1 Fri Apr 19 09:02:20 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added service support to SILC protocol. Added new command
4 SILC_COMMAND_SERVICE. Updated the protocol specs and the
5 core library. Services are not implemented in server or
6 client for now. Protocol TODO #20. Affected files are
7 lib/silccore/silcstatus.h, lib/silccore/silccommand.h.
9 Thu Apr 18 14:09:51 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
11 * Added silc_mime_parse function to parse MIME headers.
12 Affected files are lib/silcutil/silcstruti.[ch].
14 * Added MIME header parsing in Irssi SILC Client. It displays
15 all textual MIME objects, others it ignores. Affected file
16 is irssi/src/silc/core/clien_ops.c.
18 Wed Apr 17 22:07:59 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
20 * Fixed a bug in the pid writing function, which couldn't be
21 written in a root-owned directory.
23 Tue Apr 16 09:34:40 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
25 * Defined that channel message to unknown Channel ID must
26 cause SILC_NOTIFY_TYPE_ERROR notify message to the sender.
27 Updated the protocol specs and the code in server. The
28 affected file is silcd/packet_receive.c.
30 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
32 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
33 that it is used to send error notifys if error occurs during
34 some SILC packet processing, except commands. The error
35 types are same as for command reply types. Defined that
36 if private message is sent to unknown Client ID the error
37 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
38 Updated the protocol specs and code. Affected files are
39 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
40 lib/silcclient/client_notify.c, silcd/packet_receive.c,
41 and irssi/src/silc/core/client_ops.c. Renamed the
42 SilcCommandStatus to SilcStatus.
44 * Defined the use of extra WHOIS attributes in WHOIS command.
45 The <Requested Attributes> (defined in a separate document)
46 can be used to request additional information about user
47 not returned by standard WHOIS command. Defined that server
48 can send WHOIS command directly to client. Client provides
49 the requested attributes to the server. Updated the protocol
50 specs. Protocol TODO #4. Implementation is not done yet
53 * Renamed function silc_client_command_status_message to
54 silc_client_status_message. Affected files are

73 options to the server. Affected files silcd/serverconfig.[ch],
74 silcd/command.c and silcd/packet_receive.c.
76 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
78 * Added resolve_cmd_ident field to the SilcClientEntry structure
79 too so that if the entry is for example being resolved so
80 another command may attach to the same pending command reply
81 without requiring to resolve the same entry again. Added
82 support for adding multiple pending commands for one
83 command idenfier. Affected files lib/silcclient/command.[ch],
84 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
86 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
88 * Defined that server receives WHOIS command reply for private
89 and secret channels too. Updated protocol specs and the
90 code in server. Affected file silcd/command.c.
92 * Defined <channel user mode list> argument to WHOIS command
93 reply for returning user modes on the channels. The
94 channel list now doesn't include the user mode anymore but the
95 actual channel mode. Updated protocol specs and the code in
96 client and server. Affected files are silcd/command_reply.c,
97 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
98 and lib/silcclient/command_reply.c.
100 * Save the channels list in WHOIS command reply in normal server
101 so that WHOIS always shows joined channels also in normal
102 server and not just on router. Affected file is
103 silcd/command_reply.c.
105 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
107 * Defined that server receives USERS command reply for private
108 and secret channels too. Updated protocol specs and the
109 code in server. Affected file silcd/command.c.
111 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
113 * Changed the UMODE's mode mask argument to be optional. If
114 not provided then the command merely returns the current mode
115 mask to the client. Updated protocol specs and the server.
116 Affected file is silcd/command.c.
118 * Added SILC session detachment/resuming support. It is possible
119 to detach by closing the network connection and then re-connect
120 and resume to the old client session. Added DETACHED user
121 mode that server will set for detached client. Added new
122 packet RESUME_CLIENT which is used to perform the resuming
123 process. Added DETACH command. Updated the protocol specs,
124 core library, client and server. Protocol TODO #22. Very
125 many affected files around the tree.
127 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
129 * Changed the CMODE's mode mask argument to be optional. If
130 not provided then the command merely returns the current mode
131 mask to the client. Updated protocol specs and the server.
132 Affected file is silcd/command.c.
134 * Changed the Killer's Client ID in KILLED notify to be just
135 any ID payload since router server is allowed to kill as well.
136 Updated protocol specs, client libary and server. Affected
137 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
138 and irssi/src/silc/core/client_ops.c.
140 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
142 * Added new user modes ANONYMOUS for special anonymous servers
143 that may set the mode for client, and BLOCK_PRIVMSG which
144 client may set to block incoming private messages unless the
145 Private Message Key flag is set (using private keys to protect
146 private messages). Updated protocol specs and code in client
147 and server and core library. Protocol TODO #23. Affected
148 files are lib/silccore/silcmode.h, silcd/server.[ch],
149 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
150 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
152 * Added new channel user mode BLOCK_MESSAGES which the client
153 may set to itself to tell server not send channel messages.
154 Other packets such as channel key packets are still sent.
155 Protocol TODO #23. Updated the protocol specs, client and
156 server. Affected files are lib/silccore/silcmode.h,
157 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
158 lib/silcutil/silcutil.c, silcd/command.c, and
161 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
163 * Redefined the Status Payload to include now two 8 bit fields,
164 instead of one 16 bit field. This now makes it possible to
165 send list of errors. Updated the protocol specs and the code
166 in core library, client library and server. Protocol TODO #1.
167 Affected files are lib/silccore/silccommand.[ch],
168 lib/silcclient/command_reply.[ch], silcd/command.c,
169 silcd/command_reply.c and silcd/packet_receive.[ch].
171 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
173 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
174 must be handled by the application and should tell the application
175 that an error message was already printed, and it should print the
176 config coords (line, filename, ...). Affected files are
177 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
179 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
180 server config parsing code more readable.
182 Fixed a bug in the fetch_logging() config callback.
184 Affected files is silcd/serverconfig.c.
186 * Drop root privileges when started in foreground. Don't drop them
187 if debugging also. Affected file is silcd/silcd.c.
189 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
191 * Added more IM-like features by introducing new user modes
192 for setting various presence information. Added new modes:
193 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
194 specs and code. Protocol TODO #19. Affected files are
195 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
196 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
198 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
200 * Added STATS command to the protocol after all, to return
201 various statistical information about the network. It can
202 be used by clients to retrieve statistical information, and
203 servers may use it to to fetch cell and network wide
204 statistics from router. Updated the protocol specs and
205 implemented it to the server. Protocol TODO #16.
206 Affected files are lib/silccore/silccommand, silcd/command.[ch],
207 silcd/command_reply.[ch].
209 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
211 * The LIST command reply in client libary now adds new channel
212 entry if the returned channel doesn't exist yet in cache,
213 and returns the channel entry to the application in the
214 command_reply client operation. Affected file is
215 lib/silcclient/command_reply.c.
217 * Changed the channel message payload's MAC generation to
218 include the IV in the MAC as well. This way all relevant
219 parts of the channel message payload are authenticated also
220 with the channel message MAC (and not only by packet MAC).
221 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
222 Affected file is lib/silccore/silcchannel.c.
224 * Fixed the SKE to save the remote version, since the
225 silc_ske_parse_version mistakenly checked wrong version,
226 after it replaced the start payload. Affected files are
227 lib/silcske/silcske.[ch].
229 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
231 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
232 string utility functions. Added there also new functions
233 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
234 Affected files lib/silcutil/silcstrutil.[ch].
236 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
237 files are lib/silcutil/silcstrutil.[ch].
239 * Defined that the security property fields in SKE SHOULD be
240 UTF-8 encoded, defined that version string MUST be US-ASCII
241 encoded, defined that passphrases sent in connection
242 authentication protocol MUST be UTF-8 encoded. Implemented
243 these to the client and server. Defined also that other
244 passphrases sent in the protocol MUST be UTF-8 encoded.
245 Affected files are lib/silcske/silcske.c,
246 lib/silcclient/protocol.c, silcd/protocol.c,
247 silcd/serverconfig.c, and lib/silccore/silcauth.c.
249 * Changed the silc_client_close_connection interface to not
250 need the SilcSocketConnection which should not be visible
251 to application. Affected files are lib/silcclient/client.c
252 and lib/silcclient/silcclient.h.
254 * Rewrote the text for Private Message Key Payload in the
255 protocol specification. Protocol TODO #11.
257 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
259 * Upgraded the protocol version to 1.1, updated protocol specs
262 * Added the nickname as new argument to NICK_CHANGE notify and
263 added it to protocol specs and implemented it to client and
264 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
265 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
266 lib/silcclient/client_notify.c.

269 it to protocol specs and implemented it to client and server.
270 Protocol TODO #13. Affected files are silcd/command.c,
271 silcd/packet_receive.c, packet_send.[ch],
272 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
273 The killer's client entry is now returned to application in
274 the `notify' client operation.
276 * Fixed the Max Argument fields that had too large value set
277 in the protocol specs. Protocol TODO #14.
279 * Added the LEAVE command reply to return the ID of parted
280 channel. Updated protocol specs and implemented it to the
281 client and server. Protocol TODO #15. Affected files are
282 silcd/command.c, lib/silcclient/command_reply.c. The channel
283 entry is now returned to application in the `command_reply'
286 * Rewrote the version SKE version checking in client libary
287 and in server to use the silc_parse_version_string. Affected
288 files are lib/silcclient/protocol.c, silcd/protocol.c.
290 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
291 commands that was missing it, and updated protocol specs and
292 the server implementation. Protocol TODO #10. The affected
293 file is silcd/command.c.
295 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
296 generic reply to a generic request (REQUEST flag), and
297 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
298 way. A draft-riikonen-silc-flags-payloads-00.txt is written
299 to define the payload for DATA flag. Added the flags to
300 the implementation. Protocol TODO #9. Affected file is
301 lib/silccore/silcchannel.h.
303 Changed the client library to return the message length
304 to application as well in the channel_message and private_message
305 client operations. Affected files are
306 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
307 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
308 and lib/silcclient/client_ops_example.c.
310 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
311 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
312 the channel. Updated protocol specs and impelemented this
313 to client and server. Protocol TODO #6. Affected files are
314 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
315 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
317 Added new options m and M to CMODE command in Irssi SILC
318 client to set these modes.
320 * Deprecated all administrative commands from SILC protocol
321 since they are highly implementation specific commands.
322 Updated protocol specs. Moved the old commands in
323 implementations to private range of command types. Affected
324 files are silcd/command.c, lib/silcclient/command.c and
325 lib/silcclient/command_reply.c. Protocol TODO #8.
327 * Fixed a bug in server where sending unknown command crashes
328 the server. Affected file silcd/command.c.
330 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
332 * Added SILC_PROTOCOLVERSION macro to check protocol version
333 of a socket connection. The affected file is
334 lib/silcutil/silcsockconn.h.
336 * Added better error logging in rekey protocol. Affected file
339 * Do not check public key types in SKE during rekey. Affected
340 file lib/silcske/payload.c.
342 * Fixed the rekey protocol with PFS, which was totally broken.
343 Affected file silcd/protocol.c.
345 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
347 * Some client implementations quit network by doing first LEAVE
348 and then immediately SIGNOFF (like Bombyx). We now do check
349 after a short time after LEAVE notify and check whether the
350 client is still valid after LEAVE, and if not we remove it from
351 cache. Affected file is lib/silcclient/client_notify.c.
353 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
355 * Merged version 1.1.4 of zlib. Even if it not currently in use,
356 it's good not to have security holes here.
358 * Fixed a negative refcount situtuation for the config context.
359 Affected file is silcd/serverconfig.c.
361 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
363 * ROBOdoc documented lib/silcutil/silcutil.h.
365 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
367 * Optimized even more the SilcPacketContext structure. Now
368 totally saved 16 bytes of memory per context after optimization.
369 Affected files are lib/silccore/silcpacket.[ch].
371 * Made strict checks for valid SILC IDs. Affected file is
372 lib/silccore/silcid.c.
374 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
376 * Changed the object argument for silc_cipher_register,
377 silc_hash_register, silc_hmac_register and silc_pkcs_register
378 to const. Affected files are lib/silccrypt/silccipher.[ch],
379 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
381 * Changed the silc_get_username and silc_get_real_name to
382 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
384 * Fixed the Irssi SILC Client to use the silc_get_username and
385 silc_get_real_name insted of glib routines since the glib
386 routines only corrupt stack. Fixes the Irssi SILC to work in
387 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
389 * Fixed the Irssi to not use g_get_home_dir since it crashes
390 or returns garbage on cygwin and corrupts stack. Added function
391 get_home_dir to Irssi routines. Affected files are
392 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
394 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
396 * Made some structure optimizations. SFTP memory FS MemFSEntry
397 entry structure. Optimized SilcTask structure. Optimized
398 SilcPacketContext structure.
400 Affected files lib/silcsftp/sftp_fs_memory.c,
401 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
403 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
405 * And yet again reverted back the config thing since Johnny
406 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
409 * Fixed memory leaks from config object. Affected files are
410 silcd/serverconfig.[ch].
412 * Added support for adding new connections to the server in rehash.
413 After rehash they take effect.
415 Added support for changing the maximum allowed connections in
416 rehash. The number can grow but going smaller is not supported.
418 Added function silc_server_num_sockets_by_remote to the
419 silcd/server_util.[ch].
421 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
423 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
425 * Added preliminary checking during config parsing for a valid
426 public/private key and removed further checks in the code.
427 Affected files are silcd/serverconfig.[ch], server.c.
429 * Moved functions silc_server_drop() and silc_server_daemonise()
430 from server.c to silcd.c since they are stricly related to
431 the application activity.
433 * Reverted a small part of the automatic ref/unref since
434 it caused a double unref in some situations. Affected
435 files are silcd/silcd.[ch], server.c, serverconfig.c.
437 * Added some .cvsignore files in the lib directory.
439 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
441 * Fixed silc_net_gethostbyaddr to correctly resolve by
442 address. Affected file lib/silcutil/silcnet.c.
444 * Fixed the notify relaying to client. The HMAC to be used
445 with relayed packets ws wrong and caused decryption failure
446 at the client end. Affected file is silcd/packet_receive.c.
448 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
450 * Created new branch silc_protocol_1_0_branch.
452 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
454 * Changed the silc_server_config_* routines to be SilcServer
455 independent. They are now officially application specific code
456 and not part of generic server implementation. Affected files
457 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
459 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
461 * Added automatic referencing of config context in the
462 silc_server_config_alloc, and automatic unreferencing in the
463 silc_server_config_destroy. Affected files are
464 silcd/serverconfig.[ch], silcd/silcd.c.
466 * Fixed the silc_log_quick handling in the logging routines.
467 It didn't log quickly when it was TRUE. Affected file is
468 lib/silcutil/silclog.c. Also the flush delay was set even
469 if it was 0 in config file. Affected file is
470 silcd/serverconfig.c.
472 * Added support for changing key pair of the server in rehash.
473 Affected file silcd/server.c.
475 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
477 * Fixed the TOPIC_SET notify to not cras. It changed the topic
478 too early, before getting the channel entry. Affected file
479 is silcd/packet_receive.c.
481 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
483 * Added functions silc_server_config_[ref/unref], these are used
484 to prevent that the config object is destroyed.
486 No longer directly affect global variables silc_log_quick and
487 silc_log_delay, they are first cached inside the config object
488 and then applied with silc_server_config_setlogfiles().
490 silc_server_config_set_defaults() is now internal to
491 serverconfig.c, there are no reasons to show this internal stuff
494 Affected files are silcd/serverconfig.[ch].
496 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
497 fprintf's to stderr, since some code may be executed again after
498 the server went into the background. Affected files are
501 * Added rehash support. Added function silc_server_rehash() that
502 will perform all the basic tasks of the rehashing procedure.
504 * Added command line option `-x, --hexdump'. This will enable the
505 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
506 The option `--hexdump' implies `--debug'.
508 * Fixed a bad bug in the logging APIs (silcutil library) where
509 the application would crash after calling silc_log_reset_all().
511 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
513 * Fixed the KICKED notify handling in client library to
514 correctly remove the channel and all entries from the
515 channel when I was kicked. This bug crashed the client.
517 Fixed yet another but in KICKED notify handling to remove
518 the kicked client correctly from the channel.
520 Affected file is lib/silcclient/client_notify.c.
522 * Fixed a minor bug in looking up correct client entry
523 in KICKED notify in server. Affected file is
524 silcd/packet_receive.c.
526 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
527 sources correctly to distribution. Fixes --with-gmp option.
529 * Removed the manual rehashing from ID Cache, and changed it
530 to use the SILC Hash Table's auto rehash feature. Affected
531 file is lib/silccore/silcidcache.c.
533 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
535 * Fixed a bug in the silc_client_nickname_format function that
536 handles the multiple same nickname formatting. Two clients
537 with same nickname caused problems after the first one left
538 and rejoined. It didn't format the nickname correctly.
539 Affected file is lib/silcclient/idlist.c.
541 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
543 * Don't change the topic if olod topic is same as new one.
544 Affected file is silcd/packet_receive.c.
546 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
548 * Added cross-reference support to the SILC Documentation
549 generator. All types across all HTML files are now cross-
550 referenced. Affected files util/robodoc/generator.c and
551 scripts/silcdoc/silcdoc.
553 * Added file lib/silcutil/silctypes.h to include all the
554 arithmetic type definitions and some macros. Removed
555 includes/bitmove.h and moved macros to silctypes.h.
557 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
559 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
561 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
563 * Added `type' argument to silc_id_payload_parse_id function which
564 now returns the type of the ID to the sent pointer. Affected
565 file is lib/silccore/silcid.[ch].
567 * Added check for CMODE_CHANGE notify type that mode change is
568 allowed by the sender. Affected file silcd/packet_receive.c.
570 * Added check for CUMODE_CHANGE notify type that mode change is
571 allowed by the sender. Affected file silcd/packet_receive.c.
572 Added the ID type as CUMODE_CHANGE notify type as argument
573 to the `notify' client operation. Affected files are
574 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
576 * Added function silc_client_add_server to the client library.
577 Added support for resolving also channel and server info when
578 received unknown entity in notify packet. Affected files are
579 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
581 * Added function silc_command_get_status to return the command
582 status from the command reply's argument payload. Affected files
583 are lib/silccore/silccommand.[ch].
585 * Added check for KICKED notify type that the kicking is
586 allowed by the client. Affected file silcd/packet_receive.c.
588 * Created function silc_get_input which can be used to get input
589 (echo on or off) from user on command line. Affected files are
590 lib/silcutil/silcutil.[ch].
592 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
594 * Optimized silc_server_packet_relay_to_channel function.
595 Added new function silc_channel_message_payload_encrypt which
596 can be called directly if channel message payload needs to
597 be encrypted and is already encoded (no need to call _encode
598 function). Packet relaying is now done by router without any
599 extra memory allocations. Affected files are
600 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
603 * Fixed the INVITE notify handling. It took wrong arguments
604 as invite list and invite delete. Affected file is
605 silcd/packet_receive.c.
607 * Added check for TOPIC_SET notify type that the topic change is
608 allowed by the client. Affected file silcd/packet_receive.c.
610 * Added check for INVITE notify type that inviting is allowed by
611 the client. Affected file silcd/packet_receive.c.
613 * Changed the silc_server_client_on_channel to return the
614 SilcChannelClientEntry as well. Moved the function
615 silc_server_check_cmode_rights to server_util.[ch].
616 Affected files are silcd/server_util.[ch], silcd/command.c.
618 * Added function silc_server_check_umode_rights to check whether
619 changing client's user mode is allowed. Added check for
620 UMODE_CHANGE notify type that the umode change is allowed
621 by the client. Affected files are silcd/server_util.[ch],
622 silcd/packet_receive.c and silcd/command.c.
624 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
626 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
627 ID length. It ignored that ID can be IPv6 based as well.
628 Affected file lib/silccore/silcpacket.h.
630 * Fixed the silc_id_id2str and silc_id_str2id to take the
631 IPv6 address offset's into consideration. Affecte file is
632 lib/silccore/silcid.c.
634 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Fixed the internal Unix scheduler functions to check for
637 NULL context they may receive. The affected file is
638 lib/silcutil/unix/silcunixschedule.c.
640 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
642 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
643 can specify different directory with --home command line
644 parameter. Affected files irssi/src/silc/core/client_ops.c,
647 * SILC-specific commands aren't now executed if the active server
648 isn't of SILC-type, so there won't be problems with having
649 IRC and SILC protocol support in same client. Affected files
650 irssi/src/silc/core/silc-channels.c, silc-servers.c,
653 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
655 * Improved the signal support in SILC Schedule. Added new
656 function silc_schedule_signal_call which is used by application
657 to mark a signal to be called. It is now safe to perform
658 any kind of tasks in signal callbacks since it is guaranteed
659 that the application specified signal callback is called
660 after the signal is over. Affected files are
661 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
663 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
665 * Added `name' field to SilcChannelPrivateKey to represent
666 application given name for the key. Moved also the context from
667 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
668 Added the `name' argument also to the function
669 silc_client_add_channel_private_key.
671 Added function silc_client_current_channel_private_key to set the
672 current channel private key in use.
674 Added "change" command to KEY command which can be used to change
675 the current channel private key. Bound the command also to
678 Also affected files lib/silcclient/client_channel.c,
679 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
681 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
683 * Added silc_rng_get_byte_fast function in to the
684 lib/silccrypt/silcrng.[ch].
686 * Changed the interface of silc_packet_assemble and the
687 silc_packet_send_prepare. If silc_packet_assmble is now
688 called the application does not call silc_packet_send_prepare
689 because the library will call it automatically. These
690 interfaces now also return a reference to the outgoing buffer
691 which includes the assembled packet, which the application can
692 use to encrypt the packet.
694 Affected files are lib/silccore/silcpacket.[ch],
695 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
696 silcd/packet_send.c, server_backup.c and packet_receive.c.
698 * Fixed a packet sending bug on very high load, where outgoing
699 packet queue wasn't handled correctly and packets got corrupted.
700 Affected files are lib/silcutil/*/silc*sockconn.c,
701 lib/silcclient/client.c and silcd/server.c.
703 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
705 * Added macro SILC_PACKET_DATALEN which can be used during
706 packet assembling to check whether the data to be added to
707 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
708 len is truncated until it fits it.
710 Added checks for maximum length of channel message payload and
711 private message payload also.
713 Added checks for maximum packet length in server and in
716 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
717 lib/silcclient/client.c, lib/silccore/silcchannel.c and
718 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
719 lib/silcclient/client_prvmsg.c.
721 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
723 * Added silc_server_packet_queue_purge call to the
724 silc_server_disconnect_remote to assure that all data in the
725 queue before disconnecting is sent to the network. Affected
728 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
730 * Added the deleting of server's own ID cache entry to the
731 silc_server_free function. Free also everything else that
732 has been allocated in silc_server_init. The affected file
735 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
737 * Added functions silc_parse_version_string, silc_version_to_num,
738 and silc_ske_parse_version to parse SILC protocol style version
739 strings. Affected files lib/silcutil/silcutil.[ch] and
740 lib/silcske/silcske.[ch].
742 * Added new configuration params: version_protocol, version_software
743 and version_software_vendor to specify what version the remote
744 host must at least be to be able to connect to server. The vendor
745 string can be regex matched too. Added new function
746 silc_server_connection_allowed to check maximum number of allowed
747 connections, and allowed versions for incoming connections.
748 Affected files are silcd/server.c, server_util.[ch] and
751 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
753 * Added preliminary support for signals in scheduler. The
754 signals we care about are now blocked always when the scheduler
755 is locked. This way we can synchronise the use of signal with
756 scheduler. It is guaranteed that when signal occurs the scheduler
757 is not locked, and thus new tasks can be safely added to the
760 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
761 to silc_schedule_internal_init and silc_schedule_internal_uninit.
762 Added new platform specific routines
763 silc_schedule_internal_signals_[un]block and
764 silc_schedule_internal_signal_[un]register.
766 Added new functions to SILC Schedule API:
767 silc_schedule_signal_[un]register. Each signal that application
768 is going to use should be registered to the scheduler.
770 Affected files are lib/silcutil/silcschedule.[ch],
771 lib/silcutil/*/silc*schedule.c.
773 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
775 * Check for unauthenticated client and server in the
776 silc_server_new_client and silc_server_new_server functions.
777 Affected file silcd/packet_receive.c.
779 * Added function silc_string_is_ascii to check whether given
780 string is 7-bit ASCII string. Affected files are
781 lib/silcutil/silcutil.[ch].
783 * Added function silc_id_is_valid_server_id into the
784 silcd/serverid.c and added checking for valid Server ID's in
785 silc_server_new_server. The Server ID must always be based
786 on the server's public IP address.
788 * Added logging of DISCONNECT packet message in the server.
789 Affected file silcd/server.c.
791 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
793 * Changed all library interfaces that use Global RNG to also
794 accept SilcRng as argument. Affected files are
795 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
796 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
797 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
798 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
801 * Added function silc_pkcs_generate_key to the
802 lib/silccrypt/silcpkcs.[ch] for applications so that they
803 don't need to do pkcs->pkcs->init calls anymore.
805 * Remove SilcSocketConnection from the SFTP API since it really
806 wasn't needed there. The application has the information
807 saved in its contexts anyway and the SFTP layer doesn't need
808 know about it. Affected files lib/silcsft/silcsftp.h and
809 lib/silcsftp/sftp_[server/client].c.
811 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
812 The SilcSimContext is not SilcSim.
814 * Fixed possible buffer overflows in silc_id_render in the
815 lib/silcutil/silcutil.c.
817 * On EPOC the global crypto module lists are not used at all
818 in the crypto library. Added support for using the constant
819 algorithm list on EPOC. Affected files are
820 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
823 * Fixed the handling of third parameter of KICKED notify, since
824 it was mistakenly updated to SILC Protocol 1.0 even though it
825 is to be included in 1.1. Since it is not in 1.0 it is not
826 mandatory, and this fix now handles it only if it is provided,
827 and it is not error if it is not provided. Affected file
828 lib/silcclient/client_notify.c.
830 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
832 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
833 client. Affected file irssi/src/silc/core/client_ops.c.
835 * Merged with Irssi 0.8.4 from irssi.org CVS.
837 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
839 * Check for valid socket connection in client entries before
840 sending any messages. Fixes a crash, but doesn't fix some
841 other underlaying bug that is lurking there. Affected
842 file silcd/packet_send.c.
844 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
846 * $usermode, $cumode and $cumode_space expandos shouldn't do
847 anything with non-SILC server records. Affected file
848 irssi/src/silc/core/silc-expandos.c
850 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
852 * Fixed the silc_net_check_[host/local]_by_sock to support
853 IPv6 bound sockets as well. Now they can return IPv6 addresses
854 as well. Affected file lib/silcutil/silcnet.c.
856 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
857 Affected lib/silcutil/unix/silcunixnet.c.
859 * Fixed ID rendering (at least on some platforms, not NetBSD)
860 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
862 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
864 * Added silc_hash_public_key and silc_hash_public_key_compare
865 functions to be used with SilcHashTable. They can be used to
866 hash public keys and compare public keys in hash table. Affected
867 file lib/silcutil/silcutil.[ch].
869 * Added support for specifying multiple public keys for Client
870 connection section in server configuration file. This makes it
871 possible to accept multiple public keys from same host, or to
872 make a section that accepts any incoming host, and have the
873 accepted public keys listed in the section.
875 Added functions silc_sever_[find/get]_public_key, added the
876 support for this actually to all connection sections but only
877 the Client section is currently allowed to specify multiple
880 Affected files are silcd/server.c, server_internal.h,
881 command.c, protocol.c, server_util.[ch], packet_receive.c.
883 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
885 * Merged Irssi 0.8.2 from irssi.org CVS.
887 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
889 * If silc_debug is TRUE, also output standard logging messages
890 to stderr with the debug output.
892 Made silc_log_reset_all() flushing all channels before returning.
893 Also fixed some documentation typos.
895 Affected files are lib/silcutil/silclog.[ch].
897 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
899 * Fixed the server to check correctly the amount of connections
900 from single host, by checking also the type of the connection.
901 Fixed also the comparison of number of connections and number
902 of allowed connections. Affected files are silcd/server.c,
905 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
907 * Fixed the USERS command reply to save the user's mode on the
908 channel as well. Fixed JOIN command reply to check whether a
909 client is on channel already and not join it twice. Affected
910 file lib/silcclient/command_reply.c.
912 * Added new file silc-expandos.c into irssi/silc/core/ to return
913 various stuff for various signal for the statusbar etc. updating.
914 Now Irssi SILC client prints channel user modes etc. on the
917 * The user mode (like server/router operator changes) is now shown
918 on the Irssi SILC client's statusbar. The affected files are
919 irssi/src/silc/core/client_ops.c, silc-expandos.c.
921 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
923 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
924 to SILC_SCHEDULE_[UN]LOCK macros.
926 * Added more error printing to logs in server code. Affected
927 files silcd/server.c and silcd/protocol.c.
929 * Fixed -S option parsing in Irssi SILC Client. Affected file
930 irssi/src/silc/core/silc-core.c.
932 * Added silc_buffer_alloc_size function. Affected file is
933 lib/silcutil/silcbuffer.h.
935 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
937 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
938 constants. Affected files in
939 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
942 * Changed the internal SFTP Memory FS table to const. Affected
943 file lib/silcsftp/sftp_fs_memory.c.
945 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
947 * Fixed the buffer formatting and unformatting routines to
948 check the size of 64 bits types with sizeof(). Affected
949 file is lib/silcutil/silcbuffmt.c.
951 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
953 * Removed 0.6.x backwards support.
955 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
957 * Changed all integer type names:
958 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
959 to avoid collisions with other libraries using same type names
962 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
964 * Added `prefer_ipv6' argument to the functions
965 silc_net_gethostbyname[_async]. If it is TRUE it will return
966 IPv6 address over IPv4. If FALSE IPv4 address is returned
967 even if IPv6 address was found. Affected files
968 lib/silcutil/silcnet.[ch].
970 * Added support silc_net_create_connection[_async] to fallback
971 to IPv4 address if IPv6 address could not be used (like if
972 it doesn't work on a specific system). Affected file in
973 lib/silcutil/unix/silcunixnet.c.
975 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
977 * Added silc_schedule_reinit function to do the enlarging
978 of the max tasks handling capabilities of the scheduler.
979 Affected files lib/silcutil/silcschedule.[ch].
981 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
983 * Added automatic extern "C" { ... } for C++ compilers so the
984 application does not need to define them. Affected file
985 includes/silcincludes.h.
987 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
988 old name went against naming convention. Applications now
989 include "silcclient.h" instead of "clientlibincludes.h".
990 Removed includes/clientlibincludes.h, it is redundant now.
992 * Renamed includes/version.h to silcversion.h.
994 * Added really preliminary support for OS/2 into the util
995 library. Only thread & mutex API is implemented, others
996 are still to be implemented. Created the lib/silcutil/os2/
997 directory. Created also file includes/silcos2.h.
999 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1001 * Added preliminary BeOS support into the util library.
1002 Created lib/silcutil/beos/, and implemented all the needed
1003 functions to support SILC on BeOS. Created also file
1004 includes/silcbeos.h.
1006 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1008 * Added proper initializations to silc's irssi code, so it's
1009 now possible to load it as module. Affected files
1010 irssi/src/silc/core/silc-core.c,
1011 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1013 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1015 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into

1019 docs from all kinds of filenames. Affected files are
1020 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1022 * ROBOdoc documented lib/silcutil/silcmemory.h.
1023 Added also new function silc_memdup.
1025 * Removed lib/silcutil/silcbufutil.h and moved those routines
1026 to the lib/silcutil/silcbuffer.h.
1028 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1030 * Added `user_count' to the SilcChannelEntry which now tells the
1031 number of users on the channel. The user count is now saved
1032 in normal server of global channels as well. Affected files
1033 silcd/server.c, idlist.h, packet_receive.c and command.c.
1035 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1036 include file utility functions.
1038 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1039 instead of calling directly OS routines.

