1 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Do not print the warning about log files not being initialized
4 more than once to avoid excess logging. Affected file is
5 lib/silcutil/silclog.c.
7 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
8 the SIM copying in make install in Makefile.am.pre.
10 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
12 * Rewritten silclog APIs. Globally interesting changes follows:
13 silc_log_set_files() changed to silc_log_set_file().
14 silc_log_set_callbacks() changed to silc_log_set_callback().
15 ROBOdoc documented silclog header file.
16 SilcLogCb now returns bool to wether inihibit the default
17 handler or not (to keep the old behaviour return always TRUE).
18 The new APIs should also fix the problem of the
19 silcd_error.log file that was written in the current directory.
22 Log files streams will remain opened after silc_log_set_file()
23 call, means less CPU usage notably on high traffic servers.
24 File streams are now full buffered, and flushed to the disk
25 every 5 minutes, lesses HD activity and CPU usage.
26 Messages can be redirected, allowing admins to configure
27 one single logfile for all server messages.
28 the silc_log_quick global variable to activate fast-logging.
29 Affected files lib/silcutil/silclog.[ch]
31 * Changed some code to conform new silclog APIs. Affected
32 files are doc/example_silcd.conf.in, silcd/server.c
33 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
36 * Fixed a memory leak that could occur in some situations.
37 Affected file silcd/serverconfig.c.
39 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
41 * Added the silc_client_del_client to remove the client from
42 all channels as well. Affected file lib/silcclient/idlist.c.
44 * Fixed the client library to correctly remove the client
45 from all channels when the client entry is being destroyed.
46 Affected file lib/silcclient/client_notify.c, command.c.
48 * Added auto-nicking support to the client library. If the
49 applicatio now sets client->nickname it will be sent to the
50 server after connecting by the library. This way for example
51 SILCNICK (or IRCNICK) environment variables will have effect
52 and always change the nickname automatically to whatever
53 it is wanted. Affected file lib/silcclient/client.[ch].
55 * Renamed silc_server_command_bad_chars to the
56 silc_server_name_bad_chars and moved it to the
57 silcd/server_util.[ch]. Added also new function
58 silc_server_name_modify_bad to return nickname that
59 includes bad characters as new nickname without those
60 bad characters. This check and modify is now used in
61 silc_server_new_client when the username is initially set
62 as nickname, so it must be checked to be valid nickname.
63 Affected file silcd/packet_receive.c.
65 * The nickname length is now taken from the packet for real
66 and not trusted to strlen() since it clearly can return
67 wrong length for nickname including bad characters. This
68 also applies to channel names. Affected file silcd/command.c.
70 * Removed the lib/silcsilm/modules directory. Modules are now
71 compiled into the lib/silcsim. Fixed the copying of the
72 modules to follow symbolic links in Makefile.am.pre.
74 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
76 * Fixed silc_string_regexify list creation. Fixes bugs with
77 BAN and INVITE commands in server. The affected file is
78 lib/silcutil/unix/silcunixutil.c.
80 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
82 * Removed the command destructor entirely from the server's
83 command and command reply routines. It is not needed, and
84 its usage was buggy and caused crashes. Affected files are
85 silcd/command[_reply].[ch].
87 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
89 * Cancel protocol and NULL sock->protocol if timeout
90 occurred during protocol. Affected file silcd/server.c.
92 * Cancel protocol timeouts always before calling the final
93 callback, to assure that after final callback is called
94 no other state will be called for the protocol anymore.
95 Affected file silcd/protocol.c.
97 * Print error log if incoming connection configuration could
98 not be found. Affected file silcd/server.c.
100 * Fixed JOIN command to correctly save the founder mode
101 to the client on normal SILC server, when the channel
102 was created by the router. Affected file silcd/command.c.
104 * Fixed LIST command (hopefully) to send correct reply
105 packets. Affected file silcd/command.c.
107 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
109 * The silc_packet_receive_process now returns FALSE if the
110 read data was invalid packet, and TRUE if it was ok.
112 The server now checks that if unauthenticated connection
113 sends data and its processing fails the server will close
114 the connection since it could be a malicious flooder.
116 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
118 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
120 * Make sure the warning about error opening a log file is
121 printed only once and not everytime it fails (produces
122 too much useless log). Affected file lib/silcutil/silclog.c.
124 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
126 * Made the silc_server_daemonise() function more readable.
127 Affected file silcd/server.c.
129 * Pid file is now optional, the user may comment it out from
130 the config file. Removed define SILC_SERVER_PID_FILE, we
131 don't need a default any longer. Affected file
132 configure.in.pre, lib/Makefile.am.pre.
134 * Make some use of the pid file. The server now dies at startup
135 if it detects a valid pid file on his path. The server would
136 die anyway in this circumstance, because of the bind() failure.
137 Affected file silcd/silcd.c.
139 * No longer compiling lib/dotconf.
141 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
143 * Fixed JOIN command parsing not to crash. Affected file
144 lib/silcclient/command.c.
146 * Fied the NICK_CHANGE notify to add the new client entry
147 even it is resolved. This removes an <[unknown]> nick
148 thingy bug in the client. Affected file is
149 lib/silcclient/client_notify.c.
151 * Do not try to allocate 0 bytes (efence does not like it)
152 in lib/silccore/silccomand.c when encoding payload.
154 * Do not take IRCNICK as nickname in Irssi SILC client since
155 it is not possible to set nickname before hand connecting
156 the server (TODO has an entry about adding auto-nicking
159 * Changed the silc_server_command_pending to check whether
160 there already exists an pending entry with the specified
161 command, command identifier and pending callback. This is
162 to fix IDENTIFY and WHOIS related crashes that may register
163 multiple pending commands with same identifier. Affected
164 file silcd/command.c.
166 * Fixed the server to reconnect to the router even if it
167 was already reconnecting and EOF was received. This to
168 fix a possibility that the server wouldn't ever try to
169 auto-reconnect to the router. Affected file silcd/server.c.
171 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
173 * Fixed the server's password authentication to use the
174 length of the locally saved password, and not the one
175 sent in the packet. Affected file silcd/protocol.c.
177 * Fixed same password authentication problem in the
178 Authentication Payload handling routines in
179 lib/silccore/silcauth.c.
181 * Yet another password authentication problem fixed with
182 channel password handling in silcd/command.c.
184 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
186 * If first character of string in silc_parse_userfqdn is '@'
187 then do not parse it. Affected file is
188 lib/silcutil/silcutil.c.
190 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
192 * Fixed minor bug in IDENTIFY command reply sending, which
193 caused various weird problems during JOIN when it was
194 resolving names for users. Affected file silcd/command.c.
196 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
198 * Fixed the IDENTIFY command reply sending to chech better valid
199 clients. It was possible to send incomplete list of replies.
200 Affected file silcd/command.c.
202 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
204 * Added silc_client_command[s]_[un]register functions now to
205 dynamically register the commands in client library. Removed
206 the static table of commands. This allows the client library
207 to call commands without causing the application to know about
208 what commands library has called.
210 Removed the INFO command reply kludge to detect when the command
211 was called by library. Now library use its own command reply
212 function for INFO command.
214 Added function silc_client_command_call to call a command.
215 Application can use it to call command, not access the structure
218 Now all commands that are sent by the client library (not
219 explicitly sent by application) use own command reply functions.
221 Affected files around lib/silcclient/ and in
222 irssi/src/silc/core/.
224 * Fixed the WHOIS command reply sending to chech better valid
225 clients. It was possible to send incomplete list of replies.
227 Fixed the WHOIS and IDENTIFY to send the request to router
228 if normal server did not do it and did not find any results.
230 Affected file silcd/command.c.
232 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
234 * Moved the internal data from SilcClient context into its
235 own file, not accesible to application. Affected files
236 lib/silcclient/client.h and lib/silcclient/client_internal.h,
237 and other files in client library.
239 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
241 * Added doc/examples installation target in Makefile.am.pre.
244 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
246 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
247 commands the found client entry will be removed from the
248 cache, after notifying application about the error. Affected
249 file lib/silcclient/command_reply.c.
251 * Changed the /MSG to check for exact nickname user gave, and
252 not let `nick' match `nick@host' if it is only one found. Now,
253 user must type the exact nickname (like nick@host2) even if
254 there are no more than one same nicks found. This is to avoid
255 a possibility of sending nickname to wrong nickname since
256 `nick' could match `nick@host'. Affected file is
257 irssi/src/core/silc-servers.c.
259 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
261 * Do not print "you are now server operator" or similar when
262 giving /away command. Affected files are
263 irssi/src/silc/core/client_ops.c, silc-servers.h.
265 * Made the silc_server_command_pending_error_check to send
266 the same command reply payload it received back to the
267 original sender of the command. This way all arguments
268 that was received by the server will be received by the
269 client too. Affected file silcd/command.c.
271 * Added the silc_idcache_add to return the created cache entry
272 to a pointer. Affected file lib/silccore/silcidcache.[ch].
274 * Add global clients to expire if they are not on any channel.
275 This is because normal server will never know if they signoff
276 if they are not on any channel. The cache expiry will take
277 case of these entries. This is done by normal servers only.
278 The affected files are silcd/command_reply.c,
279 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
281 * If server receives invalid ID notification for WHOIS or
282 IDENTIFY and the ID exists in the lists, it is removed.
283 Affected file silcd/command_reply.c.
285 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
286 in client then client entry that it matches is searched and
287 the nickname is printed on the screen for user. Affected
288 file irssi/src/silc/core/client_ops.c.
290 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
292 * Use cache entry expire time in the LIST command reply to
293 purge old entries from the cache after the LIST command
294 reply has been received. This way we don't have non-existent
295 entries in the cache for too long. Affected file is
296 silcd/command_reply.c.
298 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
300 * If we are normal server, and we've not resolved client info
301 in WHOIS or IDENTIFY from router, and it is global client,
302 we'll check whether it is on some channel. If it is not
303 then we cannot be sure about its validity and will resolve it
304 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
305 file silcd/command.c.
307 * Search channel by name (if possible) rather than by ID
308 in IDENTIFY command's command reply. Affected file is
309 silcd/command_reply.c.
311 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
313 * Distribute to the channel passphrase in CMODE_CHANGE notify.
314 Updated specs and implemented it. Affected file silcd/command.c,
315 silcd/packet_send.c and silcd/packet_receive.c.
317 * Implemented the <founder auth> payload handling in the JOIN
318 command. If provided all conditions for channel joining
319 except requirement to provide correct passphrase can be
320 overrided by the channel founder. Updated the protocol specs.
321 Affected file silcd/command.c.
323 Added support for founder auth in JOIN command in client
324 library. Fixed the parsing of the JOIN command now to support
325 all options as they should be. The affected file is
326 lib/silcclient/command.c.
328 * Optimized the WHOIS and IDENTIFY commands to send the request
329 to router only if it includes nicknames or other names. If
330 they include only IDs then check the local cache first before
331 routing. Affected file is silcd/command.c.
333 * Added channels topic announcements. Affected file is
334 silcd/packet_receive.c and silcd/server.c.
336 * Fixed the silc_server_send_notify_topic_set to really destine
337 the packet to channel. Affected file silcd/packet_send.c.
339 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
340 library. Affected file lib/silcclient/client_notify.c.
342 * Added UMODE announcements. Affected file silcd/server.c.
344 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
346 * Memory leak fixes in:
348 lib/silcutil/silcsockconn.c
349 lib/silcske/silcske.c
352 lib/silccrypt/silcpkcs.c
353 lib/silccore/silccommand.c
354 lib/silccore/silcidcache.c
359 * ROBOdoc documented the lib/silcske/groups.h file and a
360 bit changed the interface for better.
362 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
364 * Update the client entry context in the ID cache after
365 nick change. Affected file lib/silcclient/command.c.
366 Fixes the CUMODE command when regaining founder privileges,
367 and a little WHOIS problem.
369 * Fixed silc_net_gethostbyname to correctly call the
370 inet_ntop. Affected file lib/silcutil/silcnet.c.
372 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
374 * Added IPv6 support checking to the configure.in.pre, added
375 also --enable-ipv6 option to override the check. Affected
376 file configure.in.pre.
378 * The silc_thread_create now calls the start function
379 directly if threads support is not compiled in. Removes
380 ugly #ifdef's from generic code. Affected files are
381 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
383 * Added silc_net_gethostby[name/addr]_async to asynchronously
384 resolve. Affected files are lib/silcutil/silcnet.[ch].
386 * Added support for rendering IPv6 based server, client and
387 channel IDs. Affected file lib/silcutil/silcutil.c.
389 * Added support for creating IPv6 based server IDs. Affected
390 file is silcd/serverid.c.
392 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
394 * Added silc_net_gethostby[addr/name] into the
395 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
396 routines. Added silc_net_is_ip[4/6]. Affected file is
397 lib/silcutil/unix/silcunixnet.c. All routines that take
398 address as argument now supports both IPv4 and IPv6 addresses.
400 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
402 * Fixed LIST command reply sending in server. Affected file
405 * Server now sends the kicker's client ID in the KICK notify
406 to the kicked client. Affected file silcd/command.c.
408 * The client library now parses the kickers client ID and
409 UI displays it. Affected files lib/silcclient/client_notify.c
410 and irssi/src/silc/core/silc-channels.c, module-formats.c.
412 * Made all payload parsing function prototypes consistent.
413 They all take now const unsigned char * and uint32 pair as
414 the payload data instead of SilcBuffer. Changes all around
415 the source tree. Other unsigned char* -> const unsigned char*
416 changes around the tree as well.
418 * Optimized SFTP client and server packet sending not to
419 allocate new buffer for each packet but to recycle the
420 first allocated buffer. Affected files are
421 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
423 * Optimized the SFTP client to use SilcList instead of
424 SilcDList for requests, because it is faster. Affected file
425 is lib/silcsftp/sftp_client.c.
427 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
428 into lib/silccore/silcid.[ch].
430 Renamed silcpayload.[ch] into silcargument.[ch].
432 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
434 * If client entry is deleted with active key agreement
435 session, abort the session.
437 The silc_client_abort_key_agreement now calls the completion
438 callback with new SILC_KEY_AGREEMENT_ABORTED status.
440 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
443 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
445 * Don't use __restrict in older GCC's. Affected file is
446 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
448 * silc_net_localhost now attempts to reverse lookup the
449 IP/hostname. Affected file lib/silcutil/silcnet.c.
451 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
452 command. It can be used to gain founder privileges at
453 the same time when joining the channel.
455 Defined that the SILC_NOTIFY_TYPE_KICKED send the
456 kicker's client ID as well. Updated protocol specs.
458 Defined that the server must send SILC_COMMAND_IDENTIFY
459 command reply with error status to client who sent
460 private message with invalid client ID.
462 Updated the protocol specification.
464 * Added silc_server_send_command_reply to send any
465 command reply. Affected file silcd/packet_send.[ch].
467 * Added silc_id_payload_encode_data to encode ID payload
468 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
470 * The server now send IDENTIFY command reply with error
471 status if client ID in private message is invalid. Affected
472 file silcd/packet_receive.c.
474 * Save the server key file with server's IP address in
475 the filename instead of hostname. The affected file is
476 irssi/src/silc/core/client_ops.c.
478 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
480 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
483 * Added libtool support for compiling shared objects in
484 lib/silcsim. Affected file configure.in.pre and
485 lib/silcsim/Makefile.am. Original patch by cras.
487 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
489 * Pid file configuration, and server's config file fixes
490 patch by toma. Updated CREDITS file.
492 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
494 * Fixed silc_client_channel_message to not try to decrypt
495 the message twice if it resolved the destination client
496 information. This could cause of dropping one channel
497 message. Affected file lib/silcclient/client_channel.c.
499 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
501 * Added silc_client_run_one into lib/silcclient/silcapi.h and
502 lib/silcclient/client.c. This function is used when the SILC
503 Client is run under some other scheduler, or event loop or
504 main loop. On GUI applications, for example this may be
505 desired to used to run the client under the GUI application's
506 main loop. Typically the GUI application would register an
507 idle task that calls this function multiple times in a second
508 to quickly process the SILC specific data.
510 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
512 * Fixed silc_server_drop() for dropping the supplementary
513 groups as well, this could cause a security hole on some
516 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
518 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
521 * Write PID file after dropping privileges. Added -F option
522 to run server on foreground. A patch by debolaz.
523 Affected files silcd/server.c, silcd/silcd.c.
525 * Fixed MOTD to return the MOTD file server name. Affected
526 file silcd/command.c.
528 * Added INFO command reply handling to the Irssi SILC Client.
529 Affected file irssi/src/silc/core/client_ops.c.
531 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
533 * Fixed the silc_idcache_list_* routines to really support
534 the dynamic list. Fixes a crash. Affected file is
535 lib/silccore/silcidcache.c.
537 * Fixed the LIST command reply to really call LIST command's
538 pending callbacks. Affected file silcd/command_reply.c.
540 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
542 * Update conn->local_entry->nickname after giving NICK
543 command. Affected file lib/silcclient/command.c.
545 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
547 * Added the [pid] option to the silcd configuration file
549 Affected files: serverconfig.[ch] and silcd.c
551 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
553 * Save fingerprint in WHOIS command reply in server.
554 Affected file silcd/command_reply.c.
556 * Fixed NICK commands pending callback registration.
557 Affected file lib/silcclient/command.c.
559 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
561 * Use ++server->cmd_ident when sending commands in server,
562 instead of random number. Affected file silcd/command.c.
564 * Fixed GETKEY command reply to call actually GETKEY pending
565 command callbacks. Affected file silcd/command_reply.c.
567 * A bit stricter check for nicknames. Check for same nickname
568 in NICK command also. Affected file silcd/command.c.
570 * Do not call INFO command everytime client ID changes, only
571 during first connecting. Affected file lib/silcclient/client.c.
573 * Set the new nickname only after successful command reply for
574 NICK command is returned by server. Affected file
575 lib/silcclient/command.c.
577 * Remove nicknames from nicklist during server_signoff notify.
578 Should fix /NAMES bit more. The affected file is
579 irssi/src/silc/core/silc-channels.c.
581 * Added `fingerprint' field to the SilcIDListData in the
582 silcd/idlist.h to hold the fingerprint of the client's
585 Send the fingerprint of the client's public key in WHOIS
588 Affected files silcd/command.c, and silcd/idlist.[ch].
590 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
591 create fingerprint from given data.
593 * Show the fingerprint of the client's public key in WHOIS.
594 Affected files irssi/src/module-formats.[ch] and
595 irssi/src/silc/core/client_ops.c.
597 * Format the multiple same nicknames also during JOIN and
598 NICK_CHANGE notifys. Affected file is
599 lib/silcclient/client_notify.c.
601 * Do not print error on screen for invalid private message
602 payload since it can come if someone is sending private
603 messages with wrong key. Affected file
604 lib/silccore/silcprivate.c.
606 * Fixed multiple concurrent /PING crash. Affected file
607 lib/silcclient/command.c.
609 * Changed the wrong ID encoding. All IP addresses must be
610 in MSB first order in encoded format. They were encoded
611 wrong and was in LSB format. Affected files are
612 silcd/serverid.c, lib/silcutil/silcutil.c.
614 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
616 * Call the `connect' client operation through the scheduler
617 in case of error. Affected file lib/silcclient/client.c.
619 * Call the `failure' client operation even if the error
620 occurred locally during a protocol. Affected file is
621 lib/silcclient/protocol.c.
623 * Added support of sending LIST command to router from normal
624 server. This way normal server can get list of all channels
625 in the network too. Fixed the channel list sending in the
626 server too. Affected files are silcd/command.c, and
627 silcd/command_reply.[ch].
629 * Added silc_server_update_channels_by_server and
630 silc_server_remove_channels_by_server. They are used during
631 disconnection of primary router and in backup router protocol.
632 Affected file silcd/server_util.[ch], silcd/server.c and
633 silcd/server_backup.c.
635 * Fixed channel adding to global list in IDENTIFY command
636 reply in server. Affected file silcd/command_reply.c.
638 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
640 * If the incoming packet type is REKEY or REKEY_DONE process
641 that packet always synchronously. Fixes yet another MAC
642 failed error on slow (dialup) connections. Affected file
643 lib/silcclient/client.c and silcd/server.c.
645 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
647 * Call check_version SKE callback for initiator too. Affected
648 file lib/silcske/silcske.c.
650 * Implemented fix for security hole found in the SKE that was
651 fixed in the specification few days back; the initiator's
652 public key is now added to the HASH value computation.
653 Added backwards support for the old way of doing it too, for
654 old clients and old servers. Affected file is
655 lib/silcske/silcske.c.
657 * Enabled mutual authentication by default in SKE. If initiator
658 is not providing mutual authentication the responder will
659 force it. This will provide the proof of posession of the
660 private key for responder. The affected files are
661 lib/silcclient/protocol.c and silcd/protocol.c.
663 * Do not cache anymore the server's public key during SKE.
664 We do mutual authentication so the proof of posession of
665 private key is done, and if the server is authenticated in
666 conn auth protocol with public key we must have the public
667 key already. Affected file silcd/protocol.c.
669 * Added new global debug variable: silc_debug_hexdump. If
670 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
671 file lib/silcutil/silclog.[ch].
673 * Fixed compilation warning due to char * -> const char *.
674 Affected files lib/silcutil/silcnet.h, and
675 lib/silccore/silcauth.[ch].
677 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
679 * Fixed CMODE command when new channel key was created. If
680 the creation failed the old key was removed. Next time giving
681 same command would crash the server since the old key was
682 freed already. Affected file silcd/command.c.
684 * Fixed the silc_server_announce_get_channels to not crash
685 on reconnect. Affected file silcd/server.c.
687 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
689 * Added silc_log_set_debug_string function to set a regex
690 string to match for debug output. Only the function names,
691 or filenames matching the given debug string is actually
692 printed. This way it is possible to filter out those debug
693 strings that user is not interested in.
695 Fixed a bug in silc_string_regexify.
697 Affected files lib/silcutil/silclog.[ch], and
698 lib/silcutil/unix/silcunixutil.c.
700 * Changed the -d options in both server and Irssi SILC client
701 to take the debug string as argument. Affected files
702 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
704 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
706 * Added silc_hash_babbleprint to create a Bubble Babble
707 Encoded fingerprint. The encoding is developed by Antti
708 Huima (draft-huima-babble-01.txt), and it creates human
709 readable strings out of binary data. Affected file
710 lib/silccrypt/silchash.[ch].
712 * Print the babble print now in addition of fingerprint as well
713 in Irssi SILC client. Affected files are
714 irssi/src/fe-common/silc/module-formats.[ch],
715 irssi/src/fe-common/silc/core/client_ops.c.
717 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
719 * Fixed a security problem found in SKE. The initiator's
720 public key too is now added to the HASH hash value creation
721 which is signed by the responder to create the SIGN value.
722 This will prevent anyone in the middle to lie to the responder
723 about the initiator's public key. If this is done now, the
724 man in the middle will get caught. Updated the protocol
727 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
729 * Better installation directory handling. Configure module
730 paths and other paths automatically to example_silc* files
731 in doc/. A patch by toma.
733 * Fixed compiler warning from MPI library, and from SILC RNG.
736 * Added SILC_SERVER_PID_FILE to define the pid file for server.
737 It can be configured with ./configure. A patch by toma.
739 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
741 * Find correct make to use in prepare-clean. A patch by
742 toma. Affected file prepare-clean.
744 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
746 * Added irssi variables use_auto_addr, auto_bind_ip,
747 auto_bind_port and auto_public_ip.
749 * Changed the interface for silc_client_send_key_agreement
750 in lib/silcclient/silcapi.h
754 irssi/src/silc/core/silc-core.c
756 lib/silcclient/silcapi.h
757 irssi/src/silc/core/silc-channels.c
758 lib/silcclient/client_keyagr.c
761 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
763 * Added silc_pkcs_public_key_compare to compare two
764 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
766 * Check that the client who set the founder mode on the
767 channel is the same client that is giving the founder
768 mode to itself. It is done by comparing the saved public
769 key (it is saved even in the authentication is passphrase).
770 Affected file silcd/command.c.
772 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
774 * Do not process packet for disconnected socket connection.
775 Affected file lib/silccore/silcpacket.c.
777 * Process the DISCONNECT packet through scheduler in the
778 client library. Affected file lib/silcclient/client.c.
780 * Fixed the silc_client_packet_parse to not to increase
781 the packet sequence number if the conn->sock and the
782 current socket connection is not same. This can happen
783 for example during key agreement when the conn includes
784 multiple socket connections (listeners). Affected file
785 lib/silcclient/client.c.
787 * The sender of the file transfer request now provides also
788 the pointer (listener) for the key exchange protocol. If
789 the listener cannot be created then it sends empty key
790 agreement and lets the receiver provide the listener.
792 Added `local_ip' and `local_port' arguments to the
793 silc_client_file_send. If they are provided they are used,
794 if not then it will attempt to find local IP address, if
795 not found or bind fails then the remote client will provide
798 Affected files are lib/silcclient/client_ftp.c and
799 lib/silcclient/silcapi.h.
801 * Extended the FILE SEND command to support defining the
802 local IP and port for key exchange listener. They are
803 optional. Affected file irssi/src/silc/core/silc-servers.c.
805 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
807 * Defined to WHOIS command reply the sending of fingerprint
808 of the client's public key (if the proof of posession of the
809 corresponding private key is verified by the server).
810 Updated to the protocol specification.
812 * Added support of receiving the client's public key's
813 fingerprint in command reply in client library. Affected
814 file is lib/silcclient/command_reply.c, and
815 lib/silcclient/idlist.[ch].
817 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
819 * Do not send over 128 chars long nickname to the server
820 in NICK command. Affected file lib/silcclient/command.c.
822 * Do not send over 256 chars long channel names to the server
823 in JOIN command. Affected file lib/silcclient/command.c.
825 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
827 * Assure that silc_server_close_connection cannot be called
828 twice for same socket context. Affected file is
831 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
833 * Send error message to application if opening file for
834 writing during file transfer fails. Affected file is
835 lib/silcclient/client_ftp.c.
837 Remove all file transfer sessions for a client that we're
838 removing from ID cache.
