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

673 to run server on foreground. A patch by debolaz.
674 Affected files silcd/server.c, silcd/silcd.c.
676 * Fixed MOTD to return the MOTD file server name. Affected
677 file silcd/command.c.
679 * Added INFO command reply handling to the Irssi SILC Client.
680 Affected file irssi/src/silc/core/client_ops.c.
682 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
684 * Fixed the silc_idcache_list_* routines to really support
685 the dynamic list. Fixes a crash. Affected file is
686 lib/silccore/silcidcache.c.
688 * Fixed the LIST command reply to really call LIST command's
689 pending callbacks. Affected file silcd/command_reply.c.
691 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
693 * Update conn->local_entry->nickname after giving NICK
694 command. Affected file lib/silcclient/command.c.
696 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
698 * Added the [pid] option to the silcd configuration file
700 Affected files: serverconfig.[ch] and silcd.c
702 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Save fingerprint in WHOIS command reply in server.
705 Affected file silcd/command_reply.c.
707 * Fixed NICK commands pending callback registration.
708 Affected file lib/silcclient/command.c.
710 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
712 * Use ++server->cmd_ident when sending commands in server,
713 instead of random number. Affected file silcd/command.c.
715 * Fixed GETKEY command reply to call actually GETKEY pending
716 command callbacks. Affected file silcd/command_reply.c.
718 * A bit stricter check for nicknames. Check for same nickname
719 in NICK command also. Affected file silcd/command.c.
721 * Do not call INFO command everytime client ID changes, only
722 during first connecting. Affected file lib/silcclient/client.c.
724 * Set the new nickname only after successful command reply for
725 NICK command is returned by server. Affected file
726 lib/silcclient/command.c.
728 * Remove nicknames from nicklist during server_signoff notify.
729 Should fix /NAMES bit more. The affected file is
730 irssi/src/silc/core/silc-channels.c.
732 * Added `fingerprint' field to the SilcIDListData in the
733 silcd/idlist.h to hold the fingerprint of the client's
736 Send the fingerprint of the client's public key in WHOIS
739 Affected files silcd/command.c, and silcd/idlist.[ch].
741 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
742 create fingerprint from given data.
744 * Show the fingerprint of the client's public key in WHOIS.
745 Affected files irssi/src/module-formats.[ch] and
746 irssi/src/silc/core/client_ops.c.
748 * Format the multiple same nicknames also during JOIN and
749 NICK_CHANGE notifys. Affected file is
750 lib/silcclient/client_notify.c.
752 * Do not print error on screen for invalid private message
753 payload since it can come if someone is sending private
754 messages with wrong key. Affected file
755 lib/silccore/silcprivate.c.
757 * Fixed multiple concurrent /PING crash. Affected file
758 lib/silcclient/command.c.
760 * Changed the wrong ID encoding. All IP addresses must be
761 in MSB first order in encoded format. They were encoded
762 wrong and was in LSB format. Affected files are
763 silcd/serverid.c, lib/silcutil/silcutil.c.
765 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
767 * Call the `connect' client operation through the scheduler
768 in case of error. Affected file lib/silcclient/client.c.
770 * Call the `failure' client operation even if the error
771 occurred locally during a protocol. Affected file is
772 lib/silcclient/protocol.c.
774 * Added support of sending LIST command to router from normal
775 server. This way normal server can get list of all channels
776 in the network too. Fixed the channel list sending in the
777 server too. Affected files are silcd/command.c, and
778 silcd/command_reply.[ch].
780 * Added silc_server_update_channels_by_server and
781 silc_server_remove_channels_by_server. They are used during
782 disconnection of primary router and in backup router protocol.
783 Affected file silcd/server_util.[ch], silcd/server.c and
784 silcd/server_backup.c.
786 * Fixed channel adding to global list in IDENTIFY command
787 reply in server. Affected file silcd/command_reply.c.
789 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
791 * If the incoming packet type is REKEY or REKEY_DONE process
792 that packet always synchronously. Fixes yet another MAC
793 failed error on slow (dialup) connections. Affected file
794 lib/silcclient/client.c and silcd/server.c.
796 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
798 * Call check_version SKE callback for initiator too. Affected
799 file lib/silcske/silcske.c.
801 * Implemented fix for security hole found in the SKE that was
802 fixed in the specification few days back; the initiator's
803 public key is now added to the HASH value computation.
804 Added backwards support for the old way of doing it too, for
805 old clients and old servers. Affected file is
806 lib/silcske/silcske.c.
808 * Enabled mutual authentication by default in SKE. If initiator
809 is not providing mutual authentication the responder will
810 force it. This will provide the proof of posession of the
811 private key for responder. The affected files are
812 lib/silcclient/protocol.c and silcd/protocol.c.
814 * Do not cache anymore the server's public key during SKE.
815 We do mutual authentication so the proof of posession of
816 private key is done, and if the server is authenticated in
817 conn auth protocol with public key we must have the public
818 key already. Affected file silcd/protocol.c.
820 * Added new global debug variable: silc_debug_hexdump. If
821 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
822 file lib/silcutil/silclog.[ch].
824 * Fixed compilation warning due to char * -> const char *.
825 Affected files lib/silcutil/silcnet.h, and
826 lib/silccore/silcauth.[ch].
828 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
830 * Fixed CMODE command when new channel key was created. If
831 the creation failed the old key was removed. Next time giving
832 same command would crash the server since the old key was
833 freed already. Affected file silcd/command.c.
835 * Fixed the silc_server_announce_get_channels to not crash
836 on reconnect. Affected file silcd/server.c.
838 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
840 * Added silc_log_set_debug_string function to set a regex
841 string to match for debug output. Only the function names,
842 or filenames matching the given debug string is actually
843 printed. This way it is possible to filter out those debug
844 strings that user is not interested in.
846 Fixed a bug in silc_string_regexify.
848 Affected files lib/silcutil/silclog.[ch], and
849 lib/silcutil/unix/silcunixutil.c.
851 * Changed the -d options in both server and Irssi SILC client
852 to take the debug string as argument. Affected files
853 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
855 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
857 * Added silc_hash_babbleprint to create a Bubble Babble
858 Encoded fingerprint. The encoding is developed by Antti
859 Huima (draft-huima-babble-01.txt), and it creates human
860 readable strings out of binary data. Affected file
861 lib/silccrypt/silchash.[ch].
863 * Print the babble print now in addition of fingerprint as well
864 in Irssi SILC client. Affected files are
865 irssi/src/fe-common/silc/module-formats.[ch],
866 irssi/src/fe-common/silc/core/client_ops.c.
868 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
870 * Fixed a security problem found in SKE. The initiator's
871 public key too is now added to the HASH hash value creation
872 which is signed by the responder to create the SIGN value.
873 This will prevent anyone in the middle to lie to the responder
874 about the initiator's public key. If this is done now, the
875 man in the middle will get caught. Updated the protocol
878 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
880 * Better installation directory handling. Configure module
881 paths and other paths automatically to example_silc* files
882 in doc/. A patch by toma.
884 * Fixed compiler warning from MPI library, and from SILC RNG.
887 * Added SILC_SERVER_PID_FILE to define the pid file for server.
888 It can be configured with ./configure. A patch by toma.
890 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
892 * Find correct make to use in prepare-clean. A patch by
893 toma. Affected file prepare-clean.
895 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
897 * Added irssi variables use_auto_addr, auto_bind_ip,
898 auto_bind_port and auto_public_ip.
900 * Changed the interface for silc_client_send_key_agreement
901 in lib/silcclient/silcapi.h
905 irssi/src/silc/core/silc-core.c
907 lib/silcclient/silcapi.h
908 irssi/src/silc/core/silc-channels.c
909 lib/silcclient/client_keyagr.c
912 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
914 * Added silc_pkcs_public_key_compare to compare two
915 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
917 * Check that the client who set the founder mode on the
918 channel is the same client that is giving the founder
919 mode to itself. It is done by comparing the saved public
920 key (it is saved even in the authentication is passphrase).
921 Affected file silcd/command.c.
923 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
925 * Do not process packet for disconnected socket connection.
926 Affected file lib/silccore/silcpacket.c.
928 * Process the DISCONNECT packet through scheduler in the
929 client library. Affected file lib/silcclient/client.c.
931 * Fixed the silc_client_packet_parse to not to increase
932 the packet sequence number if the conn->sock and the
933 current socket connection is not same. This can happen
934 for example during key agreement when the conn includes
935 multiple socket connections (listeners). Affected file
936 lib/silcclient/client.c.
938 * The sender of the file transfer request now provides also
939 the pointer (listener) for the key exchange protocol. If
940 the listener cannot be created then it sends empty key
941 agreement and lets the receiver provide the listener.
943 Added `local_ip' and `local_port' arguments to the
944 silc_client_file_send. If they are provided they are used,
945 if not then it will attempt to find local IP address, if
946 not found or bind fails then the remote client will provide
949 Affected files are lib/silcclient/client_ftp.c and
950 lib/silcclient/silcapi.h.
952 * Extended the FILE SEND command to support defining the
953 local IP and port for key exchange listener. They are
954 optional. Affected file irssi/src/silc/core/silc-servers.c.
956 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
958 * Defined to WHOIS command reply the sending of fingerprint
959 of the client's public key (if the proof of posession of the
960 corresponding private key is verified by the server).
961 Updated to the protocol specification.
963 * Added support of receiving the client's public key's
964 fingerprint in command reply in client library. Affected
965 file is lib/silcclient/command_reply.c, and
966 lib/silcclient/idlist.[ch].
968 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
970 * Do not send over 128 chars long nickname to the server
971 in NICK command. Affected file lib/silcclient/command.c.
973 * Do not send over 256 chars long channel names to the server
974 in JOIN command. Affected file lib/silcclient/command.c.
976 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
978 * Assure that silc_server_close_connection cannot be called
979 twice for same socket context. Affected file is
982 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
984 * Send error message to application if opening file for
985 writing during file transfer fails. Affected file is
986 lib/silcclient/client_ftp.c.
988 Remove all file transfer sessions for a client that we're
989 removing from ID cache.
991 Affected file is lib/silcclient/client_ftp.c.
993 * Fixed silc_net_addr2bin to return correct address. Affected
994 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
996 * Fixed file transfer session removing on signoff notify.
997 Affected file irssi/src/silc/core/silc-servers.c.
999 * Added the SilcClientFileError to be returned in the monitor
1000 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1001 Affected file lib/silcclient/silcapi.h.
1003 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1005 * Fixed a crash in silc_client_ftp_free_sessions and
1006 silc_client_ftp_session_free_client. Affected file
1007 lib/silcclient/client_ftp.c.
1009 * Added `disabled' field in the SilcChannelEntry in the server
1010 to indicate if the server entry is disabled. Affected file
1011 silcd/idlist.h, silcd/command[_reply].c.
1013 * SILC server adds now /var/run/silcd.pid everytime it is
1014 started. Affected file silcd/silcd.c.
1016 * Added silc_server_packet_send_clients to send a packet to
1017 the provided table of client entries. Affected file
1018 silcd/packet_send.[ch].
1020 * Fixed a crash in client resolving in client_prvmsg.c in
1021 client library. Affected file lib/silcclient/client_prvmsg.c.
1023 * Do not actually remove the client directly from ID cache
1024 during SERVER_SIGNOFF, but invalidate it. This way we
1025 preserve the WHOWAS info for the client. Affected file
1026 silcd/server_util.c.
1028 * Fixed SERVER_SIGNOFF notify handling in the server. The
1029 server is now able to process incoming SERVER_SIGNOFF notify
1030 for a server that it doesn't even know about. It will remove
1031 the clients provided in the notify. Affected file
1032 silcd/packet_receive.c.
1034 * Check for partial packet in data queue after every packet that
1035 was found from the queue. Return and wait for more data if
1036 there is partial data in queue. Affected file is
1037 lib/silccore/silcpacket.c.
1039 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Added SilcClietFileError enum to indicate error in
1042 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1043 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1044 Affected files lib/silcclient/silcapi.h and
1045 lib/silcclient/client_ftp.c.
1047 * Check that newsize in silc_buffer_realloc is larger than
1048 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1050 * Added better monitor of file transfers. It now monitors
1051 key agreement protocol during the file transfer too. Added
1052 error reporting too. Affected files
1053 irssi/src/silc/core/silc-servers.c,
1054 irssi/src/fe-common/silc/module-formats.[ch].
1056 * Wrote a help file for FILE command.
1058 * Added silc_rng_global_get_byte_fast to get not-so-secure
1059 random data as fast as possible. Random data is read from
1060 /dev/urandom if available and from the SILC RNG if not
1061 available. It is used in padding generation. Affected file
1062 lib/silccrypt/silcrng.[ch].
1064 * All packets in client library are now processed synchronously.
1065 Optimized packet processing a lot. Affected file
1066 lib/silcclient/client.c.
1068 * All server connection packets are processing synchronously
1069 now in server, to optimize packet processing. Affected file
1072 * Include files are installed now only in Toolkit distribution
1073 if make install is given. Affected files: all Makefile.am's.
1075 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1077 * Assure that silc_client_notify_by_server_resolve does not
1078 resolve the client information multiple times. If it cannot
1079 be found by the first it cannot be found at all. Affected
1080 file lib/silcclient/client_notify.c.
1082 * Fixed WHOWAS command reply calling. Affected file
1083 lib/silcclient/command_reply.c.
1085 * Removed all references to silc_idlist_get_client from the
1086 Irssi SILC client since that call is internal call used by
1087 the library. The Irssi SILC client will use now client
1088 retrieval functions found in silcapi.h.
1090 * Fixed a bug in resolving nickname info before sending
1091 private message. It used freed memory. Affected file
1092 irssi/src/silc/core/silc-servers.c.
1094 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1096 * Assure my_channels statistics cannot go negative in server.
1097 Affected files silcd/server.c, silcd/server_util.c.
1099 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1103 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Win32 Toolkit changes. Affected files
1106 win32/silc.dsw, win32/libsilc/libsilc.def,
1107 win32/libsilcclient/libsilc.def,
1108 lib/silcutil/silcutil.c, and
1109 lib/sftp/sftp_fs_memory.c.
1111 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1113 * Added silc_net_localip to return local host's IP address.
1114 Affected file lib/silcutil/silcnet.[ch].
1116 * If key exchange or rekey protocol is active for a connection
1117 parse all packets syncronously since there might be packets
1118 in packet queue that we are not able to process without first
1119 processing packets before them. Affected file silcd/server,
1120 lib/silcclient/client.c.
1122 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1123 whether library should continue processing the packet.
1124 Affected file lib/silccore/silcpacket.h.
1126 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1127 SilcSFTPMonitorData to SFTP server to monitor various

1155 lib/silcutil/silcutil.[ch].
1157 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1159 * Resolve the client info when received private message or
1160 channel message for a client which nickname we don't know.
1161 Affected files lib/silcclient/client_prvmsg.c and
1162 lib/silcclient/client_channel.c.
1164 * Do not crash in /KEY if client is not connected. Affected
1165 file irssi/src/silc/core/silc-channels.c.
1167 * Added SilcClientStatus field to the SilcClientEntry in the

1170 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1171 is incomplete and is being resolved, it won't be resolved
1174 Make sure also that USERS command reply does not resolve
1175 twice information. Affected file is
1176 lib/silcclient/command_reply.c.
1178 Make sure that silc_client_get_clients_by_list does not
1179 resolve twice same information.
1181 * Check for valid client->id in the silc_server_free_client_data.
1182 Affected file silcd/server.c.
1184 * Fixed /GETKEY nick@server not to crash if the server entry
1185 is not found. Affected file lib/silcclient/command.c.
1187 * Fixed the silc_server_check_cmode_rights to check the
1188 requested modes correctly. Affected file silcd/command.c.
1190 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Better checks for non-printable chars in nick added.
1193 Affected file silcd/command.c.
1195 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Call the silc_server_udpate_servers_by_server in the
1198 primary router that comes back online in the backup resuming
1199 protocol. Otherwise it routes packets wrong. Affected file
1200 silcd/server_util.[ch], silcd/server_backup.c.
1202 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1205 lib/silcutil/silcbuffmt.[ch].
1207 * Redefined the SILC packet header to include the padding
1208 length. Affected file lib/silccore/silcpacket.[ch].
1210 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1211 length for maximum padding up to 128 bytes). Affected
1212 file lib/silccore/silcpacket.h.
1214 * Removed all backwards support for old 0.5.x MAC thingies.
1215 The SILC packet header change makes it impossible to be
1216 backwards compatible.
1218 * Send the ENDING packet with timeout in the backup resuming
1219 protocol. This is to assure that all routers has connected
1220 to the primary router. Affected file silcd/server_backup.c.
1222 * Changed the RNG to take the first IV from random data. It
1223 used to take it from zero actually. Changed the RNG also
1224 to use /dev/urandom during session. /dev/random is used
1225 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1227 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1229 * Changed the SILC packet header to have the first two bytes
1230 (the packet length) encrypted. Affected files aroung the
1231 code tree, lib/silccore/silcpacket.[ch]. Removed the
1232 SilcPacketCheckDecrypt callback. It is not needed anymore
1233 since the silc_packet_receive_process will determine now
1234 whether the packet is normal or special.
1236 * Implemented the unidirectional MAC keys. Affected files
1237 lib/silcske/silcske.c, silcd/protocol.c and
1238 lib/silcclient/protocol.c.
1240 * Implemented the packet sequence number to the MAC computation.
1241 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1242 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1243 lib/silcclient/protocol.c.
1245 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1247 * Allow backup router to announce servers. All servers
1248 announced by backup router are added to the global list
1249 automatically. Update hte server's socket to our primary
1250 router also when backup router announces a server.
1251 Affected file silcd/packet_receive.c.
1253 * Do not update the client->router in the function
1254 silc_server_udpate_clients_by_server if the client is on
1255 global list. We might fail to find any specific server
1256 for locally connected clients and local cell clients. They
1257 should still use the `from' and not `to' as client->router.
1258 This fixes backup router resuming protocol. Affected file
1259 silcd/server_util.c.
1261 * Decrease channel statistics count only if the channel
1262 deletion worked. Affected files are silcd/server.c and
1263 silcd/server_util.c.
1265 * Added silc_server_update_servers_by_server to update origin
1266 of all server entries. Used during backup router protocol.
1267 Affected files silcd/server_util.[ch], silcd/server.c. and
1268 silcd/backup_router.c.
1270 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1271 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1272 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1273 lib/silccrypt/silchmac.c.
1275 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Assure that router cannot reroute the same channel message
1278 to the sender. Affected file silcd/packet_receive.c.
1280 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1282 * Made better checks that the channel message is not sent
1283 to the router it came from. Affected file is
1284 silcd/packet_send.c. Fixed memory leak too.
1286 * Announce informations for incoming router connection, but
1287 only after checking if it is replaced by backup router.
1288 Affected file silcd/packet_receive.c.
1290 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1292 * Fixed the backup resuming protocol to work in multiple
1293 router environment. Affected file silcd/server_backup.c.
1295 * Route packet only to one router in the function
1296 silc_server_packet_send_to_channel. Affected file is
1297 silcd/packet_send.c.
1299 * Fixed silc_server_send_notify_dest to set the broadcast
1300 flag. Fixed the silc_server_send_notify_topic to actually
1301 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1302 Affected file silcd/packet_send.c.
1304 * Changed the SFTP Filesystem interface. Changed the
1305 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1306 the filesystem operation function. The SilcSFTPFilesystem
1307 is now a context that is allocated by all filesystem allocation
1308 functions and it already includes the operations structure
1309 and filesystem specific context. It is given as argument
1310 now to the silc_sftp_server_start. This made the interface
1311 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1312 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1314 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1316 * Changed the backup router adding and getting interfaces
1317 in the server. The router that will be replaced by the
1318 specified backup router is now sent as argument. Affected
1319 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1322 * Added silc_net_addr2bin_ne to return the binary form of
1323 the IP address in network byte order. Affected files
1324 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1326 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Check for existing server ID in silc_server_new_server
1329 and in silc_server_connect_to_router_final and remove the
1330 old entry if it exists. Affected file silcd/packet_receive.c,
1333 * Send the channel message always to only one router, either
1334 in upstream or downstream. Affected file is
1335 silcd/packet_send.c.
1337 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * Wrote the definition of the backup resuming protocol to the
1340 protocol specification.
1342 * Removed one redundant channel key generation from normal
1343 server during joining procedure. Removed one redundant
1344 channel key sending from server to router during joining
1345 procedure. Affected file silcd/command.c.
1347 * Made minor bugfixes to the backup router resuming protocol.
1348 Affected file silcd/server_backup.c, server.c.
1350 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Added --disable-asm configuration option. Affected files
1353 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1356 * Implemented the backup resuming protocol that is used to
1357 resume the primary router position in the cell after the
1358 primary router comes back online. Affected files
1359 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1360 and silcd/server_util.[ch].
1362 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Sleep two (2) seconds after sending QUIT command to server.
1365 Affected file lib/silcclient/command.c.
1367 * Assure that if outgoing data buffer is pending do not force
1368 send any data. Affected file silcd/packet_send.c.
1370 * Assure that if outgoing data buffer is pending do not force
1371 send any data. Affected file lib/silcclient/client.c.
1373 * Implemented the backup router support when the primary router
1374 goes down. The servers and routers can now use the backup
1375 router as new primary router without loosing connectivity.
1377 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1379 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1380 in the server to indicate disabled entry. All data read
1381 from the connection will be ignored and no data is sent
1382 for entry that is disabled. Affected files are
1383 silcd/idlist.h, silcd/server.c.
1385 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Created SFTP client and server test programs in the
1388 lib/silcsftp/tests directory.
1390 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Implemented memory filesystem (virtual filesystem) for
1393 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1396 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * Implemented the SFTP (SSH File Transfer Protocol) to the
1399 lib/silcsftp. It includes SFTP client and SFTP server
1402 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1404 * Moved lib/silccore/silcprotocol.[ch] to the
1405 lib/silcutil library.
1407 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1408 take variable argument list pointer as argument. Affected
1409 file lib/silcutil/silcbuffmt.[ch].
1411 * Added silc_buffer_set function that is used to set data
1412 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1413 Affected file lib/silcutil/silcbuffer.h.
1415 * Changed various routines in the core library to use the new
1416 silc_buffer_set instead of allocating new buffer only for
1419 * Added 64-bit value formatting and unformatting support to the
1420 silc_buffer_[un]format routines. Affected file is
1421 lib/silcutil/silcbuffmt.[ch].
1423 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1424 to includes/bitmove.h.
1426 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1428 * Fixed channel user mode saving in client library. Affected
1429 file lib/silcclient/command[_reply].c.
1431 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * Defined the file transfer to the SILC Protocol. Added
1434 new packet type SILC_PACKET_FTP and defined File Transfer
1435 Payload. The mandatory file transfer protocol is SFTP
1436 (SSH File Transfer Protocol). Affected file in addition
1437 of the internet draft is lib/silccore/silcpacket.h.
1439 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1440 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1441 is used as part of backup router protocol when the primary
1442 router of the cell is back online and wishes to resume
1443 the position as primary router.
1445 * Redefined the MAC generation keys in the protocol. The
1446 same key is not used anymore in both direction. Both
1447 direction will now use different keys for sending and
1448 receiving. This fixes a potential security flaw. This
1449 change causes incompatibilities in the protocol.
1451 * Redefined also the MAC computation from the packet.
1452 An packet sequence number is now added to the MAC
1453 computation. This prevents possible replay attacks against
1454 the protocol. This change too causes incompatibilities
1457 Added `sequence' field to the SilcPacketContext to hold
1458 the current sequence number for the packet.
1460 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Added `created' field to the SilcIDListData in the file
1463 silcd/idlist.h to indicate the time when the entry was
1466 * Added `created' field to the SilcChannelEntry too. Affected
1467 file silcd/idlist.h.
1469 * Added `creation_time' aguments to all the announcement functions
1470 in the server. If it is provided then only the entries that
1471 was created after the provided time frame are actually
1472 announced. Affected file silcd/server.[ch].
