3 * Simple handling of TERM and HUP signals. Also added some log
4 flushing call around. Affected file is
7 * Fixed small bugs in silclog.c. Now buffering output will take
8 effect after 10 seconds since startup: This will ensure that
9 no important startup messages are lost. Also output redirection
10 will preserve original format ([Date] [Type] message).
11 Affected file is lib/silcutil/silclog.c.
13 * Added two options to the config file, in the logging section:
14 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
15 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
17 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
19 * Do not print the warning about log files not being initialized
20 more than once to avoid excess logging. Affected file is
21 lib/silcutil/silclog.c.
23 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
24 the SIM copying in make install in Makefile.am.pre.
26 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
28 * Rewritten silclog APIs. Globally interesting changes follows:
29 silc_log_set_files() changed to silc_log_set_file().
30 silc_log_set_callbacks() changed to silc_log_set_callback().
31 ROBOdoc documented silclog header file.
32 SilcLogCb now returns bool to wether inihibit the default
33 handler or not (to keep the old behaviour return always TRUE).
34 The new APIs should also fix the problem of the
35 silcd_error.log file that was written in the current directory.
38 Log files streams will remain opened after silc_log_set_file()
39 call, means less CPU usage notably on high traffic servers.
40 File streams are now full buffered, and flushed to the disk
41 every 5 minutes, lesses HD activity and CPU usage.
42 Messages can be redirected, allowing admins to configure
43 one single logfile for all server messages.
44 the silc_log_quick global variable to activate fast-logging.
45 Affected files lib/silcutil/silclog.[ch]
47 * Changed some code to conform new silclog APIs. Affected
48 files are doc/example_silcd.conf.in, silcd/server.c
49 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
52 * Fixed a memory leak that could occur in some situations.
53 Affected file silcd/serverconfig.c.
55 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
57 * Added the silc_client_del_client to remove the client from
58 all channels as well. Affected file lib/silcclient/idlist.c.
60 * Fixed the client library to correctly remove the client
61 from all channels when the client entry is being destroyed.
62 Affected file lib/silcclient/client_notify.c, command.c.
64 * Added auto-nicking support to the client library. If the
65 applicatio now sets client->nickname it will be sent to the
66 server after connecting by the library. This way for example
67 SILCNICK (or IRCNICK) environment variables will have effect
68 and always change the nickname automatically to whatever
69 it is wanted. Affected file lib/silcclient/client.[ch].
71 * Renamed silc_server_command_bad_chars to the
72 silc_server_name_bad_chars and moved it to the
73 silcd/server_util.[ch]. Added also new function
74 silc_server_name_modify_bad to return nickname that
75 includes bad characters as new nickname without those
76 bad characters. This check and modify is now used in
77 silc_server_new_client when the username is initially set
78 as nickname, so it must be checked to be valid nickname.
79 Affected file silcd/packet_receive.c.
81 * The nickname length is now taken from the packet for real
82 and not trusted to strlen() since it clearly can return
83 wrong length for nickname including bad characters. This
84 also applies to channel names. Affected file silcd/command.c.
86 * Removed the lib/silcsilm/modules directory. Modules are now
87 compiled into the lib/silcsim. Fixed the copying of the
88 modules to follow symbolic links in Makefile.am.pre.
90 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
92 * Fixed silc_string_regexify list creation. Fixes bugs with
93 BAN and INVITE commands in server. The affected file is
94 lib/silcutil/unix/silcunixutil.c.
96 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
98 * Removed the command destructor entirely from the server's
99 command and command reply routines. It is not needed, and
100 its usage was buggy and caused crashes. Affected files are
101 silcd/command[_reply].[ch].
103 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
105 * Cancel protocol and NULL sock->protocol if timeout
106 occurred during protocol. Affected file silcd/server.c.
108 * Cancel protocol timeouts always before calling the final
109 callback, to assure that after final callback is called
110 no other state will be called for the protocol anymore.
111 Affected file silcd/protocol.c.
113 * Print error log if incoming connection configuration could
114 not be found. Affected file silcd/server.c.
116 * Fixed JOIN command to correctly save the founder mode
117 to the client on normal SILC server, when the channel
118 was created by the router. Affected file silcd/command.c.
120 * Fixed LIST command (hopefully) to send correct reply
121 packets. Affected file silcd/command.c.
123 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
125 * The silc_packet_receive_process now returns FALSE if the
126 read data was invalid packet, and TRUE if it was ok.
128 The server now checks that if unauthenticated connection
129 sends data and its processing fails the server will close
130 the connection since it could be a malicious flooder.
132 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
134 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
136 * Make sure the warning about error opening a log file is
137 printed only once and not everytime it fails (produces
138 too much useless log). Affected file lib/silcutil/silclog.c.
140 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
142 * Made the silc_server_daemonise() function more readable.
143 Affected file silcd/server.c.
145 * Pid file is now optional, the user may comment it out from
146 the config file. Removed define SILC_SERVER_PID_FILE, we
147 don't need a default any longer. Affected file
148 configure.in.pre, lib/Makefile.am.pre.
150 * Make some use of the pid file. The server now dies at startup
151 if it detects a valid pid file on his path. The server would
152 die anyway in this circumstance, because of the bind() failure.
153 Affected file silcd/silcd.c.
155 * No longer compiling lib/dotconf.
157 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
159 * Fixed JOIN command parsing not to crash. Affected file
160 lib/silcclient/command.c.
162 * Fied the NICK_CHANGE notify to add the new client entry
163 even it is resolved. This removes an <[unknown]> nick
164 thingy bug in the client. Affected file is
165 lib/silcclient/client_notify.c.
167 * Do not try to allocate 0 bytes (efence does not like it)
168 in lib/silccore/silccomand.c when encoding payload.
170 * Do not take IRCNICK as nickname in Irssi SILC client since
171 it is not possible to set nickname before hand connecting
172 the server (TODO has an entry about adding auto-nicking
175 * Changed the silc_server_command_pending to check whether
176 there already exists an pending entry with the specified
177 command, command identifier and pending callback. This is
178 to fix IDENTIFY and WHOIS related crashes that may register
179 multiple pending commands with same identifier. Affected
180 file silcd/command.c.
182 * Fixed the server to reconnect to the router even if it
183 was already reconnecting and EOF was received. This to
184 fix a possibility that the server wouldn't ever try to
185 auto-reconnect to the router. Affected file silcd/server.c.
187 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
189 * Fixed the server's password authentication to use the
190 length of the locally saved password, and not the one
191 sent in the packet. Affected file silcd/protocol.c.
193 * Fixed same password authentication problem in the
194 Authentication Payload handling routines in
195 lib/silccore/silcauth.c.
197 * Yet another password authentication problem fixed with
198 channel password handling in silcd/command.c.
200 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
202 * If first character of string in silc_parse_userfqdn is '@'
203 then do not parse it. Affected file is
204 lib/silcutil/silcutil.c.
206 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
208 * Fixed minor bug in IDENTIFY command reply sending, which
209 caused various weird problems during JOIN when it was
210 resolving names for users. Affected file silcd/command.c.
212 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
214 * Fixed the IDENTIFY command reply sending to chech better valid
215 clients. It was possible to send incomplete list of replies.
216 Affected file silcd/command.c.
218 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
220 * Added silc_client_command[s]_[un]register functions now to
221 dynamically register the commands in client library. Removed
222 the static table of commands. This allows the client library
223 to call commands without causing the application to know about
224 what commands library has called.
226 Removed the INFO command reply kludge to detect when the command
227 was called by library. Now library use its own command reply
228 function for INFO command.
230 Added function silc_client_command_call to call a command.
231 Application can use it to call command, not access the structure
234 Now all commands that are sent by the client library (not
235 explicitly sent by application) use own command reply functions.
237 Affected files around lib/silcclient/ and in
238 irssi/src/silc/core/.
240 * Fixed the WHOIS command reply sending to chech better valid
241 clients. It was possible to send incomplete list of replies.
243 Fixed the WHOIS and IDENTIFY to send the request to router
244 if normal server did not do it and did not find any results.
246 Affected file silcd/command.c.
248 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
250 * Moved the internal data from SilcClient context into its
251 own file, not accesible to application. Affected files
252 lib/silcclient/client.h and lib/silcclient/client_internal.h,
253 and other files in client library.
255 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
257 * Added doc/examples installation target in Makefile.am.pre.
260 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
262 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
263 commands the found client entry will be removed from the
264 cache, after notifying application about the error. Affected
265 file lib/silcclient/command_reply.c.
267 * Changed the /MSG to check for exact nickname user gave, and
268 not let `nick' match `nick@host' if it is only one found. Now,
269 user must type the exact nickname (like nick@host2) even if
270 there are no more than one same nicks found. This is to avoid
271 a possibility of sending nickname to wrong nickname since
272 `nick' could match `nick@host'. Affected file is
273 irssi/src/core/silc-servers.c.
275 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
277 * Do not print "you are now server operator" or similar when
278 giving /away command. Affected files are
279 irssi/src/silc/core/client_ops.c, silc-servers.h.
281 * Made the silc_server_command_pending_error_check to send
282 the same command reply payload it received back to the
283 original sender of the command. This way all arguments
284 that was received by the server will be received by the
285 client too. Affected file silcd/command.c.
287 * Added the silc_idcache_add to return the created cache entry
288 to a pointer. Affected file lib/silccore/silcidcache.[ch].
290 * Add global clients to expire if they are not on any channel.
291 This is because normal server will never know if they signoff
292 if they are not on any channel. The cache expiry will take
293 case of these entries. This is done by normal servers only.
294 The affected files are silcd/command_reply.c,
295 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
297 * If server receives invalid ID notification for WHOIS or
298 IDENTIFY and the ID exists in the lists, it is removed.
299 Affected file silcd/command_reply.c.
301 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
302 in client then client entry that it matches is searched and
303 the nickname is printed on the screen for user. Affected
304 file irssi/src/silc/core/client_ops.c.
306 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
308 * Use cache entry expire time in the LIST command reply to
309 purge old entries from the cache after the LIST command
310 reply has been received. This way we don't have non-existent
311 entries in the cache for too long. Affected file is
312 silcd/command_reply.c.
314 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
316 * If we are normal server, and we've not resolved client info
317 in WHOIS or IDENTIFY from router, and it is global client,
318 we'll check whether it is on some channel. If it is not
319 then we cannot be sure about its validity and will resolve it
320 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
321 file silcd/command.c.
323 * Search channel by name (if possible) rather than by ID
324 in IDENTIFY command's command reply. Affected file is
325 silcd/command_reply.c.
327 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
329 * Distribute to the channel passphrase in CMODE_CHANGE notify.
330 Updated specs and implemented it. Affected file silcd/command.c,
331 silcd/packet_send.c and silcd/packet_receive.c.
333 * Implemented the <founder auth> payload handling in the JOIN
334 command. If provided all conditions for channel joining
335 except requirement to provide correct passphrase can be
336 overrided by the channel founder. Updated the protocol specs.
337 Affected file silcd/command.c.
339 Added support for founder auth in JOIN command in client
340 library. Fixed the parsing of the JOIN command now to support
341 all options as they should be. The affected file is
342 lib/silcclient/command.c.
344 * Optimized the WHOIS and IDENTIFY commands to send the request
345 to router only if it includes nicknames or other names. If
346 they include only IDs then check the local cache first before
347 routing. Affected file is silcd/command.c.
349 * Added channels topic announcements. Affected file is
350 silcd/packet_receive.c and silcd/server.c.
352 * Fixed the silc_server_send_notify_topic_set to really destine
353 the packet to channel. Affected file silcd/packet_send.c.
355 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
356 library. Affected file lib/silcclient/client_notify.c.
358 * Added UMODE announcements. Affected file silcd/server.c.
360 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
362 * Memory leak fixes in:
364 lib/silcutil/silcsockconn.c
365 lib/silcske/silcske.c
368 lib/silccrypt/silcpkcs.c
369 lib/silccore/silccommand.c
370 lib/silccore/silcidcache.c
375 * ROBOdoc documented the lib/silcske/groups.h file and a
376 bit changed the interface for better.
378 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
380 * Update the client entry context in the ID cache after
381 nick change. Affected file lib/silcclient/command.c.
382 Fixes the CUMODE command when regaining founder privileges,
383 and a little WHOIS problem.
385 * Fixed silc_net_gethostbyname to correctly call the
386 inet_ntop. Affected file lib/silcutil/silcnet.c.
388 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
390 * Added IPv6 support checking to the configure.in.pre, added
391 also --enable-ipv6 option to override the check. Affected
392 file configure.in.pre.
394 * The silc_thread_create now calls the start function
395 directly if threads support is not compiled in. Removes
396 ugly #ifdef's from generic code. Affected files are
397 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
399 * Added silc_net_gethostby[name/addr]_async to asynchronously
400 resolve. Affected files are lib/silcutil/silcnet.[ch].
402 * Added support for rendering IPv6 based server, client and
403 channel IDs. Affected file lib/silcutil/silcutil.c.
405 * Added support for creating IPv6 based server IDs. Affected
406 file is silcd/serverid.c.
408 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
410 * Added silc_net_gethostby[addr/name] into the
411 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
412 routines. Added silc_net_is_ip[4/6]. Affected file is
413 lib/silcutil/unix/silcunixnet.c. All routines that take
414 address as argument now supports both IPv4 and IPv6 addresses.
416 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
418 * Fixed LIST command reply sending in server. Affected file
421 * Server now sends the kicker's client ID in the KICK notify
422 to the kicked client. Affected file silcd/command.c.
424 * The client library now parses the kickers client ID and
425 UI displays it. Affected files lib/silcclient/client_notify.c
426 and irssi/src/silc/core/silc-channels.c, module-formats.c.
428 * Made all payload parsing function prototypes consistent.
429 They all take now const unsigned char * and uint32 pair as
430 the payload data instead of SilcBuffer. Changes all around
431 the source tree. Other unsigned char* -> const unsigned char*
432 changes around the tree as well.
434 * Optimized SFTP client and server packet sending not to
435 allocate new buffer for each packet but to recycle the
436 first allocated buffer. Affected files are
437 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
439 * Optimized the SFTP client to use SilcList instead of
440 SilcDList for requests, because it is faster. Affected file
441 is lib/silcsftp/sftp_client.c.
443 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
444 into lib/silccore/silcid.[ch].
446 Renamed silcpayload.[ch] into silcargument.[ch].
448 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
450 * If client entry is deleted with active key agreement
451 session, abort the session.
453 The silc_client_abort_key_agreement now calls the completion
454 callback with new SILC_KEY_AGREEMENT_ABORTED status.
456 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
459 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
461 * Don't use __restrict in older GCC's. Affected file is
462 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
464 * silc_net_localhost now attempts to reverse lookup the
465 IP/hostname. Affected file lib/silcutil/silcnet.c.
467 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
468 command. It can be used to gain founder privileges at
469 the same time when joining the channel.
471 Defined that the SILC_NOTIFY_TYPE_KICKED send the
472 kicker's client ID as well. Updated protocol specs.
474 Defined that the server must send SILC_COMMAND_IDENTIFY
475 command reply with error status to client who sent
476 private message with invalid client ID.
478 Updated the protocol specification.
480 * Added silc_server_send_command_reply to send any
481 command reply. Affected file silcd/packet_send.[ch].
483 * Added silc_id_payload_encode_data to encode ID payload
484 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
486 * The server now send IDENTIFY command reply with error
487 status if client ID in private message is invalid. Affected
488 file silcd/packet_receive.c.
490 * Save the server key file with server's IP address in
491 the filename instead of hostname. The affected file is
492 irssi/src/silc/core/client_ops.c.
494 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
496 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
499 * Added libtool support for compiling shared objects in
500 lib/silcsim. Affected file configure.in.pre and
501 lib/silcsim/Makefile.am. Original patch by cras.
503 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
505 * Pid file configuration, and server's config file fixes
506 patch by toma. Updated CREDITS file.
508 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
510 * Fixed silc_client_channel_message to not try to decrypt
511 the message twice if it resolved the destination client
512 information. This could cause of dropping one channel
513 message. Affected file lib/silcclient/client_channel.c.
515 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
517 * Added silc_client_run_one into lib/silcclient/silcapi.h and
518 lib/silcclient/client.c. This function is used when the SILC
519 Client is run under some other scheduler, or event loop or
520 main loop. On GUI applications, for example this may be
521 desired to used to run the client under the GUI application's
522 main loop. Typically the GUI application would register an
523 idle task that calls this function multiple times in a second
524 to quickly process the SILC specific data.
526 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
528 * Fixed silc_server_drop() for dropping the supplementary
529 groups as well, this could cause a security hole on some
532 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
534 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
537 * Write PID file after dropping privileges. Added -F option
538 to run server on foreground. A patch by debolaz.
539 Affected files silcd/server.c, silcd/silcd.c.
541 * Fixed MOTD to return the MOTD file server name. Affected
542 file silcd/command.c.
544 * Added INFO command reply handling to the Irssi SILC Client.
545 Affected file irssi/src/silc/core/client_ops.c.
547 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Fixed the silc_idcache_list_* routines to really support
550 the dynamic list. Fixes a crash. Affected file is
551 lib/silccore/silcidcache.c.
553 * Fixed the LIST command reply to really call LIST command's
554 pending callbacks. Affected file silcd/command_reply.c.
556 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
558 * Update conn->local_entry->nickname after giving NICK
559 command. Affected file lib/silcclient/command.c.
561 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
563 * Added the [pid] option to the silcd configuration file
565 Affected files: serverconfig.[ch] and silcd.c
567 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
569 * Save fingerprint in WHOIS command reply in server.
570 Affected file silcd/command_reply.c.
572 * Fixed NICK commands pending callback registration.
573 Affected file lib/silcclient/command.c.
575 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
577 * Use ++server->cmd_ident when sending commands in server,
578 instead of random number. Affected file silcd/command.c.
580 * Fixed GETKEY command reply to call actually GETKEY pending
581 command callbacks. Affected file silcd/command_reply.c.
583 * A bit stricter check for nicknames. Check for same nickname
584 in NICK command also. Affected file silcd/command.c.
586 * Do not call INFO command everytime client ID changes, only
587 during first connecting. Affected file lib/silcclient/client.c.
589 * Set the new nickname only after successful command reply for
590 NICK command is returned by server. Affected file
591 lib/silcclient/command.c.
593 * Remove nicknames from nicklist during server_signoff notify.
594 Should fix /NAMES bit more. The affected file is
595 irssi/src/silc/core/silc-channels.c.
597 * Added `fingerprint' field to the SilcIDListData in the
598 silcd/idlist.h to hold the fingerprint of the client's
601 Send the fingerprint of the client's public key in WHOIS
604 Affected files silcd/command.c, and silcd/idlist.[ch].
606 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
607 create fingerprint from given data.
609 * Show the fingerprint of the client's public key in WHOIS.
610 Affected files irssi/src/module-formats.[ch] and
611 irssi/src/silc/core/client_ops.c.
613 * Format the multiple same nicknames also during JOIN and
614 NICK_CHANGE notifys. Affected file is
615 lib/silcclient/client_notify.c.
617 * Do not print error on screen for invalid private message
618 payload since it can come if someone is sending private
619 messages with wrong key. Affected file
620 lib/silccore/silcprivate.c.
622 * Fixed multiple concurrent /PING crash. Affected file
623 lib/silcclient/command.c.
625 * Changed the wrong ID encoding. All IP addresses must be
626 in MSB first order in encoded format. They were encoded
627 wrong and was in LSB format. Affected files are
628 silcd/serverid.c, lib/silcutil/silcutil.c.
630 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
632 * Call the `connect' client operation through the scheduler
633 in case of error. Affected file lib/silcclient/client.c.
635 * Call the `failure' client operation even if the error
636 occurred locally during a protocol. Affected file is
637 lib/silcclient/protocol.c.
639 * Added support of sending LIST command to router from normal
640 server. This way normal server can get list of all channels
641 in the network too. Fixed the channel list sending in the
642 server too. Affected files are silcd/command.c, and
643 silcd/command_reply.[ch].
645 * Added silc_server_update_channels_by_server and
646 silc_server_remove_channels_by_server. They are used during
647 disconnection of primary router and in backup router protocol.
648 Affected file silcd/server_util.[ch], silcd/server.c and
649 silcd/server_backup.c.
651 * Fixed channel adding to global list in IDENTIFY command
652 reply in server. Affected file silcd/command_reply.c.
654 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
656 * If the incoming packet type is REKEY or REKEY_DONE process
657 that packet always synchronously. Fixes yet another MAC
658 failed error on slow (dialup) connections. Affected file
659 lib/silcclient/client.c and silcd/server.c.
661 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
663 * Call check_version SKE callback for initiator too. Affected
664 file lib/silcske/silcske.c.
666 * Implemented fix for security hole found in the SKE that was
667 fixed in the specification few days back; the initiator's
668 public key is now added to the HASH value computation.
669 Added backwards support for the old way of doing it too, for
670 old clients and old servers. Affected file is
671 lib/silcske/silcske.c.
673 * Enabled mutual authentication by default in SKE. If initiator
674 is not providing mutual authentication the responder will
675 force it. This will provide the proof of posession of the
676 private key for responder. The affected files are
677 lib/silcclient/protocol.c and silcd/protocol.c.
679 * Do not cache anymore the server's public key during SKE.
680 We do mutual authentication so the proof of posession of
681 private key is done, and if the server is authenticated in
682 conn auth protocol with public key we must have the public
683 key already. Affected file silcd/protocol.c.
685 * Added new global debug variable: silc_debug_hexdump. If
686 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
687 file lib/silcutil/silclog.[ch].
689 * Fixed compilation warning due to char * -> const char *.
690 Affected files lib/silcutil/silcnet.h, and
691 lib/silccore/silcauth.[ch].
693 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
695 * Fixed CMODE command when new channel key was created. If
696 the creation failed the old key was removed. Next time giving
697 same command would crash the server since the old key was
698 freed already. Affected file silcd/command.c.
700 * Fixed the silc_server_announce_get_channels to not crash
701 on reconnect. Affected file silcd/server.c.
703 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
705 * Added silc_log_set_debug_string function to set a regex
706 string to match for debug output. Only the function names,
707 or filenames matching the given debug string is actually
708 printed. This way it is possible to filter out those debug
709 strings that user is not interested in.
711 Fixed a bug in silc_string_regexify.
713 Affected files lib/silcutil/silclog.[ch], and
714 lib/silcutil/unix/silcunixutil.c.
716 * Changed the -d options in both server and Irssi SILC client
717 to take the debug string as argument. Affected files
718 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
720 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
722 * Added silc_hash_babbleprint to create a Bubble Babble
723 Encoded fingerprint. The encoding is developed by Antti
724 Huima (draft-huima-babble-01.txt), and it creates human
725 readable strings out of binary data. Affected file
726 lib/silccrypt/silchash.[ch].
728 * Print the babble print now in addition of fingerprint as well
729 in Irssi SILC client. Affected files are
730 irssi/src/fe-common/silc/module-formats.[ch],
731 irssi/src/fe-common/silc/core/client_ops.c.
733 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
735 * Fixed a security problem found in SKE. The initiator's
736 public key too is now added to the HASH hash value creation
737 which is signed by the responder to create the SIGN value.
738 This will prevent anyone in the middle to lie to the responder
739 about the initiator's public key. If this is done now, the
740 man in the middle will get caught. Updated the protocol
743 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
745 * Better installation directory handling. Configure module
746 paths and other paths automatically to example_silc* files
747 in doc/. A patch by toma.
749 * Fixed compiler warning from MPI library, and from SILC RNG.
752 * Added SILC_SERVER_PID_FILE to define the pid file for server.
753 It can be configured with ./configure. A patch by toma.
755 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
757 * Find correct make to use in prepare-clean. A patch by
758 toma. Affected file prepare-clean.
760 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
762 * Added irssi variables use_auto_addr, auto_bind_ip,
763 auto_bind_port and auto_public_ip.
765 * Changed the interface for silc_client_send_key_agreement
766 in lib/silcclient/silcapi.h
770 irssi/src/silc/core/silc-core.c
772 lib/silcclient/silcapi.h
773 irssi/src/silc/core/silc-channels.c
774 lib/silcclient/client_keyagr.c
777 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
779 * Added silc_pkcs_public_key_compare to compare two
780 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
782 * Check that the client who set the founder mode on the
783 channel is the same client that is giving the founder
784 mode to itself. It is done by comparing the saved public
785 key (it is saved even in the authentication is passphrase).
786 Affected file silcd/command.c.
788 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
790 * Do not process packet for disconnected socket connection.
791 Affected file lib/silccore/silcpacket.c.
793 * Process the DISCONNECT packet through scheduler in the
794 client library. Affected file lib/silcclient/client.c.
796 * Fixed the silc_client_packet_parse to not to increase
797 the packet sequence number if the conn->sock and the
798 current socket connection is not same. This can happen
799 for example during key agreement when the conn includes
800 multiple socket connections (listeners). Affected file
801 lib/silcclient/client.c.
803 * The sender of the file transfer request now provides also
804 the pointer (listener) for the key exchange protocol. If
805 the listener cannot be created then it sends empty key
806 agreement and lets the receiver provide the listener.
808 Added `local_ip' and `local_port' arguments to the
809 silc_client_file_send. If they are provided they are used,
810 if not then it will attempt to find local IP address, if
811 not found or bind fails then the remote client will provide
814 Affected files are lib/silcclient/client_ftp.c and
815 lib/silcclient/silcapi.h.
817 * Extended the FILE SEND command to support defining the
818 local IP and port for key exchange listener. They are
819 optional. Affected file irssi/src/silc/core/silc-servers.c.
821 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
823 * Defined to WHOIS command reply the sending of fingerprint
824 of the client's public key (if the proof of posession of the
825 corresponding private key is verified by the server).
826 Updated to the protocol specification.
828 * Added support of receiving the client's public key's
829 fingerprint in command reply in client library. Affected
830 file is lib/silcclient/command_reply.c, and
831 lib/silcclient/idlist.[ch].
