1 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed the server's password authentication to use the
4 length of the locally saved password, and not the one
5 sent in the packet. Affected file silcd/protocol.c.
7 * Fixed same password authentication problem in the
8 Authentication Payload handling routines in
9 lib/silccore/silcauth.c.
11 * Yet another password authentication problem fixed with
12 channel password handling in silcd/command.c.
14 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
16 * If first character of string in silc_parse_userfqdn is '@'
17 then do not parse it. Affected file is
18 lib/silcutil/silcutil.c.
20 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
22 * Fixed minor bug in IDENTIFY command reply sending, which
23 caused various weird problems during JOIN when it was
24 resolving names for users. Affected file silcd/command.c.
26 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
28 * Fixed the IDENTIFY command reply sending to chech better valid
29 clients. It was possible to send incomplete list of replies.
30 Affected file silcd/command.c.
32 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
34 * Added silc_client_command[s]_[un]register functions now to
35 dynamically register the commands in client library. Removed
36 the static table of commands. This allows the client library
37 to call commands without causing the application to know about
38 what commands library has called.
40 Removed the INFO command reply kludge to detect when the command
41 was called by library. Now library use its own command reply
42 function for INFO command.
44 Added function silc_client_command_call to call a command.
45 Application can use it to call command, not access the structure
48 Now all commands that are sent by the client library (not
49 explicitly sent by application) use own command reply functions.
51 Affected files around lib/silcclient/ and in
54 * Fixed the WHOIS command reply sending to chech better valid
55 clients. It was possible to send incomplete list of replies.
57 Fixed the WHOIS and IDENTIFY to send the request to router
58 if normal server did not do it and did not find any results.
60 Affected file silcd/command.c.
62 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
64 * Moved the internal data from SilcClient context into its
65 own file, not accesible to application. Affected files
66 lib/silcclient/client.h and lib/silcclient/client_internal.h,
67 and other files in client library.
69 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
71 * Added doc/examples installation target in Makefile.am.pre.
74 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
76 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
77 commands the found client entry will be removed from the
78 cache, after notifying application about the error. Affected
79 file lib/silcclient/command_reply.c.
81 * Changed the /MSG to check for exact nickname user gave, and
82 not let `nick' match `nick@host' if it is only one found. Now,
83 user must type the exact nickname (like nick@host2) even if
84 there are no more than one same nicks found. This is to avoid
85 a possibility of sending nickname to wrong nickname since
86 `nick' could match `nick@host'. Affected file is
87 irssi/src/core/silc-servers.c.
89 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
91 * Do not print "you are now server operator" or similar when
92 giving /away command. Affected files are
93 irssi/src/silc/core/client_ops.c, silc-servers.h.
95 * Made the silc_server_command_pending_error_check to send
96 the same command reply payload it received back to the
97 original sender of the command. This way all arguments
98 that was received by the server will be received by the
99 client too. Affected file silcd/command.c.
101 * Added the silc_idcache_add to return the created cache entry
102 to a pointer. Affected file lib/silccore/silcidcache.[ch].
104 * Add global clients to expire if they are not on any channel.
105 This is because normal server will never know if they signoff
106 if they are not on any channel. The cache expiry will take
107 case of these entries. This is done by normal servers only.
108 The affected files are silcd/command_reply.c,
109 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
111 * If server receives invalid ID notification for WHOIS or
112 IDENTIFY and the ID exists in the lists, it is removed.
113 Affected file silcd/command_reply.c.
115 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
116 in client then client entry that it matches is searched and
117 the nickname is printed on the screen for user. Affected
118 file irssi/src/silc/core/client_ops.c.
120 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
122 * Use cache entry expire time in the LIST command reply to
123 purge old entries from the cache after the LIST command
124 reply has been received. This way we don't have non-existent
125 entries in the cache for too long. Affected file is
126 silcd/command_reply.c.
128 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
130 * If we are normal server, and we've not resolved client info
131 in WHOIS or IDENTIFY from router, and it is global client,
132 we'll check whether it is on some channel. If it is not
133 then we cannot be sure about its validity and will resolve it
134 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
135 file silcd/command.c.
137 * Search channel by name (if possible) rather than by ID
138 in IDENTIFY command's command reply. Affected file is
139 silcd/command_reply.c.
141 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
143 * Distribute to the channel passphrase in CMODE_CHANGE notify.
144 Updated specs and implemented it. Affected file silcd/command.c,
145 silcd/packet_send.c and silcd/packet_receive.c.
147 * Implemented the <founder auth> payload handling in the JOIN
148 command. If provided all conditions for channel joining
149 except requirement to provide correct passphrase can be
150 overrided by the channel founder. Updated the protocol specs.
151 Affected file silcd/command.c.
153 Added support for founder auth in JOIN command in client
154 library. Fixed the parsing of the JOIN command now to support
155 all options as they should be. The affected file is
156 lib/silcclient/command.c.
158 * Optimized the WHOIS and IDENTIFY commands to send the request
159 to router only if it includes nicknames or other names. If
160 they include only IDs then check the local cache first before
161 routing. Affected file is silcd/command.c.
163 * Added channels topic announcements. Affected file is
164 silcd/packet_receive.c and silcd/server.c.
166 * Fixed the silc_server_send_notify_topic_set to really destine
167 the packet to channel. Affected file silcd/packet_send.c.
169 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
170 library. Affected file lib/silcclient/client_notify.c.
172 * Added UMODE announcements. Affected file silcd/server.c.
174 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
176 * Memory leak fixes in:
178 lib/silcutil/silcsockconn.c
179 lib/silcske/silcske.c
182 lib/silccrypt/silcpkcs.c
183 lib/silccore/silccommand.c
184 lib/silccore/silcidcache.c
189 * ROBOdoc documented the lib/silcske/groups.h file and a
190 bit changed the interface for better.
192 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
194 * Update the client entry context in the ID cache after
195 nick change. Affected file lib/silcclient/command.c.
196 Fixes the CUMODE command when regaining founder privileges,
197 and a little WHOIS problem.
199 * Fixed silc_net_gethostbyname to correctly call the
200 inet_ntop. Affected file lib/silcutil/silcnet.c.
202 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
204 * Added IPv6 support checking to the configure.in.pre, added
205 also --enable-ipv6 option to override the check. Affected
206 file configure.in.pre.
208 * The silc_thread_create now calls the start function
209 directly if threads support is not compiled in. Removes
210 ugly #ifdef's from generic code. Affected files are
211 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
213 * Added silc_net_gethostby[name/addr]_async to asynchronously
214 resolve. Affected files are lib/silcutil/silcnet.[ch].
216 * Added support for rendering IPv6 based server, client and
217 channel IDs. Affected file lib/silcutil/silcutil.c.
219 * Added support for creating IPv6 based server IDs. Affected
220 file is silcd/serverid.c.
222 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
224 * Added silc_net_gethostby[addr/name] into the
225 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
226 routines. Added silc_net_is_ip[4/6]. Affected file is
227 lib/silcutil/unix/silcunixnet.c. All routines that take
228 address as argument now supports both IPv4 and IPv6 addresses.
230 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
232 * Fixed LIST command reply sending in server. Affected file
235 * Server now sends the kicker's client ID in the KICK notify
236 to the kicked client. Affected file silcd/command.c.
238 * The client library now parses the kickers client ID and
239 UI displays it. Affected files lib/silcclient/client_notify.c
240 and irssi/src/silc/core/silc-channels.c, module-formats.c.
242 * Made all payload parsing function prototypes consistent.
243 They all take now const unsigned char * and uint32 pair as
244 the payload data instead of SilcBuffer. Changes all around
245 the source tree. Other unsigned char* -> const unsigned char*
246 changes around the tree as well.
248 * Optimized SFTP client and server packet sending not to
249 allocate new buffer for each packet but to recycle the
250 first allocated buffer. Affected files are
251 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
253 * Optimized the SFTP client to use SilcList instead of
254 SilcDList for requests, because it is faster. Affected file
255 is lib/silcsftp/sftp_client.c.
257 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
258 into lib/silccore/silcid.[ch].
260 Renamed silcpayload.[ch] into silcargument.[ch].
262 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
264 * If client entry is deleted with active key agreement
265 session, abort the session.
267 The silc_client_abort_key_agreement now calls the completion
268 callback with new SILC_KEY_AGREEMENT_ABORTED status.
270 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
273 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
275 * Don't use __restrict in older GCC's. Affected file is
276 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
278 * silc_net_localhost now attempts to reverse lookup the
279 IP/hostname. Affected file lib/silcutil/silcnet.c.
281 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
282 command. It can be used to gain founder privileges at
283 the same time when joining the channel.
285 Defined that the SILC_NOTIFY_TYPE_KICKED send the
286 kicker's client ID as well. Updated protocol specs.
288 Defined that the server must send SILC_COMMAND_IDENTIFY
289 command reply with error status to client who sent
290 private message with invalid client ID.
292 Updated the protocol specification.
294 * Added silc_server_send_command_reply to send any
295 command reply. Affected file silcd/packet_send.[ch].
297 * Added silc_id_payload_encode_data to encode ID payload
298 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
300 * The server now send IDENTIFY command reply with error
301 status if client ID in private message is invalid. Affected
302 file silcd/packet_receive.c.
304 * Save the server key file with server's IP address in
305 the filename instead of hostname. The affected file is
306 irssi/src/silc/core/client_ops.c.
308 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
310 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
313 * Added libtool support for compiling shared objects in
314 lib/silcsim. Affected file configure.in.pre and
315 lib/silcsim/Makefile.am. Original patch by cras.
317 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
319 * Pid file configuration, and server's config file fixes
320 patch by toma. Updated CREDITS file.
322 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
324 * Fixed silc_client_channel_message to not try to decrypt
325 the message twice if it resolved the destination client
326 information. This could cause of dropping one channel
327 message. Affected file lib/silcclient/client_channel.c.
329 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
331 * Added silc_client_run_one into lib/silcclient/silcapi.h and
332 lib/silcclient/client.c. This function is used when the SILC
333 Client is run under some other scheduler, or event loop or
334 main loop. On GUI applications, for example this may be
335 desired to used to run the client under the GUI application's
336 main loop. Typically the GUI application would register an
337 idle task that calls this function multiple times in a second
338 to quickly process the SILC specific data.
340 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
342 * Fixed silc_server_drop() for dropping the supplementary
343 groups as well, this could cause a security hole on some
346 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
348 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
351 * Write PID file after dropping privileges. Added -F option
352 to run server on foreground. A patch by debolaz.
353 Affected files silcd/server.c, silcd/silcd.c.
355 * Fixed MOTD to return the MOTD file server name. Affected
356 file silcd/command.c.
358 * Added INFO command reply handling to the Irssi SILC Client.
359 Affected file irssi/src/silc/core/client_ops.c.
361 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
363 * Fixed the silc_idcache_list_* routines to really support
364 the dynamic list. Fixes a crash. Affected file is
365 lib/silccore/silcidcache.c.
367 * Fixed the LIST command reply to really call LIST command's
368 pending callbacks. Affected file silcd/command_reply.c.
370 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
372 * Update conn->local_entry->nickname after giving NICK
373 command. Affected file lib/silcclient/command.c.
375 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
377 * Added the [pid] option to the silcd configuration file
379 Affected files: serverconfig.[ch] and silcd.c
381 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
383 * Save fingerprint in WHOIS command reply in server.
384 Affected file silcd/command_reply.c.
386 * Fixed NICK commands pending callback registration.
387 Affected file lib/silcclient/command.c.
389 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
391 * Use ++server->cmd_ident when sending commands in server,
392 instead of random number. Affected file silcd/command.c.
394 * Fixed GETKEY command reply to call actually GETKEY pending
395 command callbacks. Affected file silcd/command_reply.c.
397 * A bit stricter check for nicknames. Check for same nickname
398 in NICK command also. Affected file silcd/command.c.
400 * Do not call INFO command everytime client ID changes, only
401 during first connecting. Affected file lib/silcclient/client.c.
403 * Set the new nickname only after successful command reply for
404 NICK command is returned by server. Affected file
405 lib/silcclient/command.c.
407 * Remove nicknames from nicklist during server_signoff notify.
408 Should fix /NAMES bit more. The affected file is
409 irssi/src/silc/core/silc-channels.c.
411 * Added `fingerprint' field to the SilcIDListData in the
412 silcd/idlist.h to hold the fingerprint of the client's
415 Send the fingerprint of the client's public key in WHOIS
418 Affected files silcd/command.c, and silcd/idlist.[ch].
420 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
421 create fingerprint from given data.
423 * Show the fingerprint of the client's public key in WHOIS.
424 Affected files irssi/src/module-formats.[ch] and
425 irssi/src/silc/core/client_ops.c.
427 * Format the multiple same nicknames also during JOIN and
428 NICK_CHANGE notifys. Affected file is
429 lib/silcclient/client_notify.c.
431 * Do not print error on screen for invalid private message
432 payload since it can come if someone is sending private
433 messages with wrong key. Affected file
434 lib/silccore/silcprivate.c.
436 * Fixed multiple concurrent /PING crash. Affected file
437 lib/silcclient/command.c.
439 * Changed the wrong ID encoding. All IP addresses must be
440 in MSB first order in encoded format. They were encoded
441 wrong and was in LSB format. Affected files are
442 silcd/serverid.c, lib/silcutil/silcutil.c.
444 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
446 * Call the `connect' client operation through the scheduler
447 in case of error. Affected file lib/silcclient/client.c.
449 * Call the `failure' client operation even if the error
450 occurred locally during a protocol. Affected file is
451 lib/silcclient/protocol.c.
453 * Added support of sending LIST command to router from normal
454 server. This way normal server can get list of all channels
455 in the network too. Fixed the channel list sending in the
456 server too. Affected files are silcd/command.c, and
457 silcd/command_reply.[ch].
459 * Added silc_server_update_channels_by_server and
460 silc_server_remove_channels_by_server. They are used during
461 disconnection of primary router and in backup router protocol.
462 Affected file silcd/server_util.[ch], silcd/server.c and
463 silcd/server_backup.c.
465 * Fixed channel adding to global list in IDENTIFY command
466 reply in server. Affected file silcd/command_reply.c.
468 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
470 * If the incoming packet type is REKEY or REKEY_DONE process
471 that packet always synchronously. Fixes yet another MAC
472 failed error on slow (dialup) connections. Affected file
473 lib/silcclient/client.c and silcd/server.c.
475 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
477 * Call check_version SKE callback for initiator too. Affected
478 file lib/silcske/silcske.c.
480 * Implemented fix for security hole found in the SKE that was
481 fixed in the specification few days back; the initiator's
482 public key is now added to the HASH value computation.
483 Added backwards support for the old way of doing it too, for
484 old clients and old servers. Affected file is
485 lib/silcske/silcske.c.
487 * Enabled mutual authentication by default in SKE. If initiator
488 is not providing mutual authentication the responder will
489 force it. This will provide the proof of posession of the
490 private key for responder. The affected files are
491 lib/silcclient/protocol.c and silcd/protocol.c.
493 * Do not cache anymore the server's public key during SKE.
494 We do mutual authentication so the proof of posession of
495 private key is done, and if the server is authenticated in
496 conn auth protocol with public key we must have the public
497 key already. Affected file silcd/protocol.c.
499 * Added new global debug variable: silc_debug_hexdump. If
500 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
501 file lib/silcutil/silclog.[ch].
503 * Fixed compilation warning due to char * -> const char *.
504 Affected files lib/silcutil/silcnet.h, and
505 lib/silccore/silcauth.[ch].
507 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
509 * Fixed CMODE command when new channel key was created. If
510 the creation failed the old key was removed. Next time giving
511 same command would crash the server since the old key was
512 freed already. Affected file silcd/command.c.
514 * Fixed the silc_server_announce_get_channels to not crash
515 on reconnect. Affected file silcd/server.c.
517 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
519 * Added silc_log_set_debug_string function to set a regex
520 string to match for debug output. Only the function names,
521 or filenames matching the given debug string is actually
522 printed. This way it is possible to filter out those debug
523 strings that user is not interested in.
525 Fixed a bug in silc_string_regexify.
527 Affected files lib/silcutil/silclog.[ch], and
528 lib/silcutil/unix/silcunixutil.c.
530 * Changed the -d options in both server and Irssi SILC client
531 to take the debug string as argument. Affected files
532 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
534 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
536 * Added silc_hash_babbleprint to create a Bubble Babble
537 Encoded fingerprint. The encoding is developed by Antti
538 Huima (draft-huima-babble-01.txt), and it creates human
539 readable strings out of binary data. Affected file
540 lib/silccrypt/silchash.[ch].
542 * Print the babble print now in addition of fingerprint as well
543 in Irssi SILC client. Affected files are
544 irssi/src/fe-common/silc/module-formats.[ch],
545 irssi/src/fe-common/silc/core/client_ops.c.
547 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Fixed a security problem found in SKE. The initiator's
550 public key too is now added to the HASH hash value creation
551 which is signed by the responder to create the SIGN value.
552 This will prevent anyone in the middle to lie to the responder
553 about the initiator's public key. If this is done now, the
554 man in the middle will get caught. Updated the protocol
557 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
559 * Better installation directory handling. Configure module
560 paths and other paths automatically to example_silc* files
561 in doc/. A patch by toma.
563 * Fixed compiler warning from MPI library, and from SILC RNG.

593 * Added silc_pkcs_public_key_compare to compare two
594 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
596 * Check that the client who set the founder mode on the
597 channel is the same client that is giving the founder
598 mode to itself. It is done by comparing the saved public
599 key (it is saved even in the authentication is passphrase).

608 client library. Affected file lib/silcclient/client.c.
610 * Fixed the silc_client_packet_parse to not to increase
611 the packet sequence number if the conn->sock and the
612 current socket connection is not same. This can happen
613 for example during key agreement when the conn includes
614 multiple socket connections (listeners). Affected file
615 lib/silcclient/client.c.
617 * The sender of the file transfer request now provides also
618 the pointer (listener) for the key exchange protocol. If
619 the listener cannot be created then it sends empty key
620 agreement and lets the receiver provide the listener.
622 Added `local_ip' and `local_port' arguments to the
623 silc_client_file_send. If they are provided they are used,
624 if not then it will attempt to find local IP address, if
625 not found or bind fails then the remote client will provide
628 Affected files are lib/silcclient/client_ftp.c and
629 lib/silcclient/silcapi.h.

638 of the client's public key (if the proof of posession of the
639 corresponding private key is verified by the server).
640 Updated to the protocol specification.
642 * Added support of receiving the client's public key's
643 fingerprint in command reply in client library. Affected
644 file is lib/silcclient/command_reply.c, and

703 during SERVER_SIGNOFF, but invalidate it. This way we
704 preserve the WHOWAS info for the client. Affected file
707 * Fixed SERVER_SIGNOFF notify handling in the server. The
708 server is now able to process incoming SERVER_SIGNOFF notify
709 for a server that it doesn't even know about. It will remove
710 the clients provided in the notify. Affected file
711 silcd/packet_receive.c.
713 * Check for partial packet in data queue after every packet that
714 was found from the queue. Return and wait for more data if
715 there is partial data in queue. Affected file is

740 available. It is used in padding generation. Affected file
741 lib/silccrypt/silcrng.[ch].
743 * All packets in client library are now processed synchronously.
744 Optimized packet processing a lot. Affected file
745 lib/silcclient/client.c.
747 * All server connection packets are processing synchronously
748 now in server, to optimize packet processing. Affected file
751 * Include files are installed now only in Toolkit distribution
752 if make install is given. Affected files: all Makefile.am's.
754 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
756 * Assure that silc_client_notify_by_server_resolve does not
757 resolve the client information multiple times. If it cannot
758 be found by the first it cannot be found at all. Affected
759 file lib/silcclient/client_notify.c.
761 * Fixed WHOWAS command reply calling. Affected file
762 lib/silcclient/command_reply.c.
764 * Removed all references to silc_idlist_get_client from the
765 Irssi SILC client since that call is internal call used by
766 the library. The Irssi SILC client will use now client
767 retrieval functions found in silcapi.h.
769 * Fixed a bug in resolving nickname info before sending
770 private message. It used freed memory. Affected file
771 irssi/src/silc/core/silc-servers.c.
773 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

793 Affected file lib/silcutil/silcnet.[ch].
795 * If key exchange or rekey protocol is active for a connection
796 parse all packets syncronously since there might be packets
797 in packet queue that we are not able to process without first
798 processing packets before them. Affected file silcd/server,
799 lib/silcclient/client.c.
801 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
802 whether library should continue processing the packet.

887 length. Affected file lib/silccore/silcpacket.[ch].
889 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
890 length for maximum padding up to 128 bytes). Affected
891 file lib/silccore/silcpacket.h.
893 * Removed all backwards support for old 0.5.x MAC thingies.
894 The SILC packet header change makes it impossible to be
895 backwards compatible.
897 * Send the ENDING packet with timeout in the backup resuming
898 protocol. This is to assure that all routers has connected
899 to the primary router. Affected file silcd/server_backup.c.
901 * Changed the RNG to take the first IV from random data. It
902 used to take it from zero actually. Changed the RNG also
903 to use /dev/urandom during session. /dev/random is used

909 (the packet length) encrypted. Affected files aroung the
910 code tree, lib/silccore/silcpacket.[ch]. Removed the
911 SilcPacketCheckDecrypt callback. It is not needed anymore
912 since the silc_packet_receive_process will determine now
913 whether the packet is normal or special.
915 * Implemented the unidirectional MAC keys. Affected files
916 lib/silcske/silcske.c, silcd/protocol.c and

926 * Allow backup router to announce servers. All servers
927 announced by backup router are added to the global list
928 automatically. Update hte server's socket to our primary
929 router also when backup router announces a server.
930 Affected file silcd/packet_receive.c.
932 * Do not update the client->router in the function
933 silc_server_udpate_clients_by_server if the client is on
934 global list. We might fail to find any specific server
935 for locally connected clients and local cell clients. They
936 should still use the `from' and not `to' as client->router.
937 This fixes backup router resuming protocol. Affected file
940 * Decrease channel statistics count only if the channel
941 deletion worked. Affected files are silcd/server.c and

980 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
981 Affected file silcd/packet_send.c.
983 * Changed the SFTP Filesystem interface. Changed the
984 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
985 the filesystem operation function. The SilcSFTPFilesystem
986 is now a context that is allocated by all filesystem allocation
987 functions and it already includes the operations structure
988 and filesystem specific context. It is given as argument
989 now to the silc_sftp_server_start. This made the interface
990 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
991 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
993 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
995 * Changed the backup router adding and getting interfaces
996 in the server. The router that will be replaced by the
997 specified backup router is now sent as argument. Affected

1113 new packet type SILC_PACKET_FTP and defined File Transfer
1114 Payload. The mandatory file transfer protocol is SFTP
1115 (SSH File Transfer Protocol). Affected file in addition
1116 of the internet draft is lib/silccore/silcpacket.h.
1118 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1119 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1120 is used as part of backup router protocol when the primary
1121 router of the cell is back online and wishes to resume
1122 the position as primary router.
1124 * Redefined the MAC generation keys in the protocol. The
1125 same key is not used anymore in both direction. Both
1126 direction will now use different keys for sending and
1127 receiving. This fixes a potential security flaw. This
1128 change causes incompatibilities in the protocol.
1130 * Redefined also the MAC computation from the packet.
1131 An packet sequence number is now added to the MAC
1132 computation. This prevents possible replay attacks against
1133 the protocol. This change too causes incompatibilities
1136 Added `sequence' field to the SilcPacketContext to hold
1137 the current sequence number for the packet.
1139 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1141 * Added `created' field to the SilcIDListData in the file
1142 silcd/idlist.h to indicate the time when the entry was
1145 * Added `created' field to the SilcChannelEntry too. Affected
1146 file silcd/idlist.h.
1148 * Added `creation_time' aguments to all the announcement functions
1149 in the server. If it is provided then only the entries that
1150 was created after the provided time frame are actually
1151 announced. Affected file silcd/server.[ch].
