1 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Cancel protocol and NULL sock->protocol if timeout
4 occurred during protocol. Affected file silcd/server.c.
6 * Cancel protocol timeouts always before calling the final
7 callback, to assure that after final callback is called
8 no other state will be called for the protocol anymore.
9 Affected file silcd/protocol.c.
11 * Print error log if incoming connection configuration could
12 not be found. Affected file silcd/server.c.
14 * Fixed JOIN command to correctly save the founder mode
15 to the client on normal SILC server, when the channel
16 was created by the router. Affected file silcd/command.c.
18 * Fixed LIST command (hopefully) to send correct reply
19 packets. Affected file silcd/command.c.
21 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
23 * The silc_packet_receive_process now returns FALSE if the
24 read data was invalid packet, and TRUE if it was ok.
26 The server now checks that if unauthenticated connection
27 sends data and its processing fails the server will close
28 the connection since it could be a malicious flooder.
30 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
32 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
34 * Make sure the warning about error opening a log file is
35 printed only once and not everytime it fails (produces
36 too much useless log). Affected file lib/silcutil/silclog.c.
38 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
40 * Made the silc_server_daemonise() function more readable.
41 Affected file silcd/server.c.
43 * Pid file is now optional, the user may comment it out from
44 the config file. Removed define SILC_SERVER_PID_FILE, we
45 don't need a default any longer. Affected file
46 configure.in.pre, lib/Makefile.am.pre.
48 * Make some use of the pid file. The server now dies at startup
49 if it detects a valid pid file on his path. The server would
50 die anyway in this circumstance, because of the bind() failure.
51 Affected file silcd/silcd.c.
53 * No longer compiling lib/dotconf.
55 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
57 * Fixed JOIN command parsing not to crash. Affected file
58 lib/silcclient/command.c.
60 * Fied the NICK_CHANGE notify to add the new client entry
61 even it is resolved. This removes an <[unknown]> nick
62 thingy bug in the client. Affected file is
63 lib/silcclient/client_notify.c.
65 * Do not try to allocate 0 bytes (efence does not like it)
66 in lib/silccore/silccomand.c when encoding payload.
68 * Do not take IRCNICK as nickname in Irssi SILC client since
69 it is not possible to set nickname before hand connecting
70 the server (TODO has an entry about adding auto-nicking
73 * Changed the silc_server_command_pending to check whether
74 there already exists an pending entry with the specified
75 command, command identifier and pending callback. This is
76 to fix IDENTIFY and WHOIS related crashes that may register
77 multiple pending commands with same identifier. Affected
80 * Fixed the server to reconnect to the router even if it
81 was already reconnecting and EOF was received. This to
82 fix a possibility that the server wouldn't ever try to
83 auto-reconnect to the router. Affected file silcd/server.c.
85 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
87 * Fixed the server's password authentication to use the
88 length of the locally saved password, and not the one
89 sent in the packet. Affected file silcd/protocol.c.
91 * Fixed same password authentication problem in the
92 Authentication Payload handling routines in
93 lib/silccore/silcauth.c.
95 * Yet another password authentication problem fixed with
96 channel password handling in silcd/command.c.
98 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
100 * If first character of string in silc_parse_userfqdn is '@'
101 then do not parse it. Affected file is
102 lib/silcutil/silcutil.c.
104 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
106 * Fixed minor bug in IDENTIFY command reply sending, which
107 caused various weird problems during JOIN when it was
108 resolving names for users. Affected file silcd/command.c.
110 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
112 * Fixed the IDENTIFY command reply sending to chech better valid
113 clients. It was possible to send incomplete list of replies.
114 Affected file silcd/command.c.
116 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
118 * Added silc_client_command[s]_[un]register functions now to
119 dynamically register the commands in client library. Removed
120 the static table of commands. This allows the client library
121 to call commands without causing the application to know about
122 what commands library has called.
124 Removed the INFO command reply kludge to detect when the command
125 was called by library. Now library use its own command reply
126 function for INFO command.
128 Added function silc_client_command_call to call a command.
129 Application can use it to call command, not access the structure
132 Now all commands that are sent by the client library (not
133 explicitly sent by application) use own command reply functions.
135 Affected files around lib/silcclient/ and in
136 irssi/src/silc/core/.
138 * Fixed the WHOIS command reply sending to chech better valid
139 clients. It was possible to send incomplete list of replies.
141 Fixed the WHOIS and IDENTIFY to send the request to router
142 if normal server did not do it and did not find any results.
144 Affected file silcd/command.c.
146 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
148 * Moved the internal data from SilcClient context into its
149 own file, not accesible to application. Affected files
150 lib/silcclient/client.h and lib/silcclient/client_internal.h,
151 and other files in client library.
153 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
155 * Added doc/examples installation target in Makefile.am.pre.
158 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
160 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
161 commands the found client entry will be removed from the
162 cache, after notifying application about the error. Affected
163 file lib/silcclient/command_reply.c.
165 * Changed the /MSG to check for exact nickname user gave, and
166 not let `nick' match `nick@host' if it is only one found. Now,
167 user must type the exact nickname (like nick@host2) even if
168 there are no more than one same nicks found. This is to avoid
169 a possibility of sending nickname to wrong nickname since
170 `nick' could match `nick@host'. Affected file is
171 irssi/src/core/silc-servers.c.
173 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
175 * Do not print "you are now server operator" or similar when
176 giving /away command. Affected files are
177 irssi/src/silc/core/client_ops.c, silc-servers.h.
179 * Made the silc_server_command_pending_error_check to send
180 the same command reply payload it received back to the
181 original sender of the command. This way all arguments
182 that was received by the server will be received by the
183 client too. Affected file silcd/command.c.
185 * Added the silc_idcache_add to return the created cache entry
186 to a pointer. Affected file lib/silccore/silcidcache.[ch].
188 * Add global clients to expire if they are not on any channel.
189 This is because normal server will never know if they signoff
190 if they are not on any channel. The cache expiry will take
191 case of these entries. This is done by normal servers only.
192 The affected files are silcd/command_reply.c,
193 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
195 * If server receives invalid ID notification for WHOIS or
196 IDENTIFY and the ID exists in the lists, it is removed.
197 Affected file silcd/command_reply.c.
199 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
200 in client then client entry that it matches is searched and
201 the nickname is printed on the screen for user. Affected
202 file irssi/src/silc/core/client_ops.c.
204 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
206 * Use cache entry expire time in the LIST command reply to
207 purge old entries from the cache after the LIST command
208 reply has been received. This way we don't have non-existent
209 entries in the cache for too long. Affected file is
210 silcd/command_reply.c.
212 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
214 * If we are normal server, and we've not resolved client info
215 in WHOIS or IDENTIFY from router, and it is global client,
216 we'll check whether it is on some channel. If it is not
217 then we cannot be sure about its validity and will resolve it
218 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
219 file silcd/command.c.
221 * Search channel by name (if possible) rather than by ID
222 in IDENTIFY command's command reply. Affected file is
223 silcd/command_reply.c.
225 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
227 * Distribute to the channel passphrase in CMODE_CHANGE notify.
228 Updated specs and implemented it. Affected file silcd/command.c,
229 silcd/packet_send.c and silcd/packet_receive.c.
231 * Implemented the <founder auth> payload handling in the JOIN
232 command. If provided all conditions for channel joining
233 except requirement to provide correct passphrase can be
234 overrided by the channel founder. Updated the protocol specs.
235 Affected file silcd/command.c.
237 Added support for founder auth in JOIN command in client
238 library. Fixed the parsing of the JOIN command now to support
239 all options as they should be. The affected file is
240 lib/silcclient/command.c.
242 * Optimized the WHOIS and IDENTIFY commands to send the request
243 to router only if it includes nicknames or other names. If
244 they include only IDs then check the local cache first before
245 routing. Affected file is silcd/command.c.
247 * Added channels topic announcements. Affected file is
248 silcd/packet_receive.c and silcd/server.c.
250 * Fixed the silc_server_send_notify_topic_set to really destine
251 the packet to channel. Affected file silcd/packet_send.c.
253 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
254 library. Affected file lib/silcclient/client_notify.c.
256 * Added UMODE announcements. Affected file silcd/server.c.
258 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
260 * Memory leak fixes in:
262 lib/silcutil/silcsockconn.c
263 lib/silcske/silcske.c
266 lib/silccrypt/silcpkcs.c
267 lib/silccore/silccommand.c
268 lib/silccore/silcidcache.c
273 * ROBOdoc documented the lib/silcske/groups.h file and a
274 bit changed the interface for better.
276 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
278 * Update the client entry context in the ID cache after
279 nick change. Affected file lib/silcclient/command.c.
280 Fixes the CUMODE command when regaining founder privileges,
281 and a little WHOIS problem.
283 * Fixed silc_net_gethostbyname to correctly call the
284 inet_ntop. Affected file lib/silcutil/silcnet.c.
286 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
288 * Added IPv6 support checking to the configure.in.pre, added
289 also --enable-ipv6 option to override the check. Affected
290 file configure.in.pre.
292 * The silc_thread_create now calls the start function
293 directly if threads support is not compiled in. Removes
294 ugly #ifdef's from generic code. Affected files are
295 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
297 * Added silc_net_gethostby[name/addr]_async to asynchronously
298 resolve. Affected files are lib/silcutil/silcnet.[ch].
300 * Added support for rendering IPv6 based server, client and
301 channel IDs. Affected file lib/silcutil/silcutil.c.
303 * Added support for creating IPv6 based server IDs. Affected
304 file is silcd/serverid.c.
306 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'

309 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
310 routines. Added silc_net_is_ip[4/6]. Affected file is
311 lib/silcutil/unix/silcunixnet.c. All routines that take
312 address as argument now supports both IPv4 and IPv6 addresses.
314 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
316 * Fixed LIST command reply sending in server. Affected file
319 * Server now sends the kicker's client ID in the KICK notify
320 to the kicked client. Affected file silcd/command.c.
322 * The client library now parses the kickers client ID and
323 UI displays it. Affected files lib/silcclient/client_notify.c
324 and irssi/src/silc/core/silc-channels.c, module-formats.c.
326 * Made all payload parsing function prototypes consistent.
327 They all take now const unsigned char * and uint32 pair as
328 the payload data instead of SilcBuffer. Changes all around
329 the source tree. Other unsigned char* -> const unsigned char*
330 changes around the tree as well.
332 * Optimized SFTP client and server packet sending not to
333 allocate new buffer for each packet but to recycle the
334 first allocated buffer. Affected files are
335 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
337 * Optimized the SFTP client to use SilcList instead of
338 SilcDList for requests, because it is faster. Affected file
339 is lib/silcsftp/sftp_client.c.
341 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
342 into lib/silccore/silcid.[ch].
344 Renamed silcpayload.[ch] into silcargument.[ch].
346 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
348 * If client entry is deleted with active key agreement
349 session, abort the session.
351 The silc_client_abort_key_agreement now calls the completion
352 callback with new SILC_KEY_AGREEMENT_ABORTED status.
354 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
357 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
359 * Don't use __restrict in older GCC's. Affected file is
360 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
362 * silc_net_localhost now attempts to reverse lookup the
363 IP/hostname. Affected file lib/silcutil/silcnet.c.
365 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
366 command. It can be used to gain founder privileges at
367 the same time when joining the channel.
369 Defined that the SILC_NOTIFY_TYPE_KICKED send the
370 kicker's client ID as well. Updated protocol specs.
372 Defined that the server must send SILC_COMMAND_IDENTIFY
373 command reply with error status to client who sent
374 private message with invalid client ID.
376 Updated the protocol specification.
378 * Added silc_server_send_command_reply to send any
379 command reply. Affected file silcd/packet_send.[ch].
381 * Added silc_id_payload_encode_data to encode ID payload
382 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
384 * The server now send IDENTIFY command reply with error
385 status if client ID in private message is invalid. Affected
386 file silcd/packet_receive.c.
388 * Save the server key file with server's IP address in
389 the filename instead of hostname. The affected file is
390 irssi/src/silc/core/client_ops.c.
392 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
394 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
397 * Added libtool support for compiling shared objects in
398 lib/silcsim. Affected file configure.in.pre and
399 lib/silcsim/Makefile.am. Original patch by cras.
401 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>

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

436 to run server on foreground. A patch by debolaz.
437 Affected files silcd/server.c, silcd/silcd.c.
439 * Fixed MOTD to return the MOTD file server name. Affected
440 file silcd/command.c.
442 * Added INFO command reply handling to the Irssi SILC Client.
443 Affected file irssi/src/silc/core/client_ops.c.
445 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
447 * Fixed the silc_idcache_list_* routines to really support
448 the dynamic list. Fixes a crash. Affected file is
449 lib/silccore/silcidcache.c.
451 * Fixed the LIST command reply to really call LIST command's
452 pending callbacks. Affected file silcd/command_reply.c.
454 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
456 * Update conn->local_entry->nickname after giving NICK
457 command. Affected file lib/silcclient/command.c.
459 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
461 * Added the [pid] option to the silcd configuration file
463 Affected files: serverconfig.[ch] and silcd.c
465 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
467 * Save fingerprint in WHOIS command reply in server.
468 Affected file silcd/command_reply.c.
470 * Fixed NICK commands pending callback registration.
471 Affected file lib/silcclient/command.c.
473 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
475 * Use ++server->cmd_ident when sending commands in server,
476 instead of random number. Affected file silcd/command.c.
478 * Fixed GETKEY command reply to call actually GETKEY pending
479 command callbacks. Affected file silcd/command_reply.c.
481 * A bit stricter check for nicknames. Check for same nickname
482 in NICK command also. Affected file silcd/command.c.
484 * Do not call INFO command everytime client ID changes, only
485 during first connecting. Affected file lib/silcclient/client.c.
487 * Set the new nickname only after successful command reply for
488 NICK command is returned by server. Affected file
489 lib/silcclient/command.c.
491 * Remove nicknames from nicklist during server_signoff notify.
492 Should fix /NAMES bit more. The affected file is
493 irssi/src/silc/core/silc-channels.c.
495 * Added `fingerprint' field to the SilcIDListData in the
496 silcd/idlist.h to hold the fingerprint of the client's
499 Send the fingerprint of the client's public key in WHOIS
502 Affected files silcd/command.c, and silcd/idlist.[ch].
504 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
505 create fingerprint from given data.
507 * Show the fingerprint of the client's public key in WHOIS.
508 Affected files irssi/src/module-formats.[ch] and
509 irssi/src/silc/core/client_ops.c.
511 * Format the multiple same nicknames also during JOIN and
512 NICK_CHANGE notifys. Affected file is
513 lib/silcclient/client_notify.c.
515 * Do not print error on screen for invalid private message
516 payload since it can come if someone is sending private
517 messages with wrong key. Affected file
518 lib/silccore/silcprivate.c.
520 * Fixed multiple concurrent /PING crash. Affected file
521 lib/silcclient/command.c.
523 * Changed the wrong ID encoding. All IP addresses must be
524 in MSB first order in encoded format. They were encoded
525 wrong and was in LSB format. Affected files are
526 silcd/serverid.c, lib/silcutil/silcutil.c.
528 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
530 * Call the `connect' client operation through the scheduler
531 in case of error. Affected file lib/silcclient/client.c.
533 * Call the `failure' client operation even if the error
534 occurred locally during a protocol. Affected file is
535 lib/silcclient/protocol.c.
537 * Added support of sending LIST command to router from normal
538 server. This way normal server can get list of all channels
539 in the network too. Fixed the channel list sending in the
540 server too. Affected files are silcd/command.c, and
541 silcd/command_reply.[ch].
543 * Added silc_server_update_channels_by_server and
544 silc_server_remove_channels_by_server. They are used during
545 disconnection of primary router and in backup router protocol.
546 Affected file silcd/server_util.[ch], silcd/server.c and
547 silcd/server_backup.c.
549 * Fixed channel adding to global list in IDENTIFY command
550 reply in server. Affected file silcd/command_reply.c.
552 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
554 * If the incoming packet type is REKEY or REKEY_DONE process
555 that packet always synchronously. Fixes yet another MAC
556 failed error on slow (dialup) connections. Affected file
557 lib/silcclient/client.c and silcd/server.c.
559 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
561 * Call check_version SKE callback for initiator too. Affected
562 file lib/silcske/silcske.c.
564 * Implemented fix for security hole found in the SKE that was
565 fixed in the specification few days back; the initiator's
566 public key is now added to the HASH value computation.
567 Added backwards support for the old way of doing it too, for
568 old clients and old servers. Affected file is
569 lib/silcske/silcske.c.
571 * Enabled mutual authentication by default in SKE. If initiator
572 is not providing mutual authentication the responder will
573 force it. This will provide the proof of posession of the
574 private key for responder. The affected files are
575 lib/silcclient/protocol.c and silcd/protocol.c.
577 * Do not cache anymore the server's public key during SKE.
578 We do mutual authentication so the proof of posession of
579 private key is done, and if the server is authenticated in
580 conn auth protocol with public key we must have the public
581 key already. Affected file silcd/protocol.c.
583 * Added new global debug variable: silc_debug_hexdump. If
584 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
585 file lib/silcutil/silclog.[ch].
587 * Fixed compilation warning due to char * -> const char *.
588 Affected files lib/silcutil/silcnet.h, and
589 lib/silccore/silcauth.[ch].
591 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
593 * Fixed CMODE command when new channel key was created. If
594 the creation failed the old key was removed. Next time giving
595 same command would crash the server since the old key was
596 freed already. Affected file silcd/command.c.
598 * Fixed the silc_server_announce_get_channels to not crash
599 on reconnect. Affected file silcd/server.c.
601 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
603 * Added silc_log_set_debug_string function to set a regex
604 string to match for debug output. Only the function names,
605 or filenames matching the given debug string is actually
606 printed. This way it is possible to filter out those debug
607 strings that user is not interested in.
609 Fixed a bug in silc_string_regexify.
611 Affected files lib/silcutil/silclog.[ch], and
612 lib/silcutil/unix/silcunixutil.c.
614 * Changed the -d options in both server and Irssi SILC client
615 to take the debug string as argument. Affected files
616 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
618 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
620 * Added silc_hash_babbleprint to create a Bubble Babble
621 Encoded fingerprint. The encoding is developed by Antti
622 Huima (draft-huima-babble-01.txt), and it creates human
623 readable strings out of binary data. Affected file
624 lib/silccrypt/silchash.[ch].
626 * Print the babble print now in addition of fingerprint as well
627 in Irssi SILC client. Affected files are
628 irssi/src/fe-common/silc/module-formats.[ch],
629 irssi/src/fe-common/silc/core/client_ops.c.
631 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
633 * Fixed a security problem found in SKE. The initiator's
634 public key too is now added to the HASH hash value creation
635 which is signed by the responder to create the SIGN value.
636 This will prevent anyone in the middle to lie to the responder
637 about the initiator's public key. If this is done now, the
638 man in the middle will get caught. Updated the protocol
641 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
643 * Better installation directory handling. Configure module
644 paths and other paths automatically to example_silc* files
645 in doc/. A patch by toma.
647 * Fixed compiler warning from MPI library, and from SILC RNG.
650 * Added SILC_SERVER_PID_FILE to define the pid file for server.
651 It can be configured with ./configure. A patch by toma.
653 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
655 * Find correct make to use in prepare-clean. A patch by
656 toma. Affected file prepare-clean.
658 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
660 * Added irssi variables use_auto_addr, auto_bind_ip,
661 auto_bind_port and auto_public_ip.
663 * Changed the interface for silc_client_send_key_agreement
664 in lib/silcclient/silcapi.h
668 irssi/src/silc/core/silc-core.c
670 lib/silcclient/silcapi.h
671 irssi/src/silc/core/silc-channels.c
672 lib/silcclient/client_keyagr.c
675 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
677 * Added silc_pkcs_public_key_compare to compare two
678 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
680 * Check that the client who set the founder mode on the
681 channel is the same client that is giving the founder
682 mode to itself. It is done by comparing the saved public
683 key (it is saved even in the authentication is passphrase).
684 Affected file silcd/command.c.
686 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
688 * Do not process packet for disconnected socket connection.
689 Affected file lib/silccore/silcpacket.c.
691 * Process the DISCONNECT packet through scheduler in the
692 client library. Affected file lib/silcclient/client.c.
694 * Fixed the silc_client_packet_parse to not to increase
695 the packet sequence number if the conn->sock and the
696 current socket connection is not same. This can happen
697 for example during key agreement when the conn includes
698 multiple socket connections (listeners). Affected file
699 lib/silcclient/client.c.
701 * The sender of the file transfer request now provides also
702 the pointer (listener) for the key exchange protocol. If
703 the listener cannot be created then it sends empty key
704 agreement and lets the receiver provide the listener.
706 Added `local_ip' and `local_port' arguments to the
707 silc_client_file_send. If they are provided they are used,
708 if not then it will attempt to find local IP address, if
709 not found or bind fails then the remote client will provide
712 Affected files are lib/silcclient/client_ftp.c and
713 lib/silcclient/silcapi.h.
715 * Extended the FILE SEND command to support defining the
716 local IP and port for key exchange listener. They are
717 optional. Affected file irssi/src/silc/core/silc-servers.c.
719 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
721 * Defined to WHOIS command reply the sending of fingerprint
722 of the client's public key (if the proof of posession of the
723 corresponding private key is verified by the server).
724 Updated to the protocol specification.
726 * Added support of receiving the client's public key's
727 fingerprint in command reply in client library. Affected
728 file is lib/silcclient/command_reply.c, and
729 lib/silcclient/idlist.[ch].
731 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
733 * Do not send over 128 chars long nickname to the server
734 in NICK command. Affected file lib/silcclient/command.c.

737 in JOIN command. Affected file lib/silcclient/command.c.
739 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
741 * Assure that silc_server_close_connection cannot be called
742 twice for same socket context. Affected file is
745 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
747 * Send error message to application if opening file for
748 writing during file transfer fails. Affected file is
749 lib/silcclient/client_ftp.c.
751 Remove all file transfer sessions for a client that we're
752 removing from ID cache.
754 Affected file is lib/silcclient/client_ftp.c.
756 * Fixed silc_net_addr2bin to return correct address. Affected
757 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
759 * Fixed file transfer session removing on signoff notify.
760 Affected file irssi/src/silc/core/silc-servers.c.

773 to indicate if the server entry is disabled. Affected file
774 silcd/idlist.h, silcd/command[_reply].c.
776 * SILC server adds now /var/run/silcd.pid everytime it is
777 started. Affected file silcd/silcd.c.
779 * Added silc_server_packet_send_clients to send a packet to
780 the provided table of client entries. Affected file
781 silcd/packet_send.[ch].

784 client library. Affected file lib/silcclient/client_prvmsg.c.
786 * Do not actually remove the client directly from ID cache
787 during SERVER_SIGNOFF, but invalidate it. This way we
788 preserve the WHOWAS info for the client. Affected file
791 * Fixed SERVER_SIGNOFF notify handling in the server. The
792 server is now able to process incoming SERVER_SIGNOFF notify
793 for a server that it doesn't even know about. It will remove
794 the clients provided in the notify. Affected file
795 silcd/packet_receive.c.
797 * Check for partial packet in data queue after every packet that
798 was found from the queue. Return and wait for more data if
799 there is partial data in queue. Affected file is
800 lib/silccore/silcpacket.c.
802 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

810 * Check that newsize in silc_buffer_realloc is larger than
811 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
813 * Added better monitor of file transfers. It now monitors
814 key agreement protocol during the file transfer too. Added
815 error reporting too. Affected files
816 irssi/src/silc/core/silc-servers.c,
817 irssi/src/fe-common/silc/module-formats.[ch].
819 * Wrote a help file for FILE command.
821 * Added silc_rng_global_get_byte_fast to get not-so-secure
822 random data as fast as possible. Random data is read from
823 /dev/urandom if available and from the SILC RNG if not
824 available. It is used in padding generation. Affected file
825 lib/silccrypt/silcrng.[ch].
827 * All packets in client library are now processed synchronously.
828 Optimized packet processing a lot. Affected file
829 lib/silcclient/client.c.
831 * All server connection packets are processing synchronously
832 now in server, to optimize packet processing. Affected file
835 * Include files are installed now only in Toolkit distribution
836 if make install is given. Affected files: all Makefile.am's.
838 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
840 * Assure that silc_client_notify_by_server_resolve does not
841 resolve the client information multiple times. If it cannot
842 be found by the first it cannot be found at all. Affected
843 file lib/silcclient/client_notify.c.
845 * Fixed WHOWAS command reply calling. Affected file
846 lib/silcclient/command_reply.c.
848 * Removed all references to silc_idlist_get_client from the
849 Irssi SILC client since that call is internal call used by
850 the library. The Irssi SILC client will use now client
851 retrieval functions found in silcapi.h.
853 * Fixed a bug in resolving nickname info before sending
854 private message. It used freed memory. Affected file
855 irssi/src/silc/core/silc-servers.c.
857 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
859 * Assure my_channels statistics cannot go negative in server.
860 Affected files silcd/server.c, silcd/server_util.c.

876 * Added silc_net_localip to return local host's IP address.
877 Affected file lib/silcutil/silcnet.[ch].
879 * If key exchange or rekey protocol is active for a connection
880 parse all packets syncronously since there might be packets
881 in packet queue that we are not able to process without first
882 processing packets before them. Affected file silcd/server,
883 lib/silcclient/client.c.