833 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
835 * Do not send over 128 chars long nickname to the server
836 in NICK command. Affected file lib/silcclient/command.c.
838 * Do not send over 256 chars long channel names to the server
839 in JOIN command. Affected file lib/silcclient/command.c.
841 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
843 * Assure that silc_server_close_connection cannot be called
844 twice for same socket context. Affected file is
847 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
849 * Send error message to application if opening file for
850 writing during file transfer fails. Affected file is
851 lib/silcclient/client_ftp.c.
853 Remove all file transfer sessions for a client that we're
854 removing from ID cache.
856 Affected file is lib/silcclient/client_ftp.c.
858 * Fixed silc_net_addr2bin to return correct address. Affected
859 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
861 * Fixed file transfer session removing on signoff notify.
862 Affected file irssi/src/silc/core/silc-servers.c.
864 * Added the SilcClientFileError to be returned in the monitor
865 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
866 Affected file lib/silcclient/silcapi.h.
868 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
870 * Fixed a crash in silc_client_ftp_free_sessions and
871 silc_client_ftp_session_free_client. Affected file
872 lib/silcclient/client_ftp.c.
874 * Added `disabled' field in the SilcChannelEntry in the server
875 to indicate if the server entry is disabled. Affected file
876 silcd/idlist.h, silcd/command[_reply].c.
878 * SILC server adds now /var/run/silcd.pid everytime it is
879 started. Affected file silcd/silcd.c.
881 * Added silc_server_packet_send_clients to send a packet to
882 the provided table of client entries. Affected file
883 silcd/packet_send.[ch].
885 * Fixed a crash in client resolving in client_prvmsg.c in
886 client library. Affected file lib/silcclient/client_prvmsg.c.
888 * Do not actually remove the client directly from ID cache
889 during SERVER_SIGNOFF, but invalidate it. This way we
890 preserve the WHOWAS info for the client. Affected file
893 * Fixed SERVER_SIGNOFF notify handling in the server. The
894 server is now able to process incoming SERVER_SIGNOFF notify
895 for a server that it doesn't even know about. It will remove
896 the clients provided in the notify. Affected file
897 silcd/packet_receive.c.
899 * Check for partial packet in data queue after every packet that
900 was found from the queue. Return and wait for more data if
901 there is partial data in queue. Affected file is
902 lib/silccore/silcpacket.c.
904 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
906 * Added SilcClietFileError enum to indicate error in
907 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
908 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
909 Affected files lib/silcclient/silcapi.h and

912 * Check that newsize in silc_buffer_realloc is larger than
913 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
915 * Added better monitor of file transfers. It now monitors
916 key agreement protocol during the file transfer too. Added
917 error reporting too. Affected files
918 irssi/src/silc/core/silc-servers.c,
919 irssi/src/fe-common/silc/module-formats.[ch].
921 * Wrote a help file for FILE command.
923 * Added silc_rng_global_get_byte_fast to get not-so-secure
924 random data as fast as possible. Random data is read from
925 /dev/urandom if available and from the SILC RNG if not
926 available. It is used in padding generation. Affected file
927 lib/silccrypt/silcrng.[ch].
929 * All packets in client library are now processed synchronously.
930 Optimized packet processing a lot. Affected file
931 lib/silcclient/client.c.
933 * All server connection packets are processing synchronously
934 now in server, to optimize packet processing. Affected file
937 * Include files are installed now only in Toolkit distribution
938 if make install is given. Affected files: all Makefile.am's.
940 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
942 * Assure that silc_client_notify_by_server_resolve does not
943 resolve the client information multiple times. If it cannot
944 be found by the first it cannot be found at all. Affected
945 file lib/silcclient/client_notify.c.
947 * Fixed WHOWAS command reply calling. Affected file
948 lib/silcclient/command_reply.c.
950 * Removed all references to silc_idlist_get_client from the
951 Irssi SILC client since that call is internal call used by
952 the library. The Irssi SILC client will use now client
953 retrieval functions found in silcapi.h.
955 * Fixed a bug in resolving nickname info before sending
956 private message. It used freed memory. Affected file
957 irssi/src/silc/core/silc-servers.c.
959 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Assure my_channels statistics cannot go negative in server.
962 Affected files silcd/server.c, silcd/server_util.c.
964 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

974 lib/sftp/sftp_fs_memory.c.
976 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
978 * Added silc_net_localip to return local host's IP address.
979 Affected file lib/silcutil/silcnet.[ch].
981 * If key exchange or rekey protocol is active for a connection
982 parse all packets syncronously since there might be packets
983 in packet queue that we are not able to process without first
984 processing packets before them. Affected file silcd/server,
985 lib/silcclient/client.c.
987 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
988 whether library should continue processing the packet.
989 Affected file lib/silccore/silcpacket.h.
991 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
992 SilcSFTPMonitorData to SFTP server to monitor various

1020 lib/silcutil/silcutil.[ch].
1022 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Resolve the client info when received private message or
1025 channel message for a client which nickname we don't know.
1026 Affected files lib/silcclient/client_prvmsg.c and
1027 lib/silcclient/client_channel.c.
1029 * Do not crash in /KEY if client is not connected. Affected
1030 file irssi/src/silc/core/silc-channels.c.
1032 * Added SilcClientStatus field to the SilcClientEntry in the
1033 lib/silcclient/idlist.h.
1035 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1036 is incomplete and is being resolved, it won't be resolved
1039 Make sure also that USERS command reply does not resolve
1040 twice information. Affected file is
1041 lib/silcclient/command_reply.c.
1043 Make sure that silc_client_get_clients_by_list does not
1044 resolve twice same information.
1046 * Check for valid client->id in the silc_server_free_client_data.
1047 Affected file silcd/server.c.
1049 * Fixed /GETKEY nick@server not to crash if the server entry
1050 is not found. Affected file lib/silcclient/command.c.
1052 * Fixed the silc_server_check_cmode_rights to check the
1053 requested modes correctly. Affected file silcd/command.c.
1055 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1057 * Better checks for non-printable chars in nick added.
1058 Affected file silcd/command.c.
1060 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Call the silc_server_udpate_servers_by_server in the
1063 primary router that comes back online in the backup resuming
1064 protocol. Otherwise it routes packets wrong. Affected file
1065 silcd/server_util.[ch], silcd/server_backup.c.
1067 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1069 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1070 lib/silcutil/silcbuffmt.[ch].
1072 * Redefined the SILC packet header to include the padding
1073 length. Affected file lib/silccore/silcpacket.[ch].
1075 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1076 length for maximum padding up to 128 bytes). Affected
1077 file lib/silccore/silcpacket.h.
1079 * Removed all backwards support for old 0.5.x MAC thingies.
1080 The SILC packet header change makes it impossible to be
1081 backwards compatible.
1083 * Send the ENDING packet with timeout in the backup resuming
1084 protocol. This is to assure that all routers has connected
1085 to the primary router. Affected file silcd/server_backup.c.
1087 * Changed the RNG to take the first IV from random data. It
1088 used to take it from zero actually. Changed the RNG also
1089 to use /dev/urandom during session. /dev/random is used
1090 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1092 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1094 * Changed the SILC packet header to have the first two bytes
1095 (the packet length) encrypted. Affected files aroung the
1096 code tree, lib/silccore/silcpacket.[ch]. Removed the
1097 SilcPacketCheckDecrypt callback. It is not needed anymore
1098 since the silc_packet_receive_process will determine now
1099 whether the packet is normal or special.
1101 * Implemented the unidirectional MAC keys. Affected files
1102 lib/silcske/silcske.c, silcd/protocol.c and
1103 lib/silcclient/protocol.c.
1105 * Implemented the packet sequence number to the MAC computation.

1108 lib/silcclient/protocol.c.
1110 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Allow backup router to announce servers. All servers
1113 announced by backup router are added to the global list
1114 automatically. Update hte server's socket to our primary
1115 router also when backup router announces a server.
1116 Affected file silcd/packet_receive.c.
1118 * Do not update the client->router in the function
1119 silc_server_udpate_clients_by_server if the client is on
1120 global list. We might fail to find any specific server
1121 for locally connected clients and local cell clients. They
1122 should still use the `from' and not `to' as client->router.
1123 This fixes backup router resuming protocol. Affected file
1124 silcd/server_util.c.
1126 * Decrease channel statistics count only if the channel
1127 deletion worked. Affected files are silcd/server.c and
1128 silcd/server_util.c.
1130 * Added silc_server_update_servers_by_server to update origin
1131 of all server entries. Used during backup router protocol.
1132 Affected files silcd/server_util.[ch], silcd/server.c. and
1133 silcd/backup_router.c.
1135 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1136 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1137 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1138 lib/silccrypt/silchmac.c.
1140 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Assure that router cannot reroute the same channel message
1143 to the sender. Affected file silcd/packet_receive.c.
1145 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1147 * Made better checks that the channel message is not sent
1148 to the router it came from. Affected file is
1149 silcd/packet_send.c. Fixed memory leak too.
1151 * Announce informations for incoming router connection, but
1152 only after checking if it is replaced by backup router.
1153 Affected file silcd/packet_receive.c.
1155 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * Fixed the backup resuming protocol to work in multiple
1158 router environment. Affected file silcd/server_backup.c.
1160 * Route packet only to one router in the function
1161 silc_server_packet_send_to_channel. Affected file is
1162 silcd/packet_send.c.
1164 * Fixed silc_server_send_notify_dest to set the broadcast
1165 flag. Fixed the silc_server_send_notify_topic to actually
1166 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1167 Affected file silcd/packet_send.c.
1169 * Changed the SFTP Filesystem interface. Changed the
1170 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1171 the filesystem operation function. The SilcSFTPFilesystem
1172 is now a context that is allocated by all filesystem allocation
1173 functions and it already includes the operations structure
1174 and filesystem specific context. It is given as argument
1175 now to the silc_sftp_server_start. This made the interface
1176 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1177 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1179 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1181 * Changed the backup router adding and getting interfaces
1182 in the server. The router that will be replaced by the
1183 specified backup router is now sent as argument. Affected
1184 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1187 * Added silc_net_addr2bin_ne to return the binary form of
1188 the IP address in network byte order. Affected files
1189 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1191 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1193 * Check for existing server ID in silc_server_new_server
1194 and in silc_server_connect_to_router_final and remove the
1195 old entry if it exists. Affected file silcd/packet_receive.c,
1198 * Send the channel message always to only one router, either
1199 in upstream or downstream. Affected file is
1200 silcd/packet_send.c.
1202 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * Wrote the definition of the backup resuming protocol to the
1205 protocol specification.
1207 * Removed one redundant channel key generation from normal
1208 server during joining procedure. Removed one redundant
1209 channel key sending from server to router during joining
1210 procedure. Affected file silcd/command.c.
1212 * Made minor bugfixes to the backup router resuming protocol.
1213 Affected file silcd/server_backup.c, server.c.
1215 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Added --disable-asm configuration option. Affected files
1218 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1221 * Implemented the backup resuming protocol that is used to
1222 resume the primary router position in the cell after the
1223 primary router comes back online. Affected files
1224 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1225 and silcd/server_util.[ch].
1227 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1229 * Sleep two (2) seconds after sending QUIT command to server.
1230 Affected file lib/silcclient/command.c.
1232 * Assure that if outgoing data buffer is pending do not force
1233 send any data. Affected file silcd/packet_send.c.
1235 * Assure that if outgoing data buffer is pending do not force
1236 send any data. Affected file lib/silcclient/client.c.
1238 * Implemented the backup router support when the primary router
1239 goes down. The servers and routers can now use the backup
1240 router as new primary router without loosing connectivity.
1242 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1244 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1245 in the server to indicate disabled entry. All data read
1246 from the connection will be ignored and no data is sent
1247 for entry that is disabled. Affected files are
1248 silcd/idlist.h, silcd/server.c.
1250 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Created SFTP client and server test programs in the
1253 lib/silcsftp/tests directory.
1255 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Implemented memory filesystem (virtual filesystem) for
1258 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1261 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Implemented the SFTP (SSH File Transfer Protocol) to the
1264 lib/silcsftp. It includes SFTP client and SFTP server
1267 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1269 * Moved lib/silccore/silcprotocol.[ch] to the
1270 lib/silcutil library.
1272 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1273 take variable argument list pointer as argument. Affected
1274 file lib/silcutil/silcbuffmt.[ch].
1276 * Added silc_buffer_set function that is used to set data
1277 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1278 Affected file lib/silcutil/silcbuffer.h.
1280 * Changed various routines in the core library to use the new
1281 silc_buffer_set instead of allocating new buffer only for
1284 * Added 64-bit value formatting and unformatting support to the
1285 silc_buffer_[un]format routines. Affected file is
1286 lib/silcutil/silcbuffmt.[ch].
1288 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1289 to includes/bitmove.h.
1291 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * Fixed channel user mode saving in client library. Affected
1294 file lib/silcclient/command[_reply].c.
1296 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1298 * Defined the file transfer to the SILC Protocol. Added
1299 new packet type SILC_PACKET_FTP and defined File Transfer
1300 Payload. The mandatory file transfer protocol is SFTP
1301 (SSH File Transfer Protocol). Affected file in addition
1302 of the internet draft is lib/silccore/silcpacket.h.
1304 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1305 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1306 is used as part of backup router protocol when the primary
1307 router of the cell is back online and wishes to resume
1308 the position as primary router.
1310 * Redefined the MAC generation keys in the protocol. The
1311 same key is not used anymore in both direction. Both
1312 direction will now use different keys for sending and
1313 receiving. This fixes a potential security flaw. This
1314 change causes incompatibilities in the protocol.
1316 * Redefined also the MAC computation from the packet.
1317 An packet sequence number is now added to the MAC
1318 computation. This prevents possible replay attacks against
1319 the protocol. This change too causes incompatibilities
1322 Added `sequence' field to the SilcPacketContext to hold
1323 the current sequence number for the packet.
1325 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Added `created' field to the SilcIDListData in the file
1328 silcd/idlist.h to indicate the time when the entry was
1331 * Added `created' field to the SilcChannelEntry too. Affected
1332 file silcd/idlist.h.
1334 * Added `creation_time' aguments to all the announcement functions
1335 in the server. If it is provided then only the entries that
1336 was created after the provided time frame are actually
1337 announced. Affected file silcd/server.[ch].
1339 * The protocol says that the Channel ID's IP address must be
1340 based on the router's IP address. Added check for this in
1341 the silc_server_new_channel when processing incoming New Channel
1342 Payload. Affected file silcd/packet_receive.c.
1344 * Print out the correct version with --version in SILC client.
1345 Affected file irssi/src/silc/core/silc-core.c.
1347 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1349 * Fixed WHOWAS command to check for completnes of the client
1350 entry always, not just when the command is coming from client.
1351 Affected file silcd/command.c.
1353 * Added new function silc_server_packet_queue_purge to purge the
1354 outgoing data queue to the network. After the function returns
1355 it is guaranteed that the outgoing packet queue is empty.
1356 Affected file silcd/packet_send.[ch].
1358 * Purge the outgoing packet queue in the rekey protocol's final
1359 callback to assure that all rekey packets go to the network
1360 before quitting the protocol. Affected file silcd/server.c.
1362 * Added silc_client_packet_queue_parse as similar function as
1363 in server to the client library. The affected file is
1364 lib/silcclient/client.c.
1366 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * Splitted silcd/server.c and created silcd/server_util.[ch]
1369 for utility functions.
1371 * Added new socket flag SILC_SF_DISABLED to indicate that the
1372 connection is open but nothing can be sent to or received from
1373 the connection. Affected file lib/silcutil/silsockconn.[ch].
1374 The checking for disabled socket is checked in the low level
1375 silc_socket_write and silc_socket_read functions.
1377 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1379 * Allow only nicknames and channel names that fits into the
1380 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1382 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1384 * When processing JOIN command reply in server check that if
1385 the channel exists in our global list we'll move it the local
1386 list. Affected file silcd/command_reply.c.
1388 * Fixed the check whether client is joined on the channel already
1389 in JOIN command. Affected file lib/silcclient/command.c.
1391 * Fixed the JOIN command reply to check whether the channel
1392 already exists. Affected file lib/silcclient/command_reply.c.
1394 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Added silc_ske_status_string to map the SKE error numbers
1397 to readable strings. The affected files are
1398 lib/silcske/silcske[_status].[ch].
1400 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1402 * Do not show the private channels on the WHOIS channel list
1403 as it is not allowed by the protocol. The affected file is
1406 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1408 * Assure that the packet length digged from the actual packet
1409 is something sensible in the silc_packet_decrypt_rest_special
1410 in lib/silccrypt/silcpacket.c.
1412 * Free and NULL the allocated pointer in silc_hmac_alloc if
1413 the HMAC allocation fails. The affected file is
1414 lib/silccrypt/silchmac.c.
1416 * Print the selected security properties to the log files in
1417 the server. Affected file silcd/protocol.c.
1419 * Add SKE's reference counter even if calling the completion
1420 callback manually. Otherwise it goes negative, although it
1421 does not cause any problems. The affected file is
1422 lib/silcske/silcske.c.
1424 * Remove the client entry with short timeout after giving the
1425 KILL command. Affected file lib/silcclient/command.c.
1427 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1428 case all found clients are already disconnected (WHOWAS would
1429 found them) in the server. Affected file silcd/command.c.
1431 * Update the last_receive (time of last data received) to be
1432 updated only when received private or channel message so that
1433 the idle time showed in WHOIS makes more sense.
1435 * Added boolean field `valid' in to the SilcClientEntry in the
1436 client library to indicate whether the entry is valid or not.
1437 This fixes the nickname change bug on channel when changing
1438 the nickname to be same than the old (like nick to Nick) the
1439 nickname formatter doesn't set the new nick anymore to Nick@host.
1440 Affected file lib/silcclient/idlist.[ch].
1442 * Now actually fixed the nickname changing on disconnection.
1443 Added new function silc_change_nick to the Irssi SILC Client.
1444 Affected file irssi/src/silc/core/client_ops.c,
1445 irssi/src/silc/core/silc-nicklist.[ch].
1447 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1449 * Check that the public key exists in the GETKEY command before
1450 trying to encode it. Affected file silcd/command.c.
1452 * Print some notifications on received public keys with GETKEY
1453 command in the Irssi SILC Client. Affected files are
1454 irssi/src/fe-common/silc/module-formats.[ch],
1455 irssi/src/silc/core/client_ops.c.
1457 * Use IDENTIFY command to resolve the server information in the
1458 GETKEY command instead of INFO command. Affected file
1459 lib/silcclient/command.c.
1461 * All command reply functions in the client library now calls
1462 the pending command reply callbacks even if an error has
1463 occurred. The server has done this a long time and now it was
1464 time to move the client library to this as well. Now all
1465 errors can be delivered back to the pending command reply
1466 callbacks if necessary. Affected files are
1467 lib/silcclient/command[_reply].[ch].
1469 * Change the nickname on disconnection back to the username
1470 because in reconnect the server will enforce it to it anyway.
1471 Affected file irssi/src/silc/core/silc-servers.c.
1473 * Fixed a config file parsing bug in the Irssi SILC client.
1474 Affected file irssi/src/silc/core/clientconfig.c.
1476 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * When printing the channel mode on JOIN, verify that the
1479 channel key and channel's HMAC are valid. Affected file
1480 irssi/src/silc/core/client_ops.c.
1482 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1484 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1485 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1486 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1488 * Removed channel key rekey task deleting from the function
1489 silc_server_save_channel_key. Affected file silcd/server.c.
1490 Added explicit timeout task context instead that is used to
1491 delete the task if we are registering a new task before the
1492 new task has elapsed.
1494 * When channel key rekey occurs the client library now saves
1495 the old channel key for a short period of time (10 seconds) and
1496 is able to use it in case some is still sending channel
1497 messages encrypted with the old key after the rekey. Affected
1498 file lib/silcclient/[idlist.h|client_channel.c].
1500 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Added check to the silc_server_new_id_real to not accept
1503 new ID if it is the sender's own ID. Affected file is
1504 silcd/packet_receive.c.
1506 * Assure that we do not announce ourself or the one we've
1507 sending our announcements when we're router and are announcing
1508 servers to our primary router. Affected file silcd/server.c.
1510 * Fixed silc_server_command_identify_check_client to assemble
1511 correct WHOIS packet. It send corrupted WHOIS packet and
1512 caused problem with router to router connections. Affected
1513 file silcd/command.c.
1515 Fixed also silc_server_command_whois_check the same way
1516 as for the IDENTIFY command.
1518 * Added new SilcIDListStatus to the server in the SilcIDListData
1519 structure. The status now includes the current status of
1520 the entry (like registered, resolved etc.). Affected file
1521 silcd/idlist.[ch]. Defined a bunch of different status types
1522 as well. This replaced the old boolean registered field as well.
1524 Added resolve_cmd_ident field to the SilcClientEntry structure
1525 too so that if the entry is for example being resolved so
1526 another command may attach to the same pending command reply
1527 without requiring to resolve the same entry again. This concept
1528 should optimize the WHOIS and the IDENTIFY resolving under
1529 heavy load by taking away unnecessary resolving for entries
1530 that are being resolved already.
1532 Added support for adding multiple pending commands for one
1533 command idenfier. Affected file silcd/command[_reply].[ch].
1535 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1536 before deleting the data. Otherwise the hash table will have
1537 freed data in comparison functions. Affected file is
1538 silcd/command_reply.c.
1540 * Fixed silc_idlist_replace_client_id to add the new entry to
1541 the cache with NULL nickname. Otherwise there will be invalid
1542 memory as the nickname after the nickname is freed. Affected
1543 file silcd/packet_receive.c.
1545 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1546 saved into wrong slots because the previous number of entries
1547 was not taken into account. Affected file silcd/idlist.c.
1548 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1550 * If we are router and we receive JOIN notify to a channel that
1551 does not have any users then notified client is marked as the
1552 channel founder, as it is it. The affected file is
1553 silcd/packet_receive.c
1555 * Added to the extended hash table API's table_del_*ext functions
1556 the destructor as argument too, so that the caller can decide
1557 which destructor to use or whether to use destructor at all.
1558 Affected file lib/silcutil/silchashtable.[ch].
1560 * Fixed ID Cache purging. It actually deleted the entries from
1561 the hash table after the data was freed. The hash table ended
1562 up comparing freed memory. The affected file is
1563 lib/silccore/silcidcache.c.
1565 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Fixed Irssi SILC client's KILL command's HELP syntax.
1569 * The USERS command now resolves the detailed user information
1570 if the userinfo field is missing. Affected file is
1571 lib/silcclient/command_reply.c.
1573 * Do not print error in silc_file_read if the read file does
1574 not exist. Just silently return NULL. Affected file is
1575 lib/silcutil/silcutil.c.
1577 * Fixed the silc_log_output to not wine about NULL filename
1578 and to not create some bogus " " filename. Affected file is
1579 lib/silcutil/silclog.c.
1581 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1583 * Fixed various printing bugs on the user interface in the
1584 Irssi SILC Client. Minor changes that were forgotten from
1587 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1589 * Fixed the configure.in.pre and the compilation and distribution
1590 environment to support the new autoconf 2.52. That version is
1591 now required to compile the CVS trunk.
1593 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1596 to generally parse user@fqdn format strings. Affected file
1597 lib/silcutil/silcutil.c.
1599 * Added nickname_format and nickname_force_format fields to the
1600 SilcClientParams structure. The first one defines the format
1601 for the nicknames that the library will enforce if the receives
1602 multiple same nicknames. The second one is boolean value and
1603 can be used to force the library to always enforce the format
1604 to the nicknames regardles whether there are multiple nicknames
1605 or not. This configurable formatting was employed to flexibly
1606 support accessing multiple nicknames from the user interface.
1607 The userinterface can now set the nicknames to what ever format
1608 they prefer. Affected file lib/silcclient/silcapi.h.
1610 Added function silc_client_nickname_format to the file
1611 lib/silcclient/idlist.c. It performs the nickname formatting.
1613 Added new field `hostname´ to the SilcClientEntry context.
1614 It holds the hostname of the client. Affected file is
1615 lib/silcclient/idlist.h.
1617 * Irssi SILC Client sets the nicknames in nick@hostn format.
1618 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1619 irssi/src/silc/core/silc-core.c.
1621 The WHOIS printing now also shows both the real nickname and
1622 the formatted nickname so that user knows how to access the
1623 user if there are multiple same nicknames cached. Affected
1624 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1625 printing formatting too to take the hostname now as a separate
1626 argument. The Affected file is
1627 irssi/src/fe-common/silc/modules-formats.[ch].
1629 * Changed the silc_client_get_clients_local to accept the formatted
1630 nickname as argument. It accepts the real nickname too but the
1631 formatted nickname can be used to find the true entry from
1632 multiple entries. Affected file lib/silcclient/silcapi.h and
1633 lib/silcclient/idlist.c.
1635 * Added nickname_format_parse field to the SilcClientParams.
1636 It is a callback function provided by the application to parse
1637 the nickname out of the formatted nickname string. The library
1638 calls it to get the nickname from the formatted string. Since
1639 the application generally knows better the format of the nickname
1640 string it parses it instead of the library, even though library
1641 encodes the formatted string. If the callback function is not
1642 provided then the library will use the string as is. The
1643 affected file is lib/silcclient/silcapi.h.
1645 * All the nickname strings passed to the client library in
1646 commands are now expected to be formatted nickname strings.
1647 If the command does not support the formatted nickname string
1648 it will assume that the sent string is the actual nickname.
1649 Affected file lib/silcclient/command.c.
1651 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Added public key authentication support to OPER and SILCOPER
1654 commands in the client library. Affected file is
1655 lib/silcclient/command.c.
1657 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Changed the get_auth_methdod client operation to be asynchronous.
1660 It can be async if the application resolves the authentication
1661 method from the server during the negotiation. Added new
1662 SilcGetAuthMeth completion callback that the application will
1663 call after resolving the authentication method.
1665 Added function silc_client_request_authentication_method that
1666 the application can use to resolve the authentication method
1667 from the server. Added also SilcConnectionAuthRequest callback
1668 that the library will call after the server has replied. The
1669 application can call this function if it does not know the
1670 current authentication method.