1153 * The protocol says that the Channel ID's IP address must be
1154 based on the router's IP address. Added check for this in
1155 the silc_server_new_channel when processing incoming New Channel
1156 Payload. Affected file silcd/packet_receive.c.
1158 * Print out the correct version with --version in SILC client.
1159 Affected file irssi/src/silc/core/silc-core.c.
1161 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1163 * Fixed WHOWAS command to check for completnes of the client
1164 entry always, not just when the command is coming from client.
1165 Affected file silcd/command.c.
1167 * Added new function silc_server_packet_queue_purge to purge the
1168 outgoing data queue to the network. After the function returns
1169 it is guaranteed that the outgoing packet queue is empty.
1170 Affected file silcd/packet_send.[ch].
1172 * Purge the outgoing packet queue in the rekey protocol's final
1173 callback to assure that all rekey packets go to the network
1174 before quitting the protocol. Affected file silcd/server.c.
1176 * Added silc_client_packet_queue_parse as similar function as
1177 in server to the client library. The affected file is
1178 lib/silcclient/client.c.
1180 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1182 * Splitted silcd/server.c and created silcd/server_util.[ch]
1183 for utility functions.
1185 * Added new socket flag SILC_SF_DISABLED to indicate that the
1186 connection is open but nothing can be sent to or received from
1187 the connection. Affected file lib/silcutil/silsockconn.[ch].
1188 The checking for disabled socket is checked in the low level
1189 silc_socket_write and silc_socket_read functions.
1191 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1193 * Allow only nicknames and channel names that fits into the
1194 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1196 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1198 * When processing JOIN command reply in server check that if
1199 the channel exists in our global list we'll move it the local
1200 list. Affected file silcd/command_reply.c.
1202 * Fixed the check whether client is joined on the channel already
1203 in JOIN command. Affected file lib/silcclient/command.c.
1205 * Fixed the JOIN command reply to check whether the channel
1206 already exists. Affected file lib/silcclient/command_reply.c.
1208 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * Added silc_ske_status_string to map the SKE error numbers
1211 to readable strings. The affected files are
1212 lib/silcske/silcske[_status].[ch].
1214 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1216 * Do not show the private channels on the WHOIS channel list
1217 as it is not allowed by the protocol. The affected file is
1220 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1222 * Assure that the packet length digged from the actual packet
1223 is something sensible in the silc_packet_decrypt_rest_special
1224 in lib/silccrypt/silcpacket.c.
1226 * Free and NULL the allocated pointer in silc_hmac_alloc if
1227 the HMAC allocation fails. The affected file is
1228 lib/silccrypt/silchmac.c.
1230 * Print the selected security properties to the log files in
1231 the server. Affected file silcd/protocol.c.
1233 * Add SKE's reference counter even if calling the completion
1234 callback manually. Otherwise it goes negative, although it
1235 does not cause any problems. The affected file is
1236 lib/silcske/silcske.c.
1238 * Remove the client entry with short timeout after giving the
1239 KILL command. Affected file lib/silcclient/command.c.
1241 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1242 case all found clients are already disconnected (WHOWAS would
1243 found them) in the server. Affected file silcd/command.c.
1245 * Update the last_receive (time of last data received) to be
1246 updated only when received private or channel message so that
1247 the idle time showed in WHOIS makes more sense.
1249 * Added boolean field `valid' in to the SilcClientEntry in the
1250 client library to indicate whether the entry is valid or not.
1251 This fixes the nickname change bug on channel when changing
1252 the nickname to be same than the old (like nick to Nick) the
1253 nickname formatter doesn't set the new nick anymore to Nick@host.
1254 Affected file lib/silcclient/idlist.[ch].
1256 * Now actually fixed the nickname changing on disconnection.
1257 Added new function silc_change_nick to the Irssi SILC Client.
1258 Affected file irssi/src/silc/core/client_ops.c,
1259 irssi/src/silc/core/silc-nicklist.[ch].
1261 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Check that the public key exists in the GETKEY command before
1264 trying to encode it. Affected file silcd/command.c.
1266 * Print some notifications on received public keys with GETKEY
1267 command in the Irssi SILC Client. Affected files are
1268 irssi/src/fe-common/silc/module-formats.[ch],
1269 irssi/src/silc/core/client_ops.c.
1271 * Use IDENTIFY command to resolve the server information in the
1272 GETKEY command instead of INFO command. Affected file
1273 lib/silcclient/command.c.
1275 * All command reply functions in the client library now calls
1276 the pending command reply callbacks even if an error has
1277 occurred. The server has done this a long time and now it was
1278 time to move the client library to this as well. Now all
1279 errors can be delivered back to the pending command reply
1280 callbacks if necessary. Affected files are
1281 lib/silcclient/command[_reply].[ch].
1283 * Change the nickname on disconnection back to the username
1284 because in reconnect the server will enforce it to it anyway.
1285 Affected file irssi/src/silc/core/silc-servers.c.
1287 * Fixed a config file parsing bug in the Irssi SILC client.
1288 Affected file irssi/src/silc/core/clientconfig.c.
1290 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1292 * When printing the channel mode on JOIN, verify that the
1293 channel key and channel's HMAC are valid. Affected file
1294 irssi/src/silc/core/client_ops.c.
1296 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1298 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1299 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1300 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1302 * Removed channel key rekey task deleting from the function
1303 silc_server_save_channel_key. Affected file silcd/server.c.
1304 Added explicit timeout task context instead that is used to
1305 delete the task if we are registering a new task before the
1306 new task has elapsed.
1308 * When channel key rekey occurs the client library now saves
1309 the old channel key for a short period of time (10 seconds) and
1310 is able to use it in case some is still sending channel
1311 messages encrypted with the old key after the rekey. Affected
1312 file lib/silcclient/[idlist.h|client_channel.c].
1314 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1316 * Added check to the silc_server_new_id_real to not accept
1317 new ID if it is the sender's own ID. Affected file is
1318 silcd/packet_receive.c.
1320 * Assure that we do not announce ourself or the one we've
1321 sending our announcements when we're router and are announcing
1322 servers to our primary router. Affected file silcd/server.c.
1324 * Fixed silc_server_command_identify_check_client to assemble
1325 correct WHOIS packet. It send corrupted WHOIS packet and
1326 caused problem with router to router connections. Affected
1327 file silcd/command.c.
1329 Fixed also silc_server_command_whois_check the same way
1330 as for the IDENTIFY command.
1332 * Added new SilcIDListStatus to the server in the SilcIDListData
1333 structure. The status now includes the current status of
1334 the entry (like registered, resolved etc.). Affected file
1335 silcd/idlist.[ch]. Defined a bunch of different status types
1336 as well. This replaced the old boolean registered field as well.
1338 Added resolve_cmd_ident field to the SilcClientEntry structure
1339 too so that if the entry is for example being resolved so
1340 another command may attach to the same pending command reply
1341 without requiring to resolve the same entry again. This concept
1342 should optimize the WHOIS and the IDENTIFY resolving under
1343 heavy load by taking away unnecessary resolving for entries
1344 that are being resolved already.
1346 Added support for adding multiple pending commands for one
1347 command idenfier. Affected file silcd/command[_reply].[ch].
1349 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1350 before deleting the data. Otherwise the hash table will have
1351 freed data in comparison functions. Affected file is
1352 silcd/command_reply.c.
1354 * Fixed silc_idlist_replace_client_id to add the new entry to
1355 the cache with NULL nickname. Otherwise there will be invalid
1356 memory as the nickname after the nickname is freed. Affected
1357 file silcd/packet_receive.c.
1359 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1360 saved into wrong slots because the previous number of entries
1361 was not taken into account. Affected file silcd/idlist.c.
1362 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1364 * If we are router and we receive JOIN notify to a channel that
1365 does not have any users then notified client is marked as the
1366 channel founder, as it is it. The affected file is
1367 silcd/packet_receive.c
1369 * Added to the extended hash table API's table_del_*ext functions
1370 the destructor as argument too, so that the caller can decide
1371 which destructor to use or whether to use destructor at all.
1372 Affected file lib/silcutil/silchashtable.[ch].
1374 * Fixed ID Cache purging. It actually deleted the entries from
1375 the hash table after the data was freed. The hash table ended
1376 up comparing freed memory. The affected file is
1377 lib/silccore/silcidcache.c.
1379 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Fixed Irssi SILC client's KILL command's HELP syntax.
1383 * The USERS command now resolves the detailed user information
1384 if the userinfo field is missing. Affected file is
1385 lib/silcclient/command_reply.c.
1387 * Do not print error in silc_file_read if the read file does
1388 not exist. Just silently return NULL. Affected file is
1389 lib/silcutil/silcutil.c.
1391 * Fixed the silc_log_output to not wine about NULL filename
1392 and to not create some bogus " " filename. Affected file is
1393 lib/silcutil/silclog.c.
1395 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1397 * Fixed various printing bugs on the user interface in the
1398 Irssi SILC Client. Minor changes that were forgotten from
1401 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1403 * Fixed the configure.in.pre and the compilation and distribution
1404 environment to support the new autoconf 2.52. That version is
1405 now required to compile the CVS trunk.
1407 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1410 to generally parse user@fqdn format strings. Affected file
1411 lib/silcutil/silcutil.c.
1413 * Added nickname_format and nickname_force_format fields to the
1414 SilcClientParams structure. The first one defines the format
1415 for the nicknames that the library will enforce if the receives
1416 multiple same nicknames. The second one is boolean value and
1417 can be used to force the library to always enforce the format
1418 to the nicknames regardles whether there are multiple nicknames
1419 or not. This configurable formatting was employed to flexibly
1420 support accessing multiple nicknames from the user interface.
1421 The userinterface can now set the nicknames to what ever format
1422 they prefer. Affected file lib/silcclient/silcapi.h.
1424 Added function silc_client_nickname_format to the file
1425 lib/silcclient/idlist.c. It performs the nickname formatting.
1427 Added new field `hostname´ to the SilcClientEntry context.
1428 It holds the hostname of the client. Affected file is
1429 lib/silcclient/idlist.h.
1431 * Irssi SILC Client sets the nicknames in nick@hostn format.
1432 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1433 irssi/src/silc/core/silc-core.c.
1435 The WHOIS printing now also shows both the real nickname and
1436 the formatted nickname so that user knows how to access the
1437 user if there are multiple same nicknames cached. Affected
1438 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1439 printing formatting too to take the hostname now as a separate
1440 argument. The Affected file is
1441 irssi/src/fe-common/silc/modules-formats.[ch].
1443 * Changed the silc_client_get_clients_local to accept the formatted
1444 nickname as argument. It accepts the real nickname too but the
1445 formatted nickname can be used to find the true entry from
1446 multiple entries. Affected file lib/silcclient/silcapi.h and
1447 lib/silcclient/idlist.c.
1449 * Added nickname_format_parse field to the SilcClientParams.
1450 It is a callback function provided by the application to parse
1451 the nickname out of the formatted nickname string. The library
1452 calls it to get the nickname from the formatted string. Since
1453 the application generally knows better the format of the nickname
1454 string it parses it instead of the library, even though library
1455 encodes the formatted string. If the callback function is not
1456 provided then the library will use the string as is. The
1457 affected file is lib/silcclient/silcapi.h.
1459 * All the nickname strings passed to the client library in
1460 commands are now expected to be formatted nickname strings.
1461 If the command does not support the formatted nickname string
1462 it will assume that the sent string is the actual nickname.
1463 Affected file lib/silcclient/command.c.
1465 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1467 * Added public key authentication support to OPER and SILCOPER
1468 commands in the client library. Affected file is
1469 lib/silcclient/command.c.
1471 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Changed the get_auth_methdod client operation to be asynchronous.
1474 It can be async if the application resolves the authentication
1475 method from the server during the negotiation. Added new
1476 SilcGetAuthMeth completion callback that the application will
1477 call after resolving the authentication method.
1479 Added function silc_client_request_authentication_method that
1480 the application can use to resolve the authentication method
1481 from the server. Added also SilcConnectionAuthRequest callback
1482 that the library will call after the server has replied. The
1483 application can call this function if it does not know the
1484 current authentication method.
1486 Affected files are lib/silcclient/client.c and
1487 lib/silcclient/silcapi.h.
1489 * The Irssi SILC client now automatically resolves the authentication
1490 method incase any configuration information is not present (and
1491 currently there never is). The affected file is
1492 irssi/src/silc/core/client_ops.c.
1494 * Fixed public key authentication from the client library.
1495 Affected file lib/silcclient/protocol.c. Changed also the
1496 protocol specification about the public key authentication in
1497 the connection authentication protocol. The actual data to be
1498 signed is now computed with a hash function before signing.
1500 * Fixed the public key authentication from the server as well.
1501 Affected file silcd/protocol.c.
1503 * Removed the mlock()'s from the memory allocation routines.
1504 Affected file lib/silcutil/silcmemory.c. The ./configure does
1505 not check anymore for the mlock(). Affected file is
1508 * Fixed USERS command in server to allow the execution of the
1509 command for private and secret channels if the client sending
1510 the command is on the channel. Affected file silcd/command.c.
1512 * Fixed silc_client_get_clients_local to return the clients
1513 count correctly. It could return wrong value. Affected file
1514 lib/silcclient/idlist.c.
1516 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1518 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1519 types. The assembler optimizations seemed not to like 64-bit
1520 data types. The assmebler optimizations thus are now enabled
1521 also for BSD systems as opposed to only enable them for Linux.
1523 * Do not check for threads at all on BSD systems. Affected
1524 file configure.in.pre.
1526 * Removed -n and -h options from the Irssi SILC Client since
1527 they are not used in silc.
1529 * Fixed the prime generation to assure that the first digit
1530 of the generated random number is not zero since our conversion
1531 routines does not like number strings that starts with zero
1532 digit. If zero digit is seen the random number is regenerated.
1533 This caused some corrupted RSA keys when the zero first digit
1534 was met. Affected file lib/silcmath/silcprimegen.c.
1536 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Fixed WIN32 configuration in the ./configure script.
1539 Fixed to include xti.h on environments that has it.
1540 Patches by Carsten Ilchmann and andrew.
1542 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Changed the silc_id_create_client_id to be collision
1545 resistant. It is now assured that there cannot be created
1546 two same client ID's. I suspect that some weird bugs in
1547 the server were actually caused by duplicate Client IDs.
1548 Affected file silcd/serverid.[ch]. A router receiving
1549 new ID now also assures and informs the sending server
1550 if the ID caused collision.
1552 * Changed the silc_id_create_channel_id to also assure that
1553 there are no collisions.
1555 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1557 * Statement about ignoring the Mutual Authentication flag when
1558 performing rekey with PFS was a bit misleading. It is ignored
1559 if it was set in the initial negotiation, it cannot be even
1560 set in the rekey. Fixed in the ke-auth draft. Started the
1561 new versions of the protocol drafts in the doc/.
1563 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Fixed a bug in silc_client_command_identify_save when saving
1566 new channel information. The channel name was no duplicated
1567 and caused crash on exit. Affected file is
1568 lib/silcclient/command_reply.c.
1570 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Fixed the getkey command handling in the server. Send just
1573 empty OK reply to the sender if the key could not be fetched
1574 (but everything else was ok, like the key just was not available).
1575 Changed the public key parameter to optional in the protocol
1576 specs so that empty OK reply can be sent. Affected file
1579 Added a message to Irssi SILC client to tell to user if the
1580 server did not return a public key.
1582 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Fixed a channel key regeneration bug. It registered new
1585 timeout tasks exponentially until all system resources were
1586 used. Affected file silcd/server.c.
1588 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1590 * Added the SILC Document generator to the scripts/silcdoc.
1591 It can be used to generate the Toolkit Reference Manual out
1592 of the source tree. Internally it will also use the RoboDoc
1593 generator now imported in util/robodoc.
1595 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1597 * Added couple of return's in rekey protocol if error orccurred
1598 during the protocol. The execution must be terminated.
1599 Affected file silcd/protocol.c. Also, terminate the protocol
1600 always with timeout.
1602 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1604 * The client's Client ID was created initally from the wrong
1605 nickname (it could have been in format nick@host) in the
1606 silc_server_new_client. Affected file silcd/packet_receive.c
1608 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1610 * Added some SILC_LOG_ERROR's to various error conditions
1611 if client could not be added to ID cache. Affected files
1612 silcd/packet_receive.c and silcd/server.c.
1614 * When client's sock->user_data is freed, NULL also the
1615 client->router and client->connection pointers. Added check
1616 for these pointers being NULL to various places around the
1617 code. Affected file silcd/server.c.
1619 * Added client->data.registered == TRUE checks to various
1620 places around the code to assure that unregistered client's
1621 are not handled when it is not allowed. Affected file
1624 * Added `bool registered' fields to all
1625 silc_idlist_[server|client]_get_* routines to indicate whether
1626 the fetched client needs to be registered or not. Affected
1627 file silcd/idlist.[ch].
1629 * Add your own entry as registered to the ID cache in the
1630 server. Affected file server.c.
1632 * Fixed a bug in silc_server_new_server. The SilcServer was
1633 set as the new server's context instead of SilcServerEntry.
1634 This naturally caused some weird bugs.
1636 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1638 * Do not delete the channel rekey task when adding it
1639 for in silc_server_create_channel_key.
1641 * Changed the silc_server_create_channel_key to return
1642 TRUE or FALSE to indicate the success of the channel key
1645 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Fixed MSVC++ project files and added missing files to

1657 file irssi/src/fe-common/core/themes.c.
1659 * Fixed double free in client library in the file
1660 lib/silcclient/client.c when disconnecting from server.
1662 * Applied double free patch from cras to Irssi SILC client.
1663 Affected files irssi/src/core/[modules/expandos].c
1665 * Fixed the disconnection handling to Irssi SILC Client.
1666 The application must call silc_client_close_connection
1667 in ops->connect client operation in case of failure of
1668 the connection. Affected file is
1669 irssi/src/silc/core/client_ops.c.
1671 * Do not set sock->protocol to NULL in the function
1672 silc_client_close_connection after executing the protocol's
1673 final callback since the sock might not be valid anymore.
1674 Affected file lib/silcclient/client.c.
1676 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Do not enable SILC_THREADS if the linking with libpthread
1679 did not happen. Affected file configure.in.pre.
1681 * Added notion to protocol specification that server must
1682 verify the sent authentication payload with CMODE when
1683 setting the channel founder key. Implemented it to the
1684 server. Affected file silcd/command.c.
1686 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Added _EXTRA_DIST SILC distribution variable to the
1689 distributions file. It is used to conditionally add extra
1690 files or directories to the specific distribution. Affected
1691 files ./prepare, Makefile.am.pre and distributions.
1693 Removed the `_' from the start of the distribution names.
1696 * Added README.WIN32 for instructions to compile the Toolkit
1699 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Fixed a double free in disconnection in the server. Affected
1702 file is silcd/server.c.
1704 * Fixed the lib/silcske/groups.c to work now also with GMP
1705 MP library. The string conversion did not work when using
1706 specific base and the base is indicated in the string as well.
1708 * Created win32/ directory which now includes MSVC++ specific
1709 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1710 It will appear only in the toolkit distribution
1712 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Changed the key material distribution function in case when
1715 the hash output is too short. The data is now concatenated
1716 a bit differently than it used to. Made the change to the
1717 SKE protocol specification.
1719 * Added better GMP detection to configure.in.pre. A patch
1722 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Fixed a minor bug in SKE that might cause some problem on
1725 some platforms. Affected file lib/silcske/silcske.c.
1727 * Added the cookie checking for initiator in the SKE. It checks
1728 that the responder returns the sent cookie unmodified. The
1729 affected file is lib/silcske/silcske.c. Added new SKE
1730 error type INVALID_COOKIE that can be sent during the
1731 negotiation. Fixed some memory leaks as well.
1733 * Added the "invalid cookie" error message to Irssi SILC client's
1736 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Added `task_max' field to the SilcClientParams to indicate
1739 the maximum tasks the scheduler can handle. If set to zero,
1740 default values are used. Affected file lib/silcclient/silcapi.h.
1742 * Fixed memory leaks in silc_client_close_connection. Affected
1743 file lib/silcclient/client.c.
1745 * Added silc_client_del_client_entry to client library to free
1746 all memory of given client entry. Affected file is
1747 lib/silcclient/idlist.[ch].
1749 * Added new functions silc_client_del_channel and
1750 silc_client_del_server to delete channel and server entries.
1751 Affected file lib/silcclient/[silcapi.h/idlist.c].
1753 * Removed silc_client_del_client_by_id from silcapi.h.
1755 * Fixed the INFO command to return the server's own info
1756 correctly when querying by Server ID. Affected file is
1759 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1761 * Removed the non-blocking settings in WIN32 code in the
1762 silc_sock_[read/write] and added SleepEx instead. Affected
1763 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1764 of input data is now checked with FIONREAD and ioctlsocket.
1766 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Call silc_schedule_task_del_by_context in the
1769 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1770 Affected file lib/silccore/silcprotocol.c.
1772 * Call silc_protocol_cancel for active protocols in the
1773 silc_server_close_connection if the funtion
1774 silc_server_free_sock_user_data has not been called.
1775 Affected file silcd/server.c.
1777 * Generic tasks cannot be deleted using the del_by_fd
1778 task deleting function since generic tasks does not match
1779 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1781 * Added a notion to SILCOPER help file that the SILCOPER works
1782 only on router server, not on normal server.
1784 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1786 * Added for WIN32 support for the new scheduler as well.
1787 Affected file lib/silcutil/win32/silcwin32schedule.c.
1789 * Fixed the SHA1 implementation to work on various platforms.
1791 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1793 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1794 API. It is part of the scheduler now. Everything else is
1795 as previously but some functions has changed their names.
1796 Checkout the lib/silcutil/silcschedule.h for the interface.
1797 Updated all applications to use the new interface. Affected
1798 files are lib/silcutil/silcschedule.[ch].
1800 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1802 * Found a bug in the SKE implementation. The HASH value,
1803 specified by the protocol, was not computed correctly. The
1804 public key of the responder was not added to the computation
1805 even though it is mandatory. Affected file lib/silcske/silcske.c.
1806 This unfortunately causes incompatibilities with older
1807 clients and servers.
1809 * Added WIN32 specific network init and uninit functions:
1810 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1811 the Winsock2. Affected file lib/silcutil/silcnet.h and
1812 lib/silcutil/win32/silcwin32net.c.
1814 * Set the socket always to nonblocking mode on WIN32 after
1815 reading data or writing data. Affected file is
1816 lib/silcutil/win32/silcwin32sockconn.c.
1818 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Fixed various compilation problems under WIN32. Affected
1821 files lib/silcutil/win32/silcwin32thread.c and
1822 lib/silcutil/win32/silcwin32schedule.c.
1824 * Removed all _internal.h #includes from public header
1825 files. Internal headers must never be included from
1828 Removed also the lib/silcske/payload_internal.h file.
1830 * All include files that may be needed (public and some others
1831 included by the public headers) by application developers are
1832 now copied to the ./includes directory. It does not copy any
1833 internal headers. Affected file Makefile.defines.pre and all
1834 Makefile.am's under lib/ and subdirs.
1836 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Do not change the ~/.silc directory's permissions automatically.
1839 Affected file irssi/src/silc/core/clientutil.c.
1841 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Do not cancel the protocol in silc_server_close_connection
1844 it might cause recursion. Now cancelled in the function
1845 silc_server_free_sock_user_data. Affected file silcd/server.c.
1847 * Fixed the silc_server_remove_clients_by_server to regenerate
1848 the channel keys correctly finally. Added also new function
1849 silc_server_remove_clients_channels to actually do it.
1850 Affected file silcd/server.c.
1852 * Fixed the silc_server_new_channel to not crash by giving
1853 wrong router to the new channel. Affected file is
1854 silcd/packet_receive.c.
1856 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1859 which is given as argument to the silc_client_alloc now.
1860 It can be used to configure the client and set various parameters
1861 that affect the function of the client.
1863 * The USERS command in server did not check whether the channel
1864 is private or secret. Affected file silcd/command.c.
