3 * Added silc_mime_parse function to parse MIME headers.
4 Affected files are lib/silcutil/silcstruti.[ch].
6 * Added MIME header parsing in Irssi SILC Client. It displays
7 all textual MIME objects, others it ignores. Affected file
8 is irssi/src/silc/core/clien_ops.c.
10 Wed Apr 17 22:07:59 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
12 * Fixed a bug in the pid writing function, which couldn't be
13 written in a root-owned directory.
15 Tue Apr 16 09:34:40 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
17 * Defined that channel message to unknown Channel ID must
18 cause SILC_NOTIFY_TYPE_ERROR notify message to the sender.
19 Updated the protocol specs and the code in server. The
20 affected file is silcd/packet_receive.c.
22 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
24 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
25 that it is used to send error notifys if error occurs during
26 some SILC packet processing, except commands. The error
27 types are same as for command reply types. Defined that
28 if private message is sent to unknown Client ID the error
29 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
30 Updated the protocol specs and code. Affected files are
31 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
32 lib/silcclient/client_notify.c, silcd/packet_receive.c,
33 and irssi/src/silc/core/client_ops.c. Renamed the
34 SilcCommandStatus to SilcStatus.
36 * Defined the use of extra WHOIS attributes in WHOIS command.
37 The <Requested Attributes> (defined in a separate document)
38 can be used to request additional information about user
39 not returned by standard WHOIS command. Defined that server
40 can send WHOIS command directly to client. Client provides
41 the requested attributes to the server. Updated the protocol
42 specs. Protocol TODO #4. Implementation is not done yet
45 * Renamed function silc_client_command_status_message to
46 silc_client_status_message. Affected files are

65 options to the server. Affected files silcd/serverconfig.[ch],
66 silcd/command.c and silcd/packet_receive.c.
68 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
70 * Added resolve_cmd_ident field to the SilcClientEntry structure
71 too so that if the entry is for example being resolved so
72 another command may attach to the same pending command reply
73 without requiring to resolve the same entry again. Added
74 support for adding multiple pending commands for one
75 command idenfier. Affected files lib/silcclient/command.[ch],
76 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
78 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
80 * Defined that server receives WHOIS command reply for private
81 and secret channels too. Updated protocol specs and the
82 code in server. Affected file silcd/command.c.
84 * Defined <channel user mode list> argument to WHOIS command
85 reply for returning user modes on the channels. The
86 channel list now doesn't include the user mode anymore but the
87 actual channel mode. Updated protocol specs and the code in
88 client and server. Affected files are silcd/command_reply.c,
89 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
90 and lib/silcclient/command_reply.c.
92 * Save the channels list in WHOIS command reply in normal server
93 so that WHOIS always shows joined channels also in normal
94 server and not just on router. Affected file is
95 silcd/command_reply.c.
97 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
99 * Defined that server receives USERS command reply for private
100 and secret channels too. Updated protocol specs and the
101 code in server. Affected file silcd/command.c.
103 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
105 * Changed the UMODE's mode mask argument to be optional. If
106 not provided then the command merely returns the current mode
107 mask to the client. Updated protocol specs and the server.
108 Affected file is silcd/command.c.
110 * Added SILC session detachment/resuming support. It is possible
111 to detach by closing the network connection and then re-connect
112 and resume to the old client session. Added DETACHED user
113 mode that server will set for detached client. Added new
114 packet RESUME_CLIENT which is used to perform the resuming
115 process. Added DETACH command. Updated the protocol specs,
116 core library, client and server. Protocol TODO #22. Very
117 many affected files around the tree.
119 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
121 * Changed the CMODE's mode mask argument to be optional. If
122 not provided then the command merely returns the current mode
123 mask to the client. Updated protocol specs and the server.
124 Affected file is silcd/command.c.
126 * Changed the Killer's Client ID in KILLED notify to be just
127 any ID payload since router server is allowed to kill as well.
128 Updated protocol specs, client libary and server. Affected
129 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
130 and irssi/src/silc/core/client_ops.c.
132 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
134 * Added new user modes ANONYMOUS for special anonymous servers
135 that may set the mode for client, and BLOCK_PRIVMSG which
136 client may set to block incoming private messages unless the
137 Private Message Key flag is set (using private keys to protect
138 private messages). Updated protocol specs and code in client
139 and server and core library. Protocol TODO #23. Affected
140 files are lib/silccore/silcmode.h, silcd/server.[ch],
141 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,

145 may set to itself to tell server not send channel messages.
146 Other packets such as channel key packets are still sent.
147 Protocol TODO #23. Updated the protocol specs, client and
148 server. Affected files are lib/silccore/silcmode.h,
149 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
150 lib/silcutil/silcutil.c, silcd/command.c, and
153 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
155 * Redefined the Status Payload to include now two 8 bit fields,
156 instead of one 16 bit field. This now makes it possible to
157 send list of errors. Updated the protocol specs and the code
158 in core library, client library and server. Protocol TODO #1.
159 Affected files are lib/silccore/silccommand.[ch],
160 lib/silcclient/command_reply.[ch], silcd/command.c,
161 silcd/command_reply.c and silcd/packet_receive.[ch].
163 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
165 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
166 must be handled by the application and should tell the application
167 that an error message was already printed, and it should print the
168 config coords (line, filename, ...). Affected files are
169 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
171 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
172 server config parsing code more readable.
174 Fixed a bug in the fetch_logging() config callback.

187 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
188 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
190 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
192 * Added STATS command to the protocol after all, to return
193 various statistical information about the network. It can
194 be used by clients to retrieve statistical information, and
195 servers may use it to to fetch cell and network wide
196 statistics from router. Updated the protocol specs and
197 implemented it to the server. Protocol TODO #16.
198 Affected files are lib/silccore/silccommand, silcd/command.[ch],
199 silcd/command_reply.[ch].
201 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
203 * The LIST command reply in client libary now adds new channel
204 entry if the returned channel doesn't exist yet in cache,
205 and returns the channel entry to the application in the
206 command_reply client operation. Affected file is
207 lib/silcclient/command_reply.c.
209 * Changed the channel message payload's MAC generation to
210 include the IV in the MAC as well. This way all relevant
211 parts of the channel message payload are authenticated also
212 with the channel message MAC (and not only by packet MAC).
213 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
214 Affected file is lib/silccore/silcchannel.c.
216 * Fixed the SKE to save the remote version, since the
217 silc_ske_parse_version mistakenly checked wrong version,
218 after it replaced the start payload. Affected files are
219 lib/silcske/silcske.[ch].
221 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
223 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
224 string utility functions. Added there also new functions
225 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
226 Affected files lib/silcutil/silcstrutil.[ch].
228 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
229 files are lib/silcutil/silcstrutil.[ch].
231 * Defined that the security property fields in SKE SHOULD be
232 UTF-8 encoded, defined that version string MUST be US-ASCII
233 encoded, defined that passphrases sent in connection
234 authentication protocol MUST be UTF-8 encoded. Implemented
235 these to the client and server. Defined also that other
236 passphrases sent in the protocol MUST be UTF-8 encoded.
237 Affected files are lib/silcske/silcske.c,
238 lib/silcclient/protocol.c, silcd/protocol.c,
239 silcd/serverconfig.c, and lib/silccore/silcauth.c.
241 * Changed the silc_client_close_connection interface to not
242 need the SilcSocketConnection which should not be visible
243 to application. Affected files are lib/silcclient/client.c
244 and lib/silcclient/silcclient.h.
246 * Rewrote the text for Private Message Key Payload in the
247 protocol specification. Protocol TODO #11.
249 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
251 * Upgraded the protocol version to 1.1, updated protocol specs
254 * Added the nickname as new argument to NICK_CHANGE notify and
255 added it to protocol specs and implemented it to client and
256 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
257 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
258 lib/silcclient/client_notify.c.

263 silcd/packet_receive.c, packet_send.[ch],
264 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
265 The killer's client entry is now returned to application in
266 the `notify' client operation.
268 * Fixed the Max Argument fields that had too large value set
269 in the protocol specs. Protocol TODO #14.
271 * Added the LEAVE command reply to return the ID of parted
272 channel. Updated protocol specs and implemented it to the
273 client and server. Protocol TODO #15. Affected files are
274 silcd/command.c, lib/silcclient/command_reply.c. The channel
275 entry is now returned to application in the `command_reply'
278 * Rewrote the version SKE version checking in client libary
279 and in server to use the silc_parse_version_string. Affected
280 files are lib/silcclient/protocol.c, silcd/protocol.c.
282 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
283 commands that was missing it, and updated protocol specs and
284 the server implementation. Protocol TODO #10. The affected
285 file is silcd/command.c.
287 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
288 generic reply to a generic request (REQUEST flag), and
289 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
290 way. A draft-riikonen-silc-flags-payloads-00.txt is written
291 to define the payload for DATA flag. Added the flags to
292 the implementation. Protocol TODO #9. Affected file is
293 lib/silccore/silcchannel.h.
295 Changed the client library to return the message length
296 to application as well in the channel_message and private_message
297 client operations. Affected files are
298 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
299 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
300 and lib/silcclient/client_ops_example.c.
302 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
303 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
304 the channel. Updated protocol specs and impelemented this
305 to client and server. Protocol TODO #6. Affected files are
306 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
307 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
309 Added new options m and M to CMODE command in Irssi SILC
310 client to set these modes.
312 * Deprecated all administrative commands from SILC protocol
313 since they are highly implementation specific commands.
314 Updated protocol specs. Moved the old commands in
315 implementations to private range of command types. Affected
316 files are silcd/command.c, lib/silcclient/command.c and
317 lib/silcclient/command_reply.c. Protocol TODO #8.
319 * Fixed a bug in server where sending unknown command crashes
320 the server. Affected file silcd/command.c.
322 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
324 * Added SILC_PROTOCOLVERSION macro to check protocol version
325 of a socket connection. The affected file is
326 lib/silcutil/silcsockconn.h.

331 * Do not check public key types in SKE during rekey. Affected
332 file lib/silcske/payload.c.
334 * Fixed the rekey protocol with PFS, which was totally broken.
335 Affected file silcd/protocol.c.
337 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
339 * Some client implementations quit network by doing first LEAVE
340 and then immediately SIGNOFF (like Bombyx). We now do check
341 after a short time after LEAVE notify and check whether the
342 client is still valid after LEAVE, and if not we remove it from
343 cache. Affected file is lib/silcclient/client_notify.c.
345 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
347 * Merged version 1.1.4 of zlib. Even if it not currently in use,
348 it's good not to have security holes here.
350 * Fixed a negative refcount situtuation for the config context.
351 Affected file is silcd/serverconfig.c.
353 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
355 * ROBOdoc documented lib/silcutil/silcutil.h.
357 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
359 * Optimized even more the SilcPacketContext structure. Now
360 totally saved 16 bytes of memory per context after optimization.
361 Affected files are lib/silccore/silcpacket.[ch].
363 * Made strict checks for valid SILC IDs. Affected file is
364 lib/silccore/silcid.c.
366 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
368 * Changed the object argument for silc_cipher_register,
369 silc_hash_register, silc_hmac_register and silc_pkcs_register
370 to const. Affected files are lib/silccrypt/silccipher.[ch],
371 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
373 * Changed the silc_get_username and silc_get_real_name to
374 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
376 * Fixed the Irssi SILC Client to use the silc_get_username and
377 silc_get_real_name insted of glib routines since the glib
378 routines only corrupt stack. Fixes the Irssi SILC to work in
379 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
381 * Fixed the Irssi to not use g_get_home_dir since it crashes
382 or returns garbage on cygwin and corrupts stack. Added function
383 get_home_dir to Irssi routines. Affected files are
384 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
386 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
388 * Made some structure optimizations. SFTP memory FS MemFSEntry
389 entry structure. Optimized SilcTask structure. Optimized
390 SilcPacketContext structure.
392 Affected files lib/silcsftp/sftp_fs_memory.c,
393 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
395 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
397 * And yet again reverted back the config thing since Johnny
398 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
401 * Fixed memory leaks from config object. Affected files are
402 silcd/serverconfig.[ch].
404 * Added support for adding new connections to the server in rehash.
405 After rehash they take effect.
407 Added support for changing the maximum allowed connections in
408 rehash. The number can grow but going smaller is not supported.
410 Added function silc_server_num_sockets_by_remote to the
411 silcd/server_util.[ch].
413 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
415 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
417 * Added preliminary checking during config parsing for a valid
418 public/private key and removed further checks in the code.
419 Affected files are silcd/serverconfig.[ch], server.c.
421 * Moved functions silc_server_drop() and silc_server_daemonise()
422 from server.c to silcd.c since they are stricly related to
423 the application activity.
425 * Reverted a small part of the automatic ref/unref since
426 it caused a double unref in some situations. Affected
427 files are silcd/silcd.[ch], server.c, serverconfig.c.
429 * Added some .cvsignore files in the lib directory.
431 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
433 * Fixed silc_net_gethostbyaddr to correctly resolve by
434 address. Affected file lib/silcutil/silcnet.c.
436 * Fixed the notify relaying to client. The HMAC to be used
437 with relayed packets ws wrong and caused decryption failure
438 at the client end. Affected file is silcd/packet_receive.c.
440 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
442 * Created new branch silc_protocol_1_0_branch.
444 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
446 * Changed the silc_server_config_* routines to be SilcServer
447 independent. They are now officially application specific code
448 and not part of generic server implementation. Affected files
449 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
451 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
453 * Added automatic referencing of config context in the
454 silc_server_config_alloc, and automatic unreferencing in the
455 silc_server_config_destroy. Affected files are
456 silcd/serverconfig.[ch], silcd/silcd.c.
458 * Fixed the silc_log_quick handling in the logging routines.
459 It didn't log quickly when it was TRUE. Affected file is
460 lib/silcutil/silclog.c. Also the flush delay was set even
461 if it was 0 in config file. Affected file is
462 silcd/serverconfig.c.
464 * Added support for changing key pair of the server in rehash.
465 Affected file silcd/server.c.
467 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
469 * Fixed the TOPIC_SET notify to not cras. It changed the topic
470 too early, before getting the channel entry. Affected file
471 is silcd/packet_receive.c.
473 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
475 * Added functions silc_server_config_[ref/unref], these are used
476 to prevent that the config object is destroyed.
478 No longer directly affect global variables silc_log_quick and
479 silc_log_delay, they are first cached inside the config object
480 and then applied with silc_server_config_setlogfiles().
482 silc_server_config_set_defaults() is now internal to
483 serverconfig.c, there are no reasons to show this internal stuff
486 Affected files are silcd/serverconfig.[ch].
488 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
489 fprintf's to stderr, since some code may be executed again after
490 the server went into the background. Affected files are
493 * Added rehash support. Added function silc_server_rehash() that
494 will perform all the basic tasks of the rehashing procedure.
496 * Added command line option `-x, --hexdump'. This will enable the
497 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
498 The option `--hexdump' implies `--debug'.
500 * Fixed a bad bug in the logging APIs (silcutil library) where
501 the application would crash after calling silc_log_reset_all().
503 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
505 * Fixed the KICKED notify handling in client library to
506 correctly remove the channel and all entries from the
507 channel when I was kicked. This bug crashed the client.
509 Fixed yet another but in KICKED notify handling to remove
510 the kicked client correctly from the channel.
512 Affected file is lib/silcclient/client_notify.c.
514 * Fixed a minor bug in looking up correct client entry
515 in KICKED notify in server. Affected file is
516 silcd/packet_receive.c.
518 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
519 sources correctly to distribution. Fixes --with-gmp option.
521 * Removed the manual rehashing from ID Cache, and changed it
522 to use the SILC Hash Table's auto rehash feature. Affected
523 file is lib/silccore/silcidcache.c.
525 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
527 * Fixed a bug in the silc_client_nickname_format function that
528 handles the multiple same nickname formatting. Two clients
529 with same nickname caused problems after the first one left
530 and rejoined. It didn't format the nickname correctly.
531 Affected file is lib/silcclient/idlist.c.
533 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
535 * Don't change the topic if olod topic is same as new one.
536 Affected file is silcd/packet_receive.c.
538 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
540 * Added cross-reference support to the SILC Documentation
541 generator. All types across all HTML files are now cross-
542 referenced. Affected files util/robodoc/generator.c and
543 scripts/silcdoc/silcdoc.
545 * Added file lib/silcutil/silctypes.h to include all the
546 arithmetic type definitions and some macros. Removed
547 includes/bitmove.h and moved macros to silctypes.h.
549 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
551 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
553 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
555 * Added `type' argument to silc_id_payload_parse_id function which
556 now returns the type of the ID to the sent pointer. Affected
557 file is lib/silccore/silcid.[ch].
559 * Added check for CMODE_CHANGE notify type that mode change is
560 allowed by the sender. Affected file silcd/packet_receive.c.
562 * Added check for CUMODE_CHANGE notify type that mode change is
563 allowed by the sender. Affected file silcd/packet_receive.c.
564 Added the ID type as CUMODE_CHANGE notify type as argument
565 to the `notify' client operation. Affected files are
566 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
568 * Added function silc_client_add_server to the client library.
569 Added support for resolving also channel and server info when
570 received unknown entity in notify packet. Affected files are
571 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
573 * Added function silc_command_get_status to return the command
574 status from the command reply's argument payload. Affected files
575 are lib/silccore/silccommand.[ch].
577 * Added check for KICKED notify type that the kicking is
578 allowed by the client. Affected file silcd/packet_receive.c.
580 * Created function silc_get_input which can be used to get input
581 (echo on or off) from user on command line. Affected files are
582 lib/silcutil/silcutil.[ch].
584 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
586 * Optimized silc_server_packet_relay_to_channel function.
587 Added new function silc_channel_message_payload_encrypt which
588 can be called directly if channel message payload needs to
589 be encrypted and is already encoded (no need to call _encode
590 function). Packet relaying is now done by router without any
591 extra memory allocations. Affected files are
592 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
595 * Fixed the INVITE notify handling. It took wrong arguments
596 as invite list and invite delete. Affected file is
597 silcd/packet_receive.c.
599 * Added check for TOPIC_SET notify type that the topic change is
600 allowed by the client. Affected file silcd/packet_receive.c.
602 * Added check for INVITE notify type that inviting is allowed by
603 the client. Affected file silcd/packet_receive.c.
605 * Changed the silc_server_client_on_channel to return the
606 SilcChannelClientEntry as well. Moved the function
607 silc_server_check_cmode_rights to server_util.[ch].
608 Affected files are silcd/server_util.[ch], silcd/command.c.
610 * Added function silc_server_check_umode_rights to check whether
611 changing client's user mode is allowed. Added check for
612 UMODE_CHANGE notify type that the umode change is allowed
613 by the client. Affected files are silcd/server_util.[ch],
614 silcd/packet_receive.c and silcd/command.c.
616 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
618 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
619 ID length. It ignored that ID can be IPv6 based as well.
620 Affected file lib/silccore/silcpacket.h.
622 * Fixed the silc_id_id2str and silc_id_str2id to take the
623 IPv6 address offset's into consideration. Affecte file is
624 lib/silccore/silcid.c.
626 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
628 * Fixed the internal Unix scheduler functions to check for
629 NULL context they may receive. The affected file is
630 lib/silcutil/unix/silcunixschedule.c.
632 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
634 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
635 can specify different directory with --home command line
636 parameter. Affected files irssi/src/silc/core/client_ops.c,
639 * SILC-specific commands aren't now executed if the active server
640 isn't of SILC-type, so there won't be problems with having
641 IRC and SILC protocol support in same client. Affected files
642 irssi/src/silc/core/silc-channels.c, silc-servers.c,
645 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
647 * Improved the signal support in SILC Schedule. Added new
648 function silc_schedule_signal_call which is used by application
649 to mark a signal to be called. It is now safe to perform
650 any kind of tasks in signal callbacks since it is guaranteed
651 that the application specified signal callback is called
652 after the signal is over. Affected files are
653 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
655 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
657 * Added `name' field to SilcChannelPrivateKey to represent
658 application given name for the key. Moved also the context from
659 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
660 Added the `name' argument also to the function
661 silc_client_add_channel_private_key.
663 Added function silc_client_current_channel_private_key to set the
664 current channel private key in use.
666 Added "change" command to KEY command which can be used to change
667 the current channel private key. Bound the command also to
670 Also affected files lib/silcclient/client_channel.c,
671 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
673 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
675 * Added silc_rng_get_byte_fast function in to the
676 lib/silccrypt/silcrng.[ch].
678 * Changed the interface of silc_packet_assemble and the
679 silc_packet_send_prepare. If silc_packet_assmble is now
680 called the application does not call silc_packet_send_prepare
681 because the library will call it automatically. These
682 interfaces now also return a reference to the outgoing buffer
683 which includes the assembled packet, which the application can
684 use to encrypt the packet.
686 Affected files are lib/silccore/silcpacket.[ch],
687 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
688 silcd/packet_send.c, server_backup.c and packet_receive.c.
690 * Fixed a packet sending bug on very high load, where outgoing
691 packet queue wasn't handled correctly and packets got corrupted.
692 Affected files are lib/silcutil/*/silc*sockconn.c,
693 lib/silcclient/client.c and silcd/server.c.
695 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
697 * Added macro SILC_PACKET_DATALEN which can be used during
698 packet assembling to check whether the data to be added to
699 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
700 len is truncated until it fits it.
702 Added checks for maximum length of channel message payload and
703 private message payload also.
705 Added checks for maximum packet length in server and in
708 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
709 lib/silcclient/client.c, lib/silccore/silcchannel.c and
710 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
711 lib/silcclient/client_prvmsg.c.
713 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
715 * Added silc_server_packet_queue_purge call to the
716 silc_server_disconnect_remote to assure that all data in the
717 queue before disconnecting is sent to the network. Affected
720 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
722 * Added the deleting of server's own ID cache entry to the
723 silc_server_free function. Free also everything else that
724 has been allocated in silc_server_init. The affected file
727 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
729 * Added functions silc_parse_version_string, silc_version_to_num,
730 and silc_ske_parse_version to parse SILC protocol style version
731 strings. Affected files lib/silcutil/silcutil.[ch] and
732 lib/silcske/silcske.[ch].
734 * Added new configuration params: version_protocol, version_software
735 and version_software_vendor to specify what version the remote
736 host must at least be to be able to connect to server. The vendor
737 string can be regex matched too. Added new function
738 silc_server_connection_allowed to check maximum number of allowed
739 connections, and allowed versions for incoming connections.
740 Affected files are silcd/server.c, server_util.[ch] and
743 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
745 * Added preliminary support for signals in scheduler. The
746 signals we care about are now blocked always when the scheduler
747 is locked. This way we can synchronise the use of signal with
748 scheduler. It is guaranteed that when signal occurs the scheduler
749 is not locked, and thus new tasks can be safely added to the
752 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
753 to silc_schedule_internal_init and silc_schedule_internal_uninit.
754 Added new platform specific routines
755 silc_schedule_internal_signals_[un]block and
756 silc_schedule_internal_signal_[un]register.
758 Added new functions to SILC Schedule API:
759 silc_schedule_signal_[un]register. Each signal that application
760 is going to use should be registered to the scheduler.
762 Affected files are lib/silcutil/silcschedule.[ch],
763 lib/silcutil/*/silc*schedule.c.
765 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
767 * Check for unauthenticated client and server in the
768 silc_server_new_client and silc_server_new_server functions.
769 Affected file silcd/packet_receive.c.
771 * Added function silc_string_is_ascii to check whether given
772 string is 7-bit ASCII string. Affected files are
773 lib/silcutil/silcutil.[ch].
775 * Added function silc_id_is_valid_server_id into the
776 silcd/serverid.c and added checking for valid Server ID's in
777 silc_server_new_server. The Server ID must always be based
778 on the server's public IP address.
780 * Added logging of DISCONNECT packet message in the server.
781 Affected file silcd/server.c.
783 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
785 * Changed all library interfaces that use Global RNG to also
786 accept SilcRng as argument. Affected files are
787 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
788 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
789 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
790 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
793 * Added function silc_pkcs_generate_key to the
794 lib/silccrypt/silcpkcs.[ch] for applications so that they
795 don't need to do pkcs->pkcs->init calls anymore.
797 * Remove SilcSocketConnection from the SFTP API since it really
798 wasn't needed there. The application has the information
799 saved in its contexts anyway and the SFTP layer doesn't need
800 know about it. Affected files lib/silcsft/silcsftp.h and
801 lib/silcsftp/sftp_[server/client].c.
803 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
804 The SilcSimContext is not SilcSim.
806 * Fixed possible buffer overflows in silc_id_render in the
807 lib/silcutil/silcutil.c.
809 * On EPOC the global crypto module lists are not used at all
810 in the crypto library. Added support for using the constant
811 algorithm list on EPOC. Affected files are
812 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
815 * Fixed the handling of third parameter of KICKED notify, since
816 it was mistakenly updated to SILC Protocol 1.0 even though it
817 is to be included in 1.1. Since it is not in 1.0 it is not
818 mandatory, and this fix now handles it only if it is provided,
819 and it is not error if it is not provided. Affected file
820 lib/silcclient/client_notify.c.
822 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
824 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
825 client. Affected file irssi/src/silc/core/client_ops.c.
827 * Merged with Irssi 0.8.4 from irssi.org CVS.
829 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
831 * Check for valid socket connection in client entries before
832 sending any messages. Fixes a crash, but doesn't fix some
833 other underlaying bug that is lurking there. Affected
834 file silcd/packet_send.c.
836 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
838 * $usermode, $cumode and $cumode_space expandos shouldn't do
839 anything with non-SILC server records. Affected file
840 irssi/src/silc/core/silc-expandos.c
842 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
844 * Fixed the silc_net_check_[host/local]_by_sock to support
845 IPv6 bound sockets as well. Now they can return IPv6 addresses
846 as well. Affected file lib/silcutil/silcnet.c.
848 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
849 Affected lib/silcutil/unix/silcunixnet.c.
851 * Fixed ID rendering (at least on some platforms, not NetBSD)
852 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
854 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
856 * Added silc_hash_public_key and silc_hash_public_key_compare
857 functions to be used with SilcHashTable. They can be used to
858 hash public keys and compare public keys in hash table. Affected
859 file lib/silcutil/silcutil.[ch].
861 * Added support for specifying multiple public keys for Client
862 connection section in server configuration file. This makes it
863 possible to accept multiple public keys from same host, or to
864 make a section that accepts any incoming host, and have the
865 accepted public keys listed in the section.
867 Added functions silc_sever_[find/get]_public_key, added the
868 support for this actually to all connection sections but only
869 the Client section is currently allowed to specify multiple
872 Affected files are silcd/server.c, server_internal.h,
873 command.c, protocol.c, server_util.[ch], packet_receive.c.
875 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
877 * Merged Irssi 0.8.2 from irssi.org CVS.
879 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
881 * If silc_debug is TRUE, also output standard logging messages
882 to stderr with the debug output.
884 Made silc_log_reset_all() flushing all channels before returning.
885 Also fixed some documentation typos.
887 Affected files are lib/silcutil/silclog.[ch].
889 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
891 * Fixed the server to check correctly the amount of connections
892 from single host, by checking also the type of the connection.
893 Fixed also the comparison of number of connections and number
894 of allowed connections. Affected files are silcd/server.c,
897 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
899 * Fixed the USERS command reply to save the user's mode on the
900 channel as well. Fixed JOIN command reply to check whether a
901 client is on channel already and not join it twice. Affected
902 file lib/silcclient/command_reply.c.
904 * Added new file silc-expandos.c into irssi/silc/core/ to return
905 various stuff for various signal for the statusbar etc. updating.
906 Now Irssi SILC client prints channel user modes etc. on the
909 * The user mode (like server/router operator changes) is now shown
910 on the Irssi SILC client's statusbar. The affected files are
911 irssi/src/silc/core/client_ops.c, silc-expandos.c.
913 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
915 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
916 to SILC_SCHEDULE_[UN]LOCK macros.
918 * Added more error printing to logs in server code. Affected
919 files silcd/server.c and silcd/protocol.c.
921 * Fixed -S option parsing in Irssi SILC Client. Affected file
922 irssi/src/silc/core/silc-core.c.
924 * Added silc_buffer_alloc_size function. Affected file is
925 lib/silcutil/silcbuffer.h.
927 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
929 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
930 constants. Affected files in
931 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
934 * Changed the internal SFTP Memory FS table to const. Affected
935 file lib/silcsftp/sftp_fs_memory.c.
937 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
939 * Fixed the buffer formatting and unformatting routines to
940 check the size of 64 bits types with sizeof(). Affected
941 file is lib/silcutil/silcbuffmt.c.
943 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
945 * Removed 0.6.x backwards support.
947 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
949 * Changed all integer type names:
950 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
951 to avoid collisions with other libraries using same type names
954 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
956 * Added `prefer_ipv6' argument to the functions
957 silc_net_gethostbyname[_async]. If it is TRUE it will return
958 IPv6 address over IPv4. If FALSE IPv4 address is returned
959 even if IPv6 address was found. Affected files
960 lib/silcutil/silcnet.[ch].
962 * Added support silc_net_create_connection[_async] to fallback
963 to IPv4 address if IPv6 address could not be used (like if
964 it doesn't work on a specific system). Affected file in
965 lib/silcutil/unix/silcunixnet.c.
967 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
969 * Added silc_schedule_reinit function to do the enlarging
970 of the max tasks handling capabilities of the scheduler.
971 Affected files lib/silcutil/silcschedule.[ch].
973 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
975 * Added automatic extern "C" { ... } for C++ compilers so the
976 application does not need to define them. Affected file
977 includes/silcincludes.h.
979 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
980 old name went against naming convention. Applications now
981 include "silcclient.h" instead of "clientlibincludes.h".
982 Removed includes/clientlibincludes.h, it is redundant now.
984 * Renamed includes/version.h to silcversion.h.
986 * Added really preliminary support for OS/2 into the util
987 library. Only thread & mutex API is implemented, others
988 are still to be implemented. Created the lib/silcutil/os2/
989 directory. Created also file includes/silcos2.h.
991 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
993 * Added preliminary BeOS support into the util library.
994 Created lib/silcutil/beos/, and implemented all the needed
995 functions to support SILC on BeOS. Created also file
998 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1000 * Added proper initializations to silc's irssi code, so it's
1001 now possible to load it as module. Affected files
1002 irssi/src/silc/core/silc-core.c,
1003 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1005 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1007 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1010 * Fixed the silcdoc document generator to correct generate
1011 docs from all kinds of filenames. Affected files are
1012 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1014 * ROBOdoc documented lib/silcutil/silcmemory.h.
1015 Added also new function silc_memdup.
1017 * Removed lib/silcutil/silcbufutil.h and moved those routines
1018 to the lib/silcutil/silcbuffer.h.
1020 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1022 * Added `user_count' to the SilcChannelEntry which now tells the
1023 number of users on the channel. The user count is now saved
1024 in normal server of global channels as well. Affected files
1025 silcd/server.c, idlist.h, packet_receive.c and command.c.
1027 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1028 include file utility functions.
1030 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1031 instead of calling directly OS routines.
1033 * Fixed NICK change printing in Irssi SILC Client. Fixed
1034 KICKED notify printing in Irssi SILC Client. Affected file
1035 irssi/src/silc/core/client_ops.c.
1037 * Fixed a NICK change bug in client library, to not recreate the
1038 client_entry->channels hash table everytime nick is changed.
1039 Affected file lib/silcclient/client.c.