885 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
886 whether library should continue processing the packet.
887 Affected file lib/silccore/silcpacket.h.
889 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
890 SilcSFTPMonitorData to SFTP server to monitor various

918 lib/silcutil/silcutil.[ch].
920 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
922 * Resolve the client info when received private message or
923 channel message for a client which nickname we don't know.
924 Affected files lib/silcclient/client_prvmsg.c and
925 lib/silcclient/client_channel.c.
927 * Do not crash in /KEY if client is not connected. Affected
928 file irssi/src/silc/core/silc-channels.c.
930 * Added SilcClientStatus field to the SilcClientEntry in the
931 lib/silcclient/idlist.h.
933 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
934 is incomplete and is being resolved, it won't be resolved
937 Make sure also that USERS command reply does not resolve
938 twice information. Affected file is
939 lib/silcclient/command_reply.c.
941 Make sure that silc_client_get_clients_by_list does not
942 resolve twice same information.
944 * Check for valid client->id in the silc_server_free_client_data.
945 Affected file silcd/server.c.
947 * Fixed /GETKEY nick@server not to crash if the server entry
948 is not found. Affected file lib/silcclient/command.c.
950 * Fixed the silc_server_check_cmode_rights to check the
951 requested modes correctly. Affected file silcd/command.c.

955 * Better checks for non-printable chars in nick added.
956 Affected file silcd/command.c.
958 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
960 * Call the silc_server_udpate_servers_by_server in the
961 primary router that comes back online in the backup resuming
962 protocol. Otherwise it routes packets wrong. Affected file
963 silcd/server_util.[ch], silcd/server_backup.c.
965 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
967 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
968 lib/silcutil/silcbuffmt.[ch].
970 * Redefined the SILC packet header to include the padding
971 length. Affected file lib/silccore/silcpacket.[ch].
973 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
974 length for maximum padding up to 128 bytes). Affected
975 file lib/silccore/silcpacket.h.
977 * Removed all backwards support for old 0.5.x MAC thingies.
978 The SILC packet header change makes it impossible to be
979 backwards compatible.
981 * Send the ENDING packet with timeout in the backup resuming
982 protocol. This is to assure that all routers has connected
983 to the primary router. Affected file silcd/server_backup.c.
985 * Changed the RNG to take the first IV from random data. It
986 used to take it from zero actually. Changed the RNG also
987 to use /dev/urandom during session. /dev/random is used
988 in initialization. Affected file lib/silccrypt/silcrng.[ch].
990 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
992 * Changed the SILC packet header to have the first two bytes
993 (the packet length) encrypted. Affected files aroung the
994 code tree, lib/silccore/silcpacket.[ch]. Removed the
995 SilcPacketCheckDecrypt callback. It is not needed anymore
996 since the silc_packet_receive_process will determine now
997 whether the packet is normal or special.
999 * Implemented the unidirectional MAC keys. Affected files
1000 lib/silcske/silcske.c, silcd/protocol.c and
1001 lib/silcclient/protocol.c.
1003 * Implemented the packet sequence number to the MAC computation.

1008 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1010 * Allow backup router to announce servers. All servers
1011 announced by backup router are added to the global list
1012 automatically. Update hte server's socket to our primary
1013 router also when backup router announces a server.
1014 Affected file silcd/packet_receive.c.
1016 * Do not update the client->router in the function
1017 silc_server_udpate_clients_by_server if the client is on
1018 global list. We might fail to find any specific server
1019 for locally connected clients and local cell clients. They
1020 should still use the `from' and not `to' as client->router.
1021 This fixes backup router resuming protocol. Affected file
1022 silcd/server_util.c.
1024 * Decrease channel statistics count only if the channel
1025 deletion worked. Affected files are silcd/server.c and
1026 silcd/server_util.c.
1028 * Added silc_server_update_servers_by_server to update origin
1029 of all server entries. Used during backup router protocol.
1030 Affected files silcd/server_util.[ch], silcd/server.c. and
1031 silcd/backup_router.c.
1033 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1034 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1035 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1036 lib/silccrypt/silchmac.c.
1038 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1040 * Assure that router cannot reroute the same channel message
1041 to the sender. Affected file silcd/packet_receive.c.
1043 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1045 * Made better checks that the channel message is not sent
1046 to the router it came from. Affected file is
1047 silcd/packet_send.c. Fixed memory leak too.
1049 * Announce informations for incoming router connection, but
1050 only after checking if it is replaced by backup router.
1051 Affected file silcd/packet_receive.c.
1053 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1055 * Fixed the backup resuming protocol to work in multiple
1056 router environment. Affected file silcd/server_backup.c.
1058 * Route packet only to one router in the function
1059 silc_server_packet_send_to_channel. Affected file is
1060 silcd/packet_send.c.
1062 * Fixed silc_server_send_notify_dest to set the broadcast
1063 flag. Fixed the silc_server_send_notify_topic to actually
1064 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1065 Affected file silcd/packet_send.c.
1067 * Changed the SFTP Filesystem interface. Changed the
1068 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1069 the filesystem operation function. The SilcSFTPFilesystem
1070 is now a context that is allocated by all filesystem allocation
1071 functions and it already includes the operations structure
1072 and filesystem specific context. It is given as argument
1073 now to the silc_sftp_server_start. This made the interface
1074 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1075 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1077 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1079 * Changed the backup router adding and getting interfaces
1080 in the server. The router that will be replaced by the
1081 specified backup router is now sent as argument. Affected
1082 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1085 * Added silc_net_addr2bin_ne to return the binary form of
1086 the IP address in network byte order. Affected files
1087 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1089 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1091 * Check for existing server ID in silc_server_new_server
1092 and in silc_server_connect_to_router_final and remove the
1093 old entry if it exists. Affected file silcd/packet_receive.c,
1096 * Send the channel message always to only one router, either
1097 in upstream or downstream. Affected file is
1098 silcd/packet_send.c.
1100 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1102 * Wrote the definition of the backup resuming protocol to the
1103 protocol specification.
1105 * Removed one redundant channel key generation from normal
1106 server during joining procedure. Removed one redundant
1107 channel key sending from server to router during joining
1108 procedure. Affected file silcd/command.c.
1110 * Made minor bugfixes to the backup router resuming protocol.
1111 Affected file silcd/server_backup.c, server.c.
1113 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1115 * Added --disable-asm configuration option. Affected files
1116 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1119 * Implemented the backup resuming protocol that is used to
1120 resume the primary router position in the cell after the
1121 primary router comes back online. Affected files
1122 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1123 and silcd/server_util.[ch].
1125 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1127 * Sleep two (2) seconds after sending QUIT command to server.
1128 Affected file lib/silcclient/command.c.
1130 * Assure that if outgoing data buffer is pending do not force
1131 send any data. Affected file silcd/packet_send.c.
1133 * Assure that if outgoing data buffer is pending do not force
1134 send any data. Affected file lib/silcclient/client.c.
1136 * Implemented the backup router support when the primary router
1137 goes down. The servers and routers can now use the backup
1138 router as new primary router without loosing connectivity.
1140 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1143 in the server to indicate disabled entry. All data read
1144 from the connection will be ignored and no data is sent
1145 for entry that is disabled. Affected files are
1146 silcd/idlist.h, silcd/server.c.
1148 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1150 * Created SFTP client and server test programs in the
1151 lib/silcsftp/tests directory.
1153 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1155 * Implemented memory filesystem (virtual filesystem) for
1156 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1159 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1161 * Implemented the SFTP (SSH File Transfer Protocol) to the
1162 lib/silcsftp. It includes SFTP client and SFTP server
1165 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Moved lib/silccore/silcprotocol.[ch] to the
1168 lib/silcutil library.
1170 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1171 take variable argument list pointer as argument. Affected
1172 file lib/silcutil/silcbuffmt.[ch].
1174 * Added silc_buffer_set function that is used to set data
1175 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1176 Affected file lib/silcutil/silcbuffer.h.
1178 * Changed various routines in the core library to use the new
1179 silc_buffer_set instead of allocating new buffer only for
1182 * Added 64-bit value formatting and unformatting support to the
1183 silc_buffer_[un]format routines. Affected file is
1184 lib/silcutil/silcbuffmt.[ch].
1186 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1187 to includes/bitmove.h.
1189 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1191 * Fixed channel user mode saving in client library. Affected
1192 file lib/silcclient/command[_reply].c.
1194 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1196 * Defined the file transfer to the SILC Protocol. Added
1197 new packet type SILC_PACKET_FTP and defined File Transfer
1198 Payload. The mandatory file transfer protocol is SFTP
1199 (SSH File Transfer Protocol). Affected file in addition
1200 of the internet draft is lib/silccore/silcpacket.h.
1202 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1203 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1204 is used as part of backup router protocol when the primary
1205 router of the cell is back online and wishes to resume
1206 the position as primary router.
1208 * Redefined the MAC generation keys in the protocol. The
1209 same key is not used anymore in both direction. Both
1210 direction will now use different keys for sending and
1211 receiving. This fixes a potential security flaw. This
1212 change causes incompatibilities in the protocol.
1214 * Redefined also the MAC computation from the packet.
1215 An packet sequence number is now added to the MAC
1216 computation. This prevents possible replay attacks against
1217 the protocol. This change too causes incompatibilities
1220 Added `sequence' field to the SilcPacketContext to hold
1221 the current sequence number for the packet.
1223 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1225 * Added `created' field to the SilcIDListData in the file
1226 silcd/idlist.h to indicate the time when the entry was
1229 * Added `created' field to the SilcChannelEntry too. Affected
1230 file silcd/idlist.h.
1232 * Added `creation_time' aguments to all the announcement functions
1233 in the server. If it is provided then only the entries that
1234 was created after the provided time frame are actually
1235 announced. Affected file silcd/server.[ch].
1237 * The protocol says that the Channel ID's IP address must be
1238 based on the router's IP address. Added check for this in
1239 the silc_server_new_channel when processing incoming New Channel
1240 Payload. Affected file silcd/packet_receive.c.
1242 * Print out the correct version with --version in SILC client.
1243 Affected file irssi/src/silc/core/silc-core.c.
1245 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1247 * Fixed WHOWAS command to check for completnes of the client
1248 entry always, not just when the command is coming from client.
1249 Affected file silcd/command.c.
1251 * Added new function silc_server_packet_queue_purge to purge the
1252 outgoing data queue to the network. After the function returns
1253 it is guaranteed that the outgoing packet queue is empty.
1254 Affected file silcd/packet_send.[ch].
1256 * Purge the outgoing packet queue in the rekey protocol's final
1257 callback to assure that all rekey packets go to the network
1258 before quitting the protocol. Affected file silcd/server.c.
1260 * Added silc_client_packet_queue_parse as similar function as
1261 in server to the client library. The affected file is
1262 lib/silcclient/client.c.
1264 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Splitted silcd/server.c and created silcd/server_util.[ch]
1267 for utility functions.
1269 * Added new socket flag SILC_SF_DISABLED to indicate that the
1270 connection is open but nothing can be sent to or received from
1271 the connection. Affected file lib/silcutil/silsockconn.[ch].
1272 The checking for disabled socket is checked in the low level
1273 silc_socket_write and silc_socket_read functions.
1275 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Allow only nicknames and channel names that fits into the
1278 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1280 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1282 * When processing JOIN command reply in server check that if
1283 the channel exists in our global list we'll move it the local
1284 list. Affected file silcd/command_reply.c.
1286 * Fixed the check whether client is joined on the channel already
1287 in JOIN command. Affected file lib/silcclient/command.c.
1289 * Fixed the JOIN command reply to check whether the channel
1290 already exists. Affected file lib/silcclient/command_reply.c.
1292 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1294 * Added silc_ske_status_string to map the SKE error numbers
1295 to readable strings. The affected files are
1296 lib/silcske/silcske[_status].[ch].
1298 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1300 * Do not show the private channels on the WHOIS channel list
1301 as it is not allowed by the protocol. The affected file is
1304 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1306 * Assure that the packet length digged from the actual packet
1307 is something sensible in the silc_packet_decrypt_rest_special
1308 in lib/silccrypt/silcpacket.c.
1310 * Free and NULL the allocated pointer in silc_hmac_alloc if
1311 the HMAC allocation fails. The affected file is
1312 lib/silccrypt/silchmac.c.
1314 * Print the selected security properties to the log files in
1315 the server. Affected file silcd/protocol.c.
1317 * Add SKE's reference counter even if calling the completion
1318 callback manually. Otherwise it goes negative, although it
1319 does not cause any problems. The affected file is
1320 lib/silcske/silcske.c.
1322 * Remove the client entry with short timeout after giving the
1323 KILL command. Affected file lib/silcclient/command.c.
1325 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1326 case all found clients are already disconnected (WHOWAS would
1327 found them) in the server. Affected file silcd/command.c.
1329 * Update the last_receive (time of last data received) to be
1330 updated only when received private or channel message so that
1331 the idle time showed in WHOIS makes more sense.
1333 * Added boolean field `valid' in to the SilcClientEntry in the
1334 client library to indicate whether the entry is valid or not.
1335 This fixes the nickname change bug on channel when changing
1336 the nickname to be same than the old (like nick to Nick) the
1337 nickname formatter doesn't set the new nick anymore to Nick@host.
1338 Affected file lib/silcclient/idlist.[ch].
1340 * Now actually fixed the nickname changing on disconnection.
1341 Added new function silc_change_nick to the Irssi SILC Client.
1342 Affected file irssi/src/silc/core/client_ops.c,
1343 irssi/src/silc/core/silc-nicklist.[ch].
1345 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1347 * Check that the public key exists in the GETKEY command before
1348 trying to encode it. Affected file silcd/command.c.
1350 * Print some notifications on received public keys with GETKEY
1351 command in the Irssi SILC Client. Affected files are
1352 irssi/src/fe-common/silc/module-formats.[ch],
1353 irssi/src/silc/core/client_ops.c.
1355 * Use IDENTIFY command to resolve the server information in the
1356 GETKEY command instead of INFO command. Affected file
1357 lib/silcclient/command.c.
1359 * All command reply functions in the client library now calls
1360 the pending command reply callbacks even if an error has
1361 occurred. The server has done this a long time and now it was
1362 time to move the client library to this as well. Now all
1363 errors can be delivered back to the pending command reply
1364 callbacks if necessary. Affected files are
1365 lib/silcclient/command[_reply].[ch].
1367 * Change the nickname on disconnection back to the username
1368 because in reconnect the server will enforce it to it anyway.
1369 Affected file irssi/src/silc/core/silc-servers.c.
1371 * Fixed a config file parsing bug in the Irssi SILC client.
1372 Affected file irssi/src/silc/core/clientconfig.c.
1374 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1376 * When printing the channel mode on JOIN, verify that the
1377 channel key and channel's HMAC are valid. Affected file
1378 irssi/src/silc/core/client_ops.c.
1380 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1382 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1383 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1384 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1386 * Removed channel key rekey task deleting from the function
1387 silc_server_save_channel_key. Affected file silcd/server.c.
1388 Added explicit timeout task context instead that is used to
1389 delete the task if we are registering a new task before the
1390 new task has elapsed.
1392 * When channel key rekey occurs the client library now saves
1393 the old channel key for a short period of time (10 seconds) and
1394 is able to use it in case some is still sending channel
1395 messages encrypted with the old key after the rekey. Affected
1396 file lib/silcclient/[idlist.h|client_channel.c].
1398 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1400 * Added check to the silc_server_new_id_real to not accept
1401 new ID if it is the sender's own ID. Affected file is
1402 silcd/packet_receive.c.
1404 * Assure that we do not announce ourself or the one we've
1405 sending our announcements when we're router and are announcing
1406 servers to our primary router. Affected file silcd/server.c.
1408 * Fixed silc_server_command_identify_check_client to assemble
1409 correct WHOIS packet. It send corrupted WHOIS packet and
1410 caused problem with router to router connections. Affected
1411 file silcd/command.c.
1413 Fixed also silc_server_command_whois_check the same way
1414 as for the IDENTIFY command.
1416 * Added new SilcIDListStatus to the server in the SilcIDListData
1417 structure. The status now includes the current status of
1418 the entry (like registered, resolved etc.). Affected file
1419 silcd/idlist.[ch]. Defined a bunch of different status types
1420 as well. This replaced the old boolean registered field as well.
1422 Added resolve_cmd_ident field to the SilcClientEntry structure
1423 too so that if the entry is for example being resolved so
1424 another command may attach to the same pending command reply
1425 without requiring to resolve the same entry again. This concept
1426 should optimize the WHOIS and the IDENTIFY resolving under
1427 heavy load by taking away unnecessary resolving for entries
1428 that are being resolved already.
1430 Added support for adding multiple pending commands for one
1431 command idenfier. Affected file silcd/command[_reply].[ch].
1433 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1434 before deleting the data. Otherwise the hash table will have
1435 freed data in comparison functions. Affected file is
1436 silcd/command_reply.c.
1438 * Fixed silc_idlist_replace_client_id to add the new entry to
1439 the cache with NULL nickname. Otherwise there will be invalid
1440 memory as the nickname after the nickname is freed. Affected
1441 file silcd/packet_receive.c.
1443 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1444 saved into wrong slots because the previous number of entries
1445 was not taken into account. Affected file silcd/idlist.c.
1446 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1448 * If we are router and we receive JOIN notify to a channel that
1449 does not have any users then notified client is marked as the
1450 channel founder, as it is it. The affected file is
1451 silcd/packet_receive.c
1453 * Added to the extended hash table API's table_del_*ext functions
1454 the destructor as argument too, so that the caller can decide
1455 which destructor to use or whether to use destructor at all.
1456 Affected file lib/silcutil/silchashtable.[ch].
1458 * Fixed ID Cache purging. It actually deleted the entries from
1459 the hash table after the data was freed. The hash table ended
1460 up comparing freed memory. The affected file is
1461 lib/silccore/silcidcache.c.
1463 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1465 * Fixed Irssi SILC client's KILL command's HELP syntax.
1467 * The USERS command now resolves the detailed user information
1468 if the userinfo field is missing. Affected file is
1469 lib/silcclient/command_reply.c.
1471 * Do not print error in silc_file_read if the read file does
1472 not exist. Just silently return NULL. Affected file is
1473 lib/silcutil/silcutil.c.
1475 * Fixed the silc_log_output to not wine about NULL filename
1476 and to not create some bogus " " filename. Affected file is
1477 lib/silcutil/silclog.c.
1479 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1481 * Fixed various printing bugs on the user interface in the
1482 Irssi SILC Client. Minor changes that were forgotten from
1485 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1487 * Fixed the configure.in.pre and the compilation and distribution
1488 environment to support the new autoconf 2.52. That version is
1489 now required to compile the CVS trunk.
1491 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1494 to generally parse user@fqdn format strings. Affected file
1495 lib/silcutil/silcutil.c.
1497 * Added nickname_format and nickname_force_format fields to the
1498 SilcClientParams structure. The first one defines the format
1499 for the nicknames that the library will enforce if the receives
1500 multiple same nicknames. The second one is boolean value and
1501 can be used to force the library to always enforce the format
1502 to the nicknames regardles whether there are multiple nicknames
1503 or not. This configurable formatting was employed to flexibly
1504 support accessing multiple nicknames from the user interface.
1505 The userinterface can now set the nicknames to what ever format
1506 they prefer. Affected file lib/silcclient/silcapi.h.
1508 Added function silc_client_nickname_format to the file
1509 lib/silcclient/idlist.c. It performs the nickname formatting.
1511 Added new field `hostname´ to the SilcClientEntry context.
1512 It holds the hostname of the client. Affected file is
1513 lib/silcclient/idlist.h.
1515 * Irssi SILC Client sets the nicknames in nick@hostn format.
1516 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1517 irssi/src/silc/core/silc-core.c.
1519 The WHOIS printing now also shows both the real nickname and
1520 the formatted nickname so that user knows how to access the
1521 user if there are multiple same nicknames cached. Affected
1522 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1523 printing formatting too to take the hostname now as a separate
1524 argument. The Affected file is
1525 irssi/src/fe-common/silc/modules-formats.[ch].
1527 * Changed the silc_client_get_clients_local to accept the formatted
1528 nickname as argument. It accepts the real nickname too but the
1529 formatted nickname can be used to find the true entry from
1530 multiple entries. Affected file lib/silcclient/silcapi.h and
1531 lib/silcclient/idlist.c.
1533 * Added nickname_format_parse field to the SilcClientParams.
1534 It is a callback function provided by the application to parse
1535 the nickname out of the formatted nickname string. The library
1536 calls it to get the nickname from the formatted string. Since
1537 the application generally knows better the format of the nickname
1538 string it parses it instead of the library, even though library
1539 encodes the formatted string. If the callback function is not
1540 provided then the library will use the string as is. The
1541 affected file is lib/silcclient/silcapi.h.
1543 * All the nickname strings passed to the client library in
1544 commands are now expected to be formatted nickname strings.
1545 If the command does not support the formatted nickname string
1546 it will assume that the sent string is the actual nickname.
1547 Affected file lib/silcclient/command.c.
1549 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Added public key authentication support to OPER and SILCOPER
1552 commands in the client library. Affected file is
1553 lib/silcclient/command.c.
1555 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1557 * Changed the get_auth_methdod client operation to be asynchronous.
1558 It can be async if the application resolves the authentication
1559 method from the server during the negotiation. Added new
1560 SilcGetAuthMeth completion callback that the application will
1561 call after resolving the authentication method.
1563 Added function silc_client_request_authentication_method that
1564 the application can use to resolve the authentication method
1565 from the server. Added also SilcConnectionAuthRequest callback
1566 that the library will call after the server has replied. The
1567 application can call this function if it does not know the
1568 current authentication method.
1570 Affected files are lib/silcclient/client.c and
1571 lib/silcclient/silcapi.h.
1573 * The Irssi SILC client now automatically resolves the authentication
1574 method incase any configuration information is not present (and
1575 currently there never is). The affected file is
1576 irssi/src/silc/core/client_ops.c.
1578 * Fixed public key authentication from the client library.
1579 Affected file lib/silcclient/protocol.c. Changed also the
1580 protocol specification about the public key authentication in
1581 the connection authentication protocol. The actual data to be
1582 signed is now computed with a hash function before signing.
1584 * Fixed the public key authentication from the server as well.
1585 Affected file silcd/protocol.c.
1587 * Removed the mlock()'s from the memory allocation routines.
1588 Affected file lib/silcutil/silcmemory.c. The ./configure does
1589 not check anymore for the mlock(). Affected file is
1592 * Fixed USERS command in server to allow the execution of the
1593 command for private and secret channels if the client sending
1594 the command is on the channel. Affected file silcd/command.c.
1596 * Fixed silc_client_get_clients_local to return the clients
1597 count correctly. It could return wrong value. Affected file
1598 lib/silcclient/idlist.c.
1600 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1602 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1603 types. The assembler optimizations seemed not to like 64-bit
1604 data types. The assmebler optimizations thus are now enabled
1605 also for BSD systems as opposed to only enable them for Linux.
1607 * Do not check for threads at all on BSD systems. Affected
1608 file configure.in.pre.
1610 * Removed -n and -h options from the Irssi SILC Client since
1611 they are not used in silc.
1613 * Fixed the prime generation to assure that the first digit
1614 of the generated random number is not zero since our conversion
1615 routines does not like number strings that starts with zero
1616 digit. If zero digit is seen the random number is regenerated.
1617 This caused some corrupted RSA keys when the zero first digit
1618 was met. Affected file lib/silcmath/silcprimegen.c.
1620 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1622 * Fixed WIN32 configuration in the ./configure script.
1623 Fixed to include xti.h on environments that has it.
1624 Patches by Carsten Ilchmann and andrew.
1626 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1628 * Changed the silc_id_create_client_id to be collision
1629 resistant. It is now assured that there cannot be created
1630 two same client ID's. I suspect that some weird bugs in
1631 the server were actually caused by duplicate Client IDs.
1632 Affected file silcd/serverid.[ch]. A router receiving
1633 new ID now also assures and informs the sending server
1634 if the ID caused collision.
1636 * Changed the silc_id_create_channel_id to also assure that
1637 there are no collisions.
1639 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Statement about ignoring the Mutual Authentication flag when
1642 performing rekey with PFS was a bit misleading. It is ignored
1643 if it was set in the initial negotiation, it cannot be even
1644 set in the rekey. Fixed in the ke-auth draft. Started the
1645 new versions of the protocol drafts in the doc/.
1647 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * Fixed a bug in silc_client_command_identify_save when saving
1650 new channel information. The channel name was no duplicated
1651 and caused crash on exit. Affected file is
1652 lib/silcclient/command_reply.c.
1654 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1656 * Fixed the getkey command handling in the server. Send just
1657 empty OK reply to the sender if the key could not be fetched
1658 (but everything else was ok, like the key just was not available).
1659 Changed the public key parameter to optional in the protocol
1660 specs so that empty OK reply can be sent. Affected file
1663 Added a message to Irssi SILC client to tell to user if the
1664 server did not return a public key.
1666 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Fixed a channel key regeneration bug. It registered new
1669 timeout tasks exponentially until all system resources were
1670 used. Affected file silcd/server.c.
1672 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1674 * Added the SILC Document generator to the scripts/silcdoc.
1675 It can be used to generate the Toolkit Reference Manual out
1676 of the source tree. Internally it will also use the RoboDoc
1677 generator now imported in util/robodoc.
