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

80 options to the server. Affected files silcd/serverconfig.[ch],
81 silcd/command.c and silcd/packet_receive.c.
83 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
85 * Added resolve_cmd_ident field to the SilcClientEntry structure
86 too so that if the entry is for example being resolved so
87 another command may attach to the same pending command reply
88 without requiring to resolve the same entry again. Added
89 support for adding multiple pending commands for one
90 command idenfier. Affected files lib/silcclient/command.[ch],
91 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
93 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
95 * Defined that server receives WHOIS command reply for private
96 and secret channels too. Updated protocol specs and the
97 code in server. Affected file silcd/command.c.
99 * Defined <channel user mode list> argument to WHOIS command
100 reply for returning user modes on the channels. The
101 channel list now doesn't include the user mode anymore but the
102 actual channel mode. Updated protocol specs and the code in
103 client and server. Affected files are silcd/command_reply.c,
104 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
105 and lib/silcclient/command_reply.c.
107 * Save the channels list in WHOIS command reply in normal server
108 so that WHOIS always shows joined channels also in normal
109 server and not just on router. Affected file is
110 silcd/command_reply.c.
112 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
114 * Defined that server receives USERS command reply for private
115 and secret channels too. Updated protocol specs and the
116 code in server. Affected file silcd/command.c.
118 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
120 * Changed the UMODE's mode mask argument to be optional. If
121 not provided then the command merely returns the current mode
122 mask to the client. Updated protocol specs and the server.
123 Affected file is silcd/command.c.
125 * Added SILC session detachment/resuming support. It is possible
126 to detach by closing the network connection and then re-connect
127 and resume to the old client session. Added DETACHED user
128 mode that server will set for detached client. Added new
129 packet RESUME_CLIENT which is used to perform the resuming
130 process. Added DETACH command. Updated the protocol specs,
131 core library, client and server. Protocol TODO #22. Very
132 many affected files around the tree.
134 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
136 * Changed the CMODE's mode mask argument to be optional. If
137 not provided then the command merely returns the current mode
138 mask to the client. Updated protocol specs and the server.
139 Affected file is silcd/command.c.
141 * Changed the Killer's Client ID in KILLED notify to be just
142 any ID payload since router server is allowed to kill as well.
143 Updated protocol specs, client libary and server. Affected
144 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
145 and irssi/src/silc/core/client_ops.c.
147 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
149 * Added new user modes ANONYMOUS for special anonymous servers
150 that may set the mode for client, and BLOCK_PRIVMSG which
151 client may set to block incoming private messages unless the
152 Private Message Key flag is set (using private keys to protect
153 private messages). Updated protocol specs and code in client
154 and server and core library. Protocol TODO #23. Affected
155 files are lib/silccore/silcmode.h, silcd/server.[ch],
156 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
157 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
159 * Added new channel user mode BLOCK_MESSAGES which the client
160 may set to itself to tell server not send channel messages.
161 Other packets such as channel key packets are still sent.
162 Protocol TODO #23. Updated the protocol specs, client and
163 server. Affected files are lib/silccore/silcmode.h,
164 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
165 lib/silcutil/silcutil.c, silcd/command.c, and
168 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
170 * Redefined the Status Payload to include now two 8 bit fields,
171 instead of one 16 bit field. This now makes it possible to
172 send list of errors. Updated the protocol specs and the code
173 in core library, client library and server. Protocol TODO #1.
174 Affected files are lib/silccore/silccommand.[ch],
175 lib/silcclient/command_reply.[ch], silcd/command.c,
176 silcd/command_reply.c and silcd/packet_receive.[ch].
178 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
180 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
181 must be handled by the application and should tell the application
182 that an error message was already printed, and it should print the
183 config coords (line, filename, ...). Affected files are
184 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
186 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
187 server config parsing code more readable.
189 Fixed a bug in the fetch_logging() config callback.
191 Affected files is silcd/serverconfig.c.
193 * Drop root privileges when started in foreground. Don't drop them
194 if debugging also. Affected file is silcd/silcd.c.

199 for setting various presence information. Added new modes:
200 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
201 specs and code. Protocol TODO #19. Affected files are
202 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
203 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
205 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
207 * Added STATS command to the protocol after all, to return
208 various statistical information about the network. It can
209 be used by clients to retrieve statistical information, and
210 servers may use it to to fetch cell and network wide
211 statistics from router. Updated the protocol specs and
212 implemented it to the server. Protocol TODO #16.
213 Affected files are lib/silccore/silccommand, silcd/command.[ch],
214 silcd/command_reply.[ch].
216 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
218 * The LIST command reply in client libary now adds new channel
219 entry if the returned channel doesn't exist yet in cache,
220 and returns the channel entry to the application in the
221 command_reply client operation. Affected file is
222 lib/silcclient/command_reply.c.
224 * Changed the channel message payload's MAC generation to
225 include the IV in the MAC as well. This way all relevant
226 parts of the channel message payload are authenticated also
227 with the channel message MAC (and not only by packet MAC).
228 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
229 Affected file is lib/silccore/silcchannel.c.
231 * Fixed the SKE to save the remote version, since the
232 silc_ske_parse_version mistakenly checked wrong version,
233 after it replaced the start payload. Affected files are
234 lib/silcske/silcske.[ch].
236 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
238 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
239 string utility functions. Added there also new functions
240 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
241 Affected files lib/silcutil/silcstrutil.[ch].
243 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
244 files are lib/silcutil/silcstrutil.[ch].
246 * Defined that the security property fields in SKE SHOULD be
247 UTF-8 encoded, defined that version string MUST be US-ASCII
248 encoded, defined that passphrases sent in connection
249 authentication protocol MUST be UTF-8 encoded. Implemented
250 these to the client and server. Defined also that other
251 passphrases sent in the protocol MUST be UTF-8 encoded.
252 Affected files are lib/silcske/silcske.c,
253 lib/silcclient/protocol.c, silcd/protocol.c,
254 silcd/serverconfig.c, and lib/silccore/silcauth.c.
256 * Changed the silc_client_close_connection interface to not
257 need the SilcSocketConnection which should not be visible
258 to application. Affected files are lib/silcclient/client.c
259 and lib/silcclient/silcclient.h.
261 * Rewrote the text for Private Message Key Payload in the
262 protocol specification. Protocol TODO #11.
264 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
266 * Upgraded the protocol version to 1.1, updated protocol specs
269 * Added the nickname as new argument to NICK_CHANGE notify and
270 added it to protocol specs and implemented it to client and
271 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
272 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
273 lib/silcclient/client_notify.c.

276 it to protocol specs and implemented it to client and server.
277 Protocol TODO #13. Affected files are silcd/command.c,
278 silcd/packet_receive.c, packet_send.[ch],
279 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
280 The killer's client entry is now returned to application in
281 the `notify' client operation.
283 * Fixed the Max Argument fields that had too large value set
284 in the protocol specs. Protocol TODO #14.
286 * Added the LEAVE command reply to return the ID of parted
287 channel. Updated protocol specs and implemented it to the
288 client and server. Protocol TODO #15. Affected files are
289 silcd/command.c, lib/silcclient/command_reply.c. The channel
290 entry is now returned to application in the `command_reply'
293 * Rewrote the version SKE version checking in client libary
294 and in server to use the silc_parse_version_string. Affected
295 files are lib/silcclient/protocol.c, silcd/protocol.c.
297 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
298 commands that was missing it, and updated protocol specs and
299 the server implementation. Protocol TODO #10. The affected
300 file is silcd/command.c.
302 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
303 generic reply to a generic request (REQUEST flag), and
304 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
305 way. A draft-riikonen-silc-flags-payloads-00.txt is written
306 to define the payload for DATA flag. Added the flags to
307 the implementation. Protocol TODO #9. Affected file is
308 lib/silccore/silcchannel.h.
310 Changed the client library to return the message length
311 to application as well in the channel_message and private_message
312 client operations. Affected files are
313 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
314 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
315 and lib/silcclient/client_ops_example.c.
317 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
318 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
319 the channel. Updated protocol specs and impelemented this
320 to client and server. Protocol TODO #6. Affected files are
321 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
322 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
324 Added new options m and M to CMODE command in Irssi SILC
325 client to set these modes.
327 * Deprecated all administrative commands from SILC protocol
328 since they are highly implementation specific commands.
329 Updated protocol specs. Moved the old commands in
330 implementations to private range of command types. Affected
331 files are silcd/command.c, lib/silcclient/command.c and
332 lib/silcclient/command_reply.c. Protocol TODO #8.
334 * Fixed a bug in server where sending unknown command crashes
335 the server. Affected file silcd/command.c.
337 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
339 * Added SILC_PROTOCOLVERSION macro to check protocol version
340 of a socket connection. The affected file is
341 lib/silcutil/silcsockconn.h.
343 * Added better error logging in rekey protocol. Affected file
346 * Do not check public key types in SKE during rekey. Affected
347 file lib/silcske/payload.c.
349 * Fixed the rekey protocol with PFS, which was totally broken.
350 Affected file silcd/protocol.c.
352 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
354 * Some client implementations quit network by doing first LEAVE
355 and then immediately SIGNOFF (like Bombyx). We now do check
356 after a short time after LEAVE notify and check whether the
357 client is still valid after LEAVE, and if not we remove it from
358 cache. Affected file is lib/silcclient/client_notify.c.
360 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
362 * Merged version 1.1.4 of zlib. Even if it not currently in use,
363 it's good not to have security holes here.
365 * Fixed a negative refcount situtuation for the config context.
366 Affected file is silcd/serverconfig.c.
368 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
370 * ROBOdoc documented lib/silcutil/silcutil.h.
372 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
374 * Optimized even more the SilcPacketContext structure. Now
375 totally saved 16 bytes of memory per context after optimization.
376 Affected files are lib/silccore/silcpacket.[ch].
378 * Made strict checks for valid SILC IDs. Affected file is
379 lib/silccore/silcid.c.
381 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
383 * Changed the object argument for silc_cipher_register,
384 silc_hash_register, silc_hmac_register and silc_pkcs_register
385 to const. Affected files are lib/silccrypt/silccipher.[ch],
386 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
388 * Changed the silc_get_username and silc_get_real_name to
389 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
391 * Fixed the Irssi SILC Client to use the silc_get_username and
392 silc_get_real_name insted of glib routines since the glib
393 routines only corrupt stack. Fixes the Irssi SILC to work in
394 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
396 * Fixed the Irssi to not use g_get_home_dir since it crashes
397 or returns garbage on cygwin and corrupts stack. Added function
398 get_home_dir to Irssi routines. Affected files are
399 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
401 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
403 * Made some structure optimizations. SFTP memory FS MemFSEntry
404 entry structure. Optimized SilcTask structure. Optimized
405 SilcPacketContext structure.
407 Affected files lib/silcsftp/sftp_fs_memory.c,
408 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
410 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
412 * And yet again reverted back the config thing since Johnny
413 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
416 * Fixed memory leaks from config object. Affected files are
417 silcd/serverconfig.[ch].
419 * Added support for adding new connections to the server in rehash.
420 After rehash they take effect.
422 Added support for changing the maximum allowed connections in
423 rehash. The number can grow but going smaller is not supported.
425 Added function silc_server_num_sockets_by_remote to the
426 silcd/server_util.[ch].
428 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
430 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
432 * Added preliminary checking during config parsing for a valid
433 public/private key and removed further checks in the code.
434 Affected files are silcd/serverconfig.[ch], server.c.
436 * Moved functions silc_server_drop() and silc_server_daemonise()
437 from server.c to silcd.c since they are stricly related to
438 the application activity.
440 * Reverted a small part of the automatic ref/unref since
441 it caused a double unref in some situations. Affected
442 files are silcd/silcd.[ch], server.c, serverconfig.c.
444 * Added some .cvsignore files in the lib directory.
446 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
448 * Fixed silc_net_gethostbyaddr to correctly resolve by
449 address. Affected file lib/silcutil/silcnet.c.
451 * Fixed the notify relaying to client. The HMAC to be used
452 with relayed packets ws wrong and caused decryption failure
453 at the client end. Affected file is silcd/packet_receive.c.
455 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
457 * Created new branch silc_protocol_1_0_branch.
459 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
461 * Changed the silc_server_config_* routines to be SilcServer
462 independent. They are now officially application specific code
463 and not part of generic server implementation. Affected files
464 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
466 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
468 * Added automatic referencing of config context in the
469 silc_server_config_alloc, and automatic unreferencing in the
470 silc_server_config_destroy. Affected files are
471 silcd/serverconfig.[ch], silcd/silcd.c.
473 * Fixed the silc_log_quick handling in the logging routines.
474 It didn't log quickly when it was TRUE. Affected file is
475 lib/silcutil/silclog.c. Also the flush delay was set even
476 if it was 0 in config file. Affected file is
477 silcd/serverconfig.c.
479 * Added support for changing key pair of the server in rehash.
480 Affected file silcd/server.c.
482 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
484 * Fixed the TOPIC_SET notify to not cras. It changed the topic
485 too early, before getting the channel entry. Affected file
486 is silcd/packet_receive.c.
488 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
490 * Added functions silc_server_config_[ref/unref], these are used
491 to prevent that the config object is destroyed.
493 No longer directly affect global variables silc_log_quick and
494 silc_log_delay, they are first cached inside the config object
495 and then applied with silc_server_config_setlogfiles().
497 silc_server_config_set_defaults() is now internal to
498 serverconfig.c, there are no reasons to show this internal stuff
501 Affected files are silcd/serverconfig.[ch].
503 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
504 fprintf's to stderr, since some code may be executed again after
505 the server went into the background. Affected files are
508 * Added rehash support. Added function silc_server_rehash() that
509 will perform all the basic tasks of the rehashing procedure.
511 * Added command line option `-x, --hexdump'. This will enable the
512 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
513 The option `--hexdump' implies `--debug'.
515 * Fixed a bad bug in the logging APIs (silcutil library) where
516 the application would crash after calling silc_log_reset_all().
518 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
520 * Fixed the KICKED notify handling in client library to
521 correctly remove the channel and all entries from the
522 channel when I was kicked. This bug crashed the client.
524 Fixed yet another but in KICKED notify handling to remove
525 the kicked client correctly from the channel.
527 Affected file is lib/silcclient/client_notify.c.
529 * Fixed a minor bug in looking up correct client entry
530 in KICKED notify in server. Affected file is
531 silcd/packet_receive.c.
533 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
534 sources correctly to distribution. Fixes --with-gmp option.
536 * Removed the manual rehashing from ID Cache, and changed it
537 to use the SILC Hash Table's auto rehash feature. Affected
538 file is lib/silccore/silcidcache.c.
540 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
542 * Fixed a bug in the silc_client_nickname_format function that
543 handles the multiple same nickname formatting. Two clients
544 with same nickname caused problems after the first one left
545 and rejoined. It didn't format the nickname correctly.
546 Affected file is lib/silcclient/idlist.c.
548 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
550 * Don't change the topic if olod topic is same as new one.
551 Affected file is silcd/packet_receive.c.
553 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
555 * Added cross-reference support to the SILC Documentation
556 generator. All types across all HTML files are now cross-
557 referenced. Affected files util/robodoc/generator.c and
558 scripts/silcdoc/silcdoc.
560 * Added file lib/silcutil/silctypes.h to include all the
561 arithmetic type definitions and some macros. Removed
562 includes/bitmove.h and moved macros to silctypes.h.
564 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
566 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
568 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
570 * Added `type' argument to silc_id_payload_parse_id function which
571 now returns the type of the ID to the sent pointer. Affected
572 file is lib/silccore/silcid.[ch].
574 * Added check for CMODE_CHANGE notify type that mode change is
575 allowed by the sender. Affected file silcd/packet_receive.c.
577 * Added check for CUMODE_CHANGE notify type that mode change is
578 allowed by the sender. Affected file silcd/packet_receive.c.
579 Added the ID type as CUMODE_CHANGE notify type as argument
580 to the `notify' client operation. Affected files are
581 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
583 * Added function silc_client_add_server to the client library.
584 Added support for resolving also channel and server info when
585 received unknown entity in notify packet. Affected files are
586 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
588 * Added function silc_command_get_status to return the command
589 status from the command reply's argument payload. Affected files
590 are lib/silccore/silccommand.[ch].
592 * Added check for KICKED notify type that the kicking is
593 allowed by the client. Affected file silcd/packet_receive.c.
595 * Created function silc_get_input which can be used to get input
596 (echo on or off) from user on command line. Affected files are
597 lib/silcutil/silcutil.[ch].
599 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
601 * Optimized silc_server_packet_relay_to_channel function.
602 Added new function silc_channel_message_payload_encrypt which
603 can be called directly if channel message payload needs to
604 be encrypted and is already encoded (no need to call _encode
605 function). Packet relaying is now done by router without any
606 extra memory allocations. Affected files are
607 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
610 * Fixed the INVITE notify handling. It took wrong arguments
611 as invite list and invite delete. Affected file is
612 silcd/packet_receive.c.
614 * Added check for TOPIC_SET notify type that the topic change is
615 allowed by the client. Affected file silcd/packet_receive.c.
617 * Added check for INVITE notify type that inviting is allowed by
618 the client. Affected file silcd/packet_receive.c.
620 * Changed the silc_server_client_on_channel to return the
621 SilcChannelClientEntry as well. Moved the function
622 silc_server_check_cmode_rights to server_util.[ch].
623 Affected files are silcd/server_util.[ch], silcd/command.c.
625 * Added function silc_server_check_umode_rights to check whether
626 changing client's user mode is allowed. Added check for
627 UMODE_CHANGE notify type that the umode change is allowed
628 by the client. Affected files are silcd/server_util.[ch],
629 silcd/packet_receive.c and silcd/command.c.
631 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
633 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
634 ID length. It ignored that ID can be IPv6 based as well.
635 Affected file lib/silccore/silcpacket.h.
637 * Fixed the silc_id_id2str and silc_id_str2id to take the
638 IPv6 address offset's into consideration. Affecte file is
639 lib/silccore/silcid.c.
641 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
643 * Fixed the internal Unix scheduler functions to check for
644 NULL context they may receive. The affected file is
645 lib/silcutil/unix/silcunixschedule.c.
647 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
649 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
650 can specify different directory with --home command line
651 parameter. Affected files irssi/src/silc/core/client_ops.c,
654 * SILC-specific commands aren't now executed if the active server
655 isn't of SILC-type, so there won't be problems with having
656 IRC and SILC protocol support in same client. Affected files
657 irssi/src/silc/core/silc-channels.c, silc-servers.c,
660 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
662 * Improved the signal support in SILC Schedule. Added new
663 function silc_schedule_signal_call which is used by application
664 to mark a signal to be called. It is now safe to perform
665 any kind of tasks in signal callbacks since it is guaranteed
666 that the application specified signal callback is called
667 after the signal is over. Affected files are
668 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
670 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
672 * Added `name' field to SilcChannelPrivateKey to represent
673 application given name for the key. Moved also the context from
674 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
675 Added the `name' argument also to the function
676 silc_client_add_channel_private_key.
678 Added function silc_client_current_channel_private_key to set the
679 current channel private key in use.
681 Added "change" command to KEY command which can be used to change
682 the current channel private key. Bound the command also to
685 Also affected files lib/silcclient/client_channel.c,
686 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
688 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
690 * Added silc_rng_get_byte_fast function in to the
691 lib/silccrypt/silcrng.[ch].
693 * Changed the interface of silc_packet_assemble and the
694 silc_packet_send_prepare. If silc_packet_assmble is now
695 called the application does not call silc_packet_send_prepare
696 because the library will call it automatically. These
697 interfaces now also return a reference to the outgoing buffer
698 which includes the assembled packet, which the application can
699 use to encrypt the packet.
701 Affected files are lib/silccore/silcpacket.[ch],
702 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
703 silcd/packet_send.c, server_backup.c and packet_receive.c.
705 * Fixed a packet sending bug on very high load, where outgoing
706 packet queue wasn't handled correctly and packets got corrupted.
707 Affected files are lib/silcutil/*/silc*sockconn.c,
708 lib/silcclient/client.c and silcd/server.c.
710 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
712 * Added macro SILC_PACKET_DATALEN which can be used during
713 packet assembling to check whether the data to be added to
714 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
715 len is truncated until it fits it.
717 Added checks for maximum length of channel message payload and
718 private message payload also.
720 Added checks for maximum packet length in server and in
723 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
724 lib/silcclient/client.c, lib/silccore/silcchannel.c and
725 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
726 lib/silcclient/client_prvmsg.c.
728 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
730 * Added silc_server_packet_queue_purge call to the
731 silc_server_disconnect_remote to assure that all data in the
732 queue before disconnecting is sent to the network. Affected
735 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
737 * Added the deleting of server's own ID cache entry to the
738 silc_server_free function. Free also everything else that
739 has been allocated in silc_server_init. The affected file
742 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
744 * Added functions silc_parse_version_string, silc_version_to_num,
745 and silc_ske_parse_version to parse SILC protocol style version
746 strings. Affected files lib/silcutil/silcutil.[ch] and
747 lib/silcske/silcske.[ch].
749 * Added new configuration params: version_protocol, version_software
750 and version_software_vendor to specify what version the remote
751 host must at least be to be able to connect to server. The vendor
752 string can be regex matched too. Added new function
753 silc_server_connection_allowed to check maximum number of allowed
754 connections, and allowed versions for incoming connections.
755 Affected files are silcd/server.c, server_util.[ch] and
758 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
760 * Added preliminary support for signals in scheduler. The
761 signals we care about are now blocked always when the scheduler
762 is locked. This way we can synchronise the use of signal with
763 scheduler. It is guaranteed that when signal occurs the scheduler
764 is not locked, and thus new tasks can be safely added to the
767 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
768 to silc_schedule_internal_init and silc_schedule_internal_uninit.
769 Added new platform specific routines
770 silc_schedule_internal_signals_[un]block and
771 silc_schedule_internal_signal_[un]register.
773 Added new functions to SILC Schedule API:
774 silc_schedule_signal_[un]register. Each signal that application
775 is going to use should be registered to the scheduler.
777 Affected files are lib/silcutil/silcschedule.[ch],
778 lib/silcutil/*/silc*schedule.c.
780 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
782 * Check for unauthenticated client and server in the
783 silc_server_new_client and silc_server_new_server functions.
784 Affected file silcd/packet_receive.c.
786 * Added function silc_string_is_ascii to check whether given
787 string is 7-bit ASCII string. Affected files are
788 lib/silcutil/silcutil.[ch].
790 * Added function silc_id_is_valid_server_id into the
791 silcd/serverid.c and added checking for valid Server ID's in
792 silc_server_new_server. The Server ID must always be based
793 on the server's public IP address.
795 * Added logging of DISCONNECT packet message in the server.
796 Affected file silcd/server.c.
798 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
800 * Changed all library interfaces that use Global RNG to also
801 accept SilcRng as argument. Affected files are
802 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
803 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
804 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
805 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
808 * Added function silc_pkcs_generate_key to the
809 lib/silccrypt/silcpkcs.[ch] for applications so that they
810 don't need to do pkcs->pkcs->init calls anymore.
812 * Remove SilcSocketConnection from the SFTP API since it really
813 wasn't needed there. The application has the information
814 saved in its contexts anyway and the SFTP layer doesn't need
815 know about it. Affected files lib/silcsft/silcsftp.h and
816 lib/silcsftp/sftp_[server/client].c.
818 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
819 The SilcSimContext is not SilcSim.
821 * Fixed possible buffer overflows in silc_id_render in the
822 lib/silcutil/silcutil.c.
824 * On EPOC the global crypto module lists are not used at all
825 in the crypto library. Added support for using the constant
826 algorithm list on EPOC. Affected files are
827 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
830 * Fixed the handling of third parameter of KICKED notify, since
831 it was mistakenly updated to SILC Protocol 1.0 even though it
832 is to be included in 1.1. Since it is not in 1.0 it is not
833 mandatory, and this fix now handles it only if it is provided,
834 and it is not error if it is not provided. Affected file
835 lib/silcclient/client_notify.c.
837 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
839 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
840 client. Affected file irssi/src/silc/core/client_ops.c.
842 * Merged with Irssi 0.8.4 from irssi.org CVS.
844 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
846 * Check for valid socket connection in client entries before
847 sending any messages. Fixes a crash, but doesn't fix some
848 other underlaying bug that is lurking there. Affected
849 file silcd/packet_send.c.
851 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
853 * $usermode, $cumode and $cumode_space expandos shouldn't do
854 anything with non-SILC server records. Affected file
855 irssi/src/silc/core/silc-expandos.c
857 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
859 * Fixed the silc_net_check_[host/local]_by_sock to support
860 IPv6 bound sockets as well. Now they can return IPv6 addresses
861 as well. Affected file lib/silcutil/silcnet.c.
863 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
864 Affected lib/silcutil/unix/silcunixnet.c.
866 * Fixed ID rendering (at least on some platforms, not NetBSD)
867 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
869 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
871 * Added silc_hash_public_key and silc_hash_public_key_compare
872 functions to be used with SilcHashTable. They can be used to
873 hash public keys and compare public keys in hash table. Affected
874 file lib/silcutil/silcutil.[ch].
876 * Added support for specifying multiple public keys for Client
877 connection section in server configuration file. This makes it
878 possible to accept multiple public keys from same host, or to
879 make a section that accepts any incoming host, and have the
880 accepted public keys listed in the section.
882 Added functions silc_sever_[find/get]_public_key, added the
883 support for this actually to all connection sections but only
884 the Client section is currently allowed to specify multiple
887 Affected files are silcd/server.c, server_internal.h,
888 command.c, protocol.c, server_util.[ch], packet_receive.c.
890 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
892 * Merged Irssi 0.8.2 from irssi.org CVS.
894 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
896 * If silc_debug is TRUE, also output standard logging messages
897 to stderr with the debug output.
899 Made silc_log_reset_all() flushing all channels before returning.
900 Also fixed some documentation typos.
902 Affected files are lib/silcutil/silclog.[ch].
904 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
906 * Fixed the server to check correctly the amount of connections
907 from single host, by checking also the type of the connection.
908 Fixed also the comparison of number of connections and number
909 of allowed connections. Affected files are silcd/server.c,
912 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
914 * Fixed the USERS command reply to save the user's mode on the
915 channel as well. Fixed JOIN command reply to check whether a
916 client is on channel already and not join it twice. Affected
917 file lib/silcclient/command_reply.c.
919 * Added new file silc-expandos.c into irssi/silc/core/ to return
920 various stuff for various signal for the statusbar etc. updating.
921 Now Irssi SILC client prints channel user modes etc. on the
924 * The user mode (like server/router operator changes) is now shown
925 on the Irssi SILC client's statusbar. The affected files are
926 irssi/src/silc/core/client_ops.c, silc-expandos.c.
928 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
930 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
931 to SILC_SCHEDULE_[UN]LOCK macros.
933 * Added more error printing to logs in server code. Affected
934 files silcd/server.c and silcd/protocol.c.
936 * Fixed -S option parsing in Irssi SILC Client. Affected file
937 irssi/src/silc/core/silc-core.c.
939 * Added silc_buffer_alloc_size function. Affected file is
940 lib/silcutil/silcbuffer.h.
942 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
944 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
945 constants. Affected files in
946 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
949 * Changed the internal SFTP Memory FS table to const. Affected
950 file lib/silcsftp/sftp_fs_memory.c.
952 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
954 * Fixed the buffer formatting and unformatting routines to
955 check the size of 64 bits types with sizeof(). Affected
956 file is lib/silcutil/silcbuffmt.c.
958 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
960 * Removed 0.6.x backwards support.
962 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
964 * Changed all integer type names:
965 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
966 to avoid collisions with other libraries using same type names
969 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
971 * Added `prefer_ipv6' argument to the functions
972 silc_net_gethostbyname[_async]. If it is TRUE it will return
973 IPv6 address over IPv4. If FALSE IPv4 address is returned
974 even if IPv6 address was found. Affected files
975 lib/silcutil/silcnet.[ch].
977 * Added support silc_net_create_connection[_async] to fallback
978 to IPv4 address if IPv6 address could not be used (like if
979 it doesn't work on a specific system). Affected file in
980 lib/silcutil/unix/silcunixnet.c.
982 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
984 * Added silc_schedule_reinit function to do the enlarging
985 of the max tasks handling capabilities of the scheduler.
986 Affected files lib/silcutil/silcschedule.[ch].
988 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
990 * Added automatic extern "C" { ... } for C++ compilers so the
991 application does not need to define them. Affected file
992 includes/silcincludes.h.
994 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
995 old name went against naming convention. Applications now
996 include "silcclient.h" instead of "clientlibincludes.h".
997 Removed includes/clientlibincludes.h, it is redundant now.
999 * Renamed includes/version.h to silcversion.h.
1001 * Added really preliminary support for OS/2 into the util
1002 library. Only thread & mutex API is implemented, others
1003 are still to be implemented. Created the lib/silcutil/os2/
1004 directory. Created also file includes/silcos2.h.
1006 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1008 * Added preliminary BeOS support into the util library.
1009 Created lib/silcutil/beos/, and implemented all the needed
1010 functions to support SILC on BeOS. Created also file
1011 includes/silcbeos.h.
1013 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1015 * Added proper initializations to silc's irssi code, so it's
1016 now possible to load it as module. Affected files
1017 irssi/src/silc/core/silc-core.c,
1018 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1020 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1022 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1025 * Fixed the silcdoc document generator to correct generate
1026 docs from all kinds of filenames. Affected files are
1027 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1029 * ROBOdoc documented lib/silcutil/silcmemory.h.
1030 Added also new function silc_memdup.
1032 * Removed lib/silcutil/silcbufutil.h and moved those routines
1033 to the lib/silcutil/silcbuffer.h.
1035 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1037 * Added `user_count' to the SilcChannelEntry which now tells the
1038 number of users on the channel. The user count is now saved
1039 in normal server of global channels as well. Affected files
1040 silcd/server.c, idlist.h, packet_receive.c and command.c.
1042 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1043 include file utility functions.
1045 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1046 instead of calling directly OS routines.
1048 * Fixed NICK change printing in Irssi SILC Client. Fixed
1049 KICKED notify printing in Irssi SILC Client. Affected file
1050 irssi/src/silc/core/client_ops.c.

1059 the SKE interface a bit.
1061 * Fixed padding problem in PKCS#1. The padding was not actually
1062 random since the random number generator was used incorrectly.
1063 This security bug affects only when encrypting with PKCS#1, and
1064 it is not currently used at all in SILC. SILC only use signing
1065 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1122 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1124 * Fixed command line parameter handling. All SILC initialization
1125 is now done in silc_core_init() which also fixes autoconnecting
1128 Affected files irssi/src/silc/core/silc-core.c,
1129 irssi/src/fe-text/silc.c.
1131 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1133 * Added new configuration options and blocks:
1134 keepalive_secs, reconnect_count, reconnect_interval,
1135 reconnect_interval_max, reconnect_keep_trying and
1136 require_reverser_lookup. Added ConnectionParam block, and
1137 implemented the connection parameters when connecting as
1138 initiator and when accepting connections as responder.