1672 Affected files are lib/silcclient/client.c and
1673 lib/silcclient/silcapi.h.
1675 * The Irssi SILC client now automatically resolves the authentication
1676 method incase any configuration information is not present (and
1677 currently there never is). The affected file is
1678 irssi/src/silc/core/client_ops.c.
1680 * Fixed public key authentication from the client library.
1681 Affected file lib/silcclient/protocol.c. Changed also the
1682 protocol specification about the public key authentication in
1683 the connection authentication protocol. The actual data to be
1684 signed is now computed with a hash function before signing.
1686 * Fixed the public key authentication from the server as well.
1687 Affected file silcd/protocol.c.
1689 * Removed the mlock()'s from the memory allocation routines.
1690 Affected file lib/silcutil/silcmemory.c. The ./configure does
1691 not check anymore for the mlock(). Affected file is
1694 * Fixed USERS command in server to allow the execution of the
1695 command for private and secret channels if the client sending
1696 the command is on the channel. Affected file silcd/command.c.
1698 * Fixed silc_client_get_clients_local to return the clients
1699 count correctly. It could return wrong value. Affected file
1700 lib/silcclient/idlist.c.
1702 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1704 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1705 types. The assembler optimizations seemed not to like 64-bit
1706 data types. The assmebler optimizations thus are now enabled
1707 also for BSD systems as opposed to only enable them for Linux.
1709 * Do not check for threads at all on BSD systems. Affected
1710 file configure.in.pre.
1712 * Removed -n and -h options from the Irssi SILC Client since
1713 they are not used in silc.
1715 * Fixed the prime generation to assure that the first digit
1716 of the generated random number is not zero since our conversion
1717 routines does not like number strings that starts with zero
1718 digit. If zero digit is seen the random number is regenerated.
1719 This caused some corrupted RSA keys when the zero first digit
1720 was met. Affected file lib/silcmath/silcprimegen.c.
1722 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Fixed WIN32 configuration in the ./configure script.
1725 Fixed to include xti.h on environments that has it.
1726 Patches by Carsten Ilchmann and andrew.
1728 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1730 * Changed the silc_id_create_client_id to be collision
1731 resistant. It is now assured that there cannot be created
1732 two same client ID's. I suspect that some weird bugs in
1733 the server were actually caused by duplicate Client IDs.
1734 Affected file silcd/serverid.[ch]. A router receiving
1735 new ID now also assures and informs the sending server
1736 if the ID caused collision.
1738 * Changed the silc_id_create_channel_id to also assure that
1739 there are no collisions.
1741 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1743 * Statement about ignoring the Mutual Authentication flag when
1744 performing rekey with PFS was a bit misleading. It is ignored
1745 if it was set in the initial negotiation, it cannot be even
1746 set in the rekey. Fixed in the ke-auth draft. Started the
1747 new versions of the protocol drafts in the doc/.
1749 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1751 * Fixed a bug in silc_client_command_identify_save when saving
1752 new channel information. The channel name was no duplicated
1753 and caused crash on exit. Affected file is
1754 lib/silcclient/command_reply.c.
1756 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1758 * Fixed the getkey command handling in the server. Send just
1759 empty OK reply to the sender if the key could not be fetched
1760 (but everything else was ok, like the key just was not available).
1761 Changed the public key parameter to optional in the protocol
1762 specs so that empty OK reply can be sent. Affected file
1765 Added a message to Irssi SILC client to tell to user if the
1766 server did not return a public key.
1768 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1770 * Fixed a channel key regeneration bug. It registered new
1771 timeout tasks exponentially until all system resources were
1772 used. Affected file silcd/server.c.
1774 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Added the SILC Document generator to the scripts/silcdoc.
1777 It can be used to generate the Toolkit Reference Manual out
1778 of the source tree. Internally it will also use the RoboDoc
1779 generator now imported in util/robodoc.
1781 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * Added couple of return's in rekey protocol if error orccurred
1784 during the protocol. The execution must be terminated.
1785 Affected file silcd/protocol.c. Also, terminate the protocol
1786 always with timeout.
1788 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * The client's Client ID was created initally from the wrong
1791 nickname (it could have been in format nick@host) in the
1792 silc_server_new_client. Affected file silcd/packet_receive.c
1794 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1796 * Added some SILC_LOG_ERROR's to various error conditions
1797 if client could not be added to ID cache. Affected files
1798 silcd/packet_receive.c and silcd/server.c.
1800 * When client's sock->user_data is freed, NULL also the
1801 client->router and client->connection pointers. Added check
1802 for these pointers being NULL to various places around the
1803 code. Affected file silcd/server.c.
1805 * Added client->data.registered == TRUE checks to various
1806 places around the code to assure that unregistered client's
1807 are not handled when it is not allowed. Affected file
1810 * Added `bool registered' fields to all
1811 silc_idlist_[server|client]_get_* routines to indicate whether
1812 the fetched client needs to be registered or not. Affected
1813 file silcd/idlist.[ch].
1815 * Add your own entry as registered to the ID cache in the
1816 server. Affected file server.c.
1818 * Fixed a bug in silc_server_new_server. The SilcServer was
1819 set as the new server's context instead of SilcServerEntry.
1820 This naturally caused some weird bugs.
1822 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Do not delete the channel rekey task when adding it
1825 for in silc_server_create_channel_key.
1827 * Changed the silc_server_create_channel_key to return
1828 TRUE or FALSE to indicate the success of the channel key
1831 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Fixed MSVC++ project files and added missing files to
1834 Makefiles under win32/.
1836 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Do not add TCP_NODELAY flag if the operating system
1839 does not have it defined. Affected files are
1840 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1842 * Fixed buffer overflow from Irssi SILC Client. Affected
1843 file irssi/src/fe-common/core/themes.c.
1845 * Fixed double free in client library in the file
1846 lib/silcclient/client.c when disconnecting from server.
1848 * Applied double free patch from cras to Irssi SILC client.
1849 Affected files irssi/src/core/[modules/expandos].c
1851 * Fixed the disconnection handling to Irssi SILC Client.
1852 The application must call silc_client_close_connection
1853 in ops->connect client operation in case of failure of
1854 the connection. Affected file is
1855 irssi/src/silc/core/client_ops.c.
1857 * Do not set sock->protocol to NULL in the function
1858 silc_client_close_connection after executing the protocol's
1859 final callback since the sock might not be valid anymore.
1860 Affected file lib/silcclient/client.c.
1862 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Do not enable SILC_THREADS if the linking with libpthread
1865 did not happen. Affected file configure.in.pre.
1867 * Added notion to protocol specification that server must
1868 verify the sent authentication payload with CMODE when
1869 setting the channel founder key. Implemented it to the
1870 server. Affected file silcd/command.c.
1872 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Added _EXTRA_DIST SILC distribution variable to the
1875 distributions file. It is used to conditionally add extra
1876 files or directories to the specific distribution. Affected
1877 files ./prepare, Makefile.am.pre and distributions.
1879 Removed the `_' from the start of the distribution names.
1882 * Added README.WIN32 for instructions to compile the Toolkit
1885 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Fixed a double free in disconnection in the server. Affected
1888 file is silcd/server.c.
1890 * Fixed the lib/silcske/groups.c to work now also with GMP
1891 MP library. The string conversion did not work when using
1892 specific base and the base is indicated in the string as well.
1894 * Created win32/ directory which now includes MSVC++ specific
1895 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1896 It will appear only in the toolkit distribution
1898 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Changed the key material distribution function in case when
1901 the hash output is too short. The data is now concatenated
1902 a bit differently than it used to. Made the change to the
1903 SKE protocol specification.
1905 * Added better GMP detection to configure.in.pre. A patch
1908 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Fixed a minor bug in SKE that might cause some problem on
1911 some platforms. Affected file lib/silcske/silcske.c.
1913 * Added the cookie checking for initiator in the SKE. It checks
1914 that the responder returns the sent cookie unmodified. The
1915 affected file is lib/silcske/silcske.c. Added new SKE
1916 error type INVALID_COOKIE that can be sent during the
1917 negotiation. Fixed some memory leaks as well.
1919 * Added the "invalid cookie" error message to Irssi SILC client's
1922 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Added `task_max' field to the SilcClientParams to indicate
1925 the maximum tasks the scheduler can handle. If set to zero,
1926 default values are used. Affected file lib/silcclient/silcapi.h.
1928 * Fixed memory leaks in silc_client_close_connection. Affected
1929 file lib/silcclient/client.c.
1931 * Added silc_client_del_client_entry to client library to free
1932 all memory of given client entry. Affected file is
1933 lib/silcclient/idlist.[ch].
1935 * Added new functions silc_client_del_channel and
1936 silc_client_del_server to delete channel and server entries.
1937 Affected file lib/silcclient/[silcapi.h/idlist.c].
1939 * Removed silc_client_del_client_by_id from silcapi.h.
1941 * Fixed the INFO command to return the server's own info
1942 correctly when querying by Server ID. Affected file is
1945 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Removed the non-blocking settings in WIN32 code in the
1948 silc_sock_[read/write] and added SleepEx instead. Affected
1949 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1950 of input data is now checked with FIONREAD and ioctlsocket.
1952 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1954 * Call silc_schedule_task_del_by_context in the
1955 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1956 Affected file lib/silccore/silcprotocol.c.
1958 * Call silc_protocol_cancel for active protocols in the
1959 silc_server_close_connection if the funtion
1960 silc_server_free_sock_user_data has not been called.
1961 Affected file silcd/server.c.
1963 * Generic tasks cannot be deleted using the del_by_fd
1964 task deleting function since generic tasks does not match
1965 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1967 * Added a notion to SILCOPER help file that the SILCOPER works
1968 only on router server, not on normal server.
1970 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1972 * Added for WIN32 support for the new scheduler as well.
1973 Affected file lib/silcutil/win32/silcwin32schedule.c.
1975 * Fixed the SHA1 implementation to work on various platforms.
1977 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1980 API. It is part of the scheduler now. Everything else is
1981 as previously but some functions has changed their names.
1982 Checkout the lib/silcutil/silcschedule.h for the interface.
1983 Updated all applications to use the new interface. Affected
1984 files are lib/silcutil/silcschedule.[ch].
1986 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Found a bug in the SKE implementation. The HASH value,
1989 specified by the protocol, was not computed correctly. The
1990 public key of the responder was not added to the computation
1991 even though it is mandatory. Affected file lib/silcske/silcske.c.
1992 This unfortunately causes incompatibilities with older
1993 clients and servers.
1995 * Added WIN32 specific network init and uninit functions:
1996 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1997 the Winsock2. Affected file lib/silcutil/silcnet.h and
1998 lib/silcutil/win32/silcwin32net.c.
2000 * Set the socket always to nonblocking mode on WIN32 after
2001 reading data or writing data. Affected file is
2002 lib/silcutil/win32/silcwin32sockconn.c.
2004 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2006 * Fixed various compilation problems under WIN32. Affected
2007 files lib/silcutil/win32/silcwin32thread.c and
2008 lib/silcutil/win32/silcwin32schedule.c.
2010 * Removed all _internal.h #includes from public header
2011 files. Internal headers must never be included from
2014 Removed also the lib/silcske/payload_internal.h file.
2016 * All include files that may be needed (public and some others
2017 included by the public headers) by application developers are
2018 now copied to the ./includes directory. It does not copy any
2019 internal headers. Affected file Makefile.defines.pre and all
2020 Makefile.am's under lib/ and subdirs.
2022 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2024 * Do not change the ~/.silc directory's permissions automatically.
2025 Affected file irssi/src/silc/core/clientutil.c.
2027 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2029 * Do not cancel the protocol in silc_server_close_connection
2030 it might cause recursion. Now cancelled in the function
2031 silc_server_free_sock_user_data. Affected file silcd/server.c.
2033 * Fixed the silc_server_remove_clients_by_server to regenerate
2034 the channel keys correctly finally. Added also new function
2035 silc_server_remove_clients_channels to actually do it.
2036 Affected file silcd/server.c.
2038 * Fixed the silc_server_new_channel to not crash by giving
2039 wrong router to the new channel. Affected file is
2040 silcd/packet_receive.c.
2042 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2044 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2045 which is given as argument to the silc_client_alloc now.
2046 It can be used to configure the client and set various parameters
2047 that affect the function of the client.
2049 * The USERS command in server did not check whether the channel
2050 is private or secret. Affected file silcd/command.c.
2052 * Added new argument to the USERS command in protocol specification.
2053 The USERS command now can take the channel name as argument
2054 as well. Added support for this in client and server and
2055 updated the protocol specs.
2057 * Completed the GETKEY command in client. It can be now used
2058 to fetch also servers public key not only some clients.
2059 Affected files lib/silcclient/command[_reply].c.
2061 * Added silc_client_get_server to return server entry by the
2062 server name. Affected files lib/silcclient/silcapi.h and
2065 * Redefined the IDENTIFY command in protocol specification to be
2066 more generic. It now can be used to query information about
2067 any entity in the SILC Network, including clients, servers and
2068 channels. The query may be based either the entity's name
2069 or the ID. Added support for this in both client and server.
2071 Affected files silcd/command.c and lib/silcclient/command.c
2072 and command_reply.c.
2074 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2075 the _from_client and _from_server functions. Affected file
2078 * Added silc_client_get_channel_by_id_resolve to the file
2079 lib/silcclient/silcapi.h to resolve channel information by
2080 its ID. Added also silc_client_get_channel_by_id that
2081 does not resolve it from the server.
2083 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2085 * Added SilcServerEntry context into the client library
2086 to represent one server. The INFO command now allocates
2087 these to save the resolved server info. For now on the
2088 client library will also keep information about servers,
2089 connected and resolved with INFO.
2091 The INFO command now allocates the SilcServerEntry context
2092 and saves the server info there. The COMMAND_REPLY in
2093 the INFO now returns the parameters to application in
2094 same order as defined in the protocol specification.
2096 The entries are cached in the client->server_cache.
2098 * The INFO command is now issued after received the Client ID
2099 from the server. Affected file lib/silcclient/client.c.
2101 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2102 to the application as the mode changer might be server.
2103 It is guaranteed that NULL is not returned anymore to the
2104 application. Affected file lib/silcclient/client_notify.c.
2106 The ID Type is now also passed to the application so that
2107 it can check whether the returned entry is SilcClientEntry
2110 Added new function silc_client_get_server_by_id to return
2111 the server entry by ID. Affected files are the
2112 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2114 * Do not create the channel in the Irssi SILC Client when issuing
2115 the JOIN command but when received the sucessful JOIN command
2116 reply. Otherwise the channel might get created even though we
2117 could not join it. The Affected file is
2118 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2120 * Fixed a channel joining bug in router. The router must also
2121 check the channel modes, invite and ban lists etc. when serving
2122 the JOIN command sent by normal server. Affected file is
2123 silcd/command.c. The router now resolves the client's
2124 information from the server who sent the JOIN command if it
2125 does not know it, and processes the JOIN command only after
2128 * Changed the SilcCommandCb to take new argument; void *context2.
2129 Affected file lib/silccore/silccommand.h
2131 The second argument in the command callbacks in the server now
2132 includes the SilcServerCommandReplyContext if the command was
2133 called as pending command callback from the command reply.
2134 Otherwise it is NULL. When called as pending the status of the
2135 command reply will be checked and if it was erronous the
2136 error will be sent to the original sender of the command.
2137 This way the client always receives the error messages even
2138 though the server was actually the one who received the error
2139 when it resent the command to router, for example. Affected
2140 files silcd/command[_reply].[ch].
2142 * Fixed sending WHOWAS command's error message to client if
2143 the requested client could not be found. It was missing.
2146 * Changed the CMODE and CUMODE commands reply arguments in the
2147 protocol specification. The Channel ID is now sent in both
2148 of the commands to identify the channel. Implemented this
2149 new feature to the client and server. Affected files
2150 lib/silcclient/command_reply.c and silcd/command.c.
2152 * Made better checks for invite and ban lists in the JOIN
2153 command in server. Affected file silcd/command.c.
2155 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2157 * The server now performs the incoming host IP/DNS lookup
2158 using the silc_socket_host_lookup and thus does not block
2159 the server anymore. Affected file silcd/server.c.
2161 * Completed the multi-thread support for SILC Scheduler in
2162 the lib/silcutil/silcschedule.c.
2164 * Fixed the configure.in.pre to detect the pthread correctly
2167 * Fixed a deadlock in silc_task_queue_wakeup in the file
2168 lib/silcutil/silctask.c.
2170 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2172 * Added new function silc_schedule_wakeup that is used in
2173 multi-threaded environment to wakeup the main thread's
2174 schduler. It needs to be used when a thread adds a new task
2175 or removes a task from task queues. After waking up, the
2176 scheduler will detect the task queue changes. If threads
2177 support is not compiled in this function has no effect.
2178 Implemented the wakeup mechanism to both Unix and WIN32
2179 systems. Affected files are lib/silcutil/silcschedule.[ch],
2180 lib/silcutil/unix/silcunixschedule.c and the
2181 lib/silcutil/win32/silcwin32schedule.c.
2183 * Added new function silc_task_queue_wakeup to wakeup the
2184 scheduler by the specified task queue. Affected file
2185 lib/silcutil/silctask.[ch].
2187 * The silc_socket_host_lookup_start now wakes up the scheduler
2188 after adding the timeout task. Affected file is
2189 lib/silcutil/silcsockconn.c.
2191 * The silc_socket_host_lookup is synchronous now if the threads
2192 support is not compiled in. However, the callback is still
2193 called asyncronously through the scheduler, anyway. Affected
2194 file lib/silcutil/silcsockconn.c.
2196 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2198 * Added new function silc_socket_host_lookup to perform
2199 asynchronous IP and FQDN lookups for the socket connection.
2200 Affected files lib/silcutil/silcsockconn.[ch].
2202 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2205 that may or may not compile the mutex support in.
2207 Changed the silc_mutex_alloc interface. It allocates the
2208 mutex now to the sent pointer and returns TRUE or FALSE.
2210 Affected file lib/silcutil/silcmutex.h.
2212 * Wrote the SILC Task Queue interface to support multi-threads.
2213 Affected file lib/silcutil/silctask.[ch].
2215 * Wrote the SILC Scheduler to support multi-threads. Affected
2216 file lib/silcutil/silcschedule.c.
2218 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2220 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2221 in lib/silcutil/win32/.
2223 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * Defined SILC Mutex API and SILC Thread API and implemented
2226 them for Unix. Affected files are
2227 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2228 lib/silcutil/unix/silcunixmutex.c and
2229 lib/silcutil/unix/silcunixthread.c.
2231 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2233 * Fixed the silc_server_remove_clients_by_server's channel
2234 key re-generation. The hash table handling was incorrect
2235 and would not work with many channels. Affected file is
2238 * Fixed some memory leaks around the server code.
2240 * Rewrote the silc_server_get_users_on_channel to support IPv6
2241 based Client ID's. Affected file silcd/server.c.
2243 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2244 specification. However, a separate document must be written
2245 to define the detailed signing procedure and the payload
2246 associated with the flag. Defined the flag to the
2247 lib/silccore/silcchannel.h as well.
2249 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2251 * Changed the dynamic tables to static size tables in the
2252 lib/silccrypt/silchmac.c.
2254 * Removed GCC dependencies from the code. A patch by cras.
2256 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Do not show the error "Error receiving packet bla bla"
2259 in server if it really was not an error (-2 means that reading
2260 is pending). Affected file silcd/server.c.
2262 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2264 * Fixed a possible crash in silc_server_remove_clients_by_server
2265 in silcd/server.c. Fixed there also some memory leaks.
2267 * Fixed the silc_idlist_replace_client_id. It could replace
2268 wrong key in the hash table. Affected file silcd/idlist.c.
2270 * Do not check whether there are global users on the channel
2271 if the channel->global_users is FALSE. Affected functions
2272 silc_server_remove_from_one_channel and
2273 silc_server_remove_from_channels in silcd/server.c. Also,
2274 do not check if the removed client is local as we can be
2275 sure that global client was not removed from the channel
2276 and checking for global users is not needed.
2278 * The silc_server_remove_clients_by_server now re-generates
2279 the channel keys correctly for those channels that had
2280 clients removed from them. Affected file silcd/server.c.
2282 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2284 * Found the reason of random crashes in the server. We weren't
2285 ignoring the SIGPIPE signal (which can be sent in write())
2286 and it crashed the server. Affected file silcd/silcd.c.
2288 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * Assure that sock->user_data is not NULL in the function
2291 silc_server_packet_send in silcd/packet_send.c.
2293 * Disconnect the remote connection if it could not be added
2294 to any ID lists in the server. The affected file is
2297 * Check in silc_server_packet_send[_real/dest] that the
2298 socket is not disconnecting and ignore the data if it is.
2299 Affected file silcd/packet_send.c.
2301 * Define inline to __inline on native WIN32 compilation.
2302 Affected file includes/silcwin32.h.
2304 * Added some explicit type casts for inline code since MSVC
2305 require them. Affected files lib/silcutil/silcbuffer.h,
2306 lib/trq/silcdlist.h and lib/trq/silclist.h.
2308 * Print warning in log files from now on if the packet
2309 decryption fails. Affected file silcd/server.c.
2311 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2313 * Changed the `say' client operation's interface to accept
2314 new `type' argument to indicate the type of the message sent
2315 by the library. The application may filter the library's
2316 messages according the type. The affected file is the
2317 lib/silcclient/silcapi.h.
2319 * Added two new functions to lib/silcclient/silcapi.h:
2320 silc_client_del_client and silc_client_del_client_by_id.
2321 Affected file lib/silcclient/idlist.c.
2323 * Moved the clientincludes.h from includes/ to silc/ and
2324 serverincludes.h from includes/ to silcd/.
2326 * The modes for the CMODE and CUMODE are now passed as
2327 uint32 for application with COMMAND_REPLY. The affected
2328 file is lib/silcclient/command_reply.c.
2330 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2332 * /WHOIS without arguments shows client's own information.
2333 Affected file lib/silcclient/command.c.
2335 * Changed PING to not accept any arguments. The specs
2336 says that client can ping only the connected server so
2337 requiring an argument is not needed. Affected file is
2338 lib/silcclient/command.c.
2340 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2342 * Fixed a fatal bug in private message sending and reception
2343 encryption and decryption when using private message keys.
2344 The implementation was incorrect and did not follow the
2345 specification. It causd that some of the message were
2346 lost since it did not use the sending and receiving keys
2347 as the protocol suggests. This has been fixed and will cause
2348 incompatibilities with older clients when sending private
2349 message encrypted with private message keys. Affected files
2350 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2351 and various other in Irssi SILC Client.
2353 Added `responder' boolean argument to the functions
2354 silc_client_add_private_message_key[_ske] to indicate when
2355 the key is added as responder or initiator of the key
2358 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Removed the silc_ske_check_version function and created
2361 a SilcSKECheckVersion callback. Added also a function
2362 silc_ske_set_callbacks that is now used to set all SKE
2363 callbacks. The callback functions are not given to
2364 the SKE functions anymore, but this function is used to
2367 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2369 * Added `silc_version' argument to the silc_client_alloc
2370 to define the version of the application for the library.
2371 The library will use the version string to compare it
2372 against the remote host's (usually a server) version
2373 string. Affected file lib/silcclient/silcapi.h
2375 * Added the KE protocol context to Key Agreement context
2376 in client library so that we can abort the SKE if it
2377 is in process when we get timeout. Affected file is
2378 lib/silcclient/client_keyagr.c.
2380 * Do not resolve the client ID forever if it returns in the
2381 first time that such client does not exist. This was done
2382 for example with private message. Affected file is
2383 lib/silcclient/client_prvmsg.c.
2385 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * Do not add regex.h for WIN32. The affected file
2388 includes/silcincludes.h.
2390 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2391 not work yet 100%. It generates the DLL's automatically
2392 when compiling with --with-win32 under cygwin.
2394 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * lib/contrib/regex.c is not compiled on WIN32.
2398 * Added silc_net_get_socket_opt function to the
2399 lib/silcutil/silcnet.h.
2401 * Added includes/silcwin32.h for WIN32 specific includes
2404 * Do not use ptime structure or any of the posix process
2405 functions on WIN32 in lib/silccrypt/silrng.c.
2407 * Added silc_gettimeofday to provide generic function
2408 for struct timeval on all platforms. Added the function
2409 to lib/silcutil/silcutil.h.
2411 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2414 library as they clearly belong there. As a plus side we
2415 can make the actual socket connection routines platform
2418 Added also new generic function silc_socket_read and
2419 silc_socket_write (that used to be silc_packet_[read/write].
2420 The implementation of these are platform specific.
2422 * Added WIN32 specific routines of silc_socket_[read/write]
2423 to lib/silcutil/win32/silcwin32sockconn.c.
2425 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2427 * Added preliminary support for native WIN32 compilation under
2428 cygwin (using the -mno-cygwin option for GCC) to the
2429 ./configure.in.pre. The --with-win32 now prepares the
2430 compilation for native WIN32.
2432 * Rewrote the SILC Scheduler interface in the file
2433 lib/silcutil/silcschedule.h. The scheduler is now context
2434 based and does not have anymore any global static scheduler.
2435 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2436 and created lib/silcutil/win32 directory for WIN32 based
2439 * Added Unix specific network routines to the
2440 lib/silcutil/unix/silcunixnet.c and the old
2441 lib/silcutil/silcnet.c includes now only generic routines.
2443 Added WIN32 specific network routines to the
2444 lib/silcutil/win32/silcwin32net.c.
2446 * Added Unix specific utility functions from the
2447 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2449 * Added WIN32 SILC Scheduler to the file
2450 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2453 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Do not handle JOIN notify in the server if the target client
2456 is not registered (idata->registered == FALSE). The affected
2457 file is silcd/packet_receive.c.
2459 * Update the nickrec->founder in event_cumode in the Irssi SILC
2460 client. Affected file irssi/src/silc/core/silc-channels.c.
2462 * Fixed the CUMODE_CHANGE notify handling in the server when
2463 server and router are announcing their clients on channels.