1474 * The protocol says that the Channel ID's IP address must be
1475 based on the router's IP address. Added check for this in
1476 the silc_server_new_channel when processing incoming New Channel
1477 Payload. Affected file silcd/packet_receive.c.
1479 * Print out the correct version with --version in SILC client.
1480 Affected file irssi/src/silc/core/silc-core.c.
1482 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1484 * Fixed WHOWAS command to check for completnes of the client
1485 entry always, not just when the command is coming from client.
1486 Affected file silcd/command.c.
1488 * Added new function silc_server_packet_queue_purge to purge the
1489 outgoing data queue to the network. After the function returns
1490 it is guaranteed that the outgoing packet queue is empty.
1491 Affected file silcd/packet_send.[ch].
1493 * Purge the outgoing packet queue in the rekey protocol's final
1494 callback to assure that all rekey packets go to the network
1495 before quitting the protocol. Affected file silcd/server.c.
1497 * Added silc_client_packet_queue_parse as similar function as
1498 in server to the client library. The affected file is
1499 lib/silcclient/client.c.
1501 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1503 * Splitted silcd/server.c and created silcd/server_util.[ch]
1504 for utility functions.
1506 * Added new socket flag SILC_SF_DISABLED to indicate that the
1507 connection is open but nothing can be sent to or received from
1508 the connection. Affected file lib/silcutil/silsockconn.[ch].
1509 The checking for disabled socket is checked in the low level
1510 silc_socket_write and silc_socket_read functions.
1512 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Allow only nicknames and channel names that fits into the
1515 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1517 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * When processing JOIN command reply in server check that if
1520 the channel exists in our global list we'll move it the local
1521 list. Affected file silcd/command_reply.c.
1523 * Fixed the check whether client is joined on the channel already
1524 in JOIN command. Affected file lib/silcclient/command.c.
1526 * Fixed the JOIN command reply to check whether the channel
1527 already exists. Affected file lib/silcclient/command_reply.c.
1529 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Added silc_ske_status_string to map the SKE error numbers
1532 to readable strings. The affected files are
1533 lib/silcske/silcske[_status].[ch].
1535 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * Do not show the private channels on the WHOIS channel list
1538 as it is not allowed by the protocol. The affected file is
1541 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Assure that the packet length digged from the actual packet
1544 is something sensible in the silc_packet_decrypt_rest_special
1545 in lib/silccrypt/silcpacket.c.
1547 * Free and NULL the allocated pointer in silc_hmac_alloc if
1548 the HMAC allocation fails. The affected file is
1549 lib/silccrypt/silchmac.c.
1551 * Print the selected security properties to the log files in
1552 the server. Affected file silcd/protocol.c.
1554 * Add SKE's reference counter even if calling the completion
1555 callback manually. Otherwise it goes negative, although it
1556 does not cause any problems. The affected file is
1557 lib/silcske/silcske.c.
1559 * Remove the client entry with short timeout after giving the
1560 KILL command. Affected file lib/silcclient/command.c.
1562 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1563 case all found clients are already disconnected (WHOWAS would
1564 found them) in the server. Affected file silcd/command.c.
1566 * Update the last_receive (time of last data received) to be
1567 updated only when received private or channel message so that
1568 the idle time showed in WHOIS makes more sense.
1570 * Added boolean field `valid' in to the SilcClientEntry in the
1571 client library to indicate whether the entry is valid or not.
1572 This fixes the nickname change bug on channel when changing
1573 the nickname to be same than the old (like nick to Nick) the
1574 nickname formatter doesn't set the new nick anymore to Nick@host.
1575 Affected file lib/silcclient/idlist.[ch].
1577 * Now actually fixed the nickname changing on disconnection.
1578 Added new function silc_change_nick to the Irssi SILC Client.
1579 Affected file irssi/src/silc/core/client_ops.c,
1580 irssi/src/silc/core/silc-nicklist.[ch].
1582 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Check that the public key exists in the GETKEY command before
1585 trying to encode it. Affected file silcd/command.c.
1587 * Print some notifications on received public keys with GETKEY
1588 command in the Irssi SILC Client. Affected files are
1589 irssi/src/fe-common/silc/module-formats.[ch],
1590 irssi/src/silc/core/client_ops.c.
1592 * Use IDENTIFY command to resolve the server information in the
1593 GETKEY command instead of INFO command. Affected file
1594 lib/silcclient/command.c.
1596 * All command reply functions in the client library now calls
1597 the pending command reply callbacks even if an error has
1598 occurred. The server has done this a long time and now it was
1599 time to move the client library to this as well. Now all
1600 errors can be delivered back to the pending command reply
1601 callbacks if necessary. Affected files are
1602 lib/silcclient/command[_reply].[ch].
1604 * Change the nickname on disconnection back to the username
1605 because in reconnect the server will enforce it to it anyway.
1606 Affected file irssi/src/silc/core/silc-servers.c.
1608 * Fixed a config file parsing bug in the Irssi SILC client.
1609 Affected file irssi/src/silc/core/clientconfig.c.
1611 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * When printing the channel mode on JOIN, verify that the
1614 channel key and channel's HMAC are valid. Affected file
1615 irssi/src/silc/core/client_ops.c.
1617 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1619 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1620 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1621 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1623 * Removed channel key rekey task deleting from the function
1624 silc_server_save_channel_key. Affected file silcd/server.c.
1625 Added explicit timeout task context instead that is used to
1626 delete the task if we are registering a new task before the
1627 new task has elapsed.
1629 * When channel key rekey occurs the client library now saves
1630 the old channel key for a short period of time (10 seconds) and
1631 is able to use it in case some is still sending channel
1632 messages encrypted with the old key after the rekey. Affected
1633 file lib/silcclient/[idlist.h|client_channel.c].
1635 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Added check to the silc_server_new_id_real to not accept
1638 new ID if it is the sender's own ID. Affected file is
1639 silcd/packet_receive.c.
1641 * Assure that we do not announce ourself or the one we've
1642 sending our announcements when we're router and are announcing
1643 servers to our primary router. Affected file silcd/server.c.
1645 * Fixed silc_server_command_identify_check_client to assemble
1646 correct WHOIS packet. It send corrupted WHOIS packet and
1647 caused problem with router to router connections. Affected
1648 file silcd/command.c.
1650 Fixed also silc_server_command_whois_check the same way
1651 as for the IDENTIFY command.
1653 * Added new SilcIDListStatus to the server in the SilcIDListData
1654 structure. The status now includes the current status of
1655 the entry (like registered, resolved etc.). Affected file
1656 silcd/idlist.[ch]. Defined a bunch of different status types
1657 as well. This replaced the old boolean registered field as well.
1659 Added resolve_cmd_ident field to the SilcClientEntry structure
1660 too so that if the entry is for example being resolved so
1661 another command may attach to the same pending command reply
1662 without requiring to resolve the same entry again. This concept
1663 should optimize the WHOIS and the IDENTIFY resolving under
1664 heavy load by taking away unnecessary resolving for entries
1665 that are being resolved already.
1667 Added support for adding multiple pending commands for one
1668 command idenfier. Affected file silcd/command[_reply].[ch].
1670 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1671 before deleting the data. Otherwise the hash table will have
1672 freed data in comparison functions. Affected file is
1673 silcd/command_reply.c.
1675 * Fixed silc_idlist_replace_client_id to add the new entry to
1676 the cache with NULL nickname. Otherwise there will be invalid
1677 memory as the nickname after the nickname is freed. Affected
1678 file silcd/packet_receive.c.
1680 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1681 saved into wrong slots because the previous number of entries
1682 was not taken into account. Affected file silcd/idlist.c.
1683 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1685 * If we are router and we receive JOIN notify to a channel that
1686 does not have any users then notified client is marked as the
1687 channel founder, as it is it. The affected file is
1688 silcd/packet_receive.c
1690 * Added to the extended hash table API's table_del_*ext functions
1691 the destructor as argument too, so that the caller can decide
1692 which destructor to use or whether to use destructor at all.
1693 Affected file lib/silcutil/silchashtable.[ch].
1695 * Fixed ID Cache purging. It actually deleted the entries from
1696 the hash table after the data was freed. The hash table ended
1697 up comparing freed memory. The affected file is
1698 lib/silccore/silcidcache.c.
1700 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1702 * Fixed Irssi SILC client's KILL command's HELP syntax.
1704 * The USERS command now resolves the detailed user information
1705 if the userinfo field is missing. Affected file is
1706 lib/silcclient/command_reply.c.
1708 * Do not print error in silc_file_read if the read file does
1709 not exist. Just silently return NULL. Affected file is
1710 lib/silcutil/silcutil.c.
1712 * Fixed the silc_log_output to not wine about NULL filename
1713 and to not create some bogus " " filename. Affected file is
1714 lib/silcutil/silclog.c.
1716 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Fixed various printing bugs on the user interface in the
1719 Irssi SILC Client. Minor changes that were forgotten from
1722 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Fixed the configure.in.pre and the compilation and distribution
1725 environment to support the new autoconf 2.52. That version is
1726 now required to compile the CVS trunk.
1728 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1730 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1731 to generally parse user@fqdn format strings. Affected file
1732 lib/silcutil/silcutil.c.
1734 * Added nickname_format and nickname_force_format fields to the
1735 SilcClientParams structure. The first one defines the format
1736 for the nicknames that the library will enforce if the receives
1737 multiple same nicknames. The second one is boolean value and
1738 can be used to force the library to always enforce the format
1739 to the nicknames regardles whether there are multiple nicknames
1740 or not. This configurable formatting was employed to flexibly
1741 support accessing multiple nicknames from the user interface.
1742 The userinterface can now set the nicknames to what ever format
1743 they prefer. Affected file lib/silcclient/silcapi.h.
1745 Added function silc_client_nickname_format to the file
1746 lib/silcclient/idlist.c. It performs the nickname formatting.
1748 Added new field `hostname´ to the SilcClientEntry context.
1749 It holds the hostname of the client. Affected file is
1750 lib/silcclient/idlist.h.
1752 * Irssi SILC Client sets the nicknames in nick@hostn format.
1753 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1754 irssi/src/silc/core/silc-core.c.
1756 The WHOIS printing now also shows both the real nickname and
1757 the formatted nickname so that user knows how to access the
1758 user if there are multiple same nicknames cached. Affected
1759 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1760 printing formatting too to take the hostname now as a separate
1761 argument. The Affected file is
1762 irssi/src/fe-common/silc/modules-formats.[ch].
1764 * Changed the silc_client_get_clients_local to accept the formatted
1765 nickname as argument. It accepts the real nickname too but the
1766 formatted nickname can be used to find the true entry from
1767 multiple entries. Affected file lib/silcclient/silcapi.h and
1768 lib/silcclient/idlist.c.
1770 * Added nickname_format_parse field to the SilcClientParams.
1771 It is a callback function provided by the application to parse
1772 the nickname out of the formatted nickname string. The library
1773 calls it to get the nickname from the formatted string. Since
1774 the application generally knows better the format of the nickname
1775 string it parses it instead of the library, even though library
1776 encodes the formatted string. If the callback function is not
1777 provided then the library will use the string as is. The
1778 affected file is lib/silcclient/silcapi.h.
1780 * All the nickname strings passed to the client library in
1781 commands are now expected to be formatted nickname strings.
1782 If the command does not support the formatted nickname string
1783 it will assume that the sent string is the actual nickname.
1784 Affected file lib/silcclient/command.c.
1786 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1788 * Added public key authentication support to OPER and SILCOPER
1789 commands in the client library. Affected file is
1790 lib/silcclient/command.c.
1792 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1794 * Changed the get_auth_methdod client operation to be asynchronous.
1795 It can be async if the application resolves the authentication
1796 method from the server during the negotiation. Added new
1797 SilcGetAuthMeth completion callback that the application will
1798 call after resolving the authentication method.
1800 Added function silc_client_request_authentication_method that
1801 the application can use to resolve the authentication method
1802 from the server. Added also SilcConnectionAuthRequest callback
1803 that the library will call after the server has replied. The
1804 application can call this function if it does not know the
1805 current authentication method.
1807 Affected files are lib/silcclient/client.c and
1808 lib/silcclient/silcapi.h.
1810 * The Irssi SILC client now automatically resolves the authentication
1811 method incase any configuration information is not present (and
1812 currently there never is). The affected file is
1813 irssi/src/silc/core/client_ops.c.
1815 * Fixed public key authentication from the client library.
1816 Affected file lib/silcclient/protocol.c. Changed also the
1817 protocol specification about the public key authentication in
1818 the connection authentication protocol. The actual data to be
1819 signed is now computed with a hash function before signing.
1821 * Fixed the public key authentication from the server as well.
1822 Affected file silcd/protocol.c.
1824 * Removed the mlock()'s from the memory allocation routines.
1825 Affected file lib/silcutil/silcmemory.c. The ./configure does
1826 not check anymore for the mlock(). Affected file is
1829 * Fixed USERS command in server to allow the execution of the
1830 command for private and secret channels if the client sending
1831 the command is on the channel. Affected file silcd/command.c.
1833 * Fixed silc_client_get_clients_local to return the clients
1834 count correctly. It could return wrong value. Affected file
1835 lib/silcclient/idlist.c.
1837 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1840 types. The assembler optimizations seemed not to like 64-bit
1841 data types. The assmebler optimizations thus are now enabled
1842 also for BSD systems as opposed to only enable them for Linux.
1844 * Do not check for threads at all on BSD systems. Affected
1845 file configure.in.pre.
1847 * Removed -n and -h options from the Irssi SILC Client since
1848 they are not used in silc.
1850 * Fixed the prime generation to assure that the first digit
1851 of the generated random number is not zero since our conversion
1852 routines does not like number strings that starts with zero
1853 digit. If zero digit is seen the random number is regenerated.
1854 This caused some corrupted RSA keys when the zero first digit
1855 was met. Affected file lib/silcmath/silcprimegen.c.
1857 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1859 * Fixed WIN32 configuration in the ./configure script.
1860 Fixed to include xti.h on environments that has it.
1861 Patches by Carsten Ilchmann and andrew.
1863 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Changed the silc_id_create_client_id to be collision
1866 resistant. It is now assured that there cannot be created
1867 two same client ID's. I suspect that some weird bugs in
1868 the server were actually caused by duplicate Client IDs.
1869 Affected file silcd/serverid.[ch]. A router receiving
1870 new ID now also assures and informs the sending server
1871 if the ID caused collision.
1873 * Changed the silc_id_create_channel_id to also assure that
1874 there are no collisions.
1876 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1878 * Statement about ignoring the Mutual Authentication flag when
1879 performing rekey with PFS was a bit misleading. It is ignored
1880 if it was set in the initial negotiation, it cannot be even
1881 set in the rekey. Fixed in the ke-auth draft. Started the
1882 new versions of the protocol drafts in the doc/.
1884 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Fixed a bug in silc_client_command_identify_save when saving
1887 new channel information. The channel name was no duplicated
1888 and caused crash on exit. Affected file is
1889 lib/silcclient/command_reply.c.
1891 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Fixed the getkey command handling in the server. Send just
1894 empty OK reply to the sender if the key could not be fetched
1895 (but everything else was ok, like the key just was not available).
1896 Changed the public key parameter to optional in the protocol
1897 specs so that empty OK reply can be sent. Affected file
1900 Added a message to Irssi SILC client to tell to user if the
1901 server did not return a public key.
1903 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * Fixed a channel key regeneration bug. It registered new
1906 timeout tasks exponentially until all system resources were
1907 used. Affected file silcd/server.c.
1909 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1911 * Added the SILC Document generator to the scripts/silcdoc.
1912 It can be used to generate the Toolkit Reference Manual out
1913 of the source tree. Internally it will also use the RoboDoc
1914 generator now imported in util/robodoc.
1916 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Added couple of return's in rekey protocol if error orccurred
1919 during the protocol. The execution must be terminated.
1920 Affected file silcd/protocol.c. Also, terminate the protocol
1921 always with timeout.
1923 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * The client's Client ID was created initally from the wrong
1926 nickname (it could have been in format nick@host) in the
1927 silc_server_new_client. Affected file silcd/packet_receive.c
1929 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Added some SILC_LOG_ERROR's to various error conditions
1932 if client could not be added to ID cache. Affected files
1933 silcd/packet_receive.c and silcd/server.c.
1935 * When client's sock->user_data is freed, NULL also the
1936 client->router and client->connection pointers. Added check
1937 for these pointers being NULL to various places around the
1938 code. Affected file silcd/server.c.
1940 * Added client->data.registered == TRUE checks to various
1941 places around the code to assure that unregistered client's
1942 are not handled when it is not allowed. Affected file
1945 * Added `bool registered' fields to all
1946 silc_idlist_[server|client]_get_* routines to indicate whether
1947 the fetched client needs to be registered or not. Affected
1948 file silcd/idlist.[ch].
1950 * Add your own entry as registered to the ID cache in the
1951 server. Affected file server.c.
1953 * Fixed a bug in silc_server_new_server. The SilcServer was
1954 set as the new server's context instead of SilcServerEntry.
1955 This naturally caused some weird bugs.
1957 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Do not delete the channel rekey task when adding it
1960 for in silc_server_create_channel_key.
1962 * Changed the silc_server_create_channel_key to return
1963 TRUE or FALSE to indicate the success of the channel key
1966 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1968 * Fixed MSVC++ project files and added missing files to
1969 Makefiles under win32/.
1971 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Do not add TCP_NODELAY flag if the operating system
1974 does not have it defined. Affected files are
1975 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1977 * Fixed buffer overflow from Irssi SILC Client. Affected
1978 file irssi/src/fe-common/core/themes.c.
1980 * Fixed double free in client library in the file
1981 lib/silcclient/client.c when disconnecting from server.
1983 * Applied double free patch from cras to Irssi SILC client.
1984 Affected files irssi/src/core/[modules/expandos].c
1986 * Fixed the disconnection handling to Irssi SILC Client.
1987 The application must call silc_client_close_connection
1988 in ops->connect client operation in case of failure of
1989 the connection. Affected file is
1990 irssi/src/silc/core/client_ops.c.
1992 * Do not set sock->protocol to NULL in the function
1993 silc_client_close_connection after executing the protocol's
1994 final callback since the sock might not be valid anymore.
1995 Affected file lib/silcclient/client.c.
1997 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1999 * Do not enable SILC_THREADS if the linking with libpthread
2000 did not happen. Affected file configure.in.pre.
2002 * Added notion to protocol specification that server must
2003 verify the sent authentication payload with CMODE when
2004 setting the channel founder key. Implemented it to the
2005 server. Affected file silcd/command.c.
2007 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Added _EXTRA_DIST SILC distribution variable to the
2010 distributions file. It is used to conditionally add extra
2011 files or directories to the specific distribution. Affected
2012 files ./prepare, Makefile.am.pre and distributions.
2014 Removed the `_' from the start of the distribution names.
2017 * Added README.WIN32 for instructions to compile the Toolkit
2020 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Fixed a double free in disconnection in the server. Affected
2023 file is silcd/server.c.
2025 * Fixed the lib/silcske/groups.c to work now also with GMP
2026 MP library. The string conversion did not work when using
2027 specific base and the base is indicated in the string as well.
2029 * Created win32/ directory which now includes MSVC++ specific
2030 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2031 It will appear only in the toolkit distribution
2033 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * Changed the key material distribution function in case when
2036 the hash output is too short. The data is now concatenated
2037 a bit differently than it used to. Made the change to the
2038 SKE protocol specification.
2040 * Added better GMP detection to configure.in.pre. A patch
2043 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Fixed a minor bug in SKE that might cause some problem on
2046 some platforms. Affected file lib/silcske/silcske.c.
2048 * Added the cookie checking for initiator in the SKE. It checks
2049 that the responder returns the sent cookie unmodified. The
2050 affected file is lib/silcske/silcske.c. Added new SKE
2051 error type INVALID_COOKIE that can be sent during the
2052 negotiation. Fixed some memory leaks as well.
2054 * Added the "invalid cookie" error message to Irssi SILC client's
2057 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2059 * Added `task_max' field to the SilcClientParams to indicate
2060 the maximum tasks the scheduler can handle. If set to zero,
2061 default values are used. Affected file lib/silcclient/silcapi.h.
2063 * Fixed memory leaks in silc_client_close_connection. Affected
2064 file lib/silcclient/client.c.
2066 * Added silc_client_del_client_entry to client library to free
2067 all memory of given client entry. Affected file is
2068 lib/silcclient/idlist.[ch].
2070 * Added new functions silc_client_del_channel and
2071 silc_client_del_server to delete channel and server entries.
2072 Affected file lib/silcclient/[silcapi.h/idlist.c].
2074 * Removed silc_client_del_client_by_id from silcapi.h.
2076 * Fixed the INFO command to return the server's own info
2077 correctly when querying by Server ID. Affected file is
2080 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2082 * Removed the non-blocking settings in WIN32 code in the
2083 silc_sock_[read/write] and added SleepEx instead. Affected
2084 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2085 of input data is now checked with FIONREAD and ioctlsocket.
2087 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2089 * Call silc_schedule_task_del_by_context in the
2090 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2091 Affected file lib/silccore/silcprotocol.c.
2093 * Call silc_protocol_cancel for active protocols in the
2094 silc_server_close_connection if the funtion
2095 silc_server_free_sock_user_data has not been called.
2096 Affected file silcd/server.c.
2098 * Generic tasks cannot be deleted using the del_by_fd
2099 task deleting function since generic tasks does not match
2100 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2102 * Added a notion to SILCOPER help file that the SILCOPER works
2103 only on router server, not on normal server.
2105 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2107 * Added for WIN32 support for the new scheduler as well.
2108 Affected file lib/silcutil/win32/silcwin32schedule.c.
2110 * Fixed the SHA1 implementation to work on various platforms.
2112 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2115 API. It is part of the scheduler now. Everything else is
2116 as previously but some functions has changed their names.
2117 Checkout the lib/silcutil/silcschedule.h for the interface.
2118 Updated all applications to use the new interface. Affected
2119 files are lib/silcutil/silcschedule.[ch].
2121 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2123 * Found a bug in the SKE implementation. The HASH value,
2124 specified by the protocol, was not computed correctly. The
2125 public key of the responder was not added to the computation
2126 even though it is mandatory. Affected file lib/silcske/silcske.c.
2127 This unfortunately causes incompatibilities with older
2128 clients and servers.
2130 * Added WIN32 specific network init and uninit functions:
2131 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2132 the Winsock2. Affected file lib/silcutil/silcnet.h and
2133 lib/silcutil/win32/silcwin32net.c.
2135 * Set the socket always to nonblocking mode on WIN32 after
2136 reading data or writing data. Affected file is
2137 lib/silcutil/win32/silcwin32sockconn.c.
2139 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2141 * Fixed various compilation problems under WIN32. Affected
2142 files lib/silcutil/win32/silcwin32thread.c and
2143 lib/silcutil/win32/silcwin32schedule.c.
2145 * Removed all _internal.h #includes from public header
2146 files. Internal headers must never be included from
2149 Removed also the lib/silcske/payload_internal.h file.
2151 * All include files that may be needed (public and some others
2152 included by the public headers) by application developers are
2153 now copied to the ./includes directory. It does not copy any
2154 internal headers. Affected file Makefile.defines.pre and all
2155 Makefile.am's under lib/ and subdirs.
2157 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2159 * Do not change the ~/.silc directory's permissions automatically.
2160 Affected file irssi/src/silc/core/clientutil.c.
2162 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2164 * Do not cancel the protocol in silc_server_close_connection
2165 it might cause recursion. Now cancelled in the function
2166 silc_server_free_sock_user_data. Affected file silcd/server.c.
2168 * Fixed the silc_server_remove_clients_by_server to regenerate
2169 the channel keys correctly finally. Added also new function
2170 silc_server_remove_clients_channels to actually do it.
2171 Affected file silcd/server.c.
2173 * Fixed the silc_server_new_channel to not crash by giving
2174 wrong router to the new channel. Affected file is
2175 silcd/packet_receive.c.
2177 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2180 which is given as argument to the silc_client_alloc now.