1866 * Added new argument to the USERS command in protocol specification.
1867 The USERS command now can take the channel name as argument
1868 as well. Added support for this in client and server and
1869 updated the protocol specs.
1871 * Completed the GETKEY command in client. It can be now used
1872 to fetch also servers public key not only some clients.
1873 Affected files lib/silcclient/command[_reply].c.
1875 * Added silc_client_get_server to return server entry by the
1876 server name. Affected files lib/silcclient/silcapi.h and
1879 * Redefined the IDENTIFY command in protocol specification to be
1880 more generic. It now can be used to query information about
1881 any entity in the SILC Network, including clients, servers and
1882 channels. The query may be based either the entity's name
1883 or the ID. Added support for this in both client and server.
1885 Affected files silcd/command.c and lib/silcclient/command.c
1886 and command_reply.c.
1888 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1889 the _from_client and _from_server functions. Affected file
1892 * Added silc_client_get_channel_by_id_resolve to the file
1893 lib/silcclient/silcapi.h to resolve channel information by
1894 its ID. Added also silc_client_get_channel_by_id that
1895 does not resolve it from the server.
1897 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Added SilcServerEntry context into the client library
1900 to represent one server. The INFO command now allocates
1901 these to save the resolved server info. For now on the
1902 client library will also keep information about servers,
1903 connected and resolved with INFO.
1905 The INFO command now allocates the SilcServerEntry context
1906 and saves the server info there. The COMMAND_REPLY in
1907 the INFO now returns the parameters to application in
1908 same order as defined in the protocol specification.
1910 The entries are cached in the client->server_cache.
1912 * The INFO command is now issued after received the Client ID
1913 from the server. Affected file lib/silcclient/client.c.
1915 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1916 to the application as the mode changer might be server.
1917 It is guaranteed that NULL is not returned anymore to the
1918 application. Affected file lib/silcclient/client_notify.c.
1920 The ID Type is now also passed to the application so that
1921 it can check whether the returned entry is SilcClientEntry
1924 Added new function silc_client_get_server_by_id to return
1925 the server entry by ID. Affected files are the
1926 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1928 * Do not create the channel in the Irssi SILC Client when issuing
1929 the JOIN command but when received the sucessful JOIN command
1930 reply. Otherwise the channel might get created even though we
1931 could not join it. The Affected file is
1932 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1934 * Fixed a channel joining bug in router. The router must also
1935 check the channel modes, invite and ban lists etc. when serving
1936 the JOIN command sent by normal server. Affected file is
1937 silcd/command.c. The router now resolves the client's
1938 information from the server who sent the JOIN command if it
1939 does not know it, and processes the JOIN command only after
1942 * Changed the SilcCommandCb to take new argument; void *context2.
1943 Affected file lib/silccore/silccommand.h
1945 The second argument in the command callbacks in the server now
1946 includes the SilcServerCommandReplyContext if the command was
1947 called as pending command callback from the command reply.
1948 Otherwise it is NULL. When called as pending the status of the
1949 command reply will be checked and if it was erronous the
1950 error will be sent to the original sender of the command.
1951 This way the client always receives the error messages even
1952 though the server was actually the one who received the error
1953 when it resent the command to router, for example. Affected
1954 files silcd/command[_reply].[ch].
1956 * Fixed sending WHOWAS command's error message to client if
1957 the requested client could not be found. It was missing.
1960 * Changed the CMODE and CUMODE commands reply arguments in the
1961 protocol specification. The Channel ID is now sent in both
1962 of the commands to identify the channel. Implemented this
1963 new feature to the client and server. Affected files
1964 lib/silcclient/command_reply.c and silcd/command.c.
1966 * Made better checks for invite and ban lists in the JOIN
1967 command in server. Affected file silcd/command.c.
1969 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * The server now performs the incoming host IP/DNS lookup
1972 using the silc_socket_host_lookup and thus does not block
1973 the server anymore. Affected file silcd/server.c.
1975 * Completed the multi-thread support for SILC Scheduler in
1976 the lib/silcutil/silcschedule.c.
1978 * Fixed the configure.in.pre to detect the pthread correctly
1981 * Fixed a deadlock in silc_task_queue_wakeup in the file
1982 lib/silcutil/silctask.c.
1984 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1986 * Added new function silc_schedule_wakeup that is used in
1987 multi-threaded environment to wakeup the main thread's
1988 schduler. It needs to be used when a thread adds a new task
1989 or removes a task from task queues. After waking up, the
1990 scheduler will detect the task queue changes. If threads
1991 support is not compiled in this function has no effect.
1992 Implemented the wakeup mechanism to both Unix and WIN32
1993 systems. Affected files are lib/silcutil/silcschedule.[ch],
1994 lib/silcutil/unix/silcunixschedule.c and the
1995 lib/silcutil/win32/silcwin32schedule.c.
1997 * Added new function silc_task_queue_wakeup to wakeup the
1998 scheduler by the specified task queue. Affected file
1999 lib/silcutil/silctask.[ch].
2001 * The silc_socket_host_lookup_start now wakes up the scheduler
2002 after adding the timeout task. Affected file is
2003 lib/silcutil/silcsockconn.c.
2005 * The silc_socket_host_lookup is synchronous now if the threads
2006 support is not compiled in. However, the callback is still
2007 called asyncronously through the scheduler, anyway. Affected
2008 file lib/silcutil/silcsockconn.c.
2010 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2012 * Added new function silc_socket_host_lookup to perform
2013 asynchronous IP and FQDN lookups for the socket connection.
2014 Affected files lib/silcutil/silcsockconn.[ch].
2016 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2018 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2019 that may or may not compile the mutex support in.
2021 Changed the silc_mutex_alloc interface. It allocates the
2022 mutex now to the sent pointer and returns TRUE or FALSE.
2024 Affected file lib/silcutil/silcmutex.h.
2026 * Wrote the SILC Task Queue interface to support multi-threads.
2027 Affected file lib/silcutil/silctask.[ch].
2029 * Wrote the SILC Scheduler to support multi-threads. Affected
2030 file lib/silcutil/silcschedule.c.
2032 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2035 in lib/silcutil/win32/.
2037 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2039 * Defined SILC Mutex API and SILC Thread API and implemented
2040 them for Unix. Affected files are
2041 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2042 lib/silcutil/unix/silcunixmutex.c and
2043 lib/silcutil/unix/silcunixthread.c.
2045 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Fixed the silc_server_remove_clients_by_server's channel
2048 key re-generation. The hash table handling was incorrect
2049 and would not work with many channels. Affected file is
2052 * Fixed some memory leaks around the server code.
2054 * Rewrote the silc_server_get_users_on_channel to support IPv6
2055 based Client ID's. Affected file silcd/server.c.
2057 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2058 specification. However, a separate document must be written
2059 to define the detailed signing procedure and the payload
2060 associated with the flag. Defined the flag to the
2061 lib/silccore/silcchannel.h as well.
2063 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Changed the dynamic tables to static size tables in the
2066 lib/silccrypt/silchmac.c.
2068 * Removed GCC dependencies from the code. A patch by cras.
2070 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * Do not show the error "Error receiving packet bla bla"
2073 in server if it really was not an error (-2 means that reading
2074 is pending). Affected file silcd/server.c.
2076 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * Fixed a possible crash in silc_server_remove_clients_by_server
2079 in silcd/server.c. Fixed there also some memory leaks.
2081 * Fixed the silc_idlist_replace_client_id. It could replace
2082 wrong key in the hash table. Affected file silcd/idlist.c.
2084 * Do not check whether there are global users on the channel
2085 if the channel->global_users is FALSE. Affected functions
2086 silc_server_remove_from_one_channel and
2087 silc_server_remove_from_channels in silcd/server.c. Also,
2088 do not check if the removed client is local as we can be
2089 sure that global client was not removed from the channel
2090 and checking for global users is not needed.
2092 * The silc_server_remove_clients_by_server now re-generates
2093 the channel keys correctly for those channels that had
2094 clients removed from them. Affected file silcd/server.c.
2096 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Found the reason of random crashes in the server. We weren't
2099 ignoring the SIGPIPE signal (which can be sent in write())
2100 and it crashed the server. Affected file silcd/silcd.c.
2102 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2104 * Assure that sock->user_data is not NULL in the function
2105 silc_server_packet_send in silcd/packet_send.c.
2107 * Disconnect the remote connection if it could not be added
2108 to any ID lists in the server. The affected file is
2111 * Check in silc_server_packet_send[_real/dest] that the
2112 socket is not disconnecting and ignore the data if it is.
2113 Affected file silcd/packet_send.c.
2115 * Define inline to __inline on native WIN32 compilation.
2116 Affected file includes/silcwin32.h.
2118 * Added some explicit type casts for inline code since MSVC
2119 require them. Affected files lib/silcutil/silcbuffer.h,
2120 lib/trq/silcdlist.h and lib/trq/silclist.h.
2122 * Print warning in log files from now on if the packet
2123 decryption fails. Affected file silcd/server.c.
2125 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2127 * Changed the `say' client operation's interface to accept
2128 new `type' argument to indicate the type of the message sent
2129 by the library. The application may filter the library's
2130 messages according the type. The affected file is the
2131 lib/silcclient/silcapi.h.
2133 * Added two new functions to lib/silcclient/silcapi.h:
2134 silc_client_del_client and silc_client_del_client_by_id.
2135 Affected file lib/silcclient/idlist.c.
2137 * Moved the clientincludes.h from includes/ to silc/ and
2138 serverincludes.h from includes/ to silcd/.
2140 * The modes for the CMODE and CUMODE are now passed as
2141 uint32 for application with COMMAND_REPLY. The affected
2142 file is lib/silcclient/command_reply.c.
2144 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2146 * /WHOIS without arguments shows client's own information.
2147 Affected file lib/silcclient/command.c.
2149 * Changed PING to not accept any arguments. The specs
2150 says that client can ping only the connected server so
2151 requiring an argument is not needed. Affected file is
2152 lib/silcclient/command.c.
2154 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Fixed a fatal bug in private message sending and reception
2157 encryption and decryption when using private message keys.
2158 The implementation was incorrect and did not follow the
2159 specification. It causd that some of the message were
2160 lost since it did not use the sending and receiving keys
2161 as the protocol suggests. This has been fixed and will cause
2162 incompatibilities with older clients when sending private
2163 message encrypted with private message keys. Affected files
2164 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2165 and various other in Irssi SILC Client.
2167 Added `responder' boolean argument to the functions
2168 silc_client_add_private_message_key[_ske] to indicate when
2169 the key is added as responder or initiator of the key
2172 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * Removed the silc_ske_check_version function and created
2175 a SilcSKECheckVersion callback. Added also a function
2176 silc_ske_set_callbacks that is now used to set all SKE
2177 callbacks. The callback functions are not given to
2178 the SKE functions anymore, but this function is used to
2181 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2183 * Added `silc_version' argument to the silc_client_alloc
2184 to define the version of the application for the library.
2185 The library will use the version string to compare it
2186 against the remote host's (usually a server) version
2187 string. Affected file lib/silcclient/silcapi.h
2189 * Added the KE protocol context to Key Agreement context
2190 in client library so that we can abort the SKE if it
2191 is in process when we get timeout. Affected file is
2192 lib/silcclient/client_keyagr.c.
2194 * Do not resolve the client ID forever if it returns in the
2195 first time that such client does not exist. This was done
2196 for example with private message. Affected file is
2197 lib/silcclient/client_prvmsg.c.
2199 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2201 * Do not add regex.h for WIN32. The affected file
2202 includes/silcincludes.h.
2204 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2205 not work yet 100%. It generates the DLL's automatically
2206 when compiling with --with-win32 under cygwin.
2208 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2210 * lib/contrib/regex.c is not compiled on WIN32.
2212 * Added silc_net_get_socket_opt function to the
2213 lib/silcutil/silcnet.h.
2215 * Added includes/silcwin32.h for WIN32 specific includes
2218 * Do not use ptime structure or any of the posix process
2219 functions on WIN32 in lib/silccrypt/silrng.c.
2221 * Added silc_gettimeofday to provide generic function
2222 for struct timeval on all platforms. Added the function
2223 to lib/silcutil/silcutil.h.
2225 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2228 library as they clearly belong there. As a plus side we
2229 can make the actual socket connection routines platform
2232 Added also new generic function silc_socket_read and
2233 silc_socket_write (that used to be silc_packet_[read/write].
2234 The implementation of these are platform specific.
2236 * Added WIN32 specific routines of silc_socket_[read/write]
2237 to lib/silcutil/win32/silcwin32sockconn.c.
2239 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2241 * Added preliminary support for native WIN32 compilation under
2242 cygwin (using the -mno-cygwin option for GCC) to the
2243 ./configure.in.pre. The --with-win32 now prepares the
2244 compilation for native WIN32.
2246 * Rewrote the SILC Scheduler interface in the file
2247 lib/silcutil/silcschedule.h. The scheduler is now context
2248 based and does not have anymore any global static scheduler.
2249 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2250 and created lib/silcutil/win32 directory for WIN32 based
2253 * Added Unix specific network routines to the
2254 lib/silcutil/unix/silcunixnet.c and the old
2255 lib/silcutil/silcnet.c includes now only generic routines.
2257 Added WIN32 specific network routines to the
2258 lib/silcutil/win32/silcwin32net.c.
2260 * Added Unix specific utility functions from the
2261 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2263 * Added WIN32 SILC Scheduler to the file
2264 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2267 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2269 * Do not handle JOIN notify in the server if the target client
2270 is not registered (idata->registered == FALSE). The affected
2271 file is silcd/packet_receive.c.
2273 * Update the nickrec->founder in event_cumode in the Irssi SILC
2274 client. Affected file irssi/src/silc/core/silc-channels.c.
2276 * Fixed the CUMODE_CHANGE notify handling in the server when
2277 server and router are announcing their clients on channels.
2278 Now the mode changes are saved and notified correctly. The
2279 affected file is /silcd/packet_receive.c.
2281 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2282 They really did not replace the cache entry in the ID Cache.
2283 Now they do that. Affected file silcd/idlist.c.
2285 * Fixed the KICK notify handling in the Irssi SILC client to
2286 update the channel records so that the kicked client does not
2287 appear to be on the channel. The affected file is
2288 irssi/src/silc/core/silc-channels.c.
2290 * Always update the conn->current_channel when executing command
2291 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2293 * Fixed the KILL notify handling in Irssi SILC client to remove
2294 the killed client on all channels.
2296 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2298 * Fixed the silc_parse_command_line to remove extra spaces
2299 from the start and end of the arguments. Affected file is
2300 lib/silcutil/silcutil.c.
2302 * Cancel and free any active protocol in the function
2303 silc_server_close_connection. Affected file silcd/server.c.
2305 * Cancel and free any active protocol in the function
2306 silc_client_close_connction. Affected file is
2307 lib/silcclient/client.c.
2309 * Do not execute the KILL command for clients that are in
2310 history (ie. they are not in the network). Affected file is
2313 * Fixed KILL notify handling, client does not crash anymore.
2314 Affected file irssi/src/silc/core/silc-channels.c.
2316 * Reduced the default packet buffer size from 2048 to 1024 in
2317 lib/silccore/silcpacket.c.
2319 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2320 counter to the SKE context that is incresed when the SKE library
2321 performs async operation outside the library. If the outside
2322 process frees the SKE context and FREED status will be set
2323 and the library will detect after the sync operation that the
2324 libary is freed. The affected files are
2325 lib/silcske/silcske[_status].[ch].
2327 * Resolve the client entry information in the function
2328 silc_client_channel_message to assure that NULL pointer is not
2329 passed as client entry to the application. */
2331 * Fixed the task timeout calculation to assure that there is
2332 never negative timeouts. The affected file is
2333 lib/silcutil/silcschedule.c.
2335 * Fixed the channel user mode notification sending in server.
2336 It was sent point-to-point to the router (or to server by router)
2337 but it needs to be destined to a channel. The routines now
2338 supports sending the channel user mode notifys to the channels
2339 when announcing clients and channels. Affected files are
2340 silcd/server.c and silcd/packet_receive.c.
2342 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2343 It did not actually replace the old channel entry in the cache.
2344 Affected file lib/silcclient/client_notify.c.
2346 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2348 * Fixed a possible crash in silc_packet_send_prepare. It now
2349 assures always that there is enough space in the buffer and
2350 at the tail area of the buffer (for MAC).
2352 Fixed the inbound buffer reallocation in silc_packet_read.
2353 It was old code and did not handle the reallocation correctly.
2356 The affected file is lib/silccore/silcpacket.c.
2358 * Fixed buffer overflow in silc_parse_nickname in the file
2359 lib/silcutil/silcutil.c.
2361 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2363 * make install generates new server keys only if there is not
2366 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2368 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2369 Added check that if the NOREPLY is set then we will not send
2370 the away message. This avoids infinite loop of away messages
2371 if both clients are away. The affected file is
2372 lib/silcclient/client_prvmsg.c.
2374 * Fixed client crash if /NICK was given without arguments.
2375 Affected file lib/silcclient/command.c.
2377 * Server does not send the invite list in INVITE command back
2378 to the client if the list was not altered. Added this notion
2379 to the protocol spec as well. Affected file silcd/command.c.
2381 Fixed possible crash in INVITE command by checking the
2382 value of silc_server_get_client_route command.
2384 * Fixed the INVITE notify type handling. The arguments are now
2385 taken in correct order and client does not crash. The affected
2386 file is irssi/src/silc/core/silc-channels.c.
2388 Removed the "Inviting xxx to channel" message from the
2389 client library away and let the application handle it.
2390 Affected file lib/silcclient/command.c. Added that message
2391 to Irssi SILC client's message formats.
2393 * Fixed CMODE command crash in client. It now checks the
2394 amount of arguments correctly and does not crash. The affected
2395 file is lib/silcclient/command.c.
2397 * Do not create new channel automatically in silc_channels_join
2398 but check whether the channel by that name already exists.
2399 Affected file irssi/silc/core/silc-channels.c.
2401 * Do not send the SERVER_SIGNOFF to router if the disconnected
2402 entity was the router. Affected file silcd/server.c.
2404 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2405 SILC client as it was missing from there.
2407 Added the handling of the KICK notify to the Irssi SILC client
2408 as it was missing. Added "you have been kicked" message to
2409 Irssi SILC client's message modules formats.
2411 Added the handing of the KILL notify to the Irssi SILC client
2412 as it was missing. Added the kill message module formats
2415 The affected file is irssi/src/silc/core/silc-channels.c.
2417 * The router did not save the channel mode the server announced.
2418 Affected file silcd/packet_receive.c.
2420 * Fixed a possible crash in INFO command in server. If the
2421 server did not provide the server info it crashed. Affected
2422 file silcd/command.c.
2424 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2426 * Fixed the GETKEY command in the server to check also the
2427 global list. Otherwise the GETKEY would not work correctly
2428 in normal SILC server. Affected file silcd/command.c.
2430 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * Fixed GETKEY crash, it crashed if the command did not succseed.
2434 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2436 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2437 is now real and not just an macro interface to GMP.
2439 Removed the entire GMP from the source tree and imported new
2440 NSS MPI library instead. Reason for removing GMP is that it is
2441 extremely large and compiles extremely slow. The NSS MPI
2442 is only a few files and compiles in less than 10 seconds.
2443 The speed is also about the same as GMP. The MPI is imported
2444 to lib/silcmath/mpi.
2446 If the system has GMP installed we will still use the GMP.
2447 If it is not then the NSS MPI will be compiled.
2449 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2451 * Merged a long nickname (127 characters long) crash bugfix from
2452 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2454 * Merged a freed memory reference bugfix from Irssi CVS tree.
2455 Affected file irssi/src/core/commands.c.
2457 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2459 * Added the server's public key sving and verification to the
2460 server when performing the SKE. This was missing and the
2461 remote server's (or router's) public key was accepted without
2462 checking whether we have it previously or trust it at all.
2463 Affected file silcd/protocol.c.
2465 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2467 * Check in the silc_server_timeout_remote if protocol is active
2468 and make sure that the protocol's final callback is called so
2469 that all memory if freed. Affected file silcd/server.c.
2471 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * silc_server_whois_send_reply crashed the server if the nickname
2474 was 127 characters long. Affected file silcd/command.c.
2476 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Added sanity check to the silc_server_new_client. If the hostname
2479 is provided inside username then check that the provided hostname
2480 really is the same as the resolved one. If the hostname was not
2481 resolved then check it from the public key. Affected file is
2482 silcd/packet_receive.c.
2484 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2485 if the server disconnected us and the connection is not valid
2486 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2488 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2489 the library to the lib/silcutil/silcutil.[ch].
2491 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Close log file after open. Affected file
2494 lib/silcutil/silclog.c.
2496 * Check whether sock == NULL in silc_client_send_packet and return
2497 if it is. Affected file lib/silcclient/silcclient.c.
2499 * Check rec->entry == NULL in the Irssi SILC Client before
2500 sending the channel message. Affecte file is
2501 irssi/src/silc/core/silc-servers.c.
2503 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2505 * Merged a splitted window bugfix from Irssi CVS tree. The
2506 affected file is irssi/src/fe-text/textbuffer-view.c.
2508 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2509 It did not print nickname.
2511 * Improved the distributions system a bit.
2513 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2516 irssi/src/fe-text/gui-window.c.
2518 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2519 to in-active server. The affected file is
2520 irssi/src/silc/core/client_ops.c.
2522 * Resolve the client in USERS command reply if the entry does
2523 not have username resolved. The affected file is
2524 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2525 command to WHOIS command to really resolve stuff. The USERS
2526 is not used any more in any critical section so WHOIS can
2527 be used even though it might be slower than IDENTIFY.
2529 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2532 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2534 * Changed the protocol API a bit more consistent in the
2535 lib/silccore/silcprotocol.[ch].
2537 * Changed the following headers to ROBODoc format:
2539 lib/silccore/silcpayload.h
2540 lib/silccore/silcprotocol.h
2541 lib/silccore/silcsockconn.h
2543 All core library headers are now formatted.
2545 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2547 * Fixed a bug in Irssi SILC client; do not show that you are
2548 server/router operator if you really are not. Affected file is
2549 irssi/src/silc/core/client_ops.c.
2551 * Renamed silc_command_free_payload to silc_command_payload_free.
2552 Affected file lib/silccore/silccommand.h
2554 * Added silcmath.h to include the prototoypes of various routines
2555 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2558 * Changed the following headers to ROBODoc format:
2560 lib/silccore/silcchannel.h
2561 lib/silccore/silccommand.h
2562 lib/silccore/silcid.h
2563 lib/silccore/silcidcache.h
2564 lib/silccore/silcmode.h
2565 lib/silccore/silcnotify.h
2566 lib/silccore/silcpacket.h
2567 lib/silcmath/silcmath.h
2569 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2571 * Added checking to the server code not to start the server if
2572 ciphers and stuff are not configured properly. Affected files
2573 silcd/serverconfig.[h] and silcd/server.c.
2575 * Changed the layout of the header files of the public interfaces
2576 in the SILC libraries. The new layout supports ROBODoc
2577 documentation tool (and some others) so that it is easy to create
2578 a library reference manual. All the other headers and source
2579 code must still follow the CodingStyle document. Also source
2580 code must not include these ROBODoc stuffs, only the headers.
2581 Furthermore, all public interface headers must now be named
2582 by using `silc' prefix, example: silcapi.h, silccipher.h.
2583 Some files were renamed due to this. All the other headers
2584 must not be used as public interfaces. I will update the
2585 CodingStyle document later. Changed following headers, so far:
2587 lib/silcclient/silcapi.h
2588 lib/silccore/silcauth.h
2589 lib/silccore/silcprivate.h
2590 lib/silccrypt/silcdh.h
2592 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Removed silc_client_packet_send_flush from the client library
2597 as it is not needed. Affected file lib/silcclient/client.[ch].
2599 * Added printing of message of unresolved authentication method
2600 to the Irssi SILC client. Added it to the module formats.