1043 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1044 the SKE interface a bit.
1046 * Fixed padding problem in PKCS#1. The padding was not actually
1047 random since the random number generator was used incorrectly.
1048 This security bug affects only when encrypting with PKCS#1, and
1049 it is not currently used at all in SILC. SILC only use signing
1050 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1052 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1063 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1064 key_exchange_timeout, conn_auth_timeout, connections_max,
1067 Implemented all the new config settings handling in the server.
1069 Optimized the use of SKE Mutual flag usage. Use it only
1070 if connection authentication protocol is not based in public
1073 Renamed all SilcServerConfigSection* to SilcServerConfig*
1074 to have a bit shorter names.
1076 Affected files silcd/serverconfig.[ch], server.[ch], and
1079 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1105 Affected files are silcd/serverconfig.[ch].
1107 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1109 * Fixed command line parameter handling. All SILC initialization
1110 is now done in silc_core_init() which also fixes autoconnecting
1113 Affected files irssi/src/silc/core/silc-core.c,
1114 irssi/src/fe-text/silc.c.
1116 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1118 * Added new configuration options and blocks:
1119 keepalive_secs, reconnect_count, reconnect_interval,
1120 reconnect_interval_max, reconnect_keep_trying and
1121 require_reverser_lookup. Added ConnectionParam block, and
1122 implemented the connection parameters when connecting as
1123 initiator and when accepting connections as responder.

1131 algorithm parts and created new file silcalgs.conf, that
1132 is now included from the example_silcd.conf.in.
1134 * Optimized the silc_server_connect_to_router_second to take
1135 the connection configuration object from the SilcServerConnection
1136 object instead of finding it during the connecting phase.
1137 Added the configuration object to SilcServerConnection struct.
1138 Affected files silcd/server_internal.h, server.c.
1140 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1142 * Add the client on channel after it was resolved at the
1143 channel message receiving, and it was not already on the
1144 channel. Affected file lib/silcclient/client_channel.c.
1146 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1160 * Added new Passphrase and Publickey authentication methods to
1161 config file, allowing both public key and passphrase based
1162 authentication to be set at the same time.
1164 Added `prefer_passphrase_auth' setting in config file which
1165 can be used to set to prefer passwd auth if both passwd and
1166 public key is set. If not set, public key is preferred.
1167 This has effect only when being initiator (responder will try
1170 Added support for authentication with passphrase and public key
1171 at the same time. The passphrase is tried first always since
1172 it is faster to check.
1174 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1176 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1178 * Merged the new SILC Config library, with the server parsing
1179 support. Read the header file silcconfig.h or the toolkit
1180 documentation for the news. Affected files are

1203 Payload. Affected file lib/silccore/silcchannel.c.
1205 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1206 as header filenames.
1208 * Removed lib/silcclient/README and created HTML file
1209 lib/silcclient/silcclient_using.html, which is now included
1210 as part of Toolkit documentation.
1212 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1214 * Fixed CUMODE_CHANGE notify handling to change the mode of
1215 correct client. Affected file lib/silcclient/client_notify.c.
1217 * Make silc_rng_alloc fail if it cannot allocate the sha1
1218 hash algorithm. Affected file lib/silccrypt/silcrng.c.

1222 * Fixed the file transfer's key agreement payload to include
1223 zero port also if the hostname is NULL because it could not
1226 Call file transfer monitor callback now also if error occurs
1227 during key agreement protocol.
1229 Changed the silc_client_file_send interface to return the
1230 SilcClientFileError instead of session id. The session ID
1231 is returned into pointer provided as argument.
1233 Check that the file exists locally before sending the
1234 file transfer request at all.
1236 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1238 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1239 error than can occur while key agreement protocol. Affected
1240 file lib/silcclient/silcapi.h.
1242 * Fixed the event_mode CMODE handler to not crash when mode
1243 is changed and +k mode is set in the channel. Affected file
1244 irssi/src/silc/core/silc-channels.c.
1246 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1247 SILC_LOG_WARNING to give out Warning and not Error. Affected
1248 file lib/silcutil/silclog.c.
1250 * Fixed the channel message payload decryption in the function
1251 silc_channel_message_payload_decrypt to not modify the original
1252 buffer before it is verified that the message decrypted
1253 correctly. Otherwise, next time it is called with correct
1254 channel key it won't encrypt since the payload is corrupted.
1255 Affected file lib/silccore/silcchannel.c.
1257 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1269 * Fixed a bug in hash table internal routine for traversing
1270 the table with foreach callback. The current entry may
1271 become invalid in the callback but it was referenced after
1272 the callback returned.
1274 Do not allow auto rehashing of hash table during the
1275 silc_hash_table_foreach operation, for same reasons as it is
1276 not allowed for SilcHashTableList. Affected files are
1277 lib/silcutil/silchashtable.[ch].
1279 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1281 * Defined DLLAPI into silcincludes.h and silcwin32.h for

1285 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1287 * Fixed private message handling. It used some old code that
1288 caused the client to crash. Affecte file is
1289 lib/silcclient/client_prvmsg.c.
1291 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1293 * Added function silc_client_add_channel,
1294 silc_client_replace_channel_id, and removed functions
1295 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1296 from client library.
1298 * Added cross reference of the joined channels to the
1299 SilcClientEntry, and changed the SilcChannelEntry's
1300 users list to SilcHashTable. The affected files are
1301 lib/silcclient/idlist.[ch].
1303 * Fixed a bug in hash table tarversing. While the hash table
1304 is traversed with SilcHashTableList the table must not be
1305 rehashed. It is now guaranteed that auto rehashable tables
1306 are not rehashed while tarversing the list. Also defined that
1307 silc_hash_table_rehash must not be called while tarversing
1308 the table. Added function silc_hash_table_list_reset that must
1309 be called after the tarversing is over. The affected files are
1310 lib/silcutil/silchashtable.[ch].
1312 * Changed all hash table traversing to call the new
1313 silc_hash_table_list_reset in server and in client library.
1315 * Added function silc_client_on_channel to return the
1316 SilcChannelUser entry if the specified client entry is joined
1317 on the specified channel. This is exported to application as
1318 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1320 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1322 * Fixed founder regaining problem with JOIN command on normal
1323 server. The notify for mode change must be sent always and
1324 not only if !cmd->pending. Affected file silcd/command.c.
1326 * Fixed the WHOWAS command's reply sending to support the
1327 lists correctly. Affected file silcd/command.c.
1329 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1331 * When sending JOIN command to router for processing the
1332 sender's old command identifier was not saved back to the
1333 sender's command context, fixed now. The affected file is
1336 * Create the key in JOIN command of the router did not return
1337 the channel key, added check for this. Affected file is
1340 * Fixed a channel ID update bug in JOIN command reply. Do
1341 not directly upgrade the ID but call the function
1342 silc_idlist_replace_channel_id if the ID was changed.
1343 Affected file silcd/command_reply.c.
1345 * Fixed memory leaks from command calling if it would fail.
1346 Affected file silcd/command.c.
1348 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1350 * Applied patches from cras:
1352 Memory leak fixes around libaries, irssi window resize fix,
1353 new silclist.h and silcdlist.h, all extern inline changed to

1358 * Removed TRQ from lib/trq, not needed anymore.
1360 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1361 with server connections. Later this will be configurable
1362 in config file after new config file is done. Affected file
1365 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1367 * Fixed a crash in server related to channel announcements.
1368 Affected file silcd/server.c.
1370 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1372 * Fixed memory leaks in silc_server_create_new_channel*
1373 functions. Affected file silcd/server.c.
1375 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1376 which ID was changed. This way the router will send the
1377 user list for the channel again, and server won't be in
1378 desync in some rare circumstances. Affected file is
1379 silcd/packet_receive.c.
1381 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1383 * Check for NULL socket pointer in the function

1393 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1395 * Added lib/silcclient/client_ops_example.h as an template
1396 file for application programmers to quickly start using
1397 the SilcClientOperation functions in their application.
1398 Updated the lib/silcclient/README as well to tell about this
1399 nice file made available.
1401 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1403 * Call silc_server_remove_from_channels when removing client
1404 entry when NO_SUCH_CLIENT_ID was received. Affected file
1405 is silcd/command_reply.c.
1407 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1409 * Added server & router operator statistics updating. Affected
1410 file silcd/packet_receive.c and silcd/command.c.
1412 * Fixed the SERVER_SIGNOFF notify handling on normal server
1413 not to save the history information for clients. Same was
1414 fixed earlier in remove_clients_by_server function, but not
1415 here. Affected file silcd/packet_receive.c.
1417 * Raised the default connection-retry count from 4 to 7 in
1418 server. Affected file silcd/server.h.
1420 * Cancel any possible reconnect timeouts when we start the
1421 key exchange. Affected file silcd/server.c.
1423 * Do not reconnect on connection failure when SCONNECT was
1424 given. Affected files silcd/server.[ch].
1426 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1428 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1430 * Fixed the NICK command to always give the unformatted
1431 nickname to the one giving the NICK command. If unformatted
1432 nickname is cached already it will be formatted and the
1433 local entry will always get the unformatted nickname.
1434 Affected file lib/silcclient/idlist.c.
1436 * Fixed some double frees from client library commands.
1437 Affected file is lib/silcclient/command.c.
1439 * Fixed CUMODE command in server to assure that no one can
1440 change founder's mode than the founder itself, there was a
1441 little bug. Affected file silcd/command.c.
1443 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1445 * Removed the SilcClientCommandDestructor from the client
1446 libary, it is not needed anymore. Affected files are
1447 lib/silcclient/silcapi.h, command[_reply].[ch],
1448 client_notify, idlist.c.
1450 * Fixed GETKEY command to first resolve client, and then
1451 resolve the server only if the client was not found, instead
1452 of resolving both at the same time. Affected file is
1453 lib/silcclient/command.c.
1455 * Added silc_client_start_key_exchange_cb and lookup the
1456 remote hostname and IP address before starting the key
1457 exchange with server. The affected file is
1458 lib/silcclient/client.c.
1460 * The server's public key is now saved using the IP address
1461 of the server and not the servername for the filename.
1462 The hostname public key filename is checked as an fall back
1463 method if the IP address based filename is not found.
1465 Fixed the GETKEY command to save the fetched server key
1466 in correct filename.
1468 Print the remote server's hostname now when new key is
1469 received during connection process. Affected file is
1470 irssi/src/silc/core/client_ops.c.
1472 * Return always our own public key to the client if it asks
1473 for it with GETKEY command. Affected file silcd/command.c.
1475 * Removed the use_auto_addr variable from default config
1476 file since it was in wrong section. Affected file is
1479 * Fixed TOPIC_CHANGE notification to not route it when it
1480 was sent using silc_server_send_notify_to_channel function.
1481 Affected file silcd/command.c.
1483 * Fixed silc_server_send_notify_kicked to send the kicker's
1484 Client ID also, it was missing. Affected files are
1485 silcd/command.c, silcd/packet_send.[ch].
1487 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1489 * Do not save client history information in SERVER_SIGNOFF.
1490 Fixes the bug in normal server that it does not detect
1491 the client becoming valid after the server becomes back
1492 online. Affected file silcd/server_util.c.
1494 * Added `sock_error' field into the SilcSocketConnection
1495 context. When error occurs during socket operation (read
1496 or write) the error is saved. Added also new function
1497 silc_socket_get_error to return human readable socket error
1498 message. Affected files are lib/silcutil/silcsockconn.[ch],
1499 lib/silcutil/unix/silcunixsockconn.c, and
1500 lib/silcutil/win32/silcwin32sockconn.c.
1502 * The server now prints the socket error message in the
1503 signoff for client. Affected file silcd/server.c.
1505 * Fixed the `created' channel information sending from router
1506 to server in JOIN command. Checks now whether the channel
1507 really was created or not and set it according that.
1509 Fixed the JOIN command to use the client entry's current
1510 ID during the joining procedure instead of the one it sent
1511 in the command (it is checked though), since it can change
1512 between the packet processing and command processing, and
1513 would just case unnecessary pain in the client end. Affected
1514 file silcd/command.c.
1516 * Fixed a channel key payload sending to use correct channel
1517 ID when the server was forced to change the channel's ID by
1518 router. Router sent the key payload with the old Channel ID.
1519 Affected file silcd/packet_receive.c.
1521 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1523 * Call silc_server_save_channel_key only if the key payload
1524 was provided in the JOIN command's command reply. Affected
1525 file silcd/command_reply.c.
1527 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1529 * Fixed silc_mp_sizeinbase to return the value correctly with
1530 MPI. Affected file lib/silcmath/mp_mpi.c.
1532 * Fixed the stop_server signal to correctly stop the scheduler
1533 and gracefully stop the server when SIGTERM or SIGINT signals
1534 are received. Affected file silcd/silcd.c.
1536 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1538 * Simple handling of TERM and HUP signals. Also added some log
1539 flushing call around. Affected file is
1542 * Fixed small bugs in silclog.c. Now buffering output will take
1543 effect after 10 seconds since startup: This will ensure that
1544 no important startup messages are lost. Also output redirection
1545 will preserve original format ([Date] [Type] message).
1546 Affected file is lib/silcutil/silclog.c.
1548 * Added two options to the config file, in the logging section:
1549 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1550 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1552 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1554 * Do not print the warning about log files not being initialized
1555 more than once to avoid excess logging. Affected file is
1556 lib/silcutil/silclog.c.
1558 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1559 the SIM copying in make install in Makefile.am.pre.
1561 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1563 * Rewritten silclog APIs. Globally interesting changes follows:
1564 silc_log_set_files() changed to silc_log_set_file().
1565 silc_log_set_callbacks() changed to silc_log_set_callback().
1566 ROBOdoc documented silclog header file.
1567 SilcLogCb now returns bool to wether inihibit the default
1568 handler or not (to keep the old behaviour return always TRUE).
1569 The new APIs should also fix the problem of the
1570 silcd_error.log file that was written in the current directory.
1573 Log files streams will remain opened after silc_log_set_file()
1574 call, means less CPU usage notably on high traffic servers.
1575 File streams are now full buffered, and flushed to the disk
1576 every 5 minutes, lesses HD activity and CPU usage.
1577 Messages can be redirected, allowing admins to configure
1578 one single logfile for all server messages.
1579 the silc_log_quick global variable to activate fast-logging.
1580 Affected files lib/silcutil/silclog.[ch]
1582 * Changed some code to conform new silclog APIs. Affected
1583 files are doc/example_silcd.conf.in, silcd/server.c
1584 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1587 * Fixed a memory leak that could occur in some situations.
1588 Affected file silcd/serverconfig.c.
1590 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1592 * Added the silc_client_del_client to remove the client from
1593 all channels as well. Affected file lib/silcclient/idlist.c.
1595 * Fixed the client library to correctly remove the client
1596 from all channels when the client entry is being destroyed.
1597 Affected file lib/silcclient/client_notify.c, command.c.
1599 * Added auto-nicking support to the client library. If the
1600 applicatio now sets client->nickname it will be sent to the
1601 server after connecting by the library. This way for example
1602 SILCNICK (or IRCNICK) environment variables will have effect
1603 and always change the nickname automatically to whatever
1604 it is wanted. Affected file lib/silcclient/client.[ch].
1606 * Renamed silc_server_command_bad_chars to the
1607 silc_server_name_bad_chars and moved it to the
1608 silcd/server_util.[ch]. Added also new function
1609 silc_server_name_modify_bad to return nickname that
1610 includes bad characters as new nickname without those
1611 bad characters. This check and modify is now used in
1612 silc_server_new_client when the username is initially set
1613 as nickname, so it must be checked to be valid nickname.
1614 Affected file silcd/packet_receive.c.
1616 * The nickname length is now taken from the packet for real
1617 and not trusted to strlen() since it clearly can return
1618 wrong length for nickname including bad characters. This
1619 also applies to channel names. Affected file silcd/command.c.
1621 * Removed the lib/silcsilm/modules directory. Modules are now
1622 compiled into the lib/silcsim. Fixed the copying of the
1623 modules to follow symbolic links in Makefile.am.pre.
1625 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1627 * Fixed silc_string_regexify list creation. Fixes bugs with
1628 BAN and INVITE commands in server. The affected file is
1629 lib/silcutil/unix/silcunixutil.c.
1631 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1633 * Removed the command destructor entirely from the server's
1634 command and command reply routines. It is not needed, and
1635 its usage was buggy and caused crashes. Affected files are
1636 silcd/command[_reply].[ch].
1638 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * Cancel protocol and NULL sock->protocol if timeout
1641 occurred during protocol. Affected file silcd/server.c.
1643 * Cancel protocol timeouts always before calling the final
1644 callback, to assure that after final callback is called
1645 no other state will be called for the protocol anymore.
1646 Affected file silcd/protocol.c.
1648 * Print error log if incoming connection configuration could
1649 not be found. Affected file silcd/server.c.
1651 * Fixed JOIN command to correctly save the founder mode
1652 to the client on normal SILC server, when the channel
1653 was created by the router. Affected file silcd/command.c.
1655 * Fixed LIST command (hopefully) to send correct reply
1656 packets. Affected file silcd/command.c.
1658 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1660 * The silc_packet_receive_process now returns FALSE if the
1661 read data was invalid packet, and TRUE if it was ok.
1663 The server now checks that if unauthenticated connection
1664 sends data and its processing fails the server will close
1665 the connection since it could be a malicious flooder.
1667 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1669 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1671 * Make sure the warning about error opening a log file is
1672 printed only once and not everytime it fails (produces
1673 too much useless log). Affected file lib/silcutil/silclog.c.
1675 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1677 * Made the silc_server_daemonise() function more readable.
1678 Affected file silcd/server.c.
1680 * Pid file is now optional, the user may comment it out from
1681 the config file. Removed define SILC_SERVER_PID_FILE, we
1682 don't need a default any longer. Affected file
1683 configure.in.pre, lib/Makefile.am.pre.
1685 * Make some use of the pid file. The server now dies at startup
1686 if it detects a valid pid file on his path. The server would
1687 die anyway in this circumstance, because of the bind() failure.
1688 Affected file silcd/silcd.c.
1690 * No longer compiling lib/dotconf.
1692 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * Fixed JOIN command parsing not to crash. Affected file
1695 lib/silcclient/command.c.
1697 * Fied the NICK_CHANGE notify to add the new client entry
1698 even it is resolved. This removes an <[unknown]> nick
1699 thingy bug in the client. Affected file is
1700 lib/silcclient/client_notify.c.
1702 * Do not try to allocate 0 bytes (efence does not like it)
1703 in lib/silccore/silccomand.c when encoding payload.
1705 * Do not take IRCNICK as nickname in Irssi SILC client since
1706 it is not possible to set nickname before hand connecting
1707 the server (TODO has an entry about adding auto-nicking
1710 * Changed the silc_server_command_pending to check whether
1711 there already exists an pending entry with the specified
1712 command, command identifier and pending callback. This is
1713 to fix IDENTIFY and WHOIS related crashes that may register
1714 multiple pending commands with same identifier. Affected
1715 file silcd/command.c.
1717 * Fixed the server to reconnect to the router even if it
1718 was already reconnecting and EOF was received. This to
1719 fix a possibility that the server wouldn't ever try to
1720 auto-reconnect to the router. Affected file silcd/server.c.
1722 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Fixed the server's password authentication to use the
1725 length of the locally saved password, and not the one
1726 sent in the packet. Affected file silcd/protocol.c.
1728 * Fixed same password authentication problem in the
1729 Authentication Payload handling routines in
1730 lib/silccore/silcauth.c.
1732 * Yet another password authentication problem fixed with
1733 channel password handling in silcd/command.c.
1735 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * If first character of string in silc_parse_userfqdn is '@'
1738 then do not parse it. Affected file is
1739 lib/silcutil/silcutil.c.
1741 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1743 * Fixed minor bug in IDENTIFY command reply sending, which
1744 caused various weird problems during JOIN when it was
1745 resolving names for users. Affected file silcd/command.c.
1747 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1749 * Fixed the IDENTIFY command reply sending to chech better valid
1750 clients. It was possible to send incomplete list of replies.
1751 Affected file silcd/command.c.
1753 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Added silc_client_command[s]_[un]register functions now to
1756 dynamically register the commands in client library. Removed
1757 the static table of commands. This allows the client library
1758 to call commands without causing the application to know about
1759 what commands library has called.
1761 Removed the INFO command reply kludge to detect when the command
1762 was called by library. Now library use its own command reply
1763 function for INFO command.
1765 Added function silc_client_command_call to call a command.
1766 Application can use it to call command, not access the structure
1769 Now all commands that are sent by the client library (not
1770 explicitly sent by application) use own command reply functions.
1772 Affected files around lib/silcclient/ and in
1773 irssi/src/silc/core/.
1775 * Fixed the WHOIS command reply sending to chech better valid
1776 clients. It was possible to send incomplete list of replies.
1778 Fixed the WHOIS and IDENTIFY to send the request to router
1779 if normal server did not do it and did not find any results.
1781 Affected file silcd/command.c.
1783 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1785 * Moved the internal data from SilcClient context into its
1786 own file, not accesible to application. Affected files
1787 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1788 and other files in client library.
1790 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Added doc/examples installation target in Makefile.am.pre.
1795 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1797 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1798 commands the found client entry will be removed from the
1799 cache, after notifying application about the error. Affected
1800 file lib/silcclient/command_reply.c.
1802 * Changed the /MSG to check for exact nickname user gave, and
1803 not let `nick' match `nick@host' if it is only one found. Now,
1804 user must type the exact nickname (like nick@host2) even if
1805 there are no more than one same nicks found. This is to avoid
1806 a possibility of sending nickname to wrong nickname since
1807 `nick' could match `nick@host'. Affected file is
1808 irssi/src/core/silc-servers.c.
1810 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1812 * Do not print "you are now server operator" or similar when
1813 giving /away command. Affected files are
1814 irssi/src/silc/core/client_ops.c, silc-servers.h.
1816 * Made the silc_server_command_pending_error_check to send
1817 the same command reply payload it received back to the
1818 original sender of the command. This way all arguments
1819 that was received by the server will be received by the
1820 client too. Affected file silcd/command.c.
1822 * Added the silc_idcache_add to return the created cache entry
1823 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1825 * Add global clients to expire if they are not on any channel.
1826 This is because normal server will never know if they signoff
1827 if they are not on any channel. The cache expiry will take
1828 case of these entries. This is done by normal servers only.
1829 The affected files are silcd/command_reply.c,
1830 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1832 * If server receives invalid ID notification for WHOIS or
1833 IDENTIFY and the ID exists in the lists, it is removed.
1834 Affected file silcd/command_reply.c.
1836 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1837 in client then client entry that it matches is searched and
1838 the nickname is printed on the screen for user. Affected
1839 file irssi/src/silc/core/client_ops.c.
1841 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Use cache entry expire time in the LIST command reply to
1844 purge old entries from the cache after the LIST command
1845 reply has been received. This way we don't have non-existent
1846 entries in the cache for too long. Affected file is
1847 silcd/command_reply.c.
1849 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * If we are normal server, and we've not resolved client info
1852 in WHOIS or IDENTIFY from router, and it is global client,
1853 we'll check whether it is on some channel. If it is not
1854 then we cannot be sure about its validity and will resolve it
1855 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1856 file silcd/command.c.
1858 * Search channel by name (if possible) rather than by ID
1859 in IDENTIFY command's command reply. Affected file is
1860 silcd/command_reply.c.
1862 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1865 Updated specs and implemented it. Affected file silcd/command.c,
1866 silcd/packet_send.c and silcd/packet_receive.c.
1868 * Implemented the <founder auth> payload handling in the JOIN
1869 command. If provided all conditions for channel joining
1870 except requirement to provide correct passphrase can be
1871 overrided by the channel founder. Updated the protocol specs.
1872 Affected file silcd/command.c.
1874 Added support for founder auth in JOIN command in client
1875 library. Fixed the parsing of the JOIN command now to support
1876 all options as they should be. The affected file is
1877 lib/silcclient/command.c.
1879 * Optimized the WHOIS and IDENTIFY commands to send the request
1880 to router only if it includes nicknames or other names. If
1881 they include only IDs then check the local cache first before
1882 routing. Affected file is silcd/command.c.
1884 * Added channels topic announcements. Affected file is
1885 silcd/packet_receive.c and silcd/server.c.
1887 * Fixed the silc_server_send_notify_topic_set to really destine
1888 the packet to channel. Affected file silcd/packet_send.c.
1890 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1891 library. Affected file lib/silcclient/client_notify.c.
1893 * Added UMODE announcements. Affected file silcd/server.c.
1895 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1897 * Memory leak fixes in:
1899 lib/silcutil/silcsockconn.c
1900 lib/silcske/silcske.c
1901 lib/silcske/groups.c
1903 lib/silccrypt/silcpkcs.c
1904 lib/silccore/silccommand.c
1905 lib/silccore/silcidcache.c
1910 * ROBOdoc documented the lib/silcske/groups.h file and a
1911 bit changed the interface for better.
1913 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1915 * Update the client entry context in the ID cache after
1916 nick change. Affected file lib/silcclient/command.c.
1917 Fixes the CUMODE command when regaining founder privileges,
1918 and a little WHOIS problem.
1920 * Fixed silc_net_gethostbyname to correctly call the
1921 inet_ntop. Affected file lib/silcutil/silcnet.c.
1923 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1925 * Added IPv6 support checking to the configure.in.pre, added
1926 also --enable-ipv6 option to override the check. Affected
1927 file configure.in.pre.
1929 * The silc_thread_create now calls the start function
1930 directly if threads support is not compiled in. Removes
1931 ugly #ifdef's from generic code. Affected files are
1932 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1934 * Added silc_net_gethostby[name/addr]_async to asynchronously
1935 resolve. Affected files are lib/silcutil/silcnet.[ch].
1937 * Added support for rendering IPv6 based server, client and
1938 channel IDs. Affected file lib/silcutil/silcutil.c.
1940 * Added support for creating IPv6 based server IDs. Affected
1941 file is silcd/serverid.c.
1943 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1945 * Added silc_net_gethostby[addr/name] into the
1946 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1947 routines. Added silc_net_is_ip[4/6]. Affected file is
1948 lib/silcutil/unix/silcunixnet.c. All routines that take
1949 address as argument now supports both IPv4 and IPv6 addresses.
1951 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1953 * Fixed LIST command reply sending in server. Affected file
1956 * Server now sends the kicker's client ID in the KICK notify
1957 to the kicked client. Affected file silcd/command.c.
1959 * The client library now parses the kickers client ID and
1960 UI displays it. Affected files lib/silcclient/client_notify.c
1961 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1963 * Made all payload parsing function prototypes consistent.
1964 They all take now const unsigned char * and uint32 pair as
1965 the payload data instead of SilcBuffer. Changes all around
1966 the source tree. Other unsigned char* -> const unsigned char*
1967 changes around the tree as well.
1969 * Optimized SFTP client and server packet sending not to
1970 allocate new buffer for each packet but to recycle the
1971 first allocated buffer. Affected files are
1972 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1974 * Optimized the SFTP client to use SilcList instead of
1975 SilcDList for requests, because it is faster. Affected file
1976 is lib/silcsftp/sftp_client.c.
1978 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1979 into lib/silccore/silcid.[ch].
1981 Renamed silcpayload.[ch] into silcargument.[ch].
1983 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * If client entry is deleted with active key agreement
1986 session, abort the session.
1988 The silc_client_abort_key_agreement now calls the completion
1989 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1991 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1994 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1996 * Don't use __restrict in older GCC's. Affected file is
1997 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1999 * silc_net_localhost now attempts to reverse lookup the
2000 IP/hostname. Affected file lib/silcutil/silcnet.c.
2002 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2003 command. It can be used to gain founder privileges at
2004 the same time when joining the channel.
2006 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2007 kicker's client ID as well. Updated protocol specs.
2009 Defined that the server must send SILC_COMMAND_IDENTIFY
2010 command reply with error status to client who sent
2011 private message with invalid client ID.
2013 Updated the protocol specification.
2015 * Added silc_server_send_command_reply to send any
2016 command reply. Affected file silcd/packet_send.[ch].
2018 * Added silc_id_payload_encode_data to encode ID payload
2019 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2021 * The server now send IDENTIFY command reply with error
2022 status if client ID in private message is invalid. Affected
2023 file silcd/packet_receive.c.
2025 * Save the server key file with server's IP address in
2026 the filename instead of hostname. The affected file is
2027 irssi/src/silc/core/client_ops.c.
2029 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2034 * Added libtool support for compiling shared objects in
2035 lib/silcsim. Affected file configure.in.pre and
2036 lib/silcsim/Makefile.am. Original patch by cras.
2038 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Pid file configuration, and server's config file fixes
2041 patch by toma. Updated CREDITS file.
2043 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Fixed silc_client_channel_message to not try to decrypt
2046 the message twice if it resolved the destination client
2047 information. This could cause of dropping one channel
2048 message. Affected file lib/silcclient/client_channel.c.
2050 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2052 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2053 lib/silcclient/client.c. This function is used when the SILC
2054 Client is run under some other scheduler, or event loop or
2055 main loop. On GUI applications, for example this may be
2056 desired to used to run the client under the GUI application's
2057 main loop. Typically the GUI application would register an
2058 idle task that calls this function multiple times in a second
2059 to quickly process the SILC specific data.
2061 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2063 * Fixed silc_server_drop() for dropping the supplementary
2064 groups as well, this could cause a security hole on some
2067 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2069 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2072 * Write PID file after dropping privileges. Added -F option
2073 to run server on foreground. A patch by debolaz.
2074 Affected files silcd/server.c, silcd/silcd.c.
2076 * Fixed MOTD to return the MOTD file server name. Affected
2077 file silcd/command.c.
2079 * Added INFO command reply handling to the Irssi SILC Client.
2080 Affected file irssi/src/silc/core/client_ops.c.
2082 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Fixed the silc_idcache_list_* routines to really support
2085 the dynamic list. Fixes a crash. Affected file is
2086 lib/silccore/silcidcache.c.
2088 * Fixed the LIST command reply to really call LIST command's
2089 pending callbacks. Affected file silcd/command_reply.c.
2091 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2093 * Update conn->local_entry->nickname after giving NICK
2094 command. Affected file lib/silcclient/command.c.

