7 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
9 * Changed the UMODE's mode mask argument to be optional. If
10 not provided then the command merely returns the current mode
11 mask to the client. Updated protocol specs and the server.
12 Affected file is silcd/command.c.
14 * Added SILC session detachment/resuming support. It is possible
15 to detach by closing the network connection and then re-connect
16 and resume to the old client session. Added DETACHED user
17 mode that server will set for detached client. Added new
18 packet RESUME_CLIENT which is used to perform the resuming
19 process. Added DETACH command. Updated the protocol specs,
20 core library, client and server. Protocol TODO #22. Very
21 many affected files around the tree.
23 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
25 * Changed the CMODE's mode mask argument to be optional. If
26 not provided then the command merely returns the current mode
27 mask to the client. Updated protocol specs and the server.
28 Affected file is silcd/command.c.
30 * Changed the Killer's Client ID in KILLED notify to be just
31 any ID payload since router server is allowed to kill as well.
32 Updated protocol specs, client libary and server. Affected
33 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
34 and irssi/src/silc/core/client_ops.c.
36 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
38 * Added new user modes ANONYMOUS for special anonymous servers
39 that may set the mode for client, and BLOCK_PRIVMSG which
40 client may set to block incoming private messages unless the
41 Private Message Key flag is set (using private keys to protect
42 private messages). Updated protocol specs and code in client
43 and server and core library. Protocol TODO #23. Affected
44 files are lib/silccore/silcmode.h, silcd/server.[ch],

46 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
48 * Added new channel user mode BLOCK_MESSAGES which the client
49 may set to itself to tell server not send channel messages.
50 Other packets such as channel key packets are still sent.
51 Protocol TODO #23. Updated the protocol specs, client and
52 server. Affected files are lib/silccore/silcmode.h,
53 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
54 lib/silcutil/silcutil.c, silcd/command.c, and
57 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
59 * Redefined the Status Payload to include now two 8 bit fields,
60 instead of one 16 bit field. This now makes it possible to
61 send list of errors. Updated the protocol specs and the code
62 in core library, client library and server. Protocol TODO #1.
63 Affected files are lib/silccore/silccommand.[ch],
64 lib/silcclient/command_reply.[ch], silcd/command.c,
65 silcd/command_reply.c and silcd/packet_receive.[ch].
67 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
69 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
70 must be handled by the application and should tell the application
71 that an error message was already printed, and it should print the
72 config coords (line, filename, ...). Affected files are
73 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
75 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
76 server config parsing code more readable.
78 Fixed a bug in the fetch_logging() config callback.

94 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
96 * Added STATS command to the protocol after all, to return
97 various statistical information about the network. It can
98 be used by clients to retrieve statistical information, and
99 servers may use it to to fetch cell and network wide
100 statistics from router. Updated the protocol specs and
101 implemented it to the server. Protocol TODO #16.
102 Affected files are lib/silccore/silccommand, silcd/command.[ch],
103 silcd/command_reply.[ch].
105 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
107 * The LIST command reply in client libary now adds new channel
108 entry if the returned channel doesn't exist yet in cache,
109 and returns the channel entry to the application in the
110 command_reply client operation. Affected file is
111 lib/silcclient/command_reply.c.
113 * Changed the channel message payload's MAC generation to
114 include the IV in the MAC as well. This way all relevant
115 parts of the channel message payload are authenticated also
116 with the channel message MAC (and not only by packet MAC).
117 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
118 Affected file is lib/silccore/silcchannel.c.
120 * Fixed the SKE to save the remote version, since the
121 silc_ske_parse_version mistakenly checked wrong version,
122 after it replaced the start payload. Affected files are
123 lib/silcske/silcske.[ch].
125 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

130 Affected files lib/silcutil/silcstrutil.[ch].
132 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
133 files are lib/silcutil/silcstrutil.[ch].
135 * Defined that the security property fields in SKE SHOULD be
136 UTF-8 encoded, defined that version string MUST be US-ASCII
137 encoded, defined that passphrases sent in connection
138 authentication protocol MUST be UTF-8 encoded. Implemented
139 these to the client and server. Defined also that other
140 passphrases sent in the protocol MUST be UTF-8 encoded.
141 Affected files are lib/silcske/silcske.c,
142 lib/silcclient/protocol.c, silcd/protocol.c,
143 silcd/serverconfig.c, and lib/silccore/silcauth.c.
145 * Changed the silc_client_close_connection interface to not
146 need the SilcSocketConnection which should not be visible
147 to application. Affected files are lib/silcclient/client.c
148 and lib/silcclient/silcclient.h.
150 * Rewrote the text for Private Message Key Payload in the
151 protocol specification. Protocol TODO #11.
153 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
155 * Upgraded the protocol version to 1.1, updated protocol specs
158 * Added the nickname as new argument to NICK_CHANGE notify and

166 Protocol TODO #13. Affected files are silcd/command.c,
167 silcd/packet_receive.c, packet_send.[ch],
168 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
169 The killer's client entry is now returned to application in
170 the `notify' client operation.
172 * Fixed the Max Argument fields that had too large value set
173 in the protocol specs. Protocol TODO #14.
175 * Added the LEAVE command reply to return the ID of parted
176 channel. Updated protocol specs and implemented it to the
177 client and server. Protocol TODO #15. Affected files are
178 silcd/command.c, lib/silcclient/command_reply.c. The channel
179 entry is now returned to application in the `command_reply'
182 * Rewrote the version SKE version checking in client libary
183 and in server to use the silc_parse_version_string. Affected
184 files are lib/silcclient/protocol.c, silcd/protocol.c.
186 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
187 commands that was missing it, and updated protocol specs and
188 the server implementation. Protocol TODO #10. The affected
189 file is silcd/command.c.
191 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
192 generic reply to a generic request (REQUEST flag), and
193 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
194 way. A draft-riikonen-silc-flags-payloads-00.txt is written
195 to define the payload for DATA flag. Added the flags to
196 the implementation. Protocol TODO #9. Affected file is
197 lib/silccore/silcchannel.h.
199 Changed the client library to return the message length
200 to application as well in the channel_message and private_message
201 client operations. Affected files are
202 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
203 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
204 and lib/silcclient/client_ops_example.c.
206 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
207 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
208 the channel. Updated protocol specs and impelemented this
209 to client and server. Protocol TODO #6. Affected files are
210 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

213 Added new options m and M to CMODE command in Irssi SILC
214 client to set these modes.
216 * Deprecated all administrative commands from SILC protocol
217 since they are highly implementation specific commands.
218 Updated protocol specs. Moved the old commands in
219 implementations to private range of command types. Affected
220 files are silcd/command.c, lib/silcclient/command.c and
221 lib/silcclient/command_reply.c. Protocol TODO #8.
223 * Fixed a bug in server where sending unknown command crashes
224 the server. Affected file silcd/command.c.
226 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
228 * Added SILC_PROTOCOLVERSION macro to check protocol version
229 of a socket connection. The affected file is
230 lib/silcutil/silcsockconn.h.

239 Affected file silcd/protocol.c.
241 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
243 * Some client implementations quit network by doing first LEAVE
244 and then immediately SIGNOFF (like Bombyx). We now do check
245 after a short time after LEAVE notify and check whether the
246 client is still valid after LEAVE, and if not we remove it from
247 cache. Affected file is lib/silcclient/client_notify.c.
249 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
251 * Merged version 1.1.4 of zlib. Even if it not currently in use,
252 it's good not to have security holes here.
254 * Fixed a negative refcount situtuation for the config context.
255 Affected file is silcd/serverconfig.c.
257 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
259 * ROBOdoc documented lib/silcutil/silcutil.h.
261 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>

264 totally saved 16 bytes of memory per context after optimization.
265 Affected files are lib/silccore/silcpacket.[ch].
267 * Made strict checks for valid SILC IDs. Affected file is
268 lib/silccore/silcid.c.

275 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
277 * Changed the silc_get_username and silc_get_real_name to
278 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
280 * Fixed the Irssi SILC Client to use the silc_get_username and
281 silc_get_real_name insted of glib routines since the glib
282 routines only corrupt stack. Fixes the Irssi SILC to work in
283 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
285 * Fixed the Irssi to not use g_get_home_dir since it crashes
286 or returns garbage on cygwin and corrupts stack. Added function
287 get_home_dir to Irssi routines. Affected files are
288 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
290 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
292 * Made some structure optimizations. SFTP memory FS MemFSEntry
293 entry structure. Optimized SilcTask structure. Optimized
294 SilcPacketContext structure.
296 Affected files lib/silcsftp/sftp_fs_memory.c,
297 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
299 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
301 * And yet again reverted back the config thing since Johnny
302 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
305 * Fixed memory leaks from config object. Affected files are
306 silcd/serverconfig.[ch].
308 * Added support for adding new connections to the server in rehash.
309 After rehash they take effect.
311 Added support for changing the maximum allowed connections in
312 rehash. The number can grow but going smaller is not supported.
314 Added function silc_server_num_sockets_by_remote to the
315 silcd/server_util.[ch].
317 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
319 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
321 * Added preliminary checking during config parsing for a valid
322 public/private key and removed further checks in the code.
323 Affected files are silcd/serverconfig.[ch], server.c.
325 * Moved functions silc_server_drop() and silc_server_daemonise()
326 from server.c to silcd.c since they are stricly related to
327 the application activity.
329 * Reverted a small part of the automatic ref/unref since
330 it caused a double unref in some situations. Affected
331 files are silcd/silcd.[ch], server.c, serverconfig.c.
333 * Added some .cvsignore files in the lib directory.
335 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
337 * Fixed silc_net_gethostbyaddr to correctly resolve by
338 address. Affected file lib/silcutil/silcnet.c.
340 * Fixed the notify relaying to client. The HMAC to be used
341 with relayed packets ws wrong and caused decryption failure
342 at the client end. Affected file is silcd/packet_receive.c.
344 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
346 * Created new branch silc_protocol_1_0_branch.
348 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
350 * Changed the silc_server_config_* routines to be SilcServer
351 independent. They are now officially application specific code
352 and not part of generic server implementation. Affected files
353 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
355 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
357 * Added automatic referencing of config context in the
358 silc_server_config_alloc, and automatic unreferencing in the
359 silc_server_config_destroy. Affected files are
360 silcd/serverconfig.[ch], silcd/silcd.c.
362 * Fixed the silc_log_quick handling in the logging routines.
363 It didn't log quickly when it was TRUE. Affected file is
364 lib/silcutil/silclog.c. Also the flush delay was set even
365 if it was 0 in config file. Affected file is
366 silcd/serverconfig.c.
368 * Added support for changing key pair of the server in rehash.
369 Affected file silcd/server.c.
371 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
373 * Fixed the TOPIC_SET notify to not cras. It changed the topic
374 too early, before getting the channel entry. Affected file
375 is silcd/packet_receive.c.
377 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
379 * Added functions silc_server_config_[ref/unref], these are used
380 to prevent that the config object is destroyed.
382 No longer directly affect global variables silc_log_quick and
383 silc_log_delay, they are first cached inside the config object
384 and then applied with silc_server_config_setlogfiles().
386 silc_server_config_set_defaults() is now internal to
387 serverconfig.c, there are no reasons to show this internal stuff
390 Affected files are silcd/serverconfig.[ch].
392 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
393 fprintf's to stderr, since some code may be executed again after
394 the server went into the background. Affected files are
397 * Added rehash support. Added function silc_server_rehash() that
398 will perform all the basic tasks of the rehashing procedure.
400 * Added command line option `-x, --hexdump'. This will enable the
401 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
402 The option `--hexdump' implies `--debug'.
404 * Fixed a bad bug in the logging APIs (silcutil library) where
405 the application would crash after calling silc_log_reset_all().
407 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
409 * Fixed the KICKED notify handling in client library to
410 correctly remove the channel and all entries from the
411 channel when I was kicked. This bug crashed the client.
413 Fixed yet another but in KICKED notify handling to remove
414 the kicked client correctly from the channel.
416 Affected file is lib/silcclient/client_notify.c.
418 * Fixed a minor bug in looking up correct client entry
419 in KICKED notify in server. Affected file is
420 silcd/packet_receive.c.
422 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
423 sources correctly to distribution. Fixes --with-gmp option.
425 * Removed the manual rehashing from ID Cache, and changed it
426 to use the SILC Hash Table's auto rehash feature. Affected
427 file is lib/silccore/silcidcache.c.
429 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
431 * Fixed a bug in the silc_client_nickname_format function that
432 handles the multiple same nickname formatting. Two clients
433 with same nickname caused problems after the first one left
434 and rejoined. It didn't format the nickname correctly.
435 Affected file is lib/silcclient/idlist.c.
437 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
439 * Don't change the topic if olod topic is same as new one.
440 Affected file is silcd/packet_receive.c.
442 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
444 * Added cross-reference support to the SILC Documentation
445 generator. All types across all HTML files are now cross-
446 referenced. Affected files util/robodoc/generator.c and
447 scripts/silcdoc/silcdoc.
449 * Added file lib/silcutil/silctypes.h to include all the
450 arithmetic type definitions and some macros. Removed
451 includes/bitmove.h and moved macros to silctypes.h.
453 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
455 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

460 now returns the type of the ID to the sent pointer. Affected
461 file is lib/silccore/silcid.[ch].
463 * Added check for CMODE_CHANGE notify type that mode change is
464 allowed by the sender. Affected file silcd/packet_receive.c.
466 * Added check for CUMODE_CHANGE notify type that mode change is
467 allowed by the sender. Affected file silcd/packet_receive.c.
468 Added the ID type as CUMODE_CHANGE notify type as argument
469 to the `notify' client operation. Affected files are
470 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
472 * Added function silc_client_add_server to the client library.
473 Added support for resolving also channel and server info when
474 received unknown entity in notify packet. Affected files are
475 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
477 * Added function silc_command_get_status to return the command
478 status from the command reply's argument payload. Affected files
479 are lib/silccore/silccommand.[ch].
481 * Added check for KICKED notify type that the kicking is
482 allowed by the client. Affected file silcd/packet_receive.c.
484 * Created function silc_get_input which can be used to get input
485 (echo on or off) from user on command line. Affected files are
486 lib/silcutil/silcutil.[ch].
488 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
490 * Optimized silc_server_packet_relay_to_channel function.
491 Added new function silc_channel_message_payload_encrypt which
492 can be called directly if channel message payload needs to
493 be encrypted and is already encoded (no need to call _encode
494 function). Packet relaying is now done by router without any
495 extra memory allocations. Affected files are
496 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
499 * Fixed the INVITE notify handling. It took wrong arguments

517 by the client. Affected files are silcd/server_util.[ch],
518 silcd/packet_receive.c and silcd/command.c.
520 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
522 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
523 ID length. It ignored that ID can be IPv6 based as well.
524 Affected file lib/silccore/silcpacket.h.
526 * Fixed the silc_id_id2str and silc_id_str2id to take the
527 IPv6 address offset's into consideration. Affecte file is
528 lib/silccore/silcid.c.
530 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
532 * Fixed the internal Unix scheduler functions to check for
533 NULL context they may receive. The affected file is
534 lib/silcutil/unix/silcunixschedule.c.
536 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
538 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
539 can specify different directory with --home command line
540 parameter. Affected files irssi/src/silc/core/client_ops.c,
543 * SILC-specific commands aren't now executed if the active server
544 isn't of SILC-type, so there won't be problems with having
545 IRC and SILC protocol support in same client. Affected files
546 irssi/src/silc/core/silc-channels.c, silc-servers.c,
549 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
551 * Improved the signal support in SILC Schedule. Added new
552 function silc_schedule_signal_call which is used by application
553 to mark a signal to be called. It is now safe to perform
554 any kind of tasks in signal callbacks since it is guaranteed
555 that the application specified signal callback is called
556 after the signal is over. Affected files are
557 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
559 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
561 * Added `name' field to SilcChannelPrivateKey to represent
562 application given name for the key. Moved also the context from
563 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
564 Added the `name' argument also to the function
565 silc_client_add_channel_private_key.
567 Added function silc_client_current_channel_private_key to set the
568 current channel private key in use.
570 Added "change" command to KEY command which can be used to change
571 the current channel private key. Bound the command also to
574 Also affected files lib/silcclient/client_channel.c,
575 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
577 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
579 * Added silc_rng_get_byte_fast function in to the
580 lib/silccrypt/silcrng.[ch].
582 * Changed the interface of silc_packet_assemble and the
583 silc_packet_send_prepare. If silc_packet_assmble is now
584 called the application does not call silc_packet_send_prepare
585 because the library will call it automatically. These
586 interfaces now also return a reference to the outgoing buffer
587 which includes the assembled packet, which the application can
588 use to encrypt the packet.
590 Affected files are lib/silccore/silcpacket.[ch],
591 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
592 silcd/packet_send.c, server_backup.c and packet_receive.c.
594 * Fixed a packet sending bug on very high load, where outgoing
595 packet queue wasn't handled correctly and packets got corrupted.
596 Affected files are lib/silcutil/*/silc*sockconn.c,
597 lib/silcclient/client.c and silcd/server.c.
599 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
601 * Added macro SILC_PACKET_DATALEN which can be used during
602 packet assembling to check whether the data to be added to
603 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
604 len is truncated until it fits it.
606 Added checks for maximum length of channel message payload and
607 private message payload also.
609 Added checks for maximum packet length in server and in
612 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
613 lib/silcclient/client.c, lib/silccore/silcchannel.c and
614 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
615 lib/silcclient/client_prvmsg.c.
617 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
619 * Added silc_server_packet_queue_purge call to the
620 silc_server_disconnect_remote to assure that all data in the
621 queue before disconnecting is sent to the network. Affected
624 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
626 * Added the deleting of server's own ID cache entry to the
627 silc_server_free function. Free also everything else that
628 has been allocated in silc_server_init. The affected file
631 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
633 * Added functions silc_parse_version_string, silc_version_to_num,
634 and silc_ske_parse_version to parse SILC protocol style version
635 strings. Affected files lib/silcutil/silcutil.[ch] and
636 lib/silcske/silcske.[ch].
638 * Added new configuration params: version_protocol, version_software
639 and version_software_vendor to specify what version the remote
640 host must at least be to be able to connect to server. The vendor
641 string can be regex matched too. Added new function
642 silc_server_connection_allowed to check maximum number of allowed
643 connections, and allowed versions for incoming connections.
644 Affected files are silcd/server.c, server_util.[ch] and
647 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
649 * Added preliminary support for signals in scheduler. The
650 signals we care about are now blocked always when the scheduler
651 is locked. This way we can synchronise the use of signal with
652 scheduler. It is guaranteed that when signal occurs the scheduler
653 is not locked, and thus new tasks can be safely added to the
656 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
657 to silc_schedule_internal_init and silc_schedule_internal_uninit.
658 Added new platform specific routines
659 silc_schedule_internal_signals_[un]block and
660 silc_schedule_internal_signal_[un]register.
662 Added new functions to SILC Schedule API:
663 silc_schedule_signal_[un]register. Each signal that application
664 is going to use should be registered to the scheduler.
666 Affected files are lib/silcutil/silcschedule.[ch],
667 lib/silcutil/*/silc*schedule.c.
669 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
671 * Check for unauthenticated client and server in the
672 silc_server_new_client and silc_server_new_server functions.
673 Affected file silcd/packet_receive.c.
675 * Added function silc_string_is_ascii to check whether given
676 string is 7-bit ASCII string. Affected files are
677 lib/silcutil/silcutil.[ch].
679 * Added function silc_id_is_valid_server_id into the
680 silcd/serverid.c and added checking for valid Server ID's in
681 silc_server_new_server. The Server ID must always be based
682 on the server's public IP address.
684 * Added logging of DISCONNECT packet message in the server.
685 Affected file silcd/server.c.
687 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
689 * Changed all library interfaces that use Global RNG to also
690 accept SilcRng as argument. Affected files are
691 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
692 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
693 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
694 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
697 * Added function silc_pkcs_generate_key to the
698 lib/silccrypt/silcpkcs.[ch] for applications so that they
699 don't need to do pkcs->pkcs->init calls anymore.
701 * Remove SilcSocketConnection from the SFTP API since it really
702 wasn't needed there. The application has the information
703 saved in its contexts anyway and the SFTP layer doesn't need
704 know about it. Affected files lib/silcsft/silcsftp.h and
705 lib/silcsftp/sftp_[server/client].c.
707 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
708 The SilcSimContext is not SilcSim.
710 * Fixed possible buffer overflows in silc_id_render in the
711 lib/silcutil/silcutil.c.
713 * On EPOC the global crypto module lists are not used at all
714 in the crypto library. Added support for using the constant
715 algorithm list on EPOC. Affected files are
716 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
719 * Fixed the handling of third parameter of KICKED notify, since
720 it was mistakenly updated to SILC Protocol 1.0 even though it
721 is to be included in 1.1. Since it is not in 1.0 it is not
722 mandatory, and this fix now handles it only if it is provided,
723 and it is not error if it is not provided. Affected file
724 lib/silcclient/client_notify.c.
726 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
728 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
729 client. Affected file irssi/src/silc/core/client_ops.c.
731 * Merged with Irssi 0.8.4 from irssi.org CVS.
733 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
735 * Check for valid socket connection in client entries before
736 sending any messages. Fixes a crash, but doesn't fix some
737 other underlaying bug that is lurking there. Affected
738 file silcd/packet_send.c.
740 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
742 * $usermode, $cumode and $cumode_space expandos shouldn't do
743 anything with non-SILC server records. Affected file
744 irssi/src/silc/core/silc-expandos.c
746 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
748 * Fixed the silc_net_check_[host/local]_by_sock to support
749 IPv6 bound sockets as well. Now they can return IPv6 addresses
750 as well. Affected file lib/silcutil/silcnet.c.
752 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
753 Affected lib/silcutil/unix/silcunixnet.c.
755 * Fixed ID rendering (at least on some platforms, not NetBSD)
756 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
758 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
760 * Added silc_hash_public_key and silc_hash_public_key_compare
761 functions to be used with SilcHashTable. They can be used to
762 hash public keys and compare public keys in hash table. Affected
763 file lib/silcutil/silcutil.[ch].
765 * Added support for specifying multiple public keys for Client
766 connection section in server configuration file. This makes it
767 possible to accept multiple public keys from same host, or to
768 make a section that accepts any incoming host, and have the
769 accepted public keys listed in the section.
771 Added functions silc_sever_[find/get]_public_key, added the
772 support for this actually to all connection sections but only
773 the Client section is currently allowed to specify multiple
776 Affected files are silcd/server.c, server_internal.h,
777 command.c, protocol.c, server_util.[ch], packet_receive.c.
779 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
781 * Merged Irssi 0.8.2 from irssi.org CVS.
783 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
785 * If silc_debug is TRUE, also output standard logging messages
786 to stderr with the debug output.
788 Made silc_log_reset_all() flushing all channels before returning.
789 Also fixed some documentation typos.
791 Affected files are lib/silcutil/silclog.[ch].
793 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
795 * Fixed the server to check correctly the amount of connections
796 from single host, by checking also the type of the connection.
797 Fixed also the comparison of number of connections and number
798 of allowed connections. Affected files are silcd/server.c,
801 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
803 * Fixed the USERS command reply to save the user's mode on the
804 channel as well. Fixed JOIN command reply to check whether a
805 client is on channel already and not join it twice. Affected
806 file lib/silcclient/command_reply.c.
808 * Added new file silc-expandos.c into irssi/silc/core/ to return
809 various stuff for various signal for the statusbar etc. updating.
810 Now Irssi SILC client prints channel user modes etc. on the
813 * The user mode (like server/router operator changes) is now shown
814 on the Irssi SILC client's statusbar. The affected files are
815 irssi/src/silc/core/client_ops.c, silc-expandos.c.
817 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
819 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
820 to SILC_SCHEDULE_[UN]LOCK macros.
822 * Added more error printing to logs in server code. Affected
823 files silcd/server.c and silcd/protocol.c.
825 * Fixed -S option parsing in Irssi SILC Client. Affected file
826 irssi/src/silc/core/silc-core.c.
828 * Added silc_buffer_alloc_size function. Affected file is
829 lib/silcutil/silcbuffer.h.
831 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
833 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
834 constants. Affected files in
835 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
838 * Changed the internal SFTP Memory FS table to const. Affected
839 file lib/silcsftp/sftp_fs_memory.c.
841 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
843 * Fixed the buffer formatting and unformatting routines to
844 check the size of 64 bits types with sizeof(). Affected
845 file is lib/silcutil/silcbuffmt.c.
847 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
849 * Removed 0.6.x backwards support.
851 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
853 * Changed all integer type names:
854 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
855 to avoid collisions with other libraries using same type names
858 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
860 * Added `prefer_ipv6' argument to the functions
861 silc_net_gethostbyname[_async]. If it is TRUE it will return
862 IPv6 address over IPv4. If FALSE IPv4 address is returned
863 even if IPv6 address was found. Affected files
864 lib/silcutil/silcnet.[ch].
866 * Added support silc_net_create_connection[_async] to fallback
867 to IPv4 address if IPv6 address could not be used (like if
868 it doesn't work on a specific system). Affected file in
869 lib/silcutil/unix/silcunixnet.c.
871 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
873 * Added silc_schedule_reinit function to do the enlarging
874 of the max tasks handling capabilities of the scheduler.
875 Affected files lib/silcutil/silcschedule.[ch].
877 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
879 * Added automatic extern "C" { ... } for C++ compilers so the
880 application does not need to define them. Affected file
881 includes/silcincludes.h.
883 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
884 old name went against naming convention. Applications now
885 include "silcclient.h" instead of "clientlibincludes.h".
886 Removed includes/clientlibincludes.h, it is redundant now.
888 * Renamed includes/version.h to silcversion.h.
890 * Added really preliminary support for OS/2 into the util
891 library. Only thread & mutex API is implemented, others
892 are still to be implemented. Created the lib/silcutil/os2/
893 directory. Created also file includes/silcos2.h.
895 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
897 * Added preliminary BeOS support into the util library.
898 Created lib/silcutil/beos/, and implemented all the needed
899 functions to support SILC on BeOS. Created also file
902 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
904 * Added proper initializations to silc's irssi code, so it's
905 now possible to load it as module. Affected files
906 irssi/src/silc/core/silc-core.c,
907 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
909 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
911 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
914 * Fixed the silcdoc document generator to correct generate
915 docs from all kinds of filenames. Affected files are
916 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
918 * ROBOdoc documented lib/silcutil/silcmemory.h.
919 Added also new function silc_memdup.
921 * Removed lib/silcutil/silcbufutil.h and moved those routines
922 to the lib/silcutil/silcbuffer.h.
924 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
926 * Added `user_count' to the SilcChannelEntry which now tells the
927 number of users on the channel. The user count is now saved
928 in normal server of global channels as well. Affected files
929 silcd/server.c, idlist.h, packet_receive.c and command.c.
931 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
932 include file utility functions.
934 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
935 instead of calling directly OS routines.
937 * Fixed NICK change printing in Irssi SILC Client. Fixed
938 KICKED notify printing in Irssi SILC Client. Affected file
939 irssi/src/silc/core/client_ops.c.
941 * Fixed a NICK change bug in client library, to not recreate the
942 client_entry->channels hash table everytime nick is changed.
943 Affected file lib/silcclient/client.c.
945 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
947 * ROBOdoc documented the lib/silcske/silcske.h, and improved
948 the SKE interface a bit.
950 * Fixed padding problem in PKCS#1. The padding was not actually
951 random since the random number generator was used incorrectly.
952 This security bug affects only when encrypting with PKCS#1, and
953 it is not currently used at all in SILC. SILC only use signing
954 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
956 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
958 * Rewrote the notify handling in Irssi SILC client to not call
959 the events as signals. Fixes problems with Perl support.
960 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
962 * Send the auto-nicking NICK command in client library with
963 little timeout after connecting. The affected file is
964 lib/silcclient/client.c.
966 * Added following new config file settings:
967 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
968 key_exchange_timeout, conn_auth_timeout, connections_max,
971 Implemented all the new config settings handling in the server.
973 Optimized the use of SKE Mutual flag usage. Use it only
974 if connection authentication protocol is not based in public
977 Renamed all SilcServerConfigSection* to SilcServerConfig*
978 to have a bit shorter names.
980 Affected files silcd/serverconfig.[ch], server.[ch], and
983 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
985 * Cleaned up the listening sockets code, preparing for the rehash
986 support. Affected file is silcd/server.c.
988 * Fixed some output messages. Affected files are silcd/silcd.c,
991 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
993 * Create lib/doc/silcrng_intro.html document as introduction
994 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
996 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
998 * Fixes to the silcd config template. Affected file is
999 doc/example_silcd.conf.in.
1001 * Removed type casts from silc_calloc(), conforming to the
1002 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1004 * Removed param_name member from client, server, and router
1005 section structs, now identifying the param directly.
1007 Added CONFIG_FREE_AUTH macro in config file parsing.
1009 Affected files are silcd/serverconfig.[ch].
1011 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1013 * Fixed command line parameter handling. All SILC initialization
1014 is now done in silc_core_init() which also fixes autoconnecting
1017 Affected files irssi/src/silc/core/silc-core.c,
1018 irssi/src/fe-text/silc.c.
1020 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1022 * Added new configuration options and blocks:
1023 keepalive_secs, reconnect_count, reconnect_interval,
1024 reconnect_interval_max, reconnect_keep_trying and
1025 require_reverser_lookup. Added ConnectionParam block, and
1026 implemented the connection parameters when connecting as
1027 initiator and when accepting connections as responder.
1029 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1030 whether given configuration value has been given already.
1032 Affected files silcd/serverconfig.[c], server.[c].
1034 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1035 algorithm parts and created new file silcalgs.conf, that
1036 is now included from the example_silcd.conf.in.
1038 * Optimized the silc_server_connect_to_router_second to take
1039 the connection configuration object from the SilcServerConnection
1040 object instead of finding it during the connecting phase.
1041 Added the configuration object to SilcServerConnection struct.
1042 Affected files silcd/server_internal.h, server.c.
1044 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1046 * Add the client on channel after it was resolved at the
1047 channel message receiving, and it was not already on the
1048 channel. Affected file lib/silcclient/client_channel.c.
1050 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1058 * Unified the serverconfig.[ch]'s helper function interface.
1059 Affected file silcd/serverconfig.[ch].
1061 * Removed doc/example_silc.conf.in since it is redundant.
1062 The make install will now install irssi/silc.conf file.
1064 * Added new Passphrase and Publickey authentication methods to
1065 config file, allowing both public key and passphrase based
1066 authentication to be set at the same time.
1068 Added `prefer_passphrase_auth' setting in config file which
1069 can be used to set to prefer passwd auth if both passwd and
1070 public key is set. If not set, public key is preferred.
1071 This has effect only when being initiator (responder will try
1074 Added support for authentication with passphrase and public key
1075 at the same time. The passphrase is tried first always since
1076 it is faster to check.
1078 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1080 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1082 * Merged the new SILC Config library, with the server parsing
1083 support. Read the header file silcconfig.h or the toolkit
1084 documentation for the news. Affected files are
1085 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]

1093 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1095 * The silc_cipher_register, silc_hash_register and
1096 silc_hmac_register now checks if the object to be registered
1097 is registered already. Affected files are
1098 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
1100 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1106 * Allow zero length channel messages inside the Channel Message
1107 Payload. Affected file lib/silccore/silcchannel.c.
1109 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1110 as header filenames.
1112 * Removed lib/silcclient/README and created HTML file
1113 lib/silcclient/silcclient_using.html, which is now included
1114 as part of Toolkit documentation.
1116 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1118 * Fixed CUMODE_CHANGE notify handling to change the mode of
1119 correct client. Affected file lib/silcclient/client_notify.c.
1121 * Make silc_rng_alloc fail if it cannot allocate the sha1
1122 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1124 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1126 * Fixed the file transfer's key agreement payload to include
1127 zero port also if the hostname is NULL because it could not
1130 Call file transfer monitor callback now also if error occurs
1131 during key agreement protocol.
1133 Changed the silc_client_file_send interface to return the
1134 SilcClientFileError instead of session id. The session ID
1135 is returned into pointer provided as argument.
1137 Check that the file exists locally before sending the
1138 file transfer request at all.
1140 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1142 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1143 error than can occur while key agreement protocol. Affected
1144 file lib/silcclient/silcapi.h.
1146 * Fixed the event_mode CMODE handler to not crash when mode
1147 is changed and +k mode is set in the channel. Affected file
1148 irssi/src/silc/core/silc-channels.c.
1150 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1151 SILC_LOG_WARNING to give out Warning and not Error. Affected
1152 file lib/silcutil/silclog.c.
1154 * Fixed the channel message payload decryption in the function
1155 silc_channel_message_payload_decrypt to not modify the original
1156 buffer before it is verified that the message decrypted
1157 correctly. Otherwise, next time it is called with correct
1158 channel key it won't encrypt since the payload is corrupted.
1159 Affected file lib/silccore/silcchannel.c.
1161 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1163 * Do not constantly resize the window. A fix patch by cras.
1164 Affected file irssi/src/fe-text/screen.c.