1679 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1681 * Added couple of return's in rekey protocol if error orccurred
1682 during the protocol. The execution must be terminated.
1683 Affected file silcd/protocol.c. Also, terminate the protocol
1684 always with timeout.
1686 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * The client's Client ID was created initally from the wrong
1689 nickname (it could have been in format nick@host) in the
1690 silc_server_new_client. Affected file silcd/packet_receive.c
1692 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * Added some SILC_LOG_ERROR's to various error conditions
1695 if client could not be added to ID cache. Affected files
1696 silcd/packet_receive.c and silcd/server.c.
1698 * When client's sock->user_data is freed, NULL also the
1699 client->router and client->connection pointers. Added check
1700 for these pointers being NULL to various places around the
1701 code. Affected file silcd/server.c.
1703 * Added client->data.registered == TRUE checks to various
1704 places around the code to assure that unregistered client's
1705 are not handled when it is not allowed. Affected file
1708 * Added `bool registered' fields to all
1709 silc_idlist_[server|client]_get_* routines to indicate whether
1710 the fetched client needs to be registered or not. Affected
1711 file silcd/idlist.[ch].
1713 * Add your own entry as registered to the ID cache in the
1714 server. Affected file server.c.
1716 * Fixed a bug in silc_server_new_server. The SilcServer was
1717 set as the new server's context instead of SilcServerEntry.
1718 This naturally caused some weird bugs.
1720 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1722 * Do not delete the channel rekey task when adding it
1723 for in silc_server_create_channel_key.
1725 * Changed the silc_server_create_channel_key to return
1726 TRUE or FALSE to indicate the success of the channel key
1729 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1731 * Fixed MSVC++ project files and added missing files to
1732 Makefiles under win32/.
1734 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * Do not add TCP_NODELAY flag if the operating system
1737 does not have it defined. Affected files are
1738 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1740 * Fixed buffer overflow from Irssi SILC Client. Affected
1741 file irssi/src/fe-common/core/themes.c.
1743 * Fixed double free in client library in the file
1744 lib/silcclient/client.c when disconnecting from server.
1746 * Applied double free patch from cras to Irssi SILC client.
1747 Affected files irssi/src/core/[modules/expandos].c
1749 * Fixed the disconnection handling to Irssi SILC Client.
1750 The application must call silc_client_close_connection
1751 in ops->connect client operation in case of failure of
1752 the connection. Affected file is
1753 irssi/src/silc/core/client_ops.c.
1755 * Do not set sock->protocol to NULL in the function
1756 silc_client_close_connection after executing the protocol's
1757 final callback since the sock might not be valid anymore.
1758 Affected file lib/silcclient/client.c.
1760 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1762 * Do not enable SILC_THREADS if the linking with libpthread
1763 did not happen. Affected file configure.in.pre.
1765 * Added notion to protocol specification that server must
1766 verify the sent authentication payload with CMODE when
1767 setting the channel founder key. Implemented it to the
1768 server. Affected file silcd/command.c.
1770 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1772 * Added _EXTRA_DIST SILC distribution variable to the
1773 distributions file. It is used to conditionally add extra
1774 files or directories to the specific distribution. Affected
1775 files ./prepare, Makefile.am.pre and distributions.
1777 Removed the `_' from the start of the distribution names.
1780 * Added README.WIN32 for instructions to compile the Toolkit
1783 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1785 * Fixed a double free in disconnection in the server. Affected
1786 file is silcd/server.c.
1788 * Fixed the lib/silcske/groups.c to work now also with GMP
1789 MP library. The string conversion did not work when using
1790 specific base and the base is indicated in the string as well.
1792 * Created win32/ directory which now includes MSVC++ specific
1793 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1794 It will appear only in the toolkit distribution
1796 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Changed the key material distribution function in case when
1799 the hash output is too short. The data is now concatenated
1800 a bit differently than it used to. Made the change to the
1801 SKE protocol specification.
1803 * Added better GMP detection to configure.in.pre. A patch
1806 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Fixed a minor bug in SKE that might cause some problem on
1809 some platforms. Affected file lib/silcske/silcske.c.
1811 * Added the cookie checking for initiator in the SKE. It checks
1812 that the responder returns the sent cookie unmodified. The
1813 affected file is lib/silcske/silcske.c. Added new SKE
1814 error type INVALID_COOKIE that can be sent during the
1815 negotiation. Fixed some memory leaks as well.
1817 * Added the "invalid cookie" error message to Irssi SILC client's
1820 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * Added `task_max' field to the SilcClientParams to indicate
1823 the maximum tasks the scheduler can handle. If set to zero,
1824 default values are used. Affected file lib/silcclient/silcapi.h.
1826 * Fixed memory leaks in silc_client_close_connection. Affected
1827 file lib/silcclient/client.c.
1829 * Added silc_client_del_client_entry to client library to free
1830 all memory of given client entry. Affected file is
1831 lib/silcclient/idlist.[ch].
1833 * Added new functions silc_client_del_channel and
1834 silc_client_del_server to delete channel and server entries.
1835 Affected file lib/silcclient/[silcapi.h/idlist.c].
1837 * Removed silc_client_del_client_by_id from silcapi.h.
1839 * Fixed the INFO command to return the server's own info
1840 correctly when querying by Server ID. Affected file is
1843 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Removed the non-blocking settings in WIN32 code in the
1846 silc_sock_[read/write] and added SleepEx instead. Affected
1847 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1848 of input data is now checked with FIONREAD and ioctlsocket.
1850 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Call silc_schedule_task_del_by_context in the
1853 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1854 Affected file lib/silccore/silcprotocol.c.
1856 * Call silc_protocol_cancel for active protocols in the
1857 silc_server_close_connection if the funtion
1858 silc_server_free_sock_user_data has not been called.
1859 Affected file silcd/server.c.
1861 * Generic tasks cannot be deleted using the del_by_fd
1862 task deleting function since generic tasks does not match
1863 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1865 * Added a notion to SILCOPER help file that the SILCOPER works
1866 only on router server, not on normal server.
1868 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1870 * Added for WIN32 support for the new scheduler as well.
1871 Affected file lib/silcutil/win32/silcwin32schedule.c.
1873 * Fixed the SHA1 implementation to work on various platforms.
1875 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1877 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1878 API. It is part of the scheduler now. Everything else is
1879 as previously but some functions has changed their names.
1880 Checkout the lib/silcutil/silcschedule.h for the interface.
1881 Updated all applications to use the new interface. Affected
1882 files are lib/silcutil/silcschedule.[ch].
1884 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Found a bug in the SKE implementation. The HASH value,
1887 specified by the protocol, was not computed correctly. The
1888 public key of the responder was not added to the computation
1889 even though it is mandatory. Affected file lib/silcske/silcske.c.
1890 This unfortunately causes incompatibilities with older
1891 clients and servers.
1893 * Added WIN32 specific network init and uninit functions:
1894 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1895 the Winsock2. Affected file lib/silcutil/silcnet.h and
1896 lib/silcutil/win32/silcwin32net.c.
1898 * Set the socket always to nonblocking mode on WIN32 after
1899 reading data or writing data. Affected file is
1900 lib/silcutil/win32/silcwin32sockconn.c.
1902 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Fixed various compilation problems under WIN32. Affected
1905 files lib/silcutil/win32/silcwin32thread.c and
1906 lib/silcutil/win32/silcwin32schedule.c.
1908 * Removed all _internal.h #includes from public header
1909 files. Internal headers must never be included from
1912 Removed also the lib/silcske/payload_internal.h file.
1914 * All include files that may be needed (public and some others
1915 included by the public headers) by application developers are
1916 now copied to the ./includes directory. It does not copy any
1917 internal headers. Affected file Makefile.defines.pre and all
1918 Makefile.am's under lib/ and subdirs.
1920 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * Do not change the ~/.silc directory's permissions automatically.
1923 Affected file irssi/src/silc/core/clientutil.c.
1925 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1927 * Do not cancel the protocol in silc_server_close_connection
1928 it might cause recursion. Now cancelled in the function
1929 silc_server_free_sock_user_data. Affected file silcd/server.c.
1931 * Fixed the silc_server_remove_clients_by_server to regenerate
1932 the channel keys correctly finally. Added also new function
1933 silc_server_remove_clients_channels to actually do it.
1934 Affected file silcd/server.c.
1936 * Fixed the silc_server_new_channel to not crash by giving
1937 wrong router to the new channel. Affected file is
1938 silcd/packet_receive.c.
1940 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1942 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1943 which is given as argument to the silc_client_alloc now.
1944 It can be used to configure the client and set various parameters
1945 that affect the function of the client.
1947 * The USERS command in server did not check whether the channel
1948 is private or secret. Affected file silcd/command.c.
1950 * Added new argument to the USERS command in protocol specification.
1951 The USERS command now can take the channel name as argument
1952 as well. Added support for this in client and server and
1953 updated the protocol specs.
1955 * Completed the GETKEY command in client. It can be now used
1956 to fetch also servers public key not only some clients.
1957 Affected files lib/silcclient/command[_reply].c.
1959 * Added silc_client_get_server to return server entry by the
1960 server name. Affected files lib/silcclient/silcapi.h and
1963 * Redefined the IDENTIFY command in protocol specification to be
1964 more generic. It now can be used to query information about
1965 any entity in the SILC Network, including clients, servers and
1966 channels. The query may be based either the entity's name
1967 or the ID. Added support for this in both client and server.
1969 Affected files silcd/command.c and lib/silcclient/command.c
1970 and command_reply.c.
1972 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1973 the _from_client and _from_server functions. Affected file
1976 * Added silc_client_get_channel_by_id_resolve to the file
1977 lib/silcclient/silcapi.h to resolve channel information by
1978 its ID. Added also silc_client_get_channel_by_id that
1979 does not resolve it from the server.
1981 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * Added SilcServerEntry context into the client library
1984 to represent one server. The INFO command now allocates
1985 these to save the resolved server info. For now on the
1986 client library will also keep information about servers,
1987 connected and resolved with INFO.
1989 The INFO command now allocates the SilcServerEntry context
1990 and saves the server info there. The COMMAND_REPLY in
1991 the INFO now returns the parameters to application in
1992 same order as defined in the protocol specification.
1994 The entries are cached in the client->server_cache.
1996 * The INFO command is now issued after received the Client ID
1997 from the server. Affected file lib/silcclient/client.c.
1999 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2000 to the application as the mode changer might be server.
2001 It is guaranteed that NULL is not returned anymore to the
2002 application. Affected file lib/silcclient/client_notify.c.
2004 The ID Type is now also passed to the application so that
2005 it can check whether the returned entry is SilcClientEntry
2008 Added new function silc_client_get_server_by_id to return
2009 the server entry by ID. Affected files are the
2010 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2012 * Do not create the channel in the Irssi SILC Client when issuing
2013 the JOIN command but when received the sucessful JOIN command
2014 reply. Otherwise the channel might get created even though we
2015 could not join it. The Affected file is
2016 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2018 * Fixed a channel joining bug in router. The router must also
2019 check the channel modes, invite and ban lists etc. when serving
2020 the JOIN command sent by normal server. Affected file is
2021 silcd/command.c. The router now resolves the client's
2022 information from the server who sent the JOIN command if it
2023 does not know it, and processes the JOIN command only after
2026 * Changed the SilcCommandCb to take new argument; void *context2.
2027 Affected file lib/silccore/silccommand.h
2029 The second argument in the command callbacks in the server now
2030 includes the SilcServerCommandReplyContext if the command was
2031 called as pending command callback from the command reply.
2032 Otherwise it is NULL. When called as pending the status of the
2033 command reply will be checked and if it was erronous the
2034 error will be sent to the original sender of the command.
2035 This way the client always receives the error messages even
2036 though the server was actually the one who received the error
2037 when it resent the command to router, for example. Affected
2038 files silcd/command[_reply].[ch].
2040 * Fixed sending WHOWAS command's error message to client if
2041 the requested client could not be found. It was missing.
2044 * Changed the CMODE and CUMODE commands reply arguments in the
2045 protocol specification. The Channel ID is now sent in both
2046 of the commands to identify the channel. Implemented this
2047 new feature to the client and server. Affected files
2048 lib/silcclient/command_reply.c and silcd/command.c.
2050 * Made better checks for invite and ban lists in the JOIN
2051 command in server. Affected file silcd/command.c.
2053 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * The server now performs the incoming host IP/DNS lookup
2056 using the silc_socket_host_lookup and thus does not block
2057 the server anymore. Affected file silcd/server.c.
2059 * Completed the multi-thread support for SILC Scheduler in
2060 the lib/silcutil/silcschedule.c.
2062 * Fixed the configure.in.pre to detect the pthread correctly
2065 * Fixed a deadlock in silc_task_queue_wakeup in the file
2066 lib/silcutil/silctask.c.
2068 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * Added new function silc_schedule_wakeup that is used in
2071 multi-threaded environment to wakeup the main thread's
2072 schduler. It needs to be used when a thread adds a new task
2073 or removes a task from task queues. After waking up, the
2074 scheduler will detect the task queue changes. If threads
2075 support is not compiled in this function has no effect.
2076 Implemented the wakeup mechanism to both Unix and WIN32
2077 systems. Affected files are lib/silcutil/silcschedule.[ch],
2078 lib/silcutil/unix/silcunixschedule.c and the
2079 lib/silcutil/win32/silcwin32schedule.c.
2081 * Added new function silc_task_queue_wakeup to wakeup the
2082 scheduler by the specified task queue. Affected file
2083 lib/silcutil/silctask.[ch].
2085 * The silc_socket_host_lookup_start now wakes up the scheduler
2086 after adding the timeout task. Affected file is
2087 lib/silcutil/silcsockconn.c.
2089 * The silc_socket_host_lookup is synchronous now if the threads
2090 support is not compiled in. However, the callback is still
2091 called asyncronously through the scheduler, anyway. Affected
2092 file lib/silcutil/silcsockconn.c.
2094 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * Added new function silc_socket_host_lookup to perform
2097 asynchronous IP and FQDN lookups for the socket connection.
2098 Affected files lib/silcutil/silcsockconn.[ch].
2100 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2103 that may or may not compile the mutex support in.
2105 Changed the silc_mutex_alloc interface. It allocates the
2106 mutex now to the sent pointer and returns TRUE or FALSE.
2108 Affected file lib/silcutil/silcmutex.h.
2110 * Wrote the SILC Task Queue interface to support multi-threads.
2111 Affected file lib/silcutil/silctask.[ch].
2113 * Wrote the SILC Scheduler to support multi-threads. Affected
2114 file lib/silcutil/silcschedule.c.
2116 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2118 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2119 in lib/silcutil/win32/.
2121 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2123 * Defined SILC Mutex API and SILC Thread API and implemented
2124 them for Unix. Affected files are
2125 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2126 lib/silcutil/unix/silcunixmutex.c and
2127 lib/silcutil/unix/silcunixthread.c.
2129 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2131 * Fixed the silc_server_remove_clients_by_server's channel
2132 key re-generation. The hash table handling was incorrect
2133 and would not work with many channels. Affected file is
2136 * Fixed some memory leaks around the server code.
2138 * Rewrote the silc_server_get_users_on_channel to support IPv6
2139 based Client ID's. Affected file silcd/server.c.
2141 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2142 specification. However, a separate document must be written
2143 to define the detailed signing procedure and the payload
2144 associated with the flag. Defined the flag to the
2145 lib/silccore/silcchannel.h as well.
2147 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Changed the dynamic tables to static size tables in the
2150 lib/silccrypt/silchmac.c.
2152 * Removed GCC dependencies from the code. A patch by cras.
2154 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Do not show the error "Error receiving packet bla bla"
2157 in server if it really was not an error (-2 means that reading
2158 is pending). Affected file silcd/server.c.
2160 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2162 * Fixed a possible crash in silc_server_remove_clients_by_server
2163 in silcd/server.c. Fixed there also some memory leaks.
2165 * Fixed the silc_idlist_replace_client_id. It could replace
2166 wrong key in the hash table. Affected file silcd/idlist.c.
2168 * Do not check whether there are global users on the channel
2169 if the channel->global_users is FALSE. Affected functions
2170 silc_server_remove_from_one_channel and
2171 silc_server_remove_from_channels in silcd/server.c. Also,
2172 do not check if the removed client is local as we can be
2173 sure that global client was not removed from the channel
2174 and checking for global users is not needed.
2176 * The silc_server_remove_clients_by_server now re-generates
2177 the channel keys correctly for those channels that had
2178 clients removed from them. Affected file silcd/server.c.
2180 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2182 * Found the reason of random crashes in the server. We weren't
2183 ignoring the SIGPIPE signal (which can be sent in write())
2184 and it crashed the server. Affected file silcd/silcd.c.
2186 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Assure that sock->user_data is not NULL in the function
2189 silc_server_packet_send in silcd/packet_send.c.
2191 * Disconnect the remote connection if it could not be added
2192 to any ID lists in the server. The affected file is
2195 * Check in silc_server_packet_send[_real/dest] that the
2196 socket is not disconnecting and ignore the data if it is.
2197 Affected file silcd/packet_send.c.
2199 * Define inline to __inline on native WIN32 compilation.
2200 Affected file includes/silcwin32.h.
2202 * Added some explicit type casts for inline code since MSVC
2203 require them. Affected files lib/silcutil/silcbuffer.h,
2204 lib/trq/silcdlist.h and lib/trq/silclist.h.
2206 * Print warning in log files from now on if the packet
2207 decryption fails. Affected file silcd/server.c.
2209 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2211 * Changed the `say' client operation's interface to accept
2212 new `type' argument to indicate the type of the message sent
2213 by the library. The application may filter the library's
2214 messages according the type. The affected file is the
2215 lib/silcclient/silcapi.h.
2217 * Added two new functions to lib/silcclient/silcapi.h:
2218 silc_client_del_client and silc_client_del_client_by_id.
2219 Affected file lib/silcclient/idlist.c.
2221 * Moved the clientincludes.h from includes/ to silc/ and
2222 serverincludes.h from includes/ to silcd/.
2224 * The modes for the CMODE and CUMODE are now passed as
2225 uint32 for application with COMMAND_REPLY. The affected
2226 file is lib/silcclient/command_reply.c.
2228 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * /WHOIS without arguments shows client's own information.
2231 Affected file lib/silcclient/command.c.
2233 * Changed PING to not accept any arguments. The specs
2234 says that client can ping only the connected server so
2235 requiring an argument is not needed. Affected file is
2236 lib/silcclient/command.c.
2238 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Fixed a fatal bug in private message sending and reception
2241 encryption and decryption when using private message keys.
2242 The implementation was incorrect and did not follow the
2243 specification. It causd that some of the message were
2244 lost since it did not use the sending and receiving keys
2245 as the protocol suggests. This has been fixed and will cause
2246 incompatibilities with older clients when sending private
2247 message encrypted with private message keys. Affected files
2248 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2249 and various other in Irssi SILC Client.
2251 Added `responder' boolean argument to the functions
2252 silc_client_add_private_message_key[_ske] to indicate when
2253 the key is added as responder or initiator of the key
2256 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Removed the silc_ske_check_version function and created
2259 a SilcSKECheckVersion callback. Added also a function
2260 silc_ske_set_callbacks that is now used to set all SKE
2261 callbacks. The callback functions are not given to
2262 the SKE functions anymore, but this function is used to
2265 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2267 * Added `silc_version' argument to the silc_client_alloc
2268 to define the version of the application for the library.
2269 The library will use the version string to compare it
2270 against the remote host's (usually a server) version
2271 string. Affected file lib/silcclient/silcapi.h
2273 * Added the KE protocol context to Key Agreement context
2274 in client library so that we can abort the SKE if it
2275 is in process when we get timeout. Affected file is
2276 lib/silcclient/client_keyagr.c.
2278 * Do not resolve the client ID forever if it returns in the
2279 first time that such client does not exist. This was done
2280 for example with private message. Affected file is
2281 lib/silcclient/client_prvmsg.c.
2283 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2285 * Do not add regex.h for WIN32. The affected file
2286 includes/silcincludes.h.
2288 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2289 not work yet 100%. It generates the DLL's automatically
2290 when compiling with --with-win32 under cygwin.
2292 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * lib/contrib/regex.c is not compiled on WIN32.
2296 * Added silc_net_get_socket_opt function to the
2297 lib/silcutil/silcnet.h.
2299 * Added includes/silcwin32.h for WIN32 specific includes
2302 * Do not use ptime structure or any of the posix process
2303 functions on WIN32 in lib/silccrypt/silrng.c.
2305 * Added silc_gettimeofday to provide generic function
2306 for struct timeval on all platforms. Added the function
2307 to lib/silcutil/silcutil.h.
2309 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2311 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2312 library as they clearly belong there. As a plus side we
2313 can make the actual socket connection routines platform
2316 Added also new generic function silc_socket_read and
2317 silc_socket_write (that used to be silc_packet_[read/write].
2318 The implementation of these are platform specific.
2320 * Added WIN32 specific routines of silc_socket_[read/write]
2321 to lib/silcutil/win32/silcwin32sockconn.c.
2323 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Added preliminary support for native WIN32 compilation under
2326 cygwin (using the -mno-cygwin option for GCC) to the
2327 ./configure.in.pre. The --with-win32 now prepares the
2328 compilation for native WIN32.
2330 * Rewrote the SILC Scheduler interface in the file
2331 lib/silcutil/silcschedule.h. The scheduler is now context
2332 based and does not have anymore any global static scheduler.
2333 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2334 and created lib/silcutil/win32 directory for WIN32 based
2337 * Added Unix specific network routines to the
2338 lib/silcutil/unix/silcunixnet.c and the old
2339 lib/silcutil/silcnet.c includes now only generic routines.
2341 Added WIN32 specific network routines to the
2342 lib/silcutil/win32/silcwin32net.c.
2344 * Added Unix specific utility functions from the
2345 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2347 * Added WIN32 SILC Scheduler to the file
2348 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2351 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Do not handle JOIN notify in the server if the target client
2354 is not registered (idata->registered == FALSE). The affected
2355 file is silcd/packet_receive.c.
2357 * Update the nickrec->founder in event_cumode in the Irssi SILC
2358 client. Affected file irssi/src/silc/core/silc-channels.c.
2360 * Fixed the CUMODE_CHANGE notify handling in the server when
2361 server and router are announcing their clients on channels.
2362 Now the mode changes are saved and notified correctly. The
2363 affected file is /silcd/packet_receive.c.
2365 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2366 They really did not replace the cache entry in the ID Cache.
2367 Now they do that. Affected file silcd/idlist.c.
2369 * Fixed the KICK notify handling in the Irssi SILC client to
2370 update the channel records so that the kicked client does not
2371 appear to be on the channel. The affected file is
2372 irssi/src/silc/core/silc-channels.c.
2374 * Always update the conn->current_channel when executing command
2375 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2377 * Fixed the KILL notify handling in Irssi SILC client to remove
2378 the killed client on all channels.
2380 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2382 * Fixed the silc_parse_command_line to remove extra spaces
2383 from the start and end of the arguments. Affected file is
2384 lib/silcutil/silcutil.c.
2386 * Cancel and free any active protocol in the function
2387 silc_server_close_connection. Affected file silcd/server.c.
2389 * Cancel and free any active protocol in the function
2390 silc_client_close_connction. Affected file is
2391 lib/silcclient/client.c.
2393 * Do not execute the KILL command for clients that are in
2394 history (ie. they are not in the network). Affected file is
2397 * Fixed KILL notify handling, client does not crash anymore.
2398 Affected file irssi/src/silc/core/silc-channels.c.
2400 * Reduced the default packet buffer size from 2048 to 1024 in
2401 lib/silccore/silcpacket.c.
2403 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2404 counter to the SKE context that is incresed when the SKE library
2405 performs async operation outside the library. If the outside
2406 process frees the SKE context and FREED status will be set
2407 and the library will detect after the sync operation that the
2408 libary is freed. The affected files are
2409 lib/silcske/silcske[_status].[ch].
2411 * Resolve the client entry information in the function
2412 silc_client_channel_message to assure that NULL pointer is not
2413 passed as client entry to the application. */
2415 * Fixed the task timeout calculation to assure that there is
2416 never negative timeouts. The affected file is
2417 lib/silcutil/silcschedule.c.
2419 * Fixed the channel user mode notification sending in server.
2420 It was sent point-to-point to the router (or to server by router)
2421 but it needs to be destined to a channel. The routines now
2422 supports sending the channel user mode notifys to the channels
2423 when announcing clients and channels. Affected files are
2424 silcd/server.c and silcd/packet_receive.c.
2426 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2427 It did not actually replace the old channel entry in the cache.
2428 Affected file lib/silcclient/client_notify.c.
2430 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * Fixed a possible crash in silc_packet_send_prepare. It now
2433 assures always that there is enough space in the buffer and
2434 at the tail area of the buffer (for MAC).
2436 Fixed the inbound buffer reallocation in silc_packet_read.
2437 It was old code and did not handle the reallocation correctly.
2440 The affected file is lib/silccore/silcpacket.c.
2442 * Fixed buffer overflow in silc_parse_nickname in the file
2443 lib/silcutil/silcutil.c.
2445 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2447 * make install generates new server keys only if there is not
2450 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2452 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2453 Added check that if the NOREPLY is set then we will not send
2454 the away message. This avoids infinite loop of away messages
2455 if both clients are away. The affected file is
2456 lib/silcclient/client_prvmsg.c.
