3 * Fixed a bug in library where sending a bogus authentication
4 payload would lead to a crash. Affected file is
5 lib/silccore/silcauth.c.
7 Sat Apr 13 13:09:24 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
9 * Added detach_disabled and detach_timeout server config
10 options to the server. Affected files silcd/serverconfig.[ch],

15 * Added resolve_cmd_ident field to the SilcClientEntry structure
16 too so that if the entry is for example being resolved so
17 another command may attach to the same pending command reply
18 without requiring to resolve the same entry again. Added
19 support for adding multiple pending commands for one
20 command idenfier. Affected files lib/silcclient/command.[ch],
21 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
23 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
25 * Defined that server receives WHOIS command reply for private
26 and secret channels too. Updated protocol specs and the
27 code in server. Affected file silcd/command.c.
29 * Defined <channel user mode list> argument to WHOIS command
30 reply for returning user modes on the channels. The
31 channel list now doesn't include the user mode anymore but the
32 actual channel mode. Updated protocol specs and the code in
33 client and server. Affected files are silcd/command_reply.c,
34 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
35 and lib/silcclient/command_reply.c.
37 * Save the channels list in WHOIS command reply in normal server
38 so that WHOIS always shows joined channels also in normal
39 server and not just on router. Affected file is
40 silcd/command_reply.c.
42 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

48 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
50 * Changed the UMODE's mode mask argument to be optional. If
51 not provided then the command merely returns the current mode
52 mask to the client. Updated protocol specs and the server.
53 Affected file is silcd/command.c.
55 * Added SILC session detachment/resuming support. It is possible
56 to detach by closing the network connection and then re-connect
57 and resume to the old client session. Added DETACHED user
58 mode that server will set for detached client. Added new
59 packet RESUME_CLIENT which is used to perform the resuming
60 process. Added DETACH command. Updated the protocol specs,
61 core library, client and server. Protocol TODO #22. Very
62 many affected files around the tree.
64 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
66 * Changed the CMODE's mode mask argument to be optional. If
67 not provided then the command merely returns the current mode
68 mask to the client. Updated protocol specs and the server.
69 Affected file is silcd/command.c.
71 * Changed the Killer's Client ID in KILLED notify to be just
72 any ID payload since router server is allowed to kill as well.
73 Updated protocol specs, client libary and server. Affected
74 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
75 and irssi/src/silc/core/client_ops.c.
77 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
79 * Added new user modes ANONYMOUS for special anonymous servers
80 that may set the mode for client, and BLOCK_PRIVMSG which
81 client may set to block incoming private messages unless the
82 Private Message Key flag is set (using private keys to protect
83 private messages). Updated protocol specs and code in client
84 and server and core library. Protocol TODO #23. Affected
85 files are lib/silccore/silcmode.h, silcd/server.[ch],
86 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
87 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
89 * Added new channel user mode BLOCK_MESSAGES which the client
90 may set to itself to tell server not send channel messages.
91 Other packets such as channel key packets are still sent.
92 Protocol TODO #23. Updated the protocol specs, client and
93 server. Affected files are lib/silccore/silcmode.h,
94 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
95 lib/silcutil/silcutil.c, silcd/command.c, and
98 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
100 * Redefined the Status Payload to include now two 8 bit fields,
101 instead of one 16 bit field. This now makes it possible to
102 send list of errors. Updated the protocol specs and the code
103 in core library, client library and server. Protocol TODO #1.
104 Affected files are lib/silccore/silccommand.[ch],
105 lib/silcclient/command_reply.[ch], silcd/command.c,
106 silcd/command_reply.c and silcd/packet_receive.[ch].
108 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
110 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
111 must be handled by the application and should tell the application
112 that an error message was already printed, and it should print the
113 config coords (line, filename, ...). Affected files are
114 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
116 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
117 server config parsing code more readable.
119 Fixed a bug in the fetch_logging() config callback.
121 Affected files is silcd/serverconfig.c.
123 * Drop root privileges when started in foreground. Don't drop them
124 if debugging also. Affected file is silcd/silcd.c.

132 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
133 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
135 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
137 * Added STATS command to the protocol after all, to return
138 various statistical information about the network. It can
139 be used by clients to retrieve statistical information, and
140 servers may use it to to fetch cell and network wide
141 statistics from router. Updated the protocol specs and
142 implemented it to the server. Protocol TODO #16.
143 Affected files are lib/silccore/silccommand, silcd/command.[ch],
144 silcd/command_reply.[ch].
146 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
148 * The LIST command reply in client libary now adds new channel
149 entry if the returned channel doesn't exist yet in cache,
150 and returns the channel entry to the application in the
151 command_reply client operation. Affected file is
152 lib/silcclient/command_reply.c.
154 * Changed the channel message payload's MAC generation to
155 include the IV in the MAC as well. This way all relevant
156 parts of the channel message payload are authenticated also
157 with the channel message MAC (and not only by packet MAC).
158 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
159 Affected file is lib/silccore/silcchannel.c.
161 * Fixed the SKE to save the remote version, since the
162 silc_ske_parse_version mistakenly checked wrong version,
163 after it replaced the start payload. Affected files are
164 lib/silcske/silcske.[ch].
166 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
168 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for

170 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
171 Affected files lib/silcutil/silcstrutil.[ch].
173 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
174 files are lib/silcutil/silcstrutil.[ch].
176 * Defined that the security property fields in SKE SHOULD be
177 UTF-8 encoded, defined that version string MUST be US-ASCII
178 encoded, defined that passphrases sent in connection
179 authentication protocol MUST be UTF-8 encoded. Implemented
180 these to the client and server. Defined also that other
181 passphrases sent in the protocol MUST be UTF-8 encoded.
182 Affected files are lib/silcske/silcske.c,
183 lib/silcclient/protocol.c, silcd/protocol.c,
184 silcd/serverconfig.c, and lib/silccore/silcauth.c.
186 * Changed the silc_client_close_connection interface to not
187 need the SilcSocketConnection which should not be visible
188 to application. Affected files are lib/silcclient/client.c
189 and lib/silcclient/silcclient.h.
191 * Rewrote the text for Private Message Key Payload in the
192 protocol specification. Protocol TODO #11.
194 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
196 * Upgraded the protocol version to 1.1, updated protocol specs

207 Protocol TODO #13. Affected files are silcd/command.c,
208 silcd/packet_receive.c, packet_send.[ch],
209 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
210 The killer's client entry is now returned to application in
211 the `notify' client operation.
213 * Fixed the Max Argument fields that had too large value set
214 in the protocol specs. Protocol TODO #14.
216 * Added the LEAVE command reply to return the ID of parted
217 channel. Updated protocol specs and implemented it to the
218 client and server. Protocol TODO #15. Affected files are
219 silcd/command.c, lib/silcclient/command_reply.c. The channel
220 entry is now returned to application in the `command_reply'
223 * Rewrote the version SKE version checking in client libary
224 and in server to use the silc_parse_version_string. Affected
225 files are lib/silcclient/protocol.c, silcd/protocol.c.
227 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
228 commands that was missing it, and updated protocol specs and
229 the server implementation. Protocol TODO #10. The affected
230 file is silcd/command.c.
232 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
233 generic reply to a generic request (REQUEST flag), and
234 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
235 way. A draft-riikonen-silc-flags-payloads-00.txt is written
236 to define the payload for DATA flag. Added the flags to
237 the implementation. Protocol TODO #9. Affected file is
238 lib/silccore/silcchannel.h.
240 Changed the client library to return the message length
241 to application as well in the channel_message and private_message
242 client operations. Affected files are
243 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
244 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
245 and lib/silcclient/client_ops_example.c.
247 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
248 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
249 the channel. Updated protocol specs and impelemented this
250 to client and server. Protocol TODO #6. Affected files are
251 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

254 Added new options m and M to CMODE command in Irssi SILC
255 client to set these modes.
257 * Deprecated all administrative commands from SILC protocol
258 since they are highly implementation specific commands.
259 Updated protocol specs. Moved the old commands in
260 implementations to private range of command types. Affected
261 files are silcd/command.c, lib/silcclient/command.c and
262 lib/silcclient/command_reply.c. Protocol TODO #8.
264 * Fixed a bug in server where sending unknown command crashes
265 the server. Affected file silcd/command.c.
267 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
269 * Added SILC_PROTOCOLVERSION macro to check protocol version
270 of a socket connection. The affected file is
271 lib/silcutil/silcsockconn.h.

280 Affected file silcd/protocol.c.
282 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
284 * Some client implementations quit network by doing first LEAVE
285 and then immediately SIGNOFF (like Bombyx). We now do check
286 after a short time after LEAVE notify and check whether the
287 client is still valid after LEAVE, and if not we remove it from
288 cache. Affected file is lib/silcclient/client_notify.c.
290 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
292 * Merged version 1.1.4 of zlib. Even if it not currently in use,
293 it's good not to have security holes here.
295 * Fixed a negative refcount situtuation for the config context.
296 Affected file is silcd/serverconfig.c.
298 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
300 * ROBOdoc documented lib/silcutil/silcutil.h.
302 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
304 * Optimized even more the SilcPacketContext structure. Now
305 totally saved 16 bytes of memory per context after optimization.
306 Affected files are lib/silccore/silcpacket.[ch].
308 * Made strict checks for valid SILC IDs. Affected file is
309 lib/silccore/silcid.c.
311 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>

316 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
318 * Changed the silc_get_username and silc_get_real_name to
319 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
321 * Fixed the Irssi SILC Client to use the silc_get_username and
322 silc_get_real_name insted of glib routines since the glib
323 routines only corrupt stack. Fixes the Irssi SILC to work in
324 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
326 * Fixed the Irssi to not use g_get_home_dir since it crashes
327 or returns garbage on cygwin and corrupts stack. Added function
328 get_home_dir to Irssi routines. Affected files are
329 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
331 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
333 * Made some structure optimizations. SFTP memory FS MemFSEntry
334 entry structure. Optimized SilcTask structure. Optimized
335 SilcPacketContext structure.
337 Affected files lib/silcsftp/sftp_fs_memory.c,
338 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
340 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
342 * And yet again reverted back the config thing since Johnny
343 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
346 * Fixed memory leaks from config object. Affected files are
347 silcd/serverconfig.[ch].
349 * Added support for adding new connections to the server in rehash.
350 After rehash they take effect.
352 Added support for changing the maximum allowed connections in
353 rehash. The number can grow but going smaller is not supported.
355 Added function silc_server_num_sockets_by_remote to the
356 silcd/server_util.[ch].
358 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
360 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
362 * Added preliminary checking during config parsing for a valid
363 public/private key and removed further checks in the code.
364 Affected files are silcd/serverconfig.[ch], server.c.
366 * Moved functions silc_server_drop() and silc_server_daemonise()
367 from server.c to silcd.c since they are stricly related to
368 the application activity.
370 * Reverted a small part of the automatic ref/unref since
371 it caused a double unref in some situations. Affected
372 files are silcd/silcd.[ch], server.c, serverconfig.c.
374 * Added some .cvsignore files in the lib directory.
376 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
378 * Fixed silc_net_gethostbyaddr to correctly resolve by
379 address. Affected file lib/silcutil/silcnet.c.
381 * Fixed the notify relaying to client. The HMAC to be used
382 with relayed packets ws wrong and caused decryption failure
383 at the client end. Affected file is silcd/packet_receive.c.
385 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
387 * Created new branch silc_protocol_1_0_branch.
389 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
391 * Changed the silc_server_config_* routines to be SilcServer
392 independent. They are now officially application specific code
393 and not part of generic server implementation. Affected files
394 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
396 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
398 * Added automatic referencing of config context in the
399 silc_server_config_alloc, and automatic unreferencing in the
400 silc_server_config_destroy. Affected files are
401 silcd/serverconfig.[ch], silcd/silcd.c.
403 * Fixed the silc_log_quick handling in the logging routines.
404 It didn't log quickly when it was TRUE. Affected file is
405 lib/silcutil/silclog.c. Also the flush delay was set even
406 if it was 0 in config file. Affected file is
407 silcd/serverconfig.c.
409 * Added support for changing key pair of the server in rehash.
410 Affected file silcd/server.c.
412 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
414 * Fixed the TOPIC_SET notify to not cras. It changed the topic
415 too early, before getting the channel entry. Affected file
416 is silcd/packet_receive.c.
418 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
420 * Added functions silc_server_config_[ref/unref], these are used
421 to prevent that the config object is destroyed.
423 No longer directly affect global variables silc_log_quick and
424 silc_log_delay, they are first cached inside the config object
425 and then applied with silc_server_config_setlogfiles().
427 silc_server_config_set_defaults() is now internal to
428 serverconfig.c, there are no reasons to show this internal stuff
431 Affected files are silcd/serverconfig.[ch].
433 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
434 fprintf's to stderr, since some code may be executed again after
435 the server went into the background. Affected files are
438 * Added rehash support. Added function silc_server_rehash() that
439 will perform all the basic tasks of the rehashing procedure.
441 * Added command line option `-x, --hexdump'. This will enable the
442 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
443 The option `--hexdump' implies `--debug'.
445 * Fixed a bad bug in the logging APIs (silcutil library) where
446 the application would crash after calling silc_log_reset_all().
448 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
450 * Fixed the KICKED notify handling in client library to
451 correctly remove the channel and all entries from the
452 channel when I was kicked. This bug crashed the client.
454 Fixed yet another but in KICKED notify handling to remove
455 the kicked client correctly from the channel.
457 Affected file is lib/silcclient/client_notify.c.
459 * Fixed a minor bug in looking up correct client entry
460 in KICKED notify in server. Affected file is
461 silcd/packet_receive.c.
463 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
464 sources correctly to distribution. Fixes --with-gmp option.
466 * Removed the manual rehashing from ID Cache, and changed it
467 to use the SILC Hash Table's auto rehash feature. Affected
468 file is lib/silccore/silcidcache.c.
470 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
472 * Fixed a bug in the silc_client_nickname_format function that
473 handles the multiple same nickname formatting. Two clients
474 with same nickname caused problems after the first one left
475 and rejoined. It didn't format the nickname correctly.
476 Affected file is lib/silcclient/idlist.c.
478 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
480 * Don't change the topic if olod topic is same as new one.
481 Affected file is silcd/packet_receive.c.
483 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
485 * Added cross-reference support to the SILC Documentation
486 generator. All types across all HTML files are now cross-
487 referenced. Affected files util/robodoc/generator.c and
488 scripts/silcdoc/silcdoc.
490 * Added file lib/silcutil/silctypes.h to include all the
491 arithmetic type definitions and some macros. Removed
492 includes/bitmove.h and moved macros to silctypes.h.
494 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
496 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

501 now returns the type of the ID to the sent pointer. Affected
502 file is lib/silccore/silcid.[ch].
504 * Added check for CMODE_CHANGE notify type that mode change is
505 allowed by the sender. Affected file silcd/packet_receive.c.
507 * Added check for CUMODE_CHANGE notify type that mode change is
508 allowed by the sender. Affected file silcd/packet_receive.c.
509 Added the ID type as CUMODE_CHANGE notify type as argument
510 to the `notify' client operation. Affected files are
511 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
513 * Added function silc_client_add_server to the client library.
514 Added support for resolving also channel and server info when
515 received unknown entity in notify packet. Affected files are
516 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
518 * Added function silc_command_get_status to return the command
519 status from the command reply's argument payload. Affected files
520 are lib/silccore/silccommand.[ch].
522 * Added check for KICKED notify type that the kicking is
523 allowed by the client. Affected file silcd/packet_receive.c.
525 * Created function silc_get_input which can be used to get input
526 (echo on or off) from user on command line. Affected files are
527 lib/silcutil/silcutil.[ch].
529 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
531 * Optimized silc_server_packet_relay_to_channel function.
532 Added new function silc_channel_message_payload_encrypt which
533 can be called directly if channel message payload needs to
534 be encrypted and is already encoded (no need to call _encode
535 function). Packet relaying is now done by router without any
536 extra memory allocations. Affected files are
537 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
540 * Fixed the INVITE notify handling. It took wrong arguments
541 as invite list and invite delete. Affected file is
542 silcd/packet_receive.c.
544 * Added check for TOPIC_SET notify type that the topic change is
545 allowed by the client. Affected file silcd/packet_receive.c.
547 * Added check for INVITE notify type that inviting is allowed by
548 the client. Affected file silcd/packet_receive.c.
550 * Changed the silc_server_client_on_channel to return the
551 SilcChannelClientEntry as well. Moved the function
552 silc_server_check_cmode_rights to server_util.[ch].
553 Affected files are silcd/server_util.[ch], silcd/command.c.
555 * Added function silc_server_check_umode_rights to check whether
556 changing client's user mode is allowed. Added check for
557 UMODE_CHANGE notify type that the umode change is allowed
558 by the client. Affected files are silcd/server_util.[ch],
559 silcd/packet_receive.c and silcd/command.c.
561 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
563 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
564 ID length. It ignored that ID can be IPv6 based as well.
565 Affected file lib/silccore/silcpacket.h.
567 * Fixed the silc_id_id2str and silc_id_str2id to take the
568 IPv6 address offset's into consideration. Affecte file is
569 lib/silccore/silcid.c.
571 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
573 * Fixed the internal Unix scheduler functions to check for
574 NULL context they may receive. The affected file is
575 lib/silcutil/unix/silcunixschedule.c.
577 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
579 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
580 can specify different directory with --home command line
581 parameter. Affected files irssi/src/silc/core/client_ops.c,
584 * SILC-specific commands aren't now executed if the active server
585 isn't of SILC-type, so there won't be problems with having
586 IRC and SILC protocol support in same client. Affected files
587 irssi/src/silc/core/silc-channels.c, silc-servers.c,
590 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
592 * Improved the signal support in SILC Schedule. Added new
593 function silc_schedule_signal_call which is used by application
594 to mark a signal to be called. It is now safe to perform
595 any kind of tasks in signal callbacks since it is guaranteed
596 that the application specified signal callback is called
597 after the signal is over. Affected files are
598 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
600 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
602 * Added `name' field to SilcChannelPrivateKey to represent
603 application given name for the key. Moved also the context from
604 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
605 Added the `name' argument also to the function
606 silc_client_add_channel_private_key.
608 Added function silc_client_current_channel_private_key to set the
609 current channel private key in use.
611 Added "change" command to KEY command which can be used to change
612 the current channel private key. Bound the command also to
615 Also affected files lib/silcclient/client_channel.c,
616 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
618 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
620 * Added silc_rng_get_byte_fast function in to the
621 lib/silccrypt/silcrng.[ch].
623 * Changed the interface of silc_packet_assemble and the
624 silc_packet_send_prepare. If silc_packet_assmble is now
625 called the application does not call silc_packet_send_prepare
626 because the library will call it automatically. These
627 interfaces now also return a reference to the outgoing buffer
628 which includes the assembled packet, which the application can
629 use to encrypt the packet.
631 Affected files are lib/silccore/silcpacket.[ch],
632 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
633 silcd/packet_send.c, server_backup.c and packet_receive.c.
635 * Fixed a packet sending bug on very high load, where outgoing
636 packet queue wasn't handled correctly and packets got corrupted.
637 Affected files are lib/silcutil/*/silc*sockconn.c,
638 lib/silcclient/client.c and silcd/server.c.
640 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
642 * Added macro SILC_PACKET_DATALEN which can be used during
643 packet assembling to check whether the data to be added to
644 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
645 len is truncated until it fits it.
647 Added checks for maximum length of channel message payload and
648 private message payload also.
650 Added checks for maximum packet length in server and in
653 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
654 lib/silcclient/client.c, lib/silccore/silcchannel.c and
655 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
656 lib/silcclient/client_prvmsg.c.
658 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
660 * Added silc_server_packet_queue_purge call to the
661 silc_server_disconnect_remote to assure that all data in the
662 queue before disconnecting is sent to the network. Affected
665 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
667 * Added the deleting of server's own ID cache entry to the
668 silc_server_free function. Free also everything else that
669 has been allocated in silc_server_init. The affected file
672 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
674 * Added functions silc_parse_version_string, silc_version_to_num,
675 and silc_ske_parse_version to parse SILC protocol style version
676 strings. Affected files lib/silcutil/silcutil.[ch] and
677 lib/silcske/silcske.[ch].
679 * Added new configuration params: version_protocol, version_software
680 and version_software_vendor to specify what version the remote
681 host must at least be to be able to connect to server. The vendor
682 string can be regex matched too. Added new function
683 silc_server_connection_allowed to check maximum number of allowed
684 connections, and allowed versions for incoming connections.
685 Affected files are silcd/server.c, server_util.[ch] and
688 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
690 * Added preliminary support for signals in scheduler. The
691 signals we care about are now blocked always when the scheduler
692 is locked. This way we can synchronise the use of signal with
693 scheduler. It is guaranteed that when signal occurs the scheduler
694 is not locked, and thus new tasks can be safely added to the
697 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
698 to silc_schedule_internal_init and silc_schedule_internal_uninit.
699 Added new platform specific routines
700 silc_schedule_internal_signals_[un]block and
701 silc_schedule_internal_signal_[un]register.
703 Added new functions to SILC Schedule API:
704 silc_schedule_signal_[un]register. Each signal that application
705 is going to use should be registered to the scheduler.
707 Affected files are lib/silcutil/silcschedule.[ch],
708 lib/silcutil/*/silc*schedule.c.
710 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
712 * Check for unauthenticated client and server in the
713 silc_server_new_client and silc_server_new_server functions.
714 Affected file silcd/packet_receive.c.
716 * Added function silc_string_is_ascii to check whether given
717 string is 7-bit ASCII string. Affected files are
718 lib/silcutil/silcutil.[ch].
720 * Added function silc_id_is_valid_server_id into the
721 silcd/serverid.c and added checking for valid Server ID's in
722 silc_server_new_server. The Server ID must always be based
723 on the server's public IP address.
725 * Added logging of DISCONNECT packet message in the server.
726 Affected file silcd/server.c.
728 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
730 * Changed all library interfaces that use Global RNG to also
731 accept SilcRng as argument. Affected files are
732 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
733 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
734 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
735 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
738 * Added function silc_pkcs_generate_key to the
739 lib/silccrypt/silcpkcs.[ch] for applications so that they
740 don't need to do pkcs->pkcs->init calls anymore.
742 * Remove SilcSocketConnection from the SFTP API since it really
743 wasn't needed there. The application has the information
744 saved in its contexts anyway and the SFTP layer doesn't need
745 know about it. Affected files lib/silcsft/silcsftp.h and
746 lib/silcsftp/sftp_[server/client].c.
748 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
749 The SilcSimContext is not SilcSim.
751 * Fixed possible buffer overflows in silc_id_render in the
752 lib/silcutil/silcutil.c.
754 * On EPOC the global crypto module lists are not used at all
755 in the crypto library. Added support for using the constant
756 algorithm list on EPOC. Affected files are
757 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
760 * Fixed the handling of third parameter of KICKED notify, since
761 it was mistakenly updated to SILC Protocol 1.0 even though it
762 is to be included in 1.1. Since it is not in 1.0 it is not
763 mandatory, and this fix now handles it only if it is provided,
764 and it is not error if it is not provided. Affected file
765 lib/silcclient/client_notify.c.
767 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
769 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
770 client. Affected file irssi/src/silc/core/client_ops.c.
772 * Merged with Irssi 0.8.4 from irssi.org CVS.
774 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
776 * Check for valid socket connection in client entries before
777 sending any messages. Fixes a crash, but doesn't fix some
778 other underlaying bug that is lurking there. Affected
779 file silcd/packet_send.c.
781 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
783 * $usermode, $cumode and $cumode_space expandos shouldn't do
784 anything with non-SILC server records. Affected file
785 irssi/src/silc/core/silc-expandos.c
787 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
789 * Fixed the silc_net_check_[host/local]_by_sock to support
790 IPv6 bound sockets as well. Now they can return IPv6 addresses
791 as well. Affected file lib/silcutil/silcnet.c.
793 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
794 Affected lib/silcutil/unix/silcunixnet.c.
796 * Fixed ID rendering (at least on some platforms, not NetBSD)
797 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
799 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
801 * Added silc_hash_public_key and silc_hash_public_key_compare
802 functions to be used with SilcHashTable. They can be used to
803 hash public keys and compare public keys in hash table. Affected
804 file lib/silcutil/silcutil.[ch].
806 * Added support for specifying multiple public keys for Client
807 connection section in server configuration file. This makes it
808 possible to accept multiple public keys from same host, or to
809 make a section that accepts any incoming host, and have the
810 accepted public keys listed in the section.
812 Added functions silc_sever_[find/get]_public_key, added the
813 support for this actually to all connection sections but only
814 the Client section is currently allowed to specify multiple
817 Affected files are silcd/server.c, server_internal.h,
818 command.c, protocol.c, server_util.[ch], packet_receive.c.
820 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
822 * Merged Irssi 0.8.2 from irssi.org CVS.
824 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
826 * If silc_debug is TRUE, also output standard logging messages
827 to stderr with the debug output.
829 Made silc_log_reset_all() flushing all channels before returning.
830 Also fixed some documentation typos.
832 Affected files are lib/silcutil/silclog.[ch].
834 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
836 * Fixed the server to check correctly the amount of connections
837 from single host, by checking also the type of the connection.
838 Fixed also the comparison of number of connections and number
839 of allowed connections. Affected files are silcd/server.c,
842 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
844 * Fixed the USERS command reply to save the user's mode on the
845 channel as well. Fixed JOIN command reply to check whether a
846 client is on channel already and not join it twice. Affected
847 file lib/silcclient/command_reply.c.
849 * Added new file silc-expandos.c into irssi/silc/core/ to return
850 various stuff for various signal for the statusbar etc. updating.
851 Now Irssi SILC client prints channel user modes etc. on the
854 * The user mode (like server/router operator changes) is now shown
855 on the Irssi SILC client's statusbar. The affected files are
856 irssi/src/silc/core/client_ops.c, silc-expandos.c.
858 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
860 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
861 to SILC_SCHEDULE_[UN]LOCK macros.
863 * Added more error printing to logs in server code. Affected
864 files silcd/server.c and silcd/protocol.c.
866 * Fixed -S option parsing in Irssi SILC Client. Affected file
867 irssi/src/silc/core/silc-core.c.
869 * Added silc_buffer_alloc_size function. Affected file is
870 lib/silcutil/silcbuffer.h.
872 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
874 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
875 constants. Affected files in
876 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
879 * Changed the internal SFTP Memory FS table to const. Affected
880 file lib/silcsftp/sftp_fs_memory.c.
882 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
884 * Fixed the buffer formatting and unformatting routines to
885 check the size of 64 bits types with sizeof(). Affected
886 file is lib/silcutil/silcbuffmt.c.
888 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
890 * Removed 0.6.x backwards support.
892 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
894 * Changed all integer type names:
895 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
896 to avoid collisions with other libraries using same type names
899 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
901 * Added `prefer_ipv6' argument to the functions
902 silc_net_gethostbyname[_async]. If it is TRUE it will return
903 IPv6 address over IPv4. If FALSE IPv4 address is returned
904 even if IPv6 address was found. Affected files
905 lib/silcutil/silcnet.[ch].
907 * Added support silc_net_create_connection[_async] to fallback
908 to IPv4 address if IPv6 address could not be used (like if
909 it doesn't work on a specific system). Affected file in
910 lib/silcutil/unix/silcunixnet.c.
912 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
914 * Added silc_schedule_reinit function to do the enlarging
915 of the max tasks handling capabilities of the scheduler.
916 Affected files lib/silcutil/silcschedule.[ch].
918 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
920 * Added automatic extern "C" { ... } for C++ compilers so the
921 application does not need to define them. Affected file
922 includes/silcincludes.h.
924 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
925 old name went against naming convention. Applications now
926 include "silcclient.h" instead of "clientlibincludes.h".
927 Removed includes/clientlibincludes.h, it is redundant now.
929 * Renamed includes/version.h to silcversion.h.
931 * Added really preliminary support for OS/2 into the util
932 library. Only thread & mutex API is implemented, others
933 are still to be implemented. Created the lib/silcutil/os2/
934 directory. Created also file includes/silcos2.h.
936 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
938 * Added preliminary BeOS support into the util library.
939 Created lib/silcutil/beos/, and implemented all the needed
940 functions to support SILC on BeOS. Created also file
943 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
945 * Added proper initializations to silc's irssi code, so it's
946 now possible to load it as module. Affected files
947 irssi/src/silc/core/silc-core.c,
948 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
950 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
952 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
955 * Fixed the silcdoc document generator to correct generate
956 docs from all kinds of filenames. Affected files are
957 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
959 * ROBOdoc documented lib/silcutil/silcmemory.h.
960 Added also new function silc_memdup.
962 * Removed lib/silcutil/silcbufutil.h and moved those routines
963 to the lib/silcutil/silcbuffer.h.
965 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
967 * Added `user_count' to the SilcChannelEntry which now tells the
968 number of users on the channel. The user count is now saved
969 in normal server of global channels as well. Affected files
970 silcd/server.c, idlist.h, packet_receive.c and command.c.
972 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
973 include file utility functions.
975 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
976 instead of calling directly OS routines.
978 * Fixed NICK change printing in Irssi SILC Client. Fixed
979 KICKED notify printing in Irssi SILC Client. Affected file
980 irssi/src/silc/core/client_ops.c.
982 * Fixed a NICK change bug in client library, to not recreate the
983 client_entry->channels hash table everytime nick is changed.
984 Affected file lib/silcclient/client.c.
986 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
988 * ROBOdoc documented the lib/silcske/silcske.h, and improved
989 the SKE interface a bit.
991 * Fixed padding problem in PKCS#1. The padding was not actually
992 random since the random number generator was used incorrectly.
993 This security bug affects only when encrypting with PKCS#1, and
994 it is not currently used at all in SILC. SILC only use signing
995 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
997 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
999 * Rewrote the notify handling in Irssi SILC client to not call
1000 the events as signals. Fixes problems with Perl support.
1001 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1003 * Send the auto-nicking NICK command in client library with
1004 little timeout after connecting. The affected file is
1005 lib/silcclient/client.c.
1007 * Added following new config file settings:
1008 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1009 key_exchange_timeout, conn_auth_timeout, connections_max,
1012 Implemented all the new config settings handling in the server.
1014 Optimized the use of SKE Mutual flag usage. Use it only
1015 if connection authentication protocol is not based in public
1018 Renamed all SilcServerConfigSection* to SilcServerConfig*
1019 to have a bit shorter names.
1021 Affected files silcd/serverconfig.[ch], server.[ch], and
1024 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1026 * Cleaned up the listening sockets code, preparing for the rehash
1027 support. Affected file is silcd/server.c.
1029 * Fixed some output messages. Affected files are silcd/silcd.c,
1032 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1034 * Create lib/doc/silcrng_intro.html document as introduction
1035 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1037 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1039 * Fixes to the silcd config template. Affected file is
1040 doc/example_silcd.conf.in.
1042 * Removed type casts from silc_calloc(), conforming to the
1043 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1045 * Removed param_name member from client, server, and router
1046 section structs, now identifying the param directly.
1048 Added CONFIG_FREE_AUTH macro in config file parsing.
1050 Affected files are silcd/serverconfig.[ch].
1052 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1054 * Fixed command line parameter handling. All SILC initialization
1055 is now done in silc_core_init() which also fixes autoconnecting
1058 Affected files irssi/src/silc/core/silc-core.c,
1059 irssi/src/fe-text/silc.c.
1061 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1063 * Added new configuration options and blocks:
1064 keepalive_secs, reconnect_count, reconnect_interval,
1065 reconnect_interval_max, reconnect_keep_trying and
1066 require_reverser_lookup. Added ConnectionParam block, and
1067 implemented the connection parameters when connecting as
1068 initiator and when accepting connections as responder.
1070 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1071 whether given configuration value has been given already.
1073 Affected files silcd/serverconfig.[c], server.[c].
1075 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1076 algorithm parts and created new file silcalgs.conf, that
1077 is now included from the example_silcd.conf.in.
1079 * Optimized the silc_server_connect_to_router_second to take
1080 the connection configuration object from the SilcServerConnection
1081 object instead of finding it during the connecting phase.
1082 Added the configuration object to SilcServerConnection struct.
1083 Affected files silcd/server_internal.h, server.c.
1085 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1087 * Add the client on channel after it was resolved at the
1088 channel message receiving, and it was not already on the
1089 channel. Affected file lib/silcclient/client_channel.c.
1091 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1093 * Fixed the public key authentication to allocate always the

1105 * Added new Passphrase and Publickey authentication methods to
1106 config file, allowing both public key and passphrase based
1107 authentication to be set at the same time.
1109 Added `prefer_passphrase_auth' setting in config file which
1110 can be used to set to prefer passwd auth if both passwd and
1111 public key is set. If not set, public key is preferred.
1112 This has effect only when being initiator (responder will try
1115 Added support for authentication with passphrase and public key
1116 at the same time. The passphrase is tried first always since
1117 it is faster to check.
1119 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1121 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1123 * Merged the new SILC Config library, with the server parsing
1124 support. Read the header file silcconfig.h or the toolkit
1125 documentation for the news. Affected files are

1148 Payload. Affected file lib/silccore/silcchannel.c.
1150 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1151 as header filenames.
1153 * Removed lib/silcclient/README and created HTML file
1154 lib/silcclient/silcclient_using.html, which is now included
1155 as part of Toolkit documentation.
1157 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1159 * Fixed CUMODE_CHANGE notify handling to change the mode of
1160 correct client. Affected file lib/silcclient/client_notify.c.

