1 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed silc_string_regexify list creation. Fixes bugs with
4 BAN and INVITE commands in server. The affected file is
5 lib/silcutil/unix/silcunixutil.c.
7 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Removed the command destructor entirely from the server's
10 command and command reply routines. It is not needed, and
11 its usage was buggy and caused crashes. Affected files are
12 silcd/command[_reply].[ch].
14 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
16 * Cancel protocol and NULL sock->protocol if timeout
17 occurred during protocol. Affected file silcd/server.c.
19 * Cancel protocol timeouts always before calling the final
20 callback, to assure that after final callback is called
21 no other state will be called for the protocol anymore.
22 Affected file silcd/protocol.c.
24 * Print error log if incoming connection configuration could
25 not be found. Affected file silcd/server.c.
27 * Fixed JOIN command to correctly save the founder mode
28 to the client on normal SILC server, when the channel
29 was created by the router. Affected file silcd/command.c.
31 * Fixed LIST command (hopefully) to send correct reply
32 packets. Affected file silcd/command.c.
34 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
36 * The silc_packet_receive_process now returns FALSE if the
37 read data was invalid packet, and TRUE if it was ok.
39 The server now checks that if unauthenticated connection
40 sends data and its processing fails the server will close
41 the connection since it could be a malicious flooder.
43 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
45 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
47 * Make sure the warning about error opening a log file is
48 printed only once and not everytime it fails (produces
49 too much useless log). Affected file lib/silcutil/silclog.c.
51 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
53 * Made the silc_server_daemonise() function more readable.
54 Affected file silcd/server.c.
56 * Pid file is now optional, the user may comment it out from
57 the config file. Removed define SILC_SERVER_PID_FILE, we
58 don't need a default any longer. Affected file
59 configure.in.pre, lib/Makefile.am.pre.
61 * Make some use of the pid file. The server now dies at startup
62 if it detects a valid pid file on his path. The server would
63 die anyway in this circumstance, because of the bind() failure.
64 Affected file silcd/silcd.c.
66 * No longer compiling lib/dotconf.
68 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
70 * Fixed JOIN command parsing not to crash. Affected file
71 lib/silcclient/command.c.
73 * Fied the NICK_CHANGE notify to add the new client entry
74 even it is resolved. This removes an <[unknown]> nick
75 thingy bug in the client. Affected file is
76 lib/silcclient/client_notify.c.
78 * Do not try to allocate 0 bytes (efence does not like it)
79 in lib/silccore/silccomand.c when encoding payload.
81 * Do not take IRCNICK as nickname in Irssi SILC client since
82 it is not possible to set nickname before hand connecting
83 the server (TODO has an entry about adding auto-nicking
86 * Changed the silc_server_command_pending to check whether
87 there already exists an pending entry with the specified
88 command, command identifier and pending callback. This is
89 to fix IDENTIFY and WHOIS related crashes that may register
90 multiple pending commands with same identifier. Affected
93 * Fixed the server to reconnect to the router even if it
94 was already reconnecting and EOF was received. This to
95 fix a possibility that the server wouldn't ever try to
96 auto-reconnect to the router. Affected file silcd/server.c.
98 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
100 * Fixed the server's password authentication to use the
101 length of the locally saved password, and not the one
102 sent in the packet. Affected file silcd/protocol.c.
104 * Fixed same password authentication problem in the
105 Authentication Payload handling routines in
106 lib/silccore/silcauth.c.
108 * Yet another password authentication problem fixed with
109 channel password handling in silcd/command.c.
111 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
113 * If first character of string in silc_parse_userfqdn is '@'
114 then do not parse it. Affected file is
115 lib/silcutil/silcutil.c.
117 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
119 * Fixed minor bug in IDENTIFY command reply sending, which
120 caused various weird problems during JOIN when it was
121 resolving names for users. Affected file silcd/command.c.
123 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
125 * Fixed the IDENTIFY command reply sending to chech better valid
126 clients. It was possible to send incomplete list of replies.
127 Affected file silcd/command.c.
129 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
131 * Added silc_client_command[s]_[un]register functions now to
132 dynamically register the commands in client library. Removed
133 the static table of commands. This allows the client library
134 to call commands without causing the application to know about
135 what commands library has called.
137 Removed the INFO command reply kludge to detect when the command
138 was called by library. Now library use its own command reply
139 function for INFO command.
141 Added function silc_client_command_call to call a command.
142 Application can use it to call command, not access the structure
145 Now all commands that are sent by the client library (not
146 explicitly sent by application) use own command reply functions.
148 Affected files around lib/silcclient/ and in
149 irssi/src/silc/core/.
151 * Fixed the WHOIS command reply sending to chech better valid
152 clients. It was possible to send incomplete list of replies.
154 Fixed the WHOIS and IDENTIFY to send the request to router
155 if normal server did not do it and did not find any results.
157 Affected file silcd/command.c.
159 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
161 * Moved the internal data from SilcClient context into its
162 own file, not accesible to application. Affected files
163 lib/silcclient/client.h and lib/silcclient/client_internal.h,
164 and other files in client library.
166 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
168 * Added doc/examples installation target in Makefile.am.pre.
171 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
173 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
174 commands the found client entry will be removed from the
175 cache, after notifying application about the error. Affected
176 file lib/silcclient/command_reply.c.
178 * Changed the /MSG to check for exact nickname user gave, and
179 not let `nick' match `nick@host' if it is only one found. Now,
180 user must type the exact nickname (like nick@host2) even if
181 there are no more than one same nicks found. This is to avoid
182 a possibility of sending nickname to wrong nickname since
183 `nick' could match `nick@host'. Affected file is
184 irssi/src/core/silc-servers.c.
186 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
188 * Do not print "you are now server operator" or similar when
189 giving /away command. Affected files are
190 irssi/src/silc/core/client_ops.c, silc-servers.h.
192 * Made the silc_server_command_pending_error_check to send
193 the same command reply payload it received back to the
194 original sender of the command. This way all arguments
195 that was received by the server will be received by the
196 client too. Affected file silcd/command.c.
198 * Added the silc_idcache_add to return the created cache entry
199 to a pointer. Affected file lib/silccore/silcidcache.[ch].
201 * Add global clients to expire if they are not on any channel.
202 This is because normal server will never know if they signoff
203 if they are not on any channel. The cache expiry will take
204 case of these entries. This is done by normal servers only.
205 The affected files are silcd/command_reply.c,
206 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
208 * If server receives invalid ID notification for WHOIS or
209 IDENTIFY and the ID exists in the lists, it is removed.
210 Affected file silcd/command_reply.c.
212 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
213 in client then client entry that it matches is searched and
214 the nickname is printed on the screen for user. Affected
215 file irssi/src/silc/core/client_ops.c.
217 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
219 * Use cache entry expire time in the LIST command reply to
220 purge old entries from the cache after the LIST command
221 reply has been received. This way we don't have non-existent
222 entries in the cache for too long. Affected file is
223 silcd/command_reply.c.
225 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
227 * If we are normal server, and we've not resolved client info
228 in WHOIS or IDENTIFY from router, and it is global client,
229 we'll check whether it is on some channel. If it is not
230 then we cannot be sure about its validity and will resolve it
231 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
232 file silcd/command.c.
234 * Search channel by name (if possible) rather than by ID
235 in IDENTIFY command's command reply. Affected file is
236 silcd/command_reply.c.
238 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
240 * Distribute to the channel passphrase in CMODE_CHANGE notify.
241 Updated specs and implemented it. Affected file silcd/command.c,
242 silcd/packet_send.c and silcd/packet_receive.c.
244 * Implemented the <founder auth> payload handling in the JOIN
245 command. If provided all conditions for channel joining
246 except requirement to provide correct passphrase can be
247 overrided by the channel founder. Updated the protocol specs.
248 Affected file silcd/command.c.
250 Added support for founder auth in JOIN command in client
251 library. Fixed the parsing of the JOIN command now to support
252 all options as they should be. The affected file is
253 lib/silcclient/command.c.
255 * Optimized the WHOIS and IDENTIFY commands to send the request
256 to router only if it includes nicknames or other names. If
257 they include only IDs then check the local cache first before
258 routing. Affected file is silcd/command.c.
260 * Added channels topic announcements. Affected file is
261 silcd/packet_receive.c and silcd/server.c.
263 * Fixed the silc_server_send_notify_topic_set to really destine
264 the packet to channel. Affected file silcd/packet_send.c.
266 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
267 library. Affected file lib/silcclient/client_notify.c.
269 * Added UMODE announcements. Affected file silcd/server.c.
271 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
273 * Memory leak fixes in:
275 lib/silcutil/silcsockconn.c
276 lib/silcske/silcske.c
279 lib/silccrypt/silcpkcs.c
280 lib/silccore/silccommand.c
281 lib/silccore/silcidcache.c
286 * ROBOdoc documented the lib/silcske/groups.h file and a
287 bit changed the interface for better.
289 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
291 * Update the client entry context in the ID cache after
292 nick change. Affected file lib/silcclient/command.c.
293 Fixes the CUMODE command when regaining founder privileges,
294 and a little WHOIS problem.
296 * Fixed silc_net_gethostbyname to correctly call the
297 inet_ntop. Affected file lib/silcutil/silcnet.c.
299 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
301 * Added IPv6 support checking to the configure.in.pre, added
302 also --enable-ipv6 option to override the check. Affected
303 file configure.in.pre.
305 * The silc_thread_create now calls the start function
306 directly if threads support is not compiled in. Removes
307 ugly #ifdef's from generic code. Affected files are
308 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
310 * Added silc_net_gethostby[name/addr]_async to asynchronously
311 resolve. Affected files are lib/silcutil/silcnet.[ch].
313 * Added support for rendering IPv6 based server, client and
314 channel IDs. Affected file lib/silcutil/silcutil.c.
316 * Added support for creating IPv6 based server IDs. Affected
317 file is silcd/serverid.c.
319 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
321 * Added silc_net_gethostby[addr/name] into the
322 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
323 routines. Added silc_net_is_ip[4/6]. Affected file is
324 lib/silcutil/unix/silcunixnet.c. All routines that take
325 address as argument now supports both IPv4 and IPv6 addresses.
327 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
329 * Fixed LIST command reply sending in server. Affected file
332 * Server now sends the kicker's client ID in the KICK notify
333 to the kicked client. Affected file silcd/command.c.
335 * The client library now parses the kickers client ID and
336 UI displays it. Affected files lib/silcclient/client_notify.c
337 and irssi/src/silc/core/silc-channels.c, module-formats.c.
339 * Made all payload parsing function prototypes consistent.
340 They all take now const unsigned char * and uint32 pair as
341 the payload data instead of SilcBuffer. Changes all around
342 the source tree. Other unsigned char* -> const unsigned char*
343 changes around the tree as well.
345 * Optimized SFTP client and server packet sending not to
346 allocate new buffer for each packet but to recycle the
347 first allocated buffer. Affected files are
348 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
350 * Optimized the SFTP client to use SilcList instead of
351 SilcDList for requests, because it is faster. Affected file
352 is lib/silcsftp/sftp_client.c.
354 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
355 into lib/silccore/silcid.[ch].
357 Renamed silcpayload.[ch] into silcargument.[ch].
359 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
361 * If client entry is deleted with active key agreement
362 session, abort the session.
364 The silc_client_abort_key_agreement now calls the completion
365 callback with new SILC_KEY_AGREEMENT_ABORTED status.
367 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
370 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
372 * Don't use __restrict in older GCC's. Affected file is
373 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
375 * silc_net_localhost now attempts to reverse lookup the
376 IP/hostname. Affected file lib/silcutil/silcnet.c.
378 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
379 command. It can be used to gain founder privileges at
380 the same time when joining the channel.
382 Defined that the SILC_NOTIFY_TYPE_KICKED send the
383 kicker's client ID as well. Updated protocol specs.
385 Defined that the server must send SILC_COMMAND_IDENTIFY
386 command reply with error status to client who sent
387 private message with invalid client ID.
389 Updated the protocol specification.
391 * Added silc_server_send_command_reply to send any
392 command reply. Affected file silcd/packet_send.[ch].
394 * Added silc_id_payload_encode_data to encode ID payload
395 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
397 * The server now send IDENTIFY command reply with error
398 status if client ID in private message is invalid. Affected
399 file silcd/packet_receive.c.
401 * Save the server key file with server's IP address in
402 the filename instead of hostname. The affected file is
403 irssi/src/silc/core/client_ops.c.
405 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
407 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
410 * Added libtool support for compiling shared objects in
411 lib/silcsim. Affected file configure.in.pre and
412 lib/silcsim/Makefile.am. Original patch by cras.
414 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>

419 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
421 * Fixed silc_client_channel_message to not try to decrypt
422 the message twice if it resolved the destination client
423 information. This could cause of dropping one channel
424 message. Affected file lib/silcclient/client_channel.c.
426 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Added silc_client_run_one into lib/silcclient/silcapi.h and
429 lib/silcclient/client.c. This function is used when the SILC
430 Client is run under some other scheduler, or event loop or
431 main loop. On GUI applications, for example this may be
432 desired to used to run the client under the GUI application's
433 main loop. Typically the GUI application would register an
434 idle task that calls this function multiple times in a second
435 to quickly process the SILC specific data.
437 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
439 * Fixed silc_server_drop() for dropping the supplementary
440 groups as well, this could cause a security hole on some
443 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
445 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

453 file silcd/command.c.
455 * Added INFO command reply handling to the Irssi SILC Client.
456 Affected file irssi/src/silc/core/client_ops.c.
458 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
460 * Fixed the silc_idcache_list_* routines to really support
461 the dynamic list. Fixes a crash. Affected file is
462 lib/silccore/silcidcache.c.
464 * Fixed the LIST command reply to really call LIST command's
465 pending callbacks. Affected file silcd/command_reply.c.
467 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
469 * Update conn->local_entry->nickname after giving NICK
470 command. Affected file lib/silcclient/command.c.
472 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
474 * Added the [pid] option to the silcd configuration file
476 Affected files: serverconfig.[ch] and silcd.c

481 Affected file silcd/command_reply.c.
483 * Fixed NICK commands pending callback registration.
484 Affected file lib/silcclient/command.c.
486 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
488 * Use ++server->cmd_ident when sending commands in server,
489 instead of random number. Affected file silcd/command.c.
491 * Fixed GETKEY command reply to call actually GETKEY pending
492 command callbacks. Affected file silcd/command_reply.c.
494 * A bit stricter check for nicknames. Check for same nickname
495 in NICK command also. Affected file silcd/command.c.
497 * Do not call INFO command everytime client ID changes, only
498 during first connecting. Affected file lib/silcclient/client.c.
500 * Set the new nickname only after successful command reply for
501 NICK command is returned by server. Affected file
502 lib/silcclient/command.c.
504 * Remove nicknames from nicklist during server_signoff notify.
505 Should fix /NAMES bit more. The affected file is
506 irssi/src/silc/core/silc-channels.c.
508 * Added `fingerprint' field to the SilcIDListData in the
509 silcd/idlist.h to hold the fingerprint of the client's
512 Send the fingerprint of the client's public key in WHOIS
515 Affected files silcd/command.c, and silcd/idlist.[ch].
517 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
518 create fingerprint from given data.
520 * Show the fingerprint of the client's public key in WHOIS.
521 Affected files irssi/src/module-formats.[ch] and
522 irssi/src/silc/core/client_ops.c.
524 * Format the multiple same nicknames also during JOIN and
525 NICK_CHANGE notifys. Affected file is
526 lib/silcclient/client_notify.c.
528 * Do not print error on screen for invalid private message
529 payload since it can come if someone is sending private
530 messages with wrong key. Affected file
531 lib/silccore/silcprivate.c.
533 * Fixed multiple concurrent /PING crash. Affected file
534 lib/silcclient/command.c.
536 * Changed the wrong ID encoding. All IP addresses must be
537 in MSB first order in encoded format. They were encoded
538 wrong and was in LSB format. Affected files are
539 silcd/serverid.c, lib/silcutil/silcutil.c.
541 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
543 * Call the `connect' client operation through the scheduler
544 in case of error. Affected file lib/silcclient/client.c.
546 * Call the `failure' client operation even if the error
547 occurred locally during a protocol. Affected file is
548 lib/silcclient/protocol.c.
550 * Added support of sending LIST command to router from normal
551 server. This way normal server can get list of all channels
552 in the network too. Fixed the channel list sending in the
553 server too. Affected files are silcd/command.c, and
554 silcd/command_reply.[ch].
556 * Added silc_server_update_channels_by_server and
557 silc_server_remove_channels_by_server. They are used during
558 disconnection of primary router and in backup router protocol.

560 silcd/server_backup.c.
562 * Fixed channel adding to global list in IDENTIFY command
563 reply in server. Affected file silcd/command_reply.c.
565 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
567 * If the incoming packet type is REKEY or REKEY_DONE process
568 that packet always synchronously. Fixes yet another MAC
569 failed error on slow (dialup) connections. Affected file
570 lib/silcclient/client.c and silcd/server.c.
572 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
574 * Call check_version SKE callback for initiator too. Affected
575 file lib/silcske/silcske.c.
577 * Implemented fix for security hole found in the SKE that was
578 fixed in the specification few days back; the initiator's
579 public key is now added to the HASH value computation.
580 Added backwards support for the old way of doing it too, for
581 old clients and old servers. Affected file is
582 lib/silcske/silcske.c.
584 * Enabled mutual authentication by default in SKE. If initiator
585 is not providing mutual authentication the responder will
586 force it. This will provide the proof of posession of the
587 private key for responder. The affected files are
588 lib/silcclient/protocol.c and silcd/protocol.c.
590 * Do not cache anymore the server's public key during SKE.
591 We do mutual authentication so the proof of posession of
592 private key is done, and if the server is authenticated in
593 conn auth protocol with public key we must have the public
594 key already. Affected file silcd/protocol.c.
596 * Added new global debug variable: silc_debug_hexdump. If
597 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
598 file lib/silcutil/silclog.[ch].
600 * Fixed compilation warning due to char * -> const char *.
601 Affected files lib/silcutil/silcnet.h, and
602 lib/silccore/silcauth.[ch].
604 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
606 * Fixed CMODE command when new channel key was created. If
607 the creation failed the old key was removed. Next time giving
608 same command would crash the server since the old key was
609 freed already. Affected file silcd/command.c.
611 * Fixed the silc_server_announce_get_channels to not crash
612 on reconnect. Affected file silcd/server.c.
614 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
616 * Added silc_log_set_debug_string function to set a regex
617 string to match for debug output. Only the function names,
618 or filenames matching the given debug string is actually
619 printed. This way it is possible to filter out those debug
620 strings that user is not interested in.
622 Fixed a bug in silc_string_regexify.
624 Affected files lib/silcutil/silclog.[ch], and
625 lib/silcutil/unix/silcunixutil.c.
627 * Changed the -d options in both server and Irssi SILC client
628 to take the debug string as argument. Affected files
629 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
631 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
633 * Added silc_hash_babbleprint to create a Bubble Babble
634 Encoded fingerprint. The encoding is developed by Antti
635 Huima (draft-huima-babble-01.txt), and it creates human
636 readable strings out of binary data. Affected file
637 lib/silccrypt/silchash.[ch].
639 * Print the babble print now in addition of fingerprint as well
640 in Irssi SILC client. Affected files are
641 irssi/src/fe-common/silc/module-formats.[ch],
642 irssi/src/fe-common/silc/core/client_ops.c.
644 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
646 * Fixed a security problem found in SKE. The initiator's
647 public key too is now added to the HASH hash value creation
648 which is signed by the responder to create the SIGN value.
649 This will prevent anyone in the middle to lie to the responder
650 about the initiator's public key. If this is done now, the
651 man in the middle will get caught. Updated the protocol
654 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
656 * Better installation directory handling. Configure module
657 paths and other paths automatically to example_silc* files
658 in doc/. A patch by toma.
660 * Fixed compiler warning from MPI library, and from SILC RNG.
663 * Added SILC_SERVER_PID_FILE to define the pid file for server.
664 It can be configured with ./configure. A patch by toma.
666 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
668 * Find correct make to use in prepare-clean. A patch by
669 toma. Affected file prepare-clean.
671 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
673 * Added irssi variables use_auto_addr, auto_bind_ip,
674 auto_bind_port and auto_public_ip.
676 * Changed the interface for silc_client_send_key_agreement
677 in lib/silcclient/silcapi.h
681 irssi/src/silc/core/silc-core.c
683 lib/silcclient/silcapi.h
684 irssi/src/silc/core/silc-channels.c
685 lib/silcclient/client_keyagr.c
688 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
690 * Added silc_pkcs_public_key_compare to compare two
691 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
693 * Check that the client who set the founder mode on the
694 channel is the same client that is giving the founder
695 mode to itself. It is done by comparing the saved public
696 key (it is saved even in the authentication is passphrase).
697 Affected file silcd/command.c.
699 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
701 * Do not process packet for disconnected socket connection.
702 Affected file lib/silccore/silcpacket.c.
704 * Process the DISCONNECT packet through scheduler in the
705 client library. Affected file lib/silcclient/client.c.
707 * Fixed the silc_client_packet_parse to not to increase
708 the packet sequence number if the conn->sock and the
709 current socket connection is not same. This can happen
710 for example during key agreement when the conn includes
711 multiple socket connections (listeners). Affected file
712 lib/silcclient/client.c.
714 * The sender of the file transfer request now provides also
715 the pointer (listener) for the key exchange protocol. If
716 the listener cannot be created then it sends empty key
717 agreement and lets the receiver provide the listener.
719 Added `local_ip' and `local_port' arguments to the
720 silc_client_file_send. If they are provided they are used,
721 if not then it will attempt to find local IP address, if
722 not found or bind fails then the remote client will provide
725 Affected files are lib/silcclient/client_ftp.c and
726 lib/silcclient/silcapi.h.
728 * Extended the FILE SEND command to support defining the
729 local IP and port for key exchange listener. They are
730 optional. Affected file irssi/src/silc/core/silc-servers.c.
732 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
734 * Defined to WHOIS command reply the sending of fingerprint
735 of the client's public key (if the proof of posession of the
736 corresponding private key is verified by the server).
737 Updated to the protocol specification.
739 * Added support of receiving the client's public key's
740 fingerprint in command reply in client library. Affected
741 file is lib/silcclient/command_reply.c, and
742 lib/silcclient/idlist.[ch].
744 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
746 * Do not send over 128 chars long nickname to the server
747 in NICK command. Affected file lib/silcclient/command.c.
749 * Do not send over 256 chars long channel names to the server
750 in JOIN command. Affected file lib/silcclient/command.c.
752 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
754 * Assure that silc_server_close_connection cannot be called
755 twice for same socket context. Affected file is
758 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
760 * Send error message to application if opening file for
761 writing during file transfer fails. Affected file is
762 lib/silcclient/client_ftp.c.
764 Remove all file transfer sessions for a client that we're
765 removing from ID cache.
767 Affected file is lib/silcclient/client_ftp.c.
769 * Fixed silc_net_addr2bin to return correct address. Affected
770 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
772 * Fixed file transfer session removing on signoff notify.
773 Affected file irssi/src/silc/core/silc-servers.c.
775 * Added the SilcClientFileError to be returned in the monitor
776 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
777 Affected file lib/silcclient/silcapi.h.
779 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
781 * Fixed a crash in silc_client_ftp_free_sessions and
782 silc_client_ftp_session_free_client. Affected file
783 lib/silcclient/client_ftp.c.
785 * Added `disabled' field in the SilcChannelEntry in the server
786 to indicate if the server entry is disabled. Affected file
787 silcd/idlist.h, silcd/command[_reply].c.
789 * SILC server adds now /var/run/silcd.pid everytime it is
790 started. Affected file silcd/silcd.c.
792 * Added silc_server_packet_send_clients to send a packet to
793 the provided table of client entries. Affected file
794 silcd/packet_send.[ch].
796 * Fixed a crash in client resolving in client_prvmsg.c in
797 client library. Affected file lib/silcclient/client_prvmsg.c.
799 * Do not actually remove the client directly from ID cache
800 during SERVER_SIGNOFF, but invalidate it. This way we
801 preserve the WHOWAS info for the client. Affected file
804 * Fixed SERVER_SIGNOFF notify handling in the server. The
805 server is now able to process incoming SERVER_SIGNOFF notify
806 for a server that it doesn't even know about. It will remove
807 the clients provided in the notify. Affected file
808 silcd/packet_receive.c.
810 * Check for partial packet in data queue after every packet that
811 was found from the queue. Return and wait for more data if
812 there is partial data in queue. Affected file is
813 lib/silccore/silcpacket.c.
815 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
817 * Added SilcClietFileError enum to indicate error in
818 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
819 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
820 Affected files lib/silcclient/silcapi.h and
821 lib/silcclient/client_ftp.c.
823 * Check that newsize in silc_buffer_realloc is larger than
824 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
826 * Added better monitor of file transfers. It now monitors
827 key agreement protocol during the file transfer too. Added
828 error reporting too. Affected files
829 irssi/src/silc/core/silc-servers.c,
830 irssi/src/fe-common/silc/module-formats.[ch].
832 * Wrote a help file for FILE command.
834 * Added silc_rng_global_get_byte_fast to get not-so-secure
835 random data as fast as possible. Random data is read from
836 /dev/urandom if available and from the SILC RNG if not
837 available. It is used in padding generation. Affected file
838 lib/silccrypt/silcrng.[ch].
840 * All packets in client library are now processed synchronously.
841 Optimized packet processing a lot. Affected file
842 lib/silcclient/client.c.
844 * All server connection packets are processing synchronously
845 now in server, to optimize packet processing. Affected file
848 * Include files are installed now only in Toolkit distribution
849 if make install is given. Affected files: all Makefile.am's.
