1 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed minor bug in IDENTIFY command reply sending, which
4 caused various weird problems during JOIN when it was
5 resolving names for users. Affected file silcd/command.c.
7 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Fixed the IDENTIFY command reply sending to chech better valid
10 clients. It was possible to send incomplete list of replies.
11 Affected file silcd/command.c.
13 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
15 * Added silc_client_command[s]_[un]register functions now to
16 dynamically register the commands in client library. Removed
17 the static table of commands. This allows the client library
18 to call commands without causing the application to know about
19 what commands library has called.
21 Removed the INFO command reply kludge to detect when the command
22 was called by library. Now library use its own command reply
23 function for INFO command.
25 Added function silc_client_command_call to call a command.
26 Application can use it to call command, not access the structure
29 Now all commands that are sent by the client library (not
30 explicitly sent by application) use own command reply functions.
32 Affected files around lib/silcclient/ and in
35 * Fixed the WHOIS command reply sending to chech better valid
36 clients. It was possible to send incomplete list of replies.
38 Fixed the WHOIS and IDENTIFY to send the request to router
39 if normal server did not do it and did not find any results.
41 Affected file silcd/command.c.
43 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
45 * Moved the internal data from SilcClient context into its
46 own file, not accesible to application. Affected files
47 lib/silcclient/client.h and lib/silcclient/client_internal.h,
48 and other files in client library.
50 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
52 * Added doc/examples installation target in Makefile.am.pre.
55 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
57 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
58 commands the found client entry will be removed from the
59 cache, after notifying application about the error. Affected
60 file lib/silcclient/command_reply.c.
62 * Changed the /MSG to check for exact nickname user gave, and
63 not let `nick' match `nick@host' if it is only one found. Now,
64 user must type the exact nickname (like nick@host2) even if
65 there are no more than one same nicks found. This is to avoid
66 a possibility of sending nickname to wrong nickname since
67 `nick' could match `nick@host'. Affected file is
68 irssi/src/core/silc-servers.c.
70 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
72 * Do not print "you are now server operator" or similar when
73 giving /away command. Affected files are
74 irssi/src/silc/core/client_ops.c, silc-servers.h.
76 * Made the silc_server_command_pending_error_check to send
77 the same command reply payload it received back to the
78 original sender of the command. This way all arguments
79 that was received by the server will be received by the
80 client too. Affected file silcd/command.c.
82 * Added the silc_idcache_add to return the created cache entry
83 to a pointer. Affected file lib/silccore/silcidcache.[ch].
85 * Add global clients to expire if they are not on any channel.
86 This is because normal server will never know if they signoff
87 if they are not on any channel. The cache expiry will take
88 case of these entries. This is done by normal servers only.
89 The affected files are silcd/command_reply.c,
90 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
92 * If server receives invalid ID notification for WHOIS or
93 IDENTIFY and the ID exists in the lists, it is removed.
94 Affected file silcd/command_reply.c.
96 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
97 in client then client entry that it matches is searched and
98 the nickname is printed on the screen for user. Affected
99 file irssi/src/silc/core/client_ops.c.
101 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
103 * Use cache entry expire time in the LIST command reply to
104 purge old entries from the cache after the LIST command
105 reply has been received. This way we don't have non-existent
106 entries in the cache for too long. Affected file is
107 silcd/command_reply.c.
109 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
111 * If we are normal server, and we've not resolved client info
112 in WHOIS or IDENTIFY from router, and it is global client,
113 we'll check whether it is on some channel. If it is not
114 then we cannot be sure about its validity and will resolve it
115 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
116 file silcd/command.c.
118 * Search channel by name (if possible) rather than by ID
119 in IDENTIFY command's command reply. Affected file is
120 silcd/command_reply.c.
122 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
124 * Distribute to the channel passphrase in CMODE_CHANGE notify.
125 Updated specs and implemented it. Affected file silcd/command.c,
126 silcd/packet_send.c and silcd/packet_receive.c.
128 * Implemented the <founder auth> payload handling in the JOIN
129 command. If provided all conditions for channel joining
130 except requirement to provide correct passphrase can be
131 overrided by the channel founder. Updated the protocol specs.
132 Affected file silcd/command.c.
134 Added support for founder auth in JOIN command in client
135 library. Fixed the parsing of the JOIN command now to support
136 all options as they should be. The affected file is
137 lib/silcclient/command.c.
139 * Optimized the WHOIS and IDENTIFY commands to send the request
140 to router only if it includes nicknames or other names. If
141 they include only IDs then check the local cache first before
142 routing. Affected file is silcd/command.c.
144 * Added channels topic announcements. Affected file is
145 silcd/packet_receive.c and silcd/server.c.
147 * Fixed the silc_server_send_notify_topic_set to really destine
148 the packet to channel. Affected file silcd/packet_send.c.
150 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
151 library. Affected file lib/silcclient/client_notify.c.
153 * Added UMODE announcements. Affected file silcd/server.c.
155 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
157 * Memory leak fixes in:
159 lib/silcutil/silcsockconn.c
160 lib/silcske/silcske.c
163 lib/silccrypt/silcpkcs.c
164 lib/silccore/silccommand.c
165 lib/silccore/silcidcache.c
170 * ROBOdoc documented the lib/silcske/groups.h file and a
171 bit changed the interface for better.
173 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
175 * Update the client entry context in the ID cache after
176 nick change. Affected file lib/silcclient/command.c.
177 Fixes the CUMODE command when regaining founder privileges,
178 and a little WHOIS problem.
180 * Fixed silc_net_gethostbyname to correctly call the
181 inet_ntop. Affected file lib/silcutil/silcnet.c.
183 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
185 * Added IPv6 support checking to the configure.in.pre, added
186 also --enable-ipv6 option to override the check. Affected
187 file configure.in.pre.
189 * The silc_thread_create now calls the start function
190 directly if threads support is not compiled in. Removes
191 ugly #ifdef's from generic code. Affected files are
192 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
194 * Added silc_net_gethostby[name/addr]_async to asynchronously
195 resolve. Affected files are lib/silcutil/silcnet.[ch].
197 * Added support for rendering IPv6 based server, client and
198 channel IDs. Affected file lib/silcutil/silcutil.c.
200 * Added support for creating IPv6 based server IDs. Affected
201 file is silcd/serverid.c.
203 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
205 * Added silc_net_gethostby[addr/name] into the
206 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
207 routines. Added silc_net_is_ip[4/6]. Affected file is
208 lib/silcutil/unix/silcunixnet.c. All routines that take
209 address as argument now supports both IPv4 and IPv6 addresses.
211 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
213 * Fixed LIST command reply sending in server. Affected file
216 * Server now sends the kicker's client ID in the KICK notify
217 to the kicked client. Affected file silcd/command.c.
219 * The client library now parses the kickers client ID and
220 UI displays it. Affected files lib/silcclient/client_notify.c
221 and irssi/src/silc/core/silc-channels.c, module-formats.c.
223 * Made all payload parsing function prototypes consistent.
224 They all take now const unsigned char * and uint32 pair as
225 the payload data instead of SilcBuffer. Changes all around
226 the source tree. Other unsigned char* -> const unsigned char*
227 changes around the tree as well.
229 * Optimized SFTP client and server packet sending not to
230 allocate new buffer for each packet but to recycle the
231 first allocated buffer. Affected files are
232 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
234 * Optimized the SFTP client to use SilcList instead of
235 SilcDList for requests, because it is faster. Affected file
236 is lib/silcsftp/sftp_client.c.
238 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
239 into lib/silccore/silcid.[ch].
241 Renamed silcpayload.[ch] into silcargument.[ch].
243 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
245 * If client entry is deleted with active key agreement
246 session, abort the session.
248 The silc_client_abort_key_agreement now calls the completion
249 callback with new SILC_KEY_AGREEMENT_ABORTED status.
251 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
254 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
256 * Don't use __restrict in older GCC's. Affected file is
257 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
259 * silc_net_localhost now attempts to reverse lookup the
260 IP/hostname. Affected file lib/silcutil/silcnet.c.
262 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
263 command. It can be used to gain founder privileges at
264 the same time when joining the channel.
266 Defined that the SILC_NOTIFY_TYPE_KICKED send the
267 kicker's client ID as well. Updated protocol specs.
269 Defined that the server must send SILC_COMMAND_IDENTIFY
270 command reply with error status to client who sent
271 private message with invalid client ID.
273 Updated the protocol specification.
275 * Added silc_server_send_command_reply to send any
276 command reply. Affected file silcd/packet_send.[ch].
278 * Added silc_id_payload_encode_data to encode ID payload
279 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
281 * The server now send IDENTIFY command reply with error
282 status if client ID in private message is invalid. Affected
283 file silcd/packet_receive.c.
285 * Save the server key file with server's IP address in
286 the filename instead of hostname. The affected file is
287 irssi/src/silc/core/client_ops.c.
289 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
291 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
294 * Added libtool support for compiling shared objects in
295 lib/silcsim. Affected file configure.in.pre and
296 lib/silcsim/Makefile.am. Original patch by cras.
298 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
300 * Pid file configuration, and server's config file fixes
301 patch by toma. Updated CREDITS file.
303 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
305 * Fixed silc_client_channel_message to not try to decrypt
306 the message twice if it resolved the destination client
307 information. This could cause of dropping one channel
308 message. Affected file lib/silcclient/client_channel.c.
310 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
312 * Added silc_client_run_one into lib/silcclient/silcapi.h and
313 lib/silcclient/client.c. This function is used when the SILC
314 Client is run under some other scheduler, or event loop or
315 main loop. On GUI applications, for example this may be
316 desired to used to run the client under the GUI application's
317 main loop. Typically the GUI application would register an
318 idle task that calls this function multiple times in a second
319 to quickly process the SILC specific data.
321 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
323 * Fixed silc_server_drop() for dropping the supplementary
324 groups as well, this could cause a security hole on some
327 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
329 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
332 * Write PID file after dropping privileges. Added -F option
333 to run server on foreground. A patch by debolaz.
334 Affected files silcd/server.c, silcd/silcd.c.
336 * Fixed MOTD to return the MOTD file server name. Affected
337 file silcd/command.c.
339 * Added INFO command reply handling to the Irssi SILC Client.
340 Affected file irssi/src/silc/core/client_ops.c.
342 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
344 * Fixed the silc_idcache_list_* routines to really support
345 the dynamic list. Fixes a crash. Affected file is
346 lib/silccore/silcidcache.c.
348 * Fixed the LIST command reply to really call LIST command's
349 pending callbacks. Affected file silcd/command_reply.c.
351 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
353 * Update conn->local_entry->nickname after giving NICK
354 command. Affected file lib/silcclient/command.c.
356 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
358 * Added the [pid] option to the silcd configuration file
360 Affected files: serverconfig.[ch] and silcd.c
362 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
364 * Save fingerprint in WHOIS command reply in server.
365 Affected file silcd/command_reply.c.
367 * Fixed NICK commands pending callback registration.
368 Affected file lib/silcclient/command.c.
370 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
372 * Use ++server->cmd_ident when sending commands in server,
373 instead of random number. Affected file silcd/command.c.
375 * Fixed GETKEY command reply to call actually GETKEY pending
376 command callbacks. Affected file silcd/command_reply.c.
378 * A bit stricter check for nicknames. Check for same nickname
379 in NICK command also. Affected file silcd/command.c.
381 * Do not call INFO command everytime client ID changes, only
382 during first connecting. Affected file lib/silcclient/client.c.
384 * Set the new nickname only after successful command reply for
385 NICK command is returned by server. Affected file
386 lib/silcclient/command.c.
388 * Remove nicknames from nicklist during server_signoff notify.
389 Should fix /NAMES bit more. The affected file is
390 irssi/src/silc/core/silc-channels.c.
392 * Added `fingerprint' field to the SilcIDListData in the
393 silcd/idlist.h to hold the fingerprint of the client's
396 Send the fingerprint of the client's public key in WHOIS
399 Affected files silcd/command.c, and silcd/idlist.[ch].
401 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
402 create fingerprint from given data.
404 * Show the fingerprint of the client's public key in WHOIS.
405 Affected files irssi/src/module-formats.[ch] and
406 irssi/src/silc/core/client_ops.c.
408 * Format the multiple same nicknames also during JOIN and
409 NICK_CHANGE notifys. Affected file is
410 lib/silcclient/client_notify.c.
412 * Do not print error on screen for invalid private message
413 payload since it can come if someone is sending private
414 messages with wrong key. Affected file
415 lib/silccore/silcprivate.c.
417 * Fixed multiple concurrent /PING crash. Affected file
418 lib/silcclient/command.c.
420 * Changed the wrong ID encoding. All IP addresses must be
421 in MSB first order in encoded format. They were encoded
422 wrong and was in LSB format. Affected files are
423 silcd/serverid.c, lib/silcutil/silcutil.c.
425 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
427 * Call the `connect' client operation through the scheduler
428 in case of error. Affected file lib/silcclient/client.c.
430 * Call the `failure' client operation even if the error
431 occurred locally during a protocol. Affected file is
432 lib/silcclient/protocol.c.
434 * Added support of sending LIST command to router from normal
435 server. This way normal server can get list of all channels
436 in the network too. Fixed the channel list sending in the
437 server too. Affected files are silcd/command.c, and
438 silcd/command_reply.[ch].
440 * Added silc_server_update_channels_by_server and
441 silc_server_remove_channels_by_server. They are used during
442 disconnection of primary router and in backup router protocol.
443 Affected file silcd/server_util.[ch], silcd/server.c and
444 silcd/server_backup.c.
446 * Fixed channel adding to global list in IDENTIFY command
447 reply in server. Affected file silcd/command_reply.c.
449 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
451 * If the incoming packet type is REKEY or REKEY_DONE process
452 that packet always synchronously. Fixes yet another MAC
453 failed error on slow (dialup) connections. Affected file
454 lib/silcclient/client.c and silcd/server.c.
456 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Call check_version SKE callback for initiator too. Affected
459 file lib/silcske/silcske.c.
461 * Implemented fix for security hole found in the SKE that was
462 fixed in the specification few days back; the initiator's
463 public key is now added to the HASH value computation.
464 Added backwards support for the old way of doing it too, for
465 old clients and old servers. Affected file is
466 lib/silcske/silcske.c.
468 * Enabled mutual authentication by default in SKE. If initiator
469 is not providing mutual authentication the responder will
470 force it. This will provide the proof of posession of the
471 private key for responder. The affected files are
472 lib/silcclient/protocol.c and silcd/protocol.c.
474 * Do not cache anymore the server's public key during SKE.
475 We do mutual authentication so the proof of posession of
476 private key is done, and if the server is authenticated in
477 conn auth protocol with public key we must have the public
478 key already. Affected file silcd/protocol.c.
480 * Added new global debug variable: silc_debug_hexdump. If
481 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
482 file lib/silcutil/silclog.[ch].
484 * Fixed compilation warning due to char * -> const char *.
485 Affected files lib/silcutil/silcnet.h, and
486 lib/silccore/silcauth.[ch].
488 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
490 * Fixed CMODE command when new channel key was created. If
491 the creation failed the old key was removed. Next time giving
492 same command would crash the server since the old key was
493 freed already. Affected file silcd/command.c.
495 * Fixed the silc_server_announce_get_channels to not crash
496 on reconnect. Affected file silcd/server.c.
498 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
500 * Added silc_log_set_debug_string function to set a regex
501 string to match for debug output. Only the function names,
502 or filenames matching the given debug string is actually
503 printed. This way it is possible to filter out those debug
504 strings that user is not interested in.
506 Fixed a bug in silc_string_regexify.
508 Affected files lib/silcutil/silclog.[ch], and
509 lib/silcutil/unix/silcunixutil.c.
511 * Changed the -d options in both server and Irssi SILC client
512 to take the debug string as argument. Affected files
513 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
515 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
517 * Added silc_hash_babbleprint to create a Bubble Babble
518 Encoded fingerprint. The encoding is developed by Antti
519 Huima (draft-huima-babble-01.txt), and it creates human
520 readable strings out of binary data. Affected file
521 lib/silccrypt/silchash.[ch].
523 * Print the babble print now in addition of fingerprint as well
524 in Irssi SILC client. Affected files are
525 irssi/src/fe-common/silc/module-formats.[ch],
526 irssi/src/fe-common/silc/core/client_ops.c.
528 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
530 * Fixed a security problem found in SKE. The initiator's
531 public key too is now added to the HASH hash value creation
532 which is signed by the responder to create the SIGN value.
533 This will prevent anyone in the middle to lie to the responder
534 about the initiator's public key. If this is done now, the
535 man in the middle will get caught. Updated the protocol
538 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
540 * Better installation directory handling. Configure module
541 paths and other paths automatically to example_silc* files
542 in doc/. A patch by toma.
544 * Fixed compiler warning from MPI library, and from SILC RNG.
547 * Added SILC_SERVER_PID_FILE to define the pid file for server.
548 It can be configured with ./configure. A patch by toma.
550 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
552 * Find correct make to use in prepare-clean. A patch by
553 toma. Affected file prepare-clean.
555 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
557 * Added irssi variables use_auto_addr, auto_bind_ip,
558 auto_bind_port and auto_public_ip.
560 * Changed the interface for silc_client_send_key_agreement
561 in lib/silcclient/silcapi.h
565 irssi/src/silc/core/silc-core.c
567 lib/silcclient/silcapi.h

572 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
574 * Added silc_pkcs_public_key_compare to compare two
575 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
577 * Check that the client who set the founder mode on the
578 channel is the same client that is giving the founder
579 mode to itself. It is done by comparing the saved public
580 key (it is saved even in the authentication is passphrase).
581 Affected file silcd/command.c.
583 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
585 * Do not process packet for disconnected socket connection.
586 Affected file lib/silccore/silcpacket.c.
588 * Process the DISCONNECT packet through scheduler in the
589 client library. Affected file lib/silcclient/client.c.
591 * Fixed the silc_client_packet_parse to not to increase
592 the packet sequence number if the conn->sock and the
593 current socket connection is not same. This can happen
594 for example during key agreement when the conn includes
595 multiple socket connections (listeners). Affected file
596 lib/silcclient/client.c.
598 * The sender of the file transfer request now provides also
599 the pointer (listener) for the key exchange protocol. If
600 the listener cannot be created then it sends empty key
601 agreement and lets the receiver provide the listener.
603 Added `local_ip' and `local_port' arguments to the
604 silc_client_file_send. If they are provided they are used,
605 if not then it will attempt to find local IP address, if
606 not found or bind fails then the remote client will provide
609 Affected files are lib/silcclient/client_ftp.c and
610 lib/silcclient/silcapi.h.
612 * Extended the FILE SEND command to support defining the
613 local IP and port for key exchange listener. They are

618 * Defined to WHOIS command reply the sending of fingerprint
619 of the client's public key (if the proof of posession of the
620 corresponding private key is verified by the server).
621 Updated to the protocol specification.
623 * Added support of receiving the client's public key's
624 fingerprint in command reply in client library. Affected
625 file is lib/silcclient/command_reply.c, and
626 lib/silcclient/idlist.[ch].
628 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

642 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
644 * Send error message to application if opening file for
645 writing during file transfer fails. Affected file is
646 lib/silcclient/client_ftp.c.
648 Remove all file transfer sessions for a client that we're
649 removing from ID cache.
651 Affected file is lib/silcclient/client_ftp.c.

681 client library. Affected file lib/silcclient/client_prvmsg.c.
683 * Do not actually remove the client directly from ID cache
684 during SERVER_SIGNOFF, but invalidate it. This way we
685 preserve the WHOWAS info for the client. Affected file
688 * Fixed SERVER_SIGNOFF notify handling in the server. The
689 server is now able to process incoming SERVER_SIGNOFF notify
690 for a server that it doesn't even know about. It will remove
691 the clients provided in the notify. Affected file
692 silcd/packet_receive.c.
694 * Check for partial packet in data queue after every packet that
695 was found from the queue. Return and wait for more data if
696 there is partial data in queue. Affected file is
697 lib/silccore/silcpacket.c.

714 irssi/src/fe-common/silc/module-formats.[ch].
716 * Wrote a help file for FILE command.
718 * Added silc_rng_global_get_byte_fast to get not-so-secure
719 random data as fast as possible. Random data is read from
720 /dev/urandom if available and from the SILC RNG if not
721 available. It is used in padding generation. Affected file
722 lib/silccrypt/silcrng.[ch].
724 * All packets in client library are now processed synchronously.
725 Optimized packet processing a lot. Affected file
726 lib/silcclient/client.c.
728 * All server connection packets are processing synchronously
729 now in server, to optimize packet processing. Affected file
732 * Include files are installed now only in Toolkit distribution
733 if make install is given. Affected files: all Makefile.am's.
735 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
737 * Assure that silc_client_notify_by_server_resolve does not
738 resolve the client information multiple times. If it cannot
739 be found by the first it cannot be found at all. Affected
740 file lib/silcclient/client_notify.c.
742 * Fixed WHOWAS command reply calling. Affected file
743 lib/silcclient/command_reply.c.
745 * Removed all references to silc_idlist_get_client from the
746 Irssi SILC client since that call is internal call used by
747 the library. The Irssi SILC client will use now client
748 retrieval functions found in silcapi.h.
750 * Fixed a bug in resolving nickname info before sending
751 private message. It used freed memory. Affected file
752 irssi/src/silc/core/silc-servers.c.
754 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

773 * Added silc_net_localip to return local host's IP address.
774 Affected file lib/silcutil/silcnet.[ch].
776 * If key exchange or rekey protocol is active for a connection
777 parse all packets syncronously since there might be packets
778 in packet queue that we are not able to process without first
779 processing packets before them. Affected file silcd/server,
780 lib/silcclient/client.c.
782 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
783 whether library should continue processing the packet.
784 Affected file lib/silccore/silcpacket.h.

817 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
819 * Resolve the client info when received private message or
820 channel message for a client which nickname we don't know.
821 Affected files lib/silcclient/client_prvmsg.c and
822 lib/silcclient/client_channel.c.
824 * Do not crash in /KEY if client is not connected. Affected
825 file irssi/src/silc/core/silc-channels.c.
827 * Added SilcClientStatus field to the SilcClientEntry in the
828 lib/silcclient/idlist.h.
830 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
831 is incomplete and is being resolved, it won't be resolved
834 Make sure also that USERS command reply does not resolve
835 twice information. Affected file is
836 lib/silcclient/command_reply.c.
838 Make sure that silc_client_get_clients_by_list does not
839 resolve twice same information.
841 * Check for valid client->id in the silc_server_free_client_data.
842 Affected file silcd/server.c.

857 * Call the silc_server_udpate_servers_by_server in the
858 primary router that comes back online in the backup resuming
859 protocol. Otherwise it routes packets wrong. Affected file
860 silcd/server_util.[ch], silcd/server_backup.c.
862 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
864 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
865 lib/silcutil/silcbuffmt.[ch].
867 * Redefined the SILC packet header to include the padding
868 length. Affected file lib/silccore/silcpacket.[ch].
870 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
871 length for maximum padding up to 128 bytes). Affected
872 file lib/silccore/silcpacket.h.
874 * Removed all backwards support for old 0.5.x MAC thingies.
875 The SILC packet header change makes it impossible to be
876 backwards compatible.
878 * Send the ENDING packet with timeout in the backup resuming
879 protocol. This is to assure that all routers has connected
880 to the primary router. Affected file silcd/server_backup.c.
882 * Changed the RNG to take the first IV from random data. It
883 used to take it from zero actually. Changed the RNG also
884 to use /dev/urandom during session. /dev/random is used
885 in initialization. Affected file lib/silccrypt/silcrng.[ch].
887 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
889 * Changed the SILC packet header to have the first two bytes
890 (the packet length) encrypted. Affected files aroung the
891 code tree, lib/silccore/silcpacket.[ch]. Removed the
892 SilcPacketCheckDecrypt callback. It is not needed anymore
893 since the silc_packet_receive_process will determine now
894 whether the packet is normal or special.
896 * Implemented the unidirectional MAC keys. Affected files
897 lib/silcske/silcske.c, silcd/protocol.c and
898 lib/silcclient/protocol.c.
900 * Implemented the packet sequence number to the MAC computation.
901 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
902 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
903 lib/silcclient/protocol.c.
905 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Allow backup router to announce servers. All servers
908 announced by backup router are added to the global list
909 automatically. Update hte server's socket to our primary
910 router also when backup router announces a server.
911 Affected file silcd/packet_receive.c.
913 * Do not update the client->router in the function
914 silc_server_udpate_clients_by_server if the client is on
915 global list. We might fail to find any specific server
916 for locally connected clients and local cell clients. They
917 should still use the `from' and not `to' as client->router.
918 This fixes backup router resuming protocol. Affected file
921 * Decrease channel statistics count only if the channel
922 deletion worked. Affected files are silcd/server.c and
925 * Added silc_server_update_servers_by_server to update origin
926 of all server entries. Used during backup router protocol.