2464 Now the mode changes are saved and notified correctly. The
2465 affected file is /silcd/packet_receive.c.
2467 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2468 They really did not replace the cache entry in the ID Cache.
2469 Now they do that. Affected file silcd/idlist.c.
2471 * Fixed the KICK notify handling in the Irssi SILC client to
2472 update the channel records so that the kicked client does not
2473 appear to be on the channel. The affected file is
2474 irssi/src/silc/core/silc-channels.c.
2476 * Always update the conn->current_channel when executing command
2477 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2479 * Fixed the KILL notify handling in Irssi SILC client to remove
2480 the killed client on all channels.
2482 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2484 * Fixed the silc_parse_command_line to remove extra spaces
2485 from the start and end of the arguments. Affected file is
2486 lib/silcutil/silcutil.c.
2488 * Cancel and free any active protocol in the function
2489 silc_server_close_connection. Affected file silcd/server.c.
2491 * Cancel and free any active protocol in the function
2492 silc_client_close_connction. Affected file is
2493 lib/silcclient/client.c.
2495 * Do not execute the KILL command for clients that are in
2496 history (ie. they are not in the network). Affected file is
2499 * Fixed KILL notify handling, client does not crash anymore.
2500 Affected file irssi/src/silc/core/silc-channels.c.
2502 * Reduced the default packet buffer size from 2048 to 1024 in
2503 lib/silccore/silcpacket.c.
2505 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2506 counter to the SKE context that is incresed when the SKE library
2507 performs async operation outside the library. If the outside
2508 process frees the SKE context and FREED status will be set
2509 and the library will detect after the sync operation that the
2510 libary is freed. The affected files are
2511 lib/silcske/silcske[_status].[ch].
2513 * Resolve the client entry information in the function
2514 silc_client_channel_message to assure that NULL pointer is not
2515 passed as client entry to the application. */
2517 * Fixed the task timeout calculation to assure that there is
2518 never negative timeouts. The affected file is
2519 lib/silcutil/silcschedule.c.
2521 * Fixed the channel user mode notification sending in server.
2522 It was sent point-to-point to the router (or to server by router)
2523 but it needs to be destined to a channel. The routines now
2524 supports sending the channel user mode notifys to the channels
2525 when announcing clients and channels. Affected files are
2526 silcd/server.c and silcd/packet_receive.c.
2528 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2529 It did not actually replace the old channel entry in the cache.
2530 Affected file lib/silcclient/client_notify.c.
2532 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2534 * Fixed a possible crash in silc_packet_send_prepare. It now
2535 assures always that there is enough space in the buffer and
2536 at the tail area of the buffer (for MAC).
2538 Fixed the inbound buffer reallocation in silc_packet_read.
2539 It was old code and did not handle the reallocation correctly.
2542 The affected file is lib/silccore/silcpacket.c.
2544 * Fixed buffer overflow in silc_parse_nickname in the file
2545 lib/silcutil/silcutil.c.
2547 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2549 * make install generates new server keys only if there is not
2552 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2554 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2555 Added check that if the NOREPLY is set then we will not send
2556 the away message. This avoids infinite loop of away messages
2557 if both clients are away. The affected file is
2558 lib/silcclient/client_prvmsg.c.
2560 * Fixed client crash if /NICK was given without arguments.
2561 Affected file lib/silcclient/command.c.
2563 * Server does not send the invite list in INVITE command back
2564 to the client if the list was not altered. Added this notion
2565 to the protocol spec as well. Affected file silcd/command.c.
2567 Fixed possible crash in INVITE command by checking the
2568 value of silc_server_get_client_route command.
2570 * Fixed the INVITE notify type handling. The arguments are now
2571 taken in correct order and client does not crash. The affected
2572 file is irssi/src/silc/core/silc-channels.c.
2574 Removed the "Inviting xxx to channel" message from the
2575 client library away and let the application handle it.
2576 Affected file lib/silcclient/command.c. Added that message
2577 to Irssi SILC client's message formats.
2579 * Fixed CMODE command crash in client. It now checks the
2580 amount of arguments correctly and does not crash. The affected
2581 file is lib/silcclient/command.c.
2583 * Do not create new channel automatically in silc_channels_join
2584 but check whether the channel by that name already exists.
2585 Affected file irssi/silc/core/silc-channels.c.
2587 * Do not send the SERVER_SIGNOFF to router if the disconnected
2588 entity was the router. Affected file silcd/server.c.
2590 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2591 SILC client as it was missing from there.
2593 Added the handling of the KICK notify to the Irssi SILC client
2594 as it was missing. Added "you have been kicked" message to
2595 Irssi SILC client's message modules formats.
2597 Added the handing of the KILL notify to the Irssi SILC client
2598 as it was missing. Added the kill message module formats
2601 The affected file is irssi/src/silc/core/silc-channels.c.
2603 * The router did not save the channel mode the server announced.
2604 Affected file silcd/packet_receive.c.
2606 * Fixed a possible crash in INFO command in server. If the
2607 server did not provide the server info it crashed. Affected
2608 file silcd/command.c.
2610 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Fixed the GETKEY command in the server to check also the
2613 global list. Otherwise the GETKEY would not work correctly
2614 in normal SILC server. Affected file silcd/command.c.
2616 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Fixed GETKEY crash, it crashed if the command did not succseed.
2620 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2622 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2623 is now real and not just an macro interface to GMP.
2625 Removed the entire GMP from the source tree and imported new
2626 NSS MPI library instead. Reason for removing GMP is that it is
2627 extremely large and compiles extremely slow. The NSS MPI
2628 is only a few files and compiles in less than 10 seconds.
2629 The speed is also about the same as GMP. The MPI is imported
2630 to lib/silcmath/mpi.
2632 If the system has GMP installed we will still use the GMP.
2633 If it is not then the NSS MPI will be compiled.
2635 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Merged a long nickname (127 characters long) crash bugfix from
2638 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2640 * Merged a freed memory reference bugfix from Irssi CVS tree.
2641 Affected file irssi/src/core/commands.c.
2643 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2645 * Added the server's public key sving and verification to the
2646 server when performing the SKE. This was missing and the
2647 remote server's (or router's) public key was accepted without
2648 checking whether we have it previously or trust it at all.
2649 Affected file silcd/protocol.c.
2651 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2653 * Check in the silc_server_timeout_remote if protocol is active
2654 and make sure that the protocol's final callback is called so
2655 that all memory if freed. Affected file silcd/server.c.
2657 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2659 * silc_server_whois_send_reply crashed the server if the nickname
2660 was 127 characters long. Affected file silcd/command.c.
2662 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Added sanity check to the silc_server_new_client. If the hostname
2665 is provided inside username then check that the provided hostname
2666 really is the same as the resolved one. If the hostname was not
2667 resolved then check it from the public key. Affected file is
2668 silcd/packet_receive.c.
2670 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2671 if the server disconnected us and the connection is not valid
2672 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2674 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2675 the library to the lib/silcutil/silcutil.[ch].
2677 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Close log file after open. Affected file
2680 lib/silcutil/silclog.c.
2682 * Check whether sock == NULL in silc_client_send_packet and return
2683 if it is. Affected file lib/silcclient/silcclient.c.
2685 * Check rec->entry == NULL in the Irssi SILC Client before
2686 sending the channel message. Affecte file is
2687 irssi/src/silc/core/silc-servers.c.
2689 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2691 * Merged a splitted window bugfix from Irssi CVS tree. The
2692 affected file is irssi/src/fe-text/textbuffer-view.c.
2694 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2695 It did not print nickname.
2697 * Improved the distributions system a bit.
2699 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2701 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2702 irssi/src/fe-text/gui-window.c.
2704 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2705 to in-active server. The affected file is
2706 irssi/src/silc/core/client_ops.c.
2708 * Resolve the client in USERS command reply if the entry does
2709 not have username resolved. The affected file is
2710 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2711 command to WHOIS command to really resolve stuff. The USERS
2712 is not used any more in any critical section so WHOIS can
2713 be used even though it might be slower than IDENTIFY.
2715 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2718 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2720 * Changed the protocol API a bit more consistent in the
2721 lib/silccore/silcprotocol.[ch].
2723 * Changed the following headers to ROBODoc format:
2725 lib/silccore/silcpayload.h
2726 lib/silccore/silcprotocol.h
2727 lib/silccore/silcsockconn.h
2729 All core library headers are now formatted.
2731 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * Fixed a bug in Irssi SILC client; do not show that you are
2734 server/router operator if you really are not. Affected file is
2735 irssi/src/silc/core/client_ops.c.
2737 * Renamed silc_command_free_payload to silc_command_payload_free.
2738 Affected file lib/silccore/silccommand.h
2740 * Added silcmath.h to include the prototoypes of various routines
2741 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2744 * Changed the following headers to ROBODoc format:
2746 lib/silccore/silcchannel.h
2747 lib/silccore/silccommand.h
2748 lib/silccore/silcid.h
2749 lib/silccore/silcidcache.h
2750 lib/silccore/silcmode.h
2751 lib/silccore/silcnotify.h
2752 lib/silccore/silcpacket.h
2753 lib/silcmath/silcmath.h
2755 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2757 * Added checking to the server code not to start the server if
2758 ciphers and stuff are not configured properly. Affected files
2759 silcd/serverconfig.[h] and silcd/server.c.
2761 * Changed the layout of the header files of the public interfaces
2762 in the SILC libraries. The new layout supports ROBODoc
2763 documentation tool (and some others) so that it is easy to create
2764 a library reference manual. All the other headers and source
2765 code must still follow the CodingStyle document. Also source
2766 code must not include these ROBODoc stuffs, only the headers.
2767 Furthermore, all public interface headers must now be named
2768 by using `silc' prefix, example: silcapi.h, silccipher.h.
2769 Some files were renamed due to this. All the other headers
2770 must not be used as public interfaces. I will update the
2771 CodingStyle document later. Changed following headers, so far:
2773 lib/silcclient/silcapi.h
2774 lib/silccore/silcauth.h
2775 lib/silccore/silcprivate.h
2776 lib/silccrypt/silcdh.h
2778 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2782 * Removed silc_client_packet_send_flush from the client library
2783 as it is not needed. Affected file lib/silcclient/client.[ch].
2785 * Added printing of message of unresolved authentication method
2786 to the Irssi SILC client. Added it to the module formats.
2787 Removed the same message from the client library.
2789 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Added new distribution feature, DISTLABEL. Every distribution
2792 can define own preprocessor label that can be used in the
2793 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2794 file distributions, acconfig.h.pre and prepare.
2796 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2798 * Added Makefile.defines_int to include the actual definitions
2799 for Makefile.defines.in. Tested the new distribution system,
2800 created distributions and tested installation.
2802 * Added AWAY message printing to the Irssi SILC client. Added
2803 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2805 * Added SCONNECT command to call the SILC's CONNECT command.
2806 Cannot use CONNECT directly since Irssi uses that internally.
2807 Affected file irssi/src/silc/core/silc-servers.c.
2809 Added ACTION local command. It is same as ME command but takes
2810 the channel as mandatory argument.
2812 Rewrote some of the Irssi's help files to suite for SILC
2815 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2817 * Added Makefile.defines[.in] that should for now on be included
2818 in all Makefile.am file in the source tree. That file includes
2819 all common compilation definitions for SILC source tree.
2821 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Minor changes to the ./prepare script to change the package
2824 name according the distribution name to the configure.in.
2826 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * Created new distribution system. Added file `distributions'
2829 that defines all the distributions that can be created out of
2830 the SILC source tree. The ./prepare script now reads that
2831 file to determine how to prepare the distributions. The
2832 first argument to the ./prepare is the name of the distribution
2833 and second is the version of the distribution. If given
2834 without arguments it creates the default (toolkit) distribution
2835 with the default version (defined in ./prepare).
2837 All Makefile.am files that are subject to the distributions
2838 are now named as Makefile.am.pre. These are ./Makefile.am
2839 and lib/Makefile.am. Others may be changed later.
2841 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Added invite list, ban list, some key management and connection
2844 error message printing to module formats in the Irssi SILC client.
2846 * Added new silc_client_set_away_message to set the away message
2847 that is back to the person who sent private message. The
2848 affected file lib/silcclient/silcapi.h and the
2849 lib/silcclient/client_prvmsg.c.
2851 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2853 * Fixed the private message sending in the Irssi SILC client,
2854 added local command KEY to the Irssi SILC client.
2856 Added key management and key agreement message formats to the
2857 irssi/src/fe-common/silc/module-formats.[ch].
2859 Added USERS (alias WHO) printing, server/router operator
2860 indication and LIST command printing to the module formats.
2862 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Fixed channel joining notify handling, cumode notify handling
2865 from Irssi SILC client.
2867 * Added SILC specific module-formats to the Irssi SILC client so
2868 that SILC specific message hilighting, colors etc is possible.
2869 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2871 Added channel mode, channel user mode, actions, notices,
2872 whois and whowas printing to the the module-formats.c.
2874 * Fixed a bug in channel deletion in the server. The channel
2875 is not left to the cache even if the channel founder auth mode
2876 is set when there are no users anymore on the channel. Affected
2877 file silcd/server.c.
2879 * The silc_net_localhost now resolves the entire hostname including
2880 the domain name. Affected file lib/silcutil/silcnet.c.
2882 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Changed the ask_passphrase client operation to be ascynchronous.
2885 It has now a completion callback and a context that the
2886 application must call after it has got the passphrase from
2887 the user. Affected files lib/silcclient/silcapi.h,
2888 lib/silcclient/protocol.c, lib/silcclient/command.c and
2891 Added SilcAskPassphrase callback that the application calls
2892 to deliver the passphrase to the library.
2894 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2895 The public key verification and especially a certificate
2896 verification is asynchronous procedure.
2898 Added new SILC_SKE_STATUS_PENDING status to indicate the
2899 request is pending and a callback will be called to finalize
2902 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2903 indicate that remote end did not send its public key (or
2904 certificate), even though we require it. Added check for this
2905 condition in the SKE. This was a security bug, now fixed.
2907 Defined new SilcSKEVerifyCbCompletion callback that is called
2908 when the verification process is completed.
2910 The affected files lib/silcske/silcske_status.h and
2911 lib/silcske/silcske.[ch].
2913 * Changed the verify_public_key client operation to be async
2914 as well. Defined SilcVerifyPublicKey callback that is used to
2915 indicate the success of the public key verification process.
2917 Changed the server and client to use the new async client
2920 * Changed the Irssi SILC client's internal scheduler to be called
2921 twice as many times as it used to be. As a result the client
2922 should be a bit faster now. Affected file is
2923 irssi/src/silc/core/silc-core.c.
2925 * Added support to Irssi SILC client of asynchronous public key
2926 verification and passphrase inquiry. Affected file is
2927 irssi/src/silc/core/silc-core.c.
2929 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2931 * Do not say "You have left channel %s" in client library.
2932 Moved it to the application. Affected files are
2933 lib/silcclient/command.c and silc/client_ops.c.
2935 * Fixed silc_client_get_clients. Command context was not
2936 duplicated and was freed memory in the callback. Affected
2937 file lib/silcclient/idlist.c.
2939 * Do not say "you are now talking..." on JOIN command in the
2940 client library. The appliation must handle it.
2942 * Do not say ".. changed topic to" in command reply in the
2943 client libary. The application must handle it.
2945 * Fixed TOPIC command sending in the client library.
2947 * Fixed a memory leak in silc_client_command_free in the file
2948 lib/silcclient/command.c.
2950 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2952 * Imported a modified version of Irssi client to the source tree.
2953 The Irssi will be used to create a new client called
2954 Irssi SILC. Imported to irssi/.
2956 Added silc_core_init_finish function to the Irssi. Affected
2957 file irssi/configure.in.
2959 A lot changes in the Makefile.ams around the irssi tree.
2961 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Do not rehash if the new size is same as the old size of the
2964 hash table, in the silc_hash_table_rehash*. The affected file
2965 lib/silcutil/silchashtable.c.
2967 * Replaced hash_table_del_by_context calls from the server
2968 (when channel->user_list and client->channels) to the
2969 hash_table_del as it is sufficient and faster.
2971 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2973 * Added silc_hash_table_list, silc_hash_table_get and the
2974 SilcHashTableList structure to provide an alternative way to
2975 traverse the hash table. The affected files are
2976 lib/silcutil/silchashtable.[ch].
2978 * Changed the server's idlist routines to use the hash table
2979 routines to optimize the code.
2981 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * Replaced the client entry's `channel' list and channel entry's
2984 `user_list' list to hash tables for optimized lookup. Changed
2985 the code to use the hash table interface around the code.
2986 Affected file lib/silcd/idlist.[ch].
2988 * Added `auto_rehash' boolean argument to the function
2989 silc_hash_table_alloc to indicate whether the hash table should
2990 auto-rehash when it thinks is appropriate time. It will
2991 increase the hash table size if the there is twice as much
2992 entries in the table than the size of the table, and will
2993 decrease the size if there are twice as less entries than
2994 the size of the table.
2996 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3000 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * silc_idcache_purge_by_context deletes the entry now by context
3003 as it is supposed to do. Affected file lib/silccore/idcache.c.
3005 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3006 client is not anymore valid (WHOWAS givens the info) and not
3007 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3009 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Removed the `data' and `data_len' arguments from the ID Cache
3012 interfaces and added `name' argument. ID Cache does not handle
3013 anymore the binary data only a names associated with given ID.
3015 * When hashing a Client ID with silc_hash_id the entire ID is
3016 not hashed anymore, instead only the hash of the Client ID is
3017 hashed. This way we can access the Client ID from the cache
3018 with Client ID but with the hash of the ID (which is a hash of
3019 the nickname) as well without any difference in performance.
3021 Added also silc_idcache_find_by_id_one_ext to do one on one
3022 searching when we have the actual ID. Added also function
3023 silc_hash_client_id_compare. The affected files are
3024 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3026 * When hashing the name associated with a ID it is always done
3027 in lowercase. This way we can access the cache without worrying
3028 about case-sensitivity, even though, for example nicknames are
3031 * Fixed a bug in server with channel message sending. It put
3032 wrong ID type as destination ID. The affected file
3033 silcd/packet_send.c.
3035 * silc_idcache_del_by_context now deletes from all hash tables
3036 by context. Affected file lib/silccore/idcache.c.
3038 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3040 * Changed the client library to use the new ID Cache interface.
3041 Changes around the source tree.
3043 * Added silc_hash_table_rehash_ext to rehash with specific
3044 hash function. Affected file lib/silcutil/silchashtable.[ch].
3046 * Added silc_hash_string_compare to compare two strings in the
3047 hash table. Affected file lib/silcutil/silcutil.[ch].
3049 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * Added new function silc_idcache_del_by_context into the
3052 lib/silccore/idcache.[ch].
3054 * Changed the server's ID list routines to use the new ID Cache
3055 interface. Changes around the source tree.
3057 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3059 * Added silc_hash_table_del[_by_context]_ext functions in to the
3060 lib/silcutil/silchashtable.[ch].
3062 Removed silc_hash_table_find_all* routines and added new
3063 silc_hash_table_find_foreach to replace them.
3065 Added silc_hash_table_replace_ext function as extended
3066 replacing function. Separated the simple hash table interface
3067 from the extended hash table interface in the file
3068 lib/silcutil/silchashtable.h.
3070 * Fixed minor bugs and changed it to use some of the new
3071 hash table functions in lib/silccore/idcache.c
3073 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Added new function silc_hash_table_find_all to return all keys
3076 in the hash table by the specified key. As the hash table is
3077 collision resistant it also makes it possible to have several
3078 duplicate keys in the hash table. This function may be used to
3079 find all of the keys from the hash.
3081 Added user_context arguments to the SilcHashFunction,
3082 SilcHashCompare and SilcHashDestructor to deliver user specified
3085 Added new fuctions silc_hash_table_find[_all]_ext to do
3086 extended lookup with specified hash and compare functions and
3087 specified user contexts.
3089 Added new function silc_hash_table_add_ext to add the key
3090 with specified hash function and user context.
3092 Added new function silc_hash_table_foreach to traverse all
3093 entrys in the hash table. Added SilcHashForeach callback
3096 Added new function silc_hash_table_del_by_context to delete
3097 the entry only if the context associated with the key matches.
3099 Affected files are lib/silcutil/silchashtable.[ch].
3101 * Removed silc_hash_[server/client/channel]_id and added just
3102 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3103 silc_hash_id_compare to compare two ID's using as the hash table
3104 comparison function. Added also silc_hash_data to hash
3105 binary data and silc_hash_data_compare to compare it.
3107 * Removed silc_idlist_find_client_by_hash as it is not needed
3108 anymore. Affected file silcd/idlist.[ch].
3110 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3111 to use internally the SilcHashTable. The new ID Cache is a lot
3112 faster than the old one. Some of the ID Cache interface was also
3113 rewritten and obsolete and stupid functions were removed.
3115 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Added entry_count field to the SilcHashTable to keep the number
3118 of the entries in the table. Implemented the function
3119 silc_hash_table_rehash. Added new function
3120 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3122 Fixed a minor bug in silc_hash_table_free.
3124 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3125 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3126 into the lib/silcutil/silcutil.[ch].
3128 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3130 * Implemented a collision resistant hash table into the
3131 lib/silcutil/silchashtable[ch]. See the header and the source
3132 for the SilcHashTable API.
3134 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3136 * Merged dotconf version 1.0.2 into lib/dotconf.
3138 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Do not compile anything in lib/silcsim/* if the SIM support
3141 is not enabled. The tree should now compile without problems
3144 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Compiled the SILC under cygwin. Compiled and tested briefly
3147 without problems. More tests needed. The SIMs didn't compile
3150 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3152 * Fixed possible crash in silc_get_username in the
3153 lib/silcutil/silcutil.c.
3155 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Fixed a va_arg in silc/client_ops.c.
3159 * Oops, RC5 routines were named AES and caused some problems
3160 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3162 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Added new SilcIDIP structure into the lib/silccore/id.h and
3165 replaced the old `ip' fields from all SILC ID's to that type.
3166 This is a step towards IPv6 support.
3168 The silc_id_get_len takes now the ID as an extra argument.
3169 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3170 both IPv4 and IPv6 based ID's.
3172 The affected files are lib/silccore/id.[ch] and other files
3173 around the tree using these routines.
3175 * Removed the ID length arguments in server from various
3176 silc_server_send_notify_* routines -> they are not needed
3179 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3181 * Fixed memory leak in silc_encode_pem_file in the file
3182 lib/silcutil/silcutil.c.
3184 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Check minor version as well in the SKE. Affected files are
3187 silcd/protocol.c and lib/silcclient/protocol.c.
3189 * Added --identifier option to the server so that an identifier
3190 can be when creating the public key for the server. Affected
3191 file is silcd/silcd.c.
3193 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3194 lib/silccrypt/silcpkcs.c.
3196 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3198 * Register default ciphers and stuff when using -C option with
3199 the server. Affected file sildc/silcd.c.
3201 * Put back the servers public key filename format, it is better
3202 than the new one. For now, the client keys are saved with the
3203 new filename format. The affected file silc/client_ops.c.
3205 * Implemented the Cipher API for the rest of the ciphers that
3206 did not implement it or implemented it the wrong way.
3208 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Register default ciphers and stuff when using the -S option
3211 in the client. Affected file silc/silc.c. Same also when
3212 creating new key pair with -C option.
3214 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3216 * Fixed the silc_verify_public_key client operation function to
3217 save the public keys differently. The fingerprint is now
3218 used as filename and not the hostname. This way also the
3219 client keys are saved uniquely and not with hostnames. The
3220 affected file is silc/client_ops.c.
3222 * Trimmed the silc_hash_fingerprint function to remove extra
3223 whitespaces from the end of the fingerprint. The affected
3224 file is lib/silccrypt/silchash.c.
3228 * Added silc_cipher_register_default function to register all
3229 default ciphers. It can be used when configuration files
3230 does not exist and the application does not want any specific
3231 ciphers in any specific order.
3233 The SilcDList is now used as silc_cipher_list dynamically
3234 allocated cipher list. Removed the static list all together
3235 and now all ciphers must be allocated to the dynamic list.
3236 The silc_cipher_alloc routine was changed to check only the
3239 All silc_cipher_* routines that used to return int returns
3242 The affected files lib/silccrypt/silccrypt.[ch].
3244 * The same thing was done to silc_hash_* as for silc_cipher_*
3245 routines. Affected files lib/silccrypt/silchash.[ch].
3247 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3248 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3249 Added also silc_pkcs_[un]register[_default] functions.
3250 Removed the data_context from the PKCS API.
3252 * Added silc_hmac_register_default function to register default
3253 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3254 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3255 to unregister all hmacs at once.
3257 * Register the default ciphers, hash functions, PKCSs and HMACs
3258 if client's configuration file does not exist. The affected
3261 * The client did not load the hash functions from the SIM
3262 modules at all. Added support for this. Affected file is
3263 silc/clientconfig.c.
3265 * When decoding public key with silc_pkcs_public_key_decode, check
3266 the supported algorithm only if PKCS are registered. Affected
3267 file lib/silccrypt/silcpkcs.c. The same was done with the
3268 silc_pkcs_private_key_decode.
3270 * Fixed the SILC List routines to keep the list always in order.
3271 It used to change the list's order when traversing the list but
3272 not it preserves the order. Affected file lib/trq/silclist.h.
3274 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * Added the client library to use the SilcSocketConnection's
3277 reference counter (by silc_socket_dup) to prevent the bug that
3278 the socket object may be freed underneath async operation.
3280 * The name resolv library checking fixes in the configure.in.pre.
3283 * Created new version of the protocol drafts for future
3284 development. The -03 drafts are the ones that will be changed
3285 in the trunk now and the -02 will remain as they are.
3287 * Send list of CUMODE notifys to the router when announcing
3288 the channel users to the router. Affected file silcd/server.c.
3289 If the router receiving channel founder CUMODE for a channel
3290 that already has channel founder it will send CUMODE notify
3291 to the sender to remove the channel founder rights from the
3292 announced client. Affected file silcd/packet_receive.c.