840 Affected file is lib/silcclient/client_ftp.c.
842 * Fixed silc_net_addr2bin to return correct address. Affected
843 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
845 * Fixed file transfer session removing on signoff notify.
846 Affected file irssi/src/silc/core/silc-servers.c.
848 * Added the SilcClientFileError to be returned in the monitor
849 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
850 Affected file lib/silcclient/silcapi.h.
852 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
854 * Fixed a crash in silc_client_ftp_free_sessions and
855 silc_client_ftp_session_free_client. Affected file
856 lib/silcclient/client_ftp.c.
858 * Added `disabled' field in the SilcChannelEntry in the server
859 to indicate if the server entry is disabled. Affected file
860 silcd/idlist.h, silcd/command[_reply].c.
862 * SILC server adds now /var/run/silcd.pid everytime it is
863 started. Affected file silcd/silcd.c.
865 * Added silc_server_packet_send_clients to send a packet to
866 the provided table of client entries. Affected file
867 silcd/packet_send.[ch].
869 * Fixed a crash in client resolving in client_prvmsg.c in
870 client library. Affected file lib/silcclient/client_prvmsg.c.
872 * Do not actually remove the client directly from ID cache
873 during SERVER_SIGNOFF, but invalidate it. This way we
874 preserve the WHOWAS info for the client. Affected file
877 * Fixed SERVER_SIGNOFF notify handling in the server. The
878 server is now able to process incoming SERVER_SIGNOFF notify
879 for a server that it doesn't even know about. It will remove
880 the clients provided in the notify. Affected file
881 silcd/packet_receive.c.
883 * Check for partial packet in data queue after every packet that
884 was found from the queue. Return and wait for more data if
885 there is partial data in queue. Affected file is
886 lib/silccore/silcpacket.c.
888 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
890 * Added SilcClietFileError enum to indicate error in
891 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
892 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
893 Affected files lib/silcclient/silcapi.h and
894 lib/silcclient/client_ftp.c.
896 * Check that newsize in silc_buffer_realloc is larger than
897 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
899 * Added better monitor of file transfers. It now monitors
900 key agreement protocol during the file transfer too. Added
901 error reporting too. Affected files
902 irssi/src/silc/core/silc-servers.c,
903 irssi/src/fe-common/silc/module-formats.[ch].
905 * Wrote a help file for FILE command.
907 * Added silc_rng_global_get_byte_fast to get not-so-secure
908 random data as fast as possible. Random data is read from
909 /dev/urandom if available and from the SILC RNG if not
910 available. It is used in padding generation. Affected file
911 lib/silccrypt/silcrng.[ch].
913 * All packets in client library are now processed synchronously.
914 Optimized packet processing a lot. Affected file
915 lib/silcclient/client.c.
917 * All server connection packets are processing synchronously
918 now in server, to optimize packet processing. Affected file
921 * Include files are installed now only in Toolkit distribution
922 if make install is given. Affected files: all Makefile.am's.
924 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
926 * Assure that silc_client_notify_by_server_resolve does not
927 resolve the client information multiple times. If it cannot
928 be found by the first it cannot be found at all. Affected
929 file lib/silcclient/client_notify.c.
931 * Fixed WHOWAS command reply calling. Affected file
932 lib/silcclient/command_reply.c.
934 * Removed all references to silc_idlist_get_client from the
935 Irssi SILC client since that call is internal call used by
936 the library. The Irssi SILC client will use now client
937 retrieval functions found in silcapi.h.
939 * Fixed a bug in resolving nickname info before sending
940 private message. It used freed memory. Affected file
941 irssi/src/silc/core/silc-servers.c.
943 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
945 * Assure my_channels statistics cannot go negative in server.
946 Affected files silcd/server.c, silcd/server_util.c.
948 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
952 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
954 * Win32 Toolkit changes. Affected files
955 win32/silc.dsw, win32/libsilc/libsilc.def,
956 win32/libsilcclient/libsilc.def,
957 lib/silcutil/silcutil.c, and
958 lib/sftp/sftp_fs_memory.c.
960 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
962 * Added silc_net_localip to return local host's IP address.
963 Affected file lib/silcutil/silcnet.[ch].
965 * If key exchange or rekey protocol is active for a connection
966 parse all packets syncronously since there might be packets
967 in packet queue that we are not able to process without first
968 processing packets before them. Affected file silcd/server,
969 lib/silcclient/client.c.
971 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
972 whether library should continue processing the packet.
973 Affected file lib/silccore/silcpacket.h.
975 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
976 SilcSFTPMonitorData to SFTP server to monitor various
977 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
978 lib/silcsftp/sftp_server.c.
980 * Added silc_file_size to return file size. Affected file
981 lib/silcutil/silcutil.[ch].
983 * Implemented the file transfer support for the client library.
984 Added preliminary support for simple client to client one-file
985 transmission. Affected file lib/silcclient/client_ftp.c,
986 lib/silccilent/client.[ch].
988 * Added new local command FILE to the Irssi SILC Client.
989 It is used to perform the file transfer. It has subcommands
990 SEND, RECEIVE, SHOW and CLOSE. Affected files
991 irssi/src/silc/core/client_ops.c,
992 irssi/src/silc/core/silc-server.[ch].
994 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
996 * Relay the SILC_PACKET_FTP in the server. Affected files
997 silcd/server.c and silcd/packet_receive.c.
999 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * Renamed silc_file_read and silc_file_write to functions
1002 silc_file_readfile and silc_file_writefile. Added function
1003 silc_file_open and silc_file_close. Affected files
1004 lib/silcutil/silcutil.[ch].
1006 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * Resolve the client info when received private message or
1009 channel message for a client which nickname we don't know.
1010 Affected files lib/silcclient/client_prvmsg.c and
1011 lib/silcclient/client_channel.c.
1013 * Do not crash in /KEY if client is not connected. Affected
1014 file irssi/src/silc/core/silc-channels.c.
1016 * Added SilcClientStatus field to the SilcClientEntry in the
1017 lib/silcclient/idlist.h.
1019 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1020 is incomplete and is being resolved, it won't be resolved
1023 Make sure also that USERS command reply does not resolve
1024 twice information. Affected file is
1025 lib/silcclient/command_reply.c.
1027 Make sure that silc_client_get_clients_by_list does not
1028 resolve twice same information.
1030 * Check for valid client->id in the silc_server_free_client_data.
1031 Affected file silcd/server.c.
1033 * Fixed /GETKEY nick@server not to crash if the server entry
1034 is not found. Affected file lib/silcclient/command.c.
1036 * Fixed the silc_server_check_cmode_rights to check the
1037 requested modes correctly. Affected file silcd/command.c.
1039 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Better checks for non-printable chars in nick added.
1042 Affected file silcd/command.c.
1044 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1046 * Call the silc_server_udpate_servers_by_server in the
1047 primary router that comes back online in the backup resuming
1048 protocol. Otherwise it routes packets wrong. Affected file
1049 silcd/server_util.[ch], silcd/server_backup.c.
1051 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1053 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1054 lib/silcutil/silcbuffmt.[ch].
1056 * Redefined the SILC packet header to include the padding
1057 length. Affected file lib/silccore/silcpacket.[ch].
1059 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1060 length for maximum padding up to 128 bytes). Affected
1061 file lib/silccore/silcpacket.h.
1063 * Removed all backwards support for old 0.5.x MAC thingies.
1064 The SILC packet header change makes it impossible to be
1065 backwards compatible.
1067 * Send the ENDING packet with timeout in the backup resuming
1068 protocol. This is to assure that all routers has connected
1069 to the primary router. Affected file silcd/server_backup.c.
1071 * Changed the RNG to take the first IV from random data. It
1072 used to take it from zero actually. Changed the RNG also
1073 to use /dev/urandom during session. /dev/random is used
1074 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1076 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1078 * Changed the SILC packet header to have the first two bytes
1079 (the packet length) encrypted. Affected files aroung the
1080 code tree, lib/silccore/silcpacket.[ch]. Removed the
1081 SilcPacketCheckDecrypt callback. It is not needed anymore
1082 since the silc_packet_receive_process will determine now
1083 whether the packet is normal or special.
1085 * Implemented the unidirectional MAC keys. Affected files
1086 lib/silcske/silcske.c, silcd/protocol.c and
1087 lib/silcclient/protocol.c.
1089 * Implemented the packet sequence number to the MAC computation.
1090 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1091 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1092 lib/silcclient/protocol.c.
1094 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1096 * Allow backup router to announce servers. All servers
1097 announced by backup router are added to the global list
1098 automatically. Update hte server's socket to our primary
1099 router also when backup router announces a server.
1100 Affected file silcd/packet_receive.c.
1102 * Do not update the client->router in the function
1103 silc_server_udpate_clients_by_server if the client is on
1104 global list. We might fail to find any specific server
1105 for locally connected clients and local cell clients. They
1106 should still use the `from' and not `to' as client->router.
1107 This fixes backup router resuming protocol. Affected file
1108 silcd/server_util.c.
1110 * Decrease channel statistics count only if the channel
1111 deletion worked. Affected files are silcd/server.c and
1112 silcd/server_util.c.
1114 * Added silc_server_update_servers_by_server to update origin
1115 of all server entries. Used during backup router protocol.
1116 Affected files silcd/server_util.[ch], silcd/server.c. and
1117 silcd/backup_router.c.
1119 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1120 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1121 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1122 lib/silccrypt/silchmac.c.
1124 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1126 * Assure that router cannot reroute the same channel message
1127 to the sender. Affected file silcd/packet_receive.c.
1129 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1131 * Made better checks that the channel message is not sent
1132 to the router it came from. Affected file is
1133 silcd/packet_send.c. Fixed memory leak too.
1135 * Announce informations for incoming router connection, but
1136 only after checking if it is replaced by backup router.
1137 Affected file silcd/packet_receive.c.
1139 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1141 * Fixed the backup resuming protocol to work in multiple
1142 router environment. Affected file silcd/server_backup.c.
1144 * Route packet only to one router in the function
1145 silc_server_packet_send_to_channel. Affected file is
1146 silcd/packet_send.c.
1148 * Fixed silc_server_send_notify_dest to set the broadcast
1149 flag. Fixed the silc_server_send_notify_topic to actually
1150 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1151 Affected file silcd/packet_send.c.
1153 * Changed the SFTP Filesystem interface. Changed the
1154 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1155 the filesystem operation function. The SilcSFTPFilesystem
1156 is now a context that is allocated by all filesystem allocation
1157 functions and it already includes the operations structure
1158 and filesystem specific context. It is given as argument
1159 now to the silc_sftp_server_start. This made the interface
1160 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1161 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1163 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1165 * Changed the backup router adding and getting interfaces
1166 in the server. The router that will be replaced by the
1167 specified backup router is now sent as argument. Affected
1168 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1171 * Added silc_net_addr2bin_ne to return the binary form of
1172 the IP address in network byte order. Affected files
1173 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1175 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1177 * Check for existing server ID in silc_server_new_server
1178 and in silc_server_connect_to_router_final and remove the
1179 old entry if it exists. Affected file silcd/packet_receive.c,
1182 * Send the channel message always to only one router, either
1183 in upstream or downstream. Affected file is
1184 silcd/packet_send.c.
1186 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1188 * Wrote the definition of the backup resuming protocol to the
1189 protocol specification.
1191 * Removed one redundant channel key generation from normal
1192 server during joining procedure. Removed one redundant
1193 channel key sending from server to router during joining
1194 procedure. Affected file silcd/command.c.
1196 * Made minor bugfixes to the backup router resuming protocol.
1197 Affected file silcd/server_backup.c, server.c.
1199 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1201 * Added --disable-asm configuration option. Affected files
1202 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1205 * Implemented the backup resuming protocol that is used to
1206 resume the primary router position in the cell after the
1207 primary router comes back online. Affected files
1208 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1209 and silcd/server_util.[ch].
1211 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1213 * Sleep two (2) seconds after sending QUIT command to server.
1214 Affected file lib/silcclient/command.c.
1216 * Assure that if outgoing data buffer is pending do not force
1217 send any data. Affected file silcd/packet_send.c.
1219 * Assure that if outgoing data buffer is pending do not force
1220 send any data. Affected file lib/silcclient/client.c.
1222 * Implemented the backup router support when the primary router
1223 goes down. The servers and routers can now use the backup
1224 router as new primary router without loosing connectivity.
1226 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1229 in the server to indicate disabled entry. All data read
1230 from the connection will be ignored and no data is sent
1231 for entry that is disabled. Affected files are
1232 silcd/idlist.h, silcd/server.c.
1234 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1236 * Created SFTP client and server test programs in the
1237 lib/silcsftp/tests directory.
1239 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1241 * Implemented memory filesystem (virtual filesystem) for
1242 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1245 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1247 * Implemented the SFTP (SSH File Transfer Protocol) to the
1248 lib/silcsftp. It includes SFTP client and SFTP server
1251 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Moved lib/silccore/silcprotocol.[ch] to the
1254 lib/silcutil library.
1256 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1257 take variable argument list pointer as argument. Affected
1258 file lib/silcutil/silcbuffmt.[ch].
1260 * Added silc_buffer_set function that is used to set data
1261 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1262 Affected file lib/silcutil/silcbuffer.h.
1264 * Changed various routines in the core library to use the new
1265 silc_buffer_set instead of allocating new buffer only for
1268 * Added 64-bit value formatting and unformatting support to the
1269 silc_buffer_[un]format routines. Affected file is
1270 lib/silcutil/silcbuffmt.[ch].
1272 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1273 to includes/bitmove.h.
1275 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Fixed channel user mode saving in client library. Affected
1278 file lib/silcclient/command[_reply].c.
1280 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1282 * Defined the file transfer to the SILC Protocol. Added
1283 new packet type SILC_PACKET_FTP and defined File Transfer
1284 Payload. The mandatory file transfer protocol is SFTP
1285 (SSH File Transfer Protocol). Affected file in addition
1286 of the internet draft is lib/silccore/silcpacket.h.
1288 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1289 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1290 is used as part of backup router protocol when the primary
1291 router of the cell is back online and wishes to resume
1292 the position as primary router.
1294 * Redefined the MAC generation keys in the protocol. The
1295 same key is not used anymore in both direction. Both
1296 direction will now use different keys for sending and
1297 receiving. This fixes a potential security flaw. This
1298 change causes incompatibilities in the protocol.
1300 * Redefined also the MAC computation from the packet.
1301 An packet sequence number is now added to the MAC
1302 computation. This prevents possible replay attacks against
1303 the protocol. This change too causes incompatibilities
1306 Added `sequence' field to the SilcPacketContext to hold
1307 the current sequence number for the packet.
1309 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1311 * Added `created' field to the SilcIDListData in the file
1312 silcd/idlist.h to indicate the time when the entry was
1315 * Added `created' field to the SilcChannelEntry too. Affected
1316 file silcd/idlist.h.
1318 * Added `creation_time' aguments to all the announcement functions
1319 in the server. If it is provided then only the entries that
1320 was created after the provided time frame are actually
1321 announced. Affected file silcd/server.[ch].
1323 * The protocol says that the Channel ID's IP address must be
1324 based on the router's IP address. Added check for this in
1325 the silc_server_new_channel when processing incoming New Channel
1326 Payload. Affected file silcd/packet_receive.c.
1328 * Print out the correct version with --version in SILC client.
1329 Affected file irssi/src/silc/core/silc-core.c.
1331 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1333 * Fixed WHOWAS command to check for completnes of the client
1334 entry always, not just when the command is coming from client.
1335 Affected file silcd/command.c.
1337 * Added new function silc_server_packet_queue_purge to purge the
1338 outgoing data queue to the network. After the function returns
1339 it is guaranteed that the outgoing packet queue is empty.
1340 Affected file silcd/packet_send.[ch].
1342 * Purge the outgoing packet queue in the rekey protocol's final
1343 callback to assure that all rekey packets go to the network
1344 before quitting the protocol. Affected file silcd/server.c.
1346 * Added silc_client_packet_queue_parse as similar function as
1347 in server to the client library. The affected file is
1348 lib/silcclient/client.c.
1350 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Splitted silcd/server.c and created silcd/server_util.[ch]
1353 for utility functions.
1355 * Added new socket flag SILC_SF_DISABLED to indicate that the
1356 connection is open but nothing can be sent to or received from
1357 the connection. Affected file lib/silcutil/silsockconn.[ch].
1358 The checking for disabled socket is checked in the low level
1359 silc_socket_write and silc_socket_read functions.
1361 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Allow only nicknames and channel names that fits into the
1364 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1366 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * When processing JOIN command reply in server check that if
1369 the channel exists in our global list we'll move it the local
1370 list. Affected file silcd/command_reply.c.
1372 * Fixed the check whether client is joined on the channel already
1373 in JOIN command. Affected file lib/silcclient/command.c.
1375 * Fixed the JOIN command reply to check whether the channel
1376 already exists. Affected file lib/silcclient/command_reply.c.
1378 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Added silc_ske_status_string to map the SKE error numbers
1381 to readable strings. The affected files are
1382 lib/silcske/silcske[_status].[ch].
1384 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Do not show the private channels on the WHOIS channel list
1387 as it is not allowed by the protocol. The affected file is
1390 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Assure that the packet length digged from the actual packet
1393 is something sensible in the silc_packet_decrypt_rest_special
1394 in lib/silccrypt/silcpacket.c.
1396 * Free and NULL the allocated pointer in silc_hmac_alloc if
1397 the HMAC allocation fails. The affected file is
1398 lib/silccrypt/silchmac.c.
1400 * Print the selected security properties to the log files in
1401 the server. Affected file silcd/protocol.c.
1403 * Add SKE's reference counter even if calling the completion
1404 callback manually. Otherwise it goes negative, although it
1405 does not cause any problems. The affected file is
1406 lib/silcske/silcske.c.
1408 * Remove the client entry with short timeout after giving the
1409 KILL command. Affected file lib/silcclient/command.c.
1411 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1412 case all found clients are already disconnected (WHOWAS would
1413 found them) in the server. Affected file silcd/command.c.
1415 * Update the last_receive (time of last data received) to be
1416 updated only when received private or channel message so that
1417 the idle time showed in WHOIS makes more sense.
1419 * Added boolean field `valid' in to the SilcClientEntry in the
1420 client library to indicate whether the entry is valid or not.
1421 This fixes the nickname change bug on channel when changing
1422 the nickname to be same than the old (like nick to Nick) the
1423 nickname formatter doesn't set the new nick anymore to Nick@host.
1424 Affected file lib/silcclient/idlist.[ch].
1426 * Now actually fixed the nickname changing on disconnection.
1427 Added new function silc_change_nick to the Irssi SILC Client.
1428 Affected file irssi/src/silc/core/client_ops.c,
1429 irssi/src/silc/core/silc-nicklist.[ch].
1431 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * Check that the public key exists in the GETKEY command before
1434 trying to encode it. Affected file silcd/command.c.
1436 * Print some notifications on received public keys with GETKEY
1437 command in the Irssi SILC Client. Affected files are
1438 irssi/src/fe-common/silc/module-formats.[ch],
1439 irssi/src/silc/core/client_ops.c.
1441 * Use IDENTIFY command to resolve the server information in the
1442 GETKEY command instead of INFO command. Affected file
1443 lib/silcclient/command.c.
1445 * All command reply functions in the client library now calls
1446 the pending command reply callbacks even if an error has
1447 occurred. The server has done this a long time and now it was
1448 time to move the client library to this as well. Now all
1449 errors can be delivered back to the pending command reply
1450 callbacks if necessary. Affected files are
1451 lib/silcclient/command[_reply].[ch].
1453 * Change the nickname on disconnection back to the username
1454 because in reconnect the server will enforce it to it anyway.
1455 Affected file irssi/src/silc/core/silc-servers.c.
1457 * Fixed a config file parsing bug in the Irssi SILC client.
1458 Affected file irssi/src/silc/core/clientconfig.c.
1460 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * When printing the channel mode on JOIN, verify that the
1463 channel key and channel's HMAC are valid. Affected file
1464 irssi/src/silc/core/client_ops.c.
1466 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1468 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1469 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1470 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1472 * Removed channel key rekey task deleting from the function
1473 silc_server_save_channel_key. Affected file silcd/server.c.
1474 Added explicit timeout task context instead that is used to
1475 delete the task if we are registering a new task before the
1476 new task has elapsed.
1478 * When channel key rekey occurs the client library now saves
1479 the old channel key for a short period of time (10 seconds) and
1480 is able to use it in case some is still sending channel
1481 messages encrypted with the old key after the rekey. Affected
1482 file lib/silcclient/[idlist.h|client_channel.c].
1484 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1486 * Added check to the silc_server_new_id_real to not accept
1487 new ID if it is the sender's own ID. Affected file is
1488 silcd/packet_receive.c.
1490 * Assure that we do not announce ourself or the one we've
1491 sending our announcements when we're router and are announcing
1492 servers to our primary router. Affected file silcd/server.c.
1494 * Fixed silc_server_command_identify_check_client to assemble
1495 correct WHOIS packet. It send corrupted WHOIS packet and
1496 caused problem with router to router connections. Affected
1497 file silcd/command.c.
1499 Fixed also silc_server_command_whois_check the same way
1500 as for the IDENTIFY command.
1502 * Added new SilcIDListStatus to the server in the SilcIDListData
1503 structure. The status now includes the current status of
1504 the entry (like registered, resolved etc.). Affected file
1505 silcd/idlist.[ch]. Defined a bunch of different status types
1506 as well. This replaced the old boolean registered field as well.
1508 Added resolve_cmd_ident field to the SilcClientEntry structure
1509 too so that if the entry is for example being resolved so
1510 another command may attach to the same pending command reply
1511 without requiring to resolve the same entry again. This concept
1512 should optimize the WHOIS and the IDENTIFY resolving under
1513 heavy load by taking away unnecessary resolving for entries
1514 that are being resolved already.
1516 Added support for adding multiple pending commands for one
1517 command idenfier. Affected file silcd/command[_reply].[ch].
1519 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1520 before deleting the data. Otherwise the hash table will have
1521 freed data in comparison functions. Affected file is
1522 silcd/command_reply.c.
1524 * Fixed silc_idlist_replace_client_id to add the new entry to
1525 the cache with NULL nickname. Otherwise there will be invalid
1526 memory as the nickname after the nickname is freed. Affected
1527 file silcd/packet_receive.c.
1529 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1530 saved into wrong slots because the previous number of entries
1531 was not taken into account. Affected file silcd/idlist.c.
1532 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1534 * If we are router and we receive JOIN notify to a channel that
1535 does not have any users then notified client is marked as the
1536 channel founder, as it is it. The affected file is
1537 silcd/packet_receive.c
1539 * Added to the extended hash table API's table_del_*ext functions
1540 the destructor as argument too, so that the caller can decide
1541 which destructor to use or whether to use destructor at all.
1542 Affected file lib/silcutil/silchashtable.[ch].
1544 * Fixed ID Cache purging. It actually deleted the entries from
1545 the hash table after the data was freed. The hash table ended
1546 up comparing freed memory. The affected file is
1547 lib/silccore/silcidcache.c.
1549 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Fixed Irssi SILC client's KILL command's HELP syntax.
1553 * The USERS command now resolves the detailed user information
1554 if the userinfo field is missing. Affected file is
1555 lib/silcclient/command_reply.c.
1557 * Do not print error in silc_file_read if the read file does
1558 not exist. Just silently return NULL. Affected file is
1559 lib/silcutil/silcutil.c.
1561 * Fixed the silc_log_output to not wine about NULL filename
1562 and to not create some bogus " " filename. Affected file is
1563 lib/silcutil/silclog.c.
1565 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Fixed various printing bugs on the user interface in the
1568 Irssi SILC Client. Minor changes that were forgotten from
1571 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Fixed the configure.in.pre and the compilation and distribution
1574 environment to support the new autoconf 2.52. That version is
1575 now required to compile the CVS trunk.
1577 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1579 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1580 to generally parse user@fqdn format strings. Affected file
1581 lib/silcutil/silcutil.c.
1583 * Added nickname_format and nickname_force_format fields to the
1584 SilcClientParams structure. The first one defines the format
1585 for the nicknames that the library will enforce if the receives
1586 multiple same nicknames. The second one is boolean value and
1587 can be used to force the library to always enforce the format
1588 to the nicknames regardles whether there are multiple nicknames
1589 or not. This configurable formatting was employed to flexibly
1590 support accessing multiple nicknames from the user interface.
1591 The userinterface can now set the nicknames to what ever format
1592 they prefer. Affected file lib/silcclient/silcapi.h.
1594 Added function silc_client_nickname_format to the file
1595 lib/silcclient/idlist.c. It performs the nickname formatting.
1597 Added new field `hostname´ to the SilcClientEntry context.
1598 It holds the hostname of the client. Affected file is
1599 lib/silcclient/idlist.h.
1601 * Irssi SILC Client sets the nicknames in nick@hostn format.
1602 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1603 irssi/src/silc/core/silc-core.c.
1605 The WHOIS printing now also shows both the real nickname and
1606 the formatted nickname so that user knows how to access the
1607 user if there are multiple same nicknames cached. Affected
1608 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1609 printing formatting too to take the hostname now as a separate
1610 argument. The Affected file is
1611 irssi/src/fe-common/silc/modules-formats.[ch].
1613 * Changed the silc_client_get_clients_local to accept the formatted
1614 nickname as argument. It accepts the real nickname too but the
1615 formatted nickname can be used to find the true entry from
1616 multiple entries. Affected file lib/silcclient/silcapi.h and
1617 lib/silcclient/idlist.c.
1619 * Added nickname_format_parse field to the SilcClientParams.
1620 It is a callback function provided by the application to parse
1621 the nickname out of the formatted nickname string. The library
1622 calls it to get the nickname from the formatted string. Since
1623 the application generally knows better the format of the nickname
1624 string it parses it instead of the library, even though library
1625 encodes the formatted string. If the callback function is not
1626 provided then the library will use the string as is. The
1627 affected file is lib/silcclient/silcapi.h.
1629 * All the nickname strings passed to the client library in
1630 commands are now expected to be formatted nickname strings.
1631 If the command does not support the formatted nickname string
1632 it will assume that the sent string is the actual nickname.