1167 * Fixed the file transfer's key agreement payload to include
1168 zero port also if the hostname is NULL because it could not
1171 Call file transfer monitor callback now also if error occurs
1172 during key agreement protocol.
1174 Changed the silc_client_file_send interface to return the
1175 SilcClientFileError instead of session id. The session ID
1176 is returned into pointer provided as argument.
1178 Check that the file exists locally before sending the
1179 file transfer request at all.
1181 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1183 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1184 error than can occur while key agreement protocol. Affected
1185 file lib/silcclient/silcapi.h.

1191 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1192 SILC_LOG_WARNING to give out Warning and not Error. Affected
1193 file lib/silcutil/silclog.c.
1195 * Fixed the channel message payload decryption in the function
1196 silc_channel_message_payload_decrypt to not modify the original
1197 buffer before it is verified that the message decrypted
1198 correctly. Otherwise, next time it is called with correct
1199 channel key it won't encrypt since the payload is corrupted.
1200 Affected file lib/silccore/silcchannel.c.
1202 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1212 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1214 * Fixed a bug in hash table internal routine for traversing
1215 the table with foreach callback. The current entry may
1216 become invalid in the callback but it was referenced after
1217 the callback returned.
1219 Do not allow auto rehashing of hash table during the
1220 silc_hash_table_foreach operation, for same reasons as it is
1221 not allowed for SilcHashTableList. Affected files are
1222 lib/silcutil/silchashtable.[ch].
1224 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1226 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1227 Win32 DLL. extern's in header files are now declared with
1230 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1232 * Fixed private message handling. It used some old code that
1233 caused the client to crash. Affecte file is
1234 lib/silcclient/client_prvmsg.c.
1236 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1238 * Added function silc_client_add_channel,
1239 silc_client_replace_channel_id, and removed functions
1240 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1241 from client library.
1243 * Added cross reference of the joined channels to the
1244 SilcClientEntry, and changed the SilcChannelEntry's
1245 users list to SilcHashTable. The affected files are
1246 lib/silcclient/idlist.[ch].
1248 * Fixed a bug in hash table tarversing. While the hash table
1249 is traversed with SilcHashTableList the table must not be
1250 rehashed. It is now guaranteed that auto rehashable tables
1251 are not rehashed while tarversing the list. Also defined that
1252 silc_hash_table_rehash must not be called while tarversing
1253 the table. Added function silc_hash_table_list_reset that must
1254 be called after the tarversing is over. The affected files are
1255 lib/silcutil/silchashtable.[ch].
1257 * Changed all hash table traversing to call the new
1258 silc_hash_table_list_reset in server and in client library.
1260 * Added function silc_client_on_channel to return the
1261 SilcChannelUser entry if the specified client entry is joined
1262 on the specified channel. This is exported to application as
1263 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1265 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1267 * Fixed founder regaining problem with JOIN command on normal
1268 server. The notify for mode change must be sent always and
1269 not only if !cmd->pending. Affected file silcd/command.c.
1271 * Fixed the WHOWAS command's reply sending to support the
1272 lists correctly. Affected file silcd/command.c.
1274 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1276 * When sending JOIN command to router for processing the
1277 sender's old command identifier was not saved back to the
1278 sender's command context, fixed now. The affected file is
1281 * Create the key in JOIN command of the router did not return
1282 the channel key, added check for this. Affected file is
1285 * Fixed a channel ID update bug in JOIN command reply. Do
1286 not directly upgrade the ID but call the function
1287 silc_idlist_replace_channel_id if the ID was changed.
1288 Affected file silcd/command_reply.c.
1290 * Fixed memory leaks from command calling if it would fail.
1291 Affected file silcd/command.c.
1293 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1295 * Applied patches from cras:
1297 Memory leak fixes around libaries, irssi window resize fix,
1298 new silclist.h and silcdlist.h, all extern inline changed to
1301 * Removed dotconf from lib/dotconf, not needed anymore.
1303 * Removed TRQ from lib/trq, not needed anymore.
1305 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1306 with server connections. Later this will be configurable
1307 in config file after new config file is done. Affected file
1310 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1312 * Fixed a crash in server related to channel announcements.
1313 Affected file silcd/server.c.
1315 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1317 * Fixed memory leaks in silc_server_create_new_channel*
1318 functions. Affected file silcd/server.c.
1320 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1321 which ID was changed. This way the router will send the
1322 user list for the channel again, and server won't be in
1323 desync in some rare circumstances. Affected file is
1324 silcd/packet_receive.c.
1326 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1328 * Check for NULL socket pointer in the function
1329 silc_server_packet_send_to_channel_real. Affected file
1330 silcd/packet_send.c.

1337 * Fixed some header addition to Toolkit distribution in
1338 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1340 * Added lib/silcclient/client_ops_example.h as an template
1341 file for application programmers to quickly start using
1342 the SilcClientOperation functions in their application.
1343 Updated the lib/silcclient/README as well to tell about this
1344 nice file made available.
1346 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1348 * Call silc_server_remove_from_channels when removing client
1349 entry when NO_SUCH_CLIENT_ID was received. Affected file
1350 is silcd/command_reply.c.
1352 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1354 * Added server & router operator statistics updating. Affected
1355 file silcd/packet_receive.c and silcd/command.c.
1357 * Fixed the SERVER_SIGNOFF notify handling on normal server
1358 not to save the history information for clients. Same was
1359 fixed earlier in remove_clients_by_server function, but not
1360 here. Affected file silcd/packet_receive.c.
1362 * Raised the default connection-retry count from 4 to 7 in
1363 server. Affected file silcd/server.h.
1365 * Cancel any possible reconnect timeouts when we start the
1366 key exchange. Affected file silcd/server.c.
1368 * Do not reconnect on connection failure when SCONNECT was
1369 given. Affected files silcd/server.[ch].
1371 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1373 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1375 * Fixed the NICK command to always give the unformatted
1376 nickname to the one giving the NICK command. If unformatted
1377 nickname is cached already it will be formatted and the
1378 local entry will always get the unformatted nickname.
1379 Affected file lib/silcclient/idlist.c.
1381 * Fixed some double frees from client library commands.
1382 Affected file is lib/silcclient/command.c.
1384 * Fixed CUMODE command in server to assure that no one can
1385 change founder's mode than the founder itself, there was a
1386 little bug. Affected file silcd/command.c.
1388 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1390 * Removed the SilcClientCommandDestructor from the client
1391 libary, it is not needed anymore. Affected files are
1392 lib/silcclient/silcapi.h, command[_reply].[ch],
1393 client_notify, idlist.c.
1395 * Fixed GETKEY command to first resolve client, and then
1396 resolve the server only if the client was not found, instead
1397 of resolving both at the same time. Affected file is
1398 lib/silcclient/command.c.
1400 * Added silc_client_start_key_exchange_cb and lookup the
1401 remote hostname and IP address before starting the key
1402 exchange with server. The affected file is
1403 lib/silcclient/client.c.
1405 * The server's public key is now saved using the IP address
1406 of the server and not the servername for the filename.
1407 The hostname public key filename is checked as an fall back
1408 method if the IP address based filename is not found.
1410 Fixed the GETKEY command to save the fetched server key
1411 in correct filename.
1413 Print the remote server's hostname now when new key is
1414 received during connection process. Affected file is
1415 irssi/src/silc/core/client_ops.c.
1417 * Return always our own public key to the client if it asks
1418 for it with GETKEY command. Affected file silcd/command.c.
1420 * Removed the use_auto_addr variable from default config
1421 file since it was in wrong section. Affected file is
1424 * Fixed TOPIC_CHANGE notification to not route it when it
1425 was sent using silc_server_send_notify_to_channel function.
1426 Affected file silcd/command.c.
1428 * Fixed silc_server_send_notify_kicked to send the kicker's
1429 Client ID also, it was missing. Affected files are
1430 silcd/command.c, silcd/packet_send.[ch].
1432 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1434 * Do not save client history information in SERVER_SIGNOFF.
1435 Fixes the bug in normal server that it does not detect
1436 the client becoming valid after the server becomes back
1437 online. Affected file silcd/server_util.c.
1439 * Added `sock_error' field into the SilcSocketConnection
1440 context. When error occurs during socket operation (read
1441 or write) the error is saved. Added also new function
1442 silc_socket_get_error to return human readable socket error
1443 message. Affected files are lib/silcutil/silcsockconn.[ch],
1444 lib/silcutil/unix/silcunixsockconn.c, and
1445 lib/silcutil/win32/silcwin32sockconn.c.
1447 * The server now prints the socket error message in the
1448 signoff for client. Affected file silcd/server.c.
1450 * Fixed the `created' channel information sending from router
1451 to server in JOIN command. Checks now whether the channel
1452 really was created or not and set it according that.
1454 Fixed the JOIN command to use the client entry's current
1455 ID during the joining procedure instead of the one it sent
1456 in the command (it is checked though), since it can change
1457 between the packet processing and command processing, and
1458 would just case unnecessary pain in the client end. Affected
1459 file silcd/command.c.
1461 * Fixed a channel key payload sending to use correct channel
1462 ID when the server was forced to change the channel's ID by
1463 router. Router sent the key payload with the old Channel ID.
1464 Affected file silcd/packet_receive.c.
1466 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1468 * Call silc_server_save_channel_key only if the key payload
1469 was provided in the JOIN command's command reply. Affected
1470 file silcd/command_reply.c.
1472 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1474 * Fixed silc_mp_sizeinbase to return the value correctly with
1475 MPI. Affected file lib/silcmath/mp_mpi.c.
1477 * Fixed the stop_server signal to correctly stop the scheduler
1478 and gracefully stop the server when SIGTERM or SIGINT signals
1479 are received. Affected file silcd/silcd.c.
1481 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1483 * Simple handling of TERM and HUP signals. Also added some log
1484 flushing call around. Affected file is
1487 * Fixed small bugs in silclog.c. Now buffering output will take
1488 effect after 10 seconds since startup: This will ensure that
1489 no important startup messages are lost. Also output redirection
1490 will preserve original format ([Date] [Type] message).
1491 Affected file is lib/silcutil/silclog.c.
1493 * Added two options to the config file, in the logging section:
1494 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1495 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1497 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1499 * Do not print the warning about log files not being initialized
1500 more than once to avoid excess logging. Affected file is
1501 lib/silcutil/silclog.c.
1503 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1504 the SIM copying in make install in Makefile.am.pre.
1506 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1508 * Rewritten silclog APIs. Globally interesting changes follows:
1509 silc_log_set_files() changed to silc_log_set_file().
1510 silc_log_set_callbacks() changed to silc_log_set_callback().
1511 ROBOdoc documented silclog header file.
1512 SilcLogCb now returns bool to wether inihibit the default
1513 handler or not (to keep the old behaviour return always TRUE).
1514 The new APIs should also fix the problem of the
1515 silcd_error.log file that was written in the current directory.
1518 Log files streams will remain opened after silc_log_set_file()
1519 call, means less CPU usage notably on high traffic servers.
1520 File streams are now full buffered, and flushed to the disk
1521 every 5 minutes, lesses HD activity and CPU usage.
1522 Messages can be redirected, allowing admins to configure
1523 one single logfile for all server messages.
1524 the silc_log_quick global variable to activate fast-logging.
1525 Affected files lib/silcutil/silclog.[ch]
1527 * Changed some code to conform new silclog APIs. Affected
1528 files are doc/example_silcd.conf.in, silcd/server.c
1529 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1532 * Fixed a memory leak that could occur in some situations.
1533 Affected file silcd/serverconfig.c.
1535 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1537 * Added the silc_client_del_client to remove the client from
1538 all channels as well. Affected file lib/silcclient/idlist.c.
1540 * Fixed the client library to correctly remove the client
1541 from all channels when the client entry is being destroyed.
1542 Affected file lib/silcclient/client_notify.c, command.c.
1544 * Added auto-nicking support to the client library. If the
1545 applicatio now sets client->nickname it will be sent to the
1546 server after connecting by the library. This way for example
1547 SILCNICK (or IRCNICK) environment variables will have effect
1548 and always change the nickname automatically to whatever
1549 it is wanted. Affected file lib/silcclient/client.[ch].
1551 * Renamed silc_server_command_bad_chars to the
1552 silc_server_name_bad_chars and moved it to the
1553 silcd/server_util.[ch]. Added also new function
1554 silc_server_name_modify_bad to return nickname that
1555 includes bad characters as new nickname without those
1556 bad characters. This check and modify is now used in
1557 silc_server_new_client when the username is initially set
1558 as nickname, so it must be checked to be valid nickname.
1559 Affected file silcd/packet_receive.c.
1561 * The nickname length is now taken from the packet for real
1562 and not trusted to strlen() since it clearly can return
1563 wrong length for nickname including bad characters. This
1564 also applies to channel names. Affected file silcd/command.c.
1566 * Removed the lib/silcsilm/modules directory. Modules are now
1567 compiled into the lib/silcsim. Fixed the copying of the
1568 modules to follow symbolic links in Makefile.am.pre.
1570 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1572 * Fixed silc_string_regexify list creation. Fixes bugs with
1573 BAN and INVITE commands in server. The affected file is
1574 lib/silcutil/unix/silcunixutil.c.
1576 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1578 * Removed the command destructor entirely from the server's
1579 command and command reply routines. It is not needed, and
1580 its usage was buggy and caused crashes. Affected files are
1581 silcd/command[_reply].[ch].
1583 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1585 * Cancel protocol and NULL sock->protocol if timeout
1586 occurred during protocol. Affected file silcd/server.c.
1588 * Cancel protocol timeouts always before calling the final
1589 callback, to assure that after final callback is called
1590 no other state will be called for the protocol anymore.
1591 Affected file silcd/protocol.c.
1593 * Print error log if incoming connection configuration could
1594 not be found. Affected file silcd/server.c.
1596 * Fixed JOIN command to correctly save the founder mode
1597 to the client on normal SILC server, when the channel
1598 was created by the router. Affected file silcd/command.c.
1600 * Fixed LIST command (hopefully) to send correct reply
1601 packets. Affected file silcd/command.c.
1603 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1605 * The silc_packet_receive_process now returns FALSE if the
1606 read data was invalid packet, and TRUE if it was ok.
1608 The server now checks that if unauthenticated connection
1609 sends data and its processing fails the server will close
1610 the connection since it could be a malicious flooder.
1612 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1614 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1616 * Make sure the warning about error opening a log file is
1617 printed only once and not everytime it fails (produces
1618 too much useless log). Affected file lib/silcutil/silclog.c.
1620 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1622 * Made the silc_server_daemonise() function more readable.
1623 Affected file silcd/server.c.
1625 * Pid file is now optional, the user may comment it out from
1626 the config file. Removed define SILC_SERVER_PID_FILE, we
1627 don't need a default any longer. Affected file
1628 configure.in.pre, lib/Makefile.am.pre.
1630 * Make some use of the pid file. The server now dies at startup
1631 if it detects a valid pid file on his path. The server would
1632 die anyway in this circumstance, because of the bind() failure.
1633 Affected file silcd/silcd.c.
1635 * No longer compiling lib/dotconf.
1637 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1639 * Fixed JOIN command parsing not to crash. Affected file
1640 lib/silcclient/command.c.
1642 * Fied the NICK_CHANGE notify to add the new client entry
1643 even it is resolved. This removes an <[unknown]> nick
1644 thingy bug in the client. Affected file is
1645 lib/silcclient/client_notify.c.
1647 * Do not try to allocate 0 bytes (efence does not like it)
1648 in lib/silccore/silccomand.c when encoding payload.
1650 * Do not take IRCNICK as nickname in Irssi SILC client since
1651 it is not possible to set nickname before hand connecting
1652 the server (TODO has an entry about adding auto-nicking
1655 * Changed the silc_server_command_pending to check whether
1656 there already exists an pending entry with the specified
1657 command, command identifier and pending callback. This is
1658 to fix IDENTIFY and WHOIS related crashes that may register
1659 multiple pending commands with same identifier. Affected
1660 file silcd/command.c.
1662 * Fixed the server to reconnect to the router even if it
1663 was already reconnecting and EOF was received. This to
1664 fix a possibility that the server wouldn't ever try to
1665 auto-reconnect to the router. Affected file silcd/server.c.
1667 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1669 * Fixed the server's password authentication to use the
1670 length of the locally saved password, and not the one
1671 sent in the packet. Affected file silcd/protocol.c.
1673 * Fixed same password authentication problem in the
1674 Authentication Payload handling routines in
1675 lib/silccore/silcauth.c.
1677 * Yet another password authentication problem fixed with
1678 channel password handling in silcd/command.c.
1680 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * If first character of string in silc_parse_userfqdn is '@'
1683 then do not parse it. Affected file is
1684 lib/silcutil/silcutil.c.
1686 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Fixed minor bug in IDENTIFY command reply sending, which
1689 caused various weird problems during JOIN when it was
1690 resolving names for users. Affected file silcd/command.c.
1692 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * Fixed the IDENTIFY command reply sending to chech better valid
1695 clients. It was possible to send incomplete list of replies.
1696 Affected file silcd/command.c.
1698 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1700 * Added silc_client_command[s]_[un]register functions now to
1701 dynamically register the commands in client library. Removed
1702 the static table of commands. This allows the client library
1703 to call commands without causing the application to know about
1704 what commands library has called.
1706 Removed the INFO command reply kludge to detect when the command
1707 was called by library. Now library use its own command reply
1708 function for INFO command.
1710 Added function silc_client_command_call to call a command.
1711 Application can use it to call command, not access the structure
1714 Now all commands that are sent by the client library (not
1715 explicitly sent by application) use own command reply functions.
1717 Affected files around lib/silcclient/ and in
1718 irssi/src/silc/core/.
1720 * Fixed the WHOIS command reply sending to chech better valid
1721 clients. It was possible to send incomplete list of replies.
1723 Fixed the WHOIS and IDENTIFY to send the request to router
1724 if normal server did not do it and did not find any results.
1726 Affected file silcd/command.c.
1728 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1730 * Moved the internal data from SilcClient context into its
1731 own file, not accesible to application. Affected files
1732 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1733 and other files in client library.
1735 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * Added doc/examples installation target in Makefile.am.pre.
1740 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1743 commands the found client entry will be removed from the
1744 cache, after notifying application about the error. Affected
1745 file lib/silcclient/command_reply.c.
1747 * Changed the /MSG to check for exact nickname user gave, and
1748 not let `nick' match `nick@host' if it is only one found. Now,
1749 user must type the exact nickname (like nick@host2) even if
1750 there are no more than one same nicks found. This is to avoid
1751 a possibility of sending nickname to wrong nickname since
1752 `nick' could match `nick@host'. Affected file is
1753 irssi/src/core/silc-servers.c.
1755 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1757 * Do not print "you are now server operator" or similar when
1758 giving /away command. Affected files are
1759 irssi/src/silc/core/client_ops.c, silc-servers.h.
1761 * Made the silc_server_command_pending_error_check to send
1762 the same command reply payload it received back to the
1763 original sender of the command. This way all arguments
1764 that was received by the server will be received by the
1765 client too. Affected file silcd/command.c.
1767 * Added the silc_idcache_add to return the created cache entry
1768 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1770 * Add global clients to expire if they are not on any channel.
1771 This is because normal server will never know if they signoff
1772 if they are not on any channel. The cache expiry will take
1773 case of these entries. This is done by normal servers only.
1774 The affected files are silcd/command_reply.c,
1775 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1777 * If server receives invalid ID notification for WHOIS or
1778 IDENTIFY and the ID exists in the lists, it is removed.
1779 Affected file silcd/command_reply.c.
1781 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1782 in client then client entry that it matches is searched and
1783 the nickname is printed on the screen for user. Affected
1784 file irssi/src/silc/core/client_ops.c.
1786 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1788 * Use cache entry expire time in the LIST command reply to
1789 purge old entries from the cache after the LIST command
1790 reply has been received. This way we don't have non-existent
1791 entries in the cache for too long. Affected file is
1792 silcd/command_reply.c.
1794 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1796 * If we are normal server, and we've not resolved client info
1797 in WHOIS or IDENTIFY from router, and it is global client,
1798 we'll check whether it is on some channel. If it is not
1799 then we cannot be sure about its validity and will resolve it
1800 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1801 file silcd/command.c.
1803 * Search channel by name (if possible) rather than by ID
1804 in IDENTIFY command's command reply. Affected file is
1805 silcd/command_reply.c.
1807 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1809 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1810 Updated specs and implemented it. Affected file silcd/command.c,
1811 silcd/packet_send.c and silcd/packet_receive.c.
1813 * Implemented the <founder auth> payload handling in the JOIN
1814 command. If provided all conditions for channel joining
1815 except requirement to provide correct passphrase can be
1816 overrided by the channel founder. Updated the protocol specs.
1817 Affected file silcd/command.c.
1819 Added support for founder auth in JOIN command in client
1820 library. Fixed the parsing of the JOIN command now to support
1821 all options as they should be. The affected file is
1822 lib/silcclient/command.c.
1824 * Optimized the WHOIS and IDENTIFY commands to send the request
1825 to router only if it includes nicknames or other names. If
1826 they include only IDs then check the local cache first before
1827 routing. Affected file is silcd/command.c.
1829 * Added channels topic announcements. Affected file is
1830 silcd/packet_receive.c and silcd/server.c.
1832 * Fixed the silc_server_send_notify_topic_set to really destine
1833 the packet to channel. Affected file silcd/packet_send.c.
1835 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1836 library. Affected file lib/silcclient/client_notify.c.
1838 * Added UMODE announcements. Affected file silcd/server.c.
1840 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * Memory leak fixes in:
1844 lib/silcutil/silcsockconn.c
1845 lib/silcske/silcske.c
1846 lib/silcske/groups.c
1848 lib/silccrypt/silcpkcs.c
1849 lib/silccore/silccommand.c
1850 lib/silccore/silcidcache.c
1855 * ROBOdoc documented the lib/silcske/groups.h file and a
1856 bit changed the interface for better.
1858 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1860 * Update the client entry context in the ID cache after
1861 nick change. Affected file lib/silcclient/command.c.
1862 Fixes the CUMODE command when regaining founder privileges,
1863 and a little WHOIS problem.
1865 * Fixed silc_net_gethostbyname to correctly call the
1866 inet_ntop. Affected file lib/silcutil/silcnet.c.
1868 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1870 * Added IPv6 support checking to the configure.in.pre, added
1871 also --enable-ipv6 option to override the check. Affected
1872 file configure.in.pre.
1874 * The silc_thread_create now calls the start function
1875 directly if threads support is not compiled in. Removes
1876 ugly #ifdef's from generic code. Affected files are
1877 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1879 * Added silc_net_gethostby[name/addr]_async to asynchronously
1880 resolve. Affected files are lib/silcutil/silcnet.[ch].
1882 * Added support for rendering IPv6 based server, client and
1883 channel IDs. Affected file lib/silcutil/silcutil.c.
1885 * Added support for creating IPv6 based server IDs. Affected
1886 file is silcd/serverid.c.
1888 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1890 * Added silc_net_gethostby[addr/name] into the
1891 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1892 routines. Added silc_net_is_ip[4/6]. Affected file is
1893 lib/silcutil/unix/silcunixnet.c. All routines that take
1894 address as argument now supports both IPv4 and IPv6 addresses.
1896 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1898 * Fixed LIST command reply sending in server. Affected file
1901 * Server now sends the kicker's client ID in the KICK notify
1902 to the kicked client. Affected file silcd/command.c.
1904 * The client library now parses the kickers client ID and
1905 UI displays it. Affected files lib/silcclient/client_notify.c
1906 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1908 * Made all payload parsing function prototypes consistent.
1909 They all take now const unsigned char * and uint32 pair as
1910 the payload data instead of SilcBuffer. Changes all around
1911 the source tree. Other unsigned char* -> const unsigned char*
1912 changes around the tree as well.
1914 * Optimized SFTP client and server packet sending not to
1915 allocate new buffer for each packet but to recycle the
1916 first allocated buffer. Affected files are
1917 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1919 * Optimized the SFTP client to use SilcList instead of
1920 SilcDList for requests, because it is faster. Affected file
1921 is lib/silcsftp/sftp_client.c.
1923 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1924 into lib/silccore/silcid.[ch].
1926 Renamed silcpayload.[ch] into silcargument.[ch].
1928 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1930 * If client entry is deleted with active key agreement
1931 session, abort the session.
1933 The silc_client_abort_key_agreement now calls the completion
1934 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1936 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1939 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1941 * Don't use __restrict in older GCC's. Affected file is
1942 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1944 * silc_net_localhost now attempts to reverse lookup the
1945 IP/hostname. Affected file lib/silcutil/silcnet.c.
1947 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1948 command. It can be used to gain founder privileges at
1949 the same time when joining the channel.
1951 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1952 kicker's client ID as well. Updated protocol specs.
1954 Defined that the server must send SILC_COMMAND_IDENTIFY
1955 command reply with error status to client who sent
1956 private message with invalid client ID.
1958 Updated the protocol specification.
1960 * Added silc_server_send_command_reply to send any
1961 command reply. Affected file silcd/packet_send.[ch].
1963 * Added silc_id_payload_encode_data to encode ID payload
1964 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1966 * The server now send IDENTIFY command reply with error
1967 status if client ID in private message is invalid. Affected
1968 file silcd/packet_receive.c.
1970 * Save the server key file with server's IP address in
1971 the filename instead of hostname. The affected file is
1972 irssi/src/silc/core/client_ops.c.
1974 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1976 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1979 * Added libtool support for compiling shared objects in
1980 lib/silcsim. Affected file configure.in.pre and
1981 lib/silcsim/Makefile.am. Original patch by cras.
1983 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Pid file configuration, and server's config file fixes
1986 patch by toma. Updated CREDITS file.
1988 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Fixed silc_client_channel_message to not try to decrypt
1991 the message twice if it resolved the destination client
1992 information. This could cause of dropping one channel
1993 message. Affected file lib/silcclient/client_channel.c.
1995 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1998 lib/silcclient/client.c. This function is used when the SILC
1999 Client is run under some other scheduler, or event loop or
2000 main loop. On GUI applications, for example this may be
2001 desired to used to run the client under the GUI application's
2002 main loop. Typically the GUI application would register an
2003 idle task that calls this function multiple times in a second
2004 to quickly process the SILC specific data.
2006 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2008 * Fixed silc_server_drop() for dropping the supplementary
2009 groups as well, this could cause a security hole on some
2012 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2014 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