1168 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1169 Affected file lib/silcutil/silcnet.c.
1171 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1173 * Fixed a bug in hash table internal routine for traversing
1174 the table with foreach callback. The current entry may
1175 become invalid in the callback but it was referenced after
1176 the callback returned.
1178 Do not allow auto rehashing of hash table during the
1179 silc_hash_table_foreach operation, for same reasons as it is
1180 not allowed for SilcHashTableList. Affected files are
1181 lib/silcutil/silchashtable.[ch].
1183 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1185 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1186 Win32 DLL. extern's in header files are now declared with
1189 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1191 * Fixed private message handling. It used some old code that
1192 caused the client to crash. Affecte file is
1193 lib/silcclient/client_prvmsg.c.
1195 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1197 * Added function silc_client_add_channel,
1198 silc_client_replace_channel_id, and removed functions
1199 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1200 from client library.
1202 * Added cross reference of the joined channels to the
1203 SilcClientEntry, and changed the SilcChannelEntry's
1204 users list to SilcHashTable. The affected files are
1205 lib/silcclient/idlist.[ch].
1207 * Fixed a bug in hash table tarversing. While the hash table
1208 is traversed with SilcHashTableList the table must not be
1209 rehashed. It is now guaranteed that auto rehashable tables
1210 are not rehashed while tarversing the list. Also defined that
1211 silc_hash_table_rehash must not be called while tarversing
1212 the table. Added function silc_hash_table_list_reset that must
1213 be called after the tarversing is over. The affected files are
1214 lib/silcutil/silchashtable.[ch].
1216 * Changed all hash table traversing to call the new
1217 silc_hash_table_list_reset in server and in client library.
1219 * Added function silc_client_on_channel to return the
1220 SilcChannelUser entry if the specified client entry is joined
1221 on the specified channel. This is exported to application as
1222 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1224 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1226 * Fixed founder regaining problem with JOIN command on normal
1227 server. The notify for mode change must be sent always and
1228 not only if !cmd->pending. Affected file silcd/command.c.
1230 * Fixed the WHOWAS command's reply sending to support the
1231 lists correctly. Affected file silcd/command.c.
1233 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1235 * When sending JOIN command to router for processing the
1236 sender's old command identifier was not saved back to the
1237 sender's command context, fixed now. The affected file is
1240 * Create the key in JOIN command of the router did not return
1241 the channel key, added check for this. Affected file is
1244 * Fixed a channel ID update bug in JOIN command reply. Do
1245 not directly upgrade the ID but call the function
1246 silc_idlist_replace_channel_id if the ID was changed.
1247 Affected file silcd/command_reply.c.
1249 * Fixed memory leaks from command calling if it would fail.
1250 Affected file silcd/command.c.
1252 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1254 * Applied patches from cras:
1256 Memory leak fixes around libaries, irssi window resize fix,
1257 new silclist.h and silcdlist.h, all extern inline changed to
1260 * Removed dotconf from lib/dotconf, not needed anymore.
1262 * Removed TRQ from lib/trq, not needed anymore.
1264 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1265 with server connections. Later this will be configurable
1266 in config file after new config file is done. Affected file
1269 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1271 * Fixed a crash in server related to channel announcements.
1272 Affected file silcd/server.c.
1274 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1276 * Fixed memory leaks in silc_server_create_new_channel*
1277 functions. Affected file silcd/server.c.
1279 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1280 which ID was changed. This way the router will send the
1281 user list for the channel again, and server won't be in
1282 desync in some rare circumstances. Affected file is
1283 silcd/packet_receive.c.
1285 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1287 * Check for NULL socket pointer in the function
1288 silc_server_packet_send_to_channel_real. Affected file
1289 silcd/packet_send.c.

1292 list. Affected file silcd/packet_receive.c.
1294 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1296 * Fixed some header addition to Toolkit distribution in
1297 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1299 * Added lib/silcclient/client_ops_example.h as an template
1300 file for application programmers to quickly start using
1301 the SilcClientOperation functions in their application.
1302 Updated the lib/silcclient/README as well to tell about this
1303 nice file made available.
1305 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1307 * Call silc_server_remove_from_channels when removing client
1308 entry when NO_SUCH_CLIENT_ID was received. Affected file
1309 is silcd/command_reply.c.
1311 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1313 * Added server & router operator statistics updating. Affected
1314 file silcd/packet_receive.c and silcd/command.c.
1316 * Fixed the SERVER_SIGNOFF notify handling on normal server
1317 not to save the history information for clients. Same was
1318 fixed earlier in remove_clients_by_server function, but not
1319 here. Affected file silcd/packet_receive.c.
1321 * Raised the default connection-retry count from 4 to 7 in
1322 server. Affected file silcd/server.h.
1324 * Cancel any possible reconnect timeouts when we start the
1325 key exchange. Affected file silcd/server.c.
1327 * Do not reconnect on connection failure when SCONNECT was
1328 given. Affected files silcd/server.[ch].
1330 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1332 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1334 * Fixed the NICK command to always give the unformatted
1335 nickname to the one giving the NICK command. If unformatted
1336 nickname is cached already it will be formatted and the
1337 local entry will always get the unformatted nickname.
1338 Affected file lib/silcclient/idlist.c.
1340 * Fixed some double frees from client library commands.
1341 Affected file is lib/silcclient/command.c.
1343 * Fixed CUMODE command in server to assure that no one can
1344 change founder's mode than the founder itself, there was a
1345 little bug. Affected file silcd/command.c.
1347 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1349 * Removed the SilcClientCommandDestructor from the client
1350 libary, it is not needed anymore. Affected files are
1351 lib/silcclient/silcapi.h, command[_reply].[ch],
1352 client_notify, idlist.c.
1354 * Fixed GETKEY command to first resolve client, and then
1355 resolve the server only if the client was not found, instead
1356 of resolving both at the same time. Affected file is
1357 lib/silcclient/command.c.
1359 * Added silc_client_start_key_exchange_cb and lookup the
1360 remote hostname and IP address before starting the key
1361 exchange with server. The affected file is
1362 lib/silcclient/client.c.
1364 * The server's public key is now saved using the IP address
1365 of the server and not the servername for the filename.
1366 The hostname public key filename is checked as an fall back
1367 method if the IP address based filename is not found.
1369 Fixed the GETKEY command to save the fetched server key
1370 in correct filename.
1372 Print the remote server's hostname now when new key is
1373 received during connection process. Affected file is
1374 irssi/src/silc/core/client_ops.c.
1376 * Return always our own public key to the client if it asks
1377 for it with GETKEY command. Affected file silcd/command.c.
1379 * Removed the use_auto_addr variable from default config
1380 file since it was in wrong section. Affected file is
1383 * Fixed TOPIC_CHANGE notification to not route it when it
1384 was sent using silc_server_send_notify_to_channel function.
1385 Affected file silcd/command.c.
1387 * Fixed silc_server_send_notify_kicked to send the kicker's
1388 Client ID also, it was missing. Affected files are
1389 silcd/command.c, silcd/packet_send.[ch].
1391 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1393 * Do not save client history information in SERVER_SIGNOFF.
1394 Fixes the bug in normal server that it does not detect
1395 the client becoming valid after the server becomes back
1396 online. Affected file silcd/server_util.c.
1398 * Added `sock_error' field into the SilcSocketConnection
1399 context. When error occurs during socket operation (read
1400 or write) the error is saved. Added also new function
1401 silc_socket_get_error to return human readable socket error
1402 message. Affected files are lib/silcutil/silcsockconn.[ch],
1403 lib/silcutil/unix/silcunixsockconn.c, and
1404 lib/silcutil/win32/silcwin32sockconn.c.
1406 * The server now prints the socket error message in the
1407 signoff for client. Affected file silcd/server.c.
1409 * Fixed the `created' channel information sending from router
1410 to server in JOIN command. Checks now whether the channel
1411 really was created or not and set it according that.
1413 Fixed the JOIN command to use the client entry's current
1414 ID during the joining procedure instead of the one it sent
1415 in the command (it is checked though), since it can change
1416 between the packet processing and command processing, and
1417 would just case unnecessary pain in the client end. Affected
1418 file silcd/command.c.
1420 * Fixed a channel key payload sending to use correct channel
1421 ID when the server was forced to change the channel's ID by
1422 router. Router sent the key payload with the old Channel ID.
1423 Affected file silcd/packet_receive.c.
1425 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1427 * Call silc_server_save_channel_key only if the key payload
1428 was provided in the JOIN command's command reply. Affected
1429 file silcd/command_reply.c.
1431 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1433 * Fixed silc_mp_sizeinbase to return the value correctly with
1434 MPI. Affected file lib/silcmath/mp_mpi.c.
1436 * Fixed the stop_server signal to correctly stop the scheduler
1437 and gracefully stop the server when SIGTERM or SIGINT signals
1438 are received. Affected file silcd/silcd.c.
1440 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1442 * Simple handling of TERM and HUP signals. Also added some log
1443 flushing call around. Affected file is
1446 * Fixed small bugs in silclog.c. Now buffering output will take
1447 effect after 10 seconds since startup: This will ensure that
1448 no important startup messages are lost. Also output redirection
1449 will preserve original format ([Date] [Type] message).
1450 Affected file is lib/silcutil/silclog.c.
1452 * Added two options to the config file, in the logging section:
1453 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1454 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1456 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1458 * Do not print the warning about log files not being initialized
1459 more than once to avoid excess logging. Affected file is
1460 lib/silcutil/silclog.c.
1462 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1463 the SIM copying in make install in Makefile.am.pre.
1465 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1467 * Rewritten silclog APIs. Globally interesting changes follows:
1468 silc_log_set_files() changed to silc_log_set_file().
1469 silc_log_set_callbacks() changed to silc_log_set_callback().
1470 ROBOdoc documented silclog header file.
1471 SilcLogCb now returns bool to wether inihibit the default
1472 handler or not (to keep the old behaviour return always TRUE).
1473 The new APIs should also fix the problem of the
1474 silcd_error.log file that was written in the current directory.
1477 Log files streams will remain opened after silc_log_set_file()
1478 call, means less CPU usage notably on high traffic servers.
1479 File streams are now full buffered, and flushed to the disk
1480 every 5 minutes, lesses HD activity and CPU usage.
1481 Messages can be redirected, allowing admins to configure
1482 one single logfile for all server messages.
1483 the silc_log_quick global variable to activate fast-logging.
1484 Affected files lib/silcutil/silclog.[ch]
1486 * Changed some code to conform new silclog APIs. Affected
1487 files are doc/example_silcd.conf.in, silcd/server.c
1488 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1491 * Fixed a memory leak that could occur in some situations.
1492 Affected file silcd/serverconfig.c.
1494 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1496 * Added the silc_client_del_client to remove the client from
1497 all channels as well. Affected file lib/silcclient/idlist.c.
1499 * Fixed the client library to correctly remove the client
1500 from all channels when the client entry is being destroyed.
1501 Affected file lib/silcclient/client_notify.c, command.c.
1503 * Added auto-nicking support to the client library. If the
1504 applicatio now sets client->nickname it will be sent to the
1505 server after connecting by the library. This way for example
1506 SILCNICK (or IRCNICK) environment variables will have effect
1507 and always change the nickname automatically to whatever
1508 it is wanted. Affected file lib/silcclient/client.[ch].
1510 * Renamed silc_server_command_bad_chars to the
1511 silc_server_name_bad_chars and moved it to the
1512 silcd/server_util.[ch]. Added also new function
1513 silc_server_name_modify_bad to return nickname that
1514 includes bad characters as new nickname without those
1515 bad characters. This check and modify is now used in
1516 silc_server_new_client when the username is initially set
1517 as nickname, so it must be checked to be valid nickname.
1518 Affected file silcd/packet_receive.c.
1520 * The nickname length is now taken from the packet for real
1521 and not trusted to strlen() since it clearly can return
1522 wrong length for nickname including bad characters. This
1523 also applies to channel names. Affected file silcd/command.c.
1525 * Removed the lib/silcsilm/modules directory. Modules are now
1526 compiled into the lib/silcsim. Fixed the copying of the
1527 modules to follow symbolic links in Makefile.am.pre.
1529 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1531 * Fixed silc_string_regexify list creation. Fixes bugs with
1532 BAN and INVITE commands in server. The affected file is
1533 lib/silcutil/unix/silcunixutil.c.
1535 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * Removed the command destructor entirely from the server's
1538 command and command reply routines. It is not needed, and
1539 its usage was buggy and caused crashes. Affected files are
1540 silcd/command[_reply].[ch].
1542 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Cancel protocol and NULL sock->protocol if timeout
1545 occurred during protocol. Affected file silcd/server.c.
1547 * Cancel protocol timeouts always before calling the final
1548 callback, to assure that after final callback is called
1549 no other state will be called for the protocol anymore.
1550 Affected file silcd/protocol.c.
1552 * Print error log if incoming connection configuration could
1553 not be found. Affected file silcd/server.c.
1555 * Fixed JOIN command to correctly save the founder mode
1556 to the client on normal SILC server, when the channel
1557 was created by the router. Affected file silcd/command.c.
1559 * Fixed LIST command (hopefully) to send correct reply
1560 packets. Affected file silcd/command.c.
1562 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1564 * The silc_packet_receive_process now returns FALSE if the
1565 read data was invalid packet, and TRUE if it was ok.
1567 The server now checks that if unauthenticated connection
1568 sends data and its processing fails the server will close
1569 the connection since it could be a malicious flooder.
1571 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1573 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1575 * Make sure the warning about error opening a log file is
1576 printed only once and not everytime it fails (produces
1577 too much useless log). Affected file lib/silcutil/silclog.c.
1579 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1581 * Made the silc_server_daemonise() function more readable.
1582 Affected file silcd/server.c.
1584 * Pid file is now optional, the user may comment it out from
1585 the config file. Removed define SILC_SERVER_PID_FILE, we
1586 don't need a default any longer. Affected file
1587 configure.in.pre, lib/Makefile.am.pre.
1589 * Make some use of the pid file. The server now dies at startup
1590 if it detects a valid pid file on his path. The server would
1591 die anyway in this circumstance, because of the bind() failure.
1592 Affected file silcd/silcd.c.
1594 * No longer compiling lib/dotconf.
1596 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Fixed JOIN command parsing not to crash. Affected file
1599 lib/silcclient/command.c.
1601 * Fied the NICK_CHANGE notify to add the new client entry
1602 even it is resolved. This removes an <[unknown]> nick
1603 thingy bug in the client. Affected file is
1604 lib/silcclient/client_notify.c.
1606 * Do not try to allocate 0 bytes (efence does not like it)
1607 in lib/silccore/silccomand.c when encoding payload.
1609 * Do not take IRCNICK as nickname in Irssi SILC client since
1610 it is not possible to set nickname before hand connecting
1611 the server (TODO has an entry about adding auto-nicking
1614 * Changed the silc_server_command_pending to check whether
1615 there already exists an pending entry with the specified
1616 command, command identifier and pending callback. This is
1617 to fix IDENTIFY and WHOIS related crashes that may register
1618 multiple pending commands with same identifier. Affected
1619 file silcd/command.c.
1621 * Fixed the server to reconnect to the router even if it
1622 was already reconnecting and EOF was received. This to
1623 fix a possibility that the server wouldn't ever try to
1624 auto-reconnect to the router. Affected file silcd/server.c.
1626 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1628 * Fixed the server's password authentication to use the
1629 length of the locally saved password, and not the one
1630 sent in the packet. Affected file silcd/protocol.c.
1632 * Fixed same password authentication problem in the
1633 Authentication Payload handling routines in
1634 lib/silccore/silcauth.c.
1636 * Yet another password authentication problem fixed with
1637 channel password handling in silcd/command.c.
1639 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * If first character of string in silc_parse_userfqdn is '@'
1642 then do not parse it. Affected file is
1643 lib/silcutil/silcutil.c.
1645 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Fixed minor bug in IDENTIFY command reply sending, which
1648 caused various weird problems during JOIN when it was
1649 resolving names for users. Affected file silcd/command.c.
1651 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Fixed the IDENTIFY command reply sending to chech better valid
1654 clients. It was possible to send incomplete list of replies.
1655 Affected file silcd/command.c.
1657 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Added silc_client_command[s]_[un]register functions now to
1660 dynamically register the commands in client library. Removed
1661 the static table of commands. This allows the client library
1662 to call commands without causing the application to know about
1663 what commands library has called.
1665 Removed the INFO command reply kludge to detect when the command
1666 was called by library. Now library use its own command reply
1667 function for INFO command.
1669 Added function silc_client_command_call to call a command.
1670 Application can use it to call command, not access the structure
1673 Now all commands that are sent by the client library (not
1674 explicitly sent by application) use own command reply functions.
1676 Affected files around lib/silcclient/ and in
1677 irssi/src/silc/core/.
1679 * Fixed the WHOIS command reply sending to chech better valid
1680 clients. It was possible to send incomplete list of replies.
1682 Fixed the WHOIS and IDENTIFY to send the request to router
1683 if normal server did not do it and did not find any results.
1685 Affected file silcd/command.c.
1687 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Moved the internal data from SilcClient context into its
1690 own file, not accesible to application. Affected files
1691 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1692 and other files in client library.
1694 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Added doc/examples installation target in Makefile.am.pre.
1699 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1702 commands the found client entry will be removed from the
1703 cache, after notifying application about the error. Affected
1704 file lib/silcclient/command_reply.c.
1706 * Changed the /MSG to check for exact nickname user gave, and
1707 not let `nick' match `nick@host' if it is only one found. Now,
1708 user must type the exact nickname (like nick@host2) even if
1709 there are no more than one same nicks found. This is to avoid
1710 a possibility of sending nickname to wrong nickname since
1711 `nick' could match `nick@host'. Affected file is
1712 irssi/src/core/silc-servers.c.
1714 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1716 * Do not print "you are now server operator" or similar when
1717 giving /away command. Affected files are
1718 irssi/src/silc/core/client_ops.c, silc-servers.h.
1720 * Made the silc_server_command_pending_error_check to send
1721 the same command reply payload it received back to the
1722 original sender of the command. This way all arguments
1723 that was received by the server will be received by the
1724 client too. Affected file silcd/command.c.
1726 * Added the silc_idcache_add to return the created cache entry
1727 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1729 * Add global clients to expire if they are not on any channel.
1730 This is because normal server will never know if they signoff
1731 if they are not on any channel. The cache expiry will take
1732 case of these entries. This is done by normal servers only.
1733 The affected files are silcd/command_reply.c,
1734 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1736 * If server receives invalid ID notification for WHOIS or
1737 IDENTIFY and the ID exists in the lists, it is removed.
1738 Affected file silcd/command_reply.c.
1740 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1741 in client then client entry that it matches is searched and
1742 the nickname is printed on the screen for user. Affected
1743 file irssi/src/silc/core/client_ops.c.
1745 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1747 * Use cache entry expire time in the LIST command reply to
1748 purge old entries from the cache after the LIST command
1749 reply has been received. This way we don't have non-existent
1750 entries in the cache for too long. Affected file is
1751 silcd/command_reply.c.
1753 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * If we are normal server, and we've not resolved client info
1756 in WHOIS or IDENTIFY from router, and it is global client,
1757 we'll check whether it is on some channel. If it is not
1758 then we cannot be sure about its validity and will resolve it
1759 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1760 file silcd/command.c.
1762 * Search channel by name (if possible) rather than by ID
1763 in IDENTIFY command's command reply. Affected file is
1764 silcd/command_reply.c.
1766 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1769 Updated specs and implemented it. Affected file silcd/command.c,
1770 silcd/packet_send.c and silcd/packet_receive.c.
1772 * Implemented the <founder auth> payload handling in the JOIN
1773 command. If provided all conditions for channel joining
1774 except requirement to provide correct passphrase can be
1775 overrided by the channel founder. Updated the protocol specs.
1776 Affected file silcd/command.c.
1778 Added support for founder auth in JOIN command in client
1779 library. Fixed the parsing of the JOIN command now to support
1780 all options as they should be. The affected file is
1781 lib/silcclient/command.c.
1783 * Optimized the WHOIS and IDENTIFY commands to send the request
1784 to router only if it includes nicknames or other names. If
1785 they include only IDs then check the local cache first before
1786 routing. Affected file is silcd/command.c.
1788 * Added channels topic announcements. Affected file is
1789 silcd/packet_receive.c and silcd/server.c.
1791 * Fixed the silc_server_send_notify_topic_set to really destine
1792 the packet to channel. Affected file silcd/packet_send.c.
1794 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1795 library. Affected file lib/silcclient/client_notify.c.
1797 * Added UMODE announcements. Affected file silcd/server.c.
1799 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1801 * Memory leak fixes in:
1803 lib/silcutil/silcsockconn.c
1804 lib/silcske/silcske.c
1805 lib/silcske/groups.c
1807 lib/silccrypt/silcpkcs.c
1808 lib/silccore/silccommand.c
1809 lib/silccore/silcidcache.c
1814 * ROBOdoc documented the lib/silcske/groups.h file and a
1815 bit changed the interface for better.
1817 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1819 * Update the client entry context in the ID cache after
1820 nick change. Affected file lib/silcclient/command.c.
1821 Fixes the CUMODE command when regaining founder privileges,
1822 and a little WHOIS problem.
1824 * Fixed silc_net_gethostbyname to correctly call the
1825 inet_ntop. Affected file lib/silcutil/silcnet.c.
1827 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1829 * Added IPv6 support checking to the configure.in.pre, added
1830 also --enable-ipv6 option to override the check. Affected
1831 file configure.in.pre.
1833 * The silc_thread_create now calls the start function
1834 directly if threads support is not compiled in. Removes
1835 ugly #ifdef's from generic code. Affected files are
1836 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1838 * Added silc_net_gethostby[name/addr]_async to asynchronously
1839 resolve. Affected files are lib/silcutil/silcnet.[ch].
1841 * Added support for rendering IPv6 based server, client and
1842 channel IDs. Affected file lib/silcutil/silcutil.c.
1844 * Added support for creating IPv6 based server IDs. Affected
1845 file is silcd/serverid.c.
1847 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1849 * Added silc_net_gethostby[addr/name] into the
1850 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1851 routines. Added silc_net_is_ip[4/6]. Affected file is
1852 lib/silcutil/unix/silcunixnet.c. All routines that take
1853 address as argument now supports both IPv4 and IPv6 addresses.
1855 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1857 * Fixed LIST command reply sending in server. Affected file
1860 * Server now sends the kicker's client ID in the KICK notify
1861 to the kicked client. Affected file silcd/command.c.
1863 * The client library now parses the kickers client ID and
1864 UI displays it. Affected files lib/silcclient/client_notify.c
1865 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1867 * Made all payload parsing function prototypes consistent.
1868 They all take now const unsigned char * and uint32 pair as
1869 the payload data instead of SilcBuffer. Changes all around
1870 the source tree. Other unsigned char* -> const unsigned char*
1871 changes around the tree as well.
1873 * Optimized SFTP client and server packet sending not to
1874 allocate new buffer for each packet but to recycle the
1875 first allocated buffer. Affected files are
1876 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1878 * Optimized the SFTP client to use SilcList instead of
1879 SilcDList for requests, because it is faster. Affected file
1880 is lib/silcsftp/sftp_client.c.
1882 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1883 into lib/silccore/silcid.[ch].
1885 Renamed silcpayload.[ch] into silcargument.[ch].
1887 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1889 * If client entry is deleted with active key agreement
1890 session, abort the session.
1892 The silc_client_abort_key_agreement now calls the completion
1893 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1895 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1898 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Don't use __restrict in older GCC's. Affected file is
1901 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1903 * silc_net_localhost now attempts to reverse lookup the
1904 IP/hostname. Affected file lib/silcutil/silcnet.c.
1906 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1907 command. It can be used to gain founder privileges at
1908 the same time when joining the channel.
1910 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1911 kicker's client ID as well. Updated protocol specs.
1913 Defined that the server must send SILC_COMMAND_IDENTIFY
1914 command reply with error status to client who sent
1915 private message with invalid client ID.
1917 Updated the protocol specification.
1919 * Added silc_server_send_command_reply to send any
1920 command reply. Affected file silcd/packet_send.[ch].
1922 * Added silc_id_payload_encode_data to encode ID payload
1923 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1925 * The server now send IDENTIFY command reply with error
1926 status if client ID in private message is invalid. Affected
1927 file silcd/packet_receive.c.
1929 * Save the server key file with server's IP address in
1930 the filename instead of hostname. The affected file is
1931 irssi/src/silc/core/client_ops.c.
1933 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1938 * Added libtool support for compiling shared objects in
1939 lib/silcsim. Affected file configure.in.pre and
1940 lib/silcsim/Makefile.am. Original patch by cras.
1942 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1944 * Pid file configuration, and server's config file fixes
1945 patch by toma. Updated CREDITS file.
1947 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1949 * Fixed silc_client_channel_message to not try to decrypt
1950 the message twice if it resolved the destination client
1951 information. This could cause of dropping one channel
1952 message. Affected file lib/silcclient/client_channel.c.
1954 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1957 lib/silcclient/client.c. This function is used when the SILC
1958 Client is run under some other scheduler, or event loop or
1959 main loop. On GUI applications, for example this may be
1960 desired to used to run the client under the GUI application's
1961 main loop. Typically the GUI application would register an
1962 idle task that calls this function multiple times in a second
1963 to quickly process the SILC specific data.
1965 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1967 * Fixed silc_server_drop() for dropping the supplementary
1968 groups as well, this could cause a security hole on some
1971 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

1984 Affected file irssi/src/silc/core/client_ops.c.
1986 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Fixed the silc_idcache_list_* routines to really support
1989 the dynamic list. Fixes a crash. Affected file is
1990 lib/silccore/silcidcache.c.
1992 * Fixed the LIST command reply to really call LIST command's
1993 pending callbacks. Affected file silcd/command_reply.c.
1995 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Update conn->local_entry->nickname after giving NICK
1998 command. Affected file lib/silcclient/command.c.