2181 It can be used to configure the client and set various parameters
2182 that affect the function of the client.
2184 * The USERS command in server did not check whether the channel
2185 is private or secret. Affected file silcd/command.c.
2187 * Added new argument to the USERS command in protocol specification.
2188 The USERS command now can take the channel name as argument
2189 as well. Added support for this in client and server and
2190 updated the protocol specs.
2192 * Completed the GETKEY command in client. It can be now used
2193 to fetch also servers public key not only some clients.
2194 Affected files lib/silcclient/command[_reply].c.
2196 * Added silc_client_get_server to return server entry by the
2197 server name. Affected files lib/silcclient/silcapi.h and
2200 * Redefined the IDENTIFY command in protocol specification to be
2201 more generic. It now can be used to query information about
2202 any entity in the SILC Network, including clients, servers and
2203 channels. The query may be based either the entity's name
2204 or the ID. Added support for this in both client and server.
2206 Affected files silcd/command.c and lib/silcclient/command.c
2207 and command_reply.c.
2209 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2210 the _from_client and _from_server functions. Affected file
2213 * Added silc_client_get_channel_by_id_resolve to the file
2214 lib/silcclient/silcapi.h to resolve channel information by
2215 its ID. Added also silc_client_get_channel_by_id that
2216 does not resolve it from the server.
2218 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2220 * Added SilcServerEntry context into the client library
2221 to represent one server. The INFO command now allocates
2222 these to save the resolved server info. For now on the
2223 client library will also keep information about servers,
2224 connected and resolved with INFO.
2226 The INFO command now allocates the SilcServerEntry context
2227 and saves the server info there. The COMMAND_REPLY in
2228 the INFO now returns the parameters to application in
2229 same order as defined in the protocol specification.
2231 The entries are cached in the client->server_cache.
2233 * The INFO command is now issued after received the Client ID
2234 from the server. Affected file lib/silcclient/client.c.
2236 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2237 to the application as the mode changer might be server.
2238 It is guaranteed that NULL is not returned anymore to the
2239 application. Affected file lib/silcclient/client_notify.c.
2241 The ID Type is now also passed to the application so that
2242 it can check whether the returned entry is SilcClientEntry
2245 Added new function silc_client_get_server_by_id to return
2246 the server entry by ID. Affected files are the
2247 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2249 * Do not create the channel in the Irssi SILC Client when issuing
2250 the JOIN command but when received the sucessful JOIN command
2251 reply. Otherwise the channel might get created even though we
2252 could not join it. The Affected file is
2253 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2255 * Fixed a channel joining bug in router. The router must also
2256 check the channel modes, invite and ban lists etc. when serving
2257 the JOIN command sent by normal server. Affected file is
2258 silcd/command.c. The router now resolves the client's
2259 information from the server who sent the JOIN command if it
2260 does not know it, and processes the JOIN command only after
2263 * Changed the SilcCommandCb to take new argument; void *context2.
2264 Affected file lib/silccore/silccommand.h
2266 The second argument in the command callbacks in the server now
2267 includes the SilcServerCommandReplyContext if the command was
2268 called as pending command callback from the command reply.
2269 Otherwise it is NULL. When called as pending the status of the
2270 command reply will be checked and if it was erronous the
2271 error will be sent to the original sender of the command.
2272 This way the client always receives the error messages even
2273 though the server was actually the one who received the error
2274 when it resent the command to router, for example. Affected
2275 files silcd/command[_reply].[ch].
2277 * Fixed sending WHOWAS command's error message to client if
2278 the requested client could not be found. It was missing.
2281 * Changed the CMODE and CUMODE commands reply arguments in the
2282 protocol specification. The Channel ID is now sent in both
2283 of the commands to identify the channel. Implemented this
2284 new feature to the client and server. Affected files
2285 lib/silcclient/command_reply.c and silcd/command.c.
2287 * Made better checks for invite and ban lists in the JOIN
2288 command in server. Affected file silcd/command.c.
2290 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2292 * The server now performs the incoming host IP/DNS lookup
2293 using the silc_socket_host_lookup and thus does not block
2294 the server anymore. Affected file silcd/server.c.
2296 * Completed the multi-thread support for SILC Scheduler in
2297 the lib/silcutil/silcschedule.c.
2299 * Fixed the configure.in.pre to detect the pthread correctly
2302 * Fixed a deadlock in silc_task_queue_wakeup in the file
2303 lib/silcutil/silctask.c.
2305 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Added new function silc_schedule_wakeup that is used in
2308 multi-threaded environment to wakeup the main thread's
2309 schduler. It needs to be used when a thread adds a new task
2310 or removes a task from task queues. After waking up, the
2311 scheduler will detect the task queue changes. If threads
2312 support is not compiled in this function has no effect.
2313 Implemented the wakeup mechanism to both Unix and WIN32
2314 systems. Affected files are lib/silcutil/silcschedule.[ch],
2315 lib/silcutil/unix/silcunixschedule.c and the
2316 lib/silcutil/win32/silcwin32schedule.c.
2318 * Added new function silc_task_queue_wakeup to wakeup the
2319 scheduler by the specified task queue. Affected file
2320 lib/silcutil/silctask.[ch].
2322 * The silc_socket_host_lookup_start now wakes up the scheduler
2323 after adding the timeout task. Affected file is
2324 lib/silcutil/silcsockconn.c.
2326 * The silc_socket_host_lookup is synchronous now if the threads
2327 support is not compiled in. However, the callback is still
2328 called asyncronously through the scheduler, anyway. Affected
2329 file lib/silcutil/silcsockconn.c.
2331 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2333 * Added new function silc_socket_host_lookup to perform
2334 asynchronous IP and FQDN lookups for the socket connection.
2335 Affected files lib/silcutil/silcsockconn.[ch].
2337 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2339 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2340 that may or may not compile the mutex support in.
2342 Changed the silc_mutex_alloc interface. It allocates the
2343 mutex now to the sent pointer and returns TRUE or FALSE.
2345 Affected file lib/silcutil/silcmutex.h.
2347 * Wrote the SILC Task Queue interface to support multi-threads.
2348 Affected file lib/silcutil/silctask.[ch].
2350 * Wrote the SILC Scheduler to support multi-threads. Affected
2351 file lib/silcutil/silcschedule.c.
2353 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2355 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2356 in lib/silcutil/win32/.
2358 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Defined SILC Mutex API and SILC Thread API and implemented
2361 them for Unix. Affected files are
2362 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2363 lib/silcutil/unix/silcunixmutex.c and
2364 lib/silcutil/unix/silcunixthread.c.
2366 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2368 * Fixed the silc_server_remove_clients_by_server's channel
2369 key re-generation. The hash table handling was incorrect
2370 and would not work with many channels. Affected file is
2373 * Fixed some memory leaks around the server code.
2375 * Rewrote the silc_server_get_users_on_channel to support IPv6
2376 based Client ID's. Affected file silcd/server.c.
2378 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2379 specification. However, a separate document must be written
2380 to define the detailed signing procedure and the payload
2381 associated with the flag. Defined the flag to the
2382 lib/silccore/silcchannel.h as well.
2384 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2386 * Changed the dynamic tables to static size tables in the
2387 lib/silccrypt/silchmac.c.
2389 * Removed GCC dependencies from the code. A patch by cras.
2391 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * Do not show the error "Error receiving packet bla bla"
2394 in server if it really was not an error (-2 means that reading
2395 is pending). Affected file silcd/server.c.
2397 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Fixed a possible crash in silc_server_remove_clients_by_server
2400 in silcd/server.c. Fixed there also some memory leaks.
2402 * Fixed the silc_idlist_replace_client_id. It could replace
2403 wrong key in the hash table. Affected file silcd/idlist.c.
2405 * Do not check whether there are global users on the channel
2406 if the channel->global_users is FALSE. Affected functions
2407 silc_server_remove_from_one_channel and
2408 silc_server_remove_from_channels in silcd/server.c. Also,
2409 do not check if the removed client is local as we can be
2410 sure that global client was not removed from the channel
2411 and checking for global users is not needed.
2413 * The silc_server_remove_clients_by_server now re-generates
2414 the channel keys correctly for those channels that had
2415 clients removed from them. Affected file silcd/server.c.
2417 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Found the reason of random crashes in the server. We weren't
2420 ignoring the SIGPIPE signal (which can be sent in write())
2421 and it crashed the server. Affected file silcd/silcd.c.
2423 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * Assure that sock->user_data is not NULL in the function
2426 silc_server_packet_send in silcd/packet_send.c.
2428 * Disconnect the remote connection if it could not be added
2429 to any ID lists in the server. The affected file is
2432 * Check in silc_server_packet_send[_real/dest] that the
2433 socket is not disconnecting and ignore the data if it is.
2434 Affected file silcd/packet_send.c.
2436 * Define inline to __inline on native WIN32 compilation.
2437 Affected file includes/silcwin32.h.
2439 * Added some explicit type casts for inline code since MSVC
2440 require them. Affected files lib/silcutil/silcbuffer.h,
2441 lib/trq/silcdlist.h and lib/trq/silclist.h.
2443 * Print warning in log files from now on if the packet
2444 decryption fails. Affected file silcd/server.c.
2446 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2448 * Changed the `say' client operation's interface to accept
2449 new `type' argument to indicate the type of the message sent
2450 by the library. The application may filter the library's
2451 messages according the type. The affected file is the
2452 lib/silcclient/silcapi.h.
2454 * Added two new functions to lib/silcclient/silcapi.h:
2455 silc_client_del_client and silc_client_del_client_by_id.
2456 Affected file lib/silcclient/idlist.c.
2458 * Moved the clientincludes.h from includes/ to silc/ and
2459 serverincludes.h from includes/ to silcd/.
2461 * The modes for the CMODE and CUMODE are now passed as
2462 uint32 for application with COMMAND_REPLY. The affected
2463 file is lib/silcclient/command_reply.c.
2465 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2467 * /WHOIS without arguments shows client's own information.
2468 Affected file lib/silcclient/command.c.
2470 * Changed PING to not accept any arguments. The specs
2471 says that client can ping only the connected server so
2472 requiring an argument is not needed. Affected file is
2473 lib/silcclient/command.c.
2475 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Fixed a fatal bug in private message sending and reception
2478 encryption and decryption when using private message keys.
2479 The implementation was incorrect and did not follow the
2480 specification. It causd that some of the message were
2481 lost since it did not use the sending and receiving keys
2482 as the protocol suggests. This has been fixed and will cause
2483 incompatibilities with older clients when sending private
2484 message encrypted with private message keys. Affected files
2485 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2486 and various other in Irssi SILC Client.
2488 Added `responder' boolean argument to the functions
2489 silc_client_add_private_message_key[_ske] to indicate when
2490 the key is added as responder or initiator of the key
2493 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Removed the silc_ske_check_version function and created
2496 a SilcSKECheckVersion callback. Added also a function
2497 silc_ske_set_callbacks that is now used to set all SKE
2498 callbacks. The callback functions are not given to
2499 the SKE functions anymore, but this function is used to
2502 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2504 * Added `silc_version' argument to the silc_client_alloc
2505 to define the version of the application for the library.
2506 The library will use the version string to compare it
2507 against the remote host's (usually a server) version
2508 string. Affected file lib/silcclient/silcapi.h
2510 * Added the KE protocol context to Key Agreement context
2511 in client library so that we can abort the SKE if it
2512 is in process when we get timeout. Affected file is
2513 lib/silcclient/client_keyagr.c.
2515 * Do not resolve the client ID forever if it returns in the
2516 first time that such client does not exist. This was done
2517 for example with private message. Affected file is
2518 lib/silcclient/client_prvmsg.c.
2520 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2522 * Do not add regex.h for WIN32. The affected file
2523 includes/silcincludes.h.
2525 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2526 not work yet 100%. It generates the DLL's automatically
2527 when compiling with --with-win32 under cygwin.
2529 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2531 * lib/contrib/regex.c is not compiled on WIN32.
2533 * Added silc_net_get_socket_opt function to the
2534 lib/silcutil/silcnet.h.
2536 * Added includes/silcwin32.h for WIN32 specific includes
2539 * Do not use ptime structure or any of the posix process
2540 functions on WIN32 in lib/silccrypt/silrng.c.
2542 * Added silc_gettimeofday to provide generic function
2543 for struct timeval on all platforms. Added the function
2544 to lib/silcutil/silcutil.h.
2546 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2548 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2549 library as they clearly belong there. As a plus side we
2550 can make the actual socket connection routines platform
2553 Added also new generic function silc_socket_read and
2554 silc_socket_write (that used to be silc_packet_[read/write].
2555 The implementation of these are platform specific.
2557 * Added WIN32 specific routines of silc_socket_[read/write]
2558 to lib/silcutil/win32/silcwin32sockconn.c.
2560 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Added preliminary support for native WIN32 compilation under
2563 cygwin (using the -mno-cygwin option for GCC) to the
2564 ./configure.in.pre. The --with-win32 now prepares the
2565 compilation for native WIN32.
2567 * Rewrote the SILC Scheduler interface in the file
2568 lib/silcutil/silcschedule.h. The scheduler is now context
2569 based and does not have anymore any global static scheduler.
2570 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2571 and created lib/silcutil/win32 directory for WIN32 based
2574 * Added Unix specific network routines to the
2575 lib/silcutil/unix/silcunixnet.c and the old
2576 lib/silcutil/silcnet.c includes now only generic routines.
2578 Added WIN32 specific network routines to the
2579 lib/silcutil/win32/silcwin32net.c.
2581 * Added Unix specific utility functions from the
2582 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2584 * Added WIN32 SILC Scheduler to the file
2585 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2588 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2590 * Do not handle JOIN notify in the server if the target client
2591 is not registered (idata->registered == FALSE). The affected
2592 file is silcd/packet_receive.c.
2594 * Update the nickrec->founder in event_cumode in the Irssi SILC
2595 client. Affected file irssi/src/silc/core/silc-channels.c.
2597 * Fixed the CUMODE_CHANGE notify handling in the server when
2598 server and router are announcing their clients on channels.
2599 Now the mode changes are saved and notified correctly. The
2600 affected file is /silcd/packet_receive.c.
2602 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2603 They really did not replace the cache entry in the ID Cache.
2604 Now they do that. Affected file silcd/idlist.c.
2606 * Fixed the KICK notify handling in the Irssi SILC client to
2607 update the channel records so that the kicked client does not
2608 appear to be on the channel. The affected file is
2609 irssi/src/silc/core/silc-channels.c.
2611 * Always update the conn->current_channel when executing command
2612 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2614 * Fixed the KILL notify handling in Irssi SILC client to remove
2615 the killed client on all channels.
2617 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2619 * Fixed the silc_parse_command_line to remove extra spaces
2620 from the start and end of the arguments. Affected file is
2621 lib/silcutil/silcutil.c.
2623 * Cancel and free any active protocol in the function
2624 silc_server_close_connection. Affected file silcd/server.c.
2626 * Cancel and free any active protocol in the function
2627 silc_client_close_connction. Affected file is
2628 lib/silcclient/client.c.
2630 * Do not execute the KILL command for clients that are in
2631 history (ie. they are not in the network). Affected file is
2634 * Fixed KILL notify handling, client does not crash anymore.
2635 Affected file irssi/src/silc/core/silc-channels.c.
2637 * Reduced the default packet buffer size from 2048 to 1024 in
2638 lib/silccore/silcpacket.c.
2640 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2641 counter to the SKE context that is incresed when the SKE library
2642 performs async operation outside the library. If the outside
2643 process frees the SKE context and FREED status will be set
2644 and the library will detect after the sync operation that the
2645 libary is freed. The affected files are
2646 lib/silcske/silcske[_status].[ch].
2648 * Resolve the client entry information in the function
2649 silc_client_channel_message to assure that NULL pointer is not
2650 passed as client entry to the application. */
2652 * Fixed the task timeout calculation to assure that there is
2653 never negative timeouts. The affected file is
2654 lib/silcutil/silcschedule.c.
2656 * Fixed the channel user mode notification sending in server.
2657 It was sent point-to-point to the router (or to server by router)
2658 but it needs to be destined to a channel. The routines now
2659 supports sending the channel user mode notifys to the channels
2660 when announcing clients and channels. Affected files are
2661 silcd/server.c and silcd/packet_receive.c.
2663 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2664 It did not actually replace the old channel entry in the cache.
2665 Affected file lib/silcclient/client_notify.c.
2667 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Fixed a possible crash in silc_packet_send_prepare. It now
2670 assures always that there is enough space in the buffer and
2671 at the tail area of the buffer (for MAC).
2673 Fixed the inbound buffer reallocation in silc_packet_read.
2674 It was old code and did not handle the reallocation correctly.
2677 The affected file is lib/silccore/silcpacket.c.
2679 * Fixed buffer overflow in silc_parse_nickname in the file
2680 lib/silcutil/silcutil.c.
2682 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2684 * make install generates new server keys only if there is not
2687 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2690 Added check that if the NOREPLY is set then we will not send
2691 the away message. This avoids infinite loop of away messages
2692 if both clients are away. The affected file is
2693 lib/silcclient/client_prvmsg.c.
2695 * Fixed client crash if /NICK was given without arguments.
2696 Affected file lib/silcclient/command.c.
2698 * Server does not send the invite list in INVITE command back
2699 to the client if the list was not altered. Added this notion
2700 to the protocol spec as well. Affected file silcd/command.c.
2702 Fixed possible crash in INVITE command by checking the
2703 value of silc_server_get_client_route command.
2705 * Fixed the INVITE notify type handling. The arguments are now
2706 taken in correct order and client does not crash. The affected
2707 file is irssi/src/silc/core/silc-channels.c.
2709 Removed the "Inviting xxx to channel" message from the
2710 client library away and let the application handle it.
2711 Affected file lib/silcclient/command.c. Added that message
2712 to Irssi SILC client's message formats.
2714 * Fixed CMODE command crash in client. It now checks the
2715 amount of arguments correctly and does not crash. The affected
2716 file is lib/silcclient/command.c.
2718 * Do not create new channel automatically in silc_channels_join
2719 but check whether the channel by that name already exists.
2720 Affected file irssi/silc/core/silc-channels.c.
2722 * Do not send the SERVER_SIGNOFF to router if the disconnected
2723 entity was the router. Affected file silcd/server.c.
2725 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2726 SILC client as it was missing from there.
2728 Added the handling of the KICK notify to the Irssi SILC client
2729 as it was missing. Added "you have been kicked" message to
2730 Irssi SILC client's message modules formats.
2732 Added the handing of the KILL notify to the Irssi SILC client
2733 as it was missing. Added the kill message module formats
2736 The affected file is irssi/src/silc/core/silc-channels.c.
2738 * The router did not save the channel mode the server announced.
2739 Affected file silcd/packet_receive.c.
2741 * Fixed a possible crash in INFO command in server. If the
2742 server did not provide the server info it crashed. Affected
2743 file silcd/command.c.
2745 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * Fixed the GETKEY command in the server to check also the
2748 global list. Otherwise the GETKEY would not work correctly
2749 in normal SILC server. Affected file silcd/command.c.
2751 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * Fixed GETKEY crash, it crashed if the command did not succseed.
2755 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2757 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2758 is now real and not just an macro interface to GMP.
2760 Removed the entire GMP from the source tree and imported new
2761 NSS MPI library instead. Reason for removing GMP is that it is
2762 extremely large and compiles extremely slow. The NSS MPI
2763 is only a few files and compiles in less than 10 seconds.
2764 The speed is also about the same as GMP. The MPI is imported
2765 to lib/silcmath/mpi.
2767 If the system has GMP installed we will still use the GMP.
2768 If it is not then the NSS MPI will be compiled.
2770 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Merged a long nickname (127 characters long) crash bugfix from
2773 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2775 * Merged a freed memory reference bugfix from Irssi CVS tree.
2776 Affected file irssi/src/core/commands.c.
2778 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2780 * Added the server's public key sving and verification to the
2781 server when performing the SKE. This was missing and the
2782 remote server's (or router's) public key was accepted without
2783 checking whether we have it previously or trust it at all.
2784 Affected file silcd/protocol.c.
2786 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2788 * Check in the silc_server_timeout_remote if protocol is active
2789 and make sure that the protocol's final callback is called so
2790 that all memory if freed. Affected file silcd/server.c.
2792 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * silc_server_whois_send_reply crashed the server if the nickname
2795 was 127 characters long. Affected file silcd/command.c.
2797 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Added sanity check to the silc_server_new_client. If the hostname
2800 is provided inside username then check that the provided hostname
2801 really is the same as the resolved one. If the hostname was not
2802 resolved then check it from the public key. Affected file is
2803 silcd/packet_receive.c.
2805 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2806 if the server disconnected us and the connection is not valid
2807 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2809 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2810 the library to the lib/silcutil/silcutil.[ch].
2812 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * Close log file after open. Affected file
2815 lib/silcutil/silclog.c.
2817 * Check whether sock == NULL in silc_client_send_packet and return
2818 if it is. Affected file lib/silcclient/silcclient.c.
2820 * Check rec->entry == NULL in the Irssi SILC Client before
2821 sending the channel message. Affecte file is
2822 irssi/src/silc/core/silc-servers.c.
2824 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2826 * Merged a splitted window bugfix from Irssi CVS tree. The
2827 affected file is irssi/src/fe-text/textbuffer-view.c.
2829 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2830 It did not print nickname.
2832 * Improved the distributions system a bit.
2834 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2836 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2837 irssi/src/fe-text/gui-window.c.
2839 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2840 to in-active server. The affected file is
2841 irssi/src/silc/core/client_ops.c.
2843 * Resolve the client in USERS command reply if the entry does
2844 not have username resolved. The affected file is
2845 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2846 command to WHOIS command to really resolve stuff. The USERS
2847 is not used any more in any critical section so WHOIS can
2848 be used even though it might be slower than IDENTIFY.
2850 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2853 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Changed the protocol API a bit more consistent in the
2856 lib/silccore/silcprotocol.[ch].
2858 * Changed the following headers to ROBODoc format:
2860 lib/silccore/silcpayload.h
2861 lib/silccore/silcprotocol.h
2862 lib/silccore/silcsockconn.h
2864 All core library headers are now formatted.
2866 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Fixed a bug in Irssi SILC client; do not show that you are
2869 server/router operator if you really are not. Affected file is
2870 irssi/src/silc/core/client_ops.c.
2872 * Renamed silc_command_free_payload to silc_command_payload_free.
2873 Affected file lib/silccore/silccommand.h
2875 * Added silcmath.h to include the prototoypes of various routines
2876 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2879 * Changed the following headers to ROBODoc format:
2881 lib/silccore/silcchannel.h
2882 lib/silccore/silccommand.h
2883 lib/silccore/silcid.h
2884 lib/silccore/silcidcache.h
2885 lib/silccore/silcmode.h
2886 lib/silccore/silcnotify.h
2887 lib/silccore/silcpacket.h
2888 lib/silcmath/silcmath.h
2890 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Added checking to the server code not to start the server if
2893 ciphers and stuff are not configured properly. Affected files
2894 silcd/serverconfig.[h] and silcd/server.c.
2896 * Changed the layout of the header files of the public interfaces
2897 in the SILC libraries. The new layout supports ROBODoc
2898 documentation tool (and some others) so that it is easy to create
2899 a library reference manual. All the other headers and source
2900 code must still follow the CodingStyle document. Also source
2901 code must not include these ROBODoc stuffs, only the headers.
2902 Furthermore, all public interface headers must now be named
2903 by using `silc' prefix, example: silcapi.h, silccipher.h.
2904 Some files were renamed due to this. All the other headers
2905 must not be used as public interfaces. I will update the
2906 CodingStyle document later. Changed following headers, so far:
2908 lib/silcclient/silcapi.h
2909 lib/silccore/silcauth.h
2910 lib/silccore/silcprivate.h
2911 lib/silccrypt/silcdh.h
2913 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2917 * Removed silc_client_packet_send_flush from the client library
2918 as it is not needed. Affected file lib/silcclient/client.[ch].