1633 Affected file lib/silcclient/command.c.
1635 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Added public key authentication support to OPER and SILCOPER
1638 commands in the client library. Affected file is
1639 lib/silcclient/command.c.
1641 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1643 * Changed the get_auth_methdod client operation to be asynchronous.
1644 It can be async if the application resolves the authentication
1645 method from the server during the negotiation. Added new
1646 SilcGetAuthMeth completion callback that the application will
1647 call after resolving the authentication method.
1649 Added function silc_client_request_authentication_method that
1650 the application can use to resolve the authentication method
1651 from the server. Added also SilcConnectionAuthRequest callback
1652 that the library will call after the server has replied. The
1653 application can call this function if it does not know the
1654 current authentication method.
1656 Affected files are lib/silcclient/client.c and
1657 lib/silcclient/silcapi.h.
1659 * The Irssi SILC client now automatically resolves the authentication
1660 method incase any configuration information is not present (and
1661 currently there never is). The affected file is
1662 irssi/src/silc/core/client_ops.c.
1664 * Fixed public key authentication from the client library.
1665 Affected file lib/silcclient/protocol.c. Changed also the
1666 protocol specification about the public key authentication in
1667 the connection authentication protocol. The actual data to be
1668 signed is now computed with a hash function before signing.
1670 * Fixed the public key authentication from the server as well.
1671 Affected file silcd/protocol.c.
1673 * Removed the mlock()'s from the memory allocation routines.
1674 Affected file lib/silcutil/silcmemory.c. The ./configure does
1675 not check anymore for the mlock(). Affected file is
1678 * Fixed USERS command in server to allow the execution of the
1679 command for private and secret channels if the client sending
1680 the command is on the channel. Affected file silcd/command.c.
1682 * Fixed silc_client_get_clients_local to return the clients
1683 count correctly. It could return wrong value. Affected file
1684 lib/silcclient/idlist.c.
1686 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1689 types. The assembler optimizations seemed not to like 64-bit
1690 data types. The assmebler optimizations thus are now enabled
1691 also for BSD systems as opposed to only enable them for Linux.
1693 * Do not check for threads at all on BSD systems. Affected
1694 file configure.in.pre.
1696 * Removed -n and -h options from the Irssi SILC Client since
1697 they are not used in silc.
1699 * Fixed the prime generation to assure that the first digit
1700 of the generated random number is not zero since our conversion
1701 routines does not like number strings that starts with zero
1702 digit. If zero digit is seen the random number is regenerated.
1703 This caused some corrupted RSA keys when the zero first digit
1704 was met. Affected file lib/silcmath/silcprimegen.c.
1706 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Fixed WIN32 configuration in the ./configure script.
1709 Fixed to include xti.h on environments that has it.
1710 Patches by Carsten Ilchmann and andrew.
1712 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Changed the silc_id_create_client_id to be collision
1715 resistant. It is now assured that there cannot be created
1716 two same client ID's. I suspect that some weird bugs in
1717 the server were actually caused by duplicate Client IDs.
1718 Affected file silcd/serverid.[ch]. A router receiving
1719 new ID now also assures and informs the sending server
1720 if the ID caused collision.
1722 * Changed the silc_id_create_channel_id to also assure that
1723 there are no collisions.
1725 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1727 * Statement about ignoring the Mutual Authentication flag when
1728 performing rekey with PFS was a bit misleading. It is ignored
1729 if it was set in the initial negotiation, it cannot be even
1730 set in the rekey. Fixed in the ke-auth draft. Started the
1731 new versions of the protocol drafts in the doc/.
1733 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Fixed a bug in silc_client_command_identify_save when saving
1736 new channel information. The channel name was no duplicated
1737 and caused crash on exit. Affected file is
1738 lib/silcclient/command_reply.c.
1740 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * Fixed the getkey command handling in the server. Send just
1743 empty OK reply to the sender if the key could not be fetched
1744 (but everything else was ok, like the key just was not available).
1745 Changed the public key parameter to optional in the protocol
1746 specs so that empty OK reply can be sent. Affected file
1749 Added a message to Irssi SILC client to tell to user if the
1750 server did not return a public key.
1752 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1754 * Fixed a channel key regeneration bug. It registered new
1755 timeout tasks exponentially until all system resources were
1756 used. Affected file silcd/server.c.
1758 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Added the SILC Document generator to the scripts/silcdoc.
1761 It can be used to generate the Toolkit Reference Manual out
1762 of the source tree. Internally it will also use the RoboDoc
1763 generator now imported in util/robodoc.
1765 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1767 * Added couple of return's in rekey protocol if error orccurred
1768 during the protocol. The execution must be terminated.
1769 Affected file silcd/protocol.c. Also, terminate the protocol
1770 always with timeout.
1772 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * The client's Client ID was created initally from the wrong
1775 nickname (it could have been in format nick@host) in the
1776 silc_server_new_client. Affected file silcd/packet_receive.c
1778 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * Added some SILC_LOG_ERROR's to various error conditions
1781 if client could not be added to ID cache. Affected files
1782 silcd/packet_receive.c and silcd/server.c.
1784 * When client's sock->user_data is freed, NULL also the
1785 client->router and client->connection pointers. Added check
1786 for these pointers being NULL to various places around the
1787 code. Affected file silcd/server.c.
1789 * Added client->data.registered == TRUE checks to various
1790 places around the code to assure that unregistered client's
1791 are not handled when it is not allowed. Affected file
1794 * Added `bool registered' fields to all
1795 silc_idlist_[server|client]_get_* routines to indicate whether
1796 the fetched client needs to be registered or not. Affected
1797 file silcd/idlist.[ch].
1799 * Add your own entry as registered to the ID cache in the
1800 server. Affected file server.c.
1802 * Fixed a bug in silc_server_new_server. The SilcServer was
1803 set as the new server's context instead of SilcServerEntry.
1804 This naturally caused some weird bugs.
1806 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Do not delete the channel rekey task when adding it
1809 for in silc_server_create_channel_key.
1811 * Changed the silc_server_create_channel_key to return
1812 TRUE or FALSE to indicate the success of the channel key
1815 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1817 * Fixed MSVC++ project files and added missing files to
1818 Makefiles under win32/.
1820 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * Do not add TCP_NODELAY flag if the operating system
1823 does not have it defined. Affected files are
1824 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1826 * Fixed buffer overflow from Irssi SILC Client. Affected
1827 file irssi/src/fe-common/core/themes.c.
1829 * Fixed double free in client library in the file
1830 lib/silcclient/client.c when disconnecting from server.
1832 * Applied double free patch from cras to Irssi SILC client.
1833 Affected files irssi/src/core/[modules/expandos].c
1835 * Fixed the disconnection handling to Irssi SILC Client.
1836 The application must call silc_client_close_connection
1837 in ops->connect client operation in case of failure of
1838 the connection. Affected file is
1839 irssi/src/silc/core/client_ops.c.
1841 * Do not set sock->protocol to NULL in the function
1842 silc_client_close_connection after executing the protocol's
1843 final callback since the sock might not be valid anymore.
1844 Affected file lib/silcclient/client.c.
1846 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1848 * Do not enable SILC_THREADS if the linking with libpthread
1849 did not happen. Affected file configure.in.pre.
1851 * Added notion to protocol specification that server must
1852 verify the sent authentication payload with CMODE when
1853 setting the channel founder key. Implemented it to the
1854 server. Affected file silcd/command.c.
1856 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * Added _EXTRA_DIST SILC distribution variable to the
1859 distributions file. It is used to conditionally add extra
1860 files or directories to the specific distribution. Affected
1861 files ./prepare, Makefile.am.pre and distributions.
1863 Removed the `_' from the start of the distribution names.
1866 * Added README.WIN32 for instructions to compile the Toolkit
1869 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1871 * Fixed a double free in disconnection in the server. Affected
1872 file is silcd/server.c.
1874 * Fixed the lib/silcske/groups.c to work now also with GMP
1875 MP library. The string conversion did not work when using
1876 specific base and the base is indicated in the string as well.
1878 * Created win32/ directory which now includes MSVC++ specific
1879 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1880 It will appear only in the toolkit distribution
1882 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1884 * Changed the key material distribution function in case when
1885 the hash output is too short. The data is now concatenated
1886 a bit differently than it used to. Made the change to the
1887 SKE protocol specification.
1889 * Added better GMP detection to configure.in.pre. A patch
1892 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1894 * Fixed a minor bug in SKE that might cause some problem on
1895 some platforms. Affected file lib/silcske/silcske.c.
1897 * Added the cookie checking for initiator in the SKE. It checks
1898 that the responder returns the sent cookie unmodified. The
1899 affected file is lib/silcske/silcske.c. Added new SKE
1900 error type INVALID_COOKIE that can be sent during the
1901 negotiation. Fixed some memory leaks as well.
1903 * Added the "invalid cookie" error message to Irssi SILC client's
1906 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1908 * Added `task_max' field to the SilcClientParams to indicate
1909 the maximum tasks the scheduler can handle. If set to zero,
1910 default values are used. Affected file lib/silcclient/silcapi.h.
1912 * Fixed memory leaks in silc_client_close_connection. Affected
1913 file lib/silcclient/client.c.
1915 * Added silc_client_del_client_entry to client library to free
1916 all memory of given client entry. Affected file is
1917 lib/silcclient/idlist.[ch].
1919 * Added new functions silc_client_del_channel and
1920 silc_client_del_server to delete channel and server entries.
1921 Affected file lib/silcclient/[silcapi.h/idlist.c].
1923 * Removed silc_client_del_client_by_id from silcapi.h.
1925 * Fixed the INFO command to return the server's own info
1926 correctly when querying by Server ID. Affected file is
1929 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Removed the non-blocking settings in WIN32 code in the
1932 silc_sock_[read/write] and added SleepEx instead. Affected
1933 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1934 of input data is now checked with FIONREAD and ioctlsocket.
1936 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Call silc_schedule_task_del_by_context in the
1939 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1940 Affected file lib/silccore/silcprotocol.c.
1942 * Call silc_protocol_cancel for active protocols in the
1943 silc_server_close_connection if the funtion
1944 silc_server_free_sock_user_data has not been called.
1945 Affected file silcd/server.c.
1947 * Generic tasks cannot be deleted using the del_by_fd
1948 task deleting function since generic tasks does not match
1949 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1951 * Added a notion to SILCOPER help file that the SILCOPER works
1952 only on router server, not on normal server.
1954 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * Added for WIN32 support for the new scheduler as well.
1957 Affected file lib/silcutil/win32/silcwin32schedule.c.
1959 * Fixed the SHA1 implementation to work on various platforms.
1961 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1963 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1964 API. It is part of the scheduler now. Everything else is
1965 as previously but some functions has changed their names.
1966 Checkout the lib/silcutil/silcschedule.h for the interface.
1967 Updated all applications to use the new interface. Affected
1968 files are lib/silcutil/silcschedule.[ch].
1970 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1972 * Found a bug in the SKE implementation. The HASH value,
1973 specified by the protocol, was not computed correctly. The
1974 public key of the responder was not added to the computation
1975 even though it is mandatory. Affected file lib/silcske/silcske.c.
1976 This unfortunately causes incompatibilities with older
1977 clients and servers.
1979 * Added WIN32 specific network init and uninit functions:
1980 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1981 the Winsock2. Affected file lib/silcutil/silcnet.h and
1982 lib/silcutil/win32/silcwin32net.c.
1984 * Set the socket always to nonblocking mode on WIN32 after
1985 reading data or writing data. Affected file is
1986 lib/silcutil/win32/silcwin32sockconn.c.
1988 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Fixed various compilation problems under WIN32. Affected
1991 files lib/silcutil/win32/silcwin32thread.c and
1992 lib/silcutil/win32/silcwin32schedule.c.
1994 * Removed all _internal.h #includes from public header
1995 files. Internal headers must never be included from
1998 Removed also the lib/silcske/payload_internal.h file.
2000 * All include files that may be needed (public and some others
2001 included by the public headers) by application developers are
2002 now copied to the ./includes directory. It does not copy any
2003 internal headers. Affected file Makefile.defines.pre and all
2004 Makefile.am's under lib/ and subdirs.
2006 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2008 * Do not change the ~/.silc directory's permissions automatically.
2009 Affected file irssi/src/silc/core/clientutil.c.
2011 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2013 * Do not cancel the protocol in silc_server_close_connection
2014 it might cause recursion. Now cancelled in the function
2015 silc_server_free_sock_user_data. Affected file silcd/server.c.
2017 * Fixed the silc_server_remove_clients_by_server to regenerate
2018 the channel keys correctly finally. Added also new function
2019 silc_server_remove_clients_channels to actually do it.
2020 Affected file silcd/server.c.
2022 * Fixed the silc_server_new_channel to not crash by giving
2023 wrong router to the new channel. Affected file is
2024 silcd/packet_receive.c.
2026 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2029 which is given as argument to the silc_client_alloc now.
2030 It can be used to configure the client and set various parameters
2031 that affect the function of the client.
2033 * The USERS command in server did not check whether the channel
2034 is private or secret. Affected file silcd/command.c.
2036 * Added new argument to the USERS command in protocol specification.
2037 The USERS command now can take the channel name as argument
2038 as well. Added support for this in client and server and
2039 updated the protocol specs.
2041 * Completed the GETKEY command in client. It can be now used
2042 to fetch also servers public key not only some clients.
2043 Affected files lib/silcclient/command[_reply].c.
2045 * Added silc_client_get_server to return server entry by the
2046 server name. Affected files lib/silcclient/silcapi.h and
2049 * Redefined the IDENTIFY command in protocol specification to be
2050 more generic. It now can be used to query information about
2051 any entity in the SILC Network, including clients, servers and
2052 channels. The query may be based either the entity's name
2053 or the ID. Added support for this in both client and server.
2055 Affected files silcd/command.c and lib/silcclient/command.c
2056 and command_reply.c.
2058 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2059 the _from_client and _from_server functions. Affected file
2062 * Added silc_client_get_channel_by_id_resolve to the file
2063 lib/silcclient/silcapi.h to resolve channel information by
2064 its ID. Added also silc_client_get_channel_by_id that
2065 does not resolve it from the server.
2067 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2069 * Added SilcServerEntry context into the client library
2070 to represent one server. The INFO command now allocates
2071 these to save the resolved server info. For now on the
2072 client library will also keep information about servers,
2073 connected and resolved with INFO.
2075 The INFO command now allocates the SilcServerEntry context
2076 and saves the server info there. The COMMAND_REPLY in
2077 the INFO now returns the parameters to application in
2078 same order as defined in the protocol specification.
2080 The entries are cached in the client->server_cache.
2082 * The INFO command is now issued after received the Client ID
2083 from the server. Affected file lib/silcclient/client.c.
2085 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2086 to the application as the mode changer might be server.
2087 It is guaranteed that NULL is not returned anymore to the
2088 application. Affected file lib/silcclient/client_notify.c.
2090 The ID Type is now also passed to the application so that
2091 it can check whether the returned entry is SilcClientEntry
2094 Added new function silc_client_get_server_by_id to return
2095 the server entry by ID. Affected files are the
2096 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2098 * Do not create the channel in the Irssi SILC Client when issuing
2099 the JOIN command but when received the sucessful JOIN command
2100 reply. Otherwise the channel might get created even though we
2101 could not join it. The Affected file is
2102 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2104 * Fixed a channel joining bug in router. The router must also
2105 check the channel modes, invite and ban lists etc. when serving
2106 the JOIN command sent by normal server. Affected file is
2107 silcd/command.c. The router now resolves the client's
2108 information from the server who sent the JOIN command if it
2109 does not know it, and processes the JOIN command only after
2112 * Changed the SilcCommandCb to take new argument; void *context2.
2113 Affected file lib/silccore/silccommand.h
2115 The second argument in the command callbacks in the server now
2116 includes the SilcServerCommandReplyContext if the command was
2117 called as pending command callback from the command reply.
2118 Otherwise it is NULL. When called as pending the status of the
2119 command reply will be checked and if it was erronous the
2120 error will be sent to the original sender of the command.
2121 This way the client always receives the error messages even
2122 though the server was actually the one who received the error
2123 when it resent the command to router, for example. Affected
2124 files silcd/command[_reply].[ch].
2126 * Fixed sending WHOWAS command's error message to client if
2127 the requested client could not be found. It was missing.
2130 * Changed the CMODE and CUMODE commands reply arguments in the
2131 protocol specification. The Channel ID is now sent in both
2132 of the commands to identify the channel. Implemented this
2133 new feature to the client and server. Affected files
2134 lib/silcclient/command_reply.c and silcd/command.c.
2136 * Made better checks for invite and ban lists in the JOIN
2137 command in server. Affected file silcd/command.c.
2139 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2141 * The server now performs the incoming host IP/DNS lookup
2142 using the silc_socket_host_lookup and thus does not block
2143 the server anymore. Affected file silcd/server.c.
2145 * Completed the multi-thread support for SILC Scheduler in
2146 the lib/silcutil/silcschedule.c.
2148 * Fixed the configure.in.pre to detect the pthread correctly
2151 * Fixed a deadlock in silc_task_queue_wakeup in the file
2152 lib/silcutil/silctask.c.
2154 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Added new function silc_schedule_wakeup that is used in
2157 multi-threaded environment to wakeup the main thread's
2158 schduler. It needs to be used when a thread adds a new task
2159 or removes a task from task queues. After waking up, the
2160 scheduler will detect the task queue changes. If threads
2161 support is not compiled in this function has no effect.
2162 Implemented the wakeup mechanism to both Unix and WIN32
2163 systems. Affected files are lib/silcutil/silcschedule.[ch],
2164 lib/silcutil/unix/silcunixschedule.c and the
2165 lib/silcutil/win32/silcwin32schedule.c.
2167 * Added new function silc_task_queue_wakeup to wakeup the
2168 scheduler by the specified task queue. Affected file
2169 lib/silcutil/silctask.[ch].
2171 * The silc_socket_host_lookup_start now wakes up the scheduler
2172 after adding the timeout task. Affected file is
2173 lib/silcutil/silcsockconn.c.
2175 * The silc_socket_host_lookup is synchronous now if the threads
2176 support is not compiled in. However, the callback is still
2177 called asyncronously through the scheduler, anyway. Affected
2178 file lib/silcutil/silcsockconn.c.
2180 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2182 * Added new function silc_socket_host_lookup to perform
2183 asynchronous IP and FQDN lookups for the socket connection.
2184 Affected files lib/silcutil/silcsockconn.[ch].
2186 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2189 that may or may not compile the mutex support in.
2191 Changed the silc_mutex_alloc interface. It allocates the
2192 mutex now to the sent pointer and returns TRUE or FALSE.
2194 Affected file lib/silcutil/silcmutex.h.
2196 * Wrote the SILC Task Queue interface to support multi-threads.
2197 Affected file lib/silcutil/silctask.[ch].
2199 * Wrote the SILC Scheduler to support multi-threads. Affected
2200 file lib/silcutil/silcschedule.c.
2202 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2205 in lib/silcutil/win32/.
2207 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2209 * Defined SILC Mutex API and SILC Thread API and implemented
2210 them for Unix. Affected files are
2211 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2212 lib/silcutil/unix/silcunixmutex.c and
2213 lib/silcutil/unix/silcunixthread.c.
2215 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2217 * Fixed the silc_server_remove_clients_by_server's channel
2218 key re-generation. The hash table handling was incorrect
2219 and would not work with many channels. Affected file is
2222 * Fixed some memory leaks around the server code.
2224 * Rewrote the silc_server_get_users_on_channel to support IPv6
2225 based Client ID's. Affected file silcd/server.c.
2227 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2228 specification. However, a separate document must be written
2229 to define the detailed signing procedure and the payload
2230 associated with the flag. Defined the flag to the
2231 lib/silccore/silcchannel.h as well.
2233 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2235 * Changed the dynamic tables to static size tables in the
2236 lib/silccrypt/silchmac.c.
2238 * Removed GCC dependencies from the code. A patch by cras.
2240 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Do not show the error "Error receiving packet bla bla"
2243 in server if it really was not an error (-2 means that reading
2244 is pending). Affected file silcd/server.c.
2246 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Fixed a possible crash in silc_server_remove_clients_by_server
2249 in silcd/server.c. Fixed there also some memory leaks.
2251 * Fixed the silc_idlist_replace_client_id. It could replace
2252 wrong key in the hash table. Affected file silcd/idlist.c.
2254 * Do not check whether there are global users on the channel
2255 if the channel->global_users is FALSE. Affected functions
2256 silc_server_remove_from_one_channel and
2257 silc_server_remove_from_channels in silcd/server.c. Also,
2258 do not check if the removed client is local as we can be
2259 sure that global client was not removed from the channel
2260 and checking for global users is not needed.
2262 * The silc_server_remove_clients_by_server now re-generates
2263 the channel keys correctly for those channels that had
2264 clients removed from them. Affected file silcd/server.c.
2266 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Found the reason of random crashes in the server. We weren't
2269 ignoring the SIGPIPE signal (which can be sent in write())
2270 and it crashed the server. Affected file silcd/silcd.c.
2272 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Assure that sock->user_data is not NULL in the function
2275 silc_server_packet_send in silcd/packet_send.c.
2277 * Disconnect the remote connection if it could not be added
2278 to any ID lists in the server. The affected file is
2281 * Check in silc_server_packet_send[_real/dest] that the
2282 socket is not disconnecting and ignore the data if it is.
2283 Affected file silcd/packet_send.c.
2285 * Define inline to __inline on native WIN32 compilation.
2286 Affected file includes/silcwin32.h.
2288 * Added some explicit type casts for inline code since MSVC
2289 require them. Affected files lib/silcutil/silcbuffer.h,
2290 lib/trq/silcdlist.h and lib/trq/silclist.h.
2292 * Print warning in log files from now on if the packet
2293 decryption fails. Affected file silcd/server.c.
2295 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2297 * Changed the `say' client operation's interface to accept
2298 new `type' argument to indicate the type of the message sent
2299 by the library. The application may filter the library's
2300 messages according the type. The affected file is the
2301 lib/silcclient/silcapi.h.
2303 * Added two new functions to lib/silcclient/silcapi.h:
2304 silc_client_del_client and silc_client_del_client_by_id.
2305 Affected file lib/silcclient/idlist.c.
2307 * Moved the clientincludes.h from includes/ to silc/ and
2308 serverincludes.h from includes/ to silcd/.
2310 * The modes for the CMODE and CUMODE are now passed as
2311 uint32 for application with COMMAND_REPLY. The affected
2312 file is lib/silcclient/command_reply.c.
2314 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2316 * /WHOIS without arguments shows client's own information.
2317 Affected file lib/silcclient/command.c.
2319 * Changed PING to not accept any arguments. The specs
2320 says that client can ping only the connected server so
2321 requiring an argument is not needed. Affected file is
2322 lib/silcclient/command.c.
2324 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Fixed a fatal bug in private message sending and reception
2327 encryption and decryption when using private message keys.
2328 The implementation was incorrect and did not follow the
2329 specification. It causd that some of the message were
2330 lost since it did not use the sending and receiving keys
2331 as the protocol suggests. This has been fixed and will cause
2332 incompatibilities with older clients when sending private
2333 message encrypted with private message keys. Affected files
2334 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2335 and various other in Irssi SILC Client.
2337 Added `responder' boolean argument to the functions
2338 silc_client_add_private_message_key[_ske] to indicate when
2339 the key is added as responder or initiator of the key
2342 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Removed the silc_ske_check_version function and created
2345 a SilcSKECheckVersion callback. Added also a function
2346 silc_ske_set_callbacks that is now used to set all SKE
2347 callbacks. The callback functions are not given to
2348 the SKE functions anymore, but this function is used to
2351 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2353 * Added `silc_version' argument to the silc_client_alloc
2354 to define the version of the application for the library.
2355 The library will use the version string to compare it
2356 against the remote host's (usually a server) version
2357 string. Affected file lib/silcclient/silcapi.h
2359 * Added the KE protocol context to Key Agreement context
2360 in client library so that we can abort the SKE if it
2361 is in process when we get timeout. Affected file is
2362 lib/silcclient/client_keyagr.c.
2364 * Do not resolve the client ID forever if it returns in the
2365 first time that such client does not exist. This was done
2366 for example with private message. Affected file is
2367 lib/silcclient/client_prvmsg.c.
2369 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * Do not add regex.h for WIN32. The affected file
2372 includes/silcincludes.h.
2374 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2375 not work yet 100%. It generates the DLL's automatically
2376 when compiling with --with-win32 under cygwin.
2378 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2380 * lib/contrib/regex.c is not compiled on WIN32.
2382 * Added silc_net_get_socket_opt function to the
2383 lib/silcutil/silcnet.h.
2385 * Added includes/silcwin32.h for WIN32 specific includes
2388 * Do not use ptime structure or any of the posix process
2389 functions on WIN32 in lib/silccrypt/silrng.c.
2391 * Added silc_gettimeofday to provide generic function
2392 for struct timeval on all platforms. Added the function
2393 to lib/silcutil/silcutil.h.
2395 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2397 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2398 library as they clearly belong there. As a plus side we
2399 can make the actual socket connection routines platform
2402 Added also new generic function silc_socket_read and
2403 silc_socket_write (that used to be silc_packet_[read/write].
2404 The implementation of these are platform specific.
2406 * Added WIN32 specific routines of silc_socket_[read/write]
2407 to lib/silcutil/win32/silcwin32sockconn.c.
2409 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Added preliminary support for native WIN32 compilation under
2412 cygwin (using the -mno-cygwin option for GCC) to the
2413 ./configure.in.pre. The --with-win32 now prepares the
2414 compilation for native WIN32.
2416 * Rewrote the SILC Scheduler interface in the file
2417 lib/silcutil/silcschedule.h. The scheduler is now context
2418 based and does not have anymore any global static scheduler.
2419 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2420 and created lib/silcutil/win32 directory for WIN32 based
2423 * Added Unix specific network routines to the
2424 lib/silcutil/unix/silcunixnet.c and the old
2425 lib/silcutil/silcnet.c includes now only generic routines.
2427 Added WIN32 specific network routines to the
2428 lib/silcutil/win32/silcwin32net.c.