2601 Removed the same message from the client library.
2603 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Added new distribution feature, DISTLABEL. Every distribution
2606 can define own preprocessor label that can be used in the
2607 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2608 file distributions, acconfig.h.pre and prepare.
2610 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Added Makefile.defines_int to include the actual definitions
2613 for Makefile.defines.in. Tested the new distribution system,
2614 created distributions and tested installation.
2616 * Added AWAY message printing to the Irssi SILC client. Added
2617 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2619 * Added SCONNECT command to call the SILC's CONNECT command.
2620 Cannot use CONNECT directly since Irssi uses that internally.
2621 Affected file irssi/src/silc/core/silc-servers.c.
2623 Added ACTION local command. It is same as ME command but takes
2624 the channel as mandatory argument.
2626 Rewrote some of the Irssi's help files to suite for SILC
2629 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Added Makefile.defines[.in] that should for now on be included
2632 in all Makefile.am file in the source tree. That file includes
2633 all common compilation definitions for SILC source tree.
2635 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Minor changes to the ./prepare script to change the package
2638 name according the distribution name to the configure.in.
2640 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2642 * Created new distribution system. Added file `distributions'
2643 that defines all the distributions that can be created out of
2644 the SILC source tree. The ./prepare script now reads that
2645 file to determine how to prepare the distributions. The
2646 first argument to the ./prepare is the name of the distribution
2647 and second is the version of the distribution. If given
2648 without arguments it creates the default (toolkit) distribution
2649 with the default version (defined in ./prepare).
2651 All Makefile.am files that are subject to the distributions
2652 are now named as Makefile.am.pre. These are ./Makefile.am
2653 and lib/Makefile.am. Others may be changed later.
2655 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Added invite list, ban list, some key management and connection
2658 error message printing to module formats in the Irssi SILC client.
2660 * Added new silc_client_set_away_message to set the away message
2661 that is back to the person who sent private message. The
2662 affected file lib/silcclient/silcapi.h and the
2663 lib/silcclient/client_prvmsg.c.
2665 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2667 * Fixed the private message sending in the Irssi SILC client,
2668 added local command KEY to the Irssi SILC client.
2670 Added key management and key agreement message formats to the
2671 irssi/src/fe-common/silc/module-formats.[ch].
2673 Added USERS (alias WHO) printing, server/router operator
2674 indication and LIST command printing to the module formats.
2676 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Fixed channel joining notify handling, cumode notify handling
2679 from Irssi SILC client.
2681 * Added SILC specific module-formats to the Irssi SILC client so
2682 that SILC specific message hilighting, colors etc is possible.
2683 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2685 Added channel mode, channel user mode, actions, notices,
2686 whois and whowas printing to the the module-formats.c.
2688 * Fixed a bug in channel deletion in the server. The channel
2689 is not left to the cache even if the channel founder auth mode
2690 is set when there are no users anymore on the channel. Affected
2691 file silcd/server.c.
2693 * The silc_net_localhost now resolves the entire hostname including
2694 the domain name. Affected file lib/silcutil/silcnet.c.
2696 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2698 * Changed the ask_passphrase client operation to be ascynchronous.
2699 It has now a completion callback and a context that the
2700 application must call after it has got the passphrase from
2701 the user. Affected files lib/silcclient/silcapi.h,
2702 lib/silcclient/protocol.c, lib/silcclient/command.c and
2705 Added SilcAskPassphrase callback that the application calls
2706 to deliver the passphrase to the library.
2708 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2709 The public key verification and especially a certificate
2710 verification is asynchronous procedure.
2712 Added new SILC_SKE_STATUS_PENDING status to indicate the
2713 request is pending and a callback will be called to finalize
2716 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2717 indicate that remote end did not send its public key (or
2718 certificate), even though we require it. Added check for this
2719 condition in the SKE. This was a security bug, now fixed.
2721 Defined new SilcSKEVerifyCbCompletion callback that is called
2722 when the verification process is completed.
2724 The affected files lib/silcske/silcske_status.h and
2725 lib/silcske/silcske.[ch].
2727 * Changed the verify_public_key client operation to be async
2728 as well. Defined SilcVerifyPublicKey callback that is used to
2729 indicate the success of the public key verification process.
2731 Changed the server and client to use the new async client
2734 * Changed the Irssi SILC client's internal scheduler to be called
2735 twice as many times as it used to be. As a result the client
2736 should be a bit faster now. Affected file is
2737 irssi/src/silc/core/silc-core.c.
2739 * Added support to Irssi SILC client of asynchronous public key
2740 verification and passphrase inquiry. Affected file is
2741 irssi/src/silc/core/silc-core.c.
2743 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Do not say "You have left channel %s" in client library.
2746 Moved it to the application. Affected files are
2747 lib/silcclient/command.c and silc/client_ops.c.
2749 * Fixed silc_client_get_clients. Command context was not
2750 duplicated and was freed memory in the callback. Affected
2751 file lib/silcclient/idlist.c.
2753 * Do not say "you are now talking..." on JOIN command in the
2754 client library. The appliation must handle it.
2756 * Do not say ".. changed topic to" in command reply in the
2757 client libary. The application must handle it.
2759 * Fixed TOPIC command sending in the client library.
2761 * Fixed a memory leak in silc_client_command_free in the file
2762 lib/silcclient/command.c.
2764 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Imported a modified version of Irssi client to the source tree.
2767 The Irssi will be used to create a new client called
2768 Irssi SILC. Imported to irssi/.
2770 Added silc_core_init_finish function to the Irssi. Affected
2771 file irssi/configure.in.
2773 A lot changes in the Makefile.ams around the irssi tree.
2775 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2777 * Do not rehash if the new size is same as the old size of the
2778 hash table, in the silc_hash_table_rehash*. The affected file
2779 lib/silcutil/silchashtable.c.
2781 * Replaced hash_table_del_by_context calls from the server
2782 (when channel->user_list and client->channels) to the
2783 hash_table_del as it is sufficient and faster.
2785 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Added silc_hash_table_list, silc_hash_table_get and the
2788 SilcHashTableList structure to provide an alternative way to
2789 traverse the hash table. The affected files are
2790 lib/silcutil/silchashtable.[ch].
2792 * Changed the server's idlist routines to use the hash table
2793 routines to optimize the code.
2795 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * Replaced the client entry's `channel' list and channel entry's
2798 `user_list' list to hash tables for optimized lookup. Changed
2799 the code to use the hash table interface around the code.
2800 Affected file lib/silcd/idlist.[ch].
2802 * Added `auto_rehash' boolean argument to the function
2803 silc_hash_table_alloc to indicate whether the hash table should
2804 auto-rehash when it thinks is appropriate time. It will
2805 increase the hash table size if the there is twice as much
2806 entries in the table than the size of the table, and will
2807 decrease the size if there are twice as less entries than
2808 the size of the table.
2810 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2812 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2814 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2816 * silc_idcache_purge_by_context deletes the entry now by context
2817 as it is supposed to do. Affected file lib/silccore/idcache.c.
2819 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2820 client is not anymore valid (WHOWAS givens the info) and not
2821 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2823 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2825 * Removed the `data' and `data_len' arguments from the ID Cache
2826 interfaces and added `name' argument. ID Cache does not handle
2827 anymore the binary data only a names associated with given ID.
2829 * When hashing a Client ID with silc_hash_id the entire ID is
2830 not hashed anymore, instead only the hash of the Client ID is
2831 hashed. This way we can access the Client ID from the cache
2832 with Client ID but with the hash of the ID (which is a hash of
2833 the nickname) as well without any difference in performance.
2835 Added also silc_idcache_find_by_id_one_ext to do one on one
2836 searching when we have the actual ID. Added also function
2837 silc_hash_client_id_compare. The affected files are
2838 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2840 * When hashing the name associated with a ID it is always done
2841 in lowercase. This way we can access the cache without worrying
2842 about case-sensitivity, even though, for example nicknames are
2845 * Fixed a bug in server with channel message sending. It put
2846 wrong ID type as destination ID. The affected file
2847 silcd/packet_send.c.
2849 * silc_idcache_del_by_context now deletes from all hash tables
2850 by context. Affected file lib/silccore/idcache.c.
2852 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Changed the client library to use the new ID Cache interface.
2855 Changes around the source tree.
2857 * Added silc_hash_table_rehash_ext to rehash with specific
2858 hash function. Affected file lib/silcutil/silchashtable.[ch].
2860 * Added silc_hash_string_compare to compare two strings in the
2861 hash table. Affected file lib/silcutil/silcutil.[ch].
2863 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2865 * Added new function silc_idcache_del_by_context into the
2866 lib/silccore/idcache.[ch].
2868 * Changed the server's ID list routines to use the new ID Cache
2869 interface. Changes around the source tree.
2871 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * Added silc_hash_table_del[_by_context]_ext functions in to the
2874 lib/silcutil/silchashtable.[ch].
2876 Removed silc_hash_table_find_all* routines and added new
2877 silc_hash_table_find_foreach to replace them.
2879 Added silc_hash_table_replace_ext function as extended
2880 replacing function. Separated the simple hash table interface
2881 from the extended hash table interface in the file
2882 lib/silcutil/silchashtable.h.
2884 * Fixed minor bugs and changed it to use some of the new
2885 hash table functions in lib/silccore/idcache.c
2887 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * Added new function silc_hash_table_find_all to return all keys
2890 in the hash table by the specified key. As the hash table is
2891 collision resistant it also makes it possible to have several
2892 duplicate keys in the hash table. This function may be used to
2893 find all of the keys from the hash.
2895 Added user_context arguments to the SilcHashFunction,
2896 SilcHashCompare and SilcHashDestructor to deliver user specified
2899 Added new fuctions silc_hash_table_find[_all]_ext to do
2900 extended lookup with specified hash and compare functions and
2901 specified user contexts.
2903 Added new function silc_hash_table_add_ext to add the key
2904 with specified hash function and user context.
2906 Added new function silc_hash_table_foreach to traverse all
2907 entrys in the hash table. Added SilcHashForeach callback
2910 Added new function silc_hash_table_del_by_context to delete
2911 the entry only if the context associated with the key matches.
2913 Affected files are lib/silcutil/silchashtable.[ch].
2915 * Removed silc_hash_[server/client/channel]_id and added just
2916 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2917 silc_hash_id_compare to compare two ID's using as the hash table
2918 comparison function. Added also silc_hash_data to hash
2919 binary data and silc_hash_data_compare to compare it.
2921 * Removed silc_idlist_find_client_by_hash as it is not needed
2922 anymore. Affected file silcd/idlist.[ch].
2924 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2925 to use internally the SilcHashTable. The new ID Cache is a lot
2926 faster than the old one. Some of the ID Cache interface was also
2927 rewritten and obsolete and stupid functions were removed.
2929 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2931 * Added entry_count field to the SilcHashTable to keep the number
2932 of the entries in the table. Implemented the function
2933 silc_hash_table_rehash. Added new function
2934 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2936 Fixed a minor bug in silc_hash_table_free.
2938 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2939 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2940 into the lib/silcutil/silcutil.[ch].
2942 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Implemented a collision resistant hash table into the
2945 lib/silcutil/silchashtable[ch]. See the header and the source
2946 for the SilcHashTable API.
2948 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2950 * Merged dotconf version 1.0.2 into lib/dotconf.
2952 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2954 * Do not compile anything in lib/silcsim/* if the SIM support
2955 is not enabled. The tree should now compile without problems
2958 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2960 * Compiled the SILC under cygwin. Compiled and tested briefly
2961 without problems. More tests needed. The SIMs didn't compile
2964 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2966 * Fixed possible crash in silc_get_username in the
2967 lib/silcutil/silcutil.c.
2969 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2971 * Fixed a va_arg in silc/client_ops.c.
2973 * Oops, RC5 routines were named AES and caused some problems
2974 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2976 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Added new SilcIDIP structure into the lib/silccore/id.h and
2979 replaced the old `ip' fields from all SILC ID's to that type.
2980 This is a step towards IPv6 support.
2982 The silc_id_get_len takes now the ID as an extra argument.
2983 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2984 both IPv4 and IPv6 based ID's.
2986 The affected files are lib/silccore/id.[ch] and other files
2987 around the tree using these routines.
2989 * Removed the ID length arguments in server from various
2990 silc_server_send_notify_* routines -> they are not needed
2993 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Fixed memory leak in silc_encode_pem_file in the file
2996 lib/silcutil/silcutil.c.
2998 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3000 * Check minor version as well in the SKE. Affected files are
3001 silcd/protocol.c and lib/silcclient/protocol.c.
3003 * Added --identifier option to the server so that an identifier
3004 can be when creating the public key for the server. Affected
3005 file is silcd/silcd.c.
3007 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3008 lib/silccrypt/silcpkcs.c.
3010 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Register default ciphers and stuff when using -C option with
3013 the server. Affected file sildc/silcd.c.
3015 * Put back the servers public key filename format, it is better
3016 than the new one. For now, the client keys are saved with the
3017 new filename format. The affected file silc/client_ops.c.
3019 * Implemented the Cipher API for the rest of the ciphers that
3020 did not implement it or implemented it the wrong way.
3022 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Register default ciphers and stuff when using the -S option
3025 in the client. Affected file silc/silc.c. Same also when
3026 creating new key pair with -C option.
3028 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Fixed the silc_verify_public_key client operation function to
3031 save the public keys differently. The fingerprint is now
3032 used as filename and not the hostname. This way also the
3033 client keys are saved uniquely and not with hostnames. The
3034 affected file is silc/client_ops.c.
3036 * Trimmed the silc_hash_fingerprint function to remove extra
3037 whitespaces from the end of the fingerprint. The affected
3038 file is lib/silccrypt/silchash.c.
3042 * Added silc_cipher_register_default function to register all
3043 default ciphers. It can be used when configuration files
3044 does not exist and the application does not want any specific
3045 ciphers in any specific order.
3047 The SilcDList is now used as silc_cipher_list dynamically
3048 allocated cipher list. Removed the static list all together
3049 and now all ciphers must be allocated to the dynamic list.
3050 The silc_cipher_alloc routine was changed to check only the
3053 All silc_cipher_* routines that used to return int returns
3056 The affected files lib/silccrypt/silccrypt.[ch].
3058 * The same thing was done to silc_hash_* as for silc_cipher_*
3059 routines. Affected files lib/silccrypt/silchash.[ch].
3061 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3062 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3063 Added also silc_pkcs_[un]register[_default] functions.
3064 Removed the data_context from the PKCS API.
3066 * Added silc_hmac_register_default function to register default
3067 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3068 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3069 to unregister all hmacs at once.
3071 * Register the default ciphers, hash functions, PKCSs and HMACs
3072 if client's configuration file does not exist. The affected
3075 * The client did not load the hash functions from the SIM
3076 modules at all. Added support for this. Affected file is
3077 silc/clientconfig.c.
3079 * When decoding public key with silc_pkcs_public_key_decode, check
3080 the supported algorithm only if PKCS are registered. Affected
3081 file lib/silccrypt/silcpkcs.c. The same was done with the
3082 silc_pkcs_private_key_decode.
3084 * Fixed the SILC List routines to keep the list always in order.
3085 It used to change the list's order when traversing the list but
3086 not it preserves the order. Affected file lib/trq/silclist.h.
3088 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * Added the client library to use the SilcSocketConnection's
3091 reference counter (by silc_socket_dup) to prevent the bug that
3092 the socket object may be freed underneath async operation.
3094 * The name resolv library checking fixes in the configure.in.pre.
3097 * Created new version of the protocol drafts for future
3098 development. The -03 drafts are the ones that will be changed
3099 in the trunk now and the -02 will remain as they are.
3101 * Send list of CUMODE notifys to the router when announcing
3102 the channel users to the router. Affected file silcd/server.c.
3103 If the router receiving channel founder CUMODE for a channel
3104 that already has channel founder it will send CUMODE notify
3105 to the sender to remove the channel founder rights from the
3106 announced client. Affected file silcd/packet_receive.c.
3108 * The CUMODE notify may now use Server ID as well as the entity
3109 who changes the mode. Updated protocool specs.
3111 * Updated INSTALL and README files.
3113 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * New web pages in the http://silc.pspt.fi. The pages was
3120 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Implemented the [DenyConnectin] config section in the server.
3123 Added silc_server_config_denied_conn to check whether incoming
3124 connection is denied. Affected file silcd/serverconfig.[ch].
3126 * Do not check the ports when checking the incoming configuration
3127 data if the port is 0, meaning any. Affected file is
3128 silcd/serverconfig.c.
3130 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Fixed buffer overflow in silc_string_compare in the file
3133 lib/silcutil/silcutil.c.
3135 * Fixed double free in silc_server_command_leave in the file
3138 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Fixed the version checking in the server. Affected file is
3143 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Fixed the configuration data fetching when accepting new
3146 connections in the server. Affected file silcd/server.c.
3148 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3150 * Added `sender_entry' argument to the function
3151 silc_server_packet_relay_to_channel so that we can check
3152 whether some destination actually belongs to the same route
3153 the sender belongs (ie, we must not resend the packet to the
3154 sender). Affected file silcd/packet_send.[ch].
3156 * Added `servername' field to the SilcClientEntry in the server
3157 to hold the name of the server where client is from. Affected
3158 file is silcd/idlist.h.
3160 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Moved the channel message encrypting in the router betwen
3163 router connections from silc_server_channel_message to the
3164 silc_server_packet_relay_to_channel since we want to check
3165 whether we have anybody channel before encrypting anything.
3166 Affected files silcd/packet_[receive/send].c.
3168 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3170 * Fixed the [AdminConnection] server config section to support
3171 multiple entries. Affected file silcd/serverconfig.c.
3173 * Added support into the server to check the validity of the
3174 incoming connection before executing any KE or authentication
3177 * The connection configuration is now saved to the KE and
3178 connection auth protocol contexts and not fetched anymore in
3179 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3181 * The local hosts listenning address and port is also resolved
3182 now when starting the server. We want to have the socket object
3183 to include the real address and port for the listener. Added
3184 new function silc_net_check_local_by_sock into the files
3185 lib/silcutil/silcnet.[ch].
3187 * Fixed a broadcast bug in server -> do not broadcast if we
3190 * Fixed a routing bug. Do not route broadcast packets ever.
3191 Broadcast packets must be processed always and not routed since
3192 they may be destined to some other host than yourself and thus
3193 would get routed without no good reason. Affected file is
3196 * Added function silc_server_config_is_primary_route to check
3197 whether primary router connection has been configured (a router
3198 configuration that we are initiating). If there is not, we
3199 will assume that there is only two routers in the SILC network
3200 and we will use the incoming router connection as our primary
3201 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3203 * Changed the order of the broadcasting. Broadcast _after_ the
3204 packet has been processed not before. Affected file is
3207 * Fixed a [ClientConnection] parsing bug. The port was never
3208 parsed correctly thus resulting to port 0. Affected file
3209 silcd/serverconfig.c.
3211 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3212 argument and did not set the broadcast packet flag. Affected
3213 file silcd/packet_send.c. Fixed same bug in the function
3214 silc_server_send_notify as well.
3216 * If we receive NEW_ID packet for our own ID in the server, ignore
3219 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3223 * Removed the nickname from the Private Message Payload.
3224 Updated the code and the protocol specs.
3226 * Updated protocol specs for submitting to the IETF.
3228 * Tweaked the Random Number Generator a bit. Affected file
3229 lib/silccrypt/silcrng.c. Exported a new function
3230 silc_rng_[global]_add_noise which can be used to add more
3233 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Do not parse packets with different timeout when protocol
3236 is active -> may cause problem with rekey. Affected file
3239 * When server receives signoff notify it must not create
3240 new channel key if the client is on any channels since the
3241 sender of the signoff notify will create it.
3243 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3245 * Added printing of error messages during SKE protocol from the
3246 failure packet sent by server during SKE. Affected file
3249 * Removed the client's failure_callback handling with timeout
3250 and handle it immediately when received.
3252 * The SKE library returned wrong type in SUCCESS and FAILURE
3253 packets. They must be 32 bit MSB not 16 bit MSB.
3255 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3257 * Ok, rewrote the logic of the re-key and now it seems to work.
3258 I tested it on high traffic with frequent re-keys without
3259 problems. Added hmac_receive (and renamed hmac to hmac_send)
3260 in SilcClientConnection in lib/silcclient/client.h and
3261 in SilcIDListData in silcd/idlist.h. Also, removed the
3262 SilcPacketParserContext's cipher and hmac fields as they are
3263 not needed anymore and actually caused some problems when
3264 the ciphers and hmac's changed underneath the packet parser.
3266 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * If re-key protocol is active then process the incoming packets
3269 synchronously since we must assure that icoming packets encrypted
3270 with the old key is processed before the new keys is set to
3271 use. This is true other packets than for REKEY packets.
3272 Affected file silcd/server.c. The same was done to client library
3273 as well, affected file lib/silcclient/client.c.
3275 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3277 * Fixed bug in client and server to accept the force send if
3278 the packet is send from silc_[server/client]_packet_process
3279 function. Otherwise the packets are never delivered, oops.
3281 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3283 * Disable force sending of packets when REKEY protocol is active.
3284 We must assure that no packet is sent directly when rekey is
3285 performed. All packets must be sent through packet queue.
3286 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3287 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3288 function is silc_[server/client]_packet_send_real to check
3291 * Replaced the SIM paths from example config files to
3292 /usr/local/modules. Also, make install creates now
3293 /usr/local/silc/logs directory to hold all the SILC server
3296 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Made the configure.in.pre work on Solaris. Patch by salo.
3300 * Made all ciphers compatible with non-x86 machines. Defined
3301 CBC mode macros into lib/silccrypt/ciphers_def.h.
3303 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3305 * Fixed the make install.
3307 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * When MAC computation fails the silc_packet_decrypt returned 0
3310 even though it was supposed to return -1. Fixed this. The
3311 affected file is lib/silccore/silcpacket.c.
3313 * Do not replace the config files in /etc/silc (in make install)
3314 if they already exist. Affected file ./Makefile.am.
3316 * Do not send re-key packets immediately but through packet queue.
3317 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3319 * Changed silc_net_check_host_by_sock to return FALSE if the
3320 IP/DNS could not be resolved. Though, it returns the IP address
3321 now even if it could not resolve it (but returns also FALSE).
3322 Affected file lib/silcutil/silcnet.[ch].
3324 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Added silc_pkcs_decode_identifier to decode the public key's
3327 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3328 Added also silc_pkcs_free_identifier. Added also new context
3329 SilcPublicKeyIdentifier.
3331 * Added -S option to the silc client. It is used to dump the
3332 contents of the specified public key file.
3334 * Changed the PKCS api to return the public key length when
3335 setting the public key.
3337 * Fixed a fatal bug in the public and private key file loading.
3338 Affected file lib/silccrypt/silcpkcs.c.
3340 * Execute the packet parsing for client with zero (0) timeout
3341 if the protocol is active. Affected file silcd/server.c.
3343 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Made the key generation options to the silcd program. Added
3346 -C option, equivalent to client's option.
3348 * Added new [ServerKeys] config section to the server. It
3349 configures the server's public and private key.
3351 * Defined generic Public Key Payload into the protocol
3352 specification to send specific type of public keys and
3355 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3356 public key or certificate.
3358 * Implemented the GETKEY command to the server and to the
3359 client library and on user interface.
3361 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Made preliminary `make install' work.
3365 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Added SilcServerRekey context into silcd/idlist.h.
3369 * Added the PFS support as defined in the specification to the
3370 SKE protocol. Affected files lib/silcske/*.c.
3372 * Added `ske_group' field to the SilcServerRekey context to hold
3373 the number of the SKE group that is used with PFS in re-key.
3374 Affected file silcd/idlist.h.
3376 * Added PFS re-key support to the server. Affected file is
3379 * Added silc_protocol_cancel to cancel execution of the next
3380 state of the protocol. Affected file is
3381 lib/silccore/silcprotocol.[ch].
3383 * Added the re-key support with and without PFS to the client
3384 library. Re-key is performed once in an hour, by default.
3386 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3387 Added silc_client_rekey_callback and silc_client_rekey_final.
