc_server_send_remove_id to receive and send REMOVE_ID
5786 packets. The packet is used to notify routers in the network
5787 about leaving entities. The ID removed will become invalid in
5790 * Added function silc_idlist_del_server into server. Removes and
5791 free's server entry from ID list.
5793 * silc_server_private_message function now checks, if we are router,
5794 that the destination ID really is valid ID, naturally.
5796 * In router when NEW_ID packet is received (for new client) the
5797 hash of the Client ID is saved in the ID Cache but the
5798 client->nickname is set to NULL, instead of putting the hash
5801 IDENTIFY command now also checks that client->nickname must be
5802 valid. If it is not if will request the data from the server who
5803 owns the client. Added new function
5804 silc_server_command_identify_check.
5806 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5807 to set the command to already allocated Command Payload.
5809 * Tested private message sending in router environment with two
5810 routers, two servers and two clients. Fixed minor bugs and now
5813 * Fixed segfault from client's NAMES command. Used to crash if
5816 * Forwarded packets must not be routed even if it is not destined
5817 to the receiver. Changed server code comply with this.
5819 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Added `require_reverse_mapping' boolean value to ServerParams
5822 structure. If TRUE (not default) the server will require that
5823 the connecting host has fully qualified domain name.
5825 If the reverse mapping is not required and hostname could not be
5826 found the IP address is used as hostname.
5828 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5830 * Implemented version string checking to both client and server.
5831 The check is incomplete currently due to the abnormal version
5832 strings used in development version of SILC.
5834 * Changed all command functions in server to use the new
5837 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * Changed char *data to unsigned char *data in ID Cache system to
5840 support binary data as ID Cache data. Changed code to support
5841 binary data in lib/silccore/idcache.c.
5843 * Renamed silc_server_packet_relay_command_reply to
5844 silc_server_command_reply as it is normal packet receiving
5845 function. Rewrote the function to accept command replys for
5846 servers and not only for clients.
5848 * Mark remote router always as registered server if we are connecting
5849 to it. Otherwise, commands sent by the router to us are ignored.
5851 * All ID List find routines now returns the ID Cache Entry pointer
5852 as well if requested.
5854 * WHOIS command works now in router environment, tested with two
5855 routers, two servers and two clients.
5857 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5858 in router environment (as it is almost equivalent to WHOIS) but
5859 hasn't been tested thoroughly. Added new functions:
5861 silc_server_command_identify_parse
5862 silc_server_command_identify_send_reply
5863 silc_server_command_identify_from_client
5864 silc_server_command_identify_from_server
5866 * Disabled route cache adding because adding two different ID's with
5867 same IP replaces the old cache entry thus giving wrong route.
5868 The entry->router->connection is always the fastest route anyway
5869 so route cache may not be needed. Of course, new routes maybe
5870 established after receiving the ID when the entry->router->connection
5871 might not be anymore the most optimal.
5873 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Add route cache for received ID for fast routing.
5877 * Added silc_server_packet_route to route received packet on router
5878 that is not destined to us.
5880 * Renamed silc_server_get_route to silc_server_route_get.
5882 * Added id_string and id_string_len fields into SilcServer to
5883 include encoded ServerID for fast comparing without excess
5884 encoding of the ID's.
5886 * Cleaned up WHOIS command on server side. Added following static
5889 silc_server_command_whois_parse
5890 silc_server_command_whois_check
5891 silc_server_command_whois_send_reply
5892 silc_server_command_whois_from_client
5893 silc_server_command_whois_from_server
5895 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5896 arguments in command replies. All command functions should be
5897 updated to use this macro.
5899 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5901 * Minor typo fixes on command reply handling on server.
5903 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Added silc_server_command_add_to_channel internal routine to add
5906 the client to the channel after router has created the channel and
5907 sent command reply to the server.
5909 * Added generic silc_server_send_command to send any command from
5912 * Use static buffer with ID rendering instead of duplicating data.
5914 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Fixed a channel user mode bug when joining to a channel server gave
5917 everybody channel founder rights, oops.
5919 * We mark ourselves as the router of the incoming server connection
5920 if we are router ourselves. This way we can check in some packet
5921 sending functions whether it is locally connected server. For
5922 incoming router connections we put NULL.