851 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
853 * Assure that silc_client_notify_by_server_resolve does not
854 resolve the client information multiple times. If it cannot
855 be found by the first it cannot be found at all. Affected
856 file lib/silcclient/client_notify.c.
858 * Fixed WHOWAS command reply calling. Affected file
859 lib/silcclient/command_reply.c.
861 * Removed all references to silc_idlist_get_client from the
862 Irssi SILC client since that call is internal call used by
863 the library. The Irssi SILC client will use now client
864 retrieval functions found in silcapi.h.
866 * Fixed a bug in resolving nickname info before sending
867 private message. It used freed memory. Affected file
868 irssi/src/silc/core/silc-servers.c.
870 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
872 * Assure my_channels statistics cannot go negative in server.
873 Affected files silcd/server.c, silcd/server_util.c.
875 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
877 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
879 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
881 * Win32 Toolkit changes. Affected files
882 win32/silc.dsw, win32/libsilc/libsilc.def,
883 win32/libsilcclient/libsilc.def,
884 lib/silcutil/silcutil.c, and
885 lib/sftp/sftp_fs_memory.c.
887 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
889 * Added silc_net_localip to return local host's IP address.
890 Affected file lib/silcutil/silcnet.[ch].
892 * If key exchange or rekey protocol is active for a connection
893 parse all packets syncronously since there might be packets
894 in packet queue that we are not able to process without first
895 processing packets before them. Affected file silcd/server,
896 lib/silcclient/client.c.
898 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
899 whether library should continue processing the packet.
900 Affected file lib/silccore/silcpacket.h.
902 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
903 SilcSFTPMonitorData to SFTP server to monitor various
904 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
905 lib/silcsftp/sftp_server.c.
907 * Added silc_file_size to return file size. Affected file
908 lib/silcutil/silcutil.[ch].
910 * Implemented the file transfer support for the client library.
911 Added preliminary support for simple client to client one-file
912 transmission. Affected file lib/silcclient/client_ftp.c,
913 lib/silccilent/client.[ch].
915 * Added new local command FILE to the Irssi SILC Client.
916 It is used to perform the file transfer. It has subcommands
917 SEND, RECEIVE, SHOW and CLOSE. Affected files
918 irssi/src/silc/core/client_ops.c,
919 irssi/src/silc/core/silc-server.[ch].
921 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
923 * Relay the SILC_PACKET_FTP in the server. Affected files
924 silcd/server.c and silcd/packet_receive.c.
926 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
928 * Renamed silc_file_read and silc_file_write to functions
929 silc_file_readfile and silc_file_writefile. Added function
930 silc_file_open and silc_file_close. Affected files
931 lib/silcutil/silcutil.[ch].
933 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
935 * Resolve the client info when received private message or
936 channel message for a client which nickname we don't know.
937 Affected files lib/silcclient/client_prvmsg.c and
938 lib/silcclient/client_channel.c.
940 * Do not crash in /KEY if client is not connected. Affected
941 file irssi/src/silc/core/silc-channels.c.
943 * Added SilcClientStatus field to the SilcClientEntry in the
944 lib/silcclient/idlist.h.
946 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
947 is incomplete and is being resolved, it won't be resolved
950 Make sure also that USERS command reply does not resolve
951 twice information. Affected file is
952 lib/silcclient/command_reply.c.
954 Make sure that silc_client_get_clients_by_list does not
955 resolve twice same information.
957 * Check for valid client->id in the silc_server_free_client_data.
958 Affected file silcd/server.c.
960 * Fixed /GETKEY nick@server not to crash if the server entry
961 is not found. Affected file lib/silcclient/command.c.
963 * Fixed the silc_server_check_cmode_rights to check the
964 requested modes correctly. Affected file silcd/command.c.
966 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
968 * Better checks for non-printable chars in nick added.
969 Affected file silcd/command.c.
971 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
973 * Call the silc_server_udpate_servers_by_server in the
974 primary router that comes back online in the backup resuming
975 protocol. Otherwise it routes packets wrong. Affected file
976 silcd/server_util.[ch], silcd/server_backup.c.
978 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
980 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
981 lib/silcutil/silcbuffmt.[ch].
983 * Redefined the SILC packet header to include the padding
984 length. Affected file lib/silccore/silcpacket.[ch].
986 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
987 length for maximum padding up to 128 bytes). Affected
988 file lib/silccore/silcpacket.h.
990 * Removed all backwards support for old 0.5.x MAC thingies.
991 The SILC packet header change makes it impossible to be
992 backwards compatible.
994 * Send the ENDING packet with timeout in the backup resuming
995 protocol. This is to assure that all routers has connected
996 to the primary router. Affected file silcd/server_backup.c.
998 * Changed the RNG to take the first IV from random data. It
999 used to take it from zero actually. Changed the RNG also
1000 to use /dev/urandom during session. /dev/random is used
1001 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1003 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1005 * Changed the SILC packet header to have the first two bytes
1006 (the packet length) encrypted. Affected files aroung the
1007 code tree, lib/silccore/silcpacket.[ch]. Removed the
1008 SilcPacketCheckDecrypt callback. It is not needed anymore
1009 since the silc_packet_receive_process will determine now
1010 whether the packet is normal or special.
1012 * Implemented the unidirectional MAC keys. Affected files
1013 lib/silcske/silcske.c, silcd/protocol.c and
1014 lib/silcclient/protocol.c.
1016 * Implemented the packet sequence number to the MAC computation.
1017 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1018 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1019 lib/silcclient/protocol.c.
1021 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1023 * Allow backup router to announce servers. All servers
1024 announced by backup router are added to the global list
1025 automatically. Update hte server's socket to our primary
1026 router also when backup router announces a server.
1027 Affected file silcd/packet_receive.c.
1029 * Do not update the client->router in the function
1030 silc_server_udpate_clients_by_server if the client is on
1031 global list. We might fail to find any specific server
1032 for locally connected clients and local cell clients. They
1033 should still use the `from' and not `to' as client->router.
1034 This fixes backup router resuming protocol. Affected file
1035 silcd/server_util.c.
1037 * Decrease channel statistics count only if the channel
1038 deletion worked. Affected files are silcd/server.c and
1039 silcd/server_util.c.
1041 * Added silc_server_update_servers_by_server to update origin
1042 of all server entries. Used during backup router protocol.
1043 Affected files silcd/server_util.[ch], silcd/server.c. and
1044 silcd/backup_router.c.
1046 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1047 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1048 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1049 lib/silccrypt/silchmac.c.
1051 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1053 * Assure that router cannot reroute the same channel message
1054 to the sender. Affected file silcd/packet_receive.c.
1056 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * Made better checks that the channel message is not sent
1059 to the router it came from. Affected file is
1060 silcd/packet_send.c. Fixed memory leak too.
1062 * Announce informations for incoming router connection, but
1063 only after checking if it is replaced by backup router.
1064 Affected file silcd/packet_receive.c.
1066 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1068 * Fixed the backup resuming protocol to work in multiple
1069 router environment. Affected file silcd/server_backup.c.
1071 * Route packet only to one router in the function
1072 silc_server_packet_send_to_channel. Affected file is
1073 silcd/packet_send.c.
1075 * Fixed silc_server_send_notify_dest to set the broadcast
1076 flag. Fixed the silc_server_send_notify_topic to actually
1077 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1078 Affected file silcd/packet_send.c.
1080 * Changed the SFTP Filesystem interface. Changed the
1081 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1082 the filesystem operation function. The SilcSFTPFilesystem
1083 is now a context that is allocated by all filesystem allocation
1084 functions and it already includes the operations structure
1085 and filesystem specific context. It is given as argument
1086 now to the silc_sftp_server_start. This made the interface
1087 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1088 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1090 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1092 * Changed the backup router adding and getting interfaces
1093 in the server. The router that will be replaced by the
1094 specified backup router is now sent as argument. Affected
1095 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1098 * Added silc_net_addr2bin_ne to return the binary form of
1099 the IP address in network byte order. Affected files
1100 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1102 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1104 * Check for existing server ID in silc_server_new_server
1105 and in silc_server_connect_to_router_final and remove the
1106 old entry if it exists. Affected file silcd/packet_receive.c,
1109 * Send the channel message always to only one router, either
1110 in upstream or downstream. Affected file is
1111 silcd/packet_send.c.
1113 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1115 * Wrote the definition of the backup resuming protocol to the
1116 protocol specification.
1118 * Removed one redundant channel key generation from normal
1119 server during joining procedure. Removed one redundant
1120 channel key sending from server to router during joining
1121 procedure. Affected file silcd/command.c.
1123 * Made minor bugfixes to the backup router resuming protocol.
1124 Affected file silcd/server_backup.c, server.c.
1126 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1128 * Added --disable-asm configuration option. Affected files
1129 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1132 * Implemented the backup resuming protocol that is used to
1133 resume the primary router position in the cell after the
1134 primary router comes back online. Affected files
1135 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1136 and silcd/server_util.[ch].
1138 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * Sleep two (2) seconds after sending QUIT command to server.
1141 Affected file lib/silcclient/command.c.
1143 * Assure that if outgoing data buffer is pending do not force
1144 send any data. Affected file silcd/packet_send.c.
1146 * Assure that if outgoing data buffer is pending do not force
1147 send any data. Affected file lib/silcclient/client.c.
1149 * Implemented the backup router support when the primary router
1150 goes down. The servers and routers can now use the backup
1151 router as new primary router without loosing connectivity.
1153 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1155 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1156 in the server to indicate disabled entry. All data read
1157 from the connection will be ignored and no data is sent
1158 for entry that is disabled. Affected files are
1159 silcd/idlist.h, silcd/server.c.
1161 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1163 * Created SFTP client and server test programs in the
1164 lib/silcsftp/tests directory.
1166 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Implemented memory filesystem (virtual filesystem) for
1169 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1172 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1174 * Implemented the SFTP (SSH File Transfer Protocol) to the
1175 lib/silcsftp. It includes SFTP client and SFTP server
1178 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1180 * Moved lib/silccore/silcprotocol.[ch] to the
1181 lib/silcutil library.
1183 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1184 take variable argument list pointer as argument. Affected
1185 file lib/silcutil/silcbuffmt.[ch].
1187 * Added silc_buffer_set function that is used to set data
1188 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1189 Affected file lib/silcutil/silcbuffer.h.
1191 * Changed various routines in the core library to use the new
1192 silc_buffer_set instead of allocating new buffer only for
1195 * Added 64-bit value formatting and unformatting support to the
1196 silc_buffer_[un]format routines. Affected file is
1197 lib/silcutil/silcbuffmt.[ch].
1199 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1200 to includes/bitmove.h.
1202 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * Fixed channel user mode saving in client library. Affected
1205 file lib/silcclient/command[_reply].c.
1207 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1209 * Defined the file transfer to the SILC Protocol. Added
1210 new packet type SILC_PACKET_FTP and defined File Transfer
1211 Payload. The mandatory file transfer protocol is SFTP
1212 (SSH File Transfer Protocol). Affected file in addition
1213 of the internet draft is lib/silccore/silcpacket.h.
1215 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1216 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1217 is used as part of backup router protocol when the primary
1218 router of the cell is back online and wishes to resume
1219 the position as primary router.
1221 * Redefined the MAC generation keys in the protocol. The
1222 same key is not used anymore in both direction. Both
1223 direction will now use different keys for sending and
1224 receiving. This fixes a potential security flaw. This
1225 change causes incompatibilities in the protocol.
1227 * Redefined also the MAC computation from the packet.
1228 An packet sequence number is now added to the MAC
1229 computation. This prevents possible replay attacks against
1230 the protocol. This change too causes incompatibilities
1233 Added `sequence' field to the SilcPacketContext to hold
1234 the current sequence number for the packet.
1236 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1238 * Added `created' field to the SilcIDListData in the file
1239 silcd/idlist.h to indicate the time when the entry was
1242 * Added `created' field to the SilcChannelEntry too. Affected
1243 file silcd/idlist.h.
1245 * Added `creation_time' aguments to all the announcement functions
1246 in the server. If it is provided then only the entries that
1247 was created after the provided time frame are actually
1248 announced. Affected file silcd/server.[ch].
1250 * The protocol says that the Channel ID's IP address must be
1251 based on the router's IP address. Added check for this in
1252 the silc_server_new_channel when processing incoming New Channel
1253 Payload. Affected file silcd/packet_receive.c.
1255 * Print out the correct version with --version in SILC client.
1256 Affected file irssi/src/silc/core/silc-core.c.
1258 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1260 * Fixed WHOWAS command to check for completnes of the client
1261 entry always, not just when the command is coming from client.
1262 Affected file silcd/command.c.
1264 * Added new function silc_server_packet_queue_purge to purge the
1265 outgoing data queue to the network. After the function returns
1266 it is guaranteed that the outgoing packet queue is empty.
1267 Affected file silcd/packet_send.[ch].
1269 * Purge the outgoing packet queue in the rekey protocol's final
1270 callback to assure that all rekey packets go to the network
1271 before quitting the protocol. Affected file silcd/server.c.
1273 * Added silc_client_packet_queue_parse as similar function as
1274 in server to the client library. The affected file is
1275 lib/silcclient/client.c.
1277 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1279 * Splitted silcd/server.c and created silcd/server_util.[ch]
1280 for utility functions.
1282 * Added new socket flag SILC_SF_DISABLED to indicate that the
1283 connection is open but nothing can be sent to or received from
1284 the connection. Affected file lib/silcutil/silsockconn.[ch].
1285 The checking for disabled socket is checked in the low level
1286 silc_socket_write and silc_socket_read functions.
1288 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1290 * Allow only nicknames and channel names that fits into the
1291 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1293 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * When processing JOIN command reply in server check that if
1296 the channel exists in our global list we'll move it the local
1297 list. Affected file silcd/command_reply.c.
1299 * Fixed the check whether client is joined on the channel already
1300 in JOIN command. Affected file lib/silcclient/command.c.
1302 * Fixed the JOIN command reply to check whether the channel
1303 already exists. Affected file lib/silcclient/command_reply.c.
1305 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1307 * Added silc_ske_status_string to map the SKE error numbers
1308 to readable strings. The affected files are
1309 lib/silcske/silcske[_status].[ch].
1311 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * Do not show the private channels on the WHOIS channel list
1314 as it is not allowed by the protocol. The affected file is
1317 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Assure that the packet length digged from the actual packet
1320 is something sensible in the silc_packet_decrypt_rest_special
1321 in lib/silccrypt/silcpacket.c.
1323 * Free and NULL the allocated pointer in silc_hmac_alloc if
1324 the HMAC allocation fails. The affected file is
1325 lib/silccrypt/silchmac.c.
1327 * Print the selected security properties to the log files in
1328 the server. Affected file silcd/protocol.c.
1330 * Add SKE's reference counter even if calling the completion
1331 callback manually. Otherwise it goes negative, although it
1332 does not cause any problems. The affected file is
1333 lib/silcske/silcske.c.
1335 * Remove the client entry with short timeout after giving the
1336 KILL command. Affected file lib/silcclient/command.c.
1338 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1339 case all found clients are already disconnected (WHOWAS would
1340 found them) in the server. Affected file silcd/command.c.
1342 * Update the last_receive (time of last data received) to be
1343 updated only when received private or channel message so that
1344 the idle time showed in WHOIS makes more sense.
1346 * Added boolean field `valid' in to the SilcClientEntry in the
1347 client library to indicate whether the entry is valid or not.
1348 This fixes the nickname change bug on channel when changing
1349 the nickname to be same than the old (like nick to Nick) the
1350 nickname formatter doesn't set the new nick anymore to Nick@host.
1351 Affected file lib/silcclient/idlist.[ch].
1353 * Now actually fixed the nickname changing on disconnection.
1354 Added new function silc_change_nick to the Irssi SILC Client.
1355 Affected file irssi/src/silc/core/client_ops.c,
1356 irssi/src/silc/core/silc-nicklist.[ch].
1358 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1360 * Check that the public key exists in the GETKEY command before
1361 trying to encode it. Affected file silcd/command.c.
1363 * Print some notifications on received public keys with GETKEY
1364 command in the Irssi SILC Client. Affected files are
1365 irssi/src/fe-common/silc/module-formats.[ch],
1366 irssi/src/silc/core/client_ops.c.
1368 * Use IDENTIFY command to resolve the server information in the
1369 GETKEY command instead of INFO command. Affected file
1370 lib/silcclient/command.c.
1372 * All command reply functions in the client library now calls
1373 the pending command reply callbacks even if an error has
1374 occurred. The server has done this a long time and now it was
1375 time to move the client library to this as well. Now all
1376 errors can be delivered back to the pending command reply
1377 callbacks if necessary. Affected files are
1378 lib/silcclient/command[_reply].[ch].
1380 * Change the nickname on disconnection back to the username
1381 because in reconnect the server will enforce it to it anyway.
1382 Affected file irssi/src/silc/core/silc-servers.c.
1384 * Fixed a config file parsing bug in the Irssi SILC client.
1385 Affected file irssi/src/silc/core/clientconfig.c.
1387 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1389 * When printing the channel mode on JOIN, verify that the
1390 channel key and channel's HMAC are valid. Affected file
1391 irssi/src/silc/core/client_ops.c.
1393 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1395 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1396 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1397 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1399 * Removed channel key rekey task deleting from the function
1400 silc_server_save_channel_key. Affected file silcd/server.c.
1401 Added explicit timeout task context instead that is used to
1402 delete the task if we are registering a new task before the
1403 new task has elapsed.
1405 * When channel key rekey occurs the client library now saves
1406 the old channel key for a short period of time (10 seconds) and
1407 is able to use it in case some is still sending channel
1408 messages encrypted with the old key after the rekey. Affected
1409 file lib/silcclient/[idlist.h|client_channel.c].
1411 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Added check to the silc_server_new_id_real to not accept
1414 new ID if it is the sender's own ID. Affected file is
1415 silcd/packet_receive.c.
1417 * Assure that we do not announce ourself or the one we've
1418 sending our announcements when we're router and are announcing
1419 servers to our primary router. Affected file silcd/server.c.
1421 * Fixed silc_server_command_identify_check_client to assemble
1422 correct WHOIS packet. It send corrupted WHOIS packet and
1423 caused problem with router to router connections. Affected
1424 file silcd/command.c.
1426 Fixed also silc_server_command_whois_check the same way
1427 as for the IDENTIFY command.
1429 * Added new SilcIDListStatus to the server in the SilcIDListData
1430 structure. The status now includes the current status of
1431 the entry (like registered, resolved etc.). Affected file
1432 silcd/idlist.[ch]. Defined a bunch of different status types
1433 as well. This replaced the old boolean registered field as well.
1435 Added resolve_cmd_ident field to the SilcClientEntry structure
1436 too so that if the entry is for example being resolved so
1437 another command may attach to the same pending command reply
1438 without requiring to resolve the same entry again. This concept
1439 should optimize the WHOIS and the IDENTIFY resolving under
1440 heavy load by taking away unnecessary resolving for entries
1441 that are being resolved already.
1443 Added support for adding multiple pending commands for one
1444 command idenfier. Affected file silcd/command[_reply].[ch].
1446 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1447 before deleting the data. Otherwise the hash table will have
1448 freed data in comparison functions. Affected file is
1449 silcd/command_reply.c.
1451 * Fixed silc_idlist_replace_client_id to add the new entry to
1452 the cache with NULL nickname. Otherwise there will be invalid
1453 memory as the nickname after the nickname is freed. Affected
1454 file silcd/packet_receive.c.
1456 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1457 saved into wrong slots because the previous number of entries
1458 was not taken into account. Affected file silcd/idlist.c.
1459 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1461 * If we are router and we receive JOIN notify to a channel that
1462 does not have any users then notified client is marked as the
1463 channel founder, as it is it. The affected file is
1464 silcd/packet_receive.c
1466 * Added to the extended hash table API's table_del_*ext functions
1467 the destructor as argument too, so that the caller can decide
1468 which destructor to use or whether to use destructor at all.
1469 Affected file lib/silcutil/silchashtable.[ch].
1471 * Fixed ID Cache purging. It actually deleted the entries from
1472 the hash table after the data was freed. The hash table ended
1473 up comparing freed memory. The affected file is
1474 lib/silccore/silcidcache.c.
1476 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Fixed Irssi SILC client's KILL command's HELP syntax.
1480 * The USERS command now resolves the detailed user information
1481 if the userinfo field is missing. Affected file is
1482 lib/silcclient/command_reply.c.
1484 * Do not print error in silc_file_read if the read file does
1485 not exist. Just silently return NULL. Affected file is
1486 lib/silcutil/silcutil.c.
1488 * Fixed the silc_log_output to not wine about NULL filename
1489 and to not create some bogus " " filename. Affected file is
1490 lib/silcutil/silclog.c.
1492 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1494 * Fixed various printing bugs on the user interface in the
1495 Irssi SILC Client. Minor changes that were forgotten from
1498 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1500 * Fixed the configure.in.pre and the compilation and distribution
1501 environment to support the new autoconf 2.52. That version is
1502 now required to compile the CVS trunk.
1504 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1506 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1507 to generally parse user@fqdn format strings. Affected file
1508 lib/silcutil/silcutil.c.
1510 * Added nickname_format and nickname_force_format fields to the
1511 SilcClientParams structure. The first one defines the format
1512 for the nicknames that the library will enforce if the receives
1513 multiple same nicknames. The second one is boolean value and
1514 can be used to force the library to always enforce the format
1515 to the nicknames regardles whether there are multiple nicknames
1516 or not. This configurable formatting was employed to flexibly
1517 support accessing multiple nicknames from the user interface.
1518 The userinterface can now set the nicknames to what ever format
1519 they prefer. Affected file lib/silcclient/silcapi.h.
1521 Added function silc_client_nickname_format to the file
1522 lib/silcclient/idlist.c. It performs the nickname formatting.
1524 Added new field `hostname´ to the SilcClientEntry context.
1525 It holds the hostname of the client. Affected file is
1526 lib/silcclient/idlist.h.
1528 * Irssi SILC Client sets the nicknames in nick@hostn format.
1529 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1530 irssi/src/silc/core/silc-core.c.
1532 The WHOIS printing now also shows both the real nickname and
1533 the formatted nickname so that user knows how to access the
1534 user if there are multiple same nicknames cached. Affected
1535 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1536 printing formatting too to take the hostname now as a separate
1537 argument. The Affected file is
1538 irssi/src/fe-common/silc/modules-formats.[ch].
1540 * Changed the silc_client_get_clients_local to accept the formatted
1541 nickname as argument. It accepts the real nickname too but the
1542 formatted nickname can be used to find the true entry from
1543 multiple entries. Affected file lib/silcclient/silcapi.h and
1544 lib/silcclient/idlist.c.
1546 * Added nickname_format_parse field to the SilcClientParams.
1547 It is a callback function provided by the application to parse
1548 the nickname out of the formatted nickname string. The library
1549 calls it to get the nickname from the formatted string. Since
1550 the application generally knows better the format of the nickname
1551 string it parses it instead of the library, even though library
1552 encodes the formatted string. If the callback function is not
1553 provided then the library will use the string as is. The
1554 affected file is lib/silcclient/silcapi.h.
1556 * All the nickname strings passed to the client library in
1557 commands are now expected to be formatted nickname strings.
1558 If the command does not support the formatted nickname string
1559 it will assume that the sent string is the actual nickname.
1560 Affected file lib/silcclient/command.c.
1562 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1564 * Added public key authentication support to OPER and SILCOPER
1565 commands in the client library. Affected file is
1566 lib/silcclient/command.c.
1568 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1570 * Changed the get_auth_methdod client operation to be asynchronous.
1571 It can be async if the application resolves the authentication
1572 method from the server during the negotiation. Added new
1573 SilcGetAuthMeth completion callback that the application will
1574 call after resolving the authentication method.
1576 Added function silc_client_request_authentication_method that
1577 the application can use to resolve the authentication method
1578 from the server. Added also SilcConnectionAuthRequest callback
1579 that the library will call after the server has replied. The
1580 application can call this function if it does not know the
1581 current authentication method.
1583 Affected files are lib/silcclient/client.c and
1584 lib/silcclient/silcapi.h.
1586 * The Irssi SILC client now automatically resolves the authentication
1587 method incase any configuration information is not present (and
1588 currently there never is). The affected file is
1589 irssi/src/silc/core/client_ops.c.
1591 * Fixed public key authentication from the client library.
1592 Affected file lib/silcclient/protocol.c. Changed also the
1593 protocol specification about the public key authentication in
1594 the connection authentication protocol. The actual data to be
1595 signed is now computed with a hash function before signing.
1597 * Fixed the public key authentication from the server as well.
1598 Affected file silcd/protocol.c.
1600 * Removed the mlock()'s from the memory allocation routines.
1601 Affected file lib/silcutil/silcmemory.c. The ./configure does
1602 not check anymore for the mlock(). Affected file is
1605 * Fixed USERS command in server to allow the execution of the
1606 command for private and secret channels if the client sending
1607 the command is on the channel. Affected file silcd/command.c.
1609 * Fixed silc_client_get_clients_local to return the clients
1610 count correctly. It could return wrong value. Affected file
1611 lib/silcclient/idlist.c.
1613 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1616 types. The assembler optimizations seemed not to like 64-bit
1617 data types. The assmebler optimizations thus are now enabled
1618 also for BSD systems as opposed to only enable them for Linux.
1620 * Do not check for threads at all on BSD systems. Affected
1621 file configure.in.pre.
1623 * Removed -n and -h options from the Irssi SILC Client since
1624 they are not used in silc.
1626 * Fixed the prime generation to assure that the first digit
1627 of the generated random number is not zero since our conversion
1628 routines does not like number strings that starts with zero
1629 digit. If zero digit is seen the random number is regenerated.