2920 * Added printing of message of unresolved authentication method
2921 to the Irssi SILC client. Added it to the module formats.
2922 Removed the same message from the client library.
2924 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2926 * Added new distribution feature, DISTLABEL. Every distribution
2927 can define own preprocessor label that can be used in the
2928 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2929 file distributions, acconfig.h.pre and prepare.
2931 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * Added Makefile.defines_int to include the actual definitions
2934 for Makefile.defines.in. Tested the new distribution system,
2935 created distributions and tested installation.
2937 * Added AWAY message printing to the Irssi SILC client. Added
2938 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2940 * Added SCONNECT command to call the SILC's CONNECT command.
2941 Cannot use CONNECT directly since Irssi uses that internally.
2942 Affected file irssi/src/silc/core/silc-servers.c.
2944 Added ACTION local command. It is same as ME command but takes
2945 the channel as mandatory argument.
2947 Rewrote some of the Irssi's help files to suite for SILC
2950 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2952 * Added Makefile.defines[.in] that should for now on be included
2953 in all Makefile.am file in the source tree. That file includes
2954 all common compilation definitions for SILC source tree.
2956 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2958 * Minor changes to the ./prepare script to change the package
2959 name according the distribution name to the configure.in.
2961 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Created new distribution system. Added file `distributions'
2964 that defines all the distributions that can be created out of
2965 the SILC source tree. The ./prepare script now reads that
2966 file to determine how to prepare the distributions. The
2967 first argument to the ./prepare is the name of the distribution
2968 and second is the version of the distribution. If given
2969 without arguments it creates the default (toolkit) distribution
2970 with the default version (defined in ./prepare).
2972 All Makefile.am files that are subject to the distributions
2973 are now named as Makefile.am.pre. These are ./Makefile.am
2974 and lib/Makefile.am. Others may be changed later.
2976 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Added invite list, ban list, some key management and connection
2979 error message printing to module formats in the Irssi SILC client.
2981 * Added new silc_client_set_away_message to set the away message
2982 that is back to the person who sent private message. The
2983 affected file lib/silcclient/silcapi.h and the
2984 lib/silcclient/client_prvmsg.c.
2986 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * Fixed the private message sending in the Irssi SILC client,
2989 added local command KEY to the Irssi SILC client.
2991 Added key management and key agreement message formats to the
2992 irssi/src/fe-common/silc/module-formats.[ch].
2994 Added USERS (alias WHO) printing, server/router operator
2995 indication and LIST command printing to the module formats.
2997 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Fixed channel joining notify handling, cumode notify handling
3000 from Irssi SILC client.
3002 * Added SILC specific module-formats to the Irssi SILC client so
3003 that SILC specific message hilighting, colors etc is possible.
3004 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3006 Added channel mode, channel user mode, actions, notices,
3007 whois and whowas printing to the the module-formats.c.
3009 * Fixed a bug in channel deletion in the server. The channel
3010 is not left to the cache even if the channel founder auth mode
3011 is set when there are no users anymore on the channel. Affected
3012 file silcd/server.c.
3014 * The silc_net_localhost now resolves the entire hostname including
3015 the domain name. Affected file lib/silcutil/silcnet.c.
3017 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3019 * Changed the ask_passphrase client operation to be ascynchronous.
3020 It has now a completion callback and a context that the
3021 application must call after it has got the passphrase from
3022 the user. Affected files lib/silcclient/silcapi.h,
3023 lib/silcclient/protocol.c, lib/silcclient/command.c and
3026 Added SilcAskPassphrase callback that the application calls
3027 to deliver the passphrase to the library.
3029 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3030 The public key verification and especially a certificate
3031 verification is asynchronous procedure.
3033 Added new SILC_SKE_STATUS_PENDING status to indicate the
3034 request is pending and a callback will be called to finalize
3037 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3038 indicate that remote end did not send its public key (or
3039 certificate), even though we require it. Added check for this
3040 condition in the SKE. This was a security bug, now fixed.
3042 Defined new SilcSKEVerifyCbCompletion callback that is called
3043 when the verification process is completed.
3045 The affected files lib/silcske/silcske_status.h and
3046 lib/silcske/silcske.[ch].
3048 * Changed the verify_public_key client operation to be async
3049 as well. Defined SilcVerifyPublicKey callback that is used to
3050 indicate the success of the public key verification process.
3052 Changed the server and client to use the new async client
3055 * Changed the Irssi SILC client's internal scheduler to be called
3056 twice as many times as it used to be. As a result the client
3057 should be a bit faster now. Affected file is
3058 irssi/src/silc/core/silc-core.c.
3060 * Added support to Irssi SILC client of asynchronous public key
3061 verification and passphrase inquiry. Affected file is
3062 irssi/src/silc/core/silc-core.c.
3064 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Do not say "You have left channel %s" in client library.
3067 Moved it to the application. Affected files are
3068 lib/silcclient/command.c and silc/client_ops.c.
3070 * Fixed silc_client_get_clients. Command context was not
3071 duplicated and was freed memory in the callback. Affected
3072 file lib/silcclient/idlist.c.
3074 * Do not say "you are now talking..." on JOIN command in the
3075 client library. The appliation must handle it.
3077 * Do not say ".. changed topic to" in command reply in the
3078 client libary. The application must handle it.
3080 * Fixed TOPIC command sending in the client library.
3082 * Fixed a memory leak in silc_client_command_free in the file
3083 lib/silcclient/command.c.
3085 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * Imported a modified version of Irssi client to the source tree.
3088 The Irssi will be used to create a new client called
3089 Irssi SILC. Imported to irssi/.
3091 Added silc_core_init_finish function to the Irssi. Affected
3092 file irssi/configure.in.
3094 A lot changes in the Makefile.ams around the irssi tree.
3096 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Do not rehash if the new size is same as the old size of the
3099 hash table, in the silc_hash_table_rehash*. The affected file
3100 lib/silcutil/silchashtable.c.
3102 * Replaced hash_table_del_by_context calls from the server
3103 (when channel->user_list and client->channels) to the
3104 hash_table_del as it is sufficient and faster.
3106 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Added silc_hash_table_list, silc_hash_table_get and the
3109 SilcHashTableList structure to provide an alternative way to
3110 traverse the hash table. The affected files are
3111 lib/silcutil/silchashtable.[ch].
3113 * Changed the server's idlist routines to use the hash table
3114 routines to optimize the code.
3116 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Replaced the client entry's `channel' list and channel entry's
3119 `user_list' list to hash tables for optimized lookup. Changed
3120 the code to use the hash table interface around the code.
3121 Affected file lib/silcd/idlist.[ch].
3123 * Added `auto_rehash' boolean argument to the function
3124 silc_hash_table_alloc to indicate whether the hash table should
3125 auto-rehash when it thinks is appropriate time. It will
3126 increase the hash table size if the there is twice as much
3127 entries in the table than the size of the table, and will
3128 decrease the size if there are twice as less entries than
3129 the size of the table.
3131 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3133 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3135 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * silc_idcache_purge_by_context deletes the entry now by context
3138 as it is supposed to do. Affected file lib/silccore/idcache.c.
3140 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3141 client is not anymore valid (WHOWAS givens the info) and not
3142 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3144 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Removed the `data' and `data_len' arguments from the ID Cache
3147 interfaces and added `name' argument. ID Cache does not handle
3148 anymore the binary data only a names associated with given ID.
3150 * When hashing a Client ID with silc_hash_id the entire ID is
3151 not hashed anymore, instead only the hash of the Client ID is
3152 hashed. This way we can access the Client ID from the cache
3153 with Client ID but with the hash of the ID (which is a hash of
3154 the nickname) as well without any difference in performance.
3156 Added also silc_idcache_find_by_id_one_ext to do one on one
3157 searching when we have the actual ID. Added also function
3158 silc_hash_client_id_compare. The affected files are
3159 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3161 * When hashing the name associated with a ID it is always done
3162 in lowercase. This way we can access the cache without worrying
3163 about case-sensitivity, even though, for example nicknames are
3166 * Fixed a bug in server with channel message sending. It put
3167 wrong ID type as destination ID. The affected file
3168 silcd/packet_send.c.
3170 * silc_idcache_del_by_context now deletes from all hash tables
3171 by context. Affected file lib/silccore/idcache.c.
3173 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3175 * Changed the client library to use the new ID Cache interface.
3176 Changes around the source tree.
3178 * Added silc_hash_table_rehash_ext to rehash with specific
3179 hash function. Affected file lib/silcutil/silchashtable.[ch].
3181 * Added silc_hash_string_compare to compare two strings in the
3182 hash table. Affected file lib/silcutil/silcutil.[ch].
3184 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Added new function silc_idcache_del_by_context into the
3187 lib/silccore/idcache.[ch].
3189 * Changed the server's ID list routines to use the new ID Cache
3190 interface. Changes around the source tree.
3192 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Added silc_hash_table_del[_by_context]_ext functions in to the
3195 lib/silcutil/silchashtable.[ch].
3197 Removed silc_hash_table_find_all* routines and added new
3198 silc_hash_table_find_foreach to replace them.
3200 Added silc_hash_table_replace_ext function as extended
3201 replacing function. Separated the simple hash table interface
3202 from the extended hash table interface in the file
3203 lib/silcutil/silchashtable.h.
3205 * Fixed minor bugs and changed it to use some of the new
3206 hash table functions in lib/silccore/idcache.c
3208 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Added new function silc_hash_table_find_all to return all keys
3211 in the hash table by the specified key. As the hash table is
3212 collision resistant it also makes it possible to have several
3213 duplicate keys in the hash table. This function may be used to
3214 find all of the keys from the hash.
3216 Added user_context arguments to the SilcHashFunction,
3217 SilcHashCompare and SilcHashDestructor to deliver user specified
3220 Added new fuctions silc_hash_table_find[_all]_ext to do
3221 extended lookup with specified hash and compare functions and
3222 specified user contexts.
3224 Added new function silc_hash_table_add_ext to add the key
3225 with specified hash function and user context.
3227 Added new function silc_hash_table_foreach to traverse all
3228 entrys in the hash table. Added SilcHashForeach callback
3231 Added new function silc_hash_table_del_by_context to delete
3232 the entry only if the context associated with the key matches.
3234 Affected files are lib/silcutil/silchashtable.[ch].
3236 * Removed silc_hash_[server/client/channel]_id and added just
3237 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3238 silc_hash_id_compare to compare two ID's using as the hash table
3239 comparison function. Added also silc_hash_data to hash
3240 binary data and silc_hash_data_compare to compare it.
3242 * Removed silc_idlist_find_client_by_hash as it is not needed
3243 anymore. Affected file silcd/idlist.[ch].
3245 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3246 to use internally the SilcHashTable. The new ID Cache is a lot
3247 faster than the old one. Some of the ID Cache interface was also
3248 rewritten and obsolete and stupid functions were removed.
3250 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * Added entry_count field to the SilcHashTable to keep the number
3253 of the entries in the table. Implemented the function
3254 silc_hash_table_rehash. Added new function
3255 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3257 Fixed a minor bug in silc_hash_table_free.
3259 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3260 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3261 into the lib/silcutil/silcutil.[ch].
3263 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Implemented a collision resistant hash table into the
3266 lib/silcutil/silchashtable[ch]. See the header and the source
3267 for the SilcHashTable API.
3269 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3271 * Merged dotconf version 1.0.2 into lib/dotconf.
3273 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Do not compile anything in lib/silcsim/* if the SIM support
3276 is not enabled. The tree should now compile without problems
3279 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Compiled the SILC under cygwin. Compiled and tested briefly
3282 without problems. More tests needed. The SIMs didn't compile
3285 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3287 * Fixed possible crash in silc_get_username in the
3288 lib/silcutil/silcutil.c.
3290 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Fixed a va_arg in silc/client_ops.c.
3294 * Oops, RC5 routines were named AES and caused some problems
3295 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3297 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Added new SilcIDIP structure into the lib/silccore/id.h and
3300 replaced the old `ip' fields from all SILC ID's to that type.
3301 This is a step towards IPv6 support.
3303 The silc_id_get_len takes now the ID as an extra argument.
3304 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3305 both IPv4 and IPv6 based ID's.
3307 The affected files are lib/silccore/id.[ch] and other files
3308 around the tree using these routines.
3310 * Removed the ID length arguments in server from various
3311 silc_server_send_notify_* routines -> they are not needed
3314 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * Fixed memory leak in silc_encode_pem_file in the file
3317 lib/silcutil/silcutil.c.
3319 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3321 * Check minor version as well in the SKE. Affected files are
3322 silcd/protocol.c and lib/silcclient/protocol.c.
3324 * Added --identifier option to the server so that an identifier
3325 can be when creating the public key for the server. Affected
3326 file is silcd/silcd.c.
3328 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3329 lib/silccrypt/silcpkcs.c.
3331 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Register default ciphers and stuff when using -C option with
3334 the server. Affected file sildc/silcd.c.
3336 * Put back the servers public key filename format, it is better
3337 than the new one. For now, the client keys are saved with the
3338 new filename format. The affected file silc/client_ops.c.
3340 * Implemented the Cipher API for the rest of the ciphers that
3341 did not implement it or implemented it the wrong way.
3343 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Register default ciphers and stuff when using the -S option
3346 in the client. Affected file silc/silc.c. Same also when
3347 creating new key pair with -C option.
3349 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3351 * Fixed the silc_verify_public_key client operation function to
3352 save the public keys differently. The fingerprint is now
3353 used as filename and not the hostname. This way also the
3354 client keys are saved uniquely and not with hostnames. The
3355 affected file is silc/client_ops.c.
3357 * Trimmed the silc_hash_fingerprint function to remove extra
3358 whitespaces from the end of the fingerprint. The affected
3359 file is lib/silccrypt/silchash.c.
3363 * Added silc_cipher_register_default function to register all
3364 default ciphers. It can be used when configuration files
3365 does not exist and the application does not want any specific
3366 ciphers in any specific order.
3368 The SilcDList is now used as silc_cipher_list dynamically
3369 allocated cipher list. Removed the static list all together
3370 and now all ciphers must be allocated to the dynamic list.
3371 The silc_cipher_alloc routine was changed to check only the
3374 All silc_cipher_* routines that used to return int returns
3377 The affected files lib/silccrypt/silccrypt.[ch].
3379 * The same thing was done to silc_hash_* as for silc_cipher_*
3380 routines. Affected files lib/silccrypt/silchash.[ch].
3382 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3383 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3384 Added also silc_pkcs_[un]register[_default] functions.
3385 Removed the data_context from the PKCS API.
3387 * Added silc_hmac_register_default function to register default
3388 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3389 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3390 to unregister all hmacs at once.
3392 * Register the default ciphers, hash functions, PKCSs and HMACs
3393 if client's configuration file does not exist. The affected
3396 * The client did not load the hash functions from the SIM
3397 modules at all. Added support for this. Affected file is
3398 silc/clientconfig.c.
3400 * When decoding public key with silc_pkcs_public_key_decode, check
3401 the supported algorithm only if PKCS are registered. Affected
3402 file lib/silccrypt/silcpkcs.c. The same was done with the
3403 silc_pkcs_private_key_decode.
3405 * Fixed the SILC List routines to keep the list always in order.
3406 It used to change the list's order when traversing the list but
3407 not it preserves the order. Affected file lib/trq/silclist.h.
3409 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * Added the client library to use the SilcSocketConnection's
3412 reference counter (by silc_socket_dup) to prevent the bug that
3413 the socket object may be freed underneath async operation.
3415 * The name resolv library checking fixes in the configure.in.pre.
3418 * Created new version of the protocol drafts for future
3419 development. The -03 drafts are the ones that will be changed
3420 in the trunk now and the -02 will remain as they are.
3422 * Send list of CUMODE notifys to the router when announcing
3423 the channel users to the router. Affected file silcd/server.c.
3424 If the router receiving channel founder CUMODE for a channel
3425 that already has channel founder it will send CUMODE notify
3426 to the sender to remove the channel founder rights from the
3427 announced client. Affected file silcd/packet_receive.c.
3429 * The CUMODE notify may now use Server ID as well as the entity
3430 who changes the mode. Updated protocool specs.
3432 * Updated INSTALL and README files.
3434 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * New web pages in the http://silc.pspt.fi. The pages was
3441 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Implemented the [DenyConnectin] config section in the server.
3444 Added silc_server_config_denied_conn to check whether incoming
3445 connection is denied. Affected file silcd/serverconfig.[ch].
3447 * Do not check the ports when checking the incoming configuration
3448 data if the port is 0, meaning any. Affected file is
3449 silcd/serverconfig.c.
3451 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * Fixed buffer overflow in silc_string_compare in the file
3454 lib/silcutil/silcutil.c.
3456 * Fixed double free in silc_server_command_leave in the file
3459 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3461 * Fixed the version checking in the server. Affected file is
3464 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * Fixed the configuration data fetching when accepting new
3467 connections in the server. Affected file silcd/server.c.
3469 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Added `sender_entry' argument to the function
3472 silc_server_packet_relay_to_channel so that we can check
3473 whether some destination actually belongs to the same route
3474 the sender belongs (ie, we must not resend the packet to the
3475 sender). Affected file silcd/packet_send.[ch].
3477 * Added `servername' field to the SilcClientEntry in the server
3478 to hold the name of the server where client is from. Affected
3479 file is silcd/idlist.h.
3481 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Moved the channel message encrypting in the router betwen
3484 router connections from silc_server_channel_message to the
3485 silc_server_packet_relay_to_channel since we want to check
3486 whether we have anybody channel before encrypting anything.
3487 Affected files silcd/packet_[receive/send].c.
3489 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Fixed the [AdminConnection] server config section to support
3492 multiple entries. Affected file silcd/serverconfig.c.
3494 * Added support into the server to check the validity of the
3495 incoming connection before executing any KE or authentication
3498 * The connection configuration is now saved to the KE and
3499 connection auth protocol contexts and not fetched anymore in
3500 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3502 * The local hosts listenning address and port is also resolved
3503 now when starting the server. We want to have the socket object
3504 to include the real address and port for the listener. Added
3505 new function silc_net_check_local_by_sock into the files
3506 lib/silcutil/silcnet.[ch].
3508 * Fixed a broadcast bug in server -> do not broadcast if we
3511 * Fixed a routing bug. Do not route broadcast packets ever.
3512 Broadcast packets must be processed always and not routed since
3513 they may be destined to some other host than yourself and thus
3514 would get routed without no good reason. Affected file is
3517 * Added function silc_server_config_is_primary_route to check
3518 whether primary router connection has been configured (a router
3519 configuration that we are initiating). If there is not, we
3520 will assume that there is only two routers in the SILC network
3521 and we will use the incoming router connection as our primary
3522 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3524 * Changed the order of the broadcasting. Broadcast _after_ the
3525 packet has been processed not before. Affected file is
3528 * Fixed a [ClientConnection] parsing bug. The port was never
3529 parsed correctly thus resulting to port 0. Affected file
3530 silcd/serverconfig.c.
3532 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3533 argument and did not set the broadcast packet flag. Affected
3534 file silcd/packet_send.c. Fixed same bug in the function
3535 silc_server_send_notify as well.
3537 * If we receive NEW_ID packet for our own ID in the server, ignore
3540 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * Removed the nickname from the Private Message Payload.
3545 Updated the code and the protocol specs.
3547 * Updated protocol specs for submitting to the IETF.
3549 * Tweaked the Random Number Generator a bit. Affected file
3550 lib/silccrypt/silcrng.c. Exported a new function
3551 silc_rng_[global]_add_noise which can be used to add more
3554 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Do not parse packets with different timeout when protocol
3557 is active -> may cause problem with rekey. Affected file
3560 * When server receives signoff notify it must not create
3561 new channel key if the client is on any channels since the
3562 sender of the signoff notify will create it.
3564 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Added printing of error messages during SKE protocol from the
3567 failure packet sent by server during SKE. Affected file
3570 * Removed the client's failure_callback handling with timeout
3571 and handle it immediately when received.
3573 * The SKE library returned wrong type in SUCCESS and FAILURE
3574 packets. They must be 32 bit MSB not 16 bit MSB.
3576 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Ok, rewrote the logic of the re-key and now it seems to work.
3579 I tested it on high traffic with frequent re-keys without
3580 problems. Added hmac_receive (and renamed hmac to hmac_send)
3581 in SilcClientConnection in lib/silcclient/client.h and
3582 in SilcIDListData in silcd/idlist.h. Also, removed the
3583 SilcPacketParserContext's cipher and hmac fields as they are
3584 not needed anymore and actually caused some problems when
3585 the ciphers and hmac's changed underneath the packet parser.
3587 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3589 * If re-key protocol is active then process the incoming packets
3590 synchronously since we must assure that icoming packets encrypted
3591 with the old key is processed before the new keys is set to
3592 use. This is true other packets than for REKEY packets.
3593 Affected file silcd/server.c. The same was done to client library
3594 as well, affected file lib/silcclient/client.c.
3596 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Fixed bug in client and server to accept the force send if
3599 the packet is send from silc_[server/client]_packet_process
3600 function. Otherwise the packets are never delivered, oops.
3602 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3604 * Disable force sending of packets when REKEY protocol is active.
3605 We must assure that no packet is sent directly when rekey is
3606 performed. All packets must be sent through packet queue.
3607 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3608 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3609 function is silc_[server/client]_packet_send_real to check
3612 * Replaced the SIM paths from example config files to
3613 /usr/local/modules. Also, make install creates now
3614 /usr/local/silc/logs directory to hold all the SILC server
3617 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3619 * Made the configure.in.pre work on Solaris. Patch by salo.
3621 * Made all ciphers compatible with non-x86 machines. Defined
3622 CBC mode macros into lib/silccrypt/ciphers_def.h.
3624 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3626 * Fixed the make install.
3628 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * When MAC computation fails the silc_packet_decrypt returned 0
3631 even though it was supposed to return -1. Fixed this. The
3632 affected file is lib/silccore/silcpacket.c.
3634 * Do not replace the config files in /etc/silc (in make install)
3635 if they already exist. Affected file ./Makefile.am.
3637 * Do not send re-key packets immediately but through packet queue.
3638 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3640 * Changed silc_net_check_host_by_sock to return FALSE if the
3641 IP/DNS could not be resolved. Though, it returns the IP address
3642 now even if it could not resolve it (but returns also FALSE).
3643 Affected file lib/silcutil/silcnet.[ch].
3645 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Added silc_pkcs_decode_identifier to decode the public key's
3648 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3649 Added also silc_pkcs_free_identifier. Added also new context
3650 SilcPublicKeyIdentifier.
3652 * Added -S option to the silc client. It is used to dump the
3653 contents of the specified public key file.
3655 * Changed the PKCS api to return the public key length when
3656 setting the public key.
3658 * Fixed a fatal bug in the public and private key file loading.
3659 Affected file lib/silccrypt/silcpkcs.c.
3661 * Execute the packet parsing for client with zero (0) timeout
3662 if the protocol is active. Affected file silcd/server.c.
3664 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Made the key generation options to the silcd program. Added
3667 -C option, equivalent to client's option.
3669 * Added new [ServerKeys] config section to the server. It
3670 configures the server's public and private key.
3672 * Defined generic Public Key Payload into the protocol
3673 specification to send specific type of public keys and
3676 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3677 public key or certificate.
3679 * Implemented the GETKEY command to the server and to the
3680 client library and on user interface.
3682 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Made preliminary `make install' work.
3686 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Added SilcServerRekey context into silcd/idlist.h.
3690 * Added the PFS support as defined in the specification to the
3691 SKE protocol. Affected files lib/silcske/*.c.
3693 * Added `ske_group' field to the SilcServerRekey context to hold
3694 the number of the SKE group that is used with PFS in re-key.
3695 Affected file silcd/idlist.h.
3697 * Added PFS re-key support to the server. Affected file is
3700 * Added silc_protocol_cancel to cancel execution of the next
3701 state of the protocol. Affected file is
3702 lib/silccore/silcprotocol.[ch].
3704 * Added the re-key support with and without PFS to the client
3705 library. Re-key is performed once in an hour, by default.