2018 to run server on foreground. A patch by debolaz.
2019 Affected files silcd/server.c, silcd/silcd.c.
2021 * Fixed MOTD to return the MOTD file server name. Affected
2022 file silcd/command.c.
2024 * Added INFO command reply handling to the Irssi SILC Client.
2025 Affected file irssi/src/silc/core/client_ops.c.
2027 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2029 * Fixed the silc_idcache_list_* routines to really support
2030 the dynamic list. Fixes a crash. Affected file is
2031 lib/silccore/silcidcache.c.
2033 * Fixed the LIST command reply to really call LIST command's
2034 pending callbacks. Affected file silcd/command_reply.c.
2036 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2038 * Update conn->local_entry->nickname after giving NICK
2039 command. Affected file lib/silcclient/command.c.
2041 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2043 * Added the [pid] option to the silcd configuration file
2045 Affected files: serverconfig.[ch] and silcd.c
2047 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * Save fingerprint in WHOIS command reply in server.
2050 Affected file silcd/command_reply.c.
2052 * Fixed NICK commands pending callback registration.
2053 Affected file lib/silcclient/command.c.
2055 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2057 * Use ++server->cmd_ident when sending commands in server,
2058 instead of random number. Affected file silcd/command.c.
2060 * Fixed GETKEY command reply to call actually GETKEY pending
2061 command callbacks. Affected file silcd/command_reply.c.
2063 * A bit stricter check for nicknames. Check for same nickname
2064 in NICK command also. Affected file silcd/command.c.
2066 * Do not call INFO command everytime client ID changes, only
2067 during first connecting. Affected file lib/silcclient/client.c.
2069 * Set the new nickname only after successful command reply for
2070 NICK command is returned by server. Affected file
2071 lib/silcclient/command.c.
2073 * Remove nicknames from nicklist during server_signoff notify.
2074 Should fix /NAMES bit more. The affected file is
2075 irssi/src/silc/core/silc-channels.c.
2077 * Added `fingerprint' field to the SilcIDListData in the
2078 silcd/idlist.h to hold the fingerprint of the client's
2081 Send the fingerprint of the client's public key in WHOIS
2084 Affected files silcd/command.c, and silcd/idlist.[ch].
2086 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2087 create fingerprint from given data.
2089 * Show the fingerprint of the client's public key in WHOIS.
2090 Affected files irssi/src/module-formats.[ch] and
2091 irssi/src/silc/core/client_ops.c.
2093 * Format the multiple same nicknames also during JOIN and
2094 NICK_CHANGE notifys. Affected file is
2095 lib/silcclient/client_notify.c.
2097 * Do not print error on screen for invalid private message
2098 payload since it can come if someone is sending private
2099 messages with wrong key. Affected file
2100 lib/silccore/silcprivate.c.
2102 * Fixed multiple concurrent /PING crash. Affected file
2103 lib/silcclient/command.c.
2105 * Changed the wrong ID encoding. All IP addresses must be
2106 in MSB first order in encoded format. They were encoded
2107 wrong and was in LSB format. Affected files are
2108 silcd/serverid.c, lib/silcutil/silcutil.c.
2110 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2112 * Call the `connect' client operation through the scheduler
2113 in case of error. Affected file lib/silcclient/client.c.
2115 * Call the `failure' client operation even if the error
2116 occurred locally during a protocol. Affected file is
2117 lib/silcclient/protocol.c.
2119 * Added support of sending LIST command to router from normal
2120 server. This way normal server can get list of all channels
2121 in the network too. Fixed the channel list sending in the
2122 server too. Affected files are silcd/command.c, and
2123 silcd/command_reply.[ch].
2125 * Added silc_server_update_channels_by_server and
2126 silc_server_remove_channels_by_server. They are used during
2127 disconnection of primary router and in backup router protocol.
2128 Affected file silcd/server_util.[ch], silcd/server.c and
2129 silcd/server_backup.c.
2131 * Fixed channel adding to global list in IDENTIFY command
2132 reply in server. Affected file silcd/command_reply.c.
2134 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2136 * If the incoming packet type is REKEY or REKEY_DONE process
2137 that packet always synchronously. Fixes yet another MAC
2138 failed error on slow (dialup) connections. Affected file
2139 lib/silcclient/client.c and silcd/server.c.
2141 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Call check_version SKE callback for initiator too. Affected
2144 file lib/silcske/silcske.c.
2146 * Implemented fix for security hole found in the SKE that was
2147 fixed in the specification few days back; the initiator's
2148 public key is now added to the HASH value computation.
2149 Added backwards support for the old way of doing it too, for
2150 old clients and old servers. Affected file is
2151 lib/silcske/silcske.c.
2153 * Enabled mutual authentication by default in SKE. If initiator
2154 is not providing mutual authentication the responder will
2155 force it. This will provide the proof of posession of the
2156 private key for responder. The affected files are
2157 lib/silcclient/protocol.c and silcd/protocol.c.
2159 * Do not cache anymore the server's public key during SKE.
2160 We do mutual authentication so the proof of posession of
2161 private key is done, and if the server is authenticated in
2162 conn auth protocol with public key we must have the public
2163 key already. Affected file silcd/protocol.c.
2165 * Added new global debug variable: silc_debug_hexdump. If
2166 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2167 file lib/silcutil/silclog.[ch].
2169 * Fixed compilation warning due to char * -> const char *.
2170 Affected files lib/silcutil/silcnet.h, and
2171 lib/silccore/silcauth.[ch].
2173 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * Fixed CMODE command when new channel key was created. If
2176 the creation failed the old key was removed. Next time giving
2177 same command would crash the server since the old key was
2178 freed already. Affected file silcd/command.c.
2180 * Fixed the silc_server_announce_get_channels to not crash
2181 on reconnect. Affected file silcd/server.c.
2183 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2185 * Added silc_log_set_debug_string function to set a regex
2186 string to match for debug output. Only the function names,
2187 or filenames matching the given debug string is actually
2188 printed. This way it is possible to filter out those debug
2189 strings that user is not interested in.
2191 Fixed a bug in silc_string_regexify.
2193 Affected files lib/silcutil/silclog.[ch], and
2194 lib/silcutil/unix/silcunixutil.c.
2196 * Changed the -d options in both server and Irssi SILC client
2197 to take the debug string as argument. Affected files
2198 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2200 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2202 * Added silc_hash_babbleprint to create a Bubble Babble
2203 Encoded fingerprint. The encoding is developed by Antti
2204 Huima (draft-huima-babble-01.txt), and it creates human
2205 readable strings out of binary data. Affected file
2206 lib/silccrypt/silchash.[ch].
2208 * Print the babble print now in addition of fingerprint as well
2209 in Irssi SILC client. Affected files are
2210 irssi/src/fe-common/silc/module-formats.[ch],
2211 irssi/src/fe-common/silc/core/client_ops.c.
2213 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2215 * Fixed a security problem found in SKE. The initiator's
2216 public key too is now added to the HASH hash value creation
2217 which is signed by the responder to create the SIGN value.
2218 This will prevent anyone in the middle to lie to the responder
2219 about the initiator's public key. If this is done now, the
2220 man in the middle will get caught. Updated the protocol
2223 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * Better installation directory handling. Configure module
2226 paths and other paths automatically to example_silc* files
2227 in doc/. A patch by toma.
2229 * Fixed compiler warning from MPI library, and from SILC RNG.
2232 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2233 It can be configured with ./configure. A patch by toma.
2235 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * Find correct make to use in prepare-clean. A patch by
2238 toma. Affected file prepare-clean.
2240 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2242 * Added irssi variables use_auto_addr, auto_bind_ip,
2243 auto_bind_port and auto_public_ip.
2245 * Changed the interface for silc_client_send_key_agreement
2246 in lib/silcclient/silcapi.h
2250 irssi/src/silc/core/silc-core.c
2252 lib/silcclient/silcapi.h
2253 irssi/src/silc/core/silc-channels.c
2254 lib/silcclient/client_keyagr.c
2257 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2259 * Added silc_pkcs_public_key_compare to compare two
2260 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2262 * Check that the client who set the founder mode on the
2263 channel is the same client that is giving the founder
2264 mode to itself. It is done by comparing the saved public
2265 key (it is saved even in the authentication is passphrase).
2266 Affected file silcd/command.c.
2268 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2270 * Do not process packet for disconnected socket connection.
2271 Affected file lib/silccore/silcpacket.c.
2273 * Process the DISCONNECT packet through scheduler in the
2274 client library. Affected file lib/silcclient/client.c.
2276 * Fixed the silc_client_packet_parse to not to increase
2277 the packet sequence number if the conn->sock and the
2278 current socket connection is not same. This can happen
2279 for example during key agreement when the conn includes
2280 multiple socket connections (listeners). Affected file
2281 lib/silcclient/client.c.
2283 * The sender of the file transfer request now provides also
2284 the pointer (listener) for the key exchange protocol. If
2285 the listener cannot be created then it sends empty key
2286 agreement and lets the receiver provide the listener.
2288 Added `local_ip' and `local_port' arguments to the
2289 silc_client_file_send. If they are provided they are used,
2290 if not then it will attempt to find local IP address, if
2291 not found or bind fails then the remote client will provide
2294 Affected files are lib/silcclient/client_ftp.c and
2295 lib/silcclient/silcapi.h.
2297 * Extended the FILE SEND command to support defining the
2298 local IP and port for key exchange listener. They are
2299 optional. Affected file irssi/src/silc/core/silc-servers.c.
2301 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Defined to WHOIS command reply the sending of fingerprint
2304 of the client's public key (if the proof of posession of the
2305 corresponding private key is verified by the server).
2306 Updated to the protocol specification.
2308 * Added support of receiving the client's public key's
2309 fingerprint in command reply in client library. Affected
2310 file is lib/silcclient/command_reply.c, and
2311 lib/silcclient/idlist.[ch].
2313 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2315 * Do not send over 128 chars long nickname to the server
2316 in NICK command. Affected file lib/silcclient/command.c.
2318 * Do not send over 256 chars long channel names to the server
2319 in JOIN command. Affected file lib/silcclient/command.c.
2321 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Assure that silc_server_close_connection cannot be called
2324 twice for same socket context. Affected file is
2327 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2329 * Send error message to application if opening file for
2330 writing during file transfer fails. Affected file is
2331 lib/silcclient/client_ftp.c.
2333 Remove all file transfer sessions for a client that we're
2334 removing from ID cache.
2336 Affected file is lib/silcclient/client_ftp.c.
2338 * Fixed silc_net_addr2bin to return correct address. Affected
2339 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2341 * Fixed file transfer session removing on signoff notify.
2342 Affected file irssi/src/silc/core/silc-servers.c.
2344 * Added the SilcClientFileError to be returned in the monitor
2345 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2346 Affected file lib/silcclient/silcapi.h.
2348 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2350 * Fixed a crash in silc_client_ftp_free_sessions and
2351 silc_client_ftp_session_free_client. Affected file
2352 lib/silcclient/client_ftp.c.
2354 * Added `disabled' field in the SilcChannelEntry in the server
2355 to indicate if the server entry is disabled. Affected file
2356 silcd/idlist.h, silcd/command[_reply].c.
2358 * SILC server adds now /var/run/silcd.pid everytime it is
2359 started. Affected file silcd/silcd.c.
2361 * Added silc_server_packet_send_clients to send a packet to
2362 the provided table of client entries. Affected file
2363 silcd/packet_send.[ch].
2365 * Fixed a crash in client resolving in client_prvmsg.c in
2366 client library. Affected file lib/silcclient/client_prvmsg.c.
2368 * Do not actually remove the client directly from ID cache
2369 during SERVER_SIGNOFF, but invalidate it. This way we
2370 preserve the WHOWAS info for the client. Affected file
2371 silcd/server_util.c.
2373 * Fixed SERVER_SIGNOFF notify handling in the server. The
2374 server is now able to process incoming SERVER_SIGNOFF notify
2375 for a server that it doesn't even know about. It will remove
2376 the clients provided in the notify. Affected file
2377 silcd/packet_receive.c.
2379 * Check for partial packet in data queue after every packet that
2380 was found from the queue. Return and wait for more data if
2381 there is partial data in queue. Affected file is
2382 lib/silccore/silcpacket.c.
2384 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2386 * Added SilcClietFileError enum to indicate error in
2387 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2388 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2389 Affected files lib/silcclient/silcapi.h and
2390 lib/silcclient/client_ftp.c.
2392 * Check that newsize in silc_buffer_realloc is larger than
2393 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2395 * Added better monitor of file transfers. It now monitors
2396 key agreement protocol during the file transfer too. Added
2397 error reporting too. Affected files
2398 irssi/src/silc/core/silc-servers.c,
2399 irssi/src/fe-common/silc/module-formats.[ch].
2401 * Wrote a help file for FILE command.
2403 * Added silc_rng_global_get_byte_fast to get not-so-secure
2404 random data as fast as possible. Random data is read from
2405 /dev/urandom if available and from the SILC RNG if not
2406 available. It is used in padding generation. Affected file
2407 lib/silccrypt/silcrng.[ch].
2409 * All packets in client library are now processed synchronously.
2410 Optimized packet processing a lot. Affected file
2411 lib/silcclient/client.c.
2413 * All server connection packets are processing synchronously
2414 now in server, to optimize packet processing. Affected file
2417 * Include files are installed now only in Toolkit distribution
2418 if make install is given. Affected files: all Makefile.am's.
2420 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2422 * Assure that silc_client_notify_by_server_resolve does not
2423 resolve the client information multiple times. If it cannot
2424 be found by the first it cannot be found at all. Affected
2425 file lib/silcclient/client_notify.c.
2427 * Fixed WHOWAS command reply calling. Affected file
2428 lib/silcclient/command_reply.c.
2430 * Removed all references to silc_idlist_get_client from the
2431 Irssi SILC client since that call is internal call used by
2432 the library. The Irssi SILC client will use now client
2433 retrieval functions found in silcapi.h.
2435 * Fixed a bug in resolving nickname info before sending
2436 private message. It used freed memory. Affected file
2437 irssi/src/silc/core/silc-servers.c.
2439 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Assure my_channels statistics cannot go negative in server.
2442 Affected files silcd/server.c, silcd/server_util.c.
2444 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2448 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2450 * Win32 Toolkit changes. Affected files
2451 win32/silc.dsw, win32/libsilc/libsilc.def,
2452 win32/libsilcclient/libsilc.def,
2453 lib/silcutil/silcutil.c, and
2454 lib/sftp/sftp_fs_memory.c.
2456 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2458 * Added silc_net_localip to return local host's IP address.
2459 Affected file lib/silcutil/silcnet.[ch].
2461 * If key exchange or rekey protocol is active for a connection
2462 parse all packets syncronously since there might be packets
2463 in packet queue that we are not able to process without first
2464 processing packets before them. Affected file silcd/server,
2465 lib/silcclient/client.c.
2467 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2468 whether library should continue processing the packet.
2469 Affected file lib/silccore/silcpacket.h.
2471 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2472 SilcSFTPMonitorData to SFTP server to monitor various
2473 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2474 lib/silcsftp/sftp_server.c.
2476 * Added silc_file_size to return file size. Affected file
2477 lib/silcutil/silcutil.[ch].
2479 * Implemented the file transfer support for the client library.
2480 Added preliminary support for simple client to client one-file
2481 transmission. Affected file lib/silcclient/client_ftp.c,
2482 lib/silccilent/client.[ch].
2484 * Added new local command FILE to the Irssi SILC Client.
2485 It is used to perform the file transfer. It has subcommands
2486 SEND, RECEIVE, SHOW and CLOSE. Affected files
2487 irssi/src/silc/core/client_ops.c,
2488 irssi/src/silc/core/silc-server.[ch].