927 Affected files silcd/server_util.[ch], silcd/server.c. and
928 silcd/backup_router.c.
930 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
931 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
932 silc_hmac_get_hash and silc_hmac_get_name. Affected file
933 lib/silccrypt/silchmac.c.
935 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
937 * Assure that router cannot reroute the same channel message
938 to the sender. Affected file silcd/packet_receive.c.
940 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
942 * Made better checks that the channel message is not sent
943 to the router it came from. Affected file is
944 silcd/packet_send.c. Fixed memory leak too.
946 * Announce informations for incoming router connection, but
947 only after checking if it is replaced by backup router.
948 Affected file silcd/packet_receive.c.
950 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
952 * Fixed the backup resuming protocol to work in multiple
953 router environment. Affected file silcd/server_backup.c.
955 * Route packet only to one router in the function
956 silc_server_packet_send_to_channel. Affected file is
959 * Fixed silc_server_send_notify_dest to set the broadcast
960 flag. Fixed the silc_server_send_notify_topic to actually
961 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
962 Affected file silcd/packet_send.c.
964 * Changed the SFTP Filesystem interface. Changed the
965 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
966 the filesystem operation function. The SilcSFTPFilesystem
967 is now a context that is allocated by all filesystem allocation
968 functions and it already includes the operations structure
969 and filesystem specific context. It is given as argument
970 now to the silc_sftp_server_start. This made the interface
971 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
972 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
974 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
976 * Changed the backup router adding and getting interfaces
977 in the server. The router that will be replaced by the
978 specified backup router is now sent as argument. Affected
979 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
982 * Added silc_net_addr2bin_ne to return the binary form of
983 the IP address in network byte order. Affected files
984 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
986 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
988 * Check for existing server ID in silc_server_new_server
989 and in silc_server_connect_to_router_final and remove the
990 old entry if it exists. Affected file silcd/packet_receive.c,
993 * Send the channel message always to only one router, either
994 in upstream or downstream. Affected file is
997 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
999 * Wrote the definition of the backup resuming protocol to the
1000 protocol specification.
1002 * Removed one redundant channel key generation from normal
1003 server during joining procedure. Removed one redundant
1004 channel key sending from server to router during joining
1005 procedure. Affected file silcd/command.c.
1007 * Made minor bugfixes to the backup router resuming protocol.
1008 Affected file silcd/server_backup.c, server.c.
1010 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1012 * Added --disable-asm configuration option. Affected files
1013 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1016 * Implemented the backup resuming protocol that is used to
1017 resume the primary router position in the cell after the
1018 primary router comes back online. Affected files
1019 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1020 and silcd/server_util.[ch].
1022 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Sleep two (2) seconds after sending QUIT command to server.
1025 Affected file lib/silcclient/command.c.
1027 * Assure that if outgoing data buffer is pending do not force
1028 send any data. Affected file silcd/packet_send.c.
1030 * Assure that if outgoing data buffer is pending do not force
1031 send any data. Affected file lib/silcclient/client.c.
1033 * Implemented the backup router support when the primary router
1034 goes down. The servers and routers can now use the backup
1035 router as new primary router without loosing connectivity.
1037 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1039 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1040 in the server to indicate disabled entry. All data read
1041 from the connection will be ignored and no data is sent
1042 for entry that is disabled. Affected files are
1043 silcd/idlist.h, silcd/server.c.
1045 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1047 * Created SFTP client and server test programs in the
1048 lib/silcsftp/tests directory.
1050 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1052 * Implemented memory filesystem (virtual filesystem) for
1053 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1056 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * Implemented the SFTP (SSH File Transfer Protocol) to the
1059 lib/silcsftp. It includes SFTP client and SFTP server
1062 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1064 * Moved lib/silccore/silcprotocol.[ch] to the
1065 lib/silcutil library.
1067 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1068 take variable argument list pointer as argument. Affected
1069 file lib/silcutil/silcbuffmt.[ch].
1071 * Added silc_buffer_set function that is used to set data
1072 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1073 Affected file lib/silcutil/silcbuffer.h.
1075 * Changed various routines in the core library to use the new
1076 silc_buffer_set instead of allocating new buffer only for
1079 * Added 64-bit value formatting and unformatting support to the
1080 silc_buffer_[un]format routines. Affected file is
1081 lib/silcutil/silcbuffmt.[ch].
1083 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1084 to includes/bitmove.h.
1086 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1088 * Fixed channel user mode saving in client library. Affected
1089 file lib/silcclient/command[_reply].c.
1091 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1093 * Defined the file transfer to the SILC Protocol. Added
1094 new packet type SILC_PACKET_FTP and defined File Transfer
1095 Payload. The mandatory file transfer protocol is SFTP
1096 (SSH File Transfer Protocol). Affected file in addition
1097 of the internet draft is lib/silccore/silcpacket.h.
1099 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1100 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1101 is used as part of backup router protocol when the primary
1102 router of the cell is back online and wishes to resume
1103 the position as primary router.
1105 * Redefined the MAC generation keys in the protocol. The
1106 same key is not used anymore in both direction. Both
1107 direction will now use different keys for sending and
1108 receiving. This fixes a potential security flaw. This
1109 change causes incompatibilities in the protocol.
1111 * Redefined also the MAC computation from the packet.
1112 An packet sequence number is now added to the MAC
1113 computation. This prevents possible replay attacks against
1114 the protocol. This change too causes incompatibilities
1117 Added `sequence' field to the SilcPacketContext to hold
1118 the current sequence number for the packet.
1120 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Added `created' field to the SilcIDListData in the file
1123 silcd/idlist.h to indicate the time when the entry was
1126 * Added `created' field to the SilcChannelEntry too. Affected
1127 file silcd/idlist.h.
1129 * Added `creation_time' aguments to all the announcement functions
1130 in the server. If it is provided then only the entries that
1131 was created after the provided time frame are actually
1132 announced. Affected file silcd/server.[ch].
1134 * The protocol says that the Channel ID's IP address must be
1135 based on the router's IP address. Added check for this in
1136 the silc_server_new_channel when processing incoming New Channel
1137 Payload. Affected file silcd/packet_receive.c.
1139 * Print out the correct version with --version in SILC client.
1140 Affected file irssi/src/silc/core/silc-core.c.
1142 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1144 * Fixed WHOWAS command to check for completnes of the client
1145 entry always, not just when the command is coming from client.
1146 Affected file silcd/command.c.
1148 * Added new function silc_server_packet_queue_purge to purge the
1149 outgoing data queue to the network. After the function returns
1150 it is guaranteed that the outgoing packet queue is empty.
1151 Affected file silcd/packet_send.[ch].
1153 * Purge the outgoing packet queue in the rekey protocol's final
1154 callback to assure that all rekey packets go to the network
1155 before quitting the protocol. Affected file silcd/server.c.
1157 * Added silc_client_packet_queue_parse as similar function as
1158 in server to the client library. The affected file is
1159 lib/silcclient/client.c.
1161 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1163 * Splitted silcd/server.c and created silcd/server_util.[ch]
1164 for utility functions.
1166 * Added new socket flag SILC_SF_DISABLED to indicate that the
1167 connection is open but nothing can be sent to or received from
1168 the connection. Affected file lib/silcutil/silsockconn.[ch].
1169 The checking for disabled socket is checked in the low level
1170 silc_socket_write and silc_socket_read functions.
1172 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1174 * Allow only nicknames and channel names that fits into the
1175 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1177 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1179 * When processing JOIN command reply in server check that if
1180 the channel exists in our global list we'll move it the local
1181 list. Affected file silcd/command_reply.c.
1183 * Fixed the check whether client is joined on the channel already
1184 in JOIN command. Affected file lib/silcclient/command.c.
1186 * Fixed the JOIN command reply to check whether the channel
1187 already exists. Affected file lib/silcclient/command_reply.c.
1189 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1191 * Added silc_ske_status_string to map the SKE error numbers
1192 to readable strings. The affected files are
1193 lib/silcske/silcske[_status].[ch].
1195 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Do not show the private channels on the WHOIS channel list
1198 as it is not allowed by the protocol. The affected file is
1201 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Assure that the packet length digged from the actual packet
1204 is something sensible in the silc_packet_decrypt_rest_special
1205 in lib/silccrypt/silcpacket.c.
1207 * Free and NULL the allocated pointer in silc_hmac_alloc if
1208 the HMAC allocation fails. The affected file is
1209 lib/silccrypt/silchmac.c.
1211 * Print the selected security properties to the log files in
1212 the server. Affected file silcd/protocol.c.
1214 * Add SKE's reference counter even if calling the completion
1215 callback manually. Otherwise it goes negative, although it
1216 does not cause any problems. The affected file is
1217 lib/silcske/silcske.c.
1219 * Remove the client entry with short timeout after giving the
1220 KILL command. Affected file lib/silcclient/command.c.
1222 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1223 case all found clients are already disconnected (WHOWAS would
1224 found them) in the server. Affected file silcd/command.c.
1226 * Update the last_receive (time of last data received) to be
1227 updated only when received private or channel message so that
1228 the idle time showed in WHOIS makes more sense.
1230 * Added boolean field `valid' in to the SilcClientEntry in the
1231 client library to indicate whether the entry is valid or not.
1232 This fixes the nickname change bug on channel when changing
1233 the nickname to be same than the old (like nick to Nick) the
1234 nickname formatter doesn't set the new nick anymore to Nick@host.
1235 Affected file lib/silcclient/idlist.[ch].
1237 * Now actually fixed the nickname changing on disconnection.
1238 Added new function silc_change_nick to the Irssi SILC Client.
1239 Affected file irssi/src/silc/core/client_ops.c,
1240 irssi/src/silc/core/silc-nicklist.[ch].
1242 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1244 * Check that the public key exists in the GETKEY command before
1245 trying to encode it. Affected file silcd/command.c.
1247 * Print some notifications on received public keys with GETKEY
1248 command in the Irssi SILC Client. Affected files are
1249 irssi/src/fe-common/silc/module-formats.[ch],
1250 irssi/src/silc/core/client_ops.c.
1252 * Use IDENTIFY command to resolve the server information in the
1253 GETKEY command instead of INFO command. Affected file
1254 lib/silcclient/command.c.
1256 * All command reply functions in the client library now calls
1257 the pending command reply callbacks even if an error has
1258 occurred. The server has done this a long time and now it was
1259 time to move the client library to this as well. Now all
1260 errors can be delivered back to the pending command reply
1261 callbacks if necessary. Affected files are
1262 lib/silcclient/command[_reply].[ch].
1264 * Change the nickname on disconnection back to the username
1265 because in reconnect the server will enforce it to it anyway.
1266 Affected file irssi/src/silc/core/silc-servers.c.
1268 * Fixed a config file parsing bug in the Irssi SILC client.
1269 Affected file irssi/src/silc/core/clientconfig.c.
1271 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * When printing the channel mode on JOIN, verify that the
1274 channel key and channel's HMAC are valid. Affected file
1275 irssi/src/silc/core/client_ops.c.
1277 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1279 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1280 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1281 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1283 * Removed channel key rekey task deleting from the function
1284 silc_server_save_channel_key. Affected file silcd/server.c.
1285 Added explicit timeout task context instead that is used to
1286 delete the task if we are registering a new task before the
1287 new task has elapsed.
1289 * When channel key rekey occurs the client library now saves
1290 the old channel key for a short period of time (10 seconds) and
1291 is able to use it in case some is still sending channel
1292 messages encrypted with the old key after the rekey. Affected
1293 file lib/silcclient/[idlist.h|client_channel.c].
1295 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1297 * Added check to the silc_server_new_id_real to not accept
1298 new ID if it is the sender's own ID. Affected file is
1299 silcd/packet_receive.c.
1301 * Assure that we do not announce ourself or the one we've
1302 sending our announcements when we're router and are announcing
1303 servers to our primary router. Affected file silcd/server.c.
1305 * Fixed silc_server_command_identify_check_client to assemble
1306 correct WHOIS packet. It send corrupted WHOIS packet and
1307 caused problem with router to router connections. Affected
1308 file silcd/command.c.
1310 Fixed also silc_server_command_whois_check the same way
1311 as for the IDENTIFY command.
1313 * Added new SilcIDListStatus to the server in the SilcIDListData
1314 structure. The status now includes the current status of
1315 the entry (like registered, resolved etc.). Affected file
1316 silcd/idlist.[ch]. Defined a bunch of different status types
1317 as well. This replaced the old boolean registered field as well.
1319 Added resolve_cmd_ident field to the SilcClientEntry structure
1320 too so that if the entry is for example being resolved so
1321 another command may attach to the same pending command reply
1322 without requiring to resolve the same entry again. This concept
1323 should optimize the WHOIS and the IDENTIFY resolving under
1324 heavy load by taking away unnecessary resolving for entries
1325 that are being resolved already.
1327 Added support for adding multiple pending commands for one
1328 command idenfier. Affected file silcd/command[_reply].[ch].
1330 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1331 before deleting the data. Otherwise the hash table will have
1332 freed data in comparison functions. Affected file is
1333 silcd/command_reply.c.
1335 * Fixed silc_idlist_replace_client_id to add the new entry to
1336 the cache with NULL nickname. Otherwise there will be invalid
1337 memory as the nickname after the nickname is freed. Affected
1338 file silcd/packet_receive.c.
1340 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1341 saved into wrong slots because the previous number of entries
1342 was not taken into account. Affected file silcd/idlist.c.
1343 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1345 * If we are router and we receive JOIN notify to a channel that
1346 does not have any users then notified client is marked as the
1347 channel founder, as it is it. The affected file is
1348 silcd/packet_receive.c
1350 * Added to the extended hash table API's table_del_*ext functions
1351 the destructor as argument too, so that the caller can decide
1352 which destructor to use or whether to use destructor at all.
1353 Affected file lib/silcutil/silchashtable.[ch].
1355 * Fixed ID Cache purging. It actually deleted the entries from
1356 the hash table after the data was freed. The hash table ended
1357 up comparing freed memory. The affected file is
1358 lib/silccore/silcidcache.c.
1360 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Fixed Irssi SILC client's KILL command's HELP syntax.
1364 * The USERS command now resolves the detailed user information
1365 if the userinfo field is missing. Affected file is
1366 lib/silcclient/command_reply.c.
1368 * Do not print error in silc_file_read if the read file does
1369 not exist. Just silently return NULL. Affected file is
1370 lib/silcutil/silcutil.c.
1372 * Fixed the silc_log_output to not wine about NULL filename
1373 and to not create some bogus " " filename. Affected file is
1374 lib/silcutil/silclog.c.
1376 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Fixed various printing bugs on the user interface in the
1379 Irssi SILC Client. Minor changes that were forgotten from
1382 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1384 * Fixed the configure.in.pre and the compilation and distribution
1385 environment to support the new autoconf 2.52. That version is
1386 now required to compile the CVS trunk.
1388 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1390 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1391 to generally parse user@fqdn format strings. Affected file
1392 lib/silcutil/silcutil.c.
1394 * Added nickname_format and nickname_force_format fields to the
1395 SilcClientParams structure. The first one defines the format
1396 for the nicknames that the library will enforce if the receives
1397 multiple same nicknames. The second one is boolean value and
1398 can be used to force the library to always enforce the format
1399 to the nicknames regardles whether there are multiple nicknames
1400 or not. This configurable formatting was employed to flexibly
1401 support accessing multiple nicknames from the user interface.
1402 The userinterface can now set the nicknames to what ever format
1403 they prefer. Affected file lib/silcclient/silcapi.h.
1405 Added function silc_client_nickname_format to the file
1406 lib/silcclient/idlist.c. It performs the nickname formatting.
1408 Added new field `hostname´ to the SilcClientEntry context.
1409 It holds the hostname of the client. Affected file is
1410 lib/silcclient/idlist.h.
1412 * Irssi SILC Client sets the nicknames in nick@hostn format.
1413 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1414 irssi/src/silc/core/silc-core.c.
1416 The WHOIS printing now also shows both the real nickname and
1417 the formatted nickname so that user knows how to access the
1418 user if there are multiple same nicknames cached. Affected
1419 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1420 printing formatting too to take the hostname now as a separate
1421 argument. The Affected file is
1422 irssi/src/fe-common/silc/modules-formats.[ch].
1424 * Changed the silc_client_get_clients_local to accept the formatted
1425 nickname as argument. It accepts the real nickname too but the
1426 formatted nickname can be used to find the true entry from
1427 multiple entries. Affected file lib/silcclient/silcapi.h and
1428 lib/silcclient/idlist.c.
1430 * Added nickname_format_parse field to the SilcClientParams.
1431 It is a callback function provided by the application to parse
1432 the nickname out of the formatted nickname string. The library
1433 calls it to get the nickname from the formatted string. Since
1434 the application generally knows better the format of the nickname
1435 string it parses it instead of the library, even though library
1436 encodes the formatted string. If the callback function is not
1437 provided then the library will use the string as is. The
1438 affected file is lib/silcclient/silcapi.h.
1440 * All the nickname strings passed to the client library in
1441 commands are now expected to be formatted nickname strings.
1442 If the command does not support the formatted nickname string
1443 it will assume that the sent string is the actual nickname.
1444 Affected file lib/silcclient/command.c.
1446 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Added public key authentication support to OPER and SILCOPER
1449 commands in the client library. Affected file is
1450 lib/silcclient/command.c.
1452 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1454 * Changed the get_auth_methdod client operation to be asynchronous.
1455 It can be async if the application resolves the authentication
1456 method from the server during the negotiation. Added new
1457 SilcGetAuthMeth completion callback that the application will
1458 call after resolving the authentication method.
1460 Added function silc_client_request_authentication_method that
1461 the application can use to resolve the authentication method
1462 from the server. Added also SilcConnectionAuthRequest callback
1463 that the library will call after the server has replied. The
1464 application can call this function if it does not know the
1465 current authentication method.
1467 Affected files are lib/silcclient/client.c and
1468 lib/silcclient/silcapi.h.
1470 * The Irssi SILC client now automatically resolves the authentication
1471 method incase any configuration information is not present (and
1472 currently there never is). The affected file is
1473 irssi/src/silc/core/client_ops.c.
1475 * Fixed public key authentication from the client library.
1476 Affected file lib/silcclient/protocol.c. Changed also the
1477 protocol specification about the public key authentication in
1478 the connection authentication protocol. The actual data to be
1479 signed is now computed with a hash function before signing.
1481 * Fixed the public key authentication from the server as well.
1482 Affected file silcd/protocol.c.
1484 * Removed the mlock()'s from the memory allocation routines.
1485 Affected file lib/silcutil/silcmemory.c. The ./configure does
1486 not check anymore for the mlock(). Affected file is
1489 * Fixed USERS command in server to allow the execution of the
1490 command for private and secret channels if the client sending
1491 the command is on the channel. Affected file silcd/command.c.
1493 * Fixed silc_client_get_clients_local to return the clients
1494 count correctly. It could return wrong value. Affected file
1495 lib/silcclient/idlist.c.
1497 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1499 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1500 types. The assembler optimizations seemed not to like 64-bit
1501 data types. The assmebler optimizations thus are now enabled
1502 also for BSD systems as opposed to only enable them for Linux.
1504 * Do not check for threads at all on BSD systems. Affected
1505 file configure.in.pre.
1507 * Removed -n and -h options from the Irssi SILC Client since
1508 they are not used in silc.
1510 * Fixed the prime generation to assure that the first digit
1511 of the generated random number is not zero since our conversion
1512 routines does not like number strings that starts with zero
1513 digit. If zero digit is seen the random number is regenerated.
1514 This caused some corrupted RSA keys when the zero first digit
1515 was met. Affected file lib/silcmath/silcprimegen.c.
1517 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * Fixed WIN32 configuration in the ./configure script.
1520 Fixed to include xti.h on environments that has it.
1521 Patches by Carsten Ilchmann and andrew.
1523 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Changed the silc_id_create_client_id to be collision
1526 resistant. It is now assured that there cannot be created
1527 two same client ID's. I suspect that some weird bugs in
1528 the server were actually caused by duplicate Client IDs.
1529 Affected file silcd/serverid.[ch]. A router receiving
1530 new ID now also assures and informs the sending server
1531 if the ID caused collision.
1533 * Changed the silc_id_create_channel_id to also assure that
1534 there are no collisions.
1536 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Statement about ignoring the Mutual Authentication flag when
1539 performing rekey with PFS was a bit misleading. It is ignored
1540 if it was set in the initial negotiation, it cannot be even
1541 set in the rekey. Fixed in the ke-auth draft. Started the
1542 new versions of the protocol drafts in the doc/.
1544 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1546 * Fixed a bug in silc_client_command_identify_save when saving
1547 new channel information. The channel name was no duplicated
1548 and caused crash on exit. Affected file is
1549 lib/silcclient/command_reply.c.
1551 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1553 * Fixed the getkey command handling in the server. Send just
1554 empty OK reply to the sender if the key could not be fetched
1555 (but everything else was ok, like the key just was not available).
1556 Changed the public key parameter to optional in the protocol
1557 specs so that empty OK reply can be sent. Affected file
1560 Added a message to Irssi SILC client to tell to user if the
1561 server did not return a public key.
1563 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Fixed a channel key regeneration bug. It registered new
1566 timeout tasks exponentially until all system resources were
1567 used. Affected file silcd/server.c.
1569 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1571 * Added the SILC Document generator to the scripts/silcdoc.
1572 It can be used to generate the Toolkit Reference Manual out
1573 of the source tree. Internally it will also use the RoboDoc
1574 generator now imported in util/robodoc.
1576 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1578 * Added couple of return's in rekey protocol if error orccurred
1579 during the protocol. The execution must be terminated.
1580 Affected file silcd/protocol.c. Also, terminate the protocol
1581 always with timeout.
1583 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1585 * The client's Client ID was created initally from the wrong
1586 nickname (it could have been in format nick@host) in the
1587 silc_server_new_client. Affected file silcd/packet_receive.c
1589 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Added some SILC_LOG_ERROR's to various error conditions
1592 if client could not be added to ID cache. Affected files
1593 silcd/packet_receive.c and silcd/server.c.
1595 * When client's sock->user_data is freed, NULL also the
1596 client->router and client->connection pointers. Added check
1597 for these pointers being NULL to various places around the
1598 code. Affected file silcd/server.c.
1600 * Added client->data.registered == TRUE checks to various
1601 places around the code to assure that unregistered client's
1602 are not handled when it is not allowed. Affected file
1605 * Added `bool registered' fields to all
1606 silc_idlist_[server|client]_get_* routines to indicate whether
1607 the fetched client needs to be registered or not. Affected
1608 file silcd/idlist.[ch].
1610 * Add your own entry as registered to the ID cache in the
1611 server. Affected file server.c.
1613 * Fixed a bug in silc_server_new_server. The SilcServer was
1614 set as the new server's context instead of SilcServerEntry.
1615 This naturally caused some weird bugs.
1617 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1619 * Do not delete the channel rekey task when adding it
1620 for in silc_server_create_channel_key.
1622 * Changed the silc_server_create_channel_key to return
1623 TRUE or FALSE to indicate the success of the channel key
1626 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1628 * Fixed MSVC++ project files and added missing files to
1629 Makefiles under win32/.

1634 does not have it defined. Affected files are
1635 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1637 * Fixed buffer overflow from Irssi SILC Client. Affected
1638 file irssi/src/fe-common/core/themes.c.
1640 * Fixed double free in client library in the file
1641 lib/silcclient/client.c when disconnecting from server.
1643 * Applied double free patch from cras to Irssi SILC client.
1644 Affected files irssi/src/core/[modules/expandos].c
1646 * Fixed the disconnection handling to Irssi SILC Client.
1647 The application must call silc_client_close_connection
1648 in ops->connect client operation in case of failure of
1649 the connection. Affected file is
1650 irssi/src/silc/core/client_ops.c.
1652 * Do not set sock->protocol to NULL in the function
1653 silc_client_close_connection after executing the protocol's
1654 final callback since the sock might not be valid anymore.
1655 Affected file lib/silcclient/client.c.
1657 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Do not enable SILC_THREADS if the linking with libpthread
1660 did not happen. Affected file configure.in.pre.
1662 * Added notion to protocol specification that server must
1663 verify the sent authentication payload with CMODE when
1664 setting the channel founder key. Implemented it to the
1665 server. Affected file silcd/command.c.
1667 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1669 * Added _EXTRA_DIST SILC distribution variable to the
1670 distributions file. It is used to conditionally add extra
1671 files or directories to the specific distribution. Affected
1672 files ./prepare, Makefile.am.pre and distributions.

1677 * Added README.WIN32 for instructions to compile the Toolkit
1680 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * Fixed a double free in disconnection in the server. Affected
1683 file is silcd/server.c.
1685 * Fixed the lib/silcske/groups.c to work now also with GMP
1686 MP library. The string conversion did not work when using
1687 specific base and the base is indicated in the string as well.