2002 * Added the [pid] option to the silcd configuration file
2004 Affected files: serverconfig.[ch] and silcd.c
2006 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2008 * Save fingerprint in WHOIS command reply in server.
2009 Affected file silcd/command_reply.c.
2011 * Fixed NICK commands pending callback registration.
2012 Affected file lib/silcclient/command.c.
2014 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Use ++server->cmd_ident when sending commands in server,
2017 instead of random number. Affected file silcd/command.c.
2019 * Fixed GETKEY command reply to call actually GETKEY pending
2020 command callbacks. Affected file silcd/command_reply.c.
2022 * A bit stricter check for nicknames. Check for same nickname
2023 in NICK command also. Affected file silcd/command.c.
2025 * Do not call INFO command everytime client ID changes, only
2026 during first connecting. Affected file lib/silcclient/client.c.
2028 * Set the new nickname only after successful command reply for
2029 NICK command is returned by server. Affected file
2030 lib/silcclient/command.c.
2032 * Remove nicknames from nicklist during server_signoff notify.
2033 Should fix /NAMES bit more. The affected file is
2034 irssi/src/silc/core/silc-channels.c.
2036 * Added `fingerprint' field to the SilcIDListData in the
2037 silcd/idlist.h to hold the fingerprint of the client's
2040 Send the fingerprint of the client's public key in WHOIS
2043 Affected files silcd/command.c, and silcd/idlist.[ch].
2045 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2046 create fingerprint from given data.
2048 * Show the fingerprint of the client's public key in WHOIS.
2049 Affected files irssi/src/module-formats.[ch] and
2050 irssi/src/silc/core/client_ops.c.
2052 * Format the multiple same nicknames also during JOIN and
2053 NICK_CHANGE notifys. Affected file is
2054 lib/silcclient/client_notify.c.
2056 * Do not print error on screen for invalid private message
2057 payload since it can come if someone is sending private
2058 messages with wrong key. Affected file
2059 lib/silccore/silcprivate.c.
2061 * Fixed multiple concurrent /PING crash. Affected file
2062 lib/silcclient/command.c.
2064 * Changed the wrong ID encoding. All IP addresses must be
2065 in MSB first order in encoded format. They were encoded
2066 wrong and was in LSB format. Affected files are
2067 silcd/serverid.c, lib/silcutil/silcutil.c.
2069 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2071 * Call the `connect' client operation through the scheduler
2072 in case of error. Affected file lib/silcclient/client.c.
2074 * Call the `failure' client operation even if the error
2075 occurred locally during a protocol. Affected file is
2076 lib/silcclient/protocol.c.
2078 * Added support of sending LIST command to router from normal
2079 server. This way normal server can get list of all channels
2080 in the network too. Fixed the channel list sending in the
2081 server too. Affected files are silcd/command.c, and
2082 silcd/command_reply.[ch].
2084 * Added silc_server_update_channels_by_server and
2085 silc_server_remove_channels_by_server. They are used during
2086 disconnection of primary router and in backup router protocol.
2087 Affected file silcd/server_util.[ch], silcd/server.c and
2088 silcd/server_backup.c.
2090 * Fixed channel adding to global list in IDENTIFY command
2091 reply in server. Affected file silcd/command_reply.c.
2093 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * If the incoming packet type is REKEY or REKEY_DONE process
2096 that packet always synchronously. Fixes yet another MAC
2097 failed error on slow (dialup) connections. Affected file
2098 lib/silcclient/client.c and silcd/server.c.
2100 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Call check_version SKE callback for initiator too. Affected
2103 file lib/silcske/silcske.c.
2105 * Implemented fix for security hole found in the SKE that was
2106 fixed in the specification few days back; the initiator's
2107 public key is now added to the HASH value computation.
2108 Added backwards support for the old way of doing it too, for
2109 old clients and old servers. Affected file is
2110 lib/silcske/silcske.c.
2112 * Enabled mutual authentication by default in SKE. If initiator
2113 is not providing mutual authentication the responder will
2114 force it. This will provide the proof of posession of the
2115 private key for responder. The affected files are
2116 lib/silcclient/protocol.c and silcd/protocol.c.
2118 * Do not cache anymore the server's public key during SKE.
2119 We do mutual authentication so the proof of posession of
2120 private key is done, and if the server is authenticated in
2121 conn auth protocol with public key we must have the public
2122 key already. Affected file silcd/protocol.c.
2124 * Added new global debug variable: silc_debug_hexdump. If
2125 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2126 file lib/silcutil/silclog.[ch].
2128 * Fixed compilation warning due to char * -> const char *.
2129 Affected files lib/silcutil/silcnet.h, and
2130 lib/silccore/silcauth.[ch].
2132 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Fixed CMODE command when new channel key was created. If
2135 the creation failed the old key was removed. Next time giving
2136 same command would crash the server since the old key was
2137 freed already. Affected file silcd/command.c.
2139 * Fixed the silc_server_announce_get_channels to not crash
2140 on reconnect. Affected file silcd/server.c.
2142 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2144 * Added silc_log_set_debug_string function to set a regex
2145 string to match for debug output. Only the function names,
2146 or filenames matching the given debug string is actually
2147 printed. This way it is possible to filter out those debug
2148 strings that user is not interested in.
2150 Fixed a bug in silc_string_regexify.
2152 Affected files lib/silcutil/silclog.[ch], and
2153 lib/silcutil/unix/silcunixutil.c.
2155 * Changed the -d options in both server and Irssi SILC client
2156 to take the debug string as argument. Affected files
2157 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2159 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Added silc_hash_babbleprint to create a Bubble Babble
2162 Encoded fingerprint. The encoding is developed by Antti
2163 Huima (draft-huima-babble-01.txt), and it creates human
2164 readable strings out of binary data. Affected file
2165 lib/silccrypt/silchash.[ch].
2167 * Print the babble print now in addition of fingerprint as well
2168 in Irssi SILC client. Affected files are
2169 irssi/src/fe-common/silc/module-formats.[ch],
2170 irssi/src/fe-common/silc/core/client_ops.c.
2172 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * Fixed a security problem found in SKE. The initiator's
2175 public key too is now added to the HASH hash value creation
2176 which is signed by the responder to create the SIGN value.
2177 This will prevent anyone in the middle to lie to the responder
2178 about the initiator's public key. If this is done now, the
2179 man in the middle will get caught. Updated the protocol
2182 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Better installation directory handling. Configure module
2185 paths and other paths automatically to example_silc* files
2186 in doc/. A patch by toma.
2188 * Fixed compiler warning from MPI library, and from SILC RNG.
2191 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2192 It can be configured with ./configure. A patch by toma.
2194 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2196 * Find correct make to use in prepare-clean. A patch by
2197 toma. Affected file prepare-clean.
2199 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2201 * Added irssi variables use_auto_addr, auto_bind_ip,
2202 auto_bind_port and auto_public_ip.
2204 * Changed the interface for silc_client_send_key_agreement
2205 in lib/silcclient/silcapi.h
2209 irssi/src/silc/core/silc-core.c
2211 lib/silcclient/silcapi.h
2212 irssi/src/silc/core/silc-channels.c
2213 lib/silcclient/client_keyagr.c
2216 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2218 * Added silc_pkcs_public_key_compare to compare two
2219 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2221 * Check that the client who set the founder mode on the
2222 channel is the same client that is giving the founder
2223 mode to itself. It is done by comparing the saved public
2224 key (it is saved even in the authentication is passphrase).
2225 Affected file silcd/command.c.
2227 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2229 * Do not process packet for disconnected socket connection.
2230 Affected file lib/silccore/silcpacket.c.
2232 * Process the DISCONNECT packet through scheduler in the
2233 client library. Affected file lib/silcclient/client.c.
2235 * Fixed the silc_client_packet_parse to not to increase
2236 the packet sequence number if the conn->sock and the
2237 current socket connection is not same. This can happen
2238 for example during key agreement when the conn includes
2239 multiple socket connections (listeners). Affected file
2240 lib/silcclient/client.c.
2242 * The sender of the file transfer request now provides also
2243 the pointer (listener) for the key exchange protocol. If
2244 the listener cannot be created then it sends empty key
2245 agreement and lets the receiver provide the listener.
2247 Added `local_ip' and `local_port' arguments to the
2248 silc_client_file_send. If they are provided they are used,
2249 if not then it will attempt to find local IP address, if
2250 not found or bind fails then the remote client will provide
2253 Affected files are lib/silcclient/client_ftp.c and
2254 lib/silcclient/silcapi.h.
2256 * Extended the FILE SEND command to support defining the
2257 local IP and port for key exchange listener. They are
2258 optional. Affected file irssi/src/silc/core/silc-servers.c.
2260 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Defined to WHOIS command reply the sending of fingerprint
2263 of the client's public key (if the proof of posession of the
2264 corresponding private key is verified by the server).
2265 Updated to the protocol specification.
2267 * Added support of receiving the client's public key's
2268 fingerprint in command reply in client library. Affected
2269 file is lib/silcclient/command_reply.c, and
2270 lib/silcclient/idlist.[ch].
2272 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Do not send over 128 chars long nickname to the server
2275 in NICK command. Affected file lib/silcclient/command.c.
2277 * Do not send over 256 chars long channel names to the server
2278 in JOIN command. Affected file lib/silcclient/command.c.
2280 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Assure that silc_server_close_connection cannot be called
2283 twice for same socket context. Affected file is
2286 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Send error message to application if opening file for
2289 writing during file transfer fails. Affected file is
2290 lib/silcclient/client_ftp.c.
2292 Remove all file transfer sessions for a client that we're
2293 removing from ID cache.
2295 Affected file is lib/silcclient/client_ftp.c.
2297 * Fixed silc_net_addr2bin to return correct address. Affected
2298 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2300 * Fixed file transfer session removing on signoff notify.
2301 Affected file irssi/src/silc/core/silc-servers.c.
2303 * Added the SilcClientFileError to be returned in the monitor
2304 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2305 Affected file lib/silcclient/silcapi.h.
2307 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2309 * Fixed a crash in silc_client_ftp_free_sessions and
2310 silc_client_ftp_session_free_client. Affected file
2311 lib/silcclient/client_ftp.c.
2313 * Added `disabled' field in the SilcChannelEntry in the server
2314 to indicate if the server entry is disabled. Affected file
2315 silcd/idlist.h, silcd/command[_reply].c.
2317 * SILC server adds now /var/run/silcd.pid everytime it is
2318 started. Affected file silcd/silcd.c.
2320 * Added silc_server_packet_send_clients to send a packet to
2321 the provided table of client entries. Affected file
2322 silcd/packet_send.[ch].
2324 * Fixed a crash in client resolving in client_prvmsg.c in
2325 client library. Affected file lib/silcclient/client_prvmsg.c.
2327 * Do not actually remove the client directly from ID cache
2328 during SERVER_SIGNOFF, but invalidate it. This way we
2329 preserve the WHOWAS info for the client. Affected file
2330 silcd/server_util.c.
2332 * Fixed SERVER_SIGNOFF notify handling in the server. The
2333 server is now able to process incoming SERVER_SIGNOFF notify
2334 for a server that it doesn't even know about. It will remove
2335 the clients provided in the notify. Affected file
2336 silcd/packet_receive.c.
2338 * Check for partial packet in data queue after every packet that
2339 was found from the queue. Return and wait for more data if
2340 there is partial data in queue. Affected file is
2341 lib/silccore/silcpacket.c.
2343 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Added SilcClietFileError enum to indicate error in
2346 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2347 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2348 Affected files lib/silcclient/silcapi.h and
2349 lib/silcclient/client_ftp.c.
2351 * Check that newsize in silc_buffer_realloc is larger than
2352 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2354 * Added better monitor of file transfers. It now monitors
2355 key agreement protocol during the file transfer too. Added
2356 error reporting too. Affected files
2357 irssi/src/silc/core/silc-servers.c,
2358 irssi/src/fe-common/silc/module-formats.[ch].
2360 * Wrote a help file for FILE command.
2362 * Added silc_rng_global_get_byte_fast to get not-so-secure
2363 random data as fast as possible. Random data is read from
2364 /dev/urandom if available and from the SILC RNG if not
2365 available. It is used in padding generation. Affected file
2366 lib/silccrypt/silcrng.[ch].
2368 * All packets in client library are now processed synchronously.
2369 Optimized packet processing a lot. Affected file
2370 lib/silcclient/client.c.
2372 * All server connection packets are processing synchronously
2373 now in server, to optimize packet processing. Affected file
2376 * Include files are installed now only in Toolkit distribution
2377 if make install is given. Affected files: all Makefile.am's.
2379 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2381 * Assure that silc_client_notify_by_server_resolve does not
2382 resolve the client information multiple times. If it cannot
2383 be found by the first it cannot be found at all. Affected
2384 file lib/silcclient/client_notify.c.
2386 * Fixed WHOWAS command reply calling. Affected file
2387 lib/silcclient/command_reply.c.
2389 * Removed all references to silc_idlist_get_client from the
2390 Irssi SILC client since that call is internal call used by
2391 the library. The Irssi SILC client will use now client
2392 retrieval functions found in silcapi.h.
2394 * Fixed a bug in resolving nickname info before sending
2395 private message. It used freed memory. Affected file
2396 irssi/src/silc/core/silc-servers.c.
2398 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * Assure my_channels statistics cannot go negative in server.
2401 Affected files silcd/server.c, silcd/server_util.c.
2403 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2407 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2409 * Win32 Toolkit changes. Affected files
2410 win32/silc.dsw, win32/libsilc/libsilc.def,
2411 win32/libsilcclient/libsilc.def,