3294 * The CUMODE notify may now use Server ID as well as the entity
3295 who changes the mode. Updated protocool specs.
3297 * Updated INSTALL and README files.
3299 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * New web pages in the http://silc.pspt.fi. The pages was
3306 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3308 * Implemented the [DenyConnectin] config section in the server.
3309 Added silc_server_config_denied_conn to check whether incoming
3310 connection is denied. Affected file silcd/serverconfig.[ch].
3312 * Do not check the ports when checking the incoming configuration
3313 data if the port is 0, meaning any. Affected file is
3314 silcd/serverconfig.c.
3316 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Fixed buffer overflow in silc_string_compare in the file
3319 lib/silcutil/silcutil.c.
3321 * Fixed double free in silc_server_command_leave in the file
3324 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Fixed the version checking in the server. Affected file is
3329 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3331 * Fixed the configuration data fetching when accepting new
3332 connections in the server. Affected file silcd/server.c.
3334 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Added `sender_entry' argument to the function
3337 silc_server_packet_relay_to_channel so that we can check
3338 whether some destination actually belongs to the same route
3339 the sender belongs (ie, we must not resend the packet to the
3340 sender). Affected file silcd/packet_send.[ch].
3342 * Added `servername' field to the SilcClientEntry in the server
3343 to hold the name of the server where client is from. Affected
3344 file is silcd/idlist.h.
3346 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Moved the channel message encrypting in the router betwen
3349 router connections from silc_server_channel_message to the
3350 silc_server_packet_relay_to_channel since we want to check
3351 whether we have anybody channel before encrypting anything.
3352 Affected files silcd/packet_[receive/send].c.
3354 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3356 * Fixed the [AdminConnection] server config section to support
3357 multiple entries. Affected file silcd/serverconfig.c.
3359 * Added support into the server to check the validity of the
3360 incoming connection before executing any KE or authentication
3363 * The connection configuration is now saved to the KE and
3364 connection auth protocol contexts and not fetched anymore in
3365 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3367 * The local hosts listenning address and port is also resolved
3368 now when starting the server. We want to have the socket object
3369 to include the real address and port for the listener. Added
3370 new function silc_net_check_local_by_sock into the files
3371 lib/silcutil/silcnet.[ch].
3373 * Fixed a broadcast bug in server -> do not broadcast if we
3376 * Fixed a routing bug. Do not route broadcast packets ever.
3377 Broadcast packets must be processed always and not routed since
3378 they may be destined to some other host than yourself and thus
3379 would get routed without no good reason. Affected file is
3382 * Added function silc_server_config_is_primary_route to check
3383 whether primary router connection has been configured (a router
3384 configuration that we are initiating). If there is not, we
3385 will assume that there is only two routers in the SILC network
3386 and we will use the incoming router connection as our primary
3387 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3389 * Changed the order of the broadcasting. Broadcast _after_ the
3390 packet has been processed not before. Affected file is
3393 * Fixed a [ClientConnection] parsing bug. The port was never
3394 parsed correctly thus resulting to port 0. Affected file
3395 silcd/serverconfig.c.
3397 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3398 argument and did not set the broadcast packet flag. Affected
3399 file silcd/packet_send.c. Fixed same bug in the function
3400 silc_server_send_notify as well.
3402 * If we receive NEW_ID packet for our own ID in the server, ignore
3405 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Removed the nickname from the Private Message Payload.
3410 Updated the code and the protocol specs.
3412 * Updated protocol specs for submitting to the IETF.
3414 * Tweaked the Random Number Generator a bit. Affected file
3415 lib/silccrypt/silcrng.c. Exported a new function
3416 silc_rng_[global]_add_noise which can be used to add more
3419 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Do not parse packets with different timeout when protocol
3422 is active -> may cause problem with rekey. Affected file
3425 * When server receives signoff notify it must not create
3426 new channel key if the client is on any channels since the
3427 sender of the signoff notify will create it.
3429 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Added printing of error messages during SKE protocol from the
3432 failure packet sent by server during SKE. Affected file
3435 * Removed the client's failure_callback handling with timeout
3436 and handle it immediately when received.
3438 * The SKE library returned wrong type in SUCCESS and FAILURE
3439 packets. They must be 32 bit MSB not 16 bit MSB.
3441 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Ok, rewrote the logic of the re-key and now it seems to work.
3444 I tested it on high traffic with frequent re-keys without
3445 problems. Added hmac_receive (and renamed hmac to hmac_send)
3446 in SilcClientConnection in lib/silcclient/client.h and
3447 in SilcIDListData in silcd/idlist.h. Also, removed the
3448 SilcPacketParserContext's cipher and hmac fields as they are
3449 not needed anymore and actually caused some problems when
3450 the ciphers and hmac's changed underneath the packet parser.
3452 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * If re-key protocol is active then process the incoming packets
3455 synchronously since we must assure that icoming packets encrypted
3456 with the old key is processed before the new keys is set to
3457 use. This is true other packets than for REKEY packets.
3458 Affected file silcd/server.c. The same was done to client library
3459 as well, affected file lib/silcclient/client.c.
3461 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Fixed bug in client and server to accept the force send if
3464 the packet is send from silc_[server/client]_packet_process
3465 function. Otherwise the packets are never delivered, oops.
3467 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * Disable force sending of packets when REKEY protocol is active.
3470 We must assure that no packet is sent directly when rekey is
3471 performed. All packets must be sent through packet queue.
3472 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3473 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3474 function is silc_[server/client]_packet_send_real to check
3477 * Replaced the SIM paths from example config files to
3478 /usr/local/modules. Also, make install creates now
3479 /usr/local/silc/logs directory to hold all the SILC server
3482 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Made the configure.in.pre work on Solaris. Patch by salo.
3486 * Made all ciphers compatible with non-x86 machines. Defined
3487 CBC mode macros into lib/silccrypt/ciphers_def.h.
3489 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Fixed the make install.
3493 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * When MAC computation fails the silc_packet_decrypt returned 0
3496 even though it was supposed to return -1. Fixed this. The
3497 affected file is lib/silccore/silcpacket.c.
3499 * Do not replace the config files in /etc/silc (in make install)
3500 if they already exist. Affected file ./Makefile.am.
3502 * Do not send re-key packets immediately but through packet queue.
3503 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3505 * Changed silc_net_check_host_by_sock to return FALSE if the
3506 IP/DNS could not be resolved. Though, it returns the IP address
3507 now even if it could not resolve it (but returns also FALSE).
3508 Affected file lib/silcutil/silcnet.[ch].
3510 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3512 * Added silc_pkcs_decode_identifier to decode the public key's
3513 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3514 Added also silc_pkcs_free_identifier. Added also new context
3515 SilcPublicKeyIdentifier.
3517 * Added -S option to the silc client. It is used to dump the
3518 contents of the specified public key file.
3520 * Changed the PKCS api to return the public key length when
3521 setting the public key.
3523 * Fixed a fatal bug in the public and private key file loading.
3524 Affected file lib/silccrypt/silcpkcs.c.
3526 * Execute the packet parsing for client with zero (0) timeout
3527 if the protocol is active. Affected file silcd/server.c.
3529 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Made the key generation options to the silcd program. Added
3532 -C option, equivalent to client's option.
3534 * Added new [ServerKeys] config section to the server. It
3535 configures the server's public and private key.
3537 * Defined generic Public Key Payload into the protocol
3538 specification to send specific type of public keys and
3541 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3542 public key or certificate.
3544 * Implemented the GETKEY command to the server and to the
3545 client library and on user interface.
3547 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3549 * Made preliminary `make install' work.
3551 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3553 * Added SilcServerRekey context into silcd/idlist.h.
3555 * Added the PFS support as defined in the specification to the
3556 SKE protocol. Affected files lib/silcske/*.c.
3558 * Added `ske_group' field to the SilcServerRekey context to hold
3559 the number of the SKE group that is used with PFS in re-key.
3560 Affected file silcd/idlist.h.
3562 * Added PFS re-key support to the server. Affected file is
3565 * Added silc_protocol_cancel to cancel execution of the next
3566 state of the protocol. Affected file is
3567 lib/silccore/silcprotocol.[ch].
3569 * Added the re-key support with and without PFS to the client
3570 library. Re-key is performed once in an hour, by default.
3572 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3573 Added silc_client_rekey_callback and silc_client_rekey_final.
3574 Affected files are lib/silcclient/protocol.[ch] and
3575 lib/silcclient/client.[ch].
3577 * Removed the `hmac_key' and `hmac_key_len' fields from the
3578 SilcClientConnection structure; not needed. Affected file is
3579 lib/silcclient/client.h.
3583 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Do not ask whether user wants to use the negotiated private key
3586 for private messages, just use it. Affected file is
3587 silc/local_command.c.
3589 * Added `send_enc_key' and `enc_key_len' fields to the
3590 SilcIDListData structure since they are needed in the re-key
3591 phase. Affected file is silcd/idlist.[ch].
3593 * Implemented the simple re-key protocol into the server.
3594 Affected files silcd/server.c and silcd/protocol.[ch]. The
3595 re-key will be performed once in an hour, by default.
3597 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3598 Added silc_server_rekey, silc_server_rekey_callback and
3599 silc_server_rekey_final.
3601 * Removed Tunneled flag from the protocol. Updated the code
3602 and the specifications.
3604 * Adde `pfs' field to the SilcIDListData to indicate whether
3605 the PFS is to be performed in the re-key. Affected file is
3608 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3611 int64 of at least the xintXX size. If void * is less that 4
3612 bytes uint32 * will be used. Defined bool as boolean.
3614 * Changed _ALL_ unsigned long and unsigned int to uint32,
3615 unsgined short to uint16 in the source tree.
3617 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3618 not handle clients that has entry->data.registered == FALSE.
3619 They are not in the network anymore. Affected file is
3622 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Implemented the sending of the SERVER_SIGNOFF notify in the
3625 server. Affected file is silcd/server.c.
3627 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3628 Added also silc_notify_payload_encode_args into the
3629 lib/silccore/silcnotify.[ch].
3631 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3632 Affected file silcd/packet_receive.c.
3634 * Implemented the SERVER_SIGNOFF notify handling in the client
3635 library. Affected file lib/silcclient/client_notify.c. Also,
3636 implemnted the printing of the SERVER_SIGNOFF info to the
3637 application. Affected file silc/client_ops.c.
3639 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3640 if the deleting was successful. Affected file silcd/idlist.[ch].
3642 * Added support for public key authentication in the connection
3643 authentication protocol in the client library. Affected file
3644 lib/silcclient/protocol.c.
3646 * Changed the server's silc_idlist_get_clients_by_* interface
3647 to support already allocated array so that new entries may be
3648 added to pre-allocated array. Affected file silcd/idlist.[ch].
3649 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3650 and command replies.
3652 * All command reply functions in the server now calls the
3653 pending command callback even if error occured. This way the
3654 error will be delivered to the client as well. Affected files
3655 silcd/command.c and silcd/command_reply.c.
3657 * Fixed INFO command to return local server's info if no server
3658 was provided. Affected file lib/silcclient/command.c.
3660 * Removed RESTART command for good. Updated the code and the
3663 * Rewrote parts of the task system. It is a bit simpler now.
3664 Removed unsued task priorities. The affected files are
3665 lib/silcutil/silctask.[ch].
3667 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Moved the USERS printing from the library to the application.
3670 Affected files lib/silcclient/command.c and silc/client_ops.c.
3672 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Added channel key re-key support. The re-key is perfomed
3677 only by the router and is done once in an hour. Added `rekey'
3678 field to the SilcChannelEntry in the server. Affected files
3679 silcd/server.c and silcd/idlist.h.
3681 * Added silc_task_unregister_by_context into the file
3682 lib/silcutil/silctask.[ch].
3684 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Added SILC_UMODE_GONE mode to indicate when the client is not
3687 present in the SILC network. Added also support to the local
3688 command AWAY that will set this mode. Added support of showing
3689 "xxx is gone" in WHOIS command. The USERS command shows the
3690 gone status as well.
3692 * Fixed setting server and router operator privileges in the
3693 server's UMODE command. Affected file silcd/command.c.
3695 * Merged the SKE KE1 and KE2 payloads into one payload. The
3696 new KE payload is equivalent to the old KE2 payload.
3698 Cleaned up the SKE Start Payload parsing. It now uses the
3699 simple buffer unformatting to do the parsing. A lot faster
3702 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3703 to the SKE that is used to indicate whether both of the SKE
3704 parties should perform authentication. By default only the
3705 responder performs authentication. By setting this flag also
3706 the initiator must do authentication. By default it is unset
3707 since in normal SKE case, client to server connection, only
3708 the responder should do authentication. When doing SKE between
3709 two clients both should perform authentication. Updated the
3710 code and the protocol specs.
3712 * A little fix to IDENTIFY command in the server. Search the
3713 client first by hash not nickname. Affected file is
3716 * Fixed the silc_client_close_connection to support closing
3717 the client to client connections wihtout deleting too much
3718 data. Affected file lib/silcclient/client.c.
3720 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3721 are received if protocol used to be active but is not anymore
3722 the application would crash due to NULL pointer dereference.
3723 Affected files silcd/server.c and lib/silcclient/client.c.
3725 * Added `hash' field to the SilcClientConnection to include
3726 the hash function negotiated in the SKE protocol.
3728 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3729 to set the channel founder authentication data. A client can
3730 claim the founder rights later by providing the authentication
3731 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3732 This way the channel founder can regain the channel founder
3733 privileges even it is left the channel. This works only on
3734 local server and the client must be connected to the same
3735 server to be able to regain the founder rights. Updated the
3736 protocol specs accordingly.
3738 Added support to the CMODE command in the client to set the
3739 founder auth data. Read the README to see how to set it.
3741 Added support to the CUMODE command to claim the founder
3742 rights. Read the README to see how to do it.
3744 Added support for the founder authentication to the Channel
3745 Entry in the server. Affected file silcd/idlist.h.
3747 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3748 server's CMODE command. Affected file silcd/command.c.
3750 * Added the following new functions into lib/silccore/silcauth.[ch]:
3751 silc_auth_get_method and silc_auth_get_data.
3753 * The server now saves the remote hosts public key to the
3754 SilcIDListData pointer. Affected file silcd/protocol.c.
3756 * The normal server now does not remove the channel entry from
3757 the cache if the founder authentication data is set. It used
3758 to remove it if the founder was the last one on the channel on
3759 the server and left the channel. The auth data is saved and
3760 if the channel is re-joined later the old entry is used with
3761 the old auth data. Affected files silcd/command_reply.c and
3764 * Removed the `pkcs' field from the SilcIDListData structure
3765 in the server; it is not used. Affected file silcd/idlist.h.
3767 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Fixed packet processing on slow links. Partial packets were
3770 never re-processed because the incoming data buffer was cleared
3771 by the application. Application must not directly clear the
3772 sock->inbuf, the packet processing routines handle it. Fixed
3773 this in client library and in server.
3775 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Fixed the WHOIS and IDENTIFY send reply function to really
3778 check whether to send list or just one entry. Affected file
3781 * Cleaned up the LEAVE command's channel key distribution. The
3782 affected file silcd/command.c.
3784 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3785 can enforce the channel mode as well. In that case the ID
3786 includes the ID of the server. The code now enforces the
3787 mode change if the router have different mode than the server.
3789 * The notify client operation with CMODE_CHANGE notify can now
3790 return NULL client_entry pointer if the CMODE was not changed
3791 by client. Application must check for this.
3793 * Added <Server ID> argument to INFO command to support server
3794 info fetching by Server ID.
3796 * Added silc_server_announce_get_channel_users to get assembled
3797 packets of channel users of the specified channel. Affected
3798 file silcd/server.[ch].
3800 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3801 was freed underneath the ID Cache.
3803 * Re-announce clients when the server received CHANNEL_CHANGE
3804 notify from the router. Affected file silcd/packet_send.c.
3806 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3808 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3809 crashed since it did not handle the fact that there is no cipher
3810 called "3" and didn't check the error condition. Now fixed.
3812 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3813 flag. It can be used to send message requests.
3815 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Implemented the RESTART command in the client.
3819 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3820 notice type messages. Added notice printing to the user
3823 * The channel keys are not re-generated if the channel's mode
3824 is PRIVKEY, ie private key on the channel exists. Affected
3825 files silcd/server.c and silcd/command.c.
3827 * Fixed a little bug in channel message delivery when channel
3828 private keys are set in the server. Affected file is
3829 silcd/packet_send.c.
3831 * Changed the setting on channel->on_channel = TRUE from the
3832 silc_client_save_channel_key to the JOIN command reply. The
3833 key payload is not received if the private channel key is set.
3834 Affected file lib/silcclient/command_reply.c and the
3835 lib/silcclient/client_channel.c.
3837 * When the CMODE_CHANGE notify is sent and the channel private
3838 key mode is removed the channel key must be re-generated in
3839 other cells as well. Added this support for the router in the
3840 silcd/packet_receive.c.
3842 * Added new local command NOTICE to send notice message on
3843 channel. Affected file silc/local_command.[ch].
3845 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Added new local command ME to the client. It is used to send
3848 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3849 some action. Affected file silc/local_command.[ch].
3851 * Changed channel_message and private_message client operations
3852 to deliver the message flags to the application. Added also
3853 the `flags' arguments to the silc_client_send_channel_message
3854 and silc_client_send_private_message functions. Affected file
3857 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Redefined the Private Message Payload to support private message
3860 keys and to support the new private message flags. Updated
3861 the protocol specs. Flags makes it possible to have for example
3862 CTCP style messages.
3864 * Added new type SilcPrivateMessagePayload and defined an API
3865 for it in the lib/silcclient/silcprivate.[ch].
3867 * Tested private message private keys successfully. Tested the
3868 private message key set, unset and list commands with the new
3871 * Redefined the Channel Message Payload to include the channel
3872 message flags (equal with private message flags) to support
3873 for example CTCP style messages.
3875 * Defined some of the message (for channel and private message)
3876 flags. Updated the protocol specs and added the flags to the
3877 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3879 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Added SilcKeyAgreementStatus type to the key agreement routines
3882 to indicate the current status and error if one occured.
3883 The status types are defined in the lib/silcclient/silcapi.h.
3885 * Added new local command KEY that is used to set and unset private
3886 keys for channels, set and unset private keys for private messages
3887 with remote clients and to send key agreement requests and
3888 negotiate the key agreement protocol with remote client. The
3889 key agreement is supported only to negotiate private message keys,
3890 it currently cannot be used to negotiate private keys for channels,
3891 as it is not convenient for that purpose.
3893 * Fixed a minor pending callback setting bug in the function
3894 silc_client_get_client_by_id_resolve, now the function works.
3895 Affected file lib/silcclient/idlist.c.
3897 * Added function silc_net_get_local_port to get local bound
3898 port by socket. Added to lib/silcutil/silcnet.[ch].
3900 * Added `sockets' and `sockets_count' fields to the SilcClient
3901 object. They hold the sockets of the listenning sockets in
3902 the client. Listenning sockets may be for example the key
3903 agreement server. Affected file lib/silcclient/client.[ch].
3904 Added functions the silc_client_add_socket and the
3905 silc_client_del_socket. They are exported to the application
3908 * Added ~./silc/clientkeys to support other client's public keys.
3910 * Renamed verify_server_key client operation to verify_public_key
3911 and added one argument to indicate the type of the connection
3912 (server, client etc.).
3914 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3916 * Added silc_server_connection_auth_request to handle the
3917 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3918 silcd/packet_receive.[ch].
3920 * Added silc_server_send_connection_auth_request into the
3921 silcd/packet_send.c to send the connection auth request packet.
3923 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3926 * Fixed the public key authentication in responder side in the
3927 server. The `auth_data' pointer includes the SilcPublicKey
3928 not the path to the public key. Affected file silcd/protocol.c.
3930 * Implemented the public key authentication in the initiator side
3931 in the server. Affected file silcd/protocol.c.
3933 * Removed the [RedirectClient] config section from the server
3934 configuration. Is not needed and I don't want to implement it.
3936 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Cleaned up the CMODE command in the server. It now works
3939 correctly and supports all the modes defined in the protocol.
3940 Affected file is silcd/command.c.
3942 * Added `hmac_name' field to the SilcChannelEntry in the server
3943 to hold the default HMAC of the channel. It can be set when
3944 creating the channel (with JOIN command). Affected files
3947 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3948 type to indicate the change of the current cipher and hmac
3949 on the channel. Client can safely ignore the <cipher> argument
3950 (if it chooses to do so) since the CHANNEL_KEY packet will
3951 force the channel key change anyway. The <hmac> argument is
3952 important since the client is responsible of setting the new
3953 HMAC and the hmac key into use.
3955 * Fixed the CMODE command in the client library as well.
3957 * Tested CMODE command in router environment successfully.
3959 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Show the version of the remote client (or server) when connecting
3962 to the server. It is logged to the log file. Affected file
3963 is silcd/protocol.c.
3965 * Fixed the KILLED notify handling in the client library. The
3966 client must be removed from all channels when receiving the
3969 Also, do not remove the client entry when giving the KILL
3970 command but when the KILLED notify is received.
3972 * Removed silc_idlist_find_client_by_nickname from the server.
3973 Not needed anymore. Affected files silcd/idlist.[ch].
3975 * Implemented the CHANNEL_CHANGE notify type handling to the
3976 server. Affected file silcd/server.c.
3980 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3982 * Added silc_server_send_notify_invite to send the INVITE
3983 notify between routers.
3985 * Implemented the INVITE command correctly to the server.
3987 * Implemented the INVITE notify type handling in the server.
3989 * Implemented the INVITE command to the client library and on the
3992 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Added function silc_server_get_client_resolve to find the
3995 client entry by ID from all ID lists and then resolve it
3996 (using WHOIS) if it cannot be found. Affected file is
3999 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Implemented the BAN command to the client library.
4003 * The JOIN command in the server now checks the invite list
4006 * Changed the silc_command_reply_payload_encode_va and the
4007 silc_command_payload_encode_va to support that if argument is
4008 NULL it ignores and checks the next argument. Affected file
4009 lib/silccore/silccommand.c.
4011 * Added silc_server_send_notify_ban to send the BAN notify
4012 type between routers.
4014 * Chaned the silc_notify_payload_encode to support that if
4015 argument is NULL it ignores and checks the next argument.
4016 Affected file lib/silccore/silcnotify.c.
4018 * Tested ban lists in router environment successfully.
4020 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Implemented BAN command to the server, in silcd/command.[ch].
4024 * Removed the BAN and INVITE_LIST modes from the CMODE command
4027 * Added function silc_string_match to regex match two strings.
4028 Affected files lib/silcutil/silcutil.[ch].
4030 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Redefined parts of the SilcChannelEntry in the server to support
4033 the new ban and invite lists.
4035 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Redefined the INVITE command. The same command can be used to
4038 invite individuals to the channel but also to manage the invite
4039 list of the channel (to add to and remove from the invite list).
4040 Updated the protocol specs.
4042 * Added new command SILC_COMMAND_BAN that can be used to manage
4043 the ban list of the channel. Updated the protocol specs.
4045 * Removed the channel modes: the SILC_CMODE_BAN and the
4046 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4047 in the CMODE command. The equivalent features are now available
4048 using INVITE and BAN commands. Updated the protocol specs.
4050 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4051 in the network about change in the current ban list. The notify
4052 type is not used by the client.
4054 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4055 support the invite lists.
4057 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4059 * Added new function silc_string_regexify that converts string
4060 including wildcard characters into regex string that can
4061 be used by the GNU regex library. Added into the file
4062 lib/silcutil/silcutil.[ch].
4064 Added silc_string_regex_combine to combine to regex strings
4065 into one so that they can be used as one regex string by
4066 the GNU regex library. Added into the file
4067 lib/silcutil/silcutil.[ch].
4069 Added silc_string_regex_match to match two strings. It returns
4070 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4072 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4074 * Imported GNU regex to the soruce tree into lib/contrib.
4075 Fixed some compiler warning from the regex.c.
4077 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Fixed MOTD command in the server to work in router environment.
4081 * Fixed the MOTD command in the client library to support
4082 the server argument in the command.
4084 * Added `nickname_len' argument to the silc_idlist_add_client
4085 in the server, as the `nickname' argument may be binary data
4088 * Added silc_idlist_get_channels to return all channels from
4091 * Implemented LIST command to the server. Affected file is
4094 * Implemented the LIST command to the client library and on the
4097 * Added [<user count>] argument to the LIST command reply.
4098 With private channels the user count is not shown.
4100 * Updated TODO and README.
4102 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * The client entry's data.registered must be TRUE even with
4105 global client entry on global client list. The data.registered
4106 is used to check whether the client is anymore in the network,
4107 for example with WHOWAS command so it must be valid.
4109 * Fixed the WHOWAS command in the server. It now actually works
4110 in router environment. Added function into silcd/command_reply.c
4111 silc_server_command_reply_whowas_save.
4113 * Added silc_idlist_purge function to the silcd/idlist.c
4114 to periodically purge the ID Cache.
4116 * Fixed INFO command in the server. It works now in router
4117 environment. Added <server name> argument to the INFO command
4118 reply. Updated the protocol specs.
4120 * Fixed minor bug in silc_idcache_purge to not purge if the
4121 expire value is zero.
4123 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4124 they were buggy because of the WHOWAS information.
4126 * Fixed local command MSG to handle the async resolving of
4127 the remote client properly. It used to fail the first MSG.
4128 Affected file silc/local_command.c.
4130 * Added `data_len' field to SilcIDCache context.
4132 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4134 * Update TODO. Todo in commands in the server.
4136 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4139 used by routers as broadcast packet to inform other routers
4140 about the changed user mode.
4142 Implemented the notify handling in the server. Affected file is
4143 silcd/packet_receive.c. Added the function
4144 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4146 * Added new generic Channel Payload and deprecated the New Channel
4147 Payload. The New Channel Payload is now the generic Channel
4150 * Added new argument `mode' to the silc_server_send_new_channel
4151 as it is required in the Channel Payload now.
