3 * Do not save client history information in SERVER_SIGNOFF.
4 Fixes the bug in normal server that it does not detect
5 the client becoming valid after the server becomes back
6 online. Affected file silcd/server_util.c.
8 * Added `sock_error' field into the SilcSocketConnection
9 context. When error occurs during socket operation (read
10 or write) the error is saved. Added also new function
11 silc_socket_get_error to return human readable socket error
12 message. Affected files are lib/silcutil/silcsockconn.[ch],
13 lib/silcutil/unix/silcunixsockconn.c, and
14 lib/silcutil/win32/silcwin32sockconn.c.
16 * The server now prints the socket error message in the
17 signoff for client. Affected file silcd/server.c.
19 * Fixed the `created' channel information sending from router
20 to server in JOIN command. Checks now whether the channel
21 really was created or not and set it according that.
23 Fixed the JOIN command to use the client entry's current
24 ID during the joining procedure instead of the one it sent
25 in the command (it is checked though), since it can change
26 between the packet processing and command processing, and
27 would just case unnecessary pain in the client end. Affected
30 * Fixed a channel key payload sending to use correct channel
31 ID when the server was forced to change the channel's ID by
32 router. Router sent the key payload with the old Channel ID.
33 Affected file silcd/packet_receive.c.
35 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
37 * Call silc_server_save_channel_key only if the key payload
38 was provided in the JOIN command's command reply. Affected
39 file silcd/command_reply.c.
41 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
43 * Fixed silc_mp_sizeinbase to return the value correctly with
44 MPI. Affected file lib/silcmath/mp_mpi.c.
46 * Fixed the stop_server signal to correctly stop the scheduler
47 and gracefully stop the server when SIGTERM or SIGINT signals
48 are received. Affected file silcd/silcd.c.
50 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
52 * Simple handling of TERM and HUP signals. Also added some log
53 flushing call around. Affected file is
56 * Fixed small bugs in silclog.c. Now buffering output will take
57 effect after 10 seconds since startup: This will ensure that
58 no important startup messages are lost. Also output redirection
59 will preserve original format ([Date] [Type] message).
60 Affected file is lib/silcutil/silclog.c.
62 * Added two options to the config file, in the logging section:
63 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
64 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
66 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
68 * Do not print the warning about log files not being initialized
69 more than once to avoid excess logging. Affected file is
70 lib/silcutil/silclog.c.
72 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
73 the SIM copying in make install in Makefile.am.pre.
75 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
77 * Rewritten silclog APIs. Globally interesting changes follows:
78 silc_log_set_files() changed to silc_log_set_file().
79 silc_log_set_callbacks() changed to silc_log_set_callback().
80 ROBOdoc documented silclog header file.
81 SilcLogCb now returns bool to wether inihibit the default
82 handler or not (to keep the old behaviour return always TRUE).
83 The new APIs should also fix the problem of the
84 silcd_error.log file that was written in the current directory.
87 Log files streams will remain opened after silc_log_set_file()
88 call, means less CPU usage notably on high traffic servers.
89 File streams are now full buffered, and flushed to the disk
90 every 5 minutes, lesses HD activity and CPU usage.
91 Messages can be redirected, allowing admins to configure
92 one single logfile for all server messages.
93 the silc_log_quick global variable to activate fast-logging.
94 Affected files lib/silcutil/silclog.[ch]
96 * Changed some code to conform new silclog APIs. Affected
97 files are doc/example_silcd.conf.in, silcd/server.c
98 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
101 * Fixed a memory leak that could occur in some situations.
102 Affected file silcd/serverconfig.c.
104 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
106 * Added the silc_client_del_client to remove the client from
107 all channels as well. Affected file lib/silcclient/idlist.c.
109 * Fixed the client library to correctly remove the client
110 from all channels when the client entry is being destroyed.
111 Affected file lib/silcclient/client_notify.c, command.c.
113 * Added auto-nicking support to the client library. If the
114 applicatio now sets client->nickname it will be sent to the
115 server after connecting by the library. This way for example
116 SILCNICK (or IRCNICK) environment variables will have effect
117 and always change the nickname automatically to whatever
118 it is wanted. Affected file lib/silcclient/client.[ch].
120 * Renamed silc_server_command_bad_chars to the
121 silc_server_name_bad_chars and moved it to the
122 silcd/server_util.[ch]. Added also new function
123 silc_server_name_modify_bad to return nickname that
124 includes bad characters as new nickname without those
125 bad characters. This check and modify is now used in
126 silc_server_new_client when the username is initially set
127 as nickname, so it must be checked to be valid nickname.
128 Affected file silcd/packet_receive.c.
130 * The nickname length is now taken from the packet for real
131 and not trusted to strlen() since it clearly can return
132 wrong length for nickname including bad characters. This
133 also applies to channel names. Affected file silcd/command.c.
135 * Removed the lib/silcsilm/modules directory. Modules are now
136 compiled into the lib/silcsim. Fixed the copying of the
137 modules to follow symbolic links in Makefile.am.pre.
139 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
141 * Fixed silc_string_regexify list creation. Fixes bugs with
142 BAN and INVITE commands in server. The affected file is
143 lib/silcutil/unix/silcunixutil.c.
145 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
147 * Removed the command destructor entirely from the server's
148 command and command reply routines. It is not needed, and
149 its usage was buggy and caused crashes. Affected files are
150 silcd/command[_reply].[ch].
152 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
154 * Cancel protocol and NULL sock->protocol if timeout
155 occurred during protocol. Affected file silcd/server.c.
157 * Cancel protocol timeouts always before calling the final
158 callback, to assure that after final callback is called
159 no other state will be called for the protocol anymore.
160 Affected file silcd/protocol.c.
162 * Print error log if incoming connection configuration could
163 not be found. Affected file silcd/server.c.
165 * Fixed JOIN command to correctly save the founder mode
166 to the client on normal SILC server, when the channel
167 was created by the router. Affected file silcd/command.c.
169 * Fixed LIST command (hopefully) to send correct reply
170 packets. Affected file silcd/command.c.
172 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
174 * The silc_packet_receive_process now returns FALSE if the
175 read data was invalid packet, and TRUE if it was ok.
177 The server now checks that if unauthenticated connection
178 sends data and its processing fails the server will close
179 the connection since it could be a malicious flooder.
181 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
183 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
185 * Make sure the warning about error opening a log file is
186 printed only once and not everytime it fails (produces
187 too much useless log). Affected file lib/silcutil/silclog.c.
189 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
191 * Made the silc_server_daemonise() function more readable.
192 Affected file silcd/server.c.
194 * Pid file is now optional, the user may comment it out from
195 the config file. Removed define SILC_SERVER_PID_FILE, we
196 don't need a default any longer. Affected file
197 configure.in.pre, lib/Makefile.am.pre.
199 * Make some use of the pid file. The server now dies at startup
200 if it detects a valid pid file on his path. The server would
201 die anyway in this circumstance, because of the bind() failure.
202 Affected file silcd/silcd.c.
204 * No longer compiling lib/dotconf.
206 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
208 * Fixed JOIN command parsing not to crash. Affected file
209 lib/silcclient/command.c.
211 * Fied the NICK_CHANGE notify to add the new client entry
212 even it is resolved. This removes an <[unknown]> nick
213 thingy bug in the client. Affected file is
214 lib/silcclient/client_notify.c.
216 * Do not try to allocate 0 bytes (efence does not like it)
217 in lib/silccore/silccomand.c when encoding payload.
219 * Do not take IRCNICK as nickname in Irssi SILC client since
220 it is not possible to set nickname before hand connecting
221 the server (TODO has an entry about adding auto-nicking
224 * Changed the silc_server_command_pending to check whether
225 there already exists an pending entry with the specified
226 command, command identifier and pending callback. This is
227 to fix IDENTIFY and WHOIS related crashes that may register
228 multiple pending commands with same identifier. Affected
229 file silcd/command.c.
231 * Fixed the server to reconnect to the router even if it
232 was already reconnecting and EOF was received. This to
233 fix a possibility that the server wouldn't ever try to
234 auto-reconnect to the router. Affected file silcd/server.c.
236 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
238 * Fixed the server's password authentication to use the
239 length of the locally saved password, and not the one
240 sent in the packet. Affected file silcd/protocol.c.
242 * Fixed same password authentication problem in the
243 Authentication Payload handling routines in
244 lib/silccore/silcauth.c.
246 * Yet another password authentication problem fixed with
247 channel password handling in silcd/command.c.
249 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
251 * If first character of string in silc_parse_userfqdn is '@'
252 then do not parse it. Affected file is
253 lib/silcutil/silcutil.c.
255 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
257 * Fixed minor bug in IDENTIFY command reply sending, which
258 caused various weird problems during JOIN when it was
259 resolving names for users. Affected file silcd/command.c.
261 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
263 * Fixed the IDENTIFY command reply sending to chech better valid
264 clients. It was possible to send incomplete list of replies.
265 Affected file silcd/command.c.
267 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
269 * Added silc_client_command[s]_[un]register functions now to
270 dynamically register the commands in client library. Removed
271 the static table of commands. This allows the client library
272 to call commands without causing the application to know about
273 what commands library has called.
275 Removed the INFO command reply kludge to detect when the command
276 was called by library. Now library use its own command reply
277 function for INFO command.
279 Added function silc_client_command_call to call a command.
280 Application can use it to call command, not access the structure
283 Now all commands that are sent by the client library (not
284 explicitly sent by application) use own command reply functions.
286 Affected files around lib/silcclient/ and in
287 irssi/src/silc/core/.
289 * Fixed the WHOIS command reply sending to chech better valid
290 clients. It was possible to send incomplete list of replies.
292 Fixed the WHOIS and IDENTIFY to send the request to router
293 if normal server did not do it and did not find any results.
295 Affected file silcd/command.c.
297 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
299 * Moved the internal data from SilcClient context into its
300 own file, not accesible to application. Affected files
301 lib/silcclient/client.h and lib/silcclient/client_internal.h,
302 and other files in client library.
304 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
306 * Added doc/examples installation target in Makefile.am.pre.
309 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
311 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
312 commands the found client entry will be removed from the
313 cache, after notifying application about the error. Affected
314 file lib/silcclient/command_reply.c.
316 * Changed the /MSG to check for exact nickname user gave, and
317 not let `nick' match `nick@host' if it is only one found. Now,
318 user must type the exact nickname (like nick@host2) even if
319 there are no more than one same nicks found. This is to avoid
320 a possibility of sending nickname to wrong nickname since
321 `nick' could match `nick@host'. Affected file is
322 irssi/src/core/silc-servers.c.
324 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
326 * Do not print "you are now server operator" or similar when
327 giving /away command. Affected files are
328 irssi/src/silc/core/client_ops.c, silc-servers.h.
330 * Made the silc_server_command_pending_error_check to send
331 the same command reply payload it received back to the
332 original sender of the command. This way all arguments
333 that was received by the server will be received by the
334 client too. Affected file silcd/command.c.
336 * Added the silc_idcache_add to return the created cache entry
337 to a pointer. Affected file lib/silccore/silcidcache.[ch].
339 * Add global clients to expire if they are not on any channel.
340 This is because normal server will never know if they signoff
341 if they are not on any channel. The cache expiry will take
342 case of these entries. This is done by normal servers only.
343 The affected files are silcd/command_reply.c,
344 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
346 * If server receives invalid ID notification for WHOIS or
347 IDENTIFY and the ID exists in the lists, it is removed.
348 Affected file silcd/command_reply.c.
350 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
351 in client then client entry that it matches is searched and
352 the nickname is printed on the screen for user. Affected
353 file irssi/src/silc/core/client_ops.c.
355 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
357 * Use cache entry expire time in the LIST command reply to
358 purge old entries from the cache after the LIST command
359 reply has been received. This way we don't have non-existent
360 entries in the cache for too long. Affected file is
361 silcd/command_reply.c.
363 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
365 * If we are normal server, and we've not resolved client info
366 in WHOIS or IDENTIFY from router, and it is global client,
367 we'll check whether it is on some channel. If it is not
368 then we cannot be sure about its validity and will resolve it
369 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
370 file silcd/command.c.
372 * Search channel by name (if possible) rather than by ID
373 in IDENTIFY command's command reply. Affected file is
374 silcd/command_reply.c.
376 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
378 * Distribute to the channel passphrase in CMODE_CHANGE notify.
379 Updated specs and implemented it. Affected file silcd/command.c,
380 silcd/packet_send.c and silcd/packet_receive.c.
382 * Implemented the <founder auth> payload handling in the JOIN
383 command. If provided all conditions for channel joining
384 except requirement to provide correct passphrase can be
385 overrided by the channel founder. Updated the protocol specs.
386 Affected file silcd/command.c.
388 Added support for founder auth in JOIN command in client
389 library. Fixed the parsing of the JOIN command now to support
390 all options as they should be. The affected file is
391 lib/silcclient/command.c.
393 * Optimized the WHOIS and IDENTIFY commands to send the request
394 to router only if it includes nicknames or other names. If
395 they include only IDs then check the local cache first before
396 routing. Affected file is silcd/command.c.
398 * Added channels topic announcements. Affected file is
399 silcd/packet_receive.c and silcd/server.c.
401 * Fixed the silc_server_send_notify_topic_set to really destine
402 the packet to channel. Affected file silcd/packet_send.c.
404 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
405 library. Affected file lib/silcclient/client_notify.c.
407 * Added UMODE announcements. Affected file silcd/server.c.
409 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
411 * Memory leak fixes in:
413 lib/silcutil/silcsockconn.c
414 lib/silcske/silcske.c
417 lib/silccrypt/silcpkcs.c
418 lib/silccore/silccommand.c
419 lib/silccore/silcidcache.c
424 * ROBOdoc documented the lib/silcske/groups.h file and a
425 bit changed the interface for better.
427 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
429 * Update the client entry context in the ID cache after
430 nick change. Affected file lib/silcclient/command.c.
431 Fixes the CUMODE command when regaining founder privileges,
432 and a little WHOIS problem.
434 * Fixed silc_net_gethostbyname to correctly call the
435 inet_ntop. Affected file lib/silcutil/silcnet.c.
437 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
439 * Added IPv6 support checking to the configure.in.pre, added
440 also --enable-ipv6 option to override the check. Affected
441 file configure.in.pre.
443 * The silc_thread_create now calls the start function
444 directly if threads support is not compiled in. Removes
445 ugly #ifdef's from generic code. Affected files are
446 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
448 * Added silc_net_gethostby[name/addr]_async to asynchronously
449 resolve. Affected files are lib/silcutil/silcnet.[ch].
451 * Added support for rendering IPv6 based server, client and
452 channel IDs. Affected file lib/silcutil/silcutil.c.
454 * Added support for creating IPv6 based server IDs. Affected
455 file is silcd/serverid.c.
457 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
459 * Added silc_net_gethostby[addr/name] into the
460 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
461 routines. Added silc_net_is_ip[4/6]. Affected file is
462 lib/silcutil/unix/silcunixnet.c. All routines that take
463 address as argument now supports both IPv4 and IPv6 addresses.
465 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
467 * Fixed LIST command reply sending in server. Affected file
470 * Server now sends the kicker's client ID in the KICK notify
471 to the kicked client. Affected file silcd/command.c.
473 * The client library now parses the kickers client ID and
474 UI displays it. Affected files lib/silcclient/client_notify.c
475 and irssi/src/silc/core/silc-channels.c, module-formats.c.
477 * Made all payload parsing function prototypes consistent.
478 They all take now const unsigned char * and uint32 pair as
479 the payload data instead of SilcBuffer. Changes all around
480 the source tree. Other unsigned char* -> const unsigned char*
481 changes around the tree as well.
483 * Optimized SFTP client and server packet sending not to
484 allocate new buffer for each packet but to recycle the
485 first allocated buffer. Affected files are
486 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
488 * Optimized the SFTP client to use SilcList instead of
489 SilcDList for requests, because it is faster. Affected file
490 is lib/silcsftp/sftp_client.c.
492 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
493 into lib/silccore/silcid.[ch].
495 Renamed silcpayload.[ch] into silcargument.[ch].
497 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
499 * If client entry is deleted with active key agreement
500 session, abort the session.
502 The silc_client_abort_key_agreement now calls the completion
503 callback with new SILC_KEY_AGREEMENT_ABORTED status.
505 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
508 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
510 * Don't use __restrict in older GCC's. Affected file is
511 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
513 * silc_net_localhost now attempts to reverse lookup the
514 IP/hostname. Affected file lib/silcutil/silcnet.c.
516 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
517 command. It can be used to gain founder privileges at
518 the same time when joining the channel.
520 Defined that the SILC_NOTIFY_TYPE_KICKED send the
521 kicker's client ID as well. Updated protocol specs.
523 Defined that the server must send SILC_COMMAND_IDENTIFY
524 command reply with error status to client who sent
525 private message with invalid client ID.
527 Updated the protocol specification.
529 * Added silc_server_send_command_reply to send any
530 command reply. Affected file silcd/packet_send.[ch].
532 * Added silc_id_payload_encode_data to encode ID payload
533 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
535 * The server now send IDENTIFY command reply with error
536 status if client ID in private message is invalid. Affected
537 file silcd/packet_receive.c.
539 * Save the server key file with server's IP address in
540 the filename instead of hostname. The affected file is
541 irssi/src/silc/core/client_ops.c.
543 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
545 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
548 * Added libtool support for compiling shared objects in
549 lib/silcsim. Affected file configure.in.pre and
550 lib/silcsim/Makefile.am. Original patch by cras.
552 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
554 * Pid file configuration, and server's config file fixes
555 patch by toma. Updated CREDITS file.
557 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
559 * Fixed silc_client_channel_message to not try to decrypt
560 the message twice if it resolved the destination client
561 information. This could cause of dropping one channel
562 message. Affected file lib/silcclient/client_channel.c.
564 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
566 * Added silc_client_run_one into lib/silcclient/silcapi.h and
567 lib/silcclient/client.c. This function is used when the SILC
568 Client is run under some other scheduler, or event loop or
569 main loop. On GUI applications, for example this may be
570 desired to used to run the client under the GUI application's
571 main loop. Typically the GUI application would register an
572 idle task that calls this function multiple times in a second
573 to quickly process the SILC specific data.
575 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
577 * Fixed silc_server_drop() for dropping the supplementary
578 groups as well, this could cause a security hole on some
581 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
583 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
586 * Write PID file after dropping privileges. Added -F option
587 to run server on foreground. A patch by debolaz.
588 Affected files silcd/server.c, silcd/silcd.c.
590 * Fixed MOTD to return the MOTD file server name. Affected
591 file silcd/command.c.
593 * Added INFO command reply handling to the Irssi SILC Client.
594 Affected file irssi/src/silc/core/client_ops.c.
596 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
598 * Fixed the silc_idcache_list_* routines to really support
599 the dynamic list. Fixes a crash. Affected file is
600 lib/silccore/silcidcache.c.
602 * Fixed the LIST command reply to really call LIST command's
603 pending callbacks. Affected file silcd/command_reply.c.
605 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
607 * Update conn->local_entry->nickname after giving NICK
608 command. Affected file lib/silcclient/command.c.
610 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
612 * Added the [pid] option to the silcd configuration file
614 Affected files: serverconfig.[ch] and silcd.c
616 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
618 * Save fingerprint in WHOIS command reply in server.
619 Affected file silcd/command_reply.c.
621 * Fixed NICK commands pending callback registration.
622 Affected file lib/silcclient/command.c.
624 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
626 * Use ++server->cmd_ident when sending commands in server,
627 instead of random number. Affected file silcd/command.c.
629 * Fixed GETKEY command reply to call actually GETKEY pending
630 command callbacks. Affected file silcd/command_reply.c.
632 * A bit stricter check for nicknames. Check for same nickname
633 in NICK command also. Affected file silcd/command.c.
635 * Do not call INFO command everytime client ID changes, only
636 during first connecting. Affected file lib/silcclient/client.c.
638 * Set the new nickname only after successful command reply for
639 NICK command is returned by server. Affected file
640 lib/silcclient/command.c.
642 * Remove nicknames from nicklist during server_signoff notify.
643 Should fix /NAMES bit more. The affected file is
644 irssi/src/silc/core/silc-channels.c.
646 * Added `fingerprint' field to the SilcIDListData in the
647 silcd/idlist.h to hold the fingerprint of the client's
650 Send the fingerprint of the client's public key in WHOIS
653 Affected files silcd/command.c, and silcd/idlist.[ch].
655 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
656 create fingerprint from given data.
658 * Show the fingerprint of the client's public key in WHOIS.
659 Affected files irssi/src/module-formats.[ch] and
660 irssi/src/silc/core/client_ops.c.
662 * Format the multiple same nicknames also during JOIN and
663 NICK_CHANGE notifys. Affected file is
664 lib/silcclient/client_notify.c.
666 * Do not print error on screen for invalid private message
667 payload since it can come if someone is sending private
668 messages with wrong key. Affected file
669 lib/silccore/silcprivate.c.
671 * Fixed multiple concurrent /PING crash. Affected file
672 lib/silcclient/command.c.
674 * Changed the wrong ID encoding. All IP addresses must be
675 in MSB first order in encoded format. They were encoded
676 wrong and was in LSB format. Affected files are
677 silcd/serverid.c, lib/silcutil/silcutil.c.
679 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
681 * Call the `connect' client operation through the scheduler
682 in case of error. Affected file lib/silcclient/client.c.
684 * Call the `failure' client operation even if the error
685 occurred locally during a protocol. Affected file is
686 lib/silcclient/protocol.c.
688 * Added support of sending LIST command to router from normal
689 server. This way normal server can get list of all channels
690 in the network too. Fixed the channel list sending in the
691 server too. Affected files are silcd/command.c, and
692 silcd/command_reply.[ch].
694 * Added silc_server_update_channels_by_server and
695 silc_server_remove_channels_by_server. They are used during
696 disconnection of primary router and in backup router protocol.
697 Affected file silcd/server_util.[ch], silcd/server.c and
698 silcd/server_backup.c.
700 * Fixed channel adding to global list in IDENTIFY command
701 reply in server. Affected file silcd/command_reply.c.
703 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
705 * If the incoming packet type is REKEY or REKEY_DONE process
706 that packet always synchronously. Fixes yet another MAC
707 failed error on slow (dialup) connections. Affected file
708 lib/silcclient/client.c and silcd/server.c.
710 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
712 * Call check_version SKE callback for initiator too. Affected
713 file lib/silcske/silcske.c.
715 * Implemented fix for security hole found in the SKE that was
716 fixed in the specification few days back; the initiator's
717 public key is now added to the HASH value computation.
718 Added backwards support for the old way of doing it too, for
719 old clients and old servers. Affected file is
720 lib/silcske/silcske.c.
722 * Enabled mutual authentication by default in SKE. If initiator
723 is not providing mutual authentication the responder will
724 force it. This will provide the proof of posession of the
725 private key for responder. The affected files are
726 lib/silcclient/protocol.c and silcd/protocol.c.
728 * Do not cache anymore the server's public key during SKE.
729 We do mutual authentication so the proof of posession of
730 private key is done, and if the server is authenticated in
731 conn auth protocol with public key we must have the public
732 key already. Affected file silcd/protocol.c.
734 * Added new global debug variable: silc_debug_hexdump. If
735 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
736 file lib/silcutil/silclog.[ch].
738 * Fixed compilation warning due to char * -> const char *.
739 Affected files lib/silcutil/silcnet.h, and
740 lib/silccore/silcauth.[ch].
742 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
744 * Fixed CMODE command when new channel key was created. If
745 the creation failed the old key was removed. Next time giving
746 same command would crash the server since the old key was
747 freed already. Affected file silcd/command.c.
749 * Fixed the silc_server_announce_get_channels to not crash
750 on reconnect. Affected file silcd/server.c.
752 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
754 * Added silc_log_set_debug_string function to set a regex
755 string to match for debug output. Only the function names,
756 or filenames matching the given debug string is actually
757 printed. This way it is possible to filter out those debug
758 strings that user is not interested in.
760 Fixed a bug in silc_string_regexify.
762 Affected files lib/silcutil/silclog.[ch], and
763 lib/silcutil/unix/silcunixutil.c.
765 * Changed the -d options in both server and Irssi SILC client
766 to take the debug string as argument. Affected files
767 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
769 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
771 * Added silc_hash_babbleprint to create a Bubble Babble
772 Encoded fingerprint. The encoding is developed by Antti
773 Huima (draft-huima-babble-01.txt), and it creates human
774 readable strings out of binary data. Affected file
775 lib/silccrypt/silchash.[ch].
777 * Print the babble print now in addition of fingerprint as well
778 in Irssi SILC client. Affected files are
779 irssi/src/fe-common/silc/module-formats.[ch],
780 irssi/src/fe-common/silc/core/client_ops.c.
782 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
784 * Fixed a security problem found in SKE. The initiator's
785 public key too is now added to the HASH hash value creation
786 which is signed by the responder to create the SIGN value.
787 This will prevent anyone in the middle to lie to the responder
788 about the initiator's public key. If this is done now, the
789 man in the middle will get caught. Updated the protocol
792 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
794 * Better installation directory handling. Configure module
795 paths and other paths automatically to example_silc* files
796 in doc/. A patch by toma.
798 * Fixed compiler warning from MPI library, and from SILC RNG.
801 * Added SILC_SERVER_PID_FILE to define the pid file for server.
802 It can be configured with ./configure. A patch by toma.
804 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
806 * Find correct make to use in prepare-clean. A patch by
807 toma. Affected file prepare-clean.
809 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
811 * Added irssi variables use_auto_addr, auto_bind_ip,
812 auto_bind_port and auto_public_ip.
814 * Changed the interface for silc_client_send_key_agreement
815 in lib/silcclient/silcapi.h
819 irssi/src/silc/core/silc-core.c
821 lib/silcclient/silcapi.h
822 irssi/src/silc/core/silc-channels.c
823 lib/silcclient/client_keyagr.c
826 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
828 * Added silc_pkcs_public_key_compare to compare two
829 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
831 * Check that the client who set the founder mode on the
832 channel is the same client that is giving the founder
833 mode to itself. It is done by comparing the saved public
834 key (it is saved even in the authentication is passphrase).