5924 * For router sending packets locally means now always sending the
5925 packet cell wide; to local clients and local servers. For normal
5926 server sending packet locally means sending it to only local
5929 * Fixed the JOIN command to really work in router environment. If the
5930 channel is created it is always created by the router. Router is
5931 also responsible of making the initial joining to the channel,
5932 sending JOIN notify to the sending server and distributing
5933 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5934 does not exist server doesn't do anything else but forward the
5935 command to the router which performs everything.
5937 * Added silc_server_send_channel_key function to send the Channel Key
5940 * Added silc_server_create_channel_key to create new channel key. The
5941 channel key is now re-generated everytime someone joins or leaves
5942 a channel, as protocol dictates. Note: channel->key_len is the
5945 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5948 packet_receive.[ch] to separate packet sending and receiving
5949 routines. The server.[ch] now includes everything else including
5950 actual packet processing (writing and reading data) and other
5953 Renamed silc_server_private_message_send_internal to
5954 silc_server_send_private_message. The routine is still though
5955 used only to relay private messages as server does not send
5956 private messages itself.
5958 Renamed silc_server_new_channel to silc_server_create_new_channel
5959 and added new function sicl_server_new_channel that handles the
5960 incoming New Channel packet. Added also new sending function
5961 silc_server_send_new_channel to send New Channel Payload.
5963 * Added new function silc_server_notify to process incoming notify
5964 packet to the server/router. Server may then relay the notify
5965 to clients if needed.
5967 * Added new function silc_server_new_channel_user to process incoming
5968 New Channel User packet. Router will redistribute the packet and
5969 send JOIN notify to its local clients and locally connected servers
5970 if needed. Normal server will send JOIN notify to its local client
5971 on same channel when received this packet. Added also corresponding
5972 sending function silc_server_send_new_channel_user to sent the
5975 * Added boolean route argument to send_notif_to_channel and
5976 packet_send_to_channel functions to attempt to route the packet
5977 if it is TRUE and send only locally if it is FALSE.
5979 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * silc_server_replace_id now broadcasts the received replace ID
5982 packet if it is not broadcast packet already. The router must
5983 broadcast to inform other routers about changed ID.
5985 * Added backpointer to server's router into SilcServer context in
5986 silcd/server_internal.h.
5988 * Fixed silc_server_packet_broadcast to send correct broadcast
5991 * The channel key is now distributed to the local client as soon
5992 as it is received from the router (in router environment) so that
5993 no other packet may be sent for the channel until client has
5996 * silc_server_remove_channel_user now broadcasts the received
5997 Remove Channel User packet if it is not broadcast packet already.
5998 The router must broadcast to inform other routers about removed
6001 * Added users field into SilcPacketContext that is a reference count
6002 of the context. One can increase the reference count by calling
6003 silc_packet_context_dup which is now changed to just increase the
6004 reference count instead of duplicating the data. The reference
6005 count is decresed by calling silc_packet_context_free that will
6006 free the data after the reference count hits zero.
6008 For now on the packet context and everything allocated into it
6009 (including the raw packet from network) must be freed by calling
6010 the new silc_packet_context_free function. Added also new function
6011 silc_packet_context_alloc that must be used now to allocate the
6012 context. This also means that if a routine is asynchronous from
6013 silc_[client/server]_packet_parse_type the packet context must
6014 be duplicated by calling silc_packet_context_dup. Otherwise it
6015 gets free'd after silc_[client/server]_packet_parse_type returns.
6016 Also, one must remember that if packet is duplicated then its
6017 reference count must be decresed by calling the free function as
6018 many times as it was duplicated.
6020 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6021 from both client and server.
6023 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Made joining to a channel working in router environment.
6027 * Cleaned up JOIN command on server side and create function
6028 silc_server_command_join_channel internal routine to make the
6031 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6033 * Changed silc_command_pending list to SilcDList. Also, added
6034 `ident' field to SilcServerCommandPending structure to identify
6035 the reply and to call correct callback.
6037 Added silc_server_command_pending_check function to replace the
6038 corresnponding macro. The silc_command_pending list is not
6041 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6042 to set identifier to previously allocated Command Payload. It
6043 is used to set identifier for command when resending Command
6046 * Added silc_command_payload_encode_payload to encode Command
6047 Payload buffer from SilcCommandPayload structure.
6049 * Added silc_argument_payload_encode_payload to encode Argument
6050 payload buffer from SilcArgumentPayload structure.
6052 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * Changed WHOIS command to support router connection on server side.
6055 The whois request is always sent to router unless the server is
6056 standalone server. After server has received the reply from the
6057 router will it send the reply to the client.