1689 * Created win32/ directory which now includes MSVC++ specific
1690 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1691 It will appear only in the toolkit distribution
1693 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1695 * Changed the key material distribution function in case when
1696 the hash output is too short. The data is now concatenated
1697 a bit differently than it used to. Made the change to the
1698 SKE protocol specification.
1700 * Added better GMP detection to configure.in.pre. A patch
1703 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1705 * Fixed a minor bug in SKE that might cause some problem on
1706 some platforms. Affected file lib/silcske/silcske.c.
1708 * Added the cookie checking for initiator in the SKE. It checks
1709 that the responder returns the sent cookie unmodified. The
1710 affected file is lib/silcske/silcske.c. Added new SKE
1711 error type INVALID_COOKIE that can be sent during the
1712 negotiation. Fixed some memory leaks as well.
1714 * Added the "invalid cookie" error message to Irssi SILC client's
1717 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1719 * Added `task_max' field to the SilcClientParams to indicate
1720 the maximum tasks the scheduler can handle. If set to zero,
1721 default values are used. Affected file lib/silcclient/silcapi.h.
1723 * Fixed memory leaks in silc_client_close_connection. Affected
1724 file lib/silcclient/client.c.
1726 * Added silc_client_del_client_entry to client library to free
1727 all memory of given client entry. Affected file is
1728 lib/silcclient/idlist.[ch].
1730 * Added new functions silc_client_del_channel and
1731 silc_client_del_server to delete channel and server entries.
1732 Affected file lib/silcclient/[silcapi.h/idlist.c].
1734 * Removed silc_client_del_client_by_id from silcapi.h.
1736 * Fixed the INFO command to return the server's own info
1737 correctly when querying by Server ID. Affected file is
1740 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * Removed the non-blocking settings in WIN32 code in the
1743 silc_sock_[read/write] and added SleepEx instead. Affected
1744 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1745 of input data is now checked with FIONREAD and ioctlsocket.
1747 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1749 * Call silc_schedule_task_del_by_context in the
1750 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1751 Affected file lib/silccore/silcprotocol.c.
1753 * Call silc_protocol_cancel for active protocols in the
1754 silc_server_close_connection if the funtion
1755 silc_server_free_sock_user_data has not been called.
1756 Affected file silcd/server.c.
1758 * Generic tasks cannot be deleted using the del_by_fd
1759 task deleting function since generic tasks does not match
1760 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1762 * Added a notion to SILCOPER help file that the SILCOPER works
1763 only on router server, not on normal server.
1765 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1767 * Added for WIN32 support for the new scheduler as well.
1768 Affected file lib/silcutil/win32/silcwin32schedule.c.
1770 * Fixed the SHA1 implementation to work on various platforms.
1772 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1775 API. It is part of the scheduler now. Everything else is
1776 as previously but some functions has changed their names.
1777 Checkout the lib/silcutil/silcschedule.h for the interface.
1778 Updated all applications to use the new interface. Affected
1779 files are lib/silcutil/silcschedule.[ch].
1781 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * Found a bug in the SKE implementation. The HASH value,
1784 specified by the protocol, was not computed correctly. The
1785 public key of the responder was not added to the computation
1786 even though it is mandatory. Affected file lib/silcske/silcske.c.
1787 This unfortunately causes incompatibilities with older
1788 clients and servers.
1790 * Added WIN32 specific network init and uninit functions:
1791 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1792 the Winsock2. Affected file lib/silcutil/silcnet.h and
1793 lib/silcutil/win32/silcwin32net.c.
1795 * Set the socket always to nonblocking mode on WIN32 after
1796 reading data or writing data. Affected file is
1797 lib/silcutil/win32/silcwin32sockconn.c.
1799 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1801 * Fixed various compilation problems under WIN32. Affected
1802 files lib/silcutil/win32/silcwin32thread.c and
1803 lib/silcutil/win32/silcwin32schedule.c.
1805 * Removed all _internal.h #includes from public header
1806 files. Internal headers must never be included from
1809 Removed also the lib/silcske/payload_internal.h file.
1811 * All include files that may be needed (public and some others
1812 included by the public headers) by application developers are
1813 now copied to the ./includes directory. It does not copy any
1814 internal headers. Affected file Makefile.defines.pre and all
1815 Makefile.am's under lib/ and subdirs.
1817 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1819 * Do not change the ~/.silc directory's permissions automatically.
1820 Affected file irssi/src/silc/core/clientutil.c.
1822 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Do not cancel the protocol in silc_server_close_connection
1825 it might cause recursion. Now cancelled in the function
1826 silc_server_free_sock_user_data. Affected file silcd/server.c.
1828 * Fixed the silc_server_remove_clients_by_server to regenerate
1829 the channel keys correctly finally. Added also new function
1830 silc_server_remove_clients_channels to actually do it.
1831 Affected file silcd/server.c.
1833 * Fixed the silc_server_new_channel to not crash by giving
1834 wrong router to the new channel. Affected file is
1835 silcd/packet_receive.c.
1837 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1840 which is given as argument to the silc_client_alloc now.
1841 It can be used to configure the client and set various parameters
1842 that affect the function of the client.
1844 * The USERS command in server did not check whether the channel
1845 is private or secret. Affected file silcd/command.c.
1847 * Added new argument to the USERS command in protocol specification.
1848 The USERS command now can take the channel name as argument
1849 as well. Added support for this in client and server and
1850 updated the protocol specs.
1852 * Completed the GETKEY command in client. It can be now used
1853 to fetch also servers public key not only some clients.
1854 Affected files lib/silcclient/command[_reply].c.
1856 * Added silc_client_get_server to return server entry by the
1857 server name. Affected files lib/silcclient/silcapi.h and
1860 * Redefined the IDENTIFY command in protocol specification to be
1861 more generic. It now can be used to query information about
1862 any entity in the SILC Network, including clients, servers and
1863 channels. The query may be based either the entity's name
1864 or the ID. Added support for this in both client and server.
1866 Affected files silcd/command.c and lib/silcclient/command.c
1867 and command_reply.c.
1869 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1870 the _from_client and _from_server functions. Affected file
1873 * Added silc_client_get_channel_by_id_resolve to the file
1874 lib/silcclient/silcapi.h to resolve channel information by
1875 its ID. Added also silc_client_get_channel_by_id that
1876 does not resolve it from the server.
1878 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Added SilcServerEntry context into the client library
1881 to represent one server. The INFO command now allocates
1882 these to save the resolved server info. For now on the
1883 client library will also keep information about servers,
1884 connected and resolved with INFO.
1886 The INFO command now allocates the SilcServerEntry context
1887 and saves the server info there. The COMMAND_REPLY in
1888 the INFO now returns the parameters to application in
1889 same order as defined in the protocol specification.
1891 The entries are cached in the client->server_cache.
1893 * The INFO command is now issued after received the Client ID
1894 from the server. Affected file lib/silcclient/client.c.
1896 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1897 to the application as the mode changer might be server.
1898 It is guaranteed that NULL is not returned anymore to the
1899 application. Affected file lib/silcclient/client_notify.c.
1901 The ID Type is now also passed to the application so that
1902 it can check whether the returned entry is SilcClientEntry
1905 Added new function silc_client_get_server_by_id to return
1906 the server entry by ID. Affected files are the
1907 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1909 * Do not create the channel in the Irssi SILC Client when issuing
1910 the JOIN command but when received the sucessful JOIN command
1911 reply. Otherwise the channel might get created even though we
1912 could not join it. The Affected file is
1913 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1915 * Fixed a channel joining bug in router. The router must also
1916 check the channel modes, invite and ban lists etc. when serving
1917 the JOIN command sent by normal server. Affected file is
1918 silcd/command.c. The router now resolves the client's
1919 information from the server who sent the JOIN command if it
1920 does not know it, and processes the JOIN command only after
1923 * Changed the SilcCommandCb to take new argument; void *context2.
1924 Affected file lib/silccore/silccommand.h
1926 The second argument in the command callbacks in the server now
1927 includes the SilcServerCommandReplyContext if the command was
1928 called as pending command callback from the command reply.
1929 Otherwise it is NULL. When called as pending the status of the
1930 command reply will be checked and if it was erronous the
1931 error will be sent to the original sender of the command.
1932 This way the client always receives the error messages even
1933 though the server was actually the one who received the error
1934 when it resent the command to router, for example. Affected
1935 files silcd/command[_reply].[ch].
1937 * Fixed sending WHOWAS command's error message to client if
1938 the requested client could not be found. It was missing.
1941 * Changed the CMODE and CUMODE commands reply arguments in the
1942 protocol specification. The Channel ID is now sent in both
1943 of the commands to identify the channel. Implemented this
1944 new feature to the client and server. Affected files
1945 lib/silcclient/command_reply.c and silcd/command.c.
1947 * Made better checks for invite and ban lists in the JOIN
1948 command in server. Affected file silcd/command.c.
1950 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1952 * The server now performs the incoming host IP/DNS lookup
1953 using the silc_socket_host_lookup and thus does not block
1954 the server anymore. Affected file silcd/server.c.
1956 * Completed the multi-thread support for SILC Scheduler in
1957 the lib/silcutil/silcschedule.c.
1959 * Fixed the configure.in.pre to detect the pthread correctly
1962 * Fixed a deadlock in silc_task_queue_wakeup in the file
1963 lib/silcutil/silctask.c.
1965 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1967 * Added new function silc_schedule_wakeup that is used in
1968 multi-threaded environment to wakeup the main thread's
1969 schduler. It needs to be used when a thread adds a new task
1970 or removes a task from task queues. After waking up, the
1971 scheduler will detect the task queue changes. If threads
1972 support is not compiled in this function has no effect.
1973 Implemented the wakeup mechanism to both Unix and WIN32
1974 systems. Affected files are lib/silcutil/silcschedule.[ch],
1975 lib/silcutil/unix/silcunixschedule.c and the
1976 lib/silcutil/win32/silcwin32schedule.c.
1978 * Added new function silc_task_queue_wakeup to wakeup the
1979 scheduler by the specified task queue. Affected file
1980 lib/silcutil/silctask.[ch].
1982 * The silc_socket_host_lookup_start now wakes up the scheduler
1983 after adding the timeout task. Affected file is
1984 lib/silcutil/silcsockconn.c.
1986 * The silc_socket_host_lookup is synchronous now if the threads
1987 support is not compiled in. However, the callback is still
1988 called asyncronously through the scheduler, anyway. Affected
1989 file lib/silcutil/silcsockconn.c.
1991 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Added new function silc_socket_host_lookup to perform
1994 asynchronous IP and FQDN lookups for the socket connection.
1995 Affected files lib/silcutil/silcsockconn.[ch].
1997 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1999 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2000 that may or may not compile the mutex support in.
2002 Changed the silc_mutex_alloc interface. It allocates the
2003 mutex now to the sent pointer and returns TRUE or FALSE.
2005 Affected file lib/silcutil/silcmutex.h.
2007 * Wrote the SILC Task Queue interface to support multi-threads.
2008 Affected file lib/silcutil/silctask.[ch].
2010 * Wrote the SILC Scheduler to support multi-threads. Affected
2011 file lib/silcutil/silcschedule.c.
2013 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2015 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2016 in lib/silcutil/win32/.
2018 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * Defined SILC Mutex API and SILC Thread API and implemented
2021 them for Unix. Affected files are
2022 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2023 lib/silcutil/unix/silcunixmutex.c and
2024 lib/silcutil/unix/silcunixthread.c.
2026 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Fixed the silc_server_remove_clients_by_server's channel
2029 key re-generation. The hash table handling was incorrect
2030 and would not work with many channels. Affected file is
2033 * Fixed some memory leaks around the server code.
2035 * Rewrote the silc_server_get_users_on_channel to support IPv6
2036 based Client ID's. Affected file silcd/server.c.
2038 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2039 specification. However, a separate document must be written
2040 to define the detailed signing procedure and the payload
2041 associated with the flag. Defined the flag to the
2042 lib/silccore/silcchannel.h as well.
2044 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Changed the dynamic tables to static size tables in the
2047 lib/silccrypt/silchmac.c.
2049 * Removed GCC dependencies from the code. A patch by cras.
2051 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Do not show the error "Error receiving packet bla bla"
2054 in server if it really was not an error (-2 means that reading
2055 is pending). Affected file silcd/server.c.
2057 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2059 * Fixed a possible crash in silc_server_remove_clients_by_server
2060 in silcd/server.c. Fixed there also some memory leaks.
2062 * Fixed the silc_idlist_replace_client_id. It could replace
2063 wrong key in the hash table. Affected file silcd/idlist.c.
2065 * Do not check whether there are global users on the channel
2066 if the channel->global_users is FALSE. Affected functions
2067 silc_server_remove_from_one_channel and
2068 silc_server_remove_from_channels in silcd/server.c. Also,
2069 do not check if the removed client is local as we can be
2070 sure that global client was not removed from the channel
2071 and checking for global users is not needed.
2073 * The silc_server_remove_clients_by_server now re-generates
2074 the channel keys correctly for those channels that had
2075 clients removed from them. Affected file silcd/server.c.
2077 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Found the reason of random crashes in the server. We weren't
2080 ignoring the SIGPIPE signal (which can be sent in write())
2081 and it crashed the server. Affected file silcd/silcd.c.
2083 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2085 * Assure that sock->user_data is not NULL in the function
2086 silc_server_packet_send in silcd/packet_send.c.
2088 * Disconnect the remote connection if it could not be added
2089 to any ID lists in the server. The affected file is
2092 * Check in silc_server_packet_send[_real/dest] that the
2093 socket is not disconnecting and ignore the data if it is.
2094 Affected file silcd/packet_send.c.
2096 * Define inline to __inline on native WIN32 compilation.
2097 Affected file includes/silcwin32.h.
2099 * Added some explicit type casts for inline code since MSVC
2100 require them. Affected files lib/silcutil/silcbuffer.h,
2101 lib/trq/silcdlist.h and lib/trq/silclist.h.
2103 * Print warning in log files from now on if the packet
2104 decryption fails. Affected file silcd/server.c.
2106 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Changed the `say' client operation's interface to accept
2109 new `type' argument to indicate the type of the message sent
2110 by the library. The application may filter the library's
2111 messages according the type. The affected file is the
2112 lib/silcclient/silcapi.h.
2114 * Added two new functions to lib/silcclient/silcapi.h:
2115 silc_client_del_client and silc_client_del_client_by_id.
2116 Affected file lib/silcclient/idlist.c.
2118 * Moved the clientincludes.h from includes/ to silc/ and
2119 serverincludes.h from includes/ to silcd/.
2121 * The modes for the CMODE and CUMODE are now passed as
2122 uint32 for application with COMMAND_REPLY. The affected
2123 file is lib/silcclient/command_reply.c.
2125 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2127 * /WHOIS without arguments shows client's own information.
2128 Affected file lib/silcclient/command.c.
2130 * Changed PING to not accept any arguments. The specs
2131 says that client can ping only the connected server so
2132 requiring an argument is not needed. Affected file is
2133 lib/silcclient/command.c.
2135 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2137 * Fixed a fatal bug in private message sending and reception
2138 encryption and decryption when using private message keys.
2139 The implementation was incorrect and did not follow the
2140 specification. It causd that some of the message were
2141 lost since it did not use the sending and receiving keys
2142 as the protocol suggests. This has been fixed and will cause
2143 incompatibilities with older clients when sending private
2144 message encrypted with private message keys. Affected files
2145 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2146 and various other in Irssi SILC Client.
2148 Added `responder' boolean argument to the functions
2149 silc_client_add_private_message_key[_ske] to indicate when
2150 the key is added as responder or initiator of the key
2153 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2155 * Removed the silc_ske_check_version function and created
2156 a SilcSKECheckVersion callback. Added also a function
2157 silc_ske_set_callbacks that is now used to set all SKE
2158 callbacks. The callback functions are not given to
2159 the SKE functions anymore, but this function is used to
2162 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2164 * Added `silc_version' argument to the silc_client_alloc
2165 to define the version of the application for the library.
2166 The library will use the version string to compare it
2167 against the remote host's (usually a server) version
2168 string. Affected file lib/silcclient/silcapi.h
2170 * Added the KE protocol context to Key Agreement context
2171 in client library so that we can abort the SKE if it
2172 is in process when we get timeout. Affected file is
2173 lib/silcclient/client_keyagr.c.
2175 * Do not resolve the client ID forever if it returns in the
2176 first time that such client does not exist. This was done
2177 for example with private message. Affected file is
2178 lib/silcclient/client_prvmsg.c.
2180 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2182 * Do not add regex.h for WIN32. The affected file
2183 includes/silcincludes.h.
2185 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2186 not work yet 100%. It generates the DLL's automatically
2187 when compiling with --with-win32 under cygwin.
2189 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2191 * lib/contrib/regex.c is not compiled on WIN32.
2193 * Added silc_net_get_socket_opt function to the
2194 lib/silcutil/silcnet.h.
2196 * Added includes/silcwin32.h for WIN32 specific includes
2199 * Do not use ptime structure or any of the posix process
2200 functions on WIN32 in lib/silccrypt/silrng.c.
2202 * Added silc_gettimeofday to provide generic function
2203 for struct timeval on all platforms. Added the function
2204 to lib/silcutil/silcutil.h.
2206 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2208 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2209 library as they clearly belong there. As a plus side we
2210 can make the actual socket connection routines platform
2213 Added also new generic function silc_socket_read and
2214 silc_socket_write (that used to be silc_packet_[read/write].
2215 The implementation of these are platform specific.
2217 * Added WIN32 specific routines of silc_socket_[read/write]
2218 to lib/silcutil/win32/silcwin32sockconn.c.
2220 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2222 * Added preliminary support for native WIN32 compilation under
2223 cygwin (using the -mno-cygwin option for GCC) to the
2224 ./configure.in.pre. The --with-win32 now prepares the
2225 compilation for native WIN32.
2227 * Rewrote the SILC Scheduler interface in the file
2228 lib/silcutil/silcschedule.h. The scheduler is now context
2229 based and does not have anymore any global static scheduler.
2230 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2231 and created lib/silcutil/win32 directory for WIN32 based
2234 * Added Unix specific network routines to the
2235 lib/silcutil/unix/silcunixnet.c and the old
2236 lib/silcutil/silcnet.c includes now only generic routines.
2238 Added WIN32 specific network routines to the
2239 lib/silcutil/win32/silcwin32net.c.
2241 * Added Unix specific utility functions from the
2242 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2244 * Added WIN32 SILC Scheduler to the file
2245 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2248 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Do not handle JOIN notify in the server if the target client
2251 is not registered (idata->registered == FALSE). The affected
2252 file is silcd/packet_receive.c.
2254 * Update the nickrec->founder in event_cumode in the Irssi SILC
2255 client. Affected file irssi/src/silc/core/silc-channels.c.
2257 * Fixed the CUMODE_CHANGE notify handling in the server when
2258 server and router are announcing their clients on channels.
2259 Now the mode changes are saved and notified correctly. The
2260 affected file is /silcd/packet_receive.c.
2262 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2263 They really did not replace the cache entry in the ID Cache.
2264 Now they do that. Affected file silcd/idlist.c.
2266 * Fixed the KICK notify handling in the Irssi SILC client to
2267 update the channel records so that the kicked client does not
2268 appear to be on the channel. The affected file is
2269 irssi/src/silc/core/silc-channels.c.
2271 * Always update the conn->current_channel when executing command
2272 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2274 * Fixed the KILL notify handling in Irssi SILC client to remove
2275 the killed client on all channels.
2277 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * Fixed the silc_parse_command_line to remove extra spaces
2280 from the start and end of the arguments. Affected file is
2281 lib/silcutil/silcutil.c.
2283 * Cancel and free any active protocol in the function
2284 silc_server_close_connection. Affected file silcd/server.c.
2286 * Cancel and free any active protocol in the function
2287 silc_client_close_connction. Affected file is
2288 lib/silcclient/client.c.
2290 * Do not execute the KILL command for clients that are in
2291 history (ie. they are not in the network). Affected file is
2294 * Fixed KILL notify handling, client does not crash anymore.
2295 Affected file irssi/src/silc/core/silc-channels.c.
2297 * Reduced the default packet buffer size from 2048 to 1024 in
2298 lib/silccore/silcpacket.c.
2300 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2301 counter to the SKE context that is incresed when the SKE library
2302 performs async operation outside the library. If the outside
2303 process frees the SKE context and FREED status will be set
2304 and the library will detect after the sync operation that the
2305 libary is freed. The affected files are
2306 lib/silcske/silcske[_status].[ch].
2308 * Resolve the client entry information in the function
2309 silc_client_channel_message to assure that NULL pointer is not
2310 passed as client entry to the application. */
2312 * Fixed the task timeout calculation to assure that there is
2313 never negative timeouts. The affected file is
2314 lib/silcutil/silcschedule.c.
2316 * Fixed the channel user mode notification sending in server.
2317 It was sent point-to-point to the router (or to server by router)
2318 but it needs to be destined to a channel. The routines now
2319 supports sending the channel user mode notifys to the channels
2320 when announcing clients and channels. Affected files are
2321 silcd/server.c and silcd/packet_receive.c.
2323 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2324 It did not actually replace the old channel entry in the cache.
2325 Affected file lib/silcclient/client_notify.c.
2327 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2329 * Fixed a possible crash in silc_packet_send_prepare. It now
2330 assures always that there is enough space in the buffer and
2331 at the tail area of the buffer (for MAC).
2333 Fixed the inbound buffer reallocation in silc_packet_read.
2334 It was old code and did not handle the reallocation correctly.
2337 The affected file is lib/silccore/silcpacket.c.
2339 * Fixed buffer overflow in silc_parse_nickname in the file
2340 lib/silcutil/silcutil.c.
2342 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2344 * make install generates new server keys only if there is not
2347 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2349 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2350 Added check that if the NOREPLY is set then we will not send
2351 the away message. This avoids infinite loop of away messages
2352 if both clients are away. The affected file is
2353 lib/silcclient/client_prvmsg.c.
2355 * Fixed client crash if /NICK was given without arguments.
2356 Affected file lib/silcclient/command.c.
2358 * Server does not send the invite list in INVITE command back
2359 to the client if the list was not altered. Added this notion
2360 to the protocol spec as well. Affected file silcd/command.c.
2362 Fixed possible crash in INVITE command by checking the
2363 value of silc_server_get_client_route command.
2365 * Fixed the INVITE notify type handling. The arguments are now
2366 taken in correct order and client does not crash. The affected
2367 file is irssi/src/silc/core/silc-channels.c.
2369 Removed the "Inviting xxx to channel" message from the
2370 client library away and let the application handle it.
2371 Affected file lib/silcclient/command.c. Added that message
2372 to Irssi SILC client's message formats.
2374 * Fixed CMODE command crash in client. It now checks the
2375 amount of arguments correctly and does not crash. The affected
2376 file is lib/silcclient/command.c.
2378 * Do not create new channel automatically in silc_channels_join
2379 but check whether the channel by that name already exists.
2380 Affected file irssi/silc/core/silc-channels.c.
2382 * Do not send the SERVER_SIGNOFF to router if the disconnected
2383 entity was the router. Affected file silcd/server.c.
2385 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2386 SILC client as it was missing from there.
2388 Added the handling of the KICK notify to the Irssi SILC client
2389 as it was missing. Added "you have been kicked" message to
2390 Irssi SILC client's message modules formats.
2392 Added the handing of the KILL notify to the Irssi SILC client
2393 as it was missing. Added the kill message module formats
2396 The affected file is irssi/src/silc/core/silc-channels.c.
2398 * The router did not save the channel mode the server announced.
2399 Affected file silcd/packet_receive.c.
2401 * Fixed a possible crash in INFO command in server. If the
2402 server did not provide the server info it crashed. Affected
2403 file silcd/command.c.
2405 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2407 * Fixed the GETKEY command in the server to check also the
2408 global list. Otherwise the GETKEY would not work correctly
2409 in normal SILC server. Affected file silcd/command.c.
2411 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2413 * Fixed GETKEY crash, it crashed if the command did not succseed.
2415 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2417 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2418 is now real and not just an macro interface to GMP.
2420 Removed the entire GMP from the source tree and imported new
2421 NSS MPI library instead. Reason for removing GMP is that it is
2422 extremely large and compiles extremely slow. The NSS MPI
2423 is only a few files and compiles in less than 10 seconds.
2424 The speed is also about the same as GMP. The MPI is imported
2425 to lib/silcmath/mpi.
2427 If the system has GMP installed we will still use the GMP.
2428 If it is not then the NSS MPI will be compiled.
2430 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * Merged a long nickname (127 characters long) crash bugfix from
2433 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2435 * Merged a freed memory reference bugfix from Irssi CVS tree.