835 Affected file silcd/command.c.
837 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
839 * Do not process packet for disconnected socket connection.
840 Affected file lib/silccore/silcpacket.c.
842 * Process the DISCONNECT packet through scheduler in the
843 client library. Affected file lib/silcclient/client.c.
845 * Fixed the silc_client_packet_parse to not to increase
846 the packet sequence number if the conn->sock and the
847 current socket connection is not same. This can happen
848 for example during key agreement when the conn includes
849 multiple socket connections (listeners). Affected file
850 lib/silcclient/client.c.
852 * The sender of the file transfer request now provides also
853 the pointer (listener) for the key exchange protocol. If
854 the listener cannot be created then it sends empty key
855 agreement and lets the receiver provide the listener.
857 Added `local_ip' and `local_port' arguments to the
858 silc_client_file_send. If they are provided they are used,
859 if not then it will attempt to find local IP address, if
860 not found or bind fails then the remote client will provide
863 Affected files are lib/silcclient/client_ftp.c and
864 lib/silcclient/silcapi.h.
866 * Extended the FILE SEND command to support defining the
867 local IP and port for key exchange listener. They are
868 optional. Affected file irssi/src/silc/core/silc-servers.c.
870 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
872 * Defined to WHOIS command reply the sending of fingerprint
873 of the client's public key (if the proof of posession of the
874 corresponding private key is verified by the server).
875 Updated to the protocol specification.
877 * Added support of receiving the client's public key's
878 fingerprint in command reply in client library. Affected
879 file is lib/silcclient/command_reply.c, and
880 lib/silcclient/idlist.[ch].
882 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
884 * Do not send over 128 chars long nickname to the server
885 in NICK command. Affected file lib/silcclient/command.c.
887 * Do not send over 256 chars long channel names to the server
888 in JOIN command. Affected file lib/silcclient/command.c.
890 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
892 * Assure that silc_server_close_connection cannot be called
893 twice for same socket context. Affected file is
896 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
898 * Send error message to application if opening file for
899 writing during file transfer fails. Affected file is
900 lib/silcclient/client_ftp.c.
902 Remove all file transfer sessions for a client that we're
903 removing from ID cache.
905 Affected file is lib/silcclient/client_ftp.c.
907 * Fixed silc_net_addr2bin to return correct address. Affected
908 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
910 * Fixed file transfer session removing on signoff notify.
911 Affected file irssi/src/silc/core/silc-servers.c.
913 * Added the SilcClientFileError to be returned in the monitor
914 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
915 Affected file lib/silcclient/silcapi.h.
917 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
919 * Fixed a crash in silc_client_ftp_free_sessions and
920 silc_client_ftp_session_free_client. Affected file
921 lib/silcclient/client_ftp.c.
923 * Added `disabled' field in the SilcChannelEntry in the server
924 to indicate if the server entry is disabled. Affected file
925 silcd/idlist.h, silcd/command[_reply].c.
927 * SILC server adds now /var/run/silcd.pid everytime it is
928 started. Affected file silcd/silcd.c.
930 * Added silc_server_packet_send_clients to send a packet to
931 the provided table of client entries. Affected file
932 silcd/packet_send.[ch].
934 * Fixed a crash in client resolving in client_prvmsg.c in
935 client library. Affected file lib/silcclient/client_prvmsg.c.
937 * Do not actually remove the client directly from ID cache
938 during SERVER_SIGNOFF, but invalidate it. This way we
939 preserve the WHOWAS info for the client. Affected file
942 * Fixed SERVER_SIGNOFF notify handling in the server. The
943 server is now able to process incoming SERVER_SIGNOFF notify
944 for a server that it doesn't even know about. It will remove
945 the clients provided in the notify. Affected file
946 silcd/packet_receive.c.
948 * Check for partial packet in data queue after every packet that
949 was found from the queue. Return and wait for more data if
950 there is partial data in queue. Affected file is
951 lib/silccore/silcpacket.c.
953 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
955 * Added SilcClietFileError enum to indicate error in
956 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

961 * Check that newsize in silc_buffer_realloc is larger than
962 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
964 * Added better monitor of file transfers. It now monitors
965 key agreement protocol during the file transfer too. Added
966 error reporting too. Affected files
967 irssi/src/silc/core/silc-servers.c,
968 irssi/src/fe-common/silc/module-formats.[ch].
970 * Wrote a help file for FILE command.
972 * Added silc_rng_global_get_byte_fast to get not-so-secure
973 random data as fast as possible. Random data is read from
974 /dev/urandom if available and from the SILC RNG if not
975 available. It is used in padding generation. Affected file
976 lib/silccrypt/silcrng.[ch].
978 * All packets in client library are now processed synchronously.
979 Optimized packet processing a lot. Affected file
980 lib/silcclient/client.c.
982 * All server connection packets are processing synchronously
983 now in server, to optimize packet processing. Affected file
986 * Include files are installed now only in Toolkit distribution
987 if make install is given. Affected files: all Makefile.am's.
989 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
991 * Assure that silc_client_notify_by_server_resolve does not
992 resolve the client information multiple times. If it cannot
993 be found by the first it cannot be found at all. Affected
994 file lib/silcclient/client_notify.c.
996 * Fixed WHOWAS command reply calling. Affected file
997 lib/silcclient/command_reply.c.
999 * Removed all references to silc_idlist_get_client from the
1000 Irssi SILC client since that call is internal call used by
1001 the library. The Irssi SILC client will use now client
1002 retrieval functions found in silcapi.h.
1004 * Fixed a bug in resolving nickname info before sending
1005 private message. It used freed memory. Affected file
1006 irssi/src/silc/core/silc-servers.c.
1008 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1010 * Assure my_channels statistics cannot go negative in server.
1011 Affected files silcd/server.c, silcd/server_util.c.
1013 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1023 lib/sftp/sftp_fs_memory.c.
1025 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1027 * Added silc_net_localip to return local host's IP address.
1028 Affected file lib/silcutil/silcnet.[ch].
1030 * If key exchange or rekey protocol is active for a connection
1031 parse all packets syncronously since there might be packets
1032 in packet queue that we are not able to process without first
1033 processing packets before them. Affected file silcd/server,
1034 lib/silcclient/client.c.
1036 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1037 whether library should continue processing the packet.
1038 Affected file lib/silccore/silcpacket.h.
1040 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1041 SilcSFTPMonitorData to SFTP server to monitor various
1042 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

1049 Added preliminary support for simple client to client one-file
1050 transmission. Affected file lib/silcclient/client_ftp.c,
1051 lib/silccilent/client.[ch].
1053 * Added new local command FILE to the Irssi SILC Client.
1054 It is used to perform the file transfer. It has subcommands
1055 SEND, RECEIVE, SHOW and CLOSE. Affected files
1056 irssi/src/silc/core/client_ops.c,
1057 irssi/src/silc/core/silc-server.[ch].

1069 lib/silcutil/silcutil.[ch].
1071 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1073 * Resolve the client info when received private message or
1074 channel message for a client which nickname we don't know.
1075 Affected files lib/silcclient/client_prvmsg.c and
1076 lib/silcclient/client_channel.c.
1078 * Do not crash in /KEY if client is not connected. Affected
1079 file irssi/src/silc/core/silc-channels.c.
1081 * Added SilcClientStatus field to the SilcClientEntry in the
1082 lib/silcclient/idlist.h.
1084 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1085 is incomplete and is being resolved, it won't be resolved
1088 Make sure also that USERS command reply does not resolve
1089 twice information. Affected file is
1090 lib/silcclient/command_reply.c.
1092 Make sure that silc_client_get_clients_by_list does not
1093 resolve twice same information.
1095 * Check for valid client->id in the silc_server_free_client_data.
1096 Affected file silcd/server.c.
1098 * Fixed /GETKEY nick@server not to crash if the server entry
1099 is not found. Affected file lib/silcclient/command.c.

1104 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1106 * Better checks for non-printable chars in nick added.
1107 Affected file silcd/command.c.
1109 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1111 * Call the silc_server_udpate_servers_by_server in the
1112 primary router that comes back online in the backup resuming
1113 protocol. Otherwise it routes packets wrong. Affected file
1114 silcd/server_util.[ch], silcd/server_backup.c.
1116 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1118 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1119 lib/silcutil/silcbuffmt.[ch].
1121 * Redefined the SILC packet header to include the padding
1122 length. Affected file lib/silccore/silcpacket.[ch].
1124 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1125 length for maximum padding up to 128 bytes). Affected
1126 file lib/silccore/silcpacket.h.
1128 * Removed all backwards support for old 0.5.x MAC thingies.
1129 The SILC packet header change makes it impossible to be
1130 backwards compatible.
1132 * Send the ENDING packet with timeout in the backup resuming
1133 protocol. This is to assure that all routers has connected
1134 to the primary router. Affected file silcd/server_backup.c.
1136 * Changed the RNG to take the first IV from random data. It
1137 used to take it from zero actually. Changed the RNG also
1138 to use /dev/urandom during session. /dev/random is used
1139 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1141 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1143 * Changed the SILC packet header to have the first two bytes
1144 (the packet length) encrypted. Affected files aroung the
1145 code tree, lib/silccore/silcpacket.[ch]. Removed the
1146 SilcPacketCheckDecrypt callback. It is not needed anymore
1147 since the silc_packet_receive_process will determine now
1148 whether the packet is normal or special.
1150 * Implemented the unidirectional MAC keys. Affected files
1151 lib/silcske/silcske.c, silcd/protocol.c and
1152 lib/silcclient/protocol.c.
1154 * Implemented the packet sequence number to the MAC computation.
1155 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1156 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1157 lib/silcclient/protocol.c.
1159 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1161 * Allow backup router to announce servers. All servers
1162 announced by backup router are added to the global list
1163 automatically. Update hte server's socket to our primary
1164 router also when backup router announces a server.
1165 Affected file silcd/packet_receive.c.
1167 * Do not update the client->router in the function
1168 silc_server_udpate_clients_by_server if the client is on
1169 global list. We might fail to find any specific server
1170 for locally connected clients and local cell clients. They
1171 should still use the `from' and not `to' as client->router.
1172 This fixes backup router resuming protocol. Affected file
1173 silcd/server_util.c.
1175 * Decrease channel statistics count only if the channel
1176 deletion worked. Affected files are silcd/server.c and
1177 silcd/server_util.c.
1179 * Added silc_server_update_servers_by_server to update origin
1180 of all server entries. Used during backup router protocol.
1181 Affected files silcd/server_util.[ch], silcd/server.c. and
1182 silcd/backup_router.c.
1184 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1185 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1186 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1187 lib/silccrypt/silchmac.c.
1189 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1191 * Assure that router cannot reroute the same channel message
1192 to the sender. Affected file silcd/packet_receive.c.
1194 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1196 * Made better checks that the channel message is not sent
1197 to the router it came from. Affected file is
1198 silcd/packet_send.c. Fixed memory leak too.
1200 * Announce informations for incoming router connection, but
1201 only after checking if it is replaced by backup router.
1202 Affected file silcd/packet_receive.c.
1204 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Fixed the backup resuming protocol to work in multiple
1207 router environment. Affected file silcd/server_backup.c.
1209 * Route packet only to one router in the function
1210 silc_server_packet_send_to_channel. Affected file is
1211 silcd/packet_send.c.
1213 * Fixed silc_server_send_notify_dest to set the broadcast
1214 flag. Fixed the silc_server_send_notify_topic to actually
1215 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1216 Affected file silcd/packet_send.c.
1218 * Changed the SFTP Filesystem interface. Changed the
1219 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1220 the filesystem operation function. The SilcSFTPFilesystem
1221 is now a context that is allocated by all filesystem allocation
1222 functions and it already includes the operations structure
1223 and filesystem specific context. It is given as argument
1224 now to the silc_sftp_server_start. This made the interface
1225 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1226 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1228 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1230 * Changed the backup router adding and getting interfaces
1231 in the server. The router that will be replaced by the
1232 specified backup router is now sent as argument. Affected
1233 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1236 * Added silc_net_addr2bin_ne to return the binary form of
1237 the IP address in network byte order. Affected files
1238 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1240 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1242 * Check for existing server ID in silc_server_new_server
1243 and in silc_server_connect_to_router_final and remove the
1244 old entry if it exists. Affected file silcd/packet_receive.c,
1247 * Send the channel message always to only one router, either
1248 in upstream or downstream. Affected file is
1249 silcd/packet_send.c.
1251 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Wrote the definition of the backup resuming protocol to the
1254 protocol specification.
1256 * Removed one redundant channel key generation from normal
1257 server during joining procedure. Removed one redundant
1258 channel key sending from server to router during joining
1259 procedure. Affected file silcd/command.c.
1261 * Made minor bugfixes to the backup router resuming protocol.
1262 Affected file silcd/server_backup.c, server.c.
1264 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Added --disable-asm configuration option. Affected files
1267 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1270 * Implemented the backup resuming protocol that is used to
1271 resume the primary router position in the cell after the
1272 primary router comes back online. Affected files
1273 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1274 and silcd/server_util.[ch].
1276 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1278 * Sleep two (2) seconds after sending QUIT command to server.
1279 Affected file lib/silcclient/command.c.
1281 * Assure that if outgoing data buffer is pending do not force
1282 send any data. Affected file silcd/packet_send.c.
1284 * Assure that if outgoing data buffer is pending do not force
1285 send any data. Affected file lib/silcclient/client.c.
1287 * Implemented the backup router support when the primary router
1288 goes down. The servers and routers can now use the backup
1289 router as new primary router without loosing connectivity.
1291 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1294 in the server to indicate disabled entry. All data read
1295 from the connection will be ignored and no data is sent
1296 for entry that is disabled. Affected files are
1297 silcd/idlist.h, silcd/server.c.
1299 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1301 * Created SFTP client and server test programs in the
1302 lib/silcsftp/tests directory.
1304 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1306 * Implemented memory filesystem (virtual filesystem) for
1307 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1310 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Implemented the SFTP (SSH File Transfer Protocol) to the
1313 lib/silcsftp. It includes SFTP client and SFTP server
1316 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1318 * Moved lib/silccore/silcprotocol.[ch] to the
1319 lib/silcutil library.
1321 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1322 take variable argument list pointer as argument. Affected
1323 file lib/silcutil/silcbuffmt.[ch].
1325 * Added silc_buffer_set function that is used to set data
1326 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1327 Affected file lib/silcutil/silcbuffer.h.
1329 * Changed various routines in the core library to use the new
1330 silc_buffer_set instead of allocating new buffer only for
1333 * Added 64-bit value formatting and unformatting support to the
1334 silc_buffer_[un]format routines. Affected file is
1335 lib/silcutil/silcbuffmt.[ch].
1337 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1338 to includes/bitmove.h.
1340 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Fixed channel user mode saving in client library. Affected
1343 file lib/silcclient/command[_reply].c.
1345 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1347 * Defined the file transfer to the SILC Protocol. Added
1348 new packet type SILC_PACKET_FTP and defined File Transfer
1349 Payload. The mandatory file transfer protocol is SFTP
1350 (SSH File Transfer Protocol). Affected file in addition
1351 of the internet draft is lib/silccore/silcpacket.h.
1353 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1354 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1355 is used as part of backup router protocol when the primary
1356 router of the cell is back online and wishes to resume
1357 the position as primary router.
1359 * Redefined the MAC generation keys in the protocol. The
1360 same key is not used anymore in both direction. Both
1361 direction will now use different keys for sending and
1362 receiving. This fixes a potential security flaw. This
1363 change causes incompatibilities in the protocol.
1365 * Redefined also the MAC computation from the packet.
1366 An packet sequence number is now added to the MAC
1367 computation. This prevents possible replay attacks against
1368 the protocol. This change too causes incompatibilities
1371 Added `sequence' field to the SilcPacketContext to hold
1372 the current sequence number for the packet.
1374 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1376 * Added `created' field to the SilcIDListData in the file
1377 silcd/idlist.h to indicate the time when the entry was
1380 * Added `created' field to the SilcChannelEntry too. Affected
1381 file silcd/idlist.h.
1383 * Added `creation_time' aguments to all the announcement functions
1384 in the server. If it is provided then only the entries that
1385 was created after the provided time frame are actually
1386 announced. Affected file silcd/server.[ch].
1388 * The protocol says that the Channel ID's IP address must be
1389 based on the router's IP address. Added check for this in
1390 the silc_server_new_channel when processing incoming New Channel
1391 Payload. Affected file silcd/packet_receive.c.
1393 * Print out the correct version with --version in SILC client.
1394 Affected file irssi/src/silc/core/silc-core.c.
1396 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * Fixed WHOWAS command to check for completnes of the client
1399 entry always, not just when the command is coming from client.
1400 Affected file silcd/command.c.
1402 * Added new function silc_server_packet_queue_purge to purge the
1403 outgoing data queue to the network. After the function returns
1404 it is guaranteed that the outgoing packet queue is empty.
1405 Affected file silcd/packet_send.[ch].
1407 * Purge the outgoing packet queue in the rekey protocol's final
1408 callback to assure that all rekey packets go to the network
1409 before quitting the protocol. Affected file silcd/server.c.
1411 * Added silc_client_packet_queue_parse as similar function as
1412 in server to the client library. The affected file is
1413 lib/silcclient/client.c.
1415 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Splitted silcd/server.c and created silcd/server_util.[ch]
1418 for utility functions.
1420 * Added new socket flag SILC_SF_DISABLED to indicate that the
1421 connection is open but nothing can be sent to or received from
1422 the connection. Affected file lib/silcutil/silsockconn.[ch].
1423 The checking for disabled socket is checked in the low level
1424 silc_socket_write and silc_socket_read functions.
1426 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1428 * Allow only nicknames and channel names that fits into the
1429 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1431 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * When processing JOIN command reply in server check that if
1434 the channel exists in our global list we'll move it the local
1435 list. Affected file silcd/command_reply.c.
1437 * Fixed the check whether client is joined on the channel already
1438 in JOIN command. Affected file lib/silcclient/command.c.
1440 * Fixed the JOIN command reply to check whether the channel
1441 already exists. Affected file lib/silcclient/command_reply.c.
1443 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * Added silc_ske_status_string to map the SKE error numbers
1446 to readable strings. The affected files are
1447 lib/silcske/silcske[_status].[ch].
1449 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Do not show the private channels on the WHOIS channel list
1452 as it is not allowed by the protocol. The affected file is
1455 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Assure that the packet length digged from the actual packet
1458 is something sensible in the silc_packet_decrypt_rest_special
1459 in lib/silccrypt/silcpacket.c.
1461 * Free and NULL the allocated pointer in silc_hmac_alloc if
1462 the HMAC allocation fails. The affected file is
1463 lib/silccrypt/silchmac.c.
1465 * Print the selected security properties to the log files in
1466 the server. Affected file silcd/protocol.c.
1468 * Add SKE's reference counter even if calling the completion
1469 callback manually. Otherwise it goes negative, although it
1470 does not cause any problems. The affected file is
1471 lib/silcske/silcske.c.
1473 * Remove the client entry with short timeout after giving the
1474 KILL command. Affected file lib/silcclient/command.c.
1476 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1477 case all found clients are already disconnected (WHOWAS would
1478 found them) in the server. Affected file silcd/command.c.
1480 * Update the last_receive (time of last data received) to be
1481 updated only when received private or channel message so that
1482 the idle time showed in WHOIS makes more sense.
1484 * Added boolean field `valid' in to the SilcClientEntry in the
1485 client library to indicate whether the entry is valid or not.
1486 This fixes the nickname change bug on channel when changing
1487 the nickname to be same than the old (like nick to Nick) the
1488 nickname formatter doesn't set the new nick anymore to Nick@host.
1489 Affected file lib/silcclient/idlist.[ch].
1491 * Now actually fixed the nickname changing on disconnection.
1492 Added new function silc_change_nick to the Irssi SILC Client.
1493 Affected file irssi/src/silc/core/client_ops.c,
1494 irssi/src/silc/core/silc-nicklist.[ch].
1496 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1498 * Check that the public key exists in the GETKEY command before
1499 trying to encode it. Affected file silcd/command.c.
1501 * Print some notifications on received public keys with GETKEY
1502 command in the Irssi SILC Client. Affected files are
1503 irssi/src/fe-common/silc/module-formats.[ch],
1504 irssi/src/silc/core/client_ops.c.
1506 * Use IDENTIFY command to resolve the server information in the
1507 GETKEY command instead of INFO command. Affected file
1508 lib/silcclient/command.c.
1510 * All command reply functions in the client library now calls
1511 the pending command reply callbacks even if an error has
1512 occurred. The server has done this a long time and now it was
1513 time to move the client library to this as well. Now all
1514 errors can be delivered back to the pending command reply
1515 callbacks if necessary. Affected files are
1516 lib/silcclient/command[_reply].[ch].
1518 * Change the nickname on disconnection back to the username
1519 because in reconnect the server will enforce it to it anyway.
1520 Affected file irssi/src/silc/core/silc-servers.c.
1522 * Fixed a config file parsing bug in the Irssi SILC client.
1523 Affected file irssi/src/silc/core/clientconfig.c.
1525 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1527 * When printing the channel mode on JOIN, verify that the
1528 channel key and channel's HMAC are valid. Affected file
1529 irssi/src/silc/core/client_ops.c.
1531 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1533 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1534 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1535 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1537 * Removed channel key rekey task deleting from the function
1538 silc_server_save_channel_key. Affected file silcd/server.c.
1539 Added explicit timeout task context instead that is used to
1540 delete the task if we are registering a new task before the
1541 new task has elapsed.
1543 * When channel key rekey occurs the client library now saves
1544 the old channel key for a short period of time (10 seconds) and
1545 is able to use it in case some is still sending channel
1546 messages encrypted with the old key after the rekey. Affected
1547 file lib/silcclient/[idlist.h|client_channel.c].
1549 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Added check to the silc_server_new_id_real to not accept
1552 new ID if it is the sender's own ID. Affected file is
1553 silcd/packet_receive.c.
1555 * Assure that we do not announce ourself or the one we've
1556 sending our announcements when we're router and are announcing
1557 servers to our primary router. Affected file silcd/server.c.
1559 * Fixed silc_server_command_identify_check_client to assemble
1560 correct WHOIS packet. It send corrupted WHOIS packet and
1561 caused problem with router to router connections. Affected
1562 file silcd/command.c.
1564 Fixed also silc_server_command_whois_check the same way
1565 as for the IDENTIFY command.
1567 * Added new SilcIDListStatus to the server in the SilcIDListData
1568 structure. The status now includes the current status of
1569 the entry (like registered, resolved etc.). Affected file
1570 silcd/idlist.[ch]. Defined a bunch of different status types
1571 as well. This replaced the old boolean registered field as well.
1573 Added resolve_cmd_ident field to the SilcClientEntry structure
1574 too so that if the entry is for example being resolved so
1575 another command may attach to the same pending command reply
1576 without requiring to resolve the same entry again. This concept
1577 should optimize the WHOIS and the IDENTIFY resolving under
1578 heavy load by taking away unnecessary resolving for entries
1579 that are being resolved already.
1581 Added support for adding multiple pending commands for one
1582 command idenfier. Affected file silcd/command[_reply].[ch].
1584 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1585 before deleting the data. Otherwise the hash table will have
1586 freed data in comparison functions. Affected file is
1587 silcd/command_reply.c.
1589 * Fixed silc_idlist_replace_client_id to add the new entry to
1590 the cache with NULL nickname. Otherwise there will be invalid
1591 memory as the nickname after the nickname is freed. Affected
1592 file silcd/packet_receive.c.
1594 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1595 saved into wrong slots because the previous number of entries
1596 was not taken into account. Affected file silcd/idlist.c.
1597 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1599 * If we are router and we receive JOIN notify to a channel that
1600 does not have any users then notified client is marked as the
1601 channel founder, as it is it. The affected file is
1602 silcd/packet_receive.c
1604 * Added to the extended hash table API's table_del_*ext functions
1605 the destructor as argument too, so that the caller can decide
1606 which destructor to use or whether to use destructor at all.
1607 Affected file lib/silcutil/silchashtable.[ch].
1609 * Fixed ID Cache purging. It actually deleted the entries from
1610 the hash table after the data was freed. The hash table ended
1611 up comparing freed memory. The affected file is
1612 lib/silccore/silcidcache.c.
1614 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1616 * Fixed Irssi SILC client's KILL command's HELP syntax.
1618 * The USERS command now resolves the detailed user information
1619 if the userinfo field is missing. Affected file is
1620 lib/silcclient/command_reply.c.
1622 * Do not print error in silc_file_read if the read file does
1623 not exist. Just silently return NULL. Affected file is
1624 lib/silcutil/silcutil.c.
1626 * Fixed the silc_log_output to not wine about NULL filename
1627 and to not create some bogus " " filename. Affected file is
1628 lib/silcutil/silclog.c.
1630 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1632 * Fixed various printing bugs on the user interface in the
1633 Irssi SILC Client. Minor changes that were forgotten from
1636 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1638 * Fixed the configure.in.pre and the compilation and distribution
1639 environment to support the new autoconf 2.52. That version is
1640 now required to compile the CVS trunk.
1642 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1644 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1645 to generally parse user@fqdn format strings. Affected file
1646 lib/silcutil/silcutil.c.
1648 * Added nickname_format and nickname_force_format fields to the
1649 SilcClientParams structure. The first one defines the format
1650 for the nicknames that the library will enforce if the receives
1651 multiple same nicknames. The second one is boolean value and
1652 can be used to force the library to always enforce the format
1653 to the nicknames regardles whether there are multiple nicknames
1654 or not. This configurable formatting was employed to flexibly
1655 support accessing multiple nicknames from the user interface.
1656 The userinterface can now set the nicknames to what ever format
1657 they prefer. Affected file lib/silcclient/silcapi.h.
1659 Added function silc_client_nickname_format to the file
1660 lib/silcclient/idlist.c. It performs the nickname formatting.