3707 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3708 Added silc_client_rekey_callback and silc_client_rekey_final.
3709 Affected files are lib/silcclient/protocol.[ch] and
3710 lib/silcclient/client.[ch].
3712 * Removed the `hmac_key' and `hmac_key_len' fields from the
3713 SilcClientConnection structure; not needed. Affected file is
3714 lib/silcclient/client.h.
3718 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Do not ask whether user wants to use the negotiated private key
3721 for private messages, just use it. Affected file is
3722 silc/local_command.c.
3724 * Added `send_enc_key' and `enc_key_len' fields to the
3725 SilcIDListData structure since they are needed in the re-key
3726 phase. Affected file is silcd/idlist.[ch].
3728 * Implemented the simple re-key protocol into the server.
3729 Affected files silcd/server.c and silcd/protocol.[ch]. The
3730 re-key will be performed once in an hour, by default.
3732 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3733 Added silc_server_rekey, silc_server_rekey_callback and
3734 silc_server_rekey_final.
3736 * Removed Tunneled flag from the protocol. Updated the code
3737 and the specifications.
3739 * Adde `pfs' field to the SilcIDListData to indicate whether
3740 the PFS is to be performed in the re-key. Affected file is
3743 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3746 int64 of at least the xintXX size. If void * is less that 4
3747 bytes uint32 * will be used. Defined bool as boolean.
3749 * Changed _ALL_ unsigned long and unsigned int to uint32,
3750 unsgined short to uint16 in the source tree.
3752 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3753 not handle clients that has entry->data.registered == FALSE.
3754 They are not in the network anymore. Affected file is
3757 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3759 * Implemented the sending of the SERVER_SIGNOFF notify in the
3760 server. Affected file is silcd/server.c.
3762 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3763 Added also silc_notify_payload_encode_args into the
3764 lib/silccore/silcnotify.[ch].
3766 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3767 Affected file silcd/packet_receive.c.
3769 * Implemented the SERVER_SIGNOFF notify handling in the client
3770 library. Affected file lib/silcclient/client_notify.c. Also,
3771 implemnted the printing of the SERVER_SIGNOFF info to the
3772 application. Affected file silc/client_ops.c.
3774 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3775 if the deleting was successful. Affected file silcd/idlist.[ch].
3777 * Added support for public key authentication in the connection
3778 authentication protocol in the client library. Affected file
3779 lib/silcclient/protocol.c.
3781 * Changed the server's silc_idlist_get_clients_by_* interface
3782 to support already allocated array so that new entries may be
3783 added to pre-allocated array. Affected file silcd/idlist.[ch].
3784 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3785 and command replies.
3787 * All command reply functions in the server now calls the
3788 pending command callback even if error occured. This way the
3789 error will be delivered to the client as well. Affected files
3790 silcd/command.c and silcd/command_reply.c.
3792 * Fixed INFO command to return local server's info if no server
3793 was provided. Affected file lib/silcclient/command.c.
3795 * Removed RESTART command for good. Updated the code and the
3798 * Rewrote parts of the task system. It is a bit simpler now.
3799 Removed unsued task priorities. The affected files are
3800 lib/silcutil/silctask.[ch].
3802 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Moved the USERS printing from the library to the application.
3805 Affected files lib/silcclient/command.c and silc/client_ops.c.
3807 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Added channel key re-key support. The re-key is perfomed
3812 only by the router and is done once in an hour. Added `rekey'
3813 field to the SilcChannelEntry in the server. Affected files
3814 silcd/server.c and silcd/idlist.h.
3816 * Added silc_task_unregister_by_context into the file
3817 lib/silcutil/silctask.[ch].
3819 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Added SILC_UMODE_GONE mode to indicate when the client is not
3822 present in the SILC network. Added also support to the local
3823 command AWAY that will set this mode. Added support of showing
3824 "xxx is gone" in WHOIS command. The USERS command shows the
3825 gone status as well.
3827 * Fixed setting server and router operator privileges in the
3828 server's UMODE command. Affected file silcd/command.c.
3830 * Merged the SKE KE1 and KE2 payloads into one payload. The
3831 new KE payload is equivalent to the old KE2 payload.
3833 Cleaned up the SKE Start Payload parsing. It now uses the
3834 simple buffer unformatting to do the parsing. A lot faster
3837 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3838 to the SKE that is used to indicate whether both of the SKE
3839 parties should perform authentication. By default only the
3840 responder performs authentication. By setting this flag also
3841 the initiator must do authentication. By default it is unset
3842 since in normal SKE case, client to server connection, only
3843 the responder should do authentication. When doing SKE between
3844 two clients both should perform authentication. Updated the
3845 code and the protocol specs.
3847 * A little fix to IDENTIFY command in the server. Search the
3848 client first by hash not nickname. Affected file is
3851 * Fixed the silc_client_close_connection to support closing
3852 the client to client connections wihtout deleting too much
3853 data. Affected file lib/silcclient/client.c.
3855 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3856 are received if protocol used to be active but is not anymore
3857 the application would crash due to NULL pointer dereference.
3858 Affected files silcd/server.c and lib/silcclient/client.c.
3860 * Added `hash' field to the SilcClientConnection to include
3861 the hash function negotiated in the SKE protocol.
3863 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3864 to set the channel founder authentication data. A client can
3865 claim the founder rights later by providing the authentication
3866 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3867 This way the channel founder can regain the channel founder
3868 privileges even it is left the channel. This works only on
3869 local server and the client must be connected to the same
3870 server to be able to regain the founder rights. Updated the
3871 protocol specs accordingly.
3873 Added support to the CMODE command in the client to set the
3874 founder auth data. Read the README to see how to set it.
3876 Added support to the CUMODE command to claim the founder
3877 rights. Read the README to see how to do it.
3879 Added support for the founder authentication to the Channel
3880 Entry in the server. Affected file silcd/idlist.h.
3882 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3883 server's CMODE command. Affected file silcd/command.c.
3885 * Added the following new functions into lib/silccore/silcauth.[ch]:
3886 silc_auth_get_method and silc_auth_get_data.
3888 * The server now saves the remote hosts public key to the
3889 SilcIDListData pointer. Affected file silcd/protocol.c.
3891 * The normal server now does not remove the channel entry from
3892 the cache if the founder authentication data is set. It used
3893 to remove it if the founder was the last one on the channel on
3894 the server and left the channel. The auth data is saved and
3895 if the channel is re-joined later the old entry is used with
3896 the old auth data. Affected files silcd/command_reply.c and
3899 * Removed the `pkcs' field from the SilcIDListData structure
3900 in the server; it is not used. Affected file silcd/idlist.h.
3902 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3904 * Fixed packet processing on slow links. Partial packets were
3905 never re-processed because the incoming data buffer was cleared
3906 by the application. Application must not directly clear the
3907 sock->inbuf, the packet processing routines handle it. Fixed
3908 this in client library and in server.
3910 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3912 * Fixed the WHOIS and IDENTIFY send reply function to really
3913 check whether to send list or just one entry. Affected file
3916 * Cleaned up the LEAVE command's channel key distribution. The
3917 affected file silcd/command.c.
3919 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3920 can enforce the channel mode as well. In that case the ID
3921 includes the ID of the server. The code now enforces the
3922 mode change if the router have different mode than the server.
3924 * The notify client operation with CMODE_CHANGE notify can now
3925 return NULL client_entry pointer if the CMODE was not changed
3926 by client. Application must check for this.
3928 * Added <Server ID> argument to INFO command to support server
3929 info fetching by Server ID.
3931 * Added silc_server_announce_get_channel_users to get assembled
3932 packets of channel users of the specified channel. Affected
3933 file silcd/server.[ch].
3935 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3936 was freed underneath the ID Cache.
3938 * Re-announce clients when the server received CHANNEL_CHANGE
3939 notify from the router. Affected file silcd/packet_send.c.
3941 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3944 crashed since it did not handle the fact that there is no cipher
3945 called "3" and didn't check the error condition. Now fixed.
3947 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3948 flag. It can be used to send message requests.
3950 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Implemented the RESTART command in the client.
3954 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3955 notice type messages. Added notice printing to the user
3958 * The channel keys are not re-generated if the channel's mode
3959 is PRIVKEY, ie private key on the channel exists. Affected
3960 files silcd/server.c and silcd/command.c.
3962 * Fixed a little bug in channel message delivery when channel
3963 private keys are set in the server. Affected file is
3964 silcd/packet_send.c.
3966 * Changed the setting on channel->on_channel = TRUE from the
3967 silc_client_save_channel_key to the JOIN command reply. The
3968 key payload is not received if the private channel key is set.
3969 Affected file lib/silcclient/command_reply.c and the
3970 lib/silcclient/client_channel.c.
3972 * When the CMODE_CHANGE notify is sent and the channel private
3973 key mode is removed the channel key must be re-generated in
3974 other cells as well. Added this support for the router in the
3975 silcd/packet_receive.c.
3977 * Added new local command NOTICE to send notice message on
3978 channel. Affected file silc/local_command.[ch].
3980 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3982 * Added new local command ME to the client. It is used to send
3983 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3984 some action. Affected file silc/local_command.[ch].
3986 * Changed channel_message and private_message client operations
3987 to deliver the message flags to the application. Added also
3988 the `flags' arguments to the silc_client_send_channel_message
3989 and silc_client_send_private_message functions. Affected file
3992 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Redefined the Private Message Payload to support private message
3995 keys and to support the new private message flags. Updated
3996 the protocol specs. Flags makes it possible to have for example
3997 CTCP style messages.
3999 * Added new type SilcPrivateMessagePayload and defined an API
4000 for it in the lib/silcclient/silcprivate.[ch].
4002 * Tested private message private keys successfully. Tested the
4003 private message key set, unset and list commands with the new
4006 * Redefined the Channel Message Payload to include the channel
4007 message flags (equal with private message flags) to support
4008 for example CTCP style messages.
4010 * Defined some of the message (for channel and private message)
4011 flags. Updated the protocol specs and added the flags to the
4012 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4014 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Added SilcKeyAgreementStatus type to the key agreement routines
4017 to indicate the current status and error if one occured.
4018 The status types are defined in the lib/silcclient/silcapi.h.
4020 * Added new local command KEY that is used to set and unset private
4021 keys for channels, set and unset private keys for private messages
4022 with remote clients and to send key agreement requests and
4023 negotiate the key agreement protocol with remote client. The
4024 key agreement is supported only to negotiate private message keys,
4025 it currently cannot be used to negotiate private keys for channels,
4026 as it is not convenient for that purpose.
4028 * Fixed a minor pending callback setting bug in the function
4029 silc_client_get_client_by_id_resolve, now the function works.
4030 Affected file lib/silcclient/idlist.c.
4032 * Added function silc_net_get_local_port to get local bound
4033 port by socket. Added to lib/silcutil/silcnet.[ch].
4035 * Added `sockets' and `sockets_count' fields to the SilcClient
4036 object. They hold the sockets of the listenning sockets in
4037 the client. Listenning sockets may be for example the key
4038 agreement server. Affected file lib/silcclient/client.[ch].
4039 Added functions the silc_client_add_socket and the
4040 silc_client_del_socket. They are exported to the application
4043 * Added ~./silc/clientkeys to support other client's public keys.
4045 * Renamed verify_server_key client operation to verify_public_key
4046 and added one argument to indicate the type of the connection
4047 (server, client etc.).
4049 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Added silc_server_connection_auth_request to handle the
4052 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4053 silcd/packet_receive.[ch].
4055 * Added silc_server_send_connection_auth_request into the
4056 silcd/packet_send.c to send the connection auth request packet.
4058 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4061 * Fixed the public key authentication in responder side in the
4062 server. The `auth_data' pointer includes the SilcPublicKey
4063 not the path to the public key. Affected file silcd/protocol.c.
4065 * Implemented the public key authentication in the initiator side
4066 in the server. Affected file silcd/protocol.c.
4068 * Removed the [RedirectClient] config section from the server
4069 configuration. Is not needed and I don't want to implement it.
4071 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Cleaned up the CMODE command in the server. It now works
4074 correctly and supports all the modes defined in the protocol.
4075 Affected file is silcd/command.c.
4077 * Added `hmac_name' field to the SilcChannelEntry in the server
4078 to hold the default HMAC of the channel. It can be set when
4079 creating the channel (with JOIN command). Affected files
4082 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4083 type to indicate the change of the current cipher and hmac
4084 on the channel. Client can safely ignore the <cipher> argument
4085 (if it chooses to do so) since the CHANNEL_KEY packet will
4086 force the channel key change anyway. The <hmac> argument is
4087 important since the client is responsible of setting the new
4088 HMAC and the hmac key into use.
4090 * Fixed the CMODE command in the client library as well.
4092 * Tested CMODE command in router environment successfully.
4094 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Show the version of the remote client (or server) when connecting
4097 to the server. It is logged to the log file. Affected file
4098 is silcd/protocol.c.
4100 * Fixed the KILLED notify handling in the client library. The
4101 client must be removed from all channels when receiving the
4104 Also, do not remove the client entry when giving the KILL
4105 command but when the KILLED notify is received.
4107 * Removed silc_idlist_find_client_by_nickname from the server.
4108 Not needed anymore. Affected files silcd/idlist.[ch].
4110 * Implemented the CHANNEL_CHANGE notify type handling to the
4111 server. Affected file silcd/server.c.
4115 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4117 * Added silc_server_send_notify_invite to send the INVITE
4118 notify between routers.
4120 * Implemented the INVITE command correctly to the server.
4122 * Implemented the INVITE notify type handling in the server.
4124 * Implemented the INVITE command to the client library and on the
4127 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * Added function silc_server_get_client_resolve to find the
4130 client entry by ID from all ID lists and then resolve it
4131 (using WHOIS) if it cannot be found. Affected file is
4134 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4136 * Implemented the BAN command to the client library.
4138 * The JOIN command in the server now checks the invite list
4141 * Changed the silc_command_reply_payload_encode_va and the
4142 silc_command_payload_encode_va to support that if argument is
4143 NULL it ignores and checks the next argument. Affected file
4144 lib/silccore/silccommand.c.
4146 * Added silc_server_send_notify_ban to send the BAN notify
4147 type between routers.
4149 * Chaned the silc_notify_payload_encode to support that if
4150 argument is NULL it ignores and checks the next argument.
4151 Affected file lib/silccore/silcnotify.c.
4153 * Tested ban lists in router environment successfully.
4155 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Implemented BAN command to the server, in silcd/command.[ch].
4159 * Removed the BAN and INVITE_LIST modes from the CMODE command
4162 * Added function silc_string_match to regex match two strings.
4163 Affected files lib/silcutil/silcutil.[ch].
4165 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Redefined parts of the SilcChannelEntry in the server to support
4168 the new ban and invite lists.
4170 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Redefined the INVITE command. The same command can be used to
4173 invite individuals to the channel but also to manage the invite
4174 list of the channel (to add to and remove from the invite list).
4175 Updated the protocol specs.
4177 * Added new command SILC_COMMAND_BAN that can be used to manage
4178 the ban list of the channel. Updated the protocol specs.
4180 * Removed the channel modes: the SILC_CMODE_BAN and the
4181 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4182 in the CMODE command. The equivalent features are now available
4183 using INVITE and BAN commands. Updated the protocol specs.
4185 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4186 in the network about change in the current ban list. The notify
4187 type is not used by the client.
4189 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4190 support the invite lists.
4192 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Added new function silc_string_regexify that converts string
4195 including wildcard characters into regex string that can
4196 be used by the GNU regex library. Added into the file
4197 lib/silcutil/silcutil.[ch].
4199 Added silc_string_regex_combine to combine to regex strings
4200 into one so that they can be used as one regex string by
4201 the GNU regex library. Added into the file
4202 lib/silcutil/silcutil.[ch].
4204 Added silc_string_regex_match to match two strings. It returns
4205 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4207 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Imported GNU regex to the soruce tree into lib/contrib.
4210 Fixed some compiler warning from the regex.c.
4212 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Fixed MOTD command in the server to work in router environment.
4216 * Fixed the MOTD command in the client library to support
4217 the server argument in the command.
4219 * Added `nickname_len' argument to the silc_idlist_add_client
4220 in the server, as the `nickname' argument may be binary data
4223 * Added silc_idlist_get_channels to return all channels from
4226 * Implemented LIST command to the server. Affected file is
4229 * Implemented the LIST command to the client library and on the
4232 * Added [<user count>] argument to the LIST command reply.
4233 With private channels the user count is not shown.
4235 * Updated TODO and README.
4237 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * The client entry's data.registered must be TRUE even with
4240 global client entry on global client list. The data.registered
4241 is used to check whether the client is anymore in the network,
4242 for example with WHOWAS command so it must be valid.
4244 * Fixed the WHOWAS command in the server. It now actually works
4245 in router environment. Added function into silcd/command_reply.c
4246 silc_server_command_reply_whowas_save.
4248 * Added silc_idlist_purge function to the silcd/idlist.c
4249 to periodically purge the ID Cache.
4251 * Fixed INFO command in the server. It works now in router
4252 environment. Added <server name> argument to the INFO command
4253 reply. Updated the protocol specs.
4255 * Fixed minor bug in silc_idcache_purge to not purge if the
4256 expire value is zero.
4258 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4259 they were buggy because of the WHOWAS information.
4261 * Fixed local command MSG to handle the async resolving of
4262 the remote client properly. It used to fail the first MSG.
4263 Affected file silc/local_command.c.
4265 * Added `data_len' field to SilcIDCache context.
4267 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * Update TODO. Todo in commands in the server.
4271 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4273 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4274 used by routers as broadcast packet to inform other routers
4275 about the changed user mode.
4277 Implemented the notify handling in the server. Affected file is
4278 silcd/packet_receive.c. Added the function
4279 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4281 * Added new generic Channel Payload and deprecated the New Channel
4282 Payload. The New Channel Payload is now the generic Channel
4285 * Added new argument `mode' to the silc_server_send_new_channel
4286 as it is required in the Channel Payload now.
4288 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4289 and created a new and real SilChannelPayload to represent the
4290 new generic Channel Payload. Implemented the encode/decode
4291 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4293 * Added silc_server_get_client_channel_list to return the list
4294 of channels the client has joined for WHOIS command reply.
4295 Affected file silcd/server.[ch].
4297 * Implemented the channel list sending in the WHOIS command reply
4298 in server and in the client.
4300 Implemented the channel list displaying on the user interface
4301 as well. Affected file silc/client_ops.c.
4303 * Added silc_channel_payload_parse_list to parse list of Channel
4304 Payloads. It returns SilcDList list of SilcChannelPayloads.
4305 Client for example can use this function to parse the list of
4306 channels it receives in the WHOIS command reply. The caller
4307 must free the list by calling silc_channel_payload_list_free.
4308 Affected files lib/silccore/silcchannel.[ch].
4310 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Added one new argument <user mode> to the WHOIS command reply
4313 to return the mode of the user in SILC. Updated the protocol
4316 Implemented it to the server and client.
4318 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4320 * Fixed the mode printing on the user interface on joining.
4321 Affected file silc/client_ops.c.
4323 * Implemented the UMODE command and user modes in general to the
4324 client library and to the user interface.
4326 * Implemented the UMODE command to the server.
4328 * The server now sends UNKNOWN_COMMAND error status if client sends
4329 unknown command. Affected file silcd/command.c.
4331 * All server commands now handle the command identifier the right
4332 way when sending the command reply to the client. The client can
4333 use to identify the command replies with the identifier.
4335 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Added silc_server_get_client_route to resolve the route to
4338 the client indicated by the client ID. Affected file is
4341 * Added silc_server_relay_packet as general function to relay
4342 packet to arbitrary destination. This deprecates functions
4343 like _send_private_message_key, _relay_notify etc. Affected
4344 file is silcd/packet_send.[ch].
4346 Removed silc_server_send_key_agreement,
4347 silc_server_send_private_message_key and
4348 silc_server_packet_relay_notify functions from the file
4349 silcd/packet_send.[ch].
4353 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4354 server. Affected file silcd/packet_receive.[ch].
4356 * Implemented the KILL command to the client. Implemented the
4357 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4358 Affected files lib/silcclient/command[_reply].c and
4359 lib/silcclient/client_notify.c. Implemented the KILL notify
4360 printing in the user inteface.
4362 * Fixed a lot silc_parse_nick memory leaks from the client
4363 library in the file lib/silcclient/command.c.
4365 * Changed the silc_server_send_notify_on_channels's `sender'
4366 argument from SilcSocketConnection to SilcClientEntry to
4367 check the sender as entry and not as connection object and not
4368 to send to the client provided as argument. The affected file
4369 is silcd/packet_send.[ch].
4371 * The notify packets that are destined directly to the client used
4372 to not to be processed by the server. Now changed that and the
4373 server processes all notify packets. After relaying the packet
4374 to the client the notify packet is processed in the server.
4376 * The silc_server_free_client_data now checks whether there is
4377 pending outgoing traffic for the client and purges the data to
4378 the network before removing the client entry.
4380 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4382 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4383 an client is killed from the SILC Network. Updated the protocol
4386 Added new function silc_server_send_notify_killed to the
4387 silcd/packet_send.[ch].
4389 * Added function silc_server_packet_relay_notify to relay notify
4390 packets that are destined directly to a client. In this case
4391 the server does not process the notify packets but merely relays
4392 it to the client. Affected file silcd/packet_send.[ch].
4394 Added also silc_server_packet_process_relay_notify to check
4395 whereto relay the notify. Affected file is
4396 silcd/packet_receive.[ch].
4398 * Implemented the KILL command to the server.
4402 * Added the backup schema desgined last fall to the protocol
4403 specs for everyone to see. The specification is in the
4404 *-spec-xx.txt draft and the packet type definitions for the
4405 backup routers is in *-pp-xx.txt draft. Thusly, added also
4406 new packet type SILC_PACKET_CELL_ROUTERS.
4408 * A big security problem in the implementation discovered. The
4409 signoff of an client did not cause new channel key generation
4410 which it of course should've done. The channel keys must be
4411 always re-generated when client leaves (or signoffs) the channel.
4412 The silc_server_remove_from_channels funtion now handles
4413 the channel key re-generation.
4415 * Added `sender' argument to the silc_server_send_notify_on_channels
4416 to not to send the client provided as argument. Affected file
4417 silcd/packet_send.[ch].
4419 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Implemented OPER and SILCOPER commands into the server and
4424 * Added silc_auth_verify and silc_auth_verify_data to verify
4425 the authentication directly from the authentication payload.
4426 It supports verifying both passphrase and public key based
4427 authentication. Affected file lib/silccore/silcauth.[ch].
4429 * Added `hash' field to the SilcIDListData structure. It is the
4430 hash negotiated in the SKE protocol. Affected file is
4433 * Slight redesigning of the SilcAuthPayload handling routines.
4434 Do not send SilcPKCS but SilcPublicKey as argument.
4436 * Implemented the public key authentication support to the
4437 serverconfig. The public key is loaded from the provided path
4438 and saved as authentication data to void * pointer. Thus,
4439 changed the unsigned char *auth_data to void *auth_data;
4441 * Fixed SHUTDOWN command to send the reply before the server
4442 is shutdown. :) Affected file silcd/command.c.
4444 * Fixed fatal bug in CONNECT command. The hostname was invalid
4445 memory and server crashed. Affected file silcd/command.c.
4447 * Fixed fatal bug in CLOSE command. The server_entry became
4448 invalid but was referenced later in the command. Affected file
4451 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Fixed fatal bug in failure packet handling. Server ignored
4454 the failure and thus crashed when it came.
4458 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4461 that the command may be executed only once in (about) 2 seconds.
4462 The old SILC_CF_LAG flag is same but allows command bursts up
4463 to five before limiting.
4465 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4466 server code. Various commands now includes the CF_LAG_STRICT
4467 flag to disallow any kind of miss-use of the command.
4469 * Fixed the silc_buffer_unformat to not to allocate any data
4470 if the length of the data is zero. It used to allocate the
4471 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4473 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Changed the format of AdminConnection configuration section
4476 in the server. Added username of the admin to the format.