2436 Affected file irssi/src/core/commands.c.
2438 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * Added the server's public key sving and verification to the
2441 server when performing the SKE. This was missing and the
2442 remote server's (or router's) public key was accepted without
2443 checking whether we have it previously or trust it at all.
2444 Affected file silcd/protocol.c.
2446 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Check in the silc_server_timeout_remote if protocol is active
2449 and make sure that the protocol's final callback is called so
2450 that all memory if freed. Affected file silcd/server.c.
2452 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * silc_server_whois_send_reply crashed the server if the nickname
2455 was 127 characters long. Affected file silcd/command.c.
2457 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2459 * Added sanity check to the silc_server_new_client. If the hostname
2460 is provided inside username then check that the provided hostname
2461 really is the same as the resolved one. If the hostname was not
2462 resolved then check it from the public key. Affected file is
2463 silcd/packet_receive.c.
2465 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2466 if the server disconnected us and the connection is not valid
2467 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2469 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2470 the library to the lib/silcutil/silcutil.[ch].
2472 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2474 * Close log file after open. Affected file
2475 lib/silcutil/silclog.c.
2477 * Check whether sock == NULL in silc_client_send_packet and return
2478 if it is. Affected file lib/silcclient/silcclient.c.
2480 * Check rec->entry == NULL in the Irssi SILC Client before
2481 sending the channel message. Affecte file is
2482 irssi/src/silc/core/silc-servers.c.
2484 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Merged a splitted window bugfix from Irssi CVS tree. The
2487 affected file is irssi/src/fe-text/textbuffer-view.c.
2489 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2490 It did not print nickname.
2492 * Improved the distributions system a bit.
2494 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2496 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2497 irssi/src/fe-text/gui-window.c.
2499 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2500 to in-active server. The affected file is
2501 irssi/src/silc/core/client_ops.c.
2503 * Resolve the client in USERS command reply if the entry does
2504 not have username resolved. The affected file is
2505 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2506 command to WHOIS command to really resolve stuff. The USERS
2507 is not used any more in any critical section so WHOIS can
2508 be used even though it might be slower than IDENTIFY.
2510 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2513 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * Changed the protocol API a bit more consistent in the
2516 lib/silccore/silcprotocol.[ch].
2518 * Changed the following headers to ROBODoc format:
2520 lib/silccore/silcpayload.h
2521 lib/silccore/silcprotocol.h
2522 lib/silccore/silcsockconn.h
2524 All core library headers are now formatted.
2526 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * Fixed a bug in Irssi SILC client; do not show that you are
2529 server/router operator if you really are not. Affected file is
2530 irssi/src/silc/core/client_ops.c.
2532 * Renamed silc_command_free_payload to silc_command_payload_free.
2533 Affected file lib/silccore/silccommand.h
2535 * Added silcmath.h to include the prototoypes of various routines
2536 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2539 * Changed the following headers to ROBODoc format:
2541 lib/silccore/silcchannel.h
2542 lib/silccore/silccommand.h
2543 lib/silccore/silcid.h
2544 lib/silccore/silcidcache.h
2545 lib/silccore/silcmode.h
2546 lib/silccore/silcnotify.h
2547 lib/silccore/silcpacket.h
2548 lib/silcmath/silcmath.h
2550 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Added checking to the server code not to start the server if
2553 ciphers and stuff are not configured properly. Affected files
2554 silcd/serverconfig.[h] and silcd/server.c.
2556 * Changed the layout of the header files of the public interfaces
2557 in the SILC libraries. The new layout supports ROBODoc
2558 documentation tool (and some others) so that it is easy to create
2559 a library reference manual. All the other headers and source
2560 code must still follow the CodingStyle document. Also source
2561 code must not include these ROBODoc stuffs, only the headers.
2562 Furthermore, all public interface headers must now be named
2563 by using `silc' prefix, example: silcapi.h, silccipher.h.
2564 Some files were renamed due to this. All the other headers
2565 must not be used as public interfaces. I will update the
2566 CodingStyle document later. Changed following headers, so far:
2568 lib/silcclient/silcapi.h
2569 lib/silccore/silcauth.h
2570 lib/silccore/silcprivate.h
2571 lib/silccrypt/silcdh.h
2573 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Removed silc_client_packet_send_flush from the client library
2578 as it is not needed. Affected file lib/silcclient/client.[ch].
2580 * Added printing of message of unresolved authentication method
2581 to the Irssi SILC client. Added it to the module formats.
2582 Removed the same message from the client library.
2584 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Added new distribution feature, DISTLABEL. Every distribution
2587 can define own preprocessor label that can be used in the
2588 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2589 file distributions, acconfig.h.pre and prepare.
2591 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Added Makefile.defines_int to include the actual definitions
2594 for Makefile.defines.in. Tested the new distribution system,
2595 created distributions and tested installation.
2597 * Added AWAY message printing to the Irssi SILC client. Added
2598 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2600 * Added SCONNECT command to call the SILC's CONNECT command.
2601 Cannot use CONNECT directly since Irssi uses that internally.
2602 Affected file irssi/src/silc/core/silc-servers.c.
2604 Added ACTION local command. It is same as ME command but takes
2605 the channel as mandatory argument.
2607 Rewrote some of the Irssi's help files to suite for SILC
2610 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Added Makefile.defines[.in] that should for now on be included
2613 in all Makefile.am file in the source tree. That file includes
2614 all common compilation definitions for SILC source tree.
2616 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Minor changes to the ./prepare script to change the package
2619 name according the distribution name to the configure.in.
2621 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Created new distribution system. Added file `distributions'
2624 that defines all the distributions that can be created out of
2625 the SILC source tree. The ./prepare script now reads that
2626 file to determine how to prepare the distributions. The
2627 first argument to the ./prepare is the name of the distribution
2628 and second is the version of the distribution. If given
2629 without arguments it creates the default (toolkit) distribution
2630 with the default version (defined in ./prepare).
2632 All Makefile.am files that are subject to the distributions
2633 are now named as Makefile.am.pre. These are ./Makefile.am
2634 and lib/Makefile.am. Others may be changed later.
2636 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Added invite list, ban list, some key management and connection
2639 error message printing to module formats in the Irssi SILC client.
2641 * Added new silc_client_set_away_message to set the away message
2642 that is back to the person who sent private message. The
2643 affected file lib/silcclient/silcapi.h and the
2644 lib/silcclient/client_prvmsg.c.
2646 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Fixed the private message sending in the Irssi SILC client,
2649 added local command KEY to the Irssi SILC client.
2651 Added key management and key agreement message formats to the
2652 irssi/src/fe-common/silc/module-formats.[ch].
2654 Added USERS (alias WHO) printing, server/router operator
2655 indication and LIST command printing to the module formats.
2657 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2659 * Fixed channel joining notify handling, cumode notify handling
2660 from Irssi SILC client.
2662 * Added SILC specific module-formats to the Irssi SILC client so
2663 that SILC specific message hilighting, colors etc is possible.
2664 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2666 Added channel mode, channel user mode, actions, notices,
2667 whois and whowas printing to the the module-formats.c.
2669 * Fixed a bug in channel deletion in the server. The channel
2670 is not left to the cache even if the channel founder auth mode
2671 is set when there are no users anymore on the channel. Affected
2672 file silcd/server.c.
2674 * The silc_net_localhost now resolves the entire hostname including
2675 the domain name. Affected file lib/silcutil/silcnet.c.
2677 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Changed the ask_passphrase client operation to be ascynchronous.
2680 It has now a completion callback and a context that the
2681 application must call after it has got the passphrase from
2682 the user. Affected files lib/silcclient/silcapi.h,
2683 lib/silcclient/protocol.c, lib/silcclient/command.c and
2686 Added SilcAskPassphrase callback that the application calls
2687 to deliver the passphrase to the library.
2689 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2690 The public key verification and especially a certificate
2691 verification is asynchronous procedure.
2693 Added new SILC_SKE_STATUS_PENDING status to indicate the
2694 request is pending and a callback will be called to finalize
2697 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2698 indicate that remote end did not send its public key (or
2699 certificate), even though we require it. Added check for this
2700 condition in the SKE. This was a security bug, now fixed.
2702 Defined new SilcSKEVerifyCbCompletion callback that is called
2703 when the verification process is completed.
2705 The affected files lib/silcske/silcske_status.h and
2706 lib/silcske/silcske.[ch].
2708 * Changed the verify_public_key client operation to be async
2709 as well. Defined SilcVerifyPublicKey callback that is used to
2710 indicate the success of the public key verification process.
2712 Changed the server and client to use the new async client
2715 * Changed the Irssi SILC client's internal scheduler to be called
2716 twice as many times as it used to be. As a result the client
2717 should be a bit faster now. Affected file is
2718 irssi/src/silc/core/silc-core.c.
2720 * Added support to Irssi SILC client of asynchronous public key
2721 verification and passphrase inquiry. Affected file is
2722 irssi/src/silc/core/silc-core.c.
2724 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2726 * Do not say "You have left channel %s" in client library.
2727 Moved it to the application. Affected files are
2728 lib/silcclient/command.c and silc/client_ops.c.
2730 * Fixed silc_client_get_clients. Command context was not
2731 duplicated and was freed memory in the callback. Affected
2732 file lib/silcclient/idlist.c.
2734 * Do not say "you are now talking..." on JOIN command in the
2735 client library. The appliation must handle it.
2737 * Do not say ".. changed topic to" in command reply in the
2738 client libary. The application must handle it.
2740 * Fixed TOPIC command sending in the client library.
2742 * Fixed a memory leak in silc_client_command_free in the file
2743 lib/silcclient/command.c.
2745 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * Imported a modified version of Irssi client to the source tree.
2748 The Irssi will be used to create a new client called
2749 Irssi SILC. Imported to irssi/.
2751 Added silc_core_init_finish function to the Irssi. Affected
2752 file irssi/configure.in.
2754 A lot changes in the Makefile.ams around the irssi tree.
2756 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Do not rehash if the new size is same as the old size of the
2759 hash table, in the silc_hash_table_rehash*. The affected file
2760 lib/silcutil/silchashtable.c.
2762 * Replaced hash_table_del_by_context calls from the server
2763 (when channel->user_list and client->channels) to the
2764 hash_table_del as it is sufficient and faster.
2766 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Added silc_hash_table_list, silc_hash_table_get and the
2769 SilcHashTableList structure to provide an alternative way to
2770 traverse the hash table. The affected files are
2771 lib/silcutil/silchashtable.[ch].
2773 * Changed the server's idlist routines to use the hash table
2774 routines to optimize the code.
2776 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2778 * Replaced the client entry's `channel' list and channel entry's
2779 `user_list' list to hash tables for optimized lookup. Changed
2780 the code to use the hash table interface around the code.
2781 Affected file lib/silcd/idlist.[ch].
2783 * Added `auto_rehash' boolean argument to the function
2784 silc_hash_table_alloc to indicate whether the hash table should
2785 auto-rehash when it thinks is appropriate time. It will
2786 increase the hash table size if the there is twice as much
2787 entries in the table than the size of the table, and will
2788 decrease the size if there are twice as less entries than
2789 the size of the table.
2791 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2795 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * silc_idcache_purge_by_context deletes the entry now by context
2798 as it is supposed to do. Affected file lib/silccore/idcache.c.
2800 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2801 client is not anymore valid (WHOWAS givens the info) and not
2802 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2804 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2806 * Removed the `data' and `data_len' arguments from the ID Cache
2807 interfaces and added `name' argument. ID Cache does not handle
2808 anymore the binary data only a names associated with given ID.
2810 * When hashing a Client ID with silc_hash_id the entire ID is
2811 not hashed anymore, instead only the hash of the Client ID is
2812 hashed. This way we can access the Client ID from the cache
2813 with Client ID but with the hash of the ID (which is a hash of
2814 the nickname) as well without any difference in performance.
2816 Added also silc_idcache_find_by_id_one_ext to do one on one
2817 searching when we have the actual ID. Added also function
2818 silc_hash_client_id_compare. The affected files are
2819 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2821 * When hashing the name associated with a ID it is always done
2822 in lowercase. This way we can access the cache without worrying
2823 about case-sensitivity, even though, for example nicknames are
2826 * Fixed a bug in server with channel message sending. It put
2827 wrong ID type as destination ID. The affected file
2828 silcd/packet_send.c.
2830 * silc_idcache_del_by_context now deletes from all hash tables
2831 by context. Affected file lib/silccore/idcache.c.
2833 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2835 * Changed the client library to use the new ID Cache interface.
2836 Changes around the source tree.
2838 * Added silc_hash_table_rehash_ext to rehash with specific
2839 hash function. Affected file lib/silcutil/silchashtable.[ch].
2841 * Added silc_hash_string_compare to compare two strings in the
2842 hash table. Affected file lib/silcutil/silcutil.[ch].
2844 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2846 * Added new function silc_idcache_del_by_context into the
2847 lib/silccore/idcache.[ch].
2849 * Changed the server's ID list routines to use the new ID Cache
2850 interface. Changes around the source tree.
2852 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Added silc_hash_table_del[_by_context]_ext functions in to the
2855 lib/silcutil/silchashtable.[ch].
2857 Removed silc_hash_table_find_all* routines and added new
2858 silc_hash_table_find_foreach to replace them.
2860 Added silc_hash_table_replace_ext function as extended
2861 replacing function. Separated the simple hash table interface
2862 from the extended hash table interface in the file
2863 lib/silcutil/silchashtable.h.
2865 * Fixed minor bugs and changed it to use some of the new
2866 hash table functions in lib/silccore/idcache.c
2868 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Added new function silc_hash_table_find_all to return all keys
2871 in the hash table by the specified key. As the hash table is
2872 collision resistant it also makes it possible to have several
2873 duplicate keys in the hash table. This function may be used to
2874 find all of the keys from the hash.
2876 Added user_context arguments to the SilcHashFunction,
2877 SilcHashCompare and SilcHashDestructor to deliver user specified
2880 Added new fuctions silc_hash_table_find[_all]_ext to do
2881 extended lookup with specified hash and compare functions and
2882 specified user contexts.
2884 Added new function silc_hash_table_add_ext to add the key
2885 with specified hash function and user context.
2887 Added new function silc_hash_table_foreach to traverse all
2888 entrys in the hash table. Added SilcHashForeach callback
2891 Added new function silc_hash_table_del_by_context to delete
2892 the entry only if the context associated with the key matches.
2894 Affected files are lib/silcutil/silchashtable.[ch].
2896 * Removed silc_hash_[server/client/channel]_id and added just
2897 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2898 silc_hash_id_compare to compare two ID's using as the hash table
2899 comparison function. Added also silc_hash_data to hash
2900 binary data and silc_hash_data_compare to compare it.
2902 * Removed silc_idlist_find_client_by_hash as it is not needed
2903 anymore. Affected file silcd/idlist.[ch].
2905 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2906 to use internally the SilcHashTable. The new ID Cache is a lot
2907 faster than the old one. Some of the ID Cache interface was also
2908 rewritten and obsolete and stupid functions were removed.
2910 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * Added entry_count field to the SilcHashTable to keep the number
2913 of the entries in the table. Implemented the function
2914 silc_hash_table_rehash. Added new function
2915 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2917 Fixed a minor bug in silc_hash_table_free.
2919 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2920 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2921 into the lib/silcutil/silcutil.[ch].
2923 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Implemented a collision resistant hash table into the
2926 lib/silcutil/silchashtable[ch]. See the header and the source
2927 for the SilcHashTable API.
2929 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2931 * Merged dotconf version 1.0.2 into lib/dotconf.
2933 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2935 * Do not compile anything in lib/silcsim/* if the SIM support
2936 is not enabled. The tree should now compile without problems
2939 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Compiled the SILC under cygwin. Compiled and tested briefly
2942 without problems. More tests needed. The SIMs didn't compile
2945 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2947 * Fixed possible crash in silc_get_username in the
2948 lib/silcutil/silcutil.c.
2950 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2952 * Fixed a va_arg in silc/client_ops.c.
2954 * Oops, RC5 routines were named AES and caused some problems
2955 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2957 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Added new SilcIDIP structure into the lib/silccore/id.h and
2960 replaced the old `ip' fields from all SILC ID's to that type.
2961 This is a step towards IPv6 support.
2963 The silc_id_get_len takes now the ID as an extra argument.
2964 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2965 both IPv4 and IPv6 based ID's.
2967 The affected files are lib/silccore/id.[ch] and other files
2968 around the tree using these routines.
2970 * Removed the ID length arguments in server from various
2971 silc_server_send_notify_* routines -> they are not needed
2974 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2976 * Fixed memory leak in silc_encode_pem_file in the file
2977 lib/silcutil/silcutil.c.
2979 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2981 * Check minor version as well in the SKE. Affected files are
2982 silcd/protocol.c and lib/silcclient/protocol.c.
2984 * Added --identifier option to the server so that an identifier
2985 can be when creating the public key for the server. Affected
2986 file is silcd/silcd.c.
2988 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2989 lib/silccrypt/silcpkcs.c.
2991 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2993 * Register default ciphers and stuff when using -C option with
2994 the server. Affected file sildc/silcd.c.
2996 * Put back the servers public key filename format, it is better
2997 than the new one. For now, the client keys are saved with the
2998 new filename format. The affected file silc/client_ops.c.
3000 * Implemented the Cipher API for the rest of the ciphers that
3001 did not implement it or implemented it the wrong way.
3003 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Register default ciphers and stuff when using the -S option
3006 in the client. Affected file silc/silc.c. Same also when
3007 creating new key pair with -C option.
3009 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Fixed the silc_verify_public_key client operation function to
3012 save the public keys differently. The fingerprint is now
3013 used as filename and not the hostname. This way also the
3014 client keys are saved uniquely and not with hostnames. The
3015 affected file is silc/client_ops.c.
3017 * Trimmed the silc_hash_fingerprint function to remove extra
3018 whitespaces from the end of the fingerprint. The affected
3019 file is lib/silccrypt/silchash.c.
3023 * Added silc_cipher_register_default function to register all
3024 default ciphers. It can be used when configuration files
3025 does not exist and the application does not want any specific
3026 ciphers in any specific order.
3028 The SilcDList is now used as silc_cipher_list dynamically
3029 allocated cipher list. Removed the static list all together
3030 and now all ciphers must be allocated to the dynamic list.
3031 The silc_cipher_alloc routine was changed to check only the
3034 All silc_cipher_* routines that used to return int returns
3037 The affected files lib/silccrypt/silccrypt.[ch].
3039 * The same thing was done to silc_hash_* as for silc_cipher_*
3040 routines. Affected files lib/silccrypt/silchash.[ch].
3042 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3043 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3044 Added also silc_pkcs_[un]register[_default] functions.
3045 Removed the data_context from the PKCS API.
3047 * Added silc_hmac_register_default function to register default
3048 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3049 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3050 to unregister all hmacs at once.
3052 * Register the default ciphers, hash functions, PKCSs and HMACs
3053 if client's configuration file does not exist. The affected
3056 * The client did not load the hash functions from the SIM
3057 modules at all. Added support for this. Affected file is
3058 silc/clientconfig.c.
3060 * When decoding public key with silc_pkcs_public_key_decode, check
3061 the supported algorithm only if PKCS are registered. Affected
3062 file lib/silccrypt/silcpkcs.c. The same was done with the
3063 silc_pkcs_private_key_decode.
3065 * Fixed the SILC List routines to keep the list always in order.
3066 It used to change the list's order when traversing the list but
3067 not it preserves the order. Affected file lib/trq/silclist.h.
3069 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3071 * Added the client library to use the SilcSocketConnection's
3072 reference counter (by silc_socket_dup) to prevent the bug that
3073 the socket object may be freed underneath async operation.
3075 * The name resolv library checking fixes in the configure.in.pre.
3078 * Created new version of the protocol drafts for future
3079 development. The -03 drafts are the ones that will be changed
3080 in the trunk now and the -02 will remain as they are.
3082 * Send list of CUMODE notifys to the router when announcing
3083 the channel users to the router. Affected file silcd/server.c.
3084 If the router receiving channel founder CUMODE for a channel
3085 that already has channel founder it will send CUMODE notify
3086 to the sender to remove the channel founder rights from the
3087 announced client. Affected file silcd/packet_receive.c.
3089 * The CUMODE notify may now use Server ID as well as the entity
3090 who changes the mode. Updated protocool specs.
3092 * Updated INSTALL and README files.
3094 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * New web pages in the http://silc.pspt.fi. The pages was
3101 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Implemented the [DenyConnectin] config section in the server.
3104 Added silc_server_config_denied_conn to check whether incoming
3105 connection is denied. Affected file silcd/serverconfig.[ch].
3107 * Do not check the ports when checking the incoming configuration
3108 data if the port is 0, meaning any. Affected file is
3109 silcd/serverconfig.c.
3111 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Fixed buffer overflow in silc_string_compare in the file
3114 lib/silcutil/silcutil.c.
3116 * Fixed double free in silc_server_command_leave in the file
3119 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Fixed the version checking in the server. Affected file is
3124 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3126 * Fixed the configuration data fetching when accepting new
3127 connections in the server. Affected file silcd/server.c.
3129 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Added `sender_entry' argument to the function
3132 silc_server_packet_relay_to_channel so that we can check
3133 whether some destination actually belongs to the same route
3134 the sender belongs (ie, we must not resend the packet to the
3135 sender). Affected file silcd/packet_send.[ch].
3137 * Added `servername' field to the SilcClientEntry in the server
3138 to hold the name of the server where client is from. Affected
3139 file is silcd/idlist.h.
3141 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3143 * Moved the channel message encrypting in the router betwen
3144 router connections from silc_server_channel_message to the
3145 silc_server_packet_relay_to_channel since we want to check
3146 whether we have anybody channel before encrypting anything.
3147 Affected files silcd/packet_[receive/send].c.
3149 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Fixed the [AdminConnection] server config section to support
3152 multiple entries. Affected file silcd/serverconfig.c.
3154 * Added support into the server to check the validity of the
3155 incoming connection before executing any KE or authentication
3158 * The connection configuration is now saved to the KE and
3159 connection auth protocol contexts and not fetched anymore in
3160 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3162 * The local hosts listenning address and port is also resolved
3163 now when starting the server. We want to have the socket object
3164 to include the real address and port for the listener. Added
3165 new function silc_net_check_local_by_sock into the files
3166 lib/silcutil/silcnet.[ch].
3168 * Fixed a broadcast bug in server -> do not broadcast if we
3171 * Fixed a routing bug. Do not route broadcast packets ever.
3172 Broadcast packets must be processed always and not routed since
3173 they may be destined to some other host than yourself and thus
3174 would get routed without no good reason. Affected file is
3177 * Added function silc_server_config_is_primary_route to check
3178 whether primary router connection has been configured (a router
3179 configuration that we are initiating). If there is not, we
3180 will assume that there is only two routers in the SILC network
3181 and we will use the incoming router connection as our primary
3182 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3184 * Changed the order of the broadcasting. Broadcast _after_ the
3185 packet has been processed not before. Affected file is
3188 * Fixed a [ClientConnection] parsing bug. The port was never
3189 parsed correctly thus resulting to port 0. Affected file
3190 silcd/serverconfig.c.
3192 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3193 argument and did not set the broadcast packet flag. Affected
3194 file silcd/packet_send.c. Fixed same bug in the function
3195 silc_server_send_notify as well.
3197 * If we receive NEW_ID packet for our own ID in the server, ignore
3200 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3204 * Removed the nickname from the Private Message Payload.
3205 Updated the code and the protocol specs.
3207 * Updated protocol specs for submitting to the IETF.
3209 * Tweaked the Random Number Generator a bit. Affected file
3210 lib/silccrypt/silcrng.c. Exported a new function
3211 silc_rng_[global]_add_noise which can be used to add more
3214 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3216 * Do not parse packets with different timeout when protocol
3217 is active -> may cause problem with rekey. Affected file
3220 * When server receives signoff notify it must not create
3221 new channel key if the client is on any channels since the
3222 sender of the signoff notify will create it.
3224 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3226 * Added printing of error messages during SKE protocol from the
3227 failure packet sent by server during SKE. Affected file
3230 * Removed the client's failure_callback handling with timeout
3231 and handle it immediately when received.
3233 * The SKE library returned wrong type in SUCCESS and FAILURE
3234 packets. They must be 32 bit MSB not 16 bit MSB.
3236 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3238 * Ok, rewrote the logic of the re-key and now it seems to work.
3239 I tested it on high traffic with frequent re-keys without
3240 problems. Added hmac_receive (and renamed hmac to hmac_send)
3241 in SilcClientConnection in lib/silcclient/client.h and
3242 in SilcIDListData in silcd/idlist.h. Also, removed the
3243 SilcPacketParserContext's cipher and hmac fields as they are
3244 not needed anymore and actually caused some problems when
3245 the ciphers and hmac's changed underneath the packet parser.
3247 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * If re-key protocol is active then process the incoming packets
3250 synchronously since we must assure that icoming packets encrypted
3251 with the old key is processed before the new keys is set to
3252 use. This is true other packets than for REKEY packets.