3388 Affected files are lib/silcclient/protocol.[ch] and
3389 lib/silcclient/client.[ch].
3391 * Removed the `hmac_key' and `hmac_key_len' fields from the
3392 SilcClientConnection structure; not needed. Affected file is
3393 lib/silcclient/client.h.
3397 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Do not ask whether user wants to use the negotiated private key
3400 for private messages, just use it. Affected file is
3401 silc/local_command.c.
3403 * Added `send_enc_key' and `enc_key_len' fields to the
3404 SilcIDListData structure since they are needed in the re-key
3405 phase. Affected file is silcd/idlist.[ch].
3407 * Implemented the simple re-key protocol into the server.
3408 Affected files silcd/server.c and silcd/protocol.[ch]. The
3409 re-key will be performed once in an hour, by default.
3411 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3412 Added silc_server_rekey, silc_server_rekey_callback and
3413 silc_server_rekey_final.
3415 * Removed Tunneled flag from the protocol. Updated the code
3416 and the specifications.
3418 * Adde `pfs' field to the SilcIDListData to indicate whether
3419 the PFS is to be performed in the re-key. Affected file is
3422 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3425 int64 of at least the xintXX size. If void * is less that 4
3426 bytes uint32 * will be used. Defined bool as boolean.
3428 * Changed _ALL_ unsigned long and unsigned int to uint32,
3429 unsgined short to uint16 in the source tree.
3431 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3432 not handle clients that has entry->data.registered == FALSE.
3433 They are not in the network anymore. Affected file is
3436 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * Implemented the sending of the SERVER_SIGNOFF notify in the
3439 server. Affected file is silcd/server.c.
3441 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3442 Added also silc_notify_payload_encode_args into the
3443 lib/silccore/silcnotify.[ch].
3445 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3446 Affected file silcd/packet_receive.c.
3448 * Implemented the SERVER_SIGNOFF notify handling in the client
3449 library. Affected file lib/silcclient/client_notify.c. Also,
3450 implemnted the printing of the SERVER_SIGNOFF info to the
3451 application. Affected file silc/client_ops.c.
3453 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3454 if the deleting was successful. Affected file silcd/idlist.[ch].
3456 * Added support for public key authentication in the connection
3457 authentication protocol in the client library. Affected file
3458 lib/silcclient/protocol.c.
3460 * Changed the server's silc_idlist_get_clients_by_* interface
3461 to support already allocated array so that new entries may be
3462 added to pre-allocated array. Affected file silcd/idlist.[ch].
3463 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3464 and command replies.
3466 * All command reply functions in the server now calls the
3467 pending command callback even if error occured. This way the
3468 error will be delivered to the client as well. Affected files
3469 silcd/command.c and silcd/command_reply.c.
3471 * Fixed INFO command to return local server's info if no server
3472 was provided. Affected file lib/silcclient/command.c.
3474 * Removed RESTART command for good. Updated the code and the
3477 * Rewrote parts of the task system. It is a bit simpler now.
3478 Removed unsued task priorities. The affected files are
3479 lib/silcutil/silctask.[ch].
3481 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Moved the USERS printing from the library to the application.
3484 Affected files lib/silcclient/command.c and silc/client_ops.c.
3486 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3490 * Added channel key re-key support. The re-key is perfomed
3491 only by the router and is done once in an hour. Added `rekey'
3492 field to the SilcChannelEntry in the server. Affected files
3493 silcd/server.c and silcd/idlist.h.
3495 * Added silc_task_unregister_by_context into the file
3496 lib/silcutil/silctask.[ch].
3498 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Added SILC_UMODE_GONE mode to indicate when the client is not
3501 present in the SILC network. Added also support to the local
3502 command AWAY that will set this mode. Added support of showing
3503 "xxx is gone" in WHOIS command. The USERS command shows the
3504 gone status as well.
3506 * Fixed setting server and router operator privileges in the
3507 server's UMODE command. Affected file silcd/command.c.
3509 * Merged the SKE KE1 and KE2 payloads into one payload. The
3510 new KE payload is equivalent to the old KE2 payload.
3512 Cleaned up the SKE Start Payload parsing. It now uses the
3513 simple buffer unformatting to do the parsing. A lot faster
3516 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3517 to the SKE that is used to indicate whether both of the SKE
3518 parties should perform authentication. By default only the
3519 responder performs authentication. By setting this flag also
3520 the initiator must do authentication. By default it is unset
3521 since in normal SKE case, client to server connection, only
3522 the responder should do authentication. When doing SKE between
3523 two clients both should perform authentication. Updated the
3524 code and the protocol specs.
3526 * A little fix to IDENTIFY command in the server. Search the
3527 client first by hash not nickname. Affected file is
3530 * Fixed the silc_client_close_connection to support closing
3531 the client to client connections wihtout deleting too much
3532 data. Affected file lib/silcclient/client.c.
3534 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3535 are received if protocol used to be active but is not anymore
3536 the application would crash due to NULL pointer dereference.
3537 Affected files silcd/server.c and lib/silcclient/client.c.
3539 * Added `hash' field to the SilcClientConnection to include
3540 the hash function negotiated in the SKE protocol.
3542 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3543 to set the channel founder authentication data. A client can
3544 claim the founder rights later by providing the authentication
3545 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3546 This way the channel founder can regain the channel founder
3547 privileges even it is left the channel. This works only on
3548 local server and the client must be connected to the same
3549 server to be able to regain the founder rights. Updated the
3550 protocol specs accordingly.
3552 Added support to the CMODE command in the client to set the
3553 founder auth data. Read the README to see how to set it.
3555 Added support to the CUMODE command to claim the founder
3556 rights. Read the README to see how to do it.
3558 Added support for the founder authentication to the Channel
3559 Entry in the server. Affected file silcd/idlist.h.
3561 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3562 server's CMODE command. Affected file silcd/command.c.
3564 * Added the following new functions into lib/silccore/silcauth.[ch]:
3565 silc_auth_get_method and silc_auth_get_data.
3567 * The server now saves the remote hosts public key to the
3568 SilcIDListData pointer. Affected file silcd/protocol.c.
3570 * The normal server now does not remove the channel entry from
3571 the cache if the founder authentication data is set. It used
3572 to remove it if the founder was the last one on the channel on
3573 the server and left the channel. The auth data is saved and
3574 if the channel is re-joined later the old entry is used with
3575 the old auth data. Affected files silcd/command_reply.c and
3578 * Removed the `pkcs' field from the SilcIDListData structure
3579 in the server; it is not used. Affected file silcd/idlist.h.
3581 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3583 * Fixed packet processing on slow links. Partial packets were
3584 never re-processed because the incoming data buffer was cleared
3585 by the application. Application must not directly clear the
3586 sock->inbuf, the packet processing routines handle it. Fixed
3587 this in client library and in server.
3589 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Fixed the WHOIS and IDENTIFY send reply function to really
3592 check whether to send list or just one entry. Affected file
3595 * Cleaned up the LEAVE command's channel key distribution. The
3596 affected file silcd/command.c.
3598 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3599 can enforce the channel mode as well. In that case the ID
3600 includes the ID of the server. The code now enforces the
3601 mode change if the router have different mode than the server.
3603 * The notify client operation with CMODE_CHANGE notify can now
3604 return NULL client_entry pointer if the CMODE was not changed
3605 by client. Application must check for this.
3607 * Added <Server ID> argument to INFO command to support server
3608 info fetching by Server ID.
3610 * Added silc_server_announce_get_channel_users to get assembled
3611 packets of channel users of the specified channel. Affected
3612 file silcd/server.[ch].
3614 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3615 was freed underneath the ID Cache.
3617 * Re-announce clients when the server received CHANNEL_CHANGE
3618 notify from the router. Affected file silcd/packet_send.c.
3620 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3623 crashed since it did not handle the fact that there is no cipher
3624 called "3" and didn't check the error condition. Now fixed.
3626 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3627 flag. It can be used to send message requests.
3629 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3631 * Implemented the RESTART command in the client.
3633 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3634 notice type messages. Added notice printing to the user
3637 * The channel keys are not re-generated if the channel's mode
3638 is PRIVKEY, ie private key on the channel exists. Affected
3639 files silcd/server.c and silcd/command.c.
3641 * Fixed a little bug in channel message delivery when channel
3642 private keys are set in the server. Affected file is
3643 silcd/packet_send.c.
3645 * Changed the setting on channel->on_channel = TRUE from the
3646 silc_client_save_channel_key to the JOIN command reply. The
3647 key payload is not received if the private channel key is set.
3648 Affected file lib/silcclient/command_reply.c and the
3649 lib/silcclient/client_channel.c.
3651 * When the CMODE_CHANGE notify is sent and the channel private
3652 key mode is removed the channel key must be re-generated in
3653 other cells as well. Added this support for the router in the
3654 silcd/packet_receive.c.
3656 * Added new local command NOTICE to send notice message on
3657 channel. Affected file silc/local_command.[ch].
3659 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * Added new local command ME to the client. It is used to send
3662 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3663 some action. Affected file silc/local_command.[ch].
3665 * Changed channel_message and private_message client operations
3666 to deliver the message flags to the application. Added also
3667 the `flags' arguments to the silc_client_send_channel_message
3668 and silc_client_send_private_message functions. Affected file
3671 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Redefined the Private Message Payload to support private message
3674 keys and to support the new private message flags. Updated
3675 the protocol specs. Flags makes it possible to have for example
3676 CTCP style messages.
3678 * Added new type SilcPrivateMessagePayload and defined an API
3679 for it in the lib/silcclient/silcprivate.[ch].
3681 * Tested private message private keys successfully. Tested the
3682 private message key set, unset and list commands with the new
3685 * Redefined the Channel Message Payload to include the channel
3686 message flags (equal with private message flags) to support
3687 for example CTCP style messages.
3689 * Defined some of the message (for channel and private message)
3690 flags. Updated the protocol specs and added the flags to the
3691 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3693 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Added SilcKeyAgreementStatus type to the key agreement routines
3696 to indicate the current status and error if one occured.
3697 The status types are defined in the lib/silcclient/silcapi.h.
3699 * Added new local command KEY that is used to set and unset private
3700 keys for channels, set and unset private keys for private messages
3701 with remote clients and to send key agreement requests and
3702 negotiate the key agreement protocol with remote client. The
3703 key agreement is supported only to negotiate private message keys,
3704 it currently cannot be used to negotiate private keys for channels,
3705 as it is not convenient for that purpose.
3707 * Fixed a minor pending callback setting bug in the function
3708 silc_client_get_client_by_id_resolve, now the function works.
3709 Affected file lib/silcclient/idlist.c.
3711 * Added function silc_net_get_local_port to get local bound
3712 port by socket. Added to lib/silcutil/silcnet.[ch].
3714 * Added `sockets' and `sockets_count' fields to the SilcClient
3715 object. They hold the sockets of the listenning sockets in
3716 the client. Listenning sockets may be for example the key
3717 agreement server. Affected file lib/silcclient/client.[ch].
3718 Added functions the silc_client_add_socket and the
3719 silc_client_del_socket. They are exported to the application
3722 * Added ~./silc/clientkeys to support other client's public keys.
3724 * Renamed verify_server_key client operation to verify_public_key
3725 and added one argument to indicate the type of the connection
3726 (server, client etc.).
3728 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3730 * Added silc_server_connection_auth_request to handle the
3731 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3732 silcd/packet_receive.[ch].
3734 * Added silc_server_send_connection_auth_request into the
3735 silcd/packet_send.c to send the connection auth request packet.
3737 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3740 * Fixed the public key authentication in responder side in the
3741 server. The `auth_data' pointer includes the SilcPublicKey
3742 not the path to the public key. Affected file silcd/protocol.c.
3744 * Implemented the public key authentication in the initiator side
3745 in the server. Affected file silcd/protocol.c.
3747 * Removed the [RedirectClient] config section from the server
3748 configuration. Is not needed and I don't want to implement it.
3750 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Cleaned up the CMODE command in the server. It now works
3753 correctly and supports all the modes defined in the protocol.
3754 Affected file is silcd/command.c.
3756 * Added `hmac_name' field to the SilcChannelEntry in the server
3757 to hold the default HMAC of the channel. It can be set when
3758 creating the channel (with JOIN command). Affected files
3761 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3762 type to indicate the change of the current cipher and hmac
3763 on the channel. Client can safely ignore the <cipher> argument
3764 (if it chooses to do so) since the CHANNEL_KEY packet will
3765 force the channel key change anyway. The <hmac> argument is
3766 important since the client is responsible of setting the new
3767 HMAC and the hmac key into use.
3769 * Fixed the CMODE command in the client library as well.
3771 * Tested CMODE command in router environment successfully.
3773 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Show the version of the remote client (or server) when connecting
3776 to the server. It is logged to the log file. Affected file
3777 is silcd/protocol.c.
3779 * Fixed the KILLED notify handling in the client library. The
3780 client must be removed from all channels when receiving the
3783 Also, do not remove the client entry when giving the KILL
3784 command but when the KILLED notify is received.
3786 * Removed silc_idlist_find_client_by_nickname from the server.
3787 Not needed anymore. Affected files silcd/idlist.[ch].
3789 * Implemented the CHANNEL_CHANGE notify type handling to the
3790 server. Affected file silcd/server.c.
3794 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Added silc_server_send_notify_invite to send the INVITE
3797 notify between routers.
3799 * Implemented the INVITE command correctly to the server.
3801 * Implemented the INVITE notify type handling in the server.
3803 * Implemented the INVITE command to the client library and on the
3806 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3808 * Added function silc_server_get_client_resolve to find the
3809 client entry by ID from all ID lists and then resolve it
3810 (using WHOIS) if it cannot be found. Affected file is
3813 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Implemented the BAN command to the client library.
3817 * The JOIN command in the server now checks the invite list
3820 * Changed the silc_command_reply_payload_encode_va and the
3821 silc_command_payload_encode_va to support that if argument is
3822 NULL it ignores and checks the next argument. Affected file
3823 lib/silccore/silccommand.c.
3825 * Added silc_server_send_notify_ban to send the BAN notify
3826 type between routers.
3828 * Chaned the silc_notify_payload_encode to support that if
3829 argument is NULL it ignores and checks the next argument.
3830 Affected file lib/silccore/silcnotify.c.
3832 * Tested ban lists in router environment successfully.
3834 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Implemented BAN command to the server, in silcd/command.[ch].
3838 * Removed the BAN and INVITE_LIST modes from the CMODE command
3841 * Added function silc_string_match to regex match two strings.
3842 Affected files lib/silcutil/silcutil.[ch].
3844 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * Redefined parts of the SilcChannelEntry in the server to support
3847 the new ban and invite lists.
3849 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Redefined the INVITE command. The same command can be used to
3852 invite individuals to the channel but also to manage the invite
3853 list of the channel (to add to and remove from the invite list).
3854 Updated the protocol specs.
3856 * Added new command SILC_COMMAND_BAN that can be used to manage
3857 the ban list of the channel. Updated the protocol specs.
3859 * Removed the channel modes: the SILC_CMODE_BAN and the
3860 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3861 in the CMODE command. The equivalent features are now available
3862 using INVITE and BAN commands. Updated the protocol specs.
3864 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3865 in the network about change in the current ban list. The notify
3866 type is not used by the client.
3868 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3869 support the invite lists.
3871 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3873 * Added new function silc_string_regexify that converts string
3874 including wildcard characters into regex string that can
3875 be used by the GNU regex library. Added into the file
3876 lib/silcutil/silcutil.[ch].
3878 Added silc_string_regex_combine to combine to regex strings
3879 into one so that they can be used as one regex string by
3880 the GNU regex library. Added into the file
3881 lib/silcutil/silcutil.[ch].
3883 Added silc_string_regex_match to match two strings. It returns
3884 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3886 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Imported GNU regex to the soruce tree into lib/contrib.
3889 Fixed some compiler warning from the regex.c.
3891 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Fixed MOTD command in the server to work in router environment.
3895 * Fixed the MOTD command in the client library to support
3896 the server argument in the command.
3898 * Added `nickname_len' argument to the silc_idlist_add_client
3899 in the server, as the `nickname' argument may be binary data
3902 * Added silc_idlist_get_channels to return all channels from
3905 * Implemented LIST command to the server. Affected file is
3908 * Implemented the LIST command to the client library and on the
3911 * Added [<user count>] argument to the LIST command reply.
3912 With private channels the user count is not shown.
3914 * Updated TODO and README.
3916 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * The client entry's data.registered must be TRUE even with
3919 global client entry on global client list. The data.registered
3920 is used to check whether the client is anymore in the network,
3921 for example with WHOWAS command so it must be valid.
3923 * Fixed the WHOWAS command in the server. It now actually works
3924 in router environment. Added function into silcd/command_reply.c
3925 silc_server_command_reply_whowas_save.
3927 * Added silc_idlist_purge function to the silcd/idlist.c
3928 to periodically purge the ID Cache.
3930 * Fixed INFO command in the server. It works now in router
3931 environment. Added <server name> argument to the INFO command
3932 reply. Updated the protocol specs.
3934 * Fixed minor bug in silc_idcache_purge to not purge if the
3935 expire value is zero.
3937 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3938 they were buggy because of the WHOWAS information.
3940 * Fixed local command MSG to handle the async resolving of
3941 the remote client properly. It used to fail the first MSG.
3942 Affected file silc/local_command.c.
3944 * Added `data_len' field to SilcIDCache context.
3946 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Update TODO. Todo in commands in the server.
3950 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3953 used by routers as broadcast packet to inform other routers
3954 about the changed user mode.
3956 Implemented the notify handling in the server. Affected file is
3957 silcd/packet_receive.c. Added the function
3958 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3960 * Added new generic Channel Payload and deprecated the New Channel
3961 Payload. The New Channel Payload is now the generic Channel
3964 * Added new argument `mode' to the silc_server_send_new_channel
3965 as it is required in the Channel Payload now.
3967 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3968 and created a new and real SilChannelPayload to represent the
3969 new generic Channel Payload. Implemented the encode/decode
3970 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3972 * Added silc_server_get_client_channel_list to return the list
3973 of channels the client has joined for WHOIS command reply.
3974 Affected file silcd/server.[ch].
3976 * Implemented the channel list sending in the WHOIS command reply
3977 in server and in the client.
3979 Implemented the channel list displaying on the user interface
3980 as well. Affected file silc/client_ops.c.
3982 * Added silc_channel_payload_parse_list to parse list of Channel
3983 Payloads. It returns SilcDList list of SilcChannelPayloads.
3984 Client for example can use this function to parse the list of
3985 channels it receives in the WHOIS command reply. The caller
3986 must free the list by calling silc_channel_payload_list_free.
3987 Affected files lib/silccore/silcchannel.[ch].
3989 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Added one new argument <user mode> to the WHOIS command reply
3992 to return the mode of the user in SILC. Updated the protocol
3995 Implemented it to the server and client.
3997 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3999 * Fixed the mode printing on the user interface on joining.
4000 Affected file silc/client_ops.c.
4002 * Implemented the UMODE command and user modes in general to the
4003 client library and to the user interface.
4005 * Implemented the UMODE command to the server.
4007 * The server now sends UNKNOWN_COMMAND error status if client sends
4008 unknown command. Affected file silcd/command.c.
4010 * All server commands now handle the command identifier the right
4011 way when sending the command reply to the client. The client can
4012 use to identify the command replies with the identifier.
4014 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Added silc_server_get_client_route to resolve the route to
4017 the client indicated by the client ID. Affected file is
4020 * Added silc_server_relay_packet as general function to relay
4021 packet to arbitrary destination. This deprecates functions
4022 like _send_private_message_key, _relay_notify etc. Affected
4023 file is silcd/packet_send.[ch].
4025 Removed silc_server_send_key_agreement,
4026 silc_server_send_private_message_key and
4027 silc_server_packet_relay_notify functions from the file
4028 silcd/packet_send.[ch].
4032 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4033 server. Affected file silcd/packet_receive.[ch].
4035 * Implemented the KILL command to the client. Implemented the
4036 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4037 Affected files lib/silcclient/command[_reply].c and
4038 lib/silcclient/client_notify.c. Implemented the KILL notify
4039 printing in the user inteface.
4041 * Fixed a lot silc_parse_nick memory leaks from the client
4042 library in the file lib/silcclient/command.c.
4044 * Changed the silc_server_send_notify_on_channels's `sender'
4045 argument from SilcSocketConnection to SilcClientEntry to
4046 check the sender as entry and not as connection object and not
4047 to send to the client provided as argument. The affected file
4048 is silcd/packet_send.[ch].
4050 * The notify packets that are destined directly to the client used
4051 to not to be processed by the server. Now changed that and the
4052 server processes all notify packets. After relaying the packet
4053 to the client the notify packet is processed in the server.
4055 * The silc_server_free_client_data now checks whether there is
4056 pending outgoing traffic for the client and purges the data to
4057 the network before removing the client entry.
4059 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4062 an client is killed from the SILC Network. Updated the protocol
4065 Added new function silc_server_send_notify_killed to the
4066 silcd/packet_send.[ch].
4068 * Added function silc_server_packet_relay_notify to relay notify
4069 packets that are destined directly to a client. In this case
4070 the server does not process the notify packets but merely relays
4071 it to the client. Affected file silcd/packet_send.[ch].
4073 Added also silc_server_packet_process_relay_notify to check
4074 whereto relay the notify. Affected file is
4075 silcd/packet_receive.[ch].
4077 * Implemented the KILL command to the server.
4081 * Added the backup schema desgined last fall to the protocol
4082 specs for everyone to see. The specification is in the
4083 *-spec-xx.txt draft and the packet type definitions for the
4084 backup routers is in *-pp-xx.txt draft. Thusly, added also
4085 new packet type SILC_PACKET_CELL_ROUTERS.
4087 * A big security problem in the implementation discovered. The
4088 signoff of an client did not cause new channel key generation
4089 which it of course should've done. The channel keys must be
4090 always re-generated when client leaves (or signoffs) the channel.
4091 The silc_server_remove_from_channels funtion now handles
4092 the channel key re-generation.
4094 * Added `sender' argument to the silc_server_send_notify_on_channels
4095 to not to send the client provided as argument. Affected file
4096 silcd/packet_send.[ch].
4098 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4100 * Implemented OPER and SILCOPER commands into the server and
4103 * Added silc_auth_verify and silc_auth_verify_data to verify
4104 the authentication directly from the authentication payload.
4105 It supports verifying both passphrase and public key based
4106 authentication. Affected file lib/silccore/silcauth.[ch].
4108 * Added `hash' field to the SilcIDListData structure. It is the
4109 hash negotiated in the SKE protocol. Affected file is
4112 * Slight redesigning of the SilcAuthPayload handling routines.
4113 Do not send SilcPKCS but SilcPublicKey as argument.
4115 * Implemented the public key authentication support to the
4116 serverconfig. The public key is loaded from the provided path
4117 and saved as authentication data to void * pointer. Thus,
4118 changed the unsigned char *auth_data to void *auth_data;
4120 * Fixed SHUTDOWN command to send the reply before the server
4121 is shutdown. :) Affected file silcd/command.c.
4123 * Fixed fatal bug in CONNECT command. The hostname was invalid
4124 memory and server crashed. Affected file silcd/command.c.
4126 * Fixed fatal bug in CLOSE command. The server_entry became
4127 invalid but was referenced later in the command. Affected file
4130 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Fixed fatal bug in failure packet handling. Server ignored
4133 the failure and thus crashed when it came.
4137 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4139 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4140 that the command may be executed only once in (about) 2 seconds.
4141 The old SILC_CF_LAG flag is same but allows command bursts up
4142 to five before limiting.
4144 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4145 server code. Various commands now includes the CF_LAG_STRICT
4146 flag to disallow any kind of miss-use of the command.
4148 * Fixed the silc_buffer_unformat to not to allocate any data
4149 if the length of the data is zero. It used to allocate the
4150 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4152 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4154 * Changed the format of AdminConnection configuration section
4155 in the server. Added username of the admin to the format.