1662 Added new field `hostname´ to the SilcClientEntry context.
1663 It holds the hostname of the client. Affected file is
1664 lib/silcclient/idlist.h.
1666 * Irssi SILC Client sets the nicknames in nick@hostn format.
1667 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1668 irssi/src/silc/core/silc-core.c.
1670 The WHOIS printing now also shows both the real nickname and
1671 the formatted nickname so that user knows how to access the
1672 user if there are multiple same nicknames cached. Affected
1673 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1674 printing formatting too to take the hostname now as a separate
1675 argument. The Affected file is
1676 irssi/src/fe-common/silc/modules-formats.[ch].
1678 * Changed the silc_client_get_clients_local to accept the formatted
1679 nickname as argument. It accepts the real nickname too but the
1680 formatted nickname can be used to find the true entry from
1681 multiple entries. Affected file lib/silcclient/silcapi.h and
1682 lib/silcclient/idlist.c.
1684 * Added nickname_format_parse field to the SilcClientParams.
1685 It is a callback function provided by the application to parse
1686 the nickname out of the formatted nickname string. The library
1687 calls it to get the nickname from the formatted string. Since
1688 the application generally knows better the format of the nickname
1689 string it parses it instead of the library, even though library
1690 encodes the formatted string. If the callback function is not
1691 provided then the library will use the string as is. The
1692 affected file is lib/silcclient/silcapi.h.
1694 * All the nickname strings passed to the client library in
1695 commands are now expected to be formatted nickname strings.
1696 If the command does not support the formatted nickname string
1697 it will assume that the sent string is the actual nickname.
1698 Affected file lib/silcclient/command.c.
1700 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1702 * Added public key authentication support to OPER and SILCOPER
1703 commands in the client library. Affected file is
1704 lib/silcclient/command.c.
1706 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Changed the get_auth_methdod client operation to be asynchronous.
1709 It can be async if the application resolves the authentication
1710 method from the server during the negotiation. Added new
1711 SilcGetAuthMeth completion callback that the application will
1712 call after resolving the authentication method.
1714 Added function silc_client_request_authentication_method that
1715 the application can use to resolve the authentication method
1716 from the server. Added also SilcConnectionAuthRequest callback
1717 that the library will call after the server has replied. The
1718 application can call this function if it does not know the
1719 current authentication method.
1721 Affected files are lib/silcclient/client.c and
1722 lib/silcclient/silcapi.h.
1724 * The Irssi SILC client now automatically resolves the authentication
1725 method incase any configuration information is not present (and
1726 currently there never is). The affected file is
1727 irssi/src/silc/core/client_ops.c.
1729 * Fixed public key authentication from the client library.
1730 Affected file lib/silcclient/protocol.c. Changed also the
1731 protocol specification about the public key authentication in
1732 the connection authentication protocol. The actual data to be
1733 signed is now computed with a hash function before signing.
1735 * Fixed the public key authentication from the server as well.
1736 Affected file silcd/protocol.c.
1738 * Removed the mlock()'s from the memory allocation routines.
1739 Affected file lib/silcutil/silcmemory.c. The ./configure does
1740 not check anymore for the mlock(). Affected file is
1743 * Fixed USERS command in server to allow the execution of the
1744 command for private and secret channels if the client sending
1745 the command is on the channel. Affected file silcd/command.c.
1747 * Fixed silc_client_get_clients_local to return the clients
1748 count correctly. It could return wrong value. Affected file
1749 lib/silcclient/idlist.c.
1751 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1753 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1754 types. The assembler optimizations seemed not to like 64-bit
1755 data types. The assmebler optimizations thus are now enabled
1756 also for BSD systems as opposed to only enable them for Linux.
1758 * Do not check for threads at all on BSD systems. Affected
1759 file configure.in.pre.
1761 * Removed -n and -h options from the Irssi SILC Client since
1762 they are not used in silc.
1764 * Fixed the prime generation to assure that the first digit
1765 of the generated random number is not zero since our conversion
1766 routines does not like number strings that starts with zero
1767 digit. If zero digit is seen the random number is regenerated.
1768 This caused some corrupted RSA keys when the zero first digit
1769 was met. Affected file lib/silcmath/silcprimegen.c.
1771 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1773 * Fixed WIN32 configuration in the ./configure script.
1774 Fixed to include xti.h on environments that has it.
1775 Patches by Carsten Ilchmann and andrew.
1777 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1779 * Changed the silc_id_create_client_id to be collision
1780 resistant. It is now assured that there cannot be created
1781 two same client ID's. I suspect that some weird bugs in
1782 the server were actually caused by duplicate Client IDs.
1783 Affected file silcd/serverid.[ch]. A router receiving
1784 new ID now also assures and informs the sending server
1785 if the ID caused collision.
1787 * Changed the silc_id_create_channel_id to also assure that
1788 there are no collisions.
1790 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Statement about ignoring the Mutual Authentication flag when
1793 performing rekey with PFS was a bit misleading. It is ignored
1794 if it was set in the initial negotiation, it cannot be even
1795 set in the rekey. Fixed in the ke-auth draft. Started the
1796 new versions of the protocol drafts in the doc/.
1798 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1800 * Fixed a bug in silc_client_command_identify_save when saving
1801 new channel information. The channel name was no duplicated
1802 and caused crash on exit. Affected file is
1803 lib/silcclient/command_reply.c.
1805 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1807 * Fixed the getkey command handling in the server. Send just
1808 empty OK reply to the sender if the key could not be fetched
1809 (but everything else was ok, like the key just was not available).
1810 Changed the public key parameter to optional in the protocol
1811 specs so that empty OK reply can be sent. Affected file
1814 Added a message to Irssi SILC client to tell to user if the
1815 server did not return a public key.
1817 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1819 * Fixed a channel key regeneration bug. It registered new
1820 timeout tasks exponentially until all system resources were
1821 used. Affected file silcd/server.c.
1823 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1825 * Added the SILC Document generator to the scripts/silcdoc.
1826 It can be used to generate the Toolkit Reference Manual out
1827 of the source tree. Internally it will also use the RoboDoc
1828 generator now imported in util/robodoc.
1830 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1832 * Added couple of return's in rekey protocol if error orccurred
1833 during the protocol. The execution must be terminated.
1834 Affected file silcd/protocol.c. Also, terminate the protocol
1835 always with timeout.
1837 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * The client's Client ID was created initally from the wrong
1840 nickname (it could have been in format nick@host) in the
1841 silc_server_new_client. Affected file silcd/packet_receive.c
1843 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Added some SILC_LOG_ERROR's to various error conditions
1846 if client could not be added to ID cache. Affected files
1847 silcd/packet_receive.c and silcd/server.c.
1849 * When client's sock->user_data is freed, NULL also the
1850 client->router and client->connection pointers. Added check
1851 for these pointers being NULL to various places around the
1852 code. Affected file silcd/server.c.
1854 * Added client->data.registered == TRUE checks to various
1855 places around the code to assure that unregistered client's
1856 are not handled when it is not allowed. Affected file
1859 * Added `bool registered' fields to all
1860 silc_idlist_[server|client]_get_* routines to indicate whether
1861 the fetched client needs to be registered or not. Affected
1862 file silcd/idlist.[ch].
1864 * Add your own entry as registered to the ID cache in the
1865 server. Affected file server.c.
1867 * Fixed a bug in silc_server_new_server. The SilcServer was
1868 set as the new server's context instead of SilcServerEntry.
1869 This naturally caused some weird bugs.
1871 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1873 * Do not delete the channel rekey task when adding it
1874 for in silc_server_create_channel_key.
1876 * Changed the silc_server_create_channel_key to return
1877 TRUE or FALSE to indicate the success of the channel key
1880 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1882 * Fixed MSVC++ project files and added missing files to
1883 Makefiles under win32/.
1885 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Do not add TCP_NODELAY flag if the operating system
1888 does not have it defined. Affected files are
1889 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1891 * Fixed buffer overflow from Irssi SILC Client. Affected
1892 file irssi/src/fe-common/core/themes.c.
1894 * Fixed double free in client library in the file
1895 lib/silcclient/client.c when disconnecting from server.
1897 * Applied double free patch from cras to Irssi SILC client.
1898 Affected files irssi/src/core/[modules/expandos].c
1900 * Fixed the disconnection handling to Irssi SILC Client.
1901 The application must call silc_client_close_connection
1902 in ops->connect client operation in case of failure of
1903 the connection. Affected file is
1904 irssi/src/silc/core/client_ops.c.
1906 * Do not set sock->protocol to NULL in the function
1907 silc_client_close_connection after executing the protocol's
1908 final callback since the sock might not be valid anymore.
1909 Affected file lib/silcclient/client.c.
1911 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Do not enable SILC_THREADS if the linking with libpthread
1914 did not happen. Affected file configure.in.pre.
1916 * Added notion to protocol specification that server must
1917 verify the sent authentication payload with CMODE when
1918 setting the channel founder key. Implemented it to the
1919 server. Affected file silcd/command.c.
1921 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1923 * Added _EXTRA_DIST SILC distribution variable to the
1924 distributions file. It is used to conditionally add extra
1925 files or directories to the specific distribution. Affected
1926 files ./prepare, Makefile.am.pre and distributions.
1928 Removed the `_' from the start of the distribution names.
1931 * Added README.WIN32 for instructions to compile the Toolkit
1934 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Fixed a double free in disconnection in the server. Affected
1937 file is silcd/server.c.
1939 * Fixed the lib/silcske/groups.c to work now also with GMP
1940 MP library. The string conversion did not work when using
1941 specific base and the base is indicated in the string as well.
1943 * Created win32/ directory which now includes MSVC++ specific
1944 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1945 It will appear only in the toolkit distribution
1947 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1949 * Changed the key material distribution function in case when
1950 the hash output is too short. The data is now concatenated
1951 a bit differently than it used to. Made the change to the
1952 SKE protocol specification.
1954 * Added better GMP detection to configure.in.pre. A patch
1957 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Fixed a minor bug in SKE that might cause some problem on
1960 some platforms. Affected file lib/silcske/silcske.c.
1962 * Added the cookie checking for initiator in the SKE. It checks
1963 that the responder returns the sent cookie unmodified. The
1964 affected file is lib/silcske/silcske.c. Added new SKE
1965 error type INVALID_COOKIE that can be sent during the
1966 negotiation. Fixed some memory leaks as well.
1968 * Added the "invalid cookie" error message to Irssi SILC client's
1971 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Added `task_max' field to the SilcClientParams to indicate
1974 the maximum tasks the scheduler can handle. If set to zero,
1975 default values are used. Affected file lib/silcclient/silcapi.h.
1977 * Fixed memory leaks in silc_client_close_connection. Affected
1978 file lib/silcclient/client.c.
1980 * Added silc_client_del_client_entry to client library to free
1981 all memory of given client entry. Affected file is
1982 lib/silcclient/idlist.[ch].
1984 * Added new functions silc_client_del_channel and
1985 silc_client_del_server to delete channel and server entries.
1986 Affected file lib/silcclient/[silcapi.h/idlist.c].
1988 * Removed silc_client_del_client_by_id from silcapi.h.
1990 * Fixed the INFO command to return the server's own info
1991 correctly when querying by Server ID. Affected file is
1994 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1996 * Removed the non-blocking settings in WIN32 code in the
1997 silc_sock_[read/write] and added SleepEx instead. Affected
1998 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1999 of input data is now checked with FIONREAD and ioctlsocket.
2001 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * Call silc_schedule_task_del_by_context in the
2004 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2005 Affected file lib/silccore/silcprotocol.c.
2007 * Call silc_protocol_cancel for active protocols in the
2008 silc_server_close_connection if the funtion
2009 silc_server_free_sock_user_data has not been called.
2010 Affected file silcd/server.c.
2012 * Generic tasks cannot be deleted using the del_by_fd
2013 task deleting function since generic tasks does not match
2014 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2016 * Added a notion to SILCOPER help file that the SILCOPER works
2017 only on router server, not on normal server.
2019 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2021 * Added for WIN32 support for the new scheduler as well.
2022 Affected file lib/silcutil/win32/silcwin32schedule.c.
2024 * Fixed the SHA1 implementation to work on various platforms.
2026 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2029 API. It is part of the scheduler now. Everything else is
2030 as previously but some functions has changed their names.
2031 Checkout the lib/silcutil/silcschedule.h for the interface.
2032 Updated all applications to use the new interface. Affected
2033 files are lib/silcutil/silcschedule.[ch].
2035 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Found a bug in the SKE implementation. The HASH value,
2038 specified by the protocol, was not computed correctly. The
2039 public key of the responder was not added to the computation
2040 even though it is mandatory. Affected file lib/silcske/silcske.c.
2041 This unfortunately causes incompatibilities with older
2042 clients and servers.
2044 * Added WIN32 specific network init and uninit functions:
2045 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2046 the Winsock2. Affected file lib/silcutil/silcnet.h and
2047 lib/silcutil/win32/silcwin32net.c.
2049 * Set the socket always to nonblocking mode on WIN32 after
2050 reading data or writing data. Affected file is
2051 lib/silcutil/win32/silcwin32sockconn.c.
2053 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * Fixed various compilation problems under WIN32. Affected
2056 files lib/silcutil/win32/silcwin32thread.c and
2057 lib/silcutil/win32/silcwin32schedule.c.
2059 * Removed all _internal.h #includes from public header
2060 files. Internal headers must never be included from
2063 Removed also the lib/silcske/payload_internal.h file.
2065 * All include files that may be needed (public and some others
2066 included by the public headers) by application developers are
2067 now copied to the ./includes directory. It does not copy any
2068 internal headers. Affected file Makefile.defines.pre and all
2069 Makefile.am's under lib/ and subdirs.
2071 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Do not change the ~/.silc directory's permissions automatically.
2074 Affected file irssi/src/silc/core/clientutil.c.
2076 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * Do not cancel the protocol in silc_server_close_connection
2079 it might cause recursion. Now cancelled in the function
2080 silc_server_free_sock_user_data. Affected file silcd/server.c.
2082 * Fixed the silc_server_remove_clients_by_server to regenerate
2083 the channel keys correctly finally. Added also new function
2084 silc_server_remove_clients_channels to actually do it.
2085 Affected file silcd/server.c.
2087 * Fixed the silc_server_new_channel to not crash by giving
2088 wrong router to the new channel. Affected file is
2089 silcd/packet_receive.c.
2091 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2093 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2094 which is given as argument to the silc_client_alloc now.
2095 It can be used to configure the client and set various parameters
2096 that affect the function of the client.
2098 * The USERS command in server did not check whether the channel
2099 is private or secret. Affected file silcd/command.c.
2101 * Added new argument to the USERS command in protocol specification.
2102 The USERS command now can take the channel name as argument
2103 as well. Added support for this in client and server and
2104 updated the protocol specs.
2106 * Completed the GETKEY command in client. It can be now used
2107 to fetch also servers public key not only some clients.
2108 Affected files lib/silcclient/command[_reply].c.
2110 * Added silc_client_get_server to return server entry by the
2111 server name. Affected files lib/silcclient/silcapi.h and
2114 * Redefined the IDENTIFY command in protocol specification to be
2115 more generic. It now can be used to query information about
2116 any entity in the SILC Network, including clients, servers and
2117 channels. The query may be based either the entity's name
2118 or the ID. Added support for this in both client and server.
2120 Affected files silcd/command.c and lib/silcclient/command.c
2121 and command_reply.c.
2123 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2124 the _from_client and _from_server functions. Affected file
2127 * Added silc_client_get_channel_by_id_resolve to the file
2128 lib/silcclient/silcapi.h to resolve channel information by
2129 its ID. Added also silc_client_get_channel_by_id that
2130 does not resolve it from the server.
2132 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Added SilcServerEntry context into the client library
2135 to represent one server. The INFO command now allocates
2136 these to save the resolved server info. For now on the
2137 client library will also keep information about servers,
2138 connected and resolved with INFO.
2140 The INFO command now allocates the SilcServerEntry context
2141 and saves the server info there. The COMMAND_REPLY in
2142 the INFO now returns the parameters to application in
2143 same order as defined in the protocol specification.
2145 The entries are cached in the client->server_cache.
2147 * The INFO command is now issued after received the Client ID
2148 from the server. Affected file lib/silcclient/client.c.
2150 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2151 to the application as the mode changer might be server.
2152 It is guaranteed that NULL is not returned anymore to the
2153 application. Affected file lib/silcclient/client_notify.c.
2155 The ID Type is now also passed to the application so that
2156 it can check whether the returned entry is SilcClientEntry
2159 Added new function silc_client_get_server_by_id to return
2160 the server entry by ID. Affected files are the
2161 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2163 * Do not create the channel in the Irssi SILC Client when issuing
2164 the JOIN command but when received the sucessful JOIN command
2165 reply. Otherwise the channel might get created even though we
2166 could not join it. The Affected file is
2167 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2169 * Fixed a channel joining bug in router. The router must also
2170 check the channel modes, invite and ban lists etc. when serving
2171 the JOIN command sent by normal server. Affected file is
2172 silcd/command.c. The router now resolves the client's
2173 information from the server who sent the JOIN command if it
2174 does not know it, and processes the JOIN command only after
2177 * Changed the SilcCommandCb to take new argument; void *context2.
2178 Affected file lib/silccore/silccommand.h
2180 The second argument in the command callbacks in the server now
2181 includes the SilcServerCommandReplyContext if the command was
2182 called as pending command callback from the command reply.
2183 Otherwise it is NULL. When called as pending the status of the
2184 command reply will be checked and if it was erronous the
2185 error will be sent to the original sender of the command.
2186 This way the client always receives the error messages even
2187 though the server was actually the one who received the error
2188 when it resent the command to router, for example. Affected
2189 files silcd/command[_reply].[ch].
2191 * Fixed sending WHOWAS command's error message to client if
2192 the requested client could not be found. It was missing.
2195 * Changed the CMODE and CUMODE commands reply arguments in the
2196 protocol specification. The Channel ID is now sent in both
2197 of the commands to identify the channel. Implemented this
2198 new feature to the client and server. Affected files
2199 lib/silcclient/command_reply.c and silcd/command.c.
2201 * Made better checks for invite and ban lists in the JOIN
2202 command in server. Affected file silcd/command.c.
2204 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2206 * The server now performs the incoming host IP/DNS lookup
2207 using the silc_socket_host_lookup and thus does not block
2208 the server anymore. Affected file silcd/server.c.
2210 * Completed the multi-thread support for SILC Scheduler in
2211 the lib/silcutil/silcschedule.c.
2213 * Fixed the configure.in.pre to detect the pthread correctly
2216 * Fixed a deadlock in silc_task_queue_wakeup in the file
2217 lib/silcutil/silctask.c.
2219 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Added new function silc_schedule_wakeup that is used in
2222 multi-threaded environment to wakeup the main thread's
2223 schduler. It needs to be used when a thread adds a new task
2224 or removes a task from task queues. After waking up, the
2225 scheduler will detect the task queue changes. If threads
2226 support is not compiled in this function has no effect.
2227 Implemented the wakeup mechanism to both Unix and WIN32
2228 systems. Affected files are lib/silcutil/silcschedule.[ch],
2229 lib/silcutil/unix/silcunixschedule.c and the
2230 lib/silcutil/win32/silcwin32schedule.c.
2232 * Added new function silc_task_queue_wakeup to wakeup the
2233 scheduler by the specified task queue. Affected file
2234 lib/silcutil/silctask.[ch].
2236 * The silc_socket_host_lookup_start now wakes up the scheduler
2237 after adding the timeout task. Affected file is
2238 lib/silcutil/silcsockconn.c.
2240 * The silc_socket_host_lookup is synchronous now if the threads
2241 support is not compiled in. However, the callback is still
2242 called asyncronously through the scheduler, anyway. Affected
2243 file lib/silcutil/silcsockconn.c.
2245 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * Added new function silc_socket_host_lookup to perform
2248 asynchronous IP and FQDN lookups for the socket connection.
2249 Affected files lib/silcutil/silcsockconn.[ch].
2251 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2254 that may or may not compile the mutex support in.
2256 Changed the silc_mutex_alloc interface. It allocates the
2257 mutex now to the sent pointer and returns TRUE or FALSE.
2259 Affected file lib/silcutil/silcmutex.h.
2261 * Wrote the SILC Task Queue interface to support multi-threads.
2262 Affected file lib/silcutil/silctask.[ch].
2264 * Wrote the SILC Scheduler to support multi-threads. Affected
2265 file lib/silcutil/silcschedule.c.
2267 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2269 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2270 in lib/silcutil/win32/.
2272 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Defined SILC Mutex API and SILC Thread API and implemented
2275 them for Unix. Affected files are
2276 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2277 lib/silcutil/unix/silcunixmutex.c and
2278 lib/silcutil/unix/silcunixthread.c.
2280 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Fixed the silc_server_remove_clients_by_server's channel
2283 key re-generation. The hash table handling was incorrect
2284 and would not work with many channels. Affected file is
2287 * Fixed some memory leaks around the server code.
2289 * Rewrote the silc_server_get_users_on_channel to support IPv6
2290 based Client ID's. Affected file silcd/server.c.
2292 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2293 specification. However, a separate document must be written
2294 to define the detailed signing procedure and the payload
2295 associated with the flag. Defined the flag to the
2296 lib/silccore/silcchannel.h as well.
2298 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Changed the dynamic tables to static size tables in the
2301 lib/silccrypt/silchmac.c.
2303 * Removed GCC dependencies from the code. A patch by cras.
2305 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Do not show the error "Error receiving packet bla bla"
2308 in server if it really was not an error (-2 means that reading
2309 is pending). Affected file silcd/server.c.
2311 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2313 * Fixed a possible crash in silc_server_remove_clients_by_server
2314 in silcd/server.c. Fixed there also some memory leaks.
2316 * Fixed the silc_idlist_replace_client_id. It could replace
2317 wrong key in the hash table. Affected file silcd/idlist.c.
2319 * Do not check whether there are global users on the channel
2320 if the channel->global_users is FALSE. Affected functions
2321 silc_server_remove_from_one_channel and
2322 silc_server_remove_from_channels in silcd/server.c. Also,
2323 do not check if the removed client is local as we can be
2324 sure that global client was not removed from the channel
2325 and checking for global users is not needed.
2327 * The silc_server_remove_clients_by_server now re-generates
2328 the channel keys correctly for those channels that had
2329 clients removed from them. Affected file silcd/server.c.
2331 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2333 * Found the reason of random crashes in the server. We weren't
2334 ignoring the SIGPIPE signal (which can be sent in write())
2335 and it crashed the server. Affected file silcd/silcd.c.
2337 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2339 * Assure that sock->user_data is not NULL in the function
2340 silc_server_packet_send in silcd/packet_send.c.
2342 * Disconnect the remote connection if it could not be added
2343 to any ID lists in the server. The affected file is
2346 * Check in silc_server_packet_send[_real/dest] that the
2347 socket is not disconnecting and ignore the data if it is.
2348 Affected file silcd/packet_send.c.
2350 * Define inline to __inline on native WIN32 compilation.
2351 Affected file includes/silcwin32.h.
2353 * Added some explicit type casts for inline code since MSVC
2354 require them. Affected files lib/silcutil/silcbuffer.h,
2355 lib/trq/silcdlist.h and lib/trq/silclist.h.
2357 * Print warning in log files from now on if the packet
2358 decryption fails. Affected file silcd/server.c.
2360 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2362 * Changed the `say' client operation's interface to accept
2363 new `type' argument to indicate the type of the message sent
2364 by the library. The application may filter the library's
2365 messages according the type. The affected file is the
2366 lib/silcclient/silcapi.h.
2368 * Added two new functions to lib/silcclient/silcapi.h:
2369 silc_client_del_client and silc_client_del_client_by_id.
2370 Affected file lib/silcclient/idlist.c.
2372 * Moved the clientincludes.h from includes/ to silc/ and
2373 serverincludes.h from includes/ to silcd/.
2375 * The modes for the CMODE and CUMODE are now passed as
2376 uint32 for application with COMMAND_REPLY. The affected
2377 file is lib/silcclient/command_reply.c.
2379 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2381 * /WHOIS without arguments shows client's own information.
2382 Affected file lib/silcclient/command.c.
2384 * Changed PING to not accept any arguments. The specs
2385 says that client can ping only the connected server so
2386 requiring an argument is not needed. Affected file is
2387 lib/silcclient/command.c.
2389 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2391 * Fixed a fatal bug in private message sending and reception
2392 encryption and decryption when using private message keys.
2393 The implementation was incorrect and did not follow the
2394 specification. It causd that some of the message were
2395 lost since it did not use the sending and receiving keys
2396 as the protocol suggests. This has been fixed and will cause
2397 incompatibilities with older clients when sending private
2398 message encrypted with private message keys. Affected files
2399 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2400 and various other in Irssi SILC Client.
2402 Added `responder' boolean argument to the functions
2403 silc_client_add_private_message_key[_ske] to indicate when
2404 the key is added as responder or initiator of the key
2407 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2409 * Removed the silc_ske_check_version function and created
2410 a SilcSKECheckVersion callback. Added also a function
2411 silc_ske_set_callbacks that is now used to set all SKE
2412 callbacks. The callback functions are not given to
2413 the SKE functions anymore, but this function is used to
2416 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2418 * Added `silc_version' argument to the silc_client_alloc
2419 to define the version of the application for the library.
2420 The library will use the version string to compare it
2421 against the remote host's (usually a server) version
2422 string. Affected file lib/silcclient/silcapi.h
2424 * Added the KE protocol context to Key Agreement context
2425 in client library so that we can abort the SKE if it
2426 is in process when we get timeout. Affected file is
2427 lib/silcclient/client_keyagr.c.
2429 * Do not resolve the client ID forever if it returns in the
2430 first time that such client does not exist. This was done
2431 for example with private message. Affected file is
2432 lib/silcclient/client_prvmsg.c.
2434 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Do not add regex.h for WIN32. The affected file
2437 includes/silcincludes.h.
2439 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2440 not work yet 100%. It generates the DLL's automatically
2441 when compiling with --with-win32 under cygwin.
2443 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * lib/contrib/regex.c is not compiled on WIN32.