2497 * Renamed silc_file_read and silc_file_write to functions
2498 silc_file_readfile and silc_file_writefile. Added function
2499 silc_file_open and silc_file_close. Affected files
2500 lib/silcutil/silcutil.[ch].
2502 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Resolve the client info when received private message or
2505 channel message for a client which nickname we don't know.
2506 Affected files lib/silcclient/client_prvmsg.c and
2507 lib/silcclient/client_channel.c.
2509 * Do not crash in /KEY if client is not connected. Affected
2510 file irssi/src/silc/core/silc-channels.c.
2512 * Added SilcClientStatus field to the SilcClientEntry in the
2513 lib/silcclient/idlist.h.
2515 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2516 is incomplete and is being resolved, it won't be resolved
2519 Make sure also that USERS command reply does not resolve
2520 twice information. Affected file is
2521 lib/silcclient/command_reply.c.
2523 Make sure that silc_client_get_clients_by_list does not
2524 resolve twice same information.
2526 * Check for valid client->id in the silc_server_free_client_data.
2527 Affected file silcd/server.c.
2529 * Fixed /GETKEY nick@server not to crash if the server entry
2530 is not found. Affected file lib/silcclient/command.c.
2532 * Fixed the silc_server_check_cmode_rights to check the
2533 requested modes correctly. Affected file silcd/command.c.
2535 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * Better checks for non-printable chars in nick added.
2538 Affected file silcd/command.c.
2540 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2542 * Call the silc_server_udpate_servers_by_server in the
2543 primary router that comes back online in the backup resuming
2544 protocol. Otherwise it routes packets wrong. Affected file
2545 silcd/server_util.[ch], silcd/server_backup.c.
2547 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2549 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2550 lib/silcutil/silcbuffmt.[ch].
2552 * Redefined the SILC packet header to include the padding
2553 length. Affected file lib/silccore/silcpacket.[ch].
2555 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2556 length for maximum padding up to 128 bytes). Affected
2557 file lib/silccore/silcpacket.h.
2559 * Removed all backwards support for old 0.5.x MAC thingies.
2560 The SILC packet header change makes it impossible to be
2561 backwards compatible.
2563 * Send the ENDING packet with timeout in the backup resuming
2564 protocol. This is to assure that all routers has connected
2565 to the primary router. Affected file silcd/server_backup.c.
2567 * Changed the RNG to take the first IV from random data. It
2568 used to take it from zero actually. Changed the RNG also
2569 to use /dev/urandom during session. /dev/random is used
2570 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2572 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2574 * Changed the SILC packet header to have the first two bytes
2575 (the packet length) encrypted. Affected files aroung the
2576 code tree, lib/silccore/silcpacket.[ch]. Removed the
2577 SilcPacketCheckDecrypt callback. It is not needed anymore
2578 since the silc_packet_receive_process will determine now
2579 whether the packet is normal or special.
2581 * Implemented the unidirectional MAC keys. Affected files
2582 lib/silcske/silcske.c, silcd/protocol.c and
2583 lib/silcclient/protocol.c.
2585 * Implemented the packet sequence number to the MAC computation.
2586 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2587 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2588 lib/silcclient/protocol.c.
2590 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Allow backup router to announce servers. All servers
2593 announced by backup router are added to the global list
2594 automatically. Update hte server's socket to our primary
2595 router also when backup router announces a server.
2596 Affected file silcd/packet_receive.c.
2598 * Do not update the client->router in the function
2599 silc_server_udpate_clients_by_server if the client is on
2600 global list. We might fail to find any specific server
2601 for locally connected clients and local cell clients. They
2602 should still use the `from' and not `to' as client->router.
2603 This fixes backup router resuming protocol. Affected file
2604 silcd/server_util.c.
2606 * Decrease channel statistics count only if the channel
2607 deletion worked. Affected files are silcd/server.c and
2608 silcd/server_util.c.
2610 * Added silc_server_update_servers_by_server to update origin
2611 of all server entries. Used during backup router protocol.
2612 Affected files silcd/server_util.[ch], silcd/server.c. and
2613 silcd/backup_router.c.
2615 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2616 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2617 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2618 lib/silccrypt/silchmac.c.
2620 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2622 * Assure that router cannot reroute the same channel message
2623 to the sender. Affected file silcd/packet_receive.c.
2625 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2627 * Made better checks that the channel message is not sent
2628 to the router it came from. Affected file is
2629 silcd/packet_send.c. Fixed memory leak too.
2631 * Announce informations for incoming router connection, but
2632 only after checking if it is replaced by backup router.
2633 Affected file silcd/packet_receive.c.
2635 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2637 * Fixed the backup resuming protocol to work in multiple
2638 router environment. Affected file silcd/server_backup.c.
2640 * Route packet only to one router in the function
2641 silc_server_packet_send_to_channel. Affected file is
2642 silcd/packet_send.c.
2644 * Fixed silc_server_send_notify_dest to set the broadcast
2645 flag. Fixed the silc_server_send_notify_topic to actually
2646 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2647 Affected file silcd/packet_send.c.
2649 * Changed the SFTP Filesystem interface. Changed the
2650 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2651 the filesystem operation function. The SilcSFTPFilesystem
2652 is now a context that is allocated by all filesystem allocation
2653 functions and it already includes the operations structure
2654 and filesystem specific context. It is given as argument
2655 now to the silc_sftp_server_start. This made the interface
2656 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2657 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2659 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Changed the backup router adding and getting interfaces
2662 in the server. The router that will be replaced by the
2663 specified backup router is now sent as argument. Affected
2664 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2667 * Added silc_net_addr2bin_ne to return the binary form of
2668 the IP address in network byte order. Affected files
2669 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2671 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2673 * Check for existing server ID in silc_server_new_server
2674 and in silc_server_connect_to_router_final and remove the
2675 old entry if it exists. Affected file silcd/packet_receive.c,
2678 * Send the channel message always to only one router, either
2679 in upstream or downstream. Affected file is
2680 silcd/packet_send.c.
2682 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2684 * Wrote the definition of the backup resuming protocol to the
2685 protocol specification.
2687 * Removed one redundant channel key generation from normal
2688 server during joining procedure. Removed one redundant
2689 channel key sending from server to router during joining
2690 procedure. Affected file silcd/command.c.
2692 * Made minor bugfixes to the backup router resuming protocol.
2693 Affected file silcd/server_backup.c, server.c.
2695 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2697 * Added --disable-asm configuration option. Affected files
2698 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2701 * Implemented the backup resuming protocol that is used to
2702 resume the primary router position in the cell after the
2703 primary router comes back online. Affected files
2704 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2705 and silcd/server_util.[ch].
2707 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2709 * Sleep two (2) seconds after sending QUIT command to server.
2710 Affected file lib/silcclient/command.c.
2712 * Assure that if outgoing data buffer is pending do not force
2713 send any data. Affected file silcd/packet_send.c.
2715 * Assure that if outgoing data buffer is pending do not force
2716 send any data. Affected file lib/silcclient/client.c.
2718 * Implemented the backup router support when the primary router
2719 goes down. The servers and routers can now use the backup
2720 router as new primary router without loosing connectivity.
2722 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2724 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2725 in the server to indicate disabled entry. All data read
2726 from the connection will be ignored and no data is sent
2727 for entry that is disabled. Affected files are
2728 silcd/idlist.h, silcd/server.c.
2730 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * Created SFTP client and server test programs in the
2733 lib/silcsftp/tests directory.
2735 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2737 * Implemented memory filesystem (virtual filesystem) for
2738 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2741 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Implemented the SFTP (SSH File Transfer Protocol) to the
2744 lib/silcsftp. It includes SFTP client and SFTP server
2747 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2749 * Moved lib/silccore/silcprotocol.[ch] to the
2750 lib/silcutil library.
2752 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2753 take variable argument list pointer as argument. Affected
2754 file lib/silcutil/silcbuffmt.[ch].
2756 * Added silc_buffer_set function that is used to set data
2757 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2758 Affected file lib/silcutil/silcbuffer.h.
2760 * Changed various routines in the core library to use the new
2761 silc_buffer_set instead of allocating new buffer only for
2764 * Added 64-bit value formatting and unformatting support to the
2765 silc_buffer_[un]format routines. Affected file is
2766 lib/silcutil/silcbuffmt.[ch].
2768 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2769 to includes/bitmove.h.
2771 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2773 * Fixed channel user mode saving in client library. Affected
2774 file lib/silcclient/command[_reply].c.
2776 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Defined the file transfer to the SILC Protocol. Added
2779 new packet type SILC_PACKET_FTP and defined File Transfer
2780 Payload. The mandatory file transfer protocol is SFTP
2781 (SSH File Transfer Protocol). Affected file in addition
2782 of the internet draft is lib/silccore/silcpacket.h.
2784 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2785 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2786 is used as part of backup router protocol when the primary
2787 router of the cell is back online and wishes to resume
2788 the position as primary router.
2790 * Redefined the MAC generation keys in the protocol. The
2791 same key is not used anymore in both direction. Both
2792 direction will now use different keys for sending and
2793 receiving. This fixes a potential security flaw. This
2794 change causes incompatibilities in the protocol.
2796 * Redefined also the MAC computation from the packet.
2797 An packet sequence number is now added to the MAC
2798 computation. This prevents possible replay attacks against
2799 the protocol. This change too causes incompatibilities
2802 Added `sequence' field to the SilcPacketContext to hold
2803 the current sequence number for the packet.
2805 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Added `created' field to the SilcIDListData in the file
2808 silcd/idlist.h to indicate the time when the entry was
2811 * Added `created' field to the SilcChannelEntry too. Affected
2812 file silcd/idlist.h.
2814 * Added `creation_time' aguments to all the announcement functions
2815 in the server. If it is provided then only the entries that
2816 was created after the provided time frame are actually
2817 announced. Affected file silcd/server.[ch].
2819 * The protocol says that the Channel ID's IP address must be
2820 based on the router's IP address. Added check for this in
2821 the silc_server_new_channel when processing incoming New Channel
2822 Payload. Affected file silcd/packet_receive.c.
2824 * Print out the correct version with --version in SILC client.
2825 Affected file irssi/src/silc/core/silc-core.c.
2827 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Fixed WHOWAS command to check for completnes of the client
2830 entry always, not just when the command is coming from client.
2831 Affected file silcd/command.c.
2833 * Added new function silc_server_packet_queue_purge to purge the
2834 outgoing data queue to the network. After the function returns
2835 it is guaranteed that the outgoing packet queue is empty.
2836 Affected file silcd/packet_send.[ch].
2838 * Purge the outgoing packet queue in the rekey protocol's final
2839 callback to assure that all rekey packets go to the network
2840 before quitting the protocol. Affected file silcd/server.c.
2842 * Added silc_client_packet_queue_parse as similar function as
2843 in server to the client library. The affected file is
2844 lib/silcclient/client.c.
2846 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * Splitted silcd/server.c and created silcd/server_util.[ch]
2849 for utility functions.
2851 * Added new socket flag SILC_SF_DISABLED to indicate that the
2852 connection is open but nothing can be sent to or received from
2853 the connection. Affected file lib/silcutil/silsockconn.[ch].
2854 The checking for disabled socket is checked in the low level
2855 silc_socket_write and silc_socket_read functions.
2857 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2859 * Allow only nicknames and channel names that fits into the
2860 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2862 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * When processing JOIN command reply in server check that if
2865 the channel exists in our global list we'll move it the local
2866 list. Affected file silcd/command_reply.c.
2868 * Fixed the check whether client is joined on the channel already
2869 in JOIN command. Affected file lib/silcclient/command.c.
2871 * Fixed the JOIN command reply to check whether the channel
2872 already exists. Affected file lib/silcclient/command_reply.c.
2874 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2876 * Added silc_ske_status_string to map the SKE error numbers
2877 to readable strings. The affected files are
2878 lib/silcske/silcske[_status].[ch].
2880 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Do not show the private channels on the WHOIS channel list
2883 as it is not allowed by the protocol. The affected file is
2886 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2888 * Assure that the packet length digged from the actual packet
2889 is something sensible in the silc_packet_decrypt_rest_special
2890 in lib/silccrypt/silcpacket.c.
2892 * Free and NULL the allocated pointer in silc_hmac_alloc if
2893 the HMAC allocation fails. The affected file is
2894 lib/silccrypt/silchmac.c.
2896 * Print the selected security properties to the log files in
2897 the server. Affected file silcd/protocol.c.
2899 * Add SKE's reference counter even if calling the completion
2900 callback manually. Otherwise it goes negative, although it
2901 does not cause any problems. The affected file is
2902 lib/silcske/silcske.c.
2904 * Remove the client entry with short timeout after giving the
2905 KILL command. Affected file lib/silcclient/command.c.
2907 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2908 case all found clients are already disconnected (WHOWAS would
2909 found them) in the server. Affected file silcd/command.c.
2911 * Update the last_receive (time of last data received) to be
2912 updated only when received private or channel message so that
2913 the idle time showed in WHOIS makes more sense.
2915 * Added boolean field `valid' in to the SilcClientEntry in the
2916 client library to indicate whether the entry is valid or not.
2917 This fixes the nickname change bug on channel when changing
2918 the nickname to be same than the old (like nick to Nick) the
2919 nickname formatter doesn't set the new nick anymore to Nick@host.
2920 Affected file lib/silcclient/idlist.[ch].
2922 * Now actually fixed the nickname changing on disconnection.
2923 Added new function silc_change_nick to the Irssi SILC Client.
2924 Affected file irssi/src/silc/core/client_ops.c,
2925 irssi/src/silc/core/silc-nicklist.[ch].
2927 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Check that the public key exists in the GETKEY command before
2930 trying to encode it. Affected file silcd/command.c.
2932 * Print some notifications on received public keys with GETKEY
2933 command in the Irssi SILC Client. Affected files are
2934 irssi/src/fe-common/silc/module-formats.[ch],
2935 irssi/src/silc/core/client_ops.c.
2937 * Use IDENTIFY command to resolve the server information in the
2938 GETKEY command instead of INFO command. Affected file
2939 lib/silcclient/command.c.
2941 * All command reply functions in the client library now calls
2942 the pending command reply callbacks even if an error has
2943 occurred. The server has done this a long time and now it was
2944 time to move the client library to this as well. Now all
2945 errors can be delivered back to the pending command reply
2946 callbacks if necessary. Affected files are
2947 lib/silcclient/command[_reply].[ch].
2949 * Change the nickname on disconnection back to the username
2950 because in reconnect the server will enforce it to it anyway.
2951 Affected file irssi/src/silc/core/silc-servers.c.
2953 * Fixed a config file parsing bug in the Irssi SILC client.
2954 Affected file irssi/src/silc/core/clientconfig.c.
2956 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * When printing the channel mode on JOIN, verify that the
2959 channel key and channel's HMAC are valid. Affected file
2960 irssi/src/silc/core/client_ops.c.
2962 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2964 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2965 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2966 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2968 * Removed channel key rekey task deleting from the function
2969 silc_server_save_channel_key. Affected file silcd/server.c.
2970 Added explicit timeout task context instead that is used to
2971 delete the task if we are registering a new task before the
2972 new task has elapsed.
2974 * When channel key rekey occurs the client library now saves
2975 the old channel key for a short period of time (10 seconds) and
2976 is able to use it in case some is still sending channel
2977 messages encrypted with the old key after the rekey. Affected
2978 file lib/silcclient/[idlist.h|client_channel.c].
2980 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2982 * Added check to the silc_server_new_id_real to not accept
2983 new ID if it is the sender's own ID. Affected file is
2984 silcd/packet_receive.c.
2986 * Assure that we do not announce ourself or the one we've
2987 sending our announcements when we're router and are announcing
2988 servers to our primary router. Affected file silcd/server.c.
2990 * Fixed silc_server_command_identify_check_client to assemble
2991 correct WHOIS packet. It send corrupted WHOIS packet and
2992 caused problem with router to router connections. Affected
2993 file silcd/command.c.
2995 Fixed also silc_server_command_whois_check the same way
2996 as for the IDENTIFY command.
2998 * Added new SilcIDListStatus to the server in the SilcIDListData
2999 structure. The status now includes the current status of
3000 the entry (like registered, resolved etc.). Affected file
3001 silcd/idlist.[ch]. Defined a bunch of different status types
3002 as well. This replaced the old boolean registered field as well.
3004 Added resolve_cmd_ident field to the SilcClientEntry structure
3005 too so that if the entry is for example being resolved so
3006 another command may attach to the same pending command reply
3007 without requiring to resolve the same entry again. This concept
3008 should optimize the WHOIS and the IDENTIFY resolving under
3009 heavy load by taking away unnecessary resolving for entries
3010 that are being resolved already.
3012 Added support for adding multiple pending commands for one
3013 command idenfier. Affected file silcd/command[_reply].[ch].
3015 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3016 before deleting the data. Otherwise the hash table will have
3017 freed data in comparison functions. Affected file is
3018 silcd/command_reply.c.
3020 * Fixed silc_idlist_replace_client_id to add the new entry to
3021 the cache with NULL nickname. Otherwise there will be invalid
3022 memory as the nickname after the nickname is freed. Affected
3023 file silcd/packet_receive.c.
3025 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3026 saved into wrong slots because the previous number of entries
3027 was not taken into account. Affected file silcd/idlist.c.
3028 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3030 * If we are router and we receive JOIN notify to a channel that
3031 does not have any users then notified client is marked as the
3032 channel founder, as it is it. The affected file is
3033 silcd/packet_receive.c
3035 * Added to the extended hash table API's table_del_*ext functions
3036 the destructor as argument too, so that the caller can decide
3037 which destructor to use or whether to use destructor at all.
3038 Affected file lib/silcutil/silchashtable.[ch].
3040 * Fixed ID Cache purging. It actually deleted the entries from
3041 the hash table after the data was freed. The hash table ended
3042 up comparing freed memory. The affected file is
3043 lib/silccore/silcidcache.c.
3045 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3047 * Fixed Irssi SILC client's KILL command's HELP syntax.
3049 * The USERS command now resolves the detailed user information
3050 if the userinfo field is missing. Affected file is
3051 lib/silcclient/command_reply.c.
3053 * Do not print error in silc_file_read if the read file does
3054 not exist. Just silently return NULL. Affected file is
3055 lib/silcutil/silcutil.c.
3057 * Fixed the silc_log_output to not wine about NULL filename
3058 and to not create some bogus " " filename. Affected file is
3059 lib/silcutil/silclog.c.
3061 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3063 * Fixed various printing bugs on the user interface in the
3064 Irssi SILC Client. Minor changes that were forgotten from
3067 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3069 * Fixed the configure.in.pre and the compilation and distribution
3070 environment to support the new autoconf 2.52. That version is
3071 now required to compile the CVS trunk.
3073 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3076 to generally parse user@fqdn format strings. Affected file
3077 lib/silcutil/silcutil.c.
3079 * Added nickname_format and nickname_force_format fields to the
3080 SilcClientParams structure. The first one defines the format
3081 for the nicknames that the library will enforce if the receives
3082 multiple same nicknames. The second one is boolean value and
3083 can be used to force the library to always enforce the format
3084 to the nicknames regardles whether there are multiple nicknames
3085 or not. This configurable formatting was employed to flexibly
3086 support accessing multiple nicknames from the user interface.
3087 The userinterface can now set the nicknames to what ever format
3088 they prefer. Affected file lib/silcclient/silcapi.h.
3090 Added function silc_client_nickname_format to the file
3091 lib/silcclient/idlist.c. It performs the nickname formatting.
3093 Added new field `hostname´ to the SilcClientEntry context.
3094 It holds the hostname of the client. Affected file is
3095 lib/silcclient/idlist.h.
3097 * Irssi SILC Client sets the nicknames in nick@hostn format.
3098 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3099 irssi/src/silc/core/silc-core.c.
3101 The WHOIS printing now also shows both the real nickname and
3102 the formatted nickname so that user knows how to access the
3103 user if there are multiple same nicknames cached. Affected
3104 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3105 printing formatting too to take the hostname now as a separate
3106 argument. The Affected file is
3107 irssi/src/fe-common/silc/modules-formats.[ch].
3109 * Changed the silc_client_get_clients_local to accept the formatted
3110 nickname as argument. It accepts the real nickname too but the
3111 formatted nickname can be used to find the true entry from
3112 multiple entries. Affected file lib/silcclient/silcapi.h and
3113 lib/silcclient/idlist.c.
3115 * Added nickname_format_parse field to the SilcClientParams.
3116 It is a callback function provided by the application to parse
3117 the nickname out of the formatted nickname string. The library
3118 calls it to get the nickname from the formatted string. Since
3119 the application generally knows better the format of the nickname
3120 string it parses it instead of the library, even though library
3121 encodes the formatted string. If the callback function is not
3122 provided then the library will use the string as is. The
3123 affected file is lib/silcclient/silcapi.h.
3125 * All the nickname strings passed to the client library in
3126 commands are now expected to be formatted nickname strings.
3127 If the command does not support the formatted nickname string
3128 it will assume that the sent string is the actual nickname.
3129 Affected file lib/silcclient/command.c.
3131 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Added public key authentication support to OPER and SILCOPER
3134 commands in the client library. Affected file is
3135 lib/silcclient/command.c.
3137 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3139 * Changed the get_auth_methdod client operation to be asynchronous.
3140 It can be async if the application resolves the authentication
3141 method from the server during the negotiation. Added new
3142 SilcGetAuthMeth completion callback that the application will
3143 call after resolving the authentication method.
3145 Added function silc_client_request_authentication_method that
3146 the application can use to resolve the authentication method
3147 from the server. Added also SilcConnectionAuthRequest callback
3148 that the library will call after the server has replied. The
3149 application can call this function if it does not know the
3150 current authentication method.
3152 Affected files are lib/silcclient/client.c and
3153 lib/silcclient/silcapi.h.
3155 * The Irssi SILC client now automatically resolves the authentication
3156 method incase any configuration information is not present (and
3157 currently there never is). The affected file is
3158 irssi/src/silc/core/client_ops.c.
3160 * Fixed public key authentication from the client library.
3161 Affected file lib/silcclient/protocol.c. Changed also the
3162 protocol specification about the public key authentication in
3163 the connection authentication protocol. The actual data to be
3164 signed is now computed with a hash function before signing.
3166 * Fixed the public key authentication from the server as well.
3167 Affected file silcd/protocol.c.
3169 * Removed the mlock()'s from the memory allocation routines.
3170 Affected file lib/silcutil/silcmemory.c. The ./configure does
3171 not check anymore for the mlock(). Affected file is
3174 * Fixed USERS command in server to allow the execution of the
3175 command for private and secret channels if the client sending
3176 the command is on the channel. Affected file silcd/command.c.
3178 * Fixed silc_client_get_clients_local to return the clients
3179 count correctly. It could return wrong value. Affected file
3180 lib/silcclient/idlist.c.
3182 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3185 types. The assembler optimizations seemed not to like 64-bit
3186 data types. The assmebler optimizations thus are now enabled
3187 also for BSD systems as opposed to only enable them for Linux.
3189 * Do not check for threads at all on BSD systems. Affected
3190 file configure.in.pre.
3192 * Removed -n and -h options from the Irssi SILC Client since
3193 they are not used in silc.
3195 * Fixed the prime generation to assure that the first digit
3196 of the generated random number is not zero since our conversion
3197 routines does not like number strings that starts with zero
3198 digit. If zero digit is seen the random number is regenerated.
3199 This caused some corrupted RSA keys when the zero first digit
3200 was met. Affected file lib/silcmath/silcprimegen.c.
3202 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3204 * Fixed WIN32 configuration in the ./configure script.
3205 Fixed to include xti.h on environments that has it.
3206 Patches by Carsten Ilchmann and andrew.
3208 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3210 * Changed the silc_id_create_client_id to be collision
3211 resistant. It is now assured that there cannot be created
3212 two same client ID's. I suspect that some weird bugs in
3213 the server were actually caused by duplicate Client IDs.
3214 Affected file silcd/serverid.[ch]. A router receiving
3215 new ID now also assures and informs the sending server
3216 if the ID caused collision.
3218 * Changed the silc_id_create_channel_id to also assure that
3219 there are no collisions.
3221 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Statement about ignoring the Mutual Authentication flag when
3224 performing rekey with PFS was a bit misleading. It is ignored
3225 if it was set in the initial negotiation, it cannot be even
3226 set in the rekey. Fixed in the ke-auth draft. Started the
3227 new versions of the protocol drafts in the doc/.
3229 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3231 * Fixed a bug in silc_client_command_identify_save when saving
3232 new channel information. The channel name was no duplicated
3233 and caused crash on exit. Affected file is
3234 lib/silcclient/command_reply.c.
3236 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Fixed the getkey command handling in the server. Send just
3239 empty OK reply to the sender if the key could not be fetched
3240 (but everything else was ok, like the key just was not available).
3241 Changed the public key parameter to optional in the protocol
3242 specs so that empty OK reply can be sent. Affected file
3245 Added a message to Irssi SILC client to tell to user if the
3246 server did not return a public key.
3248 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3250 * Fixed a channel key regeneration bug. It registered new
3251 timeout tasks exponentially until all system resources were
3252 used. Affected file silcd/server.c.
3254 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3256 * Added the SILC Document generator to the scripts/silcdoc.
3257 It can be used to generate the Toolkit Reference Manual out
3258 of the source tree. Internally it will also use the RoboDoc
3259 generator now imported in util/robodoc.
3261 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3263 * Added couple of return's in rekey protocol if error orccurred
3264 during the protocol. The execution must be terminated.
3265 Affected file silcd/protocol.c. Also, terminate the protocol
3266 always with timeout.
3268 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3270 * The client's Client ID was created initally from the wrong
3271 nickname (it could have been in format nick@host) in the
3272 silc_server_new_client. Affected file silcd/packet_receive.c
3274 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3276 * Added some SILC_LOG_ERROR's to various error conditions
3277 if client could not be added to ID cache. Affected files
3278 silcd/packet_receive.c and silcd/server.c.
3280 * When client's sock->user_data is freed, NULL also the
3281 client->router and client->connection pointers. Added check
3282 for these pointers being NULL to various places around the
3283 code. Affected file silcd/server.c.
3285 * Added client->data.registered == TRUE checks to various
3286 places around the code to assure that unregistered client's
3287 are not handled when it is not allowed. Affected file
3290 * Added `bool registered' fields to all
3291 silc_idlist_[server|client]_get_* routines to indicate whether
3292 the fetched client needs to be registered or not. Affected
3293 file silcd/idlist.[ch].
3295 * Add your own entry as registered to the ID cache in the
3296 server. Affected file server.c.
3298 * Fixed a bug in silc_server_new_server. The SilcServer was
3299 set as the new server's context instead of SilcServerEntry.
3300 This naturally caused some weird bugs.
3302 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3304 * Do not delete the channel rekey task when adding it
3305 for in silc_server_create_channel_key.
3307 * Changed the silc_server_create_channel_key to return
3308 TRUE or FALSE to indicate the success of the channel key
3311 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3313 * Fixed MSVC++ project files and added missing files to
3314 Makefiles under win32/.
3316 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * Do not add TCP_NODELAY flag if the operating system
3319 does not have it defined. Affected files are
3320 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3322 * Fixed buffer overflow from Irssi SILC Client. Affected
3323 file irssi/src/fe-common/core/themes.c.
3325 * Fixed double free in client library in the file
3326 lib/silcclient/client.c when disconnecting from server.
3328 * Applied double free patch from cras to Irssi SILC client.
3329 Affected files irssi/src/core/[modules/expandos].c
3331 * Fixed the disconnection handling to Irssi SILC Client.
3332 The application must call silc_client_close_connection
3333 in ops->connect client operation in case of failure of
3334 the connection. Affected file is
3335 irssi/src/silc/core/client_ops.c.
3337 * Do not set sock->protocol to NULL in the function
3338 silc_client_close_connection after executing the protocol's
3339 final callback since the sock might not be valid anymore.
3340 Affected file lib/silcclient/client.c.
3342 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3344 * Do not enable SILC_THREADS if the linking with libpthread
3345 did not happen. Affected file configure.in.pre.
3347 * Added notion to protocol specification that server must
3348 verify the sent authentication payload with CMODE when
3349 setting the channel founder key. Implemented it to the
3350 server. Affected file silcd/command.c.
3352 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * Added _EXTRA_DIST SILC distribution variable to the
3355 distributions file. It is used to conditionally add extra
3356 files or directories to the specific distribution. Affected
3357 files ./prepare, Makefile.am.pre and distributions.
3359 Removed the `_' from the start of the distribution names.
3362 * Added README.WIN32 for instructions to compile the Toolkit
3365 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3367 * Fixed a double free in disconnection in the server. Affected
3368 file is silcd/server.c.
3370 * Fixed the lib/silcske/groups.c to work now also with GMP
3371 MP library. The string conversion did not work when using
3372 specific base and the base is indicated in the string as well.
3374 * Created win32/ directory which now includes MSVC++ specific
3375 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3376 It will appear only in the toolkit distribution
3378 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3380 * Changed the key material distribution function in case when
3381 the hash output is too short. The data is now concatenated
3382 a bit differently than it used to. Made the change to the
3383 SKE protocol specification.
3385 * Added better GMP detection to configure.in.pre. A patch
3388 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3390 * Fixed a minor bug in SKE that might cause some problem on
3391 some platforms. Affected file lib/silcske/silcske.c.
3393 * Added the cookie checking for initiator in the SKE. It checks
3394 that the responder returns the sent cookie unmodified. The
3395 affected file is lib/silcske/silcske.c. Added new SKE
3396 error type INVALID_COOKIE that can be sent during the
3397 negotiation. Fixed some memory leaks as well.
3399 * Added the "invalid cookie" error message to Irssi SILC client's
3402 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3404 * Added `task_max' field to the SilcClientParams to indicate
3405 the maximum tasks the scheduler can handle. If set to zero,
3406 default values are used. Affected file lib/silcclient/silcapi.h.
3408 * Fixed memory leaks in silc_client_close_connection. Affected
3409 file lib/silcclient/client.c.
3411 * Added silc_client_del_client_entry to client library to free
3412 all memory of given client entry. Affected file is
3413 lib/silcclient/idlist.[ch].
3415 * Added new functions silc_client_del_channel and
3416 silc_client_del_server to delete channel and server entries.
3417 Affected file lib/silcclient/[silcapi.h/idlist.c].
3419 * Removed silc_client_del_client_by_id from silcapi.h.
3421 * Fixed the INFO command to return the server's own info
3422 correctly when querying by Server ID. Affected file is
3425 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3427 * Removed the non-blocking settings in WIN32 code in the
3428 silc_sock_[read/write] and added SleepEx instead. Affected
3429 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3430 of input data is now checked with FIONREAD and ioctlsocket.
3432 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3434 * Call silc_schedule_task_del_by_context in the
3435 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3436 Affected file lib/silccore/silcprotocol.c.
3438 * Call silc_protocol_cancel for active protocols in the
3439 silc_server_close_connection if the funtion
3440 silc_server_free_sock_user_data has not been called.
3441 Affected file silcd/server.c.
3443 * Generic tasks cannot be deleted using the del_by_fd
3444 task deleting function since generic tasks does not match
3445 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3447 * Added a notion to SILCOPER help file that the SILCOPER works
3448 only on router server, not on normal server.
3450 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3452 * Added for WIN32 support for the new scheduler as well.
3453 Affected file lib/silcutil/win32/silcwin32schedule.c.
3455 * Fixed the SHA1 implementation to work on various platforms.
3457 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3460 API. It is part of the scheduler now. Everything else is
3461 as previously but some functions has changed their names.
3462 Checkout the lib/silcutil/silcschedule.h for the interface.
3463 Updated all applications to use the new interface. Affected
3464 files are lib/silcutil/silcschedule.[ch].
3466 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3468 * Found a bug in the SKE implementation. The HASH value,
3469 specified by the protocol, was not computed correctly. The
3470 public key of the responder was not added to the computation
3471 even though it is mandatory. Affected file lib/silcske/silcske.c.
3472 This unfortunately causes incompatibilities with older
3473 clients and servers.
3475 * Added WIN32 specific network init and uninit functions:
3476 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3477 the Winsock2. Affected file lib/silcutil/silcnet.h and
3478 lib/silcutil/win32/silcwin32net.c.
3480 * Set the socket always to nonblocking mode on WIN32 after
3481 reading data or writing data. Affected file is
3482 lib/silcutil/win32/silcwin32sockconn.c.
3484 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3486 * Fixed various compilation problems under WIN32. Affected
3487 files lib/silcutil/win32/silcwin32thread.c and
3488 lib/silcutil/win32/silcwin32schedule.c.
3490 * Removed all _internal.h #includes from public header
3491 files. Internal headers must never be included from
3494 Removed also the lib/silcske/payload_internal.h file.
3496 * All include files that may be needed (public and some others
3497 included by the public headers) by application developers are
3498 now copied to the ./includes directory. It does not copy any
3499 internal headers. Affected file Makefile.defines.pre and all
3500 Makefile.am's under lib/ and subdirs.
3502 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Do not change the ~/.silc directory's permissions automatically.
3505 Affected file irssi/src/silc/core/clientutil.c.
3507 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3509 * Do not cancel the protocol in silc_server_close_connection
3510 it might cause recursion. Now cancelled in the function
3511 silc_server_free_sock_user_data. Affected file silcd/server.c.
3513 * Fixed the silc_server_remove_clients_by_server to regenerate
3514 the channel keys correctly finally. Added also new function
3515 silc_server_remove_clients_channels to actually do it.
3516 Affected file silcd/server.c.
3518 * Fixed the silc_server_new_channel to not crash by giving
3519 wrong router to the new channel. Affected file is
3520 silcd/packet_receive.c.
3522 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3524 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3525 which is given as argument to the silc_client_alloc now.
3526 It can be used to configure the client and set various parameters
3527 that affect the function of the client.
3529 * The USERS command in server did not check whether the channel
3530 is private or secret. Affected file silcd/command.c.
3532 * Added new argument to the USERS command in protocol specification.
3533 The USERS command now can take the channel name as argument
3534 as well. Added support for this in client and server and
3535 updated the protocol specs.
3537 * Completed the GETKEY command in client. It can be now used
3538 to fetch also servers public key not only some clients.
3539 Affected files lib/silcclient/command[_reply].c.
3541 * Added silc_client_get_server to return server entry by the
3542 server name. Affected files lib/silcclient/silcapi.h and
3545 * Redefined the IDENTIFY command in protocol specification to be
3546 more generic. It now can be used to query information about
3547 any entity in the SILC Network, including clients, servers and
3548 channels. The query may be based either the entity's name
3549 or the ID. Added support for this in both client and server.
3551 Affected files silcd/command.c and lib/silcclient/command.c
3552 and command_reply.c.
3554 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3555 the _from_client and _from_server functions. Affected file
3558 * Added silc_client_get_channel_by_id_resolve to the file
3559 lib/silcclient/silcapi.h to resolve channel information by
3560 its ID. Added also silc_client_get_channel_by_id that
3561 does not resolve it from the server.
3563 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3565 * Added SilcServerEntry context into the client library
3566 to represent one server. The INFO command now allocates
3567 these to save the resolved server info. For now on the
3568 client library will also keep information about servers,
3569 connected and resolved with INFO.
3571 The INFO command now allocates the SilcServerEntry context
3572 and saves the server info there. The COMMAND_REPLY in
3573 the INFO now returns the parameters to application in
3574 same order as defined in the protocol specification.
3576 The entries are cached in the client->server_cache.
3578 * The INFO command is now issued after received the Client ID
3579 from the server. Affected file lib/silcclient/client.c.
3581 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3582 to the application as the mode changer might be server.
3583 It is guaranteed that NULL is not returned anymore to the
3584 application. Affected file lib/silcclient/client_notify.c.
3586 The ID Type is now also passed to the application so that
3587 it can check whether the returned entry is SilcClientEntry
3590 Added new function silc_client_get_server_by_id to return
3591 the server entry by ID. Affected files are the
3592 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3594 * Do not create the channel in the Irssi SILC Client when issuing
3595 the JOIN command but when received the sucessful JOIN command
3596 reply. Otherwise the channel might get created even though we
3597 could not join it. The Affected file is
3598 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3600 * Fixed a channel joining bug in router. The router must also
3601 check the channel modes, invite and ban lists etc. when serving
3602 the JOIN command sent by normal server. Affected file is
3603 silcd/command.c. The router now resolves the client's
3604 information from the server who sent the JOIN command if it