2458 * Fixed client crash if /NICK was given without arguments.
2459 Affected file lib/silcclient/command.c.
2461 * Server does not send the invite list in INVITE command back
2462 to the client if the list was not altered. Added this notion
2463 to the protocol spec as well. Affected file silcd/command.c.
2465 Fixed possible crash in INVITE command by checking the
2466 value of silc_server_get_client_route command.
2468 * Fixed the INVITE notify type handling. The arguments are now
2469 taken in correct order and client does not crash. The affected
2470 file is irssi/src/silc/core/silc-channels.c.
2472 Removed the "Inviting xxx to channel" message from the
2473 client library away and let the application handle it.
2474 Affected file lib/silcclient/command.c. Added that message
2475 to Irssi SILC client's message formats.
2477 * Fixed CMODE command crash in client. It now checks the
2478 amount of arguments correctly and does not crash. The affected
2479 file is lib/silcclient/command.c.
2481 * Do not create new channel automatically in silc_channels_join
2482 but check whether the channel by that name already exists.
2483 Affected file irssi/silc/core/silc-channels.c.
2485 * Do not send the SERVER_SIGNOFF to router if the disconnected
2486 entity was the router. Affected file silcd/server.c.
2488 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2489 SILC client as it was missing from there.
2491 Added the handling of the KICK notify to the Irssi SILC client
2492 as it was missing. Added "you have been kicked" message to
2493 Irssi SILC client's message modules formats.
2495 Added the handing of the KILL notify to the Irssi SILC client
2496 as it was missing. Added the kill message module formats
2499 The affected file is irssi/src/silc/core/silc-channels.c.
2501 * The router did not save the channel mode the server announced.
2502 Affected file silcd/packet_receive.c.
2504 * Fixed a possible crash in INFO command in server. If the
2505 server did not provide the server info it crashed. Affected
2506 file silcd/command.c.
2508 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2510 * Fixed the GETKEY command in the server to check also the
2511 global list. Otherwise the GETKEY would not work correctly
2512 in normal SILC server. Affected file silcd/command.c.
2514 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * Fixed GETKEY crash, it crashed if the command did not succseed.
2518 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2520 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2521 is now real and not just an macro interface to GMP.
2523 Removed the entire GMP from the source tree and imported new
2524 NSS MPI library instead. Reason for removing GMP is that it is
2525 extremely large and compiles extremely slow. The NSS MPI
2526 is only a few files and compiles in less than 10 seconds.
2527 The speed is also about the same as GMP. The MPI is imported
2528 to lib/silcmath/mpi.
2530 If the system has GMP installed we will still use the GMP.
2531 If it is not then the NSS MPI will be compiled.
2533 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2535 * Merged a long nickname (127 characters long) crash bugfix from
2536 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2538 * Merged a freed memory reference bugfix from Irssi CVS tree.
2539 Affected file irssi/src/core/commands.c.
2541 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2543 * Added the server's public key sving and verification to the
2544 server when performing the SKE. This was missing and the
2545 remote server's (or router's) public key was accepted without
2546 checking whether we have it previously or trust it at all.
2547 Affected file silcd/protocol.c.
2549 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Check in the silc_server_timeout_remote if protocol is active
2552 and make sure that the protocol's final callback is called so
2553 that all memory if freed. Affected file silcd/server.c.
2555 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * silc_server_whois_send_reply crashed the server if the nickname
2558 was 127 characters long. Affected file silcd/command.c.
2560 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Added sanity check to the silc_server_new_client. If the hostname
2563 is provided inside username then check that the provided hostname
2564 really is the same as the resolved one. If the hostname was not
2565 resolved then check it from the public key. Affected file is
2566 silcd/packet_receive.c.
2568 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2569 if the server disconnected us and the connection is not valid
2570 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2572 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2573 the library to the lib/silcutil/silcutil.[ch].
2575 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Close log file after open. Affected file
2578 lib/silcutil/silclog.c.
2580 * Check whether sock == NULL in silc_client_send_packet and return
2581 if it is. Affected file lib/silcclient/silcclient.c.
2583 * Check rec->entry == NULL in the Irssi SILC Client before
2584 sending the channel message. Affecte file is
2585 irssi/src/silc/core/silc-servers.c.
2587 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Merged a splitted window bugfix from Irssi CVS tree. The
2590 affected file is irssi/src/fe-text/textbuffer-view.c.
2592 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2593 It did not print nickname.
2595 * Improved the distributions system a bit.
2597 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2600 irssi/src/fe-text/gui-window.c.
2602 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2603 to in-active server. The affected file is
2604 irssi/src/silc/core/client_ops.c.
2606 * Resolve the client in USERS command reply if the entry does
2607 not have username resolved. The affected file is
2608 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2609 command to WHOIS command to really resolve stuff. The USERS
2610 is not used any more in any critical section so WHOIS can
2611 be used even though it might be slower than IDENTIFY.
2613 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2616 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Changed the protocol API a bit more consistent in the
2619 lib/silccore/silcprotocol.[ch].
2621 * Changed the following headers to ROBODoc format:
2623 lib/silccore/silcpayload.h
2624 lib/silccore/silcprotocol.h
2625 lib/silccore/silcsockconn.h
2627 All core library headers are now formatted.
2629 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Fixed a bug in Irssi SILC client; do not show that you are
2632 server/router operator if you really are not. Affected file is
2633 irssi/src/silc/core/client_ops.c.
2635 * Renamed silc_command_free_payload to silc_command_payload_free.
2636 Affected file lib/silccore/silccommand.h
2638 * Added silcmath.h to include the prototoypes of various routines
2639 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2642 * Changed the following headers to ROBODoc format:
2644 lib/silccore/silcchannel.h
2645 lib/silccore/silccommand.h
2646 lib/silccore/silcid.h
2647 lib/silccore/silcidcache.h
2648 lib/silccore/silcmode.h
2649 lib/silccore/silcnotify.h
2650 lib/silccore/silcpacket.h
2651 lib/silcmath/silcmath.h
2653 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Added checking to the server code not to start the server if
2656 ciphers and stuff are not configured properly. Affected files
2657 silcd/serverconfig.[h] and silcd/server.c.
2659 * Changed the layout of the header files of the public interfaces
2660 in the SILC libraries. The new layout supports ROBODoc
2661 documentation tool (and some others) so that it is easy to create
2662 a library reference manual. All the other headers and source
2663 code must still follow the CodingStyle document. Also source
2664 code must not include these ROBODoc stuffs, only the headers.
2665 Furthermore, all public interface headers must now be named
2666 by using `silc' prefix, example: silcapi.h, silccipher.h.
2667 Some files were renamed due to this. All the other headers
2668 must not be used as public interfaces. I will update the
2669 CodingStyle document later. Changed following headers, so far:
2671 lib/silcclient/silcapi.h
2672 lib/silccore/silcauth.h
2673 lib/silccore/silcprivate.h
2674 lib/silccrypt/silcdh.h
2676 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2680 * Removed silc_client_packet_send_flush from the client library
2681 as it is not needed. Affected file lib/silcclient/client.[ch].
2683 * Added printing of message of unresolved authentication method
2684 to the Irssi SILC client. Added it to the module formats.
2685 Removed the same message from the client library.
2687 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Added new distribution feature, DISTLABEL. Every distribution
2690 can define own preprocessor label that can be used in the
2691 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2692 file distributions, acconfig.h.pre and prepare.
2694 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2696 * Added Makefile.defines_int to include the actual definitions
2697 for Makefile.defines.in. Tested the new distribution system,
2698 created distributions and tested installation.
2700 * Added AWAY message printing to the Irssi SILC client. Added
2701 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2703 * Added SCONNECT command to call the SILC's CONNECT command.
2704 Cannot use CONNECT directly since Irssi uses that internally.
2705 Affected file irssi/src/silc/core/silc-servers.c.
2707 Added ACTION local command. It is same as ME command but takes
2708 the channel as mandatory argument.
2710 Rewrote some of the Irssi's help files to suite for SILC
2713 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * Added Makefile.defines[.in] that should for now on be included
2716 in all Makefile.am file in the source tree. That file includes
2717 all common compilation definitions for SILC source tree.
2719 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Minor changes to the ./prepare script to change the package
2722 name according the distribution name to the configure.in.
2724 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2726 * Created new distribution system. Added file `distributions'
2727 that defines all the distributions that can be created out of
2728 the SILC source tree. The ./prepare script now reads that
2729 file to determine how to prepare the distributions. The
2730 first argument to the ./prepare is the name of the distribution
2731 and second is the version of the distribution. If given
2732 without arguments it creates the default (toolkit) distribution
2733 with the default version (defined in ./prepare).
2735 All Makefile.am files that are subject to the distributions
2736 are now named as Makefile.am.pre. These are ./Makefile.am
2737 and lib/Makefile.am. Others may be changed later.
2739 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Added invite list, ban list, some key management and connection
2742 error message printing to module formats in the Irssi SILC client.
2744 * Added new silc_client_set_away_message to set the away message
2745 that is back to the person who sent private message. The
2746 affected file lib/silcclient/silcapi.h and the
2747 lib/silcclient/client_prvmsg.c.
2749 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2751 * Fixed the private message sending in the Irssi SILC client,
2752 added local command KEY to the Irssi SILC client.
2754 Added key management and key agreement message formats to the
2755 irssi/src/fe-common/silc/module-formats.[ch].
2757 Added USERS (alias WHO) printing, server/router operator
2758 indication and LIST command printing to the module formats.
2760 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2762 * Fixed channel joining notify handling, cumode notify handling
2763 from Irssi SILC client.
2765 * Added SILC specific module-formats to the Irssi SILC client so
2766 that SILC specific message hilighting, colors etc is possible.
2767 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2769 Added channel mode, channel user mode, actions, notices,
2770 whois and whowas printing to the the module-formats.c.
2772 * Fixed a bug in channel deletion in the server. The channel
2773 is not left to the cache even if the channel founder auth mode
2774 is set when there are no users anymore on the channel. Affected
2775 file silcd/server.c.
2777 * The silc_net_localhost now resolves the entire hostname including
2778 the domain name. Affected file lib/silcutil/silcnet.c.
2780 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2782 * Changed the ask_passphrase client operation to be ascynchronous.
2783 It has now a completion callback and a context that the
2784 application must call after it has got the passphrase from
2785 the user. Affected files lib/silcclient/silcapi.h,
2786 lib/silcclient/protocol.c, lib/silcclient/command.c and
2789 Added SilcAskPassphrase callback that the application calls
2790 to deliver the passphrase to the library.
2792 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2793 The public key verification and especially a certificate
2794 verification is asynchronous procedure.
2796 Added new SILC_SKE_STATUS_PENDING status to indicate the
2797 request is pending and a callback will be called to finalize
2800 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2801 indicate that remote end did not send its public key (or
2802 certificate), even though we require it. Added check for this
2803 condition in the SKE. This was a security bug, now fixed.
2805 Defined new SilcSKEVerifyCbCompletion callback that is called
2806 when the verification process is completed.
2808 The affected files lib/silcske/silcske_status.h and
2809 lib/silcske/silcske.[ch].
2811 * Changed the verify_public_key client operation to be async
2812 as well. Defined SilcVerifyPublicKey callback that is used to
2813 indicate the success of the public key verification process.
2815 Changed the server and client to use the new async client
2818 * Changed the Irssi SILC client's internal scheduler to be called
2819 twice as many times as it used to be. As a result the client
2820 should be a bit faster now. Affected file is
2821 irssi/src/silc/core/silc-core.c.
2823 * Added support to Irssi SILC client of asynchronous public key
2824 verification and passphrase inquiry. Affected file is
2825 irssi/src/silc/core/silc-core.c.
2827 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Do not say "You have left channel %s" in client library.
2830 Moved it to the application. Affected files are
2831 lib/silcclient/command.c and silc/client_ops.c.
2833 * Fixed silc_client_get_clients. Command context was not
2834 duplicated and was freed memory in the callback. Affected
2835 file lib/silcclient/idlist.c.
2837 * Do not say "you are now talking..." on JOIN command in the
2838 client library. The appliation must handle it.
2840 * Do not say ".. changed topic to" in command reply in the
2841 client libary. The application must handle it.
2843 * Fixed TOPIC command sending in the client library.
2845 * Fixed a memory leak in silc_client_command_free in the file
2846 lib/silcclient/command.c.
2848 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Imported a modified version of Irssi client to the source tree.
2851 The Irssi will be used to create a new client called
2852 Irssi SILC. Imported to irssi/.
2854 Added silc_core_init_finish function to the Irssi. Affected
2855 file irssi/configure.in.
2857 A lot changes in the Makefile.ams around the irssi tree.
2859 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * Do not rehash if the new size is same as the old size of the
2862 hash table, in the silc_hash_table_rehash*. The affected file
2863 lib/silcutil/silchashtable.c.
2865 * Replaced hash_table_del_by_context calls from the server
2866 (when channel->user_list and client->channels) to the
2867 hash_table_del as it is sufficient and faster.
2869 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2871 * Added silc_hash_table_list, silc_hash_table_get and the
2872 SilcHashTableList structure to provide an alternative way to
2873 traverse the hash table. The affected files are
2874 lib/silcutil/silchashtable.[ch].
2876 * Changed the server's idlist routines to use the hash table
2877 routines to optimize the code.
2879 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * Replaced the client entry's `channel' list and channel entry's
2882 `user_list' list to hash tables for optimized lookup. Changed
2883 the code to use the hash table interface around the code.
2884 Affected file lib/silcd/idlist.[ch].
2886 * Added `auto_rehash' boolean argument to the function
2887 silc_hash_table_alloc to indicate whether the hash table should
2888 auto-rehash when it thinks is appropriate time. It will
2889 increase the hash table size if the there is twice as much
2890 entries in the table than the size of the table, and will
2891 decrease the size if there are twice as less entries than
2892 the size of the table.
2894 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2898 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2900 * silc_idcache_purge_by_context deletes the entry now by context
2901 as it is supposed to do. Affected file lib/silccore/idcache.c.
2903 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2904 client is not anymore valid (WHOWAS givens the info) and not
2905 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2907 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Removed the `data' and `data_len' arguments from the ID Cache
2910 interfaces and added `name' argument. ID Cache does not handle
2911 anymore the binary data only a names associated with given ID.
2913 * When hashing a Client ID with silc_hash_id the entire ID is
2914 not hashed anymore, instead only the hash of the Client ID is
2915 hashed. This way we can access the Client ID from the cache
2916 with Client ID but with the hash of the ID (which is a hash of
2917 the nickname) as well without any difference in performance.
2919 Added also silc_idcache_find_by_id_one_ext to do one on one
2920 searching when we have the actual ID. Added also function
2921 silc_hash_client_id_compare. The affected files are
2922 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2924 * When hashing the name associated with a ID it is always done
2925 in lowercase. This way we can access the cache without worrying
2926 about case-sensitivity, even though, for example nicknames are
2929 * Fixed a bug in server with channel message sending. It put
2930 wrong ID type as destination ID. The affected file
2931 silcd/packet_send.c.
2933 * silc_idcache_del_by_context now deletes from all hash tables
2934 by context. Affected file lib/silccore/idcache.c.
2936 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Changed the client library to use the new ID Cache interface.
2939 Changes around the source tree.
2941 * Added silc_hash_table_rehash_ext to rehash with specific
2942 hash function. Affected file lib/silcutil/silchashtable.[ch].
2944 * Added silc_hash_string_compare to compare two strings in the
2945 hash table. Affected file lib/silcutil/silcutil.[ch].
2947 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Added new function silc_idcache_del_by_context into the
2950 lib/silccore/idcache.[ch].
2952 * Changed the server's ID list routines to use the new ID Cache
2953 interface. Changes around the source tree.
2955 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Added silc_hash_table_del[_by_context]_ext functions in to the
2958 lib/silcutil/silchashtable.[ch].
2960 Removed silc_hash_table_find_all* routines and added new
2961 silc_hash_table_find_foreach to replace them.
2963 Added silc_hash_table_replace_ext function as extended
2964 replacing function. Separated the simple hash table interface
2965 from the extended hash table interface in the file
2966 lib/silcutil/silchashtable.h.
2968 * Fixed minor bugs and changed it to use some of the new
2969 hash table functions in lib/silccore/idcache.c
2971 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2973 * Added new function silc_hash_table_find_all to return all keys
2974 in the hash table by the specified key. As the hash table is
2975 collision resistant it also makes it possible to have several
2976 duplicate keys in the hash table. This function may be used to
2977 find all of the keys from the hash.
2979 Added user_context arguments to the SilcHashFunction,
2980 SilcHashCompare and SilcHashDestructor to deliver user specified
2983 Added new fuctions silc_hash_table_find[_all]_ext to do
2984 extended lookup with specified hash and compare functions and
2985 specified user contexts.
2987 Added new function silc_hash_table_add_ext to add the key
2988 with specified hash function and user context.
2990 Added new function silc_hash_table_foreach to traverse all
2991 entrys in the hash table. Added SilcHashForeach callback
2994 Added new function silc_hash_table_del_by_context to delete
2995 the entry only if the context associated with the key matches.
2997 Affected files are lib/silcutil/silchashtable.[ch].
2999 * Removed silc_hash_[server/client/channel]_id and added just
3000 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3001 silc_hash_id_compare to compare two ID's using as the hash table
3002 comparison function. Added also silc_hash_data to hash
3003 binary data and silc_hash_data_compare to compare it.
3005 * Removed silc_idlist_find_client_by_hash as it is not needed
3006 anymore. Affected file silcd/idlist.[ch].
3008 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3009 to use internally the SilcHashTable. The new ID Cache is a lot
3010 faster than the old one. Some of the ID Cache interface was also
3011 rewritten and obsolete and stupid functions were removed.
3013 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3015 * Added entry_count field to the SilcHashTable to keep the number
3016 of the entries in the table. Implemented the function
3017 silc_hash_table_rehash. Added new function
3018 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3020 Fixed a minor bug in silc_hash_table_free.
3022 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3023 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3024 into the lib/silcutil/silcutil.[ch].
3026 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3028 * Implemented a collision resistant hash table into the
3029 lib/silcutil/silchashtable[ch]. See the header and the source
3030 for the SilcHashTable API.
3032 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3034 * Merged dotconf version 1.0.2 into lib/dotconf.
3036 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3038 * Do not compile anything in lib/silcsim/* if the SIM support
3039 is not enabled. The tree should now compile without problems
3042 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Compiled the SILC under cygwin. Compiled and tested briefly
3045 without problems. More tests needed. The SIMs didn't compile
3048 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3050 * Fixed possible crash in silc_get_username in the
3051 lib/silcutil/silcutil.c.
3053 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Fixed a va_arg in silc/client_ops.c.
3057 * Oops, RC5 routines were named AES and caused some problems
3058 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3060 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Added new SilcIDIP structure into the lib/silccore/id.h and
3063 replaced the old `ip' fields from all SILC ID's to that type.
3064 This is a step towards IPv6 support.
3066 The silc_id_get_len takes now the ID as an extra argument.
3067 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3068 both IPv4 and IPv6 based ID's.
3070 The affected files are lib/silccore/id.[ch] and other files
3071 around the tree using these routines.
3073 * Removed the ID length arguments in server from various
3074 silc_server_send_notify_* routines -> they are not needed
3077 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Fixed memory leak in silc_encode_pem_file in the file
3080 lib/silcutil/silcutil.c.
3082 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3084 * Check minor version as well in the SKE. Affected files are
3085 silcd/protocol.c and lib/silcclient/protocol.c.
3087 * Added --identifier option to the server so that an identifier
3088 can be when creating the public key for the server. Affected
3089 file is silcd/silcd.c.
3091 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3092 lib/silccrypt/silcpkcs.c.
3094 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Register default ciphers and stuff when using -C option with
3097 the server. Affected file sildc/silcd.c.
3099 * Put back the servers public key filename format, it is better
3100 than the new one. For now, the client keys are saved with the
3101 new filename format. The affected file silc/client_ops.c.
3103 * Implemented the Cipher API for the rest of the ciphers that
3104 did not implement it or implemented it the wrong way.
3106 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Register default ciphers and stuff when using the -S option
3109 in the client. Affected file silc/silc.c. Same also when
3110 creating new key pair with -C option.
3112 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Fixed the silc_verify_public_key client operation function to
3115 save the public keys differently. The fingerprint is now
3116 used as filename and not the hostname. This way also the
3117 client keys are saved uniquely and not with hostnames. The
3118 affected file is silc/client_ops.c.
3120 * Trimmed the silc_hash_fingerprint function to remove extra
3121 whitespaces from the end of the fingerprint. The affected
3122 file is lib/silccrypt/silchash.c.
3126 * Added silc_cipher_register_default function to register all
3127 default ciphers. It can be used when configuration files
3128 does not exist and the application does not want any specific
3129 ciphers in any specific order.
3131 The SilcDList is now used as silc_cipher_list dynamically
3132 allocated cipher list. Removed the static list all together
3133 and now all ciphers must be allocated to the dynamic list.
3134 The silc_cipher_alloc routine was changed to check only the
3137 All silc_cipher_* routines that used to return int returns
3140 The affected files lib/silccrypt/silccrypt.[ch].
3142 * The same thing was done to silc_hash_* as for silc_cipher_*
3143 routines. Affected files lib/silccrypt/silchash.[ch].
3145 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3146 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3147 Added also silc_pkcs_[un]register[_default] functions.
3148 Removed the data_context from the PKCS API.
3150 * Added silc_hmac_register_default function to register default
3151 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3152 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3153 to unregister all hmacs at once.
3155 * Register the default ciphers, hash functions, PKCSs and HMACs
3156 if client's configuration file does not exist. The affected
3159 * The client did not load the hash functions from the SIM
3160 modules at all. Added support for this. Affected file is
3161 silc/clientconfig.c.
3163 * When decoding public key with silc_pkcs_public_key_decode, check
3164 the supported algorithm only if PKCS are registered. Affected
3165 file lib/silccrypt/silcpkcs.c. The same was done with the
3166 silc_pkcs_private_key_decode.
3168 * Fixed the SILC List routines to keep the list always in order.
3169 It used to change the list's order when traversing the list but
3170 not it preserves the order. Affected file lib/trq/silclist.h.
3172 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Added the client library to use the SilcSocketConnection's
3175 reference counter (by silc_socket_dup) to prevent the bug that
3176 the socket object may be freed underneath async operation.
3178 * The name resolv library checking fixes in the configure.in.pre.
3181 * Created new version of the protocol drafts for future
3182 development. The -03 drafts are the ones that will be changed
3183 in the trunk now and the -02 will remain as they are.
3185 * Send list of CUMODE notifys to the router when announcing
3186 the channel users to the router. Affected file silcd/server.c.
3187 If the router receiving channel founder CUMODE for a channel
3188 that already has channel founder it will send CUMODE notify
3189 to the sender to remove the channel founder rights from the
3190 announced client. Affected file silcd/packet_receive.c.
3192 * The CUMODE notify may now use Server ID as well as the entity
3193 who changes the mode. Updated protocool specs.
3195 * Updated INSTALL and README files.
3197 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * New web pages in the http://silc.pspt.fi. The pages was
3204 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Implemented the [DenyConnectin] config section in the server.
3207 Added silc_server_config_denied_conn to check whether incoming
3208 connection is denied. Affected file silcd/serverconfig.[ch].
3210 * Do not check the ports when checking the incoming configuration
3211 data if the port is 0, meaning any. Affected file is
3212 silcd/serverconfig.c.
3214 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3216 * Fixed buffer overflow in silc_string_compare in the file
3217 lib/silcutil/silcutil.c.
3219 * Fixed double free in silc_server_command_leave in the file
3222 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Fixed the version checking in the server. Affected file is
3227 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Fixed the configuration data fetching when accepting new
3230 connections in the server. Affected file silcd/server.c.
3232 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * Added `sender_entry' argument to the function
3235 silc_server_packet_relay_to_channel so that we can check
3236 whether some destination actually belongs to the same route
3237 the sender belongs (ie, we must not resend the packet to the
3238 sender). Affected file silcd/packet_send.[ch].
3240 * Added `servername' field to the SilcClientEntry in the server
3241 to hold the name of the server where client is from. Affected
3242 file is silcd/idlist.h.
3244 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Moved the channel message encrypting in the router betwen
3247 router connections from silc_server_channel_message to the
3248 silc_server_packet_relay_to_channel since we want to check
3249 whether we have anybody channel before encrypting anything.
3250 Affected files silcd/packet_[receive/send].c.
3252 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Fixed the [AdminConnection] server config section to support
3255 multiple entries. Affected file silcd/serverconfig.c.
3257 * Added support into the server to check the validity of the
3258 incoming connection before executing any KE or authentication
3261 * The connection configuration is now saved to the KE and
3262 connection auth protocol contexts and not fetched anymore in
3263 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3265 * The local hosts listenning address and port is also resolved
3266 now when starting the server. We want to have the socket object
3267 to include the real address and port for the listener. Added
3268 new function silc_net_check_local_by_sock into the files
3269 lib/silcutil/silcnet.[ch].
3271 * Fixed a broadcast bug in server -> do not broadcast if we
3274 * Fixed a routing bug. Do not route broadcast packets ever.