1630 This caused some corrupted RSA keys when the zero first digit
1631 was met. Affected file lib/silcmath/silcprimegen.c.
1633 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1635 * Fixed WIN32 configuration in the ./configure script.
1636 Fixed to include xti.h on environments that has it.
1637 Patches by Carsten Ilchmann and andrew.
1639 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Changed the silc_id_create_client_id to be collision
1642 resistant. It is now assured that there cannot be created
1643 two same client ID's. I suspect that some weird bugs in
1644 the server were actually caused by duplicate Client IDs.
1645 Affected file silcd/serverid.[ch]. A router receiving
1646 new ID now also assures and informs the sending server
1647 if the ID caused collision.
1649 * Changed the silc_id_create_channel_id to also assure that
1650 there are no collisions.
1652 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1654 * Statement about ignoring the Mutual Authentication flag when
1655 performing rekey with PFS was a bit misleading. It is ignored
1656 if it was set in the initial negotiation, it cannot be even
1657 set in the rekey. Fixed in the ke-auth draft. Started the
1658 new versions of the protocol drafts in the doc/.
1660 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1662 * Fixed a bug in silc_client_command_identify_save when saving
1663 new channel information. The channel name was no duplicated
1664 and caused crash on exit. Affected file is
1665 lib/silcclient/command_reply.c.
1667 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1669 * Fixed the getkey command handling in the server. Send just
1670 empty OK reply to the sender if the key could not be fetched
1671 (but everything else was ok, like the key just was not available).
1672 Changed the public key parameter to optional in the protocol
1673 specs so that empty OK reply can be sent. Affected file
1676 Added a message to Irssi SILC client to tell to user if the
1677 server did not return a public key.
1679 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1681 * Fixed a channel key regeneration bug. It registered new
1682 timeout tasks exponentially until all system resources were
1683 used. Affected file silcd/server.c.
1685 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1687 * Added the SILC Document generator to the scripts/silcdoc.
1688 It can be used to generate the Toolkit Reference Manual out
1689 of the source tree. Internally it will also use the RoboDoc
1690 generator now imported in util/robodoc.
1692 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * Added couple of return's in rekey protocol if error orccurred
1695 during the protocol. The execution must be terminated.
1696 Affected file silcd/protocol.c. Also, terminate the protocol
1697 always with timeout.
1699 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * The client's Client ID was created initally from the wrong
1702 nickname (it could have been in format nick@host) in the
1703 silc_server_new_client. Affected file silcd/packet_receive.c
1705 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1707 * Added some SILC_LOG_ERROR's to various error conditions
1708 if client could not be added to ID cache. Affected files
1709 silcd/packet_receive.c and silcd/server.c.
1711 * When client's sock->user_data is freed, NULL also the
1712 client->router and client->connection pointers. Added check
1713 for these pointers being NULL to various places around the
1714 code. Affected file silcd/server.c.
1716 * Added client->data.registered == TRUE checks to various
1717 places around the code to assure that unregistered client's
1718 are not handled when it is not allowed. Affected file
1721 * Added `bool registered' fields to all
1722 silc_idlist_[server|client]_get_* routines to indicate whether
1723 the fetched client needs to be registered or not. Affected
1724 file silcd/idlist.[ch].
1726 * Add your own entry as registered to the ID cache in the
1727 server. Affected file server.c.
1729 * Fixed a bug in silc_server_new_server. The SilcServer was
1730 set as the new server's context instead of SilcServerEntry.
1731 This naturally caused some weird bugs.
1733 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Do not delete the channel rekey task when adding it
1736 for in silc_server_create_channel_key.
1738 * Changed the silc_server_create_channel_key to return
1739 TRUE or FALSE to indicate the success of the channel key
1742 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1744 * Fixed MSVC++ project files and added missing files to
1745 Makefiles under win32/.
1747 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1749 * Do not add TCP_NODELAY flag if the operating system
1750 does not have it defined. Affected files are
1751 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1753 * Fixed buffer overflow from Irssi SILC Client. Affected
1754 file irssi/src/fe-common/core/themes.c.
1756 * Fixed double free in client library in the file
1757 lib/silcclient/client.c when disconnecting from server.
1759 * Applied double free patch from cras to Irssi SILC client.
1760 Affected files irssi/src/core/[modules/expandos].c
1762 * Fixed the disconnection handling to Irssi SILC Client.
1763 The application must call silc_client_close_connection
1764 in ops->connect client operation in case of failure of
1765 the connection. Affected file is
1766 irssi/src/silc/core/client_ops.c.
1768 * Do not set sock->protocol to NULL in the function
1769 silc_client_close_connection after executing the protocol's
1770 final callback since the sock might not be valid anymore.
1771 Affected file lib/silcclient/client.c.
1773 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1775 * Do not enable SILC_THREADS if the linking with libpthread
1776 did not happen. Affected file configure.in.pre.
1778 * Added notion to protocol specification that server must
1779 verify the sent authentication payload with CMODE when
1780 setting the channel founder key. Implemented it to the
1781 server. Affected file silcd/command.c.
1783 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1785 * Added _EXTRA_DIST SILC distribution variable to the
1786 distributions file. It is used to conditionally add extra
1787 files or directories to the specific distribution. Affected
1788 files ./prepare, Makefile.am.pre and distributions.
1790 Removed the `_' from the start of the distribution names.
1793 * Added README.WIN32 for instructions to compile the Toolkit
1796 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Fixed a double free in disconnection in the server. Affected
1799 file is silcd/server.c.
1801 * Fixed the lib/silcske/groups.c to work now also with GMP
1802 MP library. The string conversion did not work when using
1803 specific base and the base is indicated in the string as well.
1805 * Created win32/ directory which now includes MSVC++ specific
1806 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1807 It will appear only in the toolkit distribution
1809 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1811 * Changed the key material distribution function in case when
1812 the hash output is too short. The data is now concatenated
1813 a bit differently than it used to. Made the change to the
1814 SKE protocol specification.
1816 * Added better GMP detection to configure.in.pre. A patch
1819 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1821 * Fixed a minor bug in SKE that might cause some problem on
1822 some platforms. Affected file lib/silcske/silcske.c.
1824 * Added the cookie checking for initiator in the SKE. It checks
1825 that the responder returns the sent cookie unmodified. The
1826 affected file is lib/silcske/silcske.c. Added new SKE
1827 error type INVALID_COOKIE that can be sent during the
1828 negotiation. Fixed some memory leaks as well.
1830 * Added the "invalid cookie" error message to Irssi SILC client's
1833 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1835 * Added `task_max' field to the SilcClientParams to indicate
1836 the maximum tasks the scheduler can handle. If set to zero,
1837 default values are used. Affected file lib/silcclient/silcapi.h.
1839 * Fixed memory leaks in silc_client_close_connection. Affected
1840 file lib/silcclient/client.c.
1842 * Added silc_client_del_client_entry to client library to free
1843 all memory of given client entry. Affected file is
1844 lib/silcclient/idlist.[ch].
1846 * Added new functions silc_client_del_channel and
1847 silc_client_del_server to delete channel and server entries.
1848 Affected file lib/silcclient/[silcapi.h/idlist.c].
1850 * Removed silc_client_del_client_by_id from silcapi.h.
1852 * Fixed the INFO command to return the server's own info
1853 correctly when querying by Server ID. Affected file is
1856 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * Removed the non-blocking settings in WIN32 code in the
1859 silc_sock_[read/write] and added SleepEx instead. Affected
1860 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1861 of input data is now checked with FIONREAD and ioctlsocket.
1863 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Call silc_schedule_task_del_by_context in the
1866 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1867 Affected file lib/silccore/silcprotocol.c.
1869 * Call silc_protocol_cancel for active protocols in the
1870 silc_server_close_connection if the funtion
1871 silc_server_free_sock_user_data has not been called.
1872 Affected file silcd/server.c.
1874 * Generic tasks cannot be deleted using the del_by_fd
1875 task deleting function since generic tasks does not match
1876 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1878 * Added a notion to SILCOPER help file that the SILCOPER works
1879 only on router server, not on normal server.
1881 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * Added for WIN32 support for the new scheduler as well.
1884 Affected file lib/silcutil/win32/silcwin32schedule.c.
1886 * Fixed the SHA1 implementation to work on various platforms.
1888 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1890 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1891 API. It is part of the scheduler now. Everything else is
1892 as previously but some functions has changed their names.
1893 Checkout the lib/silcutil/silcschedule.h for the interface.
1894 Updated all applications to use the new interface. Affected
1895 files are lib/silcutil/silcschedule.[ch].
1897 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Found a bug in the SKE implementation. The HASH value,
1900 specified by the protocol, was not computed correctly. The
1901 public key of the responder was not added to the computation
1902 even though it is mandatory. Affected file lib/silcske/silcske.c.
1903 This unfortunately causes incompatibilities with older
1904 clients and servers.
1906 * Added WIN32 specific network init and uninit functions:
1907 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1908 the Winsock2. Affected file lib/silcutil/silcnet.h and
1909 lib/silcutil/win32/silcwin32net.c.
1911 * Set the socket always to nonblocking mode on WIN32 after
1912 reading data or writing data. Affected file is
1913 lib/silcutil/win32/silcwin32sockconn.c.
1915 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * Fixed various compilation problems under WIN32. Affected
1918 files lib/silcutil/win32/silcwin32thread.c and
1919 lib/silcutil/win32/silcwin32schedule.c.
1921 * Removed all _internal.h #includes from public header
1922 files. Internal headers must never be included from
1925 Removed also the lib/silcske/payload_internal.h file.
1927 * All include files that may be needed (public and some others
1928 included by the public headers) by application developers are
1929 now copied to the ./includes directory. It does not copy any
1930 internal headers. Affected file Makefile.defines.pre and all
1931 Makefile.am's under lib/ and subdirs.
1933 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * Do not change the ~/.silc directory's permissions automatically.
1936 Affected file irssi/src/silc/core/clientutil.c.
1938 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Do not cancel the protocol in silc_server_close_connection
1941 it might cause recursion. Now cancelled in the function
1942 silc_server_free_sock_user_data. Affected file silcd/server.c.
1944 * Fixed the silc_server_remove_clients_by_server to regenerate
1945 the channel keys correctly finally. Added also new function
1946 silc_server_remove_clients_channels to actually do it.
1947 Affected file silcd/server.c.
1949 * Fixed the silc_server_new_channel to not crash by giving
1950 wrong router to the new channel. Affected file is
1951 silcd/packet_receive.c.
1953 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1955 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1956 which is given as argument to the silc_client_alloc now.
1957 It can be used to configure the client and set various parameters
1958 that affect the function of the client.
1960 * The USERS command in server did not check whether the channel
1961 is private or secret. Affected file silcd/command.c.
1963 * Added new argument to the USERS command in protocol specification.
1964 The USERS command now can take the channel name as argument
1965 as well. Added support for this in client and server and
1966 updated the protocol specs.
1968 * Completed the GETKEY command in client. It can be now used
1969 to fetch also servers public key not only some clients.
1970 Affected files lib/silcclient/command[_reply].c.
1972 * Added silc_client_get_server to return server entry by the
1973 server name. Affected files lib/silcclient/silcapi.h and
1976 * Redefined the IDENTIFY command in protocol specification to be
1977 more generic. It now can be used to query information about
1978 any entity in the SILC Network, including clients, servers and
1979 channels. The query may be based either the entity's name
1980 or the ID. Added support for this in both client and server.
1982 Affected files silcd/command.c and lib/silcclient/command.c
1983 and command_reply.c.
1985 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1986 the _from_client and _from_server functions. Affected file
1989 * Added silc_client_get_channel_by_id_resolve to the file
1990 lib/silcclient/silcapi.h to resolve channel information by
1991 its ID. Added also silc_client_get_channel_by_id that
1992 does not resolve it from the server.
1994 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1996 * Added SilcServerEntry context into the client library
1997 to represent one server. The INFO command now allocates
1998 these to save the resolved server info. For now on the
1999 client library will also keep information about servers,
2000 connected and resolved with INFO.
2002 The INFO command now allocates the SilcServerEntry context
2003 and saves the server info there. The COMMAND_REPLY in
2004 the INFO now returns the parameters to application in
2005 same order as defined in the protocol specification.
2007 The entries are cached in the client->server_cache.
2009 * The INFO command is now issued after received the Client ID
2010 from the server. Affected file lib/silcclient/client.c.
2012 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2013 to the application as the mode changer might be server.
2014 It is guaranteed that NULL is not returned anymore to the
2015 application. Affected file lib/silcclient/client_notify.c.
2017 The ID Type is now also passed to the application so that
2018 it can check whether the returned entry is SilcClientEntry
2021 Added new function silc_client_get_server_by_id to return
2022 the server entry by ID. Affected files are the
2023 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2025 * Do not create the channel in the Irssi SILC Client when issuing
2026 the JOIN command but when received the sucessful JOIN command
2027 reply. Otherwise the channel might get created even though we
2028 could not join it. The Affected file is
2029 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2031 * Fixed a channel joining bug in router. The router must also
2032 check the channel modes, invite and ban lists etc. when serving
2033 the JOIN command sent by normal server. Affected file is
2034 silcd/command.c. The router now resolves the client's
2035 information from the server who sent the JOIN command if it
2036 does not know it, and processes the JOIN command only after
2039 * Changed the SilcCommandCb to take new argument; void *context2.
2040 Affected file lib/silccore/silccommand.h
2042 The second argument in the command callbacks in the server now
2043 includes the SilcServerCommandReplyContext if the command was
2044 called as pending command callback from the command reply.
2045 Otherwise it is NULL. When called as pending the status of the
2046 command reply will be checked and if it was erronous the
2047 error will be sent to the original sender of the command.
2048 This way the client always receives the error messages even
2049 though the server was actually the one who received the error
2050 when it resent the command to router, for example. Affected
2051 files silcd/command[_reply].[ch].
2053 * Fixed sending WHOWAS command's error message to client if
2054 the requested client could not be found. It was missing.
2057 * Changed the CMODE and CUMODE commands reply arguments in the
2058 protocol specification. The Channel ID is now sent in both
2059 of the commands to identify the channel. Implemented this
2060 new feature to the client and server. Affected files
2061 lib/silcclient/command_reply.c and silcd/command.c.
2063 * Made better checks for invite and ban lists in the JOIN
2064 command in server. Affected file silcd/command.c.
2066 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2068 * The server now performs the incoming host IP/DNS lookup
2069 using the silc_socket_host_lookup and thus does not block
2070 the server anymore. Affected file silcd/server.c.
2072 * Completed the multi-thread support for SILC Scheduler in
2073 the lib/silcutil/silcschedule.c.
2075 * Fixed the configure.in.pre to detect the pthread correctly
2078 * Fixed a deadlock in silc_task_queue_wakeup in the file
2079 lib/silcutil/silctask.c.
2081 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Added new function silc_schedule_wakeup that is used in
2084 multi-threaded environment to wakeup the main thread's
2085 schduler. It needs to be used when a thread adds a new task
2086 or removes a task from task queues. After waking up, the
2087 scheduler will detect the task queue changes. If threads
2088 support is not compiled in this function has no effect.
2089 Implemented the wakeup mechanism to both Unix and WIN32
2090 systems. Affected files are lib/silcutil/silcschedule.[ch],
2091 lib/silcutil/unix/silcunixschedule.c and the
2092 lib/silcutil/win32/silcwin32schedule.c.
2094 * Added new function silc_task_queue_wakeup to wakeup the
2095 scheduler by the specified task queue. Affected file
2096 lib/silcutil/silctask.[ch].
2098 * The silc_socket_host_lookup_start now wakes up the scheduler
2099 after adding the timeout task. Affected file is
2100 lib/silcutil/silcsockconn.c.
2102 * The silc_socket_host_lookup is synchronous now if the threads
2103 support is not compiled in. However, the callback is still
2104 called asyncronously through the scheduler, anyway. Affected
2105 file lib/silcutil/silcsockconn.c.
2107 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Added new function silc_socket_host_lookup to perform
2110 asynchronous IP and FQDN lookups for the socket connection.
2111 Affected files lib/silcutil/silcsockconn.[ch].
2113 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2115 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2116 that may or may not compile the mutex support in.
2118 Changed the silc_mutex_alloc interface. It allocates the
2119 mutex now to the sent pointer and returns TRUE or FALSE.
2121 Affected file lib/silcutil/silcmutex.h.
2123 * Wrote the SILC Task Queue interface to support multi-threads.
2124 Affected file lib/silcutil/silctask.[ch].
2126 * Wrote the SILC Scheduler to support multi-threads. Affected
2127 file lib/silcutil/silcschedule.c.
2129 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2131 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2132 in lib/silcutil/win32/.
2134 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2136 * Defined SILC Mutex API and SILC Thread API and implemented
2137 them for Unix. Affected files are
2138 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2139 lib/silcutil/unix/silcunixmutex.c and
2140 lib/silcutil/unix/silcunixthread.c.
2142 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2144 * Fixed the silc_server_remove_clients_by_server's channel
2145 key re-generation. The hash table handling was incorrect
2146 and would not work with many channels. Affected file is
2149 * Fixed some memory leaks around the server code.
2151 * Rewrote the silc_server_get_users_on_channel to support IPv6
2152 based Client ID's. Affected file silcd/server.c.
2154 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2155 specification. However, a separate document must be written
2156 to define the detailed signing procedure and the payload
2157 associated with the flag. Defined the flag to the
2158 lib/silccore/silcchannel.h as well.
2160 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2162 * Changed the dynamic tables to static size tables in the
2163 lib/silccrypt/silchmac.c.
2165 * Removed GCC dependencies from the code. A patch by cras.
2167 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2169 * Do not show the error "Error receiving packet bla bla"
2170 in server if it really was not an error (-2 means that reading
2171 is pending). Affected file silcd/server.c.
2173 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * Fixed a possible crash in silc_server_remove_clients_by_server
2176 in silcd/server.c. Fixed there also some memory leaks.
2178 * Fixed the silc_idlist_replace_client_id. It could replace
2179 wrong key in the hash table. Affected file silcd/idlist.c.
2181 * Do not check whether there are global users on the channel
2182 if the channel->global_users is FALSE. Affected functions
2183 silc_server_remove_from_one_channel and
2184 silc_server_remove_from_channels in silcd/server.c. Also,
2185 do not check if the removed client is local as we can be
2186 sure that global client was not removed from the channel
2187 and checking for global users is not needed.
2189 * The silc_server_remove_clients_by_server now re-generates
2190 the channel keys correctly for those channels that had
2191 clients removed from them. Affected file silcd/server.c.
2193 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Found the reason of random crashes in the server. We weren't
2196 ignoring the SIGPIPE signal (which can be sent in write())
2197 and it crashed the server. Affected file silcd/silcd.c.
2199 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2201 * Assure that sock->user_data is not NULL in the function
2202 silc_server_packet_send in silcd/packet_send.c.
2204 * Disconnect the remote connection if it could not be added
2205 to any ID lists in the server. The affected file is
2208 * Check in silc_server_packet_send[_real/dest] that the
2209 socket is not disconnecting and ignore the data if it is.
2210 Affected file silcd/packet_send.c.
2212 * Define inline to __inline on native WIN32 compilation.
2213 Affected file includes/silcwin32.h.
2215 * Added some explicit type casts for inline code since MSVC
2216 require them. Affected files lib/silcutil/silcbuffer.h,
2217 lib/trq/silcdlist.h and lib/trq/silclist.h.
2219 * Print warning in log files from now on if the packet
2220 decryption fails. Affected file silcd/server.c.
2222 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * Changed the `say' client operation's interface to accept
2225 new `type' argument to indicate the type of the message sent
2226 by the library. The application may filter the library's
2227 messages according the type. The affected file is the
2228 lib/silcclient/silcapi.h.
2230 * Added two new functions to lib/silcclient/silcapi.h:
2231 silc_client_del_client and silc_client_del_client_by_id.
2232 Affected file lib/silcclient/idlist.c.
2234 * Moved the clientincludes.h from includes/ to silc/ and
2235 serverincludes.h from includes/ to silcd/.
2237 * The modes for the CMODE and CUMODE are now passed as
2238 uint32 for application with COMMAND_REPLY. The affected
2239 file is lib/silcclient/command_reply.c.
2241 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2243 * /WHOIS without arguments shows client's own information.
2244 Affected file lib/silcclient/command.c.
2246 * Changed PING to not accept any arguments. The specs
2247 says that client can ping only the connected server so
2248 requiring an argument is not needed. Affected file is
2249 lib/silcclient/command.c.
2251 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Fixed a fatal bug in private message sending and reception
2254 encryption and decryption when using private message keys.
2255 The implementation was incorrect and did not follow the
2256 specification. It causd that some of the message were
2257 lost since it did not use the sending and receiving keys
2258 as the protocol suggests. This has been fixed and will cause
2259 incompatibilities with older clients when sending private
2260 message encrypted with private message keys. Affected files
2261 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2262 and various other in Irssi SILC Client.
2264 Added `responder' boolean argument to the functions
2265 silc_client_add_private_message_key[_ske] to indicate when
2266 the key is added as responder or initiator of the key
2269 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * Removed the silc_ske_check_version function and created
2272 a SilcSKECheckVersion callback. Added also a function
2273 silc_ske_set_callbacks that is now used to set all SKE
2274 callbacks. The callback functions are not given to
2275 the SKE functions anymore, but this function is used to
2278 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2280 * Added `silc_version' argument to the silc_client_alloc
2281 to define the version of the application for the library.
2282 The library will use the version string to compare it
2283 against the remote host's (usually a server) version
2284 string. Affected file lib/silcclient/silcapi.h
2286 * Added the KE protocol context to Key Agreement context
2287 in client library so that we can abort the SKE if it
2288 is in process when we get timeout. Affected file is
2289 lib/silcclient/client_keyagr.c.
2291 * Do not resolve the client ID forever if it returns in the
2292 first time that such client does not exist. This was done
2293 for example with private message. Affected file is
2294 lib/silcclient/client_prvmsg.c.
2296 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2298 * Do not add regex.h for WIN32. The affected file
2299 includes/silcincludes.h.
2301 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2302 not work yet 100%. It generates the DLL's automatically
2303 when compiling with --with-win32 under cygwin.
2305 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * lib/contrib/regex.c is not compiled on WIN32.
2309 * Added silc_net_get_socket_opt function to the
2310 lib/silcutil/silcnet.h.
2312 * Added includes/silcwin32.h for WIN32 specific includes
2315 * Do not use ptime structure or any of the posix process
2316 functions on WIN32 in lib/silccrypt/silrng.c.
2318 * Added silc_gettimeofday to provide generic function
2319 for struct timeval on all platforms. Added the function
2320 to lib/silcutil/silcutil.h.
2322 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2324 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2325 library as they clearly belong there. As a plus side we
2326 can make the actual socket connection routines platform
2329 Added also new generic function silc_socket_read and
2330 silc_socket_write (that used to be silc_packet_[read/write].
2331 The implementation of these are platform specific.
2333 * Added WIN32 specific routines of silc_socket_[read/write]
2334 to lib/silcutil/win32/silcwin32sockconn.c.
2336 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Added preliminary support for native WIN32 compilation under
2339 cygwin (using the -mno-cygwin option for GCC) to the
2340 ./configure.in.pre. The --with-win32 now prepares the
2341 compilation for native WIN32.
2343 * Rewrote the SILC Scheduler interface in the file
2344 lib/silcutil/silcschedule.h. The scheduler is now context
2345 based and does not have anymore any global static scheduler.
2346 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2347 and created lib/silcutil/win32 directory for WIN32 based
2350 * Added Unix specific network routines to the
2351 lib/silcutil/unix/silcunixnet.c and the old
2352 lib/silcutil/silcnet.c includes now only generic routines.
2354 Added WIN32 specific network routines to the
2355 lib/silcutil/win32/silcwin32net.c.
2357 * Added Unix specific utility functions from the
2358 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2360 * Added WIN32 SILC Scheduler to the file
2361 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2364 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Do not handle JOIN notify in the server if the target client
2367 is not registered (idata->registered == FALSE). The affected
2368 file is silcd/packet_receive.c.
2370 * Update the nickrec->founder in event_cumode in the Irssi SILC
2371 client. Affected file irssi/src/silc/core/silc-channels.c.
2373 * Fixed the CUMODE_CHANGE notify handling in the server when
2374 server and router are announcing their clients on channels.
2375 Now the mode changes are saved and notified correctly. The
2376 affected file is /silcd/packet_receive.c.
2378 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2379 They really did not replace the cache entry in the ID Cache.
2380 Now they do that. Affected file silcd/idlist.c.
2382 * Fixed the KICK notify handling in the Irssi SILC client to
2383 update the channel records so that the kicked client does not
2384 appear to be on the channel. The affected file is
2385 irssi/src/silc/core/silc-channels.c.
2387 * Always update the conn->current_channel when executing command
2388 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2390 * Fixed the KILL notify handling in Irssi SILC client to remove
2391 the killed client on all channels.
2393 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Fixed the silc_parse_command_line to remove extra spaces
2396 from the start and end of the arguments. Affected file is
2397 lib/silcutil/silcutil.c.
2399 * Cancel and free any active protocol in the function
2400 silc_server_close_connection. Affected file silcd/server.c.
2402 * Cancel and free any active protocol in the function
2403 silc_client_close_connction. Affected file is
2404 lib/silcclient/client.c.
2406 * Do not execute the KILL command for clients that are in
2407 history (ie. they are not in the network). Affected file is
2410 * Fixed KILL notify handling, client does not crash anymore.
2411 Affected file irssi/src/silc/core/silc-channels.c.
2413 * Reduced the default packet buffer size from 2048 to 1024 in
2414 lib/silccore/silcpacket.c.