1052 the SKE interface a bit.
1054 * Fixed padding problem in PKCS#1. The padding was not actually
1055 random since the random number generator was used incorrectly.
1056 This security bug affects only when encrypting with PKCS#1, and
1057 it is not currently used at all in SILC. SILC only use signing
1058 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1115 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1117 * Fixed command line parameter handling. All SILC initialization
1118 is now done in silc_core_init() which also fixes autoconnecting
1121 Affected files irssi/src/silc/core/silc-core.c,
1122 irssi/src/fe-text/silc.c.
1124 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1126 * Added new configuration options and blocks:
1127 keepalive_secs, reconnect_count, reconnect_interval,
1128 reconnect_interval_max, reconnect_keep_trying and
1129 require_reverser_lookup. Added ConnectionParam block, and
1130 implemented the connection parameters when connecting as
1131 initiator and when accepting connections as responder.

1143 the connection configuration object from the SilcServerConnection
1144 object instead of finding it during the connecting phase.
1145 Added the configuration object to SilcServerConnection struct.
1146 Affected files silcd/server_internal.h, server.c.
1148 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1150 * Add the client on channel after it was resolved at the
1151 channel message receiving, and it was not already on the
1152 channel. Affected file lib/silcclient/client_channel.c.
1154 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1170 authentication to be set at the same time.
1172 Added `prefer_passphrase_auth' setting in config file which
1173 can be used to set to prefer passwd auth if both passwd and
1174 public key is set. If not set, public key is preferred.
1175 This has effect only when being initiator (responder will try
1178 Added support for authentication with passphrase and public key
1179 at the same time. The passphrase is tried first always since
1180 it is faster to check.
1182 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1184 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1186 * Merged the new SILC Config library, with the server parsing

1230 * Fixed the file transfer's key agreement payload to include
1231 zero port also if the hostname is NULL because it could not
1234 Call file transfer monitor callback now also if error occurs
1235 during key agreement protocol.
1237 Changed the silc_client_file_send interface to return the
1238 SilcClientFileError instead of session id. The session ID
1239 is returned into pointer provided as argument.
1241 Check that the file exists locally before sending the
1242 file transfer request at all.
1244 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1246 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1247 error than can occur while key agreement protocol. Affected
1248 file lib/silcclient/silcapi.h.

1256 file lib/silcutil/silclog.c.
1258 * Fixed the channel message payload decryption in the function
1259 silc_channel_message_payload_decrypt to not modify the original
1260 buffer before it is verified that the message decrypted
1261 correctly. Otherwise, next time it is called with correct
1262 channel key it won't encrypt since the payload is corrupted.
1263 Affected file lib/silccore/silcchannel.c.
1265 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1277 * Fixed a bug in hash table internal routine for traversing
1278 the table with foreach callback. The current entry may
1279 become invalid in the callback but it was referenced after
1280 the callback returned.
1282 Do not allow auto rehashing of hash table during the
1283 silc_hash_table_foreach operation, for same reasons as it is
1284 not allowed for SilcHashTableList. Affected files are
1285 lib/silcutil/silchashtable.[ch].
1287 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1293 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1295 * Fixed private message handling. It used some old code that
1296 caused the client to crash. Affecte file is
1297 lib/silcclient/client_prvmsg.c.
1299 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1301 * Added function silc_client_add_channel,
1302 silc_client_replace_channel_id, and removed functions
1303 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1304 from client library.
1306 * Added cross reference of the joined channels to the
1307 SilcClientEntry, and changed the SilcChannelEntry's
1308 users list to SilcHashTable. The affected files are
1309 lib/silcclient/idlist.[ch].
1311 * Fixed a bug in hash table tarversing. While the hash table
1312 is traversed with SilcHashTableList the table must not be
1313 rehashed. It is now guaranteed that auto rehashable tables
1314 are not rehashed while tarversing the list. Also defined that
1315 silc_hash_table_rehash must not be called while tarversing
1316 the table. Added function silc_hash_table_list_reset that must
1317 be called after the tarversing is over. The affected files are
1318 lib/silcutil/silchashtable.[ch].
1320 * Changed all hash table traversing to call the new
1321 silc_hash_table_list_reset in server and in client library.
1323 * Added function silc_client_on_channel to return the
1324 SilcChannelUser entry if the specified client entry is joined
1325 on the specified channel. This is exported to application as
1326 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1328 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1330 * Fixed founder regaining problem with JOIN command on normal
1331 server. The notify for mode change must be sent always and
1332 not only if !cmd->pending. Affected file silcd/command.c.
1334 * Fixed the WHOWAS command's reply sending to support the
1335 lists correctly. Affected file silcd/command.c.
1337 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1339 * When sending JOIN command to router for processing the
1340 sender's old command identifier was not saved back to the
1341 sender's command context, fixed now. The affected file is
1344 * Create the key in JOIN command of the router did not return
1345 the channel key, added check for this. Affected file is
1348 * Fixed a channel ID update bug in JOIN command reply. Do
1349 not directly upgrade the ID but call the function
1350 silc_idlist_replace_channel_id if the ID was changed.
1351 Affected file silcd/command_reply.c.
1353 * Fixed memory leaks from command calling if it would fail.
1354 Affected file silcd/command.c.

1366 * Removed TRQ from lib/trq, not needed anymore.
1368 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1369 with server connections. Later this will be configurable
1370 in config file after new config file is done. Affected file
1373 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1375 * Fixed a crash in server related to channel announcements.
1376 Affected file silcd/server.c.
1378 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1380 * Fixed memory leaks in silc_server_create_new_channel*
1381 functions. Affected file silcd/server.c.
1383 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1384 which ID was changed. This way the router will send the
1385 user list for the channel again, and server won't be in
1386 desync in some rare circumstances. Affected file is
1387 silcd/packet_receive.c.
1389 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1404 file for application programmers to quickly start using
1405 the SilcClientOperation functions in their application.
1406 Updated the lib/silcclient/README as well to tell about this
1407 nice file made available.
1409 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1411 * Call silc_server_remove_from_channels when removing client
1412 entry when NO_SUCH_CLIENT_ID was received. Affected file

1417 * Added server & router operator statistics updating. Affected
1418 file silcd/packet_receive.c and silcd/command.c.
1420 * Fixed the SERVER_SIGNOFF notify handling on normal server
1421 not to save the history information for clients. Same was
1422 fixed earlier in remove_clients_by_server function, but not
1423 here. Affected file silcd/packet_receive.c.
1425 * Raised the default connection-retry count from 4 to 7 in
1426 server. Affected file silcd/server.h.
1428 * Cancel any possible reconnect timeouts when we start the
1429 key exchange. Affected file silcd/server.c.
1431 * Do not reconnect on connection failure when SCONNECT was
1432 given. Affected files silcd/server.[ch].
1434 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1436 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1438 * Fixed the NICK command to always give the unformatted
1439 nickname to the one giving the NICK command. If unformatted
1440 nickname is cached already it will be formatted and the
1441 local entry will always get the unformatted nickname.
1442 Affected file lib/silcclient/idlist.c.
1444 * Fixed some double frees from client library commands.
1445 Affected file is lib/silcclient/command.c.
1447 * Fixed CUMODE command in server to assure that no one can
1448 change founder's mode than the founder itself, there was a
1449 little bug. Affected file silcd/command.c.
1451 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1453 * Removed the SilcClientCommandDestructor from the client
1454 libary, it is not needed anymore. Affected files are
1455 lib/silcclient/silcapi.h, command[_reply].[ch],
1456 client_notify, idlist.c.
1458 * Fixed GETKEY command to first resolve client, and then
1459 resolve the server only if the client was not found, instead
1460 of resolving both at the same time. Affected file is
1461 lib/silcclient/command.c.
1463 * Added silc_client_start_key_exchange_cb and lookup the
1464 remote hostname and IP address before starting the key
1465 exchange with server. The affected file is
1466 lib/silcclient/client.c.
1468 * The server's public key is now saved using the IP address
1469 of the server and not the servername for the filename.
1470 The hostname public key filename is checked as an fall back
1471 method if the IP address based filename is not found.
1473 Fixed the GETKEY command to save the fetched server key
1474 in correct filename.
1476 Print the remote server's hostname now when new key is
1477 received during connection process. Affected file is
1478 irssi/src/silc/core/client_ops.c.
1480 * Return always our own public key to the client if it asks
1481 for it with GETKEY command. Affected file silcd/command.c.
1483 * Removed the use_auto_addr variable from default config
1484 file since it was in wrong section. Affected file is
1487 * Fixed TOPIC_CHANGE notification to not route it when it
1488 was sent using silc_server_send_notify_to_channel function.
1489 Affected file silcd/command.c.
1491 * Fixed silc_server_send_notify_kicked to send the kicker's
1492 Client ID also, it was missing. Affected files are
1493 silcd/command.c, silcd/packet_send.[ch].
1495 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1497 * Do not save client history information in SERVER_SIGNOFF.
1498 Fixes the bug in normal server that it does not detect
1499 the client becoming valid after the server becomes back
1500 online. Affected file silcd/server_util.c.
1502 * Added `sock_error' field into the SilcSocketConnection
1503 context. When error occurs during socket operation (read
1504 or write) the error is saved. Added also new function
1505 silc_socket_get_error to return human readable socket error
1506 message. Affected files are lib/silcutil/silcsockconn.[ch],
1507 lib/silcutil/unix/silcunixsockconn.c, and
1508 lib/silcutil/win32/silcwin32sockconn.c.
1510 * The server now prints the socket error message in the
1511 signoff for client. Affected file silcd/server.c.
1513 * Fixed the `created' channel information sending from router
1514 to server in JOIN command. Checks now whether the channel
1515 really was created or not and set it according that.
1517 Fixed the JOIN command to use the client entry's current
1518 ID during the joining procedure instead of the one it sent
1519 in the command (it is checked though), since it can change
1520 between the packet processing and command processing, and
1521 would just case unnecessary pain in the client end. Affected
1522 file silcd/command.c.
1524 * Fixed a channel key payload sending to use correct channel
1525 ID when the server was forced to change the channel's ID by
1526 router. Router sent the key payload with the old Channel ID.
1527 Affected file silcd/packet_receive.c.
1529 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1531 * Call silc_server_save_channel_key only if the key payload
1532 was provided in the JOIN command's command reply. Affected
1533 file silcd/command_reply.c.
1535 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1537 * Fixed silc_mp_sizeinbase to return the value correctly with
1538 MPI. Affected file lib/silcmath/mp_mpi.c.
1540 * Fixed the stop_server signal to correctly stop the scheduler
1541 and gracefully stop the server when SIGTERM or SIGINT signals
1542 are received. Affected file silcd/silcd.c.
1544 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1546 * Simple handling of TERM and HUP signals. Also added some log
1547 flushing call around. Affected file is
1550 * Fixed small bugs in silclog.c. Now buffering output will take
1551 effect after 10 seconds since startup: This will ensure that
1552 no important startup messages are lost. Also output redirection
1553 will preserve original format ([Date] [Type] message).
1554 Affected file is lib/silcutil/silclog.c.
1556 * Added two options to the config file, in the logging section:
1557 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1558 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1560 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1562 * Do not print the warning about log files not being initialized
1563 more than once to avoid excess logging. Affected file is
1564 lib/silcutil/silclog.c.
1566 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1567 the SIM copying in make install in Makefile.am.pre.
1569 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1571 * Rewritten silclog APIs. Globally interesting changes follows:
1572 silc_log_set_files() changed to silc_log_set_file().
1573 silc_log_set_callbacks() changed to silc_log_set_callback().
1574 ROBOdoc documented silclog header file.
1575 SilcLogCb now returns bool to wether inihibit the default
1576 handler or not (to keep the old behaviour return always TRUE).
1577 The new APIs should also fix the problem of the
1578 silcd_error.log file that was written in the current directory.
1581 Log files streams will remain opened after silc_log_set_file()
1582 call, means less CPU usage notably on high traffic servers.
1583 File streams are now full buffered, and flushed to the disk
1584 every 5 minutes, lesses HD activity and CPU usage.
1585 Messages can be redirected, allowing admins to configure
1586 one single logfile for all server messages.
1587 the silc_log_quick global variable to activate fast-logging.
1588 Affected files lib/silcutil/silclog.[ch]
1590 * Changed some code to conform new silclog APIs. Affected
1591 files are doc/example_silcd.conf.in, silcd/server.c
1592 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1595 * Fixed a memory leak that could occur in some situations.
1596 Affected file silcd/serverconfig.c.
1598 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1600 * Added the silc_client_del_client to remove the client from
1601 all channels as well. Affected file lib/silcclient/idlist.c.
1603 * Fixed the client library to correctly remove the client
1604 from all channels when the client entry is being destroyed.
1605 Affected file lib/silcclient/client_notify.c, command.c.
1607 * Added auto-nicking support to the client library. If the
1608 applicatio now sets client->nickname it will be sent to the
1609 server after connecting by the library. This way for example
1610 SILCNICK (or IRCNICK) environment variables will have effect
1611 and always change the nickname automatically to whatever
1612 it is wanted. Affected file lib/silcclient/client.[ch].
1614 * Renamed silc_server_command_bad_chars to the
1615 silc_server_name_bad_chars and moved it to the
1616 silcd/server_util.[ch]. Added also new function
1617 silc_server_name_modify_bad to return nickname that
1618 includes bad characters as new nickname without those
1619 bad characters. This check and modify is now used in
1620 silc_server_new_client when the username is initially set
1621 as nickname, so it must be checked to be valid nickname.
1622 Affected file silcd/packet_receive.c.
1624 * The nickname length is now taken from the packet for real
1625 and not trusted to strlen() since it clearly can return
1626 wrong length for nickname including bad characters. This
1627 also applies to channel names. Affected file silcd/command.c.
1629 * Removed the lib/silcsilm/modules directory. Modules are now
1630 compiled into the lib/silcsim. Fixed the copying of the
1631 modules to follow symbolic links in Makefile.am.pre.
1633 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1635 * Fixed silc_string_regexify list creation. Fixes bugs with
1636 BAN and INVITE commands in server. The affected file is
1637 lib/silcutil/unix/silcunixutil.c.
1639 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Removed the command destructor entirely from the server's
1642 command and command reply routines. It is not needed, and
1643 its usage was buggy and caused crashes. Affected files are
1644 silcd/command[_reply].[ch].
1646 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1648 * Cancel protocol and NULL sock->protocol if timeout
1649 occurred during protocol. Affected file silcd/server.c.
1651 * Cancel protocol timeouts always before calling the final
1652 callback, to assure that after final callback is called
1653 no other state will be called for the protocol anymore.
1654 Affected file silcd/protocol.c.
1656 * Print error log if incoming connection configuration could
1657 not be found. Affected file silcd/server.c.
1659 * Fixed JOIN command to correctly save the founder mode
1660 to the client on normal SILC server, when the channel
1661 was created by the router. Affected file silcd/command.c.
1663 * Fixed LIST command (hopefully) to send correct reply
1664 packets. Affected file silcd/command.c.
1666 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * The silc_packet_receive_process now returns FALSE if the
1669 read data was invalid packet, and TRUE if it was ok.
1671 The server now checks that if unauthenticated connection
1672 sends data and its processing fails the server will close
1673 the connection since it could be a malicious flooder.
1675 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1677 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1679 * Make sure the warning about error opening a log file is
1680 printed only once and not everytime it fails (produces
1681 too much useless log). Affected file lib/silcutil/silclog.c.
1683 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1685 * Made the silc_server_daemonise() function more readable.
1686 Affected file silcd/server.c.
1688 * Pid file is now optional, the user may comment it out from
1689 the config file. Removed define SILC_SERVER_PID_FILE, we
1690 don't need a default any longer. Affected file
1691 configure.in.pre, lib/Makefile.am.pre.
1693 * Make some use of the pid file. The server now dies at startup
1694 if it detects a valid pid file on his path. The server would
1695 die anyway in this circumstance, because of the bind() failure.
1696 Affected file silcd/silcd.c.
1698 * No longer compiling lib/dotconf.
1700 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1702 * Fixed JOIN command parsing not to crash. Affected file
1703 lib/silcclient/command.c.
1705 * Fied the NICK_CHANGE notify to add the new client entry
1706 even it is resolved. This removes an <[unknown]> nick
1707 thingy bug in the client. Affected file is
1708 lib/silcclient/client_notify.c.
1710 * Do not try to allocate 0 bytes (efence does not like it)
1711 in lib/silccore/silccomand.c when encoding payload.
1713 * Do not take IRCNICK as nickname in Irssi SILC client since
1714 it is not possible to set nickname before hand connecting
1715 the server (TODO has an entry about adding auto-nicking
1718 * Changed the silc_server_command_pending to check whether
1719 there already exists an pending entry with the specified
1720 command, command identifier and pending callback. This is
1721 to fix IDENTIFY and WHOIS related crashes that may register
1722 multiple pending commands with same identifier. Affected
1723 file silcd/command.c.
1725 * Fixed the server to reconnect to the router even if it
1726 was already reconnecting and EOF was received. This to
1727 fix a possibility that the server wouldn't ever try to
1728 auto-reconnect to the router. Affected file silcd/server.c.
1730 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1732 * Fixed the server's password authentication to use the
1733 length of the locally saved password, and not the one
1734 sent in the packet. Affected file silcd/protocol.c.
1736 * Fixed same password authentication problem in the
1737 Authentication Payload handling routines in
1738 lib/silccore/silcauth.c.
1740 * Yet another password authentication problem fixed with
1741 channel password handling in silcd/command.c.
1743 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1745 * If first character of string in silc_parse_userfqdn is '@'
1746 then do not parse it. Affected file is
1747 lib/silcutil/silcutil.c.
1749 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1751 * Fixed minor bug in IDENTIFY command reply sending, which
1752 caused various weird problems during JOIN when it was
1753 resolving names for users. Affected file silcd/command.c.
1755 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1757 * Fixed the IDENTIFY command reply sending to chech better valid
1758 clients. It was possible to send incomplete list of replies.
1759 Affected file silcd/command.c.
1761 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Added silc_client_command[s]_[un]register functions now to
1764 dynamically register the commands in client library. Removed
1765 the static table of commands. This allows the client library
1766 to call commands without causing the application to know about
1767 what commands library has called.
1769 Removed the INFO command reply kludge to detect when the command
1770 was called by library. Now library use its own command reply
1771 function for INFO command.
1773 Added function silc_client_command_call to call a command.
1774 Application can use it to call command, not access the structure
1777 Now all commands that are sent by the client library (not
1778 explicitly sent by application) use own command reply functions.
1780 Affected files around lib/silcclient/ and in
1781 irssi/src/silc/core/.
1783 * Fixed the WHOIS command reply sending to chech better valid
1784 clients. It was possible to send incomplete list of replies.
1786 Fixed the WHOIS and IDENTIFY to send the request to router
1787 if normal server did not do it and did not find any results.
1789 Affected file silcd/command.c.
1791 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1793 * Moved the internal data from SilcClient context into its
1794 own file, not accesible to application. Affected files
1795 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1796 and other files in client library.
1798 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1800 * Added doc/examples installation target in Makefile.am.pre.
1803 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1806 commands the found client entry will be removed from the
1807 cache, after notifying application about the error. Affected
1808 file lib/silcclient/command_reply.c.
1810 * Changed the /MSG to check for exact nickname user gave, and
1811 not let `nick' match `nick@host' if it is only one found. Now,
1812 user must type the exact nickname (like nick@host2) even if
1813 there are no more than one same nicks found. This is to avoid
1814 a possibility of sending nickname to wrong nickname since
1815 `nick' could match `nick@host'. Affected file is
1816 irssi/src/core/silc-servers.c.
1818 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Do not print "you are now server operator" or similar when
1821 giving /away command. Affected files are
1822 irssi/src/silc/core/client_ops.c, silc-servers.h.
1824 * Made the silc_server_command_pending_error_check to send
1825 the same command reply payload it received back to the
1826 original sender of the command. This way all arguments
1827 that was received by the server will be received by the
1828 client too. Affected file silcd/command.c.
1830 * Added the silc_idcache_add to return the created cache entry
1831 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1833 * Add global clients to expire if they are not on any channel.
1834 This is because normal server will never know if they signoff
1835 if they are not on any channel. The cache expiry will take
1836 case of these entries. This is done by normal servers only.
1837 The affected files are silcd/command_reply.c,
1838 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1840 * If server receives invalid ID notification for WHOIS or
1841 IDENTIFY and the ID exists in the lists, it is removed.
1842 Affected file silcd/command_reply.c.
1844 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1845 in client then client entry that it matches is searched and
1846 the nickname is printed on the screen for user. Affected
1847 file irssi/src/silc/core/client_ops.c.
1849 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Use cache entry expire time in the LIST command reply to
1852 purge old entries from the cache after the LIST command
1853 reply has been received. This way we don't have non-existent
1854 entries in the cache for too long. Affected file is
1855 silcd/command_reply.c.
1857 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1859 * If we are normal server, and we've not resolved client info
1860 in WHOIS or IDENTIFY from router, and it is global client,
1861 we'll check whether it is on some channel. If it is not
1862 then we cannot be sure about its validity and will resolve it
1863 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1864 file silcd/command.c.
1866 * Search channel by name (if possible) rather than by ID
1867 in IDENTIFY command's command reply. Affected file is
1868 silcd/command_reply.c.
1870 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1872 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1873 Updated specs and implemented it. Affected file silcd/command.c,
1874 silcd/packet_send.c and silcd/packet_receive.c.
1876 * Implemented the <founder auth> payload handling in the JOIN
1877 command. If provided all conditions for channel joining
1878 except requirement to provide correct passphrase can be
1879 overrided by the channel founder. Updated the protocol specs.
1880 Affected file silcd/command.c.
1882 Added support for founder auth in JOIN command in client
1883 library. Fixed the parsing of the JOIN command now to support
1884 all options as they should be. The affected file is
1885 lib/silcclient/command.c.
1887 * Optimized the WHOIS and IDENTIFY commands to send the request
1888 to router only if it includes nicknames or other names. If
1889 they include only IDs then check the local cache first before
1890 routing. Affected file is silcd/command.c.
1892 * Added channels topic announcements. Affected file is
1893 silcd/packet_receive.c and silcd/server.c.
1895 * Fixed the silc_server_send_notify_topic_set to really destine
1896 the packet to channel. Affected file silcd/packet_send.c.
1898 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1899 library. Affected file lib/silcclient/client_notify.c.
1901 * Added UMODE announcements. Affected file silcd/server.c.
1903 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * Memory leak fixes in:
1907 lib/silcutil/silcsockconn.c
1908 lib/silcske/silcske.c
1909 lib/silcske/groups.c
1911 lib/silccrypt/silcpkcs.c
1912 lib/silccore/silccommand.c
1913 lib/silccore/silcidcache.c
1918 * ROBOdoc documented the lib/silcske/groups.h file and a
1919 bit changed the interface for better.
1921 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1923 * Update the client entry context in the ID cache after
1924 nick change. Affected file lib/silcclient/command.c.
1925 Fixes the CUMODE command when regaining founder privileges,
1926 and a little WHOIS problem.
1928 * Fixed silc_net_gethostbyname to correctly call the
1929 inet_ntop. Affected file lib/silcutil/silcnet.c.
1931 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1933 * Added IPv6 support checking to the configure.in.pre, added
1934 also --enable-ipv6 option to override the check. Affected
1935 file configure.in.pre.
1937 * The silc_thread_create now calls the start function
1938 directly if threads support is not compiled in. Removes
1939 ugly #ifdef's from generic code. Affected files are
1940 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1942 * Added silc_net_gethostby[name/addr]_async to asynchronously
1943 resolve. Affected files are lib/silcutil/silcnet.[ch].
1945 * Added support for rendering IPv6 based server, client and
1946 channel IDs. Affected file lib/silcutil/silcutil.c.
1948 * Added support for creating IPv6 based server IDs. Affected
1949 file is silcd/serverid.c.
1951 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1953 * Added silc_net_gethostby[addr/name] into the
1954 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1955 routines. Added silc_net_is_ip[4/6]. Affected file is
1956 lib/silcutil/unix/silcunixnet.c. All routines that take
1957 address as argument now supports both IPv4 and IPv6 addresses.
1959 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1961 * Fixed LIST command reply sending in server. Affected file
1964 * Server now sends the kicker's client ID in the KICK notify
1965 to the kicked client. Affected file silcd/command.c.
1967 * The client library now parses the kickers client ID and
1968 UI displays it. Affected files lib/silcclient/client_notify.c
1969 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1971 * Made all payload parsing function prototypes consistent.
1972 They all take now const unsigned char * and uint32 pair as
1973 the payload data instead of SilcBuffer. Changes all around
1974 the source tree. Other unsigned char* -> const unsigned char*
1975 changes around the tree as well.
1977 * Optimized SFTP client and server packet sending not to
1978 allocate new buffer for each packet but to recycle the
1979 first allocated buffer. Affected files are
1980 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1982 * Optimized the SFTP client to use SilcList instead of
1983 SilcDList for requests, because it is faster. Affected file
1984 is lib/silcsftp/sftp_client.c.
1986 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1987 into lib/silccore/silcid.[ch].
1989 Renamed silcpayload.[ch] into silcargument.[ch].
1991 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * If client entry is deleted with active key agreement
1994 session, abort the session.
1996 The silc_client_abort_key_agreement now calls the completion
1997 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1999 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2002 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2004 * Don't use __restrict in older GCC's. Affected file is
2005 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2007 * silc_net_localhost now attempts to reverse lookup the
2008 IP/hostname. Affected file lib/silcutil/silcnet.c.
2010 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2011 command. It can be used to gain founder privileges at
2012 the same time when joining the channel.
2014 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2015 kicker's client ID as well. Updated protocol specs.
2017 Defined that the server must send SILC_COMMAND_IDENTIFY
2018 command reply with error status to client who sent
2019 private message with invalid client ID.
2021 Updated the protocol specification.
2023 * Added silc_server_send_command_reply to send any
2024 command reply. Affected file silcd/packet_send.[ch].
2026 * Added silc_id_payload_encode_data to encode ID payload
2027 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2029 * The server now send IDENTIFY command reply with error
2030 status if client ID in private message is invalid. Affected
2031 file silcd/packet_receive.c.
2033 * Save the server key file with server's IP address in
2034 the filename instead of hostname. The affected file is
2035 irssi/src/silc/core/client_ops.c.
2037 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2039 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2042 * Added libtool support for compiling shared objects in
2043 lib/silcsim. Affected file configure.in.pre and
2044 lib/silcsim/Makefile.am. Original patch by cras.
2046 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Pid file configuration, and server's config file fixes
2049 patch by toma. Updated CREDITS file.
2051 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Fixed silc_client_channel_message to not try to decrypt
2054 the message twice if it resolved the destination client
2055 information. This could cause of dropping one channel
2056 message. Affected file lib/silcclient/client_channel.c.
2058 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2061 lib/silcclient/client.c. This function is used when the SILC
2062 Client is run under some other scheduler, or event loop or
2063 main loop. On GUI applications, for example this may be
2064 desired to used to run the client under the GUI application's
2065 main loop. Typically the GUI application would register an
2066 idle task that calls this function multiple times in a second
2067 to quickly process the SILC specific data.
2069 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2071 * Fixed silc_server_drop() for dropping the supplementary
2072 groups as well, this could cause a security hole on some
2075 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2080 * Write PID file after dropping privileges. Added -F option
2081 to run server on foreground. A patch by debolaz.
2082 Affected files silcd/server.c, silcd/silcd.c.
2084 * Fixed MOTD to return the MOTD file server name. Affected
2085 file silcd/command.c.
2087 * Added INFO command reply handling to the Irssi SILC Client.
2088 Affected file irssi/src/silc/core/client_ops.c.
2090 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2092 * Fixed the silc_idcache_list_* routines to really support
2093 the dynamic list. Fixes a crash. Affected file is
2094 lib/silccore/silcidcache.c.
2096 * Fixed the LIST command reply to really call LIST command's
2097 pending callbacks. Affected file silcd/command_reply.c.
2099 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * Update conn->local_entry->nickname after giving NICK
2102 command. Affected file lib/silcclient/command.c.
2104 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2106 * Added the [pid] option to the silcd configuration file
2108 Affected files: serverconfig.[ch] and silcd.c
2110 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Save fingerprint in WHOIS command reply in server.
2113 Affected file silcd/command_reply.c.
2115 * Fixed NICK commands pending callback registration.
2116 Affected file lib/silcclient/command.c.
2118 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Use ++server->cmd_ident when sending commands in server,
2121 instead of random number. Affected file silcd/command.c.
2123 * Fixed GETKEY command reply to call actually GETKEY pending
2124 command callbacks. Affected file silcd/command_reply.c.
2126 * A bit stricter check for nicknames. Check for same nickname
2127 in NICK command also. Affected file silcd/command.c.
2129 * Do not call INFO command everytime client ID changes, only
2130 during first connecting. Affected file lib/silcclient/client.c.
2132 * Set the new nickname only after successful command reply for
2133 NICK command is returned by server. Affected file
2134 lib/silcclient/command.c.
2136 * Remove nicknames from nicklist during server_signoff notify.
2137 Should fix /NAMES bit more. The affected file is
2138 irssi/src/silc/core/silc-channels.c.
2140 * Added `fingerprint' field to the SilcIDListData in the
2141 silcd/idlist.h to hold the fingerprint of the client's
2144 Send the fingerprint of the client's public key in WHOIS
2147 Affected files silcd/command.c, and silcd/idlist.[ch].
2149 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2150 create fingerprint from given data.
2152 * Show the fingerprint of the client's public key in WHOIS.
2153 Affected files irssi/src/module-formats.[ch] and
2154 irssi/src/silc/core/client_ops.c.
2156 * Format the multiple same nicknames also during JOIN and
2157 NICK_CHANGE notifys. Affected file is
2158 lib/silcclient/client_notify.c.
2160 * Do not print error on screen for invalid private message
2161 payload since it can come if someone is sending private
2162 messages with wrong key. Affected file
2163 lib/silccore/silcprivate.c.
2165 * Fixed multiple concurrent /PING crash. Affected file
2166 lib/silcclient/command.c.
2168 * Changed the wrong ID encoding. All IP addresses must be
2169 in MSB first order in encoded format. They were encoded
2170 wrong and was in LSB format. Affected files are
2171 silcd/serverid.c, lib/silcutil/silcutil.c.
2173 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2175 * Call the `connect' client operation through the scheduler
2176 in case of error. Affected file lib/silcclient/client.c.
2178 * Call the `failure' client operation even if the error
2179 occurred locally during a protocol. Affected file is
2180 lib/silcclient/protocol.c.
2182 * Added support of sending LIST command to router from normal
2183 server. This way normal server can get list of all channels
2184 in the network too. Fixed the channel list sending in the
2185 server too. Affected files are silcd/command.c, and
2186 silcd/command_reply.[ch].
2188 * Added silc_server_update_channels_by_server and
2189 silc_server_remove_channels_by_server. They are used during
2190 disconnection of primary router and in backup router protocol.
2191 Affected file silcd/server_util.[ch], silcd/server.c and
2192 silcd/server_backup.c.
2194 * Fixed channel adding to global list in IDENTIFY command
2195 reply in server. Affected file silcd/command_reply.c.
2197 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2199 * If the incoming packet type is REKEY or REKEY_DONE process
2200 that packet always synchronously. Fixes yet another MAC
2201 failed error on slow (dialup) connections. Affected file
2202 lib/silcclient/client.c and silcd/server.c.
2204 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2206 * Call check_version SKE callback for initiator too. Affected
2207 file lib/silcske/silcske.c.
2209 * Implemented fix for security hole found in the SKE that was
2210 fixed in the specification few days back; the initiator's
2211 public key is now added to the HASH value computation.
2212 Added backwards support for the old way of doing it too, for
2213 old clients and old servers. Affected file is
2214 lib/silcske/silcske.c.
2216 * Enabled mutual authentication by default in SKE. If initiator
2217 is not providing mutual authentication the responder will
2218 force it. This will provide the proof of posession of the
2219 private key for responder. The affected files are
2220 lib/silcclient/protocol.c and silcd/protocol.c.
2222 * Do not cache anymore the server's public key during SKE.
2223 We do mutual authentication so the proof of posession of
2224 private key is done, and if the server is authenticated in
2225 conn auth protocol with public key we must have the public
2226 key already. Affected file silcd/protocol.c.
2228 * Added new global debug variable: silc_debug_hexdump. If
2229 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2230 file lib/silcutil/silclog.[ch].
2232 * Fixed compilation warning due to char * -> const char *.
2233 Affected files lib/silcutil/silcnet.h, and
2234 lib/silccore/silcauth.[ch].
2236 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2238 * Fixed CMODE command when new channel key was created. If
2239 the creation failed the old key was removed. Next time giving
2240 same command would crash the server since the old key was
2241 freed already. Affected file silcd/command.c.
2243 * Fixed the silc_server_announce_get_channels to not crash
2244 on reconnect. Affected file silcd/server.c.
2246 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Added silc_log_set_debug_string function to set a regex
2249 string to match for debug output. Only the function names,
2250 or filenames matching the given debug string is actually
2251 printed. This way it is possible to filter out those debug
2252 strings that user is not interested in.
2254 Fixed a bug in silc_string_regexify.
2256 Affected files lib/silcutil/silclog.[ch], and
2257 lib/silcutil/unix/silcunixutil.c.
2259 * Changed the -d options in both server and Irssi SILC client
2260 to take the debug string as argument. Affected files
2261 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2263 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * Added silc_hash_babbleprint to create a Bubble Babble
2266 Encoded fingerprint. The encoding is developed by Antti
2267 Huima (draft-huima-babble-01.txt), and it creates human
2268 readable strings out of binary data. Affected file
2269 lib/silccrypt/silchash.[ch].
2271 * Print the babble print now in addition of fingerprint as well
2272 in Irssi SILC client. Affected files are
2273 irssi/src/fe-common/silc/module-formats.[ch],
2274 irssi/src/fe-common/silc/core/client_ops.c.
2276 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2278 * Fixed a security problem found in SKE. The initiator's
2279 public key too is now added to the HASH hash value creation
2280 which is signed by the responder to create the SIGN value.
2281 This will prevent anyone in the middle to lie to the responder
2282 about the initiator's public key. If this is done now, the
2283 man in the middle will get caught. Updated the protocol
2286 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Better installation directory handling. Configure module
2289 paths and other paths automatically to example_silc* files
2290 in doc/. A patch by toma.
2292 * Fixed compiler warning from MPI library, and from SILC RNG.
2295 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2296 It can be configured with ./configure. A patch by toma.
2298 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Find correct make to use in prepare-clean. A patch by
2301 toma. Affected file prepare-clean.
2303 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2305 * Added irssi variables use_auto_addr, auto_bind_ip,
2306 auto_bind_port and auto_public_ip.
2308 * Changed the interface for silc_client_send_key_agreement
2309 in lib/silcclient/silcapi.h
2313 irssi/src/silc/core/silc-core.c
2315 lib/silcclient/silcapi.h
2316 irssi/src/silc/core/silc-channels.c
2317 lib/silcclient/client_keyagr.c
2320 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2322 * Added silc_pkcs_public_key_compare to compare two
2323 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2325 * Check that the client who set the founder mode on the
2326 channel is the same client that is giving the founder
2327 mode to itself. It is done by comparing the saved public
2328 key (it is saved even in the authentication is passphrase).
2329 Affected file silcd/command.c.
2331 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2333 * Do not process packet for disconnected socket connection.
2334 Affected file lib/silccore/silcpacket.c.
2336 * Process the DISCONNECT packet through scheduler in the
2337 client library. Affected file lib/silcclient/client.c.
2339 * Fixed the silc_client_packet_parse to not to increase
2340 the packet sequence number if the conn->sock and the
2341 current socket connection is not same. This can happen
2342 for example during key agreement when the conn includes
2343 multiple socket connections (listeners). Affected file
2344 lib/silcclient/client.c.
2346 * The sender of the file transfer request now provides also
2347 the pointer (listener) for the key exchange protocol. If
2348 the listener cannot be created then it sends empty key
2349 agreement and lets the receiver provide the listener.
2351 Added `local_ip' and `local_port' arguments to the
2352 silc_client_file_send. If they are provided they are used,
2353 if not then it will attempt to find local IP address, if
2354 not found or bind fails then the remote client will provide
2357 Affected files are lib/silcclient/client_ftp.c and
2358 lib/silcclient/silcapi.h.
2360 * Extended the FILE SEND command to support defining the
2361 local IP and port for key exchange listener. They are
2362 optional. Affected file irssi/src/silc/core/silc-servers.c.
2364 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Defined to WHOIS command reply the sending of fingerprint
2367 of the client's public key (if the proof of posession of the
2368 corresponding private key is verified by the server).
2369 Updated to the protocol specification.
2371 * Added support of receiving the client's public key's
2372 fingerprint in command reply in client library. Affected
2373 file is lib/silcclient/command_reply.c, and
2374 lib/silcclient/idlist.[ch].
2376 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2378 * Do not send over 128 chars long nickname to the server
2379 in NICK command. Affected file lib/silcclient/command.c.
2381 * Do not send over 256 chars long channel names to the server
2382 in JOIN command. Affected file lib/silcclient/command.c.
2384 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2386 * Assure that silc_server_close_connection cannot be called
2387 twice for same socket context. Affected file is
2390 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2392 * Send error message to application if opening file for
2393 writing during file transfer fails. Affected file is
2394 lib/silcclient/client_ftp.c.
2396 Remove all file transfer sessions for a client that we're
2397 removing from ID cache.
2399 Affected file is lib/silcclient/client_ftp.c.
2401 * Fixed silc_net_addr2bin to return correct address. Affected
2402 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2404 * Fixed file transfer session removing on signoff notify.
2405 Affected file irssi/src/silc/core/silc-servers.c.
2407 * Added the SilcClientFileError to be returned in the monitor
2408 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2409 Affected file lib/silcclient/silcapi.h.
2411 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Fixed a crash in silc_client_ftp_free_sessions and
2414 silc_client_ftp_session_free_client. Affected file
2415 lib/silcclient/client_ftp.c.
2417 * Added `disabled' field in the SilcChannelEntry in the server
2418 to indicate if the server entry is disabled. Affected file
2419 silcd/idlist.h, silcd/command[_reply].c.