1150 the connection configuration object from the SilcServerConnection
1151 object instead of finding it during the connecting phase.
1152 Added the configuration object to SilcServerConnection struct.
1153 Affected files silcd/server_internal.h, server.c.
1155 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1157 * Add the client on channel after it was resolved at the
1158 channel message receiving, and it was not already on the
1159 channel. Affected file lib/silcclient/client_channel.c.
1161 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1177 authentication to be set at the same time.
1179 Added `prefer_passphrase_auth' setting in config file which
1180 can be used to set to prefer passwd auth if both passwd and
1181 public key is set. If not set, public key is preferred.
1182 This has effect only when being initiator (responder will try
1185 Added support for authentication with passphrase and public key
1186 at the same time. The passphrase is tried first always since
1187 it is faster to check.
1189 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1191 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1193 * Merged the new SILC Config library, with the server parsing

1237 * Fixed the file transfer's key agreement payload to include
1238 zero port also if the hostname is NULL because it could not
1241 Call file transfer monitor callback now also if error occurs
1242 during key agreement protocol.
1244 Changed the silc_client_file_send interface to return the
1245 SilcClientFileError instead of session id. The session ID
1246 is returned into pointer provided as argument.
1248 Check that the file exists locally before sending the
1249 file transfer request at all.
1251 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1253 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1254 error than can occur while key agreement protocol. Affected
1255 file lib/silcclient/silcapi.h.

1263 file lib/silcutil/silclog.c.
1265 * Fixed the channel message payload decryption in the function
1266 silc_channel_message_payload_decrypt to not modify the original
1267 buffer before it is verified that the message decrypted
1268 correctly. Otherwise, next time it is called with correct
1269 channel key it won't encrypt since the payload is corrupted.
1270 Affected file lib/silccore/silcchannel.c.
1272 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1284 * Fixed a bug in hash table internal routine for traversing
1285 the table with foreach callback. The current entry may
1286 become invalid in the callback but it was referenced after
1287 the callback returned.
1289 Do not allow auto rehashing of hash table during the
1290 silc_hash_table_foreach operation, for same reasons as it is
1291 not allowed for SilcHashTableList. Affected files are
1292 lib/silcutil/silchashtable.[ch].
1294 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1300 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1302 * Fixed private message handling. It used some old code that
1303 caused the client to crash. Affecte file is
1304 lib/silcclient/client_prvmsg.c.
1306 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1308 * Added function silc_client_add_channel,
1309 silc_client_replace_channel_id, and removed functions
1310 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1311 from client library.
1313 * Added cross reference of the joined channels to the
1314 SilcClientEntry, and changed the SilcChannelEntry's
1315 users list to SilcHashTable. The affected files are
1316 lib/silcclient/idlist.[ch].
1318 * Fixed a bug in hash table tarversing. While the hash table
1319 is traversed with SilcHashTableList the table must not be
1320 rehashed. It is now guaranteed that auto rehashable tables
1321 are not rehashed while tarversing the list. Also defined that
1322 silc_hash_table_rehash must not be called while tarversing
1323 the table. Added function silc_hash_table_list_reset that must
1324 be called after the tarversing is over. The affected files are
1325 lib/silcutil/silchashtable.[ch].
1327 * Changed all hash table traversing to call the new
1328 silc_hash_table_list_reset in server and in client library.
1330 * Added function silc_client_on_channel to return the
1331 SilcChannelUser entry if the specified client entry is joined
1332 on the specified channel. This is exported to application as
1333 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1335 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1337 * Fixed founder regaining problem with JOIN command on normal
1338 server. The notify for mode change must be sent always and
1339 not only if !cmd->pending. Affected file silcd/command.c.
1341 * Fixed the WHOWAS command's reply sending to support the
1342 lists correctly. Affected file silcd/command.c.
1344 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1346 * When sending JOIN command to router for processing the
1347 sender's old command identifier was not saved back to the
1348 sender's command context, fixed now. The affected file is
1351 * Create the key in JOIN command of the router did not return
1352 the channel key, added check for this. Affected file is
1355 * Fixed a channel ID update bug in JOIN command reply. Do
1356 not directly upgrade the ID but call the function
1357 silc_idlist_replace_channel_id if the ID was changed.
1358 Affected file silcd/command_reply.c.
1360 * Fixed memory leaks from command calling if it would fail.
1361 Affected file silcd/command.c.

1373 * Removed TRQ from lib/trq, not needed anymore.
1375 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1376 with server connections. Later this will be configurable
1377 in config file after new config file is done. Affected file
1380 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1382 * Fixed a crash in server related to channel announcements.
1383 Affected file silcd/server.c.
1385 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1387 * Fixed memory leaks in silc_server_create_new_channel*
1388 functions. Affected file silcd/server.c.
1390 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1391 which ID was changed. This way the router will send the
1392 user list for the channel again, and server won't be in
1393 desync in some rare circumstances. Affected file is
1394 silcd/packet_receive.c.
1396 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1411 file for application programmers to quickly start using
1412 the SilcClientOperation functions in their application.
1413 Updated the lib/silcclient/README as well to tell about this
1414 nice file made available.
1416 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1418 * Call silc_server_remove_from_channels when removing client
1419 entry when NO_SUCH_CLIENT_ID was received. Affected file

1424 * Added server & router operator statistics updating. Affected
1425 file silcd/packet_receive.c and silcd/command.c.
1427 * Fixed the SERVER_SIGNOFF notify handling on normal server
1428 not to save the history information for clients. Same was
1429 fixed earlier in remove_clients_by_server function, but not
1430 here. Affected file silcd/packet_receive.c.
1432 * Raised the default connection-retry count from 4 to 7 in
1433 server. Affected file silcd/server.h.
1435 * Cancel any possible reconnect timeouts when we start the
1436 key exchange. Affected file silcd/server.c.
1438 * Do not reconnect on connection failure when SCONNECT was
1439 given. Affected files silcd/server.[ch].
1441 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1443 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1445 * Fixed the NICK command to always give the unformatted
1446 nickname to the one giving the NICK command. If unformatted
1447 nickname is cached already it will be formatted and the
1448 local entry will always get the unformatted nickname.
1449 Affected file lib/silcclient/idlist.c.
1451 * Fixed some double frees from client library commands.
1452 Affected file is lib/silcclient/command.c.
1454 * Fixed CUMODE command in server to assure that no one can
1455 change founder's mode than the founder itself, there was a
1456 little bug. Affected file silcd/command.c.
1458 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1460 * Removed the SilcClientCommandDestructor from the client
1461 libary, it is not needed anymore. Affected files are
1462 lib/silcclient/silcapi.h, command[_reply].[ch],
1463 client_notify, idlist.c.
1465 * Fixed GETKEY command to first resolve client, and then
1466 resolve the server only if the client was not found, instead
1467 of resolving both at the same time. Affected file is
1468 lib/silcclient/command.c.
1470 * Added silc_client_start_key_exchange_cb and lookup the
1471 remote hostname and IP address before starting the key
1472 exchange with server. The affected file is
1473 lib/silcclient/client.c.
1475 * The server's public key is now saved using the IP address
1476 of the server and not the servername for the filename.
1477 The hostname public key filename is checked as an fall back
1478 method if the IP address based filename is not found.
1480 Fixed the GETKEY command to save the fetched server key
1481 in correct filename.
1483 Print the remote server's hostname now when new key is
1484 received during connection process. Affected file is
1485 irssi/src/silc/core/client_ops.c.
1487 * Return always our own public key to the client if it asks
1488 for it with GETKEY command. Affected file silcd/command.c.
1490 * Removed the use_auto_addr variable from default config
1491 file since it was in wrong section. Affected file is
1494 * Fixed TOPIC_CHANGE notification to not route it when it
1495 was sent using silc_server_send_notify_to_channel function.
1496 Affected file silcd/command.c.
1498 * Fixed silc_server_send_notify_kicked to send the kicker's
1499 Client ID also, it was missing. Affected files are
1500 silcd/command.c, silcd/packet_send.[ch].
1502 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1504 * Do not save client history information in SERVER_SIGNOFF.
1505 Fixes the bug in normal server that it does not detect
1506 the client becoming valid after the server becomes back
1507 online. Affected file silcd/server_util.c.
1509 * Added `sock_error' field into the SilcSocketConnection
1510 context. When error occurs during socket operation (read
1511 or write) the error is saved. Added also new function
1512 silc_socket_get_error to return human readable socket error
1513 message. Affected files are lib/silcutil/silcsockconn.[ch],
1514 lib/silcutil/unix/silcunixsockconn.c, and
1515 lib/silcutil/win32/silcwin32sockconn.c.
1517 * The server now prints the socket error message in the
1518 signoff for client. Affected file silcd/server.c.
1520 * Fixed the `created' channel information sending from router
1521 to server in JOIN command. Checks now whether the channel
1522 really was created or not and set it according that.
1524 Fixed the JOIN command to use the client entry's current
1525 ID during the joining procedure instead of the one it sent
1526 in the command (it is checked though), since it can change
1527 between the packet processing and command processing, and
1528 would just case unnecessary pain in the client end. Affected
1529 file silcd/command.c.
1531 * Fixed a channel key payload sending to use correct channel
1532 ID when the server was forced to change the channel's ID by
1533 router. Router sent the key payload with the old Channel ID.
1534 Affected file silcd/packet_receive.c.
1536 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1538 * Call silc_server_save_channel_key only if the key payload
1539 was provided in the JOIN command's command reply. Affected
1540 file silcd/command_reply.c.
1542 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1544 * Fixed silc_mp_sizeinbase to return the value correctly with
1545 MPI. Affected file lib/silcmath/mp_mpi.c.
1547 * Fixed the stop_server signal to correctly stop the scheduler
1548 and gracefully stop the server when SIGTERM or SIGINT signals
1549 are received. Affected file silcd/silcd.c.
1551 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1553 * Simple handling of TERM and HUP signals. Also added some log
1554 flushing call around. Affected file is
1557 * Fixed small bugs in silclog.c. Now buffering output will take
1558 effect after 10 seconds since startup: This will ensure that
1559 no important startup messages are lost. Also output redirection
1560 will preserve original format ([Date] [Type] message).
1561 Affected file is lib/silcutil/silclog.c.
1563 * Added two options to the config file, in the logging section:
1564 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1565 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1567 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1569 * Do not print the warning about log files not being initialized
1570 more than once to avoid excess logging. Affected file is
1571 lib/silcutil/silclog.c.
1573 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1574 the SIM copying in make install in Makefile.am.pre.
1576 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1578 * Rewritten silclog APIs. Globally interesting changes follows:
1579 silc_log_set_files() changed to silc_log_set_file().
1580 silc_log_set_callbacks() changed to silc_log_set_callback().
1581 ROBOdoc documented silclog header file.
1582 SilcLogCb now returns bool to wether inihibit the default
1583 handler or not (to keep the old behaviour return always TRUE).
1584 The new APIs should also fix the problem of the
1585 silcd_error.log file that was written in the current directory.
1588 Log files streams will remain opened after silc_log_set_file()
1589 call, means less CPU usage notably on high traffic servers.
1590 File streams are now full buffered, and flushed to the disk
1591 every 5 minutes, lesses HD activity and CPU usage.
1592 Messages can be redirected, allowing admins to configure
1593 one single logfile for all server messages.
1594 the silc_log_quick global variable to activate fast-logging.
1595 Affected files lib/silcutil/silclog.[ch]
1597 * Changed some code to conform new silclog APIs. Affected
1598 files are doc/example_silcd.conf.in, silcd/server.c
1599 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1602 * Fixed a memory leak that could occur in some situations.
1603 Affected file silcd/serverconfig.c.
1605 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1607 * Added the silc_client_del_client to remove the client from
1608 all channels as well. Affected file lib/silcclient/idlist.c.
1610 * Fixed the client library to correctly remove the client
1611 from all channels when the client entry is being destroyed.
1612 Affected file lib/silcclient/client_notify.c, command.c.
1614 * Added auto-nicking support to the client library. If the
1615 applicatio now sets client->nickname it will be sent to the
1616 server after connecting by the library. This way for example
1617 SILCNICK (or IRCNICK) environment variables will have effect
1618 and always change the nickname automatically to whatever
1619 it is wanted. Affected file lib/silcclient/client.[ch].
1621 * Renamed silc_server_command_bad_chars to the
1622 silc_server_name_bad_chars and moved it to the
1623 silcd/server_util.[ch]. Added also new function
1624 silc_server_name_modify_bad to return nickname that
1625 includes bad characters as new nickname without those
1626 bad characters. This check and modify is now used in
1627 silc_server_new_client when the username is initially set
1628 as nickname, so it must be checked to be valid nickname.
1629 Affected file silcd/packet_receive.c.
1631 * The nickname length is now taken from the packet for real
1632 and not trusted to strlen() since it clearly can return
1633 wrong length for nickname including bad characters. This
1634 also applies to channel names. Affected file silcd/command.c.
1636 * Removed the lib/silcsilm/modules directory. Modules are now
1637 compiled into the lib/silcsim. Fixed the copying of the
1638 modules to follow symbolic links in Makefile.am.pre.
1640 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1642 * Fixed silc_string_regexify list creation. Fixes bugs with
1643 BAN and INVITE commands in server. The affected file is
1644 lib/silcutil/unix/silcunixutil.c.
1646 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1648 * Removed the command destructor entirely from the server's
1649 command and command reply routines. It is not needed, and
1650 its usage was buggy and caused crashes. Affected files are
1651 silcd/command[_reply].[ch].
1653 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1655 * Cancel protocol and NULL sock->protocol if timeout
1656 occurred during protocol. Affected file silcd/server.c.
1658 * Cancel protocol timeouts always before calling the final
1659 callback, to assure that after final callback is called
1660 no other state will be called for the protocol anymore.
1661 Affected file silcd/protocol.c.
1663 * Print error log if incoming connection configuration could
1664 not be found. Affected file silcd/server.c.
1666 * Fixed JOIN command to correctly save the founder mode
1667 to the client on normal SILC server, when the channel
1668 was created by the router. Affected file silcd/command.c.
1670 * Fixed LIST command (hopefully) to send correct reply
1671 packets. Affected file silcd/command.c.
1673 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * The silc_packet_receive_process now returns FALSE if the
1676 read data was invalid packet, and TRUE if it was ok.
1678 The server now checks that if unauthenticated connection
1679 sends data and its processing fails the server will close
1680 the connection since it could be a malicious flooder.
1682 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1684 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1686 * Make sure the warning about error opening a log file is
1687 printed only once and not everytime it fails (produces
1688 too much useless log). Affected file lib/silcutil/silclog.c.
1690 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1692 * Made the silc_server_daemonise() function more readable.
1693 Affected file silcd/server.c.
1695 * Pid file is now optional, the user may comment it out from
1696 the config file. Removed define SILC_SERVER_PID_FILE, we
1697 don't need a default any longer. Affected file
1698 configure.in.pre, lib/Makefile.am.pre.
1700 * Make some use of the pid file. The server now dies at startup
1701 if it detects a valid pid file on his path. The server would
1702 die anyway in this circumstance, because of the bind() failure.
1703 Affected file silcd/silcd.c.
1705 * No longer compiling lib/dotconf.
1707 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1709 * Fixed JOIN command parsing not to crash. Affected file
1710 lib/silcclient/command.c.
1712 * Fied the NICK_CHANGE notify to add the new client entry
1713 even it is resolved. This removes an <[unknown]> nick
1714 thingy bug in the client. Affected file is
1715 lib/silcclient/client_notify.c.
1717 * Do not try to allocate 0 bytes (efence does not like it)
1718 in lib/silccore/silccomand.c when encoding payload.
1720 * Do not take IRCNICK as nickname in Irssi SILC client since
1721 it is not possible to set nickname before hand connecting
1722 the server (TODO has an entry about adding auto-nicking
1725 * Changed the silc_server_command_pending to check whether
1726 there already exists an pending entry with the specified
1727 command, command identifier and pending callback. This is
1728 to fix IDENTIFY and WHOIS related crashes that may register
1729 multiple pending commands with same identifier. Affected
1730 file silcd/command.c.
1732 * Fixed the server to reconnect to the router even if it
1733 was already reconnecting and EOF was received. This to
1734 fix a possibility that the server wouldn't ever try to
1735 auto-reconnect to the router. Affected file silcd/server.c.
1737 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * Fixed the server's password authentication to use the
1740 length of the locally saved password, and not the one
1741 sent in the packet. Affected file silcd/protocol.c.
1743 * Fixed same password authentication problem in the
1744 Authentication Payload handling routines in
1745 lib/silccore/silcauth.c.
1747 * Yet another password authentication problem fixed with
1748 channel password handling in silcd/command.c.
1750 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1752 * If first character of string in silc_parse_userfqdn is '@'
1753 then do not parse it. Affected file is
1754 lib/silcutil/silcutil.c.
1756 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1758 * Fixed minor bug in IDENTIFY command reply sending, which
1759 caused various weird problems during JOIN when it was
1760 resolving names for users. Affected file silcd/command.c.
1762 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1764 * Fixed the IDENTIFY command reply sending to chech better valid
1765 clients. It was possible to send incomplete list of replies.
1766 Affected file silcd/command.c.
1768 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1770 * Added silc_client_command[s]_[un]register functions now to
1771 dynamically register the commands in client library. Removed
1772 the static table of commands. This allows the client library
1773 to call commands without causing the application to know about
1774 what commands library has called.
1776 Removed the INFO command reply kludge to detect when the command
1777 was called by library. Now library use its own command reply
1778 function for INFO command.
1780 Added function silc_client_command_call to call a command.
1781 Application can use it to call command, not access the structure
1784 Now all commands that are sent by the client library (not
1785 explicitly sent by application) use own command reply functions.
1787 Affected files around lib/silcclient/ and in
1788 irssi/src/silc/core/.
1790 * Fixed the WHOIS command reply sending to chech better valid
1791 clients. It was possible to send incomplete list of replies.
1793 Fixed the WHOIS and IDENTIFY to send the request to router
1794 if normal server did not do it and did not find any results.
1796 Affected file silcd/command.c.
1798 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1800 * Moved the internal data from SilcClient context into its
1801 own file, not accesible to application. Affected files
1802 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1803 and other files in client library.
1805 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1807 * Added doc/examples installation target in Makefile.am.pre.
1810 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1812 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1813 commands the found client entry will be removed from the
1814 cache, after notifying application about the error. Affected
1815 file lib/silcclient/command_reply.c.
1817 * Changed the /MSG to check for exact nickname user gave, and
1818 not let `nick' match `nick@host' if it is only one found. Now,
1819 user must type the exact nickname (like nick@host2) even if
1820 there are no more than one same nicks found. This is to avoid
1821 a possibility of sending nickname to wrong nickname since
1822 `nick' could match `nick@host'. Affected file is
1823 irssi/src/core/silc-servers.c.
1825 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1827 * Do not print "you are now server operator" or similar when
1828 giving /away command. Affected files are
1829 irssi/src/silc/core/client_ops.c, silc-servers.h.
1831 * Made the silc_server_command_pending_error_check to send
1832 the same command reply payload it received back to the
1833 original sender of the command. This way all arguments
1834 that was received by the server will be received by the
1835 client too. Affected file silcd/command.c.
1837 * Added the silc_idcache_add to return the created cache entry
1838 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1840 * Add global clients to expire if they are not on any channel.
1841 This is because normal server will never know if they signoff
1842 if they are not on any channel. The cache expiry will take
1843 case of these entries. This is done by normal servers only.
1844 The affected files are silcd/command_reply.c,
1845 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1847 * If server receives invalid ID notification for WHOIS or
1848 IDENTIFY and the ID exists in the lists, it is removed.
1849 Affected file silcd/command_reply.c.
1851 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1852 in client then client entry that it matches is searched and
1853 the nickname is printed on the screen for user. Affected
1854 file irssi/src/silc/core/client_ops.c.
1856 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * Use cache entry expire time in the LIST command reply to
1859 purge old entries from the cache after the LIST command
1860 reply has been received. This way we don't have non-existent
1861 entries in the cache for too long. Affected file is
1862 silcd/command_reply.c.
1864 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1866 * If we are normal server, and we've not resolved client info
1867 in WHOIS or IDENTIFY from router, and it is global client,
1868 we'll check whether it is on some channel. If it is not
1869 then we cannot be sure about its validity and will resolve it
1870 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1871 file silcd/command.c.
1873 * Search channel by name (if possible) rather than by ID
1874 in IDENTIFY command's command reply. Affected file is
1875 silcd/command_reply.c.
1877 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1879 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1880 Updated specs and implemented it. Affected file silcd/command.c,
1881 silcd/packet_send.c and silcd/packet_receive.c.
1883 * Implemented the <founder auth> payload handling in the JOIN
1884 command. If provided all conditions for channel joining
1885 except requirement to provide correct passphrase can be
1886 overrided by the channel founder. Updated the protocol specs.
1887 Affected file silcd/command.c.
1889 Added support for founder auth in JOIN command in client
1890 library. Fixed the parsing of the JOIN command now to support
1891 all options as they should be. The affected file is
1892 lib/silcclient/command.c.
1894 * Optimized the WHOIS and IDENTIFY commands to send the request
1895 to router only if it includes nicknames or other names. If
1896 they include only IDs then check the local cache first before
1897 routing. Affected file is silcd/command.c.
1899 * Added channels topic announcements. Affected file is
1900 silcd/packet_receive.c and silcd/server.c.
1902 * Fixed the silc_server_send_notify_topic_set to really destine
1903 the packet to channel. Affected file silcd/packet_send.c.
1905 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1906 library. Affected file lib/silcclient/client_notify.c.
1908 * Added UMODE announcements. Affected file silcd/server.c.
1910 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1912 * Memory leak fixes in:
1914 lib/silcutil/silcsockconn.c
1915 lib/silcske/silcske.c
1916 lib/silcske/groups.c
1918 lib/silccrypt/silcpkcs.c
1919 lib/silccore/silccommand.c
1920 lib/silccore/silcidcache.c
1925 * ROBOdoc documented the lib/silcske/groups.h file and a
1926 bit changed the interface for better.
1928 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1930 * Update the client entry context in the ID cache after
1931 nick change. Affected file lib/silcclient/command.c.
1932 Fixes the CUMODE command when regaining founder privileges,
1933 and a little WHOIS problem.
1935 * Fixed silc_net_gethostbyname to correctly call the
1936 inet_ntop. Affected file lib/silcutil/silcnet.c.
1938 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1940 * Added IPv6 support checking to the configure.in.pre, added
1941 also --enable-ipv6 option to override the check. Affected
1942 file configure.in.pre.
1944 * The silc_thread_create now calls the start function
1945 directly if threads support is not compiled in. Removes
1946 ugly #ifdef's from generic code. Affected files are
1947 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1949 * Added silc_net_gethostby[name/addr]_async to asynchronously
1950 resolve. Affected files are lib/silcutil/silcnet.[ch].
1952 * Added support for rendering IPv6 based server, client and
1953 channel IDs. Affected file lib/silcutil/silcutil.c.
1955 * Added support for creating IPv6 based server IDs. Affected
1956 file is silcd/serverid.c.
1958 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1960 * Added silc_net_gethostby[addr/name] into the
1961 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1962 routines. Added silc_net_is_ip[4/6]. Affected file is
1963 lib/silcutil/unix/silcunixnet.c. All routines that take
1964 address as argument now supports both IPv4 and IPv6 addresses.
1966 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1968 * Fixed LIST command reply sending in server. Affected file
1971 * Server now sends the kicker's client ID in the KICK notify
1972 to the kicked client. Affected file silcd/command.c.
1974 * The client library now parses the kickers client ID and
1975 UI displays it. Affected files lib/silcclient/client_notify.c
1976 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1978 * Made all payload parsing function prototypes consistent.
1979 They all take now const unsigned char * and uint32 pair as
1980 the payload data instead of SilcBuffer. Changes all around
1981 the source tree. Other unsigned char* -> const unsigned char*
1982 changes around the tree as well.
1984 * Optimized SFTP client and server packet sending not to
1985 allocate new buffer for each packet but to recycle the
1986 first allocated buffer. Affected files are
1987 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1989 * Optimized the SFTP client to use SilcList instead of
1990 SilcDList for requests, because it is faster. Affected file
1991 is lib/silcsftp/sftp_client.c.
1993 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1994 into lib/silccore/silcid.[ch].
1996 Renamed silcpayload.[ch] into silcargument.[ch].
1998 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * If client entry is deleted with active key agreement
2001 session, abort the session.
2003 The silc_client_abort_key_agreement now calls the completion
2004 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2006 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2009 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2011 * Don't use __restrict in older GCC's. Affected file is
2012 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2014 * silc_net_localhost now attempts to reverse lookup the
2015 IP/hostname. Affected file lib/silcutil/silcnet.c.
2017 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2018 command. It can be used to gain founder privileges at
2019 the same time when joining the channel.
2021 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2022 kicker's client ID as well. Updated protocol specs.
2024 Defined that the server must send SILC_COMMAND_IDENTIFY
2025 command reply with error status to client who sent
2026 private message with invalid client ID.
2028 Updated the protocol specification.
2030 * Added silc_server_send_command_reply to send any
2031 command reply. Affected file silcd/packet_send.[ch].
2033 * Added silc_id_payload_encode_data to encode ID payload
2034 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2036 * The server now send IDENTIFY command reply with error
2037 status if client ID in private message is invalid. Affected
2038 file silcd/packet_receive.c.
2040 * Save the server key file with server's IP address in
2041 the filename instead of hostname. The affected file is
2042 irssi/src/silc/core/client_ops.c.
2044 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2049 * Added libtool support for compiling shared objects in
2050 lib/silcsim. Affected file configure.in.pre and
2051 lib/silcsim/Makefile.am. Original patch by cras.
2053 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * Pid file configuration, and server's config file fixes
2056 patch by toma. Updated CREDITS file.
2058 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * Fixed silc_client_channel_message to not try to decrypt
2061 the message twice if it resolved the destination client
2062 information. This could cause of dropping one channel
2063 message. Affected file lib/silcclient/client_channel.c.
2065 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2068 lib/silcclient/client.c. This function is used when the SILC
2069 Client is run under some other scheduler, or event loop or
2070 main loop. On GUI applications, for example this may be
2071 desired to used to run the client under the GUI application's
2072 main loop. Typically the GUI application would register an
2073 idle task that calls this function multiple times in a second
2074 to quickly process the SILC specific data.
2076 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2078 * Fixed silc_server_drop() for dropping the supplementary
2079 groups as well, this could cause a security hole on some
2082 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2087 * Write PID file after dropping privileges. Added -F option
2088 to run server on foreground. A patch by debolaz.
2089 Affected files silcd/server.c, silcd/silcd.c.
2091 * Fixed MOTD to return the MOTD file server name. Affected
2092 file silcd/command.c.