2430 * Added Unix specific utility functions from the
2431 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2433 * Added WIN32 SILC Scheduler to the file
2434 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2437 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2439 * Do not handle JOIN notify in the server if the target client
2440 is not registered (idata->registered == FALSE). The affected
2441 file is silcd/packet_receive.c.
2443 * Update the nickrec->founder in event_cumode in the Irssi SILC
2444 client. Affected file irssi/src/silc/core/silc-channels.c.
2446 * Fixed the CUMODE_CHANGE notify handling in the server when
2447 server and router are announcing their clients on channels.
2448 Now the mode changes are saved and notified correctly. The
2449 affected file is /silcd/packet_receive.c.
2451 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2452 They really did not replace the cache entry in the ID Cache.
2453 Now they do that. Affected file silcd/idlist.c.
2455 * Fixed the KICK notify handling in the Irssi SILC client to
2456 update the channel records so that the kicked client does not
2457 appear to be on the channel. The affected file is
2458 irssi/src/silc/core/silc-channels.c.
2460 * Always update the conn->current_channel when executing command
2461 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2463 * Fixed the KILL notify handling in Irssi SILC client to remove
2464 the killed client on all channels.
2466 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Fixed the silc_parse_command_line to remove extra spaces
2469 from the start and end of the arguments. Affected file is
2470 lib/silcutil/silcutil.c.
2472 * Cancel and free any active protocol in the function
2473 silc_server_close_connection. Affected file silcd/server.c.
2475 * Cancel and free any active protocol in the function
2476 silc_client_close_connction. Affected file is
2477 lib/silcclient/client.c.
2479 * Do not execute the KILL command for clients that are in
2480 history (ie. they are not in the network). Affected file is
2483 * Fixed KILL notify handling, client does not crash anymore.
2484 Affected file irssi/src/silc/core/silc-channels.c.
2486 * Reduced the default packet buffer size from 2048 to 1024 in
2487 lib/silccore/silcpacket.c.
2489 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2490 counter to the SKE context that is incresed when the SKE library
2491 performs async operation outside the library. If the outside
2492 process frees the SKE context and FREED status will be set
2493 and the library will detect after the sync operation that the
2494 libary is freed. The affected files are
2495 lib/silcske/silcske[_status].[ch].
2497 * Resolve the client entry information in the function
2498 silc_client_channel_message to assure that NULL pointer is not
2499 passed as client entry to the application. */
2501 * Fixed the task timeout calculation to assure that there is
2502 never negative timeouts. The affected file is
2503 lib/silcutil/silcschedule.c.
2505 * Fixed the channel user mode notification sending in server.
2506 It was sent point-to-point to the router (or to server by router)
2507 but it needs to be destined to a channel. The routines now
2508 supports sending the channel user mode notifys to the channels
2509 when announcing clients and channels. Affected files are
2510 silcd/server.c and silcd/packet_receive.c.
2512 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2513 It did not actually replace the old channel entry in the cache.
2514 Affected file lib/silcclient/client_notify.c.
2516 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2518 * Fixed a possible crash in silc_packet_send_prepare. It now
2519 assures always that there is enough space in the buffer and
2520 at the tail area of the buffer (for MAC).
2522 Fixed the inbound buffer reallocation in silc_packet_read.
2523 It was old code and did not handle the reallocation correctly.
2526 The affected file is lib/silccore/silcpacket.c.
2528 * Fixed buffer overflow in silc_parse_nickname in the file
2529 lib/silcutil/silcutil.c.
2531 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2533 * make install generates new server keys only if there is not
2536 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2539 Added check that if the NOREPLY is set then we will not send
2540 the away message. This avoids infinite loop of away messages
2541 if both clients are away. The affected file is
2542 lib/silcclient/client_prvmsg.c.
2544 * Fixed client crash if /NICK was given without arguments.
2545 Affected file lib/silcclient/command.c.
2547 * Server does not send the invite list in INVITE command back
2548 to the client if the list was not altered. Added this notion
2549 to the protocol spec as well. Affected file silcd/command.c.
2551 Fixed possible crash in INVITE command by checking the
2552 value of silc_server_get_client_route command.
2554 * Fixed the INVITE notify type handling. The arguments are now
2555 taken in correct order and client does not crash. The affected
2556 file is irssi/src/silc/core/silc-channels.c.
2558 Removed the "Inviting xxx to channel" message from the
2559 client library away and let the application handle it.
2560 Affected file lib/silcclient/command.c. Added that message
2561 to Irssi SILC client's message formats.
2563 * Fixed CMODE command crash in client. It now checks the
2564 amount of arguments correctly and does not crash. The affected
2565 file is lib/silcclient/command.c.
2567 * Do not create new channel automatically in silc_channels_join
2568 but check whether the channel by that name already exists.
2569 Affected file irssi/silc/core/silc-channels.c.
2571 * Do not send the SERVER_SIGNOFF to router if the disconnected
2572 entity was the router. Affected file silcd/server.c.
2574 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2575 SILC client as it was missing from there.
2577 Added the handling of the KICK notify to the Irssi SILC client
2578 as it was missing. Added "you have been kicked" message to
2579 Irssi SILC client's message modules formats.
2581 Added the handing of the KILL notify to the Irssi SILC client
2582 as it was missing. Added the kill message module formats
2585 The affected file is irssi/src/silc/core/silc-channels.c.
2587 * The router did not save the channel mode the server announced.
2588 Affected file silcd/packet_receive.c.
2590 * Fixed a possible crash in INFO command in server. If the
2591 server did not provide the server info it crashed. Affected
2592 file silcd/command.c.
2594 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Fixed the GETKEY command in the server to check also the
2597 global list. Otherwise the GETKEY would not work correctly
2598 in normal SILC server. Affected file silcd/command.c.
2600 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * Fixed GETKEY crash, it crashed if the command did not succseed.
2604 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2607 is now real and not just an macro interface to GMP.
2609 Removed the entire GMP from the source tree and imported new
2610 NSS MPI library instead. Reason for removing GMP is that it is
2611 extremely large and compiles extremely slow. The NSS MPI
2612 is only a few files and compiles in less than 10 seconds.
2613 The speed is also about the same as GMP. The MPI is imported
2614 to lib/silcmath/mpi.
2616 If the system has GMP installed we will still use the GMP.
2617 If it is not then the NSS MPI will be compiled.
2619 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2621 * Merged a long nickname (127 characters long) crash bugfix from
2622 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2624 * Merged a freed memory reference bugfix from Irssi CVS tree.
2625 Affected file irssi/src/core/commands.c.
2627 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Added the server's public key sving and verification to the
2630 server when performing the SKE. This was missing and the
2631 remote server's (or router's) public key was accepted without
2632 checking whether we have it previously or trust it at all.
2633 Affected file silcd/protocol.c.
2635 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Check in the silc_server_timeout_remote if protocol is active
2638 and make sure that the protocol's final callback is called so
2639 that all memory if freed. Affected file silcd/server.c.
2641 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * silc_server_whois_send_reply crashed the server if the nickname
2644 was 127 characters long. Affected file silcd/command.c.
2646 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Added sanity check to the silc_server_new_client. If the hostname
2649 is provided inside username then check that the provided hostname
2650 really is the same as the resolved one. If the hostname was not
2651 resolved then check it from the public key. Affected file is
2652 silcd/packet_receive.c.
2654 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2655 if the server disconnected us and the connection is not valid
2656 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2658 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2659 the library to the lib/silcutil/silcutil.[ch].
2661 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * Close log file after open. Affected file
2664 lib/silcutil/silclog.c.
2666 * Check whether sock == NULL in silc_client_send_packet and return
2667 if it is. Affected file lib/silcclient/silcclient.c.
2669 * Check rec->entry == NULL in the Irssi SILC Client before
2670 sending the channel message. Affecte file is
2671 irssi/src/silc/core/silc-servers.c.
2673 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2675 * Merged a splitted window bugfix from Irssi CVS tree. The
2676 affected file is irssi/src/fe-text/textbuffer-view.c.
2678 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2679 It did not print nickname.
2681 * Improved the distributions system a bit.
2683 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2686 irssi/src/fe-text/gui-window.c.
2688 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2689 to in-active server. The affected file is
2690 irssi/src/silc/core/client_ops.c.
2692 * Resolve the client in USERS command reply if the entry does
2693 not have username resolved. The affected file is
2694 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2695 command to WHOIS command to really resolve stuff. The USERS
2696 is not used any more in any critical section so WHOIS can
2697 be used even though it might be slower than IDENTIFY.
2699 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2702 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2704 * Changed the protocol API a bit more consistent in the
2705 lib/silccore/silcprotocol.[ch].
2707 * Changed the following headers to ROBODoc format:
2709 lib/silccore/silcpayload.h
2710 lib/silccore/silcprotocol.h
2711 lib/silccore/silcsockconn.h
2713 All core library headers are now formatted.
2715 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2717 * Fixed a bug in Irssi SILC client; do not show that you are
2718 server/router operator if you really are not. Affected file is
2719 irssi/src/silc/core/client_ops.c.
2721 * Renamed silc_command_free_payload to silc_command_payload_free.
2722 Affected file lib/silccore/silccommand.h
2724 * Added silcmath.h to include the prototoypes of various routines
2725 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2728 * Changed the following headers to ROBODoc format:
2730 lib/silccore/silcchannel.h
2731 lib/silccore/silccommand.h
2732 lib/silccore/silcid.h
2733 lib/silccore/silcidcache.h
2734 lib/silccore/silcmode.h
2735 lib/silccore/silcnotify.h
2736 lib/silccore/silcpacket.h
2737 lib/silcmath/silcmath.h
2739 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Added checking to the server code not to start the server if
2742 ciphers and stuff are not configured properly. Affected files
2743 silcd/serverconfig.[h] and silcd/server.c.
2745 * Changed the layout of the header files of the public interfaces
2746 in the SILC libraries. The new layout supports ROBODoc
2747 documentation tool (and some others) so that it is easy to create
2748 a library reference manual. All the other headers and source
2749 code must still follow the CodingStyle document. Also source
2750 code must not include these ROBODoc stuffs, only the headers.
2751 Furthermore, all public interface headers must now be named
2752 by using `silc' prefix, example: silcapi.h, silccipher.h.
2753 Some files were renamed due to this. All the other headers
2754 must not be used as public interfaces. I will update the
2755 CodingStyle document later. Changed following headers, so far:
2757 lib/silcclient/silcapi.h
2758 lib/silccore/silcauth.h
2759 lib/silccore/silcprivate.h
2760 lib/silccrypt/silcdh.h
2762 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Removed silc_client_packet_send_flush from the client library
2767 as it is not needed. Affected file lib/silcclient/client.[ch].
2769 * Added printing of message of unresolved authentication method
2770 to the Irssi SILC client. Added it to the module formats.
2771 Removed the same message from the client library.
2773 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2775 * Added new distribution feature, DISTLABEL. Every distribution
2776 can define own preprocessor label that can be used in the
2777 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2778 file distributions, acconfig.h.pre and prepare.
2780 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2782 * Added Makefile.defines_int to include the actual definitions
2783 for Makefile.defines.in. Tested the new distribution system,
2784 created distributions and tested installation.
2786 * Added AWAY message printing to the Irssi SILC client. Added
2787 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2789 * Added SCONNECT command to call the SILC's CONNECT command.
2790 Cannot use CONNECT directly since Irssi uses that internally.
2791 Affected file irssi/src/silc/core/silc-servers.c.
2793 Added ACTION local command. It is same as ME command but takes
2794 the channel as mandatory argument.
2796 Rewrote some of the Irssi's help files to suite for SILC
2799 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Added Makefile.defines[.in] that should for now on be included
2802 in all Makefile.am file in the source tree. That file includes
2803 all common compilation definitions for SILC source tree.
2805 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2807 * Minor changes to the ./prepare script to change the package
2808 name according the distribution name to the configure.in.
2810 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2812 * Created new distribution system. Added file `distributions'
2813 that defines all the distributions that can be created out of
2814 the SILC source tree. The ./prepare script now reads that
2815 file to determine how to prepare the distributions. The
2816 first argument to the ./prepare is the name of the distribution
2817 and second is the version of the distribution. If given
2818 without arguments it creates the default (toolkit) distribution
2819 with the default version (defined in ./prepare).
2821 All Makefile.am files that are subject to the distributions
2822 are now named as Makefile.am.pre. These are ./Makefile.am
2823 and lib/Makefile.am. Others may be changed later.
2825 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2827 * Added invite list, ban list, some key management and connection
2828 error message printing to module formats in the Irssi SILC client.
2830 * Added new silc_client_set_away_message to set the away message
2831 that is back to the person who sent private message. The
2832 affected file lib/silcclient/silcapi.h and the
2833 lib/silcclient/client_prvmsg.c.
2835 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2837 * Fixed the private message sending in the Irssi SILC client,
2838 added local command KEY to the Irssi SILC client.
2840 Added key management and key agreement message formats to the
2841 irssi/src/fe-common/silc/module-formats.[ch].
2843 Added USERS (alias WHO) printing, server/router operator
2844 indication and LIST command printing to the module formats.
2846 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Fixed channel joining notify handling, cumode notify handling
2849 from Irssi SILC client.
2851 * Added SILC specific module-formats to the Irssi SILC client so
2852 that SILC specific message hilighting, colors etc is possible.
2853 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2855 Added channel mode, channel user mode, actions, notices,
2856 whois and whowas printing to the the module-formats.c.
2858 * Fixed a bug in channel deletion in the server. The channel
2859 is not left to the cache even if the channel founder auth mode
2860 is set when there are no users anymore on the channel. Affected
2861 file silcd/server.c.
2863 * The silc_net_localhost now resolves the entire hostname including
2864 the domain name. Affected file lib/silcutil/silcnet.c.
2866 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Changed the ask_passphrase client operation to be ascynchronous.
2869 It has now a completion callback and a context that the
2870 application must call after it has got the passphrase from
2871 the user. Affected files lib/silcclient/silcapi.h,
2872 lib/silcclient/protocol.c, lib/silcclient/command.c and
2875 Added SilcAskPassphrase callback that the application calls
2876 to deliver the passphrase to the library.
2878 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2879 The public key verification and especially a certificate
2880 verification is asynchronous procedure.
2882 Added new SILC_SKE_STATUS_PENDING status to indicate the
2883 request is pending and a callback will be called to finalize
2886 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2887 indicate that remote end did not send its public key (or
2888 certificate), even though we require it. Added check for this
2889 condition in the SKE. This was a security bug, now fixed.
2891 Defined new SilcSKEVerifyCbCompletion callback that is called
2892 when the verification process is completed.
2894 The affected files lib/silcske/silcske_status.h and
2895 lib/silcske/silcske.[ch].
2897 * Changed the verify_public_key client operation to be async
2898 as well. Defined SilcVerifyPublicKey callback that is used to
2899 indicate the success of the public key verification process.
2901 Changed the server and client to use the new async client
2904 * Changed the Irssi SILC client's internal scheduler to be called
2905 twice as many times as it used to be. As a result the client
2906 should be a bit faster now. Affected file is
2907 irssi/src/silc/core/silc-core.c.
2909 * Added support to Irssi SILC client of asynchronous public key
2910 verification and passphrase inquiry. Affected file is
2911 irssi/src/silc/core/silc-core.c.
2913 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2915 * Do not say "You have left channel %s" in client library.
2916 Moved it to the application. Affected files are
2917 lib/silcclient/command.c and silc/client_ops.c.
2919 * Fixed silc_client_get_clients. Command context was not
2920 duplicated and was freed memory in the callback. Affected
2921 file lib/silcclient/idlist.c.
2923 * Do not say "you are now talking..." on JOIN command in the
2924 client library. The appliation must handle it.
2926 * Do not say ".. changed topic to" in command reply in the
2927 client libary. The application must handle it.
2929 * Fixed TOPIC command sending in the client library.
2931 * Fixed a memory leak in silc_client_command_free in the file
2932 lib/silcclient/command.c.
2934 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Imported a modified version of Irssi client to the source tree.
2937 The Irssi will be used to create a new client called
2938 Irssi SILC. Imported to irssi/.
2940 Added silc_core_init_finish function to the Irssi. Affected
2941 file irssi/configure.in.
2943 A lot changes in the Makefile.ams around the irssi tree.
2945 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * Do not rehash if the new size is same as the old size of the
2948 hash table, in the silc_hash_table_rehash*. The affected file
2949 lib/silcutil/silchashtable.c.
2951 * Replaced hash_table_del_by_context calls from the server
2952 (when channel->user_list and client->channels) to the
2953 hash_table_del as it is sufficient and faster.
2955 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Added silc_hash_table_list, silc_hash_table_get and the
2958 SilcHashTableList structure to provide an alternative way to
2959 traverse the hash table. The affected files are
2960 lib/silcutil/silchashtable.[ch].
2962 * Changed the server's idlist routines to use the hash table
2963 routines to optimize the code.
2965 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Replaced the client entry's `channel' list and channel entry's
2968 `user_list' list to hash tables for optimized lookup. Changed
2969 the code to use the hash table interface around the code.
2970 Affected file lib/silcd/idlist.[ch].
2972 * Added `auto_rehash' boolean argument to the function
2973 silc_hash_table_alloc to indicate whether the hash table should
2974 auto-rehash when it thinks is appropriate time. It will
2975 increase the hash table size if the there is twice as much
2976 entries in the table than the size of the table, and will
2977 decrease the size if there are twice as less entries than
2978 the size of the table.
2980 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2984 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2986 * silc_idcache_purge_by_context deletes the entry now by context
2987 as it is supposed to do. Affected file lib/silccore/idcache.c.
2989 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2990 client is not anymore valid (WHOWAS givens the info) and not
2991 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2993 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Removed the `data' and `data_len' arguments from the ID Cache
2996 interfaces and added `name' argument. ID Cache does not handle
2997 anymore the binary data only a names associated with given ID.
2999 * When hashing a Client ID with silc_hash_id the entire ID is
3000 not hashed anymore, instead only the hash of the Client ID is
3001 hashed. This way we can access the Client ID from the cache
3002 with Client ID but with the hash of the ID (which is a hash of
3003 the nickname) as well without any difference in performance.
3005 Added also silc_idcache_find_by_id_one_ext to do one on one
3006 searching when we have the actual ID. Added also function
3007 silc_hash_client_id_compare. The affected files are
3008 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3010 * When hashing the name associated with a ID it is always done
3011 in lowercase. This way we can access the cache without worrying
3012 about case-sensitivity, even though, for example nicknames are
3015 * Fixed a bug in server with channel message sending. It put
3016 wrong ID type as destination ID. The affected file
3017 silcd/packet_send.c.
3019 * silc_idcache_del_by_context now deletes from all hash tables
3020 by context. Affected file lib/silccore/idcache.c.
3022 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Changed the client library to use the new ID Cache interface.
3025 Changes around the source tree.
3027 * Added silc_hash_table_rehash_ext to rehash with specific
3028 hash function. Affected file lib/silcutil/silchashtable.[ch].
3030 * Added silc_hash_string_compare to compare two strings in the
3031 hash table. Affected file lib/silcutil/silcutil.[ch].
3033 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Added new function silc_idcache_del_by_context into the
3036 lib/silccore/idcache.[ch].
3038 * Changed the server's ID list routines to use the new ID Cache
3039 interface. Changes around the source tree.
3041 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3043 * Added silc_hash_table_del[_by_context]_ext functions in to the
3044 lib/silcutil/silchashtable.[ch].
3046 Removed silc_hash_table_find_all* routines and added new
3047 silc_hash_table_find_foreach to replace them.
3049 Added silc_hash_table_replace_ext function as extended
3050 replacing function. Separated the simple hash table interface
3051 from the extended hash table interface in the file
3052 lib/silcutil/silchashtable.h.
3054 * Fixed minor bugs and changed it to use some of the new
3055 hash table functions in lib/silccore/idcache.c
3057 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3059 * Added new function silc_hash_table_find_all to return all keys
3060 in the hash table by the specified key. As the hash table is
3061 collision resistant it also makes it possible to have several
3062 duplicate keys in the hash table. This function may be used to
3063 find all of the keys from the hash.
3065 Added user_context arguments to the SilcHashFunction,
3066 SilcHashCompare and SilcHashDestructor to deliver user specified
3069 Added new fuctions silc_hash_table_find[_all]_ext to do
3070 extended lookup with specified hash and compare functions and
3071 specified user contexts.
3073 Added new function silc_hash_table_add_ext to add the key
3074 with specified hash function and user context.
3076 Added new function silc_hash_table_foreach to traverse all
3077 entrys in the hash table. Added SilcHashForeach callback
3080 Added new function silc_hash_table_del_by_context to delete
3081 the entry only if the context associated with the key matches.
3083 Affected files are lib/silcutil/silchashtable.[ch].
3085 * Removed silc_hash_[server/client/channel]_id and added just
3086 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3087 silc_hash_id_compare to compare two ID's using as the hash table
3088 comparison function. Added also silc_hash_data to hash
3089 binary data and silc_hash_data_compare to compare it.
3091 * Removed silc_idlist_find_client_by_hash as it is not needed
3092 anymore. Affected file silcd/idlist.[ch].
3094 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3095 to use internally the SilcHashTable. The new ID Cache is a lot
3096 faster than the old one. Some of the ID Cache interface was also
3097 rewritten and obsolete and stupid functions were removed.
3099 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3101 * Added entry_count field to the SilcHashTable to keep the number
3102 of the entries in the table. Implemented the function
3103 silc_hash_table_rehash. Added new function
3104 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3106 Fixed a minor bug in silc_hash_table_free.
3108 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3109 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3110 into the lib/silcutil/silcutil.[ch].
3112 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Implemented a collision resistant hash table into the
3115 lib/silcutil/silchashtable[ch]. See the header and the source
3116 for the SilcHashTable API.
3118 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Merged dotconf version 1.0.2 into lib/dotconf.
3122 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Do not compile anything in lib/silcsim/* if the SIM support
3125 is not enabled. The tree should now compile without problems
3128 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3130 * Compiled the SILC under cygwin. Compiled and tested briefly
3131 without problems. More tests needed. The SIMs didn't compile
3134 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3136 * Fixed possible crash in silc_get_username in the
3137 lib/silcutil/silcutil.c.
3139 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3141 * Fixed a va_arg in silc/client_ops.c.
3143 * Oops, RC5 routines were named AES and caused some problems
3144 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3146 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * Added new SilcIDIP structure into the lib/silccore/id.h and
3149 replaced the old `ip' fields from all SILC ID's to that type.
3150 This is a step towards IPv6 support.
3152 The silc_id_get_len takes now the ID as an extra argument.
3153 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3154 both IPv4 and IPv6 based ID's.
3156 The affected files are lib/silccore/id.[ch] and other files
3157 around the tree using these routines.
3159 * Removed the ID length arguments in server from various
3160 silc_server_send_notify_* routines -> they are not needed
3163 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3165 * Fixed memory leak in silc_encode_pem_file in the file
3166 lib/silcutil/silcutil.c.
3168 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3170 * Check minor version as well in the SKE. Affected files are
3171 silcd/protocol.c and lib/silcclient/protocol.c.
3173 * Added --identifier option to the server so that an identifier
3174 can be when creating the public key for the server. Affected
3175 file is silcd/silcd.c.
3177 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3178 lib/silccrypt/silcpkcs.c.
3180 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Register default ciphers and stuff when using -C option with
3183 the server. Affected file sildc/silcd.c.
3185 * Put back the servers public key filename format, it is better
3186 than the new one. For now, the client keys are saved with the
3187 new filename format. The affected file silc/client_ops.c.
3189 * Implemented the Cipher API for the rest of the ciphers that
3190 did not implement it or implemented it the wrong way.
3192 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Register default ciphers and stuff when using the -S option
3195 in the client. Affected file silc/silc.c. Same also when
3196 creating new key pair with -C option.
3198 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Fixed the silc_verify_public_key client operation function to
3201 save the public keys differently. The fingerprint is now
3202 used as filename and not the hostname. This way also the
3203 client keys are saved uniquely and not with hostnames. The
3204 affected file is silc/client_ops.c.
3206 * Trimmed the silc_hash_fingerprint function to remove extra
3207 whitespaces from the end of the fingerprint. The affected
3208 file is lib/silccrypt/silchash.c.
3212 * Added silc_cipher_register_default function to register all
3213 default ciphers. It can be used when configuration files
3214 does not exist and the application does not want any specific
3215 ciphers in any specific order.
3217 The SilcDList is now used as silc_cipher_list dynamically
3218 allocated cipher list. Removed the static list all together
3219 and now all ciphers must be allocated to the dynamic list.
3220 The silc_cipher_alloc routine was changed to check only the
3223 All silc_cipher_* routines that used to return int returns
3226 The affected files lib/silccrypt/silccrypt.[ch].
3228 * The same thing was done to silc_hash_* as for silc_cipher_*
3229 routines. Affected files lib/silccrypt/silchash.[ch].
3231 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3232 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3233 Added also silc_pkcs_[un]register[_default] functions.
3234 Removed the data_context from the PKCS API.
3236 * Added silc_hmac_register_default function to register default
3237 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3238 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3239 to unregister all hmacs at once.
3241 * Register the default ciphers, hash functions, PKCSs and HMACs
3242 if client's configuration file does not exist. The affected
3245 * The client did not load the hash functions from the SIM
3246 modules at all. Added support for this. Affected file is
3247 silc/clientconfig.c.
3249 * When decoding public key with silc_pkcs_public_key_decode, check
3250 the supported algorithm only if PKCS are registered. Affected
3251 file lib/silccrypt/silcpkcs.c. The same was done with the
3252 silc_pkcs_private_key_decode.
3254 * Fixed the SILC List routines to keep the list always in order.
3255 It used to change the list's order when traversing the list but
3256 not it preserves the order. Affected file lib/trq/silclist.h.
3258 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Added the client library to use the SilcSocketConnection's
3261 reference counter (by silc_socket_dup) to prevent the bug that
3262 the socket object may be freed underneath async operation.
3264 * The name resolv library checking fixes in the configure.in.pre.
3267 * Created new version of the protocol drafts for future
3268 development. The -03 drafts are the ones that will be changed
3269 in the trunk now and the -02 will remain as they are.