2416 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2417 counter to the SKE context that is incresed when the SKE library
2418 performs async operation outside the library. If the outside
2419 process frees the SKE context and FREED status will be set
2420 and the library will detect after the sync operation that the
2421 libary is freed. The affected files are
2422 lib/silcske/silcske[_status].[ch].
2424 * Resolve the client entry information in the function
2425 silc_client_channel_message to assure that NULL pointer is not
2426 passed as client entry to the application. */
2428 * Fixed the task timeout calculation to assure that there is
2429 never negative timeouts. The affected file is
2430 lib/silcutil/silcschedule.c.
2432 * Fixed the channel user mode notification sending in server.
2433 It was sent point-to-point to the router (or to server by router)
2434 but it needs to be destined to a channel. The routines now
2435 supports sending the channel user mode notifys to the channels
2436 when announcing clients and channels. Affected files are
2437 silcd/server.c and silcd/packet_receive.c.
2439 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2440 It did not actually replace the old channel entry in the cache.
2441 Affected file lib/silcclient/client_notify.c.
2443 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2445 * Fixed a possible crash in silc_packet_send_prepare. It now
2446 assures always that there is enough space in the buffer and
2447 at the tail area of the buffer (for MAC).
2449 Fixed the inbound buffer reallocation in silc_packet_read.
2450 It was old code and did not handle the reallocation correctly.
2453 The affected file is lib/silccore/silcpacket.c.
2455 * Fixed buffer overflow in silc_parse_nickname in the file
2456 lib/silcutil/silcutil.c.
2458 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * make install generates new server keys only if there is not
2463 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2466 Added check that if the NOREPLY is set then we will not send
2467 the away message. This avoids infinite loop of away messages
2468 if both clients are away. The affected file is
2469 lib/silcclient/client_prvmsg.c.
2471 * Fixed client crash if /NICK was given without arguments.
2472 Affected file lib/silcclient/command.c.
2474 * Server does not send the invite list in INVITE command back
2475 to the client if the list was not altered. Added this notion
2476 to the protocol spec as well. Affected file silcd/command.c.
2478 Fixed possible crash in INVITE command by checking the
2479 value of silc_server_get_client_route command.
2481 * Fixed the INVITE notify type handling. The arguments are now
2482 taken in correct order and client does not crash. The affected
2483 file is irssi/src/silc/core/silc-channels.c.
2485 Removed the "Inviting xxx to channel" message from the
2486 client library away and let the application handle it.
2487 Affected file lib/silcclient/command.c. Added that message
2488 to Irssi SILC client's message formats.
2490 * Fixed CMODE command crash in client. It now checks the
2491 amount of arguments correctly and does not crash. The affected
2492 file is lib/silcclient/command.c.
2494 * Do not create new channel automatically in silc_channels_join
2495 but check whether the channel by that name already exists.
2496 Affected file irssi/silc/core/silc-channels.c.
2498 * Do not send the SERVER_SIGNOFF to router if the disconnected
2499 entity was the router. Affected file silcd/server.c.
2501 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2502 SILC client as it was missing from there.
2504 Added the handling of the KICK notify to the Irssi SILC client
2505 as it was missing. Added "you have been kicked" message to
2506 Irssi SILC client's message modules formats.
2508 Added the handing of the KILL notify to the Irssi SILC client
2509 as it was missing. Added the kill message module formats
2512 The affected file is irssi/src/silc/core/silc-channels.c.
2514 * The router did not save the channel mode the server announced.
2515 Affected file silcd/packet_receive.c.
2517 * Fixed a possible crash in INFO command in server. If the
2518 server did not provide the server info it crashed. Affected
2519 file silcd/command.c.
2521 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2523 * Fixed the GETKEY command in the server to check also the
2524 global list. Otherwise the GETKEY would not work correctly
2525 in normal SILC server. Affected file silcd/command.c.
2527 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2529 * Fixed GETKEY crash, it crashed if the command did not succseed.
2531 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2533 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2534 is now real and not just an macro interface to GMP.
2536 Removed the entire GMP from the source tree and imported new
2537 NSS MPI library instead. Reason for removing GMP is that it is
2538 extremely large and compiles extremely slow. The NSS MPI
2539 is only a few files and compiles in less than 10 seconds.
2540 The speed is also about the same as GMP. The MPI is imported
2541 to lib/silcmath/mpi.
2543 If the system has GMP installed we will still use the GMP.
2544 If it is not then the NSS MPI will be compiled.
2546 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2548 * Merged a long nickname (127 characters long) crash bugfix from
2549 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2551 * Merged a freed memory reference bugfix from Irssi CVS tree.
2552 Affected file irssi/src/core/commands.c.
2554 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * Added the server's public key sving and verification to the
2557 server when performing the SKE. This was missing and the
2558 remote server's (or router's) public key was accepted without
2559 checking whether we have it previously or trust it at all.
2560 Affected file silcd/protocol.c.
2562 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * Check in the silc_server_timeout_remote if protocol is active
2565 and make sure that the protocol's final callback is called so
2566 that all memory if freed. Affected file silcd/server.c.
2568 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * silc_server_whois_send_reply crashed the server if the nickname
2571 was 127 characters long. Affected file silcd/command.c.
2573 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2575 * Added sanity check to the silc_server_new_client. If the hostname
2576 is provided inside username then check that the provided hostname
2577 really is the same as the resolved one. If the hostname was not
2578 resolved then check it from the public key. Affected file is
2579 silcd/packet_receive.c.
2581 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2582 if the server disconnected us and the connection is not valid
2583 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2585 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2586 the library to the lib/silcutil/silcutil.[ch].
2588 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2590 * Close log file after open. Affected file
2591 lib/silcutil/silclog.c.
2593 * Check whether sock == NULL in silc_client_send_packet and return
2594 if it is. Affected file lib/silcclient/silcclient.c.
2596 * Check rec->entry == NULL in the Irssi SILC Client before
2597 sending the channel message. Affecte file is
2598 irssi/src/silc/core/silc-servers.c.
2600 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * Merged a splitted window bugfix from Irssi CVS tree. The
2603 affected file is irssi/src/fe-text/textbuffer-view.c.
2605 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2606 It did not print nickname.
2608 * Improved the distributions system a bit.
2610 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2613 irssi/src/fe-text/gui-window.c.
2615 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2616 to in-active server. The affected file is
2617 irssi/src/silc/core/client_ops.c.
2619 * Resolve the client in USERS command reply if the entry does
2620 not have username resolved. The affected file is
2621 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2622 command to WHOIS command to really resolve stuff. The USERS
2623 is not used any more in any critical section so WHOIS can
2624 be used even though it might be slower than IDENTIFY.
2626 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2629 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Changed the protocol API a bit more consistent in the
2632 lib/silccore/silcprotocol.[ch].
2634 * Changed the following headers to ROBODoc format:
2636 lib/silccore/silcpayload.h
2637 lib/silccore/silcprotocol.h
2638 lib/silccore/silcsockconn.h
2640 All core library headers are now formatted.
2642 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Fixed a bug in Irssi SILC client; do not show that you are
2645 server/router operator if you really are not. Affected file is
2646 irssi/src/silc/core/client_ops.c.
2648 * Renamed silc_command_free_payload to silc_command_payload_free.
2649 Affected file lib/silccore/silccommand.h
2651 * Added silcmath.h to include the prototoypes of various routines
2652 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2655 * Changed the following headers to ROBODoc format:
2657 lib/silccore/silcchannel.h
2658 lib/silccore/silccommand.h
2659 lib/silccore/silcid.h
2660 lib/silccore/silcidcache.h
2661 lib/silccore/silcmode.h
2662 lib/silccore/silcnotify.h
2663 lib/silccore/silcpacket.h
2664 lib/silcmath/silcmath.h
2666 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * Added checking to the server code not to start the server if
2669 ciphers and stuff are not configured properly. Affected files
2670 silcd/serverconfig.[h] and silcd/server.c.
2672 * Changed the layout of the header files of the public interfaces
2673 in the SILC libraries. The new layout supports ROBODoc
2674 documentation tool (and some others) so that it is easy to create
2675 a library reference manual. All the other headers and source
2676 code must still follow the CodingStyle document. Also source
2677 code must not include these ROBODoc stuffs, only the headers.
2678 Furthermore, all public interface headers must now be named
2679 by using `silc' prefix, example: silcapi.h, silccipher.h.
2680 Some files were renamed due to this. All the other headers
2681 must not be used as public interfaces. I will update the
2682 CodingStyle document later. Changed following headers, so far:
2684 lib/silcclient/silcapi.h
2685 lib/silccore/silcauth.h
2686 lib/silccore/silcprivate.h
2687 lib/silccrypt/silcdh.h
2689 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2693 * Removed silc_client_packet_send_flush from the client library
2694 as it is not needed. Affected file lib/silcclient/client.[ch].
2696 * Added printing of message of unresolved authentication method
2697 to the Irssi SILC client. Added it to the module formats.
2698 Removed the same message from the client library.
2700 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Added new distribution feature, DISTLABEL. Every distribution
2703 can define own preprocessor label that can be used in the
2704 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2705 file distributions, acconfig.h.pre and prepare.
2707 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2709 * Added Makefile.defines_int to include the actual definitions
2710 for Makefile.defines.in. Tested the new distribution system,
2711 created distributions and tested installation.
2713 * Added AWAY message printing to the Irssi SILC client. Added
2714 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2716 * Added SCONNECT command to call the SILC's CONNECT command.
2717 Cannot use CONNECT directly since Irssi uses that internally.
2718 Affected file irssi/src/silc/core/silc-servers.c.
2720 Added ACTION local command. It is same as ME command but takes
2721 the channel as mandatory argument.
2723 Rewrote some of the Irssi's help files to suite for SILC
2726 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Added Makefile.defines[.in] that should for now on be included
2729 in all Makefile.am file in the source tree. That file includes
2730 all common compilation definitions for SILC source tree.
2732 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2734 * Minor changes to the ./prepare script to change the package
2735 name according the distribution name to the configure.in.
2737 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Created new distribution system. Added file `distributions'
2740 that defines all the distributions that can be created out of
2741 the SILC source tree. The ./prepare script now reads that
2742 file to determine how to prepare the distributions. The
2743 first argument to the ./prepare is the name of the distribution
2744 and second is the version of the distribution. If given
2745 without arguments it creates the default (toolkit) distribution
2746 with the default version (defined in ./prepare).
2748 All Makefile.am files that are subject to the distributions
2749 are now named as Makefile.am.pre. These are ./Makefile.am
2750 and lib/Makefile.am. Others may be changed later.
2752 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2754 * Added invite list, ban list, some key management and connection
2755 error message printing to module formats in the Irssi SILC client.
2757 * Added new silc_client_set_away_message to set the away message
2758 that is back to the person who sent private message. The
2759 affected file lib/silcclient/silcapi.h and the
2760 lib/silcclient/client_prvmsg.c.
2762 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2764 * Fixed the private message sending in the Irssi SILC client,
2765 added local command KEY to the Irssi SILC client.
2767 Added key management and key agreement message formats to the
2768 irssi/src/fe-common/silc/module-formats.[ch].
2770 Added USERS (alias WHO) printing, server/router operator
2771 indication and LIST command printing to the module formats.
2773 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2775 * Fixed channel joining notify handling, cumode notify handling
2776 from Irssi SILC client.
2778 * Added SILC specific module-formats to the Irssi SILC client so
2779 that SILC specific message hilighting, colors etc is possible.
2780 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2782 Added channel mode, channel user mode, actions, notices,
2783 whois and whowas printing to the the module-formats.c.
2785 * Fixed a bug in channel deletion in the server. The channel
2786 is not left to the cache even if the channel founder auth mode
2787 is set when there are no users anymore on the channel. Affected
2788 file silcd/server.c.
2790 * The silc_net_localhost now resolves the entire hostname including
2791 the domain name. Affected file lib/silcutil/silcnet.c.
2793 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2795 * Changed the ask_passphrase client operation to be ascynchronous.
2796 It has now a completion callback and a context that the
2797 application must call after it has got the passphrase from
2798 the user. Affected files lib/silcclient/silcapi.h,
2799 lib/silcclient/protocol.c, lib/silcclient/command.c and
2802 Added SilcAskPassphrase callback that the application calls
2803 to deliver the passphrase to the library.
2805 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2806 The public key verification and especially a certificate
2807 verification is asynchronous procedure.
2809 Added new SILC_SKE_STATUS_PENDING status to indicate the
2810 request is pending and a callback will be called to finalize
2813 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2814 indicate that remote end did not send its public key (or
2815 certificate), even though we require it. Added check for this
2816 condition in the SKE. This was a security bug, now fixed.
2818 Defined new SilcSKEVerifyCbCompletion callback that is called
2819 when the verification process is completed.
2821 The affected files lib/silcske/silcske_status.h and
2822 lib/silcske/silcske.[ch].
2824 * Changed the verify_public_key client operation to be async
2825 as well. Defined SilcVerifyPublicKey callback that is used to
2826 indicate the success of the public key verification process.
2828 Changed the server and client to use the new async client
2831 * Changed the Irssi SILC client's internal scheduler to be called
2832 twice as many times as it used to be. As a result the client
2833 should be a bit faster now. Affected file is
2834 irssi/src/silc/core/silc-core.c.
2836 * Added support to Irssi SILC client of asynchronous public key
2837 verification and passphrase inquiry. Affected file is
2838 irssi/src/silc/core/silc-core.c.
2840 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2842 * Do not say "You have left channel %s" in client library.
2843 Moved it to the application. Affected files are
2844 lib/silcclient/command.c and silc/client_ops.c.
2846 * Fixed silc_client_get_clients. Command context was not
2847 duplicated and was freed memory in the callback. Affected
2848 file lib/silcclient/idlist.c.
2850 * Do not say "you are now talking..." on JOIN command in the
2851 client library. The appliation must handle it.
2853 * Do not say ".. changed topic to" in command reply in the
2854 client libary. The application must handle it.
2856 * Fixed TOPIC command sending in the client library.
2858 * Fixed a memory leak in silc_client_command_free in the file
2859 lib/silcclient/command.c.
2861 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2863 * Imported a modified version of Irssi client to the source tree.
2864 The Irssi will be used to create a new client called
2865 Irssi SILC. Imported to irssi/.
2867 Added silc_core_init_finish function to the Irssi. Affected
2868 file irssi/configure.in.
2870 A lot changes in the Makefile.ams around the irssi tree.
2872 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Do not rehash if the new size is same as the old size of the
2875 hash table, in the silc_hash_table_rehash*. The affected file
2876 lib/silcutil/silchashtable.c.
2878 * Replaced hash_table_del_by_context calls from the server
2879 (when channel->user_list and client->channels) to the
2880 hash_table_del as it is sufficient and faster.
2882 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Added silc_hash_table_list, silc_hash_table_get and the
2885 SilcHashTableList structure to provide an alternative way to
2886 traverse the hash table. The affected files are
2887 lib/silcutil/silchashtable.[ch].
2889 * Changed the server's idlist routines to use the hash table
2890 routines to optimize the code.
2892 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Replaced the client entry's `channel' list and channel entry's
2895 `user_list' list to hash tables for optimized lookup. Changed
2896 the code to use the hash table interface around the code.
2897 Affected file lib/silcd/idlist.[ch].
2899 * Added `auto_rehash' boolean argument to the function
2900 silc_hash_table_alloc to indicate whether the hash table should
2901 auto-rehash when it thinks is appropriate time. It will
2902 increase the hash table size if the there is twice as much
2903 entries in the table than the size of the table, and will
2904 decrease the size if there are twice as less entries than
2905 the size of the table.
2907 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2911 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2913 * silc_idcache_purge_by_context deletes the entry now by context
2914 as it is supposed to do. Affected file lib/silccore/idcache.c.
2916 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2917 client is not anymore valid (WHOWAS givens the info) and not
2918 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2920 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2922 * Removed the `data' and `data_len' arguments from the ID Cache
2923 interfaces and added `name' argument. ID Cache does not handle
2924 anymore the binary data only a names associated with given ID.
2926 * When hashing a Client ID with silc_hash_id the entire ID is
2927 not hashed anymore, instead only the hash of the Client ID is
2928 hashed. This way we can access the Client ID from the cache
2929 with Client ID but with the hash of the ID (which is a hash of
2930 the nickname) as well without any difference in performance.
2932 Added also silc_idcache_find_by_id_one_ext to do one on one
2933 searching when we have the actual ID. Added also function
2934 silc_hash_client_id_compare. The affected files are
2935 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2937 * When hashing the name associated with a ID it is always done
2938 in lowercase. This way we can access the cache without worrying
2939 about case-sensitivity, even though, for example nicknames are
2942 * Fixed a bug in server with channel message sending. It put
2943 wrong ID type as destination ID. The affected file
2944 silcd/packet_send.c.
2946 * silc_idcache_del_by_context now deletes from all hash tables
2947 by context. Affected file lib/silccore/idcache.c.
2949 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Changed the client library to use the new ID Cache interface.
2952 Changes around the source tree.
2954 * Added silc_hash_table_rehash_ext to rehash with specific
2955 hash function. Affected file lib/silcutil/silchashtable.[ch].
2957 * Added silc_hash_string_compare to compare two strings in the
2958 hash table. Affected file lib/silcutil/silcutil.[ch].
2960 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2962 * Added new function silc_idcache_del_by_context into the
2963 lib/silccore/idcache.[ch].
2965 * Changed the server's ID list routines to use the new ID Cache
2966 interface. Changes around the source tree.
2968 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Added silc_hash_table_del[_by_context]_ext functions in to the
2971 lib/silcutil/silchashtable.[ch].
2973 Removed silc_hash_table_find_all* routines and added new
2974 silc_hash_table_find_foreach to replace them.
2976 Added silc_hash_table_replace_ext function as extended
2977 replacing function. Separated the simple hash table interface
2978 from the extended hash table interface in the file
2979 lib/silcutil/silchashtable.h.
2981 * Fixed minor bugs and changed it to use some of the new
2982 hash table functions in lib/silccore/idcache.c
2984 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2986 * Added new function silc_hash_table_find_all to return all keys
2987 in the hash table by the specified key. As the hash table is
2988 collision resistant it also makes it possible to have several
2989 duplicate keys in the hash table. This function may be used to
2990 find all of the keys from the hash.
2992 Added user_context arguments to the SilcHashFunction,
2993 SilcHashCompare and SilcHashDestructor to deliver user specified
2996 Added new fuctions silc_hash_table_find[_all]_ext to do
2997 extended lookup with specified hash and compare functions and
2998 specified user contexts.
3000 Added new function silc_hash_table_add_ext to add the key
3001 with specified hash function and user context.
3003 Added new function silc_hash_table_foreach to traverse all
3004 entrys in the hash table. Added SilcHashForeach callback
3007 Added new function silc_hash_table_del_by_context to delete
3008 the entry only if the context associated with the key matches.
3010 Affected files are lib/silcutil/silchashtable.[ch].
3012 * Removed silc_hash_[server/client/channel]_id and added just
3013 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3014 silc_hash_id_compare to compare two ID's using as the hash table
3015 comparison function. Added also silc_hash_data to hash
3016 binary data and silc_hash_data_compare to compare it.
3018 * Removed silc_idlist_find_client_by_hash as it is not needed
3019 anymore. Affected file silcd/idlist.[ch].
3021 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3022 to use internally the SilcHashTable. The new ID Cache is a lot
3023 faster than the old one. Some of the ID Cache interface was also
3024 rewritten and obsolete and stupid functions were removed.
3026 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3028 * Added entry_count field to the SilcHashTable to keep the number
3029 of the entries in the table. Implemented the function
3030 silc_hash_table_rehash. Added new function
3031 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3033 Fixed a minor bug in silc_hash_table_free.
3035 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3036 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3037 into the lib/silcutil/silcutil.[ch].
3039 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Implemented a collision resistant hash table into the
3042 lib/silcutil/silchashtable[ch]. See the header and the source
3043 for the SilcHashTable API.
3045 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3047 * Merged dotconf version 1.0.2 into lib/dotconf.
3049 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * Do not compile anything in lib/silcsim/* if the SIM support
3052 is not enabled. The tree should now compile without problems
3055 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Compiled the SILC under cygwin. Compiled and tested briefly
3058 without problems. More tests needed. The SIMs didn't compile
3061 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3063 * Fixed possible crash in silc_get_username in the
3064 lib/silcutil/silcutil.c.
3066 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3068 * Fixed a va_arg in silc/client_ops.c.
3070 * Oops, RC5 routines were named AES and caused some problems
3071 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3073 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Added new SilcIDIP structure into the lib/silccore/id.h and
3076 replaced the old `ip' fields from all SILC ID's to that type.
3077 This is a step towards IPv6 support.
3079 The silc_id_get_len takes now the ID as an extra argument.
3080 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3081 both IPv4 and IPv6 based ID's.
3083 The affected files are lib/silccore/id.[ch] and other files
3084 around the tree using these routines.
3086 * Removed the ID length arguments in server from various
3087 silc_server_send_notify_* routines -> they are not needed
3090 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Fixed memory leak in silc_encode_pem_file in the file
3093 lib/silcutil/silcutil.c.
3095 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Check minor version as well in the SKE. Affected files are
3098 silcd/protocol.c and lib/silcclient/protocol.c.
3100 * Added --identifier option to the server so that an identifier
3101 can be when creating the public key for the server. Affected
3102 file is silcd/silcd.c.
3104 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3105 lib/silccrypt/silcpkcs.c.
3107 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3109 * Register default ciphers and stuff when using -C option with
3110 the server. Affected file sildc/silcd.c.
3112 * Put back the servers public key filename format, it is better
3113 than the new one. For now, the client keys are saved with the
3114 new filename format. The affected file silc/client_ops.c.
3116 * Implemented the Cipher API for the rest of the ciphers that
3117 did not implement it or implemented it the wrong way.
3119 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Register default ciphers and stuff when using the -S option
3122 in the client. Affected file silc/silc.c. Same also when
3123 creating new key pair with -C option.
3125 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Fixed the silc_verify_public_key client operation function to
3128 save the public keys differently. The fingerprint is now
3129 used as filename and not the hostname. This way also the
3130 client keys are saved uniquely and not with hostnames. The
3131 affected file is silc/client_ops.c.
3133 * Trimmed the silc_hash_fingerprint function to remove extra
3134 whitespaces from the end of the fingerprint. The affected
3135 file is lib/silccrypt/silchash.c.
3139 * Added silc_cipher_register_default function to register all
3140 default ciphers. It can be used when configuration files
3141 does not exist and the application does not want any specific
3142 ciphers in any specific order.
3144 The SilcDList is now used as silc_cipher_list dynamically
3145 allocated cipher list. Removed the static list all together
3146 and now all ciphers must be allocated to the dynamic list.
3147 The silc_cipher_alloc routine was changed to check only the
3150 All silc_cipher_* routines that used to return int returns
3153 The affected files lib/silccrypt/silccrypt.[ch].
3155 * The same thing was done to silc_hash_* as for silc_cipher_*
3156 routines. Affected files lib/silccrypt/silchash.[ch].
3158 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3159 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3160 Added also silc_pkcs_[un]register[_default] functions.
3161 Removed the data_context from the PKCS API.
3163 * Added silc_hmac_register_default function to register default
3164 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3165 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3166 to unregister all hmacs at once.
3168 * Register the default ciphers, hash functions, PKCSs and HMACs
3169 if client's configuration file does not exist. The affected
3172 * The client did not load the hash functions from the SIM
3173 modules at all. Added support for this. Affected file is
3174 silc/clientconfig.c.
3176 * When decoding public key with silc_pkcs_public_key_decode, check
3177 the supported algorithm only if PKCS are registered. Affected
3178 file lib/silccrypt/silcpkcs.c. The same was done with the
3179 silc_pkcs_private_key_decode.
3181 * Fixed the SILC List routines to keep the list always in order.
3182 It used to change the list's order when traversing the list but
3183 not it preserves the order. Affected file lib/trq/silclist.h.
3185 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Added the client library to use the SilcSocketConnection's
3188 reference counter (by silc_socket_dup) to prevent the bug that
3189 the socket object may be freed underneath async operation.
3191 * The name resolv library checking fixes in the configure.in.pre.
3194 * Created new version of the protocol drafts for future
3195 development. The -03 drafts are the ones that will be changed
3196 in the trunk now and the -02 will remain as they are.
3198 * Send list of CUMODE notifys to the router when announcing
3199 the channel users to the router. Affected file silcd/server.c.
3200 If the router receiving channel founder CUMODE for a channel
3201 that already has channel founder it will send CUMODE notify
3202 to the sender to remove the channel founder rights from the
3203 announced client. Affected file silcd/packet_receive.c.
3205 * The CUMODE notify may now use Server ID as well as the entity
3206 who changes the mode. Updated protocool specs.
3208 * Updated INSTALL and README files.
3210 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3212 * New web pages in the http://silc.pspt.fi. The pages was
3217 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Implemented the [DenyConnectin] config section in the server.
3220 Added silc_server_config_denied_conn to check whether incoming
3221 connection is denied. Affected file silcd/serverconfig.[ch].
3223 * Do not check the ports when checking the incoming configuration
3224 data if the port is 0, meaning any. Affected file is
3225 silcd/serverconfig.c.
3227 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Fixed buffer overflow in silc_string_compare in the file
3230 lib/silcutil/silcutil.c.
3232 * Fixed double free in silc_server_command_leave in the file
3235 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Fixed the version checking in the server. Affected file is
3240 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Fixed the configuration data fetching when accepting new
3243 connections in the server. Affected file silcd/server.c.
3245 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Added `sender_entry' argument to the function
3248 silc_server_packet_relay_to_channel so that we can check
3249 whether some destination actually belongs to the same route
3250 the sender belongs (ie, we must not resend the packet to the
3251 sender). Affected file silcd/packet_send.[ch].