2422 started. Affected file silcd/silcd.c.
2424 * Added silc_server_packet_send_clients to send a packet to
2425 the provided table of client entries. Affected file
2426 silcd/packet_send.[ch].
2428 * Fixed a crash in client resolving in client_prvmsg.c in
2429 client library. Affected file lib/silcclient/client_prvmsg.c.
2431 * Do not actually remove the client directly from ID cache
2432 during SERVER_SIGNOFF, but invalidate it. This way we
2433 preserve the WHOWAS info for the client. Affected file
2434 silcd/server_util.c.
2436 * Fixed SERVER_SIGNOFF notify handling in the server. The
2437 server is now able to process incoming SERVER_SIGNOFF notify
2438 for a server that it doesn't even know about. It will remove
2439 the clients provided in the notify. Affected file
2440 silcd/packet_receive.c.
2442 * Check for partial packet in data queue after every packet that
2443 was found from the queue. Return and wait for more data if
2444 there is partial data in queue. Affected file is
2445 lib/silccore/silcpacket.c.
2447 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Added SilcClietFileError enum to indicate error in
2450 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2451 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2452 Affected files lib/silcclient/silcapi.h and
2453 lib/silcclient/client_ftp.c.
2455 * Check that newsize in silc_buffer_realloc is larger than
2456 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2458 * Added better monitor of file transfers. It now monitors
2459 key agreement protocol during the file transfer too. Added
2460 error reporting too. Affected files
2461 irssi/src/silc/core/silc-servers.c,
2462 irssi/src/fe-common/silc/module-formats.[ch].
2464 * Wrote a help file for FILE command.
2466 * Added silc_rng_global_get_byte_fast to get not-so-secure
2467 random data as fast as possible. Random data is read from
2468 /dev/urandom if available and from the SILC RNG if not
2469 available. It is used in padding generation. Affected file
2470 lib/silccrypt/silcrng.[ch].
2472 * All packets in client library are now processed synchronously.
2473 Optimized packet processing a lot. Affected file
2474 lib/silcclient/client.c.
2476 * All server connection packets are processing synchronously
2477 now in server, to optimize packet processing. Affected file
2480 * Include files are installed now only in Toolkit distribution
2481 if make install is given. Affected files: all Makefile.am's.
2483 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2485 * Assure that silc_client_notify_by_server_resolve does not
2486 resolve the client information multiple times. If it cannot
2487 be found by the first it cannot be found at all. Affected
2488 file lib/silcclient/client_notify.c.
2490 * Fixed WHOWAS command reply calling. Affected file
2491 lib/silcclient/command_reply.c.
2493 * Removed all references to silc_idlist_get_client from the
2494 Irssi SILC client since that call is internal call used by
2495 the library. The Irssi SILC client will use now client
2496 retrieval functions found in silcapi.h.
2498 * Fixed a bug in resolving nickname info before sending
2499 private message. It used freed memory. Affected file
2500 irssi/src/silc/core/silc-servers.c.
2502 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Assure my_channels statistics cannot go negative in server.
2505 Affected files silcd/server.c, silcd/server_util.c.
2507 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2517 lib/sftp/sftp_fs_memory.c.
2519 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2521 * Added silc_net_localip to return local host's IP address.
2522 Affected file lib/silcutil/silcnet.[ch].
2524 * If key exchange or rekey protocol is active for a connection
2525 parse all packets syncronously since there might be packets
2526 in packet queue that we are not able to process without first
2527 processing packets before them. Affected file silcd/server,
2528 lib/silcclient/client.c.
2530 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2531 whether library should continue processing the packet.
2532 Affected file lib/silccore/silcpacket.h.
2534 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2535 SilcSFTPMonitorData to SFTP server to monitor various

2544 transmission. Affected file lib/silcclient/client_ftp.c,
2545 lib/silccilent/client.[ch].
2547 * Added new local command FILE to the Irssi SILC Client.
2548 It is used to perform the file transfer. It has subcommands
2549 SEND, RECEIVE, SHOW and CLOSE. Affected files
2550 irssi/src/silc/core/client_ops.c,
2551 irssi/src/silc/core/silc-server.[ch].

2560 * Renamed silc_file_read and silc_file_write to functions
2561 silc_file_readfile and silc_file_writefile. Added function
2562 silc_file_open and silc_file_close. Affected files
2563 lib/silcutil/silcutil.[ch].
2565 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Resolve the client info when received private message or
2568 channel message for a client which nickname we don't know.
2569 Affected files lib/silcclient/client_prvmsg.c and
2570 lib/silcclient/client_channel.c.
2572 * Do not crash in /KEY if client is not connected. Affected