4477 Affected files silcd/serverconfig.[ch].
4479 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4480 to return admin configuration data by host, username and/or
4483 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Implemented WHOWAS command to the server. Added the functions:
4487 silc_server_command_whowas_parse,
4488 silc_server_command_whowas_send_reply,
4489 silc_server_command_whowas_from_client and
4490 silc_server_command_whowas_from_server
4492 * Added <Client ID> argument to the WHOWAS command reply. Updated
4493 the protocol specs accordingly.
4495 * Implemented WHOWAS command and command_reply to the client
4498 Implemented the WHOWAS printing on the user interface.
4500 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Added new argument to the WHOWAS command reply, the real name.
4503 It is an optional argument. Updated the protocol specs.
4505 * Added SilcIDCacheDestructor callback that is registered when
4506 the SilcIDCache is allocated. The callback is called when
4507 an cache entry in the ID Cache expires, or is purged from the
4508 cache. Added into lib/silccore/idcache.[ch].
4510 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4511 to destruct the client entries when the cache entry expires.
4512 Other ID Cache's in server and in the client library ignores
4515 * If the ID Cache entry's `expire' field is zero then the entry
4516 never expires. Added boolean `expire' argument to the
4517 silc_idcache_add function in the lib/silccore/idcache.[ch].
4518 If it is TRUE the default expiry value is used.
4520 * Added silc_server_free_client_data_timeout that is registered
4521 when client disconnects. By default for 5 minutes we preserve
4522 the client entry for history - for WHOWAS command.
4524 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Added support to the server to enforce that commands are not
4527 executed more than once in 2 seconds. If server receives
4528 commands from client more frequently, timeout is registered
4529 to process the commands. Affected file silcd/command.c.
4530 Added new function silc_server_command_process_timeout.
4532 * Changed NICK_NOTIFY handling in client library to check that
4533 if the client's nickname was changed, so there is no need to
4534 resolve anything from the server.
4536 * Removed error printing from the WHOIS and IDENTIFY commands.
4537 If error occurs then it is ignored silently in the client library.
4538 The application, however, may map the received error to
4539 human readable error string. The application currently maps
4540 the NO_SUCH_NICKNAME error to string.
4542 * Made the command status message public to the application. Moved
4543 them from lib/silcclient/command_reply.c to
4544 lib/silcclient/command_reply.h. The application can map the
4545 received command status to the string with the
4546 silc_client_command_status_message function.
4548 * Added check to the server to check that client's ID is same
4549 as the Source ID in the packet the client sent. They must
4552 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Added dist-bzip hook to the Makefile.am to make bzip2
4555 compressed distributions.
4557 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Server now enforces the maximum length for the nickname and
4560 the channel as protocol specification dictates. 128 bytes for
4561 nickname and 256 bytes for channel name.
4563 * Moved the WHOIS printing to the application. The client libary
4564 does not print out the WHOIS information anymore, the application
4565 must do it. Renamed silc_client_command_reply_whois_print to
4566 the silc_client_command_reply_whois_save.
4568 The client's idle time is also sent to the application now, and
4569 the idle is shown on screen.
4571 * Added silc_client_command_reply_identify_save to save the
4572 received IDENTIFY entries.
4574 * Do not check for channel private keys in message sending and
4575 reception if the channel does not have the PRIVKEY mode set.
4576 Affected file lib/silclient/client_channel.c.
4578 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4581 just surfaced after chaning the JOIN procedure.
4583 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Added silc_client_get_clients_by_list to get client entries
4586 from Client ID list, that is returned for example by JOIN
4587 and USERS command replies. The application should use this
4588 function for example when JOIN command reply is received to
4589 resolve the clients already on the channel (library does not
4590 do that anymore as USERS command reply is not used in the JOIN
4591 procedure anymore). Affected files lib/silcclient/silcapi.h and
4592 lib/silcclient/idlist.c.
4594 * JOIN command reply and USERS command reply returns now SilcBuffer
4595 pointers instead of unsigned char pointers when returning
4596 the client list and mode list.
4598 * Added <Client ID> argument to the JOIN command reply, mainly
4599 for the server to identify for which client the command was
4600 originally sent. Updated protocol specs accordingly.
4602 * Added SilcDlist private_key pointer to the SilcChannelEntry
4603 in the client to support the channel private keys. Affected
4604 file is lib/silcclient/idlist.h.
4606 * Added SilcChannelPrivateKey argument to the function
4607 silc_client_send_channel_message so that application can choose
4608 to use specific private ke if it wants to. If it is not provided,
4609 the normal channel key is used, unless private keys are set.
4610 In this case the first (key that was added first) is used
4611 as the encryption key.
4613 * Implemented the support for channel private key handling.
4614 Implemented the following functions:
4616 silc_client_add_channel_private_key,
4617 silc_client_del_channel_private_keys,
4618 silc_client_del_channel_private_key,
4619 silc_client_list_channel_private_keys and
4620 silc_client_free_channel_private_keys
4622 Affected file lib/silcclient/client_channel.c.
4624 * Added the support for the private keys in the channel message
4625 sending and encryption and in the message reception and
4626 decryption. Affected funtions are
4627 silc_client_send_channel_message and silc_client_channel_message.
4629 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added SKE's key verify callback to the client library's
4632 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4634 * Removed the statement that server (or router) must send USERS
4635 command reply when joining to the channel so that the client
4636 knows who are on the channel. Instead, the client list and
4637 client's mode list is now sent in the JOIN command reply to the
4638 client who joined channel. This is better solution.
4640 * Added function silc_server_get_users_on_channel and function
4641 silc_server_save_users_on_channel to the silcd/server.[ch].
4643 * Removed function silc_server_command_send_users from the
4646 * Do not show topic on the client library anymore. The topic is
4647 sent in the command reply notify to the application and the
4648 application must show the topic now.
4650 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Added client searching by nickname hash into the IDENTIFY and
4653 WHOIS commands in the server as they were clearly missing from
4654 them. Affected file is silcd/command.c.
4656 * Fixed a bug in private message receiving in the client library.
4657 The remote ID was freed and it wasn't supposed, now it is
4660 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Minor fix to the channel payload; allocate the data area, as it
4663 needs to be of specific length.
4665 * If the key agreement port is zero then the operating
4666 system will define the bound port. Affected files are
4667 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4669 * Added new function silc_channel_payload_decrypt into the file
4670 lib/silccore/silcchannel.[ch].
4672 * Moved the channel message etc, check from silc_packet_decrypt
4673 to applications. The library calls now a generic
4674 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4675 when the packet is either normal or special. This was done to
4676 allow more wide range of checking that was not allowed when
4677 the code was in library. Now applications can do virtually any
4678 checks to the packet and return to the library the decision how
4679 the packet should be processed. Affected files are
4680 lib/silccore/silcpacket.[ch].
4682 Added silc_server_packet_decrypt_check to the server and
4683 silc_client_packet_decrypt_check to the client library.
4685 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4686 to send with specified source and destination information.
4688 * Channel message delivery between routers was broken after the
4689 channel key distribution was fixed earlier. The channel key
4690 was used be to distributed to other routers as well which is not
4691 allowed by the protocol. Now this is fixed and channel keys
4692 really are cell specific and the channel message delivery between
4693 routers comply with the protocol specification.
4695 * Fixed various commands in server to check also the global list
4696 for the channel entry and not just the local list. The affected
4697 file silcd/command.c.
4699 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Added assert()s to buffer formatting and unformatting routines
4702 to assert (if --enable-debug) when error occurs. Affected
4703 file: lib/silcutil/silcbuffmt.c.
4705 * Changed to auto-reconnect to check whether the remote host is
4706 router and register the re-connect timeout if it is. It used
4707 to check that whether we are normal server, but router must do
4708 auto-reconnect with another router as well. Affected file
4711 * Removed the [<key len>] option from CMODE command as the cipher
4712 name decides the key length, nowadays. See the defined ciphers
4713 from the protocol specification.
4715 * Added [<hmac>] option to the CMODE command to define the HMAC
4716 for the channel. Added SILC_CMODE_HMAC channel mode.
4718 * Added [<hmac>] option for the JOIN command so that user can
4719 select which HMAC is used to compute the MACs of the channel
4722 * Added Hmac field to the Channel Message Payload. The integrity
4723 of plaintext channel messages are now protected by computing
4724 MAC of the message and attaching the MAC to the payload. The
4725 MAC is encrypted. Now, it is clear that this causes some
4726 overhead to the size of the packet but rationale for this is that
4727 now the receiver can verify whether the channel message decrypted
4728 correctly and also when private keys are set for the channel the
4729 receiver can decrypt the packet with several keys and check from
4730 the MAC which key decrypted the message correctly.
4732 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4733 lib/silccrypt/silccipher.[ch].
4735 * Added silc_hash_len to return the digest length into the
4736 lib/silcrypt/silchash.[ch].
4738 * Rewrote parts of Silc Channel Payload interface in the
4739 lib/silccore/silcchannel.[ch]. The encode function now also
4740 encrypts the packet and parse function decrypts it.
4742 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Fixed a minor formatting bug in the SKE's key material processing.
4745 It actually might have processed the keys wrong way resulting
4748 * Redefined the mandatory HMAC algorithms and added new algorithms.
4749 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4750 and hmac-md5 truncated to 96 bits. The mandatory is now
4751 hmac-sha1-96. Rest are optional (including the one that used
4752 to be mandatory). Rationale for this is that the truncated HMAC
4753 length is sufficient from security point of view and can actually
4754 make the attack against the HMAC harder. Also, the truncated
4755 HMAC causes less overhead to the packets. See the RFC2104 for
4758 * Added new [hmac] configuration section. The SKE used to use
4759 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4760 is of course wrong. The official names that must be proposed in
4761 the SKE are the ones defined in the protocol specification
4762 (hmac-sha1-96 for example). The user can configure any hmac
4763 using any hash function configured in the [hash] section. At
4764 least, the mandatory must be configured.
4766 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4768 * Added HMAC list to the SKE proposal list. It has now both
4769 hash algorithm list and HMAC list. This makes the protocol
4770 incompatible with previous versions. The SKE now seems to work
4771 the way it is supposed to work, for the first time actually.
4773 * Defined plain Hash algorithms to the protocol specification.
4776 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Implemented support for key agreement packets into the server.
4779 Added functions silc_server_key_agreement and
4780 silc_server_send_key_agreement. Other than these functions,
4781 server has nothing to do with this packet.
4783 * Added support for private message key packets into the server.
4784 Added functions silc_server_private_message_key and
4785 silc_server_send_private_message_key.
4789 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4790 called in the protocol's final callback instead in the END
4791 protocol state. This makes a little more sense and in the same
4792 time in client we can use the same protocol routines for normal
4793 key exchange and to key agreement packet handling as well.
4795 * Added to both client's and server's KE protocol context the
4796 SilcSKEKeyMaterial pointer to save the key material. We will
4797 bring the key material to the protocol's final callback by doing
4798 this. The final callback must free the key material.
4800 * Added SKE's packet_send callback into client's KE protocol
4801 context so that the caller can choose what packet sending function
4802 is used. This way we can use different packet sending when
4803 doing normal SKE when doing key agreement packet handling (in
4804 the key agreement packet handling we do not want to encrypt
4807 * Implemented the responder side of the key agreement routines
4808 in the client. The client can now bind to specified port and
4809 accept incoming key negotiation. The key material is passed
4810 to the application after the protocol is over.
4812 * Implemented the processing of incoming Key Agreement packet
4813 in the client. Added function silc_client_key_agreement to
4816 * Implemented the intiator side of the key agreement routines
4817 in the client. The client can now initiate key agreement with
4818 another remote client. The key material is passed to the
4819 application after the protocol is over.
4821 * Created client_keyagr.c to include all the key agreement
4824 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4825 SILC_TASK_CALLBACK except that it is not static.
4827 * Created client_notify.c and moved the Notify packet handling
4828 from the client.[ch] into that file.
4830 * Created client_prvmsg.c and moved all private message and
4831 private message key routines from the client.[ch] into that file.
4833 * Create client_channel.c and moved all channel message and
4834 channel private key routines from the client.[ch] into that file.
4836 * Changed silc_client_get_client_by_id_resolve to resolve with
4837 WHOIS command instead of IDENTIFY command, in the file
4838 lib/silclient/idlist.c.
4840 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Implemented the SKE's responder side to the Client library.
4844 * When FAILURE is received to the protocol do not trust it
4845 blindly. Register a timeout to wait whether the remote closes
4846 the connection as it should do it, only after that process the
4847 actual failure. This was changed to both client and server.
4849 * Added client_internal.h to include some of the structures
4850 there instead of client.h in lib/silcclient/.
4852 * Added function silc_task_unregister_by_callback to unregister
4853 timeouts by the callback function.
4855 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Some "Incomplete WHOIS info" errors has been appearing on the
4858 log files. Took away the entry->userinfo check from WHOIS
4859 reply sending. The entry->userinfo is now " " if client did not
4860 provide one. I thought this was fixed earlier but something
4861 is wrong still. Let's see if the error still appears.
4863 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Fixed a minor bug in the login when the channel key is
4866 re-generated in the server. It used to generate the key in
4867 wrong order and thus caused problems in the channel traffic.
4869 * Fixed a minor bug in channel key distsribution after
4870 KICK command. The key was not sent to the router even though
4873 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Added silc_ske_process_key_material_data as generic routine
4876 to process any key material as the SILC protocol dictates. The
4877 function is used by the actual SKE library but can be used by
4878 applications as well. This relates to the private message keys
4879 and the channel private keys since they must be processed the
4880 same way the normal SILC session keys. The protocol dictates
4881 this. Affected files: lib/silcske/silcske.[ch].
4883 Added also silc_ske_free_key_material to free the
4884 SilcSKEKeyMaterial structure.
4886 * Defined silc_cipher_set_key function to set the key for
4887 cipher without using the object's method function. The affected
4888 files: lib/silccrypt/silccipher.[ch].
4890 * Implemented silc silc_client_add_private_message_key,
4891 silc_client_add_private_message_key_ske,
4892 silc_client_del_private_message_key,
4893 silc_client_list_private_message_keys and
4894 silc_client_free_private_message_keys functions in the
4897 Added functions silc_client_send_private_message_key to send
4898 the Private Message Key payload and silc_client_private_message_key
4899 to handle incoming Private Message Key payload.
4901 * Added Cipher field to the Private Message Key payload to set
4902 the cipher to be used. If ignored, the default cipher defined
4903 in the SILC protocol (aes-256-cbc) is used.
4905 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Removed lib/silcclient/ops.h file.
4909 Redefined parts of the SILC Client Library API. Created new
4910 file silcapi.h that deprecates the ops.h file and defines the
4911 published Client Library API. Defined also private message key
4912 API and channel private key API into the file.
4914 This is the file that the application must include from the
4915 SILC Client Library. Other files need not be included by
4916 the application anymore.
4918 * Added new key_agreement client operation callback and also
4919 defined the Key Agreement library API for the application.
4921 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4924 is used by clients to request key negotiation between another
4925 client in the SILC network. If the negotiation is started it
4926 is performed using the SKE protocol. The result of the
4927 negotiation, the secret key material, can be used for example
4928 as private message key.
4930 Implemented the Key Agreement payload into the files
4931 lib/silccore/silauth.[ch].
4933 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Redefined ciphers for the SILC protocol. Added some new ciphers
4936 and defined the key lengths for the algorithms. Changed the
4937 code accordingly. The default key length is now 256 bits.
4939 * Fixed SKE key distribution function silc_ske_process_key_material
4940 when the key length is more than 128 bits. The default key
4941 length in SILC is now 256 bits.
4943 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4944 to indicate unsupported algorithm.
4946 * Renamed rijndael.c to aes.c and all functions as well.
4948 * Fixed a long standing channel key setting bug in client library.
4949 Weird that it has never surfaced before.
4951 * Fixed bug in channel deletion. If the entire channel is removed
4952 then it must also delete the references of the channel entry
4953 from the client's channel list as the client's channel entry and
4954 the channel's client entry share same memory.
4956 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Implemented CONNECT and SHUTDOWN commands in the client.
4960 * Implemented CLOSE command to the client.
4962 * Added the function silc_idlist_find_server_by_name into the
4963 files silcd/idlist.[ch].
4965 Added the function silc_idlist_find_server_by_conn into the
4966 files silcd/idlist.[ch].
4968 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * DIE command was renamed to SHUTDOWN. Updated the both code
4973 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4974 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4976 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4979 * Added function silc_server_create_connection function to create
4980 connection to remote router. My server implementation actually
4981 does not allow router to connect to normal server (it expects
4982 that normal server always initiates the connection to the router)
4983 so the CONNECT command is only good for connecting to another
4986 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4989 or some other client was kicked from the channel.
4991 Implemented the handling of the notify type to both client
4994 Implemented silc_server_send_notify_kicked to send the KICKED
4995 notify. It is used to send it to the server's primary router.
4997 * Implemented the KICK command into server and client.
4999 * Added `query' argument to the silc_idlist_get_client function
5000 to indicate whether to query the client from server or not if
5003 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5004 to indicate that the client is not channel founder.
5008 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5010 * Removed the rng context from SilcPacketContext structure and
5011 changed that the packet routine uses the Global RNG API.
5013 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Added support for quit message that client can "leave" on the
5016 channel when it quits the SILC. It is ditributed inside the
5017 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5019 Added silc_server_free_client_data that will take the
5020 signoff message as argument.
5022 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5024 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Updated parts of the protocol specification to keep it up
5029 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5032 payloads in one packet.
5034 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5035 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5036 use now the new List flag.
5038 * Also deprecated the following packet types: REPLACE_ID,
5039 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5041 * Added list support for Notify packet in server.
5043 * Added silc_server_send_notify_channel_change to send the
5044 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5045 the silc_server_send_replace_id.
5047 * Added silc_server_send_notify_nick_change to send the
5048 NICK_CHANGE notify type. Deprecates the function
5049 silc_server_send_replace_id.
5051 * Added silc_server_send_notify_join to send the JOIN notify type.
5052 Deprecates the function silc_server_send_new_channel_user.
5054 * Added silc_server_send_notify_leave to send LEAVE notify type.
5055 Deprecates the function silc_server_send_remove_channel_user.
5057 * Added silc_server_send_notify_cmode and
5058 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5059 types. Deprecates the silc_server_send_set_mode function.
5061 * Added SERVER_SIGNOFF notify type to indicate that server has
5062 quit. This means that all clients on the channel from that
5063 server will drop. This can be also used when netsplit happens.
5065 Deprecated REMOVE_ID packet type since it is not needed anymore
5068 Added silc_server_send_notify_server_signoff to send the
5069 SERVER_SIGNOFF notify type. Deprecates the function
5070 silc_server_send_remove_id.
5072 Added also silc_server_send_notify_signoff to send the
5073 SIGNOFF notify type.
5075 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5076 SILC protocol from this day on. Changed the protocol
5077 specification as well.
5079 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5080 notify type. It is used between routers to notify about
5081 topic changes on a channel.
5083 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5086 * Partly updated the protocol specification to comply with the
5087 changes now made. It is still though a bit outdated.
5089 * The JOIN notify type now takes one extra argument <Channel ID>.
5090 The packet used to be destined to the channel but now the
5091 JOIN type may be sent as list thus it is impossible to
5092 destine it to any specific channel. By adding this argument
5093 it is again possible.
5095 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Added CREDITS file. The CHANGES and CREDITS file will appear
5098 in the distribution as well.
5100 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5103 types in the server's silcd/packet_receive.c.
5105 * Implemented CMODE and CUMODE to work in router environment.
5107 * Fixed minor encoding and decoding buglet from the
5108 lib/silccore/silcmode.c.
5110 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5113 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5115 * Changed all SilcConfigServer* and silc_config_server* to
5116 SilcServerConfig* and silc_server_config*, respectively.
5119 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Associated the ID (client or server ID) to the Authentication
5122 Payload to avoid any possibility of forging. Updated the
5123 protocol specification and the code accordingly.
5125 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * The RSA key length is now save to the RsaKey context in the
5128 key generation process in lib/silccrypt/rsa.c. The key length
5129 is now used to figure out the maximum size of the block allowed
5130 to be encrypted/signed.
5132 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5133 is equivalent to the silc_mp_mp2bin but does not allocate any
5136 * Changed silc_mp_mp2bin API to take length argument. If it is
5137 non-zero then the buffer is allocated that large. If zero, then
5138 the size is approximated using silc_mp_sizeinbase, which however
5141 * Created Global RNG API which is global RNG that application can
5142 initialize. After initializing, any routine anywhere in the
5143 code (including library) can use RNG without allocating a new
5144 RNG object. This was done to allow this sort of use of the
5145 RNG in code that has no chance to allocate RNG object. All
5146 applications currently allocate this and many routines in the
5147 library use this. Affected file lib/silccrypt/silcrng.[ch].
5149 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5150 it to use the Global RNG API.
5152 * Defined Authentication Payload into protocol specification that
5153 is used during SILC session to authenticate entities. It is
5154 used for example by client to authenticate itself to the server
5155 to obtain server operator privileges.
5157 Implemented this payload into the lib/silccore/silcauth.[ch].
5158 Implemented also routines for public key based authentication
5159 as the new protocol specification dictates.
5161 Moved definitions of different authentication methods from
5162 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5164 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5165 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5166 silc_pkcs_verify_with_hash functions into the file
5167 lib/silccrypt/silcpkcs.[ch].
5169 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * The client entry's userinfo pointer must be always valid.
5172 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5173 will fail since it requires the userinfo. Now, the userinfo
5174 is allocated as "" if actual userinfo does not exist. Actually,
5175 it must exist and it is totally Ok to drop client connections
5176 that does not announce the userinfo. However, we will make
5177 this workaround for now.
5179 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5180 to return the remote port by socket.
5182 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5185 SILC_SERVER_PENDING_EXEC and added an new macro
5186 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5187 data or when error occurs while processing the pending command.
5189 Added new argument `destructor' into silc_server_command_pending
5190 and to the SilcServerCommandPending object. This destructor is
5191 now called after calling the pending callback or if error occurs
5192 immediately. If error occurs the actual pending callback won't
5193 be called at all - only the destructor. The destructor may be
5194 NULL if destructor is not needed.
5196 All this applies for client library code as well. Similar
5197 changes were made there as well for the pending commands.
5199 In the client, the application must now allocate the
5200 SilcClientCommandContext with the silc_client_command_alloc
5203 * Added reference counter to the SilcServerCommandContext. Added
5204 function silc_server_command_alloc and silc_server_command_dup
5207 Same type of functions added to the client library for the same
5210 * Removed the cmd_ident from IDListData away since it is now
5211 global for all connections. It is the command identifier used
5212 in command sending and with pending commands. The affected file
5215 * Added reference counter to the SilcSocketConnection objecet to
5216 indicate the usage count of the object. The object won't be
5217 freed untill the reference counter hits zero. Currently only
5218 server uses this, and client ignores it. The client must be
5219 set to use this too later. The affected files are
5220 lib/silccore/silcsockconn.[ch]. Added also the function
5221 silc_socket_dup to increase the reference counter.
5223 This was mainly added because it is possible that the socket
5224 is removed underneath of pending command or other async
5225 operation. Now it won't be free'd and proper DISCONNECTING
5226 flags, etc. can be set to avoid sending data to connection that
5227 is not valid anymore.
5229 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5230 the connection. After that it sets SILC_SET_DISCONNECTED.
5231 It is, however, possible that the socket data is not still freed.
5232 The silc_server_packet_process now checks that data is not
5233 read or written to connection that is DISCONNECTED. The socket
5234 get's freed when the reference counter hits zero.
5236 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Changed the client operation API: channel_message operation's
5239 `sender' is now the client entry of the sender, not the nickname
5240 and the `channel' is the channel entry, not the channel name.
5242 In the private_message operation the `sender' is now also the
5243 client entry of the sender not the nickname.
5245 Affected file is lib/silcclient/ops.h and all applications
5246 using the client operations.
5248 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Moved the calling of ops->connect() from connect_to_server_final
5251 into receive_new_id functin since that is the point when the
5252 client is actually allowed to send traffic to network. The
5253 affected file is lib/silcclient/client.c.