3253 * Added `servername' field to the SilcClientEntry in the server
3254 to hold the name of the server where client is from. Affected
3255 file is silcd/idlist.h.
3257 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Moved the channel message encrypting in the router betwen
3260 router connections from silc_server_channel_message to the
3261 silc_server_packet_relay_to_channel since we want to check
3262 whether we have anybody channel before encrypting anything.
3263 Affected files silcd/packet_[receive/send].c.
3265 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Fixed the [AdminConnection] server config section to support
3268 multiple entries. Affected file silcd/serverconfig.c.
3270 * Added support into the server to check the validity of the
3271 incoming connection before executing any KE or authentication
3274 * The connection configuration is now saved to the KE and
3275 connection auth protocol contexts and not fetched anymore in
3276 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3278 * The local hosts listenning address and port is also resolved
3279 now when starting the server. We want to have the socket object
3280 to include the real address and port for the listener. Added
3281 new function silc_net_check_local_by_sock into the files
3282 lib/silcutil/silcnet.[ch].
3284 * Fixed a broadcast bug in server -> do not broadcast if we
3287 * Fixed a routing bug. Do not route broadcast packets ever.
3288 Broadcast packets must be processed always and not routed since
3289 they may be destined to some other host than yourself and thus
3290 would get routed without no good reason. Affected file is
3293 * Added function silc_server_config_is_primary_route to check
3294 whether primary router connection has been configured (a router
3295 configuration that we are initiating). If there is not, we
3296 will assume that there is only two routers in the SILC network
3297 and we will use the incoming router connection as our primary
3298 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3300 * Changed the order of the broadcasting. Broadcast _after_ the
3301 packet has been processed not before. Affected file is
3304 * Fixed a [ClientConnection] parsing bug. The port was never
3305 parsed correctly thus resulting to port 0. Affected file
3306 silcd/serverconfig.c.
3308 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3309 argument and did not set the broadcast packet flag. Affected
3310 file silcd/packet_send.c. Fixed same bug in the function
3311 silc_server_send_notify as well.
3313 * If we receive NEW_ID packet for our own ID in the server, ignore
3316 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Removed the nickname from the Private Message Payload.
3321 Updated the code and the protocol specs.
3323 * Updated protocol specs for submitting to the IETF.
3325 * Tweaked the Random Number Generator a bit. Affected file
3326 lib/silccrypt/silcrng.c. Exported a new function
3327 silc_rng_[global]_add_noise which can be used to add more
3330 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Do not parse packets with different timeout when protocol
3333 is active -> may cause problem with rekey. Affected file
3336 * When server receives signoff notify it must not create
3337 new channel key if the client is on any channels since the
3338 sender of the signoff notify will create it.
3340 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Added printing of error messages during SKE protocol from the
3343 failure packet sent by server during SKE. Affected file
3346 * Removed the client's failure_callback handling with timeout
3347 and handle it immediately when received.
3349 * The SKE library returned wrong type in SUCCESS and FAILURE
3350 packets. They must be 32 bit MSB not 16 bit MSB.
3352 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * Ok, rewrote the logic of the re-key and now it seems to work.
3355 I tested it on high traffic with frequent re-keys without
3356 problems. Added hmac_receive (and renamed hmac to hmac_send)
3357 in SilcClientConnection in lib/silcclient/client.h and
3358 in SilcIDListData in silcd/idlist.h. Also, removed the
3359 SilcPacketParserContext's cipher and hmac fields as they are
3360 not needed anymore and actually caused some problems when
3361 the ciphers and hmac's changed underneath the packet parser.
3363 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * If re-key protocol is active then process the incoming packets
3366 synchronously since we must assure that icoming packets encrypted
3367 with the old key is processed before the new keys is set to
3368 use. This is true other packets than for REKEY packets.
3369 Affected file silcd/server.c. The same was done to client library
3370 as well, affected file lib/silcclient/client.c.
3372 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * Fixed bug in client and server to accept the force send if
3375 the packet is send from silc_[server/client]_packet_process
3376 function. Otherwise the packets are never delivered, oops.
3378 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Disable force sending of packets when REKEY protocol is active.
3381 We must assure that no packet is sent directly when rekey is
3382 performed. All packets must be sent through packet queue.
3383 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3384 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3385 function is silc_[server/client]_packet_send_real to check
3388 * Replaced the SIM paths from example config files to
3389 /usr/local/modules. Also, make install creates now
3390 /usr/local/silc/logs directory to hold all the SILC server
3393 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Made the configure.in.pre work on Solaris. Patch by salo.
3397 * Made all ciphers compatible with non-x86 machines. Defined
3398 CBC mode macros into lib/silccrypt/ciphers_def.h.
3400 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Fixed the make install.
3404 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * When MAC computation fails the silc_packet_decrypt returned 0
3407 even though it was supposed to return -1. Fixed this. The
3408 affected file is lib/silccore/silcpacket.c.
3410 * Do not replace the config files in /etc/silc (in make install)
3411 if they already exist. Affected file ./Makefile.am.
3413 * Do not send re-key packets immediately but through packet queue.
3414 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3416 * Changed silc_net_check_host_by_sock to return FALSE if the
3417 IP/DNS could not be resolved. Though, it returns the IP address
3418 now even if it could not resolve it (but returns also FALSE).
3419 Affected file lib/silcutil/silcnet.[ch].
3421 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3423 * Added silc_pkcs_decode_identifier to decode the public key's
3424 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3425 Added also silc_pkcs_free_identifier. Added also new context
3426 SilcPublicKeyIdentifier.
3428 * Added -S option to the silc client. It is used to dump the
3429 contents of the specified public key file.
3431 * Changed the PKCS api to return the public key length when
3432 setting the public key.
3434 * Fixed a fatal bug in the public and private key file loading.
3435 Affected file lib/silccrypt/silcpkcs.c.
3437 * Execute the packet parsing for client with zero (0) timeout
3438 if the protocol is active. Affected file silcd/server.c.
3440 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Made the key generation options to the silcd program. Added
3443 -C option, equivalent to client's option.
3445 * Added new [ServerKeys] config section to the server. It
3446 configures the server's public and private key.
3448 * Defined generic Public Key Payload into the protocol
3449 specification to send specific type of public keys and
3452 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3453 public key or certificate.
3455 * Implemented the GETKEY command to the server and to the
3456 client library and on user interface.
3458 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Made preliminary `make install' work.
3462 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Added SilcServerRekey context into silcd/idlist.h.
3466 * Added the PFS support as defined in the specification to the
3467 SKE protocol. Affected files lib/silcske/*.c.
3469 * Added `ske_group' field to the SilcServerRekey context to hold
3470 the number of the SKE group that is used with PFS in re-key.
3471 Affected file silcd/idlist.h.
3473 * Added PFS re-key support to the server. Affected file is
3476 * Added silc_protocol_cancel to cancel execution of the next
3477 state of the protocol. Affected file is
3478 lib/silccore/silcprotocol.[ch].
3480 * Added the re-key support with and without PFS to the client
3481 library. Re-key is performed once in an hour, by default.
3483 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3484 Added silc_client_rekey_callback and silc_client_rekey_final.
3485 Affected files are lib/silcclient/protocol.[ch] and
3486 lib/silcclient/client.[ch].
3488 * Removed the `hmac_key' and `hmac_key_len' fields from the
3489 SilcClientConnection structure; not needed. Affected file is
3490 lib/silcclient/client.h.
3494 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * Do not ask whether user wants to use the negotiated private key
3497 for private messages, just use it. Affected file is
3498 silc/local_command.c.
3500 * Added `send_enc_key' and `enc_key_len' fields to the
3501 SilcIDListData structure since they are needed in the re-key
3502 phase. Affected file is silcd/idlist.[ch].
3504 * Implemented the simple re-key protocol into the server.
3505 Affected files silcd/server.c and silcd/protocol.[ch]. The
3506 re-key will be performed once in an hour, by default.
3508 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3509 Added silc_server_rekey, silc_server_rekey_callback and
3510 silc_server_rekey_final.
3512 * Removed Tunneled flag from the protocol. Updated the code
3513 and the specifications.
3515 * Adde `pfs' field to the SilcIDListData to indicate whether
3516 the PFS is to be performed in the re-key. Affected file is
3519 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3522 int64 of at least the xintXX size. If void * is less that 4
3523 bytes uint32 * will be used. Defined bool as boolean.
3525 * Changed _ALL_ unsigned long and unsigned int to uint32,
3526 unsgined short to uint16 in the source tree.
3528 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3529 not handle clients that has entry->data.registered == FALSE.
3530 They are not in the network anymore. Affected file is
3533 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Implemented the sending of the SERVER_SIGNOFF notify in the
3536 server. Affected file is silcd/server.c.
3538 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3539 Added also silc_notify_payload_encode_args into the
3540 lib/silccore/silcnotify.[ch].
3542 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3543 Affected file silcd/packet_receive.c.
3545 * Implemented the SERVER_SIGNOFF notify handling in the client
3546 library. Affected file lib/silcclient/client_notify.c. Also,
3547 implemnted the printing of the SERVER_SIGNOFF info to the
3548 application. Affected file silc/client_ops.c.
3550 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3551 if the deleting was successful. Affected file silcd/idlist.[ch].
3553 * Added support for public key authentication in the connection
3554 authentication protocol in the client library. Affected file
3555 lib/silcclient/protocol.c.
3557 * Changed the server's silc_idlist_get_clients_by_* interface
3558 to support already allocated array so that new entries may be
3559 added to pre-allocated array. Affected file silcd/idlist.[ch].
3560 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3561 and command replies.
3563 * All command reply functions in the server now calls the
3564 pending command callback even if error occured. This way the
3565 error will be delivered to the client as well. Affected files
3566 silcd/command.c and silcd/command_reply.c.
3568 * Fixed INFO command to return local server's info if no server
3569 was provided. Affected file lib/silcclient/command.c.
3571 * Removed RESTART command for good. Updated the code and the
3574 * Rewrote parts of the task system. It is a bit simpler now.
3575 Removed unsued task priorities. The affected files are
3576 lib/silcutil/silctask.[ch].
3578 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Moved the USERS printing from the library to the application.
3581 Affected files lib/silcclient/command.c and silc/client_ops.c.
3583 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Added channel key re-key support. The re-key is perfomed
3588 only by the router and is done once in an hour. Added `rekey'
3589 field to the SilcChannelEntry in the server. Affected files
3590 silcd/server.c and silcd/idlist.h.
3592 * Added silc_task_unregister_by_context into the file
3593 lib/silcutil/silctask.[ch].
3595 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Added SILC_UMODE_GONE mode to indicate when the client is not
3598 present in the SILC network. Added also support to the local
3599 command AWAY that will set this mode. Added support of showing
3600 "xxx is gone" in WHOIS command. The USERS command shows the
3601 gone status as well.
3603 * Fixed setting server and router operator privileges in the
3604 server's UMODE command. Affected file silcd/command.c.
3606 * Merged the SKE KE1 and KE2 payloads into one payload. The
3607 new KE payload is equivalent to the old KE2 payload.
3609 Cleaned up the SKE Start Payload parsing. It now uses the
3610 simple buffer unformatting to do the parsing. A lot faster
3613 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3614 to the SKE that is used to indicate whether both of the SKE
3615 parties should perform authentication. By default only the
3616 responder performs authentication. By setting this flag also
3617 the initiator must do authentication. By default it is unset
3618 since in normal SKE case, client to server connection, only
3619 the responder should do authentication. When doing SKE between
3620 two clients both should perform authentication. Updated the
3621 code and the protocol specs.
3623 * A little fix to IDENTIFY command in the server. Search the
3624 client first by hash not nickname. Affected file is
3627 * Fixed the silc_client_close_connection to support closing
3628 the client to client connections wihtout deleting too much
3629 data. Affected file lib/silcclient/client.c.
3631 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3632 are received if protocol used to be active but is not anymore
3633 the application would crash due to NULL pointer dereference.
3634 Affected files silcd/server.c and lib/silcclient/client.c.
3636 * Added `hash' field to the SilcClientConnection to include
3637 the hash function negotiated in the SKE protocol.
3639 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3640 to set the channel founder authentication data. A client can
3641 claim the founder rights later by providing the authentication
3642 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3643 This way the channel founder can regain the channel founder
3644 privileges even it is left the channel. This works only on
3645 local server and the client must be connected to the same
3646 server to be able to regain the founder rights. Updated the
3647 protocol specs accordingly.
3649 Added support to the CMODE command in the client to set the
3650 founder auth data. Read the README to see how to set it.
3652 Added support to the CUMODE command to claim the founder
3653 rights. Read the README to see how to do it.
3655 Added support for the founder authentication to the Channel
3656 Entry in the server. Affected file silcd/idlist.h.
3658 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3659 server's CMODE command. Affected file silcd/command.c.
3661 * Added the following new functions into lib/silccore/silcauth.[ch]:
3662 silc_auth_get_method and silc_auth_get_data.
3664 * The server now saves the remote hosts public key to the
3665 SilcIDListData pointer. Affected file silcd/protocol.c.
3667 * The normal server now does not remove the channel entry from
3668 the cache if the founder authentication data is set. It used
3669 to remove it if the founder was the last one on the channel on
3670 the server and left the channel. The auth data is saved and
3671 if the channel is re-joined later the old entry is used with
3672 the old auth data. Affected files silcd/command_reply.c and
3675 * Removed the `pkcs' field from the SilcIDListData structure
3676 in the server; it is not used. Affected file silcd/idlist.h.
3678 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Fixed packet processing on slow links. Partial packets were
3681 never re-processed because the incoming data buffer was cleared
3682 by the application. Application must not directly clear the
3683 sock->inbuf, the packet processing routines handle it. Fixed
3684 this in client library and in server.
3686 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Fixed the WHOIS and IDENTIFY send reply function to really
3689 check whether to send list or just one entry. Affected file
3692 * Cleaned up the LEAVE command's channel key distribution. The
3693 affected file silcd/command.c.
3695 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3696 can enforce the channel mode as well. In that case the ID
3697 includes the ID of the server. The code now enforces the
3698 mode change if the router have different mode than the server.
3700 * The notify client operation with CMODE_CHANGE notify can now
3701 return NULL client_entry pointer if the CMODE was not changed
3702 by client. Application must check for this.
3704 * Added <Server ID> argument to INFO command to support server
3705 info fetching by Server ID.
3707 * Added silc_server_announce_get_channel_users to get assembled
3708 packets of channel users of the specified channel. Affected
3709 file silcd/server.[ch].
3711 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3712 was freed underneath the ID Cache.
3714 * Re-announce clients when the server received CHANNEL_CHANGE
3715 notify from the router. Affected file silcd/packet_send.c.
3717 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3720 crashed since it did not handle the fact that there is no cipher
3721 called "3" and didn't check the error condition. Now fixed.
3723 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3724 flag. It can be used to send message requests.
3726 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * Implemented the RESTART command in the client.
3730 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3731 notice type messages. Added notice printing to the user
3734 * The channel keys are not re-generated if the channel's mode
3735 is PRIVKEY, ie private key on the channel exists. Affected
3736 files silcd/server.c and silcd/command.c.
3738 * Fixed a little bug in channel message delivery when channel
3739 private keys are set in the server. Affected file is
3740 silcd/packet_send.c.
3742 * Changed the setting on channel->on_channel = TRUE from the
3743 silc_client_save_channel_key to the JOIN command reply. The
3744 key payload is not received if the private channel key is set.
3745 Affected file lib/silcclient/command_reply.c and the
3746 lib/silcclient/client_channel.c.
3748 * When the CMODE_CHANGE notify is sent and the channel private
3749 key mode is removed the channel key must be re-generated in
3750 other cells as well. Added this support for the router in the
3751 silcd/packet_receive.c.
3753 * Added new local command NOTICE to send notice message on
3754 channel. Affected file silc/local_command.[ch].
3756 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Added new local command ME to the client. It is used to send
3759 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3760 some action. Affected file silc/local_command.[ch].
3762 * Changed channel_message and private_message client operations
3763 to deliver the message flags to the application. Added also
3764 the `flags' arguments to the silc_client_send_channel_message
3765 and silc_client_send_private_message functions. Affected file
3768 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Redefined the Private Message Payload to support private message
3771 keys and to support the new private message flags. Updated
3772 the protocol specs. Flags makes it possible to have for example
3773 CTCP style messages.
3775 * Added new type SilcPrivateMessagePayload and defined an API
3776 for it in the lib/silcclient/silcprivate.[ch].
3778 * Tested private message private keys successfully. Tested the
3779 private message key set, unset and list commands with the new
3782 * Redefined the Channel Message Payload to include the channel
3783 message flags (equal with private message flags) to support
3784 for example CTCP style messages.
3786 * Defined some of the message (for channel and private message)
3787 flags. Updated the protocol specs and added the flags to the
3788 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3790 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Added SilcKeyAgreementStatus type to the key agreement routines
3793 to indicate the current status and error if one occured.
3794 The status types are defined in the lib/silcclient/silcapi.h.
3796 * Added new local command KEY that is used to set and unset private
3797 keys for channels, set and unset private keys for private messages
3798 with remote clients and to send key agreement requests and
3799 negotiate the key agreement protocol with remote client. The
3800 key agreement is supported only to negotiate private message keys,
3801 it currently cannot be used to negotiate private keys for channels,
3802 as it is not convenient for that purpose.
3804 * Fixed a minor pending callback setting bug in the function
3805 silc_client_get_client_by_id_resolve, now the function works.
3806 Affected file lib/silcclient/idlist.c.
3808 * Added function silc_net_get_local_port to get local bound
3809 port by socket. Added to lib/silcutil/silcnet.[ch].
3811 * Added `sockets' and `sockets_count' fields to the SilcClient
3812 object. They hold the sockets of the listenning sockets in
3813 the client. Listenning sockets may be for example the key
3814 agreement server. Affected file lib/silcclient/client.[ch].
3815 Added functions the silc_client_add_socket and the
3816 silc_client_del_socket. They are exported to the application
3819 * Added ~./silc/clientkeys to support other client's public keys.
3821 * Renamed verify_server_key client operation to verify_public_key
3822 and added one argument to indicate the type of the connection
3823 (server, client etc.).
3825 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Added silc_server_connection_auth_request to handle the
3828 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3829 silcd/packet_receive.[ch].
3831 * Added silc_server_send_connection_auth_request into the
3832 silcd/packet_send.c to send the connection auth request packet.
3834 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3837 * Fixed the public key authentication in responder side in the
3838 server. The `auth_data' pointer includes the SilcPublicKey
3839 not the path to the public key. Affected file silcd/protocol.c.
3841 * Implemented the public key authentication in the initiator side
3842 in the server. Affected file silcd/protocol.c.
3844 * Removed the [RedirectClient] config section from the server
3845 configuration. Is not needed and I don't want to implement it.
3847 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3849 * Cleaned up the CMODE command in the server. It now works
3850 correctly and supports all the modes defined in the protocol.
3851 Affected file is silcd/command.c.
3853 * Added `hmac_name' field to the SilcChannelEntry in the server
3854 to hold the default HMAC of the channel. It can be set when
3855 creating the channel (with JOIN command). Affected files
3858 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3859 type to indicate the change of the current cipher and hmac
3860 on the channel. Client can safely ignore the <cipher> argument
3861 (if it chooses to do so) since the CHANNEL_KEY packet will
3862 force the channel key change anyway. The <hmac> argument is
3863 important since the client is responsible of setting the new
3864 HMAC and the hmac key into use.
3866 * Fixed the CMODE command in the client library as well.
3868 * Tested CMODE command in router environment successfully.
3870 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3872 * Show the version of the remote client (or server) when connecting
3873 to the server. It is logged to the log file. Affected file
3874 is silcd/protocol.c.
3876 * Fixed the KILLED notify handling in the client library. The
3877 client must be removed from all channels when receiving the
3880 Also, do not remove the client entry when giving the KILL
3881 command but when the KILLED notify is received.
3883 * Removed silc_idlist_find_client_by_nickname from the server.
3884 Not needed anymore. Affected files silcd/idlist.[ch].
3886 * Implemented the CHANNEL_CHANGE notify type handling to the
3887 server. Affected file silcd/server.c.
3891 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Added silc_server_send_notify_invite to send the INVITE
3894 notify between routers.
3896 * Implemented the INVITE command correctly to the server.
3898 * Implemented the INVITE notify type handling in the server.
3900 * Implemented the INVITE command to the client library and on the
3903 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3905 * Added function silc_server_get_client_resolve to find the
3906 client entry by ID from all ID lists and then resolve it
3907 (using WHOIS) if it cannot be found. Affected file is
3910 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3912 * Implemented the BAN command to the client library.
3914 * The JOIN command in the server now checks the invite list
3917 * Changed the silc_command_reply_payload_encode_va and the
3918 silc_command_payload_encode_va to support that if argument is
3919 NULL it ignores and checks the next argument. Affected file
3920 lib/silccore/silccommand.c.
3922 * Added silc_server_send_notify_ban to send the BAN notify
3923 type between routers.
3925 * Chaned the silc_notify_payload_encode to support that if
3926 argument is NULL it ignores and checks the next argument.
3927 Affected file lib/silccore/silcnotify.c.
3929 * Tested ban lists in router environment successfully.
3931 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Implemented BAN command to the server, in silcd/command.[ch].
3935 * Removed the BAN and INVITE_LIST modes from the CMODE command
3938 * Added function silc_string_match to regex match two strings.
3939 Affected files lib/silcutil/silcutil.[ch].
3941 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Redefined parts of the SilcChannelEntry in the server to support
3944 the new ban and invite lists.
3946 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Redefined the INVITE command. The same command can be used to
3949 invite individuals to the channel but also to manage the invite
3950 list of the channel (to add to and remove from the invite list).
3951 Updated the protocol specs.
3953 * Added new command SILC_COMMAND_BAN that can be used to manage
3954 the ban list of the channel. Updated the protocol specs.
3956 * Removed the channel modes: the SILC_CMODE_BAN and the
3957 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3958 in the CMODE command. The equivalent features are now available
3959 using INVITE and BAN commands. Updated the protocol specs.
3961 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3962 in the network about change in the current ban list. The notify
3963 type is not used by the client.
3965 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3966 support the invite lists.
3968 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Added new function silc_string_regexify that converts string
3971 including wildcard characters into regex string that can
3972 be used by the GNU regex library. Added into the file
3973 lib/silcutil/silcutil.[ch].
3975 Added silc_string_regex_combine to combine to regex strings
3976 into one so that they can be used as one regex string by
3977 the GNU regex library. Added into the file
3978 lib/silcutil/silcutil.[ch].
3980 Added silc_string_regex_match to match two strings. It returns
3981 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3983 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Imported GNU regex to the soruce tree into lib/contrib.
3986 Fixed some compiler warning from the regex.c.
3988 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Fixed MOTD command in the server to work in router environment.
3992 * Fixed the MOTD command in the client library to support
3993 the server argument in the command.
3995 * Added `nickname_len' argument to the silc_idlist_add_client
3996 in the server, as the `nickname' argument may be binary data
3999 * Added silc_idlist_get_channels to return all channels from
4002 * Implemented LIST command to the server. Affected file is
4005 * Implemented the LIST command to the client library and on the
4008 * Added [<user count>] argument to the LIST command reply.
4009 With private channels the user count is not shown.
4011 * Updated TODO and README.
4013 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * The client entry's data.registered must be TRUE even with
4016 global client entry on global client list. The data.registered
4017 is used to check whether the client is anymore in the network,
4018 for example with WHOWAS command so it must be valid.
4020 * Fixed the WHOWAS command in the server. It now actually works
4021 in router environment. Added function into silcd/command_reply.c
4022 silc_server_command_reply_whowas_save.
4024 * Added silc_idlist_purge function to the silcd/idlist.c
4025 to periodically purge the ID Cache.
4027 * Fixed INFO command in the server. It works now in router
4028 environment. Added <server name> argument to the INFO command
4029 reply. Updated the protocol specs.
4031 * Fixed minor bug in silc_idcache_purge to not purge if the
4032 expire value is zero.
4034 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4035 they were buggy because of the WHOWAS information.
4037 * Fixed local command MSG to handle the async resolving of
4038 the remote client properly. It used to fail the first MSG.
4039 Affected file silc/local_command.c.
4041 * Added `data_len' field to SilcIDCache context.
4043 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4045 * Update TODO. Todo in commands in the server.
4047 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4049 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4050 used by routers as broadcast packet to inform other routers
4051 about the changed user mode.
4053 Implemented the notify handling in the server. Affected file is
4054 silcd/packet_receive.c. Added the function
4055 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4057 * Added new generic Channel Payload and deprecated the New Channel
4058 Payload. The New Channel Payload is now the generic Channel
4061 * Added new argument `mode' to the silc_server_send_new_channel
4062 as it is required in the Channel Payload now.
4064 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4065 and created a new and real SilChannelPayload to represent the
4066 new generic Channel Payload. Implemented the encode/decode
4067 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4069 * Added silc_server_get_client_channel_list to return the list
4070 of channels the client has joined for WHOIS command reply.
4071 Affected file silcd/server.[ch].
4073 * Implemented the channel list sending in the WHOIS command reply
4074 in server and in the client.
4076 Implemented the channel list displaying on the user interface
4077 as well. Affected file silc/client_ops.c.
4079 * Added silc_channel_payload_parse_list to parse list of Channel
4080 Payloads. It returns SilcDList list of SilcChannelPayloads.
4081 Client for example can use this function to parse the list of
4082 channels it receives in the WHOIS command reply. The caller
4083 must free the list by calling silc_channel_payload_list_free.
4084 Affected files lib/silccore/silcchannel.[ch].
4086 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Added one new argument <user mode> to the WHOIS command reply
4089 to return the mode of the user in SILC. Updated the protocol
4092 Implemented it to the server and client.
4094 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Fixed the mode printing on the user interface on joining.