3275 Broadcast packets must be processed always and not routed since
3276 they may be destined to some other host than yourself and thus
3277 would get routed without no good reason. Affected file is
3280 * Added function silc_server_config_is_primary_route to check
3281 whether primary router connection has been configured (a router
3282 configuration that we are initiating). If there is not, we
3283 will assume that there is only two routers in the SILC network
3284 and we will use the incoming router connection as our primary
3285 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3287 * Changed the order of the broadcasting. Broadcast _after_ the
3288 packet has been processed not before. Affected file is
3291 * Fixed a [ClientConnection] parsing bug. The port was never
3292 parsed correctly thus resulting to port 0. Affected file
3293 silcd/serverconfig.c.
3295 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3296 argument and did not set the broadcast packet flag. Affected
3297 file silcd/packet_send.c. Fixed same bug in the function
3298 silc_server_send_notify as well.
3300 * If we receive NEW_ID packet for our own ID in the server, ignore
3303 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Removed the nickname from the Private Message Payload.
3308 Updated the code and the protocol specs.
3310 * Updated protocol specs for submitting to the IETF.
3312 * Tweaked the Random Number Generator a bit. Affected file
3313 lib/silccrypt/silcrng.c. Exported a new function
3314 silc_rng_[global]_add_noise which can be used to add more
3317 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Do not parse packets with different timeout when protocol
3320 is active -> may cause problem with rekey. Affected file
3323 * When server receives signoff notify it must not create
3324 new channel key if the client is on any channels since the
3325 sender of the signoff notify will create it.
3327 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Added printing of error messages during SKE protocol from the
3330 failure packet sent by server during SKE. Affected file
3333 * Removed the client's failure_callback handling with timeout
3334 and handle it immediately when received.
3336 * The SKE library returned wrong type in SUCCESS and FAILURE
3337 packets. They must be 32 bit MSB not 16 bit MSB.
3339 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Ok, rewrote the logic of the re-key and now it seems to work.
3342 I tested it on high traffic with frequent re-keys without
3343 problems. Added hmac_receive (and renamed hmac to hmac_send)
3344 in SilcClientConnection in lib/silcclient/client.h and
3345 in SilcIDListData in silcd/idlist.h. Also, removed the
3346 SilcPacketParserContext's cipher and hmac fields as they are
3347 not needed anymore and actually caused some problems when
3348 the ciphers and hmac's changed underneath the packet parser.
3350 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * If re-key protocol is active then process the incoming packets
3353 synchronously since we must assure that icoming packets encrypted
3354 with the old key is processed before the new keys is set to
3355 use. This is true other packets than for REKEY packets.
3356 Affected file silcd/server.c. The same was done to client library
3357 as well, affected file lib/silcclient/client.c.
3359 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Fixed bug in client and server to accept the force send if
3362 the packet is send from silc_[server/client]_packet_process
3363 function. Otherwise the packets are never delivered, oops.
3365 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Disable force sending of packets when REKEY protocol is active.
3368 We must assure that no packet is sent directly when rekey is
3369 performed. All packets must be sent through packet queue.
3370 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3371 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3372 function is silc_[server/client]_packet_send_real to check
3375 * Replaced the SIM paths from example config files to
3376 /usr/local/modules. Also, make install creates now
3377 /usr/local/silc/logs directory to hold all the SILC server
3380 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3382 * Made the configure.in.pre work on Solaris. Patch by salo.
3384 * Made all ciphers compatible with non-x86 machines. Defined
3385 CBC mode macros into lib/silccrypt/ciphers_def.h.
3387 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3389 * Fixed the make install.
3391 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * When MAC computation fails the silc_packet_decrypt returned 0
3394 even though it was supposed to return -1. Fixed this. The
3395 affected file is lib/silccore/silcpacket.c.
3397 * Do not replace the config files in /etc/silc (in make install)
3398 if they already exist. Affected file ./Makefile.am.
3400 * Do not send re-key packets immediately but through packet queue.
3401 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3403 * Changed silc_net_check_host_by_sock to return FALSE if the
3404 IP/DNS could not be resolved. Though, it returns the IP address
3405 now even if it could not resolve it (but returns also FALSE).
3406 Affected file lib/silcutil/silcnet.[ch].
3408 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Added silc_pkcs_decode_identifier to decode the public key's
3411 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3412 Added also silc_pkcs_free_identifier. Added also new context
3413 SilcPublicKeyIdentifier.
3415 * Added -S option to the silc client. It is used to dump the
3416 contents of the specified public key file.
3418 * Changed the PKCS api to return the public key length when
3419 setting the public key.
3421 * Fixed a fatal bug in the public and private key file loading.
3422 Affected file lib/silccrypt/silcpkcs.c.
3424 * Execute the packet parsing for client with zero (0) timeout
3425 if the protocol is active. Affected file silcd/server.c.
3427 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Made the key generation options to the silcd program. Added
3430 -C option, equivalent to client's option.
3432 * Added new [ServerKeys] config section to the server. It
3433 configures the server's public and private key.
3435 * Defined generic Public Key Payload into the protocol
3436 specification to send specific type of public keys and
3439 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3440 public key or certificate.
3442 * Implemented the GETKEY command to the server and to the
3443 client library and on user interface.
3445 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Made preliminary `make install' work.
3449 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3451 * Added SilcServerRekey context into silcd/idlist.h.
3453 * Added the PFS support as defined in the specification to the
3454 SKE protocol. Affected files lib/silcske/*.c.
3456 * Added `ske_group' field to the SilcServerRekey context to hold
3457 the number of the SKE group that is used with PFS in re-key.
3458 Affected file silcd/idlist.h.
3460 * Added PFS re-key support to the server. Affected file is
3463 * Added silc_protocol_cancel to cancel execution of the next
3464 state of the protocol. Affected file is
3465 lib/silccore/silcprotocol.[ch].
3467 * Added the re-key support with and without PFS to the client
3468 library. Re-key is performed once in an hour, by default.
3470 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3471 Added silc_client_rekey_callback and silc_client_rekey_final.
3472 Affected files are lib/silcclient/protocol.[ch] and
3473 lib/silcclient/client.[ch].
3475 * Removed the `hmac_key' and `hmac_key_len' fields from the
3476 SilcClientConnection structure; not needed. Affected file is
3477 lib/silcclient/client.h.
3481 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Do not ask whether user wants to use the negotiated private key
3484 for private messages, just use it. Affected file is
3485 silc/local_command.c.
3487 * Added `send_enc_key' and `enc_key_len' fields to the
3488 SilcIDListData structure since they are needed in the re-key
3489 phase. Affected file is silcd/idlist.[ch].
3491 * Implemented the simple re-key protocol into the server.
3492 Affected files silcd/server.c and silcd/protocol.[ch]. The
3493 re-key will be performed once in an hour, by default.
3495 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3496 Added silc_server_rekey, silc_server_rekey_callback and
3497 silc_server_rekey_final.
3499 * Removed Tunneled flag from the protocol. Updated the code
3500 and the specifications.
3502 * Adde `pfs' field to the SilcIDListData to indicate whether
3503 the PFS is to be performed in the re-key. Affected file is
3506 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3508 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3509 int64 of at least the xintXX size. If void * is less that 4
3510 bytes uint32 * will be used. Defined bool as boolean.
3512 * Changed _ALL_ unsigned long and unsigned int to uint32,
3513 unsgined short to uint16 in the source tree.
3515 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3516 not handle clients that has entry->data.registered == FALSE.
3517 They are not in the network anymore. Affected file is
3520 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Implemented the sending of the SERVER_SIGNOFF notify in the
3523 server. Affected file is silcd/server.c.
3525 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3526 Added also silc_notify_payload_encode_args into the
3527 lib/silccore/silcnotify.[ch].
3529 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3530 Affected file silcd/packet_receive.c.
3532 * Implemented the SERVER_SIGNOFF notify handling in the client
3533 library. Affected file lib/silcclient/client_notify.c. Also,
3534 implemnted the printing of the SERVER_SIGNOFF info to the
3535 application. Affected file silc/client_ops.c.
3537 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3538 if the deleting was successful. Affected file silcd/idlist.[ch].
3540 * Added support for public key authentication in the connection
3541 authentication protocol in the client library. Affected file
3542 lib/silcclient/protocol.c.
3544 * Changed the server's silc_idlist_get_clients_by_* interface
3545 to support already allocated array so that new entries may be
3546 added to pre-allocated array. Affected file silcd/idlist.[ch].
3547 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3548 and command replies.
3550 * All command reply functions in the server now calls the
3551 pending command callback even if error occured. This way the
3552 error will be delivered to the client as well. Affected files
3553 silcd/command.c and silcd/command_reply.c.
3555 * Fixed INFO command to return local server's info if no server
3556 was provided. Affected file lib/silcclient/command.c.
3558 * Removed RESTART command for good. Updated the code and the
3561 * Rewrote parts of the task system. It is a bit simpler now.
3562 Removed unsued task priorities. The affected files are
3563 lib/silcutil/silctask.[ch].
3565 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3567 * Moved the USERS printing from the library to the application.
3568 Affected files lib/silcclient/command.c and silc/client_ops.c.
3570 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Added channel key re-key support. The re-key is perfomed
3575 only by the router and is done once in an hour. Added `rekey'
3576 field to the SilcChannelEntry in the server. Affected files
3577 silcd/server.c and silcd/idlist.h.
3579 * Added silc_task_unregister_by_context into the file
3580 lib/silcutil/silctask.[ch].
3582 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Added SILC_UMODE_GONE mode to indicate when the client is not
3585 present in the SILC network. Added also support to the local
3586 command AWAY that will set this mode. Added support of showing
3587 "xxx is gone" in WHOIS command. The USERS command shows the
3588 gone status as well.
3590 * Fixed setting server and router operator privileges in the
3591 server's UMODE command. Affected file silcd/command.c.
3593 * Merged the SKE KE1 and KE2 payloads into one payload. The
3594 new KE payload is equivalent to the old KE2 payload.
3596 Cleaned up the SKE Start Payload parsing. It now uses the
3597 simple buffer unformatting to do the parsing. A lot faster
3600 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3601 to the SKE that is used to indicate whether both of the SKE
3602 parties should perform authentication. By default only the
3603 responder performs authentication. By setting this flag also
3604 the initiator must do authentication. By default it is unset
3605 since in normal SKE case, client to server connection, only
3606 the responder should do authentication. When doing SKE between
3607 two clients both should perform authentication. Updated the
3608 code and the protocol specs.
3610 * A little fix to IDENTIFY command in the server. Search the
3611 client first by hash not nickname. Affected file is
3614 * Fixed the silc_client_close_connection to support closing
3615 the client to client connections wihtout deleting too much
3616 data. Affected file lib/silcclient/client.c.
3618 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3619 are received if protocol used to be active but is not anymore
3620 the application would crash due to NULL pointer dereference.
3621 Affected files silcd/server.c and lib/silcclient/client.c.
3623 * Added `hash' field to the SilcClientConnection to include
3624 the hash function negotiated in the SKE protocol.
3626 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3627 to set the channel founder authentication data. A client can
3628 claim the founder rights later by providing the authentication
3629 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3630 This way the channel founder can regain the channel founder
3631 privileges even it is left the channel. This works only on
3632 local server and the client must be connected to the same
3633 server to be able to regain the founder rights. Updated the
3634 protocol specs accordingly.
3636 Added support to the CMODE command in the client to set the
3637 founder auth data. Read the README to see how to set it.
3639 Added support to the CUMODE command to claim the founder
3640 rights. Read the README to see how to do it.
3642 Added support for the founder authentication to the Channel
3643 Entry in the server. Affected file silcd/idlist.h.
3645 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3646 server's CMODE command. Affected file silcd/command.c.
3648 * Added the following new functions into lib/silccore/silcauth.[ch]:
3649 silc_auth_get_method and silc_auth_get_data.
3651 * The server now saves the remote hosts public key to the
3652 SilcIDListData pointer. Affected file silcd/protocol.c.
3654 * The normal server now does not remove the channel entry from
3655 the cache if the founder authentication data is set. It used
3656 to remove it if the founder was the last one on the channel on
3657 the server and left the channel. The auth data is saved and
3658 if the channel is re-joined later the old entry is used with
3659 the old auth data. Affected files silcd/command_reply.c and
3662 * Removed the `pkcs' field from the SilcIDListData structure
3663 in the server; it is not used. Affected file silcd/idlist.h.
3665 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Fixed packet processing on slow links. Partial packets were
3668 never re-processed because the incoming data buffer was cleared
3669 by the application. Application must not directly clear the
3670 sock->inbuf, the packet processing routines handle it. Fixed
3671 this in client library and in server.
3673 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Fixed the WHOIS and IDENTIFY send reply function to really
3676 check whether to send list or just one entry. Affected file
3679 * Cleaned up the LEAVE command's channel key distribution. The
3680 affected file silcd/command.c.
3682 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3683 can enforce the channel mode as well. In that case the ID
3684 includes the ID of the server. The code now enforces the
3685 mode change if the router have different mode than the server.
3687 * The notify client operation with CMODE_CHANGE notify can now
3688 return NULL client_entry pointer if the CMODE was not changed
3689 by client. Application must check for this.
3691 * Added <Server ID> argument to INFO command to support server
3692 info fetching by Server ID.
3694 * Added silc_server_announce_get_channel_users to get assembled
3695 packets of channel users of the specified channel. Affected
3696 file silcd/server.[ch].
3698 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3699 was freed underneath the ID Cache.
3701 * Re-announce clients when the server received CHANNEL_CHANGE
3702 notify from the router. Affected file silcd/packet_send.c.
3704 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3707 crashed since it did not handle the fact that there is no cipher
3708 called "3" and didn't check the error condition. Now fixed.
3710 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3711 flag. It can be used to send message requests.
3713 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3715 * Implemented the RESTART command in the client.
3717 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3718 notice type messages. Added notice printing to the user
3721 * The channel keys are not re-generated if the channel's mode
3722 is PRIVKEY, ie private key on the channel exists. Affected
3723 files silcd/server.c and silcd/command.c.
3725 * Fixed a little bug in channel message delivery when channel
3726 private keys are set in the server. Affected file is
3727 silcd/packet_send.c.
3729 * Changed the setting on channel->on_channel = TRUE from the
3730 silc_client_save_channel_key to the JOIN command reply. The
3731 key payload is not received if the private channel key is set.
3732 Affected file lib/silcclient/command_reply.c and the
3733 lib/silcclient/client_channel.c.
3735 * When the CMODE_CHANGE notify is sent and the channel private
3736 key mode is removed the channel key must be re-generated in
3737 other cells as well. Added this support for the router in the
3738 silcd/packet_receive.c.
3740 * Added new local command NOTICE to send notice message on
3741 channel. Affected file silc/local_command.[ch].
3743 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Added new local command ME to the client. It is used to send
3746 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3747 some action. Affected file silc/local_command.[ch].
3749 * Changed channel_message and private_message client operations
3750 to deliver the message flags to the application. Added also
3751 the `flags' arguments to the silc_client_send_channel_message
3752 and silc_client_send_private_message functions. Affected file
3755 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Redefined the Private Message Payload to support private message
3758 keys and to support the new private message flags. Updated
3759 the protocol specs. Flags makes it possible to have for example
3760 CTCP style messages.
3762 * Added new type SilcPrivateMessagePayload and defined an API
3763 for it in the lib/silcclient/silcprivate.[ch].
3765 * Tested private message private keys successfully. Tested the
3766 private message key set, unset and list commands with the new
3769 * Redefined the Channel Message Payload to include the channel
3770 message flags (equal with private message flags) to support
3771 for example CTCP style messages.
3773 * Defined some of the message (for channel and private message)
3774 flags. Updated the protocol specs and added the flags to the
3775 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3777 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Added SilcKeyAgreementStatus type to the key agreement routines
3780 to indicate the current status and error if one occured.
3781 The status types are defined in the lib/silcclient/silcapi.h.
3783 * Added new local command KEY that is used to set and unset private
3784 keys for channels, set and unset private keys for private messages
3785 with remote clients and to send key agreement requests and
3786 negotiate the key agreement protocol with remote client. The
3787 key agreement is supported only to negotiate private message keys,
3788 it currently cannot be used to negotiate private keys for channels,
3789 as it is not convenient for that purpose.
3791 * Fixed a minor pending callback setting bug in the function
3792 silc_client_get_client_by_id_resolve, now the function works.
3793 Affected file lib/silcclient/idlist.c.
3795 * Added function silc_net_get_local_port to get local bound
3796 port by socket. Added to lib/silcutil/silcnet.[ch].
3798 * Added `sockets' and `sockets_count' fields to the SilcClient
3799 object. They hold the sockets of the listenning sockets in
3800 the client. Listenning sockets may be for example the key
3801 agreement server. Affected file lib/silcclient/client.[ch].
3802 Added functions the silc_client_add_socket and the
3803 silc_client_del_socket. They are exported to the application
3806 * Added ~./silc/clientkeys to support other client's public keys.
3808 * Renamed verify_server_key client operation to verify_public_key
3809 and added one argument to indicate the type of the connection
3810 (server, client etc.).
3812 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3814 * Added silc_server_connection_auth_request to handle the
3815 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3816 silcd/packet_receive.[ch].
3818 * Added silc_server_send_connection_auth_request into the
3819 silcd/packet_send.c to send the connection auth request packet.
3821 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3824 * Fixed the public key authentication in responder side in the
3825 server. The `auth_data' pointer includes the SilcPublicKey
3826 not the path to the public key. Affected file silcd/protocol.c.
3828 * Implemented the public key authentication in the initiator side
3829 in the server. Affected file silcd/protocol.c.
3831 * Removed the [RedirectClient] config section from the server
3832 configuration. Is not needed and I don't want to implement it.
3834 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Cleaned up the CMODE command in the server. It now works
3837 correctly and supports all the modes defined in the protocol.
3838 Affected file is silcd/command.c.
3840 * Added `hmac_name' field to the SilcChannelEntry in the server
3841 to hold the default HMAC of the channel. It can be set when
3842 creating the channel (with JOIN command). Affected files
3845 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3846 type to indicate the change of the current cipher and hmac
3847 on the channel. Client can safely ignore the <cipher> argument
3848 (if it chooses to do so) since the CHANNEL_KEY packet will
3849 force the channel key change anyway. The <hmac> argument is
3850 important since the client is responsible of setting the new
3851 HMAC and the hmac key into use.
3853 * Fixed the CMODE command in the client library as well.
3855 * Tested CMODE command in router environment successfully.
3857 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Show the version of the remote client (or server) when connecting
3860 to the server. It is logged to the log file. Affected file
3861 is silcd/protocol.c.
3863 * Fixed the KILLED notify handling in the client library. The
3864 client must be removed from all channels when receiving the
3867 Also, do not remove the client entry when giving the KILL
3868 command but when the KILLED notify is received.
3870 * Removed silc_idlist_find_client_by_nickname from the server.
3871 Not needed anymore. Affected files silcd/idlist.[ch].
3873 * Implemented the CHANNEL_CHANGE notify type handling to the
3874 server. Affected file silcd/server.c.
3878 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Added silc_server_send_notify_invite to send the INVITE
3881 notify between routers.
3883 * Implemented the INVITE command correctly to the server.
3885 * Implemented the INVITE notify type handling in the server.
3887 * Implemented the INVITE command to the client library and on the
3890 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Added function silc_server_get_client_resolve to find the
3893 client entry by ID from all ID lists and then resolve it
3894 (using WHOIS) if it cannot be found. Affected file is
3897 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Implemented the BAN command to the client library.
3901 * The JOIN command in the server now checks the invite list
3904 * Changed the silc_command_reply_payload_encode_va and the
3905 silc_command_payload_encode_va to support that if argument is
3906 NULL it ignores and checks the next argument. Affected file
3907 lib/silccore/silccommand.c.
3909 * Added silc_server_send_notify_ban to send the BAN notify
3910 type between routers.
3912 * Chaned the silc_notify_payload_encode to support that if
3913 argument is NULL it ignores and checks the next argument.
3914 Affected file lib/silccore/silcnotify.c.
3916 * Tested ban lists in router environment successfully.
3918 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Implemented BAN command to the server, in silcd/command.[ch].
3922 * Removed the BAN and INVITE_LIST modes from the CMODE command
3925 * Added function silc_string_match to regex match two strings.
3926 Affected files lib/silcutil/silcutil.[ch].
3928 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Redefined parts of the SilcChannelEntry in the server to support
3931 the new ban and invite lists.
3933 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Redefined the INVITE command. The same command can be used to
3936 invite individuals to the channel but also to manage the invite
3937 list of the channel (to add to and remove from the invite list).
3938 Updated the protocol specs.
3940 * Added new command SILC_COMMAND_BAN that can be used to manage
3941 the ban list of the channel. Updated the protocol specs.
3943 * Removed the channel modes: the SILC_CMODE_BAN and the
3944 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3945 in the CMODE command. The equivalent features are now available
3946 using INVITE and BAN commands. Updated the protocol specs.
3948 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3949 in the network about change in the current ban list. The notify
3950 type is not used by the client.
3952 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3953 support the invite lists.
3955 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Added new function silc_string_regexify that converts string
3958 including wildcard characters into regex string that can
3959 be used by the GNU regex library. Added into the file
3960 lib/silcutil/silcutil.[ch].
3962 Added silc_string_regex_combine to combine to regex strings
3963 into one so that they can be used as one regex string by
3964 the GNU regex library. Added into the file
3965 lib/silcutil/silcutil.[ch].
3967 Added silc_string_regex_match to match two strings. It returns
3968 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3970 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3972 * Imported GNU regex to the soruce tree into lib/contrib.
3973 Fixed some compiler warning from the regex.c.
3975 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3977 * Fixed MOTD command in the server to work in router environment.
3979 * Fixed the MOTD command in the client library to support
3980 the server argument in the command.
3982 * Added `nickname_len' argument to the silc_idlist_add_client
3983 in the server, as the `nickname' argument may be binary data
3986 * Added silc_idlist_get_channels to return all channels from
3989 * Implemented LIST command to the server. Affected file is
3992 * Implemented the LIST command to the client library and on the
3995 * Added [<user count>] argument to the LIST command reply.
3996 With private channels the user count is not shown.
3998 * Updated TODO and README.
4000 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * The client entry's data.registered must be TRUE even with
4003 global client entry on global client list. The data.registered
4004 is used to check whether the client is anymore in the network,
4005 for example with WHOWAS command so it must be valid.
4007 * Fixed the WHOWAS command in the server. It now actually works
4008 in router environment. Added function into silcd/command_reply.c
4009 silc_server_command_reply_whowas_save.
4011 * Added silc_idlist_purge function to the silcd/idlist.c
4012 to periodically purge the ID Cache.
4014 * Fixed INFO command in the server. It works now in router
4015 environment. Added <server name> argument to the INFO command
4016 reply. Updated the protocol specs.
4018 * Fixed minor bug in silc_idcache_purge to not purge if the
4019 expire value is zero.
4021 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4022 they were buggy because of the WHOWAS information.
4024 * Fixed local command MSG to handle the async resolving of
4025 the remote client properly. It used to fail the first MSG.
4026 Affected file silc/local_command.c.
4028 * Added `data_len' field to SilcIDCache context.
4030 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Update TODO. Todo in commands in the server.
4034 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4037 used by routers as broadcast packet to inform other routers
4038 about the changed user mode.
4040 Implemented the notify handling in the server. Affected file is
4041 silcd/packet_receive.c. Added the function
4042 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4044 * Added new generic Channel Payload and deprecated the New Channel
4045 Payload. The New Channel Payload is now the generic Channel
4048 * Added new argument `mode' to the silc_server_send_new_channel
4049 as it is required in the Channel Payload now.
4051 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4052 and created a new and real SilChannelPayload to represent the
4053 new generic Channel Payload. Implemented the encode/decode
4054 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4056 * Added silc_server_get_client_channel_list to return the list
4057 of channels the client has joined for WHOIS command reply.
4058 Affected file silcd/server.[ch].
4060 * Implemented the channel list sending in the WHOIS command reply
4061 in server and in the client.
4063 Implemented the channel list displaying on the user interface
4064 as well. Affected file silc/client_ops.c.
4066 * Added silc_channel_payload_parse_list to parse list of Channel
4067 Payloads. It returns SilcDList list of SilcChannelPayloads.
4068 Client for example can use this function to parse the list of
4069 channels it receives in the WHOIS command reply. The caller
4070 must free the list by calling silc_channel_payload_list_free.
4071 Affected files lib/silccore/silcchannel.[ch].
4073 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Added one new argument <user mode> to the WHOIS command reply
4076 to return the mode of the user in SILC. Updated the protocol
4079 Implemented it to the server and client.
4081 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4083 * Fixed the mode printing on the user interface on joining.
4084 Affected file silc/client_ops.c.
4086 * Implemented the UMODE command and user modes in general to the
4087 client library and to the user interface.
4089 * Implemented the UMODE command to the server.
4091 * The server now sends UNKNOWN_COMMAND error status if client sends
4092 unknown command. Affected file silcd/command.c.
4094 * All server commands now handle the command identifier the right
4095 way when sending the command reply to the client. The client can
4096 use to identify the command replies with the identifier.
4098 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4100 * Added silc_server_get_client_route to resolve the route to
4101 the client indicated by the client ID. Affected file is
4104 * Added silc_server_relay_packet as general function to relay
4105 packet to arbitrary destination. This deprecates functions
4106 like _send_private_message_key, _relay_notify etc. Affected
4107 file is silcd/packet_send.[ch].