3271 * Send list of CUMODE notifys to the router when announcing
3272 the channel users to the router. Affected file silcd/server.c.
3273 If the router receiving channel founder CUMODE for a channel
3274 that already has channel founder it will send CUMODE notify
3275 to the sender to remove the channel founder rights from the
3276 announced client. Affected file silcd/packet_receive.c.
3278 * The CUMODE notify may now use Server ID as well as the entity
3279 who changes the mode. Updated protocool specs.
3281 * Updated INSTALL and README files.
3283 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * New web pages in the http://silc.pspt.fi. The pages was
3290 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Implemented the [DenyConnectin] config section in the server.
3293 Added silc_server_config_denied_conn to check whether incoming
3294 connection is denied. Affected file silcd/serverconfig.[ch].
3296 * Do not check the ports when checking the incoming configuration
3297 data if the port is 0, meaning any. Affected file is
3298 silcd/serverconfig.c.
3300 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Fixed buffer overflow in silc_string_compare in the file
3303 lib/silcutil/silcutil.c.
3305 * Fixed double free in silc_server_command_leave in the file
3308 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Fixed the version checking in the server. Affected file is
3313 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * Fixed the configuration data fetching when accepting new
3316 connections in the server. Affected file silcd/server.c.
3318 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Added `sender_entry' argument to the function
3321 silc_server_packet_relay_to_channel so that we can check
3322 whether some destination actually belongs to the same route
3323 the sender belongs (ie, we must not resend the packet to the
3324 sender). Affected file silcd/packet_send.[ch].
3326 * Added `servername' field to the SilcClientEntry in the server
3327 to hold the name of the server where client is from. Affected
3328 file is silcd/idlist.h.
3330 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Moved the channel message encrypting in the router betwen
3333 router connections from silc_server_channel_message to the
3334 silc_server_packet_relay_to_channel since we want to check
3335 whether we have anybody channel before encrypting anything.
3336 Affected files silcd/packet_[receive/send].c.
3338 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Fixed the [AdminConnection] server config section to support
3341 multiple entries. Affected file silcd/serverconfig.c.
3343 * Added support into the server to check the validity of the
3344 incoming connection before executing any KE or authentication
3347 * The connection configuration is now saved to the KE and
3348 connection auth protocol contexts and not fetched anymore in
3349 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3351 * The local hosts listenning address and port is also resolved
3352 now when starting the server. We want to have the socket object
3353 to include the real address and port for the listener. Added
3354 new function silc_net_check_local_by_sock into the files
3355 lib/silcutil/silcnet.[ch].
3357 * Fixed a broadcast bug in server -> do not broadcast if we
3360 * Fixed a routing bug. Do not route broadcast packets ever.
3361 Broadcast packets must be processed always and not routed since
3362 they may be destined to some other host than yourself and thus
3363 would get routed without no good reason. Affected file is
3366 * Added function silc_server_config_is_primary_route to check
3367 whether primary router connection has been configured (a router
3368 configuration that we are initiating). If there is not, we
3369 will assume that there is only two routers in the SILC network
3370 and we will use the incoming router connection as our primary
3371 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3373 * Changed the order of the broadcasting. Broadcast _after_ the
3374 packet has been processed not before. Affected file is
3377 * Fixed a [ClientConnection] parsing bug. The port was never
3378 parsed correctly thus resulting to port 0. Affected file
3379 silcd/serverconfig.c.
3381 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3382 argument and did not set the broadcast packet flag. Affected
3383 file silcd/packet_send.c. Fixed same bug in the function
3384 silc_server_send_notify as well.
3386 * If we receive NEW_ID packet for our own ID in the server, ignore
3389 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Removed the nickname from the Private Message Payload.
3394 Updated the code and the protocol specs.
3396 * Updated protocol specs for submitting to the IETF.
3398 * Tweaked the Random Number Generator a bit. Affected file
3399 lib/silccrypt/silcrng.c. Exported a new function
3400 silc_rng_[global]_add_noise which can be used to add more
3403 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Do not parse packets with different timeout when protocol
3406 is active -> may cause problem with rekey. Affected file
3409 * When server receives signoff notify it must not create
3410 new channel key if the client is on any channels since the
3411 sender of the signoff notify will create it.
3413 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Added printing of error messages during SKE protocol from the
3416 failure packet sent by server during SKE. Affected file
3419 * Removed the client's failure_callback handling with timeout
3420 and handle it immediately when received.
3422 * The SKE library returned wrong type in SUCCESS and FAILURE
3423 packets. They must be 32 bit MSB not 16 bit MSB.
3425 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Ok, rewrote the logic of the re-key and now it seems to work.
3428 I tested it on high traffic with frequent re-keys without
3429 problems. Added hmac_receive (and renamed hmac to hmac_send)
3430 in SilcClientConnection in lib/silcclient/client.h and
3431 in SilcIDListData in silcd/idlist.h. Also, removed the
3432 SilcPacketParserContext's cipher and hmac fields as they are
3433 not needed anymore and actually caused some problems when
3434 the ciphers and hmac's changed underneath the packet parser.
3436 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * If re-key protocol is active then process the incoming packets
3439 synchronously since we must assure that icoming packets encrypted
3440 with the old key is processed before the new keys is set to
3441 use. This is true other packets than for REKEY packets.
3442 Affected file silcd/server.c. The same was done to client library
3443 as well, affected file lib/silcclient/client.c.
3445 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Fixed bug in client and server to accept the force send if
3448 the packet is send from silc_[server/client]_packet_process
3449 function. Otherwise the packets are never delivered, oops.
3451 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * Disable force sending of packets when REKEY protocol is active.
3454 We must assure that no packet is sent directly when rekey is
3455 performed. All packets must be sent through packet queue.
3456 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3457 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3458 function is silc_[server/client]_packet_send_real to check
3461 * Replaced the SIM paths from example config files to
3462 /usr/local/modules. Also, make install creates now
3463 /usr/local/silc/logs directory to hold all the SILC server
3466 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3468 * Made the configure.in.pre work on Solaris. Patch by salo.
3470 * Made all ciphers compatible with non-x86 machines. Defined
3471 CBC mode macros into lib/silccrypt/ciphers_def.h.
3473 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * Fixed the make install.
3477 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * When MAC computation fails the silc_packet_decrypt returned 0
3480 even though it was supposed to return -1. Fixed this. The
3481 affected file is lib/silccore/silcpacket.c.
3483 * Do not replace the config files in /etc/silc (in make install)
3484 if they already exist. Affected file ./Makefile.am.
3486 * Do not send re-key packets immediately but through packet queue.
3487 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3489 * Changed silc_net_check_host_by_sock to return FALSE if the
3490 IP/DNS could not be resolved. Though, it returns the IP address
3491 now even if it could not resolve it (but returns also FALSE).
3492 Affected file lib/silcutil/silcnet.[ch].
3494 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * Added silc_pkcs_decode_identifier to decode the public key's
3497 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3498 Added also silc_pkcs_free_identifier. Added also new context
3499 SilcPublicKeyIdentifier.
3501 * Added -S option to the silc client. It is used to dump the
3502 contents of the specified public key file.
3504 * Changed the PKCS api to return the public key length when
3505 setting the public key.
3507 * Fixed a fatal bug in the public and private key file loading.
3508 Affected file lib/silccrypt/silcpkcs.c.
3510 * Execute the packet parsing for client with zero (0) timeout
3511 if the protocol is active. Affected file silcd/server.c.
3513 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3515 * Made the key generation options to the silcd program. Added
3516 -C option, equivalent to client's option.
3518 * Added new [ServerKeys] config section to the server. It
3519 configures the server's public and private key.
3521 * Defined generic Public Key Payload into the protocol
3522 specification to send specific type of public keys and
3525 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3526 public key or certificate.
3528 * Implemented the GETKEY command to the server and to the
3529 client library and on user interface.
3531 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3533 * Made preliminary `make install' work.
3535 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Added SilcServerRekey context into silcd/idlist.h.
3539 * Added the PFS support as defined in the specification to the
3540 SKE protocol. Affected files lib/silcske/*.c.
3542 * Added `ske_group' field to the SilcServerRekey context to hold
3543 the number of the SKE group that is used with PFS in re-key.
3544 Affected file silcd/idlist.h.
3546 * Added PFS re-key support to the server. Affected file is
3549 * Added silc_protocol_cancel to cancel execution of the next
3550 state of the protocol. Affected file is
3551 lib/silccore/silcprotocol.[ch].
3553 * Added the re-key support with and without PFS to the client
3554 library. Re-key is performed once in an hour, by default.
3556 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3557 Added silc_client_rekey_callback and silc_client_rekey_final.
3558 Affected files are lib/silcclient/protocol.[ch] and
3559 lib/silcclient/client.[ch].
3561 * Removed the `hmac_key' and `hmac_key_len' fields from the
3562 SilcClientConnection structure; not needed. Affected file is
3563 lib/silcclient/client.h.
3567 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Do not ask whether user wants to use the negotiated private key
3570 for private messages, just use it. Affected file is
3571 silc/local_command.c.
3573 * Added `send_enc_key' and `enc_key_len' fields to the
3574 SilcIDListData structure since they are needed in the re-key
3575 phase. Affected file is silcd/idlist.[ch].
3577 * Implemented the simple re-key protocol into the server.
3578 Affected files silcd/server.c and silcd/protocol.[ch]. The
3579 re-key will be performed once in an hour, by default.
3581 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3582 Added silc_server_rekey, silc_server_rekey_callback and
3583 silc_server_rekey_final.
3585 * Removed Tunneled flag from the protocol. Updated the code
3586 and the specifications.
3588 * Adde `pfs' field to the SilcIDListData to indicate whether
3589 the PFS is to be performed in the re-key. Affected file is
3592 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3595 int64 of at least the xintXX size. If void * is less that 4
3596 bytes uint32 * will be used. Defined bool as boolean.
3598 * Changed _ALL_ unsigned long and unsigned int to uint32,
3599 unsgined short to uint16 in the source tree.
3601 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3602 not handle clients that has entry->data.registered == FALSE.
3603 They are not in the network anymore. Affected file is
3606 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3608 * Implemented the sending of the SERVER_SIGNOFF notify in the
3609 server. Affected file is silcd/server.c.
3611 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3612 Added also silc_notify_payload_encode_args into the
3613 lib/silccore/silcnotify.[ch].
3615 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3616 Affected file silcd/packet_receive.c.
3618 * Implemented the SERVER_SIGNOFF notify handling in the client
3619 library. Affected file lib/silcclient/client_notify.c. Also,
3620 implemnted the printing of the SERVER_SIGNOFF info to the
3621 application. Affected file silc/client_ops.c.
3623 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3624 if the deleting was successful. Affected file silcd/idlist.[ch].
3626 * Added support for public key authentication in the connection
3627 authentication protocol in the client library. Affected file
3628 lib/silcclient/protocol.c.
3630 * Changed the server's silc_idlist_get_clients_by_* interface
3631 to support already allocated array so that new entries may be
3632 added to pre-allocated array. Affected file silcd/idlist.[ch].
3633 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3634 and command replies.
3636 * All command reply functions in the server now calls the
3637 pending command callback even if error occured. This way the
3638 error will be delivered to the client as well. Affected files
3639 silcd/command.c and silcd/command_reply.c.
3641 * Fixed INFO command to return local server's info if no server
3642 was provided. Affected file lib/silcclient/command.c.
3644 * Removed RESTART command for good. Updated the code and the
3647 * Rewrote parts of the task system. It is a bit simpler now.
3648 Removed unsued task priorities. The affected files are
3649 lib/silcutil/silctask.[ch].
3651 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3653 * Moved the USERS printing from the library to the application.
3654 Affected files lib/silcclient/command.c and silc/client_ops.c.
3656 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3660 * Added channel key re-key support. The re-key is perfomed
3661 only by the router and is done once in an hour. Added `rekey'
3662 field to the SilcChannelEntry in the server. Affected files
3663 silcd/server.c and silcd/idlist.h.
3665 * Added silc_task_unregister_by_context into the file
3666 lib/silcutil/silctask.[ch].
3668 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * Added SILC_UMODE_GONE mode to indicate when the client is not
3671 present in the SILC network. Added also support to the local
3672 command AWAY that will set this mode. Added support of showing
3673 "xxx is gone" in WHOIS command. The USERS command shows the
3674 gone status as well.
3676 * Fixed setting server and router operator privileges in the
3677 server's UMODE command. Affected file silcd/command.c.
3679 * Merged the SKE KE1 and KE2 payloads into one payload. The
3680 new KE payload is equivalent to the old KE2 payload.
3682 Cleaned up the SKE Start Payload parsing. It now uses the
3683 simple buffer unformatting to do the parsing. A lot faster
3686 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3687 to the SKE that is used to indicate whether both of the SKE
3688 parties should perform authentication. By default only the
3689 responder performs authentication. By setting this flag also
3690 the initiator must do authentication. By default it is unset
3691 since in normal SKE case, client to server connection, only
3692 the responder should do authentication. When doing SKE between
3693 two clients both should perform authentication. Updated the
3694 code and the protocol specs.
3696 * A little fix to IDENTIFY command in the server. Search the
3697 client first by hash not nickname. Affected file is
3700 * Fixed the silc_client_close_connection to support closing
3701 the client to client connections wihtout deleting too much
3702 data. Affected file lib/silcclient/client.c.
3704 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3705 are received if protocol used to be active but is not anymore
3706 the application would crash due to NULL pointer dereference.
3707 Affected files silcd/server.c and lib/silcclient/client.c.
3709 * Added `hash' field to the SilcClientConnection to include
3710 the hash function negotiated in the SKE protocol.
3712 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3713 to set the channel founder authentication data. A client can
3714 claim the founder rights later by providing the authentication
3715 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3716 This way the channel founder can regain the channel founder
3717 privileges even it is left the channel. This works only on
3718 local server and the client must be connected to the same
3719 server to be able to regain the founder rights. Updated the
3720 protocol specs accordingly.
3722 Added support to the CMODE command in the client to set the
3723 founder auth data. Read the README to see how to set it.
3725 Added support to the CUMODE command to claim the founder
3726 rights. Read the README to see how to do it.
3728 Added support for the founder authentication to the Channel
3729 Entry in the server. Affected file silcd/idlist.h.
3731 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3732 server's CMODE command. Affected file silcd/command.c.
3734 * Added the following new functions into lib/silccore/silcauth.[ch]:
3735 silc_auth_get_method and silc_auth_get_data.
3737 * The server now saves the remote hosts public key to the
3738 SilcIDListData pointer. Affected file silcd/protocol.c.
3740 * The normal server now does not remove the channel entry from
3741 the cache if the founder authentication data is set. It used
3742 to remove it if the founder was the last one on the channel on
3743 the server and left the channel. The auth data is saved and
3744 if the channel is re-joined later the old entry is used with
3745 the old auth data. Affected files silcd/command_reply.c and
3748 * Removed the `pkcs' field from the SilcIDListData structure
3749 in the server; it is not used. Affected file silcd/idlist.h.
3751 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Fixed packet processing on slow links. Partial packets were
3754 never re-processed because the incoming data buffer was cleared
3755 by the application. Application must not directly clear the
3756 sock->inbuf, the packet processing routines handle it. Fixed
3757 this in client library and in server.
3759 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Fixed the WHOIS and IDENTIFY send reply function to really
3762 check whether to send list or just one entry. Affected file
3765 * Cleaned up the LEAVE command's channel key distribution. The
3766 affected file silcd/command.c.
3768 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3769 can enforce the channel mode as well. In that case the ID
3770 includes the ID of the server. The code now enforces the
3771 mode change if the router have different mode than the server.
3773 * The notify client operation with CMODE_CHANGE notify can now
3774 return NULL client_entry pointer if the CMODE was not changed
3775 by client. Application must check for this.
3777 * Added <Server ID> argument to INFO command to support server
3778 info fetching by Server ID.
3780 * Added silc_server_announce_get_channel_users to get assembled
3781 packets of channel users of the specified channel. Affected
3782 file silcd/server.[ch].
3784 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3785 was freed underneath the ID Cache.
3787 * Re-announce clients when the server received CHANNEL_CHANGE
3788 notify from the router. Affected file silcd/packet_send.c.
3790 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3793 crashed since it did not handle the fact that there is no cipher
3794 called "3" and didn't check the error condition. Now fixed.
3796 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3797 flag. It can be used to send message requests.
3799 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Implemented the RESTART command in the client.
3803 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3804 notice type messages. Added notice printing to the user
3807 * The channel keys are not re-generated if the channel's mode
3808 is PRIVKEY, ie private key on the channel exists. Affected
3809 files silcd/server.c and silcd/command.c.
3811 * Fixed a little bug in channel message delivery when channel
3812 private keys are set in the server. Affected file is
3813 silcd/packet_send.c.
3815 * Changed the setting on channel->on_channel = TRUE from the
3816 silc_client_save_channel_key to the JOIN command reply. The
3817 key payload is not received if the private channel key is set.
3818 Affected file lib/silcclient/command_reply.c and the
3819 lib/silcclient/client_channel.c.
3821 * When the CMODE_CHANGE notify is sent and the channel private
3822 key mode is removed the channel key must be re-generated in
3823 other cells as well. Added this support for the router in the
3824 silcd/packet_receive.c.
3826 * Added new local command NOTICE to send notice message on
3827 channel. Affected file silc/local_command.[ch].
3829 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Added new local command ME to the client. It is used to send
3832 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3833 some action. Affected file silc/local_command.[ch].
3835 * Changed channel_message and private_message client operations
3836 to deliver the message flags to the application. Added also
3837 the `flags' arguments to the silc_client_send_channel_message
3838 and silc_client_send_private_message functions. Affected file
3841 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Redefined the Private Message Payload to support private message
3844 keys and to support the new private message flags. Updated
3845 the protocol specs. Flags makes it possible to have for example
3846 CTCP style messages.
3848 * Added new type SilcPrivateMessagePayload and defined an API
3849 for it in the lib/silcclient/silcprivate.[ch].
3851 * Tested private message private keys successfully. Tested the
3852 private message key set, unset and list commands with the new
3855 * Redefined the Channel Message Payload to include the channel
3856 message flags (equal with private message flags) to support
3857 for example CTCP style messages.
3859 * Defined some of the message (for channel and private message)
3860 flags. Updated the protocol specs and added the flags to the
3861 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3863 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Added SilcKeyAgreementStatus type to the key agreement routines
3866 to indicate the current status and error if one occured.
3867 The status types are defined in the lib/silcclient/silcapi.h.
3869 * Added new local command KEY that is used to set and unset private
3870 keys for channels, set and unset private keys for private messages
3871 with remote clients and to send key agreement requests and
3872 negotiate the key agreement protocol with remote client. The
3873 key agreement is supported only to negotiate private message keys,
3874 it currently cannot be used to negotiate private keys for channels,
3875 as it is not convenient for that purpose.
3877 * Fixed a minor pending callback setting bug in the function
3878 silc_client_get_client_by_id_resolve, now the function works.
3879 Affected file lib/silcclient/idlist.c.
3881 * Added function silc_net_get_local_port to get local bound
3882 port by socket. Added to lib/silcutil/silcnet.[ch].
3884 * Added `sockets' and `sockets_count' fields to the SilcClient
3885 object. They hold the sockets of the listenning sockets in
3886 the client. Listenning sockets may be for example the key
3887 agreement server. Affected file lib/silcclient/client.[ch].
3888 Added functions the silc_client_add_socket and the
3889 silc_client_del_socket. They are exported to the application
3892 * Added ~./silc/clientkeys to support other client's public keys.
3894 * Renamed verify_server_key client operation to verify_public_key
3895 and added one argument to indicate the type of the connection
3896 (server, client etc.).
3898 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * Added silc_server_connection_auth_request to handle the
3901 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3902 silcd/packet_receive.[ch].
3904 * Added silc_server_send_connection_auth_request into the
3905 silcd/packet_send.c to send the connection auth request packet.
3907 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3910 * Fixed the public key authentication in responder side in the
3911 server. The `auth_data' pointer includes the SilcPublicKey
3912 not the path to the public key. Affected file silcd/protocol.c.
3914 * Implemented the public key authentication in the initiator side
3915 in the server. Affected file silcd/protocol.c.
3917 * Removed the [RedirectClient] config section from the server
3918 configuration. Is not needed and I don't want to implement it.
3920 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3922 * Cleaned up the CMODE command in the server. It now works
3923 correctly and supports all the modes defined in the protocol.
3924 Affected file is silcd/command.c.
3926 * Added `hmac_name' field to the SilcChannelEntry in the server
3927 to hold the default HMAC of the channel. It can be set when
3928 creating the channel (with JOIN command). Affected files
3931 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3932 type to indicate the change of the current cipher and hmac
3933 on the channel. Client can safely ignore the <cipher> argument
3934 (if it chooses to do so) since the CHANNEL_KEY packet will
3935 force the channel key change anyway. The <hmac> argument is
3936 important since the client is responsible of setting the new
3937 HMAC and the hmac key into use.
3939 * Fixed the CMODE command in the client library as well.
3941 * Tested CMODE command in router environment successfully.
3943 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Show the version of the remote client (or server) when connecting
3946 to the server. It is logged to the log file. Affected file
3947 is silcd/protocol.c.
3949 * Fixed the KILLED notify handling in the client library. The
3950 client must be removed from all channels when receiving the
3953 Also, do not remove the client entry when giving the KILL
3954 command but when the KILLED notify is received.
3956 * Removed silc_idlist_find_client_by_nickname from the server.
3957 Not needed anymore. Affected files silcd/idlist.[ch].
3959 * Implemented the CHANNEL_CHANGE notify type handling to the
3960 server. Affected file silcd/server.c.
3964 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Added silc_server_send_notify_invite to send the INVITE
3967 notify between routers.
3969 * Implemented the INVITE command correctly to the server.
3971 * Implemented the INVITE notify type handling in the server.
3973 * Implemented the INVITE command to the client library and on the
3976 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3978 * Added function silc_server_get_client_resolve to find the
3979 client entry by ID from all ID lists and then resolve it
3980 (using WHOIS) if it cannot be found. Affected file is
3983 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Implemented the BAN command to the client library.
3987 * The JOIN command in the server now checks the invite list
3990 * Changed the silc_command_reply_payload_encode_va and the
3991 silc_command_payload_encode_va to support that if argument is
3992 NULL it ignores and checks the next argument. Affected file
3993 lib/silccore/silccommand.c.
3995 * Added silc_server_send_notify_ban to send the BAN notify
3996 type between routers.
3998 * Chaned the silc_notify_payload_encode to support that if
3999 argument is NULL it ignores and checks the next argument.
4000 Affected file lib/silccore/silcnotify.c.
4002 * Tested ban lists in router environment successfully.
4004 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4006 * Implemented BAN command to the server, in silcd/command.[ch].
4008 * Removed the BAN and INVITE_LIST modes from the CMODE command
4011 * Added function silc_string_match to regex match two strings.
4012 Affected files lib/silcutil/silcutil.[ch].
4014 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Redefined parts of the SilcChannelEntry in the server to support
4017 the new ban and invite lists.
4019 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Redefined the INVITE command. The same command can be used to
4022 invite individuals to the channel but also to manage the invite
4023 list of the channel (to add to and remove from the invite list).
4024 Updated the protocol specs.
4026 * Added new command SILC_COMMAND_BAN that can be used to manage
4027 the ban list of the channel. Updated the protocol specs.
4029 * Removed the channel modes: the SILC_CMODE_BAN and the
4030 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4031 in the CMODE command. The equivalent features are now available
4032 using INVITE and BAN commands. Updated the protocol specs.
4034 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4035 in the network about change in the current ban list. The notify
4036 type is not used by the client.
4038 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4039 support the invite lists.
4041 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Added new function silc_string_regexify that converts string
4044 including wildcard characters into regex string that can
4045 be used by the GNU regex library. Added into the file
4046 lib/silcutil/silcutil.[ch].
4048 Added silc_string_regex_combine to combine to regex strings
4049 into one so that they can be used as one regex string by
4050 the GNU regex library. Added into the file
4051 lib/silcutil/silcutil.[ch].
4053 Added silc_string_regex_match to match two strings. It returns
4054 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4056 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Imported GNU regex to the soruce tree into lib/contrib.
4059 Fixed some compiler warning from the regex.c.
4061 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Fixed MOTD command in the server to work in router environment.
4065 * Fixed the MOTD command in the client library to support
4066 the server argument in the command.
4068 * Added `nickname_len' argument to the silc_idlist_add_client
4069 in the server, as the `nickname' argument may be binary data
4072 * Added silc_idlist_get_channels to return all channels from
4075 * Implemented LIST command to the server. Affected file is
4078 * Implemented the LIST command to the client library and on the
4081 * Added [<user count>] argument to the LIST command reply.
4082 With private channels the user count is not shown.
4084 * Updated TODO and README.
4086 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * The client entry's data.registered must be TRUE even with
4089 global client entry on global client list. The data.registered
4090 is used to check whether the client is anymore in the network,
4091 for example with WHOWAS command so it must be valid.
4093 * Fixed the WHOWAS command in the server. It now actually works
4094 in router environment. Added function into silcd/command_reply.c
4095 silc_server_command_reply_whowas_save.
4097 * Added silc_idlist_purge function to the silcd/idlist.c
4098 to periodically purge the ID Cache.
4100 * Fixed INFO command in the server. It works now in router
4101 environment. Added <server name> argument to the INFO command
4102 reply. Updated the protocol specs.
4104 * Fixed minor bug in silc_idcache_purge to not purge if the
4105 expire value is zero.
4107 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4108 they were buggy because of the WHOWAS information.
4110 * Fixed local command MSG to handle the async resolving of
4111 the remote client properly. It used to fail the first MSG.
4112 Affected file silc/local_command.c.
4114 * Added `data_len' field to SilcIDCache context.
4116 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4118 * Update TODO. Todo in commands in the server.
4120 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4122 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4123 used by routers as broadcast packet to inform other routers
4124 about the changed user mode.