3253 Affected file silcd/server.c. The same was done to client library
3254 as well, affected file lib/silcclient/client.c.
3256 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Fixed bug in client and server to accept the force send if
3259 the packet is send from silc_[server/client]_packet_process
3260 function. Otherwise the packets are never delivered, oops.
3262 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3264 * Disable force sending of packets when REKEY protocol is active.
3265 We must assure that no packet is sent directly when rekey is
3266 performed. All packets must be sent through packet queue.
3267 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3268 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3269 function is silc_[server/client]_packet_send_real to check
3272 * Replaced the SIM paths from example config files to
3273 /usr/local/modules. Also, make install creates now
3274 /usr/local/silc/logs directory to hold all the SILC server
3277 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Made the configure.in.pre work on Solaris. Patch by salo.
3281 * Made all ciphers compatible with non-x86 machines. Defined
3282 CBC mode macros into lib/silccrypt/ciphers_def.h.
3284 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Fixed the make install.
3288 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3290 * When MAC computation fails the silc_packet_decrypt returned 0
3291 even though it was supposed to return -1. Fixed this. The
3292 affected file is lib/silccore/silcpacket.c.
3294 * Do not replace the config files in /etc/silc (in make install)
3295 if they already exist. Affected file ./Makefile.am.
3297 * Do not send re-key packets immediately but through packet queue.
3298 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3300 * Changed silc_net_check_host_by_sock to return FALSE if the
3301 IP/DNS could not be resolved. Though, it returns the IP address
3302 now even if it could not resolve it (but returns also FALSE).
3303 Affected file lib/silcutil/silcnet.[ch].
3305 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Added silc_pkcs_decode_identifier to decode the public key's
3308 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3309 Added also silc_pkcs_free_identifier. Added also new context
3310 SilcPublicKeyIdentifier.
3312 * Added -S option to the silc client. It is used to dump the
3313 contents of the specified public key file.
3315 * Changed the PKCS api to return the public key length when
3316 setting the public key.
3318 * Fixed a fatal bug in the public and private key file loading.
3319 Affected file lib/silccrypt/silcpkcs.c.
3321 * Execute the packet parsing for client with zero (0) timeout
3322 if the protocol is active. Affected file silcd/server.c.
3324 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Made the key generation options to the silcd program. Added
3327 -C option, equivalent to client's option.
3329 * Added new [ServerKeys] config section to the server. It
3330 configures the server's public and private key.
3332 * Defined generic Public Key Payload into the protocol
3333 specification to send specific type of public keys and
3336 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3337 public key or certificate.
3339 * Implemented the GETKEY command to the server and to the
3340 client library and on user interface.
3342 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Made preliminary `make install' work.
3346 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Added SilcServerRekey context into silcd/idlist.h.
3350 * Added the PFS support as defined in the specification to the
3351 SKE protocol. Affected files lib/silcske/*.c.
3353 * Added `ske_group' field to the SilcServerRekey context to hold
3354 the number of the SKE group that is used with PFS in re-key.
3355 Affected file silcd/idlist.h.
3357 * Added PFS re-key support to the server. Affected file is
3360 * Added silc_protocol_cancel to cancel execution of the next
3361 state of the protocol. Affected file is
3362 lib/silccore/silcprotocol.[ch].
3364 * Added the re-key support with and without PFS to the client
3365 library. Re-key is performed once in an hour, by default.
3367 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3368 Added silc_client_rekey_callback and silc_client_rekey_final.
3369 Affected files are lib/silcclient/protocol.[ch] and
3370 lib/silcclient/client.[ch].
3372 * Removed the `hmac_key' and `hmac_key_len' fields from the
3373 SilcClientConnection structure; not needed. Affected file is
3374 lib/silcclient/client.h.
3378 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Do not ask whether user wants to use the negotiated private key
3381 for private messages, just use it. Affected file is
3382 silc/local_command.c.
3384 * Added `send_enc_key' and `enc_key_len' fields to the
3385 SilcIDListData structure since they are needed in the re-key
3386 phase. Affected file is silcd/idlist.[ch].
3388 * Implemented the simple re-key protocol into the server.
3389 Affected files silcd/server.c and silcd/protocol.[ch]. The
3390 re-key will be performed once in an hour, by default.
3392 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3393 Added silc_server_rekey, silc_server_rekey_callback and
3394 silc_server_rekey_final.
3396 * Removed Tunneled flag from the protocol. Updated the code
3397 and the specifications.
3399 * Adde `pfs' field to the SilcIDListData to indicate whether
3400 the PFS is to be performed in the re-key. Affected file is
3403 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3406 int64 of at least the xintXX size. If void * is less that 4
3407 bytes uint32 * will be used. Defined bool as boolean.
3409 * Changed _ALL_ unsigned long and unsigned int to uint32,
3410 unsgined short to uint16 in the source tree.
3412 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3413 not handle clients that has entry->data.registered == FALSE.
3414 They are not in the network anymore. Affected file is
3417 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Implemented the sending of the SERVER_SIGNOFF notify in the
3420 server. Affected file is silcd/server.c.
3422 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3423 Added also silc_notify_payload_encode_args into the
3424 lib/silccore/silcnotify.[ch].
3426 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3427 Affected file silcd/packet_receive.c.
3429 * Implemented the SERVER_SIGNOFF notify handling in the client
3430 library. Affected file lib/silcclient/client_notify.c. Also,
3431 implemnted the printing of the SERVER_SIGNOFF info to the
3432 application. Affected file silc/client_ops.c.
3434 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3435 if the deleting was successful. Affected file silcd/idlist.[ch].
3437 * Added support for public key authentication in the connection
3438 authentication protocol in the client library. Affected file
3439 lib/silcclient/protocol.c.
3441 * Changed the server's silc_idlist_get_clients_by_* interface
3442 to support already allocated array so that new entries may be
3443 added to pre-allocated array. Affected file silcd/idlist.[ch].
3444 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3445 and command replies.
3447 * All command reply functions in the server now calls the
3448 pending command callback even if error occured. This way the
3449 error will be delivered to the client as well. Affected files
3450 silcd/command.c and silcd/command_reply.c.
3452 * Fixed INFO command to return local server's info if no server
3453 was provided. Affected file lib/silcclient/command.c.
3455 * Removed RESTART command for good. Updated the code and the
3458 * Rewrote parts of the task system. It is a bit simpler now.
3459 Removed unsued task priorities. The affected files are
3460 lib/silcutil/silctask.[ch].
3462 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Moved the USERS printing from the library to the application.
3465 Affected files lib/silcclient/command.c and silc/client_ops.c.
3467 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Added channel key re-key support. The re-key is perfomed
3472 only by the router and is done once in an hour. Added `rekey'
3473 field to the SilcChannelEntry in the server. Affected files
3474 silcd/server.c and silcd/idlist.h.
3476 * Added silc_task_unregister_by_context into the file
3477 lib/silcutil/silctask.[ch].
3479 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Added SILC_UMODE_GONE mode to indicate when the client is not
3482 present in the SILC network. Added also support to the local
3483 command AWAY that will set this mode. Added support of showing
3484 "xxx is gone" in WHOIS command. The USERS command shows the
3485 gone status as well.
3487 * Fixed setting server and router operator privileges in the
3488 server's UMODE command. Affected file silcd/command.c.
3490 * Merged the SKE KE1 and KE2 payloads into one payload. The
3491 new KE payload is equivalent to the old KE2 payload.
3493 Cleaned up the SKE Start Payload parsing. It now uses the
3494 simple buffer unformatting to do the parsing. A lot faster
3497 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3498 to the SKE that is used to indicate whether both of the SKE
3499 parties should perform authentication. By default only the
3500 responder performs authentication. By setting this flag also
3501 the initiator must do authentication. By default it is unset
3502 since in normal SKE case, client to server connection, only
3503 the responder should do authentication. When doing SKE between
3504 two clients both should perform authentication. Updated the
3505 code and the protocol specs.
3507 * A little fix to IDENTIFY command in the server. Search the
3508 client first by hash not nickname. Affected file is
3511 * Fixed the silc_client_close_connection to support closing
3512 the client to client connections wihtout deleting too much
3513 data. Affected file lib/silcclient/client.c.
3515 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3516 are received if protocol used to be active but is not anymore
3517 the application would crash due to NULL pointer dereference.
3518 Affected files silcd/server.c and lib/silcclient/client.c.
3520 * Added `hash' field to the SilcClientConnection to include
3521 the hash function negotiated in the SKE protocol.
3523 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3524 to set the channel founder authentication data. A client can
3525 claim the founder rights later by providing the authentication
3526 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3527 This way the channel founder can regain the channel founder
3528 privileges even it is left the channel. This works only on
3529 local server and the client must be connected to the same
3530 server to be able to regain the founder rights. Updated the
3531 protocol specs accordingly.
3533 Added support to the CMODE command in the client to set the
3534 founder auth data. Read the README to see how to set it.
3536 Added support to the CUMODE command to claim the founder
3537 rights. Read the README to see how to do it.
3539 Added support for the founder authentication to the Channel
3540 Entry in the server. Affected file silcd/idlist.h.
3542 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3543 server's CMODE command. Affected file silcd/command.c.
3545 * Added the following new functions into lib/silccore/silcauth.[ch]:
3546 silc_auth_get_method and silc_auth_get_data.
3548 * The server now saves the remote hosts public key to the
3549 SilcIDListData pointer. Affected file silcd/protocol.c.
3551 * The normal server now does not remove the channel entry from
3552 the cache if the founder authentication data is set. It used
3553 to remove it if the founder was the last one on the channel on
3554 the server and left the channel. The auth data is saved and
3555 if the channel is re-joined later the old entry is used with
3556 the old auth data. Affected files silcd/command_reply.c and
3559 * Removed the `pkcs' field from the SilcIDListData structure
3560 in the server; it is not used. Affected file silcd/idlist.h.
3562 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Fixed packet processing on slow links. Partial packets were
3565 never re-processed because the incoming data buffer was cleared
3566 by the application. Application must not directly clear the
3567 sock->inbuf, the packet processing routines handle it. Fixed
3568 this in client library and in server.
3570 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3572 * Fixed the WHOIS and IDENTIFY send reply function to really
3573 check whether to send list or just one entry. Affected file
3576 * Cleaned up the LEAVE command's channel key distribution. The
3577 affected file silcd/command.c.
3579 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3580 can enforce the channel mode as well. In that case the ID
3581 includes the ID of the server. The code now enforces the
3582 mode change if the router have different mode than the server.
3584 * The notify client operation with CMODE_CHANGE notify can now
3585 return NULL client_entry pointer if the CMODE was not changed
3586 by client. Application must check for this.
3588 * Added <Server ID> argument to INFO command to support server
3589 info fetching by Server ID.
3591 * Added silc_server_announce_get_channel_users to get assembled
3592 packets of channel users of the specified channel. Affected
3593 file silcd/server.[ch].
3595 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3596 was freed underneath the ID Cache.
3598 * Re-announce clients when the server received CHANNEL_CHANGE
3599 notify from the router. Affected file silcd/packet_send.c.
3601 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3604 crashed since it did not handle the fact that there is no cipher
3605 called "3" and didn't check the error condition. Now fixed.
3607 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3608 flag. It can be used to send message requests.
3610 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * Implemented the RESTART command in the client.
3614 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3615 notice type messages. Added notice printing to the user
3618 * The channel keys are not re-generated if the channel's mode
3619 is PRIVKEY, ie private key on the channel exists. Affected
3620 files silcd/server.c and silcd/command.c.
3622 * Fixed a little bug in channel message delivery when channel
3623 private keys are set in the server. Affected file is
3624 silcd/packet_send.c.
3626 * Changed the setting on channel->on_channel = TRUE from the
3627 silc_client_save_channel_key to the JOIN command reply. The
3628 key payload is not received if the private channel key is set.
3629 Affected file lib/silcclient/command_reply.c and the
3630 lib/silcclient/client_channel.c.
3632 * When the CMODE_CHANGE notify is sent and the channel private
3633 key mode is removed the channel key must be re-generated in
3634 other cells as well. Added this support for the router in the
3635 silcd/packet_receive.c.
3637 * Added new local command NOTICE to send notice message on
3638 channel. Affected file silc/local_command.[ch].
3640 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Added new local command ME to the client. It is used to send
3643 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3644 some action. Affected file silc/local_command.[ch].
3646 * Changed channel_message and private_message client operations
3647 to deliver the message flags to the application. Added also
3648 the `flags' arguments to the silc_client_send_channel_message
3649 and silc_client_send_private_message functions. Affected file
3652 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Redefined the Private Message Payload to support private message
3655 keys and to support the new private message flags. Updated
3656 the protocol specs. Flags makes it possible to have for example
3657 CTCP style messages.
3659 * Added new type SilcPrivateMessagePayload and defined an API
3660 for it in the lib/silcclient/silcprivate.[ch].
3662 * Tested private message private keys successfully. Tested the
3663 private message key set, unset and list commands with the new
3666 * Redefined the Channel Message Payload to include the channel
3667 message flags (equal with private message flags) to support
3668 for example CTCP style messages.
3670 * Defined some of the message (for channel and private message)
3671 flags. Updated the protocol specs and added the flags to the
3672 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3674 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Added SilcKeyAgreementStatus type to the key agreement routines
3677 to indicate the current status and error if one occured.
3678 The status types are defined in the lib/silcclient/silcapi.h.
3680 * Added new local command KEY that is used to set and unset private
3681 keys for channels, set and unset private keys for private messages
3682 with remote clients and to send key agreement requests and
3683 negotiate the key agreement protocol with remote client. The
3684 key agreement is supported only to negotiate private message keys,
3685 it currently cannot be used to negotiate private keys for channels,
3686 as it is not convenient for that purpose.
3688 * Fixed a minor pending callback setting bug in the function
3689 silc_client_get_client_by_id_resolve, now the function works.
3690 Affected file lib/silcclient/idlist.c.
3692 * Added function silc_net_get_local_port to get local bound
3693 port by socket. Added to lib/silcutil/silcnet.[ch].
3695 * Added `sockets' and `sockets_count' fields to the SilcClient
3696 object. They hold the sockets of the listenning sockets in
3697 the client. Listenning sockets may be for example the key
3698 agreement server. Affected file lib/silcclient/client.[ch].
3699 Added functions the silc_client_add_socket and the
3700 silc_client_del_socket. They are exported to the application
3703 * Added ~./silc/clientkeys to support other client's public keys.
3705 * Renamed verify_server_key client operation to verify_public_key
3706 and added one argument to indicate the type of the connection
3707 (server, client etc.).
3709 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * Added silc_server_connection_auth_request to handle the
3712 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3713 silcd/packet_receive.[ch].
3715 * Added silc_server_send_connection_auth_request into the
3716 silcd/packet_send.c to send the connection auth request packet.
3718 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3721 * Fixed the public key authentication in responder side in the
3722 server. The `auth_data' pointer includes the SilcPublicKey
3723 not the path to the public key. Affected file silcd/protocol.c.
3725 * Implemented the public key authentication in the initiator side
3726 in the server. Affected file silcd/protocol.c.
3728 * Removed the [RedirectClient] config section from the server
3729 configuration. Is not needed and I don't want to implement it.
3731 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Cleaned up the CMODE command in the server. It now works
3734 correctly and supports all the modes defined in the protocol.
3735 Affected file is silcd/command.c.
3737 * Added `hmac_name' field to the SilcChannelEntry in the server
3738 to hold the default HMAC of the channel. It can be set when
3739 creating the channel (with JOIN command). Affected files
3742 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3743 type to indicate the change of the current cipher and hmac
3744 on the channel. Client can safely ignore the <cipher> argument
3745 (if it chooses to do so) since the CHANNEL_KEY packet will
3746 force the channel key change anyway. The <hmac> argument is
3747 important since the client is responsible of setting the new
3748 HMAC and the hmac key into use.
3750 * Fixed the CMODE command in the client library as well.
3752 * Tested CMODE command in router environment successfully.
3754 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * Show the version of the remote client (or server) when connecting
3757 to the server. It is logged to the log file. Affected file
3758 is silcd/protocol.c.
3760 * Fixed the KILLED notify handling in the client library. The
3761 client must be removed from all channels when receiving the
3764 Also, do not remove the client entry when giving the KILL
3765 command but when the KILLED notify is received.
3767 * Removed silc_idlist_find_client_by_nickname from the server.
3768 Not needed anymore. Affected files silcd/idlist.[ch].
3770 * Implemented the CHANNEL_CHANGE notify type handling to the
3771 server. Affected file silcd/server.c.
3775 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Added silc_server_send_notify_invite to send the INVITE
3778 notify between routers.
3780 * Implemented the INVITE command correctly to the server.
3782 * Implemented the INVITE notify type handling in the server.
3784 * Implemented the INVITE command to the client library and on the
3787 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Added function silc_server_get_client_resolve to find the
3790 client entry by ID from all ID lists and then resolve it
3791 (using WHOIS) if it cannot be found. Affected file is
3794 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Implemented the BAN command to the client library.
3798 * The JOIN command in the server now checks the invite list
3801 * Changed the silc_command_reply_payload_encode_va and the
3802 silc_command_payload_encode_va to support that if argument is
3803 NULL it ignores and checks the next argument. Affected file
3804 lib/silccore/silccommand.c.
3806 * Added silc_server_send_notify_ban to send the BAN notify
3807 type between routers.
3809 * Chaned the silc_notify_payload_encode to support that if
3810 argument is NULL it ignores and checks the next argument.
3811 Affected file lib/silccore/silcnotify.c.
3813 * Tested ban lists in router environment successfully.
3815 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Implemented BAN command to the server, in silcd/command.[ch].
3819 * Removed the BAN and INVITE_LIST modes from the CMODE command
3822 * Added function silc_string_match to regex match two strings.
3823 Affected files lib/silcutil/silcutil.[ch].
3825 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Redefined parts of the SilcChannelEntry in the server to support
3828 the new ban and invite lists.
3830 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Redefined the INVITE command. The same command can be used to
3833 invite individuals to the channel but also to manage the invite
3834 list of the channel (to add to and remove from the invite list).
3835 Updated the protocol specs.
3837 * Added new command SILC_COMMAND_BAN that can be used to manage
3838 the ban list of the channel. Updated the protocol specs.
3840 * Removed the channel modes: the SILC_CMODE_BAN and the
3841 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3842 in the CMODE command. The equivalent features are now available
3843 using INVITE and BAN commands. Updated the protocol specs.
3845 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3846 in the network about change in the current ban list. The notify
3847 type is not used by the client.
3849 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3850 support the invite lists.
3852 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3854 * Added new function silc_string_regexify that converts string
3855 including wildcard characters into regex string that can
3856 be used by the GNU regex library. Added into the file
3857 lib/silcutil/silcutil.[ch].
3859 Added silc_string_regex_combine to combine to regex strings
3860 into one so that they can be used as one regex string by
3861 the GNU regex library. Added into the file
3862 lib/silcutil/silcutil.[ch].
3864 Added silc_string_regex_match to match two strings. It returns
3865 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3867 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Imported GNU regex to the soruce tree into lib/contrib.
3870 Fixed some compiler warning from the regex.c.
3872 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Fixed MOTD command in the server to work in router environment.
3876 * Fixed the MOTD command in the client library to support
3877 the server argument in the command.
3879 * Added `nickname_len' argument to the silc_idlist_add_client
3880 in the server, as the `nickname' argument may be binary data
3883 * Added silc_idlist_get_channels to return all channels from
3886 * Implemented LIST command to the server. Affected file is
3889 * Implemented the LIST command to the client library and on the
3892 * Added [<user count>] argument to the LIST command reply.
3893 With private channels the user count is not shown.
3895 * Updated TODO and README.
3897 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * The client entry's data.registered must be TRUE even with
3900 global client entry on global client list. The data.registered
3901 is used to check whether the client is anymore in the network,
3902 for example with WHOWAS command so it must be valid.
3904 * Fixed the WHOWAS command in the server. It now actually works
3905 in router environment. Added function into silcd/command_reply.c
3906 silc_server_command_reply_whowas_save.
3908 * Added silc_idlist_purge function to the silcd/idlist.c
3909 to periodically purge the ID Cache.
3911 * Fixed INFO command in the server. It works now in router
3912 environment. Added <server name> argument to the INFO command
3913 reply. Updated the protocol specs.
3915 * Fixed minor bug in silc_idcache_purge to not purge if the
3916 expire value is zero.
3918 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3919 they were buggy because of the WHOWAS information.
3921 * Fixed local command MSG to handle the async resolving of
3922 the remote client properly. It used to fail the first MSG.
3923 Affected file silc/local_command.c.
3925 * Added `data_len' field to SilcIDCache context.
3927 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Update TODO. Todo in commands in the server.
3931 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3934 used by routers as broadcast packet to inform other routers
3935 about the changed user mode.
3937 Implemented the notify handling in the server. Affected file is
3938 silcd/packet_receive.c. Added the function
3939 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3941 * Added new generic Channel Payload and deprecated the New Channel
3942 Payload. The New Channel Payload is now the generic Channel
3945 * Added new argument `mode' to the silc_server_send_new_channel
3946 as it is required in the Channel Payload now.
3948 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3949 and created a new and real SilChannelPayload to represent the
3950 new generic Channel Payload. Implemented the encode/decode
3951 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3953 * Added silc_server_get_client_channel_list to return the list
3954 of channels the client has joined for WHOIS command reply.
3955 Affected file silcd/server.[ch].
3957 * Implemented the channel list sending in the WHOIS command reply
3958 in server and in the client.
3960 Implemented the channel list displaying on the user interface
3961 as well. Affected file silc/client_ops.c.
3963 * Added silc_channel_payload_parse_list to parse list of Channel
3964 Payloads. It returns SilcDList list of SilcChannelPayloads.
3965 Client for example can use this function to parse the list of
3966 channels it receives in the WHOIS command reply. The caller
3967 must free the list by calling silc_channel_payload_list_free.
3968 Affected files lib/silccore/silcchannel.[ch].
3970 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3972 * Added one new argument <user mode> to the WHOIS command reply
3973 to return the mode of the user in SILC. Updated the protocol
3976 Implemented it to the server and client.
3978 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Fixed the mode printing on the user interface on joining.
3981 Affected file silc/client_ops.c.
3983 * Implemented the UMODE command and user modes in general to the
3984 client library and to the user interface.
3986 * Implemented the UMODE command to the server.
3988 * The server now sends UNKNOWN_COMMAND error status if client sends
3989 unknown command. Affected file silcd/command.c.
3991 * All server commands now handle the command identifier the right
3992 way when sending the command reply to the client. The client can
3993 use to identify the command replies with the identifier.
3995 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Added silc_server_get_client_route to resolve the route to
3998 the client indicated by the client ID. Affected file is
4001 * Added silc_server_relay_packet as general function to relay
4002 packet to arbitrary destination. This deprecates functions
4003 like _send_private_message_key, _relay_notify etc. Affected
4004 file is silcd/packet_send.[ch].
4006 Removed silc_server_send_key_agreement,
4007 silc_server_send_private_message_key and
4008 silc_server_packet_relay_notify functions from the file
4009 silcd/packet_send.[ch].
4013 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4014 server. Affected file silcd/packet_receive.[ch].
4016 * Implemented the KILL command to the client. Implemented the
4017 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4018 Affected files lib/silcclient/command[_reply].c and
4019 lib/silcclient/client_notify.c. Implemented the KILL notify
4020 printing in the user inteface.
4022 * Fixed a lot silc_parse_nick memory leaks from the client
4023 library in the file lib/silcclient/command.c.
4025 * Changed the silc_server_send_notify_on_channels's `sender'
4026 argument from SilcSocketConnection to SilcClientEntry to
4027 check the sender as entry and not as connection object and not
4028 to send to the client provided as argument. The affected file
4029 is silcd/packet_send.[ch].
4031 * The notify packets that are destined directly to the client used
4032 to not to be processed by the server. Now changed that and the
4033 server processes all notify packets. After relaying the packet
4034 to the client the notify packet is processed in the server.
4036 * The silc_server_free_client_data now checks whether there is
4037 pending outgoing traffic for the client and purges the data to
4038 the network before removing the client entry.
4040 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4043 an client is killed from the SILC Network. Updated the protocol
4046 Added new function silc_server_send_notify_killed to the
4047 silcd/packet_send.[ch].
4049 * Added function silc_server_packet_relay_notify to relay notify
4050 packets that are destined directly to a client. In this case
4051 the server does not process the notify packets but merely relays
4052 it to the client. Affected file silcd/packet_send.[ch].
4054 Added also silc_server_packet_process_relay_notify to check
4055 whereto relay the notify. Affected file is
4056 silcd/packet_receive.[ch].
4058 * Implemented the KILL command to the server.