4109 Removed silc_server_send_key_agreement,
4110 silc_server_send_private_message_key and
4111 silc_server_packet_relay_notify functions from the file
4112 silcd/packet_send.[ch].
4116 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4117 server. Affected file silcd/packet_receive.[ch].
4119 * Implemented the KILL command to the client. Implemented the
4120 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4121 Affected files lib/silcclient/command[_reply].c and
4122 lib/silcclient/client_notify.c. Implemented the KILL notify
4123 printing in the user inteface.
4125 * Fixed a lot silc_parse_nick memory leaks from the client
4126 library in the file lib/silcclient/command.c.
4128 * Changed the silc_server_send_notify_on_channels's `sender'
4129 argument from SilcSocketConnection to SilcClientEntry to
4130 check the sender as entry and not as connection object and not
4131 to send to the client provided as argument. The affected file
4132 is silcd/packet_send.[ch].
4134 * The notify packets that are destined directly to the client used
4135 to not to be processed by the server. Now changed that and the
4136 server processes all notify packets. After relaying the packet
4137 to the client the notify packet is processed in the server.
4139 * The silc_server_free_client_data now checks whether there is
4140 pending outgoing traffic for the client and purges the data to
4141 the network before removing the client entry.
4143 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4146 an client is killed from the SILC Network. Updated the protocol
4149 Added new function silc_server_send_notify_killed to the
4150 silcd/packet_send.[ch].
4152 * Added function silc_server_packet_relay_notify to relay notify
4153 packets that are destined directly to a client. In this case
4154 the server does not process the notify packets but merely relays
4155 it to the client. Affected file silcd/packet_send.[ch].
4157 Added also silc_server_packet_process_relay_notify to check
4158 whereto relay the notify. Affected file is
4159 silcd/packet_receive.[ch].
4161 * Implemented the KILL command to the server.
4165 * Added the backup schema desgined last fall to the protocol
4166 specs for everyone to see. The specification is in the
4167 *-spec-xx.txt draft and the packet type definitions for the
4168 backup routers is in *-pp-xx.txt draft. Thusly, added also
4169 new packet type SILC_PACKET_CELL_ROUTERS.
4171 * A big security problem in the implementation discovered. The
4172 signoff of an client did not cause new channel key generation
4173 which it of course should've done. The channel keys must be
4174 always re-generated when client leaves (or signoffs) the channel.
4175 The silc_server_remove_from_channels funtion now handles
4176 the channel key re-generation.
4178 * Added `sender' argument to the silc_server_send_notify_on_channels
4179 to not to send the client provided as argument. Affected file
4180 silcd/packet_send.[ch].
4182 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Implemented OPER and SILCOPER commands into the server and
4187 * Added silc_auth_verify and silc_auth_verify_data to verify
4188 the authentication directly from the authentication payload.
4189 It supports verifying both passphrase and public key based
4190 authentication. Affected file lib/silccore/silcauth.[ch].
4192 * Added `hash' field to the SilcIDListData structure. It is the
4193 hash negotiated in the SKE protocol. Affected file is
4196 * Slight redesigning of the SilcAuthPayload handling routines.
4197 Do not send SilcPKCS but SilcPublicKey as argument.
4199 * Implemented the public key authentication support to the
4200 serverconfig. The public key is loaded from the provided path
4201 and saved as authentication data to void * pointer. Thus,
4202 changed the unsigned char *auth_data to void *auth_data;
4204 * Fixed SHUTDOWN command to send the reply before the server
4205 is shutdown. :) Affected file silcd/command.c.
4207 * Fixed fatal bug in CONNECT command. The hostname was invalid
4208 memory and server crashed. Affected file silcd/command.c.
4210 * Fixed fatal bug in CLOSE command. The server_entry became
4211 invalid but was referenced later in the command. Affected file
4214 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4216 * Fixed fatal bug in failure packet handling. Server ignored
4217 the failure and thus crashed when it came.
4221 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4223 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4224 that the command may be executed only once in (about) 2 seconds.
4225 The old SILC_CF_LAG flag is same but allows command bursts up
4226 to five before limiting.
4228 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4229 server code. Various commands now includes the CF_LAG_STRICT
4230 flag to disallow any kind of miss-use of the command.
4232 * Fixed the silc_buffer_unformat to not to allocate any data
4233 if the length of the data is zero. It used to allocate the
4234 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4236 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Changed the format of AdminConnection configuration section
4239 in the server. Added username of the admin to the format.
4240 Affected files silcd/serverconfig.[ch].
4242 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4243 to return admin configuration data by host, username and/or
4246 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * Implemented WHOWAS command to the server. Added the functions:
4250 silc_server_command_whowas_parse,
4251 silc_server_command_whowas_send_reply,
4252 silc_server_command_whowas_from_client and
4253 silc_server_command_whowas_from_server
4255 * Added <Client ID> argument to the WHOWAS command reply. Updated
4256 the protocol specs accordingly.
4258 * Implemented WHOWAS command and command_reply to the client
4261 Implemented the WHOWAS printing on the user interface.
4263 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Added new argument to the WHOWAS command reply, the real name.
4266 It is an optional argument. Updated the protocol specs.
4268 * Added SilcIDCacheDestructor callback that is registered when
4269 the SilcIDCache is allocated. The callback is called when
4270 an cache entry in the ID Cache expires, or is purged from the
4271 cache. Added into lib/silccore/idcache.[ch].
4273 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4274 to destruct the client entries when the cache entry expires.
4275 Other ID Cache's in server and in the client library ignores
4278 * If the ID Cache entry's `expire' field is zero then the entry
4279 never expires. Added boolean `expire' argument to the
4280 silc_idcache_add function in the lib/silccore/idcache.[ch].
4281 If it is TRUE the default expiry value is used.
4283 * Added silc_server_free_client_data_timeout that is registered
4284 when client disconnects. By default for 5 minutes we preserve
4285 the client entry for history - for WHOWAS command.
4287 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Added support to the server to enforce that commands are not
4290 executed more than once in 2 seconds. If server receives
4291 commands from client more frequently, timeout is registered
4292 to process the commands. Affected file silcd/command.c.
4293 Added new function silc_server_command_process_timeout.
4295 * Changed NICK_NOTIFY handling in client library to check that
4296 if the client's nickname was changed, so there is no need to
4297 resolve anything from the server.
4299 * Removed error printing from the WHOIS and IDENTIFY commands.
4300 If error occurs then it is ignored silently in the client library.
4301 The application, however, may map the received error to
4302 human readable error string. The application currently maps
4303 the NO_SUCH_NICKNAME error to string.
4305 * Made the command status message public to the application. Moved
4306 them from lib/silcclient/command_reply.c to
4307 lib/silcclient/command_reply.h. The application can map the
4308 received command status to the string with the
4309 silc_client_command_status_message function.
4311 * Added check to the server to check that client's ID is same
4312 as the Source ID in the packet the client sent. They must
4315 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Added dist-bzip hook to the Makefile.am to make bzip2
4318 compressed distributions.
4320 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Server now enforces the maximum length for the nickname and
4323 the channel as protocol specification dictates. 128 bytes for
4324 nickname and 256 bytes for channel name.
4326 * Moved the WHOIS printing to the application. The client libary
4327 does not print out the WHOIS information anymore, the application
4328 must do it. Renamed silc_client_command_reply_whois_print to
4329 the silc_client_command_reply_whois_save.
4331 The client's idle time is also sent to the application now, and
4332 the idle is shown on screen.
4334 * Added silc_client_command_reply_identify_save to save the
4335 received IDENTIFY entries.
4337 * Do not check for channel private keys in message sending and
4338 reception if the channel does not have the PRIVKEY mode set.
4339 Affected file lib/silclient/client_channel.c.
4341 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4344 just surfaced after chaning the JOIN procedure.
4346 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Added silc_client_get_clients_by_list to get client entries
4349 from Client ID list, that is returned for example by JOIN
4350 and USERS command replies. The application should use this
4351 function for example when JOIN command reply is received to
4352 resolve the clients already on the channel (library does not
4353 do that anymore as USERS command reply is not used in the JOIN
4354 procedure anymore). Affected files lib/silcclient/silcapi.h and
4355 lib/silcclient/idlist.c.
4357 * JOIN command reply and USERS command reply returns now SilcBuffer
4358 pointers instead of unsigned char pointers when returning
4359 the client list and mode list.
4361 * Added <Client ID> argument to the JOIN command reply, mainly
4362 for the server to identify for which client the command was
4363 originally sent. Updated protocol specs accordingly.
4365 * Added SilcDlist private_key pointer to the SilcChannelEntry
4366 in the client to support the channel private keys. Affected
4367 file is lib/silcclient/idlist.h.
4369 * Added SilcChannelPrivateKey argument to the function
4370 silc_client_send_channel_message so that application can choose
4371 to use specific private ke if it wants to. If it is not provided,
4372 the normal channel key is used, unless private keys are set.
4373 In this case the first (key that was added first) is used
4374 as the encryption key.
4376 * Implemented the support for channel private key handling.
4377 Implemented the following functions:
4379 silc_client_add_channel_private_key,
4380 silc_client_del_channel_private_keys,
4381 silc_client_del_channel_private_key,
4382 silc_client_list_channel_private_keys and
4383 silc_client_free_channel_private_keys
4385 Affected file lib/silcclient/client_channel.c.
4387 * Added the support for the private keys in the channel message
4388 sending and encryption and in the message reception and
4389 decryption. Affected funtions are
4390 silc_client_send_channel_message and silc_client_channel_message.
4392 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Added SKE's key verify callback to the client library's
4395 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4397 * Removed the statement that server (or router) must send USERS
4398 command reply when joining to the channel so that the client
4399 knows who are on the channel. Instead, the client list and
4400 client's mode list is now sent in the JOIN command reply to the
4401 client who joined channel. This is better solution.
4403 * Added function silc_server_get_users_on_channel and function
4404 silc_server_save_users_on_channel to the silcd/server.[ch].
4406 * Removed function silc_server_command_send_users from the
4409 * Do not show topic on the client library anymore. The topic is
4410 sent in the command reply notify to the application and the
4411 application must show the topic now.
4413 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Added client searching by nickname hash into the IDENTIFY and
4416 WHOIS commands in the server as they were clearly missing from
4417 them. Affected file is silcd/command.c.
4419 * Fixed a bug in private message receiving in the client library.
4420 The remote ID was freed and it wasn't supposed, now it is
4423 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * Minor fix to the channel payload; allocate the data area, as it
4426 needs to be of specific length.
4428 * If the key agreement port is zero then the operating
4429 system will define the bound port. Affected files are
4430 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4432 * Added new function silc_channel_payload_decrypt into the file
4433 lib/silccore/silcchannel.[ch].
4435 * Moved the channel message etc, check from silc_packet_decrypt
4436 to applications. The library calls now a generic
4437 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4438 when the packet is either normal or special. This was done to
4439 allow more wide range of checking that was not allowed when
4440 the code was in library. Now applications can do virtually any
4441 checks to the packet and return to the library the decision how
4442 the packet should be processed. Affected files are
4443 lib/silccore/silcpacket.[ch].
4445 Added silc_server_packet_decrypt_check to the server and
4446 silc_client_packet_decrypt_check to the client library.
4448 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4449 to send with specified source and destination information.
4451 * Channel message delivery between routers was broken after the
4452 channel key distribution was fixed earlier. The channel key
4453 was used be to distributed to other routers as well which is not
4454 allowed by the protocol. Now this is fixed and channel keys
4455 really are cell specific and the channel message delivery between
4456 routers comply with the protocol specification.
4458 * Fixed various commands in server to check also the global list
4459 for the channel entry and not just the local list. The affected
4460 file silcd/command.c.
4462 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Added assert()s to buffer formatting and unformatting routines
4465 to assert (if --enable-debug) when error occurs. Affected
4466 file: lib/silcutil/silcbuffmt.c.
4468 * Changed to auto-reconnect to check whether the remote host is
4469 router and register the re-connect timeout if it is. It used
4470 to check that whether we are normal server, but router must do
4471 auto-reconnect with another router as well. Affected file
4474 * Removed the [<key len>] option from CMODE command as the cipher
4475 name decides the key length, nowadays. See the defined ciphers
4476 from the protocol specification.
4478 * Added [<hmac>] option to the CMODE command to define the HMAC
4479 for the channel. Added SILC_CMODE_HMAC channel mode.
4481 * Added [<hmac>] option for the JOIN command so that user can
4482 select which HMAC is used to compute the MACs of the channel
4485 * Added Hmac field to the Channel Message Payload. The integrity
4486 of plaintext channel messages are now protected by computing
4487 MAC of the message and attaching the MAC to the payload. The
4488 MAC is encrypted. Now, it is clear that this causes some
4489 overhead to the size of the packet but rationale for this is that
4490 now the receiver can verify whether the channel message decrypted
4491 correctly and also when private keys are set for the channel the
4492 receiver can decrypt the packet with several keys and check from
4493 the MAC which key decrypted the message correctly.
4495 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4496 lib/silccrypt/silccipher.[ch].
4498 * Added silc_hash_len to return the digest length into the
4499 lib/silcrypt/silchash.[ch].
4501 * Rewrote parts of Silc Channel Payload interface in the
4502 lib/silccore/silcchannel.[ch]. The encode function now also
4503 encrypts the packet and parse function decrypts it.
4505 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4507 * Fixed a minor formatting bug in the SKE's key material processing.
4508 It actually might have processed the keys wrong way resulting
4511 * Redefined the mandatory HMAC algorithms and added new algorithms.
4512 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4513 and hmac-md5 truncated to 96 bits. The mandatory is now
4514 hmac-sha1-96. Rest are optional (including the one that used
4515 to be mandatory). Rationale for this is that the truncated HMAC
4516 length is sufficient from security point of view and can actually
4517 make the attack against the HMAC harder. Also, the truncated
4518 HMAC causes less overhead to the packets. See the RFC2104 for
4521 * Added new [hmac] configuration section. The SKE used to use
4522 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4523 is of course wrong. The official names that must be proposed in
4524 the SKE are the ones defined in the protocol specification
4525 (hmac-sha1-96 for example). The user can configure any hmac
4526 using any hash function configured in the [hash] section. At
4527 least, the mandatory must be configured.
4529 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4531 * Added HMAC list to the SKE proposal list. It has now both
4532 hash algorithm list and HMAC list. This makes the protocol
4533 incompatible with previous versions. The SKE now seems to work
4534 the way it is supposed to work, for the first time actually.
4536 * Defined plain Hash algorithms to the protocol specification.
4539 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Implemented support for key agreement packets into the server.
4542 Added functions silc_server_key_agreement and
4543 silc_server_send_key_agreement. Other than these functions,
4544 server has nothing to do with this packet.
4546 * Added support for private message key packets into the server.
4547 Added functions silc_server_private_message_key and
4548 silc_server_send_private_message_key.
4552 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4553 called in the protocol's final callback instead in the END
4554 protocol state. This makes a little more sense and in the same
4555 time in client we can use the same protocol routines for normal
4556 key exchange and to key agreement packet handling as well.
4558 * Added to both client's and server's KE protocol context the
4559 SilcSKEKeyMaterial pointer to save the key material. We will
4560 bring the key material to the protocol's final callback by doing
4561 this. The final callback must free the key material.
4563 * Added SKE's packet_send callback into client's KE protocol
4564 context so that the caller can choose what packet sending function
4565 is used. This way we can use different packet sending when
4566 doing normal SKE when doing key agreement packet handling (in
4567 the key agreement packet handling we do not want to encrypt
4570 * Implemented the responder side of the key agreement routines
4571 in the client. The client can now bind to specified port and
4572 accept incoming key negotiation. The key material is passed
4573 to the application after the protocol is over.
4575 * Implemented the processing of incoming Key Agreement packet
4576 in the client. Added function silc_client_key_agreement to
4579 * Implemented the intiator side of the key agreement routines
4580 in the client. The client can now initiate key agreement with
4581 another remote client. The key material is passed to the
4582 application after the protocol is over.
4584 * Created client_keyagr.c to include all the key agreement
4587 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4588 SILC_TASK_CALLBACK except that it is not static.
4590 * Created client_notify.c and moved the Notify packet handling
4591 from the client.[ch] into that file.
4593 * Created client_prvmsg.c and moved all private message and
4594 private message key routines from the client.[ch] into that file.
4596 * Create client_channel.c and moved all channel message and
4597 channel private key routines from the client.[ch] into that file.
4599 * Changed silc_client_get_client_by_id_resolve to resolve with
4600 WHOIS command instead of IDENTIFY command, in the file
4601 lib/silclient/idlist.c.
4603 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Implemented the SKE's responder side to the Client library.
4607 * When FAILURE is received to the protocol do not trust it
4608 blindly. Register a timeout to wait whether the remote closes
4609 the connection as it should do it, only after that process the
4610 actual failure. This was changed to both client and server.
4612 * Added client_internal.h to include some of the structures
4613 there instead of client.h in lib/silcclient/.
4615 * Added function silc_task_unregister_by_callback to unregister
4616 timeouts by the callback function.
4618 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Some "Incomplete WHOIS info" errors has been appearing on the
4621 log files. Took away the entry->userinfo check from WHOIS
4622 reply sending. The entry->userinfo is now " " if client did not
4623 provide one. I thought this was fixed earlier but something
4624 is wrong still. Let's see if the error still appears.
4626 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Fixed a minor bug in the login when the channel key is
4629 re-generated in the server. It used to generate the key in
4630 wrong order and thus caused problems in the channel traffic.
4632 * Fixed a minor bug in channel key distsribution after
4633 KICK command. The key was not sent to the router even though
4636 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Added silc_ske_process_key_material_data as generic routine
4639 to process any key material as the SILC protocol dictates. The
4640 function is used by the actual SKE library but can be used by
4641 applications as well. This relates to the private message keys
4642 and the channel private keys since they must be processed the
4643 same way the normal SILC session keys. The protocol dictates
4644 this. Affected files: lib/silcske/silcske.[ch].
4646 Added also silc_ske_free_key_material to free the
4647 SilcSKEKeyMaterial structure.
4649 * Defined silc_cipher_set_key function to set the key for
4650 cipher without using the object's method function. The affected
4651 files: lib/silccrypt/silccipher.[ch].
4653 * Implemented silc silc_client_add_private_message_key,
4654 silc_client_add_private_message_key_ske,
4655 silc_client_del_private_message_key,
4656 silc_client_list_private_message_keys and
4657 silc_client_free_private_message_keys functions in the
4660 Added functions silc_client_send_private_message_key to send
4661 the Private Message Key payload and silc_client_private_message_key
4662 to handle incoming Private Message Key payload.
4664 * Added Cipher field to the Private Message Key payload to set
4665 the cipher to be used. If ignored, the default cipher defined
4666 in the SILC protocol (aes-256-cbc) is used.
4668 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Removed lib/silcclient/ops.h file.
4672 Redefined parts of the SILC Client Library API. Created new
4673 file silcapi.h that deprecates the ops.h file and defines the
4674 published Client Library API. Defined also private message key
4675 API and channel private key API into the file.
4677 This is the file that the application must include from the
4678 SILC Client Library. Other files need not be included by
4679 the application anymore.
4681 * Added new key_agreement client operation callback and also
4682 defined the Key Agreement library API for the application.
4684 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4687 is used by clients to request key negotiation between another
4688 client in the SILC network. If the negotiation is started it
4689 is performed using the SKE protocol. The result of the
4690 negotiation, the secret key material, can be used for example
4691 as private message key.
4693 Implemented the Key Agreement payload into the files
4694 lib/silccore/silauth.[ch].
4696 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Redefined ciphers for the SILC protocol. Added some new ciphers
4699 and defined the key lengths for the algorithms. Changed the
4700 code accordingly. The default key length is now 256 bits.
4702 * Fixed SKE key distribution function silc_ske_process_key_material
4703 when the key length is more than 128 bits. The default key
4704 length in SILC is now 256 bits.
4706 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4707 to indicate unsupported algorithm.
4709 * Renamed rijndael.c to aes.c and all functions as well.
4711 * Fixed a long standing channel key setting bug in client library.
4712 Weird that it has never surfaced before.
4714 * Fixed bug in channel deletion. If the entire channel is removed
4715 then it must also delete the references of the channel entry
4716 from the client's channel list as the client's channel entry and
4717 the channel's client entry share same memory.
4719 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * Implemented CONNECT and SHUTDOWN commands in the client.
4723 * Implemented CLOSE command to the client.
4725 * Added the function silc_idlist_find_server_by_name into the
4726 files silcd/idlist.[ch].
4728 Added the function silc_idlist_find_server_by_conn into the
4729 files silcd/idlist.[ch].
4731 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4733 * DIE command was renamed to SHUTDOWN. Updated the both code
4736 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4737 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4739 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4742 * Added function silc_server_create_connection function to create
4743 connection to remote router. My server implementation actually
4744 does not allow router to connect to normal server (it expects
4745 that normal server always initiates the connection to the router)
4746 so the CONNECT command is only good for connecting to another
4749 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4752 or some other client was kicked from the channel.
4754 Implemented the handling of the notify type to both client
4757 Implemented silc_server_send_notify_kicked to send the KICKED
4758 notify. It is used to send it to the server's primary router.
4760 * Implemented the KICK command into server and client.
4762 * Added `query' argument to the silc_idlist_get_client function
4763 to indicate whether to query the client from server or not if
4766 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4767 to indicate that the client is not channel founder.
4771 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Removed the rng context from SilcPacketContext structure and
4774 changed that the packet routine uses the Global RNG API.
4776 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Added support for quit message that client can "leave" on the
4779 channel when it quits the SILC. It is ditributed inside the
4780 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4782 Added silc_server_free_client_data that will take the
4783 signoff message as argument.
4785 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4787 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Updated parts of the protocol specification to keep it up
4792 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4795 payloads in one packet.
4797 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4798 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4799 use now the new List flag.
4801 * Also deprecated the following packet types: REPLACE_ID,
4802 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4804 * Added list support for Notify packet in server.
4806 * Added silc_server_send_notify_channel_change to send the
4807 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4808 the silc_server_send_replace_id.
4810 * Added silc_server_send_notify_nick_change to send the
4811 NICK_CHANGE notify type. Deprecates the function
4812 silc_server_send_replace_id.
4814 * Added silc_server_send_notify_join to send the JOIN notify type.
4815 Deprecates the function silc_server_send_new_channel_user.
4817 * Added silc_server_send_notify_leave to send LEAVE notify type.
4818 Deprecates the function silc_server_send_remove_channel_user.
4820 * Added silc_server_send_notify_cmode and
4821 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4822 types. Deprecates the silc_server_send_set_mode function.
4824 * Added SERVER_SIGNOFF notify type to indicate that server has
4825 quit. This means that all clients on the channel from that
4826 server will drop. This can be also used when netsplit happens.
4828 Deprecated REMOVE_ID packet type since it is not needed anymore
4831 Added silc_server_send_notify_server_signoff to send the
4832 SERVER_SIGNOFF notify type. Deprecates the function
4833 silc_server_send_remove_id.
4835 Added also silc_server_send_notify_signoff to send the
4836 SIGNOFF notify type.
4838 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4839 SILC protocol from this day on. Changed the protocol
4840 specification as well.
4842 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4843 notify type. It is used between routers to notify about
4844 topic changes on a channel.
4846 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4849 * Partly updated the protocol specification to comply with the
4850 changes now made. It is still though a bit outdated.
4852 * The JOIN notify type now takes one extra argument <Channel ID>.
4853 The packet used to be destined to the channel but now the
4854 JOIN type may be sent as list thus it is impossible to
4855 destine it to any specific channel. By adding this argument
4856 it is again possible.
4858 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4860 * Added CREDITS file. The CHANGES and CREDITS file will appear
4861 in the distribution as well.
4863 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4866 types in the server's silcd/packet_receive.c.
4868 * Implemented CMODE and CUMODE to work in router environment.
4870 * Fixed minor encoding and decoding buglet from the
4871 lib/silccore/silcmode.c.
4873 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4876 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4878 * Changed all SilcConfigServer* and silc_config_server* to
4879 SilcServerConfig* and silc_server_config*, respectively.
4882 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Associated the ID (client or server ID) to the Authentication
4885 Payload to avoid any possibility of forging. Updated the
4886 protocol specification and the code accordingly.
4888 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * The RSA key length is now save to the RsaKey context in the
4891 key generation process in lib/silccrypt/rsa.c. The key length
4892 is now used to figure out the maximum size of the block allowed
4893 to be encrypted/signed.
4895 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4896 is equivalent to the silc_mp_mp2bin but does not allocate any
4899 * Changed silc_mp_mp2bin API to take length argument. If it is
4900 non-zero then the buffer is allocated that large. If zero, then
4901 the size is approximated using silc_mp_sizeinbase, which however
4904 * Created Global RNG API which is global RNG that application can
4905 initialize. After initializing, any routine anywhere in the
4906 code (including library) can use RNG without allocating a new
4907 RNG object. This was done to allow this sort of use of the
4908 RNG in code that has no chance to allocate RNG object. All
4909 applications currently allocate this and many routines in the
4910 library use this. Affected file lib/silccrypt/silcrng.[ch].
4912 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4913 it to use the Global RNG API.