3605 does not know it, and processes the JOIN command only after
3608 * Changed the SilcCommandCb to take new argument; void *context2.
3609 Affected file lib/silccore/silccommand.h
3611 The second argument in the command callbacks in the server now
3612 includes the SilcServerCommandReplyContext if the command was
3613 called as pending command callback from the command reply.
3614 Otherwise it is NULL. When called as pending the status of the
3615 command reply will be checked and if it was erronous the
3616 error will be sent to the original sender of the command.
3617 This way the client always receives the error messages even
3618 though the server was actually the one who received the error
3619 when it resent the command to router, for example. Affected
3620 files silcd/command[_reply].[ch].
3622 * Fixed sending WHOWAS command's error message to client if
3623 the requested client could not be found. It was missing.
3626 * Changed the CMODE and CUMODE commands reply arguments in the
3627 protocol specification. The Channel ID is now sent in both
3628 of the commands to identify the channel. Implemented this
3629 new feature to the client and server. Affected files
3630 lib/silcclient/command_reply.c and silcd/command.c.
3632 * Made better checks for invite and ban lists in the JOIN
3633 command in server. Affected file silcd/command.c.
3635 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3637 * The server now performs the incoming host IP/DNS lookup
3638 using the silc_socket_host_lookup and thus does not block
3639 the server anymore. Affected file silcd/server.c.
3641 * Completed the multi-thread support for SILC Scheduler in
3642 the lib/silcutil/silcschedule.c.
3644 * Fixed the configure.in.pre to detect the pthread correctly
3647 * Fixed a deadlock in silc_task_queue_wakeup in the file
3648 lib/silcutil/silctask.c.
3650 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3652 * Added new function silc_schedule_wakeup that is used in
3653 multi-threaded environment to wakeup the main thread's
3654 schduler. It needs to be used when a thread adds a new task
3655 or removes a task from task queues. After waking up, the
3656 scheduler will detect the task queue changes. If threads
3657 support is not compiled in this function has no effect.
3658 Implemented the wakeup mechanism to both Unix and WIN32
3659 systems. Affected files are lib/silcutil/silcschedule.[ch],
3660 lib/silcutil/unix/silcunixschedule.c and the
3661 lib/silcutil/win32/silcwin32schedule.c.
3663 * Added new function silc_task_queue_wakeup to wakeup the
3664 scheduler by the specified task queue. Affected file
3665 lib/silcutil/silctask.[ch].
3667 * The silc_socket_host_lookup_start now wakes up the scheduler
3668 after adding the timeout task. Affected file is
3669 lib/silcutil/silcsockconn.c.
3671 * The silc_socket_host_lookup is synchronous now if the threads
3672 support is not compiled in. However, the callback is still
3673 called asyncronously through the scheduler, anyway. Affected
3674 file lib/silcutil/silcsockconn.c.
3676 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3678 * Added new function silc_socket_host_lookup to perform
3679 asynchronous IP and FQDN lookups for the socket connection.
3680 Affected files lib/silcutil/silcsockconn.[ch].
3682 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3684 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3685 that may or may not compile the mutex support in.
3687 Changed the silc_mutex_alloc interface. It allocates the
3688 mutex now to the sent pointer and returns TRUE or FALSE.
3690 Affected file lib/silcutil/silcmutex.h.
3692 * Wrote the SILC Task Queue interface to support multi-threads.
3693 Affected file lib/silcutil/silctask.[ch].
3695 * Wrote the SILC Scheduler to support multi-threads. Affected
3696 file lib/silcutil/silcschedule.c.
3698 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3700 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3701 in lib/silcutil/win32/.
3703 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3705 * Defined SILC Mutex API and SILC Thread API and implemented
3706 them for Unix. Affected files are
3707 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3708 lib/silcutil/unix/silcunixmutex.c and
3709 lib/silcutil/unix/silcunixthread.c.
3711 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3713 * Fixed the silc_server_remove_clients_by_server's channel
3714 key re-generation. The hash table handling was incorrect
3715 and would not work with many channels. Affected file is
3718 * Fixed some memory leaks around the server code.
3720 * Rewrote the silc_server_get_users_on_channel to support IPv6
3721 based Client ID's. Affected file silcd/server.c.
3723 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3724 specification. However, a separate document must be written
3725 to define the detailed signing procedure and the payload
3726 associated with the flag. Defined the flag to the
3727 lib/silccore/silcchannel.h as well.
3729 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3731 * Changed the dynamic tables to static size tables in the
3732 lib/silccrypt/silchmac.c.
3734 * Removed GCC dependencies from the code. A patch by cras.
3736 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3738 * Do not show the error "Error receiving packet bla bla"
3739 in server if it really was not an error (-2 means that reading
3740 is pending). Affected file silcd/server.c.
3742 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3744 * Fixed a possible crash in silc_server_remove_clients_by_server
3745 in silcd/server.c. Fixed there also some memory leaks.
3747 * Fixed the silc_idlist_replace_client_id. It could replace
3748 wrong key in the hash table. Affected file silcd/idlist.c.
3750 * Do not check whether there are global users on the channel
3751 if the channel->global_users is FALSE. Affected functions
3752 silc_server_remove_from_one_channel and
3753 silc_server_remove_from_channels in silcd/server.c. Also,
3754 do not check if the removed client is local as we can be
3755 sure that global client was not removed from the channel
3756 and checking for global users is not needed.
3758 * The silc_server_remove_clients_by_server now re-generates
3759 the channel keys correctly for those channels that had
3760 clients removed from them. Affected file silcd/server.c.
3762 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3764 * Found the reason of random crashes in the server. We weren't
3765 ignoring the SIGPIPE signal (which can be sent in write())
3766 and it crashed the server. Affected file silcd/silcd.c.
3768 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3770 * Assure that sock->user_data is not NULL in the function
3771 silc_server_packet_send in silcd/packet_send.c.
3773 * Disconnect the remote connection if it could not be added
3774 to any ID lists in the server. The affected file is
3777 * Check in silc_server_packet_send[_real/dest] that the
3778 socket is not disconnecting and ignore the data if it is.
3779 Affected file silcd/packet_send.c.
3781 * Define inline to __inline on native WIN32 compilation.
3782 Affected file includes/silcwin32.h.
3784 * Added some explicit type casts for inline code since MSVC
3785 require them. Affected files lib/silcutil/silcbuffer.h,
3786 lib/trq/silcdlist.h and lib/trq/silclist.h.
3788 * Print warning in log files from now on if the packet
3789 decryption fails. Affected file silcd/server.c.
3791 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3793 * Changed the `say' client operation's interface to accept
3794 new `type' argument to indicate the type of the message sent
3795 by the library. The application may filter the library's
3796 messages according the type. The affected file is the
3797 lib/silcclient/silcapi.h.
3799 * Added two new functions to lib/silcclient/silcapi.h:
3800 silc_client_del_client and silc_client_del_client_by_id.
3801 Affected file lib/silcclient/idlist.c.
3803 * Moved the clientincludes.h from includes/ to silc/ and
3804 serverincludes.h from includes/ to silcd/.
3806 * The modes for the CMODE and CUMODE are now passed as
3807 uint32 for application with COMMAND_REPLY. The affected
3808 file is lib/silcclient/command_reply.c.
3810 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3812 * /WHOIS without arguments shows client's own information.
3813 Affected file lib/silcclient/command.c.
3815 * Changed PING to not accept any arguments. The specs
3816 says that client can ping only the connected server so
3817 requiring an argument is not needed. Affected file is
3818 lib/silcclient/command.c.
3820 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3822 * Fixed a fatal bug in private message sending and reception
3823 encryption and decryption when using private message keys.
3824 The implementation was incorrect and did not follow the
3825 specification. It causd that some of the message were
3826 lost since it did not use the sending and receiving keys
3827 as the protocol suggests. This has been fixed and will cause
3828 incompatibilities with older clients when sending private
3829 message encrypted with private message keys. Affected files
3830 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3831 and various other in Irssi SILC Client.
3833 Added `responder' boolean argument to the functions
3834 silc_client_add_private_message_key[_ske] to indicate when
3835 the key is added as responder or initiator of the key
3838 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3840 * Removed the silc_ske_check_version function and created
3841 a SilcSKECheckVersion callback. Added also a function
3842 silc_ske_set_callbacks that is now used to set all SKE
3843 callbacks. The callback functions are not given to
3844 the SKE functions anymore, but this function is used to
3847 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3849 * Added `silc_version' argument to the silc_client_alloc
3850 to define the version of the application for the library.
3851 The library will use the version string to compare it
3852 against the remote host's (usually a server) version
3853 string. Affected file lib/silcclient/silcapi.h
3855 * Added the KE protocol context to Key Agreement context
3856 in client library so that we can abort the SKE if it
3857 is in process when we get timeout. Affected file is
3858 lib/silcclient/client_keyagr.c.
3860 * Do not resolve the client ID forever if it returns in the
3861 first time that such client does not exist. This was done
3862 for example with private message. Affected file is
3863 lib/silcclient/client_prvmsg.c.
3865 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3867 * Do not add regex.h for WIN32. The affected file
3868 includes/silcincludes.h.
3870 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3871 not work yet 100%. It generates the DLL's automatically
3872 when compiling with --with-win32 under cygwin.
3874 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3876 * lib/contrib/regex.c is not compiled on WIN32.
3878 * Added silc_net_get_socket_opt function to the
3879 lib/silcutil/silcnet.h.
3881 * Added includes/silcwin32.h for WIN32 specific includes
3884 * Do not use ptime structure or any of the posix process
3885 functions on WIN32 in lib/silccrypt/silrng.c.
3887 * Added silc_gettimeofday to provide generic function
3888 for struct timeval on all platforms. Added the function
3889 to lib/silcutil/silcutil.h.
3891 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3893 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3894 library as they clearly belong there. As a plus side we
3895 can make the actual socket connection routines platform
3898 Added also new generic function silc_socket_read and
3899 silc_socket_write (that used to be silc_packet_[read/write].
3900 The implementation of these are platform specific.
3902 * Added WIN32 specific routines of silc_socket_[read/write]
3903 to lib/silcutil/win32/silcwin32sockconn.c.
3905 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3907 * Added preliminary support for native WIN32 compilation under
3908 cygwin (using the -mno-cygwin option for GCC) to the
3909 ./configure.in.pre. The --with-win32 now prepares the
3910 compilation for native WIN32.
3912 * Rewrote the SILC Scheduler interface in the file
3913 lib/silcutil/silcschedule.h. The scheduler is now context
3914 based and does not have anymore any global static scheduler.
3915 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3916 and created lib/silcutil/win32 directory for WIN32 based
3919 * Added Unix specific network routines to the
3920 lib/silcutil/unix/silcunixnet.c and the old
3921 lib/silcutil/silcnet.c includes now only generic routines.
3923 Added WIN32 specific network routines to the
3924 lib/silcutil/win32/silcwin32net.c.
3926 * Added Unix specific utility functions from the
3927 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3929 * Added WIN32 SILC Scheduler to the file
3930 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3933 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3935 * Do not handle JOIN notify in the server if the target client
3936 is not registered (idata->registered == FALSE). The affected
3937 file is silcd/packet_receive.c.
3939 * Update the nickrec->founder in event_cumode in the Irssi SILC
3940 client. Affected file irssi/src/silc/core/silc-channels.c.
3942 * Fixed the CUMODE_CHANGE notify handling in the server when
3943 server and router are announcing their clients on channels.
3944 Now the mode changes are saved and notified correctly. The
3945 affected file is /silcd/packet_receive.c.
3947 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3948 They really did not replace the cache entry in the ID Cache.
3949 Now they do that. Affected file silcd/idlist.c.
3951 * Fixed the KICK notify handling in the Irssi SILC client to
3952 update the channel records so that the kicked client does not
3953 appear to be on the channel. The affected file is
3954 irssi/src/silc/core/silc-channels.c.
3956 * Always update the conn->current_channel when executing command
3957 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3959 * Fixed the KILL notify handling in Irssi SILC client to remove
3960 the killed client on all channels.
3962 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Fixed the silc_parse_command_line to remove extra spaces
3965 from the start and end of the arguments. Affected file is
3966 lib/silcutil/silcutil.c.
3968 * Cancel and free any active protocol in the function
3969 silc_server_close_connection. Affected file silcd/server.c.
3971 * Cancel and free any active protocol in the function
3972 silc_client_close_connction. Affected file is
3973 lib/silcclient/client.c.
3975 * Do not execute the KILL command for clients that are in
3976 history (ie. they are not in the network). Affected file is
3979 * Fixed KILL notify handling, client does not crash anymore.
3980 Affected file irssi/src/silc/core/silc-channels.c.
3982 * Reduced the default packet buffer size from 2048 to 1024 in
3983 lib/silccore/silcpacket.c.
3985 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3986 counter to the SKE context that is incresed when the SKE library
3987 performs async operation outside the library. If the outside
3988 process frees the SKE context and FREED status will be set
3989 and the library will detect after the sync operation that the
3990 libary is freed. The affected files are
3991 lib/silcske/silcske[_status].[ch].
3993 * Resolve the client entry information in the function
3994 silc_client_channel_message to assure that NULL pointer is not
3995 passed as client entry to the application. */
3997 * Fixed the task timeout calculation to assure that there is
3998 never negative timeouts. The affected file is
3999 lib/silcutil/silcschedule.c.
4001 * Fixed the channel user mode notification sending in server.
4002 It was sent point-to-point to the router (or to server by router)
4003 but it needs to be destined to a channel. The routines now
4004 supports sending the channel user mode notifys to the channels
4005 when announcing clients and channels. Affected files are
4006 silcd/server.c and silcd/packet_receive.c.
4008 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4009 It did not actually replace the old channel entry in the cache.
4010 Affected file lib/silcclient/client_notify.c.
4012 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Fixed a possible crash in silc_packet_send_prepare. It now
4015 assures always that there is enough space in the buffer and
4016 at the tail area of the buffer (for MAC).
4018 Fixed the inbound buffer reallocation in silc_packet_read.
4019 It was old code and did not handle the reallocation correctly.
4022 The affected file is lib/silccore/silcpacket.c.
4024 * Fixed buffer overflow in silc_parse_nickname in the file
4025 lib/silcutil/silcutil.c.
4027 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * make install generates new server keys only if there is not
4032 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4035 Added check that if the NOREPLY is set then we will not send
4036 the away message. This avoids infinite loop of away messages
4037 if both clients are away. The affected file is
4038 lib/silcclient/client_prvmsg.c.
4040 * Fixed client crash if /NICK was given without arguments.
4041 Affected file lib/silcclient/command.c.
4043 * Server does not send the invite list in INVITE command back
4044 to the client if the list was not altered. Added this notion
4045 to the protocol spec as well. Affected file silcd/command.c.
4047 Fixed possible crash in INVITE command by checking the
4048 value of silc_server_get_client_route command.
4050 * Fixed the INVITE notify type handling. The arguments are now
4051 taken in correct order and client does not crash. The affected
4052 file is irssi/src/silc/core/silc-channels.c.
4054 Removed the "Inviting xxx to channel" message from the
4055 client library away and let the application handle it.
4056 Affected file lib/silcclient/command.c. Added that message
4057 to Irssi SILC client's message formats.
4059 * Fixed CMODE command crash in client. It now checks the
4060 amount of arguments correctly and does not crash. The affected
4061 file is lib/silcclient/command.c.
4063 * Do not create new channel automatically in silc_channels_join
4064 but check whether the channel by that name already exists.
4065 Affected file irssi/silc/core/silc-channels.c.
4067 * Do not send the SERVER_SIGNOFF to router if the disconnected
4068 entity was the router. Affected file silcd/server.c.
4070 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4071 SILC client as it was missing from there.
4073 Added the handling of the KICK notify to the Irssi SILC client
4074 as it was missing. Added "you have been kicked" message to
4075 Irssi SILC client's message modules formats.
4077 Added the handing of the KILL notify to the Irssi SILC client
4078 as it was missing. Added the kill message module formats
4081 The affected file is irssi/src/silc/core/silc-channels.c.
4083 * The router did not save the channel mode the server announced.
4084 Affected file silcd/packet_receive.c.
4086 * Fixed a possible crash in INFO command in server. If the
4087 server did not provide the server info it crashed. Affected
4088 file silcd/command.c.
4090 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * Fixed the GETKEY command in the server to check also the
4093 global list. Otherwise the GETKEY would not work correctly
4094 in normal SILC server. Affected file silcd/command.c.
4096 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * Fixed GETKEY crash, it crashed if the command did not succseed.
4100 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4102 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4103 is now real and not just an macro interface to GMP.
4105 Removed the entire GMP from the source tree and imported new
4106 NSS MPI library instead. Reason for removing GMP is that it is
4107 extremely large and compiles extremely slow. The NSS MPI
4108 is only a few files and compiles in less than 10 seconds.
4109 The speed is also about the same as GMP. The MPI is imported
4110 to lib/silcmath/mpi.
4112 If the system has GMP installed we will still use the GMP.
4113 If it is not then the NSS MPI will be compiled.
4115 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4117 * Merged a long nickname (127 characters long) crash bugfix from
4118 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4120 * Merged a freed memory reference bugfix from Irssi CVS tree.
4121 Affected file irssi/src/core/commands.c.
4123 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4125 * Added the server's public key sving and verification to the
4126 server when performing the SKE. This was missing and the
4127 remote server's (or router's) public key was accepted without
4128 checking whether we have it previously or trust it at all.
4129 Affected file silcd/protocol.c.
4131 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Check in the silc_server_timeout_remote if protocol is active
4134 and make sure that the protocol's final callback is called so
4135 that all memory if freed. Affected file silcd/server.c.
4137 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4139 * silc_server_whois_send_reply crashed the server if the nickname
4140 was 127 characters long. Affected file silcd/command.c.
4142 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4144 * Added sanity check to the silc_server_new_client. If the hostname
4145 is provided inside username then check that the provided hostname
4146 really is the same as the resolved one. If the hostname was not
4147 resolved then check it from the public key. Affected file is
4148 silcd/packet_receive.c.
4150 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4151 if the server disconnected us and the connection is not valid
4152 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4154 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4155 the library to the lib/silcutil/silcutil.[ch].
4157 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Close log file after open. Affected file
4160 lib/silcutil/silclog.c.
4162 * Check whether sock == NULL in silc_client_send_packet and return
4163 if it is. Affected file lib/silcclient/silcclient.c.
4165 * Check rec->entry == NULL in the Irssi SILC Client before
4166 sending the channel message. Affecte file is
4167 irssi/src/silc/core/silc-servers.c.
4169 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Merged a splitted window bugfix from Irssi CVS tree. The
4172 affected file is irssi/src/fe-text/textbuffer-view.c.
4174 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4175 It did not print nickname.
4177 * Improved the distributions system a bit.
4179 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4182 irssi/src/fe-text/gui-window.c.
4184 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4185 to in-active server. The affected file is
4186 irssi/src/silc/core/client_ops.c.
4188 * Resolve the client in USERS command reply if the entry does
4189 not have username resolved. The affected file is
4190 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4191 command to WHOIS command to really resolve stuff. The USERS
4192 is not used any more in any critical section so WHOIS can
4193 be used even though it might be slower than IDENTIFY.
4195 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4198 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Changed the protocol API a bit more consistent in the
4201 lib/silccore/silcprotocol.[ch].
4203 * Changed the following headers to ROBODoc format:
4205 lib/silccore/silcpayload.h
4206 lib/silccore/silcprotocol.h
4207 lib/silccore/silcsockconn.h
4209 All core library headers are now formatted.
4211 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Fixed a bug in Irssi SILC client; do not show that you are
4214 server/router operator if you really are not. Affected file is
4215 irssi/src/silc/core/client_ops.c.
4217 * Renamed silc_command_free_payload to silc_command_payload_free.
4218 Affected file lib/silccore/silccommand.h
4220 * Added silcmath.h to include the prototoypes of various routines
4221 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4224 * Changed the following headers to ROBODoc format:
4226 lib/silccore/silcchannel.h
4227 lib/silccore/silccommand.h
4228 lib/silccore/silcid.h
4229 lib/silccore/silcidcache.h
4230 lib/silccore/silcmode.h
4231 lib/silccore/silcnotify.h
4232 lib/silccore/silcpacket.h
4233 lib/silcmath/silcmath.h
4235 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Added checking to the server code not to start the server if
4238 ciphers and stuff are not configured properly. Affected files
4239 silcd/serverconfig.[h] and silcd/server.c.
4241 * Changed the layout of the header files of the public interfaces
4242 in the SILC libraries. The new layout supports ROBODoc
4243 documentation tool (and some others) so that it is easy to create
4244 a library reference manual. All the other headers and source
4245 code must still follow the CodingStyle document. Also source
4246 code must not include these ROBODoc stuffs, only the headers.
4247 Furthermore, all public interface headers must now be named
4248 by using `silc' prefix, example: silcapi.h, silccipher.h.
4249 Some files were renamed due to this. All the other headers
4250 must not be used as public interfaces. I will update the
4251 CodingStyle document later. Changed following headers, so far:
4253 lib/silcclient/silcapi.h
4254 lib/silccore/silcauth.h
4255 lib/silccore/silcprivate.h
4256 lib/silccrypt/silcdh.h
4258 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Removed silc_client_packet_send_flush from the client library
4263 as it is not needed. Affected file lib/silcclient/client.[ch].
4265 * Added printing of message of unresolved authentication method
4266 to the Irssi SILC client. Added it to the module formats.
4267 Removed the same message from the client library.
4269 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Added new distribution feature, DISTLABEL. Every distribution
4272 can define own preprocessor label that can be used in the
4273 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4274 file distributions, acconfig.h.pre and prepare.
4276 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Added Makefile.defines_int to include the actual definitions
4279 for Makefile.defines.in. Tested the new distribution system,
4280 created distributions and tested installation.
4282 * Added AWAY message printing to the Irssi SILC client. Added
4283 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4285 * Added SCONNECT command to call the SILC's CONNECT command.
4286 Cannot use CONNECT directly since Irssi uses that internally.
4287 Affected file irssi/src/silc/core/silc-servers.c.
4289 Added ACTION local command. It is same as ME command but takes
4290 the channel as mandatory argument.
4292 Rewrote some of the Irssi's help files to suite for SILC
4295 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4297 * Added Makefile.defines[.in] that should for now on be included
4298 in all Makefile.am file in the source tree. That file includes
4299 all common compilation definitions for SILC source tree.
4301 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Minor changes to the ./prepare script to change the package
4304 name according the distribution name to the configure.in.
4306 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Created new distribution system. Added file `distributions'
4309 that defines all the distributions that can be created out of
4310 the SILC source tree. The ./prepare script now reads that
4311 file to determine how to prepare the distributions. The
4312 first argument to the ./prepare is the name of the distribution
4313 and second is the version of the distribution. If given
4314 without arguments it creates the default (toolkit) distribution
4315 with the default version (defined in ./prepare).
4317 All Makefile.am files that are subject to the distributions
4318 are now named as Makefile.am.pre. These are ./Makefile.am
4319 and lib/Makefile.am. Others may be changed later.
4321 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4323 * Added invite list, ban list, some key management and connection
4324 error message printing to module formats in the Irssi SILC client.
4326 * Added new silc_client_set_away_message to set the away message
4327 that is back to the person who sent private message. The
4328 affected file lib/silcclient/silcapi.h and the
4329 lib/silcclient/client_prvmsg.c.
4331 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Fixed the private message sending in the Irssi SILC client,
4334 added local command KEY to the Irssi SILC client.
4336 Added key management and key agreement message formats to the
4337 irssi/src/fe-common/silc/module-formats.[ch].
4339 Added USERS (alias WHO) printing, server/router operator
4340 indication and LIST command printing to the module formats.
4342 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4344 * Fixed channel joining notify handling, cumode notify handling
4345 from Irssi SILC client.
4347 * Added SILC specific module-formats to the Irssi SILC client so
4348 that SILC specific message hilighting, colors etc is possible.
4349 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4351 Added channel mode, channel user mode, actions, notices,
4352 whois and whowas printing to the the module-formats.c.
4354 * Fixed a bug in channel deletion in the server. The channel
4355 is not left to the cache even if the channel founder auth mode
4356 is set when there are no users anymore on the channel. Affected
4357 file silcd/server.c.
4359 * The silc_net_localhost now resolves the entire hostname including
4360 the domain name. Affected file lib/silcutil/silcnet.c.
4362 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * Changed the ask_passphrase client operation to be ascynchronous.
4365 It has now a completion callback and a context that the
4366 application must call after it has got the passphrase from
4367 the user. Affected files lib/silcclient/silcapi.h,
4368 lib/silcclient/protocol.c, lib/silcclient/command.c and
4371 Added SilcAskPassphrase callback that the application calls
4372 to deliver the passphrase to the library.
4374 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4375 The public key verification and especially a certificate
4376 verification is asynchronous procedure.
4378 Added new SILC_SKE_STATUS_PENDING status to indicate the
4379 request is pending and a callback will be called to finalize
4382 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4383 indicate that remote end did not send its public key (or
4384 certificate), even though we require it. Added check for this
4385 condition in the SKE. This was a security bug, now fixed.
4387 Defined new SilcSKEVerifyCbCompletion callback that is called
4388 when the verification process is completed.
4390 The affected files lib/silcske/silcske_status.h and
4391 lib/silcske/silcske.[ch].
4393 * Changed the verify_public_key client operation to be async
4394 as well. Defined SilcVerifyPublicKey callback that is used to
4395 indicate the success of the public key verification process.
4397 Changed the server and client to use the new async client
4400 * Changed the Irssi SILC client's internal scheduler to be called
4401 twice as many times as it used to be. As a result the client
4402 should be a bit faster now. Affected file is
4403 irssi/src/silc/core/silc-core.c.
4405 * Added support to Irssi SILC client of asynchronous public key
4406 verification and passphrase inquiry. Affected file is
4407 irssi/src/silc/core/silc-core.c.
4409 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4411 * Do not say "You have left channel %s" in client library.
4412 Moved it to the application. Affected files are
4413 lib/silcclient/command.c and silc/client_ops.c.
4415 * Fixed silc_client_get_clients. Command context was not
4416 duplicated and was freed memory in the callback. Affected
4417 file lib/silcclient/idlist.c.
4419 * Do not say "you are now talking..." on JOIN command in the
4420 client library. The appliation must handle it.
4422 * Do not say ".. changed topic to" in command reply in the
4423 client libary. The application must handle it.
4425 * Fixed TOPIC command sending in the client library.
4427 * Fixed a memory leak in silc_client_command_free in the file
4428 lib/silcclient/command.c.
4430 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Imported a modified version of Irssi client to the source tree.
4433 The Irssi will be used to create a new client called
4434 Irssi SILC. Imported to irssi/.
4436 Added silc_core_init_finish function to the Irssi. Affected
4437 file irssi/configure.in.
4439 A lot changes in the Makefile.ams around the irssi tree.
4441 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Do not rehash if the new size is same as the old size of the
4444 hash table, in the silc_hash_table_rehash*. The affected file
4445 lib/silcutil/silchashtable.c.
4447 * Replaced hash_table_del_by_context calls from the server
4448 (when channel->user_list and client->channels) to the
4449 hash_table_del as it is sufficient and faster.
4451 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Added silc_hash_table_list, silc_hash_table_get and the
4454 SilcHashTableList structure to provide an alternative way to
4455 traverse the hash table. The affected files are
4456 lib/silcutil/silchashtable.[ch].
4458 * Changed the server's idlist routines to use the hash table
4459 routines to optimize the code.
4461 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Replaced the client entry's `channel' list and channel entry's
4464 `user_list' list to hash tables for optimized lookup. Changed
4465 the code to use the hash table interface around the code.
4466 Affected file lib/silcd/idlist.[ch].
4468 * Added `auto_rehash' boolean argument to the function
4469 silc_hash_table_alloc to indicate whether the hash table should
4470 auto-rehash when it thinks is appropriate time. It will
4471 increase the hash table size if the there is twice as much
4472 entries in the table than the size of the table, and will
4473 decrease the size if there are twice as less entries than
4474 the size of the table.
4476 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4480 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * silc_idcache_purge_by_context deletes the entry now by context
4483 as it is supposed to do. Affected file lib/silccore/idcache.c.
4485 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4486 client is not anymore valid (WHOWAS givens the info) and not
4487 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4489 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4491 * Removed the `data' and `data_len' arguments from the ID Cache
4492 interfaces and added `name' argument. ID Cache does not handle
4493 anymore the binary data only a names associated with given ID.
4495 * When hashing a Client ID with silc_hash_id the entire ID is
4496 not hashed anymore, instead only the hash of the Client ID is
4497 hashed. This way we can access the Client ID from the cache
4498 with Client ID but with the hash of the ID (which is a hash of
4499 the nickname) as well without any difference in performance.
4501 Added also silc_idcache_find_by_id_one_ext to do one on one
4502 searching when we have the actual ID. Added also function
4503 silc_hash_client_id_compare. The affected files are
4504 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4506 * When hashing the name associated with a ID it is always done
4507 in lowercase. This way we can access the cache without worrying
4508 about case-sensitivity, even though, for example nicknames are
4511 * Fixed a bug in server with channel message sending. It put
4512 wrong ID type as destination ID. The affected file
4513 silcd/packet_send.c.
4515 * silc_idcache_del_by_context now deletes from all hash tables
4516 by context. Affected file lib/silccore/idcache.c.
4518 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Changed the client library to use the new ID Cache interface.
4521 Changes around the source tree.
4523 * Added silc_hash_table_rehash_ext to rehash with specific
4524 hash function. Affected file lib/silcutil/silchashtable.[ch].
4526 * Added silc_hash_string_compare to compare two strings in the
4527 hash table. Affected file lib/silcutil/silcutil.[ch].
4529 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Added new function silc_idcache_del_by_context into the
4532 lib/silccore/idcache.[ch].
4534 * Changed the server's ID list routines to use the new ID Cache
4535 interface. Changes around the source tree.
4537 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Added silc_hash_table_del[_by_context]_ext functions in to the
4540 lib/silcutil/silchashtable.[ch].
4542 Removed silc_hash_table_find_all* routines and added new
4543 silc_hash_table_find_foreach to replace them.
4545 Added silc_hash_table_replace_ext function as extended
4546 replacing function. Separated the simple hash table interface
4547 from the extended hash table interface in the file
4548 lib/silcutil/silchashtable.h.
4550 * Fixed minor bugs and changed it to use some of the new
4551 hash table functions in lib/silccore/idcache.c
4553 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Added new function silc_hash_table_find_all to return all keys
4556 in the hash table by the specified key. As the hash table is
4557 collision resistant it also makes it possible to have several
4558 duplicate keys in the hash table. This function may be used to
4559 find all of the keys from the hash.
4561 Added user_context arguments to the SilcHashFunction,
4562 SilcHashCompare and SilcHashDestructor to deliver user specified
4565 Added new fuctions silc_hash_table_find[_all]_ext to do
4566 extended lookup with specified hash and compare functions and
4567 specified user contexts.
4569 Added new function silc_hash_table_add_ext to add the key
4570 with specified hash function and user context.
4572 Added new function silc_hash_table_foreach to traverse all
4573 entrys in the hash table. Added SilcHashForeach callback
4576 Added new function silc_hash_table_del_by_context to delete
4577 the entry only if the context associated with the key matches.
4579 Affected files are lib/silcutil/silchashtable.[ch].
4581 * Removed silc_hash_[server/client/channel]_id and added just
4582 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4583 silc_hash_id_compare to compare two ID's using as the hash table
4584 comparison function. Added also silc_hash_data to hash
4585 binary data and silc_hash_data_compare to compare it.
4587 * Removed silc_idlist_find_client_by_hash as it is not needed
4588 anymore. Affected file silcd/idlist.[ch].
4590 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4591 to use internally the SilcHashTable. The new ID Cache is a lot
4592 faster than the old one. Some of the ID Cache interface was also
4593 rewritten and obsolete and stupid functions were removed.
4595 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Added entry_count field to the SilcHashTable to keep the number
4598 of the entries in the table. Implemented the function
4599 silc_hash_table_rehash. Added new function
4600 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4602 Fixed a minor bug in silc_hash_table_free.
4604 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4605 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4606 into the lib/silcutil/silcutil.[ch].
4608 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Implemented a collision resistant hash table into the
4611 lib/silcutil/silchashtable[ch]. See the header and the source
4612 for the SilcHashTable API.
4614 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Merged dotconf version 1.0.2 into lib/dotconf.
4618 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Do not compile anything in lib/silcsim/* if the SIM support
4621 is not enabled. The tree should now compile without problems
4624 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4626 * Compiled the SILC under cygwin. Compiled and tested briefly
4627 without problems. More tests needed. The SIMs didn't compile
4630 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4632 * Fixed possible crash in silc_get_username in the
4633 lib/silcutil/silcutil.c.
4635 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Fixed a va_arg in silc/client_ops.c.
4639 * Oops, RC5 routines were named AES and caused some problems
4640 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4642 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4644 * Added new SilcIDIP structure into the lib/silccore/id.h and
4645 replaced the old `ip' fields from all SILC ID's to that type.
4646 This is a step towards IPv6 support.
4648 The silc_id_get_len takes now the ID as an extra argument.
4649 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4650 both IPv4 and IPv6 based ID's.
4652 The affected files are lib/silccore/id.[ch] and other files
4653 around the tree using these routines.
4655 * Removed the ID length arguments in server from various
4656 silc_server_send_notify_* routines -> they are not needed
4659 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Fixed memory leak in silc_encode_pem_file in the file
4662 lib/silcutil/silcutil.c.
4664 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * Check minor version as well in the SKE. Affected files are
4667 silcd/protocol.c and lib/silcclient/protocol.c.
4669 * Added --identifier option to the server so that an identifier
4670 can be when creating the public key for the server. Affected
4671 file is silcd/silcd.c.
4673 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4674 lib/silccrypt/silcpkcs.c.
4676 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4678 * Register default ciphers and stuff when using -C option with
4679 the server. Affected file sildc/silcd.c.
4681 * Put back the servers public key filename format, it is better
4682 than the new one. For now, the client keys are saved with the
4683 new filename format. The affected file silc/client_ops.c.
4685 * Implemented the Cipher API for the rest of the ciphers that
4686 did not implement it or implemented it the wrong way.
4688 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Register default ciphers and stuff when using the -S option
4691 in the client. Affected file silc/silc.c. Same also when
4692 creating new key pair with -C option.
4694 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Fixed the silc_verify_public_key client operation function to
4697 save the public keys differently. The fingerprint is now
4698 used as filename and not the hostname. This way also the
4699 client keys are saved uniquely and not with hostnames. The
4700 affected file is silc/client_ops.c.
4702 * Trimmed the silc_hash_fingerprint function to remove extra
4703 whitespaces from the end of the fingerprint. The affected
4704 file is lib/silccrypt/silchash.c.
4708 * Added silc_cipher_register_default function to register all
4709 default ciphers. It can be used when configuration files
4710 does not exist and the application does not want any specific
4711 ciphers in any specific order.
4713 The SilcDList is now used as silc_cipher_list dynamically
4714 allocated cipher list. Removed the static list all together
4715 and now all ciphers must be allocated to the dynamic list.
4716 The silc_cipher_alloc routine was changed to check only the
4719 All silc_cipher_* routines that used to return int returns
4722 The affected files lib/silccrypt/silccrypt.[ch].
4724 * The same thing was done to silc_hash_* as for silc_cipher_*
4725 routines. Affected files lib/silccrypt/silchash.[ch].
4727 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4728 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4729 Added also silc_pkcs_[un]register[_default] functions.
4730 Removed the data_context from the PKCS API.
4732 * Added silc_hmac_register_default function to register default
4733 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4734 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4735 to unregister all hmacs at once.
4737 * Register the default ciphers, hash functions, PKCSs and HMACs
4738 if client's configuration file does not exist. The affected
4741 * The client did not load the hash functions from the SIM
4742 modules at all. Added support for this. Affected file is
4743 silc/clientconfig.c.
4745 * When decoding public key with silc_pkcs_public_key_decode, check
4746 the supported algorithm only if PKCS are registered. Affected
4747 file lib/silccrypt/silcpkcs.c. The same was done with the
4748 silc_pkcs_private_key_decode.
4750 * Fixed the SILC List routines to keep the list always in order.
4751 It used to change the list's order when traversing the list but
4752 not it preserves the order. Affected file lib/trq/silclist.h.
4754 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Added the client library to use the SilcSocketConnection's
4757 reference counter (by silc_socket_dup) to prevent the bug that
4758 the socket object may be freed underneath async operation.
4760 * The name resolv library checking fixes in the configure.in.pre.
4763 * Created new version of the protocol drafts for future
4764 development. The -03 drafts are the ones that will be changed
4765 in the trunk now and the -02 will remain as they are.
4767 * Send list of CUMODE notifys to the router when announcing
4768 the channel users to the router. Affected file silcd/server.c.
4769 If the router receiving channel founder CUMODE for a channel