2098 * Added the [pid] option to the silcd configuration file
2100 Affected files: serverconfig.[ch] and silcd.c
2102 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2104 * Save fingerprint in WHOIS command reply in server.
2105 Affected file silcd/command_reply.c.
2107 * Fixed NICK commands pending callback registration.
2108 Affected file lib/silcclient/command.c.
2110 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Use ++server->cmd_ident when sending commands in server,
2113 instead of random number. Affected file silcd/command.c.
2115 * Fixed GETKEY command reply to call actually GETKEY pending
2116 command callbacks. Affected file silcd/command_reply.c.
2118 * A bit stricter check for nicknames. Check for same nickname
2119 in NICK command also. Affected file silcd/command.c.
2121 * Do not call INFO command everytime client ID changes, only
2122 during first connecting. Affected file lib/silcclient/client.c.
2124 * Set the new nickname only after successful command reply for
2125 NICK command is returned by server. Affected file
2126 lib/silcclient/command.c.
2128 * Remove nicknames from nicklist during server_signoff notify.
2129 Should fix /NAMES bit more. The affected file is
2130 irssi/src/silc/core/silc-channels.c.
2132 * Added `fingerprint' field to the SilcIDListData in the
2133 silcd/idlist.h to hold the fingerprint of the client's
2136 Send the fingerprint of the client's public key in WHOIS
2139 Affected files silcd/command.c, and silcd/idlist.[ch].
2141 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2142 create fingerprint from given data.
2144 * Show the fingerprint of the client's public key in WHOIS.
2145 Affected files irssi/src/module-formats.[ch] and
2146 irssi/src/silc/core/client_ops.c.
2148 * Format the multiple same nicknames also during JOIN and
2149 NICK_CHANGE notifys. Affected file is
2150 lib/silcclient/client_notify.c.
2152 * Do not print error on screen for invalid private message
2153 payload since it can come if someone is sending private
2154 messages with wrong key. Affected file
2155 lib/silccore/silcprivate.c.
2157 * Fixed multiple concurrent /PING crash. Affected file
2158 lib/silcclient/command.c.
2160 * Changed the wrong ID encoding. All IP addresses must be
2161 in MSB first order in encoded format. They were encoded
2162 wrong and was in LSB format. Affected files are
2163 silcd/serverid.c, lib/silcutil/silcutil.c.
2165 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2167 * Call the `connect' client operation through the scheduler
2168 in case of error. Affected file lib/silcclient/client.c.
2170 * Call the `failure' client operation even if the error
2171 occurred locally during a protocol. Affected file is
2172 lib/silcclient/protocol.c.
2174 * Added support of sending LIST command to router from normal
2175 server. This way normal server can get list of all channels
2176 in the network too. Fixed the channel list sending in the
2177 server too. Affected files are silcd/command.c, and
2178 silcd/command_reply.[ch].
2180 * Added silc_server_update_channels_by_server and
2181 silc_server_remove_channels_by_server. They are used during
2182 disconnection of primary router and in backup router protocol.
2183 Affected file silcd/server_util.[ch], silcd/server.c and
2184 silcd/server_backup.c.
2186 * Fixed channel adding to global list in IDENTIFY command
2187 reply in server. Affected file silcd/command_reply.c.
2189 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2191 * If the incoming packet type is REKEY or REKEY_DONE process
2192 that packet always synchronously. Fixes yet another MAC
2193 failed error on slow (dialup) connections. Affected file
2194 lib/silcclient/client.c and silcd/server.c.
2196 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2198 * Call check_version SKE callback for initiator too. Affected
2199 file lib/silcske/silcske.c.
2201 * Implemented fix for security hole found in the SKE that was
2202 fixed in the specification few days back; the initiator's
2203 public key is now added to the HASH value computation.
2204 Added backwards support for the old way of doing it too, for
2205 old clients and old servers. Affected file is
2206 lib/silcske/silcske.c.
2208 * Enabled mutual authentication by default in SKE. If initiator
2209 is not providing mutual authentication the responder will
2210 force it. This will provide the proof of posession of the
2211 private key for responder. The affected files are
2212 lib/silcclient/protocol.c and silcd/protocol.c.
2214 * Do not cache anymore the server's public key during SKE.
2215 We do mutual authentication so the proof of posession of
2216 private key is done, and if the server is authenticated in
2217 conn auth protocol with public key we must have the public
2218 key already. Affected file silcd/protocol.c.
2220 * Added new global debug variable: silc_debug_hexdump. If
2221 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2222 file lib/silcutil/silclog.[ch].
2224 * Fixed compilation warning due to char * -> const char *.
2225 Affected files lib/silcutil/silcnet.h, and
2226 lib/silccore/silcauth.[ch].
2228 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * Fixed CMODE command when new channel key was created. If
2231 the creation failed the old key was removed. Next time giving
2232 same command would crash the server since the old key was
2233 freed already. Affected file silcd/command.c.
2235 * Fixed the silc_server_announce_get_channels to not crash
2236 on reconnect. Affected file silcd/server.c.
2238 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Added silc_log_set_debug_string function to set a regex
2241 string to match for debug output. Only the function names,
2242 or filenames matching the given debug string is actually
2243 printed. This way it is possible to filter out those debug
2244 strings that user is not interested in.
2246 Fixed a bug in silc_string_regexify.
2248 Affected files lib/silcutil/silclog.[ch], and
2249 lib/silcutil/unix/silcunixutil.c.
2251 * Changed the -d options in both server and Irssi SILC client
2252 to take the debug string as argument. Affected files
2253 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2255 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * Added silc_hash_babbleprint to create a Bubble Babble
2258 Encoded fingerprint. The encoding is developed by Antti
2259 Huima (draft-huima-babble-01.txt), and it creates human
2260 readable strings out of binary data. Affected file
2261 lib/silccrypt/silchash.[ch].
2263 * Print the babble print now in addition of fingerprint as well
2264 in Irssi SILC client. Affected files are
2265 irssi/src/fe-common/silc/module-formats.[ch],
2266 irssi/src/fe-common/silc/core/client_ops.c.
2268 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2270 * Fixed a security problem found in SKE. The initiator's
2271 public key too is now added to the HASH hash value creation
2272 which is signed by the responder to create the SIGN value.
2273 This will prevent anyone in the middle to lie to the responder
2274 about the initiator's public key. If this is done now, the
2275 man in the middle will get caught. Updated the protocol
2278 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * Better installation directory handling. Configure module
2281 paths and other paths automatically to example_silc* files
2282 in doc/. A patch by toma.
2284 * Fixed compiler warning from MPI library, and from SILC RNG.
2287 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2288 It can be configured with ./configure. A patch by toma.
2290 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2292 * Find correct make to use in prepare-clean. A patch by
2293 toma. Affected file prepare-clean.
2295 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2297 * Added irssi variables use_auto_addr, auto_bind_ip,
2298 auto_bind_port and auto_public_ip.
2300 * Changed the interface for silc_client_send_key_agreement
2301 in lib/silcclient/silcapi.h
2305 irssi/src/silc/core/silc-core.c
2307 lib/silcclient/silcapi.h
2308 irssi/src/silc/core/silc-channels.c
2309 lib/silcclient/client_keyagr.c
2312 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Added silc_pkcs_public_key_compare to compare two
2315 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2317 * Check that the client who set the founder mode on the
2318 channel is the same client that is giving the founder
2319 mode to itself. It is done by comparing the saved public
2320 key (it is saved even in the authentication is passphrase).
2321 Affected file silcd/command.c.
2323 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Do not process packet for disconnected socket connection.
2326 Affected file lib/silccore/silcpacket.c.
2328 * Process the DISCONNECT packet through scheduler in the
2329 client library. Affected file lib/silcclient/client.c.
2331 * Fixed the silc_client_packet_parse to not to increase
2332 the packet sequence number if the conn->sock and the
2333 current socket connection is not same. This can happen
2334 for example during key agreement when the conn includes
2335 multiple socket connections (listeners). Affected file
2336 lib/silcclient/client.c.
2338 * The sender of the file transfer request now provides also
2339 the pointer (listener) for the key exchange protocol. If
2340 the listener cannot be created then it sends empty key
2341 agreement and lets the receiver provide the listener.
2343 Added `local_ip' and `local_port' arguments to the
2344 silc_client_file_send. If they are provided they are used,
2345 if not then it will attempt to find local IP address, if
2346 not found or bind fails then the remote client will provide
2349 Affected files are lib/silcclient/client_ftp.c and
2350 lib/silcclient/silcapi.h.
2352 * Extended the FILE SEND command to support defining the
2353 local IP and port for key exchange listener. They are
2354 optional. Affected file irssi/src/silc/core/silc-servers.c.
2356 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2358 * Defined to WHOIS command reply the sending of fingerprint
2359 of the client's public key (if the proof of posession of the
2360 corresponding private key is verified by the server).
2361 Updated to the protocol specification.
2363 * Added support of receiving the client's public key's
2364 fingerprint in command reply in client library. Affected
2365 file is lib/silcclient/command_reply.c, and
2366 lib/silcclient/idlist.[ch].
2368 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2370 * Do not send over 128 chars long nickname to the server
2371 in NICK command. Affected file lib/silcclient/command.c.
2373 * Do not send over 256 chars long channel names to the server
2374 in JOIN command. Affected file lib/silcclient/command.c.
2376 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2378 * Assure that silc_server_close_connection cannot be called
2379 twice for same socket context. Affected file is
2382 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Send error message to application if opening file for
2385 writing during file transfer fails. Affected file is
2386 lib/silcclient/client_ftp.c.
2388 Remove all file transfer sessions for a client that we're
2389 removing from ID cache.
2391 Affected file is lib/silcclient/client_ftp.c.
2393 * Fixed silc_net_addr2bin to return correct address. Affected
2394 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2396 * Fixed file transfer session removing on signoff notify.
2397 Affected file irssi/src/silc/core/silc-servers.c.
2399 * Added the SilcClientFileError to be returned in the monitor
2400 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2401 Affected file lib/silcclient/silcapi.h.
2403 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Fixed a crash in silc_client_ftp_free_sessions and
2406 silc_client_ftp_session_free_client. Affected file
2407 lib/silcclient/client_ftp.c.
2409 * Added `disabled' field in the SilcChannelEntry in the server
2410 to indicate if the server entry is disabled. Affected file
2411 silcd/idlist.h, silcd/command[_reply].c.

2420 * Fixed a crash in client resolving in client_prvmsg.c in
2421 client library. Affected file lib/silcclient/client_prvmsg.c.
2423 * Do not actually remove the client directly from ID cache
2424 during SERVER_SIGNOFF, but invalidate it. This way we
2425 preserve the WHOWAS info for the client. Affected file
2426 silcd/server_util.c.
2428 * Fixed SERVER_SIGNOFF notify handling in the server. The
2429 server is now able to process incoming SERVER_SIGNOFF notify
2430 for a server that it doesn't even know about. It will remove
2431 the clients provided in the notify. Affected file
2432 silcd/packet_receive.c.
2434 * Check for partial packet in data queue after every packet that
2435 was found from the queue. Return and wait for more data if
2436 there is partial data in queue. Affected file is
2437 lib/silccore/silcpacket.c.
2439 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2442 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2443 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2444 Affected files lib/silcclient/silcapi.h and
2445 lib/silcclient/client_ftp.c.
2447 * Check that newsize in silc_buffer_realloc is larger than
2448 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2450 * Added better monitor of file transfers. It now monitors
2451 key agreement protocol during the file transfer too. Added
2452 error reporting too. Affected files
2453 irssi/src/silc/core/silc-servers.c,
2454 irssi/src/fe-common/silc/module-formats.[ch].
2456 * Wrote a help file for FILE command.
2458 * Added silc_rng_global_get_byte_fast to get not-so-secure
2459 random data as fast as possible. Random data is read from
2460 /dev/urandom if available and from the SILC RNG if not
2461 available. It is used in padding generation. Affected file
2462 lib/silccrypt/silcrng.[ch].
2464 * All packets in client library are now processed synchronously.
2465 Optimized packet processing a lot. Affected file
2466 lib/silcclient/client.c.
2468 * All server connection packets are processing synchronously
2469 now in server, to optimize packet processing. Affected file
2472 * Include files are installed now only in Toolkit distribution
2473 if make install is given. Affected files: all Makefile.am's.
2475 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Assure that silc_client_notify_by_server_resolve does not
2478 resolve the client information multiple times. If it cannot
2479 be found by the first it cannot be found at all. Affected
2480 file lib/silcclient/client_notify.c.
2482 * Fixed WHOWAS command reply calling. Affected file
2483 lib/silcclient/command_reply.c.
2485 * Removed all references to silc_idlist_get_client from the
2486 Irssi SILC client since that call is internal call used by
2487 the library. The Irssi SILC client will use now client
2488 retrieval functions found in silcapi.h.
2490 * Fixed a bug in resolving nickname info before sending
2491 private message. It used freed memory. Affected file
2492 irssi/src/silc/core/silc-servers.c.
2494 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Assure my_channels statistics cannot go negative in server.
2497 Affected files silcd/server.c, silcd/server_util.c.
2499 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2509 lib/sftp/sftp_fs_memory.c.
2511 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2513 * Added silc_net_localip to return local host's IP address.
2514 Affected file lib/silcutil/silcnet.[ch].
2516 * If key exchange or rekey protocol is active for a connection
2517 parse all packets syncronously since there might be packets
2518 in packet queue that we are not able to process without first
2519 processing packets before them. Affected file silcd/server,
2520 lib/silcclient/client.c.
2522 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2523 whether library should continue processing the packet.
2524 Affected file lib/silccore/silcpacket.h.
2526 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2527 SilcSFTPMonitorData to SFTP server to monitor various
2528 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

2536 transmission. Affected file lib/silcclient/client_ftp.c,
2537 lib/silccilent/client.[ch].
2539 * Added new local command FILE to the Irssi SILC Client.
2540 It is used to perform the file transfer. It has subcommands
2541 SEND, RECEIVE, SHOW and CLOSE. Affected files
2542 irssi/src/silc/core/client_ops.c,
2543 irssi/src/silc/core/silc-server.[ch].
2545 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Relay the SILC_PACKET_FTP in the server. Affected files

2552 * Renamed silc_file_read and silc_file_write to functions
2553 silc_file_readfile and silc_file_writefile. Added function
2554 silc_file_open and silc_file_close. Affected files
2555 lib/silcutil/silcutil.[ch].
2557 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2559 * Resolve the client info when received private message or
2560 channel message for a client which nickname we don't know.
2561 Affected files lib/silcclient/client_prvmsg.c and
2562 lib/silcclient/client_channel.c.