2447 * Added silc_net_get_socket_opt function to the
2448 lib/silcutil/silcnet.h.
2450 * Added includes/silcwin32.h for WIN32 specific includes
2453 * Do not use ptime structure or any of the posix process
2454 functions on WIN32 in lib/silccrypt/silrng.c.
2456 * Added silc_gettimeofday to provide generic function
2457 for struct timeval on all platforms. Added the function
2458 to lib/silcutil/silcutil.h.
2460 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2462 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2463 library as they clearly belong there. As a plus side we
2464 can make the actual socket connection routines platform
2467 Added also new generic function silc_socket_read and
2468 silc_socket_write (that used to be silc_packet_[read/write].
2469 The implementation of these are platform specific.
2471 * Added WIN32 specific routines of silc_socket_[read/write]
2472 to lib/silcutil/win32/silcwin32sockconn.c.
2474 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Added preliminary support for native WIN32 compilation under
2477 cygwin (using the -mno-cygwin option for GCC) to the
2478 ./configure.in.pre. The --with-win32 now prepares the
2479 compilation for native WIN32.
2481 * Rewrote the SILC Scheduler interface in the file
2482 lib/silcutil/silcschedule.h. The scheduler is now context
2483 based and does not have anymore any global static scheduler.
2484 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2485 and created lib/silcutil/win32 directory for WIN32 based
2488 * Added Unix specific network routines to the
2489 lib/silcutil/unix/silcunixnet.c and the old
2490 lib/silcutil/silcnet.c includes now only generic routines.
2492 Added WIN32 specific network routines to the
2493 lib/silcutil/win32/silcwin32net.c.
2495 * Added Unix specific utility functions from the
2496 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2498 * Added WIN32 SILC Scheduler to the file
2499 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2502 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Do not handle JOIN notify in the server if the target client
2505 is not registered (idata->registered == FALSE). The affected
2506 file is silcd/packet_receive.c.
2508 * Update the nickrec->founder in event_cumode in the Irssi SILC
2509 client. Affected file irssi/src/silc/core/silc-channels.c.
2511 * Fixed the CUMODE_CHANGE notify handling in the server when
2512 server and router are announcing their clients on channels.
2513 Now the mode changes are saved and notified correctly. The
2514 affected file is /silcd/packet_receive.c.
2516 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2517 They really did not replace the cache entry in the ID Cache.
2518 Now they do that. Affected file silcd/idlist.c.
2520 * Fixed the KICK notify handling in the Irssi SILC client to
2521 update the channel records so that the kicked client does not
2522 appear to be on the channel. The affected file is
2523 irssi/src/silc/core/silc-channels.c.
2525 * Always update the conn->current_channel when executing command
2526 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2528 * Fixed the KILL notify handling in Irssi SILC client to remove
2529 the killed client on all channels.
2531 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2533 * Fixed the silc_parse_command_line to remove extra spaces
2534 from the start and end of the arguments. Affected file is
2535 lib/silcutil/silcutil.c.
2537 * Cancel and free any active protocol in the function
2538 silc_server_close_connection. Affected file silcd/server.c.
2540 * Cancel and free any active protocol in the function
2541 silc_client_close_connction. Affected file is
2542 lib/silcclient/client.c.
2544 * Do not execute the KILL command for clients that are in
2545 history (ie. they are not in the network). Affected file is
2548 * Fixed KILL notify handling, client does not crash anymore.
2549 Affected file irssi/src/silc/core/silc-channels.c.
2551 * Reduced the default packet buffer size from 2048 to 1024 in
2552 lib/silccore/silcpacket.c.
2554 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2555 counter to the SKE context that is incresed when the SKE library
2556 performs async operation outside the library. If the outside
2557 process frees the SKE context and FREED status will be set
2558 and the library will detect after the sync operation that the
2559 libary is freed. The affected files are
2560 lib/silcske/silcske[_status].[ch].
2562 * Resolve the client entry information in the function
2563 silc_client_channel_message to assure that NULL pointer is not
2564 passed as client entry to the application. */
2566 * Fixed the task timeout calculation to assure that there is
2567 never negative timeouts. The affected file is
2568 lib/silcutil/silcschedule.c.
2570 * Fixed the channel user mode notification sending in server.
2571 It was sent point-to-point to the router (or to server by router)
2572 but it needs to be destined to a channel. The routines now
2573 supports sending the channel user mode notifys to the channels
2574 when announcing clients and channels. Affected files are
2575 silcd/server.c and silcd/packet_receive.c.
2577 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2578 It did not actually replace the old channel entry in the cache.
2579 Affected file lib/silcclient/client_notify.c.
2581 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Fixed a possible crash in silc_packet_send_prepare. It now
2584 assures always that there is enough space in the buffer and
2585 at the tail area of the buffer (for MAC).
2587 Fixed the inbound buffer reallocation in silc_packet_read.
2588 It was old code and did not handle the reallocation correctly.
2591 The affected file is lib/silccore/silcpacket.c.
2593 * Fixed buffer overflow in silc_parse_nickname in the file
2594 lib/silcutil/silcutil.c.
2596 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2598 * make install generates new server keys only if there is not
2601 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2603 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2604 Added check that if the NOREPLY is set then we will not send
2605 the away message. This avoids infinite loop of away messages
2606 if both clients are away. The affected file is
2607 lib/silcclient/client_prvmsg.c.
2609 * Fixed client crash if /NICK was given without arguments.
2610 Affected file lib/silcclient/command.c.
2612 * Server does not send the invite list in INVITE command back
2613 to the client if the list was not altered. Added this notion
2614 to the protocol spec as well. Affected file silcd/command.c.
2616 Fixed possible crash in INVITE command by checking the
2617 value of silc_server_get_client_route command.
2619 * Fixed the INVITE notify type handling. The arguments are now
2620 taken in correct order and client does not crash. The affected
2621 file is irssi/src/silc/core/silc-channels.c.
2623 Removed the "Inviting xxx to channel" message from the
2624 client library away and let the application handle it.
2625 Affected file lib/silcclient/command.c. Added that message
2626 to Irssi SILC client's message formats.
2628 * Fixed CMODE command crash in client. It now checks the
2629 amount of arguments correctly and does not crash. The affected
2630 file is lib/silcclient/command.c.
2632 * Do not create new channel automatically in silc_channels_join
2633 but check whether the channel by that name already exists.
2634 Affected file irssi/silc/core/silc-channels.c.
2636 * Do not send the SERVER_SIGNOFF to router if the disconnected
2637 entity was the router. Affected file silcd/server.c.
2639 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2640 SILC client as it was missing from there.
2642 Added the handling of the KICK notify to the Irssi SILC client
2643 as it was missing. Added "you have been kicked" message to
2644 Irssi SILC client's message modules formats.
2646 Added the handing of the KILL notify to the Irssi SILC client
2647 as it was missing. Added the kill message module formats
2650 The affected file is irssi/src/silc/core/silc-channels.c.
2652 * The router did not save the channel mode the server announced.
2653 Affected file silcd/packet_receive.c.
2655 * Fixed a possible crash in INFO command in server. If the
2656 server did not provide the server info it crashed. Affected
2657 file silcd/command.c.
2659 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Fixed the GETKEY command in the server to check also the
2662 global list. Otherwise the GETKEY would not work correctly
2663 in normal SILC server. Affected file silcd/command.c.
2665 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2667 * Fixed GETKEY crash, it crashed if the command did not succseed.
2669 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2671 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2672 is now real and not just an macro interface to GMP.
2674 Removed the entire GMP from the source tree and imported new
2675 NSS MPI library instead. Reason for removing GMP is that it is
2676 extremely large and compiles extremely slow. The NSS MPI
2677 is only a few files and compiles in less than 10 seconds.
2678 The speed is also about the same as GMP. The MPI is imported
2679 to lib/silcmath/mpi.
2681 If the system has GMP installed we will still use the GMP.
2682 If it is not then the NSS MPI will be compiled.
2684 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2686 * Merged a long nickname (127 characters long) crash bugfix from
2687 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2689 * Merged a freed memory reference bugfix from Irssi CVS tree.
2690 Affected file irssi/src/core/commands.c.
2692 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2694 * Added the server's public key sving and verification to the
2695 server when performing the SKE. This was missing and the
2696 remote server's (or router's) public key was accepted without
2697 checking whether we have it previously or trust it at all.
2698 Affected file silcd/protocol.c.
2700 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Check in the silc_server_timeout_remote if protocol is active
2703 and make sure that the protocol's final callback is called so
2704 that all memory if freed. Affected file silcd/server.c.
2706 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2708 * silc_server_whois_send_reply crashed the server if the nickname
2709 was 127 characters long. Affected file silcd/command.c.
2711 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2713 * Added sanity check to the silc_server_new_client. If the hostname
2714 is provided inside username then check that the provided hostname
2715 really is the same as the resolved one. If the hostname was not
2716 resolved then check it from the public key. Affected file is
2717 silcd/packet_receive.c.
2719 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2720 if the server disconnected us and the connection is not valid
2721 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2723 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2724 the library to the lib/silcutil/silcutil.[ch].
2726 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Close log file after open. Affected file
2729 lib/silcutil/silclog.c.
2731 * Check whether sock == NULL in silc_client_send_packet and return
2732 if it is. Affected file lib/silcclient/silcclient.c.
2734 * Check rec->entry == NULL in the Irssi SILC Client before
2735 sending the channel message. Affecte file is
2736 irssi/src/silc/core/silc-servers.c.
2738 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2740 * Merged a splitted window bugfix from Irssi CVS tree. The
2741 affected file is irssi/src/fe-text/textbuffer-view.c.
2743 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2744 It did not print nickname.
2746 * Improved the distributions system a bit.
2748 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2750 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2751 irssi/src/fe-text/gui-window.c.
2753 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2754 to in-active server. The affected file is
2755 irssi/src/silc/core/client_ops.c.
2757 * Resolve the client in USERS command reply if the entry does
2758 not have username resolved. The affected file is
2759 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2760 command to WHOIS command to really resolve stuff. The USERS
2761 is not used any more in any critical section so WHOIS can
2762 be used even though it might be slower than IDENTIFY.
2764 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2767 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Changed the protocol API a bit more consistent in the
2770 lib/silccore/silcprotocol.[ch].
2772 * Changed the following headers to ROBODoc format:
2774 lib/silccore/silcpayload.h
2775 lib/silccore/silcprotocol.h
2776 lib/silccore/silcsockconn.h
2778 All core library headers are now formatted.
2780 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2782 * Fixed a bug in Irssi SILC client; do not show that you are
2783 server/router operator if you really are not. Affected file is
2784 irssi/src/silc/core/client_ops.c.
2786 * Renamed silc_command_free_payload to silc_command_payload_free.
2787 Affected file lib/silccore/silccommand.h
2789 * Added silcmath.h to include the prototoypes of various routines
2790 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2793 * Changed the following headers to ROBODoc format:
2795 lib/silccore/silcchannel.h
2796 lib/silccore/silccommand.h
2797 lib/silccore/silcid.h
2798 lib/silccore/silcidcache.h
2799 lib/silccore/silcmode.h
2800 lib/silccore/silcnotify.h
2801 lib/silccore/silcpacket.h
2802 lib/silcmath/silcmath.h
2804 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2806 * Added checking to the server code not to start the server if
2807 ciphers and stuff are not configured properly. Affected files
2808 silcd/serverconfig.[h] and silcd/server.c.
2810 * Changed the layout of the header files of the public interfaces
2811 in the SILC libraries. The new layout supports ROBODoc
2812 documentation tool (and some others) so that it is easy to create
2813 a library reference manual. All the other headers and source
2814 code must still follow the CodingStyle document. Also source
2815 code must not include these ROBODoc stuffs, only the headers.
2816 Furthermore, all public interface headers must now be named
2817 by using `silc' prefix, example: silcapi.h, silccipher.h.
2818 Some files were renamed due to this. All the other headers
2819 must not be used as public interfaces. I will update the
2820 CodingStyle document later. Changed following headers, so far:
2822 lib/silcclient/silcapi.h
2823 lib/silccore/silcauth.h
2824 lib/silccore/silcprivate.h
2825 lib/silccrypt/silcdh.h
2827 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Removed silc_client_packet_send_flush from the client library
2832 as it is not needed. Affected file lib/silcclient/client.[ch].
2834 * Added printing of message of unresolved authentication method
2835 to the Irssi SILC client. Added it to the module formats.
2836 Removed the same message from the client library.
2838 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2840 * Added new distribution feature, DISTLABEL. Every distribution
2841 can define own preprocessor label that can be used in the
2842 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2843 file distributions, acconfig.h.pre and prepare.
2845 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Added Makefile.defines_int to include the actual definitions
2848 for Makefile.defines.in. Tested the new distribution system,
2849 created distributions and tested installation.
2851 * Added AWAY message printing to the Irssi SILC client. Added
2852 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2854 * Added SCONNECT command to call the SILC's CONNECT command.
2855 Cannot use CONNECT directly since Irssi uses that internally.
2856 Affected file irssi/src/silc/core/silc-servers.c.
2858 Added ACTION local command. It is same as ME command but takes
2859 the channel as mandatory argument.
2861 Rewrote some of the Irssi's help files to suite for SILC
2864 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * Added Makefile.defines[.in] that should for now on be included
2867 in all Makefile.am file in the source tree. That file includes
2868 all common compilation definitions for SILC source tree.
2870 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Minor changes to the ./prepare script to change the package
2873 name according the distribution name to the configure.in.
2875 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2877 * Created new distribution system. Added file `distributions'
2878 that defines all the distributions that can be created out of
2879 the SILC source tree. The ./prepare script now reads that
2880 file to determine how to prepare the distributions. The
2881 first argument to the ./prepare is the name of the distribution
2882 and second is the version of the distribution. If given
2883 without arguments it creates the default (toolkit) distribution
2884 with the default version (defined in ./prepare).
2886 All Makefile.am files that are subject to the distributions
2887 are now named as Makefile.am.pre. These are ./Makefile.am
2888 and lib/Makefile.am. Others may be changed later.
2890 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Added invite list, ban list, some key management and connection
2893 error message printing to module formats in the Irssi SILC client.
2895 * Added new silc_client_set_away_message to set the away message
2896 that is back to the person who sent private message. The
2897 affected file lib/silcclient/silcapi.h and the
2898 lib/silcclient/client_prvmsg.c.
2900 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Fixed the private message sending in the Irssi SILC client,
2903 added local command KEY to the Irssi SILC client.
2905 Added key management and key agreement message formats to the
2906 irssi/src/fe-common/silc/module-formats.[ch].
2908 Added USERS (alias WHO) printing, server/router operator
2909 indication and LIST command printing to the module formats.
2911 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2913 * Fixed channel joining notify handling, cumode notify handling
2914 from Irssi SILC client.
2916 * Added SILC specific module-formats to the Irssi SILC client so
2917 that SILC specific message hilighting, colors etc is possible.
2918 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2920 Added channel mode, channel user mode, actions, notices,
2921 whois and whowas printing to the the module-formats.c.
2923 * Fixed a bug in channel deletion in the server. The channel
2924 is not left to the cache even if the channel founder auth mode
2925 is set when there are no users anymore on the channel. Affected
2926 file silcd/server.c.
2928 * The silc_net_localhost now resolves the entire hostname including
2929 the domain name. Affected file lib/silcutil/silcnet.c.
2931 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * Changed the ask_passphrase client operation to be ascynchronous.
2934 It has now a completion callback and a context that the
2935 application must call after it has got the passphrase from
2936 the user. Affected files lib/silcclient/silcapi.h,
2937 lib/silcclient/protocol.c, lib/silcclient/command.c and
2940 Added SilcAskPassphrase callback that the application calls
2941 to deliver the passphrase to the library.
2943 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2944 The public key verification and especially a certificate
2945 verification is asynchronous procedure.
2947 Added new SILC_SKE_STATUS_PENDING status to indicate the
2948 request is pending and a callback will be called to finalize
2951 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2952 indicate that remote end did not send its public key (or
2953 certificate), even though we require it. Added check for this
2954 condition in the SKE. This was a security bug, now fixed.
2956 Defined new SilcSKEVerifyCbCompletion callback that is called
2957 when the verification process is completed.
2959 The affected files lib/silcske/silcske_status.h and
2960 lib/silcske/silcske.[ch].
2962 * Changed the verify_public_key client operation to be async
2963 as well. Defined SilcVerifyPublicKey callback that is used to
2964 indicate the success of the public key verification process.
2966 Changed the server and client to use the new async client
2969 * Changed the Irssi SILC client's internal scheduler to be called
2970 twice as many times as it used to be. As a result the client
2971 should be a bit faster now. Affected file is
2972 irssi/src/silc/core/silc-core.c.
2974 * Added support to Irssi SILC client of asynchronous public key
2975 verification and passphrase inquiry. Affected file is
2976 irssi/src/silc/core/silc-core.c.
2978 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Do not say "You have left channel %s" in client library.
2981 Moved it to the application. Affected files are
2982 lib/silcclient/command.c and silc/client_ops.c.
2984 * Fixed silc_client_get_clients. Command context was not
2985 duplicated and was freed memory in the callback. Affected
2986 file lib/silcclient/idlist.c.
2988 * Do not say "you are now talking..." on JOIN command in the
2989 client library. The appliation must handle it.
2991 * Do not say ".. changed topic to" in command reply in the
2992 client libary. The application must handle it.
2994 * Fixed TOPIC command sending in the client library.
2996 * Fixed a memory leak in silc_client_command_free in the file
2997 lib/silcclient/command.c.
2999 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Imported a modified version of Irssi client to the source tree.
3002 The Irssi will be used to create a new client called
3003 Irssi SILC. Imported to irssi/.
3005 Added silc_core_init_finish function to the Irssi. Affected
3006 file irssi/configure.in.
3008 A lot changes in the Makefile.ams around the irssi tree.
3010 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Do not rehash if the new size is same as the old size of the
3013 hash table, in the silc_hash_table_rehash*. The affected file
3014 lib/silcutil/silchashtable.c.
3016 * Replaced hash_table_del_by_context calls from the server
3017 (when channel->user_list and client->channels) to the
3018 hash_table_del as it is sufficient and faster.
3020 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3022 * Added silc_hash_table_list, silc_hash_table_get and the
3023 SilcHashTableList structure to provide an alternative way to
3024 traverse the hash table. The affected files are
3025 lib/silcutil/silchashtable.[ch].
3027 * Changed the server's idlist routines to use the hash table
3028 routines to optimize the code.
3030 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3032 * Replaced the client entry's `channel' list and channel entry's
3033 `user_list' list to hash tables for optimized lookup. Changed
3034 the code to use the hash table interface around the code.
3035 Affected file lib/silcd/idlist.[ch].
3037 * Added `auto_rehash' boolean argument to the function
3038 silc_hash_table_alloc to indicate whether the hash table should
3039 auto-rehash when it thinks is appropriate time. It will
3040 increase the hash table size if the there is twice as much
3041 entries in the table than the size of the table, and will
3042 decrease the size if there are twice as less entries than
3043 the size of the table.
3045 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3047 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3049 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * silc_idcache_purge_by_context deletes the entry now by context
3052 as it is supposed to do. Affected file lib/silccore/idcache.c.
3054 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3055 client is not anymore valid (WHOWAS givens the info) and not
3056 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3058 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3060 * Removed the `data' and `data_len' arguments from the ID Cache
3061 interfaces and added `name' argument. ID Cache does not handle
3062 anymore the binary data only a names associated with given ID.
3064 * When hashing a Client ID with silc_hash_id the entire ID is
3065 not hashed anymore, instead only the hash of the Client ID is
3066 hashed. This way we can access the Client ID from the cache
3067 with Client ID but with the hash of the ID (which is a hash of
3068 the nickname) as well without any difference in performance.
3070 Added also silc_idcache_find_by_id_one_ext to do one on one
3071 searching when we have the actual ID. Added also function
3072 silc_hash_client_id_compare. The affected files are
3073 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3075 * When hashing the name associated with a ID it is always done
3076 in lowercase. This way we can access the cache without worrying
3077 about case-sensitivity, even though, for example nicknames are
3080 * Fixed a bug in server with channel message sending. It put
3081 wrong ID type as destination ID. The affected file
3082 silcd/packet_send.c.
3084 * silc_idcache_del_by_context now deletes from all hash tables
3085 by context. Affected file lib/silccore/idcache.c.
3087 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3089 * Changed the client library to use the new ID Cache interface.
3090 Changes around the source tree.
3092 * Added silc_hash_table_rehash_ext to rehash with specific
3093 hash function. Affected file lib/silcutil/silchashtable.[ch].
3095 * Added silc_hash_string_compare to compare two strings in the
3096 hash table. Affected file lib/silcutil/silcutil.[ch].
3098 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3100 * Added new function silc_idcache_del_by_context into the
3101 lib/silccore/idcache.[ch].
3103 * Changed the server's ID list routines to use the new ID Cache
3104 interface. Changes around the source tree.
3106 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Added silc_hash_table_del[_by_context]_ext functions in to the
3109 lib/silcutil/silchashtable.[ch].
3111 Removed silc_hash_table_find_all* routines and added new
3112 silc_hash_table_find_foreach to replace them.
3114 Added silc_hash_table_replace_ext function as extended
3115 replacing function. Separated the simple hash table interface
3116 from the extended hash table interface in the file
3117 lib/silcutil/silchashtable.h.
3119 * Fixed minor bugs and changed it to use some of the new
3120 hash table functions in lib/silccore/idcache.c
3122 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Added new function silc_hash_table_find_all to return all keys
3125 in the hash table by the specified key. As the hash table is
3126 collision resistant it also makes it possible to have several
3127 duplicate keys in the hash table. This function may be used to
3128 find all of the keys from the hash.
3130 Added user_context arguments to the SilcHashFunction,
3131 SilcHashCompare and SilcHashDestructor to deliver user specified
3134 Added new fuctions silc_hash_table_find[_all]_ext to do
3135 extended lookup with specified hash and compare functions and
3136 specified user contexts.
3138 Added new function silc_hash_table_add_ext to add the key
3139 with specified hash function and user context.
3141 Added new function silc_hash_table_foreach to traverse all
3142 entrys in the hash table. Added SilcHashForeach callback
3145 Added new function silc_hash_table_del_by_context to delete
3146 the entry only if the context associated with the key matches.
3148 Affected files are lib/silcutil/silchashtable.[ch].
3150 * Removed silc_hash_[server/client/channel]_id and added just
3151 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3152 silc_hash_id_compare to compare two ID's using as the hash table
3153 comparison function. Added also silc_hash_data to hash
3154 binary data and silc_hash_data_compare to compare it.
3156 * Removed silc_idlist_find_client_by_hash as it is not needed
3157 anymore. Affected file silcd/idlist.[ch].
3159 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3160 to use internally the SilcHashTable. The new ID Cache is a lot
3161 faster than the old one. Some of the ID Cache interface was also
3162 rewritten and obsolete and stupid functions were removed.
3164 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Added entry_count field to the SilcHashTable to keep the number
3167 of the entries in the table. Implemented the function
3168 silc_hash_table_rehash. Added new function
3169 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3171 Fixed a minor bug in silc_hash_table_free.
3173 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3174 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3175 into the lib/silcutil/silcutil.[ch].
3177 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3179 * Implemented a collision resistant hash table into the
3180 lib/silcutil/silchashtable[ch]. See the header and the source
3181 for the SilcHashTable API.
3183 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3185 * Merged dotconf version 1.0.2 into lib/dotconf.
3187 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3189 * Do not compile anything in lib/silcsim/* if the SIM support
3190 is not enabled. The tree should now compile without problems
3193 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Compiled the SILC under cygwin. Compiled and tested briefly
3196 without problems. More tests needed. The SIMs didn't compile
3199 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3201 * Fixed possible crash in silc_get_username in the
3202 lib/silcutil/silcutil.c.
3204 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Fixed a va_arg in silc/client_ops.c.
3208 * Oops, RC5 routines were named AES and caused some problems
3209 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3211 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Added new SilcIDIP structure into the lib/silccore/id.h and
3214 replaced the old `ip' fields from all SILC ID's to that type.
3215 This is a step towards IPv6 support.
3217 The silc_id_get_len takes now the ID as an extra argument.
3218 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3219 both IPv4 and IPv6 based ID's.
3221 The affected files are lib/silccore/id.[ch] and other files
3222 around the tree using these routines.
3224 * Removed the ID length arguments in server from various
3225 silc_server_send_notify_* routines -> they are not needed
3228 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3230 * Fixed memory leak in silc_encode_pem_file in the file
3231 lib/silcutil/silcutil.c.
3233 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Check minor version as well in the SKE. Affected files are
3236 silcd/protocol.c and lib/silcclient/protocol.c.
3238 * Added --identifier option to the server so that an identifier
3239 can be when creating the public key for the server. Affected
3240 file is silcd/silcd.c.
3242 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3243 lib/silccrypt/silcpkcs.c.
3245 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Register default ciphers and stuff when using -C option with
3248 the server. Affected file sildc/silcd.c.
3250 * Put back the servers public key filename format, it is better
3251 than the new one. For now, the client keys are saved with the
3252 new filename format. The affected file silc/client_ops.c.
3254 * Implemented the Cipher API for the rest of the ciphers that
3255 did not implement it or implemented it the wrong way.
3257 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Register default ciphers and stuff when using the -S option
3260 in the client. Affected file silc/silc.c. Same also when
3261 creating new key pair with -C option.
3263 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Fixed the silc_verify_public_key client operation function to
3266 save the public keys differently. The fingerprint is now
3267 used as filename and not the hostname. This way also the
3268 client keys are saved uniquely and not with hostnames. The
3269 affected file is silc/client_ops.c.
3271 * Trimmed the silc_hash_fingerprint function to remove extra
3272 whitespaces from the end of the fingerprint. The affected
3273 file is lib/silccrypt/silchash.c.
3277 * Added silc_cipher_register_default function to register all
3278 default ciphers. It can be used when configuration files
3279 does not exist and the application does not want any specific
3280 ciphers in any specific order.