5255 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5258 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5259 (if needs broadcasting) instead of broadcasting the packets one
5260 by one which would make a burst in the network traffic.
5262 * Added `broadcast' argument to the functions in silcd/server.[ch]
5263 silc_server_create_new_channel[_with_id] to indicate whether
5264 to send New Channel packet to primary router.
5266 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Added new function into the silcd/server.[ch] files:
5269 silc_server_create_new_channel_with_id to create new channel with
5270 already existing Channel ID.
5272 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5273 lib/silccore/silcpacket.h. This packet is used t send list of
5274 Set Mode payloads inside one packet. Server uses this to set
5275 the modes for the channels and clients on those channels, that it
5276 announced to the router when it connected to it. The protocol
5277 specification has been updated accordingly.
5279 * The silc_server_new_channel did not handle the packet coming
5280 from normal server as it normally does not send that. However,
5281 when it announces its channels it does send it. Implemented
5282 the support for that.
5284 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5285 into the file lib/silccore/id.h.
5287 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5289 * Fixed memory leaks in the functions silc_idlist_del_client,
5290 silc_idlist_del_channel and silc_idlist_del_server in the file
5291 silcd/idlist.c. All of those leaked like a sieve.
5293 * Fixed some small memory leaks in the client's function
5294 silc_client_notify_by_server.
5296 * Added functions into silcd/server.c: silc_server_announce_clients,
5297 silc_server_announce_channels and silc_server_announce_server.
5298 These functions are used by normal and router server to announce
5299 to its primary router about clients, channels and servers (when
5300 router) that we own. This is done after we've connected to the
5303 These functions effectively implements the following packet types:
5304 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5305 and SILC_PACKET_NEW_ID_LIST.
5307 * Added new functions into the silcd/packet_receive.[ch]:
5308 silc_server_new_id_list, silc_server_new_channel_list and
5309 silc_server_new_channel_user_list to handle the incoming
5310 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5312 * Added support of changing Channel ID in the function
5313 silc_server_replace_id. If the server that announces a channel
5314 to the router already exists in the router (with same name but
5315 with different Channel ID), router is responsible to send
5316 Replace ID packet to the server and force the server to change
5317 the Channel ID to the one router has.
5319 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5320 client that the Channel ID has been changed by the router. The
5321 normal server sends this to the client. Client must start using
5322 the new Channel ID as the channel's ID.
5324 Implemented handling of this new type into lib/silcclient/client.c
5325 into the function silc_client_notify_by_server.
5327 * Added new function silc_idlist_replace_channel_id into the files
5328 silcd/idlist.[ch] to replace the Channel ID.
5330 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * Call silc_server_command_identify_check always when processing
5333 the IDENTIFY command in silcd/command.c
5335 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5338 send keepalive packets. The packet can be sent by clients,
5339 servers and routers.
5341 Added function silc_socket_set_heartbeat into the file
5342 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5343 If not set, the heartbeat is not performed. The actual
5344 heartbeat is implemented in the low level socket connection
5345 library. However, application is responsible of actually
5348 Added silc_server_send_heartbeat to send the actual heartbeat
5349 packet into silcd/packet_send.[ch]. Server now performs
5350 keepalive with all connections.
5352 * Added silc_task_get_first function into lib/silcutil/silctask.c
5353 to return the timeout task with shortest timeout. There was a bug
5354 in task unregistration that caused problems. TODO has been
5355 updated to include that task system must be rewritten.
5357 * The client library will now resolve the client information when
5358 receiving JOIN notify from server for client that we know but
5359 have incomplete information.
5361 * Rewrote parts of silc_server_remove_from_channels and
5362 silc_server_remove_from_one_channel as they did not remove the
5363 channel in some circumstances even though they should've.
5365 * Encryption problem encountered in server:
5367 The LEAVE command used to send the Channel Key packet to the
5368 router immediately after generating it. However, the code
5369 had earlier sent Remove Channel user packet but not immediately,
5370 ie. it was put to queue. The order of packets in the router
5371 was that Channel Key packet was first and Remove Channel User
5372 packet was second, even though they were encrypted in the
5373 reverse order. For this reason, MAC check failed. Now, this
5374 is fixed by not sending the Channel Key packet immediately but
5375 putting it to queue. However, this is more fundamental problem:
5376 packets that are in queue should actually not be encrypted
5377 because packets that are sent immediately gets encrypted
5378 actually with wrong IV (and thus MAC check fails). So, packets
5379 that are in queue should be encrypted when they are sent to
5380 the wire and not when they put to the queue.
5382 However, the problem is that the current system has not been
5383 designed to work that way. Instead, the packet is encrypted
5384 as soon as possible and left to the queue. The queue is then
5385 just purged into wire. There won't be any fixes for this
5386 any time soon. So, the current semantic for packet sending
5389 o If you send packet to remote host and do not force the send
5390 (the packet will be in queue) then all subsequent packets to the
5391 same remote host must also be put to the queue. Only after the
5392 queue has been purged is it safe again to force the packet
5395 o If you send all packets immediately then it safe to send
5396 any of subsequent packets through the queue, however, after
5397 the first packet is put to queue then any subsequent packets
5398 must also be put to the queue.
5400 Follow these rules and everything works fine.
5402 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5404 * Added new function silc_server_remove_clients_by_server to
5405 remove all client entries from ID list when the server connection
5406 is lost. In this case it is also important to invalidate all
5407 client entires as they hold the invalid server entry. This
5408 fixes fatal bug when server has lost connection and will reconnect
5411 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Made some sanity checks to silc_server_daemonise like to check
5414 whether the requested user and group actually exists.
5416 * Added sanity check to SKE's silc_ske_responder_finish to check
5417 that the public and private key actually is valid.
5419 * Invalidate the client's nickname when receiving Replace ID
5420 packet and the Client ID is being replaced. This means that the
5421 server will query the nickname if someone needs it (client)
5424 * Sort the ID Cache in client library when the ID Cache data
5425 has changed (needs sorting).
5427 * Do not allow for SILC client to create several connections to
5428 several servers. The client does not support windows right now
5429 and generating multiple connections causes weird behaviour.
5431 Irssi-silc client does support windows and can handle several
5432 connections without problems, see: www.irssi.org and SILC plugin.
5434 * Fixed some places where client was added to the IDList. The
5435 rule of thumb is following (in order to get everything right):
5436 If the client is directly connected local client then the
5437 `connection' argument must be set and `router' argument must be
5438 NULL to silc_idlist_add_client function. If the client is not
5439 directly connected client then the `router' argument must
5440 bet set and the `connection' argument must be NULL to the
5441 silc_idlist_add_client function.
5443 * The funtion silc_server_packet_send_local_channel actually did
5444 not check whether the client was locally connected or not. It
5445 does that now. Fixed a bug related to LEAVE command.
5447 * Fixed Remove Channel User payload parsing bug in server's
5448 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5450 * The server's silc_server_save_channel_key now checks also the
5451 global ID list for the channel as it might not be in the local
5452 list. Fixed a bug related to LEAVE command.
5454 * Is this the end of the [<unknown>] buglet that has been lurking
5455 around for a long time? A little for loop fix in server's
5456 silc_server_command_whois_parse that is used by both IDENTIFY
5457 and WHOIS command. At least, this was a clear bug and a cause
5458 of one type of [<unknown>] buglet.
5460 * WHOIS and IDENTIFY commands call the function
5461 silc_server_command_[whois/identify]_check function even if
5462 we are not router server.
5464 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Added --with-gmp configuration option. If set the GMP
5467 is always compiled in the SILC source tree. If not set then
5468 it is checked whether the system has the GMP3 installed. If
5469 it has then the GMP won't be compiled (the system's headers
5470 and library is used), if it doesn't have it then the GMP is
5471 compiled in the SILC source tree.
5473 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Changed RSA private exponent generation to what PKCS #1
5476 suggests. We try to find the smallest possible d by doing
5477 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5478 not security fix but optimization.
5480 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Added new config entry [Identity] to fork the server and run
5483 it as specific user and group. A patch from Bostik.
5485 * Imported Dotconf configuration library into lib/dotconf.
5486 This will be used to create the SILC configuration files later.
5487 It will appear in the distsribution after this commit.
5489 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5491 * A big code auditing weekend happening. Auditing code for
5492 obvious mistakes, bugs and errors. Also, removing any code
5495 Removed files for being obsolete:
5497 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5498 inline in the file lib/silcutil/silcbuffer.h)
5500 o lib/silcutil/silcbufutil.c (the header has inline versions)
5502 Changed code to fix possible error conditions:
5504 o The buffer formatting routines now check that the destination
5505 buffer really has enough space to add the data. This applies for
5506 both buffer formatting and unformatting
5507 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5508 unformatting was changed to accomodate following rules:
5509 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5510 sent to the function while XXX_*STRING will not allocate or copy
5511 the data into the buffer. Instead it sets the pointer from the
5512 buffer into the pointer sent as argument (XXX_*STRING used to
5513 require that the pointer must be allocated already). This change
5514 makes this whole thing a bit more consistent and more optimized
5515 (note that the data returned in the unformatting with XXX_*STRING
5516 must not be freed now). The routines return now -1 on error.
5518 o Tried to find all code that use buffer_format and buffer_unformat
5519 and added return value checking to prevent formatting and
5520 especially unformatting errors and possible subsequent fatal
5523 o Changed ske->x and ske->KEY to mallocated pointers in
5524 lib/silcske/silcske.h. Fixed possible data and memory leak.
5526 o Added return value checking to all *_parse* functions. Fixed
5527 many memory leaks as well.
5529 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5530 so that buffer overflows would not happen. All code now also
5531 checks the return value as it can fail.
5533 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Added reconnection support to server if the normal server looses
5536 its connection to the router (for example if router is rebooted).
5537 The server performs normal reconnection strategy implemented
5538 to the server. Affected file silcd/server.c.
5540 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5542 * Added new packet type SILC_PACKET_SET_MODE that is used to
5543 distribute the information about changed modes (for clients,
5544 channels and clients channel modes) to all routers in the
5545 network. Updated the protocol specification accordingly.
5547 Added functions into silcd/packet_send.c and
5548 silcd/packet_receive.c: silc_server_send_set_mode,
5549 silc_server_set_mode.
5551 Added new files silcmode.[ch] into lib/silccore that implements
5552 the encoding and decoding of Set Mode Payload. Added new type
5553 SilcSetModePayload. Moved the definitions of different modes
5554 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5556 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * Oops, a little mistake in server's connection authentication
5559 protocol. The protocol is not ended with FAILURE but with
5560 SUCCESS if the authentication is Ok. :) Affected file is
5563 * Implemented NICK_CHANGE notify handling in server in the file
5564 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5565 the local clients on the channel. After the changing nickname
5566 in router environment snhould work and the [<unknown>] nickname
5567 should appear no more.
5569 The silc_server_replace_id function that receives the Replace ID
5570 payload now sends the NICK_CHANGE notify type also in the file
5571 silcd/packet_receive.c
5573 * Changed WHOIS and IDENTIFY command to support the maximum amount
5574 of arguments defined in protocol specs (3328 arguments). This
5575 fixed a bug that caused problems when there were more than three
5578 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Added extra parameter, command identifier, to the
5581 silc_client_send_command so that explicit command identifier
5584 Changed that ID list routines uses specific command identifier
5585 when sending WHOIS/IDENTIFY requests to the server so that they
5586 can be identified when the reply comes back.
5588 Affected files lib/silcclient/command.[ch],
5589 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5591 * Added `sender' argument to silc_server_packet_send_to_channel
5592 to indicaet the sender who originally sent the packet to us
5593 that we are now re-sending. Ignored if NULL. Affected file
5594 silcd/packet_send.[ch].
5596 * Added some server statistics support in silcd/server_internal.h
5597 SilcServerStatistics structure and around the server code. Also
5598 send some nice statistics information when client is connecting
5601 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Fixed channel ID decoding in server's JOIN command reply in
5604 silcd/command_reply.c
5606 * Fixed braodcasting of replace ID payload to not to send it if
5607 we are standalone server in silcd/packet_receive.c.
5609 * Fixed all channel message sending routines to not to send
5610 packets to clients that has router set, since they are routed
5611 separately in the same function earlier. Affects file
5612 silcd/packet_send.c and all channel packet sending functions.
5614 * In USERS reply, res_argv[i] are not allocated, the table
5615 is allocated. Thus changed that free the table, not its
5618 * In server's whois_check and identify_check if the client is
5619 locally connected do not send any WHOIS commands - they are not
5622 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Fixed some minor bugs in client when sending WHOIS command. The
5625 arguments was in wrong order.
5627 * Removed statis function add_to_channel from server in
5628 silcd/command.c that was previously used with the joining but
5631 * Tested USERS command in router environment successfully with two
5632 routers, two servers and two clients.
5634 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Reorganized the USERS command and command reply in client library
5637 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5638 When the command is given by user we register a pending command
5639 callback that will reprocess the command after the reply has been
5640 received from the server. When reprocessing the packet we then
5641 display the information. Thus, the USERS information is displayed
5642 now in the command callback instead of in the command reply
5643 callback. The processing of the command is same as previously
5644 when server has sent the command reply in the JOINing process.
5646 * Added to USERS command in silcd/command_reply.c to join the client,
5647 we didn't use to know about, to the channel after we've created
5648 a client entry for it. Also, for clienet we did know already still
5649 check whether it is on the channel or not and add it if not.
5651 * Removed silc_server_command_join_notify as the function and its
5654 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5656 * Changed the client's pending command handling to the same as the
5657 server's pending command handling. It is also now possible to
5658 execute command reply functions from other command reply
5659 function as the function callbacks for commands and command
5660 replies are one and same. The pending commands are not static
5661 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5662 in client connection context. Thus, pending commands are server
5663 connection specific as it is convenient.
5665 Changed the function silc_client_command_pending and
5666 silc_client_command_pending_del and added new function
5667 silc_client_command_pending_check. Removed the
5668 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5671 * Added cmd_ident, current command identifier, to the client
5672 connection context in lib/silcclient/client.h to keep track on
5673 command identifiers used in command sending. Client's command reply
5674 function handling now supports the mandatory command identifiers.
5676 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5677 funtions in client to fully support pending command callbacks.
5679 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5680 as one of the arguments to the application in the command reply
5683 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5684 before first releasing SILC but came back. Now it is removed again
5685 and should come back nomore. The FORWARDED flag was used only
5686 by the JOINing procedure by forwarding the command packet to router.
5687 Now, the JOINing procedure has been changed to more generic (due
5688 to various router environment issues) and FORWARDED is not needed
5689 anymore for anything. The protocol specification is yet to be
5692 Now, removed silc_server_packet_forward from server and the flag
5693 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5695 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5697 * Renamed NAMES command to USERS command. The NAMES was named that
5698 due to historical reasons. Now it is renamed. Also, rewrote
5699 parts of the USERS command. The nickname list is not sent anymore
5700 by the server. Only Client ID and mode lists are sent in the USERS
5701 command. Changed this also to the protocol specification.
5703 The client now resolves the names and stuff after it receives
5704 the USERS list from the server when joining to the channel.
5706 * WHOIS and IDENTIFY commands has been changed to support multiple
5707 Client ID's per command. One can now search for multiple users
5708 in the network by sending only one WHOIS or IDENTIFY command.
5709 Changed the code and the protocol specifications.
5711 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5712 uses silc_server_command_whois_parse to parse the request. */
5714 * If normal server, do not parse the WHOIS and IDENTIFY requests
5715 before sending it to the router. Saves some time.
5717 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * Fixed JOIN command on client library. Wrong number of arguments
5720 used to crash the client.
5722 * Added silc_server_channel_has_global function to check whether
5723 channel has global users or not.
5725 * Added silc_server_channel_has_local function to check whether channel
5726 has locally connected clients on the channel.
5728 * The silc_server_remove_from_one_channel now checks whether the
5729 channel has global users or not after given client was removed from
5730 the channel. It also checks whether the channel has local clients
5731 on the channel anymore. If it does not have then the channel entry
5732 is removed as it is not needed anymore.
5734 * The silc_server_notify now checks on JOIN notify whether the joining
5735 client is one of locally connected or global. If it is global then
5736 the channel has now global users on the channel and that is marked
5737 to the channel entry. Also, it now saves the global client to
5738 global list who is joining and JOINs it to the channel. This is
5739 for normal server, that is.
5741 Changed silc_server_send_notify_on_channel,
5742 silc_server_packet_relay_to_channel and
5743 silc_server_packet_send_to_channel check if we are normal server
5744 and client has router set (ie. global client) do not send the
5745 message to that client, as it is already routed to our router.
5747 * Implemented LEAVE notify type handling in silc_server_notify
5750 * Tested LEAVE command in router environment successfully. Tested
5751 with two routers, two servers and two clients.
5755 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5757 * Implemented SIGNOFF notify type handling in silc_server_notify
5760 * silc_server_remove_id now removes the client entry from all channels
5761 it has joined and thusly sends SIGNOFF notify type.
5763 * Rewrote the NAMES list generation in server by removing two excess
5764 loops. The lists are created now inside one loop.
5766 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5768 * silc_server_remove_channel_user checks now also global list
5769 for channel and client.
5771 * silc_server_new_channel_user checks now both local and global
5772 list for channel and client. Fixed a bug in client id decoding.
5773 Used to decode wrong buffer.
5775 * silc_server_channel_message checks now both local and global
5776 list for channel entry.
5778 * Tested channel joining (hence JOIN) in router environment
5779 successfully. Tested with two routers, two servers and two
5782 * Tested channel message sending in router environment successfully.
5784 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Added silc_server_save_channel_key into server.[ch] to save the
5787 received channel key in Channel Key payload processing. It is
5788 also used in JOIN command reply handling.
5790 Equivalent function silc_client_save_channel_key added into
5791 client.[ch] into client library.
5793 * Changed JOIN command reply to send information whether the channel
5794 was created or not (is existing already) and the channel key
5795 payload. Changed protocol specs accordingly.
5797 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5798 the request was sent by ID and not by nickname. Crashed on
5801 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5804 now correctly save the received data.
5806 * silc_server_free_sock_user_data now notifies routers in the
5807 network about entities leaving the network.
5809 At the same time implemented functions silc_server_remove_id
5810 and silc_server_send_remove_id to receive and send REMOVE_ID
5811 packets. The packet is used to notify routers in the network
5812 about leaving entities. The ID removed will become invalid in
5815 * Added function silc_idlist_del_server into server. Removes and
5816 free's server entry from ID list.
5818 * silc_server_private_message function now checks, if we are router,
5819 that the destination ID really is valid ID, naturally.
5821 * In router when NEW_ID packet is received (for new client) the
5822 hash of the Client ID is saved in the ID Cache but the
5823 client->nickname is set to NULL, instead of putting the hash
5826 IDENTIFY command now also checks that client->nickname must be
5827 valid. If it is not if will request the data from the server who
5828 owns the client. Added new function
5829 silc_server_command_identify_check.
5831 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5832 to set the command to already allocated Command Payload.
5834 * Tested private message sending in router environment with two
5835 routers, two servers and two clients. Fixed minor bugs and now
5838 * Fixed segfault from client's NAMES command. Used to crash if
5841 * Forwarded packets must not be routed even if it is not destined
5842 to the receiver. Changed server code comply with this.
5844 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * Added `require_reverse_mapping' boolean value to ServerParams
5847 structure. If TRUE (not default) the server will require that
5848 the connecting host has fully qualified domain name.
5850 If the reverse mapping is not required and hostname could not be
5851 found the IP address is used as hostname.
5853 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Implemented version string checking to both client and server.
5856 The check is incomplete currently due to the abnormal version
5857 strings used in development version of SILC.
5859 * Changed all command functions in server to use the new
5862 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5864 * Changed char *data to unsigned char *data in ID Cache system to
5865 support binary data as ID Cache data. Changed code to support
5866 binary data in lib/silccore/idcache.c.
5868 * Renamed silc_server_packet_relay_command_reply to
5869 silc_server_command_reply as it is normal packet receiving
5870 function. Rewrote the function to accept command replys for
5871 servers and not only for clients.
5873 * Mark remote router always as registered server if we are connecting
5874 to it. Otherwise, commands sent by the router to us are ignored.
5876 * All ID List find routines now returns the ID Cache Entry pointer
5877 as well if requested.
5879 * WHOIS command works now in router environment, tested with two
5880 routers, two servers and two clients.
5882 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5883 in router environment (as it is almost equivalent to WHOIS) but
5884 hasn't been tested thoroughly. Added new functions:
5886 silc_server_command_identify_parse
5887 silc_server_command_identify_send_reply
5888 silc_server_command_identify_from_client
5889 silc_server_command_identify_from_server
5891 * Disabled route cache adding because adding two different ID's with
5892 same IP replaces the old cache entry thus giving wrong route.
5893 The entry->router->connection is always the fastest route anyway
5894 so route cache may not be needed. Of course, new routes maybe
5895 established after receiving the ID when the entry->router->connection
5896 might not be anymore the most optimal.
5898 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Add route cache for received ID for fast routing.
5902 * Added silc_server_packet_route to route received packet on router
5903 that is not destined to us.
5905 * Renamed silc_server_get_route to silc_server_route_get.
5907 * Added id_string and id_string_len fields into SilcServer to
5908 include encoded ServerID for fast comparing without excess
5909 encoding of the ID's.
5911 * Cleaned up WHOIS command on server side. Added following static
5914 silc_server_command_whois_parse
5915 silc_server_command_whois_check
5916 silc_server_command_whois_send_reply
5917 silc_server_command_whois_from_client
5918 silc_server_command_whois_from_server
5920 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5921 arguments in command replies. All command functions should be
5922 updated to use this macro.
5924 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Minor typo fixes on command reply handling on server.
5928 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Added silc_server_command_add_to_channel internal routine to add
5931 the client to the channel after router has created the channel and
5932 sent command reply to the server.
5934 * Added generic silc_server_send_command to send any command from
5937 * Use static buffer with ID rendering instead of duplicating data.
5939 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5941 * Fixed a channel user mode bug when joining to a channel server gave
5942 everybody channel founder rights, oops.
5944 * We mark ourselves as the router of the incoming server connection
5945 if we are router ourselves. This way we can check in some packet
5946 sending functions whether it is locally connected server. For
5947 incoming router connections we put NULL.
5949 * For router sending packets locally means now always sending the
5950 packet cell wide; to local clients and local servers. For normal
5951 server sending packet locally means sending it to only local
5954 * Fixed the JOIN command to really work in router environment. If the
5955 channel is created it is always created by the router. Router is
5956 also responsible of making the initial joining to the channel,
5957 sending JOIN notify to the sending server and distributing
5958 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5959 does not exist server doesn't do anything else but forward the
5960 command to the router which performs everything.
5962 * Added silc_server_send_channel_key function to send the Channel Key
5965 * Added silc_server_create_channel_key to create new channel key. The
5966 channel key is now re-generated everytime someone joins or leaves
5967 a channel, as protocol dictates. Note: channel->key_len is the
5970 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5973 packet_receive.[ch] to separate packet sending and receiving
5974 routines. The server.[ch] now includes everything else including
5975 actual packet processing (writing and reading data) and other
5978 Renamed silc_server_private_message_send_internal to
5979 silc_server_send_private_message. The routine is still though
5980 used only to relay private messages as server does not send
5981 private messages itself.
5983 Renamed silc_server_new_channel to silc_server_create_new_channel
5984 and added new function sicl_server_new_channel that handles the
5985 incoming New Channel packet. Added also new sending function
5986 silc_server_send_new_channel to send New Channel Payload.
5988 * Added new function silc_server_notify to process incoming notify
5989 packet to the server/router. Server may then relay the notify
5990 to clients if needed.
5992 * Added new function silc_server_new_channel_user to process incoming
5993 New Channel User packet. Router will redistribute the packet and
5994 send JOIN notify to its local clients and locally connected servers
5995 if needed. Normal server will send JOIN notify to its local client
5996 on same channel when received this packet. Added also corresponding
5997 sending function silc_server_send_new_channel_user to sent the
6000 * Added boolean route argument to send_notif_to_channel and
6001 packet_send_to_channel functions to attempt to route the packet
6002 if it is TRUE and send only locally if it is FALSE.