2578 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2579 is incomplete and is being resolved, it won't be resolved
2582 Make sure also that USERS command reply does not resolve
2583 twice information. Affected file is
2584 lib/silcclient/command_reply.c.
2586 Make sure that silc_client_get_clients_by_list does not
2587 resolve twice same information.
2589 * Check for valid client->id in the silc_server_free_client_data.
2590 Affected file silcd/server.c.
2592 * Fixed /GETKEY nick@server not to crash if the server entry
2593 is not found. Affected file lib/silcclient/command.c.
2595 * Fixed the silc_server_check_cmode_rights to check the
2596 requested modes correctly. Affected file silcd/command.c.
2598 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Better checks for non-printable chars in nick added.
2601 Affected file silcd/command.c.
2603 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Call the silc_server_udpate_servers_by_server in the
2606 primary router that comes back online in the backup resuming
2607 protocol. Otherwise it routes packets wrong. Affected file
2608 silcd/server_util.[ch], silcd/server_backup.c.
2610 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2612 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2613 lib/silcutil/silcbuffmt.[ch].
2615 * Redefined the SILC packet header to include the padding
2616 length. Affected file lib/silccore/silcpacket.[ch].
2618 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2619 length for maximum padding up to 128 bytes). Affected
2620 file lib/silccore/silcpacket.h.
2622 * Removed all backwards support for old 0.5.x MAC thingies.
2623 The SILC packet header change makes it impossible to be
2624 backwards compatible.
2626 * Send the ENDING packet with timeout in the backup resuming
2627 protocol. This is to assure that all routers has connected
2628 to the primary router. Affected file silcd/server_backup.c.
2630 * Changed the RNG to take the first IV from random data. It
2631 used to take it from zero actually. Changed the RNG also
2632 to use /dev/urandom during session. /dev/random is used
2633 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2635 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2637 * Changed the SILC packet header to have the first two bytes
2638 (the packet length) encrypted. Affected files aroung the
2639 code tree, lib/silccore/silcpacket.[ch]. Removed the
2640 SilcPacketCheckDecrypt callback. It is not needed anymore
2641 since the silc_packet_receive_process will determine now
2642 whether the packet is normal or special.
2644 * Implemented the unidirectional MAC keys. Affected files
2645 lib/silcske/silcske.c, silcd/protocol.c and
2646 lib/silcclient/protocol.c.
2648 * Implemented the packet sequence number to the MAC computation.
2649 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2650 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2651 lib/silcclient/protocol.c.
2653 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2655 * Allow backup router to announce servers. All servers
2656 announced by backup router are added to the global list
2657 automatically. Update hte server's socket to our primary
2658 router also when backup router announces a server.
2659 Affected file silcd/packet_receive.c.
2661 * Do not update the client->router in the function
2662 silc_server_udpate_clients_by_server if the client is on
2663 global list. We might fail to find any specific server
2664 for locally connected clients and local cell clients. They
2665 should still use the `from' and not `to' as client->router.
2666 This fixes backup router resuming protocol. Affected file
2667 silcd/server_util.c.
2669 * Decrease channel statistics count only if the channel
2670 deletion worked. Affected files are silcd/server.c and
2671 silcd/server_util.c.
2673 * Added silc_server_update_servers_by_server to update origin
2674 of all server entries. Used during backup router protocol.
2675 Affected files silcd/server_util.[ch], silcd/server.c. and
2676 silcd/backup_router.c.
2678 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2679 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2680 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2681 lib/silccrypt/silchmac.c.
2683 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2685 * Assure that router cannot reroute the same channel message
2686 to the sender. Affected file silcd/packet_receive.c.
2688 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Made better checks that the channel message is not sent
2691 to the router it came from. Affected file is
2692 silcd/packet_send.c. Fixed memory leak too.
2694 * Announce informations for incoming router connection, but
2695 only after checking if it is replaced by backup router.
2696 Affected file silcd/packet_receive.c.
2698 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Fixed the backup resuming protocol to work in multiple
2701 router environment. Affected file silcd/server_backup.c.
2703 * Route packet only to one router in the function
2704 silc_server_packet_send_to_channel. Affected file is
2705 silcd/packet_send.c.
2707 * Fixed silc_server_send_notify_dest to set the broadcast
2708 flag. Fixed the silc_server_send_notify_topic to actually
2709 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2710 Affected file silcd/packet_send.c.
2712 * Changed the SFTP Filesystem interface. Changed the
2713 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2714 the filesystem operation function. The SilcSFTPFilesystem
2715 is now a context that is allocated by all filesystem allocation
2716 functions and it already includes the operations structure
2717 and filesystem specific context. It is given as argument
2718 now to the silc_sftp_server_start. This made the interface
2719 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2720 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2722 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2724 * Changed the backup router adding and getting interfaces
2725 in the server. The router that will be replaced by the
2726 specified backup router is now sent as argument. Affected
2727 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2730 * Added silc_net_addr2bin_ne to return the binary form of
2731 the IP address in network byte order. Affected files
2732 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2734 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2736 * Check for existing server ID in silc_server_new_server
2737 and in silc_server_connect_to_router_final and remove the
2738 old entry if it exists. Affected file silcd/packet_receive.c,
2741 * Send the channel message always to only one router, either
2742 in upstream or downstream. Affected file is
2743 silcd/packet_send.c.
2745 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2747 * Wrote the definition of the backup resuming protocol to the
2748 protocol specification.
2750 * Removed one redundant channel key generation from normal
2751 server during joining procedure. Removed one redundant
2752 channel key sending from server to router during joining
2753 procedure. Affected file silcd/command.c.
2755 * Made minor bugfixes to the backup router resuming protocol.
2756 Affected file silcd/server_backup.c, server.c.
2758 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2760 * Added --disable-asm configuration option. Affected files
2761 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2764 * Implemented the backup resuming protocol that is used to
2765 resume the primary router position in the cell after the
2766 primary router comes back online. Affected files
2767 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2768 and silcd/server_util.[ch].
2770 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2772 * Sleep two (2) seconds after sending QUIT command to server.
2773 Affected file lib/silcclient/command.c.
2775 * Assure that if outgoing data buffer is pending do not force
2776 send any data. Affected file silcd/packet_send.c.
2778 * Assure that if outgoing data buffer is pending do not force
2779 send any data. Affected file lib/silcclient/client.c.
2781 * Implemented the backup router support when the primary router
2782 goes down. The servers and routers can now use the backup
2783 router as new primary router without loosing connectivity.
2785 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2788 in the server to indicate disabled entry. All data read
2789 from the connection will be ignored and no data is sent
2790 for entry that is disabled. Affected files are
2791 silcd/idlist.h, silcd/server.c.
2793 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Created SFTP client and server test programs in the
2796 lib/silcsftp/tests directory.
2798 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * Implemented memory filesystem (virtual filesystem) for
2801 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2804 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2806 * Implemented the SFTP (SSH File Transfer Protocol) to the
2807 lib/silcsftp. It includes SFTP client and SFTP server
2810 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2812 * Moved lib/silccore/silcprotocol.[ch] to the
2813 lib/silcutil library.
2815 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2816 take variable argument list pointer as argument. Affected
2817 file lib/silcutil/silcbuffmt.[ch].
2819 * Added silc_buffer_set function that is used to set data
2820 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2821 Affected file lib/silcutil/silcbuffer.h.
2823 * Changed various routines in the core library to use the new
2824 silc_buffer_set instead of allocating new buffer only for
2827 * Added 64-bit value formatting and unformatting support to the
2828 silc_buffer_[un]format routines. Affected file is
2829 lib/silcutil/silcbuffmt.[ch].
2831 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2832 to includes/bitmove.h.
2834 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2836 * Fixed channel user mode saving in client library. Affected
2837 file lib/silcclient/command[_reply].c.
2839 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * Defined the file transfer to the SILC Protocol. Added
2842 new packet type SILC_PACKET_FTP and defined File Transfer
2843 Payload. The mandatory file transfer protocol is SFTP
2844 (SSH File Transfer Protocol). Affected file in addition
2845 of the internet draft is lib/silccore/silcpacket.h.
2847 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2848 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2849 is used as part of backup router protocol when the primary
2850 router of the cell is back online and wishes to resume
2851 the position as primary router.
2853 * Redefined the MAC generation keys in the protocol. The
2854 same key is not used anymore in both direction. Both
2855 direction will now use different keys for sending and
2856 receiving. This fixes a potential security flaw. This
2857 change causes incompatibilities in the protocol.
2859 * Redefined also the MAC computation from the packet.
2860 An packet sequence number is now added to the MAC
2861 computation. This prevents possible replay attacks against
2862 the protocol. This change too causes incompatibilities
2865 Added `sequence' field to the SilcPacketContext to hold
2866 the current sequence number for the packet.
2868 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Added `created' field to the SilcIDListData in the file
2871 silcd/idlist.h to indicate the time when the entry was
2874 * Added `created' field to the SilcChannelEntry too. Affected
2875 file silcd/idlist.h.
2877 * Added `creation_time' aguments to all the announcement functions
2878 in the server. If it is provided then only the entries that
2879 was created after the provided time frame are actually
2880 announced. Affected file silcd/server.[ch].
2882 * The protocol says that the Channel ID's IP address must be
2883 based on the router's IP address. Added check for this in
2884 the silc_server_new_channel when processing incoming New Channel
2885 Payload. Affected file silcd/packet_receive.c.
2887 * Print out the correct version with --version in SILC client.
2888 Affected file irssi/src/silc/core/silc-core.c.
2890 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Fixed WHOWAS command to check for completnes of the client
2893 entry always, not just when the command is coming from client.
2894 Affected file silcd/command.c.
2896 * Added new function silc_server_packet_queue_purge to purge the
2897 outgoing data queue to the network. After the function returns
2898 it is guaranteed that the outgoing packet queue is empty.
2899 Affected file silcd/packet_send.[ch].
2901 * Purge the outgoing packet queue in the rekey protocol's final
2902 callback to assure that all rekey packets go to the network
2903 before quitting the protocol. Affected file silcd/server.c.
2905 * Added silc_client_packet_queue_parse as similar function as
2906 in server to the client library. The affected file is
2907 lib/silcclient/client.c.
2909 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Splitted silcd/server.c and created silcd/server_util.[ch]
2912 for utility functions.
2914 * Added new socket flag SILC_SF_DISABLED to indicate that the
2915 connection is open but nothing can be sent to or received from
2916 the connection. Affected file lib/silcutil/silsockconn.[ch].
2917 The checking for disabled socket is checked in the low level
2918 silc_socket_write and silc_socket_read functions.
2920 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * Allow only nicknames and channel names that fits into the
2923 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2925 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * When processing JOIN command reply in server check that if
2928 the channel exists in our global list we'll move it the local
2929 list. Affected file silcd/command_reply.c.
2931 * Fixed the check whether client is joined on the channel already
2932 in JOIN command. Affected file lib/silcclient/command.c.
2934 * Fixed the JOIN command reply to check whether the channel
2935 already exists. Affected file lib/silcclient/command_reply.c.
2937 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * Added silc_ske_status_string to map the SKE error numbers
2940 to readable strings. The affected files are
2941 lib/silcske/silcske[_status].[ch].
2943 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Do not show the private channels on the WHOIS channel list
2946 as it is not allowed by the protocol. The affected file is
2949 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2951 * Assure that the packet length digged from the actual packet
2952 is something sensible in the silc_packet_decrypt_rest_special
2953 in lib/silccrypt/silcpacket.c.
2955 * Free and NULL the allocated pointer in silc_hmac_alloc if
2956 the HMAC allocation fails. The affected file is
2957 lib/silccrypt/silchmac.c.
2959 * Print the selected security properties to the log files in
2960 the server. Affected file silcd/protocol.c.
2962 * Add SKE's reference counter even if calling the completion
2963 callback manually. Otherwise it goes negative, although it
2964 does not cause any problems. The affected file is
2965 lib/silcske/silcske.c.
2967 * Remove the client entry with short timeout after giving the
2968 KILL command. Affected file lib/silcclient/command.c.
2970 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2971 case all found clients are already disconnected (WHOWAS would
2972 found them) in the server. Affected file silcd/command.c.
2974 * Update the last_receive (time of last data received) to be
2975 updated only when received private or channel message so that
2976 the idle time showed in WHOIS makes more sense.
2978 * Added boolean field `valid' in to the SilcClientEntry in the
2979 client library to indicate whether the entry is valid or not.
2980 This fixes the nickname change bug on channel when changing
2981 the nickname to be same than the old (like nick to Nick) the
2982 nickname formatter doesn't set the new nick anymore to Nick@host.
2983 Affected file lib/silcclient/idlist.[ch].
2985 * Now actually fixed the nickname changing on disconnection.
2986 Added new function silc_change_nick to the Irssi SILC Client.
2987 Affected file irssi/src/silc/core/client_ops.c,
2988 irssi/src/silc/core/silc-nicklist.[ch].
2990 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2992 * Check that the public key exists in the GETKEY command before
2993 trying to encode it. Affected file silcd/command.c.
2995 * Print some notifications on received public keys with GETKEY
2996 command in the Irssi SILC Client. Affected files are
2997 irssi/src/fe-common/silc/module-formats.[ch],
2998 irssi/src/silc/core/client_ops.c.
3000 * Use IDENTIFY command to resolve the server information in the
3001 GETKEY command instead of INFO command. Affected file
3002 lib/silcclient/command.c.
3004 * All command reply functions in the client library now calls
3005 the pending command reply callbacks even if an error has
3006 occurred. The server has done this a long time and now it was
3007 time to move the client library to this as well. Now all
3008 errors can be delivered back to the pending command reply
3009 callbacks if necessary. Affected files are
3010 lib/silcclient/command[_reply].[ch].
3012 * Change the nickname on disconnection back to the username
3013 because in reconnect the server will enforce it to it anyway.
3014 Affected file irssi/src/silc/core/silc-servers.c.
3016 * Fixed a config file parsing bug in the Irssi SILC client.
3017 Affected file irssi/src/silc/core/clientconfig.c.
3019 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * When printing the channel mode on JOIN, verify that the
3022 channel key and channel's HMAC are valid. Affected file
3023 irssi/src/silc/core/client_ops.c.
3025 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3028 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3029 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3031 * Removed channel key rekey task deleting from the function
3032 silc_server_save_channel_key. Affected file silcd/server.c.
3033 Added explicit timeout task context instead that is used to
3034 delete the task if we are registering a new task before the
3035 new task has elapsed.
3037 * When channel key rekey occurs the client library now saves
3038 the old channel key for a short period of time (10 seconds) and
3039 is able to use it in case some is still sending channel
3040 messages encrypted with the old key after the rekey. Affected
3041 file lib/silcclient/[idlist.h|client_channel.c].
3043 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3045 * Added check to the silc_server_new_id_real to not accept
3046 new ID if it is the sender's own ID. Affected file is
3047 silcd/packet_receive.c.
3049 * Assure that we do not announce ourself or the one we've
3050 sending our announcements when we're router and are announcing
3051 servers to our primary router. Affected file silcd/server.c.
3053 * Fixed silc_server_command_identify_check_client to assemble
3054 correct WHOIS packet. It send corrupted WHOIS packet and
3055 caused problem with router to router connections. Affected
3056 file silcd/command.c.
3058 Fixed also silc_server_command_whois_check the same way
3059 as for the IDENTIFY command.
3061 * Added new SilcIDListStatus to the server in the SilcIDListData
3062 structure. The status now includes the current status of
3063 the entry (like registered, resolved etc.). Affected file
3064 silcd/idlist.[ch]. Defined a bunch of different status types
3065 as well. This replaced the old boolean registered field as well.
3067 Added resolve_cmd_ident field to the SilcClientEntry structure
3068 too so that if the entry is for example being resolved so
3069 another command may attach to the same pending command reply
3070 without requiring to resolve the same entry again. This concept
3071 should optimize the WHOIS and the IDENTIFY resolving under
3072 heavy load by taking away unnecessary resolving for entries
3073 that are being resolved already.
3075 Added support for adding multiple pending commands for one
3076 command idenfier. Affected file silcd/command[_reply].[ch].
3078 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3079 before deleting the data. Otherwise the hash table will have
3080 freed data in comparison functions. Affected file is
3081 silcd/command_reply.c.
3083 * Fixed silc_idlist_replace_client_id to add the new entry to
3084 the cache with NULL nickname. Otherwise there will be invalid
3085 memory as the nickname after the nickname is freed. Affected
3086 file silcd/packet_receive.c.
3088 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3089 saved into wrong slots because the previous number of entries
3090 was not taken into account. Affected file silcd/idlist.c.
3091 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3093 * If we are router and we receive JOIN notify to a channel that
3094 does not have any users then notified client is marked as the
3095 channel founder, as it is it. The affected file is
3096 silcd/packet_receive.c
3098 * Added to the extended hash table API's table_del_*ext functions
3099 the destructor as argument too, so that the caller can decide
3100 which destructor to use or whether to use destructor at all.
3101 Affected file lib/silcutil/silchashtable.[ch].
3103 * Fixed ID Cache purging. It actually deleted the entries from
3104 the hash table after the data was freed. The hash table ended
3105 up comparing freed memory. The affected file is
3106 lib/silccore/silcidcache.c.
3108 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3110 * Fixed Irssi SILC client's KILL command's HELP syntax.
3112 * The USERS command now resolves the detailed user information
3113 if the userinfo field is missing. Affected file is
3114 lib/silcclient/command_reply.c.
3116 * Do not print error in silc_file_read if the read file does
3117 not exist. Just silently return NULL. Affected file is
3118 lib/silcutil/silcutil.c.
3120 * Fixed the silc_log_output to not wine about NULL filename
3121 and to not create some bogus " " filename. Affected file is
3122 lib/silcutil/silclog.c.
3124 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3126 * Fixed various printing bugs on the user interface in the
3127 Irssi SILC Client. Minor changes that were forgotten from
3130 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3132 * Fixed the configure.in.pre and the compilation and distribution
3133 environment to support the new autoconf 2.52. That version is
3134 now required to compile the CVS trunk.
3136 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3138 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3139 to generally parse user@fqdn format strings. Affected file
3140 lib/silcutil/silcutil.c.
3142 * Added nickname_format and nickname_force_format fields to the
3143 SilcClientParams structure. The first one defines the format
3144 for the nicknames that the library will enforce if the receives
3145 multiple same nicknames. The second one is boolean value and
3146 can be used to force the library to always enforce the format
3147 to the nicknames regardles whether there are multiple nicknames
3148 or not. This configurable formatting was employed to flexibly
3149 support accessing multiple nicknames from the user interface.
3150 The userinterface can now set the nicknames to what ever format
3151 they prefer. Affected file lib/silcclient/silcapi.h.
3153 Added function silc_client_nickname_format to the file
3154 lib/silcclient/idlist.c. It performs the nickname formatting.
3156 Added new field `hostname´ to the SilcClientEntry context.
3157 It holds the hostname of the client. Affected file is
3158 lib/silcclient/idlist.h.
3160 * Irssi SILC Client sets the nicknames in nick@hostn format.
3161 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3162 irssi/src/silc/core/silc-core.c.
3164 The WHOIS printing now also shows both the real nickname and
3165 the formatted nickname so that user knows how to access the
3166 user if there are multiple same nicknames cached. Affected
3167 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3168 printing formatting too to take the hostname now as a separate
3169 argument. The Affected file is
3170 irssi/src/fe-common/silc/modules-formats.[ch].
3172 * Changed the silc_client_get_clients_local to accept the formatted
3173 nickname as argument. It accepts the real nickname too but the
3174 formatted nickname can be used to find the true entry from
3175 multiple entries. Affected file lib/silcclient/silcapi.h and
3176 lib/silcclient/idlist.c.
3178 * Added nickname_format_parse field to the SilcClientParams.
3179 It is a callback function provided by the application to parse
3180 the nickname out of the formatted nickname string. The library
3181 calls it to get the nickname from the formatted string. Since
3182 the application generally knows better the format of the nickname
3183 string it parses it instead of the library, even though library
3184 encodes the formatted string. If the callback function is not
3185 provided then the library will use the string as is. The
3186 affected file is lib/silcclient/silcapi.h.
3188 * All the nickname strings passed to the client library in
3189 commands are now expected to be formatted nickname strings.
3190 If the command does not support the formatted nickname string
3191 it will assume that the sent string is the actual nickname.
3192 Affected file lib/silcclient/command.c.
3194 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3196 * Added public key authentication support to OPER and SILCOPER
3197 commands in the client library. Affected file is
3198 lib/silcclient/command.c.
3200 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3202 * Changed the get_auth_methdod client operation to be asynchronous.
3203 It can be async if the application resolves the authentication
3204 method from the server during the negotiation. Added new
3205 SilcGetAuthMeth completion callback that the application will
3206 call after resolving the authentication method.
3208 Added function silc_client_request_authentication_method that
3209 the application can use to resolve the authentication method
3210 from the server. Added also SilcConnectionAuthRequest callback
3211 that the library will call after the server has replied. The
3212 application can call this function if it does not know the
3213 current authentication method.
3215 Affected files are lib/silcclient/client.c and
3216 lib/silcclient/silcapi.h.
3218 * The Irssi SILC client now automatically resolves the authentication
3219 method incase any configuration information is not present (and
3220 currently there never is). The affected file is
3221 irssi/src/silc/core/client_ops.c.
3223 * Fixed public key authentication from the client library.
3224 Affected file lib/silcclient/protocol.c. Changed also the
3225 protocol specification about the public key authentication in
3226 the connection authentication protocol. The actual data to be
3227 signed is now computed with a hash function before signing.
3229 * Fixed the public key authentication from the server as well.
3230 Affected file silcd/protocol.c.
3232 * Removed the mlock()'s from the memory allocation routines.
3233 Affected file lib/silcutil/silcmemory.c. The ./configure does
3234 not check anymore for the mlock(). Affected file is
3237 * Fixed USERS command in server to allow the execution of the
3238 command for private and secret channels if the client sending
3239 the command is on the channel. Affected file silcd/command.c.
3241 * Fixed silc_client_get_clients_local to return the clients
3242 count correctly. It could return wrong value. Affected file
3243 lib/silcclient/idlist.c.
3245 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3247 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3248 types. The assembler optimizations seemed not to like 64-bit
3249 data types. The assmebler optimizations thus are now enabled
3250 also for BSD systems as opposed to only enable them for Linux.
3252 * Do not check for threads at all on BSD systems. Affected
3253 file configure.in.pre.
3255 * Removed -n and -h options from the Irssi SILC Client since
3256 they are not used in silc.
3258 * Fixed the prime generation to assure that the first digit
3259 of the generated random number is not zero since our conversion
3260 routines does not like number strings that starts with zero
3261 digit. If zero digit is seen the random number is regenerated.
3262 This caused some corrupted RSA keys when the zero first digit
3263 was met. Affected file lib/silcmath/silcprimegen.c.
3265 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3267 * Fixed WIN32 configuration in the ./configure script.
3268 Fixed to include xti.h on environments that has it.
3269 Patches by Carsten Ilchmann and andrew.
3271 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3273 * Changed the silc_id_create_client_id to be collision
3274 resistant. It is now assured that there cannot be created
3275 two same client ID's. I suspect that some weird bugs in
3276 the server were actually caused by duplicate Client IDs.
3277 Affected file silcd/serverid.[ch]. A router receiving
3278 new ID now also assures and informs the sending server
3279 if the ID caused collision.
3281 * Changed the silc_id_create_channel_id to also assure that
3282 there are no collisions.
3284 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3286 * Statement about ignoring the Mutual Authentication flag when
3287 performing rekey with PFS was a bit misleading. It is ignored
3288 if it was set in the initial negotiation, it cannot be even
3289 set in the rekey. Fixed in the ke-auth draft. Started the
3290 new versions of the protocol drafts in the doc/.
3292 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3294 * Fixed a bug in silc_client_command_identify_save when saving
3295 new channel information. The channel name was no duplicated
3296 and caused crash on exit. Affected file is
3297 lib/silcclient/command_reply.c.
3299 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3301 * Fixed the getkey command handling in the server. Send just
3302 empty OK reply to the sender if the key could not be fetched
3303 (but everything else was ok, like the key just was not available).
3304 Changed the public key parameter to optional in the protocol
3305 specs so that empty OK reply can be sent. Affected file
3308 Added a message to Irssi SILC client to tell to user if the
3309 server did not return a public key.
3311 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3313 * Fixed a channel key regeneration bug. It registered new
3314 timeout tasks exponentially until all system resources were
3315 used. Affected file silcd/server.c.
3317 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3319 * Added the SILC Document generator to the scripts/silcdoc.
3320 It can be used to generate the Toolkit Reference Manual out
3321 of the source tree. Internally it will also use the RoboDoc
3322 generator now imported in util/robodoc.
3324 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3326 * Added couple of return's in rekey protocol if error orccurred
3327 during the protocol. The execution must be terminated.
3328 Affected file silcd/protocol.c. Also, terminate the protocol
3329 always with timeout.
3331 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3333 * The client's Client ID was created initally from the wrong
3334 nickname (it could have been in format nick@host) in the
3335 silc_server_new_client. Affected file silcd/packet_receive.c
3337 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3339 * Added some SILC_LOG_ERROR's to various error conditions
3340 if client could not be added to ID cache. Affected files
3341 silcd/packet_receive.c and silcd/server.c.
3343 * When client's sock->user_data is freed, NULL also the
3344 client->router and client->connection pointers. Added check
3345 for these pointers being NULL to various places around the
3346 code. Affected file silcd/server.c.
3348 * Added client->data.registered == TRUE checks to various
3349 places around the code to assure that unregistered client's
3350 are not handled when it is not allowed. Affected file
3353 * Added `bool registered' fields to all
3354 silc_idlist_[server|client]_get_* routines to indicate whether
3355 the fetched client needs to be registered or not. Affected
3356 file silcd/idlist.[ch].
3358 * Add your own entry as registered to the ID cache in the
3359 server. Affected file server.c.
3361 * Fixed a bug in silc_server_new_server. The SilcServer was
3362 set as the new server's context instead of SilcServerEntry.
3363 This naturally caused some weird bugs.
3365 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3367 * Do not delete the channel rekey task when adding it
3368 for in silc_server_create_channel_key.
3370 * Changed the silc_server_create_channel_key to return
3371 TRUE or FALSE to indicate the success of the channel key
3374 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3376 * Fixed MSVC++ project files and added missing files to
3377 Makefiles under win32/.
3379 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3381 * Do not add TCP_NODELAY flag if the operating system
3382 does not have it defined. Affected files are
3383 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3385 * Fixed buffer overflow from Irssi SILC Client. Affected
3386 file irssi/src/fe-common/core/themes.c.
3388 * Fixed double free in client library in the file
3389 lib/silcclient/client.c when disconnecting from server.
3391 * Applied double free patch from cras to Irssi SILC client.
3392 Affected files irssi/src/core/[modules/expandos].c
3394 * Fixed the disconnection handling to Irssi SILC Client.
3395 The application must call silc_client_close_connection
3396 in ops->connect client operation in case of failure of
3397 the connection. Affected file is
3398 irssi/src/silc/core/client_ops.c.
3400 * Do not set sock->protocol to NULL in the function
3401 silc_client_close_connection after executing the protocol's
3402 final callback since the sock might not be valid anymore.
3403 Affected file lib/silcclient/client.c.
3405 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * Do not enable SILC_THREADS if the linking with libpthread
3408 did not happen. Affected file configure.in.pre.
3410 * Added notion to protocol specification that server must
3411 verify the sent authentication payload with CMODE when
3412 setting the channel founder key. Implemented it to the
3413 server. Affected file silcd/command.c.
3415 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3417 * Added _EXTRA_DIST SILC distribution variable to the
3418 distributions file. It is used to conditionally add extra
3419 files or directories to the specific distribution. Affected
3420 files ./prepare, Makefile.am.pre and distributions.
3422 Removed the `_' from the start of the distribution names.
3425 * Added README.WIN32 for instructions to compile the Toolkit
3428 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * Fixed a double free in disconnection in the server. Affected
3431 file is silcd/server.c.
3433 * Fixed the lib/silcske/groups.c to work now also with GMP
3434 MP library. The string conversion did not work when using
3435 specific base and the base is indicated in the string as well.
3437 * Created win32/ directory which now includes MSVC++ specific
3438 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3439 It will appear only in the toolkit distribution
3441 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3443 * Changed the key material distribution function in case when
3444 the hash output is too short. The data is now concatenated
3445 a bit differently than it used to. Made the change to the
3446 SKE protocol specification.
3448 * Added better GMP detection to configure.in.pre. A patch
3451 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3453 * Fixed a minor bug in SKE that might cause some problem on
3454 some platforms. Affected file lib/silcske/silcske.c.
3456 * Added the cookie checking for initiator in the SKE. It checks
3457 that the responder returns the sent cookie unmodified. The
3458 affected file is lib/silcske/silcske.c. Added new SKE
3459 error type INVALID_COOKIE that can be sent during the
3460 negotiation. Fixed some memory leaks as well.
3462 * Added the "invalid cookie" error message to Irssi SILC client's
3465 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3467 * Added `task_max' field to the SilcClientParams to indicate
3468 the maximum tasks the scheduler can handle. If set to zero,
3469 default values are used. Affected file lib/silcclient/silcapi.h.
3471 * Fixed memory leaks in silc_client_close_connection. Affected
3472 file lib/silcclient/client.c.
3474 * Added silc_client_del_client_entry to client library to free
3475 all memory of given client entry. Affected file is
3476 lib/silcclient/idlist.[ch].
3478 * Added new functions silc_client_del_channel and
3479 silc_client_del_server to delete channel and server entries.
3480 Affected file lib/silcclient/[silcapi.h/idlist.c].
3482 * Removed silc_client_del_client_by_id from silcapi.h.
3484 * Fixed the INFO command to return the server's own info
3485 correctly when querying by Server ID. Affected file is
3488 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3490 * Removed the non-blocking settings in WIN32 code in the
3491 silc_sock_[read/write] and added SleepEx instead. Affected
3492 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3493 of input data is now checked with FIONREAD and ioctlsocket.
3495 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3497 * Call silc_schedule_task_del_by_context in the
3498 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3499 Affected file lib/silccore/silcprotocol.c.
3501 * Call silc_protocol_cancel for active protocols in the
3502 silc_server_close_connection if the funtion
3503 silc_server_free_sock_user_data has not been called.
3504 Affected file silcd/server.c.
3506 * Generic tasks cannot be deleted using the del_by_fd
3507 task deleting function since generic tasks does not match
3508 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3510 * Added a notion to SILCOPER help file that the SILCOPER works
3511 only on router server, not on normal server.
3513 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3515 * Added for WIN32 support for the new scheduler as well.
3516 Affected file lib/silcutil/win32/silcwin32schedule.c.
3518 * Fixed the SHA1 implementation to work on various platforms.
3520 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3522 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3523 API. It is part of the scheduler now. Everything else is
3524 as previously but some functions has changed their names.
3525 Checkout the lib/silcutil/silcschedule.h for the interface.
3526 Updated all applications to use the new interface. Affected
3527 files are lib/silcutil/silcschedule.[ch].
3529 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3531 * Found a bug in the SKE implementation. The HASH value,
3532 specified by the protocol, was not computed correctly. The
3533 public key of the responder was not added to the computation
3534 even though it is mandatory. Affected file lib/silcske/silcske.c.
3535 This unfortunately causes incompatibilities with older
3536 clients and servers.
3538 * Added WIN32 specific network init and uninit functions:
3539 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3540 the Winsock2. Affected file lib/silcutil/silcnet.h and
3541 lib/silcutil/win32/silcwin32net.c.
3543 * Set the socket always to nonblocking mode on WIN32 after
3544 reading data or writing data. Affected file is
3545 lib/silcutil/win32/silcwin32sockconn.c.
3547 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3549 * Fixed various compilation problems under WIN32. Affected
3550 files lib/silcutil/win32/silcwin32thread.c and
3551 lib/silcutil/win32/silcwin32schedule.c.
3553 * Removed all _internal.h #includes from public header
3554 files. Internal headers must never be included from
3557 Removed also the lib/silcske/payload_internal.h file.
3559 * All include files that may be needed (public and some others
3560 included by the public headers) by application developers are
3561 now copied to the ./includes directory. It does not copy any
3562 internal headers. Affected file Makefile.defines.pre and all
3563 Makefile.am's under lib/ and subdirs.
3565 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3567 * Do not change the ~/.silc directory's permissions automatically.
3568 Affected file irssi/src/silc/core/clientutil.c.
3570 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3572 * Do not cancel the protocol in silc_server_close_connection
3573 it might cause recursion. Now cancelled in the function
3574 silc_server_free_sock_user_data. Affected file silcd/server.c.
3576 * Fixed the silc_server_remove_clients_by_server to regenerate
3577 the channel keys correctly finally. Added also new function
3578 silc_server_remove_clients_channels to actually do it.
3579 Affected file silcd/server.c.
3581 * Fixed the silc_server_new_channel to not crash by giving
3582 wrong router to the new channel. Affected file is
3583 silcd/packet_receive.c.
3585 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3587 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3588 which is given as argument to the silc_client_alloc now.
3589 It can be used to configure the client and set various parameters
3590 that affect the function of the client.
3592 * The USERS command in server did not check whether the channel
3593 is private or secret. Affected file silcd/command.c.
3595 * Added new argument to the USERS command in protocol specification.
3596 The USERS command now can take the channel name as argument
3597 as well. Added support for this in client and server and
3598 updated the protocol specs.
3600 * Completed the GETKEY command in client. It can be now used
3601 to fetch also servers public key not only some clients.
3602 Affected files lib/silcclient/command[_reply].c.
3604 * Added silc_client_get_server to return server entry by the
3605 server name. Affected files lib/silcclient/silcapi.h and
3608 * Redefined the IDENTIFY command in protocol specification to be
3609 more generic. It now can be used to query information about
3610 any entity in the SILC Network, including clients, servers and
3611 channels. The query may be based either the entity's name
3612 or the ID. Added support for this in both client and server.
3614 Affected files silcd/command.c and lib/silcclient/command.c
3615 and command_reply.c.
3617 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3618 the _from_client and _from_server functions. Affected file
3621 * Added silc_client_get_channel_by_id_resolve to the file
3622 lib/silcclient/silcapi.h to resolve channel information by
3623 its ID. Added also silc_client_get_channel_by_id that
3624 does not resolve it from the server.
3626 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3628 * Added SilcServerEntry context into the client library
3629 to represent one server. The INFO command now allocates
3630 these to save the resolved server info. For now on the
3631 client library will also keep information about servers,
3632 connected and resolved with INFO.
3634 The INFO command now allocates the SilcServerEntry context
3635 and saves the server info there. The COMMAND_REPLY in
3636 the INFO now returns the parameters to application in
3637 same order as defined in the protocol specification.
3639 The entries are cached in the client->server_cache.
3641 * The INFO command is now issued after received the Client ID
3642 from the server. Affected file lib/silcclient/client.c.
3644 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3645 to the application as the mode changer might be server.
3646 It is guaranteed that NULL is not returned anymore to the
3647 application. Affected file lib/silcclient/client_notify.c.
3649 The ID Type is now also passed to the application so that
3650 it can check whether the returned entry is SilcClientEntry
3653 Added new function silc_client_get_server_by_id to return
3654 the server entry by ID. Affected files are the
3655 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3657 * Do not create the channel in the Irssi SILC Client when issuing
3658 the JOIN command but when received the sucessful JOIN command
3659 reply. Otherwise the channel might get created even though we
3660 could not join it. The Affected file is
3661 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3663 * Fixed a channel joining bug in router. The router must also
3664 check the channel modes, invite and ban lists etc. when serving
3665 the JOIN command sent by normal server. Affected file is
3666 silcd/command.c. The router now resolves the client's
3667 information from the server who sent the JOIN command if it
3668 does not know it, and processes the JOIN command only after
3671 * Changed the SilcCommandCb to take new argument; void *context2.
3672 Affected file lib/silccore/silccommand.h
3674 The second argument in the command callbacks in the server now
3675 includes the SilcServerCommandReplyContext if the command was
3676 called as pending command callback from the command reply.
3677 Otherwise it is NULL. When called as pending the status of the
3678 command reply will be checked and if it was erronous the
3679 error will be sent to the original sender of the command.
3680 This way the client always receives the error messages even
3681 though the server was actually the one who received the error
3682 when it resent the command to router, for example. Affected
3683 files silcd/command[_reply].[ch].
3685 * Fixed sending WHOWAS command's error message to client if
3686 the requested client could not be found. It was missing.
3689 * Changed the CMODE and CUMODE commands reply arguments in the
3690 protocol specification. The Channel ID is now sent in both
3691 of the commands to identify the channel. Implemented this
3692 new feature to the client and server. Affected files
3693 lib/silcclient/command_reply.c and silcd/command.c.
3695 * Made better checks for invite and ban lists in the JOIN
3696 command in server. Affected file silcd/command.c.
3698 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3700 * The server now performs the incoming host IP/DNS lookup
3701 using the silc_socket_host_lookup and thus does not block
3702 the server anymore. Affected file silcd/server.c.
3704 * Completed the multi-thread support for SILC Scheduler in
3705 the lib/silcutil/silcschedule.c.
3707 * Fixed the configure.in.pre to detect the pthread correctly
3710 * Fixed a deadlock in silc_task_queue_wakeup in the file
3711 lib/silcutil/silctask.c.
3713 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3715 * Added new function silc_schedule_wakeup that is used in
3716 multi-threaded environment to wakeup the main thread's
3717 schduler. It needs to be used when a thread adds a new task
3718 or removes a task from task queues. After waking up, the
3719 scheduler will detect the task queue changes. If threads
3720 support is not compiled in this function has no effect.
3721 Implemented the wakeup mechanism to both Unix and WIN32
3722 systems. Affected files are lib/silcutil/silcschedule.[ch],
3723 lib/silcutil/unix/silcunixschedule.c and the
3724 lib/silcutil/win32/silcwin32schedule.c.
3726 * Added new function silc_task_queue_wakeup to wakeup the
3727 scheduler by the specified task queue. Affected file
3728 lib/silcutil/silctask.[ch].
3730 * The silc_socket_host_lookup_start now wakes up the scheduler
3731 after adding the timeout task. Affected file is
3732 lib/silcutil/silcsockconn.c.
3734 * The silc_socket_host_lookup is synchronous now if the threads
3735 support is not compiled in. However, the callback is still
3736 called asyncronously through the scheduler, anyway. Affected
3737 file lib/silcutil/silcsockconn.c.
3739 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3741 * Added new function silc_socket_host_lookup to perform
3742 asynchronous IP and FQDN lookups for the socket connection.
3743 Affected files lib/silcutil/silcsockconn.[ch].
3745 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3747 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3748 that may or may not compile the mutex support in.
3750 Changed the silc_mutex_alloc interface. It allocates the
3751 mutex now to the sent pointer and returns TRUE or FALSE.
3753 Affected file lib/silcutil/silcmutex.h.
3755 * Wrote the SILC Task Queue interface to support multi-threads.
3756 Affected file lib/silcutil/silctask.[ch].
3758 * Wrote the SILC Scheduler to support multi-threads. Affected
3759 file lib/silcutil/silcschedule.c.
3761 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3763 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3764 in lib/silcutil/win32/.
3766 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3768 * Defined SILC Mutex API and SILC Thread API and implemented
3769 them for Unix. Affected files are
3770 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3771 lib/silcutil/unix/silcunixmutex.c and
3772 lib/silcutil/unix/silcunixthread.c.
3774 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3776 * Fixed the silc_server_remove_clients_by_server's channel
3777 key re-generation. The hash table handling was incorrect
3778 and would not work with many channels. Affected file is
3781 * Fixed some memory leaks around the server code.
3783 * Rewrote the silc_server_get_users_on_channel to support IPv6
3784 based Client ID's. Affected file silcd/server.c.
3786 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3787 specification. However, a separate document must be written
3788 to define the detailed signing procedure and the payload
3789 associated with the flag. Defined the flag to the
3790 lib/silccore/silcchannel.h as well.
3792 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3794 * Changed the dynamic tables to static size tables in the
3795 lib/silccrypt/silchmac.c.
3797 * Removed GCC dependencies from the code. A patch by cras.
3799 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3801 * Do not show the error "Error receiving packet bla bla"
3802 in server if it really was not an error (-2 means that reading
3803 is pending). Affected file silcd/server.c.