2095 Affected file irssi/src/silc/core/client_ops.c.
2097 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2099 * Fixed the silc_idcache_list_* routines to really support
2100 the dynamic list. Fixes a crash. Affected file is
2101 lib/silccore/silcidcache.c.
2103 * Fixed the LIST command reply to really call LIST command's
2104 pending callbacks. Affected file silcd/command_reply.c.
2106 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Update conn->local_entry->nickname after giving NICK
2109 command. Affected file lib/silcclient/command.c.
2111 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2113 * Added the [pid] option to the silcd configuration file
2115 Affected files: serverconfig.[ch] and silcd.c
2117 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2119 * Save fingerprint in WHOIS command reply in server.
2120 Affected file silcd/command_reply.c.
2122 * Fixed NICK commands pending callback registration.
2123 Affected file lib/silcclient/command.c.
2125 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2127 * Use ++server->cmd_ident when sending commands in server,
2128 instead of random number. Affected file silcd/command.c.
2130 * Fixed GETKEY command reply to call actually GETKEY pending
2131 command callbacks. Affected file silcd/command_reply.c.
2133 * A bit stricter check for nicknames. Check for same nickname
2134 in NICK command also. Affected file silcd/command.c.
2136 * Do not call INFO command everytime client ID changes, only
2137 during first connecting. Affected file lib/silcclient/client.c.
2139 * Set the new nickname only after successful command reply for
2140 NICK command is returned by server. Affected file
2141 lib/silcclient/command.c.
2143 * Remove nicknames from nicklist during server_signoff notify.
2144 Should fix /NAMES bit more. The affected file is
2145 irssi/src/silc/core/silc-channels.c.
2147 * Added `fingerprint' field to the SilcIDListData in the
2148 silcd/idlist.h to hold the fingerprint of the client's
2151 Send the fingerprint of the client's public key in WHOIS
2154 Affected files silcd/command.c, and silcd/idlist.[ch].
2156 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2157 create fingerprint from given data.
2159 * Show the fingerprint of the client's public key in WHOIS.
2160 Affected files irssi/src/module-formats.[ch] and
2161 irssi/src/silc/core/client_ops.c.
2163 * Format the multiple same nicknames also during JOIN and
2164 NICK_CHANGE notifys. Affected file is
2165 lib/silcclient/client_notify.c.
2167 * Do not print error on screen for invalid private message
2168 payload since it can come if someone is sending private
2169 messages with wrong key. Affected file
2170 lib/silccore/silcprivate.c.
2172 * Fixed multiple concurrent /PING crash. Affected file
2173 lib/silcclient/command.c.
2175 * Changed the wrong ID encoding. All IP addresses must be
2176 in MSB first order in encoded format. They were encoded
2177 wrong and was in LSB format. Affected files are
2178 silcd/serverid.c, lib/silcutil/silcutil.c.
2180 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2182 * Call the `connect' client operation through the scheduler
2183 in case of error. Affected file lib/silcclient/client.c.
2185 * Call the `failure' client operation even if the error
2186 occurred locally during a protocol. Affected file is
2187 lib/silcclient/protocol.c.
2189 * Added support of sending LIST command to router from normal
2190 server. This way normal server can get list of all channels
2191 in the network too. Fixed the channel list sending in the
2192 server too. Affected files are silcd/command.c, and
2193 silcd/command_reply.[ch].
2195 * Added silc_server_update_channels_by_server and
2196 silc_server_remove_channels_by_server. They are used during
2197 disconnection of primary router and in backup router protocol.
2198 Affected file silcd/server_util.[ch], silcd/server.c and
2199 silcd/server_backup.c.
2201 * Fixed channel adding to global list in IDENTIFY command
2202 reply in server. Affected file silcd/command_reply.c.
2204 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2206 * If the incoming packet type is REKEY or REKEY_DONE process
2207 that packet always synchronously. Fixes yet another MAC
2208 failed error on slow (dialup) connections. Affected file
2209 lib/silcclient/client.c and silcd/server.c.
2211 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2213 * Call check_version SKE callback for initiator too. Affected
2214 file lib/silcske/silcske.c.
2216 * Implemented fix for security hole found in the SKE that was
2217 fixed in the specification few days back; the initiator's
2218 public key is now added to the HASH value computation.
2219 Added backwards support for the old way of doing it too, for
2220 old clients and old servers. Affected file is
2221 lib/silcske/silcske.c.
2223 * Enabled mutual authentication by default in SKE. If initiator
2224 is not providing mutual authentication the responder will
2225 force it. This will provide the proof of posession of the
2226 private key for responder. The affected files are
2227 lib/silcclient/protocol.c and silcd/protocol.c.
2229 * Do not cache anymore the server's public key during SKE.
2230 We do mutual authentication so the proof of posession of
2231 private key is done, and if the server is authenticated in
2232 conn auth protocol with public key we must have the public
2233 key already. Affected file silcd/protocol.c.
2235 * Added new global debug variable: silc_debug_hexdump. If
2236 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2237 file lib/silcutil/silclog.[ch].
2239 * Fixed compilation warning due to char * -> const char *.
2240 Affected files lib/silcutil/silcnet.h, and
2241 lib/silccore/silcauth.[ch].
2243 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2245 * Fixed CMODE command when new channel key was created. If
2246 the creation failed the old key was removed. Next time giving
2247 same command would crash the server since the old key was
2248 freed already. Affected file silcd/command.c.
2250 * Fixed the silc_server_announce_get_channels to not crash
2251 on reconnect. Affected file silcd/server.c.
2253 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2255 * Added silc_log_set_debug_string function to set a regex
2256 string to match for debug output. Only the function names,
2257 or filenames matching the given debug string is actually
2258 printed. This way it is possible to filter out those debug
2259 strings that user is not interested in.
2261 Fixed a bug in silc_string_regexify.
2263 Affected files lib/silcutil/silclog.[ch], and
2264 lib/silcutil/unix/silcunixutil.c.
2266 * Changed the -d options in both server and Irssi SILC client
2267 to take the debug string as argument. Affected files
2268 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2270 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2272 * Added silc_hash_babbleprint to create a Bubble Babble
2273 Encoded fingerprint. The encoding is developed by Antti
2274 Huima (draft-huima-babble-01.txt), and it creates human
2275 readable strings out of binary data. Affected file
2276 lib/silccrypt/silchash.[ch].
2278 * Print the babble print now in addition of fingerprint as well
2279 in Irssi SILC client. Affected files are
2280 irssi/src/fe-common/silc/module-formats.[ch],
2281 irssi/src/fe-common/silc/core/client_ops.c.
2283 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2285 * Fixed a security problem found in SKE. The initiator's
2286 public key too is now added to the HASH hash value creation
2287 which is signed by the responder to create the SIGN value.
2288 This will prevent anyone in the middle to lie to the responder
2289 about the initiator's public key. If this is done now, the
2290 man in the middle will get caught. Updated the protocol
2293 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2295 * Better installation directory handling. Configure module
2296 paths and other paths automatically to example_silc* files
2297 in doc/. A patch by toma.
2299 * Fixed compiler warning from MPI library, and from SILC RNG.
2302 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2303 It can be configured with ./configure. A patch by toma.
2305 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Find correct make to use in prepare-clean. A patch by
2308 toma. Affected file prepare-clean.
2310 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2312 * Added irssi variables use_auto_addr, auto_bind_ip,
2313 auto_bind_port and auto_public_ip.
2315 * Changed the interface for silc_client_send_key_agreement
2316 in lib/silcclient/silcapi.h
2320 irssi/src/silc/core/silc-core.c
2322 lib/silcclient/silcapi.h
2323 irssi/src/silc/core/silc-channels.c
2324 lib/silcclient/client_keyagr.c
2327 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2329 * Added silc_pkcs_public_key_compare to compare two
2330 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2332 * Check that the client who set the founder mode on the
2333 channel is the same client that is giving the founder
2334 mode to itself. It is done by comparing the saved public
2335 key (it is saved even in the authentication is passphrase).
2336 Affected file silcd/command.c.
2338 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * Do not process packet for disconnected socket connection.
2341 Affected file lib/silccore/silcpacket.c.
2343 * Process the DISCONNECT packet through scheduler in the
2344 client library. Affected file lib/silcclient/client.c.
2346 * Fixed the silc_client_packet_parse to not to increase
2347 the packet sequence number if the conn->sock and the
2348 current socket connection is not same. This can happen
2349 for example during key agreement when the conn includes
2350 multiple socket connections (listeners). Affected file
2351 lib/silcclient/client.c.
2353 * The sender of the file transfer request now provides also
2354 the pointer (listener) for the key exchange protocol. If
2355 the listener cannot be created then it sends empty key
2356 agreement and lets the receiver provide the listener.
2358 Added `local_ip' and `local_port' arguments to the
2359 silc_client_file_send. If they are provided they are used,
2360 if not then it will attempt to find local IP address, if
2361 not found or bind fails then the remote client will provide
2364 Affected files are lib/silcclient/client_ftp.c and
2365 lib/silcclient/silcapi.h.
2367 * Extended the FILE SEND command to support defining the
2368 local IP and port for key exchange listener. They are
2369 optional. Affected file irssi/src/silc/core/silc-servers.c.
2371 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2373 * Defined to WHOIS command reply the sending of fingerprint
2374 of the client's public key (if the proof of posession of the
2375 corresponding private key is verified by the server).
2376 Updated to the protocol specification.
2378 * Added support of receiving the client's public key's
2379 fingerprint in command reply in client library. Affected
2380 file is lib/silcclient/command_reply.c, and
2381 lib/silcclient/idlist.[ch].
2383 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2385 * Do not send over 128 chars long nickname to the server
2386 in NICK command. Affected file lib/silcclient/command.c.
2388 * Do not send over 256 chars long channel names to the server
2389 in JOIN command. Affected file lib/silcclient/command.c.
2391 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * Assure that silc_server_close_connection cannot be called
2394 twice for same socket context. Affected file is
2397 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Send error message to application if opening file for
2400 writing during file transfer fails. Affected file is
2401 lib/silcclient/client_ftp.c.
2403 Remove all file transfer sessions for a client that we're
2404 removing from ID cache.
2406 Affected file is lib/silcclient/client_ftp.c.
2408 * Fixed silc_net_addr2bin to return correct address. Affected
2409 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2411 * Fixed file transfer session removing on signoff notify.
2412 Affected file irssi/src/silc/core/silc-servers.c.
2414 * Added the SilcClientFileError to be returned in the monitor
2415 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2416 Affected file lib/silcclient/silcapi.h.
2418 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2420 * Fixed a crash in silc_client_ftp_free_sessions and
2421 silc_client_ftp_session_free_client. Affected file
2422 lib/silcclient/client_ftp.c.
2424 * Added `disabled' field in the SilcChannelEntry in the server
2425 to indicate if the server entry is disabled. Affected file
2426 silcd/idlist.h, silcd/command[_reply].c.

2429 started. Affected file silcd/silcd.c.
2431 * Added silc_server_packet_send_clients to send a packet to
2432 the provided table of client entries. Affected file
2433 silcd/packet_send.[ch].
2435 * Fixed a crash in client resolving in client_prvmsg.c in
2436 client library. Affected file lib/silcclient/client_prvmsg.c.
2438 * Do not actually remove the client directly from ID cache
2439 during SERVER_SIGNOFF, but invalidate it. This way we
2440 preserve the WHOWAS info for the client. Affected file
2441 silcd/server_util.c.
2443 * Fixed SERVER_SIGNOFF notify handling in the server. The
2444 server is now able to process incoming SERVER_SIGNOFF notify
2445 for a server that it doesn't even know about. It will remove
2446 the clients provided in the notify. Affected file
2447 silcd/packet_receive.c.
2449 * Check for partial packet in data queue after every packet that
2450 was found from the queue. Return and wait for more data if
2451 there is partial data in queue. Affected file is
2452 lib/silccore/silcpacket.c.
2454 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2456 * Added SilcClietFileError enum to indicate error in
2457 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2458 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2459 Affected files lib/silcclient/silcapi.h and
2460 lib/silcclient/client_ftp.c.
2462 * Check that newsize in silc_buffer_realloc is larger than
2463 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2465 * Added better monitor of file transfers. It now monitors
2466 key agreement protocol during the file transfer too. Added
2467 error reporting too. Affected files
2468 irssi/src/silc/core/silc-servers.c,
2469 irssi/src/fe-common/silc/module-formats.[ch].
2471 * Wrote a help file for FILE command.
2473 * Added silc_rng_global_get_byte_fast to get not-so-secure
2474 random data as fast as possible. Random data is read from
2475 /dev/urandom if available and from the SILC RNG if not
2476 available. It is used in padding generation. Affected file
2477 lib/silccrypt/silcrng.[ch].
2479 * All packets in client library are now processed synchronously.
2480 Optimized packet processing a lot. Affected file
2481 lib/silcclient/client.c.
2483 * All server connection packets are processing synchronously
2484 now in server, to optimize packet processing. Affected file
2487 * Include files are installed now only in Toolkit distribution
2488 if make install is given. Affected files: all Makefile.am's.
2490 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2492 * Assure that silc_client_notify_by_server_resolve does not
2493 resolve the client information multiple times. If it cannot
2494 be found by the first it cannot be found at all. Affected
2495 file lib/silcclient/client_notify.c.
2497 * Fixed WHOWAS command reply calling. Affected file
2498 lib/silcclient/command_reply.c.
2500 * Removed all references to silc_idlist_get_client from the
2501 Irssi SILC client since that call is internal call used by
2502 the library. The Irssi SILC client will use now client
2503 retrieval functions found in silcapi.h.
2505 * Fixed a bug in resolving nickname info before sending
2506 private message. It used freed memory. Affected file
2507 irssi/src/silc/core/silc-servers.c.
2509 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * Assure my_channels statistics cannot go negative in server.
2512 Affected files silcd/server.c, silcd/server_util.c.
2514 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2524 lib/sftp/sftp_fs_memory.c.
2526 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2528 * Added silc_net_localip to return local host's IP address.
2529 Affected file lib/silcutil/silcnet.[ch].
2531 * If key exchange or rekey protocol is active for a connection
2532 parse all packets syncronously since there might be packets
2533 in packet queue that we are not able to process without first
2534 processing packets before them. Affected file silcd/server,
2535 lib/silcclient/client.c.
2537 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2538 whether library should continue processing the packet.
2539 Affected file lib/silccore/silcpacket.h.
2541 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2570 lib/silcutil/silcutil.[ch].
2572 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2574 * Resolve the client info when received private message or
2575 channel message for a client which nickname we don't know.
2576 Affected files lib/silcclient/client_prvmsg.c and

2589 Make sure also that USERS command reply does not resolve
2590 twice information. Affected file is
2591 lib/silcclient/command_reply.c.
2593 Make sure that silc_client_get_clients_by_list does not
2594 resolve twice same information.
2596 * Check for valid client->id in the silc_server_free_client_data.
2597 Affected file silcd/server.c.
2599 * Fixed /GETKEY nick@server not to crash if the server entry
2600 is not found. Affected file lib/silcclient/command.c.
2602 * Fixed the silc_server_check_cmode_rights to check the