2570 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2571 is incomplete and is being resolved, it won't be resolved
2574 Make sure also that USERS command reply does not resolve
2575 twice information. Affected file is
2576 lib/silcclient/command_reply.c.
2578 Make sure that silc_client_get_clients_by_list does not
2579 resolve twice same information.
2581 * Check for valid client->id in the silc_server_free_client_data.
2582 Affected file silcd/server.c.
2584 * Fixed /GETKEY nick@server not to crash if the server entry
2585 is not found. Affected file lib/silcclient/command.c.
2587 * Fixed the silc_server_check_cmode_rights to check the
2588 requested modes correctly. Affected file silcd/command.c.
2590 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Better checks for non-printable chars in nick added.
2593 Affected file silcd/command.c.
2595 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2597 * Call the silc_server_udpate_servers_by_server in the
2598 primary router that comes back online in the backup resuming
2599 protocol. Otherwise it routes packets wrong. Affected file
2600 silcd/server_util.[ch], silcd/server_backup.c.
2602 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2604 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2605 lib/silcutil/silcbuffmt.[ch].
2607 * Redefined the SILC packet header to include the padding
2608 length. Affected file lib/silccore/silcpacket.[ch].
2610 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2611 length for maximum padding up to 128 bytes). Affected
2612 file lib/silccore/silcpacket.h.
2614 * Removed all backwards support for old 0.5.x MAC thingies.
2615 The SILC packet header change makes it impossible to be
2616 backwards compatible.
2618 * Send the ENDING packet with timeout in the backup resuming
2619 protocol. This is to assure that all routers has connected
2620 to the primary router. Affected file silcd/server_backup.c.
2622 * Changed the RNG to take the first IV from random data. It
2623 used to take it from zero actually. Changed the RNG also
2624 to use /dev/urandom during session. /dev/random is used
2625 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2627 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Changed the SILC packet header to have the first two bytes
2630 (the packet length) encrypted. Affected files aroung the
2631 code tree, lib/silccore/silcpacket.[ch]. Removed the
2632 SilcPacketCheckDecrypt callback. It is not needed anymore
2633 since the silc_packet_receive_process will determine now
2634 whether the packet is normal or special.
2636 * Implemented the unidirectional MAC keys. Affected files
2637 lib/silcske/silcske.c, silcd/protocol.c and
2638 lib/silcclient/protocol.c.
2640 * Implemented the packet sequence number to the MAC computation.
2641 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2642 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2643 lib/silcclient/protocol.c.
2645 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * Allow backup router to announce servers. All servers
2648 announced by backup router are added to the global list
2649 automatically. Update hte server's socket to our primary
2650 router also when backup router announces a server.
2651 Affected file silcd/packet_receive.c.
2653 * Do not update the client->router in the function
2654 silc_server_udpate_clients_by_server if the client is on
2655 global list. We might fail to find any specific server
2656 for locally connected clients and local cell clients. They
2657 should still use the `from' and not `to' as client->router.
2658 This fixes backup router resuming protocol. Affected file
2659 silcd/server_util.c.
2661 * Decrease channel statistics count only if the channel
2662 deletion worked. Affected files are silcd/server.c and
2663 silcd/server_util.c.
2665 * Added silc_server_update_servers_by_server to update origin
2666 of all server entries. Used during backup router protocol.
2667 Affected files silcd/server_util.[ch], silcd/server.c. and
2668 silcd/backup_router.c.
2670 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2671 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2672 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2673 lib/silccrypt/silchmac.c.
2675 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2677 * Assure that router cannot reroute the same channel message
2678 to the sender. Affected file silcd/packet_receive.c.
2680 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Made better checks that the channel message is not sent
2683 to the router it came from. Affected file is
2684 silcd/packet_send.c. Fixed memory leak too.
2686 * Announce informations for incoming router connection, but
2687 only after checking if it is replaced by backup router.
2688 Affected file silcd/packet_receive.c.
2690 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2692 * Fixed the backup resuming protocol to work in multiple
2693 router environment. Affected file silcd/server_backup.c.
2695 * Route packet only to one router in the function
2696 silc_server_packet_send_to_channel. Affected file is
2697 silcd/packet_send.c.
2699 * Fixed silc_server_send_notify_dest to set the broadcast
2700 flag. Fixed the silc_server_send_notify_topic to actually
2701 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2702 Affected file silcd/packet_send.c.
2704 * Changed the SFTP Filesystem interface. Changed the
2705 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2706 the filesystem operation function. The SilcSFTPFilesystem
2707 is now a context that is allocated by all filesystem allocation
2708 functions and it already includes the operations structure
2709 and filesystem specific context. It is given as argument
2710 now to the silc_sftp_server_start. This made the interface
2711 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2712 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2714 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2716 * Changed the backup router adding and getting interfaces
2717 in the server. The router that will be replaced by the
2718 specified backup router is now sent as argument. Affected
2719 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2722 * Added silc_net_addr2bin_ne to return the binary form of
2723 the IP address in network byte order. Affected files
2724 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2726 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2728 * Check for existing server ID in silc_server_new_server
2729 and in silc_server_connect_to_router_final and remove the
2730 old entry if it exists. Affected file silcd/packet_receive.c,
2733 * Send the channel message always to only one router, either
2734 in upstream or downstream. Affected file is
2735 silcd/packet_send.c.
2737 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2739 * Wrote the definition of the backup resuming protocol to the
2740 protocol specification.
2742 * Removed one redundant channel key generation from normal
2743 server during joining procedure. Removed one redundant
2744 channel key sending from server to router during joining
2745 procedure. Affected file silcd/command.c.
2747 * Made minor bugfixes to the backup router resuming protocol.
2748 Affected file silcd/server_backup.c, server.c.
2750 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2752 * Added --disable-asm configuration option. Affected files
2753 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2756 * Implemented the backup resuming protocol that is used to
2757 resume the primary router position in the cell after the
2758 primary router comes back online. Affected files
2759 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2760 and silcd/server_util.[ch].
2762 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2764 * Sleep two (2) seconds after sending QUIT command to server.
2765 Affected file lib/silcclient/command.c.
2767 * Assure that if outgoing data buffer is pending do not force
2768 send any data. Affected file silcd/packet_send.c.
2770 * Assure that if outgoing data buffer is pending do not force
2771 send any data. Affected file lib/silcclient/client.c.
2773 * Implemented the backup router support when the primary router
2774 goes down. The servers and routers can now use the backup
2775 router as new primary router without loosing connectivity.
2777 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2780 in the server to indicate disabled entry. All data read
2781 from the connection will be ignored and no data is sent
2782 for entry that is disabled. Affected files are
2783 silcd/idlist.h, silcd/server.c.
2785 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Created SFTP client and server test programs in the
2788 lib/silcsftp/tests directory.
2790 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2792 * Implemented memory filesystem (virtual filesystem) for
2793 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2796 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2798 * Implemented the SFTP (SSH File Transfer Protocol) to the
2799 lib/silcsftp. It includes SFTP client and SFTP server
2802 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2804 * Moved lib/silccore/silcprotocol.[ch] to the
2805 lib/silcutil library.
2807 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2808 take variable argument list pointer as argument. Affected
2809 file lib/silcutil/silcbuffmt.[ch].
2811 * Added silc_buffer_set function that is used to set data
2812 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2813 Affected file lib/silcutil/silcbuffer.h.
2815 * Changed various routines in the core library to use the new
2816 silc_buffer_set instead of allocating new buffer only for
2819 * Added 64-bit value formatting and unformatting support to the
2820 silc_buffer_[un]format routines. Affected file is
2821 lib/silcutil/silcbuffmt.[ch].
2823 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2824 to includes/bitmove.h.
2826 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2828 * Fixed channel user mode saving in client library. Affected
2829 file lib/silcclient/command[_reply].c.
2831 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * Defined the file transfer to the SILC Protocol. Added
2834 new packet type SILC_PACKET_FTP and defined File Transfer
2835 Payload. The mandatory file transfer protocol is SFTP
2836 (SSH File Transfer Protocol). Affected file in addition
2837 of the internet draft is lib/silccore/silcpacket.h.
2839 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2840 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2841 is used as part of backup router protocol when the primary
2842 router of the cell is back online and wishes to resume
2843 the position as primary router.
2845 * Redefined the MAC generation keys in the protocol. The
2846 same key is not used anymore in both direction. Both
2847 direction will now use different keys for sending and
2848 receiving. This fixes a potential security flaw. This
2849 change causes incompatibilities in the protocol.
2851 * Redefined also the MAC computation from the packet.
2852 An packet sequence number is now added to the MAC
2853 computation. This prevents possible replay attacks against
2854 the protocol. This change too causes incompatibilities
2857 Added `sequence' field to the SilcPacketContext to hold
2858 the current sequence number for the packet.
2860 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2862 * Added `created' field to the SilcIDListData in the file
2863 silcd/idlist.h to indicate the time when the entry was
2866 * Added `created' field to the SilcChannelEntry too. Affected
2867 file silcd/idlist.h.
2869 * Added `creation_time' aguments to all the announcement functions
2870 in the server. If it is provided then only the entries that
2871 was created after the provided time frame are actually
2872 announced. Affected file silcd/server.[ch].
2874 * The protocol says that the Channel ID's IP address must be
2875 based on the router's IP address. Added check for this in
2876 the silc_server_new_channel when processing incoming New Channel
2877 Payload. Affected file silcd/packet_receive.c.
2879 * Print out the correct version with --version in SILC client.
2880 Affected file irssi/src/silc/core/silc-core.c.
2882 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2884 * Fixed WHOWAS command to check for completnes of the client
2885 entry always, not just when the command is coming from client.
2886 Affected file silcd/command.c.
2888 * Added new function silc_server_packet_queue_purge to purge the
2889 outgoing data queue to the network. After the function returns
2890 it is guaranteed that the outgoing packet queue is empty.
2891 Affected file silcd/packet_send.[ch].
2893 * Purge the outgoing packet queue in the rekey protocol's final
2894 callback to assure that all rekey packets go to the network
2895 before quitting the protocol. Affected file silcd/server.c.
2897 * Added silc_client_packet_queue_parse as similar function as
2898 in server to the client library. The affected file is
2899 lib/silcclient/client.c.
2901 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Splitted silcd/server.c and created silcd/server_util.[ch]
2904 for utility functions.
2906 * Added new socket flag SILC_SF_DISABLED to indicate that the
2907 connection is open but nothing can be sent to or received from
2908 the connection. Affected file lib/silcutil/silsockconn.[ch].
2909 The checking for disabled socket is checked in the low level
2910 silc_socket_write and silc_socket_read functions.
2912 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2914 * Allow only nicknames and channel names that fits into the
2915 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2917 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2919 * When processing JOIN command reply in server check that if
2920 the channel exists in our global list we'll move it the local
2921 list. Affected file silcd/command_reply.c.
2923 * Fixed the check whether client is joined on the channel already
2924 in JOIN command. Affected file lib/silcclient/command.c.
2926 * Fixed the JOIN command reply to check whether the channel
2927 already exists. Affected file lib/silcclient/command_reply.c.
2929 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Added silc_ske_status_string to map the SKE error numbers
2932 to readable strings. The affected files are
2933 lib/silcske/silcske[_status].[ch].
2935 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Do not show the private channels on the WHOIS channel list
2938 as it is not allowed by the protocol. The affected file is
2941 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2943 * Assure that the packet length digged from the actual packet
2944 is something sensible in the silc_packet_decrypt_rest_special
2945 in lib/silccrypt/silcpacket.c.
2947 * Free and NULL the allocated pointer in silc_hmac_alloc if
2948 the HMAC allocation fails. The affected file is
2949 lib/silccrypt/silchmac.c.
2951 * Print the selected security properties to the log files in
2952 the server. Affected file silcd/protocol.c.
2954 * Add SKE's reference counter even if calling the completion
2955 callback manually. Otherwise it goes negative, although it
2956 does not cause any problems. The affected file is
2957 lib/silcske/silcske.c.
2959 * Remove the client entry with short timeout after giving the
2960 KILL command. Affected file lib/silcclient/command.c.
2962 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2963 case all found clients are already disconnected (WHOWAS would
2964 found them) in the server. Affected file silcd/command.c.
2966 * Update the last_receive (time of last data received) to be
2967 updated only when received private or channel message so that
2968 the idle time showed in WHOIS makes more sense.
2970 * Added boolean field `valid' in to the SilcClientEntry in the
2971 client library to indicate whether the entry is valid or not.
2972 This fixes the nickname change bug on channel when changing
2973 the nickname to be same than the old (like nick to Nick) the
2974 nickname formatter doesn't set the new nick anymore to Nick@host.
2975 Affected file lib/silcclient/idlist.[ch].
2977 * Now actually fixed the nickname changing on disconnection.
2978 Added new function silc_change_nick to the Irssi SILC Client.
2979 Affected file irssi/src/silc/core/client_ops.c,
2980 irssi/src/silc/core/silc-nicklist.[ch].
2982 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2984 * Check that the public key exists in the GETKEY command before
2985 trying to encode it. Affected file silcd/command.c.
2987 * Print some notifications on received public keys with GETKEY
2988 command in the Irssi SILC Client. Affected files are
2989 irssi/src/fe-common/silc/module-formats.[ch],
2990 irssi/src/silc/core/client_ops.c.
2992 * Use IDENTIFY command to resolve the server information in the
2993 GETKEY command instead of INFO command. Affected file
2994 lib/silcclient/command.c.
2996 * All command reply functions in the client library now calls
2997 the pending command reply callbacks even if an error has
2998 occurred. The server has done this a long time and now it was
2999 time to move the client library to this as well. Now all
3000 errors can be delivered back to the pending command reply
3001 callbacks if necessary. Affected files are
3002 lib/silcclient/command[_reply].[ch].
3004 * Change the nickname on disconnection back to the username
3005 because in reconnect the server will enforce it to it anyway.
3006 Affected file irssi/src/silc/core/silc-servers.c.
3008 * Fixed a config file parsing bug in the Irssi SILC client.
3009 Affected file irssi/src/silc/core/clientconfig.c.
3011 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * When printing the channel mode on JOIN, verify that the
3014 channel key and channel's HMAC are valid. Affected file
3015 irssi/src/silc/core/client_ops.c.
3017 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3020 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3021 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3023 * Removed channel key rekey task deleting from the function
3024 silc_server_save_channel_key. Affected file silcd/server.c.
3025 Added explicit timeout task context instead that is used to
3026 delete the task if we are registering a new task before the
3027 new task has elapsed.
3029 * When channel key rekey occurs the client library now saves
3030 the old channel key for a short period of time (10 seconds) and
3031 is able to use it in case some is still sending channel
3032 messages encrypted with the old key after the rekey. Affected
3033 file lib/silcclient/[idlist.h|client_channel.c].
3035 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3037 * Added check to the silc_server_new_id_real to not accept
3038 new ID if it is the sender's own ID. Affected file is
3039 silcd/packet_receive.c.
3041 * Assure that we do not announce ourself or the one we've
3042 sending our announcements when we're router and are announcing
3043 servers to our primary router. Affected file silcd/server.c.
3045 * Fixed silc_server_command_identify_check_client to assemble
3046 correct WHOIS packet. It send corrupted WHOIS packet and
3047 caused problem with router to router connections. Affected
3048 file silcd/command.c.
3050 Fixed also silc_server_command_whois_check the same way
3051 as for the IDENTIFY command.
3053 * Added new SilcIDListStatus to the server in the SilcIDListData
3054 structure. The status now includes the current status of
3055 the entry (like registered, resolved etc.). Affected file
3056 silcd/idlist.[ch]. Defined a bunch of different status types
3057 as well. This replaced the old boolean registered field as well.
3059 Added resolve_cmd_ident field to the SilcClientEntry structure
3060 too so that if the entry is for example being resolved so
3061 another command may attach to the same pending command reply
3062 without requiring to resolve the same entry again. This concept
3063 should optimize the WHOIS and the IDENTIFY resolving under
3064 heavy load by taking away unnecessary resolving for entries
3065 that are being resolved already.
3067 Added support for adding multiple pending commands for one
3068 command idenfier. Affected file silcd/command[_reply].[ch].
3070 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3071 before deleting the data. Otherwise the hash table will have
3072 freed data in comparison functions. Affected file is
3073 silcd/command_reply.c.
3075 * Fixed silc_idlist_replace_client_id to add the new entry to
3076 the cache with NULL nickname. Otherwise there will be invalid
3077 memory as the nickname after the nickname is freed. Affected
3078 file silcd/packet_receive.c.
3080 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3081 saved into wrong slots because the previous number of entries
3082 was not taken into account. Affected file silcd/idlist.c.
3083 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3085 * If we are router and we receive JOIN notify to a channel that
3086 does not have any users then notified client is marked as the
3087 channel founder, as it is it. The affected file is
3088 silcd/packet_receive.c
3090 * Added to the extended hash table API's table_del_*ext functions
3091 the destructor as argument too, so that the caller can decide
3092 which destructor to use or whether to use destructor at all.
3093 Affected file lib/silcutil/silchashtable.[ch].
3095 * Fixed ID Cache purging. It actually deleted the entries from
3096 the hash table after the data was freed. The hash table ended
3097 up comparing freed memory. The affected file is
3098 lib/silccore/silcidcache.c.
3100 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3102 * Fixed Irssi SILC client's KILL command's HELP syntax.
3104 * The USERS command now resolves the detailed user information
3105 if the userinfo field is missing. Affected file is
3106 lib/silcclient/command_reply.c.
3108 * Do not print error in silc_file_read if the read file does
3109 not exist. Just silently return NULL. Affected file is
3110 lib/silcutil/silcutil.c.
3112 * Fixed the silc_log_output to not wine about NULL filename
3113 and to not create some bogus " " filename. Affected file is
3114 lib/silcutil/silclog.c.
3116 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3118 * Fixed various printing bugs on the user interface in the
3119 Irssi SILC Client. Minor changes that were forgotten from
3122 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3124 * Fixed the configure.in.pre and the compilation and distribution
3125 environment to support the new autoconf 2.52. That version is
3126 now required to compile the CVS trunk.
3128 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3130 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3131 to generally parse user@fqdn format strings. Affected file
3132 lib/silcutil/silcutil.c.
3134 * Added nickname_format and nickname_force_format fields to the
3135 SilcClientParams structure. The first one defines the format
3136 for the nicknames that the library will enforce if the receives
3137 multiple same nicknames. The second one is boolean value and
3138 can be used to force the library to always enforce the format
3139 to the nicknames regardles whether there are multiple nicknames
3140 or not. This configurable formatting was employed to flexibly
3141 support accessing multiple nicknames from the user interface.
3142 The userinterface can now set the nicknames to what ever format
3143 they prefer. Affected file lib/silcclient/silcapi.h.
3145 Added function silc_client_nickname_format to the file
3146 lib/silcclient/idlist.c. It performs the nickname formatting.
3148 Added new field `hostname´ to the SilcClientEntry context.
3149 It holds the hostname of the client. Affected file is
3150 lib/silcclient/idlist.h.
3152 * Irssi SILC Client sets the nicknames in nick@hostn format.
3153 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3154 irssi/src/silc/core/silc-core.c.
3156 The WHOIS printing now also shows both the real nickname and
3157 the formatted nickname so that user knows how to access the
3158 user if there are multiple same nicknames cached. Affected
3159 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3160 printing formatting too to take the hostname now as a separate
3161 argument. The Affected file is
3162 irssi/src/fe-common/silc/modules-formats.[ch].
3164 * Changed the silc_client_get_clients_local to accept the formatted
3165 nickname as argument. It accepts the real nickname too but the
3166 formatted nickname can be used to find the true entry from
3167 multiple entries. Affected file lib/silcclient/silcapi.h and
3168 lib/silcclient/idlist.c.
3170 * Added nickname_format_parse field to the SilcClientParams.
3171 It is a callback function provided by the application to parse
3172 the nickname out of the formatted nickname string. The library
3173 calls it to get the nickname from the formatted string. Since
3174 the application generally knows better the format of the nickname
3175 string it parses it instead of the library, even though library
3176 encodes the formatted string. If the callback function is not
3177 provided then the library will use the string as is. The
3178 affected file is lib/silcclient/silcapi.h.
3180 * All the nickname strings passed to the client library in
3181 commands are now expected to be formatted nickname strings.
3182 If the command does not support the formatted nickname string
3183 it will assume that the sent string is the actual nickname.
3184 Affected file lib/silcclient/command.c.
3186 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3188 * Added public key authentication support to OPER and SILCOPER
3189 commands in the client library. Affected file is
3190 lib/silcclient/command.c.
3192 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Changed the get_auth_methdod client operation to be asynchronous.
3195 It can be async if the application resolves the authentication
3196 method from the server during the negotiation. Added new
3197 SilcGetAuthMeth completion callback that the application will
3198 call after resolving the authentication method.
3200 Added function silc_client_request_authentication_method that
3201 the application can use to resolve the authentication method
3202 from the server. Added also SilcConnectionAuthRequest callback
3203 that the library will call after the server has replied. The
3204 application can call this function if it does not know the
3205 current authentication method.
3207 Affected files are lib/silcclient/client.c and
3208 lib/silcclient/silcapi.h.
3210 * The Irssi SILC client now automatically resolves the authentication
3211 method incase any configuration information is not present (and
3212 currently there never is). The affected file is
3213 irssi/src/silc/core/client_ops.c.
3215 * Fixed public key authentication from the client library.
3216 Affected file lib/silcclient/protocol.c. Changed also the
3217 protocol specification about the public key authentication in
3218 the connection authentication protocol. The actual data to be
3219 signed is now computed with a hash function before signing.
3221 * Fixed the public key authentication from the server as well.
3222 Affected file silcd/protocol.c.
3224 * Removed the mlock()'s from the memory allocation routines.
3225 Affected file lib/silcutil/silcmemory.c. The ./configure does
3226 not check anymore for the mlock(). Affected file is
3229 * Fixed USERS command in server to allow the execution of the
3230 command for private and secret channels if the client sending
3231 the command is on the channel. Affected file silcd/command.c.
3233 * Fixed silc_client_get_clients_local to return the clients
3234 count correctly. It could return wrong value. Affected file
3235 lib/silcclient/idlist.c.
3237 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3239 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3240 types. The assembler optimizations seemed not to like 64-bit
3241 data types. The assmebler optimizations thus are now enabled
3242 also for BSD systems as opposed to only enable them for Linux.
3244 * Do not check for threads at all on BSD systems. Affected
3245 file configure.in.pre.
3247 * Removed -n and -h options from the Irssi SILC Client since
3248 they are not used in silc.
3250 * Fixed the prime generation to assure that the first digit
3251 of the generated random number is not zero since our conversion
3252 routines does not like number strings that starts with zero
3253 digit. If zero digit is seen the random number is regenerated.
3254 This caused some corrupted RSA keys when the zero first digit
3255 was met. Affected file lib/silcmath/silcprimegen.c.
3257 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3259 * Fixed WIN32 configuration in the ./configure script.
3260 Fixed to include xti.h on environments that has it.
3261 Patches by Carsten Ilchmann and andrew.
3263 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3265 * Changed the silc_id_create_client_id to be collision
3266 resistant. It is now assured that there cannot be created
3267 two same client ID's. I suspect that some weird bugs in
3268 the server were actually caused by duplicate Client IDs.
3269 Affected file silcd/serverid.[ch]. A router receiving
3270 new ID now also assures and informs the sending server
3271 if the ID caused collision.
3273 * Changed the silc_id_create_channel_id to also assure that
3274 there are no collisions.
3276 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3278 * Statement about ignoring the Mutual Authentication flag when
3279 performing rekey with PFS was a bit misleading. It is ignored
3280 if it was set in the initial negotiation, it cannot be even
3281 set in the rekey. Fixed in the ke-auth draft. Started the
3282 new versions of the protocol drafts in the doc/.
3284 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3286 * Fixed a bug in silc_client_command_identify_save when saving
3287 new channel information. The channel name was no duplicated
3288 and caused crash on exit. Affected file is
3289 lib/silcclient/command_reply.c.
3291 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Fixed the getkey command handling in the server. Send just
3294 empty OK reply to the sender if the key could not be fetched
3295 (but everything else was ok, like the key just was not available).
3296 Changed the public key parameter to optional in the protocol
3297 specs so that empty OK reply can be sent. Affected file
3300 Added a message to Irssi SILC client to tell to user if the
3301 server did not return a public key.
3303 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * Fixed a channel key regeneration bug. It registered new
3306 timeout tasks exponentially until all system resources were
3307 used. Affected file silcd/server.c.
3309 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3311 * Added the SILC Document generator to the scripts/silcdoc.
3312 It can be used to generate the Toolkit Reference Manual out
3313 of the source tree. Internally it will also use the RoboDoc
3314 generator now imported in util/robodoc.
3316 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * Added couple of return's in rekey protocol if error orccurred
3319 during the protocol. The execution must be terminated.
3320 Affected file silcd/protocol.c. Also, terminate the protocol
3321 always with timeout.
3323 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * The client's Client ID was created initally from the wrong
3326 nickname (it could have been in format nick@host) in the
3327 silc_server_new_client. Affected file silcd/packet_receive.c
3329 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3331 * Added some SILC_LOG_ERROR's to various error conditions
3332 if client could not be added to ID cache. Affected files
3333 silcd/packet_receive.c and silcd/server.c.
3335 * When client's sock->user_data is freed, NULL also the
3336 client->router and client->connection pointers. Added check
3337 for these pointers being NULL to various places around the
3338 code. Affected file silcd/server.c.
3340 * Added client->data.registered == TRUE checks to various
3341 places around the code to assure that unregistered client's
3342 are not handled when it is not allowed. Affected file
3345 * Added `bool registered' fields to all
3346 silc_idlist_[server|client]_get_* routines to indicate whether
3347 the fetched client needs to be registered or not. Affected
3348 file silcd/idlist.[ch].
3350 * Add your own entry as registered to the ID cache in the
3351 server. Affected file server.c.
3353 * Fixed a bug in silc_server_new_server. The SilcServer was
3354 set as the new server's context instead of SilcServerEntry.
3355 This naturally caused some weird bugs.
3357 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3359 * Do not delete the channel rekey task when adding it
3360 for in silc_server_create_channel_key.
3362 * Changed the silc_server_create_channel_key to return
3363 TRUE or FALSE to indicate the success of the channel key
3366 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3368 * Fixed MSVC++ project files and added missing files to
3369 Makefiles under win32/.
3371 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3373 * Do not add TCP_NODELAY flag if the operating system
3374 does not have it defined. Affected files are
3375 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3377 * Fixed buffer overflow from Irssi SILC Client. Affected
3378 file irssi/src/fe-common/core/themes.c.
3380 * Fixed double free in client library in the file
3381 lib/silcclient/client.c when disconnecting from server.
3383 * Applied double free patch from cras to Irssi SILC client.
3384 Affected files irssi/src/core/[modules/expandos].c
3386 * Fixed the disconnection handling to Irssi SILC Client.
3387 The application must call silc_client_close_connection
3388 in ops->connect client operation in case of failure of
3389 the connection. Affected file is
3390 irssi/src/silc/core/client_ops.c.
3392 * Do not set sock->protocol to NULL in the function
3393 silc_client_close_connection after executing the protocol's
3394 final callback since the sock might not be valid anymore.
3395 Affected file lib/silcclient/client.c.
3397 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3399 * Do not enable SILC_THREADS if the linking with libpthread
3400 did not happen. Affected file configure.in.pre.
3402 * Added notion to protocol specification that server must
3403 verify the sent authentication payload with CMODE when
3404 setting the channel founder key. Implemented it to the
3405 server. Affected file silcd/command.c.
3407 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3409 * Added _EXTRA_DIST SILC distribution variable to the
3410 distributions file. It is used to conditionally add extra
3411 files or directories to the specific distribution. Affected
3412 files ./prepare, Makefile.am.pre and distributions.
3414 Removed the `_' from the start of the distribution names.
3417 * Added README.WIN32 for instructions to compile the Toolkit
3420 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3422 * Fixed a double free in disconnection in the server. Affected
3423 file is silcd/server.c.
3425 * Fixed the lib/silcske/groups.c to work now also with GMP
3426 MP library. The string conversion did not work when using
3427 specific base and the base is indicated in the string as well.
3429 * Created win32/ directory which now includes MSVC++ specific
3430 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3431 It will appear only in the toolkit distribution
3433 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3435 * Changed the key material distribution function in case when
3436 the hash output is too short. The data is now concatenated
3437 a bit differently than it used to. Made the change to the
3438 SKE protocol specification.
3440 * Added better GMP detection to configure.in.pre. A patch
3443 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3445 * Fixed a minor bug in SKE that might cause some problem on
3446 some platforms. Affected file lib/silcske/silcske.c.
3448 * Added the cookie checking for initiator in the SKE. It checks
3449 that the responder returns the sent cookie unmodified. The
3450 affected file is lib/silcske/silcske.c. Added new SKE
3451 error type INVALID_COOKIE that can be sent during the
3452 negotiation. Fixed some memory leaks as well.
3454 * Added the "invalid cookie" error message to Irssi SILC client's
3457 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * Added `task_max' field to the SilcClientParams to indicate
3460 the maximum tasks the scheduler can handle. If set to zero,
3461 default values are used. Affected file lib/silcclient/silcapi.h.
3463 * Fixed memory leaks in silc_client_close_connection. Affected
3464 file lib/silcclient/client.c.
3466 * Added silc_client_del_client_entry to client library to free
3467 all memory of given client entry. Affected file is
3468 lib/silcclient/idlist.[ch].
3470 * Added new functions silc_client_del_channel and
3471 silc_client_del_server to delete channel and server entries.
3472 Affected file lib/silcclient/[silcapi.h/idlist.c].
3474 * Removed silc_client_del_client_by_id from silcapi.h.
3476 * Fixed the INFO command to return the server's own info
3477 correctly when querying by Server ID. Affected file is
3480 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3482 * Removed the non-blocking settings in WIN32 code in the
3483 silc_sock_[read/write] and added SleepEx instead. Affected
3484 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3485 of input data is now checked with FIONREAD and ioctlsocket.
3487 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3489 * Call silc_schedule_task_del_by_context in the
3490 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3491 Affected file lib/silccore/silcprotocol.c.
3493 * Call silc_protocol_cancel for active protocols in the
3494 silc_server_close_connection if the funtion
3495 silc_server_free_sock_user_data has not been called.
3496 Affected file silcd/server.c.
3498 * Generic tasks cannot be deleted using the del_by_fd
3499 task deleting function since generic tasks does not match
3500 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3502 * Added a notion to SILCOPER help file that the SILCOPER works
3503 only on router server, not on normal server.
3505 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3507 * Added for WIN32 support for the new scheduler as well.
3508 Affected file lib/silcutil/win32/silcwin32schedule.c.
3510 * Fixed the SHA1 implementation to work on various platforms.
3512 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3514 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3515 API. It is part of the scheduler now. Everything else is
3516 as previously but some functions has changed their names.
3517 Checkout the lib/silcutil/silcschedule.h for the interface.
3518 Updated all applications to use the new interface. Affected
3519 files are lib/silcutil/silcschedule.[ch].
3521 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3523 * Found a bug in the SKE implementation. The HASH value,
3524 specified by the protocol, was not computed correctly. The
3525 public key of the responder was not added to the computation
3526 even though it is mandatory. Affected file lib/silcske/silcske.c.
3527 This unfortunately causes incompatibilities with older
3528 clients and servers.
3530 * Added WIN32 specific network init and uninit functions:
3531 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3532 the Winsock2. Affected file lib/silcutil/silcnet.h and
3533 lib/silcutil/win32/silcwin32net.c.
3535 * Set the socket always to nonblocking mode on WIN32 after
3536 reading data or writing data. Affected file is
3537 lib/silcutil/win32/silcwin32sockconn.c.
3539 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3541 * Fixed various compilation problems under WIN32. Affected
3542 files lib/silcutil/win32/silcwin32thread.c and
3543 lib/silcutil/win32/silcwin32schedule.c.
3545 * Removed all _internal.h #includes from public header
3546 files. Internal headers must never be included from
3549 Removed also the lib/silcske/payload_internal.h file.
3551 * All include files that may be needed (public and some others
3552 included by the public headers) by application developers are
3553 now copied to the ./includes directory. It does not copy any
3554 internal headers. Affected file Makefile.defines.pre and all
3555 Makefile.am's under lib/ and subdirs.
3557 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3559 * Do not change the ~/.silc directory's permissions automatically.
3560 Affected file irssi/src/silc/core/clientutil.c.
3562 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * Do not cancel the protocol in silc_server_close_connection
3565 it might cause recursion. Now cancelled in the function
3566 silc_server_free_sock_user_data. Affected file silcd/server.c.
3568 * Fixed the silc_server_remove_clients_by_server to regenerate
3569 the channel keys correctly finally. Added also new function
3570 silc_server_remove_clients_channels to actually do it.
3571 Affected file silcd/server.c.
3573 * Fixed the silc_server_new_channel to not crash by giving
3574 wrong router to the new channel. Affected file is
3575 silcd/packet_receive.c.
3577 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3579 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3580 which is given as argument to the silc_client_alloc now.
3581 It can be used to configure the client and set various parameters
3582 that affect the function of the client.
3584 * The USERS command in server did not check whether the channel
3585 is private or secret. Affected file silcd/command.c.
3587 * Added new argument to the USERS command in protocol specification.
3588 The USERS command now can take the channel name as argument
3589 as well. Added support for this in client and server and
3590 updated the protocol specs.
3592 * Completed the GETKEY command in client. It can be now used
3593 to fetch also servers public key not only some clients.
3594 Affected files lib/silcclient/command[_reply].c.
3596 * Added silc_client_get_server to return server entry by the
3597 server name. Affected files lib/silcclient/silcapi.h and
3600 * Redefined the IDENTIFY command in protocol specification to be
3601 more generic. It now can be used to query information about
3602 any entity in the SILC Network, including clients, servers and
3603 channels. The query may be based either the entity's name
3604 or the ID. Added support for this in both client and server.
3606 Affected files silcd/command.c and lib/silcclient/command.c
3607 and command_reply.c.
3609 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3610 the _from_client and _from_server functions. Affected file
3613 * Added silc_client_get_channel_by_id_resolve to the file
3614 lib/silcclient/silcapi.h to resolve channel information by
3615 its ID. Added also silc_client_get_channel_by_id that
3616 does not resolve it from the server.
3618 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3620 * Added SilcServerEntry context into the client library
3621 to represent one server. The INFO command now allocates
3622 these to save the resolved server info. For now on the
3623 client library will also keep information about servers,
3624 connected and resolved with INFO.
3626 The INFO command now allocates the SilcServerEntry context
3627 and saves the server info there. The COMMAND_REPLY in
3628 the INFO now returns the parameters to application in
3629 same order as defined in the protocol specification.
3631 The entries are cached in the client->server_cache.
3633 * The INFO command is now issued after received the Client ID
3634 from the server. Affected file lib/silcclient/client.c.
3636 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3637 to the application as the mode changer might be server.
3638 It is guaranteed that NULL is not returned anymore to the
3639 application. Affected file lib/silcclient/client_notify.c.
3641 The ID Type is now also passed to the application so that
3642 it can check whether the returned entry is SilcClientEntry
3645 Added new function silc_client_get_server_by_id to return
3646 the server entry by ID. Affected files are the
3647 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3649 * Do not create the channel in the Irssi SILC Client when issuing
3650 the JOIN command but when received the sucessful JOIN command
3651 reply. Otherwise the channel might get created even though we
3652 could not join it. The Affected file is
3653 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3655 * Fixed a channel joining bug in router. The router must also
3656 check the channel modes, invite and ban lists etc. when serving
3657 the JOIN command sent by normal server. Affected file is
3658 silcd/command.c. The router now resolves the client's
3659 information from the server who sent the JOIN command if it
3660 does not know it, and processes the JOIN command only after
3663 * Changed the SilcCommandCb to take new argument; void *context2.
3664 Affected file lib/silccore/silccommand.h
3666 The second argument in the command callbacks in the server now
3667 includes the SilcServerCommandReplyContext if the command was
3668 called as pending command callback from the command reply.
3669 Otherwise it is NULL. When called as pending the status of the
3670 command reply will be checked and if it was erronous the
3671 error will be sent to the original sender of the command.
3672 This way the client always receives the error messages even
3673 though the server was actually the one who received the error
3674 when it resent the command to router, for example. Affected
3675 files silcd/command[_reply].[ch].
3677 * Fixed sending WHOWAS command's error message to client if
3678 the requested client could not be found. It was missing.
3681 * Changed the CMODE and CUMODE commands reply arguments in the
3682 protocol specification. The Channel ID is now sent in both
3683 of the commands to identify the channel. Implemented this
3684 new feature to the client and server. Affected files
3685 lib/silcclient/command_reply.c and silcd/command.c.
3687 * Made better checks for invite and ban lists in the JOIN
3688 command in server. Affected file silcd/command.c.
3690 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3692 * The server now performs the incoming host IP/DNS lookup
3693 using the silc_socket_host_lookup and thus does not block
3694 the server anymore. Affected file silcd/server.c.
3696 * Completed the multi-thread support for SILC Scheduler in
3697 the lib/silcutil/silcschedule.c.
3699 * Fixed the configure.in.pre to detect the pthread correctly
3702 * Fixed a deadlock in silc_task_queue_wakeup in the file
3703 lib/silcutil/silctask.c.
3705 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3707 * Added new function silc_schedule_wakeup that is used in
3708 multi-threaded environment to wakeup the main thread's
3709 schduler. It needs to be used when a thread adds a new task
3710 or removes a task from task queues. After waking up, the
3711 scheduler will detect the task queue changes. If threads
3712 support is not compiled in this function has no effect.
3713 Implemented the wakeup mechanism to both Unix and WIN32
3714 systems. Affected files are lib/silcutil/silcschedule.[ch],
3715 lib/silcutil/unix/silcunixschedule.c and the
3716 lib/silcutil/win32/silcwin32schedule.c.
3718 * Added new function silc_task_queue_wakeup to wakeup the
3719 scheduler by the specified task queue. Affected file
3720 lib/silcutil/silctask.[ch].
3722 * The silc_socket_host_lookup_start now wakes up the scheduler
3723 after adding the timeout task. Affected file is
3724 lib/silcutil/silcsockconn.c.
3726 * The silc_socket_host_lookup is synchronous now if the threads
3727 support is not compiled in. However, the callback is still
3728 called asyncronously through the scheduler, anyway. Affected
3729 file lib/silcutil/silcsockconn.c.
3731 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Added new function silc_socket_host_lookup to perform
3734 asynchronous IP and FQDN lookups for the socket connection.
3735 Affected files lib/silcutil/silcsockconn.[ch].
3737 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3739 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3740 that may or may not compile the mutex support in.
3742 Changed the silc_mutex_alloc interface. It allocates the
3743 mutex now to the sent pointer and returns TRUE or FALSE.
3745 Affected file lib/silcutil/silcmutex.h.
3747 * Wrote the SILC Task Queue interface to support multi-threads.
3748 Affected file lib/silcutil/silctask.[ch].
3750 * Wrote the SILC Scheduler to support multi-threads. Affected
3751 file lib/silcutil/silcschedule.c.
3753 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3755 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3756 in lib/silcutil/win32/.
3758 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3760 * Defined SILC Mutex API and SILC Thread API and implemented
3761 them for Unix. Affected files are
3762 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3763 lib/silcutil/unix/silcunixmutex.c and
3764 lib/silcutil/unix/silcunixthread.c.
3766 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3768 * Fixed the silc_server_remove_clients_by_server's channel
3769 key re-generation. The hash table handling was incorrect
3770 and would not work with many channels. Affected file is
3773 * Fixed some memory leaks around the server code.
3775 * Rewrote the silc_server_get_users_on_channel to support IPv6
3776 based Client ID's. Affected file silcd/server.c.
3778 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3779 specification. However, a separate document must be written
3780 to define the detailed signing procedure and the payload
3781 associated with the flag. Defined the flag to the
3782 lib/silccore/silcchannel.h as well.
3784 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3786 * Changed the dynamic tables to static size tables in the
3787 lib/silccrypt/silchmac.c.
3789 * Removed GCC dependencies from the code. A patch by cras.
3791 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3793 * Do not show the error "Error receiving packet bla bla"
3794 in server if it really was not an error (-2 means that reading
3795 is pending). Affected file silcd/server.c.
3797 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3799 * Fixed a possible crash in silc_server_remove_clients_by_server
3800 in silcd/server.c. Fixed there also some memory leaks.
3802 * Fixed the silc_idlist_replace_client_id. It could replace
3803 wrong key in the hash table. Affected file silcd/idlist.c.
3805 * Do not check whether there are global users on the channel
3806 if the channel->global_users is FALSE. Affected functions
3807 silc_server_remove_from_one_channel and
3808 silc_server_remove_from_channels in silcd/server.c. Also,
3809 do not check if the removed client is local as we can be