3805 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3807 * Fixed a possible crash in silc_server_remove_clients_by_server
3808 in silcd/server.c. Fixed there also some memory leaks.
3810 * Fixed the silc_idlist_replace_client_id. It could replace
3811 wrong key in the hash table. Affected file silcd/idlist.c.
3813 * Do not check whether there are global users on the channel
3814 if the channel->global_users is FALSE. Affected functions
3815 silc_server_remove_from_one_channel and
3816 silc_server_remove_from_channels in silcd/server.c. Also,
3817 do not check if the removed client is local as we can be
3818 sure that global client was not removed from the channel
3819 and checking for global users is not needed.
3821 * The silc_server_remove_clients_by_server now re-generates
3822 the channel keys correctly for those channels that had
3823 clients removed from them. Affected file silcd/server.c.
3825 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3827 * Found the reason of random crashes in the server. We weren't
3828 ignoring the SIGPIPE signal (which can be sent in write())
3829 and it crashed the server. Affected file silcd/silcd.c.
3831 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3833 * Assure that sock->user_data is not NULL in the function
3834 silc_server_packet_send in silcd/packet_send.c.
3836 * Disconnect the remote connection if it could not be added
3837 to any ID lists in the server. The affected file is
3840 * Check in silc_server_packet_send[_real/dest] that the
3841 socket is not disconnecting and ignore the data if it is.
3842 Affected file silcd/packet_send.c.
3844 * Define inline to __inline on native WIN32 compilation.
3845 Affected file includes/silcwin32.h.
3847 * Added some explicit type casts for inline code since MSVC
3848 require them. Affected files lib/silcutil/silcbuffer.h,
3849 lib/trq/silcdlist.h and lib/trq/silclist.h.
3851 * Print warning in log files from now on if the packet
3852 decryption fails. Affected file silcd/server.c.
3854 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3856 * Changed the `say' client operation's interface to accept
3857 new `type' argument to indicate the type of the message sent
3858 by the library. The application may filter the library's
3859 messages according the type. The affected file is the
3860 lib/silcclient/silcapi.h.
3862 * Added two new functions to lib/silcclient/silcapi.h:
3863 silc_client_del_client and silc_client_del_client_by_id.
3864 Affected file lib/silcclient/idlist.c.
3866 * Moved the clientincludes.h from includes/ to silc/ and
3867 serverincludes.h from includes/ to silcd/.
3869 * The modes for the CMODE and CUMODE are now passed as
3870 uint32 for application with COMMAND_REPLY. The affected
3871 file is lib/silcclient/command_reply.c.
3873 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3875 * /WHOIS without arguments shows client's own information.
3876 Affected file lib/silcclient/command.c.
3878 * Changed PING to not accept any arguments. The specs
3879 says that client can ping only the connected server so
3880 requiring an argument is not needed. Affected file is
3881 lib/silcclient/command.c.
3883 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3885 * Fixed a fatal bug in private message sending and reception
3886 encryption and decryption when using private message keys.
3887 The implementation was incorrect and did not follow the
3888 specification. It causd that some of the message were
3889 lost since it did not use the sending and receiving keys
3890 as the protocol suggests. This has been fixed and will cause
3891 incompatibilities with older clients when sending private
3892 message encrypted with private message keys. Affected files
3893 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3894 and various other in Irssi SILC Client.
3896 Added `responder' boolean argument to the functions
3897 silc_client_add_private_message_key[_ske] to indicate when
3898 the key is added as responder or initiator of the key
3901 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3903 * Removed the silc_ske_check_version function and created
3904 a SilcSKECheckVersion callback. Added also a function
3905 silc_ske_set_callbacks that is now used to set all SKE
3906 callbacks. The callback functions are not given to
3907 the SKE functions anymore, but this function is used to
3910 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3912 * Added `silc_version' argument to the silc_client_alloc
3913 to define the version of the application for the library.
3914 The library will use the version string to compare it
3915 against the remote host's (usually a server) version
3916 string. Affected file lib/silcclient/silcapi.h
3918 * Added the KE protocol context to Key Agreement context
3919 in client library so that we can abort the SKE if it
3920 is in process when we get timeout. Affected file is
3921 lib/silcclient/client_keyagr.c.
3923 * Do not resolve the client ID forever if it returns in the
3924 first time that such client does not exist. This was done
3925 for example with private message. Affected file is
3926 lib/silcclient/client_prvmsg.c.
3928 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3930 * Do not add regex.h for WIN32. The affected file
3931 includes/silcincludes.h.
3933 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3934 not work yet 100%. It generates the DLL's automatically
3935 when compiling with --with-win32 under cygwin.
3937 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3939 * lib/contrib/regex.c is not compiled on WIN32.
3941 * Added silc_net_get_socket_opt function to the
3942 lib/silcutil/silcnet.h.
3944 * Added includes/silcwin32.h for WIN32 specific includes
3947 * Do not use ptime structure or any of the posix process
3948 functions on WIN32 in lib/silccrypt/silrng.c.
3950 * Added silc_gettimeofday to provide generic function
3951 for struct timeval on all platforms. Added the function
3952 to lib/silcutil/silcutil.h.
3954 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3956 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3957 library as they clearly belong there. As a plus side we
3958 can make the actual socket connection routines platform
3961 Added also new generic function silc_socket_read and
3962 silc_socket_write (that used to be silc_packet_[read/write].
3963 The implementation of these are platform specific.
3965 * Added WIN32 specific routines of silc_socket_[read/write]
3966 to lib/silcutil/win32/silcwin32sockconn.c.
3968 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3970 * Added preliminary support for native WIN32 compilation under
3971 cygwin (using the -mno-cygwin option for GCC) to the
3972 ./configure.in.pre. The --with-win32 now prepares the
3973 compilation for native WIN32.
3975 * Rewrote the SILC Scheduler interface in the file
3976 lib/silcutil/silcschedule.h. The scheduler is now context
3977 based and does not have anymore any global static scheduler.
3978 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3979 and created lib/silcutil/win32 directory for WIN32 based
3982 * Added Unix specific network routines to the
3983 lib/silcutil/unix/silcunixnet.c and the old
3984 lib/silcutil/silcnet.c includes now only generic routines.
3986 Added WIN32 specific network routines to the
3987 lib/silcutil/win32/silcwin32net.c.
3989 * Added Unix specific utility functions from the
3990 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3992 * Added WIN32 SILC Scheduler to the file
3993 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3996 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3998 * Do not handle JOIN notify in the server if the target client
3999 is not registered (idata->registered == FALSE). The affected
4000 file is silcd/packet_receive.c.
4002 * Update the nickrec->founder in event_cumode in the Irssi SILC
4003 client. Affected file irssi/src/silc/core/silc-channels.c.
4005 * Fixed the CUMODE_CHANGE notify handling in the server when
4006 server and router are announcing their clients on channels.
4007 Now the mode changes are saved and notified correctly. The
4008 affected file is /silcd/packet_receive.c.
4010 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4011 They really did not replace the cache entry in the ID Cache.
4012 Now they do that. Affected file silcd/idlist.c.
4014 * Fixed the KICK notify handling in the Irssi SILC client to
4015 update the channel records so that the kicked client does not
4016 appear to be on the channel. The affected file is
4017 irssi/src/silc/core/silc-channels.c.
4019 * Always update the conn->current_channel when executing command
4020 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4022 * Fixed the KILL notify handling in Irssi SILC client to remove
4023 the killed client on all channels.
4025 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Fixed the silc_parse_command_line to remove extra spaces
4028 from the start and end of the arguments. Affected file is
4029 lib/silcutil/silcutil.c.
4031 * Cancel and free any active protocol in the function
4032 silc_server_close_connection. Affected file silcd/server.c.
4034 * Cancel and free any active protocol in the function
4035 silc_client_close_connction. Affected file is
4036 lib/silcclient/client.c.
4038 * Do not execute the KILL command for clients that are in
4039 history (ie. they are not in the network). Affected file is
4042 * Fixed KILL notify handling, client does not crash anymore.
4043 Affected file irssi/src/silc/core/silc-channels.c.
4045 * Reduced the default packet buffer size from 2048 to 1024 in
4046 lib/silccore/silcpacket.c.
4048 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4049 counter to the SKE context that is incresed when the SKE library
4050 performs async operation outside the library. If the outside
4051 process frees the SKE context and FREED status will be set
4052 and the library will detect after the sync operation that the
4053 libary is freed. The affected files are
4054 lib/silcske/silcske[_status].[ch].
4056 * Resolve the client entry information in the function
4057 silc_client_channel_message to assure that NULL pointer is not
4058 passed as client entry to the application. */
4060 * Fixed the task timeout calculation to assure that there is
4061 never negative timeouts. The affected file is
4062 lib/silcutil/silcschedule.c.
4064 * Fixed the channel user mode notification sending in server.
4065 It was sent point-to-point to the router (or to server by router)
4066 but it needs to be destined to a channel. The routines now
4067 supports sending the channel user mode notifys to the channels
4068 when announcing clients and channels. Affected files are
4069 silcd/server.c and silcd/packet_receive.c.
4071 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4072 It did not actually replace the old channel entry in the cache.
4073 Affected file lib/silcclient/client_notify.c.
4075 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Fixed a possible crash in silc_packet_send_prepare. It now
4078 assures always that there is enough space in the buffer and
4079 at the tail area of the buffer (for MAC).
4081 Fixed the inbound buffer reallocation in silc_packet_read.
4082 It was old code and did not handle the reallocation correctly.
4085 The affected file is lib/silccore/silcpacket.c.
4087 * Fixed buffer overflow in silc_parse_nickname in the file
4088 lib/silcutil/silcutil.c.
4090 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * make install generates new server keys only if there is not
4095 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4097 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4098 Added check that if the NOREPLY is set then we will not send
4099 the away message. This avoids infinite loop of away messages
4100 if both clients are away. The affected file is
4101 lib/silcclient/client_prvmsg.c.
4103 * Fixed client crash if /NICK was given without arguments.
4104 Affected file lib/silcclient/command.c.
4106 * Server does not send the invite list in INVITE command back
4107 to the client if the list was not altered. Added this notion
4108 to the protocol spec as well. Affected file silcd/command.c.
4110 Fixed possible crash in INVITE command by checking the
4111 value of silc_server_get_client_route command.
4113 * Fixed the INVITE notify type handling. The arguments are now
4114 taken in correct order and client does not crash. The affected
4115 file is irssi/src/silc/core/silc-channels.c.
4117 Removed the "Inviting xxx to channel" message from the
4118 client library away and let the application handle it.
4119 Affected file lib/silcclient/command.c. Added that message
4120 to Irssi SILC client's message formats.
4122 * Fixed CMODE command crash in client. It now checks the
4123 amount of arguments correctly and does not crash. The affected
4124 file is lib/silcclient/command.c.
4126 * Do not create new channel automatically in silc_channels_join
4127 but check whether the channel by that name already exists.
4128 Affected file irssi/silc/core/silc-channels.c.
4130 * Do not send the SERVER_SIGNOFF to router if the disconnected
4131 entity was the router. Affected file silcd/server.c.
4133 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4134 SILC client as it was missing from there.
4136 Added the handling of the KICK notify to the Irssi SILC client
4137 as it was missing. Added "you have been kicked" message to
4138 Irssi SILC client's message modules formats.
4140 Added the handing of the KILL notify to the Irssi SILC client
4141 as it was missing. Added the kill message module formats
4144 The affected file is irssi/src/silc/core/silc-channels.c.
4146 * The router did not save the channel mode the server announced.
4147 Affected file silcd/packet_receive.c.
4149 * Fixed a possible crash in INFO command in server. If the
4150 server did not provide the server info it crashed. Affected
4151 file silcd/command.c.
4153 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Fixed the GETKEY command in the server to check also the
4156 global list. Otherwise the GETKEY would not work correctly
4157 in normal SILC server. Affected file silcd/command.c.
4159 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Fixed GETKEY crash, it crashed if the command did not succseed.
4163 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4166 is now real and not just an macro interface to GMP.
4168 Removed the entire GMP from the source tree and imported new
4169 NSS MPI library instead. Reason for removing GMP is that it is
4170 extremely large and compiles extremely slow. The NSS MPI
4171 is only a few files and compiles in less than 10 seconds.
4172 The speed is also about the same as GMP. The MPI is imported
4173 to lib/silcmath/mpi.
4175 If the system has GMP installed we will still use the GMP.
4176 If it is not then the NSS MPI will be compiled.
4178 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Merged a long nickname (127 characters long) crash bugfix from
4181 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4183 * Merged a freed memory reference bugfix from Irssi CVS tree.
4184 Affected file irssi/src/core/commands.c.
4186 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Added the server's public key sving and verification to the
4189 server when performing the SKE. This was missing and the
4190 remote server's (or router's) public key was accepted without
4191 checking whether we have it previously or trust it at all.
4192 Affected file silcd/protocol.c.
4194 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Check in the silc_server_timeout_remote if protocol is active
4197 and make sure that the protocol's final callback is called so
4198 that all memory if freed. Affected file silcd/server.c.
4200 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * silc_server_whois_send_reply crashed the server if the nickname
4203 was 127 characters long. Affected file silcd/command.c.
4205 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Added sanity check to the silc_server_new_client. If the hostname
4208 is provided inside username then check that the provided hostname
4209 really is the same as the resolved one. If the hostname was not
4210 resolved then check it from the public key. Affected file is
4211 silcd/packet_receive.c.
4213 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4214 if the server disconnected us and the connection is not valid
4215 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4217 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4218 the library to the lib/silcutil/silcutil.[ch].
4220 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Close log file after open. Affected file
4223 lib/silcutil/silclog.c.
4225 * Check whether sock == NULL in silc_client_send_packet and return
4226 if it is. Affected file lib/silcclient/silcclient.c.
4228 * Check rec->entry == NULL in the Irssi SILC Client before
4229 sending the channel message. Affecte file is
4230 irssi/src/silc/core/silc-servers.c.
4232 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Merged a splitted window bugfix from Irssi CVS tree. The
4235 affected file is irssi/src/fe-text/textbuffer-view.c.
4237 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4238 It did not print nickname.
4240 * Improved the distributions system a bit.
4242 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4245 irssi/src/fe-text/gui-window.c.
4247 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4248 to in-active server. The affected file is
4249 irssi/src/silc/core/client_ops.c.
4251 * Resolve the client in USERS command reply if the entry does
4252 not have username resolved. The affected file is
4253 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4254 command to WHOIS command to really resolve stuff. The USERS
4255 is not used any more in any critical section so WHOIS can
4256 be used even though it might be slower than IDENTIFY.
4258 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4261 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Changed the protocol API a bit more consistent in the
4264 lib/silccore/silcprotocol.[ch].
4266 * Changed the following headers to ROBODoc format:
4268 lib/silccore/silcpayload.h
4269 lib/silccore/silcprotocol.h
4270 lib/silccore/silcsockconn.h
4272 All core library headers are now formatted.
4274 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4276 * Fixed a bug in Irssi SILC client; do not show that you are
4277 server/router operator if you really are not. Affected file is
4278 irssi/src/silc/core/client_ops.c.
4280 * Renamed silc_command_free_payload to silc_command_payload_free.
4281 Affected file lib/silccore/silccommand.h
4283 * Added silcmath.h to include the prototoypes of various routines
4284 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4287 * Changed the following headers to ROBODoc format:
4289 lib/silccore/silcchannel.h
4290 lib/silccore/silccommand.h
4291 lib/silccore/silcid.h
4292 lib/silccore/silcidcache.h
4293 lib/silccore/silcmode.h
4294 lib/silccore/silcnotify.h
4295 lib/silccore/silcpacket.h
4296 lib/silcmath/silcmath.h
4298 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Added checking to the server code not to start the server if
4301 ciphers and stuff are not configured properly. Affected files
4302 silcd/serverconfig.[h] and silcd/server.c.
4304 * Changed the layout of the header files of the public interfaces
4305 in the SILC libraries. The new layout supports ROBODoc
4306 documentation tool (and some others) so that it is easy to create
4307 a library reference manual. All the other headers and source
4308 code must still follow the CodingStyle document. Also source
4309 code must not include these ROBODoc stuffs, only the headers.
4310 Furthermore, all public interface headers must now be named
4311 by using `silc' prefix, example: silcapi.h, silccipher.h.
4312 Some files were renamed due to this. All the other headers
4313 must not be used as public interfaces. I will update the
4314 CodingStyle document later. Changed following headers, so far:
4316 lib/silcclient/silcapi.h
4317 lib/silccore/silcauth.h
4318 lib/silccore/silcprivate.h
4319 lib/silccrypt/silcdh.h
4321 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Removed silc_client_packet_send_flush from the client library
4326 as it is not needed. Affected file lib/silcclient/client.[ch].
4328 * Added printing of message of unresolved authentication method
4329 to the Irssi SILC client. Added it to the module formats.
4330 Removed the same message from the client library.
4332 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Added new distribution feature, DISTLABEL. Every distribution
4335 can define own preprocessor label that can be used in the
4336 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4337 file distributions, acconfig.h.pre and prepare.
4339 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Added Makefile.defines_int to include the actual definitions
4342 for Makefile.defines.in. Tested the new distribution system,
4343 created distributions and tested installation.
4345 * Added AWAY message printing to the Irssi SILC client. Added
4346 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4348 * Added SCONNECT command to call the SILC's CONNECT command.
4349 Cannot use CONNECT directly since Irssi uses that internally.
4350 Affected file irssi/src/silc/core/silc-servers.c.
4352 Added ACTION local command. It is same as ME command but takes
4353 the channel as mandatory argument.
4355 Rewrote some of the Irssi's help files to suite for SILC
4358 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Added Makefile.defines[.in] that should for now on be included
4361 in all Makefile.am file in the source tree. That file includes
4362 all common compilation definitions for SILC source tree.
4364 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Minor changes to the ./prepare script to change the package
4367 name according the distribution name to the configure.in.
4369 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4371 * Created new distribution system. Added file `distributions'
4372 that defines all the distributions that can be created out of
4373 the SILC source tree. The ./prepare script now reads that
4374 file to determine how to prepare the distributions. The
4375 first argument to the ./prepare is the name of the distribution
4376 and second is the version of the distribution. If given
4377 without arguments it creates the default (toolkit) distribution
4378 with the default version (defined in ./prepare).
4380 All Makefile.am files that are subject to the distributions
4381 are now named as Makefile.am.pre. These are ./Makefile.am
4382 and lib/Makefile.am. Others may be changed later.
4384 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Added invite list, ban list, some key management and connection
4387 error message printing to module formats in the Irssi SILC client.
4389 * Added new silc_client_set_away_message to set the away message
4390 that is back to the person who sent private message. The
4391 affected file lib/silcclient/silcapi.h and the
4392 lib/silcclient/client_prvmsg.c.
4394 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Fixed the private message sending in the Irssi SILC client,
4397 added local command KEY to the Irssi SILC client.
4399 Added key management and key agreement message formats to the
4400 irssi/src/fe-common/silc/module-formats.[ch].
4402 Added USERS (alias WHO) printing, server/router operator
4403 indication and LIST command printing to the module formats.
4405 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Fixed channel joining notify handling, cumode notify handling
4408 from Irssi SILC client.
4410 * Added SILC specific module-formats to the Irssi SILC client so
4411 that SILC specific message hilighting, colors etc is possible.
4412 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4414 Added channel mode, channel user mode, actions, notices,
4415 whois and whowas printing to the the module-formats.c.
4417 * Fixed a bug in channel deletion in the server. The channel
4418 is not left to the cache even if the channel founder auth mode
4419 is set when there are no users anymore on the channel. Affected
4420 file silcd/server.c.
4422 * The silc_net_localhost now resolves the entire hostname including
4423 the domain name. Affected file lib/silcutil/silcnet.c.
4425 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Changed the ask_passphrase client operation to be ascynchronous.
4428 It has now a completion callback and a context that the
4429 application must call after it has got the passphrase from
4430 the user. Affected files lib/silcclient/silcapi.h,
4431 lib/silcclient/protocol.c, lib/silcclient/command.c and
4434 Added SilcAskPassphrase callback that the application calls
4435 to deliver the passphrase to the library.
4437 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4438 The public key verification and especially a certificate
4439 verification is asynchronous procedure.
4441 Added new SILC_SKE_STATUS_PENDING status to indicate the
4442 request is pending and a callback will be called to finalize
4445 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4446 indicate that remote end did not send its public key (or
4447 certificate), even though we require it. Added check for this
4448 condition in the SKE. This was a security bug, now fixed.
4450 Defined new SilcSKEVerifyCbCompletion callback that is called
4451 when the verification process is completed.
4453 The affected files lib/silcske/silcske_status.h and
4454 lib/silcske/silcske.[ch].
4456 * Changed the verify_public_key client operation to be async
4457 as well. Defined SilcVerifyPublicKey callback that is used to
4458 indicate the success of the public key verification process.
4460 Changed the server and client to use the new async client
4463 * Changed the Irssi SILC client's internal scheduler to be called
4464 twice as many times as it used to be. As a result the client
4465 should be a bit faster now. Affected file is
4466 irssi/src/silc/core/silc-core.c.
4468 * Added support to Irssi SILC client of asynchronous public key
4469 verification and passphrase inquiry. Affected file is
4470 irssi/src/silc/core/silc-core.c.
4472 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Do not say "You have left channel %s" in client library.
4475 Moved it to the application. Affected files are
4476 lib/silcclient/command.c and silc/client_ops.c.
4478 * Fixed silc_client_get_clients. Command context was not
4479 duplicated and was freed memory in the callback. Affected
4480 file lib/silcclient/idlist.c.
4482 * Do not say "you are now talking..." on JOIN command in the
4483 client library. The appliation must handle it.
4485 * Do not say ".. changed topic to" in command reply in the
4486 client libary. The application must handle it.
4488 * Fixed TOPIC command sending in the client library.
4490 * Fixed a memory leak in silc_client_command_free in the file
4491 lib/silcclient/command.c.
4493 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Imported a modified version of Irssi client to the source tree.
4496 The Irssi will be used to create a new client called
4497 Irssi SILC. Imported to irssi/.
4499 Added silc_core_init_finish function to the Irssi. Affected
4500 file irssi/configure.in.
4502 A lot changes in the Makefile.ams around the irssi tree.
4504 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Do not rehash if the new size is same as the old size of the
4507 hash table, in the silc_hash_table_rehash*. The affected file
4508 lib/silcutil/silchashtable.c.
4510 * Replaced hash_table_del_by_context calls from the server
4511 (when channel->user_list and client->channels) to the
4512 hash_table_del as it is sufficient and faster.
4514 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Added silc_hash_table_list, silc_hash_table_get and the
4517 SilcHashTableList structure to provide an alternative way to
4518 traverse the hash table. The affected files are
4519 lib/silcutil/silchashtable.[ch].
4521 * Changed the server's idlist routines to use the hash table
4522 routines to optimize the code.
4524 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Replaced the client entry's `channel' list and channel entry's
4527 `user_list' list to hash tables for optimized lookup. Changed
4528 the code to use the hash table interface around the code.
4529 Affected file lib/silcd/idlist.[ch].
4531 * Added `auto_rehash' boolean argument to the function
4532 silc_hash_table_alloc to indicate whether the hash table should
4533 auto-rehash when it thinks is appropriate time. It will
4534 increase the hash table size if the there is twice as much
4535 entries in the table than the size of the table, and will
4536 decrease the size if there are twice as less entries than
4537 the size of the table.
4539 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4543 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * silc_idcache_purge_by_context deletes the entry now by context
4546 as it is supposed to do. Affected file lib/silccore/idcache.c.
4548 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4549 client is not anymore valid (WHOWAS givens the info) and not
4550 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4552 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Removed the `data' and `data_len' arguments from the ID Cache
4555 interfaces and added `name' argument. ID Cache does not handle
4556 anymore the binary data only a names associated with given ID.
4558 * When hashing a Client ID with silc_hash_id the entire ID is
4559 not hashed anymore, instead only the hash of the Client ID is
4560 hashed. This way we can access the Client ID from the cache
4561 with Client ID but with the hash of the ID (which is a hash of
4562 the nickname) as well without any difference in performance.
4564 Added also silc_idcache_find_by_id_one_ext to do one on one
4565 searching when we have the actual ID. Added also function
4566 silc_hash_client_id_compare. The affected files are
4567 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4569 * When hashing the name associated with a ID it is always done
4570 in lowercase. This way we can access the cache without worrying
4571 about case-sensitivity, even though, for example nicknames are
4574 * Fixed a bug in server with channel message sending. It put
4575 wrong ID type as destination ID. The affected file
4576 silcd/packet_send.c.
4578 * silc_idcache_del_by_context now deletes from all hash tables
4579 by context. Affected file lib/silccore/idcache.c.
4581 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Changed the client library to use the new ID Cache interface.
4584 Changes around the source tree.
4586 * Added silc_hash_table_rehash_ext to rehash with specific
4587 hash function. Affected file lib/silcutil/silchashtable.[ch].
4589 * Added silc_hash_string_compare to compare two strings in the
4590 hash table. Affected file lib/silcutil/silcutil.[ch].
4592 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Added new function silc_idcache_del_by_context into the
4595 lib/silccore/idcache.[ch].
4597 * Changed the server's ID list routines to use the new ID Cache
4598 interface. Changes around the source tree.
4600 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Added silc_hash_table_del[_by_context]_ext functions in to the
4603 lib/silcutil/silchashtable.[ch].
4605 Removed silc_hash_table_find_all* routines and added new
4606 silc_hash_table_find_foreach to replace them.
4608 Added silc_hash_table_replace_ext function as extended
4609 replacing function. Separated the simple hash table interface
4610 from the extended hash table interface in the file
4611 lib/silcutil/silchashtable.h.
4613 * Fixed minor bugs and changed it to use some of the new
4614 hash table functions in lib/silccore/idcache.c
4616 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Added new function silc_hash_table_find_all to return all keys
4619 in the hash table by the specified key. As the hash table is
4620 collision resistant it also makes it possible to have several
4621 duplicate keys in the hash table. This function may be used to
4622 find all of the keys from the hash.
4624 Added user_context arguments to the SilcHashFunction,
4625 SilcHashCompare and SilcHashDestructor to deliver user specified
4628 Added new fuctions silc_hash_table_find[_all]_ext to do
4629 extended lookup with specified hash and compare functions and
4630 specified user contexts.
4632 Added new function silc_hash_table_add_ext to add the key
4633 with specified hash function and user context.
4635 Added new function silc_hash_table_foreach to traverse all
4636 entrys in the hash table. Added SilcHashForeach callback
4639 Added new function silc_hash_table_del_by_context to delete
4640 the entry only if the context associated with the key matches.
4642 Affected files are lib/silcutil/silchashtable.[ch].
4644 * Removed silc_hash_[server/client/channel]_id and added just
4645 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4646 silc_hash_id_compare to compare two ID's using as the hash table
4647 comparison function. Added also silc_hash_data to hash
4648 binary data and silc_hash_data_compare to compare it.
4650 * Removed silc_idlist_find_client_by_hash as it is not needed
4651 anymore. Affected file silcd/idlist.[ch].
4653 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4654 to use internally the SilcHashTable. The new ID Cache is a lot
4655 faster than the old one. Some of the ID Cache interface was also
4656 rewritten and obsolete and stupid functions were removed.
4658 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Added entry_count field to the SilcHashTable to keep the number
4661 of the entries in the table. Implemented the function
4662 silc_hash_table_rehash. Added new function
4663 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4665 Fixed a minor bug in silc_hash_table_free.
4667 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4668 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4669 into the lib/silcutil/silcutil.[ch].
4671 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Implemented a collision resistant hash table into the
4674 lib/silcutil/silchashtable[ch]. See the header and the source
4675 for the SilcHashTable API.
4677 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Merged dotconf version 1.0.2 into lib/dotconf.
4681 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Do not compile anything in lib/silcsim/* if the SIM support
4684 is not enabled. The tree should now compile without problems
4687 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Compiled the SILC under cygwin. Compiled and tested briefly
4690 without problems. More tests needed. The SIMs didn't compile
4693 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4695 * Fixed possible crash in silc_get_username in the
4696 lib/silcutil/silcutil.c.
4698 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Fixed a va_arg in silc/client_ops.c.
4702 * Oops, RC5 routines were named AES and caused some problems
4703 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4705 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * Added new SilcIDIP structure into the lib/silccore/id.h and
4708 replaced the old `ip' fields from all SILC ID's to that type.
4709 This is a step towards IPv6 support.
4711 The silc_id_get_len takes now the ID as an extra argument.
4712 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4713 both IPv4 and IPv6 based ID's.
4715 The affected files are lib/silccore/id.[ch] and other files
4716 around the tree using these routines.
4718 * Removed the ID length arguments in server from various
4719 silc_server_send_notify_* routines -> they are not needed
4722 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Fixed memory leak in silc_encode_pem_file in the file
4725 lib/silcutil/silcutil.c.
4727 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Check minor version as well in the SKE. Affected files are
4730 silcd/protocol.c and lib/silcclient/protocol.c.
4732 * Added --identifier option to the server so that an identifier
4733 can be when creating the public key for the server. Affected
4734 file is silcd/silcd.c.
4736 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4737 lib/silccrypt/silcpkcs.c.
4739 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Register default ciphers and stuff when using -C option with
4742 the server. Affected file sildc/silcd.c.
4744 * Put back the servers public key filename format, it is better
4745 than the new one. For now, the client keys are saved with the
4746 new filename format. The affected file silc/client_ops.c.
4748 * Implemented the Cipher API for the rest of the ciphers that
4749 did not implement it or implemented it the wrong way.
4751 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Register default ciphers and stuff when using the -S option
4754 in the client. Affected file silc/silc.c. Same also when
4755 creating new key pair with -C option.
4757 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Fixed the silc_verify_public_key client operation function to
4760 save the public keys differently. The fingerprint is now
4761 used as filename and not the hostname. This way also the
4762 client keys are saved uniquely and not with hostnames. The
4763 affected file is silc/client_ops.c.
4765 * Trimmed the silc_hash_fingerprint function to remove extra
4766 whitespaces from the end of the fingerprint. The affected
4767 file is lib/silccrypt/silchash.c.
4771 * Added silc_cipher_register_default function to register all
4772 default ciphers. It can be used when configuration files
4773 does not exist and the application does not want any specific
4774 ciphers in any specific order.
4776 The SilcDList is now used as silc_cipher_list dynamically
4777 allocated cipher list. Removed the static list all together
4778 and now all ciphers must be allocated to the dynamic list.
4779 The silc_cipher_alloc routine was changed to check only the
4782 All silc_cipher_* routines that used to return int returns
4785 The affected files lib/silccrypt/silccrypt.[ch].
4787 * The same thing was done to silc_hash_* as for silc_cipher_*
4788 routines. Affected files lib/silccrypt/silchash.[ch].
4790 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4791 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4792 Added also silc_pkcs_[un]register[_default] functions.
4793 Removed the data_context from the PKCS API.
4795 * Added silc_hmac_register_default function to register default
4796 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4797 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4798 to unregister all hmacs at once.
4800 * Register the default ciphers, hash functions, PKCSs and HMACs
4801 if client's configuration file does not exist. The affected
4804 * The client did not load the hash functions from the SIM
4805 modules at all. Added support for this. Affected file is
4806 silc/clientconfig.c.
4808 * When decoding public key with silc_pkcs_public_key_decode, check
4809 the supported algorithm only if PKCS are registered. Affected
4810 file lib/silccrypt/silcpkcs.c. The same was done with the
4811 silc_pkcs_private_key_decode.
4813 * Fixed the SILC List routines to keep the list always in order.
4814 It used to change the list's order when traversing the list but
4815 not it preserves the order. Affected file lib/trq/silclist.h.
4817 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Added the client library to use the SilcSocketConnection's
4820 reference counter (by silc_socket_dup) to prevent the bug that
4821 the socket object may be freed underneath async operation.
4823 * The name resolv library checking fixes in the configure.in.pre.
4826 * Created new version of the protocol drafts for future
4827 development. The -03 drafts are the ones that will be changed
4828 in the trunk now and the -02 will remain as they are.
4830 * Send list of CUMODE notifys to the router when announcing
4831 the channel users to the router. Affected file silcd/server.c.
4832 If the router receiving channel founder CUMODE for a channel
4833 that already has channel founder it will send CUMODE notify
4834 to the sender to remove the channel founder rights from the
4835 announced client. Affected file silcd/packet_receive.c.
4837 * The CUMODE notify may now use Server ID as well as the entity
4838 who changes the mode. Updated protocool specs.
4840 * Updated INSTALL and README files.
4842 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * New web pages in the http://silc.pspt.fi. The pages was
4849 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4851 * Implemented the [DenyConnectin] config section in the server.
4852 Added silc_server_config_denied_conn to check whether incoming
4853 connection is denied. Affected file silcd/serverconfig.[ch].
4855 * Do not check the ports when checking the incoming configuration
4856 data if the port is 0, meaning any. Affected file is
4857 silcd/serverconfig.c.
4859 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4861 * Fixed buffer overflow in silc_string_compare in the file
4862 lib/silcutil/silcutil.c.
4864 * Fixed double free in silc_server_command_leave in the file
4867 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4869 * Fixed the version checking in the server. Affected file is
4872 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Fixed the configuration data fetching when accepting new
4875 connections in the server. Affected file silcd/server.c.
4877 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Added `sender_entry' argument to the function
4880 silc_server_packet_relay_to_channel so that we can check
4881 whether some destination actually belongs to the same route
4882 the sender belongs (ie, we must not resend the packet to the
4883 sender). Affected file silcd/packet_send.[ch].
4885 * Added `servername' field to the SilcClientEntry in the server
4886 to hold the name of the server where client is from. Affected
4887 file is silcd/idlist.h.
4889 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Moved the channel message encrypting in the router betwen
4892 router connections from silc_server_channel_message to the
4893 silc_server_packet_relay_to_channel since we want to check
4894 whether we have anybody channel before encrypting anything.
4895 Affected files silcd/packet_[receive/send].c.
4897 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Fixed the [AdminConnection] server config section to support
4900 multiple entries. Affected file silcd/serverconfig.c.
4902 * Added support into the server to check the validity of the
4903 incoming connection before executing any KE or authentication
4906 * The connection configuration is now saved to the KE and
4907 connection auth protocol contexts and not fetched anymore in
4908 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4910 * The local hosts listenning address and port is also resolved
4911 now when starting the server. We want to have the socket object
4912 to include the real address and port for the listener. Added
4913 new function silc_net_check_local_by_sock into the files
4914 lib/silcutil/silcnet.[ch].
4916 * Fixed a broadcast bug in server -> do not broadcast if we
4919 * Fixed a routing bug. Do not route broadcast packets ever.
4920 Broadcast packets must be processed always and not routed since
4921 they may be destined to some other host than yourself and thus
4922 would get routed without no good reason. Affected file is
4925 * Added function silc_server_config_is_primary_route to check
4926 whether primary router connection has been configured (a router
4927 configuration that we are initiating). If there is not, we
4928 will assume that there is only two routers in the SILC network
4929 and we will use the incoming router connection as our primary
4930 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4932 * Changed the order of the broadcasting. Broadcast _after_ the
4933 packet has been processed not before. Affected file is
4936 * Fixed a [ClientConnection] parsing bug. The port was never
4937 parsed correctly thus resulting to port 0. Affected file
4938 silcd/serverconfig.c.
4940 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4941 argument and did not set the broadcast packet flag. Affected
4942 file silcd/packet_send.c. Fixed same bug in the function
4943 silc_server_send_notify as well.
4945 * If we receive NEW_ID packet for our own ID in the server, ignore
4948 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Removed the nickname from the Private Message Payload.
4953 Updated the code and the protocol specs.
4955 * Updated protocol specs for submitting to the IETF.
4957 * Tweaked the Random Number Generator a bit. Affected file
4958 lib/silccrypt/silcrng.c. Exported a new function
4959 silc_rng_[global]_add_noise which can be used to add more
4962 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Do not parse packets with different timeout when protocol
4965 is active -> may cause problem with rekey. Affected file
4968 * When server receives signoff notify it must not create
4969 new channel key if the client is on any channels since the
4970 sender of the signoff notify will create it.
4972 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4974 * Added printing of error messages during SKE protocol from the
4975 failure packet sent by server during SKE. Affected file
4978 * Removed the client's failure_callback handling with timeout
4979 and handle it immediately when received.
4981 * The SKE library returned wrong type in SUCCESS and FAILURE
4982 packets. They must be 32 bit MSB not 16 bit MSB.
4984 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Ok, rewrote the logic of the re-key and now it seems to work.
4987 I tested it on high traffic with frequent re-keys without
4988 problems. Added hmac_receive (and renamed hmac to hmac_send)
4989 in SilcClientConnection in lib/silcclient/client.h and
4990 in SilcIDListData in silcd/idlist.h. Also, removed the
4991 SilcPacketParserContext's cipher and hmac fields as they are
4992 not needed anymore and actually caused some problems when
4993 the ciphers and hmac's changed underneath the packet parser.
4995 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * If re-key protocol is active then process the incoming packets
4998 synchronously since we must assure that icoming packets encrypted
4999 with the old key is processed before the new keys is set to
5000 use. This is true other packets than for REKEY packets.
5001 Affected file silcd/server.c. The same was done to client library
5002 as well, affected file lib/silcclient/client.c.
5004 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Fixed bug in client and server to accept the force send if
5007 the packet is send from silc_[server/client]_packet_process
5008 function. Otherwise the packets are never delivered, oops.
5010 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Disable force sending of packets when REKEY protocol is active.
5013 We must assure that no packet is sent directly when rekey is
5014 performed. All packets must be sent through packet queue.
5015 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5016 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5017 function is silc_[server/client]_packet_send_real to check
5020 * Replaced the SIM paths from example config files to
5021 /usr/local/modules. Also, make install creates now
5022 /usr/local/silc/logs directory to hold all the SILC server
5025 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Made the configure.in.pre work on Solaris. Patch by salo.
5029 * Made all ciphers compatible with non-x86 machines. Defined
5030 CBC mode macros into lib/silccrypt/ciphers_def.h.
5032 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * Fixed the make install.
5036 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * When MAC computation fails the silc_packet_decrypt returned 0
5039 even though it was supposed to return -1. Fixed this. The
5040 affected file is lib/silccore/silcpacket.c.
5042 * Do not replace the config files in /etc/silc (in make install)
5043 if they already exist. Affected file ./Makefile.am.
5045 * Do not send re-key packets immediately but through packet queue.
5046 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5048 * Changed silc_net_check_host_by_sock to return FALSE if the
5049 IP/DNS could not be resolved. Though, it returns the IP address
5050 now even if it could not resolve it (but returns also FALSE).
5051 Affected file lib/silcutil/silcnet.[ch].
5053 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5055 * Added silc_pkcs_decode_identifier to decode the public key's
5056 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5057 Added also silc_pkcs_free_identifier. Added also new context
5058 SilcPublicKeyIdentifier.
5060 * Added -S option to the silc client. It is used to dump the
5061 contents of the specified public key file.
5063 * Changed the PKCS api to return the public key length when
5064 setting the public key.
5066 * Fixed a fatal bug in the public and private key file loading.
5067 Affected file lib/silccrypt/silcpkcs.c.
5069 * Execute the packet parsing for client with zero (0) timeout
5070 if the protocol is active. Affected file silcd/server.c.
5072 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Made the key generation options to the silcd program. Added
5075 -C option, equivalent to client's option.
5077 * Added new [ServerKeys] config section to the server. It
5078 configures the server's public and private key.
5080 * Defined generic Public Key Payload into the protocol
5081 specification to send specific type of public keys and
5084 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5085 public key or certificate.
5087 * Implemented the GETKEY command to the server and to the
5088 client library and on user interface.
5090 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5102 the number of the SKE group that is used with PFS in re-key.
5103 Affected file silcd/idlist.h.
5105 * Added PFS re-key support to the server. Affected file is
5108 * Added silc_protocol_cancel to cancel execution of the next
5109 state of the protocol. Affected file is
5110 lib/silccore/silcprotocol.[ch].
5112 * Added the re-key support with and without PFS to the client
5113 library. Re-key is performed once in an hour, by default.
5115 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.