6059 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6060 broadcast received broadcast packet. The function is used only
6061 by router. The broadcast packet is always sent to the router's
6064 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6065 render given ID to printable string, for log files for example.
6067 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * Made basic router to router connections working. At least they
6070 can now connect to each other but nothing really works the way
6071 they are supposed - yet.
6073 * Added new initiator token to RouterConnection configuration
6074 file in silcd/serverconfig.[ch]. It is used to tell whether we
6075 are the initiator to the remote router or whether we'll expect
6076 the other end to connect.
6078 * Moved registering of listener task to silc_server_init, hence
6079 the server starts listenning as soon as it is run, even if it
6080 does not have connections to other routers. Let's see how well
6083 * Changed default connection retry timeouts for more suitable in
6086 * Removed cipher and such arguments from silc_idlist_add_client
6087 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6088 Added new function silc_idlist_add_data to add the keys and stuff
6091 * Added SilcIDListData structure and added it to SilcClientEntry
6092 and SilcServerEntry as their first field in the structure. This
6093 way we can explicitly cast the ID entries to the SilcIDListData
6094 structure and get common data for the entries. In past, we had
6095 to first check what type of connection it is and then cast it to
6096 correct ID entry type. Now, we can directly cast the opaque
6097 pointer to the SilcIDListData (no matter what ID entry it actually
6098 is) and get the data needed.
6100 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6102 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6103 in some circumstances even if threre were timeout tasks, though not
6104 IO tasks, but tasks anyway. Now fixed.
6106 * Defined SilcServerConnection structure to hold connection specific
6107 stuff about directly connected servers and routers. The definition
6108 is currently in silcd/server_internal.h. I thought about having
6109 a bit more important role fro this struct but for now it is used
6110 only when connecting to other server (or router actually).
6112 * Added connecting retry support in server when connecting to
6113 router(s). The retry feature implement exponential backoff
6114 algorithm. Also, added SilcServerParams structure to hold default
6115 parameters for server. For now, it include these retry settings
6116 and are hard coded. After server is moded to be as Silc Server
6117 Library this structure will be more important.
6119 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * Changed client librarys channel->clients table to SilcList and
6122 changed code accordingly.
6124 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Changed client's channel table to SilcList and changed code
6127 accordingly. Also changed SilcChannelClientEntry to include back-
6128 pointer to the channel so that client entry can use that structure
6129 as list as well and we have fast cross-reference to the channel.
6130 This change dramatically decreased the complexity of channel
6131 handling with client entry and vice versa (removed one extra
6132 loop when searching for channel entry from many functions).
6134 * Changed server->sim from table to SilcDList and changed code
6137 * NAMES command can now be used from user interface. It will show
6138 the user list on the channel, neatly.
6140 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6141 Code now saves realname of the user if it becomes available.
6143 * Renamed configure.in to configure.in.pre and made ./prepare
6144 script to automatically add correct version string to
6145 configure.in which it creates from configure.in.pre.
6147 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6149 * NAMES command reply now shows users mode with the nickname when
6152 * Moved silc_client_ch[u]mode[_char] functions from
6153 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6154 place sucks, they are utility functions and should be in some
6157 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6159 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6162 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Added TRQ (efficient deque and list library) into lib/trq. This is
6167 a very good list library that is currently used in the SILC. Defined
6168 SilcList API over the library because I didn't like the API very
6169 much. See lib/trq/silclist.h for the API and examples of how to
6170 use the API. Fixed various places in the code to use the new
6171 SilcList API. The SilcList is meant for lists that has a structure
6172 already defined as a list. It is not suitable to add just some
6173 context to the list (in TRQ, the context is the list actually).
6175 So, I defined SilcDList that can be used for the purpose where
6176 predefined list structure does not exit. This can be used as
6177 such list. Now some context just can be added to the SilcDList.
6178 Currently this list is not used in the SILC just yet, though there
6179 are a lot places where this can replace dynamically allocated
6180 tables and I will fix these places, later, to use SilcDList.
6181 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6182 and use TRQ internally).
6184 Also fixed some annoying warning messages that the original TRQ
6185 code generated. Also minor changes to TRQ's Makefile.in.
6187 * Added support for querying by Client ID to both WHOIS and
6188 IDENTIFY commands into server, as required by the protocol.
6190 * Removed method function pointers from SilcBuffer structure. They
6191 weren't used to anything and just increased the context size for
6192 no good reason. This change also made silc_buffer_alloc and
6193 silc_buffer_free functions inline functions.