2413 lib/sftp/sftp_fs_memory.c.
2415 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Added silc_net_localip to return local host's IP address.
2418 Affected file lib/silcutil/silcnet.[ch].
2420 * If key exchange or rekey protocol is active for a connection
2421 parse all packets syncronously since there might be packets
2422 in packet queue that we are not able to process without first
2423 processing packets before them. Affected file silcd/server,
2424 lib/silcclient/client.c.
2426 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2427 whether library should continue processing the packet.
2428 Affected file lib/silccore/silcpacket.h.
2430 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2431 SilcSFTPMonitorData to SFTP server to monitor various
2432 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2433 lib/silcsftp/sftp_server.c.
2435 * Added silc_file_size to return file size. Affected file
2436 lib/silcutil/silcutil.[ch].
2438 * Implemented the file transfer support for the client library.
2439 Added preliminary support for simple client to client one-file
2440 transmission. Affected file lib/silcclient/client_ftp.c,
2441 lib/silccilent/client.[ch].
2443 * Added new local command FILE to the Irssi SILC Client.
2444 It is used to perform the file transfer. It has subcommands
2445 SEND, RECEIVE, SHOW and CLOSE. Affected files
2446 irssi/src/silc/core/client_ops.c,
2447 irssi/src/silc/core/silc-server.[ch].
2449 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2451 * Relay the SILC_PACKET_FTP in the server. Affected files
2452 silcd/server.c and silcd/packet_receive.c.
2454 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2456 * Renamed silc_file_read and silc_file_write to functions
2457 silc_file_readfile and silc_file_writefile. Added function
2458 silc_file_open and silc_file_close. Affected files
2459 lib/silcutil/silcutil.[ch].
2461 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Resolve the client info when received private message or
2464 channel message for a client which nickname we don't know.
2465 Affected files lib/silcclient/client_prvmsg.c and
2466 lib/silcclient/client_channel.c.
2468 * Do not crash in /KEY if client is not connected. Affected
2469 file irssi/src/silc/core/silc-channels.c.
2471 * Added SilcClientStatus field to the SilcClientEntry in the
2472 lib/silcclient/idlist.h.
2474 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2475 is incomplete and is being resolved, it won't be resolved
2478 Make sure also that USERS command reply does not resolve
2479 twice information. Affected file is
2480 lib/silcclient/command_reply.c.
2482 Make sure that silc_client_get_clients_by_list does not
2483 resolve twice same information.
2485 * Check for valid client->id in the silc_server_free_client_data.
2486 Affected file silcd/server.c.
2488 * Fixed /GETKEY nick@server not to crash if the server entry
2489 is not found. Affected file lib/silcclient/command.c.
2491 * Fixed the silc_server_check_cmode_rights to check the
2492 requested modes correctly. Affected file silcd/command.c.
2494 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Better checks for non-printable chars in nick added.
2497 Affected file silcd/command.c.
2499 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Call the silc_server_udpate_servers_by_server in the
2502 primary router that comes back online in the backup resuming
2503 protocol. Otherwise it routes packets wrong. Affected file
2504 silcd/server_util.[ch], silcd/server_backup.c.
2506 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2508 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2509 lib/silcutil/silcbuffmt.[ch].
2511 * Redefined the SILC packet header to include the padding
2512 length. Affected file lib/silccore/silcpacket.[ch].
2514 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2515 length for maximum padding up to 128 bytes). Affected
2516 file lib/silccore/silcpacket.h.
2518 * Removed all backwards support for old 0.5.x MAC thingies.
2519 The SILC packet header change makes it impossible to be
2520 backwards compatible.
2522 * Send the ENDING packet with timeout in the backup resuming
2523 protocol. This is to assure that all routers has connected
2524 to the primary router. Affected file silcd/server_backup.c.
2526 * Changed the RNG to take the first IV from random data. It
2527 used to take it from zero actually. Changed the RNG also
2528 to use /dev/urandom during session. /dev/random is used
2529 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2531 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Changed the SILC packet header to have the first two bytes
2534 (the packet length) encrypted. Affected files aroung the
2535 code tree, lib/silccore/silcpacket.[ch]. Removed the
2536 SilcPacketCheckDecrypt callback. It is not needed anymore
2537 since the silc_packet_receive_process will determine now
2538 whether the packet is normal or special.
2540 * Implemented the unidirectional MAC keys. Affected files
2541 lib/silcske/silcske.c, silcd/protocol.c and
2542 lib/silcclient/protocol.c.
2544 * Implemented the packet sequence number to the MAC computation.
2545 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2546 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2547 lib/silcclient/protocol.c.
2549 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Allow backup router to announce servers. All servers
2552 announced by backup router are added to the global list
2553 automatically. Update hte server's socket to our primary
2554 router also when backup router announces a server.
2555 Affected file silcd/packet_receive.c.
2557 * Do not update the client->router in the function
2558 silc_server_udpate_clients_by_server if the client is on
2559 global list. We might fail to find any specific server
2560 for locally connected clients and local cell clients. They
2561 should still use the `from' and not `to' as client->router.
2562 This fixes backup router resuming protocol. Affected file
2563 silcd/server_util.c.
2565 * Decrease channel statistics count only if the channel
2566 deletion worked. Affected files are silcd/server.c and
2567 silcd/server_util.c.
2569 * Added silc_server_update_servers_by_server to update origin
2570 of all server entries. Used during backup router protocol.
2571 Affected files silcd/server_util.[ch], silcd/server.c. and
2572 silcd/backup_router.c.
2574 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2575 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2576 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2577 lib/silccrypt/silchmac.c.
2579 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Assure that router cannot reroute the same channel message
2582 to the sender. Affected file silcd/packet_receive.c.
2584 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Made better checks that the channel message is not sent
2587 to the router it came from. Affected file is
2588 silcd/packet_send.c. Fixed memory leak too.
2590 * Announce informations for incoming router connection, but
2591 only after checking if it is replaced by backup router.
2592 Affected file silcd/packet_receive.c.
2594 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2596 * Fixed the backup resuming protocol to work in multiple
2597 router environment. Affected file silcd/server_backup.c.
2599 * Route packet only to one router in the function
2600 silc_server_packet_send_to_channel. Affected file is
2601 silcd/packet_send.c.
2603 * Fixed silc_server_send_notify_dest to set the broadcast
2604 flag. Fixed the silc_server_send_notify_topic to actually
2605 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2606 Affected file silcd/packet_send.c.
2608 * Changed the SFTP Filesystem interface. Changed the
2609 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2610 the filesystem operation function. The SilcSFTPFilesystem
2611 is now a context that is allocated by all filesystem allocation
2612 functions and it already includes the operations structure
2613 and filesystem specific context. It is given as argument
2614 now to the silc_sftp_server_start. This made the interface
2615 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2616 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2618 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2620 * Changed the backup router adding and getting interfaces
2621 in the server. The router that will be replaced by the
2622 specified backup router is now sent as argument. Affected
2623 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2626 * Added silc_net_addr2bin_ne to return the binary form of
2627 the IP address in network byte order. Affected files
2628 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2630 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2632 * Check for existing server ID in silc_server_new_server
2633 and in silc_server_connect_to_router_final and remove the
2634 old entry if it exists. Affected file silcd/packet_receive.c,
2637 * Send the channel message always to only one router, either
2638 in upstream or downstream. Affected file is
2639 silcd/packet_send.c.
2641 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2643 * Wrote the definition of the backup resuming protocol to the
2644 protocol specification.
2646 * Removed one redundant channel key generation from normal
2647 server during joining procedure. Removed one redundant
2648 channel key sending from server to router during joining
2649 procedure. Affected file silcd/command.c.
2651 * Made minor bugfixes to the backup router resuming protocol.
2652 Affected file silcd/server_backup.c, server.c.
2654 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Added --disable-asm configuration option. Affected files
2657 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2660 * Implemented the backup resuming protocol that is used to
2661 resume the primary router position in the cell after the
2662 primary router comes back online. Affected files
2663 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2664 and silcd/server_util.[ch].
2666 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Sleep two (2) seconds after sending QUIT command to server.
2669 Affected file lib/silcclient/command.c.
2671 * Assure that if outgoing data buffer is pending do not force
2672 send any data. Affected file silcd/packet_send.c.
2674 * Assure that if outgoing data buffer is pending do not force
2675 send any data. Affected file lib/silcclient/client.c.
2677 * Implemented the backup router support when the primary router
2678 goes down. The servers and routers can now use the backup
2679 router as new primary router without loosing connectivity.
2681 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2683 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2684 in the server to indicate disabled entry. All data read
2685 from the connection will be ignored and no data is sent
2686 for entry that is disabled. Affected files are
2687 silcd/idlist.h, silcd/server.c.
2689 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Created SFTP client and server test programs in the
2692 lib/silcsftp/tests directory.
2694 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Implemented memory filesystem (virtual filesystem) for
2697 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2700 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Implemented the SFTP (SSH File Transfer Protocol) to the
2703 lib/silcsftp. It includes SFTP client and SFTP server
2706 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2708 * Moved lib/silccore/silcprotocol.[ch] to the
2709 lib/silcutil library.
2711 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2712 take variable argument list pointer as argument. Affected
2713 file lib/silcutil/silcbuffmt.[ch].
2715 * Added silc_buffer_set function that is used to set data
2716 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2717 Affected file lib/silcutil/silcbuffer.h.
2719 * Changed various routines in the core library to use the new
2720 silc_buffer_set instead of allocating new buffer only for
2723 * Added 64-bit value formatting and unformatting support to the
2724 silc_buffer_[un]format routines. Affected file is
2725 lib/silcutil/silcbuffmt.[ch].
2727 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2728 to includes/bitmove.h.
2730 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * Fixed channel user mode saving in client library. Affected
2733 file lib/silcclient/command[_reply].c.
2735 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2737 * Defined the file transfer to the SILC Protocol. Added
2738 new packet type SILC_PACKET_FTP and defined File Transfer
2739 Payload. The mandatory file transfer protocol is SFTP
2740 (SSH File Transfer Protocol). Affected file in addition
2741 of the internet draft is lib/silccore/silcpacket.h.
2743 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2744 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2745 is used as part of backup router protocol when the primary
2746 router of the cell is back online and wishes to resume
2747 the position as primary router.
2749 * Redefined the MAC generation keys in the protocol. The
2750 same key is not used anymore in both direction. Both
2751 direction will now use different keys for sending and
2752 receiving. This fixes a potential security flaw. This
2753 change causes incompatibilities in the protocol.
2755 * Redefined also the MAC computation from the packet.
2756 An packet sequence number is now added to the MAC
2757 computation. This prevents possible replay attacks against
2758 the protocol. This change too causes incompatibilities
2761 Added `sequence' field to the SilcPacketContext to hold
2762 the current sequence number for the packet.
2764 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * Added `created' field to the SilcIDListData in the file
2767 silcd/idlist.h to indicate the time when the entry was
2770 * Added `created' field to the SilcChannelEntry too. Affected
2771 file silcd/idlist.h.
2773 * Added `creation_time' aguments to all the announcement functions
2774 in the server. If it is provided then only the entries that
2775 was created after the provided time frame are actually
2776 announced. Affected file silcd/server.[ch].
2778 * The protocol says that the Channel ID's IP address must be
2779 based on the router's IP address. Added check for this in
2780 the silc_server_new_channel when processing incoming New Channel
2781 Payload. Affected file silcd/packet_receive.c.
2783 * Print out the correct version with --version in SILC client.
2784 Affected file irssi/src/silc/core/silc-core.c.
2786 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * Fixed WHOWAS command to check for completnes of the client
2789 entry always, not just when the command is coming from client.
2790 Affected file silcd/command.c.
2792 * Added new function silc_server_packet_queue_purge to purge the
2793 outgoing data queue to the network. After the function returns
2794 it is guaranteed that the outgoing packet queue is empty.
2795 Affected file silcd/packet_send.[ch].
2797 * Purge the outgoing packet queue in the rekey protocol's final
2798 callback to assure that all rekey packets go to the network
2799 before quitting the protocol. Affected file silcd/server.c.
2801 * Added silc_client_packet_queue_parse as similar function as
2802 in server to the client library. The affected file is
2803 lib/silcclient/client.c.
2805 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Splitted silcd/server.c and created silcd/server_util.[ch]
2808 for utility functions.
2810 * Added new socket flag SILC_SF_DISABLED to indicate that the
2811 connection is open but nothing can be sent to or received from
2812 the connection. Affected file lib/silcutil/silsockconn.[ch].
2813 The checking for disabled socket is checked in the low level
2814 silc_socket_write and silc_socket_read functions.
2816 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2818 * Allow only nicknames and channel names that fits into the
2819 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2821 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2823 * When processing JOIN command reply in server check that if
2824 the channel exists in our global list we'll move it the local
2825 list. Affected file silcd/command_reply.c.
2827 * Fixed the check whether client is joined on the channel already
2828 in JOIN command. Affected file lib/silcclient/command.c.
2830 * Fixed the JOIN command reply to check whether the channel
2831 already exists. Affected file lib/silcclient/command_reply.c.
2833 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2835 * Added silc_ske_status_string to map the SKE error numbers
2836 to readable strings. The affected files are
2837 lib/silcske/silcske[_status].[ch].
2839 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * Do not show the private channels on the WHOIS channel list
2842 as it is not allowed by the protocol. The affected file is
2845 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Assure that the packet length digged from the actual packet
2848 is something sensible in the silc_packet_decrypt_rest_special
2849 in lib/silccrypt/silcpacket.c.
2851 * Free and NULL the allocated pointer in silc_hmac_alloc if
2852 the HMAC allocation fails. The affected file is
2853 lib/silccrypt/silchmac.c.
2855 * Print the selected security properties to the log files in
2856 the server. Affected file silcd/protocol.c.
2858 * Add SKE's reference counter even if calling the completion
2859 callback manually. Otherwise it goes negative, although it
2860 does not cause any problems. The affected file is
2861 lib/silcske/silcske.c.
2863 * Remove the client entry with short timeout after giving the
2864 KILL command. Affected file lib/silcclient/command.c.
2866 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2867 case all found clients are already disconnected (WHOWAS would
2868 found them) in the server. Affected file silcd/command.c.
2870 * Update the last_receive (time of last data received) to be
2871 updated only when received private or channel message so that
2872 the idle time showed in WHOIS makes more sense.
2874 * Added boolean field `valid' in to the SilcClientEntry in the
2875 client library to indicate whether the entry is valid or not.
2876 This fixes the nickname change bug on channel when changing
2877 the nickname to be same than the old (like nick to Nick) the
2878 nickname formatter doesn't set the new nick anymore to Nick@host.
2879 Affected file lib/silcclient/idlist.[ch].
2881 * Now actually fixed the nickname changing on disconnection.
2882 Added new function silc_change_nick to the Irssi SILC Client.
2883 Affected file irssi/src/silc/core/client_ops.c,
2884 irssi/src/silc/core/silc-nicklist.[ch].
2886 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2888 * Check that the public key exists in the GETKEY command before
2889 trying to encode it. Affected file silcd/command.c.
2891 * Print some notifications on received public keys with GETKEY
2892 command in the Irssi SILC Client. Affected files are
2893 irssi/src/fe-common/silc/module-formats.[ch],
2894 irssi/src/silc/core/client_ops.c.
2896 * Use IDENTIFY command to resolve the server information in the
2897 GETKEY command instead of INFO command. Affected file
2898 lib/silcclient/command.c.
2900 * All command reply functions in the client library now calls
2901 the pending command reply callbacks even if an error has
2902 occurred. The server has done this a long time and now it was
2903 time to move the client library to this as well. Now all
2904 errors can be delivered back to the pending command reply
2905 callbacks if necessary. Affected files are
2906 lib/silcclient/command[_reply].[ch].
2908 * Change the nickname on disconnection back to the username
2909 because in reconnect the server will enforce it to it anyway.
2910 Affected file irssi/src/silc/core/silc-servers.c.
2912 * Fixed a config file parsing bug in the Irssi SILC client.
2913 Affected file irssi/src/silc/core/clientconfig.c.
2915 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2917 * When printing the channel mode on JOIN, verify that the
2918 channel key and channel's HMAC are valid. Affected file
2919 irssi/src/silc/core/client_ops.c.
2921 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2924 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2925 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2927 * Removed channel key rekey task deleting from the function
2928 silc_server_save_channel_key. Affected file silcd/server.c.
2929 Added explicit timeout task context instead that is used to
2930 delete the task if we are registering a new task before the
2931 new task has elapsed.
2933 * When channel key rekey occurs the client library now saves
2934 the old channel key for a short period of time (10 seconds) and
2935 is able to use it in case some is still sending channel
2936 messages encrypted with the old key after the rekey. Affected
2937 file lib/silcclient/[idlist.h|client_channel.c].
2939 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * Added check to the silc_server_new_id_real to not accept
2942 new ID if it is the sender's own ID. Affected file is
2943 silcd/packet_receive.c.
2945 * Assure that we do not announce ourself or the one we've
2946 sending our announcements when we're router and are announcing
2947 servers to our primary router. Affected file silcd/server.c.
2949 * Fixed silc_server_command_identify_check_client to assemble
2950 correct WHOIS packet. It send corrupted WHOIS packet and
2951 caused problem with router to router connections. Affected
2952 file silcd/command.c.
2954 Fixed also silc_server_command_whois_check the same way
2955 as for the IDENTIFY command.
2957 * Added new SilcIDListStatus to the server in the SilcIDListData
2958 structure. The status now includes the current status of
2959 the entry (like registered, resolved etc.). Affected file
2960 silcd/idlist.[ch]. Defined a bunch of different status types
2961 as well. This replaced the old boolean registered field as well.
2963 Added resolve_cmd_ident field to the SilcClientEntry structure
2964 too so that if the entry is for example being resolved so
2965 another command may attach to the same pending command reply
2966 without requiring to resolve the same entry again. This concept
2967 should optimize the WHOIS and the IDENTIFY resolving under
2968 heavy load by taking away unnecessary resolving for entries
2969 that are being resolved already.
2971 Added support for adding multiple pending commands for one
2972 command idenfier. Affected file silcd/command[_reply].[ch].
2974 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2975 before deleting the data. Otherwise the hash table will have
2976 freed data in comparison functions. Affected file is
2977 silcd/command_reply.c.
2979 * Fixed silc_idlist_replace_client_id to add the new entry to
2980 the cache with NULL nickname. Otherwise there will be invalid
2981 memory as the nickname after the nickname is freed. Affected
2982 file silcd/packet_receive.c.
2984 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2985 saved into wrong slots because the previous number of entries
2986 was not taken into account. Affected file silcd/idlist.c.
2987 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2989 * If we are router and we receive JOIN notify to a channel that
2990 does not have any users then notified client is marked as the
2991 channel founder, as it is it. The affected file is
2992 silcd/packet_receive.c
2994 * Added to the extended hash table API's table_del_*ext functions
2995 the destructor as argument too, so that the caller can decide
2996 which destructor to use or whether to use destructor at all.
2997 Affected file lib/silcutil/silchashtable.[ch].
2999 * Fixed ID Cache purging. It actually deleted the entries from
3000 the hash table after the data was freed. The hash table ended
3001 up comparing freed memory. The affected file is
3002 lib/silccore/silcidcache.c.
3004 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Fixed Irssi SILC client's KILL command's HELP syntax.
3008 * The USERS command now resolves the detailed user information
3009 if the userinfo field is missing. Affected file is
3010 lib/silcclient/command_reply.c.
3012 * Do not print error in silc_file_read if the read file does
3013 not exist. Just silently return NULL. Affected file is
3014 lib/silcutil/silcutil.c.
3016 * Fixed the silc_log_output to not wine about NULL filename
3017 and to not create some bogus " " filename. Affected file is
3018 lib/silcutil/silclog.c.
3020 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3022 * Fixed various printing bugs on the user interface in the
3023 Irssi SILC Client. Minor changes that were forgotten from
3026 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3028 * Fixed the configure.in.pre and the compilation and distribution
3029 environment to support the new autoconf 2.52. That version is
3030 now required to compile the CVS trunk.
3032 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3034 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3035 to generally parse user@fqdn format strings. Affected file
3036 lib/silcutil/silcutil.c.
3038 * Added nickname_format and nickname_force_format fields to the
3039 SilcClientParams structure. The first one defines the format
3040 for the nicknames that the library will enforce if the receives
3041 multiple same nicknames. The second one is boolean value and
3042 can be used to force the library to always enforce the format
3043 to the nicknames regardles whether there are multiple nicknames
3044 or not. This configurable formatting was employed to flexibly
3045 support accessing multiple nicknames from the user interface.
3046 The userinterface can now set the nicknames to what ever format
3047 they prefer. Affected file lib/silcclient/silcapi.h.
3049 Added function silc_client_nickname_format to the file
3050 lib/silcclient/idlist.c. It performs the nickname formatting.
3052 Added new field `hostname´ to the SilcClientEntry context.
3053 It holds the hostname of the client. Affected file is
3054 lib/silcclient/idlist.h.
3056 * Irssi SILC Client sets the nicknames in nick@hostn format.
3057 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3058 irssi/src/silc/core/silc-core.c.
3060 The WHOIS printing now also shows both the real nickname and
3061 the formatted nickname so that user knows how to access the
3062 user if there are multiple same nicknames cached. Affected
3063 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3064 printing formatting too to take the hostname now as a separate
3065 argument. The Affected file is
3066 irssi/src/fe-common/silc/modules-formats.[ch].
3068 * Changed the silc_client_get_clients_local to accept the formatted
3069 nickname as argument. It accepts the real nickname too but the
3070 formatted nickname can be used to find the true entry from
3071 multiple entries. Affected file lib/silcclient/silcapi.h and
3072 lib/silcclient/idlist.c.
3074 * Added nickname_format_parse field to the SilcClientParams.
3075 It is a callback function provided by the application to parse
3076 the nickname out of the formatted nickname string. The library
3077 calls it to get the nickname from the formatted string. Since
3078 the application generally knows better the format of the nickname
3079 string it parses it instead of the library, even though library
3080 encodes the formatted string. If the callback function is not
3081 provided then the library will use the string as is. The
3082 affected file is lib/silcclient/silcapi.h.
3084 * All the nickname strings passed to the client library in
3085 commands are now expected to be formatted nickname strings.
3086 If the command does not support the formatted nickname string
3087 it will assume that the sent string is the actual nickname.
3088 Affected file lib/silcclient/command.c.
3090 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3092 * Added public key authentication support to OPER and SILCOPER
3093 commands in the client library. Affected file is
3094 lib/silcclient/command.c.
3096 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3098 * Changed the get_auth_methdod client operation to be asynchronous.
3099 It can be async if the application resolves the authentication
3100 method from the server during the negotiation. Added new
3101 SilcGetAuthMeth completion callback that the application will
3102 call after resolving the authentication method.
3104 Added function silc_client_request_authentication_method that
3105 the application can use to resolve the authentication method
3106 from the server. Added also SilcConnectionAuthRequest callback
3107 that the library will call after the server has replied. The
3108 application can call this function if it does not know the
3109 current authentication method.
3111 Affected files are lib/silcclient/client.c and
3112 lib/silcclient/silcapi.h.
3114 * The Irssi SILC client now automatically resolves the authentication
3115 method incase any configuration information is not present (and
3116 currently there never is). The affected file is
3117 irssi/src/silc/core/client_ops.c.
3119 * Fixed public key authentication from the client library.
3120 Affected file lib/silcclient/protocol.c. Changed also the
3121 protocol specification about the public key authentication in
3122 the connection authentication protocol. The actual data to be
3123 signed is now computed with a hash function before signing.
3125 * Fixed the public key authentication from the server as well.
3126 Affected file silcd/protocol.c.
3128 * Removed the mlock()'s from the memory allocation routines.
3129 Affected file lib/silcutil/silcmemory.c. The ./configure does
3130 not check anymore for the mlock(). Affected file is
3133 * Fixed USERS command in server to allow the execution of the
3134 command for private and secret channels if the client sending
3135 the command is on the channel. Affected file silcd/command.c.
3137 * Fixed silc_client_get_clients_local to return the clients
3138 count correctly. It could return wrong value. Affected file
3139 lib/silcclient/idlist.c.
3141 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3143 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3144 types. The assembler optimizations seemed not to like 64-bit
3145 data types. The assmebler optimizations thus are now enabled
3146 also for BSD systems as opposed to only enable them for Linux.
3148 * Do not check for threads at all on BSD systems. Affected
3149 file configure.in.pre.
3151 * Removed -n and -h options from the Irssi SILC Client since
3152 they are not used in silc.
3154 * Fixed the prime generation to assure that the first digit
3155 of the generated random number is not zero since our conversion
3156 routines does not like number strings that starts with zero
3157 digit. If zero digit is seen the random number is regenerated.
3158 This caused some corrupted RSA keys when the zero first digit
3159 was met. Affected file lib/silcmath/silcprimegen.c.
3161 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3163 * Fixed WIN32 configuration in the ./configure script.
3164 Fixed to include xti.h on environments that has it.
3165 Patches by Carsten Ilchmann and andrew.
3167 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3169 * Changed the silc_id_create_client_id to be collision
3170 resistant. It is now assured that there cannot be created
3171 two same client ID's. I suspect that some weird bugs in
3172 the server were actually caused by duplicate Client IDs.
3173 Affected file silcd/serverid.[ch]. A router receiving
3174 new ID now also assures and informs the sending server
3175 if the ID caused collision.
3177 * Changed the silc_id_create_channel_id to also assure that
3178 there are no collisions.
3180 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * Statement about ignoring the Mutual Authentication flag when
3183 performing rekey with PFS was a bit misleading. It is ignored
3184 if it was set in the initial negotiation, it cannot be even
3185 set in the rekey. Fixed in the ke-auth draft. Started the
3186 new versions of the protocol drafts in the doc/.
3188 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * Fixed a bug in silc_client_command_identify_save when saving
3191 new channel information. The channel name was no duplicated
3192 and caused crash on exit. Affected file is
3193 lib/silcclient/command_reply.c.
3195 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3197 * Fixed the getkey command handling in the server. Send just
3198 empty OK reply to the sender if the key could not be fetched
3199 (but everything else was ok, like the key just was not available).
3200 Changed the public key parameter to optional in the protocol
3201 specs so that empty OK reply can be sent. Affected file
3204 Added a message to Irssi SILC client to tell to user if the
3205 server did not return a public key.
3207 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3209 * Fixed a channel key regeneration bug. It registered new
3210 timeout tasks exponentially until all system resources were
3211 used. Affected file silcd/server.c.
3213 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3215 * Added the SILC Document generator to the scripts/silcdoc.
3216 It can be used to generate the Toolkit Reference Manual out
3217 of the source tree. Internally it will also use the RoboDoc
3218 generator now imported in util/robodoc.
3220 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3222 * Added couple of return's in rekey protocol if error orccurred
3223 during the protocol. The execution must be terminated.
3224 Affected file silcd/protocol.c. Also, terminate the protocol
3225 always with timeout.
3227 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * The client's Client ID was created initally from the wrong
3230 nickname (it could have been in format nick@host) in the
3231 silc_server_new_client. Affected file silcd/packet_receive.c
3233 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * Added some SILC_LOG_ERROR's to various error conditions
3236 if client could not be added to ID cache. Affected files
3237 silcd/packet_receive.c and silcd/server.c.
3239 * When client's sock->user_data is freed, NULL also the
3240 client->router and client->connection pointers. Added check
3241 for these pointers being NULL to various places around the
3242 code. Affected file silcd/server.c.
3244 * Added client->data.registered == TRUE checks to various
3245 places around the code to assure that unregistered client's
3246 are not handled when it is not allowed. Affected file
3249 * Added `bool registered' fields to all
3250 silc_idlist_[server|client]_get_* routines to indicate whether
3251 the fetched client needs to be registered or not. Affected
3252 file silcd/idlist.[ch].
3254 * Add your own entry as registered to the ID cache in the
3255 server. Affected file server.c.
3257 * Fixed a bug in silc_server_new_server. The SilcServer was
3258 set as the new server's context instead of SilcServerEntry.
3259 This naturally caused some weird bugs.
3261 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3263 * Do not delete the channel rekey task when adding it
3264 for in silc_server_create_channel_key.
3266 * Changed the silc_server_create_channel_key to return
3267 TRUE or FALSE to indicate the success of the channel key
3270 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3272 * Fixed MSVC++ project files and added missing files to
3273 Makefiles under win32/.
3275 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3277 * Do not add TCP_NODELAY flag if the operating system
3278 does not have it defined. Affected files are
3279 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3281 * Fixed buffer overflow from Irssi SILC Client. Affected
3282 file irssi/src/fe-common/core/themes.c.
3284 * Fixed double free in client library in the file
3285 lib/silcclient/client.c when disconnecting from server.
3287 * Applied double free patch from cras to Irssi SILC client.
3288 Affected files irssi/src/core/[modules/expandos].c
3290 * Fixed the disconnection handling to Irssi SILC Client.
3291 The application must call silc_client_close_connection
3292 in ops->connect client operation in case of failure of
3293 the connection. Affected file is
3294 irssi/src/silc/core/client_ops.c.
3296 * Do not set sock->protocol to NULL in the function
3297 silc_client_close_connection after executing the protocol's
3298 final callback since the sock might not be valid anymore.
3299 Affected file lib/silcclient/client.c.
3301 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3303 * Do not enable SILC_THREADS if the linking with libpthread
3304 did not happen. Affected file configure.in.pre.
3306 * Added notion to protocol specification that server must
3307 verify the sent authentication payload with CMODE when
3308 setting the channel founder key. Implemented it to the
3309 server. Affected file silcd/command.c.
3311 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3313 * Added _EXTRA_DIST SILC distribution variable to the
3314 distributions file. It is used to conditionally add extra
3315 files or directories to the specific distribution. Affected
3316 files ./prepare, Makefile.am.pre and distributions.
3318 Removed the `_' from the start of the distribution names.
3321 * Added README.WIN32 for instructions to compile the Toolkit
3324 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3326 * Fixed a double free in disconnection in the server. Affected
3327 file is silcd/server.c.
3329 * Fixed the lib/silcske/groups.c to work now also with GMP
3330 MP library. The string conversion did not work when using
3331 specific base and the base is indicated in the string as well.
3333 * Created win32/ directory which now includes MSVC++ specific
3334 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3335 It will appear only in the toolkit distribution
3337 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3339 * Changed the key material distribution function in case when
3340 the hash output is too short. The data is now concatenated
3341 a bit differently than it used to. Made the change to the
3342 SKE protocol specification.
3344 * Added better GMP detection to configure.in.pre. A patch
3347 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3349 * Fixed a minor bug in SKE that might cause some problem on
3350 some platforms. Affected file lib/silcske/silcske.c.
3352 * Added the cookie checking for initiator in the SKE. It checks
3353 that the responder returns the sent cookie unmodified. The
3354 affected file is lib/silcske/silcske.c. Added new SKE
3355 error type INVALID_COOKIE that can be sent during the
3356 negotiation. Fixed some memory leaks as well.
3358 * Added the "invalid cookie" error message to Irssi SILC client's
3361 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3363 * Added `task_max' field to the SilcClientParams to indicate
3364 the maximum tasks the scheduler can handle. If set to zero,
3365 default values are used. Affected file lib/silcclient/silcapi.h.
3367 * Fixed memory leaks in silc_client_close_connection. Affected
3368 file lib/silcclient/client.c.
3370 * Added silc_client_del_client_entry to client library to free
3371 all memory of given client entry. Affected file is
3372 lib/silcclient/idlist.[ch].
3374 * Added new functions silc_client_del_channel and
3375 silc_client_del_server to delete channel and server entries.
3376 Affected file lib/silcclient/[silcapi.h/idlist.c].
3378 * Removed silc_client_del_client_by_id from silcapi.h.
3380 * Fixed the INFO command to return the server's own info
3381 correctly when querying by Server ID. Affected file is
3384 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3386 * Removed the non-blocking settings in WIN32 code in the
3387 silc_sock_[read/write] and added SleepEx instead. Affected
3388 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3389 of input data is now checked with FIONREAD and ioctlsocket.
3391 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3393 * Call silc_schedule_task_del_by_context in the
3394 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3395 Affected file lib/silccore/silcprotocol.c.
3397 * Call silc_protocol_cancel for active protocols in the
3398 silc_server_close_connection if the funtion
3399 silc_server_free_sock_user_data has not been called.
3400 Affected file silcd/server.c.
3402 * Generic tasks cannot be deleted using the del_by_fd
3403 task deleting function since generic tasks does not match
3404 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3406 * Added a notion to SILCOPER help file that the SILCOPER works
3407 only on router server, not on normal server.
3409 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3411 * Added for WIN32 support for the new scheduler as well.
3412 Affected file lib/silcutil/win32/silcwin32schedule.c.
3414 * Fixed the SHA1 implementation to work on various platforms.
3416 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3418 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3419 API. It is part of the scheduler now. Everything else is
3420 as previously but some functions has changed their names.
3421 Checkout the lib/silcutil/silcschedule.h for the interface.
3422 Updated all applications to use the new interface. Affected
3423 files are lib/silcutil/silcschedule.[ch].
3425 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3427 * Found a bug in the SKE implementation. The HASH value,
3428 specified by the protocol, was not computed correctly. The
3429 public key of the responder was not added to the computation
3430 even though it is mandatory. Affected file lib/silcske/silcske.c.
3431 This unfortunately causes incompatibilities with older
3432 clients and servers.
3434 * Added WIN32 specific network init and uninit functions:
3435 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3436 the Winsock2. Affected file lib/silcutil/silcnet.h and
3437 lib/silcutil/win32/silcwin32net.c.
3439 * Set the socket always to nonblocking mode on WIN32 after
3440 reading data or writing data. Affected file is
3441 lib/silcutil/win32/silcwin32sockconn.c.
3443 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3445 * Fixed various compilation problems under WIN32. Affected
3446 files lib/silcutil/win32/silcwin32thread.c and
3447 lib/silcutil/win32/silcwin32schedule.c.
3449 * Removed all _internal.h #includes from public header
3450 files. Internal headers must never be included from
3453 Removed also the lib/silcske/payload_internal.h file.
3455 * All include files that may be needed (public and some others
3456 included by the public headers) by application developers are
3457 now copied to the ./includes directory. It does not copy any
3458 internal headers. Affected file Makefile.defines.pre and all
3459 Makefile.am's under lib/ and subdirs.
3461 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3463 * Do not change the ~/.silc directory's permissions automatically.
3464 Affected file irssi/src/silc/core/clientutil.c.
3466 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3468 * Do not cancel the protocol in silc_server_close_connection
3469 it might cause recursion. Now cancelled in the function
3470 silc_server_free_sock_user_data. Affected file silcd/server.c.
3472 * Fixed the silc_server_remove_clients_by_server to regenerate
3473 the channel keys correctly finally. Added also new function
3474 silc_server_remove_clients_channels to actually do it.
3475 Affected file silcd/server.c.
3477 * Fixed the silc_server_new_channel to not crash by giving
3478 wrong router to the new channel. Affected file is
3479 silcd/packet_receive.c.
3481 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3483 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3484 which is given as argument to the silc_client_alloc now.
3485 It can be used to configure the client and set various parameters
3486 that affect the function of the client.
3488 * The USERS command in server did not check whether the channel
3489 is private or secret. Affected file silcd/command.c.
3491 * Added new argument to the USERS command in protocol specification.
3492 The USERS command now can take the channel name as argument
3493 as well. Added support for this in client and server and
3494 updated the protocol specs.
3496 * Completed the GETKEY command in client. It can be now used
3497 to fetch also servers public key not only some clients.
3498 Affected files lib/silcclient/command[_reply].c.
3500 * Added silc_client_get_server to return server entry by the
3501 server name. Affected files lib/silcclient/silcapi.h and
3504 * Redefined the IDENTIFY command in protocol specification to be
3505 more generic. It now can be used to query information about
3506 any entity in the SILC Network, including clients, servers and
3507 channels. The query may be based either the entity's name
3508 or the ID. Added support for this in both client and server.
3510 Affected files silcd/command.c and lib/silcclient/command.c
3511 and command_reply.c.
3513 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3514 the _from_client and _from_server functions. Affected file
3517 * Added silc_client_get_channel_by_id_resolve to the file
3518 lib/silcclient/silcapi.h to resolve channel information by
3519 its ID. Added also silc_client_get_channel_by_id that
3520 does not resolve it from the server.
3522 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3524 * Added SilcServerEntry context into the client library
3525 to represent one server. The INFO command now allocates
3526 these to save the resolved server info. For now on the
3527 client library will also keep information about servers,
3528 connected and resolved with INFO.
3530 The INFO command now allocates the SilcServerEntry context
3531 and saves the server info there. The COMMAND_REPLY in
3532 the INFO now returns the parameters to application in