4062 * Added the backup schema desgined last fall to the protocol
4063 specs for everyone to see. The specification is in the
4064 *-spec-xx.txt draft and the packet type definitions for the
4065 backup routers is in *-pp-xx.txt draft. Thusly, added also
4066 new packet type SILC_PACKET_CELL_ROUTERS.
4068 * A big security problem in the implementation discovered. The
4069 signoff of an client did not cause new channel key generation
4070 which it of course should've done. The channel keys must be
4071 always re-generated when client leaves (or signoffs) the channel.
4072 The silc_server_remove_from_channels funtion now handles
4073 the channel key re-generation.
4075 * Added `sender' argument to the silc_server_send_notify_on_channels
4076 to not to send the client provided as argument. Affected file
4077 silcd/packet_send.[ch].
4079 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4081 * Implemented OPER and SILCOPER commands into the server and
4084 * Added silc_auth_verify and silc_auth_verify_data to verify
4085 the authentication directly from the authentication payload.
4086 It supports verifying both passphrase and public key based
4087 authentication. Affected file lib/silccore/silcauth.[ch].
4089 * Added `hash' field to the SilcIDListData structure. It is the
4090 hash negotiated in the SKE protocol. Affected file is
4093 * Slight redesigning of the SilcAuthPayload handling routines.
4094 Do not send SilcPKCS but SilcPublicKey as argument.
4096 * Implemented the public key authentication support to the
4097 serverconfig. The public key is loaded from the provided path
4098 and saved as authentication data to void * pointer. Thus,
4099 changed the unsigned char *auth_data to void *auth_data;
4101 * Fixed SHUTDOWN command to send the reply before the server
4102 is shutdown. :) Affected file silcd/command.c.
4104 * Fixed fatal bug in CONNECT command. The hostname was invalid
4105 memory and server crashed. Affected file silcd/command.c.
4107 * Fixed fatal bug in CLOSE command. The server_entry became
4108 invalid but was referenced later in the command. Affected file
4111 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Fixed fatal bug in failure packet handling. Server ignored
4114 the failure and thus crashed when it came.
4118 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4121 that the command may be executed only once in (about) 2 seconds.
4122 The old SILC_CF_LAG flag is same but allows command bursts up
4123 to five before limiting.
4125 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4126 server code. Various commands now includes the CF_LAG_STRICT
4127 flag to disallow any kind of miss-use of the command.
4129 * Fixed the silc_buffer_unformat to not to allocate any data
4130 if the length of the data is zero. It used to allocate the
4131 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4133 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Changed the format of AdminConnection configuration section
4136 in the server. Added username of the admin to the format.
4137 Affected files silcd/serverconfig.[ch].
4139 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4140 to return admin configuration data by host, username and/or
4143 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Implemented WHOWAS command to the server. Added the functions:
4147 silc_server_command_whowas_parse,
4148 silc_server_command_whowas_send_reply,
4149 silc_server_command_whowas_from_client and
4150 silc_server_command_whowas_from_server
4152 * Added <Client ID> argument to the WHOWAS command reply. Updated
4153 the protocol specs accordingly.
4155 * Implemented WHOWAS command and command_reply to the client
4158 Implemented the WHOWAS printing on the user interface.
4160 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Added new argument to the WHOWAS command reply, the real name.
4163 It is an optional argument. Updated the protocol specs.
4165 * Added SilcIDCacheDestructor callback that is registered when
4166 the SilcIDCache is allocated. The callback is called when
4167 an cache entry in the ID Cache expires, or is purged from the
4168 cache. Added into lib/silccore/idcache.[ch].
4170 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4171 to destruct the client entries when the cache entry expires.
4172 Other ID Cache's in server and in the client library ignores
4175 * If the ID Cache entry's `expire' field is zero then the entry
4176 never expires. Added boolean `expire' argument to the
4177 silc_idcache_add function in the lib/silccore/idcache.[ch].
4178 If it is TRUE the default expiry value is used.
4180 * Added silc_server_free_client_data_timeout that is registered
4181 when client disconnects. By default for 5 minutes we preserve
4182 the client entry for history - for WHOWAS command.
4184 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Added support to the server to enforce that commands are not
4187 executed more than once in 2 seconds. If server receives
4188 commands from client more frequently, timeout is registered
4189 to process the commands. Affected file silcd/command.c.
4190 Added new function silc_server_command_process_timeout.
4192 * Changed NICK_NOTIFY handling in client library to check that
4193 if the client's nickname was changed, so there is no need to
4194 resolve anything from the server.
4196 * Removed error printing from the WHOIS and IDENTIFY commands.
4197 If error occurs then it is ignored silently in the client library.
4198 The application, however, may map the received error to
4199 human readable error string. The application currently maps
4200 the NO_SUCH_NICKNAME error to string.
4202 * Made the command status message public to the application. Moved
4203 them from lib/silcclient/command_reply.c to
4204 lib/silcclient/command_reply.h. The application can map the
4205 received command status to the string with the
4206 silc_client_command_status_message function.
4208 * Added check to the server to check that client's ID is same
4209 as the Source ID in the packet the client sent. They must
4212 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Added dist-bzip hook to the Makefile.am to make bzip2
4215 compressed distributions.
4217 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4219 * Server now enforces the maximum length for the nickname and
4220 the channel as protocol specification dictates. 128 bytes for
4221 nickname and 256 bytes for channel name.
4223 * Moved the WHOIS printing to the application. The client libary
4224 does not print out the WHOIS information anymore, the application
4225 must do it. Renamed silc_client_command_reply_whois_print to
4226 the silc_client_command_reply_whois_save.
4228 The client's idle time is also sent to the application now, and
4229 the idle is shown on screen.
4231 * Added silc_client_command_reply_identify_save to save the
4232 received IDENTIFY entries.
4234 * Do not check for channel private keys in message sending and
4235 reception if the channel does not have the PRIVKEY mode set.
4236 Affected file lib/silclient/client_channel.c.
4238 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4241 just surfaced after chaning the JOIN procedure.
4243 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Added silc_client_get_clients_by_list to get client entries
4246 from Client ID list, that is returned for example by JOIN
4247 and USERS command replies. The application should use this
4248 function for example when JOIN command reply is received to
4249 resolve the clients already on the channel (library does not
4250 do that anymore as USERS command reply is not used in the JOIN
4251 procedure anymore). Affected files lib/silcclient/silcapi.h and
4252 lib/silcclient/idlist.c.
4254 * JOIN command reply and USERS command reply returns now SilcBuffer
4255 pointers instead of unsigned char pointers when returning
4256 the client list and mode list.
4258 * Added <Client ID> argument to the JOIN command reply, mainly
4259 for the server to identify for which client the command was
4260 originally sent. Updated protocol specs accordingly.
4262 * Added SilcDlist private_key pointer to the SilcChannelEntry
4263 in the client to support the channel private keys. Affected
4264 file is lib/silcclient/idlist.h.
4266 * Added SilcChannelPrivateKey argument to the function
4267 silc_client_send_channel_message so that application can choose
4268 to use specific private ke if it wants to. If it is not provided,
4269 the normal channel key is used, unless private keys are set.
4270 In this case the first (key that was added first) is used
4271 as the encryption key.
4273 * Implemented the support for channel private key handling.
4274 Implemented the following functions:
4276 silc_client_add_channel_private_key,
4277 silc_client_del_channel_private_keys,
4278 silc_client_del_channel_private_key,
4279 silc_client_list_channel_private_keys and
4280 silc_client_free_channel_private_keys
4282 Affected file lib/silcclient/client_channel.c.
4284 * Added the support for the private keys in the channel message
4285 sending and encryption and in the message reception and
4286 decryption. Affected funtions are
4287 silc_client_send_channel_message and silc_client_channel_message.
4289 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Added SKE's key verify callback to the client library's
4292 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4294 * Removed the statement that server (or router) must send USERS
4295 command reply when joining to the channel so that the client
4296 knows who are on the channel. Instead, the client list and
4297 client's mode list is now sent in the JOIN command reply to the
4298 client who joined channel. This is better solution.
4300 * Added function silc_server_get_users_on_channel and function
4301 silc_server_save_users_on_channel to the silcd/server.[ch].
4303 * Removed function silc_server_command_send_users from the
4306 * Do not show topic on the client library anymore. The topic is
4307 sent in the command reply notify to the application and the
4308 application must show the topic now.
4310 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Added client searching by nickname hash into the IDENTIFY and
4313 WHOIS commands in the server as they were clearly missing from
4314 them. Affected file is silcd/command.c.
4316 * Fixed a bug in private message receiving in the client library.
4317 The remote ID was freed and it wasn't supposed, now it is
4320 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Minor fix to the channel payload; allocate the data area, as it
4323 needs to be of specific length.
4325 * If the key agreement port is zero then the operating
4326 system will define the bound port. Affected files are
4327 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4329 * Added new function silc_channel_payload_decrypt into the file
4330 lib/silccore/silcchannel.[ch].
4332 * Moved the channel message etc, check from silc_packet_decrypt
4333 to applications. The library calls now a generic
4334 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4335 when the packet is either normal or special. This was done to
4336 allow more wide range of checking that was not allowed when
4337 the code was in library. Now applications can do virtually any
4338 checks to the packet and return to the library the decision how
4339 the packet should be processed. Affected files are
4340 lib/silccore/silcpacket.[ch].
4342 Added silc_server_packet_decrypt_check to the server and
4343 silc_client_packet_decrypt_check to the client library.
4345 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4346 to send with specified source and destination information.
4348 * Channel message delivery between routers was broken after the
4349 channel key distribution was fixed earlier. The channel key
4350 was used be to distributed to other routers as well which is not
4351 allowed by the protocol. Now this is fixed and channel keys
4352 really are cell specific and the channel message delivery between
4353 routers comply with the protocol specification.
4355 * Fixed various commands in server to check also the global list
4356 for the channel entry and not just the local list. The affected
4357 file silcd/command.c.
4359 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Added assert()s to buffer formatting and unformatting routines
4362 to assert (if --enable-debug) when error occurs. Affected
4363 file: lib/silcutil/silcbuffmt.c.
4365 * Changed to auto-reconnect to check whether the remote host is
4366 router and register the re-connect timeout if it is. It used
4367 to check that whether we are normal server, but router must do
4368 auto-reconnect with another router as well. Affected file
4371 * Removed the [<key len>] option from CMODE command as the cipher
4372 name decides the key length, nowadays. See the defined ciphers
4373 from the protocol specification.
4375 * Added [<hmac>] option to the CMODE command to define the HMAC
4376 for the channel. Added SILC_CMODE_HMAC channel mode.
4378 * Added [<hmac>] option for the JOIN command so that user can
4379 select which HMAC is used to compute the MACs of the channel
4382 * Added Hmac field to the Channel Message Payload. The integrity
4383 of plaintext channel messages are now protected by computing
4384 MAC of the message and attaching the MAC to the payload. The
4385 MAC is encrypted. Now, it is clear that this causes some
4386 overhead to the size of the packet but rationale for this is that
4387 now the receiver can verify whether the channel message decrypted
4388 correctly and also when private keys are set for the channel the
4389 receiver can decrypt the packet with several keys and check from
4390 the MAC which key decrypted the message correctly.
4392 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4393 lib/silccrypt/silccipher.[ch].
4395 * Added silc_hash_len to return the digest length into the
4396 lib/silcrypt/silchash.[ch].
4398 * Rewrote parts of Silc Channel Payload interface in the
4399 lib/silccore/silcchannel.[ch]. The encode function now also
4400 encrypts the packet and parse function decrypts it.
4402 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4404 * Fixed a minor formatting bug in the SKE's key material processing.
4405 It actually might have processed the keys wrong way resulting
4408 * Redefined the mandatory HMAC algorithms and added new algorithms.
4409 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4410 and hmac-md5 truncated to 96 bits. The mandatory is now
4411 hmac-sha1-96. Rest are optional (including the one that used
4412 to be mandatory). Rationale for this is that the truncated HMAC
4413 length is sufficient from security point of view and can actually
4414 make the attack against the HMAC harder. Also, the truncated
4415 HMAC causes less overhead to the packets. See the RFC2104 for
4418 * Added new [hmac] configuration section. The SKE used to use
4419 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4420 is of course wrong. The official names that must be proposed in
4421 the SKE are the ones defined in the protocol specification
4422 (hmac-sha1-96 for example). The user can configure any hmac
4423 using any hash function configured in the [hash] section. At
4424 least, the mandatory must be configured.
4426 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4428 * Added HMAC list to the SKE proposal list. It has now both
4429 hash algorithm list and HMAC list. This makes the protocol
4430 incompatible with previous versions. The SKE now seems to work
4431 the way it is supposed to work, for the first time actually.
4433 * Defined plain Hash algorithms to the protocol specification.
4436 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Implemented support for key agreement packets into the server.
4439 Added functions silc_server_key_agreement and
4440 silc_server_send_key_agreement. Other than these functions,
4441 server has nothing to do with this packet.
4443 * Added support for private message key packets into the server.
4444 Added functions silc_server_private_message_key and
4445 silc_server_send_private_message_key.
4449 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4450 called in the protocol's final callback instead in the END
4451 protocol state. This makes a little more sense and in the same
4452 time in client we can use the same protocol routines for normal
4453 key exchange and to key agreement packet handling as well.
4455 * Added to both client's and server's KE protocol context the
4456 SilcSKEKeyMaterial pointer to save the key material. We will
4457 bring the key material to the protocol's final callback by doing
4458 this. The final callback must free the key material.
4460 * Added SKE's packet_send callback into client's KE protocol
4461 context so that the caller can choose what packet sending function
4462 is used. This way we can use different packet sending when
4463 doing normal SKE when doing key agreement packet handling (in
4464 the key agreement packet handling we do not want to encrypt
4467 * Implemented the responder side of the key agreement routines
4468 in the client. The client can now bind to specified port and
4469 accept incoming key negotiation. The key material is passed
4470 to the application after the protocol is over.
4472 * Implemented the processing of incoming Key Agreement packet
4473 in the client. Added function silc_client_key_agreement to
4476 * Implemented the intiator side of the key agreement routines
4477 in the client. The client can now initiate key agreement with
4478 another remote client. The key material is passed to the
4479 application after the protocol is over.
4481 * Created client_keyagr.c to include all the key agreement
4484 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4485 SILC_TASK_CALLBACK except that it is not static.
4487 * Created client_notify.c and moved the Notify packet handling
4488 from the client.[ch] into that file.
4490 * Created client_prvmsg.c and moved all private message and
4491 private message key routines from the client.[ch] into that file.
4493 * Create client_channel.c and moved all channel message and
4494 channel private key routines from the client.[ch] into that file.
4496 * Changed silc_client_get_client_by_id_resolve to resolve with
4497 WHOIS command instead of IDENTIFY command, in the file
4498 lib/silclient/idlist.c.
4500 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Implemented the SKE's responder side to the Client library.
4504 * When FAILURE is received to the protocol do not trust it
4505 blindly. Register a timeout to wait whether the remote closes
4506 the connection as it should do it, only after that process the
4507 actual failure. This was changed to both client and server.
4509 * Added client_internal.h to include some of the structures
4510 there instead of client.h in lib/silcclient/.
4512 * Added function silc_task_unregister_by_callback to unregister
4513 timeouts by the callback function.
4515 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Some "Incomplete WHOIS info" errors has been appearing on the
4518 log files. Took away the entry->userinfo check from WHOIS
4519 reply sending. The entry->userinfo is now " " if client did not
4520 provide one. I thought this was fixed earlier but something
4521 is wrong still. Let's see if the error still appears.
4523 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Fixed a minor bug in the login when the channel key is
4526 re-generated in the server. It used to generate the key in
4527 wrong order and thus caused problems in the channel traffic.
4529 * Fixed a minor bug in channel key distsribution after
4530 KICK command. The key was not sent to the router even though
4533 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4535 * Added silc_ske_process_key_material_data as generic routine
4536 to process any key material as the SILC protocol dictates. The
4537 function is used by the actual SKE library but can be used by
4538 applications as well. This relates to the private message keys
4539 and the channel private keys since they must be processed the
4540 same way the normal SILC session keys. The protocol dictates
4541 this. Affected files: lib/silcske/silcske.[ch].
4543 Added also silc_ske_free_key_material to free the
4544 SilcSKEKeyMaterial structure.
4546 * Defined silc_cipher_set_key function to set the key for
4547 cipher without using the object's method function. The affected
4548 files: lib/silccrypt/silccipher.[ch].
4550 * Implemented silc silc_client_add_private_message_key,
4551 silc_client_add_private_message_key_ske,
4552 silc_client_del_private_message_key,
4553 silc_client_list_private_message_keys and
4554 silc_client_free_private_message_keys functions in the
4557 Added functions silc_client_send_private_message_key to send
4558 the Private Message Key payload and silc_client_private_message_key
4559 to handle incoming Private Message Key payload.
4561 * Added Cipher field to the Private Message Key payload to set
4562 the cipher to be used. If ignored, the default cipher defined
4563 in the SILC protocol (aes-256-cbc) is used.
4565 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Removed lib/silcclient/ops.h file.
4569 Redefined parts of the SILC Client Library API. Created new
4570 file silcapi.h that deprecates the ops.h file and defines the
4571 published Client Library API. Defined also private message key
4572 API and channel private key API into the file.
4574 This is the file that the application must include from the
4575 SILC Client Library. Other files need not be included by
4576 the application anymore.
4578 * Added new key_agreement client operation callback and also
4579 defined the Key Agreement library API for the application.
4581 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4584 is used by clients to request key negotiation between another
4585 client in the SILC network. If the negotiation is started it
4586 is performed using the SKE protocol. The result of the
4587 negotiation, the secret key material, can be used for example
4588 as private message key.
4590 Implemented the Key Agreement payload into the files
4591 lib/silccore/silauth.[ch].
4593 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Redefined ciphers for the SILC protocol. Added some new ciphers
4596 and defined the key lengths for the algorithms. Changed the
4597 code accordingly. The default key length is now 256 bits.
4599 * Fixed SKE key distribution function silc_ske_process_key_material
4600 when the key length is more than 128 bits. The default key
4601 length in SILC is now 256 bits.
4603 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4604 to indicate unsupported algorithm.
4606 * Renamed rijndael.c to aes.c and all functions as well.
4608 * Fixed a long standing channel key setting bug in client library.
4609 Weird that it has never surfaced before.
4611 * Fixed bug in channel deletion. If the entire channel is removed
4612 then it must also delete the references of the channel entry
4613 from the client's channel list as the client's channel entry and
4614 the channel's client entry share same memory.
4616 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Implemented CONNECT and SHUTDOWN commands in the client.
4620 * Implemented CLOSE command to the client.
4622 * Added the function silc_idlist_find_server_by_name into the
4623 files silcd/idlist.[ch].
4625 Added the function silc_idlist_find_server_by_conn into the
4626 files silcd/idlist.[ch].
4628 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4630 * DIE command was renamed to SHUTDOWN. Updated the both code
4633 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4634 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4636 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4639 * Added function silc_server_create_connection function to create
4640 connection to remote router. My server implementation actually
4641 does not allow router to connect to normal server (it expects
4642 that normal server always initiates the connection to the router)
4643 so the CONNECT command is only good for connecting to another
4646 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4649 or some other client was kicked from the channel.
4651 Implemented the handling of the notify type to both client
4654 Implemented silc_server_send_notify_kicked to send the KICKED
4655 notify. It is used to send it to the server's primary router.
4657 * Implemented the KICK command into server and client.
4659 * Added `query' argument to the silc_idlist_get_client function
4660 to indicate whether to query the client from server or not if
4663 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4664 to indicate that the client is not channel founder.
4668 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Removed the rng context from SilcPacketContext structure and
4671 changed that the packet routine uses the Global RNG API.
4673 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Added support for quit message that client can "leave" on the
4676 channel when it quits the SILC. It is ditributed inside the
4677 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4679 Added silc_server_free_client_data that will take the
4680 signoff message as argument.
4682 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4684 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Updated parts of the protocol specification to keep it up
4689 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4692 payloads in one packet.
4694 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4695 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4696 use now the new List flag.
4698 * Also deprecated the following packet types: REPLACE_ID,
4699 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4701 * Added list support for Notify packet in server.
4703 * Added silc_server_send_notify_channel_change to send the
4704 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4705 the silc_server_send_replace_id.
4707 * Added silc_server_send_notify_nick_change to send the
4708 NICK_CHANGE notify type. Deprecates the function
4709 silc_server_send_replace_id.
4711 * Added silc_server_send_notify_join to send the JOIN notify type.
4712 Deprecates the function silc_server_send_new_channel_user.
4714 * Added silc_server_send_notify_leave to send LEAVE notify type.
4715 Deprecates the function silc_server_send_remove_channel_user.
4717 * Added silc_server_send_notify_cmode and
4718 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4719 types. Deprecates the silc_server_send_set_mode function.
4721 * Added SERVER_SIGNOFF notify type to indicate that server has
4722 quit. This means that all clients on the channel from that
4723 server will drop. This can be also used when netsplit happens.
4725 Deprecated REMOVE_ID packet type since it is not needed anymore
4728 Added silc_server_send_notify_server_signoff to send the
4729 SERVER_SIGNOFF notify type. Deprecates the function
4730 silc_server_send_remove_id.
4732 Added also silc_server_send_notify_signoff to send the
4733 SIGNOFF notify type.
4735 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4736 SILC protocol from this day on. Changed the protocol
4737 specification as well.
4739 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4740 notify type. It is used between routers to notify about
4741 topic changes on a channel.
4743 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4746 * Partly updated the protocol specification to comply with the
4747 changes now made. It is still though a bit outdated.
4749 * The JOIN notify type now takes one extra argument <Channel ID>.
4750 The packet used to be destined to the channel but now the
4751 JOIN type may be sent as list thus it is impossible to
4752 destine it to any specific channel. By adding this argument
4753 it is again possible.
4755 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Added CREDITS file. The CHANGES and CREDITS file will appear
4758 in the distribution as well.
4760 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4762 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4763 types in the server's silcd/packet_receive.c.
4765 * Implemented CMODE and CUMODE to work in router environment.
4767 * Fixed minor encoding and decoding buglet from the
4768 lib/silccore/silcmode.c.
4770 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4773 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4775 * Changed all SilcConfigServer* and silc_config_server* to
4776 SilcServerConfig* and silc_server_config*, respectively.
4779 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Associated the ID (client or server ID) to the Authentication
4782 Payload to avoid any possibility of forging. Updated the
4783 protocol specification and the code accordingly.
4785 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * The RSA key length is now save to the RsaKey context in the
4788 key generation process in lib/silccrypt/rsa.c. The key length
4789 is now used to figure out the maximum size of the block allowed
4790 to be encrypted/signed.
4792 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4793 is equivalent to the silc_mp_mp2bin but does not allocate any
4796 * Changed silc_mp_mp2bin API to take length argument. If it is
4797 non-zero then the buffer is allocated that large. If zero, then
4798 the size is approximated using silc_mp_sizeinbase, which however
4801 * Created Global RNG API which is global RNG that application can
4802 initialize. After initializing, any routine anywhere in the
4803 code (including library) can use RNG without allocating a new
4804 RNG object. This was done to allow this sort of use of the
4805 RNG in code that has no chance to allocate RNG object. All
4806 applications currently allocate this and many routines in the
4807 library use this. Affected file lib/silccrypt/silcrng.[ch].
4809 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4810 it to use the Global RNG API.
4812 * Defined Authentication Payload into protocol specification that
4813 is used during SILC session to authenticate entities. It is
4814 used for example by client to authenticate itself to the server
4815 to obtain server operator privileges.
4817 Implemented this payload into the lib/silccore/silcauth.[ch].
4818 Implemented also routines for public key based authentication
4819 as the new protocol specification dictates.
4821 Moved definitions of different authentication methods from
4822 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4824 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4825 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4826 silc_pkcs_verify_with_hash functions into the file
4827 lib/silccrypt/silcpkcs.[ch].
4829 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * The client entry's userinfo pointer must be always valid.
4832 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4833 will fail since it requires the userinfo. Now, the userinfo
4834 is allocated as "" if actual userinfo does not exist. Actually,
4835 it must exist and it is totally Ok to drop client connections
4836 that does not announce the userinfo. However, we will make
4837 this workaround for now.
4839 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4840 to return the remote port by socket.
4842 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4845 SILC_SERVER_PENDING_EXEC and added an new macro
4846 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4847 data or when error occurs while processing the pending command.
4849 Added new argument `destructor' into silc_server_command_pending
4850 and to the SilcServerCommandPending object. This destructor is
4851 now called after calling the pending callback or if error occurs
4852 immediately. If error occurs the actual pending callback won't
4853 be called at all - only the destructor. The destructor may be
4854 NULL if destructor is not needed.
4856 All this applies for client library code as well. Similar
4857 changes were made there as well for the pending commands.