6195 * Disabled command flooding detection support until it's fixed so
6196 that it accepts commands in but does not execute them more than once
6199 * Added silc_net_localhost(), to return local hostname, into
6200 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6201 that must be initialized before calling silc_client_init.
6203 * Added new function: silc_server_send_notify_on_channels to send
6204 notify messages to all channels client has joined. It is assured
6205 that the message is sent only once per client.
6207 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6208 lib/silcutil/silcutil.[ch] as silc_format function. The new
6209 function is generic and is used by server as well, not only by
6210 the logging routines.
6212 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6213 the provided version string was not acceptable. Added new function:
6214 silc_ske_check_version into lib/silcske/silcske.h. The function
6215 must be implemented by the application (client or server) and it
6216 does not reside in the SKE library. The function checks the version
6217 string remote end sent.
6219 * Added back pointers (to opaque context and to SilcSocketConnection)
6220 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6222 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6223 duplicate packet context structure.
6225 * Changed `notify' client operation to send same arguments as client
6226 receives from server except for ID's. ID's are mapped to correct
6227 ID entry and that is returned. Also, if channel entry is not sent
6228 by server but the notify is for channel the channel entry is sent
6229 to application (otherwise application doesn't know that it is for
6230 channel (library gets it from packet's Destination ID)).
6232 * Added silc_client_remove_from_channels into client library to
6233 remove a client from all channels it has joined to. Used when
6234 received SIGNOFF notify from server. Added also new function
6235 silc_client_replace_from_channels to replace old ID entry with
6236 new ID entry on all channels. Used when received NICK_CHANGE
6239 * Fixed ID Cache list handling in silc_idlist_get_client in
6240 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6241 to get (or query) client by ID.
6243 * Updated TODO list.
6245 * Added connection authentication status message defined by the
6246 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6247 support for these into the code in client and server side.
6249 * Added generic function silc_client_send_command to send any command
6250 with variable argument list. Application should use this function
6251 to send commands if the command functions provided by the library
6252 does not suite for the application's user interface needs.
6254 * Added new `failure' client operation. Application is notified about
6255 received failure packet if client is executing a protocol. In this
6256 case the protocol's execution has failed.
6258 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6259 is required by the protocol.
6261 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6262 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6265 * Added status flag to SilcSKE object to indicate realtime status
6266 of the SKE protocol.
6268 * Application receives now exactly same command reply arguments as
6269 the library receives from server. However, if ID is received the
6270 corresponding ID entry is returned to the application (eg. Client
6271 ID is mapped to correct SilcClientEntry entry and that is returned).
6272 Changed command_reply client operation due to this change.
6274 * Changed all ID's in commands and in command replys as ID Payloads.
6275 Change affected both client and server side codes.
6277 All ID's sent in SILC network (with execption of ID's in SILC
6278 Packet header) are sent in ID Payload to support variable length
6281 * Server now notifies nick changes and notifies all clients on
6282 the channels about the new nickname (about the new Client ID,
6285 * Implemented CMODE command to change channel modes. Supports all
6286 channel modes defined by the protocol specs except ban and invite
6287 lists. (Also, private channel key mode is supported but support for
6288 setting private channel key in client is missing, thus, this mode
6289 has no effect on client side (except that server requires that the
6290 client uses private channel key and normal channel traffic does not
6293 Also, invite mode works per se, but INVITE command does not work
6294 yet correctly, so you can set channel as invite only channel but
6295 inviting clients to the channel does not work (it is yet to be
6296 thought what's the best way to do it).
6298 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6299 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6300 Implemented CUMODE command to change user's mode on the channel.
6301 Supports all modes defined by the protocol specs.
6303 * Added NAMES command reply to return users modes on the channel.
6305 * Removed unnecessary and slow ciphers from lib/silccrypt.
6307 * Set SO_KEEPALIVE option to connection sockets by default.
6309 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6311 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6312 redefined the Notify Payload into protocol specs.
6314 * Added silc_id_payload_parse_id to get ID directly from raw
6317 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6319 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6320 accept searching by Client ID as well.
6322 * Added support for LEAVE and SIGNOFF notify types in client library.
6324 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6325 to parse ID Payload from raw data.
6327 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Added flags parameter into silc_ske_assemble_security_properties
6330 function in lib/silcske/silcske.[ch].