5122 lib/silcclient/client.h.
5126 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Do not ask whether user wants to use the negotiated private key
5129 for private messages, just use it. Affected file is
5130 silc/local_command.c.
5132 * Added `send_enc_key' and `enc_key_len' fields to the
5133 SilcIDListData structure since they are needed in the re-key
5134 phase. Affected file is silcd/idlist.[ch].

5148 the PFS is to be performed in the re-key. Affected file is
5151 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5154 int64 of at least the xintXX size. If void * is less that 4
5155 bytes uint32 * will be used. Defined bool as boolean.
5157 * Changed _ALL_ unsigned long and unsigned int to uint32,
5158 unsgined short to uint16 in the source tree.
5160 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5161 not handle clients that has entry->data.registered == FALSE.
5162 They are not in the network anymore. Affected file is
5165 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Implemented the sending of the SERVER_SIGNOFF notify in the
5168 server. Affected file is silcd/server.c.
5170 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

5175 Affected file silcd/packet_receive.c.
5177 * Implemented the SERVER_SIGNOFF notify handling in the client
5178 library. Affected file lib/silcclient/client_notify.c. Also,
5179 implemnted the printing of the SERVER_SIGNOFF info to the
5180 application. Affected file silc/client_ops.c.
5182 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5183 if the deleting was successful. Affected file silcd/idlist.[ch].
5185 * Added support for public key authentication in the connection
5186 authentication protocol in the client library. Affected file
5187 lib/silcclient/protocol.c.
5189 * Changed the server's silc_idlist_get_clients_by_* interface
5190 to support already allocated array so that new entries may be
5191 added to pre-allocated array. Affected file silcd/idlist.[ch].
5192 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5193 and command replies.
5195 * All command reply functions in the server now calls the
5196 pending command callback even if error occured. This way the
5197 error will be delivered to the client as well. Affected files
5198 silcd/command.c and silcd/command_reply.c.
5200 * Fixed INFO command to return local server's info if no server
5201 was provided. Affected file lib/silcclient/command.c.
5203 * Removed RESTART command for good. Updated the code and the
5206 * Rewrote parts of the task system. It is a bit simpler now.
5207 Removed unsued task priorities. The affected files are
5208 lib/silcutil/silctask.[ch].
5210 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Moved the USERS printing from the library to the application.
5213 Affected files lib/silcclient/command.c and silc/client_ops.c.
5215 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5219 * Added channel key re-key support. The re-key is perfomed
5220 only by the router and is done once in an hour. Added `rekey'
5221 field to the SilcChannelEntry in the server. Affected files
5222 silcd/server.c and silcd/idlist.h.
5224 * Added silc_task_unregister_by_context into the file
5225 lib/silcutil/silctask.[ch].