4859 In the client, the application must now allocate the
4860 SilcClientCommandContext with the silc_client_command_alloc
4863 * Added reference counter to the SilcServerCommandContext. Added
4864 function silc_server_command_alloc and silc_server_command_dup
4867 Same type of functions added to the client library for the same
4870 * Removed the cmd_ident from IDListData away since it is now
4871 global for all connections. It is the command identifier used
4872 in command sending and with pending commands. The affected file
4875 * Added reference counter to the SilcSocketConnection objecet to
4876 indicate the usage count of the object. The object won't be
4877 freed untill the reference counter hits zero. Currently only
4878 server uses this, and client ignores it. The client must be
4879 set to use this too later. The affected files are
4880 lib/silccore/silcsockconn.[ch]. Added also the function
4881 silc_socket_dup to increase the reference counter.
4883 This was mainly added because it is possible that the socket
4884 is removed underneath of pending command or other async
4885 operation. Now it won't be free'd and proper DISCONNECTING
4886 flags, etc. can be set to avoid sending data to connection that
4887 is not valid anymore.
4889 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4890 the connection. After that it sets SILC_SET_DISCONNECTED.
4891 It is, however, possible that the socket data is not still freed.
4892 The silc_server_packet_process now checks that data is not
4893 read or written to connection that is DISCONNECTED. The socket
4894 get's freed when the reference counter hits zero.
4896 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * Changed the client operation API: channel_message operation's
4899 `sender' is now the client entry of the sender, not the nickname
4900 and the `channel' is the channel entry, not the channel name.
4902 In the private_message operation the `sender' is now also the
4903 client entry of the sender not the nickname.
4905 Affected file is lib/silcclient/ops.h and all applications
4906 using the client operations.
4908 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Moved the calling of ops->connect() from connect_to_server_final
4911 into receive_new_id functin since that is the point when the
4912 client is actually allowed to send traffic to network. The
4913 affected file is lib/silcclient/client.c.
4915 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4918 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4919 (if needs broadcasting) instead of broadcasting the packets one
4920 by one which would make a burst in the network traffic.
4922 * Added `broadcast' argument to the functions in silcd/server.[ch]
4923 silc_server_create_new_channel[_with_id] to indicate whether
4924 to send New Channel packet to primary router.
4926 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Added new function into the silcd/server.[ch] files:
4929 silc_server_create_new_channel_with_id to create new channel with
4930 already existing Channel ID.
4932 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4933 lib/silccore/silcpacket.h. This packet is used t send list of
4934 Set Mode payloads inside one packet. Server uses this to set
4935 the modes for the channels and clients on those channels, that it
4936 announced to the router when it connected to it. The protocol
4937 specification has been updated accordingly.
4939 * The silc_server_new_channel did not handle the packet coming
4940 from normal server as it normally does not send that. However,
4941 when it announces its channels it does send it. Implemented
4942 the support for that.
4944 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4945 into the file lib/silccore/id.h.
4947 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Fixed memory leaks in the functions silc_idlist_del_client,
4950 silc_idlist_del_channel and silc_idlist_del_server in the file
4951 silcd/idlist.c. All of those leaked like a sieve.
4953 * Fixed some small memory leaks in the client's function
4954 silc_client_notify_by_server.
4956 * Added functions into silcd/server.c: silc_server_announce_clients,
4957 silc_server_announce_channels and silc_server_announce_server.
4958 These functions are used by normal and router server to announce
4959 to its primary router about clients, channels and servers (when
4960 router) that we own. This is done after we've connected to the
4963 These functions effectively implements the following packet types:
4964 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4965 and SILC_PACKET_NEW_ID_LIST.
4967 * Added new functions into the silcd/packet_receive.[ch]:
4968 silc_server_new_id_list, silc_server_new_channel_list and
4969 silc_server_new_channel_user_list to handle the incoming
4970 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4972 * Added support of changing Channel ID in the function
4973 silc_server_replace_id. If the server that announces a channel
4974 to the router already exists in the router (with same name but
4975 with different Channel ID), router is responsible to send
4976 Replace ID packet to the server and force the server to change
4977 the Channel ID to the one router has.
4979 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4980 client that the Channel ID has been changed by the router. The
4981 normal server sends this to the client. Client must start using
4982 the new Channel ID as the channel's ID.
4984 Implemented handling of this new type into lib/silcclient/client.c
4985 into the function silc_client_notify_by_server.
4987 * Added new function silc_idlist_replace_channel_id into the files
4988 silcd/idlist.[ch] to replace the Channel ID.
4990 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Call silc_server_command_identify_check always when processing
4993 the IDENTIFY command in silcd/command.c
4995 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4998 send keepalive packets. The packet can be sent by clients,
4999 servers and routers.
5001 Added function silc_socket_set_heartbeat into the file
5002 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5003 If not set, the heartbeat is not performed. The actual
5004 heartbeat is implemented in the low level socket connection
5005 library. However, application is responsible of actually
5008 Added silc_server_send_heartbeat to send the actual heartbeat
5009 packet into silcd/packet_send.[ch]. Server now performs
5010 keepalive with all connections.
5012 * Added silc_task_get_first function into lib/silcutil/silctask.c
5013 to return the timeout task with shortest timeout. There was a bug
5014 in task unregistration that caused problems. TODO has been
5015 updated to include that task system must be rewritten.
5017 * The client library will now resolve the client information when
5018 receiving JOIN notify from server for client that we know but
5019 have incomplete information.
5021 * Rewrote parts of silc_server_remove_from_channels and
5022 silc_server_remove_from_one_channel as they did not remove the
5023 channel in some circumstances even though they should've.
5025 * Encryption problem encountered in server:
5027 The LEAVE command used to send the Channel Key packet to the
5028 router immediately after generating it. However, the code
5029 had earlier sent Remove Channel user packet but not immediately,
5030 ie. it was put to queue. The order of packets in the router
5031 was that Channel Key packet was first and Remove Channel User
5032 packet was second, even though they were encrypted in the
5033 reverse order. For this reason, MAC check failed. Now, this
5034 is fixed by not sending the Channel Key packet immediately but
5035 putting it to queue. However, this is more fundamental problem:
5036 packets that are in queue should actually not be encrypted
5037 because packets that are sent immediately gets encrypted
5038 actually with wrong IV (and thus MAC check fails). So, packets
5039 that are in queue should be encrypted when they are sent to
5040 the wire and not when they put to the queue.
5042 However, the problem is that the current system has not been
5043 designed to work that way. Instead, the packet is encrypted
5044 as soon as possible and left to the queue. The queue is then
5045 just purged into wire. There won't be any fixes for this
5046 any time soon. So, the current semantic for packet sending
5049 o If you send packet to remote host and do not force the send
5050 (the packet will be in queue) then all subsequent packets to the
5051 same remote host must also be put to the queue. Only after the
5052 queue has been purged is it safe again to force the packet
5055 o If you send all packets immediately then it safe to send
5056 any of subsequent packets through the queue, however, after
5057 the first packet is put to queue then any subsequent packets
5058 must also be put to the queue.
5060 Follow these rules and everything works fine.
5062 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Added new function silc_server_remove_clients_by_server to
5065 remove all client entries from ID list when the server connection
5066 is lost. In this case it is also important to invalidate all
5067 client entires as they hold the invalid server entry. This
5068 fixes fatal bug when server has lost connection and will reconnect
5071 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Made some sanity checks to silc_server_daemonise like to check
5074 whether the requested user and group actually exists.
5076 * Added sanity check to SKE's silc_ske_responder_finish to check
5077 that the public and private key actually is valid.
5079 * Invalidate the client's nickname when receiving Replace ID
5080 packet and the Client ID is being replaced. This means that the
5081 server will query the nickname if someone needs it (client)
5084 * Sort the ID Cache in client library when the ID Cache data
5085 has changed (needs sorting).
5087 * Do not allow for SILC client to create several connections to
5088 several servers. The client does not support windows right now
5089 and generating multiple connections causes weird behaviour.
5091 Irssi-silc client does support windows and can handle several
5092 connections without problems, see: www.irssi.org and SILC plugin.
5094 * Fixed some places where client was added to the IDList. The
5095 rule of thumb is following (in order to get everything right):
5096 If the client is directly connected local client then the
5097 `connection' argument must be set and `router' argument must be
5098 NULL to silc_idlist_add_client function. If the client is not
5099 directly connected client then the `router' argument must
5100 bet set and the `connection' argument must be NULL to the
5101 silc_idlist_add_client function.
5103 * The funtion silc_server_packet_send_local_channel actually did
5104 not check whether the client was locally connected or not. It
5105 does that now. Fixed a bug related to LEAVE command.
5107 * Fixed Remove Channel User payload parsing bug in server's
5108 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5110 * The server's silc_server_save_channel_key now checks also the
5111 global ID list for the channel as it might not be in the local
5112 list. Fixed a bug related to LEAVE command.
5114 * Is this the end of the [<unknown>] buglet that has been lurking
5115 around for a long time? A little for loop fix in server's
5116 silc_server_command_whois_parse that is used by both IDENTIFY
5117 and WHOIS command. At least, this was a clear bug and a cause
5118 of one type of [<unknown>] buglet.
5120 * WHOIS and IDENTIFY commands call the function
5121 silc_server_command_[whois/identify]_check function even if
5122 we are not router server.
5124 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Added --with-gmp configuration option. If set the GMP
5127 is always compiled in the SILC source tree. If not set then
5128 it is checked whether the system has the GMP3 installed. If
5129 it has then the GMP won't be compiled (the system's headers
5130 and library is used), if it doesn't have it then the GMP is
5131 compiled in the SILC source tree.
5133 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Changed RSA private exponent generation to what PKCS #1
5136 suggests. We try to find the smallest possible d by doing
5137 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5138 not security fix but optimization.
5140 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Added new config entry [Identity] to fork the server and run
5143 it as specific user and group. A patch from Bostik.
5145 * Imported Dotconf configuration library into lib/dotconf.
5146 This will be used to create the SILC configuration files later.
5147 It will appear in the distsribution after this commit.
5149 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * A big code auditing weekend happening. Auditing code for
5152 obvious mistakes, bugs and errors. Also, removing any code
5155 Removed files for being obsolete:
5157 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5158 inline in the file lib/silcutil/silcbuffer.h)
5160 o lib/silcutil/silcbufutil.c (the header has inline versions)
5162 Changed code to fix possible error conditions:
5164 o The buffer formatting routines now check that the destination
5165 buffer really has enough space to add the data. This applies for
5166 both buffer formatting and unformatting
5167 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5168 unformatting was changed to accomodate following rules:
5169 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5170 sent to the function while XXX_*STRING will not allocate or copy
5171 the data into the buffer. Instead it sets the pointer from the
5172 buffer into the pointer sent as argument (XXX_*STRING used to
5173 require that the pointer must be allocated already). This change
5174 makes this whole thing a bit more consistent and more optimized
5175 (note that the data returned in the unformatting with XXX_*STRING
5176 must not be freed now). The routines return now -1 on error.
5178 o Tried to find all code that use buffer_format and buffer_unformat
5179 and added return value checking to prevent formatting and
5180 especially unformatting errors and possible subsequent fatal
5183 o Changed ske->x and ske->KEY to mallocated pointers in
5184 lib/silcske/silcske.h. Fixed possible data and memory leak.
5186 o Added return value checking to all *_parse* functions. Fixed
5187 many memory leaks as well.
5189 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5190 so that buffer overflows would not happen. All code now also
5191 checks the return value as it can fail.
5193 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Added reconnection support to server if the normal server looses
5196 its connection to the router (for example if router is rebooted).
5197 The server performs normal reconnection strategy implemented
5198 to the server. Affected file silcd/server.c.
5200 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Added new packet type SILC_PACKET_SET_MODE that is used to
5203 distribute the information about changed modes (for clients,
5204 channels and clients channel modes) to all routers in the
5205 network. Updated the protocol specification accordingly.
5207 Added functions into silcd/packet_send.c and
5208 silcd/packet_receive.c: silc_server_send_set_mode,
5209 silc_server_set_mode.
5211 Added new files silcmode.[ch] into lib/silccore that implements
5212 the encoding and decoding of Set Mode Payload. Added new type
5213 SilcSetModePayload. Moved the definitions of different modes
5214 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5216 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5218 * Oops, a little mistake in server's connection authentication
5219 protocol. The protocol is not ended with FAILURE but with
5220 SUCCESS if the authentication is Ok. :) Affected file is
5223 * Implemented NICK_CHANGE notify handling in server in the file
5224 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5225 the local clients on the channel. After the changing nickname
5226 in router environment snhould work and the [<unknown>] nickname
5227 should appear no more.
5229 The silc_server_replace_id function that receives the Replace ID
5230 payload now sends the NICK_CHANGE notify type also in the file
5231 silcd/packet_receive.c
5233 * Changed WHOIS and IDENTIFY command to support the maximum amount
5234 of arguments defined in protocol specs (3328 arguments). This
5235 fixed a bug that caused problems when there were more than three
5238 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * Added extra parameter, command identifier, to the
5241 silc_client_send_command so that explicit command identifier
5244 Changed that ID list routines uses specific command identifier
5245 when sending WHOIS/IDENTIFY requests to the server so that they
5246 can be identified when the reply comes back.
5248 Affected files lib/silcclient/command.[ch],
5249 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5251 * Added `sender' argument to silc_server_packet_send_to_channel
5252 to indicaet the sender who originally sent the packet to us
5253 that we are now re-sending. Ignored if NULL. Affected file
5254 silcd/packet_send.[ch].
5256 * Added some server statistics support in silcd/server_internal.h
5257 SilcServerStatistics structure and around the server code. Also
5258 send some nice statistics information when client is connecting
5261 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5263 * Fixed channel ID decoding in server's JOIN command reply in
5264 silcd/command_reply.c
5266 * Fixed braodcasting of replace ID payload to not to send it if
5267 we are standalone server in silcd/packet_receive.c.
5269 * Fixed all channel message sending routines to not to send
5270 packets to clients that has router set, since they are routed
5271 separately in the same function earlier. Affects file
5272 silcd/packet_send.c and all channel packet sending functions.
5274 * In USERS reply, res_argv[i] are not allocated, the table
5275 is allocated. Thus changed that free the table, not its
5278 * In server's whois_check and identify_check if the client is
5279 locally connected do not send any WHOIS commands - they are not
5282 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Fixed some minor bugs in client when sending WHOIS command. The
5285 arguments was in wrong order.
5287 * Removed statis function add_to_channel from server in
5288 silcd/command.c that was previously used with the joining but
5291 * Tested USERS command in router environment successfully with two
5292 routers, two servers and two clients.
5294 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Reorganized the USERS command and command reply in client library
5297 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5298 When the command is given by user we register a pending command
5299 callback that will reprocess the command after the reply has been
5300 received from the server. When reprocessing the packet we then
5301 display the information. Thus, the USERS information is displayed
5302 now in the command callback instead of in the command reply
5303 callback. The processing of the command is same as previously
5304 when server has sent the command reply in the JOINing process.
5306 * Added to USERS command in silcd/command_reply.c to join the client,
5307 we didn't use to know about, to the channel after we've created
5308 a client entry for it. Also, for clienet we did know already still
5309 check whether it is on the channel or not and add it if not.
5311 * Removed silc_server_command_join_notify as the function and its
5314 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Changed the client's pending command handling to the same as the
5317 server's pending command handling. It is also now possible to
5318 execute command reply functions from other command reply
5319 function as the function callbacks for commands and command
5320 replies are one and same. The pending commands are not static
5321 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5322 in client connection context. Thus, pending commands are server
5323 connection specific as it is convenient.
5325 Changed the function silc_client_command_pending and
5326 silc_client_command_pending_del and added new function
5327 silc_client_command_pending_check. Removed the
5328 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5331 * Added cmd_ident, current command identifier, to the client
5332 connection context in lib/silcclient/client.h to keep track on
5333 command identifiers used in command sending. Client's command reply
5334 function handling now supports the mandatory command identifiers.
5336 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5337 funtions in client to fully support pending command callbacks.
5339 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5340 as one of the arguments to the application in the command reply
5343 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5344 before first releasing SILC but came back. Now it is removed again
5345 and should come back nomore. The FORWARDED flag was used only
5346 by the JOINing procedure by forwarding the command packet to router.
5347 Now, the JOINing procedure has been changed to more generic (due
5348 to various router environment issues) and FORWARDED is not needed
5349 anymore for anything. The protocol specification is yet to be
5352 Now, removed silc_server_packet_forward from server and the flag
5353 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5355 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5357 * Renamed NAMES command to USERS command. The NAMES was named that
5358 due to historical reasons. Now it is renamed. Also, rewrote
5359 parts of the USERS command. The nickname list is not sent anymore
5360 by the server. Only Client ID and mode lists are sent in the USERS
5361 command. Changed this also to the protocol specification.
5363 The client now resolves the names and stuff after it receives
5364 the USERS list from the server when joining to the channel.
5366 * WHOIS and IDENTIFY commands has been changed to support multiple
5367 Client ID's per command. One can now search for multiple users
5368 in the network by sending only one WHOIS or IDENTIFY command.
5369 Changed the code and the protocol specifications.
5371 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5372 uses silc_server_command_whois_parse to parse the request. */
5374 * If normal server, do not parse the WHOIS and IDENTIFY requests
5375 before sending it to the router. Saves some time.
5377 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * Fixed JOIN command on client library. Wrong number of arguments
5380 used to crash the client.
5382 * Added silc_server_channel_has_global function to check whether
5383 channel has global users or not.
5385 * Added silc_server_channel_has_local function to check whether channel
5386 has locally connected clients on the channel.
5388 * The silc_server_remove_from_one_channel now checks whether the
5389 channel has global users or not after given client was removed from
5390 the channel. It also checks whether the channel has local clients
5391 on the channel anymore. If it does not have then the channel entry
5392 is removed as it is not needed anymore.
5394 * The silc_server_notify now checks on JOIN notify whether the joining
5395 client is one of locally connected or global. If it is global then
5396 the channel has now global users on the channel and that is marked
5397 to the channel entry. Also, it now saves the global client to
5398 global list who is joining and JOINs it to the channel. This is
5399 for normal server, that is.
5401 Changed silc_server_send_notify_on_channel,
5402 silc_server_packet_relay_to_channel and
5403 silc_server_packet_send_to_channel check if we are normal server
5404 and client has router set (ie. global client) do not send the
5405 message to that client, as it is already routed to our router.
5407 * Implemented LEAVE notify type handling in silc_server_notify
5410 * Tested LEAVE command in router environment successfully. Tested
5411 with two routers, two servers and two clients.
5415 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5417 * Implemented SIGNOFF notify type handling in silc_server_notify
5420 * silc_server_remove_id now removes the client entry from all channels
5421 it has joined and thusly sends SIGNOFF notify type.
5423 * Rewrote the NAMES list generation in server by removing two excess
5424 loops. The lists are created now inside one loop.
5426 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * silc_server_remove_channel_user checks now also global list
5429 for channel and client.
5431 * silc_server_new_channel_user checks now both local and global
5432 list for channel and client. Fixed a bug in client id decoding.
5433 Used to decode wrong buffer.
5435 * silc_server_channel_message checks now both local and global
5436 list for channel entry.
5438 * Tested channel joining (hence JOIN) in router environment
5439 successfully. Tested with two routers, two servers and two
5442 * Tested channel message sending in router environment successfully.
5444 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Added silc_server_save_channel_key into server.[ch] to save the
5447 received channel key in Channel Key payload processing. It is
5448 also used in JOIN command reply handling.
5450 Equivalent function silc_client_save_channel_key added into
5451 client.[ch] into client library.
5453 * Changed JOIN command reply to send information whether the channel
5454 was created or not (is existing already) and the channel key
5455 payload. Changed protocol specs accordingly.
5457 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5458 the request was sent by ID and not by nickname. Crashed on
5461 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5463 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5464 now correctly save the received data.
5466 * silc_server_free_sock_user_data now notifies routers in the
5467 network about entities leaving the network.
5469 At the same time implemented functions silc_server_remove_id
5470 and silc_server_send_remove_id to receive and send REMOVE_ID
5471 packets. The packet is used to notify routers in the network
5472 about leaving entities. The ID removed will become invalid in
5475 * Added function silc_idlist_del_server into server. Removes and
5476 free's server entry from ID list.
5478 * silc_server_private_message function now checks, if we are router,
5479 that the destination ID really is valid ID, naturally.
5481 * In router when NEW_ID packet is received (for new client) the
5482 hash of the Client ID is saved in the ID Cache but the
5483 client->nickname is set to NULL, instead of putting the hash
5486 IDENTIFY command now also checks that client->nickname must be
5487 valid. If it is not if will request the data from the server who
5488 owns the client. Added new function
5489 silc_server_command_identify_check.
5491 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5492 to set the command to already allocated Command Payload.
5494 * Tested private message sending in router environment with two
5495 routers, two servers and two clients. Fixed minor bugs and now
5498 * Fixed segfault from client's NAMES command. Used to crash if
5501 * Forwarded packets must not be routed even if it is not destined
5502 to the receiver. Changed server code comply with this.
5504 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Added `require_reverse_mapping' boolean value to ServerParams
5507 structure. If TRUE (not default) the server will require that
5508 the connecting host has fully qualified domain name.
5510 If the reverse mapping is not required and hostname could not be
5511 found the IP address is used as hostname.
5513 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Implemented version string checking to both client and server.
5516 The check is incomplete currently due to the abnormal version
5517 strings used in development version of SILC.
5519 * Changed all command functions in server to use the new
5522 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Changed char *data to unsigned char *data in ID Cache system to
5525 support binary data as ID Cache data. Changed code to support
5526 binary data in lib/silccore/idcache.c.
5528 * Renamed silc_server_packet_relay_command_reply to
5529 silc_server_command_reply as it is normal packet receiving
5530 function. Rewrote the function to accept command replys for
5531 servers and not only for clients.
5533 * Mark remote router always as registered server if we are connecting
5534 to it. Otherwise, commands sent by the router to us are ignored.
5536 * All ID List find routines now returns the ID Cache Entry pointer
5537 as well if requested.
5539 * WHOIS command works now in router environment, tested with two
5540 routers, two servers and two clients.
5542 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5543 in router environment (as it is almost equivalent to WHOIS) but
5544 hasn't been tested thoroughly. Added new functions:
5546 silc_server_command_identify_parse
5547 silc_server_command_identify_send_reply
5548 silc_server_command_identify_from_client
5549 silc_server_command_identify_from_server
5551 * Disabled route cache adding because adding two different ID's with
5552 same IP replaces the old cache entry thus giving wrong route.
5553 The entry->router->connection is always the fastest route anyway
5554 so route cache may not be needed. Of course, new routes maybe
5555 established after receiving the ID when the entry->router->connection
5556 might not be anymore the most optimal.
5558 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Add route cache for received ID for fast routing.
5562 * Added silc_server_packet_route to route received packet on router
5563 that is not destined to us.
5565 * Renamed silc_server_get_route to silc_server_route_get.
5567 * Added id_string and id_string_len fields into SilcServer to
5568 include encoded ServerID for fast comparing without excess
5569 encoding of the ID's.
5571 * Cleaned up WHOIS command on server side. Added following static
5574 silc_server_command_whois_parse
5575 silc_server_command_whois_check
5576 silc_server_command_whois_send_reply
5577 silc_server_command_whois_from_client
5578 silc_server_command_whois_from_server
5580 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5581 arguments in command replies. All command functions should be
5582 updated to use this macro.
5584 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5586 * Minor typo fixes on command reply handling on server.
5588 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Added silc_server_command_add_to_channel internal routine to add
5591 the client to the channel after router has created the channel and
5592 sent command reply to the server.
5594 * Added generic silc_server_send_command to send any command from
5597 * Use static buffer with ID rendering instead of duplicating data.
5599 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * Fixed a channel user mode bug when joining to a channel server gave
5602 everybody channel founder rights, oops.
5604 * We mark ourselves as the router of the incoming server connection
5605 if we are router ourselves. This way we can check in some packet
5606 sending functions whether it is locally connected server. For
5607 incoming router connections we put NULL.
5609 * For router sending packets locally means now always sending the
5610 packet cell wide; to local clients and local servers. For normal
5611 server sending packet locally means sending it to only local
5614 * Fixed the JOIN command to really work in router environment. If the
5615 channel is created it is always created by the router. Router is
5616 also responsible of making the initial joining to the channel,
5617 sending JOIN notify to the sending server and distributing
5618 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5619 does not exist server doesn't do anything else but forward the
5620 command to the router which performs everything.
5622 * Added silc_server_send_channel_key function to send the Channel Key
5625 * Added silc_server_create_channel_key to create new channel key. The
5626 channel key is now re-generated everytime someone joins or leaves
5627 a channel, as protocol dictates. Note: channel->key_len is the
5630 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5633 packet_receive.[ch] to separate packet sending and receiving
5634 routines. The server.[ch] now includes everything else including
5635 actual packet processing (writing and reading data) and other
5638 Renamed silc_server_private_message_send_internal to
5639 silc_server_send_private_message. The routine is still though
5640 used only to relay private messages as server does not send
5641 private messages itself.