3533 same order as defined in the protocol specification.
3535 The entries are cached in the client->server_cache.
3537 * The INFO command is now issued after received the Client ID
3538 from the server. Affected file lib/silcclient/client.c.
3540 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3541 to the application as the mode changer might be server.
3542 It is guaranteed that NULL is not returned anymore to the
3543 application. Affected file lib/silcclient/client_notify.c.
3545 The ID Type is now also passed to the application so that
3546 it can check whether the returned entry is SilcClientEntry
3549 Added new function silc_client_get_server_by_id to return
3550 the server entry by ID. Affected files are the
3551 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3553 * Do not create the channel in the Irssi SILC Client when issuing
3554 the JOIN command but when received the sucessful JOIN command
3555 reply. Otherwise the channel might get created even though we
3556 could not join it. The Affected file is
3557 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3559 * Fixed a channel joining bug in router. The router must also
3560 check the channel modes, invite and ban lists etc. when serving
3561 the JOIN command sent by normal server. Affected file is
3562 silcd/command.c. The router now resolves the client's
3563 information from the server who sent the JOIN command if it
3564 does not know it, and processes the JOIN command only after
3567 * Changed the SilcCommandCb to take new argument; void *context2.
3568 Affected file lib/silccore/silccommand.h
3570 The second argument in the command callbacks in the server now
3571 includes the SilcServerCommandReplyContext if the command was
3572 called as pending command callback from the command reply.
3573 Otherwise it is NULL. When called as pending the status of the
3574 command reply will be checked and if it was erronous the
3575 error will be sent to the original sender of the command.
3576 This way the client always receives the error messages even
3577 though the server was actually the one who received the error
3578 when it resent the command to router, for example. Affected
3579 files silcd/command[_reply].[ch].
3581 * Fixed sending WHOWAS command's error message to client if
3582 the requested client could not be found. It was missing.
3585 * Changed the CMODE and CUMODE commands reply arguments in the
3586 protocol specification. The Channel ID is now sent in both
3587 of the commands to identify the channel. Implemented this
3588 new feature to the client and server. Affected files
3589 lib/silcclient/command_reply.c and silcd/command.c.
3591 * Made better checks for invite and ban lists in the JOIN
3592 command in server. Affected file silcd/command.c.
3594 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3596 * The server now performs the incoming host IP/DNS lookup
3597 using the silc_socket_host_lookup and thus does not block
3598 the server anymore. Affected file silcd/server.c.
3600 * Completed the multi-thread support for SILC Scheduler in
3601 the lib/silcutil/silcschedule.c.
3603 * Fixed the configure.in.pre to detect the pthread correctly
3606 * Fixed a deadlock in silc_task_queue_wakeup in the file
3607 lib/silcutil/silctask.c.
3609 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3611 * Added new function silc_schedule_wakeup that is used in
3612 multi-threaded environment to wakeup the main thread's
3613 schduler. It needs to be used when a thread adds a new task
3614 or removes a task from task queues. After waking up, the
3615 scheduler will detect the task queue changes. If threads
3616 support is not compiled in this function has no effect.
3617 Implemented the wakeup mechanism to both Unix and WIN32
3618 systems. Affected files are lib/silcutil/silcschedule.[ch],
3619 lib/silcutil/unix/silcunixschedule.c and the
3620 lib/silcutil/win32/silcwin32schedule.c.
3622 * Added new function silc_task_queue_wakeup to wakeup the
3623 scheduler by the specified task queue. Affected file
3624 lib/silcutil/silctask.[ch].
3626 * The silc_socket_host_lookup_start now wakes up the scheduler
3627 after adding the timeout task. Affected file is
3628 lib/silcutil/silcsockconn.c.
3630 * The silc_socket_host_lookup is synchronous now if the threads
3631 support is not compiled in. However, the callback is still
3632 called asyncronously through the scheduler, anyway. Affected
3633 file lib/silcutil/silcsockconn.c.
3635 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3637 * Added new function silc_socket_host_lookup to perform
3638 asynchronous IP and FQDN lookups for the socket connection.
3639 Affected files lib/silcutil/silcsockconn.[ch].
3641 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3643 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3644 that may or may not compile the mutex support in.
3646 Changed the silc_mutex_alloc interface. It allocates the
3647 mutex now to the sent pointer and returns TRUE or FALSE.
3649 Affected file lib/silcutil/silcmutex.h.
3651 * Wrote the SILC Task Queue interface to support multi-threads.
3652 Affected file lib/silcutil/silctask.[ch].
3654 * Wrote the SILC Scheduler to support multi-threads. Affected
3655 file lib/silcutil/silcschedule.c.
3657 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3659 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3660 in lib/silcutil/win32/.
3662 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3664 * Defined SILC Mutex API and SILC Thread API and implemented
3665 them for Unix. Affected files are
3666 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3667 lib/silcutil/unix/silcunixmutex.c and
3668 lib/silcutil/unix/silcunixthread.c.
3670 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3672 * Fixed the silc_server_remove_clients_by_server's channel
3673 key re-generation. The hash table handling was incorrect
3674 and would not work with many channels. Affected file is
3677 * Fixed some memory leaks around the server code.
3679 * Rewrote the silc_server_get_users_on_channel to support IPv6
3680 based Client ID's. Affected file silcd/server.c.
3682 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3683 specification. However, a separate document must be written
3684 to define the detailed signing procedure and the payload
3685 associated with the flag. Defined the flag to the
3686 lib/silccore/silcchannel.h as well.
3688 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3690 * Changed the dynamic tables to static size tables in the
3691 lib/silccrypt/silchmac.c.
3693 * Removed GCC dependencies from the code. A patch by cras.
3695 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3697 * Do not show the error "Error receiving packet bla bla"
3698 in server if it really was not an error (-2 means that reading
3699 is pending). Affected file silcd/server.c.
3701 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3703 * Fixed a possible crash in silc_server_remove_clients_by_server
3704 in silcd/server.c. Fixed there also some memory leaks.
3706 * Fixed the silc_idlist_replace_client_id. It could replace
3707 wrong key in the hash table. Affected file silcd/idlist.c.
3709 * Do not check whether there are global users on the channel
3710 if the channel->global_users is FALSE. Affected functions
3711 silc_server_remove_from_one_channel and
3712 silc_server_remove_from_channels in silcd/server.c. Also,
3713 do not check if the removed client is local as we can be
3714 sure that global client was not removed from the channel
3715 and checking for global users is not needed.
3717 * The silc_server_remove_clients_by_server now re-generates
3718 the channel keys correctly for those channels that had
3719 clients removed from them. Affected file silcd/server.c.
3721 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3723 * Found the reason of random crashes in the server. We weren't
3724 ignoring the SIGPIPE signal (which can be sent in write())
3725 and it crashed the server. Affected file silcd/silcd.c.
3727 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3729 * Assure that sock->user_data is not NULL in the function
3730 silc_server_packet_send in silcd/packet_send.c.
3732 * Disconnect the remote connection if it could not be added
3733 to any ID lists in the server. The affected file is
3736 * Check in silc_server_packet_send[_real/dest] that the
3737 socket is not disconnecting and ignore the data if it is.
3738 Affected file silcd/packet_send.c.
3740 * Define inline to __inline on native WIN32 compilation.
3741 Affected file includes/silcwin32.h.
3743 * Added some explicit type casts for inline code since MSVC
3744 require them. Affected files lib/silcutil/silcbuffer.h,
3745 lib/trq/silcdlist.h and lib/trq/silclist.h.
3747 * Print warning in log files from now on if the packet
3748 decryption fails. Affected file silcd/server.c.
3750 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3752 * Changed the `say' client operation's interface to accept
3753 new `type' argument to indicate the type of the message sent
3754 by the library. The application may filter the library's
3755 messages according the type. The affected file is the
3756 lib/silcclient/silcapi.h.
3758 * Added two new functions to lib/silcclient/silcapi.h:
3759 silc_client_del_client and silc_client_del_client_by_id.
3760 Affected file lib/silcclient/idlist.c.
3762 * Moved the clientincludes.h from includes/ to silc/ and
3763 serverincludes.h from includes/ to silcd/.
3765 * The modes for the CMODE and CUMODE are now passed as
3766 uint32 for application with COMMAND_REPLY. The affected
3767 file is lib/silcclient/command_reply.c.
3769 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3771 * /WHOIS without arguments shows client's own information.
3772 Affected file lib/silcclient/command.c.
3774 * Changed PING to not accept any arguments. The specs
3775 says that client can ping only the connected server so
3776 requiring an argument is not needed. Affected file is
3777 lib/silcclient/command.c.
3779 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3781 * Fixed a fatal bug in private message sending and reception
3782 encryption and decryption when using private message keys.
3783 The implementation was incorrect and did not follow the
3784 specification. It causd that some of the message were
3785 lost since it did not use the sending and receiving keys
3786 as the protocol suggests. This has been fixed and will cause
3787 incompatibilities with older clients when sending private
3788 message encrypted with private message keys. Affected files
3789 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3790 and various other in Irssi SILC Client.
3792 Added `responder' boolean argument to the functions
3793 silc_client_add_private_message_key[_ske] to indicate when
3794 the key is added as responder or initiator of the key
3797 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3799 * Removed the silc_ske_check_version function and created
3800 a SilcSKECheckVersion callback. Added also a function
3801 silc_ske_set_callbacks that is now used to set all SKE
3802 callbacks. The callback functions are not given to
3803 the SKE functions anymore, but this function is used to
3806 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3808 * Added `silc_version' argument to the silc_client_alloc
3809 to define the version of the application for the library.
3810 The library will use the version string to compare it
3811 against the remote host's (usually a server) version
3812 string. Affected file lib/silcclient/silcapi.h
3814 * Added the KE protocol context to Key Agreement context
3815 in client library so that we can abort the SKE if it
3816 is in process when we get timeout. Affected file is
3817 lib/silcclient/client_keyagr.c.
3819 * Do not resolve the client ID forever if it returns in the
3820 first time that such client does not exist. This was done
3821 for example with private message. Affected file is
3822 lib/silcclient/client_prvmsg.c.
3824 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3826 * Do not add regex.h for WIN32. The affected file
3827 includes/silcincludes.h.
3829 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3830 not work yet 100%. It generates the DLL's automatically
3831 when compiling with --with-win32 under cygwin.
3833 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3835 * lib/contrib/regex.c is not compiled on WIN32.
3837 * Added silc_net_get_socket_opt function to the
3838 lib/silcutil/silcnet.h.
3840 * Added includes/silcwin32.h for WIN32 specific includes
3843 * Do not use ptime structure or any of the posix process
3844 functions on WIN32 in lib/silccrypt/silrng.c.
3846 * Added silc_gettimeofday to provide generic function
3847 for struct timeval on all platforms. Added the function
3848 to lib/silcutil/silcutil.h.
3850 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3852 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3853 library as they clearly belong there. As a plus side we
3854 can make the actual socket connection routines platform
3857 Added also new generic function silc_socket_read and
3858 silc_socket_write (that used to be silc_packet_[read/write].
3859 The implementation of these are platform specific.
3861 * Added WIN32 specific routines of silc_socket_[read/write]
3862 to lib/silcutil/win32/silcwin32sockconn.c.
3864 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3866 * Added preliminary support for native WIN32 compilation under
3867 cygwin (using the -mno-cygwin option for GCC) to the
3868 ./configure.in.pre. The --with-win32 now prepares the
3869 compilation for native WIN32.
3871 * Rewrote the SILC Scheduler interface in the file
3872 lib/silcutil/silcschedule.h. The scheduler is now context
3873 based and does not have anymore any global static scheduler.
3874 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3875 and created lib/silcutil/win32 directory for WIN32 based
3878 * Added Unix specific network routines to the
3879 lib/silcutil/unix/silcunixnet.c and the old
3880 lib/silcutil/silcnet.c includes now only generic routines.
3882 Added WIN32 specific network routines to the
3883 lib/silcutil/win32/silcwin32net.c.
3885 * Added Unix specific utility functions from the
3886 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3888 * Added WIN32 SILC Scheduler to the file
3889 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3892 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3894 * Do not handle JOIN notify in the server if the target client
3895 is not registered (idata->registered == FALSE). The affected
3896 file is silcd/packet_receive.c.
3898 * Update the nickrec->founder in event_cumode in the Irssi SILC
3899 client. Affected file irssi/src/silc/core/silc-channels.c.
3901 * Fixed the CUMODE_CHANGE notify handling in the server when
3902 server and router are announcing their clients on channels.
3903 Now the mode changes are saved and notified correctly. The
3904 affected file is /silcd/packet_receive.c.
3906 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3907 They really did not replace the cache entry in the ID Cache.
3908 Now they do that. Affected file silcd/idlist.c.
3910 * Fixed the KICK notify handling in the Irssi SILC client to
3911 update the channel records so that the kicked client does not
3912 appear to be on the channel. The affected file is
3913 irssi/src/silc/core/silc-channels.c.
3915 * Always update the conn->current_channel when executing command
3916 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3918 * Fixed the KILL notify handling in Irssi SILC client to remove
3919 the killed client on all channels.
3921 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3923 * Fixed the silc_parse_command_line to remove extra spaces
3924 from the start and end of the arguments. Affected file is
3925 lib/silcutil/silcutil.c.
3927 * Cancel and free any active protocol in the function
3928 silc_server_close_connection. Affected file silcd/server.c.
3930 * Cancel and free any active protocol in the function
3931 silc_client_close_connction. Affected file is
3932 lib/silcclient/client.c.
3934 * Do not execute the KILL command for clients that are in
3935 history (ie. they are not in the network). Affected file is
3938 * Fixed KILL notify handling, client does not crash anymore.
3939 Affected file irssi/src/silc/core/silc-channels.c.
3941 * Reduced the default packet buffer size from 2048 to 1024 in
3942 lib/silccore/silcpacket.c.
3944 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3945 counter to the SKE context that is incresed when the SKE library
3946 performs async operation outside the library. If the outside
3947 process frees the SKE context and FREED status will be set
3948 and the library will detect after the sync operation that the
3949 libary is freed. The affected files are
3950 lib/silcske/silcske[_status].[ch].
3952 * Resolve the client entry information in the function
3953 silc_client_channel_message to assure that NULL pointer is not
3954 passed as client entry to the application. */
3956 * Fixed the task timeout calculation to assure that there is
3957 never negative timeouts. The affected file is
3958 lib/silcutil/silcschedule.c.
3960 * Fixed the channel user mode notification sending in server.
3961 It was sent point-to-point to the router (or to server by router)
3962 but it needs to be destined to a channel. The routines now
3963 supports sending the channel user mode notifys to the channels
3964 when announcing clients and channels. Affected files are
3965 silcd/server.c and silcd/packet_receive.c.
3967 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3968 It did not actually replace the old channel entry in the cache.
3969 Affected file lib/silcclient/client_notify.c.
3971 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Fixed a possible crash in silc_packet_send_prepare. It now
3974 assures always that there is enough space in the buffer and
3975 at the tail area of the buffer (for MAC).
3977 Fixed the inbound buffer reallocation in silc_packet_read.
3978 It was old code and did not handle the reallocation correctly.
3981 The affected file is lib/silccore/silcpacket.c.
3983 * Fixed buffer overflow in silc_parse_nickname in the file
3984 lib/silcutil/silcutil.c.
3986 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * make install generates new server keys only if there is not
3991 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3994 Added check that if the NOREPLY is set then we will not send
3995 the away message. This avoids infinite loop of away messages
3996 if both clients are away. The affected file is
3997 lib/silcclient/client_prvmsg.c.
3999 * Fixed client crash if /NICK was given without arguments.
4000 Affected file lib/silcclient/command.c.
4002 * Server does not send the invite list in INVITE command back
4003 to the client if the list was not altered. Added this notion
4004 to the protocol spec as well. Affected file silcd/command.c.
4006 Fixed possible crash in INVITE command by checking the
4007 value of silc_server_get_client_route command.
4009 * Fixed the INVITE notify type handling. The arguments are now
4010 taken in correct order and client does not crash. The affected
4011 file is irssi/src/silc/core/silc-channels.c.
4013 Removed the "Inviting xxx to channel" message from the
4014 client library away and let the application handle it.
4015 Affected file lib/silcclient/command.c. Added that message
4016 to Irssi SILC client's message formats.
4018 * Fixed CMODE command crash in client. It now checks the
4019 amount of arguments correctly and does not crash. The affected
4020 file is lib/silcclient/command.c.
4022 * Do not create new channel automatically in silc_channels_join
4023 but check whether the channel by that name already exists.
4024 Affected file irssi/silc/core/silc-channels.c.
4026 * Do not send the SERVER_SIGNOFF to router if the disconnected
4027 entity was the router. Affected file silcd/server.c.
4029 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4030 SILC client as it was missing from there.
4032 Added the handling of the KICK notify to the Irssi SILC client
4033 as it was missing. Added "you have been kicked" message to
4034 Irssi SILC client's message modules formats.
4036 Added the handing of the KILL notify to the Irssi SILC client
4037 as it was missing. Added the kill message module formats
4040 The affected file is irssi/src/silc/core/silc-channels.c.
4042 * The router did not save the channel mode the server announced.
4043 Affected file silcd/packet_receive.c.
4045 * Fixed a possible crash in INFO command in server. If the
4046 server did not provide the server info it crashed. Affected
4047 file silcd/command.c.
4049 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Fixed the GETKEY command in the server to check also the
4052 global list. Otherwise the GETKEY would not work correctly
4053 in normal SILC server. Affected file silcd/command.c.
4055 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4057 * Fixed GETKEY crash, it crashed if the command did not succseed.
4059 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4062 is now real and not just an macro interface to GMP.
4064 Removed the entire GMP from the source tree and imported new
4065 NSS MPI library instead. Reason for removing GMP is that it is
4066 extremely large and compiles extremely slow. The NSS MPI
4067 is only a few files and compiles in less than 10 seconds.
4068 The speed is also about the same as GMP. The MPI is imported
4069 to lib/silcmath/mpi.
4071 If the system has GMP installed we will still use the GMP.
4072 If it is not then the NSS MPI will be compiled.
4074 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4076 * Merged a long nickname (127 characters long) crash bugfix from
4077 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4079 * Merged a freed memory reference bugfix from Irssi CVS tree.
4080 Affected file irssi/src/core/commands.c.
4082 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Added the server's public key sving and verification to the
4085 server when performing the SKE. This was missing and the
4086 remote server's (or router's) public key was accepted without
4087 checking whether we have it previously or trust it at all.
4088 Affected file silcd/protocol.c.
4090 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * Check in the silc_server_timeout_remote if protocol is active
4093 and make sure that the protocol's final callback is called so
4094 that all memory if freed. Affected file silcd/server.c.
4096 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * silc_server_whois_send_reply crashed the server if the nickname
4099 was 127 characters long. Affected file silcd/command.c.
4101 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Added sanity check to the silc_server_new_client. If the hostname
4104 is provided inside username then check that the provided hostname
4105 really is the same as the resolved one. If the hostname was not
4106 resolved then check it from the public key. Affected file is
4107 silcd/packet_receive.c.
4109 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4110 if the server disconnected us and the connection is not valid
4111 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4113 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4114 the library to the lib/silcutil/silcutil.[ch].
4116 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4118 * Close log file after open. Affected file
4119 lib/silcutil/silclog.c.
4121 * Check whether sock == NULL in silc_client_send_packet and return
4122 if it is. Affected file lib/silcclient/silcclient.c.
4124 * Check rec->entry == NULL in the Irssi SILC Client before
4125 sending the channel message. Affecte file is
4126 irssi/src/silc/core/silc-servers.c.
4128 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Merged a splitted window bugfix from Irssi CVS tree. The
4131 affected file is irssi/src/fe-text/textbuffer-view.c.
4133 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4134 It did not print nickname.
4136 * Improved the distributions system a bit.
4138 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4141 irssi/src/fe-text/gui-window.c.
4143 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4144 to in-active server. The affected file is
4145 irssi/src/silc/core/client_ops.c.
4147 * Resolve the client in USERS command reply if the entry does
4148 not have username resolved. The affected file is
4149 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4150 command to WHOIS command to really resolve stuff. The USERS
4151 is not used any more in any critical section so WHOIS can
4152 be used even though it might be slower than IDENTIFY.
4154 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4157 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Changed the protocol API a bit more consistent in the
4160 lib/silccore/silcprotocol.[ch].
4162 * Changed the following headers to ROBODoc format:
4164 lib/silccore/silcpayload.h
4165 lib/silccore/silcprotocol.h
4166 lib/silccore/silcsockconn.h
4168 All core library headers are now formatted.
4170 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Fixed a bug in Irssi SILC client; do not show that you are
4173 server/router operator if you really are not. Affected file is
4174 irssi/src/silc/core/client_ops.c.
4176 * Renamed silc_command_free_payload to silc_command_payload_free.
4177 Affected file lib/silccore/silccommand.h
4179 * Added silcmath.h to include the prototoypes of various routines
4180 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4183 * Changed the following headers to ROBODoc format:
4185 lib/silccore/silcchannel.h
4186 lib/silccore/silccommand.h
4187 lib/silccore/silcid.h
4188 lib/silccore/silcidcache.h
4189 lib/silccore/silcmode.h
4190 lib/silccore/silcnotify.h
4191 lib/silccore/silcpacket.h
4192 lib/silcmath/silcmath.h
4194 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Added checking to the server code not to start the server if
4197 ciphers and stuff are not configured properly. Affected files
4198 silcd/serverconfig.[h] and silcd/server.c.
4200 * Changed the layout of the header files of the public interfaces
4201 in the SILC libraries. The new layout supports ROBODoc
4202 documentation tool (and some others) so that it is easy to create
4203 a library reference manual. All the other headers and source
4204 code must still follow the CodingStyle document. Also source
4205 code must not include these ROBODoc stuffs, only the headers.
4206 Furthermore, all public interface headers must now be named
4207 by using `silc' prefix, example: silcapi.h, silccipher.h.
4208 Some files were renamed due to this. All the other headers
4209 must not be used as public interfaces. I will update the
4210 CodingStyle document later. Changed following headers, so far:
4212 lib/silcclient/silcapi.h
4213 lib/silccore/silcauth.h
4214 lib/silccore/silcprivate.h
4215 lib/silccrypt/silcdh.h
4217 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Removed silc_client_packet_send_flush from the client library
4222 as it is not needed. Affected file lib/silcclient/client.[ch].
4224 * Added printing of message of unresolved authentication method
4225 to the Irssi SILC client. Added it to the module formats.
4226 Removed the same message from the client library.
4228 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Added new distribution feature, DISTLABEL. Every distribution
4231 can define own preprocessor label that can be used in the
4232 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4233 file distributions, acconfig.h.pre and prepare.
4235 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Added Makefile.defines_int to include the actual definitions
4238 for Makefile.defines.in. Tested the new distribution system,
4239 created distributions and tested installation.
4241 * Added AWAY message printing to the Irssi SILC client. Added
4242 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4244 * Added SCONNECT command to call the SILC's CONNECT command.
4245 Cannot use CONNECT directly since Irssi uses that internally.
4246 Affected file irssi/src/silc/core/silc-servers.c.
4248 Added ACTION local command. It is same as ME command but takes
4249 the channel as mandatory argument.
4251 Rewrote some of the Irssi's help files to suite for SILC
4254 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Added Makefile.defines[.in] that should for now on be included
4257 in all Makefile.am file in the source tree. That file includes
4258 all common compilation definitions for SILC source tree.
4260 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Minor changes to the ./prepare script to change the package
4263 name according the distribution name to the configure.in.
4265 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Created new distribution system. Added file `distributions'
4268 that defines all the distributions that can be created out of
4269 the SILC source tree. The ./prepare script now reads that
4270 file to determine how to prepare the distributions. The
4271 first argument to the ./prepare is the name of the distribution
4272 and second is the version of the distribution. If given
4273 without arguments it creates the default (toolkit) distribution
4274 with the default version (defined in ./prepare).
4276 All Makefile.am files that are subject to the distributions
4277 are now named as Makefile.am.pre. These are ./Makefile.am
4278 and lib/Makefile.am. Others may be changed later.
4280 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Added invite list, ban list, some key management and connection
4283 error message printing to module formats in the Irssi SILC client.
4285 * Added new silc_client_set_away_message to set the away message
4286 that is back to the person who sent private message. The
4287 affected file lib/silcclient/silcapi.h and the
4288 lib/silcclient/client_prvmsg.c.
4290 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Fixed the private message sending in the Irssi SILC client,
4293 added local command KEY to the Irssi SILC client.
4295 Added key management and key agreement message formats to the
4296 irssi/src/fe-common/silc/module-formats.[ch].
4298 Added USERS (alias WHO) printing, server/router operator
4299 indication and LIST command printing to the module formats.
4301 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Fixed channel joining notify handling, cumode notify handling
4304 from Irssi SILC client.
4306 * Added SILC specific module-formats to the Irssi SILC client so
4307 that SILC specific message hilighting, colors etc is possible.
4308 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4310 Added channel mode, channel user mode, actions, notices,
4311 whois and whowas printing to the the module-formats.c.
4313 * Fixed a bug in channel deletion in the server. The channel
4314 is not left to the cache even if the channel founder auth mode
4315 is set when there are no users anymore on the channel. Affected
4316 file silcd/server.c.
4318 * The silc_net_localhost now resolves the entire hostname including
4319 the domain name. Affected file lib/silcutil/silcnet.c.
4321 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4323 * Changed the ask_passphrase client operation to be ascynchronous.
4324 It has now a completion callback and a context that the
4325 application must call after it has got the passphrase from
4326 the user. Affected files lib/silcclient/silcapi.h,
4327 lib/silcclient/protocol.c, lib/silcclient/command.c and
4330 Added SilcAskPassphrase callback that the application calls
4331 to deliver the passphrase to the library.
4333 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4334 The public key verification and especially a certificate
4335 verification is asynchronous procedure.
4337 Added new SILC_SKE_STATUS_PENDING status to indicate the
4338 request is pending and a callback will be called to finalize
4341 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4342 indicate that remote end did not send its public key (or
4343 certificate), even though we require it. Added check for this
4344 condition in the SKE. This was a security bug, now fixed.
4346 Defined new SilcSKEVerifyCbCompletion callback that is called
4347 when the verification process is completed.
4349 The affected files lib/silcske/silcske_status.h and
4350 lib/silcske/silcske.[ch].
4352 * Changed the verify_public_key client operation to be async
4353 as well. Defined SilcVerifyPublicKey callback that is used to
4354 indicate the success of the public key verification process.
4356 Changed the server and client to use the new async client
4359 * Changed the Irssi SILC client's internal scheduler to be called
4360 twice as many times as it used to be. As a result the client
4361 should be a bit faster now. Affected file is
4362 irssi/src/silc/core/silc-core.c.
4364 * Added support to Irssi SILC client of asynchronous public key
4365 verification and passphrase inquiry. Affected file is
4366 irssi/src/silc/core/silc-core.c.
4368 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * Do not say "You have left channel %s" in client library.
4371 Moved it to the application. Affected files are
4372 lib/silcclient/command.c and silc/client_ops.c.
4374 * Fixed silc_client_get_clients. Command context was not
4375 duplicated and was freed memory in the callback. Affected
4376 file lib/silcclient/idlist.c.
4378 * Do not say "you are now talking..." on JOIN command in the
4379 client library. The appliation must handle it.
4381 * Do not say ".. changed topic to" in command reply in the
4382 client libary. The application must handle it.
4384 * Fixed TOPIC command sending in the client library.
4386 * Fixed a memory leak in silc_client_command_free in the file
4387 lib/silcclient/command.c.
4389 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Imported a modified version of Irssi client to the source tree.
4392 The Irssi will be used to create a new client called
4393 Irssi SILC. Imported to irssi/.
4395 Added silc_core_init_finish function to the Irssi. Affected
4396 file irssi/configure.in.
4398 A lot changes in the Makefile.ams around the irssi tree.
4400 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Do not rehash if the new size is same as the old size of the
4403 hash table, in the silc_hash_table_rehash*. The affected file
4404 lib/silcutil/silchashtable.c.
4406 * Replaced hash_table_del_by_context calls from the server
4407 (when channel->user_list and client->channels) to the
4408 hash_table_del as it is sufficient and faster.
4410 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Added silc_hash_table_list, silc_hash_table_get and the
4413 SilcHashTableList structure to provide an alternative way to
4414 traverse the hash table. The affected files are
4415 lib/silcutil/silchashtable.[ch].
4417 * Changed the server's idlist routines to use the hash table
4418 routines to optimize the code.
4420 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Replaced the client entry's `channel' list and channel entry's
4423 `user_list' list to hash tables for optimized lookup. Changed
4424 the code to use the hash table interface around the code.
4425 Affected file lib/silcd/idlist.[ch].
4427 * Added `auto_rehash' boolean argument to the function
4428 silc_hash_table_alloc to indicate whether the hash table should
4429 auto-rehash when it thinks is appropriate time. It will
4430 increase the hash table size if the there is twice as much
4431 entries in the table than the size of the table, and will
4432 decrease the size if there are twice as less entries than
4433 the size of the table.
4435 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4437 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4439 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * silc_idcache_purge_by_context deletes the entry now by context
4442 as it is supposed to do. Affected file lib/silccore/idcache.c.
4444 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4445 client is not anymore valid (WHOWAS givens the info) and not
4446 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4448 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Removed the `data' and `data_len' arguments from the ID Cache
4451 interfaces and added `name' argument. ID Cache does not handle
4452 anymore the binary data only a names associated with given ID.
4454 * When hashing a Client ID with silc_hash_id the entire ID is
4455 not hashed anymore, instead only the hash of the Client ID is
4456 hashed. This way we can access the Client ID from the cache
4457 with Client ID but with the hash of the ID (which is a hash of
4458 the nickname) as well without any difference in performance.
4460 Added also silc_idcache_find_by_id_one_ext to do one on one
4461 searching when we have the actual ID. Added also function
4462 silc_hash_client_id_compare. The affected files are
4463 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4465 * When hashing the name associated with a ID it is always done
4466 in lowercase. This way we can access the cache without worrying
4467 about case-sensitivity, even though, for example nicknames are
4470 * Fixed a bug in server with channel message sending. It put
4471 wrong ID type as destination ID. The affected file
4472 silcd/packet_send.c.
4474 * silc_idcache_del_by_context now deletes from all hash tables
4475 by context. Affected file lib/silccore/idcache.c.
4477 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * Changed the client library to use the new ID Cache interface.
4480 Changes around the source tree.
4482 * Added silc_hash_table_rehash_ext to rehash with specific
4483 hash function. Affected file lib/silcutil/silchashtable.[ch].
4485 * Added silc_hash_string_compare to compare two strings in the
4486 hash table. Affected file lib/silcutil/silcutil.[ch].
4488 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Added new function silc_idcache_del_by_context into the
4491 lib/silccore/idcache.[ch].
4493 * Changed the server's ID list routines to use the new ID Cache
4494 interface. Changes around the source tree.
4496 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Added silc_hash_table_del[_by_context]_ext functions in to the
4499 lib/silcutil/silchashtable.[ch].
4501 Removed silc_hash_table_find_all* routines and added new
4502 silc_hash_table_find_foreach to replace them.
4504 Added silc_hash_table_replace_ext function as extended
4505 replacing function. Separated the simple hash table interface
4506 from the extended hash table interface in the file
4507 lib/silcutil/silchashtable.h.
4509 * Fixed minor bugs and changed it to use some of the new
4510 hash table functions in lib/silccore/idcache.c
4512 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Added new function silc_hash_table_find_all to return all keys
4515 in the hash table by the specified key. As the hash table is
4516 collision resistant it also makes it possible to have several
4517 duplicate keys in the hash table. This function may be used to
4518 find all of the keys from the hash.
4520 Added user_context arguments to the SilcHashFunction,
4521 SilcHashCompare and SilcHashDestructor to deliver user specified
4524 Added new fuctions silc_hash_table_find[_all]_ext to do
4525 extended lookup with specified hash and compare functions and
4526 specified user contexts.
4528 Added new function silc_hash_table_add_ext to add the key
4529 with specified hash function and user context.
4531 Added new function silc_hash_table_foreach to traverse all
4532 entrys in the hash table. Added SilcHashForeach callback
4535 Added new function silc_hash_table_del_by_context to delete
4536 the entry only if the context associated with the key matches.
4538 Affected files are lib/silcutil/silchashtable.[ch].
4540 * Removed silc_hash_[server/client/channel]_id and added just
4541 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4542 silc_hash_id_compare to compare two ID's using as the hash table
4543 comparison function. Added also silc_hash_data to hash
4544 binary data and silc_hash_data_compare to compare it.
4546 * Removed silc_idlist_find_client_by_hash as it is not needed
4547 anymore. Affected file silcd/idlist.[ch].
4549 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4550 to use internally the SilcHashTable. The new ID Cache is a lot
4551 faster than the old one. Some of the ID Cache interface was also
4552 rewritten and obsolete and stupid functions were removed.
4554 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4556 * Added entry_count field to the SilcHashTable to keep the number
4557 of the entries in the table. Implemented the function
4558 silc_hash_table_rehash. Added new function
4559 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4561 Fixed a minor bug in silc_hash_table_free.
4563 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4564 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4565 into the lib/silcutil/silcutil.[ch].
4567 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Implemented a collision resistant hash table into the
4570 lib/silcutil/silchashtable[ch]. See the header and the source
4571 for the SilcHashTable API.
4573 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Merged dotconf version 1.0.2 into lib/dotconf.
4577 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Do not compile anything in lib/silcsim/* if the SIM support
4580 is not enabled. The tree should now compile without problems
4583 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Compiled the SILC under cygwin. Compiled and tested briefly
4586 without problems. More tests needed. The SIMs didn't compile
4589 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4591 * Fixed possible crash in silc_get_username in the
4592 lib/silcutil/silcutil.c.
4594 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Fixed a va_arg in silc/client_ops.c.
4598 * Oops, RC5 routines were named AES and caused some problems
4599 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4601 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4603 * Added new SilcIDIP structure into the lib/silccore/id.h and
4604 replaced the old `ip' fields from all SILC ID's to that type.
4605 This is a step towards IPv6 support.
4607 The silc_id_get_len takes now the ID as an extra argument.
4608 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4609 both IPv4 and IPv6 based ID's.
4611 The affected files are lib/silccore/id.[ch] and other files
4612 around the tree using these routines.
4614 * Removed the ID length arguments in server from various
4615 silc_server_send_notify_* routines -> they are not needed
4618 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Fixed memory leak in silc_encode_pem_file in the file
4621 lib/silcutil/silcutil.c.
4623 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * Check minor version as well in the SKE. Affected files are
4626 silcd/protocol.c and lib/silcclient/protocol.c.
4628 * Added --identifier option to the server so that an identifier
4629 can be when creating the public key for the server. Affected
4630 file is silcd/silcd.c.
4632 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4633 lib/silccrypt/silcpkcs.c.
4635 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Register default ciphers and stuff when using -C option with
4638 the server. Affected file sildc/silcd.c.
4640 * Put back the servers public key filename format, it is better
4641 than the new one. For now, the client keys are saved with the
4642 new filename format. The affected file silc/client_ops.c.
4644 * Implemented the Cipher API for the rest of the ciphers that
4645 did not implement it or implemented it the wrong way.
4647 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Register default ciphers and stuff when using the -S option
4650 in the client. Affected file silc/silc.c. Same also when
4651 creating new key pair with -C option.
4653 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Fixed the silc_verify_public_key client operation function to
4656 save the public keys differently. The fingerprint is now
4657 used as filename and not the hostname. This way also the
4658 client keys are saved uniquely and not with hostnames. The
4659 affected file is silc/client_ops.c.
4661 * Trimmed the silc_hash_fingerprint function to remove extra
4662 whitespaces from the end of the fingerprint. The affected
4663 file is lib/silccrypt/silchash.c.
4667 * Added silc_cipher_register_default function to register all
4668 default ciphers. It can be used when configuration files
4669 does not exist and the application does not want any specific
4670 ciphers in any specific order.
4672 The SilcDList is now used as silc_cipher_list dynamically
4673 allocated cipher list. Removed the static list all together
4674 and now all ciphers must be allocated to the dynamic list.
4675 The silc_cipher_alloc routine was changed to check only the
4678 All silc_cipher_* routines that used to return int returns
4681 The affected files lib/silccrypt/silccrypt.[ch].
4683 * The same thing was done to silc_hash_* as for silc_cipher_*
4684 routines. Affected files lib/silccrypt/silchash.[ch].
4686 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4687 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4688 Added also silc_pkcs_[un]register[_default] functions.
4689 Removed the data_context from the PKCS API.
4691 * Added silc_hmac_register_default function to register default
4692 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4693 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4694 to unregister all hmacs at once.
4696 * Register the default ciphers, hash functions, PKCSs and HMACs
4697 if client's configuration file does not exist. The affected
4700 * The client did not load the hash functions from the SIM
4701 modules at all. Added support for this. Affected file is
4702 silc/clientconfig.c.
4704 * When decoding public key with silc_pkcs_public_key_decode, check
4705 the supported algorithm only if PKCS are registered. Affected