3282 The SilcDList is now used as silc_cipher_list dynamically
3283 allocated cipher list. Removed the static list all together
3284 and now all ciphers must be allocated to the dynamic list.
3285 The silc_cipher_alloc routine was changed to check only the
3288 All silc_cipher_* routines that used to return int returns
3291 The affected files lib/silccrypt/silccrypt.[ch].
3293 * The same thing was done to silc_hash_* as for silc_cipher_*
3294 routines. Affected files lib/silccrypt/silchash.[ch].
3296 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3297 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3298 Added also silc_pkcs_[un]register[_default] functions.
3299 Removed the data_context from the PKCS API.
3301 * Added silc_hmac_register_default function to register default
3302 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3303 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3304 to unregister all hmacs at once.
3306 * Register the default ciphers, hash functions, PKCSs and HMACs
3307 if client's configuration file does not exist. The affected
3310 * The client did not load the hash functions from the SIM
3311 modules at all. Added support for this. Affected file is
3312 silc/clientconfig.c.
3314 * When decoding public key with silc_pkcs_public_key_decode, check
3315 the supported algorithm only if PKCS are registered. Affected
3316 file lib/silccrypt/silcpkcs.c. The same was done with the
3317 silc_pkcs_private_key_decode.
3319 * Fixed the SILC List routines to keep the list always in order.
3320 It used to change the list's order when traversing the list but
3321 not it preserves the order. Affected file lib/trq/silclist.h.
3323 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Added the client library to use the SilcSocketConnection's
3326 reference counter (by silc_socket_dup) to prevent the bug that
3327 the socket object may be freed underneath async operation.
3329 * The name resolv library checking fixes in the configure.in.pre.
3332 * Created new version of the protocol drafts for future
3333 development. The -03 drafts are the ones that will be changed
3334 in the trunk now and the -02 will remain as they are.
3336 * Send list of CUMODE notifys to the router when announcing
3337 the channel users to the router. Affected file silcd/server.c.
3338 If the router receiving channel founder CUMODE for a channel
3339 that already has channel founder it will send CUMODE notify
3340 to the sender to remove the channel founder rights from the
3341 announced client. Affected file silcd/packet_receive.c.
3343 * The CUMODE notify may now use Server ID as well as the entity
3344 who changes the mode. Updated protocool specs.
3346 * Updated INSTALL and README files.
3348 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * New web pages in the http://silc.pspt.fi. The pages was
3355 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Implemented the [DenyConnectin] config section in the server.
3358 Added silc_server_config_denied_conn to check whether incoming
3359 connection is denied. Affected file silcd/serverconfig.[ch].
3361 * Do not check the ports when checking the incoming configuration
3362 data if the port is 0, meaning any. Affected file is
3363 silcd/serverconfig.c.
3365 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Fixed buffer overflow in silc_string_compare in the file
3368 lib/silcutil/silcutil.c.
3370 * Fixed double free in silc_server_command_leave in the file
3373 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Fixed the version checking in the server. Affected file is
3378 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Fixed the configuration data fetching when accepting new
3381 connections in the server. Affected file silcd/server.c.
3383 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Added `sender_entry' argument to the function
3386 silc_server_packet_relay_to_channel so that we can check
3387 whether some destination actually belongs to the same route
3388 the sender belongs (ie, we must not resend the packet to the
3389 sender). Affected file silcd/packet_send.[ch].
3391 * Added `servername' field to the SilcClientEntry in the server
3392 to hold the name of the server where client is from. Affected
3393 file is silcd/idlist.h.
3395 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Moved the channel message encrypting in the router betwen
3398 router connections from silc_server_channel_message to the
3399 silc_server_packet_relay_to_channel since we want to check
3400 whether we have anybody channel before encrypting anything.
3401 Affected files silcd/packet_[receive/send].c.
3403 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Fixed the [AdminConnection] server config section to support
3406 multiple entries. Affected file silcd/serverconfig.c.
3408 * Added support into the server to check the validity of the
3409 incoming connection before executing any KE or authentication
3412 * The connection configuration is now saved to the KE and
3413 connection auth protocol contexts and not fetched anymore in
3414 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3416 * The local hosts listenning address and port is also resolved
3417 now when starting the server. We want to have the socket object
3418 to include the real address and port for the listener. Added
3419 new function silc_net_check_local_by_sock into the files
3420 lib/silcutil/silcnet.[ch].
3422 * Fixed a broadcast bug in server -> do not broadcast if we
3425 * Fixed a routing bug. Do not route broadcast packets ever.
3426 Broadcast packets must be processed always and not routed since
3427 they may be destined to some other host than yourself and thus
3428 would get routed without no good reason. Affected file is
3431 * Added function silc_server_config_is_primary_route to check
3432 whether primary router connection has been configured (a router
3433 configuration that we are initiating). If there is not, we
3434 will assume that there is only two routers in the SILC network
3435 and we will use the incoming router connection as our primary
3436 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3438 * Changed the order of the broadcasting. Broadcast _after_ the
3439 packet has been processed not before. Affected file is
3442 * Fixed a [ClientConnection] parsing bug. The port was never
3443 parsed correctly thus resulting to port 0. Affected file
3444 silcd/serverconfig.c.
3446 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3447 argument and did not set the broadcast packet flag. Affected
3448 file silcd/packet_send.c. Fixed same bug in the function
3449 silc_server_send_notify as well.
3451 * If we receive NEW_ID packet for our own ID in the server, ignore
3454 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Removed the nickname from the Private Message Payload.
3459 Updated the code and the protocol specs.
3461 * Updated protocol specs for submitting to the IETF.
3463 * Tweaked the Random Number Generator a bit. Affected file
3464 lib/silccrypt/silcrng.c. Exported a new function
3465 silc_rng_[global]_add_noise which can be used to add more
3468 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Do not parse packets with different timeout when protocol
3471 is active -> may cause problem with rekey. Affected file
3474 * When server receives signoff notify it must not create
3475 new channel key if the client is on any channels since the
3476 sender of the signoff notify will create it.
3478 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Added printing of error messages during SKE protocol from the
3481 failure packet sent by server during SKE. Affected file
3484 * Removed the client's failure_callback handling with timeout
3485 and handle it immediately when received.
3487 * The SKE library returned wrong type in SUCCESS and FAILURE
3488 packets. They must be 32 bit MSB not 16 bit MSB.
3490 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3492 * Ok, rewrote the logic of the re-key and now it seems to work.
3493 I tested it on high traffic with frequent re-keys without
3494 problems. Added hmac_receive (and renamed hmac to hmac_send)
3495 in SilcClientConnection in lib/silcclient/client.h and
3496 in SilcIDListData in silcd/idlist.h. Also, removed the
3497 SilcPacketParserContext's cipher and hmac fields as they are
3498 not needed anymore and actually caused some problems when
3499 the ciphers and hmac's changed underneath the packet parser.
3501 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * If re-key protocol is active then process the incoming packets
3504 synchronously since we must assure that icoming packets encrypted
3505 with the old key is processed before the new keys is set to
3506 use. This is true other packets than for REKEY packets.
3507 Affected file silcd/server.c. The same was done to client library
3508 as well, affected file lib/silcclient/client.c.
3510 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3512 * Fixed bug in client and server to accept the force send if
3513 the packet is send from silc_[server/client]_packet_process
3514 function. Otherwise the packets are never delivered, oops.
3516 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Disable force sending of packets when REKEY protocol is active.
3519 We must assure that no packet is sent directly when rekey is
3520 performed. All packets must be sent through packet queue.
3521 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3522 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3523 function is silc_[server/client]_packet_send_real to check
3526 * Replaced the SIM paths from example config files to
3527 /usr/local/modules. Also, make install creates now
3528 /usr/local/silc/logs directory to hold all the SILC server
3531 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3533 * Made the configure.in.pre work on Solaris. Patch by salo.
3535 * Made all ciphers compatible with non-x86 machines. Defined
3536 CBC mode macros into lib/silccrypt/ciphers_def.h.
3538 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * Fixed the make install.
3542 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * When MAC computation fails the silc_packet_decrypt returned 0
3545 even though it was supposed to return -1. Fixed this. The
3546 affected file is lib/silccore/silcpacket.c.
3548 * Do not replace the config files in /etc/silc (in make install)
3549 if they already exist. Affected file ./Makefile.am.
3551 * Do not send re-key packets immediately but through packet queue.
3552 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3554 * Changed silc_net_check_host_by_sock to return FALSE if the
3555 IP/DNS could not be resolved. Though, it returns the IP address
3556 now even if it could not resolve it (but returns also FALSE).
3557 Affected file lib/silcutil/silcnet.[ch].
3559 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Added silc_pkcs_decode_identifier to decode the public key's
3562 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3563 Added also silc_pkcs_free_identifier. Added also new context
3564 SilcPublicKeyIdentifier.
3566 * Added -S option to the silc client. It is used to dump the
3567 contents of the specified public key file.
3569 * Changed the PKCS api to return the public key length when
3570 setting the public key.
3572 * Fixed a fatal bug in the public and private key file loading.
3573 Affected file lib/silccrypt/silcpkcs.c.
3575 * Execute the packet parsing for client with zero (0) timeout
3576 if the protocol is active. Affected file silcd/server.c.
3578 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Made the key generation options to the silcd program. Added
3581 -C option, equivalent to client's option.
3583 * Added new [ServerKeys] config section to the server. It
3584 configures the server's public and private key.
3586 * Defined generic Public Key Payload into the protocol
3587 specification to send specific type of public keys and
3590 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3591 public key or certificate.
3593 * Implemented the GETKEY command to the server and to the
3594 client library and on user interface.
3596 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Made preliminary `make install' work.

3628 lib/silcclient/client.h.
3632 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Do not ask whether user wants to use the negotiated private key
3635 for private messages, just use it. Affected file is
3636 silc/local_command.c.
3638 * Added `send_enc_key' and `enc_key_len' fields to the
3639 SilcIDListData structure since they are needed in the re-key
3640 phase. Affected file is silcd/idlist.[ch].

3659 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3660 int64 of at least the xintXX size. If void * is less that 4
3661 bytes uint32 * will be used. Defined bool as boolean.
3663 * Changed _ALL_ unsigned long and unsigned int to uint32,
3664 unsgined short to uint16 in the source tree.
3666 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3667 not handle clients that has entry->data.registered == FALSE.
3668 They are not in the network anymore. Affected file is
3671 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Implemented the sending of the SERVER_SIGNOFF notify in the
3674 server. Affected file is silcd/server.c.
3676 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

3685 implemnted the printing of the SERVER_SIGNOFF info to the
3686 application. Affected file silc/client_ops.c.
3688 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3689 if the deleting was successful. Affected file silcd/idlist.[ch].
3691 * Added support for public key authentication in the connection
3692 authentication protocol in the client library. Affected file
3693 lib/silcclient/protocol.c.
3695 * Changed the server's silc_idlist_get_clients_by_* interface
3696 to support already allocated array so that new entries may be
3697 added to pre-allocated array. Affected file silcd/idlist.[ch].
3698 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3699 and command replies.
3701 * All command reply functions in the server now calls the
3702 pending command callback even if error occured. This way the
3703 error will be delivered to the client as well. Affected files
3704 silcd/command.c and silcd/command_reply.c.
3706 * Fixed INFO command to return local server's info if no server
3707 was provided. Affected file lib/silcclient/command.c.
3709 * Removed RESTART command for good. Updated the code and the

3721 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3725 * Added channel key re-key support. The re-key is perfomed
3726 only by the router and is done once in an hour. Added `rekey'
3727 field to the SilcChannelEntry in the server. Affected files
3728 silcd/server.c and silcd/idlist.h.
3730 * Added silc_task_unregister_by_context into the file
3731 lib/silcutil/silctask.[ch].
3733 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3735 * Added SILC_UMODE_GONE mode to indicate when the client is not
3736 present in the SILC network. Added also support to the local
3737 command AWAY that will set this mode. Added support of showing
3738 "xxx is gone" in WHOIS command. The USERS command shows the
3739 gone status as well.
3741 * Fixed setting server and router operator privileges in the
3742 server's UMODE command. Affected file silcd/command.c.
3744 * Merged the SKE KE1 and KE2 payloads into one payload. The
3745 new KE payload is equivalent to the old KE2 payload.
3747 Cleaned up the SKE Start Payload parsing. It now uses the
3748 simple buffer unformatting to do the parsing. A lot faster
3751 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3752 to the SKE that is used to indicate whether both of the SKE
3753 parties should perform authentication. By default only the
3754 responder performs authentication. By setting this flag also
3755 the initiator must do authentication. By default it is unset
3756 since in normal SKE case, client to server connection, only
3757 the responder should do authentication. When doing SKE between
3758 two clients both should perform authentication. Updated the
3759 code and the protocol specs.
3761 * A little fix to IDENTIFY command in the server. Search the
3762 client first by hash not nickname. Affected file is
3765 * Fixed the silc_client_close_connection to support closing
3766 the client to client connections wihtout deleting too much
3767 data. Affected file lib/silcclient/client.c.
3769 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3770 are received if protocol used to be active but is not anymore
3771 the application would crash due to NULL pointer dereference.
3772 Affected files silcd/server.c and lib/silcclient/client.c.
3774 * Added `hash' field to the SilcClientConnection to include
3775 the hash function negotiated in the SKE protocol.
3777 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3778 to set the channel founder authentication data. A client can
3779 claim the founder rights later by providing the authentication
3780 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3781 This way the channel founder can regain the channel founder
3782 privileges even it is left the channel. This works only on
3783 local server and the client must be connected to the same
3784 server to be able to regain the founder rights. Updated the
3785 protocol specs accordingly.
3787 Added support to the CMODE command in the client to set the
3788 founder auth data. Read the README to see how to set it.
3790 Added support to the CUMODE command to claim the founder
3791 rights. Read the README to see how to do it.
3793 Added support for the founder authentication to the Channel
3794 Entry in the server. Affected file silcd/idlist.h.
3796 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3797 server's CMODE command. Affected file silcd/command.c.
3799 * Added the following new functions into lib/silccore/silcauth.[ch]:
3800 silc_auth_get_method and silc_auth_get_data.
3802 * The server now saves the remote hosts public key to the
3803 SilcIDListData pointer. Affected file silcd/protocol.c.
3805 * The normal server now does not remove the channel entry from
3806 the cache if the founder authentication data is set. It used
3807 to remove it if the founder was the last one on the channel on
3808 the server and left the channel. The auth data is saved and
3809 if the channel is re-joined later the old entry is used with
3810 the old auth data. Affected files silcd/command_reply.c and
3813 * Removed the `pkcs' field from the SilcIDListData structure
3814 in the server; it is not used. Affected file silcd/idlist.h.
3816 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3818 * Fixed packet processing on slow links. Partial packets were
3819 never re-processed because the incoming data buffer was cleared
3820 by the application. Application must not directly clear the
3821 sock->inbuf, the packet processing routines handle it. Fixed
3822 this in client library and in server.
3824 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Fixed the WHOIS and IDENTIFY send reply function to really
3827 check whether to send list or just one entry. Affected file
3830 * Cleaned up the LEAVE command's channel key distribution. The
3831 affected file silcd/command.c.
3833 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3834 can enforce the channel mode as well. In that case the ID
3835 includes the ID of the server. The code now enforces the
3836 mode change if the router have different mode than the server.
3838 * The notify client operation with CMODE_CHANGE notify can now
3839 return NULL client_entry pointer if the CMODE was not changed
3840 by client. Application must check for this.
3842 * Added <Server ID> argument to INFO command to support server
3843 info fetching by Server ID.
3845 * Added silc_server_announce_get_channel_users to get assembled
3846 packets of channel users of the specified channel. Affected
3847 file silcd/server.[ch].
3849 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3850 was freed underneath the ID Cache.
3852 * Re-announce clients when the server received CHANNEL_CHANGE
3853 notify from the router. Affected file silcd/packet_send.c.
3855 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3858 crashed since it did not handle the fact that there is no cipher
3859 called "3" and didn't check the error condition. Now fixed.
3861 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3862 flag. It can be used to send message requests.
3864 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3866 * Implemented the RESTART command in the client.
3868 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3869 notice type messages. Added notice printing to the user
3872 * The channel keys are not re-generated if the channel's mode
3873 is PRIVKEY, ie private key on the channel exists. Affected
3874 files silcd/server.c and silcd/command.c.
3876 * Fixed a little bug in channel message delivery when channel
3877 private keys are set in the server. Affected file is
3878 silcd/packet_send.c.
3880 * Changed the setting on channel->on_channel = TRUE from the
3881 silc_client_save_channel_key to the JOIN command reply. The
3882 key payload is not received if the private channel key is set.
3883 Affected file lib/silcclient/command_reply.c and the
3884 lib/silcclient/client_channel.c.
3886 * When the CMODE_CHANGE notify is sent and the channel private
3887 key mode is removed the channel key must be re-generated in
3888 other cells as well. Added this support for the router in the
3889 silcd/packet_receive.c.
3891 * Added new local command NOTICE to send notice message on
3892 channel. Affected file silc/local_command.[ch].
3894 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3896 * Added new local command ME to the client. It is used to send
3897 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3898 some action. Affected file silc/local_command.[ch].
3900 * Changed channel_message and private_message client operations
3901 to deliver the message flags to the application. Added also
3902 the `flags' arguments to the silc_client_send_channel_message
3903 and silc_client_send_private_message functions. Affected file
3906 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Redefined the Private Message Payload to support private message
3909 keys and to support the new private message flags. Updated
3910 the protocol specs. Flags makes it possible to have for example
3911 CTCP style messages.
3913 * Added new type SilcPrivateMessagePayload and defined an API
3914 for it in the lib/silcclient/silcprivate.[ch].
3916 * Tested private message private keys successfully. Tested the
3917 private message key set, unset and list commands with the new
3920 * Redefined the Channel Message Payload to include the channel
3921 message flags (equal with private message flags) to support
3922 for example CTCP style messages.
3924 * Defined some of the message (for channel and private message)
3925 flags. Updated the protocol specs and added the flags to the
3926 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3928 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Added SilcKeyAgreementStatus type to the key agreement routines
3931 to indicate the current status and error if one occured.
3932 The status types are defined in the lib/silcclient/silcapi.h.
3934 * Added new local command KEY that is used to set and unset private
3935 keys for channels, set and unset private keys for private messages
3936 with remote clients and to send key agreement requests and
3937 negotiate the key agreement protocol with remote client. The
3938 key agreement is supported only to negotiate private message keys,
3939 it currently cannot be used to negotiate private keys for channels,
3940 as it is not convenient for that purpose.
3942 * Fixed a minor pending callback setting bug in the function
3943 silc_client_get_client_by_id_resolve, now the function works.
3944 Affected file lib/silcclient/idlist.c.
3946 * Added function silc_net_get_local_port to get local bound
3947 port by socket. Added to lib/silcutil/silcnet.[ch].
3949 * Added `sockets' and `sockets_count' fields to the SilcClient
3950 object. They hold the sockets of the listenning sockets in
3951 the client. Listenning sockets may be for example the key
3952 agreement server. Affected file lib/silcclient/client.[ch].
3953 Added functions the silc_client_add_socket and the
3954 silc_client_del_socket. They are exported to the application
3957 * Added ~./silc/clientkeys to support other client's public keys.
3959 * Renamed verify_server_key client operation to verify_public_key
3960 and added one argument to indicate the type of the connection
3961 (server, client etc.).
3963 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Added silc_server_connection_auth_request to handle the
3966 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3967 silcd/packet_receive.[ch].
3969 * Added silc_server_send_connection_auth_request into the
3970 silcd/packet_send.c to send the connection auth request packet.
3972 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3975 * Fixed the public key authentication in responder side in the
3976 server. The `auth_data' pointer includes the SilcPublicKey
3977 not the path to the public key. Affected file silcd/protocol.c.
3979 * Implemented the public key authentication in the initiator side
3980 in the server. Affected file silcd/protocol.c.
3982 * Removed the [RedirectClient] config section from the server
3983 configuration. Is not needed and I don't want to implement it.
3985 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Cleaned up the CMODE command in the server. It now works
3988 correctly and supports all the modes defined in the protocol.
3989 Affected file is silcd/command.c.
3991 * Added `hmac_name' field to the SilcChannelEntry in the server
3992 to hold the default HMAC of the channel. It can be set when
3993 creating the channel (with JOIN command). Affected files
3996 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3997 type to indicate the change of the current cipher and hmac
3998 on the channel. Client can safely ignore the <cipher> argument
3999 (if it chooses to do so) since the CHANNEL_KEY packet will
4000 force the channel key change anyway. The <hmac> argument is
4001 important since the client is responsible of setting the new
4002 HMAC and the hmac key into use.
4004 * Fixed the CMODE command in the client library as well.
4006 * Tested CMODE command in router environment successfully.
4008 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4010 * Show the version of the remote client (or server) when connecting
4011 to the server. It is logged to the log file. Affected file
4012 is silcd/protocol.c.
4014 * Fixed the KILLED notify handling in the client library. The
4015 client must be removed from all channels when receiving the
4018 Also, do not remove the client entry when giving the KILL
4019 command but when the KILLED notify is received.
4021 * Removed silc_idlist_find_client_by_nickname from the server.
4022 Not needed anymore. Affected files silcd/idlist.[ch].
4024 * Implemented the CHANNEL_CHANGE notify type handling to the
4025 server. Affected file silcd/server.c.
4029 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * Added silc_server_send_notify_invite to send the INVITE
4032 notify between routers.
4034 * Implemented the INVITE command correctly to the server.
4036 * Implemented the INVITE notify type handling in the server.
4038 * Implemented the INVITE command to the client library and on the
4041 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Added function silc_server_get_client_resolve to find the
4044 client entry by ID from all ID lists and then resolve it
4045 (using WHOIS) if it cannot be found. Affected file is
4048 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Implemented the BAN command to the client library.
4052 * The JOIN command in the server now checks the invite list
4055 * Changed the silc_command_reply_payload_encode_va and the
4056 silc_command_payload_encode_va to support that if argument is
4057 NULL it ignores and checks the next argument. Affected file
4058 lib/silccore/silccommand.c.
4060 * Added silc_server_send_notify_ban to send the BAN notify
4061 type between routers.
4063 * Chaned the silc_notify_payload_encode to support that if
4064 argument is NULL it ignores and checks the next argument.
4065 Affected file lib/silccore/silcnotify.c.
4067 * Tested ban lists in router environment successfully.
4069 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Implemented BAN command to the server, in silcd/command.[ch].
4073 * Removed the BAN and INVITE_LIST modes from the CMODE command
4076 * Added function silc_string_match to regex match two strings.
4077 Affected files lib/silcutil/silcutil.[ch].
4079 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4081 * Redefined parts of the SilcChannelEntry in the server to support
4082 the new ban and invite lists.
4084 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Redefined the INVITE command. The same command can be used to
4087 invite individuals to the channel but also to manage the invite
4088 list of the channel (to add to and remove from the invite list).
4089 Updated the protocol specs.
4091 * Added new command SILC_COMMAND_BAN that can be used to manage
4092 the ban list of the channel. Updated the protocol specs.
4094 * Removed the channel modes: the SILC_CMODE_BAN and the
4095 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4096 in the CMODE command. The equivalent features are now available
4097 using INVITE and BAN commands. Updated the protocol specs.
4099 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4100 in the network about change in the current ban list. The notify
4101 type is not used by the client.
4103 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4104 support the invite lists.
4106 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4108 * Added new function silc_string_regexify that converts string
4109 including wildcard characters into regex string that can
4110 be used by the GNU regex library. Added into the file
4111 lib/silcutil/silcutil.[ch].
4113 Added silc_string_regex_combine to combine to regex strings
4114 into one so that they can be used as one regex string by
4115 the GNU regex library. Added into the file
4116 lib/silcutil/silcutil.[ch].
4118 Added silc_string_regex_match to match two strings. It returns
4119 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4121 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * Imported GNU regex to the soruce tree into lib/contrib.
4124 Fixed some compiler warning from the regex.c.
4126 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Fixed MOTD command in the server to work in router environment.
4130 * Fixed the MOTD command in the client library to support
4131 the server argument in the command.
4133 * Added `nickname_len' argument to the silc_idlist_add_client
4134 in the server, as the `nickname' argument may be binary data
4137 * Added silc_idlist_get_channels to return all channels from
4140 * Implemented LIST command to the server. Affected file is
4143 * Implemented the LIST command to the client library and on the
4146 * Added [<user count>] argument to the LIST command reply.
4147 With private channels the user count is not shown.
4149 * Updated TODO and README.
4151 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * The client entry's data.registered must be TRUE even with
4154 global client entry on global client list. The data.registered
4155 is used to check whether the client is anymore in the network,
4156 for example with WHOWAS command so it must be valid.
4158 * Fixed the WHOWAS command in the server. It now actually works
4159 in router environment. Added function into silcd/command_reply.c
4160 silc_server_command_reply_whowas_save.
4162 * Added silc_idlist_purge function to the silcd/idlist.c
4163 to periodically purge the ID Cache.
4165 * Fixed INFO command in the server. It works now in router
4166 environment. Added <server name> argument to the INFO command
4167 reply. Updated the protocol specs.
4169 * Fixed minor bug in silc_idcache_purge to not purge if the
4170 expire value is zero.
4172 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4173 they were buggy because of the WHOWAS information.
4175 * Fixed local command MSG to handle the async resolving of
4176 the remote client properly. It used to fail the first MSG.
4177 Affected file silc/local_command.c.
4179 * Added `data_len' field to SilcIDCache context.
4181 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Update TODO. Todo in commands in the server.
4185 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4188 used by routers as broadcast packet to inform other routers
4189 about the changed user mode.
4191 Implemented the notify handling in the server. Affected file is
4192 silcd/packet_receive.c. Added the function
4193 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4195 * Added new generic Channel Payload and deprecated the New Channel
4196 Payload. The New Channel Payload is now the generic Channel
4199 * Added new argument `mode' to the silc_server_send_new_channel
4200 as it is required in the Channel Payload now.