4153 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4154 and created a new and real SilChannelPayload to represent the
4155 new generic Channel Payload. Implemented the encode/decode
4156 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4158 * Added silc_server_get_client_channel_list to return the list
4159 of channels the client has joined for WHOIS command reply.
4160 Affected file silcd/server.[ch].
4162 * Implemented the channel list sending in the WHOIS command reply
4163 in server and in the client.
4165 Implemented the channel list displaying on the user interface
4166 as well. Affected file silc/client_ops.c.
4168 * Added silc_channel_payload_parse_list to parse list of Channel
4169 Payloads. It returns SilcDList list of SilcChannelPayloads.
4170 Client for example can use this function to parse the list of
4171 channels it receives in the WHOIS command reply. The caller
4172 must free the list by calling silc_channel_payload_list_free.
4173 Affected files lib/silccore/silcchannel.[ch].
4175 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Added one new argument <user mode> to the WHOIS command reply
4178 to return the mode of the user in SILC. Updated the protocol
4181 Implemented it to the server and client.
4183 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Fixed the mode printing on the user interface on joining.
4186 Affected file silc/client_ops.c.
4188 * Implemented the UMODE command and user modes in general to the
4189 client library and to the user interface.
4191 * Implemented the UMODE command to the server.
4193 * The server now sends UNKNOWN_COMMAND error status if client sends
4194 unknown command. Affected file silcd/command.c.
4196 * All server commands now handle the command identifier the right
4197 way when sending the command reply to the client. The client can
4198 use to identify the command replies with the identifier.
4200 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Added silc_server_get_client_route to resolve the route to
4203 the client indicated by the client ID. Affected file is
4206 * Added silc_server_relay_packet as general function to relay
4207 packet to arbitrary destination. This deprecates functions
4208 like _send_private_message_key, _relay_notify etc. Affected
4209 file is silcd/packet_send.[ch].
4211 Removed silc_server_send_key_agreement,
4212 silc_server_send_private_message_key and
4213 silc_server_packet_relay_notify functions from the file
4214 silcd/packet_send.[ch].
4218 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4219 server. Affected file silcd/packet_receive.[ch].
4221 * Implemented the KILL command to the client. Implemented the
4222 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4223 Affected files lib/silcclient/command[_reply].c and
4224 lib/silcclient/client_notify.c. Implemented the KILL notify
4225 printing in the user inteface.
4227 * Fixed a lot silc_parse_nick memory leaks from the client
4228 library in the file lib/silcclient/command.c.
4230 * Changed the silc_server_send_notify_on_channels's `sender'
4231 argument from SilcSocketConnection to SilcClientEntry to
4232 check the sender as entry and not as connection object and not
4233 to send to the client provided as argument. The affected file
4234 is silcd/packet_send.[ch].
4236 * The notify packets that are destined directly to the client used
4237 to not to be processed by the server. Now changed that and the
4238 server processes all notify packets. After relaying the packet
4239 to the client the notify packet is processed in the server.
4241 * The silc_server_free_client_data now checks whether there is
4242 pending outgoing traffic for the client and purges the data to
4243 the network before removing the client entry.
4245 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4248 an client is killed from the SILC Network. Updated the protocol
4251 Added new function silc_server_send_notify_killed to the
4252 silcd/packet_send.[ch].
4254 * Added function silc_server_packet_relay_notify to relay notify
4255 packets that are destined directly to a client. In this case
4256 the server does not process the notify packets but merely relays
4257 it to the client. Affected file silcd/packet_send.[ch].
4259 Added also silc_server_packet_process_relay_notify to check
4260 whereto relay the notify. Affected file is
4261 silcd/packet_receive.[ch].
4263 * Implemented the KILL command to the server.
4267 * Added the backup schema desgined last fall to the protocol
4268 specs for everyone to see. The specification is in the
4269 *-spec-xx.txt draft and the packet type definitions for the
4270 backup routers is in *-pp-xx.txt draft. Thusly, added also
4271 new packet type SILC_PACKET_CELL_ROUTERS.
4273 * A big security problem in the implementation discovered. The
4274 signoff of an client did not cause new channel key generation
4275 which it of course should've done. The channel keys must be
4276 always re-generated when client leaves (or signoffs) the channel.
4277 The silc_server_remove_from_channels funtion now handles
4278 the channel key re-generation.
4280 * Added `sender' argument to the silc_server_send_notify_on_channels
4281 to not to send the client provided as argument. Affected file
4282 silcd/packet_send.[ch].
4284 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Implemented OPER and SILCOPER commands into the server and
4289 * Added silc_auth_verify and silc_auth_verify_data to verify
4290 the authentication directly from the authentication payload.
4291 It supports verifying both passphrase and public key based
4292 authentication. Affected file lib/silccore/silcauth.[ch].
4294 * Added `hash' field to the SilcIDListData structure. It is the
4295 hash negotiated in the SKE protocol. Affected file is
4298 * Slight redesigning of the SilcAuthPayload handling routines.
4299 Do not send SilcPKCS but SilcPublicKey as argument.
4301 * Implemented the public key authentication support to the
4302 serverconfig. The public key is loaded from the provided path
4303 and saved as authentication data to void * pointer. Thus,
4304 changed the unsigned char *auth_data to void *auth_data;
4306 * Fixed SHUTDOWN command to send the reply before the server
4307 is shutdown. :) Affected file silcd/command.c.
4309 * Fixed fatal bug in CONNECT command. The hostname was invalid
4310 memory and server crashed. Affected file silcd/command.c.
4312 * Fixed fatal bug in CLOSE command. The server_entry became
4313 invalid but was referenced later in the command. Affected file
4316 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4318 * Fixed fatal bug in failure packet handling. Server ignored
4319 the failure and thus crashed when it came.
4323 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4326 that the command may be executed only once in (about) 2 seconds.
4327 The old SILC_CF_LAG flag is same but allows command bursts up
4328 to five before limiting.
4330 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4331 server code. Various commands now includes the CF_LAG_STRICT
4332 flag to disallow any kind of miss-use of the command.
4334 * Fixed the silc_buffer_unformat to not to allocate any data
4335 if the length of the data is zero. It used to allocate the
4336 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4338 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Changed the format of AdminConnection configuration section
4341 in the server. Added username of the admin to the format.
4342 Affected files silcd/serverconfig.[ch].
4344 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4345 to return admin configuration data by host, username and/or
4348 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4350 * Implemented WHOWAS command to the server. Added the functions:
4352 silc_server_command_whowas_parse,
4353 silc_server_command_whowas_send_reply,
4354 silc_server_command_whowas_from_client and
4355 silc_server_command_whowas_from_server
4357 * Added <Client ID> argument to the WHOWAS command reply. Updated
4358 the protocol specs accordingly.
4360 * Implemented WHOWAS command and command_reply to the client
4363 Implemented the WHOWAS printing on the user interface.
4365 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Added new argument to the WHOWAS command reply, the real name.
4368 It is an optional argument. Updated the protocol specs.
4370 * Added SilcIDCacheDestructor callback that is registered when
4371 the SilcIDCache is allocated. The callback is called when
4372 an cache entry in the ID Cache expires, or is purged from the
4373 cache. Added into lib/silccore/idcache.[ch].
4375 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4376 to destruct the client entries when the cache entry expires.
4377 Other ID Cache's in server and in the client library ignores
4380 * If the ID Cache entry's `expire' field is zero then the entry
4381 never expires. Added boolean `expire' argument to the
4382 silc_idcache_add function in the lib/silccore/idcache.[ch].
4383 If it is TRUE the default expiry value is used.
4385 * Added silc_server_free_client_data_timeout that is registered
4386 when client disconnects. By default for 5 minutes we preserve
4387 the client entry for history - for WHOWAS command.
4389 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Added support to the server to enforce that commands are not
4392 executed more than once in 2 seconds. If server receives
4393 commands from client more frequently, timeout is registered
4394 to process the commands. Affected file silcd/command.c.
4395 Added new function silc_server_command_process_timeout.
4397 * Changed NICK_NOTIFY handling in client library to check that
4398 if the client's nickname was changed, so there is no need to
4399 resolve anything from the server.
4401 * Removed error printing from the WHOIS and IDENTIFY commands.
4402 If error occurs then it is ignored silently in the client library.
4403 The application, however, may map the received error to
4404 human readable error string. The application currently maps
4405 the NO_SUCH_NICKNAME error to string.
4407 * Made the command status message public to the application. Moved
4408 them from lib/silcclient/command_reply.c to
4409 lib/silcclient/command_reply.h. The application can map the
4410 received command status to the string with the
4411 silc_client_command_status_message function.
4413 * Added check to the server to check that client's ID is same
4414 as the Source ID in the packet the client sent. They must
4417 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Added dist-bzip hook to the Makefile.am to make bzip2
4420 compressed distributions.
4422 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4424 * Server now enforces the maximum length for the nickname and
4425 the channel as protocol specification dictates. 128 bytes for
4426 nickname and 256 bytes for channel name.
4428 * Moved the WHOIS printing to the application. The client libary
4429 does not print out the WHOIS information anymore, the application
4430 must do it. Renamed silc_client_command_reply_whois_print to
4431 the silc_client_command_reply_whois_save.
4433 The client's idle time is also sent to the application now, and
4434 the idle is shown on screen.
4436 * Added silc_client_command_reply_identify_save to save the
4437 received IDENTIFY entries.
4439 * Do not check for channel private keys in message sending and
4440 reception if the channel does not have the PRIVKEY mode set.
4441 Affected file lib/silclient/client_channel.c.
4443 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4445 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4446 just surfaced after chaning the JOIN procedure.
4448 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Added silc_client_get_clients_by_list to get client entries
4451 from Client ID list, that is returned for example by JOIN
4452 and USERS command replies. The application should use this
4453 function for example when JOIN command reply is received to
4454 resolve the clients already on the channel (library does not
4455 do that anymore as USERS command reply is not used in the JOIN
4456 procedure anymore). Affected files lib/silcclient/silcapi.h and
4457 lib/silcclient/idlist.c.
4459 * JOIN command reply and USERS command reply returns now SilcBuffer
4460 pointers instead of unsigned char pointers when returning
4461 the client list and mode list.
4463 * Added <Client ID> argument to the JOIN command reply, mainly
4464 for the server to identify for which client the command was
4465 originally sent. Updated protocol specs accordingly.
4467 * Added SilcDlist private_key pointer to the SilcChannelEntry
4468 in the client to support the channel private keys. Affected
4469 file is lib/silcclient/idlist.h.
4471 * Added SilcChannelPrivateKey argument to the function
4472 silc_client_send_channel_message so that application can choose
4473 to use specific private ke if it wants to. If it is not provided,
4474 the normal channel key is used, unless private keys are set.
4475 In this case the first (key that was added first) is used
4476 as the encryption key.
4478 * Implemented the support for channel private key handling.
4479 Implemented the following functions:
4481 silc_client_add_channel_private_key,
4482 silc_client_del_channel_private_keys,
4483 silc_client_del_channel_private_key,
4484 silc_client_list_channel_private_keys and
4485 silc_client_free_channel_private_keys
4487 Affected file lib/silcclient/client_channel.c.
4489 * Added the support for the private keys in the channel message
4490 sending and encryption and in the message reception and
4491 decryption. Affected funtions are
4492 silc_client_send_channel_message and silc_client_channel_message.
4494 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4496 * Added SKE's key verify callback to the client library's
4497 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4499 * Removed the statement that server (or router) must send USERS
4500 command reply when joining to the channel so that the client
4501 knows who are on the channel. Instead, the client list and
4502 client's mode list is now sent in the JOIN command reply to the
4503 client who joined channel. This is better solution.
4505 * Added function silc_server_get_users_on_channel and function
4506 silc_server_save_users_on_channel to the silcd/server.[ch].
4508 * Removed function silc_server_command_send_users from the
4511 * Do not show topic on the client library anymore. The topic is
4512 sent in the command reply notify to the application and the
4513 application must show the topic now.
4515 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Added client searching by nickname hash into the IDENTIFY and
4518 WHOIS commands in the server as they were clearly missing from
4519 them. Affected file is silcd/command.c.
4521 * Fixed a bug in private message receiving in the client library.
4522 The remote ID was freed and it wasn't supposed, now it is
4525 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Minor fix to the channel payload; allocate the data area, as it
4528 needs to be of specific length.
4530 * If the key agreement port is zero then the operating
4531 system will define the bound port. Affected files are
4532 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4534 * Added new function silc_channel_payload_decrypt into the file
4535 lib/silccore/silcchannel.[ch].
4537 * Moved the channel message etc, check from silc_packet_decrypt
4538 to applications. The library calls now a generic
4539 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4540 when the packet is either normal or special. This was done to
4541 allow more wide range of checking that was not allowed when
4542 the code was in library. Now applications can do virtually any
4543 checks to the packet and return to the library the decision how
4544 the packet should be processed. Affected files are
4545 lib/silccore/silcpacket.[ch].
4547 Added silc_server_packet_decrypt_check to the server and
4548 silc_client_packet_decrypt_check to the client library.
4550 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4551 to send with specified source and destination information.
4553 * Channel message delivery between routers was broken after the
4554 channel key distribution was fixed earlier. The channel key
4555 was used be to distributed to other routers as well which is not
4556 allowed by the protocol. Now this is fixed and channel keys
4557 really are cell specific and the channel message delivery between
4558 routers comply with the protocol specification.
4560 * Fixed various commands in server to check also the global list
4561 for the channel entry and not just the local list. The affected
4562 file silcd/command.c.
4564 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Added assert()s to buffer formatting and unformatting routines
4567 to assert (if --enable-debug) when error occurs. Affected
4568 file: lib/silcutil/silcbuffmt.c.
4570 * Changed to auto-reconnect to check whether the remote host is
4571 router and register the re-connect timeout if it is. It used
4572 to check that whether we are normal server, but router must do
4573 auto-reconnect with another router as well. Affected file
4576 * Removed the [<key len>] option from CMODE command as the cipher
4577 name decides the key length, nowadays. See the defined ciphers
4578 from the protocol specification.
4580 * Added [<hmac>] option to the CMODE command to define the HMAC
4581 for the channel. Added SILC_CMODE_HMAC channel mode.
4583 * Added [<hmac>] option for the JOIN command so that user can
4584 select which HMAC is used to compute the MACs of the channel
4587 * Added Hmac field to the Channel Message Payload. The integrity
4588 of plaintext channel messages are now protected by computing
4589 MAC of the message and attaching the MAC to the payload. The
4590 MAC is encrypted. Now, it is clear that this causes some
4591 overhead to the size of the packet but rationale for this is that
4592 now the receiver can verify whether the channel message decrypted
4593 correctly and also when private keys are set for the channel the
4594 receiver can decrypt the packet with several keys and check from
4595 the MAC which key decrypted the message correctly.
4597 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4598 lib/silccrypt/silccipher.[ch].
4600 * Added silc_hash_len to return the digest length into the
4601 lib/silcrypt/silchash.[ch].
4603 * Rewrote parts of Silc Channel Payload interface in the
4604 lib/silccore/silcchannel.[ch]. The encode function now also
4605 encrypts the packet and parse function decrypts it.
4607 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * Fixed a minor formatting bug in the SKE's key material processing.
4610 It actually might have processed the keys wrong way resulting
4613 * Redefined the mandatory HMAC algorithms and added new algorithms.
4614 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4615 and hmac-md5 truncated to 96 bits. The mandatory is now
4616 hmac-sha1-96. Rest are optional (including the one that used
4617 to be mandatory). Rationale for this is that the truncated HMAC
4618 length is sufficient from security point of view and can actually
4619 make the attack against the HMAC harder. Also, the truncated
4620 HMAC causes less overhead to the packets. See the RFC2104 for
4623 * Added new [hmac] configuration section. The SKE used to use
4624 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4625 is of course wrong. The official names that must be proposed in
4626 the SKE are the ones defined in the protocol specification
4627 (hmac-sha1-96 for example). The user can configure any hmac
4628 using any hash function configured in the [hash] section. At
4629 least, the mandatory must be configured.
4631 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4633 * Added HMAC list to the SKE proposal list. It has now both
4634 hash algorithm list and HMAC list. This makes the protocol
4635 incompatible with previous versions. The SKE now seems to work
4636 the way it is supposed to work, for the first time actually.
4638 * Defined plain Hash algorithms to the protocol specification.
4641 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Implemented support for key agreement packets into the server.
4644 Added functions silc_server_key_agreement and
4645 silc_server_send_key_agreement. Other than these functions,
4646 server has nothing to do with this packet.
4648 * Added support for private message key packets into the server.
4649 Added functions silc_server_private_message_key and
4650 silc_server_send_private_message_key.
4654 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4655 called in the protocol's final callback instead in the END
4656 protocol state. This makes a little more sense and in the same
4657 time in client we can use the same protocol routines for normal
4658 key exchange and to key agreement packet handling as well.
4660 * Added to both client's and server's KE protocol context the
4661 SilcSKEKeyMaterial pointer to save the key material. We will
4662 bring the key material to the protocol's final callback by doing
4663 this. The final callback must free the key material.
4665 * Added SKE's packet_send callback into client's KE protocol
4666 context so that the caller can choose what packet sending function
4667 is used. This way we can use different packet sending when
4668 doing normal SKE when doing key agreement packet handling (in
4669 the key agreement packet handling we do not want to encrypt
4672 * Implemented the responder side of the key agreement routines
4673 in the client. The client can now bind to specified port and
4674 accept incoming key negotiation. The key material is passed
4675 to the application after the protocol is over.
4677 * Implemented the processing of incoming Key Agreement packet
4678 in the client. Added function silc_client_key_agreement to
4681 * Implemented the intiator side of the key agreement routines
4682 in the client. The client can now initiate key agreement with
4683 another remote client. The key material is passed to the
4684 application after the protocol is over.
4686 * Created client_keyagr.c to include all the key agreement
4689 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4690 SILC_TASK_CALLBACK except that it is not static.
4692 * Created client_notify.c and moved the Notify packet handling
4693 from the client.[ch] into that file.
4695 * Created client_prvmsg.c and moved all private message and
4696 private message key routines from the client.[ch] into that file.
4698 * Create client_channel.c and moved all channel message and
4699 channel private key routines from the client.[ch] into that file.
4701 * Changed silc_client_get_client_by_id_resolve to resolve with
4702 WHOIS command instead of IDENTIFY command, in the file
4703 lib/silclient/idlist.c.
4705 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * Implemented the SKE's responder side to the Client library.
4709 * When FAILURE is received to the protocol do not trust it
4710 blindly. Register a timeout to wait whether the remote closes
4711 the connection as it should do it, only after that process the
4712 actual failure. This was changed to both client and server.
4714 * Added client_internal.h to include some of the structures
4715 there instead of client.h in lib/silcclient/.
4717 * Added function silc_task_unregister_by_callback to unregister
4718 timeouts by the callback function.
4720 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4722 * Some "Incomplete WHOIS info" errors has been appearing on the
4723 log files. Took away the entry->userinfo check from WHOIS
4724 reply sending. The entry->userinfo is now " " if client did not
4725 provide one. I thought this was fixed earlier but something
4726 is wrong still. Let's see if the error still appears.
4728 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Fixed a minor bug in the login when the channel key is
4731 re-generated in the server. It used to generate the key in
4732 wrong order and thus caused problems in the channel traffic.
4734 * Fixed a minor bug in channel key distsribution after
4735 KICK command. The key was not sent to the router even though
4738 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Added silc_ske_process_key_material_data as generic routine
4741 to process any key material as the SILC protocol dictates. The
4742 function is used by the actual SKE library but can be used by
4743 applications as well. This relates to the private message keys
4744 and the channel private keys since they must be processed the
4745 same way the normal SILC session keys. The protocol dictates
4746 this. Affected files: lib/silcske/silcske.[ch].
4748 Added also silc_ske_free_key_material to free the
4749 SilcSKEKeyMaterial structure.
4751 * Defined silc_cipher_set_key function to set the key for
4752 cipher without using the object's method function. The affected
4753 files: lib/silccrypt/silccipher.[ch].
4755 * Implemented silc silc_client_add_private_message_key,
4756 silc_client_add_private_message_key_ske,
4757 silc_client_del_private_message_key,
4758 silc_client_list_private_message_keys and
4759 silc_client_free_private_message_keys functions in the
4762 Added functions silc_client_send_private_message_key to send
4763 the Private Message Key payload and silc_client_private_message_key
4764 to handle incoming Private Message Key payload.
4766 * Added Cipher field to the Private Message Key payload to set
4767 the cipher to be used. If ignored, the default cipher defined
4768 in the SILC protocol (aes-256-cbc) is used.
4770 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4772 * Removed lib/silcclient/ops.h file.
4774 Redefined parts of the SILC Client Library API. Created new
4775 file silcapi.h that deprecates the ops.h file and defines the
4776 published Client Library API. Defined also private message key
4777 API and channel private key API into the file.
4779 This is the file that the application must include from the
4780 SILC Client Library. Other files need not be included by
4781 the application anymore.
4783 * Added new key_agreement client operation callback and also
4784 defined the Key Agreement library API for the application.
4786 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4789 is used by clients to request key negotiation between another
4790 client in the SILC network. If the negotiation is started it
4791 is performed using the SKE protocol. The result of the
4792 negotiation, the secret key material, can be used for example
4793 as private message key.
4795 Implemented the Key Agreement payload into the files
4796 lib/silccore/silauth.[ch].
4798 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Redefined ciphers for the SILC protocol. Added some new ciphers
4801 and defined the key lengths for the algorithms. Changed the
4802 code accordingly. The default key length is now 256 bits.
4804 * Fixed SKE key distribution function silc_ske_process_key_material
4805 when the key length is more than 128 bits. The default key
4806 length in SILC is now 256 bits.
4808 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4809 to indicate unsupported algorithm.
4811 * Renamed rijndael.c to aes.c and all functions as well.
4813 * Fixed a long standing channel key setting bug in client library.
4814 Weird that it has never surfaced before.
4816 * Fixed bug in channel deletion. If the entire channel is removed
4817 then it must also delete the references of the channel entry
4818 from the client's channel list as the client's channel entry and
4819 the channel's client entry share same memory.
4821 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Implemented CONNECT and SHUTDOWN commands in the client.
4825 * Implemented CLOSE command to the client.
4827 * Added the function silc_idlist_find_server_by_name into the
4828 files silcd/idlist.[ch].
4830 Added the function silc_idlist_find_server_by_conn into the
4831 files silcd/idlist.[ch].
4833 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * DIE command was renamed to SHUTDOWN. Updated the both code
4838 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4839 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4841 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4844 * Added function silc_server_create_connection function to create
4845 connection to remote router. My server implementation actually
4846 does not allow router to connect to normal server (it expects
4847 that normal server always initiates the connection to the router)
4848 so the CONNECT command is only good for connecting to another
4851 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4853 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4854 or some other client was kicked from the channel.
4856 Implemented the handling of the notify type to both client
4859 Implemented silc_server_send_notify_kicked to send the KICKED
4860 notify. It is used to send it to the server's primary router.
4862 * Implemented the KICK command into server and client.
4864 * Added `query' argument to the silc_idlist_get_client function
4865 to indicate whether to query the client from server or not if
4868 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4869 to indicate that the client is not channel founder.
4873 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Removed the rng context from SilcPacketContext structure and
4876 changed that the packet routine uses the Global RNG API.
4878 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Added support for quit message that client can "leave" on the
4881 channel when it quits the SILC. It is ditributed inside the
4882 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4884 Added silc_server_free_client_data that will take the
4885 signoff message as argument.
4887 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4889 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Updated parts of the protocol specification to keep it up
4894 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4896 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4897 payloads in one packet.
4899 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4900 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4901 use now the new List flag.
4903 * Also deprecated the following packet types: REPLACE_ID,
4904 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4906 * Added list support for Notify packet in server.
4908 * Added silc_server_send_notify_channel_change to send the
4909 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4910 the silc_server_send_replace_id.
4912 * Added silc_server_send_notify_nick_change to send the
4913 NICK_CHANGE notify type. Deprecates the function
4914 silc_server_send_replace_id.
4916 * Added silc_server_send_notify_join to send the JOIN notify type.
4917 Deprecates the function silc_server_send_new_channel_user.
4919 * Added silc_server_send_notify_leave to send LEAVE notify type.
4920 Deprecates the function silc_server_send_remove_channel_user.
4922 * Added silc_server_send_notify_cmode and
4923 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4924 types. Deprecates the silc_server_send_set_mode function.
4926 * Added SERVER_SIGNOFF notify type to indicate that server has
4927 quit. This means that all clients on the channel from that
4928 server will drop. This can be also used when netsplit happens.
4930 Deprecated REMOVE_ID packet type since it is not needed anymore
4933 Added silc_server_send_notify_server_signoff to send the
4934 SERVER_SIGNOFF notify type. Deprecates the function
4935 silc_server_send_remove_id.
4937 Added also silc_server_send_notify_signoff to send the
4938 SIGNOFF notify type.
4940 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4941 SILC protocol from this day on. Changed the protocol
4942 specification as well.
4944 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4945 notify type. It is used between routers to notify about
4946 topic changes on a channel.
4948 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4951 * Partly updated the protocol specification to comply with the
4952 changes now made. It is still though a bit outdated.
4954 * The JOIN notify type now takes one extra argument <Channel ID>.
4955 The packet used to be destined to the channel but now the
4956 JOIN type may be sent as list thus it is impossible to
4957 destine it to any specific channel. By adding this argument
4958 it is again possible.
4960 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Added CREDITS file. The CHANGES and CREDITS file will appear
4963 in the distribution as well.
4965 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4968 types in the server's silcd/packet_receive.c.
4970 * Implemented CMODE and CUMODE to work in router environment.
4972 * Fixed minor encoding and decoding buglet from the
4973 lib/silccore/silcmode.c.
4975 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4978 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4980 * Changed all SilcConfigServer* and silc_config_server* to
4981 SilcServerConfig* and silc_server_config*, respectively.
4984 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Associated the ID (client or server ID) to the Authentication
4987 Payload to avoid any possibility of forging. Updated the
4988 protocol specification and the code accordingly.