4706 file lib/silccrypt/silcpkcs.c. The same was done with the
4707 silc_pkcs_private_key_decode.
4709 * Fixed the SILC List routines to keep the list always in order.
4710 It used to change the list's order when traversing the list but
4711 not it preserves the order. Affected file lib/trq/silclist.h.
4713 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Added the client library to use the SilcSocketConnection's
4716 reference counter (by silc_socket_dup) to prevent the bug that
4717 the socket object may be freed underneath async operation.
4719 * The name resolv library checking fixes in the configure.in.pre.
4722 * Created new version of the protocol drafts for future
4723 development. The -03 drafts are the ones that will be changed
4724 in the trunk now and the -02 will remain as they are.
4726 * Send list of CUMODE notifys to the router when announcing
4727 the channel users to the router. Affected file silcd/server.c.
4728 If the router receiving channel founder CUMODE for a channel
4729 that already has channel founder it will send CUMODE notify
4730 to the sender to remove the channel founder rights from the
4731 announced client. Affected file silcd/packet_receive.c.
4733 * The CUMODE notify may now use Server ID as well as the entity
4734 who changes the mode. Updated protocool specs.
4736 * Updated INSTALL and README files.
4738 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * New web pages in the http://silc.pspt.fi. The pages was
4745 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Implemented the [DenyConnectin] config section in the server.
4748 Added silc_server_config_denied_conn to check whether incoming
4749 connection is denied. Affected file silcd/serverconfig.[ch].
4751 * Do not check the ports when checking the incoming configuration
4752 data if the port is 0, meaning any. Affected file is
4753 silcd/serverconfig.c.
4755 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Fixed buffer overflow in silc_string_compare in the file
4758 lib/silcutil/silcutil.c.
4760 * Fixed double free in silc_server_command_leave in the file
4763 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Fixed the version checking in the server. Affected file is
4768 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Fixed the configuration data fetching when accepting new
4771 connections in the server. Affected file silcd/server.c.
4773 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Added `sender_entry' argument to the function
4776 silc_server_packet_relay_to_channel so that we can check
4777 whether some destination actually belongs to the same route
4778 the sender belongs (ie, we must not resend the packet to the
4779 sender). Affected file silcd/packet_send.[ch].
4781 * Added `servername' field to the SilcClientEntry in the server
4782 to hold the name of the server where client is from. Affected
4783 file is silcd/idlist.h.
4785 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * Moved the channel message encrypting in the router betwen
4788 router connections from silc_server_channel_message to the
4789 silc_server_packet_relay_to_channel since we want to check
4790 whether we have anybody channel before encrypting anything.
4791 Affected files silcd/packet_[receive/send].c.
4793 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Fixed the [AdminConnection] server config section to support
4796 multiple entries. Affected file silcd/serverconfig.c.
4798 * Added support into the server to check the validity of the
4799 incoming connection before executing any KE or authentication
4802 * The connection configuration is now saved to the KE and
4803 connection auth protocol contexts and not fetched anymore in
4804 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4806 * The local hosts listenning address and port is also resolved
4807 now when starting the server. We want to have the socket object
4808 to include the real address and port for the listener. Added
4809 new function silc_net_check_local_by_sock into the files
4810 lib/silcutil/silcnet.[ch].
4812 * Fixed a broadcast bug in server -> do not broadcast if we
4815 * Fixed a routing bug. Do not route broadcast packets ever.
4816 Broadcast packets must be processed always and not routed since
4817 they may be destined to some other host than yourself and thus
4818 would get routed without no good reason. Affected file is
4821 * Added function silc_server_config_is_primary_route to check
4822 whether primary router connection has been configured (a router
4823 configuration that we are initiating). If there is not, we
4824 will assume that there is only two routers in the SILC network
4825 and we will use the incoming router connection as our primary
4826 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4828 * Changed the order of the broadcasting. Broadcast _after_ the
4829 packet has been processed not before. Affected file is
4832 * Fixed a [ClientConnection] parsing bug. The port was never
4833 parsed correctly thus resulting to port 0. Affected file
4834 silcd/serverconfig.c.
4836 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4837 argument and did not set the broadcast packet flag. Affected
4838 file silcd/packet_send.c. Fixed same bug in the function
4839 silc_server_send_notify as well.
4841 * If we receive NEW_ID packet for our own ID in the server, ignore
4844 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Removed the nickname from the Private Message Payload.
4849 Updated the code and the protocol specs.
4851 * Updated protocol specs for submitting to the IETF.
4853 * Tweaked the Random Number Generator a bit. Affected file
4854 lib/silccrypt/silcrng.c. Exported a new function
4855 silc_rng_[global]_add_noise which can be used to add more
4858 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4860 * Do not parse packets with different timeout when protocol
4861 is active -> may cause problem with rekey. Affected file
4864 * When server receives signoff notify it must not create
4865 new channel key if the client is on any channels since the
4866 sender of the signoff notify will create it.
4868 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Added printing of error messages during SKE protocol from the
4871 failure packet sent by server during SKE. Affected file
4874 * Removed the client's failure_callback handling with timeout
4875 and handle it immediately when received.
4877 * The SKE library returned wrong type in SUCCESS and FAILURE
4878 packets. They must be 32 bit MSB not 16 bit MSB.
4880 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Ok, rewrote the logic of the re-key and now it seems to work.
4883 I tested it on high traffic with frequent re-keys without
4884 problems. Added hmac_receive (and renamed hmac to hmac_send)
4885 in SilcClientConnection in lib/silcclient/client.h and
4886 in SilcIDListData in silcd/idlist.h. Also, removed the
4887 SilcPacketParserContext's cipher and hmac fields as they are
4888 not needed anymore and actually caused some problems when
4889 the ciphers and hmac's changed underneath the packet parser.
4891 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * If re-key protocol is active then process the incoming packets
4894 synchronously since we must assure that icoming packets encrypted
4895 with the old key is processed before the new keys is set to
4896 use. This is true other packets than for REKEY packets.
4897 Affected file silcd/server.c. The same was done to client library
4898 as well, affected file lib/silcclient/client.c.
4900 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Fixed bug in client and server to accept the force send if
4903 the packet is send from silc_[server/client]_packet_process
4904 function. Otherwise the packets are never delivered, oops.
4906 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4908 * Disable force sending of packets when REKEY protocol is active.
4909 We must assure that no packet is sent directly when rekey is
4910 performed. All packets must be sent through packet queue.
4911 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4912 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4913 function is silc_[server/client]_packet_send_real to check
4916 * Replaced the SIM paths from example config files to
4917 /usr/local/modules. Also, make install creates now
4918 /usr/local/silc/logs directory to hold all the SILC server
4921 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Made the configure.in.pre work on Solaris. Patch by salo.
4925 * Made all ciphers compatible with non-x86 machines. Defined
4926 CBC mode macros into lib/silccrypt/ciphers_def.h.
4928 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4930 * Fixed the make install.
4932 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * When MAC computation fails the silc_packet_decrypt returned 0
4935 even though it was supposed to return -1. Fixed this. The
4936 affected file is lib/silccore/silcpacket.c.
4938 * Do not replace the config files in /etc/silc (in make install)
4939 if they already exist. Affected file ./Makefile.am.
4941 * Do not send re-key packets immediately but through packet queue.
4942 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4944 * Changed silc_net_check_host_by_sock to return FALSE if the
4945 IP/DNS could not be resolved. Though, it returns the IP address
4946 now even if it could not resolve it (but returns also FALSE).
4947 Affected file lib/silcutil/silcnet.[ch].
4949 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4951 * Added silc_pkcs_decode_identifier to decode the public key's
4952 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4953 Added also silc_pkcs_free_identifier. Added also new context
4954 SilcPublicKeyIdentifier.
4956 * Added -S option to the silc client. It is used to dump the
4957 contents of the specified public key file.
4959 * Changed the PKCS api to return the public key length when
4960 setting the public key.
4962 * Fixed a fatal bug in the public and private key file loading.
4963 Affected file lib/silccrypt/silcpkcs.c.
4965 * Execute the packet parsing for client with zero (0) timeout
4966 if the protocol is active. Affected file silcd/server.c.
4968 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Made the key generation options to the silcd program. Added
4971 -C option, equivalent to client's option.
4973 * Added new [ServerKeys] config section to the server. It
4974 configures the server's public and private key.
4976 * Defined generic Public Key Payload into the protocol
4977 specification to send specific type of public keys and
4980 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4981 public key or certificate.
4983 * Implemented the GETKEY command to the server and to the
4984 client library and on user interface.
4986 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Made preliminary `make install' work.
4990 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Added SilcServerRekey context into silcd/idlist.h.
4994 * Added the PFS support as defined in the specification to the
4995 SKE protocol. Affected files lib/silcske/*.c.
4997 * Added `ske_group' field to the SilcServerRekey context to hold
4998 the number of the SKE group that is used with PFS in re-key.
4999 Affected file silcd/idlist.h.
5001 * Added PFS re-key support to the server. Affected file is
5004 * Added silc_protocol_cancel to cancel execution of the next
5005 state of the protocol. Affected file is
5006 lib/silccore/silcprotocol.[ch].
5008 * Added the re-key support with and without PFS to the client
5009 library. Re-key is performed once in an hour, by default.
5011 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5012 Added silc_client_rekey_callback and silc_client_rekey_final.
5013 Affected files are lib/silcclient/protocol.[ch] and
5014 lib/silcclient/client.[ch].
5016 * Removed the `hmac_key' and `hmac_key_len' fields from the
5017 SilcClientConnection structure; not needed. Affected file is
5018 lib/silcclient/client.h.
5022 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * Do not ask whether user wants to use the negotiated private key
5025 for private messages, just use it. Affected file is
5026 silc/local_command.c.
5028 * Added `send_enc_key' and `enc_key_len' fields to the
5029 SilcIDListData structure since they are needed in the re-key
5030 phase. Affected file is silcd/idlist.[ch].
5032 * Implemented the simple re-key protocol into the server.
5033 Affected files silcd/server.c and silcd/protocol.[ch]. The
5034 re-key will be performed once in an hour, by default.
5036 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5037 Added silc_server_rekey, silc_server_rekey_callback and
5038 silc_server_rekey_final.
5040 * Removed Tunneled flag from the protocol. Updated the code
5041 and the specifications.
5043 * Adde `pfs' field to the SilcIDListData to indicate whether
5044 the PFS is to be performed in the re-key. Affected file is
5047 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5050 int64 of at least the xintXX size. If void * is less that 4
5051 bytes uint32 * will be used. Defined bool as boolean.
5053 * Changed _ALL_ unsigned long and unsigned int to uint32,
5054 unsgined short to uint16 in the source tree.
5056 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5057 not handle clients that has entry->data.registered == FALSE.
5058 They are not in the network anymore. Affected file is
5061 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Implemented the sending of the SERVER_SIGNOFF notify in the
5064 server. Affected file is silcd/server.c.
5066 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5067 Added also silc_notify_payload_encode_args into the
5068 lib/silccore/silcnotify.[ch].
5070 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5071 Affected file silcd/packet_receive.c.
5073 * Implemented the SERVER_SIGNOFF notify handling in the client
5074 library. Affected file lib/silcclient/client_notify.c. Also,
5075 implemnted the printing of the SERVER_SIGNOFF info to the
5076 application. Affected file silc/client_ops.c.
5078 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5079 if the deleting was successful. Affected file silcd/idlist.[ch].
5081 * Added support for public key authentication in the connection
5082 authentication protocol in the client library. Affected file
5083 lib/silcclient/protocol.c.
5085 * Changed the server's silc_idlist_get_clients_by_* interface
5086 to support already allocated array so that new entries may be
5087 added to pre-allocated array. Affected file silcd/idlist.[ch].
5088 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5089 and command replies.
5091 * All command reply functions in the server now calls the
5092 pending command callback even if error occured. This way the
5093 error will be delivered to the client as well. Affected files
5094 silcd/command.c and silcd/command_reply.c.
5096 * Fixed INFO command to return local server's info if no server
5097 was provided. Affected file lib/silcclient/command.c.
5099 * Removed RESTART command for good. Updated the code and the
5102 * Rewrote parts of the task system. It is a bit simpler now.
5103 Removed unsued task priorities. The affected files are
5104 lib/silcutil/silctask.[ch].
5106 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Moved the USERS printing from the library to the application.
5109 Affected files lib/silcclient/command.c and silc/client_ops.c.
5111 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Added channel key re-key support. The re-key is perfomed
5116 only by the router and is done once in an hour. Added `rekey'
5117 field to the SilcChannelEntry in the server. Affected files
5118 silcd/server.c and silcd/idlist.h.
5120 * Added silc_task_unregister_by_context into the file
5121 lib/silcutil/silctask.[ch].
5123 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5125 * Added SILC_UMODE_GONE mode to indicate when the client is not
5126 present in the SILC network. Added also support to the local
5127 command AWAY that will set this mode. Added support of showing
5128 "xxx is gone" in WHOIS command. The USERS command shows the
5129 gone status as well.
5131 * Fixed setting server and router operator privileges in the
5132 server's UMODE command. Affected file silcd/command.c.
5134 * Merged the SKE KE1 and KE2 payloads into one payload. The
5135 new KE payload is equivalent to the old KE2 payload.
5137 Cleaned up the SKE Start Payload parsing. It now uses the
5138 simple buffer unformatting to do the parsing. A lot faster
5141 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5142 to the SKE that is used to indicate whether both of the SKE
5143 parties should perform authentication. By default only the
5144 responder performs authentication. By setting this flag also
5145 the initiator must do authentication. By default it is unset
5146 since in normal SKE case, client to server connection, only
5147 the responder should do authentication. When doing SKE between
5148 two clients both should perform authentication. Updated the
5149 code and the protocol specs.
5151 * A little fix to IDENTIFY command in the server. Search the
5152 client first by hash not nickname. Affected file is
5155 * Fixed the silc_client_close_connection to support closing
5156 the client to client connections wihtout deleting too much
5157 data. Affected file lib/silcclient/client.c.
5159 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5160 are received if protocol used to be active but is not anymore
5161 the application would crash due to NULL pointer dereference.
5162 Affected files silcd/server.c and lib/silcclient/client.c.
5164 * Added `hash' field to the SilcClientConnection to include
5165 the hash function negotiated in the SKE protocol.
5167 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5168 to set the channel founder authentication data. A client can
5169 claim the founder rights later by providing the authentication
5170 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5171 This way the channel founder can regain the channel founder
5172 privileges even it is left the channel. This works only on
5173 local server and the client must be connected to the same
5174 server to be able to regain the founder rights. Updated the
5175 protocol specs accordingly.
5177 Added support to the CMODE command in the client to set the
5178 founder auth data. Read the README to see how to set it.
5180 Added support to the CUMODE command to claim the founder
5181 rights. Read the README to see how to do it.
5183 Added support for the founder authentication to the Channel
5184 Entry in the server. Affected file silcd/idlist.h.
5186 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5187 server's CMODE command. Affected file silcd/command.c.
5189 * Added the following new functions into lib/silccore/silcauth.[ch]:
5190 silc_auth_get_method and silc_auth_get_data.
5192 * The server now saves the remote hosts public key to the
5193 SilcIDListData pointer. Affected file silcd/protocol.c.
5195 * The normal server now does not remove the channel entry from
5196 the cache if the founder authentication data is set. It used
5197 to remove it if the founder was the last one on the channel on
5198 the server and left the channel. The auth data is saved and
5199 if the channel is re-joined later the old entry is used with
5200 the old auth data. Affected files silcd/command_reply.c and
5203 * Removed the `pkcs' field from the SilcIDListData structure
5204 in the server; it is not used. Affected file silcd/idlist.h.
5206 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Fixed packet processing on slow links. Partial packets were
5209 never re-processed because the incoming data buffer was cleared
5210 by the application. Application must not directly clear the
5211 sock->inbuf, the packet processing routines handle it. Fixed
5212 this in client library and in server.
5214 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Fixed the WHOIS and IDENTIFY send reply function to really
5217 check whether to send list or just one entry. Affected file
5220 * Cleaned up the LEAVE command's channel key distribution. The
5221 affected file silcd/command.c.
5223 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5224 can enforce the channel mode as well. In that case the ID
5225 includes the ID of the server. The code now enforces the
5226 mode change if the router have different mode than the server.
5228 * The notify client operation with CMODE_CHANGE notify can now
5229 return NULL client_entry pointer if the CMODE was not changed
5230 by client. Application must check for this.
5232 * Added <Server ID> argument to INFO command to support server
5233 info fetching by Server ID.
5235 * Added silc_server_announce_get_channel_users to get assembled
5236 packets of channel users of the specified channel. Affected
5237 file silcd/server.[ch].
5239 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5240 was freed underneath the ID Cache.
5242 * Re-announce clients when the server received CHANNEL_CHANGE
5243 notify from the router. Affected file silcd/packet_send.c.
5245 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5248 crashed since it did not handle the fact that there is no cipher
5249 called "3" and didn't check the error condition. Now fixed.
5251 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5252 flag. It can be used to send message requests.
5254 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Implemented the RESTART command in the client.
5258 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5259 notice type messages. Added notice printing to the user
5262 * The channel keys are not re-generated if the channel's mode
5263 is PRIVKEY, ie private key on the channel exists. Affected
5264 files silcd/server.c and silcd/command.c.
5266 * Fixed a little bug in channel message delivery when channel
5267 private keys are set in the server. Affected file is
5268 silcd/packet_send.c.
5270 * Changed the setting on channel->on_channel = TRUE from the
5271 silc_client_save_channel_key to the JOIN command reply. The
5272 key payload is not received if the private channel key is set.
5273 Affected file lib/silcclient/command_reply.c and the
5274 lib/silcclient/client_channel.c.
5276 * When the CMODE_CHANGE notify is sent and the channel private
5277 key mode is removed the channel key must be re-generated in
5278 other cells as well. Added this support for the router in the
5279 silcd/packet_receive.c.
5281 * Added new local command NOTICE to send notice message on
5282 channel. Affected file silc/local_command.[ch].
5284 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Added new local command ME to the client. It is used to send
5287 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5288 some action. Affected file silc/local_command.[ch].
5290 * Changed channel_message and private_message client operations
5291 to deliver the message flags to the application. Added also
5292 the `flags' arguments to the silc_client_send_channel_message
5293 and silc_client_send_private_message functions. Affected file
5296 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Redefined the Private Message Payload to support private message
5299 keys and to support the new private message flags. Updated
5300 the protocol specs. Flags makes it possible to have for example
5301 CTCP style messages.
5303 * Added new type SilcPrivateMessagePayload and defined an API
5304 for it in the lib/silcclient/silcprivate.[ch].
5306 * Tested private message private keys successfully. Tested the
5307 private message key set, unset and list commands with the new
5310 * Redefined the Channel Message Payload to include the channel
5311 message flags (equal with private message flags) to support
5312 for example CTCP style messages.
5314 * Defined some of the message (for channel and private message)
5315 flags. Updated the protocol specs and added the flags to the
5316 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5318 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Added SilcKeyAgreementStatus type to the key agreement routines
5321 to indicate the current status and error if one occured.
5322 The status types are defined in the lib/silcclient/silcapi.h.
5324 * Added new local command KEY that is used to set and unset private
5325 keys for channels, set and unset private keys for private messages
5326 with remote clients and to send key agreement requests and
5327 negotiate the key agreement protocol with remote client. The
5328 key agreement is supported only to negotiate private message keys,
5329 it currently cannot be used to negotiate private keys for channels,
5330 as it is not convenient for that purpose.
5332 * Fixed a minor pending callback setting bug in the function
5333 silc_client_get_client_by_id_resolve, now the function works.
5334 Affected file lib/silcclient/idlist.c.
5336 * Added function silc_net_get_local_port to get local bound
5337 port by socket. Added to lib/silcutil/silcnet.[ch].
5339 * Added `sockets' and `sockets_count' fields to the SilcClient
5340 object. They hold the sockets of the listenning sockets in
5341 the client. Listenning sockets may be for example the key
5342 agreement server. Affected file lib/silcclient/client.[ch].
5343 Added functions the silc_client_add_socket and the
5344 silc_client_del_socket. They are exported to the application
5347 * Added ~./silc/clientkeys to support other client's public keys.
5349 * Renamed verify_server_key client operation to verify_public_key
5350 and added one argument to indicate the type of the connection
5351 (server, client etc.).
5353 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Added silc_server_connection_auth_request to handle the
5356 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5357 silcd/packet_receive.[ch].
5359 * Added silc_server_send_connection_auth_request into the
5360 silcd/packet_send.c to send the connection auth request packet.
5362 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5365 * Fixed the public key authentication in responder side in the
5366 server. The `auth_data' pointer includes the SilcPublicKey
5367 not the path to the public key. Affected file silcd/protocol.c.
5369 * Implemented the public key authentication in the initiator side
5370 in the server. Affected file silcd/protocol.c.
5372 * Removed the [RedirectClient] config section from the server
5373 configuration. Is not needed and I don't want to implement it.
5375 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Cleaned up the CMODE command in the server. It now works
5378 correctly and supports all the modes defined in the protocol.
5379 Affected file is silcd/command.c.
5381 * Added `hmac_name' field to the SilcChannelEntry in the server
5382 to hold the default HMAC of the channel. It can be set when
5383 creating the channel (with JOIN command). Affected files
5386 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5387 type to indicate the change of the current cipher and hmac
5388 on the channel. Client can safely ignore the <cipher> argument
5389 (if it chooses to do so) since the CHANNEL_KEY packet will
5390 force the channel key change anyway. The <hmac> argument is
5391 important since the client is responsible of setting the new
5392 HMAC and the hmac key into use.
5394 * Fixed the CMODE command in the client library as well.
5396 * Tested CMODE command in router environment successfully.
5398 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Show the version of the remote client (or server) when connecting
5401 to the server. It is logged to the log file. Affected file
5402 is silcd/protocol.c.
5404 * Fixed the KILLED notify handling in the client library. The
5405 client must be removed from all channels when receiving the
5408 Also, do not remove the client entry when giving the KILL
5409 command but when the KILLED notify is received.
5411 * Removed silc_idlist_find_client_by_nickname from the server.
5412 Not needed anymore. Affected files silcd/idlist.[ch].
5414 * Implemented the CHANNEL_CHANGE notify type handling to the
5415 server. Affected file silcd/server.c.
5419 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5421 * Added silc_server_send_notify_invite to send the INVITE
5422 notify between routers.
5424 * Implemented the INVITE command correctly to the server.
5426 * Implemented the INVITE notify type handling in the server.
5428 * Implemented the INVITE command to the client library and on the
5431 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Added function silc_server_get_client_resolve to find the
5434 client entry by ID from all ID lists and then resolve it
5435 (using WHOIS) if it cannot be found. Affected file is
5438 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Implemented the BAN command to the client library.
5442 * The JOIN command in the server now checks the invite list
5445 * Changed the silc_command_reply_payload_encode_va and the
5446 silc_command_payload_encode_va to support that if argument is
5447 NULL it ignores and checks the next argument. Affected file
5448 lib/silccore/silccommand.c.
5450 * Added silc_server_send_notify_ban to send the BAN notify
5451 type between routers.
5453 * Chaned the silc_notify_payload_encode to support that if
5454 argument is NULL it ignores and checks the next argument.
5455 Affected file lib/silccore/silcnotify.c.
5457 * Tested ban lists in router environment successfully.
5459 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Implemented BAN command to the server, in silcd/command.[ch].
5463 * Removed the BAN and INVITE_LIST modes from the CMODE command
5466 * Added function silc_string_match to regex match two strings.
5467 Affected files lib/silcutil/silcutil.[ch].
5469 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5471 * Redefined parts of the SilcChannelEntry in the server to support
5472 the new ban and invite lists.
5474 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Redefined the INVITE command. The same command can be used to
5477 invite individuals to the channel but also to manage the invite
5478 list of the channel (to add to and remove from the invite list).
5479 Updated the protocol specs.
5481 * Added new command SILC_COMMAND_BAN that can be used to manage
5482 the ban list of the channel. Updated the protocol specs.
5484 * Removed the channel modes: the SILC_CMODE_BAN and the
5485 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5486 in the CMODE command. The equivalent features are now available
5487 using INVITE and BAN commands. Updated the protocol specs.
5489 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5490 in the network about change in the current ban list. The notify
5491 type is not used by the client.
5493 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5494 support the invite lists.
5496 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Added new function silc_string_regexify that converts string
5499 including wildcard characters into regex string that can
5500 be used by the GNU regex library. Added into the file
5501 lib/silcutil/silcutil.[ch].
5503 Added silc_string_regex_combine to combine to regex strings
5504 into one so that they can be used as one regex string by
5505 the GNU regex library. Added into the file
5506 lib/silcutil/silcutil.[ch].
5508 Added silc_string_regex_match to match two strings. It returns
5509 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5511 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Imported GNU regex to the soruce tree into lib/contrib.
5514 Fixed some compiler warning from the regex.c.
5516 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Fixed MOTD command in the server to work in router environment.
5520 * Fixed the MOTD command in the client library to support
5521 the server argument in the command.
5523 * Added `nickname_len' argument to the silc_idlist_add_client
5524 in the server, as the `nickname' argument may be binary data
5527 * Added silc_idlist_get_channels to return all channels from
5530 * Implemented LIST command to the server. Affected file is
5533 * Implemented the LIST command to the client library and on the
5536 * Added [<user count>] argument to the LIST command reply.
5537 With private channels the user count is not shown.
5539 * Updated TODO and README.
5541 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * The client entry's data.registered must be TRUE even with
5544 global client entry on global client list. The data.registered
5545 is used to check whether the client is anymore in the network,
5546 for example with WHOWAS command so it must be valid.
5548 * Fixed the WHOWAS command in the server. It now actually works
5549 in router environment. Added function into silcd/command_reply.c
5550 silc_server_command_reply_whowas_save.
5552 * Added silc_idlist_purge function to the silcd/idlist.c
5553 to periodically purge the ID Cache.
5555 * Fixed INFO command in the server. It works now in router
5556 environment. Added <server name> argument to the INFO command
5557 reply. Updated the protocol specs.
5559 * Fixed minor bug in silc_idcache_purge to not purge if the
5560 expire value is zero.
5562 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5563 they were buggy because of the WHOWAS information.
5565 * Fixed local command MSG to handle the async resolving of
5566 the remote client properly. It used to fail the first MSG.
5567 Affected file silc/local_command.c.
5569 * Added `data_len' field to SilcIDCache context.
5571 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Update TODO. Todo in commands in the server.
5575 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5577 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5578 used by routers as broadcast packet to inform other routers
5579 about the changed user mode.
5581 Implemented the notify handling in the server. Affected file is
5582 silcd/packet_receive.c. Added the function
5583 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5585 * Added new generic Channel Payload and deprecated the New Channel
5586 Payload. The New Channel Payload is now the generic Channel
5589 * Added new argument `mode' to the silc_server_send_new_channel
5590 as it is required in the Channel Payload now.
5592 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5593 and created a new and real SilChannelPayload to represent the
5594 new generic Channel Payload. Implemented the encode/decode
5595 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5597 * Added silc_server_get_client_channel_list to return the list
5598 of channels the client has joined for WHOIS command reply.
5599 Affected file silcd/server.[ch].
5601 * Implemented the channel list sending in the WHOIS command reply
5602 in server and in the client.
5604 Implemented the channel list displaying on the user interface
5605 as well. Affected file silc/client_ops.c.
5607 * Added silc_channel_payload_parse_list to parse list of Channel
5608 Payloads. It returns SilcDList list of SilcChannelPayloads.
5609 Client for example can use this function to parse the list of
5610 channels it receives in the WHOIS command reply. The caller
5611 must free the list by calling silc_channel_payload_list_free.
5612 Affected files lib/silccore/silcchannel.[ch].
5614 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Added one new argument <user mode> to the WHOIS command reply
5617 to return the mode of the user in SILC. Updated the protocol
5620 Implemented it to the server and client.
5622 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Fixed the mode printing on the user interface on joining.
5625 Affected file silc/client_ops.c.
5627 * Implemented the UMODE command and user modes in general to the
5628 client library and to the user interface.
5630 * Implemented the UMODE command to the server.
5632 * The server now sends UNKNOWN_COMMAND error status if client sends
5633 unknown command. Affected file silcd/command.c.
5635 * All server commands now handle the command identifier the right
5636 way when sending the command reply to the client. The client can
5637 use to identify the command replies with the identifier.
5639 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Added silc_server_get_client_route to resolve the route to
5642 the client indicated by the client ID. Affected file is
5645 * Added silc_server_relay_packet as general function to relay
5646 packet to arbitrary destination. This deprecates functions
5647 like _send_private_message_key, _relay_notify etc. Affected
5648 file is silcd/packet_send.[ch].
5650 Removed silc_server_send_key_agreement,
5651 silc_server_send_private_message_key and
5652 silc_server_packet_relay_notify functions from the file
5653 silcd/packet_send.[ch].
5657 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5658 server. Affected file silcd/packet_receive.[ch].
5660 * Implemented the KILL command to the client. Implemented the
5661 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5662 Affected files lib/silcclient/command[_reply].c and
5663 lib/silcclient/client_notify.c. Implemented the KILL notify
5664 printing in the user inteface.
5666 * Fixed a lot silc_parse_nick memory leaks from the client
5667 library in the file lib/silcclient/command.c.
5669 * Changed the silc_server_send_notify_on_channels's `sender'
5670 argument from SilcSocketConnection to SilcClientEntry to
5671 check the sender as entry and not as connection object and not
5672 to send to the client provided as argument. The affected file
5673 is silcd/packet_send.[ch].
5675 * The notify packets that are destined directly to the client used
5676 to not to be processed by the server. Now changed that and the
5677 server processes all notify packets. After relaying the packet
5678 to the client the notify packet is processed in the server.
5680 * The silc_server_free_client_data now checks whether there is
5681 pending outgoing traffic for the client and purges the data to
5682 the network before removing the client entry.
5684 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5687 an client is killed from the SILC Network. Updated the protocol
5690 Added new function silc_server_send_notify_killed to the
5691 silcd/packet_send.[ch].
5693 * Added function silc_server_packet_relay_notify to relay notify
5694 packets that are destined directly to a client. In this case
5695 the server does not process the notify packets but merely relays
5696 it to the client. Affected file silcd/packet_send.[ch].
5698 Added also silc_server_packet_process_relay_notify to check
5699 whereto relay the notify. Affected file is
5700 silcd/packet_receive.[ch].
5702 * Implemented the KILL command to the server.
5706 * Added the backup schema desgined last fall to the protocol
5707 specs for everyone to see. The specification is in the
5708 *-spec-xx.txt draft and the packet type definitions for the
5709 backup routers is in *-pp-xx.txt draft. Thusly, added also
5710 new packet type SILC_PACKET_CELL_ROUTERS.
5712 * A big security problem in the implementation discovered. The
5713 signoff of an client did not cause new channel key generation
5714 which it of course should've done. The channel keys must be
5715 always re-generated when client leaves (or signoffs) the channel.
5716 The silc_server_remove_from_channels funtion now handles
5717 the channel key re-generation.
5719 * Added `sender' argument to the silc_server_send_notify_on_channels
5720 to not to send the client provided as argument. Affected file
5721 silcd/packet_send.[ch].
5723 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5725 * Implemented OPER and SILCOPER commands into the server and
5728 * Added silc_auth_verify and silc_auth_verify_data to verify
5729 the authentication directly from the authentication payload.
5730 It supports verifying both passphrase and public key based
5731 authentication. Affected file lib/silccore/silcauth.[ch].
5733 * Added `hash' field to the SilcIDListData structure. It is the
5734 hash negotiated in the SKE protocol. Affected file is
5737 * Slight redesigning of the SilcAuthPayload handling routines.
5738 Do not send SilcPKCS but SilcPublicKey as argument.
5740 * Implemented the public key authentication support to the
5741 serverconfig. The public key is loaded from the provided path
5742 and saved as authentication data to void * pointer. Thus,
5743 changed the unsigned char *auth_data to void *auth_data;
5745 * Fixed SHUTDOWN command to send the reply before the server
5746 is shutdown. :) Affected file silcd/command.c.
5748 * Fixed fatal bug in CONNECT command. The hostname was invalid
5749 memory and server crashed. Affected file silcd/command.c.
5751 * Fixed fatal bug in CLOSE command. The server_entry became
5752 invalid but was referenced later in the command. Affected file
5755 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Fixed fatal bug in failure packet handling. Server ignored
5758 the failure and thus crashed when it came.
5762 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5764 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5765 that the command may be executed only once in (about) 2 seconds.
5766 The old SILC_CF_LAG flag is same but allows command bursts up
5767 to five before limiting.
5769 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5770 server code. Various commands now includes the CF_LAG_STRICT
5771 flag to disallow any kind of miss-use of the command.
5773 * Fixed the silc_buffer_unformat to not to allocate any data
5774 if the length of the data is zero. It used to allocate the
5775 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5777 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * Changed the format of AdminConnection configuration section
5780 in the server. Added username of the admin to the format.
5781 Affected files silcd/serverconfig.[ch].
5783 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5784 to return admin configuration data by host, username and/or
5787 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5789 * Implemented WHOWAS command to the server. Added the functions:
5791 silc_server_command_whowas_parse,
5792 silc_server_command_whowas_send_reply,
5793 silc_server_command_whowas_from_client and
5794 silc_server_command_whowas_from_server
5796 * Added <Client ID> argument to the WHOWAS command reply. Updated
5797 the protocol specs accordingly.
5799 * Implemented WHOWAS command and command_reply to the client
5802 Implemented the WHOWAS printing on the user interface.
5804 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Added new argument to the WHOWAS command reply, the real name.
5807 It is an optional argument. Updated the protocol specs.
5809 * Added SilcIDCacheDestructor callback that is registered when
5810 the SilcIDCache is allocated. The callback is called when
5811 an cache entry in the ID Cache expires, or is purged from the
5812 cache. Added into lib/silccore/idcache.[ch].
5814 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5815 to destruct the client entries when the cache entry expires.
5816 Other ID Cache's in server and in the client library ignores
5819 * If the ID Cache entry's `expire' field is zero then the entry
5820 never expires. Added boolean `expire' argument to the
5821 silc_idcache_add function in the lib/silccore/idcache.[ch].
5822 If it is TRUE the default expiry value is used.
5824 * Added silc_server_free_client_data_timeout that is registered
5825 when client disconnects. By default for 5 minutes we preserve
5826 the client entry for history - for WHOWAS command.
5828 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5830 * Added support to the server to enforce that commands are not
5831 executed more than once in 2 seconds. If server receives
5832 commands from client more frequently, timeout is registered
5833 to process the commands. Affected file silcd/command.c.
5834 Added new function silc_server_command_process_timeout.
5836 * Changed NICK_NOTIFY handling in client library to check that
5837 if the client's nickname was changed, so there is no need to
5838 resolve anything from the server.
5840 * Removed error printing from the WHOIS and IDENTIFY commands.
5841 If error occurs then it is ignored silently in the client library.
5842 The application, however, may map the received error to
5843 human readable error string. The application currently maps
5844 the NO_SUCH_NICKNAME error to string.
5846 * Made the command status message public to the application. Moved
5847 them from lib/silcclient/command_reply.c to
5848 lib/silcclient/command_reply.h. The application can map the
5849 received command status to the string with the
5850 silc_client_command_status_message function.
5852 * Added check to the server to check that client's ID is same
5853 as the Source ID in the packet the client sent. They must
5856 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Added dist-bzip hook to the Makefile.am to make bzip2
5859 compressed distributions.
5861 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Server now enforces the maximum length for the nickname and
5864 the channel as protocol specification dictates. 128 bytes for
5865 nickname and 256 bytes for channel name.
5867 * Moved the WHOIS printing to the application. The client libary
5868 does not print out the WHOIS information anymore, the application
5869 must do it. Renamed silc_client_command_reply_whois_print to
5870 the silc_client_command_reply_whois_save.
5872 The client's idle time is also sent to the application now, and
5873 the idle is shown on screen.
5875 * Added silc_client_command_reply_identify_save to save the
5876 received IDENTIFY entries.
5878 * Do not check for channel private keys in message sending and
5879 reception if the channel does not have the PRIVKEY mode set.
5880 Affected file lib/silclient/client_channel.c.
5882 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5885 just surfaced after chaning the JOIN procedure.
5887 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5889 * Added silc_client_get_clients_by_list to get client entries