2608 Affected file silcd/command.c.
2610 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2612 * Call the silc_server_udpate_servers_by_server in the
2613 primary router that comes back online in the backup resuming
2614 protocol. Otherwise it routes packets wrong. Affected file
2615 silcd/server_util.[ch], silcd/server_backup.c.
2617 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2619 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2620 lib/silcutil/silcbuffmt.[ch].
2622 * Redefined the SILC packet header to include the padding
2623 length. Affected file lib/silccore/silcpacket.[ch].
2625 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2626 length for maximum padding up to 128 bytes). Affected
2627 file lib/silccore/silcpacket.h.
2629 * Removed all backwards support for old 0.5.x MAC thingies.
2630 The SILC packet header change makes it impossible to be
2631 backwards compatible.
2633 * Send the ENDING packet with timeout in the backup resuming
2634 protocol. This is to assure that all routers has connected
2635 to the primary router. Affected file silcd/server_backup.c.
2637 * Changed the RNG to take the first IV from random data. It
2638 used to take it from zero actually. Changed the RNG also
2639 to use /dev/urandom during session. /dev/random is used
2640 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2642 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2644 * Changed the SILC packet header to have the first two bytes
2645 (the packet length) encrypted. Affected files aroung the
2646 code tree, lib/silccore/silcpacket.[ch]. Removed the
2647 SilcPacketCheckDecrypt callback. It is not needed anymore
2648 since the silc_packet_receive_process will determine now
2649 whether the packet is normal or special.
2651 * Implemented the unidirectional MAC keys. Affected files
2652 lib/silcske/silcske.c, silcd/protocol.c and
2653 lib/silcclient/protocol.c.
2655 * Implemented the packet sequence number to the MAC computation.
2656 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2657 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2658 lib/silcclient/protocol.c.
2660 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2662 * Allow backup router to announce servers. All servers
2663 announced by backup router are added to the global list
2664 automatically. Update hte server's socket to our primary
2665 router also when backup router announces a server.
2666 Affected file silcd/packet_receive.c.
2668 * Do not update the client->router in the function
2669 silc_server_udpate_clients_by_server if the client is on
2670 global list. We might fail to find any specific server
2671 for locally connected clients and local cell clients. They
2672 should still use the `from' and not `to' as client->router.
2673 This fixes backup router resuming protocol. Affected file
2674 silcd/server_util.c.
2676 * Decrease channel statistics count only if the channel
2677 deletion worked. Affected files are silcd/server.c and
2678 silcd/server_util.c.
2680 * Added silc_server_update_servers_by_server to update origin
2681 of all server entries. Used during backup router protocol.
2682 Affected files silcd/server_util.[ch], silcd/server.c. and
2683 silcd/backup_router.c.
2685 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2686 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2687 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2688 lib/silccrypt/silchmac.c.
2690 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2692 * Assure that router cannot reroute the same channel message
2693 to the sender. Affected file silcd/packet_receive.c.
2695 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2697 * Made better checks that the channel message is not sent
2698 to the router it came from. Affected file is
2699 silcd/packet_send.c. Fixed memory leak too.
2701 * Announce informations for incoming router connection, but
2702 only after checking if it is replaced by backup router.
2703 Affected file silcd/packet_receive.c.
2705 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Fixed the backup resuming protocol to work in multiple
2708 router environment. Affected file silcd/server_backup.c.
2710 * Route packet only to one router in the function
2711 silc_server_packet_send_to_channel. Affected file is
2712 silcd/packet_send.c.
2714 * Fixed silc_server_send_notify_dest to set the broadcast
2715 flag. Fixed the silc_server_send_notify_topic to actually
2716 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2717 Affected file silcd/packet_send.c.
2719 * Changed the SFTP Filesystem interface. Changed the
2720 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2721 the filesystem operation function. The SilcSFTPFilesystem
2722 is now a context that is allocated by all filesystem allocation
2723 functions and it already includes the operations structure
2724 and filesystem specific context. It is given as argument
2725 now to the silc_sftp_server_start. This made the interface
2726 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2727 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2729 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * Changed the backup router adding and getting interfaces
2732 in the server. The router that will be replaced by the
2733 specified backup router is now sent as argument. Affected
2734 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2737 * Added silc_net_addr2bin_ne to return the binary form of
2738 the IP address in network byte order. Affected files
2739 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2741 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Check for existing server ID in silc_server_new_server
2744 and in silc_server_connect_to_router_final and remove the
2745 old entry if it exists. Affected file silcd/packet_receive.c,
2748 * Send the channel message always to only one router, either
2749 in upstream or downstream. Affected file is
2750 silcd/packet_send.c.
2752 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2754 * Wrote the definition of the backup resuming protocol to the
2755 protocol specification.
2757 * Removed one redundant channel key generation from normal
2758 server during joining procedure. Removed one redundant
2759 channel key sending from server to router during joining
2760 procedure. Affected file silcd/command.c.
2762 * Made minor bugfixes to the backup router resuming protocol.
2763 Affected file silcd/server_backup.c, server.c.
2765 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Added --disable-asm configuration option. Affected files
2768 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2771 * Implemented the backup resuming protocol that is used to
2772 resume the primary router position in the cell after the
2773 primary router comes back online. Affected files
2774 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2775 and silcd/server_util.[ch].
2777 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * Sleep two (2) seconds after sending QUIT command to server.
2780 Affected file lib/silcclient/command.c.
2782 * Assure that if outgoing data buffer is pending do not force
2783 send any data. Affected file silcd/packet_send.c.
2785 * Assure that if outgoing data buffer is pending do not force
2786 send any data. Affected file lib/silcclient/client.c.
2788 * Implemented the backup router support when the primary router
2789 goes down. The servers and routers can now use the backup
2790 router as new primary router without loosing connectivity.
2792 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2794 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2795 in the server to indicate disabled entry. All data read
2796 from the connection will be ignored and no data is sent
2797 for entry that is disabled. Affected files are
2798 silcd/idlist.h, silcd/server.c.
2800 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2802 * Created SFTP client and server test programs in the
2803 lib/silcsftp/tests directory.
2805 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Implemented memory filesystem (virtual filesystem) for
2808 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2811 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2813 * Implemented the SFTP (SSH File Transfer Protocol) to the
2814 lib/silcsftp. It includes SFTP client and SFTP server
2817 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2819 * Moved lib/silccore/silcprotocol.[ch] to the
2820 lib/silcutil library.
2822 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2823 take variable argument list pointer as argument. Affected
2824 file lib/silcutil/silcbuffmt.[ch].
2826 * Added silc_buffer_set function that is used to set data
2827 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2828 Affected file lib/silcutil/silcbuffer.h.
2830 * Changed various routines in the core library to use the new
2831 silc_buffer_set instead of allocating new buffer only for
2834 * Added 64-bit value formatting and unformatting support to the
2835 silc_buffer_[un]format routines. Affected file is
2836 lib/silcutil/silcbuffmt.[ch].
2838 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2839 to includes/bitmove.h.
2841 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2843 * Fixed channel user mode saving in client library. Affected
2844 file lib/silcclient/command[_reply].c.
2846 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * Defined the file transfer to the SILC Protocol. Added
2849 new packet type SILC_PACKET_FTP and defined File Transfer
2850 Payload. The mandatory file transfer protocol is SFTP
2851 (SSH File Transfer Protocol). Affected file in addition
2852 of the internet draft is lib/silccore/silcpacket.h.
2854 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2855 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2856 is used as part of backup router protocol when the primary
2857 router of the cell is back online and wishes to resume
2858 the position as primary router.
2860 * Redefined the MAC generation keys in the protocol. The
2861 same key is not used anymore in both direction. Both
2862 direction will now use different keys for sending and
2863 receiving. This fixes a potential security flaw. This
2864 change causes incompatibilities in the protocol.
2866 * Redefined also the MAC computation from the packet.
2867 An packet sequence number is now added to the MAC
2868 computation. This prevents possible replay attacks against
2869 the protocol. This change too causes incompatibilities
2872 Added `sequence' field to the SilcPacketContext to hold
2873 the current sequence number for the packet.
2875 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2877 * Added `created' field to the SilcIDListData in the file
2878 silcd/idlist.h to indicate the time when the entry was
2881 * Added `created' field to the SilcChannelEntry too. Affected
2882 file silcd/idlist.h.
2884 * Added `creation_time' aguments to all the announcement functions
2885 in the server. If it is provided then only the entries that
2886 was created after the provided time frame are actually
2887 announced. Affected file silcd/server.[ch].
2889 * The protocol says that the Channel ID's IP address must be
2890 based on the router's IP address. Added check for this in
2891 the silc_server_new_channel when processing incoming New Channel
2892 Payload. Affected file silcd/packet_receive.c.
2894 * Print out the correct version with --version in SILC client.
2895 Affected file irssi/src/silc/core/silc-core.c.
2897 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2899 * Fixed WHOWAS command to check for completnes of the client
2900 entry always, not just when the command is coming from client.
2901 Affected file silcd/command.c.
2903 * Added new function silc_server_packet_queue_purge to purge the
2904 outgoing data queue to the network. After the function returns
2905 it is guaranteed that the outgoing packet queue is empty.
2906 Affected file silcd/packet_send.[ch].
2908 * Purge the outgoing packet queue in the rekey protocol's final
2909 callback to assure that all rekey packets go to the network
2910 before quitting the protocol. Affected file silcd/server.c.
2912 * Added silc_client_packet_queue_parse as similar function as
2913 in server to the client library. The affected file is
2914 lib/silcclient/client.c.
2916 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Splitted silcd/server.c and created silcd/server_util.[ch]
2919 for utility functions.
2921 * Added new socket flag SILC_SF_DISABLED to indicate that the
2922 connection is open but nothing can be sent to or received from
2923 the connection. Affected file lib/silcutil/silsockconn.[ch].
2924 The checking for disabled socket is checked in the low level
2925 silc_socket_write and silc_socket_read functions.
2927 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Allow only nicknames and channel names that fits into the
2930 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2932 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * When processing JOIN command reply in server check that if
2935 the channel exists in our global list we'll move it the local
2936 list. Affected file silcd/command_reply.c.
2938 * Fixed the check whether client is joined on the channel already
2939 in JOIN command. Affected file lib/silcclient/command.c.
2941 * Fixed the JOIN command reply to check whether the channel
2942 already exists. Affected file lib/silcclient/command_reply.c.
2944 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Added silc_ske_status_string to map the SKE error numbers
2947 to readable strings. The affected files are
2948 lib/silcske/silcske[_status].[ch].
2950 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2952 * Do not show the private channels on the WHOIS channel list
2953 as it is not allowed by the protocol. The affected file is
2956 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Assure that the packet length digged from the actual packet
2959 is something sensible in the silc_packet_decrypt_rest_special
2960 in lib/silccrypt/silcpacket.c.
2962 * Free and NULL the allocated pointer in silc_hmac_alloc if
2963 the HMAC allocation fails. The affected file is
2964 lib/silccrypt/silchmac.c.
2966 * Print the selected security properties to the log files in
2967 the server. Affected file silcd/protocol.c.
2969 * Add SKE's reference counter even if calling the completion
2970 callback manually. Otherwise it goes negative, although it
2971 does not cause any problems. The affected file is
2972 lib/silcske/silcske.c.
2974 * Remove the client entry with short timeout after giving the
2975 KILL command. Affected file lib/silcclient/command.c.
2977 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2978 case all found clients are already disconnected (WHOWAS would
2979 found them) in the server. Affected file silcd/command.c.
2981 * Update the last_receive (time of last data received) to be
2982 updated only when received private or channel message so that
2983 the idle time showed in WHOIS makes more sense.
2985 * Added boolean field `valid' in to the SilcClientEntry in the
2986 client library to indicate whether the entry is valid or not.
2987 This fixes the nickname change bug on channel when changing
2988 the nickname to be same than the old (like nick to Nick) the
2989 nickname formatter doesn't set the new nick anymore to Nick@host.
2990 Affected file lib/silcclient/idlist.[ch].
2992 * Now actually fixed the nickname changing on disconnection.
2993 Added new function silc_change_nick to the Irssi SILC Client.
2994 Affected file irssi/src/silc/core/client_ops.c,
2995 irssi/src/silc/core/silc-nicklist.[ch].
2997 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Check that the public key exists in the GETKEY command before
3000 trying to encode it. Affected file silcd/command.c.
3002 * Print some notifications on received public keys with GETKEY
3003 command in the Irssi SILC Client. Affected files are
3004 irssi/src/fe-common/silc/module-formats.[ch],
3005 irssi/src/silc/core/client_ops.c.
3007 * Use IDENTIFY command to resolve the server information in the
3008 GETKEY command instead of INFO command. Affected file
3009 lib/silcclient/command.c.
3011 * All command reply functions in the client library now calls
3012 the pending command reply callbacks even if an error has
3013 occurred. The server has done this a long time and now it was
3014 time to move the client library to this as well. Now all
3015 errors can be delivered back to the pending command reply
3016 callbacks if necessary. Affected files are
3017 lib/silcclient/command[_reply].[ch].
3019 * Change the nickname on disconnection back to the username
3020 because in reconnect the server will enforce it to it anyway.
3021 Affected file irssi/src/silc/core/silc-servers.c.
3023 * Fixed a config file parsing bug in the Irssi SILC client.
3024 Affected file irssi/src/silc/core/clientconfig.c.
3026 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3028 * When printing the channel mode on JOIN, verify that the
3029 channel key and channel's HMAC are valid. Affected file
3030 irssi/src/silc/core/client_ops.c.
3032 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3034 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3035 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3036 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3038 * Removed channel key rekey task deleting from the function
3039 silc_server_save_channel_key. Affected file silcd/server.c.
3040 Added explicit timeout task context instead that is used to
3041 delete the task if we are registering a new task before the
3042 new task has elapsed.
3044 * When channel key rekey occurs the client library now saves
3045 the old channel key for a short period of time (10 seconds) and
3046 is able to use it in case some is still sending channel
3047 messages encrypted with the old key after the rekey. Affected
3048 file lib/silcclient/[idlist.h|client_channel.c].
3050 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3052 * Added check to the silc_server_new_id_real to not accept
3053 new ID if it is the sender's own ID. Affected file is
3054 silcd/packet_receive.c.
3056 * Assure that we do not announce ourself or the one we've
3057 sending our announcements when we're router and are announcing
3058 servers to our primary router. Affected file silcd/server.c.
3060 * Fixed silc_server_command_identify_check_client to assemble
3061 correct WHOIS packet. It send corrupted WHOIS packet and
3062 caused problem with router to router connections. Affected
3063 file silcd/command.c.
3065 Fixed also silc_server_command_whois_check the same way
3066 as for the IDENTIFY command.
3068 * Added new SilcIDListStatus to the server in the SilcIDListData
3069 structure. The status now includes the current status of
3070 the entry (like registered, resolved etc.). Affected file
3071 silcd/idlist.[ch]. Defined a bunch of different status types
3072 as well. This replaced the old boolean registered field as well.
3074 Added resolve_cmd_ident field to the SilcClientEntry structure
3075 too so that if the entry is for example being resolved so
3076 another command may attach to the same pending command reply
3077 without requiring to resolve the same entry again. This concept
3078 should optimize the WHOIS and the IDENTIFY resolving under
3079 heavy load by taking away unnecessary resolving for entries
3080 that are being resolved already.
3082 Added support for adding multiple pending commands for one
3083 command idenfier. Affected file silcd/command[_reply].[ch].
3085 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3086 before deleting the data. Otherwise the hash table will have
3087 freed data in comparison functions. Affected file is
3088 silcd/command_reply.c.
3090 * Fixed silc_idlist_replace_client_id to add the new entry to
3091 the cache with NULL nickname. Otherwise there will be invalid
3092 memory as the nickname after the nickname is freed. Affected
3093 file silcd/packet_receive.c.
3095 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3096 saved into wrong slots because the previous number of entries
3097 was not taken into account. Affected file silcd/idlist.c.
3098 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3100 * If we are router and we receive JOIN notify to a channel that
3101 does not have any users then notified client is marked as the
3102 channel founder, as it is it. The affected file is
3103 silcd/packet_receive.c
3105 * Added to the extended hash table API's table_del_*ext functions
3106 the destructor as argument too, so that the caller can decide
3107 which destructor to use or whether to use destructor at all.
3108 Affected file lib/silcutil/silchashtable.[ch].
3110 * Fixed ID Cache purging. It actually deleted the entries from
3111 the hash table after the data was freed. The hash table ended
3112 up comparing freed memory. The affected file is
3113 lib/silccore/silcidcache.c.
3115 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3117 * Fixed Irssi SILC client's KILL command's HELP syntax.
3119 * The USERS command now resolves the detailed user information
3120 if the userinfo field is missing. Affected file is
3121 lib/silcclient/command_reply.c.
3123 * Do not print error in silc_file_read if the read file does
3124 not exist. Just silently return NULL. Affected file is
3125 lib/silcutil/silcutil.c.
3127 * Fixed the silc_log_output to not wine about NULL filename
3128 and to not create some bogus " " filename. Affected file is
3129 lib/silcutil/silclog.c.
3131 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Fixed various printing bugs on the user interface in the
3134 Irssi SILC Client. Minor changes that were forgotten from
3137 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3139 * Fixed the configure.in.pre and the compilation and distribution
3140 environment to support the new autoconf 2.52. That version is
3141 now required to compile the CVS trunk.
3143 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3146 to generally parse user@fqdn format strings. Affected file
3147 lib/silcutil/silcutil.c.
3149 * Added nickname_format and nickname_force_format fields to the
3150 SilcClientParams structure. The first one defines the format
3151 for the nicknames that the library will enforce if the receives
3152 multiple same nicknames. The second one is boolean value and
3153 can be used to force the library to always enforce the format
3154 to the nicknames regardles whether there are multiple nicknames
3155 or not. This configurable formatting was employed to flexibly
3156 support accessing multiple nicknames from the user interface.
3157 The userinterface can now set the nicknames to what ever format
3158 they prefer. Affected file lib/silcclient/silcapi.h.
3160 Added function silc_client_nickname_format to the file
3161 lib/silcclient/idlist.c. It performs the nickname formatting.
3163 Added new field `hostname´ to the SilcClientEntry context.
3164 It holds the hostname of the client. Affected file is
3165 lib/silcclient/idlist.h.
3167 * Irssi SILC Client sets the nicknames in nick@hostn format.
3168 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3169 irssi/src/silc/core/silc-core.c.
3171 The WHOIS printing now also shows both the real nickname and
3172 the formatted nickname so that user knows how to access the
3173 user if there are multiple same nicknames cached. Affected
3174 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3175 printing formatting too to take the hostname now as a separate
3176 argument. The Affected file is
3177 irssi/src/fe-common/silc/modules-formats.[ch].
3179 * Changed the silc_client_get_clients_local to accept the formatted
3180 nickname as argument. It accepts the real nickname too but the
3181 formatted nickname can be used to find the true entry from
3182 multiple entries. Affected file lib/silcclient/silcapi.h and
3183 lib/silcclient/idlist.c.
3185 * Added nickname_format_parse field to the SilcClientParams.
3186 It is a callback function provided by the application to parse
3187 the nickname out of the formatted nickname string. The library
3188 calls it to get the nickname from the formatted string. Since
3189 the application generally knows better the format of the nickname
3190 string it parses it instead of the library, even though library
3191 encodes the formatted string. If the callback function is not
3192 provided then the library will use the string as is. The
3193 affected file is lib/silcclient/silcapi.h.
3195 * All the nickname strings passed to the client library in
3196 commands are now expected to be formatted nickname strings.
3197 If the command does not support the formatted nickname string
3198 it will assume that the sent string is the actual nickname.
3199 Affected file lib/silcclient/command.c.
3201 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3203 * Added public key authentication support to OPER and SILCOPER
3204 commands in the client library. Affected file is
3205 lib/silcclient/command.c.
3207 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3209 * Changed the get_auth_methdod client operation to be asynchronous.
3210 It can be async if the application resolves the authentication
3211 method from the server during the negotiation. Added new
3212 SilcGetAuthMeth completion callback that the application will
3213 call after resolving the authentication method.
3215 Added function silc_client_request_authentication_method that
3216 the application can use to resolve the authentication method
3217 from the server. Added also SilcConnectionAuthRequest callback
3218 that the library will call after the server has replied. The
3219 application can call this function if it does not know the
3220 current authentication method.
3222 Affected files are lib/silcclient/client.c and
3223 lib/silcclient/silcapi.h.
3225 * The Irssi SILC client now automatically resolves the authentication
3226 method incase any configuration information is not present (and
3227 currently there never is). The affected file is
3228 irssi/src/silc/core/client_ops.c.
3230 * Fixed public key authentication from the client library.
3231 Affected file lib/silcclient/protocol.c. Changed also the
3232 protocol specification about the public key authentication in
3233 the connection authentication protocol. The actual data to be
3234 signed is now computed with a hash function before signing.
3236 * Fixed the public key authentication from the server as well.
3237 Affected file silcd/protocol.c.
3239 * Removed the mlock()'s from the memory allocation routines.
3240 Affected file lib/silcutil/silcmemory.c. The ./configure does
3241 not check anymore for the mlock(). Affected file is
3244 * Fixed USERS command in server to allow the execution of the
3245 command for private and secret channels if the client sending
3246 the command is on the channel. Affected file silcd/command.c.
3248 * Fixed silc_client_get_clients_local to return the clients
3249 count correctly. It could return wrong value. Affected file
3250 lib/silcclient/idlist.c.
3252 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3254 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3255 types. The assembler optimizations seemed not to like 64-bit
3256 data types. The assmebler optimizations thus are now enabled
3257 also for BSD systems as opposed to only enable them for Linux.
3259 * Do not check for threads at all on BSD systems. Affected
3260 file configure.in.pre.
3262 * Removed -n and -h options from the Irssi SILC Client since
3263 they are not used in silc.
3265 * Fixed the prime generation to assure that the first digit
3266 of the generated random number is not zero since our conversion
3267 routines does not like number strings that starts with zero
3268 digit. If zero digit is seen the random number is regenerated.
3269 This caused some corrupted RSA keys when the zero first digit
3270 was met. Affected file lib/silcmath/silcprimegen.c.
3272 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3274 * Fixed WIN32 configuration in the ./configure script.
3275 Fixed to include xti.h on environments that has it.
3276 Patches by Carsten Ilchmann and andrew.
3278 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3280 * Changed the silc_id_create_client_id to be collision
3281 resistant. It is now assured that there cannot be created
3282 two same client ID's. I suspect that some weird bugs in
3283 the server were actually caused by duplicate Client IDs.
3284 Affected file silcd/serverid.[ch]. A router receiving
3285 new ID now also assures and informs the sending server
3286 if the ID caused collision.
3288 * Changed the silc_id_create_channel_id to also assure that
3289 there are no collisions.
3291 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Statement about ignoring the Mutual Authentication flag when
3294 performing rekey with PFS was a bit misleading. It is ignored
3295 if it was set in the initial negotiation, it cannot be even
3296 set in the rekey. Fixed in the ke-auth draft. Started the
3297 new versions of the protocol drafts in the doc/.
3299 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3301 * Fixed a bug in silc_client_command_identify_save when saving
3302 new channel information. The channel name was no duplicated
3303 and caused crash on exit. Affected file is
3304 lib/silcclient/command_reply.c.
3306 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3308 * Fixed the getkey command handling in the server. Send just
3309 empty OK reply to the sender if the key could not be fetched
3310 (but everything else was ok, like the key just was not available).
3311 Changed the public key parameter to optional in the protocol
3312 specs so that empty OK reply can be sent. Affected file
3315 Added a message to Irssi SILC client to tell to user if the
3316 server did not return a public key.
3318 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3320 * Fixed a channel key regeneration bug. It registered new
3321 timeout tasks exponentially until all system resources were
3322 used. Affected file silcd/server.c.
3324 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3326 * Added the SILC Document generator to the scripts/silcdoc.
3327 It can be used to generate the Toolkit Reference Manual out
3328 of the source tree. Internally it will also use the RoboDoc
3329 generator now imported in util/robodoc.
3331 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3333 * Added couple of return's in rekey protocol if error orccurred
3334 during the protocol. The execution must be terminated.
3335 Affected file silcd/protocol.c. Also, terminate the protocol
3336 always with timeout.
3338 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3340 * The client's Client ID was created initally from the wrong
3341 nickname (it could have been in format nick@host) in the
3342 silc_server_new_client. Affected file silcd/packet_receive.c
3344 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3346 * Added some SILC_LOG_ERROR's to various error conditions
3347 if client could not be added to ID cache. Affected files
3348 silcd/packet_receive.c and silcd/server.c.
3350 * When client's sock->user_data is freed, NULL also the
3351 client->router and client->connection pointers. Added check
3352 for these pointers being NULL to various places around the
3353 code. Affected file silcd/server.c.
3355 * Added client->data.registered == TRUE checks to various
3356 places around the code to assure that unregistered client's
3357 are not handled when it is not allowed. Affected file
3360 * Added `bool registered' fields to all
3361 silc_idlist_[server|client]_get_* routines to indicate whether
3362 the fetched client needs to be registered or not. Affected
3363 file silcd/idlist.[ch].
3365 * Add your own entry as registered to the ID cache in the
3366 server. Affected file server.c.
3368 * Fixed a bug in silc_server_new_server. The SilcServer was
3369 set as the new server's context instead of SilcServerEntry.
3370 This naturally caused some weird bugs.
3372 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3374 * Do not delete the channel rekey task when adding it
3375 for in silc_server_create_channel_key.
3377 * Changed the silc_server_create_channel_key to return
3378 TRUE or FALSE to indicate the success of the channel key
3381 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3383 * Fixed MSVC++ project files and added missing files to
3384 Makefiles under win32/.
3386 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3388 * Do not add TCP_NODELAY flag if the operating system
3389 does not have it defined. Affected files are
3390 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3392 * Fixed buffer overflow from Irssi SILC Client. Affected
3393 file irssi/src/fe-common/core/themes.c.
3395 * Fixed double free in client library in the file
3396 lib/silcclient/client.c when disconnecting from server.
3398 * Applied double free patch from cras to Irssi SILC client.
3399 Affected files irssi/src/core/[modules/expandos].c
3401 * Fixed the disconnection handling to Irssi SILC Client.
3402 The application must call silc_client_close_connection
3403 in ops->connect client operation in case of failure of
3404 the connection. Affected file is
3405 irssi/src/silc/core/client_ops.c.
3407 * Do not set sock->protocol to NULL in the function
3408 silc_client_close_connection after executing the protocol's
3409 final callback since the sock might not be valid anymore.
3410 Affected file lib/silcclient/client.c.
3412 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3414 * Do not enable SILC_THREADS if the linking with libpthread
3415 did not happen. Affected file configure.in.pre.
3417 * Added notion to protocol specification that server must
3418 verify the sent authentication payload with CMODE when
3419 setting the channel founder key. Implemented it to the
3420 server. Affected file silcd/command.c.
3422 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3424 * Added _EXTRA_DIST SILC distribution variable to the
3425 distributions file. It is used to conditionally add extra
3426 files or directories to the specific distribution. Affected
3427 files ./prepare, Makefile.am.pre and distributions.
3429 Removed the `_' from the start of the distribution names.
3432 * Added README.WIN32 for instructions to compile the Toolkit
3435 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3437 * Fixed a double free in disconnection in the server. Affected
3438 file is silcd/server.c.
3440 * Fixed the lib/silcske/groups.c to work now also with GMP
3441 MP library. The string conversion did not work when using
3442 specific base and the base is indicated in the string as well.
3444 * Created win32/ directory which now includes MSVC++ specific
3445 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3446 It will appear only in the toolkit distribution
3448 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3450 * Changed the key material distribution function in case when
3451 the hash output is too short. The data is now concatenated
3452 a bit differently than it used to. Made the change to the
3453 SKE protocol specification.
3455 * Added better GMP detection to configure.in.pre. A patch
3458 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3460 * Fixed a minor bug in SKE that might cause some problem on
3461 some platforms. Affected file lib/silcske/silcske.c.
3463 * Added the cookie checking for initiator in the SKE. It checks
3464 that the responder returns the sent cookie unmodified. The
3465 affected file is lib/silcske/silcske.c. Added new SKE
3466 error type INVALID_COOKIE that can be sent during the
3467 negotiation. Fixed some memory leaks as well.
3469 * Added the "invalid cookie" error message to Irssi SILC client's
3472 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3474 * Added `task_max' field to the SilcClientParams to indicate
3475 the maximum tasks the scheduler can handle. If set to zero,
3476 default values are used. Affected file lib/silcclient/silcapi.h.
3478 * Fixed memory leaks in silc_client_close_connection. Affected
3479 file lib/silcclient/client.c.
3481 * Added silc_client_del_client_entry to client library to free
3482 all memory of given client entry. Affected file is
3483 lib/silcclient/idlist.[ch].
3485 * Added new functions silc_client_del_channel and
3486 silc_client_del_server to delete channel and server entries.
3487 Affected file lib/silcclient/[silcapi.h/idlist.c].
3489 * Removed silc_client_del_client_by_id from silcapi.h.
3491 * Fixed the INFO command to return the server's own info
3492 correctly when querying by Server ID. Affected file is
3495 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3497 * Removed the non-blocking settings in WIN32 code in the
3498 silc_sock_[read/write] and added SleepEx instead. Affected
3499 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3500 of input data is now checked with FIONREAD and ioctlsocket.
3502 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Call silc_schedule_task_del_by_context in the
3505 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3506 Affected file lib/silccore/silcprotocol.c.
3508 * Call silc_protocol_cancel for active protocols in the
3509 silc_server_close_connection if the funtion
3510 silc_server_free_sock_user_data has not been called.
3511 Affected file silcd/server.c.
3513 * Generic tasks cannot be deleted using the del_by_fd
3514 task deleting function since generic tasks does not match
3515 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3517 * Added a notion to SILCOPER help file that the SILCOPER works
3518 only on router server, not on normal server.
3520 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3522 * Added for WIN32 support for the new scheduler as well.
3523 Affected file lib/silcutil/win32/silcwin32schedule.c.
3525 * Fixed the SHA1 implementation to work on various platforms.
3527 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3529 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3530 API. It is part of the scheduler now. Everything else is
3531 as previously but some functions has changed their names.
3532 Checkout the lib/silcutil/silcschedule.h for the interface.
3533 Updated all applications to use the new interface. Affected
3534 files are lib/silcutil/silcschedule.[ch].
3536 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3538 * Found a bug in the SKE implementation. The HASH value,
3539 specified by the protocol, was not computed correctly. The
3540 public key of the responder was not added to the computation
3541 even though it is mandatory. Affected file lib/silcske/silcske.c.
3542 This unfortunately causes incompatibilities with older
3543 clients and servers.
3545 * Added WIN32 specific network init and uninit functions:
3546 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3547 the Winsock2. Affected file lib/silcutil/silcnet.h and
3548 lib/silcutil/win32/silcwin32net.c.
3550 * Set the socket always to nonblocking mode on WIN32 after
3551 reading data or writing data. Affected file is
3552 lib/silcutil/win32/silcwin32sockconn.c.
3554 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3556 * Fixed various compilation problems under WIN32. Affected
3557 files lib/silcutil/win32/silcwin32thread.c and
3558 lib/silcutil/win32/silcwin32schedule.c.
3560 * Removed all _internal.h #includes from public header
3561 files. Internal headers must never be included from
3564 Removed also the lib/silcske/payload_internal.h file.
3566 * All include files that may be needed (public and some others
3567 included by the public headers) by application developers are
3568 now copied to the ./includes directory. It does not copy any
3569 internal headers. Affected file Makefile.defines.pre and all
3570 Makefile.am's under lib/ and subdirs.
3572 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3574 * Do not change the ~/.silc directory's permissions automatically.
3575 Affected file irssi/src/silc/core/clientutil.c.
3577 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3579 * Do not cancel the protocol in silc_server_close_connection
3580 it might cause recursion. Now cancelled in the function
3581 silc_server_free_sock_user_data. Affected file silcd/server.c.
3583 * Fixed the silc_server_remove_clients_by_server to regenerate
3584 the channel keys correctly finally. Added also new function
3585 silc_server_remove_clients_channels to actually do it.
3586 Affected file silcd/server.c.
3588 * Fixed the silc_server_new_channel to not crash by giving
3589 wrong router to the new channel. Affected file is
3590 silcd/packet_receive.c.
3592 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3594 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3595 which is given as argument to the silc_client_alloc now.
3596 It can be used to configure the client and set various parameters
3597 that affect the function of the client.
3599 * The USERS command in server did not check whether the channel
3600 is private or secret. Affected file silcd/command.c.
3602 * Added new argument to the USERS command in protocol specification.
3603 The USERS command now can take the channel name as argument
3604 as well. Added support for this in client and server and
3605 updated the protocol specs.
3607 * Completed the GETKEY command in client. It can be now used
3608 to fetch also servers public key not only some clients.
3609 Affected files lib/silcclient/command[_reply].c.
3611 * Added silc_client_get_server to return server entry by the
3612 server name. Affected files lib/silcclient/silcapi.h and
3615 * Redefined the IDENTIFY command in protocol specification to be
3616 more generic. It now can be used to query information about
3617 any entity in the SILC Network, including clients, servers and
3618 channels. The query may be based either the entity's name
3619 or the ID. Added support for this in both client and server.
3621 Affected files silcd/command.c and lib/silcclient/command.c
3622 and command_reply.c.
3624 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3625 the _from_client and _from_server functions. Affected file
3628 * Added silc_client_get_channel_by_id_resolve to the file
3629 lib/silcclient/silcapi.h to resolve channel information by
3630 its ID. Added also silc_client_get_channel_by_id that
3631 does not resolve it from the server.
3633 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3635 * Added SilcServerEntry context into the client library
3636 to represent one server. The INFO command now allocates
3637 these to save the resolved server info. For now on the
3638 client library will also keep information about servers,
3639 connected and resolved with INFO.
3641 The INFO command now allocates the SilcServerEntry context
3642 and saves the server info there. The COMMAND_REPLY in
3643 the INFO now returns the parameters to application in
3644 same order as defined in the protocol specification.
3646 The entries are cached in the client->server_cache.
3648 * The INFO command is now issued after received the Client ID
3649 from the server. Affected file lib/silcclient/client.c.
3651 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3652 to the application as the mode changer might be server.
3653 It is guaranteed that NULL is not returned anymore to the
3654 application. Affected file lib/silcclient/client_notify.c.
3656 The ID Type is now also passed to the application so that
3657 it can check whether the returned entry is SilcClientEntry
3660 Added new function silc_client_get_server_by_id to return
3661 the server entry by ID. Affected files are the
3662 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3664 * Do not create the channel in the Irssi SILC Client when issuing
3665 the JOIN command but when received the sucessful JOIN command
3666 reply. Otherwise the channel might get created even though we
3667 could not join it. The Affected file is
3668 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3670 * Fixed a channel joining bug in router. The router must also
3671 check the channel modes, invite and ban lists etc. when serving
3672 the JOIN command sent by normal server. Affected file is
3673 silcd/command.c. The router now resolves the client's
3674 information from the server who sent the JOIN command if it
3675 does not know it, and processes the JOIN command only after
3678 * Changed the SilcCommandCb to take new argument; void *context2.
3679 Affected file lib/silccore/silccommand.h
3681 The second argument in the command callbacks in the server now
3682 includes the SilcServerCommandReplyContext if the command was
3683 called as pending command callback from the command reply.
3684 Otherwise it is NULL. When called as pending the status of the
3685 command reply will be checked and if it was erronous the
3686 error will be sent to the original sender of the command.
3687 This way the client always receives the error messages even
3688 though the server was actually the one who received the error
3689 when it resent the command to router, for example. Affected
3690 files silcd/command[_reply].[ch].
3692 * Fixed sending WHOWAS command's error message to client if
3693 the requested client could not be found. It was missing.
3696 * Changed the CMODE and CUMODE commands reply arguments in the
3697 protocol specification. The Channel ID is now sent in both
3698 of the commands to identify the channel. Implemented this
3699 new feature to the client and server. Affected files
3700 lib/silcclient/command_reply.c and silcd/command.c.
3702 * Made better checks for invite and ban lists in the JOIN
3703 command in server. Affected file silcd/command.c.
3705 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3707 * The server now performs the incoming host IP/DNS lookup
3708 using the silc_socket_host_lookup and thus does not block
3709 the server anymore. Affected file silcd/server.c.
3711 * Completed the multi-thread support for SILC Scheduler in
3712 the lib/silcutil/silcschedule.c.
3714 * Fixed the configure.in.pre to detect the pthread correctly
3717 * Fixed a deadlock in silc_task_queue_wakeup in the file
3718 lib/silcutil/silctask.c.
3720 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3722 * Added new function silc_schedule_wakeup that is used in
3723 multi-threaded environment to wakeup the main thread's
3724 schduler. It needs to be used when a thread adds a new task
3725 or removes a task from task queues. After waking up, the
3726 scheduler will detect the task queue changes. If threads
3727 support is not compiled in this function has no effect.
3728 Implemented the wakeup mechanism to both Unix and WIN32
3729 systems. Affected files are lib/silcutil/silcschedule.[ch],
3730 lib/silcutil/unix/silcunixschedule.c and the
3731 lib/silcutil/win32/silcwin32schedule.c.
3733 * Added new function silc_task_queue_wakeup to wakeup the
3734 scheduler by the specified task queue. Affected file
3735 lib/silcutil/silctask.[ch].
3737 * The silc_socket_host_lookup_start now wakes up the scheduler
3738 after adding the timeout task. Affected file is
3739 lib/silcutil/silcsockconn.c.
3741 * The silc_socket_host_lookup is synchronous now if the threads
3742 support is not compiled in. However, the callback is still
3743 called asyncronously through the scheduler, anyway. Affected
3744 file lib/silcutil/silcsockconn.c.
3746 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3748 * Added new function silc_socket_host_lookup to perform
3749 asynchronous IP and FQDN lookups for the socket connection.
3750 Affected files lib/silcutil/silcsockconn.[ch].
3752 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3754 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3755 that may or may not compile the mutex support in.
3757 Changed the silc_mutex_alloc interface. It allocates the
3758 mutex now to the sent pointer and returns TRUE or FALSE.
3760 Affected file lib/silcutil/silcmutex.h.
3762 * Wrote the SILC Task Queue interface to support multi-threads.
3763 Affected file lib/silcutil/silctask.[ch].
3765 * Wrote the SILC Scheduler to support multi-threads. Affected
3766 file lib/silcutil/silcschedule.c.
3768 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3770 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3771 in lib/silcutil/win32/.
3773 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3775 * Defined SILC Mutex API and SILC Thread API and implemented
3776 them for Unix. Affected files are
3777 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3778 lib/silcutil/unix/silcunixmutex.c and
3779 lib/silcutil/unix/silcunixthread.c.
3781 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3783 * Fixed the silc_server_remove_clients_by_server's channel