4126 Implemented the notify handling in the server. Affected file is
4127 silcd/packet_receive.c. Added the function
4128 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4130 * Added new generic Channel Payload and deprecated the New Channel
4131 Payload. The New Channel Payload is now the generic Channel
4134 * Added new argument `mode' to the silc_server_send_new_channel
4135 as it is required in the Channel Payload now.
4137 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4138 and created a new and real SilChannelPayload to represent the
4139 new generic Channel Payload. Implemented the encode/decode
4140 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4142 * Added silc_server_get_client_channel_list to return the list
4143 of channels the client has joined for WHOIS command reply.
4144 Affected file silcd/server.[ch].
4146 * Implemented the channel list sending in the WHOIS command reply
4147 in server and in the client.
4149 Implemented the channel list displaying on the user interface
4150 as well. Affected file silc/client_ops.c.
4152 * Added silc_channel_payload_parse_list to parse list of Channel
4153 Payloads. It returns SilcDList list of SilcChannelPayloads.
4154 Client for example can use this function to parse the list of
4155 channels it receives in the WHOIS command reply. The caller
4156 must free the list by calling silc_channel_payload_list_free.
4157 Affected files lib/silccore/silcchannel.[ch].
4159 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Added one new argument <user mode> to the WHOIS command reply
4162 to return the mode of the user in SILC. Updated the protocol
4165 Implemented it to the server and client.
4167 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Fixed the mode printing on the user interface on joining.
4170 Affected file silc/client_ops.c.
4172 * Implemented the UMODE command and user modes in general to the
4173 client library and to the user interface.
4175 * Implemented the UMODE command to the server.
4177 * The server now sends UNKNOWN_COMMAND error status if client sends
4178 unknown command. Affected file silcd/command.c.
4180 * All server commands now handle the command identifier the right
4181 way when sending the command reply to the client. The client can
4182 use to identify the command replies with the identifier.
4184 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Added silc_server_get_client_route to resolve the route to
4187 the client indicated by the client ID. Affected file is
4190 * Added silc_server_relay_packet as general function to relay
4191 packet to arbitrary destination. This deprecates functions
4192 like _send_private_message_key, _relay_notify etc. Affected
4193 file is silcd/packet_send.[ch].
4195 Removed silc_server_send_key_agreement,
4196 silc_server_send_private_message_key and
4197 silc_server_packet_relay_notify functions from the file
4198 silcd/packet_send.[ch].
4202 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4203 server. Affected file silcd/packet_receive.[ch].
4205 * Implemented the KILL command to the client. Implemented the
4206 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4207 Affected files lib/silcclient/command[_reply].c and
4208 lib/silcclient/client_notify.c. Implemented the KILL notify
4209 printing in the user inteface.
4211 * Fixed a lot silc_parse_nick memory leaks from the client
4212 library in the file lib/silcclient/command.c.
4214 * Changed the silc_server_send_notify_on_channels's `sender'
4215 argument from SilcSocketConnection to SilcClientEntry to
4216 check the sender as entry and not as connection object and not
4217 to send to the client provided as argument. The affected file
4218 is silcd/packet_send.[ch].
4220 * The notify packets that are destined directly to the client used
4221 to not to be processed by the server. Now changed that and the
4222 server processes all notify packets. After relaying the packet
4223 to the client the notify packet is processed in the server.
4225 * The silc_server_free_client_data now checks whether there is
4226 pending outgoing traffic for the client and purges the data to
4227 the network before removing the client entry.
4229 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4232 an client is killed from the SILC Network. Updated the protocol
4235 Added new function silc_server_send_notify_killed to the
4236 silcd/packet_send.[ch].
4238 * Added function silc_server_packet_relay_notify to relay notify
4239 packets that are destined directly to a client. In this case
4240 the server does not process the notify packets but merely relays
4241 it to the client. Affected file silcd/packet_send.[ch].
4243 Added also silc_server_packet_process_relay_notify to check
4244 whereto relay the notify. Affected file is
4245 silcd/packet_receive.[ch].
4247 * Implemented the KILL command to the server.
4251 * Added the backup schema desgined last fall to the protocol
4252 specs for everyone to see. The specification is in the
4253 *-spec-xx.txt draft and the packet type definitions for the
4254 backup routers is in *-pp-xx.txt draft. Thusly, added also
4255 new packet type SILC_PACKET_CELL_ROUTERS.
4257 * A big security problem in the implementation discovered. The
4258 signoff of an client did not cause new channel key generation
4259 which it of course should've done. The channel keys must be
4260 always re-generated when client leaves (or signoffs) the channel.
4261 The silc_server_remove_from_channels funtion now handles
4262 the channel key re-generation.
4264 * Added `sender' argument to the silc_server_send_notify_on_channels
4265 to not to send the client provided as argument. Affected file
4266 silcd/packet_send.[ch].
4268 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Implemented OPER and SILCOPER commands into the server and
4273 * Added silc_auth_verify and silc_auth_verify_data to verify
4274 the authentication directly from the authentication payload.
4275 It supports verifying both passphrase and public key based
4276 authentication. Affected file lib/silccore/silcauth.[ch].
4278 * Added `hash' field to the SilcIDListData structure. It is the
4279 hash negotiated in the SKE protocol. Affected file is
4282 * Slight redesigning of the SilcAuthPayload handling routines.
4283 Do not send SilcPKCS but SilcPublicKey as argument.
4285 * Implemented the public key authentication support to the
4286 serverconfig. The public key is loaded from the provided path
4287 and saved as authentication data to void * pointer. Thus,
4288 changed the unsigned char *auth_data to void *auth_data;
4290 * Fixed SHUTDOWN command to send the reply before the server
4291 is shutdown. :) Affected file silcd/command.c.
4293 * Fixed fatal bug in CONNECT command. The hostname was invalid
4294 memory and server crashed. Affected file silcd/command.c.
4296 * Fixed fatal bug in CLOSE command. The server_entry became
4297 invalid but was referenced later in the command. Affected file
4300 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Fixed fatal bug in failure packet handling. Server ignored
4303 the failure and thus crashed when it came.
4307 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4310 that the command may be executed only once in (about) 2 seconds.
4311 The old SILC_CF_LAG flag is same but allows command bursts up
4312 to five before limiting.
4314 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4315 server code. Various commands now includes the CF_LAG_STRICT
4316 flag to disallow any kind of miss-use of the command.
4318 * Fixed the silc_buffer_unformat to not to allocate any data
4319 if the length of the data is zero. It used to allocate the
4320 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4322 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Changed the format of AdminConnection configuration section
4325 in the server. Added username of the admin to the format.
4326 Affected files silcd/serverconfig.[ch].
4328 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4329 to return admin configuration data by host, username and/or
4332 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Implemented WHOWAS command to the server. Added the functions:
4336 silc_server_command_whowas_parse,
4337 silc_server_command_whowas_send_reply,
4338 silc_server_command_whowas_from_client and
4339 silc_server_command_whowas_from_server
4341 * Added <Client ID> argument to the WHOWAS command reply. Updated
4342 the protocol specs accordingly.
4344 * Implemented WHOWAS command and command_reply to the client
4347 Implemented the WHOWAS printing on the user interface.
4349 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Added new argument to the WHOWAS command reply, the real name.
4352 It is an optional argument. Updated the protocol specs.
4354 * Added SilcIDCacheDestructor callback that is registered when
4355 the SilcIDCache is allocated. The callback is called when
4356 an cache entry in the ID Cache expires, or is purged from the
4357 cache. Added into lib/silccore/idcache.[ch].
4359 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4360 to destruct the client entries when the cache entry expires.
4361 Other ID Cache's in server and in the client library ignores
4364 * If the ID Cache entry's `expire' field is zero then the entry
4365 never expires. Added boolean `expire' argument to the
4366 silc_idcache_add function in the lib/silccore/idcache.[ch].
4367 If it is TRUE the default expiry value is used.
4369 * Added silc_server_free_client_data_timeout that is registered
4370 when client disconnects. By default for 5 minutes we preserve
4371 the client entry for history - for WHOWAS command.
4373 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Added support to the server to enforce that commands are not
4376 executed more than once in 2 seconds. If server receives
4377 commands from client more frequently, timeout is registered
4378 to process the commands. Affected file silcd/command.c.
4379 Added new function silc_server_command_process_timeout.
4381 * Changed NICK_NOTIFY handling in client library to check that
4382 if the client's nickname was changed, so there is no need to
4383 resolve anything from the server.
4385 * Removed error printing from the WHOIS and IDENTIFY commands.
4386 If error occurs then it is ignored silently in the client library.
4387 The application, however, may map the received error to
4388 human readable error string. The application currently maps
4389 the NO_SUCH_NICKNAME error to string.
4391 * Made the command status message public to the application. Moved
4392 them from lib/silcclient/command_reply.c to
4393 lib/silcclient/command_reply.h. The application can map the
4394 received command status to the string with the
4395 silc_client_command_status_message function.
4397 * Added check to the server to check that client's ID is same
4398 as the Source ID in the packet the client sent. They must
4401 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Added dist-bzip hook to the Makefile.am to make bzip2
4404 compressed distributions.
4406 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Server now enforces the maximum length for the nickname and
4409 the channel as protocol specification dictates. 128 bytes for
4410 nickname and 256 bytes for channel name.
4412 * Moved the WHOIS printing to the application. The client libary
4413 does not print out the WHOIS information anymore, the application
4414 must do it. Renamed silc_client_command_reply_whois_print to
4415 the silc_client_command_reply_whois_save.
4417 The client's idle time is also sent to the application now, and
4418 the idle is shown on screen.
4420 * Added silc_client_command_reply_identify_save to save the
4421 received IDENTIFY entries.
4423 * Do not check for channel private keys in message sending and
4424 reception if the channel does not have the PRIVKEY mode set.
4425 Affected file lib/silclient/client_channel.c.
4427 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4430 just surfaced after chaning the JOIN procedure.
4432 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Added silc_client_get_clients_by_list to get client entries
4435 from Client ID list, that is returned for example by JOIN
4436 and USERS command replies. The application should use this
4437 function for example when JOIN command reply is received to
4438 resolve the clients already on the channel (library does not
4439 do that anymore as USERS command reply is not used in the JOIN
4440 procedure anymore). Affected files lib/silcclient/silcapi.h and
4441 lib/silcclient/idlist.c.
4443 * JOIN command reply and USERS command reply returns now SilcBuffer
4444 pointers instead of unsigned char pointers when returning
4445 the client list and mode list.
4447 * Added <Client ID> argument to the JOIN command reply, mainly
4448 for the server to identify for which client the command was
4449 originally sent. Updated protocol specs accordingly.
4451 * Added SilcDlist private_key pointer to the SilcChannelEntry
4452 in the client to support the channel private keys. Affected
4453 file is lib/silcclient/idlist.h.
4455 * Added SilcChannelPrivateKey argument to the function
4456 silc_client_send_channel_message so that application can choose
4457 to use specific private ke if it wants to. If it is not provided,
4458 the normal channel key is used, unless private keys are set.
4459 In this case the first (key that was added first) is used
4460 as the encryption key.
4462 * Implemented the support for channel private key handling.
4463 Implemented the following functions:
4465 silc_client_add_channel_private_key,
4466 silc_client_del_channel_private_keys,
4467 silc_client_del_channel_private_key,
4468 silc_client_list_channel_private_keys and
4469 silc_client_free_channel_private_keys
4471 Affected file lib/silcclient/client_channel.c.
4473 * Added the support for the private keys in the channel message
4474 sending and encryption and in the message reception and
4475 decryption. Affected funtions are
4476 silc_client_send_channel_message and silc_client_channel_message.
4478 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4480 * Added SKE's key verify callback to the client library's
4481 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4483 * Removed the statement that server (or router) must send USERS
4484 command reply when joining to the channel so that the client
4485 knows who are on the channel. Instead, the client list and
4486 client's mode list is now sent in the JOIN command reply to the
4487 client who joined channel. This is better solution.
4489 * Added function silc_server_get_users_on_channel and function
4490 silc_server_save_users_on_channel to the silcd/server.[ch].
4492 * Removed function silc_server_command_send_users from the
4495 * Do not show topic on the client library anymore. The topic is
4496 sent in the command reply notify to the application and the
4497 application must show the topic now.
4499 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Added client searching by nickname hash into the IDENTIFY and
4502 WHOIS commands in the server as they were clearly missing from
4503 them. Affected file is silcd/command.c.
4505 * Fixed a bug in private message receiving in the client library.
4506 The remote ID was freed and it wasn't supposed, now it is
4509 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4511 * Minor fix to the channel payload; allocate the data area, as it
4512 needs to be of specific length.
4514 * If the key agreement port is zero then the operating
4515 system will define the bound port. Affected files are
4516 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4518 * Added new function silc_channel_payload_decrypt into the file
4519 lib/silccore/silcchannel.[ch].
4521 * Moved the channel message etc, check from silc_packet_decrypt
4522 to applications. The library calls now a generic
4523 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4524 when the packet is either normal or special. This was done to
4525 allow more wide range of checking that was not allowed when
4526 the code was in library. Now applications can do virtually any
4527 checks to the packet and return to the library the decision how
4528 the packet should be processed. Affected files are
4529 lib/silccore/silcpacket.[ch].
4531 Added silc_server_packet_decrypt_check to the server and
4532 silc_client_packet_decrypt_check to the client library.
4534 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4535 to send with specified source and destination information.
4537 * Channel message delivery between routers was broken after the
4538 channel key distribution was fixed earlier. The channel key
4539 was used be to distributed to other routers as well which is not
4540 allowed by the protocol. Now this is fixed and channel keys
4541 really are cell specific and the channel message delivery between
4542 routers comply with the protocol specification.
4544 * Fixed various commands in server to check also the global list
4545 for the channel entry and not just the local list. The affected
4546 file silcd/command.c.
4548 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Added assert()s to buffer formatting and unformatting routines
4551 to assert (if --enable-debug) when error occurs. Affected
4552 file: lib/silcutil/silcbuffmt.c.
4554 * Changed to auto-reconnect to check whether the remote host is
4555 router and register the re-connect timeout if it is. It used
4556 to check that whether we are normal server, but router must do
4557 auto-reconnect with another router as well. Affected file
4560 * Removed the [<key len>] option from CMODE command as the cipher
4561 name decides the key length, nowadays. See the defined ciphers
4562 from the protocol specification.
4564 * Added [<hmac>] option to the CMODE command to define the HMAC
4565 for the channel. Added SILC_CMODE_HMAC channel mode.
4567 * Added [<hmac>] option for the JOIN command so that user can
4568 select which HMAC is used to compute the MACs of the channel
4571 * Added Hmac field to the Channel Message Payload. The integrity
4572 of plaintext channel messages are now protected by computing
4573 MAC of the message and attaching the MAC to the payload. The
4574 MAC is encrypted. Now, it is clear that this causes some
4575 overhead to the size of the packet but rationale for this is that
4576 now the receiver can verify whether the channel message decrypted
4577 correctly and also when private keys are set for the channel the
4578 receiver can decrypt the packet with several keys and check from
4579 the MAC which key decrypted the message correctly.
4581 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4582 lib/silccrypt/silccipher.[ch].
4584 * Added silc_hash_len to return the digest length into the
4585 lib/silcrypt/silchash.[ch].
4587 * Rewrote parts of Silc Channel Payload interface in the
4588 lib/silccore/silcchannel.[ch]. The encode function now also
4589 encrypts the packet and parse function decrypts it.
4591 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Fixed a minor formatting bug in the SKE's key material processing.
4594 It actually might have processed the keys wrong way resulting
4597 * Redefined the mandatory HMAC algorithms and added new algorithms.
4598 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4599 and hmac-md5 truncated to 96 bits. The mandatory is now
4600 hmac-sha1-96. Rest are optional (including the one that used
4601 to be mandatory). Rationale for this is that the truncated HMAC
4602 length is sufficient from security point of view and can actually
4603 make the attack against the HMAC harder. Also, the truncated
4604 HMAC causes less overhead to the packets. See the RFC2104 for
4607 * Added new [hmac] configuration section. The SKE used to use
4608 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4609 is of course wrong. The official names that must be proposed in
4610 the SKE are the ones defined in the protocol specification
4611 (hmac-sha1-96 for example). The user can configure any hmac
4612 using any hash function configured in the [hash] section. At
4613 least, the mandatory must be configured.
4615 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4617 * Added HMAC list to the SKE proposal list. It has now both
4618 hash algorithm list and HMAC list. This makes the protocol
4619 incompatible with previous versions. The SKE now seems to work
4620 the way it is supposed to work, for the first time actually.
4622 * Defined plain Hash algorithms to the protocol specification.
4625 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4627 * Implemented support for key agreement packets into the server.
4628 Added functions silc_server_key_agreement and
4629 silc_server_send_key_agreement. Other than these functions,
4630 server has nothing to do with this packet.
4632 * Added support for private message key packets into the server.
4633 Added functions silc_server_private_message_key and
4634 silc_server_send_private_message_key.
4638 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4639 called in the protocol's final callback instead in the END
4640 protocol state. This makes a little more sense and in the same
4641 time in client we can use the same protocol routines for normal
4642 key exchange and to key agreement packet handling as well.
4644 * Added to both client's and server's KE protocol context the
4645 SilcSKEKeyMaterial pointer to save the key material. We will
4646 bring the key material to the protocol's final callback by doing
4647 this. The final callback must free the key material.
4649 * Added SKE's packet_send callback into client's KE protocol
4650 context so that the caller can choose what packet sending function
4651 is used. This way we can use different packet sending when
4652 doing normal SKE when doing key agreement packet handling (in
4653 the key agreement packet handling we do not want to encrypt
4656 * Implemented the responder side of the key agreement routines
4657 in the client. The client can now bind to specified port and
4658 accept incoming key negotiation. The key material is passed
4659 to the application after the protocol is over.
4661 * Implemented the processing of incoming Key Agreement packet
4662 in the client. Added function silc_client_key_agreement to
4665 * Implemented the intiator side of the key agreement routines
4666 in the client. The client can now initiate key agreement with
4667 another remote client. The key material is passed to the
4668 application after the protocol is over.
4670 * Created client_keyagr.c to include all the key agreement
4673 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4674 SILC_TASK_CALLBACK except that it is not static.
4676 * Created client_notify.c and moved the Notify packet handling
4677 from the client.[ch] into that file.
4679 * Created client_prvmsg.c and moved all private message and
4680 private message key routines from the client.[ch] into that file.
4682 * Create client_channel.c and moved all channel message and
4683 channel private key routines from the client.[ch] into that file.
4685 * Changed silc_client_get_client_by_id_resolve to resolve with
4686 WHOIS command instead of IDENTIFY command, in the file
4687 lib/silclient/idlist.c.
4689 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Implemented the SKE's responder side to the Client library.
4693 * When FAILURE is received to the protocol do not trust it
4694 blindly. Register a timeout to wait whether the remote closes
4695 the connection as it should do it, only after that process the
4696 actual failure. This was changed to both client and server.
4698 * Added client_internal.h to include some of the structures
4699 there instead of client.h in lib/silcclient/.
4701 * Added function silc_task_unregister_by_callback to unregister
4702 timeouts by the callback function.
4704 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Some "Incomplete WHOIS info" errors has been appearing on the
4707 log files. Took away the entry->userinfo check from WHOIS
4708 reply sending. The entry->userinfo is now " " if client did not
4709 provide one. I thought this was fixed earlier but something
4710 is wrong still. Let's see if the error still appears.
4712 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Fixed a minor bug in the login when the channel key is
4715 re-generated in the server. It used to generate the key in
4716 wrong order and thus caused problems in the channel traffic.
4718 * Fixed a minor bug in channel key distsribution after
4719 KICK command. The key was not sent to the router even though
4722 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Added silc_ske_process_key_material_data as generic routine
4725 to process any key material as the SILC protocol dictates. The
4726 function is used by the actual SKE library but can be used by
4727 applications as well. This relates to the private message keys
4728 and the channel private keys since they must be processed the
4729 same way the normal SILC session keys. The protocol dictates
4730 this. Affected files: lib/silcske/silcske.[ch].
4732 Added also silc_ske_free_key_material to free the
4733 SilcSKEKeyMaterial structure.
4735 * Defined silc_cipher_set_key function to set the key for
4736 cipher without using the object's method function. The affected
4737 files: lib/silccrypt/silccipher.[ch].
4739 * Implemented silc silc_client_add_private_message_key,
4740 silc_client_add_private_message_key_ske,
4741 silc_client_del_private_message_key,
4742 silc_client_list_private_message_keys and
4743 silc_client_free_private_message_keys functions in the
4746 Added functions silc_client_send_private_message_key to send
4747 the Private Message Key payload and silc_client_private_message_key
4748 to handle incoming Private Message Key payload.
4750 * Added Cipher field to the Private Message Key payload to set
4751 the cipher to be used. If ignored, the default cipher defined
4752 in the SILC protocol (aes-256-cbc) is used.
4754 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Removed lib/silcclient/ops.h file.
4758 Redefined parts of the SILC Client Library API. Created new
4759 file silcapi.h that deprecates the ops.h file and defines the
4760 published Client Library API. Defined also private message key
4761 API and channel private key API into the file.
4763 This is the file that the application must include from the
4764 SILC Client Library. Other files need not be included by
4765 the application anymore.
4767 * Added new key_agreement client operation callback and also
4768 defined the Key Agreement library API for the application.
4770 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4772 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4773 is used by clients to request key negotiation between another
4774 client in the SILC network. If the negotiation is started it
4775 is performed using the SKE protocol. The result of the
4776 negotiation, the secret key material, can be used for example
4777 as private message key.
4779 Implemented the Key Agreement payload into the files
4780 lib/silccore/silauth.[ch].
4782 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Redefined ciphers for the SILC protocol. Added some new ciphers
4785 and defined the key lengths for the algorithms. Changed the
4786 code accordingly. The default key length is now 256 bits.
4788 * Fixed SKE key distribution function silc_ske_process_key_material
4789 when the key length is more than 128 bits. The default key
4790 length in SILC is now 256 bits.
4792 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4793 to indicate unsupported algorithm.
4795 * Renamed rijndael.c to aes.c and all functions as well.
4797 * Fixed a long standing channel key setting bug in client library.
4798 Weird that it has never surfaced before.
4800 * Fixed bug in channel deletion. If the entire channel is removed
4801 then it must also delete the references of the channel entry
4802 from the client's channel list as the client's channel entry and
4803 the channel's client entry share same memory.
4805 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Implemented CONNECT and SHUTDOWN commands in the client.
4809 * Implemented CLOSE command to the client.
4811 * Added the function silc_idlist_find_server_by_name into the
4812 files silcd/idlist.[ch].
4814 Added the function silc_idlist_find_server_by_conn into the
4815 files silcd/idlist.[ch].
4817 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * DIE command was renamed to SHUTDOWN. Updated the both code
4822 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4823 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4825 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4828 * Added function silc_server_create_connection function to create
4829 connection to remote router. My server implementation actually
4830 does not allow router to connect to normal server (it expects
4831 that normal server always initiates the connection to the router)
4832 so the CONNECT command is only good for connecting to another
4835 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4838 or some other client was kicked from the channel.
4840 Implemented the handling of the notify type to both client
4843 Implemented silc_server_send_notify_kicked to send the KICKED
4844 notify. It is used to send it to the server's primary router.
4846 * Implemented the KICK command into server and client.
4848 * Added `query' argument to the silc_idlist_get_client function
4849 to indicate whether to query the client from server or not if
4852 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4853 to indicate that the client is not channel founder.
4857 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * Removed the rng context from SilcPacketContext structure and
4860 changed that the packet routine uses the Global RNG API.
4862 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Added support for quit message that client can "leave" on the
4865 channel when it quits the SILC. It is ditributed inside the
4866 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4868 Added silc_server_free_client_data that will take the
4869 signoff message as argument.
4871 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4873 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Updated parts of the protocol specification to keep it up
4878 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4881 payloads in one packet.
4883 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4884 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4885 use now the new List flag.
4887 * Also deprecated the following packet types: REPLACE_ID,
4888 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4890 * Added list support for Notify packet in server.
4892 * Added silc_server_send_notify_channel_change to send the
4893 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4894 the silc_server_send_replace_id.
4896 * Added silc_server_send_notify_nick_change to send the
4897 NICK_CHANGE notify type. Deprecates the function
4898 silc_server_send_replace_id.
4900 * Added silc_server_send_notify_join to send the JOIN notify type.
4901 Deprecates the function silc_server_send_new_channel_user.
4903 * Added silc_server_send_notify_leave to send LEAVE notify type.
4904 Deprecates the function silc_server_send_remove_channel_user.
4906 * Added silc_server_send_notify_cmode and
4907 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4908 types. Deprecates the silc_server_send_set_mode function.
4910 * Added SERVER_SIGNOFF notify type to indicate that server has
4911 quit. This means that all clients on the channel from that
4912 server will drop. This can be also used when netsplit happens.
4914 Deprecated REMOVE_ID packet type since it is not needed anymore
4917 Added silc_server_send_notify_server_signoff to send the
4918 SERVER_SIGNOFF notify type. Deprecates the function
4919 silc_server_send_remove_id.
4921 Added also silc_server_send_notify_signoff to send the
4922 SIGNOFF notify type.
4924 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4925 SILC protocol from this day on. Changed the protocol
4926 specification as well.
4928 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4929 notify type. It is used between routers to notify about
4930 topic changes on a channel.
4932 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4935 * Partly updated the protocol specification to comply with the
4936 changes now made. It is still though a bit outdated.
4938 * The JOIN notify type now takes one extra argument <Channel ID>.
4939 The packet used to be destined to the channel but now the
4940 JOIN type may be sent as list thus it is impossible to
4941 destine it to any specific channel. By adding this argument
4942 it is again possible.
4944 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4946 * Added CREDITS file. The CHANGES and CREDITS file will appear
4947 in the distribution as well.
4949 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4951 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4952 types in the server's silcd/packet_receive.c.
4954 * Implemented CMODE and CUMODE to work in router environment.
4956 * Fixed minor encoding and decoding buglet from the
4957 lib/silccore/silcmode.c.
4959 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4962 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4964 * Changed all SilcConfigServer* and silc_config_server* to
4965 SilcServerConfig* and silc_server_config*, respectively.
4968 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Associated the ID (client or server ID) to the Authentication
4971 Payload to avoid any possibility of forging. Updated the
4972 protocol specification and the code accordingly.