6004 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * silc_server_replace_id now broadcasts the received replace ID
6007 packet if it is not broadcast packet already. The router must
6008 broadcast to inform other routers about changed ID.
6010 * Added backpointer to server's router into SilcServer context in
6011 silcd/server_internal.h.
6013 * Fixed silc_server_packet_broadcast to send correct broadcast
6016 * The channel key is now distributed to the local client as soon
6017 as it is received from the router (in router environment) so that
6018 no other packet may be sent for the channel until client has
6021 * silc_server_remove_channel_user now broadcasts the received
6022 Remove Channel User packet if it is not broadcast packet already.
6023 The router must broadcast to inform other routers about removed
6026 * Added users field into SilcPacketContext that is a reference count
6027 of the context. One can increase the reference count by calling
6028 silc_packet_context_dup which is now changed to just increase the
6029 reference count instead of duplicating the data. The reference
6030 count is decresed by calling silc_packet_context_free that will
6031 free the data after the reference count hits zero.
6033 For now on the packet context and everything allocated into it
6034 (including the raw packet from network) must be freed by calling
6035 the new silc_packet_context_free function. Added also new function
6036 silc_packet_context_alloc that must be used now to allocate the
6037 context. This also means that if a routine is asynchronous from
6038 silc_[client/server]_packet_parse_type the packet context must
6039 be duplicated by calling silc_packet_context_dup. Otherwise it
6040 gets free'd after silc_[client/server]_packet_parse_type returns.
6041 Also, one must remember that if packet is duplicated then its
6042 reference count must be decresed by calling the free function as
6043 many times as it was duplicated.
6045 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6046 from both client and server.
6048 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * Made joining to a channel working in router environment.
6052 * Cleaned up JOIN command on server side and create function
6053 silc_server_command_join_channel internal routine to make the
6056 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Changed silc_command_pending list to SilcDList. Also, added
6059 `ident' field to SilcServerCommandPending structure to identify
6060 the reply and to call correct callback.
6062 Added silc_server_command_pending_check function to replace the
6063 corresnponding macro. The silc_command_pending list is not
6066 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6067 to set identifier to previously allocated Command Payload. It
6068 is used to set identifier for command when resending Command
6071 * Added silc_command_payload_encode_payload to encode Command
6072 Payload buffer from SilcCommandPayload structure.
6074 * Added silc_argument_payload_encode_payload to encode Argument
6075 payload buffer from SilcArgumentPayload structure.
6077 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Changed WHOIS command to support router connection on server side.
6080 The whois request is always sent to router unless the server is
6081 standalone server. After server has received the reply from the
6082 router will it send the reply to the client.
6084 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6085 broadcast received broadcast packet. The function is used only
6086 by router. The broadcast packet is always sent to the router's
6089 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6090 render given ID to printable string, for log files for example.
6092 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Made basic router to router connections working. At least they
6095 can now connect to each other but nothing really works the way
6096 they are supposed - yet.
6098 * Added new initiator token to RouterConnection configuration
6099 file in silcd/serverconfig.[ch]. It is used to tell whether we
6100 are the initiator to the remote router or whether we'll expect
6101 the other end to connect.
6103 * Moved registering of listener task to silc_server_init, hence
6104 the server starts listenning as soon as it is run, even if it
6105 does not have connections to other routers. Let's see how well
6108 * Changed default connection retry timeouts for more suitable in
6111 * Removed cipher and such arguments from silc_idlist_add_client
6112 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6113 Added new function silc_idlist_add_data to add the keys and stuff
6116 * Added SilcIDListData structure and added it to SilcClientEntry
6117 and SilcServerEntry as their first field in the structure. This
6118 way we can explicitly cast the ID entries to the SilcIDListData
6119 structure and get common data for the entries. In past, we had
6120 to first check what type of connection it is and then cast it to
6121 correct ID entry type. Now, we can directly cast the opaque
6122 pointer to the SilcIDListData (no matter what ID entry it actually
6123 is) and get the data needed.
6125 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6128 in some circumstances even if threre were timeout tasks, though not
6129 IO tasks, but tasks anyway. Now fixed.
6131 * Defined SilcServerConnection structure to hold connection specific
6132 stuff about directly connected servers and routers. The definition
6133 is currently in silcd/server_internal.h. I thought about having
6134 a bit more important role fro this struct but for now it is used
6135 only when connecting to other server (or router actually).
6137 * Added connecting retry support in server when connecting to
6138 router(s). The retry feature implement exponential backoff
6139 algorithm. Also, added SilcServerParams structure to hold default
6140 parameters for server. For now, it include these retry settings
6141 and are hard coded. After server is moded to be as Silc Server
6142 Library this structure will be more important.
6144 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Changed client librarys channel->clients table to SilcList and
6147 changed code accordingly.
6149 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6151 * Changed client's channel table to SilcList and changed code
6152 accordingly. Also changed SilcChannelClientEntry to include back-
6153 pointer to the channel so that client entry can use that structure
6154 as list as well and we have fast cross-reference to the channel.
6155 This change dramatically decreased the complexity of channel
6156 handling with client entry and vice versa (removed one extra
6157 loop when searching for channel entry from many functions).
6159 * Changed server->sim from table to SilcDList and changed code
6162 * NAMES command can now be used from user interface. It will show
6163 the user list on the channel, neatly.
6165 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6166 Code now saves realname of the user if it becomes available.
6168 * Renamed configure.in to configure.in.pre and made ./prepare
6169 script to automatically add correct version string to
6170 configure.in which it creates from configure.in.pre.
6172 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * NAMES command reply now shows users mode with the nickname when
6177 * Moved silc_client_ch[u]mode[_char] functions from
6178 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6179 place sucks, they are utility functions and should be in some
6182 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6184 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6187 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6191 * Added TRQ (efficient deque and list library) into lib/trq. This is
6192 a very good list library that is currently used in the SILC. Defined
6193 SilcList API over the library because I didn't like the API very
6194 much. See lib/trq/silclist.h for the API and examples of how to
6195 use the API. Fixed various places in the code to use the new
6196 SilcList API. The SilcList is meant for lists that has a structure
6197 already defined as a list. It is not suitable to add just some
6198 context to the list (in TRQ, the context is the list actually).
6200 So, I defined SilcDList that can be used for the purpose where
6201 predefined list structure does not exit. This can be used as
6202 such list. Now some context just can be added to the SilcDList.
6203 Currently this list is not used in the SILC just yet, though there
6204 are a lot places where this can replace dynamically allocated
6205 tables and I will fix these places, later, to use SilcDList.
6206 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6207 and use TRQ internally).
6209 Also fixed some annoying warning messages that the original TRQ
6210 code generated. Also minor changes to TRQ's Makefile.in.
6212 * Added support for querying by Client ID to both WHOIS and
6213 IDENTIFY commands into server, as required by the protocol.
6215 * Removed method function pointers from SilcBuffer structure. They
6216 weren't used to anything and just increased the context size for
6217 no good reason. This change also made silc_buffer_alloc and
6218 silc_buffer_free functions inline functions.
6220 * Disabled command flooding detection support until it's fixed so
6221 that it accepts commands in but does not execute them more than once
6224 * Added silc_net_localhost(), to return local hostname, into
6225 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6226 that must be initialized before calling silc_client_init.
6228 * Added new function: silc_server_send_notify_on_channels to send
6229 notify messages to all channels client has joined. It is assured
6230 that the message is sent only once per client.
6232 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6233 lib/silcutil/silcutil.[ch] as silc_format function. The new
6234 function is generic and is used by server as well, not only by
6235 the logging routines.
6237 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6238 the provided version string was not acceptable. Added new function:
6239 silc_ske_check_version into lib/silcske/silcske.h. The function
6240 must be implemented by the application (client or server) and it
6241 does not reside in the SKE library. The function checks the version
6242 string remote end sent.
6244 * Added back pointers (to opaque context and to SilcSocketConnection)
6245 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6247 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6248 duplicate packet context structure.
6250 * Changed `notify' client operation to send same arguments as client
6251 receives from server except for ID's. ID's are mapped to correct
6252 ID entry and that is returned. Also, if channel entry is not sent
6253 by server but the notify is for channel the channel entry is sent
6254 to application (otherwise application doesn't know that it is for
6255 channel (library gets it from packet's Destination ID)).
6257 * Added silc_client_remove_from_channels into client library to
6258 remove a client from all channels it has joined to. Used when
6259 received SIGNOFF notify from server. Added also new function
6260 silc_client_replace_from_channels to replace old ID entry with
6261 new ID entry on all channels. Used when received NICK_CHANGE
6264 * Fixed ID Cache list handling in silc_idlist_get_client in
6265 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6266 to get (or query) client by ID.
6268 * Updated TODO list.
6270 * Added connection authentication status message defined by the
6271 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6272 support for these into the code in client and server side.
6274 * Added generic function silc_client_send_command to send any command
6275 with variable argument list. Application should use this function
6276 to send commands if the command functions provided by the library
6277 does not suite for the application's user interface needs.
6279 * Added new `failure' client operation. Application is notified about
6280 received failure packet if client is executing a protocol. In this
6281 case the protocol's execution has failed.
6283 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6284 is required by the protocol.
6286 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6287 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6290 * Added status flag to SilcSKE object to indicate realtime status
6291 of the SKE protocol.
6293 * Application receives now exactly same command reply arguments as
6294 the library receives from server. However, if ID is received the
6295 corresponding ID entry is returned to the application (eg. Client
6296 ID is mapped to correct SilcClientEntry entry and that is returned).
6297 Changed command_reply client operation due to this change.
6299 * Changed all ID's in commands and in command replys as ID Payloads.
6300 Change affected both client and server side codes.
6302 All ID's sent in SILC network (with execption of ID's in SILC
6303 Packet header) are sent in ID Payload to support variable length
6306 * Server now notifies nick changes and notifies all clients on
6307 the channels about the new nickname (about the new Client ID,
6310 * Implemented CMODE command to change channel modes. Supports all
6311 channel modes defined by the protocol specs except ban and invite
6312 lists. (Also, private channel key mode is supported but support for
6313 setting private channel key in client is missing, thus, this mode
6314 has no effect on client side (except that server requires that the
6315 client uses private channel key and normal channel traffic does not
6318 Also, invite mode works per se, but INVITE command does not work
6319 yet correctly, so you can set channel as invite only channel but
6320 inviting clients to the channel does not work (it is yet to be
6321 thought what's the best way to do it).
6323 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6324 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6325 Implemented CUMODE command to change user's mode on the channel.
6326 Supports all modes defined by the protocol specs.
6328 * Added NAMES command reply to return users modes on the channel.
6330 * Removed unnecessary and slow ciphers from lib/silccrypt.
6332 * Set SO_KEEPALIVE option to connection sockets by default.
6334 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6336 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6337 redefined the Notify Payload into protocol specs.
6339 * Added silc_id_payload_parse_id to get ID directly from raw
6342 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6345 accept searching by Client ID as well.
6347 * Added support for LEAVE and SIGNOFF notify types in client library.
6349 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6350 to parse ID Payload from raw data.
6352 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * Added flags parameter into silc_ske_assemble_security_properties
6355 function in lib/silcske/silcske.[ch].
6357 * Changed notify client operation to fit better for notify messages
6358 sent by server. The notify payload received from server is now
6359 passed to the application (after parsing it to SilcNotifyPayload).
6360 It is application's responsibility to retrieve the arguments
6361 from the payload and show the message the way it wants. The message
6362 sent by server is implementation specific.
6364 * Changed public keys to comply with the protocol specification.
6365 Old public keys are not supported anymore and are not compatible.
6367 * Removed nickname from Channel Payload as the latest draft removed
6368 it. The client must resolve the nickname from the NAMES command
6369 reply received when it joined the channel.
6371 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6373 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6375 * Fixed some errors in protocol specification drafts.
6377 * Created lib/silccore/silcnotify.c to implement Notify Payload
6378 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6379 generic payloads described by protocol specifications. The file
6380 includes implementations for ID Payload and Argument Payload.
6382 * Changed Command Payload implementation to use the new Argument
6383 Payload. Changed command_xxxx_payload to command_payload_xxxx
6384 to comply with SILC coding conventions.
6386 * Added suppport for Argument Payload handling in Notify Payload
6387 implementation as protocol requires it. Added the new support
6388 into server and client lib as well.
6390 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6392 * Added support for multiple nicknames on same channel. [n] is
6393 added locally to the nickname if there are more than one same
6394 nicknames on the channel.
6396 * Server now sends all nicknames that matched WHOIS request.
6397 Client also shows the list received from server.
6399 * Added TOPIC command to client side. User can now set and show
6400 current topic on channel.
6402 * Added MOTD command to client and server. Also, server sends the
6403 motd when client connects to the server.
6405 * Changed version strings to comply ISO 8601.
6407 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * Fixed protocol error handling in client library. It should now
6410 cope even if the SKE fails for some reason.
6412 * Made new protocol specification drafts for submitting to IETF.
6414 * Implemented TOPIC command to server in silcd/command.c.
6416 * Added two new notify types into lib/silccore/silcnotify.h:
6417 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6418 notify nickname change and topic setting/change on a channel.
6420 * API change of command_reply operation in client library. The
6421 application gets now the status type received from server as well.
6423 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6427 * Cras fixed and optimized the packet handling even further and
6428 it should work now. Minor change to the prototype of function
6429 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6431 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6433 * Added new function into lib/silcutil/silcschedule.[ch]:
6434 silc_schedule_with_fd to select() a specified fd. The function
6435 returns after timeout expires or data arrives or goes. The
6436 function is used by packet routines to wait that all data is
6437 received from network.
6439 * Fixed data reading from network in lib/silccore/silcpacket.c.
6440 The code now assures that all data is read from the fd and then
6441 continues packet processing. This was a bug fix since the code
6442 used to drop some data in some circumstances.
6444 * Added new function into lib/silcclient/client.[ch]:
6445 silc_client_start_key_exchange to start key exchange after
6446 connection has been established to server. The code internally
6447 now uses this funtion but its main purpose was to provide it
6448 for applications that perform their own connecting. After
6449 application has created a connection it merely calls this
6450 function to start the key exchange between client and server.
6451 The library takes care of everything else after that.
6453 Updated also lib/silcclient/README to explain the usage of
6456 * Do not send to application information that connection has
6457 been established. Application gets notified it by connect
6460 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6462 * Applied cras's patch to add silc_schedule_one function. The
6463 function runs scheduler once and returns.
6465 * Fixed the scheduler after cras messed it up. The timeout
6466 handling works now as it's supposed to work.
6468 * Added into lib/silccore/ silcnotify.h to include notify
6469 message types support. Changed silc_server_send_notify*
6470 functions, in server.[ch], to support those new notify types.
6471 Added the support for the notify types into client library,
6472 as well. Added new notify client operation into ops.h in
6475 * Changed silc_server_packet_send_to_channel to send normal
6476 packets instead of just channel message packets. The function
6477 is now used to send the notify packets to channels. It is not
6478 used to send channel message packets anymore, as server never
6481 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6482 va_arg()s as it seems to require it nowadays. I guess, if SILC
6483 is compiled with older va_arg() the new code should work anyway.
6485 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6487 * Splitted core library. Core library (lib/silccore) includes
6488 now only SILC protocol specific core (and common) components.
6489 Created new utility library (lib/silcutil) that includes more
6490 generic purpose stuff. The stuff for util library was taken
6491 from the old core library. This was minor and easy split.
6493 * Created SILC Client Library (lib/silcclient) that includes
6494 implementation of the SILC client without user interface. This
6495 was major move from silc/ directory. The code has been changed
6496 so that it is transparent towards the user interface. The
6497 silc/ directory includes now the same user interface as before
6498 and it uses the new client library. Read lib/silcclient/README.
6499 Basicly, the client library performs everything else related
6500 to SILC except user interface handling. Also, configuration
6501 files are considered to be part of user interface and library
6502 does not handle them.
6504 This change also changed a lot of structures, function naming etc.
6505 Most important change was that SilcClientWindow object was
6506 renamed to SilcClientConnection in the client library. Created
6507 also new file lib/silcclient/ops.h. Also added new files
6508 silc/local_command.[ch] and silc/client_ops.[ch].
6510 All these changes were made to make it easier for user interface
6511 designers to create what ever user interface for the SILC client
6514 It is also expected that the server will be moved to lib
6515 directory as well and SILC Server Library will be created;
6516 sometimes in the future.
6518 * Removed Local commands from lib/silccore/silccommand.h as
6519 they are application specific and new client library does not
6520 handle any of those anymore.
6522 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6523 old client implementation in silc/.
6525 * Added support for callback functions in SILC_LOG_* macros.
6526 Application can now set its own callbacks that will be called
6527 instead of using the default functions that will always print
6528 the debug messages to stderr (or stdout). Also, debugging can
6529 now be disabled by setting silc_debug to FALSE and re-enabled by
6530 setting it to TRUE. Note, that logging will still work even
6531 if debugging is disabled.
6533 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6534 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6535 silc_log_reset_debug_callbacks.
6537 * To enable debugging in silc client one must give now -d
6538 option on command line.
6540 * Changed silc_schedule_init to automatically allocate task queues
6541 if they are not allocated before calling it.
6543 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Added GMP 3.1 into math library.
6547 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6550 a channel in SILC network. The packet is used by servers and
6551 routers to notify other routers that user has left a channel.
6552 This little feature was missing until now. Added the feature
6553 to protocol specification as well.
6555 Added functions: silc_server_send_remove_channel_user and
6556 silc_server_remove_channel_user into server.[ch].
6558 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6559 lib/silccore/silcpacket.h. However, they are not implemented
6562 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6564 * Fixed joining to a channel and sending channel messages
6565 between server and router. The channel message sending should
6566 now work inside a cell.
6568 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * Fixed the private message sending between server and router.
6571 The private message sending should now work inside a cell.
6573 * Added silc_server_replace_id into server.[ch] to replace
6574 existing ID in the SILC network.
6576 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6577 and silc_idlist_replace_server_id into idlist.[ch] in server.
6579 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6581 * Fixed the server to server connections. Server can again now
6582 connect to router. Router to router connections probably does
6585 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6587 * Added dynamic protocol registering support. Now protocols can
6588 registered and unregistered on the fly. Patch by cras.
6590 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6592 * Added lib/contrib directory to hold routines that some platforms
6593 don't have but are needed by SILC.
6595 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6596 into lin/contrib to provide getopt() and getopt_long() for
6597 those who don't have it.
6599 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Added AWAY command to client. When away message is set and
6602 client receives a private message packet the client automatically
6603 replies to the sender with the away message.
6605 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6606 bug seemed to be the cause of recent problems when compiling
6609 * Added version detection support to SKE protocol specification
6610 and added the new changes to the SKE implementation as well.
6611 There were other minor changes in the SKE protocol as well.
6613 Many changes in lib/silcske/silcske.[ch] and in
6614 lib/silcske/payload.[ch].
6616 * Added ^U functionality, clear input line. Patch from cras.
6618 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * Mainly small bugfixes on core library. Fixed some debugging
6621 logging and buffer overflow in silclog.c.
6623 * Updated config.sub and config.guess on the distribution tree.
6625 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6627 * Added command lagging support in server. Client may execute
6628 commands now only once in two seconds.
6630 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6632 * Optimized packet reception. MAC computation and checking is now
6633 also more optimized. A lot previously duplicated code is now
6634 used as generic by both client and server.
6636 * Fixed key pair generation in clientutil.c
6638 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6640 * Added into lib/silccore/silcbufutil.[ch] new function;
6641 silc_buffer_realloc.
6643 * Moved generic packet sending/encryption functions to
6644 lib/silccore/silcpacket.[ch] from client and server. Some
6645 rewriting of the functions.
6647 * Moved all generic packet reception/decryption functions to
6648 lib/silccore/silcpacket.[ch] from client and server. The
6649 packet processing is now much cleaner in both client and server.
6650 These were major changes in both client and server.
6652 * Created many common functions in server to do packet sending.
6653 Previously code were duplicated a lot, this has been removed
6656 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Rewrote major parts of the ID cache system. Don't know
6659 whether it is better now or not but at least the API is more
6662 * Major rewrite on ID cache stuff on client because of the ID
6663 cache API changes. Added idlist.c to client.
6665 * Also major rewrite on ID cache stuff on server as well.
6666 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6667 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6668 in hand, instead they are all put into the ID cache system now.
6669 All server_idlist_* routines uses ID cache now instead of
6670 traversing its own lists (those lists does not exist anymore).
6671 SilcIDList though still exists. Also, SilcXXXEntry's are
6674 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Finally made the SKE implementation compliant to the protocol
6677 specification. All mp integers are now binary encoded as
6678 opposed being HEX encoded.
6680 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6683 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6684 functions: silc_[encode/decode]_pem. Also added function
6685 silc_encode_pem_file to PEM encode with newlines ('\n') for
6688 * SILC public keys are now encoded either PEM or binary. Same
6689 option is for private keys as well. By default private keys
6690 are binary encoded and public keys PEM encoded. Silly HEX
6691 encoding were removed.
6693 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6694 function to create fingerprints.
6696 * Fixed a bug in SHA1; does not change the original data anymore.
6698 * Partly implemented INFO command on client and server side.
6699 Fixed CLEAR command. Changes to SERVER command; show current
6700 server(s) when giving command without arguments. Added
6701 VERSION command to client.
6703 * Added check to server that unregistered connections cannot
6704 execute commands (unless it is specificly allowed).
6706 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6708 * Fixed screen refresh.
6710 * Fixed channel joining bug from client. On some circumstances
6711 client tried to join to a channel it had already joined.
6713 * Added public key verification process into client's protocol.c.
6714 The client now verifies the public key from user and saves
6715 it into ~./silc/serverkeys/ directory.
6717 Added into: clientutil.[ch]: silc_client_verify_server_key.
6719 * Changed SKE protocol's silc_ske_initiator_finish function
6720 to accept callback function that verifies the received public
6721 key. Removed old silc_ske_verify_public_key function.
6723 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6725 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6726 silc_pkcs_private_key[_data]_set.
6728 * Made the password and public authentication more cleaner in
6729 server's protocol.c.
6731 * Removed historic and obsolete protocol `channel_auth' from
6732 both client and server.
6734 * Removed wrong way of sending command status messages from
6735 server to client in server's command.c. The old way violated
6736 protocol specification.
6738 Changes to silccore/silccommand.[ch]: removed
6739 silc_command_encode_status_payload -> not needed anymore,
6740 changed silc_command_encode_payload_va to accept extra
6741 argument on variable argument list. The argument type must
6742 now be provided to the function. Also, added new function:
6743 silc_command_encode_reply_payload_va which is same as
6744 normal command_encode_payload_va except command status type
6745 is provided as extra argument.
6747 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6749 * Added ~./silc directory handling. The directory includes the
6750 public and private keys for the client.
6752 Added silc_client_check_silc_dir, silc_client_create_identifier
6753 and silc_client_load_keys.
6755 * Implemented SILC protocol compliant public key. Added public
6756 and private key saving to and loading from files.
6758 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6759 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6760 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6761 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6762 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6764 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6765 silc_pkcs_load_[public/private]_key.
6767 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Added silc_server_get_route (route.[ch]) to get connection
6770 data for the fastest route for given ID.
6772 * Implemented INVITE command on client and server. The command
6773 were re-defined in the SILC Protocol Specification and the
6774 implementation now complies with the specification.
6776 * Implemented PING command on client and server.
6778 * Implemented NAMES command on client and server. The server side
6779 supports currently only normal server not router server yet.
6780 Some changes to NAMES definition in SILC protocol specification.
6782 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6784 * Implemented LEAVE command on client and server.
6786 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6787 again. This change was made to the protocol as well. Server
6788 should not violate the protocol specification anymore.
6790 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6792 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6793 was tested. SOCKS4 was not but should work anyway.