3810 sure that global client was not removed from the channel
3811 and checking for global users is not needed.
3813 * The silc_server_remove_clients_by_server now re-generates
3814 the channel keys correctly for those channels that had
3815 clients removed from them. Affected file silcd/server.c.
3817 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3819 * Found the reason of random crashes in the server. We weren't
3820 ignoring the SIGPIPE signal (which can be sent in write())
3821 and it crashed the server. Affected file silcd/silcd.c.
3823 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3825 * Assure that sock->user_data is not NULL in the function
3826 silc_server_packet_send in silcd/packet_send.c.
3828 * Disconnect the remote connection if it could not be added
3829 to any ID lists in the server. The affected file is
3832 * Check in silc_server_packet_send[_real/dest] that the
3833 socket is not disconnecting and ignore the data if it is.
3834 Affected file silcd/packet_send.c.
3836 * Define inline to __inline on native WIN32 compilation.
3837 Affected file includes/silcwin32.h.
3839 * Added some explicit type casts for inline code since MSVC
3840 require them. Affected files lib/silcutil/silcbuffer.h,
3841 lib/trq/silcdlist.h and lib/trq/silclist.h.
3843 * Print warning in log files from now on if the packet
3844 decryption fails. Affected file silcd/server.c.
3846 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3848 * Changed the `say' client operation's interface to accept
3849 new `type' argument to indicate the type of the message sent
3850 by the library. The application may filter the library's
3851 messages according the type. The affected file is the
3852 lib/silcclient/silcapi.h.
3854 * Added two new functions to lib/silcclient/silcapi.h:
3855 silc_client_del_client and silc_client_del_client_by_id.
3856 Affected file lib/silcclient/idlist.c.
3858 * Moved the clientincludes.h from includes/ to silc/ and
3859 serverincludes.h from includes/ to silcd/.
3861 * The modes for the CMODE and CUMODE are now passed as
3862 uint32 for application with COMMAND_REPLY. The affected
3863 file is lib/silcclient/command_reply.c.
3865 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3867 * /WHOIS without arguments shows client's own information.
3868 Affected file lib/silcclient/command.c.
3870 * Changed PING to not accept any arguments. The specs
3871 says that client can ping only the connected server so
3872 requiring an argument is not needed. Affected file is
3873 lib/silcclient/command.c.
3875 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3877 * Fixed a fatal bug in private message sending and reception
3878 encryption and decryption when using private message keys.
3879 The implementation was incorrect and did not follow the
3880 specification. It causd that some of the message were
3881 lost since it did not use the sending and receiving keys
3882 as the protocol suggests. This has been fixed and will cause
3883 incompatibilities with older clients when sending private
3884 message encrypted with private message keys. Affected files
3885 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3886 and various other in Irssi SILC Client.
3888 Added `responder' boolean argument to the functions
3889 silc_client_add_private_message_key[_ske] to indicate when
3890 the key is added as responder or initiator of the key
3893 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3895 * Removed the silc_ske_check_version function and created
3896 a SilcSKECheckVersion callback. Added also a function
3897 silc_ske_set_callbacks that is now used to set all SKE
3898 callbacks. The callback functions are not given to
3899 the SKE functions anymore, but this function is used to
3902 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3904 * Added `silc_version' argument to the silc_client_alloc
3905 to define the version of the application for the library.
3906 The library will use the version string to compare it
3907 against the remote host's (usually a server) version
3908 string. Affected file lib/silcclient/silcapi.h
3910 * Added the KE protocol context to Key Agreement context
3911 in client library so that we can abort the SKE if it
3912 is in process when we get timeout. Affected file is
3913 lib/silcclient/client_keyagr.c.
3915 * Do not resolve the client ID forever if it returns in the
3916 first time that such client does not exist. This was done
3917 for example with private message. Affected file is
3918 lib/silcclient/client_prvmsg.c.
3920 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3922 * Do not add regex.h for WIN32. The affected file
3923 includes/silcincludes.h.
3925 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3926 not work yet 100%. It generates the DLL's automatically
3927 when compiling with --with-win32 under cygwin.
3929 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3931 * lib/contrib/regex.c is not compiled on WIN32.
3933 * Added silc_net_get_socket_opt function to the
3934 lib/silcutil/silcnet.h.
3936 * Added includes/silcwin32.h for WIN32 specific includes
3939 * Do not use ptime structure or any of the posix process
3940 functions on WIN32 in lib/silccrypt/silrng.c.
3942 * Added silc_gettimeofday to provide generic function
3943 for struct timeval on all platforms. Added the function
3944 to lib/silcutil/silcutil.h.
3946 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3948 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3949 library as they clearly belong there. As a plus side we
3950 can make the actual socket connection routines platform
3953 Added also new generic function silc_socket_read and
3954 silc_socket_write (that used to be silc_packet_[read/write].
3955 The implementation of these are platform specific.
3957 * Added WIN32 specific routines of silc_socket_[read/write]
3958 to lib/silcutil/win32/silcwin32sockconn.c.
3960 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3962 * Added preliminary support for native WIN32 compilation under
3963 cygwin (using the -mno-cygwin option for GCC) to the
3964 ./configure.in.pre. The --with-win32 now prepares the
3965 compilation for native WIN32.
3967 * Rewrote the SILC Scheduler interface in the file
3968 lib/silcutil/silcschedule.h. The scheduler is now context
3969 based and does not have anymore any global static scheduler.
3970 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3971 and created lib/silcutil/win32 directory for WIN32 based
3974 * Added Unix specific network routines to the
3975 lib/silcutil/unix/silcunixnet.c and the old
3976 lib/silcutil/silcnet.c includes now only generic routines.
3978 Added WIN32 specific network routines to the
3979 lib/silcutil/win32/silcwin32net.c.
3981 * Added Unix specific utility functions from the
3982 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3984 * Added WIN32 SILC Scheduler to the file
3985 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3988 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3990 * Do not handle JOIN notify in the server if the target client
3991 is not registered (idata->registered == FALSE). The affected
3992 file is silcd/packet_receive.c.
3994 * Update the nickrec->founder in event_cumode in the Irssi SILC
3995 client. Affected file irssi/src/silc/core/silc-channels.c.
3997 * Fixed the CUMODE_CHANGE notify handling in the server when
3998 server and router are announcing their clients on channels.
3999 Now the mode changes are saved and notified correctly. The
4000 affected file is /silcd/packet_receive.c.
4002 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4003 They really did not replace the cache entry in the ID Cache.
4004 Now they do that. Affected file silcd/idlist.c.
4006 * Fixed the KICK notify handling in the Irssi SILC client to
4007 update the channel records so that the kicked client does not
4008 appear to be on the channel. The affected file is
4009 irssi/src/silc/core/silc-channels.c.
4011 * Always update the conn->current_channel when executing command
4012 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4014 * Fixed the KILL notify handling in Irssi SILC client to remove
4015 the killed client on all channels.
4017 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4019 * Fixed the silc_parse_command_line to remove extra spaces
4020 from the start and end of the arguments. Affected file is
4021 lib/silcutil/silcutil.c.
4023 * Cancel and free any active protocol in the function
4024 silc_server_close_connection. Affected file silcd/server.c.
4026 * Cancel and free any active protocol in the function
4027 silc_client_close_connction. Affected file is
4028 lib/silcclient/client.c.
4030 * Do not execute the KILL command for clients that are in
4031 history (ie. they are not in the network). Affected file is
4034 * Fixed KILL notify handling, client does not crash anymore.
4035 Affected file irssi/src/silc/core/silc-channels.c.
4037 * Reduced the default packet buffer size from 2048 to 1024 in
4038 lib/silccore/silcpacket.c.
4040 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4041 counter to the SKE context that is incresed when the SKE library
4042 performs async operation outside the library. If the outside
4043 process frees the SKE context and FREED status will be set
4044 and the library will detect after the sync operation that the
4045 libary is freed. The affected files are
4046 lib/silcske/silcske[_status].[ch].
4048 * Resolve the client entry information in the function
4049 silc_client_channel_message to assure that NULL pointer is not
4050 passed as client entry to the application. */
4052 * Fixed the task timeout calculation to assure that there is
4053 never negative timeouts. The affected file is
4054 lib/silcutil/silcschedule.c.
4056 * Fixed the channel user mode notification sending in server.
4057 It was sent point-to-point to the router (or to server by router)
4058 but it needs to be destined to a channel. The routines now
4059 supports sending the channel user mode notifys to the channels
4060 when announcing clients and channels. Affected files are
4061 silcd/server.c and silcd/packet_receive.c.
4063 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4064 It did not actually replace the old channel entry in the cache.
4065 Affected file lib/silcclient/client_notify.c.
4067 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Fixed a possible crash in silc_packet_send_prepare. It now
4070 assures always that there is enough space in the buffer and
4071 at the tail area of the buffer (for MAC).
4073 Fixed the inbound buffer reallocation in silc_packet_read.
4074 It was old code and did not handle the reallocation correctly.
4077 The affected file is lib/silccore/silcpacket.c.
4079 * Fixed buffer overflow in silc_parse_nickname in the file
4080 lib/silcutil/silcutil.c.
4082 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * make install generates new server keys only if there is not
4087 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4090 Added check that if the NOREPLY is set then we will not send
4091 the away message. This avoids infinite loop of away messages
4092 if both clients are away. The affected file is
4093 lib/silcclient/client_prvmsg.c.
4095 * Fixed client crash if /NICK was given without arguments.
4096 Affected file lib/silcclient/command.c.
4098 * Server does not send the invite list in INVITE command back
4099 to the client if the list was not altered. Added this notion
4100 to the protocol spec as well. Affected file silcd/command.c.
4102 Fixed possible crash in INVITE command by checking the
4103 value of silc_server_get_client_route command.
4105 * Fixed the INVITE notify type handling. The arguments are now
4106 taken in correct order and client does not crash. The affected
4107 file is irssi/src/silc/core/silc-channels.c.
4109 Removed the "Inviting xxx to channel" message from the
4110 client library away and let the application handle it.
4111 Affected file lib/silcclient/command.c. Added that message
4112 to Irssi SILC client's message formats.
4114 * Fixed CMODE command crash in client. It now checks the
4115 amount of arguments correctly and does not crash. The affected
4116 file is lib/silcclient/command.c.
4118 * Do not create new channel automatically in silc_channels_join
4119 but check whether the channel by that name already exists.
4120 Affected file irssi/silc/core/silc-channels.c.
4122 * Do not send the SERVER_SIGNOFF to router if the disconnected
4123 entity was the router. Affected file silcd/server.c.
4125 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4126 SILC client as it was missing from there.
4128 Added the handling of the KICK notify to the Irssi SILC client
4129 as it was missing. Added "you have been kicked" message to
4130 Irssi SILC client's message modules formats.
4132 Added the handing of the KILL notify to the Irssi SILC client
4133 as it was missing. Added the kill message module formats
4136 The affected file is irssi/src/silc/core/silc-channels.c.
4138 * The router did not save the channel mode the server announced.
4139 Affected file silcd/packet_receive.c.
4141 * Fixed a possible crash in INFO command in server. If the
4142 server did not provide the server info it crashed. Affected
4143 file silcd/command.c.
4145 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Fixed the GETKEY command in the server to check also the
4148 global list. Otherwise the GETKEY would not work correctly
4149 in normal SILC server. Affected file silcd/command.c.
4151 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Fixed GETKEY crash, it crashed if the command did not succseed.
4155 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4158 is now real and not just an macro interface to GMP.
4160 Removed the entire GMP from the source tree and imported new
4161 NSS MPI library instead. Reason for removing GMP is that it is
4162 extremely large and compiles extremely slow. The NSS MPI
4163 is only a few files and compiles in less than 10 seconds.
4164 The speed is also about the same as GMP. The MPI is imported
4165 to lib/silcmath/mpi.
4167 If the system has GMP installed we will still use the GMP.
4168 If it is not then the NSS MPI will be compiled.
4170 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Merged a long nickname (127 characters long) crash bugfix from
4173 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4175 * Merged a freed memory reference bugfix from Irssi CVS tree.
4176 Affected file irssi/src/core/commands.c.
4178 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Added the server's public key sving and verification to the
4181 server when performing the SKE. This was missing and the
4182 remote server's (or router's) public key was accepted without
4183 checking whether we have it previously or trust it at all.
4184 Affected file silcd/protocol.c.
4186 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Check in the silc_server_timeout_remote if protocol is active
4189 and make sure that the protocol's final callback is called so
4190 that all memory if freed. Affected file silcd/server.c.
4192 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * silc_server_whois_send_reply crashed the server if the nickname
4195 was 127 characters long. Affected file silcd/command.c.
4197 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Added sanity check to the silc_server_new_client. If the hostname
4200 is provided inside username then check that the provided hostname
4201 really is the same as the resolved one. If the hostname was not
4202 resolved then check it from the public key. Affected file is
4203 silcd/packet_receive.c.
4205 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4206 if the server disconnected us and the connection is not valid
4207 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4209 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4210 the library to the lib/silcutil/silcutil.[ch].
4212 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Close log file after open. Affected file
4215 lib/silcutil/silclog.c.
4217 * Check whether sock == NULL in silc_client_send_packet and return
4218 if it is. Affected file lib/silcclient/silcclient.c.
4220 * Check rec->entry == NULL in the Irssi SILC Client before
4221 sending the channel message. Affecte file is
4222 irssi/src/silc/core/silc-servers.c.
4224 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Merged a splitted window bugfix from Irssi CVS tree. The
4227 affected file is irssi/src/fe-text/textbuffer-view.c.
4229 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4230 It did not print nickname.
4232 * Improved the distributions system a bit.
4234 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4237 irssi/src/fe-text/gui-window.c.
4239 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4240 to in-active server. The affected file is
4241 irssi/src/silc/core/client_ops.c.
4243 * Resolve the client in USERS command reply if the entry does
4244 not have username resolved. The affected file is
4245 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4246 command to WHOIS command to really resolve stuff. The USERS
4247 is not used any more in any critical section so WHOIS can
4248 be used even though it might be slower than IDENTIFY.
4250 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4253 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Changed the protocol API a bit more consistent in the
4256 lib/silccore/silcprotocol.[ch].
4258 * Changed the following headers to ROBODoc format:
4260 lib/silccore/silcpayload.h
4261 lib/silccore/silcprotocol.h
4262 lib/silccore/silcsockconn.h
4264 All core library headers are now formatted.
4266 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Fixed a bug in Irssi SILC client; do not show that you are
4269 server/router operator if you really are not. Affected file is
4270 irssi/src/silc/core/client_ops.c.
4272 * Renamed silc_command_free_payload to silc_command_payload_free.
4273 Affected file lib/silccore/silccommand.h
4275 * Added silcmath.h to include the prototoypes of various routines
4276 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4279 * Changed the following headers to ROBODoc format:
4281 lib/silccore/silcchannel.h
4282 lib/silccore/silccommand.h
4283 lib/silccore/silcid.h
4284 lib/silccore/silcidcache.h
4285 lib/silccore/silcmode.h
4286 lib/silccore/silcnotify.h
4287 lib/silccore/silcpacket.h
4288 lib/silcmath/silcmath.h
4290 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Added checking to the server code not to start the server if
4293 ciphers and stuff are not configured properly. Affected files
4294 silcd/serverconfig.[h] and silcd/server.c.
4296 * Changed the layout of the header files of the public interfaces
4297 in the SILC libraries. The new layout supports ROBODoc
4298 documentation tool (and some others) so that it is easy to create
4299 a library reference manual. All the other headers and source
4300 code must still follow the CodingStyle document. Also source
4301 code must not include these ROBODoc stuffs, only the headers.
4302 Furthermore, all public interface headers must now be named
4303 by using `silc' prefix, example: silcapi.h, silccipher.h.
4304 Some files were renamed due to this. All the other headers
4305 must not be used as public interfaces. I will update the
4306 CodingStyle document later. Changed following headers, so far:
4308 lib/silcclient/silcapi.h
4309 lib/silccore/silcauth.h
4310 lib/silccore/silcprivate.h
4311 lib/silccrypt/silcdh.h
4313 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Removed silc_client_packet_send_flush from the client library
4318 as it is not needed. Affected file lib/silcclient/client.[ch].
4320 * Added printing of message of unresolved authentication method
4321 to the Irssi SILC client. Added it to the module formats.
4322 Removed the same message from the client library.
4324 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Added new distribution feature, DISTLABEL. Every distribution
4327 can define own preprocessor label that can be used in the
4328 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4329 file distributions, acconfig.h.pre and prepare.
4331 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Added Makefile.defines_int to include the actual definitions
4334 for Makefile.defines.in. Tested the new distribution system,
4335 created distributions and tested installation.
4337 * Added AWAY message printing to the Irssi SILC client. Added
4338 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4340 * Added SCONNECT command to call the SILC's CONNECT command.
4341 Cannot use CONNECT directly since Irssi uses that internally.
4342 Affected file irssi/src/silc/core/silc-servers.c.
4344 Added ACTION local command. It is same as ME command but takes
4345 the channel as mandatory argument.
4347 Rewrote some of the Irssi's help files to suite for SILC
4350 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4352 * Added Makefile.defines[.in] that should for now on be included
4353 in all Makefile.am file in the source tree. That file includes
4354 all common compilation definitions for SILC source tree.
4356 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Minor changes to the ./prepare script to change the package
4359 name according the distribution name to the configure.in.
4361 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4363 * Created new distribution system. Added file `distributions'
4364 that defines all the distributions that can be created out of
4365 the SILC source tree. The ./prepare script now reads that
4366 file to determine how to prepare the distributions. The
4367 first argument to the ./prepare is the name of the distribution
4368 and second is the version of the distribution. If given
4369 without arguments it creates the default (toolkit) distribution
4370 with the default version (defined in ./prepare).
4372 All Makefile.am files that are subject to the distributions
4373 are now named as Makefile.am.pre. These are ./Makefile.am
4374 and lib/Makefile.am. Others may be changed later.
4376 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Added invite list, ban list, some key management and connection
4379 error message printing to module formats in the Irssi SILC client.
4381 * Added new silc_client_set_away_message to set the away message
4382 that is back to the person who sent private message. The
4383 affected file lib/silcclient/silcapi.h and the
4384 lib/silcclient/client_prvmsg.c.
4386 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Fixed the private message sending in the Irssi SILC client,
4389 added local command KEY to the Irssi SILC client.
4391 Added key management and key agreement message formats to the
4392 irssi/src/fe-common/silc/module-formats.[ch].
4394 Added USERS (alias WHO) printing, server/router operator
4395 indication and LIST command printing to the module formats.
4397 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Fixed channel joining notify handling, cumode notify handling
4400 from Irssi SILC client.
4402 * Added SILC specific module-formats to the Irssi SILC client so
4403 that SILC specific message hilighting, colors etc is possible.
4404 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4406 Added channel mode, channel user mode, actions, notices,
4407 whois and whowas printing to the the module-formats.c.
4409 * Fixed a bug in channel deletion in the server. The channel
4410 is not left to the cache even if the channel founder auth mode
4411 is set when there are no users anymore on the channel. Affected
4412 file silcd/server.c.
4414 * The silc_net_localhost now resolves the entire hostname including
4415 the domain name. Affected file lib/silcutil/silcnet.c.
4417 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Changed the ask_passphrase client operation to be ascynchronous.
4420 It has now a completion callback and a context that the
4421 application must call after it has got the passphrase from
4422 the user. Affected files lib/silcclient/silcapi.h,
4423 lib/silcclient/protocol.c, lib/silcclient/command.c and
4426 Added SilcAskPassphrase callback that the application calls
4427 to deliver the passphrase to the library.
4429 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4430 The public key verification and especially a certificate
4431 verification is asynchronous procedure.
4433 Added new SILC_SKE_STATUS_PENDING status to indicate the
4434 request is pending and a callback will be called to finalize
4437 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4438 indicate that remote end did not send its public key (or
4439 certificate), even though we require it. Added check for this
4440 condition in the SKE. This was a security bug, now fixed.
4442 Defined new SilcSKEVerifyCbCompletion callback that is called
4443 when the verification process is completed.
4445 The affected files lib/silcske/silcske_status.h and
4446 lib/silcske/silcske.[ch].
4448 * Changed the verify_public_key client operation to be async
4449 as well. Defined SilcVerifyPublicKey callback that is used to
4450 indicate the success of the public key verification process.
4452 Changed the server and client to use the new async client
4455 * Changed the Irssi SILC client's internal scheduler to be called
4456 twice as many times as it used to be. As a result the client
4457 should be a bit faster now. Affected file is
4458 irssi/src/silc/core/silc-core.c.
4460 * Added support to Irssi SILC client of asynchronous public key
4461 verification and passphrase inquiry. Affected file is
4462 irssi/src/silc/core/silc-core.c.
4464 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Do not say "You have left channel %s" in client library.
4467 Moved it to the application. Affected files are
4468 lib/silcclient/command.c and silc/client_ops.c.
4470 * Fixed silc_client_get_clients. Command context was not
4471 duplicated and was freed memory in the callback. Affected
4472 file lib/silcclient/idlist.c.
4474 * Do not say "you are now talking..." on JOIN command in the
4475 client library. The appliation must handle it.
4477 * Do not say ".. changed topic to" in command reply in the
4478 client libary. The application must handle it.
4480 * Fixed TOPIC command sending in the client library.
4482 * Fixed a memory leak in silc_client_command_free in the file
4483 lib/silcclient/command.c.
4485 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Imported a modified version of Irssi client to the source tree.
4488 The Irssi will be used to create a new client called
4489 Irssi SILC. Imported to irssi/.
4491 Added silc_core_init_finish function to the Irssi. Affected
4492 file irssi/configure.in.
4494 A lot changes in the Makefile.ams around the irssi tree.
4496 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Do not rehash if the new size is same as the old size of the
4499 hash table, in the silc_hash_table_rehash*. The affected file
4500 lib/silcutil/silchashtable.c.
4502 * Replaced hash_table_del_by_context calls from the server
4503 (when channel->user_list and client->channels) to the
4504 hash_table_del as it is sufficient and faster.
4506 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Added silc_hash_table_list, silc_hash_table_get and the
4509 SilcHashTableList structure to provide an alternative way to
4510 traverse the hash table. The affected files are
4511 lib/silcutil/silchashtable.[ch].
4513 * Changed the server's idlist routines to use the hash table
4514 routines to optimize the code.
4516 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * Replaced the client entry's `channel' list and channel entry's
4519 `user_list' list to hash tables for optimized lookup. Changed
4520 the code to use the hash table interface around the code.
4521 Affected file lib/silcd/idlist.[ch].
4523 * Added `auto_rehash' boolean argument to the function
4524 silc_hash_table_alloc to indicate whether the hash table should
4525 auto-rehash when it thinks is appropriate time. It will
4526 increase the hash table size if the there is twice as much
4527 entries in the table than the size of the table, and will
4528 decrease the size if there are twice as less entries than
4529 the size of the table.
4531 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4535 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * silc_idcache_purge_by_context deletes the entry now by context
4538 as it is supposed to do. Affected file lib/silccore/idcache.c.
4540 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4541 client is not anymore valid (WHOWAS givens the info) and not
4542 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4544 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4546 * Removed the `data' and `data_len' arguments from the ID Cache
4547 interfaces and added `name' argument. ID Cache does not handle
4548 anymore the binary data only a names associated with given ID.
4550 * When hashing a Client ID with silc_hash_id the entire ID is
4551 not hashed anymore, instead only the hash of the Client ID is
4552 hashed. This way we can access the Client ID from the cache
4553 with Client ID but with the hash of the ID (which is a hash of
4554 the nickname) as well without any difference in performance.
4556 Added also silc_idcache_find_by_id_one_ext to do one on one
4557 searching when we have the actual ID. Added also function
4558 silc_hash_client_id_compare. The affected files are
4559 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4561 * When hashing the name associated with a ID it is always done
4562 in lowercase. This way we can access the cache without worrying
4563 about case-sensitivity, even though, for example nicknames are
4566 * Fixed a bug in server with channel message sending. It put
4567 wrong ID type as destination ID. The affected file
4568 silcd/packet_send.c.
4570 * silc_idcache_del_by_context now deletes from all hash tables
4571 by context. Affected file lib/silccore/idcache.c.
4573 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Changed the client library to use the new ID Cache interface.
4576 Changes around the source tree.
4578 * Added silc_hash_table_rehash_ext to rehash with specific
4579 hash function. Affected file lib/silcutil/silchashtable.[ch].
4581 * Added silc_hash_string_compare to compare two strings in the
4582 hash table. Affected file lib/silcutil/silcutil.[ch].
4584 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Added new function silc_idcache_del_by_context into the
4587 lib/silccore/idcache.[ch].
4589 * Changed the server's ID list routines to use the new ID Cache
4590 interface. Changes around the source tree.
4592 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Added silc_hash_table_del[_by_context]_ext functions in to the
4595 lib/silcutil/silchashtable.[ch].
4597 Removed silc_hash_table_find_all* routines and added new
4598 silc_hash_table_find_foreach to replace them.
4600 Added silc_hash_table_replace_ext function as extended
4601 replacing function. Separated the simple hash table interface
4602 from the extended hash table interface in the file
4603 lib/silcutil/silchashtable.h.
4605 * Fixed minor bugs and changed it to use some of the new
4606 hash table functions in lib/silccore/idcache.c
4608 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Added new function silc_hash_table_find_all to return all keys
4611 in the hash table by the specified key. As the hash table is
4612 collision resistant it also makes it possible to have several
4613 duplicate keys in the hash table. This function may be used to
4614 find all of the keys from the hash.
4616 Added user_context arguments to the SilcHashFunction,
4617 SilcHashCompare and SilcHashDestructor to deliver user specified
4620 Added new fuctions silc_hash_table_find[_all]_ext to do
4621 extended lookup with specified hash and compare functions and
4622 specified user contexts.
4624 Added new function silc_hash_table_add_ext to add the key
4625 with specified hash function and user context.
4627 Added new function silc_hash_table_foreach to traverse all
4628 entrys in the hash table. Added SilcHashForeach callback
4631 Added new function silc_hash_table_del_by_context to delete
4632 the entry only if the context associated with the key matches.
4634 Affected files are lib/silcutil/silchashtable.[ch].
4636 * Removed silc_hash_[server/client/channel]_id and added just
4637 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4638 silc_hash_id_compare to compare two ID's using as the hash table
4639 comparison function. Added also silc_hash_data to hash
4640 binary data and silc_hash_data_compare to compare it.
4642 * Removed silc_idlist_find_client_by_hash as it is not needed
4643 anymore. Affected file silcd/idlist.[ch].
4645 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4646 to use internally the SilcHashTable. The new ID Cache is a lot
4647 faster than the old one. Some of the ID Cache interface was also
4648 rewritten and obsolete and stupid functions were removed.
4650 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Added entry_count field to the SilcHashTable to keep the number
4653 of the entries in the table. Implemented the function
4654 silc_hash_table_rehash. Added new function
4655 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4657 Fixed a minor bug in silc_hash_table_free.
4659 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4660 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4661 into the lib/silcutil/silcutil.[ch].
4663 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * Implemented a collision resistant hash table into the
4666 lib/silcutil/silchashtable[ch]. See the header and the source
4667 for the SilcHashTable API.
4669 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Merged dotconf version 1.0.2 into lib/dotconf.
4673 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Do not compile anything in lib/silcsim/* if the SIM support
4676 is not enabled. The tree should now compile without problems
4679 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Compiled the SILC under cygwin. Compiled and tested briefly
4682 without problems. More tests needed. The SIMs didn't compile
4685 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4687 * Fixed possible crash in silc_get_username in the
4688 lib/silcutil/silcutil.c.
4690 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4692 * Fixed a va_arg in silc/client_ops.c.
4694 * Oops, RC5 routines were named AES and caused some problems
4695 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4697 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * Added new SilcIDIP structure into the lib/silccore/id.h and
4700 replaced the old `ip' fields from all SILC ID's to that type.
4701 This is a step towards IPv6 support.
4703 The silc_id_get_len takes now the ID as an extra argument.
4704 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4705 both IPv4 and IPv6 based ID's.
4707 The affected files are lib/silccore/id.[ch] and other files
4708 around the tree using these routines.
4710 * Removed the ID length arguments in server from various
4711 silc_server_send_notify_* routines -> they are not needed
4714 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Fixed memory leak in silc_encode_pem_file in the file
4717 lib/silcutil/silcutil.c.
4719 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * Check minor version as well in the SKE. Affected files are
4722 silcd/protocol.c and lib/silcclient/protocol.c.
4724 * Added --identifier option to the server so that an identifier
4725 can be when creating the public key for the server. Affected
4726 file is silcd/silcd.c.
4728 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4729 lib/silccrypt/silcpkcs.c.
4731 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4733 * Register default ciphers and stuff when using -C option with
4734 the server. Affected file sildc/silcd.c.
4736 * Put back the servers public key filename format, it is better
4737 than the new one. For now, the client keys are saved with the
4738 new filename format. The affected file silc/client_ops.c.
4740 * Implemented the Cipher API for the rest of the ciphers that
4741 did not implement it or implemented it the wrong way.
4743 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * Register default ciphers and stuff when using the -S option
4746 in the client. Affected file silc/silc.c. Same also when
4747 creating new key pair with -C option.
4749 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Fixed the silc_verify_public_key client operation function to
4752 save the public keys differently. The fingerprint is now
4753 used as filename and not the hostname. This way also the
4754 client keys are saved uniquely and not with hostnames. The
4755 affected file is silc/client_ops.c.
4757 * Trimmed the silc_hash_fingerprint function to remove extra
4758 whitespaces from the end of the fingerprint. The affected
4759 file is lib/silccrypt/silchash.c.
4763 * Added silc_cipher_register_default function to register all
4764 default ciphers. It can be used when configuration files
4765 does not exist and the application does not want any specific
4766 ciphers in any specific order.
4768 The SilcDList is now used as silc_cipher_list dynamically
4769 allocated cipher list. Removed the static list all together
4770 and now all ciphers must be allocated to the dynamic list.
4771 The silc_cipher_alloc routine was changed to check only the
4774 All silc_cipher_* routines that used to return int returns
4777 The affected files lib/silccrypt/silccrypt.[ch].
4779 * The same thing was done to silc_hash_* as for silc_cipher_*
4780 routines. Affected files lib/silccrypt/silchash.[ch].
4782 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4783 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4784 Added also silc_pkcs_[un]register[_default] functions.
4785 Removed the data_context from the PKCS API.
4787 * Added silc_hmac_register_default function to register default
4788 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4789 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4790 to unregister all hmacs at once.
4792 * Register the default ciphers, hash functions, PKCSs and HMACs
4793 if client's configuration file does not exist. The affected
4796 * The client did not load the hash functions from the SIM
4797 modules at all. Added support for this. Affected file is
4798 silc/clientconfig.c.
4800 * When decoding public key with silc_pkcs_public_key_decode, check
4801 the supported algorithm only if PKCS are registered. Affected
4802 file lib/silccrypt/silcpkcs.c. The same was done with the
4803 silc_pkcs_private_key_decode.
4805 * Fixed the SILC List routines to keep the list always in order.
4806 It used to change the list's order when traversing the list but
4807 not it preserves the order. Affected file lib/trq/silclist.h.
4809 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Added the client library to use the SilcSocketConnection's
4812 reference counter (by silc_socket_dup) to prevent the bug that
4813 the socket object may be freed underneath async operation.
4815 * The name resolv library checking fixes in the configure.in.pre.
4818 * Created new version of the protocol drafts for future
4819 development. The -03 drafts are the ones that will be changed
4820 in the trunk now and the -02 will remain as they are.
4822 * Send list of CUMODE notifys to the router when announcing
4823 the channel users to the router. Affected file silcd/server.c.
4824 If the router receiving channel founder CUMODE for a channel
4825 that already has channel founder it will send CUMODE notify
4826 to the sender to remove the channel founder rights from the
4827 announced client. Affected file silcd/packet_receive.c.
4829 * The CUMODE notify may now use Server ID as well as the entity
4830 who changes the mode. Updated protocool specs.
4832 * Updated INSTALL and README files.
4834 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * New web pages in the http://silc.pspt.fi. The pages was
4841 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4843 * Implemented the [DenyConnectin] config section in the server.
4844 Added silc_server_config_denied_conn to check whether incoming
4845 connection is denied. Affected file silcd/serverconfig.[ch].
4847 * Do not check the ports when checking the incoming configuration
4848 data if the port is 0, meaning any. Affected file is
4849 silcd/serverconfig.c.
4851 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4853 * Fixed buffer overflow in silc_string_compare in the file
4854 lib/silcutil/silcutil.c.
4856 * Fixed double free in silc_server_command_leave in the file
4859 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4861 * Fixed the version checking in the server. Affected file is
4864 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4866 * Fixed the configuration data fetching when accepting new
4867 connections in the server. Affected file silcd/server.c.
4869 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Added `sender_entry' argument to the function
4872 silc_server_packet_relay_to_channel so that we can check
4873 whether some destination actually belongs to the same route
4874 the sender belongs (ie, we must not resend the packet to the
4875 sender). Affected file silcd/packet_send.[ch].
4877 * Added `servername' field to the SilcClientEntry in the server
4878 to hold the name of the server where client is from. Affected
4879 file is silcd/idlist.h.
4881 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Moved the channel message encrypting in the router betwen
4884 router connections from silc_server_channel_message to the
4885 silc_server_packet_relay_to_channel since we want to check
4886 whether we have anybody channel before encrypting anything.
4887 Affected files silcd/packet_[receive/send].c.
4889 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Fixed the [AdminConnection] server config section to support
4892 multiple entries. Affected file silcd/serverconfig.c.
4894 * Added support into the server to check the validity of the
4895 incoming connection before executing any KE or authentication
4898 * The connection configuration is now saved to the KE and
4899 connection auth protocol contexts and not fetched anymore in
4900 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4902 * The local hosts listenning address and port is also resolved
4903 now when starting the server. We want to have the socket object
4904 to include the real address and port for the listener. Added
4905 new function silc_net_check_local_by_sock into the files
4906 lib/silcutil/silcnet.[ch].
4908 * Fixed a broadcast bug in server -> do not broadcast if we
4911 * Fixed a routing bug. Do not route broadcast packets ever.
4912 Broadcast packets must be processed always and not routed since
4913 they may be destined to some other host than yourself and thus
4914 would get routed without no good reason. Affected file is
4917 * Added function silc_server_config_is_primary_route to check
4918 whether primary router connection has been configured (a router
4919 configuration that we are initiating). If there is not, we
4920 will assume that there is only two routers in the SILC network
4921 and we will use the incoming router connection as our primary
4922 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4924 * Changed the order of the broadcasting. Broadcast _after_ the
4925 packet has been processed not before. Affected file is
4928 * Fixed a [ClientConnection] parsing bug. The port was never
4929 parsed correctly thus resulting to port 0. Affected file
4930 silcd/serverconfig.c.
4932 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4933 argument and did not set the broadcast packet flag. Affected
4934 file silcd/packet_send.c. Fixed same bug in the function
4935 silc_server_send_notify as well.
4937 * If we receive NEW_ID packet for our own ID in the server, ignore
4940 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4944 * Removed the nickname from the Private Message Payload.
4945 Updated the code and the protocol specs.
4947 * Updated protocol specs for submitting to the IETF.
4949 * Tweaked the Random Number Generator a bit. Affected file
4950 lib/silccrypt/silcrng.c. Exported a new function
4951 silc_rng_[global]_add_noise which can be used to add more
4954 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Do not parse packets with different timeout when protocol
4957 is active -> may cause problem with rekey. Affected file
4960 * When server receives signoff notify it must not create
4961 new channel key if the client is on any channels since the
4962 sender of the signoff notify will create it.
4964 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Added printing of error messages during SKE protocol from the
4967 failure packet sent by server during SKE. Affected file
4970 * Removed the client's failure_callback handling with timeout
4971 and handle it immediately when received.
4973 * The SKE library returned wrong type in SUCCESS and FAILURE
4974 packets. They must be 32 bit MSB not 16 bit MSB.
4976 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Ok, rewrote the logic of the re-key and now it seems to work.
4979 I tested it on high traffic with frequent re-keys without
4980 problems. Added hmac_receive (and renamed hmac to hmac_send)
4981 in SilcClientConnection in lib/silcclient/client.h and
4982 in SilcIDListData in silcd/idlist.h. Also, removed the
4983 SilcPacketParserContext's cipher and hmac fields as they are
4984 not needed anymore and actually caused some problems when
4985 the ciphers and hmac's changed underneath the packet parser.
4987 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * If re-key protocol is active then process the incoming packets
4990 synchronously since we must assure that icoming packets encrypted
4991 with the old key is processed before the new keys is set to
4992 use. This is true other packets than for REKEY packets.
4993 Affected file silcd/server.c. The same was done to client library
4994 as well, affected file lib/silcclient/client.c.
4996 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4998 * Fixed bug in client and server to accept the force send if
4999 the packet is send from silc_[server/client]_packet_process
5000 function. Otherwise the packets are never delivered, oops.
5002 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Disable force sending of packets when REKEY protocol is active.
5005 We must assure that no packet is sent directly when rekey is
5006 performed. All packets must be sent through packet queue.
5007 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5008 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5009 function is silc_[server/client]_packet_send_real to check
5012 * Replaced the SIM paths from example config files to
5013 /usr/local/modules. Also, make install creates now
5014 /usr/local/silc/logs directory to hold all the SILC server
5017 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Made the configure.in.pre work on Solaris. Patch by salo.
5021 * Made all ciphers compatible with non-x86 machines. Defined
5022 CBC mode macros into lib/silccrypt/ciphers_def.h.
5024 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Fixed the make install.
5028 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * When MAC computation fails the silc_packet_decrypt returned 0
5031 even though it was supposed to return -1. Fixed this. The
5032 affected file is lib/silccore/silcpacket.c.
5034 * Do not replace the config files in /etc/silc (in make install)
5035 if they already exist. Affected file ./Makefile.am.
5037 * Do not send re-key packets immediately but through packet queue.
5038 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5040 * Changed silc_net_check_host_by_sock to return FALSE if the
5041 IP/DNS could not be resolved. Though, it returns the IP address
5042 now even if it could not resolve it (but returns also FALSE).
5043 Affected file lib/silcutil/silcnet.[ch].
5045 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Added silc_pkcs_decode_identifier to decode the public key's
5048 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5049 Added also silc_pkcs_free_identifier. Added also new context
5050 SilcPublicKeyIdentifier.
5052 * Added -S option to the silc client. It is used to dump the
5053 contents of the specified public key file.
5055 * Changed the PKCS api to return the public key length when
5056 setting the public key.
5058 * Fixed a fatal bug in the public and private key file loading.
5059 Affected file lib/silccrypt/silcpkcs.c.
5061 * Execute the packet parsing for client with zero (0) timeout
5062 if the protocol is active. Affected file silcd/server.c.
5064 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Made the key generation options to the silcd program. Added
5067 -C option, equivalent to client's option.
5069 * Added new [ServerKeys] config section to the server. It
5070 configures the server's public and private key.
5072 * Defined generic Public Key Payload into the protocol
5073 specification to send specific type of public keys and
5076 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5077 public key or certificate.
5079 * Implemented the GETKEY command to the server and to the
5080 client library and on user interface.
5082 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Made preliminary `make install' work.
5086 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Added SilcServerRekey context into silcd/idlist.h.
5090 * Added the PFS support as defined in the specification to the
5091 SKE protocol. Affected files lib/silcske/*.c.
5093 * Added `ske_group' field to the SilcServerRekey context to hold
5094 the number of the SKE group that is used with PFS in re-key.
5095 Affected file silcd/idlist.h.
5097 * Added PFS re-key support to the server. Affected file is
5100 * Added silc_protocol_cancel to cancel execution of the next
5101 state of the protocol. Affected file is
5102 lib/silccore/silcprotocol.[ch].
5104 * Added the re-key support with and without PFS to the client
5105 library. Re-key is performed once in an hour, by default.
5107 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5108 Added silc_client_rekey_callback and silc_client_rekey_final.
5109 Affected files are lib/silcclient/protocol.[ch] and
5110 lib/silcclient/client.[ch].
5112 * Removed the `hmac_key' and `hmac_key_len' fields from the
5113 SilcClientConnection structure; not needed. Affected file is
5114 lib/silcclient/client.h.
5118 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5120 * Do not ask whether user wants to use the negotiated private key
5121 for private messages, just use it. Affected file is
5122 silc/local_command.c.
5124 * Added `send_enc_key' and `enc_key_len' fields to the
5125 SilcIDListData structure since they are needed in the re-key
5126 phase. Affected file is silcd/idlist.[ch].
5128 * Implemented the simple re-key protocol into the server.
5129 Affected files silcd/server.c and silcd/protocol.[ch]. The
5130 re-key will be performed once in an hour, by default.
5132 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.