3784 key re-generation. The hash table handling was incorrect
3785 and would not work with many channels. Affected file is
3788 * Fixed some memory leaks around the server code.
3790 * Rewrote the silc_server_get_users_on_channel to support IPv6
3791 based Client ID's. Affected file silcd/server.c.
3793 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3794 specification. However, a separate document must be written
3795 to define the detailed signing procedure and the payload
3796 associated with the flag. Defined the flag to the
3797 lib/silccore/silcchannel.h as well.
3799 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3801 * Changed the dynamic tables to static size tables in the
3802 lib/silccrypt/silchmac.c.
3804 * Removed GCC dependencies from the code. A patch by cras.
3806 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3808 * Do not show the error "Error receiving packet bla bla"
3809 in server if it really was not an error (-2 means that reading
3810 is pending). Affected file silcd/server.c.
3812 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3814 * Fixed a possible crash in silc_server_remove_clients_by_server
3815 in silcd/server.c. Fixed there also some memory leaks.
3817 * Fixed the silc_idlist_replace_client_id. It could replace
3818 wrong key in the hash table. Affected file silcd/idlist.c.
3820 * Do not check whether there are global users on the channel
3821 if the channel->global_users is FALSE. Affected functions
3822 silc_server_remove_from_one_channel and
3823 silc_server_remove_from_channels in silcd/server.c. Also,
3824 do not check if the removed client is local as we can be
3825 sure that global client was not removed from the channel
3826 and checking for global users is not needed.
3828 * The silc_server_remove_clients_by_server now re-generates
3829 the channel keys correctly for those channels that had
3830 clients removed from them. Affected file silcd/server.c.
3832 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3834 * Found the reason of random crashes in the server. We weren't
3835 ignoring the SIGPIPE signal (which can be sent in write())
3836 and it crashed the server. Affected file silcd/silcd.c.
3838 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3840 * Assure that sock->user_data is not NULL in the function
3841 silc_server_packet_send in silcd/packet_send.c.
3843 * Disconnect the remote connection if it could not be added
3844 to any ID lists in the server. The affected file is
3847 * Check in silc_server_packet_send[_real/dest] that the
3848 socket is not disconnecting and ignore the data if it is.
3849 Affected file silcd/packet_send.c.
3851 * Define inline to __inline on native WIN32 compilation.
3852 Affected file includes/silcwin32.h.
3854 * Added some explicit type casts for inline code since MSVC
3855 require them. Affected files lib/silcutil/silcbuffer.h,
3856 lib/trq/silcdlist.h and lib/trq/silclist.h.
3858 * Print warning in log files from now on if the packet
3859 decryption fails. Affected file silcd/server.c.
3861 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3863 * Changed the `say' client operation's interface to accept
3864 new `type' argument to indicate the type of the message sent
3865 by the library. The application may filter the library's
3866 messages according the type. The affected file is the
3867 lib/silcclient/silcapi.h.
3869 * Added two new functions to lib/silcclient/silcapi.h:
3870 silc_client_del_client and silc_client_del_client_by_id.
3871 Affected file lib/silcclient/idlist.c.
3873 * Moved the clientincludes.h from includes/ to silc/ and
3874 serverincludes.h from includes/ to silcd/.
3876 * The modes for the CMODE and CUMODE are now passed as
3877 uint32 for application with COMMAND_REPLY. The affected
3878 file is lib/silcclient/command_reply.c.
3880 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3882 * /WHOIS without arguments shows client's own information.
3883 Affected file lib/silcclient/command.c.
3885 * Changed PING to not accept any arguments. The specs
3886 says that client can ping only the connected server so
3887 requiring an argument is not needed. Affected file is
3888 lib/silcclient/command.c.
3890 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3892 * Fixed a fatal bug in private message sending and reception
3893 encryption and decryption when using private message keys.
3894 The implementation was incorrect and did not follow the
3895 specification. It causd that some of the message were
3896 lost since it did not use the sending and receiving keys
3897 as the protocol suggests. This has been fixed and will cause
3898 incompatibilities with older clients when sending private
3899 message encrypted with private message keys. Affected files
3900 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3901 and various other in Irssi SILC Client.
3903 Added `responder' boolean argument to the functions
3904 silc_client_add_private_message_key[_ske] to indicate when
3905 the key is added as responder or initiator of the key
3908 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3910 * Removed the silc_ske_check_version function and created
3911 a SilcSKECheckVersion callback. Added also a function
3912 silc_ske_set_callbacks that is now used to set all SKE
3913 callbacks. The callback functions are not given to
3914 the SKE functions anymore, but this function is used to
3917 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3919 * Added `silc_version' argument to the silc_client_alloc
3920 to define the version of the application for the library.
3921 The library will use the version string to compare it
3922 against the remote host's (usually a server) version
3923 string. Affected file lib/silcclient/silcapi.h
3925 * Added the KE protocol context to Key Agreement context
3926 in client library so that we can abort the SKE if it
3927 is in process when we get timeout. Affected file is
3928 lib/silcclient/client_keyagr.c.
3930 * Do not resolve the client ID forever if it returns in the
3931 first time that such client does not exist. This was done
3932 for example with private message. Affected file is
3933 lib/silcclient/client_prvmsg.c.
3935 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3937 * Do not add regex.h for WIN32. The affected file
3938 includes/silcincludes.h.
3940 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3941 not work yet 100%. It generates the DLL's automatically
3942 when compiling with --with-win32 under cygwin.
3944 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3946 * lib/contrib/regex.c is not compiled on WIN32.
3948 * Added silc_net_get_socket_opt function to the
3949 lib/silcutil/silcnet.h.
3951 * Added includes/silcwin32.h for WIN32 specific includes
3954 * Do not use ptime structure or any of the posix process
3955 functions on WIN32 in lib/silccrypt/silrng.c.
3957 * Added silc_gettimeofday to provide generic function
3958 for struct timeval on all platforms. Added the function
3959 to lib/silcutil/silcutil.h.
3961 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3963 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3964 library as they clearly belong there. As a plus side we
3965 can make the actual socket connection routines platform
3968 Added also new generic function silc_socket_read and
3969 silc_socket_write (that used to be silc_packet_[read/write].
3970 The implementation of these are platform specific.
3972 * Added WIN32 specific routines of silc_socket_[read/write]
3973 to lib/silcutil/win32/silcwin32sockconn.c.
3975 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3977 * Added preliminary support for native WIN32 compilation under
3978 cygwin (using the -mno-cygwin option for GCC) to the
3979 ./configure.in.pre. The --with-win32 now prepares the
3980 compilation for native WIN32.
3982 * Rewrote the SILC Scheduler interface in the file
3983 lib/silcutil/silcschedule.h. The scheduler is now context
3984 based and does not have anymore any global static scheduler.
3985 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3986 and created lib/silcutil/win32 directory for WIN32 based
3989 * Added Unix specific network routines to the
3990 lib/silcutil/unix/silcunixnet.c and the old
3991 lib/silcutil/silcnet.c includes now only generic routines.
3993 Added WIN32 specific network routines to the
3994 lib/silcutil/win32/silcwin32net.c.
3996 * Added Unix specific utility functions from the
3997 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3999 * Added WIN32 SILC Scheduler to the file
4000 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4003 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4005 * Do not handle JOIN notify in the server if the target client
4006 is not registered (idata->registered == FALSE). The affected
4007 file is silcd/packet_receive.c.
4009 * Update the nickrec->founder in event_cumode in the Irssi SILC
4010 client. Affected file irssi/src/silc/core/silc-channels.c.
4012 * Fixed the CUMODE_CHANGE notify handling in the server when
4013 server and router are announcing their clients on channels.
4014 Now the mode changes are saved and notified correctly. The
4015 affected file is /silcd/packet_receive.c.
4017 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4018 They really did not replace the cache entry in the ID Cache.
4019 Now they do that. Affected file silcd/idlist.c.
4021 * Fixed the KICK notify handling in the Irssi SILC client to
4022 update the channel records so that the kicked client does not
4023 appear to be on the channel. The affected file is
4024 irssi/src/silc/core/silc-channels.c.
4026 * Always update the conn->current_channel when executing command
4027 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4029 * Fixed the KILL notify handling in Irssi SILC client to remove
4030 the killed client on all channels.
4032 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Fixed the silc_parse_command_line to remove extra spaces
4035 from the start and end of the arguments. Affected file is
4036 lib/silcutil/silcutil.c.
4038 * Cancel and free any active protocol in the function
4039 silc_server_close_connection. Affected file silcd/server.c.
4041 * Cancel and free any active protocol in the function
4042 silc_client_close_connction. Affected file is
4043 lib/silcclient/client.c.
4045 * Do not execute the KILL command for clients that are in
4046 history (ie. they are not in the network). Affected file is
4049 * Fixed KILL notify handling, client does not crash anymore.
4050 Affected file irssi/src/silc/core/silc-channels.c.
4052 * Reduced the default packet buffer size from 2048 to 1024 in
4053 lib/silccore/silcpacket.c.
4055 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4056 counter to the SKE context that is incresed when the SKE library
4057 performs async operation outside the library. If the outside
4058 process frees the SKE context and FREED status will be set
4059 and the library will detect after the sync operation that the
4060 libary is freed. The affected files are
4061 lib/silcske/silcske[_status].[ch].
4063 * Resolve the client entry information in the function
4064 silc_client_channel_message to assure that NULL pointer is not
4065 passed as client entry to the application. */
4067 * Fixed the task timeout calculation to assure that there is
4068 never negative timeouts. The affected file is
4069 lib/silcutil/silcschedule.c.
4071 * Fixed the channel user mode notification sending in server.
4072 It was sent point-to-point to the router (or to server by router)
4073 but it needs to be destined to a channel. The routines now
4074 supports sending the channel user mode notifys to the channels
4075 when announcing clients and channels. Affected files are
4076 silcd/server.c and silcd/packet_receive.c.
4078 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4079 It did not actually replace the old channel entry in the cache.
4080 Affected file lib/silcclient/client_notify.c.
4082 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Fixed a possible crash in silc_packet_send_prepare. It now
4085 assures always that there is enough space in the buffer and
4086 at the tail area of the buffer (for MAC).
4088 Fixed the inbound buffer reallocation in silc_packet_read.
4089 It was old code and did not handle the reallocation correctly.
4092 The affected file is lib/silccore/silcpacket.c.
4094 * Fixed buffer overflow in silc_parse_nickname in the file
4095 lib/silcutil/silcutil.c.
4097 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4099 * make install generates new server keys only if there is not
4102 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4105 Added check that if the NOREPLY is set then we will not send
4106 the away message. This avoids infinite loop of away messages
4107 if both clients are away. The affected file is
4108 lib/silcclient/client_prvmsg.c.
4110 * Fixed client crash if /NICK was given without arguments.
4111 Affected file lib/silcclient/command.c.
4113 * Server does not send the invite list in INVITE command back
4114 to the client if the list was not altered. Added this notion
4115 to the protocol spec as well. Affected file silcd/command.c.
4117 Fixed possible crash in INVITE command by checking the
4118 value of silc_server_get_client_route command.
4120 * Fixed the INVITE notify type handling. The arguments are now
4121 taken in correct order and client does not crash. The affected
4122 file is irssi/src/silc/core/silc-channels.c.
4124 Removed the "Inviting xxx to channel" message from the
4125 client library away and let the application handle it.
4126 Affected file lib/silcclient/command.c. Added that message
4127 to Irssi SILC client's message formats.
4129 * Fixed CMODE command crash in client. It now checks the
4130 amount of arguments correctly and does not crash. The affected
4131 file is lib/silcclient/command.c.
4133 * Do not create new channel automatically in silc_channels_join
4134 but check whether the channel by that name already exists.
4135 Affected file irssi/silc/core/silc-channels.c.
4137 * Do not send the SERVER_SIGNOFF to router if the disconnected
4138 entity was the router. Affected file silcd/server.c.
4140 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4141 SILC client as it was missing from there.
4143 Added the handling of the KICK notify to the Irssi SILC client
4144 as it was missing. Added "you have been kicked" message to
4145 Irssi SILC client's message modules formats.
4147 Added the handing of the KILL notify to the Irssi SILC client
4148 as it was missing. Added the kill message module formats
4151 The affected file is irssi/src/silc/core/silc-channels.c.
4153 * The router did not save the channel mode the server announced.
4154 Affected file silcd/packet_receive.c.
4156 * Fixed a possible crash in INFO command in server. If the
4157 server did not provide the server info it crashed. Affected
4158 file silcd/command.c.
4160 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Fixed the GETKEY command in the server to check also the
4163 global list. Otherwise the GETKEY would not work correctly
4164 in normal SILC server. Affected file silcd/command.c.
4166 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Fixed GETKEY crash, it crashed if the command did not succseed.
4170 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4173 is now real and not just an macro interface to GMP.
4175 Removed the entire GMP from the source tree and imported new
4176 NSS MPI library instead. Reason for removing GMP is that it is
4177 extremely large and compiles extremely slow. The NSS MPI
4178 is only a few files and compiles in less than 10 seconds.
4179 The speed is also about the same as GMP. The MPI is imported
4180 to lib/silcmath/mpi.
4182 If the system has GMP installed we will still use the GMP.
4183 If it is not then the NSS MPI will be compiled.
4185 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Merged a long nickname (127 characters long) crash bugfix from
4188 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4190 * Merged a freed memory reference bugfix from Irssi CVS tree.
4191 Affected file irssi/src/core/commands.c.
4193 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * Added the server's public key sving and verification to the
4196 server when performing the SKE. This was missing and the
4197 remote server's (or router's) public key was accepted without
4198 checking whether we have it previously or trust it at all.
4199 Affected file silcd/protocol.c.
4201 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Check in the silc_server_timeout_remote if protocol is active
4204 and make sure that the protocol's final callback is called so
4205 that all memory if freed. Affected file silcd/server.c.
4207 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * silc_server_whois_send_reply crashed the server if the nickname
4210 was 127 characters long. Affected file silcd/command.c.
4212 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Added sanity check to the silc_server_new_client. If the hostname
4215 is provided inside username then check that the provided hostname
4216 really is the same as the resolved one. If the hostname was not
4217 resolved then check it from the public key. Affected file is
4218 silcd/packet_receive.c.
4220 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4221 if the server disconnected us and the connection is not valid
4222 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4224 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4225 the library to the lib/silcutil/silcutil.[ch].
4227 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Close log file after open. Affected file
4230 lib/silcutil/silclog.c.
4232 * Check whether sock == NULL in silc_client_send_packet and return
4233 if it is. Affected file lib/silcclient/silcclient.c.
4235 * Check rec->entry == NULL in the Irssi SILC Client before
4236 sending the channel message. Affecte file is
4237 irssi/src/silc/core/silc-servers.c.
4239 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Merged a splitted window bugfix from Irssi CVS tree. The
4242 affected file is irssi/src/fe-text/textbuffer-view.c.
4244 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4245 It did not print nickname.
4247 * Improved the distributions system a bit.
4249 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4252 irssi/src/fe-text/gui-window.c.
4254 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4255 to in-active server. The affected file is
4256 irssi/src/silc/core/client_ops.c.
4258 * Resolve the client in USERS command reply if the entry does
4259 not have username resolved. The affected file is
4260 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4261 command to WHOIS command to really resolve stuff. The USERS
4262 is not used any more in any critical section so WHOIS can
4263 be used even though it might be slower than IDENTIFY.
4265 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4268 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Changed the protocol API a bit more consistent in the
4271 lib/silccore/silcprotocol.[ch].
4273 * Changed the following headers to ROBODoc format:
4275 lib/silccore/silcpayload.h
4276 lib/silccore/silcprotocol.h
4277 lib/silccore/silcsockconn.h
4279 All core library headers are now formatted.
4281 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Fixed a bug in Irssi SILC client; do not show that you are
4284 server/router operator if you really are not. Affected file is
4285 irssi/src/silc/core/client_ops.c.
4287 * Renamed silc_command_free_payload to silc_command_payload_free.
4288 Affected file lib/silccore/silccommand.h
4290 * Added silcmath.h to include the prototoypes of various routines
4291 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4294 * Changed the following headers to ROBODoc format:
4296 lib/silccore/silcchannel.h
4297 lib/silccore/silccommand.h
4298 lib/silccore/silcid.h
4299 lib/silccore/silcidcache.h
4300 lib/silccore/silcmode.h
4301 lib/silccore/silcnotify.h
4302 lib/silccore/silcpacket.h
4303 lib/silcmath/silcmath.h
4305 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4307 * Added checking to the server code not to start the server if
4308 ciphers and stuff are not configured properly. Affected files
4309 silcd/serverconfig.[h] and silcd/server.c.
4311 * Changed the layout of the header files of the public interfaces
4312 in the SILC libraries. The new layout supports ROBODoc
4313 documentation tool (and some others) so that it is easy to create
4314 a library reference manual. All the other headers and source
4315 code must still follow the CodingStyle document. Also source
4316 code must not include these ROBODoc stuffs, only the headers.
4317 Furthermore, all public interface headers must now be named
4318 by using `silc' prefix, example: silcapi.h, silccipher.h.
4319 Some files were renamed due to this. All the other headers
4320 must not be used as public interfaces. I will update the
4321 CodingStyle document later. Changed following headers, so far:
4323 lib/silcclient/silcapi.h
4324 lib/silccore/silcauth.h
4325 lib/silccore/silcprivate.h
4326 lib/silccrypt/silcdh.h
4328 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Removed silc_client_packet_send_flush from the client library
4333 as it is not needed. Affected file lib/silcclient/client.[ch].
4335 * Added printing of message of unresolved authentication method
4336 to the Irssi SILC client. Added it to the module formats.
4337 Removed the same message from the client library.
4339 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Added new distribution feature, DISTLABEL. Every distribution
4342 can define own preprocessor label that can be used in the
4343 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4344 file distributions, acconfig.h.pre and prepare.
4346 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Added Makefile.defines_int to include the actual definitions
4349 for Makefile.defines.in. Tested the new distribution system,
4350 created distributions and tested installation.
4352 * Added AWAY message printing to the Irssi SILC client. Added
4353 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4355 * Added SCONNECT command to call the SILC's CONNECT command.
4356 Cannot use CONNECT directly since Irssi uses that internally.
4357 Affected file irssi/src/silc/core/silc-servers.c.
4359 Added ACTION local command. It is same as ME command but takes
4360 the channel as mandatory argument.
4362 Rewrote some of the Irssi's help files to suite for SILC
4365 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Added Makefile.defines[.in] that should for now on be included
4368 in all Makefile.am file in the source tree. That file includes
4369 all common compilation definitions for SILC source tree.
4371 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Minor changes to the ./prepare script to change the package
4374 name according the distribution name to the configure.in.
4376 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Created new distribution system. Added file `distributions'
4379 that defines all the distributions that can be created out of
4380 the SILC source tree. The ./prepare script now reads that
4381 file to determine how to prepare the distributions. The
4382 first argument to the ./prepare is the name of the distribution
4383 and second is the version of the distribution. If given
4384 without arguments it creates the default (toolkit) distribution
4385 with the default version (defined in ./prepare).
4387 All Makefile.am files that are subject to the distributions
4388 are now named as Makefile.am.pre. These are ./Makefile.am
4389 and lib/Makefile.am. Others may be changed later.
4391 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Added invite list, ban list, some key management and connection
4394 error message printing to module formats in the Irssi SILC client.
4396 * Added new silc_client_set_away_message to set the away message
4397 that is back to the person who sent private message. The
4398 affected file lib/silcclient/silcapi.h and the
4399 lib/silcclient/client_prvmsg.c.
4401 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Fixed the private message sending in the Irssi SILC client,
4404 added local command KEY to the Irssi SILC client.
4406 Added key management and key agreement message formats to the
4407 irssi/src/fe-common/silc/module-formats.[ch].
4409 Added USERS (alias WHO) printing, server/router operator
4410 indication and LIST command printing to the module formats.
4412 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Fixed channel joining notify handling, cumode notify handling
4415 from Irssi SILC client.
4417 * Added SILC specific module-formats to the Irssi SILC client so
4418 that SILC specific message hilighting, colors etc is possible.
4419 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4421 Added channel mode, channel user mode, actions, notices,
4422 whois and whowas printing to the the module-formats.c.
4424 * Fixed a bug in channel deletion in the server. The channel
4425 is not left to the cache even if the channel founder auth mode
4426 is set when there are no users anymore on the channel. Affected
4427 file silcd/server.c.
4429 * The silc_net_localhost now resolves the entire hostname including
4430 the domain name. Affected file lib/silcutil/silcnet.c.
4432 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Changed the ask_passphrase client operation to be ascynchronous.
4435 It has now a completion callback and a context that the
4436 application must call after it has got the passphrase from
4437 the user. Affected files lib/silcclient/silcapi.h,
4438 lib/silcclient/protocol.c, lib/silcclient/command.c and
4441 Added SilcAskPassphrase callback that the application calls
4442 to deliver the passphrase to the library.
4444 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4445 The public key verification and especially a certificate
4446 verification is asynchronous procedure.
4448 Added new SILC_SKE_STATUS_PENDING status to indicate the
4449 request is pending and a callback will be called to finalize
4452 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4453 indicate that remote end did not send its public key (or
4454 certificate), even though we require it. Added check for this
4455 condition in the SKE. This was a security bug, now fixed.
4457 Defined new SilcSKEVerifyCbCompletion callback that is called
4458 when the verification process is completed.
4460 The affected files lib/silcske/silcske_status.h and
4461 lib/silcske/silcske.[ch].
4463 * Changed the verify_public_key client operation to be async
4464 as well. Defined SilcVerifyPublicKey callback that is used to
4465 indicate the success of the public key verification process.
4467 Changed the server and client to use the new async client
4470 * Changed the Irssi SILC client's internal scheduler to be called
4471 twice as many times as it used to be. As a result the client
4472 should be a bit faster now. Affected file is
4473 irssi/src/silc/core/silc-core.c.
4475 * Added support to Irssi SILC client of asynchronous public key
4476 verification and passphrase inquiry. Affected file is
4477 irssi/src/silc/core/silc-core.c.
4479 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Do not say "You have left channel %s" in client library.
4482 Moved it to the application. Affected files are
4483 lib/silcclient/command.c and silc/client_ops.c.
4485 * Fixed silc_client_get_clients. Command context was not
4486 duplicated and was freed memory in the callback. Affected
4487 file lib/silcclient/idlist.c.
4489 * Do not say "you are now talking..." on JOIN command in the
4490 client library. The appliation must handle it.
4492 * Do not say ".. changed topic to" in command reply in the
4493 client libary. The application must handle it.
4495 * Fixed TOPIC command sending in the client library.
4497 * Fixed a memory leak in silc_client_command_free in the file
4498 lib/silcclient/command.c.
4500 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Imported a modified version of Irssi client to the source tree.
4503 The Irssi will be used to create a new client called
4504 Irssi SILC. Imported to irssi/.
4506 Added silc_core_init_finish function to the Irssi. Affected
4507 file irssi/configure.in.
4509 A lot changes in the Makefile.ams around the irssi tree.
4511 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Do not rehash if the new size is same as the old size of the
4514 hash table, in the silc_hash_table_rehash*. The affected file
4515 lib/silcutil/silchashtable.c.
4517 * Replaced hash_table_del_by_context calls from the server
4518 (when channel->user_list and client->channels) to the
4519 hash_table_del as it is sufficient and faster.
4521 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Added silc_hash_table_list, silc_hash_table_get and the
4524 SilcHashTableList structure to provide an alternative way to
4525 traverse the hash table. The affected files are
4526 lib/silcutil/silchashtable.[ch].
4528 * Changed the server's idlist routines to use the hash table
4529 routines to optimize the code.
4531 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Replaced the client entry's `channel' list and channel entry's
4534 `user_list' list to hash tables for optimized lookup. Changed
4535 the code to use the hash table interface around the code.
4536 Affected file lib/silcd/idlist.[ch].
4538 * Added `auto_rehash' boolean argument to the function
4539 silc_hash_table_alloc to indicate whether the hash table should
4540 auto-rehash when it thinks is appropriate time. It will
4541 increase the hash table size if the there is twice as much
4542 entries in the table than the size of the table, and will
4543 decrease the size if there are twice as less entries than
4544 the size of the table.
4546 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4550 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4552 * silc_idcache_purge_by_context deletes the entry now by context
4553 as it is supposed to do. Affected file lib/silccore/idcache.c.
4555 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4556 client is not anymore valid (WHOWAS givens the info) and not
4557 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4559 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Removed the `data' and `data_len' arguments from the ID Cache
4562 interfaces and added `name' argument. ID Cache does not handle
4563 anymore the binary data only a names associated with given ID.
4565 * When hashing a Client ID with silc_hash_id the entire ID is
4566 not hashed anymore, instead only the hash of the Client ID is
4567 hashed. This way we can access the Client ID from the cache
4568 with Client ID but with the hash of the ID (which is a hash of
4569 the nickname) as well without any difference in performance.
4571 Added also silc_idcache_find_by_id_one_ext to do one on one
4572 searching when we have the actual ID. Added also function
4573 silc_hash_client_id_compare. The affected files are
4574 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4576 * When hashing the name associated with a ID it is always done
4577 in lowercase. This way we can access the cache without worrying
4578 about case-sensitivity, even though, for example nicknames are
4581 * Fixed a bug in server with channel message sending. It put
4582 wrong ID type as destination ID. The affected file
4583 silcd/packet_send.c.
4585 * silc_idcache_del_by_context now deletes from all hash tables
4586 by context. Affected file lib/silccore/idcache.c.
4588 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Changed the client library to use the new ID Cache interface.
4591 Changes around the source tree.
4593 * Added silc_hash_table_rehash_ext to rehash with specific
4594 hash function. Affected file lib/silcutil/silchashtable.[ch].
4596 * Added silc_hash_string_compare to compare two strings in the
4597 hash table. Affected file lib/silcutil/silcutil.[ch].
4599 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Added new function silc_idcache_del_by_context into the
4602 lib/silccore/idcache.[ch].
4604 * Changed the server's ID list routines to use the new ID Cache
4605 interface. Changes around the source tree.
4607 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * Added silc_hash_table_del[_by_context]_ext functions in to the
4610 lib/silcutil/silchashtable.[ch].
4612 Removed silc_hash_table_find_all* routines and added new
4613 silc_hash_table_find_foreach to replace them.
4615 Added silc_hash_table_replace_ext function as extended
4616 replacing function. Separated the simple hash table interface
4617 from the extended hash table interface in the file
4618 lib/silcutil/silchashtable.h.
4620 * Fixed minor bugs and changed it to use some of the new
4621 hash table functions in lib/silccore/idcache.c
4623 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * Added new function silc_hash_table_find_all to return all keys
4626 in the hash table by the specified key. As the hash table is
4627 collision resistant it also makes it possible to have several
4628 duplicate keys in the hash table. This function may be used to
4629 find all of the keys from the hash.
4631 Added user_context arguments to the SilcHashFunction,
4632 SilcHashCompare and SilcHashDestructor to deliver user specified
4635 Added new fuctions silc_hash_table_find[_all]_ext to do
4636 extended lookup with specified hash and compare functions and
4637 specified user contexts.
4639 Added new function silc_hash_table_add_ext to add the key
4640 with specified hash function and user context.
4642 Added new function silc_hash_table_foreach to traverse all
4643 entrys in the hash table. Added SilcHashForeach callback
4646 Added new function silc_hash_table_del_by_context to delete
4647 the entry only if the context associated with the key matches.
4649 Affected files are lib/silcutil/silchashtable.[ch].
4651 * Removed silc_hash_[server/client/channel]_id and added just
4652 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4653 silc_hash_id_compare to compare two ID's using as the hash table
4654 comparison function. Added also silc_hash_data to hash
4655 binary data and silc_hash_data_compare to compare it.
4657 * Removed silc_idlist_find_client_by_hash as it is not needed
4658 anymore. Affected file silcd/idlist.[ch].
4660 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4661 to use internally the SilcHashTable. The new ID Cache is a lot
4662 faster than the old one. Some of the ID Cache interface was also
4663 rewritten and obsolete and stupid functions were removed.
4665 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Added entry_count field to the SilcHashTable to keep the number
4668 of the entries in the table. Implemented the function
4669 silc_hash_table_rehash. Added new function
4670 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4672 Fixed a minor bug in silc_hash_table_free.
4674 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4675 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4676 into the lib/silcutil/silcutil.[ch].
4678 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Implemented a collision resistant hash table into the
4681 lib/silcutil/silchashtable[ch]. See the header and the source
4682 for the SilcHashTable API.
4684 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Merged dotconf version 1.0.2 into lib/dotconf.
4688 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Do not compile anything in lib/silcsim/* if the SIM support
4691 is not enabled. The tree should now compile without problems
4694 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Compiled the SILC under cygwin. Compiled and tested briefly
4697 without problems. More tests needed. The SIMs didn't compile
4700 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4702 * Fixed possible crash in silc_get_username in the
4703 lib/silcutil/silcutil.c.
4705 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * Fixed a va_arg in silc/client_ops.c.
4709 * Oops, RC5 routines were named AES and caused some problems
4710 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4712 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Added new SilcIDIP structure into the lib/silccore/id.h and
4715 replaced the old `ip' fields from all SILC ID's to that type.
4716 This is a step towards IPv6 support.
4718 The silc_id_get_len takes now the ID as an extra argument.
4719 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4720 both IPv4 and IPv6 based ID's.
4722 The affected files are lib/silccore/id.[ch] and other files
4723 around the tree using these routines.
4725 * Removed the ID length arguments in server from various
4726 silc_server_send_notify_* routines -> they are not needed
4729 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Fixed memory leak in silc_encode_pem_file in the file
4732 lib/silcutil/silcutil.c.
4734 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Check minor version as well in the SKE. Affected files are
4737 silcd/protocol.c and lib/silcclient/protocol.c.
4739 * Added --identifier option to the server so that an identifier
4740 can be when creating the public key for the server. Affected
4741 file is silcd/silcd.c.
4743 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4744 lib/silccrypt/silcpkcs.c.
4746 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Register default ciphers and stuff when using -C option with
4749 the server. Affected file sildc/silcd.c.
4751 * Put back the servers public key filename format, it is better
4752 than the new one. For now, the client keys are saved with the
4753 new filename format. The affected file silc/client_ops.c.
4755 * Implemented the Cipher API for the rest of the ciphers that
4756 did not implement it or implemented it the wrong way.
4758 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4760 * Register default ciphers and stuff when using the -S option
4761 in the client. Affected file silc/silc.c. Same also when
4762 creating new key pair with -C option.
4764 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Fixed the silc_verify_public_key client operation function to
4767 save the public keys differently. The fingerprint is now
4768 used as filename and not the hostname. This way also the
4769 client keys are saved uniquely and not with hostnames. The
4770 affected file is silc/client_ops.c.
4772 * Trimmed the silc_hash_fingerprint function to remove extra
4773 whitespaces from the end of the fingerprint. The affected
4774 file is lib/silccrypt/silchash.c.
4778 * Added silc_cipher_register_default function to register all
4779 default ciphers. It can be used when configuration files
4780 does not exist and the application does not want any specific
4781 ciphers in any specific order.
4783 The SilcDList is now used as silc_cipher_list dynamically
4784 allocated cipher list. Removed the static list all together
4785 and now all ciphers must be allocated to the dynamic list.
4786 The silc_cipher_alloc routine was changed to check only the
4789 All silc_cipher_* routines that used to return int returns
4792 The affected files lib/silccrypt/silccrypt.[ch].
4794 * The same thing was done to silc_hash_* as for silc_cipher_*
4795 routines. Affected files lib/silccrypt/silchash.[ch].
4797 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4798 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4799 Added also silc_pkcs_[un]register[_default] functions.
4800 Removed the data_context from the PKCS API.
4802 * Added silc_hmac_register_default function to register default
4803 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4804 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4805 to unregister all hmacs at once.
4807 * Register the default ciphers, hash functions, PKCSs and HMACs
4808 if client's configuration file does not exist. The affected
4811 * The client did not load the hash functions from the SIM
4812 modules at all. Added support for this. Affected file is
4813 silc/clientconfig.c.
4815 * When decoding public key with silc_pkcs_public_key_decode, check
4816 the supported algorithm only if PKCS are registered. Affected
4817 file lib/silccrypt/silcpkcs.c. The same was done with the
4818 silc_pkcs_private_key_decode.
4820 * Fixed the SILC List routines to keep the list always in order.
4821 It used to change the list's order when traversing the list but
4822 not it preserves the order. Affected file lib/trq/silclist.h.
4824 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Added the client library to use the SilcSocketConnection's
4827 reference counter (by silc_socket_dup) to prevent the bug that
4828 the socket object may be freed underneath async operation.
4830 * The name resolv library checking fixes in the configure.in.pre.
4833 * Created new version of the protocol drafts for future
4834 development. The -03 drafts are the ones that will be changed
4835 in the trunk now and the -02 will remain as they are.
4837 * Send list of CUMODE notifys to the router when announcing
4838 the channel users to the router. Affected file silcd/server.c.
4839 If the router receiving channel founder CUMODE for a channel
4840 that already has channel founder it will send CUMODE notify
4841 to the sender to remove the channel founder rights from the
4842 announced client. Affected file silcd/packet_receive.c.
4844 * The CUMODE notify may now use Server ID as well as the entity
4845 who changes the mode. Updated protocool specs.
4847 * Updated INSTALL and README files.
4849 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4851 * New web pages in the http://silc.pspt.fi. The pages was
4856 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4858 * Implemented the [DenyConnectin] config section in the server.
4859 Added silc_server_config_denied_conn to check whether incoming
4860 connection is denied. Affected file silcd/serverconfig.[ch].
4862 * Do not check the ports when checking the incoming configuration
4863 data if the port is 0, meaning any. Affected file is
4864 silcd/serverconfig.c.
4866 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Fixed buffer overflow in silc_string_compare in the file
4869 lib/silcutil/silcutil.c.
4871 * Fixed double free in silc_server_command_leave in the file
4874 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4876 * Fixed the version checking in the server. Affected file is
4879 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Fixed the configuration data fetching when accepting new
4882 connections in the server. Affected file silcd/server.c.
4884 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added `sender_entry' argument to the function
4887 silc_server_packet_relay_to_channel so that we can check
4888 whether some destination actually belongs to the same route
4889 the sender belongs (ie, we must not resend the packet to the
4890 sender). Affected file silcd/packet_send.[ch].
4892 * Added `servername' field to the SilcClientEntry in the server
4893 to hold the name of the server where client is from. Affected
4894 file is silcd/idlist.h.
4896 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * Moved the channel message encrypting in the router betwen
4899 router connections from silc_server_channel_message to the
4900 silc_server_packet_relay_to_channel since we want to check
4901 whether we have anybody channel before encrypting anything.
4902 Affected files silcd/packet_[receive/send].c.
4904 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4906 * Fixed the [AdminConnection] server config section to support
4907 multiple entries. Affected file silcd/serverconfig.c.
4909 * Added support into the server to check the validity of the
4910 incoming connection before executing any KE or authentication
4913 * The connection configuration is now saved to the KE and
4914 connection auth protocol contexts and not fetched anymore in
4915 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4917 * The local hosts listenning address and port is also resolved
4918 now when starting the server. We want to have the socket object
4919 to include the real address and port for the listener. Added
4920 new function silc_net_check_local_by_sock into the files
4921 lib/silcutil/silcnet.[ch].
4923 * Fixed a broadcast bug in server -> do not broadcast if we
4926 * Fixed a routing bug. Do not route broadcast packets ever.
4927 Broadcast packets must be processed always and not routed since
4928 they may be destined to some other host than yourself and thus
4929 would get routed without no good reason. Affected file is
4932 * Added function silc_server_config_is_primary_route to check
4933 whether primary router connection has been configured (a router
4934 configuration that we are initiating). If there is not, we
4935 will assume that there is only two routers in the SILC network
4936 and we will use the incoming router connection as our primary
4937 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4939 * Changed the order of the broadcasting. Broadcast _after_ the
4940 packet has been processed not before. Affected file is
4943 * Fixed a [ClientConnection] parsing bug. The port was never
4944 parsed correctly thus resulting to port 0. Affected file
4945 silcd/serverconfig.c.
4947 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4948 argument and did not set the broadcast packet flag. Affected
4949 file silcd/packet_send.c. Fixed same bug in the function
4950 silc_server_send_notify as well.
4952 * If we receive NEW_ID packet for our own ID in the server, ignore
4955 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Removed the nickname from the Private Message Payload.
4960 Updated the code and the protocol specs.
4962 * Updated protocol specs for submitting to the IETF.
4964 * Tweaked the Random Number Generator a bit. Affected file
4965 lib/silccrypt/silcrng.c. Exported a new function
4966 silc_rng_[global]_add_noise which can be used to add more
4969 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Do not parse packets with different timeout when protocol
4972 is active -> may cause problem with rekey. Affected file
4975 * When server receives signoff notify it must not create
4976 new channel key if the client is on any channels since the
4977 sender of the signoff notify will create it.
4979 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4981 * Added printing of error messages during SKE protocol from the
4982 failure packet sent by server during SKE. Affected file
4985 * Removed the client's failure_callback handling with timeout
4986 and handle it immediately when received.
4988 * The SKE library returned wrong type in SUCCESS and FAILURE
4989 packets. They must be 32 bit MSB not 16 bit MSB.
4991 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Ok, rewrote the logic of the re-key and now it seems to work.
4994 I tested it on high traffic with frequent re-keys without
4995 problems. Added hmac_receive (and renamed hmac to hmac_send)
4996 in SilcClientConnection in lib/silcclient/client.h and
4997 in SilcIDListData in silcd/idlist.h. Also, removed the
4998 SilcPacketParserContext's cipher and hmac fields as they are
4999 not needed anymore and actually caused some problems when
5000 the ciphers and hmac's changed underneath the packet parser.
5002 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * If re-key protocol is active then process the incoming packets
5005 synchronously since we must assure that icoming packets encrypted
5006 with the old key is processed before the new keys is set to
5007 use. This is true other packets than for REKEY packets.
5008 Affected file silcd/server.c. The same was done to client library
5009 as well, affected file lib/silcclient/client.c.
5011 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5013 * Fixed bug in client and server to accept the force send if
5014 the packet is send from silc_[server/client]_packet_process
5015 function. Otherwise the packets are never delivered, oops.
5017 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Disable force sending of packets when REKEY protocol is active.
5020 We must assure that no packet is sent directly when rekey is
5021 performed. All packets must be sent through packet queue.
5022 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5023 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5024 function is silc_[server/client]_packet_send_real to check
5027 * Replaced the SIM paths from example config files to
5028 /usr/local/modules. Also, make install creates now
5029 /usr/local/silc/logs directory to hold all the SILC server
5032 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * Made the configure.in.pre work on Solaris. Patch by salo.