5229 * Added SILC_UMODE_GONE mode to indicate when the client is not
5230 present in the SILC network. Added also support to the local
5231 command AWAY that will set this mode. Added support of showing
5232 "xxx is gone" in WHOIS command. The USERS command shows the
5233 gone status as well.
5235 * Fixed setting server and router operator privileges in the
5236 server's UMODE command. Affected file silcd/command.c.
5238 * Merged the SKE KE1 and KE2 payloads into one payload. The
5239 new KE payload is equivalent to the old KE2 payload.
5241 Cleaned up the SKE Start Payload parsing. It now uses the
5242 simple buffer unformatting to do the parsing. A lot faster
5245 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5246 to the SKE that is used to indicate whether both of the SKE
5247 parties should perform authentication. By default only the
5248 responder performs authentication. By setting this flag also
5249 the initiator must do authentication. By default it is unset
5250 since in normal SKE case, client to server connection, only
5251 the responder should do authentication. When doing SKE between
5252 two clients both should perform authentication. Updated the
5253 code and the protocol specs.
5255 * A little fix to IDENTIFY command in the server. Search the
5256 client first by hash not nickname. Affected file is
5259 * Fixed the silc_client_close_connection to support closing
5260 the client to client connections wihtout deleting too much
5261 data. Affected file lib/silcclient/client.c.
5263 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5264 are received if protocol used to be active but is not anymore
5265 the application would crash due to NULL pointer dereference.
5266 Affected files silcd/server.c and lib/silcclient/client.c.
5268 * Added `hash' field to the SilcClientConnection to include
5269 the hash function negotiated in the SKE protocol.
5271 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5272 to set the channel founder authentication data. A client can
5273 claim the founder rights later by providing the authentication
5274 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5275 This way the channel founder can regain the channel founder
5276 privileges even it is left the channel. This works only on
5277 local server and the client must be connected to the same
5278 server to be able to regain the founder rights. Updated the
5279 protocol specs accordingly.
5281 Added support to the CMODE command in the client to set the
5282 founder auth data. Read the README to see how to set it.
5284 Added support to the CUMODE command to claim the founder
5285 rights. Read the README to see how to do it.
5287 Added support for the founder authentication to the Channel
5288 Entry in the server. Affected file silcd/idlist.h.
5290 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5291 server's CMODE command. Affected file silcd/command.c.
5293 * Added the following new functions into lib/silccore/silcauth.[ch]:
5294 silc_auth_get_method and silc_auth_get_data.
5296 * The server now saves the remote hosts public key to the
5297 SilcIDListData pointer. Affected file silcd/protocol.c.
5299 * The normal server now does not remove the channel entry from
5300 the cache if the founder authentication data is set. It used
5301 to remove it if the founder was the last one on the channel on
5302 the server and left the channel. The auth data is saved and
5303 if the channel is re-joined later the old entry is used with
5304 the old auth data. Affected files silcd/command_reply.c and
5307 * Removed the `pkcs' field from the SilcIDListData structure
5308 in the server; it is not used. Affected file silcd/idlist.h.
5310 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Fixed packet processing on slow links. Partial packets were
5313 never re-processed because the incoming data buffer was cleared
5314 by the application. Application must not directly clear the
5315 sock->inbuf, the packet processing routines handle it. Fixed
5316 this in client library and in server.
5318 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Fixed the WHOIS and IDENTIFY send reply function to really
5321 check whether to send list or just one entry. Affected file
5324 * Cleaned up the LEAVE command's channel key distribution. The
5325 affected file silcd/command.c.
5327 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5328 can enforce the channel mode as well. In that case the ID
5329 includes the ID of the server. The code now enforces the
5330 mode change if the router have different mode than the server.
5332 * The notify client operation with CMODE_CHANGE notify can now
5333 return NULL client_entry pointer if the CMODE was not changed
5334 by client. Application must check for this.
5336 * Added <Server ID> argument to INFO command to support server
5337 info fetching by Server ID.
5339 * Added silc_server_announce_get_channel_users to get assembled
5340 packets of channel users of the specified channel. Affected
5341 file silcd/server.[ch].
5343 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5344 was freed underneath the ID Cache.
5346 * Re-announce clients when the server received CHANNEL_CHANGE
5347 notify from the router. Affected file silcd/packet_send.c.
5349 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5352 crashed since it did not handle the fact that there is no cipher
5353 called "3" and didn't check the error condition. Now fixed.
5355 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5356 flag. It can be used to send message requests.
5358 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * Implemented the RESTART command in the client.
5362 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5363 notice type messages. Added notice printing to the user
5366 * The channel keys are not re-generated if the channel's mode
5367 is PRIVKEY, ie private key on the channel exists. Affected
5368 files silcd/server.c and silcd/command.c.
5370 * Fixed a little bug in channel message delivery when channel
5371 private keys are set in the server. Affected file is
5372 silcd/packet_send.c.
5374 * Changed the setting on channel->on_channel = TRUE from the
5375 silc_client_save_channel_key to the JOIN command reply. The
5376 key payload is not received if the private channel key is set.
5377 Affected file lib/silcclient/command_reply.c and the
5378 lib/silcclient/client_channel.c.
5380 * When the CMODE_CHANGE notify is sent and the channel private
5381 key mode is removed the channel key must be re-generated in
5382 other cells as well. Added this support for the router in the
5383 silcd/packet_receive.c.
5385 * Added new local command NOTICE to send notice message on
5386 channel. Affected file silc/local_command.[ch].
5388 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Added new local command ME to the client. It is used to send
5391 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5392 some action. Affected file silc/local_command.[ch].
5394 * Changed channel_message and private_message client operations
5395 to deliver the message flags to the application. Added also
5396 the `flags' arguments to the silc_client_send_channel_message
5397 and silc_client_send_private_message functions. Affected file
5400 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Redefined the Private Message Payload to support private message
5403 keys and to support the new private message flags. Updated
5404 the protocol specs. Flags makes it possible to have for example
5405 CTCP style messages.
5407 * Added new type SilcPrivateMessagePayload and defined an API
5408 for it in the lib/silcclient/silcprivate.[ch].
5410 * Tested private message private keys successfully. Tested the
5411 private message key set, unset and list commands with the new
5414 * Redefined the Channel Message Payload to include the channel
5415 message flags (equal with private message flags) to support
5416 for example CTCP style messages.
5418 * Defined some of the message (for channel and private message)
5419 flags. Updated the protocol specs and added the flags to the
5420 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5422 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Added SilcKeyAgreementStatus type to the key agreement routines
5425 to indicate the current status and error if one occured.
5426 The status types are defined in the lib/silcclient/silcapi.h.
5428 * Added new local command KEY that is used to set and unset private
5429 keys for channels, set and unset private keys for private messages
5430 with remote clients and to send key agreement requests and
5431 negotiate the key agreement protocol with remote client. The
5432 key agreement is supported only to negotiate private message keys,
5433 it currently cannot be used to negotiate private keys for channels,
5434 as it is not convenient for that purpose.
5436 * Fixed a minor pending callback setting bug in the function
5437 silc_client_get_client_by_id_resolve, now the function works.
5438 Affected file lib/silcclient/idlist.c.
5440 * Added function silc_net_get_local_port to get local bound
5441 port by socket. Added to lib/silcutil/silcnet.[ch].
5443 * Added `sockets' and `sockets_count' fields to the SilcClient
5444 object. They hold the sockets of the listenning sockets in
5445 the client. Listenning sockets may be for example the key
5446 agreement server. Affected file lib/silcclient/client.[ch].
5447 Added functions the silc_client_add_socket and the
5448 silc_client_del_socket. They are exported to the application
5451 * Added ~./silc/clientkeys to support other client's public keys.
5453 * Renamed verify_server_key client operation to verify_public_key
5454 and added one argument to indicate the type of the connection
5455 (server, client etc.).
5457 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * Added silc_server_connection_auth_request to handle the
5460 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5461 silcd/packet_receive.[ch].
5463 * Added silc_server_send_connection_auth_request into the
5464 silcd/packet_send.c to send the connection auth request packet.
5466 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5469 * Fixed the public key authentication in responder side in the
5470 server. The `auth_data' pointer includes the SilcPublicKey
5471 not the path to the public key. Affected file silcd/protocol.c.
5473 * Implemented the public key authentication in the initiator side
5474 in the server. Affected file silcd/protocol.c.
5476 * Removed the [RedirectClient] config section from the server
5477 configuration. Is not needed and I don't want to implement it.
5479 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Cleaned up the CMODE command in the server. It now works
5482 correctly and supports all the modes defined in the protocol.
5483 Affected file is silcd/command.c.
5485 * Added `hmac_name' field to the SilcChannelEntry in the server
5486 to hold the default HMAC of the channel. It can be set when
5487 creating the channel (with JOIN command). Affected files
5490 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5491 type to indicate the change of the current cipher and hmac
5492 on the channel. Client can safely ignore the <cipher> argument
5493 (if it chooses to do so) since the CHANNEL_KEY packet will
5494 force the channel key change anyway. The <hmac> argument is
5495 important since the client is responsible of setting the new
5496 HMAC and the hmac key into use.
5498 * Fixed the CMODE command in the client library as well.
5500 * Tested CMODE command in router environment successfully.
5502 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5504 * Show the version of the remote client (or server) when connecting
5505 to the server. It is logged to the log file. Affected file
5506 is silcd/protocol.c.
5508 * Fixed the KILLED notify handling in the client library. The
5509 client must be removed from all channels when receiving the
5512 Also, do not remove the client entry when giving the KILL
5513 command but when the KILLED notify is received.
5515 * Removed silc_idlist_find_client_by_nickname from the server.
5516 Not needed anymore. Affected files silcd/idlist.[ch].
5518 * Implemented the CHANNEL_CHANGE notify type handling to the
5519 server. Affected file silcd/server.c.
5523 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Added silc_server_send_notify_invite to send the INVITE
5526 notify between routers.
5528 * Implemented the INVITE command correctly to the server.
5530 * Implemented the INVITE notify type handling in the server.
5532 * Implemented the INVITE command to the client library and on the
5535 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Added function silc_server_get_client_resolve to find the
5538 client entry by ID from all ID lists and then resolve it
5539 (using WHOIS) if it cannot be found. Affected file is
5542 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Implemented the BAN command to the client library.
5546 * The JOIN command in the server now checks the invite list
5549 * Changed the silc_command_reply_payload_encode_va and the
5550 silc_command_payload_encode_va to support that if argument is
5551 NULL it ignores and checks the next argument. Affected file
5552 lib/silccore/silccommand.c.
5554 * Added silc_server_send_notify_ban to send the BAN notify
5555 type between routers.
5557 * Chaned the silc_notify_payload_encode to support that if
5558 argument is NULL it ignores and checks the next argument.
5559 Affected file lib/silccore/silcnotify.c.
5561 * Tested ban lists in router environment successfully.
5563 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Implemented BAN command to the server, in silcd/command.[ch].
5567 * Removed the BAN and INVITE_LIST modes from the CMODE command
5570 * Added function silc_string_match to regex match two strings.
5571 Affected files lib/silcutil/silcutil.[ch].
5573 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5575 * Redefined parts of the SilcChannelEntry in the server to support
5576 the new ban and invite lists.
5578 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Redefined the INVITE command. The same command can be used to
5581 invite individuals to the channel but also to manage the invite
5582 list of the channel (to add to and remove from the invite list).
5583 Updated the protocol specs.
5585 * Added new command SILC_COMMAND_BAN that can be used to manage
5586 the ban list of the channel. Updated the protocol specs.
5588 * Removed the channel modes: the SILC_CMODE_BAN and the
5589 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5590 in the CMODE command. The equivalent features are now available
5591 using INVITE and BAN commands. Updated the protocol specs.
5593 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5594 in the network about change in the current ban list. The notify
5595 type is not used by the client.
5597 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5598 support the invite lists.
5600 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Added new function silc_string_regexify that converts string
5603 including wildcard characters into regex string that can
5604 be used by the GNU regex library. Added into the file
5605 lib/silcutil/silcutil.[ch].
5607 Added silc_string_regex_combine to combine to regex strings
5608 into one so that they can be used as one regex string by
5609 the GNU regex library. Added into the file
5610 lib/silcutil/silcutil.[ch].
5612 Added silc_string_regex_match to match two strings. It returns
5613 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5615 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5617 * Imported GNU regex to the soruce tree into lib/contrib.
5618 Fixed some compiler warning from the regex.c.
5620 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5622 * Fixed MOTD command in the server to work in router environment.
5624 * Fixed the MOTD command in the client library to support
5625 the server argument in the command.
5627 * Added `nickname_len' argument to the silc_idlist_add_client
5628 in the server, as the `nickname' argument may be binary data
5631 * Added silc_idlist_get_channels to return all channels from
5634 * Implemented LIST command to the server. Affected file is
5637 * Implemented the LIST command to the client library and on the
5640 * Added [<user count>] argument to the LIST command reply.
5641 With private channels the user count is not shown.
5643 * Updated TODO and README.
5645 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * The client entry's data.registered must be TRUE even with
5648 global client entry on global client list. The data.registered
5649 is used to check whether the client is anymore in the network,
5650 for example with WHOWAS command so it must be valid.
5652 * Fixed the WHOWAS command in the server. It now actually works
5653 in router environment. Added function into silcd/command_reply.c
5654 silc_server_command_reply_whowas_save.
5656 * Added silc_idlist_purge function to the silcd/idlist.c
5657 to periodically purge the ID Cache.
5659 * Fixed INFO command in the server. It works now in router
5660 environment. Added <server name> argument to the INFO command
5661 reply. Updated the protocol specs.
5663 * Fixed minor bug in silc_idcache_purge to not purge if the
5664 expire value is zero.
5666 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5667 they were buggy because of the WHOWAS information.
5669 * Fixed local command MSG to handle the async resolving of
5670 the remote client properly. It used to fail the first MSG.
5671 Affected file silc/local_command.c.
5673 * Added `data_len' field to SilcIDCache context.
5675 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * Update TODO. Todo in commands in the server.
5679 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5682 used by routers as broadcast packet to inform other routers
5683 about the changed user mode.
5685 Implemented the notify handling in the server. Affected file is
5686 silcd/packet_receive.c. Added the function
5687 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5689 * Added new generic Channel Payload and deprecated the New Channel
5690 Payload. The New Channel Payload is now the generic Channel
5693 * Added new argument `mode' to the silc_server_send_new_channel
5694 as it is required in the Channel Payload now.
5696 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5697 and created a new and real SilChannelPayload to represent the
5698 new generic Channel Payload. Implemented the encode/decode
5699 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5701 * Added silc_server_get_client_channel_list to return the list
5702 of channels the client has joined for WHOIS command reply.
5703 Affected file silcd/server.[ch].
5705 * Implemented the channel list sending in the WHOIS command reply
5706 in server and in the client.
5708 Implemented the channel list displaying on the user interface
5709 as well. Affected file silc/client_ops.c.
5711 * Added silc_channel_payload_parse_list to parse list of Channel
5712 Payloads. It returns SilcDList list of SilcChannelPayloads.
5713 Client for example can use this function to parse the list of
5714 channels it receives in the WHOIS command reply. The caller
5715 must free the list by calling silc_channel_payload_list_free.
5716 Affected files lib/silccore/silcchannel.[ch].
5718 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Added one new argument <user mode> to the WHOIS command reply
5721 to return the mode of the user in SILC. Updated the protocol
5724 Implemented it to the server and client.
5726 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Fixed the mode printing on the user interface on joining.
5729 Affected file silc/client_ops.c.
5731 * Implemented the UMODE command and user modes in general to the
5732 client library and to the user interface.
5734 * Implemented the UMODE command to the server.
5736 * The server now sends UNKNOWN_COMMAND error status if client sends
5737 unknown command. Affected file silcd/command.c.
5739 * All server commands now handle the command identifier the right
5740 way when sending the command reply to the client. The client can
5741 use to identify the command replies with the identifier.
5743 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * Added silc_server_get_client_route to resolve the route to
5746 the client indicated by the client ID. Affected file is
5749 * Added silc_server_relay_packet as general function to relay
5750 packet to arbitrary destination. This deprecates functions
5751 like _send_private_message_key, _relay_notify etc. Affected
5752 file is silcd/packet_send.[ch].
5754 Removed silc_server_send_key_agreement,
5755 silc_server_send_private_message_key and
5756 silc_server_packet_relay_notify functions from the file
5757 silcd/packet_send.[ch].
5761 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5762 server. Affected file silcd/packet_receive.[ch].
5764 * Implemented the KILL command to the client. Implemented the
5765 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5766 Affected files lib/silcclient/command[_reply].c and
5767 lib/silcclient/client_notify.c. Implemented the KILL notify
5768 printing in the user inteface.
5770 * Fixed a lot silc_parse_nick memory leaks from the client
5771 library in the file lib/silcclient/command.c.
5773 * Changed the silc_server_send_notify_on_channels's `sender'
5774 argument from SilcSocketConnection to SilcClientEntry to
5775 check the sender as entry and not as connection object and not
5776 to send to the client provided as argument. The affected file
5777 is silcd/packet_send.[ch].
5779 * The notify packets that are destined directly to the client used
5780 to not to be processed by the server. Now changed that and the
5781 server processes all notify packets. After relaying the packet
5782 to the client the notify packet is processed in the server.
5784 * The silc_server_free_client_data now checks whether there is
5785 pending outgoing traffic for the client and purges the data to
5786 the network before removing the client entry.
5788 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5791 an client is killed from the SILC Network. Updated the protocol
5794 Added new function silc_server_send_notify_killed to the
5795 silcd/packet_send.[ch].
5797 * Added function silc_server_packet_relay_notify to relay notify
5798 packets that are destined directly to a client. In this case
5799 the server does not process the notify packets but merely relays
5800 it to the client. Affected file silcd/packet_send.[ch].
5802 Added also silc_server_packet_process_relay_notify to check
5803 whereto relay the notify. Affected file is
5804 silcd/packet_receive.[ch].
5806 * Implemented the KILL command to the server.
5810 * Added the backup schema desgined last fall to the protocol
5811 specs for everyone to see. The specification is in the
5812 *-spec-xx.txt draft and the packet type definitions for the
5813 backup routers is in *-pp-xx.txt draft. Thusly, added also
5814 new packet type SILC_PACKET_CELL_ROUTERS.
5816 * A big security problem in the implementation discovered. The
5817 signoff of an client did not cause new channel key generation
5818 which it of course should've done. The channel keys must be
5819 always re-generated when client leaves (or signoffs) the channel.
5820 The silc_server_remove_from_channels funtion now handles
5821 the channel key re-generation.
5823 * Added `sender' argument to the silc_server_send_notify_on_channels
5824 to not to send the client provided as argument. Affected file
5825 silcd/packet_send.[ch].
5827 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5829 * Implemented OPER and SILCOPER commands into the server and
5832 * Added silc_auth_verify and silc_auth_verify_data to verify
5833 the authentication directly from the authentication payload.
5834 It supports verifying both passphrase and public key based
5835 authentication. Affected file lib/silccore/silcauth.[ch].
5837 * Added `hash' field to the SilcIDListData structure. It is the
5838 hash negotiated in the SKE protocol. Affected file is
5841 * Slight redesigning of the SilcAuthPayload handling routines.
5842 Do not send SilcPKCS but SilcPublicKey as argument.
5844 * Implemented the public key authentication support to the
5845 serverconfig. The public key is loaded from the provided path
5846 and saved as authentication data to void * pointer. Thus,
5847 changed the unsigned char *auth_data to void *auth_data;
5849 * Fixed SHUTDOWN command to send the reply before the server
5850 is shutdown. :) Affected file silcd/command.c.
5852 * Fixed fatal bug in CONNECT command. The hostname was invalid
5853 memory and server crashed. Affected file silcd/command.c.
5855 * Fixed fatal bug in CLOSE command. The server_entry became
5856 invalid but was referenced later in the command. Affected file
5859 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Fixed fatal bug in failure packet handling. Server ignored
5862 the failure and thus crashed when it came.
5866 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5869 that the command may be executed only once in (about) 2 seconds.
5870 The old SILC_CF_LAG flag is same but allows command bursts up
5871 to five before limiting.
5873 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5874 server code. Various commands now includes the CF_LAG_STRICT
5875 flag to disallow any kind of miss-use of the command.
5877 * Fixed the silc_buffer_unformat to not to allocate any data
5878 if the length of the data is zero. It used to allocate the
5879 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5881 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Changed the format of AdminConnection configuration section
5884 in the server. Added username of the admin to the format.
5885 Affected files silcd/serverconfig.[ch].
5887 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5888 to return admin configuration data by host, username and/or
5891 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * Implemented WHOWAS command to the server. Added the functions:
5895 silc_server_command_whowas_parse,
5896 silc_server_command_whowas_send_reply,
5897 silc_server_command_whowas_from_client and
5898 silc_server_command_whowas_from_server
5900 * Added <Client ID> argument to the WHOWAS command reply. Updated
5901 the protocol specs accordingly.
5903 * Implemented WHOWAS command and command_reply to the client
5906 Implemented the WHOWAS printing on the user interface.
5908 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * Added new argument to the WHOWAS command reply, the real name.
5911 It is an optional argument. Updated the protocol specs.
5913 * Added SilcIDCacheDestructor callback that is registered when
5914 the SilcIDCache is allocated. The callback is called when
5915 an cache entry in the ID Cache expires, or is purged from the
5916 cache. Added into lib/silccore/idcache.[ch].
5918 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5919 to destruct the client entries when the cache entry expires.
5920 Other ID Cache's in server and in the client library ignores
5923 * If the ID Cache entry's `expire' field is zero then the entry
5924 never expires. Added boolean `expire' argument to the
5925 silc_idcache_add function in the lib/silccore/idcache.[ch].
5926 If it is TRUE the default expiry value is used.
5928 * Added silc_server_free_client_data_timeout that is registered
5929 when client disconnects. By default for 5 minutes we preserve
5930 the client entry for history - for WHOWAS command.
5932 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5934 * Added support to the server to enforce that commands are not
5935 executed more than once in 2 seconds. If server receives
5936 commands from client more frequently, timeout is registered
5937 to process the commands. Affected file silcd/command.c.
5938 Added new function silc_server_command_process_timeout.
5940 * Changed NICK_NOTIFY handling in client library to check that
5941 if the client's nickname was changed, so there is no need to
5942 resolve anything from the server.
5944 * Removed error printing from the WHOIS and IDENTIFY commands.
5945 If error occurs then it is ignored silently in the client library.
5946 The application, however, may map the received error to
5947 human readable error string. The application currently maps
5948 the NO_SUCH_NICKNAME error to string.
5950 * Made the command status message public to the application. Moved
5951 them from lib/silcclient/command_reply.c to
5952 lib/silcclient/command_reply.h. The application can map the
5953 received command status to the string with the
5954 silc_client_command_status_message function.
5956 * Added check to the server to check that client's ID is same
5957 as the Source ID in the packet the client sent. They must
5960 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5962 * Added dist-bzip hook to the Makefile.am to make bzip2
5963 compressed distributions.
5965 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Server now enforces the maximum length for the nickname and
5968 the channel as protocol specification dictates. 128 bytes for
5969 nickname and 256 bytes for channel name.
5971 * Moved the WHOIS printing to the application. The client libary
5972 does not print out the WHOIS information anymore, the application
5973 must do it. Renamed silc_client_command_reply_whois_print to
5974 the silc_client_command_reply_whois_save.
5976 The client's idle time is also sent to the application now, and
5977 the idle is shown on screen.
5979 * Added silc_client_command_reply_identify_save to save the
5980 received IDENTIFY entries.
5982 * Do not check for channel private keys in message sending and
5983 reception if the channel does not have the PRIVKEY mode set.
5984 Affected file lib/silclient/client_channel.c.
5986 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5988 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5989 just surfaced after chaning the JOIN procedure.
5991 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5993 * Added silc_client_get_clients_by_list to get client entries
5994 from Client ID list, that is returned for example by JOIN
5995 and USERS command replies. The application should use this
5996 function for example when JOIN command reply is received to
5997 resolve the clients already on the channel (library does not
5998 do that anymore as USERS command reply is not used in the JOIN
5999 procedure anymore). Affected files lib/silcclient/silcapi.h and
6000 lib/silcclient/idlist.c.
6002 * JOIN command reply and USERS command reply returns now SilcBuffer
6003 pointers instead of unsigned char pointers when returning
6004 the client list and mode list.
6006 * Added <Client ID> argument to the JOIN command reply, mainly
6007 for the server to identify for which client the command was
6008 originally sent. Updated protocol specs accordingly.
6010 * Added SilcDlist private_key pointer to the SilcChannelEntry
6011 in the client to support the channel private keys. Affected
6012 file is lib/silcclient/idlist.h.
6014 * Added SilcChannelPrivateKey argument to the function
6015 silc_client_send_channel_message so that application can choose
6016 to use specific private ke if it wants to. If it is not provided,
6017 the normal channel key is used, unless private keys are set.
6018 In this case the first (key that was added first) is used
6019 as the encryption key.
6021 * Implemented the support for channel private key handling.
6022 Implemented the following functions:
6024 silc_client_add_channel_private_key,
6025 silc_client_del_channel_private_keys,
6026 silc_client_del_channel_private_key,
6027 silc_client_list_channel_private_keys and
6028 silc_client_free_channel_private_keys
6030 Affected file lib/silcclient/client_channel.c.
6032 * Added the support for the private keys in the channel message
6033 sending and encryption and in the message reception and
6034 decryption. Affected funtions are
6035 silc_client_send_channel_message and silc_client_channel_message.
6037 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * Added SKE's key verify callback to the client library's
6040 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6042 * Removed the statement that server (or router) must send USERS
6043 command reply when joining to the channel so that the client
6044 knows who are on the channel. Instead, the client list and
6045 client's mode list is now sent in the JOIN command reply to the
6046 client who joined channel. This is better solution.
6048 * Added function silc_server_get_users_on_channel and function
6049 silc_server_save_users_on_channel to the silcd/server.[ch].
6051 * Removed function silc_server_command_send_users from the
6054 * Do not show topic on the client library anymore. The topic is
6055 sent in the command reply notify to the application and the
6056 application must show the topic now.
6058 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * Added client searching by nickname hash into the IDENTIFY and
6061 WHOIS commands in the server as they were clearly missing from
6062 them. Affected file is silcd/command.c.
6064 * Fixed a bug in private message receiving in the client library.
6065 The remote ID was freed and it wasn't supposed, now it is
6068 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * Minor fix to the channel payload; allocate the data area, as it
6071 needs to be of specific length.
6073 * If the key agreement port is zero then the operating
6074 system will define the bound port. Affected files are
6075 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6077 * Added new function silc_channel_payload_decrypt into the file
6078 lib/silccore/silcchannel.[ch].
6080 * Moved the channel message etc, check from silc_packet_decrypt
6081 to applications. The library calls now a generic
6082 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6083 when the packet is either normal or special. This was done to
6084 allow more wide range of checking that was not allowed when
6085 the code was in library. Now applications can do virtually any
6086 checks to the packet and return to the library the decision how
6087 the packet should be processed. Affected files are
6088 lib/silccore/silcpacket.[ch].
6090 Added silc_server_packet_decrypt_check to the server and
6091 silc_client_packet_decrypt_check to the client library.
6093 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6094 to send with specified source and destination information.
6096 * Channel message delivery between routers was broken after the
6097 channel key distribution was fixed earlier. The channel key
6098 was used be to distributed to other routers as well which is not
6099 allowed by the protocol. Now this is fixed and channel keys
6100 really are cell specific and the channel message delivery between
6101 routers comply with the protocol specification.
6103 * Fixed various commands in server to check also the global list
6104 for the channel entry and not just the local list. The affected
6105 file silcd/command.c.
6107 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6109 * Added assert()s to buffer formatting and unformatting routines
6110 to assert (if --enable-debug) when error occurs. Affected
6111 file: lib/silcutil/silcbuffmt.c.
6113 * Changed to auto-reconnect to check whether the remote host is
6114 router and register the re-connect timeout if it is. It used
6115 to check that whether we are normal server, but router must do
6116 auto-reconnect with another router as well. Affected file
6119 * Removed the [<key len>] option from CMODE command as the cipher
6120 name decides the key length, nowadays. See the defined ciphers
6121 from the protocol specification.
6123 * Added [<hmac>] option to the CMODE command to define the HMAC
6124 for the channel. Added SILC_CMODE_HMAC channel mode.
6126 * Added [<hmac>] option for the JOIN command so that user can
6127 select which HMAC is used to compute the MACs of the channel
6130 * Added Hmac field to the Channel Message Payload. The integrity
6131 of plaintext channel messages are now protected by computing
6132 MAC of the message and attaching the MAC to the payload. The
6133 MAC is encrypted. Now, it is clear that this causes some
6134 overhead to the size of the packet but rationale for this is that
6135 now the receiver can verify whether the channel message decrypted
6136 correctly and also when private keys are set for the channel the
6137 receiver can decrypt the packet with several keys and check from
6138 the MAC which key decrypted the message correctly.
6140 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6141 lib/silccrypt/silccipher.[ch].
6143 * Added silc_hash_len to return the digest length into the
6144 lib/silcrypt/silchash.[ch].
6146 * Rewrote parts of Silc Channel Payload interface in the
6147 lib/silccore/silcchannel.[ch]. The encode function now also
6148 encrypts the packet and parse function decrypts it.
6150 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Fixed a minor formatting bug in the SKE's key material processing.
6153 It actually might have processed the keys wrong way resulting
6156 * Redefined the mandatory HMAC algorithms and added new algorithms.
6157 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6158 and hmac-md5 truncated to 96 bits. The mandatory is now
6159 hmac-sha1-96. Rest are optional (including the one that used
6160 to be mandatory). Rationale for this is that the truncated HMAC
6161 length is sufficient from security point of view and can actually
6162 make the attack against the HMAC harder. Also, the truncated
6163 HMAC causes less overhead to the packets. See the RFC2104 for
6166 * Added new [hmac] configuration section. The SKE used to use
6167 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6168 is of course wrong. The official names that must be proposed in
6169 the SKE are the ones defined in the protocol specification
6170 (hmac-sha1-96 for example). The user can configure any hmac
6171 using any hash function configured in the [hash] section. At
6172 least, the mandatory must be configured.
6174 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6176 * Added HMAC list to the SKE proposal list. It has now both
6177 hash algorithm list and HMAC list. This makes the protocol
6178 incompatible with previous versions. The SKE now seems to work
6179 the way it is supposed to work, for the first time actually.
6181 * Defined plain Hash algorithms to the protocol specification.
6184 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6186 * Implemented support for key agreement packets into the server.
6187 Added functions silc_server_key_agreement and
6188 silc_server_send_key_agreement. Other than these functions,
6189 server has nothing to do with this packet.
6191 * Added support for private message key packets into the server.
6192 Added functions silc_server_private_message_key and
6193 silc_server_send_private_message_key.
6197 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6198 called in the protocol's final callback instead in the END
6199 protocol state. This makes a little more sense and in the same
6200 time in client we can use the same protocol routines for normal
6201 key exchange and to key agreement packet handling as well.
6203 * Added to both client's and server's KE protocol context the
6204 SilcSKEKeyMaterial pointer to save the key material. We will
6205 bring the key material to the protocol's final callback by doing
6206 this. The final callback must free the key material.
6208 * Added SKE's packet_send callback into client's KE protocol
6209 context so that the caller can choose what packet sending function
6210 is used. This way we can use different packet sending when
6211 doing normal SKE when doing key agreement packet handling (in
6212 the key agreement packet handling we do not want to encrypt
6215 * Implemented the responder side of the key agreement routines
6216 in the client. The client can now bind to specified port and
6217 accept incoming key negotiation. The key material is passed
6218 to the application after the protocol is over.
6220 * Implemented the processing of incoming Key Agreement packet
6221 in the client. Added function silc_client_key_agreement to
6224 * Implemented the intiator side of the key agreement routines
6225 in the client. The client can now initiate key agreement with
6226 another remote client. The key material is passed to the
6227 application after the protocol is over.
6229 * Created client_keyagr.c to include all the key agreement
6232 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6233 SILC_TASK_CALLBACK except that it is not static.
6235 * Created client_notify.c and moved the Notify packet handling
6236 from the client.[ch] into that file.
6238 * Created client_prvmsg.c and moved all private message and
6239 private message key routines from the client.[ch] into that file.
6241 * Create client_channel.c and moved all channel message and
6242 channel private key routines from the client.[ch] into that file.
6244 * Changed silc_client_get_client_by_id_resolve to resolve with
6245 WHOIS command instead of IDENTIFY command, in the file
6246 lib/silclient/idlist.c.
6248 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Implemented the SKE's responder side to the Client library.
6252 * When FAILURE is received to the protocol do not trust it
6253 blindly. Register a timeout to wait whether the remote closes
6254 the connection as it should do it, only after that process the
6255 actual failure. This was changed to both client and server.
6257 * Added client_internal.h to include some of the structures
6258 there instead of client.h in lib/silcclient/.
6260 * Added function silc_task_unregister_by_callback to unregister
6261 timeouts by the callback function.
6263 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Some "Incomplete WHOIS info" errors has been appearing on the
6266 log files. Took away the entry->userinfo check from WHOIS
6267 reply sending. The entry->userinfo is now " " if client did not
6268 provide one. I thought this was fixed earlier but something
6269 is wrong still. Let's see if the error still appears.
6271 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Fixed a minor bug in the login when the channel key is
6274 re-generated in the server. It used to generate the key in
6275 wrong order and thus caused problems in the channel traffic.
6277 * Fixed a minor bug in channel key distsribution after
6278 KICK command. The key was not sent to the router even though
6281 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Added silc_ske_process_key_material_data as generic routine
6284 to process any key material as the SILC protocol dictates. The
6285 function is used by the actual SKE library but can be used by
6286 applications as well. This relates to the private message keys
6287 and the channel private keys since they must be processed the
6288 same way the normal SILC session keys. The protocol dictates
6289 this. Affected files: lib/silcske/silcske.[ch].
6291 Added also silc_ske_free_key_material to free the
6292 SilcSKEKeyMaterial structure.
6294 * Defined silc_cipher_set_key function to set the key for
6295 cipher without using the object's method function. The affected
6296 files: lib/silccrypt/silccipher.[ch].
6298 * Implemented silc silc_client_add_private_message_key,
6299 silc_client_add_private_message_key_ske,
6300 silc_client_del_private_message_key,
6301 silc_client_list_private_message_keys and
6302 silc_client_free_private_message_keys functions in the
6305 Added functions silc_client_send_private_message_key to send
6306 the Private Message Key payload and silc_client_private_message_key
6307 to handle incoming Private Message Key payload.
6309 * Added Cipher field to the Private Message Key payload to set
6310 the cipher to be used. If ignored, the default cipher defined
6311 in the SILC protocol (aes-256-cbc) is used.
6313 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6315 * Removed lib/silcclient/ops.h file.
6317 Redefined parts of the SILC Client Library API. Created new
6318 file silcapi.h that deprecates the ops.h file and defines the
6319 published Client Library API. Defined also private message key
6320 API and channel private key API into the file.
6322 This is the file that the application must include from the
6323 SILC Client Library. Other files need not be included by
6324 the application anymore.
6326 * Added new key_agreement client operation callback and also
6327 defined the Key Agreement library API for the application.
6329 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6332 is used by clients to request key negotiation between another
6333 client in the SILC network. If the negotiation is started it
6334 is performed using the SKE protocol. The result of the
6335 negotiation, the secret key material, can be used for example
6336 as private message key.
6338 Implemented the Key Agreement payload into the files
6339 lib/silccore/silauth.[ch].
6341 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * Redefined ciphers for the SILC protocol. Added some new ciphers
6344 and defined the key lengths for the algorithms. Changed the
6345 code accordingly. The default key length is now 256 bits.
6347 * Fixed SKE key distribution function silc_ske_process_key_material
6348 when the key length is more than 128 bits. The default key
6349 length in SILC is now 256 bits.
6351 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6352 to indicate unsupported algorithm.
6354 * Renamed rijndael.c to aes.c and all functions as well.
6356 * Fixed a long standing channel key setting bug in client library.
6357 Weird that it has never surfaced before.
6359 * Fixed bug in channel deletion. If the entire channel is removed
6360 then it must also delete the references of the channel entry
6361 from the client's channel list as the client's channel entry and
6362 the channel's client entry share same memory.
6364 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * Implemented CONNECT and SHUTDOWN commands in the client.
6368 * Implemented CLOSE command to the client.
6370 * Added the function silc_idlist_find_server_by_name into the
6371 files silcd/idlist.[ch].
6373 Added the function silc_idlist_find_server_by_conn into the
6374 files silcd/idlist.[ch].
6376 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6378 * DIE command was renamed to SHUTDOWN. Updated the both code
6381 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6382 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6384 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6387 * Added function silc_server_create_connection function to create
6388 connection to remote router. My server implementation actually
6389 does not allow router to connect to normal server (it expects
6390 that normal server always initiates the connection to the router)
6391 so the CONNECT command is only good for connecting to another
6394 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6396 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6397 or some other client was kicked from the channel.
6399 Implemented the handling of the notify type to both client
6402 Implemented silc_server_send_notify_kicked to send the KICKED
6403 notify. It is used to send it to the server's primary router.
6405 * Implemented the KICK command into server and client.
6407 * Added `query' argument to the silc_idlist_get_client function
6408 to indicate whether to query the client from server or not if
6411 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6412 to indicate that the client is not channel founder.
6416 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6418 * Removed the rng context from SilcPacketContext structure and
6419 changed that the packet routine uses the Global RNG API.
6421 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Added support for quit message that client can "leave" on the
6424 channel when it quits the SILC. It is ditributed inside the
6425 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6427 Added silc_server_free_client_data that will take the
6428 signoff message as argument.
6430 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6432 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * Updated parts of the protocol specification to keep it up
6437 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6439 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6440 payloads in one packet.
6442 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6443 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6444 use now the new List flag.
6446 * Also deprecated the following packet types: REPLACE_ID,
6447 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6449 * Added list support for Notify packet in server.
6451 * Added silc_server_send_notify_channel_change to send the
6452 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6453 the silc_server_send_replace_id.
6455 * Added silc_server_send_notify_nick_change to send the
6456 NICK_CHANGE notify type. Deprecates the function
6457 silc_server_send_replace_id.
6459 * Added silc_server_send_notify_join to send the JOIN notify type.
6460 Deprecates the function silc_server_send_new_channel_user.
6462 * Added silc_server_send_notify_leave to send LEAVE notify type.
6463 Deprecates the function silc_server_send_remove_channel_user.
6465 * Added silc_server_send_notify_cmode and
6466 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6467 types. Deprecates the silc_server_send_set_mode function.
6469 * Added SERVER_SIGNOFF notify type to indicate that server has
6470 quit. This means that all clients on the channel from that
6471 server will drop. This can be also used when netsplit happens.
6473 Deprecated REMOVE_ID packet type since it is not needed anymore
6476 Added silc_server_send_notify_server_signoff to send the
6477 SERVER_SIGNOFF notify type. Deprecates the function
6478 silc_server_send_remove_id.
6480 Added also silc_server_send_notify_signoff to send the
6481 SIGNOFF notify type.
6483 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6484 SILC protocol from this day on. Changed the protocol
6485 specification as well.
6487 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6488 notify type. It is used between routers to notify about
6489 topic changes on a channel.
6491 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6494 * Partly updated the protocol specification to comply with the
6495 changes now made. It is still though a bit outdated.
6497 * The JOIN notify type now takes one extra argument <Channel ID>.
6498 The packet used to be destined to the channel but now the
6499 JOIN type may be sent as list thus it is impossible to
6500 destine it to any specific channel. By adding this argument
6501 it is again possible.
6503 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * Added CREDITS file. The CHANGES and CREDITS file will appear
6506 in the distribution as well.
6508 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6510 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6511 types in the server's silcd/packet_receive.c.
6513 * Implemented CMODE and CUMODE to work in router environment.
6515 * Fixed minor encoding and decoding buglet from the
6516 lib/silccore/silcmode.c.
6518 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6521 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6523 * Changed all SilcConfigServer* and silc_config_server* to
6524 SilcServerConfig* and silc_server_config*, respectively.
6527 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6529 * Associated the ID (client or server ID) to the Authentication
6530 Payload to avoid any possibility of forging. Updated the
6531 protocol specification and the code accordingly.
6533 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6535 * The RSA key length is now save to the RsaKey context in the
6536 key generation process in lib/silccrypt/rsa.c. The key length
6537 is now used to figure out the maximum size of the block allowed
6538 to be encrypted/signed.
6540 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6541 is equivalent to the silc_mp_mp2bin but does not allocate any
6544 * Changed silc_mp_mp2bin API to take length argument. If it is
6545 non-zero then the buffer is allocated that large. If zero, then
6546 the size is approximated using silc_mp_sizeinbase, which however
6549 * Created Global RNG API which is global RNG that application can
6550 initialize. After initializing, any routine anywhere in the
6551 code (including library) can use RNG without allocating a new
6552 RNG object. This was done to allow this sort of use of the
6553 RNG in code that has no chance to allocate RNG object. All
6554 applications currently allocate this and many routines in the
6555 library use this. Affected file lib/silccrypt/silcrng.[ch].
6557 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6558 it to use the Global RNG API.
6560 * Defined Authentication Payload into protocol specification that
6561 is used during SILC session to authenticate entities. It is
6562 used for example by client to authenticate itself to the server
6563 to obtain server operator privileges.
6565 Implemented this payload into the lib/silccore/silcauth.[ch].
6566 Implemented also routines for public key based authentication
6567 as the new protocol specification dictates.
6569 Moved definitions of different authentication methods from
6570 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6572 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6573 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6574 silc_pkcs_verify_with_hash functions into the file
6575 lib/silccrypt/silcpkcs.[ch].
6577 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6579 * The client entry's userinfo pointer must be always valid.
6580 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6581 will fail since it requires the userinfo. Now, the userinfo
6582 is allocated as "" if actual userinfo does not exist. Actually,
6583 it must exist and it is totally Ok to drop client connections
6584 that does not announce the userinfo. However, we will make
6585 this workaround for now.
6587 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6588 to return the remote port by socket.
6590 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6592 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6593 SILC_SERVER_PENDING_EXEC and added an new macro
6594 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6595 data or when error occurs while processing the pending command.
6597 Added new argument `destructor' into silc_server_command_pending
6598 and to the SilcServerCommandPending object. This destructor is
6599 now called after calling the pending callback or if error occurs
6600 immediately. If error occurs the actual pending callback won't
6601 be called at all - only the destructor. The destructor may be
6602 NULL if destructor is not needed.
6604 All this applies for client library code as well. Similar
6605 changes were made there as well for the pending commands.
6607 In the client, the application must now allocate the
6608 SilcClientCommandContext with the silc_client_command_alloc
6611 * Added reference counter to the SilcServerCommandContext. Added
6612 function silc_server_command_alloc and silc_server_command_dup
6615 Same type of functions added to the client library for the same
6618 * Removed the cmd_ident from IDListData away since it is now
6619 global for all connections. It is the command identifier used
6620 in command sending and with pending commands. The affected file
6623 * Added reference counter to the SilcSocketConnection objecet to
6624 indicate the usage count of the object. The object won't be
6625 freed untill the reference counter hits zero. Currently only
6626 server uses this, and client ignores it. The client must be
6627 set to use this too later. The affected files are
6628 lib/silccore/silcsockconn.[ch]. Added also the function
6629 silc_socket_dup to increase the reference counter.
6631 This was mainly added because it is possible that the socket
6632 is removed underneath of pending command or other async
6633 operation. Now it won't be free'd and proper DISCONNECTING
6634 flags, etc. can be set to avoid sending data to connection that
6635 is not valid anymore.
6637 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6638 the connection. After that it sets SILC_SET_DISCONNECTED.
6639 It is, however, possible that the socket data is not still freed.
6640 The silc_server_packet_process now checks that data is not
6641 read or written to connection that is DISCONNECTED. The socket
6642 get's freed when the reference counter hits zero.
6644 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6646 * Changed the client operation API: channel_message operation's
6647 `sender' is now the client entry of the sender, not the nickname
6648 and the `channel' is the channel entry, not the channel name.
6650 In the private_message operation the `sender' is now also the
6651 client entry of the sender not the nickname.
6653 Affected file is lib/silcclient/ops.h and all applications
6654 using the client operations.
6656 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Moved the calling of ops->connect() from connect_to_server_final
6659 into receive_new_id functin since that is the point when the
6660 client is actually allowed to send traffic to network. The
6661 affected file is lib/silcclient/client.c.
6663 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6665 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6666 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6667 (if needs broadcasting) instead of broadcasting the packets one
6668 by one which would make a burst in the network traffic.
6670 * Added `broadcast' argument to the functions in silcd/server.[ch]
6671 silc_server_create_new_channel[_with_id] to indicate whether
6672 to send New Channel packet to primary router.
6674 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Added new function into the silcd/server.[ch] files:
6677 silc_server_create_new_channel_with_id to create new channel with
6678 already existing Channel ID.
6680 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6681 lib/silccore/silcpacket.h. This packet is used t send list of
6682 Set Mode payloads inside one packet. Server uses this to set
6683 the modes for the channels and clients on those channels, that it
6684 announced to the router when it connected to it. The protocol
6685 specification has been updated accordingly.
6687 * The silc_server_new_channel did not handle the packet coming
6688 from normal server as it normally does not send that. However,
6689 when it announces its channels it does send it. Implemented
6690 the support for that.
6692 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6693 into the file lib/silccore/id.h.
6695 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Fixed memory leaks in the functions silc_idlist_del_client,
6698 silc_idlist_del_channel and silc_idlist_del_server in the file
6699 silcd/idlist.c. All of those leaked like a sieve.
6701 * Fixed some small memory leaks in the client's function
6702 silc_client_notify_by_server.
6704 * Added functions into silcd/server.c: silc_server_announce_clients,
6705 silc_server_announce_channels and silc_server_announce_server.
6706 These functions are used by normal and router server to announce
6707 to its primary router about clients, channels and servers (when
6708 router) that we own. This is done after we've connected to the
6711 These functions effectively implements the following packet types:
6712 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6713 and SILC_PACKET_NEW_ID_LIST.
6715 * Added new functions into the silcd/packet_receive.[ch]:
6716 silc_server_new_id_list, silc_server_new_channel_list and
6717 silc_server_new_channel_user_list to handle the incoming
6718 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6720 * Added support of changing Channel ID in the function
6721 silc_server_replace_id. If the server that announces a channel
6722 to the router already exists in the router (with same name but
6723 with different Channel ID), router is responsible to send
6724 Replace ID packet to the server and force the server to change
6725 the Channel ID to the one router has.
6727 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6728 client that the Channel ID has been changed by the router. The
6729 normal server sends this to the client. Client must start using
6730 the new Channel ID as the channel's ID.
6732 Implemented handling of this new type into lib/silcclient/client.c
6733 into the function silc_client_notify_by_server.
6735 * Added new function silc_idlist_replace_channel_id into the files
6736 silcd/idlist.[ch] to replace the Channel ID.
6738 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6740 * Call silc_server_command_identify_check always when processing
6741 the IDENTIFY command in silcd/command.c