5643 Renamed silc_server_new_channel to silc_server_create_new_channel
5644 and added new function sicl_server_new_channel that handles the
5645 incoming New Channel packet. Added also new sending function
5646 silc_server_send_new_channel to send New Channel Payload.
5648 * Added new function silc_server_notify to process incoming notify
5649 packet to the server/router. Server may then relay the notify
5650 to clients if needed.
5652 * Added new function silc_server_new_channel_user to process incoming
5653 New Channel User packet. Router will redistribute the packet and
5654 send JOIN notify to its local clients and locally connected servers
5655 if needed. Normal server will send JOIN notify to its local client
5656 on same channel when received this packet. Added also corresponding
5657 sending function silc_server_send_new_channel_user to sent the
5660 * Added boolean route argument to send_notif_to_channel and
5661 packet_send_to_channel functions to attempt to route the packet
5662 if it is TRUE and send only locally if it is FALSE.
5664 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5666 * silc_server_replace_id now broadcasts the received replace ID
5667 packet if it is not broadcast packet already. The router must
5668 broadcast to inform other routers about changed ID.
5670 * Added backpointer to server's router into SilcServer context in
5671 silcd/server_internal.h.
5673 * Fixed silc_server_packet_broadcast to send correct broadcast
5676 * The channel key is now distributed to the local client as soon
5677 as it is received from the router (in router environment) so that
5678 no other packet may be sent for the channel until client has
5681 * silc_server_remove_channel_user now broadcasts the received
5682 Remove Channel User packet if it is not broadcast packet already.
5683 The router must broadcast to inform other routers about removed
5686 * Added users field into SilcPacketContext that is a reference count
5687 of the context. One can increase the reference count by calling
5688 silc_packet_context_dup which is now changed to just increase the
5689 reference count instead of duplicating the data. The reference
5690 count is decresed by calling silc_packet_context_free that will
5691 free the data after the reference count hits zero.
5693 For now on the packet context and everything allocated into it
5694 (including the raw packet from network) must be freed by calling
5695 the new silc_packet_context_free function. Added also new function
5696 silc_packet_context_alloc that must be used now to allocate the
5697 context. This also means that if a routine is asynchronous from
5698 silc_[client/server]_packet_parse_type the packet context must
5699 be duplicated by calling silc_packet_context_dup. Otherwise it
5700 gets free'd after silc_[client/server]_packet_parse_type returns.
5701 Also, one must remember that if packet is duplicated then its
5702 reference count must be decresed by calling the free function as
5703 many times as it was duplicated.
5705 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5706 from both client and server.
5708 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Made joining to a channel working in router environment.
5712 * Cleaned up JOIN command on server side and create function
5713 silc_server_command_join_channel internal routine to make the
5716 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Changed silc_command_pending list to SilcDList. Also, added
5719 `ident' field to SilcServerCommandPending structure to identify
5720 the reply and to call correct callback.
5722 Added silc_server_command_pending_check function to replace the
5723 corresnponding macro. The silc_command_pending list is not
5726 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5727 to set identifier to previously allocated Command Payload. It
5728 is used to set identifier for command when resending Command
5731 * Added silc_command_payload_encode_payload to encode Command
5732 Payload buffer from SilcCommandPayload structure.
5734 * Added silc_argument_payload_encode_payload to encode Argument
5735 payload buffer from SilcArgumentPayload structure.
5737 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Changed WHOIS command to support router connection on server side.
5740 The whois request is always sent to router unless the server is
5741 standalone server. After server has received the reply from the
5742 router will it send the reply to the client.
5744 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5745 broadcast received broadcast packet. The function is used only
5746 by router. The broadcast packet is always sent to the router's
5749 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5750 render given ID to printable string, for log files for example.
5752 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Made basic router to router connections working. At least they
5755 can now connect to each other but nothing really works the way
5756 they are supposed - yet.
5758 * Added new initiator token to RouterConnection configuration
5759 file in silcd/serverconfig.[ch]. It is used to tell whether we
5760 are the initiator to the remote router or whether we'll expect
5761 the other end to connect.
5763 * Moved registering of listener task to silc_server_init, hence
5764 the server starts listenning as soon as it is run, even if it
5765 does not have connections to other routers. Let's see how well
5768 * Changed default connection retry timeouts for more suitable in
5771 * Removed cipher and such arguments from silc_idlist_add_client
5772 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5773 Added new function silc_idlist_add_data to add the keys and stuff
5776 * Added SilcIDListData structure and added it to SilcClientEntry
5777 and SilcServerEntry as their first field in the structure. This
5778 way we can explicitly cast the ID entries to the SilcIDListData
5779 structure and get common data for the entries. In past, we had
5780 to first check what type of connection it is and then cast it to
5781 correct ID entry type. Now, we can directly cast the opaque
5782 pointer to the SilcIDListData (no matter what ID entry it actually
5783 is) and get the data needed.
5785 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5787 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5788 in some circumstances even if threre were timeout tasks, though not
5789 IO tasks, but tasks anyway. Now fixed.
5791 * Defined SilcServerConnection structure to hold connection specific
5792 stuff about directly connected servers and routers. The definition
5793 is currently in silcd/server_internal.h. I thought about having
5794 a bit more important role fro this struct but for now it is used
5795 only when connecting to other server (or router actually).
5797 * Added connecting retry support in server when connecting to
5798 router(s). The retry feature implement exponential backoff
5799 algorithm. Also, added SilcServerParams structure to hold default
5800 parameters for server. For now, it include these retry settings
5801 and are hard coded. After server is moded to be as Silc Server
5802 Library this structure will be more important.
5804 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Changed client librarys channel->clients table to SilcList and
5807 changed code accordingly.
5809 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Changed client's channel table to SilcList and changed code
5812 accordingly. Also changed SilcChannelClientEntry to include back-
5813 pointer to the channel so that client entry can use that structure
5814 as list as well and we have fast cross-reference to the channel.
5815 This change dramatically decreased the complexity of channel
5816 handling with client entry and vice versa (removed one extra
5817 loop when searching for channel entry from many functions).
5819 * Changed server->sim from table to SilcDList and changed code
5822 * NAMES command can now be used from user interface. It will show
5823 the user list on the channel, neatly.
5825 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5826 Code now saves realname of the user if it becomes available.
5828 * Renamed configure.in to configure.in.pre and made ./prepare
5829 script to automatically add correct version string to
5830 configure.in which it creates from configure.in.pre.
5832 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * NAMES command reply now shows users mode with the nickname when
5837 * Moved silc_client_ch[u]mode[_char] functions from
5838 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5839 place sucks, they are utility functions and should be in some
5842 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5844 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5847 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Added TRQ (efficient deque and list library) into lib/trq. This is
5852 a very good list library that is currently used in the SILC. Defined
5853 SilcList API over the library because I didn't like the API very
5854 much. See lib/trq/silclist.h for the API and examples of how to
5855 use the API. Fixed various places in the code to use the new
5856 SilcList API. The SilcList is meant for lists that has a structure
5857 already defined as a list. It is not suitable to add just some
5858 context to the list (in TRQ, the context is the list actually).
5860 So, I defined SilcDList that can be used for the purpose where
5861 predefined list structure does not exit. This can be used as
5862 such list. Now some context just can be added to the SilcDList.
5863 Currently this list is not used in the SILC just yet, though there
5864 are a lot places where this can replace dynamically allocated
5865 tables and I will fix these places, later, to use SilcDList.
5866 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5867 and use TRQ internally).
5869 Also fixed some annoying warning messages that the original TRQ
5870 code generated. Also minor changes to TRQ's Makefile.in.
5872 * Added support for querying by Client ID to both WHOIS and
5873 IDENTIFY commands into server, as required by the protocol.
5875 * Removed method function pointers from SilcBuffer structure. They
5876 weren't used to anything and just increased the context size for
5877 no good reason. This change also made silc_buffer_alloc and
5878 silc_buffer_free functions inline functions.
5880 * Disabled command flooding detection support until it's fixed so
5881 that it accepts commands in but does not execute them more than once
5884 * Added silc_net_localhost(), to return local hostname, into
5885 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5886 that must be initialized before calling silc_client_init.
5888 * Added new function: silc_server_send_notify_on_channels to send
5889 notify messages to all channels client has joined. It is assured
5890 that the message is sent only once per client.
5892 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5893 lib/silcutil/silcutil.[ch] as silc_format function. The new
5894 function is generic and is used by server as well, not only by
5895 the logging routines.
5897 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5898 the provided version string was not acceptable. Added new function:
5899 silc_ske_check_version into lib/silcske/silcske.h. The function
5900 must be implemented by the application (client or server) and it
5901 does not reside in the SKE library. The function checks the version
5902 string remote end sent.
5904 * Added back pointers (to opaque context and to SilcSocketConnection)
5905 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5907 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5908 duplicate packet context structure.
5910 * Changed `notify' client operation to send same arguments as client
5911 receives from server except for ID's. ID's are mapped to correct
5912 ID entry and that is returned. Also, if channel entry is not sent
5913 by server but the notify is for channel the channel entry is sent
5914 to application (otherwise application doesn't know that it is for
5915 channel (library gets it from packet's Destination ID)).
5917 * Added silc_client_remove_from_channels into client library to
5918 remove a client from all channels it has joined to. Used when
5919 received SIGNOFF notify from server. Added also new function
5920 silc_client_replace_from_channels to replace old ID entry with
5921 new ID entry on all channels. Used when received NICK_CHANGE
5924 * Fixed ID Cache list handling in silc_idlist_get_client in
5925 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5926 to get (or query) client by ID.
5928 * Updated TODO list.
5930 * Added connection authentication status message defined by the
5931 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5932 support for these into the code in client and server side.
5934 * Added generic function silc_client_send_command to send any command
5935 with variable argument list. Application should use this function
5936 to send commands if the command functions provided by the library
5937 does not suite for the application's user interface needs.
5939 * Added new `failure' client operation. Application is notified about
5940 received failure packet if client is executing a protocol. In this
5941 case the protocol's execution has failed.
5943 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5944 is required by the protocol.
5946 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5947 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5950 * Added status flag to SilcSKE object to indicate realtime status
5951 of the SKE protocol.
5953 * Application receives now exactly same command reply arguments as
5954 the library receives from server. However, if ID is received the
5955 corresponding ID entry is returned to the application (eg. Client
5956 ID is mapped to correct SilcClientEntry entry and that is returned).
5957 Changed command_reply client operation due to this change.
5959 * Changed all ID's in commands and in command replys as ID Payloads.
5960 Change affected both client and server side codes.
5962 All ID's sent in SILC network (with execption of ID's in SILC
5963 Packet header) are sent in ID Payload to support variable length
5966 * Server now notifies nick changes and notifies all clients on
5967 the channels about the new nickname (about the new Client ID,
5970 * Implemented CMODE command to change channel modes. Supports all
5971 channel modes defined by the protocol specs except ban and invite
5972 lists. (Also, private channel key mode is supported but support for
5973 setting private channel key in client is missing, thus, this mode
5974 has no effect on client side (except that server requires that the
5975 client uses private channel key and normal channel traffic does not
5978 Also, invite mode works per se, but INVITE command does not work
5979 yet correctly, so you can set channel as invite only channel but
5980 inviting clients to the channel does not work (it is yet to be
5981 thought what's the best way to do it).
5983 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5984 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5985 Implemented CUMODE command to change user's mode on the channel.
5986 Supports all modes defined by the protocol specs.
5988 * Added NAMES command reply to return users modes on the channel.
5990 * Removed unnecessary and slow ciphers from lib/silccrypt.
5992 * Set SO_KEEPALIVE option to connection sockets by default.
5994 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5996 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5997 redefined the Notify Payload into protocol specs.
5999 * Added silc_id_payload_parse_id to get ID directly from raw
6002 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6005 accept searching by Client ID as well.
6007 * Added support for LEAVE and SIGNOFF notify types in client library.
6009 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6010 to parse ID Payload from raw data.
6012 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Added flags parameter into silc_ske_assemble_security_properties
6015 function in lib/silcske/silcske.[ch].
6017 * Changed notify client operation to fit better for notify messages
6018 sent by server. The notify payload received from server is now
6019 passed to the application (after parsing it to SilcNotifyPayload).
6020 It is application's responsibility to retrieve the arguments
6021 from the payload and show the message the way it wants. The message
6022 sent by server is implementation specific.
6024 * Changed public keys to comply with the protocol specification.
6025 Old public keys are not supported anymore and are not compatible.
6027 * Removed nickname from Channel Payload as the latest draft removed
6028 it. The client must resolve the nickname from the NAMES command
6029 reply received when it joined the channel.
6031 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6033 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Fixed some errors in protocol specification drafts.
6037 * Created lib/silccore/silcnotify.c to implement Notify Payload
6038 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6039 generic payloads described by protocol specifications. The file
6040 includes implementations for ID Payload and Argument Payload.
6042 * Changed Command Payload implementation to use the new Argument
6043 Payload. Changed command_xxxx_payload to command_payload_xxxx
6044 to comply with SILC coding conventions.
6046 * Added suppport for Argument Payload handling in Notify Payload
6047 implementation as protocol requires it. Added the new support
6048 into server and client lib as well.
6050 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Added support for multiple nicknames on same channel. [n] is
6053 added locally to the nickname if there are more than one same
6054 nicknames on the channel.
6056 * Server now sends all nicknames that matched WHOIS request.
6057 Client also shows the list received from server.
6059 * Added TOPIC command to client side. User can now set and show
6060 current topic on channel.
6062 * Added MOTD command to client and server. Also, server sends the
6063 motd when client connects to the server.
6065 * Changed version strings to comply ISO 8601.
6067 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * Fixed protocol error handling in client library. It should now
6070 cope even if the SKE fails for some reason.
6072 * Made new protocol specification drafts for submitting to IETF.
6074 * Implemented TOPIC command to server in silcd/command.c.
6076 * Added two new notify types into lib/silccore/silcnotify.h:
6077 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6078 notify nickname change and topic setting/change on a channel.
6080 * API change of command_reply operation in client library. The
6081 application gets now the status type received from server as well.
6083 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6087 * Cras fixed and optimized the packet handling even further and
6088 it should work now. Minor change to the prototype of function
6089 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6091 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Added new function into lib/silcutil/silcschedule.[ch]:
6094 silc_schedule_with_fd to select() a specified fd. The function
6095 returns after timeout expires or data arrives or goes. The
6096 function is used by packet routines to wait that all data is
6097 received from network.
6099 * Fixed data reading from network in lib/silccore/silcpacket.c.
6100 The code now assures that all data is read from the fd and then
6101 continues packet processing. This was a bug fix since the code
6102 used to drop some data in some circumstances.
6104 * Added new function into lib/silcclient/client.[ch]:
6105 silc_client_start_key_exchange to start key exchange after
6106 connection has been established to server. The code internally
6107 now uses this funtion but its main purpose was to provide it
6108 for applications that perform their own connecting. After
6109 application has created a connection it merely calls this
6110 function to start the key exchange between client and server.
6111 The library takes care of everything else after that.
6113 Updated also lib/silcclient/README to explain the usage of
6116 * Do not send to application information that connection has
6117 been established. Application gets notified it by connect
6120 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6122 * Applied cras's patch to add silc_schedule_one function. The
6123 function runs scheduler once and returns.
6125 * Fixed the scheduler after cras messed it up. The timeout
6126 handling works now as it's supposed to work.
6128 * Added into lib/silccore/ silcnotify.h to include notify
6129 message types support. Changed silc_server_send_notify*
6130 functions, in server.[ch], to support those new notify types.
6131 Added the support for the notify types into client library,
6132 as well. Added new notify client operation into ops.h in
6135 * Changed silc_server_packet_send_to_channel to send normal
6136 packets instead of just channel message packets. The function
6137 is now used to send the notify packets to channels. It is not
6138 used to send channel message packets anymore, as server never
6141 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6142 va_arg()s as it seems to require it nowadays. I guess, if SILC
6143 is compiled with older va_arg() the new code should work anyway.
6145 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Splitted core library. Core library (lib/silccore) includes
6148 now only SILC protocol specific core (and common) components.
6149 Created new utility library (lib/silcutil) that includes more
6150 generic purpose stuff. The stuff for util library was taken
6151 from the old core library. This was minor and easy split.
6153 * Created SILC Client Library (lib/silcclient) that includes
6154 implementation of the SILC client without user interface. This
6155 was major move from silc/ directory. The code has been changed
6156 so that it is transparent towards the user interface. The
6157 silc/ directory includes now the same user interface as before
6158 and it uses the new client library. Read lib/silcclient/README.
6159 Basicly, the client library performs everything else related
6160 to SILC except user interface handling. Also, configuration
6161 files are considered to be part of user interface and library
6162 does not handle them.
6164 This change also changed a lot of structures, function naming etc.
6165 Most important change was that SilcClientWindow object was
6166 renamed to SilcClientConnection in the client library. Created
6167 also new file lib/silcclient/ops.h. Also added new files
6168 silc/local_command.[ch] and silc/client_ops.[ch].
6170 All these changes were made to make it easier for user interface
6171 designers to create what ever user interface for the SILC client
6174 It is also expected that the server will be moved to lib
6175 directory as well and SILC Server Library will be created;
6176 sometimes in the future.
6178 * Removed Local commands from lib/silccore/silccommand.h as
6179 they are application specific and new client library does not
6180 handle any of those anymore.
6182 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6183 old client implementation in silc/.
6185 * Added support for callback functions in SILC_LOG_* macros.
6186 Application can now set its own callbacks that will be called
6187 instead of using the default functions that will always print
6188 the debug messages to stderr (or stdout). Also, debugging can
6189 now be disabled by setting silc_debug to FALSE and re-enabled by
6190 setting it to TRUE. Note, that logging will still work even
6191 if debugging is disabled.
6193 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6194 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6195 silc_log_reset_debug_callbacks.
6197 * To enable debugging in silc client one must give now -d
6198 option on command line.
6200 * Changed silc_schedule_init to automatically allocate task queues
6201 if they are not allocated before calling it.
6203 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6205 * Added GMP 3.1 into math library.
6207 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6209 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6210 a channel in SILC network. The packet is used by servers and
6211 routers to notify other routers that user has left a channel.
6212 This little feature was missing until now. Added the feature
6213 to protocol specification as well.
6215 Added functions: silc_server_send_remove_channel_user and
6216 silc_server_remove_channel_user into server.[ch].
6218 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6219 lib/silccore/silcpacket.h. However, they are not implemented
6222 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6224 * Fixed joining to a channel and sending channel messages
6225 between server and router. The channel message sending should
6226 now work inside a cell.
6228 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6230 * Fixed the private message sending between server and router.
6231 The private message sending should now work inside a cell.
6233 * Added silc_server_replace_id into server.[ch] to replace
6234 existing ID in the SILC network.
6236 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6237 and silc_idlist_replace_server_id into idlist.[ch] in server.
6239 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6241 * Fixed the server to server connections. Server can again now
6242 connect to router. Router to router connections probably does
6245 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6247 * Added dynamic protocol registering support. Now protocols can
6248 registered and unregistered on the fly. Patch by cras.
6250 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * Added lib/contrib directory to hold routines that some platforms
6253 don't have but are needed by SILC.
6255 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6256 into lin/contrib to provide getopt() and getopt_long() for
6257 those who don't have it.
6259 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Added AWAY command to client. When away message is set and
6262 client receives a private message packet the client automatically
6263 replies to the sender with the away message.
6265 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6266 bug seemed to be the cause of recent problems when compiling
6269 * Added version detection support to SKE protocol specification
6270 and added the new changes to the SKE implementation as well.
6271 There were other minor changes in the SKE protocol as well.
6273 Many changes in lib/silcske/silcske.[ch] and in
6274 lib/silcske/payload.[ch].
6276 * Added ^U functionality, clear input line. Patch from cras.
6278 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * Mainly small bugfixes on core library. Fixed some debugging
6281 logging and buffer overflow in silclog.c.
6283 * Updated config.sub and config.guess on the distribution tree.
6285 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6287 * Added command lagging support in server. Client may execute
6288 commands now only once in two seconds.
6290 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6292 * Optimized packet reception. MAC computation and checking is now
6293 also more optimized. A lot previously duplicated code is now
6294 used as generic by both client and server.
6296 * Fixed key pair generation in clientutil.c
6298 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6300 * Added into lib/silccore/silcbufutil.[ch] new function;
6301 silc_buffer_realloc.
6303 * Moved generic packet sending/encryption functions to
6304 lib/silccore/silcpacket.[ch] from client and server. Some
6305 rewriting of the functions.
6307 * Moved all generic packet reception/decryption functions to
6308 lib/silccore/silcpacket.[ch] from client and server. The
6309 packet processing is now much cleaner in both client and server.
6310 These were major changes in both client and server.
6312 * Created many common functions in server to do packet sending.
6313 Previously code were duplicated a lot, this has been removed
6316 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6318 * Rewrote major parts of the ID cache system. Don't know
6319 whether it is better now or not but at least the API is more
6322 * Major rewrite on ID cache stuff on client because of the ID
6323 cache API changes. Added idlist.c to client.
6325 * Also major rewrite on ID cache stuff on server as well.
6326 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6327 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6328 in hand, instead they are all put into the ID cache system now.
6329 All server_idlist_* routines uses ID cache now instead of
6330 traversing its own lists (those lists does not exist anymore).
6331 SilcIDList though still exists. Also, SilcXXXEntry's are
6334 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Finally made the SKE implementation compliant to the protocol
6337 specification. All mp integers are now binary encoded as
6338 opposed being HEX encoded.
6340 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6343 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6344 functions: silc_[encode/decode]_pem. Also added function
6345 silc_encode_pem_file to PEM encode with newlines ('\n') for
6348 * SILC public keys are now encoded either PEM or binary. Same
6349 option is for private keys as well. By default private keys
6350 are binary encoded and public keys PEM encoded. Silly HEX
6351 encoding were removed.
6353 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6354 function to create fingerprints.
6356 * Fixed a bug in SHA1; does not change the original data anymore.
6358 * Partly implemented INFO command on client and server side.
6359 Fixed CLEAR command. Changes to SERVER command; show current
6360 server(s) when giving command without arguments. Added
6361 VERSION command to client.
6363 * Added check to server that unregistered connections cannot
6364 execute commands (unless it is specificly allowed).
6366 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * Fixed screen refresh.
6370 * Fixed channel joining bug from client. On some circumstances
6371 client tried to join to a channel it had already joined.
6373 * Added public key verification process into client's protocol.c.
6374 The client now verifies the public key from user and saves
6375 it into ~./silc/serverkeys/ directory.
6377 Added into: clientutil.[ch]: silc_client_verify_server_key.
6379 * Changed SKE protocol's silc_ske_initiator_finish function
6380 to accept callback function that verifies the received public
6381 key. Removed old silc_ske_verify_public_key function.
6383 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6385 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6386 silc_pkcs_private_key[_data]_set.
6388 * Made the password and public authentication more cleaner in
6389 server's protocol.c.
6391 * Removed historic and obsolete protocol `channel_auth' from
6392 both client and server.
6394 * Removed wrong way of sending command status messages from
6395 server to client in server's command.c. The old way violated
6396 protocol specification.
6398 Changes to silccore/silccommand.[ch]: removed
6399 silc_command_encode_status_payload -> not needed anymore,
6400 changed silc_command_encode_payload_va to accept extra
6401 argument on variable argument list. The argument type must
6402 now be provided to the function. Also, added new function:
6403 silc_command_encode_reply_payload_va which is same as
6404 normal command_encode_payload_va except command status type
6405 is provided as extra argument.
6407 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * Added ~./silc directory handling. The directory includes the
6410 public and private keys for the client.
6412 Added silc_client_check_silc_dir, silc_client_create_identifier
6413 and silc_client_load_keys.
6415 * Implemented SILC protocol compliant public key. Added public
6416 and private key saving to and loading from files.
6418 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6419 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6420 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6421 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6422 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6424 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6425 silc_pkcs_load_[public/private]_key.
6427 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Added silc_server_get_route (route.[ch]) to get connection
6430 data for the fastest route for given ID.
6432 * Implemented INVITE command on client and server. The command
6433 were re-defined in the SILC Protocol Specification and the
6434 implementation now complies with the specification.
6436 * Implemented PING command on client and server.
6438 * Implemented NAMES command on client and server. The server side
6439 supports currently only normal server not router server yet.
6440 Some changes to NAMES definition in SILC protocol specification.
6442 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6444 * Implemented LEAVE command on client and server.
6446 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6447 again. This change was made to the protocol as well. Server
6448 should not violate the protocol specification anymore.
6450 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6453 was tested. SOCKS4 was not but should work anyway.