5136 * Removed Tunneled flag from the protocol. Updated the code
5137 and the specifications.
5139 * Adde `pfs' field to the SilcIDListData to indicate whether
5140 the PFS is to be performed in the re-key. Affected file is
5143 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5146 int64 of at least the xintXX size. If void * is less that 4
5147 bytes uint32 * will be used. Defined bool as boolean.
5149 * Changed _ALL_ unsigned long and unsigned int to uint32,
5150 unsgined short to uint16 in the source tree.
5152 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5153 not handle clients that has entry->data.registered == FALSE.
5154 They are not in the network anymore. Affected file is
5157 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Implemented the sending of the SERVER_SIGNOFF notify in the
5160 server. Affected file is silcd/server.c.
5162 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5163 Added also silc_notify_payload_encode_args into the
5164 lib/silccore/silcnotify.[ch].
5166 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5167 Affected file silcd/packet_receive.c.
5169 * Implemented the SERVER_SIGNOFF notify handling in the client
5170 library. Affected file lib/silcclient/client_notify.c. Also,
5171 implemnted the printing of the SERVER_SIGNOFF info to the
5172 application. Affected file silc/client_ops.c.
5174 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5175 if the deleting was successful. Affected file silcd/idlist.[ch].
5177 * Added support for public key authentication in the connection
5178 authentication protocol in the client library. Affected file
5179 lib/silcclient/protocol.c.
5181 * Changed the server's silc_idlist_get_clients_by_* interface
5182 to support already allocated array so that new entries may be
5183 added to pre-allocated array. Affected file silcd/idlist.[ch].
5184 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5185 and command replies.
5187 * All command reply functions in the server now calls the
5188 pending command callback even if error occured. This way the
5189 error will be delivered to the client as well. Affected files
5190 silcd/command.c and silcd/command_reply.c.
5192 * Fixed INFO command to return local server's info if no server
5193 was provided. Affected file lib/silcclient/command.c.
5195 * Removed RESTART command for good. Updated the code and the
5198 * Rewrote parts of the task system. It is a bit simpler now.
5199 Removed unsued task priorities. The affected files are
5200 lib/silcutil/silctask.[ch].
5202 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Moved the USERS printing from the library to the application.
5205 Affected files lib/silcclient/command.c and silc/client_ops.c.
5207 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Added channel key re-key support. The re-key is perfomed
5212 only by the router and is done once in an hour. Added `rekey'
5213 field to the SilcChannelEntry in the server. Affected files
5214 silcd/server.c and silcd/idlist.h.
5216 * Added silc_task_unregister_by_context into the file
5217 lib/silcutil/silctask.[ch].
5219 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Added SILC_UMODE_GONE mode to indicate when the client is not
5222 present in the SILC network. Added also support to the local
5223 command AWAY that will set this mode. Added support of showing
5224 "xxx is gone" in WHOIS command. The USERS command shows the
5225 gone status as well.
5227 * Fixed setting server and router operator privileges in the
5228 server's UMODE command. Affected file silcd/command.c.
5230 * Merged the SKE KE1 and KE2 payloads into one payload. The
5231 new KE payload is equivalent to the old KE2 payload.
5233 Cleaned up the SKE Start Payload parsing. It now uses the
5234 simple buffer unformatting to do the parsing. A lot faster
5237 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5238 to the SKE that is used to indicate whether both of the SKE
5239 parties should perform authentication. By default only the
5240 responder performs authentication. By setting this flag also
5241 the initiator must do authentication. By default it is unset
5242 since in normal SKE case, client to server connection, only
5243 the responder should do authentication. When doing SKE between
5244 two clients both should perform authentication. Updated the
5245 code and the protocol specs.
5247 * A little fix to IDENTIFY command in the server. Search the
5248 client first by hash not nickname. Affected file is
5251 * Fixed the silc_client_close_connection to support closing
5252 the client to client connections wihtout deleting too much
5253 data. Affected file lib/silcclient/client.c.
5255 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5256 are received if protocol used to be active but is not anymore
5257 the application would crash due to NULL pointer dereference.
5258 Affected files silcd/server.c and lib/silcclient/client.c.
5260 * Added `hash' field to the SilcClientConnection to include
5261 the hash function negotiated in the SKE protocol.
5263 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5264 to set the channel founder authentication data. A client can
5265 claim the founder rights later by providing the authentication
5266 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5267 This way the channel founder can regain the channel founder
5268 privileges even it is left the channel. This works only on
5269 local server and the client must be connected to the same
5270 server to be able to regain the founder rights. Updated the
5271 protocol specs accordingly.
5273 Added support to the CMODE command in the client to set the
5274 founder auth data. Read the README to see how to set it.
5276 Added support to the CUMODE command to claim the founder
5277 rights. Read the README to see how to do it.
5279 Added support for the founder authentication to the Channel
5280 Entry in the server. Affected file silcd/idlist.h.
5282 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5283 server's CMODE command. Affected file silcd/command.c.
5285 * Added the following new functions into lib/silccore/silcauth.[ch]:
5286 silc_auth_get_method and silc_auth_get_data.
5288 * The server now saves the remote hosts public key to the
5289 SilcIDListData pointer. Affected file silcd/protocol.c.
5291 * The normal server now does not remove the channel entry from
5292 the cache if the founder authentication data is set. It used
5293 to remove it if the founder was the last one on the channel on
5294 the server and left the channel. The auth data is saved and
5295 if the channel is re-joined later the old entry is used with
5296 the old auth data. Affected files silcd/command_reply.c and
5299 * Removed the `pkcs' field from the SilcIDListData structure
5300 in the server; it is not used. Affected file silcd/idlist.h.
5302 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Fixed packet processing on slow links. Partial packets were
5305 never re-processed because the incoming data buffer was cleared
5306 by the application. Application must not directly clear the
5307 sock->inbuf, the packet processing routines handle it. Fixed
5308 this in client library and in server.
5310 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Fixed the WHOIS and IDENTIFY send reply function to really
5313 check whether to send list or just one entry. Affected file
5316 * Cleaned up the LEAVE command's channel key distribution. The
5317 affected file silcd/command.c.
5319 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5320 can enforce the channel mode as well. In that case the ID
5321 includes the ID of the server. The code now enforces the
5322 mode change if the router have different mode than the server.
5324 * The notify client operation with CMODE_CHANGE notify can now
5325 return NULL client_entry pointer if the CMODE was not changed
5326 by client. Application must check for this.
5328 * Added <Server ID> argument to INFO command to support server
5329 info fetching by Server ID.
5331 * Added silc_server_announce_get_channel_users to get assembled
5332 packets of channel users of the specified channel. Affected
5333 file silcd/server.[ch].
5335 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5336 was freed underneath the ID Cache.
5338 * Re-announce clients when the server received CHANNEL_CHANGE
5339 notify from the router. Affected file silcd/packet_send.c.
5341 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5344 crashed since it did not handle the fact that there is no cipher
5345 called "3" and didn't check the error condition. Now fixed.
5347 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5348 flag. It can be used to send message requests.
5350 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Implemented the RESTART command in the client.
5354 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5355 notice type messages. Added notice printing to the user
5358 * The channel keys are not re-generated if the channel's mode
5359 is PRIVKEY, ie private key on the channel exists. Affected
5360 files silcd/server.c and silcd/command.c.
5362 * Fixed a little bug in channel message delivery when channel
5363 private keys are set in the server. Affected file is
5364 silcd/packet_send.c.
5366 * Changed the setting on channel->on_channel = TRUE from the
5367 silc_client_save_channel_key to the JOIN command reply. The
5368 key payload is not received if the private channel key is set.
5369 Affected file lib/silcclient/command_reply.c and the
5370 lib/silcclient/client_channel.c.
5372 * When the CMODE_CHANGE notify is sent and the channel private
5373 key mode is removed the channel key must be re-generated in
5374 other cells as well. Added this support for the router in the
5375 silcd/packet_receive.c.
5377 * Added new local command NOTICE to send notice message on
5378 channel. Affected file silc/local_command.[ch].
5380 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Added new local command ME to the client. It is used to send
5383 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5384 some action. Affected file silc/local_command.[ch].
5386 * Changed channel_message and private_message client operations
5387 to deliver the message flags to the application. Added also
5388 the `flags' arguments to the silc_client_send_channel_message
5389 and silc_client_send_private_message functions. Affected file
5392 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Redefined the Private Message Payload to support private message
5395 keys and to support the new private message flags. Updated
5396 the protocol specs. Flags makes it possible to have for example
5397 CTCP style messages.
5399 * Added new type SilcPrivateMessagePayload and defined an API
5400 for it in the lib/silcclient/silcprivate.[ch].
5402 * Tested private message private keys successfully. Tested the
5403 private message key set, unset and list commands with the new
5406 * Redefined the Channel Message Payload to include the channel
5407 message flags (equal with private message flags) to support
5408 for example CTCP style messages.
5410 * Defined some of the message (for channel and private message)
5411 flags. Updated the protocol specs and added the flags to the
5412 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5414 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Added SilcKeyAgreementStatus type to the key agreement routines
5417 to indicate the current status and error if one occured.
5418 The status types are defined in the lib/silcclient/silcapi.h.
5420 * Added new local command KEY that is used to set and unset private
5421 keys for channels, set and unset private keys for private messages
5422 with remote clients and to send key agreement requests and
5423 negotiate the key agreement protocol with remote client. The
5424 key agreement is supported only to negotiate private message keys,
5425 it currently cannot be used to negotiate private keys for channels,
5426 as it is not convenient for that purpose.
5428 * Fixed a minor pending callback setting bug in the function
5429 silc_client_get_client_by_id_resolve, now the function works.
5430 Affected file lib/silcclient/idlist.c.
5432 * Added function silc_net_get_local_port to get local bound
5433 port by socket. Added to lib/silcutil/silcnet.[ch].
5435 * Added `sockets' and `sockets_count' fields to the SilcClient
5436 object. They hold the sockets of the listenning sockets in
5437 the client. Listenning sockets may be for example the key
5438 agreement server. Affected file lib/silcclient/client.[ch].
5439 Added functions the silc_client_add_socket and the
5440 silc_client_del_socket. They are exported to the application
5443 * Added ~./silc/clientkeys to support other client's public keys.
5445 * Renamed verify_server_key client operation to verify_public_key
5446 and added one argument to indicate the type of the connection
5447 (server, client etc.).
5449 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5451 * Added silc_server_connection_auth_request to handle the
5452 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5453 silcd/packet_receive.[ch].
5455 * Added silc_server_send_connection_auth_request into the
5456 silcd/packet_send.c to send the connection auth request packet.
5458 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5461 * Fixed the public key authentication in responder side in the
5462 server. The `auth_data' pointer includes the SilcPublicKey
5463 not the path to the public key. Affected file silcd/protocol.c.
5465 * Implemented the public key authentication in the initiator side
5466 in the server. Affected file silcd/protocol.c.
5468 * Removed the [RedirectClient] config section from the server
5469 configuration. Is not needed and I don't want to implement it.
5471 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Cleaned up the CMODE command in the server. It now works
5474 correctly and supports all the modes defined in the protocol.
5475 Affected file is silcd/command.c.
5477 * Added `hmac_name' field to the SilcChannelEntry in the server
5478 to hold the default HMAC of the channel. It can be set when
5479 creating the channel (with JOIN command). Affected files
5482 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5483 type to indicate the change of the current cipher and hmac
5484 on the channel. Client can safely ignore the <cipher> argument
5485 (if it chooses to do so) since the CHANNEL_KEY packet will
5486 force the channel key change anyway. The <hmac> argument is
5487 important since the client is responsible of setting the new
5488 HMAC and the hmac key into use.
5490 * Fixed the CMODE command in the client library as well.
5492 * Tested CMODE command in router environment successfully.
5494 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Show the version of the remote client (or server) when connecting
5497 to the server. It is logged to the log file. Affected file
5498 is silcd/protocol.c.
5500 * Fixed the KILLED notify handling in the client library. The
5501 client must be removed from all channels when receiving the
5504 Also, do not remove the client entry when giving the KILL
5505 command but when the KILLED notify is received.
5507 * Removed silc_idlist_find_client_by_nickname from the server.
5508 Not needed anymore. Affected files silcd/idlist.[ch].
5510 * Implemented the CHANNEL_CHANGE notify type handling to the
5511 server. Affected file silcd/server.c.
5515 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Added silc_server_send_notify_invite to send the INVITE
5518 notify between routers.
5520 * Implemented the INVITE command correctly to the server.
5522 * Implemented the INVITE notify type handling in the server.
5524 * Implemented the INVITE command to the client library and on the
5527 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Added function silc_server_get_client_resolve to find the
5530 client entry by ID from all ID lists and then resolve it
5531 (using WHOIS) if it cannot be found. Affected file is
5534 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Implemented the BAN command to the client library.
5538 * The JOIN command in the server now checks the invite list
5541 * Changed the silc_command_reply_payload_encode_va and the
5542 silc_command_payload_encode_va to support that if argument is
5543 NULL it ignores and checks the next argument. Affected file
5544 lib/silccore/silccommand.c.
5546 * Added silc_server_send_notify_ban to send the BAN notify
5547 type between routers.
5549 * Chaned the silc_notify_payload_encode to support that if
5550 argument is NULL it ignores and checks the next argument.
5551 Affected file lib/silccore/silcnotify.c.
5553 * Tested ban lists in router environment successfully.
5555 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Implemented BAN command to the server, in silcd/command.[ch].
5559 * Removed the BAN and INVITE_LIST modes from the CMODE command
5562 * Added function silc_string_match to regex match two strings.
5563 Affected files lib/silcutil/silcutil.[ch].
5565 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5567 * Redefined parts of the SilcChannelEntry in the server to support
5568 the new ban and invite lists.
5570 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Redefined the INVITE command. The same command can be used to
5573 invite individuals to the channel but also to manage the invite
5574 list of the channel (to add to and remove from the invite list).
5575 Updated the protocol specs.
5577 * Added new command SILC_COMMAND_BAN that can be used to manage
5578 the ban list of the channel. Updated the protocol specs.
5580 * Removed the channel modes: the SILC_CMODE_BAN and the
5581 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5582 in the CMODE command. The equivalent features are now available
5583 using INVITE and BAN commands. Updated the protocol specs.
5585 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5586 in the network about change in the current ban list. The notify
5587 type is not used by the client.
5589 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5590 support the invite lists.
5592 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Added new function silc_string_regexify that converts string
5595 including wildcard characters into regex string that can
5596 be used by the GNU regex library. Added into the file
5597 lib/silcutil/silcutil.[ch].
5599 Added silc_string_regex_combine to combine to regex strings
5600 into one so that they can be used as one regex string by
5601 the GNU regex library. Added into the file
5602 lib/silcutil/silcutil.[ch].
5604 Added silc_string_regex_match to match two strings. It returns
5605 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5607 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Imported GNU regex to the soruce tree into lib/contrib.
5610 Fixed some compiler warning from the regex.c.
5612 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Fixed MOTD command in the server to work in router environment.
5616 * Fixed the MOTD command in the client library to support
5617 the server argument in the command.
5619 * Added `nickname_len' argument to the silc_idlist_add_client
5620 in the server, as the `nickname' argument may be binary data
5623 * Added silc_idlist_get_channels to return all channels from
5626 * Implemented LIST command to the server. Affected file is
5629 * Implemented the LIST command to the client library and on the
5632 * Added [<user count>] argument to the LIST command reply.
5633 With private channels the user count is not shown.
5635 * Updated TODO and README.
5637 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * The client entry's data.registered must be TRUE even with
5640 global client entry on global client list. The data.registered
5641 is used to check whether the client is anymore in the network,
5642 for example with WHOWAS command so it must be valid.
5644 * Fixed the WHOWAS command in the server. It now actually works
5645 in router environment. Added function into silcd/command_reply.c
5646 silc_server_command_reply_whowas_save.
5648 * Added silc_idlist_purge function to the silcd/idlist.c
5649 to periodically purge the ID Cache.
5651 * Fixed INFO command in the server. It works now in router
5652 environment. Added <server name> argument to the INFO command
5653 reply. Updated the protocol specs.
5655 * Fixed minor bug in silc_idcache_purge to not purge if the
5656 expire value is zero.
5658 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5659 they were buggy because of the WHOWAS information.
5661 * Fixed local command MSG to handle the async resolving of
5662 the remote client properly. It used to fail the first MSG.
5663 Affected file silc/local_command.c.
5665 * Added `data_len' field to SilcIDCache context.
5667 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Update TODO. Todo in commands in the server.
5671 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5674 used by routers as broadcast packet to inform other routers
5675 about the changed user mode.
5677 Implemented the notify handling in the server. Affected file is
5678 silcd/packet_receive.c. Added the function
5679 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5681 * Added new generic Channel Payload and deprecated the New Channel
5682 Payload. The New Channel Payload is now the generic Channel
5685 * Added new argument `mode' to the silc_server_send_new_channel
5686 as it is required in the Channel Payload now.
5688 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5689 and created a new and real SilChannelPayload to represent the
5690 new generic Channel Payload. Implemented the encode/decode
5691 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5693 * Added silc_server_get_client_channel_list to return the list
5694 of channels the client has joined for WHOIS command reply.
5695 Affected file silcd/server.[ch].
5697 * Implemented the channel list sending in the WHOIS command reply
5698 in server and in the client.
5700 Implemented the channel list displaying on the user interface
5701 as well. Affected file silc/client_ops.c.
5703 * Added silc_channel_payload_parse_list to parse list of Channel
5704 Payloads. It returns SilcDList list of SilcChannelPayloads.
5705 Client for example can use this function to parse the list of
5706 channels it receives in the WHOIS command reply. The caller
5707 must free the list by calling silc_channel_payload_list_free.
5708 Affected files lib/silccore/silcchannel.[ch].
5710 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5712 * Added one new argument <user mode> to the WHOIS command reply
5713 to return the mode of the user in SILC. Updated the protocol
5716 Implemented it to the server and client.
5718 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Fixed the mode printing on the user interface on joining.
5721 Affected file silc/client_ops.c.
5723 * Implemented the UMODE command and user modes in general to the
5724 client library and to the user interface.
5726 * Implemented the UMODE command to the server.
5728 * The server now sends UNKNOWN_COMMAND error status if client sends
5729 unknown command. Affected file silcd/command.c.
5731 * All server commands now handle the command identifier the right
5732 way when sending the command reply to the client. The client can
5733 use to identify the command replies with the identifier.
5735 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Added silc_server_get_client_route to resolve the route to
5738 the client indicated by the client ID. Affected file is
5741 * Added silc_server_relay_packet as general function to relay
5742 packet to arbitrary destination. This deprecates functions
5743 like _send_private_message_key, _relay_notify etc. Affected
5744 file is silcd/packet_send.[ch].
5746 Removed silc_server_send_key_agreement,
5747 silc_server_send_private_message_key and
5748 silc_server_packet_relay_notify functions from the file
5749 silcd/packet_send.[ch].
5753 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5754 server. Affected file silcd/packet_receive.[ch].
5756 * Implemented the KILL command to the client. Implemented the
5757 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5758 Affected files lib/silcclient/command[_reply].c and
5759 lib/silcclient/client_notify.c. Implemented the KILL notify
5760 printing in the user inteface.
5762 * Fixed a lot silc_parse_nick memory leaks from the client
5763 library in the file lib/silcclient/command.c.
5765 * Changed the silc_server_send_notify_on_channels's `sender'
5766 argument from SilcSocketConnection to SilcClientEntry to
5767 check the sender as entry and not as connection object and not
5768 to send to the client provided as argument. The affected file
5769 is silcd/packet_send.[ch].
5771 * The notify packets that are destined directly to the client used
5772 to not to be processed by the server. Now changed that and the
5773 server processes all notify packets. After relaying the packet
5774 to the client the notify packet is processed in the server.
5776 * The silc_server_free_client_data now checks whether there is
5777 pending outgoing traffic for the client and purges the data to
5778 the network before removing the client entry.
5780 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5783 an client is killed from the SILC Network. Updated the protocol
5786 Added new function silc_server_send_notify_killed to the
5787 silcd/packet_send.[ch].
5789 * Added function silc_server_packet_relay_notify to relay notify
5790 packets that are destined directly to a client. In this case
5791 the server does not process the notify packets but merely relays
5792 it to the client. Affected file silcd/packet_send.[ch].
5794 Added also silc_server_packet_process_relay_notify to check
5795 whereto relay the notify. Affected file is
5796 silcd/packet_receive.[ch].
5798 * Implemented the KILL command to the server.
5802 * Added the backup schema desgined last fall to the protocol
5803 specs for everyone to see. The specification is in the
5804 *-spec-xx.txt draft and the packet type definitions for the
5805 backup routers is in *-pp-xx.txt draft. Thusly, added also
5806 new packet type SILC_PACKET_CELL_ROUTERS.
5808 * A big security problem in the implementation discovered. The
5809 signoff of an client did not cause new channel key generation
5810 which it of course should've done. The channel keys must be
5811 always re-generated when client leaves (or signoffs) the channel.
5812 The silc_server_remove_from_channels funtion now handles
5813 the channel key re-generation.
5815 * Added `sender' argument to the silc_server_send_notify_on_channels
5816 to not to send the client provided as argument. Affected file
5817 silcd/packet_send.[ch].
5819 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Implemented OPER and SILCOPER commands into the server and
5824 * Added silc_auth_verify and silc_auth_verify_data to verify
5825 the authentication directly from the authentication payload.
5826 It supports verifying both passphrase and public key based
5827 authentication. Affected file lib/silccore/silcauth.[ch].
5829 * Added `hash' field to the SilcIDListData structure. It is the
5830 hash negotiated in the SKE protocol. Affected file is
5833 * Slight redesigning of the SilcAuthPayload handling routines.
5834 Do not send SilcPKCS but SilcPublicKey as argument.
5836 * Implemented the public key authentication support to the
5837 serverconfig. The public key is loaded from the provided path
5838 and saved as authentication data to void * pointer. Thus,
5839 changed the unsigned char *auth_data to void *auth_data;
5841 * Fixed SHUTDOWN command to send the reply before the server
5842 is shutdown. :) Affected file silcd/command.c.
5844 * Fixed fatal bug in CONNECT command. The hostname was invalid
5845 memory and server crashed. Affected file silcd/command.c.
5847 * Fixed fatal bug in CLOSE command. The server_entry became
5848 invalid but was referenced later in the command. Affected file
5851 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Fixed fatal bug in failure packet handling. Server ignored
5854 the failure and thus crashed when it came.
5858 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5860 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5861 that the command may be executed only once in (about) 2 seconds.
5862 The old SILC_CF_LAG flag is same but allows command bursts up
5863 to five before limiting.
5865 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5866 server code. Various commands now includes the CF_LAG_STRICT
5867 flag to disallow any kind of miss-use of the command.
5869 * Fixed the silc_buffer_unformat to not to allocate any data
5870 if the length of the data is zero. It used to allocate the
5871 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5873 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Changed the format of AdminConnection configuration section
5876 in the server. Added username of the admin to the format.
5877 Affected files silcd/serverconfig.[ch].
5879 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5880 to return admin configuration data by host, username and/or
5883 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Implemented WHOWAS command to the server. Added the functions:
5887 silc_server_command_whowas_parse,
5888 silc_server_command_whowas_send_reply,
5889 silc_server_command_whowas_from_client and
5890 silc_server_command_whowas_from_server
5892 * Added <Client ID> argument to the WHOWAS command reply. Updated
5893 the protocol specs accordingly.
5895 * Implemented WHOWAS command and command_reply to the client
5898 Implemented the WHOWAS printing on the user interface.
5900 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Added new argument to the WHOWAS command reply, the real name.
5903 It is an optional argument. Updated the protocol specs.
5905 * Added SilcIDCacheDestructor callback that is registered when
5906 the SilcIDCache is allocated. The callback is called when
5907 an cache entry in the ID Cache expires, or is purged from the
5908 cache. Added into lib/silccore/idcache.[ch].
5910 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5911 to destruct the client entries when the cache entry expires.
5912 Other ID Cache's in server and in the client library ignores
5915 * If the ID Cache entry's `expire' field is zero then the entry
5916 never expires. Added boolean `expire' argument to the
5917 silc_idcache_add function in the lib/silccore/idcache.[ch].
5918 If it is TRUE the default expiry value is used.
5920 * Added silc_server_free_client_data_timeout that is registered
5921 when client disconnects. By default for 5 minutes we preserve
5922 the client entry for history - for WHOWAS command.
5924 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Added support to the server to enforce that commands are not
5927 executed more than once in 2 seconds. If server receives
5928 commands from client more frequently, timeout is registered
5929 to process the commands. Affected file silcd/command.c.
5930 Added new function silc_server_command_process_timeout.
5932 * Changed NICK_NOTIFY handling in client library to check that
5933 if the client's nickname was changed, so there is no need to
5934 resolve anything from the server.
5936 * Removed error printing from the WHOIS and IDENTIFY commands.
5937 If error occurs then it is ignored silently in the client library.
5938 The application, however, may map the received error to
5939 human readable error string. The application currently maps
5940 the NO_SUCH_NICKNAME error to string.
5942 * Made the command status message public to the application. Moved
5943 them from lib/silcclient/command_reply.c to
5944 lib/silcclient/command_reply.h. The application can map the
5945 received command status to the string with the
5946 silc_client_command_status_message function.
5948 * Added check to the server to check that client's ID is same
5949 as the Source ID in the packet the client sent. They must
5952 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Added dist-bzip hook to the Makefile.am to make bzip2
5955 compressed distributions.
5957 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Server now enforces the maximum length for the nickname and
5960 the channel as protocol specification dictates. 128 bytes for
5961 nickname and 256 bytes for channel name.
5963 * Moved the WHOIS printing to the application. The client libary
5964 does not print out the WHOIS information anymore, the application
5965 must do it. Renamed silc_client_command_reply_whois_print to
5966 the silc_client_command_reply_whois_save.
5968 The client's idle time is also sent to the application now, and
5969 the idle is shown on screen.
5971 * Added silc_client_command_reply_identify_save to save the
5972 received IDENTIFY entries.
5974 * Do not check for channel private keys in message sending and
5975 reception if the channel does not have the PRIVKEY mode set.
5976 Affected file lib/silclient/client_channel.c.
5978 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5981 just surfaced after chaning the JOIN procedure.
5983 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Added silc_client_get_clients_by_list to get client entries
5986 from Client ID list, that is returned for example by JOIN
5987 and USERS command replies. The application should use this
5988 function for example when JOIN command reply is received to
5989 resolve the clients already on the channel (library does not
5990 do that anymore as USERS command reply is not used in the JOIN
5991 procedure anymore). Affected files lib/silcclient/silcapi.h and
5992 lib/silcclient/idlist.c.
5994 * JOIN command reply and USERS command reply returns now SilcBuffer
5995 pointers instead of unsigned char pointers when returning
5996 the client list and mode list.
5998 * Added <Client ID> argument to the JOIN command reply, mainly
5999 for the server to identify for which client the command was
6000 originally sent. Updated protocol specs accordingly.
6002 * Added SilcDlist private_key pointer to the SilcChannelEntry
6003 in the client to support the channel private keys. Affected
6004 file is lib/silcclient/idlist.h.
6006 * Added SilcChannelPrivateKey argument to the function
6007 silc_client_send_channel_message so that application can choose
6008 to use specific private ke if it wants to. If it is not provided,
6009 the normal channel key is used, unless private keys are set.
6010 In this case the first (key that was added first) is used
6011 as the encryption key.
6013 * Implemented the support for channel private key handling.
6014 Implemented the following functions:
6016 silc_client_add_channel_private_key,
6017 silc_client_del_channel_private_keys,
6018 silc_client_del_channel_private_key,
6019 silc_client_list_channel_private_keys and
6020 silc_client_free_channel_private_keys
6022 Affected file lib/silcclient/client_channel.c.
6024 * Added the support for the private keys in the channel message
6025 sending and encryption and in the message reception and
6026 decryption. Affected funtions are
6027 silc_client_send_channel_message and silc_client_channel_message.
6029 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6031 * Added SKE's key verify callback to the client library's
6032 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6034 * Removed the statement that server (or router) must send USERS
6035 command reply when joining to the channel so that the client
6036 knows who are on the channel. Instead, the client list and
6037 client's mode list is now sent in the JOIN command reply to the
6038 client who joined channel. This is better solution.
6040 * Added function silc_server_get_users_on_channel and function
6041 silc_server_save_users_on_channel to the silcd/server.[ch].
6043 * Removed function silc_server_command_send_users from the
6046 * Do not show topic on the client library anymore. The topic is
6047 sent in the command reply notify to the application and the
6048 application must show the topic now.
6050 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Added client searching by nickname hash into the IDENTIFY and
6053 WHOIS commands in the server as they were clearly missing from
6054 them. Affected file is silcd/command.c.
6056 * Fixed a bug in private message receiving in the client library.
6057 The remote ID was freed and it wasn't supposed, now it is
6060 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6062 * Minor fix to the channel payload; allocate the data area, as it
6063 needs to be of specific length.
6065 * If the key agreement port is zero then the operating
6066 system will define the bound port. Affected files are
6067 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6069 * Added new function silc_channel_payload_decrypt into the file
6070 lib/silccore/silcchannel.[ch].
6072 * Moved the channel message etc, check from silc_packet_decrypt
6073 to applications. The library calls now a generic
6074 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6075 when the packet is either normal or special. This was done to
6076 allow more wide range of checking that was not allowed when
6077 the code was in library. Now applications can do virtually any
6078 checks to the packet and return to the library the decision how
6079 the packet should be processed. Affected files are
6080 lib/silccore/silcpacket.[ch].
6082 Added silc_server_packet_decrypt_check to the server and
6083 silc_client_packet_decrypt_check to the client library.
6085 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6086 to send with specified source and destination information.
6088 * Channel message delivery between routers was broken after the
6089 channel key distribution was fixed earlier. The channel key
6090 was used be to distributed to other routers as well which is not
6091 allowed by the protocol. Now this is fixed and channel keys
6092 really are cell specific and the channel message delivery between
6093 routers comply with the protocol specification.
6095 * Fixed various commands in server to check also the global list
6096 for the channel entry and not just the local list. The affected
6097 file silcd/command.c.
6099 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Added assert()s to buffer formatting and unformatting routines
6102 to assert (if --enable-debug) when error occurs. Affected
6103 file: lib/silcutil/silcbuffmt.c.
6105 * Changed to auto-reconnect to check whether the remote host is
6106 router and register the re-connect timeout if it is. It used
6107 to check that whether we are normal server, but router must do
6108 auto-reconnect with another router as well. Affected file
6111 * Removed the [<key len>] option from CMODE command as the cipher
6112 name decides the key length, nowadays. See the defined ciphers
6113 from the protocol specification.
6115 * Added [<hmac>] option to the CMODE command to define the HMAC
6116 for the channel. Added SILC_CMODE_HMAC channel mode.
6118 * Added [<hmac>] option for the JOIN command so that user can
6119 select which HMAC is used to compute the MACs of the channel
6122 * Added Hmac field to the Channel Message Payload. The integrity
6123 of plaintext channel messages are now protected by computing
6124 MAC of the message and attaching the MAC to the payload. The
6125 MAC is encrypted. Now, it is clear that this causes some
6126 overhead to the size of the packet but rationale for this is that
6127 now the receiver can verify whether the channel message decrypted
6128 correctly and also when private keys are set for the channel the
6129 receiver can decrypt the packet with several keys and check from
6130 the MAC which key decrypted the message correctly.
6132 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6133 lib/silccrypt/silccipher.[ch].
6135 * Added silc_hash_len to return the digest length into the
6136 lib/silcrypt/silchash.[ch].
6138 * Rewrote parts of Silc Channel Payload interface in the
6139 lib/silccore/silcchannel.[ch]. The encode function now also
6140 encrypts the packet and parse function decrypts it.
6142 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Fixed a minor formatting bug in the SKE's key material processing.
6145 It actually might have processed the keys wrong way resulting
6148 * Redefined the mandatory HMAC algorithms and added new algorithms.
6149 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6150 and hmac-md5 truncated to 96 bits. The mandatory is now
6151 hmac-sha1-96. Rest are optional (including the one that used
6152 to be mandatory). Rationale for this is that the truncated HMAC
6153 length is sufficient from security point of view and can actually
6154 make the attack against the HMAC harder. Also, the truncated
6155 HMAC causes less overhead to the packets. See the RFC2104 for
6158 * Added new [hmac] configuration section. The SKE used to use
6159 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6160 is of course wrong. The official names that must be proposed in
6161 the SKE are the ones defined in the protocol specification
6162 (hmac-sha1-96 for example). The user can configure any hmac
6163 using any hash function configured in the [hash] section. At
6164 least, the mandatory must be configured.
6166 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6168 * Added HMAC list to the SKE proposal list. It has now both
6169 hash algorithm list and HMAC list. This makes the protocol
6170 incompatible with previous versions. The SKE now seems to work
6171 the way it is supposed to work, for the first time actually.
6173 * Defined plain Hash algorithms to the protocol specification.
6176 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Implemented support for key agreement packets into the server.
6179 Added functions silc_server_key_agreement and