4974 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * The RSA key length is now save to the RsaKey context in the
4977 key generation process in lib/silccrypt/rsa.c. The key length
4978 is now used to figure out the maximum size of the block allowed
4979 to be encrypted/signed.
4981 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4982 is equivalent to the silc_mp_mp2bin but does not allocate any
4985 * Changed silc_mp_mp2bin API to take length argument. If it is
4986 non-zero then the buffer is allocated that large. If zero, then
4987 the size is approximated using silc_mp_sizeinbase, which however
4990 * Created Global RNG API which is global RNG that application can
4991 initialize. After initializing, any routine anywhere in the
4992 code (including library) can use RNG without allocating a new
4993 RNG object. This was done to allow this sort of use of the
4994 RNG in code that has no chance to allocate RNG object. All
4995 applications currently allocate this and many routines in the
4996 library use this. Affected file lib/silccrypt/silcrng.[ch].
4998 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4999 it to use the Global RNG API.
5001 * Defined Authentication Payload into protocol specification that
5002 is used during SILC session to authenticate entities. It is
5003 used for example by client to authenticate itself to the server
5004 to obtain server operator privileges.
5006 Implemented this payload into the lib/silccore/silcauth.[ch].
5007 Implemented also routines for public key based authentication
5008 as the new protocol specification dictates.
5010 Moved definitions of different authentication methods from
5011 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5013 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5014 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5015 silc_pkcs_verify_with_hash functions into the file
5016 lib/silccrypt/silcpkcs.[ch].
5018 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * The client entry's userinfo pointer must be always valid.
5021 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5022 will fail since it requires the userinfo. Now, the userinfo
5023 is allocated as "" if actual userinfo does not exist. Actually,
5024 it must exist and it is totally Ok to drop client connections
5025 that does not announce the userinfo. However, we will make
5026 this workaround for now.
5028 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5029 to return the remote port by socket.
5031 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5034 SILC_SERVER_PENDING_EXEC and added an new macro
5035 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5036 data or when error occurs while processing the pending command.
5038 Added new argument `destructor' into silc_server_command_pending
5039 and to the SilcServerCommandPending object. This destructor is
5040 now called after calling the pending callback or if error occurs
5041 immediately. If error occurs the actual pending callback won't
5042 be called at all - only the destructor. The destructor may be
5043 NULL if destructor is not needed.
5045 All this applies for client library code as well. Similar
5046 changes were made there as well for the pending commands.
5048 In the client, the application must now allocate the
5049 SilcClientCommandContext with the silc_client_command_alloc
5052 * Added reference counter to the SilcServerCommandContext. Added
5053 function silc_server_command_alloc and silc_server_command_dup
5056 Same type of functions added to the client library for the same
5059 * Removed the cmd_ident from IDListData away since it is now
5060 global for all connections. It is the command identifier used
5061 in command sending and with pending commands. The affected file
5064 * Added reference counter to the SilcSocketConnection objecet to
5065 indicate the usage count of the object. The object won't be
5066 freed untill the reference counter hits zero. Currently only
5067 server uses this, and client ignores it. The client must be
5068 set to use this too later. The affected files are
5069 lib/silccore/silcsockconn.[ch]. Added also the function
5070 silc_socket_dup to increase the reference counter.
5072 This was mainly added because it is possible that the socket
5073 is removed underneath of pending command or other async
5074 operation. Now it won't be free'd and proper DISCONNECTING
5075 flags, etc. can be set to avoid sending data to connection that
5076 is not valid anymore.
5078 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5079 the connection. After that it sets SILC_SET_DISCONNECTED.
5080 It is, however, possible that the socket data is not still freed.
5081 The silc_server_packet_process now checks that data is not
5082 read or written to connection that is DISCONNECTED. The socket
5083 get's freed when the reference counter hits zero.
5085 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Changed the client operation API: channel_message operation's
5088 `sender' is now the client entry of the sender, not the nickname
5089 and the `channel' is the channel entry, not the channel name.
5091 In the private_message operation the `sender' is now also the
5092 client entry of the sender not the nickname.
5094 Affected file is lib/silcclient/ops.h and all applications
5095 using the client operations.
5097 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5099 * Moved the calling of ops->connect() from connect_to_server_final
5100 into receive_new_id functin since that is the point when the
5101 client is actually allowed to send traffic to network. The
5102 affected file is lib/silcclient/client.c.
5104 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5107 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5108 (if needs broadcasting) instead of broadcasting the packets one
5109 by one which would make a burst in the network traffic.
5111 * Added `broadcast' argument to the functions in silcd/server.[ch]
5112 silc_server_create_new_channel[_with_id] to indicate whether
5113 to send New Channel packet to primary router.
5115 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5117 * Added new function into the silcd/server.[ch] files:
5118 silc_server_create_new_channel_with_id to create new channel with
5119 already existing Channel ID.
5121 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5122 lib/silccore/silcpacket.h. This packet is used t send list of
5123 Set Mode payloads inside one packet. Server uses this to set
5124 the modes for the channels and clients on those channels, that it
5125 announced to the router when it connected to it. The protocol
5126 specification has been updated accordingly.
5128 * The silc_server_new_channel did not handle the packet coming
5129 from normal server as it normally does not send that. However,
5130 when it announces its channels it does send it. Implemented
5131 the support for that.
5133 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5134 into the file lib/silccore/id.h.
5136 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Fixed memory leaks in the functions silc_idlist_del_client,
5139 silc_idlist_del_channel and silc_idlist_del_server in the file
5140 silcd/idlist.c. All of those leaked like a sieve.
5142 * Fixed some small memory leaks in the client's function
5143 silc_client_notify_by_server.
5145 * Added functions into silcd/server.c: silc_server_announce_clients,
5146 silc_server_announce_channels and silc_server_announce_server.
5147 These functions are used by normal and router server to announce
5148 to its primary router about clients, channels and servers (when
5149 router) that we own. This is done after we've connected to the
5152 These functions effectively implements the following packet types:
5153 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5154 and SILC_PACKET_NEW_ID_LIST.
5156 * Added new functions into the silcd/packet_receive.[ch]:
5157 silc_server_new_id_list, silc_server_new_channel_list and
5158 silc_server_new_channel_user_list to handle the incoming
5159 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5161 * Added support of changing Channel ID in the function
5162 silc_server_replace_id. If the server that announces a channel
5163 to the router already exists in the router (with same name but
5164 with different Channel ID), router is responsible to send
5165 Replace ID packet to the server and force the server to change
5166 the Channel ID to the one router has.
5168 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5169 client that the Channel ID has been changed by the router. The
5170 normal server sends this to the client. Client must start using
5171 the new Channel ID as the channel's ID.
5173 Implemented handling of this new type into lib/silcclient/client.c
5174 into the function silc_client_notify_by_server.
5176 * Added new function silc_idlist_replace_channel_id into the files
5177 silcd/idlist.[ch] to replace the Channel ID.
5179 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Call silc_server_command_identify_check always when processing
5182 the IDENTIFY command in silcd/command.c
5184 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5186 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5187 send keepalive packets. The packet can be sent by clients,
5188 servers and routers.
5190 Added function silc_socket_set_heartbeat into the file
5191 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5192 If not set, the heartbeat is not performed. The actual
5193 heartbeat is implemented in the low level socket connection
5194 library. However, application is responsible of actually
5197 Added silc_server_send_heartbeat to send the actual heartbeat
5198 packet into silcd/packet_send.[ch]. Server now performs
5199 keepalive with all connections.
5201 * Added silc_task_get_first function into lib/silcutil/silctask.c
5202 to return the timeout task with shortest timeout. There was a bug
5203 in task unregistration that caused problems. TODO has been
5204 updated to include that task system must be rewritten.
5206 * The client library will now resolve the client information when
5207 receiving JOIN notify from server for client that we know but
5208 have incomplete information.
5210 * Rewrote parts of silc_server_remove_from_channels and
5211 silc_server_remove_from_one_channel as they did not remove the
5212 channel in some circumstances even though they should've.
5214 * Encryption problem encountered in server:
5216 The LEAVE command used to send the Channel Key packet to the
5217 router immediately after generating it. However, the code
5218 had earlier sent Remove Channel user packet but not immediately,
5219 ie. it was put to queue. The order of packets in the router
5220 was that Channel Key packet was first and Remove Channel User
5221 packet was second, even though they were encrypted in the
5222 reverse order. For this reason, MAC check failed. Now, this
5223 is fixed by not sending the Channel Key packet immediately but
5224 putting it to queue. However, this is more fundamental problem:
5225 packets that are in queue should actually not be encrypted
5226 because packets that are sent immediately gets encrypted
5227 actually with wrong IV (and thus MAC check fails). So, packets
5228 that are in queue should be encrypted when they are sent to
5229 the wire and not when they put to the queue.
5231 However, the problem is that the current system has not been
5232 designed to work that way. Instead, the packet is encrypted
5233 as soon as possible and left to the queue. The queue is then
5234 just purged into wire. There won't be any fixes for this
5235 any time soon. So, the current semantic for packet sending
5238 o If you send packet to remote host and do not force the send
5239 (the packet will be in queue) then all subsequent packets to the
5240 same remote host must also be put to the queue. Only after the
5241 queue has been purged is it safe again to force the packet
5244 o If you send all packets immediately then it safe to send
5245 any of subsequent packets through the queue, however, after
5246 the first packet is put to queue then any subsequent packets
5247 must also be put to the queue.
5249 Follow these rules and everything works fine.
5251 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * Added new function silc_server_remove_clients_by_server to
5254 remove all client entries from ID list when the server connection
5255 is lost. In this case it is also important to invalidate all
5256 client entires as they hold the invalid server entry. This
5257 fixes fatal bug when server has lost connection and will reconnect
5260 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Made some sanity checks to silc_server_daemonise like to check
5263 whether the requested user and group actually exists.
5265 * Added sanity check to SKE's silc_ske_responder_finish to check
5266 that the public and private key actually is valid.
5268 * Invalidate the client's nickname when receiving Replace ID
5269 packet and the Client ID is being replaced. This means that the
5270 server will query the nickname if someone needs it (client)
5273 * Sort the ID Cache in client library when the ID Cache data
5274 has changed (needs sorting).
5276 * Do not allow for SILC client to create several connections to
5277 several servers. The client does not support windows right now
5278 and generating multiple connections causes weird behaviour.
5280 Irssi-silc client does support windows and can handle several
5281 connections without problems, see: www.irssi.org and SILC plugin.
5283 * Fixed some places where client was added to the IDList. The
5284 rule of thumb is following (in order to get everything right):
5285 If the client is directly connected local client then the
5286 `connection' argument must be set and `router' argument must be
5287 NULL to silc_idlist_add_client function. If the client is not
5288 directly connected client then the `router' argument must
5289 bet set and the `connection' argument must be NULL to the
5290 silc_idlist_add_client function.
5292 * The funtion silc_server_packet_send_local_channel actually did
5293 not check whether the client was locally connected or not. It
5294 does that now. Fixed a bug related to LEAVE command.
5296 * Fixed Remove Channel User payload parsing bug in server's
5297 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5299 * The server's silc_server_save_channel_key now checks also the
5300 global ID list for the channel as it might not be in the local
5301 list. Fixed a bug related to LEAVE command.
5303 * Is this the end of the [<unknown>] buglet that has been lurking
5304 around for a long time? A little for loop fix in server's
5305 silc_server_command_whois_parse that is used by both IDENTIFY
5306 and WHOIS command. At least, this was a clear bug and a cause
5307 of one type of [<unknown>] buglet.
5309 * WHOIS and IDENTIFY commands call the function
5310 silc_server_command_[whois/identify]_check function even if
5311 we are not router server.
5313 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * Added --with-gmp configuration option. If set the GMP
5316 is always compiled in the SILC source tree. If not set then
5317 it is checked whether the system has the GMP3 installed. If
5318 it has then the GMP won't be compiled (the system's headers
5319 and library is used), if it doesn't have it then the GMP is
5320 compiled in the SILC source tree.
5322 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Changed RSA private exponent generation to what PKCS #1
5325 suggests. We try to find the smallest possible d by doing
5326 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5327 not security fix but optimization.
5329 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Added new config entry [Identity] to fork the server and run
5332 it as specific user and group. A patch from Bostik.
5334 * Imported Dotconf configuration library into lib/dotconf.
5335 This will be used to create the SILC configuration files later.
5336 It will appear in the distsribution after this commit.
5338 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * A big code auditing weekend happening. Auditing code for
5341 obvious mistakes, bugs and errors. Also, removing any code
5344 Removed files for being obsolete:
5346 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5347 inline in the file lib/silcutil/silcbuffer.h)
5349 o lib/silcutil/silcbufutil.c (the header has inline versions)
5351 Changed code to fix possible error conditions:
5353 o The buffer formatting routines now check that the destination
5354 buffer really has enough space to add the data. This applies for
5355 both buffer formatting and unformatting
5356 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5357 unformatting was changed to accomodate following rules:
5358 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5359 sent to the function while XXX_*STRING will not allocate or copy
5360 the data into the buffer. Instead it sets the pointer from the
5361 buffer into the pointer sent as argument (XXX_*STRING used to
5362 require that the pointer must be allocated already). This change
5363 makes this whole thing a bit more consistent and more optimized
5364 (note that the data returned in the unformatting with XXX_*STRING
5365 must not be freed now). The routines return now -1 on error.
5367 o Tried to find all code that use buffer_format and buffer_unformat
5368 and added return value checking to prevent formatting and
5369 especially unformatting errors and possible subsequent fatal
5372 o Changed ske->x and ske->KEY to mallocated pointers in
5373 lib/silcske/silcske.h. Fixed possible data and memory leak.
5375 o Added return value checking to all *_parse* functions. Fixed
5376 many memory leaks as well.
5378 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5379 so that buffer overflows would not happen. All code now also
5380 checks the return value as it can fail.
5382 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Added reconnection support to server if the normal server looses
5385 its connection to the router (for example if router is rebooted).
5386 The server performs normal reconnection strategy implemented
5387 to the server. Affected file silcd/server.c.
5389 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Added new packet type SILC_PACKET_SET_MODE that is used to
5392 distribute the information about changed modes (for clients,
5393 channels and clients channel modes) to all routers in the
5394 network. Updated the protocol specification accordingly.
5396 Added functions into silcd/packet_send.c and
5397 silcd/packet_receive.c: silc_server_send_set_mode,
5398 silc_server_set_mode.
5400 Added new files silcmode.[ch] into lib/silccore that implements
5401 the encoding and decoding of Set Mode Payload. Added new type
5402 SilcSetModePayload. Moved the definitions of different modes
5403 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5405 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Oops, a little mistake in server's connection authentication
5408 protocol. The protocol is not ended with FAILURE but with
5409 SUCCESS if the authentication is Ok. :) Affected file is
5412 * Implemented NICK_CHANGE notify handling in server in the file
5413 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5414 the local clients on the channel. After the changing nickname
5415 in router environment snhould work and the [<unknown>] nickname
5416 should appear no more.
5418 The silc_server_replace_id function that receives the Replace ID
5419 payload now sends the NICK_CHANGE notify type also in the file
5420 silcd/packet_receive.c
5422 * Changed WHOIS and IDENTIFY command to support the maximum amount
5423 of arguments defined in protocol specs (3328 arguments). This
5424 fixed a bug that caused problems when there were more than three
5427 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Added extra parameter, command identifier, to the
5430 silc_client_send_command so that explicit command identifier
5433 Changed that ID list routines uses specific command identifier
5434 when sending WHOIS/IDENTIFY requests to the server so that they
5435 can be identified when the reply comes back.
5437 Affected files lib/silcclient/command.[ch],
5438 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5440 * Added `sender' argument to silc_server_packet_send_to_channel
5441 to indicaet the sender who originally sent the packet to us
5442 that we are now re-sending. Ignored if NULL. Affected file
5443 silcd/packet_send.[ch].
5445 * Added some server statistics support in silcd/server_internal.h
5446 SilcServerStatistics structure and around the server code. Also
5447 send some nice statistics information when client is connecting
5450 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Fixed channel ID decoding in server's JOIN command reply in
5453 silcd/command_reply.c
5455 * Fixed braodcasting of replace ID payload to not to send it if
5456 we are standalone server in silcd/packet_receive.c.
5458 * Fixed all channel message sending routines to not to send
5459 packets to clients that has router set, since they are routed
5460 separately in the same function earlier. Affects file
5461 silcd/packet_send.c and all channel packet sending functions.
5463 * In USERS reply, res_argv[i] are not allocated, the table
5464 is allocated. Thus changed that free the table, not its
5467 * In server's whois_check and identify_check if the client is
5468 locally connected do not send any WHOIS commands - they are not
5471 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Fixed some minor bugs in client when sending WHOIS command. The
5474 arguments was in wrong order.
5476 * Removed statis function add_to_channel from server in
5477 silcd/command.c that was previously used with the joining but
5480 * Tested USERS command in router environment successfully with two
5481 routers, two servers and two clients.
5483 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Reorganized the USERS command and command reply in client library
5486 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5487 When the command is given by user we register a pending command
5488 callback that will reprocess the command after the reply has been
5489 received from the server. When reprocessing the packet we then
5490 display the information. Thus, the USERS information is displayed
5491 now in the command callback instead of in the command reply
5492 callback. The processing of the command is same as previously
5493 when server has sent the command reply in the JOINing process.
5495 * Added to USERS command in silcd/command_reply.c to join the client,
5496 we didn't use to know about, to the channel after we've created
5497 a client entry for it. Also, for clienet we did know already still
5498 check whether it is on the channel or not and add it if not.
5500 * Removed silc_server_command_join_notify as the function and its
5503 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5505 * Changed the client's pending command handling to the same as the
5506 server's pending command handling. It is also now possible to
5507 execute command reply functions from other command reply
5508 function as the function callbacks for commands and command
5509 replies are one and same. The pending commands are not static
5510 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5511 in client connection context. Thus, pending commands are server
5512 connection specific as it is convenient.
5514 Changed the function silc_client_command_pending and
5515 silc_client_command_pending_del and added new function
5516 silc_client_command_pending_check. Removed the
5517 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5520 * Added cmd_ident, current command identifier, to the client
5521 connection context in lib/silcclient/client.h to keep track on
5522 command identifiers used in command sending. Client's command reply
5523 function handling now supports the mandatory command identifiers.
5525 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5526 funtions in client to fully support pending command callbacks.
5528 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5529 as one of the arguments to the application in the command reply
5532 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5533 before first releasing SILC but came back. Now it is removed again
5534 and should come back nomore. The FORWARDED flag was used only
5535 by the JOINing procedure by forwarding the command packet to router.
5536 Now, the JOINing procedure has been changed to more generic (due
5537 to various router environment issues) and FORWARDED is not needed
5538 anymore for anything. The protocol specification is yet to be
5541 Now, removed silc_server_packet_forward from server and the flag
5542 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5544 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Renamed NAMES command to USERS command. The NAMES was named that
5547 due to historical reasons. Now it is renamed. Also, rewrote
5548 parts of the USERS command. The nickname list is not sent anymore
5549 by the server. Only Client ID and mode lists are sent in the USERS
5550 command. Changed this also to the protocol specification.
5552 The client now resolves the names and stuff after it receives
5553 the USERS list from the server when joining to the channel.
5555 * WHOIS and IDENTIFY commands has been changed to support multiple
5556 Client ID's per command. One can now search for multiple users
5557 in the network by sending only one WHOIS or IDENTIFY command.
5558 Changed the code and the protocol specifications.
5560 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5561 uses silc_server_command_whois_parse to parse the request. */
5563 * If normal server, do not parse the WHOIS and IDENTIFY requests
5564 before sending it to the router. Saves some time.
5566 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Fixed JOIN command on client library. Wrong number of arguments
5569 used to crash the client.
5571 * Added silc_server_channel_has_global function to check whether
5572 channel has global users or not.
5574 * Added silc_server_channel_has_local function to check whether channel
5575 has locally connected clients on the channel.
5577 * The silc_server_remove_from_one_channel now checks whether the
5578 channel has global users or not after given client was removed from
5579 the channel. It also checks whether the channel has local clients
5580 on the channel anymore. If it does not have then the channel entry
5581 is removed as it is not needed anymore.
5583 * The silc_server_notify now checks on JOIN notify whether the joining
5584 client is one of locally connected or global. If it is global then
5585 the channel has now global users on the channel and that is marked
5586 to the channel entry. Also, it now saves the global client to
5587 global list who is joining and JOINs it to the channel. This is
5588 for normal server, that is.
5590 Changed silc_server_send_notify_on_channel,
5591 silc_server_packet_relay_to_channel and
5592 silc_server_packet_send_to_channel check if we are normal server
5593 and client has router set (ie. global client) do not send the
5594 message to that client, as it is already routed to our router.
5596 * Implemented LEAVE notify type handling in silc_server_notify
5599 * Tested LEAVE command in router environment successfully. Tested
5600 with two routers, two servers and two clients.
5604 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5606 * Implemented SIGNOFF notify type handling in silc_server_notify
5609 * silc_server_remove_id now removes the client entry from all channels
5610 it has joined and thusly sends SIGNOFF notify type.
5612 * Rewrote the NAMES list generation in server by removing two excess
5613 loops. The lists are created now inside one loop.
5615 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5617 * silc_server_remove_channel_user checks now also global list
5618 for channel and client.
5620 * silc_server_new_channel_user checks now both local and global
5621 list for channel and client. Fixed a bug in client id decoding.
5622 Used to decode wrong buffer.
5624 * silc_server_channel_message checks now both local and global
5625 list for channel entry.
5627 * Tested channel joining (hence JOIN) in router environment
5628 successfully. Tested with two routers, two servers and two
5631 * Tested channel message sending in router environment successfully.
5633 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Added silc_server_save_channel_key into server.[ch] to save the
5636 received channel key in Channel Key payload processing. It is
5637 also used in JOIN command reply handling.
5639 Equivalent function silc_client_save_channel_key added into
5640 client.[ch] into client library.
5642 * Changed JOIN command reply to send information whether the channel
5643 was created or not (is existing already) and the channel key
5644 payload. Changed protocol specs accordingly.
5646 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5647 the request was sent by ID and not by nickname. Crashed on
5650 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5653 now correctly save the received data.
5655 * silc_server_free_sock_user_data now notifies routers in the
5656 network about entities leaving the network.
5658 At the same time implemented functions silc_server_remove_id
5659 and silc_server_send_remove_id to receive and send REMOVE_ID
5660 packets. The packet is used to notify routers in the network
5661 about leaving entities. The ID removed will become invalid in
5664 * Added function silc_idlist_del_server into server. Removes and
5665 free's server entry from ID list.
5667 * silc_server_private_message function now checks, if we are router,
5668 that the destination ID really is valid ID, naturally.
5670 * In router when NEW_ID packet is received (for new client) the
5671 hash of the Client ID is saved in the ID Cache but the
5672 client->nickname is set to NULL, instead of putting the hash
5675 IDENTIFY command now also checks that client->nickname must be
5676 valid. If it is not if will request the data from the server who
5677 owns the client. Added new function
5678 silc_server_command_identify_check.
5680 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5681 to set the command to already allocated Command Payload.
5683 * Tested private message sending in router environment with two
5684 routers, two servers and two clients. Fixed minor bugs and now
5687 * Fixed segfault from client's NAMES command. Used to crash if
5690 * Forwarded packets must not be routed even if it is not destined
5691 to the receiver. Changed server code comply with this.
5693 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Added `require_reverse_mapping' boolean value to ServerParams
5696 structure. If TRUE (not default) the server will require that
5697 the connecting host has fully qualified domain name.
5699 If the reverse mapping is not required and hostname could not be
5700 found the IP address is used as hostname.
5702 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Implemented version string checking to both client and server.
5705 The check is incomplete currently due to the abnormal version
5706 strings used in development version of SILC.
5708 * Changed all command functions in server to use the new
5711 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5713 * Changed char *data to unsigned char *data in ID Cache system to
5714 support binary data as ID Cache data. Changed code to support
5715 binary data in lib/silccore/idcache.c.
5717 * Renamed silc_server_packet_relay_command_reply to
5718 silc_server_command_reply as it is normal packet receiving
5719 function. Rewrote the function to accept command replys for
5720 servers and not only for clients.
5722 * Mark remote router always as registered server if we are connecting
5723 to it. Otherwise, commands sent by the router to us are ignored.
5725 * All ID List find routines now returns the ID Cache Entry pointer
5726 as well if requested.
5728 * WHOIS command works now in router environment, tested with two
5729 routers, two servers and two clients.
5731 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5732 in router environment (as it is almost equivalent to WHOIS) but
5733 hasn't been tested thoroughly. Added new functions:
5735 silc_server_command_identify_parse
5736 silc_server_command_identify_send_reply
5737 silc_server_command_identify_from_client
5738 silc_server_command_identify_from_server
5740 * Disabled route cache adding because adding two different ID's with
5741 same IP replaces the old cache entry thus giving wrong route.
5742 The entry->router->connection is always the fastest route anyway
5743 so route cache may not be needed. Of course, new routes maybe
5744 established after receiving the ID when the entry->router->connection
5745 might not be anymore the most optimal.
5747 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Add route cache for received ID for fast routing.
5751 * Added silc_server_packet_route to route received packet on router
5752 that is not destined to us.
5754 * Renamed silc_server_get_route to silc_server_route_get.
5756 * Added id_string and id_string_len fields into SilcServer to
5757 include encoded ServerID for fast comparing without excess
5758 encoding of the ID's.
5760 * Cleaned up WHOIS command on server side. Added following static
5763 silc_server_command_whois_parse
5764 silc_server_command_whois_check
5765 silc_server_command_whois_send_reply
5766 silc_server_command_whois_from_client
5767 silc_server_command_whois_from_server
5769 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5770 arguments in command replies. All command functions should be
5771 updated to use this macro.
5773 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Minor typo fixes on command reply handling on server.
5777 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * Added silc_server_command_add_to_channel internal routine to add
5780 the client to the channel after router has created the channel and
5781 sent command reply to the server.