5890 from Client ID list, that is returned for example by JOIN
5891 and USERS command replies. The application should use this
5892 function for example when JOIN command reply is received to
5893 resolve the clients already on the channel (library does not
5894 do that anymore as USERS command reply is not used in the JOIN
5895 procedure anymore). Affected files lib/silcclient/silcapi.h and
5896 lib/silcclient/idlist.c.
5898 * JOIN command reply and USERS command reply returns now SilcBuffer
5899 pointers instead of unsigned char pointers when returning
5900 the client list and mode list.
5902 * Added <Client ID> argument to the JOIN command reply, mainly
5903 for the server to identify for which client the command was
5904 originally sent. Updated protocol specs accordingly.
5906 * Added SilcDlist private_key pointer to the SilcChannelEntry
5907 in the client to support the channel private keys. Affected
5908 file is lib/silcclient/idlist.h.
5910 * Added SilcChannelPrivateKey argument to the function
5911 silc_client_send_channel_message so that application can choose
5912 to use specific private ke if it wants to. If it is not provided,
5913 the normal channel key is used, unless private keys are set.
5914 In this case the first (key that was added first) is used
5915 as the encryption key.
5917 * Implemented the support for channel private key handling.
5918 Implemented the following functions:
5920 silc_client_add_channel_private_key,
5921 silc_client_del_channel_private_keys,
5922 silc_client_del_channel_private_key,
5923 silc_client_list_channel_private_keys and
5924 silc_client_free_channel_private_keys
5926 Affected file lib/silcclient/client_channel.c.
5928 * Added the support for the private keys in the channel message
5929 sending and encryption and in the message reception and
5930 decryption. Affected funtions are
5931 silc_client_send_channel_message and silc_client_channel_message.
5933 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Added SKE's key verify callback to the client library's
5936 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5938 * Removed the statement that server (or router) must send USERS
5939 command reply when joining to the channel so that the client
5940 knows who are on the channel. Instead, the client list and
5941 client's mode list is now sent in the JOIN command reply to the
5942 client who joined channel. This is better solution.
5944 * Added function silc_server_get_users_on_channel and function
5945 silc_server_save_users_on_channel to the silcd/server.[ch].
5947 * Removed function silc_server_command_send_users from the
5950 * Do not show topic on the client library anymore. The topic is
5951 sent in the command reply notify to the application and the
5952 application must show the topic now.
5954 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Added client searching by nickname hash into the IDENTIFY and
5957 WHOIS commands in the server as they were clearly missing from
5958 them. Affected file is silcd/command.c.
5960 * Fixed a bug in private message receiving in the client library.
5961 The remote ID was freed and it wasn't supposed, now it is
5964 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Minor fix to the channel payload; allocate the data area, as it
5967 needs to be of specific length.
5969 * If the key agreement port is zero then the operating
5970 system will define the bound port. Affected files are
5971 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5973 * Added new function silc_channel_payload_decrypt into the file
5974 lib/silccore/silcchannel.[ch].
5976 * Moved the channel message etc, check from silc_packet_decrypt
5977 to applications. The library calls now a generic
5978 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5979 when the packet is either normal or special. This was done to
5980 allow more wide range of checking that was not allowed when
5981 the code was in library. Now applications can do virtually any
5982 checks to the packet and return to the library the decision how
5983 the packet should be processed. Affected files are
5984 lib/silccore/silcpacket.[ch].
5986 Added silc_server_packet_decrypt_check to the server and
5987 silc_client_packet_decrypt_check to the client library.
5989 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5990 to send with specified source and destination information.
5992 * Channel message delivery between routers was broken after the
5993 channel key distribution was fixed earlier. The channel key
5994 was used be to distributed to other routers as well which is not
5995 allowed by the protocol. Now this is fixed and channel keys
5996 really are cell specific and the channel message delivery between
5997 routers comply with the protocol specification.
5999 * Fixed various commands in server to check also the global list
6000 for the channel entry and not just the local list. The affected
6001 file silcd/command.c.
6003 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * Added assert()s to buffer formatting and unformatting routines
6006 to assert (if --enable-debug) when error occurs. Affected
6007 file: lib/silcutil/silcbuffmt.c.
6009 * Changed to auto-reconnect to check whether the remote host is
6010 router and register the re-connect timeout if it is. It used
6011 to check that whether we are normal server, but router must do
6012 auto-reconnect with another router as well. Affected file
6015 * Removed the [<key len>] option from CMODE command as the cipher
6016 name decides the key length, nowadays. See the defined ciphers
6017 from the protocol specification.
6019 * Added [<hmac>] option to the CMODE command to define the HMAC
6020 for the channel. Added SILC_CMODE_HMAC channel mode.
6022 * Added [<hmac>] option for the JOIN command so that user can
6023 select which HMAC is used to compute the MACs of the channel
6026 * Added Hmac field to the Channel Message Payload. The integrity
6027 of plaintext channel messages are now protected by computing
6028 MAC of the message and attaching the MAC to the payload. The
6029 MAC is encrypted. Now, it is clear that this causes some
6030 overhead to the size of the packet but rationale for this is that
6031 now the receiver can verify whether the channel message decrypted
6032 correctly and also when private keys are set for the channel the
6033 receiver can decrypt the packet with several keys and check from
6034 the MAC which key decrypted the message correctly.
6036 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6037 lib/silccrypt/silccipher.[ch].
6039 * Added silc_hash_len to return the digest length into the
6040 lib/silcrypt/silchash.[ch].
6042 * Rewrote parts of Silc Channel Payload interface in the
6043 lib/silccore/silcchannel.[ch]. The encode function now also
6044 encrypts the packet and parse function decrypts it.
6046 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6048 * Fixed a minor formatting bug in the SKE's key material processing.
6049 It actually might have processed the keys wrong way resulting
6052 * Redefined the mandatory HMAC algorithms and added new algorithms.
6053 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6054 and hmac-md5 truncated to 96 bits. The mandatory is now
6055 hmac-sha1-96. Rest are optional (including the one that used
6056 to be mandatory). Rationale for this is that the truncated HMAC
6057 length is sufficient from security point of view and can actually
6058 make the attack against the HMAC harder. Also, the truncated
6059 HMAC causes less overhead to the packets. See the RFC2104 for
6062 * Added new [hmac] configuration section. The SKE used to use
6063 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6064 is of course wrong. The official names that must be proposed in
6065 the SKE are the ones defined in the protocol specification
6066 (hmac-sha1-96 for example). The user can configure any hmac
6067 using any hash function configured in the [hash] section. At
6068 least, the mandatory must be configured.
6070 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6072 * Added HMAC list to the SKE proposal list. It has now both
6073 hash algorithm list and HMAC list. This makes the protocol
6074 incompatible with previous versions. The SKE now seems to work
6075 the way it is supposed to work, for the first time actually.
6077 * Defined plain Hash algorithms to the protocol specification.
6080 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Implemented support for key agreement packets into the server.
6083 Added functions silc_server_key_agreement and
6084 silc_server_send_key_agreement. Other than these functions,
6085 server has nothing to do with this packet.
6087 * Added support for private message key packets into the server.
6088 Added functions silc_server_private_message_key and
6089 silc_server_send_private_message_key.
6093 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6094 called in the protocol's final callback instead in the END
6095 protocol state. This makes a little more sense and in the same
6096 time in client we can use the same protocol routines for normal
6097 key exchange and to key agreement packet handling as well.
6099 * Added to both client's and server's KE protocol context the
6100 SilcSKEKeyMaterial pointer to save the key material. We will
6101 bring the key material to the protocol's final callback by doing
6102 this. The final callback must free the key material.
6104 * Added SKE's packet_send callback into client's KE protocol
6105 context so that the caller can choose what packet sending function
6106 is used. This way we can use different packet sending when
6107 doing normal SKE when doing key agreement packet handling (in
6108 the key agreement packet handling we do not want to encrypt
6111 * Implemented the responder side of the key agreement routines
6112 in the client. The client can now bind to specified port and
6113 accept incoming key negotiation. The key material is passed
6114 to the application after the protocol is over.
6116 * Implemented the processing of incoming Key Agreement packet
6117 in the client. Added function silc_client_key_agreement to
6120 * Implemented the intiator side of the key agreement routines
6121 in the client. The client can now initiate key agreement with
6122 another remote client. The key material is passed to the
6123 application after the protocol is over.
6125 * Created client_keyagr.c to include all the key agreement
6128 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6129 SILC_TASK_CALLBACK except that it is not static.
6131 * Created client_notify.c and moved the Notify packet handling
6132 from the client.[ch] into that file.
6134 * Created client_prvmsg.c and moved all private message and
6135 private message key routines from the client.[ch] into that file.
6137 * Create client_channel.c and moved all channel message and
6138 channel private key routines from the client.[ch] into that file.
6140 * Changed silc_client_get_client_by_id_resolve to resolve with
6141 WHOIS command instead of IDENTIFY command, in the file
6142 lib/silclient/idlist.c.
6144 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Implemented the SKE's responder side to the Client library.
6148 * When FAILURE is received to the protocol do not trust it
6149 blindly. Register a timeout to wait whether the remote closes
6150 the connection as it should do it, only after that process the
6151 actual failure. This was changed to both client and server.
6153 * Added client_internal.h to include some of the structures
6154 there instead of client.h in lib/silcclient/.
6156 * Added function silc_task_unregister_by_callback to unregister
6157 timeouts by the callback function.
6159 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Some "Incomplete WHOIS info" errors has been appearing on the
6162 log files. Took away the entry->userinfo check from WHOIS
6163 reply sending. The entry->userinfo is now " " if client did not
6164 provide one. I thought this was fixed earlier but something
6165 is wrong still. Let's see if the error still appears.
6167 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6169 * Fixed a minor bug in the login when the channel key is
6170 re-generated in the server. It used to generate the key in
6171 wrong order and thus caused problems in the channel traffic.
6173 * Fixed a minor bug in channel key distsribution after
6174 KICK command. The key was not sent to the router even though
6177 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Added silc_ske_process_key_material_data as generic routine
6180 to process any key material as the SILC protocol dictates. The
6181 function is used by the actual SKE library but can be used by
6182 applications as well. This relates to the private message keys
6183 and the channel private keys since they must be processed the
6184 same way the normal SILC session keys. The protocol dictates
6185 this. Affected files: lib/silcske/silcske.[ch].
6187 Added also silc_ske_free_key_material to free the
6188 SilcSKEKeyMaterial structure.
6190 * Defined silc_cipher_set_key function to set the key for
6191 cipher without using the object's method function. The affected
6192 files: lib/silccrypt/silccipher.[ch].
6194 * Implemented silc silc_client_add_private_message_key,
6195 silc_client_add_private_message_key_ske,
6196 silc_client_del_private_message_key,
6197 silc_client_list_private_message_keys and
6198 silc_client_free_private_message_keys functions in the
6201 Added functions silc_client_send_private_message_key to send
6202 the Private Message Key payload and silc_client_private_message_key
6203 to handle incoming Private Message Key payload.
6205 * Added Cipher field to the Private Message Key payload to set
6206 the cipher to be used. If ignored, the default cipher defined
6207 in the SILC protocol (aes-256-cbc) is used.
6209 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * Removed lib/silcclient/ops.h file.
6213 Redefined parts of the SILC Client Library API. Created new
6214 file silcapi.h that deprecates the ops.h file and defines the
6215 published Client Library API. Defined also private message key
6216 API and channel private key API into the file.
6218 This is the file that the application must include from the
6219 SILC Client Library. Other files need not be included by
6220 the application anymore.
6222 * Added new key_agreement client operation callback and also
6223 defined the Key Agreement library API for the application.
6225 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6228 is used by clients to request key negotiation between another
6229 client in the SILC network. If the negotiation is started it
6230 is performed using the SKE protocol. The result of the
6231 negotiation, the secret key material, can be used for example
6232 as private message key.
6234 Implemented the Key Agreement payload into the files
6235 lib/silccore/silauth.[ch].
6237 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Redefined ciphers for the SILC protocol. Added some new ciphers
6240 and defined the key lengths for the algorithms. Changed the
6241 code accordingly. The default key length is now 256 bits.
6243 * Fixed SKE key distribution function silc_ske_process_key_material
6244 when the key length is more than 128 bits. The default key
6245 length in SILC is now 256 bits.
6247 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6248 to indicate unsupported algorithm.
6250 * Renamed rijndael.c to aes.c and all functions as well.
6252 * Fixed a long standing channel key setting bug in client library.
6253 Weird that it has never surfaced before.
6255 * Fixed bug in channel deletion. If the entire channel is removed
6256 then it must also delete the references of the channel entry
6257 from the client's channel list as the client's channel entry and
6258 the channel's client entry share same memory.
6260 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Implemented CONNECT and SHUTDOWN commands in the client.
6264 * Implemented CLOSE command to the client.
6266 * Added the function silc_idlist_find_server_by_name into the
6267 files silcd/idlist.[ch].
6269 Added the function silc_idlist_find_server_by_conn into the
6270 files silcd/idlist.[ch].
6272 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * DIE command was renamed to SHUTDOWN. Updated the both code
6277 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6278 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6280 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6283 * Added function silc_server_create_connection function to create
6284 connection to remote router. My server implementation actually
6285 does not allow router to connect to normal server (it expects
6286 that normal server always initiates the connection to the router)
6287 so the CONNECT command is only good for connecting to another
6290 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6292 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6293 or some other client was kicked from the channel.
6295 Implemented the handling of the notify type to both client
6298 Implemented silc_server_send_notify_kicked to send the KICKED
6299 notify. It is used to send it to the server's primary router.
6301 * Implemented the KICK command into server and client.
6303 * Added `query' argument to the silc_idlist_get_client function
6304 to indicate whether to query the client from server or not if
6307 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6308 to indicate that the client is not channel founder.
6312 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Removed the rng context from SilcPacketContext structure and
6315 changed that the packet routine uses the Global RNG API.
6317 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6319 * Added support for quit message that client can "leave" on the
6320 channel when it quits the SILC. It is ditributed inside the
6321 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6323 Added silc_server_free_client_data that will take the
6324 signoff message as argument.
6326 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6328 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6330 * Updated parts of the protocol specification to keep it up
6333 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6336 payloads in one packet.
6338 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6339 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6340 use now the new List flag.
6342 * Also deprecated the following packet types: REPLACE_ID,
6343 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6345 * Added list support for Notify packet in server.
6347 * Added silc_server_send_notify_channel_change to send the
6348 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6349 the silc_server_send_replace_id.
6351 * Added silc_server_send_notify_nick_change to send the
6352 NICK_CHANGE notify type. Deprecates the function
6353 silc_server_send_replace_id.
6355 * Added silc_server_send_notify_join to send the JOIN notify type.
6356 Deprecates the function silc_server_send_new_channel_user.
6358 * Added silc_server_send_notify_leave to send LEAVE notify type.
6359 Deprecates the function silc_server_send_remove_channel_user.
6361 * Added silc_server_send_notify_cmode and
6362 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6363 types. Deprecates the silc_server_send_set_mode function.
6365 * Added SERVER_SIGNOFF notify type to indicate that server has
6366 quit. This means that all clients on the channel from that
6367 server will drop. This can be also used when netsplit happens.
6369 Deprecated REMOVE_ID packet type since it is not needed anymore
6372 Added silc_server_send_notify_server_signoff to send the
6373 SERVER_SIGNOFF notify type. Deprecates the function
6374 silc_server_send_remove_id.
6376 Added also silc_server_send_notify_signoff to send the
6377 SIGNOFF notify type.
6379 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6380 SILC protocol from this day on. Changed the protocol
6381 specification as well.
6383 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6384 notify type. It is used between routers to notify about
6385 topic changes on a channel.
6387 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6390 * Partly updated the protocol specification to comply with the
6391 changes now made. It is still though a bit outdated.
6393 * The JOIN notify type now takes one extra argument <Channel ID>.
6394 The packet used to be destined to the channel but now the
6395 JOIN type may be sent as list thus it is impossible to
6396 destine it to any specific channel. By adding this argument
6397 it is again possible.
6399 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6401 * Added CREDITS file. The CHANGES and CREDITS file will appear
6402 in the distribution as well.
6404 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6406 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6407 types in the server's silcd/packet_receive.c.
6409 * Implemented CMODE and CUMODE to work in router environment.
6411 * Fixed minor encoding and decoding buglet from the
6412 lib/silccore/silcmode.c.
6414 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6417 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6419 * Changed all SilcConfigServer* and silc_config_server* to
6420 SilcServerConfig* and silc_server_config*, respectively.
6423 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Associated the ID (client or server ID) to the Authentication
6426 Payload to avoid any possibility of forging. Updated the
6427 protocol specification and the code accordingly.
6429 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6431 * The RSA key length is now save to the RsaKey context in the
6432 key generation process in lib/silccrypt/rsa.c. The key length
6433 is now used to figure out the maximum size of the block allowed
6434 to be encrypted/signed.
6436 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6437 is equivalent to the silc_mp_mp2bin but does not allocate any
6440 * Changed silc_mp_mp2bin API to take length argument. If it is
6441 non-zero then the buffer is allocated that large. If zero, then
6442 the size is approximated using silc_mp_sizeinbase, which however
6445 * Created Global RNG API which is global RNG that application can
6446 initialize. After initializing, any routine anywhere in the
6447 code (including library) can use RNG without allocating a new
6448 RNG object. This was done to allow this sort of use of the
6449 RNG in code that has no chance to allocate RNG object. All
6450 applications currently allocate this and many routines in the
6451 library use this. Affected file lib/silccrypt/silcrng.[ch].
6453 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6454 it to use the Global RNG API.
6456 * Defined Authentication Payload into protocol specification that
6457 is used during SILC session to authenticate entities. It is
6458 used for example by client to authenticate itself to the server
6459 to obtain server operator privileges.
6461 Implemented this payload into the lib/silccore/silcauth.[ch].
6462 Implemented also routines for public key based authentication
6463 as the new protocol specification dictates.
6465 Moved definitions of different authentication methods from
6466 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6468 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6469 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6470 silc_pkcs_verify_with_hash functions into the file
6471 lib/silccrypt/silcpkcs.[ch].
6473 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * The client entry's userinfo pointer must be always valid.
6476 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6477 will fail since it requires the userinfo. Now, the userinfo
6478 is allocated as "" if actual userinfo does not exist. Actually,
6479 it must exist and it is totally Ok to drop client connections
6480 that does not announce the userinfo. However, we will make
6481 this workaround for now.
6483 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6484 to return the remote port by socket.
6486 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6489 SILC_SERVER_PENDING_EXEC and added an new macro
6490 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6491 data or when error occurs while processing the pending command.
6493 Added new argument `destructor' into silc_server_command_pending
6494 and to the SilcServerCommandPending object. This destructor is
6495 now called after calling the pending callback or if error occurs
6496 immediately. If error occurs the actual pending callback won't
6497 be called at all - only the destructor. The destructor may be
6498 NULL if destructor is not needed.
6500 All this applies for client library code as well. Similar
6501 changes were made there as well for the pending commands.
6503 In the client, the application must now allocate the
6504 SilcClientCommandContext with the silc_client_command_alloc
6507 * Added reference counter to the SilcServerCommandContext. Added
6508 function silc_server_command_alloc and silc_server_command_dup
6511 Same type of functions added to the client library for the same
6514 * Removed the cmd_ident from IDListData away since it is now
6515 global for all connections. It is the command identifier used
6516 in command sending and with pending commands. The affected file
6519 * Added reference counter to the SilcSocketConnection objecet to
6520 indicate the usage count of the object. The object won't be
6521 freed untill the reference counter hits zero. Currently only
6522 server uses this, and client ignores it. The client must be
6523 set to use this too later. The affected files are
6524 lib/silccore/silcsockconn.[ch]. Added also the function
6525 silc_socket_dup to increase the reference counter.
6527 This was mainly added because it is possible that the socket
6528 is removed underneath of pending command or other async
6529 operation. Now it won't be free'd and proper DISCONNECTING
6530 flags, etc. can be set to avoid sending data to connection that
6531 is not valid anymore.
6533 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6534 the connection. After that it sets SILC_SET_DISCONNECTED.
6535 It is, however, possible that the socket data is not still freed.
6536 The silc_server_packet_process now checks that data is not
6537 read or written to connection that is DISCONNECTED. The socket
6538 get's freed when the reference counter hits zero.
6540 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6542 * Changed the client operation API: channel_message operation's
6543 `sender' is now the client entry of the sender, not the nickname
6544 and the `channel' is the channel entry, not the channel name.
6546 In the private_message operation the `sender' is now also the
6547 client entry of the sender not the nickname.
6549 Affected file is lib/silcclient/ops.h and all applications
6550 using the client operations.
6552 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6554 * Moved the calling of ops->connect() from connect_to_server_final
6555 into receive_new_id functin since that is the point when the
6556 client is actually allowed to send traffic to network. The
6557 affected file is lib/silcclient/client.c.
6559 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6562 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6563 (if needs broadcasting) instead of broadcasting the packets one
6564 by one which would make a burst in the network traffic.
6566 * Added `broadcast' argument to the functions in silcd/server.[ch]
6567 silc_server_create_new_channel[_with_id] to indicate whether
6568 to send New Channel packet to primary router.
6570 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6572 * Added new function into the silcd/server.[ch] files:
6573 silc_server_create_new_channel_with_id to create new channel with
6574 already existing Channel ID.
6576 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6577 lib/silccore/silcpacket.h. This packet is used t send list of
6578 Set Mode payloads inside one packet. Server uses this to set
6579 the modes for the channels and clients on those channels, that it
6580 announced to the router when it connected to it. The protocol
6581 specification has been updated accordingly.
6583 * The silc_server_new_channel did not handle the packet coming
6584 from normal server as it normally does not send that. However,
6585 when it announces its channels it does send it. Implemented
6586 the support for that.
6588 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6589 into the file lib/silccore/id.h.
6591 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Fixed memory leaks in the functions silc_idlist_del_client,
6594 silc_idlist_del_channel and silc_idlist_del_server in the file
6595 silcd/idlist.c. All of those leaked like a sieve.
6597 * Fixed some small memory leaks in the client's function
6598 silc_client_notify_by_server.
6600 * Added functions into silcd/server.c: silc_server_announce_clients,
6601 silc_server_announce_channels and silc_server_announce_server.
6602 These functions are used by normal and router server to announce
6603 to its primary router about clients, channels and servers (when
6604 router) that we own. This is done after we've connected to the
6607 These functions effectively implements the following packet types:
6608 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6609 and SILC_PACKET_NEW_ID_LIST.
6611 * Added new functions into the silcd/packet_receive.[ch]:
6612 silc_server_new_id_list, silc_server_new_channel_list and
6613 silc_server_new_channel_user_list to handle the incoming
6614 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6616 * Added support of changing Channel ID in the function
6617 silc_server_replace_id. If the server that announces a channel
6618 to the router already exists in the router (with same name but
6619 with different Channel ID), router is responsible to send
6620 Replace ID packet to the server and force the server to change
6621 the Channel ID to the one router has.
6623 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6624 client that the Channel ID has been changed by the router. The
6625 normal server sends this to the client. Client must start using
6626 the new Channel ID as the channel's ID.
6628 Implemented handling of this new type into lib/silcclient/client.c
6629 into the function silc_client_notify_by_server.
6631 * Added new function silc_idlist_replace_channel_id into the files
6632 silcd/idlist.[ch] to replace the Channel ID.
6634 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6636 * Call silc_server_command_identify_check always when processing
6637 the IDENTIFY command in silcd/command.c
6639 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6641 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6642 send keepalive packets. The packet can be sent by clients,
6643 servers and routers.
6645 Added function silc_socket_set_heartbeat into the file
6646 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6647 If not set, the heartbeat is not performed. The actual
6648 heartbeat is implemented in the low level socket connection
6649 library. However, application is responsible of actually
6652 Added silc_server_send_heartbeat to send the actual heartbeat
6653 packet into silcd/packet_send.[ch]. Server now performs
6654 keepalive with all connections.
6656 * Added silc_task_get_first function into lib/silcutil/silctask.c
6657 to return the timeout task with shortest timeout. There was a bug
6658 in task unregistration that caused problems. TODO has been
6659 updated to include that task system must be rewritten.
6661 * The client library will now resolve the client information when
6662 receiving JOIN notify from server for client that we know but
6663 have incomplete information.
6665 * Rewrote parts of silc_server_remove_from_channels and
6666 silc_server_remove_from_one_channel as they did not remove the
6667 channel in some circumstances even though they should've.
6669 * Encryption problem encountered in server:
6671 The LEAVE command used to send the Channel Key packet to the
6672 router immediately after generating it. However, the code
6673 had earlier sent Remove Channel user packet but not immediately,
6674 ie. it was put to queue. The order of packets in the router
6675 was that Channel Key packet was first and Remove Channel User
6676 packet was second, even though they were encrypted in the
6677 reverse order. For this reason, MAC check failed. Now, this
6678 is fixed by not sending the Channel Key packet immediately but
6679 putting it to queue. However, this is more fundamental problem:
6680 packets that are in queue should actually not be encrypted
6681 because packets that are sent immediately gets encrypted
6682 actually with wrong IV (and thus MAC check fails). So, packets
6683 that are in queue should be encrypted when they are sent to
6684 the wire and not when they put to the queue.
6686 However, the problem is that the current system has not been
6687 designed to work that way. Instead, the packet is encrypted
6688 as soon as possible and left to the queue. The queue is then
6689 just purged into wire. There won't be any fixes for this
6690 any time soon. So, the current semantic for packet sending
6693 o If you send packet to remote host and do not force the send
6694 (the packet will be in queue) then all subsequent packets to the
6695 same remote host must also be put to the queue. Only after the
6696 queue has been purged is it safe again to force the packet
6699 o If you send all packets immediately then it safe to send
6700 any of subsequent packets through the queue, however, after
6701 the first packet is put to queue then any subsequent packets
6702 must also be put to the queue.
6704 Follow these rules and everything works fine.
6706 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6708 * Added new function silc_server_remove_clients_by_server to
6709 remove all client entries from ID list when the server connection
6710 is lost. In this case it is also important to invalidate all
6711 client entires as they hold the invalid server entry. This
6712 fixes fatal bug when server has lost connection and will reconnect
6715 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6717 * Made some sanity checks to silc_server_daemonise like to check
6718 whether the requested user and group actually exists.
6720 * Added sanity check to SKE's silc_ske_responder_finish to check
6721 that the public and private key actually is valid.
6723 * Invalidate the client's nickname when receiving Replace ID
6724 packet and the Client ID is being replaced. This means that the
6725 server will query the nickname if someone needs it (client)
6728 * Sort the ID Cache in client library when the ID Cache data
6729 has changed (needs sorting).
6731 * Do not allow for SILC client to create several connections to
6732 several servers. The client does not support windows right now
6733 and generating multiple connections causes weird behaviour.
6735 Irssi-silc client does support windows and can handle several
6736 connections without problems, see: www.irssi.org and SILC plugin.
6738 * Fixed some places where client was added to the IDList. The
6739 rule of thumb is following (in order to get everything right):
6740 If the client is directly connected local client then the
6741 `connection' argument must be set and `router' argument must be
6742 NULL to silc_idlist_add_client function. If the client is not
6743 directly connected client then the `router' argument must
6744 bet set and the `connection' argument must be NULL to the
6745 silc_idlist_add_client function.
6747 * The funtion silc_server_packet_send_local_channel actually did
6748 not check whether the client was locally connected or not. It
6749 does that now. Fixed a bug related to LEAVE command.
6751 * Fixed Remove Channel User payload parsing bug in server's
6752 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6754 * The server's silc_server_save_channel_key now checks also the
6755 global ID list for the channel as it might not be in the local
6756 list. Fixed a bug related to LEAVE command.
6758 * Is this the end of the [<unknown>] buglet that has been lurking
6759 around for a long time? A little for loop fix in server's
6760 silc_server_command_whois_parse that is used by both IDENTIFY
6761 and WHOIS command. At least, this was a clear bug and a cause
6762 of one type of [<unknown>] buglet.
6764 * WHOIS and IDENTIFY commands call the function
6765 silc_server_command_[whois/identify]_check function even if
6766 we are not router server.
6768 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6770 * Added --with-gmp configuration option. If set the GMP
6771 is always compiled in the SILC source tree. If not set then
6772 it is checked whether the system has the GMP3 installed. If
6773 it has then the GMP won't be compiled (the system's headers
6774 and library is used), if it doesn't have it then the GMP is
6775 compiled in the SILC source tree.
6777 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6779 * Changed RSA private exponent generation to what PKCS #1
6780 suggests. We try to find the smallest possible d by doing
6781 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6782 not security fix but optimization.
6784 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6786 * Added new config entry [Identity] to fork the server and run
6787 it as specific user and group. A patch from Bostik.
6789 * Imported Dotconf configuration library into lib/dotconf.
6790 This will be used to create the SILC configuration files later.
6791 It will appear in the distsribution after this commit.
6793 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * A big code auditing weekend happening. Auditing code for
6796 obvious mistakes, bugs and errors. Also, removing any code
6799 Removed files for being obsolete:
6801 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6802 inline in the file lib/silcutil/silcbuffer.h)
6804 o lib/silcutil/silcbufutil.c (the header has inline versions)
6806 Changed code to fix possible error conditions:
6808 o The buffer formatting routines now check that the destination
6809 buffer really has enough space to add the data. This applies for
6810 both buffer formatting and unformatting
6811 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6812 unformatting was changed to accomodate following rules:
6813 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6814 sent to the function while XXX_*STRING will not allocate or copy
6815 the data into the buffer. Instead it sets the pointer from the
6816 buffer into the pointer sent as argument (XXX_*STRING used to
6817 require that the pointer must be allocated already). This change
6818 makes this whole thing a bit more consistent and more optimized
6819 (note that the data returned in the unformatting with XXX_*STRING
6820 must not be freed now). The routines return now -1 on error.
6822 o Tried to find all code that use buffer_format and buffer_unformat
6823 and added return value checking to prevent formatting and
6824 especially unformatting errors and possible subsequent fatal
6827 o Changed ske->x and ske->KEY to mallocated pointers in
6828 lib/silcske/silcske.h. Fixed possible data and memory leak.
6830 o Added return value checking to all *_parse* functions. Fixed
6831 many memory leaks as well.
6833 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6834 so that buffer overflows would not happen. All code now also
6835 checks the return value as it can fail.
6837 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6839 * Added reconnection support to server if the normal server looses
6840 its connection to the router (for example if router is rebooted).
6841 The server performs normal reconnection strategy implemented
6842 to the server. Affected file silcd/server.c.
6844 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6846 * Added new packet type SILC_PACKET_SET_MODE that is used to
6847 distribute the information about changed modes (for clients,
6848 channels and clients channel modes) to all routers in the
6849 network. Updated the protocol specification accordingly.
6851 Added functions into silcd/packet_send.c and
6852 silcd/packet_receive.c: silc_server_send_set_mode,
6853 silc_server_set_mode.
6855 Added new files silcmode.[ch] into lib/silccore that implements
6856 the encoding and decoding of Set Mode Payload. Added new type
6857 SilcSetModePayload. Moved the definitions of different modes
6858 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6860 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Oops, a little mistake in server's connection authentication
6863 protocol. The protocol is not ended with FAILURE but with
6864 SUCCESS if the authentication is Ok. :) Affected file is
6867 * Implemented NICK_CHANGE notify handling in server in the file
6868 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6869 the local clients on the channel. After the changing nickname
6870 in router environment snhould work and the [<unknown>] nickname
6871 should appear no more.
6873 The silc_server_replace_id function that receives the Replace ID
6874 payload now sends the NICK_CHANGE notify type also in the file
6875 silcd/packet_receive.c
6877 * Changed WHOIS and IDENTIFY command to support the maximum amount
6878 of arguments defined in protocol specs (3328 arguments). This
6879 fixed a bug that caused problems when there were more than three
6882 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6884 * Added extra parameter, command identifier, to the
6885 silc_client_send_command so that explicit command identifier
6888 Changed that ID list routines uses specific command identifier
6889 when sending WHOIS/IDENTIFY requests to the server so that they
6890 can be identified when the reply comes back.
6892 Affected files lib/silcclient/command.[ch],
6893 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6895 * Added `sender' argument to silc_server_packet_send_to_channel
6896 to indicaet the sender who originally sent the packet to us
6897 that we are now re-sending. Ignored if NULL. Affected file
6898 silcd/packet_send.[ch].
6900 * Added some server statistics support in silcd/server_internal.h
6901 SilcServerStatistics structure and around the server code. Also
6902 send some nice statistics information when client is connecting
6905 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6907 * Fixed channel ID decoding in server's JOIN command reply in
6908 silcd/command_reply.c
6910 * Fixed braodcasting of replace ID payload to not to send it if
6911 we are standalone server in silcd/packet_receive.c.
6913 * Fixed all channel message sending routines to not to send
6914 packets to clients that has router set, since they are routed
6915 separately in the same function earlier. Affects file
6916 silcd/packet_send.c and all channel packet sending functions.
6918 * In USERS reply, res_argv[i] are not allocated, the table
6919 is allocated. Thus changed that free the table, not its
6922 * In server's whois_check and identify_check if the client is
6923 locally connected do not send any WHOIS commands - they are not
6926 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6928 * Fixed some minor bugs in client when sending WHOIS command. The
6929 arguments was in wrong order.
6931 * Removed statis function add_to_channel from server in
6932 silcd/command.c that was previously used with the joining but
6935 * Tested USERS command in router environment successfully with two
6936 routers, two servers and two clients.
6938 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6940 * Reorganized the USERS command and command reply in client library
6941 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6942 When the command is given by user we register a pending command
6943 callback that will reprocess the command after the reply has been
6944 received from the server. When reprocessing the packet we then
6945 display the information. Thus, the USERS information is displayed
6946 now in the command callback instead of in the command reply
6947 callback. The processing of the command is same as previously
6948 when server has sent the command reply in the JOINing process.
6950 * Added to USERS command in silcd/command_reply.c to join the client,
6951 we didn't use to know about, to the channel after we've created
6952 a client entry for it. Also, for clienet we did know already still
6953 check whether it is on the channel or not and add it if not.
6955 * Removed silc_server_command_join_notify as the function and its
6958 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6960 * Changed the client's pending command handling to the same as the
6961 server's pending command handling. It is also now possible to
6962 execute command reply functions from other command reply
6963 function as the function callbacks for commands and command
6964 replies are one and same. The pending commands are not static
6965 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6966 in client connection context. Thus, pending commands are server
6967 connection specific as it is convenient.
6969 Changed the function silc_client_command_pending and
6970 silc_client_command_pending_del and added new function
6971 silc_client_command_pending_check. Removed the
6972 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6975 * Added cmd_ident, current command identifier, to the client
6976 connection context in lib/silcclient/client.h to keep track on
6977 command identifiers used in command sending. Client's command reply
6978 function handling now supports the mandatory command identifiers.
6980 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6981 funtions in client to fully support pending command callbacks.
6983 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6984 as one of the arguments to the application in the command reply