4097 Affected file silc/client_ops.c.
4099 * Implemented the UMODE command and user modes in general to the
4100 client library and to the user interface.
4102 * Implemented the UMODE command to the server.
4104 * The server now sends UNKNOWN_COMMAND error status if client sends
4105 unknown command. Affected file silcd/command.c.
4107 * All server commands now handle the command identifier the right
4108 way when sending the command reply to the client. The client can
4109 use to identify the command replies with the identifier.
4111 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Added silc_server_get_client_route to resolve the route to
4114 the client indicated by the client ID. Affected file is
4117 * Added silc_server_relay_packet as general function to relay
4118 packet to arbitrary destination. This deprecates functions
4119 like _send_private_message_key, _relay_notify etc. Affected
4120 file is silcd/packet_send.[ch].
4122 Removed silc_server_send_key_agreement,
4123 silc_server_send_private_message_key and
4124 silc_server_packet_relay_notify functions from the file
4125 silcd/packet_send.[ch].
4129 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4130 server. Affected file silcd/packet_receive.[ch].
4132 * Implemented the KILL command to the client. Implemented the
4133 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4134 Affected files lib/silcclient/command[_reply].c and
4135 lib/silcclient/client_notify.c. Implemented the KILL notify
4136 printing in the user inteface.
4138 * Fixed a lot silc_parse_nick memory leaks from the client
4139 library in the file lib/silcclient/command.c.
4141 * Changed the silc_server_send_notify_on_channels's `sender'
4142 argument from SilcSocketConnection to SilcClientEntry to
4143 check the sender as entry and not as connection object and not
4144 to send to the client provided as argument. The affected file
4145 is silcd/packet_send.[ch].
4147 * The notify packets that are destined directly to the client used
4148 to not to be processed by the server. Now changed that and the
4149 server processes all notify packets. After relaying the packet
4150 to the client the notify packet is processed in the server.
4152 * The silc_server_free_client_data now checks whether there is
4153 pending outgoing traffic for the client and purges the data to
4154 the network before removing the client entry.
4156 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4158 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4159 an client is killed from the SILC Network. Updated the protocol
4162 Added new function silc_server_send_notify_killed to the
4163 silcd/packet_send.[ch].
4165 * Added function silc_server_packet_relay_notify to relay notify
4166 packets that are destined directly to a client. In this case
4167 the server does not process the notify packets but merely relays
4168 it to the client. Affected file silcd/packet_send.[ch].
4170 Added also silc_server_packet_process_relay_notify to check
4171 whereto relay the notify. Affected file is
4172 silcd/packet_receive.[ch].
4174 * Implemented the KILL command to the server.
4178 * Added the backup schema desgined last fall to the protocol
4179 specs for everyone to see. The specification is in the
4180 *-spec-xx.txt draft and the packet type definitions for the
4181 backup routers is in *-pp-xx.txt draft. Thusly, added also
4182 new packet type SILC_PACKET_CELL_ROUTERS.
4184 * A big security problem in the implementation discovered. The
4185 signoff of an client did not cause new channel key generation
4186 which it of course should've done. The channel keys must be
4187 always re-generated when client leaves (or signoffs) the channel.
4188 The silc_server_remove_from_channels funtion now handles
4189 the channel key re-generation.
4191 * Added `sender' argument to the silc_server_send_notify_on_channels
4192 to not to send the client provided as argument. Affected file
4193 silcd/packet_send.[ch].
4195 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * Implemented OPER and SILCOPER commands into the server and
4200 * Added silc_auth_verify and silc_auth_verify_data to verify
4201 the authentication directly from the authentication payload.
4202 It supports verifying both passphrase and public key based
4203 authentication. Affected file lib/silccore/silcauth.[ch].
4205 * Added `hash' field to the SilcIDListData structure. It is the
4206 hash negotiated in the SKE protocol. Affected file is
4209 * Slight redesigning of the SilcAuthPayload handling routines.
4210 Do not send SilcPKCS but SilcPublicKey as argument.
4212 * Implemented the public key authentication support to the
4213 serverconfig. The public key is loaded from the provided path
4214 and saved as authentication data to void * pointer. Thus,
4215 changed the unsigned char *auth_data to void *auth_data;
4217 * Fixed SHUTDOWN command to send the reply before the server
4218 is shutdown. :) Affected file silcd/command.c.
4220 * Fixed fatal bug in CONNECT command. The hostname was invalid
4221 memory and server crashed. Affected file silcd/command.c.
4223 * Fixed fatal bug in CLOSE command. The server_entry became
4224 invalid but was referenced later in the command. Affected file
4227 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Fixed fatal bug in failure packet handling. Server ignored
4230 the failure and thus crashed when it came.
4234 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4237 that the command may be executed only once in (about) 2 seconds.
4238 The old SILC_CF_LAG flag is same but allows command bursts up
4239 to five before limiting.
4241 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4242 server code. Various commands now includes the CF_LAG_STRICT
4243 flag to disallow any kind of miss-use of the command.
4245 * Fixed the silc_buffer_unformat to not to allocate any data
4246 if the length of the data is zero. It used to allocate the
4247 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4249 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Changed the format of AdminConnection configuration section
4252 in the server. Added username of the admin to the format.
4253 Affected files silcd/serverconfig.[ch].
4255 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4256 to return admin configuration data by host, username and/or
4259 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Implemented WHOWAS command to the server. Added the functions:
4263 silc_server_command_whowas_parse,
4264 silc_server_command_whowas_send_reply,
4265 silc_server_command_whowas_from_client and
4266 silc_server_command_whowas_from_server
4268 * Added <Client ID> argument to the WHOWAS command reply. Updated
4269 the protocol specs accordingly.
4271 * Implemented WHOWAS command and command_reply to the client
4274 Implemented the WHOWAS printing on the user interface.
4276 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Added new argument to the WHOWAS command reply, the real name.
4279 It is an optional argument. Updated the protocol specs.
4281 * Added SilcIDCacheDestructor callback that is registered when
4282 the SilcIDCache is allocated. The callback is called when
4283 an cache entry in the ID Cache expires, or is purged from the
4284 cache. Added into lib/silccore/idcache.[ch].
4286 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4287 to destruct the client entries when the cache entry expires.
4288 Other ID Cache's in server and in the client library ignores
4291 * If the ID Cache entry's `expire' field is zero then the entry
4292 never expires. Added boolean `expire' argument to the
4293 silc_idcache_add function in the lib/silccore/idcache.[ch].
4294 If it is TRUE the default expiry value is used.
4296 * Added silc_server_free_client_data_timeout that is registered
4297 when client disconnects. By default for 5 minutes we preserve
4298 the client entry for history - for WHOWAS command.
4300 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Added support to the server to enforce that commands are not
4303 executed more than once in 2 seconds. If server receives
4304 commands from client more frequently, timeout is registered
4305 to process the commands. Affected file silcd/command.c.
4306 Added new function silc_server_command_process_timeout.
4308 * Changed NICK_NOTIFY handling in client library to check that
4309 if the client's nickname was changed, so there is no need to
4310 resolve anything from the server.
4312 * Removed error printing from the WHOIS and IDENTIFY commands.
4313 If error occurs then it is ignored silently in the client library.
4314 The application, however, may map the received error to
4315 human readable error string. The application currently maps
4316 the NO_SUCH_NICKNAME error to string.
4318 * Made the command status message public to the application. Moved
4319 them from lib/silcclient/command_reply.c to
4320 lib/silcclient/command_reply.h. The application can map the
4321 received command status to the string with the
4322 silc_client_command_status_message function.
4324 * Added check to the server to check that client's ID is same
4325 as the Source ID in the packet the client sent. They must
4328 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Added dist-bzip hook to the Makefile.am to make bzip2
4331 compressed distributions.
4333 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Server now enforces the maximum length for the nickname and
4336 the channel as protocol specification dictates. 128 bytes for
4337 nickname and 256 bytes for channel name.
4339 * Moved the WHOIS printing to the application. The client libary
4340 does not print out the WHOIS information anymore, the application
4341 must do it. Renamed silc_client_command_reply_whois_print to
4342 the silc_client_command_reply_whois_save.
4344 The client's idle time is also sent to the application now, and
4345 the idle is shown on screen.
4347 * Added silc_client_command_reply_identify_save to save the
4348 received IDENTIFY entries.
4350 * Do not check for channel private keys in message sending and
4351 reception if the channel does not have the PRIVKEY mode set.
4352 Affected file lib/silclient/client_channel.c.
4354 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4357 just surfaced after chaning the JOIN procedure.
4359 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Added silc_client_get_clients_by_list to get client entries
4362 from Client ID list, that is returned for example by JOIN
4363 and USERS command replies. The application should use this
4364 function for example when JOIN command reply is received to
4365 resolve the clients already on the channel (library does not
4366 do that anymore as USERS command reply is not used in the JOIN
4367 procedure anymore). Affected files lib/silcclient/silcapi.h and
4368 lib/silcclient/idlist.c.
4370 * JOIN command reply and USERS command reply returns now SilcBuffer
4371 pointers instead of unsigned char pointers when returning
4372 the client list and mode list.
4374 * Added <Client ID> argument to the JOIN command reply, mainly
4375 for the server to identify for which client the command was
4376 originally sent. Updated protocol specs accordingly.
4378 * Added SilcDlist private_key pointer to the SilcChannelEntry
4379 in the client to support the channel private keys. Affected
4380 file is lib/silcclient/idlist.h.
4382 * Added SilcChannelPrivateKey argument to the function
4383 silc_client_send_channel_message so that application can choose
4384 to use specific private ke if it wants to. If it is not provided,
4385 the normal channel key is used, unless private keys are set.
4386 In this case the first (key that was added first) is used
4387 as the encryption key.
4389 * Implemented the support for channel private key handling.
4390 Implemented the following functions:
4392 silc_client_add_channel_private_key,
4393 silc_client_del_channel_private_keys,
4394 silc_client_del_channel_private_key,
4395 silc_client_list_channel_private_keys and
4396 silc_client_free_channel_private_keys
4398 Affected file lib/silcclient/client_channel.c.
4400 * Added the support for the private keys in the channel message
4401 sending and encryption and in the message reception and
4402 decryption. Affected funtions are
4403 silc_client_send_channel_message and silc_client_channel_message.
4405 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Added SKE's key verify callback to the client library's
4408 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4410 * Removed the statement that server (or router) must send USERS
4411 command reply when joining to the channel so that the client
4412 knows who are on the channel. Instead, the client list and
4413 client's mode list is now sent in the JOIN command reply to the
4414 client who joined channel. This is better solution.
4416 * Added function silc_server_get_users_on_channel and function
4417 silc_server_save_users_on_channel to the silcd/server.[ch].
4419 * Removed function silc_server_command_send_users from the
4422 * Do not show topic on the client library anymore. The topic is
4423 sent in the command reply notify to the application and the
4424 application must show the topic now.
4426 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Added client searching by nickname hash into the IDENTIFY and
4429 WHOIS commands in the server as they were clearly missing from
4430 them. Affected file is silcd/command.c.
4432 * Fixed a bug in private message receiving in the client library.
4433 The remote ID was freed and it wasn't supposed, now it is
4436 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Minor fix to the channel payload; allocate the data area, as it
4439 needs to be of specific length.
4441 * If the key agreement port is zero then the operating
4442 system will define the bound port. Affected files are
4443 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4445 * Added new function silc_channel_payload_decrypt into the file
4446 lib/silccore/silcchannel.[ch].
4448 * Moved the channel message etc, check from silc_packet_decrypt
4449 to applications. The library calls now a generic
4450 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4451 when the packet is either normal or special. This was done to
4452 allow more wide range of checking that was not allowed when
4453 the code was in library. Now applications can do virtually any
4454 checks to the packet and return to the library the decision how
4455 the packet should be processed. Affected files are
4456 lib/silccore/silcpacket.[ch].
4458 Added silc_server_packet_decrypt_check to the server and
4459 silc_client_packet_decrypt_check to the client library.
4461 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4462 to send with specified source and destination information.
4464 * Channel message delivery between routers was broken after the
4465 channel key distribution was fixed earlier. The channel key
4466 was used be to distributed to other routers as well which is not
4467 allowed by the protocol. Now this is fixed and channel keys
4468 really are cell specific and the channel message delivery between
4469 routers comply with the protocol specification.
4471 * Fixed various commands in server to check also the global list
4472 for the channel entry and not just the local list. The affected
4473 file silcd/command.c.
4475 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Added assert()s to buffer formatting and unformatting routines
4478 to assert (if --enable-debug) when error occurs. Affected
4479 file: lib/silcutil/silcbuffmt.c.
4481 * Changed to auto-reconnect to check whether the remote host is
4482 router and register the re-connect timeout if it is. It used
4483 to check that whether we are normal server, but router must do
4484 auto-reconnect with another router as well. Affected file
4487 * Removed the [<key len>] option from CMODE command as the cipher
4488 name decides the key length, nowadays. See the defined ciphers
4489 from the protocol specification.
4491 * Added [<hmac>] option to the CMODE command to define the HMAC
4492 for the channel. Added SILC_CMODE_HMAC channel mode.
4494 * Added [<hmac>] option for the JOIN command so that user can
4495 select which HMAC is used to compute the MACs of the channel
4498 * Added Hmac field to the Channel Message Payload. The integrity
4499 of plaintext channel messages are now protected by computing
4500 MAC of the message and attaching the MAC to the payload. The
4501 MAC is encrypted. Now, it is clear that this causes some
4502 overhead to the size of the packet but rationale for this is that
4503 now the receiver can verify whether the channel message decrypted
4504 correctly and also when private keys are set for the channel the
4505 receiver can decrypt the packet with several keys and check from
4506 the MAC which key decrypted the message correctly.
4508 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4509 lib/silccrypt/silccipher.[ch].
4511 * Added silc_hash_len to return the digest length into the
4512 lib/silcrypt/silchash.[ch].
4514 * Rewrote parts of Silc Channel Payload interface in the
4515 lib/silccore/silcchannel.[ch]. The encode function now also
4516 encrypts the packet and parse function decrypts it.
4518 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Fixed a minor formatting bug in the SKE's key material processing.
4521 It actually might have processed the keys wrong way resulting
4524 * Redefined the mandatory HMAC algorithms and added new algorithms.
4525 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4526 and hmac-md5 truncated to 96 bits. The mandatory is now
4527 hmac-sha1-96. Rest are optional (including the one that used
4528 to be mandatory). Rationale for this is that the truncated HMAC
4529 length is sufficient from security point of view and can actually
4530 make the attack against the HMAC harder. Also, the truncated
4531 HMAC causes less overhead to the packets. See the RFC2104 for
4534 * Added new [hmac] configuration section. The SKE used to use
4535 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4536 is of course wrong. The official names that must be proposed in
4537 the SKE are the ones defined in the protocol specification
4538 (hmac-sha1-96 for example). The user can configure any hmac
4539 using any hash function configured in the [hash] section. At
4540 least, the mandatory must be configured.
4542 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4544 * Added HMAC list to the SKE proposal list. It has now both
4545 hash algorithm list and HMAC list. This makes the protocol
4546 incompatible with previous versions. The SKE now seems to work
4547 the way it is supposed to work, for the first time actually.
4549 * Defined plain Hash algorithms to the protocol specification.
4552 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Implemented support for key agreement packets into the server.
4555 Added functions silc_server_key_agreement and
4556 silc_server_send_key_agreement. Other than these functions,
4557 server has nothing to do with this packet.
4559 * Added support for private message key packets into the server.
4560 Added functions silc_server_private_message_key and
4561 silc_server_send_private_message_key.
4565 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4566 called in the protocol's final callback instead in the END
4567 protocol state. This makes a little more sense and in the same
4568 time in client we can use the same protocol routines for normal
4569 key exchange and to key agreement packet handling as well.
4571 * Added to both client's and server's KE protocol context the
4572 SilcSKEKeyMaterial pointer to save the key material. We will
4573 bring the key material to the protocol's final callback by doing
4574 this. The final callback must free the key material.
4576 * Added SKE's packet_send callback into client's KE protocol
4577 context so that the caller can choose what packet sending function
4578 is used. This way we can use different packet sending when
4579 doing normal SKE when doing key agreement packet handling (in
4580 the key agreement packet handling we do not want to encrypt
4583 * Implemented the responder side of the key agreement routines
4584 in the client. The client can now bind to specified port and
4585 accept incoming key negotiation. The key material is passed
4586 to the application after the protocol is over.
4588 * Implemented the processing of incoming Key Agreement packet
4589 in the client. Added function silc_client_key_agreement to
4592 * Implemented the intiator side of the key agreement routines
4593 in the client. The client can now initiate key agreement with
4594 another remote client. The key material is passed to the
4595 application after the protocol is over.
4597 * Created client_keyagr.c to include all the key agreement
4600 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4601 SILC_TASK_CALLBACK except that it is not static.
4603 * Created client_notify.c and moved the Notify packet handling
4604 from the client.[ch] into that file.
4606 * Created client_prvmsg.c and moved all private message and
4607 private message key routines from the client.[ch] into that file.
4609 * Create client_channel.c and moved all channel message and
4610 channel private key routines from the client.[ch] into that file.
4612 * Changed silc_client_get_client_by_id_resolve to resolve with
4613 WHOIS command instead of IDENTIFY command, in the file
4614 lib/silclient/idlist.c.
4616 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Implemented the SKE's responder side to the Client library.
4620 * When FAILURE is received to the protocol do not trust it
4621 blindly. Register a timeout to wait whether the remote closes
4622 the connection as it should do it, only after that process the
4623 actual failure. This was changed to both client and server.
4625 * Added client_internal.h to include some of the structures
4626 there instead of client.h in lib/silcclient/.
4628 * Added function silc_task_unregister_by_callback to unregister
4629 timeouts by the callback function.
4631 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Some "Incomplete WHOIS info" errors has been appearing on the
4634 log files. Took away the entry->userinfo check from WHOIS
4635 reply sending. The entry->userinfo is now " " if client did not
4636 provide one. I thought this was fixed earlier but something
4637 is wrong still. Let's see if the error still appears.
4639 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Fixed a minor bug in the login when the channel key is
4642 re-generated in the server. It used to generate the key in
4643 wrong order and thus caused problems in the channel traffic.
4645 * Fixed a minor bug in channel key distsribution after
4646 KICK command. The key was not sent to the router even though
4649 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * Added silc_ske_process_key_material_data as generic routine
4652 to process any key material as the SILC protocol dictates. The
4653 function is used by the actual SKE library but can be used by
4654 applications as well. This relates to the private message keys
4655 and the channel private keys since they must be processed the
4656 same way the normal SILC session keys. The protocol dictates
4657 this. Affected files: lib/silcske/silcske.[ch].
4659 Added also silc_ske_free_key_material to free the
4660 SilcSKEKeyMaterial structure.
4662 * Defined silc_cipher_set_key function to set the key for
4663 cipher without using the object's method function. The affected
4664 files: lib/silccrypt/silccipher.[ch].
4666 * Implemented silc silc_client_add_private_message_key,
4667 silc_client_add_private_message_key_ske,
4668 silc_client_del_private_message_key,
4669 silc_client_list_private_message_keys and
4670 silc_client_free_private_message_keys functions in the
4673 Added functions silc_client_send_private_message_key to send
4674 the Private Message Key payload and silc_client_private_message_key
4675 to handle incoming Private Message Key payload.
4677 * Added Cipher field to the Private Message Key payload to set
4678 the cipher to be used. If ignored, the default cipher defined
4679 in the SILC protocol (aes-256-cbc) is used.
4681 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Removed lib/silcclient/ops.h file.
4685 Redefined parts of the SILC Client Library API. Created new
4686 file silcapi.h that deprecates the ops.h file and defines the
4687 published Client Library API. Defined also private message key
4688 API and channel private key API into the file.
4690 This is the file that the application must include from the
4691 SILC Client Library. Other files need not be included by
4692 the application anymore.
4694 * Added new key_agreement client operation callback and also
4695 defined the Key Agreement library API for the application.
4697 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4700 is used by clients to request key negotiation between another
4701 client in the SILC network. If the negotiation is started it
4702 is performed using the SKE protocol. The result of the
4703 negotiation, the secret key material, can be used for example
4704 as private message key.
4706 Implemented the Key Agreement payload into the files
4707 lib/silccore/silauth.[ch].
4709 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4711 * Redefined ciphers for the SILC protocol. Added some new ciphers
4712 and defined the key lengths for the algorithms. Changed the
4713 code accordingly. The default key length is now 256 bits.
4715 * Fixed SKE key distribution function silc_ske_process_key_material
4716 when the key length is more than 128 bits. The default key
4717 length in SILC is now 256 bits.
4719 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4720 to indicate unsupported algorithm.
4722 * Renamed rijndael.c to aes.c and all functions as well.
4724 * Fixed a long standing channel key setting bug in client library.
4725 Weird that it has never surfaced before.
4727 * Fixed bug in channel deletion. If the entire channel is removed
4728 then it must also delete the references of the channel entry
4729 from the client's channel list as the client's channel entry and
4730 the channel's client entry share same memory.
4732 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Implemented CONNECT and SHUTDOWN commands in the client.
4736 * Implemented CLOSE command to the client.
4738 * Added the function silc_idlist_find_server_by_name into the
4739 files silcd/idlist.[ch].
4741 Added the function silc_idlist_find_server_by_conn into the
4742 files silcd/idlist.[ch].
4744 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * DIE command was renamed to SHUTDOWN. Updated the both code
4749 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4750 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4752 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4755 * Added function silc_server_create_connection function to create
4756 connection to remote router. My server implementation actually
4757 does not allow router to connect to normal server (it expects
4758 that normal server always initiates the connection to the router)
4759 so the CONNECT command is only good for connecting to another
4762 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4765 or some other client was kicked from the channel.
4767 Implemented the handling of the notify type to both client
4770 Implemented silc_server_send_notify_kicked to send the KICKED
4771 notify. It is used to send it to the server's primary router.
4773 * Implemented the KICK command into server and client.
4775 * Added `query' argument to the silc_idlist_get_client function
4776 to indicate whether to query the client from server or not if
4779 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4780 to indicate that the client is not channel founder.
4784 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Removed the rng context from SilcPacketContext structure and
4787 changed that the packet routine uses the Global RNG API.
4789 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Added support for quit message that client can "leave" on the
4792 channel when it quits the SILC. It is ditributed inside the
4793 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4795 Added silc_server_free_client_data that will take the
4796 signoff message as argument.
4798 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4800 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Updated parts of the protocol specification to keep it up
4805 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4808 payloads in one packet.
4810 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4811 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4812 use now the new List flag.
4814 * Also deprecated the following packet types: REPLACE_ID,
4815 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4817 * Added list support for Notify packet in server.
4819 * Added silc_server_send_notify_channel_change to send the
4820 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4821 the silc_server_send_replace_id.
4823 * Added silc_server_send_notify_nick_change to send the
4824 NICK_CHANGE notify type. Deprecates the function
4825 silc_server_send_replace_id.
4827 * Added silc_server_send_notify_join to send the JOIN notify type.
4828 Deprecates the function silc_server_send_new_channel_user.
4830 * Added silc_server_send_notify_leave to send LEAVE notify type.
4831 Deprecates the function silc_server_send_remove_channel_user.
4833 * Added silc_server_send_notify_cmode and
4834 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4835 types. Deprecates the silc_server_send_set_mode function.
4837 * Added SERVER_SIGNOFF notify type to indicate that server has
4838 quit. This means that all clients on the channel from that
4839 server will drop. This can be also used when netsplit happens.
4841 Deprecated REMOVE_ID packet type since it is not needed anymore
4844 Added silc_server_send_notify_server_signoff to send the
4845 SERVER_SIGNOFF notify type. Deprecates the function
4846 silc_server_send_remove_id.
4848 Added also silc_server_send_notify_signoff to send the
4849 SIGNOFF notify type.
4851 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4852 SILC protocol from this day on. Changed the protocol
4853 specification as well.
4855 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4856 notify type. It is used between routers to notify about
4857 topic changes on a channel.
4859 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4862 * Partly updated the protocol specification to comply with the
4863 changes now made. It is still though a bit outdated.
4865 * The JOIN notify type now takes one extra argument <Channel ID>.
4866 The packet used to be destined to the channel but now the
4867 JOIN type may be sent as list thus it is impossible to
4868 destine it to any specific channel. By adding this argument
4869 it is again possible.
4871 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Added CREDITS file. The CHANGES and CREDITS file will appear
4874 in the distribution as well.
4876 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4879 types in the server's silcd/packet_receive.c.
4881 * Implemented CMODE and CUMODE to work in router environment.
4883 * Fixed minor encoding and decoding buglet from the
4884 lib/silccore/silcmode.c.
4886 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4889 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4891 * Changed all SilcConfigServer* and silc_config_server* to
4892 SilcServerConfig* and silc_server_config*, respectively.
4895 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Associated the ID (client or server ID) to the Authentication
4898 Payload to avoid any possibility of forging. Updated the
4899 protocol specification and the code accordingly.
4901 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4903 * The RSA key length is now save to the RsaKey context in the
4904 key generation process in lib/silccrypt/rsa.c. The key length
4905 is now used to figure out the maximum size of the block allowed
4906 to be encrypted/signed.
4908 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4909 is equivalent to the silc_mp_mp2bin but does not allocate any
4912 * Changed silc_mp_mp2bin API to take length argument. If it is
4913 non-zero then the buffer is allocated that large. If zero, then
4914 the size is approximated using silc_mp_sizeinbase, which however
4917 * Created Global RNG API which is global RNG that application can
4918 initialize. After initializing, any routine anywhere in the
4919 code (including library) can use RNG without allocating a new
4920 RNG object. This was done to allow this sort of use of the
4921 RNG in code that has no chance to allocate RNG object. All
4922 applications currently allocate this and many routines in the
4923 library use this. Affected file lib/silccrypt/silcrng.[ch].