5783 * Added generic silc_server_send_command to send any command from
5786 * Use static buffer with ID rendering instead of duplicating data.
5788 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Fixed a channel user mode bug when joining to a channel server gave
5791 everybody channel founder rights, oops.
5793 * We mark ourselves as the router of the incoming server connection
5794 if we are router ourselves. This way we can check in some packet
5795 sending functions whether it is locally connected server. For
5796 incoming router connections we put NULL.
5798 * For router sending packets locally means now always sending the
5799 packet cell wide; to local clients and local servers. For normal
5800 server sending packet locally means sending it to only local
5803 * Fixed the JOIN command to really work in router environment. If the
5804 channel is created it is always created by the router. Router is
5805 also responsible of making the initial joining to the channel,
5806 sending JOIN notify to the sending server and distributing
5807 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5808 does not exist server doesn't do anything else but forward the
5809 command to the router which performs everything.
5811 * Added silc_server_send_channel_key function to send the Channel Key
5814 * Added silc_server_create_channel_key to create new channel key. The
5815 channel key is now re-generated everytime someone joins or leaves
5816 a channel, as protocol dictates. Note: channel->key_len is the
5819 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5822 packet_receive.[ch] to separate packet sending and receiving
5823 routines. The server.[ch] now includes everything else including
5824 actual packet processing (writing and reading data) and other
5827 Renamed silc_server_private_message_send_internal to
5828 silc_server_send_private_message. The routine is still though
5829 used only to relay private messages as server does not send
5830 private messages itself.
5832 Renamed silc_server_new_channel to silc_server_create_new_channel
5833 and added new function sicl_server_new_channel that handles the
5834 incoming New Channel packet. Added also new sending function
5835 silc_server_send_new_channel to send New Channel Payload.
5837 * Added new function silc_server_notify to process incoming notify
5838 packet to the server/router. Server may then relay the notify
5839 to clients if needed.
5841 * Added new function silc_server_new_channel_user to process incoming
5842 New Channel User packet. Router will redistribute the packet and
5843 send JOIN notify to its local clients and locally connected servers
5844 if needed. Normal server will send JOIN notify to its local client
5845 on same channel when received this packet. Added also corresponding
5846 sending function silc_server_send_new_channel_user to sent the
5849 * Added boolean route argument to send_notif_to_channel and
5850 packet_send_to_channel functions to attempt to route the packet
5851 if it is TRUE and send only locally if it is FALSE.
5853 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * silc_server_replace_id now broadcasts the received replace ID
5856 packet if it is not broadcast packet already. The router must
5857 broadcast to inform other routers about changed ID.
5859 * Added backpointer to server's router into SilcServer context in
5860 silcd/server_internal.h.
5862 * Fixed silc_server_packet_broadcast to send correct broadcast
5865 * The channel key is now distributed to the local client as soon
5866 as it is received from the router (in router environment) so that
5867 no other packet may be sent for the channel until client has
5870 * silc_server_remove_channel_user now broadcasts the received
5871 Remove Channel User packet if it is not broadcast packet already.
5872 The router must broadcast to inform other routers about removed
5875 * Added users field into SilcPacketContext that is a reference count
5876 of the context. One can increase the reference count by calling
5877 silc_packet_context_dup which is now changed to just increase the
5878 reference count instead of duplicating the data. The reference
5879 count is decresed by calling silc_packet_context_free that will
5880 free the data after the reference count hits zero.
5882 For now on the packet context and everything allocated into it
5883 (including the raw packet from network) must be freed by calling
5884 the new silc_packet_context_free function. Added also new function
5885 silc_packet_context_alloc that must be used now to allocate the
5886 context. This also means that if a routine is asynchronous from
5887 silc_[client/server]_packet_parse_type the packet context must
5888 be duplicated by calling silc_packet_context_dup. Otherwise it
5889 gets free'd after silc_[client/server]_packet_parse_type returns.
5890 Also, one must remember that if packet is duplicated then its
5891 reference count must be decresed by calling the free function as
5892 many times as it was duplicated.
5894 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5895 from both client and server.
5897 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Made joining to a channel working in router environment.
5901 * Cleaned up JOIN command on server side and create function
5902 silc_server_command_join_channel internal routine to make the
5905 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5907 * Changed silc_command_pending list to SilcDList. Also, added
5908 `ident' field to SilcServerCommandPending structure to identify
5909 the reply and to call correct callback.
5911 Added silc_server_command_pending_check function to replace the
5912 corresnponding macro. The silc_command_pending list is not
5915 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5916 to set identifier to previously allocated Command Payload. It
5917 is used to set identifier for command when resending Command
5920 * Added silc_command_payload_encode_payload to encode Command
5921 Payload buffer from SilcCommandPayload structure.
5923 * Added silc_argument_payload_encode_payload to encode Argument
5924 payload buffer from SilcArgumentPayload structure.
5926 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5928 * Changed WHOIS command to support router connection on server side.
5929 The whois request is always sent to router unless the server is
5930 standalone server. After server has received the reply from the
5931 router will it send the reply to the client.
5933 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5934 broadcast received broadcast packet. The function is used only
5935 by router. The broadcast packet is always sent to the router's
5938 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5939 render given ID to printable string, for log files for example.
5941 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5943 * Made basic router to router connections working. At least they
5944 can now connect to each other but nothing really works the way
5945 they are supposed - yet.
5947 * Added new initiator token to RouterConnection configuration
5948 file in silcd/serverconfig.[ch]. It is used to tell whether we
5949 are the initiator to the remote router or whether we'll expect
5950 the other end to connect.
5952 * Moved registering of listener task to silc_server_init, hence
5953 the server starts listenning as soon as it is run, even if it
5954 does not have connections to other routers. Let's see how well
5957 * Changed default connection retry timeouts for more suitable in
5960 * Removed cipher and such arguments from silc_idlist_add_client
5961 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5962 Added new function silc_idlist_add_data to add the keys and stuff
5965 * Added SilcIDListData structure and added it to SilcClientEntry
5966 and SilcServerEntry as their first field in the structure. This
5967 way we can explicitly cast the ID entries to the SilcIDListData
5968 structure and get common data for the entries. In past, we had
5969 to first check what type of connection it is and then cast it to
5970 correct ID entry type. Now, we can directly cast the opaque
5971 pointer to the SilcIDListData (no matter what ID entry it actually
5972 is) and get the data needed.
5974 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5977 in some circumstances even if threre were timeout tasks, though not
5978 IO tasks, but tasks anyway. Now fixed.
5980 * Defined SilcServerConnection structure to hold connection specific
5981 stuff about directly connected servers and routers. The definition
5982 is currently in silcd/server_internal.h. I thought about having
5983 a bit more important role fro this struct but for now it is used
5984 only when connecting to other server (or router actually).
5986 * Added connecting retry support in server when connecting to
5987 router(s). The retry feature implement exponential backoff
5988 algorithm. Also, added SilcServerParams structure to hold default
5989 parameters for server. For now, it include these retry settings
5990 and are hard coded. After server is moded to be as Silc Server
5991 Library this structure will be more important.
5993 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Changed client librarys channel->clients table to SilcList and
5996 changed code accordingly.
5998 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6000 * Changed client's channel table to SilcList and changed code
6001 accordingly. Also changed SilcChannelClientEntry to include back-
6002 pointer to the channel so that client entry can use that structure
6003 as list as well and we have fast cross-reference to the channel.
6004 This change dramatically decreased the complexity of channel
6005 handling with client entry and vice versa (removed one extra
6006 loop when searching for channel entry from many functions).
6008 * Changed server->sim from table to SilcDList and changed code
6011 * NAMES command can now be used from user interface. It will show
6012 the user list on the channel, neatly.
6014 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6015 Code now saves realname of the user if it becomes available.
6017 * Renamed configure.in to configure.in.pre and made ./prepare
6018 script to automatically add correct version string to
6019 configure.in which it creates from configure.in.pre.
6021 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * NAMES command reply now shows users mode with the nickname when
6026 * Moved silc_client_ch[u]mode[_char] functions from
6027 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6028 place sucks, they are utility functions and should be in some
6031 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6033 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6036 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6040 * Added TRQ (efficient deque and list library) into lib/trq. This is
6041 a very good list library that is currently used in the SILC. Defined
6042 SilcList API over the library because I didn't like the API very
6043 much. See lib/trq/silclist.h for the API and examples of how to
6044 use the API. Fixed various places in the code to use the new
6045 SilcList API. The SilcList is meant for lists that has a structure
6046 already defined as a list. It is not suitable to add just some
6047 context to the list (in TRQ, the context is the list actually).
6049 So, I defined SilcDList that can be used for the purpose where
6050 predefined list structure does not exit. This can be used as
6051 such list. Now some context just can be added to the SilcDList.
6052 Currently this list is not used in the SILC just yet, though there
6053 are a lot places where this can replace dynamically allocated
6054 tables and I will fix these places, later, to use SilcDList.
6055 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6056 and use TRQ internally).
6058 Also fixed some annoying warning messages that the original TRQ
6059 code generated. Also minor changes to TRQ's Makefile.in.
6061 * Added support for querying by Client ID to both WHOIS and
6062 IDENTIFY commands into server, as required by the protocol.
6064 * Removed method function pointers from SilcBuffer structure. They
6065 weren't used to anything and just increased the context size for
6066 no good reason. This change also made silc_buffer_alloc and
6067 silc_buffer_free functions inline functions.
6069 * Disabled command flooding detection support until it's fixed so
6070 that it accepts commands in but does not execute them more than once
6073 * Added silc_net_localhost(), to return local hostname, into
6074 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6075 that must be initialized before calling silc_client_init.
6077 * Added new function: silc_server_send_notify_on_channels to send
6078 notify messages to all channels client has joined. It is assured
6079 that the message is sent only once per client.
6081 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6082 lib/silcutil/silcutil.[ch] as silc_format function. The new
6083 function is generic and is used by server as well, not only by
6084 the logging routines.
6086 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6087 the provided version string was not acceptable. Added new function:
6088 silc_ske_check_version into lib/silcske/silcske.h. The function
6089 must be implemented by the application (client or server) and it
6090 does not reside in the SKE library. The function checks the version
6091 string remote end sent.
6093 * Added back pointers (to opaque context and to SilcSocketConnection)
6094 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6096 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6097 duplicate packet context structure.
6099 * Changed `notify' client operation to send same arguments as client
6100 receives from server except for ID's. ID's are mapped to correct
6101 ID entry and that is returned. Also, if channel entry is not sent
6102 by server but the notify is for channel the channel entry is sent
6103 to application (otherwise application doesn't know that it is for
6104 channel (library gets it from packet's Destination ID)).
6106 * Added silc_client_remove_from_channels into client library to
6107 remove a client from all channels it has joined to. Used when
6108 received SIGNOFF notify from server. Added also new function
6109 silc_client_replace_from_channels to replace old ID entry with
6110 new ID entry on all channels. Used when received NICK_CHANGE
6113 * Fixed ID Cache list handling in silc_idlist_get_client in
6114 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6115 to get (or query) client by ID.
6117 * Updated TODO list.
6119 * Added connection authentication status message defined by the
6120 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6121 support for these into the code in client and server side.
6123 * Added generic function silc_client_send_command to send any command
6124 with variable argument list. Application should use this function
6125 to send commands if the command functions provided by the library
6126 does not suite for the application's user interface needs.
6128 * Added new `failure' client operation. Application is notified about
6129 received failure packet if client is executing a protocol. In this
6130 case the protocol's execution has failed.
6132 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6133 is required by the protocol.
6135 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6136 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6139 * Added status flag to SilcSKE object to indicate realtime status
6140 of the SKE protocol.
6142 * Application receives now exactly same command reply arguments as
6143 the library receives from server. However, if ID is received the
6144 corresponding ID entry is returned to the application (eg. Client
6145 ID is mapped to correct SilcClientEntry entry and that is returned).
6146 Changed command_reply client operation due to this change.
6148 * Changed all ID's in commands and in command replys as ID Payloads.
6149 Change affected both client and server side codes.
6151 All ID's sent in SILC network (with execption of ID's in SILC
6152 Packet header) are sent in ID Payload to support variable length
6155 * Server now notifies nick changes and notifies all clients on
6156 the channels about the new nickname (about the new Client ID,
6159 * Implemented CMODE command to change channel modes. Supports all
6160 channel modes defined by the protocol specs except ban and invite
6161 lists. (Also, private channel key mode is supported but support for
6162 setting private channel key in client is missing, thus, this mode
6163 has no effect on client side (except that server requires that the
6164 client uses private channel key and normal channel traffic does not
6167 Also, invite mode works per se, but INVITE command does not work
6168 yet correctly, so you can set channel as invite only channel but
6169 inviting clients to the channel does not work (it is yet to be
6170 thought what's the best way to do it).
6172 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6173 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6174 Implemented CUMODE command to change user's mode on the channel.
6175 Supports all modes defined by the protocol specs.
6177 * Added NAMES command reply to return users modes on the channel.
6179 * Removed unnecessary and slow ciphers from lib/silccrypt.
6181 * Set SO_KEEPALIVE option to connection sockets by default.
6183 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6185 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6186 redefined the Notify Payload into protocol specs.
6188 * Added silc_id_payload_parse_id to get ID directly from raw
6191 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6193 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6194 accept searching by Client ID as well.
6196 * Added support for LEAVE and SIGNOFF notify types in client library.
6198 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6199 to parse ID Payload from raw data.
6201 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * Added flags parameter into silc_ske_assemble_security_properties
6204 function in lib/silcske/silcske.[ch].
6206 * Changed notify client operation to fit better for notify messages
6207 sent by server. The notify payload received from server is now
6208 passed to the application (after parsing it to SilcNotifyPayload).
6209 It is application's responsibility to retrieve the arguments
6210 from the payload and show the message the way it wants. The message
6211 sent by server is implementation specific.
6213 * Changed public keys to comply with the protocol specification.
6214 Old public keys are not supported anymore and are not compatible.
6216 * Removed nickname from Channel Payload as the latest draft removed
6217 it. The client must resolve the nickname from the NAMES command
6218 reply received when it joined the channel.
6220 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6222 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6224 * Fixed some errors in protocol specification drafts.
6226 * Created lib/silccore/silcnotify.c to implement Notify Payload
6227 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6228 generic payloads described by protocol specifications. The file
6229 includes implementations for ID Payload and Argument Payload.
6231 * Changed Command Payload implementation to use the new Argument
6232 Payload. Changed command_xxxx_payload to command_payload_xxxx
6233 to comply with SILC coding conventions.
6235 * Added suppport for Argument Payload handling in Notify Payload
6236 implementation as protocol requires it. Added the new support
6237 into server and client lib as well.
6239 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6241 * Added support for multiple nicknames on same channel. [n] is
6242 added locally to the nickname if there are more than one same
6243 nicknames on the channel.
6245 * Server now sends all nicknames that matched WHOIS request.
6246 Client also shows the list received from server.
6248 * Added TOPIC command to client side. User can now set and show
6249 current topic on channel.
6251 * Added MOTD command to client and server. Also, server sends the
6252 motd when client connects to the server.
6254 * Changed version strings to comply ISO 8601.
6256 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6258 * Fixed protocol error handling in client library. It should now
6259 cope even if the SKE fails for some reason.
6261 * Made new protocol specification drafts for submitting to IETF.
6263 * Implemented TOPIC command to server in silcd/command.c.
6265 * Added two new notify types into lib/silccore/silcnotify.h:
6266 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6267 notify nickname change and topic setting/change on a channel.
6269 * API change of command_reply operation in client library. The
6270 application gets now the status type received from server as well.
6272 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6276 * Cras fixed and optimized the packet handling even further and
6277 it should work now. Minor change to the prototype of function
6278 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6280 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6282 * Added new function into lib/silcutil/silcschedule.[ch]:
6283 silc_schedule_with_fd to select() a specified fd. The function
6284 returns after timeout expires or data arrives or goes. The
6285 function is used by packet routines to wait that all data is
6286 received from network.
6288 * Fixed data reading from network in lib/silccore/silcpacket.c.
6289 The code now assures that all data is read from the fd and then
6290 continues packet processing. This was a bug fix since the code
6291 used to drop some data in some circumstances.
6293 * Added new function into lib/silcclient/client.[ch]:
6294 silc_client_start_key_exchange to start key exchange after
6295 connection has been established to server. The code internally
6296 now uses this funtion but its main purpose was to provide it
6297 for applications that perform their own connecting. After
6298 application has created a connection it merely calls this
6299 function to start the key exchange between client and server.
6300 The library takes care of everything else after that.
6302 Updated also lib/silcclient/README to explain the usage of
6305 * Do not send to application information that connection has
6306 been established. Application gets notified it by connect
6309 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6311 * Applied cras's patch to add silc_schedule_one function. The
6312 function runs scheduler once and returns.
6314 * Fixed the scheduler after cras messed it up. The timeout
6315 handling works now as it's supposed to work.
6317 * Added into lib/silccore/ silcnotify.h to include notify
6318 message types support. Changed silc_server_send_notify*
6319 functions, in server.[ch], to support those new notify types.
6320 Added the support for the notify types into client library,
6321 as well. Added new notify client operation into ops.h in
6324 * Changed silc_server_packet_send_to_channel to send normal
6325 packets instead of just channel message packets. The function
6326 is now used to send the notify packets to channels. It is not
6327 used to send channel message packets anymore, as server never
6330 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6331 va_arg()s as it seems to require it nowadays. I guess, if SILC
6332 is compiled with older va_arg() the new code should work anyway.
6334 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Splitted core library. Core library (lib/silccore) includes
6337 now only SILC protocol specific core (and common) components.
6338 Created new utility library (lib/silcutil) that includes more
6339 generic purpose stuff. The stuff for util library was taken
6340 from the old core library. This was minor and easy split.
6342 * Created SILC Client Library (lib/silcclient) that includes
6343 implementation of the SILC client without user interface. This
6344 was major move from silc/ directory. The code has been changed
6345 so that it is transparent towards the user interface. The
6346 silc/ directory includes now the same user interface as before
6347 and it uses the new client library. Read lib/silcclient/README.
6348 Basicly, the client library performs everything else related
6349 to SILC except user interface handling. Also, configuration
6350 files are considered to be part of user interface and library
6351 does not handle them.
6353 This change also changed a lot of structures, function naming etc.
6354 Most important change was that SilcClientWindow object was
6355 renamed to SilcClientConnection in the client library. Created
6356 also new file lib/silcclient/ops.h. Also added new files
6357 silc/local_command.[ch] and silc/client_ops.[ch].
6359 All these changes were made to make it easier for user interface
6360 designers to create what ever user interface for the SILC client
6363 It is also expected that the server will be moved to lib
6364 directory as well and SILC Server Library will be created;
6365 sometimes in the future.
6367 * Removed Local commands from lib/silccore/silccommand.h as
6368 they are application specific and new client library does not
6369 handle any of those anymore.
6371 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6372 old client implementation in silc/.
6374 * Added support for callback functions in SILC_LOG_* macros.
6375 Application can now set its own callbacks that will be called
6376 instead of using the default functions that will always print
6377 the debug messages to stderr (or stdout). Also, debugging can
6378 now be disabled by setting silc_debug to FALSE and re-enabled by
6379 setting it to TRUE. Note, that logging will still work even
6380 if debugging is disabled.
6382 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6383 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6384 silc_log_reset_debug_callbacks.
6386 * To enable debugging in silc client one must give now -d
6387 option on command line.
6389 * Changed silc_schedule_init to automatically allocate task queues
6390 if they are not allocated before calling it.
6392 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6394 * Added GMP 3.1 into math library.
6396 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6398 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6399 a channel in SILC network. The packet is used by servers and
6400 routers to notify other routers that user has left a channel.
6401 This little feature was missing until now. Added the feature
6402 to protocol specification as well.
6404 Added functions: silc_server_send_remove_channel_user and
6405 silc_server_remove_channel_user into server.[ch].
6407 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6408 lib/silccore/silcpacket.h. However, they are not implemented
6411 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6413 * Fixed joining to a channel and sending channel messages
6414 between server and router. The channel message sending should
6415 now work inside a cell.
6417 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6419 * Fixed the private message sending between server and router.
6420 The private message sending should now work inside a cell.
6422 * Added silc_server_replace_id into server.[ch] to replace
6423 existing ID in the SILC network.
6425 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6426 and silc_idlist_replace_server_id into idlist.[ch] in server.
6428 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Fixed the server to server connections. Server can again now
6431 connect to router. Router to router connections probably does
6434 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Added dynamic protocol registering support. Now protocols can
6437 registered and unregistered on the fly. Patch by cras.
6439 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Added lib/contrib directory to hold routines that some platforms
6442 don't have but are needed by SILC.
6444 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6445 into lin/contrib to provide getopt() and getopt_long() for
6446 those who don't have it.
6448 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6450 * Added AWAY command to client. When away message is set and
6451 client receives a private message packet the client automatically
6452 replies to the sender with the away message.
6454 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6455 bug seemed to be the cause of recent problems when compiling
6458 * Added version detection support to SKE protocol specification
6459 and added the new changes to the SKE implementation as well.
6460 There were other minor changes in the SKE protocol as well.
6462 Many changes in lib/silcske/silcske.[ch] and in
6463 lib/silcske/payload.[ch].
6465 * Added ^U functionality, clear input line. Patch from cras.
6467 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * Mainly small bugfixes on core library. Fixed some debugging
6470 logging and buffer overflow in silclog.c.
6472 * Updated config.sub and config.guess on the distribution tree.
6474 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Added command lagging support in server. Client may execute
6477 commands now only once in two seconds.
6479 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6481 * Optimized packet reception. MAC computation and checking is now
6482 also more optimized. A lot previously duplicated code is now
6483 used as generic by both client and server.
6485 * Fixed key pair generation in clientutil.c
6487 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6489 * Added into lib/silccore/silcbufutil.[ch] new function;
6490 silc_buffer_realloc.
6492 * Moved generic packet sending/encryption functions to
6493 lib/silccore/silcpacket.[ch] from client and server. Some
6494 rewriting of the functions.
6496 * Moved all generic packet reception/decryption functions to
6497 lib/silccore/silcpacket.[ch] from client and server. The
6498 packet processing is now much cleaner in both client and server.
6499 These were major changes in both client and server.
6501 * Created many common functions in server to do packet sending.
6502 Previously code were duplicated a lot, this has been removed
6505 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Rewrote major parts of the ID cache system. Don't know
6508 whether it is better now or not but at least the API is more
6511 * Major rewrite on ID cache stuff on client because of the ID
6512 cache API changes. Added idlist.c to client.
6514 * Also major rewrite on ID cache stuff on server as well.
6515 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6516 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6517 in hand, instead they are all put into the ID cache system now.
6518 All server_idlist_* routines uses ID cache now instead of
6519 traversing its own lists (those lists does not exist anymore).
6520 SilcIDList though still exists. Also, SilcXXXEntry's are
6523 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6525 * Finally made the SKE implementation compliant to the protocol
6526 specification. All mp integers are now binary encoded as
6527 opposed being HEX encoded.
6529 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6532 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6533 functions: silc_[encode/decode]_pem. Also added function
6534 silc_encode_pem_file to PEM encode with newlines ('\n') for
6537 * SILC public keys are now encoded either PEM or binary. Same
6538 option is for private keys as well. By default private keys
6539 are binary encoded and public keys PEM encoded. Silly HEX
6540 encoding were removed.
6542 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6543 function to create fingerprints.
6545 * Fixed a bug in SHA1; does not change the original data anymore.
6547 * Partly implemented INFO command on client and server side.
6548 Fixed CLEAR command. Changes to SERVER command; show current
6549 server(s) when giving command without arguments. Added
6550 VERSION command to client.
6552 * Added check to server that unregistered connections cannot
6553 execute commands (unless it is specificly allowed).
6555 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6557 * Fixed screen refresh.
6559 * Fixed channel joining bug from client. On some circumstances
6560 client tried to join to a channel it had already joined.
6562 * Added public key verification process into client's protocol.c.
6563 The client now verifies the public key from user and saves
6564 it into ~./silc/serverkeys/ directory.
6566 Added into: clientutil.[ch]: silc_client_verify_server_key.
6568 * Changed SKE protocol's silc_ske_initiator_finish function
6569 to accept callback function that verifies the received public
6570 key. Removed old silc_ske_verify_public_key function.
6572 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6575 silc_pkcs_private_key[_data]_set.
6577 * Made the password and public authentication more cleaner in
6578 server's protocol.c.
6580 * Removed historic and obsolete protocol `channel_auth' from
6581 both client and server.
6583 * Removed wrong way of sending command status messages from
6584 server to client in server's command.c. The old way violated
6585 protocol specification.
6587 Changes to silccore/silccommand.[ch]: removed
6588 silc_command_encode_status_payload -> not needed anymore,
6589 changed silc_command_encode_payload_va to accept extra
6590 argument on variable argument list. The argument type must
6591 now be provided to the function. Also, added new function:
6592 silc_command_encode_reply_payload_va which is same as
6593 normal command_encode_payload_va except command status type
6594 is provided as extra argument.
6596 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Added ~./silc directory handling. The directory includes the
6599 public and private keys for the client.
6601 Added silc_client_check_silc_dir, silc_client_create_identifier
6602 and silc_client_load_keys.
6604 * Implemented SILC protocol compliant public key. Added public
6605 and private key saving to and loading from files.
6607 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6608 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6609 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6610 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6611 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6613 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6614 silc_pkcs_load_[public/private]_key.
6616 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6618 * Added silc_server_get_route (route.[ch]) to get connection
6619 data for the fastest route for given ID.
6621 * Implemented INVITE command on client and server. The command
6622 were re-defined in the SILC Protocol Specification and the
6623 implementation now complies with the specification.
6625 * Implemented PING command on client and server.
6627 * Implemented NAMES command on client and server. The server side
6628 supports currently only normal server not router server yet.
6629 Some changes to NAMES definition in SILC protocol specification.
6631 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Implemented LEAVE command on client and server.
6635 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6636 again. This change was made to the protocol as well. Server
6637 should not violate the protocol specification anymore.
6639 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6641 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6642 was tested. SOCKS4 was not but should work anyway.