6180 silc_server_send_key_agreement. Other than these functions,
6181 server has nothing to do with this packet.
6183 * Added support for private message key packets into the server.
6184 Added functions silc_server_private_message_key and
6185 silc_server_send_private_message_key.
6189 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6190 called in the protocol's final callback instead in the END
6191 protocol state. This makes a little more sense and in the same
6192 time in client we can use the same protocol routines for normal
6193 key exchange and to key agreement packet handling as well.
6195 * Added to both client's and server's KE protocol context the
6196 SilcSKEKeyMaterial pointer to save the key material. We will
6197 bring the key material to the protocol's final callback by doing
6198 this. The final callback must free the key material.
6200 * Added SKE's packet_send callback into client's KE protocol
6201 context so that the caller can choose what packet sending function
6202 is used. This way we can use different packet sending when
6203 doing normal SKE when doing key agreement packet handling (in
6204 the key agreement packet handling we do not want to encrypt
6207 * Implemented the responder side of the key agreement routines
6208 in the client. The client can now bind to specified port and
6209 accept incoming key negotiation. The key material is passed
6210 to the application after the protocol is over.
6212 * Implemented the processing of incoming Key Agreement packet
6213 in the client. Added function silc_client_key_agreement to
6216 * Implemented the intiator side of the key agreement routines
6217 in the client. The client can now initiate key agreement with
6218 another remote client. The key material is passed to the
6219 application after the protocol is over.
6221 * Created client_keyagr.c to include all the key agreement
6224 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6225 SILC_TASK_CALLBACK except that it is not static.
6227 * Created client_notify.c and moved the Notify packet handling
6228 from the client.[ch] into that file.
6230 * Created client_prvmsg.c and moved all private message and
6231 private message key routines from the client.[ch] into that file.
6233 * Create client_channel.c and moved all channel message and
6234 channel private key routines from the client.[ch] into that file.
6236 * Changed silc_client_get_client_by_id_resolve to resolve with
6237 WHOIS command instead of IDENTIFY command, in the file
6238 lib/silclient/idlist.c.
6240 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6242 * Implemented the SKE's responder side to the Client library.
6244 * When FAILURE is received to the protocol do not trust it
6245 blindly. Register a timeout to wait whether the remote closes
6246 the connection as it should do it, only after that process the
6247 actual failure. This was changed to both client and server.
6249 * Added client_internal.h to include some of the structures
6250 there instead of client.h in lib/silcclient/.
6252 * Added function silc_task_unregister_by_callback to unregister
6253 timeouts by the callback function.
6255 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Some "Incomplete WHOIS info" errors has been appearing on the
6258 log files. Took away the entry->userinfo check from WHOIS
6259 reply sending. The entry->userinfo is now " " if client did not
6260 provide one. I thought this was fixed earlier but something
6261 is wrong still. Let's see if the error still appears.
6263 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Fixed a minor bug in the login when the channel key is
6266 re-generated in the server. It used to generate the key in
6267 wrong order and thus caused problems in the channel traffic.
6269 * Fixed a minor bug in channel key distsribution after
6270 KICK command. The key was not sent to the router even though
6273 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6275 * Added silc_ske_process_key_material_data as generic routine
6276 to process any key material as the SILC protocol dictates. The
6277 function is used by the actual SKE library but can be used by
6278 applications as well. This relates to the private message keys
6279 and the channel private keys since they must be processed the
6280 same way the normal SILC session keys. The protocol dictates
6281 this. Affected files: lib/silcske/silcske.[ch].
6283 Added also silc_ske_free_key_material to free the
6284 SilcSKEKeyMaterial structure.
6286 * Defined silc_cipher_set_key function to set the key for
6287 cipher without using the object's method function. The affected
6288 files: lib/silccrypt/silccipher.[ch].
6290 * Implemented silc silc_client_add_private_message_key,
6291 silc_client_add_private_message_key_ske,
6292 silc_client_del_private_message_key,
6293 silc_client_list_private_message_keys and
6294 silc_client_free_private_message_keys functions in the
6297 Added functions silc_client_send_private_message_key to send
6298 the Private Message Key payload and silc_client_private_message_key
6299 to handle incoming Private Message Key payload.
6301 * Added Cipher field to the Private Message Key payload to set
6302 the cipher to be used. If ignored, the default cipher defined
6303 in the SILC protocol (aes-256-cbc) is used.
6305 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Removed lib/silcclient/ops.h file.
6309 Redefined parts of the SILC Client Library API. Created new
6310 file silcapi.h that deprecates the ops.h file and defines the
6311 published Client Library API. Defined also private message key
6312 API and channel private key API into the file.
6314 This is the file that the application must include from the
6315 SILC Client Library. Other files need not be included by
6316 the application anymore.
6318 * Added new key_agreement client operation callback and also
6319 defined the Key Agreement library API for the application.
6321 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6324 is used by clients to request key negotiation between another
6325 client in the SILC network. If the negotiation is started it
6326 is performed using the SKE protocol. The result of the
6327 negotiation, the secret key material, can be used for example
6328 as private message key.
6330 Implemented the Key Agreement payload into the files
6331 lib/silccore/silauth.[ch].
6333 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Redefined ciphers for the SILC protocol. Added some new ciphers
6336 and defined the key lengths for the algorithms. Changed the
6337 code accordingly. The default key length is now 256 bits.
6339 * Fixed SKE key distribution function silc_ske_process_key_material
6340 when the key length is more than 128 bits. The default key
6341 length in SILC is now 256 bits.
6343 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6344 to indicate unsupported algorithm.
6346 * Renamed rijndael.c to aes.c and all functions as well.
6348 * Fixed a long standing channel key setting bug in client library.
6349 Weird that it has never surfaced before.
6351 * Fixed bug in channel deletion. If the entire channel is removed
6352 then it must also delete the references of the channel entry
6353 from the client's channel list as the client's channel entry and
6354 the channel's client entry share same memory.
6356 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6358 * Implemented CONNECT and SHUTDOWN commands in the client.
6360 * Implemented CLOSE command to the client.
6362 * Added the function silc_idlist_find_server_by_name into the
6363 files silcd/idlist.[ch].
6365 Added the function silc_idlist_find_server_by_conn into the
6366 files silcd/idlist.[ch].
6368 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6370 * DIE command was renamed to SHUTDOWN. Updated the both code
6373 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6374 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6376 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6379 * Added function silc_server_create_connection function to create
6380 connection to remote router. My server implementation actually
6381 does not allow router to connect to normal server (it expects
6382 that normal server always initiates the connection to the router)
6383 so the CONNECT command is only good for connecting to another
6386 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6388 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6389 or some other client was kicked from the channel.
6391 Implemented the handling of the notify type to both client
6394 Implemented silc_server_send_notify_kicked to send the KICKED
6395 notify. It is used to send it to the server's primary router.
6397 * Implemented the KICK command into server and client.
6399 * Added `query' argument to the silc_idlist_get_client function
6400 to indicate whether to query the client from server or not if
6403 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6404 to indicate that the client is not channel founder.
6408 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Removed the rng context from SilcPacketContext structure and
6411 changed that the packet routine uses the Global RNG API.
6413 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6415 * Added support for quit message that client can "leave" on the
6416 channel when it quits the SILC. It is ditributed inside the
6417 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6419 Added silc_server_free_client_data that will take the
6420 signoff message as argument.
6422 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6424 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Updated parts of the protocol specification to keep it up
6429 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6431 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6432 payloads in one packet.
6434 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6435 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6436 use now the new List flag.
6438 * Also deprecated the following packet types: REPLACE_ID,
6439 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6441 * Added list support for Notify packet in server.
6443 * Added silc_server_send_notify_channel_change to send the
6444 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6445 the silc_server_send_replace_id.
6447 * Added silc_server_send_notify_nick_change to send the
6448 NICK_CHANGE notify type. Deprecates the function
6449 silc_server_send_replace_id.
6451 * Added silc_server_send_notify_join to send the JOIN notify type.
6452 Deprecates the function silc_server_send_new_channel_user.
6454 * Added silc_server_send_notify_leave to send LEAVE notify type.
6455 Deprecates the function silc_server_send_remove_channel_user.
6457 * Added silc_server_send_notify_cmode and
6458 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6459 types. Deprecates the silc_server_send_set_mode function.
6461 * Added SERVER_SIGNOFF notify type to indicate that server has
6462 quit. This means that all clients on the channel from that
6463 server will drop. This can be also used when netsplit happens.
6465 Deprecated REMOVE_ID packet type since it is not needed anymore
6468 Added silc_server_send_notify_server_signoff to send the
6469 SERVER_SIGNOFF notify type. Deprecates the function
6470 silc_server_send_remove_id.
6472 Added also silc_server_send_notify_signoff to send the
6473 SIGNOFF notify type.
6475 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6476 SILC protocol from this day on. Changed the protocol
6477 specification as well.
6479 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6480 notify type. It is used between routers to notify about
6481 topic changes on a channel.
6483 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6486 * Partly updated the protocol specification to comply with the
6487 changes now made. It is still though a bit outdated.
6489 * The JOIN notify type now takes one extra argument <Channel ID>.
6490 The packet used to be destined to the channel but now the
6491 JOIN type may be sent as list thus it is impossible to
6492 destine it to any specific channel. By adding this argument
6493 it is again possible.
6495 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Added CREDITS file. The CHANGES and CREDITS file will appear
6498 in the distribution as well.
6500 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6502 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6503 types in the server's silcd/packet_receive.c.
6505 * Implemented CMODE and CUMODE to work in router environment.
6507 * Fixed minor encoding and decoding buglet from the
6508 lib/silccore/silcmode.c.
6510 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6513 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6515 * Changed all SilcConfigServer* and silc_config_server* to
6516 SilcServerConfig* and silc_server_config*, respectively.
6519 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6521 * Associated the ID (client or server ID) to the Authentication
6522 Payload to avoid any possibility of forging. Updated the
6523 protocol specification and the code accordingly.
6525 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6527 * The RSA key length is now save to the RsaKey context in the
6528 key generation process in lib/silccrypt/rsa.c. The key length
6529 is now used to figure out the maximum size of the block allowed
6530 to be encrypted/signed.
6532 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6533 is equivalent to the silc_mp_mp2bin but does not allocate any
6536 * Changed silc_mp_mp2bin API to take length argument. If it is
6537 non-zero then the buffer is allocated that large. If zero, then
6538 the size is approximated using silc_mp_sizeinbase, which however
6541 * Created Global RNG API which is global RNG that application can
6542 initialize. After initializing, any routine anywhere in the
6543 code (including library) can use RNG without allocating a new
6544 RNG object. This was done to allow this sort of use of the
6545 RNG in code that has no chance to allocate RNG object. All
6546 applications currently allocate this and many routines in the
6547 library use this. Affected file lib/silccrypt/silcrng.[ch].
6549 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6550 it to use the Global RNG API.
6552 * Defined Authentication Payload into protocol specification that
6553 is used during SILC session to authenticate entities. It is
6554 used for example by client to authenticate itself to the server
6555 to obtain server operator privileges.
6557 Implemented this payload into the lib/silccore/silcauth.[ch].
6558 Implemented also routines for public key based authentication
6559 as the new protocol specification dictates.
6561 Moved definitions of different authentication methods from
6562 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6564 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6565 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6566 silc_pkcs_verify_with_hash functions into the file
6567 lib/silccrypt/silcpkcs.[ch].
6569 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6571 * The client entry's userinfo pointer must be always valid.
6572 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6573 will fail since it requires the userinfo. Now, the userinfo
6574 is allocated as "" if actual userinfo does not exist. Actually,
6575 it must exist and it is totally Ok to drop client connections
6576 that does not announce the userinfo. However, we will make
6577 this workaround for now.
6579 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6580 to return the remote port by socket.
6582 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6585 SILC_SERVER_PENDING_EXEC and added an new macro
6586 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6587 data or when error occurs while processing the pending command.
6589 Added new argument `destructor' into silc_server_command_pending
6590 and to the SilcServerCommandPending object. This destructor is
6591 now called after calling the pending callback or if error occurs
6592 immediately. If error occurs the actual pending callback won't
6593 be called at all - only the destructor. The destructor may be
6594 NULL if destructor is not needed.
6596 All this applies for client library code as well. Similar
6597 changes were made there as well for the pending commands.
6599 In the client, the application must now allocate the
6600 SilcClientCommandContext with the silc_client_command_alloc
6603 * Added reference counter to the SilcServerCommandContext. Added
6604 function silc_server_command_alloc and silc_server_command_dup
6607 Same type of functions added to the client library for the same
6610 * Removed the cmd_ident from IDListData away since it is now
6611 global for all connections. It is the command identifier used
6612 in command sending and with pending commands. The affected file
6615 * Added reference counter to the SilcSocketConnection objecet to
6616 indicate the usage count of the object. The object won't be
6617 freed untill the reference counter hits zero. Currently only
6618 server uses this, and client ignores it. The client must be
6619 set to use this too later. The affected files are
6620 lib/silccore/silcsockconn.[ch]. Added also the function
6621 silc_socket_dup to increase the reference counter.
6623 This was mainly added because it is possible that the socket
6624 is removed underneath of pending command or other async
6625 operation. Now it won't be free'd and proper DISCONNECTING
6626 flags, etc. can be set to avoid sending data to connection that
6627 is not valid anymore.
6629 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6630 the connection. After that it sets SILC_SET_DISCONNECTED.
6631 It is, however, possible that the socket data is not still freed.
6632 The silc_server_packet_process now checks that data is not
6633 read or written to connection that is DISCONNECTED. The socket
6634 get's freed when the reference counter hits zero.
6636 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6638 * Changed the client operation API: channel_message operation's
6639 `sender' is now the client entry of the sender, not the nickname
6640 and the `channel' is the channel entry, not the channel name.
6642 In the private_message operation the `sender' is now also the
6643 client entry of the sender not the nickname.
6645 Affected file is lib/silcclient/ops.h and all applications
6646 using the client operations.
6648 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6650 * Moved the calling of ops->connect() from connect_to_server_final
6651 into receive_new_id functin since that is the point when the
6652 client is actually allowed to send traffic to network. The
6653 affected file is lib/silcclient/client.c.
6655 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6657 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6658 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6659 (if needs broadcasting) instead of broadcasting the packets one
6660 by one which would make a burst in the network traffic.
6662 * Added `broadcast' argument to the functions in silcd/server.[ch]
6663 silc_server_create_new_channel[_with_id] to indicate whether
6664 to send New Channel packet to primary router.
6666 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Added new function into the silcd/server.[ch] files:
6669 silc_server_create_new_channel_with_id to create new channel with
6670 already existing Channel ID.
6672 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6673 lib/silccore/silcpacket.h. This packet is used t send list of
6674 Set Mode payloads inside one packet. Server uses this to set
6675 the modes for the channels and clients on those channels, that it
6676 announced to the router when it connected to it. The protocol
6677 specification has been updated accordingly.
6679 * The silc_server_new_channel did not handle the packet coming
6680 from normal server as it normally does not send that. However,
6681 when it announces its channels it does send it. Implemented
6682 the support for that.
6684 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6685 into the file lib/silccore/id.h.
6687 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6689 * Fixed memory leaks in the functions silc_idlist_del_client,
6690 silc_idlist_del_channel and silc_idlist_del_server in the file
6691 silcd/idlist.c. All of those leaked like a sieve.
6693 * Fixed some small memory leaks in the client's function
6694 silc_client_notify_by_server.
6696 * Added functions into silcd/server.c: silc_server_announce_clients,
6697 silc_server_announce_channels and silc_server_announce_server.
6698 These functions are used by normal and router server to announce
6699 to its primary router about clients, channels and servers (when
6700 router) that we own. This is done after we've connected to the
6703 These functions effectively implements the following packet types:
6704 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6705 and SILC_PACKET_NEW_ID_LIST.
6707 * Added new functions into the silcd/packet_receive.[ch]:
6708 silc_server_new_id_list, silc_server_new_channel_list and
6709 silc_server_new_channel_user_list to handle the incoming
6710 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6712 * Added support of changing Channel ID in the function
6713 silc_server_replace_id. If the server that announces a channel
6714 to the router already exists in the router (with same name but
6715 with different Channel ID), router is responsible to send
6716 Replace ID packet to the server and force the server to change
6717 the Channel ID to the one router has.
6719 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6720 client that the Channel ID has been changed by the router. The
6721 normal server sends this to the client. Client must start using
6722 the new Channel ID as the channel's ID.
6724 Implemented handling of this new type into lib/silcclient/client.c
6725 into the function silc_client_notify_by_server.
6727 * Added new function silc_idlist_replace_channel_id into the files
6728 silcd/idlist.[ch] to replace the Channel ID.
6730 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6732 * Call silc_server_command_identify_check always when processing
6733 the IDENTIFY command in silcd/command.c
6735 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6737 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6738 send keepalive packets. The packet can be sent by clients,
6739 servers and routers.
6741 Added function silc_socket_set_heartbeat into the file
6742 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6743 If not set, the heartbeat is not performed. The actual
6744 heartbeat is implemented in the low level socket connection
6745 library. However, application is responsible of actually
6748 Added silc_server_send_heartbeat to send the actual heartbeat
6749 packet into silcd/packet_send.[ch]. Server now performs
6750 keepalive with all connections.
6752 * Added silc_task_get_first function into lib/silcutil/silctask.c
6753 to return the timeout task with shortest timeout. There was a bug
6754 in task unregistration that caused problems. TODO has been
6755 updated to include that task system must be rewritten.
6757 * The client library will now resolve the client information when
6758 receiving JOIN notify from server for client that we know but
6759 have incomplete information.
6761 * Rewrote parts of silc_server_remove_from_channels and
6762 silc_server_remove_from_one_channel as they did not remove the
6763 channel in some circumstances even though they should've.
6765 * Encryption problem encountered in server:
6767 The LEAVE command used to send the Channel Key packet to the
6768 router immediately after generating it. However, the code
6769 had earlier sent Remove Channel user packet but not immediately,
6770 ie. it was put to queue. The order of packets in the router
6771 was that Channel Key packet was first and Remove Channel User
6772 packet was second, even though they were encrypted in the
6773 reverse order. For this reason, MAC check failed. Now, this
6774 is fixed by not sending the Channel Key packet immediately but
6775 putting it to queue. However, this is more fundamental problem:
6776 packets that are in queue should actually not be encrypted
6777 because packets that are sent immediately gets encrypted
6778 actually with wrong IV (and thus MAC check fails). So, packets
6779 that are in queue should be encrypted when they are sent to
6780 the wire and not when they put to the queue.
6782 However, the problem is that the current system has not been
6783 designed to work that way. Instead, the packet is encrypted
6784 as soon as possible and left to the queue. The queue is then
6785 just purged into wire. There won't be any fixes for this
6786 any time soon. So, the current semantic for packet sending
6789 o If you send packet to remote host and do not force the send
6790 (the packet will be in queue) then all subsequent packets to the
6791 same remote host must also be put to the queue. Only after the
6792 queue has been purged is it safe again to force the packet
6795 o If you send all packets immediately then it safe to send
6796 any of subsequent packets through the queue, however, after
6797 the first packet is put to queue then any subsequent packets
6798 must also be put to the queue.
6800 Follow these rules and everything works fine.
6802 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6804 * Added new function silc_server_remove_clients_by_server to
6805 remove all client entries from ID list when the server connection
6806 is lost. In this case it is also important to invalidate all
6807 client entires as they hold the invalid server entry. This
6808 fixes fatal bug when server has lost connection and will reconnect
6811 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6813 * Made some sanity checks to silc_server_daemonise like to check
6814 whether the requested user and group actually exists.
6816 * Added sanity check to SKE's silc_ske_responder_finish to check
6817 that the public and private key actually is valid.
6819 * Invalidate the client's nickname when receiving Replace ID
6820 packet and the Client ID is being replaced. This means that the
6821 server will query the nickname if someone needs it (client)
6824 * Sort the ID Cache in client library when the ID Cache data
6825 has changed (needs sorting).
6827 * Do not allow for SILC client to create several connections to
6828 several servers. The client does not support windows right now
6829 and generating multiple connections causes weird behaviour.
6831 Irssi-silc client does support windows and can handle several
6832 connections without problems, see: www.irssi.org and SILC plugin.
6834 * Fixed some places where client was added to the IDList. The
6835 rule of thumb is following (in order to get everything right):
6836 If the client is directly connected local client then the
6837 `connection' argument must be set and `router' argument must be
6838 NULL to silc_idlist_add_client function. If the client is not
6839 directly connected client then the `router' argument must
6840 bet set and the `connection' argument must be NULL to the
6841 silc_idlist_add_client function.
6843 * The funtion silc_server_packet_send_local_channel actually did
6844 not check whether the client was locally connected or not. It
6845 does that now. Fixed a bug related to LEAVE command.
6847 * Fixed Remove Channel User payload parsing bug in server's
6848 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6850 * The server's silc_server_save_channel_key now checks also the
6851 global ID list for the channel as it might not be in the local
6852 list. Fixed a bug related to LEAVE command.
6854 * Is this the end of the [<unknown>] buglet that has been lurking
6855 around for a long time? A little for loop fix in server's
6856 silc_server_command_whois_parse that is used by both IDENTIFY
6857 and WHOIS command. At least, this was a clear bug and a cause
6858 of one type of [<unknown>] buglet.
6860 * WHOIS and IDENTIFY commands call the function
6861 silc_server_command_[whois/identify]_check function even if
6862 we are not router server.
6864 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6866 * Added --with-gmp configuration option. If set the GMP
6867 is always compiled in the SILC source tree. If not set then
6868 it is checked whether the system has the GMP3 installed. If
6869 it has then the GMP won't be compiled (the system's headers
6870 and library is used), if it doesn't have it then the GMP is
6871 compiled in the SILC source tree.
6873 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Changed RSA private exponent generation to what PKCS #1
6876 suggests. We try to find the smallest possible d by doing
6877 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6878 not security fix but optimization.
6880 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6882 * Added new config entry [Identity] to fork the server and run
6883 it as specific user and group. A patch from Bostik.
6885 * Imported Dotconf configuration library into lib/dotconf.
6886 This will be used to create the SILC configuration files later.
6887 It will appear in the distsribution after this commit.
6889 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6891 * A big code auditing weekend happening. Auditing code for
6892 obvious mistakes, bugs and errors. Also, removing any code
6895 Removed files for being obsolete:
6897 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6898 inline in the file lib/silcutil/silcbuffer.h)
6900 o lib/silcutil/silcbufutil.c (the header has inline versions)
6902 Changed code to fix possible error conditions:
6904 o The buffer formatting routines now check that the destination
6905 buffer really has enough space to add the data. This applies for
6906 both buffer formatting and unformatting
6907 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6908 unformatting was changed to accomodate following rules:
6909 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6910 sent to the function while XXX_*STRING will not allocate or copy
6911 the data into the buffer. Instead it sets the pointer from the
6912 buffer into the pointer sent as argument (XXX_*STRING used to
6913 require that the pointer must be allocated already). This change
6914 makes this whole thing a bit more consistent and more optimized
6915 (note that the data returned in the unformatting with XXX_*STRING
6916 must not be freed now). The routines return now -1 on error.
6918 o Tried to find all code that use buffer_format and buffer_unformat
6919 and added return value checking to prevent formatting and
6920 especially unformatting errors and possible subsequent fatal
6923 o Changed ske->x and ske->KEY to mallocated pointers in
6924 lib/silcske/silcske.h. Fixed possible data and memory leak.
6926 o Added return value checking to all *_parse* functions. Fixed
6927 many memory leaks as well.
6929 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6930 so that buffer overflows would not happen. All code now also
6931 checks the return value as it can fail.
6933 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6935 * Added reconnection support to server if the normal server looses
6936 its connection to the router (for example if router is rebooted).
6937 The server performs normal reconnection strategy implemented
6938 to the server. Affected file silcd/server.c.
6940 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Added new packet type SILC_PACKET_SET_MODE that is used to
6943 distribute the information about changed modes (for clients,
6944 channels and clients channel modes) to all routers in the
6945 network. Updated the protocol specification accordingly.
6947 Added functions into silcd/packet_send.c and
6948 silcd/packet_receive.c: silc_server_send_set_mode,
6949 silc_server_set_mode.
6951 Added new files silcmode.[ch] into lib/silccore that implements
6952 the encoding and decoding of Set Mode Payload. Added new type
6953 SilcSetModePayload. Moved the definitions of different modes
6954 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6956 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6958 * Oops, a little mistake in server's connection authentication
6959 protocol. The protocol is not ended with FAILURE but with
6960 SUCCESS if the authentication is Ok. :) Affected file is
6963 * Implemented NICK_CHANGE notify handling in server in the file
6964 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6965 the local clients on the channel. After the changing nickname
6966 in router environment snhould work and the [<unknown>] nickname
6967 should appear no more.
6969 The silc_server_replace_id function that receives the Replace ID
6970 payload now sends the NICK_CHANGE notify type also in the file
6971 silcd/packet_receive.c
6973 * Changed WHOIS and IDENTIFY command to support the maximum amount
6974 of arguments defined in protocol specs (3328 arguments). This
6975 fixed a bug that caused problems when there were more than three
6978 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6980 * Added extra parameter, command identifier, to the
6981 silc_client_send_command so that explicit command identifier
6984 Changed that ID list routines uses specific command identifier
6985 when sending WHOIS/IDENTIFY requests to the server so that they
6986 can be identified when the reply comes back.
6988 Affected files lib/silcclient/command.[ch],
6989 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6991 * Added `sender' argument to silc_server_packet_send_to_channel
6992 to indicaet the sender who originally sent the packet to us
6993 that we are now re-sending. Ignored if NULL. Affected file
6994 silcd/packet_send.[ch].
6996 * Added some server statistics support in silcd/server_internal.h
6997 SilcServerStatistics structure and around the server code. Also
6998 send some nice statistics information when client is connecting
7001 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Fixed channel ID decoding in server's JOIN command reply in
7004 silcd/command_reply.c
7006 * Fixed braodcasting of replace ID payload to not to send it if
7007 we are standalone server in silcd/packet_receive.c.
7009 * Fixed all channel message sending routines to not to send
7010 packets to clients that has router set, since they are routed
7011 separately in the same function earlier. Affects file
7012 silcd/packet_send.c and all channel packet sending functions.
7014 * In USERS reply, res_argv[i] are not allocated, the table
7015 is allocated. Thus changed that free the table, not its
7018 * In server's whois_check and identify_check if the client is
7019 locally connected do not send any WHOIS commands - they are not
7022 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7024 * Fixed some minor bugs in client when sending WHOIS command. The
7025 arguments was in wrong order.
7027 * Removed statis function add_to_channel from server in
7028 silcd/command.c that was previously used with the joining but
7031 * Tested USERS command in router environment successfully with two
7032 routers, two servers and two clients.
7034 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7036 * Reorganized the USERS command and command reply in client library
7037 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7038 When the command is given by user we register a pending command
7039 callback that will reprocess the command after the reply has been
7040 received from the server. When reprocessing the packet we then
7041 display the information. Thus, the USERS information is displayed
7042 now in the command callback instead of in the command reply
7043 callback. The processing of the command is same as previously
7044 when server has sent the command reply in the JOINing process.
7046 * Added to USERS command in silcd/command_reply.c to join the client,
7047 we didn't use to know about, to the channel after we've created
7048 a client entry for it. Also, for clienet we did know already still
7049 check whether it is on the channel or not and add it if not.
7051 * Removed silc_server_command_join_notify as the function and its
7054 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7056 * Changed the client's pending command handling to the same as the
7057 server's pending command handling. It is also now possible to
7058 execute command reply functions from other command reply
7059 function as the function callbacks for commands and command
7060 replies are one and same. The pending commands are not static
7061 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7062 in client connection context. Thus, pending commands are server
7063 connection specific as it is convenient.
7065 Changed the function silc_client_command_pending and
7066 silc_client_command_pending_del and added new function
7067 silc_client_command_pending_check. Removed the
7068 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7071 * Added cmd_ident, current command identifier, to the client
7072 connection context in lib/silcclient/client.h to keep track on
7073 command identifiers used in command sending. Client's command reply
7074 function handling now supports the mandatory command identifiers.
7076 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7077 funtions in client to fully support pending command callbacks.
7079 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7080 as one of the arguments to the application in the command reply
7083 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7084 before first releasing SILC but came back. Now it is removed again
7085 and should come back nomore. The FORWARDED flag was used only
7086 by the JOINing procedure by forwarding the command packet to router.
7087 Now, the JOINing procedure has been changed to more generic (due
7088 to various router environment issues) and FORWARDED is not needed
7089 anymore for anything. The protocol specification is yet to be
7092 Now, removed silc_server_packet_forward from server and the flag
7093 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7095 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7097 * Renamed NAMES command to USERS command. The NAMES was named that
7098 due to historical reasons. Now it is renamed. Also, rewrote
7099 parts of the USERS command. The nickname list is not sent anymore
7100 by the server. Only Client ID and mode lists are sent in the USERS
7101 command. Changed this also to the protocol specification.
7103 The client now resolves the names and stuff after it receives
7104 the USERS list from the server when joining to the channel.
7106 * WHOIS and IDENTIFY commands has been changed to support multiple
7107 Client ID's per command. One can now search for multiple users
7108 in the network by sending only one WHOIS or IDENTIFY command.
7109 Changed the code and the protocol specifications.
7111 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7112 uses silc_server_command_whois_parse to parse the request. */
7114 * If normal server, do not parse the WHOIS and IDENTIFY requests
7115 before sending it to the router. Saves some time.
7117 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7119 * Fixed JOIN command on client library. Wrong number of arguments
7120 used to crash the client.
7122 * Added silc_server_channel_has_global function to check whether
7123 channel has global users or not.
7125 * Added silc_server_channel_has_local function to check whether channel
7126 has locally connected clients on the channel.
7128 * The silc_server_remove_from_one_channel now checks whether the
7129 channel has global users or not after given client was removed from
7130 the channel. It also checks whether the channel has local clients
7131 on the channel anymore. If it does not have then the channel entry
7132 is removed as it is not needed anymore.
7134 * The silc_server_notify now checks on JOIN notify whether the joining
7135 client is one of locally connected or global. If it is global then
7136 the channel has now global users on the channel and that is marked
7137 to the channel entry. Also, it now saves the global client to
7138 global list who is joining and JOINs it to the channel. This is
7139 for normal server, that is.
7141 Changed silc_server_send_notify_on_channel,
7142 silc_server_packet_relay_to_channel and
7143 silc_server_packet_send_to_channel check if we are normal server
7144 and client has router set (ie. global client) do not send the
7145 message to that client, as it is already routed to our router.
7147 * Implemented LEAVE notify type handling in silc_server_notify
7150 * Tested LEAVE command in router environment successfully. Tested
7151 with two routers, two servers and two clients.
7155 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7157 * Implemented SIGNOFF notify type handling in silc_server_notify
7160 * silc_server_remove_id now removes the client entry from all channels
7161 it has joined and thusly sends SIGNOFF notify type.
7163 * Rewrote the NAMES list generation in server by removing two excess
7164 loops. The lists are created now inside one loop.
7166 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7168 * silc_server_remove_channel_user checks now also global list
7169 for channel and client.
7171 * silc_server_new_channel_user checks now both local and global
7172 list for channel and client. Fixed a bug in client id decoding.
7173 Used to decode wrong buffer.
7175 * silc_server_channel_message checks now both local and global
7176 list for channel entry.
7178 * Tested channel joining (hence JOIN) in router environment
7179 successfully. Tested with two routers, two servers and two
7182 * Tested channel message sending in router environment successfully.