6743 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6745 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6746 send keepalive packets. The packet can be sent by clients,
6747 servers and routers.
6749 Added function silc_socket_set_heartbeat into the file
6750 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6751 If not set, the heartbeat is not performed. The actual
6752 heartbeat is implemented in the low level socket connection
6753 library. However, application is responsible of actually
6756 Added silc_server_send_heartbeat to send the actual heartbeat
6757 packet into silcd/packet_send.[ch]. Server now performs
6758 keepalive with all connections.
6760 * Added silc_task_get_first function into lib/silcutil/silctask.c
6761 to return the timeout task with shortest timeout. There was a bug
6762 in task unregistration that caused problems. TODO has been
6763 updated to include that task system must be rewritten.
6765 * The client library will now resolve the client information when
6766 receiving JOIN notify from server for client that we know but
6767 have incomplete information.
6769 * Rewrote parts of silc_server_remove_from_channels and
6770 silc_server_remove_from_one_channel as they did not remove the
6771 channel in some circumstances even though they should've.
6773 * Encryption problem encountered in server:
6775 The LEAVE command used to send the Channel Key packet to the
6776 router immediately after generating it. However, the code
6777 had earlier sent Remove Channel user packet but not immediately,
6778 ie. it was put to queue. The order of packets in the router
6779 was that Channel Key packet was first and Remove Channel User
6780 packet was second, even though they were encrypted in the
6781 reverse order. For this reason, MAC check failed. Now, this
6782 is fixed by not sending the Channel Key packet immediately but
6783 putting it to queue. However, this is more fundamental problem:
6784 packets that are in queue should actually not be encrypted
6785 because packets that are sent immediately gets encrypted
6786 actually with wrong IV (and thus MAC check fails). So, packets
6787 that are in queue should be encrypted when they are sent to
6788 the wire and not when they put to the queue.
6790 However, the problem is that the current system has not been
6791 designed to work that way. Instead, the packet is encrypted
6792 as soon as possible and left to the queue. The queue is then
6793 just purged into wire. There won't be any fixes for this
6794 any time soon. So, the current semantic for packet sending
6797 o If you send packet to remote host and do not force the send
6798 (the packet will be in queue) then all subsequent packets to the
6799 same remote host must also be put to the queue. Only after the
6800 queue has been purged is it safe again to force the packet
6803 o If you send all packets immediately then it safe to send
6804 any of subsequent packets through the queue, however, after
6805 the first packet is put to queue then any subsequent packets
6806 must also be put to the queue.
6808 Follow these rules and everything works fine.
6810 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Added new function silc_server_remove_clients_by_server to
6813 remove all client entries from ID list when the server connection
6814 is lost. In this case it is also important to invalidate all
6815 client entires as they hold the invalid server entry. This
6816 fixes fatal bug when server has lost connection and will reconnect
6819 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Made some sanity checks to silc_server_daemonise like to check
6822 whether the requested user and group actually exists.
6824 * Added sanity check to SKE's silc_ske_responder_finish to check
6825 that the public and private key actually is valid.
6827 * Invalidate the client's nickname when receiving Replace ID
6828 packet and the Client ID is being replaced. This means that the
6829 server will query the nickname if someone needs it (client)
6832 * Sort the ID Cache in client library when the ID Cache data
6833 has changed (needs sorting).
6835 * Do not allow for SILC client to create several connections to
6836 several servers. The client does not support windows right now
6837 and generating multiple connections causes weird behaviour.
6839 Irssi-silc client does support windows and can handle several
6840 connections without problems, see: www.irssi.org and SILC plugin.
6842 * Fixed some places where client was added to the IDList. The
6843 rule of thumb is following (in order to get everything right):
6844 If the client is directly connected local client then the
6845 `connection' argument must be set and `router' argument must be
6846 NULL to silc_idlist_add_client function. If the client is not
6847 directly connected client then the `router' argument must
6848 bet set and the `connection' argument must be NULL to the
6849 silc_idlist_add_client function.
6851 * The funtion silc_server_packet_send_local_channel actually did
6852 not check whether the client was locally connected or not. It
6853 does that now. Fixed a bug related to LEAVE command.
6855 * Fixed Remove Channel User payload parsing bug in server's
6856 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6858 * The server's silc_server_save_channel_key now checks also the
6859 global ID list for the channel as it might not be in the local
6860 list. Fixed a bug related to LEAVE command.
6862 * Is this the end of the [<unknown>] buglet that has been lurking
6863 around for a long time? A little for loop fix in server's
6864 silc_server_command_whois_parse that is used by both IDENTIFY
6865 and WHOIS command. At least, this was a clear bug and a cause
6866 of one type of [<unknown>] buglet.
6868 * WHOIS and IDENTIFY commands call the function
6869 silc_server_command_[whois/identify]_check function even if
6870 we are not router server.
6872 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6874 * Added --with-gmp configuration option. If set the GMP
6875 is always compiled in the SILC source tree. If not set then
6876 it is checked whether the system has the GMP3 installed. If
6877 it has then the GMP won't be compiled (the system's headers
6878 and library is used), if it doesn't have it then the GMP is
6879 compiled in the SILC source tree.
6881 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Changed RSA private exponent generation to what PKCS #1
6884 suggests. We try to find the smallest possible d by doing
6885 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6886 not security fix but optimization.
6888 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Added new config entry [Identity] to fork the server and run
6891 it as specific user and group. A patch from Bostik.
6893 * Imported Dotconf configuration library into lib/dotconf.
6894 This will be used to create the SILC configuration files later.
6895 It will appear in the distsribution after this commit.
6897 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6899 * A big code auditing weekend happening. Auditing code for
6900 obvious mistakes, bugs and errors. Also, removing any code
6903 Removed files for being obsolete:
6905 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6906 inline in the file lib/silcutil/silcbuffer.h)
6908 o lib/silcutil/silcbufutil.c (the header has inline versions)
6910 Changed code to fix possible error conditions:
6912 o The buffer formatting routines now check that the destination
6913 buffer really has enough space to add the data. This applies for
6914 both buffer formatting and unformatting
6915 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6916 unformatting was changed to accomodate following rules:
6917 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6918 sent to the function while XXX_*STRING will not allocate or copy
6919 the data into the buffer. Instead it sets the pointer from the
6920 buffer into the pointer sent as argument (XXX_*STRING used to
6921 require that the pointer must be allocated already). This change
6922 makes this whole thing a bit more consistent and more optimized
6923 (note that the data returned in the unformatting with XXX_*STRING
6924 must not be freed now). The routines return now -1 on error.
6926 o Tried to find all code that use buffer_format and buffer_unformat
6927 and added return value checking to prevent formatting and
6928 especially unformatting errors and possible subsequent fatal
6931 o Changed ske->x and ske->KEY to mallocated pointers in
6932 lib/silcske/silcske.h. Fixed possible data and memory leak.
6934 o Added return value checking to all *_parse* functions. Fixed
6935 many memory leaks as well.
6937 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6938 so that buffer overflows would not happen. All code now also
6939 checks the return value as it can fail.
6941 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6943 * Added reconnection support to server if the normal server looses
6944 its connection to the router (for example if router is rebooted).
6945 The server performs normal reconnection strategy implemented
6946 to the server. Affected file silcd/server.c.
6948 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Added new packet type SILC_PACKET_SET_MODE that is used to
6951 distribute the information about changed modes (for clients,
6952 channels and clients channel modes) to all routers in the
6953 network. Updated the protocol specification accordingly.
6955 Added functions into silcd/packet_send.c and
6956 silcd/packet_receive.c: silc_server_send_set_mode,
6957 silc_server_set_mode.
6959 Added new files silcmode.[ch] into lib/silccore that implements
6960 the encoding and decoding of Set Mode Payload. Added new type
6961 SilcSetModePayload. Moved the definitions of different modes
6962 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6964 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6966 * Oops, a little mistake in server's connection authentication
6967 protocol. The protocol is not ended with FAILURE but with
6968 SUCCESS if the authentication is Ok. :) Affected file is
6971 * Implemented NICK_CHANGE notify handling in server in the file
6972 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6973 the local clients on the channel. After the changing nickname
6974 in router environment snhould work and the [<unknown>] nickname
6975 should appear no more.
6977 The silc_server_replace_id function that receives the Replace ID
6978 payload now sends the NICK_CHANGE notify type also in the file
6979 silcd/packet_receive.c
6981 * Changed WHOIS and IDENTIFY command to support the maximum amount
6982 of arguments defined in protocol specs (3328 arguments). This
6983 fixed a bug that caused problems when there were more than three
6986 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Added extra parameter, command identifier, to the
6989 silc_client_send_command so that explicit command identifier
6992 Changed that ID list routines uses specific command identifier
6993 when sending WHOIS/IDENTIFY requests to the server so that they
6994 can be identified when the reply comes back.
6996 Affected files lib/silcclient/command.[ch],
6997 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6999 * Added `sender' argument to silc_server_packet_send_to_channel
7000 to indicaet the sender who originally sent the packet to us
7001 that we are now re-sending. Ignored if NULL. Affected file
7002 silcd/packet_send.[ch].
7004 * Added some server statistics support in silcd/server_internal.h
7005 SilcServerStatistics structure and around the server code. Also
7006 send some nice statistics information when client is connecting
7009 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7011 * Fixed channel ID decoding in server's JOIN command reply in
7012 silcd/command_reply.c
7014 * Fixed braodcasting of replace ID payload to not to send it if
7015 we are standalone server in silcd/packet_receive.c.
7017 * Fixed all channel message sending routines to not to send
7018 packets to clients that has router set, since they are routed
7019 separately in the same function earlier. Affects file
7020 silcd/packet_send.c and all channel packet sending functions.
7022 * In USERS reply, res_argv[i] are not allocated, the table
7023 is allocated. Thus changed that free the table, not its
7026 * In server's whois_check and identify_check if the client is
7027 locally connected do not send any WHOIS commands - they are not
7030 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7032 * Fixed some minor bugs in client when sending WHOIS command. The
7033 arguments was in wrong order.
7035 * Removed statis function add_to_channel from server in
7036 silcd/command.c that was previously used with the joining but
7039 * Tested USERS command in router environment successfully with two
7040 routers, two servers and two clients.
7042 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Reorganized the USERS command and command reply in client library
7045 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7046 When the command is given by user we register a pending command
7047 callback that will reprocess the command after the reply has been
7048 received from the server. When reprocessing the packet we then
7049 display the information. Thus, the USERS information is displayed
7050 now in the command callback instead of in the command reply
7051 callback. The processing of the command is same as previously
7052 when server has sent the command reply in the JOINing process.
7054 * Added to USERS command in silcd/command_reply.c to join the client,
7055 we didn't use to know about, to the channel after we've created
7056 a client entry for it. Also, for clienet we did know already still
7057 check whether it is on the channel or not and add it if not.
7059 * Removed silc_server_command_join_notify as the function and its
7062 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7064 * Changed the client's pending command handling to the same as the
7065 server's pending command handling. It is also now possible to
7066 execute command reply functions from other command reply
7067 function as the function callbacks for commands and command
7068 replies are one and same. The pending commands are not static
7069 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7070 in client connection context. Thus, pending commands are server
7071 connection specific as it is convenient.
7073 Changed the function silc_client_command_pending and
7074 silc_client_command_pending_del and added new function
7075 silc_client_command_pending_check. Removed the
7076 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7079 * Added cmd_ident, current command identifier, to the client
7080 connection context in lib/silcclient/client.h to keep track on
7081 command identifiers used in command sending. Client's command reply
7082 function handling now supports the mandatory command identifiers.
7084 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7085 funtions in client to fully support pending command callbacks.
7087 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7088 as one of the arguments to the application in the command reply
7091 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7092 before first releasing SILC but came back. Now it is removed again
7093 and should come back nomore. The FORWARDED flag was used only
7094 by the JOINing procedure by forwarding the command packet to router.
7095 Now, the JOINing procedure has been changed to more generic (due
7096 to various router environment issues) and FORWARDED is not needed
7097 anymore for anything. The protocol specification is yet to be
7100 Now, removed silc_server_packet_forward from server and the flag
7101 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7103 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7105 * Renamed NAMES command to USERS command. The NAMES was named that
7106 due to historical reasons. Now it is renamed. Also, rewrote
7107 parts of the USERS command. The nickname list is not sent anymore
7108 by the server. Only Client ID and mode lists are sent in the USERS
7109 command. Changed this also to the protocol specification.
7111 The client now resolves the names and stuff after it receives
7112 the USERS list from the server when joining to the channel.
7114 * WHOIS and IDENTIFY commands has been changed to support multiple
7115 Client ID's per command. One can now search for multiple users
7116 in the network by sending only one WHOIS or IDENTIFY command.
7117 Changed the code and the protocol specifications.
7119 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7120 uses silc_server_command_whois_parse to parse the request. */
7122 * If normal server, do not parse the WHOIS and IDENTIFY requests
7123 before sending it to the router. Saves some time.
7125 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * Fixed JOIN command on client library. Wrong number of arguments
7128 used to crash the client.
7130 * Added silc_server_channel_has_global function to check whether
7131 channel has global users or not.
7133 * Added silc_server_channel_has_local function to check whether channel
7134 has locally connected clients on the channel.
7136 * The silc_server_remove_from_one_channel now checks whether the
7137 channel has global users or not after given client was removed from
7138 the channel. It also checks whether the channel has local clients
7139 on the channel anymore. If it does not have then the channel entry
7140 is removed as it is not needed anymore.
7142 * The silc_server_notify now checks on JOIN notify whether the joining
7143 client is one of locally connected or global. If it is global then
7144 the channel has now global users on the channel and that is marked
7145 to the channel entry. Also, it now saves the global client to
7146 global list who is joining and JOINs it to the channel. This is
7147 for normal server, that is.
7149 Changed silc_server_send_notify_on_channel,
7150 silc_server_packet_relay_to_channel and
7151 silc_server_packet_send_to_channel check if we are normal server
7152 and client has router set (ie. global client) do not send the
7153 message to that client, as it is already routed to our router.
7155 * Implemented LEAVE notify type handling in silc_server_notify
7158 * Tested LEAVE command in router environment successfully. Tested
7159 with two routers, two servers and two clients.
7163 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7165 * Implemented SIGNOFF notify type handling in silc_server_notify
7168 * silc_server_remove_id now removes the client entry from all channels
7169 it has joined and thusly sends SIGNOFF notify type.
7171 * Rewrote the NAMES list generation in server by removing two excess
7172 loops. The lists are created now inside one loop.
7174 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7176 * silc_server_remove_channel_user checks now also global list
7177 for channel and client.
7179 * silc_server_new_channel_user checks now both local and global
7180 list for channel and client. Fixed a bug in client id decoding.
7181 Used to decode wrong buffer.
7183 * silc_server_channel_message checks now both local and global
7184 list for channel entry.
7186 * Tested channel joining (hence JOIN) in router environment
7187 successfully. Tested with two routers, two servers and two
7190 * Tested channel message sending in router environment successfully.
7192 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Added silc_server_save_channel_key into server.[ch] to save the
7195 received channel key in Channel Key payload processing. It is
7196 also used in JOIN command reply handling.
7198 Equivalent function silc_client_save_channel_key added into
7199 client.[ch] into client library.
7201 * Changed JOIN command reply to send information whether the channel
7202 was created or not (is existing already) and the channel key
7203 payload. Changed protocol specs accordingly.
7205 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7206 the request was sent by ID and not by nickname. Crashed on
7209 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7211 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7212 now correctly save the received data.
7214 * silc_server_free_sock_user_data now notifies routers in the
7215 network about entities leaving the network.
7217 At the same time implemented functions silc_server_remove_id
7218 and silc_server_send_remove_id to receive and send REMOVE_ID
7219 packets. The packet is used to notify routers in the network
7220 about leaving entities. The ID removed will become invalid in
7223 * Added function silc_idlist_del_server into server. Removes and
7224 free's server entry from ID list.
7226 * silc_server_private_message function now checks, if we are router,
7227 that the destination ID really is valid ID, naturally.
7229 * In router when NEW_ID packet is received (for new client) the
7230 hash of the Client ID is saved in the ID Cache but the
7231 client->nickname is set to NULL, instead of putting the hash
7234 IDENTIFY command now also checks that client->nickname must be
7235 valid. If it is not if will request the data from the server who
7236 owns the client. Added new function
7237 silc_server_command_identify_check.
7239 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7240 to set the command to already allocated Command Payload.
7242 * Tested private message sending in router environment with two
7243 routers, two servers and two clients. Fixed minor bugs and now
7246 * Fixed segfault from client's NAMES command. Used to crash if
7249 * Forwarded packets must not be routed even if it is not destined
7250 to the receiver. Changed server code comply with this.
7252 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7254 * Added `require_reverse_mapping' boolean value to ServerParams
7255 structure. If TRUE (not default) the server will require that
7256 the connecting host has fully qualified domain name.
7258 If the reverse mapping is not required and hostname could not be
7259 found the IP address is used as hostname.
7261 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7263 * Implemented version string checking to both client and server.
7264 The check is incomplete currently due to the abnormal version
7265 strings used in development version of SILC.
7267 * Changed all command functions in server to use the new
7270 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7272 * Changed char *data to unsigned char *data in ID Cache system to
7273 support binary data as ID Cache data. Changed code to support
7274 binary data in lib/silccore/idcache.c.
7276 * Renamed silc_server_packet_relay_command_reply to
7277 silc_server_command_reply as it is normal packet receiving
7278 function. Rewrote the function to accept command replys for
7279 servers and not only for clients.
7281 * Mark remote router always as registered server if we are connecting
7282 to it. Otherwise, commands sent by the router to us are ignored.
7284 * All ID List find routines now returns the ID Cache Entry pointer
7285 as well if requested.
7287 * WHOIS command works now in router environment, tested with two
7288 routers, two servers and two clients.
7290 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7291 in router environment (as it is almost equivalent to WHOIS) but
7292 hasn't been tested thoroughly. Added new functions:
7294 silc_server_command_identify_parse
7295 silc_server_command_identify_send_reply
7296 silc_server_command_identify_from_client
7297 silc_server_command_identify_from_server
7299 * Disabled route cache adding because adding two different ID's with
7300 same IP replaces the old cache entry thus giving wrong route.
7301 The entry->router->connection is always the fastest route anyway
7302 so route cache may not be needed. Of course, new routes maybe
7303 established after receiving the ID when the entry->router->connection
7304 might not be anymore the most optimal.
7306 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7308 * Add route cache for received ID for fast routing.
7310 * Added silc_server_packet_route to route received packet on router
7311 that is not destined to us.
7313 * Renamed silc_server_get_route to silc_server_route_get.
7315 * Added id_string and id_string_len fields into SilcServer to
7316 include encoded ServerID for fast comparing without excess
7317 encoding of the ID's.
7319 * Cleaned up WHOIS command on server side. Added following static
7322 silc_server_command_whois_parse
7323 silc_server_command_whois_check
7324 silc_server_command_whois_send_reply
7325 silc_server_command_whois_from_client
7326 silc_server_command_whois_from_server
7328 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7329 arguments in command replies. All command functions should be
7330 updated to use this macro.
7332 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7334 * Minor typo fixes on command reply handling on server.
7336 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7338 * Added silc_server_command_add_to_channel internal routine to add
7339 the client to the channel after router has created the channel and
7340 sent command reply to the server.
7342 * Added generic silc_server_send_command to send any command from
7345 * Use static buffer with ID rendering instead of duplicating data.
7347 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7349 * Fixed a channel user mode bug when joining to a channel server gave
7350 everybody channel founder rights, oops.
7352 * We mark ourselves as the router of the incoming server connection
7353 if we are router ourselves. This way we can check in some packet
7354 sending functions whether it is locally connected server. For
7355 incoming router connections we put NULL.
7357 * For router sending packets locally means now always sending the
7358 packet cell wide; to local clients and local servers. For normal
7359 server sending packet locally means sending it to only local
7362 * Fixed the JOIN command to really work in router environment. If the
7363 channel is created it is always created by the router. Router is
7364 also responsible of making the initial joining to the channel,
7365 sending JOIN notify to the sending server and distributing
7366 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7367 does not exist server doesn't do anything else but forward the
7368 command to the router which performs everything.
7370 * Added silc_server_send_channel_key function to send the Channel Key
7373 * Added silc_server_create_channel_key to create new channel key. The
7374 channel key is now re-generated everytime someone joins or leaves
7375 a channel, as protocol dictates. Note: channel->key_len is the
7378 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7381 packet_receive.[ch] to separate packet sending and receiving
7382 routines. The server.[ch] now includes everything else including
7383 actual packet processing (writing and reading data) and other
7386 Renamed silc_server_private_message_send_internal to
7387 silc_server_send_private_message. The routine is still though
7388 used only to relay private messages as server does not send
7389 private messages itself.
7391 Renamed silc_server_new_channel to silc_server_create_new_channel
7392 and added new function sicl_server_new_channel that handles the
7393 incoming New Channel packet. Added also new sending function
7394 silc_server_send_new_channel to send New Channel Payload.
7396 * Added new function silc_server_notify to process incoming notify
7397 packet to the server/router. Server may then relay the notify
7398 to clients if needed.
7400 * Added new function silc_server_new_channel_user to process incoming
7401 New Channel User packet. Router will redistribute the packet and
7402 send JOIN notify to its local clients and locally connected servers
7403 if needed. Normal server will send JOIN notify to its local client
7404 on same channel when received this packet. Added also corresponding
7405 sending function silc_server_send_new_channel_user to sent the
7408 * Added boolean route argument to send_notif_to_channel and
7409 packet_send_to_channel functions to attempt to route the packet
7410 if it is TRUE and send only locally if it is FALSE.
7412 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7414 * silc_server_replace_id now broadcasts the received replace ID
7415 packet if it is not broadcast packet already. The router must
7416 broadcast to inform other routers about changed ID.
7418 * Added backpointer to server's router into SilcServer context in
7419 silcd/server_internal.h.
7421 * Fixed silc_server_packet_broadcast to send correct broadcast
7424 * The channel key is now distributed to the local client as soon
7425 as it is received from the router (in router environment) so that
7426 no other packet may be sent for the channel until client has
7429 * silc_server_remove_channel_user now broadcasts the received
7430 Remove Channel User packet if it is not broadcast packet already.
7431 The router must broadcast to inform other routers about removed
7434 * Added users field into SilcPacketContext that is a reference count
7435 of the context. One can increase the reference count by calling
7436 silc_packet_context_dup which is now changed to just increase the
7437 reference count instead of duplicating the data. The reference
7438 count is decresed by calling silc_packet_context_free that will
7439 free the data after the reference count hits zero.
7441 For now on the packet context and everything allocated into it
7442 (including the raw packet from network) must be freed by calling
7443 the new silc_packet_context_free function. Added also new function
7444 silc_packet_context_alloc that must be used now to allocate the
7445 context. This also means that if a routine is asynchronous from
7446 silc_[client/server]_packet_parse_type the packet context must
7447 be duplicated by calling silc_packet_context_dup. Otherwise it
7448 gets free'd after silc_[client/server]_packet_parse_type returns.
7449 Also, one must remember that if packet is duplicated then its
7450 reference count must be decresed by calling the free function as
7451 many times as it was duplicated.
7453 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7454 from both client and server.
7456 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7458 * Made joining to a channel working in router environment.
7460 * Cleaned up JOIN command on server side and create function
7461 silc_server_command_join_channel internal routine to make the
7464 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7466 * Changed silc_command_pending list to SilcDList. Also, added
7467 `ident' field to SilcServerCommandPending structure to identify
7468 the reply and to call correct callback.
7470 Added silc_server_command_pending_check function to replace the
7471 corresnponding macro. The silc_command_pending list is not
7474 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7475 to set identifier to previously allocated Command Payload. It
7476 is used to set identifier for command when resending Command
7479 * Added silc_command_payload_encode_payload to encode Command
7480 Payload buffer from SilcCommandPayload structure.
7482 * Added silc_argument_payload_encode_payload to encode Argument
7483 payload buffer from SilcArgumentPayload structure.
7485 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7487 * Changed WHOIS command to support router connection on server side.
7488 The whois request is always sent to router unless the server is
7489 standalone server. After server has received the reply from the
7490 router will it send the reply to the client.
7492 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7493 broadcast received broadcast packet. The function is used only
7494 by router. The broadcast packet is always sent to the router's
7497 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7498 render given ID to printable string, for log files for example.
7500 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7502 * Made basic router to router connections working. At least they
7503 can now connect to each other but nothing really works the way
7504 they are supposed - yet.
7506 * Added new initiator token to RouterConnection configuration
7507 file in silcd/serverconfig.[ch]. It is used to tell whether we
7508 are the initiator to the remote router or whether we'll expect
7509 the other end to connect.
7511 * Moved registering of listener task to silc_server_init, hence
7512 the server starts listenning as soon as it is run, even if it
7513 does not have connections to other routers. Let's see how well
7516 * Changed default connection retry timeouts for more suitable in
7519 * Removed cipher and such arguments from silc_idlist_add_client
7520 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7521 Added new function silc_idlist_add_data to add the keys and stuff
7524 * Added SilcIDListData structure and added it to SilcClientEntry
7525 and SilcServerEntry as their first field in the structure. This
7526 way we can explicitly cast the ID entries to the SilcIDListData
7527 structure and get common data for the entries. In past, we had
7528 to first check what type of connection it is and then cast it to
7529 correct ID entry type. Now, we can directly cast the opaque
7530 pointer to the SilcIDListData (no matter what ID entry it actually
7531 is) and get the data needed.
7533 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7535 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7536 in some circumstances even if threre were timeout tasks, though not
7537 IO tasks, but tasks anyway. Now fixed.
7539 * Defined SilcServerConnection structure to hold connection specific
7540 stuff about directly connected servers and routers. The definition
7541 is currently in silcd/server_internal.h. I thought about having
7542 a bit more important role fro this struct but for now it is used
7543 only when connecting to other server (or router actually).
7545 * Added connecting retry support in server when connecting to
7546 router(s). The retry feature implement exponential backoff
7547 algorithm. Also, added SilcServerParams structure to hold default
7548 parameters for server. For now, it include these retry settings
7549 and are hard coded. After server is moded to be as Silc Server
7550 Library this structure will be more important.
7552 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7554 * Changed client librarys channel->clients table to SilcList and
7555 changed code accordingly.
7557 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7559 * Changed client's channel table to SilcList and changed code
7560 accordingly. Also changed SilcChannelClientEntry to include back-
7561 pointer to the channel so that client entry can use that structure
7562 as list as well and we have fast cross-reference to the channel.
7563 This change dramatically decreased the complexity of channel
7564 handling with client entry and vice versa (removed one extra
7565 loop when searching for channel entry from many functions).
7567 * Changed server->sim from table to SilcDList and changed code
7570 * NAMES command can now be used from user interface. It will show
7571 the user list on the channel, neatly.
7573 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7574 Code now saves realname of the user if it becomes available.
7576 * Renamed configure.in to configure.in.pre and made ./prepare
7577 script to automatically add correct version string to
7578 configure.in which it creates from configure.in.pre.
7580 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7582 * NAMES command reply now shows users mode with the nickname when
7585 * Moved silc_client_ch[u]mode[_char] functions from
7586 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7587 place sucks, they are utility functions and should be in some
7590 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7592 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7595 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7599 * Added TRQ (efficient deque and list library) into lib/trq. This is
7600 a very good list library that is currently used in the SILC. Defined
7601 SilcList API over the library because I didn't like the API very
7602 much. See lib/trq/silclist.h for the API and examples of how to
7603 use the API. Fixed various places in the code to use the new
7604 SilcList API. The SilcList is meant for lists that has a structure
7605 already defined as a list. It is not suitable to add just some
7606 context to the list (in TRQ, the context is the list actually).
7608 So, I defined SilcDList that can be used for the purpose where
7609 predefined list structure does not exit. This can be used as
7610 such list. Now some context just can be added to the SilcDList.
7611 Currently this list is not used in the SILC just yet, though there
7612 are a lot places where this can replace dynamically allocated
7613 tables and I will fix these places, later, to use SilcDList.
7614 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7615 and use TRQ internally).
7617 Also fixed some annoying warning messages that the original TRQ
7618 code generated. Also minor changes to TRQ's Makefile.in.
7620 * Added support for querying by Client ID to both WHOIS and
7621 IDENTIFY commands into server, as required by the protocol.
7623 * Removed method function pointers from SilcBuffer structure. They
7624 weren't used to anything and just increased the context size for
7625 no good reason. This change also made silc_buffer_alloc and
7626 silc_buffer_free functions inline functions.
7628 * Disabled command flooding detection support until it's fixed so
7629 that it accepts commands in but does not execute them more than once
7632 * Added silc_net_localhost(), to return local hostname, into
7633 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7634 that must be initialized before calling silc_client_init.
7636 * Added new function: silc_server_send_notify_on_channels to send
7637 notify messages to all channels client has joined. It is assured
7638 that the message is sent only once per client.
7640 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7641 lib/silcutil/silcutil.[ch] as silc_format function. The new
7642 function is generic and is used by server as well, not only by
7643 the logging routines.
7645 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7646 the provided version string was not acceptable. Added new function:
7647 silc_ske_check_version into lib/silcske/silcske.h. The function
7648 must be implemented by the application (client or server) and it
7649 does not reside in the SKE library. The function checks the version
7650 string remote end sent.
7652 * Added back pointers (to opaque context and to SilcSocketConnection)
7653 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7655 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7656 duplicate packet context structure.
7658 * Changed `notify' client operation to send same arguments as client
7659 receives from server except for ID's. ID's are mapped to correct
7660 ID entry and that is returned. Also, if channel entry is not sent
7661 by server but the notify is for channel the channel entry is sent
7662 to application (otherwise application doesn't know that it is for
7663 channel (library gets it from packet's Destination ID)).
7665 * Added silc_client_remove_from_channels into client library to
7666 remove a client from all channels it has joined to. Used when
7667 received SIGNOFF notify from server. Added also new function
7668 silc_client_replace_from_channels to replace old ID entry with
7669 new ID entry on all channels. Used when received NICK_CHANGE
7672 * Fixed ID Cache list handling in silc_idlist_get_client in
7673 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7674 to get (or query) client by ID.
7676 * Updated TODO list.
7678 * Added connection authentication status message defined by the
7679 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7680 support for these into the code in client and server side.
7682 * Added generic function silc_client_send_command to send any command
7683 with variable argument list. Application should use this function
7684 to send commands if the command functions provided by the library
7685 does not suite for the application's user interface needs.
7687 * Added new `failure' client operation. Application is notified about
7688 received failure packet if client is executing a protocol. In this
7689 case the protocol's execution has failed.
7691 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7692 is required by the protocol.
7694 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7695 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7698 * Added status flag to SilcSKE object to indicate realtime status
7699 of the SKE protocol.
7701 * Application receives now exactly same command reply arguments as
7702 the library receives from server. However, if ID is received the
7703 corresponding ID entry is returned to the application (eg. Client
7704 ID is mapped to correct SilcClientEntry entry and that is returned).
7705 Changed command_reply client operation due to this change.
7707 * Changed all ID's in commands and in command replys as ID Payloads.
7708 Change affected both client and server side codes.
7710 All ID's sent in SILC network (with execption of ID's in SILC
7711 Packet header) are sent in ID Payload to support variable length
7714 * Server now notifies nick changes and notifies all clients on
7715 the channels about the new nickname (about the new Client ID,
7718 * Implemented CMODE command to change channel modes. Supports all
7719 channel modes defined by the protocol specs except ban and invite
7720 lists. (Also, private channel key mode is supported but support for
7721 setting private channel key in client is missing, thus, this mode
7722 has no effect on client side (except that server requires that the
7723 client uses private channel key and normal channel traffic does not
7726 Also, invite mode works per se, but INVITE command does not work
7727 yet correctly, so you can set channel as invite only channel but
7728 inviting clients to the channel does not work (it is yet to be
7729 thought what's the best way to do it).
7731 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7732 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7733 Implemented CUMODE command to change user's mode on the channel.
7734 Supports all modes defined by the protocol specs.
7736 * Added NAMES command reply to return users modes on the channel.
7738 * Removed unnecessary and slow ciphers from lib/silccrypt.
7740 * Set SO_KEEPALIVE option to connection sockets by default.
7742 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7744 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7745 redefined the Notify Payload into protocol specs.
7747 * Added silc_id_payload_parse_id to get ID directly from raw
7750 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7752 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7753 accept searching by Client ID as well.
7755 * Added support for LEAVE and SIGNOFF notify types in client library.
7757 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7758 to parse ID Payload from raw data.
7760 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7762 * Added flags parameter into silc_ske_assemble_security_properties
7763 function in lib/silcske/silcske.[ch].
7765 * Changed notify client operation to fit better for notify messages
7766 sent by server. The notify payload received from server is now
7767 passed to the application (after parsing it to SilcNotifyPayload).
7768 It is application's responsibility to retrieve the arguments
7769 from the payload and show the message the way it wants. The message
7770 sent by server is implementation specific.
7772 * Changed public keys to comply with the protocol specification.
7773 Old public keys are not supported anymore and are not compatible.
7775 * Removed nickname from Channel Payload as the latest draft removed
7776 it. The client must resolve the nickname from the NAMES command
7777 reply received when it joined the channel.
7779 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7781 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7783 * Fixed some errors in protocol specification drafts.
7785 * Created lib/silccore/silcnotify.c to implement Notify Payload
7786 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7787 generic payloads described by protocol specifications. The file
7788 includes implementations for ID Payload and Argument Payload.
7790 * Changed Command Payload implementation to use the new Argument
7791 Payload. Changed command_xxxx_payload to command_payload_xxxx
7792 to comply with SILC coding conventions.
7794 * Added suppport for Argument Payload handling in Notify Payload
7795 implementation as protocol requires it. Added the new support
7796 into server and client lib as well.
7798 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7800 * Added support for multiple nicknames on same channel. [n] is
7801 added locally to the nickname if there are more than one same
7802 nicknames on the channel.
7804 * Server now sends all nicknames that matched WHOIS request.
7805 Client also shows the list received from server.
7807 * Added TOPIC command to client side. User can now set and show
7808 current topic on channel.
7810 * Added MOTD command to client and server. Also, server sends the
7811 motd when client connects to the server.
7813 * Changed version strings to comply ISO 8601.
7815 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7817 * Fixed protocol error handling in client library. It should now
7818 cope even if the SKE fails for some reason.
7820 * Made new protocol specification drafts for submitting to IETF.
7822 * Implemented TOPIC command to server in silcd/command.c.
7824 * Added two new notify types into lib/silccore/silcnotify.h:
7825 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7826 notify nickname change and topic setting/change on a channel.
7828 * API change of command_reply operation in client library. The
7829 application gets now the status type received from server as well.
7831 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7833 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7835 * Cras fixed and optimized the packet handling even further and
7836 it should work now. Minor change to the prototype of function
7837 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7839 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7841 * Added new function into lib/silcutil/silcschedule.[ch]:
7842 silc_schedule_with_fd to select() a specified fd. The function
7843 returns after timeout expires or data arrives or goes. The
7844 function is used by packet routines to wait that all data is
7845 received from network.
7847 * Fixed data reading from network in lib/silccore/silcpacket.c.
7848 The code now assures that all data is read from the fd and then
7849 continues packet processing. This was a bug fix since the code
7850 used to drop some data in some circumstances.
7852 * Added new function into lib/silcclient/client.[ch]:
7853 silc_client_start_key_exchange to start key exchange after
7854 connection has been established to server. The code internally
7855 now uses this funtion but its main purpose was to provide it
7856 for applications that perform their own connecting. After
7857 application has created a connection it merely calls this
7858 function to start the key exchange between client and server.
7859 The library takes care of everything else after that.
7861 Updated also lib/silcclient/README to explain the usage of
7864 * Do not send to application information that connection has
7865 been established. Application gets notified it by connect
7868 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7870 * Applied cras's patch to add silc_schedule_one function. The
7871 function runs scheduler once and returns.
7873 * Fixed the scheduler after cras messed it up. The timeout
7874 handling works now as it's supposed to work.
7876 * Added into lib/silccore/ silcnotify.h to include notify
7877 message types support. Changed silc_server_send_notify*
7878 functions, in server.[ch], to support those new notify types.
7879 Added the support for the notify types into client library,
7880 as well. Added new notify client operation into ops.h in
7883 * Changed silc_server_packet_send_to_channel to send normal
7884 packets instead of just channel message packets. The function
7885 is now used to send the notify packets to channels. It is not
7886 used to send channel message packets anymore, as server never
7889 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7890 va_arg()s as it seems to require it nowadays. I guess, if SILC
7891 is compiled with older va_arg() the new code should work anyway.
7893 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7895 * Splitted core library. Core library (lib/silccore) includes
7896 now only SILC protocol specific core (and common) components.
7897 Created new utility library (lib/silcutil) that includes more
7898 generic purpose stuff. The stuff for util library was taken
7899 from the old core library. This was minor and easy split.
7901 * Created SILC Client Library (lib/silcclient) that includes
7902 implementation of the SILC client without user interface. This
7903 was major move from silc/ directory. The code has been changed
7904 so that it is transparent towards the user interface. The
7905 silc/ directory includes now the same user interface as before
7906 and it uses the new client library. Read lib/silcclient/README.
7907 Basicly, the client library performs everything else related
7908 to SILC except user interface handling. Also, configuration
7909 files are considered to be part of user interface and library
7910 does not handle them.
7912 This change also changed a lot of structures, function naming etc.
7913 Most important change was that SilcClientWindow object was
7914 renamed to SilcClientConnection in the client library. Created
7915 also new file lib/silcclient/ops.h. Also added new files
7916 silc/local_command.[ch] and silc/client_ops.[ch].
7918 All these changes were made to make it easier for user interface
7919 designers to create what ever user interface for the SILC client
7922 It is also expected that the server will be moved to lib
7923 directory as well and SILC Server Library will be created;
7924 sometimes in the future.
7926 * Removed Local commands from lib/silccore/silccommand.h as
7927 they are application specific and new client library does not
7928 handle any of those anymore.
7930 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7931 old client implementation in silc/.
7933 * Added support for callback functions in SILC_LOG_* macros.
7934 Application can now set its own callbacks that will be called
7935 instead of using the default functions that will always print
7936 the debug messages to stderr (or stdout). Also, debugging can
7937 now be disabled by setting silc_debug to FALSE and re-enabled by
7938 setting it to TRUE. Note, that logging will still work even
7939 if debugging is disabled.
7941 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7942 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7943 silc_log_reset_debug_callbacks.
7945 * To enable debugging in silc client one must give now -d
7946 option on command line.
7948 * Changed silc_schedule_init to automatically allocate task queues
7949 if they are not allocated before calling it.
7951 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7953 * Added GMP 3.1 into math library.
7955 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7957 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7958 a channel in SILC network. The packet is used by servers and
7959 routers to notify other routers that user has left a channel.
7960 This little feature was missing until now. Added the feature
7961 to protocol specification as well.
7963 Added functions: silc_server_send_remove_channel_user and
7964 silc_server_remove_channel_user into server.[ch].
7966 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7967 lib/silccore/silcpacket.h. However, they are not implemented
7970 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7972 * Fixed joining to a channel and sending channel messages
7973 between server and router. The channel message sending should
7974 now work inside a cell.
7976 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7978 * Fixed the private message sending between server and router.
7979 The private message sending should now work inside a cell.
7981 * Added silc_server_replace_id into server.[ch] to replace
7982 existing ID in the SILC network.
7984 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7985 and silc_idlist_replace_server_id into idlist.[ch] in server.
7987 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7989 * Fixed the server to server connections. Server can again now
7990 connect to router. Router to router connections probably does
7993 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7995 * Added dynamic protocol registering support. Now protocols can
7996 registered and unregistered on the fly. Patch by cras.
7998 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8000 * Added lib/contrib directory to hold routines that some platforms
8001 don't have but are needed by SILC.
8003 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8004 into lin/contrib to provide getopt() and getopt_long() for
8005 those who don't have it.
8007 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8009 * Added AWAY command to client. When away message is set and
8010 client receives a private message packet the client automatically
8011 replies to the sender with the away message.
8013 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8014 bug seemed to be the cause of recent problems when compiling
8017 * Added version detection support to SKE protocol specification
8018 and added the new changes to the SKE implementation as well.
8019 There were other minor changes in the SKE protocol as well.
8021 Many changes in lib/silcske/silcske.[ch] and in
8022 lib/silcske/payload.[ch].
8024 * Added ^U functionality, clear input line. Patch from cras.
8026 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8028 * Mainly small bugfixes on core library. Fixed some debugging
8029 logging and buffer overflow in silclog.c.
8031 * Updated config.sub and config.guess on the distribution tree.
8033 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8035 * Added command lagging support in server. Client may execute
8036 commands now only once in two seconds.
8038 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8040 * Optimized packet reception. MAC computation and checking is now
8041 also more optimized. A lot previously duplicated code is now
8042 used as generic by both client and server.
8044 * Fixed key pair generation in clientutil.c
8046 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8048 * Added into lib/silccore/silcbufutil.[ch] new function;
8049 silc_buffer_realloc.
8051 * Moved generic packet sending/encryption functions to
8052 lib/silccore/silcpacket.[ch] from client and server. Some
8053 rewriting of the functions.
8055 * Moved all generic packet reception/decryption functions to
8056 lib/silccore/silcpacket.[ch] from client and server. The
8057 packet processing is now much cleaner in both client and server.
8058 These were major changes in both client and server.
8060 * Created many common functions in server to do packet sending.
8061 Previously code were duplicated a lot, this has been removed
8064 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8066 * Rewrote major parts of the ID cache system. Don't know
8067 whether it is better now or not but at least the API is more
8070 * Major rewrite on ID cache stuff on client because of the ID
8071 cache API changes. Added idlist.c to client.
8073 * Also major rewrite on ID cache stuff on server as well.
8074 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8075 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8076 in hand, instead they are all put into the ID cache system now.
8077 All server_idlist_* routines uses ID cache now instead of
8078 traversing its own lists (those lists does not exist anymore).
8079 SilcIDList though still exists. Also, SilcXXXEntry's are
8082 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8084 * Finally made the SKE implementation compliant to the protocol
8085 specification. All mp integers are now binary encoded as
8086 opposed being HEX encoded.
8088 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8091 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8092 functions: silc_[encode/decode]_pem. Also added function
8093 silc_encode_pem_file to PEM encode with newlines ('\n') for
8096 * SILC public keys are now encoded either PEM or binary. Same
8097 option is for private keys as well. By default private keys
8098 are binary encoded and public keys PEM encoded. Silly HEX
8099 encoding were removed.
8101 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8102 function to create fingerprints.
8104 * Fixed a bug in SHA1; does not change the original data anymore.
8106 * Partly implemented INFO command on client and server side.
8107 Fixed CLEAR command. Changes to SERVER command; show current
8108 server(s) when giving command without arguments. Added
8109 VERSION command to client.
8111 * Added check to server that unregistered connections cannot
8112 execute commands (unless it is specificly allowed).
8114 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8116 * Fixed screen refresh.
8118 * Fixed channel joining bug from client. On some circumstances
8119 client tried to join to a channel it had already joined.
8121 * Added public key verification process into client's protocol.c.
8122 The client now verifies the public key from user and saves
8123 it into ~./silc/serverkeys/ directory.
8125 Added into: clientutil.[ch]: silc_client_verify_server_key.
8127 * Changed SKE protocol's silc_ske_initiator_finish function
8128 to accept callback function that verifies the received public
8129 key. Removed old silc_ske_verify_public_key function.
8131 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8133 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8134 silc_pkcs_private_key[_data]_set.
8136 * Made the password and public authentication more cleaner in
8137 server's protocol.c.
8139 * Removed historic and obsolete protocol `channel_auth' from
8140 both client and server.
8142 * Removed wrong way of sending command status messages from
8143 server to client in server's command.c. The old way violated
8144 protocol specification.
8146 Changes to silccore/silccommand.[ch]: removed
8147 silc_command_encode_status_payload -> not needed anymore,
8148 changed silc_command_encode_payload_va to accept extra
8149 argument on variable argument list. The argument type must
8150 now be provided to the function. Also, added new function:
8151 silc_command_encode_reply_payload_va which is same as
8152 normal command_encode_payload_va except command status type
8153 is provided as extra argument.
8155 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8157 * Added ~./silc directory handling. The directory includes the
8158 public and private keys for the client.
8160 Added silc_client_check_silc_dir, silc_client_create_identifier
8161 and silc_client_load_keys.
8163 * Implemented SILC protocol compliant public key. Added public
8164 and private key saving to and loading from files.
8166 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8167 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8168 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8169 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8170 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8172 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8173 silc_pkcs_load_[public/private]_key.
8175 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8177 * Added silc_server_get_route (route.[ch]) to get connection
8178 data for the fastest route for given ID.
8180 * Implemented INVITE command on client and server. The command
8181 were re-defined in the SILC Protocol Specification and the
8182 implementation now complies with the specification.
8184 * Implemented PING command on client and server.
8186 * Implemented NAMES command on client and server. The server side
8187 supports currently only normal server not router server yet.
8188 Some changes to NAMES definition in SILC protocol specification.
8190 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8192 * Implemented LEAVE command on client and server.
8194 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8195 again. This change was made to the protocol as well. Server
8196 should not violate the protocol specification anymore.
8198 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8200 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8201 was tested. SOCKS4 was not but should work anyway.