4990 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * The RSA key length is now save to the RsaKey context in the
4993 key generation process in lib/silccrypt/rsa.c. The key length
4994 is now used to figure out the maximum size of the block allowed
4995 to be encrypted/signed.
4997 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4998 is equivalent to the silc_mp_mp2bin but does not allocate any
5001 * Changed silc_mp_mp2bin API to take length argument. If it is
5002 non-zero then the buffer is allocated that large. If zero, then
5003 the size is approximated using silc_mp_sizeinbase, which however
5006 * Created Global RNG API which is global RNG that application can
5007 initialize. After initializing, any routine anywhere in the
5008 code (including library) can use RNG without allocating a new
5009 RNG object. This was done to allow this sort of use of the
5010 RNG in code that has no chance to allocate RNG object. All
5011 applications currently allocate this and many routines in the
5012 library use this. Affected file lib/silccrypt/silcrng.[ch].
5014 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5015 it to use the Global RNG API.
5017 * Defined Authentication Payload into protocol specification that
5018 is used during SILC session to authenticate entities. It is
5019 used for example by client to authenticate itself to the server
5020 to obtain server operator privileges.
5022 Implemented this payload into the lib/silccore/silcauth.[ch].
5023 Implemented also routines for public key based authentication
5024 as the new protocol specification dictates.
5026 Moved definitions of different authentication methods from
5027 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5029 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5030 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5031 silc_pkcs_verify_with_hash functions into the file
5032 lib/silccrypt/silcpkcs.[ch].
5034 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * The client entry's userinfo pointer must be always valid.
5037 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5038 will fail since it requires the userinfo. Now, the userinfo
5039 is allocated as "" if actual userinfo does not exist. Actually,
5040 it must exist and it is totally Ok to drop client connections
5041 that does not announce the userinfo. However, we will make
5042 this workaround for now.
5044 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5045 to return the remote port by socket.
5047 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5050 SILC_SERVER_PENDING_EXEC and added an new macro
5051 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5052 data or when error occurs while processing the pending command.
5054 Added new argument `destructor' into silc_server_command_pending
5055 and to the SilcServerCommandPending object. This destructor is
5056 now called after calling the pending callback or if error occurs
5057 immediately. If error occurs the actual pending callback won't
5058 be called at all - only the destructor. The destructor may be
5059 NULL if destructor is not needed.
5061 All this applies for client library code as well. Similar
5062 changes were made there as well for the pending commands.
5064 In the client, the application must now allocate the
5065 SilcClientCommandContext with the silc_client_command_alloc
5068 * Added reference counter to the SilcServerCommandContext. Added
5069 function silc_server_command_alloc and silc_server_command_dup
5072 Same type of functions added to the client library for the same
5075 * Removed the cmd_ident from IDListData away since it is now
5076 global for all connections. It is the command identifier used
5077 in command sending and with pending commands. The affected file
5080 * Added reference counter to the SilcSocketConnection objecet to
5081 indicate the usage count of the object. The object won't be
5082 freed untill the reference counter hits zero. Currently only
5083 server uses this, and client ignores it. The client must be
5084 set to use this too later. The affected files are
5085 lib/silccore/silcsockconn.[ch]. Added also the function
5086 silc_socket_dup to increase the reference counter.
5088 This was mainly added because it is possible that the socket
5089 is removed underneath of pending command or other async
5090 operation. Now it won't be free'd and proper DISCONNECTING
5091 flags, etc. can be set to avoid sending data to connection that
5092 is not valid anymore.
5094 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5095 the connection. After that it sets SILC_SET_DISCONNECTED.
5096 It is, however, possible that the socket data is not still freed.
5097 The silc_server_packet_process now checks that data is not
5098 read or written to connection that is DISCONNECTED. The socket
5099 get's freed when the reference counter hits zero.
5101 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Changed the client operation API: channel_message operation's
5104 `sender' is now the client entry of the sender, not the nickname
5105 and the `channel' is the channel entry, not the channel name.
5107 In the private_message operation the `sender' is now also the
5108 client entry of the sender not the nickname.
5110 Affected file is lib/silcclient/ops.h and all applications
5111 using the client operations.
5113 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Moved the calling of ops->connect() from connect_to_server_final
5116 into receive_new_id functin since that is the point when the
5117 client is actually allowed to send traffic to network. The
5118 affected file is lib/silcclient/client.c.
5120 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5123 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5124 (if needs broadcasting) instead of broadcasting the packets one
5125 by one which would make a burst in the network traffic.
5127 * Added `broadcast' argument to the functions in silcd/server.[ch]
5128 silc_server_create_new_channel[_with_id] to indicate whether
5129 to send New Channel packet to primary router.
5131 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Added new function into the silcd/server.[ch] files:
5134 silc_server_create_new_channel_with_id to create new channel with
5135 already existing Channel ID.
5137 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5138 lib/silccore/silcpacket.h. This packet is used t send list of
5139 Set Mode payloads inside one packet. Server uses this to set
5140 the modes for the channels and clients on those channels, that it
5141 announced to the router when it connected to it. The protocol
5142 specification has been updated accordingly.
5144 * The silc_server_new_channel did not handle the packet coming
5145 from normal server as it normally does not send that. However,
5146 when it announces its channels it does send it. Implemented
5147 the support for that.
5149 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5150 into the file lib/silccore/id.h.
5152 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Fixed memory leaks in the functions silc_idlist_del_client,
5155 silc_idlist_del_channel and silc_idlist_del_server in the file
5156 silcd/idlist.c. All of those leaked like a sieve.
5158 * Fixed some small memory leaks in the client's function
5159 silc_client_notify_by_server.
5161 * Added functions into silcd/server.c: silc_server_announce_clients,
5162 silc_server_announce_channels and silc_server_announce_server.
5163 These functions are used by normal and router server to announce
5164 to its primary router about clients, channels and servers (when
5165 router) that we own. This is done after we've connected to the
5168 These functions effectively implements the following packet types:
5169 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5170 and SILC_PACKET_NEW_ID_LIST.
5172 * Added new functions into the silcd/packet_receive.[ch]:
5173 silc_server_new_id_list, silc_server_new_channel_list and
5174 silc_server_new_channel_user_list to handle the incoming
5175 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5177 * Added support of changing Channel ID in the function
5178 silc_server_replace_id. If the server that announces a channel
5179 to the router already exists in the router (with same name but
5180 with different Channel ID), router is responsible to send
5181 Replace ID packet to the server and force the server to change
5182 the Channel ID to the one router has.
5184 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5185 client that the Channel ID has been changed by the router. The
5186 normal server sends this to the client. Client must start using
5187 the new Channel ID as the channel's ID.
5189 Implemented handling of this new type into lib/silcclient/client.c
5190 into the function silc_client_notify_by_server.
5192 * Added new function silc_idlist_replace_channel_id into the files
5193 silcd/idlist.[ch] to replace the Channel ID.
5195 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Call silc_server_command_identify_check always when processing
5198 the IDENTIFY command in silcd/command.c
5200 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5203 send keepalive packets. The packet can be sent by clients,
5204 servers and routers.
5206 Added function silc_socket_set_heartbeat into the file
5207 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5208 If not set, the heartbeat is not performed. The actual
5209 heartbeat is implemented in the low level socket connection
5210 library. However, application is responsible of actually
5213 Added silc_server_send_heartbeat to send the actual heartbeat
5214 packet into silcd/packet_send.[ch]. Server now performs
5215 keepalive with all connections.
5217 * Added silc_task_get_first function into lib/silcutil/silctask.c
5218 to return the timeout task with shortest timeout. There was a bug
5219 in task unregistration that caused problems. TODO has been
5220 updated to include that task system must be rewritten.
5222 * The client library will now resolve the client information when
5223 receiving JOIN notify from server for client that we know but
5224 have incomplete information.
5226 * Rewrote parts of silc_server_remove_from_channels and
5227 silc_server_remove_from_one_channel as they did not remove the
5228 channel in some circumstances even though they should've.
5230 * Encryption problem encountered in server:
5232 The LEAVE command used to send the Channel Key packet to the
5233 router immediately after generating it. However, the code
5234 had earlier sent Remove Channel user packet but not immediately,
5235 ie. it was put to queue. The order of packets in the router
5236 was that Channel Key packet was first and Remove Channel User
5237 packet was second, even though they were encrypted in the
5238 reverse order. For this reason, MAC check failed. Now, this
5239 is fixed by not sending the Channel Key packet immediately but
5240 putting it to queue. However, this is more fundamental problem:
5241 packets that are in queue should actually not be encrypted
5242 because packets that are sent immediately gets encrypted
5243 actually with wrong IV (and thus MAC check fails). So, packets
5244 that are in queue should be encrypted when they are sent to
5245 the wire and not when they put to the queue.
5247 However, the problem is that the current system has not been
5248 designed to work that way. Instead, the packet is encrypted
5249 as soon as possible and left to the queue. The queue is then
5250 just purged into wire. There won't be any fixes for this
5251 any time soon. So, the current semantic for packet sending
5254 o If you send packet to remote host and do not force the send
5255 (the packet will be in queue) then all subsequent packets to the
5256 same remote host must also be put to the queue. Only after the
5257 queue has been purged is it safe again to force the packet
5260 o If you send all packets immediately then it safe to send
5261 any of subsequent packets through the queue, however, after
5262 the first packet is put to queue then any subsequent packets
5263 must also be put to the queue.
5265 Follow these rules and everything works fine.
5267 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Added new function silc_server_remove_clients_by_server to
5270 remove all client entries from ID list when the server connection
5271 is lost. In this case it is also important to invalidate all
5272 client entires as they hold the invalid server entry. This
5273 fixes fatal bug when server has lost connection and will reconnect
5276 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Made some sanity checks to silc_server_daemonise like to check
5279 whether the requested user and group actually exists.
5281 * Added sanity check to SKE's silc_ske_responder_finish to check
5282 that the public and private key actually is valid.
5284 * Invalidate the client's nickname when receiving Replace ID
5285 packet and the Client ID is being replaced. This means that the
5286 server will query the nickname if someone needs it (client)
5289 * Sort the ID Cache in client library when the ID Cache data
5290 has changed (needs sorting).
5292 * Do not allow for SILC client to create several connections to
5293 several servers. The client does not support windows right now
5294 and generating multiple connections causes weird behaviour.
5296 Irssi-silc client does support windows and can handle several
5297 connections without problems, see: www.irssi.org and SILC plugin.
5299 * Fixed some places where client was added to the IDList. The
5300 rule of thumb is following (in order to get everything right):
5301 If the client is directly connected local client then the
5302 `connection' argument must be set and `router' argument must be
5303 NULL to silc_idlist_add_client function. If the client is not
5304 directly connected client then the `router' argument must
5305 bet set and the `connection' argument must be NULL to the
5306 silc_idlist_add_client function.
5308 * The funtion silc_server_packet_send_local_channel actually did
5309 not check whether the client was locally connected or not. It
5310 does that now. Fixed a bug related to LEAVE command.
5312 * Fixed Remove Channel User payload parsing bug in server's
5313 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5315 * The server's silc_server_save_channel_key now checks also the
5316 global ID list for the channel as it might not be in the local
5317 list. Fixed a bug related to LEAVE command.
5319 * Is this the end of the [<unknown>] buglet that has been lurking
5320 around for a long time? A little for loop fix in server's
5321 silc_server_command_whois_parse that is used by both IDENTIFY
5322 and WHOIS command. At least, this was a clear bug and a cause
5323 of one type of [<unknown>] buglet.
5325 * WHOIS and IDENTIFY commands call the function
5326 silc_server_command_[whois/identify]_check function even if
5327 we are not router server.
5329 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Added --with-gmp configuration option. If set the GMP
5332 is always compiled in the SILC source tree. If not set then
5333 it is checked whether the system has the GMP3 installed. If
5334 it has then the GMP won't be compiled (the system's headers
5335 and library is used), if it doesn't have it then the GMP is
5336 compiled in the SILC source tree.
5338 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Changed RSA private exponent generation to what PKCS #1
5341 suggests. We try to find the smallest possible d by doing
5342 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5343 not security fix but optimization.
5345 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5347 * Added new config entry [Identity] to fork the server and run
5348 it as specific user and group. A patch from Bostik.
5350 * Imported Dotconf configuration library into lib/dotconf.
5351 This will be used to create the SILC configuration files later.
5352 It will appear in the distsribution after this commit.
5354 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5356 * A big code auditing weekend happening. Auditing code for
5357 obvious mistakes, bugs and errors. Also, removing any code
5360 Removed files for being obsolete:
5362 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5363 inline in the file lib/silcutil/silcbuffer.h)
5365 o lib/silcutil/silcbufutil.c (the header has inline versions)
5367 Changed code to fix possible error conditions:
5369 o The buffer formatting routines now check that the destination
5370 buffer really has enough space to add the data. This applies for
5371 both buffer formatting and unformatting
5372 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5373 unformatting was changed to accomodate following rules:
5374 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5375 sent to the function while XXX_*STRING will not allocate or copy
5376 the data into the buffer. Instead it sets the pointer from the
5377 buffer into the pointer sent as argument (XXX_*STRING used to
5378 require that the pointer must be allocated already). This change
5379 makes this whole thing a bit more consistent and more optimized
5380 (note that the data returned in the unformatting with XXX_*STRING
5381 must not be freed now). The routines return now -1 on error.
5383 o Tried to find all code that use buffer_format and buffer_unformat
5384 and added return value checking to prevent formatting and
5385 especially unformatting errors and possible subsequent fatal
5388 o Changed ske->x and ske->KEY to mallocated pointers in
5389 lib/silcske/silcske.h. Fixed possible data and memory leak.
5391 o Added return value checking to all *_parse* functions. Fixed
5392 many memory leaks as well.
5394 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5395 so that buffer overflows would not happen. All code now also
5396 checks the return value as it can fail.
5398 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Added reconnection support to server if the normal server looses
5401 its connection to the router (for example if router is rebooted).
5402 The server performs normal reconnection strategy implemented
5403 to the server. Affected file silcd/server.c.
5405 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Added new packet type SILC_PACKET_SET_MODE that is used to
5408 distribute the information about changed modes (for clients,
5409 channels and clients channel modes) to all routers in the
5410 network. Updated the protocol specification accordingly.
5412 Added functions into silcd/packet_send.c and
5413 silcd/packet_receive.c: silc_server_send_set_mode,
5414 silc_server_set_mode.
5416 Added new files silcmode.[ch] into lib/silccore that implements
5417 the encoding and decoding of Set Mode Payload. Added new type
5418 SilcSetModePayload. Moved the definitions of different modes
5419 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5421 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Oops, a little mistake in server's connection authentication
5424 protocol. The protocol is not ended with FAILURE but with
5425 SUCCESS if the authentication is Ok. :) Affected file is
5428 * Implemented NICK_CHANGE notify handling in server in the file
5429 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5430 the local clients on the channel. After the changing nickname
5431 in router environment snhould work and the [<unknown>] nickname
5432 should appear no more.
5434 The silc_server_replace_id function that receives the Replace ID
5435 payload now sends the NICK_CHANGE notify type also in the file
5436 silcd/packet_receive.c
5438 * Changed WHOIS and IDENTIFY command to support the maximum amount
5439 of arguments defined in protocol specs (3328 arguments). This
5440 fixed a bug that caused problems when there were more than three
5443 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Added extra parameter, command identifier, to the
5446 silc_client_send_command so that explicit command identifier
5449 Changed that ID list routines uses specific command identifier
5450 when sending WHOIS/IDENTIFY requests to the server so that they
5451 can be identified when the reply comes back.
5453 Affected files lib/silcclient/command.[ch],
5454 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5456 * Added `sender' argument to silc_server_packet_send_to_channel
5457 to indicaet the sender who originally sent the packet to us
5458 that we are now re-sending. Ignored if NULL. Affected file
5459 silcd/packet_send.[ch].
5461 * Added some server statistics support in silcd/server_internal.h
5462 SilcServerStatistics structure and around the server code. Also
5463 send some nice statistics information when client is connecting
5466 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Fixed channel ID decoding in server's JOIN command reply in
5469 silcd/command_reply.c
5471 * Fixed braodcasting of replace ID payload to not to send it if
5472 we are standalone server in silcd/packet_receive.c.
5474 * Fixed all channel message sending routines to not to send
5475 packets to clients that has router set, since they are routed
5476 separately in the same function earlier. Affects file
5477 silcd/packet_send.c and all channel packet sending functions.
5479 * In USERS reply, res_argv[i] are not allocated, the table
5480 is allocated. Thus changed that free the table, not its
5483 * In server's whois_check and identify_check if the client is
5484 locally connected do not send any WHOIS commands - they are not
5487 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5489 * Fixed some minor bugs in client when sending WHOIS command. The
5490 arguments was in wrong order.
5492 * Removed statis function add_to_channel from server in
5493 silcd/command.c that was previously used with the joining but
5496 * Tested USERS command in router environment successfully with two
5497 routers, two servers and two clients.
5499 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Reorganized the USERS command and command reply in client library
5502 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5503 When the command is given by user we register a pending command
5504 callback that will reprocess the command after the reply has been
5505 received from the server. When reprocessing the packet we then
5506 display the information. Thus, the USERS information is displayed
5507 now in the command callback instead of in the command reply
5508 callback. The processing of the command is same as previously
5509 when server has sent the command reply in the JOINing process.
5511 * Added to USERS command in silcd/command_reply.c to join the client,
5512 we didn't use to know about, to the channel after we've created
5513 a client entry for it. Also, for clienet we did know already still
5514 check whether it is on the channel or not and add it if not.
5516 * Removed silc_server_command_join_notify as the function and its
5519 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5521 * Changed the client's pending command handling to the same as the
5522 server's pending command handling. It is also now possible to
5523 execute command reply functions from other command reply
5524 function as the function callbacks for commands and command
5525 replies are one and same. The pending commands are not static
5526 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5527 in client connection context. Thus, pending commands are server
5528 connection specific as it is convenient.
5530 Changed the function silc_client_command_pending and
5531 silc_client_command_pending_del and added new function
5532 silc_client_command_pending_check. Removed the
5533 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5536 * Added cmd_ident, current command identifier, to the client
5537 connection context in lib/silcclient/client.h to keep track on
5538 command identifiers used in command sending. Client's command reply
5539 function handling now supports the mandatory command identifiers.
5541 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5542 funtions in client to fully support pending command callbacks.
5544 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5545 as one of the arguments to the application in the command reply
5548 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5549 before first releasing SILC but came back. Now it is removed again
5550 and should come back nomore. The FORWARDED flag was used only
5551 by the JOINing procedure by forwarding the command packet to router.
5552 Now, the JOINing procedure has been changed to more generic (due
5553 to various router environment issues) and FORWARDED is not needed
5554 anymore for anything. The protocol specification is yet to be
5557 Now, removed silc_server_packet_forward from server and the flag
5558 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5560 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * Renamed NAMES command to USERS command. The NAMES was named that
5563 due to historical reasons. Now it is renamed. Also, rewrote
5564 parts of the USERS command. The nickname list is not sent anymore
5565 by the server. Only Client ID and mode lists are sent in the USERS
5566 command. Changed this also to the protocol specification.
5568 The client now resolves the names and stuff after it receives
5569 the USERS list from the server when joining to the channel.
5571 * WHOIS and IDENTIFY commands has been changed to support multiple
5572 Client ID's per command. One can now search for multiple users
5573 in the network by sending only one WHOIS or IDENTIFY command.
5574 Changed the code and the protocol specifications.
5576 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5577 uses silc_server_command_whois_parse to parse the request. */
5579 * If normal server, do not parse the WHOIS and IDENTIFY requests
5580 before sending it to the router. Saves some time.
5582 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5584 * Fixed JOIN command on client library. Wrong number of arguments
5585 used to crash the client.
5587 * Added silc_server_channel_has_global function to check whether
5588 channel has global users or not.
5590 * Added silc_server_channel_has_local function to check whether channel
5591 has locally connected clients on the channel.
5593 * The silc_server_remove_from_one_channel now checks whether the
5594 channel has global users or not after given client was removed from
5595 the channel. It also checks whether the channel has local clients
5596 on the channel anymore. If it does not have then the channel entry
5597 is removed as it is not needed anymore.
5599 * The silc_server_notify now checks on JOIN notify whether the joining
5600 client is one of locally connected or global. If it is global then
5601 the channel has now global users on the channel and that is marked
5602 to the channel entry. Also, it now saves the global client to
5603 global list who is joining and JOINs it to the channel. This is
5604 for normal server, that is.
5606 Changed silc_server_send_notify_on_channel,
5607 silc_server_packet_relay_to_channel and
5608 silc_server_packet_send_to_channel check if we are normal server
5609 and client has router set (ie. global client) do not send the
5610 message to that client, as it is already routed to our router.
5612 * Implemented LEAVE notify type handling in silc_server_notify
5615 * Tested LEAVE command in router environment successfully. Tested
5616 with two routers, two servers and two clients.
5620 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5622 * Implemented SIGNOFF notify type handling in silc_server_notify
5625 * silc_server_remove_id now removes the client entry from all channels
5626 it has joined and thusly sends SIGNOFF notify type.
5628 * Rewrote the NAMES list generation in server by removing two excess
5629 loops. The lists are created now inside one loop.
5631 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * silc_server_remove_channel_user checks now also global list
5634 for channel and client.
5636 * silc_server_new_channel_user checks now both local and global
5637 list for channel and client. Fixed a bug in client id decoding.
5638 Used to decode wrong buffer.
5640 * silc_server_channel_message checks now both local and global
5641 list for channel entry.
5643 * Tested channel joining (hence JOIN) in router environment
5644 successfully. Tested with two routers, two servers and two
5647 * Tested channel message sending in router environment successfully.
5649 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Added silc_server_save_channel_key into server.[ch] to save the
5652 received channel key in Channel Key payload processing. It is
5653 also used in JOIN command reply handling.
5655 Equivalent function silc_client_save_channel_key added into
5656 client.[ch] into client library.
5658 * Changed JOIN command reply to send information whether the channel
5659 was created or not (is existing already) and the channel key
5660 payload. Changed protocol specs accordingly.
5662 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5663 the request was sent by ID and not by nickname. Crashed on
5666 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5669 now correctly save the received data.
5671 * silc_server_free_sock_user_data now notifies routers in the
5672 network about entities leaving the network.
5674 At the same time implemented functions silc_server_remove_id
5675 and silc_server_send_remove_id to receive and send REMOVE_ID
5676 packets. The packet is used to notify routers in the network
5677 about leaving entities. The ID removed will become invalid in
5680 * Added function silc_idlist_del_server into server. Removes and
5681 free's server entry from ID list.
5683 * silc_server_private_message function now checks, if we are router,
5684 that the destination ID really is valid ID, naturally.
5686 * In router when NEW_ID packet is received (for new client) the
5687 hash of the Client ID is saved in the ID Cache but the
5688 client->nickname is set to NULL, instead of putting the hash
5691 IDENTIFY command now also checks that client->nickname must be
5692 valid. If it is not if will request the data from the server who
5693 owns the client. Added new function
5694 silc_server_command_identify_check.
5696 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5697 to set the command to already allocated Command Payload.
5699 * Tested private message sending in router environment with two
5700 routers, two servers and two clients. Fixed minor bugs and now
5703 * Fixed segfault from client's NAMES command. Used to crash if
5706 * Forwarded packets must not be routed even if it is not destined
5707 to the receiver. Changed server code comply with this.
5709 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Added `require_reverse_mapping' boolean value to ServerParams
5712 structure. If TRUE (not default) the server will require that
5713 the connecting host has fully qualified domain name.
5715 If the reverse mapping is not required and hostname could not be
5716 found the IP address is used as hostname.
5718 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Implemented version string checking to both client and server.
5721 The check is incomplete currently due to the abnormal version
5722 strings used in development version of SILC.
5724 * Changed all command functions in server to use the new
5727 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Changed char *data to unsigned char *data in ID Cache system to
5730 support binary data as ID Cache data. Changed code to support
5731 binary data in lib/silccore/idcache.c.
5733 * Renamed silc_server_packet_relay_command_reply to
5734 silc_server_command_reply as it is normal packet receiving
5735 function. Rewrote the function to accept command replys for
5736 servers and not only for clients.
5738 * Mark remote router always as registered server if we are connecting
5739 to it. Otherwise, commands sent by the router to us are ignored.
5741 * All ID List find routines now returns the ID Cache Entry pointer
5742 as well if requested.
5744 * WHOIS command works now in router environment, tested with two
5745 routers, two servers and two clients.
5747 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5748 in router environment (as it is almost equivalent to WHOIS) but
5749 hasn't been tested thoroughly. Added new functions:
5751 silc_server_command_identify_parse
5752 silc_server_command_identify_send_reply
5753 silc_server_command_identify_from_client
5754 silc_server_command_identify_from_server
5756 * Disabled route cache adding because adding two different ID's with
5757 same IP replaces the old cache entry thus giving wrong route.
5758 The entry->router->connection is always the fastest route anyway
5759 so route cache may not be needed. Of course, new routes maybe
5760 established after receiving the ID when the entry->router->connection
5761 might not be anymore the most optimal.
5763 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Add route cache for received ID for fast routing.
5767 * Added silc_server_packet_route to route received packet on router
5768 that is not destined to us.
5770 * Renamed silc_server_get_route to silc_server_route_get.
5772 * Added id_string and id_string_len fields into SilcServer to
5773 include encoded ServerID for fast comparing without excess
5774 encoding of the ID's.
5776 * Cleaned up WHOIS command on server side. Added following static
5779 silc_server_command_whois_parse
5780 silc_server_command_whois_check
5781 silc_server_command_whois_send_reply
5782 silc_server_command_whois_from_client
5783 silc_server_command_whois_from_server
5785 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5786 arguments in command replies. All command functions should be
5787 updated to use this macro.
5789 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Minor typo fixes on command reply handling on server.
5793 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Added silc_server_command_add_to_channel internal routine to add
5796 the client to the channel after router has created the channel and
5797 sent command reply to the server.