4202 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4203 and created a new and real SilChannelPayload to represent the
4204 new generic Channel Payload. Implemented the encode/decode
4205 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4207 * Added silc_server_get_client_channel_list to return the list
4208 of channels the client has joined for WHOIS command reply.
4209 Affected file silcd/server.[ch].
4211 * Implemented the channel list sending in the WHOIS command reply
4212 in server and in the client.
4214 Implemented the channel list displaying on the user interface
4215 as well. Affected file silc/client_ops.c.
4217 * Added silc_channel_payload_parse_list to parse list of Channel
4218 Payloads. It returns SilcDList list of SilcChannelPayloads.
4219 Client for example can use this function to parse the list of
4220 channels it receives in the WHOIS command reply. The caller
4221 must free the list by calling silc_channel_payload_list_free.
4222 Affected files lib/silccore/silcchannel.[ch].
4224 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Added one new argument <user mode> to the WHOIS command reply
4227 to return the mode of the user in SILC. Updated the protocol
4230 Implemented it to the server and client.
4232 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Fixed the mode printing on the user interface on joining.
4235 Affected file silc/client_ops.c.
4237 * Implemented the UMODE command and user modes in general to the
4238 client library and to the user interface.
4240 * Implemented the UMODE command to the server.
4242 * The server now sends UNKNOWN_COMMAND error status if client sends
4243 unknown command. Affected file silcd/command.c.
4245 * All server commands now handle the command identifier the right
4246 way when sending the command reply to the client. The client can
4247 use to identify the command replies with the identifier.
4249 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Added silc_server_get_client_route to resolve the route to
4252 the client indicated by the client ID. Affected file is
4255 * Added silc_server_relay_packet as general function to relay
4256 packet to arbitrary destination. This deprecates functions
4257 like _send_private_message_key, _relay_notify etc. Affected
4258 file is silcd/packet_send.[ch].
4260 Removed silc_server_send_key_agreement,
4261 silc_server_send_private_message_key and
4262 silc_server_packet_relay_notify functions from the file
4263 silcd/packet_send.[ch].
4267 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4268 server. Affected file silcd/packet_receive.[ch].
4270 * Implemented the KILL command to the client. Implemented the
4271 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4272 Affected files lib/silcclient/command[_reply].c and
4273 lib/silcclient/client_notify.c. Implemented the KILL notify
4274 printing in the user inteface.
4276 * Fixed a lot silc_parse_nick memory leaks from the client
4277 library in the file lib/silcclient/command.c.
4279 * Changed the silc_server_send_notify_on_channels's `sender'
4280 argument from SilcSocketConnection to SilcClientEntry to
4281 check the sender as entry and not as connection object and not
4282 to send to the client provided as argument. The affected file
4283 is silcd/packet_send.[ch].
4285 * The notify packets that are destined directly to the client used
4286 to not to be processed by the server. Now changed that and the
4287 server processes all notify packets. After relaying the packet
4288 to the client the notify packet is processed in the server.
4290 * The silc_server_free_client_data now checks whether there is
4291 pending outgoing traffic for the client and purges the data to
4292 the network before removing the client entry.
4294 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4297 an client is killed from the SILC Network. Updated the protocol
4300 Added new function silc_server_send_notify_killed to the
4301 silcd/packet_send.[ch].
4303 * Added function silc_server_packet_relay_notify to relay notify
4304 packets that are destined directly to a client. In this case
4305 the server does not process the notify packets but merely relays
4306 it to the client. Affected file silcd/packet_send.[ch].
4308 Added also silc_server_packet_process_relay_notify to check
4309 whereto relay the notify. Affected file is
4310 silcd/packet_receive.[ch].
4312 * Implemented the KILL command to the server.
4316 * Added the backup schema desgined last fall to the protocol
4317 specs for everyone to see. The specification is in the
4318 *-spec-xx.txt draft and the packet type definitions for the
4319 backup routers is in *-pp-xx.txt draft. Thusly, added also
4320 new packet type SILC_PACKET_CELL_ROUTERS.
4322 * A big security problem in the implementation discovered. The
4323 signoff of an client did not cause new channel key generation
4324 which it of course should've done. The channel keys must be
4325 always re-generated when client leaves (or signoffs) the channel.
4326 The silc_server_remove_from_channels funtion now handles
4327 the channel key re-generation.
4329 * Added `sender' argument to the silc_server_send_notify_on_channels
4330 to not to send the client provided as argument. Affected file
4331 silcd/packet_send.[ch].
4333 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Implemented OPER and SILCOPER commands into the server and
4338 * Added silc_auth_verify and silc_auth_verify_data to verify
4339 the authentication directly from the authentication payload.
4340 It supports verifying both passphrase and public key based
4341 authentication. Affected file lib/silccore/silcauth.[ch].
4343 * Added `hash' field to the SilcIDListData structure. It is the
4344 hash negotiated in the SKE protocol. Affected file is
4347 * Slight redesigning of the SilcAuthPayload handling routines.
4348 Do not send SilcPKCS but SilcPublicKey as argument.
4350 * Implemented the public key authentication support to the
4351 serverconfig. The public key is loaded from the provided path
4352 and saved as authentication data to void * pointer. Thus,
4353 changed the unsigned char *auth_data to void *auth_data;
4355 * Fixed SHUTDOWN command to send the reply before the server
4356 is shutdown. :) Affected file silcd/command.c.
4358 * Fixed fatal bug in CONNECT command. The hostname was invalid
4359 memory and server crashed. Affected file silcd/command.c.
4361 * Fixed fatal bug in CLOSE command. The server_entry became
4362 invalid but was referenced later in the command. Affected file
4365 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Fixed fatal bug in failure packet handling. Server ignored
4368 the failure and thus crashed when it came.
4372 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4375 that the command may be executed only once in (about) 2 seconds.
4376 The old SILC_CF_LAG flag is same but allows command bursts up
4377 to five before limiting.
4379 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4380 server code. Various commands now includes the CF_LAG_STRICT
4381 flag to disallow any kind of miss-use of the command.
4383 * Fixed the silc_buffer_unformat to not to allocate any data
4384 if the length of the data is zero. It used to allocate the
4385 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4387 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Changed the format of AdminConnection configuration section
4390 in the server. Added username of the admin to the format.
4391 Affected files silcd/serverconfig.[ch].
4393 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4394 to return admin configuration data by host, username and/or
4397 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Implemented WHOWAS command to the server. Added the functions:
4401 silc_server_command_whowas_parse,
4402 silc_server_command_whowas_send_reply,
4403 silc_server_command_whowas_from_client and
4404 silc_server_command_whowas_from_server
4406 * Added <Client ID> argument to the WHOWAS command reply. Updated
4407 the protocol specs accordingly.
4409 * Implemented WHOWAS command and command_reply to the client
4412 Implemented the WHOWAS printing on the user interface.
4414 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Added new argument to the WHOWAS command reply, the real name.
4417 It is an optional argument. Updated the protocol specs.
4419 * Added SilcIDCacheDestructor callback that is registered when
4420 the SilcIDCache is allocated. The callback is called when
4421 an cache entry in the ID Cache expires, or is purged from the
4422 cache. Added into lib/silccore/idcache.[ch].
4424 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4425 to destruct the client entries when the cache entry expires.
4426 Other ID Cache's in server and in the client library ignores
4429 * If the ID Cache entry's `expire' field is zero then the entry
4430 never expires. Added boolean `expire' argument to the
4431 silc_idcache_add function in the lib/silccore/idcache.[ch].
4432 If it is TRUE the default expiry value is used.
4434 * Added silc_server_free_client_data_timeout that is registered
4435 when client disconnects. By default for 5 minutes we preserve
4436 the client entry for history - for WHOWAS command.
4438 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Added support to the server to enforce that commands are not
4441 executed more than once in 2 seconds. If server receives
4442 commands from client more frequently, timeout is registered
4443 to process the commands. Affected file silcd/command.c.
4444 Added new function silc_server_command_process_timeout.
4446 * Changed NICK_NOTIFY handling in client library to check that
4447 if the client's nickname was changed, so there is no need to
4448 resolve anything from the server.
4450 * Removed error printing from the WHOIS and IDENTIFY commands.
4451 If error occurs then it is ignored silently in the client library.
4452 The application, however, may map the received error to
4453 human readable error string. The application currently maps
4454 the NO_SUCH_NICKNAME error to string.
4456 * Made the command status message public to the application. Moved
4457 them from lib/silcclient/command_reply.c to
4458 lib/silcclient/command_reply.h. The application can map the
4459 received command status to the string with the
4460 silc_client_command_status_message function.
4462 * Added check to the server to check that client's ID is same
4463 as the Source ID in the packet the client sent. They must
4466 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Added dist-bzip hook to the Makefile.am to make bzip2
4469 compressed distributions.
4471 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Server now enforces the maximum length for the nickname and
4474 the channel as protocol specification dictates. 128 bytes for
4475 nickname and 256 bytes for channel name.
4477 * Moved the WHOIS printing to the application. The client libary
4478 does not print out the WHOIS information anymore, the application
4479 must do it. Renamed silc_client_command_reply_whois_print to
4480 the silc_client_command_reply_whois_save.
4482 The client's idle time is also sent to the application now, and
4483 the idle is shown on screen.
4485 * Added silc_client_command_reply_identify_save to save the
4486 received IDENTIFY entries.
4488 * Do not check for channel private keys in message sending and
4489 reception if the channel does not have the PRIVKEY mode set.
4490 Affected file lib/silclient/client_channel.c.
4492 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4495 just surfaced after chaning the JOIN procedure.
4497 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Added silc_client_get_clients_by_list to get client entries
4500 from Client ID list, that is returned for example by JOIN
4501 and USERS command replies. The application should use this
4502 function for example when JOIN command reply is received to
4503 resolve the clients already on the channel (library does not
4504 do that anymore as USERS command reply is not used in the JOIN
4505 procedure anymore). Affected files lib/silcclient/silcapi.h and
4506 lib/silcclient/idlist.c.
4508 * JOIN command reply and USERS command reply returns now SilcBuffer
4509 pointers instead of unsigned char pointers when returning
4510 the client list and mode list.
4512 * Added <Client ID> argument to the JOIN command reply, mainly
4513 for the server to identify for which client the command was
4514 originally sent. Updated protocol specs accordingly.
4516 * Added SilcDlist private_key pointer to the SilcChannelEntry
4517 in the client to support the channel private keys. Affected
4518 file is lib/silcclient/idlist.h.
4520 * Added SilcChannelPrivateKey argument to the function
4521 silc_client_send_channel_message so that application can choose
4522 to use specific private ke if it wants to. If it is not provided,
4523 the normal channel key is used, unless private keys are set.
4524 In this case the first (key that was added first) is used
4525 as the encryption key.
4527 * Implemented the support for channel private key handling.
4528 Implemented the following functions:
4530 silc_client_add_channel_private_key,
4531 silc_client_del_channel_private_keys,
4532 silc_client_del_channel_private_key,
4533 silc_client_list_channel_private_keys and
4534 silc_client_free_channel_private_keys
4536 Affected file lib/silcclient/client_channel.c.
4538 * Added the support for the private keys in the channel message
4539 sending and encryption and in the message reception and
4540 decryption. Affected funtions are
4541 silc_client_send_channel_message and silc_client_channel_message.
4543 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Added SKE's key verify callback to the client library's
4546 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4548 * Removed the statement that server (or router) must send USERS
4549 command reply when joining to the channel so that the client
4550 knows who are on the channel. Instead, the client list and
4551 client's mode list is now sent in the JOIN command reply to the
4552 client who joined channel. This is better solution.
4554 * Added function silc_server_get_users_on_channel and function
4555 silc_server_save_users_on_channel to the silcd/server.[ch].
4557 * Removed function silc_server_command_send_users from the
4560 * Do not show topic on the client library anymore. The topic is
4561 sent in the command reply notify to the application and the
4562 application must show the topic now.
4564 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Added client searching by nickname hash into the IDENTIFY and
4567 WHOIS commands in the server as they were clearly missing from
4568 them. Affected file is silcd/command.c.
4570 * Fixed a bug in private message receiving in the client library.
4571 The remote ID was freed and it wasn't supposed, now it is
4574 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4576 * Minor fix to the channel payload; allocate the data area, as it
4577 needs to be of specific length.
4579 * If the key agreement port is zero then the operating
4580 system will define the bound port. Affected files are
4581 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4583 * Added new function silc_channel_payload_decrypt into the file
4584 lib/silccore/silcchannel.[ch].
4586 * Moved the channel message etc, check from silc_packet_decrypt
4587 to applications. The library calls now a generic
4588 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4589 when the packet is either normal or special. This was done to
4590 allow more wide range of checking that was not allowed when
4591 the code was in library. Now applications can do virtually any
4592 checks to the packet and return to the library the decision how
4593 the packet should be processed. Affected files are
4594 lib/silccore/silcpacket.[ch].
4596 Added silc_server_packet_decrypt_check to the server and
4597 silc_client_packet_decrypt_check to the client library.
4599 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4600 to send with specified source and destination information.
4602 * Channel message delivery between routers was broken after the
4603 channel key distribution was fixed earlier. The channel key
4604 was used be to distributed to other routers as well which is not
4605 allowed by the protocol. Now this is fixed and channel keys
4606 really are cell specific and the channel message delivery between
4607 routers comply with the protocol specification.
4609 * Fixed various commands in server to check also the global list
4610 for the channel entry and not just the local list. The affected
4611 file silcd/command.c.
4613 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4615 * Added assert()s to buffer formatting and unformatting routines
4616 to assert (if --enable-debug) when error occurs. Affected
4617 file: lib/silcutil/silcbuffmt.c.
4619 * Changed to auto-reconnect to check whether the remote host is
4620 router and register the re-connect timeout if it is. It used
4621 to check that whether we are normal server, but router must do
4622 auto-reconnect with another router as well. Affected file
4625 * Removed the [<key len>] option from CMODE command as the cipher
4626 name decides the key length, nowadays. See the defined ciphers
4627 from the protocol specification.
4629 * Added [<hmac>] option to the CMODE command to define the HMAC
4630 for the channel. Added SILC_CMODE_HMAC channel mode.
4632 * Added [<hmac>] option for the JOIN command so that user can
4633 select which HMAC is used to compute the MACs of the channel
4636 * Added Hmac field to the Channel Message Payload. The integrity
4637 of plaintext channel messages are now protected by computing
4638 MAC of the message and attaching the MAC to the payload. The
4639 MAC is encrypted. Now, it is clear that this causes some
4640 overhead to the size of the packet but rationale for this is that
4641 now the receiver can verify whether the channel message decrypted
4642 correctly and also when private keys are set for the channel the
4643 receiver can decrypt the packet with several keys and check from
4644 the MAC which key decrypted the message correctly.
4646 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4647 lib/silccrypt/silccipher.[ch].
4649 * Added silc_hash_len to return the digest length into the
4650 lib/silcrypt/silchash.[ch].
4652 * Rewrote parts of Silc Channel Payload interface in the
4653 lib/silccore/silcchannel.[ch]. The encode function now also
4654 encrypts the packet and parse function decrypts it.
4656 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Fixed a minor formatting bug in the SKE's key material processing.
4659 It actually might have processed the keys wrong way resulting
4662 * Redefined the mandatory HMAC algorithms and added new algorithms.
4663 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4664 and hmac-md5 truncated to 96 bits. The mandatory is now
4665 hmac-sha1-96. Rest are optional (including the one that used
4666 to be mandatory). Rationale for this is that the truncated HMAC
4667 length is sufficient from security point of view and can actually
4668 make the attack against the HMAC harder. Also, the truncated
4669 HMAC causes less overhead to the packets. See the RFC2104 for
4672 * Added new [hmac] configuration section. The SKE used to use
4673 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4674 is of course wrong. The official names that must be proposed in
4675 the SKE are the ones defined in the protocol specification
4676 (hmac-sha1-96 for example). The user can configure any hmac
4677 using any hash function configured in the [hash] section. At
4678 least, the mandatory must be configured.
4680 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4682 * Added HMAC list to the SKE proposal list. It has now both
4683 hash algorithm list and HMAC list. This makes the protocol
4684 incompatible with previous versions. The SKE now seems to work
4685 the way it is supposed to work, for the first time actually.
4687 * Defined plain Hash algorithms to the protocol specification.
4690 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4692 * Implemented support for key agreement packets into the server.
4693 Added functions silc_server_key_agreement and
4694 silc_server_send_key_agreement. Other than these functions,
4695 server has nothing to do with this packet.
4697 * Added support for private message key packets into the server.
4698 Added functions silc_server_private_message_key and
4699 silc_server_send_private_message_key.
4703 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4704 called in the protocol's final callback instead in the END
4705 protocol state. This makes a little more sense and in the same
4706 time in client we can use the same protocol routines for normal
4707 key exchange and to key agreement packet handling as well.
4709 * Added to both client's and server's KE protocol context the
4710 SilcSKEKeyMaterial pointer to save the key material. We will
4711 bring the key material to the protocol's final callback by doing
4712 this. The final callback must free the key material.
4714 * Added SKE's packet_send callback into client's KE protocol
4715 context so that the caller can choose what packet sending function
4716 is used. This way we can use different packet sending when
4717 doing normal SKE when doing key agreement packet handling (in
4718 the key agreement packet handling we do not want to encrypt
4721 * Implemented the responder side of the key agreement routines
4722 in the client. The client can now bind to specified port and
4723 accept incoming key negotiation. The key material is passed
4724 to the application after the protocol is over.
4726 * Implemented the processing of incoming Key Agreement packet
4727 in the client. Added function silc_client_key_agreement to
4730 * Implemented the intiator side of the key agreement routines
4731 in the client. The client can now initiate key agreement with
4732 another remote client. The key material is passed to the
4733 application after the protocol is over.
4735 * Created client_keyagr.c to include all the key agreement
4738 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4739 SILC_TASK_CALLBACK except that it is not static.
4741 * Created client_notify.c and moved the Notify packet handling
4742 from the client.[ch] into that file.
4744 * Created client_prvmsg.c and moved all private message and
4745 private message key routines from the client.[ch] into that file.
4747 * Create client_channel.c and moved all channel message and
4748 channel private key routines from the client.[ch] into that file.
4750 * Changed silc_client_get_client_by_id_resolve to resolve with
4751 WHOIS command instead of IDENTIFY command, in the file
4752 lib/silclient/idlist.c.
4754 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Implemented the SKE's responder side to the Client library.
4758 * When FAILURE is received to the protocol do not trust it
4759 blindly. Register a timeout to wait whether the remote closes
4760 the connection as it should do it, only after that process the
4761 actual failure. This was changed to both client and server.
4763 * Added client_internal.h to include some of the structures
4764 there instead of client.h in lib/silcclient/.
4766 * Added function silc_task_unregister_by_callback to unregister
4767 timeouts by the callback function.
4769 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4771 * Some "Incomplete WHOIS info" errors has been appearing on the
4772 log files. Took away the entry->userinfo check from WHOIS
4773 reply sending. The entry->userinfo is now " " if client did not
4774 provide one. I thought this was fixed earlier but something
4775 is wrong still. Let's see if the error still appears.
4777 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Fixed a minor bug in the login when the channel key is
4780 re-generated in the server. It used to generate the key in
4781 wrong order and thus caused problems in the channel traffic.
4783 * Fixed a minor bug in channel key distsribution after
4784 KICK command. The key was not sent to the router even though
4787 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Added silc_ske_process_key_material_data as generic routine
4790 to process any key material as the SILC protocol dictates. The
4791 function is used by the actual SKE library but can be used by
4792 applications as well. This relates to the private message keys
4793 and the channel private keys since they must be processed the
4794 same way the normal SILC session keys. The protocol dictates
4795 this. Affected files: lib/silcske/silcske.[ch].
4797 Added also silc_ske_free_key_material to free the
4798 SilcSKEKeyMaterial structure.
4800 * Defined silc_cipher_set_key function to set the key for
4801 cipher without using the object's method function. The affected
4802 files: lib/silccrypt/silccipher.[ch].
4804 * Implemented silc silc_client_add_private_message_key,
4805 silc_client_add_private_message_key_ske,
4806 silc_client_del_private_message_key,
4807 silc_client_list_private_message_keys and
4808 silc_client_free_private_message_keys functions in the
4811 Added functions silc_client_send_private_message_key to send
4812 the Private Message Key payload and silc_client_private_message_key
4813 to handle incoming Private Message Key payload.
4815 * Added Cipher field to the Private Message Key payload to set
4816 the cipher to be used. If ignored, the default cipher defined
4817 in the SILC protocol (aes-256-cbc) is used.
4819 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Removed lib/silcclient/ops.h file.
4823 Redefined parts of the SILC Client Library API. Created new
4824 file silcapi.h that deprecates the ops.h file and defines the
4825 published Client Library API. Defined also private message key
4826 API and channel private key API into the file.
4828 This is the file that the application must include from the
4829 SILC Client Library. Other files need not be included by
4830 the application anymore.
4832 * Added new key_agreement client operation callback and also
4833 defined the Key Agreement library API for the application.
4835 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4838 is used by clients to request key negotiation between another
4839 client in the SILC network. If the negotiation is started it
4840 is performed using the SKE protocol. The result of the
4841 negotiation, the secret key material, can be used for example
4842 as private message key.
4844 Implemented the Key Agreement payload into the files
4845 lib/silccore/silauth.[ch].
4847 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Redefined ciphers for the SILC protocol. Added some new ciphers
4850 and defined the key lengths for the algorithms. Changed the
4851 code accordingly. The default key length is now 256 bits.
4853 * Fixed SKE key distribution function silc_ske_process_key_material
4854 when the key length is more than 128 bits. The default key
4855 length in SILC is now 256 bits.
4857 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4858 to indicate unsupported algorithm.
4860 * Renamed rijndael.c to aes.c and all functions as well.
4862 * Fixed a long standing channel key setting bug in client library.
4863 Weird that it has never surfaced before.
4865 * Fixed bug in channel deletion. If the entire channel is removed
4866 then it must also delete the references of the channel entry
4867 from the client's channel list as the client's channel entry and
4868 the channel's client entry share same memory.
4870 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4872 * Implemented CONNECT and SHUTDOWN commands in the client.
4874 * Implemented CLOSE command to the client.
4876 * Added the function silc_idlist_find_server_by_name into the
4877 files silcd/idlist.[ch].
4879 Added the function silc_idlist_find_server_by_conn into the
4880 files silcd/idlist.[ch].
4882 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * DIE command was renamed to SHUTDOWN. Updated the both code
4887 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4888 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4890 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4893 * Added function silc_server_create_connection function to create
4894 connection to remote router. My server implementation actually
4895 does not allow router to connect to normal server (it expects
4896 that normal server always initiates the connection to the router)
4897 so the CONNECT command is only good for connecting to another
4900 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4903 or some other client was kicked from the channel.
4905 Implemented the handling of the notify type to both client
4908 Implemented silc_server_send_notify_kicked to send the KICKED
4909 notify. It is used to send it to the server's primary router.
4911 * Implemented the KICK command into server and client.
4913 * Added `query' argument to the silc_idlist_get_client function
4914 to indicate whether to query the client from server or not if
4917 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4918 to indicate that the client is not channel founder.
4922 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Removed the rng context from SilcPacketContext structure and
4925 changed that the packet routine uses the Global RNG API.
4927 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Added support for quit message that client can "leave" on the
4930 channel when it quits the SILC. It is ditributed inside the
4931 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4933 Added silc_server_free_client_data that will take the
4934 signoff message as argument.
4936 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4938 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Updated parts of the protocol specification to keep it up
4943 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4946 payloads in one packet.
4948 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4949 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4950 use now the new List flag.
4952 * Also deprecated the following packet types: REPLACE_ID,
4953 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4955 * Added list support for Notify packet in server.
4957 * Added silc_server_send_notify_channel_change to send the
4958 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4959 the silc_server_send_replace_id.
4961 * Added silc_server_send_notify_nick_change to send the
4962 NICK_CHANGE notify type. Deprecates the function
4963 silc_server_send_replace_id.
4965 * Added silc_server_send_notify_join to send the JOIN notify type.
4966 Deprecates the function silc_server_send_new_channel_user.
4968 * Added silc_server_send_notify_leave to send LEAVE notify type.
4969 Deprecates the function silc_server_send_remove_channel_user.
4971 * Added silc_server_send_notify_cmode and
4972 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4973 types. Deprecates the silc_server_send_set_mode function.
4975 * Added SERVER_SIGNOFF notify type to indicate that server has
4976 quit. This means that all clients on the channel from that
4977 server will drop. This can be also used when netsplit happens.
4979 Deprecated REMOVE_ID packet type since it is not needed anymore
4982 Added silc_server_send_notify_server_signoff to send the
4983 SERVER_SIGNOFF notify type. Deprecates the function
4984 silc_server_send_remove_id.
4986 Added also silc_server_send_notify_signoff to send the
4987 SIGNOFF notify type.
4989 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4990 SILC protocol from this day on. Changed the protocol
4991 specification as well.
4993 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4994 notify type. It is used between routers to notify about
4995 topic changes on a channel.
4997 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5000 * Partly updated the protocol specification to comply with the
5001 changes now made. It is still though a bit outdated.
5003 * The JOIN notify type now takes one extra argument <Channel ID>.
5004 The packet used to be destined to the channel but now the
5005 JOIN type may be sent as list thus it is impossible to
5006 destine it to any specific channel. By adding this argument
5007 it is again possible.
5009 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Added CREDITS file. The CHANGES and CREDITS file will appear
5012 in the distribution as well.
5014 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5017 types in the server's silcd/packet_receive.c.
5019 * Implemented CMODE and CUMODE to work in router environment.
5021 * Fixed minor encoding and decoding buglet from the
5022 lib/silccore/silcmode.c.
5024 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5027 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5029 * Changed all SilcConfigServer* and silc_config_server* to
5030 SilcServerConfig* and silc_server_config*, respectively.
5033 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5035 * Associated the ID (client or server ID) to the Authentication
5036 Payload to avoid any possibility of forging. Updated the
5037 protocol specification and the code accordingly.