5043 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5045 * When MAC computation fails the silc_packet_decrypt returned 0
5046 even though it was supposed to return -1. Fixed this. The
5047 affected file is lib/silccore/silcpacket.c.
5049 * Do not replace the config files in /etc/silc (in make install)
5050 if they already exist. Affected file ./Makefile.am.
5052 * Do not send re-key packets immediately but through packet queue.
5053 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5055 * Changed silc_net_check_host_by_sock to return FALSE if the
5056 IP/DNS could not be resolved. Though, it returns the IP address
5057 now even if it could not resolve it (but returns also FALSE).
5058 Affected file lib/silcutil/silcnet.[ch].
5060 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Added silc_pkcs_decode_identifier to decode the public key's
5063 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5064 Added also silc_pkcs_free_identifier. Added also new context
5065 SilcPublicKeyIdentifier.
5067 * Added -S option to the silc client. It is used to dump the
5068 contents of the specified public key file.
5070 * Changed the PKCS api to return the public key length when
5071 setting the public key.
5073 * Fixed a fatal bug in the public and private key file loading.
5074 Affected file lib/silccrypt/silcpkcs.c.
5076 * Execute the packet parsing for client with zero (0) timeout
5077 if the protocol is active. Affected file silcd/server.c.
5079 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * Made the key generation options to the silcd program. Added
5082 -C option, equivalent to client's option.
5084 * Added new [ServerKeys] config section to the server. It
5085 configures the server's public and private key.
5087 * Defined generic Public Key Payload into the protocol
5088 specification to send specific type of public keys and
5091 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5092 public key or certificate.
5094 * Implemented the GETKEY command to the server and to the
5095 client library and on user interface.
5097 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5133 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Do not ask whether user wants to use the negotiated private key
5136 for private messages, just use it. Affected file is
5137 silc/local_command.c.
5139 * Added `send_enc_key' and `enc_key_len' fields to the
5140 SilcIDListData structure since they are needed in the re-key

5160 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5161 int64 of at least the xintXX size. If void * is less that 4
5162 bytes uint32 * will be used. Defined bool as boolean.
5164 * Changed _ALL_ unsigned long and unsigned int to uint32,
5165 unsgined short to uint16 in the source tree.
5167 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5168 not handle clients that has entry->data.registered == FALSE.
5169 They are not in the network anymore. Affected file is
5172 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Implemented the sending of the SERVER_SIGNOFF notify in the
5175 server. Affected file is silcd/server.c.
5177 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

5186 implemnted the printing of the SERVER_SIGNOFF info to the
5187 application. Affected file silc/client_ops.c.
5189 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5190 if the deleting was successful. Affected file silcd/idlist.[ch].
5192 * Added support for public key authentication in the connection
5193 authentication protocol in the client library. Affected file
5194 lib/silcclient/protocol.c.
5196 * Changed the server's silc_idlist_get_clients_by_* interface
5197 to support already allocated array so that new entries may be
5198 added to pre-allocated array. Affected file silcd/idlist.[ch].
5199 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5200 and command replies.
5202 * All command reply functions in the server now calls the
5203 pending command callback even if error occured. This way the
5204 error will be delivered to the client as well. Affected files
5205 silcd/command.c and silcd/command_reply.c.
5207 * Fixed INFO command to return local server's info if no server
5208 was provided. Affected file lib/silcclient/command.c.