6332 * Changed notify client operation to fit better for notify messages
6333 sent by server. The notify payload received from server is now
6334 passed to the application (after parsing it to SilcNotifyPayload).
6335 It is application's responsibility to retrieve the arguments
6336 from the payload and show the message the way it wants. The message
6337 sent by server is implementation specific.
6339 * Changed public keys to comply with the protocol specification.
6340 Old public keys are not supported anymore and are not compatible.
6342 * Removed nickname from Channel Payload as the latest draft removed
6343 it. The client must resolve the nickname from the NAMES command
6344 reply received when it joined the channel.
6346 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6348 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Fixed some errors in protocol specification drafts.
6352 * Created lib/silccore/silcnotify.c to implement Notify Payload
6353 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6354 generic payloads described by protocol specifications. The file
6355 includes implementations for ID Payload and Argument Payload.
6357 * Changed Command Payload implementation to use the new Argument
6358 Payload. Changed command_xxxx_payload to command_payload_xxxx
6359 to comply with SILC coding conventions.
6361 * Added suppport for Argument Payload handling in Notify Payload
6362 implementation as protocol requires it. Added the new support
6363 into server and client lib as well.
6365 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Added support for multiple nicknames on same channel. [n] is
6368 added locally to the nickname if there are more than one same
6369 nicknames on the channel.
6371 * Server now sends all nicknames that matched WHOIS request.
6372 Client also shows the list received from server.
6374 * Added TOPIC command to client side. User can now set and show
6375 current topic on channel.
6377 * Added MOTD command to client and server. Also, server sends the
6378 motd when client connects to the server.
6380 * Changed version strings to comply ISO 8601.
6382 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6384 * Fixed protocol error handling in client library. It should now
6385 cope even if the SKE fails for some reason.
6387 * Made new protocol specification drafts for submitting to IETF.
6389 * Implemented TOPIC command to server in silcd/command.c.
6391 * Added two new notify types into lib/silccore/silcnotify.h:
6392 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6393 notify nickname change and topic setting/change on a channel.
6395 * API change of command_reply operation in client library. The
6396 application gets now the status type received from server as well.
6398 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6402 * Cras fixed and optimized the packet handling even further and
6403 it should work now. Minor change to the prototype of function
6404 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6406 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6408 * Added new function into lib/silcutil/silcschedule.[ch]:
6409 silc_schedule_with_fd to select() a specified fd. The function
6410 returns after timeout expires or data arrives or goes. The
6411 function is used by packet routines to wait that all data is
6412 received from network.
6414 * Fixed data reading from network in lib/silccore/silcpacket.c.
6415 The code now assures that all data is read from the fd and then
6416 continues packet processing. This was a bug fix since the code
6417 used to drop some data in some circumstances.
6419 * Added new function into lib/silcclient/client.[ch]:
6420 silc_client_start_key_exchange to start key exchange after
6421 connection has been established to server. The code internally
6422 now uses this funtion but its main purpose was to provide it
6423 for applications that perform their own connecting. After
6424 application has created a connection it merely calls this
6425 function to start the key exchange between client and server.
6426 The library takes care of everything else after that.
6428 Updated also lib/silcclient/README to explain the usage of
6431 * Do not send to application information that connection has
6432 been established. Application gets notified it by connect
6435 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6437 * Applied cras's patch to add silc_schedule_one function. The
6438 function runs scheduler once and returns.
6440 * Fixed the scheduler after cras messed it up. The timeout
6441 handling works now as it's supposed to work.
6443 * Added into lib/silccore/ silcnotify.h to include notify
6444 message types support. Changed silc_server_send_notify*
6445 functions, in server.[ch], to support those new notify types.
6446 Added the support for the notify types into client library,
6447 as well. Added new notify client operation into ops.h in
6450 * Changed silc_server_packet_send_to_channel to send normal
6451 packets instead of just channel message packets. The function
6452 is now used to send the notify packets to channels. It is not
6453 used to send channel message packets anymore, as server never
6456 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6457 va_arg()s as it seems to require it nowadays. I guess, if SILC
6458 is compiled with older va_arg() the new code should work anyway.
6460 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6462 * Splitted core library. Core library (lib/silccore) includes
6463 now only SILC protocol specific core (and common) components.
6464 Created new utility library (lib/silcutil) that includes more
6465 generic purpose stuff. The stuff for util library was taken
6466 from the old core library. This was minor and easy split.