5039 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * The RSA key length is now save to the RsaKey context in the
5042 key generation process in lib/silccrypt/rsa.c. The key length
5043 is now used to figure out the maximum size of the block allowed
5044 to be encrypted/signed.
5046 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5047 is equivalent to the silc_mp_mp2bin but does not allocate any
5050 * Changed silc_mp_mp2bin API to take length argument. If it is
5051 non-zero then the buffer is allocated that large. If zero, then
5052 the size is approximated using silc_mp_sizeinbase, which however
5055 * Created Global RNG API which is global RNG that application can
5056 initialize. After initializing, any routine anywhere in the
5057 code (including library) can use RNG without allocating a new
5058 RNG object. This was done to allow this sort of use of the
5059 RNG in code that has no chance to allocate RNG object. All
5060 applications currently allocate this and many routines in the
5061 library use this. Affected file lib/silccrypt/silcrng.[ch].
5063 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5064 it to use the Global RNG API.
5066 * Defined Authentication Payload into protocol specification that
5067 is used during SILC session to authenticate entities. It is
5068 used for example by client to authenticate itself to the server
5069 to obtain server operator privileges.
5071 Implemented this payload into the lib/silccore/silcauth.[ch].
5072 Implemented also routines for public key based authentication
5073 as the new protocol specification dictates.
5075 Moved definitions of different authentication methods from
5076 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5078 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5079 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5080 silc_pkcs_verify_with_hash functions into the file
5081 lib/silccrypt/silcpkcs.[ch].
5083 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * The client entry's userinfo pointer must be always valid.
5086 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5087 will fail since it requires the userinfo. Now, the userinfo
5088 is allocated as "" if actual userinfo does not exist. Actually,
5089 it must exist and it is totally Ok to drop client connections
5090 that does not announce the userinfo. However, we will make
5091 this workaround for now.
5093 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5094 to return the remote port by socket.
5096 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5099 SILC_SERVER_PENDING_EXEC and added an new macro
5100 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5101 data or when error occurs while processing the pending command.
5103 Added new argument `destructor' into silc_server_command_pending
5104 and to the SilcServerCommandPending object. This destructor is
5105 now called after calling the pending callback or if error occurs
5106 immediately. If error occurs the actual pending callback won't
5107 be called at all - only the destructor. The destructor may be
5108 NULL if destructor is not needed.
5110 All this applies for client library code as well. Similar
5111 changes were made there as well for the pending commands.
5113 In the client, the application must now allocate the
5114 SilcClientCommandContext with the silc_client_command_alloc
5117 * Added reference counter to the SilcServerCommandContext. Added
5118 function silc_server_command_alloc and silc_server_command_dup
5121 Same type of functions added to the client library for the same
5124 * Removed the cmd_ident from IDListData away since it is now
5125 global for all connections. It is the command identifier used
5126 in command sending and with pending commands. The affected file
5129 * Added reference counter to the SilcSocketConnection objecet to
5130 indicate the usage count of the object. The object won't be
5131 freed untill the reference counter hits zero. Currently only
5132 server uses this, and client ignores it. The client must be
5133 set to use this too later. The affected files are
5134 lib/silccore/silcsockconn.[ch]. Added also the function
5135 silc_socket_dup to increase the reference counter.
5137 This was mainly added because it is possible that the socket
5138 is removed underneath of pending command or other async
5139 operation. Now it won't be free'd and proper DISCONNECTING
5140 flags, etc. can be set to avoid sending data to connection that
5141 is not valid anymore.
5143 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5144 the connection. After that it sets SILC_SET_DISCONNECTED.
5145 It is, however, possible that the socket data is not still freed.
5146 The silc_server_packet_process now checks that data is not
5147 read or written to connection that is DISCONNECTED. The socket
5148 get's freed when the reference counter hits zero.
5150 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Changed the client operation API: channel_message operation's
5153 `sender' is now the client entry of the sender, not the nickname
5154 and the `channel' is the channel entry, not the channel name.
5156 In the private_message operation the `sender' is now also the
5157 client entry of the sender not the nickname.
5159 Affected file is lib/silcclient/ops.h and all applications
5160 using the client operations.
5162 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Moved the calling of ops->connect() from connect_to_server_final
5165 into receive_new_id functin since that is the point when the
5166 client is actually allowed to send traffic to network. The
5167 affected file is lib/silcclient/client.c.
5169 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5172 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5173 (if needs broadcasting) instead of broadcasting the packets one
5174 by one which would make a burst in the network traffic.
5176 * Added `broadcast' argument to the functions in silcd/server.[ch]
5177 silc_server_create_new_channel[_with_id] to indicate whether
5178 to send New Channel packet to primary router.
5180 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * Added new function into the silcd/server.[ch] files:
5183 silc_server_create_new_channel_with_id to create new channel with
5184 already existing Channel ID.
5186 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5187 lib/silccore/silcpacket.h. This packet is used t send list of
5188 Set Mode payloads inside one packet. Server uses this to set
5189 the modes for the channels and clients on those channels, that it
5190 announced to the router when it connected to it. The protocol
5191 specification has been updated accordingly.
5193 * The silc_server_new_channel did not handle the packet coming
5194 from normal server as it normally does not send that. However,
5195 when it announces its channels it does send it. Implemented
5196 the support for that.
5198 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5199 into the file lib/silccore/id.h.
5201 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5203 * Fixed memory leaks in the functions silc_idlist_del_client,
5204 silc_idlist_del_channel and silc_idlist_del_server in the file
5205 silcd/idlist.c. All of those leaked like a sieve.
5207 * Fixed some small memory leaks in the client's function
5208 silc_client_notify_by_server.
5210 * Added functions into silcd/server.c: silc_server_announce_clients,
5211 silc_server_announce_channels and silc_server_announce_server.
5212 These functions are used by normal and router server to announce
5213 to its primary router about clients, channels and servers (when
5214 router) that we own. This is done after we've connected to the
5217 These functions effectively implements the following packet types:
5218 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5219 and SILC_PACKET_NEW_ID_LIST.
5221 * Added new functions into the silcd/packet_receive.[ch]:
5222 silc_server_new_id_list, silc_server_new_channel_list and
5223 silc_server_new_channel_user_list to handle the incoming
5224 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5226 * Added support of changing Channel ID in the function
5227 silc_server_replace_id. If the server that announces a channel
5228 to the router already exists in the router (with same name but
5229 with different Channel ID), router is responsible to send
5230 Replace ID packet to the server and force the server to change
5231 the Channel ID to the one router has.
5233 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5234 client that the Channel ID has been changed by the router. The
5235 normal server sends this to the client. Client must start using
5236 the new Channel ID as the channel's ID.
5238 Implemented handling of this new type into lib/silcclient/client.c
5239 into the function silc_client_notify_by_server.
5241 * Added new function silc_idlist_replace_channel_id into the files
5242 silcd/idlist.[ch] to replace the Channel ID.
5244 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5246 * Call silc_server_command_identify_check always when processing
5247 the IDENTIFY command in silcd/command.c
5249 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5252 send keepalive packets. The packet can be sent by clients,
5253 servers and routers.
5255 Added function silc_socket_set_heartbeat into the file
5256 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5257 If not set, the heartbeat is not performed. The actual
5258 heartbeat is implemented in the low level socket connection
5259 library. However, application is responsible of actually
5262 Added silc_server_send_heartbeat to send the actual heartbeat
5263 packet into silcd/packet_send.[ch]. Server now performs
5264 keepalive with all connections.
5266 * Added silc_task_get_first function into lib/silcutil/silctask.c
5267 to return the timeout task with shortest timeout. There was a bug
5268 in task unregistration that caused problems. TODO has been
5269 updated to include that task system must be rewritten.
5271 * The client library will now resolve the client information when
5272 receiving JOIN notify from server for client that we know but
5273 have incomplete information.
5275 * Rewrote parts of silc_server_remove_from_channels and
5276 silc_server_remove_from_one_channel as they did not remove the
5277 channel in some circumstances even though they should've.
5279 * Encryption problem encountered in server:
5281 The LEAVE command used to send the Channel Key packet to the
5282 router immediately after generating it. However, the code
5283 had earlier sent Remove Channel user packet but not immediately,
5284 ie. it was put to queue. The order of packets in the router
5285 was that Channel Key packet was first and Remove Channel User
5286 packet was second, even though they were encrypted in the
5287 reverse order. For this reason, MAC check failed. Now, this
5288 is fixed by not sending the Channel Key packet immediately but
5289 putting it to queue. However, this is more fundamental problem:
5290 packets that are in queue should actually not be encrypted
5291 because packets that are sent immediately gets encrypted
5292 actually with wrong IV (and thus MAC check fails). So, packets
5293 that are in queue should be encrypted when they are sent to
5294 the wire and not when they put to the queue.
5296 However, the problem is that the current system has not been
5297 designed to work that way. Instead, the packet is encrypted
5298 as soon as possible and left to the queue. The queue is then
5299 just purged into wire. There won't be any fixes for this
5300 any time soon. So, the current semantic for packet sending
5303 o If you send packet to remote host and do not force the send
5304 (the packet will be in queue) then all subsequent packets to the
5305 same remote host must also be put to the queue. Only after the
5306 queue has been purged is it safe again to force the packet
5309 o If you send all packets immediately then it safe to send
5310 any of subsequent packets through the queue, however, after
5311 the first packet is put to queue then any subsequent packets
5312 must also be put to the queue.
5314 Follow these rules and everything works fine.
5316 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Added new function silc_server_remove_clients_by_server to
5319 remove all client entries from ID list when the server connection
5320 is lost. In this case it is also important to invalidate all
5321 client entires as they hold the invalid server entry. This
5322 fixes fatal bug when server has lost connection and will reconnect
5325 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Made some sanity checks to silc_server_daemonise like to check
5328 whether the requested user and group actually exists.
5330 * Added sanity check to SKE's silc_ske_responder_finish to check
5331 that the public and private key actually is valid.
5333 * Invalidate the client's nickname when receiving Replace ID
5334 packet and the Client ID is being replaced. This means that the
5335 server will query the nickname if someone needs it (client)
5338 * Sort the ID Cache in client library when the ID Cache data
5339 has changed (needs sorting).
5341 * Do not allow for SILC client to create several connections to
5342 several servers. The client does not support windows right now
5343 and generating multiple connections causes weird behaviour.
5345 Irssi-silc client does support windows and can handle several
5346 connections without problems, see: www.irssi.org and SILC plugin.
5348 * Fixed some places where client was added to the IDList. The
5349 rule of thumb is following (in order to get everything right):
5350 If the client is directly connected local client then the
5351 `connection' argument must be set and `router' argument must be
5352 NULL to silc_idlist_add_client function. If the client is not
5353 directly connected client then the `router' argument must
5354 bet set and the `connection' argument must be NULL to the
5355 silc_idlist_add_client function.
5357 * The funtion silc_server_packet_send_local_channel actually did
5358 not check whether the client was locally connected or not. It
5359 does that now. Fixed a bug related to LEAVE command.
5361 * Fixed Remove Channel User payload parsing bug in server's
5362 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5364 * The server's silc_server_save_channel_key now checks also the
5365 global ID list for the channel as it might not be in the local
5366 list. Fixed a bug related to LEAVE command.
5368 * Is this the end of the [<unknown>] buglet that has been lurking
5369 around for a long time? A little for loop fix in server's
5370 silc_server_command_whois_parse that is used by both IDENTIFY
5371 and WHOIS command. At least, this was a clear bug and a cause
5372 of one type of [<unknown>] buglet.
5374 * WHOIS and IDENTIFY commands call the function
5375 silc_server_command_[whois/identify]_check function even if
5376 we are not router server.
5378 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Added --with-gmp configuration option. If set the GMP
5381 is always compiled in the SILC source tree. If not set then
5382 it is checked whether the system has the GMP3 installed. If
5383 it has then the GMP won't be compiled (the system's headers
5384 and library is used), if it doesn't have it then the GMP is
5385 compiled in the SILC source tree.
5387 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Changed RSA private exponent generation to what PKCS #1
5390 suggests. We try to find the smallest possible d by doing
5391 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5392 not security fix but optimization.
5394 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Added new config entry [Identity] to fork the server and run
5397 it as specific user and group. A patch from Bostik.
5399 * Imported Dotconf configuration library into lib/dotconf.
5400 This will be used to create the SILC configuration files later.
5401 It will appear in the distsribution after this commit.
5403 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5405 * A big code auditing weekend happening. Auditing code for
5406 obvious mistakes, bugs and errors. Also, removing any code
5409 Removed files for being obsolete:
5411 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5412 inline in the file lib/silcutil/silcbuffer.h)
5414 o lib/silcutil/silcbufutil.c (the header has inline versions)
5416 Changed code to fix possible error conditions:
5418 o The buffer formatting routines now check that the destination
5419 buffer really has enough space to add the data. This applies for
5420 both buffer formatting and unformatting
5421 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5422 unformatting was changed to accomodate following rules:
5423 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5424 sent to the function while XXX_*STRING will not allocate or copy
5425 the data into the buffer. Instead it sets the pointer from the
5426 buffer into the pointer sent as argument (XXX_*STRING used to
5427 require that the pointer must be allocated already). This change
5428 makes this whole thing a bit more consistent and more optimized
5429 (note that the data returned in the unformatting with XXX_*STRING
5430 must not be freed now). The routines return now -1 on error.
5432 o Tried to find all code that use buffer_format and buffer_unformat
5433 and added return value checking to prevent formatting and
5434 especially unformatting errors and possible subsequent fatal
5437 o Changed ske->x and ske->KEY to mallocated pointers in
5438 lib/silcske/silcske.h. Fixed possible data and memory leak.
5440 o Added return value checking to all *_parse* functions. Fixed
5441 many memory leaks as well.
5443 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5444 so that buffer overflows would not happen. All code now also
5445 checks the return value as it can fail.
5447 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * Added reconnection support to server if the normal server looses
5450 its connection to the router (for example if router is rebooted).
5451 The server performs normal reconnection strategy implemented
5452 to the server. Affected file silcd/server.c.
5454 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Added new packet type SILC_PACKET_SET_MODE that is used to
5457 distribute the information about changed modes (for clients,
5458 channels and clients channel modes) to all routers in the
5459 network. Updated the protocol specification accordingly.
5461 Added functions into silcd/packet_send.c and
5462 silcd/packet_receive.c: silc_server_send_set_mode,
5463 silc_server_set_mode.
5465 Added new files silcmode.[ch] into lib/silccore that implements
5466 the encoding and decoding of Set Mode Payload. Added new type
5467 SilcSetModePayload. Moved the definitions of different modes
5468 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5470 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5472 * Oops, a little mistake in server's connection authentication
5473 protocol. The protocol is not ended with FAILURE but with
5474 SUCCESS if the authentication is Ok. :) Affected file is
5477 * Implemented NICK_CHANGE notify handling in server in the file
5478 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5479 the local clients on the channel. After the changing nickname
5480 in router environment snhould work and the [<unknown>] nickname
5481 should appear no more.
5483 The silc_server_replace_id function that receives the Replace ID
5484 payload now sends the NICK_CHANGE notify type also in the file
5485 silcd/packet_receive.c
5487 * Changed WHOIS and IDENTIFY command to support the maximum amount
5488 of arguments defined in protocol specs (3328 arguments). This
5489 fixed a bug that caused problems when there were more than three
5492 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * Added extra parameter, command identifier, to the
5495 silc_client_send_command so that explicit command identifier
5498 Changed that ID list routines uses specific command identifier
5499 when sending WHOIS/IDENTIFY requests to the server so that they
5500 can be identified when the reply comes back.
5502 Affected files lib/silcclient/command.[ch],
5503 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5505 * Added `sender' argument to silc_server_packet_send_to_channel
5506 to indicaet the sender who originally sent the packet to us
5507 that we are now re-sending. Ignored if NULL. Affected file
5508 silcd/packet_send.[ch].
5510 * Added some server statistics support in silcd/server_internal.h
5511 SilcServerStatistics structure and around the server code. Also
5512 send some nice statistics information when client is connecting
5515 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Fixed channel ID decoding in server's JOIN command reply in
5518 silcd/command_reply.c
5520 * Fixed braodcasting of replace ID payload to not to send it if
5521 we are standalone server in silcd/packet_receive.c.
5523 * Fixed all channel message sending routines to not to send
5524 packets to clients that has router set, since they are routed
5525 separately in the same function earlier. Affects file
5526 silcd/packet_send.c and all channel packet sending functions.
5528 * In USERS reply, res_argv[i] are not allocated, the table
5529 is allocated. Thus changed that free the table, not its
5532 * In server's whois_check and identify_check if the client is
5533 locally connected do not send any WHOIS commands - they are not
5536 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Fixed some minor bugs in client when sending WHOIS command. The
5539 arguments was in wrong order.
5541 * Removed statis function add_to_channel from server in
5542 silcd/command.c that was previously used with the joining but
5545 * Tested USERS command in router environment successfully with two
5546 routers, two servers and two clients.
5548 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5550 * Reorganized the USERS command and command reply in client library
5551 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5552 When the command is given by user we register a pending command
5553 callback that will reprocess the command after the reply has been
5554 received from the server. When reprocessing the packet we then
5555 display the information. Thus, the USERS information is displayed
5556 now in the command callback instead of in the command reply
5557 callback. The processing of the command is same as previously
5558 when server has sent the command reply in the JOINing process.
5560 * Added to USERS command in silcd/command_reply.c to join the client,
5561 we didn't use to know about, to the channel after we've created
5562 a client entry for it. Also, for clienet we did know already still
5563 check whether it is on the channel or not and add it if not.
5565 * Removed silc_server_command_join_notify as the function and its
5568 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5570 * Changed the client's pending command handling to the same as the
5571 server's pending command handling. It is also now possible to
5572 execute command reply functions from other command reply
5573 function as the function callbacks for commands and command
5574 replies are one and same. The pending commands are not static
5575 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5576 in client connection context. Thus, pending commands are server
5577 connection specific as it is convenient.
5579 Changed the function silc_client_command_pending and
5580 silc_client_command_pending_del and added new function
5581 silc_client_command_pending_check. Removed the
5582 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5585 * Added cmd_ident, current command identifier, to the client
5586 connection context in lib/silcclient/client.h to keep track on
5587 command identifiers used in command sending. Client's command reply
5588 function handling now supports the mandatory command identifiers.
5590 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5591 funtions in client to fully support pending command callbacks.
5593 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5594 as one of the arguments to the application in the command reply
5597 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5598 before first releasing SILC but came back. Now it is removed again
5599 and should come back nomore. The FORWARDED flag was used only
5600 by the JOINing procedure by forwarding the command packet to router.
5601 Now, the JOINing procedure has been changed to more generic (due
5602 to various router environment issues) and FORWARDED is not needed
5603 anymore for anything. The protocol specification is yet to be
5606 Now, removed silc_server_packet_forward from server and the flag
5607 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5609 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Renamed NAMES command to USERS command. The NAMES was named that
5612 due to historical reasons. Now it is renamed. Also, rewrote
5613 parts of the USERS command. The nickname list is not sent anymore
5614 by the server. Only Client ID and mode lists are sent in the USERS
5615 command. Changed this also to the protocol specification.
5617 The client now resolves the names and stuff after it receives
5618 the USERS list from the server when joining to the channel.
5620 * WHOIS and IDENTIFY commands has been changed to support multiple
5621 Client ID's per command. One can now search for multiple users
5622 in the network by sending only one WHOIS or IDENTIFY command.
5623 Changed the code and the protocol specifications.
5625 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5626 uses silc_server_command_whois_parse to parse the request. */
5628 * If normal server, do not parse the WHOIS and IDENTIFY requests
5629 before sending it to the router. Saves some time.
5631 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Fixed JOIN command on client library. Wrong number of arguments
5634 used to crash the client.
5636 * Added silc_server_channel_has_global function to check whether
5637 channel has global users or not.
5639 * Added silc_server_channel_has_local function to check whether channel
5640 has locally connected clients on the channel.
5642 * The silc_server_remove_from_one_channel now checks whether the
5643 channel has global users or not after given client was removed from
5644 the channel. It also checks whether the channel has local clients
5645 on the channel anymore. If it does not have then the channel entry
5646 is removed as it is not needed anymore.
5648 * The silc_server_notify now checks on JOIN notify whether the joining
5649 client is one of locally connected or global. If it is global then
5650 the channel has now global users on the channel and that is marked
5651 to the channel entry. Also, it now saves the global client to
5652 global list who is joining and JOINs it to the channel. This is
5653 for normal server, that is.
5655 Changed silc_server_send_notify_on_channel,
5656 silc_server_packet_relay_to_channel and
5657 silc_server_packet_send_to_channel check if we are normal server
5658 and client has router set (ie. global client) do not send the
5659 message to that client, as it is already routed to our router.
5661 * Implemented LEAVE notify type handling in silc_server_notify
5664 * Tested LEAVE command in router environment successfully. Tested
5665 with two routers, two servers and two clients.
5669 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5671 * Implemented SIGNOFF notify type handling in silc_server_notify
5674 * silc_server_remove_id now removes the client entry from all channels
5675 it has joined and thusly sends SIGNOFF notify type.
5677 * Rewrote the NAMES list generation in server by removing two excess
5678 loops. The lists are created now inside one loop.
5680 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5682 * silc_server_remove_channel_user checks now also global list
5683 for channel and client.
5685 * silc_server_new_channel_user checks now both local and global
5686 list for channel and client. Fixed a bug in client id decoding.
5687 Used to decode wrong buffer.
5689 * silc_server_channel_message checks now both local and global
5690 list for channel entry.
5692 * Tested channel joining (hence JOIN) in router environment
5693 successfully. Tested with two routers, two servers and two
5696 * Tested channel message sending in router environment successfully.
5698 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Added silc_server_save_channel_key into server.[ch] to save the
5701 received channel key in Channel Key payload processing. It is
5702 also used in JOIN command reply handling.
5704 Equivalent function silc_client_save_channel_key added into
5705 client.[ch] into client library.
5707 * Changed JOIN command reply to send information whether the channel
5708 was created or not (is existing already) and the channel key
5709 payload. Changed protocol specs accordingly.
5711 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5712 the request was sent by ID and not by nickname. Crashed on
5715 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5717 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5718 now correctly save the received data.
5720 * silc_server_free_sock_user_data now notifies routers in the
5721 network about entities leaving the network.
5723 At the same time implemented functions silc_server_remove_id
5724 and silc_server_send_remove_id to receive and send REMOVE_ID
5725 packets. The packet is used to notify routers in the network
5726 about leaving entities. The ID removed will become invalid in
5729 * Added function silc_idlist_del_server into server. Removes and
5730 free's server entry from ID list.
5732 * silc_server_private_message function now checks, if we are router,
5733 that the destination ID really is valid ID, naturally.
5735 * In router when NEW_ID packet is received (for new client) the
5736 hash of the Client ID is saved in the ID Cache but the
5737 client->nickname is set to NULL, instead of putting the hash
5740 IDENTIFY command now also checks that client->nickname must be
5741 valid. If it is not if will request the data from the server who
5742 owns the client. Added new function
5743 silc_server_command_identify_check.
5745 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5746 to set the command to already allocated Command Payload.
5748 * Tested private message sending in router environment with two
5749 routers, two servers and two clients. Fixed minor bugs and now
5752 * Fixed segfault from client's NAMES command. Used to crash if
5755 * Forwarded packets must not be routed even if it is not destined
5756 to the receiver. Changed server code comply with this.
5758 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Added `require_reverse_mapping' boolean value to ServerParams
5761 structure. If TRUE (not default) the server will require that
5762 the connecting host has fully qualified domain name.
5764 If the reverse mapping is not required and hostname could not be
5765 found the IP address is used as hostname.
5767 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * Implemented version string checking to both client and server.
5770 The check is incomplete currently due to the abnormal version
5771 strings used in development version of SILC.
5773 * Changed all command functions in server to use the new
5776 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Changed char *data to unsigned char *data in ID Cache system to
5779 support binary data as ID Cache data. Changed code to support
5780 binary data in lib/silccore/idcache.c.
5782 * Renamed silc_server_packet_relay_command_reply to
5783 silc_server_command_reply as it is normal packet receiving
5784 function. Rewrote the function to accept command replys for
5785 servers and not only for clients.
5787 * Mark remote router always as registered server if we are connecting
5788 to it. Otherwise, commands sent by the router to us are ignored.
5790 * All ID List find routines now returns the ID Cache Entry pointer
5791 as well if requested.
5793 * WHOIS command works now in router environment, tested with two
5794 routers, two servers and two clients.
5796 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5797 in router environment (as it is almost equivalent to WHOIS) but
5798 hasn't been tested thoroughly. Added new functions:
5800 silc_server_command_identify_parse
5801 silc_server_command_identify_send_reply
5802 silc_server_command_identify_from_client
5803 silc_server_command_identify_from_server
5805 * Disabled route cache adding because adding two different ID's with
5806 same IP replaces the old cache entry thus giving wrong route.
5807 The entry->router->connection is always the fastest route anyway
5808 so route cache may not be needed. Of course, new routes maybe
5809 established after receiving the ID when the entry->router->connection
5810 might not be anymore the most optimal.
5812 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Add route cache for received ID for fast routing.
5816 * Added silc_server_packet_route to route received packet on router
5817 that is not destined to us.
5819 * Renamed silc_server_get_route to silc_server_route_get.
5821 * Added id_string and id_string_len fields into SilcServer to
5822 include encoded ServerID for fast comparing without excess
5823 encoding of the ID's.
5825 * Cleaned up WHOIS command on server side. Added following static
5828 silc_server_command_whois_parse
5829 silc_server_command_whois_check
5830 silc_server_command_whois_send_reply
5831 silc_server_command_whois_from_client
5832 silc_server_command_whois_from_server
5834 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5835 arguments in command replies. All command functions should be
5836 updated to use this macro.
5838 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * Minor typo fixes on command reply handling on server.
5842 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5844 * Added silc_server_command_add_to_channel internal routine to add
5845 the client to the channel after router has created the channel and
5846 sent command reply to the server.
5848 * Added generic silc_server_send_command to send any command from
5851 * Use static buffer with ID rendering instead of duplicating data.