7184 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7186 * Added silc_server_save_channel_key into server.[ch] to save the
7187 received channel key in Channel Key payload processing. It is
7188 also used in JOIN command reply handling.
7190 Equivalent function silc_client_save_channel_key added into
7191 client.[ch] into client library.
7193 * Changed JOIN command reply to send information whether the channel
7194 was created or not (is existing already) and the channel key
7195 payload. Changed protocol specs accordingly.
7197 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7198 the request was sent by ID and not by nickname. Crashed on
7201 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7203 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7204 now correctly save the received data.
7206 * silc_server_free_sock_user_data now notifies routers in the
7207 network about entities leaving the network.
7209 At the same time implemented functions silc_server_remove_id
7210 and silc_server_send_remove_id to receive and send REMOVE_ID
7211 packets. The packet is used to notify routers in the network
7212 about leaving entities. The ID removed will become invalid in
7215 * Added function silc_idlist_del_server into server. Removes and
7216 free's server entry from ID list.
7218 * silc_server_private_message function now checks, if we are router,
7219 that the destination ID really is valid ID, naturally.
7221 * In router when NEW_ID packet is received (for new client) the
7222 hash of the Client ID is saved in the ID Cache but the
7223 client->nickname is set to NULL, instead of putting the hash
7226 IDENTIFY command now also checks that client->nickname must be
7227 valid. If it is not if will request the data from the server who
7228 owns the client. Added new function
7229 silc_server_command_identify_check.
7231 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7232 to set the command to already allocated Command Payload.
7234 * Tested private message sending in router environment with two
7235 routers, two servers and two clients. Fixed minor bugs and now
7238 * Fixed segfault from client's NAMES command. Used to crash if
7241 * Forwarded packets must not be routed even if it is not destined
7242 to the receiver. Changed server code comply with this.
7244 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7246 * Added `require_reverse_mapping' boolean value to ServerParams
7247 structure. If TRUE (not default) the server will require that
7248 the connecting host has fully qualified domain name.
7250 If the reverse mapping is not required and hostname could not be
7251 found the IP address is used as hostname.
7253 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Implemented version string checking to both client and server.
7256 The check is incomplete currently due to the abnormal version
7257 strings used in development version of SILC.
7259 * Changed all command functions in server to use the new
7262 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7264 * Changed char *data to unsigned char *data in ID Cache system to
7265 support binary data as ID Cache data. Changed code to support
7266 binary data in lib/silccore/idcache.c.
7268 * Renamed silc_server_packet_relay_command_reply to
7269 silc_server_command_reply as it is normal packet receiving
7270 function. Rewrote the function to accept command replys for
7271 servers and not only for clients.
7273 * Mark remote router always as registered server if we are connecting
7274 to it. Otherwise, commands sent by the router to us are ignored.
7276 * All ID List find routines now returns the ID Cache Entry pointer
7277 as well if requested.
7279 * WHOIS command works now in router environment, tested with two
7280 routers, two servers and two clients.
7282 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7283 in router environment (as it is almost equivalent to WHOIS) but
7284 hasn't been tested thoroughly. Added new functions:
7286 silc_server_command_identify_parse
7287 silc_server_command_identify_send_reply
7288 silc_server_command_identify_from_client
7289 silc_server_command_identify_from_server
7291 * Disabled route cache adding because adding two different ID's with
7292 same IP replaces the old cache entry thus giving wrong route.
7293 The entry->router->connection is always the fastest route anyway
7294 so route cache may not be needed. Of course, new routes maybe
7295 established after receiving the ID when the entry->router->connection
7296 might not be anymore the most optimal.
7298 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7300 * Add route cache for received ID for fast routing.
7302 * Added silc_server_packet_route to route received packet on router
7303 that is not destined to us.
7305 * Renamed silc_server_get_route to silc_server_route_get.
7307 * Added id_string and id_string_len fields into SilcServer to
7308 include encoded ServerID for fast comparing without excess
7309 encoding of the ID's.
7311 * Cleaned up WHOIS command on server side. Added following static
7314 silc_server_command_whois_parse
7315 silc_server_command_whois_check
7316 silc_server_command_whois_send_reply
7317 silc_server_command_whois_from_client
7318 silc_server_command_whois_from_server
7320 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7321 arguments in command replies. All command functions should be
7322 updated to use this macro.
7324 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Minor typo fixes on command reply handling on server.
7328 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7330 * Added silc_server_command_add_to_channel internal routine to add
7331 the client to the channel after router has created the channel and
7332 sent command reply to the server.
7334 * Added generic silc_server_send_command to send any command from
7337 * Use static buffer with ID rendering instead of duplicating data.
7339 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7341 * Fixed a channel user mode bug when joining to a channel server gave
7342 everybody channel founder rights, oops.
7344 * We mark ourselves as the router of the incoming server connection
7345 if we are router ourselves. This way we can check in some packet
7346 sending functions whether it is locally connected server. For
7347 incoming router connections we put NULL.
7349 * For router sending packets locally means now always sending the
7350 packet cell wide; to local clients and local servers. For normal
7351 server sending packet locally means sending it to only local
7354 * Fixed the JOIN command to really work in router environment. If the
7355 channel is created it is always created by the router. Router is
7356 also responsible of making the initial joining to the channel,
7357 sending JOIN notify to the sending server and distributing
7358 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7359 does not exist server doesn't do anything else but forward the
7360 command to the router which performs everything.
7362 * Added silc_server_send_channel_key function to send the Channel Key
7365 * Added silc_server_create_channel_key to create new channel key. The
7366 channel key is now re-generated everytime someone joins or leaves
7367 a channel, as protocol dictates. Note: channel->key_len is the
7370 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7372 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7373 packet_receive.[ch] to separate packet sending and receiving
7374 routines. The server.[ch] now includes everything else including
7375 actual packet processing (writing and reading data) and other
7378 Renamed silc_server_private_message_send_internal to
7379 silc_server_send_private_message. The routine is still though
7380 used only to relay private messages as server does not send
7381 private messages itself.
7383 Renamed silc_server_new_channel to silc_server_create_new_channel
7384 and added new function sicl_server_new_channel that handles the
7385 incoming New Channel packet. Added also new sending function
7386 silc_server_send_new_channel to send New Channel Payload.
7388 * Added new function silc_server_notify to process incoming notify
7389 packet to the server/router. Server may then relay the notify
7390 to clients if needed.
7392 * Added new function silc_server_new_channel_user to process incoming
7393 New Channel User packet. Router will redistribute the packet and
7394 send JOIN notify to its local clients and locally connected servers
7395 if needed. Normal server will send JOIN notify to its local client
7396 on same channel when received this packet. Added also corresponding
7397 sending function silc_server_send_new_channel_user to sent the
7400 * Added boolean route argument to send_notif_to_channel and
7401 packet_send_to_channel functions to attempt to route the packet
7402 if it is TRUE and send only locally if it is FALSE.
7404 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7406 * silc_server_replace_id now broadcasts the received replace ID
7407 packet if it is not broadcast packet already. The router must
7408 broadcast to inform other routers about changed ID.
7410 * Added backpointer to server's router into SilcServer context in
7411 silcd/server_internal.h.
7413 * Fixed silc_server_packet_broadcast to send correct broadcast
7416 * The channel key is now distributed to the local client as soon
7417 as it is received from the router (in router environment) so that
7418 no other packet may be sent for the channel until client has
7421 * silc_server_remove_channel_user now broadcasts the received
7422 Remove Channel User packet if it is not broadcast packet already.
7423 The router must broadcast to inform other routers about removed
7426 * Added users field into SilcPacketContext that is a reference count
7427 of the context. One can increase the reference count by calling
7428 silc_packet_context_dup which is now changed to just increase the
7429 reference count instead of duplicating the data. The reference
7430 count is decresed by calling silc_packet_context_free that will
7431 free the data after the reference count hits zero.
7433 For now on the packet context and everything allocated into it
7434 (including the raw packet from network) must be freed by calling
7435 the new silc_packet_context_free function. Added also new function
7436 silc_packet_context_alloc that must be used now to allocate the
7437 context. This also means that if a routine is asynchronous from
7438 silc_[client/server]_packet_parse_type the packet context must
7439 be duplicated by calling silc_packet_context_dup. Otherwise it
7440 gets free'd after silc_[client/server]_packet_parse_type returns.
7441 Also, one must remember that if packet is duplicated then its
7442 reference count must be decresed by calling the free function as
7443 many times as it was duplicated.
7445 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7446 from both client and server.
7448 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7450 * Made joining to a channel working in router environment.
7452 * Cleaned up JOIN command on server side and create function
7453 silc_server_command_join_channel internal routine to make the
7456 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7458 * Changed silc_command_pending list to SilcDList. Also, added
7459 `ident' field to SilcServerCommandPending structure to identify
7460 the reply and to call correct callback.
7462 Added silc_server_command_pending_check function to replace the
7463 corresnponding macro. The silc_command_pending list is not
7466 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7467 to set identifier to previously allocated Command Payload. It
7468 is used to set identifier for command when resending Command
7471 * Added silc_command_payload_encode_payload to encode Command
7472 Payload buffer from SilcCommandPayload structure.
7474 * Added silc_argument_payload_encode_payload to encode Argument
7475 payload buffer from SilcArgumentPayload structure.
7477 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7479 * Changed WHOIS command to support router connection on server side.
7480 The whois request is always sent to router unless the server is
7481 standalone server. After server has received the reply from the
7482 router will it send the reply to the client.
7484 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7485 broadcast received broadcast packet. The function is used only
7486 by router. The broadcast packet is always sent to the router's
7489 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7490 render given ID to printable string, for log files for example.
7492 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7494 * Made basic router to router connections working. At least they
7495 can now connect to each other but nothing really works the way
7496 they are supposed - yet.
7498 * Added new initiator token to RouterConnection configuration
7499 file in silcd/serverconfig.[ch]. It is used to tell whether we
7500 are the initiator to the remote router or whether we'll expect
7501 the other end to connect.
7503 * Moved registering of listener task to silc_server_init, hence
7504 the server starts listenning as soon as it is run, even if it
7505 does not have connections to other routers. Let's see how well
7508 * Changed default connection retry timeouts for more suitable in
7511 * Removed cipher and such arguments from silc_idlist_add_client
7512 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7513 Added new function silc_idlist_add_data to add the keys and stuff
7516 * Added SilcIDListData structure and added it to SilcClientEntry
7517 and SilcServerEntry as their first field in the structure. This
7518 way we can explicitly cast the ID entries to the SilcIDListData
7519 structure and get common data for the entries. In past, we had
7520 to first check what type of connection it is and then cast it to
7521 correct ID entry type. Now, we can directly cast the opaque
7522 pointer to the SilcIDListData (no matter what ID entry it actually
7523 is) and get the data needed.
7525 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7527 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7528 in some circumstances even if threre were timeout tasks, though not
7529 IO tasks, but tasks anyway. Now fixed.
7531 * Defined SilcServerConnection structure to hold connection specific
7532 stuff about directly connected servers and routers. The definition
7533 is currently in silcd/server_internal.h. I thought about having
7534 a bit more important role fro this struct but for now it is used
7535 only when connecting to other server (or router actually).
7537 * Added connecting retry support in server when connecting to
7538 router(s). The retry feature implement exponential backoff
7539 algorithm. Also, added SilcServerParams structure to hold default
7540 parameters for server. For now, it include these retry settings
7541 and are hard coded. After server is moded to be as Silc Server
7542 Library this structure will be more important.
7544 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7546 * Changed client librarys channel->clients table to SilcList and
7547 changed code accordingly.
7549 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7551 * Changed client's channel table to SilcList and changed code
7552 accordingly. Also changed SilcChannelClientEntry to include back-
7553 pointer to the channel so that client entry can use that structure
7554 as list as well and we have fast cross-reference to the channel.
7555 This change dramatically decreased the complexity of channel
7556 handling with client entry and vice versa (removed one extra
7557 loop when searching for channel entry from many functions).
7559 * Changed server->sim from table to SilcDList and changed code
7562 * NAMES command can now be used from user interface. It will show
7563 the user list on the channel, neatly.
7565 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7566 Code now saves realname of the user if it becomes available.
7568 * Renamed configure.in to configure.in.pre and made ./prepare
7569 script to automatically add correct version string to
7570 configure.in which it creates from configure.in.pre.
7572 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7574 * NAMES command reply now shows users mode with the nickname when
7577 * Moved silc_client_ch[u]mode[_char] functions from
7578 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7579 place sucks, they are utility functions and should be in some
7582 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7584 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7587 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7591 * Added TRQ (efficient deque and list library) into lib/trq. This is
7592 a very good list library that is currently used in the SILC. Defined
7593 SilcList API over the library because I didn't like the API very
7594 much. See lib/trq/silclist.h for the API and examples of how to
7595 use the API. Fixed various places in the code to use the new
7596 SilcList API. The SilcList is meant for lists that has a structure
7597 already defined as a list. It is not suitable to add just some
7598 context to the list (in TRQ, the context is the list actually).
7600 So, I defined SilcDList that can be used for the purpose where
7601 predefined list structure does not exit. This can be used as
7602 such list. Now some context just can be added to the SilcDList.
7603 Currently this list is not used in the SILC just yet, though there
7604 are a lot places where this can replace dynamically allocated
7605 tables and I will fix these places, later, to use SilcDList.
7606 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7607 and use TRQ internally).
7609 Also fixed some annoying warning messages that the original TRQ
7610 code generated. Also minor changes to TRQ's Makefile.in.
7612 * Added support for querying by Client ID to both WHOIS and
7613 IDENTIFY commands into server, as required by the protocol.
7615 * Removed method function pointers from SilcBuffer structure. They
7616 weren't used to anything and just increased the context size for
7617 no good reason. This change also made silc_buffer_alloc and
7618 silc_buffer_free functions inline functions.
7620 * Disabled command flooding detection support until it's fixed so
7621 that it accepts commands in but does not execute them more than once
7624 * Added silc_net_localhost(), to return local hostname, into
7625 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7626 that must be initialized before calling silc_client_init.
7628 * Added new function: silc_server_send_notify_on_channels to send
7629 notify messages to all channels client has joined. It is assured
7630 that the message is sent only once per client.
7632 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7633 lib/silcutil/silcutil.[ch] as silc_format function. The new
7634 function is generic and is used by server as well, not only by
7635 the logging routines.
7637 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7638 the provided version string was not acceptable. Added new function:
7639 silc_ske_check_version into lib/silcske/silcske.h. The function
7640 must be implemented by the application (client or server) and it
7641 does not reside in the SKE library. The function checks the version
7642 string remote end sent.
7644 * Added back pointers (to opaque context and to SilcSocketConnection)
7645 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7647 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7648 duplicate packet context structure.
7650 * Changed `notify' client operation to send same arguments as client
7651 receives from server except for ID's. ID's are mapped to correct
7652 ID entry and that is returned. Also, if channel entry is not sent
7653 by server but the notify is for channel the channel entry is sent
7654 to application (otherwise application doesn't know that it is for
7655 channel (library gets it from packet's Destination ID)).
7657 * Added silc_client_remove_from_channels into client library to
7658 remove a client from all channels it has joined to. Used when
7659 received SIGNOFF notify from server. Added also new function
7660 silc_client_replace_from_channels to replace old ID entry with
7661 new ID entry on all channels. Used when received NICK_CHANGE
7664 * Fixed ID Cache list handling in silc_idlist_get_client in
7665 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7666 to get (or query) client by ID.
7668 * Updated TODO list.
7670 * Added connection authentication status message defined by the
7671 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7672 support for these into the code in client and server side.
7674 * Added generic function silc_client_send_command to send any command
7675 with variable argument list. Application should use this function
7676 to send commands if the command functions provided by the library
7677 does not suite for the application's user interface needs.
7679 * Added new `failure' client operation. Application is notified about
7680 received failure packet if client is executing a protocol. In this
7681 case the protocol's execution has failed.
7683 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7684 is required by the protocol.
7686 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7687 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7690 * Added status flag to SilcSKE object to indicate realtime status
7691 of the SKE protocol.
7693 * Application receives now exactly same command reply arguments as
7694 the library receives from server. However, if ID is received the
7695 corresponding ID entry is returned to the application (eg. Client
7696 ID is mapped to correct SilcClientEntry entry and that is returned).
7697 Changed command_reply client operation due to this change.
7699 * Changed all ID's in commands and in command replys as ID Payloads.
7700 Change affected both client and server side codes.
7702 All ID's sent in SILC network (with execption of ID's in SILC
7703 Packet header) are sent in ID Payload to support variable length
7706 * Server now notifies nick changes and notifies all clients on
7707 the channels about the new nickname (about the new Client ID,
7710 * Implemented CMODE command to change channel modes. Supports all
7711 channel modes defined by the protocol specs except ban and invite
7712 lists. (Also, private channel key mode is supported but support for
7713 setting private channel key in client is missing, thus, this mode
7714 has no effect on client side (except that server requires that the
7715 client uses private channel key and normal channel traffic does not
7718 Also, invite mode works per se, but INVITE command does not work
7719 yet correctly, so you can set channel as invite only channel but
7720 inviting clients to the channel does not work (it is yet to be
7721 thought what's the best way to do it).
7723 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7724 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7725 Implemented CUMODE command to change user's mode on the channel.
7726 Supports all modes defined by the protocol specs.
7728 * Added NAMES command reply to return users modes on the channel.
7730 * Removed unnecessary and slow ciphers from lib/silccrypt.
7732 * Set SO_KEEPALIVE option to connection sockets by default.
7734 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7736 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7737 redefined the Notify Payload into protocol specs.
7739 * Added silc_id_payload_parse_id to get ID directly from raw
7742 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7744 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7745 accept searching by Client ID as well.
7747 * Added support for LEAVE and SIGNOFF notify types in client library.
7749 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7750 to parse ID Payload from raw data.
7752 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7754 * Added flags parameter into silc_ske_assemble_security_properties
7755 function in lib/silcske/silcske.[ch].
7757 * Changed notify client operation to fit better for notify messages
7758 sent by server. The notify payload received from server is now
7759 passed to the application (after parsing it to SilcNotifyPayload).
7760 It is application's responsibility to retrieve the arguments
7761 from the payload and show the message the way it wants. The message
7762 sent by server is implementation specific.
7764 * Changed public keys to comply with the protocol specification.
7765 Old public keys are not supported anymore and are not compatible.
7767 * Removed nickname from Channel Payload as the latest draft removed
7768 it. The client must resolve the nickname from the NAMES command
7769 reply received when it joined the channel.
7771 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7773 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7775 * Fixed some errors in protocol specification drafts.
7777 * Created lib/silccore/silcnotify.c to implement Notify Payload
7778 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7779 generic payloads described by protocol specifications. The file
7780 includes implementations for ID Payload and Argument Payload.
7782 * Changed Command Payload implementation to use the new Argument
7783 Payload. Changed command_xxxx_payload to command_payload_xxxx
7784 to comply with SILC coding conventions.
7786 * Added suppport for Argument Payload handling in Notify Payload
7787 implementation as protocol requires it. Added the new support
7788 into server and client lib as well.
7790 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7792 * Added support for multiple nicknames on same channel. [n] is
7793 added locally to the nickname if there are more than one same
7794 nicknames on the channel.
7796 * Server now sends all nicknames that matched WHOIS request.
7797 Client also shows the list received from server.
7799 * Added TOPIC command to client side. User can now set and show
7800 current topic on channel.
7802 * Added MOTD command to client and server. Also, server sends the
7803 motd when client connects to the server.
7805 * Changed version strings to comply ISO 8601.
7807 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7809 * Fixed protocol error handling in client library. It should now
7810 cope even if the SKE fails for some reason.
7812 * Made new protocol specification drafts for submitting to IETF.
7814 * Implemented TOPIC command to server in silcd/command.c.
7816 * Added two new notify types into lib/silccore/silcnotify.h:
7817 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7818 notify nickname change and topic setting/change on a channel.
7820 * API change of command_reply operation in client library. The
7821 application gets now the status type received from server as well.
7823 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7825 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7827 * Cras fixed and optimized the packet handling even further and
7828 it should work now. Minor change to the prototype of function
7829 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7831 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7833 * Added new function into lib/silcutil/silcschedule.[ch]:
7834 silc_schedule_with_fd to select() a specified fd. The function
7835 returns after timeout expires or data arrives or goes. The
7836 function is used by packet routines to wait that all data is
7837 received from network.
7839 * Fixed data reading from network in lib/silccore/silcpacket.c.
7840 The code now assures that all data is read from the fd and then
7841 continues packet processing. This was a bug fix since the code
7842 used to drop some data in some circumstances.
7844 * Added new function into lib/silcclient/client.[ch]:
7845 silc_client_start_key_exchange to start key exchange after
7846 connection has been established to server. The code internally
7847 now uses this funtion but its main purpose was to provide it
7848 for applications that perform their own connecting. After
7849 application has created a connection it merely calls this
7850 function to start the key exchange between client and server.
7851 The library takes care of everything else after that.
7853 Updated also lib/silcclient/README to explain the usage of
7856 * Do not send to application information that connection has
7857 been established. Application gets notified it by connect
7860 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7862 * Applied cras's patch to add silc_schedule_one function. The
7863 function runs scheduler once and returns.
7865 * Fixed the scheduler after cras messed it up. The timeout
7866 handling works now as it's supposed to work.
7868 * Added into lib/silccore/ silcnotify.h to include notify
7869 message types support. Changed silc_server_send_notify*
7870 functions, in server.[ch], to support those new notify types.
7871 Added the support for the notify types into client library,
7872 as well. Added new notify client operation into ops.h in
7875 * Changed silc_server_packet_send_to_channel to send normal
7876 packets instead of just channel message packets. The function
7877 is now used to send the notify packets to channels. It is not
7878 used to send channel message packets anymore, as server never
7881 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7882 va_arg()s as it seems to require it nowadays. I guess, if SILC
7883 is compiled with older va_arg() the new code should work anyway.
7885 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7887 * Splitted core library. Core library (lib/silccore) includes
7888 now only SILC protocol specific core (and common) components.
7889 Created new utility library (lib/silcutil) that includes more
7890 generic purpose stuff. The stuff for util library was taken
7891 from the old core library. This was minor and easy split.
7893 * Created SILC Client Library (lib/silcclient) that includes
7894 implementation of the SILC client without user interface. This
7895 was major move from silc/ directory. The code has been changed
7896 so that it is transparent towards the user interface. The
7897 silc/ directory includes now the same user interface as before
7898 and it uses the new client library. Read lib/silcclient/README.
7899 Basicly, the client library performs everything else related
7900 to SILC except user interface handling. Also, configuration
7901 files are considered to be part of user interface and library
7902 does not handle them.
7904 This change also changed a lot of structures, function naming etc.
7905 Most important change was that SilcClientWindow object was
7906 renamed to SilcClientConnection in the client library. Created
7907 also new file lib/silcclient/ops.h. Also added new files
7908 silc/local_command.[ch] and silc/client_ops.[ch].
7910 All these changes were made to make it easier for user interface
7911 designers to create what ever user interface for the SILC client
7914 It is also expected that the server will be moved to lib
7915 directory as well and SILC Server Library will be created;
7916 sometimes in the future.
7918 * Removed Local commands from lib/silccore/silccommand.h as
7919 they are application specific and new client library does not
7920 handle any of those anymore.
7922 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7923 old client implementation in silc/.
7925 * Added support for callback functions in SILC_LOG_* macros.
7926 Application can now set its own callbacks that will be called
7927 instead of using the default functions that will always print
7928 the debug messages to stderr (or stdout). Also, debugging can
7929 now be disabled by setting silc_debug to FALSE and re-enabled by
7930 setting it to TRUE. Note, that logging will still work even
7931 if debugging is disabled.
7933 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7934 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7935 silc_log_reset_debug_callbacks.
7937 * To enable debugging in silc client one must give now -d
7938 option on command line.
7940 * Changed silc_schedule_init to automatically allocate task queues
7941 if they are not allocated before calling it.
7943 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7945 * Added GMP 3.1 into math library.
7947 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7949 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7950 a channel in SILC network. The packet is used by servers and
7951 routers to notify other routers that user has left a channel.
7952 This little feature was missing until now. Added the feature
7953 to protocol specification as well.
7955 Added functions: silc_server_send_remove_channel_user and
7956 silc_server_remove_channel_user into server.[ch].
7958 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7959 lib/silccore/silcpacket.h. However, they are not implemented
7962 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7964 * Fixed joining to a channel and sending channel messages
7965 between server and router. The channel message sending should
7966 now work inside a cell.
7968 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7970 * Fixed the private message sending between server and router.
7971 The private message sending should now work inside a cell.
7973 * Added silc_server_replace_id into server.[ch] to replace
7974 existing ID in the SILC network.
7976 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7977 and silc_idlist_replace_server_id into idlist.[ch] in server.
7979 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7981 * Fixed the server to server connections. Server can again now
7982 connect to router. Router to router connections probably does
7985 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7987 * Added dynamic protocol registering support. Now protocols can
7988 registered and unregistered on the fly. Patch by cras.
7990 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7992 * Added lib/contrib directory to hold routines that some platforms
7993 don't have but are needed by SILC.
7995 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7996 into lin/contrib to provide getopt() and getopt_long() for
7997 those who don't have it.
7999 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8001 * Added AWAY command to client. When away message is set and
8002 client receives a private message packet the client automatically
8003 replies to the sender with the away message.
8005 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8006 bug seemed to be the cause of recent problems when compiling
8009 * Added version detection support to SKE protocol specification
8010 and added the new changes to the SKE implementation as well.
8011 There were other minor changes in the SKE protocol as well.
8013 Many changes in lib/silcske/silcske.[ch] and in
8014 lib/silcske/payload.[ch].
8016 * Added ^U functionality, clear input line. Patch from cras.
8018 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8020 * Mainly small bugfixes on core library. Fixed some debugging
8021 logging and buffer overflow in silclog.c.
8023 * Updated config.sub and config.guess on the distribution tree.
8025 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8027 * Added command lagging support in server. Client may execute
8028 commands now only once in two seconds.
8030 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8032 * Optimized packet reception. MAC computation and checking is now
8033 also more optimized. A lot previously duplicated code is now
8034 used as generic by both client and server.
8036 * Fixed key pair generation in clientutil.c
8038 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8040 * Added into lib/silccore/silcbufutil.[ch] new function;
8041 silc_buffer_realloc.
8043 * Moved generic packet sending/encryption functions to
8044 lib/silccore/silcpacket.[ch] from client and server. Some
8045 rewriting of the functions.
8047 * Moved all generic packet reception/decryption functions to
8048 lib/silccore/silcpacket.[ch] from client and server. The
8049 packet processing is now much cleaner in both client and server.
8050 These were major changes in both client and server.
8052 * Created many common functions in server to do packet sending.
8053 Previously code were duplicated a lot, this has been removed
8056 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8058 * Rewrote major parts of the ID cache system. Don't know
8059 whether it is better now or not but at least the API is more
8062 * Major rewrite on ID cache stuff on client because of the ID
8063 cache API changes. Added idlist.c to client.
8065 * Also major rewrite on ID cache stuff on server as well.
8066 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8067 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8068 in hand, instead they are all put into the ID cache system now.
8069 All server_idlist_* routines uses ID cache now instead of
8070 traversing its own lists (those lists does not exist anymore).
8071 SilcIDList though still exists. Also, SilcXXXEntry's are
8074 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8076 * Finally made the SKE implementation compliant to the protocol
8077 specification. All mp integers are now binary encoded as
8078 opposed being HEX encoded.
8080 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8083 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8084 functions: silc_[encode/decode]_pem. Also added function
8085 silc_encode_pem_file to PEM encode with newlines ('\n') for
8088 * SILC public keys are now encoded either PEM or binary. Same
8089 option is for private keys as well. By default private keys
8090 are binary encoded and public keys PEM encoded. Silly HEX
8091 encoding were removed.
8093 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8094 function to create fingerprints.
8096 * Fixed a bug in SHA1; does not change the original data anymore.
8098 * Partly implemented INFO command on client and server side.
8099 Fixed CLEAR command. Changes to SERVER command; show current
8100 server(s) when giving command without arguments. Added
8101 VERSION command to client.
8103 * Added check to server that unregistered connections cannot
8104 execute commands (unless it is specificly allowed).
8106 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8108 * Fixed screen refresh.
8110 * Fixed channel joining bug from client. On some circumstances
8111 client tried to join to a channel it had already joined.
8113 * Added public key verification process into client's protocol.c.
8114 The client now verifies the public key from user and saves
8115 it into ~./silc/serverkeys/ directory.
8117 Added into: clientutil.[ch]: silc_client_verify_server_key.
8119 * Changed SKE protocol's silc_ske_initiator_finish function
8120 to accept callback function that verifies the received public
8121 key. Removed old silc_ske_verify_public_key function.
8123 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8125 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8126 silc_pkcs_private_key[_data]_set.
8128 * Made the password and public authentication more cleaner in
8129 server's protocol.c.
8131 * Removed historic and obsolete protocol `channel_auth' from
8132 both client and server.
8134 * Removed wrong way of sending command status messages from
8135 server to client in server's command.c. The old way violated
8136 protocol specification.
8138 Changes to silccore/silccommand.[ch]: removed
8139 silc_command_encode_status_payload -> not needed anymore,
8140 changed silc_command_encode_payload_va to accept extra
8141 argument on variable argument list. The argument type must
8142 now be provided to the function. Also, added new function:
8143 silc_command_encode_reply_payload_va which is same as
8144 normal command_encode_payload_va except command status type
8145 is provided as extra argument.
8147 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8149 * Added ~./silc directory handling. The directory includes the
8150 public and private keys for the client.
8152 Added silc_client_check_silc_dir, silc_client_create_identifier
8153 and silc_client_load_keys.
8155 * Implemented SILC protocol compliant public key. Added public
8156 and private key saving to and loading from files.
8158 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8159 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8160 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8161 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8162 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8164 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8165 silc_pkcs_load_[public/private]_key.
8167 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8169 * Added silc_server_get_route (route.[ch]) to get connection
8170 data for the fastest route for given ID.
8172 * Implemented INVITE command on client and server. The command
8173 were re-defined in the SILC Protocol Specification and the
8174 implementation now complies with the specification.
8176 * Implemented PING command on client and server.
8178 * Implemented NAMES command on client and server. The server side
8179 supports currently only normal server not router server yet.
8180 Some changes to NAMES definition in SILC protocol specification.
8182 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8184 * Implemented LEAVE command on client and server.
8186 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8187 again. This change was made to the protocol as well. Server
8188 should not violate the protocol specification anymore.
8190 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8192 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8193 was tested. SOCKS4 was not but should work anyway.