4925 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4926 it to use the Global RNG API.
4928 * Defined Authentication Payload into protocol specification that
4929 is used during SILC session to authenticate entities. It is
4930 used for example by client to authenticate itself to the server
4931 to obtain server operator privileges.
4933 Implemented this payload into the lib/silccore/silcauth.[ch].
4934 Implemented also routines for public key based authentication
4935 as the new protocol specification dictates.
4937 Moved definitions of different authentication methods from
4938 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4940 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4941 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4942 silc_pkcs_verify_with_hash functions into the file
4943 lib/silccrypt/silcpkcs.[ch].
4945 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * The client entry's userinfo pointer must be always valid.
4948 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4949 will fail since it requires the userinfo. Now, the userinfo
4950 is allocated as "" if actual userinfo does not exist. Actually,
4951 it must exist and it is totally Ok to drop client connections
4952 that does not announce the userinfo. However, we will make
4953 this workaround for now.
4955 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4956 to return the remote port by socket.
4958 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4961 SILC_SERVER_PENDING_EXEC and added an new macro
4962 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4963 data or when error occurs while processing the pending command.
4965 Added new argument `destructor' into silc_server_command_pending
4966 and to the SilcServerCommandPending object. This destructor is
4967 now called after calling the pending callback or if error occurs
4968 immediately. If error occurs the actual pending callback won't
4969 be called at all - only the destructor. The destructor may be
4970 NULL if destructor is not needed.
4972 All this applies for client library code as well. Similar
4973 changes were made there as well for the pending commands.
4975 In the client, the application must now allocate the
4976 SilcClientCommandContext with the silc_client_command_alloc
4979 * Added reference counter to the SilcServerCommandContext. Added
4980 function silc_server_command_alloc and silc_server_command_dup
4983 Same type of functions added to the client library for the same
4986 * Removed the cmd_ident from IDListData away since it is now
4987 global for all connections. It is the command identifier used
4988 in command sending and with pending commands. The affected file
4991 * Added reference counter to the SilcSocketConnection objecet to
4992 indicate the usage count of the object. The object won't be
4993 freed untill the reference counter hits zero. Currently only
4994 server uses this, and client ignores it. The client must be
4995 set to use this too later. The affected files are
4996 lib/silccore/silcsockconn.[ch]. Added also the function
4997 silc_socket_dup to increase the reference counter.
4999 This was mainly added because it is possible that the socket
5000 is removed underneath of pending command or other async
5001 operation. Now it won't be free'd and proper DISCONNECTING
5002 flags, etc. can be set to avoid sending data to connection that
5003 is not valid anymore.
5005 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5006 the connection. After that it sets SILC_SET_DISCONNECTED.
5007 It is, however, possible that the socket data is not still freed.
5008 The silc_server_packet_process now checks that data is not
5009 read or written to connection that is DISCONNECTED. The socket
5010 get's freed when the reference counter hits zero.
5012 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Changed the client operation API: channel_message operation's
5015 `sender' is now the client entry of the sender, not the nickname
5016 and the `channel' is the channel entry, not the channel name.
5018 In the private_message operation the `sender' is now also the
5019 client entry of the sender not the nickname.
5021 Affected file is lib/silcclient/ops.h and all applications
5022 using the client operations.
5024 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Moved the calling of ops->connect() from connect_to_server_final
5027 into receive_new_id functin since that is the point when the
5028 client is actually allowed to send traffic to network. The
5029 affected file is lib/silcclient/client.c.
5031 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5034 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5035 (if needs broadcasting) instead of broadcasting the packets one
5036 by one which would make a burst in the network traffic.
5038 * Added `broadcast' argument to the functions in silcd/server.[ch]
5039 silc_server_create_new_channel[_with_id] to indicate whether
5040 to send New Channel packet to primary router.
5042 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Added new function into the silcd/server.[ch] files:
5045 silc_server_create_new_channel_with_id to create new channel with
5046 already existing Channel ID.
5048 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5049 lib/silccore/silcpacket.h. This packet is used t send list of
5050 Set Mode payloads inside one packet. Server uses this to set
5051 the modes for the channels and clients on those channels, that it
5052 announced to the router when it connected to it. The protocol
5053 specification has been updated accordingly.
5055 * The silc_server_new_channel did not handle the packet coming
5056 from normal server as it normally does not send that. However,
5057 when it announces its channels it does send it. Implemented
5058 the support for that.
5060 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5061 into the file lib/silccore/id.h.
5063 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Fixed memory leaks in the functions silc_idlist_del_client,
5066 silc_idlist_del_channel and silc_idlist_del_server in the file
5067 silcd/idlist.c. All of those leaked like a sieve.
5069 * Fixed some small memory leaks in the client's function
5070 silc_client_notify_by_server.
5072 * Added functions into silcd/server.c: silc_server_announce_clients,
5073 silc_server_announce_channels and silc_server_announce_server.
5074 These functions are used by normal and router server to announce
5075 to its primary router about clients, channels and servers (when
5076 router) that we own. This is done after we've connected to the
5079 These functions effectively implements the following packet types:
5080 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5081 and SILC_PACKET_NEW_ID_LIST.
5083 * Added new functions into the silcd/packet_receive.[ch]:
5084 silc_server_new_id_list, silc_server_new_channel_list and
5085 silc_server_new_channel_user_list to handle the incoming
5086 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5088 * Added support of changing Channel ID in the function
5089 silc_server_replace_id. If the server that announces a channel
5090 to the router already exists in the router (with same name but
5091 with different Channel ID), router is responsible to send
5092 Replace ID packet to the server and force the server to change
5093 the Channel ID to the one router has.
5095 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5096 client that the Channel ID has been changed by the router. The
5097 normal server sends this to the client. Client must start using
5098 the new Channel ID as the channel's ID.
5100 Implemented handling of this new type into lib/silcclient/client.c
5101 into the function silc_client_notify_by_server.
5103 * Added new function silc_idlist_replace_channel_id into the files
5104 silcd/idlist.[ch] to replace the Channel ID.
5106 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Call silc_server_command_identify_check always when processing
5109 the IDENTIFY command in silcd/command.c
5111 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5114 send keepalive packets. The packet can be sent by clients,
5115 servers and routers.
5117 Added function silc_socket_set_heartbeat into the file
5118 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5119 If not set, the heartbeat is not performed. The actual
5120 heartbeat is implemented in the low level socket connection
5121 library. However, application is responsible of actually
5124 Added silc_server_send_heartbeat to send the actual heartbeat
5125 packet into silcd/packet_send.[ch]. Server now performs
5126 keepalive with all connections.
5128 * Added silc_task_get_first function into lib/silcutil/silctask.c
5129 to return the timeout task with shortest timeout. There was a bug
5130 in task unregistration that caused problems. TODO has been
5131 updated to include that task system must be rewritten.
5133 * The client library will now resolve the client information when
5134 receiving JOIN notify from server for client that we know but
5135 have incomplete information.
5137 * Rewrote parts of silc_server_remove_from_channels and
5138 silc_server_remove_from_one_channel as they did not remove the
5139 channel in some circumstances even though they should've.
5141 * Encryption problem encountered in server:
5143 The LEAVE command used to send the Channel Key packet to the
5144 router immediately after generating it. However, the code
5145 had earlier sent Remove Channel user packet but not immediately,
5146 ie. it was put to queue. The order of packets in the router
5147 was that Channel Key packet was first and Remove Channel User
5148 packet was second, even though they were encrypted in the
5149 reverse order. For this reason, MAC check failed. Now, this
5150 is fixed by not sending the Channel Key packet immediately but
5151 putting it to queue. However, this is more fundamental problem:
5152 packets that are in queue should actually not be encrypted
5153 because packets that are sent immediately gets encrypted
5154 actually with wrong IV (and thus MAC check fails). So, packets
5155 that are in queue should be encrypted when they are sent to
5156 the wire and not when they put to the queue.
5158 However, the problem is that the current system has not been
5159 designed to work that way. Instead, the packet is encrypted
5160 as soon as possible and left to the queue. The queue is then
5161 just purged into wire. There won't be any fixes for this
5162 any time soon. So, the current semantic for packet sending
5165 o If you send packet to remote host and do not force the send
5166 (the packet will be in queue) then all subsequent packets to the
5167 same remote host must also be put to the queue. Only after the
5168 queue has been purged is it safe again to force the packet
5171 o If you send all packets immediately then it safe to send
5172 any of subsequent packets through the queue, however, after
5173 the first packet is put to queue then any subsequent packets
5174 must also be put to the queue.
5176 Follow these rules and everything works fine.
5178 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Added new function silc_server_remove_clients_by_server to
5181 remove all client entries from ID list when the server connection
5182 is lost. In this case it is also important to invalidate all
5183 client entires as they hold the invalid server entry. This
5184 fixes fatal bug when server has lost connection and will reconnect
5187 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Made some sanity checks to silc_server_daemonise like to check
5190 whether the requested user and group actually exists.
5192 * Added sanity check to SKE's silc_ske_responder_finish to check
5193 that the public and private key actually is valid.
5195 * Invalidate the client's nickname when receiving Replace ID
5196 packet and the Client ID is being replaced. This means that the
5197 server will query the nickname if someone needs it (client)
5200 * Sort the ID Cache in client library when the ID Cache data
5201 has changed (needs sorting).
5203 * Do not allow for SILC client to create several connections to
5204 several servers. The client does not support windows right now
5205 and generating multiple connections causes weird behaviour.
5207 Irssi-silc client does support windows and can handle several
5208 connections without problems, see: www.irssi.org and SILC plugin.
5210 * Fixed some places where client was added to the IDList. The
5211 rule of thumb is following (in order to get everything right):
5212 If the client is directly connected local client then the
5213 `connection' argument must be set and `router' argument must be
5214 NULL to silc_idlist_add_client function. If the client is not
5215 directly connected client then the `router' argument must
5216 bet set and the `connection' argument must be NULL to the
5217 silc_idlist_add_client function.
5219 * The funtion silc_server_packet_send_local_channel actually did
5220 not check whether the client was locally connected or not. It
5221 does that now. Fixed a bug related to LEAVE command.
5223 * Fixed Remove Channel User payload parsing bug in server's
5224 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5226 * The server's silc_server_save_channel_key now checks also the
5227 global ID list for the channel as it might not be in the local
5228 list. Fixed a bug related to LEAVE command.
5230 * Is this the end of the [<unknown>] buglet that has been lurking
5231 around for a long time? A little for loop fix in server's
5232 silc_server_command_whois_parse that is used by both IDENTIFY
5233 and WHOIS command. At least, this was a clear bug and a cause
5234 of one type of [<unknown>] buglet.
5236 * WHOIS and IDENTIFY commands call the function
5237 silc_server_command_[whois/identify]_check function even if
5238 we are not router server.
5240 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Added --with-gmp configuration option. If set the GMP
5243 is always compiled in the SILC source tree. If not set then
5244 it is checked whether the system has the GMP3 installed. If
5245 it has then the GMP won't be compiled (the system's headers
5246 and library is used), if it doesn't have it then the GMP is
5247 compiled in the SILC source tree.
5249 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Changed RSA private exponent generation to what PKCS #1
5252 suggests. We try to find the smallest possible d by doing
5253 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5254 not security fix but optimization.
5256 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Added new config entry [Identity] to fork the server and run
5259 it as specific user and group. A patch from Bostik.
5261 * Imported Dotconf configuration library into lib/dotconf.
5262 This will be used to create the SILC configuration files later.
5263 It will appear in the distsribution after this commit.
5265 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * A big code auditing weekend happening. Auditing code for
5268 obvious mistakes, bugs and errors. Also, removing any code
5271 Removed files for being obsolete:
5273 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5274 inline in the file lib/silcutil/silcbuffer.h)
5276 o lib/silcutil/silcbufutil.c (the header has inline versions)
5278 Changed code to fix possible error conditions:
5280 o The buffer formatting routines now check that the destination
5281 buffer really has enough space to add the data. This applies for
5282 both buffer formatting and unformatting
5283 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5284 unformatting was changed to accomodate following rules:
5285 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5286 sent to the function while XXX_*STRING will not allocate or copy
5287 the data into the buffer. Instead it sets the pointer from the
5288 buffer into the pointer sent as argument (XXX_*STRING used to
5289 require that the pointer must be allocated already). This change
5290 makes this whole thing a bit more consistent and more optimized
5291 (note that the data returned in the unformatting with XXX_*STRING
5292 must not be freed now). The routines return now -1 on error.
5294 o Tried to find all code that use buffer_format and buffer_unformat
5295 and added return value checking to prevent formatting and
5296 especially unformatting errors and possible subsequent fatal
5299 o Changed ske->x and ske->KEY to mallocated pointers in
5300 lib/silcske/silcske.h. Fixed possible data and memory leak.
5302 o Added return value checking to all *_parse* functions. Fixed
5303 many memory leaks as well.
5305 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5306 so that buffer overflows would not happen. All code now also
5307 checks the return value as it can fail.
5309 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5311 * Added reconnection support to server if the normal server looses
5312 its connection to the router (for example if router is rebooted).
5313 The server performs normal reconnection strategy implemented
5314 to the server. Affected file silcd/server.c.
5316 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Added new packet type SILC_PACKET_SET_MODE that is used to
5319 distribute the information about changed modes (for clients,
5320 channels and clients channel modes) to all routers in the
5321 network. Updated the protocol specification accordingly.
5323 Added functions into silcd/packet_send.c and
5324 silcd/packet_receive.c: silc_server_send_set_mode,
5325 silc_server_set_mode.
5327 Added new files silcmode.[ch] into lib/silccore that implements
5328 the encoding and decoding of Set Mode Payload. Added new type
5329 SilcSetModePayload. Moved the definitions of different modes
5330 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5332 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5334 * Oops, a little mistake in server's connection authentication
5335 protocol. The protocol is not ended with FAILURE but with
5336 SUCCESS if the authentication is Ok. :) Affected file is
5339 * Implemented NICK_CHANGE notify handling in server in the file
5340 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5341 the local clients on the channel. After the changing nickname
5342 in router environment snhould work and the [<unknown>] nickname
5343 should appear no more.
5345 The silc_server_replace_id function that receives the Replace ID
5346 payload now sends the NICK_CHANGE notify type also in the file
5347 silcd/packet_receive.c
5349 * Changed WHOIS and IDENTIFY command to support the maximum amount
5350 of arguments defined in protocol specs (3328 arguments). This
5351 fixed a bug that caused problems when there were more than three
5354 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5356 * Added extra parameter, command identifier, to the
5357 silc_client_send_command so that explicit command identifier
5360 Changed that ID list routines uses specific command identifier
5361 when sending WHOIS/IDENTIFY requests to the server so that they
5362 can be identified when the reply comes back.
5364 Affected files lib/silcclient/command.[ch],
5365 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5367 * Added `sender' argument to silc_server_packet_send_to_channel
5368 to indicaet the sender who originally sent the packet to us
5369 that we are now re-sending. Ignored if NULL. Affected file
5370 silcd/packet_send.[ch].
5372 * Added some server statistics support in silcd/server_internal.h
5373 SilcServerStatistics structure and around the server code. Also
5374 send some nice statistics information when client is connecting
5377 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * Fixed channel ID decoding in server's JOIN command reply in
5380 silcd/command_reply.c
5382 * Fixed braodcasting of replace ID payload to not to send it if
5383 we are standalone server in silcd/packet_receive.c.
5385 * Fixed all channel message sending routines to not to send
5386 packets to clients that has router set, since they are routed
5387 separately in the same function earlier. Affects file
5388 silcd/packet_send.c and all channel packet sending functions.
5390 * In USERS reply, res_argv[i] are not allocated, the table
5391 is allocated. Thus changed that free the table, not its
5394 * In server's whois_check and identify_check if the client is
5395 locally connected do not send any WHOIS commands - they are not
5398 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Fixed some minor bugs in client when sending WHOIS command. The
5401 arguments was in wrong order.
5403 * Removed statis function add_to_channel from server in
5404 silcd/command.c that was previously used with the joining but
5407 * Tested USERS command in router environment successfully with two
5408 routers, two servers and two clients.
5410 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Reorganized the USERS command and command reply in client library
5413 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5414 When the command is given by user we register a pending command
5415 callback that will reprocess the command after the reply has been
5416 received from the server. When reprocessing the packet we then
5417 display the information. Thus, the USERS information is displayed
5418 now in the command callback instead of in the command reply
5419 callback. The processing of the command is same as previously
5420 when server has sent the command reply in the JOINing process.
5422 * Added to USERS command in silcd/command_reply.c to join the client,
5423 we didn't use to know about, to the channel after we've created
5424 a client entry for it. Also, for clienet we did know already still
5425 check whether it is on the channel or not and add it if not.
5427 * Removed silc_server_command_join_notify as the function and its
5430 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5432 * Changed the client's pending command handling to the same as the
5433 server's pending command handling. It is also now possible to
5434 execute command reply functions from other command reply
5435 function as the function callbacks for commands and command
5436 replies are one and same. The pending commands are not static
5437 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5438 in client connection context. Thus, pending commands are server
5439 connection specific as it is convenient.
5441 Changed the function silc_client_command_pending and
5442 silc_client_command_pending_del and added new function
5443 silc_client_command_pending_check. Removed the
5444 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5447 * Added cmd_ident, current command identifier, to the client
5448 connection context in lib/silcclient/client.h to keep track on
5449 command identifiers used in command sending. Client's command reply
5450 function handling now supports the mandatory command identifiers.
5452 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5453 funtions in client to fully support pending command callbacks.
5455 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5456 as one of the arguments to the application in the command reply
5459 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5460 before first releasing SILC but came back. Now it is removed again
5461 and should come back nomore. The FORWARDED flag was used only
5462 by the JOINing procedure by forwarding the command packet to router.
5463 Now, the JOINing procedure has been changed to more generic (due
5464 to various router environment issues) and FORWARDED is not needed
5465 anymore for anything. The protocol specification is yet to be
5468 Now, removed silc_server_packet_forward from server and the flag
5469 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5471 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Renamed NAMES command to USERS command. The NAMES was named that
5474 due to historical reasons. Now it is renamed. Also, rewrote
5475 parts of the USERS command. The nickname list is not sent anymore
5476 by the server. Only Client ID and mode lists are sent in the USERS
5477 command. Changed this also to the protocol specification.
5479 The client now resolves the names and stuff after it receives
5480 the USERS list from the server when joining to the channel.
5482 * WHOIS and IDENTIFY commands has been changed to support multiple
5483 Client ID's per command. One can now search for multiple users
5484 in the network by sending only one WHOIS or IDENTIFY command.
5485 Changed the code and the protocol specifications.
5487 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5488 uses silc_server_command_whois_parse to parse the request. */
5490 * If normal server, do not parse the WHOIS and IDENTIFY requests
5491 before sending it to the router. Saves some time.
5493 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Fixed JOIN command on client library. Wrong number of arguments
5496 used to crash the client.
5498 * Added silc_server_channel_has_global function to check whether
5499 channel has global users or not.
5501 * Added silc_server_channel_has_local function to check whether channel
5502 has locally connected clients on the channel.
5504 * The silc_server_remove_from_one_channel now checks whether the
5505 channel has global users or not after given client was removed from
5506 the channel. It also checks whether the channel has local clients
5507 on the channel anymore. If it does not have then the channel entry
5508 is removed as it is not needed anymore.
5510 * The silc_server_notify now checks on JOIN notify whether the joining
5511 client is one of locally connected or global. If it is global then
5512 the channel has now global users on the channel and that is marked
5513 to the channel entry. Also, it now saves the global client to
5514 global list who is joining and JOINs it to the channel. This is
5515 for normal server, that is.
5517 Changed silc_server_send_notify_on_channel,
5518 silc_server_packet_relay_to_channel and
5519 silc_server_packet_send_to_channel check if we are normal server
5520 and client has router set (ie. global client) do not send the
5521 message to that client, as it is already routed to our router.
5523 * Implemented LEAVE notify type handling in silc_server_notify
5526 * Tested LEAVE command in router environment successfully. Tested
5527 with two routers, two servers and two clients.
5531 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5533 * Implemented SIGNOFF notify type handling in silc_server_notify
5536 * silc_server_remove_id now removes the client entry from all channels
5537 it has joined and thusly sends SIGNOFF notify type.
5539 * Rewrote the NAMES list generation in server by removing two excess
5540 loops. The lists are created now inside one loop.
5542 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * silc_server_remove_channel_user checks now also global list
5545 for channel and client.
5547 * silc_server_new_channel_user checks now both local and global
5548 list for channel and client. Fixed a bug in client id decoding.
5549 Used to decode wrong buffer.
5551 * silc_server_channel_message checks now both local and global
5552 list for channel entry.
5554 * Tested channel joining (hence JOIN) in router environment
5555 successfully. Tested with two routers, two servers and two
5558 * Tested channel message sending in router environment successfully.
5560 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * Added silc_server_save_channel_key into server.[ch] to save the
5563 received channel key in Channel Key payload processing. It is
5564 also used in JOIN command reply handling.
5566 Equivalent function silc_client_save_channel_key added into
5567 client.[ch] into client library.
5569 * Changed JOIN command reply to send information whether the channel
5570 was created or not (is existing already) and the channel key
5571 payload. Changed protocol specs accordingly.
5573 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5574 the request was sent by ID and not by nickname. Crashed on
5577 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5580 now correctly save the received data.
5582 * silc_server_free_sock_user_data now notifies routers in the
5583 network about entities leaving the network.
5585 At the same time implemented functions silc_server_remove_id
5586 and silc_server_send_remove_id to receive and send REMOVE_ID
5587 packets. The packet is used to notify routers in the network
5588 about leaving entities. The ID removed will become invalid in
5591 * Added function silc_idlist_del_server into server. Removes and
5592 free's server entry from ID list.
5594 * silc_server_private_message function now checks, if we are router,
5595 that the destination ID really is valid ID, naturally.
5597 * In router when NEW_ID packet is received (for new client) the
5598 hash of the Client ID is saved in the ID Cache but the
5599 client->nickname is set to NULL, instead of putting the hash
5602 IDENTIFY command now also checks that client->nickname must be
5603 valid. If it is not if will request the data from the server who
5604 owns the client. Added new function
5605 silc_server_command_identify_check.
5607 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5608 to set the command to already allocated Command Payload.
5610 * Tested private message sending in router environment with two
5611 routers, two servers and two clients. Fixed minor bugs and now
5614 * Fixed segfault from client's NAMES command. Used to crash if
5617 * Forwarded packets must not be routed even if it is not destined
5618 to the receiver. Changed server code comply with this.
5620 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5622 * Added `require_reverse_mapping' boolean value to ServerParams
5623 structure. If TRUE (not default) the server will require that
5624 the connecting host has fully qualified domain name.
5626 If the reverse mapping is not required and hostname could not be
5627 found the IP address is used as hostname.
5629 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Implemented version string checking to both client and server.
5632 The check is incomplete currently due to the abnormal version
5633 strings used in development version of SILC.
5635 * Changed all command functions in server to use the new
5638 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5640 * Changed char *data to unsigned char *data in ID Cache system to
5641 support binary data as ID Cache data. Changed code to support
5642 binary data in lib/silccore/idcache.c.
5644 * Renamed silc_server_packet_relay_command_reply to
5645 silc_server_command_reply as it is normal packet receiving
5646 function. Rewrote the function to accept command replys for
5647 servers and not only for clients.
5649 * Mark remote router always as registered server if we are connecting
5650 to it. Otherwise, commands sent by the router to us are ignored.
5652 * All ID List find routines now returns the ID Cache Entry pointer
5653 as well if requested.
5655 * WHOIS command works now in router environment, tested with two
5656 routers, two servers and two clients.
5658 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5659 in router environment (as it is almost equivalent to WHOIS) but
5660 hasn't been tested thoroughly. Added new functions:
5662 silc_server_command_identify_parse
5663 silc_server_command_identify_send_reply
5664 silc_server_command_identify_from_client
5665 silc_server_command_identify_from_server
5667 * Disabled route cache adding because adding two different ID's with
5668 same IP replaces the old cache entry thus giving wrong route.
5669 The entry->router->connection is always the fastest route anyway
5670 so route cache may not be needed. Of course, new routes maybe
5671 established after receiving the ID when the entry->router->connection
5672 might not be anymore the most optimal.
5674 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Add route cache for received ID for fast routing.
5678 * Added silc_server_packet_route to route received packet on router
5679 that is not destined to us.
5681 * Renamed silc_server_get_route to silc_server_route_get.
5683 * Added id_string and id_string_len fields into SilcServer to
5684 include encoded ServerID for fast comparing without excess
5685 encoding of the ID's.
5687 * Cleaned up WHOIS command on server side. Added following static
5690 silc_server_command_whois_parse
5691 silc_server_command_whois_check
5692 silc_server_command_whois_send_reply
5693 silc_server_command_whois_from_client
5694 silc_server_command_whois_from_server
5696 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5697 arguments in command replies. All command functions should be
5698 updated to use this macro.
5700 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5702 * Minor typo fixes on command reply handling on server.
5704 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Added silc_server_command_add_to_channel internal routine to add
5707 the client to the channel after router has created the channel and
5708 sent command reply to the server.
5710 * Added generic silc_server_send_command to send any command from
5713 * Use static buffer with ID rendering instead of duplicating data.
5715 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5717 * Fixed a channel user mode bug when joining to a channel server gave
5718 everybody channel founder rights, oops.
5720 * We mark ourselves as the router of the incoming server connection
5721 if we are router ourselves. This way we can check in some packet
5722 sending functions whether it is locally connected server. For
5723 incoming router connections we put NULL.