5234 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Added SILC_UMODE_GONE mode to indicate when the client is not
5237 present in the SILC network. Added also support to the local
5238 command AWAY that will set this mode. Added support of showing
5239 "xxx is gone" in WHOIS command. The USERS command shows the
5240 gone status as well.
5242 * Fixed setting server and router operator privileges in the
5243 server's UMODE command. Affected file silcd/command.c.
5245 * Merged the SKE KE1 and KE2 payloads into one payload. The
5246 new KE payload is equivalent to the old KE2 payload.
5248 Cleaned up the SKE Start Payload parsing. It now uses the
5249 simple buffer unformatting to do the parsing. A lot faster
5252 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5253 to the SKE that is used to indicate whether both of the SKE
5254 parties should perform authentication. By default only the
5255 responder performs authentication. By setting this flag also
5256 the initiator must do authentication. By default it is unset
5257 since in normal SKE case, client to server connection, only
5258 the responder should do authentication. When doing SKE between
5259 two clients both should perform authentication. Updated the
5260 code and the protocol specs.
5262 * A little fix to IDENTIFY command in the server. Search the
5263 client first by hash not nickname. Affected file is
5266 * Fixed the silc_client_close_connection to support closing
5267 the client to client connections wihtout deleting too much
5268 data. Affected file lib/silcclient/client.c.
5270 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5271 are received if protocol used to be active but is not anymore
5272 the application would crash due to NULL pointer dereference.
5273 Affected files silcd/server.c and lib/silcclient/client.c.
5275 * Added `hash' field to the SilcClientConnection to include
5276 the hash function negotiated in the SKE protocol.
5278 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5279 to set the channel founder authentication data. A client can
5280 claim the founder rights later by providing the authentication
5281 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5282 This way the channel founder can regain the channel founder
5283 privileges even it is left the channel. This works only on
5284 local server and the client must be connected to the same
5285 server to be able to regain the founder rights. Updated the
5286 protocol specs accordingly.
5288 Added support to the CMODE command in the client to set the
5289 founder auth data. Read the README to see how to set it.
5291 Added support to the CUMODE command to claim the founder
5292 rights. Read the README to see how to do it.
5294 Added support for the founder authentication to the Channel
5295 Entry in the server. Affected file silcd/idlist.h.
5297 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5298 server's CMODE command. Affected file silcd/command.c.
5300 * Added the following new functions into lib/silccore/silcauth.[ch]:
5301 silc_auth_get_method and silc_auth_get_data.
5303 * The server now saves the remote hosts public key to the
5304 SilcIDListData pointer. Affected file silcd/protocol.c.
5306 * The normal server now does not remove the channel entry from
5307 the cache if the founder authentication data is set. It used
5308 to remove it if the founder was the last one on the channel on
5309 the server and left the channel. The auth data is saved and
5310 if the channel is re-joined later the old entry is used with
5311 the old auth data. Affected files silcd/command_reply.c and
5314 * Removed the `pkcs' field from the SilcIDListData structure
5315 in the server; it is not used. Affected file silcd/idlist.h.
5317 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Fixed packet processing on slow links. Partial packets were
5320 never re-processed because the incoming data buffer was cleared
5321 by the application. Application must not directly clear the
5322 sock->inbuf, the packet processing routines handle it. Fixed
5323 this in client library and in server.
5325 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Fixed the WHOIS and IDENTIFY send reply function to really
5328 check whether to send list or just one entry. Affected file
5331 * Cleaned up the LEAVE command's channel key distribution. The
5332 affected file silcd/command.c.
5334 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5335 can enforce the channel mode as well. In that case the ID
5336 includes the ID of the server. The code now enforces the
5337 mode change if the router have different mode than the server.
5339 * The notify client operation with CMODE_CHANGE notify can now
5340 return NULL client_entry pointer if the CMODE was not changed
5341 by client. Application must check for this.
5343 * Added <Server ID> argument to INFO command to support server
5344 info fetching by Server ID.
5346 * Added silc_server_announce_get_channel_users to get assembled
5347 packets of channel users of the specified channel. Affected
5348 file silcd/server.[ch].
5350 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5351 was freed underneath the ID Cache.
5353 * Re-announce clients when the server received CHANNEL_CHANGE
5354 notify from the router. Affected file silcd/packet_send.c.
5356 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5359 crashed since it did not handle the fact that there is no cipher
5360 called "3" and didn't check the error condition. Now fixed.
5362 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5363 flag. It can be used to send message requests.
5365 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5367 * Implemented the RESTART command in the client.
5369 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5370 notice type messages. Added notice printing to the user
5373 * The channel keys are not re-generated if the channel's mode
5374 is PRIVKEY, ie private key on the channel exists. Affected
5375 files silcd/server.c and silcd/command.c.
5377 * Fixed a little bug in channel message delivery when channel
5378 private keys are set in the server. Affected file is
5379 silcd/packet_send.c.
5381 * Changed the setting on channel->on_channel = TRUE from the
5382 silc_client_save_channel_key to the JOIN command reply. The
5383 key payload is not received if the private channel key is set.
5384 Affected file lib/silcclient/command_reply.c and the
5385 lib/silcclient/client_channel.c.
5387 * When the CMODE_CHANGE notify is sent and the channel private
5388 key mode is removed the channel key must be re-generated in
5389 other cells as well. Added this support for the router in the
5390 silcd/packet_receive.c.
5392 * Added new local command NOTICE to send notice message on
5393 channel. Affected file silc/local_command.[ch].
5395 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Added new local command ME to the client. It is used to send
5398 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5399 some action. Affected file silc/local_command.[ch].
5401 * Changed channel_message and private_message client operations
5402 to deliver the message flags to the application. Added also
5403 the `flags' arguments to the silc_client_send_channel_message
5404 and silc_client_send_private_message functions. Affected file
5407 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Redefined the Private Message Payload to support private message
5410 keys and to support the new private message flags. Updated
5411 the protocol specs. Flags makes it possible to have for example
5412 CTCP style messages.
5414 * Added new type SilcPrivateMessagePayload and defined an API
5415 for it in the lib/silcclient/silcprivate.[ch].
5417 * Tested private message private keys successfully. Tested the
5418 private message key set, unset and list commands with the new
5421 * Redefined the Channel Message Payload to include the channel
5422 message flags (equal with private message flags) to support
5423 for example CTCP style messages.
5425 * Defined some of the message (for channel and private message)
5426 flags. Updated the protocol specs and added the flags to the
5427 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5429 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Added SilcKeyAgreementStatus type to the key agreement routines
5432 to indicate the current status and error if one occured.
5433 The status types are defined in the lib/silcclient/silcapi.h.
5435 * Added new local command KEY that is used to set and unset private
5436 keys for channels, set and unset private keys for private messages
5437 with remote clients and to send key agreement requests and
5438 negotiate the key agreement protocol with remote client. The
5439 key agreement is supported only to negotiate private message keys,
5440 it currently cannot be used to negotiate private keys for channels,
5441 as it is not convenient for that purpose.
5443 * Fixed a minor pending callback setting bug in the function
5444 silc_client_get_client_by_id_resolve, now the function works.
5445 Affected file lib/silcclient/idlist.c.
5447 * Added function silc_net_get_local_port to get local bound
5448 port by socket. Added to lib/silcutil/silcnet.[ch].
5450 * Added `sockets' and `sockets_count' fields to the SilcClient
5451 object. They hold the sockets of the listenning sockets in
5452 the client. Listenning sockets may be for example the key
5453 agreement server. Affected file lib/silcclient/client.[ch].
5454 Added functions the silc_client_add_socket and the
5455 silc_client_del_socket. They are exported to the application
5458 * Added ~./silc/clientkeys to support other client's public keys.
5460 * Renamed verify_server_key client operation to verify_public_key
5461 and added one argument to indicate the type of the connection
5462 (server, client etc.).
5464 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Added silc_server_connection_auth_request to handle the
5467 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5468 silcd/packet_receive.[ch].
5470 * Added silc_server_send_connection_auth_request into the
5471 silcd/packet_send.c to send the connection auth request packet.
5473 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5476 * Fixed the public key authentication in responder side in the
5477 server. The `auth_data' pointer includes the SilcPublicKey
5478 not the path to the public key. Affected file silcd/protocol.c.
5480 * Implemented the public key authentication in the initiator side
5481 in the server. Affected file silcd/protocol.c.
5483 * Removed the [RedirectClient] config section from the server
5484 configuration. Is not needed and I don't want to implement it.
5486 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Cleaned up the CMODE command in the server. It now works
5489 correctly and supports all the modes defined in the protocol.
5490 Affected file is silcd/command.c.
5492 * Added `hmac_name' field to the SilcChannelEntry in the server
5493 to hold the default HMAC of the channel. It can be set when
5494 creating the channel (with JOIN command). Affected files
5497 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5498 type to indicate the change of the current cipher and hmac
5499 on the channel. Client can safely ignore the <cipher> argument
5500 (if it chooses to do so) since the CHANNEL_KEY packet will
5501 force the channel key change anyway. The <hmac> argument is
5502 important since the client is responsible of setting the new
5503 HMAC and the hmac key into use.
5505 * Fixed the CMODE command in the client library as well.
5507 * Tested CMODE command in router environment successfully.
5509 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Show the version of the remote client (or server) when connecting
5512 to the server. It is logged to the log file. Affected file
5513 is silcd/protocol.c.
5515 * Fixed the KILLED notify handling in the client library. The
5516 client must be removed from all channels when receiving the
5519 Also, do not remove the client entry when giving the KILL
5520 command but when the KILLED notify is received.
5522 * Removed silc_idlist_find_client_by_nickname from the server.
5523 Not needed anymore. Affected files silcd/idlist.[ch].
5525 * Implemented the CHANNEL_CHANGE notify type handling to the
5526 server. Affected file silcd/server.c.
5530 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Added silc_server_send_notify_invite to send the INVITE
5533 notify between routers.
5535 * Implemented the INVITE command correctly to the server.
5537 * Implemented the INVITE notify type handling in the server.
5539 * Implemented the INVITE command to the client library and on the
5542 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Added function silc_server_get_client_resolve to find the
5545 client entry by ID from all ID lists and then resolve it
5546 (using WHOIS) if it cannot be found. Affected file is
5549 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Implemented the BAN command to the client library.
5553 * The JOIN command in the server now checks the invite list
5556 * Changed the silc_command_reply_payload_encode_va and the
5557 silc_command_payload_encode_va to support that if argument is
5558 NULL it ignores and checks the next argument. Affected file
5559 lib/silccore/silccommand.c.
5561 * Added silc_server_send_notify_ban to send the BAN notify
5562 type between routers.
5564 * Chaned the silc_notify_payload_encode to support that if
5565 argument is NULL it ignores and checks the next argument.
5566 Affected file lib/silccore/silcnotify.c.
5568 * Tested ban lists in router environment successfully.
5570 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Implemented BAN command to the server, in silcd/command.[ch].
5574 * Removed the BAN and INVITE_LIST modes from the CMODE command
5577 * Added function silc_string_match to regex match two strings.
5578 Affected files lib/silcutil/silcutil.[ch].
5580 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Redefined parts of the SilcChannelEntry in the server to support
5583 the new ban and invite lists.
5585 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5587 * Redefined the INVITE command. The same command can be used to
5588 invite individuals to the channel but also to manage the invite
5589 list of the channel (to add to and remove from the invite list).
5590 Updated the protocol specs.
5592 * Added new command SILC_COMMAND_BAN that can be used to manage
5593 the ban list of the channel. Updated the protocol specs.
5595 * Removed the channel modes: the SILC_CMODE_BAN and the
5596 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5597 in the CMODE command. The equivalent features are now available
5598 using INVITE and BAN commands. Updated the protocol specs.
5600 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5601 in the network about change in the current ban list. The notify
5602 type is not used by the client.
5604 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5605 support the invite lists.
5607 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Added new function silc_string_regexify that converts string
5610 including wildcard characters into regex string that can
5611 be used by the GNU regex library. Added into the file
5612 lib/silcutil/silcutil.[ch].
5614 Added silc_string_regex_combine to combine to regex strings
5615 into one so that they can be used as one regex string by
5616 the GNU regex library. Added into the file
5617 lib/silcutil/silcutil.[ch].
5619 Added silc_string_regex_match to match two strings. It returns
5620 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5622 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Imported GNU regex to the soruce tree into lib/contrib.
5625 Fixed some compiler warning from the regex.c.
5627 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Fixed MOTD command in the server to work in router environment.
5631 * Fixed the MOTD command in the client library to support
5632 the server argument in the command.
5634 * Added `nickname_len' argument to the silc_idlist_add_client
5635 in the server, as the `nickname' argument may be binary data
5638 * Added silc_idlist_get_channels to return all channels from
5641 * Implemented LIST command to the server. Affected file is
5644 * Implemented the LIST command to the client library and on the
5647 * Added [<user count>] argument to the LIST command reply.
5648 With private channels the user count is not shown.
5650 * Updated TODO and README.
5652 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * The client entry's data.registered must be TRUE even with
5655 global client entry on global client list. The data.registered
5656 is used to check whether the client is anymore in the network,
5657 for example with WHOWAS command so it must be valid.
5659 * Fixed the WHOWAS command in the server. It now actually works
5660 in router environment. Added function into silcd/command_reply.c
5661 silc_server_command_reply_whowas_save.
5663 * Added silc_idlist_purge function to the silcd/idlist.c
5664 to periodically purge the ID Cache.
5666 * Fixed INFO command in the server. It works now in router
5667 environment. Added <server name> argument to the INFO command
5668 reply. Updated the protocol specs.
5670 * Fixed minor bug in silc_idcache_purge to not purge if the
5671 expire value is zero.
5673 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5674 they were buggy because of the WHOWAS information.
5676 * Fixed local command MSG to handle the async resolving of
5677 the remote client properly. It used to fail the first MSG.
5678 Affected file silc/local_command.c.
5680 * Added `data_len' field to SilcIDCache context.
5682 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Update TODO. Todo in commands in the server.
5686 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5688 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5689 used by routers as broadcast packet to inform other routers
5690 about the changed user mode.
5692 Implemented the notify handling in the server. Affected file is
5693 silcd/packet_receive.c. Added the function
5694 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5696 * Added new generic Channel Payload and deprecated the New Channel
5697 Payload. The New Channel Payload is now the generic Channel
5700 * Added new argument `mode' to the silc_server_send_new_channel
5701 as it is required in the Channel Payload now.
5703 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5704 and created a new and real SilChannelPayload to represent the
5705 new generic Channel Payload. Implemented the encode/decode
5706 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5708 * Added silc_server_get_client_channel_list to return the list
5709 of channels the client has joined for WHOIS command reply.
5710 Affected file silcd/server.[ch].
5712 * Implemented the channel list sending in the WHOIS command reply
5713 in server and in the client.
5715 Implemented the channel list displaying on the user interface
5716 as well. Affected file silc/client_ops.c.
5718 * Added silc_channel_payload_parse_list to parse list of Channel
5719 Payloads. It returns SilcDList list of SilcChannelPayloads.
5720 Client for example can use this function to parse the list of
5721 channels it receives in the WHOIS command reply. The caller
5722 must free the list by calling silc_channel_payload_list_free.
5723 Affected files lib/silccore/silcchannel.[ch].
5725 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Added one new argument <user mode> to the WHOIS command reply
5728 to return the mode of the user in SILC. Updated the protocol
5731 Implemented it to the server and client.
5733 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * Fixed the mode printing on the user interface on joining.
5736 Affected file silc/client_ops.c.
5738 * Implemented the UMODE command and user modes in general to the
5739 client library and to the user interface.
5741 * Implemented the UMODE command to the server.
5743 * The server now sends UNKNOWN_COMMAND error status if client sends
5744 unknown command. Affected file silcd/command.c.
5746 * All server commands now handle the command identifier the right
5747 way when sending the command reply to the client. The client can
5748 use to identify the command replies with the identifier.
5750 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5752 * Added silc_server_get_client_route to resolve the route to
5753 the client indicated by the client ID. Affected file is
5756 * Added silc_server_relay_packet as general function to relay
5757 packet to arbitrary destination. This deprecates functions
5758 like _send_private_message_key, _relay_notify etc. Affected
5759 file is silcd/packet_send.[ch].
5761 Removed silc_server_send_key_agreement,
5762 silc_server_send_private_message_key and
5763 silc_server_packet_relay_notify functions from the file
5764 silcd/packet_send.[ch].
5768 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5769 server. Affected file silcd/packet_receive.[ch].
5771 * Implemented the KILL command to the client. Implemented the
5772 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5773 Affected files lib/silcclient/command[_reply].c and
5774 lib/silcclient/client_notify.c. Implemented the KILL notify
5775 printing in the user inteface.
5777 * Fixed a lot silc_parse_nick memory leaks from the client
5778 library in the file lib/silcclient/command.c.
5780 * Changed the silc_server_send_notify_on_channels's `sender'
5781 argument from SilcSocketConnection to SilcClientEntry to
5782 check the sender as entry and not as connection object and not
5783 to send to the client provided as argument. The affected file
5784 is silcd/packet_send.[ch].
5786 * The notify packets that are destined directly to the client used
5787 to not to be processed by the server. Now changed that and the
5788 server processes all notify packets. After relaying the packet
5789 to the client the notify packet is processed in the server.
5791 * The silc_server_free_client_data now checks whether there is
5792 pending outgoing traffic for the client and purges the data to
5793 the network before removing the client entry.
5795 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5798 an client is killed from the SILC Network. Updated the protocol
5801 Added new function silc_server_send_notify_killed to the
5802 silcd/packet_send.[ch].
5804 * Added function silc_server_packet_relay_notify to relay notify
5805 packets that are destined directly to a client. In this case
5806 the server does not process the notify packets but merely relays
5807 it to the client. Affected file silcd/packet_send.[ch].
5809 Added also silc_server_packet_process_relay_notify to check
5810 whereto relay the notify. Affected file is
5811 silcd/packet_receive.[ch].
5813 * Implemented the KILL command to the server.
5817 * Added the backup schema desgined last fall to the protocol
5818 specs for everyone to see. The specification is in the
5819 *-spec-xx.txt draft and the packet type definitions for the
5820 backup routers is in *-pp-xx.txt draft. Thusly, added also
5821 new packet type SILC_PACKET_CELL_ROUTERS.
5823 * A big security problem in the implementation discovered. The
5824 signoff of an client did not cause new channel key generation
5825 which it of course should've done. The channel keys must be
5826 always re-generated when client leaves (or signoffs) the channel.
5827 The silc_server_remove_from_channels funtion now handles
5828 the channel key re-generation.
5830 * Added `sender' argument to the silc_server_send_notify_on_channels
5831 to not to send the client provided as argument. Affected file
5832 silcd/packet_send.[ch].
5834 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Implemented OPER and SILCOPER commands into the server and
5839 * Added silc_auth_verify and silc_auth_verify_data to verify
5840 the authentication directly from the authentication payload.
5841 It supports verifying both passphrase and public key based
5842 authentication. Affected file lib/silccore/silcauth.[ch].
5844 * Added `hash' field to the SilcIDListData structure. It is the
5845 hash negotiated in the SKE protocol. Affected file is
5848 * Slight redesigning of the SilcAuthPayload handling routines.
5849 Do not send SilcPKCS but SilcPublicKey as argument.
5851 * Implemented the public key authentication support to the
5852 serverconfig. The public key is loaded from the provided path
5853 and saved as authentication data to void * pointer. Thus,
5854 changed the unsigned char *auth_data to void *auth_data;
5856 * Fixed SHUTDOWN command to send the reply before the server
5857 is shutdown. :) Affected file silcd/command.c.
5859 * Fixed fatal bug in CONNECT command. The hostname was invalid
5860 memory and server crashed. Affected file silcd/command.c.
5862 * Fixed fatal bug in CLOSE command. The server_entry became
5863 invalid but was referenced later in the command. Affected file
5866 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Fixed fatal bug in failure packet handling. Server ignored
5869 the failure and thus crashed when it came.
5873 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5876 that the command may be executed only once in (about) 2 seconds.
5877 The old SILC_CF_LAG flag is same but allows command bursts up
5878 to five before limiting.
5880 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5881 server code. Various commands now includes the CF_LAG_STRICT
5882 flag to disallow any kind of miss-use of the command.
5884 * Fixed the silc_buffer_unformat to not to allocate any data
5885 if the length of the data is zero. It used to allocate the
5886 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5888 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Changed the format of AdminConnection configuration section
5891 in the server. Added username of the admin to the format.
5892 Affected files silcd/serverconfig.[ch].
5894 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5895 to return admin configuration data by host, username and/or
5898 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Implemented WHOWAS command to the server. Added the functions:
5902 silc_server_command_whowas_parse,
5903 silc_server_command_whowas_send_reply,
5904 silc_server_command_whowas_from_client and
5905 silc_server_command_whowas_from_server
5907 * Added <Client ID> argument to the WHOWAS command reply. Updated
5908 the protocol specs accordingly.
5910 * Implemented WHOWAS command and command_reply to the client
5913 Implemented the WHOWAS printing on the user interface.
5915 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * Added new argument to the WHOWAS command reply, the real name.
5918 It is an optional argument. Updated the protocol specs.
5920 * Added SilcIDCacheDestructor callback that is registered when
5921 the SilcIDCache is allocated. The callback is called when
5922 an cache entry in the ID Cache expires, or is purged from the
5923 cache. Added into lib/silccore/idcache.[ch].
5925 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5926 to destruct the client entries when the cache entry expires.
5927 Other ID Cache's in server and in the client library ignores
5930 * If the ID Cache entry's `expire' field is zero then the entry
5931 never expires. Added boolean `expire' argument to the
5932 silc_idcache_add function in the lib/silccore/idcache.[ch].
5933 If it is TRUE the default expiry value is used.
5935 * Added silc_server_free_client_data_timeout that is registered
5936 when client disconnects. By default for 5 minutes we preserve
5937 the client entry for history - for WHOWAS command.
5939 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5941 * Added support to the server to enforce that commands are not
5942 executed more than once in 2 seconds. If server receives
5943 commands from client more frequently, timeout is registered
5944 to process the commands. Affected file silcd/command.c.
5945 Added new function silc_server_command_process_timeout.
5947 * Changed NICK_NOTIFY handling in client library to check that
5948 if the client's nickname was changed, so there is no need to
5949 resolve anything from the server.
5951 * Removed error printing from the WHOIS and IDENTIFY commands.
5952 If error occurs then it is ignored silently in the client library.
5953 The application, however, may map the received error to
5954 human readable error string. The application currently maps
5955 the NO_SUCH_NICKNAME error to string.
5957 * Made the command status message public to the application. Moved
5958 them from lib/silcclient/command_reply.c to
5959 lib/silcclient/command_reply.h. The application can map the
5960 received command status to the string with the
5961 silc_client_command_status_message function.
5963 * Added check to the server to check that client's ID is same
5964 as the Source ID in the packet the client sent. They must
5967 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * Added dist-bzip hook to the Makefile.am to make bzip2
5970 compressed distributions.
5972 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5974 * Server now enforces the maximum length for the nickname and
5975 the channel as protocol specification dictates. 128 bytes for
5976 nickname and 256 bytes for channel name.
5978 * Moved the WHOIS printing to the application. The client libary
5979 does not print out the WHOIS information anymore, the application
5980 must do it. Renamed silc_client_command_reply_whois_print to
5981 the silc_client_command_reply_whois_save.
5983 The client's idle time is also sent to the application now, and
5984 the idle is shown on screen.
5986 * Added silc_client_command_reply_identify_save to save the
5987 received IDENTIFY entries.
5989 * Do not check for channel private keys in message sending and
5990 reception if the channel does not have the PRIVKEY mode set.
5991 Affected file lib/silclient/client_channel.c.
5993 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5996 just surfaced after chaning the JOIN procedure.
5998 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6000 * Added silc_client_get_clients_by_list to get client entries
6001 from Client ID list, that is returned for example by JOIN
6002 and USERS command replies. The application should use this
6003 function for example when JOIN command reply is received to
6004 resolve the clients already on the channel (library does not
6005 do that anymore as USERS command reply is not used in the JOIN
6006 procedure anymore). Affected files lib/silcclient/silcapi.h and
6007 lib/silcclient/idlist.c.
6009 * JOIN command reply and USERS command reply returns now SilcBuffer
6010 pointers instead of unsigned char pointers when returning
6011 the client list and mode list.
6013 * Added <Client ID> argument to the JOIN command reply, mainly
6014 for the server to identify for which client the command was
6015 originally sent. Updated protocol specs accordingly.
6017 * Added SilcDlist private_key pointer to the SilcChannelEntry
6018 in the client to support the channel private keys. Affected
6019 file is lib/silcclient/idlist.h.
6021 * Added SilcChannelPrivateKey argument to the function
6022 silc_client_send_channel_message so that application can choose
6023 to use specific private ke if it wants to. If it is not provided,
6024 the normal channel key is used, unless private keys are set.
6025 In this case the first (key that was added first) is used
6026 as the encryption key.
6028 * Implemented the support for channel private key handling.
6029 Implemented the following functions:
6031 silc_client_add_channel_private_key,
6032 silc_client_del_channel_private_keys,
6033 silc_client_del_channel_private_key,
6034 silc_client_list_channel_private_keys and
6035 silc_client_free_channel_private_keys
6037 Affected file lib/silcclient/client_channel.c.
6039 * Added the support for the private keys in the channel message
6040 sending and encryption and in the message reception and
6041 decryption. Affected funtions are
6042 silc_client_send_channel_message and silc_client_channel_message.
6044 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Added SKE's key verify callback to the client library's
6047 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6049 * Removed the statement that server (or router) must send USERS
6050 command reply when joining to the channel so that the client
6051 knows who are on the channel. Instead, the client list and
6052 client's mode list is now sent in the JOIN command reply to the
6053 client who joined channel. This is better solution.
6055 * Added function silc_server_get_users_on_channel and function
6056 silc_server_save_users_on_channel to the silcd/server.[ch].
6058 * Removed function silc_server_command_send_users from the
6061 * Do not show topic on the client library anymore. The topic is
6062 sent in the command reply notify to the application and the
6063 application must show the topic now.
6065 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6067 * Added client searching by nickname hash into the IDENTIFY and
6068 WHOIS commands in the server as they were clearly missing from
6069 them. Affected file is silcd/command.c.
6071 * Fixed a bug in private message receiving in the client library.
6072 The remote ID was freed and it wasn't supposed, now it is
6075 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Minor fix to the channel payload; allocate the data area, as it
6078 needs to be of specific length.
6080 * If the key agreement port is zero then the operating
6081 system will define the bound port. Affected files are
6082 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6084 * Added new function silc_channel_payload_decrypt into the file
6085 lib/silccore/silcchannel.[ch].
6087 * Moved the channel message etc, check from silc_packet_decrypt
6088 to applications. The library calls now a generic
6089 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6090 when the packet is either normal or special. This was done to
6091 allow more wide range of checking that was not allowed when
6092 the code was in library. Now applications can do virtually any
6093 checks to the packet and return to the library the decision how
6094 the packet should be processed. Affected files are
6095 lib/silccore/silcpacket.[ch].
6097 Added silc_server_packet_decrypt_check to the server and
6098 silc_client_packet_decrypt_check to the client library.
6100 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6101 to send with specified source and destination information.
6103 * Channel message delivery between routers was broken after the
6104 channel key distribution was fixed earlier. The channel key
6105 was used be to distributed to other routers as well which is not
6106 allowed by the protocol. Now this is fixed and channel keys
6107 really are cell specific and the channel message delivery between
6108 routers comply with the protocol specification.
6110 * Fixed various commands in server to check also the global list
6111 for the channel entry and not just the local list. The affected
6112 file silcd/command.c.
6114 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * Added assert()s to buffer formatting and unformatting routines
6117 to assert (if --enable-debug) when error occurs. Affected
6118 file: lib/silcutil/silcbuffmt.c.
6120 * Changed to auto-reconnect to check whether the remote host is
6121 router and register the re-connect timeout if it is. It used
6122 to check that whether we are normal server, but router must do
6123 auto-reconnect with another router as well. Affected file
6126 * Removed the [<key len>] option from CMODE command as the cipher
6127 name decides the key length, nowadays. See the defined ciphers
6128 from the protocol specification.
6130 * Added [<hmac>] option to the CMODE command to define the HMAC
6131 for the channel. Added SILC_CMODE_HMAC channel mode.
6133 * Added [<hmac>] option for the JOIN command so that user can
6134 select which HMAC is used to compute the MACs of the channel
6137 * Added Hmac field to the Channel Message Payload. The integrity
6138 of plaintext channel messages are now protected by computing
6139 MAC of the message and attaching the MAC to the payload. The
6140 MAC is encrypted. Now, it is clear that this causes some
6141 overhead to the size of the packet but rationale for this is that
6142 now the receiver can verify whether the channel message decrypted
6143 correctly and also when private keys are set for the channel the
6144 receiver can decrypt the packet with several keys and check from
6145 the MAC which key decrypted the message correctly.
6147 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6148 lib/silccrypt/silccipher.[ch].
6150 * Added silc_hash_len to return the digest length into the
6151 lib/silcrypt/silchash.[ch].
6153 * Rewrote parts of Silc Channel Payload interface in the
6154 lib/silccore/silcchannel.[ch]. The encode function now also
6155 encrypts the packet and parse function decrypts it.
6157 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6159 * Fixed a minor formatting bug in the SKE's key material processing.
6160 It actually might have processed the keys wrong way resulting
6163 * Redefined the mandatory HMAC algorithms and added new algorithms.
6164 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6165 and hmac-md5 truncated to 96 bits. The mandatory is now
6166 hmac-sha1-96. Rest are optional (including the one that used
6167 to be mandatory). Rationale for this is that the truncated HMAC
6168 length is sufficient from security point of view and can actually
6169 make the attack against the HMAC harder. Also, the truncated
6170 HMAC causes less overhead to the packets. See the RFC2104 for
6173 * Added new [hmac] configuration section. The SKE used to use
6174 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6175 is of course wrong. The official names that must be proposed in
6176 the SKE are the ones defined in the protocol specification
6177 (hmac-sha1-96 for example). The user can configure any hmac
6178 using any hash function configured in the [hash] section. At
6179 least, the mandatory must be configured.
6181 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6183 * Added HMAC list to the SKE proposal list. It has now both
6184 hash algorithm list and HMAC list. This makes the protocol
6185 incompatible with previous versions. The SKE now seems to work
6186 the way it is supposed to work, for the first time actually.
6188 * Defined plain Hash algorithms to the protocol specification.
6191 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6193 * Implemented support for key agreement packets into the server.
6194 Added functions silc_server_key_agreement and
6195 silc_server_send_key_agreement. Other than these functions,
6196 server has nothing to do with this packet.
6198 * Added support for private message key packets into the server.
6199 Added functions silc_server_private_message_key and
6200 silc_server_send_private_message_key.
6204 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6205 called in the protocol's final callback instead in the END
6206 protocol state. This makes a little more sense and in the same
6207 time in client we can use the same protocol routines for normal
6208 key exchange and to key agreement packet handling as well.
6210 * Added to both client's and server's KE protocol context the
6211 SilcSKEKeyMaterial pointer to save the key material. We will
6212 bring the key material to the protocol's final callback by doing
6213 this. The final callback must free the key material.
6215 * Added SKE's packet_send callback into client's KE protocol
6216 context so that the caller can choose what packet sending function
6217 is used. This way we can use different packet sending when
6218 doing normal SKE when doing key agreement packet handling (in
6219 the key agreement packet handling we do not want to encrypt
6222 * Implemented the responder side of the key agreement routines
6223 in the client. The client can now bind to specified port and
6224 accept incoming key negotiation. The key material is passed
6225 to the application after the protocol is over.
6227 * Implemented the processing of incoming Key Agreement packet
6228 in the client. Added function silc_client_key_agreement to
6231 * Implemented the intiator side of the key agreement routines
6232 in the client. The client can now initiate key agreement with
6233 another remote client. The key material is passed to the
6234 application after the protocol is over.
6236 * Created client_keyagr.c to include all the key agreement
6239 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6240 SILC_TASK_CALLBACK except that it is not static.
6242 * Created client_notify.c and moved the Notify packet handling
6243 from the client.[ch] into that file.
6245 * Created client_prvmsg.c and moved all private message and
6246 private message key routines from the client.[ch] into that file.
6248 * Create client_channel.c and moved all channel message and
6249 channel private key routines from the client.[ch] into that file.
6251 * Changed silc_client_get_client_by_id_resolve to resolve with
6252 WHOIS command instead of IDENTIFY command, in the file
6253 lib/silclient/idlist.c.
6255 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Implemented the SKE's responder side to the Client library.
6259 * When FAILURE is received to the protocol do not trust it
6260 blindly. Register a timeout to wait whether the remote closes
6261 the connection as it should do it, only after that process the
6262 actual failure. This was changed to both client and server.
6264 * Added client_internal.h to include some of the structures
6265 there instead of client.h in lib/silcclient/.
6267 * Added function silc_task_unregister_by_callback to unregister
6268 timeouts by the callback function.
6270 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * Some "Incomplete WHOIS info" errors has been appearing on the
6273 log files. Took away the entry->userinfo check from WHOIS
6274 reply sending. The entry->userinfo is now " " if client did not
6275 provide one. I thought this was fixed earlier but something
6276 is wrong still. Let's see if the error still appears.
6278 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * Fixed a minor bug in the login when the channel key is
6281 re-generated in the server. It used to generate the key in
6282 wrong order and thus caused problems in the channel traffic.
6284 * Fixed a minor bug in channel key distsribution after
6285 KICK command. The key was not sent to the router even though
6288 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Added silc_ske_process_key_material_data as generic routine
6291 to process any key material as the SILC protocol dictates. The
6292 function is used by the actual SKE library but can be used by
6293 applications as well. This relates to the private message keys
6294 and the channel private keys since they must be processed the
6295 same way the normal SILC session keys. The protocol dictates
6296 this. Affected files: lib/silcske/silcske.[ch].
6298 Added also silc_ske_free_key_material to free the
6299 SilcSKEKeyMaterial structure.
6301 * Defined silc_cipher_set_key function to set the key for
6302 cipher without using the object's method function. The affected
6303 files: lib/silccrypt/silccipher.[ch].
6305 * Implemented silc silc_client_add_private_message_key,
6306 silc_client_add_private_message_key_ske,
6307 silc_client_del_private_message_key,
6308 silc_client_list_private_message_keys and
6309 silc_client_free_private_message_keys functions in the
6312 Added functions silc_client_send_private_message_key to send
6313 the Private Message Key payload and silc_client_private_message_key
6314 to handle incoming Private Message Key payload.
6316 * Added Cipher field to the Private Message Key payload to set
6317 the cipher to be used. If ignored, the default cipher defined
6318 in the SILC protocol (aes-256-cbc) is used.
6320 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6322 * Removed lib/silcclient/ops.h file.
6324 Redefined parts of the SILC Client Library API. Created new
6325 file silcapi.h that deprecates the ops.h file and defines the
6326 published Client Library API. Defined also private message key
6327 API and channel private key API into the file.
6329 This is the file that the application must include from the
6330 SILC Client Library. Other files need not be included by
6331 the application anymore.
6333 * Added new key_agreement client operation callback and also
6334 defined the Key Agreement library API for the application.
6336 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6339 is used by clients to request key negotiation between another
6340 client in the SILC network. If the negotiation is started it
6341 is performed using the SKE protocol. The result of the
6342 negotiation, the secret key material, can be used for example
6343 as private message key.
6345 Implemented the Key Agreement payload into the files
6346 lib/silccore/silauth.[ch].
6348 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Redefined ciphers for the SILC protocol. Added some new ciphers
6351 and defined the key lengths for the algorithms. Changed the
6352 code accordingly. The default key length is now 256 bits.
6354 * Fixed SKE key distribution function silc_ske_process_key_material
6355 when the key length is more than 128 bits. The default key
6356 length in SILC is now 256 bits.
6358 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6359 to indicate unsupported algorithm.
6361 * Renamed rijndael.c to aes.c and all functions as well.
6363 * Fixed a long standing channel key setting bug in client library.
6364 Weird that it has never surfaced before.
6366 * Fixed bug in channel deletion. If the entire channel is removed
6367 then it must also delete the references of the channel entry
6368 from the client's channel list as the client's channel entry and
6369 the channel's client entry share same memory.
6371 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6373 * Implemented CONNECT and SHUTDOWN commands in the client.
6375 * Implemented CLOSE command to the client.
6377 * Added the function silc_idlist_find_server_by_name into the
6378 files silcd/idlist.[ch].
6380 Added the function silc_idlist_find_server_by_conn into the
6381 files silcd/idlist.[ch].
6383 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6385 * DIE command was renamed to SHUTDOWN. Updated the both code
6388 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6389 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6391 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6394 * Added function silc_server_create_connection function to create
6395 connection to remote router. My server implementation actually
6396 does not allow router to connect to normal server (it expects
6397 that normal server always initiates the connection to the router)
6398 so the CONNECT command is only good for connecting to another
6401 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6404 or some other client was kicked from the channel.
6406 Implemented the handling of the notify type to both client
6409 Implemented silc_server_send_notify_kicked to send the KICKED
6410 notify. It is used to send it to the server's primary router.
6412 * Implemented the KICK command into server and client.
6414 * Added `query' argument to the silc_idlist_get_client function
6415 to indicate whether to query the client from server or not if
6418 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6419 to indicate that the client is not channel founder.
6423 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Removed the rng context from SilcPacketContext structure and
6426 changed that the packet routine uses the Global RNG API.
6428 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Added support for quit message that client can "leave" on the
6431 channel when it quits the SILC. It is ditributed inside the
6432 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6434 Added silc_server_free_client_data that will take the
6435 signoff message as argument.
6437 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6439 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Updated parts of the protocol specification to keep it up
6444 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6447 payloads in one packet.
6449 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6450 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6451 use now the new List flag.
6453 * Also deprecated the following packet types: REPLACE_ID,
6454 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6456 * Added list support for Notify packet in server.
6458 * Added silc_server_send_notify_channel_change to send the
6459 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6460 the silc_server_send_replace_id.
6462 * Added silc_server_send_notify_nick_change to send the
6463 NICK_CHANGE notify type. Deprecates the function
6464 silc_server_send_replace_id.
6466 * Added silc_server_send_notify_join to send the JOIN notify type.
6467 Deprecates the function silc_server_send_new_channel_user.
6469 * Added silc_server_send_notify_leave to send LEAVE notify type.
6470 Deprecates the function silc_server_send_remove_channel_user.
6472 * Added silc_server_send_notify_cmode and
6473 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6474 types. Deprecates the silc_server_send_set_mode function.
6476 * Added SERVER_SIGNOFF notify type to indicate that server has
6477 quit. This means that all clients on the channel from that
6478 server will drop. This can be also used when netsplit happens.
6480 Deprecated REMOVE_ID packet type since it is not needed anymore
6483 Added silc_server_send_notify_server_signoff to send the
6484 SERVER_SIGNOFF notify type. Deprecates the function
6485 silc_server_send_remove_id.
6487 Added also silc_server_send_notify_signoff to send the
6488 SIGNOFF notify type.
6490 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6491 SILC protocol from this day on. Changed the protocol
6492 specification as well.
6494 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6495 notify type. It is used between routers to notify about
6496 topic changes on a channel.
6498 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6501 * Partly updated the protocol specification to comply with the
6502 changes now made. It is still though a bit outdated.
6504 * The JOIN notify type now takes one extra argument <Channel ID>.
6505 The packet used to be destined to the channel but now the
6506 JOIN type may be sent as list thus it is impossible to
6507 destine it to any specific channel. By adding this argument
6508 it is again possible.
6510 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6512 * Added CREDITS file. The CHANGES and CREDITS file will appear
6513 in the distribution as well.
6515 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6517 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6518 types in the server's silcd/packet_receive.c.
6520 * Implemented CMODE and CUMODE to work in router environment.
6522 * Fixed minor encoding and decoding buglet from the
6523 lib/silccore/silcmode.c.
6525 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6528 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6530 * Changed all SilcConfigServer* and silc_config_server* to
6531 SilcServerConfig* and silc_server_config*, respectively.
6534 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Associated the ID (client or server ID) to the Authentication
6537 Payload to avoid any possibility of forging. Updated the
6538 protocol specification and the code accordingly.
6540 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6542 * The RSA key length is now save to the RsaKey context in the
6543 key generation process in lib/silccrypt/rsa.c. The key length
6544 is now used to figure out the maximum size of the block allowed
6545 to be encrypted/signed.
6547 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6548 is equivalent to the silc_mp_mp2bin but does not allocate any
6551 * Changed silc_mp_mp2bin API to take length argument. If it is
6552 non-zero then the buffer is allocated that large. If zero, then
6553 the size is approximated using silc_mp_sizeinbase, which however
6556 * Created Global RNG API which is global RNG that application can
6557 initialize. After initializing, any routine anywhere in the
6558 code (including library) can use RNG without allocating a new
6559 RNG object. This was done to allow this sort of use of the
6560 RNG in code that has no chance to allocate RNG object. All
6561 applications currently allocate this and many routines in the
6562 library use this. Affected file lib/silccrypt/silcrng.[ch].
6564 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6565 it to use the Global RNG API.
6567 * Defined Authentication Payload into protocol specification that
6568 is used during SILC session to authenticate entities. It is
6569 used for example by client to authenticate itself to the server
6570 to obtain server operator privileges.
6572 Implemented this payload into the lib/silccore/silcauth.[ch].
6573 Implemented also routines for public key based authentication
6574 as the new protocol specification dictates.
6576 Moved definitions of different authentication methods from
6577 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6579 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6580 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6581 silc_pkcs_verify_with_hash functions into the file
6582 lib/silccrypt/silcpkcs.[ch].
6584 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6586 * The client entry's userinfo pointer must be always valid.
6587 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6588 will fail since it requires the userinfo. Now, the userinfo
6589 is allocated as "" if actual userinfo does not exist. Actually,
6590 it must exist and it is totally Ok to drop client connections
6591 that does not announce the userinfo. However, we will make
6592 this workaround for now.
6594 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6595 to return the remote port by socket.
6597 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6599 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6600 SILC_SERVER_PENDING_EXEC and added an new macro
6601 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6602 data or when error occurs while processing the pending command.
6604 Added new argument `destructor' into silc_server_command_pending
6605 and to the SilcServerCommandPending object. This destructor is
6606 now called after calling the pending callback or if error occurs
6607 immediately. If error occurs the actual pending callback won't
6608 be called at all - only the destructor. The destructor may be
6609 NULL if destructor is not needed.
6611 All this applies for client library code as well. Similar
6612 changes were made there as well for the pending commands.
6614 In the client, the application must now allocate the
6615 SilcClientCommandContext with the silc_client_command_alloc
6618 * Added reference counter to the SilcServerCommandContext. Added
6619 function silc_server_command_alloc and silc_server_command_dup
6622 Same type of functions added to the client library for the same
6625 * Removed the cmd_ident from IDListData away since it is now
6626 global for all connections. It is the command identifier used
6627 in command sending and with pending commands. The affected file
6630 * Added reference counter to the SilcSocketConnection objecet to
6631 indicate the usage count of the object. The object won't be
6632 freed untill the reference counter hits zero. Currently only
6633 server uses this, and client ignores it. The client must be
6634 set to use this too later. The affected files are
6635 lib/silccore/silcsockconn.[ch]. Added also the function
6636 silc_socket_dup to increase the reference counter.
6638 This was mainly added because it is possible that the socket
6639 is removed underneath of pending command or other async
6640 operation. Now it won't be free'd and proper DISCONNECTING
6641 flags, etc. can be set to avoid sending data to connection that
6642 is not valid anymore.
6644 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6645 the connection. After that it sets SILC_SET_DISCONNECTED.
6646 It is, however, possible that the socket data is not still freed.
6647 The silc_server_packet_process now checks that data is not
6648 read or written to connection that is DISCONNECTED. The socket
6649 get's freed when the reference counter hits zero.
6651 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Changed the client operation API: channel_message operation's
6654 `sender' is now the client entry of the sender, not the nickname
6655 and the `channel' is the channel entry, not the channel name.
6657 In the private_message operation the `sender' is now also the
6658 client entry of the sender not the nickname.
6660 Affected file is lib/silcclient/ops.h and all applications
6661 using the client operations.
6663 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6665 * Moved the calling of ops->connect() from connect_to_server_final
6666 into receive_new_id functin since that is the point when the
6667 client is actually allowed to send traffic to network. The
6668 affected file is lib/silcclient/client.c.
6670 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6672 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6673 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6674 (if needs broadcasting) instead of broadcasting the packets one
6675 by one which would make a burst in the network traffic.
6677 * Added `broadcast' argument to the functions in silcd/server.[ch]
6678 silc_server_create_new_channel[_with_id] to indicate whether
6679 to send New Channel packet to primary router.
6681 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6683 * Added new function into the silcd/server.[ch] files:
6684 silc_server_create_new_channel_with_id to create new channel with
6685 already existing Channel ID.
6687 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6688 lib/silccore/silcpacket.h. This packet is used t send list of
6689 Set Mode payloads inside one packet. Server uses this to set
6690 the modes for the channels and clients on those channels, that it
6691 announced to the router when it connected to it. The protocol
6692 specification has been updated accordingly.
6694 * The silc_server_new_channel did not handle the packet coming
6695 from normal server as it normally does not send that. However,
6696 when it announces its channels it does send it. Implemented
6697 the support for that.
6699 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6700 into the file lib/silccore/id.h.
6702 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6704 * Fixed memory leaks in the functions silc_idlist_del_client,
6705 silc_idlist_del_channel and silc_idlist_del_server in the file
6706 silcd/idlist.c. All of those leaked like a sieve.
6708 * Fixed some small memory leaks in the client's function
6709 silc_client_notify_by_server.
6711 * Added functions into silcd/server.c: silc_server_announce_clients,
6712 silc_server_announce_channels and silc_server_announce_server.
6713 These functions are used by normal and router server to announce
6714 to its primary router about clients, channels and servers (when
6715 router) that we own. This is done after we've connected to the
6718 These functions effectively implements the following packet types:
6719 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6720 and SILC_PACKET_NEW_ID_LIST.
6722 * Added new functions into the silcd/packet_receive.[ch]:
6723 silc_server_new_id_list, silc_server_new_channel_list and
6724 silc_server_new_channel_user_list to handle the incoming
6725 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6727 * Added support of changing Channel ID in the function
6728 silc_server_replace_id. If the server that announces a channel
6729 to the router already exists in the router (with same name but
6730 with different Channel ID), router is responsible to send
6731 Replace ID packet to the server and force the server to change
6732 the Channel ID to the one router has.
6734 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6735 client that the Channel ID has been changed by the router. The
6736 normal server sends this to the client. Client must start using
6737 the new Channel ID as the channel's ID.
6739 Implemented handling of this new type into lib/silcclient/client.c
6740 into the function silc_client_notify_by_server.
6742 * Added new function silc_idlist_replace_channel_id into the files
6743 silcd/idlist.[ch] to replace the Channel ID.
6745 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Call silc_server_command_identify_check always when processing
6748 the IDENTIFY command in silcd/command.c
6750 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6753 send keepalive packets. The packet can be sent by clients,