4770 that already has channel founder it will send CUMODE notify
4771 to the sender to remove the channel founder rights from the
4772 announced client. Affected file silcd/packet_receive.c.
4774 * The CUMODE notify may now use Server ID as well as the entity
4775 who changes the mode. Updated protocool specs.
4777 * Updated INSTALL and README files.
4779 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * New web pages in the http://silc.pspt.fi. The pages was
4786 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * Implemented the [DenyConnectin] config section in the server.
4789 Added silc_server_config_denied_conn to check whether incoming
4790 connection is denied. Affected file silcd/serverconfig.[ch].
4792 * Do not check the ports when checking the incoming configuration
4793 data if the port is 0, meaning any. Affected file is
4794 silcd/serverconfig.c.
4796 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * Fixed buffer overflow in silc_string_compare in the file
4799 lib/silcutil/silcutil.c.
4801 * Fixed double free in silc_server_command_leave in the file
4804 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Fixed the version checking in the server. Affected file is
4809 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Fixed the configuration data fetching when accepting new
4812 connections in the server. Affected file silcd/server.c.
4814 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Added `sender_entry' argument to the function
4817 silc_server_packet_relay_to_channel so that we can check
4818 whether some destination actually belongs to the same route
4819 the sender belongs (ie, we must not resend the packet to the
4820 sender). Affected file silcd/packet_send.[ch].
4822 * Added `servername' field to the SilcClientEntry in the server
4823 to hold the name of the server where client is from. Affected
4824 file is silcd/idlist.h.
4826 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Moved the channel message encrypting in the router betwen
4829 router connections from silc_server_channel_message to the
4830 silc_server_packet_relay_to_channel since we want to check
4831 whether we have anybody channel before encrypting anything.
4832 Affected files silcd/packet_[receive/send].c.
4834 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Fixed the [AdminConnection] server config section to support
4837 multiple entries. Affected file silcd/serverconfig.c.
4839 * Added support into the server to check the validity of the
4840 incoming connection before executing any KE or authentication
4843 * The connection configuration is now saved to the KE and
4844 connection auth protocol contexts and not fetched anymore in
4845 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4847 * The local hosts listenning address and port is also resolved
4848 now when starting the server. We want to have the socket object
4849 to include the real address and port for the listener. Added
4850 new function silc_net_check_local_by_sock into the files
4851 lib/silcutil/silcnet.[ch].
4853 * Fixed a broadcast bug in server -> do not broadcast if we
4856 * Fixed a routing bug. Do not route broadcast packets ever.
4857 Broadcast packets must be processed always and not routed since
4858 they may be destined to some other host than yourself and thus
4859 would get routed without no good reason. Affected file is
4862 * Added function silc_server_config_is_primary_route to check
4863 whether primary router connection has been configured (a router
4864 configuration that we are initiating). If there is not, we
4865 will assume that there is only two routers in the SILC network
4866 and we will use the incoming router connection as our primary
4867 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4869 * Changed the order of the broadcasting. Broadcast _after_ the
4870 packet has been processed not before. Affected file is
4873 * Fixed a [ClientConnection] parsing bug. The port was never
4874 parsed correctly thus resulting to port 0. Affected file
4875 silcd/serverconfig.c.
4877 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4878 argument and did not set the broadcast packet flag. Affected
4879 file silcd/packet_send.c. Fixed same bug in the function
4880 silc_server_send_notify as well.
4882 * If we receive NEW_ID packet for our own ID in the server, ignore
4885 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Removed the nickname from the Private Message Payload.
4890 Updated the code and the protocol specs.
4892 * Updated protocol specs for submitting to the IETF.
4894 * Tweaked the Random Number Generator a bit. Affected file
4895 lib/silccrypt/silcrng.c. Exported a new function
4896 silc_rng_[global]_add_noise which can be used to add more
4899 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4901 * Do not parse packets with different timeout when protocol
4902 is active -> may cause problem with rekey. Affected file
4905 * When server receives signoff notify it must not create
4906 new channel key if the client is on any channels since the
4907 sender of the signoff notify will create it.
4909 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Added printing of error messages during SKE protocol from the
4912 failure packet sent by server during SKE. Affected file
4915 * Removed the client's failure_callback handling with timeout
4916 and handle it immediately when received.
4918 * The SKE library returned wrong type in SUCCESS and FAILURE
4919 packets. They must be 32 bit MSB not 16 bit MSB.
4921 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Ok, rewrote the logic of the re-key and now it seems to work.
4924 I tested it on high traffic with frequent re-keys without
4925 problems. Added hmac_receive (and renamed hmac to hmac_send)
4926 in SilcClientConnection in lib/silcclient/client.h and
4927 in SilcIDListData in silcd/idlist.h. Also, removed the
4928 SilcPacketParserContext's cipher and hmac fields as they are
4929 not needed anymore and actually caused some problems when
4930 the ciphers and hmac's changed underneath the packet parser.
4932 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * If re-key protocol is active then process the incoming packets
4935 synchronously since we must assure that icoming packets encrypted
4936 with the old key is processed before the new keys is set to
4937 use. This is true other packets than for REKEY packets.
4938 Affected file silcd/server.c. The same was done to client library
4939 as well, affected file lib/silcclient/client.c.
4941 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Fixed bug in client and server to accept the force send if
4944 the packet is send from silc_[server/client]_packet_process
4945 function. Otherwise the packets are never delivered, oops.
4947 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Disable force sending of packets when REKEY protocol is active.
4950 We must assure that no packet is sent directly when rekey is
4951 performed. All packets must be sent through packet queue.
4952 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4953 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4954 function is silc_[server/client]_packet_send_real to check
4957 * Replaced the SIM paths from example config files to
4958 /usr/local/modules. Also, make install creates now
4959 /usr/local/silc/logs directory to hold all the SILC server
4962 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Made the configure.in.pre work on Solaris. Patch by salo.
4966 * Made all ciphers compatible with non-x86 machines. Defined
4967 CBC mode macros into lib/silccrypt/ciphers_def.h.
4969 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Fixed the make install.
4973 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * When MAC computation fails the silc_packet_decrypt returned 0
4976 even though it was supposed to return -1. Fixed this. The
4977 affected file is lib/silccore/silcpacket.c.
4979 * Do not replace the config files in /etc/silc (in make install)
4980 if they already exist. Affected file ./Makefile.am.
4982 * Do not send re-key packets immediately but through packet queue.
4983 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4985 * Changed silc_net_check_host_by_sock to return FALSE if the
4986 IP/DNS could not be resolved. Though, it returns the IP address
4987 now even if it could not resolve it (but returns also FALSE).
4988 Affected file lib/silcutil/silcnet.[ch].
4990 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Added silc_pkcs_decode_identifier to decode the public key's
4993 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4994 Added also silc_pkcs_free_identifier. Added also new context
4995 SilcPublicKeyIdentifier.
4997 * Added -S option to the silc client. It is used to dump the
4998 contents of the specified public key file.
5000 * Changed the PKCS api to return the public key length when
5001 setting the public key.
5003 * Fixed a fatal bug in the public and private key file loading.
5004 Affected file lib/silccrypt/silcpkcs.c.
5006 * Execute the packet parsing for client with zero (0) timeout
5007 if the protocol is active. Affected file silcd/server.c.
5009 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Made the key generation options to the silcd program. Added
5012 -C option, equivalent to client's option.
5014 * Added new [ServerKeys] config section to the server. It
5015 configures the server's public and private key.
5017 * Defined generic Public Key Payload into the protocol
5018 specification to send specific type of public keys and
5021 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5022 public key or certificate.
5024 * Implemented the GETKEY command to the server and to the
5025 client library and on user interface.
5027 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Made preliminary `make install' work.
5031 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Added SilcServerRekey context into silcd/idlist.h.
5035 * Added the PFS support as defined in the specification to the
5036 SKE protocol. Affected files lib/silcske/*.c.
5038 * Added `ske_group' field to the SilcServerRekey context to hold
5039 the number of the SKE group that is used with PFS in re-key.
5040 Affected file silcd/idlist.h.
5042 * Added PFS re-key support to the server. Affected file is
5045 * Added silc_protocol_cancel to cancel execution of the next
5046 state of the protocol. Affected file is
5047 lib/silccore/silcprotocol.[ch].
5049 * Added the re-key support with and without PFS to the client
5050 library. Re-key is performed once in an hour, by default.
5052 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5053 Added silc_client_rekey_callback and silc_client_rekey_final.
5054 Affected files are lib/silcclient/protocol.[ch] and
5055 lib/silcclient/client.[ch].
5057 * Removed the `hmac_key' and `hmac_key_len' fields from the
5058 SilcClientConnection structure; not needed. Affected file is
5059 lib/silcclient/client.h.
5063 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Do not ask whether user wants to use the negotiated private key
5066 for private messages, just use it. Affected file is
5067 silc/local_command.c.
5069 * Added `send_enc_key' and `enc_key_len' fields to the
5070 SilcIDListData structure since they are needed in the re-key
5071 phase. Affected file is silcd/idlist.[ch].
5073 * Implemented the simple re-key protocol into the server.
5074 Affected files silcd/server.c and silcd/protocol.[ch]. The
5075 re-key will be performed once in an hour, by default.
5077 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5078 Added silc_server_rekey, silc_server_rekey_callback and
5079 silc_server_rekey_final.
5081 * Removed Tunneled flag from the protocol. Updated the code
5082 and the specifications.
5084 * Adde `pfs' field to the SilcIDListData to indicate whether
5085 the PFS is to be performed in the re-key. Affected file is
5088 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5091 int64 of at least the xintXX size. If void * is less that 4
5092 bytes uint32 * will be used. Defined bool as boolean.
5094 * Changed _ALL_ unsigned long and unsigned int to uint32,
5095 unsgined short to uint16 in the source tree.
5097 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5098 not handle clients that has entry->data.registered == FALSE.
5099 They are not in the network anymore. Affected file is
5102 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Implemented the sending of the SERVER_SIGNOFF notify in the
5105 server. Affected file is silcd/server.c.
5107 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5108 Added also silc_notify_payload_encode_args into the
5109 lib/silccore/silcnotify.[ch].
5111 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5112 Affected file silcd/packet_receive.c.
5114 * Implemented the SERVER_SIGNOFF notify handling in the client
5115 library. Affected file lib/silcclient/client_notify.c. Also,
5116 implemnted the printing of the SERVER_SIGNOFF info to the
5117 application. Affected file silc/client_ops.c.
5119 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5120 if the deleting was successful. Affected file silcd/idlist.[ch].
5122 * Added support for public key authentication in the connection
5123 authentication protocol in the client library. Affected file
5124 lib/silcclient/protocol.c.
5126 * Changed the server's silc_idlist_get_clients_by_* interface
5127 to support already allocated array so that new entries may be
5128 added to pre-allocated array. Affected file silcd/idlist.[ch].
5129 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5130 and command replies.
5132 * All command reply functions in the server now calls the
5133 pending command callback even if error occured. This way the
5134 error will be delivered to the client as well. Affected files
5135 silcd/command.c and silcd/command_reply.c.
5137 * Fixed INFO command to return local server's info if no server
5138 was provided. Affected file lib/silcclient/command.c.
5140 * Removed RESTART command for good. Updated the code and the
5143 * Rewrote parts of the task system. It is a bit simpler now.
5144 Removed unsued task priorities. The affected files are
5145 lib/silcutil/silctask.[ch].
5147 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Moved the USERS printing from the library to the application.
5150 Affected files lib/silcclient/command.c and silc/client_ops.c.
5152 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5156 * Added channel key re-key support. The re-key is perfomed
5157 only by the router and is done once in an hour. Added `rekey'
5158 field to the SilcChannelEntry in the server. Affected files
5159 silcd/server.c and silcd/idlist.h.
5161 * Added silc_task_unregister_by_context into the file
5162 lib/silcutil/silctask.[ch].
5164 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Added SILC_UMODE_GONE mode to indicate when the client is not
5167 present in the SILC network. Added also support to the local
5168 command AWAY that will set this mode. Added support of showing
5169 "xxx is gone" in WHOIS command. The USERS command shows the
5170 gone status as well.
5172 * Fixed setting server and router operator privileges in the
5173 server's UMODE command. Affected file silcd/command.c.
5175 * Merged the SKE KE1 and KE2 payloads into one payload. The
5176 new KE payload is equivalent to the old KE2 payload.
5178 Cleaned up the SKE Start Payload parsing. It now uses the
5179 simple buffer unformatting to do the parsing. A lot faster
5182 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5183 to the SKE that is used to indicate whether both of the SKE
5184 parties should perform authentication. By default only the
5185 responder performs authentication. By setting this flag also
5186 the initiator must do authentication. By default it is unset
5187 since in normal SKE case, client to server connection, only
5188 the responder should do authentication. When doing SKE between
5189 two clients both should perform authentication. Updated the
5190 code and the protocol specs.
5192 * A little fix to IDENTIFY command in the server. Search the
5193 client first by hash not nickname. Affected file is
5196 * Fixed the silc_client_close_connection to support closing
5197 the client to client connections wihtout deleting too much
5198 data. Affected file lib/silcclient/client.c.
5200 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5201 are received if protocol used to be active but is not anymore
5202 the application would crash due to NULL pointer dereference.
5203 Affected files silcd/server.c and lib/silcclient/client.c.
5205 * Added `hash' field to the SilcClientConnection to include
5206 the hash function negotiated in the SKE protocol.
5208 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5209 to set the channel founder authentication data. A client can
5210 claim the founder rights later by providing the authentication
5211 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5212 This way the channel founder can regain the channel founder
5213 privileges even it is left the channel. This works only on
5214 local server and the client must be connected to the same
5215 server to be able to regain the founder rights. Updated the
5216 protocol specs accordingly.
5218 Added support to the CMODE command in the client to set the
5219 founder auth data. Read the README to see how to set it.
5221 Added support to the CUMODE command to claim the founder
5222 rights. Read the README to see how to do it.
5224 Added support for the founder authentication to the Channel
5225 Entry in the server. Affected file silcd/idlist.h.
5227 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5228 server's CMODE command. Affected file silcd/command.c.
5230 * Added the following new functions into lib/silccore/silcauth.[ch]:
5231 silc_auth_get_method and silc_auth_get_data.
5233 * The server now saves the remote hosts public key to the
5234 SilcIDListData pointer. Affected file silcd/protocol.c.
5236 * The normal server now does not remove the channel entry from
5237 the cache if the founder authentication data is set. It used
5238 to remove it if the founder was the last one on the channel on
5239 the server and left the channel. The auth data is saved and
5240 if the channel is re-joined later the old entry is used with
5241 the old auth data. Affected files silcd/command_reply.c and
5244 * Removed the `pkcs' field from the SilcIDListData structure
5245 in the server; it is not used. Affected file silcd/idlist.h.
5247 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Fixed packet processing on slow links. Partial packets were
5250 never re-processed because the incoming data buffer was cleared
5251 by the application. Application must not directly clear the
5252 sock->inbuf, the packet processing routines handle it. Fixed
5253 this in client library and in server.
5255 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Fixed the WHOIS and IDENTIFY send reply function to really
5258 check whether to send list or just one entry. Affected file
5261 * Cleaned up the LEAVE command's channel key distribution. The
5262 affected file silcd/command.c.
5264 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5265 can enforce the channel mode as well. In that case the ID
5266 includes the ID of the server. The code now enforces the
5267 mode change if the router have different mode than the server.
5269 * The notify client operation with CMODE_CHANGE notify can now
5270 return NULL client_entry pointer if the CMODE was not changed
5271 by client. Application must check for this.
5273 * Added <Server ID> argument to INFO command to support server
5274 info fetching by Server ID.
5276 * Added silc_server_announce_get_channel_users to get assembled
5277 packets of channel users of the specified channel. Affected
5278 file silcd/server.[ch].
5280 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5281 was freed underneath the ID Cache.
5283 * Re-announce clients when the server received CHANNEL_CHANGE
5284 notify from the router. Affected file silcd/packet_send.c.
5286 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5289 crashed since it did not handle the fact that there is no cipher
5290 called "3" and didn't check the error condition. Now fixed.
5292 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5293 flag. It can be used to send message requests.
5295 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * Implemented the RESTART command in the client.
5299 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5300 notice type messages. Added notice printing to the user
5303 * The channel keys are not re-generated if the channel's mode
5304 is PRIVKEY, ie private key on the channel exists. Affected
5305 files silcd/server.c and silcd/command.c.
5307 * Fixed a little bug in channel message delivery when channel
5308 private keys are set in the server. Affected file is
5309 silcd/packet_send.c.
5311 * Changed the setting on channel->on_channel = TRUE from the
5312 silc_client_save_channel_key to the JOIN command reply. The
5313 key payload is not received if the private channel key is set.
5314 Affected file lib/silcclient/command_reply.c and the
5315 lib/silcclient/client_channel.c.
5317 * When the CMODE_CHANGE notify is sent and the channel private
5318 key mode is removed the channel key must be re-generated in
5319 other cells as well. Added this support for the router in the
5320 silcd/packet_receive.c.
5322 * Added new local command NOTICE to send notice message on
5323 channel. Affected file silc/local_command.[ch].
5325 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Added new local command ME to the client. It is used to send
5328 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5329 some action. Affected file silc/local_command.[ch].
5331 * Changed channel_message and private_message client operations
5332 to deliver the message flags to the application. Added also
5333 the `flags' arguments to the silc_client_send_channel_message
5334 and silc_client_send_private_message functions. Affected file
5337 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Redefined the Private Message Payload to support private message
5340 keys and to support the new private message flags. Updated
5341 the protocol specs. Flags makes it possible to have for example
5342 CTCP style messages.
5344 * Added new type SilcPrivateMessagePayload and defined an API
5345 for it in the lib/silcclient/silcprivate.[ch].
5347 * Tested private message private keys successfully. Tested the
5348 private message key set, unset and list commands with the new
5351 * Redefined the Channel Message Payload to include the channel
5352 message flags (equal with private message flags) to support
5353 for example CTCP style messages.
5355 * Defined some of the message (for channel and private message)
5356 flags. Updated the protocol specs and added the flags to the
5357 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5359 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Added SilcKeyAgreementStatus type to the key agreement routines
5362 to indicate the current status and error if one occured.
5363 The status types are defined in the lib/silcclient/silcapi.h.
5365 * Added new local command KEY that is used to set and unset private
5366 keys for channels, set and unset private keys for private messages
5367 with remote clients and to send key agreement requests and
5368 negotiate the key agreement protocol with remote client. The
5369 key agreement is supported only to negotiate private message keys,
5370 it currently cannot be used to negotiate private keys for channels,
5371 as it is not convenient for that purpose.
5373 * Fixed a minor pending callback setting bug in the function
5374 silc_client_get_client_by_id_resolve, now the function works.
5375 Affected file lib/silcclient/idlist.c.
5377 * Added function silc_net_get_local_port to get local bound
5378 port by socket. Added to lib/silcutil/silcnet.[ch].
5380 * Added `sockets' and `sockets_count' fields to the SilcClient
5381 object. They hold the sockets of the listenning sockets in
5382 the client. Listenning sockets may be for example the key
5383 agreement server. Affected file lib/silcclient/client.[ch].
5384 Added functions the silc_client_add_socket and the
5385 silc_client_del_socket. They are exported to the application
5388 * Added ~./silc/clientkeys to support other client's public keys.
5390 * Renamed verify_server_key client operation to verify_public_key
5391 and added one argument to indicate the type of the connection
5392 (server, client etc.).
5394 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Added silc_server_connection_auth_request to handle the
5397 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5398 silcd/packet_receive.[ch].
5400 * Added silc_server_send_connection_auth_request into the
5401 silcd/packet_send.c to send the connection auth request packet.
5403 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5406 * Fixed the public key authentication in responder side in the
5407 server. The `auth_data' pointer includes the SilcPublicKey
5408 not the path to the public key. Affected file silcd/protocol.c.
5410 * Implemented the public key authentication in the initiator side
5411 in the server. Affected file silcd/protocol.c.
5413 * Removed the [RedirectClient] config section from the server
5414 configuration. Is not needed and I don't want to implement it.
5416 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Cleaned up the CMODE command in the server. It now works
5419 correctly and supports all the modes defined in the protocol.
5420 Affected file is silcd/command.c.
5422 * Added `hmac_name' field to the SilcChannelEntry in the server
5423 to hold the default HMAC of the channel. It can be set when
5424 creating the channel (with JOIN command). Affected files
5427 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5428 type to indicate the change of the current cipher and hmac
5429 on the channel. Client can safely ignore the <cipher> argument
5430 (if it chooses to do so) since the CHANNEL_KEY packet will
5431 force the channel key change anyway. The <hmac> argument is
5432 important since the client is responsible of setting the new
5433 HMAC and the hmac key into use.
5435 * Fixed the CMODE command in the client library as well.
5437 * Tested CMODE command in router environment successfully.
5439 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5441 * Show the version of the remote client (or server) when connecting
5442 to the server. It is logged to the log file. Affected file
5443 is silcd/protocol.c.
5445 * Fixed the KILLED notify handling in the client library. The
5446 client must be removed from all channels when receiving the
5449 Also, do not remove the client entry when giving the KILL
5450 command but when the KILLED notify is received.
5452 * Removed silc_idlist_find_client_by_nickname from the server.
5453 Not needed anymore. Affected files silcd/idlist.[ch].
5455 * Implemented the CHANNEL_CHANGE notify type handling to the
5456 server. Affected file silcd/server.c.
5460 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Added silc_server_send_notify_invite to send the INVITE
5463 notify between routers.
5465 * Implemented the INVITE command correctly to the server.
5467 * Implemented the INVITE notify type handling in the server.
5469 * Implemented the INVITE command to the client library and on the
5472 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * Added function silc_server_get_client_resolve to find the
5475 client entry by ID from all ID lists and then resolve it
5476 (using WHOIS) if it cannot be found. Affected file is
5479 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Implemented the BAN command to the client library.
5483 * The JOIN command in the server now checks the invite list
5486 * Changed the silc_command_reply_payload_encode_va and the
5487 silc_command_payload_encode_va to support that if argument is
5488 NULL it ignores and checks the next argument. Affected file
5489 lib/silccore/silccommand.c.
5491 * Added silc_server_send_notify_ban to send the BAN notify
5492 type between routers.
5494 * Chaned the silc_notify_payload_encode to support that if
5495 argument is NULL it ignores and checks the next argument.
5496 Affected file lib/silccore/silcnotify.c.
5498 * Tested ban lists in router environment successfully.
5500 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * Implemented BAN command to the server, in silcd/command.[ch].
5504 * Removed the BAN and INVITE_LIST modes from the CMODE command
5507 * Added function silc_string_match to regex match two strings.
5508 Affected files lib/silcutil/silcutil.[ch].
5510 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Redefined parts of the SilcChannelEntry in the server to support
5513 the new ban and invite lists.
5515 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Redefined the INVITE command. The same command can be used to
5518 invite individuals to the channel but also to manage the invite
5519 list of the channel (to add to and remove from the invite list).
5520 Updated the protocol specs.
5522 * Added new command SILC_COMMAND_BAN that can be used to manage
5523 the ban list of the channel. Updated the protocol specs.
5525 * Removed the channel modes: the SILC_CMODE_BAN and the
5526 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5527 in the CMODE command. The equivalent features are now available
5528 using INVITE and BAN commands. Updated the protocol specs.
5530 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5531 in the network about change in the current ban list. The notify
5532 type is not used by the client.
5534 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5535 support the invite lists.
5537 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5539 * Added new function silc_string_regexify that converts string
5540 including wildcard characters into regex string that can
5541 be used by the GNU regex library. Added into the file
5542 lib/silcutil/silcutil.[ch].
5544 Added silc_string_regex_combine to combine to regex strings
5545 into one so that they can be used as one regex string by
5546 the GNU regex library. Added into the file
5547 lib/silcutil/silcutil.[ch].
5549 Added silc_string_regex_match to match two strings. It returns
5550 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5552 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Imported GNU regex to the soruce tree into lib/contrib.
5555 Fixed some compiler warning from the regex.c.
5557 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5559 * Fixed MOTD command in the server to work in router environment.
5561 * Fixed the MOTD command in the client library to support
5562 the server argument in the command.
5564 * Added `nickname_len' argument to the silc_idlist_add_client
5565 in the server, as the `nickname' argument may be binary data
5568 * Added silc_idlist_get_channels to return all channels from
5571 * Implemented LIST command to the server. Affected file is
5574 * Implemented the LIST command to the client library and on the
5577 * Added [<user count>] argument to the LIST command reply.
5578 With private channels the user count is not shown.
5580 * Updated TODO and README.
5582 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5584 * The client entry's data.registered must be TRUE even with
5585 global client entry on global client list. The data.registered
5586 is used to check whether the client is anymore in the network,
5587 for example with WHOWAS command so it must be valid.
5589 * Fixed the WHOWAS command in the server. It now actually works
5590 in router environment. Added function into silcd/command_reply.c
5591 silc_server_command_reply_whowas_save.
5593 * Added silc_idlist_purge function to the silcd/idlist.c
5594 to periodically purge the ID Cache.
5596 * Fixed INFO command in the server. It works now in router
5597 environment. Added <server name> argument to the INFO command
5598 reply. Updated the protocol specs.
5600 * Fixed minor bug in silc_idcache_purge to not purge if the
5601 expire value is zero.
5603 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5604 they were buggy because of the WHOWAS information.
5606 * Fixed local command MSG to handle the async resolving of
5607 the remote client properly. It used to fail the first MSG.
5608 Affected file silc/local_command.c.
5610 * Added `data_len' field to SilcIDCache context.
5612 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Update TODO. Todo in commands in the server.
5616 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5619 used by routers as broadcast packet to inform other routers
5620 about the changed user mode.
5622 Implemented the notify handling in the server. Affected file is
5623 silcd/packet_receive.c. Added the function
5624 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5626 * Added new generic Channel Payload and deprecated the New Channel
5627 Payload. The New Channel Payload is now the generic Channel
5630 * Added new argument `mode' to the silc_server_send_new_channel
5631 as it is required in the Channel Payload now.
5633 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5634 and created a new and real SilChannelPayload to represent the
5635 new generic Channel Payload. Implemented the encode/decode
5636 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5638 * Added silc_server_get_client_channel_list to return the list
5639 of channels the client has joined for WHOIS command reply.
5640 Affected file silcd/server.[ch].
5642 * Implemented the channel list sending in the WHOIS command reply
5643 in server and in the client.
5645 Implemented the channel list displaying on the user interface
5646 as well. Affected file silc/client_ops.c.
5648 * Added silc_channel_payload_parse_list to parse list of Channel
5649 Payloads. It returns SilcDList list of SilcChannelPayloads.
5650 Client for example can use this function to parse the list of
5651 channels it receives in the WHOIS command reply. The caller
5652 must free the list by calling silc_channel_payload_list_free.
5653 Affected files lib/silccore/silcchannel.[ch].
5655 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Added one new argument <user mode> to the WHOIS command reply
5658 to return the mode of the user in SILC. Updated the protocol
5661 Implemented it to the server and client.
5663 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Fixed the mode printing on the user interface on joining.
5666 Affected file silc/client_ops.c.
5668 * Implemented the UMODE command and user modes in general to the
5669 client library and to the user interface.
5671 * Implemented the UMODE command to the server.
5673 * The server now sends UNKNOWN_COMMAND error status if client sends
5674 unknown command. Affected file silcd/command.c.
5676 * All server commands now handle the command identifier the right
5677 way when sending the command reply to the client. The client can
5678 use to identify the command replies with the identifier.
5680 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5682 * Added silc_server_get_client_route to resolve the route to
5683 the client indicated by the client ID. Affected file is
5686 * Added silc_server_relay_packet as general function to relay
5687 packet to arbitrary destination. This deprecates functions
5688 like _send_private_message_key, _relay_notify etc. Affected
5689 file is silcd/packet_send.[ch].
5691 Removed silc_server_send_key_agreement,
5692 silc_server_send_private_message_key and
5693 silc_server_packet_relay_notify functions from the file
5694 silcd/packet_send.[ch].
5698 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5699 server. Affected file silcd/packet_receive.[ch].
5701 * Implemented the KILL command to the client. Implemented the
5702 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5703 Affected files lib/silcclient/command[_reply].c and
5704 lib/silcclient/client_notify.c. Implemented the KILL notify
5705 printing in the user inteface.
5707 * Fixed a lot silc_parse_nick memory leaks from the client
5708 library in the file lib/silcclient/command.c.
5710 * Changed the silc_server_send_notify_on_channels's `sender'
5711 argument from SilcSocketConnection to SilcClientEntry to
5712 check the sender as entry and not as connection object and not
5713 to send to the client provided as argument. The affected file
5714 is silcd/packet_send.[ch].
5716 * The notify packets that are destined directly to the client used
5717 to not to be processed by the server. Now changed that and the
5718 server processes all notify packets. After relaying the packet
5719 to the client the notify packet is processed in the server.
5721 * The silc_server_free_client_data now checks whether there is
5722 pending outgoing traffic for the client and purges the data to
5723 the network before removing the client entry.
5725 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5728 an client is killed from the SILC Network. Updated the protocol
5731 Added new function silc_server_send_notify_killed to the
5732 silcd/packet_send.[ch].
5734 * Added function silc_server_packet_relay_notify to relay notify
5735 packets that are destined directly to a client. In this case
5736 the server does not process the notify packets but merely relays
5737 it to the client. Affected file silcd/packet_send.[ch].
5739 Added also silc_server_packet_process_relay_notify to check
5740 whereto relay the notify. Affected file is
5741 silcd/packet_receive.[ch].
5743 * Implemented the KILL command to the server.
5747 * Added the backup schema desgined last fall to the protocol
5748 specs for everyone to see. The specification is in the
5749 *-spec-xx.txt draft and the packet type definitions for the
5750 backup routers is in *-pp-xx.txt draft. Thusly, added also
5751 new packet type SILC_PACKET_CELL_ROUTERS.
5753 * A big security problem in the implementation discovered. The
5754 signoff of an client did not cause new channel key generation
5755 which it of course should've done. The channel keys must be
5756 always re-generated when client leaves (or signoffs) the channel.
5757 The silc_server_remove_from_channels funtion now handles
5758 the channel key re-generation.
5760 * Added `sender' argument to the silc_server_send_notify_on_channels
5761 to not to send the client provided as argument. Affected file
5762 silcd/packet_send.[ch].
5764 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Implemented OPER and SILCOPER commands into the server and
5769 * Added silc_auth_verify and silc_auth_verify_data to verify
5770 the authentication directly from the authentication payload.
5771 It supports verifying both passphrase and public key based
5772 authentication. Affected file lib/silccore/silcauth.[ch].
5774 * Added `hash' field to the SilcIDListData structure. It is the
5775 hash negotiated in the SKE protocol. Affected file is
5778 * Slight redesigning of the SilcAuthPayload handling routines.
5779 Do not send SilcPKCS but SilcPublicKey as argument.
5781 * Implemented the public key authentication support to the
5782 serverconfig. The public key is loaded from the provided path
5783 and saved as authentication data to void * pointer. Thus,
5784 changed the unsigned char *auth_data to void *auth_data;
5786 * Fixed SHUTDOWN command to send the reply before the server
5787 is shutdown. :) Affected file silcd/command.c.
5789 * Fixed fatal bug in CONNECT command. The hostname was invalid
5790 memory and server crashed. Affected file silcd/command.c.
5792 * Fixed fatal bug in CLOSE command. The server_entry became
5793 invalid but was referenced later in the command. Affected file
5796 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5798 * Fixed fatal bug in failure packet handling. Server ignored
5799 the failure and thus crashed when it came.
5803 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5805 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5806 that the command may be executed only once in (about) 2 seconds.
5807 The old SILC_CF_LAG flag is same but allows command bursts up
5808 to five before limiting.
5810 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5811 server code. Various commands now includes the CF_LAG_STRICT
5812 flag to disallow any kind of miss-use of the command.
5814 * Fixed the silc_buffer_unformat to not to allocate any data
5815 if the length of the data is zero. It used to allocate the
5816 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5818 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Changed the format of AdminConnection configuration section
5821 in the server. Added username of the admin to the format.
5822 Affected files silcd/serverconfig.[ch].
5824 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5825 to return admin configuration data by host, username and/or
5828 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5830 * Implemented WHOWAS command to the server. Added the functions:
5832 silc_server_command_whowas_parse,
5833 silc_server_command_whowas_send_reply,
5834 silc_server_command_whowas_from_client and
5835 silc_server_command_whowas_from_server
5837 * Added <Client ID> argument to the WHOWAS command reply. Updated
5838 the protocol specs accordingly.
5840 * Implemented WHOWAS command and command_reply to the client
5843 Implemented the WHOWAS printing on the user interface.
5845 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5847 * Added new argument to the WHOWAS command reply, the real name.
5848 It is an optional argument. Updated the protocol specs.
5850 * Added SilcIDCacheDestructor callback that is registered when
5851 the SilcIDCache is allocated. The callback is called when
5852 an cache entry in the ID Cache expires, or is purged from the
5853 cache. Added into lib/silccore/idcache.[ch].
5855 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5856 to destruct the client entries when the cache entry expires.
5857 Other ID Cache's in server and in the client library ignores
5860 * If the ID Cache entry's `expire' field is zero then the entry
5861 never expires. Added boolean `expire' argument to the
5862 silc_idcache_add function in the lib/silccore/idcache.[ch].
5863 If it is TRUE the default expiry value is used.
5865 * Added silc_server_free_client_data_timeout that is registered
5866 when client disconnects. By default for 5 minutes we preserve
5867 the client entry for history - for WHOWAS command.
5869 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * Added support to the server to enforce that commands are not
5872 executed more than once in 2 seconds. If server receives
5873 commands from client more frequently, timeout is registered
5874 to process the commands. Affected file silcd/command.c.
5875 Added new function silc_server_command_process_timeout.
5877 * Changed NICK_NOTIFY handling in client library to check that
5878 if the client's nickname was changed, so there is no need to
5879 resolve anything from the server.
5881 * Removed error printing from the WHOIS and IDENTIFY commands.
5882 If error occurs then it is ignored silently in the client library.
5883 The application, however, may map the received error to
5884 human readable error string. The application currently maps
5885 the NO_SUCH_NICKNAME error to string.
5887 * Made the command status message public to the application. Moved
5888 them from lib/silcclient/command_reply.c to
5889 lib/silcclient/command_reply.h. The application can map the
5890 received command status to the string with the
5891 silc_client_command_status_message function.
5893 * Added check to the server to check that client's ID is same
5894 as the Source ID in the packet the client sent. They must
5897 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Added dist-bzip hook to the Makefile.am to make bzip2
5900 compressed distributions.
5902 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * Server now enforces the maximum length for the nickname and
5905 the channel as protocol specification dictates. 128 bytes for
5906 nickname and 256 bytes for channel name.
5908 * Moved the WHOIS printing to the application. The client libary
5909 does not print out the WHOIS information anymore, the application
5910 must do it. Renamed silc_client_command_reply_whois_print to
5911 the silc_client_command_reply_whois_save.
5913 The client's idle time is also sent to the application now, and
5914 the idle is shown on screen.
5916 * Added silc_client_command_reply_identify_save to save the
5917 received IDENTIFY entries.
5919 * Do not check for channel private keys in message sending and
5920 reception if the channel does not have the PRIVKEY mode set.
5921 Affected file lib/silclient/client_channel.c.
5923 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5926 just surfaced after chaning the JOIN procedure.
5928 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Added silc_client_get_clients_by_list to get client entries
5931 from Client ID list, that is returned for example by JOIN
5932 and USERS command replies. The application should use this
5933 function for example when JOIN command reply is received to
5934 resolve the clients already on the channel (library does not
5935 do that anymore as USERS command reply is not used in the JOIN
5936 procedure anymore). Affected files lib/silcclient/silcapi.h and
5937 lib/silcclient/idlist.c.
5939 * JOIN command reply and USERS command reply returns now SilcBuffer
5940 pointers instead of unsigned char pointers when returning
5941 the client list and mode list.
5943 * Added <Client ID> argument to the JOIN command reply, mainly