4915 * Defined Authentication Payload into protocol specification that
4916 is used during SILC session to authenticate entities. It is
4917 used for example by client to authenticate itself to the server
4918 to obtain server operator privileges.
4920 Implemented this payload into the lib/silccore/silcauth.[ch].
4921 Implemented also routines for public key based authentication
4922 as the new protocol specification dictates.
4924 Moved definitions of different authentication methods from
4925 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4927 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4928 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4929 silc_pkcs_verify_with_hash functions into the file
4930 lib/silccrypt/silcpkcs.[ch].
4932 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * The client entry's userinfo pointer must be always valid.
4935 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4936 will fail since it requires the userinfo. Now, the userinfo
4937 is allocated as "" if actual userinfo does not exist. Actually,
4938 it must exist and it is totally Ok to drop client connections
4939 that does not announce the userinfo. However, we will make
4940 this workaround for now.
4942 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4943 to return the remote port by socket.
4945 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4948 SILC_SERVER_PENDING_EXEC and added an new macro
4949 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4950 data or when error occurs while processing the pending command.
4952 Added new argument `destructor' into silc_server_command_pending
4953 and to the SilcServerCommandPending object. This destructor is
4954 now called after calling the pending callback or if error occurs
4955 immediately. If error occurs the actual pending callback won't
4956 be called at all - only the destructor. The destructor may be
4957 NULL if destructor is not needed.
4959 All this applies for client library code as well. Similar
4960 changes were made there as well for the pending commands.
4962 In the client, the application must now allocate the
4963 SilcClientCommandContext with the silc_client_command_alloc
4966 * Added reference counter to the SilcServerCommandContext. Added
4967 function silc_server_command_alloc and silc_server_command_dup
4970 Same type of functions added to the client library for the same
4973 * Removed the cmd_ident from IDListData away since it is now
4974 global for all connections. It is the command identifier used
4975 in command sending and with pending commands. The affected file
4978 * Added reference counter to the SilcSocketConnection objecet to
4979 indicate the usage count of the object. The object won't be
4980 freed untill the reference counter hits zero. Currently only
4981 server uses this, and client ignores it. The client must be
4982 set to use this too later. The affected files are
4983 lib/silccore/silcsockconn.[ch]. Added also the function
4984 silc_socket_dup to increase the reference counter.
4986 This was mainly added because it is possible that the socket
4987 is removed underneath of pending command or other async
4988 operation. Now it won't be free'd and proper DISCONNECTING
4989 flags, etc. can be set to avoid sending data to connection that
4990 is not valid anymore.
4992 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4993 the connection. After that it sets SILC_SET_DISCONNECTED.
4994 It is, however, possible that the socket data is not still freed.
4995 The silc_server_packet_process now checks that data is not
4996 read or written to connection that is DISCONNECTED. The socket
4997 get's freed when the reference counter hits zero.
4999 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Changed the client operation API: channel_message operation's
5002 `sender' is now the client entry of the sender, not the nickname
5003 and the `channel' is the channel entry, not the channel name.
5005 In the private_message operation the `sender' is now also the
5006 client entry of the sender not the nickname.
5008 Affected file is lib/silcclient/ops.h and all applications
5009 using the client operations.
5011 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5013 * Moved the calling of ops->connect() from connect_to_server_final
5014 into receive_new_id functin since that is the point when the
5015 client is actually allowed to send traffic to network. The
5016 affected file is lib/silcclient/client.c.
5018 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5021 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5022 (if needs broadcasting) instead of broadcasting the packets one
5023 by one which would make a burst in the network traffic.
5025 * Added `broadcast' argument to the functions in silcd/server.[ch]
5026 silc_server_create_new_channel[_with_id] to indicate whether
5027 to send New Channel packet to primary router.
5029 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Added new function into the silcd/server.[ch] files:
5032 silc_server_create_new_channel_with_id to create new channel with
5033 already existing Channel ID.
5035 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5036 lib/silccore/silcpacket.h. This packet is used t send list of
5037 Set Mode payloads inside one packet. Server uses this to set
5038 the modes for the channels and clients on those channels, that it
5039 announced to the router when it connected to it. The protocol
5040 specification has been updated accordingly.
5042 * The silc_server_new_channel did not handle the packet coming
5043 from normal server as it normally does not send that. However,
5044 when it announces its channels it does send it. Implemented
5045 the support for that.
5047 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5048 into the file lib/silccore/id.h.
5050 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Fixed memory leaks in the functions silc_idlist_del_client,
5053 silc_idlist_del_channel and silc_idlist_del_server in the file
5054 silcd/idlist.c. All of those leaked like a sieve.
5056 * Fixed some small memory leaks in the client's function
5057 silc_client_notify_by_server.
5059 * Added functions into silcd/server.c: silc_server_announce_clients,
5060 silc_server_announce_channels and silc_server_announce_server.
5061 These functions are used by normal and router server to announce
5062 to its primary router about clients, channels and servers (when
5063 router) that we own. This is done after we've connected to the
5066 These functions effectively implements the following packet types:
5067 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5068 and SILC_PACKET_NEW_ID_LIST.
5070 * Added new functions into the silcd/packet_receive.[ch]:
5071 silc_server_new_id_list, silc_server_new_channel_list and
5072 silc_server_new_channel_user_list to handle the incoming
5073 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5075 * Added support of changing Channel ID in the function
5076 silc_server_replace_id. If the server that announces a channel
5077 to the router already exists in the router (with same name but
5078 with different Channel ID), router is responsible to send
5079 Replace ID packet to the server and force the server to change
5080 the Channel ID to the one router has.
5082 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5083 client that the Channel ID has been changed by the router. The
5084 normal server sends this to the client. Client must start using
5085 the new Channel ID as the channel's ID.
5087 Implemented handling of this new type into lib/silcclient/client.c
5088 into the function silc_client_notify_by_server.
5090 * Added new function silc_idlist_replace_channel_id into the files
5091 silcd/idlist.[ch] to replace the Channel ID.
5093 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Call silc_server_command_identify_check always when processing
5096 the IDENTIFY command in silcd/command.c
5098 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5101 send keepalive packets. The packet can be sent by clients,
5102 servers and routers.
5104 Added function silc_socket_set_heartbeat into the file
5105 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5106 If not set, the heartbeat is not performed. The actual
5107 heartbeat is implemented in the low level socket connection
5108 library. However, application is responsible of actually
5111 Added silc_server_send_heartbeat to send the actual heartbeat
5112 packet into silcd/packet_send.[ch]. Server now performs
5113 keepalive with all connections.
5115 * Added silc_task_get_first function into lib/silcutil/silctask.c
5116 to return the timeout task with shortest timeout. There was a bug
5117 in task unregistration that caused problems. TODO has been
5118 updated to include that task system must be rewritten.
5120 * The client library will now resolve the client information when
5121 receiving JOIN notify from server for client that we know but
5122 have incomplete information.
5124 * Rewrote parts of silc_server_remove_from_channels and
5125 silc_server_remove_from_one_channel as they did not remove the
5126 channel in some circumstances even though they should've.
5128 * Encryption problem encountered in server:
5130 The LEAVE command used to send the Channel Key packet to the
5131 router immediately after generating it. However, the code
5132 had earlier sent Remove Channel user packet but not immediately,
5133 ie. it was put to queue. The order of packets in the router
5134 was that Channel Key packet was first and Remove Channel User
5135 packet was second, even though they were encrypted in the
5136 reverse order. For this reason, MAC check failed. Now, this
5137 is fixed by not sending the Channel Key packet immediately but
5138 putting it to queue. However, this is more fundamental problem:
5139 packets that are in queue should actually not be encrypted
5140 because packets that are sent immediately gets encrypted
5141 actually with wrong IV (and thus MAC check fails). So, packets
5142 that are in queue should be encrypted when they are sent to
5143 the wire and not when they put to the queue.
5145 However, the problem is that the current system has not been
5146 designed to work that way. Instead, the packet is encrypted
5147 as soon as possible and left to the queue. The queue is then
5148 just purged into wire. There won't be any fixes for this
5149 any time soon. So, the current semantic for packet sending
5152 o If you send packet to remote host and do not force the send
5153 (the packet will be in queue) then all subsequent packets to the
5154 same remote host must also be put to the queue. Only after the
5155 queue has been purged is it safe again to force the packet
5158 o If you send all packets immediately then it safe to send
5159 any of subsequent packets through the queue, however, after
5160 the first packet is put to queue then any subsequent packets
5161 must also be put to the queue.
5163 Follow these rules and everything works fine.
5165 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Added new function silc_server_remove_clients_by_server to
5168 remove all client entries from ID list when the server connection
5169 is lost. In this case it is also important to invalidate all
5170 client entires as they hold the invalid server entry. This
5171 fixes fatal bug when server has lost connection and will reconnect
5174 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Made some sanity checks to silc_server_daemonise like to check
5177 whether the requested user and group actually exists.
5179 * Added sanity check to SKE's silc_ske_responder_finish to check
5180 that the public and private key actually is valid.
5182 * Invalidate the client's nickname when receiving Replace ID
5183 packet and the Client ID is being replaced. This means that the
5184 server will query the nickname if someone needs it (client)
5187 * Sort the ID Cache in client library when the ID Cache data
5188 has changed (needs sorting).
5190 * Do not allow for SILC client to create several connections to
5191 several servers. The client does not support windows right now
5192 and generating multiple connections causes weird behaviour.
5194 Irssi-silc client does support windows and can handle several
5195 connections without problems, see: www.irssi.org and SILC plugin.
5197 * Fixed some places where client was added to the IDList. The
5198 rule of thumb is following (in order to get everything right):
5199 If the client is directly connected local client then the
5200 `connection' argument must be set and `router' argument must be
5201 NULL to silc_idlist_add_client function. If the client is not
5202 directly connected client then the `router' argument must
5203 bet set and the `connection' argument must be NULL to the
5204 silc_idlist_add_client function.
5206 * The funtion silc_server_packet_send_local_channel actually did
5207 not check whether the client was locally connected or not. It
5208 does that now. Fixed a bug related to LEAVE command.
5210 * Fixed Remove Channel User payload parsing bug in server's
5211 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5213 * The server's silc_server_save_channel_key now checks also the
5214 global ID list for the channel as it might not be in the local
5215 list. Fixed a bug related to LEAVE command.
5217 * Is this the end of the [<unknown>] buglet that has been lurking
5218 around for a long time? A little for loop fix in server's
5219 silc_server_command_whois_parse that is used by both IDENTIFY
5220 and WHOIS command. At least, this was a clear bug and a cause
5221 of one type of [<unknown>] buglet.
5223 * WHOIS and IDENTIFY commands call the function
5224 silc_server_command_[whois/identify]_check function even if
5225 we are not router server.
5227 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Added --with-gmp configuration option. If set the GMP
5230 is always compiled in the SILC source tree. If not set then
5231 it is checked whether the system has the GMP3 installed. If
5232 it has then the GMP won't be compiled (the system's headers
5233 and library is used), if it doesn't have it then the GMP is
5234 compiled in the SILC source tree.
5236 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Changed RSA private exponent generation to what PKCS #1
5239 suggests. We try to find the smallest possible d by doing
5240 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5241 not security fix but optimization.
5243 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Added new config entry [Identity] to fork the server and run
5246 it as specific user and group. A patch from Bostik.
5248 * Imported Dotconf configuration library into lib/dotconf.
5249 This will be used to create the SILC configuration files later.
5250 It will appear in the distsribution after this commit.
5252 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * A big code auditing weekend happening. Auditing code for
5255 obvious mistakes, bugs and errors. Also, removing any code
5258 Removed files for being obsolete:
5260 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5261 inline in the file lib/silcutil/silcbuffer.h)
5263 o lib/silcutil/silcbufutil.c (the header has inline versions)
5265 Changed code to fix possible error conditions:
5267 o The buffer formatting routines now check that the destination
5268 buffer really has enough space to add the data. This applies for
5269 both buffer formatting and unformatting
5270 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5271 unformatting was changed to accomodate following rules:
5272 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5273 sent to the function while XXX_*STRING will not allocate or copy
5274 the data into the buffer. Instead it sets the pointer from the
5275 buffer into the pointer sent as argument (XXX_*STRING used to
5276 require that the pointer must be allocated already). This change
5277 makes this whole thing a bit more consistent and more optimized
5278 (note that the data returned in the unformatting with XXX_*STRING
5279 must not be freed now). The routines return now -1 on error.
5281 o Tried to find all code that use buffer_format and buffer_unformat
5282 and added return value checking to prevent formatting and
5283 especially unformatting errors and possible subsequent fatal
5286 o Changed ske->x and ske->KEY to mallocated pointers in
5287 lib/silcske/silcske.h. Fixed possible data and memory leak.
5289 o Added return value checking to all *_parse* functions. Fixed
5290 many memory leaks as well.
5292 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5293 so that buffer overflows would not happen. All code now also
5294 checks the return value as it can fail.
5296 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Added reconnection support to server if the normal server looses
5299 its connection to the router (for example if router is rebooted).
5300 The server performs normal reconnection strategy implemented
5301 to the server. Affected file silcd/server.c.
5303 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Added new packet type SILC_PACKET_SET_MODE that is used to
5306 distribute the information about changed modes (for clients,
5307 channels and clients channel modes) to all routers in the
5308 network. Updated the protocol specification accordingly.
5310 Added functions into silcd/packet_send.c and
5311 silcd/packet_receive.c: silc_server_send_set_mode,
5312 silc_server_set_mode.
5314 Added new files silcmode.[ch] into lib/silccore that implements
5315 the encoding and decoding of Set Mode Payload. Added new type
5316 SilcSetModePayload. Moved the definitions of different modes
5317 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5319 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Oops, a little mistake in server's connection authentication
5322 protocol. The protocol is not ended with FAILURE but with
5323 SUCCESS if the authentication is Ok. :) Affected file is
5326 * Implemented NICK_CHANGE notify handling in server in the file
5327 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5328 the local clients on the channel. After the changing nickname
5329 in router environment snhould work and the [<unknown>] nickname
5330 should appear no more.
5332 The silc_server_replace_id function that receives the Replace ID
5333 payload now sends the NICK_CHANGE notify type also in the file
5334 silcd/packet_receive.c
5336 * Changed WHOIS and IDENTIFY command to support the maximum amount
5337 of arguments defined in protocol specs (3328 arguments). This
5338 fixed a bug that caused problems when there were more than three
5341 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Added extra parameter, command identifier, to the
5344 silc_client_send_command so that explicit command identifier
5347 Changed that ID list routines uses specific command identifier
5348 when sending WHOIS/IDENTIFY requests to the server so that they
5349 can be identified when the reply comes back.
5351 Affected files lib/silcclient/command.[ch],
5352 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5354 * Added `sender' argument to silc_server_packet_send_to_channel
5355 to indicaet the sender who originally sent the packet to us
5356 that we are now re-sending. Ignored if NULL. Affected file
5357 silcd/packet_send.[ch].
5359 * Added some server statistics support in silcd/server_internal.h
5360 SilcServerStatistics structure and around the server code. Also
5361 send some nice statistics information when client is connecting
5364 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * Fixed channel ID decoding in server's JOIN command reply in
5367 silcd/command_reply.c
5369 * Fixed braodcasting of replace ID payload to not to send it if
5370 we are standalone server in silcd/packet_receive.c.
5372 * Fixed all channel message sending routines to not to send
5373 packets to clients that has router set, since they are routed
5374 separately in the same function earlier. Affects file
5375 silcd/packet_send.c and all channel packet sending functions.
5377 * In USERS reply, res_argv[i] are not allocated, the table
5378 is allocated. Thus changed that free the table, not its
5381 * In server's whois_check and identify_check if the client is
5382 locally connected do not send any WHOIS commands - they are not
5385 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Fixed some minor bugs in client when sending WHOIS command. The
5388 arguments was in wrong order.
5390 * Removed statis function add_to_channel from server in
5391 silcd/command.c that was previously used with the joining but
5394 * Tested USERS command in router environment successfully with two
5395 routers, two servers and two clients.
5397 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5399 * Reorganized the USERS command and command reply in client library
5400 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5401 When the command is given by user we register a pending command
5402 callback that will reprocess the command after the reply has been
5403 received from the server. When reprocessing the packet we then
5404 display the information. Thus, the USERS information is displayed
5405 now in the command callback instead of in the command reply
5406 callback. The processing of the command is same as previously
5407 when server has sent the command reply in the JOINing process.
5409 * Added to USERS command in silcd/command_reply.c to join the client,
5410 we didn't use to know about, to the channel after we've created
5411 a client entry for it. Also, for clienet we did know already still
5412 check whether it is on the channel or not and add it if not.
5414 * Removed silc_server_command_join_notify as the function and its
5417 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Changed the client's pending command handling to the same as the
5420 server's pending command handling. It is also now possible to
5421 execute command reply functions from other command reply
5422 function as the function callbacks for commands and command
5423 replies are one and same. The pending commands are not static
5424 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5425 in client connection context. Thus, pending commands are server
5426 connection specific as it is convenient.
5428 Changed the function silc_client_command_pending and
5429 silc_client_command_pending_del and added new function
5430 silc_client_command_pending_check. Removed the
5431 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5434 * Added cmd_ident, current command identifier, to the client
5435 connection context in lib/silcclient/client.h to keep track on
5436 command identifiers used in command sending. Client's command reply
5437 function handling now supports the mandatory command identifiers.
5439 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5440 funtions in client to fully support pending command callbacks.
5442 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5443 as one of the arguments to the application in the command reply
5446 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5447 before first releasing SILC but came back. Now it is removed again
5448 and should come back nomore. The FORWARDED flag was used only
5449 by the JOINing procedure by forwarding the command packet to router.
5450 Now, the JOINing procedure has been changed to more generic (due
5451 to various router environment issues) and FORWARDED is not needed
5452 anymore for anything. The protocol specification is yet to be
5455 Now, removed silc_server_packet_forward from server and the flag
5456 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5458 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Renamed NAMES command to USERS command. The NAMES was named that
5461 due to historical reasons. Now it is renamed. Also, rewrote
5462 parts of the USERS command. The nickname list is not sent anymore
5463 by the server. Only Client ID and mode lists are sent in the USERS
5464 command. Changed this also to the protocol specification.
5466 The client now resolves the names and stuff after it receives
5467 the USERS list from the server when joining to the channel.
5469 * WHOIS and IDENTIFY commands has been changed to support multiple
5470 Client ID's per command. One can now search for multiple users
5471 in the network by sending only one WHOIS or IDENTIFY command.
5472 Changed the code and the protocol specifications.
5474 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5475 uses silc_server_command_whois_parse to parse the request. */
5477 * If normal server, do not parse the WHOIS and IDENTIFY requests
5478 before sending it to the router. Saves some time.
5480 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Fixed JOIN command on client library. Wrong number of arguments
5483 used to crash the client.
5485 * Added silc_server_channel_has_global function to check whether
5486 channel has global users or not.
5488 * Added silc_server_channel_has_local function to check whether channel
5489 has locally connected clients on the channel.
5491 * The silc_server_remove_from_one_channel now checks whether the
5492 channel has global users or not after given client was removed from
5493 the channel. It also checks whether the channel has local clients
5494 on the channel anymore. If it does not have then the channel entry
5495 is removed as it is not needed anymore.
5497 * The silc_server_notify now checks on JOIN notify whether the joining
5498 client is one of locally connected or global. If it is global then
5499 the channel has now global users on the channel and that is marked
5500 to the channel entry. Also, it now saves the global client to
5501 global list who is joining and JOINs it to the channel. This is
5502 for normal server, that is.
5504 Changed silc_server_send_notify_on_channel,
5505 silc_server_packet_relay_to_channel and
5506 silc_server_packet_send_to_channel check if we are normal server
5507 and client has router set (ie. global client) do not send the
5508 message to that client, as it is already routed to our router.
5510 * Implemented LEAVE notify type handling in silc_server_notify
5513 * Tested LEAVE command in router environment successfully. Tested
5514 with two routers, two servers and two clients.
5518 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5520 * Implemented SIGNOFF notify type handling in silc_server_notify
5523 * silc_server_remove_id now removes the client entry from all channels
5524 it has joined and thusly sends SIGNOFF notify type.
5526 * Rewrote the NAMES list generation in server by removing two excess
5527 loops. The lists are created now inside one loop.
5529 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * silc_server_remove_channel_user checks now also global list
5532 for channel and client.
5534 * silc_server_new_channel_user checks now both local and global
5535 list for channel and client. Fixed a bug in client id decoding.
5536 Used to decode wrong buffer.
5538 * silc_server_channel_message checks now both local and global
5539 list for channel entry.
5541 * Tested channel joining (hence JOIN) in router environment
5542 successfully. Tested with two routers, two servers and two
5545 * Tested channel message sending in router environment successfully.
5547 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Added silc_server_save_channel_key into server.[ch] to save the
5550 received channel key in Channel Key payload processing. It is
5551 also used in JOIN command reply handling.
5553 Equivalent function silc_client_save_channel_key added into
5554 client.[ch] into client library.
5556 * Changed JOIN command reply to send information whether the channel
5557 was created or not (is existing already) and the channel key
5558 payload. Changed protocol specs accordingly.
5560 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5561 the request was sent by ID and not by nickname. Crashed on
5564 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5567 now correctly save the received data.
5569 * silc_server_free_sock_user_data now notifies routers in the
5570 network about entities leaving the network.
5572 At the same time implemented functions silc_server_remove_id
5573 and silc_server_send_remove_id to receive and send REMOVE_ID
5574 packets. The packet is used to notify routers in the network
5575 about leaving entities. The ID removed will become invalid in
5578 * Added function silc_idlist_del_server into server. Removes and
5579 free's server entry from ID list.
5581 * silc_server_private_message function now checks, if we are router,
5582 that the destination ID really is valid ID, naturally.
5584 * In router when NEW_ID packet is received (for new client) the
5585 hash of the Client ID is saved in the ID Cache but the
5586 client->nickname is set to NULL, instead of putting the hash
5589 IDENTIFY command now also checks that client->nickname must be
5590 valid. If it is not if will request the data from the server who
5591 owns the client. Added new function
5592 silc_server_command_identify_check.
5594 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5595 to set the command to already allocated Command Payload.
5597 * Tested private message sending in router environment with two
5598 routers, two servers and two clients. Fixed minor bugs and now
5601 * Fixed segfault from client's NAMES command. Used to crash if
5604 * Forwarded packets must not be routed even if it is not destined
5605 to the receiver. Changed server code comply with this.
5607 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Added `require_reverse_mapping' boolean value to ServerParams
5610 structure. If TRUE (not default) the server will require that
5611 the connecting host has fully qualified domain name.
5613 If the reverse mapping is not required and hostname could not be
5614 found the IP address is used as hostname.
5616 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Implemented version string checking to both client and server.
5619 The check is incomplete currently due to the abnormal version
5620 strings used in development version of SILC.
5622 * Changed all command functions in server to use the new
5625 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * Changed char *data to unsigned char *data in ID Cache system to
5628 support binary data as ID Cache data. Changed code to support
5629 binary data in lib/silccore/idcache.c.
5631 * Renamed silc_server_packet_relay_command_reply to
5632 silc_server_command_reply as it is normal packet receiving
5633 function. Rewrote the function to accept command replys for
5634 servers and not only for clients.
5636 * Mark remote router always as registered server if we are connecting
5637 to it. Otherwise, commands sent by the router to us are ignored.
5639 * All ID List find routines now returns the ID Cache Entry pointer
5640 as well if requested.
5642 * WHOIS command works now in router environment, tested with two
5643 routers, two servers and two clients.
5645 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5646 in router environment (as it is almost equivalent to WHOIS) but
5647 hasn't been tested thoroughly. Added new functions:
5649 silc_server_command_identify_parse
5650 silc_server_command_identify_send_reply
5651 silc_server_command_identify_from_client
5652 silc_server_command_identify_from_server
5654 * Disabled route cache adding because adding two different ID's with
5655 same IP replaces the old cache entry thus giving wrong route.
5656 The entry->router->connection is always the fastest route anyway
5657 so route cache may not be needed. Of course, new routes maybe
5658 established after receiving the ID when the entry->router->connection
5659 might not be anymore the most optimal.
5661 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5663 * Add route cache for received ID for fast routing.
5665 * Added silc_server_packet_route to route received packet on router
5666 that is not destined to us.
5668 * Renamed silc_server_get_route to silc_server_route_get.
5670 * Added id_string and id_string_len fields into SilcServer to
5671 include encoded ServerID for fast comparing without excess
5672 encoding of the ID's.
5674 * Cleaned up WHOIS command on server side. Added following static
5677 silc_server_command_whois_parse
5678 silc_server_command_whois_check
5679 silc_server_command_whois_send_reply
5680 silc_server_command_whois_from_client
5681 silc_server_command_whois_from_server
5683 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5684 arguments in command replies. All command functions should be
5685 updated to use this macro.
5687 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5689 * Minor typo fixes on command reply handling on server.
5691 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Added silc_server_command_add_to_channel internal routine to add
5694 the client to the channel after router has created the channel and
5695 sent command reply to the server.
5697 * Added generic silc_server_send_command to send any command from
5700 * Use static buffer with ID rendering instead of duplicating data.
5702 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Fixed a channel user mode bug when joining to a channel server gave
5705 everybody channel founder rights, oops.