4156 Affected files silcd/serverconfig.[ch].
4158 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4159 to return admin configuration data by host, username and/or
4162 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Implemented WHOWAS command to the server. Added the functions:
4166 silc_server_command_whowas_parse,
4167 silc_server_command_whowas_send_reply,
4168 silc_server_command_whowas_from_client and
4169 silc_server_command_whowas_from_server
4171 * Added <Client ID> argument to the WHOWAS command reply. Updated
4172 the protocol specs accordingly.
4174 * Implemented WHOWAS command and command_reply to the client
4177 Implemented the WHOWAS printing on the user interface.
4179 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Added new argument to the WHOWAS command reply, the real name.
4182 It is an optional argument. Updated the protocol specs.
4184 * Added SilcIDCacheDestructor callback that is registered when
4185 the SilcIDCache is allocated. The callback is called when
4186 an cache entry in the ID Cache expires, or is purged from the
4187 cache. Added into lib/silccore/idcache.[ch].
4189 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4190 to destruct the client entries when the cache entry expires.
4191 Other ID Cache's in server and in the client library ignores
4194 * If the ID Cache entry's `expire' field is zero then the entry
4195 never expires. Added boolean `expire' argument to the
4196 silc_idcache_add function in the lib/silccore/idcache.[ch].
4197 If it is TRUE the default expiry value is used.
4199 * Added silc_server_free_client_data_timeout that is registered
4200 when client disconnects. By default for 5 minutes we preserve
4201 the client entry for history - for WHOWAS command.
4203 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Added support to the server to enforce that commands are not
4206 executed more than once in 2 seconds. If server receives
4207 commands from client more frequently, timeout is registered
4208 to process the commands. Affected file silcd/command.c.
4209 Added new function silc_server_command_process_timeout.
4211 * Changed NICK_NOTIFY handling in client library to check that
4212 if the client's nickname was changed, so there is no need to
4213 resolve anything from the server.
4215 * Removed error printing from the WHOIS and IDENTIFY commands.
4216 If error occurs then it is ignored silently in the client library.
4217 The application, however, may map the received error to
4218 human readable error string. The application currently maps
4219 the NO_SUCH_NICKNAME error to string.
4221 * Made the command status message public to the application. Moved
4222 them from lib/silcclient/command_reply.c to
4223 lib/silcclient/command_reply.h. The application can map the
4224 received command status to the string with the
4225 silc_client_command_status_message function.
4227 * Added check to the server to check that client's ID is same
4228 as the Source ID in the packet the client sent. They must
4231 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4233 * Added dist-bzip hook to the Makefile.am to make bzip2
4234 compressed distributions.
4236 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Server now enforces the maximum length for the nickname and
4239 the channel as protocol specification dictates. 128 bytes for
4240 nickname and 256 bytes for channel name.
4242 * Moved the WHOIS printing to the application. The client libary
4243 does not print out the WHOIS information anymore, the application
4244 must do it. Renamed silc_client_command_reply_whois_print to
4245 the silc_client_command_reply_whois_save.
4247 The client's idle time is also sent to the application now, and
4248 the idle is shown on screen.
4250 * Added silc_client_command_reply_identify_save to save the
4251 received IDENTIFY entries.
4253 * Do not check for channel private keys in message sending and
4254 reception if the channel does not have the PRIVKEY mode set.
4255 Affected file lib/silclient/client_channel.c.
4257 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4260 just surfaced after chaning the JOIN procedure.
4262 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4264 * Added silc_client_get_clients_by_list to get client entries
4265 from Client ID list, that is returned for example by JOIN
4266 and USERS command replies. The application should use this
4267 function for example when JOIN command reply is received to
4268 resolve the clients already on the channel (library does not
4269 do that anymore as USERS command reply is not used in the JOIN
4270 procedure anymore). Affected files lib/silcclient/silcapi.h and
4271 lib/silcclient/idlist.c.
4273 * JOIN command reply and USERS command reply returns now SilcBuffer
4274 pointers instead of unsigned char pointers when returning
4275 the client list and mode list.
4277 * Added <Client ID> argument to the JOIN command reply, mainly
4278 for the server to identify for which client the command was
4279 originally sent. Updated protocol specs accordingly.
4281 * Added SilcDlist private_key pointer to the SilcChannelEntry
4282 in the client to support the channel private keys. Affected
4283 file is lib/silcclient/idlist.h.
4285 * Added SilcChannelPrivateKey argument to the function
4286 silc_client_send_channel_message so that application can choose
4287 to use specific private ke if it wants to. If it is not provided,
4288 the normal channel key is used, unless private keys are set.
4289 In this case the first (key that was added first) is used
4290 as the encryption key.
4292 * Implemented the support for channel private key handling.
4293 Implemented the following functions:
4295 silc_client_add_channel_private_key,
4296 silc_client_del_channel_private_keys,
4297 silc_client_del_channel_private_key,
4298 silc_client_list_channel_private_keys and
4299 silc_client_free_channel_private_keys
4301 Affected file lib/silcclient/client_channel.c.
4303 * Added the support for the private keys in the channel message
4304 sending and encryption and in the message reception and
4305 decryption. Affected funtions are
4306 silc_client_send_channel_message and silc_client_channel_message.
4308 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Added SKE's key verify callback to the client library's
4311 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4313 * Removed the statement that server (or router) must send USERS
4314 command reply when joining to the channel so that the client
4315 knows who are on the channel. Instead, the client list and
4316 client's mode list is now sent in the JOIN command reply to the
4317 client who joined channel. This is better solution.
4319 * Added function silc_server_get_users_on_channel and function
4320 silc_server_save_users_on_channel to the silcd/server.[ch].
4322 * Removed function silc_server_command_send_users from the
4325 * Do not show topic on the client library anymore. The topic is
4326 sent in the command reply notify to the application and the
4327 application must show the topic now.
4329 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Added client searching by nickname hash into the IDENTIFY and
4332 WHOIS commands in the server as they were clearly missing from
4333 them. Affected file is silcd/command.c.
4335 * Fixed a bug in private message receiving in the client library.
4336 The remote ID was freed and it wasn't supposed, now it is
4339 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Minor fix to the channel payload; allocate the data area, as it
4342 needs to be of specific length.
4344 * If the key agreement port is zero then the operating
4345 system will define the bound port. Affected files are
4346 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4348 * Added new function silc_channel_payload_decrypt into the file
4349 lib/silccore/silcchannel.[ch].
4351 * Moved the channel message etc, check from silc_packet_decrypt
4352 to applications. The library calls now a generic
4353 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4354 when the packet is either normal or special. This was done to
4355 allow more wide range of checking that was not allowed when
4356 the code was in library. Now applications can do virtually any
4357 checks to the packet and return to the library the decision how
4358 the packet should be processed. Affected files are
4359 lib/silccore/silcpacket.[ch].
4361 Added silc_server_packet_decrypt_check to the server and
4362 silc_client_packet_decrypt_check to the client library.
4364 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4365 to send with specified source and destination information.
4367 * Channel message delivery between routers was broken after the
4368 channel key distribution was fixed earlier. The channel key
4369 was used be to distributed to other routers as well which is not
4370 allowed by the protocol. Now this is fixed and channel keys
4371 really are cell specific and the channel message delivery between
4372 routers comply with the protocol specification.
4374 * Fixed various commands in server to check also the global list
4375 for the channel entry and not just the local list. The affected
4376 file silcd/command.c.
4378 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Added assert()s to buffer formatting and unformatting routines
4381 to assert (if --enable-debug) when error occurs. Affected
4382 file: lib/silcutil/silcbuffmt.c.
4384 * Changed to auto-reconnect to check whether the remote host is
4385 router and register the re-connect timeout if it is. It used
4386 to check that whether we are normal server, but router must do
4387 auto-reconnect with another router as well. Affected file
4390 * Removed the [<key len>] option from CMODE command as the cipher
4391 name decides the key length, nowadays. See the defined ciphers
4392 from the protocol specification.
4394 * Added [<hmac>] option to the CMODE command to define the HMAC
4395 for the channel. Added SILC_CMODE_HMAC channel mode.
4397 * Added [<hmac>] option for the JOIN command so that user can
4398 select which HMAC is used to compute the MACs of the channel
4401 * Added Hmac field to the Channel Message Payload. The integrity
4402 of plaintext channel messages are now protected by computing
4403 MAC of the message and attaching the MAC to the payload. The
4404 MAC is encrypted. Now, it is clear that this causes some
4405 overhead to the size of the packet but rationale for this is that
4406 now the receiver can verify whether the channel message decrypted
4407 correctly and also when private keys are set for the channel the
4408 receiver can decrypt the packet with several keys and check from
4409 the MAC which key decrypted the message correctly.
4411 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4412 lib/silccrypt/silccipher.[ch].
4414 * Added silc_hash_len to return the digest length into the
4415 lib/silcrypt/silchash.[ch].
4417 * Rewrote parts of Silc Channel Payload interface in the
4418 lib/silccore/silcchannel.[ch]. The encode function now also
4419 encrypts the packet and parse function decrypts it.
4421 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Fixed a minor formatting bug in the SKE's key material processing.
4424 It actually might have processed the keys wrong way resulting
4427 * Redefined the mandatory HMAC algorithms and added new algorithms.
4428 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4429 and hmac-md5 truncated to 96 bits. The mandatory is now
4430 hmac-sha1-96. Rest are optional (including the one that used
4431 to be mandatory). Rationale for this is that the truncated HMAC
4432 length is sufficient from security point of view and can actually
4433 make the attack against the HMAC harder. Also, the truncated
4434 HMAC causes less overhead to the packets. See the RFC2104 for
4437 * Added new [hmac] configuration section. The SKE used to use
4438 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4439 is of course wrong. The official names that must be proposed in
4440 the SKE are the ones defined in the protocol specification
4441 (hmac-sha1-96 for example). The user can configure any hmac
4442 using any hash function configured in the [hash] section. At
4443 least, the mandatory must be configured.
4445 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4447 * Added HMAC list to the SKE proposal list. It has now both
4448 hash algorithm list and HMAC list. This makes the protocol
4449 incompatible with previous versions. The SKE now seems to work
4450 the way it is supposed to work, for the first time actually.
4452 * Defined plain Hash algorithms to the protocol specification.
4455 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Implemented support for key agreement packets into the server.
4458 Added functions silc_server_key_agreement and
4459 silc_server_send_key_agreement. Other than these functions,
4460 server has nothing to do with this packet.
4462 * Added support for private message key packets into the server.
4463 Added functions silc_server_private_message_key and
4464 silc_server_send_private_message_key.
4468 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4469 called in the protocol's final callback instead in the END
4470 protocol state. This makes a little more sense and in the same
4471 time in client we can use the same protocol routines for normal
4472 key exchange and to key agreement packet handling as well.
4474 * Added to both client's and server's KE protocol context the
4475 SilcSKEKeyMaterial pointer to save the key material. We will
4476 bring the key material to the protocol's final callback by doing
4477 this. The final callback must free the key material.
4479 * Added SKE's packet_send callback into client's KE protocol
4480 context so that the caller can choose what packet sending function
4481 is used. This way we can use different packet sending when
4482 doing normal SKE when doing key agreement packet handling (in
4483 the key agreement packet handling we do not want to encrypt
4486 * Implemented the responder side of the key agreement routines
4487 in the client. The client can now bind to specified port and
4488 accept incoming key negotiation. The key material is passed
4489 to the application after the protocol is over.
4491 * Implemented the processing of incoming Key Agreement packet
4492 in the client. Added function silc_client_key_agreement to
4495 * Implemented the intiator side of the key agreement routines
4496 in the client. The client can now initiate key agreement with
4497 another remote client. The key material is passed to the
4498 application after the protocol is over.
4500 * Created client_keyagr.c to include all the key agreement
4503 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4504 SILC_TASK_CALLBACK except that it is not static.
4506 * Created client_notify.c and moved the Notify packet handling
4507 from the client.[ch] into that file.
4509 * Created client_prvmsg.c and moved all private message and
4510 private message key routines from the client.[ch] into that file.
4512 * Create client_channel.c and moved all channel message and
4513 channel private key routines from the client.[ch] into that file.
4515 * Changed silc_client_get_client_by_id_resolve to resolve with
4516 WHOIS command instead of IDENTIFY command, in the file
4517 lib/silclient/idlist.c.
4519 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Implemented the SKE's responder side to the Client library.
4523 * When FAILURE is received to the protocol do not trust it
4524 blindly. Register a timeout to wait whether the remote closes
4525 the connection as it should do it, only after that process the
4526 actual failure. This was changed to both client and server.
4528 * Added client_internal.h to include some of the structures
4529 there instead of client.h in lib/silcclient/.
4531 * Added function silc_task_unregister_by_callback to unregister
4532 timeouts by the callback function.
4534 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Some "Incomplete WHOIS info" errors has been appearing on the
4537 log files. Took away the entry->userinfo check from WHOIS
4538 reply sending. The entry->userinfo is now " " if client did not
4539 provide one. I thought this was fixed earlier but something
4540 is wrong still. Let's see if the error still appears.
4542 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Fixed a minor bug in the login when the channel key is
4545 re-generated in the server. It used to generate the key in
4546 wrong order and thus caused problems in the channel traffic.
4548 * Fixed a minor bug in channel key distsribution after
4549 KICK command. The key was not sent to the router even though
4552 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Added silc_ske_process_key_material_data as generic routine
4555 to process any key material as the SILC protocol dictates. The
4556 function is used by the actual SKE library but can be used by
4557 applications as well. This relates to the private message keys
4558 and the channel private keys since they must be processed the
4559 same way the normal SILC session keys. The protocol dictates
4560 this. Affected files: lib/silcske/silcske.[ch].
4562 Added also silc_ske_free_key_material to free the
4563 SilcSKEKeyMaterial structure.
4565 * Defined silc_cipher_set_key function to set the key for
4566 cipher without using the object's method function. The affected
4567 files: lib/silccrypt/silccipher.[ch].
4569 * Implemented silc silc_client_add_private_message_key,
4570 silc_client_add_private_message_key_ske,
4571 silc_client_del_private_message_key,
4572 silc_client_list_private_message_keys and
4573 silc_client_free_private_message_keys functions in the
4576 Added functions silc_client_send_private_message_key to send
4577 the Private Message Key payload and silc_client_private_message_key
4578 to handle incoming Private Message Key payload.
4580 * Added Cipher field to the Private Message Key payload to set
4581 the cipher to be used. If ignored, the default cipher defined
4582 in the SILC protocol (aes-256-cbc) is used.
4584 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Removed lib/silcclient/ops.h file.
4588 Redefined parts of the SILC Client Library API. Created new
4589 file silcapi.h that deprecates the ops.h file and defines the
4590 published Client Library API. Defined also private message key
4591 API and channel private key API into the file.
4593 This is the file that the application must include from the
4594 SILC Client Library. Other files need not be included by
4595 the application anymore.
4597 * Added new key_agreement client operation callback and also
4598 defined the Key Agreement library API for the application.
4600 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4603 is used by clients to request key negotiation between another
4604 client in the SILC network. If the negotiation is started it
4605 is performed using the SKE protocol. The result of the
4606 negotiation, the secret key material, can be used for example
4607 as private message key.
4609 Implemented the Key Agreement payload into the files
4610 lib/silccore/silauth.[ch].
4612 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Redefined ciphers for the SILC protocol. Added some new ciphers
4615 and defined the key lengths for the algorithms. Changed the
4616 code accordingly. The default key length is now 256 bits.
4618 * Fixed SKE key distribution function silc_ske_process_key_material
4619 when the key length is more than 128 bits. The default key
4620 length in SILC is now 256 bits.
4622 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4623 to indicate unsupported algorithm.
4625 * Renamed rijndael.c to aes.c and all functions as well.
4627 * Fixed a long standing channel key setting bug in client library.
4628 Weird that it has never surfaced before.
4630 * Fixed bug in channel deletion. If the entire channel is removed
4631 then it must also delete the references of the channel entry
4632 from the client's channel list as the client's channel entry and
4633 the channel's client entry share same memory.
4635 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Implemented CONNECT and SHUTDOWN commands in the client.
4639 * Implemented CLOSE command to the client.
4641 * Added the function silc_idlist_find_server_by_name into the
4642 files silcd/idlist.[ch].
4644 Added the function silc_idlist_find_server_by_conn into the
4645 files silcd/idlist.[ch].
4647 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * DIE command was renamed to SHUTDOWN. Updated the both code
4652 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4653 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4655 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4658 * Added function silc_server_create_connection function to create
4659 connection to remote router. My server implementation actually
4660 does not allow router to connect to normal server (it expects
4661 that normal server always initiates the connection to the router)
4662 so the CONNECT command is only good for connecting to another
4665 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4668 or some other client was kicked from the channel.
4670 Implemented the handling of the notify type to both client
4673 Implemented silc_server_send_notify_kicked to send the KICKED
4674 notify. It is used to send it to the server's primary router.
4676 * Implemented the KICK command into server and client.
4678 * Added `query' argument to the silc_idlist_get_client function
4679 to indicate whether to query the client from server or not if
4682 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4683 to indicate that the client is not channel founder.
4687 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Removed the rng context from SilcPacketContext structure and
4690 changed that the packet routine uses the Global RNG API.
4692 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * Added support for quit message that client can "leave" on the
4695 channel when it quits the SILC. It is ditributed inside the
4696 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4698 Added silc_server_free_client_data that will take the
4699 signoff message as argument.
4701 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4703 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Updated parts of the protocol specification to keep it up
4708 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4711 payloads in one packet.
4713 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4714 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4715 use now the new List flag.
4717 * Also deprecated the following packet types: REPLACE_ID,
4718 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4720 * Added list support for Notify packet in server.
4722 * Added silc_server_send_notify_channel_change to send the
4723 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4724 the silc_server_send_replace_id.
4726 * Added silc_server_send_notify_nick_change to send the
4727 NICK_CHANGE notify type. Deprecates the function
4728 silc_server_send_replace_id.
4730 * Added silc_server_send_notify_join to send the JOIN notify type.
4731 Deprecates the function silc_server_send_new_channel_user.
4733 * Added silc_server_send_notify_leave to send LEAVE notify type.
4734 Deprecates the function silc_server_send_remove_channel_user.
4736 * Added silc_server_send_notify_cmode and
4737 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4738 types. Deprecates the silc_server_send_set_mode function.
4740 * Added SERVER_SIGNOFF notify type to indicate that server has
4741 quit. This means that all clients on the channel from that
4742 server will drop. This can be also used when netsplit happens.
4744 Deprecated REMOVE_ID packet type since it is not needed anymore
4747 Added silc_server_send_notify_server_signoff to send the
4748 SERVER_SIGNOFF notify type. Deprecates the function
4749 silc_server_send_remove_id.
4751 Added also silc_server_send_notify_signoff to send the
4752 SIGNOFF notify type.
4754 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4755 SILC protocol from this day on. Changed the protocol
4756 specification as well.
4758 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4759 notify type. It is used between routers to notify about
4760 topic changes on a channel.
4762 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4765 * Partly updated the protocol specification to comply with the
4766 changes now made. It is still though a bit outdated.
4768 * The JOIN notify type now takes one extra argument <Channel ID>.
4769 The packet used to be destined to the channel but now the
4770 JOIN type may be sent as list thus it is impossible to
4771 destine it to any specific channel. By adding this argument
4772 it is again possible.
4774 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Added CREDITS file. The CHANGES and CREDITS file will appear
4777 in the distribution as well.
4779 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4782 types in the server's silcd/packet_receive.c.
4784 * Implemented CMODE and CUMODE to work in router environment.
4786 * Fixed minor encoding and decoding buglet from the
4787 lib/silccore/silcmode.c.
4789 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4792 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4794 * Changed all SilcConfigServer* and silc_config_server* to
4795 SilcServerConfig* and silc_server_config*, respectively.
4798 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Associated the ID (client or server ID) to the Authentication
4801 Payload to avoid any possibility of forging. Updated the
4802 protocol specification and the code accordingly.
4804 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * The RSA key length is now save to the RsaKey context in the
4807 key generation process in lib/silccrypt/rsa.c. The key length
4808 is now used to figure out the maximum size of the block allowed
4809 to be encrypted/signed.
4811 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4812 is equivalent to the silc_mp_mp2bin but does not allocate any
4815 * Changed silc_mp_mp2bin API to take length argument. If it is
4816 non-zero then the buffer is allocated that large. If zero, then
4817 the size is approximated using silc_mp_sizeinbase, which however
4820 * Created Global RNG API which is global RNG that application can
4821 initialize. After initializing, any routine anywhere in the
4822 code (including library) can use RNG without allocating a new
4823 RNG object. This was done to allow this sort of use of the
4824 RNG in code that has no chance to allocate RNG object. All
4825 applications currently allocate this and many routines in the
4826 library use this. Affected file lib/silccrypt/silcrng.[ch].
4828 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4829 it to use the Global RNG API.
4831 * Defined Authentication Payload into protocol specification that
4832 is used during SILC session to authenticate entities. It is
4833 used for example by client to authenticate itself to the server
4834 to obtain server operator privileges.
4836 Implemented this payload into the lib/silccore/silcauth.[ch].
4837 Implemented also routines for public key based authentication
4838 as the new protocol specification dictates.
4840 Moved definitions of different authentication methods from
4841 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4843 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4844 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4845 silc_pkcs_verify_with_hash functions into the file
4846 lib/silccrypt/silcpkcs.[ch].
4848 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * The client entry's userinfo pointer must be always valid.
4851 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4852 will fail since it requires the userinfo. Now, the userinfo
4853 is allocated as "" if actual userinfo does not exist. Actually,
4854 it must exist and it is totally Ok to drop client connections
4855 that does not announce the userinfo. However, we will make
4856 this workaround for now.
4858 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4859 to return the remote port by socket.
4861 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4864 SILC_SERVER_PENDING_EXEC and added an new macro
4865 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4866 data or when error occurs while processing the pending command.
4868 Added new argument `destructor' into silc_server_command_pending
4869 and to the SilcServerCommandPending object. This destructor is
4870 now called after calling the pending callback or if error occurs
4871 immediately. If error occurs the actual pending callback won't
4872 be called at all - only the destructor. The destructor may be
4873 NULL if destructor is not needed.
4875 All this applies for client library code as well. Similar
4876 changes were made there as well for the pending commands.
4878 In the client, the application must now allocate the
4879 SilcClientCommandContext with the silc_client_command_alloc
4882 * Added reference counter to the SilcServerCommandContext. Added
4883 function silc_server_command_alloc and silc_server_command_dup
4886 Same type of functions added to the client library for the same
4889 * Removed the cmd_ident from IDListData away since it is now
4890 global for all connections. It is the command identifier used
4891 in command sending and with pending commands. The affected file
4894 * Added reference counter to the SilcSocketConnection objecet to
4895 indicate the usage count of the object. The object won't be
4896 freed untill the reference counter hits zero. Currently only
4897 server uses this, and client ignores it. The client must be
4898 set to use this too later. The affected files are
4899 lib/silccore/silcsockconn.[ch]. Added also the function
4900 silc_socket_dup to increase the reference counter.
4902 This was mainly added because it is possible that the socket
4903 is removed underneath of pending command or other async
4904 operation. Now it won't be free'd and proper DISCONNECTING
4905 flags, etc. can be set to avoid sending data to connection that
4906 is not valid anymore.
4908 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4909 the connection. After that it sets SILC_SET_DISCONNECTED.
4910 It is, however, possible that the socket data is not still freed.
4911 The silc_server_packet_process now checks that data is not
4912 read or written to connection that is DISCONNECTED. The socket
4913 get's freed when the reference counter hits zero.
4915 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Changed the client operation API: channel_message operation's
4918 `sender' is now the client entry of the sender, not the nickname
4919 and the `channel' is the channel entry, not the channel name.
4921 In the private_message operation the `sender' is now also the
4922 client entry of the sender not the nickname.
4924 Affected file is lib/silcclient/ops.h and all applications
4925 using the client operations.