6987 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6988 before first releasing SILC but came back. Now it is removed again
6989 and should come back nomore. The FORWARDED flag was used only
6990 by the JOINing procedure by forwarding the command packet to router.
6991 Now, the JOINing procedure has been changed to more generic (due
6992 to various router environment issues) and FORWARDED is not needed
6993 anymore for anything. The protocol specification is yet to be
6996 Now, removed silc_server_packet_forward from server and the flag
6997 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6999 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7001 * Renamed NAMES command to USERS command. The NAMES was named that
7002 due to historical reasons. Now it is renamed. Also, rewrote
7003 parts of the USERS command. The nickname list is not sent anymore
7004 by the server. Only Client ID and mode lists are sent in the USERS
7005 command. Changed this also to the protocol specification.
7007 The client now resolves the names and stuff after it receives
7008 the USERS list from the server when joining to the channel.
7010 * WHOIS and IDENTIFY commands has been changed to support multiple
7011 Client ID's per command. One can now search for multiple users
7012 in the network by sending only one WHOIS or IDENTIFY command.
7013 Changed the code and the protocol specifications.
7015 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7016 uses silc_server_command_whois_parse to parse the request. */
7018 * If normal server, do not parse the WHOIS and IDENTIFY requests
7019 before sending it to the router. Saves some time.
7021 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7023 * Fixed JOIN command on client library. Wrong number of arguments
7024 used to crash the client.
7026 * Added silc_server_channel_has_global function to check whether
7027 channel has global users or not.
7029 * Added silc_server_channel_has_local function to check whether channel
7030 has locally connected clients on the channel.
7032 * The silc_server_remove_from_one_channel now checks whether the
7033 channel has global users or not after given client was removed from
7034 the channel. It also checks whether the channel has local clients
7035 on the channel anymore. If it does not have then the channel entry
7036 is removed as it is not needed anymore.
7038 * The silc_server_notify now checks on JOIN notify whether the joining
7039 client is one of locally connected or global. If it is global then
7040 the channel has now global users on the channel and that is marked
7041 to the channel entry. Also, it now saves the global client to
7042 global list who is joining and JOINs it to the channel. This is
7043 for normal server, that is.
7045 Changed silc_server_send_notify_on_channel,
7046 silc_server_packet_relay_to_channel and
7047 silc_server_packet_send_to_channel check if we are normal server
7048 and client has router set (ie. global client) do not send the
7049 message to that client, as it is already routed to our router.
7051 * Implemented LEAVE notify type handling in silc_server_notify
7054 * Tested LEAVE command in router environment successfully. Tested
7055 with two routers, two servers and two clients.
7059 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7061 * Implemented SIGNOFF notify type handling in silc_server_notify
7064 * silc_server_remove_id now removes the client entry from all channels
7065 it has joined and thusly sends SIGNOFF notify type.
7067 * Rewrote the NAMES list generation in server by removing two excess
7068 loops. The lists are created now inside one loop.
7070 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7072 * silc_server_remove_channel_user checks now also global list
7073 for channel and client.
7075 * silc_server_new_channel_user checks now both local and global
7076 list for channel and client. Fixed a bug in client id decoding.
7077 Used to decode wrong buffer.
7079 * silc_server_channel_message checks now both local and global
7080 list for channel entry.
7082 * Tested channel joining (hence JOIN) in router environment
7083 successfully. Tested with two routers, two servers and two
7086 * Tested channel message sending in router environment successfully.
7088 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7090 * Added silc_server_save_channel_key into server.[ch] to save the
7091 received channel key in Channel Key payload processing. It is
7092 also used in JOIN command reply handling.
7094 Equivalent function silc_client_save_channel_key added into
7095 client.[ch] into client library.
7097 * Changed JOIN command reply to send information whether the channel
7098 was created or not (is existing already) and the channel key
7099 payload. Changed protocol specs accordingly.
7101 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7102 the request was sent by ID and not by nickname. Crashed on
7105 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7107 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7108 now correctly save the received data.
7110 * silc_server_free_sock_user_data now notifies routers in the
7111 network about entities leaving the network.
7113 At the same time implemented functions silc_server_remove_id
7114 and silc_server_send_remove_id to receive and send REMOVE_ID
7115 packets. The packet is used to notify routers in the network
7116 about leaving entities. The ID removed will become invalid in
7119 * Added function silc_idlist_del_server into server. Removes and
7120 free's server entry from ID list.
7122 * silc_server_private_message function now checks, if we are router,
7123 that the destination ID really is valid ID, naturally.
7125 * In router when NEW_ID packet is received (for new client) the
7126 hash of the Client ID is saved in the ID Cache but the
7127 client->nickname is set to NULL, instead of putting the hash
7130 IDENTIFY command now also checks that client->nickname must be
7131 valid. If it is not if will request the data from the server who
7132 owns the client. Added new function
7133 silc_server_command_identify_check.
7135 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7136 to set the command to already allocated Command Payload.
7138 * Tested private message sending in router environment with two
7139 routers, two servers and two clients. Fixed minor bugs and now
7142 * Fixed segfault from client's NAMES command. Used to crash if
7145 * Forwarded packets must not be routed even if it is not destined
7146 to the receiver. Changed server code comply with this.
7148 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7150 * Added `require_reverse_mapping' boolean value to ServerParams
7151 structure. If TRUE (not default) the server will require that
7152 the connecting host has fully qualified domain name.
7154 If the reverse mapping is not required and hostname could not be
7155 found the IP address is used as hostname.
7157 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7159 * Implemented version string checking to both client and server.
7160 The check is incomplete currently due to the abnormal version
7161 strings used in development version of SILC.
7163 * Changed all command functions in server to use the new
7166 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7168 * Changed char *data to unsigned char *data in ID Cache system to
7169 support binary data as ID Cache data. Changed code to support
7170 binary data in lib/silccore/idcache.c.
7172 * Renamed silc_server_packet_relay_command_reply to
7173 silc_server_command_reply as it is normal packet receiving
7174 function. Rewrote the function to accept command replys for
7175 servers and not only for clients.
7177 * Mark remote router always as registered server if we are connecting
7178 to it. Otherwise, commands sent by the router to us are ignored.
7180 * All ID List find routines now returns the ID Cache Entry pointer
7181 as well if requested.
7183 * WHOIS command works now in router environment, tested with two
7184 routers, two servers and two clients.
7186 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7187 in router environment (as it is almost equivalent to WHOIS) but
7188 hasn't been tested thoroughly. Added new functions:
7190 silc_server_command_identify_parse
7191 silc_server_command_identify_send_reply
7192 silc_server_command_identify_from_client
7193 silc_server_command_identify_from_server
7195 * Disabled route cache adding because adding two different ID's with
7196 same IP replaces the old cache entry thus giving wrong route.
7197 The entry->router->connection is always the fastest route anyway
7198 so route cache may not be needed. Of course, new routes maybe
7199 established after receiving the ID when the entry->router->connection
7200 might not be anymore the most optimal.
7202 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7204 * Add route cache for received ID for fast routing.
7206 * Added silc_server_packet_route to route received packet on router
7207 that is not destined to us.
7209 * Renamed silc_server_get_route to silc_server_route_get.
7211 * Added id_string and id_string_len fields into SilcServer to
7212 include encoded ServerID for fast comparing without excess
7213 encoding of the ID's.
7215 * Cleaned up WHOIS command on server side. Added following static
7218 silc_server_command_whois_parse
7219 silc_server_command_whois_check
7220 silc_server_command_whois_send_reply
7221 silc_server_command_whois_from_client
7222 silc_server_command_whois_from_server
7224 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7225 arguments in command replies. All command functions should be
7226 updated to use this macro.
7228 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Minor typo fixes on command reply handling on server.
7232 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7234 * Added silc_server_command_add_to_channel internal routine to add
7235 the client to the channel after router has created the channel and
7236 sent command reply to the server.
7238 * Added generic silc_server_send_command to send any command from
7241 * Use static buffer with ID rendering instead of duplicating data.
7243 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7245 * Fixed a channel user mode bug when joining to a channel server gave
7246 everybody channel founder rights, oops.
7248 * We mark ourselves as the router of the incoming server connection
7249 if we are router ourselves. This way we can check in some packet
7250 sending functions whether it is locally connected server. For
7251 incoming router connections we put NULL.
7253 * For router sending packets locally means now always sending the
7254 packet cell wide; to local clients and local servers. For normal
7255 server sending packet locally means sending it to only local
7258 * Fixed the JOIN command to really work in router environment. If the
7259 channel is created it is always created by the router. Router is
7260 also responsible of making the initial joining to the channel,
7261 sending JOIN notify to the sending server and distributing
7262 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7263 does not exist server doesn't do anything else but forward the
7264 command to the router which performs everything.
7266 * Added silc_server_send_channel_key function to send the Channel Key
7269 * Added silc_server_create_channel_key to create new channel key. The
7270 channel key is now re-generated everytime someone joins or leaves
7271 a channel, as protocol dictates. Note: channel->key_len is the
7274 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7276 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7277 packet_receive.[ch] to separate packet sending and receiving
7278 routines. The server.[ch] now includes everything else including
7279 actual packet processing (writing and reading data) and other
7282 Renamed silc_server_private_message_send_internal to
7283 silc_server_send_private_message. The routine is still though
7284 used only to relay private messages as server does not send
7285 private messages itself.
7287 Renamed silc_server_new_channel to silc_server_create_new_channel
7288 and added new function sicl_server_new_channel that handles the
7289 incoming New Channel packet. Added also new sending function
7290 silc_server_send_new_channel to send New Channel Payload.
7292 * Added new function silc_server_notify to process incoming notify
7293 packet to the server/router. Server may then relay the notify
7294 to clients if needed.
7296 * Added new function silc_server_new_channel_user to process incoming
7297 New Channel User packet. Router will redistribute the packet and
7298 send JOIN notify to its local clients and locally connected servers
7299 if needed. Normal server will send JOIN notify to its local client
7300 on same channel when received this packet. Added also corresponding
7301 sending function silc_server_send_new_channel_user to sent the
7304 * Added boolean route argument to send_notif_to_channel and
7305 packet_send_to_channel functions to attempt to route the packet
7306 if it is TRUE and send only locally if it is FALSE.
7308 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7310 * silc_server_replace_id now broadcasts the received replace ID
7311 packet if it is not broadcast packet already. The router must
7312 broadcast to inform other routers about changed ID.
7314 * Added backpointer to server's router into SilcServer context in
7315 silcd/server_internal.h.
7317 * Fixed silc_server_packet_broadcast to send correct broadcast
7320 * The channel key is now distributed to the local client as soon
7321 as it is received from the router (in router environment) so that
7322 no other packet may be sent for the channel until client has
7325 * silc_server_remove_channel_user now broadcasts the received
7326 Remove Channel User packet if it is not broadcast packet already.
7327 The router must broadcast to inform other routers about removed
7330 * Added users field into SilcPacketContext that is a reference count
7331 of the context. One can increase the reference count by calling
7332 silc_packet_context_dup which is now changed to just increase the
7333 reference count instead of duplicating the data. The reference
7334 count is decresed by calling silc_packet_context_free that will
7335 free the data after the reference count hits zero.
7337 For now on the packet context and everything allocated into it
7338 (including the raw packet from network) must be freed by calling
7339 the new silc_packet_context_free function. Added also new function
7340 silc_packet_context_alloc that must be used now to allocate the
7341 context. This also means that if a routine is asynchronous from
7342 silc_[client/server]_packet_parse_type the packet context must
7343 be duplicated by calling silc_packet_context_dup. Otherwise it
7344 gets free'd after silc_[client/server]_packet_parse_type returns.
7345 Also, one must remember that if packet is duplicated then its
7346 reference count must be decresed by calling the free function as
7347 many times as it was duplicated.
7349 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7350 from both client and server.
7352 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7354 * Made joining to a channel working in router environment.
7356 * Cleaned up JOIN command on server side and create function
7357 silc_server_command_join_channel internal routine to make the
7360 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7362 * Changed silc_command_pending list to SilcDList. Also, added
7363 `ident' field to SilcServerCommandPending structure to identify
7364 the reply and to call correct callback.
7366 Added silc_server_command_pending_check function to replace the
7367 corresnponding macro. The silc_command_pending list is not
7370 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7371 to set identifier to previously allocated Command Payload. It
7372 is used to set identifier for command when resending Command
7375 * Added silc_command_payload_encode_payload to encode Command
7376 Payload buffer from SilcCommandPayload structure.
7378 * Added silc_argument_payload_encode_payload to encode Argument
7379 payload buffer from SilcArgumentPayload structure.
7381 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7383 * Changed WHOIS command to support router connection on server side.
7384 The whois request is always sent to router unless the server is
7385 standalone server. After server has received the reply from the
7386 router will it send the reply to the client.
7388 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7389 broadcast received broadcast packet. The function is used only
7390 by router. The broadcast packet is always sent to the router's
7393 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7394 render given ID to printable string, for log files for example.
7396 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7398 * Made basic router to router connections working. At least they
7399 can now connect to each other but nothing really works the way
7400 they are supposed - yet.
7402 * Added new initiator token to RouterConnection configuration
7403 file in silcd/serverconfig.[ch]. It is used to tell whether we
7404 are the initiator to the remote router or whether we'll expect
7405 the other end to connect.
7407 * Moved registering of listener task to silc_server_init, hence
7408 the server starts listenning as soon as it is run, even if it
7409 does not have connections to other routers. Let's see how well
7412 * Changed default connection retry timeouts for more suitable in
7415 * Removed cipher and such arguments from silc_idlist_add_client
7416 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7417 Added new function silc_idlist_add_data to add the keys and stuff
7420 * Added SilcIDListData structure and added it to SilcClientEntry
7421 and SilcServerEntry as their first field in the structure. This
7422 way we can explicitly cast the ID entries to the SilcIDListData
7423 structure and get common data for the entries. In past, we had
7424 to first check what type of connection it is and then cast it to
7425 correct ID entry type. Now, we can directly cast the opaque
7426 pointer to the SilcIDListData (no matter what ID entry it actually
7427 is) and get the data needed.
7429 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7431 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7432 in some circumstances even if threre were timeout tasks, though not
7433 IO tasks, but tasks anyway. Now fixed.
7435 * Defined SilcServerConnection structure to hold connection specific
7436 stuff about directly connected servers and routers. The definition
7437 is currently in silcd/server_internal.h. I thought about having
7438 a bit more important role fro this struct but for now it is used
7439 only when connecting to other server (or router actually).
7441 * Added connecting retry support in server when connecting to
7442 router(s). The retry feature implement exponential backoff
7443 algorithm. Also, added SilcServerParams structure to hold default
7444 parameters for server. For now, it include these retry settings
7445 and are hard coded. After server is moded to be as Silc Server
7446 Library this structure will be more important.
7448 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7450 * Changed client librarys channel->clients table to SilcList and
7451 changed code accordingly.
7453 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7455 * Changed client's channel table to SilcList and changed code
7456 accordingly. Also changed SilcChannelClientEntry to include back-
7457 pointer to the channel so that client entry can use that structure
7458 as list as well and we have fast cross-reference to the channel.
7459 This change dramatically decreased the complexity of channel
7460 handling with client entry and vice versa (removed one extra
7461 loop when searching for channel entry from many functions).
7463 * Changed server->sim from table to SilcDList and changed code
7466 * NAMES command can now be used from user interface. It will show
7467 the user list on the channel, neatly.
7469 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7470 Code now saves realname of the user if it becomes available.
7472 * Renamed configure.in to configure.in.pre and made ./prepare
7473 script to automatically add correct version string to
7474 configure.in which it creates from configure.in.pre.
7476 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7478 * NAMES command reply now shows users mode with the nickname when
7481 * Moved silc_client_ch[u]mode[_char] functions from
7482 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7483 place sucks, they are utility functions and should be in some
7486 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7488 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7491 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Added TRQ (efficient deque and list library) into lib/trq. This is
7496 a very good list library that is currently used in the SILC. Defined
7497 SilcList API over the library because I didn't like the API very
7498 much. See lib/trq/silclist.h for the API and examples of how to
7499 use the API. Fixed various places in the code to use the new
7500 SilcList API. The SilcList is meant for lists that has a structure
7501 already defined as a list. It is not suitable to add just some
7502 context to the list (in TRQ, the context is the list actually).
7504 So, I defined SilcDList that can be used for the purpose where
7505 predefined list structure does not exit. This can be used as
7506 such list. Now some context just can be added to the SilcDList.
7507 Currently this list is not used in the SILC just yet, though there
7508 are a lot places where this can replace dynamically allocated
7509 tables and I will fix these places, later, to use SilcDList.
7510 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7511 and use TRQ internally).
7513 Also fixed some annoying warning messages that the original TRQ
7514 code generated. Also minor changes to TRQ's Makefile.in.
7516 * Added support for querying by Client ID to both WHOIS and
7517 IDENTIFY commands into server, as required by the protocol.
7519 * Removed method function pointers from SilcBuffer structure. They
7520 weren't used to anything and just increased the context size for
7521 no good reason. This change also made silc_buffer_alloc and
7522 silc_buffer_free functions inline functions.
7524 * Disabled command flooding detection support until it's fixed so
7525 that it accepts commands in but does not execute them more than once
7528 * Added silc_net_localhost(), to return local hostname, into
7529 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7530 that must be initialized before calling silc_client_init.
7532 * Added new function: silc_server_send_notify_on_channels to send
7533 notify messages to all channels client has joined. It is assured
7534 that the message is sent only once per client.
7536 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7537 lib/silcutil/silcutil.[ch] as silc_format function. The new
7538 function is generic and is used by server as well, not only by
7539 the logging routines.
7541 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7542 the provided version string was not acceptable. Added new function:
7543 silc_ske_check_version into lib/silcske/silcske.h. The function
7544 must be implemented by the application (client or server) and it
7545 does not reside in the SKE library. The function checks the version
7546 string remote end sent.
7548 * Added back pointers (to opaque context and to SilcSocketConnection)
7549 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7551 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7552 duplicate packet context structure.
7554 * Changed `notify' client operation to send same arguments as client
7555 receives from server except for ID's. ID's are mapped to correct
7556 ID entry and that is returned. Also, if channel entry is not sent
7557 by server but the notify is for channel the channel entry is sent
7558 to application (otherwise application doesn't know that it is for
7559 channel (library gets it from packet's Destination ID)).
7561 * Added silc_client_remove_from_channels into client library to
7562 remove a client from all channels it has joined to. Used when
7563 received SIGNOFF notify from server. Added also new function
7564 silc_client_replace_from_channels to replace old ID entry with
7565 new ID entry on all channels. Used when received NICK_CHANGE
7568 * Fixed ID Cache list handling in silc_idlist_get_client in
7569 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7570 to get (or query) client by ID.
7572 * Updated TODO list.
7574 * Added connection authentication status message defined by the
7575 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7576 support for these into the code in client and server side.
7578 * Added generic function silc_client_send_command to send any command
7579 with variable argument list. Application should use this function
7580 to send commands if the command functions provided by the library
7581 does not suite for the application's user interface needs.
7583 * Added new `failure' client operation. Application is notified about
7584 received failure packet if client is executing a protocol. In this
7585 case the protocol's execution has failed.
7587 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7588 is required by the protocol.
7590 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7591 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7594 * Added status flag to SilcSKE object to indicate realtime status
7595 of the SKE protocol.
7597 * Application receives now exactly same command reply arguments as
7598 the library receives from server. However, if ID is received the
7599 corresponding ID entry is returned to the application (eg. Client
7600 ID is mapped to correct SilcClientEntry entry and that is returned).
7601 Changed command_reply client operation due to this change.
7603 * Changed all ID's in commands and in command replys as ID Payloads.
7604 Change affected both client and server side codes.
7606 All ID's sent in SILC network (with execption of ID's in SILC
7607 Packet header) are sent in ID Payload to support variable length
7610 * Server now notifies nick changes and notifies all clients on
7611 the channels about the new nickname (about the new Client ID,
7614 * Implemented CMODE command to change channel modes. Supports all
7615 channel modes defined by the protocol specs except ban and invite
7616 lists. (Also, private channel key mode is supported but support for
7617 setting private channel key in client is missing, thus, this mode
7618 has no effect on client side (except that server requires that the
7619 client uses private channel key and normal channel traffic does not
7622 Also, invite mode works per se, but INVITE command does not work
7623 yet correctly, so you can set channel as invite only channel but
7624 inviting clients to the channel does not work (it is yet to be
7625 thought what's the best way to do it).
7627 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7628 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7629 Implemented CUMODE command to change user's mode on the channel.
7630 Supports all modes defined by the protocol specs.
7632 * Added NAMES command reply to return users modes on the channel.
7634 * Removed unnecessary and slow ciphers from lib/silccrypt.
7636 * Set SO_KEEPALIVE option to connection sockets by default.
7638 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7640 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7641 redefined the Notify Payload into protocol specs.
7643 * Added silc_id_payload_parse_id to get ID directly from raw
7646 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7648 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7649 accept searching by Client ID as well.
7651 * Added support for LEAVE and SIGNOFF notify types in client library.
7653 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7654 to parse ID Payload from raw data.
7656 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7658 * Added flags parameter into silc_ske_assemble_security_properties
7659 function in lib/silcske/silcske.[ch].
7661 * Changed notify client operation to fit better for notify messages
7662 sent by server. The notify payload received from server is now
7663 passed to the application (after parsing it to SilcNotifyPayload).
7664 It is application's responsibility to retrieve the arguments
7665 from the payload and show the message the way it wants. The message
7666 sent by server is implementation specific.
7668 * Changed public keys to comply with the protocol specification.
7669 Old public keys are not supported anymore and are not compatible.
7671 * Removed nickname from Channel Payload as the latest draft removed
7672 it. The client must resolve the nickname from the NAMES command
7673 reply received when it joined the channel.
7675 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7677 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7679 * Fixed some errors in protocol specification drafts.
7681 * Created lib/silccore/silcnotify.c to implement Notify Payload
7682 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7683 generic payloads described by protocol specifications. The file
7684 includes implementations for ID Payload and Argument Payload.
7686 * Changed Command Payload implementation to use the new Argument
7687 Payload. Changed command_xxxx_payload to command_payload_xxxx
7688 to comply with SILC coding conventions.
7690 * Added suppport for Argument Payload handling in Notify Payload
7691 implementation as protocol requires it. Added the new support
7692 into server and client lib as well.
7694 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Added support for multiple nicknames on same channel. [n] is
7697 added locally to the nickname if there are more than one same
7698 nicknames on the channel.
7700 * Server now sends all nicknames that matched WHOIS request.
7701 Client also shows the list received from server.
7703 * Added TOPIC command to client side. User can now set and show
7704 current topic on channel.
7706 * Added MOTD command to client and server. Also, server sends the
7707 motd when client connects to the server.
7709 * Changed version strings to comply ISO 8601.
7711 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7713 * Fixed protocol error handling in client library. It should now
7714 cope even if the SKE fails for some reason.
7716 * Made new protocol specification drafts for submitting to IETF.
7718 * Implemented TOPIC command to server in silcd/command.c.
7720 * Added two new notify types into lib/silccore/silcnotify.h:
7721 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7722 notify nickname change and topic setting/change on a channel.
7724 * API change of command_reply operation in client library. The
7725 application gets now the status type received from server as well.
7727 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7729 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7731 * Cras fixed and optimized the packet handling even further and
7732 it should work now. Minor change to the prototype of function
7733 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7735 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7737 * Added new function into lib/silcutil/silcschedule.[ch]:
7738 silc_schedule_with_fd to select() a specified fd. The function
7739 returns after timeout expires or data arrives or goes. The
7740 function is used by packet routines to wait that all data is
7741 received from network.
7743 * Fixed data reading from network in lib/silccore/silcpacket.c.
7744 The code now assures that all data is read from the fd and then
7745 continues packet processing. This was a bug fix since the code
7746 used to drop some data in some circumstances.
7748 * Added new function into lib/silcclient/client.[ch]:
7749 silc_client_start_key_exchange to start key exchange after
7750 connection has been established to server. The code internally
7751 now uses this funtion but its main purpose was to provide it
7752 for applications that perform their own connecting. After
7753 application has created a connection it merely calls this
7754 function to start the key exchange between client and server.
7755 The library takes care of everything else after that.
7757 Updated also lib/silcclient/README to explain the usage of
7760 * Do not send to application information that connection has
7761 been established. Application gets notified it by connect
7764 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7766 * Applied cras's patch to add silc_schedule_one function. The
7767 function runs scheduler once and returns.
7769 * Fixed the scheduler after cras messed it up. The timeout
7770 handling works now as it's supposed to work.
7772 * Added into lib/silccore/ silcnotify.h to include notify
7773 message types support. Changed silc_server_send_notify*
7774 functions, in server.[ch], to support those new notify types.
7775 Added the support for the notify types into client library,
7776 as well. Added new notify client operation into ops.h in
7779 * Changed silc_server_packet_send_to_channel to send normal
7780 packets instead of just channel message packets. The function
7781 is now used to send the notify packets to channels. It is not
7782 used to send channel message packets anymore, as server never
7785 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7786 va_arg()s as it seems to require it nowadays. I guess, if SILC
7787 is compiled with older va_arg() the new code should work anyway.
7789 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7791 * Splitted core library. Core library (lib/silccore) includes
7792 now only SILC protocol specific core (and common) components.
7793 Created new utility library (lib/silcutil) that includes more
7794 generic purpose stuff. The stuff for util library was taken
7795 from the old core library. This was minor and easy split.
7797 * Created SILC Client Library (lib/silcclient) that includes
7798 implementation of the SILC client without user interface. This
7799 was major move from silc/ directory. The code has been changed
7800 so that it is transparent towards the user interface. The
7801 silc/ directory includes now the same user interface as before
7802 and it uses the new client library. Read lib/silcclient/README.
7803 Basicly, the client library performs everything else related
7804 to SILC except user interface handling. Also, configuration
7805 files are considered to be part of user interface and library
7806 does not handle them.
7808 This change also changed a lot of structures, function naming etc.
7809 Most important change was that SilcClientWindow object was
7810 renamed to SilcClientConnection in the client library. Created
7811 also new file lib/silcclient/ops.h. Also added new files
7812 silc/local_command.[ch] and silc/client_ops.[ch].
7814 All these changes were made to make it easier for user interface
7815 designers to create what ever user interface for the SILC client
7818 It is also expected that the server will be moved to lib
7819 directory as well and SILC Server Library will be created;
7820 sometimes in the future.
7822 * Removed Local commands from lib/silccore/silccommand.h as
7823 they are application specific and new client library does not
7824 handle any of those anymore.
7826 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7827 old client implementation in silc/.
7829 * Added support for callback functions in SILC_LOG_* macros.
7830 Application can now set its own callbacks that will be called
7831 instead of using the default functions that will always print
7832 the debug messages to stderr (or stdout). Also, debugging can
7833 now be disabled by setting silc_debug to FALSE and re-enabled by
7834 setting it to TRUE. Note, that logging will still work even
7835 if debugging is disabled.
7837 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7838 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7839 silc_log_reset_debug_callbacks.
7841 * To enable debugging in silc client one must give now -d
7842 option on command line.
7844 * Changed silc_schedule_init to automatically allocate task queues
7845 if they are not allocated before calling it.
7847 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7849 * Added GMP 3.1 into math library.
7851 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7853 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7854 a channel in SILC network. The packet is used by servers and
7855 routers to notify other routers that user has left a channel.
7856 This little feature was missing until now. Added the feature
7857 to protocol specification as well.
7859 Added functions: silc_server_send_remove_channel_user and
7860 silc_server_remove_channel_user into server.[ch].
7862 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7863 lib/silccore/silcpacket.h. However, they are not implemented
7866 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7868 * Fixed joining to a channel and sending channel messages
7869 between server and router. The channel message sending should
7870 now work inside a cell.
7872 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7874 * Fixed the private message sending between server and router.
7875 The private message sending should now work inside a cell.
7877 * Added silc_server_replace_id into server.[ch] to replace
7878 existing ID in the SILC network.
7880 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7881 and silc_idlist_replace_server_id into idlist.[ch] in server.
7883 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7885 * Fixed the server to server connections. Server can again now
7886 connect to router. Router to router connections probably does
7889 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7891 * Added dynamic protocol registering support. Now protocols can
7892 registered and unregistered on the fly. Patch by cras.
7894 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7896 * Added lib/contrib directory to hold routines that some platforms
7897 don't have but are needed by SILC.
7899 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7900 into lin/contrib to provide getopt() and getopt_long() for
7901 those who don't have it.
7903 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7905 * Added AWAY command to client. When away message is set and
7906 client receives a private message packet the client automatically
7907 replies to the sender with the away message.
7909 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7910 bug seemed to be the cause of recent problems when compiling
7913 * Added version detection support to SKE protocol specification
7914 and added the new changes to the SKE implementation as well.
7915 There were other minor changes in the SKE protocol as well.
7917 Many changes in lib/silcske/silcske.[ch] and in
7918 lib/silcske/payload.[ch].
7920 * Added ^U functionality, clear input line. Patch from cras.
7922 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7924 * Mainly small bugfixes on core library. Fixed some debugging
7925 logging and buffer overflow in silclog.c.
7927 * Updated config.sub and config.guess on the distribution tree.
7929 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7931 * Added command lagging support in server. Client may execute
7932 commands now only once in two seconds.
7934 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7936 * Optimized packet reception. MAC computation and checking is now
7937 also more optimized. A lot previously duplicated code is now
7938 used as generic by both client and server.
7940 * Fixed key pair generation in clientutil.c
7942 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7944 * Added into lib/silccore/silcbufutil.[ch] new function;
7945 silc_buffer_realloc.
7947 * Moved generic packet sending/encryption functions to
7948 lib/silccore/silcpacket.[ch] from client and server. Some
7949 rewriting of the functions.
7951 * Moved all generic packet reception/decryption functions to
7952 lib/silccore/silcpacket.[ch] from client and server. The
7953 packet processing is now much cleaner in both client and server.
7954 These were major changes in both client and server.
7956 * Created many common functions in server to do packet sending.
7957 Previously code were duplicated a lot, this has been removed
7960 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7962 * Rewrote major parts of the ID cache system. Don't know
7963 whether it is better now or not but at least the API is more
7966 * Major rewrite on ID cache stuff on client because of the ID
7967 cache API changes. Added idlist.c to client.
7969 * Also major rewrite on ID cache stuff on server as well.
7970 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7971 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7972 in hand, instead they are all put into the ID cache system now.
7973 All server_idlist_* routines uses ID cache now instead of
7974 traversing its own lists (those lists does not exist anymore).
7975 SilcIDList though still exists. Also, SilcXXXEntry's are
7978 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7980 * Finally made the SKE implementation compliant to the protocol
7981 specification. All mp integers are now binary encoded as
7982 opposed being HEX encoded.
7984 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7987 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7988 functions: silc_[encode/decode]_pem. Also added function
7989 silc_encode_pem_file to PEM encode with newlines ('\n') for
7992 * SILC public keys are now encoded either PEM or binary. Same
7993 option is for private keys as well. By default private keys
7994 are binary encoded and public keys PEM encoded. Silly HEX
7995 encoding were removed.
7997 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7998 function to create fingerprints.
8000 * Fixed a bug in SHA1; does not change the original data anymore.
8002 * Partly implemented INFO command on client and server side.
8003 Fixed CLEAR command. Changes to SERVER command; show current
8004 server(s) when giving command without arguments. Added
8005 VERSION command to client.
8007 * Added check to server that unregistered connections cannot
8008 execute commands (unless it is specificly allowed).
8010 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8012 * Fixed screen refresh.
8014 * Fixed channel joining bug from client. On some circumstances
8015 client tried to join to a channel it had already joined.
8017 * Added public key verification process into client's protocol.c.
8018 The client now verifies the public key from user and saves
8019 it into ~./silc/serverkeys/ directory.
8021 Added into: clientutil.[ch]: silc_client_verify_server_key.
8023 * Changed SKE protocol's silc_ske_initiator_finish function
8024 to accept callback function that verifies the received public
8025 key. Removed old silc_ske_verify_public_key function.
8027 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8029 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8030 silc_pkcs_private_key[_data]_set.
8032 * Made the password and public authentication more cleaner in
8033 server's protocol.c.
8035 * Removed historic and obsolete protocol `channel_auth' from
8036 both client and server.
8038 * Removed wrong way of sending command status messages from
8039 server to client in server's command.c. The old way violated
8040 protocol specification.
8042 Changes to silccore/silccommand.[ch]: removed
8043 silc_command_encode_status_payload -> not needed anymore,
8044 changed silc_command_encode_payload_va to accept extra
8045 argument on variable argument list. The argument type must
8046 now be provided to the function. Also, added new function:
8047 silc_command_encode_reply_payload_va which is same as
8048 normal command_encode_payload_va except command status type
8049 is provided as extra argument.
8051 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8053 * Added ~./silc directory handling. The directory includes the
8054 public and private keys for the client.
8056 Added silc_client_check_silc_dir, silc_client_create_identifier
8057 and silc_client_load_keys.
8059 * Implemented SILC protocol compliant public key. Added public
8060 and private key saving to and loading from files.
8062 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8063 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8064 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8065 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8066 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8068 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8069 silc_pkcs_load_[public/private]_key.
8071 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8073 * Added silc_server_get_route (route.[ch]) to get connection
8074 data for the fastest route for given ID.
8076 * Implemented INVITE command on client and server. The command
8077 were re-defined in the SILC Protocol Specification and the
8078 implementation now complies with the specification.
8080 * Implemented PING command on client and server.
8082 * Implemented NAMES command on client and server. The server side
8083 supports currently only normal server not router server yet.
8084 Some changes to NAMES definition in SILC protocol specification.
8086 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8088 * Implemented LEAVE command on client and server.
8090 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8091 again. This change was made to the protocol as well. Server
8092 should not violate the protocol specification anymore.
8094 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8096 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8097 was tested. SOCKS4 was not but should work anyway.