6468 * Created SILC Client Library (lib/silcclient) that includes
6469 implementation of the SILC client without user interface. This
6470 was major move from silc/ directory. The code has been changed
6471 so that it is transparent towards the user interface. The
6472 silc/ directory includes now the same user interface as before
6473 and it uses the new client library. Read lib/silcclient/README.
6474 Basicly, the client library performs everything else related
6475 to SILC except user interface handling. Also, configuration
6476 files are considered to be part of user interface and library
6477 does not handle them.
6479 This change also changed a lot of structures, function naming etc.
6480 Most important change was that SilcClientWindow object was
6481 renamed to SilcClientConnection in the client library. Created
6482 also new file lib/silcclient/ops.h. Also added new files
6483 silc/local_command.[ch] and silc/client_ops.[ch].
6485 All these changes were made to make it easier for user interface
6486 designers to create what ever user interface for the SILC client
6489 It is also expected that the server will be moved to lib
6490 directory as well and SILC Server Library will be created;
6491 sometimes in the future.
6493 * Removed Local commands from lib/silccore/silccommand.h as
6494 they are application specific and new client library does not
6495 handle any of those anymore.
6497 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6498 old client implementation in silc/.
6500 * Added support for callback functions in SILC_LOG_* macros.
6501 Application can now set its own callbacks that will be called
6502 instead of using the default functions that will always print
6503 the debug messages to stderr (or stdout). Also, debugging can
6504 now be disabled by setting silc_debug to FALSE and re-enabled by
6505 setting it to TRUE. Note, that logging will still work even
6506 if debugging is disabled.
6508 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6509 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6510 silc_log_reset_debug_callbacks.
6512 * To enable debugging in silc client one must give now -d
6513 option on command line.
6515 * Changed silc_schedule_init to automatically allocate task queues
6516 if they are not allocated before calling it.
6518 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6520 * Added GMP 3.1 into math library.
6522 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6524 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6525 a channel in SILC network. The packet is used by servers and
6526 routers to notify other routers that user has left a channel.
6527 This little feature was missing until now. Added the feature
6528 to protocol specification as well.
6530 Added functions: silc_server_send_remove_channel_user and
6531 silc_server_remove_channel_user into server.[ch].
6533 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6534 lib/silccore/silcpacket.h. However, they are not implemented
6537 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6539 * Fixed joining to a channel and sending channel messages
6540 between server and router. The channel message sending should
6541 now work inside a cell.
6543 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Fixed the private message sending between server and router.
6546 The private message sending should now work inside a cell.
6548 * Added silc_server_replace_id into server.[ch] to replace
6549 existing ID in the SILC network.
6551 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6552 and silc_idlist_replace_server_id into idlist.[ch] in server.
6554 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Fixed the server to server connections. Server can again now
6557 connect to router. Router to router connections probably does
6560 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6562 * Added dynamic protocol registering support. Now protocols can
6563 registered and unregistered on the fly. Patch by cras.
6565 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6567 * Added lib/contrib directory to hold routines that some platforms
6568 don't have but are needed by SILC.
6570 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6571 into lin/contrib to provide getopt() and getopt_long() for
6572 those who don't have it.
6574 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6576 * Added AWAY command to client. When away message is set and
6577 client receives a private message packet the client automatically
6578 replies to the sender with the away message.
6580 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6581 bug seemed to be the cause of recent problems when compiling
6584 * Added version detection support to SKE protocol specification
6585 and added the new changes to the SKE implementation as well.
6586 There were other minor changes in the SKE protocol as well.
6588 Many changes in lib/silcske/silcske.[ch] and in
6589 lib/silcske/payload.[ch].
6591 * Added ^U functionality, clear input line. Patch from cras.
6593 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Mainly small bugfixes on core library. Fixed some debugging
6596 logging and buffer overflow in silclog.c.
6598 * Updated config.sub and config.guess on the distribution tree.
6600 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * Added command lagging support in server. Client may execute
6603 commands now only once in two seconds.
6605 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6607 * Optimized packet reception. MAC computation and checking is now
6608 also more optimized. A lot previously duplicated code is now
6609 used as generic by both client and server.
6611 * Fixed key pair generation in clientutil.c
6613 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Added into lib/silccore/silcbufutil.[ch] new function;
6616 silc_buffer_realloc.