5799 * Added generic silc_server_send_command to send any command from
5802 * Use static buffer with ID rendering instead of duplicating data.
5804 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Fixed a channel user mode bug when joining to a channel server gave
5807 everybody channel founder rights, oops.
5809 * We mark ourselves as the router of the incoming server connection
5810 if we are router ourselves. This way we can check in some packet
5811 sending functions whether it is locally connected server. For
5812 incoming router connections we put NULL.
5814 * For router sending packets locally means now always sending the
5815 packet cell wide; to local clients and local servers. For normal
5816 server sending packet locally means sending it to only local
5819 * Fixed the JOIN command to really work in router environment. If the
5820 channel is created it is always created by the router. Router is
5821 also responsible of making the initial joining to the channel,
5822 sending JOIN notify to the sending server and distributing
5823 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5824 does not exist server doesn't do anything else but forward the
5825 command to the router which performs everything.
5827 * Added silc_server_send_channel_key function to send the Channel Key
5830 * Added silc_server_create_channel_key to create new channel key. The
5831 channel key is now re-generated everytime someone joins or leaves
5832 a channel, as protocol dictates. Note: channel->key_len is the
5835 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5838 packet_receive.[ch] to separate packet sending and receiving
5839 routines. The server.[ch] now includes everything else including
5840 actual packet processing (writing and reading data) and other
5843 Renamed silc_server_private_message_send_internal to
5844 silc_server_send_private_message. The routine is still though
5845 used only to relay private messages as server does not send
5846 private messages itself.
5848 Renamed silc_server_new_channel to silc_server_create_new_channel
5849 and added new function sicl_server_new_channel that handles the
5850 incoming New Channel packet. Added also new sending function
5851 silc_server_send_new_channel to send New Channel Payload.
5853 * Added new function silc_server_notify to process incoming notify
5854 packet to the server/router. Server may then relay the notify
5855 to clients if needed.
5857 * Added new function silc_server_new_channel_user to process incoming
5858 New Channel User packet. Router will redistribute the packet and
5859 send JOIN notify to its local clients and locally connected servers
5860 if needed. Normal server will send JOIN notify to its local client
5861 on same channel when received this packet. Added also corresponding
5862 sending function silc_server_send_new_channel_user to sent the
5865 * Added boolean route argument to send_notif_to_channel and
5866 packet_send_to_channel functions to attempt to route the packet
5867 if it is TRUE and send only locally if it is FALSE.
5869 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * silc_server_replace_id now broadcasts the received replace ID
5872 packet if it is not broadcast packet already. The router must
5873 broadcast to inform other routers about changed ID.
5875 * Added backpointer to server's router into SilcServer context in
5876 silcd/server_internal.h.
5878 * Fixed silc_server_packet_broadcast to send correct broadcast
5881 * The channel key is now distributed to the local client as soon
5882 as it is received from the router (in router environment) so that
5883 no other packet may be sent for the channel until client has
5886 * silc_server_remove_channel_user now broadcasts the received
5887 Remove Channel User packet if it is not broadcast packet already.
5888 The router must broadcast to inform other routers about removed
5891 * Added users field into SilcPacketContext that is a reference count
5892 of the context. One can increase the reference count by calling
5893 silc_packet_context_dup which is now changed to just increase the
5894 reference count instead of duplicating the data. The reference
5895 count is decresed by calling silc_packet_context_free that will
5896 free the data after the reference count hits zero.
5898 For now on the packet context and everything allocated into it
5899 (including the raw packet from network) must be freed by calling
5900 the new silc_packet_context_free function. Added also new function
5901 silc_packet_context_alloc that must be used now to allocate the
5902 context. This also means that if a routine is asynchronous from
5903 silc_[client/server]_packet_parse_type the packet context must
5904 be duplicated by calling silc_packet_context_dup. Otherwise it
5905 gets free'd after silc_[client/server]_packet_parse_type returns.
5906 Also, one must remember that if packet is duplicated then its
5907 reference count must be decresed by calling the free function as
5908 many times as it was duplicated.
5910 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5911 from both client and server.
5913 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Made joining to a channel working in router environment.
5917 * Cleaned up JOIN command on server side and create function
5918 silc_server_command_join_channel internal routine to make the
5921 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5923 * Changed silc_command_pending list to SilcDList. Also, added
5924 `ident' field to SilcServerCommandPending structure to identify
5925 the reply and to call correct callback.
5927 Added silc_server_command_pending_check function to replace the
5928 corresnponding macro. The silc_command_pending list is not
5931 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5932 to set identifier to previously allocated Command Payload. It
5933 is used to set identifier for command when resending Command
5936 * Added silc_command_payload_encode_payload to encode Command
5937 Payload buffer from SilcCommandPayload structure.
5939 * Added silc_argument_payload_encode_payload to encode Argument
5940 payload buffer from SilcArgumentPayload structure.
5942 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Changed WHOIS command to support router connection on server side.
5945 The whois request is always sent to router unless the server is
5946 standalone server. After server has received the reply from the
5947 router will it send the reply to the client.
5949 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5950 broadcast received broadcast packet. The function is used only
5951 by router. The broadcast packet is always sent to the router's
5954 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5955 render given ID to printable string, for log files for example.
5957 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Made basic router to router connections working. At least they
5960 can now connect to each other but nothing really works the way
5961 they are supposed - yet.
5963 * Added new initiator token to RouterConnection configuration
5964 file in silcd/serverconfig.[ch]. It is used to tell whether we
5965 are the initiator to the remote router or whether we'll expect
5966 the other end to connect.
5968 * Moved registering of listener task to silc_server_init, hence
5969 the server starts listenning as soon as it is run, even if it
5970 does not have connections to other routers. Let's see how well
5973 * Changed default connection retry timeouts for more suitable in
5976 * Removed cipher and such arguments from silc_idlist_add_client
5977 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5978 Added new function silc_idlist_add_data to add the keys and stuff
5981 * Added SilcIDListData structure and added it to SilcClientEntry
5982 and SilcServerEntry as their first field in the structure. This
5983 way we can explicitly cast the ID entries to the SilcIDListData
5984 structure and get common data for the entries. In past, we had
5985 to first check what type of connection it is and then cast it to
5986 correct ID entry type. Now, we can directly cast the opaque
5987 pointer to the SilcIDListData (no matter what ID entry it actually
5988 is) and get the data needed.
5990 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5993 in some circumstances even if threre were timeout tasks, though not
5994 IO tasks, but tasks anyway. Now fixed.
5996 * Defined SilcServerConnection structure to hold connection specific
5997 stuff about directly connected servers and routers. The definition
5998 is currently in silcd/server_internal.h. I thought about having
5999 a bit more important role fro this struct but for now it is used
6000 only when connecting to other server (or router actually).
6002 * Added connecting retry support in server when connecting to
6003 router(s). The retry feature implement exponential backoff
6004 algorithm. Also, added SilcServerParams structure to hold default
6005 parameters for server. For now, it include these retry settings
6006 and are hard coded. After server is moded to be as Silc Server
6007 Library this structure will be more important.
6009 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6011 * Changed client librarys channel->clients table to SilcList and
6012 changed code accordingly.
6014 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * Changed client's channel table to SilcList and changed code
6017 accordingly. Also changed SilcChannelClientEntry to include back-
6018 pointer to the channel so that client entry can use that structure
6019 as list as well and we have fast cross-reference to the channel.
6020 This change dramatically decreased the complexity of channel
6021 handling with client entry and vice versa (removed one extra
6022 loop when searching for channel entry from many functions).
6024 * Changed server->sim from table to SilcDList and changed code
6027 * NAMES command can now be used from user interface. It will show
6028 the user list on the channel, neatly.
6030 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6031 Code now saves realname of the user if it becomes available.
6033 * Renamed configure.in to configure.in.pre and made ./prepare
6034 script to automatically add correct version string to
6035 configure.in which it creates from configure.in.pre.
6037 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * NAMES command reply now shows users mode with the nickname when
6042 * Moved silc_client_ch[u]mode[_char] functions from
6043 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6044 place sucks, they are utility functions and should be in some
6047 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6049 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6052 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6056 * Added TRQ (efficient deque and list library) into lib/trq. This is
6057 a very good list library that is currently used in the SILC. Defined
6058 SilcList API over the library because I didn't like the API very
6059 much. See lib/trq/silclist.h for the API and examples of how to
6060 use the API. Fixed various places in the code to use the new
6061 SilcList API. The SilcList is meant for lists that has a structure
6062 already defined as a list. It is not suitable to add just some
6063 context to the list (in TRQ, the context is the list actually).
6065 So, I defined SilcDList that can be used for the purpose where
6066 predefined list structure does not exit. This can be used as
6067 such list. Now some context just can be added to the SilcDList.
6068 Currently this list is not used in the SILC just yet, though there
6069 are a lot places where this can replace dynamically allocated
6070 tables and I will fix these places, later, to use SilcDList.
6071 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6072 and use TRQ internally).
6074 Also fixed some annoying warning messages that the original TRQ
6075 code generated. Also minor changes to TRQ's Makefile.in.
6077 * Added support for querying by Client ID to both WHOIS and
6078 IDENTIFY commands into server, as required by the protocol.
6080 * Removed method function pointers from SilcBuffer structure. They
6081 weren't used to anything and just increased the context size for
6082 no good reason. This change also made silc_buffer_alloc and
6083 silc_buffer_free functions inline functions.
6085 * Disabled command flooding detection support until it's fixed so
6086 that it accepts commands in but does not execute them more than once
6089 * Added silc_net_localhost(), to return local hostname, into
6090 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6091 that must be initialized before calling silc_client_init.
6093 * Added new function: silc_server_send_notify_on_channels to send
6094 notify messages to all channels client has joined. It is assured
6095 that the message is sent only once per client.
6097 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6098 lib/silcutil/silcutil.[ch] as silc_format function. The new
6099 function is generic and is used by server as well, not only by
6100 the logging routines.
6102 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6103 the provided version string was not acceptable. Added new function:
6104 silc_ske_check_version into lib/silcske/silcske.h. The function
6105 must be implemented by the application (client or server) and it
6106 does not reside in the SKE library. The function checks the version
6107 string remote end sent.
6109 * Added back pointers (to opaque context and to SilcSocketConnection)
6110 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6112 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6113 duplicate packet context structure.
6115 * Changed `notify' client operation to send same arguments as client
6116 receives from server except for ID's. ID's are mapped to correct
6117 ID entry and that is returned. Also, if channel entry is not sent
6118 by server but the notify is for channel the channel entry is sent
6119 to application (otherwise application doesn't know that it is for
6120 channel (library gets it from packet's Destination ID)).
6122 * Added silc_client_remove_from_channels into client library to
6123 remove a client from all channels it has joined to. Used when
6124 received SIGNOFF notify from server. Added also new function
6125 silc_client_replace_from_channels to replace old ID entry with
6126 new ID entry on all channels. Used when received NICK_CHANGE
6129 * Fixed ID Cache list handling in silc_idlist_get_client in
6130 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6131 to get (or query) client by ID.
6133 * Updated TODO list.
6135 * Added connection authentication status message defined by the
6136 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6137 support for these into the code in client and server side.
6139 * Added generic function silc_client_send_command to send any command
6140 with variable argument list. Application should use this function
6141 to send commands if the command functions provided by the library
6142 does not suite for the application's user interface needs.
6144 * Added new `failure' client operation. Application is notified about
6145 received failure packet if client is executing a protocol. In this
6146 case the protocol's execution has failed.
6148 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6149 is required by the protocol.
6151 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6152 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6155 * Added status flag to SilcSKE object to indicate realtime status
6156 of the SKE protocol.
6158 * Application receives now exactly same command reply arguments as
6159 the library receives from server. However, if ID is received the
6160 corresponding ID entry is returned to the application (eg. Client
6161 ID is mapped to correct SilcClientEntry entry and that is returned).
6162 Changed command_reply client operation due to this change.
6164 * Changed all ID's in commands and in command replys as ID Payloads.
6165 Change affected both client and server side codes.
6167 All ID's sent in SILC network (with execption of ID's in SILC
6168 Packet header) are sent in ID Payload to support variable length
6171 * Server now notifies nick changes and notifies all clients on
6172 the channels about the new nickname (about the new Client ID,
6175 * Implemented CMODE command to change channel modes. Supports all
6176 channel modes defined by the protocol specs except ban and invite
6177 lists. (Also, private channel key mode is supported but support for
6178 setting private channel key in client is missing, thus, this mode
6179 has no effect on client side (except that server requires that the
6180 client uses private channel key and normal channel traffic does not
6183 Also, invite mode works per se, but INVITE command does not work
6184 yet correctly, so you can set channel as invite only channel but
6185 inviting clients to the channel does not work (it is yet to be
6186 thought what's the best way to do it).
6188 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6189 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6190 Implemented CUMODE command to change user's mode on the channel.
6191 Supports all modes defined by the protocol specs.
6193 * Added NAMES command reply to return users modes on the channel.
6195 * Removed unnecessary and slow ciphers from lib/silccrypt.
6197 * Set SO_KEEPALIVE option to connection sockets by default.
6199 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6201 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6202 redefined the Notify Payload into protocol specs.
6204 * Added silc_id_payload_parse_id to get ID directly from raw
6207 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6209 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6210 accept searching by Client ID as well.
6212 * Added support for LEAVE and SIGNOFF notify types in client library.
6214 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6215 to parse ID Payload from raw data.
6217 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6219 * Added flags parameter into silc_ske_assemble_security_properties
6220 function in lib/silcske/silcske.[ch].
6222 * Changed notify client operation to fit better for notify messages
6223 sent by server. The notify payload received from server is now
6224 passed to the application (after parsing it to SilcNotifyPayload).
6225 It is application's responsibility to retrieve the arguments
6226 from the payload and show the message the way it wants. The message
6227 sent by server is implementation specific.
6229 * Changed public keys to comply with the protocol specification.
6230 Old public keys are not supported anymore and are not compatible.
6232 * Removed nickname from Channel Payload as the latest draft removed
6233 it. The client must resolve the nickname from the NAMES command
6234 reply received when it joined the channel.
6236 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6238 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * Fixed some errors in protocol specification drafts.
6242 * Created lib/silccore/silcnotify.c to implement Notify Payload
6243 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6244 generic payloads described by protocol specifications. The file
6245 includes implementations for ID Payload and Argument Payload.
6247 * Changed Command Payload implementation to use the new Argument
6248 Payload. Changed command_xxxx_payload to command_payload_xxxx
6249 to comply with SILC coding conventions.
6251 * Added suppport for Argument Payload handling in Notify Payload
6252 implementation as protocol requires it. Added the new support
6253 into server and client lib as well.
6255 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Added support for multiple nicknames on same channel. [n] is
6258 added locally to the nickname if there are more than one same
6259 nicknames on the channel.
6261 * Server now sends all nicknames that matched WHOIS request.
6262 Client also shows the list received from server.
6264 * Added TOPIC command to client side. User can now set and show
6265 current topic on channel.
6267 * Added MOTD command to client and server. Also, server sends the
6268 motd when client connects to the server.
6270 * Changed version strings to comply ISO 8601.
6272 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Fixed protocol error handling in client library. It should now
6275 cope even if the SKE fails for some reason.
6277 * Made new protocol specification drafts for submitting to IETF.
6279 * Implemented TOPIC command to server in silcd/command.c.
6281 * Added two new notify types into lib/silccore/silcnotify.h:
6282 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6283 notify nickname change and topic setting/change on a channel.
6285 * API change of command_reply operation in client library. The
6286 application gets now the status type received from server as well.
6288 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6292 * Cras fixed and optimized the packet handling even further and
6293 it should work now. Minor change to the prototype of function
6294 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6296 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Added new function into lib/silcutil/silcschedule.[ch]:
6299 silc_schedule_with_fd to select() a specified fd. The function
6300 returns after timeout expires or data arrives or goes. The
6301 function is used by packet routines to wait that all data is
6302 received from network.
6304 * Fixed data reading from network in lib/silccore/silcpacket.c.
6305 The code now assures that all data is read from the fd and then
6306 continues packet processing. This was a bug fix since the code
6307 used to drop some data in some circumstances.
6309 * Added new function into lib/silcclient/client.[ch]:
6310 silc_client_start_key_exchange to start key exchange after
6311 connection has been established to server. The code internally
6312 now uses this funtion but its main purpose was to provide it
6313 for applications that perform their own connecting. After
6314 application has created a connection it merely calls this
6315 function to start the key exchange between client and server.
6316 The library takes care of everything else after that.
6318 Updated also lib/silcclient/README to explain the usage of
6321 * Do not send to application information that connection has
6322 been established. Application gets notified it by connect
6325 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Applied cras's patch to add silc_schedule_one function. The
6328 function runs scheduler once and returns.
6330 * Fixed the scheduler after cras messed it up. The timeout
6331 handling works now as it's supposed to work.
6333 * Added into lib/silccore/ silcnotify.h to include notify
6334 message types support. Changed silc_server_send_notify*
6335 functions, in server.[ch], to support those new notify types.
6336 Added the support for the notify types into client library,
6337 as well. Added new notify client operation into ops.h in
6340 * Changed silc_server_packet_send_to_channel to send normal
6341 packets instead of just channel message packets. The function
6342 is now used to send the notify packets to channels. It is not
6343 used to send channel message packets anymore, as server never
6346 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6347 va_arg()s as it seems to require it nowadays. I guess, if SILC
6348 is compiled with older va_arg() the new code should work anyway.
6350 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6352 * Splitted core library. Core library (lib/silccore) includes
6353 now only SILC protocol specific core (and common) components.
6354 Created new utility library (lib/silcutil) that includes more
6355 generic purpose stuff. The stuff for util library was taken
6356 from the old core library. This was minor and easy split.
6358 * Created SILC Client Library (lib/silcclient) that includes
6359 implementation of the SILC client without user interface. This
6360 was major move from silc/ directory. The code has been changed
6361 so that it is transparent towards the user interface. The
6362 silc/ directory includes now the same user interface as before
6363 and it uses the new client library. Read lib/silcclient/README.
6364 Basicly, the client library performs everything else related
6365 to SILC except user interface handling. Also, configuration
6366 files are considered to be part of user interface and library
6367 does not handle them.
6369 This change also changed a lot of structures, function naming etc.
6370 Most important change was that SilcClientWindow object was
6371 renamed to SilcClientConnection in the client library. Created
6372 also new file lib/silcclient/ops.h. Also added new files
6373 silc/local_command.[ch] and silc/client_ops.[ch].
6375 All these changes were made to make it easier for user interface
6376 designers to create what ever user interface for the SILC client
6379 It is also expected that the server will be moved to lib
6380 directory as well and SILC Server Library will be created;
6381 sometimes in the future.
6383 * Removed Local commands from lib/silccore/silccommand.h as
6384 they are application specific and new client library does not
6385 handle any of those anymore.
6387 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6388 old client implementation in silc/.
6390 * Added support for callback functions in SILC_LOG_* macros.
6391 Application can now set its own callbacks that will be called
6392 instead of using the default functions that will always print
6393 the debug messages to stderr (or stdout). Also, debugging can
6394 now be disabled by setting silc_debug to FALSE and re-enabled by
6395 setting it to TRUE. Note, that logging will still work even
6396 if debugging is disabled.
6398 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6399 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6400 silc_log_reset_debug_callbacks.
6402 * To enable debugging in silc client one must give now -d
6403 option on command line.
6405 * Changed silc_schedule_init to automatically allocate task queues
6406 if they are not allocated before calling it.
6408 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Added GMP 3.1 into math library.
6412 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6414 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6415 a channel in SILC network. The packet is used by servers and
6416 routers to notify other routers that user has left a channel.
6417 This little feature was missing until now. Added the feature
6418 to protocol specification as well.
6420 Added functions: silc_server_send_remove_channel_user and
6421 silc_server_remove_channel_user into server.[ch].
6423 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6424 lib/silccore/silcpacket.h. However, they are not implemented
6427 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Fixed joining to a channel and sending channel messages
6430 between server and router. The channel message sending should
6431 now work inside a cell.
6433 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6435 * Fixed the private message sending between server and router.
6436 The private message sending should now work inside a cell.
6438 * Added silc_server_replace_id into server.[ch] to replace
6439 existing ID in the SILC network.
6441 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6442 and silc_idlist_replace_server_id into idlist.[ch] in server.
6444 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Fixed the server to server connections. Server can again now
6447 connect to router. Router to router connections probably does
6450 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Added dynamic protocol registering support. Now protocols can
6453 registered and unregistered on the fly. Patch by cras.
6455 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6457 * Added lib/contrib directory to hold routines that some platforms
6458 don't have but are needed by SILC.
6460 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6461 into lin/contrib to provide getopt() and getopt_long() for
6462 those who don't have it.
6464 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * Added AWAY command to client. When away message is set and
6467 client receives a private message packet the client automatically
6468 replies to the sender with the away message.
6470 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6471 bug seemed to be the cause of recent problems when compiling
6474 * Added version detection support to SKE protocol specification
6475 and added the new changes to the SKE implementation as well.
6476 There were other minor changes in the SKE protocol as well.
6478 Many changes in lib/silcske/silcske.[ch] and in
6479 lib/silcske/payload.[ch].
6481 * Added ^U functionality, clear input line. Patch from cras.
6483 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Mainly small bugfixes on core library. Fixed some debugging
6486 logging and buffer overflow in silclog.c.
6488 * Updated config.sub and config.guess on the distribution tree.
6490 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Added command lagging support in server. Client may execute
6493 commands now only once in two seconds.
6495 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Optimized packet reception. MAC computation and checking is now
6498 also more optimized. A lot previously duplicated code is now
6499 used as generic by both client and server.
6501 * Fixed key pair generation in clientutil.c
6503 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * Added into lib/silccore/silcbufutil.[ch] new function;
6506 silc_buffer_realloc.
6508 * Moved generic packet sending/encryption functions to
6509 lib/silccore/silcpacket.[ch] from client and server. Some
6510 rewriting of the functions.
6512 * Moved all generic packet reception/decryption functions to
6513 lib/silccore/silcpacket.[ch] from client and server. The
6514 packet processing is now much cleaner in both client and server.
6515 These were major changes in both client and server.
6517 * Created many common functions in server to do packet sending.
6518 Previously code were duplicated a lot, this has been removed
6521 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6523 * Rewrote major parts of the ID cache system. Don't know
6524 whether it is better now or not but at least the API is more
6527 * Major rewrite on ID cache stuff on client because of the ID
6528 cache API changes. Added idlist.c to client.
6530 * Also major rewrite on ID cache stuff on server as well.
6531 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6532 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6533 in hand, instead they are all put into the ID cache system now.
6534 All server_idlist_* routines uses ID cache now instead of
6535 traversing its own lists (those lists does not exist anymore).
6536 SilcIDList though still exists. Also, SilcXXXEntry's are
6539 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6541 * Finally made the SKE implementation compliant to the protocol
6542 specification. All mp integers are now binary encoded as
6543 opposed being HEX encoded.
6545 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6548 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6549 functions: silc_[encode/decode]_pem. Also added function
6550 silc_encode_pem_file to PEM encode with newlines ('\n') for
6553 * SILC public keys are now encoded either PEM or binary. Same
6554 option is for private keys as well. By default private keys
6555 are binary encoded and public keys PEM encoded. Silly HEX
6556 encoding were removed.
6558 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6559 function to create fingerprints.
6561 * Fixed a bug in SHA1; does not change the original data anymore.
6563 * Partly implemented INFO command on client and server side.
6564 Fixed CLEAR command. Changes to SERVER command; show current
6565 server(s) when giving command without arguments. Added
6566 VERSION command to client.
6568 * Added check to server that unregistered connections cannot
6569 execute commands (unless it is specificly allowed).
6571 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * Fixed screen refresh.
6575 * Fixed channel joining bug from client. On some circumstances
6576 client tried to join to a channel it had already joined.
6578 * Added public key verification process into client's protocol.c.
6579 The client now verifies the public key from user and saves
6580 it into ~./silc/serverkeys/ directory.
6582 Added into: clientutil.[ch]: silc_client_verify_server_key.
6584 * Changed SKE protocol's silc_ske_initiator_finish function
6585 to accept callback function that verifies the received public
6586 key. Removed old silc_ske_verify_public_key function.
6588 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6591 silc_pkcs_private_key[_data]_set.
6593 * Made the password and public authentication more cleaner in
6594 server's protocol.c.
6596 * Removed historic and obsolete protocol `channel_auth' from
6597 both client and server.
6599 * Removed wrong way of sending command status messages from
6600 server to client in server's command.c. The old way violated
6601 protocol specification.
6603 Changes to silccore/silccommand.[ch]: removed
6604 silc_command_encode_status_payload -> not needed anymore,
6605 changed silc_command_encode_payload_va to accept extra
6606 argument on variable argument list. The argument type must
6607 now be provided to the function. Also, added new function:
6608 silc_command_encode_reply_payload_va which is same as
6609 normal command_encode_payload_va except command status type
6610 is provided as extra argument.
6612 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Added ~./silc directory handling. The directory includes the
6615 public and private keys for the client.
6617 Added silc_client_check_silc_dir, silc_client_create_identifier
6618 and silc_client_load_keys.
6620 * Implemented SILC protocol compliant public key. Added public
6621 and private key saving to and loading from files.
6623 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6624 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6625 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6626 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6627 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6629 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6630 silc_pkcs_load_[public/private]_key.
6632 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Added silc_server_get_route (route.[ch]) to get connection
6635 data for the fastest route for given ID.
6637 * Implemented INVITE command on client and server. The command
6638 were re-defined in the SILC Protocol Specification and the
6639 implementation now complies with the specification.
6641 * Implemented PING command on client and server.
6643 * Implemented NAMES command on client and server. The server side
6644 supports currently only normal server not router server yet.
6645 Some changes to NAMES definition in SILC protocol specification.
6647 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Implemented LEAVE command on client and server.
6651 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6652 again. This change was made to the protocol as well. Server
6653 should not violate the protocol specification anymore.
6655 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6657 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6658 was tested. SOCKS4 was not but should work anyway.