4927 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Moved the calling of ops->connect() from connect_to_server_final
4930 into receive_new_id functin since that is the point when the
4931 client is actually allowed to send traffic to network. The
4932 affected file is lib/silcclient/client.c.
4934 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4937 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4938 (if needs broadcasting) instead of broadcasting the packets one
4939 by one which would make a burst in the network traffic.
4941 * Added `broadcast' argument to the functions in silcd/server.[ch]
4942 silc_server_create_new_channel[_with_id] to indicate whether
4943 to send New Channel packet to primary router.
4945 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Added new function into the silcd/server.[ch] files:
4948 silc_server_create_new_channel_with_id to create new channel with
4949 already existing Channel ID.
4951 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4952 lib/silccore/silcpacket.h. This packet is used t send list of
4953 Set Mode payloads inside one packet. Server uses this to set
4954 the modes for the channels and clients on those channels, that it
4955 announced to the router when it connected to it. The protocol
4956 specification has been updated accordingly.
4958 * The silc_server_new_channel did not handle the packet coming
4959 from normal server as it normally does not send that. However,
4960 when it announces its channels it does send it. Implemented
4961 the support for that.
4963 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4964 into the file lib/silccore/id.h.
4966 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Fixed memory leaks in the functions silc_idlist_del_client,
4969 silc_idlist_del_channel and silc_idlist_del_server in the file
4970 silcd/idlist.c. All of those leaked like a sieve.
4972 * Fixed some small memory leaks in the client's function
4973 silc_client_notify_by_server.
4975 * Added functions into silcd/server.c: silc_server_announce_clients,
4976 silc_server_announce_channels and silc_server_announce_server.
4977 These functions are used by normal and router server to announce
4978 to its primary router about clients, channels and servers (when
4979 router) that we own. This is done after we've connected to the
4982 These functions effectively implements the following packet types:
4983 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4984 and SILC_PACKET_NEW_ID_LIST.
4986 * Added new functions into the silcd/packet_receive.[ch]:
4987 silc_server_new_id_list, silc_server_new_channel_list and
4988 silc_server_new_channel_user_list to handle the incoming
4989 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4991 * Added support of changing Channel ID in the function
4992 silc_server_replace_id. If the server that announces a channel
4993 to the router already exists in the router (with same name but
4994 with different Channel ID), router is responsible to send
4995 Replace ID packet to the server and force the server to change
4996 the Channel ID to the one router has.
4998 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4999 client that the Channel ID has been changed by the router. The
5000 normal server sends this to the client. Client must start using
5001 the new Channel ID as the channel's ID.
5003 Implemented handling of this new type into lib/silcclient/client.c
5004 into the function silc_client_notify_by_server.
5006 * Added new function silc_idlist_replace_channel_id into the files
5007 silcd/idlist.[ch] to replace the Channel ID.
5009 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Call silc_server_command_identify_check always when processing
5012 the IDENTIFY command in silcd/command.c
5014 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5017 send keepalive packets. The packet can be sent by clients,
5018 servers and routers.
5020 Added function silc_socket_set_heartbeat into the file
5021 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5022 If not set, the heartbeat is not performed. The actual
5023 heartbeat is implemented in the low level socket connection
5024 library. However, application is responsible of actually
5027 Added silc_server_send_heartbeat to send the actual heartbeat
5028 packet into silcd/packet_send.[ch]. Server now performs
5029 keepalive with all connections.
5031 * Added silc_task_get_first function into lib/silcutil/silctask.c
5032 to return the timeout task with shortest timeout. There was a bug
5033 in task unregistration that caused problems. TODO has been
5034 updated to include that task system must be rewritten.
5036 * The client library will now resolve the client information when
5037 receiving JOIN notify from server for client that we know but
5038 have incomplete information.
5040 * Rewrote parts of silc_server_remove_from_channels and
5041 silc_server_remove_from_one_channel as they did not remove the
5042 channel in some circumstances even though they should've.
5044 * Encryption problem encountered in server:
5046 The LEAVE command used to send the Channel Key packet to the
5047 router immediately after generating it. However, the code
5048 had earlier sent Remove Channel user packet but not immediately,
5049 ie. it was put to queue. The order of packets in the router
5050 was that Channel Key packet was first and Remove Channel User
5051 packet was second, even though they were encrypted in the
5052 reverse order. For this reason, MAC check failed. Now, this
5053 is fixed by not sending the Channel Key packet immediately but
5054 putting it to queue. However, this is more fundamental problem:
5055 packets that are in queue should actually not be encrypted
5056 because packets that are sent immediately gets encrypted
5057 actually with wrong IV (and thus MAC check fails). So, packets
5058 that are in queue should be encrypted when they are sent to
5059 the wire and not when they put to the queue.
5061 However, the problem is that the current system has not been
5062 designed to work that way. Instead, the packet is encrypted
5063 as soon as possible and left to the queue. The queue is then
5064 just purged into wire. There won't be any fixes for this
5065 any time soon. So, the current semantic for packet sending
5068 o If you send packet to remote host and do not force the send
5069 (the packet will be in queue) then all subsequent packets to the
5070 same remote host must also be put to the queue. Only after the
5071 queue has been purged is it safe again to force the packet
5074 o If you send all packets immediately then it safe to send
5075 any of subsequent packets through the queue, however, after
5076 the first packet is put to queue then any subsequent packets
5077 must also be put to the queue.
5079 Follow these rules and everything works fine.
5081 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Added new function silc_server_remove_clients_by_server to
5084 remove all client entries from ID list when the server connection
5085 is lost. In this case it is also important to invalidate all
5086 client entires as they hold the invalid server entry. This
5087 fixes fatal bug when server has lost connection and will reconnect
5090 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Made some sanity checks to silc_server_daemonise like to check
5093 whether the requested user and group actually exists.
5095 * Added sanity check to SKE's silc_ske_responder_finish to check
5096 that the public and private key actually is valid.
5098 * Invalidate the client's nickname when receiving Replace ID
5099 packet and the Client ID is being replaced. This means that the
5100 server will query the nickname if someone needs it (client)
5103 * Sort the ID Cache in client library when the ID Cache data
5104 has changed (needs sorting).
5106 * Do not allow for SILC client to create several connections to
5107 several servers. The client does not support windows right now
5108 and generating multiple connections causes weird behaviour.
5110 Irssi-silc client does support windows and can handle several
5111 connections without problems, see: www.irssi.org and SILC plugin.
5113 * Fixed some places where client was added to the IDList. The
5114 rule of thumb is following (in order to get everything right):
5115 If the client is directly connected local client then the
5116 `connection' argument must be set and `router' argument must be
5117 NULL to silc_idlist_add_client function. If the client is not
5118 directly connected client then the `router' argument must
5119 bet set and the `connection' argument must be NULL to the
5120 silc_idlist_add_client function.
5122 * The funtion silc_server_packet_send_local_channel actually did
5123 not check whether the client was locally connected or not. It
5124 does that now. Fixed a bug related to LEAVE command.
5126 * Fixed Remove Channel User payload parsing bug in server's
5127 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5129 * The server's silc_server_save_channel_key now checks also the
5130 global ID list for the channel as it might not be in the local
5131 list. Fixed a bug related to LEAVE command.
5133 * Is this the end of the [<unknown>] buglet that has been lurking
5134 around for a long time? A little for loop fix in server's
5135 silc_server_command_whois_parse that is used by both IDENTIFY
5136 and WHOIS command. At least, this was a clear bug and a cause
5137 of one type of [<unknown>] buglet.
5139 * WHOIS and IDENTIFY commands call the function
5140 silc_server_command_[whois/identify]_check function even if
5141 we are not router server.
5143 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Added --with-gmp configuration option. If set the GMP
5146 is always compiled in the SILC source tree. If not set then
5147 it is checked whether the system has the GMP3 installed. If
5148 it has then the GMP won't be compiled (the system's headers
5149 and library is used), if it doesn't have it then the GMP is
5150 compiled in the SILC source tree.
5152 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Changed RSA private exponent generation to what PKCS #1
5155 suggests. We try to find the smallest possible d by doing
5156 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5157 not security fix but optimization.
5159 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5161 * Added new config entry [Identity] to fork the server and run
5162 it as specific user and group. A patch from Bostik.
5164 * Imported Dotconf configuration library into lib/dotconf.
5165 This will be used to create the SILC configuration files later.
5166 It will appear in the distsribution after this commit.
5168 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * A big code auditing weekend happening. Auditing code for
5171 obvious mistakes, bugs and errors. Also, removing any code
5174 Removed files for being obsolete:
5176 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5177 inline in the file lib/silcutil/silcbuffer.h)
5179 o lib/silcutil/silcbufutil.c (the header has inline versions)
5181 Changed code to fix possible error conditions:
5183 o The buffer formatting routines now check that the destination
5184 buffer really has enough space to add the data. This applies for
5185 both buffer formatting and unformatting
5186 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5187 unformatting was changed to accomodate following rules:
5188 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5189 sent to the function while XXX_*STRING will not allocate or copy
5190 the data into the buffer. Instead it sets the pointer from the
5191 buffer into the pointer sent as argument (XXX_*STRING used to
5192 require that the pointer must be allocated already). This change
5193 makes this whole thing a bit more consistent and more optimized
5194 (note that the data returned in the unformatting with XXX_*STRING
5195 must not be freed now). The routines return now -1 on error.
5197 o Tried to find all code that use buffer_format and buffer_unformat
5198 and added return value checking to prevent formatting and
5199 especially unformatting errors and possible subsequent fatal
5202 o Changed ske->x and ske->KEY to mallocated pointers in
5203 lib/silcske/silcske.h. Fixed possible data and memory leak.
5205 o Added return value checking to all *_parse* functions. Fixed
5206 many memory leaks as well.
5208 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5209 so that buffer overflows would not happen. All code now also
5210 checks the return value as it can fail.
5212 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5214 * Added reconnection support to server if the normal server looses
5215 its connection to the router (for example if router is rebooted).
5216 The server performs normal reconnection strategy implemented
5217 to the server. Affected file silcd/server.c.
5219 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Added new packet type SILC_PACKET_SET_MODE that is used to
5222 distribute the information about changed modes (for clients,
5223 channels and clients channel modes) to all routers in the
5224 network. Updated the protocol specification accordingly.
5226 Added functions into silcd/packet_send.c and
5227 silcd/packet_receive.c: silc_server_send_set_mode,
5228 silc_server_set_mode.
5230 Added new files silcmode.[ch] into lib/silccore that implements
5231 the encoding and decoding of Set Mode Payload. Added new type
5232 SilcSetModePayload. Moved the definitions of different modes
5233 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5235 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Oops, a little mistake in server's connection authentication
5238 protocol. The protocol is not ended with FAILURE but with
5239 SUCCESS if the authentication is Ok. :) Affected file is
5242 * Implemented NICK_CHANGE notify handling in server in the file
5243 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5244 the local clients on the channel. After the changing nickname
5245 in router environment snhould work and the [<unknown>] nickname
5246 should appear no more.
5248 The silc_server_replace_id function that receives the Replace ID
5249 payload now sends the NICK_CHANGE notify type also in the file
5250 silcd/packet_receive.c
5252 * Changed WHOIS and IDENTIFY command to support the maximum amount
5253 of arguments defined in protocol specs (3328 arguments). This
5254 fixed a bug that caused problems when there were more than three
5257 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5259 * Added extra parameter, command identifier, to the
5260 silc_client_send_command so that explicit command identifier
5263 Changed that ID list routines uses specific command identifier
5264 when sending WHOIS/IDENTIFY requests to the server so that they
5265 can be identified when the reply comes back.
5267 Affected files lib/silcclient/command.[ch],
5268 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5270 * Added `sender' argument to silc_server_packet_send_to_channel
5271 to indicaet the sender who originally sent the packet to us
5272 that we are now re-sending. Ignored if NULL. Affected file
5273 silcd/packet_send.[ch].
5275 * Added some server statistics support in silcd/server_internal.h
5276 SilcServerStatistics structure and around the server code. Also
5277 send some nice statistics information when client is connecting
5280 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Fixed channel ID decoding in server's JOIN command reply in
5283 silcd/command_reply.c
5285 * Fixed braodcasting of replace ID payload to not to send it if
5286 we are standalone server in silcd/packet_receive.c.
5288 * Fixed all channel message sending routines to not to send
5289 packets to clients that has router set, since they are routed
5290 separately in the same function earlier. Affects file
5291 silcd/packet_send.c and all channel packet sending functions.
5293 * In USERS reply, res_argv[i] are not allocated, the table
5294 is allocated. Thus changed that free the table, not its
5297 * In server's whois_check and identify_check if the client is
5298 locally connected do not send any WHOIS commands - they are not
5301 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Fixed some minor bugs in client when sending WHOIS command. The
5304 arguments was in wrong order.
5306 * Removed statis function add_to_channel from server in
5307 silcd/command.c that was previously used with the joining but
5310 * Tested USERS command in router environment successfully with two
5311 routers, two servers and two clients.
5313 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * Reorganized the USERS command and command reply in client library
5316 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5317 When the command is given by user we register a pending command
5318 callback that will reprocess the command after the reply has been
5319 received from the server. When reprocessing the packet we then
5320 display the information. Thus, the USERS information is displayed
5321 now in the command callback instead of in the command reply
5322 callback. The processing of the command is same as previously
5323 when server has sent the command reply in the JOINing process.
5325 * Added to USERS command in silcd/command_reply.c to join the client,
5326 we didn't use to know about, to the channel after we've created
5327 a client entry for it. Also, for clienet we did know already still
5328 check whether it is on the channel or not and add it if not.
5330 * Removed silc_server_command_join_notify as the function and its
5333 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * Changed the client's pending command handling to the same as the
5336 server's pending command handling. It is also now possible to
5337 execute command reply functions from other command reply
5338 function as the function callbacks for commands and command
5339 replies are one and same. The pending commands are not static
5340 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5341 in client connection context. Thus, pending commands are server
5342 connection specific as it is convenient.
5344 Changed the function silc_client_command_pending and
5345 silc_client_command_pending_del and added new function
5346 silc_client_command_pending_check. Removed the
5347 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5350 * Added cmd_ident, current command identifier, to the client
5351 connection context in lib/silcclient/client.h to keep track on
5352 command identifiers used in command sending. Client's command reply
5353 function handling now supports the mandatory command identifiers.
5355 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5356 funtions in client to fully support pending command callbacks.
5358 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5359 as one of the arguments to the application in the command reply
5362 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5363 before first releasing SILC but came back. Now it is removed again
5364 and should come back nomore. The FORWARDED flag was used only
5365 by the JOINing procedure by forwarding the command packet to router.
5366 Now, the JOINing procedure has been changed to more generic (due
5367 to various router environment issues) and FORWARDED is not needed
5368 anymore for anything. The protocol specification is yet to be
5371 Now, removed silc_server_packet_forward from server and the flag
5372 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5374 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Renamed NAMES command to USERS command. The NAMES was named that
5377 due to historical reasons. Now it is renamed. Also, rewrote
5378 parts of the USERS command. The nickname list is not sent anymore
5379 by the server. Only Client ID and mode lists are sent in the USERS
5380 command. Changed this also to the protocol specification.
5382 The client now resolves the names and stuff after it receives
5383 the USERS list from the server when joining to the channel.
5385 * WHOIS and IDENTIFY commands has been changed to support multiple
5386 Client ID's per command. One can now search for multiple users
5387 in the network by sending only one WHOIS or IDENTIFY command.
5388 Changed the code and the protocol specifications.
5390 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5391 uses silc_server_command_whois_parse to parse the request. */
5393 * If normal server, do not parse the WHOIS and IDENTIFY requests
5394 before sending it to the router. Saves some time.
5396 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5398 * Fixed JOIN command on client library. Wrong number of arguments
5399 used to crash the client.
5401 * Added silc_server_channel_has_global function to check whether
5402 channel has global users or not.
5404 * Added silc_server_channel_has_local function to check whether channel
5405 has locally connected clients on the channel.
5407 * The silc_server_remove_from_one_channel now checks whether the
5408 channel has global users or not after given client was removed from
5409 the channel. It also checks whether the channel has local clients
5410 on the channel anymore. If it does not have then the channel entry
5411 is removed as it is not needed anymore.
5413 * The silc_server_notify now checks on JOIN notify whether the joining
5414 client is one of locally connected or global. If it is global then
5415 the channel has now global users on the channel and that is marked
5416 to the channel entry. Also, it now saves the global client to
5417 global list who is joining and JOINs it to the channel. This is
5418 for normal server, that is.
5420 Changed silc_server_send_notify_on_channel,
5421 silc_server_packet_relay_to_channel and
5422 silc_server_packet_send_to_channel check if we are normal server
5423 and client has router set (ie. global client) do not send the
5424 message to that client, as it is already routed to our router.
5426 * Implemented LEAVE notify type handling in silc_server_notify
5429 * Tested LEAVE command in router environment successfully. Tested
5430 with two routers, two servers and two clients.
5434 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5436 * Implemented SIGNOFF notify type handling in silc_server_notify
5439 * silc_server_remove_id now removes the client entry from all channels
5440 it has joined and thusly sends SIGNOFF notify type.
5442 * Rewrote the NAMES list generation in server by removing two excess
5443 loops. The lists are created now inside one loop.
5445 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * silc_server_remove_channel_user checks now also global list
5448 for channel and client.
5450 * silc_server_new_channel_user checks now both local and global
5451 list for channel and client. Fixed a bug in client id decoding.
5452 Used to decode wrong buffer.
5454 * silc_server_channel_message checks now both local and global
5455 list for channel entry.
5457 * Tested channel joining (hence JOIN) in router environment
5458 successfully. Tested with two routers, two servers and two
5461 * Tested channel message sending in router environment successfully.
5463 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * Added silc_server_save_channel_key into server.[ch] to save the
5466 received channel key in Channel Key payload processing. It is
5467 also used in JOIN command reply handling.
5469 Equivalent function silc_client_save_channel_key added into
5470 client.[ch] into client library.
5472 * Changed JOIN command reply to send information whether the channel
5473 was created or not (is existing already) and the channel key
5474 payload. Changed protocol specs accordingly.
5476 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5477 the request was sent by ID and not by nickname. Crashed on
5480 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5483 now correctly save the received data.
5485 * silc_server_free_sock_user_data now notifies routers in the
5486 network about entities leaving the network.
5488 At the same time implemented functions silc_server_remove_id
5489 and silc_server_send_remove_id to receive and send REMOVE_ID
5490 packets. The packet is used to notify routers in the network
5491 about leaving entities. The ID removed will become invalid in
5494 * Added function silc_idlist_del_server into server. Removes and
5495 free's server entry from ID list.
5497 * silc_server_private_message function now checks, if we are router,
5498 that the destination ID really is valid ID, naturally.
5500 * In router when NEW_ID packet is received (for new client) the
5501 hash of the Client ID is saved in the ID Cache but the
5502 client->nickname is set to NULL, instead of putting the hash
5505 IDENTIFY command now also checks that client->nickname must be
5506 valid. If it is not if will request the data from the server who
5507 owns the client. Added new function
5508 silc_server_command_identify_check.
5510 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5511 to set the command to already allocated Command Payload.
5513 * Tested private message sending in router environment with two
5514 routers, two servers and two clients. Fixed minor bugs and now
5517 * Fixed segfault from client's NAMES command. Used to crash if
5520 * Forwarded packets must not be routed even if it is not destined
5521 to the receiver. Changed server code comply with this.
5523 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Added `require_reverse_mapping' boolean value to ServerParams
5526 structure. If TRUE (not default) the server will require that
5527 the connecting host has fully qualified domain name.
5529 If the reverse mapping is not required and hostname could not be
5530 found the IP address is used as hostname.
5532 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5534 * Implemented version string checking to both client and server.
5535 The check is incomplete currently due to the abnormal version
5536 strings used in development version of SILC.
5538 * Changed all command functions in server to use the new
5541 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Changed char *data to unsigned char *data in ID Cache system to
5544 support binary data as ID Cache data. Changed code to support
5545 binary data in lib/silccore/idcache.c.
5547 * Renamed silc_server_packet_relay_command_reply to
5548 silc_server_command_reply as it is normal packet receiving
5549 function. Rewrote the function to accept command replys for
5550 servers and not only for clients.
5552 * Mark remote router always as registered server if we are connecting
5553 to it. Otherwise, commands sent by the router to us are ignored.
5555 * All ID List find routines now returns the ID Cache Entry pointer
5556 as well if requested.
5558 * WHOIS command works now in router environment, tested with two
5559 routers, two servers and two clients.
5561 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5562 in router environment (as it is almost equivalent to WHOIS) but
5563 hasn't been tested thoroughly. Added new functions:
5565 silc_server_command_identify_parse
5566 silc_server_command_identify_send_reply
5567 silc_server_command_identify_from_client
5568 silc_server_command_identify_from_server
5570 * Disabled route cache adding because adding two different ID's with
5571 same IP replaces the old cache entry thus giving wrong route.
5572 The entry->router->connection is always the fastest route anyway
5573 so route cache may not be needed. Of course, new routes maybe
5574 established after receiving the ID when the entry->router->connection
5575 might not be anymore the most optimal.
5577 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Add route cache for received ID for fast routing.
5581 * Added silc_server_packet_route to route received packet on router
5582 that is not destined to us.
5584 * Renamed silc_server_get_route to silc_server_route_get.
5586 * Added id_string and id_string_len fields into SilcServer to
5587 include encoded ServerID for fast comparing without excess
5588 encoding of the ID's.
5590 * Cleaned up WHOIS command on server side. Added following static
5593 silc_server_command_whois_parse
5594 silc_server_command_whois_check
5595 silc_server_command_whois_send_reply
5596 silc_server_command_whois_from_client
5597 silc_server_command_whois_from_server
5599 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5600 arguments in command replies. All command functions should be
5601 updated to use this macro.
5603 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Minor typo fixes on command reply handling on server.
5607 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Added silc_server_command_add_to_channel internal routine to add
5610 the client to the channel after router has created the channel and
5611 sent command reply to the server.
5613 * Added generic silc_server_send_command to send any command from
5616 * Use static buffer with ID rendering instead of duplicating data.
5618 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Fixed a channel user mode bug when joining to a channel server gave
5621 everybody channel founder rights, oops.
5623 * We mark ourselves as the router of the incoming server connection
5624 if we are router ourselves. This way we can check in some packet
5625 sending functions whether it is locally connected server. For
5626 incoming router connections we put NULL.
5628 * For router sending packets locally means now always sending the
5629 packet cell wide; to local clients and local servers. For normal
5630 server sending packet locally means sending it to only local
5633 * Fixed the JOIN command to really work in router environment. If the
5634 channel is created it is always created by the router. Router is
5635 also responsible of making the initial joining to the channel,
5636 sending JOIN notify to the sending server and distributing
5637 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5638 does not exist server doesn't do anything else but forward the
5639 command to the router which performs everything.
5641 * Added silc_server_send_channel_key function to send the Channel Key
5644 * Added silc_server_create_channel_key to create new channel key. The
5645 channel key is now re-generated everytime someone joins or leaves
5646 a channel, as protocol dictates. Note: channel->key_len is the
5649 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5652 packet_receive.[ch] to separate packet sending and receiving
5653 routines. The server.[ch] now includes everything else including
5654 actual packet processing (writing and reading data) and other
5657 Renamed silc_server_private_message_send_internal to
5658 silc_server_send_private_message. The routine is still though
5659 used only to relay private messages as server does not send
5660 private messages itself.
5662 Renamed silc_server_new_channel to silc_server_create_new_channel
5663 and added new function sicl_server_new_channel that handles the
5664 incoming New Channel packet. Added also new sending function
5665 silc_server_send_new_channel to send New Channel Payload.
5667 * Added new function silc_server_notify to process incoming notify
5668 packet to the server/router. Server may then relay the notify
5669 to clients if needed.
5671 * Added new function silc_server_new_channel_user to process incoming
5672 New Channel User packet. Router will redistribute the packet and
5673 send JOIN notify to its local clients and locally connected servers
5674 if needed. Normal server will send JOIN notify to its local client
5675 on same channel when received this packet. Added also corresponding
5676 sending function silc_server_send_new_channel_user to sent the
5679 * Added boolean route argument to send_notif_to_channel and
5680 packet_send_to_channel functions to attempt to route the packet
5681 if it is TRUE and send only locally if it is FALSE.