5944 for the server to identify for which client the command was
5945 originally sent. Updated protocol specs accordingly.
5947 * Added SilcDlist private_key pointer to the SilcChannelEntry
5948 in the client to support the channel private keys. Affected
5949 file is lib/silcclient/idlist.h.
5951 * Added SilcChannelPrivateKey argument to the function
5952 silc_client_send_channel_message so that application can choose
5953 to use specific private ke if it wants to. If it is not provided,
5954 the normal channel key is used, unless private keys are set.
5955 In this case the first (key that was added first) is used
5956 as the encryption key.
5958 * Implemented the support for channel private key handling.
5959 Implemented the following functions:
5961 silc_client_add_channel_private_key,
5962 silc_client_del_channel_private_keys,
5963 silc_client_del_channel_private_key,
5964 silc_client_list_channel_private_keys and
5965 silc_client_free_channel_private_keys
5967 Affected file lib/silcclient/client_channel.c.
5969 * Added the support for the private keys in the channel message
5970 sending and encryption and in the message reception and
5971 decryption. Affected funtions are
5972 silc_client_send_channel_message and silc_client_channel_message.
5974 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Added SKE's key verify callback to the client library's
5977 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5979 * Removed the statement that server (or router) must send USERS
5980 command reply when joining to the channel so that the client
5981 knows who are on the channel. Instead, the client list and
5982 client's mode list is now sent in the JOIN command reply to the
5983 client who joined channel. This is better solution.
5985 * Added function silc_server_get_users_on_channel and function
5986 silc_server_save_users_on_channel to the silcd/server.[ch].
5988 * Removed function silc_server_command_send_users from the
5991 * Do not show topic on the client library anymore. The topic is
5992 sent in the command reply notify to the application and the
5993 application must show the topic now.
5995 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Added client searching by nickname hash into the IDENTIFY and
5998 WHOIS commands in the server as they were clearly missing from
5999 them. Affected file is silcd/command.c.
6001 * Fixed a bug in private message receiving in the client library.
6002 The remote ID was freed and it wasn't supposed, now it is
6005 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Minor fix to the channel payload; allocate the data area, as it
6008 needs to be of specific length.
6010 * If the key agreement port is zero then the operating
6011 system will define the bound port. Affected files are
6012 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6014 * Added new function silc_channel_payload_decrypt into the file
6015 lib/silccore/silcchannel.[ch].
6017 * Moved the channel message etc, check from silc_packet_decrypt
6018 to applications. The library calls now a generic
6019 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6020 when the packet is either normal or special. This was done to
6021 allow more wide range of checking that was not allowed when
6022 the code was in library. Now applications can do virtually any
6023 checks to the packet and return to the library the decision how
6024 the packet should be processed. Affected files are
6025 lib/silccore/silcpacket.[ch].
6027 Added silc_server_packet_decrypt_check to the server and
6028 silc_client_packet_decrypt_check to the client library.
6030 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6031 to send with specified source and destination information.
6033 * Channel message delivery between routers was broken after the
6034 channel key distribution was fixed earlier. The channel key
6035 was used be to distributed to other routers as well which is not
6036 allowed by the protocol. Now this is fixed and channel keys
6037 really are cell specific and the channel message delivery between
6038 routers comply with the protocol specification.
6040 * Fixed various commands in server to check also the global list
6041 for the channel entry and not just the local list. The affected
6042 file silcd/command.c.
6044 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Added assert()s to buffer formatting and unformatting routines
6047 to assert (if --enable-debug) when error occurs. Affected
6048 file: lib/silcutil/silcbuffmt.c.
6050 * Changed to auto-reconnect to check whether the remote host is
6051 router and register the re-connect timeout if it is. It used
6052 to check that whether we are normal server, but router must do
6053 auto-reconnect with another router as well. Affected file
6056 * Removed the [<key len>] option from CMODE command as the cipher
6057 name decides the key length, nowadays. See the defined ciphers
6058 from the protocol specification.
6060 * Added [<hmac>] option to the CMODE command to define the HMAC
6061 for the channel. Added SILC_CMODE_HMAC channel mode.
6063 * Added [<hmac>] option for the JOIN command so that user can
6064 select which HMAC is used to compute the MACs of the channel
6067 * Added Hmac field to the Channel Message Payload. The integrity
6068 of plaintext channel messages are now protected by computing
6069 MAC of the message and attaching the MAC to the payload. The
6070 MAC is encrypted. Now, it is clear that this causes some
6071 overhead to the size of the packet but rationale for this is that
6072 now the receiver can verify whether the channel message decrypted
6073 correctly and also when private keys are set for the channel the
6074 receiver can decrypt the packet with several keys and check from
6075 the MAC which key decrypted the message correctly.
6077 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6078 lib/silccrypt/silccipher.[ch].
6080 * Added silc_hash_len to return the digest length into the
6081 lib/silcrypt/silchash.[ch].
6083 * Rewrote parts of Silc Channel Payload interface in the
6084 lib/silccore/silcchannel.[ch]. The encode function now also
6085 encrypts the packet and parse function decrypts it.
6087 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Fixed a minor formatting bug in the SKE's key material processing.
6090 It actually might have processed the keys wrong way resulting
6093 * Redefined the mandatory HMAC algorithms and added new algorithms.
6094 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6095 and hmac-md5 truncated to 96 bits. The mandatory is now
6096 hmac-sha1-96. Rest are optional (including the one that used
6097 to be mandatory). Rationale for this is that the truncated HMAC
6098 length is sufficient from security point of view and can actually
6099 make the attack against the HMAC harder. Also, the truncated
6100 HMAC causes less overhead to the packets. See the RFC2104 for
6103 * Added new [hmac] configuration section. The SKE used to use
6104 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6105 is of course wrong. The official names that must be proposed in
6106 the SKE are the ones defined in the protocol specification
6107 (hmac-sha1-96 for example). The user can configure any hmac
6108 using any hash function configured in the [hash] section. At
6109 least, the mandatory must be configured.
6111 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6113 * Added HMAC list to the SKE proposal list. It has now both
6114 hash algorithm list and HMAC list. This makes the protocol
6115 incompatible with previous versions. The SKE now seems to work
6116 the way it is supposed to work, for the first time actually.
6118 * Defined plain Hash algorithms to the protocol specification.
6121 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Implemented support for key agreement packets into the server.
6124 Added functions silc_server_key_agreement and
6125 silc_server_send_key_agreement. Other than these functions,
6126 server has nothing to do with this packet.
6128 * Added support for private message key packets into the server.
6129 Added functions silc_server_private_message_key and
6130 silc_server_send_private_message_key.
6134 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6135 called in the protocol's final callback instead in the END
6136 protocol state. This makes a little more sense and in the same
6137 time in client we can use the same protocol routines for normal
6138 key exchange and to key agreement packet handling as well.
6140 * Added to both client's and server's KE protocol context the
6141 SilcSKEKeyMaterial pointer to save the key material. We will
6142 bring the key material to the protocol's final callback by doing
6143 this. The final callback must free the key material.
6145 * Added SKE's packet_send callback into client's KE protocol
6146 context so that the caller can choose what packet sending function
6147 is used. This way we can use different packet sending when
6148 doing normal SKE when doing key agreement packet handling (in
6149 the key agreement packet handling we do not want to encrypt
6152 * Implemented the responder side of the key agreement routines
6153 in the client. The client can now bind to specified port and
6154 accept incoming key negotiation. The key material is passed
6155 to the application after the protocol is over.
6157 * Implemented the processing of incoming Key Agreement packet
6158 in the client. Added function silc_client_key_agreement to
6161 * Implemented the intiator side of the key agreement routines
6162 in the client. The client can now initiate key agreement with
6163 another remote client. The key material is passed to the
6164 application after the protocol is over.
6166 * Created client_keyagr.c to include all the key agreement
6169 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6170 SILC_TASK_CALLBACK except that it is not static.
6172 * Created client_notify.c and moved the Notify packet handling
6173 from the client.[ch] into that file.
6175 * Created client_prvmsg.c and moved all private message and
6176 private message key routines from the client.[ch] into that file.
6178 * Create client_channel.c and moved all channel message and
6179 channel private key routines from the client.[ch] into that file.
6181 * Changed silc_client_get_client_by_id_resolve to resolve with
6182 WHOIS command instead of IDENTIFY command, in the file
6183 lib/silclient/idlist.c.
6185 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Implemented the SKE's responder side to the Client library.
6189 * When FAILURE is received to the protocol do not trust it
6190 blindly. Register a timeout to wait whether the remote closes
6191 the connection as it should do it, only after that process the
6192 actual failure. This was changed to both client and server.
6194 * Added client_internal.h to include some of the structures
6195 there instead of client.h in lib/silcclient/.
6197 * Added function silc_task_unregister_by_callback to unregister
6198 timeouts by the callback function.
6200 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * Some "Incomplete WHOIS info" errors has been appearing on the
6203 log files. Took away the entry->userinfo check from WHOIS
6204 reply sending. The entry->userinfo is now " " if client did not
6205 provide one. I thought this was fixed earlier but something
6206 is wrong still. Let's see if the error still appears.
6208 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * Fixed a minor bug in the login when the channel key is
6211 re-generated in the server. It used to generate the key in
6212 wrong order and thus caused problems in the channel traffic.
6214 * Fixed a minor bug in channel key distsribution after
6215 KICK command. The key was not sent to the router even though
6218 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6220 * Added silc_ske_process_key_material_data as generic routine
6221 to process any key material as the SILC protocol dictates. The
6222 function is used by the actual SKE library but can be used by
6223 applications as well. This relates to the private message keys
6224 and the channel private keys since they must be processed the
6225 same way the normal SILC session keys. The protocol dictates
6226 this. Affected files: lib/silcske/silcske.[ch].
6228 Added also silc_ske_free_key_material to free the
6229 SilcSKEKeyMaterial structure.
6231 * Defined silc_cipher_set_key function to set the key for
6232 cipher without using the object's method function. The affected
6233 files: lib/silccrypt/silccipher.[ch].
6235 * Implemented silc silc_client_add_private_message_key,
6236 silc_client_add_private_message_key_ske,
6237 silc_client_del_private_message_key,
6238 silc_client_list_private_message_keys and
6239 silc_client_free_private_message_keys functions in the
6242 Added functions silc_client_send_private_message_key to send
6243 the Private Message Key payload and silc_client_private_message_key
6244 to handle incoming Private Message Key payload.
6246 * Added Cipher field to the Private Message Key payload to set
6247 the cipher to be used. If ignored, the default cipher defined
6248 in the SILC protocol (aes-256-cbc) is used.
6250 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * Removed lib/silcclient/ops.h file.
6254 Redefined parts of the SILC Client Library API. Created new
6255 file silcapi.h that deprecates the ops.h file and defines the
6256 published Client Library API. Defined also private message key
6257 API and channel private key API into the file.
6259 This is the file that the application must include from the
6260 SILC Client Library. Other files need not be included by
6261 the application anymore.
6263 * Added new key_agreement client operation callback and also
6264 defined the Key Agreement library API for the application.
6266 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6269 is used by clients to request key negotiation between another
6270 client in the SILC network. If the negotiation is started it
6271 is performed using the SKE protocol. The result of the
6272 negotiation, the secret key material, can be used for example
6273 as private message key.
6275 Implemented the Key Agreement payload into the files
6276 lib/silccore/silauth.[ch].
6278 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * Redefined ciphers for the SILC protocol. Added some new ciphers
6281 and defined the key lengths for the algorithms. Changed the
6282 code accordingly. The default key length is now 256 bits.
6284 * Fixed SKE key distribution function silc_ske_process_key_material
6285 when the key length is more than 128 bits. The default key
6286 length in SILC is now 256 bits.
6288 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6289 to indicate unsupported algorithm.
6291 * Renamed rijndael.c to aes.c and all functions as well.
6293 * Fixed a long standing channel key setting bug in client library.
6294 Weird that it has never surfaced before.
6296 * Fixed bug in channel deletion. If the entire channel is removed
6297 then it must also delete the references of the channel entry
6298 from the client's channel list as the client's channel entry and
6299 the channel's client entry share same memory.
6301 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Implemented CONNECT and SHUTDOWN commands in the client.
6305 * Implemented CLOSE command to the client.
6307 * Added the function silc_idlist_find_server_by_name into the
6308 files silcd/idlist.[ch].
6310 Added the function silc_idlist_find_server_by_conn into the
6311 files silcd/idlist.[ch].
6313 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6315 * DIE command was renamed to SHUTDOWN. Updated the both code
6318 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6319 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6321 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6324 * Added function silc_server_create_connection function to create
6325 connection to remote router. My server implementation actually
6326 does not allow router to connect to normal server (it expects
6327 that normal server always initiates the connection to the router)
6328 so the CONNECT command is only good for connecting to another
6331 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6334 or some other client was kicked from the channel.
6336 Implemented the handling of the notify type to both client
6339 Implemented silc_server_send_notify_kicked to send the KICKED
6340 notify. It is used to send it to the server's primary router.
6342 * Implemented the KICK command into server and client.
6344 * Added `query' argument to the silc_idlist_get_client function
6345 to indicate whether to query the client from server or not if
6348 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6349 to indicate that the client is not channel founder.
6353 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Removed the rng context from SilcPacketContext structure and
6356 changed that the packet routine uses the Global RNG API.
6358 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6360 * Added support for quit message that client can "leave" on the
6361 channel when it quits the SILC. It is ditributed inside the
6362 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6364 Added silc_server_free_client_data that will take the
6365 signoff message as argument.
6367 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6369 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Updated parts of the protocol specification to keep it up
6374 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6377 payloads in one packet.
6379 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6380 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6381 use now the new List flag.
6383 * Also deprecated the following packet types: REPLACE_ID,
6384 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6386 * Added list support for Notify packet in server.
6388 * Added silc_server_send_notify_channel_change to send the
6389 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6390 the silc_server_send_replace_id.
6392 * Added silc_server_send_notify_nick_change to send the
6393 NICK_CHANGE notify type. Deprecates the function
6394 silc_server_send_replace_id.
6396 * Added silc_server_send_notify_join to send the JOIN notify type.
6397 Deprecates the function silc_server_send_new_channel_user.
6399 * Added silc_server_send_notify_leave to send LEAVE notify type.
6400 Deprecates the function silc_server_send_remove_channel_user.
6402 * Added silc_server_send_notify_cmode and
6403 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6404 types. Deprecates the silc_server_send_set_mode function.
6406 * Added SERVER_SIGNOFF notify type to indicate that server has
6407 quit. This means that all clients on the channel from that
6408 server will drop. This can be also used when netsplit happens.
6410 Deprecated REMOVE_ID packet type since it is not needed anymore
6413 Added silc_server_send_notify_server_signoff to send the
6414 SERVER_SIGNOFF notify type. Deprecates the function
6415 silc_server_send_remove_id.
6417 Added also silc_server_send_notify_signoff to send the
6418 SIGNOFF notify type.
6420 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6421 SILC protocol from this day on. Changed the protocol
6422 specification as well.
6424 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6425 notify type. It is used between routers to notify about
6426 topic changes on a channel.
6428 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6431 * Partly updated the protocol specification to comply with the
6432 changes now made. It is still though a bit outdated.
6434 * The JOIN notify type now takes one extra argument <Channel ID>.
6435 The packet used to be destined to the channel but now the
6436 JOIN type may be sent as list thus it is impossible to
6437 destine it to any specific channel. By adding this argument
6438 it is again possible.
6440 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6442 * Added CREDITS file. The CHANGES and CREDITS file will appear
6443 in the distribution as well.
6445 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6447 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6448 types in the server's silcd/packet_receive.c.
6450 * Implemented CMODE and CUMODE to work in router environment.
6452 * Fixed minor encoding and decoding buglet from the
6453 lib/silccore/silcmode.c.
6455 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6458 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6460 * Changed all SilcConfigServer* and silc_config_server* to
6461 SilcServerConfig* and silc_server_config*, respectively.
6464 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * Associated the ID (client or server ID) to the Authentication
6467 Payload to avoid any possibility of forging. Updated the
6468 protocol specification and the code accordingly.
6470 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6472 * The RSA key length is now save to the RsaKey context in the
6473 key generation process in lib/silccrypt/rsa.c. The key length
6474 is now used to figure out the maximum size of the block allowed
6475 to be encrypted/signed.
6477 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6478 is equivalent to the silc_mp_mp2bin but does not allocate any
6481 * Changed silc_mp_mp2bin API to take length argument. If it is
6482 non-zero then the buffer is allocated that large. If zero, then
6483 the size is approximated using silc_mp_sizeinbase, which however
6486 * Created Global RNG API which is global RNG that application can
6487 initialize. After initializing, any routine anywhere in the
6488 code (including library) can use RNG without allocating a new
6489 RNG object. This was done to allow this sort of use of the
6490 RNG in code that has no chance to allocate RNG object. All
6491 applications currently allocate this and many routines in the
6492 library use this. Affected file lib/silccrypt/silcrng.[ch].
6494 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6495 it to use the Global RNG API.
6497 * Defined Authentication Payload into protocol specification that
6498 is used during SILC session to authenticate entities. It is
6499 used for example by client to authenticate itself to the server
6500 to obtain server operator privileges.
6502 Implemented this payload into the lib/silccore/silcauth.[ch].
6503 Implemented also routines for public key based authentication
6504 as the new protocol specification dictates.
6506 Moved definitions of different authentication methods from
6507 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6509 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6510 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6511 silc_pkcs_verify_with_hash functions into the file
6512 lib/silccrypt/silcpkcs.[ch].
6514 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6516 * The client entry's userinfo pointer must be always valid.
6517 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6518 will fail since it requires the userinfo. Now, the userinfo
6519 is allocated as "" if actual userinfo does not exist. Actually,
6520 it must exist and it is totally Ok to drop client connections
6521 that does not announce the userinfo. However, we will make
6522 this workaround for now.
6524 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6525 to return the remote port by socket.
6527 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6529 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6530 SILC_SERVER_PENDING_EXEC and added an new macro
6531 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6532 data or when error occurs while processing the pending command.
6534 Added new argument `destructor' into silc_server_command_pending
6535 and to the SilcServerCommandPending object. This destructor is
6536 now called after calling the pending callback or if error occurs
6537 immediately. If error occurs the actual pending callback won't
6538 be called at all - only the destructor. The destructor may be
6539 NULL if destructor is not needed.
6541 All this applies for client library code as well. Similar
6542 changes were made there as well for the pending commands.
6544 In the client, the application must now allocate the
6545 SilcClientCommandContext with the silc_client_command_alloc
6548 * Added reference counter to the SilcServerCommandContext. Added
6549 function silc_server_command_alloc and silc_server_command_dup
6552 Same type of functions added to the client library for the same
6555 * Removed the cmd_ident from IDListData away since it is now
6556 global for all connections. It is the command identifier used
6557 in command sending and with pending commands. The affected file
6560 * Added reference counter to the SilcSocketConnection objecet to
6561 indicate the usage count of the object. The object won't be
6562 freed untill the reference counter hits zero. Currently only
6563 server uses this, and client ignores it. The client must be
6564 set to use this too later. The affected files are
6565 lib/silccore/silcsockconn.[ch]. Added also the function
6566 silc_socket_dup to increase the reference counter.
6568 This was mainly added because it is possible that the socket
6569 is removed underneath of pending command or other async
6570 operation. Now it won't be free'd and proper DISCONNECTING
6571 flags, etc. can be set to avoid sending data to connection that
6572 is not valid anymore.
6574 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6575 the connection. After that it sets SILC_SET_DISCONNECTED.
6576 It is, however, possible that the socket data is not still freed.
6577 The silc_server_packet_process now checks that data is not
6578 read or written to connection that is DISCONNECTED. The socket
6579 get's freed when the reference counter hits zero.
6581 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Changed the client operation API: channel_message operation's
6584 `sender' is now the client entry of the sender, not the nickname
6585 and the `channel' is the channel entry, not the channel name.
6587 In the private_message operation the `sender' is now also the
6588 client entry of the sender not the nickname.
6590 Affected file is lib/silcclient/ops.h and all applications
6591 using the client operations.
6593 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Moved the calling of ops->connect() from connect_to_server_final
6596 into receive_new_id functin since that is the point when the
6597 client is actually allowed to send traffic to network. The
6598 affected file is lib/silcclient/client.c.
6600 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6603 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6604 (if needs broadcasting) instead of broadcasting the packets one
6605 by one which would make a burst in the network traffic.
6607 * Added `broadcast' argument to the functions in silcd/server.[ch]
6608 silc_server_create_new_channel[_with_id] to indicate whether
6609 to send New Channel packet to primary router.
6611 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6613 * Added new function into the silcd/server.[ch] files:
6614 silc_server_create_new_channel_with_id to create new channel with
6615 already existing Channel ID.
6617 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6618 lib/silccore/silcpacket.h. This packet is used t send list of
6619 Set Mode payloads inside one packet. Server uses this to set
6620 the modes for the channels and clients on those channels, that it
6621 announced to the router when it connected to it. The protocol
6622 specification has been updated accordingly.
6624 * The silc_server_new_channel did not handle the packet coming
6625 from normal server as it normally does not send that. However,
6626 when it announces its channels it does send it. Implemented
6627 the support for that.
6629 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6630 into the file lib/silccore/id.h.
6632 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Fixed memory leaks in the functions silc_idlist_del_client,
6635 silc_idlist_del_channel and silc_idlist_del_server in the file
6636 silcd/idlist.c. All of those leaked like a sieve.
6638 * Fixed some small memory leaks in the client's function
6639 silc_client_notify_by_server.
6641 * Added functions into silcd/server.c: silc_server_announce_clients,
6642 silc_server_announce_channels and silc_server_announce_server.
6643 These functions are used by normal and router server to announce
6644 to its primary router about clients, channels and servers (when
6645 router) that we own. This is done after we've connected to the
6648 These functions effectively implements the following packet types:
6649 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6650 and SILC_PACKET_NEW_ID_LIST.
6652 * Added new functions into the silcd/packet_receive.[ch]:
6653 silc_server_new_id_list, silc_server_new_channel_list and
6654 silc_server_new_channel_user_list to handle the incoming
6655 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6657 * Added support of changing Channel ID in the function
6658 silc_server_replace_id. If the server that announces a channel
6659 to the router already exists in the router (with same name but
6660 with different Channel ID), router is responsible to send
6661 Replace ID packet to the server and force the server to change
6662 the Channel ID to the one router has.
6664 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6665 client that the Channel ID has been changed by the router. The
6666 normal server sends this to the client. Client must start using
6667 the new Channel ID as the channel's ID.
6669 Implemented handling of this new type into lib/silcclient/client.c
6670 into the function silc_client_notify_by_server.
6672 * Added new function silc_idlist_replace_channel_id into the files
6673 silcd/idlist.[ch] to replace the Channel ID.
6675 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6677 * Call silc_server_command_identify_check always when processing
6678 the IDENTIFY command in silcd/command.c
6680 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6682 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6683 send keepalive packets. The packet can be sent by clients,
6684 servers and routers.
6686 Added function silc_socket_set_heartbeat into the file
6687 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6688 If not set, the heartbeat is not performed. The actual
6689 heartbeat is implemented in the low level socket connection
6690 library. However, application is responsible of actually
6693 Added silc_server_send_heartbeat to send the actual heartbeat
6694 packet into silcd/packet_send.[ch]. Server now performs
6695 keepalive with all connections.
6697 * Added silc_task_get_first function into lib/silcutil/silctask.c
6698 to return the timeout task with shortest timeout. There was a bug
6699 in task unregistration that caused problems. TODO has been
6700 updated to include that task system must be rewritten.
6702 * The client library will now resolve the client information when
6703 receiving JOIN notify from server for client that we know but
6704 have incomplete information.
6706 * Rewrote parts of silc_server_remove_from_channels and
6707 silc_server_remove_from_one_channel as they did not remove the
6708 channel in some circumstances even though they should've.
6710 * Encryption problem encountered in server:
6712 The LEAVE command used to send the Channel Key packet to the
6713 router immediately after generating it. However, the code
6714 had earlier sent Remove Channel user packet but not immediately,
6715 ie. it was put to queue. The order of packets in the router
6716 was that Channel Key packet was first and Remove Channel User
6717 packet was second, even though they were encrypted in the
6718 reverse order. For this reason, MAC check failed. Now, this
6719 is fixed by not sending the Channel Key packet immediately but
6720 putting it to queue. However, this is more fundamental problem:
6721 packets that are in queue should actually not be encrypted
6722 because packets that are sent immediately gets encrypted
6723 actually with wrong IV (and thus MAC check fails). So, packets
6724 that are in queue should be encrypted when they are sent to
6725 the wire and not when they put to the queue.
6727 However, the problem is that the current system has not been
6728 designed to work that way. Instead, the packet is encrypted
6729 as soon as possible and left to the queue. The queue is then
6730 just purged into wire. There won't be any fixes for this
6731 any time soon. So, the current semantic for packet sending
6734 o If you send packet to remote host and do not force the send
6735 (the packet will be in queue) then all subsequent packets to the
6736 same remote host must also be put to the queue. Only after the
6737 queue has been purged is it safe again to force the packet
6740 o If you send all packets immediately then it safe to send
6741 any of subsequent packets through the queue, however, after
6742 the first packet is put to queue then any subsequent packets
6743 must also be put to the queue.
6745 Follow these rules and everything works fine.
6747 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6749 * Added new function silc_server_remove_clients_by_server to
6750 remove all client entries from ID list when the server connection
6751 is lost. In this case it is also important to invalidate all
6752 client entires as they hold the invalid server entry. This
6753 fixes fatal bug when server has lost connection and will reconnect
6756 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6758 * Made some sanity checks to silc_server_daemonise like to check
6759 whether the requested user and group actually exists.
6761 * Added sanity check to SKE's silc_ske_responder_finish to check
6762 that the public and private key actually is valid.
6764 * Invalidate the client's nickname when receiving Replace ID
6765 packet and the Client ID is being replaced. This means that the
6766 server will query the nickname if someone needs it (client)
6769 * Sort the ID Cache in client library when the ID Cache data
6770 has changed (needs sorting).
6772 * Do not allow for SILC client to create several connections to
6773 several servers. The client does not support windows right now
6774 and generating multiple connections causes weird behaviour.
6776 Irssi-silc client does support windows and can handle several
6777 connections without problems, see: www.irssi.org and SILC plugin.
6779 * Fixed some places where client was added to the IDList. The
6780 rule of thumb is following (in order to get everything right):
6781 If the client is directly connected local client then the
6782 `connection' argument must be set and `router' argument must be
6783 NULL to silc_idlist_add_client function. If the client is not
6784 directly connected client then the `router' argument must
6785 bet set and the `connection' argument must be NULL to the
6786 silc_idlist_add_client function.
6788 * The funtion silc_server_packet_send_local_channel actually did
6789 not check whether the client was locally connected or not. It
6790 does that now. Fixed a bug related to LEAVE command.
6792 * Fixed Remove Channel User payload parsing bug in server's
6793 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6795 * The server's silc_server_save_channel_key now checks also the
6796 global ID list for the channel as it might not be in the local
6797 list. Fixed a bug related to LEAVE command.
6799 * Is this the end of the [<unknown>] buglet that has been lurking
6800 around for a long time? A little for loop fix in server's
6801 silc_server_command_whois_parse that is used by both IDENTIFY
6802 and WHOIS command. At least, this was a clear bug and a cause
6803 of one type of [<unknown>] buglet.
6805 * WHOIS and IDENTIFY commands call the function
6806 silc_server_command_[whois/identify]_check function even if
6807 we are not router server.
6809 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6811 * Added --with-gmp configuration option. If set the GMP
6812 is always compiled in the SILC source tree. If not set then
6813 it is checked whether the system has the GMP3 installed. If
6814 it has then the GMP won't be compiled (the system's headers
6815 and library is used), if it doesn't have it then the GMP is
6816 compiled in the SILC source tree.
6818 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6820 * Changed RSA private exponent generation to what PKCS #1
6821 suggests. We try to find the smallest possible d by doing
6822 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6823 not security fix but optimization.
6825 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6827 * Added new config entry [Identity] to fork the server and run
6828 it as specific user and group. A patch from Bostik.
6830 * Imported Dotconf configuration library into lib/dotconf.
6831 This will be used to create the SILC configuration files later.
6832 It will appear in the distsribution after this commit.
6834 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * A big code auditing weekend happening. Auditing code for
6837 obvious mistakes, bugs and errors. Also, removing any code
6840 Removed files for being obsolete:
6842 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6843 inline in the file lib/silcutil/silcbuffer.h)
6845 o lib/silcutil/silcbufutil.c (the header has inline versions)
6847 Changed code to fix possible error conditions:
6849 o The buffer formatting routines now check that the destination
6850 buffer really has enough space to add the data. This applies for
6851 both buffer formatting and unformatting
6852 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6853 unformatting was changed to accomodate following rules:
6854 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6855 sent to the function while XXX_*STRING will not allocate or copy
6856 the data into the buffer. Instead it sets the pointer from the
6857 buffer into the pointer sent as argument (XXX_*STRING used to
6858 require that the pointer must be allocated already). This change
6859 makes this whole thing a bit more consistent and more optimized
6860 (note that the data returned in the unformatting with XXX_*STRING
6861 must not be freed now). The routines return now -1 on error.
6863 o Tried to find all code that use buffer_format and buffer_unformat
6864 and added return value checking to prevent formatting and
6865 especially unformatting errors and possible subsequent fatal
6868 o Changed ske->x and ske->KEY to mallocated pointers in
6869 lib/silcske/silcske.h. Fixed possible data and memory leak.
6871 o Added return value checking to all *_parse* functions. Fixed
6872 many memory leaks as well.
6874 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6875 so that buffer overflows would not happen. All code now also
6876 checks the return value as it can fail.
6878 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * Added reconnection support to server if the normal server looses
6881 its connection to the router (for example if router is rebooted).
6882 The server performs normal reconnection strategy implemented
6883 to the server. Affected file silcd/server.c.
6885 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * Added new packet type SILC_PACKET_SET_MODE that is used to
6888 distribute the information about changed modes (for clients,
6889 channels and clients channel modes) to all routers in the
6890 network. Updated the protocol specification accordingly.
6892 Added functions into silcd/packet_send.c and
6893 silcd/packet_receive.c: silc_server_send_set_mode,
6894 silc_server_set_mode.
6896 Added new files silcmode.[ch] into lib/silccore that implements
6897 the encoding and decoding of Set Mode Payload. Added new type
6898 SilcSetModePayload. Moved the definitions of different modes
6899 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6901 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6903 * Oops, a little mistake in server's connection authentication
6904 protocol. The protocol is not ended with FAILURE but with
6905 SUCCESS if the authentication is Ok. :) Affected file is
6908 * Implemented NICK_CHANGE notify handling in server in the file
6909 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6910 the local clients on the channel. After the changing nickname
6911 in router environment snhould work and the [<unknown>] nickname
6912 should appear no more.
6914 The silc_server_replace_id function that receives the Replace ID
6915 payload now sends the NICK_CHANGE notify type also in the file
6916 silcd/packet_receive.c
6918 * Changed WHOIS and IDENTIFY command to support the maximum amount
6919 of arguments defined in protocol specs (3328 arguments). This
6920 fixed a bug that caused problems when there were more than three
6923 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Added extra parameter, command identifier, to the
6926 silc_client_send_command so that explicit command identifier
6929 Changed that ID list routines uses specific command identifier
6930 when sending WHOIS/IDENTIFY requests to the server so that they
6931 can be identified when the reply comes back.
6933 Affected files lib/silcclient/command.[ch],
6934 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6936 * Added `sender' argument to silc_server_packet_send_to_channel
6937 to indicaet the sender who originally sent the packet to us
6938 that we are now re-sending. Ignored if NULL. Affected file
6939 silcd/packet_send.[ch].
6941 * Added some server statistics support in silcd/server_internal.h
6942 SilcServerStatistics structure and around the server code. Also
6943 send some nice statistics information when client is connecting
6946 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * Fixed channel ID decoding in server's JOIN command reply in
6949 silcd/command_reply.c
6951 * Fixed braodcasting of replace ID payload to not to send it if
6952 we are standalone server in silcd/packet_receive.c.
6954 * Fixed all channel message sending routines to not to send
6955 packets to clients that has router set, since they are routed
6956 separately in the same function earlier. Affects file
6957 silcd/packet_send.c and all channel packet sending functions.
6959 * In USERS reply, res_argv[i] are not allocated, the table
6960 is allocated. Thus changed that free the table, not its
6963 * In server's whois_check and identify_check if the client is
6964 locally connected do not send any WHOIS commands - they are not
6967 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6969 * Fixed some minor bugs in client when sending WHOIS command. The
6970 arguments was in wrong order.
6972 * Removed statis function add_to_channel from server in
6973 silcd/command.c that was previously used with the joining but
6976 * Tested USERS command in router environment successfully with two
6977 routers, two servers and two clients.
6979 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6981 * Reorganized the USERS command and command reply in client library
6982 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6983 When the command is given by user we register a pending command
6984 callback that will reprocess the command after the reply has been
6985 received from the server. When reprocessing the packet we then
6986 display the information. Thus, the USERS information is displayed
6987 now in the command callback instead of in the command reply
6988 callback. The processing of the command is same as previously
6989 when server has sent the command reply in the JOINing process.
6991 * Added to USERS command in silcd/command_reply.c to join the client,
6992 we didn't use to know about, to the channel after we've created
6993 a client entry for it. Also, for clienet we did know already still
6994 check whether it is on the channel or not and add it if not.
6996 * Removed silc_server_command_join_notify as the function and its
6999 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7001 * Changed the client's pending command handling to the same as the
7002 server's pending command handling. It is also now possible to
7003 execute command reply functions from other command reply
7004 function as the function callbacks for commands and command
7005 replies are one and same. The pending commands are not static
7006 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7007 in client connection context. Thus, pending commands are server
7008 connection specific as it is convenient.
7010 Changed the function silc_client_command_pending and
7011 silc_client_command_pending_del and added new function
7012 silc_client_command_pending_check. Removed the
7013 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7016 * Added cmd_ident, current command identifier, to the client
7017 connection context in lib/silcclient/client.h to keep track on
7018 command identifiers used in command sending. Client's command reply
7019 function handling now supports the mandatory command identifiers.
7021 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7022 funtions in client to fully support pending command callbacks.
7024 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7025 as one of the arguments to the application in the command reply
7028 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7029 before first releasing SILC but came back. Now it is removed again
7030 and should come back nomore. The FORWARDED flag was used only
7031 by the JOINing procedure by forwarding the command packet to router.
7032 Now, the JOINing procedure has been changed to more generic (due
7033 to various router environment issues) and FORWARDED is not needed