5725 * For router sending packets locally means now always sending the
5726 packet cell wide; to local clients and local servers. For normal
5727 server sending packet locally means sending it to only local
5730 * Fixed the JOIN command to really work in router environment. If the
5731 channel is created it is always created by the router. Router is
5732 also responsible of making the initial joining to the channel,
5733 sending JOIN notify to the sending server and distributing
5734 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5735 does not exist server doesn't do anything else but forward the
5736 command to the router which performs everything.
5738 * Added silc_server_send_channel_key function to send the Channel Key
5741 * Added silc_server_create_channel_key to create new channel key. The
5742 channel key is now re-generated everytime someone joins or leaves
5743 a channel, as protocol dictates. Note: channel->key_len is the
5746 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5748 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5749 packet_receive.[ch] to separate packet sending and receiving
5750 routines. The server.[ch] now includes everything else including
5751 actual packet processing (writing and reading data) and other
5754 Renamed silc_server_private_message_send_internal to
5755 silc_server_send_private_message. The routine is still though
5756 used only to relay private messages as server does not send
5757 private messages itself.
5759 Renamed silc_server_new_channel to silc_server_create_new_channel
5760 and added new function sicl_server_new_channel that handles the
5761 incoming New Channel packet. Added also new sending function
5762 silc_server_send_new_channel to send New Channel Payload.
5764 * Added new function silc_server_notify to process incoming notify
5765 packet to the server/router. Server may then relay the notify
5766 to clients if needed.
5768 * Added new function silc_server_new_channel_user to process incoming
5769 New Channel User packet. Router will redistribute the packet and
5770 send JOIN notify to its local clients and locally connected servers
5771 if needed. Normal server will send JOIN notify to its local client
5772 on same channel when received this packet. Added also corresponding
5773 sending function silc_server_send_new_channel_user to sent the
5776 * Added boolean route argument to send_notif_to_channel and
5777 packet_send_to_channel functions to attempt to route the packet
5778 if it is TRUE and send only locally if it is FALSE.
5780 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * silc_server_replace_id now broadcasts the received replace ID
5783 packet if it is not broadcast packet already. The router must
5784 broadcast to inform other routers about changed ID.
5786 * Added backpointer to server's router into SilcServer context in
5787 silcd/server_internal.h.
5789 * Fixed silc_server_packet_broadcast to send correct broadcast
5792 * The channel key is now distributed to the local client as soon
5793 as it is received from the router (in router environment) so that
5794 no other packet may be sent for the channel until client has
5797 * silc_server_remove_channel_user now broadcasts the received
5798 Remove Channel User packet if it is not broadcast packet already.
5799 The router must broadcast to inform other routers about removed
5802 * Added users field into SilcPacketContext that is a reference count
5803 of the context. One can increase the reference count by calling
5804 silc_packet_context_dup which is now changed to just increase the
5805 reference count instead of duplicating the data. The reference
5806 count is decresed by calling silc_packet_context_free that will
5807 free the data after the reference count hits zero.
5809 For now on the packet context and everything allocated into it
5810 (including the raw packet from network) must be freed by calling
5811 the new silc_packet_context_free function. Added also new function
5812 silc_packet_context_alloc that must be used now to allocate the
5813 context. This also means that if a routine is asynchronous from
5814 silc_[client/server]_packet_parse_type the packet context must
5815 be duplicated by calling silc_packet_context_dup. Otherwise it
5816 gets free'd after silc_[client/server]_packet_parse_type returns.
5817 Also, one must remember that if packet is duplicated then its
5818 reference count must be decresed by calling the free function as
5819 many times as it was duplicated.
5821 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5822 from both client and server.
5824 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5826 * Made joining to a channel working in router environment.
5828 * Cleaned up JOIN command on server side and create function
5829 silc_server_command_join_channel internal routine to make the
5832 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Changed silc_command_pending list to SilcDList. Also, added
5835 `ident' field to SilcServerCommandPending structure to identify
5836 the reply and to call correct callback.
5838 Added silc_server_command_pending_check function to replace the
5839 corresnponding macro. The silc_command_pending list is not
5842 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5843 to set identifier to previously allocated Command Payload. It
5844 is used to set identifier for command when resending Command
5847 * Added silc_command_payload_encode_payload to encode Command
5848 Payload buffer from SilcCommandPayload structure.
5850 * Added silc_argument_payload_encode_payload to encode Argument
5851 payload buffer from SilcArgumentPayload structure.
5853 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Changed WHOIS command to support router connection on server side.
5856 The whois request is always sent to router unless the server is
5857 standalone server. After server has received the reply from the
5858 router will it send the reply to the client.
5860 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5861 broadcast received broadcast packet. The function is used only
5862 by router. The broadcast packet is always sent to the router's
5865 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5866 render given ID to printable string, for log files for example.
5868 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Made basic router to router connections working. At least they
5871 can now connect to each other but nothing really works the way
5872 they are supposed - yet.
5874 * Added new initiator token to RouterConnection configuration
5875 file in silcd/serverconfig.[ch]. It is used to tell whether we
5876 are the initiator to the remote router or whether we'll expect
5877 the other end to connect.
5879 * Moved registering of listener task to silc_server_init, hence
5880 the server starts listenning as soon as it is run, even if it
5881 does not have connections to other routers. Let's see how well
5884 * Changed default connection retry timeouts for more suitable in
5887 * Removed cipher and such arguments from silc_idlist_add_client
5888 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5889 Added new function silc_idlist_add_data to add the keys and stuff
5892 * Added SilcIDListData structure and added it to SilcClientEntry
5893 and SilcServerEntry as their first field in the structure. This
5894 way we can explicitly cast the ID entries to the SilcIDListData
5895 structure and get common data for the entries. In past, we had
5896 to first check what type of connection it is and then cast it to
5897 correct ID entry type. Now, we can directly cast the opaque
5898 pointer to the SilcIDListData (no matter what ID entry it actually
5899 is) and get the data needed.
5901 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5903 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5904 in some circumstances even if threre were timeout tasks, though not
5905 IO tasks, but tasks anyway. Now fixed.
5907 * Defined SilcServerConnection structure to hold connection specific
5908 stuff about directly connected servers and routers. The definition
5909 is currently in silcd/server_internal.h. I thought about having
5910 a bit more important role fro this struct but for now it is used
5911 only when connecting to other server (or router actually).
5913 * Added connecting retry support in server when connecting to
5914 router(s). The retry feature implement exponential backoff
5915 algorithm. Also, added SilcServerParams structure to hold default
5916 parameters for server. For now, it include these retry settings
5917 and are hard coded. After server is moded to be as Silc Server
5918 Library this structure will be more important.
5920 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Changed client librarys channel->clients table to SilcList and
5923 changed code accordingly.
5925 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5927 * Changed client's channel table to SilcList and changed code
5928 accordingly. Also changed SilcChannelClientEntry to include back-
5929 pointer to the channel so that client entry can use that structure
5930 as list as well and we have fast cross-reference to the channel.
5931 This change dramatically decreased the complexity of channel
5932 handling with client entry and vice versa (removed one extra
5933 loop when searching for channel entry from many functions).
5935 * Changed server->sim from table to SilcDList and changed code
5938 * NAMES command can now be used from user interface. It will show
5939 the user list on the channel, neatly.
5941 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5942 Code now saves realname of the user if it becomes available.
5944 * Renamed configure.in to configure.in.pre and made ./prepare
5945 script to automatically add correct version string to
5946 configure.in which it creates from configure.in.pre.
5948 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * NAMES command reply now shows users mode with the nickname when
5953 * Moved silc_client_ch[u]mode[_char] functions from
5954 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5955 place sucks, they are utility functions and should be in some
5958 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5960 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5963 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Added TRQ (efficient deque and list library) into lib/trq. This is
5968 a very good list library that is currently used in the SILC. Defined
5969 SilcList API over the library because I didn't like the API very
5970 much. See lib/trq/silclist.h for the API and examples of how to
5971 use the API. Fixed various places in the code to use the new
5972 SilcList API. The SilcList is meant for lists that has a structure
5973 already defined as a list. It is not suitable to add just some
5974 context to the list (in TRQ, the context is the list actually).
5976 So, I defined SilcDList that can be used for the purpose where
5977 predefined list structure does not exit. This can be used as
5978 such list. Now some context just can be added to the SilcDList.
5979 Currently this list is not used in the SILC just yet, though there
5980 are a lot places where this can replace dynamically allocated
5981 tables and I will fix these places, later, to use SilcDList.
5982 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5983 and use TRQ internally).
5985 Also fixed some annoying warning messages that the original TRQ
5986 code generated. Also minor changes to TRQ's Makefile.in.
5988 * Added support for querying by Client ID to both WHOIS and
5989 IDENTIFY commands into server, as required by the protocol.
5991 * Removed method function pointers from SilcBuffer structure. They
5992 weren't used to anything and just increased the context size for
5993 no good reason. This change also made silc_buffer_alloc and
5994 silc_buffer_free functions inline functions.
5996 * Disabled command flooding detection support until it's fixed so
5997 that it accepts commands in but does not execute them more than once
6000 * Added silc_net_localhost(), to return local hostname, into
6001 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6002 that must be initialized before calling silc_client_init.
6004 * Added new function: silc_server_send_notify_on_channels to send
6005 notify messages to all channels client has joined. It is assured
6006 that the message is sent only once per client.
6008 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6009 lib/silcutil/silcutil.[ch] as silc_format function. The new
6010 function is generic and is used by server as well, not only by
6011 the logging routines.
6013 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6014 the provided version string was not acceptable. Added new function:
6015 silc_ske_check_version into lib/silcske/silcske.h. The function
6016 must be implemented by the application (client or server) and it
6017 does not reside in the SKE library. The function checks the version
6018 string remote end sent.
6020 * Added back pointers (to opaque context and to SilcSocketConnection)
6021 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6023 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6024 duplicate packet context structure.
6026 * Changed `notify' client operation to send same arguments as client
6027 receives from server except for ID's. ID's are mapped to correct
6028 ID entry and that is returned. Also, if channel entry is not sent
6029 by server but the notify is for channel the channel entry is sent
6030 to application (otherwise application doesn't know that it is for
6031 channel (library gets it from packet's Destination ID)).
6033 * Added silc_client_remove_from_channels into client library to
6034 remove a client from all channels it has joined to. Used when
6035 received SIGNOFF notify from server. Added also new function
6036 silc_client_replace_from_channels to replace old ID entry with
6037 new ID entry on all channels. Used when received NICK_CHANGE
6040 * Fixed ID Cache list handling in silc_idlist_get_client in
6041 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6042 to get (or query) client by ID.
6044 * Updated TODO list.
6046 * Added connection authentication status message defined by the
6047 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6048 support for these into the code in client and server side.
6050 * Added generic function silc_client_send_command to send any command
6051 with variable argument list. Application should use this function
6052 to send commands if the command functions provided by the library
6053 does not suite for the application's user interface needs.
6055 * Added new `failure' client operation. Application is notified about
6056 received failure packet if client is executing a protocol. In this
6057 case the protocol's execution has failed.
6059 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6060 is required by the protocol.
6062 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6063 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6066 * Added status flag to SilcSKE object to indicate realtime status
6067 of the SKE protocol.
6069 * Application receives now exactly same command reply arguments as
6070 the library receives from server. However, if ID is received the
6071 corresponding ID entry is returned to the application (eg. Client
6072 ID is mapped to correct SilcClientEntry entry and that is returned).
6073 Changed command_reply client operation due to this change.
6075 * Changed all ID's in commands and in command replys as ID Payloads.
6076 Change affected both client and server side codes.
6078 All ID's sent in SILC network (with execption of ID's in SILC
6079 Packet header) are sent in ID Payload to support variable length
6082 * Server now notifies nick changes and notifies all clients on
6083 the channels about the new nickname (about the new Client ID,
6086 * Implemented CMODE command to change channel modes. Supports all
6087 channel modes defined by the protocol specs except ban and invite
6088 lists. (Also, private channel key mode is supported but support for
6089 setting private channel key in client is missing, thus, this mode
6090 has no effect on client side (except that server requires that the
6091 client uses private channel key and normal channel traffic does not
6094 Also, invite mode works per se, but INVITE command does not work
6095 yet correctly, so you can set channel as invite only channel but
6096 inviting clients to the channel does not work (it is yet to be
6097 thought what's the best way to do it).
6099 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6100 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6101 Implemented CUMODE command to change user's mode on the channel.
6102 Supports all modes defined by the protocol specs.
6104 * Added NAMES command reply to return users modes on the channel.
6106 * Removed unnecessary and slow ciphers from lib/silccrypt.
6108 * Set SO_KEEPALIVE option to connection sockets by default.
6110 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6112 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6113 redefined the Notify Payload into protocol specs.
6115 * Added silc_id_payload_parse_id to get ID directly from raw
6118 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6120 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6121 accept searching by Client ID as well.
6123 * Added support for LEAVE and SIGNOFF notify types in client library.
6125 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6126 to parse ID Payload from raw data.
6128 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Added flags parameter into silc_ske_assemble_security_properties
6131 function in lib/silcske/silcske.[ch].
6133 * Changed notify client operation to fit better for notify messages
6134 sent by server. The notify payload received from server is now
6135 passed to the application (after parsing it to SilcNotifyPayload).
6136 It is application's responsibility to retrieve the arguments
6137 from the payload and show the message the way it wants. The message
6138 sent by server is implementation specific.
6140 * Changed public keys to comply with the protocol specification.
6141 Old public keys are not supported anymore and are not compatible.
6143 * Removed nickname from Channel Payload as the latest draft removed
6144 it. The client must resolve the nickname from the NAMES command
6145 reply received when it joined the channel.
6147 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6149 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6151 * Fixed some errors in protocol specification drafts.
6153 * Created lib/silccore/silcnotify.c to implement Notify Payload
6154 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6155 generic payloads described by protocol specifications. The file
6156 includes implementations for ID Payload and Argument Payload.
6158 * Changed Command Payload implementation to use the new Argument
6159 Payload. Changed command_xxxx_payload to command_payload_xxxx
6160 to comply with SILC coding conventions.
6162 * Added suppport for Argument Payload handling in Notify Payload
6163 implementation as protocol requires it. Added the new support
6164 into server and client lib as well.
6166 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6168 * Added support for multiple nicknames on same channel. [n] is
6169 added locally to the nickname if there are more than one same
6170 nicknames on the channel.
6172 * Server now sends all nicknames that matched WHOIS request.
6173 Client also shows the list received from server.
6175 * Added TOPIC command to client side. User can now set and show
6176 current topic on channel.
6178 * Added MOTD command to client and server. Also, server sends the
6179 motd when client connects to the server.
6181 * Changed version strings to comply ISO 8601.
6183 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6185 * Fixed protocol error handling in client library. It should now
6186 cope even if the SKE fails for some reason.
6188 * Made new protocol specification drafts for submitting to IETF.
6190 * Implemented TOPIC command to server in silcd/command.c.
6192 * Added two new notify types into lib/silccore/silcnotify.h:
6193 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6194 notify nickname change and topic setting/change on a channel.
6196 * API change of command_reply operation in client library. The
6197 application gets now the status type received from server as well.
6199 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6201 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6203 * Cras fixed and optimized the packet handling even further and
6204 it should work now. Minor change to the prototype of function
6205 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6207 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6209 * Added new function into lib/silcutil/silcschedule.[ch]:
6210 silc_schedule_with_fd to select() a specified fd. The function
6211 returns after timeout expires or data arrives or goes. The
6212 function is used by packet routines to wait that all data is
6213 received from network.
6215 * Fixed data reading from network in lib/silccore/silcpacket.c.
6216 The code now assures that all data is read from the fd and then
6217 continues packet processing. This was a bug fix since the code
6218 used to drop some data in some circumstances.
6220 * Added new function into lib/silcclient/client.[ch]:
6221 silc_client_start_key_exchange to start key exchange after
6222 connection has been established to server. The code internally
6223 now uses this funtion but its main purpose was to provide it
6224 for applications that perform their own connecting. After
6225 application has created a connection it merely calls this
6226 function to start the key exchange between client and server.
6227 The library takes care of everything else after that.
6229 Updated also lib/silcclient/README to explain the usage of
6232 * Do not send to application information that connection has
6233 been established. Application gets notified it by connect
6236 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6238 * Applied cras's patch to add silc_schedule_one function. The
6239 function runs scheduler once and returns.
6241 * Fixed the scheduler after cras messed it up. The timeout
6242 handling works now as it's supposed to work.
6244 * Added into lib/silccore/ silcnotify.h to include notify
6245 message types support. Changed silc_server_send_notify*
6246 functions, in server.[ch], to support those new notify types.
6247 Added the support for the notify types into client library,
6248 as well. Added new notify client operation into ops.h in
6251 * Changed silc_server_packet_send_to_channel to send normal
6252 packets instead of just channel message packets. The function
6253 is now used to send the notify packets to channels. It is not
6254 used to send channel message packets anymore, as server never
6257 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6258 va_arg()s as it seems to require it nowadays. I guess, if SILC
6259 is compiled with older va_arg() the new code should work anyway.
6261 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6263 * Splitted core library. Core library (lib/silccore) includes
6264 now only SILC protocol specific core (and common) components.
6265 Created new utility library (lib/silcutil) that includes more
6266 generic purpose stuff. The stuff for util library was taken
6267 from the old core library. This was minor and easy split.
6269 * Created SILC Client Library (lib/silcclient) that includes
6270 implementation of the SILC client without user interface. This
6271 was major move from silc/ directory. The code has been changed
6272 so that it is transparent towards the user interface. The
6273 silc/ directory includes now the same user interface as before
6274 and it uses the new client library. Read lib/silcclient/README.
6275 Basicly, the client library performs everything else related
6276 to SILC except user interface handling. Also, configuration
6277 files are considered to be part of user interface and library
6278 does not handle them.
6280 This change also changed a lot of structures, function naming etc.
6281 Most important change was that SilcClientWindow object was
6282 renamed to SilcClientConnection in the client library. Created
6283 also new file lib/silcclient/ops.h. Also added new files
6284 silc/local_command.[ch] and silc/client_ops.[ch].
6286 All these changes were made to make it easier for user interface
6287 designers to create what ever user interface for the SILC client
6290 It is also expected that the server will be moved to lib
6291 directory as well and SILC Server Library will be created;
6292 sometimes in the future.
6294 * Removed Local commands from lib/silccore/silccommand.h as
6295 they are application specific and new client library does not
6296 handle any of those anymore.
6298 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6299 old client implementation in silc/.
6301 * Added support for callback functions in SILC_LOG_* macros.
6302 Application can now set its own callbacks that will be called
6303 instead of using the default functions that will always print
6304 the debug messages to stderr (or stdout). Also, debugging can
6305 now be disabled by setting silc_debug to FALSE and re-enabled by
6306 setting it to TRUE. Note, that logging will still work even
6307 if debugging is disabled.
6309 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6310 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6311 silc_log_reset_debug_callbacks.
6313 * To enable debugging in silc client one must give now -d
6314 option on command line.
6316 * Changed silc_schedule_init to automatically allocate task queues
6317 if they are not allocated before calling it.
6319 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6321 * Added GMP 3.1 into math library.
6323 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6325 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6326 a channel in SILC network. The packet is used by servers and
6327 routers to notify other routers that user has left a channel.
6328 This little feature was missing until now. Added the feature
6329 to protocol specification as well.
6331 Added functions: silc_server_send_remove_channel_user and
6332 silc_server_remove_channel_user into server.[ch].
6334 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6335 lib/silccore/silcpacket.h. However, they are not implemented
6338 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Fixed joining to a channel and sending channel messages
6341 between server and router. The channel message sending should
6342 now work inside a cell.
6344 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6346 * Fixed the private message sending between server and router.
6347 The private message sending should now work inside a cell.
6349 * Added silc_server_replace_id into server.[ch] to replace
6350 existing ID in the SILC network.
6352 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6353 and silc_idlist_replace_server_id into idlist.[ch] in server.
6355 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6357 * Fixed the server to server connections. Server can again now
6358 connect to router. Router to router connections probably does
6361 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6363 * Added dynamic protocol registering support. Now protocols can
6364 registered and unregistered on the fly. Patch by cras.
6366 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * Added lib/contrib directory to hold routines that some platforms
6369 don't have but are needed by SILC.
6371 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6372 into lin/contrib to provide getopt() and getopt_long() for
6373 those who don't have it.
6375 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6377 * Added AWAY command to client. When away message is set and
6378 client receives a private message packet the client automatically
6379 replies to the sender with the away message.
6381 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6382 bug seemed to be the cause of recent problems when compiling
6385 * Added version detection support to SKE protocol specification
6386 and added the new changes to the SKE implementation as well.
6387 There were other minor changes in the SKE protocol as well.
6389 Many changes in lib/silcske/silcske.[ch] and in
6390 lib/silcske/payload.[ch].
6392 * Added ^U functionality, clear input line. Patch from cras.
6394 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6396 * Mainly small bugfixes on core library. Fixed some debugging
6397 logging and buffer overflow in silclog.c.
6399 * Updated config.sub and config.guess on the distribution tree.
6401 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Added command lagging support in server. Client may execute
6404 commands now only once in two seconds.
6406 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6408 * Optimized packet reception. MAC computation and checking is now
6409 also more optimized. A lot previously duplicated code is now
6410 used as generic by both client and server.
6412 * Fixed key pair generation in clientutil.c
6414 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6416 * Added into lib/silccore/silcbufutil.[ch] new function;
6417 silc_buffer_realloc.
6419 * Moved generic packet sending/encryption functions to
6420 lib/silccore/silcpacket.[ch] from client and server. Some
6421 rewriting of the functions.
6423 * Moved all generic packet reception/decryption functions to
6424 lib/silccore/silcpacket.[ch] from client and server. The
6425 packet processing is now much cleaner in both client and server.
6426 These were major changes in both client and server.
6428 * Created many common functions in server to do packet sending.
6429 Previously code were duplicated a lot, this has been removed
6432 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * Rewrote major parts of the ID cache system. Don't know
6435 whether it is better now or not but at least the API is more
6438 * Major rewrite on ID cache stuff on client because of the ID
6439 cache API changes. Added idlist.c to client.
6441 * Also major rewrite on ID cache stuff on server as well.
6442 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6443 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6444 in hand, instead they are all put into the ID cache system now.
6445 All server_idlist_* routines uses ID cache now instead of
6446 traversing its own lists (those lists does not exist anymore).
6447 SilcIDList though still exists. Also, SilcXXXEntry's are
6450 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Finally made the SKE implementation compliant to the protocol
6453 specification. All mp integers are now binary encoded as
6454 opposed being HEX encoded.
6456 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6459 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6460 functions: silc_[encode/decode]_pem. Also added function
6461 silc_encode_pem_file to PEM encode with newlines ('\n') for
6464 * SILC public keys are now encoded either PEM or binary. Same
6465 option is for private keys as well. By default private keys
6466 are binary encoded and public keys PEM encoded. Silly HEX
6467 encoding were removed.
6469 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6470 function to create fingerprints.
6472 * Fixed a bug in SHA1; does not change the original data anymore.
6474 * Partly implemented INFO command on client and server side.
6475 Fixed CLEAR command. Changes to SERVER command; show current
6476 server(s) when giving command without arguments. Added
6477 VERSION command to client.
6479 * Added check to server that unregistered connections cannot
6480 execute commands (unless it is specificly allowed).
6482 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Fixed screen refresh.
6486 * Fixed channel joining bug from client. On some circumstances
6487 client tried to join to a channel it had already joined.
6489 * Added public key verification process into client's protocol.c.
6490 The client now verifies the public key from user and saves
6491 it into ~./silc/serverkeys/ directory.
6493 Added into: clientutil.[ch]: silc_client_verify_server_key.
6495 * Changed SKE protocol's silc_ske_initiator_finish function
6496 to accept callback function that verifies the received public
6497 key. Removed old silc_ske_verify_public_key function.
6499 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6501 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6502 silc_pkcs_private_key[_data]_set.
6504 * Made the password and public authentication more cleaner in
6505 server's protocol.c.
6507 * Removed historic and obsolete protocol `channel_auth' from
6508 both client and server.
6510 * Removed wrong way of sending command status messages from
6511 server to client in server's command.c. The old way violated
6512 protocol specification.
6514 Changes to silccore/silccommand.[ch]: removed
6515 silc_command_encode_status_payload -> not needed anymore,
6516 changed silc_command_encode_payload_va to accept extra
6517 argument on variable argument list. The argument type must
6518 now be provided to the function. Also, added new function:
6519 silc_command_encode_reply_payload_va which is same as
6520 normal command_encode_payload_va except command status type
6521 is provided as extra argument.
6523 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6525 * Added ~./silc directory handling. The directory includes the
6526 public and private keys for the client.
6528 Added silc_client_check_silc_dir, silc_client_create_identifier
6529 and silc_client_load_keys.
6531 * Implemented SILC protocol compliant public key. Added public
6532 and private key saving to and loading from files.
6534 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6535 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6536 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6537 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6538 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6540 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6541 silc_pkcs_load_[public/private]_key.
6543 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Added silc_server_get_route (route.[ch]) to get connection
6546 data for the fastest route for given ID.
6548 * Implemented INVITE command on client and server. The command
6549 were re-defined in the SILC Protocol Specification and the
6550 implementation now complies with the specification.
6552 * Implemented PING command on client and server.
6554 * Implemented NAMES command on client and server. The server side
6555 supports currently only normal server not router server yet.

6560 * Implemented LEAVE command on client and server.
6562 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6563 again. This change was made to the protocol as well. Server
6564 should not violate the protocol specification anymore.
6566 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6569 was tested. SOCKS4 was not but should work anyway.