5853 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Fixed a channel user mode bug when joining to a channel server gave
5856 everybody channel founder rights, oops.
5858 * We mark ourselves as the router of the incoming server connection
5859 if we are router ourselves. This way we can check in some packet
5860 sending functions whether it is locally connected server. For
5861 incoming router connections we put NULL.
5863 * For router sending packets locally means now always sending the
5864 packet cell wide; to local clients and local servers. For normal
5865 server sending packet locally means sending it to only local
5868 * Fixed the JOIN command to really work in router environment. If the
5869 channel is created it is always created by the router. Router is
5870 also responsible of making the initial joining to the channel,
5871 sending JOIN notify to the sending server and distributing
5872 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5873 does not exist server doesn't do anything else but forward the
5874 command to the router which performs everything.
5876 * Added silc_server_send_channel_key function to send the Channel Key
5879 * Added silc_server_create_channel_key to create new channel key. The
5880 channel key is now re-generated everytime someone joins or leaves
5881 a channel, as protocol dictates. Note: channel->key_len is the
5884 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5887 packet_receive.[ch] to separate packet sending and receiving
5888 routines. The server.[ch] now includes everything else including
5889 actual packet processing (writing and reading data) and other
5892 Renamed silc_server_private_message_send_internal to
5893 silc_server_send_private_message. The routine is still though
5894 used only to relay private messages as server does not send
5895 private messages itself.
5897 Renamed silc_server_new_channel to silc_server_create_new_channel
5898 and added new function sicl_server_new_channel that handles the
5899 incoming New Channel packet. Added also new sending function
5900 silc_server_send_new_channel to send New Channel Payload.
5902 * Added new function silc_server_notify to process incoming notify
5903 packet to the server/router. Server may then relay the notify
5904 to clients if needed.
5906 * Added new function silc_server_new_channel_user to process incoming
5907 New Channel User packet. Router will redistribute the packet and
5908 send JOIN notify to its local clients and locally connected servers
5909 if needed. Normal server will send JOIN notify to its local client
5910 on same channel when received this packet. Added also corresponding
5911 sending function silc_server_send_new_channel_user to sent the
5914 * Added boolean route argument to send_notif_to_channel and
5915 packet_send_to_channel functions to attempt to route the packet
5916 if it is TRUE and send only locally if it is FALSE.
5918 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * silc_server_replace_id now broadcasts the received replace ID
5921 packet if it is not broadcast packet already. The router must
5922 broadcast to inform other routers about changed ID.
5924 * Added backpointer to server's router into SilcServer context in
5925 silcd/server_internal.h.
5927 * Fixed silc_server_packet_broadcast to send correct broadcast
5930 * The channel key is now distributed to the local client as soon
5931 as it is received from the router (in router environment) so that
5932 no other packet may be sent for the channel until client has
5935 * silc_server_remove_channel_user now broadcasts the received
5936 Remove Channel User packet if it is not broadcast packet already.
5937 The router must broadcast to inform other routers about removed
5940 * Added users field into SilcPacketContext that is a reference count
5941 of the context. One can increase the reference count by calling
5942 silc_packet_context_dup which is now changed to just increase the
5943 reference count instead of duplicating the data. The reference
5944 count is decresed by calling silc_packet_context_free that will
5945 free the data after the reference count hits zero.
5947 For now on the packet context and everything allocated into it
5948 (including the raw packet from network) must be freed by calling
5949 the new silc_packet_context_free function. Added also new function
5950 silc_packet_context_alloc that must be used now to allocate the
5951 context. This also means that if a routine is asynchronous from
5952 silc_[client/server]_packet_parse_type the packet context must
5953 be duplicated by calling silc_packet_context_dup. Otherwise it
5954 gets free'd after silc_[client/server]_packet_parse_type returns.
5955 Also, one must remember that if packet is duplicated then its
5956 reference count must be decresed by calling the free function as
5957 many times as it was duplicated.
5959 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5960 from both client and server.
5962 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5964 * Made joining to a channel working in router environment.
5966 * Cleaned up JOIN command on server side and create function
5967 silc_server_command_join_channel internal routine to make the
5970 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Changed silc_command_pending list to SilcDList. Also, added
5973 `ident' field to SilcServerCommandPending structure to identify
5974 the reply and to call correct callback.
5976 Added silc_server_command_pending_check function to replace the
5977 corresnponding macro. The silc_command_pending list is not
5980 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5981 to set identifier to previously allocated Command Payload. It
5982 is used to set identifier for command when resending Command
5985 * Added silc_command_payload_encode_payload to encode Command
5986 Payload buffer from SilcCommandPayload structure.
5988 * Added silc_argument_payload_encode_payload to encode Argument
5989 payload buffer from SilcArgumentPayload structure.
5991 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5993 * Changed WHOIS command to support router connection on server side.
5994 The whois request is always sent to router unless the server is
5995 standalone server. After server has received the reply from the
5996 router will it send the reply to the client.
5998 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5999 broadcast received broadcast packet. The function is used only
6000 by router. The broadcast packet is always sent to the router's
6003 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6004 render given ID to printable string, for log files for example.
6006 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Made basic router to router connections working. At least they
6009 can now connect to each other but nothing really works the way
6010 they are supposed - yet.
6012 * Added new initiator token to RouterConnection configuration
6013 file in silcd/serverconfig.[ch]. It is used to tell whether we
6014 are the initiator to the remote router or whether we'll expect
6015 the other end to connect.
6017 * Moved registering of listener task to silc_server_init, hence
6018 the server starts listenning as soon as it is run, even if it
6019 does not have connections to other routers. Let's see how well
6022 * Changed default connection retry timeouts for more suitable in
6025 * Removed cipher and such arguments from silc_idlist_add_client
6026 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6027 Added new function silc_idlist_add_data to add the keys and stuff
6030 * Added SilcIDListData structure and added it to SilcClientEntry
6031 and SilcServerEntry as their first field in the structure. This
6032 way we can explicitly cast the ID entries to the SilcIDListData
6033 structure and get common data for the entries. In past, we had
6034 to first check what type of connection it is and then cast it to
6035 correct ID entry type. Now, we can directly cast the opaque
6036 pointer to the SilcIDListData (no matter what ID entry it actually
6037 is) and get the data needed.
6039 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6042 in some circumstances even if threre were timeout tasks, though not
6043 IO tasks, but tasks anyway. Now fixed.
6045 * Defined SilcServerConnection structure to hold connection specific
6046 stuff about directly connected servers and routers. The definition
6047 is currently in silcd/server_internal.h. I thought about having
6048 a bit more important role fro this struct but for now it is used
6049 only when connecting to other server (or router actually).
6051 * Added connecting retry support in server when connecting to
6052 router(s). The retry feature implement exponential backoff
6053 algorithm. Also, added SilcServerParams structure to hold default
6054 parameters for server. For now, it include these retry settings
6055 and are hard coded. After server is moded to be as Silc Server
6056 Library this structure will be more important.
6058 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * Changed client librarys channel->clients table to SilcList and
6061 changed code accordingly.
6063 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6065 * Changed client's channel table to SilcList and changed code
6066 accordingly. Also changed SilcChannelClientEntry to include back-
6067 pointer to the channel so that client entry can use that structure
6068 as list as well and we have fast cross-reference to the channel.
6069 This change dramatically decreased the complexity of channel
6070 handling with client entry and vice versa (removed one extra
6071 loop when searching for channel entry from many functions).
6073 * Changed server->sim from table to SilcDList and changed code
6076 * NAMES command can now be used from user interface. It will show
6077 the user list on the channel, neatly.
6079 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6080 Code now saves realname of the user if it becomes available.
6082 * Renamed configure.in to configure.in.pre and made ./prepare
6083 script to automatically add correct version string to
6084 configure.in which it creates from configure.in.pre.
6086 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * NAMES command reply now shows users mode with the nickname when
6091 * Moved silc_client_ch[u]mode[_char] functions from
6092 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6093 place sucks, they are utility functions and should be in some
6096 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6098 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6101 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Added TRQ (efficient deque and list library) into lib/trq. This is
6106 a very good list library that is currently used in the SILC. Defined
6107 SilcList API over the library because I didn't like the API very
6108 much. See lib/trq/silclist.h for the API and examples of how to
6109 use the API. Fixed various places in the code to use the new
6110 SilcList API. The SilcList is meant for lists that has a structure
6111 already defined as a list. It is not suitable to add just some
6112 context to the list (in TRQ, the context is the list actually).
6114 So, I defined SilcDList that can be used for the purpose where
6115 predefined list structure does not exit. This can be used as
6116 such list. Now some context just can be added to the SilcDList.
6117 Currently this list is not used in the SILC just yet, though there
6118 are a lot places where this can replace dynamically allocated
6119 tables and I will fix these places, later, to use SilcDList.
6120 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6121 and use TRQ internally).
6123 Also fixed some annoying warning messages that the original TRQ
6124 code generated. Also minor changes to TRQ's Makefile.in.
6126 * Added support for querying by Client ID to both WHOIS and
6127 IDENTIFY commands into server, as required by the protocol.
6129 * Removed method function pointers from SilcBuffer structure. They
6130 weren't used to anything and just increased the context size for
6131 no good reason. This change also made silc_buffer_alloc and
6132 silc_buffer_free functions inline functions.
6134 * Disabled command flooding detection support until it's fixed so
6135 that it accepts commands in but does not execute them more than once
6138 * Added silc_net_localhost(), to return local hostname, into
6139 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6140 that must be initialized before calling silc_client_init.
6142 * Added new function: silc_server_send_notify_on_channels to send
6143 notify messages to all channels client has joined. It is assured
6144 that the message is sent only once per client.
6146 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6147 lib/silcutil/silcutil.[ch] as silc_format function. The new
6148 function is generic and is used by server as well, not only by
6149 the logging routines.
6151 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6152 the provided version string was not acceptable. Added new function:
6153 silc_ske_check_version into lib/silcske/silcske.h. The function
6154 must be implemented by the application (client or server) and it
6155 does not reside in the SKE library. The function checks the version
6156 string remote end sent.
6158 * Added back pointers (to opaque context and to SilcSocketConnection)
6159 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6161 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6162 duplicate packet context structure.
6164 * Changed `notify' client operation to send same arguments as client
6165 receives from server except for ID's. ID's are mapped to correct
6166 ID entry and that is returned. Also, if channel entry is not sent
6167 by server but the notify is for channel the channel entry is sent
6168 to application (otherwise application doesn't know that it is for
6169 channel (library gets it from packet's Destination ID)).
6171 * Added silc_client_remove_from_channels into client library to
6172 remove a client from all channels it has joined to. Used when
6173 received SIGNOFF notify from server. Added also new function
6174 silc_client_replace_from_channels to replace old ID entry with
6175 new ID entry on all channels. Used when received NICK_CHANGE
6178 * Fixed ID Cache list handling in silc_idlist_get_client in
6179 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6180 to get (or query) client by ID.
6182 * Updated TODO list.
6184 * Added connection authentication status message defined by the
6185 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6186 support for these into the code in client and server side.
6188 * Added generic function silc_client_send_command to send any command
6189 with variable argument list. Application should use this function
6190 to send commands if the command functions provided by the library
6191 does not suite for the application's user interface needs.
6193 * Added new `failure' client operation. Application is notified about
6194 received failure packet if client is executing a protocol. In this
6195 case the protocol's execution has failed.
6197 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6198 is required by the protocol.
6200 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6201 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6204 * Added status flag to SilcSKE object to indicate realtime status
6205 of the SKE protocol.
6207 * Application receives now exactly same command reply arguments as
6208 the library receives from server. However, if ID is received the
6209 corresponding ID entry is returned to the application (eg. Client
6210 ID is mapped to correct SilcClientEntry entry and that is returned).
6211 Changed command_reply client operation due to this change.
6213 * Changed all ID's in commands and in command replys as ID Payloads.
6214 Change affected both client and server side codes.
6216 All ID's sent in SILC network (with execption of ID's in SILC
6217 Packet header) are sent in ID Payload to support variable length
6220 * Server now notifies nick changes and notifies all clients on
6221 the channels about the new nickname (about the new Client ID,
6224 * Implemented CMODE command to change channel modes. Supports all
6225 channel modes defined by the protocol specs except ban and invite
6226 lists. (Also, private channel key mode is supported but support for
6227 setting private channel key in client is missing, thus, this mode
6228 has no effect on client side (except that server requires that the
6229 client uses private channel key and normal channel traffic does not
6232 Also, invite mode works per se, but INVITE command does not work
6233 yet correctly, so you can set channel as invite only channel but
6234 inviting clients to the channel does not work (it is yet to be
6235 thought what's the best way to do it).
6237 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6238 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6239 Implemented CUMODE command to change user's mode on the channel.
6240 Supports all modes defined by the protocol specs.
6242 * Added NAMES command reply to return users modes on the channel.
6244 * Removed unnecessary and slow ciphers from lib/silccrypt.
6246 * Set SO_KEEPALIVE option to connection sockets by default.
6248 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6250 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6251 redefined the Notify Payload into protocol specs.
6253 * Added silc_id_payload_parse_id to get ID directly from raw
6256 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6258 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6259 accept searching by Client ID as well.
6261 * Added support for LEAVE and SIGNOFF notify types in client library.
6263 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6264 to parse ID Payload from raw data.
6266 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Added flags parameter into silc_ske_assemble_security_properties
6269 function in lib/silcske/silcske.[ch].
6271 * Changed notify client operation to fit better for notify messages
6272 sent by server. The notify payload received from server is now
6273 passed to the application (after parsing it to SilcNotifyPayload).
6274 It is application's responsibility to retrieve the arguments
6275 from the payload and show the message the way it wants. The message
6276 sent by server is implementation specific.
6278 * Changed public keys to comply with the protocol specification.
6279 Old public keys are not supported anymore and are not compatible.
6281 * Removed nickname from Channel Payload as the latest draft removed
6282 it. The client must resolve the nickname from the NAMES command
6283 reply received when it joined the channel.
6285 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6287 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6289 * Fixed some errors in protocol specification drafts.
6291 * Created lib/silccore/silcnotify.c to implement Notify Payload
6292 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6293 generic payloads described by protocol specifications. The file
6294 includes implementations for ID Payload and Argument Payload.
6296 * Changed Command Payload implementation to use the new Argument
6297 Payload. Changed command_xxxx_payload to command_payload_xxxx
6298 to comply with SILC coding conventions.
6300 * Added suppport for Argument Payload handling in Notify Payload
6301 implementation as protocol requires it. Added the new support
6302 into server and client lib as well.
6304 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6306 * Added support for multiple nicknames on same channel. [n] is
6307 added locally to the nickname if there are more than one same
6308 nicknames on the channel.
6310 * Server now sends all nicknames that matched WHOIS request.
6311 Client also shows the list received from server.
6313 * Added TOPIC command to client side. User can now set and show
6314 current topic on channel.
6316 * Added MOTD command to client and server. Also, server sends the
6317 motd when client connects to the server.
6319 * Changed version strings to comply ISO 8601.
6321 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * Fixed protocol error handling in client library. It should now
6324 cope even if the SKE fails for some reason.
6326 * Made new protocol specification drafts for submitting to IETF.
6328 * Implemented TOPIC command to server in silcd/command.c.
6330 * Added two new notify types into lib/silccore/silcnotify.h:
6331 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6332 notify nickname change and topic setting/change on a channel.
6334 * API change of command_reply operation in client library. The
6335 application gets now the status type received from server as well.
6337 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6339 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6341 * Cras fixed and optimized the packet handling even further and
6342 it should work now. Minor change to the prototype of function
6343 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6345 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Added new function into lib/silcutil/silcschedule.[ch]:
6348 silc_schedule_with_fd to select() a specified fd. The function
6349 returns after timeout expires or data arrives or goes. The
6350 function is used by packet routines to wait that all data is
6351 received from network.
6353 * Fixed data reading from network in lib/silccore/silcpacket.c.
6354 The code now assures that all data is read from the fd and then
6355 continues packet processing. This was a bug fix since the code
6356 used to drop some data in some circumstances.
6358 * Added new function into lib/silcclient/client.[ch]:
6359 silc_client_start_key_exchange to start key exchange after
6360 connection has been established to server. The code internally
6361 now uses this funtion but its main purpose was to provide it
6362 for applications that perform their own connecting. After
6363 application has created a connection it merely calls this
6364 function to start the key exchange between client and server.
6365 The library takes care of everything else after that.
6367 Updated also lib/silcclient/README to explain the usage of
6370 * Do not send to application information that connection has
6371 been established. Application gets notified it by connect
6374 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Applied cras's patch to add silc_schedule_one function. The
6377 function runs scheduler once and returns.
6379 * Fixed the scheduler after cras messed it up. The timeout
6380 handling works now as it's supposed to work.
6382 * Added into lib/silccore/ silcnotify.h to include notify
6383 message types support. Changed silc_server_send_notify*
6384 functions, in server.[ch], to support those new notify types.
6385 Added the support for the notify types into client library,
6386 as well. Added new notify client operation into ops.h in
6389 * Changed silc_server_packet_send_to_channel to send normal
6390 packets instead of just channel message packets. The function
6391 is now used to send the notify packets to channels. It is not
6392 used to send channel message packets anymore, as server never
6395 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6396 va_arg()s as it seems to require it nowadays. I guess, if SILC
6397 is compiled with older va_arg() the new code should work anyway.
6399 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6401 * Splitted core library. Core library (lib/silccore) includes
6402 now only SILC protocol specific core (and common) components.
6403 Created new utility library (lib/silcutil) that includes more
6404 generic purpose stuff. The stuff for util library was taken
6405 from the old core library. This was minor and easy split.
6407 * Created SILC Client Library (lib/silcclient) that includes
6408 implementation of the SILC client without user interface. This
6409 was major move from silc/ directory. The code has been changed
6410 so that it is transparent towards the user interface. The
6411 silc/ directory includes now the same user interface as before
6412 and it uses the new client library. Read lib/silcclient/README.
6413 Basicly, the client library performs everything else related
6414 to SILC except user interface handling. Also, configuration
6415 files are considered to be part of user interface and library
6416 does not handle them.
6418 This change also changed a lot of structures, function naming etc.
6419 Most important change was that SilcClientWindow object was
6420 renamed to SilcClientConnection in the client library. Created
6421 also new file lib/silcclient/ops.h. Also added new files
6422 silc/local_command.[ch] and silc/client_ops.[ch].
6424 All these changes were made to make it easier for user interface
6425 designers to create what ever user interface for the SILC client
6428 It is also expected that the server will be moved to lib
6429 directory as well and SILC Server Library will be created;
6430 sometimes in the future.
6432 * Removed Local commands from lib/silccore/silccommand.h as
6433 they are application specific and new client library does not
6434 handle any of those anymore.
6436 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6437 old client implementation in silc/.
6439 * Added support for callback functions in SILC_LOG_* macros.
6440 Application can now set its own callbacks that will be called
6441 instead of using the default functions that will always print
6442 the debug messages to stderr (or stdout). Also, debugging can
6443 now be disabled by setting silc_debug to FALSE and re-enabled by
6444 setting it to TRUE. Note, that logging will still work even
6445 if debugging is disabled.
6447 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6448 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6449 silc_log_reset_debug_callbacks.
6451 * To enable debugging in silc client one must give now -d
6452 option on command line.
6454 * Changed silc_schedule_init to automatically allocate task queues
6455 if they are not allocated before calling it.
6457 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6459 * Added GMP 3.1 into math library.
6461 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6463 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6464 a channel in SILC network. The packet is used by servers and
6465 routers to notify other routers that user has left a channel.
6466 This little feature was missing until now. Added the feature
6467 to protocol specification as well.
6469 Added functions: silc_server_send_remove_channel_user and
6470 silc_server_remove_channel_user into server.[ch].
6472 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6473 lib/silccore/silcpacket.h. However, they are not implemented
6476 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Fixed joining to a channel and sending channel messages
6479 between server and router. The channel message sending should
6480 now work inside a cell.
6482 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Fixed the private message sending between server and router.
6485 The private message sending should now work inside a cell.
6487 * Added silc_server_replace_id into server.[ch] to replace
6488 existing ID in the SILC network.
6490 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6491 and silc_idlist_replace_server_id into idlist.[ch] in server.
6493 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6495 * Fixed the server to server connections. Server can again now
6496 connect to router. Router to router connections probably does
6499 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6501 * Added dynamic protocol registering support. Now protocols can
6502 registered and unregistered on the fly. Patch by cras.
6504 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * Added lib/contrib directory to hold routines that some platforms
6507 don't have but are needed by SILC.
6509 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6510 into lin/contrib to provide getopt() and getopt_long() for
6511 those who don't have it.
6513 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6515 * Added AWAY command to client. When away message is set and
6516 client receives a private message packet the client automatically
6517 replies to the sender with the away message.
6519 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6520 bug seemed to be the cause of recent problems when compiling
6523 * Added version detection support to SKE protocol specification
6524 and added the new changes to the SKE implementation as well.
6525 There were other minor changes in the SKE protocol as well.
6527 Many changes in lib/silcske/silcske.[ch] and in
6528 lib/silcske/payload.[ch].
6530 * Added ^U functionality, clear input line. Patch from cras.
6532 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6534 * Mainly small bugfixes on core library. Fixed some debugging
6535 logging and buffer overflow in silclog.c.
6537 * Updated config.sub and config.guess on the distribution tree.
6539 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6541 * Added command lagging support in server. Client may execute
6542 commands now only once in two seconds.
6544 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6546 * Optimized packet reception. MAC computation and checking is now
6547 also more optimized. A lot previously duplicated code is now
6548 used as generic by both client and server.
6550 * Fixed key pair generation in clientutil.c
6552 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6554 * Added into lib/silccore/silcbufutil.[ch] new function;
6555 silc_buffer_realloc.
6557 * Moved generic packet sending/encryption functions to
6558 lib/silccore/silcpacket.[ch] from client and server. Some
6559 rewriting of the functions.
6561 * Moved all generic packet reception/decryption functions to
6562 lib/silccore/silcpacket.[ch] from client and server. The
6563 packet processing is now much cleaner in both client and server.
6564 These were major changes in both client and server.
6566 * Created many common functions in server to do packet sending.
6567 Previously code were duplicated a lot, this has been removed
6570 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6572 * Rewrote major parts of the ID cache system. Don't know
6573 whether it is better now or not but at least the API is more
6576 * Major rewrite on ID cache stuff on client because of the ID
6577 cache API changes. Added idlist.c to client.
6579 * Also major rewrite on ID cache stuff on server as well.
6580 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6581 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6582 in hand, instead they are all put into the ID cache system now.
6583 All server_idlist_* routines uses ID cache now instead of
6584 traversing its own lists (those lists does not exist anymore).
6585 SilcIDList though still exists. Also, SilcXXXEntry's are
6588 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Finally made the SKE implementation compliant to the protocol
6591 specification. All mp integers are now binary encoded as
6592 opposed being HEX encoded.
6594 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6597 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6598 functions: silc_[encode/decode]_pem. Also added function
6599 silc_encode_pem_file to PEM encode with newlines ('\n') for
6602 * SILC public keys are now encoded either PEM or binary. Same
6603 option is for private keys as well. By default private keys
6604 are binary encoded and public keys PEM encoded. Silly HEX
6605 encoding were removed.
6607 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6608 function to create fingerprints.
6610 * Fixed a bug in SHA1; does not change the original data anymore.
6612 * Partly implemented INFO command on client and server side.
6613 Fixed CLEAR command. Changes to SERVER command; show current
6614 server(s) when giving command without arguments. Added
6615 VERSION command to client.
6617 * Added check to server that unregistered connections cannot
6618 execute commands (unless it is specificly allowed).
6620 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Fixed screen refresh.
6624 * Fixed channel joining bug from client. On some circumstances
6625 client tried to join to a channel it had already joined.
6627 * Added public key verification process into client's protocol.c.
6628 The client now verifies the public key from user and saves
6629 it into ~./silc/serverkeys/ directory.
6631 Added into: clientutil.[ch]: silc_client_verify_server_key.
6633 * Changed SKE protocol's silc_ske_initiator_finish function
6634 to accept callback function that verifies the received public
6635 key. Removed old silc_ske_verify_public_key function.
6637 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6639 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6640 silc_pkcs_private_key[_data]_set.
6642 * Made the password and public authentication more cleaner in
6643 server's protocol.c.
6645 * Removed historic and obsolete protocol `channel_auth' from
6646 both client and server.
6648 * Removed wrong way of sending command status messages from
6649 server to client in server's command.c. The old way violated
6650 protocol specification.
6652 Changes to silccore/silccommand.[ch]: removed
6653 silc_command_encode_status_payload -> not needed anymore,
6654 changed silc_command_encode_payload_va to accept extra
6655 argument on variable argument list. The argument type must
6656 now be provided to the function. Also, added new function:
6657 silc_command_encode_reply_payload_va which is same as
6658 normal command_encode_payload_va except command status type
6659 is provided as extra argument.
6661 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Added ~./silc directory handling. The directory includes the
6664 public and private keys for the client.
6666 Added silc_client_check_silc_dir, silc_client_create_identifier
6667 and silc_client_load_keys.
6669 * Implemented SILC protocol compliant public key. Added public
6670 and private key saving to and loading from files.
6672 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6673 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6674 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6675 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6676 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6678 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6679 silc_pkcs_load_[public/private]_key.
6681 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6683 * Added silc_server_get_route (route.[ch]) to get connection
6684 data for the fastest route for given ID.
6686 * Implemented INVITE command on client and server. The command
6687 were re-defined in the SILC Protocol Specification and the
6688 implementation now complies with the specification.
6690 * Implemented PING command on client and server.
6692 * Implemented NAMES command on client and server. The server side
6693 supports currently only normal server not router server yet.
6694 Some changes to NAMES definition in SILC protocol specification.
6696 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6698 * Implemented LEAVE command on client and server.
6700 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6701 again. This change was made to the protocol as well. Server
6702 should not violate the protocol specification anymore.
6704 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6706 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6707 was tested. SOCKS4 was not but should work anyway.