7034 anymore for anything. The protocol specification is yet to be
7037 Now, removed silc_server_packet_forward from server and the flag
7038 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7040 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * Renamed NAMES command to USERS command. The NAMES was named that
7043 due to historical reasons. Now it is renamed. Also, rewrote
7044 parts of the USERS command. The nickname list is not sent anymore
7045 by the server. Only Client ID and mode lists are sent in the USERS
7046 command. Changed this also to the protocol specification.
7048 The client now resolves the names and stuff after it receives
7049 the USERS list from the server when joining to the channel.
7051 * WHOIS and IDENTIFY commands has been changed to support multiple
7052 Client ID's per command. One can now search for multiple users
7053 in the network by sending only one WHOIS or IDENTIFY command.
7054 Changed the code and the protocol specifications.
7056 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7057 uses silc_server_command_whois_parse to parse the request. */
7059 * If normal server, do not parse the WHOIS and IDENTIFY requests
7060 before sending it to the router. Saves some time.
7062 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7064 * Fixed JOIN command on client library. Wrong number of arguments
7065 used to crash the client.
7067 * Added silc_server_channel_has_global function to check whether
7068 channel has global users or not.
7070 * Added silc_server_channel_has_local function to check whether channel
7071 has locally connected clients on the channel.
7073 * The silc_server_remove_from_one_channel now checks whether the
7074 channel has global users or not after given client was removed from
7075 the channel. It also checks whether the channel has local clients
7076 on the channel anymore. If it does not have then the channel entry
7077 is removed as it is not needed anymore.
7079 * The silc_server_notify now checks on JOIN notify whether the joining
7080 client is one of locally connected or global. If it is global then
7081 the channel has now global users on the channel and that is marked
7082 to the channel entry. Also, it now saves the global client to
7083 global list who is joining and JOINs it to the channel. This is
7084 for normal server, that is.
7086 Changed silc_server_send_notify_on_channel,
7087 silc_server_packet_relay_to_channel and
7088 silc_server_packet_send_to_channel check if we are normal server
7089 and client has router set (ie. global client) do not send the
7090 message to that client, as it is already routed to our router.
7092 * Implemented LEAVE notify type handling in silc_server_notify
7095 * Tested LEAVE command in router environment successfully. Tested
7096 with two routers, two servers and two clients.
7100 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7102 * Implemented SIGNOFF notify type handling in silc_server_notify
7105 * silc_server_remove_id now removes the client entry from all channels
7106 it has joined and thusly sends SIGNOFF notify type.
7108 * Rewrote the NAMES list generation in server by removing two excess
7109 loops. The lists are created now inside one loop.
7111 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7113 * silc_server_remove_channel_user checks now also global list
7114 for channel and client.
7116 * silc_server_new_channel_user checks now both local and global
7117 list for channel and client. Fixed a bug in client id decoding.
7118 Used to decode wrong buffer.
7120 * silc_server_channel_message checks now both local and global
7121 list for channel entry.
7123 * Tested channel joining (hence JOIN) in router environment
7124 successfully. Tested with two routers, two servers and two
7127 * Tested channel message sending in router environment successfully.
7129 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7131 * Added silc_server_save_channel_key into server.[ch] to save the
7132 received channel key in Channel Key payload processing. It is
7133 also used in JOIN command reply handling.
7135 Equivalent function silc_client_save_channel_key added into
7136 client.[ch] into client library.
7138 * Changed JOIN command reply to send information whether the channel
7139 was created or not (is existing already) and the channel key
7140 payload. Changed protocol specs accordingly.
7142 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7143 the request was sent by ID and not by nickname. Crashed on
7146 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7148 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7149 now correctly save the received data.
7151 * silc_server_free_sock_user_data now notifies routers in the
7152 network about entities leaving the network.
7154 At the same time implemented functions silc_server_remove_id
7155 and silc_server_send_remove_id to receive and send REMOVE_ID
7156 packets. The packet is used to notify routers in the network
7157 about leaving entities. The ID removed will become invalid in
7160 * Added function silc_idlist_del_server into server. Removes and
7161 free's server entry from ID list.
7163 * silc_server_private_message function now checks, if we are router,
7164 that the destination ID really is valid ID, naturally.
7166 * In router when NEW_ID packet is received (for new client) the
7167 hash of the Client ID is saved in the ID Cache but the
7168 client->nickname is set to NULL, instead of putting the hash
7171 IDENTIFY command now also checks that client->nickname must be
7172 valid. If it is not if will request the data from the server who
7173 owns the client. Added new function
7174 silc_server_command_identify_check.
7176 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7177 to set the command to already allocated Command Payload.
7179 * Tested private message sending in router environment with two
7180 routers, two servers and two clients. Fixed minor bugs and now
7183 * Fixed segfault from client's NAMES command. Used to crash if
7186 * Forwarded packets must not be routed even if it is not destined
7187 to the receiver. Changed server code comply with this.
7189 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7191 * Added `require_reverse_mapping' boolean value to ServerParams
7192 structure. If TRUE (not default) the server will require that
7193 the connecting host has fully qualified domain name.
7195 If the reverse mapping is not required and hostname could not be
7196 found the IP address is used as hostname.
7198 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7200 * Implemented version string checking to both client and server.
7201 The check is incomplete currently due to the abnormal version
7202 strings used in development version of SILC.
7204 * Changed all command functions in server to use the new
7207 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7209 * Changed char *data to unsigned char *data in ID Cache system to
7210 support binary data as ID Cache data. Changed code to support
7211 binary data in lib/silccore/idcache.c.
7213 * Renamed silc_server_packet_relay_command_reply to
7214 silc_server_command_reply as it is normal packet receiving
7215 function. Rewrote the function to accept command replys for
7216 servers and not only for clients.
7218 * Mark remote router always as registered server if we are connecting
7219 to it. Otherwise, commands sent by the router to us are ignored.
7221 * All ID List find routines now returns the ID Cache Entry pointer
7222 as well if requested.
7224 * WHOIS command works now in router environment, tested with two
7225 routers, two servers and two clients.
7227 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7228 in router environment (as it is almost equivalent to WHOIS) but
7229 hasn't been tested thoroughly. Added new functions:
7231 silc_server_command_identify_parse
7232 silc_server_command_identify_send_reply
7233 silc_server_command_identify_from_client
7234 silc_server_command_identify_from_server
7236 * Disabled route cache adding because adding two different ID's with
7237 same IP replaces the old cache entry thus giving wrong route.
7238 The entry->router->connection is always the fastest route anyway
7239 so route cache may not be needed. Of course, new routes maybe
7240 established after receiving the ID when the entry->router->connection
7241 might not be anymore the most optimal.
7243 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7245 * Add route cache for received ID for fast routing.
7247 * Added silc_server_packet_route to route received packet on router
7248 that is not destined to us.
7250 * Renamed silc_server_get_route to silc_server_route_get.
7252 * Added id_string and id_string_len fields into SilcServer to
7253 include encoded ServerID for fast comparing without excess
7254 encoding of the ID's.
7256 * Cleaned up WHOIS command on server side. Added following static
7259 silc_server_command_whois_parse
7260 silc_server_command_whois_check
7261 silc_server_command_whois_send_reply
7262 silc_server_command_whois_from_client
7263 silc_server_command_whois_from_server
7265 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7266 arguments in command replies. All command functions should be
7267 updated to use this macro.
7269 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7271 * Minor typo fixes on command reply handling on server.
7273 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7275 * Added silc_server_command_add_to_channel internal routine to add
7276 the client to the channel after router has created the channel and
7277 sent command reply to the server.
7279 * Added generic silc_server_send_command to send any command from
7282 * Use static buffer with ID rendering instead of duplicating data.
7284 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7286 * Fixed a channel user mode bug when joining to a channel server gave
7287 everybody channel founder rights, oops.
7289 * We mark ourselves as the router of the incoming server connection
7290 if we are router ourselves. This way we can check in some packet
7291 sending functions whether it is locally connected server. For
7292 incoming router connections we put NULL.
7294 * For router sending packets locally means now always sending the
7295 packet cell wide; to local clients and local servers. For normal
7296 server sending packet locally means sending it to only local
7299 * Fixed the JOIN command to really work in router environment. If the
7300 channel is created it is always created by the router. Router is
7301 also responsible of making the initial joining to the channel,
7302 sending JOIN notify to the sending server and distributing
7303 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7304 does not exist server doesn't do anything else but forward the
7305 command to the router which performs everything.
7307 * Added silc_server_send_channel_key function to send the Channel Key
7310 * Added silc_server_create_channel_key to create new channel key. The
7311 channel key is now re-generated everytime someone joins or leaves
7312 a channel, as protocol dictates. Note: channel->key_len is the
7315 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7317 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7318 packet_receive.[ch] to separate packet sending and receiving
7319 routines. The server.[ch] now includes everything else including
7320 actual packet processing (writing and reading data) and other
7323 Renamed silc_server_private_message_send_internal to
7324 silc_server_send_private_message. The routine is still though
7325 used only to relay private messages as server does not send
7326 private messages itself.
7328 Renamed silc_server_new_channel to silc_server_create_new_channel
7329 and added new function sicl_server_new_channel that handles the
7330 incoming New Channel packet. Added also new sending function
7331 silc_server_send_new_channel to send New Channel Payload.
7333 * Added new function silc_server_notify to process incoming notify
7334 packet to the server/router. Server may then relay the notify
7335 to clients if needed.
7337 * Added new function silc_server_new_channel_user to process incoming
7338 New Channel User packet. Router will redistribute the packet and
7339 send JOIN notify to its local clients and locally connected servers
7340 if needed. Normal server will send JOIN notify to its local client
7341 on same channel when received this packet. Added also corresponding
7342 sending function silc_server_send_new_channel_user to sent the
7345 * Added boolean route argument to send_notif_to_channel and
7346 packet_send_to_channel functions to attempt to route the packet
7347 if it is TRUE and send only locally if it is FALSE.
7349 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7351 * silc_server_replace_id now broadcasts the received replace ID
7352 packet if it is not broadcast packet already. The router must
7353 broadcast to inform other routers about changed ID.
7355 * Added backpointer to server's router into SilcServer context in
7356 silcd/server_internal.h.
7358 * Fixed silc_server_packet_broadcast to send correct broadcast
7361 * The channel key is now distributed to the local client as soon
7362 as it is received from the router (in router environment) so that
7363 no other packet may be sent for the channel until client has
7366 * silc_server_remove_channel_user now broadcasts the received
7367 Remove Channel User packet if it is not broadcast packet already.
7368 The router must broadcast to inform other routers about removed
7371 * Added users field into SilcPacketContext that is a reference count
7372 of the context. One can increase the reference count by calling
7373 silc_packet_context_dup which is now changed to just increase the
7374 reference count instead of duplicating the data. The reference
7375 count is decresed by calling silc_packet_context_free that will
7376 free the data after the reference count hits zero.
7378 For now on the packet context and everything allocated into it
7379 (including the raw packet from network) must be freed by calling
7380 the new silc_packet_context_free function. Added also new function
7381 silc_packet_context_alloc that must be used now to allocate the
7382 context. This also means that if a routine is asynchronous from
7383 silc_[client/server]_packet_parse_type the packet context must
7384 be duplicated by calling silc_packet_context_dup. Otherwise it
7385 gets free'd after silc_[client/server]_packet_parse_type returns.
7386 Also, one must remember that if packet is duplicated then its
7387 reference count must be decresed by calling the free function as
7388 many times as it was duplicated.
7390 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7391 from both client and server.
7393 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7395 * Made joining to a channel working in router environment.
7397 * Cleaned up JOIN command on server side and create function
7398 silc_server_command_join_channel internal routine to make the
7401 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7403 * Changed silc_command_pending list to SilcDList. Also, added
7404 `ident' field to SilcServerCommandPending structure to identify
7405 the reply and to call correct callback.
7407 Added silc_server_command_pending_check function to replace the
7408 corresnponding macro. The silc_command_pending list is not
7411 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7412 to set identifier to previously allocated Command Payload. It
7413 is used to set identifier for command when resending Command
7416 * Added silc_command_payload_encode_payload to encode Command
7417 Payload buffer from SilcCommandPayload structure.
7419 * Added silc_argument_payload_encode_payload to encode Argument
7420 payload buffer from SilcArgumentPayload structure.
7422 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7424 * Changed WHOIS command to support router connection on server side.
7425 The whois request is always sent to router unless the server is
7426 standalone server. After server has received the reply from the
7427 router will it send the reply to the client.
7429 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7430 broadcast received broadcast packet. The function is used only
7431 by router. The broadcast packet is always sent to the router's
7434 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7435 render given ID to printable string, for log files for example.
7437 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7439 * Made basic router to router connections working. At least they
7440 can now connect to each other but nothing really works the way
7441 they are supposed - yet.
7443 * Added new initiator token to RouterConnection configuration
7444 file in silcd/serverconfig.[ch]. It is used to tell whether we
7445 are the initiator to the remote router or whether we'll expect
7446 the other end to connect.
7448 * Moved registering of listener task to silc_server_init, hence
7449 the server starts listenning as soon as it is run, even if it
7450 does not have connections to other routers. Let's see how well
7453 * Changed default connection retry timeouts for more suitable in
7456 * Removed cipher and such arguments from silc_idlist_add_client
7457 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7458 Added new function silc_idlist_add_data to add the keys and stuff
7461 * Added SilcIDListData structure and added it to SilcClientEntry
7462 and SilcServerEntry as their first field in the structure. This
7463 way we can explicitly cast the ID entries to the SilcIDListData
7464 structure and get common data for the entries. In past, we had
7465 to first check what type of connection it is and then cast it to
7466 correct ID entry type. Now, we can directly cast the opaque
7467 pointer to the SilcIDListData (no matter what ID entry it actually
7468 is) and get the data needed.
7470 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7472 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7473 in some circumstances even if threre were timeout tasks, though not
7474 IO tasks, but tasks anyway. Now fixed.
7476 * Defined SilcServerConnection structure to hold connection specific
7477 stuff about directly connected servers and routers. The definition
7478 is currently in silcd/server_internal.h. I thought about having
7479 a bit more important role fro this struct but for now it is used
7480 only when connecting to other server (or router actually).
7482 * Added connecting retry support in server when connecting to
7483 router(s). The retry feature implement exponential backoff
7484 algorithm. Also, added SilcServerParams structure to hold default
7485 parameters for server. For now, it include these retry settings
7486 and are hard coded. After server is moded to be as Silc Server
7487 Library this structure will be more important.
7489 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7491 * Changed client librarys channel->clients table to SilcList and
7492 changed code accordingly.
7494 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7496 * Changed client's channel table to SilcList and changed code
7497 accordingly. Also changed SilcChannelClientEntry to include back-
7498 pointer to the channel so that client entry can use that structure
7499 as list as well and we have fast cross-reference to the channel.
7500 This change dramatically decreased the complexity of channel
7501 handling with client entry and vice versa (removed one extra
7502 loop when searching for channel entry from many functions).
7504 * Changed server->sim from table to SilcDList and changed code
7507 * NAMES command can now be used from user interface. It will show
7508 the user list on the channel, neatly.
7510 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7511 Code now saves realname of the user if it becomes available.
7513 * Renamed configure.in to configure.in.pre and made ./prepare
7514 script to automatically add correct version string to
7515 configure.in which it creates from configure.in.pre.
7517 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7519 * NAMES command reply now shows users mode with the nickname when
7522 * Moved silc_client_ch[u]mode[_char] functions from
7523 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7524 place sucks, they are utility functions and should be in some
7527 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7529 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7532 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7536 * Added TRQ (efficient deque and list library) into lib/trq. This is
7537 a very good list library that is currently used in the SILC. Defined
7538 SilcList API over the library because I didn't like the API very
7539 much. See lib/trq/silclist.h for the API and examples of how to
7540 use the API. Fixed various places in the code to use the new
7541 SilcList API. The SilcList is meant for lists that has a structure
7542 already defined as a list. It is not suitable to add just some
7543 context to the list (in TRQ, the context is the list actually).
7545 So, I defined SilcDList that can be used for the purpose where
7546 predefined list structure does not exit. This can be used as
7547 such list. Now some context just can be added to the SilcDList.
7548 Currently this list is not used in the SILC just yet, though there
7549 are a lot places where this can replace dynamically allocated
7550 tables and I will fix these places, later, to use SilcDList.
7551 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7552 and use TRQ internally).
7554 Also fixed some annoying warning messages that the original TRQ
7555 code generated. Also minor changes to TRQ's Makefile.in.
7557 * Added support for querying by Client ID to both WHOIS and
7558 IDENTIFY commands into server, as required by the protocol.
7560 * Removed method function pointers from SilcBuffer structure. They
7561 weren't used to anything and just increased the context size for
7562 no good reason. This change also made silc_buffer_alloc and
7563 silc_buffer_free functions inline functions.
7565 * Disabled command flooding detection support until it's fixed so
7566 that it accepts commands in but does not execute them more than once
7569 * Added silc_net_localhost(), to return local hostname, into
7570 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7571 that must be initialized before calling silc_client_init.
7573 * Added new function: silc_server_send_notify_on_channels to send
7574 notify messages to all channels client has joined. It is assured
7575 that the message is sent only once per client.
7577 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7578 lib/silcutil/silcutil.[ch] as silc_format function. The new
7579 function is generic and is used by server as well, not only by
7580 the logging routines.
7582 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7583 the provided version string was not acceptable. Added new function:
7584 silc_ske_check_version into lib/silcske/silcske.h. The function
7585 must be implemented by the application (client or server) and it
7586 does not reside in the SKE library. The function checks the version
7587 string remote end sent.
7589 * Added back pointers (to opaque context and to SilcSocketConnection)
7590 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7592 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7593 duplicate packet context structure.
7595 * Changed `notify' client operation to send same arguments as client
7596 receives from server except for ID's. ID's are mapped to correct
7597 ID entry and that is returned. Also, if channel entry is not sent
7598 by server but the notify is for channel the channel entry is sent
7599 to application (otherwise application doesn't know that it is for
7600 channel (library gets it from packet's Destination ID)).
7602 * Added silc_client_remove_from_channels into client library to
7603 remove a client from all channels it has joined to. Used when
7604 received SIGNOFF notify from server. Added also new function
7605 silc_client_replace_from_channels to replace old ID entry with
7606 new ID entry on all channels. Used when received NICK_CHANGE
7609 * Fixed ID Cache list handling in silc_idlist_get_client in
7610 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7611 to get (or query) client by ID.
7613 * Updated TODO list.
7615 * Added connection authentication status message defined by the
7616 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7617 support for these into the code in client and server side.
7619 * Added generic function silc_client_send_command to send any command
7620 with variable argument list. Application should use this function
7621 to send commands if the command functions provided by the library
7622 does not suite for the application's user interface needs.
7624 * Added new `failure' client operation. Application is notified about
7625 received failure packet if client is executing a protocol. In this
7626 case the protocol's execution has failed.
7628 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7629 is required by the protocol.
7631 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7632 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7635 * Added status flag to SilcSKE object to indicate realtime status
7636 of the SKE protocol.
7638 * Application receives now exactly same command reply arguments as
7639 the library receives from server. However, if ID is received the
7640 corresponding ID entry is returned to the application (eg. Client
7641 ID is mapped to correct SilcClientEntry entry and that is returned).
7642 Changed command_reply client operation due to this change.
7644 * Changed all ID's in commands and in command replys as ID Payloads.
7645 Change affected both client and server side codes.
7647 All ID's sent in SILC network (with execption of ID's in SILC
7648 Packet header) are sent in ID Payload to support variable length
7651 * Server now notifies nick changes and notifies all clients on
7652 the channels about the new nickname (about the new Client ID,
7655 * Implemented CMODE command to change channel modes. Supports all
7656 channel modes defined by the protocol specs except ban and invite
7657 lists. (Also, private channel key mode is supported but support for
7658 setting private channel key in client is missing, thus, this mode
7659 has no effect on client side (except that server requires that the
7660 client uses private channel key and normal channel traffic does not
7663 Also, invite mode works per se, but INVITE command does not work
7664 yet correctly, so you can set channel as invite only channel but
7665 inviting clients to the channel does not work (it is yet to be
7666 thought what's the best way to do it).
7668 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7669 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7670 Implemented CUMODE command to change user's mode on the channel.
7671 Supports all modes defined by the protocol specs.
7673 * Added NAMES command reply to return users modes on the channel.
7675 * Removed unnecessary and slow ciphers from lib/silccrypt.
7677 * Set SO_KEEPALIVE option to connection sockets by default.
7679 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7681 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7682 redefined the Notify Payload into protocol specs.
7684 * Added silc_id_payload_parse_id to get ID directly from raw
7687 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7689 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7690 accept searching by Client ID as well.
7692 * Added support for LEAVE and SIGNOFF notify types in client library.
7694 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7695 to parse ID Payload from raw data.
7697 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7699 * Added flags parameter into silc_ske_assemble_security_properties
7700 function in lib/silcske/silcske.[ch].
7702 * Changed notify client operation to fit better for notify messages
7703 sent by server. The notify payload received from server is now
7704 passed to the application (after parsing it to SilcNotifyPayload).
7705 It is application's responsibility to retrieve the arguments
7706 from the payload and show the message the way it wants. The message
7707 sent by server is implementation specific.
7709 * Changed public keys to comply with the protocol specification.
7710 Old public keys are not supported anymore and are not compatible.
7712 * Removed nickname from Channel Payload as the latest draft removed
7713 it. The client must resolve the nickname from the NAMES command
7714 reply received when it joined the channel.
7716 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7718 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7720 * Fixed some errors in protocol specification drafts.
7722 * Created lib/silccore/silcnotify.c to implement Notify Payload
7723 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7724 generic payloads described by protocol specifications. The file
7725 includes implementations for ID Payload and Argument Payload.
7727 * Changed Command Payload implementation to use the new Argument
7728 Payload. Changed command_xxxx_payload to command_payload_xxxx
7729 to comply with SILC coding conventions.
7731 * Added suppport for Argument Payload handling in Notify Payload
7732 implementation as protocol requires it. Added the new support
7733 into server and client lib as well.
7735 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7737 * Added support for multiple nicknames on same channel. [n] is
7738 added locally to the nickname if there are more than one same
7739 nicknames on the channel.
7741 * Server now sends all nicknames that matched WHOIS request.
7742 Client also shows the list received from server.
7744 * Added TOPIC command to client side. User can now set and show
7745 current topic on channel.
7747 * Added MOTD command to client and server. Also, server sends the
7748 motd when client connects to the server.
7750 * Changed version strings to comply ISO 8601.
7752 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7754 * Fixed protocol error handling in client library. It should now
7755 cope even if the SKE fails for some reason.
7757 * Made new protocol specification drafts for submitting to IETF.
7759 * Implemented TOPIC command to server in silcd/command.c.
7761 * Added two new notify types into lib/silccore/silcnotify.h:
7762 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7763 notify nickname change and topic setting/change on a channel.
7765 * API change of command_reply operation in client library. The
7766 application gets now the status type received from server as well.
7768 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7770 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7772 * Cras fixed and optimized the packet handling even further and
7773 it should work now. Minor change to the prototype of function
7774 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7776 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7778 * Added new function into lib/silcutil/silcschedule.[ch]:
7779 silc_schedule_with_fd to select() a specified fd. The function
7780 returns after timeout expires or data arrives or goes. The
7781 function is used by packet routines to wait that all data is
7782 received from network.
7784 * Fixed data reading from network in lib/silccore/silcpacket.c.
7785 The code now assures that all data is read from the fd and then
7786 continues packet processing. This was a bug fix since the code
7787 used to drop some data in some circumstances.
7789 * Added new function into lib/silcclient/client.[ch]:
7790 silc_client_start_key_exchange to start key exchange after
7791 connection has been established to server. The code internally
7792 now uses this funtion but its main purpose was to provide it
7793 for applications that perform their own connecting. After
7794 application has created a connection it merely calls this
7795 function to start the key exchange between client and server.
7796 The library takes care of everything else after that.
7798 Updated also lib/silcclient/README to explain the usage of
7801 * Do not send to application information that connection has
7802 been established. Application gets notified it by connect
7805 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7807 * Applied cras's patch to add silc_schedule_one function. The
7808 function runs scheduler once and returns.
7810 * Fixed the scheduler after cras messed it up. The timeout
7811 handling works now as it's supposed to work.
7813 * Added into lib/silccore/ silcnotify.h to include notify
7814 message types support. Changed silc_server_send_notify*
7815 functions, in server.[ch], to support those new notify types.
7816 Added the support for the notify types into client library,
7817 as well. Added new notify client operation into ops.h in
7820 * Changed silc_server_packet_send_to_channel to send normal
7821 packets instead of just channel message packets. The function
7822 is now used to send the notify packets to channels. It is not
7823 used to send channel message packets anymore, as server never
7826 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7827 va_arg()s as it seems to require it nowadays. I guess, if SILC
7828 is compiled with older va_arg() the new code should work anyway.
7830 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7832 * Splitted core library. Core library (lib/silccore) includes
7833 now only SILC protocol specific core (and common) components.
7834 Created new utility library (lib/silcutil) that includes more
7835 generic purpose stuff. The stuff for util library was taken
7836 from the old core library. This was minor and easy split.
7838 * Created SILC Client Library (lib/silcclient) that includes
7839 implementation of the SILC client without user interface. This
7840 was major move from silc/ directory. The code has been changed
7841 so that it is transparent towards the user interface. The
7842 silc/ directory includes now the same user interface as before
7843 and it uses the new client library. Read lib/silcclient/README.
7844 Basicly, the client library performs everything else related
7845 to SILC except user interface handling. Also, configuration
7846 files are considered to be part of user interface and library
7847 does not handle them.
7849 This change also changed a lot of structures, function naming etc.
7850 Most important change was that SilcClientWindow object was
7851 renamed to SilcClientConnection in the client library. Created
7852 also new file lib/silcclient/ops.h. Also added new files
7853 silc/local_command.[ch] and silc/client_ops.[ch].
7855 All these changes were made to make it easier for user interface
7856 designers to create what ever user interface for the SILC client
7859 It is also expected that the server will be moved to lib
7860 directory as well and SILC Server Library will be created;
7861 sometimes in the future.
7863 * Removed Local commands from lib/silccore/silccommand.h as
7864 they are application specific and new client library does not
7865 handle any of those anymore.
7867 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7868 old client implementation in silc/.
7870 * Added support for callback functions in SILC_LOG_* macros.
7871 Application can now set its own callbacks that will be called
7872 instead of using the default functions that will always print
7873 the debug messages to stderr (or stdout). Also, debugging can
7874 now be disabled by setting silc_debug to FALSE and re-enabled by
7875 setting it to TRUE. Note, that logging will still work even
7876 if debugging is disabled.
7878 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7879 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7880 silc_log_reset_debug_callbacks.
7882 * To enable debugging in silc client one must give now -d
7883 option on command line.
7885 * Changed silc_schedule_init to automatically allocate task queues
7886 if they are not allocated before calling it.
7888 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7890 * Added GMP 3.1 into math library.
7892 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7894 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7895 a channel in SILC network. The packet is used by servers and
7896 routers to notify other routers that user has left a channel.
7897 This little feature was missing until now. Added the feature
7898 to protocol specification as well.
7900 Added functions: silc_server_send_remove_channel_user and
7901 silc_server_remove_channel_user into server.[ch].
7903 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7904 lib/silccore/silcpacket.h. However, they are not implemented
7907 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7909 * Fixed joining to a channel and sending channel messages
7910 between server and router. The channel message sending should
7911 now work inside a cell.
7913 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7915 * Fixed the private message sending between server and router.
7916 The private message sending should now work inside a cell.
7918 * Added silc_server_replace_id into server.[ch] to replace
7919 existing ID in the SILC network.
7921 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7922 and silc_idlist_replace_server_id into idlist.[ch] in server.
7924 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7926 * Fixed the server to server connections. Server can again now
7927 connect to router. Router to router connections probably does
7930 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7932 * Added dynamic protocol registering support. Now protocols can
7933 registered and unregistered on the fly. Patch by cras.
7935 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7937 * Added lib/contrib directory to hold routines that some platforms
7938 don't have but are needed by SILC.
7940 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7941 into lin/contrib to provide getopt() and getopt_long() for
7942 those who don't have it.
7944 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7946 * Added AWAY command to client. When away message is set and
7947 client receives a private message packet the client automatically
7948 replies to the sender with the away message.
7950 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7951 bug seemed to be the cause of recent problems when compiling
7954 * Added version detection support to SKE protocol specification
7955 and added the new changes to the SKE implementation as well.
7956 There were other minor changes in the SKE protocol as well.
7958 Many changes in lib/silcske/silcske.[ch] and in
7959 lib/silcske/payload.[ch].
7961 * Added ^U functionality, clear input line. Patch from cras.
7963 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7965 * Mainly small bugfixes on core library. Fixed some debugging
7966 logging and buffer overflow in silclog.c.
7968 * Updated config.sub and config.guess on the distribution tree.
7970 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7972 * Added command lagging support in server. Client may execute
7973 commands now only once in two seconds.
7975 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7977 * Optimized packet reception. MAC computation and checking is now
7978 also more optimized. A lot previously duplicated code is now
7979 used as generic by both client and server.
7981 * Fixed key pair generation in clientutil.c
7983 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7985 * Added into lib/silccore/silcbufutil.[ch] new function;
7986 silc_buffer_realloc.
7988 * Moved generic packet sending/encryption functions to
7989 lib/silccore/silcpacket.[ch] from client and server. Some
7990 rewriting of the functions.
7992 * Moved all generic packet reception/decryption functions to
7993 lib/silccore/silcpacket.[ch] from client and server. The
7994 packet processing is now much cleaner in both client and server.
7995 These were major changes in both client and server.
7997 * Created many common functions in server to do packet sending.
7998 Previously code were duplicated a lot, this has been removed
8001 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8003 * Rewrote major parts of the ID cache system. Don't know
8004 whether it is better now or not but at least the API is more
8007 * Major rewrite on ID cache stuff on client because of the ID
8008 cache API changes. Added idlist.c to client.
8010 * Also major rewrite on ID cache stuff on server as well.
8011 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8012 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8013 in hand, instead they are all put into the ID cache system now.
8014 All server_idlist_* routines uses ID cache now instead of
8015 traversing its own lists (those lists does not exist anymore).
8016 SilcIDList though still exists. Also, SilcXXXEntry's are
8019 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8021 * Finally made the SKE implementation compliant to the protocol
8022 specification. All mp integers are now binary encoded as
8023 opposed being HEX encoded.
8025 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8028 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8029 functions: silc_[encode/decode]_pem. Also added function
8030 silc_encode_pem_file to PEM encode with newlines ('\n') for
8033 * SILC public keys are now encoded either PEM or binary. Same
8034 option is for private keys as well. By default private keys
8035 are binary encoded and public keys PEM encoded. Silly HEX
8036 encoding were removed.
8038 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8039 function to create fingerprints.
8041 * Fixed a bug in SHA1; does not change the original data anymore.
8043 * Partly implemented INFO command on client and server side.
8044 Fixed CLEAR command. Changes to SERVER command; show current
8045 server(s) when giving command without arguments. Added
8046 VERSION command to client.
8048 * Added check to server that unregistered connections cannot
8049 execute commands (unless it is specificly allowed).
8051 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8053 * Fixed screen refresh.
8055 * Fixed channel joining bug from client. On some circumstances
8056 client tried to join to a channel it had already joined.
8058 * Added public key verification process into client's protocol.c.
8059 The client now verifies the public key from user and saves
8060 it into ~./silc/serverkeys/ directory.
8062 Added into: clientutil.[ch]: silc_client_verify_server_key.
8064 * Changed SKE protocol's silc_ske_initiator_finish function
8065 to accept callback function that verifies the received public
8066 key. Removed old silc_ske_verify_public_key function.
8068 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8070 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8071 silc_pkcs_private_key[_data]_set.
8073 * Made the password and public authentication more cleaner in
8074 server's protocol.c.
8076 * Removed historic and obsolete protocol `channel_auth' from
8077 both client and server.
8079 * Removed wrong way of sending command status messages from
8080 server to client in server's command.c. The old way violated
8081 protocol specification.
8083 Changes to silccore/silccommand.[ch]: removed
8084 silc_command_encode_status_payload -> not needed anymore,
8085 changed silc_command_encode_payload_va to accept extra
8086 argument on variable argument list. The argument type must
8087 now be provided to the function. Also, added new function:
8088 silc_command_encode_reply_payload_va which is same as
8089 normal command_encode_payload_va except command status type
8090 is provided as extra argument.
8092 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8094 * Added ~./silc directory handling. The directory includes the
8095 public and private keys for the client.
8097 Added silc_client_check_silc_dir, silc_client_create_identifier
8098 and silc_client_load_keys.
8100 * Implemented SILC protocol compliant public key. Added public
8101 and private key saving to and loading from files.
8103 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8104 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8105 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8106 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8107 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8109 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8110 silc_pkcs_load_[public/private]_key.
8112 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8114 * Added silc_server_get_route (route.[ch]) to get connection
8115 data for the fastest route for given ID.
8117 * Implemented INVITE command on client and server. The command
8118 were re-defined in the SILC Protocol Specification and the
8119 implementation now complies with the specification.
8121 * Implemented PING command on client and server.
8123 * Implemented NAMES command on client and server. The server side
8124 supports currently only normal server not router server yet.
8125 Some changes to NAMES definition in SILC protocol specification.
8127 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8129 * Implemented LEAVE command on client and server.
8131 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8132 again. This change was made to the protocol as well. Server
8133 should not violate the protocol specification anymore.
8135 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8137 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8138 was tested. SOCKS4 was not but should work anyway.