6618 * Moved generic packet sending/encryption functions to
6619 lib/silccore/silcpacket.[ch] from client and server. Some
6620 rewriting of the functions.
6622 * Moved all generic packet reception/decryption functions to
6623 lib/silccore/silcpacket.[ch] from client and server. The
6624 packet processing is now much cleaner in both client and server.
6625 These were major changes in both client and server.
6627 * Created many common functions in server to do packet sending.
6628 Previously code were duplicated a lot, this has been removed
6631 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Rewrote major parts of the ID cache system. Don't know
6634 whether it is better now or not but at least the API is more
6637 * Major rewrite on ID cache stuff on client because of the ID
6638 cache API changes. Added idlist.c to client.
6640 * Also major rewrite on ID cache stuff on server as well.
6641 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6642 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6643 in hand, instead they are all put into the ID cache system now.
6644 All server_idlist_* routines uses ID cache now instead of
6645 traversing its own lists (those lists does not exist anymore).
6646 SilcIDList though still exists. Also, SilcXXXEntry's are
6649 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Finally made the SKE implementation compliant to the protocol
6652 specification. All mp integers are now binary encoded as
6653 opposed being HEX encoded.
6655 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6658 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6659 functions: silc_[encode/decode]_pem. Also added function
6660 silc_encode_pem_file to PEM encode with newlines ('\n') for
6663 * SILC public keys are now encoded either PEM or binary. Same
6664 option is for private keys as well. By default private keys
6665 are binary encoded and public keys PEM encoded. Silly HEX
6666 encoding were removed.
6668 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6669 function to create fingerprints.
6671 * Fixed a bug in SHA1; does not change the original data anymore.
6673 * Partly implemented INFO command on client and server side.
6674 Fixed CLEAR command. Changes to SERVER command; show current
6675 server(s) when giving command without arguments. Added
6676 VERSION command to client.
6678 * Added check to server that unregistered connections cannot
6679 execute commands (unless it is specificly allowed).
6681 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6683 * Fixed screen refresh.
6685 * Fixed channel joining bug from client. On some circumstances
6686 client tried to join to a channel it had already joined.
6688 * Added public key verification process into client's protocol.c.
6689 The client now verifies the public key from user and saves
6690 it into ~./silc/serverkeys/ directory.
6692 Added into: clientutil.[ch]: silc_client_verify_server_key.
6694 * Changed SKE protocol's silc_ske_initiator_finish function
6695 to accept callback function that verifies the received public
6696 key. Removed old silc_ske_verify_public_key function.
6698 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6701 silc_pkcs_private_key[_data]_set.
6703 * Made the password and public authentication more cleaner in
6704 server's protocol.c.
6706 * Removed historic and obsolete protocol `channel_auth' from
6707 both client and server.
6709 * Removed wrong way of sending command status messages from
6710 server to client in server's command.c. The old way violated
6711 protocol specification.
6713 Changes to silccore/silccommand.[ch]: removed
6714 silc_command_encode_status_payload -> not needed anymore,
6715 changed silc_command_encode_payload_va to accept extra
6716 argument on variable argument list. The argument type must
6717 now be provided to the function. Also, added new function:
6718 silc_command_encode_reply_payload_va which is same as
6719 normal command_encode_payload_va except command status type
6720 is provided as extra argument.
6722 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6724 * Added ~./silc directory handling. The directory includes the
6725 public and private keys for the client.
6727 Added silc_client_check_silc_dir, silc_client_create_identifier
6728 and silc_client_load_keys.
6730 * Implemented SILC protocol compliant public key. Added public
6731 and private key saving to and loading from files.
6733 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6734 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6735 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6736 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6737 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6739 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6740 silc_pkcs_load_[public/private]_key.
6742 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6744 * Added silc_server_get_route (route.[ch]) to get connection
6745 data for the fastest route for given ID.
6747 * Implemented INVITE command on client and server. The command
6748 were re-defined in the SILC Protocol Specification and the
6749 implementation now complies with the specification.
6751 * Implemented PING command on client and server.
6753 * Implemented NAMES command on client and server. The server side
6754 supports currently only normal server not router server yet.
6755 Some changes to NAMES definition in SILC protocol specification.
6757 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6759 * Implemented LEAVE command on client and server.
6761 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6762 again. This change was made to the protocol as well. Server
6763 should not violate the protocol specification anymore.
6765 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6767 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6768 was tested. SOCKS4 was not but should work anyway.