5683 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * silc_server_replace_id now broadcasts the received replace ID
5686 packet if it is not broadcast packet already. The router must
5687 broadcast to inform other routers about changed ID.
5689 * Added backpointer to server's router into SilcServer context in
5690 silcd/server_internal.h.
5692 * Fixed silc_server_packet_broadcast to send correct broadcast
5695 * The channel key is now distributed to the local client as soon
5696 as it is received from the router (in router environment) so that
5697 no other packet may be sent for the channel until client has
5700 * silc_server_remove_channel_user now broadcasts the received
5701 Remove Channel User packet if it is not broadcast packet already.
5702 The router must broadcast to inform other routers about removed
5705 * Added users field into SilcPacketContext that is a reference count
5706 of the context. One can increase the reference count by calling
5707 silc_packet_context_dup which is now changed to just increase the
5708 reference count instead of duplicating the data. The reference
5709 count is decresed by calling silc_packet_context_free that will
5710 free the data after the reference count hits zero.
5712 For now on the packet context and everything allocated into it
5713 (including the raw packet from network) must be freed by calling
5714 the new silc_packet_context_free function. Added also new function
5715 silc_packet_context_alloc that must be used now to allocate the
5716 context. This also means that if a routine is asynchronous from
5717 silc_[client/server]_packet_parse_type the packet context must
5718 be duplicated by calling silc_packet_context_dup. Otherwise it
5719 gets free'd after silc_[client/server]_packet_parse_type returns.
5720 Also, one must remember that if packet is duplicated then its
5721 reference count must be decresed by calling the free function as
5722 many times as it was duplicated.
5724 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5725 from both client and server.
5727 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Made joining to a channel working in router environment.
5731 * Cleaned up JOIN command on server side and create function
5732 silc_server_command_join_channel internal routine to make the
5735 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Changed silc_command_pending list to SilcDList. Also, added
5738 `ident' field to SilcServerCommandPending structure to identify
5739 the reply and to call correct callback.
5741 Added silc_server_command_pending_check function to replace the
5742 corresnponding macro. The silc_command_pending list is not
5745 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5746 to set identifier to previously allocated Command Payload. It
5747 is used to set identifier for command when resending Command
5750 * Added silc_command_payload_encode_payload to encode Command
5751 Payload buffer from SilcCommandPayload structure.
5753 * Added silc_argument_payload_encode_payload to encode Argument
5754 payload buffer from SilcArgumentPayload structure.
5756 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5758 * Changed WHOIS command to support router connection on server side.
5759 The whois request is always sent to router unless the server is
5760 standalone server. After server has received the reply from the
5761 router will it send the reply to the client.
5763 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5764 broadcast received broadcast packet. The function is used only
5765 by router. The broadcast packet is always sent to the router's
5768 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5769 render given ID to printable string, for log files for example.
5771 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Made basic router to router connections working. At least they
5774 can now connect to each other but nothing really works the way
5775 they are supposed - yet.
5777 * Added new initiator token to RouterConnection configuration
5778 file in silcd/serverconfig.[ch]. It is used to tell whether we
5779 are the initiator to the remote router or whether we'll expect
5780 the other end to connect.
5782 * Moved registering of listener task to silc_server_init, hence
5783 the server starts listenning as soon as it is run, even if it
5784 does not have connections to other routers. Let's see how well
5787 * Changed default connection retry timeouts for more suitable in
5790 * Removed cipher and such arguments from silc_idlist_add_client
5791 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5792 Added new function silc_idlist_add_data to add the keys and stuff
5795 * Added SilcIDListData structure and added it to SilcClientEntry
5796 and SilcServerEntry as their first field in the structure. This
5797 way we can explicitly cast the ID entries to the SilcIDListData
5798 structure and get common data for the entries. In past, we had
5799 to first check what type of connection it is and then cast it to
5800 correct ID entry type. Now, we can directly cast the opaque
5801 pointer to the SilcIDListData (no matter what ID entry it actually
5802 is) and get the data needed.
5804 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5807 in some circumstances even if threre were timeout tasks, though not
5808 IO tasks, but tasks anyway. Now fixed.
5810 * Defined SilcServerConnection structure to hold connection specific
5811 stuff about directly connected servers and routers. The definition
5812 is currently in silcd/server_internal.h. I thought about having
5813 a bit more important role fro this struct but for now it is used
5814 only when connecting to other server (or router actually).
5816 * Added connecting retry support in server when connecting to
5817 router(s). The retry feature implement exponential backoff
5818 algorithm. Also, added SilcServerParams structure to hold default
5819 parameters for server. For now, it include these retry settings
5820 and are hard coded. After server is moded to be as Silc Server
5821 Library this structure will be more important.
5823 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Changed client librarys channel->clients table to SilcList and
5826 changed code accordingly.
5828 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5830 * Changed client's channel table to SilcList and changed code
5831 accordingly. Also changed SilcChannelClientEntry to include back-
5832 pointer to the channel so that client entry can use that structure
5833 as list as well and we have fast cross-reference to the channel.
5834 This change dramatically decreased the complexity of channel
5835 handling with client entry and vice versa (removed one extra
5836 loop when searching for channel entry from many functions).
5838 * Changed server->sim from table to SilcDList and changed code
5841 * NAMES command can now be used from user interface. It will show
5842 the user list on the channel, neatly.
5844 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5845 Code now saves realname of the user if it becomes available.
5847 * Renamed configure.in to configure.in.pre and made ./prepare
5848 script to automatically add correct version string to
5849 configure.in which it creates from configure.in.pre.
5851 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * NAMES command reply now shows users mode with the nickname when
5856 * Moved silc_client_ch[u]mode[_char] functions from
5857 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5858 place sucks, they are utility functions and should be in some
5861 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5863 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5866 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Added TRQ (efficient deque and list library) into lib/trq. This is
5871 a very good list library that is currently used in the SILC. Defined
5872 SilcList API over the library because I didn't like the API very
5873 much. See lib/trq/silclist.h for the API and examples of how to
5874 use the API. Fixed various places in the code to use the new
5875 SilcList API. The SilcList is meant for lists that has a structure
5876 already defined as a list. It is not suitable to add just some
5877 context to the list (in TRQ, the context is the list actually).
5879 So, I defined SilcDList that can be used for the purpose where
5880 predefined list structure does not exit. This can be used as
5881 such list. Now some context just can be added to the SilcDList.
5882 Currently this list is not used in the SILC just yet, though there
5883 are a lot places where this can replace dynamically allocated
5884 tables and I will fix these places, later, to use SilcDList.
5885 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5886 and use TRQ internally).
5888 Also fixed some annoying warning messages that the original TRQ
5889 code generated. Also minor changes to TRQ's Makefile.in.
5891 * Added support for querying by Client ID to both WHOIS and
5892 IDENTIFY commands into server, as required by the protocol.
5894 * Removed method function pointers from SilcBuffer structure. They
5895 weren't used to anything and just increased the context size for
5896 no good reason. This change also made silc_buffer_alloc and
5897 silc_buffer_free functions inline functions.
5899 * Disabled command flooding detection support until it's fixed so
5900 that it accepts commands in but does not execute them more than once
5903 * Added silc_net_localhost(), to return local hostname, into
5904 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5905 that must be initialized before calling silc_client_init.
5907 * Added new function: silc_server_send_notify_on_channels to send
5908 notify messages to all channels client has joined. It is assured
5909 that the message is sent only once per client.
5911 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5912 lib/silcutil/silcutil.[ch] as silc_format function. The new
5913 function is generic and is used by server as well, not only by
5914 the logging routines.
5916 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5917 the provided version string was not acceptable. Added new function:
5918 silc_ske_check_version into lib/silcske/silcske.h. The function
5919 must be implemented by the application (client or server) and it
5920 does not reside in the SKE library. The function checks the version
5921 string remote end sent.
5923 * Added back pointers (to opaque context and to SilcSocketConnection)
5924 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5926 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5927 duplicate packet context structure.
5929 * Changed `notify' client operation to send same arguments as client
5930 receives from server except for ID's. ID's are mapped to correct
5931 ID entry and that is returned. Also, if channel entry is not sent
5932 by server but the notify is for channel the channel entry is sent
5933 to application (otherwise application doesn't know that it is for
5934 channel (library gets it from packet's Destination ID)).
5936 * Added silc_client_remove_from_channels into client library to
5937 remove a client from all channels it has joined to. Used when
5938 received SIGNOFF notify from server. Added also new function
5939 silc_client_replace_from_channels to replace old ID entry with
5940 new ID entry on all channels. Used when received NICK_CHANGE
5943 * Fixed ID Cache list handling in silc_idlist_get_client in
5944 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5945 to get (or query) client by ID.
5947 * Updated TODO list.
5949 * Added connection authentication status message defined by the
5950 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5951 support for these into the code in client and server side.
5953 * Added generic function silc_client_send_command to send any command
5954 with variable argument list. Application should use this function
5955 to send commands if the command functions provided by the library
5956 does not suite for the application's user interface needs.
5958 * Added new `failure' client operation. Application is notified about
5959 received failure packet if client is executing a protocol. In this
5960 case the protocol's execution has failed.
5962 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5963 is required by the protocol.
5965 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5966 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5969 * Added status flag to SilcSKE object to indicate realtime status
5970 of the SKE protocol.
5972 * Application receives now exactly same command reply arguments as
5973 the library receives from server. However, if ID is received the
5974 corresponding ID entry is returned to the application (eg. Client
5975 ID is mapped to correct SilcClientEntry entry and that is returned).
5976 Changed command_reply client operation due to this change.
5978 * Changed all ID's in commands and in command replys as ID Payloads.
5979 Change affected both client and server side codes.
5981 All ID's sent in SILC network (with execption of ID's in SILC
5982 Packet header) are sent in ID Payload to support variable length
5985 * Server now notifies nick changes and notifies all clients on
5986 the channels about the new nickname (about the new Client ID,
5989 * Implemented CMODE command to change channel modes. Supports all
5990 channel modes defined by the protocol specs except ban and invite
5991 lists. (Also, private channel key mode is supported but support for
5992 setting private channel key in client is missing, thus, this mode
5993 has no effect on client side (except that server requires that the
5994 client uses private channel key and normal channel traffic does not
5997 Also, invite mode works per se, but INVITE command does not work
5998 yet correctly, so you can set channel as invite only channel but
5999 inviting clients to the channel does not work (it is yet to be
6000 thought what's the best way to do it).
6002 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6003 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6004 Implemented CUMODE command to change user's mode on the channel.
6005 Supports all modes defined by the protocol specs.
6007 * Added NAMES command reply to return users modes on the channel.
6009 * Removed unnecessary and slow ciphers from lib/silccrypt.
6011 * Set SO_KEEPALIVE option to connection sockets by default.
6013 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6015 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6016 redefined the Notify Payload into protocol specs.
6018 * Added silc_id_payload_parse_id to get ID directly from raw
6021 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6024 accept searching by Client ID as well.
6026 * Added support for LEAVE and SIGNOFF notify types in client library.
6028 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6029 to parse ID Payload from raw data.
6031 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6033 * Added flags parameter into silc_ske_assemble_security_properties
6034 function in lib/silcske/silcske.[ch].
6036 * Changed notify client operation to fit better for notify messages
6037 sent by server. The notify payload received from server is now
6038 passed to the application (after parsing it to SilcNotifyPayload).
6039 It is application's responsibility to retrieve the arguments
6040 from the payload and show the message the way it wants. The message
6041 sent by server is implementation specific.
6043 * Changed public keys to comply with the protocol specification.
6044 Old public keys are not supported anymore and are not compatible.
6046 * Removed nickname from Channel Payload as the latest draft removed
6047 it. The client must resolve the nickname from the NAMES command
6048 reply received when it joined the channel.
6050 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6052 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * Fixed some errors in protocol specification drafts.
6056 * Created lib/silccore/silcnotify.c to implement Notify Payload
6057 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6058 generic payloads described by protocol specifications. The file
6059 includes implementations for ID Payload and Argument Payload.
6061 * Changed Command Payload implementation to use the new Argument
6062 Payload. Changed command_xxxx_payload to command_payload_xxxx
6063 to comply with SILC coding conventions.
6065 * Added suppport for Argument Payload handling in Notify Payload
6066 implementation as protocol requires it. Added the new support
6067 into server and client lib as well.
6069 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Added support for multiple nicknames on same channel. [n] is
6072 added locally to the nickname if there are more than one same
6073 nicknames on the channel.
6075 * Server now sends all nicknames that matched WHOIS request.
6076 Client also shows the list received from server.
6078 * Added TOPIC command to client side. User can now set and show
6079 current topic on channel.
6081 * Added MOTD command to client and server. Also, server sends the
6082 motd when client connects to the server.
6084 * Changed version strings to comply ISO 8601.
6086 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Fixed protocol error handling in client library. It should now
6089 cope even if the SKE fails for some reason.
6091 * Made new protocol specification drafts for submitting to IETF.
6093 * Implemented TOPIC command to server in silcd/command.c.
6095 * Added two new notify types into lib/silccore/silcnotify.h:
6096 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6097 notify nickname change and topic setting/change on a channel.
6099 * API change of command_reply operation in client library. The
6100 application gets now the status type received from server as well.
6102 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6104 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6106 * Cras fixed and optimized the packet handling even further and
6107 it should work now. Minor change to the prototype of function
6108 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6110 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Added new function into lib/silcutil/silcschedule.[ch]:
6113 silc_schedule_with_fd to select() a specified fd. The function
6114 returns after timeout expires or data arrives or goes. The
6115 function is used by packet routines to wait that all data is
6116 received from network.
6118 * Fixed data reading from network in lib/silccore/silcpacket.c.
6119 The code now assures that all data is read from the fd and then
6120 continues packet processing. This was a bug fix since the code
6121 used to drop some data in some circumstances.
6123 * Added new function into lib/silcclient/client.[ch]:
6124 silc_client_start_key_exchange to start key exchange after
6125 connection has been established to server. The code internally
6126 now uses this funtion but its main purpose was to provide it
6127 for applications that perform their own connecting. After
6128 application has created a connection it merely calls this
6129 function to start the key exchange between client and server.
6130 The library takes care of everything else after that.
6132 Updated also lib/silcclient/README to explain the usage of
6135 * Do not send to application information that connection has
6136 been established. Application gets notified it by connect
6139 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6141 * Applied cras's patch to add silc_schedule_one function. The
6142 function runs scheduler once and returns.
6144 * Fixed the scheduler after cras messed it up. The timeout
6145 handling works now as it's supposed to work.
6147 * Added into lib/silccore/ silcnotify.h to include notify
6148 message types support. Changed silc_server_send_notify*
6149 functions, in server.[ch], to support those new notify types.
6150 Added the support for the notify types into client library,
6151 as well. Added new notify client operation into ops.h in
6154 * Changed silc_server_packet_send_to_channel to send normal
6155 packets instead of just channel message packets. The function
6156 is now used to send the notify packets to channels. It is not
6157 used to send channel message packets anymore, as server never
6160 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6161 va_arg()s as it seems to require it nowadays. I guess, if SILC
6162 is compiled with older va_arg() the new code should work anyway.
6164 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Splitted core library. Core library (lib/silccore) includes
6167 now only SILC protocol specific core (and common) components.
6168 Created new utility library (lib/silcutil) that includes more
6169 generic purpose stuff. The stuff for util library was taken
6170 from the old core library. This was minor and easy split.
6172 * Created SILC Client Library (lib/silcclient) that includes
6173 implementation of the SILC client without user interface. This
6174 was major move from silc/ directory. The code has been changed
6175 so that it is transparent towards the user interface. The
6176 silc/ directory includes now the same user interface as before
6177 and it uses the new client library. Read lib/silcclient/README.
6178 Basicly, the client library performs everything else related
6179 to SILC except user interface handling. Also, configuration
6180 files are considered to be part of user interface and library
6181 does not handle them.
6183 This change also changed a lot of structures, function naming etc.
6184 Most important change was that SilcClientWindow object was
6185 renamed to SilcClientConnection in the client library. Created
6186 also new file lib/silcclient/ops.h. Also added new files
6187 silc/local_command.[ch] and silc/client_ops.[ch].
6189 All these changes were made to make it easier for user interface
6190 designers to create what ever user interface for the SILC client
6193 It is also expected that the server will be moved to lib
6194 directory as well and SILC Server Library will be created;
6195 sometimes in the future.
6197 * Removed Local commands from lib/silccore/silccommand.h as
6198 they are application specific and new client library does not
6199 handle any of those anymore.
6201 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6202 old client implementation in silc/.
6204 * Added support for callback functions in SILC_LOG_* macros.
6205 Application can now set its own callbacks that will be called
6206 instead of using the default functions that will always print
6207 the debug messages to stderr (or stdout). Also, debugging can
6208 now be disabled by setting silc_debug to FALSE and re-enabled by
6209 setting it to TRUE. Note, that logging will still work even
6210 if debugging is disabled.
6212 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6213 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6214 silc_log_reset_debug_callbacks.
6216 * To enable debugging in silc client one must give now -d
6217 option on command line.
6219 * Changed silc_schedule_init to automatically allocate task queues
6220 if they are not allocated before calling it.
6222 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6224 * Added GMP 3.1 into math library.
6226 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6228 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6229 a channel in SILC network. The packet is used by servers and
6230 routers to notify other routers that user has left a channel.
6231 This little feature was missing until now. Added the feature
6232 to protocol specification as well.
6234 Added functions: silc_server_send_remove_channel_user and
6235 silc_server_remove_channel_user into server.[ch].
6237 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6238 lib/silccore/silcpacket.h. However, they are not implemented
6241 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6243 * Fixed joining to a channel and sending channel messages
6244 between server and router. The channel message sending should
6245 now work inside a cell.
6247 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * Fixed the private message sending between server and router.
6250 The private message sending should now work inside a cell.
6252 * Added silc_server_replace_id into server.[ch] to replace
6253 existing ID in the SILC network.
6255 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6256 and silc_idlist_replace_server_id into idlist.[ch] in server.
6258 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Fixed the server to server connections. Server can again now
6261 connect to router. Router to router connections probably does
6264 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6266 * Added dynamic protocol registering support. Now protocols can
6267 registered and unregistered on the fly. Patch by cras.
6269 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6271 * Added lib/contrib directory to hold routines that some platforms
6272 don't have but are needed by SILC.
6274 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6275 into lin/contrib to provide getopt() and getopt_long() for
6276 those who don't have it.
6278 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * Added AWAY command to client. When away message is set and
6281 client receives a private message packet the client automatically
6282 replies to the sender with the away message.
6284 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6285 bug seemed to be the cause of recent problems when compiling
6288 * Added version detection support to SKE protocol specification
6289 and added the new changes to the SKE implementation as well.
6290 There were other minor changes in the SKE protocol as well.
6292 Many changes in lib/silcske/silcske.[ch] and in
6293 lib/silcske/payload.[ch].
6295 * Added ^U functionality, clear input line. Patch from cras.
6297 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6299 * Mainly small bugfixes on core library. Fixed some debugging
6300 logging and buffer overflow in silclog.c.
6302 * Updated config.sub and config.guess on the distribution tree.
6304 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6306 * Added command lagging support in server. Client may execute
6307 commands now only once in two seconds.
6309 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6311 * Optimized packet reception. MAC computation and checking is now
6312 also more optimized. A lot previously duplicated code is now
6313 used as generic by both client and server.
6315 * Fixed key pair generation in clientutil.c
6317 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6319 * Added into lib/silccore/silcbufutil.[ch] new function;
6320 silc_buffer_realloc.
6322 * Moved generic packet sending/encryption functions to
6323 lib/silccore/silcpacket.[ch] from client and server. Some
6324 rewriting of the functions.
6326 * Moved all generic packet reception/decryption functions to
6327 lib/silccore/silcpacket.[ch] from client and server. The
6328 packet processing is now much cleaner in both client and server.
6329 These were major changes in both client and server.
6331 * Created many common functions in server to do packet sending.
6332 Previously code were duplicated a lot, this has been removed
6335 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Rewrote major parts of the ID cache system. Don't know
6338 whether it is better now or not but at least the API is more
6341 * Major rewrite on ID cache stuff on client because of the ID
6342 cache API changes. Added idlist.c to client.
6344 * Also major rewrite on ID cache stuff on server as well.
6345 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6346 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6347 in hand, instead they are all put into the ID cache system now.
6348 All server_idlist_* routines uses ID cache now instead of
6349 traversing its own lists (those lists does not exist anymore).
6350 SilcIDList though still exists. Also, SilcXXXEntry's are
6353 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Finally made the SKE implementation compliant to the protocol
6356 specification. All mp integers are now binary encoded as
6357 opposed being HEX encoded.
6359 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6362 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6363 functions: silc_[encode/decode]_pem. Also added function
6364 silc_encode_pem_file to PEM encode with newlines ('\n') for
6367 * SILC public keys are now encoded either PEM or binary. Same
6368 option is for private keys as well. By default private keys
6369 are binary encoded and public keys PEM encoded. Silly HEX
6370 encoding were removed.
6372 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6373 function to create fingerprints.
6375 * Fixed a bug in SHA1; does not change the original data anymore.
6377 * Partly implemented INFO command on client and server side.
6378 Fixed CLEAR command. Changes to SERVER command; show current
6379 server(s) when giving command without arguments. Added
6380 VERSION command to client.
6382 * Added check to server that unregistered connections cannot
6383 execute commands (unless it is specificly allowed).
6385 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6387 * Fixed screen refresh.
6389 * Fixed channel joining bug from client. On some circumstances
6390 client tried to join to a channel it had already joined.
6392 * Added public key verification process into client's protocol.c.
6393 The client now verifies the public key from user and saves
6394 it into ~./silc/serverkeys/ directory.
6396 Added into: clientutil.[ch]: silc_client_verify_server_key.
6398 * Changed SKE protocol's silc_ske_initiator_finish function
6399 to accept callback function that verifies the received public
6400 key. Removed old silc_ske_verify_public_key function.
6402 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6405 silc_pkcs_private_key[_data]_set.
6407 * Made the password and public authentication more cleaner in
6408 server's protocol.c.
6410 * Removed historic and obsolete protocol `channel_auth' from
6411 both client and server.
6413 * Removed wrong way of sending command status messages from
6414 server to client in server's command.c. The old way violated
6415 protocol specification.
6417 Changes to silccore/silccommand.[ch]: removed
6418 silc_command_encode_status_payload -> not needed anymore,
6419 changed silc_command_encode_payload_va to accept extra
6420 argument on variable argument list. The argument type must
6421 now be provided to the function. Also, added new function:
6422 silc_command_encode_reply_payload_va which is same as
6423 normal command_encode_payload_va except command status type
6424 is provided as extra argument.
6426 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Added ~./silc directory handling. The directory includes the
6429 public and private keys for the client.
6431 Added silc_client_check_silc_dir, silc_client_create_identifier
6432 and silc_client_load_keys.
6434 * Implemented SILC protocol compliant public key. Added public
6435 and private key saving to and loading from files.
6437 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6438 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6439 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6440 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6441 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6443 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6444 silc_pkcs_load_[public/private]_key.
6446 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * Added silc_server_get_route (route.[ch]) to get connection
6449 data for the fastest route for given ID.
6451 * Implemented INVITE command on client and server. The command
6452 were re-defined in the SILC Protocol Specification and the
6453 implementation now complies with the specification.
6455 * Implemented PING command on client and server.
6457 * Implemented NAMES command on client and server. The server side
6458 supports currently only normal server not router server yet.
6459 Some changes to NAMES definition in SILC protocol specification.
6461 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6463 * Implemented LEAVE command on client and server.
6465 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6466 again. This change was made to the protocol as well. Server
6467 should not violate the protocol specification anymore.
6469 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6471 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6472 was tested. SOCKS4 was not but should work anyway.