6754 servers and routers.
6756 Added function silc_socket_set_heartbeat into the file
6757 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6758 If not set, the heartbeat is not performed. The actual
6759 heartbeat is implemented in the low level socket connection
6760 library. However, application is responsible of actually
6763 Added silc_server_send_heartbeat to send the actual heartbeat
6764 packet into silcd/packet_send.[ch]. Server now performs
6765 keepalive with all connections.
6767 * Added silc_task_get_first function into lib/silcutil/silctask.c
6768 to return the timeout task with shortest timeout. There was a bug
6769 in task unregistration that caused problems. TODO has been
6770 updated to include that task system must be rewritten.
6772 * The client library will now resolve the client information when
6773 receiving JOIN notify from server for client that we know but
6774 have incomplete information.
6776 * Rewrote parts of silc_server_remove_from_channels and
6777 silc_server_remove_from_one_channel as they did not remove the
6778 channel in some circumstances even though they should've.
6780 * Encryption problem encountered in server:
6782 The LEAVE command used to send the Channel Key packet to the
6783 router immediately after generating it. However, the code
6784 had earlier sent Remove Channel user packet but not immediately,
6785 ie. it was put to queue. The order of packets in the router
6786 was that Channel Key packet was first and Remove Channel User
6787 packet was second, even though they were encrypted in the
6788 reverse order. For this reason, MAC check failed. Now, this
6789 is fixed by not sending the Channel Key packet immediately but
6790 putting it to queue. However, this is more fundamental problem:
6791 packets that are in queue should actually not be encrypted
6792 because packets that are sent immediately gets encrypted
6793 actually with wrong IV (and thus MAC check fails). So, packets
6794 that are in queue should be encrypted when they are sent to
6795 the wire and not when they put to the queue.
6797 However, the problem is that the current system has not been
6798 designed to work that way. Instead, the packet is encrypted
6799 as soon as possible and left to the queue. The queue is then
6800 just purged into wire. There won't be any fixes for this
6801 any time soon. So, the current semantic for packet sending
6804 o If you send packet to remote host and do not force the send
6805 (the packet will be in queue) then all subsequent packets to the
6806 same remote host must also be put to the queue. Only after the
6807 queue has been purged is it safe again to force the packet
6810 o If you send all packets immediately then it safe to send
6811 any of subsequent packets through the queue, however, after
6812 the first packet is put to queue then any subsequent packets
6813 must also be put to the queue.
6815 Follow these rules and everything works fine.
6817 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Added new function silc_server_remove_clients_by_server to
6820 remove all client entries from ID list when the server connection
6821 is lost. In this case it is also important to invalidate all
6822 client entires as they hold the invalid server entry. This
6823 fixes fatal bug when server has lost connection and will reconnect
6826 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Made some sanity checks to silc_server_daemonise like to check
6829 whether the requested user and group actually exists.
6831 * Added sanity check to SKE's silc_ske_responder_finish to check
6832 that the public and private key actually is valid.
6834 * Invalidate the client's nickname when receiving Replace ID
6835 packet and the Client ID is being replaced. This means that the
6836 server will query the nickname if someone needs it (client)
6839 * Sort the ID Cache in client library when the ID Cache data
6840 has changed (needs sorting).
6842 * Do not allow for SILC client to create several connections to
6843 several servers. The client does not support windows right now
6844 and generating multiple connections causes weird behaviour.
6846 Irssi-silc client does support windows and can handle several
6847 connections without problems, see: www.irssi.org and SILC plugin.
6849 * Fixed some places where client was added to the IDList. The
6850 rule of thumb is following (in order to get everything right):
6851 If the client is directly connected local client then the
6852 `connection' argument must be set and `router' argument must be
6853 NULL to silc_idlist_add_client function. If the client is not
6854 directly connected client then the `router' argument must
6855 bet set and the `connection' argument must be NULL to the
6856 silc_idlist_add_client function.
6858 * The funtion silc_server_packet_send_local_channel actually did
6859 not check whether the client was locally connected or not. It
6860 does that now. Fixed a bug related to LEAVE command.
6862 * Fixed Remove Channel User payload parsing bug in server's
6863 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6865 * The server's silc_server_save_channel_key now checks also the
6866 global ID list for the channel as it might not be in the local
6867 list. Fixed a bug related to LEAVE command.
6869 * Is this the end of the [<unknown>] buglet that has been lurking
6870 around for a long time? A little for loop fix in server's
6871 silc_server_command_whois_parse that is used by both IDENTIFY
6872 and WHOIS command. At least, this was a clear bug and a cause
6873 of one type of [<unknown>] buglet.
6875 * WHOIS and IDENTIFY commands call the function
6876 silc_server_command_[whois/identify]_check function even if
6877 we are not router server.
6879 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6881 * Added --with-gmp configuration option. If set the GMP
6882 is always compiled in the SILC source tree. If not set then
6883 it is checked whether the system has the GMP3 installed. If
6884 it has then the GMP won't be compiled (the system's headers
6885 and library is used), if it doesn't have it then the GMP is
6886 compiled in the SILC source tree.
6888 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Changed RSA private exponent generation to what PKCS #1
6891 suggests. We try to find the smallest possible d by doing
6892 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6893 not security fix but optimization.
6895 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Added new config entry [Identity] to fork the server and run
6898 it as specific user and group. A patch from Bostik.
6900 * Imported Dotconf configuration library into lib/dotconf.
6901 This will be used to create the SILC configuration files later.
6902 It will appear in the distsribution after this commit.
6904 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6906 * A big code auditing weekend happening. Auditing code for
6907 obvious mistakes, bugs and errors. Also, removing any code
6910 Removed files for being obsolete:
6912 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6913 inline in the file lib/silcutil/silcbuffer.h)
6915 o lib/silcutil/silcbufutil.c (the header has inline versions)
6917 Changed code to fix possible error conditions:
6919 o The buffer formatting routines now check that the destination
6920 buffer really has enough space to add the data. This applies for
6921 both buffer formatting and unformatting
6922 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6923 unformatting was changed to accomodate following rules:
6924 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6925 sent to the function while XXX_*STRING will not allocate or copy
6926 the data into the buffer. Instead it sets the pointer from the
6927 buffer into the pointer sent as argument (XXX_*STRING used to
6928 require that the pointer must be allocated already). This change
6929 makes this whole thing a bit more consistent and more optimized
6930 (note that the data returned in the unformatting with XXX_*STRING
6931 must not be freed now). The routines return now -1 on error.
6933 o Tried to find all code that use buffer_format and buffer_unformat
6934 and added return value checking to prevent formatting and
6935 especially unformatting errors and possible subsequent fatal
6938 o Changed ske->x and ske->KEY to mallocated pointers in
6939 lib/silcske/silcske.h. Fixed possible data and memory leak.
6941 o Added return value checking to all *_parse* functions. Fixed
6942 many memory leaks as well.
6944 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6945 so that buffer overflows would not happen. All code now also
6946 checks the return value as it can fail.
6948 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Added reconnection support to server if the normal server looses
6951 its connection to the router (for example if router is rebooted).
6952 The server performs normal reconnection strategy implemented
6953 to the server. Affected file silcd/server.c.
6955 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6957 * Added new packet type SILC_PACKET_SET_MODE that is used to
6958 distribute the information about changed modes (for clients,
6959 channels and clients channel modes) to all routers in the
6960 network. Updated the protocol specification accordingly.
6962 Added functions into silcd/packet_send.c and
6963 silcd/packet_receive.c: silc_server_send_set_mode,
6964 silc_server_set_mode.
6966 Added new files silcmode.[ch] into lib/silccore that implements
6967 the encoding and decoding of Set Mode Payload. Added new type
6968 SilcSetModePayload. Moved the definitions of different modes
6969 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6971 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Oops, a little mistake in server's connection authentication
6974 protocol. The protocol is not ended with FAILURE but with
6975 SUCCESS if the authentication is Ok. :) Affected file is
6978 * Implemented NICK_CHANGE notify handling in server in the file
6979 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6980 the local clients on the channel. After the changing nickname
6981 in router environment snhould work and the [<unknown>] nickname
6982 should appear no more.
6984 The silc_server_replace_id function that receives the Replace ID
6985 payload now sends the NICK_CHANGE notify type also in the file
6986 silcd/packet_receive.c
6988 * Changed WHOIS and IDENTIFY command to support the maximum amount
6989 of arguments defined in protocol specs (3328 arguments). This
6990 fixed a bug that caused problems when there were more than three
6993 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6995 * Added extra parameter, command identifier, to the
6996 silc_client_send_command so that explicit command identifier
6999 Changed that ID list routines uses specific command identifier
7000 when sending WHOIS/IDENTIFY requests to the server so that they
7001 can be identified when the reply comes back.
7003 Affected files lib/silcclient/command.[ch],
7004 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7006 * Added `sender' argument to silc_server_packet_send_to_channel
7007 to indicaet the sender who originally sent the packet to us
7008 that we are now re-sending. Ignored if NULL. Affected file
7009 silcd/packet_send.[ch].
7011 * Added some server statistics support in silcd/server_internal.h
7012 SilcServerStatistics structure and around the server code. Also
7013 send some nice statistics information when client is connecting
7016 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Fixed channel ID decoding in server's JOIN command reply in
7019 silcd/command_reply.c
7021 * Fixed braodcasting of replace ID payload to not to send it if
7022 we are standalone server in silcd/packet_receive.c.
7024 * Fixed all channel message sending routines to not to send
7025 packets to clients that has router set, since they are routed
7026 separately in the same function earlier. Affects file
7027 silcd/packet_send.c and all channel packet sending functions.
7029 * In USERS reply, res_argv[i] are not allocated, the table
7030 is allocated. Thus changed that free the table, not its
7033 * In server's whois_check and identify_check if the client is
7034 locally connected do not send any WHOIS commands - they are not
7037 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7039 * Fixed some minor bugs in client when sending WHOIS command. The
7040 arguments was in wrong order.
7042 * Removed statis function add_to_channel from server in
7043 silcd/command.c that was previously used with the joining but
7046 * Tested USERS command in router environment successfully with two
7047 routers, two servers and two clients.
7049 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7051 * Reorganized the USERS command and command reply in client library
7052 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7053 When the command is given by user we register a pending command
7054 callback that will reprocess the command after the reply has been
7055 received from the server. When reprocessing the packet we then
7056 display the information. Thus, the USERS information is displayed
7057 now in the command callback instead of in the command reply
7058 callback. The processing of the command is same as previously
7059 when server has sent the command reply in the JOINing process.
7061 * Added to USERS command in silcd/command_reply.c to join the client,
7062 we didn't use to know about, to the channel after we've created
7063 a client entry for it. Also, for clienet we did know already still
7064 check whether it is on the channel or not and add it if not.
7066 * Removed silc_server_command_join_notify as the function and its
7069 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7071 * Changed the client's pending command handling to the same as the
7072 server's pending command handling. It is also now possible to
7073 execute command reply functions from other command reply
7074 function as the function callbacks for commands and command
7075 replies are one and same. The pending commands are not static
7076 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7077 in client connection context. Thus, pending commands are server
7078 connection specific as it is convenient.
7080 Changed the function silc_client_command_pending and
7081 silc_client_command_pending_del and added new function
7082 silc_client_command_pending_check. Removed the
7083 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7086 * Added cmd_ident, current command identifier, to the client
7087 connection context in lib/silcclient/client.h to keep track on
7088 command identifiers used in command sending. Client's command reply
7089 function handling now supports the mandatory command identifiers.
7091 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7092 funtions in client to fully support pending command callbacks.
7094 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7095 as one of the arguments to the application in the command reply
7098 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7099 before first releasing SILC but came back. Now it is removed again
7100 and should come back nomore. The FORWARDED flag was used only
7101 by the JOINing procedure by forwarding the command packet to router.
7102 Now, the JOINing procedure has been changed to more generic (due
7103 to various router environment issues) and FORWARDED is not needed
7104 anymore for anything. The protocol specification is yet to be
7107 Now, removed silc_server_packet_forward from server and the flag
7108 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7110 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7112 * Renamed NAMES command to USERS command. The NAMES was named that
7113 due to historical reasons. Now it is renamed. Also, rewrote
7114 parts of the USERS command. The nickname list is not sent anymore
7115 by the server. Only Client ID and mode lists are sent in the USERS
7116 command. Changed this also to the protocol specification.
7118 The client now resolves the names and stuff after it receives
7119 the USERS list from the server when joining to the channel.
7121 * WHOIS and IDENTIFY commands has been changed to support multiple
7122 Client ID's per command. One can now search for multiple users
7123 in the network by sending only one WHOIS or IDENTIFY command.
7124 Changed the code and the protocol specifications.
7126 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7127 uses silc_server_command_whois_parse to parse the request. */
7129 * If normal server, do not parse the WHOIS and IDENTIFY requests
7130 before sending it to the router. Saves some time.
7132 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7134 * Fixed JOIN command on client library. Wrong number of arguments
7135 used to crash the client.
7137 * Added silc_server_channel_has_global function to check whether
7138 channel has global users or not.
7140 * Added silc_server_channel_has_local function to check whether channel
7141 has locally connected clients on the channel.
7143 * The silc_server_remove_from_one_channel now checks whether the
7144 channel has global users or not after given client was removed from
7145 the channel. It also checks whether the channel has local clients
7146 on the channel anymore. If it does not have then the channel entry
7147 is removed as it is not needed anymore.
7149 * The silc_server_notify now checks on JOIN notify whether the joining
7150 client is one of locally connected or global. If it is global then
7151 the channel has now global users on the channel and that is marked
7152 to the channel entry. Also, it now saves the global client to
7153 global list who is joining and JOINs it to the channel. This is
7154 for normal server, that is.
7156 Changed silc_server_send_notify_on_channel,
7157 silc_server_packet_relay_to_channel and
7158 silc_server_packet_send_to_channel check if we are normal server
7159 and client has router set (ie. global client) do not send the
7160 message to that client, as it is already routed to our router.
7162 * Implemented LEAVE notify type handling in silc_server_notify
7165 * Tested LEAVE command in router environment successfully. Tested
7166 with two routers, two servers and two clients.
7170 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7172 * Implemented SIGNOFF notify type handling in silc_server_notify
7175 * silc_server_remove_id now removes the client entry from all channels
7176 it has joined and thusly sends SIGNOFF notify type.
7178 * Rewrote the NAMES list generation in server by removing two excess
7179 loops. The lists are created now inside one loop.
7181 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * silc_server_remove_channel_user checks now also global list
7184 for channel and client.
7186 * silc_server_new_channel_user checks now both local and global
7187 list for channel and client. Fixed a bug in client id decoding.
7188 Used to decode wrong buffer.
7190 * silc_server_channel_message checks now both local and global
7191 list for channel entry.
7193 * Tested channel joining (hence JOIN) in router environment
7194 successfully. Tested with two routers, two servers and two
7197 * Tested channel message sending in router environment successfully.
7199 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7201 * Added silc_server_save_channel_key into server.[ch] to save the
7202 received channel key in Channel Key payload processing. It is
7203 also used in JOIN command reply handling.
7205 Equivalent function silc_client_save_channel_key added into
7206 client.[ch] into client library.
7208 * Changed JOIN command reply to send information whether the channel
7209 was created or not (is existing already) and the channel key
7210 payload. Changed protocol specs accordingly.
7212 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7213 the request was sent by ID and not by nickname. Crashed on
7216 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7218 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7219 now correctly save the received data.
7221 * silc_server_free_sock_user_data now notifies routers in the
7222 network about entities leaving the network.
7224 At the same time implemented functions silc_server_remove_id
7225 and silc_server_send_remove_id to receive and send REMOVE_ID
7226 packets. The packet is used to notify routers in the network
7227 about leaving entities. The ID removed will become invalid in
7230 * Added function silc_idlist_del_server into server. Removes and
7231 free's server entry from ID list.
7233 * silc_server_private_message function now checks, if we are router,
7234 that the destination ID really is valid ID, naturally.
7236 * In router when NEW_ID packet is received (for new client) the
7237 hash of the Client ID is saved in the ID Cache but the
7238 client->nickname is set to NULL, instead of putting the hash
7241 IDENTIFY command now also checks that client->nickname must be
7242 valid. If it is not if will request the data from the server who
7243 owns the client. Added new function
7244 silc_server_command_identify_check.
7246 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7247 to set the command to already allocated Command Payload.
7249 * Tested private message sending in router environment with two
7250 routers, two servers and two clients. Fixed minor bugs and now
7253 * Fixed segfault from client's NAMES command. Used to crash if
7256 * Forwarded packets must not be routed even if it is not destined
7257 to the receiver. Changed server code comply with this.
7259 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7261 * Added `require_reverse_mapping' boolean value to ServerParams
7262 structure. If TRUE (not default) the server will require that
7263 the connecting host has fully qualified domain name.
7265 If the reverse mapping is not required and hostname could not be
7266 found the IP address is used as hostname.
7268 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7270 * Implemented version string checking to both client and server.
7271 The check is incomplete currently due to the abnormal version
7272 strings used in development version of SILC.
7274 * Changed all command functions in server to use the new
7277 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7279 * Changed char *data to unsigned char *data in ID Cache system to
7280 support binary data as ID Cache data. Changed code to support
7281 binary data in lib/silccore/idcache.c.
7283 * Renamed silc_server_packet_relay_command_reply to
7284 silc_server_command_reply as it is normal packet receiving
7285 function. Rewrote the function to accept command replys for
7286 servers and not only for clients.
7288 * Mark remote router always as registered server if we are connecting
7289 to it. Otherwise, commands sent by the router to us are ignored.
7291 * All ID List find routines now returns the ID Cache Entry pointer
7292 as well if requested.
7294 * WHOIS command works now in router environment, tested with two
7295 routers, two servers and two clients.
7297 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7298 in router environment (as it is almost equivalent to WHOIS) but
7299 hasn't been tested thoroughly. Added new functions:
7301 silc_server_command_identify_parse
7302 silc_server_command_identify_send_reply
7303 silc_server_command_identify_from_client
7304 silc_server_command_identify_from_server
7306 * Disabled route cache adding because adding two different ID's with
7307 same IP replaces the old cache entry thus giving wrong route.
7308 The entry->router->connection is always the fastest route anyway
7309 so route cache may not be needed. Of course, new routes maybe
7310 established after receiving the ID when the entry->router->connection
7311 might not be anymore the most optimal.
7313 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7315 * Add route cache for received ID for fast routing.
7317 * Added silc_server_packet_route to route received packet on router
7318 that is not destined to us.
7320 * Renamed silc_server_get_route to silc_server_route_get.
7322 * Added id_string and id_string_len fields into SilcServer to
7323 include encoded ServerID for fast comparing without excess
7324 encoding of the ID's.
7326 * Cleaned up WHOIS command on server side. Added following static
7329 silc_server_command_whois_parse
7330 silc_server_command_whois_check
7331 silc_server_command_whois_send_reply
7332 silc_server_command_whois_from_client
7333 silc_server_command_whois_from_server
7335 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7336 arguments in command replies. All command functions should be
7337 updated to use this macro.
7339 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7341 * Minor typo fixes on command reply handling on server.
7343 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7345 * Added silc_server_command_add_to_channel internal routine to add
7346 the client to the channel after router has created the channel and
7347 sent command reply to the server.
7349 * Added generic silc_server_send_command to send any command from
7352 * Use static buffer with ID rendering instead of duplicating data.
7354 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7356 * Fixed a channel user mode bug when joining to a channel server gave
7357 everybody channel founder rights, oops.
7359 * We mark ourselves as the router of the incoming server connection
7360 if we are router ourselves. This way we can check in some packet
7361 sending functions whether it is locally connected server. For
7362 incoming router connections we put NULL.
7364 * For router sending packets locally means now always sending the
7365 packet cell wide; to local clients and local servers. For normal
7366 server sending packet locally means sending it to only local
7369 * Fixed the JOIN command to really work in router environment. If the
7370 channel is created it is always created by the router. Router is
7371 also responsible of making the initial joining to the channel,
7372 sending JOIN notify to the sending server and distributing
7373 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7374 does not exist server doesn't do anything else but forward the
7375 command to the router which performs everything.
7377 * Added silc_server_send_channel_key function to send the Channel Key
7380 * Added silc_server_create_channel_key to create new channel key. The
7381 channel key is now re-generated everytime someone joins or leaves
7382 a channel, as protocol dictates. Note: channel->key_len is the
7385 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7387 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7388 packet_receive.[ch] to separate packet sending and receiving
7389 routines. The server.[ch] now includes everything else including
7390 actual packet processing (writing and reading data) and other
7393 Renamed silc_server_private_message_send_internal to
7394 silc_server_send_private_message. The routine is still though
7395 used only to relay private messages as server does not send
7396 private messages itself.
7398 Renamed silc_server_new_channel to silc_server_create_new_channel
7399 and added new function sicl_server_new_channel that handles the
7400 incoming New Channel packet. Added also new sending function
7401 silc_server_send_new_channel to send New Channel Payload.
7403 * Added new function silc_server_notify to process incoming notify
7404 packet to the server/router. Server may then relay the notify
7405 to clients if needed.
7407 * Added new function silc_server_new_channel_user to process incoming
7408 New Channel User packet. Router will redistribute the packet and
7409 send JOIN notify to its local clients and locally connected servers
7410 if needed. Normal server will send JOIN notify to its local client
7411 on same channel when received this packet. Added also corresponding
7412 sending function silc_server_send_new_channel_user to sent the
7415 * Added boolean route argument to send_notif_to_channel and
7416 packet_send_to_channel functions to attempt to route the packet
7417 if it is TRUE and send only locally if it is FALSE.
7419 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7421 * silc_server_replace_id now broadcasts the received replace ID
7422 packet if it is not broadcast packet already. The router must
7423 broadcast to inform other routers about changed ID.
7425 * Added backpointer to server's router into SilcServer context in
7426 silcd/server_internal.h.
7428 * Fixed silc_server_packet_broadcast to send correct broadcast
7431 * The channel key is now distributed to the local client as soon
7432 as it is received from the router (in router environment) so that
7433 no other packet may be sent for the channel until client has
7436 * silc_server_remove_channel_user now broadcasts the received
7437 Remove Channel User packet if it is not broadcast packet already.
7438 The router must broadcast to inform other routers about removed
7441 * Added users field into SilcPacketContext that is a reference count
7442 of the context. One can increase the reference count by calling
7443 silc_packet_context_dup which is now changed to just increase the
7444 reference count instead of duplicating the data. The reference
7445 count is decresed by calling silc_packet_context_free that will
7446 free the data after the reference count hits zero.
7448 For now on the packet context and everything allocated into it
7449 (including the raw packet from network) must be freed by calling
7450 the new silc_packet_context_free function. Added also new function
7451 silc_packet_context_alloc that must be used now to allocate the
7452 context. This also means that if a routine is asynchronous from
7453 silc_[client/server]_packet_parse_type the packet context must
7454 be duplicated by calling silc_packet_context_dup. Otherwise it
7455 gets free'd after silc_[client/server]_packet_parse_type returns.
7456 Also, one must remember that if packet is duplicated then its
7457 reference count must be decresed by calling the free function as
7458 many times as it was duplicated.
7460 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7461 from both client and server.
7463 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7465 * Made joining to a channel working in router environment.
7467 * Cleaned up JOIN command on server side and create function
7468 silc_server_command_join_channel internal routine to make the
7471 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7473 * Changed silc_command_pending list to SilcDList. Also, added
7474 `ident' field to SilcServerCommandPending structure to identify
7475 the reply and to call correct callback.
7477 Added silc_server_command_pending_check function to replace the
7478 corresnponding macro. The silc_command_pending list is not
7481 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7482 to set identifier to previously allocated Command Payload. It
7483 is used to set identifier for command when resending Command
7486 * Added silc_command_payload_encode_payload to encode Command
7487 Payload buffer from SilcCommandPayload structure.
7489 * Added silc_argument_payload_encode_payload to encode Argument
7490 payload buffer from SilcArgumentPayload structure.
7492 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7494 * Changed WHOIS command to support router connection on server side.
7495 The whois request is always sent to router unless the server is
7496 standalone server. After server has received the reply from the
7497 router will it send the reply to the client.
7499 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7500 broadcast received broadcast packet. The function is used only
7501 by router. The broadcast packet is always sent to the router's
7504 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7505 render given ID to printable string, for log files for example.
7507 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7509 * Made basic router to router connections working. At least they
7510 can now connect to each other but nothing really works the way
7511 they are supposed - yet.
7513 * Added new initiator token to RouterConnection configuration
7514 file in silcd/serverconfig.[ch]. It is used to tell whether we
7515 are the initiator to the remote router or whether we'll expect
7516 the other end to connect.
7518 * Moved registering of listener task to silc_server_init, hence
7519 the server starts listenning as soon as it is run, even if it
7520 does not have connections to other routers. Let's see how well
7523 * Changed default connection retry timeouts for more suitable in
7526 * Removed cipher and such arguments from silc_idlist_add_client
7527 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7528 Added new function silc_idlist_add_data to add the keys and stuff
7531 * Added SilcIDListData structure and added it to SilcClientEntry
7532 and SilcServerEntry as their first field in the structure. This
7533 way we can explicitly cast the ID entries to the SilcIDListData
7534 structure and get common data for the entries. In past, we had
7535 to first check what type of connection it is and then cast it to
7536 correct ID entry type. Now, we can directly cast the opaque
7537 pointer to the SilcIDListData (no matter what ID entry it actually
7538 is) and get the data needed.
7540 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7542 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7543 in some circumstances even if threre were timeout tasks, though not
7544 IO tasks, but tasks anyway. Now fixed.
7546 * Defined SilcServerConnection structure to hold connection specific
7547 stuff about directly connected servers and routers. The definition
7548 is currently in silcd/server_internal.h. I thought about having
7549 a bit more important role fro this struct but for now it is used
7550 only when connecting to other server (or router actually).
7552 * Added connecting retry support in server when connecting to
7553 router(s). The retry feature implement exponential backoff
7554 algorithm. Also, added SilcServerParams structure to hold default
7555 parameters for server. For now, it include these retry settings
7556 and are hard coded. After server is moded to be as Silc Server
7557 Library this structure will be more important.
7559 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7561 * Changed client librarys channel->clients table to SilcList and
7562 changed code accordingly.
7564 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7566 * Changed client's channel table to SilcList and changed code
7567 accordingly. Also changed SilcChannelClientEntry to include back-
7568 pointer to the channel so that client entry can use that structure
7569 as list as well and we have fast cross-reference to the channel.
7570 This change dramatically decreased the complexity of channel
7571 handling with client entry and vice versa (removed one extra
7572 loop when searching for channel entry from many functions).
7574 * Changed server->sim from table to SilcDList and changed code
7577 * NAMES command can now be used from user interface. It will show
7578 the user list on the channel, neatly.
7580 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7581 Code now saves realname of the user if it becomes available.
7583 * Renamed configure.in to configure.in.pre and made ./prepare
7584 script to automatically add correct version string to
7585 configure.in which it creates from configure.in.pre.
7587 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7589 * NAMES command reply now shows users mode with the nickname when
7592 * Moved silc_client_ch[u]mode[_char] functions from
7593 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7594 place sucks, they are utility functions and should be in some
7597 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7599 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7602 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7606 * Added TRQ (efficient deque and list library) into lib/trq. This is
7607 a very good list library that is currently used in the SILC. Defined
7608 SilcList API over the library because I didn't like the API very
7609 much. See lib/trq/silclist.h for the API and examples of how to
7610 use the API. Fixed various places in the code to use the new
7611 SilcList API. The SilcList is meant for lists that has a structure
7612 already defined as a list. It is not suitable to add just some
7613 context to the list (in TRQ, the context is the list actually).
7615 So, I defined SilcDList that can be used for the purpose where
7616 predefined list structure does not exit. This can be used as
7617 such list. Now some context just can be added to the SilcDList.
7618 Currently this list is not used in the SILC just yet, though there
7619 are a lot places where this can replace dynamically allocated
7620 tables and I will fix these places, later, to use SilcDList.
7621 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7622 and use TRQ internally).
7624 Also fixed some annoying warning messages that the original TRQ
7625 code generated. Also minor changes to TRQ's Makefile.in.
7627 * Added support for querying by Client ID to both WHOIS and
7628 IDENTIFY commands into server, as required by the protocol.
7630 * Removed method function pointers from SilcBuffer structure. They
7631 weren't used to anything and just increased the context size for
7632 no good reason. This change also made silc_buffer_alloc and
7633 silc_buffer_free functions inline functions.
7635 * Disabled command flooding detection support until it's fixed so
7636 that it accepts commands in but does not execute them more than once
7639 * Added silc_net_localhost(), to return local hostname, into
7640 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7641 that must be initialized before calling silc_client_init.
7643 * Added new function: silc_server_send_notify_on_channels to send
7644 notify messages to all channels client has joined. It is assured
7645 that the message is sent only once per client.
7647 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7648 lib/silcutil/silcutil.[ch] as silc_format function. The new
7649 function is generic and is used by server as well, not only by
7650 the logging routines.
7652 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7653 the provided version string was not acceptable. Added new function:
7654 silc_ske_check_version into lib/silcske/silcske.h. The function
7655 must be implemented by the application (client or server) and it
7656 does not reside in the SKE library. The function checks the version
7657 string remote end sent.
7659 * Added back pointers (to opaque context and to SilcSocketConnection)
7660 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7662 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7663 duplicate packet context structure.
7665 * Changed `notify' client operation to send same arguments as client
7666 receives from server except for ID's. ID's are mapped to correct
7667 ID entry and that is returned. Also, if channel entry is not sent
7668 by server but the notify is for channel the channel entry is sent
7669 to application (otherwise application doesn't know that it is for
7670 channel (library gets it from packet's Destination ID)).
7672 * Added silc_client_remove_from_channels into client library to
7673 remove a client from all channels it has joined to. Used when
7674 received SIGNOFF notify from server. Added also new function
7675 silc_client_replace_from_channels to replace old ID entry with
7676 new ID entry on all channels. Used when received NICK_CHANGE
7679 * Fixed ID Cache list handling in silc_idlist_get_client in
7680 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7681 to get (or query) client by ID.
7683 * Updated TODO list.
7685 * Added connection authentication status message defined by the
7686 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7687 support for these into the code in client and server side.
7689 * Added generic function silc_client_send_command to send any command
7690 with variable argument list. Application should use this function
7691 to send commands if the command functions provided by the library
7692 does not suite for the application's user interface needs.
7694 * Added new `failure' client operation. Application is notified about
7695 received failure packet if client is executing a protocol. In this
7696 case the protocol's execution has failed.
7698 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7699 is required by the protocol.
7701 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7702 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7705 * Added status flag to SilcSKE object to indicate realtime status
7706 of the SKE protocol.
7708 * Application receives now exactly same command reply arguments as
7709 the library receives from server. However, if ID is received the
7710 corresponding ID entry is returned to the application (eg. Client
7711 ID is mapped to correct SilcClientEntry entry and that is returned).
7712 Changed command_reply client operation due to this change.
7714 * Changed all ID's in commands and in command replys as ID Payloads.
7715 Change affected both client and server side codes.
7717 All ID's sent in SILC network (with execption of ID's in SILC
7718 Packet header) are sent in ID Payload to support variable length
7721 * Server now notifies nick changes and notifies all clients on
7722 the channels about the new nickname (about the new Client ID,
7725 * Implemented CMODE command to change channel modes. Supports all
7726 channel modes defined by the protocol specs except ban and invite
7727 lists. (Also, private channel key mode is supported but support for
7728 setting private channel key in client is missing, thus, this mode
7729 has no effect on client side (except that server requires that the
7730 client uses private channel key and normal channel traffic does not
7733 Also, invite mode works per se, but INVITE command does not work
7734 yet correctly, so you can set channel as invite only channel but
7735 inviting clients to the channel does not work (it is yet to be
7736 thought what's the best way to do it).
7738 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7739 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7740 Implemented CUMODE command to change user's mode on the channel.
7741 Supports all modes defined by the protocol specs.
7743 * Added NAMES command reply to return users modes on the channel.
7745 * Removed unnecessary and slow ciphers from lib/silccrypt.
7747 * Set SO_KEEPALIVE option to connection sockets by default.
7749 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7751 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7752 redefined the Notify Payload into protocol specs.
7754 * Added silc_id_payload_parse_id to get ID directly from raw
7757 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7759 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7760 accept searching by Client ID as well.
7762 * Added support for LEAVE and SIGNOFF notify types in client library.
7764 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7765 to parse ID Payload from raw data.
7767 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7769 * Added flags parameter into silc_ske_assemble_security_properties
7770 function in lib/silcske/silcske.[ch].
7772 * Changed notify client operation to fit better for notify messages
7773 sent by server. The notify payload received from server is now
7774 passed to the application (after parsing it to SilcNotifyPayload).
7775 It is application's responsibility to retrieve the arguments
7776 from the payload and show the message the way it wants. The message
7777 sent by server is implementation specific.
7779 * Changed public keys to comply with the protocol specification.
7780 Old public keys are not supported anymore and are not compatible.
7782 * Removed nickname from Channel Payload as the latest draft removed
7783 it. The client must resolve the nickname from the NAMES command
7784 reply received when it joined the channel.
7786 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7788 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7790 * Fixed some errors in protocol specification drafts.
7792 * Created lib/silccore/silcnotify.c to implement Notify Payload
7793 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7794 generic payloads described by protocol specifications. The file
7795 includes implementations for ID Payload and Argument Payload.
7797 * Changed Command Payload implementation to use the new Argument
7798 Payload. Changed command_xxxx_payload to command_payload_xxxx
7799 to comply with SILC coding conventions.
7801 * Added suppport for Argument Payload handling in Notify Payload
7802 implementation as protocol requires it. Added the new support
7803 into server and client lib as well.
7805 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7807 * Added support for multiple nicknames on same channel. [n] is
7808 added locally to the nickname if there are more than one same
7809 nicknames on the channel.
7811 * Server now sends all nicknames that matched WHOIS request.
7812 Client also shows the list received from server.
7814 * Added TOPIC command to client side. User can now set and show
7815 current topic on channel.
7817 * Added MOTD command to client and server. Also, server sends the
7818 motd when client connects to the server.
7820 * Changed version strings to comply ISO 8601.
7822 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7824 * Fixed protocol error handling in client library. It should now
7825 cope even if the SKE fails for some reason.
7827 * Made new protocol specification drafts for submitting to IETF.
7829 * Implemented TOPIC command to server in silcd/command.c.
7831 * Added two new notify types into lib/silccore/silcnotify.h:
7832 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7833 notify nickname change and topic setting/change on a channel.
7835 * API change of command_reply operation in client library. The
7836 application gets now the status type received from server as well.
7838 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7840 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7842 * Cras fixed and optimized the packet handling even further and
7843 it should work now. Minor change to the prototype of function
7844 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7846 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7848 * Added new function into lib/silcutil/silcschedule.[ch]:
7849 silc_schedule_with_fd to select() a specified fd. The function
7850 returns after timeout expires or data arrives or goes. The
7851 function is used by packet routines to wait that all data is
7852 received from network.
7854 * Fixed data reading from network in lib/silccore/silcpacket.c.
7855 The code now assures that all data is read from the fd and then
7856 continues packet processing. This was a bug fix since the code
7857 used to drop some data in some circumstances.
7859 * Added new function into lib/silcclient/client.[ch]:
7860 silc_client_start_key_exchange to start key exchange after
7861 connection has been established to server. The code internally
7862 now uses this funtion but its main purpose was to provide it
7863 for applications that perform their own connecting. After
7864 application has created a connection it merely calls this
7865 function to start the key exchange between client and server.
7866 The library takes care of everything else after that.
7868 Updated also lib/silcclient/README to explain the usage of
7871 * Do not send to application information that connection has
7872 been established. Application gets notified it by connect
7875 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7877 * Applied cras's patch to add silc_schedule_one function. The
7878 function runs scheduler once and returns.
7880 * Fixed the scheduler after cras messed it up. The timeout
7881 handling works now as it's supposed to work.
7883 * Added into lib/silccore/ silcnotify.h to include notify
7884 message types support. Changed silc_server_send_notify*
7885 functions, in server.[ch], to support those new notify types.
7886 Added the support for the notify types into client library,
7887 as well. Added new notify client operation into ops.h in
7890 * Changed silc_server_packet_send_to_channel to send normal
7891 packets instead of just channel message packets. The function
7892 is now used to send the notify packets to channels. It is not
7893 used to send channel message packets anymore, as server never
7896 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7897 va_arg()s as it seems to require it nowadays. I guess, if SILC
7898 is compiled with older va_arg() the new code should work anyway.
7900 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7902 * Splitted core library. Core library (lib/silccore) includes
7903 now only SILC protocol specific core (and common) components.
7904 Created new utility library (lib/silcutil) that includes more
7905 generic purpose stuff. The stuff for util library was taken
7906 from the old core library. This was minor and easy split.
7908 * Created SILC Client Library (lib/silcclient) that includes
7909 implementation of the SILC client without user interface. This
7910 was major move from silc/ directory. The code has been changed
7911 so that it is transparent towards the user interface. The
7912 silc/ directory includes now the same user interface as before
7913 and it uses the new client library. Read lib/silcclient/README.
7914 Basicly, the client library performs everything else related
7915 to SILC except user interface handling. Also, configuration
7916 files are considered to be part of user interface and library
7917 does not handle them.
7919 This change also changed a lot of structures, function naming etc.
7920 Most important change was that SilcClientWindow object was
7921 renamed to SilcClientConnection in the client library. Created
7922 also new file lib/silcclient/ops.h. Also added new files
7923 silc/local_command.[ch] and silc/client_ops.[ch].
7925 All these changes were made to make it easier for user interface
7926 designers to create what ever user interface for the SILC client
7929 It is also expected that the server will be moved to lib
7930 directory as well and SILC Server Library will be created;
7931 sometimes in the future.
7933 * Removed Local commands from lib/silccore/silccommand.h as
7934 they are application specific and new client library does not
7935 handle any of those anymore.
7937 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7938 old client implementation in silc/.
7940 * Added support for callback functions in SILC_LOG_* macros.
7941 Application can now set its own callbacks that will be called
7942 instead of using the default functions that will always print
7943 the debug messages to stderr (or stdout). Also, debugging can
7944 now be disabled by setting silc_debug to FALSE and re-enabled by
7945 setting it to TRUE. Note, that logging will still work even
7946 if debugging is disabled.
7948 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7949 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7950 silc_log_reset_debug_callbacks.
7952 * To enable debugging in silc client one must give now -d
7953 option on command line.
7955 * Changed silc_schedule_init to automatically allocate task queues
7956 if they are not allocated before calling it.
7958 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7960 * Added GMP 3.1 into math library.
7962 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7964 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7965 a channel in SILC network. The packet is used by servers and
7966 routers to notify other routers that user has left a channel.
7967 This little feature was missing until now. Added the feature
7968 to protocol specification as well.
7970 Added functions: silc_server_send_remove_channel_user and
7971 silc_server_remove_channel_user into server.[ch].
7973 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7974 lib/silccore/silcpacket.h. However, they are not implemented
7977 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7979 * Fixed joining to a channel and sending channel messages
7980 between server and router. The channel message sending should
7981 now work inside a cell.
7983 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7985 * Fixed the private message sending between server and router.
7986 The private message sending should now work inside a cell.
7988 * Added silc_server_replace_id into server.[ch] to replace
7989 existing ID in the SILC network.
7991 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7992 and silc_idlist_replace_server_id into idlist.[ch] in server.
7994 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7996 * Fixed the server to server connections. Server can again now
7997 connect to router. Router to router connections probably does
8000 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8002 * Added dynamic protocol registering support. Now protocols can
8003 registered and unregistered on the fly. Patch by cras.
8005 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8007 * Added lib/contrib directory to hold routines that some platforms
8008 don't have but are needed by SILC.
8010 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8011 into lin/contrib to provide getopt() and getopt_long() for
8012 those who don't have it.
8014 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8016 * Added AWAY command to client. When away message is set and
8017 client receives a private message packet the client automatically
8018 replies to the sender with the away message.
8020 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8021 bug seemed to be the cause of recent problems when compiling
8024 * Added version detection support to SKE protocol specification
8025 and added the new changes to the SKE implementation as well.
8026 There were other minor changes in the SKE protocol as well.
8028 Many changes in lib/silcske/silcske.[ch] and in
8029 lib/silcske/payload.[ch].
8031 * Added ^U functionality, clear input line. Patch from cras.
8033 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8035 * Mainly small bugfixes on core library. Fixed some debugging
8036 logging and buffer overflow in silclog.c.
8038 * Updated config.sub and config.guess on the distribution tree.
8040 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8042 * Added command lagging support in server. Client may execute
8043 commands now only once in two seconds.
8045 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8047 * Optimized packet reception. MAC computation and checking is now
8048 also more optimized. A lot previously duplicated code is now
8049 used as generic by both client and server.
8051 * Fixed key pair generation in clientutil.c
8053 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8055 * Added into lib/silccore/silcbufutil.[ch] new function;
8056 silc_buffer_realloc.
8058 * Moved generic packet sending/encryption functions to
8059 lib/silccore/silcpacket.[ch] from client and server. Some
8060 rewriting of the functions.
8062 * Moved all generic packet reception/decryption functions to
8063 lib/silccore/silcpacket.[ch] from client and server. The
8064 packet processing is now much cleaner in both client and server.
8065 These were major changes in both client and server.
8067 * Created many common functions in server to do packet sending.
8068 Previously code were duplicated a lot, this has been removed
8071 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8073 * Rewrote major parts of the ID cache system. Don't know
8074 whether it is better now or not but at least the API is more
8077 * Major rewrite on ID cache stuff on client because of the ID
8078 cache API changes. Added idlist.c to client.
8080 * Also major rewrite on ID cache stuff on server as well.
8081 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8082 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8083 in hand, instead they are all put into the ID cache system now.
8084 All server_idlist_* routines uses ID cache now instead of
8085 traversing its own lists (those lists does not exist anymore).
8086 SilcIDList though still exists. Also, SilcXXXEntry's are
8089 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8091 * Finally made the SKE implementation compliant to the protocol
8092 specification. All mp integers are now binary encoded as
8093 opposed being HEX encoded.
8095 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8098 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8099 functions: silc_[encode/decode]_pem. Also added function
8100 silc_encode_pem_file to PEM encode with newlines ('\n') for
8103 * SILC public keys are now encoded either PEM or binary. Same
8104 option is for private keys as well. By default private keys
8105 are binary encoded and public keys PEM encoded. Silly HEX
8106 encoding were removed.
8108 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8109 function to create fingerprints.
8111 * Fixed a bug in SHA1; does not change the original data anymore.
8113 * Partly implemented INFO command on client and server side.
8114 Fixed CLEAR command. Changes to SERVER command; show current
8115 server(s) when giving command without arguments. Added
8116 VERSION command to client.
8118 * Added check to server that unregistered connections cannot
8119 execute commands (unless it is specificly allowed).
8121 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8123 * Fixed screen refresh.
8125 * Fixed channel joining bug from client. On some circumstances
8126 client tried to join to a channel it had already joined.
8128 * Added public key verification process into client's protocol.c.
8129 The client now verifies the public key from user and saves
8130 it into ~./silc/serverkeys/ directory.
8132 Added into: clientutil.[ch]: silc_client_verify_server_key.
8134 * Changed SKE protocol's silc_ske_initiator_finish function
8135 to accept callback function that verifies the received public
8136 key. Removed old silc_ske_verify_public_key function.
8138 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8140 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8141 silc_pkcs_private_key[_data]_set.
8143 * Made the password and public authentication more cleaner in
8144 server's protocol.c.
8146 * Removed historic and obsolete protocol `channel_auth' from
8147 both client and server.
8149 * Removed wrong way of sending command status messages from
8150 server to client in server's command.c. The old way violated
8151 protocol specification.
8153 Changes to silccore/silccommand.[ch]: removed
8154 silc_command_encode_status_payload -> not needed anymore,
8155 changed silc_command_encode_payload_va to accept extra
8156 argument on variable argument list. The argument type must
8157 now be provided to the function. Also, added new function:
8158 silc_command_encode_reply_payload_va which is same as
8159 normal command_encode_payload_va except command status type
8160 is provided as extra argument.
8162 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8164 * Added ~./silc directory handling. The directory includes the
8165 public and private keys for the client.
8167 Added silc_client_check_silc_dir, silc_client_create_identifier
8168 and silc_client_load_keys.
8170 * Implemented SILC protocol compliant public key. Added public
8171 and private key saving to and loading from files.
8173 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8174 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8175 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8176 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8177 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8179 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8180 silc_pkcs_load_[public/private]_key.
8182 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8184 * Added silc_server_get_route (route.[ch]) to get connection
8185 data for the fastest route for given ID.
8187 * Implemented INVITE command on client and server. The command
8188 were re-defined in the SILC Protocol Specification and the
8189 implementation now complies with the specification.
8191 * Implemented PING command on client and server.
8193 * Implemented NAMES command on client and server. The server side
8194 supports currently only normal server not router server yet.
8195 Some changes to NAMES definition in SILC protocol specification.
8197 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8199 * Implemented LEAVE command on client and server.
8201 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8202 again. This change was made to the protocol as well. Server
8203 should not violate the protocol specification anymore.
8205 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8207 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8208 was tested. SOCKS4 was not but should work anyway.