5707 * We mark ourselves as the router of the incoming server connection
5708 if we are router ourselves. This way we can check in some packet
5709 sending functions whether it is locally connected server. For
5710 incoming router connections we put NULL.
5712 * For router sending packets locally means now always sending the
5713 packet cell wide; to local clients and local servers. For normal
5714 server sending packet locally means sending it to only local
5717 * Fixed the JOIN command to really work in router environment. If the
5718 channel is created it is always created by the router. Router is
5719 also responsible of making the initial joining to the channel,
5720 sending JOIN notify to the sending server and distributing
5721 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5722 does not exist server doesn't do anything else but forward the
5723 command to the router which performs everything.
5725 * Added silc_server_send_channel_key function to send the Channel Key
5728 * Added silc_server_create_channel_key to create new channel key. The
5729 channel key is now re-generated everytime someone joins or leaves
5730 a channel, as protocol dictates. Note: channel->key_len is the
5733 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5736 packet_receive.[ch] to separate packet sending and receiving
5737 routines. The server.[ch] now includes everything else including
5738 actual packet processing (writing and reading data) and other
5741 Renamed silc_server_private_message_send_internal to
5742 silc_server_send_private_message. The routine is still though
5743 used only to relay private messages as server does not send
5744 private messages itself.
5746 Renamed silc_server_new_channel to silc_server_create_new_channel
5747 and added new function sicl_server_new_channel that handles the
5748 incoming New Channel packet. Added also new sending function
5749 silc_server_send_new_channel to send New Channel Payload.
5751 * Added new function silc_server_notify to process incoming notify
5752 packet to the server/router. Server may then relay the notify
5753 to clients if needed.
5755 * Added new function silc_server_new_channel_user to process incoming
5756 New Channel User packet. Router will redistribute the packet and
5757 send JOIN notify to its local clients and locally connected servers
5758 if needed. Normal server will send JOIN notify to its local client
5759 on same channel when received this packet. Added also corresponding
5760 sending function silc_server_send_new_channel_user to sent the
5763 * Added boolean route argument to send_notif_to_channel and
5764 packet_send_to_channel functions to attempt to route the packet
5765 if it is TRUE and send only locally if it is FALSE.
5767 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * silc_server_replace_id now broadcasts the received replace ID
5770 packet if it is not broadcast packet already. The router must
5771 broadcast to inform other routers about changed ID.
5773 * Added backpointer to server's router into SilcServer context in
5774 silcd/server_internal.h.
5776 * Fixed silc_server_packet_broadcast to send correct broadcast
5779 * The channel key is now distributed to the local client as soon
5780 as it is received from the router (in router environment) so that
5781 no other packet may be sent for the channel until client has
5784 * silc_server_remove_channel_user now broadcasts the received
5785 Remove Channel User packet if it is not broadcast packet already.
5786 The router must broadcast to inform other routers about removed
5789 * Added users field into SilcPacketContext that is a reference count
5790 of the context. One can increase the reference count by calling
5791 silc_packet_context_dup which is now changed to just increase the
5792 reference count instead of duplicating the data. The reference
5793 count is decresed by calling silc_packet_context_free that will
5794 free the data after the reference count hits zero.
5796 For now on the packet context and everything allocated into it
5797 (including the raw packet from network) must be freed by calling
5798 the new silc_packet_context_free function. Added also new function
5799 silc_packet_context_alloc that must be used now to allocate the
5800 context. This also means that if a routine is asynchronous from
5801 silc_[client/server]_packet_parse_type the packet context must
5802 be duplicated by calling silc_packet_context_dup. Otherwise it
5803 gets free'd after silc_[client/server]_packet_parse_type returns.
5804 Also, one must remember that if packet is duplicated then its
5805 reference count must be decresed by calling the free function as
5806 many times as it was duplicated.
5808 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5809 from both client and server.
5811 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Made joining to a channel working in router environment.
5815 * Cleaned up JOIN command on server side and create function
5816 silc_server_command_join_channel internal routine to make the
5819 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Changed silc_command_pending list to SilcDList. Also, added
5822 `ident' field to SilcServerCommandPending structure to identify
5823 the reply and to call correct callback.
5825 Added silc_server_command_pending_check function to replace the
5826 corresnponding macro. The silc_command_pending list is not
5829 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5830 to set identifier to previously allocated Command Payload. It
5831 is used to set identifier for command when resending Command
5834 * Added silc_command_payload_encode_payload to encode Command
5835 Payload buffer from SilcCommandPayload structure.
5837 * Added silc_argument_payload_encode_payload to encode Argument
5838 payload buffer from SilcArgumentPayload structure.
5840 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Changed WHOIS command to support router connection on server side.
5843 The whois request is always sent to router unless the server is
5844 standalone server. After server has received the reply from the
5845 router will it send the reply to the client.
5847 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5848 broadcast received broadcast packet. The function is used only
5849 by router. The broadcast packet is always sent to the router's
5852 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5853 render given ID to printable string, for log files for example.
5855 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Made basic router to router connections working. At least they
5858 can now connect to each other but nothing really works the way
5859 they are supposed - yet.
5861 * Added new initiator token to RouterConnection configuration
5862 file in silcd/serverconfig.[ch]. It is used to tell whether we
5863 are the initiator to the remote router or whether we'll expect
5864 the other end to connect.
5866 * Moved registering of listener task to silc_server_init, hence
5867 the server starts listenning as soon as it is run, even if it
5868 does not have connections to other routers. Let's see how well
5871 * Changed default connection retry timeouts for more suitable in
5874 * Removed cipher and such arguments from silc_idlist_add_client
5875 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5876 Added new function silc_idlist_add_data to add the keys and stuff
5879 * Added SilcIDListData structure and added it to SilcClientEntry
5880 and SilcServerEntry as their first field in the structure. This
5881 way we can explicitly cast the ID entries to the SilcIDListData
5882 structure and get common data for the entries. In past, we had
5883 to first check what type of connection it is and then cast it to
5884 correct ID entry type. Now, we can directly cast the opaque
5885 pointer to the SilcIDListData (no matter what ID entry it actually
5886 is) and get the data needed.
5888 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5891 in some circumstances even if threre were timeout tasks, though not
5892 IO tasks, but tasks anyway. Now fixed.
5894 * Defined SilcServerConnection structure to hold connection specific
5895 stuff about directly connected servers and routers. The definition
5896 is currently in silcd/server_internal.h. I thought about having
5897 a bit more important role fro this struct but for now it is used
5898 only when connecting to other server (or router actually).
5900 * Added connecting retry support in server when connecting to
5901 router(s). The retry feature implement exponential backoff
5902 algorithm. Also, added SilcServerParams structure to hold default
5903 parameters for server. For now, it include these retry settings
5904 and are hard coded. After server is moded to be as Silc Server
5905 Library this structure will be more important.
5907 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Changed client librarys channel->clients table to SilcList and
5910 changed code accordingly.
5912 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Changed client's channel table to SilcList and changed code
5915 accordingly. Also changed SilcChannelClientEntry to include back-
5916 pointer to the channel so that client entry can use that structure
5917 as list as well and we have fast cross-reference to the channel.
5918 This change dramatically decreased the complexity of channel
5919 handling with client entry and vice versa (removed one extra
5920 loop when searching for channel entry from many functions).
5922 * Changed server->sim from table to SilcDList and changed code
5925 * NAMES command can now be used from user interface. It will show
5926 the user list on the channel, neatly.
5928 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5929 Code now saves realname of the user if it becomes available.
5931 * Renamed configure.in to configure.in.pre and made ./prepare
5932 script to automatically add correct version string to
5933 configure.in which it creates from configure.in.pre.
5935 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * NAMES command reply now shows users mode with the nickname when
5940 * Moved silc_client_ch[u]mode[_char] functions from
5941 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5942 place sucks, they are utility functions and should be in some
5945 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5947 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5950 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Added TRQ (efficient deque and list library) into lib/trq. This is
5955 a very good list library that is currently used in the SILC. Defined
5956 SilcList API over the library because I didn't like the API very
5957 much. See lib/trq/silclist.h for the API and examples of how to
5958 use the API. Fixed various places in the code to use the new
5959 SilcList API. The SilcList is meant for lists that has a structure
5960 already defined as a list. It is not suitable to add just some
5961 context to the list (in TRQ, the context is the list actually).
5963 So, I defined SilcDList that can be used for the purpose where
5964 predefined list structure does not exit. This can be used as
5965 such list. Now some context just can be added to the SilcDList.
5966 Currently this list is not used in the SILC just yet, though there
5967 are a lot places where this can replace dynamically allocated
5968 tables and I will fix these places, later, to use SilcDList.
5969 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5970 and use TRQ internally).
5972 Also fixed some annoying warning messages that the original TRQ
5973 code generated. Also minor changes to TRQ's Makefile.in.
5975 * Added support for querying by Client ID to both WHOIS and
5976 IDENTIFY commands into server, as required by the protocol.
5978 * Removed method function pointers from SilcBuffer structure. They
5979 weren't used to anything and just increased the context size for
5980 no good reason. This change also made silc_buffer_alloc and
5981 silc_buffer_free functions inline functions.
5983 * Disabled command flooding detection support until it's fixed so
5984 that it accepts commands in but does not execute them more than once
5987 * Added silc_net_localhost(), to return local hostname, into
5988 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5989 that must be initialized before calling silc_client_init.
5991 * Added new function: silc_server_send_notify_on_channels to send
5992 notify messages to all channels client has joined. It is assured
5993 that the message is sent only once per client.
5995 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5996 lib/silcutil/silcutil.[ch] as silc_format function. The new
5997 function is generic and is used by server as well, not only by
5998 the logging routines.
6000 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6001 the provided version string was not acceptable. Added new function:
6002 silc_ske_check_version into lib/silcske/silcske.h. The function
6003 must be implemented by the application (client or server) and it
6004 does not reside in the SKE library. The function checks the version
6005 string remote end sent.
6007 * Added back pointers (to opaque context and to SilcSocketConnection)
6008 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6010 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6011 duplicate packet context structure.
6013 * Changed `notify' client operation to send same arguments as client
6014 receives from server except for ID's. ID's are mapped to correct
6015 ID entry and that is returned. Also, if channel entry is not sent
6016 by server but the notify is for channel the channel entry is sent
6017 to application (otherwise application doesn't know that it is for
6018 channel (library gets it from packet's Destination ID)).
6020 * Added silc_client_remove_from_channels into client library to
6021 remove a client from all channels it has joined to. Used when
6022 received SIGNOFF notify from server. Added also new function
6023 silc_client_replace_from_channels to replace old ID entry with
6024 new ID entry on all channels. Used when received NICK_CHANGE
6027 * Fixed ID Cache list handling in silc_idlist_get_client in
6028 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6029 to get (or query) client by ID.
6031 * Updated TODO list.
6033 * Added connection authentication status message defined by the
6034 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6035 support for these into the code in client and server side.
6037 * Added generic function silc_client_send_command to send any command
6038 with variable argument list. Application should use this function
6039 to send commands if the command functions provided by the library
6040 does not suite for the application's user interface needs.
6042 * Added new `failure' client operation. Application is notified about
6043 received failure packet if client is executing a protocol. In this
6044 case the protocol's execution has failed.
6046 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6047 is required by the protocol.
6049 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6050 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6053 * Added status flag to SilcSKE object to indicate realtime status
6054 of the SKE protocol.
6056 * Application receives now exactly same command reply arguments as
6057 the library receives from server. However, if ID is received the
6058 corresponding ID entry is returned to the application (eg. Client
6059 ID is mapped to correct SilcClientEntry entry and that is returned).
6060 Changed command_reply client operation due to this change.
6062 * Changed all ID's in commands and in command replys as ID Payloads.
6063 Change affected both client and server side codes.
6065 All ID's sent in SILC network (with execption of ID's in SILC
6066 Packet header) are sent in ID Payload to support variable length
6069 * Server now notifies nick changes and notifies all clients on
6070 the channels about the new nickname (about the new Client ID,
6073 * Implemented CMODE command to change channel modes. Supports all
6074 channel modes defined by the protocol specs except ban and invite
6075 lists. (Also, private channel key mode is supported but support for
6076 setting private channel key in client is missing, thus, this mode
6077 has no effect on client side (except that server requires that the
6078 client uses private channel key and normal channel traffic does not
6081 Also, invite mode works per se, but INVITE command does not work
6082 yet correctly, so you can set channel as invite only channel but
6083 inviting clients to the channel does not work (it is yet to be
6084 thought what's the best way to do it).
6086 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6087 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6088 Implemented CUMODE command to change user's mode on the channel.
6089 Supports all modes defined by the protocol specs.
6091 * Added NAMES command reply to return users modes on the channel.
6093 * Removed unnecessary and slow ciphers from lib/silccrypt.
6095 * Set SO_KEEPALIVE option to connection sockets by default.
6097 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6099 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6100 redefined the Notify Payload into protocol specs.
6102 * Added silc_id_payload_parse_id to get ID directly from raw
6105 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6108 accept searching by Client ID as well.
6110 * Added support for LEAVE and SIGNOFF notify types in client library.
6112 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6113 to parse ID Payload from raw data.
6115 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * Added flags parameter into silc_ske_assemble_security_properties
6118 function in lib/silcske/silcske.[ch].
6120 * Changed notify client operation to fit better for notify messages
6121 sent by server. The notify payload received from server is now
6122 passed to the application (after parsing it to SilcNotifyPayload).
6123 It is application's responsibility to retrieve the arguments
6124 from the payload and show the message the way it wants. The message
6125 sent by server is implementation specific.
6127 * Changed public keys to comply with the protocol specification.
6128 Old public keys are not supported anymore and are not compatible.
6130 * Removed nickname from Channel Payload as the latest draft removed
6131 it. The client must resolve the nickname from the NAMES command
6132 reply received when it joined the channel.
6134 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6136 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6138 * Fixed some errors in protocol specification drafts.
6140 * Created lib/silccore/silcnotify.c to implement Notify Payload
6141 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6142 generic payloads described by protocol specifications. The file
6143 includes implementations for ID Payload and Argument Payload.
6145 * Changed Command Payload implementation to use the new Argument
6146 Payload. Changed command_xxxx_payload to command_payload_xxxx
6147 to comply with SILC coding conventions.
6149 * Added suppport for Argument Payload handling in Notify Payload
6150 implementation as protocol requires it. Added the new support
6151 into server and client lib as well.
6153 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * Added support for multiple nicknames on same channel. [n] is
6156 added locally to the nickname if there are more than one same
6157 nicknames on the channel.
6159 * Server now sends all nicknames that matched WHOIS request.
6160 Client also shows the list received from server.
6162 * Added TOPIC command to client side. User can now set and show
6163 current topic on channel.
6165 * Added MOTD command to client and server. Also, server sends the
6166 motd when client connects to the server.
6168 * Changed version strings to comply ISO 8601.
6170 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Fixed protocol error handling in client library. It should now
6173 cope even if the SKE fails for some reason.
6175 * Made new protocol specification drafts for submitting to IETF.
6177 * Implemented TOPIC command to server in silcd/command.c.
6179 * Added two new notify types into lib/silccore/silcnotify.h:
6180 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6181 notify nickname change and topic setting/change on a channel.
6183 * API change of command_reply operation in client library. The
6184 application gets now the status type received from server as well.
6186 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6188 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6190 * Cras fixed and optimized the packet handling even further and
6191 it should work now. Minor change to the prototype of function
6192 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6194 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Added new function into lib/silcutil/silcschedule.[ch]:
6197 silc_schedule_with_fd to select() a specified fd. The function
6198 returns after timeout expires or data arrives or goes. The
6199 function is used by packet routines to wait that all data is
6200 received from network.
6202 * Fixed data reading from network in lib/silccore/silcpacket.c.
6203 The code now assures that all data is read from the fd and then
6204 continues packet processing. This was a bug fix since the code
6205 used to drop some data in some circumstances.
6207 * Added new function into lib/silcclient/client.[ch]:
6208 silc_client_start_key_exchange to start key exchange after
6209 connection has been established to server. The code internally
6210 now uses this funtion but its main purpose was to provide it
6211 for applications that perform their own connecting. After
6212 application has created a connection it merely calls this
6213 function to start the key exchange between client and server.
6214 The library takes care of everything else after that.
6216 Updated also lib/silcclient/README to explain the usage of
6219 * Do not send to application information that connection has
6220 been established. Application gets notified it by connect
6223 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Applied cras's patch to add silc_schedule_one function. The
6226 function runs scheduler once and returns.
6228 * Fixed the scheduler after cras messed it up. The timeout
6229 handling works now as it's supposed to work.
6231 * Added into lib/silccore/ silcnotify.h to include notify
6232 message types support. Changed silc_server_send_notify*
6233 functions, in server.[ch], to support those new notify types.
6234 Added the support for the notify types into client library,
6235 as well. Added new notify client operation into ops.h in
6238 * Changed silc_server_packet_send_to_channel to send normal
6239 packets instead of just channel message packets. The function
6240 is now used to send the notify packets to channels. It is not
6241 used to send channel message packets anymore, as server never
6244 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6245 va_arg()s as it seems to require it nowadays. I guess, if SILC
6246 is compiled with older va_arg() the new code should work anyway.
6248 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Splitted core library. Core library (lib/silccore) includes
6251 now only SILC protocol specific core (and common) components.
6252 Created new utility library (lib/silcutil) that includes more
6253 generic purpose stuff. The stuff for util library was taken
6254 from the old core library. This was minor and easy split.
6256 * Created SILC Client Library (lib/silcclient) that includes
6257 implementation of the SILC client without user interface. This
6258 was major move from silc/ directory. The code has been changed
6259 so that it is transparent towards the user interface. The
6260 silc/ directory includes now the same user interface as before
6261 and it uses the new client library. Read lib/silcclient/README.
6262 Basicly, the client library performs everything else related
6263 to SILC except user interface handling. Also, configuration
6264 files are considered to be part of user interface and library
6265 does not handle them.
6267 This change also changed a lot of structures, function naming etc.
6268 Most important change was that SilcClientWindow object was
6269 renamed to SilcClientConnection in the client library. Created
6270 also new file lib/silcclient/ops.h. Also added new files
6271 silc/local_command.[ch] and silc/client_ops.[ch].
6273 All these changes were made to make it easier for user interface
6274 designers to create what ever user interface for the SILC client
6277 It is also expected that the server will be moved to lib
6278 directory as well and SILC Server Library will be created;
6279 sometimes in the future.
6281 * Removed Local commands from lib/silccore/silccommand.h as
6282 they are application specific and new client library does not
6283 handle any of those anymore.
6285 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6286 old client implementation in silc/.
6288 * Added support for callback functions in SILC_LOG_* macros.
6289 Application can now set its own callbacks that will be called
6290 instead of using the default functions that will always print
6291 the debug messages to stderr (or stdout). Also, debugging can
6292 now be disabled by setting silc_debug to FALSE and re-enabled by
6293 setting it to TRUE. Note, that logging will still work even
6294 if debugging is disabled.
6296 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6297 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6298 silc_log_reset_debug_callbacks.
6300 * To enable debugging in silc client one must give now -d
6301 option on command line.
6303 * Changed silc_schedule_init to automatically allocate task queues
6304 if they are not allocated before calling it.
6306 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6308 * Added GMP 3.1 into math library.
6310 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6313 a channel in SILC network. The packet is used by servers and
6314 routers to notify other routers that user has left a channel.
6315 This little feature was missing until now. Added the feature
6316 to protocol specification as well.
6318 Added functions: silc_server_send_remove_channel_user and
6319 silc_server_remove_channel_user into server.[ch].
6321 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6322 lib/silccore/silcpacket.h. However, they are not implemented
6325 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Fixed joining to a channel and sending channel messages
6328 between server and router. The channel message sending should
6329 now work inside a cell.
6331 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * Fixed the private message sending between server and router.
6334 The private message sending should now work inside a cell.
6336 * Added silc_server_replace_id into server.[ch] to replace
6337 existing ID in the SILC network.
6339 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6340 and silc_idlist_replace_server_id into idlist.[ch] in server.
6342 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Fixed the server to server connections. Server can again now
6345 connect to router. Router to router connections probably does
6348 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Added dynamic protocol registering support. Now protocols can
6351 registered and unregistered on the fly. Patch by cras.
6353 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Added lib/contrib directory to hold routines that some platforms
6356 don't have but are needed by SILC.
6358 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6359 into lin/contrib to provide getopt() and getopt_long() for
6360 those who don't have it.
6362 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Added AWAY command to client. When away message is set and
6365 client receives a private message packet the client automatically
6366 replies to the sender with the away message.
6368 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6369 bug seemed to be the cause of recent problems when compiling
6372 * Added version detection support to SKE protocol specification
6373 and added the new changes to the SKE implementation as well.
6374 There were other minor changes in the SKE protocol as well.
6376 Many changes in lib/silcske/silcske.[ch] and in
6377 lib/silcske/payload.[ch].
6379 * Added ^U functionality, clear input line. Patch from cras.
6381 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6383 * Mainly small bugfixes on core library. Fixed some debugging
6384 logging and buffer overflow in silclog.c.
6386 * Updated config.sub and config.guess on the distribution tree.
6388 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Added command lagging support in server. Client may execute
6391 commands now only once in two seconds.
6393 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6395 * Optimized packet reception. MAC computation and checking is now
6396 also more optimized. A lot previously duplicated code is now
6397 used as generic by both client and server.
6399 * Fixed key pair generation in clientutil.c
6401 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Added into lib/silccore/silcbufutil.[ch] new function;
6404 silc_buffer_realloc.
6406 * Moved generic packet sending/encryption functions to
6407 lib/silccore/silcpacket.[ch] from client and server. Some
6408 rewriting of the functions.
6410 * Moved all generic packet reception/decryption functions to
6411 lib/silccore/silcpacket.[ch] from client and server. The
6412 packet processing is now much cleaner in both client and server.
6413 These were major changes in both client and server.
6415 * Created many common functions in server to do packet sending.
6416 Previously code were duplicated a lot, this has been removed
6419 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6421 * Rewrote major parts of the ID cache system. Don't know
6422 whether it is better now or not but at least the API is more
6425 * Major rewrite on ID cache stuff on client because of the ID
6426 cache API changes. Added idlist.c to client.
6428 * Also major rewrite on ID cache stuff on server as well.
6429 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6430 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6431 in hand, instead they are all put into the ID cache system now.
6432 All server_idlist_* routines uses ID cache now instead of
6433 traversing its own lists (those lists does not exist anymore).
6434 SilcIDList though still exists. Also, SilcXXXEntry's are
6437 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6439 * Finally made the SKE implementation compliant to the protocol
6440 specification. All mp integers are now binary encoded as
6441 opposed being HEX encoded.
6443 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6446 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6447 functions: silc_[encode/decode]_pem. Also added function
6448 silc_encode_pem_file to PEM encode with newlines ('\n') for
6451 * SILC public keys are now encoded either PEM or binary. Same
6452 option is for private keys as well. By default private keys
6453 are binary encoded and public keys PEM encoded. Silly HEX
6454 encoding were removed.
6456 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6457 function to create fingerprints.
6459 * Fixed a bug in SHA1; does not change the original data anymore.
6461 * Partly implemented INFO command on client and server side.
6462 Fixed CLEAR command. Changes to SERVER command; show current
6463 server(s) when giving command without arguments. Added
6464 VERSION command to client.
6466 * Added check to server that unregistered connections cannot
6467 execute commands (unless it is specificly allowed).
6469 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6471 * Fixed screen refresh.
6473 * Fixed channel joining bug from client. On some circumstances
6474 client tried to join to a channel it had already joined.
6476 * Added public key verification process into client's protocol.c.
6477 The client now verifies the public key from user and saves
6478 it into ~./silc/serverkeys/ directory.
6480 Added into: clientutil.[ch]: silc_client_verify_server_key.
6482 * Changed SKE protocol's silc_ske_initiator_finish function
6483 to accept callback function that verifies the received public
6484 key. Removed old silc_ske_verify_public_key function.
6486 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6489 silc_pkcs_private_key[_data]_set.
6491 * Made the password and public authentication more cleaner in
6492 server's protocol.c.
6494 * Removed historic and obsolete protocol `channel_auth' from
6495 both client and server.
6497 * Removed wrong way of sending command status messages from
6498 server to client in server's command.c. The old way violated
6499 protocol specification.
6501 Changes to silccore/silccommand.[ch]: removed
6502 silc_command_encode_status_payload -> not needed anymore,
6503 changed silc_command_encode_payload_va to accept extra
6504 argument on variable argument list. The argument type must
6505 now be provided to the function. Also, added new function:
6506 silc_command_encode_reply_payload_va which is same as
6507 normal command_encode_payload_va except command status type
6508 is provided as extra argument.
6510 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6512 * Added ~./silc directory handling. The directory includes the
6513 public and private keys for the client.
6515 Added silc_client_check_silc_dir, silc_client_create_identifier
6516 and silc_client_load_keys.
6518 * Implemented SILC protocol compliant public key. Added public
6519 and private key saving to and loading from files.
6521 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6522 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6523 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6524 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6525 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.

6532 * Added silc_server_get_route (route.[ch]) to get connection
6533 data for the fastest route for given ID.
6535 * Implemented INVITE command on client and server. The command
6536 were re-defined in the SILC Protocol Specification and the
6537 implementation now complies with the specification.
6539 * Implemented PING command on client and server.
6541 * Implemented NAMES command on client and server. The server side

6555 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
